背景技术Background technique

The quality of the soldering strips will directly affect the current collection efficiency of photovoltaic modules. It has a great impact on the power of photovoltaic modules. The photovoltaic ribbon high-speed tin coating machine is mainly used to produce photovoltaic ribbons. Among them, the air knife is the main component in the high-speed tin coating machine to control the thickness of the ribbon. For the production of thin ribbons, the base layer is only 0.05mm, while the tin plating layer is only 0.07mm; in the existing technology, the air knife is usually improved, and even if the air volume can be controlled very accurately to blow off the excess tin liquid on the surface of the soldering strip, the thickness of the soldering strip cannot be well controlled; as the tin The liquid ratio, temperature, viscosity, etc. will all affect the adhesion of the tin liquid. Therefore, under the same wind force, the blown tin liquid cannot be well controlled. Therefore, there is an urgent need for a method that can accurately produce ultra-thin solder.

本发明取得的有益效果：Beneficial effects achieved by the present invention:
本发明通过设置打磨机构，通过打磨的方式实现超薄涂层的制作，生产效率高，且锡液的材料与砂轮材料硬度相差较大，砂轮使用寿命高。在两个打磨机构之间设置续料机构，克服了加工速度差的缺陷。The present invention realizes the production of ultra-thin coating by arranging a grinding mechanism, and has high production efficiency. Moreover, the material of the tin liquid and the grinding wheel material have a large difference in hardness, and the grinding wheel has a long service life. A feeding mechanism is installed between the two grinding mechanisms to overcome the defect of poor processing speed.
退火水箱采用浮动式防氧化管配合浮动部配合，随着液面的改变而同步移动，保证防氧化管下段基带不会与空气接触；同时配合固定套，保证上段基带不与空气接触；保证基带退火质量。通过增加补水机构，能够快速对水箱本体内进行补水，避免液位过低，无法满足光伏焊带的退火需求。补水机构中的水箱门通过连接杆与插孔配合，实现其关闭，巧妙的利用电磁铁作为致动器驱动撬板摆动，当水箱门需要打开时，控制电磁铁通电产生吸力，将撬板翘起后即可断电，节约资源，而且水箱门打开响应快，可靠性高。补水水箱与水箱本体摆动连接，当补水区注水过快时，蓄水区下降，补水区上升，避免补水区内的液体向补水区一端溢出。The annealing water tank adopts a floating anti-oxidation tube to cooperate with the floating part, which moves synchronously with the change of the liquid level to ensure that the lower base band of the anti-oxidation tube does not come into contact with the air; at the same time, it cooperates with a fixed sleeve to ensure that the upper base band does not come into contact with the air; to ensure that the base band Annealing quality. By adding a water replenishing mechanism, water can be quickly replenished in the water tank body to prevent the liquid level from being too low to meet the annealing needs of the photovoltaic welding strips. The water tank door in the water replenishment mechanism cooperates with the jack through the connecting rod to close it. The electromagnet is cleverly used as an actuator to drive the crowbar to swing. When the water tank door needs to be opened, the electromagnet is controlled to energize to generate suction and tilt the crowbar. The power can be cut off after starting up, saving resources, and the water tank door opens with fast response and high reliability. The water replenishment tank is swing-connected to the water tank body. When the water replenishment area is filled too fast, the water storage area drops and the water replenishment area rises to prevent the liquid in the water replenishment area from overflowing to one end of the water replenishment area.
辅助上锡装置在上锡时对基带表面进行压紧；并且辅助上锡装置结构简单，操作方便。预紧机构采用负压罐的结构，并且通过牵引线驱动连杆，避免锡炉内温度过热造成预紧机构失效。同时也能够通过控制罐体内的负压对预紧力进行调节。抽气孔上设置单向阀，使得气体只能从内向外流动，避免在断开抽气设备瞬间气体回入罐体内造成罐体内部气压变化。The auxiliary tin application device presses the surface of the base tape during tin application; the auxiliary tin application device has a simple structure and is easy to operate. The pre-tightening mechanism adopts the structure of a negative pressure tank and drives the connecting rod through the pulling wire to avoid the failure of the pre-tightening mechanism caused by overheating in the tin furnace. At the same time, the preload force can also be adjusted by controlling the negative pressure in the tank. A one-way valve is installed on the air extraction hole so that the gas can only flow from the inside to the outside to avoid gas returning to the tank and causing changes in the internal pressure of the tank when the air extraction equipment is disconnected.
锡炉通过U形管结构将上锡炉内的锡液引出，并且通过大面积的扁平容腔配合温度传感器进行测温，利用温度传感器浸没在锡液中以及锡液降低后温度传感器露出时的温度差，避免误报警。采用冷却冷却水管对测量本体外壁进行降温，降低固体热传递，减少锡液通过测量本体的侧壁将热传递至容腔内；同时配合散热风扇，在锡液液位高时，不会影响温度传感器测得的数值，但在锡液液位降低时，快速的将容腔内的热气排出，进而增加温度传感器测量竖直的差值；进一步避免误报警。The tin furnace leads out the tin liquid in the upper tin furnace through a U-shaped tube structure, and measures the temperature through a large-area flat cavity with a temperature sensor. The temperature sensor is immersed in the tin liquid and the temperature sensor is exposed after the tin liquid decreases. temperature difference to avoid false alarms. The cooling water pipe is used to cool the outer wall of the measuring body to reduce solid heat transfer and reduce the heat transfer of the tin liquid to the cavity through the side wall of the measuring body; at the same time, combined with a cooling fan, the temperature will not be affected when the tin liquid level is high. However, when the tin liquid level decreases, the hot air in the cavity is quickly discharged, thereby increasing the vertical difference measured by the temperature sensor; further avoiding false alarms.

By controlling The valve is adjusted to control the water supply speed of the water supply tank 2521 to the water tank body 251; preferably, the water supply speed of the water supply area 5213 is adjusted to be the same as the water supply speed of the water supply area 5213 to the water tank body 251. When the water replenishment speed in the water replenishment area 5213 is too fast, the liquid level in the water replenishment area 5213 reaches a certain height and flows into the water storage area 5214 through the first overflow port 5271 until the downward pressure of the water storage area 5214 can tilt the water replenishment area 5213. , at the same time, the contact switch is opened, the alarm device is activated, and the water injection into the water replenishment area 5213 is stopped to prevent the waste of water resources. If the staff cannot handle it in time, the liquid level in the water tank body 251 gradually decreases after use.

Lift up to separate the connecting rod 2523 from the jack. The water tank door 2522 is opened, and the water in the water replenishment area 5213 is quickly replenished into the water tank body 251 through the water replenishment port 5211. If the water consumption speed in the water tank body 251 is greater than the water replenishment speed, the liquid level in the water tank body 251 will also drop. When the liquid level drops to the lowest level, the actuator 2526 will also be triggered to open the water tank door 26 for water replenishment.

在一实施例中，如图13所示，锡炉8包括上锡炉81、连接管路82、延长管83、测量本体84测量本体84、温度传感器和报警器，测量本体84 测量本体84内设置有扁平状容腔，并且在其上表面和下表面设置与容腔连接的上接口和下接口，上锡炉81侧壁的底部开设连通孔，连接管路82的一端与连通孔连接，另一端与测量本体84测量本体84的下接口连接，延长管83连接测量本体84测量本体84的上接口，上锡炉81、连接管路82、测量本体84测量本体84和延长管83组合呈U形结构；由于U形管的两端液面同高，因此，延长管83内的高度即为上锡炉81内的高度。温度传感器设置在容腔内以测量容腔内的温度，并利用报警器报警，测量本体84 测量本体84外壁环绕设置冷却水管5，测量本体84测量本体84安装高度与上锡炉81的报警液位配合。冷却水管5与冷却设备连接。其报警原理为：上锡炉81内注入锡液，锡液从连接孔溢流至连接管路82、测量本体84测量本体84和延长管83内。上锡炉81设置有加热装置，对锡液不断加热，使其保持液态。当液位高时，温度传感器浸没在锡液中；当锡液不断降低，且低于温度传感器高度时，温度传感器测得的数值降低，通过单片机设置报警温度，当低于该温度时，控制报警器报警。但在实际使用时，锡液的温度会有较大的浮动，因此，单靠温度传感器测量温度以控制报警器报警，容易出现误报警。因此通过通过冷却水管5对测量本体84测量本体84侧壁不断降温(该降温并不会使得锡液凝固)。当锡液低于温度传感器，锡液仍然会通过测量本体84测量本体84的侧壁进行热量传递，容腔内仍然会保持一个较高的温度，因此，通过冷却水管5对测量本体84测量本体84 的侧壁进行降温，尽可能减少热量传递，此时，容腔内的温度会有一个较大的浮动，这样就能够尽可能避免误报警。In one embodiment, as shown in Figure 13, the tin furnace 8 includes an upper tin furnace 81, a connecting pipe 82, an extension tube 83, a measuring body 84, a temperature sensor and an alarm. The measuring body 84 measures inside the body 84 A flat cavity is provided, and an upper interface and a lower interface connected to the cavity are provided on its upper and lower surfaces. A communication hole is provided at the bottom of the side wall of the upper tin furnace 81, and one end of the connecting pipe 82 is connected to the communication hole. The other end is connected to the lower interface of the measuring body 84. The extension tube 83 is connected to the upper interface of the measuring body 84. The upper tin furnace 81, the connecting pipeline 82, the measuring body 84, the measuring body 84 and the extension tube 83 are combined to form a U-shaped structure; since the liquid levels at both ends of the U-shaped tube are at the same height, the height inside the extension tube 83 is the height inside the upper tin furnace 81 . The temperature sensor is installed in the cavity to measure the temperature in the cavity and uses an alarm to alarm. The measuring body 84 is surrounded by a cooling water pipe 5 on the outer wall of the measuring body 84. The measuring body 84 measures the installation height of the measuring body 84 and the alarm fluid of the tin furnace 81. Cooperation. The cooling water pipe 5 is connected to the cooling equipment. The alarm principle is as follows: tin liquid is injected into the tin furnace 81, and the tin liquid overflows from the connecting hole to the connecting pipe 82, the measuring body 84, the measuring body 84 and the extension tube 83. The tin furnace 81 is provided with a heating device to continuously heat the tin liquid to keep it in a liquid state. When the liquid level is high, the temperature sensor is immersed in the tin liquid; when the tin liquid continues to decrease and is lower than the height of the temperature sensor, the value measured by the temperature sensor decreases, and the alarm temperature is set by the microcontroller. When it is lower than this temperature, the control The alarm sounds. However, in actual use, the temperature of the tin liquid will fluctuate greatly. Therefore, relying solely on the temperature sensor to measure the temperature to control the alarm is prone to false alarms. Therefore, the side wall of the measuring body 84 of the measuring body 84 is continuously cooled through the cooling water pipe 5 (this cooling will not cause the tin liquid to solidify). When the tin liquid is lower than the temperature sensor, the tin liquid will still transfer heat through the side wall of the measuring body 84 and the chamber will still maintain a higher temperature. Therefore, the cooling water pipe 5 is used to measure the measuring body 84 The side wall of 84 is cooled down to reduce heat transfer as much as possible. At this time, the temperature in the cavity will have a larger fluctuation, so that false alarms can be avoided as much as possible.
在上述实施例中，如图13所示，在测量本体84测量本体84的下表面也可以设置冷却水管，进一步隔绝固体的热传递。In the above embodiment, as shown in FIG. 13 , a cooling water pipe may also be provided on the lower surface of the measuring body 84 to further isolate the heat transfer of the solid.
在一实施例中，如图13所示，上接口与下接口设置在测量本体84测量本体84的边缘处。In one embodiment, as shown in FIG. 13 , the upper interface and the lower interface are provided at the edge of the measuring body 84 .

在一实施例中，如图13所示，还包括散热风扇86，测量本体84测量本体84的上表面设置冷却机构87，延长管83设置在冷却机构87上，散热风扇86设置在延长管83的上端。当锡液充足时，冷却机构87上的延长管 83内充满锡液，通过散热风扇86对延长管83内进行降温，由于其内部充满锡液，对于温度传感器的测量值基本无影响。当液位降低延长管83及容腔内为空腔，通过散热风扇86将内部热气抽走，对容腔内进一步降温，使得温度差值更大，进一步避免误报警。In one embodiment, as shown in Figure 13, a cooling fan 86 is also included. A cooling mechanism 87 is provided on the upper surface of the measuring body 84. The extension tube 83 is provided on the cooling mechanism 87, and the cooling fan 86 is provided on the extension tube 83. the upper end. When the tin liquid is sufficient, the extension tube 83 on the cooling mechanism 87 is filled with tin liquid, and the extension tube 83 is cooled by the cooling fan 86. Since the inside of the extension tube 83 is filled with tin liquid, it has basically no impact on the measured value of the temperature sensor. When the liquid level decreases, the extension tube 83 and the cavity are hollow, and the heat dissipation fan 86 is used to evacuate the internal hot air to further cool down the cavity, making the temperature difference larger and further avoiding false alarms.
在一实施例中，如图13所示，报警器包括蜂鸣器、警报灯中的一种或其组合。In one embodiment, as shown in Figure 13, the alarm includes one of a buzzer, a warning light, or a combination thereof.
在一实施例中，如图13所示，温度传感器位于冷却机构87与测量本体84测量本体84的侧壁之间，且远离上接口。使得温度传感器远离热源，进而增加温度差值。In one embodiment, as shown in FIG. 13 , the temperature sensor is located between the cooling mechanism 87 and the side wall of the measuring body 84 and away from the upper interface. Keep the temperature sensor away from the heat source, thereby increasing the temperature difference.
在一实施例中，如图13所示，散热风扇86与延长管83之间设置有间隙。避免由于散热风扇86抽风流量过大，将锡液向上吸引。In one embodiment, as shown in FIG. 13 , a gap is provided between the cooling fan 86 and the extension tube 83 . Avoid drawing the tin liquid upward due to excessive air flow of the cooling fan 86.
