Background
Glass loading devices are an integral part of the modern manufacturing industry, especially in the fields of flat panel displays, automotive manufacturing, etc. Along with the improvement of the production automation level, the efficient material handling system has important significance for improving the overall efficiency of the production line.
In conventional glass packages, which include a plurality of stacked glass sheets, spacers are placed between adjacent glass sheets to prevent the glass sheets from being bumped or rubbed against each other. When the glass is fed, the glass and the spacer are separated manually, and then the glass is fed. However, manual operation is not only labor-intensive and inefficient, but also prone to sudden accidents.
In order to avoid the problem of manual operation, the grabbing work of glass and the isolating sheets is generally performed by a manipulator alternately at present, so that the separation of the glass and the isolating sheets and the feeding work of the glass are completed. However, a single manipulator can only grasp glass or a spacer, the simultaneous grasping cannot be realized, the feeding efficiency is low, and a plurality of manipulators are adopted to work simultaneously, so that the cooperativity among the manipulators is required to be considered, and the feeding complexity and the error probability are increased. Secondly, the cost of the manipulator is high, and some small and medium-sized factories are difficult to equip.

The lifting unit 12 includes a mounting frame 121, a screw, a driving member 122, a guide rail 123, a sliding seat 124, and a lifting frame 125. The guide rail 123 is vertically arranged on the mounting frame 121, the sliding seat 124 is in sliding connection with the guide rail 123, the lead screw is rotationally connected with the mounting frame 121, and the nut of the lead screw is connected with the sliding seat 124. The driving member 122 is coupled to the screw and serves to raise and lower the sliding seat 124 by driving the screw to rotate. The driving member 122 may be a motor, which may be directly connected to the lead screw, or may be connected to the lead screw through a belt and pulley.
The lifting frame 125 is disposed on the sliding seat 124, when the lifting frame 125 rises along with the sliding seat 124, the lifting frame 125 can pass through a gap between the conveying rollers of the first conveying unit 11, so that the material frame 200 placed on the first conveying unit 11 and the workpiece are lifted up together, and the material frame 200 and the workpiece are lifted up to the grabbing station.

Specifically, the air cylinder 33 is lifted and lowered by driving the mounting plate 32, so that the gripping unit 34 can approach the glass and grip the glass. The grabbing unit 34 may be a sucker connected with a negative pressure pipeline, and the glass is grabbed by the sucker.
In addition, the spacer grabbing component 4 can be designed with reference to the glass grabbing component 3, and the spacer is sucked and grabbed through the sucker.
Example 2
This embodiment differs from embodiment 1 in that the glass gripping assembly 3 is modified.
As shown in fig. 4 to 5, in particular, a limit rod 35 is vertically disposed on the mounting plate 32, and the limit rod 35 is slidably connected to the support plate 31. The stop lever 35 is used to prevent the mounting plate 32 from swinging laterally when it is lifted.
The grasping unit 34 includes a sleeve 341, a piston 342, a connecting rod 343, a rubber ring 344, and a pressing block 345.
The sleeve 341 is vertically arranged below the mounting plate 32, the bottom of the sleeve 341 is provided with an opening, the rubber ring 344 is arranged at the bottom of the sleeve 341, the piston 342 is slidably arranged in the sleeve 341, the piston 342 divides the interior of the sleeve 341 into an upper chamber and a lower chamber, and the piston 342 is connected with the mounting plate 32 through the connecting rod 343. The pressing block 345 is arranged on the connecting rod 343, and the pressing block 345 is arranged above the sleeve 341.
The cylinder 33 descends by driving the mounting plate 32 so that the connecting rod 343 and the piston 342 descend. The top of the inner wall of the sleeve 341 is provided with a limit protrusion 3411 to prevent the sleeve 341 from being separated from the piston 342. After the sleeve 341 descends following the piston 342 and makes the rubber ring 344 at the bottom of the sleeve 341 contact with the glass surface, the connecting rod 343 and the piston 342 further descend, so that the pressing block 345 on the connecting rod 343 contacts with the top of the sleeve 341 and presses down the sleeve 341, and the rubber ring 344 can be tightly attached to the glass. Subsequently, the connection rod 343 and the piston 342 rise, the space of the lower chamber becomes large, and the lower chamber is under negative pressure, thereby being able to adsorb glass.
Further, the grabbing unit 34 further comprises two limiting blocks 346, the two limiting blocks 346 are arranged on the connecting rod 343, the pressing block 345 is slidably connected with the connecting rod 343, and the pressing block 345 is located between the two limiting blocks 346.
When the rubber ring 344 at the bottom of the sleeve 341 is contacted with the surface of the glass, the pressing block 345 can be contacted with the top of the sleeve 341 along with the descending of the connecting rod 343, and when the connecting rod 343 is further descended, the limiting block 346 positioned above can press the sleeve 341 down, so that the rubber ring 344 is tightly attached to the glass. When the connecting rod 343 and the piston 342 rise, the pressing block 345 does not immediately follow the rising of the connecting rod 343, but the pressing block 345 does not rise and separate from the sleeve 341 until the lower limiting block 346 contacts the bottom of the pressing block 345. This design prevents the rubber ring 344 from disengaging from the glass surface at the moment the piston 342 rises. After the piston 342 rises a certain distance, the negative pressure can make the rubber ring 344 firmly adsorbed on the glass, and at this time, even though the pressing block 345 is separated from the sleeve 341, the adsorption of the glass is not affected.
Compared with the traditional suction cup suction, the glass suction mode of the embodiment has the following advantages:
1. The suction force can not be flexibly changed according to the weight of glass by the traditional suction cup, so that the suction force is stable, the total suction force of the suction cup is usually far greater than the gravity of the glass, and damage can be caused to some fragile glass. While the present embodiment can flexibly change the magnitude of the suction force by the relative movement between the piston 342 and the sleeve 341. Specifically, the glass applies downward force to the sleeve 341 and the rubber ring 344, so that the space of the lower chamber becomes larger, and the larger the gravity of the glass is, the larger the space of the lower chamber becomes, and the larger the space of the lower chamber is, the larger the adsorption force due to the negative pressure is. Therefore, the embodiment can automatically change the suction force according to the gravity of the glass, and the total suction force is basically equal to the gravity of the glass, so that the glass is prevented from being damaged due to overlarge suction force.
2. The glass grabbing mode of the embodiment does not need to rely on parts such as an air pump and a negative pressure pipeline, so that cost is saved, and the problem that the negative pressure pipeline is more and disordered is avoided.
