For example, the chip removing apparatus 100 provided in this embodiment may be used in manufacturing a multi-layer PCB (Printed Circuit Board ) board to realize connection between the multi-layer PCB boards.
The performance of the chip removing device has a crucial influence on the stamping result and the performance of the product obtained after stamping. For example, as the multilayer board in the PCB industry develops to a high level, high performance and high security, especially as the application of the PCB in various fields such as automobile production, communication equipment, medical treatment, aerospace, power supply and the like is wider, the user also puts higher demands on the performance of the multilayer PCB. When preparing multilayer PCB board, pressfitting is one of the indispensable processes, pressfitting process also has crucial influence to multilayer PCB board's quality and performance. The problem of rejection in the lamination process is often caused by lamination of the inner layer foreign matter and the inner layer short circuit. The rivet scraps generated in the lamination process are the primary reasons for causing foreign matters in the lamination inner layer or short circuits in the inner layer. At present, an economic and reliable device or method for effectively solving the problem of micro-short or short circuit of the inner layer of the multilayer PCB caused by rivet scraps is lacking in the related art. It is therefore necessary to provide a scrap removing device which prevents rivet scraps from entering the rivet product.
In view of this, the present embodiment provides a chip removing apparatus 100 capable of preventing rivet chips from entering a rivet product. The chip removing apparatus 100 includes: the chip removing apparatus body 110 and the duct structure 120. The chip removing apparatus body 110 is provided with a first vent 112 and a second vent 114; the air duct structural member 120 is accommodated in the chip removing device body 110, and is provided with an air duct 130; wherein the first and second vents 112 and 114 are respectively in communication with the air duct 130 such that gas flows between the first vent 112, the air duct 130, and the second vent 114.
Wherein the chip removing device further comprises a gas driving device 170. The gas driving device 170 is in communication with the second vent 114, and is adapted to deliver gas to the second vent 114 or to adsorb gas through the second vent 114. For example, the gas driving device 170 may be a gas source device capable of generating and delivering gas, or a negative pressure device capable of adsorbing gas to form a negative pressure.

Wherein the chip removing apparatus 100 is partially or entirely embedded in the console assembly 210 and disposed below the stapling assembly 220. In use, the chip removing apparatus 100 is internally threaded and secured with a punch. The stapling assembly 220 applies a rivet vertically above the punch so that the punch completes a punch-through operation on the rivet. In this process, the rivet may generate debris such as metal chips. In order to prevent impurities such as metal scraps from entering the riveted products, the chip removing device 100 provided in this embodiment is provided with the first ventilation opening 112 and the second ventilation opening 114 on the chip removing device body 110, and an air duct structural member 120 is accommodated in the chip removing device body 110, and the air duct structural member 120 is provided with the air duct 130. Because the first ventilation opening 112 and the second ventilation opening 114 are respectively communicated with the air duct 130, the air flow can be utilized to absorb or blow away impurities such as metal scraps, thereby preventing the impurities such as metal scraps from entering the riveted product.
Specifically, as shown in fig. 1 and 2, in the chip removing apparatus 100 provided in the present embodiment, the chip removing apparatus 100 has a cylindrical structure. The first ventilation opening 112 is disposed on the top surface of the chip removing apparatus 100, and the second ventilation opening 114 is disposed on the bottom surface or the side wall of the chip removing apparatus 100. In order to allow an air flow in the chip removing device 100, an air source or a negative pressure device may be connected to the second air vent 114. When the air source is connected to the second air vent 114, air can be delivered from the second air vent 114 into the chip removing device 100, and the air can be driven to be discharged from the first air vent 112, so as to blow off impurities such as metal chips. When the negative pressure device is connected to the second air vent 114, the air around the first air vent 112 may be driven to drive the impurities such as metal chips and the like to enter the chip removing device 100 together, and the impurities such as metal chips and the like are discharged from the second air vent 114, so as to be adsorbed and discharged.

The number of the first ventilation openings 112 may be plural. For example, as shown in fig. 1, the first ventilation opening 112 is a circular grid structure. The design of the grid structure can ensure smooth circulation of the gas, and can form larger negative pressure at the periphery of the first ventilation opening 112 when absorbing sundries such as metal scraps by utilizing the flow of the air so as to quickly and effectively absorb the sundries such as the metal scraps.
In order to facilitate the installation and placement of the air duct structural member 120, the chip removing apparatus body 110 may be provided in a detachable and separable structure. For example, as shown in fig. 1, the chip removing apparatus body 110 includes a base 116 and a cover 118 which are disposed up and down and detachably connected by screws. The air duct structure 120 is accommodated in a space formed by the base 116 and the cover 118.
In order to improve the efficiency of the airflow and thus improve the effect of absorbing or blowing away the impurities such as metal chips, the air duct 130 is disposed on the air duct structural member 120 in this embodiment. The air duct 130 is a plurality of ravine structures and/or groove structures formed on the inside or surface of the air duct structural member 120. A plurality of the ravine structures and/or groove structures are in communication with each other such that an air flow flows between the ravine structures and/or groove structures to create a greater air pressure around the first vent 112.
