With the development of electronic technology, various electronic devices use circuit boards. In addition, circuit boards are widely used in electrical equipment. With the increasing usage of electrical appliances, the production of circuit boards has become more large-scale and streamlined. In the process of circuit board processing, many processes are required, such as drilling, etching, etc. In different processes, the recycling of circuit boards is an essential process. During the manufacturing process of circuit boards, according to different processes at each step, the circuit boards need to be transported from one device to another. Among them, a receiving machine is a frequently used device in the entire circuit board production line, which is used to neatly store a certain number of circuit boards in a receiving box for use in the next process. However, during the transportation of circuit boards, the position of the circuit boards cannot be guaranteed to be stable, and the existing receiving machines do not have an alignment mechanism, which easily damages the circuit boards due to misalignment during the receiving process.

The suction nozzles 167 are used to adsorb the circuit boards to avoid hard collision with the circuit boards and cause damage to the circuit boards.

[0030] Specifically, referring to Figures 1 to 6 As shown, the material transporting device 200 is disposed on the X-axis linear module 140, and the X-axis linear module 140 drives the material transporting device 200 to move along the direction of the X-axis linear module 140. The material transporting device 200 includes a telescopic assembly 210 and a suction assembly 220. One end of the telescopic assembly 210 is connected to the X-axis linear module 140.

The lifting module 320 is used to drive the bearing module 310 to rise or fall. The lifting module 320 is arranged at the driving end of the telescopic module 330. The telescopic module 330 is used to drive the lifting module 320 and the bearing module 310 to move in the horizontal direction. The auxiliary board loading mechanism 400 includes a driving module 410 and an auxiliary loading module 420. The auxiliary loading module 420 is arranged at the driving end of the driving module 410. The driving module 410 is used to drive the auxiliary loading module 420 to extend into or retract from the main board loading mechanism 300. In the present embodiment, after the circuit board is aligned on the positioning device 100, the circuit board is driven by the material transport device 200 to move onto the board collecting device 700, so that the circuit board falls into the carrier module 310. As the number of circuit boards in the carrier module 310 continues to increase, the lifting module 320 drives the carrier module 310 to descend, making room for the circuit boards subsequently driven by the material transport device 200, so that the circuit boards are stacked on the carrier module 310. When the carrier module 310 is fully loaded, the auxiliary load module 420 extends into the carrier module 310 under the drive of the drive module 410, replacing the carrier module 310 to bear the load. The telescopic module 330 drives the lifting module 320 to extend outward, driving the carrying module 310 to extend outward, and collects the circuit boards on the carrying module 310. After the collection is completed, the carrying module 310 is reset and receives the circuit boards on the auxiliary carrying module 420. At this time, the auxiliary carrying module 420 is reset under the drive of the driving module 410, and the carrying module 310 continues to carry the circuit boards transmitted by the material transporting device 200, so that the material transporting device 200 can operate continuously without stopping for collecting materials, thereby improving the board collection efficiency and enabling the entire production line to operate continuously and stably.

The driving module 410 drives the auxiliary carrier plates 422 to extend into or retract from the carrier module 310 through the clearance openings 313. In this embodiment, the carrier plates 312 are linearly arrayed on the connection plate 311, so that when the circuit board falls onto the carrier plates 312, the force can be evenly distributed. At the same time, when the carrier module 310 discharges materials, it can pass through the gap between two adjacent carrier plates 312 to lift the circuit board on the carrier module 310, avoiding the need for dragging and discharging, which may cause wear to the bottom circuit board. When the carrier module 310 is reset, the carrier plates 312 and the auxiliary carrier plates 422 are arranged alternately, and the clearance openings 313 play a clearance role, enabling each carrier plate 312 to pass through the gap between two adjacent auxiliary carrier plates 422 to lift the circuit board on the auxiliary carrier plates 422, so that the auxiliary carrier plates 422 can be reset, thereby realizing board collection without stopping the machine.

When the carrying module 310 is full and needs to be unloaded, it drives the carrying module 310 to extend for unloading. After unloading is completed, it retracts to continue carrying the circuit board, realizing board collection without stopping the machine. By driving the lifting screw 323 to rotate through the lifting drive motor 322, the rising or falling of the carrying module 310 can be controlled. When the carrying module 310 receives the circuit board conveyed by the conveying device, it can slowly descend to avoid direct collision and scratching between two circuit boards caused by excessive impact force during circuit board unloading.
