Description

Technical Field

[0001] The invention relates to the technical field related to circuit board punching, and in particular to an improved circuit board punching device. Background Art

[0002] The punching process of circuit boards requires the use of circuit board punching equipment. The processing process is to manually position the unpunched circuit boards into the circuit board punching equipment. The circuit board punching equipment has multiple workstations and multiple drill bits, and it is necessary to manually place the circuit boards several times. After the punching is completed, the circuit boards are manually taken out and then rearranged. Although the punching process of the circuit boards can be realized, the manual placement of the circuit boards takes a long time, resulting in relatively low circuit board processing efficiency. The simultaneous start of multiple circuit board punching requires more workers, resulting in higher labor costs. Summary of the invention

[0003] In order to overcome the existing technical defects, the purpose of the present invention is to provide an improved circuit board punching device to solve the above technical problems.

[0004] The technical solution adopted by the present invention to solve the technical problem is as follows:

[0005] According to one aspect of the present invention, an improved circuit board punching device is designed, comprising:

[0006] Temporary storage and loading rack, used to receive materials for temporary storage and loading;

[0007] The main conveyor line, whose loading end corresponds to the discharging end of the temporary storage loading shelf, is used to receive the materials outputted from the temporary storage loading shelf;

[0008] A punching machine platform is arranged on one side of the main conveying line, and the punching machine platform is provided with a plurality of drilling stations and a plurality of drilling machines, and a loading port is arranged at the rear side;

[0009] A branch conveyor line is arranged across the punching machine platform and is used to receive materials conveyed by the transfer mechanism on the main conveyor line;

[0010] A docking mechanism, which is provided in plurality and installed on the branch conveyor line, and is used to synchronously output the materials received on the branch conveyor line;

[0011] The plate feeding and receiving mechanism is arranged at the rear side of the punching machine, and is used for receiving the material output by the docking mechanism and conveying the material to one side of the punching machine, so that the material taking mechanism in the punching machine can take the material and place it on the drilling station in the punching machine. The material taking mechanism is also used for taking the material after the punching is completed and conveying it to the plate feeding and receiving mechanism, so that the plate feeding and receiving mechanism can convey the punched material to the docking mechanism, and the docking mechanism will then place the punched material on the branch conveyor line for output.

[0012] By adopting the above technical solution, automatic loading and unloading of board materials such as circuit boards can be realized. Compared with the existing method of manually loading the boards into the punching machine and manually taking away the punched circuit boards, loading and unloading takes less time, thereby improving the processing efficiency of board materials such as circuit boards, using fewer workers, and saving labor costs.

[0013] In order to better solve the above technical defects, the present invention also has a better technical solution:

[0014] In some embodiments, the main conveyor line includes multiple conveying mechanisms arranged horizontally, and a transfer mechanism arranged at the discharge end of the conveying mechanism. The feed end of the branch conveyor line corresponds to the transfer mechanism. The discharge end of each of the conveying mechanisms is equipped with a correction mechanism, which is used to center the conveyed material.

[0015] In some embodiments, the temporary storage loading shelf includes:

[0016] The frame has a plurality of first-layer shelves for placing materials arranged vertically in the middle;

[0017] The stacking mechanism is arranged at the left end of the frame and vertically slides with the frame through a guide assembly. A first driving device for driving the stacking mechanism to rise and fall is arranged between the stacking mechanism and the frame. When the first driving device drives the stacking mechanism to rise to a preset height, the stacking mechanism corresponds to a first shelf and is used to place the taken material on the corresponding first shelf.

[0018] The feeding mechanism is arranged at the right end of the frame and vertically slides with the frame through the guide assembly. A second driving device for driving the feeding mechanism to rise and fall is arranged between the feeding mechanism and the frame. When the second driving device drives the feeding mechanism to rise to a preset height, the feeding mechanism corresponds to a first shelf thereof, and is used to take the material on the corresponding first shelf and feed it to the main conveyor line. The taken material can be placed on the first shelf through the coding mechanism, and the material can be cached through the first shelf. The material on the first shelf can be taken away for feeding through the feeding mechanism, so as to realize automatic material feeding and complete the feeding automatically. The feeding efficiency is relatively high, which can improve the processing efficiency.

The longitudinal drive device is drivingly connected to one of the correction frames to drive the correction frame to move longitudinally. When the material is conveyed to between the two correcting pieces through the conveying mechanism, the longitudinal driving device drives the correcting frame connected to it to move and drives the correcting piece on it to approach the material. At the same time, the linkage component can link another correcting frame to move and drive the correcting piece on it to approach the material synchronously. The two correcting pieces approach the material and contact both ends of the material to achieve centering correction of the material, thereby ensuring the normal conveying of the material and solving the problem of material deflection and inability to convey normally during conveying.
