[0002] A PCB board, that is, a printed circuit board, also known as a printed wiring board, etc., is an important electronic component. As a support for electronic components, it provides electrical connections between electronic components. Classified by the number of layers, it is divided into three major categories: single-sided boards, double-sided boards, and multi-layer circuit boards. During the processing of PCB boards, it is necessary to perform pin withdrawing processing on the PCB boards through a pin withdrawing machine.

[0003] As disclosed in a Chinese patent: a pin withdrawing machine for PCB boards, application number: CN202122637864.2, which includes an operating table. A pin discharging hole is opened at the top of the operating table. A support seat is movably connected to the top of the operating table. The inner bottom wall of the support seat is fixedly connected with a pin withdrawing machine body. The bottom of the operating table is fixedly connected with support legs, and one end of the support legs is fixedly connected with a support bottom plate. This pin withdrawing machine for PCB boards can achieve the purpose of good clamping effect. When performing pin withdrawing operation on the PCB board, it can perform good clamping and limiting treatment on it. The clamping operation is simple and the structure is reasonable, improving the stability of the PCB board, reducing the situation that the PCB board is prone to displacement during pin withdrawing treatment, and the use quality of the PCB board will not be greatly affected. The working efficiency of the pin withdrawing machine body is also improved to a certain extent, and the user's demand for limiting the position of the PCB board during pin withdrawing operation can be met.

[0004] However, in the above technical solution, after the pin withdrawing processing of the PCB board is completed, it is necessary to discharge the PCB board. When discharging in the above technical solution, first, a person needs to lift the clamping plates on both sides and keep the clamping plates always in the lifted state during the discharging process, and then another person can take out the PCB board from the pin withdrawing machine to complete the discharging. This not only takes a long time, but also at least two people need to cooperate to perform the discharging, and the required manpower is relatively high. Summary of the Utility Model

[0005] The main purpose of the utility model is to provide a material discharging device for a pin withdrawing machine in PCB board processing, which can effectively solve the problem in the background technique that after the pin withdrawing processing of the PCB board is completed, it is necessary to discharge the PCB board. When discharging in the above technical solution, first, a person needs to lift the clamping plates on both sides and keep the clamping plates always in the lifted state during the discharging process, and then another person can take out the PCB board from the pin withdrawing machine to complete the discharging. This not only takes a long time, but also at least two people need to cooperate to perform the discharging, and the required manpower is relatively high.

[0006] To achieve the above object, the technical solution adopted by the present utility model is as follows:

Above one side of the lower clamping plates, there is an upper clamping plate. On the lower clamping plates, there are sliding grooves, and in the sliding grooves, there is a material discharging plate. On one side of the upper clamping plate, there is a first inclined surface. Above one side of the upper clamping plate, a plurality of springs and a plurality of guiding sliding columns are fixedly arranged. On one side of the springs, there is a top plate. Between the lower clamping plate and the upper clamping plate, there is a plate.

[0008] Preferably, the length of the lower clamping plate is greater than that of the upper clamping plate. The guiding sliding columns are slidably connected with the top plate, and the top plate is fixedly installed on the pin withdrawing machine.

[0014] (1) After the processing of the present utility model is completed, by pulling the material discharging plate base through the buckling groove to move the material discharging plate base in a direction away from the first inclined surface, then the material discharging plate base drives the sliding plates to move, the sliding plates drive the pushing blocks to move, and the pushing blocks squeeze the first inclined surface through the second inclined surface, so that the upper clamping plate moves in a direction away from the lower clamping plate. Subsequently, the pushing blocks continue to move, so that the pushing blocks are located between the upper clamping plate and the lower clamping plate, and fix the distance between the upper clamping plate and the lower clamping plate, thereby releasing the extrusion fixation of the upper clamping plate on the plate. Then, the pushing blocks continue to move, the outer walls of the pushing blocks are attached to the plate, and then the plate is pushed by the pushing blocks to move, so that the plate gradually leaves between the upper clamping plate and the lower clamping plate, thus completing the material discharging. By a worker pulling the material discharging plate, the plate can be quickly withdrawn from the working area, reducing the time and labor required for material discharging and improving the production efficiency.

Specific embodiments

[0019] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present utility model.

[0020] As Figure 1 and Figure 2 shown, an unloading device of a pin withdrawing machine for PCB board processing includes a pin withdrawing machine 1. A plurality of lower clamping plates 2 are fixedly arranged on the pin withdrawing machine 1. An upper clamping plate 3 is arranged on one side above the lower clamping plate 2. A sliding groove 4 is arranged on the lower clamping plate 2. An unloading plate 5 is arranged in the sliding groove 4. A first inclined surface 6 is arranged on one side of the upper clamping plate 3. A plurality of springs 7 and a plurality of guiding slide posts 8 are fixedly arranged on one side above the upper clamping plate 3. A top plate 9 is fixedly arranged on one side of the spring 7. A plate 10 is arranged between the lower clamping plate 2 and the upper clamping plate 3.

[0021] As Figure 3 shown, in another embodiment of the present utility model, the unloading plate 5 includes an unloading plate base 501, and a buckling groove 502 is arranged on the unloading plate base 501;

[0022] On one side of the blanking plate base 501, several sliding plates 503 are provided. On the sliding plates 503, pushing blocks 504 are provided. On the pushing blocks 504, second inclined surfaces 505 are provided. On the second inclined surfaces 505, several balls 506 are provided. When it is necessary to unload the processed plate 10, first, the blanking plate base 501 is pulled to move through the buckle groove 502, so that the blanking plate base 501 moves away from the first inclined surface 6. Then, the blanking plate base 501 drives the sliding plate 503 to move, the sliding plate 503 drives the pushing block 504 to move, and the pushing block 504 squeezes the first inclined surface 6 through the second inclined surface 505. The friction is reduced through the balls 506, so that the upper clamping plate 3 moves away from the lower clamping plate 2, and the spring 7 deforms, releasing the extrusion and fixation of the upper clamping plate 3 on the plate 10. Subsequently, the pushing block 504 continues to move, the outer wall of the pushing block 504 fits with the plate 10, and then the plate 10 is pushed to move through the pushing block 504, so that the plate 10 gradually leaves between the upper clamping plate 3 and the lower clamping plate 2, thus completing the unloading.

[0023] The working principle of the unloading device of the pin withdrawing machine for PCB board processing:

[0024] During use, first, the pin withdrawing machine 1 is used to process the plate 10 clamped and fixed between the lower clamping plate 2 and the upper clamping plate 3. After the processing is completed, the blanking plate base 501 is pulled to move through the buckle groove 502, so that the blanking plate base 501 moves away from the first inclined surface 6. Then, the blanking plate base 501 drives the sliding plate 503 to move, the sliding plate 503 drives the pushing block 504 to move, and the pushing block 504 squeezes the first inclined surface 6 through the second inclined surface 505, so that the upper clamping plate 3 moves away from the lower clamping plate 2, and the spring 7 deforms and is guided by the guiding sliding column 8. Subsequently, the pushing block 504 continues to move, so that the pushing block 504 is located between the upper clamping plate 3 and the lower clamping plate 2, and the distance between the upper clamping plate 3 and the lower clamping plate 2 is fixed, thus releasing the extrusion and fixation of the upper clamping plate 3 on the plate 10. Then, the pushing block 504 continues to move, the outer wall of the pushing block 504 fits with the plate 10, and then the plate 10 is pushed to move through the pushing block 504, so that the plate 10 gradually leaves between the upper clamping plate 3 and the lower clamping plate 2, thus completing the unloading. By a worker pulling the blanking plate 5, the plate 10 can be quickly withdrawn from the working area, reducing the time and labor required for unloading and improving the production efficiency.

[0025] Obviously, the above-mentioned embodiments of the present utility model are only examples for clearly explaining the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation manners here. Any obvious changes or modifications derived from the technical solutions of the present invention still fall within the protection scope of the present invention.
