[0002] In the field of electronic component processing, a circuit board is one of the common components. A circuit board is a carrier on which many electronic components are installed to achieve functions such as circuit connection and control. During the production of a circuit board, it is often necessary to perform a punching operation on the circuit board to facilitate the installation of electronic components or circuit connection.

[0003] After retrieval, it is found that in the prior art, the general punching auxiliary tool for a circuit board directly places the circuit board on the workbench for extrusion and fixation first, and then performs the punching work through a punching machine. However, since there are many small electronic components on the circuit board and the surface of the circuit board directly contacts the workbench surface, once the staff exerts excessive force, it is very likely to damage the electronic components on the circuit board. In addition, when it is necessary to process on the other side, manual replacement is required, and it is also easy to touch the electronic components on the circuit board during the replacement process, resulting in their damage and affecting their normal use. Summary of the Utility Model

[0004] In order to make up for the above deficiencies, the utility model provides a visual positioning device for punching holes in a circuit board, aiming to improve the problem of "relatively limited processing of circuit boards" mentioned in the prior art.

[0027] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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 of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0028] Refer to Figure 1 , Figure 2 , an embodiment provided by the present utility model: a visual positioning device for punching circuit boards, including a workbench 1. A frame 6 is fixedly connected to the left side of the workbench 1. A processing mechanism 9 is arranged inside the workbench 1. The processing mechanism 9 is used for clamping and rotating the circuit board to improve the processing efficiency of the circuit board. The processing mechanism 9 includes a circular sleeve 92. The circular sleeve 92 penetrates and is rotatably connected to the right wall of the workbench 1. A screw 96 is threadedly connected to the inner wall of the circular sleeve 92. When the screw 96 rotates, it will move left and right inside the circular sleeve 92. A square frame 2 is fixedly connected to the left side of the circular sleeve 92. The square frame 2 is used to assist in clamping the circuit board. A clamping block 91 for clamping the circuit board is rotatably connected to the left side of the screw 96. A material discharging assembly 3 for facilitating the sliding of the chips generated during the processing of the circuit board is arranged at the bottom end of the frame 6.

[0029] Refer to Figure 2, the clamping block 91 is slidably connected to the inner wall of the square box 2. Since the screw rod 96 is rotatably connected to the right side of the clamping block 91, when the screw rod 96 moves, it will not drive the clamping block 91 to rotate, and the clamping block 91 will only slide horizontally on the inner wall of the square box 2. The processing mechanism 9 further includes a T-shaped rod 95. The T-shaped rod 95 penetrates and is slidably connected to the rear surface of the circular sleeve 92. The T-shaped rod 95 and the circular sleeve 92 are elastically connected by a spring 94. The spring 94 plays a role in supporting and connecting the T-shaped rod 95 and the circular sleeve 92, and the reverse force of the spring 94 assists the T-shaped rod 95 to reset so that the limiting rod 93 slides into the rectangular groove 98 to limit the circular sleeve 92. One end of the spring 94 is fixedly connected to the front surface of the T-shaped rod 95, and the other end of the spring 94 is fixedly connected to the rear surface of the circular sleeve 92. A limiting rod 93 is fixedly connected to the left side of the T-shaped rod 95.

[0030] Refer to Figure 2 - Figure 4 , an annular groove 97 is opened on the right side of the workbench 1, and a rectangular groove 98 is opened on the outer side of the right side of the workbench 1 near the annular groove 97. The limiting rod 93 is adapted to the rectangular groove 98 and the annular groove 97. A placement groove 910 is opened on the inner wall of the square box 2, and a rubber pad 99 is fixedly connected to the inner wall of the placement groove 910. The rubber pad 99 is made of rubber and can be compressed. Its compressible property plays a buffering role in the circuit board during processing. A support ring 4 is fixedly connected to the top of the workbench 1. The support ring 4 is used to support the circular sleeve 92. The circular sleeve 92 is fixedly connected to the inner wall of the support ring 4. A plurality of placement shells 7 are arranged on the top of the workbench 1. The placement shells 7 can be used to place some processing tools.

[0031] Refer to Figure 1 , the blanking component 3 includes a blanking plate 31. The blanking plate 31 is inclined so that the chips generated during the processing of the circuit board can fall through the inclined surface. The blanking plate 31 is fixedly connected to the bottom end of the frame 6. A plurality of blanking grooves 32 are opened at the top end of the blanking plate 32. The blanking grooves 32 increase the blanking speed of the chips.

[0032] Working principle: When in use, first check whether each part of the device can operate normally. When the circuit board needs to be processed, first clamp one end of the circuit board in the placement groove 910 in the square box 2 and make the circuit board parallel. Then rotate the screw rod 96. Since the screw rod 96 is threadedly connected to the inner wall of the circular sleeve 92, the screw rod 96 is rotatably connected to the right side of the clamping block 91, and the clamping block 91 is slidably connected to the inner wall of the square box 2. So when the screw rod 96 rotates, the clamping block 91 will only move horizontally. Rotate the screw rod 96 to make the clamping block 91 move leftward to clamp the other end of the circuit board. And when the clamping block 91 squeezes the circuit board, the rubber pad 99 provided can play a buffering role on the edge of the circuit board. At this time, the drilling work can be started;

[0033] When it is necessary to adjust the processing angle of the circuit board, first hold the T-shaped rod 95 by hand and press it. The T-shaped rod 95 will move backward under pressure to compress the spring 94. And when the T-shaped rod 95 moves, it will drive the limit rod 93 to move together, making it slide out of the rectangular groove 98 and into the annular groove 97. At this time, the round sleeve 92 can be rotated, and the round sleeve 92 drives the square frame 2 to move together, so that the processing angle of the circuit board can be adjusted. When the angle adjustment is completed, slowly release the T-shaped rod 95. At this time, the reverse acting force of the spring 94 causes the T-shaped rod 95 to reset. The T-shaped rod 95 drives the limit rod 93 to reset, making it continue to slide into the rectangular groove 98 to limit the round sleeve 92, ensuring the stability of the circuit board processing;

[0034] In addition, the debris generated during work will slide downward through the blanking plate 31 in cooperation with the blanking groove 32, which is convenient for later collection.

[0035] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
