[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 The utility model provides an embodiment: an anti-deformation circuit board punching device includes a processing plate 1, the processing plate 1 is square in shape, the rear end of the processing plate 1 is fixedly connected with a bracket 2, the shape of the bracket 2 is an inverted L-shape, and the gravity of the lower end of the bracket 2 is heavier. By setting the gravity of the lower end of the bracket 2, it is ensured that the bracket 2 is not easy to deviate during use, the bottom end of the bracket 2 is fixedly connected with an electric telescopic rod 3, the bottom end of the electric telescopic rod 3 is fixedly connected with a motor 4, the bottom end of the motor 4 is fixedly connected with a mounting block 5, the shape of the mounting block 5 is cylindrical, and the bottom end of the mounting block 5 is fixedly connected with a drill bit 8.

[0032] Reference Figure 1 and Figure 3 An auxiliary component 6 is arranged inside the mounting block 5, and the auxiliary component 6 includes a slide groove 61. The slide groove 61 is opened on the inner wall of the mounting block 5 inside the drill bit 8. The inner wall of the slide groove 61 is slidably connected with an extrusion block 62. By setting the position of the slide groove 61, it is ensured that the extrusion block 62 can just contact the circuit board when the drill bit 8 is drilling. The drill bit 8 is in the shape of a ring. Through the ring setting, it is ensured that the powdery waste generated by drilling is less. The shape of the extrusion block 62 is a cylinder, and the diameter of the extrusion block 62 is smaller than the diameter of the drill bit 8. The top of the extrusion block 62 is elastically connected to the inner wall of the slide groove 61 by a spring 63. One end of the spring 63 is fixedly connected to the top of the extrusion block 62, and the other end of the spring 63 is fixedly connected to the inner wall of the slide groove 61.

[0033] Reference Figure 1 , Figure 2 and Figure 4 A fixing assembly 7 is provided at the top of the processing board 1, and the fixing assembly 7 includes a sliding frame 71. The bottom end of the sliding frame 71 is fixedly connected to the top of the processing board 1. The outer wall of the sliding frame 71 is slidably connected with a sliding rod 72. The distance between the top of the sliding frame 71 and the bottom end of the middle of the sliding rod 72 and the top of the processing board 1 is greater than the thickness of the circuit board. By setting the thickness, it is ensured that the sliding frame 71 and the sliding rod 72 will not contact the circuit board during the movement. The left and right ends of the sliding rod 72 are respectively provided with blocks with a shape similar to a concave shape. By setting the blocks, the stability of the installation of the sliding rod 72 is ensured, and the position of the sliding rod 72 is prevented from being offset.

[0034] Reference Figure 1 , Figure 2 and Figure 4The top of the sliding rod 72 is slidably connected to the sliding frame 71 through a block, and the top of the sliding rod 72 is slidably connected to the control block 73. The inner wall of the control block 73 is provided with a slideway 74. The shape of the slideway 74 is a rectangular parallelepiped. The inner wall of the slideway 74 is slidably connected to a slider 75. The inner wall of the slider 75 is penetrated and threadedly connected with a screw 76. The inner wall of the slider 75 is provided with a thread groove matching the screw 76. The outer wall of the screw 76 is penetrated and rotatably connected to the top of the control block 73. The end of the slider 75 close to the drill bit 8 is fixedly connected to a fixed block 77. The distance between the fixed block 77 and the processing plate 1 is equal to the distance between the slider 75 and the processing plate 1. The distance between block 75 and the bottom end of slideway 74 is consistent. By setting the distance, it is ensured that when slider 75 moves to the bottom end, fixed block 77 can just move to the position in contact with the surface of processing board 1, thereby ensuring that no matter how thick the circuit board to be fixed is, a good fixing effect can be obtained. The bottom end of fixed block 77 is fixedly connected with airbag 78. The material of airbag 78 is set to rubber, and airbag 78 is a spherical object with a hollow middle part and filled with gas. By setting the material of airbag 78, it is ensured that airbag 78 can undergo a certain degree of deformation and is not easy to damage other objects on the circuit board.

[0035] Working principle: When in use, the staff first places the position of the circuit board to be drilled at the bottom end of the drill bit 8 according to the position of the drill bit 8. After the placement is completed, the staff pushes the sliding rod 72 and the control block 73, so that the control block 73 is in the area near the position where the hole needs to be drilled.

[0036] When the position of the control block 73 is selected, the staff rotates the screw 76 to rotate the screw 76. At this time, since the slider 75 is restricted by the slide 74, the slider 75 rotates with the rotation of the screw 76, so the slider 75 slides downward. During the downward sliding process of the slider 75, the fixed block 77 slides downward with the slider 75.

[0037] When sliding to the position contacting the circuit board, the airbag 78 is deformed, so that the airbag 78 is close to the circuit board, so that the position outside the punching area has both the squeezing force of the fixed block 77 and the protection of the airbag 78, so the circuit board is not easily deformed at this time.

[0038] Then, the staff starts the power supply of the equipment, so that the electric telescopic rod 3 pushes the motor 4 to move downward, and the motor 4 also drives the mounting block 5 to rotate during the downward movement, and the mounting block 5 drives the spring 63 and the extrusion block 62 to move downward during the downward movement.

[0039] Since the squeezing block 62 is subject to the elastic force of the spring 63, when the drill bit 8 is not in contact with the circuit board, the bottom end of the squeezing block 62 has already been in contact with the circuit board and provides a downward force to the circuit board, thereby fixing the position of the circuit board inside the punching area.

[0040] During the drilling process, since the drill bit 8 moves downward, the extrusion block 62 can also enter the interior of the slide groove 61 under the effect of extrusion, thereby ensuring that the drill bit 8 can rotate downward normally and ensure that the drilling operation is successfully carried out.

[0041] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
