Technical Field
[0001] This utility model relates to the technical field of circuit board processing equipment, specifically to a device for processing stepped plug-in hole printed circuit boards. Background Technology
[0002] A stepped-hole printed circuit board (PCB) is a PCB containing stepped-hole mounting holes. The main characteristic of stepped-hole technology is its use for mounting components, improving product integration, or achieving signal shielding. Currently, the main method for manufacturing stepped-hole PCBs involves drilling holes in the core board layer containing the stepped-hole, laminating it with an adhesive laminate, and then drilling again to expose the bottom pattern of the hole. Therefore, processing stepped-hole PCBs requires drilling the circuit board. The current method typically involves first fixing the PCB in place and then drilling the holes using a drilling fixture. However, this method is cumbersome, requiring frequent replacement of the PCB after drilling, which consumes a lot of time and affects the processing efficiency of the PCB. Therefore, this invention proposes a stepped-hole PCB processing device to solve this problem. Utility Model Content

During use, the lifting module controls the positioning frames to move upwards, and then the corresponding circuit board is processed using a drilling fixture. After processing, an electric push rod controls the telescopic frame plate to move, thereby bringing out the corresponding positioning frame, achieving automatic unloading of the circuit board. Furthermore, it can continuously and uninterruptedly perform drilling processing on printed circuit boards, solving the problem of low working efficiency in current devices.

[0013] (III) Beneficial Effects
[0014] Compared with the prior art, the present invention provides a processing device for printed circuit boards with stepped insertion holes, which has the following advantages:
[0015] This invention utilizes a base plate to fix a limiting frame and a lifting module. Positioning frames are sequentially arranged inside the limiting frame to clamp and fix the printed circuit board. Multiple positioning frames are arranged sequentially inside the limiting frame to achieve continuous feeding of the printed circuit board. A support plate is installed at the top of the lifting module, with its upper surface abutting against one of the bottom positioning frames, thus supporting the upward movement of the positioning frame.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0022] Example
[0023] like Figure 1 , Figure 2 and Figure 3 As shown in the figure, an embodiment of the present invention provides a stepped insertion hole printed circuit board processing device, including a base plate 1, and further including: a limiting frame 2, which is fixed to the base plate 1 by a support base, the limiting frame 2 including a frame body 201 fixedly connected to the support base, and a limiting groove 205 is formed on the upper part of the frame body 201, and a telescopic frame plate 203 is adapted to the limiting groove 205; a positioning frame 5, which is sequentially arranged on the inner side of the frame body 201 to realize the clamping and feeding of the circuit board, the positioning frame 5 including a rectangular frame body 501 adapted to the inner wall of the frame body 201, and a protrusion 502 integrally formed on the inner wall of the rectangular frame body 501, and the circuit board is arranged on the protrusion 502; a support plate 6, which is adapted to the inner bottom of the frame body 201, and the upper surface of the support plate 6 abuts against a positioning frame 5 at the bottom to realize the support movement of the positioning frame 5.
[0024] It should be noted that the base plate 1 is the bottom support part of the device. The installation of the limiting frame 2 is achieved by fixing the support base on the base plate 1. The main body of the limiting frame 2 is the frame body 201. A limiting groove 205 is opened in the upper part of the frame body 201, and a telescopic frame plate 203 is set in the limiting groove 205. The telescopic frame plate 203 can extend and retract along the limiting groove 205, thereby bringing out the positioning frame 5 and the circuit board corresponding to the frame body 201, realizing the automatic unloading of the circuit board. When drilling the circuit board, The telescopic frame plate 203 is hidden in the limiting groove 205. Positioning frames 5 are arranged sequentially on the inner side of the frame 201. The positioning frames 5 are used for clamping and positioning the circuit board and for feeding the circuit board upward. When the positioning frame 5 moves to the inner side of the telescopic frame plate 203, the circuit board on the positioning frame 5 can be drilled. By setting a support plate 6 at the bottom inner side of the frame 201, the positioning frame 5 is supported and driven. This method can continuously drill the circuit board without interruption, which is highly efficient.
[0025] like Figure 3 As shown, in some embodiments, a stop block 504 is rotatably connected to a groove 503 on the upper surface of the rectangular frame body 501. When the stop block 504 rotates, it clamps and positions the circuit board.
[0026] It should be noted that when using the circuit board, place it on the protrusion 502, and then rotate the stop block 504 so that one side of the stop block 504 abuts against the upper surface of the circuit board, thereby clamping and fixing the circuit board. This method facilitates the disassembly and assembly of the circuit board and is convenient.
[0027] like Figure 2 As shown, in some embodiments, an extension plate 202 protrudes from one side of the frame 201, a limiting groove 205 extends to the outside of the extension plate 202, and an electric push rod 204 is installed on one side of the frame 201, and the output shaft of the electric push rod 204 is connected and fixed to the telescopic frame plate 203.
[0028] It should be noted that by setting an extension plate 202 on one side of the frame 201, the transmission stability of the telescopic frame plate 203 can be guaranteed. After the drilling of the circuit board on the positioning frame 5 inside the telescopic frame plate 203 is completed, the electric push rod 204 can be driven to work, so that the telescopic frame plate 203 moves along the limiting groove 205, and then the positioning frame 5 and the circuit board inside it are brought out, realizing the automatic unloading of the circuit board and the corresponding positioning frame 5.
[0029] like Figure 1 and Figure 4As shown, in some embodiments, a lifting module 7 is also included. The lifting module 7 includes: a protective frame 701, fixed to the upper surface of the base plate 1; a bidirectional lead screw 702, rotatably connected to the protective frame 701; two sliders 704, which are symmetrically threaded to the bidirectional lead screw 702; and a lifting plate 707, fixedly connected to the lower surface of the support plate 6, with support arms 703 rotatably connected to the corresponding sliders 704 on both sides of the lifting plate 707.
[0030] It should be noted that the lifting module 7 can control the lifting of the support plate 6. The lifting module 7 mainly consists of a protective frame 701, a two-way lead screw 702, a support arm 703, a slider 704, and a lifting plate 707. When the two-way lead screw 702 rotates, the two sliders 704 can move towards each other, causing the support arm 703 to fold. Then, the support arm 703 supports the lifting plate 707 to move upward, thereby realizing the movement control of the support plate 6.
[0031] like Figure 4 As shown, in some embodiments, a motor 705 is installed on one side of the protective frame 701, the output shaft of the motor 705 is connected and fixed to the bidirectional lead screw 702, and a limit rod 706 is fixedly connected to the protective frame 701. The slider 704 has a limit hole that is adapted to the limit rod 706 at the corresponding limit rod 706.
[0032] It should be noted that the motor 705 is a servo type with high precision, which can stably and accurately control the rotation of the bidirectional lead screw 702. By setting the limit rod 706, the limit rod 706 can realize the extension and retraction limit function of the slider 704, so as to achieve the stable extension and retraction of the slider 704.
[0033] like Figure 1 As shown, in some embodiments, a frame 3 is fixedly connected to the base plate 1, and a punching fixture 4 is installed on the frame 3.
[0034] It should be noted that the drilling tool 4 can perform drilling on circuit boards. Its usage and principle are known existing technologies and will not be elaborated here.
[0035] The working principle and usage steps of this utility model are as follows: Before use, the printed circuit board needs to be assembled into the corresponding positioning frame 5. During assembly, the circuit board is placed on the protrusion 502 of the rectangular frame body 501. Then, the stop block 504 is rotated so that the lower surface of the stop block 504 abuts against the upper surface of the circuit board, thereby assembling and positioning the circuit board. Then, the positioning frame 5 with the assembled circuit board is placed sequentially on the support plate 6 in the limiting frame 2 to achieve one-time feeding of the circuit board. Then, the motor 705 in the lifting module 7 is driven to work, driving the bidirectional lead screw 702 to rotate, so that the two sliders 704 move inward along the limiting rod 706 at the same time. The support arm 703 is folded, enabling the lifting plate 707 to move upward, thereby controlling the support of the support plate 6. The positioning frame 5 moves upward, and the uppermost positioning frame 5 is positioned inside the telescopic frame plate 203. Then, the circuit board on the positioning frame 5 is drilled using the drilling fixture 4. After drilling, the electric push rod 204 operates, causing the telescopic frame plate 203 to move along the limiting groove 205, bringing out the positioning frame 5 and the corresponding circuit board. The operator can then remove it. Afterward, the electric push rod 204 controls the telescopic frame plate 203 to reset, and the lifting module 7 controls the support plate 6 and positioning frame 5 to move upward, enabling continuous processing of the circuit board.
[0036] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
