Description

Technical Field

[0001] This utility model relates to the field of circuit board processing technology, specifically to a circuit board binding wire fixing device. Background Technology

[0002] PCBA wire bonding refers to a process in PCBA (Printed Circuit Board Assembly) where metal wires (such as aluminum or gold wires) are used to connect chips to pads on the PCB. This process is called "bonding" or "wire bonding," and the specific steps involve using a wire bonder to solder metal wires between the chip's pins and the corresponding pads on the PCB, thereby achieving an electrical connection.

[0003] A high-voltage sensor in the prior art has a PCBA circuit board and a metal hexagonal head (such as...). Figure 1 When binding wires between the PCBA circuit boards (as shown), the PCBA circuit board is placed on the hexagonal head. Due to the lack of fixing parts, the PCBA circuit board is easy to move on the hexagonal head, making it difficult to solder the binding wires. In addition, it is generally placed manually, and the positioning position is determined by the person. The placement time is relatively slow, and the positioning is inaccurate and easy to shift.

[0004] In view of this, there is an urgent need for a circuit board binding wire fixing device to solve the above problems. Utility Model Content

[0005] To address the problems existing in the prior art, this utility model solves the problem using the following technical structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A circuit board binding wire fixing device includes: a base, a mounting base, and a positioning component; the base is provided with a limiting hole;

[0008] Guide posts are provided on both sides of the mounting base, and mounting grooves are provided on both sides of the base. The two guide posts are slidably disposed in the mounting grooves, and the mounting base is disposed in the direction of the opening of the limiting hole. When the guide posts slide in the mounting grooves, the mounting base moves closer to or further away from the limiting hole.

[0009] The positioning component includes a positioning block and a limiting pin. The positioning block is disposed on the mounting base, and the limiting pin is disposed on the side of the positioning block near the base.

[0010] Each of the mounting slots is provided with a limiting shaft, and the guide post is provided with a straight limiting groove, through which the limiting shaft passes.

[0011] The mounting groove includes a guide groove and a steering groove. The extension direction of the guide groove is consistent with the opening direction of the limiting hole. The steering groove is located on the side of the guide groove near the opening of the limiting hole. The limiting shaft is located at the steering groove.

[0012] The end of the guide post furthest from the mounting base is the guide end. When the guide end is located in the guide groove, the guide groove restricts the guide post to make linear movements; when the guide end is located in the steering groove, the limiting shaft restricts the guide post to make steering movements.

[0013] The mounting groove also includes a limiting plane disposed on the side of the steering groove away from the guide groove. The limiting plane is inclined and faces the limiting pin.

[0014] The positioning block is provided with a plurality of limiting pins.

[0015] The positioning block is provided with a plurality of positioning holes, and the limiting pin is inserted into one of the positioning holes.

[0016] The limiting holes are provided in a plurality of them, and the plurality of limiting holes are distributed in a straight line from one of the mounting slots to another mounting slot;

[0017] The positioning components are provided in multiple ways, and each of the multiple positioning components corresponds to one of the multiple limiting holes.

[0018] The positioning block is slidably mounted on the mounting base.

[0019] The sliding direction of the positioning block is perpendicular to the distribution direction of the positioning components.

[0020] An extraction groove is provided on the circumferential side of the opening of the limiting hole.

[0021] The above-described structure of this utility model can achieve the following beneficial effects:

[0022] In use, first adjust the mounting base to a position away from the opening of the limiting hole, insert the hexagonal head bolt into the limiting hole, place the circuit board on the hexagonal head bolt, and then bring the mounting base close to the limiting hole until the end of the limiting pin is inserted into the hole or notch of the circuit board, thereby limiting the horizontal position of the circuit board and preventing the circuit board from moving relative to the hexagonal head bolt when binding wire. Simply adjust the position of the limiting pin according to the position of the hole or notch on the circuit board to quickly fix the relative position of the circuit board and the hexagonal head bolt, improving the convenience and efficiency of wire binding.

[0029] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] It should be noted that the terms "comprising" and "having" and any variations thereof in the specification, claims and accompanying drawings of this utility model are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such processes, methods, products or devices.

[0031] The following is in conjunction with the appendix Figures 1-5 This application will be described in further detail.

[0032] like Figures 1-3 As shown, a circuit board binding wire fixing device includes: a base 1, a mounting base 2, and a positioning component; the base 1 is provided with a limiting hole 11, the cavity shape of the limiting hole 11 is adapted to the workpiece to be fixed, and in this embodiment, the limiting hole 11 is hexagonal prism-shaped to limit the hexagonal head bolt 7.

[0033] Guide posts 4 are provided on both sides of the mounting base 2, and mounting grooves are provided on both sides of the base 1. The two guide posts 4 are slidably disposed in the mounting grooves, and the mounting base 2 is disposed in the direction of the opening of the limiting hole 11. When the guide posts 4 slide in the mounting grooves, the mounting base 2 moves closer to or further away from the limiting hole 11.

[0034] The positioning component includes a positioning block 3 and a limiting pin 6. The positioning block 3 is mounted on the mounting base 2, and the limiting pin 6 is located on the side of the positioning block 3 near the base 1.

[0035] Based on the above structure, during use, first adjust the mounting base 2 to a position away from the opening of the limiting hole 11, insert the hexagonal head bolt 7 into the limiting hole 11, place the circuit board 8 on the hexagonal head bolt 7, and then bring the mounting base 2 close to the limiting hole 11 until the end of the limiting pin 6 is inserted into the hole or notch of the circuit board 8, thereby limiting the horizontal position of the circuit board 8 and preventing the circuit board 8 from moving relative to the hexagonal head bolt 7 during wire binding. By simply adjusting the position of the limiting pin 6 according to the position of the hole or notch on the circuit board 8, the relative position of the circuit board 8 and the hexagonal head bolt 7 can be quickly fixed, improving the convenience and efficiency of wire binding.

[0036] like Figure 4 and Figure 5 As shown, each mounting groove is equipped with a limiting shaft 5, and the guide post 4 is equipped with a straight limiting groove 41. The limiting shaft 5 is horizontally inserted into the limiting groove 41, so that the limiting groove 41 and the limiting shaft 5 can limit the movement range of the guide post 4.

[0037] like Figure 4 and Figure 5 As shown, the mounting groove includes a guide groove 12 and a steering groove 13. The extension direction of the guide groove 12 is consistent with the opening direction of the limiting hole 11. The steering groove 13 is located on the side of the guide groove 12 near the opening of the limiting hole 11, and the limiting shaft 5 is located in the steering groove 13. The end of the guide post 4 away from the mounting base 2 is the guide end. When the guide end is located in the guide groove 12, the guide groove 12 restricts the guide post 4 from linear movement. When the guide end is located in the steering groove 13, the limiting shaft 5 restricts the guide post 4 from steering movement. Thus, when the guide post 4 slides in the guide groove 12... It can only perform linear motion, that is, to make the mounting base 2 move up and down, and adjust the height of the mounting base 2. When the guide end (the bottom end of the guide post 4) enters the steering groove 13, the limiting shaft 5 is exactly placed at the bottom of the limiting groove 41, and the width of the steering groove 13 is greater than the width of the guide groove 12, so that the guide post 4 can rotate around the limiting shaft 5 as the axis, causing the mounting base 2 to swing to one side, away from the opening of the limiting hole 11 (that is to say, the mounting base 2 will not block the position directly opposite the opening of the limiting hole 11), so as to avoid interfering with the placement and removal of the hexagonal head bolt 7 and the circuit board 8.

[0038] like Figure 4and Figure 5 As shown, the mounting groove also includes a limiting plane 14 disposed on the side of the steering groove 13 away from the guide groove 12. The limiting plane 14 is inclined and faces the limiting pin 6. The rotation angle of the guide pin 4 is limited by the limiting plane 14. When the guide pin 4 rotates and fits against the limiting plane 14, the guide pin 4 cannot continue to rotate, thus limiting the guide pin 4.

[0039] like Figure 2 and Figure 3 As shown, in order to improve the stability of the positioning of the circuit board 8, multiple limiting pins 6 are provided on the positioning block 3. The circuit board 8 is effectively positioned by inserting multiple limiting pins 6 into the holes or notches of the circuit board 8. The positioning block 3 is provided with multiple positioning holes, and the limiting pins 6 are inserted into one of the positioning holes. For different circuit boards 8, the limiting pins 6 are set in different positioning holes to adapt to the positioning of different circuit boards 8.

[0040] like Figure 2 and Figure 3 As shown, in order to improve positioning efficiency and batch processing, multiple limiting holes 11 are provided, and the multiple limiting holes 11 are distributed in a straight line from one mounting slot to another mounting slot; multiple positioning components are provided, and the multiple positioning components correspond one-to-one with the multiple limiting holes 11. The workpieces at the multiple limiting holes 11 are positioned by the multiple positioning components to achieve the purpose of batch processing.

[0041] Further optimization involves slidably mounting the positioning block 3 on the mounting base 2, with the position of the positioning block 3 locked by bolts and other components. During use, the positioning block 3 can slide on the mounting base 2 according to the position of the holes or notches on different circuit boards, adjusting the position of the limiting pin 6 to improve adaptability. Moreover, the sliding direction of the positioning block 3 is preferably perpendicular to the distribution direction of several positioning components, increasing the sliding range of the positioning block 3 and the adjustment range of the limiting pin 6.

[0042] like Figure 2 and Figure 3 As shown, in order to facilitate the removal of the product, an extraction groove 15 is provided on the circumferential side of the opening of the limiting hole 11. Preferably, two extraction grooves 15 are provided and are positioned opposite each other on the opposite side of the opening of the limiting hole 11. This allows the circumferential direction of the hexagonal head bolt 7 to be controlled through the extraction grooves 15 when the product is taken out, further improving the convenience of use.

[0043] In summary, during use, first adjust the mounting base 2 to a position away from the opening of the limiting hole 11, insert the hexagonal head bolt 7 into the limiting hole 11, place the circuit board 8 on the hexagonal head bolt 7, and then bring the mounting base 2 close to the limiting hole 11 until the end of the limiting pin 6 is inserted into the hole or notch of the circuit board 8, thereby limiting the horizontal position of the circuit board 8 and preventing the circuit board 8 from moving relative to the hexagonal head bolt 7 during wire binding. Simply adjust the position of the limiting pin 6 according to the position of the hole or notch on the circuit board 8 to quickly fix the relative position of the circuit board 8 and the hexagonal head bolt 7, thereby improving the convenience and efficiency of wire binding.

[0044] The above are merely preferred embodiments of this application, and the present invention is not limited to the above embodiments. It is understood that other improvements and variations that can be directly derived or conceived by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included within the protection scope of the present invention.
