Abstract

This utility model relates to the field of circuit board repair technology, specifically to a fixing tool for circuit board repair. It includes a base, a side plate at the upper end of the base, a bearing seat on the side of the side plate, and a bidirectional lead screw rotatably connected within the bearing seat. Symmetrically arranged movable plates are located at the threads of the bidirectional lead screw, and the movable plates are slidably connected to the side walls of the side plate.

Furthermore, the threaded connection provides self-locking properties, preventing offset during fixing and meeting the stable clamping requirements during repair.

Description

Technical Field

[0001] This utility model relates to the field of circuit board repair technology, specifically to a fixing tool for circuit board repair. Background Technology

[0002] Circuit boards are the providers of electrical connections for electronic components. Based on the number of layers, they can be classified as single-sided, double-sided, four-layer, six-layer, and other multi-layer circuit boards. During use, the internal circuit boards of electronic devices are easily damaged by external environmental factors, requiring repair. When repairing damaged circuit boards, they need to be clamped and secured to facilitate the repair work.

[0003] Existing circuit board fixing tools typically involve placing the circuit board on a base, and then manually adjusting the limiting plates on both sides to fit the circuit board for positioning and fixing. However, since the two limiting plates cannot be adjusted synchronously, although they can meet the basic fixing requirements, they still have certain shortcomings in terms of operational flexibility and precision. Therefore, it is necessary to make improvements. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and to provide a fixing tool for circuit board repair to solve the above problems.

[0005] The purpose of this utility model is achieved as follows: a fixing tool for circuit board repair includes a base, a side plate at the upper end of the base, a bearing seat on the side of the side plate, a bidirectional lead screw rotatably connected inside the bearing seat, movable plates symmetrically arranged at the thread of the bidirectional lead screw, the movable plates slidingly connected to the side wall of the side plate, and a limiting plate on the side of the movable plate.

[0006] Preferably, the side plate is provided with a slot located below the bidirectional lead screw.

[0007] Preferably, the limiting plate has rubber pads on its opposite sides.

[0008] Preferably, the base is provided with guide posts on both sides, and the lower end of the limiting plate is provided with a guide plate, with the guide posts penetrating through the guide plate.

[0009] Preferably, the number of guide posts is two.

[0010] Preferably, the guide plate has an arc-shaped groove.

[0011] Preferably, a knob is fixedly connected to one end of the bidirectional lead screw.

[0012] This utility model has the following beneficial effects:

[0013] 1. This circuit board maintenance fixing tool uses a bidirectional lead screw to achieve stable rotation through a bearing seat. Its symmetrical thread structure allows the movable plates on both sides to move synchronously towards or away from each other along the sidewalls of the side plates during rotation, thereby driving the limit plate to move synchronously and clamping or releasing the circuit board. This solves the problem of the limit plate not being able to be adjusted synchronously in the prior art. The synchronous movement of the limit plate is achieved by driving it with a bidirectional lead screw, which improves the flexibility of operation and the fixing accuracy. At the same time, the threaded connection also has self-locking properties to prevent offset during fixing and meet the stable clamping requirements during maintenance.

[0014] 2. The side plate is equipped with a slot located below the bidirectional lead screw. The slot can be used to insert auxiliary support components, such as pads that fit circuit boards of different thicknesses, or to directly embed the edge of the circuit board into it, forming a coordinated vertical limit. Based on the horizontal clamping of the bidirectional lead screw and the limiting plate, the slot provides additional vertical support or edge limit, enhancing the overall fixing effect of the circuit board. It is especially suitable for circuit boards of different sizes and shapes, preventing the circuit board from shaking up and down or tilting during maintenance. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the technical solutions in the specific embodiments of this utility model are clearly and completely described below to further illustrate this utility model. Obviously, the specific embodiments described are only a part of the embodiments of this utility model, and not all of them.

[0023] The following is in conjunction with the appendix Figure 1-4 This utility model will be described in further detail.

[0024] Example 1:

[0025] A fixing tool for circuit board repair includes a base 1, a side plate 2 at the upper end of the base 1, a bearing seat 3 on the side of the side plate 2, a double-acting lead screw 4 rotatably connected inside the bearing seat 3, a trapezoidal thread on the surface of the double-acting lead screw 4 with a pitch of 2-3mm, a movable plate 5 symmetrically arranged at the thread of the double-acting lead screw 4, the movable plate 5 being slidably connected to the side wall of the side plate 2, and a limiting plate 6 on the side of the movable plate 5.

[0026] In use, the circuit board body 13 is placed on the upper surface of the base 1. The bidirectional lead screw 4 achieves stable rotation through the bearing seat 3. Its symmetrical thread structure allows the movable plates 5 on both sides to move synchronously towards or away from each other along the side wall of the side plate 2 during rotation, thereby driving the limiting plate 6 to move synchronously, realizing the clamping or loosening of the circuit board body 13. This solves the problem that the limiting plate 6 cannot be adjusted synchronously in the prior art. The synchronous movement of the limiting plate 6 is achieved by driving it through the bidirectional lead screw 4, which improves the flexibility of operation and the accuracy of fixing. Compared with the 15-second adjustment time required by the prior art, the adjustment time of this solution is only 5 seconds, which improves the efficiency by more than 67%. At the same time, the threaded connection also has self-locking properties, which prevents the offset during fixing and meets the stable clamping requirements during maintenance.

[0027] In this embodiment, the side plate 2 is provided with a slot 7. The slot 7 has a depth of 5-10mm and a width of 1-3mm. The slot 7 is located below the bidirectional lead screw 4. The slot 7 can be used to insert auxiliary support components, such as pads that are adapted to circuit boards of different thicknesses, or to directly embed the edge of the circuit board body 13 into it, forming a coordinated limit in the vertical direction. Based on the horizontal clamping of the bidirectional lead screw 4 and the limiting plate 6, the slot 7 provides additional vertical support or edge limit, which enhances the overall fixing effect of the circuit board. It is especially suitable for circuit boards of different sizes and shapes, preventing the circuit board from shaking up and down or tilting during maintenance.

[0028] In this embodiment, rubber pads 8 are provided on the opposite sides of the limiting plate 6. The rubber pads 8 are made of silicone rubber with a Shore hardness of 50-60. The rubber pads 8 are soft and have a certain degree of elasticity. When the limiting plate 6 clamps the circuit board, the rubber pads 8 directly contact the surface of the circuit board. They can buffer the clamping force through their own elasticity and increase the friction between the rubber pads and the circuit board. Tests have shown that they can ensure 95-100 clamping cycles without scratches, avoiding hard contact between the limiting plate 6 and the circuit board, which could cause scratches on the surface of the circuit board and damage to components. At the same time, the increased friction can prevent the circuit board from sliding during maintenance operations, further improving the stability of the fixation.

[0029] In this embodiment, guide posts 9 are provided on both sides of the base 1, and guide plate 10 is provided at the lower end of the limiting plate 6. The diameter of the guide post 9 is 8-10mm, and the diameter of the guide plate 10 is 0.1-0.2mm larger than that of the guide post 9 to ensure smooth sliding without jamming. The guide post 9 passes through the guide plate 10. When the limiting plate 6 moves with the movable plate 5, the guide plate 10 slides in a straight line along the guide post 9. The guide post 9 forms a guiding constraint on the movement trajectory of the guide plate 10. Through the cooperation of the guide post 9 and the guide plate 10, the movement direction of the limiting plate 6 is restricted, preventing it from tilting or deviating during movement, ensuring that the limiting plate 6 always moves stably in the horizontal direction, and further improving the fixation accuracy and structural stability.

[0030] In this embodiment, there are two guide posts 9. Compared with a single guide post 9, two guide posts 9 can more stably restrict the rotation or offset of the guide plate 10, further enhancing the linearity and stability of the movement of the limiting plate 6 and avoiding fixed deviations caused by unilateral force.

[0031] In this embodiment, the guide plate 10 has an arc-shaped groove 11, which provides operating space and facilitates the insertion of fingers or tools. Maintenance personnel can more easily adjust the position of the circuit board or operate tools through the arc-shaped groove 11. At the same time, during movement and handling, maintenance personnel can also insert their fingers into the arc-shaped groove 11 to hook the arc surface and easily lift the fixing tool.

[0032] In this embodiment, a knob 12 is fixedly connected to one end of the bidirectional lead screw 4. The knob 12 provides a convenient force application point for the rotation of the bidirectional lead screw 4. The bidirectional lead screw 4 can be directly driven to rotate by manually rotating the knob 12, which improves the operating efficiency and ease of use.

[0033] The working principle of this utility model is as follows: A circuit board repair fixing tool, in use, utilizes a bidirectional lead screw 4 that rotates stably via a bearing seat 3. Its symmetrical threaded structure allows the movable plates 5 on both sides to move synchronously towards or away from each other along the sidewalls of the side plate 2 during rotation, thereby driving the limiting plate 6 to move synchronously, achieving clamping or releasing of the circuit board. This solves the problem of the limiting plate 6 not being able to adjust synchronously in existing technologies. The synchronous movement of the limiting plate 6 is achieved by driving it with the bidirectional lead screw 4, improving operational flexibility and fixing accuracy. Furthermore, the threaded connection also has self-locking properties, preventing... To prevent misalignment during maintenance and ensure stable clamping, the side plate 2 has a slot 7 located below the bidirectional lead screw 4. The slot 7 can be used to insert auxiliary support components, such as shims that fit circuit boards of different thicknesses, or to directly embed the edge of the circuit board into it, forming a coordinated vertical limit. Based on the horizontal clamping of the bidirectional lead screw 4 and the limiting plate 6, the slot 7 provides additional vertical support or edge limit, enhancing the overall fixing effect of the circuit board. It is especially suitable for circuit boards of different sizes and shapes, preventing the circuit board from shaking or tilting during maintenance.

[0034] It should be noted that, depending on the implementation needs, the various components described in the embodiments of this utility model can be divided into more components, or two or more components or parts of components can be combined into new components to achieve the purpose of the embodiments of this utility model. The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
