Description

Technical Field

[0001] The present application relates to the technical field of disassembly and assembly of circuit boards of automobile parts, and in particular to a circuit board disassembly tool. Background Art

[0002] With the development of intelligent automobile technology, the components or functional modules installed on the car are gradually becoming integrated and miniaturized, such as automobile fuel tank cap or charging port door cover locking actuator, automobile air conditioning damper actuator, charging port door cover flip actuator and other functional modules. The size of the circuit board installed in the automobile functional module is also getting smaller and smaller, and the integrated circuits on the circuit board are becoming more and more complex. Especially in the process of line maintenance or debugging, it is often necessary to remove a circuit board or electronic component between the densely packed electronic components on the circuit board for replacement or repair; in the process of disassembling the circuit board or electronic component, it is necessary to ensure that other electronic components on the circuit board are not damaged, which requires that the circuit board must be well fixed or limited when disassembling. Currently, the most commonly used circuit board fixing tool is to use two clamps that can move horizontally relative to each other to clamp and position the two opposite side walls of the circuit board. However, the circuit board fixing tool with this structure is mostly suitable for circuit boards with larger areas. For circuit boards with smaller sizes, the clamping operation is very troublesome. Moreover, when squeezing and fixing the circuit board, if the clamping force is too large, it will cause damage to the circuit board. If the holding force is too small, it will easily cause the circuit board to fall off, which is very inconvenient to use. Utility Model Content

[0003] The technical problem to be solved by the present application is to overcome the defects of the above-mentioned related technologies and provide a circuit board disassembly tool that is not only suitable for disassembling circuit boards with smaller sizes, but also has very simple, convenient and fast fixing operations for the circuit boards.

[0004] The technical solution of the present application is to provide a circuit board disassembly tool having the following structure:

[0008] A driving assembly is connected to the base, and the driving assembly is respectively connected to the rotating shaft portion of each clamping assembly for driving the rotating shaft portion of the clamping assembly to rotate, so that the pressure head on the rotating shaft portion simultaneously rotates into the placement area to press the circuit board in the placement area, or simultaneously rotates out of the placement area to loosen the circuit board in the placement area.

[0009] In some embodiments, the driving assembly includes a driving gear and transmission gears respectively connected to the rotating shaft portion, the driving gear is rotatably connected to the base and / or the workbench, and the driving gear is respectively meshed with each of the transmission gears.

[0010] In some embodiments, a handle extending radially outward is connected to the driving gear; a support block is connected to the base, and a guide groove extending in a horizontal direction is provided on the support block, and the free end of the handle extends outward from the inside of the guide groove; when the handle moves to one end of the guide groove, the pressure head on the rotating shaft portion is in a position to loosen the circuit board, and when the handle moves to the other end of the guide groove, the pressure head on the rotating shaft portion is in a position to clamp the circuit board.

[0011] In some embodiments, there are three clamping components, and the three clamping components are distributed in a triangle.

[0012] In some embodiments, the working plane is partially recessed downward to form a receiving groove for receiving the circuit board, and the bottom center of the receiving groove forms the placement area.

[0013] In some embodiments, the plurality of clamping assemblies are disposed in the receiving groove, and the top of the pressing head of the clamping assembly does not extend out of the working plane.

[0017] In some embodiments, a plurality of support columns are connected between the workbench and the base, and the drive assembly is connected in the space between the workbench and the base.

[0018] In summary, compared with the related art, the circuit board disassembly tool of the present application has the following advantages: when disassembling the circuit board, the circuit board disassembly tool can place the circuit board to be disassembled in the placement area on the top of the workbench, and then drive the driving component to make the driving component drive the rotating shaft part of the clamping component to rotate, so that the pressure head on the rotating shaft part simultaneously rotates toward the placement area to press the circuit board in the placement area.

[0028] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See also Figure 1 to Figure 4 As shown; the embodiment of the present application discloses a circuit board disassembly tool, which is used to fix or limit the circuit board to be disassembled. The structure of the circuit board disassembly tool includes a base 1, a workbench 2, a drive component 3 and a plurality of clamping components 4, wherein the base 1 is placed or connected on the operating table, the workbench 2 is connected to the base 1, the workbench 2 is a flat plate structure, and the top of the workbench 2 has a horizontally arranged working plane 200, and the working plane 200 is provided with a placement area for placing the circuit board; the plurality of clamping components 4 are distributed along the circumference of the placement area, and the plurality of clamping components 4 are respectively arranged vertically and connected to each other in a self-rotatable manner. On the workbench 2, each clamping assembly 4 includes a rotating shaft portion 400 rotatably connected to the workbench 2 and a pressing head 401 located above the placement area and connected to the free end of the rotating shaft portion 400 and capable of rotating synchronously with the rotating shaft portion 400; the driving assembly 3 is connected to the base 1, and the driving assembly 3 is respectively connected to the rotating shaft portion 400 of each clamping assembly 4 for driving the rotating shaft portion 400 of the clamping assembly 4 to rotate, so that the pressing head 401 on the rotating shaft portion 400 simultaneously rotates toward the placement area to press the circuit board in the placement area, or simultaneously rotates out of the placement area to loosen the circuit board in the placement area.

[0030] For example, the number of the clamping assemblies 4 is at least three, and the three clamping assemblies 4 are distributed in a triangle, such as Figure 3In the distribution state shown, three clamping assemblies 4 are used to clamp two opposite sides and one end face of the circuit board respectively. The three clamping assemblies 4 form a three-point positioning of the circuit board, so that the clamped circuit board will not deviate and the clamping stability is good.

[0031] In this embodiment, if Figure 1 and Figure 3 As shown, when the circuit board is disassembled, the circuit board to be disassembled can be placed horizontally in the placement area on the top of the workbench 2, and then the driving component 3 is driven to make the driving component 3 drive the rotating shaft portion 400 of the clamping component 4 to rotate, so that the pressure head 401 on the rotating shaft portion 400 is simultaneously rotated toward the placement area to press the circuit board in the placement area. At this time, the position of the circuit board is limited, and the technician can disassemble the circuit board or replace electronic components; when the circuit board is disassembled, the driving component 3 is driven again, so that the driving component 3 drives the rotating shaft portion 400 of the clamping component 4 to rotate in the opposite direction, so that the pressure head 401 on the rotating shaft portion 400 is simultaneously rotated out of the placement area to loosen the circuit board in the placement area. The circuit board disassembly tool is not only suitable for the disassembly of larger-sized circuit boards, but also suitable for the disassembly of smaller-sized circuit boards, and has a simple structure and is easy to operate. In addition, when the pressure heads 401 on the rotating shaft portion 400 are simultaneously rotated toward the placement area, the circuit board in the placement area can be fixed or pressed, so that only a small space needs to be reserved to meet the requirements for fixing the circuit board, and no squeezing damage will be caused to the circuit board. The driving component 3 can drive the pressure heads 401 of all the clamping components 4 to rotate and press the circuit board at the same time, so that the circuit board can be quickly fixed and the disassembly efficiency of the circuit board can be improved.

[0032] Furthermore, if Figure 1 , Figure 3 and Figure 4 As shown, in the embodiment of the present application, the pressure head 401 is welded and fixed to the upper end of the rotating shaft part 400, and the pressure head 401 extends horizontally to one side of the rotating shaft part 400, and the crimping surface at the bottom of the pressure head 401 is a plane, and the crimping surface of the pressure head 401 is parallel to the surface of the circuit board; the rotating shaft part 400 is sequentially penetrated by the workbench 2 and the base 1 from top to bottom, and is rotatably connected to the two. The pressure head 401 rotates with the rotating shaft part 400 into the placement area to press the circuit board in the placement area. It is not difficult to understand that the height between the crimping surface at the bottom of the pressure head 401 and the placement area is equal to or slightly greater than the thickness of the circuit board.

[0033] In this embodiment, the driving assembly 3 is respectively connected to the rotating shaft portion 400 of each clamping assembly 4 for driving the rotating shaft portion 400 of the clamping assembly 4 to rotate. Figure 2 and Figure 3As shown, it includes a driving gear 300 and a transmission gear 301 respectively connected to the rotating shaft portion 400. The driving gear 300 is rotatably connected to the base 1 and / or the workbench 2, and the driving gear 300 is respectively engaged with each transmission gear 301. The rotation of the driving gear 300 can drive the transmission gears 301 to rotate synchronously, so that the rotating shaft portion 400 of the clamping assembly 4 rotates to press or loosen the circuit board in the placement area. Specifically in this embodiment, the rotating shaft of the driving gear 300 is vertically arranged, and the two ends of the rotating shaft of the driving gear 300 are rotatably connected to the base 1 and the workbench 2 respectively.

[0034] For example, the rotating shafts 400 of the three clamping assemblies 4 are coaxially connected with transmission gears 301, and the three transmission gears 301 are distributed along the circumference of the driving gear 300 and are all meshed with the driving gear 300. The rotation of the driving gear 300 can simultaneously drive the three transmission gears 301 to rotate in the same rotation direction, such as rotating counterclockwise or clockwise at the same time.

[0035] In other embodiments, multiple gears may be provided between the driving gear 300 and each transmission gear 301 for transmission. Alternatively, the driving gear 300 may be a driving wheel, and the transmission gear 301 may be a transmission wheel, and the driving wheel and each transmission wheel may be connected by a belt, a chain or the like.

[0036] It is not difficult to understand that in the embodiment of the present application, the rotation angle and rotation speed of the rotating shaft portion 400 of the clamping assembly 4 are affected by the transmission ratio between the driving gear 300 and the transmission gear 301. Therefore, the user or technician can set the transmission ratio between the driving gear 300 and the transmission gear 301 according to the rotation stroke or rotation angle of the pressing head 401 between pressing the circuit board and releasing the circuit board. In other words, the user or technician can design the transmission ratio between the driving gear 300 and the transmission gear 301 to achieve the operation of pressing the circuit board by the pressing head 401 at any rotation angle, making it more versatile.

[0037] In order to facilitate the user or technician to press the circuit board when disassembling the circuit board, in the embodiment of the present application, Figure 1As shown, the driving gear 300 is connected with a handle 302 extending radially outward; the base 1 is connected with a support block 100, and the support block 100 is provided with a guide groove 101 extending in the horizontal direction, and the free end of the handle 302 extends out of the guide groove 101 from the inside to the outside; when the handle 302 moves to one end of the guide groove 101, the pressure head 401 on the shaft part 400 is in a position to release the circuit board, and when the handle 302 moves to the other end of the guide groove 101, the pressure head 401 on the shaft part 400 is in a position to press the circuit board. Therefore, the circuit board pressing operation can be completed by simply moving the handle 302 from one end of the guide groove 101 to the other end of the guide groove 101, which is simple, convenient and fast to operate.

[0038] In some embodiments, Figure 1 or Figure 3 As shown, the working plane 200 is partially recessed downward to form a receiving groove 201 for receiving the circuit board, and the bottom center of the receiving groove 201 forms a placement area. Multiple clamping components 4 are arranged in the receiving groove 201, and the top of the pressure head 401 of the clamping component 4 does not extend out of the working plane 200. In the embodiment of the present application, the shape of the receiving groove 201 is set to match the shape of the circuit board, so that the circuit board is not easy to move in the placement area, so that the pressing of the pressure head 401 is more stable and firm.

[0039] In the embodiment of the present application, a plurality of support columns 102 are connected between the workbench 2 and the base 1, and the drive assembly 3 is connected in the space between the workbench 2 and the base 1. The circuit board disassembly tool has a compact structure, a small overall volume and does not occupy space on the operating table.

[0040] For example, four support columns 102 are provided and distributed at the four corners of the workbench 2 , and the upper and lower ends of the support columns 102 are fixedly connected to the workbench 2 and the base 1 respectively.

[0041] In other embodiments, the circuit board disassembly tool can also be configured as an intelligent or automated disassembly tool, which is more convenient for users or technicians to use; specifically, the drive assembly 3 also includes a drive motor, which is connected to the drive gear 300 in a transmission manner, and the workbench 2 is connected with a detection module for detecting whether there is a circuit board in the placement area, and the detection module is connected to the control circuit of the drive motor. When the circuit board is detected in the placement area, the control circuit controls the drive motor to rotate so that the clamping assembly 4 presses the circuit board. Among them, the detection module can be an infrared sensor, a camera, etc. When the detection module detects that there is a circuit board in the placement area, the control circuit controls the drive motor to rotate to drive the rotating shaft 400 and the pressure head 401 of the clamping assembly 4 to rotate to press the circuit board. After the circuit board is disassembled, the button of the drive motor is pressed again to make the pressure head 401 rotate in the opposite direction to loosen the circuit board.

This is only for the convenience of description, and does not indicate or imply that the device or component must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it cannot be understood as a limitation on the present application.
