Description

Technical Field

[0001] The utility model relates to the technical field of integrated circuit board assembly, in particular to a safety auxiliary crimping fixture for integrated circuit board assembly. Background Art

[0002] During the assembly process of integrated circuit boards, it is often necessary to fix a small flat nut at a specified position on the integrated circuit board. The assembly of the flat nut on the integrated circuit board can be performed by crimping, placing the flat nut at a specified position on the integrated circuit board and then crimping and fixing it.

[0003] Before the flat nut and the integrated circuit board are crimped and fixed, the fit between the flat nut and the integrated circuit board is not precise and stable. If the flat nut is tilted before crimping, the flat nut and the circuit board cannot be guaranteed to be perpendicular after the crimping machine presses down. Therefore, during the crimping process, in order to avoid the tilt of the flat nut, it is necessary to manually hold the flat nut with hands or auxiliary tools to keep the flat nut level and not tilt.

[0004] No matter you hold the flat nut with your hands or with an auxiliary tool, the hand or the auxiliary tool is still under the crimping machine when the crimping machine is pressed down, which is very dangerous and unsafe. You have to be very careful every time you crimp, slow down the operation steps, and the production efficiency is low. In addition, the flat nut and the circuit board cannot be completely vertical by hand or simple auxiliary tools, the qualified rate is low, and it cannot meet the use requirements, so it needs to be improved.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0018] See also Figure 1~Figure 2 , the utility model embodiment includes:

[0019] like Figure 1 and Figure 2 The safety auxiliary crimping jig for integrated circuit board assembly shown is used to assist in crimping flat head nuts on integrated circuit boards, and includes: a crimping base plate 1, a guide block 7, an elastic support body 8 and a pressing head 3. The top surface of the crimping base plate 1 is concavely provided with a positioning groove 2 corresponding to the integrated circuit board, which can be used to position the integrated circuit board on the crimping base plate 1.

[0020] A pad 4 is provided in the positioning groove 2, and the pad 4 is used to partially lift the bottom surface of the integrated circuit board to ensure the gap between the bottom surface of the integrated circuit board and other areas of the bottom surface of the positioning groove 2, to avoid the components on the integrated circuit board, to prevent the components from contacting the bottom surface of the positioning groove 2, and to ensure that the integrated circuit board is level in the crimping bottom plate 1. The pad 4 and the crimping bottom plate 1 can adopt an integrated structure, and can be processed with a steel plate or an aluminum alloy plate, which has high strength.

[0021] Several mounting holes corresponding to the flat head nuts are provided on the integrated circuit board 1 to facilitate the crimping of the flat head nuts. Pin holes 6 corresponding to the mounting holes are provided on the positioning groove 2 or the pad 4. Figure 2 As shown, the pressure head 3 is arranged above the pin hole 6, and a positioning pin 5 extending downward into the pin hole 6 is arranged at the bottom of the pressure head 3. The positioning pin 5 is inserted and guided through the pin hole 6 to ensure the verticality of the positioning pin 5 and the crimping bottom plate 1. In this embodiment, the pressure head 3 and the positioning pin 5 adopt an integrated concentric structure, thereby ensuring the verticality of the pressure head 3 and the crimping bottom plate 1 and avoiding the problem of force deflection of the pressure head 3 during crimping. The pressure head 3 and the positioning pin 5 can be integrated with steel bars for high strength.

[0022] A guide hole 9 corresponding to and connected to the pin hole 6 is concavely arranged on the bottom surface of the crimping base plate 1, and the guide block 7 and the elastic support body 8 are arranged in the guide hole 9, and the elastic support body 8 is located below the guide block 7. In this embodiment, the elastic support body 8 adopts a spring or an elastic rubber block, and the guide block 7 and the positioning pin 5 are elastically supported by the elastic support body 8. The diameter of the guide hole 9 is larger than the diameter of the positioning pin 5, forming a stepped hole, and the guide block 7 is guided to be raised and lowered through the guide hole 9.

[0023] like Figure 2 As shown, a cover plate 10 covering the guide hole 9 or a screw blocking the guide hole 9 is provided at the bottom of the crimping bottom plate 1 to limit the bottom position of the elastic support body 8 to prevent it from flying off. The cover plate 10 can be fixed to the bottom of the crimping bottom plate 1 with bolts, which is convenient for disassembly and assembly.

[0024] In this embodiment, the diameter of the positioning pin 5 corresponds to the inner diameter of the flat head nut. The positioning pin 5 is used to position the flat head nut on the integrated circuit board 1 to avoid the flat head nut from being skewed during the placement process, thereby ensuring the verticality of the flat head nut and the integrated circuit board on the crimping base plate 1 and avoiding deflection during the crimping process, thereby improving the qualified rate of products after crimping.

[0025] In this embodiment, the diameter of the positioning pin 5 is smaller than the diameter of the pressure head 3, forming a stepped shaft structure. The diameter of the pressure head 3 is large, and can cover the top surface of the flat head nut to perform crimping of the flat head nut. The length of the positioning pin 5 is greater than the length of the inner hole of the flat head nut, ensuring that the positioning pin 5 can pass through the inner hole of the flat head nut and then be inserted into the pin hole 6, and retaining the gap between the pressure head 3 and the top of the pin hole 6, ensuring the downward movement of the pressure head 3 during crimping.

[0026] The crimping method includes the following steps:

[0027] A. Place the crimping base plate 1 on the platform, place the integrated circuit board in the positioning groove 2 of the crimping base plate 1, accurately position it, and use the pad 4 to partially lift the bottom surface of the integrated circuit board to ensure the gap between the bottom surface of the integrated circuit board and other areas of the bottom surface of the positioning groove 2, and ensure that the integrated circuit board is level in the crimping base plate 1;

[0028] B. Put the flat nut into the corresponding mounting hole on the integrated circuit board to perform preliminary positioning of the flat nut. The operation is simple.

[0029] C. Place the pressure head 3 above the flat head nut, and insert the positioning pin 5 downward into the pin hole 6 through the inner hole of the nut. Position the flat head nut through the positioning pin 5 to ensure the verticality of the flat head nut and the integrated circuit board, avoid deflection during the crimping process, and improve the qualified rate;

[0030] D. Send the entire crimping base plate 1 to the corresponding position in the crimping machine, start the crimping machine, press the pressure head 3 downward, and complete the crimping of the flat head nut on the integrated circuit board. There is no need to worry about safety issues and the operation speed can be accelerated.

[0031] F. Remove the crimping base plate from the crimping machine, take out the integrated circuit board that has been crimped, and place a new integrated circuit board that has not been crimped with a flat head nut. Repeat this cycle to improve production efficiency.

[0032] In summary, the utility model discloses a safety-assisted crimping jig for assembling an integrated circuit board, which realizes the positioning and crimping assistance of the flat head nut on the integrated circuit board, ensures the verticality of the flat head nut and the integrated circuit board and the operational safety, and is conducive to improving the crimping speed and efficiency.
