Description

Technical Field

[0001] This utility model relates to the field of PCB board processing, and in particular to a terminal clamping and releasing mechanism. Background Technology

[0002] In the PCB assembly process of products such as communication equipment, automotive electronics, and industrial control modules, terminals are the core components for circuit interconnection. The reliability of their clamping and release directly determines the terminal insertion accuracy, pin integrity, and subsequent circuit conduction performance. The process of inserting terminals into PCB boards mainly relies on two methods: manual assembly or automated gripper assembly. However, there are still key technical defects in the actual application of automated gripper assembly.

[0003] Based on existing technology, the inventors, in conjunction with relevant technologies, discovered in practical applications that existing technologies can only clamp the terminals and cannot actively release them. This would cause the terminals to be pulled out of the newly inserted PCB board, resulting in poor insertion and reduced work efficiency. Utility Model Content

[0004] To address the problem that existing technologies can only clamp terminals but cannot actively release them, this utility model provides a terminal clamping and releasing mechanism.

[0005] The terminal clamping and releasing mechanism provided by this utility model adopts the following technical solution:

[0006] A terminal clamping and releasing mechanism includes a base, a guide rail mounting seat bolted to the outer wall of the base, a z-axis guide rail bolted to the guide rail mounting seat, a slider slidably connected to the z-axis guide rail, an x-axis guide rail bolted to the outer wall of the slider, a finger mounting seat bolted to the x-axis guide rail, a clamping mechanism bolted to the bottom end of the finger mounting seat, and a finger guide block bolted to the bottom end of the outer wall of the base. A guide hole is formed on the surface of the finger guide block, through which the clamping mechanism passes. The clamping mechanism is driven by the finger guide block to clamp and release the terminal.

[0007] Furthermore, the clamping mechanism includes a finger, a spring gripper, and a gripper mounting block. The bottom of the finger mounting base is connected to the finger by bolts. A groove is provided inside the finger, and a spring gripper is provided inside the groove. Two spring grippers are symmetrically arranged. The rear wall of the finger is connected to the gripper mounting block by bolts for fixing the spring gripper inside the finger. The spring gripper cooperates with the guide hole.

[0008] Furthermore, a limit block is bolted to the top of the z-axis guide rail, and the limit block is used to prevent the slider from sliding beyond the limit.

[0009] Furthermore, the spring gripper includes a spring and a gripper. The gripper includes a driving part, a clamping part, and a protrusion. A rotating shaft is provided between the driving part and the clamping part. The gripper is rotatably connected to a groove inside the finger via the rotating shaft. The protrusion is located on the outside of the finger. A second spring groove is provided at the top of the protrusion. A first spring groove corresponding to the second spring groove is provided at the bottom of the finger. A spring is provided between the first spring groove and the second spring groove.

[0010] Furthermore, a mating hole is provided on the outer wall of the finger, and one side of the driving part is set as an inclined surface. The inclined surface extends through the mating hole to the outer side of the finger. When the finger moves downward, the driving part contacts the edge of the guide hole, causing the two driving parts to retract inward and compress the spring. The two clamping parts open relative to each other under the action of the rotating shaft, thereby releasing the terminal.

[0011] Furthermore, the edges of the guide hole are rounded.

[0012] Furthermore, the grippers are made of nylon material;

[0013] Furthermore, the finger guide block is made of alloy steel.

[0014] Furthermore, the spring is a stainless steel spring.

[0015] In summary, the beneficial effects of this utility model are as follows:

[0016] This invention features a clamping mechanism that makes terminal clamping more stable and efficient, releasing the terminal at a predetermined position. This mechanism is highly versatile, stable, and flexible, solving the problem of limited gripping functionality in existing clamping mechanisms. During gripping, the mechanism maintains effective contact with the object surface at all times, improving gripping efficiency while simultaneously enhancing reliability and stability. This clamping mechanism eliminates the need for additional components such as cylinders to drive the grippers, significantly reducing the number of parts in the insertion mechanism, simplifying the control system, reducing installation space, saving costs, lowering maintenance and upkeep difficulties, and significantly improving operational safety.

Detailed Implementation

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 The present invention will be further described in detail below:

[0024] This utility model discloses a terminal clamping and releasing mechanism, such as... Figure 1 , Figure 2As shown, this utility model discloses a terminal clamping and releasing mechanism, including a base 1. A guide rail mounting seat 2 is bolted to the outer wall of the base 1. A z-axis guide rail 4 is bolted to the guide rail mounting seat 2. A slider 5 is slidably connected to the z-axis guide rail 4. An x-axis guide rail 7 is bolted to the outer wall of the slider 5. A finger mounting seat 6 is slidably connected to the x-axis guide rail 7. A clamping mechanism is bolted to the bottom end of the finger mounting seat 6. A finger guide block 9 is bolted to the bottom end of the outer wall of the base 1. A guide hole 91 is formed on the surface of the finger guide block 9, through which the clamping mechanism passes. The clamping mechanism is driven by the finger guide block 9 to clamp and release the terminal 13. In this embodiment, the guide rail mounting seat 2 is bolted to the outer wall of the base 1, and the z-axis guide rail 4 is bolted to the guide rail mounting seat 2. On the mounting base 2, the stability of the z-axis guide rail 4 is better ensured. The slider 5 slides on the z-axis guide rail 4, allowing the slider 5 to move up and down. The x-axis guide rail 7 is bolted to the outer wall of the slider 5. The finger mounting base 6 slides on the x-axis guide rail. Through the x-axis guide rail 7, the finger mounting base 6 slides left and right. The finger guide block 9 is bolted to the outer wall of the base 1. The guide hole 91 is opened on the surface of the finger guide block 9. The clamping mechanism and the finger guide block 9 drive the clamping and releasing of the terminal 13. By setting the clamping mechanism, the mechanism can clamp the terminal 13 and release the terminal 13 at the set position, so that the terminal 13 can be inserted into the PCB board without pulling the terminal 13 out of the PCB board. The clamping of the terminal 13 is more stable and efficient, greatly improving the work efficiency. Preferably, the top of the Z-axis guide rail 4 is connected to a limit block 3 by bolts. The limit block 3 is used to prevent the slider 5 from sliding beyond the limit, so as to prevent the slider 5 from sliding out of the Z-axis guide rail 4 and reducing work efficiency. Preferably, the finger guide block 9 is made of alloy steel. Alloy steel is wear-resistant, has high strength, and can withstand greater extrusion force, which extends the life of the finger guide 9 and improves work efficiency. Preferably, the edge of the guide hole 91 is rounded. Making it rounded makes the clamping mechanism easier to insert and more accurately aligned, while avoiding rigid friction or collision damage between the clamping mechanism and the edge of the hole.

[0025] like Figure 1 , Figure 2 , Figure 4As shown, the clamping mechanism includes a finger 8, a spring gripper 12, and a gripper mounting block 15. The bottom of the finger mounting base 6 is bolted to the finger 8. A groove is formed inside the finger 8, and a spring gripper 12 is disposed inside the groove. Two spring grippers 12 are symmetrically arranged. The rear wall of the finger 8 is bolted to the gripper mounting block 15 for fixing the spring gripper 12 inside the finger 8. The spring gripper 12 cooperates with the guide hole 91. In the embodiment, the finger 8 is bolted to the bottom of the finger mounting base 6. The groove inside the finger 8 is used to place the spring gripper 12. There are two symmetrical spring grippers 12, thereby realizing the clamping terminal 13 and the releasing terminal 13. The gripper mounting block 15 is bolted to the rear wall of the finger 8 to better fix the spring gripper 12 inside the finger 8. The spring gripper 12 cooperates with the guide hole 91 to realize the clamping terminal 13 and the releasing terminal 13.

[0026] like Figure 5 As shown, the spring gripper 12 includes a spring 11 and a gripper 14. The gripper 14 includes a driving part 1401, a clamping part 1402, and a protrusion 1403. A rotating shaft 16 is provided between the driving part 1401 and the clamping part 1402, allowing the gripper 14 to be rotatably connected to a groove inside the finger 8 via the rotating shaft 16. The protrusion 1403 is located on the outer side of the finger 8. A second spring groove 1102 is formed at the top of the protrusion 1403, and a first spring groove 1101 corresponding to the second spring groove 1102 is formed at the bottom of the finger 8. A spring 11 is provided between the first spring groove 1101 and the second spring groove 1102. In this embodiment, the gripper 14 includes a driving part 1401, a clamping part 1402, and a protrusion 1403. The rotating shaft 16 is located between the driving part 1401 and the clamping part 1402, allowing the gripper 14 to be rotatably connected to a groove inside the finger 8 via the rotating shaft 16. The gripper 14 in the groove inside the finger 8 rotates to clamp the terminal 13 and release the terminal 13. The outer side of the finger 8 is provided with a protrusion 1403. The second spring groove 1102 is provided on the top of the protrusion 1403, and the first spring groove 1101 is provided on the bottom of the finger 8, corresponding to the second spring groove 1102. The spring 11 is provided between the first spring groove 1101 and the second spring groove 1102. Preferably, the gripper 14 is made of nylon material. Nylon material is lightweight and low cost. It can protect the surface of the object being gripped from scratches. It has its own elasticity and can cushion the impact, avoiding damage to the PCB board pads. Preferably, the spring 11 is a stainless steel spring. It is not easy to rust in humid environments, is corrosion resistant, has stable elasticity, is low cost, and is easy to purchase. The length and wire diameter can be customized directly according to the space provided by the first spring groove 1101 and the second spring groove 1102.

[0027] like Figure 5As shown, a mating hole 10 is provided on the outer wall of the finger 8. One side of the driving part 1401 is set as an inclined surface, which extends through the mating hole 10 to the outer side of the finger 8. When the finger 8 moves downward, the driving part 1401 contacts the edge of the guide hole 91, causing the two driving parts 1401 to retract inward and compress the spring 11. The two clamping parts 1402 open relative to each other under the action of the rotating shaft 16, thereby releasing the terminal 13. In this embodiment, the mating hole 10 is provided on the outer wall of the finger 8. One side of the driving part 1401 is set as an inclined surface, which extends through the mating hole 10 to the outer side of the finger 8. When the driving part 1401 moves downward, the driving part 1401 contacts the edge of the guide hole 91, causing the two driving parts 1401 to retract inward and compress the spring 11. The two clamping parts 1402 open relative to each other under the action of the rotating shaft 16, thereby releasing the terminal 13 and placing it on the hole in the PCB board.

[0028] The implementation principle of this utility model embodiment is as follows:

[0029] In use, the slider 5 first moves downward via the z-axis guide rail 4. When the slider 5 moves downward, the finger mounting base 2 moves downward as well. When the finger mounting base 2 moves downward, the finger 8 also moves downward. When the finger 8 moves downward to a certain height from the PCB board, the driving part 1401 of the gripper 14 contacts the edge of the guide hole 91, causing the two driving parts 1401 to retract inward and compress the spring 11. The two clamping parts 1402 open relative to each other under the action of the rotating shaft 16, so that the pin of the terminal 13 enters the hole in the PCB board and continues to be inserted downward into the PCB board.

[0030] Finally, when slider 5 moves upward via z-axis guide rail 4, finger mounting base 2 moves upward accordingly. When finger mounting base 2 moves upward, finger 8 also moves upward. When finger 8 moves upward, the gripper will not close instantly. When finger 8 moves upward to a certain height, the drive part 1401 of gripper 14 will not contact the edge of guide hole 91, causing the two drive parts 1401 to extend outward, spring 11 to reset, and the two clamping parts 1402 to clamp relative to each other under the action of rotating shaft 16, thereby performing the next clamping release terminal 13.
