Description

Technical Field

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

[0002] Circuit boards are a commonly used electrical component. They are also used in the oven manufacturing process, playing an important role in the mass production of fixed circuits and optimizing the layout of the internal circuits of the oven. During circuit board processing, clamping devices are required to fix the circuit boards in place.

[0003] Currently, there are many types of clamping devices for circuit board processing. For example, a clamping device for circuit board processing with Chinese patent number CN202222397870.X includes a base, on which two fixed plates are symmetrically fixedly connected to the upper surface. A transverse lead screw is rotatably connected between the two fixed plates, and a moving block is threaded onto the surface of the transverse lead screw. An extension plate is fixedly connected to the top of both the left fixed plate and the moving block, and a shaft is rotatably connected to the surface of both extension plates. This clamping device for circuit board processing places the circuit board on the surface of the two fixed clamping plates. By controlling the electric push rod to move the moving clamping plate closer to the fixed clamping plate, the circuit board can be clamped and fixed. By setting a flipping mechanism, during the clamping process, the electric telescopic rod is controlled to drive the rack to extend and retract. By using the rack to mesh with the gear plate, the shaft can be driven to flip, thereby achieving the purpose of flipping the circuit board. This is beneficial for adjusting the processing angle and processing surface of the circuit board, eliminating the need for secondary clamping and improving the efficiency of circuit board processing. However, since this device only has the functions of rotation and gap adjustment, it cannot effectively flip some circuit boards with larger specifications. Utility Model Content

[0021] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-4The circuit board processing clamping device in this embodiment includes a processing table 1 and a lifting frame 2. The upper part of the processing table 1 is fixedly connected to the bottom of the lifting frame 2. The processing table 1 is provided with a height adjustment mechanism 3 extending into the interior of the lifting frame 2. The height adjustment mechanism 3 is provided with two clamping adjustment mechanisms 4.

[0023] The height adjustment mechanism 3 includes a slow-drive motor 301. The slow-drive motor 301 is fixedly installed on the right side wall of the processing table 1. A rectangular gear 302 is provided at the output end of the slow-drive motor 301. First, the slow-drive motor 301 drives the rectangular gear 302 to rotate stably. A set of bearings 303 is fixedly installed inside the processing table 1. A double-acting lead screw 304 extending to the outside of the right side of the processing table 1 is fixedly connected to the inner wall of the bearings 303. The threads on the left and right sides of the double-acting lead screw 304 are symmetrical. A rectangular gear connected to the rectangular gear 302 is provided at one end of the double-acting lead screw 304 extending to the outside of the right side of the processing table 1. In the second type 305, the teeth on rectangular gear 1 302 and rectangular gear 2 305 are matched and meshed. This meshing relationship allows the bidirectional lead screw 304 on bearing 1 303 to rotate stably. Two rectangular gears 306 are located on one side of the bidirectional lead screw 304 inside the machining table 1. A set of bearings 2 307 is fixedly installed in each of the two support walls of the lifting frame 2. Each set contains two bearings 303 and two bearings 307. The inner wall of each set of bearings 2 307 is fixedly connected to an extension extending to the machining table 1. The internal one-way lead screws 308 have symmetrical threads on two of them. Each one-way lead screw 308 has a rectangular gear 309 extending into the machining table 1 at one end. The two rectangular gears 309 are movably connected to two rectangular gears 306, with the teeth of the rectangular gears 306 and 309 meshing together. This meshing relationship between the rectangular gears 306 and 309 allows the one-way lead screws 308 on the two sets of bearings 307 to rotate synchronously and stably. The outer walls of the two one-way lead screws 308... Each of the two movable blocks 310 is threadedly connected to a limit guide plate 311 fixedly installed at one end of each movable block 310. The two support walls of the lifting frame 2 are provided with limit grooves that are adapted to the limit guide plate 311. The inner wall of the limit groove is connected to the outer wall of the limit guide plate 311, and the connection between the two is a sliding connection. Finally, by setting the movable block 310 and the guide limit plate 311 on each one-way screw 308, the two movable blocks 310 can generate stable up and down displacement according to the rotation direction of their respective one-way screw 308, thereby completing the height adjustment work and effectively improving the practicality of the clamping device.

[0024] In the implementation of the case, each clamping adjustment mechanism 4 includes an electrically controlled telescopic rod 401. The electrically controlled telescopic rod 401 is fixedly installed on the adjacent surfaces of the two movable blocks. Firstly, the electrically controlled telescopic rod 401 can freely adjust the distance between the two clamping adjustment mechanisms 4. Each electrically controlled telescopic rod 401 has a damping shaft 402 at its movable end. Then, the damping shaft 402 can give the clamping device the function of left and right rotation. A U-shaped block 403 is fixedly connected to the end of the damping shaft 402 away from the electrically controlled telescopic rod 401. Two return springs 404 are fixedly installed on the U-shaped block 403. The tops of the two return springs 404 are fixedly... A connecting plate 405 is fixedly connected, and a pull ring 406 is fixedly installed on the top of the connecting plate 405. A movable rod 407 that penetrates the upper wall of the U-shaped block 403 is fixedly installed on the bottom of the connecting plate 405. An upper clamping piece 408 is fixedly connected to one end of the movable rod 407 that extends into the interior of the U-shaped block 403. A lower clamping piece 409 that matches the upper clamping piece 408 is fixedly installed inside the U-shaped block 403. Finally, the clamping function can be realized through the linkage between the U-shaped block 403, the return spring 404, the connecting plate 405, the pull ring 406, the movable rod 407, the upper clamping piece 408, and the lower clamping piece. It is highly practical.

[0025] In the case implementation, a set of fixing plates 5 are set on both the left and right sides of the processing table 1. There are two fixing plates 5 in each set, and each fixing plate 5 has holes. This design allows the operator to use bolts or studs to fix the clamping device, so as to avoid shaking during processing and affecting the processing quality.

[0026] In the implementation of the case, a controller 6 is installed on the left side wall of the lifting frame 2. The controller 6 is electrically connected to the electronic components in this patent through wires, which facilitates the operation of the controller 6 to control the operation of the electronic components.

[0027] When implementing this procedure, please follow these steps:

[0028] 1) First, the rectangular gear 302 is driven to rotate stably by the slow-drive motor 301;

[0029] 2) Then, by utilizing the meshing relationship between rectangular gear 302 and rectangular gear 305, the bidirectional lead screw 304 on bearing 303 can also rotate stably.

[0030] 3) Furthermore, the rectangular gear 306 and rectangular gear 4 are also meshed, so that the one-way screws 308 on the two sets of bearings 2 307 can generate stable rotation synchronously.

[0031] 4) Finally, by setting a movable block 310 and a guide limit plate 311 on each one-way screw 308, the two movable blocks 310 can generate stable vertical displacement according to the rotation direction of their respective one-way screws 308, thereby completing the height adjustment work.

[0032] In summary, this circuit board processing clamping device, by setting a height adjustment mechanism 3, firstly drives the rectangular gear 302 to rotate stably via the slow-drive motor 301. Then, utilizing the meshing relationship between the rectangular gear 302 and the second rectangular gear 305, the bidirectional lead screw 304 on the first bearing 303 can also rotate stably. Furthermore, the meshing relationship between the third rectangular gear 306 and the fourth rectangular gear 309 allows the unidirectional lead screws 308 on the two sets of second bearings 307 to rotate synchronously and stably. Finally, by setting a movable block 310 and a guide limit plate 311 on each unidirectional lead screw 308, the two movable blocks 310 can generate stable vertical displacement according to the rotation direction of their respective unidirectional lead screws 308, thus completing the height adjustment work. This effectively improves the practicality of the clamping device and solves the problem that the device only has the functions of rotation and gap adjustment, which makes it impossible to effectively flip some large-sized circuit boards.
