Description

Technical Field

[0001] The present application relates to the field of circuit board processing, and more specifically, to a clamp for circuit board processing. Background Art

[0002] A circuit board is an important component used in electronic devices, usually made of non-conductive materials. There is a thin film on the circuit board with metal lines printed on it, connecting various electronic components, such as resistors, capacitors, integrated circuits, etc. Circuit boards need to be clamped and fixed during manufacturing. The patent document with the prior art publication number CN218487408U provides a clamp for processing circuit boards. The device extracts the limit bolt from the inside of the fixing frame, manually adjusts the rotation of the shaft, and realizes the rotation adjustment of the circuit board with the cooperation of the bearing seat installed between the threaded rod and the limit table. After the rotation adjustment is completed, the limit bolt is inserted into the fixing frame and the limiting hole to limit the position of the shaft inside the fixing frame, thereby increasing the stability of the circuit board during processing.

[0003] With respect to the above-mentioned related technologies, the inventor believes that the device needs to rotate the threaded rod multiple times to adjust the distance between the limit table and the fixed table to clamp the circuit board, which is cumbersome to operate and has low work efficiency. Therefore, we propose a clamp for circuit board processing. Utility Model Content

[0004] In order to improve the problems raised in the above background technology, the present application provides a clamp for processing a circuit board.

[0005] The present application provides a circuit board processing fixture, which adopts the following technical solution:

[0006] A clamp for processing circuit boards comprises a base, to which a placement plate is rotatably connected, one side of the placement plate is slidably connected to two clamping seats, and the other side is elastically connected to a connecting rod, a plurality of racks are fixedly connected to the connecting rod, one side of the rack is meshingly connected to a gear, the gear is rotatably connected to the placement plate, the gear and the clamping seat are connected by two mutually hinged rotating rods, and one end of the connecting rod is rotatably connected to a pull rod.

[0007] By adopting the above technical solution, pulling the pull rod can drive the connecting rod to slide, and the connecting rod drives the rack to translate, so that the rack drives the gear to rotate, and the two rotating rods between the gear and the clamping seat are arranged in a V shape, and the multiple groups of rotating rods are arranged symmetrically. When the gear rotates, it cooperates with the rotating rod to drive the clamping seat to translate, and the two clamping seats slide in opposite directions, thereby quickly adjusting to adapt to the spacing of the circuit board and clamping it.

[0008] Optionally, both ends of the placement plate are fixedly connected with a rotating block, and the rotating block is rotatably connected to a fixed rod fixedly connected to the base.

[0009] By adopting the above technical solution, the rotating block cooperates with the fixing rod to rotate the placement plate, so that the orientation can be adjusted after clamping the circuit board, thereby improving the convenience of operation.

[0010] Optionally, a bolt is threadedly connected to the fixing rod, and one end of the bolt is abutted against the rotating block.

[0011] By adopting the above technical solution, after one end of the bolt is tightly in contact with the rotating block, the rotation of the placement plate can be limited to make it hover stably.

[0012] Optionally, the connecting rod is slidably connected to the placement plate, and a spring is sleeved on the connecting rod, and two ends of the spring are respectively connected to the connecting rod and the placement plate.

[0013] By adopting the above technical solution, when the connecting rod is not subjected to external force, the spring is in a contracted state. At this time, the two clamping seats are closest to each other. When the pull rod is pulled to drive the connecting rod to move, the two clamping seats move away from each other. After the pull rod is released, the spring drives the clamping seat to clamp the circuit board.

[0014] Optionally, a plurality of limit plates are fixedly connected to the pull rod, a U-shaped seat is fixedly connected to the placement plate, a plurality of fixing plates are fixedly connected to the U-shaped seat, and the limit plates are in abutment with the fixing plates.

[0015] By adopting the above technical solution, after the clamping seat clamps the circuit board, the pull rod is rotated to make the limit plate contact with the fixed plate, which can prevent the connecting rod from moving and improve the stability of the clamping seat clamping the circuit board.

[0016] In summary, the present application includes at least one of the following beneficial technical effects:

[0017] 1. When the connecting rod is moved by pulling the pull rod, the rack drives the gear to rotate, and the gear and the rotating rod cooperate to drive the clamping seat to move, so that the two clamping seats can quickly move away from each other and adjust the spacing to suit the circuit board, thereby realizing rapid clamping and cancellation of the circuit board. The operation is simple and convenient to use.

[0018] 2. After the circuit board is clamped by the clamping seat, the pull rod is rotated to make the limit plate abut against the fixed plate, which can limit the sliding of the connecting rod, so that the clamping seat can stably clamp the circuit board and improve stability.
