Description

Technical Field

[0001] The utility model relates to the technical field of auxiliary equipment for circuit board production, in particular to a clamping tool used for fixing circuit board production. Background Art

[0002] Circuit boards can be divided into ceramic circuit boards, alumina ceramic circuit boards and aluminum nitride ceramic circuit boards according to the materials they are made of. Circuit boards make circuits miniaturized and intuitive, and play an important role in the mass production of fixed circuits and the optimization of electrical appliance layouts. They can be divided into single-sided boards, double-sided boards and multi-layer circuit boards according to the number of layers. During the production and processing of circuit boards, when electrical components need to be welded to the circuit boards, in order to ensure welding accuracy and improve the production and processing efficiency of the circuit boards, it is often necessary to use circuit board clamping devices used in circuit board production to assist in fixing them.

[0003] The existing clamping tools for fixing circuit boards during production are not easy to clamp and position circuit boards of different thicknesses and widths, and threads are usually used for clamping and fixing during clamping and positioning, which is cumbersome to operate and affects work efficiency. In addition, when processing the circuit board, only one side can be processed. When processing the other side, the electrode plate needs to be removed, turned over and reinstalled, which is inconvenient for the staff to operate. Therefore, a clamping tool for fixing circuit boards during production is proposed.

[0004] A circuit board clamping device for circuit board production disclosed in the announcement number CN219876316U, although, the circuit board clamping device for circuit board production includes: a main unit, which includes a base and a circuit board located directly above the base; a clamping unit, which includes fixed ears fixedly connected to both ends of the upper side wall of the base and a driving motor fixedly installed on one of the fixed ears, the output shaft of the driving motor passes through the fixed ear and is fixedly connected with a bidirectional screw, and the end of the bidirectional screw away from the output shaft of the driving motor is rotatably connected to the other fixed ear, the bidirectional screw is threadedly connected with a symmetrical moving block, and the moving block is rollingly connected to the base, the upper side wall of the moving block is fixedly connected with a corresponding moving seat, and a corresponding clamping cover is installed in the moving seat, and the transverse cross section of the clamping cover is set to an isosceles trapezoid. The utility model does not need to repeatedly screw multiple sets of screws and tightening heads, which greatly improves the efficiency of disassembly and assembly of circuit boards, thereby improving the production and processing efficiency of circuit boards.

[0005] Although the above patent eliminates the need to repeatedly tighten multiple sets of screws and tightening heads, greatly improving the efficiency of disassembly and assembly of circuit boards, thereby improving the production and processing efficiency of circuit boards; however, the device lacks the function of turning over the circuit board. Both sides of the circuit board can be processed without disassembling the circuit board, thereby improving work efficiency.

[0006] Therefore, it is necessary to invent a clamping tool for fixing circuit board production to solve the above problems. Utility Model Content
