Description

Technical Field

[0001] The utility model relates to the technical field of circuit board clamping tools, in particular to a batch clamping tool for SMT patch processing. Background Art

[0002] SMT is the abbreviation of Surface Mount Technology, which is the most popular technology and process in the current electronic assembly industry. SMT patching refers to the abbreviation of a series of process flows processed on the basis of a PCB. The PCB is a printed circuit board. Due to the different sizes and shapes of circuit boards, when processing circuit boards at present, it is often necessary to fix them through clamping equipment. When the existing clamping equipment fixes the circuit board, since it needs to be relatively tight during clamping and the clamping force is difficult to control, when fixing the circuit board and clamping the circuit board, the damping effect of the clamping equipment is poor and the protection effect on the circuit board is poor. Publication (Announcement) No.: CN217307996U, a batch clamping tool for SMT patch processing, includes a mounting frame and a plurality of clamping frames arranged on the mounting frame. The inside of the clamping frame is provided with a damping sleeve to perform damping treatment on the straight plate and the clamping assembly. The clamping assembly clamps the circuit board by setting the cooperation of the first plate body and the second plate body. The position between the two straight plates is adjusted by setting the cooperation of the pull rod, the pull ring and the plug rod, etc. The clamping stability and safety are high. The overall tooling structure is simple and the operation is convenient. The clamping effect on the circuit board is good and it has stronger practicability.
