Technical Field

[0001] This disclosure relates to the technical field of automated production, and in particular to a welding needle fixing mechanism and welding equipment. Background Technology

[0002] Currently, with the continuous development of new energy sources, welding pins, as tools for fixing and welding capacitive components, play a role in ensuring welding quality and improving production efficiency in modern electronic manufacturing processes.

[0003] However, in existing welding equipment, when replacing welding needles, the old welding needle needs to be manually removed and a new welding needle needs to be placed in the welding equipment. When replacing the new welding needle, it is often done manually to remove the old welding needle and tighten it on the equipment by turning the equipment. During this turning process, it is easy to cause misalignment and twisting when installing the welding needle. When the new welding needle is misaligned, it will cause the welding needle to be out of position during welding, thus affecting the welding quality. Utility Model Content

The positioning component has a positioning groove, which is used to position the battery during production and the calibration component during debugging. The driving component, the clamping component, and the positioning component are sequentially arranged on the bracket along the welding direction of the welding needle. The calibration component and the positioning component are located at the welding end of the welding needle. The calibration component is disposed in the positioning groove. During debugging, the welding needle passes through the through hole of the clamping component and abuts against the end face of the calibration component.

[0008] In one embodiment, the positioning component further includes a fixing block and a positioning base; the fixing block is connected to the side wall of the bracket, and the bottom of the fixing block abuts against the base; the side wall of the fixing block is provided with a concave surface to form the positioning groove, and the calibration member is in close contact with the concave surface.

[0013] In one of the embodiments, the first clamping part is provided with a fixing hole, and the power shaft of the driving assembly is located in the fixing hole and detachably connected with the first clamping part.

[0014] In one of the embodiments, the first clamping part is provided with a tightening groove in communication with the fixing hole, the clamping assembly further comprises a second threaded stud, the first clamping part is provided with a connecting through hole and a third threaded hole, the connecting through hole and the third threaded hole are in communication with the tightening groove, and the second threaded stud is screwed into the third threaded hole through the connecting through hole to adjust the gap of the tightening groove.

When the welding needle fixing mechanism is in operation, the battery is placed in the positioning groove so that the welding needle can perform welding work within the positioning groove. When the welding needle needs to be replaced, the old welding needle is first removed using the clamping assembly, then the calibration component is placed in the positioning groove, and then the new welding needle is passed through the clamping assembly and simultaneously abuts against the end face of the calibration component. The clamping assembly then clamps and fixes the welding needle in place. By abutting the welding needle against the end face of the calibration component, a fixed point is provided for the welding end of the welding needle. Tightening the welding needle with the clamping assembly avoids the situation where the welding needle position shifts due to the lack of a fixed point during installation, effectively preventing welding defects caused by welding needle position deviation and improving the overall quality and reliability of the product.
