Each host device 111 is known to include The spot welding power supply and the spot welding power regulation structure provide welding current for two parallel electrode welding heads.

The structure of one of the two welding head clamps arranged side by side is further described below in conjunction with accompanying drawing 2. In FIG. Two square sliding shaft connection ports 205,206 are respectively arranged on the rear clamping blocks 203,204 of the head clamp, and can be connected with the sliding shafts of two spot welding machine heads respectively by the sliding shaft connection ports 205,206.

If the welding is good, Through two parallel electrode welding heads, the electronic components and the detection circuit are connected in a loop, and the detection circuit sends out normal display signals, including sound, light, and electrical signal display. If the welding effect is not good, the electronic components and the detection circuit cannot form a circuit.

The cone-shaped cube in the lower half of the horn is called the horn head; the farthest end from which the cone-shaped cube horn extends is called the horn tip.

For ease of description, the present invention uses the prestressed electrode welding head, ohmic contact parallel electrode welding head and The tip-contact parallel electrode welding head is summarized and called welding tip-contact parallel electrode welding head. The tips of two electrodes are neither in contact nor conjoined, but parallel electrode welding heads that are insulated and connected to each other are called welding tip insulated parallel electrode welding heads.

After clarifying the basic structure of the parallel electrode welding head in the prior art, the parallel electrode welding head with a thread cutter in the present invention can be divided into three types: A type, B type, and C type because of the difference in the structure of the welding tip: A type For welding tip one-piece parallel electrode welding head with wire cutter, B type is welding tip contact parallel electrode welding head with wire cutter, C type is welding tip insulated parallel electrode welding head with wire cutter, here you need Illustrate, the electronic component automatic welding production equipment of the present invention can use the parallel electrode welding head of A type and B type band cutting knife, and the parallel electrode welding head of C type band cutting knife is only suitable for welding metal strip, metal wire.

There is a small separation groove 507 between the two tips of 505A.

In Figure 6, the main body of the welding head is 601, and the two electrodes of the main body of the welding head are Intermediate insulating interlayer 602 is arranged, and welding head is 603, and welding portion 604 is arranged on welding head 603, is processed with thread cutter portion 605 on the right facade of welding head 603, and the welding portion 604 and thread cutter portion 605 The base is a conjoined structure of the inherent metal of the welding head 603. The welding part 604 is extended and processed to form a welding tip 604A. The end surface of the welding tip is a planar structure. There is a small separation groove 606 between the two sharp ends of the thread cutter sharp end 605A.
