Problems solved by technology
Due to the small size of the relay product, the contact spring system is one of the key components. The structure is complex, and the parts are many and smaller (less than 1mm). The contact spring system has 4 pairs of static contact springs, and the height and angle of the solder joints are different. , and there are 2 moving contact springs. At present, the spot welding assembly of the contact spring system can only be completed by manual operation.
To ensure the different angles and heights of each solder joint, it is extremely difficult to clamp and position, the operation is difficult, and the efficiency of spot welding is very low. It takes about 10 minutes for a skilled worker to complete the spot welding of a relay contact spring system, which cannot meet the requirements of mass production. need
Especially because of manual positioning and clamping, it is difficult to guarantee the consistency of spot welding, which cannot meet the quality requirements of relays

The invention relates to spot welding equipment for a contact spring system of a micro-relay, which comprises a positioning platform, a lifting mechanism, an angle positioning clamp and a spot welding clamp. The lifting mechanism fixed on the positioning platform is provided with a liftable working platform. A rectangular positioning block of the angle positioning clamp is positioned on the working platform. The spot welding clamp is clamped in a positioning groove on the top surface of a rotatable disc positioning block of the rectangular positioning block. The spot welding clamp comprises a clamping base and a contact spring clamp. A weldment is placed on a positioning hole of the clamping base, a pin is inserted into the hole and a substrate covers the hole. A clamping groove at the front end of the contact spring clamp is located above the positioning hole. The clamping groove of the equipment clamps a contact spring to be welded, the positioning hole fixes the weldment, the circular positioning block rotatably adjusts the angle of the weldment and the lifting mechanism adjusts the height of the weldment finely so as to position the micro-weldment and the clamp precisely, simplify the operation, guarantee the spot welding quality and improve the efficiency. The working platform drives the spot welding clamp to lift so as to clamp the weldment conveniently.
Description
(1) Technical field [0001] The invention relates to a welding auxiliary technology, in particular to a spot welding equipment of a miniature relay contact spring system. (2) Background technology [0002] Spot welding of the contact spring system is a major challenge during the assembly of miniature relays. Due to the small size of the relay product, the contact spring system is one of the key components. The structure is complex, and the parts are many and smaller (less than 1mm). The contact spring system has 4 pairs of static contact springs, and the height and angle of the solder joints are different. , There are also 2 moving contact springs. At present, the spot welding assembly of the contact spring system can only be completed by manual operation. To ensure the different angles and heights of each solder joint, it is extremely difficult to clamp and position, the operation is difficult, and the efficiency of spot welding is very low. It takes about 10 minutes for a ...
