A movable floating sensor welding head device

Abstract

The invention relates to the technical field of sensor spot welding, and discloses a movable floating sensor welding head device, which includes a box body, a support plate is fixedly connected to the inside of the box body, and a positioning block is clamped on the upper part of the support plate. The side of the positioning block away from the support plate is elastically connected with a spring, and the end of the spring away from the positioning block is fixed with a magnetic block through a bracket. The side of the magnetic block away from the support is magnetically attracted by an electromagnet, and the lower part of the support plate is hinged with a connecting rod. mechanism, the lower part of the link mechanism is hinged with a fine-tuning device, and the lower end of the fine-tuning device is fixedly equipped with a welding head. The fine-tuning device includes a fine-tuning rod, one end of the fine-tuning rod is hinged with the Locking rod, the lower part of the locking rod is sleeved with a locking sleeve, the surface of the locking sleeve is provided with a chute, the surface of the chute is slidably connected with a limit rod, and the end of the limit rod away from the chute is movably connected with a fixed block.

Description

technical field [0001] The invention relates to the technical field of sensor spot welding, in particular to a movable floating sensor welding head device. Background technique [0002] Home appliances are commonly used in people's daily life. There are many types of home appliances. In the process of using home appliances, due to improper operation, aging lines and other reasons, home appliances often cannot be used normally, and corresponding parts need to be replaced and repaired. In the process of home appliance repair, there are often many faults on the circuit board in the sensor, so it is necessary to disassemble the circuit board and repair the damaged place.

[0002] Home appliances are commonly used in people's daily life. There are many types of home appliances. In the process of using home appliances, due to improper operation, aging lines and other reasons, home appliances often cannot be used normally, and corresponding parts need to be replaced and repaired. In the process of home appliance repair, there are often many faults on the circuit board in the sensor, so it is necessary to disassemble the circuit board and repair the damaged place. When repairing the circuit board, spot welding is often required. The circuit is connected, and the circuit board needs to be moved continuously during the spot welding process, but the circuit board needs to be fixed during the spot welding operation to avoid affecting the maintenance effect due to the shift of the spot welding position due to movement. Because the circuit board in the sensor is a precision component, a slight movement will cause the entire circuit board to be scrapped. Although the existing spot welding devices have movable welding heads, the movement range is too limited, and some have a large movement range. , but can not be fine-tuned, spot welding is mostly manual operation, a little force will deviate from the spot welding position, so a new type of spot welding device came into being
