Fixing device for spot welding of circuit boards of household appliances

Abstract

The invention discloses a spot welding fixing device for a home appliance circuit board, which comprises a base, a column, a beam and a placing table; Straight down the sleeve, the lower end of the sleeve is inserted with a telescopic rod; the sleeve is slidably provided with a slider, a spring is fixedly connected between the slider and the telescopic rod, and a permanent magnet is fixedly installed on the upper side of the slider. An electromagnet is fixedly installed on the top of the corresponding sleeve above the permanent magnet; a rotating shaft is installed at the lower end of the telescopic rod, and the rotating shaft is installed on the pressing plate through a bearing. The present invention can ensure that the circuit rotates in the spot welding process and faces different directions through the provided rotating table and the rotating pressing plate, which not only ensures that the circuit board is not pressed during welding, but also ensures that the circuit board is rotated conveniently, which brings convenience to the operation of the maintenance personnel. Improve maintenance efficiency and avoid inaccurate spot welding positions affecting maintenance results.

Description

technical field [0001] The invention relates to a home appliance maintenance equipment, in particular to a spot welding fixing device for a home appliance circuit board. Background technique [0002] Household appliances are commonly used in people's daily life. There are many kinds of home appliances. During people's daily use, due to improper operation, aging lines and other reasons, the home appliances cannot be used normally, and the corresponding parts need to be replaced and repaired. In the process of repairing home appliances, there are often many faults on the circuit board. The circuit board needs to be disassembled and repaired according to the damaged area. When the circuit board is repaired, the circuit needs to be connected by spot welding. During the spot welding process of the circuit board, it is necessary to The circuit board is constantly moved, but it is necessary to fix the circuit board during spot welding, so as to avoid the deviation of the spot weldi...

[0002] Home appliances are commonly used in people's daily life. There are many kinds of home appliances. During daily use, due to improper operation, aging lines and other reasons, the home appliances cannot be used normally, and the corresponding parts need to be replaced and repaired.

In the process of repairing home appliances, there are often many faults on the circuit board. The circuit board needs to be disassembled and repaired according to the damaged area. When the circuit board is repaired, the circuit needs to be connected by spot welding. During the spot welding process of the circuit board, it is necessary to The circuit board is constantly moved, but it is necessary to fix the circuit board during spot welding, so as to avoid the deviation of the spot welding position caused by its movement and affect the maintenance effect. Therefore, it is necessary to design a fixing device for the spot welding of the circuit board. Ensure accurate spot welding
