Semi-automatic point welding machine

Abstract

The invention discloses a semi-automatic point welding machine. The semi-automatic point welding machine comprises a cabinet body (1), a support (2) installed on the upper surface of the cabinet body (1), a point welding mechanism (3) located on the support (2), a vacuum plate (4) located below the point welding mechanism (3) and a first guide rail (5), wherein the first guide rail (5) is used for making the vacuum plate (4) longitudinally slide on the first guide rail and fixed to the upper surface of the cabinet body (1). The semi-automatic point welding machine is characterized in that the point welding mechanism (3) comprises a heat dissipation device (31) and a pressure sensor (32), and the pressure sensor (32) is used for positioning welding points and located in the back of the heat dissipation device (31). The semi-automatic point welding machine is reasonable in design, good in heat dissipation effect and suitable for welding complex pieces, with various different-position welding points, to be welded, and point welding positioning is fast and accurate.

Description

technical field [0001] The invention relates to a semi-automatic spot welding machine, in particular to a semi-automatic spot welding machine used for spot welding between metal components in electronic products. Background technique [0002] Spot welding technology has been widely used at present. Many weldments usually have multiple welding spots. Usually, when welding, the object to be welded is usually fixed on the weldment fixing seat first, and the height and height of the welding head are adjusted. Angle, move the fixed seat by hand, and weld all the spots to be welded one by one. This method is not only inefficient and labor-intensive, but also affects the operator's proficiency, manual displacement during spot welding, and operational fatigue. Cause spot welding defects, resulting in unstable welding quality, high production costs; also appeared in the prior art can be in the vertical direction to achieve up and down reciprocating welding head, the use of this weldi...

[0002] Spot welding technology has been widely used at present. Many weldments usually have multiple welding spots. Usually, when welding, the object to be welded is usually fixed on the weldment fixing seat first, and the height and height of the welding head are adjusted. Angle, move the fixed seat by hand, and weld all the spots to be welded one by one. This method is not only inefficient and labor-intensive, but also affects the operator's proficiency, manual displacement during spot welding, and operational fatigue. Cause spot welding defects, resulting in unstable welding quality, high production costs; also appeared in the prior art can be in the vertical direction to achieve up and down reciprocating welding head, the use of this welding head can be improved to a certain extent for only The welding efficiency of the weldment of one solder spot, but because the position of the welding head on the horizontal plane cannot be adjusted, it is still not suitable for components with multiple solder joints; in addition, the current spot welding head generally has no heat dissipation device, and the spot welding head will During the operation, there will be misoperation or damage to the spot welding head due to excessive temperature; in addition, the current spot welding device generally cannot quickly and accurately locate the spot to be welded, resulting in long spot welding time and deviation of the spot welding position.
