Device, method and system for leak-proof welding detection of welded parts

Abstract

The invention relates to a welded part detection device and discloses a welded part solder skip preventing detection device. The detection device comprises a shell, an examination entrance, a PLC, a welded part bracket, a drive device and a sensor. The drive device is arranged in the shell. The examination entrance is formed in the upper surface of the shell. A detection cavity is formed under the examination entrance. The welded part bracket is connected with the drive device. The drive device drives the welded part bracket to be moved in or out of the detection cavity. When the welded part bracket is moved into the detection cavity, the welded part bracket carries a welded part, when the welded part bracket is moved out of the detection cavity, the welded part falls out of the detection device, and the sensor is arranged in the shell and is close to the welded part carried on the welded part bracket and needing to be welded. The invention further discloses a welded part solder skip preventing detection method and system. The welded part solder skip preventing detection device is simple in structure, and is used in cooperation with a point welding machine for eradicating solder skips and missing detection; the flexibility is high, the structure of the welded part bracket and the position of the sensor are changed according to the specific welded part, and the detection device can be used for detecting different welded part products.

Description

technical field [0001] The invention relates to the field of weldment detection, in particular to a leak-proof welding detection device, method and system for welded parts. Background technique [0002] Spot welding machine is a commonly used welding equipment in the machinery manufacturing industry. During operation, the operator only needs to place the weldment in an appropriate position, and the welding head can complete the welding work of multiple welding spots in sequence under the instructions of the control system, greatly Increased production efficiency. However, due to manual operation problems, sudden machine failure problems of spot welding machines or other reasons, missing welding and virtual welding occur from time to time. Once the missing or false welds are processed to the product, the quality of the product will be greatly reduced and may even require subsequent rework. The more serious situation is that once such products enter the market for consumers ...

Problems solved by technology

The more serious situation is that once such products enter the market for consumers to purchase, when quality problems occur, the impact will damage the reputation of the company if the impact is small, and the personal safety of consumers will be endangered if the impact is large.

[0003] In order to prevent the welding parts from missing welding, at most a spot welding machine is added to the spot welding machine used at present. However, welding points and welding parts are not the same concept, and each welding part on some welding parts requires Weld multiple solder joints, and the counter on the spot welding machine can only count the number of solder joints. It may appear that there are more solder joints on other welding parts, resulting in the number of final solder joints meeting the requirements but missing parts. However, the situation of missing welding of weldments and welding parts still cannot be detected; if the situation of missing welding is checked manually, it is not only labor-intensive and time-consuming, but also the situation of missing inspection cannot be ruled out.
