Description

Technical Field

[0001] This utility model relates to the field of spot welding technology, and in particular to a spot welding device for industrial robot production. Background Technology

[0002] Industrial robots are multifunctional automated mechanical devices used to perform various tasks in industrial environments, such as handling, assembly, and inspection. They typically consist of a robotic arm, controller, teach pendant, and end effector, and can replace or assist humans in completing tasks. Spot welding, when used in the production and processing of industrial robots, utilizes the resistance heat generated by current passing through metal contact points, and under pressure, rapidly melts and fixes multiple layers of metal sheets together.

[0003] A search revealed Chinese patent publication number CN222448676U, which discloses an environmentally friendly spot welding device for industrial robot production. This patent connects one end of an air intake pipe to the front of the housing, and the collection hopper is connected to the other end of the air intake pipe. It can filter some of the harmful substances in the exhaust gas through a filter element, and then discharge the filtered exhaust gas through a suction fan. However, this device has a certain problem: the air inside the housing flows from bottom to top. When the stepper motor drives the cleaning rod to scrape the first filter element, the upward airflow inside the housing causes dust to continue to remain on the first filter element, making it impossible to clean the first filter element effectively.

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] The present invention will be further described below with reference to the accompanying drawings:

[0025] like Figures 1-4 As shown, a spot welding device for industrial robot production includes a workbench 101, a work box 102 fixedly connected to the upper end of one side of the workbench 101, a filter box 103 provided on the other side of the workbench 101, a connecting mechanism provided on the side of the filter box 103 near the work box 102, and a cleaning mechanism provided on the filter box 103.

[0026] The cleaning mechanism includes an exhaust fan 401, which is fixedly installed on the upper part of the filter box 103. A groove 402 is provided at the front end of the filter box 103. A cleaning box 301 is located at the front of the filter box 103, containing a scraping component. Symmetrical limiting plates 405 are fixedly connected to both sides of the cleaning box 301, with gaps at their front ends. A spare filter plate 403 is fixedly installed inside the filter box 103. A main filter plate 404 is slidably connected to the groove 402. A handle is fixed to the front end of the main filter plate 404, which is located below the spare filter plate 403. When in use, the exhaust fan 401 is activated, and the gas generated during welding is drawn into the filter box 103 through the connecting mechanism. Inside 03, after the welding fumes are filtered by the main filter plate 404, the dust and powder carried in them will remain on the main filter plate 404. After long-term use, a large amount of powder will accumulate on the main filter plate 404. The worker pulls the main filter plate 404 to the upper end of the cleaning box 301 by the handle. At this time, the welding fumes are filtered by the spare filter plate 403, so that the handle of the main filter plate 404 is located in the gap of the limiting plate 405. The symmetrical limiting plates 405 limit the main filter plate 404. Then, the main filter plate 404 is cleaned by the scraping component. After cleaning, the main filter plate 404 is pushed into the groove 402 for reset, thereby achieving rapid cleaning of the main filter plate 404 without stopping the machine.

[0027] The scraping assembly includes a cleaning motor 501, which is fixedly installed at the lower end of the workbench 101. The output shaft of the cleaning motor 501 is coaxial with the cleaning box 301. A rotating plate 502 is fixedly connected to the output shaft of the cleaning motor 501. Multiple scrapers 503 are fixed at equal intervals on the upper end of the rotating plate 502. The cleaning motor 501 drives the rotating plate 502 to rotate, so that the rotating plate 502 drives the multiple scrapers 503 to scrape the surface of the main filter plate 404.

[0028] A connecting plate 302 is provided between the cleaning box 301 and the filter box 103. The connecting plate 302 is fixedly connected to the upper end of the cleaning box 301. The main filter plate 404 abuts against the upper end of the connecting plate 302. When the main filter plate 404 is pulled, it slides on the connecting plate 302, thereby ensuring that the main filter plate 404 moves quickly.

[0029] The connecting mechanism includes a connecting pipe 601, which is fixedly connected to the lower end of the filter box 103. A suction bucket 602 is fixedly connected to one end of the connecting pipe 601 near the working box 102. The suction bucket 602 is located at the front end of the working box 102. Welding fumes are drawn into the connecting pipe 601 through the suction bucket 602 and transported to the filter box 103 through the connecting pipe 601.

[0030] A lead screw 201 is rotatably connected to the front end of the work box 102. The lead screw 201 is threadedly connected to the lifting plate 202. A lifting motor 203 is fixed at the upper end of the work box 102. The output shaft of the lifting motor 203 is fixedly connected to the lead screw 201. The lifting motor 203 drives the lead screw 201 to rotate. Through the threaded engagement between the lead screw 201 and the lifting plate 202, the lifting plate 202 is moved downward.

[0031] The upper electrode 701 is fixedly connected to the front end of the lifting plate 202, and the lower electrode 702 is fixedly connected to the upper end of the worktable 101. The upper electrode 701 and the lower electrode 702 are vertically aligned. During spot welding, the upper electrode 701 is driven to descend by the lifting plate 202, which applies pressure to the plate material between the upper electrode 701 and the lower electrode 702 and melts them together.

[0032] The opening of the suction hopper 602 faces the lower electrode 702.

[0033] Working principle: During operation, the lifting motor 203 drives the lead screw 201 to rotate. The lead screw 201 engages with the lifting plate 202 via a threaded connection, causing the lifting plate 202 to move downwards. During spot welding, the lifting plate 202 lowers the upper electrode 701, applying pressure to the plates between the upper and lower electrodes 702 and fusing them together. Welding fumes are generated during the welding process. The exhaust fan 401 is activated, drawing the welding fumes into the connecting pipe 601 through the suction hopper 602. The fumes are then transported to the filter box 103 via the connecting pipe 601. After being filtered by the main filter plate 404, the dust and powder carried by the welding fumes remain on the main filter plate 404. On the 04th, after prolonged use, a large amount of powder accumulates on the main filter plate 404. The worker pulls the main filter plate 404 to the upper end of the cleaning box 301 using the handle. At this time, the welding fumes are filtered through the spare filter plate 403, so that the handle of the main filter plate 404 is located in the gap of the limiting plate 405. The symmetrical limiting plates 405 limit the main filter plate 404. The cleaning motor 501 drives the rotating plate 502 to rotate, so that the rotating plate 502 drives multiple scrapers 503 to scrape the surface of the main filter plate 404. After cleaning, the main filter plate 404 is pushed into the groove 402 for reset, thereby achieving rapid cleaning of the main filter plate 404 without stopping the machine.
