Technical field

[0001] The utility model belongs to the technical field of welding slag cleaning, in particular to an automatic welding slag cleaning device. [Background Technology]

[0002] Connector production often involves welding to connect different components. The welding process produces welding fumes and slag that gradually accumulate on the surface of the product, resulting in a poor appearance. Traditionally, brushes are used to clean weld slag, but this method is ineffective and inefficient.

[0003] Patent CN220362108U in the prior art discloses an automatic welding smoke and slag cleaning device and a radium welding processing line. A conveyor line transports products from a welding station for welding operations to a cleaning station. A dry ice nozzle is installed at the cleaning station, and dry ice particles ejected from the dry ice nozzle are used to clean the product surface, effectively removing welding slag and significantly improving the efficiency and effectiveness of welding slag cleaning. However, dry ice purging is not suitable for the entire surface of some fragile products. For example, electrical connectors, whose exposed metal terminals are not suitable for impact purging with cooler dry ice, can easily affect the strength of the metal terminals and shorten their service life. Furthermore, after the welding slag treatment, it is impossible to determine whether the product has been cleaned properly, requiring manual visual inspection, which is inefficient and requires additional personnel and processes.

[0004] Therefore, it is necessary to provide a new welding slag automatic cleaning device to solve the above technical problems. [Utility Model Content]

[0025] A first supporting plate 21 is provided at the movable end of the X-axis transfer mechanism 2 .

[0026] The clamp 1 includes a slider seat 11 fixed on the first support plate 21, a fixed clamping block 12 fixed on the slider seat 11, a movable clamping block 13 slidably arranged on the slider seat 11 and cooperating with the fixed clamping block 12 to form a clamping space, and a driving member that drives the movable clamping block 13 to move closer to or away from the fixed clamping block 12.

[0027] In this embodiment, the driving member is an adjustment locking screw 14. An adjustment seat 15 is fixedly mounted on the slider seat 11. The adjustment seat 15 is provided with a threaded hole (not shown). The adjustment locking screw 14 is screwed into and passed through the threaded hole. One end of the adjustment locking screw 14 is fixedly connected to the movable clamping block 13. A rotating adjustment head 16 is fixedly mounted on the other end of the adjustment locking screw 14. In the initial state, the movable clamping block 13 is spaced apart from the fixed clamping block 12. The product 200 to be cleaned of welding slag is placed in the clamping space. The adjustment locking screw 14 is then rotated to bring the movable clamping block 13 closer to the fixed clamping block 12, thereby clamping the product 200 together with the fixed clamping block 12.

[0028] In other embodiments, the driving member may also be a mechanical toggle clamp, a cylinder, an elastic clamp block, etc.

[0029] The protective cover 7 is located on the first support plate 21 and encloses the fixture 1 to form a clean space. An opening 71 is provided above the dust cover 7 so that the dry ice nozzle 4 can extend into the clean space and align with the part of the product 200 to be cleaned.

[0030] To facilitate replacement of the fixture 1 and improve the versatility of the cleaning device, the protective cover 7 includes a first closing panel 72 and a second closing panel 73 that together form a surrounding barrier structure. One side of the first closing panel 72 and the second closing panel 73 are rotatably connected together by a hinge (not shown in the figure) and the other side is locked together by a locking structure 74. Specifically, on the other side, the first closing panel 72 is provided with a locking seat, and the second closing panel 73 is provided with a lock that cooperates with the locking seat. The rear side of the first closing panel 72 is provided with an exhaust port 75 that communicates with the dust collection mechanism 8.

[0031] This embodiment also includes a work platform 9, which is provided with a frame 91. Frame 91 is provided with a controller 92 and a display screen 93 electrically connected to controller 92. Controller 92 is in electrical signal communication with the X-axis transfer mechanism 2, the visual camera 3, the Y-Z-axis transfer mechanism 5, and the dry ice machine 6. Display screen 93 can display images of the product after weld slag removal or other settings, and provides a human-machine interactive interface.

[0032] The working process of an automatic welding slag cleaning device 100 in this embodiment is as follows: an operator or a robot places the product 200 to be processed on the fixture 1 and clamps it at the loading and unloading station; the X-axis transfer mechanism 2 drives the fixture 1 to move the product 200 to the inspection station, and uses the visual camera 3 to identify the welding slag accumulation position on the product; the X-axis transfer mechanism 2 drives the fixture 1 to move the product 200 to the cleaning station, and the YZ-axis transfer mechanism 5 drives the dry ice nozzle 4 to move into place according to the welding slag accumulation position, and extends it into the inside of the protective cover 7, aligning it with the welding slag docking position, and the dry ice machine 6 is started. Under the action of compressed air, dry ice particles with an extremely low temperature of up to -78.5°C are sprayed towards the product 200, which can effectively remove the welding slag on the product 200 and achieve thorough cleaning. At the same time, the dust suction mechanism 8 sucks away the welding slag generated by the blowing, and collects and processes it in a centralized manner; thereafter, the X-axis transfer mechanism 2 drives the fixture 1 to move the product 200 to the inspection station again, and the visual camera 3 performs online inspection on the surface of the product 200 to detect whether the welding slag is thoroughly cleaned. If it is clean, the X-axis transfer mechanism 2 drives the fixture 1 to bring the product 200 back to the loading and unloading station, and the operator or robot takes out the product 200 and puts in the next product 200 to be processed for the next cycle of cleaning operation; if the cleaning is not thorough, the fixture 1 returns to the cleaning station with the product 200 for a second dry ice blowing, and then goes to the inspection station again to verify the cleaning effect. This process will continue until the welding slag is thoroughly cleaned.

[0033] For those skilled in the art, several modifications and improvements can be made without departing from the inventive concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
