[0013] Compared with the prior art, the present invention provides a photovoltaic inverter housing welding device, which has the following beneficial effects: 1. A photovoltaic inverter housing welding device, when starting to weld the side shell plate and the top cover, start the second motor to rotate the threaded rod, and under the action of the screw principle, the welding gun is prompted to move in the direction of the glass window. During the process, the first slide bar will first slide on the inner side of the slide rail one, so the cleaning brush will first clean the welding surface of the side shell plate and the top cover. When the first slide bar slides into the inner side of the slide rail three through the slide rail two as the welding gun moves, the lever will rotate during the process, causing the cleaning brush to deviate backward and the scraper to deviate forward. Then the second motor starts to output in the reverse direction, so that the connecting block starts to move away from the glass window with the welding gun, and at the same time, the welding gun starts to weld the joint of the side shell plate and the top cover. At this time, the first slide bar slides in the slide rail three, and as the welding gun moves, the scraper will scrape off the welding slag that may exist on the surface of the side shell plate and the top cover, and the scraped welding slag will fall into the connection box. By cleaning in time before and after welding, the overall quality of welding can be effectively guaranteed.

[0014] 2. This photovoltaic inverter housing welding device starts the first cylinder output, and then the side shell plate can be moved backward to the bottom of the first enclosure plate under the drive of the moving plate 1 and the supporting plate. During the process, the second sliding rod slides on the inner side of the connecting groove 4 to enable the lifting plate to move upward. At the same time, when the first tooth plate moves backward with the side shell plate, the gear will prompt the moving plate 3 to push the push plate forward. When the lifting plate moves into the inner side of the first arc plate, the push plate will push the top cover onto the lifting plate, and then the top cover is pushed downward by the output end of the second cylinder, so that the lower end of the top cover contacts the side shell plate, and the lifting plate is completed. The loading work of the side shell plate and the top cover is completed. After the welding is completed, the second cylinder contracts, and the welded side shell plate and the top cover move upward to the first arc plate under the urging of the spring. Finally, by starting the first cylinder to contract, the lifting plate moves forward with the welded side shell plate and the top cover, and the second slide bar passes through the connecting groove four again, so that the lifting plate moves out from under the side shell plate and the top cover, and then the welded side shell plate and the top cover are parked at the upper ends of the two groups of connecting plates two, completing the unloading work after the side shell plate and the top cover are welded. The loading and unloading operation of the device is smooth, making the welding process of the photovoltaic inverter housing more efficient.

[0015] 3. This is a photovoltaic inverter housing welding device. After the side shell plate and the top cover are welded, the second cylinder contracts to make the rotating plate 2 leave the upper end of the top cover, and the lifting plate and the spring lose the pressure. At this time, the spring will bounce up, and push the top cover upward under the support of the lifting plate, and move the side shell plate welded to the top cover out from the inner side of the loading chute. However, in the process of the side shell plate moving upward with the top cover, the gravity of the side shell plate itself can be used to test whether the welding point between the side shell plate and the top cover will break and separate, so as to judge the firmness of the welding and control the factory quality of the housing welding.

[0016] 4. This photovoltaic inverter housing welding device, after the top cover moves to the upper end of the lifting plate, under the push of the output end of the second cylinder, the rotating plate 2 moves downward to push the top cover downward. At the same time, the rotating plate 2 will press on the upper end of the top cover. After the top cover is pushed down to contact the side shell plate, the side shell plate and the top cover are clamped and fixed in cooperation with the support plate. The rotating plate 2 is rotatably connected to the second cylinder, which can not hinder the conversion of the welding surface of the side shell plate and the top cover of the first motor during clamping and fixing, thereby ensuring the stability during welding and avoiding welding deviation.

[0035] When in use, the device is placed on a horizontal ground, and then the side shell plate 2 is placed on the inner side of the loading trough 628, and the top cover 3 that needs to be welded with the side shell plate 2 is placed on the inner side of the storage box 618 in sequence, and the first group of top covers 3 will fall to the inner side of the push plate 617. At this time, the second slide bar 87 is on the inner side of the connecting groove 5 13. When starting to work, the first cylinder 61 is started, and the output end of the first cylinder 61 pushes the moving plate 1 62 to move backward. At the same time, the connecting box 66 and the rotating plate 1 68 are driven to move under the connection of the moving plate 2 65, so that the side shell plate 2 is moved to the bottom of the first enclosure plate 619. However, in the process of moving the opposite side shell plate 2, the second slide bar 87 will slide from the inner side of the connecting groove 5 13 to the inner side of the connecting groove 4 12, and at this time, the second slide bar 87 will slide from the inner side of the connecting groove 5 13 to the inner side of the connecting groove 4 12. The slide bar 87 drives the second connecting cylinder 88 to move upward, and at the same time, the lifting plate 89 moves upward and passes between the two sets of second connecting plates 624. At this time, the spring 810 will expand. When the second sliding rod 87 moves to the inner side of the connecting groove 3 11, the second connecting cylinder 88 continues to move backward and passes between the two sets of second arc plates 623 with the push of the first cylinder 61, so that the lifting plate 89 moves into the first arc plate 621. At the same time, when the connecting box 66 moves backward with the side shell plate 2, the first tooth plate 69 will be driven to move backward at the same time. When the lifting plate 89 is about to enter the inner side of the first arc plate 621, the first tooth plate 69 begins to mesh with the gear 611, and prompts the second tooth plate 612 to move, and then the moving rod 613 and the moving Under the connection of the third plate 616, the push plate 617 pushes the top cover 3 inside it to move in the direction of the first arc plate 621 at the same time. At this time, the top cover 3 and the lifting plate 89 are close to each other. Finally, when the lifting plate 89 moves into the inner side of the first arc plate 621, the top cover 3 is pushed to the upper end of the lifting plate 89 by the push plate 617. Next, the second cylinder 83 is started. The output end of the second cylinder 83 pushes the rotating plate 2 85 to move downward. When the rotating plate 2 85 moves downward, it contacts with the top cover 3 and pushes the top cover 3 and the lifting plate 89 to move downward. At this time, the second sliding rod 87 slides downward on the inner side of the connecting groove 2 10, and the spring 810 is compressed by force until the lower end of the top cover 3 contacts with the side shell plate 2. At this time, the side shell plate 2 and the top cover 3 can be welded. The second cylinder 83 is started. The motor 74 is driven by the second motor 74, and an instruction is set for the second motor 74, so that the second motor 74 drives the threaded rod 71 to rotate back and forth. When the threaded rod 71 starts to rotate, the connecting block 75 is moved through the screw principle under the cooperation with the connecting rod 72, thereby driving the welding gun 76 to move in the direction of the glass window 4. During this process, the first sliding bar 716 will continue to slide on the inner side of the slide rail 1 712, so that the cleaning brush 720 is in contact with the side shell plate 2 and the top cover 3, and the side of the side shell plate 2 and the top cover 3 to be welded is cleaned, and the side continues to move with the welding gun 76. After the cleaning brush 720 cleans the side of the side shell plate 2 and the top cover 3, the first sliding bar 716 will move into the inner side of the second slide rail 713, and prompt the lever 78 to rotate, so that the cleaning brush 720 is offset backward.Then, the scraper 722 is deflected forward to contact the side shell plate 2 and the top cover 3, and then the threaded rod 71 starts to rotate in the opposite direction under the impetus of the second motor 74, so that the welding gun 76 starts to move away from the glass window 4, and at the same time, the welding gun 76 is started to start welding the first surface of the side shell plate 2 and the top cover 3. The scraper 722 follows the movement of the welding gun 76 and scrapes off the welding slag on the surface of the side shell plate 2 and the top cover 3 after welding. At this time, the first sliding bar 716 is slidably connected to the inner side of the sliding rail 3 714, and the welding gun 76 moves to weld one side of the side shell plate 2 and the top cover 3. After the connection is completed, the first slide bar 716 will slide back into the slide rail 1 712 through the slide rail 4 715. During the process, the lever 78 will rotate back again, so that the scraper 722 will deflect backward to its original position, and the cleaning brush 720 will continue to deflect forward. Then the first motor 67 drives the rotating plate 1 68 to rotate, and rotates the side shell plate 2 and the top cover 3 under the clamping of the lifting plate 89 and the rotating plate 2 85, so that the next side of the side shell plate 2 and the top cover 3 to be welded is moved to one side of the welding gun 76, and the above steps are repeated until the four contacting surfaces of the side shell plate 2 and the top cover 3 are all welded. After the welding is completed, , the second cylinder 83 is started again to shrink. At this time, the lifting plate 89 and the spring 810 lose pressure, which prompts the lifting plate 89 to move upward to the inner side of the first arc plate 621 with the welded side shell plate 2 and the top cover 3. Then the first cylinder 61 is started again to shrink it. Under the connection of the moving plate 1 62, the lifting plate 89 carries the welded side shell plate 2 and the top cover 3 and moves forward. During the process, the welded side shell plate 2 and the top cover 3 will move to the two sets of connecting plates 2 624. In addition, the first tooth plate 69 is meshed with the gear 611 again to prompt the push plate 617 to move back to the lower end of the storage box 618. The next set of top covers 3 to be welded continues to fall into the inner side of the push plate 617, and then when the second slide bar 87 slides from the inner side of the connection groove 3 11 to the inner side of the connection groove 4 12, the lifting plate 89 moves downward, moves out from under the welded side shell plate 2 and top cover 3, and passes through between the two sets of connection plates 2 624 again, until the second slide bar 87 slides into the inner side of the connection groove 5 13 as it moves forward, so that the support plate 627 and the lifting plate 89 return to their original positions. At this time, the welded side shell plate 2 and top cover 3 stay at the upper end of the two sets of connection plates 2 624, which is convenient for the staff to carry out the next step.
