[0060] Another technical problem to be solved by the present invention is to provide a punching method of a photovoltaic inverter profile punching device, comprising the following steps:

[0061] S1. Workpiece clamping

[0062] Place the two ends of the profile to be punched into the two placement plates 45, and control the pressing plate 46 to press down to fix the two ends of the profile to form a clamping effect. In the subsequent processing, the clamping mechanism 4 can also be used to control the profile to move forward, backward, left and right, so as to quickly punch different areas on the profile;

[0063] S2, Punching model adjustment

[0064] The first mounting plate 34 and the second mounting plate 398 are rotated according to the punching size model, so that the punching head 381 facing directly downward on the first mounting plate 34 and the punching base plate 36 directly above the second mounting plate 398 can match the model requirements of the punching processing, and then the punching head 381 punches downward to perform punching;

[0065] S3. Debris treatment

[0066] During the punching process in step S2, the debris punched by the punch head 381 directly enters the chip groove 38 through the punching hole 37, and is directly discharged into the cabinet 1 through the chip groove 38 for accumulation. After opening the door panel 367, the debris inside the cabinet 1 can be centrally processed to avoid the debris scattering and causing troublesome cleaning.

[0067] In the actual operation process, firstly, the device is powered on, and after the bidirectional threaded rod 49 is rotated, the bidirectional threaded rod 49 drives the two connecting plates 48 to move towards or away from each other, and the connecting plate 48 drives the placement frame to move, so as to match profiles of different lengths and sizes.

It can be seen from the above connection relationship that the position of the profile can be quickly adjusted by adjusting the left and right movement of the frame 43 and the front and back movement of the movable seat 41, so that punching processing can be performed at different positions, the operation is flexible, and the punching efficiency is guaranteed;

[0068] Before the punching operation, the punching heads 381 and punching base plates 36 of different sizes to be used can be selected. After the numbers are selected, the punching heads 381 and punching base plates 36 are inserted and placed in the second placement cavity 399 and the first placement cavity 35 in sequence. After placement, the first threaded adjustment rod 364 and the second threaded adjustment rod 365 are rotated, and the first threaded adjustment rod 364 and the second threaded adjustment rod 365 respectively drive the first plug plate 387 and the second plug plate 388 to move until the first plug plate 387 is inserted into the first slot 389 and the second plug plate 388 is inserted into the second slot 371, and the installation and fixation of the punching head 381 and the punching base plate 36 are completed;

[0069] During processing, when it is necessary to switch different punching base plates 36, the first motor 392 works and drives the first gear 393 to rotate, the first gear 393 drives the second gear 394 to rotate, the second gear 394 drives the first round rod 33 to rotate, the first round rod 33 drives the first mounting plate 34 to rotate, when the corresponding punching base plate 36 on the first mounting plate 34 is directly above, the first electric push rod 391 works and pushes the cross plate 39 upwards, the cross plate 39 drives the lifting plate 32 to move, the lifting plate 32 drives the first round rod 33 to move, the first round rod 33 drives the first mounting plate 34 to move, and the first After the mounting plate 34 drives the top punching base plate 36 to move to extend outside the cabinet 1, the adjustment is completed. Similarly, when the punching base plate 36 needs to be replaced, it is necessary to first control the top punching base plate 36 to enter the cabinet 1 before the first mounting plate 34 can be controlled to rotate and continue to adjust. After the adjustment is completed, the second electric push rod 379 works and pushes the first positioning plate 373. After the first positioning plate 373 moves to the first positioning groove 374 on the insertion side, the first positioning plate 373 provides a limit for the first mounting plate 34, which can improve the stability of the first mounting plate 34 during the punching operation.

[0070] After the punching base plate 36 is adjusted, the second motor 382 works and drives the third gear 383 to rotate, the third gear 383 drives the fourth gear 384 to rotate, the fourth gear 384 drives the second round rod 397 to rotate, and the second round rod 397 drives the second mounting plate 398 to rotate. It can be seen from the above connection relationship that the position of the punch head 381 can be adjusted in this way. When the punch head 381 of the corresponding model is directly below, the adjustment is completed. Then the third electric push rod 362 works and pushes the adjustment block 361. After the adjustment block 361 moves, it drives the push rod 363 to flip. After the push rod 363 flips, the slider 377 The slider 377 is pushed to drive the second positioning plate 378 to move, until the second positioning plate 378 moves to be inserted into the second positioning groove 375 and then limits the second mounting plate 398. At this time, the second mounting plate 398 cannot rotate, which effectively ensures the stability of the second mounting plate 398 during the punching process. When the punch head 381 is adjusted, the cylinder 396 works to push the U-shaped plate 395, and the U-shaped plate 395 drives the second round rod 397 to move, and the second round rod 397 drives the second mounting plate 398 to move. The second mounting plate 398 drives the punch head 381 to move downward quickly to perform punching processing on the profile.

[0071] Finally, during the punching process, the debris punched by the punch head 381 directly enters the chip groove 38 through the punching hole 37, and is directly discharged into the cabinet 1 through the chip groove 38 for accumulation. When the debris needs to be cleaned up uniformly, the user can open the door panel 367 for quick processing. Compared with the debris falling everywhere during processing, cleaning is more convenient, which improves the convenience of processing.

[0072] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
