[0024] The blanking device includes a blanking plate 21, one end of which is detachably connected to the punching machine 1, and the rear end of the blanking plate 21 is fixedly connected to the collecting box 3 by bolts;

[0025] A quality inspection mechanism 2 is provided on the blanking plate 21;

[0026] The quality inspection mechanism 2 includes a fixing frame 26 and a mounting frame 27. The fixing frame 26 is arranged at the lower end of the blanking plate 21. The lower end of the mounting frame 27 is symmetrically provided with an electromagnetic column rod 29. The mounting frame 27 is arranged at the lower end of the driving component 5. The blanking plate 21 is provided with a rectangular groove. One end of the fixing frame 26 is provided with a limit block 23. The limit block 23 is movably connected with the rectangular groove. The blanking plate 21 is symmetrically provided with positioning holes 22. The upper end of the fixing frame 26 is provided with a reset component. The reset component It includes an oil pressure damper 25 installed on the upper end of the fixing frame 26 and a spring 24 sleeved on the outside of the oil pressure damper 25. The upper ends of the spring 24 and the oil pressure damper 25 are connected to the lower end of the unloading plate 21, and the lower end of the spring 24 is connected to the upper end of the fixing frame 26. The lower end of the mounting frame 27 is symmetrically equipped with positioning columns 28, and the positioning columns 28 are adapted to the positioning holes 22. A waste box 4 is arranged on one side of the collecting box 3, and a guide plate 6 is installed at the front end of the waste box 4.

[0027] Specifically, a guide plate is symmetrically installed above the blanking plate 21, and the guide plate is adapted to the specifications of the workpiece. The workpiece slides downward along the blanking plate 21 until it is blocked by the limit block 23. The limit block 23 is installed with the fixing frame 26 and movably interlaced with the rectangular groove. After the electromagnetic column 29 at the lower end of the mounting frame 27 is plugged into the opening of the purlin support plate, the positioning column 28 will simultaneously be plugged into the positioning hole 22 and press the fixing frame 26 downward. At this time, the oil pressure damper 25 extends a certain distance. After the cylinder 55 quickly retracts the mounting frame 27, the spring 24 is slowly reset by the influence of the oil pressure damper 25. During the reset process, the purlin support plate workpiece slides into the inside of the collecting box 3. After the limit block 23 is reset, it continues to limit and block the new workpiece.

[0028] It should be noted that the electromagnetic column rod 29 can be detachably mounted below the mounting frame 27, and the electromagnetic column rod 29 can be replaced with a suitable specification according to the size of the opening of the workpiece.

[0029] The driving assembly 5 includes a rail frame 51 installed on the side of the waste bin 4 and a servo motor 52 arranged at the rear end of the rail frame 51. A threaded rod is installed inside the rail frame 51. A slider 53 is threadedly inserted through the threaded rod. A cylinder 55 is installed at the lower end of the slider 53. The telescopic end of the cylinder 55 is installed at the upper end of the mounting frame 27. A battery 54 is installed at the upper end of the slider 53.

The servo motor 52 is installed at the upper tail end of the rail frame 51. The threaded rod installed inside the rail frame 51 is connected to the output end of the servo motor 52. The slider 53 is threadedly sleeved with the threaded rod. When the servo motor 52 is started, it will rotate with the threaded rod, so that the slider 53 moves laterally along the rail frame 51. The position of the cylinder 55 can be adjusted by the lateral movement.

[0031] Furthermore, after the electromagnetic rod 29 cannot be inserted into the opening of the purlin support plate, the limit block 23 cannot move downward, and the battery 54 energizes the electromagnetic rod 29 to magnetically attract the inferior purlin support plate, and adsorbs the purlin support plate to the guide plate 6 through the slider 53. After the battery 54 is powered off, the inferior purlin support plate is no longer adsorbed and slides from the guide plate 6 into the waste box 4.

[0032] When in use, by setting up the quality inspection mechanism 2, a rail frame 51 is installed on one side of the waste box 4, and the slider 53 and the cylinder 55 that are movable on the rail frame 51 are used to drive the threaded rod to rotate by the servo motor 52, so as to adjust the lateral movement of the mounting frame 27. When the mounting frame 27 is located directly above the blanking plate 21, the cylinder 55 drives the telescopic shaft to approach the purlin support plate. After the electromagnetic column rod 29 is plugged into the opening of the purlin support plate, it indicates that the opening of the purlin support plate is correct. At this time, the positioning column rod 28 is plugged into the positioning hole 22 and the fixing frame 26 is further squeezed downward until the limit block 23 is squeezed downward from the rectangular groove. At this time, the limit block 23 no longer presses the purlin. The support plate is limited, and the cylinder 55 quickly retracts the mounting frame 27. The purlin support plate is no longer restricted and slides into the collection box 3. On the contrary, the electromagnetic column rod 29 cannot be inserted into the opening of the purlin support plate, and the limit block 23 cannot move downward. The battery 54 energizes the electromagnetic column rod 29 to magnetically attract the inferior purlin support plate, and adsorbs the purlin support plate to the guide plate 6 through the slider 53. After the battery 54 is powered off, the inferior purlin support plate is no longer adsorbed and slides from the guide plate 6 to the waste box 4. Through this unloading method, the quality of the product opening is inspected during the unloading process, which reduces the labor intensity of the staff and improves the production efficiency of the product.
