[0024] Furthermore, the C-shaped structural frame 22 is a C-shaped rectangular frame, and the base portion of the C-shaped structural frame 22 is a flat rectangular plate.

[0025] Here’s how this application works: After manually pouring enough prepared materials into the vibration plate 7, the power supply can be turned on. The vibration plate 7 will climb forward along the spiral guide groove. The guide groove has screening parts or mechanisms to promote the incoming materials to move in the correct posture, while the workpieces with incorrect directions or postures will be guided out of the guide groove and fall back into the vibration plate 7. The workpieces that fall back into the vibration plate 7 can be output after the posture is corrected by the next vibration conveying. Through continuous posture guidance and screening, the workpieces are continuously output in the correct posture.

[0026] A detection switch is set at the end of the vibration plate 7. The system will only proceed to the next step of grabbing and moving when the detection switch feedbacks that there is material. There is also a detection switch on the material channel. When there is no material on the material channel for a long time, the system will have a lack of material reminder.

[0027] The function of the lead seal tooling is: the vibration plate 7 automatically feeds the lead seal into the lower die seat, the lower die seat is equipped with a sensor, when the lead seal reaches the predetermined position, the push rod cylinder 20 pushes the workpiece into the stamping position, and after the stamping is completed, the push rod cylinder 20 pushes the workpiece into the bending mechanism.

[0028] The C-frame is equipped with an electric cylinder 23 and a pressure sensor, and the punch seat 24 is used to punch the workpiece from top to bottom. The rotary drive of the above mechanism adopts an absolute value servo drive, and cooperates with a reducer and a rolling shaft for forming to complete the station rolling forming process. The rotary mechanism is installed on the rear side of the forming panel and is supported by a slide cylinder. The above finished product storage is that the system records the number once each forming and bending is performed. When the number reaches a certain number, the system prompts manual recycling of the product. After recycling the products in the material box 10, put it back into the empty box. The counted number can also be cleared at any time.

[0029] Beneficial effects of the present invention: 1. High degree of automation. The technology of this application introduces the vibration of the vibration plate to feed the material, and through the function of the automation component, the automatic forming of the lead seal is realized. Except for the manual replenishment of the lead seal and the replacement of the punch, the rest of the process is completed by the machine, with a high degree of automation.

[0030] 2. High repeatability. The lead seal forming technology provided in this application performs stamping and bending actions at a fixed position each time, and the lead seal sheets produced by the equipment have high repeatability and reliable quality.

[0031] 2. High production efficiency. The lead seal automatic molding technology provided by this application makes the equipment production rhythm designed according to the 3-second molding time of each lead seal, and there is no long pause during the feeding production process. In this way, the production cycle is reduced and the production efficiency is greatly improved.
