[0059] When the pressure rod 188 is riveted to the gasket on the fuse bracket, the hollow structure inside the pressure rod 188 is connected to the inside of the gasket. At this time, gas is supplied into the gasket, the top of the gasket is connected to the pressure rod 188, and the other end is blocked by the rivet seat. After the gas is supplied, the gas supply is stopped. The gas pressure sensor can monitor the sealing effect of the gasket, which can help detect the sealing effect of the gasket after the fuse bracket is installed.

[0060] A label box 19 is fixedly installed on one side of the top frame 18. A discharge port is opened at the bottom of the label box 19. Label rolls are stored in the label box 19. A tension roller 192 is rotatably installed below the label box 19. A baffle 191 is fixedly installed below the label box 19 and on the outside of the label. After the label paper passes through the discharge port, it is located in front of the baffle 191. The label taking operation is performed here. After the label is taken, the release paper is passed down through the tension roller 192 and then the remaining release paper is wound up by an electric winding mechanism. The electric winding mechanism includes a drive motor and a take-up roller. The drive motor controls the take-up roller to wind up the release paper and recycle waste.

[0061] Label removal is accomplished by label removal mechanism 3, which includes a horizontal slide table 30, a label transfer plate 31 that slides on the horizontal slide table 30, a cylinder 8 32 that is fixedly installed on the label transfer plate 31, and a label removal plate 33 that is fixedly connected to the output end of the cylinder 8 32. The label removal plate 33 has multiple suction nozzles that suck the label away from the release paper. Then, driven by the horizontal slide table 30, the label removal plate 33 is moved horizontally to one side of the riveting position. The label removal plate 33 is moved horizontally by the cylinder 8 32 to attach the label to the side of the product.

[0062] like Figure 9 As shown, a drive screw 41 is provided inside the equipment cabinet 1 and below the discharge port 100. A control motor is fixedly connected to the end of the drive screw 41.

[0063] A conveyor belt 4 is fixedly installed on one side of the feeding plate 46. When the feeding plate 46 is tilted, the fuse bracket slides from the feeding plate 46 onto the conveyor belt 4 for material discharge control. The fuse bracket riveted on the conveyor belt 4 is sent to the sorting rack 5. A lifting frame 51 is fixedly installed on the sorting rack 5. A hopper 52 is slidably installed on the lifting frame 51. During air tightness testing, the quality of the riveted product is determined by a sensor. The lifting frame 51 controls the lifting of the hopper 52 to classify and discharge finished products and defective products to discharge positions at different heights.

[0064] In this embodiment, the pad is clamped by the pneumatic clamp 183 and adjusted to be placed on the rivet base. Then, the jig plate 21 moves towards the conveyor belt 11. The transfer rack 14 adsorbs the fuse bracket and moves it to be placed on the jig plate 21. At this time, the installation position on the fuse bracket corresponds to the pad. Then, the jig plate 21 is moved to the riveting position below the top frame 18. At this position, the pressure rod 188 moves downward to press down and fix the fuse bracket. Then, the top cylinder 23 pushes the riveting column 22 upward to assemble the pad and the fuse bracket.

[0065] After the fuse holder is riveted to the pad on the rivet seat, an airtightness test is performed. At this time, the labeling operation can be performed. After the test, the fixture plate 21 moves to one side of the discharge port 100. First, the fuse holder is removed by the discharge rack 185 and moved into the tray 43 inside the discharge port 100. Then, the pad is fed onto the rivet seat. The finished fuse holder is moved to the sorting rack 5 by the conveyor belt 4 for sorting and discharge.
