A screw rod 405 is arranged inside the fixed bearing 404, and a moving plate 406 is threadedly connected to the outer wall of the screw rod 405. A threaded hole 407 is opened on the outer wall of the moving plate 406, and a round rod 408 is fixedly connected to the outer wall of the moving plate 406. One end of the round rod 408 is fixedly connected to a support foot 409.

[0025] Through the above technical solution, by the operation of the deceleration motor 203, the moving block 205 can be moved. The moving block 205 drives the support plate 207 to move, so that the placement plate 208 can move out of the detection box 1. The operator transports and places the workpiece 5 on the placement plate 208. By the operation of the deceleration motor 203, the placement plate 208 drives the workpiece 5 to move back into the detection box 1, making the process of feeding the vulcanization capsule workpiece 5 into the detection box 1 faster and more efficient, meeting people's needs.

The atmospheric pressure intelligent sensor 8 can sense the pressure inside the detection box 1. A controller is arranged on one side of the detection box 1. The base 201 is fixed at the inner bottom of the detection box 1, and multiple connection blocks 401 are fixed on both sides of the detection box 1.

[0028] Specifically, the reduction motor 203 and the moving block 205 form a moving structure through the lead screw 204, and one end of the lead screw 204 threadedly penetrates through the thread groove 206.

[0029] Through the above technical solution, the connection effect between the reduction motor 203, the lead screw 204 and the moving block 205 is strengthened. A bearing is provided at one end of the lead screw 204, and the bearing is fixed in the chute 202 of the base 201. When the lead screw 204 rotates, it rotates more stably by relying on the bearing.

[0030] Specifically, the inner wall shape and size of the chute 202 match the outer wall shape and size of the moving block 205, and the inner wall of the chute 202 is in contact with the outer wall of the moving block 205.

[0031] Through the above technical solution, the connection effect between the chute 202 and the moving block 205 is strengthened. When the moving block 205 moves, it moves more stably in the chute 202.

[0032] Specifically, the number of the placing plates 208 is multiple, and the multiple placing plates 208 are arranged at equal intervals on the supporting plate 207.

[0033] Through the above technical solution, by providing multiple placing plates 208, it is convenient to place the workpiece 5.

[0034] Specifically, the moving plate 406 and the screw rod 405 form a threaded structure through the threaded hole 407, and one end of the screw rod 405 threadedly penetrates through the threaded hole 407.

[0035] Through the above technical solution, the connection effect between the moving plate 406, the threaded hole 407 and the screw rod 405 is strengthened.

[0037] Through the above technical solution, the connection effect between the moving plate 406 and the long groove 403 is strengthened. When the moving plate 406 moves, it moves more stably in the long groove 403.

[0038] In use, first connect an external power supply to this device, and the external power supply powers this device. This device relies on the universal wheels 3 to move to the designated position. When parking, the operator rotates the screw rod 405 to make the moving plate 406 move more stably in the long groove 403. The moving plate 406 drives the round rod 408 to move downward, and the round rod 408 drives the support feet 409 to move downward to contact the ground. Through the four support feet 409 contacting the ground, the anti-slip force is enhanced, making this device park more stably. When detecting the workpiece 5, the operator opens the sealing door 12. By the operation of the reduction motor 203, the lead screw 204 rotates, thereby making the moving block 205 move. The moving block 205 moves more stably in the chute 202. The moving block 205 drives the support plate 207 to move, and the support plate 207 drives the placement plate 208 to move. The placement plate 208 moves out of the detection box 1 to the outside. The operator places the vulcanized capsule workpiece 5 to be detected on the placement plate 208. By the operation of the reduction motor 203, the moving block 205 moves, making the placement plate 208 drive the workpiece 5 to move back into the detection box 1. Then close the sealing door 12. The vacuum pump 9 works to pump out the air in the detection box 1. When the detection box 1 is in a vacuum state, the electric push rod 10 works to push the sealing plate 11 to block the hole of the air extraction pipe of the vacuum pump 9, and the vacuum pump 9 stops working. The hydraulic cylinder 6 works to drive the pressing plate 7 to move downward to press the vulcanized capsule workpiece 5, and press it back and forth several times, pressing for three to six seconds each time. According to the pressure change value detected by the atmospheric pressure intelligent sensor 8, it is judged whether the tire is leaking air. After the detection is completed, the hydraulic cylinder 6 works to drive the pressing plate 7 to move upward, and the hydraulic cylinder 6 stops working. The operator opens the sealing door 12, and the reduction motor 203 works to make the placement plate 208 drive the workpiece 5 to move out of the detection box 1. The operator takes away the workpiece 5, and thus all the work is completed. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.
