[0012] Optionally, the flipping assembly includes a second stepper motor, a transmission rod and a turntable. The second stepper motor is fixed on the lifting rod. The output end of the second stepper motor is connected to the transmission rod. The transmission rod passes through a through hole reserved on the lifting rod to connect to the turntable on the other side. The turntable is located directly above the conveyor belt.

[0013] Optionally, the automatic collection assembly includes a guide rod and a collection box, the guide rod is arranged on the mounting frame and is slightly higher than the conveyor belt, and the collection box is provided on the workbench below the guide rod.

[0014] Compared with the prior art, the advantages and positive effects of the present invention are:

[0015] 1. In the present invention, the explosion-proof patch is placed on a conveyor belt, and the power component drives the conveyor belt to transport the explosion-proof patch to the bottom of the detection unit for detection. After all the contents on the front of the explosion-proof patch are detected, the conveyor belt transports the explosion-proof patch to the bottom of the flip assembly. At the same time, the lifting assembly adjusts the height of the lifting rod, thereby adjusting the height of the flip assembly so that the flip assembly can flip the explosion-proof patch. After the flip is completed, the conveyor belt transports the explosion-proof patch to the bottom of the detection unit for re-detection, so that the front and back sides of the explosion-proof patch can be automatically detected, thereby improving the detection efficiency and reducing the detection cost.

[0016] 2. In the present invention, the first stepper motor drives the output shaft to rotate, and the output shaft and the transmission shaft are connected by a transmission belt. Therefore, the output shaft can transmit power to the transmission shaft, thereby realizing power transmission, and then driving the transmission shaft to rotate. The transmission shaft is connected to the input end of the conveyor belt, so the first stepper motor can drive the conveyor belt to transport the explosion-proof patch, thereby realizing the function of driving the transmission belt.

[0017] 3. In the present invention, the third stepper motor rotates the lead screw, which drives another lead screw to rotate through a synchronization component, so that the two lead screws can rotate synchronously to prevent the occurrence of rod jamming. The two lead screws rotate in the corresponding threaded holes to drive the lifting rod to move up and down.

[0018] 4. In the present invention, the two screw rods and sprockets are of the same size, and a chain is connected between the two sprockets. Therefore, when one screw rod is driven to rotate, the screw rod drives the sprocket to rotate, and the sprocket drives the other sprocket to rotate through the chain, thereby realizing the function of synchronous rotation of the two screw rods.

[0019] 5. In the present invention, the conveyor belt transports the explosion-proof patch to the bottom of the turntable, and at the same time the lifting assembly drives the lifting rod to descend so that the turntable can resist the explosion-proof patch below. The contact surface between the turntable and the explosion-proof patch has a certain degree of stickiness, so the second stepper motor drives the transmission rod to rotate, and the transmission rod drives the turntable to rotate. The turntable sticks to the explosion-proof patch and then rotates, so that the turntable can realize the flipping function.

[0020] 6. In the present invention, the conveyor belt transports the tested explosion-proof patches toward the side of the guide rod. The explosion-proof patches are blocked by the guide rod and gradually fall from the conveyor belt into the collection box below, thereby realizing the function of automatically collecting the explosion-proof patches.

[0031] In this embodiment, the explosion-proof patch is placed on the conveyor belt 4, and the power component drives the conveyor belt 4 to transport the explosion-proof patch to the bottom of the detection unit 10 for detection. After all the contents on the front of the explosion-proof patch are detected, the conveyor belt 4 transports the explosion-proof patch to the bottom of the flipping component. At the same time, the lifting component adjusts the height of the lifting rod 12, thereby adjusting the height of the flipping component so that the flipping component can flip the explosion-proof patch. After the flipping is completed, the conveyor belt 4 transports the explosion-proof patch to the bottom of the detection unit 10 for re-detection, so that the front and back sides of the explosion-proof patch can be automatically detected, thereby improving the detection efficiency and reducing the detection cost. After the front of the explosion-proof patch is completely detected, the automatic collection component cooperates with the conveyor belt 4 to collect the explosion-proof patch, thereby improving the detection efficiency and automation level of the explosion-proof patch detection device, and reducing the manpower cost required in the past, thereby greatly reducing the detection cost.

[0032] The power assembly includes a transmission shaft 5, a transmission belt 6, a first stepper motor 7 and an output shaft 8. The input end of the conveyor belt 4 is connected to the transmission shaft 5. The first stepper motor 7 is installed on the side of the workbench 1 close to the transmission shaft 5. The output shaft 8 of the first stepper motor 7 and the transmission shaft 5 are connected through the transmission belt 6.

[0033] In this embodiment, the first stepper motor 7 drives the output shaft 8 to rotate, and the output shaft 8 and the transmission shaft 5 are connected by a transmission belt 6, so the output shaft 8 can transmit power to the transmission shaft 5, thereby realizing power transmission, and then driving the transmission shaft 5 to rotate. The transmission shaft 5 is connected to the input end of the conveyor belt 4, so the first stepper motor 7 can drive the conveyor belt 4 to transport the explosion-proof patch, thereby realizing the function of driving the conveyor belt 4.

[0034] The lifting assembly includes a threaded hole 13, a screw rod 17 and a third stepper motor 21. Two threaded holes 13 are opened on the lifting rod 12. The third stepper motor 21 is fixedly installed on the inner bottom surface of the bracket 11. The output end of the third stepper motor 21 is connected upward to a screw rod 17, and another screw rod 17 is arranged parallel to the screw rod 17. A synchronization assembly is installed on the two screw rods 17. The two screw rods 17 are inserted into the corresponding threaded holes 13 and threadedly connected.

[0035] In this embodiment, the screw rod 17 and the threaded hole 13 are adapted to each other and threadedly connected. Therefore, the screw rod 17 is rotated by the third stepper motor 21, and the screw rod 17 drives the other screw rod 17 to rotate through the synchronization component, so that the two screw rods 17 can rotate synchronously to prevent the occurrence of the rod jamming phenomenon. The two screw rods 17 rotate in the corresponding threaded holes 13, which can drive the lifting rod 12 to rise and fall.

[0036] The synchronization component includes a chain 19 and a sprocket 20. A sprocket 20 is installed on the rod body of each of the two screw rods 17, and the two sprockets 20 are engaged with each other to connect a chain 19.

[0037] In this embodiment, the two screw rods 17 and the sprockets 20 are of the same size, and a chain 19 is connected between the two sprockets 20. Therefore, when one screw rod 17 is driven to rotate, the screw rod 17 drives the sprocket 20 to rotate, and the sprocket 20 drives the other sprocket 20 to rotate through the chain 19, thereby realizing the function of synchronous rotation of the two screw rods 17.

[0038] One end of the screw rod 17 on the third stepper motor 21 away from the third stepper motor 21 is inserted into the bearing seat 18 , and both ends of the other screw rod 17 are also inserted into the corresponding bearing seat 18 , and the bearing seat 18 is fixed on the bracket 11 .

The output end of the second stepper motor 14 is connected to the transmission rod 15. The transmission rod 15 passes through the through hole reserved on the lifting rod 12 to connect to the turntable 16 on the other side. The turntable 16 is located directly above the conveyor belt 4.

[0041] In this embodiment, the conveyor belt 4 transports the explosion-proof patch to the bottom of the turntable 16, and at the same time the lifting assembly drives the lifting rod 12 to descend, so that the turntable 16 can support the explosion-proof patch below. The contact surface between the turntable 16 and the explosion-proof patch has a certain degree of stickiness, so the second stepper motor 14 drives the transmission rod 15 to rotate, and the transmission rod 15 drives the turntable 16 to rotate. The turntable 16 sticks to the explosion-proof patch and then rotates, so that the turntable 16 can realize the flipping function.

It has higher precision in driving the conveyor belt 4, lifting assembly and flipping assembly, thereby improving the detection accuracy of the explosion-proof patch detection device.
