[0034] Refer to Figure 6 , the calibration mechanism 123 includes a support block 1231, a calibration component 1232 arranged on the support block 1231, and a driving motor 1233 for driving the calibration component 1232 to perform calibration.

[0035] Refer to Figure 1, the discharging assembly 130 includes a blanking manipulator 131 disposed on the calibration machine table 110 and a first conveyor belt 132 for receiving the products to be inspected and connecting with the feeding assembly 220. A material distribution assembly 133 is provided at the end of the first conveyor belt 132, and the material distribution assembly 133 is used to space each product to be inspected.

[0036] Refer to Figure 7 , the feeding assembly 220 includes a receiving base 221, a second conveyor belt 222 disposed on the receiving base 221 and connected to the material distribution assembly 133, and a first mechanical gripper 223 disposed on the receiving base 221 for clamping materials. A slideway is provided on the receiving base 221, and a slider for receiving the products to be inspected is provided on the slideway. A first driving cylinder 224 for driving the slider to receive materials is provided on the receiving base 221, and the first mechanical gripper 223 is disposed above the slideway.

[0037] Refer to Figure 8 , the material fetching and feeding assembly 230 includes a support platform 231 disposed on the side of the feeding assembly 220, a slide table 232 disposed on the support platform 231 and provided with a horizontally arranged first slide rail, a slide plate 233 slidably disposed on the slide table 232 and provided with a vertically arranged second slide rail, a support plate 234 slidably disposed on the second slide rail, a second driving cylinder 235 disposed on the support platform 231 for driving the slide plate 233 to slide left and right along the first slide rail, and a third driving cylinder disposed on the slide plate 233 for driving the support plate 234 to slide up and down along the second slide rail.

A third slide rail 253 is provided at the top of the fixed plate 252, and a material positioning mechanism 254 is slidably arranged on the third slide rail 253. A pushing block 255 is arranged at one end of the material positioning mechanism 254. Pulley wheels 256 are arranged at both ends of the fixed plate 252, and a belt 257 fixedly connected to the pushing block 255 is arranged on the two pulley wheels 256. A motor 258 for driving the belt 257 to drive the material positioning mechanism 254 to move is arranged on the fixed plate 252; a groove-shaped photoelectric switch 2520 is arranged at the bottom of the fixed plate 252, and the photoelectric switch 2520 is electrically connected to the motor 258); an induction block 2550 is arranged at the bottom of the pushing block 255. When the pushing block 255 moves into the groove of the photoelectric switch 2520, the photoelectric switch 2520 senses the induction block (2550), and the photoelectric switch 2520 controls the motor 258 to stop operating; the material positioning mechanism 254 includes a sliding base 2540 slidably arranged on the third slide rail 253 and a tightening component 2541 arranged on the sliding base 2540. The tightening component 2541 is composed of a group of oppositely arranged air cylinders. By arranging two oppositely arranged air cylinders, when the air cylinders operate, the piston rods of the two air cylinders tightly hold the product against each other, so that when the product moves in the material positioning mechanism 254, the product remains in a tightly held state, which is convenient for the testing component 240 to conduct detection.

[0039] Refer to Figure 10 , the material distributing mechanism 260 includes a material distribution channel 261. A good product channel and a defective product channel are provided on the material distribution channel 261. A baffle plate 262 is hinged on the material distribution channel 261. The baffle plate 262 is arranged between the good product channel and the defective product channel. A fourth driving air cylinder 263 for driving the baffle plate 262 to move and controlled by the control device 280 is arranged on the outer side wall of the material distribution channel 261. That is to say, when the tester 270 detects that the product is a good product, the second robotic gripper 236 grabs the product from the material positioning component 250 and directly sends it onto the material distribution channel 261. The tester 270 feeds back the detection information to the control device 280, and the control device 280 does not control the fourth driving air cylinder 263 to operate, so that the product flows out from the good product channel; when the detected product is a defective product, the second robotic gripper 236 grabs the product from the material positioning component 250 and directly sends it onto the material distribution channel 261. The tester 270 feeds back the detection information to the control device 280, and the control device 280 controls the fourth driving air cylinder 263 to operate. The fourth driving air cylinder 263 pushes the baffle plate 262 to block the good product channel, so that the defective product flows out from the defective product channel.

[0040] Working principle of the present invention: Start the feeding vibrating bowl 121. The product to be inspected is conveyed from the feeding channel of the feeding vibrating bowl 121 to the first channel in the base 1221 on the pushing mechanism 122. The first pushing cylinder 1222 pushes the first pushing block to push the product to be inspected to the calibration mechanism 123. The calibration mechanism 123 calibrates and shapes the product to be inspected. After calibration is completed, the second pushing cylinder 1223 pushes the second pushing block to push the product to be inspected after calibration into the second channel. The third pushing cylinder 1224 pushes the third pushing block to push the product to be inspected to the loading manipulator 124, and then the loading manipulator 124 grabs and places it on the fixture assembly 142 of the indexing turntable 140. At this time, start the cam divider assembly 141 to make the indexing turntable 140 rotate intermittently. When the product to be inspected reaches the position of the riveting assembly 150, stop the indexing turntable 140 from rotating, and the riveting assembly 150 rivets the product to be inspected. After riveting is completed, start the cam divider assembly 141 again to make the indexing turntable 140 rotate intermittently. When it reaches the position of the discharging assembly 130, the unloading manipulator 131 on the discharging assembly 130 grabs the product to be inspected and places the product to be inspected on the first conveyor belt 132. When the product to be inspected moves to the material distributing assembly 133, the material distributing assembly 133 rotates the product to be inspected by 90 degrees to achieve the interval of each product, and then the first conveyor belt 132 conveys the product to be inspected to the testing station 200.

[0041] When the product to be inspected is conveyed to the receiving base 221 through the second conveyor belt 222 on the feeding assembly 220, it is grasped by the first robotic gripper 223 and placed on the slider on the receiving base 221. Then, the first driving cylinder 224 pushes the slider to push the product to be inspected to the picking and feeding assembly 230. The second driving cylinder 235 on the picking and feeding assembly 230 drives the sliding plate 233 to move towards the slider, and at the same time, the sliding plate 233 drives the second robotic gripper 236 to move towards the slider. When the second robotic gripper 236 reaches above the slider, the third driving cylinder drives the support plate 234 to move downward, so that the second robotic gripper 236 can easily grasp the product to be inspected. After the second robotic gripper 236 grasps the product to be inspected, the third driving cylinder drives the support plate 234 to reset, and then the second driving cylinder 235 drives the sliding plate 233 to drive the second robotic gripper 236 to move towards the material positioning assembly 250. When the second robotic gripper 236 reaches above the material positioning assembly 250, the third driving cylinder drives the support plate 234 to move downward, and at the same time, the testing assembly 240 moves downward accordingly to detect the product to be inspected. At the same time, the material positioning mechanism 252 on the material positioning assembly 250 drives the movement through the belt 257, facilitating the testing assembly 240 to detect the entire product. After the detection is completed, the second robotic gripper 236 grasps the detected product and conveys it to the material sorting mechanism 260. When the tester 270 detects that the product is a good product, the second robotic gripper 236 directly grabs it from the material positioning assembly 250 and sends it to the sorting channel 261. The tester 270 feeds back the detection information to the control device 280, and the control device 280 does not control the operation of the fourth driving cylinder 263, so that the product flows out from the good product channel. When the detected product is a defective product, the second robotic gripper 236 directly grabs it from the material positioning assembly 250 and sends it to the sorting channel 261. The tester 270 feeds back the detection information to the control device 280, and the control device 280 controls the operation of the fourth driving cylinder 263. The fourth driving cylinder 263 pushes the baffle plate 262 to block the good product channel, so that the defective product flows out from the defective product channel.
