[0035] As a preferred embodiment, the telescopic oil cylinder 53 is composed of an oil barrel 531 and a movable slide rod 532. The oil barrel 531 is fixedly installed on the extended end of the support frame 51. The movable slide rod 532 is sealed and slidably arranged in the oil barrel 531, and the movable slide rod 532 slides through the extended end of the support frame 51. An oil inlet hole 533 is opened on the side wall of the oil barrel 531, and the oil inlet hole 533 is connected to an external oil storage tank through a connecting hose.

[0036] The oil output or oil inlet of the external oil storage tank is controlled by the operating console 2 so as to adjust the extension length of the movable slide rod 532 .

[0037] In addition, a rubber layer is provided on the inner wall of the oil cylinder 531 , so the movable slide rod 532 needs to overcome the friction between the rubber layer during the up and down movement.

[0038] As a preferred embodiment, the four guide heads 56 are hingedly provided with connecting tubes 561, and four sliding rods 562 are respectively slidably provided in the four connecting tubes 561, and the ends of the four sliding rods 562 away from the connecting tubes 561 are hingedly provided on the movable sliding rod 532.

[0039] Please refer to the following for details: Figure 5 When the movable slide rod 532 moves up and down, it will drive the guide head 56 to turn through the sliding rod 562 and the connecting pipe 561.

[0040] As a preferred embodiment, the expansion unit 55 includes a touch rod 61, an arc plate 62, a connecting rod 1 63, a connecting rod 2 64 and a buckle 65; a built-in groove is provided in the lower end of the movable slide 532, the touch rod 61 is slidably arranged in the built-in groove, and a self-locking switch is provided between the touch rod 61 and the inner wall of the built-in groove, the arc plate 62 is provided with at least two, and is symmetrically arranged, respectively arranged on the outer periphery of the touch rod 61, and a guide groove 62 is provided on the inner wall of the upper end of the arc plate 62 1. A slider is slidably provided in the guide groove 621, and a rubber pad is bonded to the outer wall of the curved plate 62. The connecting rod 1 63 is provided with two, one end of which is hingedly provided on the side wall of the movable slide rod 532, and the other end is hingedly provided on the lower end of the two curved plates 62. The connecting rod 2 64 is provided with two, one end of which is hingedly provided on the side wall of the touch rod 61, and the other end is hingedly provided on the two sliders. The buckle 65 rotates through the connecting rod 1 63 and the connecting rod 2 64.

[0041] It should be explained that the self-locking switch described above is a mechanical self-locking switch, which is stuck when the touch rod 61 is squeezed for the first time and bounces back when the touch rod 61 is squeezed for the second time. The principle and structure of the mechanical self-locking switch are all existing technologies and will not be elaborated here.

[0042] Please refer to the following for details: Figure 6 When the telescopic cylinder 53 is extended, the movable slide rod 532 drives the touch rod 61 to move downward synchronously. When the touch rod 61 and the glass turntable 3 produce an extrusion effect, the touch rod 61 will move toward the inside of the built-in groove, and the two arc-shaped plates 62 will expand outward. The two rubber pads will contact and squeeze the inner wall of the product to be inspected. When the inner wall of the product to be inspected is fully supported by the rubber pads, the touch rod 61 is stuck, and then the telescopic cylinder 53 is contracted. The friction between the two rubber pads and the inner wall of the product can drive the product to move upward synchronously with the movable slide rod 532.

[0043] In addition, it should be noted that when the movable slide bar 532 moves downward, the movable slide bar 532 will drive the guide head 56 and the camera body 57 to rotate downward through the sliding bar 562 and the connecting tube 561. When the touch bar 61 is stuck, the camera body 57 is just facing the upper edge of the product. When the movable slide bar 532 moves upward, the movable slide bar 532 will drive the guide head 56 and the camera body 57 to rotate upward through the sliding bar 562 and the connecting tube 561. When the movable slide bar 532 moves up to the highest point, the camera body 57 is just facing the lower edge of the product. During the upward movement of the product, the camera body 57 can take a complete picture of the product from bottom to top, and can also take pictures of a certain area at different angles. That is to say, if reflection occurs when photographing a certain area of ​​the product, the images taken at other angles can be used as substitutes for the images of this area to prevent the image of this area from being lost, so that the clarity of the captured images of the product can be unified, thereby improving the detection accuracy.

[0044] After the inspection is completed, the movable slide bar 532 moves down. When the touch rod 61 is squeezed with the glass turntable 3 again, the touch rod 61 rebounds and the two rubber pads are separated from the inner wall of the product. Then the touch rod 61 and the movable slide bar 532 move up to complete one inspection.

[0045] As a preferred embodiment, the guide unit 58 includes a connecting disk 1 71, a connecting disk 2 72, a fixed tube 73, a T-shaped slide bar 1 74, a spherical head 1 75 and a spring 1 76; the connecting disk 1 71 is fixedly mounted on the guide head 56, the connecting disk 2 72 is fixedly mounted on the camera body 57, a spherical groove 1 is provided at the center of the connecting disk 2 72, the fixed tube 73 is fixed at the center of the connecting disk 1 71, a retaining ring 1 731 is fixed at one end of the fixed tube 73 away from the connecting disk 1 71, the T-shaped slide bar 1 74 is sealingly slidably penetrated in the fixed tube 73, and the T-shaped slide bar 1 74 is in sealing and movable contact with the inner wall of the retaining ring 1 731, the spherical head 1 75 is fixed at one end of the T-shaped slide bar 1 74 away from the fixed tube 73, and the spherical head 1 75 is arranged in the spherical groove 1, and the spring 1 76 is connected between the spherical head 1 75 and the inner wall of the spherical groove 1.

[0046] The function of the snap ring 731 is to prevent the T-shaped slide bar 74 from sliding out of the fixing tube 73 .

[0047] As a preferred embodiment, the guide unit 58 also includes a stopper 81, a T-shaped block 82, a guide cylinder 83, a T-shaped slide rod 2 84, a spherical head 2 85, a sealing ring 86, a spring 2 87 and a spring 3 88; the eccentric side of the connecting disk 1 71 is provided with a T-shaped ring groove 711, the stopper 81 is fixed in the T-shaped ring groove 711, the T-shaped block 82 is sealingly slidably arranged in the T-shaped ring groove 711, the guide cylinder 83 is fixed on the T-shaped block 82, and an L-shaped flow channel 821 is provided in the T-shaped block 82, one end of the L-shaped flow channel 821 is connected to the guide cylinder 83, and the other end is connected to the T-shaped ring groove 711 on the side of the stopper 81, the T-shaped slide rod 2 84 is sealingly slidably arranged in the guide cylinder 83, and the guide cylinder 83 A second snap ring 831 is fixed to the end away from the connecting disk 1 71, and the T-shaped slide bar 2 84 is in sealing and movable contact with the second snap ring 831. A limiting ring groove 721 is provided on the eccentric side of the connecting disk 2 72. The second spherical head 85 is fixed to the end of the T-shaped slide bar 2 84 away from the guide cylinder 83, and the second spherical head 85 is in movable contact with the inner wall of the limiting ring groove 721. The blocking ring 86 is fixed on the guide cylinder 83, and the blocking ring 86 is in sealing and movable contact with the side wall of the connecting disk 1 71. There are two springs 2 87, one of which is connected between the T-shaped slide bar 1 74 and the inner wall of the fixed cylinder 73, and the other is connected between the T-shaped slide bar 2 84 and the inner wall of the guide cylinder 83. The third spring 88 is connected between the stop block 81 and the T-shaped block 82.

[0048] Among them, like the function of the first snap ring 731, the second snap ring 831 can prevent the second T-shaped slide bar 84 from sliding out of the guide cylinder 83.

[0049] In addition, the first and second snap rings 731 and 831 are respectively provided with an air guide hole 1 732 and an air guide hole 2 832 . The air guide hole 1 732 and the air guide hole 2 832 can prevent pressure from being generated in the gaps between the first and second T-shaped slide bars 74 and 84 and the fixing tube 73 and the guide tube 83 respectively.

[0050] In the above description, a closed space is formed between the sealing ring 86 , the stopper 81 and the T-shaped block 82 . That is, when positive pressure is generated in the closed space, the T-shaped block 82 will drive the guide cylinder 83 to slide along the T-shaped ring groove 711 .

[0051] As a preferred embodiment, a connecting hole is opened on the side wall of the oil cylinder 531, and a micro solenoid valve 534 is arranged in the connecting hole. The connecting hole is connected to the four guide cylinders 83 through a tree-shaped hose 91, and the guide cylinder 83 in each guide unit 58 is connected to the fixed cylinder 73 through a connecting hose 92.

[0052] The micro solenoid valve 534 is controlled by the operating console 2 .

[0053] It should be noted that the elastic forces of the second spring 87 and the third spring 88 gradually increase, and the sum of the elastic forces of the above springs is smaller than the friction force between the movable slide bar 532 and the rubber layer.

[0054] Please refer to the following for details: Figures 7 to 12When the product moves upward with the movable slide 532, the real-time images captured by the four camera bodies 57 will be transmitted to the operating table 2. If there are defects such as dents or missing materials on the product, the control center of the operating table 2 will control the micro-solenoid valve 534 to open and gradually inject hydraulic oil into the oil cylinder 531 through the external oil storage tank. At this time, the tree-shaped hose 91 is connected to the oil cylinder 531, and the injected hydraulic oil will flow into the tree-shaped hose 91. There is a certain friction between the movable slide 532 and the rubber layer, so the movable slide 532 remains stationary. The hydraulic oil flowing into the tree-shaped hose 91 will first enter the closed space of the guide cylinder 83 and the T-shaped ring groove 711, and at the same time can flow into the fixed cylinder 73 through the connecting hose 92. When the hydraulic oil is fully filled, since the resistance of the spring 2 87 is less than that of the spring 3 88, the T-shaped slide 1 74 and the T-shaped slide 2 84 will move synchronously first, and the connecting disk 2 72 will drive the corresponding The camera body 57 is close to the product, so it can focus on and shoot the defect of the product, and capture the appearance of the defect more clearly, further improving the inspection accuracy of the product. When the T-shaped slide bar 1 74 is limited by the retaining ring 1 731, the T-shaped slide bar 2 84 continues to slide outward from the guide tube 83, so the connecting disk 2 72 and the camera body 57 will be tilted. When tilted to a certain angle, the T-shaped slide bar 2 84 is limited by the retaining ring 2 831, and the camera body 57 is tilted to the maximum angle. Thereafter, the pressure in the enclosed space of the T-shaped ring groove 711 increases. When this pressure is greater than the resistance of the spring 3 88, the T-shaped block 82 will drive the guide tube 83 to slide along the T-shaped ring groove 711. Therefore, under the squeezing action of the spherical head 2 85, the connecting disk 2 72 and the camera body 57 will perform a circular swinging motion, so that the camera body 57 can completely capture the internal appearance of the defect, thereby further improving the inspection accuracy of the product.

[0055] The use method and advantages of the present invention: The CCD full inspection machine for detecting product appearance has the following working process:

[0056] like Figures 1 to 12 As shown: first, the product to be inspected is introduced into the glass turntable 3 through the feeding module 41, and the optical fiber identification module 42 identifies the position of the product introduced into the glass turntable 3. Then, the product guide module 43 adjusts the product position so that each product is unified at a certain position. The products at the determined position will be photographed and inspected at the upper and lower ends of the product in turn by the upper camera module 44 and the lower camera module 45. Then, the products will be comprehensively inspected one by one by the all-round detection component 46.
