Detailed implementation manners

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 to 12 , the present invention provides a technical solution: a CCD full inspection machine for detecting the appearance of products, including a base 1, an operation table 2, a servo motor, a glass turntable 3 and a detection mechanism 4; the operation table 2 is fixed above the base 1 through square steel, the servo motor is fixedly installed at the center of the upper end of the base 1, the glass turntable 3 is fixed at the output end of the servo motor, the detection mechanism 4 is arranged on the base 1, the detection mechanism 4 is arranged along the periphery of the glass turntable 3, and successively includes a feeding module 41, a fiber optic identification module 42, a product guiding module 43, an upper camera module 44, a lower camera module 45, an omni-directional detection assembly 46 and an export module 47. Among them, the omni-directional detection assembly 46 is used for taking omni-directional photos of the products for detection.

[0020] Among them, a plurality of export modules 47 are configured, which are respectively used for classifying and exporting qualified products, repairable defective products and non-repairable defective products.

[0021] As a preferred embodiment, the all-round detection component 46 includes a support frame 51, a mounting frame 52, a telescopic oil cylinder 53, a mounting plate 54, an expansion unit 55, a guide head 56, a camera body 57 and a guiding unit 58; the support frame 51 is fixedly installed on the base 1, and an extension end is provided at the upper end of the support frame 51. Four mounting frames 52 are circumferentially arranged and are respectively fixed at the extension end of the support frame 51. The telescopic oil cylinder 53 is arranged at the extension end of the support frame 51. Four mounting plates 54 are provided and are respectively fixed at the lower ends of the four mounting frames 52. An annular mounting groove is formed on the side wall of the mounting frame 52. The expansion unit 55 is arranged at the output end of the telescopic oil cylinder 53. Four guide heads 56 are provided. An installation ring is fixed on one side of each of them. The four guide heads 56 are respectively rotationally arranged in the four annular mounting grooves through their installation rings. Four camera bodies 57 are provided and are respectively arranged on the mutually close sides of the four guide heads 56. Four guiding units 58 are provided and are respectively arranged between the guide heads 56 and the camera bodies 57.

[0022] Among them, the expansion unit 55 is used for internally clamping the product, and the guiding unit 58 is used for adjusting the shooting angle of the camera body 57.

[0023] As a preferred embodiment, the telescopic oil cylinder 53 is composed of an oil cylinder 531 and a movable sliding rod 532. The oil cylinder 531 is fixedly installed at the extension end of the support frame 51. The movable sliding rod 532 is hermetically and slidably arranged in the oil cylinder 531, and the movable sliding rod 532 slidably penetrates through the extension end of the support frame 51. An oil inlet hole 533 is formed on the side wall of the oil cylinder 531. The oil inlet hole 533 is communicated with an external oil storage tank through a connecting hose.

[0024] Among them, the external oil storage tank is controlled by the operation console 2 for its oil output or oil input amount to adjust the extension length of the movable sliding rod 532.

[0025] In addition, a rubber layer is provided on the inner wall of the oil cylinder 531. Therefore, the movable sliding rod 532 needs to overcome the friction force with the rubber layer during the up and down movement.

[0026] As a preferred embodiment, a connecting pipe 561 is hinged on the four guide heads 56. Four sliding rods 562 are respectively slidably penetrated in the four connecting pipes 561, and the ends of the four sliding rods 562 far away from the connecting pipes 561 are hinged on the movable sliding rod 532.

[0027] For details, please refer to Figure 5 , during the up and down movement of the movable sliding rod 532, the guide head 56 will be driven to turn through the sliding rod 562 and the connecting pipe 561.

[0028] As a preferred embodiment, the expansion unit 55 includes a touch rod 61, an arc-shaped plate 62, a first connecting rod 63, a second connecting rod 64 and a buckle 65; an internal groove is formed in the lower end of the movable slide rod 532, the touch rod 61 is slidably disposed through the internal groove, and a self-locking switch is disposed between the touch rod 61 and the inner wall of the internal groove. At least two arc-shaped plates 62 are provided and are symmetrically arranged, and are respectively disposed around the touch rod 61. A guide groove 621 is formed on the inner wall of the upper end of the arc-shaped plate 62, a slider is slidably disposed in the guide groove 621, and a rubber pad is bonded to the outer wall of the arc-shaped plate 62. Two first connecting rods 63 are provided, one end of each is respectively hinged to the side wall of the movable slide rod 532, and the other end of each is respectively hinged to the lower ends of the two arc-shaped plates 62. Two second connecting rods 64 are provided, one end of each is hinged to the side wall of the touch rod 61, and the other end of each is hinged to the two sliders. The buckle 65 rotatably penetrates through the first connecting rod 63 and the second connecting rod 64.

[0029] It should be noted that, as described above, the self-locking switch is a mechanical self-locking switch, which is stuck when the touch rod 61 is squeezed for the first time and rebounds when the touch rod 61 is squeezed for the second time. The principle and structure of the mechanical self-locking switch are both prior arts and will not be elaborated here.

[0030] For details, please refer to Figure 6 , when the telescopic oil cylinder 53 extends, the movable slide rod 532 drives the touch rod 61 to move downward synchronously. When the touch rod 61 exerts a squeezing action on the glass turntable 3, the touch rod 61 will move inward into the internal groove, and the two arc-shaped plates 62 expand outward. The two rubber pads contact and squeeze the inner wall of the product to be detected. When the inner wall of the product to be detected is completely supported by the rubber pads, the touch rod 61 is stuck. Subsequently, the telescopic oil cylinder 53 contracts, and the friction force 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.

[0031] In addition, it should be noted that when the movable slide rod 532 moves downward, the movable slide rod 532 will drive the guide head 56 and the camera body 57 to rotate downward through the sliding rod 562 and the connecting pipe 561. When the touch rod 61 is stuck, the camera body 57 just faces the upper edge of the product. When the movable slide rod 532 moves upward, the movable slide rod 532 will drive the guide head 56 and the camera body 57 to rotate upward through the sliding rod 562 and the connecting pipe 561. When the movable slide rod 532 moves upward to the highest point, the camera body 57 just faces the lower edge of the product. During the upward movement of the product, the camera body 57 can take a complete photo of the product from bottom to top, and can also take pictures of a certain area at different angles. That is to say, if there is a reflection when taking pictures of a certain area of the product, the captured images at other angles can be used as a backup for the image of this area to prevent the image of this area from being missing, so that the captured images of the product can achieve uniform clarity, thereby improving the detection accuracy.

[0032] After the detection is completed, the movable slide bar 532 moves downward. When the contact rod 61 is squeezed by the glass turntable 3 again, the contact rod 61 rebounds. At the same time, the two rubber pads disengage from the inner wall of the product. Subsequently, the contact rod 61 and the movable slide bar 532 move upward to complete one detection.

[0033] As a preferred embodiment, the guiding unit 58 includes a first connecting disk 71, a second connecting disk 72, a fixed cylinder 73, a first T-shaped slide bar 74, a first spherical head 75 and a first spring 76; the first connecting disk 71 is fixedly installed on the guiding head 56, the second connecting disk 72 is fixedly installed on the camera body 57, a first spherical groove is formed in the center of the second connecting disk 72, the fixed cylinder 73 is fixed in the center of the first connecting disk 71, a first snap ring 731 is fixed at one end of the fixed cylinder 73 away from the first connecting disk 71, the first T-shaped slide bar 74 is hermetically slidably arranged through the fixed cylinder 73, and the first T-shaped slide bar 74 is in sealed movable contact with the inner wall of the first snap ring 731. The first spherical head 75 is fixed at one end of the first T-shaped slide bar 74 away from the fixed cylinder 73, and the first spherical head 75 is arranged in the first spherical groove. The first spring 76 is connected between the first spherical head 75 and the inner wall of the first spherical groove.

[0034] Among them, the function of the first snap ring 731 is to prevent the first T-shaped slide bar 74 from sliding out of the fixed cylinder 73.

[0035] As a preferred embodiment, the guiding unit 58 further includes a stopper 81, a T-shaped block 82, a guiding cylinder 83, a second T-shaped slide bar 84, a second spherical head 85, a sealing ring 86, a second spring 87 and a third spring 88; a T-shaped ring groove 711 is formed on the eccentric side of the first connecting disk 71, the stopper 81 is fixed in the T-shaped ring groove 711, the T-shaped block 82 is hermetically slidably arranged in the T-shaped ring groove 711, the guiding cylinder 83 is fixed on the T-shaped block 82, an L-shaped flow channel 821 is formed in the T-shaped block 82, one end of the L-shaped flow channel 821 communicates with the guiding cylinder 83, and the other end communicates with the T-shaped ring groove 711 on the side facing the stopper 81. The second T-shaped slide bar 84 is hermetically slidably arranged through the guiding cylinder 83. A second snap ring 831 is fixed at one end of the guiding cylinder 83 away from the first connecting disk 71, and the second T-shaped slide bar 84 is in sealed movable contact with the second snap ring 831. A limiting ring groove 721 is formed on the eccentric side of the second connecting disk 72, the second spherical head 85 is fixed at one end of the second T-shaped slide bar 84 away from the guiding cylinder 83, and the second spherical head 85 is in movable contact with the inner wall of the limiting ring groove 721. The sealing ring 86 is fixed on the guiding cylinder 83, and the sealing ring 86 is in sealed movable contact with the side wall of the first connecting disk 71. Two second springs 87 are provided, one of which is connected between the first T-shaped slide bar 74 and the inner wall of the fixed cylinder 73, and the other is connected between the second T-shaped slide bar 84 and the inner wall of the guiding cylinder 83. The third spring 88 is connected between the stopper 81 and the T-shaped block 82.

[0036] Among them, similar to the function of snap ring 1 731, snap ring 2 831 can prevent T-shaped slide bar 2 84 from sliding out of the guide cylinder 83.

[0037] In addition, air guide holes 1 732 and air guide holes 2 832 are respectively formed in snap ring 1 731 and snap ring 2 831. The air guide holes 1 732 and air guide holes 2 832 can prevent pressure from being generated in the gaps between T-shaped slide bar 1 74 and fixed cylinder 73 and between T-shaped slide bar 2 84 and guide cylinder 83 respectively.

[0038] In the above, a sealed space is formed among the sealing ring 86, the stop block 81 and the T-shaped block 82. That is to say, when positive pressure is generated in this sealed space, the T-shaped block 82 will drive the guide cylinder 83 to slide along the direction of the T-shaped ring groove 711.

[0039] As a preferred embodiment, a communication hole is formed in the side wall of the oil cylinder 531, a micro solenoid valve 534 is arranged in the communication hole, the communication hole is communicated with the four guide cylinders 83 through a tree-shaped hose 91, and the guide cylinder 83 and the fixed cylinder 73 in each guiding unit 58 are communicated through a communication hose 92.

[0040] Among them, the micro solenoid valve 534 is controlled by the operation console 2.

[0041] It should be noted that the elastic forces of spring 2 87 and spring 3 88 gradually increase, and the sum of the elastic forces of the above springs is less than the frictional force between the movable slide bar 532 and the rubber layer.

[0042] For details, please refer to Figures 7 to 12, when the product moves upward along the movable slide bar 532 during the activity, the images captured by the four camera bodies 57 in real time will be transmitted to the operation console 2. If there are defects such as dents or material shortages on the product, at this time, the control center of the operation console 2 will control the micro solenoid valve 534 to open, and gradually inject hydraulic oil into the oil cylinder 531 from the external oil storage tank. At this time, the tree-shaped hose 91 is in communication with the oil cylinder 531, and the injected hydraulic oil will flow into the tree-shaped hose 91. There is a certain frictional force between the movable slide bar 532 and the rubber layer, so the movable slide bar 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, it can flow into the fixed cylinder 73 through the connecting hose 92. When the hydraulic oil is completely filled, since the resistance of the second spring 87 is less than that of the third spring 88, the first T-shaped slide bar 74 and the second T-shaped slide bar 84 will move synchronously first. The second connecting plate 72 will drive the camera body 57 closer to the product, so that the defective parts of the product can be focused and photographed, and the appearance of the defective parts can be photographed more clearly, further improving the detection accuracy of the product. When the first T-shaped slide bar 74 is limited by the first snap ring 731, the second T-shaped slide bar 84 continues to slide out of the guide cylinder 83, so the second connecting plate 72 and the camera body 57 will tilt. When tilted by a certain angle, the second T-shaped slide bar 84 is limited by the second snap ring 831. At this point, the camera body 57 is tilted to the maximum angle. After that, the pressure in the closed space of the T-shaped ring groove 711 increases. When this pressure is greater than the resistance of the third spring 88, the T-shaped block 82 will drive the guide cylinder 83 to slide along the T-shaped ring groove 711. Therefore, under the extrusion of the second spherical head 85, the second connecting plate 72 and the camera body 57 will perform a circular swing motion, so that the camera body 57 can completely photograph the internal appearance of the defective part, thus further improving the detection accuracy of the product.

[0043] The usage method and advantages of the present invention: The CCD full inspection machine for detecting the appearance of products works as follows: As Figures 1 to 12 shown: First, the product to be detected is introduced onto the glass turntable 3 through the feeding module 41. The fiber optic identification module 42 identifies the position of the product introduced onto the glass turntable 3, and then the product guiding module 43 adjusts the position of the product so that each product is unified to a certain determined position. The products at the determined positions will sequentially pass through the upper camera module 44 and the lower camera module 45 to photograph and detect the upper and lower ends of the product. Subsequently, the product will pass through the all-round detection component 46 to conduct a comprehensive inspection on each product one by one. After being inspected, the product will enter the export module 47 and be exported classified.

[0044] In summary, the CCD full inspection machine for detecting the appearance of products achieves the purpose of improving the detection accuracy and meets the usage requirements of people.
