[0002] At present, the glass inner surface defect detection device is a device used to detect whether there are defects such as cracks, bubbles, scratches, etc. inside the glass. Defects on the inner surface of the glass may bring safety hazards. For example, scratches with sharp edges may scratch the user's lips or hands. If there are cracks inside the glass, when it is filled with liquid, especially hot liquid, it may cause the glass to suddenly break and scald the user. Through strict inner surface defect detection, these products with safety risks can be screened out to prevent them from entering the market, thereby ensuring the safety of consumers;

[0003] During the process of photographing and inspecting the inner wall of a glass, a light source is usually set at the bottom of the glass, and the light display difference at the defect position is used to assist in photographing and inspecting.

[0012] The present invention provides a device for detecting defects on the inner surface of a glass, which has the following beneficial effects:

[0013] 1. The device for detecting defects on the inner surface of a glass cup first contacts the mouth of the glass cup during detection by inclination of the flexural plate, and buffers the contact pressure when pressing down by deformation cooperation of the slip ring and the cushion tube. At the same time, during the buffering process, the position of the glass cup is adjusted by the inclination to make the glass cup perpendicular to the light source, thereby avoiding the deviation of light and the inner wall of the glass cup due to the inclination of the light source during detection, affecting the uniformity of light irradiation on the inner wall of the glass cup during shooting and detection, and causing the defects to be unable to be photographed and displayed.

[0014] 2. The device for detecting defects on the inner surface of a glass cup cooperates with a camera and a zigzag plate. During detection, the zigzag plate first contacts the glass cup and deforms the cushion tube under pressure. The zigzag plate and the slip ring move up synchronously. At this time, the distance between the camera and the bottom end of the zigzag plate gradually decreases until the camera passes through the bottom end of the zigzag plate. When the camera is shooting and detecting, it enters the inside of the glass cup, thereby improving the shooting effect and preventing the zigzag plate from blocking the camera's shooting image and affecting the detection.

[0015] 3. The device for detecting defects on the inner surface of a glass cup cooperates with the guide plate and the side baffle plate. When the glass cup is introduced, the side baffle plate restricts the two sides of the glass cup to prevent the glass cup from tipping over. At the same time, the side baffle plate cooperates with the guide plate to press the frontmost glass cup into the guiding mechanism along the center position of the guide plate to avoid direction deviation, which causes the glass to be unable to enter and affects the transportation of the glass cup.

[0016] Fourth, the device for detecting defects on the inner surface of a glass cup uses the side arc blocks to restrict the glass cup after it enters between the side arc blocks. When the glass cup is squeezed and positioned by the arc pressure plate and the guide mechanism, the position of the glass cup is restricted. When a cracked glass cup is squeezed, the device cooperates with the arc pressure plate to block the two sides of the glass cup to prevent the glass cup from breaking and splashing.

[0017] 5. The device for detecting defects on the inner surface of the glass cup cooperates with the shading ring and the arc pressure plate to shield the bottom of the glass cup during lighting detection, so as to prevent more light from passing through the bottom of the glass cup except the light provided by the lighting lamp, affecting the light irradiation of the lighting lamp and causing errors in the detection and shooting.

During the downward movement, the flexural plate 26 first contacts the mouth of the glass. After the contact, the flexural plate 26 applies pressure to the mouth of the glass to adjust the inclination of the glass to make the glass vertical.

The bottom end of the bending plate 26 is bent and tilted inward from top to bottom, and the bending plate 26 is evenly installed along the center position of the bottom ring 25. A camera 28 is fixedly installed on the inner wall of the fixed tube 21. During the sliding process, the bending plate 26 moves upward synchronously.

The bottom of the camera 28 is lower than the bottom of the fixed tube 21, and the bending part of the outer side of the bending plate 26 is fixedly installed with a limiting block 27.

[0035] A rotating column 304 is rotatably installed at one end of the connecting block 302 away from the supporting plate 311, a connecting frame 306 is fixedly installed on the outer side of the outer shield 301, a second cylinder 309 is fixedly installed on the outer side of the connecting frame 306, an arc pressure plate 307 is slidably installed on the inner wall of the connecting frame 306, and the arc pressure plate 307 is arc-shaped on the side close to the supporting plate 311. When the guiding mechanism 4 drives the glass cup to the top of the supporting plate 308, the arc pressure plate 307 is driven inward by the second cylinder 309, so that the arc pressure plate 307 cooperates with the guiding mechanism 4 to position the glass cup so that the glass cup is under the lighting lamp 310. 13 is directly above the glass, so that the light source passes through the glass, and cooperates with the detection mechanism 2 to shoot the inner wall of the glass to realize the detection of defects on the inner wall of the glass. At the same time, when the guiding mechanism 4 drives the glass, the side arc blocks 314 are used to limit the position of the arc pressure plate 307 on both sides. After the glass is transferred between the side arc blocks 314, the position of the glass is restricted, and the side of the arc pressure plate 307 away from the supporting plate 311 is fixedly connected to the output end of the second cylinder 309, and the inner wall of the outer baffle 301 is fixedly installed with the side arc blocks 314, and the side arc blocks 314 are symmetrically installed along the center position of the axis of the connecting frame 306.

[0036] The third embodiment is based on the first and second embodiments. Figures 8 to 9 As shown, the guide mechanism 4 includes a transmission shaft 402, the top end of the transmission shaft 402 is fixedly connected to the output end of the motor 5 through a coupling, the bottom end of the transmission shaft 402 is rotatably connected to the inner wall of the support plate 311 through a bearing, a fixing ring 403 is fixedly installed on the outer side of the transmission shaft 402, an arc groove plate 401 is fixedly installed on the outer side of the fixing ring 403, arc grooves are evenly opened on the outer side of the arc groove plate 401, and an arc plate 405 is fixedly installed on the top of the arc groove plate 401. The output end of the motor 5 is connected to the transmission shaft 402 through a coupling, and the bottom end of the transmission shaft 402 is rotatably connected to the inner wall of the support plate 311 through a bearing, and a fixing ring 403 is fixedly installed on the outer side of the fixing ring 403. The shaft 402 and the fixed ring 403 drive the arc groove plate 401 to rotate inside the supporting mechanism 3. When the glass cup is introduced, the arc groove of the arc groove plate 401 corresponds to the guide plate 303, so that under the squeezing effect of the glass cup during transportation, the frontmost glass cup enters the arc groove, and the arc plate 405 cooperates with the supporting mechanism 3 to make the glass cup enter the inner side of the arc plate 405. The arc plate 405 corresponds to the arc groove one by one. A shading ring 406 is fixedly installed on the bottom of the arc groove plate 401, and the shading ring 406 corresponds to the arc groove one by one.

[0037] The outer side of the arc plate 405 is symmetrically provided with a slide groove, and a slide plate 411 is slidably installed at the slide groove of the arc plate 405. A fixing bar 404 is fixedly installed on the top of the arc groove plate 401. The fixing bar 404 is located on the inner side of the arc plate 405. Both ends of the fixing bar 404 close to the arc plate 405 are fixedly installed with a slide rod 408. The outer side of the slide rod 408 is slidably connected with the inner wall of the slide plate 411. After contacting the rotating wheel 410, the squeezing force between the glass cups is transmitted to the slide plate 411 through the rotating wheel 410, so that the slide plate 411 compresses the spring 407 to deform, making the glass cup more Go deeper, and then the arc groove disk 401 rotates, driving the glass cup to move. At the same time, during the lighting detection process, the shading ring 406 cooperates with the arc pressure plate 307 to shade the bottom of the outer side of the glass cup, so that the light emitted by the lighting lamp 313 is blocked. A spring 407 is fixedly installed between the slide plate 411 and the fixed bar 404, and a connecting plate 409 is fixedly installed at the center position of the slide plate 411 away from the fixed bar 404. The two ends of the connecting plate 409 are inclined to the side away from the slide plate 411, and the two ends of the connecting plate 409 are rotatably installed with a rotating wheel 410.

[0038] When in use, the detection device is connected to the conveying device, so that the glass conveying device is driven and introduced into the interior of the support mechanism 3 from one side of the support mechanism 3. The support mechanism 3 cooperates with the guiding mechanism 4, so that the motor 5 drives the guiding mechanism 4 to rotate, and drives the glass to the other side. While moving, the detection mechanism 2 is driven to reciprocate up and down by the first cylinder 6. When moving downward, it cooperates with the support mechanism 3 to photograph the inner wall of the glass to detect defects. When the guiding mechanism 4 drives the glass to complete the inspection and arrives at the other side of the support mechanism 3, the guiding mechanism 4 cooperates with the conveying device to export the inspected glass.

[0039] When the glass is imported and exported by the conveying devices installed at both ends of the support mechanism 3, the conveying device responsible for importing drives the glass to the top of the guide plate 303, and squeezes the front glass through the subsequent glass, so that it moves to the inside of the outer baffle 301 under the restriction of the side baffle 305. The guide plate 303 is flush with the top of the support plate 311, and cooperates with the guide mechanism 4. When the glass is driven one by one and reaches the top of the support plate 308 by the guide mechanism 4, The second cylinder 309 drives the arc pressure plate 307 to move inward, so that the arc pressure plate 307 cooperates with the guiding mechanism 4 to position the glass cup so that the glass cup is directly above the lighting lamp 313, and the light source passes through the glass cup, and cooperates with the detection mechanism 2 to shoot the inner wall of the glass cup to realize the detection of defects on the inner wall of the glass cup. At the same time, when the guiding mechanism 4 drives the glass cup, the side arc blocks 314 are used to limit the two sides of the arc pressure plate 307. After the glass cup is transferred between the side arc blocks 314, the position of the glass cup is limited.

[0040] In the guiding mechanism 4, the output end of the motor 5 drives the arc groove disk 401 to rotate inside the supporting mechanism 3 through the transmission shaft 402 and the fixed ring 403. When the glass cup is introduced, the arc groove of the arc groove disk 401 corresponds to the guide plate 303, so that under the squeezing action of the glass cup during transportation, the frontmost glass cup enters the arc groove, and cooperates with the supporting mechanism 3 through the arc plate 405 to make the glass cup enter the inner side of the arc plate 405. At the same time, after contacting the rotating wheel 410, the squeezing force between the glass cups is transmitted to the slide plate 411 through the rotating wheel 410, so that the slide plate 411 compresses the spring 407 to deform, so that the glass cup goes deeper, and then the arc groove disk 401 rotates to drive the glass cup to move. At the same time, during the lighting detection process, the shading ring 406 cooperates with the arc pressure plate 307 to shield the bottom of the outer side of the glass cup, so that the light emitted by the lighting lamp 313 is blocked.

[0041] In the detection mechanism 2, when the glass reaches directly below the detection mechanism 2, the fixed cylinder 21 is driven by the first cylinder 6 to move downward. During the downward movement, the rim of the glass is first contacted by the flex plate 26. After the contact, the rim of the glass is pressed by the flex plate 26 to adjust the inclination of the glass to make the glass vertical. At the same time, while continuing to move downward and applying pressure, the pressure is transmitted to the bottom ring 25 and the slip ring 24 through the flex plate 26, so that the slip ring 24 compresses the cushion cylinder 23, causing the rubber of the cushion cylinder 23 to deform and the slip ring 24 to slide upward. At the same time, during the sliding process, the flex plate 26 moves upward synchronously. During the movement, the camera 28 gradually passes through the flex plate 26 and reaches the inside of the rim of the glass, and then photographs the inner wall of the glass to complete the detection of defects on the inner wall of the glass.
