[0015] Working process or working principle: When working, the connecting column and the hollow support cylinder support the dual-axis motor, thereby improving the stability of the dual-axis motor. When the carrier glass needs to be inspected for defects, it can be placed on the placement plate first. It should be noted that when placing the carrier glass, one side of the glass needs to be flush with one side of the L-shaped support plate. After the glass is placed, it can be pressed down to fix the glass on the placement plate with the help of the suction cup.

[0016] After the glass is fixed, the dual-axis motor can be driven to rotate the output end with the pulley, thereby transmitting the torque output by the dual-axis motor to the first reciprocating screw rod through the belt and the pulley, so that the first reciprocating screw rod rotates in the middle of the first hollow groove. When the first reciprocating screw rod rotates, it will drive the threaded slider to move synchronously, and the movement of the threaded slider will drive the L-shaped support plate to move, and then drive the guide slider to move. The movement of the guide slider will be restricted by the support guide column, so that it slides toward the placement plate in the middle of the support guide column, thereby changing the movement trajectory of the threaded slider and the L-shaped support plate, forcing them to move along the movement trajectory of the guide slider.

[0017] When the L-shaped support plate slides toward the suction cup, its upright part will gradually approach the carrier glass on the placement plate, thereby driving the semicircular rubber pad to contact the glass end surface. At this time, the semicircular rubber pad will drive the conical top column and the round block to slide toward the hollow column under the pressure of the glass end surface and the L-shaped support plate moving, thereby squeezing the spring, causing the spring to be compressed under the influence of pressure, and the sliding of the round block will drive the positioning column to slide to the side away from the L-shaped support plate, thereby changing the end position of the positioning column, and when the glass end surface in contact with the semicircular rubber pad has a defect, due to the different pressure, the end position of the positioning column will be different from the position of the positioning column in contact with the glass end surface without defects, thereby providing a more direct observation for the staff, making it easier for the staff to mark the defective part of the carrier glass end surface.

[0018] During operation, after the position of the L-shaped support plate is moved, the output end of the dual-axis motor with the worm can be driven to rotate, so that the worm rotates synchronously in the middle of the first support block. Because the worm wheel and the worm are in a state of mutual meshing, the rotation of the worm will drive the worm wheel to rotate accordingly, and the rotation of the worm wheel will drive the two ends of the second reciprocating screw to rotate respectively in the middle of the two groups of second support blocks. The rotation of the second reciprocating screw will drive the threaded sleeve and the rectangular slide to move. At this time, because the two sides of the rectangular slide are in contact with the two sides of the hollow slide groove, the movement of the rectangular slide will be restricted by the hollow slide groove, and then drive the threaded sleeve and the placement plate to move in a straight line. The movement of the placement plate will drive the carrier glass on its top to move. At this time, the end face of the carrier glass in contact with the semicircular rubber pad will move at multiple groups of semicircular rubber pads, so that every side of the carrier glass in contact with the semicircular rubber pad can be detected for defects.

[0019] Compared with the prior art, the present invention has the following beneficial effects: 1. In this carrier glass defect locating device, through the setting of the defect locating component, the L-shaped support plate can be moved so that the semicircular rubber pad contacts the end face of the carrier glass, so that by observing the end position of the positioning column, there is a more direct observation of whether there is a defect on the end face of the carrier glass. At the same time, it is also convenient to locate and mark the defects, thereby reducing the flow of defective glass into the market, causing endangerment to user personal safety and affecting the company's market competitiveness and brand reputation.

[0020] 2. In this carrier glass defect positioning device, the sliding component is set up so that the end faces of the carrier glass can all contact with the semicircular rubber pads, thereby performing comprehensive defect detection, thereby reducing the gaps between multiple groups of semicircular rubber pads, which easily cause incomplete detection of the end faces of the carrier glass in contact with the semicircular rubber pads, and further cause the staff to miss the mark on the defects of the carrier glass.

[0024] Although the device can determine the grinding condition of the end face of the carrier glass, it lacks a means to locate defects on the end face of the carrier glass, which makes it easy for defects such as cracks and broken edges of the carrier glass to be overlooked, causing defective glass to flow into the market and cause a series of problems.

One end of the first reciprocating screw 3 is rotatably connected to one end of the first hollow groove 2, and the other end of the first reciprocating screw 3 is rotatably connected to the side of the defect positioning platform 1 close to the first hollow groove 2. The two ends of the support guide column 31 are respectively fixedly connected to the two ends of the second hollow groove 21. The two pulleys 32 are respectively fixedly connected to one end of the first reciprocating screw 3 close to the defect positioning platform 1 and one end of the hollow support cylinder 23 close to the first reciprocating screw 3. The two ends of the belt 33 are respectively sleeved on the middle part of the two sets of pulleys 32.

[0028] The defect positioning assembly also includes a threaded slider 4, a guide slider 41, an L-shaped support plate 42 and multiple groups of hollow columns 43. The threaded slider 4 is threadedly connected to the middle part of the first reciprocating screw 3, the guide slider 41 is slidably connected to the middle part of the support guide column 31, the two ends of the bottom of the L-shaped support plate 42 are fixedly connected to the threaded slider 4 and the top of the guide slider 41, and the hollow columns 43 are all fixedly connected to the upright side of the L-shaped support plate 42.

[0029] The defect locating assembly also includes multiple groups of springs 5, multiple groups of circular blocks 51 and multiple groups of positioning columns 52. One end of the spring 5 is fixedly connected to the upright side of the L-shaped support plate 42, and the multiple groups of springs 5 ​​are respectively located in the middle of the multiple groups of hollow columns 43. The circular block 51 is fixedly connected to the end of the spring 5 away from the L-shaped support plate 42, and the multiple groups of circular blocks 51 are respectively slidably connected to the middle of the multiple groups of hollow columns 43.

[0030] The defect locating assembly also includes multiple groups of conical top columns 6 and multiple groups of semicircular rubber pads 61. One end of the conical top column 6 is fixedly connected to the side of the multiple groups of circular blocks 51 away from the spring 5, and the semicircular rubber pads 61 are fixedly connected to the end of the conical top column 6 away from the circular block 51.

[0031] During operation, the connecting column 22 and the hollow support tube 23 support the dual-axis motor 24, thereby improving the stability of the dual-axis motor 24. When it is necessary to perform defect detection on the carrier glass, it can be placed on the placement plate 13 first. It should be noted that when placing the carrier glass, one side of the glass needs to be flush with one side of the L-shaped support plate 42. After the glass is placed, it can be pressed down to fix the glass on the placement plate 13 with the help of the suction cup 14.

[0032] After the glass is fixed, the dual-axis motor 24 can be driven to rotate its output end with the pulley 32, thereby transmitting the torque output by the dual-axis motor 24 to the first reciprocating screw 3 through the belt 33 and the pulley 32, so that the first reciprocating screw 3 rotates in the middle of the first hollow groove 2. When the first reciprocating screw 3 rotates, it will drive the threaded slider 4 to move synchronously, and the movement of the threaded slider 4 will drive the L-shaped support plate 42 to move, and then drive the guide slider 41 to move. The movement of the guide slider 41 will be restricted by the support guide column 31, so that it slides toward the placement plate 13 in the middle of the support guide column 31, thereby changing the movement trajectory of the threaded slider 4 and the L-shaped support plate 42, forcing them to move along the movement trajectory of the guide slider 41.

[0033] When the L-shaped support plate 42 slides toward the suction cup 14, its upright part will gradually approach the carrier glass at the placement plate 13, thereby driving the semicircular rubber pad 61 to contact the glass end surface. At this time, the semicircular rubber pad 61 will drive the conical top column 6 and the circular block 51 to slide toward the hollow column 43 under the pressure of the glass end surface and the L-shaped support plate 42 when moving, thereby squeezing the spring 5, causing the spring 5 to be compressed under the influence of the pressure, and the sliding of the circular block 51 will drive the positioning column 52 to slide to the side away from the L-shaped support plate 42, thereby changing the end position of the positioning column 52, and when the glass end surface in contact with the semicircular rubber pad 61 has a defect, due to the different pressure, the end position of the positioning column 52 will be different from the position of the positioning column 52 in contact with the glass end surface without defects, thereby providing a more direct observation for the staff, making it easier for the staff to mark the defective part of the carrier glass end surface.

[0034] In this step, by setting up the defect positioning component, the L-shaped support plate 42 can be moved so that the semicircular rubber pad 61 contacts the end surface of the carrier glass, so that by observing the end position of the positioning column 52, there is a more direct observation of whether there are defects on the end surface of the carrier glass. At the same time, it is also convenient to locate and mark the defects, thereby reducing the flow of defective glass into the market, causing dangers to users' personal safety and affecting the company's market competitiveness and brand reputation.

[0035] For further information, see Figure 1 、 Figure 2 、 Figure 6 、 Figure 7 and Figure 8 As shown, the sliding assembly includes a hollow slide groove 7, a first support block 71 and two groups of second support blocks 72. The hollow slide groove 7 is opened in the middle of the top surface of the defect positioning platform 1. The first support block 71 is fixedly connected to one side of the bottom of the defect positioning platform 1. The two first support blocks 71 are respectively fixedly connected to both sides of the bottom of the defect positioning platform 1.

[0036] The sliding assembly also includes a worm 8, a second reciprocating screw 81 and a worm wheel 82. One end of the worm 8 is rotatably connected to the middle of the first support block 71, and the other end of the worm 8 is fixedly connected to the output end of the hollow support cylinder 23 away from the pulley 32. The two ends of the second reciprocating screw 81 are respectively rotatably connected to the middle of the two groups of second support blocks 72. The worm wheel 82 is fixedly connected to one end of the second reciprocating screw 81 close to the worm 8, and the worm wheel 82 is engaged with the worm 8.

[0037] The sliding assembly further includes a threaded sleeve 9 and a rectangular sliding column 91 . The threaded sleeve 9 is threadedly connected to the middle portion of the second reciprocating screw 81 , and the bottom portion of the rectangular sliding column 91 is fixedly connected to the top portion of the threaded sleeve 9 .

[0038] One end of the rectangular slide 91 away from the threaded sleeve 9 is fixedly connected to the bottom of the placement plate 13, and the rectangular slide 91 is slidably connected to the middle of the hollow slide groove 7, and both sides of the rectangular slide 91 are in contact with both sides of the hollow slide groove 7.

[0039] During operation, after the position of the L-shaped support plate 42 is moved, the output end of the dual-axis motor 24 with the worm 8 can be driven to rotate, so that the worm 8 rotates synchronously in the middle of the first support block 71. Since the worm wheel 82 and the worm 8 are in a state of mutual meshing, the rotation of the worm 8 will drive the worm wheel 82 to rotate accordingly, and the rotation of the worm wheel 82 will drive the two ends of the second reciprocating screw 81 to rotate in the middle of the two sets of second support blocks 72 respectively. The rotation of the second reciprocating screw 81 will drive the threaded sleeve 9 and the rectangular The slide column 91 moves. At this time, because the two sides of the rectangular slide column 91 fit with the two sides of the hollow slide groove 7, the movement of the rectangular slide column 91 will be restricted by the hollow slide groove 7, thereby driving the threaded sleeve 9 and the placement plate 13 to move in a straight line. The movement of the placement plate 13 will drive the carrier glass on the top to move. At this time, the end surface of the carrier glass in contact with the semicircular rubber pad 61 will move at multiple groups of semicircular rubber pads 61, so that every side of the carrier glass in contact with the semicircular rubber pad 61 is inspected for defects.

[0040] In this step, the sliding assembly is set up so that the end faces of the carrier glass can all contact with the semicircular rubber pads 61, thereby performing comprehensive defect detection, thereby reducing the gaps between multiple groups of semicircular rubber pads 61, which can easily cause incomplete detection of the end faces of the carrier glass in contact with the semicircular rubber pads 61, and further lead to the staff missing marks on the defects of the carrier glass.

[0041] To sum up, the problem that although the device can determine the grinding condition of the end face of the carrier glass, it lacks the means to locate the defects on the end face of the carrier glass, which makes it easy for defects such as cracks and broken edges of the carrier glass to be ignored, thereby causing defective glass to flow into the market and triggering a series of problems.
