DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] Embodiment 1:

[0029] Reference Figure 1-Figure 6 A glass plate surface defect automatic inspection machine includes an inspection box 1 and a conveyor belt 32, the conveyor belt 32 is located below the inspection point of the inspection box 1, and also includes: rollers 31 are sleeved at both ends of the conveyor belt 32; a CCD inspection module 12 is arranged in the inspection box 1, a spacer block 33 is arranged on the conveyor belt 32, and guard plates 34 are arranged on both sides of the conveyor belt 32; a push plate 62 is opened on one side of the guard plate 34, and a discharge port 64 is opened at a corresponding position on the other side of the guard plate 34; a discharge slide 4 is arranged above the conveyor belt 32; a storage box 2 is arranged above the discharge slide 4, and a push block 51 is arranged above the discharge slide 4.

[0030] In the present invention, a plurality of glass plates are stacked inside the storage box 2, and a certain distance is left between the storage box 2 and the end surface of the unloading slide 4, so that the push block 51 can push the bottom glass plate onto the slope of the unloading slide 4, and then the glass plate can fall onto the conveyor belt 32. The guard plates 34 on both sides of the conveyor belt 32 can effectively prevent the glass plate from sliding off the conveyor belt 32 during transportation. The spacer block 33 can apply a thrust to the glass plate during transportation, thereby preventing the glass plate from slipping on the conveyor belt 32. The conveyor belt 32 transports the glass plate to When it is under the detection box 1, it will stop for a certain period of time for the CCD detection module 12 to detect. After the detection is completed, the conveyor belt 32 continues to drive the glass plate to move forward. The push plate 62 is flush with the guard plate 34 when resetting to avoid the push plate 62 hindering the conveyor belt 32 from transporting the glass plate. When the CCD detection module 12 detects that the glass plate is unqualified, when the glass plate is transported to the push plate 62, the push plate 62 will push the unqualified glass plate out of the discharge port 64 for collection, and the qualified glass plate can be transported to the end by the conveyor belt 32 for collection.

[0031] Embodiment 2:

[0032] Reference Figure 1-Figure 6 , which is basically the same as Example 1, and furthermore: a first slide groove 22 is opened on the inner wall of the storage box 2, a back plate 21 is inserted into the first slide groove 22, first limit blocks 24 are fixed on both sides of the storage box 2, support frames 23 are fixed on both sides of the unloading slide 4, and adjusting bolts 25 are sleeved on the support frame 23, and the adjusting bolts 25 are inserted into the first limit blocks 24, a second driving part 5 is fixed to the upper end of the unloading slide 4, and second limit blocks 53 are provided on the inner walls on both sides of the unloading slide 4, and a first threaded rod 52 is fixed to the output end of the second driving part 5, and a first threaded rod 52 is sleeved on the first threaded rod 52 An L-shaped push block 51 is provided on one side of the guard plate 34 with a first support plate 35 and a second support plate 61, the first support plate 35 is fixed with a first driving part 3, the second support plate 61 is fixed with a third driving part 6, the output end of the first driving part 3 is connected to the roller 31, the output end of the third driving part 6 is connected to a second threaded rod 63, a plug-in slot 65 is fixed on the side wall of the guard plate 34, a collecting slot 7 is plugged into the plug-in slot 65, a plug-in block 71 is provided on the collecting slot 7, a plurality of pillars 36 are fixedly connected to the bottom of the guard plate 34, and a plurality of second supporting pillars 41 are fixed to the lower end surface of the unloading slide 4.

[0033] In the utility model, the back plate 21 can be inserted into the first slide groove 22, so that the user can pull out the back plate 21 to place the glass plate inside the storage box 2. The adjusting bolt 25 can rotate on the support frame 23. The support frame 23 supports and positions the adjusting nut. A threaded hole is provided on the first limit block 24. The user can adjust the distance between the storage box 2 and the upper surface of the unloading slide 4 by rotating the adjusting bolt 25, so as to cope with glass plates of different thicknesses, thereby increasing the versatility of the device.

[0034] A threaded hole is provided on the push block 51, and the push block 51 slides on the second limit block 53, so that when the second driving part 5 drives the first threaded rod 52 to rotate, the push block 51 can be horizontally moved along the direction of the second limit block 53, and then the protruding part below the push block 51 can push the glass plate at the bottom of the storage box 2 into the slope of the unloading slide 4. When the push block 51 is in the resetting process, the glass plate inside the storage box 2 is limited by the back plate 21 and will not be displaced. After the push block 51 completes the resetting, the glass plate automatically falls to the top of the unloading slide 4 and waits for the next push of the push block 51, thereby completing automatic unloading.

[0035] A threaded hole is provided on the push plate 62 and is sleeved on the second threaded rod 63, so that when the third driving part 6 drives the second threaded rod 63 to rotate, the push plate 62 can be horizontally displaced along the direction of the second threaded rod 63, and then the glass plate on the conveyor belt 32 can be pushed out from the discharge port 64 and sent into the collecting tank 7.

[0036] The other end of the second threaded rod 63 is sleeved on the guard plate 34 above the feed opening 64, so as to support the second threaded rod 63 and avoid the problem of the second threaded rod 63 sagging and deforming due to lack of support.

[0037] The first driving unit 3 drives the roller 31 to rotate, thereby controlling the operation of the conveyor belt 32 .

[0038] The collecting tank 7 is fixed to the side of the guard plate 34 by plugging the plug block 71 into the plug slot 65, so as to receive the unqualified glass plates. The plugging method also makes it convenient for the user to disassemble and replace the collecting tank 7.

[0039] The support column 36 supports the entire conveying mechanism, and the second support column 41 supports the unloading slide 4.

[0040] When in use, the user removes the back plate 21 in advance and puts the glass plate into the storage box 2, and resets the back plate 21, and then starts the device. The second driving part 5 will drive the pushing block 51 to push the glass plate under the storage box 2 to the slope of the unloading slide 4 according to the preset time interval, and the glass plate slides onto the conveyor belt 32 through the slope. Driven by the first driving part 3, the conveyor belt 32 transports the glass block to the bottom of the detection box 1 for inspection. After the inspection is completed, if the glass plate is detected to be unqualified, the CCD inspection module 12 will send information to the processing system, and the glass plate will be transported to the push plate 62 and pushed into the collecting tank 7 (because each glass plate will stay for a period of time when inspected, so when inspecting the next glass plate, the previous glass plate will stay at the position corresponding to the pushing block 51, so that the pushing block 51 completes the pushing process during the inspection). If the inspection is qualified, it will be transported to the end of the conveyor belt 32 for collection, thereby realizing the automation of glass plate inspection and screening.

[0041] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
