[0001] This invention relates to the field of screen inspection technology, specifically to a fully automated screen defect inspection production line and its production process. Background Technology

[0002] Screen: A screen is a device or appliance used to display images and colors. It is divided into silver screens and fluorescent screens, also known as display screens, and is widely used in mobile phones, computers, monitors, televisions, and other devices with image or text display capabilities. Current technologies for detecting defects in screens have the following problems:

[0003] 1. Due to the large number of screens that need to be inspected on the production line, the existing technology makes it inconvenient to match each screen in batches with the inspection instrument, resulting in low efficiency in screen defect detection.

[0004] 2. At the same time, existing technologies are mostly inconvenient to remove dust from the screen surface during the screen testing process. When there is a lot of dust on the screen surface, it affects the accuracy of screen testing.

[0005] 3. After the screen inspection is completed, the inspected screens are divided into qualified products and defective products. However, the existing technology is not convenient for classifying and transporting the inspected screens, which makes it inconvenient to classify and process the screens in the future. In order to solve the above problems, the inventor proposes a fully automatic screen defect inspection production line and its production process. Summary of the Invention

[0012] A fully automated screen defect detection production process includes the following steps:

[0013] S1. Dust removal from the screen to be tested

[0014] When the screen passes through the sponge roller and soft brush, the rotation of the sponge roller and soft brush removes dust from the upper surface of the screen.

[0015] S2, Push of the screen to be tested

[0016] By driving the push plate to move horizontally to one side of the inspection table, the push plate pushes the screen, causing the screen to move along the channel between the two guide plates into the inspection slot. The screen entering the inspection slot is vertically aligned with the optical inspection instrument. The optical inspection instrument inspects the screen in the inspection slot to determine whether the screen is a qualified product.

[0017] S3. Classification of screens after detection

[0018] By driving the U-shaped frame to move horizontally towards one side of the second or third conveyor belt, the screen inside the U-shaped frame moves synchronously. When the screen is in complete contact with the second or third conveyor belt, the second or third conveyor belt transfers the screen.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0020] 1. When the screen passes through the sponge roller and soft brush, the sponge roller and soft brush are driven to rotate. The rotation of the sponge roller and soft brush removes dust from the upper surface of the screen, thus conveniently removing dust from the screen and avoiding the impact of excessive dust on the screen surface on subsequent optical inspection, thereby effectively improving the inspection accuracy of the screen.

[0021] 2. By driving the push plate to move horizontally to one side of the inspection table, the push plate pushes the screen, causing the screen to move along the channel between the two guide plates into the inspection slot. The screen entering the inspection slot is vertically aligned with the optical inspection instrument. The optical inspection instrument inspects the screen in the inspection slot to determine whether the screen is a qualified product. This conveniently realizes the automatic pushing of a single screen, so that each screen is vertically aligned with the optical inspection instrument, thereby effectively improving the convenience of screen inspection. At the same time, it effectively improves the automation level and efficiency of screen inspection.

[0022] 3. By driving the U-shaped material frame to move horizontally towards one side of the second or third conveyor belt, the screen inside the U-shaped material frame moves synchronously. When the screen is in complete contact with the second or third conveyor belt, the second or third conveyor belt transports the screen, thus facilitating the classification of the screens after inspection, and making it easier for subsequent staff to classify and process qualified and defective screens.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0036] Example: Figure 1-10As shown, the present invention provides a fully automated screen defect detection production line, including a first U-shaped frame 1, a second U-shaped frame 2, a third U-shaped frame 3, and a detection table 4. One side of the detection table 4 is fixedly connected to one side of the first U-shaped frame 1. One end of the second U-shaped frame 2 and the third U-shaped frame 3 is fixedly connected to one side of the first U-shaped frame 1. The other two sides of the detection table 4 are fixedly connected to the opposite sides of the second U-shaped frame 2 and the third U-shaped frame 3. A first conveyor belt 11 is installed internally in the first U-shaped frame 1. A U-shaped device is fixedly installed on the side of the first U-shaped frame 1 away from the detection table 4. The inner wall of the second U-shaped frame 2 is equipped with a second conveyor belt 21, and the inner wall of the third U-shaped frame 3 is equipped with a third conveyor belt 31. An L-shaped equipment frame 41 is fixedly installed on the upper surface of the testing table 4. An optical detector 42 is fixedly installed on the inner wall of the L-shaped equipment frame 41. A testing groove 43 is provided on the side of the testing table 4 near the L-shaped equipment frame 41. The testing groove 43 is at the same height as the second conveyor belt 21 and the third conveyor belt 31. A pushing mechanism 5 is provided inside the U-shaped equipment frame 13. A cleaning mechanism 7 is provided on the surface of the first U-shaped frame 1. A sorting mechanism 8 is provided on the surface of the testing table 4.

[0037] By adopting the above technical solution, a first conveyor belt 11 is set up to transport a batch of screens when the first conveyor belt 11 is in operation. A cleaning mechanism 7 is set up to clean the dust on the upper surface of the screens, so as to avoid the influence of excessive dust on subsequent optical inspection, thereby improving the inspection accuracy. A pushing mechanism 5 is set up to push the screens on the upper surface of the first conveyor belt 11 one by one and push the screens into the inspection slot 43. After the optical inspection instrument 42 completes the inspection of the screens in the inspection slot 43, a classification mechanism 8 is set up to classify and push the inspected screens. Qualified products are pushed to the upper surface of the second conveyor belt 21, and defective products are pushed to the upper surface of the third conveyor belt 31, thereby realizing the classification and division of the inspected screens.

[0038] Two guide plates 121 are fixedly installed on the upper surface of the testing table 4. A guide plate 12 is fixedly installed on the end of each guide plate 121 away from the testing table 4. The lower surface of the two guide plates 12 is in contact with the upper surface of the first conveyor belt 11. The two guide plates 12 and the two guide plates 121 are L-shaped. A notch 122 is opened at the end of one guide plate 12 that is close to one guide plate 121.

[0039] By adopting the above technical solution, and by setting two guide plates 12 and two guide plates 121, the L-shaped channel formed by the two guide plates 12 and two guide plates 121 facilitates the guidance of the screen during the conveying and pushing process, and avoids screen deviation.

[0040] The pushing mechanism 5 includes a pushing plate 51, which is in active contact with the inner wall of the notch 122. A connecting frame 55 is fixedly installed on the upper surface of the pushing plate 51. A U-shaped seat 56 is fixedly installed at the end of the connecting frame 55 away from the pushing plate 51. A rotating shaft 57 is rotatably installed on the inner wall of the U-shaped seat 56. A push rod 58 is fixedly installed on the outer wall of the rotating shaft 57.

[0041] By adopting the above technical solution, the push rod 58 is driven to reciprocate. The push rod 58 causes the push plate 51 to reciprocate horizontally through the rotating shaft 57, U-shaped seat 56 and connecting frame 55. When the push plate 51 moves horizontally in one direction, it pushes a screen on the upper surface of the first conveyor belt 11 into the detection groove 43.

[0042] The inner wall of the U-shaped equipment frame 13 has two guide grooves 52. The inner walls of the two guide grooves 52 are slidably connected with guide blocks 53. L-shaped connecting rods 54 are fixedly installed on opposite sides of the two guide blocks 53. The end of the L-shaped connecting rod 54 away from the guide block 53 is fixedly connected to one side of the push plate 51.

[0043] By adopting the above technical solution, by setting the guide groove 52, the guide block 53 and the L-shaped connecting rod 54, the guide block 53 guides the push plate 51 in the horizontal direction through the L-shaped connecting rod 54, so that the push plate 51 keeps moving in the horizontal direction.

[0044] A fixing plate 59 is fixedly installed on the upper surface of the U-shaped equipment frame 13. A first rotating rod 6 is rotatably installed on one side of the fixing plate 59. A rotating disk 61 is fixedly installed on the end of the first rotating rod 6 away from the fixing plate 59. A drive rod 62 is fixedly installed on the side of the rotating disk 61 away from the first rotating rod 6. The end of the drive rod 62 away from the rotating disk 61 is rotatably connected to one end of the push rod 58. A transmission gear 63 is fixedly installed on the end of the first rotating rod 6 away from the rotating disk 61. A first motor 64 is fixedly installed on one side of the U-shaped equipment frame 13. A second rotating rod 66 is fixedly installed on the drive output end of the first motor 64. A sector gear 67 is fixedly installed on the end of the second rotating rod 66 away from the first motor 64. The sector gear 67 and the transmission gear 63 are vertically aligned.

[0045] By adopting the above technical solution, by turning on the first motor 64, the drive shaft of the first motor 64 causes the second rotating rod 66 to rotate, and the second rotating rod 66 causes the sector gear 67 to mesh with the transmission gear 63. When the sector gear 67 meshes with the transmission gear 63, the sector gear 67 drives the transmission gear 63 to rotate, and the transmission gear 63 causes the first rotating rod 6 to rotate. The first rotating rod 6 causes the drive rod 62 to rotate around the axis of the rotating disk 61 through the rotating disk 61. The drive rod 62 causes the push rod 58 to reciprocate.

[0046] An L-shaped fixing bracket 65 is fixedly installed on one side of the U-shaped equipment frame 13, and the end of the first motor 64 is fixedly connected to the inner wall of the L-shaped fixing bracket 65.

[0047] By adopting the above technical solution, and by setting up an L-shaped fixing frame 65, the stability of the first motor 64 is improved.

[0048] The cleaning mechanism 7 includes two sponge rollers 71. Soft brushes 72 arranged in a ring array are fixedly installed on the outer walls of both sponge rollers 71. A third rotating rod 73 is fixedly installed at one end of each sponge roller 71. The two third rotating rods 73 pass through a guide plate 12 and are rotatably connected to the guide plate 12. A first synchronous pulley 74 is fixedly installed at one end of each third rotating rod 73. A first synchronous belt 75 is drivingly connected between the two first synchronous pulleys 74.

[0049] By adopting the above technical solution, by driving a third rotating rod 73 to rotate, the third rotating rod 73 causes another third rotating rod 73 to rotate synchronously and in the same direction through two first synchronous wheels 74 and a first synchronous belt 75. The third rotating rod 73 causes the sponge roller 71 and the soft brush 72 to rotate. When the screen on the upper surface of the first conveyor belt 11 passes the sponge roller 71 and the soft brush 72, the rotation of the sponge roller 71 and the soft brush 72 cleans the dust on the upper surface of the screen.

[0050] A first transmission rod 76 is fixedly installed at one end of a third rotating rod 73. A second transmission rod 77 is rotatably installed on one side of the U-shaped equipment frame 13. A bevel gear 78 is fixedly installed at one end of the second transmission rod 77 and one end of the first transmission rod 76. The two bevel gears 78 mesh with each other. A second synchronous pulley 79 is fixedly installed at the end of the second rotating rod 66 near the first motor 64 and the end of the second transmission rod 77 away from the U-shaped equipment frame 13. A second synchronous belt 791 is connected between the two second synchronous pulleys 79.

[0051] By adopting the above technical solution, when the second rotating rod 66 rotates, the second rotating rod 66 causes the second transmission rod 77 to rotate through two second synchronous pulleys 79 and a second synchronous belt 791. The second transmission rod 77 causes the first transmission rod 76 to rotate through two bevel gears 78. The first transmission rod 76 causes a third rotating rod 73 to rotate.

[0052] The sorting mechanism 8 includes a U-shaped material frame 81, an optical detector 42, and the U-shaped material frame 81 vertically corresponding to each other. The inner wall of the U-shaped material frame 81 and the detection groove 43 are in movable contact. A discharge groove 811 is provided on one side of the U-shaped material frame 81. A frame plate 82 is fixedly installed on the upper surface of the detection table 4. A sliding groove 83 is provided on one side of the frame plate 82. A slider 84 is slidably connected to the inner wall of the sliding groove 83. Two fixing rods 85 are fixedly installed on one side of the slider 84. The ends of the two fixing rods 85 away from the slider 84 are fixedly connected to one side of the U-shaped material frame 81. A toothed plate 86 is fixedly installed on one side away from the fixed rod 85. A second motor 87 is fixedly installed on the side of the detection table 4 away from the detection groove 43. A fixed block 88 is fixedly installed on the outer wall of the second motor 87. The side of the detection table 4 away from the detection groove 43 is fixedly connected to the fixed block 88. A fourth rotating rod 89 is fixedly installed at the drive output end of the second motor 87. The fourth rotating rod 89 passes through the detection table 4 and is rotatably connected to the detection table 4. A drive gear 9 is fixedly installed at the end of the fourth rotating rod 89 away from the second motor 87. The drive gear 9 is meshed with the toothed plate 86.

[0053] By adopting the above technical solution, after the screen in the U-shaped frame 81 is inspected, the second motor 87 is turned on. The drive shaft of the second motor 87 rotates in both directions, and the drive gear 9 rotates in both directions through the fourth rotating rod 89. The drive gear 9 drives the toothed plate 86 to move horizontally towards one side of the second conveyor belt 21 or the third conveyor belt 31. The toothed plate 86 causes the slider 84 to slide horizontally along the inner wall of the slide groove 83. The slider 84 moves horizontally synchronously with the U-shaped frame 81 and the screen in the U-shaped frame 81 through the fixing rod 85. When the U-shaped frame 81 moves horizontally towards one side of the second conveyor belt 21, the qualified screen is moved to the upper surface of the second conveyor belt 21. When the U-shaped frame 81 moves horizontally towards one side of the third conveyor belt 31, the qualified screen is moved to the upper surface of the third conveyor belt 31. With the transmission of the second conveyor belt 21 and the third conveyor belt 31, the screen in the U-shaped frame 81 is separated from the U-shaped frame 81 through the discharge groove 811.

[0054] A fully automated screen defect detection production process includes the following steps:

[0055] S1. Dust removal from the screen to be tested

[0056] When the screen passes through the sponge roller 71 and the soft brush 72, the sponge roller 71 and the soft brush 72 are driven to rotate, and the rotation of the sponge roller 71 and the soft brush 72 removes dust from the upper surface of the screen.

[0057] S2, Push of the screen to be tested

[0058] By driving the push plate 51 to move horizontally towards one side of the inspection table 4, the push plate 51 pushes the screen, causing the screen to move along the channel between the two guide plates 121 into the inspection slot 43. The screen entering the inspection slot 43 is vertically aligned with the optical inspection instrument 42. The optical inspection instrument 42 inspects the screen in the inspection slot 43 to determine whether the screen is a qualified product.

[0059] S3. Classification of screens after detection

[0060] By driving the U-shaped material frame 81 to move horizontally towards one side of the second conveyor belt 21 or the third conveyor belt 31, the screen inside the U-shaped material frame 81 moves synchronously. When the screen is in complete contact with the second conveyor belt 21 or the third conveyor belt 31, the second conveyor belt 21 or the third conveyor belt 31 transmits the screen.

[0061] Working principle: When a batch of screens needs to be inspected, the operator first starts the first conveyor belt 11 to transport the screens. When the foremost screen approaches the cleaning mechanism 7, the operator starts the first motor 64. The drive shaft of the first motor 64 causes the second rotating rod 66 to rotate. The second rotating rod 66, through two second synchronous pulleys 79 and a second synchronous belt 791, causes the second transmission rod 77 to rotate. The second transmission rod 77, through two bevel gears 78, causes the first transmission rod 76 to rotate. The first transmission rod 76 then causes a corresponding third rotating rod... 73 rotates, and one third rotating rod 73 causes another third rotating rod 73 to rotate synchronously in the same direction through two first synchronous pulleys 74 and a first synchronous belt 75. At this time, the two third rotating rods 73 cause two sponge rollers 71 and multiple soft brushes 72 to rotate. When the foremost screen passes the two sponge rollers 71 and multiple soft brushes 72, the rotation of the two sponge rollers 71 and multiple soft brushes 72 cleans the dust on the upper surface of the screen, thus conveniently realizing the dust removal of the screen and avoiding the impact of a lot of dust on the screen surface on subsequent optical inspection, thereby effectively improving the inspection accuracy of the screen.

[0062] When the foremost screen is conveyed to the front side of the push plate 51, the sector gear 67 meshes with the transmission gear 63. The sector gear 67 drives the transmission gear 63 to rotate, and the transmission gear 63 causes the first rotating rod 6 to rotate. The first rotating rod 6 causes the drive rod 62 to rotate around the axis of the rotating disk 61 via the rotating disk 61. The drive rod 62 causes the push plate 51 to move horizontally towards one side of the detection table 4 via the push rod 58, the rotating shaft 57, the U-shaped seat 56, and the connecting frame 55. At this time, the push plate 51 pushes the screen. After the screen is pushed into the detection slot 43, the push plate 51 moves in the opposite direction and resets. At this time, the sector gear 67 disengages from the transmission gear 63, thus conveniently realizing the automatic pushing of a single screen, so that each screen is vertically aligned with the optical detector 42, thereby effectively improving the convenience of screen detection. At the same time, it effectively improves the automation level and efficiency of screen detection.

[0063] After the optical inspection instrument 42 finishes inspecting the screen, if the screen is determined to be a qualified product, the operator starts the second motor 87, causing the drive shaft of the second motor 87 to rotate clockwise. The drive shaft of the second motor 87, through the fourth rotating rod 89, causes the drive gear 9 to rotate clockwise. The drive gear 9 causes the toothed plate 86 to move horizontally towards one side of the second conveyor belt 21. The toothed plate 86, through the slider 84 and two fixed rods 85, causes the U-shaped frame 81 and the screen inside the U-shaped frame 81 to move synchronously towards one side of the second conveyor belt 21. When the U-shaped frame 81 is fully in contact with the second conveyor belt 21, the second conveyor belt 21 transports the qualified screens. If the screen is determined to be a defective product, the drive shaft of the second motor 87 is rotated counterclockwise, and the U-shaped frame 81 and the defective screen move horizontally towards one side of the third conveyor belt 31. The third conveyor belt 31 transports the defective screens, thus facilitating the classification of the inspected screens and making it easier for subsequent operators to classify and process qualified and defective screens.
