Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a device for detecting defects in glass cover plates. Background Technology

[0002] As a key component covering high-requirement applications such as electronic displays and photovoltaic cells, glass covers must have a flawless surface to ensure the visual quality and functional performance of the products. Therefore, a defect detection device is needed to detect defects on the surface of the glass cover in real time on the production line, promptly identify and eliminate problematic products, thereby ensuring product quality consistency. Furthermore, an automated defect detection device can reduce labor input, i.e., reduce production costs. Existing detection devices can only simply scan the glass cover from above to detect whether there are defects, and cannot automatically flip the glass cover over to scan and detect the other surface of the glass cover. Moreover, they cannot automatically clean the dust adhering to the surface of the glass cover before detection, and the dust adhering to the glass cover can easily affect the accuracy of the detection results. Therefore, this invention provides a glass cover defect detection device. Summary of the Invention

[0003] This invention addresses the shortcomings of existing technologies by providing a glass cover plate defect detection device. It overcomes the problems of not being able to automatically flip the glass cover plate, i.e., not being able to scan and detect the other surface of the glass cover plate, and not being able to automatically clean the dust adhering to the surface of the glass cover plate before detection, which can easily affect the accuracy of the detection results.

[0004] To achieve the above objectives, the present invention provides the following technical solution: a glass cover plate defect detection device, comprising a base, a conveying assembly on the base, a pick-and-place assembly on the base, the pick-and-place assembly including a fan-shaped ring plate, a pick-and-place rotating frame rotatably mounted on the fan-shaped ring plate, a long-arm sliding plate slidably mounted on the pick-and-place rotating frame, an adjustment unit between the long-arm sliding plate and the fan-shaped ring plate, the adjustment unit being used to adjust the position of the long-arm sliding plate relative to the pick-and-place rotating frame, a suction cup and a vacuum pump fixedly mounted at the end of the long-arm sliding plate, the vacuum pump and the suction cup being connected, a support assembly and an auxiliary assembly on the base, the support assembly including a support frame, semi-circular support plates symmetrically slidably mounted on the support frame, the two semi-circular support plates forming a complete circular plate when joined, a groove for accommodating the movement of the long-arm sliding plate being provided on the circular plate formed when the two semi-circular support plates are joined, an unfolding unit being provided between the two semi-circular support plates, the unfolding unit being used to adjust the position between the two semi-circular support plates, and the auxiliary assembly being used for cleaning and detecting the surface of the glass cover plate.

[0005] Furthermore, a sector-shaped support seat is fixedly installed on the base, and a sector-shaped ring plate is rotatably installed on the sector-shaped support seat. The opening position of the sector-shaped ring plate is used to make way for the movement of the long-arm slide plate. A shift gear is also symmetrically rotatably installed on the sector-shaped support seat, and a sector-shaped shift rack is fixedly installed on the sector-shaped ring plate. When the shift gear and the sector-shaped shift rack are engaged, they form a gear pair, and a transmission group is provided between the two shift gears.

[0006] Furthermore, the positioning unit includes a drive shaft rotatably mounted inside the sector ring plate. The drive shaft and the pick-and-place rotating frame are rotatably connected. The center line of the rotatable connection between the drive shaft and the pick-and-place rotating frame is on the same straight line as the center line of the rotatable connection between the pick-and-place rotating frame and the sector ring plate. A torsion spring is provided between the drive shaft and the pick-and-place rotating frame.

[0007] Furthermore, an adjusting gear is fixedly installed at the end of the drive shaft closest to the long arm slide plate, and an adjusting rack is fixedly installed on the side of the long arm slide plate. The adjusting rack and the adjusting gear engage to form a gear and rack pair. An L-shaped limiting plate is fixedly installed symmetrically on the fan-shaped ring plate. The L-shaped limiting plate is used to limit the rotation position of the pick-up and put-down rotating frame.

[0008] Furthermore, the support frame is fixedly installed on the base, and springs are provided between the semi-circular support plate and the support frame. When the two semi-circular support plates are joined and the long arm slide is in a horizontal state, the axis of the circular plate formed by the joining of the two semi-circular support plates and the axis of the suction cup on the long arm slide are on the same straight line.

[0009] Furthermore, the unfolding unit includes a circular rotating frame and a linkage gear rotatably mounted on the base. Two sector-shaped linkage racks are fixedly arranged in the inner circumferential array of the circular rotating frame. When the sector-shaped linkage racks and the linkage gears are engaged, they form a gear rack pair. A strip-shaped push plate is rotatably mounted on the support frame. The semi-circular support plate is fixedly equipped with unfolding slide plates at the ends closest to the circular rotating frame. The strip-shaped push plate is used to push the two unfolding slide plates to move. An unfolding gear is fixedly mounted on the strip-shaped push plate. The unfolding gear and the linkage gear are engaged to form a gear pair. The axis of the unfolding gear and the center line of the circular rotating frame are on the same straight line.

[0010] Furthermore, a transmission gear is rotatably mounted on the base, and the transmission gear is fixedly connected to the shift gear closest to the transmission gear. Two sector-shaped transmission racks are fixedly arranged in a circumferential array on the circular rotating frame. When the sector-shaped transmission racks engage with the transmission gear, they form a gear rack pair.

[0011] Furthermore, the auxiliary components include an air knife that is slidably mounted on the base, an auxiliary lead screw that is fixedly mounted on the side of the air knife, and an auxiliary pulley that is rotatably mounted on the base. The auxiliary pulley and the auxiliary lead screw form a helical pair, and the air knife is used to clean the surface of the glass cover plate.

[0012] Furthermore, the auxiliary components also include two scanners, which are symmetrically fixed on the base. The two scanners are symmetrically arranged with respect to the axis of the circular plate formed when the two semi-circular support plates are joined. The scanners are used to scan and detect defects on the surface of the glass cover.

[0013] The advantages of this invention compared with the prior art are as follows: (1) By setting an adjustment unit, this invention can quickly adjust the position of the long-arm slide plate, thereby facilitating the picking up and placing of the glass cover and adjusting its position. (2) By setting a semi-circular support plate, this invention can support the lower surface of the glass cover plate when the air knife cleans the dust on the upper surface of the glass cover plate, thereby preventing the glass cover plate from bending and being damaged during the cleaning process. (3) By setting an unfolding unit, this invention can quickly move the positions of the two semi-circular support plates, thereby making way when the long-arm slide plate flips the glass cover plate. (4) By setting an auxiliary component, this invention can clean the dust attached to the surface of the glass cover plate before scanning and detection, thereby avoiding the dust attached to the glass cover plate from affecting the accuracy of the detection results.

Detailed Implementation

[0024] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

[0025] Example: Reference Figures 1-9 A glass cover plate defect detection device includes a base 101, on which a conveyor group 102 is disposed. The conveyor group 102 includes a conveyor belt and two conveyor rollers. The two conveyor rollers in the conveyor group 102 are rotatably mounted on the base 101. The conveyor belt in the conveyor group 102 is disposed on the two conveyor rollers. A conveyor motor 103 is fixedly mounted on the base 101. The output shaft of the conveyor motor 103 is fixedly connected to the corresponding conveyor group 102. When the conveyor motor 103 is started, it drives the corresponding conveyor roller to rotate, thereby causing the conveyor belt in the conveyor group 102 to rotate. That is, under the action of the conveyor group 102, the glass cover plate to be inspected is conveyed.

[0026] A pick-and-place assembly is provided on the base 101, including a sector-shaped ring plate 106. A sector-shaped support base 134 is fixedly mounted on the base 101. The sector-shaped ring plate 106 is rotatably mounted on the sector-shaped support base 134. The opening of the sector-shaped ring plate 106 is used to allow space for the movement of the long-arm sliding plate 109. A shift gear 114 is symmetrically rotatably mounted on the sector-shaped support base 134. A sector-shaped shift rack 113 is fixedly mounted on the sector-shaped ring plate 106. When the shift gear 114 and the sector-shaped shift rack 113 are engaged, they form a gear pair. A transmission assembly is provided between the two shift gears 114. 115, the transmission group 115 includes a belt and two pulleys. The two pulleys in the transmission group 115 are respectively fixedly mounted on the corresponding shift gears 114. The belt in the transmission group 115 is arranged on the two pulleys and drives one of the shift gears 114 to rotate. Under the action of the transmission group 115, the two shift gears 114 rotate synchronously. As a result, under the action of the two shift gears 114, the sector-shaped shift rack 113 can continuously rotate relative to the axis of the sector-shaped support 134, and the sector-shaped ring plate 106 rotates synchronously.

[0027] A pick-and-place frame 111 is rotatably mounted on a sector-shaped ring plate 106. A long-arm sliding plate 109 is slidably mounted on the pick-and-place frame 111. An adjustment unit is provided between the long-arm sliding plate 109 and the sector-shaped ring plate 106. The adjustment unit is used to adjust the position of the long-arm sliding plate 109 relative to the pick-and-place frame 111. A suction cup 110 and a vacuum pump 123 are fixedly mounted at the end of the long-arm sliding plate 109 furthest from the sector-shaped ring plate 106. The vacuum pump 123 and the suction cup 110 are connected. The adjustment unit includes a drive shaft 117 rotatably mounted inside the sector-shaped ring plate 106. An adjustment motor 116 is also fixedly installed inside the fan-shaped ring plate 106. The output shaft of the adjustment motor 116 is fixedly connected to the transmission shaft 117. The transmission shaft 117 is rotatably connected to the pick-and-place rotating frame 111. The center line of the rotatable connection between the transmission shaft 117 and the pick-and-place rotating frame 111 is on the same straight line as the center line of the rotatable connection between the pick-and-place rotating frame 111 and the fan-shaped ring plate 106. A torsion spring is provided between the transmission shaft 117 and the pick-and-place rotating frame 111. One end of the torsion spring is fixedly connected to the transmission shaft 117, and the other end of the torsion spring is fixedly connected to the pick-and-place rotating frame 111.

[0028] An adjusting gear 118 is fixedly installed at the end of the drive shaft 117 closest to the long arm slide plate 109. An adjusting rack 112 is fixedly installed on the side of the long arm slide plate 109. The adjusting rack 112 and the adjusting gear 118 are engaged to form a gear rack pair. An L-shaped limiting plate 124 is fixedly fixedly arranged on the fan-shaped ring plate 106 in an axially symmetrical manner. The L-shaped limiting plate 124 is used to limit the rotation position of the pick-up and put-down rotating frame 111.

[0029] In the initial position, the torsion spring between the drive shaft 117 and the pick-and-place rotating frame 111 is not compressed, the long arm slide plate 109 is located at the position closest to the axis of the fan-shaped ring plate 106, the pick-and-place rotating frame 111 contacts the side of the L-shaped limiting plate 124, at this time the pick-and-place rotating frame 111 is in a vertically downward state, the end of the auxiliary screw 119 farthest from the fan-shaped ring plate 106 is located at the position farthest from the conveying group 102, and the adjusting rack 112 is located at the position farthest from the lower surface of the base 101.

[0030] refer to Figure 3 When the adjustment motor 116 is started, the drive shaft 117 is driven to rotate clockwise. At this time, the pick-up and place frame 111 contacts the L-shaped limit plate 124 and cannot rotate under the action of the torsion spring between the pick-up and place frame 111 and the drive shaft 117. That is, the torsion spring between the pick-up and place frame 111 and the drive shaft 117 is compressed, and the drive shaft 117 rotates relative to the pick-up and place frame 111. The adjustment gear 118 rotates clockwise in sync, which causes the adjustment rack 112 to move downward and the long arm slide plate 109 to move downward in sync.

[0031] refer to Figure 3 The adjustment motor 116 is started to drive the transmission shaft 117 to rotate counterclockwise. Under the action of the torsion spring between the pick-up and place-up rotating frame 111 and the transmission shaft 117, the pick-up and place-up rotating frame 111 rotates synchronously. That is, the long arm slide plate 109, the adjustment rack 112, and the adjustment gear 118 rotate synchronously, so that the pick-up and place-up rotating frame 111 rotates 180 degrees relative to the fan-shaped ring plate 106. At this time, the long arm slide plate 109 is located directly above the conveying group 102, and the other side of the pick-up and place-up rotating frame 111 contacts the L-shaped limit plate 124 and cannot continue to rotate. The transmission shaft 117 continues to rotate. Under the action of the adjustment rack 112 and the adjustment gear 118, the long arm slide plate 109 continues to move downward, so that the suction cup 110 contacts the glass cover plate conveyed on the conveying group 102.

[0032] The base 101 is provided with a support assembly, which includes a support frame 108. The support frame 108 is fixedly installed on the base 101. Semicircular support plates 105 are symmetrically slidably installed on the support frame 108. Springs are provided between the semicircular support plates 105 and the support frame 108. When the two semicircular support plates 105 are joined, they form a complete circular plate. The circular plate formed when the two semicircular support plates 105 are joined is provided with a groove to accommodate the movement of the long-arm sliding plate 109. When the two semicircular support plates 105 are joined and the long-arm sliding plate 109 is in a horizontal state, the axis of the circular plate formed by the two semicircular support plates 105 and the axis of the suction cup 110 on the long-arm sliding plate 109 are on the same straight line.

[0033] In the initial position, the spring between the semicircular support plate 105 and the support frame 108 is not compressed. At this time, the two semicircular support plates 105 are joined to form a complete circular plate. When the end of the long arm slide plate 109 furthest from the fan-shaped ring plate 106 is at the furthest from the conveyor group 102, the long arm slide plate 109 is directly above the circular plate. At this time, when the torsion spring between the pick-and-place rotating frame 111 and the drive shaft 117 is not compressed, the lower surface of the long arm slide plate 109 is above the upper surface of the circular plate. The drive shaft 117 is driven to rotate relative to the pick-and-place rotating frame 111, and the long arm slide plate 109 moves downward. That is, the long arm slide plate 109 moves downward through the groove on the circular plate formed by the two semicircular support plates 105, so that the upper surface of the long arm slide plate 109 and the upper surface of the circular plate are on the same plane.

[0034] An unfolding unit is provided between the two semicircular support plates 105. The unfolding unit is used to adjust the position between the two semicircular support plates 105. The unfolding unit includes a circular rotating frame 128 and a linkage gear 132 rotatably mounted on the base 101. An unfolding motor 131 is fixedly mounted on the base 101. The output shaft of the unfolding motor 131 is fixedly connected to the circular rotating frame 128. Two sector-shaped linkage racks 133 are fixedly arranged in a circular array on the inner side of the circular rotating frame 128. When the sector-shaped linkage racks 133 and the linkage gear 132 are engaged, they form a gear rack pair. A strip-shaped push plate 129 is rotatably mounted on the support frame 108. An unfolding slide plate 127 is fixedly installed at the end closest to the circular rotating frame 128. A strip push plate 129 is used to push the two unfolding slide plates 127 to move. The strip push plate 129 is located between the two unfolding slide plates 127. There is friction between the strip push plate 129 and the support frame 108. When the strip push plate 129 is not subjected to external force, the strip push plate 129 cannot rotate relative to the support frame 108. An unfolding gear 130 is fixedly installed on the strip push plate 129. The unfolding gear 130 and the linkage gear 132 engage to form a gear pair. The axis of the unfolding gear 130 and the center line of the circular rotating frame 128 are on the same straight line.

[0035] Initially, the strip pusher 129 is vertical. The unfolding motor 131 is activated, driving the circular rotating frame 128 to rotate. The two sector-shaped linkage racks 133 rotate synchronously. When one of the sector-shaped linkage racks 133 contacts the linkage gear 132, the circular rotating frame 128 continues to rotate. Under the action of this sector-shaped linkage rack 133, the linkage gear 132 rotates, causing the unfolding gear 130 to rotate. This, in turn, causes the strip pusher 129 to rotate against the friction between the strip pusher 129 and the support frame 108. During the rotation of the strip pusher 129, both ends of the strip pusher 129 contact the unfolding slide plates 127 on both sides. The continued rotation of the strip pusher 129 causes the two unfolding slide plates 127 to move away from each other, and the two semi-circular support plates 105 to move away from each other. The spring between the semi-circular support plate 105 and the support frame 108 is compressed. The sector-shaped linkage rack 133 disengages from the linkage gear... When wheel 132 engages, under the action of unfolding gear 130 and linkage gear 132, the strip pusher 129 rotates 90 degrees relative to unfolding motor 131. At this time, the strip pusher 129 is in a horizontal state, that is, the two semicircular support plates 105 are at their farthest positions. When the sector linkage rack 133 disengages from the linkage gear 132, under the action of friction between the strip pusher 129 and support frame 108, the position of the strip pusher 129 will not move, and the circular rotating frame 128... As the rotation continues, another sector-shaped linkage rack 133 contacts the linkage gear 132, driving the linkage gear 132 to rotate. When the sector-shaped linkage rack 133 disengages from the linkage gear 132, the strip push plate 129 rotates 90 degrees and is in a vertical state. That is, under the action of the circular rotating frame 128, the unfolding gear 130, the linkage gear 132, and the two sector-shaped linkage racks 133, the strip push plate 129 rotates 90 degrees twice during the 360-degree rotation of the circular rotating frame 128.

[0036] A transmission gear 125 is rotatably mounted on the base 101. The transmission gear 125 is fixedly connected to the shift gear 114 closest to the transmission gear 125. Two sector-shaped transmission racks 126 are fixedly arranged in a circular array on the circular rotating frame 128. When the sector-shaped transmission racks 126 engage with the transmission gear 125, they form a gear rack pair.

[0037] In the initial position, the opening of the sector ring plate 106 is vertically upward. Under the action of its own weight, the sector ring plate 106 cannot rotate relative to the sector support base 134 when it is not subjected to external force.

[0038] During the rotation of the circular rotating frame 128, when the sector-shaped linkage rack 133 drives the linkage gear 132, the sector-shaped transmission racks 126 do not contact the transmission gear 125. When the sector-shaped linkage rack 133 disengages from the linkage gear 132, one of the two sector-shaped transmission racks 126 contacts the transmission gear 125. The circular rotating frame 128 continues to rotate. At this time, the position of the strip push plate 129 does not move. Under the action of the sector-shaped transmission racks 126, the transmission gear 125 rotates, causing the shift gear 114 to rotate, which in turn causes the sector-shaped ring plate 106 to rotate. During the rotation of the transmission gear 125 driven by the sector-shaped transmission racks 126, the sector-shaped linkage racks 133 do not contact the linkage gear 132. When the 6-axis disengages from the transmission gear 125, the sector-shaped transmission rack 126 rotates 180 degrees. At this time, the opening of the sector-shaped ring plate 106 is at the position closest to the lower surface of the base 101. That is, under the action of the sector-shaped shift rack 113, shift gear 114, sector-shaped transmission rack 126, circular rotating frame 128, unfolding gear 130, unfolding motor 131, linkage gear 132, and sector-shaped linkage rack 133, the strip push plate 129 first rotates 90 degrees, then causes the sector-shaped ring plate 106 to rotate 180 degrees, then causes the strip push plate 129 to rotate 90 degrees, and finally causes the sector-shaped ring plate 106 to rotate 180 degrees. During the rotation of the sector-shaped ring plate 106, the strip push plate 129 will not rotate, and during the rotation of the strip push plate 129, the sector-shaped ring plate 106 will not rotate.

[0039] The base 101 is also equipped with auxiliary components, including an air knife 107 slidably mounted on the base 101, an air pump 120 fixedly mounted on the air knife 107, the air pump 120 and the air knife 107 being connected, an auxiliary lead screw 119 fixedly mounted on the side of the air knife 107, an auxiliary pulley 121 rotatably mounted on the base 101, the auxiliary pulley 121 and the auxiliary lead screw 119 forming a helical pair, an auxiliary motor 122 fixedly mounted on the base 101, a pulley fixedly mounted on the output shaft of the auxiliary motor 122, and a belt between the pulley on the output shaft of the auxiliary motor 122 and the auxiliary pulley 121. The air knife 107 is used to clean the surface of the glass cover. The base 101 is also symmetrically equipped with scanners 104, the two scanners 104 being symmetrically arranged with respect to the axis of the circular plate formed when the two semi-circular support plates 105 are joined. The scanners 104 are used to scan and detect defects on the surface of the glass cover.

[0040] Working principle: The starting adjustment motor 116 drives the pick-and-place rotating frame 111 and the drive shaft 117 to rotate, causing the long arm slide plate 109 to rotate directly above the conveying group 102. The conveying group 102 then transports the glass cover plate to be inspected directly below the suction cup 110 on the long arm slide plate 109. The drive shaft 117 continues to rotate, and under the action of the adjustment rack 112 and the adjustment gear 118, the suction cup 110 contacts the glass cover plate. Then, the vacuum pump 123 is started, causing the suction cup 110 to... The glass cover is adsorbed, and then the adjustment motor 116 is started to drive the transmission shaft 117 to rotate in the opposite direction, so that the long arm slide plate 109 rotates to be directly above the circular plate formed by the two semi-circular support plates 105. The transmission shaft 117 continues to rotate, and the long arm slide plate 109 moves downward, so that the lower surface of the glass cover adsorbed by the suction cup 110 contacts the upper surface of the circular plate formed by the two semi-circular support plates 105, so that the circular plate formed by the two semi-circular support plates 105 supports the lower surface of the glass cover.

[0041] Then, the auxiliary motor 122 is started to drive the auxiliary pulley 121 to rotate. Under the action of the auxiliary lead screw 119, the air knife 107 moves away from the auxiliary motor 122, thereby moving the air knife 107 from above the glass cover. The air pump 120 is started to blow the dust off the surface of the glass cover by the air knife 107. With the support of the semi-circular support plate 105, the glass cover is prevented from being bent and damaged by the air knife 107. Then, the defects on the surface of the glass cover are scanned and detected by the scanner 104.

[0042] If the surface of the glass cover plate passes inspection, the adjustment motor 116 is activated to return the long arm slide plate 109 to its initial position. Then, the unfolding motor 131 is activated. Under the action of the unfolding gear 130, the linkage gear 132, and the sector linkage rack 133, the strip push plate 129 rotates to a horizontal position, causing the two semicircular support plates 105 to rotate to their furthest positions, thus making way for the long arm slide plate 109 to rotate the glass cover plate. The circular rotating frame 128 continues to rotate. Under the action of the shift gear 114, the transmission gear 125, and the circular rotating frame 128, the sector ring plate 106 rotates 180 degrees, causing the long arm slide plate 109 to rotate 180 degrees. Then, the adjustment motor 116 is activated to move the long arm slide plate 109 upward, so that the glass cover plate is now above the upper surface of the semicircular support plate 105. The unfolding motor is then activated again. 131 drives the strip pusher 129 to rotate 90 degrees, causing the two semi-circular support plates 105 to rejoin to form a circular plate. Then, the adjustment motor 116 is started to place the glass cover plate onto the semi-circular support plate 105 using the long arm slide plate 109. The long arm slide plate 109 is then moved to the position furthest from the axis of the fan-shaped ring plate 106. The unfolding motor 131 is then started to drive the fan-shaped ring plate 106 to rotate 180 degrees, so that the upper surface of the long arm slide plate 109 is at the position furthest from the lower surface of the base 101. Then, the adjustment motor 116 is started to move the long arm slide plate 109 downwards, so that the suction cup 110 on the long arm slide plate 109 contacts the lower surface of the glass cover plate. The above steps are then repeated, causing the air knife 107 to blow away the dust on the surface. Finally, the scanner 104 scans and detects the defects on the surface.

[0043] If the inspection of one side is still qualified, the inspection of defects on both sides of the glass cover is completed. Then, the adjustment motor 116 is started to put the glass cover back onto the conveyor belt in the conveyor group 102. If the inspection of one side is unqualified, the two semi-circular support plates 105 are moved to the farthest position and the glass cover is dropped. Repeat the above steps to achieve continuous inspection of the glass cover.

[0044] This invention is not limited to the specific embodiments described above. Any modifications made by those skilled in the art based on the above concept without creative effort are within the protection scope of this invention.
