[0031] refer to Figure 3 , start the positioning motor 116 to drive the transmission shaft 117 to rotate counterclockwise. Under the action of the torsion spring between the pick-up and place turntable 111 and the transmission shaft 117, the pick-up and place turntable 111 rotates synchronously, that is, the long arm slide 109, the positioning rack 112, and the positioning gear 118 rotate synchronously, and finally the pick-up and place turntable 111 rotates 180 degrees relative to the fan-shaped ring plate 106. At this time, the long arm slide 109 is located directly above the conveying group 102, and at this time, the other side of the pick-up and place turntable 111 contacts the L-shaped limit plate 124 and cannot continue to rotate. The transmission shaft 117 continues to rotate, and under the action of the positioning rack 112 and the positioning gear 118, the long arm slide 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, and the support assembly includes a support frame 108, which is fixedly mounted on the base 101, and a semicircular support plate 105 is symmetrically slidably mounted on the support frame 108, and springs are arranged between the semicircular support plate 105 and the support frame 108, and a complete circular plate is formed when the two semicircular support plates 105 are joined, and a sliding groove for accommodating the movement of the long arm skateboard 109 is arranged on the circular plate formed when the two semicircular support plates 105 are joined. When the two semicircular support plates 105 are joined and the long arm skateboard 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 skateboard 109 are in 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 combined to form a complete circular plate. When the end of the long arm skateboard 109 farthest from the fan-shaped ring plate 106 is located at the farthest position from the conveying group 102, the long arm skateboard 109 is located directly above the circular plate, and at this time, when the torsion spring between the pick-up and place turntable 111 and the transmission shaft 117 is not compressed, the lower surface of the long arm skateboard 109 is located above the upper surface of the circular plate, and the drive shaft 117 is driven to rotate relative to the pick-up and place turntable 111, and the long arm skateboard 109 moves downward, that is, the long arm skateboard 109 moves downward through the slide groove on the circular plate formed by the two semicircular support plates 105, and finally the upper surface of the long arm skateboard 109 and the upper surface of the circular plate are on the same plane.

[0034] An unfolding unit is arranged between the two semicircular support plates 105, and 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, and the output shaft of the unfolding motor 131 is fixedly connected to the circular rotating frame 128. Two fan-shaped linkage racks 133 are fixedly arranged on the inner circumferential array of the circular rotating frame 128. When the fan-shaped linkage rack 133 and the linkage gear 132 are engaged, a gear rack pair is formed. A strip push plate 129 is rotatably mounted on the support frame 108, and the semicircular support plates 105 are rotated. 05 An unfolding slide 127 is fixedly provided at the end closest to the circular rotating frame 128. The strip push plate 129 is used to push the two unfolding slides 127 to move. The strip push plate 129 is located between the two unfolding slides 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 are engaged 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] When the strip push plate 129 is in the initial position, the strip push plate 129 is in a vertical state, and the unfolding motor 131 is started to drive the circular rotating frame 128 to rotate, and the two fan-shaped linkage racks 133 rotate synchronously. When one of the two fan-shaped linkage racks 133 contacts the linkage gear 132, the circular rotating frame 128 continues to rotate. Under the action of the fan-shaped linkage rack 133, the linkage gear 132 rotates, that is, the unfolding gear 130 rotates, thereby causing the strip push plate 129 to overcome the friction between the strip push plate 129 and the support frame 108 and rotate. During the rotation of the strip push plate 129, the two ends of the strip push plate 129 respectively contact the unfolding slide plates 127 on both sides, and the strip push plate 129 continues to rotate, that is, the two unfolding slide plates 127 move in the direction away from each other, and the two semicircular support plates 105 move in the direction away from each other. The spring between the semicircular support plate 105 and the support frame 108 is compressed, and the fan-shaped linkage rack 133 disengages from the linkage gear When the wheel 132 is engaged, under the action of the unfolding gear 130 and the linkage gear 132, the strip push plate 129 rotates 90 degrees relative to the unfolding motor 131. At this time, the strip push plate 129 is in a horizontal state, that is, at this time, the two semicircular support plates 105 are at the farthest position. When the fan-shaped linkage rack 133 is out of contact with the linkage gear 132, under the action of the friction between the strip push plate 129 and the support frame 108, the position of the strip push plate 129 will not move, and the circular rotating frame 128 Continue to rotate, so that another fan-shaped linkage rack 133 contacts the linkage gear 132 and drives the linkage gear 132 to rotate. When the fan-shaped linkage rack 133 is out of contact with 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 fan-shaped linkage racks 133, the circular rotating frame 128 rotates 360 degrees, and the strip push plate 129 rotates 90 degrees twice.

Two fan-shaped transmission racks 126 are fixedly arranged in a circular array on the circular rotating frame 128. When the fan-shaped transmission rack 126 is engaged with the transmission gear 125, a gear rack pair is formed.

[0037] In the initial position, the opening of the sector-shaped ring plate 106 is in a vertically upward position. Under the action of the deadweight of the sector-shaped ring plate 106 , the sector-shaped ring plate 106 cannot rotate relative to the sector-shaped support seat 134 when no external force is applied.

[0038] In the process of driving the circular rotating frame 128 to rotate, in the process of the sector-shaped linkage rack 133 driving the linkage gear 132, the sector-shaped transmission rack 126 does 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, and the circular rotating frame 128 continues to rotate. At this time, the position of the bar-shaped push plate 129 will not move. Under the action of the sector-shaped transmission rack 126, the transmission gear 125 rotates, that is, the transposition gear 114 rotates, and then the sector-shaped ring plate 106 rotates. In the process of the sector-shaped transmission rack 126 driving the transmission gear 125 to rotate, the sector-shaped linkage rack 133 will not contact the linkage gear 132. When the fan-shaped transmission rack 126 is out of contact with the transmission gear 125, the fan-shaped transmission rack 126 rotates 180 degrees. At this time, the opening of the fan-shaped ring plate 106 is at the position closest to the lower surface of the base 101, that is, under the action of the fan-shaped transposition rack 113, the transposition gear 114, the fan-shaped transmission rack 126, the fan-shaped transmission rack 126, the circular rotating frame 128, the unfolding gear 130, the unfolding motor 131, the linkage gear 132, and the fan-shaped linkage rack 133, the strip push plate 129 first rotates 90 degrees, then the fan-shaped ring plate 106 rotates 180 degrees, then the strip push plate 129 rotates 90 degrees, and finally the fan-shaped ring plate 106 rotates 180 degrees. During the rotation of the fan-shaped ring plate 106, the strip push plate 129 will not rotate, and during the rotation of the strip push plate 129, the fan-shaped ring plate 106 will not rotate.

[0039] An auxiliary component is also provided on the base 101, and the auxiliary component includes a wind knife 107 slidably mounted on the base 101, an air pump 120 is fixedly mounted on the wind knife 107, the air pump 120 is connected to the wind knife 107, an auxiliary screw 119 is fixedly mounted on the side of the wind knife 107, an auxiliary pulley 121 is rotatably mounted on the base 101, the auxiliary pulley 121 and the auxiliary screw 119 constitute a spiral pair, an auxiliary motor 122 is fixedly mounted on the base 101, a pulley is fixedly mounted on the output shaft of the auxiliary motor 122, a belt is arranged between the pulley on the output shaft of the auxiliary motor 122 and the auxiliary pulley 121, and the wind knife 107 is used to clean the surface of the glass cover plate. A scanner 104 is also symmetrically arranged on the base 101, and the two scanners 104 are symmetrically arranged relative to the axis of the circular plate formed when the two semicircular support plates 105 are joined, and the scanner 104 is used to scan and detect surface defects of the glass cover plate.

[0040] Working principle: Start the positioning motor 116 to drive the pick-and-place rotating frame 111 and the transmission shaft 117 to rotate, so that the long arm slide 109 rotates to the top of the conveying group 102, and the glass cover plate to be inspected is conveyed to the bottom of the suction cup 110 on the long arm slide 109 through the conveying group 102. The transmission shaft 117 continues to rotate, and under the action of the positioning rack 112 and the positioning gear 118, the suction cup 110 contacts the glass cover plate, and then the vacuum pump 123 is started to make the suction cup 110 The glass cover plate is adsorbed, and then the positioning motor 116 is started to drive the transmission shaft 117 to rotate in the opposite direction, so that the long-arm slide 109 rotates to the top of the circular plate formed by the two semicircular support plates 105. The transmission shaft 117 continues to rotate, and the long-arm slide 109 moves downward, so that the lower surface of the glass cover plate adsorbed by the suction cup 110 is in contact with the upper surface of the circular plate formed by the two semicircular support plates 105, so that the circular plate formed by the two semicircular support plates 105 supports the lower surface of the glass cover plate.

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

[0042] If the surface of the glass cover plate is qualified in the inspection, the positioning motor 116 is started to make the long arm slide plate 109 return to the initial position, and then the unfolding motor 131 is started. Under the action of the unfolding gear 130, the linkage gear 132, and the fan-shaped linkage rack 133, the strip push plate 129 is rotated to a horizontal state, that is, the two semicircular support plates 105 are rotated to the farthest position, that is, the long arm slide plate 109 drives the glass cover plate to rotate to give way, and the circular rotating frame 128 continues to rotate. Under the action of the transposition gear 114, the transmission gear 125, and the circular rotating frame 128, the fan-shaped ring plate 106 is rotated 180 degrees, that is, the long arm slide plate 109 is rotated 180 degrees, and then the positioning motor 116 is started to move the long arm slide plate 109 upward, that is, the glass cover plate at this time is moved to above the upper surface of the semicircular support plate 105, and then the unfolding motor is started. 131 drives the strip push plate 129 to rotate 90 degrees, so that the two semicircular support plates 105 are reconnected to form a circular plate, and then the positioning motor 116 is started to make the long arm slide plate 109 place the glass cover plate on the semicircular support plate 105, and then the long arm slide plate 109 is moved to the position farthest from the axis of the fan-shaped ring plate 106, and the unfolding motor 131 is continued to start 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 located at the position farthest from the lower surface of the base 101, and then the positioning motor 116 is started to make the long arm slide plate 109 move downward at this time, that is, the suction cup 110 on the long arm slide plate 109 contacts the lower surface of the glass cover plate at this time, and then the above steps are repeated to make the wind knife 107 blow off the dust on the surface, and then the scanner 104 is used to scan and detect the defects on the surface.

[0043] If the surface inspection is still qualified, that is, the inspection of defects on both sides of the glass cover plate is completed, the positioning motor 116 is started to put the glass cover plate back on the conveyor belt in the conveying group 102. If one surface inspection fails, the two semicircular support plates 105 are moved to the farthest position, and the glass cover plate is thrown down. The above steps are repeated to achieve continuous inspection of the glass cover plate.

[0044] The present invention is not limited to the above-mentioned specific implementation modes. Various changes made by technicians in the relevant technical field based on the above-mentioned conception without creative work all fall within the protection scope of the present invention.
