Description

Technical Field

[0001] This invention relates to the field of testing equipment technology, and in particular to a device for detecting scratches on the surface of vehicle-mounted touch glass. Background Technology

[0002] With the widespread application of automotive touchscreen glass in smart cars, its surface quality has an increasingly significant impact on user experience and driving safety. Surface scratches not only affect aesthetics but can also interfere with touch sensitivity and display clarity. Currently, common scratch detection methods mostly rely on manual visual inspection or traditional optical equipment, which are easily affected by ambient light, dust, and other factors, leading to unstable detection accuracy. Especially when there is electrostatically adsorbed micro-dust on the glass surface, it is easily misjudged as scratches, seriously affecting detection accuracy. In addition, existing cleaning methods are inefficient and cannot achieve continuous, dust-free operation during the detection process, causing interruptions in the detection process and affecting overall efficiency. Therefore, this invention provides a surface scratch detection device for automotive touchscreen glass. Summary of the Invention

Detailed Implementation

[0033] 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.

[0034] Example: Reference Figures 1-18 A device for detecting scratches on the surface of automotive touch glass includes a base plate 101. A square vacuum suction plate 102, a conveyor belt 105, a multi-axis robot arm 106, and a scanner 116 are mounted on the base plate 101. A lifting cylinder 103 is fixedly installed on the base plate 101. The square vacuum suction plate 102 is fixedly installed at the piston rod end of the lifting cylinder 103. A vacuum generator 107 is also fixedly installed on the lower surface of the square vacuum suction plate 102. A switching frame 104 is fixedly installed on the base plate 101. The conveyor belt 105 is used to transport the automotive touch glass to be inspected. The multi-axis robot arm 106 is used to transfer the automotive touch glass onto the square vacuum suction plate 102. The multi-axis robot arm 106 transfers the automotive touch glass from the conveyor belt 105 to the center position of the square vacuum suction plate 102, making the sides of the automotive touch glass parallel to the sides of the square vacuum suction plate 102. Then, the vacuum generator 107 is activated to control the square vacuum suction plate 102 to adsorb and fix the automotive touch glass.

[0035] An auxiliary slide 112 is slidably mounted on the switching base 104, and an auxiliary lead screw 113 is rotatably mounted on the switching base 104. The auxiliary lead screw 113 and the auxiliary slide 112 form a helical pair. An auxiliary motor 114 is fixedly mounted on the switching base 104, and the output shaft of the auxiliary motor 114 is fixedly connected to the auxiliary lead screw 113. The scanner 116 is fixedly mounted on the auxiliary slide 112, and a high-pressure ion air bar 115 is fixedly mounted on the auxiliary slide 112. An ion generator is provided inside the high-pressure ion air bar 115. There is a distance between the high-pressure ion air bar 115 and the scanner 116, and the distance between the high-pressure ion air bar 115 and the scanner 116 is greater than the length of the square vacuum suction plate 102.

[0036] After the square vacuum suction plate 102 completes the adsorption and fixation of the touch glass, the lifting cylinder 103 is activated to drive the square vacuum suction plate 102 to move upward. The touch glass on the square vacuum suction plate 102 moves upward synchronously, so that the touch glass contacts the lower end of the high-pressure ion air bar 115. Then, the auxiliary motor 114 is activated to drive the auxiliary lead screw 113 to rotate, so that the auxiliary slide 112 moves relative to the switching base 104. At this time, the auxiliary slide 112 moves along the long side of the square vacuum suction plate 102. The high-pressure ion air bar 115 and the scanner 116 on the auxiliary slide 112 move synchronously, and the high-pressure ion air bar 115 is activated. The high-pressure ion air bar 115 compresses air to generate a high-speed airflow to blow away the dust on the surface of the touch glass. At the same time, the ion generator built into the high-pressure ion air bar 115 generates positive and negative ions to neutralize the static electricity of the dust. The airflow blows away the dust, and the ion neutralization prevents it from being adsorbed again.

[0037] By activating the auxiliary motor 114 to drive the auxiliary carriage 112 to move laterally, the scanner 116 can be moved laterally. Under the action of the scanner 116, the scratches on the touch glass on the square vacuum suction plate 102 can be scanned and detected.

[0038] A switching assembly is provided on the base plate 101. The switching assembly includes a switching base frame 104. A conveyor belt 105 is fixedly installed on the base plate 101. Two adhesive units are provided on the switching base frame 104. Each adhesive unit includes an adhesive straight plate 123. A take-up turntable 124 is symmetrically rotatably mounted on each adhesive straight plate 123. A dust-adhesive roll paper 108 is provided between the two take-up turntables 124 on the same adhesive straight plate 123. A take-up cylinder 131 is provided on each take-up turntable 124. The two ends of the dust-adhesive roll paper 108 are respectively connected to the corresponding take-up cylinder 131. A nut 132 is provided between the take-up cylinder 131 and the corresponding take-up turntable 124. The take-up cylinder 131 is fixed to the corresponding take-up turntable 124 by the nut 132. A transmission assembly is provided between the two take-up turntables 124 on the same adhesive straight plate 123.

[0039] The transmission assembly includes a transmission belt 133 and two transmission pulleys 135. The transmission pulleys 135 are fixedly mounted on the corresponding take-up turrets 124. The transmission belt 133 is positioned between the two transmission pulleys 135. A take-up and discharge motor 134 is also fixedly mounted on the take-up plate 123, and its output shaft is fixedly connected to the corresponding take-up turret 124.

[0040] refer to Figure 5When the take-up and unwind machine 134 is started, the two take-up turrets 124 rotate synchronously under the action of the drive belt 133 and drive pulley 135. Both take-up turrets 124 rotate counterclockwise. The left take-up turret 124 unwinds the sticky paper roll 108, and the right take-up turret 124 winds it up. After the sticky paper roll 108 on the left side is unwound, the take-up turret 124 can be unwound by removing the nut 132 on the take-up turret 124. The two take-up cylinders 131 are removed, and then the take-up cylinder 131 containing the unused adhesive paper roll 108 is installed on the left take-up rotary table 124. The unwound take-up cylinder 131 is installed on the right take-up rotary table 124, and the end of the adhesive paper roll 108 on the left take-up rotary table 124 is pulled and wound onto the take-up cylinder 131 on the right take-up rotary table 124, thus realizing the replacement of the adhesive paper roll 108 on the take-up rotary table 124.

[0041] An auxiliary bracket 125 is also fixedly installed on the switching base 104. Vertical strips 127 and horizontal strips 126 are symmetrically fixed on the auxiliary bracket 125. The horizontal strips 126 and vertical strips 127 are perpendicular to each other. Vertical grooves 128 that cooperate with the vertical strips 127 are symmetrically provided on the picking plate 123. Horizontal grooves 129 that cooperate with the horizontal strips 126 are also symmetrically provided on the picking plate 123.

[0042] The switching base 104 is also equipped with a first sliding carriage 137, a second sliding carriage 139, a lowering carriage 141, and a lifting carriage 142. Circular electromagnets 148 are symmetrically fixed on both the first sliding carriage 137 and the second sliding carriage 139. An L-shaped lowering plate 155 is fixedly fixed on the lowering carriage 141, and a strip electromagnet 152 is symmetrically fixed on the lifting carriage 142. The circular electromagnets 148, the strip electromagnets 152, and the L-shaped lowering plate 155 are used to switch the pick-up unit.

[0043] Both the first sliding carriage 137 and the second sliding carriage 139 are slidably mounted on the switching base 104. The directions of movement of the first sliding carriage 137 and the second sliding carriage 139 relative to the switching base 104 are parallel, and the directions of movement of the first sliding carriage 137 and the second sliding carriage 139 relative to the switching base 104 are parallel to the direction of movement of the picking plate 123 relative to the transverse strip 126. The second sliding carriage 139 is located above the first sliding carriage 137. The first sliding carriage 137 is arranged horizontally, and the second sliding carriage 139 is arranged vertically. A first sliding screw 138 is rotatably mounted on the first sliding carriage 137. 8 and the switching base 104 form a helical pair. The first push screw 138 and the first push slide 137 form a helical pair. The second push screw 140 is rotatably mounted on the switching base 104. The second push slide 139 and the second push screw 140 form a helical pair. The axes of the first push screw 138 and the second push screw 140 are parallel. The second push motor 147 is fixedly mounted on the switching base 104. The output shaft of the second push motor 147 is fixedly connected to the second push screw 140. The first push motor 146 is fixedly mounted on the first push slide 137. The output shaft of the first push motor 146 is fixedly connected to the first push screw 138.

[0044] When the two circular electromagnets 148 on the pusher slide 137 come into contact with the pick-up plate 123, the pick-up plate 123 and the pusher slide 137 form a whole under the action of the circular electromagnets 148. The pusher motor 146 is started to drive the pusher screw 138 to rotate, so that the pusher slide 137 moves relative to the switching base 104. The pick-up plate 123 on the pusher slide 137 moves synchronously. When the pick-up plate 123 moves under the action of the pusher slide 137, the transverse groove 129 above the pick-up plate 123 will engage with the transverse strip 126 below the auxiliary support 125 during the movement. Under the action of the auxiliary support 125 and the transverse groove 129, the stability of the pusher slide 137 pushing the pick-up plate 123 is improved.

[0045] When the two circular electromagnets 148 on the second pusher slide 139 come into contact with the pick-up plate 123, the pick-up plate 123 and the second pusher slide 139 form a whole under the action of the circular electromagnets 148. The second pusher motor 147 is started to drive the second pusher screw 140 to rotate, so that the second pusher slide 139 moves relative to the switching base frame 104. The pick-up plate 123 on the second pusher slide 139 moves synchronously. When the pick-up plate 123 moves under the action of the second pusher slide 139, the transverse groove 129 below the pick-up plate 123 will engage with the transverse strip 126 above the auxiliary support 125 during the movement. Under the action of the auxiliary support 125 and the transverse groove 129, the stability of the second pusher slide 139 pushing the pick-up plate 123 is improved.

[0046] The lower slide 141 is slidably mounted on the switching base 104. The direction of movement of the lower slide 141 relative to the switching base 104 is perpendicular to the direction of movement of the push slide 137 relative to the switching base 104. A lower lead screw 150 is rotatably mounted on the switching base 104. The lower lead screw 150 and the lower slide 141 form a helical pair. A lower motor 149 is fixedly mounted on the switching base 104. The output shaft of the lower motor 149 is fixedly connected to the lower lead screw 150. An L-shaped lower plate 155 is fixedly mounted on the lower surface of the lower slide 141. A square groove 130 that mates with the lower end of the L-shaped lower plate 155 is also provided on the pick-up straight plate 123.

[0047] When the lower end of the L-shaped lowering plate 155 engages with the square groove 130 on the picking plate 123, the lowering motor 149 is started to drive the lowering screw 150 to rotate, which causes the lowering slide 141 to move up and down relative to the switching base 104. The L-shaped lowering plate 155 moves synchronously, which in turn causes the picking plate 123 engaged with the L-shaped lowering plate 155 to move synchronously. When the picking plate 123 moves under the action of the L-shaped lowering plate 155, the two vertical grooves 128 on the picking plate 123 will engage with the vertical strip 127 on the auxiliary support 125 during the movement. Under the action of the vertical strip 127 and the vertical groove 128, the stability of the L-shaped lowering plate 155 pushing the picking plate 123 to move is improved.

[0048] The lifting slide 142 is also slidably mounted on the switching base 104. The direction of movement of the lifting slide 142 relative to the switching base 104 is parallel to the direction of movement of the lowering slide 141 relative to the switching base 104. A lifting screw 143 is rotatably mounted on the switching base 104. The lifting screw 143 and the lifting slide 142 form a helical pair. A lifting motor 144 is fixedly mounted on the switching base 104. The output shaft of the lifting motor 144 is fixedly connected to the lifting screw 143. Two bar electromagnets 152 are symmetrically rotatably mounted on the lifting slide 142. A transmission group 2 is provided between the two bar electromagnets 152. A linkage block 136 is also symmetrically fixed on the picking plate 123. A straight groove that cooperates with the bar electromagnet 152 is provided on each linkage block 136.

[0049] The second transmission assembly includes a transmission shaft 122, two transmission belts 151, two driven pulleys 153, and two transmission pulleys 154. The transmission shaft 122 is rotatably mounted on the lifting slide 142. The two transmission pulleys 154 are symmetrically fixed at both ends of the transmission shaft 122. The two driven pulleys 153 are respectively fixedly mounted on corresponding bar electromagnets 152. The transmission belts 151 are arranged between the corresponding driven pulleys 153 and the transmission pulleys 154. A tilting motor 145 is also fixedly mounted on the bar electromagnet 152. The output shaft of the tilting motor 145 is fixedly connected to the transmission shaft 122.

[0050] Initially, the lifting carriage 142 is located closest to the base plate 101, and the bar electromagnets 152 are all horizontal. The push motor 146 is activated, driving the push carriage 137 to move away from the multi-axis manipulator 106. The transverse groove 129 on the picking plate 123 slides relative to the corresponding transverse bar 126. During the movement, the linkage block 136 on the picking plate 123 rotates, with its linear groove and the bar electromagnets 152 rotating. When the bar electromagnets 152 and the linkage block 136 are fully engaged, the picking plate 123... The transverse slide 129 on plate 23 disengages from the transverse strip 126. At this time, the axis of the linkage block 136 on the picking plate 123 and the axis of the corresponding driven pulley 153 are on the same straight line. At this time, the bar electromagnet 152 is activated to attract and fix the linkage block 136. That is, the bar electromagnet 152 and the picking plate 123 form a whole. Then, the circular electromagnet 148 on the push carriage 137 is turned off, and the push motor 146 is activated to move the push carriage 137 to the position furthest from the multi-axis robot 106, which makes way for the subsequent movement of the picking plate 123.

[0051] Then, the flip motor 145 is started. Under the action of the transmission belt 151, the transmission pulley 154, and the transmission shaft 122, the two driven pulleys 153 rotate synchronously. Under the action of the bar electromagnet 152, the pick-up plate 123 rotates synchronously, first causing the pick-up plate 123 to rotate 180 degrees. At this time, the take-up turntable 124 on the pick-up plate 123 is horizontally facing the outside of the switching base frame 104. Then, the lifting motor 144 is started to drive the lifting screw 143 to rotate, causing the lifting slide 142 to move upward. Under the action of the bar electromagnet 152 and the linkage block 136, the linkage block 136 moves upward synchronously. At this time, the flip motor 145 is started again to drive the pick-up plate 123 to continue to rotate 180 degrees. At this time, the take-up turntable 124 on the pick-up plate 123 is horizontally facing the multi-axis robot arm 106 again. Under the action of the transmission group 2, the rotation of the pick-up plate 123 is avoided.

[0052] In operation, the adhesive strip 123 corresponding to the adhesive roll 108 in use is located at the position closest to the base plate 101 and the position closest to the multi-axis robot arm 106. The adhesive strip 123 is fixed under the action of the circular electromagnet 148 on the first push carriage 137 and the L-shaped downward moving plate 155, and the adhesive strip 123 is not in contact with the horizontal strip 126 and the vertical strip 127. The adhesive strip 123 with the spare adhesive roll 108 is located at the position farthest from the base plate 101. The adhesive strip 123 is fixed under the circular electromagnet 148 on the second push carriage 139. The horizontal slide 129 below the adhesive strip 123 and the horizontal strip 126 on the auxiliary support 125 are in an engaged state, thereby improving the stability of the adhesive strip 123 when idle.

[0053] When the adhesive paper roll 108 on the adhesive plate 123 closest to the base plate 101 is used up, the lifting motor 144 is first started to move the lifting carriage 142 to the position closest to the base plate 101, so that the bar electromagnet 152 can dock with the linkage block 136 on the adhesive plate 123. Then, the push motor 146 is started to move the push carriage 137 away from the multi-axis robot arm 106, the adhesive plate 123 disengages from the L-shaped lower plate 155 and engages with the transverse strip 126. Even if the linkage block 136 on the picking plate 123 is connected to the bar electromagnet 152, the picking plate 123 is disengaged from the auxiliary support 125. The bar electromagnet 152 is activated to attract and fix the linkage block 136. Then, the push carriage 137 is moved to the position furthest from the picking plate 123 to make way. Then, the flip motor 145 is activated to drive the picking plate 123 to rotate 180 degrees. At this time, the winding turntable 124 on the picking plate 123 faces the outside of the switching base frame 104.

[0054] Then, the lifting motor 144 is restarted to drive the lifting carriage 142 upward a certain distance, allowing the first pushing carriage 137 to return to the position closest to the multi-axis robot 106. The lowering motor 149 is then started to move the lowering carriage 141 to the position furthest from the base plate 101, and the L-shaped lowering plate 155 moves synchronously. Then, the second pushing motor 147 is started to move the second pushing carriage 139 closer to the multi-axis robot 106, finally moving the picking plate 123 on the second pushing carriage 139 to the position closest to the multi-axis robot 106. At this time, the square groove 130 on the picking plate 123 engages with the L-shaped lowering plate 155, and the pushing carriage... The circular electromagnet 148 on the second 139 contacts and fixes the adhesive strip 123. Then, the downward moving motor 149 is started, causing the L-shaped downward moving plate 155 to move downward. The adhesive strip 123 moves downward synchronously and engages with the vertical strip 127. Finally, the adhesive strip 123 moves to the position closest to the bottom plate 101. At this time, the adhesive strip 123 disengages from the vertical strip 127. Then, the circular electromagnet 148 on the first pusher slide 137 is started to fix the adhesive strip 123, thus realizing the rapid switching of the dust-adhesive roll paper 108 on the spare adhesive strip 123, thereby ensuring the working efficiency of the equipment.

[0055] At this point, the second pusher slide 139 is moved to the position furthest from the multi-axis robot 106, thus making way for the movement of the adhesive strip 123 on the lifting slide 142. Then, the lifting motor 144 is started again to move the lifting slide 142 to the position furthest from the base plate 101. Then, the adhesive roll paper 108 on the adhesive strip 123 is replaced. Then, the flipping motor 145 is started to drive the adhesive strip 123 to rotate 180 degrees. At this time, the take-up turntable 124 on the adhesive strip 123 is horizontally facing the multi-axis robot 106. Then, the circular electromagnet 148 on the second pusher slide 139 is used to attract and fix the adhesive strip 123, and pushes the adhesive strip 123 to engage with the transverse strip 126. That is, at this time, the adhesive strip 123 becomes a new spare.

[0056] A rolling and bonding assembly is provided on the base plate 101. The rolling and bonding assembly includes a rolling and bonding slide 109, which is slidably mounted on the base plate 101. A downward pressure screw 110 is rotatably mounted on the base plate 101. The downward pressure screw 110 and the rolling and bonding slide 109 form a helical pair. A downward pressure motor 111 is fixedly mounted on the base plate 101. The output shaft of the downward pressure motor 111 is fixedly connected to the downward pressure screw 110. When the downward pressure motor 111 is started, it drives the downward pressure screw 110 to rotate, which causes the rolling and bonding slide 109 to move up and down relative to the base plate 101.

[0057] A downward pressing rod 117 is symmetrically and rotatably mounted on the adhesive roller slide 109. The downward pressing rod 117 is used to open the adhesive roll paper 108. An elastic roller 120 is also movably mounted on the adhesive roller slide 109. The elastic roller 120 is used to roll the adhesive roll paper 108. A rolling slide 118 is slidably mounted on the adhesive roller slide 109. The elastic roller 120 is rotatably mounted on the rolling slide 118. The elastic roller 120 is located between the two rolling motors 121. The roller is equipped with a rolling screw 119, which forms a helical pair with the rolling slide plate 118. A rolling motor 121 is also fixedly installed on the rolling and sticking slide 109. The output shaft of the rolling motor 121 is fixedly connected to the rolling screw 119. When the rolling motor 121 is started, it drives the rolling screw 119 to rotate, which causes the rolling slide plate 118 to move laterally relative to the rolling and sticking slide 109. The elastic roller 120 moves synchronously, that is, the elastic roller 120 moves between the two pressing round rods 117.

[0058] Before replacing the adhesive roll 108 with the switching assembly, the pressing motor 111 is started to move the roller slide 109 to the position furthest from the base plate 101. At this time, the positions of the pressing rod 117 and the elastic roller 120 will not affect the movement of the switching assembly. After the replacement of the adhesive roll 108 is completed, the pressing motor 111 is started to drive the roller slide 109 to move downward. The components on the roller screw 119 move downward synchronously. Both pressing rods 117 contact the upper surface of the adhesive roll 108 between the two take-up turntables 124. Under the action of the two pressing rods 117, the adhesive roll 108 between the two pressing rods 117 forms a horizontal plane, and the elastic roller 120 also contacts the upper surface of the adhesive roll 108, finally causing the pressing rod 117 to move to the designated position.

[0059] After the high-pressure ionizing air bar 115 cleans the touch glass on the square vacuum suction plate 102, the auxiliary motor 114 and the high-pressure ionizing air bar 115 move to both sides of the square vacuum suction plate 102. Then, the lifting cylinder 103 is activated to drive the square vacuum suction plate 102 to move upward, so that the touch glass contacts the lower surface of the adhesive roll paper 108 between the two pressing round rods 117. Then, the rolling motor 121 is activated to drive the elastic roller 120 to move laterally, that is, the elastic roller 120 rolls above the touch glass, so that the adhesive roll paper 108 can fully contact the surface of the touch glass. After the elastic roller 120 completes rolling, the lifting cylinder 103 is activated to move the square vacuum suction plate 102 downward. Under the action of the adhesive roll paper 108, the dust on the surface of the touch glass is removed. Then, the scanner 116 scans and detects the scratches on the surface of the touch glass. Finally, the receiver-discharge motor 134 is activated to replace the adhesive roll paper 108 between the two pressing round rods 117.

[0060] Working principle: The multi-axis robot 106 transfers the touch glass to be inspected from the conveyor belt 105 to the center of the square vacuum suction plate 102. Then, the vacuum generator 107 causes the square vacuum suction plate 102 to adhere and fix the touch glass. Then, the high-pressure ion air bar 115 blows off most of the dust on the surface of the touch glass. Then, the lifting cylinder 103 is activated to move the touch glass upward to contact the adhesive paper roll 108. The elastic roller 120 ensures that the adhesive paper roll 108 completely adheres to the touch glass. Then, the lifting cylinder 103 is activated again to move the touch glass downward. Under the action of the adhesive paper roll 108, the dust on the surface of the touch glass is cleaned. After cleaning, the touch glass is scanned and inspected by the scanner 116. After inspection, the touch glass is placed back onto the conveyor belt 105 by the multi-axis robot 106.

[0061] When the adhesive tape roll 108 in use runs out, the two adhesive units can be switched by switching the switching component, so as to call up the spare adhesive tape roll 108 and thus ensure the overall working efficiency of the device.

[0062] 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.
