[0034] As described in the background art, currently cover plate manufacturers are often unable to effectively control and promptly intercept abnormal ink thickness during the production process.

[0035] In order to solve this technical problem, the utility model provides an online device for detecting the thickness of ink on a cover plate, which is applied to ink thickness detection.

[0036] Specifically, please refer to Figure 1-5 , an online device for detecting the thickness of ink on a cover plate, comprising

The surface of the ink on the cover plate is cleaned and the ink thickness is detected after cleaning to ensure the accuracy of the detection. After the detection is completed, defective products are intercepted by a rotating manipulator module, and the cover plates that exceed the set range of ink thickness are removed from the conveyor belt 103, thereby realizing online rapid automatic screening of products whose ink thickness does not meet the standard.

[0043] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0044] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0045] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0046] Please refer to Figure 1-3 , an online device for detecting the ink thickness of a cover plate, comprising: a workbench 1, a slot 101 is provided on the top of the workbench 1, and a conveyor belt 103 is provided inside the slot 101; a fixed frame 2, the fixed frame 2 is connected to the top of the workbench 1; a detection frame 3, the detection frame 3 is installed on the top of the workbench 1; a rotating manipulator module, the rotating manipulator module is located on one side of the workbench 1, a cleaning component is provided on the fixed frame 2, the cleaning component includes: a fixed block 201, a mounting block 205 and a cleaning roller 206; a detection component is provided on the detection frame 3, the detection component includes: a laser head 301, a positioning sensor 302 and a display 303, two electric rollers 102 are provided inside the slot 101, and the conveyor belt 103 is located between the two electric rollers 102, and a positioning fixture 5 is provided on the conveyor belt 103.

[0047] When testing the ink thickness, the processed glass is placed with the ink side facing up in the positioning fixture 5. The electric roller 102 then rotates to drive the conveyor belt 103 to move, so that the conveyor belt 103 drives the positioning fixture 5 and the cover plate to be tested to be transported, and passes under the fixing frame 2 and the testing frame 3 to clean the ink on the surface of the cover plate and test its thickness.

[0048] The device for detecting the thickness of the cover plate ink on-line provided in Example 1 is further optimized, specifically, as follows Figure 1-5As shown, the fixing frame 2 is arranged in an inverted U-shaped structure, with two fixed blocks 201 connected to the bottom of the fixing frame 2, a movable groove 202 is opened inside the fixed block 201, both ends of the cleaning roller 206 are rotatably connected to the mounting blocks 205, the movable groove 202 is slidably connected to the movable block 204, the top of the mounting block 205 extends into the movable groove 202 and is connected to the lower surface of the movable block 204, and multiple movable springs 203 are connected between the movable block 204 and the movable groove 202.

[0049] When the positioning fixture 5 brings the cover plate to the bottom of the fixed frame 2, the cover plate contacts the cleaning roller 206. At this time, the cleaning roller 206 rotates to clean the dust and impurities on the ink on the surface of the cover plate, thereby ensuring the accuracy of the subsequent detection of the ink thickness on the cover plate surface and avoiding the presence of dust and impurities affecting the detection accuracy. When cleaning inks or covers of different thicknesses, the movable spring 203 is extended and retracted to enable the movable block 204 to slide in the movable groove 202, thereby changing the height position of the mounting block 205 and the cleaning roller 206. At the same time, the elastic force generated by the movable spring 203 acts on the mounting block 205, so that the mounting block 205 with the pending cleaning roller 206 only relies on the cover plate on the positioning fixture 5, thereby ensuring the cleaning effect.

[0050] The device for detecting the thickness of the cover plate ink on-line provided in Example 1 is further optimized, specifically, as follows Figure 1-5 As shown, the detection frame 3 is arranged in an inverted U-shaped structure, a laser head 301 is installed at the bottom of the detection frame 3, a positioning sensor 302 is installed on the inner wall of one side of the detection frame 3, and the positioning sensor 302 is on the same horizontal line as the conveyor belt 103, and a display 303 is installed on the top of the detection frame 3.

[0051] When the positioning fixture 5 drives the sample to be transported to the bottom of the detection frame 3, when the positioning sensor 302 senses the sample on the positioning fixture 5, the laser head 301 and the positioning sensor 302 are started, and the laser head 301 performs a laser scan on the curved surface of the glass surface in the X and Y directions on the track. After scanning, the scan data is transmitted to the display 303, and the scanned outline is displayed on the display 303. Then, whether the ink thickness is qualified is determined according to the ink thickness range input in advance on the display 303.

[0052] The online detection cover plate ink thickness device provided in Example 3 is further optimized, specifically, as follows Figure 1-5As shown, the rotating manipulator module includes: a rotating module 4, a rotating rod 401, a telescopic rod 402 and a suction cup 403. A rotating module 4 is provided on one side of the workbench 1. The top of the rotating module 4 is connected to the rotating rod 401, and the rotating rod 401 is located above the conveyor belt 103. The telescopic rod 402 is installed at the bottom of the rotating rod 401, and the bottom of the telescopic rod 402 is connected to the suction cup 403. A plurality of suction nozzles 404 are provided at the bottom of the suction cup 403. An air compressor 405 is installed on the top of the rotating rod 401, and the bottom of the air compressor 405 is connected to a conduit 406, and the conduit 406 is connected to the plurality of suction nozzles 404.

[0053] If the ink thickness is within the scanned range, it will be transported to the next workstation via the conveyor belt 103. If it exceeds the thickness range, the computer program will activate the rotating robot module. After the glass is completely moved to the appropriate position, the suction cup 403 extends downward to suck the glass. The robot then rotates and places the glass on the defective product tray to intercept it. At the same time, the equipment will alarm and notify the process and quality personnel to confirm and handle the problem on site.

[0054] When the positioning fixture 5 with the unqualified sample moves to the bottom of the suction cup 403, the suction cup 403 is driven down to the sample surface by the telescopic rod 402, and multiple suction nozzles 404 are brought into contact with the sample surface. Then, the air inside the suction nozzle 404 is extracted through the air compressor 405 and the conduit 406, so that the air pressure inside the suction nozzle 404 drops, generating suction to adsorb the unqualified sample. Then, the telescopic rod 402 retracts, and the unqualified sample is placed on the defective product tray through the rotating module 4.

[0055] The use process of the automatic column passing device provided by the utility model is as follows:

[0056] When testing the ink thickness, the processed glass is placed with the ink side facing up in the positioning fixture 5. The electric roller 102 then rotates to drive the conveyor belt 103 to move, so that the conveyor belt 103 drives the positioning fixture 5 and the cover plate to be tested to be transported, and thereby pass under the fixing frame 2 and the detection frame 3.

[0057] When the positioning fixture 5 brings the cover plate to the bottom of the fixed frame 2, the cover plate contacts the cleaning roller 206. At this time, the cleaning roller 206 rotates to clean the dust and impurities on the ink on the surface of the cover plate, thereby ensuring the accuracy of the subsequent detection of the ink thickness on the cover plate surface and avoiding the presence of dust and impurities affecting the detection accuracy. When cleaning inks or covers of different thicknesses, the movable spring 203 is extended and retracted to enable the movable block 204 to slide in the movable groove 202, thereby changing the height position of the mounting block 205 and the cleaning roller 206. At the same time, the elastic force generated by the movable spring 203 acts on the mounting block 205, so that the mounting block 205 with the pending cleaning roller 206 only relies on the cover plate on the positioning fixture 5, thereby ensuring the cleaning effect.

[0058] When the positioning fixture 5 drives the sample to be transported to the bottom of the detection frame 3, when the positioning sensor 302 senses the sample on the positioning fixture 5, the laser head 301 and the positioning sensor 302 are started, and the laser head 301 performs a laser scan on the curved surface of the glass surface in the X and Y directions on the track. After scanning, the scan data is transmitted to the display 303, and the scanned outline is displayed on the display 303. Then, whether the ink thickness is qualified is determined according to the ink thickness range input in advance on the display 303.

[0059] If the scanned ink thickness is qualified, it will be transported to the next workstation via the conveyor belt 103. When the positioning fixture 5 with the unqualified sample moves to the bottom of the suction cup 403, the suction cup 403 is driven down to the sample surface by the telescopic rod 402, and multiple suction nozzles 404 are brought into contact with the sample surface. Then, the air inside the suction nozzle 404 is extracted through the air compressor 405 and the conduit 406, so that the air pressure inside the suction nozzle 404 drops, generating suction to absorb the unqualified sample. Then, the telescopic rod 402 is retracted, and the unqualified sample is placed on the defective product tray through the rotating module 4.
