Description

Technical Field

[0001] This utility model relates to the field of liquid crystal panel measurement technology, and in particular to a liquid crystal panel size measuring device. Background Technology

[0002] In the production and processing of LCD panels, in order to ensure production quality, it is necessary to measure the thickness of the LCD panels. Currently, micrometers are usually used for this operation. However, some existing micrometers have relatively smooth surfaces, which may cause them to slip and fall during the measurement process, resulting in wear on the surface of the micrometer and thus affecting the accuracy of the LCD panel thickness measurement.

[0003] Existing patent CN217844957U discloses a thickness measuring device for LCD panel production. In the event of a drop, the inner mounting strap prevents the micrometer from falling to the ground. By combining the clamp, the micrometer rod, and the anti-drop mechanism, the device can protect the micrometer from falling during measurement without affecting the thickness measurement of the LCD panel workpiece. This reduces the chance of the operator's hand slipping and the micrometer falling, causing surface wear and affecting measurement accuracy, and improves the safety of LCD panel measurement.

[0004] However, in the aforementioned prior art, it is impossible to measure the size of the LCD panel, and it is impossible to ensure whether the size of the produced LCD panel meets the standard, which is very inconvenient. Utility Model Content

[0022] The LCD panel 109 is mounted on the support base 101. The bracket 102 is fixedly connected to the support base 101 and located above the support base 101. The rotation adjustment unit is mounted on the bracket 102. The cylinder 103 is mounted on the rotation adjustment unit and its output end is fixedly connected to the turntable 104.

The first industrial camera 107 and the second industrial camera 108 are fixedly connected to their respective abutment plates 105 and located on one side of their respective abutment plates 105. The heights of the first industrial camera 107 and the second industrial camera 108 are the same as those of the pressure sensor 106, thus avoiding errors caused by being too low or too high. After the LCD panel 109 is placed, the cylinder 103 is activated, driving the turntable 104 to move downwards. Then, the bidirectional drive unit is activated, driving the two abutment plates 105 to move relative to each other, clamping and fixing the LCD panel 109. At the same time, the pressure sensor 106 detects the clamping pressure to prevent excessive clamping force from damaging the LCD panel 109. Then, the first industrial camera 107... 07 and the second industrial camera 108 simultaneously take pictures from both sides of the liquid crystal panel 19. Using the bottom surface reflection principle, the four sides of the workpiece are recorded, thereby measuring and calculating the length of the workpiece. Then, the cylinder 103 drives the turntable 104 to move upward, and the rotation adjustment unit drives the turntable 104 to rotate, thereby switching the clamping position and measuring the width of the liquid crystal panel 109. Thus, the length and width of the liquid crystal panel 109 can be measured to obtain accurate dimensions and ensure the pass rate of the production dimensions of the liquid crystal panel 109. In addition, a controller (not shown in the figure) is installed inside the support base 101 of this application. The cylinder 103, the first industrial camera 107, the second industrial camera 108, the first motor 110 and the second motor 112 of this application are all electrically connected to the controller. Thus, the operator can connect to the controller through the host system and send control commands through the controller to control all the equipment and realize the operation of the equipment.

[0023] Secondly, the first motor 110 is fixedly connected to the bracket 102 and located below the bracket 102. One end of the drive shaft 111 is fixedly connected to the output end of the first motor 110, and the other end of the drive shaft 111 is fixedly connected to the turntable 104.

[0024] Meanwhile, the second motor 112 is fixedly connected to the turntable 104 and located on the outer wall of the turntable 104. The turntable 104 has a slot 116. One end of the first threaded rod 113 is fixedly connected to the output end of the second motor 112. The other end of the first threaded rod 113 passes through the turntable 104 and is fixedly connected to one end of the connecting shaft 115. The connecting shaft 115 is located inside the slot 116. One end of the second threaded rod 114 is rotatably connected to the inner wall of the slot 116. The other end of the second threaded rod 114 is fixedly connected to the other end of the connecting shaft 115. The first threaded rod 113 and the second threaded rod 114 are symmetrically distributed inside the slot 116. Both of the abutment plates 105 have threaded holes 117. The first threaded rod 113 and the second threaded rod 114 are respectively adapted to the corresponding threaded holes 117. When the second motor 112 starts, it drives the first threaded rod 113 to rotate. Through the connection of the connecting shaft 115, it drives the second threaded rod 114 to rotate. Through the cooperation with the threaded hole 117, it drives the two abutment plates 105 to move relative to each other.

[0025] When using this invention to measure the dimensions of the LCD panel 109, after the LCD panel 109 is placed, the cylinder 103 is activated, driving the turntable 104 to move downwards. Then, the second motor 112 is activated, driving the first threaded rod 113 to rotate. Through the connection of the connecting shaft 115, the second threaded rod 114 is driven to rotate. Through the cooperation with the threaded hole 117, the two abutment plates 105 move relative to each other, clamping and fixing the LCD panel 109. At the same time, the pressure sensor 106 detects the clamping pressure to prevent excessive clamping force from damaging the LCD panel 109. Then, the first working... Industrial camera 107 and the second industrial camera 108 simultaneously take pictures from both sides of the LCD panel 109. Utilizing the bottom surface reflection principle, they record the four sides of the workpiece to be measured, thereby calculating the workpiece length. Then, cylinder 103 drives the turntable 104 to move upward, and the first motor 110 starts, driving the drive shaft 111 to rotate, causing the turntable 104 to rotate and thus switching the clamping position to measure the width of the LCD panel 109. Through the above structural setup, the length and width of the LCD panel 109 can be measured to obtain accurate dimensions, ensuring the pass rate of the LCD panel 109's production dimensions.

[0030] When using this invention to reinforce the turntable 104, the turntable 104 rotates, and through the connection of the telescopic rod 201, it drives the slider 202 to slide in the annular groove 203, thereby ensuring rotational stability and reducing shaking. At the same time, when the turntable 104 moves up and down, the telescopic rod 201 extends and retracts accordingly, thereby reinforcing and supporting the rotation of the turntable 104 and preventing shaking.
