Description

Technical Field

[0001] This utility model relates to the field of LCM appearance inspection technology, and in particular to an LCM bonding appearance inspection device. Background Technology

[0002] LCM (LCD Module) refers to an LCD display module or liquid crystal module, which is an assembly that combines liquid crystal display devices, connectors, peripheral circuits such as control and drive, PCB circuit boards, backlights, structural components, etc. The LCM bonding appearance inspection device is a device used to inspect the bonding appearance quality of liquid crystal display modules, and can detect a variety of appearance defects in the LCM production process.

[0003] Patent publication number CN217717933U discloses an LCM adhesion defect detection and identification device, including a base, a concave frame fixedly connected to the top of the base, a housing fixedly connected to the top of the concave frame, and a servo motor disposed within the housing cavity. This invention uses a servo motor to drive a rotating rod, which in turn drives a gear, which in turn drives a toothed plate to move back and forth. The toothed plate, through a connecting column, moves the detector body back and forth, adjusting the detection position and improving the accuracy of the detection results. The inclusion of springs, limiting plates, anti-slip pads, a moving rod, and a moving block facilitates the limiting of the display, preventing the display from becoming loose. This structure provides the advantage of adjustable detection position, solving the problem of existing detection and identification devices lacking this feature, thus better meeting user needs.

[0004] Traditional testing devices only focus on the appearance of the LCM front bonding area, while ignoring the bonding condition of the LCM side assembly. The LCM side assembly is of great significance to the overall structural integrity and stability of the product. Poor bonding may lead to poor sealing and moisture intrusion during subsequent use, resulting in serious consequences such as display failure and shortened product lifespan.

[0005] Even though some equipment attempts to inspect different sides of the LCM, the operation process is extremely cumbersome. After one side is inspected, the LCM needs to be manually disassembled and then re-adjusted and clamped in order to inspect the other side. This process not only consumes a lot of manpower, material resources and time, but also introduces additional error risks due to frequent loading and unloading operations. Utility Model Content

[0006] The purpose of this invention is to provide an LCM (Liquid Clay) fit appearance inspection device that can efficiently and reliably detect the side fit of LCMs, improve the integrity of the inspection, and effectively solve the problems in the prior art.

[0031] The following detailed description, in conjunction with the accompanying drawings, outlines some embodiments of the present invention. Unless otherwise specified, the following embodiments and features can be combined with each other.

[0032] Please refer to Figures 1-8 This utility model provides an LCM bonding appearance inspection device, including a housing 1. A fixing frame 7 is provided in the middle part of the housing 1. A supporting mechanism 8 for supporting the LCM body 9 is provided in the middle of the fixing frame 7. A fixing mechanism 2 for fixing the LCM body 9 is provided at the upper end of the fixing frame 7. A robotic arm 3 for loading and unloading and a mounting frame 4 are respectively provided inside the housing 1 and on both sides of the fixing frame 7. An inspection instrument 5 for detecting the bonding degree of the LCM body 9 is installed on the mounting frame 4.

[0033] The controller 6 is installed on the front of the housing 1, and the detector 5 is located directly above the center of the LCM body 9.

[0034] In this application, the controller 6 is electrically connected to the electrical equipment in the device and is used to control the start and stop of each electrical device. The robotic arm 3 can place the LCM body 9 into the support mechanism 8 and remove the LCM body 9 from the support mechanism 8. The fixing mechanism 2 can fix and flip the LCM body 9. In conjunction with the detector 5, multi-faceted inspection of the LCM body 9 can be realized. The detector 5 can detect the fit of the side of the LCM body 9. The system acquires images of the object surface through an optical lens, and then uses image processing algorithms and pattern recognition technology to compare and analyze the acquired images with pre-set standard images or templates. If there are areas in the image that do not conform to the standard, such as differences in shape, color, texture, etc., the system will determine that the area is a defect and record and analyze the type, location, size and other information of the defect.

[0035] The fixing mechanism 2 includes a first driving component 21 and a second driving component 23. The first driving component 21 and the second driving component 23 are respectively disposed on both sides of the upper end of the fixing frame 7. Both the first driving component 21 and the second driving component 23 include a fixing seat 211. The fixing seat 211 is fixedly installed on the fixing frame 7. A clamping cylinder 212 is fixedly installed on the fixing seat 211. A movable plate 213 is fixedly connected to the output end of the clamping cylinder 212. The bottom of the movable plate 213 is slidably connected to the fixing seat 211.

[0036] In this application, the first drive assembly 21 and the second drive assembly 23 have the same structure and are both used to drive the clamping frame 225 to move, thereby clamping or releasing the LCM body 9. Specifically, by activating the clamping cylinder 212, the movable plate 213 is moved. The movable plate 213 slides along the fixed base 211, thereby driving the clamping frame 225 to move synchronously. The strokes of the clamping cylinders 212 on both sides are the same. With this setting, the LCM body 9 can be quickly fixed in the middle position, which is convenient for the detection instrument 5 to detect.

[0037] A flipping assembly 22 is provided on the movable plate 213. The flipping assembly 22 includes a clamping frame 225. An anti-slip pad 226 is provided on the clamping frame 225. The clamping frame 225 abuts against both sides of the LCM body 9. Several connecting rods 224 are fixedly connected to one side of the clamping frame 225. One end of the connecting rod 224 is rotatably installed in the movable plate 213 through a bearing 227. A motor 221 is fixedly installed on one side of the movable plate 213. A worm gear 222 is fixedly connected to the output end of the motor 221. A worm wheel 223 is meshed with one side of the worm gear 222. The worm wheel 223 is fixedly installed at one end of the connecting rod 224.

[0038] In this application, the flipping assembly 22 flips the LCM body 9 by rotating the clamping frame 225, changing the surface to be inspected. Specifically, after the first surface is inspected, the motor 221 is started to drive the worm gear 222 and worm wheel 223 to rotate. The worm wheel 223 drives several connecting rods 224 and the clamping frame 225 to rotate, thereby causing the LCM body 9 to rotate synchronously, so that the next surface faces the direction of the detector 5. With this setting, continuous inspection can be achieved without disassembling the LCM body 9 to change its position and then fixing it, thereby improving the inspection efficiency.

[0039] The support mechanism 8 includes a support frame 85 and a base plate 81. The base plate 81 is fixedly installed inside the fixed frame 7. A slide rod 82 and a guide rod 84 are fixedly installed at the bottom of the support frame 85. A spring 83 is sleeved on the slide rod 82. The bottom of the slide rod 82 and the guide rod 84 slide through the base plate 81. The two ends of the spring 83 are fixedly connected to the support frame 85 and the base plate 81, respectively.

[0040] In specific configuration, the support mechanism 8 is used to support the LCM body 9 to prevent it from falling and being damaged accidentally. During operation, the bottom of the LCM body 9 is inserted into the support frame 85 by the robotic arm 3, and then the LCM body 9 is fixed by the first drive assembly 21 and the second drive assembly 23. During the flipping of the LCM body 9, the LCM body 9 presses the support frame 85 downward, the spring 83 contracts, and the slide rod 82 and guide rod 84 slide on the base plate 81. After the LCM body 9 returns to its upright position, the support frame 85 moves upward under the elastic force of the spring 83, always in contact with the bottom of the LCM body 9, which can play a good supporting and protective role for the LCM body 9.

[0041] In summary, the working principle of the LCM bonding appearance inspection device according to this utility model embodiment is as follows:

[0042] First, the bottom of the LCM body 9 is inserted into the support frame 85 using the robotic arm 3. Then, the clamping cylinder 212 is activated, moving the movable plate 213 and causing the two side clamping frames 225 to move closer to the center until the LCM body 9 is fixed in the middle position. Afterward, the robotic arm 3 moves out, and the detector 5 acquires an image of the object's surface through an optical lens. Then, using image processing algorithms and pattern recognition technology, the acquired image is compared and analyzed with a pre-set standard image or template. If there are areas in the image that do not conform to the standard, such as shape, color, or texture, etc. If there is a difference in the surface, the system will determine that the area is a defect and record and analyze information such as the type, location, and size of the defect. After one surface is inspected, the motor 221 is started to drive the worm gear 222 and worm wheel 223 to rotate. The worm wheel 223 drives the clamping frame 225 to rotate, thereby causing the LCM body 9 to rotate. When rotating to the next surface, it stops and the inspection instrument 5 inspects the surface. During the inspection of the LCM body 9, the support frame 85 supports the LCM body 9 to prevent the LCM body 9 from falling and being damaged, thus improving the reliability of the inspection.

[0043] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
