[0002] LCD (Liquid Crystal Display) is a display device that uses the photoelectric effect of liquid crystal to display images. Liquid crystal is a substance between solid and liquid, which has fluidity and optical anisotropy. When an electric field is applied, the arrangement of liquid crystal molecules will change, thereby changing its optical properties. Different images can be displayed by controlling the arrangement of liquid crystal molecules.

[0003] LCD pin connection is the most common LCD connection method. LCDs usually have one or more rows of metal pins for connecting drive circuits.

[0036] Example 1

[0037] like Figure 1-Figure 5 As shown, this embodiment provides an LCD pin adhesive detection device, the LCD includes a body 110 and a metal pin 120, one end of the metal pin 120 is connected to the body 110, and the other end of the metal pin 120 extends outward, and the metal pin 120 is perpendicular to the plane where the body 110 is located. The LCD pin adhesive detection device includes:

[0038] A fixing table 200 for fixing the LCD;

[0039] A test board 300 for testing the continuity of a circuit, the test board 300 being arranged below the fixing table 200, and a connection block 310 for connecting the metal pins 120 being arranged on the surface of the test board 300;

[0040] When the LCD is placed on the fixing platform 200 , the connecting block 310 faces the inner side surface of the metal pin 120 .

[0041] It should be noted that the inner side of the metal pin 120 refers to the side of the extended end of the metal pin 120 close to the body 110 , and the outer side of the metal pin 120 refers to the side of the extended end of the metal pin 120 away from the body 110 .

[0042] When performing LCD pin adhesive testing, the LCD body 110 is placed on the fixing platform 200, and the metal pins 120 of the LCD extend out of the fixing platform 200 and are connected to the test board 300 below the fixing platform 200. The test board 300 is connected to the inner side of the metal pins 120 through the connecting block 310 to test the electrical performance of the metal pins 120.

[0043] The LCD is fixed by the fixing table 200, and the test board 300 is arranged under the fixing table 200, and the connection block 310 on the test board 300 is directly opposite to the inner side of the metal pin 120. The connection block 310 contacts the inner side of the metal pin 120 to detect the continuity of the inner side of the metal pin 120, thereby realizing the detection of the adhesive on the inner side of the LCD metal pin 120. The efficiency of the LCD pin adhesive detection can be effectively improved, and the adhesive on the inner side of the pin can be detected.

[0044] Specifically, the fixing platform 200 can fix the LCD by setting the LCD limiting groove 210 .

[0045] Specifically, the fixing platform 200 may also be provided with a clamp, and the frame of the LCD display may be clamped by the clamp to fix the LCD.

[0046] Specifically, a magnet may be disposed on the fixing platform 200 to fix the LCD display on the fixing platform 200 by magnetic attraction.

[0047] Specifically, a vacuum suction cup may be provided on the fixing platform 200 to fix the LCD display on the fixing platform 200 by suction.

[0048] In this embodiment, a positioning component 400 is further included. The positioning component 400 is arranged on the outer side of the metal pin 120. The metal pin 120 is located between the positioning component 400 and the test board 300. The positioning component 400 can move in a direction perpendicular to the test board 300.

[0049] Specifically, the positioning assembly 400 may be a spring-pushing structure. After the LCD is placed at a predetermined position, the spring pushes the metal pin 120 to contact the connecting block 310 .

[0050] More specifically, the positioning component 400 can also be a conductive bevel block, the bevel of which faces the metal pin 120 and the connecting block 310. When the LCD is fixed on the fixing platform 200, the metal pin 120 contacts the conductive bevel block, and the conductive bevel block causes the metal pin 120 to bend inward to a certain extent, so that the metal pin 120 can better contact the connecting block 310.

[0051] By setting a positioning component 400 on the outer side of the metal pin 120, the metal pin 120 is tightly fitted with the test board 300 through the positioning component 400, ensuring that the metal pin 120 is stably connected to the connecting block 310 on the test board 300, making the detection result of LCD pin adhesive more accurate.

[0052] In this embodiment, the positioning assembly 400 includes a plurality of ejector pins 410 and a pin insertion platform 420 . The ejector pins 410 are disposed on the pin insertion platform 420 . Each ejector pin 410 is perpendicular to the plane where the metal pin 120 is located and faces the connection block 310 .

[0053] Specifically, the ejector pins 410 correspond to the metal pins 120 one by one.

[0054] More specifically, the ejector pin 410 is inserted into the pin insertion platform 420 through a through hole on the pin insertion platform 420 .

[0055] More specifically, the ejector pin 410 is fixed on the pin insertion platform 420 by UV glue.

[0056] In this embodiment, the number of the connecting blocks 310 is equal to the number of the metal pins 120, the connecting blocks 310 are arranged along the length direction of the test board 300, the plane where the axis of the connecting block 310 is located is 2 mm higher than the end of the metal pin 120, and a plurality of the ejector pins 410 are arranged in the same plane, and the plane where the axis of the ejector pin 410 is located is 2 mm higher than the end of the metal pin 120.

[0057] Specifically, the end of the metal pin refers to the end of one end of the metal pin extending out of the body.

[0058] The connection block 310 and the ejector pin 410 are arranged 2 mm higher than the end of the metal pin 120 , so that the force arm for pushing the metal pin 120 is increased as much as possible, which can effectively reduce the force required for pushing the metal pin 120 .

[0059] In this embodiment, a testing machine for LCD function testing is also included, and the testing machine is connected to the test board 300 via a flat cable.

[0060] By connecting the test board 300 to the inspection machine, the pin function of the LCD or the function of the LCD can be inspected while inspecting the adhesive of the LCD pins, which can effectively expand the inspection range of the LCD, realize multiple function inspections in the same process, and improve the inspection efficiency of the LCD.

[0061] In this embodiment, the fixing platform 200 includes a limiting groove 210 , which is used to fix the LCD. The limiting groove 210 is provided at the edge of the fixing platform 200 , has a rectangular cross section, and has a gap between the limiting groove 210 and the body 110 .

[0062] By fixing the LCD to be tested with the limiting groove 210 set on the surface of the fixing platform 200, it can effectively improve the guarantee that the LCD will not move during testing, ensure the accuracy and reliability of LCD testing, and avoid the LCD moving during the testing process to avoid damage to the LCD pins or the body 110.

[0063] In this embodiment, the fixed platform 200 also includes a corner groove 220, which is arranged at the corner of the limiting groove 210, and the corner groove 220 is connected to the limiting groove 210. The cross-section of the corner groove 220 is circular. The fixed platform 200 also includes a taking groove 230, which is arranged at the edge of the limiting groove 210, and the taking groove 230 is connected to the limiting groove 210.

[0064] The surface of the LCD is generally a glass substrate, and the corners of the glass substrate are very likely to be damaged or chipped when they come into contact with other hard objects. When the LCD is fixed by the rectangular limiting groove 210 on the fixing table 200, the corners of the LCD are very likely to be damaged by contact with the fixing table 200, so a corner groove 220 is set at the corner of the limiting groove 210 to increase the space at the corner of the limiting groove 210. When the LCD is placed in the limiting groove 210, the corner of the LCD is in the corner groove 220, and it is not easy to contact with the fixing table 200, which can effectively prevent the LCD from being damaged by contact with the fixing table 200.
