[0002] During the manufacturing process of LCD electronic products, semi-finished products and finished products must be continuously tested to eliminate defective products and send genuine products to the next process for processing. At the same time, the products leaving the factory must be inspected and re-inspected again.

[0003] In the relevant detection technology, the flexible circuit board of the LCD screen needs to be plugged into the flexible circuit board used for detection to perform screen display detection. The applicant has found that during the detection process, after the detection is completed, the operator is usually required to manually separate the two plugged flexible circuit boards, because the flexible circuit board itself is flexible and an LCD screen needs to be replaced every time it is detected. Therefore, in order to facilitate the replacement of the LCD screen, the flexible circuit board connected to it is usually exposed to the outside world. However, this results in that when the two plugged flexible circuit boards are separated, if the flexible circuit board of the LCD screen is not pressed, the flexible circuit board will drive the LCD screen to leave the detection station together, causing the connection between the flexible circuit board and the LCD screen to become loose, and even involving the LCD screen causing the LCD screen to bump against the detection station.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the meaning of "and / or" appearing in the full text includes three parallel schemes. Taking "A and / or B" as an example, it includes scheme A, or scheme B, or a scheme that satisfies both A and B. In addition, the technical solutions between the various embodiments can be combined with each other, but it must be based on the ability of ordinary technicians in this field to implement. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present utility model.

[0038] The utility model provides an LCD quality inspection jig, such as Figures 1 to 4As shown, the LCD quality inspection fixture includes a base 10, a detection component and a first fixed card 40. The base 10 is provided with a detection station 20, and the detection station 20 is used to place an LCD screen 60 and a flexible circuit board 61 electrically connected to the LCD screen 60; the detection component is arranged on the base 10, and the detection component includes a detection switch 50, a detection main board and a drive main board. The detection main board is electrically connected to the detection switch 50, and the drive main board is plugged into the detection main board and the flexible circuit board 61; the first fixed card 40 is arranged at the detection station 20, and the first fixed card 40 is provided with a fixed notch 40a. The first fixed card 40 and the detection station 20 enclose a placement space for placing the flexible circuit board 61, and the fixed notch 40a is connected to the placement space.

[0039] In this embodiment, the LCD screen 60 to be inspected is placed on the inspection station 20, the plug of the driving main board is inserted into the socket of the flexible circuit board 61 of the LCD screen 60, and then the inspection switch 50 is pressed to perform screen display inspection. After the inspection is completed, the connection can be directly disassembled to perform the next screen inspection. In this process, because the first fixing card 40 can fix the flexible circuit board 61 of the LCD screen 60, there is no need to fix the flexible circuit board 61 at other positions, thereby preventing excessive pressing from causing mechanical damage to the flexible circuit board 61; at the same time, because the first fixing card 40 and the inspection station 20 are enclosed to form a placement space for the flexible circuit board 61 of the LCD screen 60, and the first fixing card 40 has a fixed notch 40a, the flexible circuit board 61 can be directly placed under the first fixing card 40 through the placement space, which is also convenient for directly extracting the LCD screen 60 after the inspection is completed. Through this LCD quality inspection jig, there is no need to use external force to press the flexible circuit board 61 of the LCD screen 60, which effectively prevents damage to the LCD screen 60 due to forgetting to press, simplifies the disassembly process, and improves the inspection efficiency.

[0040] The base 10 is mainly used to install the workpieces required for testing the LCD screen 60. There is no limitation on its basic properties such as shape, geometric dimensions and materials. A testing station 20 is provided on the base 10. The testing station 20 is used to place the LCD screen 60 and a flexible circuit board 61 electrically connected to the LCD screen 60. There is no limitation on the basic properties such as shape, geometric dimensions and materials of the testing station 20. It can be understood that the base 10 not only has the testing station 20, but also has other testing workpieces that cooperate with the testing station 20. Each testing station 20 and components, etc. should be reasonably positioned for ease of use. The specific design can be adaptively adjusted according to actual use, which is not limited here.

[0041] The detection component is mainly used to detect various display qualities of the LCD screen 60. The detection component includes a detection switch 50, a detection main board and a drive main board. The detection main board is provided with a corresponding detection program for detecting the LCD screen 60, including but not limited to display effects such as brightness, color contrast, etc. The drive main board is used to electrically connect the flexible circuit board 61 of the LCD screen 60 and the detection main board, and plays a transmission role. A separate drive main board that is detachably connected to the detection main board can mainly play a role in sharing damage. However, when the detection main board is accidentally burned, it can be replaced without replacing all of it. The detection switch 50 plays a control function, which is used to turn on, off and switch the detection mode. It can be understood that there is no specific limitation on the position design of the detection component, and it only needs to meet the convenience of use and safety, etc.

[0042] The first fixing card 40 can be made of various non-conductive materials to prevent unnecessary losses caused by conductive problems due to some unexpected situations during detection. The first fixing card 40 is arranged at the socket of the flexible circuit board 61, and can be connected to the empty space by means of snap connection or screw connection. A fixing notch 40a is provided on one side of the first fixing card 40. The fixing notch 40a is mainly convenient for inserting a part of the interface of the end of the flexible circuit board 61, while exposing the socket of the flexible circuit board 61. It can be understood that in order to facilitate the insertion of the flexible circuit board 61, a placement space for the flexible circuit board 61 is formed between the first fixing card 40 and the detection station 20. The placement space can be a support plate provided at both ends of the first fixing card 40 to form a placement space between it and the detection station 20, or a groove is provided at the part of the detection station 20 where the flexible circuit board 61 is placed, and a placement space is formed between the groove and the first fixing card 40. The specific design can be based on actual needs and is not limited. When the detection process is completed, the flexible circuit board 61 needs to be disassembled from the driving main board. Because the first fixing card 40 presses the peripheral part of the flexible circuit board 61 with an interface, there is no need to add another pressing work to prevent the flexible circuit board 61 from driving the LCD screen 60 when the connection is released, thereby avoiding unexpected situations and avoiding unnecessary losses caused by operational errors. Of course, because the first fixing card 40 is provided with a fixed notch 40a, the first fixing card 40 does not completely press the interface of the flexible circuit board 61, resulting in a part of the flexible circuit board 61 still detaching from the detection station 20 when released, but it is not enough to drive the LCD screen 60.

[0043] In one embodiment of the present utility model, Figure 1 As shown, the detection station 20 is provided with a positioning slot, which is arranged on a side of the detection station 20 facing away from the base 10 , and the first fixing member 40 and the positioning slot are enclosed to form a placement space.

[0044] In this embodiment, the detection station 20 is provided with a positioning slot for placing the flexible circuit board 61. The positioning slot is provided on the side of the detection station 20 facing away from the base 10. On the one hand, the positioning slot can directly align the interface of the flexible circuit board 61 to the socket of the driving main board, and manual positioning is no longer required; on the other hand, it can form a placement space with the first fixed card 40, and directly place the flexible circuit board 61 in the positioning slot so that its interface passes through the fixed notch 40a and enters the placement space. It can be understood that there is no limitation on the depth and width of the positioning slot, and it can be designed according to the specific model of the LCD screen 60 to be detected to meet the use requirements.

[0045] In one embodiment of the present utility model, Figure 1 and Figure 2 As shown, the LCD quality inspection jig is provided with a pressing mechanism 30, the pressing mechanism 30 includes a pressing bracket 301 and a pressing portion 302, the detection main board and the driving main board are arranged in the pressing portion 302, and at least part of the driving main board is exposed to the outside;

[0046] The pressing bracket 301 is disposed at one end of the base 10 away from the detection station 20, and the pressing portion 302 is connected to the pressing bracket 301;

[0047] The LCD quality inspection jig has a detection state. In the detection state, the pressing portion 302 abuts against the detection station 20 to allow the detection mainboard to be plugged into the flexible circuit board 61 .

[0048] In this embodiment, the LCD quality inspection jig is provided with a pressing mechanism 30, which includes a pressing bracket 301 and a pressing portion 302. The pressing bracket 301 is arranged on a side of the base 10 away from the detection station 20, and the pressing portion 302 is arranged on the pressing bracket 301. The detection main board and the driving main board are arranged in the pressing portion 302, mainly for the purpose of structural protection; the pressing portion 302 can move along the pressing bracket in the vertical direction, because the LCD quality inspection jig has a detection state. In the detection state, the pressing portion 302 abuts against the detection station 20 to enable the detection main board to be plugged into the flexible circuit board 61. It is understandable that the pressing part 302 can be moved along the pressing bracket 301 in the vertical direction by setting a moving part such as a pulley on the pressing part 302, and opening a moving guide groove or guide rail on the pressing bracket 301, that is, the pulley can be used to move up and down in the moving guide groove or the moving guide rail, and the pressing part 302 can be moved to abut against the detection station 20, so as to realize the electrical connection between the socket of the driving mainboard and the interface of the flexible circuit, and enter the detection state; in another embodiment, the corresponding connecting block can also be designed to realize the movement of the pressing part 302 along the pressing bracket in the vertical direction by a hinged manner, and the specific explanation will be described in detail later. It is understandable that because the pressing part 302 will abut against the detection station 20 in the detection state, a limiting structure can be designed to limit the moving stroke of the pressing part 302, and a limiting structure can also be not designed to limit the stroke, because the detection work can also play a limiting role to prevent the pressing part 302 from falling further after abutting against the detection station 20. It can be understood that the up and down movement can facilitate the connection and contact of the corresponding interfaces and sockets. When the detection station 20 and the pressing part 302 are pressurized, there are opposing forces to connect the two. When the pressing part 302 moves upward, due to the action of the first fixing card, the flexible circuit board 61 will definitely not be moved by the driving circuit board.

[0049] In one embodiment of the present utility model, Figure 1 and Figure 2 As shown, the pressing mechanism 30 further includes a pressing handle 303 and a connecting assembly, and the connecting assembly includes a hinge block 304 and a connecting rod 305;

[0050] The pressing handle 303 is hinged to the pressing bracket 301 and the hinge block 304 respectively, and two ends of the connecting rod 305 are connected to the hinge block 304 and the pressing portion 302 respectively.

[0051] In this embodiment, the pressing mechanism 30 also includes a pressing handle 303 and a connecting component, the connecting component includes a hinge block 304 and a connecting rod 305, one end of the pressing handle 303 is respectively connected to the pressing bracket 301 and the hinge block 304 in the vertical direction, when an upward force is applied to the pressing handle 303, the pressing handle 303 will move upward around the pressing bracket 301, at this time, the hinge block 304 moves upward due to the connection with the pressing handle 303, thereby driving the connecting rod 305 to move upward, so that the pressing part 302 can move upward, and the connection between the interface and the socket can be released; when no external force is applied to the pressing handle 303, under the influence of gravity, the pressing part 302 will naturally abut the detection station 20, thereby realizing the connection between the interface and the socket. It can be understood that the pressing handle 303 is mainly used to facilitate the application of force to move the pressing part 302 up and down, and there is no limitation on the specific design of the pressing handle 303. Similarly, the hinge block 304 and the connecting rod 305 mainly play a connecting role, and there is no limitation on the specific design, as long as the needs are met.

[0052] In one embodiment of the present utility model, Figure 4 As shown, the LCD quality inspection jig further includes a second fixing card 41, the second fixing card 41 is provided with a fixing groove 41a, and the second fixing card 41 is arranged on a side of the pressing portion 302 facing the base 10;

[0053] In the detection state, the second fixing member 41 is connected to the first fixing member 40 so that the fixing groove 41 a is aligned with the fixing notch 40 a.

[0054] In this embodiment, the LCD quality inspection jig also includes a second fixing card 41, which is provided with a fixing groove 41a. The second fixing card 41 is provided on the side of the pressing portion 302 facing the base 10. The second fixing card 41 can mainly fix the drive board at the socket exposed to the outside world to prevent the drive board from being pulled by the interaction of forces so that the connection between the drive board and the detection main board becomes loose, causing problems such as detection interruption. It can be understood that the second fixing card 41 is formed of a non-conductive material to prevent the occurrence of conductive problems; because during the use of the LCD quality inspection jig, the detection main board and the drive main board do not need to be replaced unless there is force majeure, because the second fixing card 41 is set to a thin sheet shape to achieve the fixation of the drive main board.

[0055] In one embodiment of the present utility model, Figure 1 and Figure 2 As shown, the pressing bracket 301 also includes a limiting ring 306 , and the connecting rod 305 is inserted into the limiting ring 306 .

[0056] In this embodiment, the pressing bracket 301 also includes a limiting collar 306, and the connecting rod is inserted into the limiting collar 306. The limiting collar 306 mainly prevents the connecting rod 305 from angularly offset when moving up and down, so that the driving electric board cannot align with the flexible circuit board 61, thereby causing difficulty in connecting and contacting the flexible circuit board 61 and the driving electric board. It can be understood that the limiting collar 306 can be integrally formed and the pressing bracket 301 can also be detachably connected. The specific design is not limited, and the geometric size of the limiting collar 306 is not limited. It only needs to realize that the connecting rod 305 can move up and down in the limiting collar 306.

[0057] In one embodiment of the present utility model, Figure 1 and Figure 2 As shown, the pressing mechanism 30 further includes a pressing limit column 307, and the pressing limit column 307 is disposed on the base 10;

[0058] In the detection state, the side of the pressing portion 302 facing the base 10 abuts against the pressing limit column 307 .

[0059] In this embodiment, the pressing mechanism 30 also includes two pressing limit posts 307, which are arranged at intervals. The pressing limit posts 307 are arranged at the base 10 where the pressing part 302 can be abutted. When the pressing part 302 abuts the detection station 20, although it can prevent the pressing part 302 from moving further downward, when the contact area is limited, the abutment may be unstable. The pressing limit posts 307 can play a supporting and limiting role when the two abut. It can be understood that there is no specific requirement for the number, installation position and shape of the pressing limit posts 307, as long as they can meet the needs.

[0060] In one embodiment of the present utility model, Figure 1 and Figure 2 As shown, the pressing mechanism 30 also includes a limiting guide rod 308, and the pressing portion 302 is provided with a limiting hole; the two ends of the limiting guide rod 308 are respectively connected to the pressing bracket 301 and the base 10, and at least part of the limiting guide rod 308 is inserted into the guide hole.

[0061] In this embodiment, the pressing mechanism 30 also includes a limiting guide rod 308. The pressing portion 302 is provided with a limiting hole through which the limiting guide rod 308 can pass. The two ends of the limiting guide rod 308 are respectively connected to the pressing bracket 301 and the base 10. When the pressing portion 302 moves up and down, the limiting guide rod 308 can limit the moving direction of the pressing portion 302 to prevent the pressing portion 302 from being displaced and skewed, so that the driving electric board cannot be aligned with the flexible circuit board 61, thereby making it difficult to connect and contact the flexible circuit board 61 and the driving electric board.

[0062] In one embodiment of the present invention, the LCD quality inspection fixture is provided with a battery module and a DC module, the battery module includes a mobile battery, and the DC module includes a power plug; the mobile battery is arranged on the pressing portion 302 and is electrically connected to the detection mainboard, and the power plug is arranged on the base 10 and is electrically connected to the detection mainboard.

[0063] In this embodiment, the inventors have provided a battery module and a DC module based on practical considerations, taking into account that relevant quality inspectors may conduct inspections in non-fixed locations, such as on business trips, etc. The mobile battery of the battery module is located at the position of the pressing portion 302 and is electrically connected to the inspection mainboard, and the power supply plug of the DC module is located at one side of the base 10 and is electrically connected to the inspection mainboard. The mobile battery is located at the pressing portion 302 to fully utilize the space of the pressing portion 302, and a corresponding battery accommodating slot is provided in the pressing portion 302. It is understandable that the design positions of the battery module and the DC module are not limited, and can be satisfied as long as the requirements are met.

[0064] In one embodiment of the present utility model, Figure 1 As shown, the detection switch 50 includes a switch key 501 and a function switching key 502 . The switch key 501 and the function switching key 502 are arranged on the base 10 at intervals along the length direction of the base 10 and are electrically connected to the detection main board.

[0065] In this embodiment, the detection switch 50 includes a switch key 501 and two function switching keys 502. The switch key 501 and the function switching keys 502 are arranged on the base 10 at intervals along the length direction of the base 10 and are electrically connected to the detection mainboard. By designing multiple switches, multiple display adjustments of the LCD screen 60 can be realized mainly through one detection mainboard, thereby enhancing practicality.

[0066] The above are only preferred embodiments of the present invention, and do not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
