[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1: See Figure 1 - Figure 5 An easily adjustable LCD module inspection camera includes a transplanting platform body 1 and a gantry frame 2 mounted above the transplanting platform body 1. Vertical linear motors 3 are symmetrically arranged on the inner side of the gantry frame 2. A frame 4, slidably mounted on the vertical linear motors 3 and connected to the gantry frame 2, is mounted on the rear end face of the frame 4. Multiple horizontal linear motors 7 are evenly arranged on the rear end face of the frame 4. A mounting plate 5, slidably mounted on the horizontal linear motors 7 and connected to the frame 4, is mounted on the bottom surface of the mounting plate 5. The vertical linear motors 3 facilitate the up-and-down movement of the inspection camera body 8, thereby adjusting its vertical position. The individual horizontal linear motors 7 allow for individual horizontal adjustment of the inspection camera body 8. This allows the number of inspection camera bodies 8 to be controlled according to the size of the LCD module, satisfying the inspection needs of LCD modules of different sizes.

[0022] Example 2: A slider 13 is provided on one side of the frame 4. The gantry 2 has a groove 6 that cooperates with the slider 13. A sealing cavity 12 is provided inside the slider 13. An oiling component is provided inside the sealing cavity 12. By using the oiling component, lubricating oil can be automatically added between the slider 13 and the groove 6 to avoid excessive friction and wear between the slider 13 and the groove 6. This helps to protect the slider 13 and improve its service life. At the same time, it prevents the slider 13 from making noise due to lack of lubricating oil and keeps the detection environment quiet.

[0023] In this utility model, the oil filling assembly includes a piston 15 slidably disposed in the sealing cavity 12, a movable rod 16 disposed on the top surface of the piston 15, and a return spring 10 sleeved on the outer wall of the movable rod 16 between the piston 15 and the sealing cavity 12. An oil cavity 9 is opened in the frame 4 near the slider 13. The oil cavity 9 is connected to the sealing cavity 12 through an oil inlet hole, and a one-way liquid inlet valve 11 is installed in the oil inlet hole. A strip-shaped oil groove is opened at the bottom of the inner end face of the slider 13. The strip-shaped oil groove is connected to the sealing cavity 12 through an oil outlet hole, and a one-way liquid outlet valve 14 is installed in the oil outlet hole.

[0024] In this invention, one end of the return spring 10 is fixedly connected to the top of the sealing cavity 12, and the other end is fixedly connected to the top surface of the piston 15. After the return spring 10 is stretched and reset, it will drive the piston 15 to move upward, thereby drawing the lubricating oil in the oil cavity 9 into the sealing cavity 12, thus realizing the addition of lubricating oil.

[0025] In this invention, the bottom surface of the oil cavity 9 is inclined, and the part near the oil inlet is lower than the part far from the oil outlet, which facilitates the oil in the oil cavity 9 to gather at the oil inlet, thereby facilitating the complete discharge of the lubricating oil in the oil cavity 9; while an oil injection hole is provided on the top surface of the oil cavity 9, which facilitates the addition of lubricating oil into the oil cavity 9, and a one-way valve is provided in the oil injection hole to prevent lubricating oil from leaking from the oil injection hole.

[0026] In this invention, an observation window is provided on the front end face of the oil chamber, and glass is embedded in the observation window to facilitate observation of the oil usage in the oil chamber, so as to add oil in a timely manner.

[0027] Working Principle: In use, this invention first transfers the product from the previous process to the camera imaging position via the transfer platform body 1. Then, the position of the detection camera body 8 is adjusted according to the size of the LCD module. First, the vertical linear motor 3 is turned on, which drives the frame 4 to move up and down, thereby driving the mounting plate 5 and the horizontal linear motor 7 to move up and down, thus driving the detection camera body 8 to move up and down. The height of the detection camera body 8 is adjusted to a suitable position according to the size of the LCD module. Then, the horizontal linear motor 7 is turned on, which drives the mounting plate 5 to move horizontally, thereby driving the detection camera body 8 to move left and right. Multiple detection cameras 8 can be adjusted to take pictures of the LCD module according to its size. The operation is simple and convenient, improving the efficiency of taking pictures of the LCD module. The pictures taken by multiple detection cameras 8 are collected in the API software and processed by the API software. Finally, the LCD module that has been photographed is moved away by the transfer platform body 1, and the next LCD module is moved in.

[0028] When the slider 13 lacks lubricating oil, the longitudinal linear motor 3 drives the frame 4 to move upward, so that the frame 4 moves to the top. Then, the movable rod 16 contacts the top of the slide groove 6 and drives the movable rod 16 to slide into the sealing cavity 12, thereby pushing the piston 15 to move. The lubricating oil in the sealing cavity 12 is squeezed into the strip oil groove through the oil outlet. Finally, the lubricating oil enters between the slider 13 and the slide groove 6, which facilitates the lubrication of the slider 13 and avoids wear of the slider due to excessive friction, thus further improving the service life of the slider 13. When the slider 13 moves downward, the piston 15 is reset under the action of the return spring 10, and then the lubricating oil in the oil chamber 9 enters the sealing cavity 12.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
