There are many steps in the operation process, which is not convenient for quickly fixing the display panel bare chip. For this reason, a detection device for liquid crystal display panel bare chip production is proposed. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. The embodiments described below with reference to the drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0025] The following describes an embodiment of the present invention based on its overall structure.

[0026] A detection device for producing liquid crystal display panel bare chips, such as Figures 1 to 5 As shown, it includes a fixing mechanism 1, which includes a fixing base 101. The inner wall of the fixing base 101 is slidably connected with two groups of top rods 102 extending to the outside of the fixing base 101, and one end of the two groups of top rods 102 located inside the fixing base 101 is fixedly connected to a support plate 103, and the inner wall of the fixing base 101 is rotatably connected to multiple groups of clamping arms 104, and the clamping arms 104 are fixedly connected to a rotating rod 105 at the connection with the fixing base 101, and the end of the rotating rod 105 is rotatably connected to one end of a connecting rod 106, and the other end of the connecting rod 106 is rotatably connected to the side wall of the support plate 103, the top ends of the two groups of top rods 102 are fixedly connected to the support rod, and the bottom end of the support plate 103 is fixedly connected to one end of a group of return springs 108, and the other end of the return spring 108 is fixedly connected to the bottom end of the inner wall of the fixing base 101.

[0027] During the inspection, the display panel die is placed above the two groups of support plates 107, so that the support plates 107 move downward under the push of the display panel die weight. In the process of the support plates 107 moving downward, the push rods 102 move downward, and the two groups of push rods 102 move downward to push the support plate 103 downward to compress the return spring 108. In the process of the downward movement of the support plate 103, the rotating rod 105 is driven to rotate through the connecting rod 106, so that the rotating rod 105 drives the clamping arm 104 to flip, so that the clamping arm 104 fits the edge of the display panel die. At this time, the clamping arm 104 is attached to the display panel die. The plate 103 is blocked and cannot be flipped further, so that the rotating rod 105 cannot be flipped, and the support plate 103 cannot move downward. At this time, the display panel bare chip is fixed. When the display panel bare chip needs to be removed, the display panel bare chip is lifted upward so that the weight of the display panel bare chip is no longer pressed on the support plate 107. At this time, the return spring 108 pushes the support plate 103 to reset, so that the support plate 103 drives the top rod 102 to reset, and the support plate 103 pushes the rotating rod 105 to rotate in the opposite direction through the connecting rod 106, so that the rotating rod 105 drives the clamping arm 104 to flip in the opposite direction, thereby releasing the display panel bare chip.

[0028] Please refer to Figure 1The top of the fixed seat 101 is fixedly connected with a cleaning mechanism 2, and the cleaning mechanism 2 includes two sets of guide frames 201. The tops of the two sets of guide frames 201 are slidably connected with a mobile box 202. The bottom end of the mobile box 202 is provided with an opening 203. The inner wall of the mobile box 202 is fixedly installed with multiple sets of fans 204. The side wall of the mobile box 202 is fixedly connected with a filter plate 205 located next to the fan 204. The cross section of the filter plate 205 is wavy. The bottom end of the mobile box 202 is fixedly connected with a cleaning strip 206 located next to the opening 203. The outer wall of the cleaning strip 206 is provided with flannel. The bottom end of the mobile box 202 is fixedly connected with a cleaning strip 206 located next to the opening 203. The silicone strip 207 next to the cleaning strip 206, the guide frame 201 includes two groups of sleeves 2011, the inner wall of each group of sleeves 2011 is slidably connected to a group of sliding rods 2012, and a guide rod 2013 is fixedly connected between the two groups of sliding rods 2012. The guide rod 2013 is slidably connected to the inner wall of the movable box 202, and the inner wall of each group of sleeves 2011 is slidably connected to two groups of friction plates 2014. The friction plates 2014 are attached to the outer walls of the sliding rods 2012, and the side walls of each group of friction plates 2014 are fixedly connected to multiple groups of spring sheets 2015. The ends of the spring sheets 2015 are fixedly connected to the inner wall of the sleeve 2011.

[0029] After the display panel die is fixed, the two sets of guide rods 2013 are pushed to drive the sliding rod 2012 to slide on the inner wall of the sleeve 2011, so that the height of the movable box 202 is changed, so that the opening 203 is close to the display panel die. Then, the movable box 202 is pushed to slide on the outer wall of the guide rods 2013 so that the opening 203 passes over the display panel die. In this process, the fan 204 blows air from the opening 203 into the movable box and then is discharged from the filter plate 205, so that the display panel die is moved downward. The dust on the sheet is sucked into and moved toward, at the same time, the cleaning strip 206 wipes the surface of the display panel die, and the silicone strip 207 scrapes the surface of the display panel die, thereby thoroughly cleaning the surface of the display panel die. Since the friction plate 2014 is tightly fitted with the sliding rod 2012 under the elastic force of the spring sheet 2015, there is a strong friction between the sliding rod 2012 and the friction plate 2014, so in the absence of human push, the sliding rod 2012 will not slide inside the sleeve 2011.

[0030] When in use, the display panel die is placed on the support plate 107, and the weight of the display panel die is used to push the top rod 102 to slide downward, thereby driving the clamping arm 104 to clamp the display panel die. After the clamping arm 104 clamps the display panel die, the top rod 102 cannot slide downward, making it more convenient and quick to fix the display panel die. The parts not involved in this device are the same as the existing technology or can be implemented using existing technology.

[0031] Although embodiments of the present invention have been shown and described, these specific embodiments are merely explanations of the present invention and are not limitations on the present invention. The specific features, structures, materials, or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions, and variations to the embodiments as needed without departing from the principles and purpose of the present invention, but as long as they are within the scope of the claims of the present invention, they are protected by patent law.
