[0032] The present application provides a panel cleaning jig for carrying a panel to facilitate wiping and cleaning the panel, so as to ensure that the surface of the panel is free of foreign matter or dust, thereby ensuring product quality and avoiding the flow of defective products into the market.

[0033] The structure of the panel cleaning jig in the present application will be described below with reference to a liquid crystal panel as an example, which is used to be bonded with a glass cover plate or an optical film to form a liquid crystal display screen. It can be understood that in other embodiments, the panel cleaning jig of the present application is not limited to being used only to carry a liquid crystal panel, but can also carry any panel, such as a glass panel or a plate-shaped product made of other materials, which is not limited here.

[0034] Referring to Figure 1 , Figure 1The panel cleaning jig 10 provided by the embodiment of the present application is shown in the axial side view. The panel cleaning jig 10 provided by the embodiment of the present application comprises a base 100, a driving assembly 200 and a jig body 300. The jig body 300 is slidingly arranged on the base 100. The driving assembly 200 is arranged on the base 100 and is drivingly connected to the jig body 300. The base 100 is used to support the driving assembly 200 and the jig body 300. The jig body 300 is used to carry the liquid crystal panel, so that the liquid crystal panel can be fixed on the jig body 300, thereby facilitating the worker to clean. The driving assembly 200 is used to drive the jig body 300 to move from a cleaning station to a discharging station.

[0035] Specifically, as shown in the figure, the driving assembly 200 comprises a driving source 210, a lead screw 220 and a lead screw nut 230. The lead screw 220 is connected to the driving source 210. The lead screw nut 230 is movably sleeved on the lead screw 220. The jig body 300 is connected to the lead screw nut 230. Under the driving of the driving source 210, the lead screw 220 can rotate around its central axis to drive the lead screw nut 230 and the jig body 300 to move relative to the base 100 along the direction in which the central axis of the lead screw 220 extends. Figure 1

[0036] By arranging the jig body 300 to be movable relative to the base 100, after the worker completes the cleaning of the liquid crystal panel at the cleaning station, the jig body 300 can automatically move to the discharging station while carrying the liquid crystal panel. Therefore, the long-time manual carrying of the liquid crystal panel can be avoided, the touching of the liquid crystal panel is reduced, and the secondary pollution of the liquid crystal panel is avoided.

[0037] In other embodiments, the lead screw 220 can also be manually rotated around its central axis. However, it is undoubtedly that the driving of the lead screw 220 around its central axis by the driving source 210 can improve the automation degree of the jig.

[0038] Preferably, a plurality of sliding rails 400 parallel to the lead screw 220 are arranged on the base 100. A sliding block is slidingly arranged on each sliding rail 400. The jig body 300 is connected to the sliding rails 400, so that the sliding rails 400 and the sliding blocks can play a guiding role to avoid the deviation of the jig body 300 from the moving track during the movement, and the movement is more stable.

[0039] The specific structure of the jig body 300 is shown in the figure. Figure 2 ​The jig body 300 comprises a first support base 310 and a second support base 320 which are integrally connected. The first support base 310 has a support surface 301. The second support base 320 is connected to the support surface 301. The projection of the second support base 320 on the support surface 301 is entirely located within the support surface 301 and is located in the middle of the support surface 301, so that a stepped surface 302 is formed around the second support base 320 on the support surface 301.

[0040] In this way, by forming the stepped surface 302 around the second support base 320 on the support surface 301, not only can the liquid crystal panel be placed on the jig for wiping and cleaning, but also the foreign matter or dust cleaned from the liquid crystal panel can fall on the stepped surface 302 and not fall on the base 100 or the table, so that the table can be prevented from being contaminated and difficult to clean.

[0041] On the basis of this embodiment, a recovery groove 303 is formed around the second support base 320 on the stepped surface 302. By forming the recovery groove 303, the foreign matter or dust wiped from the liquid crystal panel can fall into the recovery groove 303, so that the foreign matter or dust can be prevented from falling from the stepped surface 302 to the base 100, and thus the foreign matter or dust can be easily cleaned.

[0042] Further, as shown in Figure 2 and Figure 3 , in one embodiment, the upper surface of the jig body 300 (i.e. the side surface of the second support base 320 away from the support surface 301) is a fixed surface 304. A plurality of vacuum suction holes 305 are formed on the fixed surface 304. The panel cleaning jig 10 further comprises a vacuum suction assembly connected to the second support base 320. The vacuum suction assembly is used to generate airflow through the vacuum suction holes 305, so that the liquid crystal panel can be adsorbed on the fixed surface 304 by vacuum adsorption.

[0043] By vacuum adsorbing the liquid crystal panel on the fixed surface 304, the liquid crystal panel can be prevented from shaking back and forth during wiping and cleaning, which can cause defects. After the liquid crystal panel is cleaned, the liquid crystal panel can be directly detected on the jig, which can prevent the liquid crystal panel from being taken out for detection and causing secondary pollution to the liquid crystal panel. The pollution and damage to the liquid crystal panel are reduced, and the production quality of the product is ensured.

[0044] In order to have a better vacuum adsorption effect, as shown in Figure 3As shown, the first support base 310 is provided with a groove on the side away from the second support base 320, the jig further comprises a bottom cover 600, the bottom cover 600 covers the opening of the groove, the groove wall and the bottom cover 600 jointly form a vacuum cavity 11, the vacuum cavity 11 is communicated with the vacuum suction hole 305, the side surface of the second support base 320 is further provided with a vent hole, the vent hole is communicated with the vacuum cavity 11 and connected with the vacuum suction assembly. In this way, when vacuumizing, more air can be gathered in the vacuum cavity 11, and the vacuum suction assembly can suck the large amount of air gathered in the vacuum cavity 11, thereby generating a larger suction force to make the suction more firm.

[0045] Preferably, the groove comprises a first groove body and a second groove body, the second groove body is provided on the bottom wall of the first groove body and extends to the inside of the second support base 320, the bottom cover 600 is connected to the jig body 300 by a plurality of fasteners and is attached to the bottom wall of the first groove body, and the side of the bottom cover 600 away from the groove is flush with the side of the first support base 310. This design can save space and make the jig more beautiful.

[0046] In the structure of the vacuum suction assembly, the vacuum suction assembly comprises a gas pipe joint 500, a gas pipe and a vacuum pump, Figure 2 In the embodiment shown in the middle, the gas pipe joint 500 has two, and the vent hole also has two correspondingly, each gas pipe joint 500 is arranged at one end of a corresponding vent hole, and the gas pipe also has two, one end of each gas pipe is connected to the gas pipe joint 500, and the other end is connected to the vacuum pump. The gas pipe joint 500 helps to fix the gas pipe and avoid the gas pipe from falling off, and the vacuum pump is used to generate negative pressure to generate suction force for adsorbing the liquid crystal panel.

[0047] Further, the vacuum suction holes 305 are arranged in an array and uniformly, so that the liquid crystal panel placed on the fixing surface 304 can be subjected to uniform suction force, which helps to enhance the positioning effect.

[0048] It is worth noting that since the specifications of the liquid crystal panel have many kinds, their sizes are also different, and the length and width dimensions of some liquid crystal panels are larger than those of the second support base 320, which causes the four peripheral edges of the liquid crystal panel to be in a suspended state when the liquid crystal panel is placed on the fixing surface 304. When the liquid crystal panel is cleaned, the four peripheral edges of the liquid crystal panel may be easily damaged due to lack of support when subjected to pressing force, resulting in appearance defects or functional defects.

[0049] To solve this problem, in a preferred embodiment, as Figures 2 to 4As shown, the cross section of the second support base 320 is quadrangular, and each of the four sides of the second support base 320 is movably provided with a clamping portion 700, and each clamping portion 700 is connected to the second support base 320 by a self-locking leaf 800, so that each clamping portion 700 can rotate around an axis extending along the edge of the second support base 320, and can be fixed in an open position relative to the second support base 320 or a closed position relative to the second support base 320.

[0050] Therefore, when the length and width of the liquid crystal panel are larger than the length and width of the second support base 320, all the clamping portions 700 are in the open position relative to the second support base 320, so that when the liquid crystal panel is wiped, the edges of the liquid crystal panel can be supported by the clamping portions 700, so that the edges of the liquid crystal panel are not easily damaged by the pressing force to cause appearance defects or functional defects. When the liquid crystal panel is not placed on the fixing surface 304 or the length and width of the liquid crystal panel are smaller than the length and width of the second support base 320, all the clamping portions 700 can be closed relative to the second support base 320 to be in the closed position, so that space can also be saved.

[0051] As an improvement of the above embodiment, each clamping portion 700 is also provided with an avoiding groove (not shown) extending through the opposite sides of the clamping portion 700, so that when the cleaning is completed, the edges of the liquid crystal panel can be easily taken by a person or a mechanical hand, and the situation that the liquid crystal panel cannot be taken due to the thin thickness of the liquid crystal panel can be avoided.

[0052] In addition, in order to facilitate the separate carrying of the jig body 300, the first support base 310 and the second support base 320 are respectively provided with a plurality of sliding grooves 302 and 304. Figure 5 As shown, the jig body 300 is provided with a hand holding groove 306 on the opposite sides, and it can be understood that the hand holding groove 306 can be provided on the opposite sides of the first support base 310 or the second support base 320, and is not limited herein. When the jig body 300 is carried separately, the fingers or clamping jaws of the worker can be inserted into the hand holding groove 306 to facilitate holding, so that the jig body 300 can be prevented from falling during carrying.

[0053] It should be noted that the panel cleaning jig 10 provided in the present application can also only include the jig body 300 without the base 100 and the driving assembly 200, but it is obvious that the sliding connection of the jig body 300 to the base 100 can better reduce the contact of the worker with the liquid crystal panel, and it is obviously the best embodiment.

[0054] Therefore, when the liquid crystal panel is cleaned by the panel cleaning jig 10 provided by the application, the liquid crystal panel and the table top form a height difference, and the foreign matter or dust on the liquid crystal panel can be wiped off to the stepped surface 302 of the jig body 300 or the recycling groove 303 opened in the stepped surface 302, thereby avoiding pollution of the base 100 or the table top, facilitating cleaning; and when the liquid crystal panel is tested by the worker, the worker's hand is prevented from contacting the liquid crystal panel as much as possible, secondary pollution of the liquid crystal panel is avoided, surface damage of the liquid crystal panel is reduced, the quality of the product is effectively ensured, and the defective product is prevented from flowing into the market.

[0055] The technical features of the above-described embodiments can be combined in any manner. To make the description concise, all possible combinations of the technical features in the above-described embodiments are not described, but as long as the combinations of the technical features do not contradict each other, they should be considered within the scope of the present disclosure.

[0056] The above-described embodiments only express several implementation manners of the application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the patentable scope of the application. It should be pointed out that for ordinary skilled persons in the art, some modifications and improvements can be made without departing from the concept of the application, and these all belong to the protection scope of the application. Therefore, the patent protection scope of the application should be subject to the appended claims.
