Detailed Description
In order that those skilled in the art will better understand the technical solutions of the present invention, the following detailed description of the present invention is provided in conjunction with the accompanying drawings, and the description of the present section is only exemplary and explanatory, and should not be construed as limiting the scope of the present invention in any way.
Fig. 1 and 2 are schematic views illustrating a first embodiment of the present application, including a backplate 10 and a base 20 connected to the bottom of the backplate 10; one side surface of the back plate 10 is set as a working surface 11; the surface of the base 20 is inwards recessed with a slot 21, the wall surface of one side of the slot 21 is flush with the working surface 11, and one side of the base 20 far away from the working surface 11 is provided with a downward inclined surface 22. In this embodiment, backplate 10 can be dismantled with base 20 through the mode of joint and be connected, consequently can change the base 20 model of using different according to the model of different small-sized liquid crystal display to increase the flexibility that the tool was used.
The tool of this embodiment is used for the coating film link of the surface treatment process of the small-sized liquid crystal display after the big board cutting, and the vertical grafting of small-sized liquid crystal display makes small-sized liquid crystal display's exposed terminal insert in the slot 21 on base 20. Preferably, the depth of the insertion groove 21 is set to 4mm, so that the depth of the insertion groove 21 is consistent with the width of the exposed terminal, that is, the exposed terminal part of the small-sized liquid crystal display panel is completely inserted into the insertion groove 21. In this embodiment, make the TF table of small-size liquid crystal display and the working face 11 laminating of backplate 10 through the width of reasonable design slot 21 to guarantee the steadiness that the coating film in-process, the display screen was placed on the tool. Preferably, the width of the insertion groove 21 is set to 0.5mm so that the width of the insertion groove 21 corresponds to the thickness of the bare terminal.
