TECHNICAL FIELD
[0001] The utility model relates to display module technical field especially relates to a structure of promoting FPC bending precision. BACKGROUND
[0002] In the production process of display module, the module FPC in display module needs to be attached on the back of display module after being bent, and the module FPC bending action is completed by automatic machine currently, and the module FPC is bent by clamping mechanism after being recognized by visual device, and the bending precision is not high due to the inaccurate alignment of machine when the machine bends, and the FPC is damaged when the machine clamps module FPC, which affects production efficiency and product yield.
[0003] Therefore, the prior art has defects and needs to be improved. UTILITY MODEL CONTENT
[0004] The utility model aims at overcoming the shortage of at least part prior art, and provides a structure of promoting FPC bending precision.
[0005] The utility model discloses a structure of FPC bending precision, including: display glass subassembly and module FPC, module FPC is bounded with display glass subassembly connection, module FPC includes the body, the left side and / or right side on the body outwardly extended and formed at least one identification and catch, the identification and catch has the identification structure that can be recognized by the visual device of machine, and the identification and catch can be taken by the clamping device of machine, the body with identification and catch between form has the pre-break line.
[0006] Further, the identification structure includes the shape edge of the identification and catch.
[0007] Further, the identification and catch includes one length greater than or equal to 3mm and the shape edge of horizontal or vertical setting.
[0008] Further, the identification and catch does not exceed the maximum shape edge of the body in horizontal.
[0009] Further, the scheme still includes backlight module, and the backlight module is laminated and arranged in the lower layer of display glass subassembly, and the joint of the backlight FPC of backlight module is welded on the backlight welding area of the body of module FPC.
[0010] The beneficial effects of the display module structure for improving FPC bending precision are as follows: the identification and grabbing part provided on the module FPC can be used for identification and taking by the machine table when the module FPC is bent, the positioning accuracy of the machine table is improved, the bending accuracy is improved, the problem of damage of the module FPC body caused by taking the module FPC by the machine table is avoided, and the production efficiency and yield are improved. BRIEF DESCRIPTION OF DRAWINGS
[0011] Figure 1 It is a structural schematic view of an embodiment of the utility model.
[0012] Figure 2 It is Figure 1 It is an enlarged view of A in the figure. DETAILED DESCRIPTION
[0013] The utility model will be explained in detail in combination with the drawings and specific embodiments.
[0014] Please combine with Figure 1 And Figure 2 In the embodiment, the utility model provides a kind of display module structure for improving FPC bending precision, comprising: display glass component 2 and module FPC 1, the module FPC 1 is bound with the display glass component 2 connection, the module FPC 1 includes body 11, left side and / or right side on the body 11 extend outward and form an identification and grabbing part 12, the identification and grabbing part 12 has the identification structure that can be identified by the visual device of machine table, and the identification and grabbing part 12 can be taken by the clamping device of machine table, by the identification and grabbing part 12 set, when machine table is bent operation, the identification structure in the identification and grabbing part 12 can be identified, the accurate alignment to the module FPC 1 is realized, and the identification and grabbing part 12 can be clamped in bending, the bending of the module FPC 1 is realized, avoid because contact stress and damage the body 11 of the module FPC 1.The body 11 and the identification and grabbing part 12 form pre-break line 13, facilitate subsequent separation of the identification and grabbing part 12 and the body 11 by the mode of tearing off the pre-break line 13.
[0015] Further, the identification structure is the shape edge of the identification and grabbing part 12, so that machine table can realize the positioning of the module FPC 1 by identifying the shape edge. In order to guarantee good identification effect, the identification and grabbing part 12 needs to include a length greater than or equal to 3mm and the shape edge set horizontally or vertically, and in the embodiment, the identification and grabbing part 12 includes a vertical shape edge with a length of 3.5mm, and a horizontal shape edge with a length of 4.5mm forming a right angle with the vertical shape edge, which can meet the positioning identification requirement, and also can guarantee that the identification and grabbing part 12 can have enough area for the clamping device of machine table to take.
[0016] Further, the identification and grabbing part 12 does not exceed the maximum outer shape side of the body 11 in the lateral direction, so that the area required by the module FPC 1 during the manufacturing process of the module FPC 1 can be avoided to increase, thereby avoiding the cost increase.
[0017] Further, the scheme further comprises a backlight module, the display glass assembly 2 is a liquid crystal display glass assembly, the backlight module is stacked on the lower layer of the display glass assembly 2, and the joint of the backlight FPC of the backlight module is welded on the backlight welding area of the body 11 of the module FPC 1.
[0018] In summary, the beneficial effects of the scheme are that: by setting the identification and grabbing part which can be quickly torn off on the module FPC for the machine to identify and take when the module FPC is bent, the machine alignment accuracy can be improved, thereby improving the bending accuracy, avoiding the problem of the damage of the body of the module FPC caused by the machine taking the module FPC, and improving the production efficiency and yield.
[0019] The above is only a preferred embodiment of the utility model, and is not used for limiting the utility model, and any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model.
