Abstract
Description
Technical Field
[0001] The utility model relates to the field of jigs, and particularly to an alignment jig for the screen printing alignment lines of a cover plate. Background Art
[0002] For current cover plate products, since they need to be bonded to a display screen or some auxiliary materials need to be pasted and components need to be installed on the back of the cover plate at the whole machine end, it is often necessary to print alignment lines on the back of the cover plate to ensure the position accuracy of the subsequent component assembly. Therefore, the printing accuracy requirements for the alignment lines on the cover plate are relatively high, and generally, the position accuracy is required to be controlled within ±0.1 mm.
[0003] When screen printing the alignment lines, since there are often no features on the alignment line layer that can be directly aligned with the outer shape of the cover plate, the printing equipment cannot accurately control the rotation and position accuracy, resulting in a large deviation in the printing size.

BRIEF DESCRIPTION OF THE DRAWINGS
[0020] In order to more clearly illustrate the technical solutions of the embodiments of the present utility model, the drawings required to be used in the embodiments will be briefly introduced below.
[0021] Figure 1 It is a schematic structural diagram of an alignment fixture for a cover plate screen printing alignment line in an embodiment of the present utility model.
[0022] Reference numerals:
[0023] Substrate 10, alignment identification pattern 20, cover plate alignment area 30. DETAILED DESCRIPTION OF THE EMBODIMENTS
[0024] To facilitate the understanding of the present utility model, the present utility model will be described more comprehensively below with reference to the relevant drawings.
[0025] The present application provides an alignment fixture for a cover plate screen printing alignment line, which is applied to the cover plate screen printing alignment line and the cover plate is placed therein. When other parts are attached to the cover plate, the alignment line plays a role in accurate attachment, avoiding part misalignment and affecting the overall assembly of the parts on the cover plate.
[0026] Specifically, please refer to Figure 1, the alignment fixture for the cover plate silk screen alignment line includes: a substrate 10 and an identification component. A cover plate alignment area 30 is provided on the substrate 10, and the cover plate alignment area 30 is used to place the cover plate. The identification component is arranged on the four peripheral edges of the cover plate alignment area 30 to identify the alignment accuracy between the cover plate and the cover plate alignment area 30. The cover plate is placed in the cover plate alignment area 30. Through the identification of the cover plate by the staff using the identification component, the cover plate is continuously adjusted to a more accurate position in the cover plate alignment area 30, enabling the cover plate to be accurately aligned in the cover plate alignment area 30, greatly reducing the positioning error of the cover plate in the cover plate alignment area 30, achieving technological breakthroughs such as clear identification, accurate positioning, and easy automatic recognition by printing equipment, and improving the printing accuracy of the alignment line layer on the cover plate, thereby improving the alignment and placement accuracy of other modules on the cover plate.
[0027] It should be noted that the shape of the cover plate alignment area 30 is the same as the shape of the cover plate.
[0028] Please refer to again Figure 1 , in an embodiment, the cover plate alignment area 30 is rectangular. The identification component includes two alignment identification patterns 20, and the alignment identification patterns 20 are arranged at two diagonals of the cover plate alignment area 30. The alignment identification patterns 20 define the placement position of the cover plate in the cover plate alignment area 30, making it easier for the naked eye to observe the accuracy limitation of the cover plate by the alignment identification patterns 20.
[0029] It should be noted that the alignment identification patterns 20 are clearly identified in the substrate, and their colors are completely different. The alignment identification patterns 20 are in dark color systems such as pink and black, and the substrate is in light color systems such as white and transparent.
[0030] In another embodiment, the cover plate alignment area 30 is still rectangular, and the identification component includes four alignment identification patterns 20. The alignment identification patterns 20 are arranged at the four right angles of the cover plate alignment area 30, comprehensively improving the alignment accuracy of the alignment identification patterns 20 for the cover plate in the cover plate alignment area 30.
[0031] Preferably, the alignment identification pattern 20 is in an "L" shape.
[0032] It should be noted that to avoid the alignment identification patterns 20 from being printed as well, the four alignment identification patterns 20 need to be filled with a compensating screen paste before printing. After filling, the ink used for printing the alignment line cannot penetrate into the alignment identification patterns 20 and thus cannot be printed. Moreover, although the alignment identification patterns 20 are filled with the compensating screen paste, the color difference between the screen paste and the screen yarn of the screen tool enables the outer shape of the alignment identification patterns 20 to be recognized by the naked eye and the printing equipment. Therefore, by overlapping and aligning the alignment identification patterns 20 with the outer shape of the four corners of the cover plate, the accuracy of the rotation of the alignment line layer printing and the attachment position of other modules is ensured.
[0033] In one embodiment, the connection lines of the four alignment mark patterns 20 form a rectangle, such that the four alignment mark patterns 20 are precisely arranged at the edge of the cover plate alignment area 30.
[0034] Furthermore, a border line is provided at the edge of the cover plate alignment area 30, and each part of the cover plate is placed within the border line, which can further limit the cover plate.
[0035] Still further, the thickness of the border line is 0.01 mm.
[0036] In one embodiment, the inner sides of the alignment mark patterns 20 are tangent to the right angles of the cover plate alignment area 30 respectively, such that the alignment mark patterns 20 fit the cover plate in the cover plate alignment area 30 better.
[0037] Furthermore, the alignment mark patterns 20 and the substrate 10 have different colors, making the alignment mark patterns 20 easier to be recognized.
[0038] In addition, a ventilation opening is formed on the cover plate alignment area 30. When the cover plate is unloaded, the ventilation opening can balance the air pressures among the cover plate, the substrate 10 and the atmospheric pressure, enabling the cover plate to be unloaded easily.
[0039] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
