Description

Technical Field

[0001] The utility model mainly relates to the technical field of glass thinning jigs, and in particular to a tooling jig for thinning a glass substrate. Background Art

[0002] The glass substrate thinning is based on ordinary thinning. The glass contacts the bottom teeth of the tooling, and other processes are produced according to the original ordinary thinning. This will lead to uneven etching of the bottom edge and easy occurrence of edge collision and leakage. We are now improving the quality of the bottom plate and redesigning the fixture to prevent leakage and product scrapping, thus solving the current abnormal leakage.

[0003] The current thin-film chemical fixture uses a full-bottom-teeth vertical insert with the bottom teeth. The edge of the glass directly contacts the bottom teeth. As the glass substrate becomes thinner during the etching process, a slight impact or movement can cause the glass corner plastic frame to stretch, causing acid to leak from the stretching area and causing the bottom plate to be scrapped. This fixture changes the glass edge from full contact to point contact, reducing the risk of stretching and leakage.

[0004] The inventors proposed a tooling jig for thinning glass substrates. The tooling jig provides support for the plastic frame outside the glass substrate by setting bottom teeth, and sets limit points on the bottom teeth to limit the placement of the plastic frame on the bottom teeth. Compared with the surface contact between the traditional jig and the plastic frame, which results in greater force, the contact between the limit points and the plastic frame is point contact, which reduces the force between the plastic frame and the jig. The reserved gaps between the limit points provide deformation space for the plastic frame, thereby preventing the plastic frame from being deformed due to excessive force, which leads to a decrease in the yield rate of glass substrate thinning. Utility Model Content

[0006] The utility model provides a tooling fixture for glass substrate thinning, which solves the technical problem of existing equipment that the plastic frame is subjected to excessive force on the fixture, resulting in a reduced yield rate of glass substrate thinning.

[0009] Furthermore, the top surface of the bottom teeth contacts the bottom of the plastic frame, and spacing grooves are reserved between adjacent bottom teeth.

[0013] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0014] The utility model provides a tooling fixture for thinning glass substrates. The hemispherical end design of the limit point prevents the limit point from scratching the end face of the glass substrate, ensuring point contact between the limit point and the external plastic frame of the glass substrate.

On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0027] It should be noted that when an element is referred to as being "fixed on" another element, it may be directly on the other element or there may also be an element in the middle; when an element is considered to be "connected to" another element, it may be directly connected to the other element or there may also be an element in the middle; the terms "vertical", "horizontal", "left", "right" and similar expressions used in this article are for illustrative purposes only.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the art to which this invention pertains; the terms used herein in the specification of this invention are for the purpose of describing specific embodiments only and are not intended to limit this invention; the term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] Refer to the attached Figure 1-4 The utility model provides a tooling fixture for thinning a glass substrate, comprising a glass substrate 1, a plastic frame 2 bonded to the outer side of the glass substrate 1, and a bottom plate 3. The top surface of the bottom plate 3 is fixed with a plurality of bottom teeth 4, and the top of the bottom teeth 4 is fixed with a plurality of limit points 5.

[0030] In this embodiment, the top surfaces of the bottom teeth 4 are in contact with the bottom of the plastic frame 2 , and spacing grooves 41 are reserved between adjacent bottom teeth 4 .

[0031] The bottom teeth 4 provide support for the plastic frame 2 outside the glass substrate 1. The bottom teeth 4 cooperate with the bottom plate 3 to arrange multiple glass substrates 1 at intervals. The spacing grooves 41 are designed to reserve processing gaps between adjacent glass substrates 1.

[0032] In this embodiment, the top of the limiting point 5 is fixedly set to be hemispherical, the outer side of the limiting point 5 is engaged with the bottom outer side of the plastic frame 2, and multiple limiting points 5 are arranged symmetrically or staggered about the middle of the bottom teeth 4.

[0033] The hemispherical end design of the limit point 5 prevents the limit point 5 from scratching the end face of the glass substrate 1, ensuring point contact between the limit point 5 and the external plastic frame 2 of the glass substrate 1. At the same time, the limit points 5 are symmetrically or staggeredly arranged, that is, the space between adjacent limit points 5 is reserved for a certain deformation of the plastic frame 2 after being subjected to force, thereby completing the point contact assembly of the fixture and the plastic frame 2. The installation operation is relatively simple and does not require employees to perform multiple complex debugging operations later. The bottom of the glass substrate 1 is only in contact with very individual points, which protects the glass substrate 1 and reduces the risk of liquid leakage.

[0034] In this embodiment, a protrusion is fixedly provided continuously and / or discontinuously on the middle portion of the bottom teeth 4 , and the top surface of the protrusion contacts the bottom of the plastic frame 2 .

[0035] The raised portion on the bottom teeth 4 reduces the contact area between the top surface of the bottom teeth 4 and the bottom of the bottom frame, thereby providing a certain deformation space for the plastic frame 2 when the glass substrate 1 is subjected to stress during subsequent processing.

[0036] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
