Technical Field

The utility model belongs to the technical field of liquid crystal display, specifically speaking, the utility model relates to a set for frame abacus pearl is etched in soaking.

Background

With the trend of increasing the size and thinning of electronic consumer products such as mobile phones and tablet computers, the requirement for thinning glass substrates is increasing, the requirement for various liquid crystal display screens in real life is increasing, the liquid crystal display screens gradually tend to develop in the direction of increasing the size and decreasing the thickness, and therefore the technical level of enterprises in the industry needs to be increased continuously under the condition of ensuring the qualification rate and the product quality and having the technical strength for processing the glass substrates with larger sizes. Currently, the thinning modes in the thinning industry are mainly physical grinding and chemical etching, wherein the chemical etching is the most important thinning mode.

The chemical etching mode mainly comprises spray etching and soaking etching, and the existing processing technology of thinning the liquid crystal panel with the size of G4.5 or more from 1.0mm to 0.3mm through soaking etching has poor side tooth positions and is higher than that of spray etching. Compared with the spray etching which is influenced by the flow, the soaking etching is influenced by factors such as foaming, etching rate, acid liquor concentration, glass powder accumulation and the like, and the problems of large plate thickness difference, uneven acid etching and the like easily occur locally; one of the existing jigs used for immersion etching is an abacus bead which is used for limiting a certain number of substrates, but the abacus bead has the defects of large contact area with the substrates, long effective limiting length and the like, and the substrates are easy to have the problems of empty clamping, cracking, damage, large thickness difference and local upper limit caused by the abacus bead in the etching process.

The prior immersion etching abacus bead has the following defects:

disadvantage 1: the maximum limit length of the existing abacus bead is 10mm, the tool main body is a solid body, so that the narrow frame product of the G4.5-sized substrate has liquid resistance and overlong limit in the tool limit area, the tooth positions of the side teeth of the substrate have uneven tooth position acid etching and tooth position pits, and the reject ratio is up to more than 30%;

and (2) disadvantage: the maximum limit length of the abacus bead with the minimum effective limit area is about 10mm, after the substrate with the size of G4.5 is etched, the plate thickness difference of the tooth position is very large (about 35 mu m/piece), the local upper limit of the plate thickness of the substrate or the uneven acid etching can be caused by the influence of foaming blowing, glass powder accumulation and the like in the etching process, and the risk of poor damage generation in the post-processing is higher;

disadvantage 3: the contact area between each type of abacus bead and the substrate is large, the requirement on the use waste liquid area of HF solution is high, and the production cost is increased; and the gear position of the substrate is easy to generate larger plate thickness difference and uneven etching, thereby influencing the apparent yield of the substrate.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving one of the technical problem that exists among the prior art at least. Therefore, the utility model provides a set up abacus pearl is etched in soaking, the purpose is to improve the product yield.

In order to realize the purpose, the utility model discloses the technical scheme who takes does: set for frame abacus pearl soak etching, including the frock main part with set up in a plurality of dogteeth of frock main part one side at least, the dogtooth is circular truncated cone shape structure, lies in the frock main part and arranges in proper order for the length direction along the frock main part with all dogteeth of one side.

The opposite sides of the tool main body are provided with the convex teeth.

The middle part of the tool main body is hollow, a support column is arranged in a center hole of the tool main body, and the support column is connected with the tool main body.

Detailed Description

The following detailed description of the embodiments of the present invention will be given with reference to the accompanying drawings, for the purpose of helping those skilled in the art to understand more completely, accurately and deeply the conception and technical solution of the present invention, and to facilitate its implementation.

As shown in fig. 1 to 6, the utility model provides a set for frame abacus pearl is etched in soaking, including frock main part 1 with set up in a plurality of dogtooths 2 of 1 at least one side of frock main part, dogtooth 2 is circular truncated cone shape structure, lie in frock main part 1 with all dogtooths 2 of one side for arranging in proper order and for the equidistance distribution along the length direction of frock main part 1. When the glass substrate limiting device is used, the convex teeth 2 play a limiting role on the glass substrate, the glass substrate is embedded between the two adjacent convex teeth 2, and the outer circular surfaces of the convex teeth 2 are in contact with the glass substrate.

Specifically, as shown in fig. 1 to 3, the tool body 1 is provided with the convex teeth 2 on two opposite sides, and the tool body 1 is provided with the same number of convex teeth 2 on two opposite sides. The arrangement of the cone frustum-shaped convex teeth 2 keeps the advantages of the original spray fixture and the immersion of the abacus beads, thereby not only ensuring the limiting effect of the abacus beads on the glass substrate, but also reducing the contact area of the abacus beads on the glass substrate. And the formed immersion etching is set for the abacus bead, so that the liquid resistance of the tool can be effectively reduced, the requirement on the area of the acid liquor waste liquid is relatively low, the utilization rate of the acid liquor can be improved, and the production cost is reduced.
