Description

Technical Field

[0001] The utility model mainly relates to the technical field of glass thinning and etching, and in particular to a novel bottom gear tooling component for glass thinning and etching. Background Art

[0002] The current chemical thinning process includes incoming material inspection, sealing, pre-cleaning, alkaline soaking, pre-pickling, pre-treatment, main treatment, post-cleaning, outgoing material inspection, and finally shipment. Incoming material inspection focuses on inspecting the glass's surface, examining it for defects under light. Sealing requires selecting the appropriate glue type and color, needle size, dispensing pressure, sealing method, curing machine type (UV or thermal), light source position and intensity within the curing machine, curing time, whether to use a light shield, the selection of the light shield, whether to wipe the sealant, and the amount of glue seepage. Pre-cleaning process parameters vary depending on product requirements. Before starting cleaning and unloading, various parameters must be set, including the water temperature for water washing, spraying, and high-pressure spraying, pure water spray pressure, alkaline high-pressure spray pressure, pure water rinse pressure, brush pressure, brush rotation speed, drive speed, and air knife pressure. During the alkaline soaking and pre-pickling phases, a specific amount of alkaline and acid is added on a timed basis based on production requirements to ensure the cleanliness of the glass substrate surface. Pre-treatment uses a mixture of sulfuric acid and hydrofluoric acid at a specific concentration. Since sulfuric acid does not react with silica, it fills the glass surface pits, smoothing them. Hydrofluoric acid then slowly reacts with silica to suppress pits. Theoretically, within a certain range of pre-treatment thickness reduction, pit suppression is most effective.

[0003] Existing thinning and etching processes primarily utilize immersion and spray methods. Spray etching primarily utilizes top-spray etching as the primary production process. Glass substrates are loaded onto a jig for batch etching. The glass substrates are inserted vertically into the jig and then into the etching machine, where hydrofluoric acid is sprayed from the top. The current setup used in spray etching workshops, known as a setup frame, consists of a bottom tine, side tine, and side baffles. However, the bottom tine used in current spray etching tools is a full-bottom tine, with the glass edge supported by surface contact for spray etching. Due to the varying substrate glass types used by various customers in the LCD panel industry, many substrates have narrow inactive areas after cutting. During etching, the narrow edge of the substrate glass directly contacts the pin points on the bottom tine edge. As the acid reacts during etching, the glass edge contacts the pin points, resulting in uneven etching of the substrate glass and damage to the AA display area (referred to as "bottom tine acid"). This impacts the surface properties and thickness of the substrate glass, as well as the IC bonding of the subsequent module, and affects overall product quality and yield. Therefore, it is necessary to propose an improvement measure to solve the above technical problems.

[0004] It should be noted that the above content belongs to the technical knowledge scope of the inventor. Since the technical content in this field is vast and too complicated, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0007] 2. Technical solution:

[0008] In order to achieve the above-mentioned purpose, the technical solution provided by the utility model is: a new bottom tooth tooling assembly for glass thinning and etching, comprising a tooling side plate and multiple bottom tooth toolings, wherein the multiple bottom tooth toolings are distributed at intervals and installed on the tooling side plate, and the installation position of the bottom tooth tooling is adjustable; the top of the bottom tooth tooling is provided with a conical bottom rack that is converged inward, and the bottom rack is evenly spaced with multiple bottom teeth, and the middle of the bottom teeth is provided with a bottom tooth groove.

[0009] Furthermore, sliding grooves are provided on both sides of the tooling side panels, and sliders are detachably installed on both sides of the bottom gear tooling. The sliders on both sides of the bottom gear tooling are slidably installed in the sliding grooves on both sides of the tooling side panels; an extension plate is extended on one side of the slider, and a second butterfly screw is threadedly installed on the extension plate. By tightening the second butterfly screw, the slider can be limited and fixed.

[0012] 3.Beneficial effects:

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

[0014] The utility model adopts a new bottom tooth tooling assembly, in which a tapered bottom rack that converges inward is provided at the top of the bottom tooth tooling, and a bottom tooth groove is opened at the middle of the multiple bottom teeth at the top of the bottom rack. When spray etching is used to produce products with a narrow edge invalid area, surface contact is changed to point contact, the edge contact area is small, and the overall contact with the substrate glass is less.

[0028] Refer to the attached Figure 1-6The present embodiment discloses a novel bottom tooth fixture assembly for glass thinning and etching, comprising a fixture side plate 1 and a plurality of bottom tooth fixtures 2. The plurality of bottom tooth fixtures 2 are spaced apart and mounted on the fixture side plate 1, and the mounting position of the bottom tooth fixtures 2 is adjustable. A conical bottom rack 201 that converges inwards is provided on the top of the bottom tooth fixture 2. A plurality of bottom teeth 202 are evenly spaced apart on the bottom rack 201. A bottom tooth groove 2021 is provided in the middle of the bottom teeth 202. Specifically, in the present embodiment, 30 bottom tooth grooves 2021 can be arranged at equal intervals on the bottom tooth fixture 2, and the edge of the glass can be correspondingly clamped in the bottom tooth groove 2021. The bottom tooth groove 2021 mainly protrudes the bottom tooth fixture 2, changing the bottom tooth surface contact to point contact. During installation, the position of the bottom tooth fixture 2 can be adjusted according to the substrate design to avoid the glass AA area and the terminal IC binding position.

[0029] Specifically, a slide groove 101 is provided on both sides of the tooling side panel 1, and a slider 3 is detachably installed on both sides of the bottom gear tooling 2. The sliders 3 on both sides of the bottom gear tooling 2 are slidably installed in the slide grooves 101 on both sides of the tooling side panel 1; an extension plate 301 is extended on one side of the slider 3, and a second butterfly screw 6 is threadedly installed on the extension plate 301. By tightening the second butterfly screw 6, the slider 3 can be limited and fixed.

[0030] A vertical plate 4 is correspondingly provided on the top of the slider 3, and a mounting hole is correspondingly opened on the vertical plate 4, and a first butterfly screw 5 is correspondingly provided in the mounting hole; threaded holes 203 are correspondingly opened at both ends of the bottom gear tooling 2, and the first butterfly screw 5 passes through the mounting holes on the vertical plate 4 and is correspondingly threadedly installed in the threaded holes 203 on the end face of the bottom gear tooling 2. The bottom gear tooling 2 can be installed by tightening the first butterfly screw 5. The bottom gear tooling 2 is installed and fixed on the tooling side plate 1 of the setting frame by the first butterfly screw 5, and can be used after being tightened.

[0031] In this embodiment, a tapered bottom rack 201 that converges inward is provided at the top of the bottom tooth tooling 2, and a bottom tooth groove 2021 is opened at the middle of the multiple bottom teeth 202 at the top of the bottom rack 201. When spray etching is used to produce products with a narrow edge invalid area, surface contact is changed to point contact, the edge contact area is small, and the overall contact with the substrate glass is less. The position of the bottom tooth tooling 2 can be adjusted according to the glass design, thereby adjusting the support position, avoiding the effective area and the terminal IC binding position during support, so that uneven edge etching and abnormal edge plate thickness will not occur, avoiding uneven etching, abnormal plate thickness and affecting the abnormal terminal IC binding of the rear module due to contact with the surface during the etching process, and solving the current problems of uneven etching, abnormal plate thickness and affecting the abnormal terminal IC binding of the rear module due to full bottom teeth in the spray line. Compared with the traditional surface contact full bottom tooth insert, it has a smaller overall weight and width, does not increase the difficulty during installation, is simpler and more convenient to install, does not require employees to perform complex operations, and is more practical.

[0032] The main material of the bottom gear tooling 2 is acid-resistant PVC. On the one hand, the acid-resistant PVC material is lighter, and the tooling side panel 1 is convenient for carrying more at one time, so that more substrates can be produced in each batch. On the other hand, the acid-resistant PVC can effectively prevent damage from acid during the etching process.

[0033] 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.
