Description

Technical Field

[0001] The invention mainly relates to the technical field of glass cutting, and in particular to a novel touch screen protective glue cutting process. Background Art

[0002] At present, the screen printing process of peelable adhesive in the touch screen industry is designed according to the product's graphic size (each small piece) and is produced and printed by screen printing. There is a 0.5mm area (reserved for cutting) from the outer edge of the product to the peelable adhesive edge, which is a blank area not covered by the peelable adhesive. This blank area will cause the tape to stick when the product is automatically peeled off, resulting in abnormal film tearing (fragmentation). After the peelable adhesive is torn off, there will be abnormalities such as peelable adhesive edge marks, dirt, residue, and fingerprints. The schematic diagram of the coordination of the glass substrate and the peelable adhesive in the product processed in the prior art refers to the attached figure in the specification. Figure 2 and Figure 3 .

[0003] The existing cutting equipment (infrared laser / knife wheel) on the market cannot directly cut products with peelable adhesive. The peelable adhesive will affect the transmission of the infrared laser light source, and the angle and teeth of the conventional knife wheel cannot cut the product in the (peelable adhesive + product) state.

[0004] Since customers often complain about the difficulty in starting the peelable adhesive film and the dirty marks on the peelable adhesive film, the inventor has proposed a new touch screen protective adhesive cutting process. By redesigning the structure of the cutter wheel, the cutter wheel is convenient for the complete cutting of the glass substrate and the protective layer, avoiding the traditional cutter wheel's inability to cut the glass substrate normally or the occurrence of burrs or peeling when cutting the protective layer. The glass substrate of the product cut by the improved cutter wheel is completely covered by the protective layer, avoiding technical problems such as oil printing and dirt on the glass substrate in subsequent operations. Summary of the invention

[0005] 1. Technical problems solved by the invention: The invention provides a novel touch screen protective glue cutting process, which solves the technical problem that the product becomes dirty or the protective layer is damaged when the existing equipment cuts the blank substrate combined with the glass substrate and the protective layer.

[0006] 2. Technical solution: To achieve the above object, the technical solution provided by the present invention is: a new touch screen protective glue cutting process, comprising the following steps: The protective layer covers the glass substrate, and the protective layer forms a blank substrate after drying.

[0007] Fix the blank substrate on the workbench, and the linear module moves the workbench to the bottom of the gantry three-coordinate machine.

[0008] The gantry three-coordinate mobile cutting mechanism moves the cutter wheel to the top of the blank substrate. The cutting mechanism changes the pressure of the cutter wheel on the blank substrate through the preset lifting module.

[0009] Use the cutting wheel to cut the blank substrate according to the preset different product specifications.

[0010] Furthermore, the top of the glass substrate is divided into a cutting surface, and the entire cutting surface is covered with a protective layer, and the protective layer is a peelable adhesive.

[0011] The improved cutter wheel can cut the blank substrate composed of the peelable adhesive and the glass substrate, wherein the cut edge of the blank substrate is free of peelable adhesive burrs and cracks, so the peelable adhesive can completely cover the glass substrate, and there is no need to make more requirements on the printing range and shape of the peelable adhesive on the glass substrate, which simplifies the processing flow of the blank substrate and saves the production cost of the peelable adhesive silk screen.

[0012] At the same time, the peelable adhesive completely covers the glass substrate, and in the subsequent peelable adhesive peeling operation, it is convenient for the user to peel the peelable adhesive from the glass substrate, and the film peeling operation is convenient to operate.

[0013] Furthermore, the protective layer construction process of the glass substrate includes the following steps: The cutting blade surface of the glass substrate is cleaned.

[0014] Place the cleaned glass substrate and adjust the cutting blade surface to be level.

[0015] The protective layer is covered on the horizontal cutting blade surface, where the protective layer completely covers the cutting blade surface.

[0016] Furthermore, the cutting process of the glass substrate includes the following steps: The gantry three-coordinate system and the cutting mechanism work together to drive the cutter wheel to cut on the glass substrate according to the preset product parameters.

[0017] The cutter wheel cuts the protective layer and the glass substrate according to the preset product parameters and fits the edge of the product shape.

[0018] The cutting surface of the cut product is completely covered by the protective layer.

[0019] Furthermore, the cutting mechanism includes a lifting module, and a cutter wheel is movably connected to the bottom output end of the lifting module. The sawtooth angle of the cutter wheel is between 100°-120°, and the number of teeth of the cutter wheel is between 460-520.

[0020] The lifting module configured in the cutting mechanism can be equipped with optional electric push rods, cylinders and motor linear modules, etc., which can provide a mechanical structure with linear movement direction.

[0021] The improved cutter wheel structure can complete the cutting operations of the peelable adhesive and the glass substrate at the same time. Compared with the blank exposed area that needs to be reserved on the glass substrate when printing the traditional peelable adhesive, the generation of the blank exposed area will cause processing marks such as oil printing and dirt to appear in the area corresponding to the blank exposed area on the glass substrate.

[0022] 3. Beneficial effects: Compared with the prior art, the technical solution provided by the present invention has the following beneficial effects: The present invention provides a new touch screen protective adhesive cutting process. The redesigned cutter wheel is adjusted in sawtooth angle and number of teeth, which brings a new process technology for peelable adhesive cutting and molding, meets the simultaneous cutting operation requirements of the peelable adhesive and glass substrate on the blank substrate, can effectively solve customer complaints (difficulty in tearing the film, dirt, fingerprints, residue, abnormal imprints, etc.) and increase product strength, and saves the cost of silk screen design and production; The parts not involved in the device are the same as those in the prior art or can be implemented by using the prior art.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which the present invention belongs; the terms used in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention; the term "and / or" used herein includes any and all combinations of one or more related listed items.

[0028] See attached Figure 1-5 The present invention provides a novel touch screen protective adhesive cutting process, comprising the following steps: The protective layer covers the glass substrate, and the protective layer forms a blank substrate after drying.

[0029] The blank substrate is fixed on the workbench 4 , and the linear module 3 moves the workbench 4 to the bottom of the gantry three-coordinate system 1 .

[0030] The gantry three-coordinate machine 1 moves the cutting mechanism 2 to move the cutter wheel 22 to the top of the blank substrate. The cutting mechanism 2 changes the pressure of the cutter wheel 22 on the blank substrate through the preset lifting module 21.

[0031] The cutter wheel 22 is used to cut the blank substrate according to different preset product specifications.

[0032] In this embodiment, the top of the glass substrate is divided into a cutting surface, and the entire cutting surface is covered with a protective layer, which is a peelable adhesive.

[0033] The design of the protective layer is preferably a peelable adhesive in the present application, and the peelable adhesive is printed on the glass substrate to form a blank substrate.

[0034] In the present solution, the number of teeth and the angle of the cutter wheel 2 are redesigned so that the glass substrate and the peelable adhesive can be cut at the same time, and there is no peeling of the peelable adhesive and cracking of the glass substrate at the edge of the cut blank substrate. Therefore, there is no need to refer to the operation of designing a screen and reserving a blank exposed area in the peelable adhesive printing work before cutting the traditional blank substrate, which effectively saves the printing and production costs of the peelable adhesive screen and the workload of screen design and drawing, simplifies the process in the entire production link of the blank substrate, and improves the production efficiency of the blank substrate from the glass substrate to the finished product stage after cutting.

[0035] At the same time, the glass substrate can be fully covered by the peelable adhesive, and the edges of the cut products are protected. Therefore, the strength of the products cut by the redesigned cutter wheel 22 in the four-point bending test is significantly stronger than that of the products in the prior art that require reserved blank exposed areas.

[0036] In this embodiment, the protective layer construction process of the glass substrate includes the following steps: The cutting blade surface of the glass substrate is cleaned.

[0037] Place the cleaned glass substrate and adjust the cutting blade surface to be level.

[0038] The protective layer is covered on the horizontal cutting blade surface, where the protective layer completely covers the cutting blade surface.

[0039] In this embodiment, the cutting process of the glass substrate includes the following steps: The gantry three-coordinate system 1 and the cutting mechanism 2 cooperate to drive the cutter wheel 22 to cut on the glass substrate according to preset product parameters.

[0040] The cutter wheel 22 cuts the protective layer and the glass substrate according to preset product parameters and in accordance with the product's outer shape edge.

[0041] The cutting surface of the cut product is completely covered by the protective layer.

[0042] In this embodiment, the cutting mechanism 2 includes a lifting module 21, and the bottom output end of the lifting module 21 is movably connected to a cutter wheel 22, the sawtooth angle of the cutter wheel 22 is between 100°-120°, and the number of teeth of the cutter wheel 22 is between 460-520.

[0043] The redesigned cutter wheel 22 is adjusted in sawtooth angle and number of teeth, bringing a new process technology for peelable adhesive cutting and forming, meeting the needs of simultaneous cutting of peelable adhesive and glass substrate on blank substrate, and can effectively solve customer complaints such as difficulty in tearing film, dirt, fingerprints, residue, abnormal imprints, etc., increase product strength, and save costs such as silk screen screen design and production.

[0044] The peelable adhesive covers the entire surface of the glass substrate, reducing processing traces such as dirt on the glass substrate. The edge of the peelable adhesive in the cut product is close to the edge of the glass substrate, which is convenient for users to carry out subsequent peelable adhesive removal operations. Compared with existing products with reserved blank exposed areas, users do not need to use tools to scrape the surface of the glass substrate to remove the peelable adhesive, thereby improving the product yield of the glass substrate after cutting.

[0045] The above-described embodiments only express a certain implementation mode of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the patent scope of the present invention. It should be pointed out that, for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the present invention, which all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention shall be based on the attached claims.
