Description

Technical Field

[0001] The present invention relates to the technical field of glass cover plate processing, and in particular to a method for manufacturing a glass screen cover plate. Background Art

[0002] With the development of science and technology, smart electronic devices such as mobile phones and tablet computers can be seen everywhere in life. Most of these devices use touch screens as tools for collecting and identifying information. As an important part of the touch screen, the appearance parts can not only protect the internal structure of the product, but also resist scratches and stains. At the same time, they can be printed with different colors and patterns, and then matched with corresponding surface treatment technologies to achieve the purpose of decorating and beautifying the product. For this purpose, a method for making a glass screen cover is proposed. Summary of the invention

[0003] In order to solve the technical problem raised in the background technology, the present invention provides a method for manufacturing a glass screen cover.

[0004] The present invention is implemented by the following technical solution: A method for manufacturing a glass screen cover comprises the following steps:

[0005] Step 1: Plate a hard layer on the upper and lower surfaces of the original large glass to protect the glass cover;

[0006] Step 2: Cut the large piece into several small pieces as required, which can achieve special-shaped cutting;

[0007] Step 3: Profiling: CNC grinding the shaped product twice;

[0008] Step 4: Place paper between two adjacent lower cover plates after profiling, use an edge polishing machine to perform edge polishing, and add a hard layer as a protective layer;

[0009] Step 5: Grind the upper and lower surfaces of the cover plate after edge polishing to remove the hardened layer and micro cracks on the upper and lower surfaces;

[0010] Step 6: Chemically toughen the cover plate processed in step 5 to increase its mechanical strength;

[0011] Step 7: Print patterns and main ink on the surface of the cover plate, and coat anti-fingerprint oil;

[0012] Step 8: Finished product inspection.

[0013] As a further improvement of the above solution, the edge polishing machine includes a positioning fixture for stacking and fixing the partition plates. The positioning fixture includes a bearing plate and four groups of positioning mechanisms, and the four groups of positioning mechanisms are arranged in a rectangular shape on the bearing plate. The positioning mechanism includes an auxiliary clamping rod and a main clamping rod, and the main clamping rod is arranged in the height direction of a plurality of stacked cover plates. The auxiliary clamping rod and the main clamping rod are arranged in parallel and can rotate relative to each other. The main clamping rod and the bearing plate are connected through a connecting mechanism. Through the above structure, when polishing one side of the cover plate, the other three sides can be fixed, so that the edge polishing structure is better and the product processing quality is improved.

[0014] As a further improvement of the above solution, the connecting mechanism includes a first connecting plate and a second connecting plate. The first connecting plate and the second connecting plate are connected through a distance adjusting unit. The main clamping rod is connected to the first connecting plate, and the second connecting plate is rotatably connected to the bearing plate through a rotating shaft. A driving component is further arranged on the bearing plate to drive the rotating shafts in each connecting mechanism to rotate. The distance between the main clamping rod and the cover plate to be edge polished can be conveniently adjusted through the distance adjusting unit, so as to clamp and fix it, keep it stable during polishing, and improve the product processing quality.

[0015] As a further improvement of the above solution, the distance adjusting unit includes a connecting rod, a fixing frame, a screw rod and a power component for driving the screw rod to rotate. Among them, one end of the connecting rod is connected to the first connecting plate, the other end of the connecting rod is connected to the fixing frame, a threaded hole in spiral fit with the screw rod is formed on the fixing frame, and the power component is arranged on the second connecting plate. Using the screw rod to drive the distance to change, the adjustment speed is slower and the accuracy is higher, avoiding damaging the product.

[0016] As a further improvement of the above solution, the second connecting plate is provided with a communicating first mounting hole and a second mounting hole, and a part of the screw rod is located in the second mounting hole. A circular dial is rotatably mounted in the first mounting hole. The dial and the screw rod are coaxially fixed. A toothed ring is sleeved on the outer surface of the dial. The power component includes a micro motor arranged on the second connecting plate and a gear connected to the output shaft of the micro motor, and the gear meshes with the toothed ring. The micro motor is externally connected to a power supply and drives the dial to rotate while driving the screw rod to rotate.

[0017] As a further improvement of the above solution, the driving component includes a long strip-shaped central electromagnet arranged at the center of the bearing plate, and magnetic movable plates arranged on opposite sides of the central electromagnet. A driving rod is fixed on the side of the two magnetic movable plates away from the central electromagnet; alternating current is passed through the central electromagnet, so that its magnetism can change, and thus the magnetic movable plates can be attracted or repelled, so that the driving rod can move back and forth in its length direction.

[0018] A drive gear is installed on the outer side of the rotating shaft on the second connecting plate. The drive rod passes through between two drive gears on the same side, and a rack meshing with the drive gear is arranged on the outer side of the drive rod. When the drive rod moves, it can drive the drive gear to rotate, thereby driving the position of the main clamping rod on the first connecting plate to change. In this way, under the action of the distance adjustment unit, the cover plate can be clamped on different sides to facilitate grinding each side of the cover plate using this jig.

[0019] As a further improvement of the above solution, the main clamping rod is a hollow rod, and a rotating rod is movably inserted at one end of the main clamping rod away from the first connecting plate. A rotating plate is installed at the end of the rotating rod, a connecting column is installed at the other end of the rotating plate, and a pressing disc is installed at the end of the connecting column. Through the above structure, the whole can be tightly pressed at the cover plate far from the uppermost part of the bearing plate, so that the positioning is more stable during grinding.

[0020] As a further improvement of the above solution, an electric telescopic rod is arranged inside the main clamping rod, and the output end of the electric telescopic rod is connected to the inner end of the rotating rod. The electric telescopic rod can be used by connecting to an external power supply.

[0021] As a further improvement of the above solution, a rotating ring is movably sleeved on the outer side of the main clamping rod, the outer side of the rotating ring is connected to a connecting rod, and the other end of the connecting rod is connected to an auxiliary clamping rod.

[0022] As a further improvement of the above solution, a rotation driving unit for driving the rotation of the rotating ring is arranged inside the main clamping rod. The rotation driving unit includes a rotation driving motor arranged inside the main clamping rod, a guiding hole opened on the shell of the main clamping rod, and a fixing plate slidably penetrating through the guiding hole. One end of the fixing plate is connected to the rotating ring, and the output end of the rotation driving motor is connected to the other end of the fixing plate. Through the above structure, the auxiliary clamping rod on the main clamping rod can be driven to rotate relatively. When the main clamping rod is tightly attached to one side of the cover plate, the rotation of the auxiliary clamping rod can be used to make it tightly attached to another adjacent side of the cover plate, so as to polish any side of the cover plate according to the grinding needs.

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0024] The manufacturing method proposed by the present invention is to coat a hardening layer on a large substrate glass, which improves the operation efficiency; the laser + water cooling cutting method can achieve special-shaped cutting and improve the profiling operation efficiency at the same time; there is no spacer paper edge grinding between two pieces, which improves the edge grinding lamination efficiency.

[0025] The positioning jig proposed by the present invention can effectively and quickly fix the laminated cover plate, facilitate grinding any side of the cover plate, effectively improve the work efficiency, and improve the product processing quality. Description of the Drawings
