Description

Technical Field

[0001] The present invention relates to the technical field of glass processing grinding heads and processes, and in particular to a novel glass deep processing integrated grinding head and a processing technology. Background Art

[0002] With the rapid development of science and technology, especially the popularity of consumer electronic products, the demand for materials such as optical glass, sapphire and quartz glass with curved edge design is increasing. These materials are widely used in smartphone screens, tablets, smart watches and other high-end display devices. In order to meet the requirements of these products for beauty and touch, complex processing technology is usually required.

[0003] The traditional processing method mainly includes the following steps:

[0004] CNC roughing: First, use a CNC machine to remove most of the excess material to form a rough shape;

[0005] Finishing: Next, more detailed processing is performed to ensure that the edges are smooth and meet the design requirements;

[0006] Polishing: Remove the fork with multiple glass workpieces from the CNC machine and transfer it to the polishing department, or collect the glass workpieces and transfer them to a special polishing equipment for surface polishing to improve transparency and glossiness;

[0007] Some products require additional steps such as hole opening and hole finishing.

[0008] There are several significant problems with this step-by-step processing method:

[0009] Inefficiency: Multiple tool changes and workpiece transfers increase overall production time;

[0010] High cost: Additional polishing equipment and its maintenance costs lead to higher total costs;

[0011] Difficulty in quality control: Moving workpieces between different devices may cause positioning errors, affecting the consistency of final product quality;

[0012] Complex operation: Frequent loading and unloading of workpieces and adjustment of equipment settings increase the risk of human error;

[0013] Furthermore, since each tool change or transfer requires recalibration, this is not only time-consuming but can also result in a loss of precision. Especially when processing small, high-precision parts, any slight positional deviation can result in unacceptable quality issues. Therefore, it is particularly important to develop a technology that can continuously complete all necessary processes on a single device. Summary of the invention

[0014] In order to overcome the above-mentioned defects, the present invention provides a new type of one-piece grinding head and processing technology for deep processing of glass, which can continuously complete processes such as roughing, fine arc edge trimming and final polishing on a single CNC machine, thereby simplifying the process flow, reducing production costs, and improving product quality consistency.

[0015] The present invention discloses a novel one-piece grinding head for deep processing of glass, comprising a tool handle, a polishing wheel, and a processing section. The polishing wheel is fixedly mounted on one end of the tool handle, the processing section is located on the outside of the polishing wheel, a curved polishing portion is formed at the connection between the polishing wheel and the processing section, a straight polishing portion is formed on the circumference of the polishing wheel, and the processing section comprises an outer shape roughening portion, an outer shape finishing portion, a tool tip, and a hole finishing portion.

[0016] Further describing the above scheme, the processing sections are, from the polishing wheel back to the tool handle, the shape roughening section, the shape finishing section, the hole finishing section, and the tool tip.

[0017] Furthermore, an arc-pressing finishing portion is provided between the shape finishing portion and the hole finishing portion.

[0018] According to one embodiment of the present application, the processing section is, in sequence, an outer shape finishing portion, an outer shape roughening portion, a hole finishing portion, and a tool tip from the polishing wheel toward the tool handle, and an arc enlarging finishing portion is provided between the outer shape finishing portion and the arc polishing portion, and a hole enlarging roughening portion and an arc enlarging roughening portion are provided between the hole finishing portion and the outer shape roughening portion.

[0019] Furthermore, the number of machining grooves of the shape finishing portion is greater than 2, and the machining grooves include a working area and a chip removal area, and the chip removal area is close to one side of the tool tip.

[0020] Further describing the above scheme, the processing section fixes the diamond particles on the surface by electroplating.

[0021] Furthermore, the tool handle and the processing section are made of high-strength steel or hard alloy material, and the polishing wheel is made of polyurethane or resin material.

[0022] The present invention also provides a novel glass processing technology, including the novel glass deep processing integrated grinding head described above, including the following processing steps:

[0023] S1: Roughing: First, use the roughing part to remove unnecessary materials to form the basic shape of the product. This step is mainly to quickly remove excess materials and lay the foundation for subsequent finishing work;

[0024] S2: Shape finishing: Then use the shape finishing department to finely trim the initially formed product to ensure that the edges are smooth and burr-free and achieve the required dimensional accuracy;

[0025] S3: Pressing and roughing: For products that require curvature arc edges, use the pressing and roughing part to process these areas. This step is mainly for the initial shaping of the arc surface part to prepare for subsequent fine finishing. Some products do not need to be pressed and roughed;

[0026] S4: Arc pressing and finishing: The arc pressing and finishing department is then used to perform fine processing on the roughened area to ensure the smoothness and flatness of the arc surface to meet the design requirements;

[0027] S5: Drilling: Use the tool tip to drill holes at the specified location. This step requires extremely high positioning accuracy and control capabilities to ensure that the hole position is accurate;

[0028] S6: Hole expansion and roughing: In order to further expand the existing hole diameter for subsequent fine finishing work, the hole expansion and roughing part will be used to quickly increase the hole size;

[0029] S7: Hole finishing: The hole finishing section is used to adjust the size and shape of the hole to ensure that the hole edge is smooth and meets the final design standards;

[0030] S8: Curved surface polishing: Use the curved surface polishing part of the polishing wheel to polish all curved surfaces. This step can significantly improve the transparency and glossiness of the curved surface, making it look clearer and brighter.

[0031] S9: Straight polishing: Finally, use the straight polishing part of the polishing wheel to polish the non-curved part. This process also improves the quality of the entire product surface and ensures the consistency and beauty of the overall appearance.

[0032] Through the above steps, a new type of glass deep processing integrated grinding head and processing technology can realize the whole process from raw materials to finished products on a single CNC machine, which not only improves production efficiency but also ensures the consistency of product quality. This method reduces manual intervention in the intermediate links, reduces the complexity of operation, and saves time and cost.

[0033] During the aforementioned processing, it is also necessary to spray polishing liquid or water or a combination of polishing powder and water or polishing liquid and water to reduce friction heat and improve the polishing effect.

[0034] Furthermore, for step S2, since the workload of the shape finishing section is relatively large, the number of processing grooves of the shape finishing section is greater than 2. After each processing groove is processed to a specified time, the next processing groove is switched, and the entire grinding head will be scrapped when it reaches the predetermined time.

[0035] Compared with the prior art, the novel glass deep processing integrated grinding head and processing technology of the present invention can effectively solve the various drawbacks existing in the above-mentioned traditional processing flow and bring the following significant advantages:

[0036] Simplify the process flow: By integrating the functions of roughing, finishing, drilling, expanding, finishing, arc pressing and polishing in one design, the number of tool changes and the time required for switching between equipment during the processing can be greatly reduced, thereby greatly improving production efficiency.

[0037] Reduce production costs: No need to purchase additional polishing equipment, which also reduces downtime and material waste caused by frequent tool changes, which can help companies save a lot of money in the long run.

[0038] Improve product quality consistency: The entire processing process is completed in a fixed working environment, avoiding positioning errors caused by workpiece handling and ensuring high consistency in finished product dimensional accuracy and surface quality.

[0039] Enhanced flexibility: For glass products of different specifications, the corresponding grinding heads can be simply replaced to adapt to various processing needs, making the production line more flexible and changeable.

[0040] Improved safety: Reduced manual intervention reduces the risk of operator injury and improves the safety of the working environment.

[0041] In short, this new type of glass deep processing one-piece grinding head and processing technology can not only greatly optimize the existing production process, but also create greater economic benefits and social value for the enterprise. It is an important innovative achievement in the field of glass processing in the future. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0051] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0052] To make the technical solutions and advantages of the present invention more clear, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0053] Example 1

[0054] See also Figure 1-Figure 3 As shown, this embodiment discloses a novel one-piece grinding head for deep processing of glass, comprising a handle 1, a polishing wheel 2, and a processing section. The polishing wheel 2 is fixedly mounted on one end of the handle 1, and the processing section is located on the outside of the polishing wheel 2. The connection between the polishing wheel 2 and the processing section forms an arc polishing portion 22, and the peripheral surface of the polishing wheel 2 forms a straight polishing portion 21. The processing section comprises an outer shape roughening portion 3, an outer shape finishing portion 4, a tool tip 7, and a hole finishing portion 6. The processing section is sequentially composed of an outer shape roughening portion 3, an outer shape finishing portion 4, an arc pressure finishing portion 5, a hole finishing portion 6, and a tool tip 7 from the polishing wheel 2 to the direction away from the handle 1. Figure 3As shown, the number of machining grooves of the shape finishing part 4 is 3, and the machining grooves include a working area 41 and a chip removal area 42, and the chip removal area 42 is close to the side of the tool tip 7. When performing shape finishing, the chip removal area 42 can quickly discharge slag and liquid to improve the machining accuracy and machining effect. It should be noted that different numbers of machining grooves can be selected according to the processed products. Generally, products with more rough areas of the shape need to be equipped with grinding heads with more machining grooves to avoid replacing the grinding heads due to excessive wear of the shape finishing part 4 during the machining process. In addition to the variable number of machining grooves, the shape finishing part 4 can also adjust the spacing and width of the machining grooves to meet the processing requirements of the product.

[0055] In this embodiment, the handle 1 and the processing section are made of high-strength steel or hard alloy material to ensure sufficient rigidity and strength. Diamond particles are fixed on the surface of the processing section by electroplating, and the polishing wheel 2 is made of polyurethane or resin material.

[0056] Example 2

[0057] See also Figure 4 , Figure 5 As shown, on the basis of Example 1, the processing section is adjusted. The processing section is sequentially composed of the shape finishing portion 4, the shape roughening portion 3, the hole finishing portion 6, and the tool tip 7 from the polishing wheel 2 in the direction away from the tool handle 1, and the arc-pressing finishing portion 5 is arranged between the shape finishing portion 4 and the arc polishing portion 22, and the hole-expanding roughening portion 8 and the arc-pressing roughening portion 51 are arranged between the hole finishing portion 6 and the shape roughening portion 3.

[0058] The present invention also discloses a novel glass processing process, including the novel glass deep processing integrated grinding head provided by the above-mentioned embodiment 2, including the following processing steps:

[0059] S1: roughing: First, use the roughing part 3 to remove unnecessary materials to form the basic shape of the product. This step is mainly to quickly remove excess materials and lay the foundation for subsequent finishing work;

[0060] S2: Shape finishing: Then, the shape finishing section 4 is used to perform fine finishing on the initially formed product to ensure that the edges are smooth and free of burrs and that the required dimensional accuracy is achieved;

[0061] S3: Pressing and roughing: For products that require curved edges, use the pressing and roughing section 51 to process these areas. This step is mainly for preliminary shaping of the curved surface to prepare for subsequent fine finishing. Some products do not need to be pressed and roughed.

[0062] S4: Arc pressing and finishing: Then the arc pressing and finishing unit 5 is used to perform fine processing on the roughened area to ensure the smoothness and flatness of the arc surface to meet the design requirements;

[0063] S5: drilling: using the tool tip 7 to drill holes at the specified position. This step requires extremely high positioning accuracy and control capabilities to ensure that the hole position is accurate;

[0064] S6: Hole expansion and roughing: In order to further expand the existing hole diameter for subsequent fine finishing work, the hole expansion and roughing part 8 will be used to quickly increase the hole size;

[0065] S7: Hole finishing: The hole finishing section 6 is used to finally adjust the size and shape of the hole to ensure that the hole edge is smooth and meets the final design standards;

[0066] S8: Arc polishing: Use the arc polishing part 22 in the polishing wheel 2 to polish all the arc surfaces. This step can significantly improve the transparency and glossiness of the arc surface, making it look clearer and brighter.

[0067] S9: Straight body polishing: Finally, the straight body polishing part 21 in the polishing wheel 2 is used to polish the non-arc surface part. This process also improves the quality of the entire product surface and ensures the consistency and aesthetics of the overall appearance.

[0068] During the processing, it is also necessary to spray polishing liquid or water or a combination of polishing powder and water or polishing liquid and water to reduce friction heat and improve the polishing effect.

[0069] Through the above steps, the use of grinding heads and processing technology can realize the whole process from raw materials to finished products on a single CNC machine, which not only improves production efficiency but also ensures the consistency of product quality. This method reduces manual intervention in the intermediate links, reduces the complexity of operation, and saves time and cost.
