[0029] See Figure 1 and Figure 2 According to a first aspect of the present disclosure, a grinding head tooling is provided, including a grinding head body 1, a first press-in part 2, and a second press-in part 3. The first press-in part 2 is arranged at the end of the grinding head body 1 facing the workpiece for drilling and / or reaming. The second press-in part 3 is arranged on the grinding head body 1 and on the side of the first press-in part away from the workpiece for grinding the hole. The grinding head body 1 serves as the basic part of the entire tooling, bears other components, and is connected to the processing equipment. The first press-in part 2 efficiently forms the required holes or other shapes on the workpiece, and the second press-in part 3 performs finish machining on the surface of the hole to ensure the dimensional accuracy and flatness of the hole.

[0030] The grinding head tooling provided by the present disclosure can be used to process any kind of workpiece, such as: plates, display screens, and lenses. Hereinafter, photovoltaic glass will be used as the workpiece for detailed description.

[0031] When using this grinding head tooling to process photovoltaic glass, first, the first press-in part 2 completes the cutting of the photovoltaic glass to form the required holes. Then, without changing the tool, the second press-in part 3 can perform surface finish machining on the formed holes to achieve the required dimensional accuracy and flatness. After the entire process is completed, the grinding head retracts, thereby realizing the efficient drilling and finish machining grinding of the photovoltaic glass, which is beneficial to improving work efficiency.

[0032] In some embodiments, the first press-in part 2 includes a cutting plane 2-1 and a cutting peripheral surface 2-2. The cutting plane 2-1 is the end face of the grinding head body 1 facing the workpiece. The cutting peripheral surface 2-2 is located on the periphery of the cutting plane 2-1. A number of convex points are provided on the cutting plane 2-1. The cutting plane 2-1 is located at the end face of the grinding head body 1 facing the workpiece and is the first part where the grinding head contacts the photovoltaic glass. The cutting peripheral surface 2-2 is located on the periphery of the cutting plane 2-1 and is used to assist in forming the side wall of the hole. The convex points are provided on the cutting plane 2-1 and are the key parts for cutting the photovoltaic glass, and are used to provide effective cutting force during the drilling process.

[0033] In addition, it should be noted that the convex points are made of high-strength materials such as cemented carbide or diamond, which have wear resistance. Their shapes and distributions can be optimized according to different materials and processing requirements to improve cutting efficiency and stability. A coolant circulation channel is provided inside the grinding head body 1 to ensure that the coolant circulates in the circulation channel during the processing, improving the cooling effect and extending the tool life.

[0034] In some embodiments, at least one guiding groove 4 is provided on the cutting plane 2-1. The guiding groove 4 can be arranged at the center position of the cutting plane or distributed in different regions of the cutting plane. The specific position can be determined according to the actual processing requirements. The guiding groove 4 can be linear, arc-shaped or other suitable shapes to adapt to different processing paths and requirements. The guiding groove 4 can help the first pressing-in part 2 move better along the predetermined path, reduce deviation and improve processing accuracy. In addition, the guiding groove 4 can also assist the flow of the coolant or the chips of the photovoltaic glass, ensuring that the coolant can effectively cover the cutting area and the residual chips do not affect the cutting effect. Exemplarily, referring to Figure 2 , the guiding groove 4 can be set as two intersecting linear grooves located on the cutting plane 2-1.

[0035] In some embodiments, a first chamfer 2-3 is formed at the adjacent position of the cutting plane 2-1 and the cutting peripheral surface 2-2. The first chamfer 2-3 can be a rounded corner, an inclined angle or other suitable shapes. The specific shape can be determined according to the actual processing requirements. By setting the first chamfer 2-3, the stress generated during the cutting process of the first pressing-in part 2 can be effectively dispersed, reducing the risk of the tool being damaged due to stress concentration. The first chamfer 2-3 can make the cutting process of the first pressing-in part 2 smoother, reduce the accumulation of materials during the cutting process and improve the cutting efficiency.

[0036] In some embodiments, the cross-sectional area of the second pressing-in part 3 gradually decreases along the length direction of the grinding head body 1 from its connection with the first pressing-in part 2. The gradually decreasing cross-sectional area can reduce the resistance encountered during the finishing process, enabling the second pressing-in part 3 to perform finishing in the hole. Since the cross-sectional area gradually decreases, the stress received by the second pressing-in part 3 when entering the hole will also gradually decrease, thereby reducing the risk of wear and damage of the second pressing-in part 3.

[0037] In some embodiments, a second chamfer 5 is provided at the adjacent position of the first pressing-in part 2 and the second pressing-in part 3. The second chamfer 5 can be a rounded corner, an inclined angle or other suitable shapes. The specific shape can be determined according to the actual processing requirements. By setting the second chamfer 5, the stress generated at the connection of the first pressing-in part 2 and the second pressing-in part 3 can be effectively dispersed, reducing the risk of the grinding head being damaged due to stress concentration. The second chamfer 5 can make the transition between the first pressing-in part 2 and the second pressing-in part 3 smoother, reduce the accumulation of materials generated during the switching process and improve the cutting efficiency.

[0038] In some embodiments, a forming tool 6 is further provided on the grinding head body 1. The forming tool 6 is located on the side of the second pressing portion 3 away from the workpiece, is provided on the grinding head body, and is located on the side of the second pressing portion away from the workpiece, and is used for chamfering and leveling the connection between the hole and the surface of the workpiece, removing fine burrs or unevenness, which is beneficial to improving the quality of the photovoltaic glass.

[0039] In some embodiments, the forming tool 6 is provided with a conical surface 6-1, and the conical surface 6-1 faces the second pressing portion 3. The conical surface 6-1 can reduce the resistance when the forming tool 6 enters the hole, making it easier for the grinding head body 1 to enter and perform scraping and leveling.

[0040] In some embodiments, the forming tool 6 and the grinding head body 1 are integrally formed, and the second pressing portion 3 and the grinding head body 1 are integrally formed. The integrally formed design eliminates the weak links at the joints, improves the overall strength and durability of the grinding head. The integral forming reduces the tolerance accumulation that may occur during the assembly process, which is beneficial to improving the machining accuracy of the grinding head. The integral forming reduces the number of connecting parts, reducing the failure of the grinding head caused by the loosening or breakage of the connecting parts.

[0041] The second aspect of the present disclosure provides a photovoltaic glass processing device, including the grinding head tooling provided in any of the above embodiments. This photovoltaic glass processing device can simplify the processing process, complete the punching and finish grinding of the photovoltaic glass without replacing the tool, shorten the operation time, and is beneficial to improving work efficiency.

[0042] To better understand the technical solution of the present disclosure, the following is described in combination with relatively preferred technical features.

[0043] Participate Figure 1 And Figure 2, the present disclosure provides a grinding head tooling, which includes a grinding head main body 1, a first press-in part 2, a second press-in part 3 and a forming scraper 6. The first press-in part 2 is arranged at the end of the grinding head main body 1 facing the workpiece for drilling and reaming. The second press-in part 3 is arranged on the grinding head main body 1 and on the side of the first press-in part away from the workpiece for grinding the hole. The forming scraper 6 is located on the side of the second press-in part 3 away from the workpiece. The forming scraper 6 is provided with a conical surface 6-1, and the conical surface 6-1 faces the second press-in part 3. The first press-in part 2 includes a cutting plane 2-1 and a cutting peripheral surface 2-2. The cutting plane 2-1 is the end surface of the grinding head main body 1 facing the workpiece. The cutting peripheral surface 2-2 is located on the periphery of the cutting plane 2-1. A number of convex points are provided on the cutting plane 2-1. At least one guiding groove 4 is provided on the cutting plane 2-1. A first chamfer 2-3 is formed at the adjacent position of the cutting plane 2-1 and the cutting peripheral surface 2-2. The cross-sectional area of the second press-in part 3 gradually decreases along the length direction of the grinding head main body 1 from its connection with the first press-in part 2. A second chamfer 5 is provided at the adjacent position of the first press-in part 2 and the second press-in part 3. The forming scraper 6 and the grinding head main body 1 are integrally formed. The second press-in part 3 and the grinding head main body 1 are integrally formed.

[0044] The processing steps for the hole in the above solution are as follows. When using this grinding head tooling to process photovoltaic glass, the first press-in part 2 first contacts the surface of the photovoltaic glass. The convex points on the cutting plane 2-1 play a cutting role and cooperate with the cutting peripheral surface 2-2 to complete the formation of the hole. Subsequently, the second press-in part 3 continues to grind the inner surface of the hole. Its design with a gradually decreasing cross-sectional area makes the finishing process smoother and improves the smoothness and flatness of the hole wall. The design of the second chamfer 5 makes the transition between the first press-in part 2 and the second press-in part 3 smoother, reduces stress concentration, and improves the processing accuracy. Finally, the forming scraper performs the final scraping and leveling treatment on the hole wall. The conical surface 6-1 further improves the scraping effect and flatness. After the whole process is completed, the grinding head retracts the tool, and the whole process from drilling to finishing and then to the final scraping and chamfering can be completed without changing the tool, which is beneficial to improving the production efficiency.
