[0034] The following is a clear and detailed description of the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only 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.

[0035] See also Figures 1 to 16 The present invention provides a mixed edge grinding mechanism, including a connecting plate 1, on which are arranged at least one flat grinding unit 2, at least one film removal unit 3, at least one upper 45-degree edge grinding unit 4 and at least one lower 45-degree edge grinding unit 5; the flat grinding unit 2 is used to grind the outer side surface of the side edge of the glass 10; the film removal unit 3 is used to remove the protective film on the glass 10; the upper 45-degree edge grinding unit 4 is used to chamfer the top of the side edge of the glass 10 at 45 degrees; the lower 45-degree edge grinding unit 5 is used to chamfer the bottom of the side edge of the glass 10 at 45 degrees.

[0036] In an embodiment of the present invention, the connecting plate 1 is mounted on an edge grinding device, and a pushing or sliding device may be provided on the edge grinding device, so that each functional device on the connecting plate 1 is close to the glass 10 plate, and then the side edge of the glass 10 plate is processed. Specifically, the functional device on the connecting plate 1 has at least one flat grinding unit 2, at least one film removal unit 3, at least one upper 45-degree edge grinding unit 4 and at least one lower 45-degree edge grinding unit 5, and the specific number can be set according to the material of the glass 10 and the needs of the production process. In this embodiment, the flat grinding unit 2 is used to process the vertical surface of the side edge of the glass 10 to improve the flatness of the side surface of the glass 10 plate. In the process of production, transportation, storage and installation of the glass 10, in order to protect the surface from being scratched, a protective film is usually provided on the surface. The protective film can play an isolating role to prevent sharp objects, tools or other hard objects from directly rubbing against the surface of the glass 10, thereby avoiding scratches. Before processing, it is necessary to remove the protective film of the processing area first, so as to avoid the depth of the edge grinding being inaccurate due to the presence of the protective film, which affects the accuracy of the final size and shape of the glass 10. To this end, the present embodiment is provided with a film removal unit 3, which acts on the processing area of ​​the glass 10 to remove the protective film in the area. The upper 45-degree edge grinding unit 4 and the lower 45-degree edge grinding unit 5 act on the top and bottom of the glass 10 respectively to perform a 45-degree chamfering operation on the side of the glass 10.

Compared with using multiple separate devices to perform flat grinding, film removal, chamfering and other operations respectively, the multifunctional integrated structure of the mixed edge grinding mechanism of this embodiment can effectively reduce the floor space occupied by the edge grinding equipment, make the layout of the glass 10 production line more compact and reasonable, and help improve space utilization. The upper 45-degree edge grinding unit 4 and the lower 45-degree edge grinding unit 5 are integrated on the connecting plate 1 and work together, and can accurately control the chamfer size of the top and bottom of the glass 10. The top and bottom of the side of the glass 10 can be accurately chamfered at 45 degrees to ensure the consistency of the chamfer angle, overcome the problem that traditional equipment is prone to deviation and poor consistency when processing at different stations, and can well meet the high-precision processing requirements.

[0045] In this embodiment, please refer to Figure 1 ,from Figure 1 It can be seen that the first lower 45-degree edge grinding unit, the second lower 45-degree edge grinding unit, the first upper 45-degree edge grinding unit, the second upper 45-degree edge grinding unit, the film removal unit, the first flat grinding unit, the second flat grinding unit, the third flat grinding unit, the fourth flat grinding unit and the fifth flat grinding unit are arranged in sequence. The following is a detailed description of each unit in combination with the glass processing process:

[0046] When the entire mixed edge grinding mechanism is close to the glass plate, the lower chamfer wheel of the first lower 45-degree edge grinding unit performs a rough grinding of the lower edge of the glass at a 45-degree angle. The mesh number of the lower chamfer wheel in this process is small, and the surface it grinds is relatively rough. It is suitable for the rough grinding stage and is used to quickly trim the glass edge to ensure that the excess part of the glass is removed efficiently. After the first lower 45-degree edge grinding, the glass enters the second lower 45-degree edge grinding unit. This unit further fine-grinds the lower edge of the glass. Compared with the first lower 45-degree edge grinding unit, the lower chamfer wheel used in the second lower 45-degree edge grinding unit has a higher mesh number, the purpose is to further refine the bevel surface, reduce the surface roughness, and improve the flatness and finish of the bevel. In this process, the lower chamfer wheel with a higher mesh number will more accurately remove the tiny flaws and uneven parts of the glass edge, making the bevel angle of the lower edge of the glass more accurate and the surface smoother, meeting higher processing accuracy requirements.

[0047] After completing the two 45-degree edgings of the lower edge, the glass is transported to the first upper 45-degree edging unit. The working principle of this unit is similar to that of the first lower 45-degree edging unit, except that the upper chamfering wheel with a lower mesh count grinds the upper edge of the glass at a 45-degree angle. After the first upper 45-degree edging is completed, the glass enters the second upper 45-degree edging unit. Like the second edging process of the lower edge, this unit fine-grinds the upper edge of the glass. By using a higher mesh upper chamfering wheel, the upper edge bevel is finely trimmed to further improve the surface quality of the upper edge bevel, so that its flatness, finish and angle accuracy all reach higher standards to meet the design and quality requirements of the product.

[0048] During the glass edge grinding process, some protective film or other impurities may remain on the glass surface. The function of the film removal unit is to remove these materials.

[0049] After the film is removed, the glass enters the first flat grinding unit, which performs rough grinding on the edge of the glass. The unit uses a grinding wheel with a lower mesh to perform rough processing. After the first flat grinding unit is completed, the glass enters the second flat grinding unit. This unit uses a grinding wheel with a slightly higher mesh to further rough grind the edge of the glass. After the second flat grinding unit, the glass enters the third flat grinding unit. The third flat grinding unit continues to use a grinding wheel with a higher mesh to perform more fine grinding on the edge of the glass. The fourth flat grinding unit uses a grinding wheel with a higher mesh to perform deep fine grinding on the edge of the glass. The grinding wheel used in this unit has a very fine particle size and can perform extremely fine grinding on the edge of the glass. The fifth flat grinding unit is the last flat grinding process of the entire edge grinding process. It is mainly used to perform the final polishing of the edge of the glass. By using a grinding wheel with a higher mesh to grind, the edge of the glass reaches a nearly mirror-like finish, while ensuring that the flatness and dimensional accuracy of the edge meet the design requirements, meeting the stringent requirements of high-end products for the quality of the glass edge.

[0050] Preferably, the flat grinding unit 2, the film removal unit 3, the upper 45-degree edge grinding unit 4 and the lower 45-degree edge grinding unit 5 are respectively connected to the connecting plate 1 through a sliding adjustment mechanism; the sliding adjustment mechanism includes a pair of linear slides, a propulsion cylinder and a propulsion seat; at least two slider seats are provided on the linear slide, the linear slide and the propulsion cylinder are respectively connected to the connecting plate 1, and the propulsion seat and the slider seat are respectively installed on the top of the corresponding flat grinding unit 2, the film removal unit 3, the upper 45-degree edge grinding unit 4 or the lower 45-degree edge grinding unit 5; the piston rod of the propulsion cylinder is connected to the propulsion seat and drives the propulsion seat to move. In this embodiment, the flat grinding unit 2, the film removal unit 3, the upper 45-degree edge grinding unit 4 and the lower 45-degree edge grinding unit 5 under the connecting plate 1 are respectively connected through a sliding adjustment mechanism, so that each unit can slide freely and can move forward and backward freely according to actual production needs.
