[0002] Optical glass is a glass that can change the direction of light propagation and the relative spectral distribution of ultraviolet, visible or infrared light. For square and hexagonal optical glass flat sheets, the edges are sharp after cutting, so they need to be polished and chamfered to make them blunt. In this way, when the optical glass is cut and installed, it is not easy to damage other parts, and the edges of the optical glass are not easy to crack, ensuring the overall stability of the optical glass. Chamfering equipment is needed when processing glass.

[0003] However, most of the chamfering equipment on the market currently requires manual operation to chamfer the glass.

Manual operation has high requirements for personnel, is prone to errors, and the yield rate of processed products is not high. In addition, the frosted surface of the grinding wheel needs to face the edge of the glass during chamfering, otherwise the edge will tilt to one side of the lens, and the grinding amount of the two adjacent sides where the edge is located is inconsistent, which is prone to deviation, and the size does not meet the requirements, and the precision is low.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 As shown, a preferred embodiment of the utility model proposes a high-precision optical glass beveling machine, which mainly includes a base plate 15, a fixing seat 2, a mounting plate 1, a product placement rack 5, a beveling mechanism, a driving mechanism 4 and other components, wherein two base plates 15 are provided and are distributed in parallel, and slide rails are provided on the two base plates 15, and the two sides of the bottom of the mounting plate 1 are respectively slidably connected to the two slide rails; a rectangular through hole is provided in the middle of the mounting plate 1, so that the grinding wheel 11 in the beveling mechanism can pass through the through hole to contact the edge of the optical glass to perform beveling operation on it.

[0024] Slide rails are provided at both the front and rear ends of the mounting plate 1, and two fixing seats 2 are provided, which are distributed in parallel, and the two ends of the fixing seat 2 are respectively slidably connected with the two slide rails on the mounting plate 1, so that the distance between the two fixing seats 2 can be adjusted. The sliding direction of the fixing seat 2 is perpendicular to the sliding direction of the mounting plate 1.

[0025] A horizontally distributed rotating shaft 3 is provided on each fixing seat 2, and the two ends of the rotating shaft 3 are rotatably connected to the two ends of the fixing seat 2. The above-mentioned product placement rack 5 is composed of two product fixing plates 51, and the backs of the two product fixing plates 51 are fixedly connected to the two rotating shafts 3 respectively. By rotating the rotating shaft 3, the angle between the two product fixing plates 51 can be adjusted.

[0026] The two product fixing plates 51 are arranged in a V shape and are used to limit the position of the product. The optical glass is placed obliquely between the two product fixing plates 51, and the adjacent sides of the optical glass are in contact with the two product fixing plates 51 respectively; a certain gap is left between the two product fixing plates 51 so that the edge of the optical glass can pass through the gap and be exposed downward to contact the grinding wheel 11.

[0027] According to the size and shape of the optical glass, the angle and the distance between the two product fixing plates 51 can be adjusted.

[0028] A locking mechanism is disposed at one end of the rotating shaft 3. When the angle between the two product fixing plates 51 is adjusted, the rotating shaft 3 can be locked by the locking mechanism to prevent the rotating shaft 3 from rotating.

[0029] A locking mechanism may also be provided on the fixing seat 2. When the distance between the two product fixing plates 51 is adjusted, the fixing seat 2 and the slide rail may be locked to prevent the fixing seat 2 from moving freely along the slide rail.

[0030] refer to Figure 2 On the two product fixing plates 51, a mounting groove is provided on one side close to the gap for installing a suction plate 12. The suction plate 12 has a plurality of suction holes. The upper surface of the suction plate 12 is flush with the surface of the product fixing plate 51. When the optical glass is placed on the product fixing plate 51, the suction holes on the suction plate 12 will generate negative pressure to suck and fix the optical glass to prevent the product from moving during the chamfering.

[0031] The suction plate 12 may be provided on one of the product fixing plates 51, or both of the product fixing plates 51 may be provided with the suction plate 12. The number of the suction plates 12 is not fixed, and may be one, two, or more than two.

[0032] refer to Figure 1 In this embodiment, the driving mechanism 4 adopts a screw rod 42 motor 41. The screw rod 42 motor 41 is arranged on one side of the mounting plate 1. The output end of the screw rod 42 motor 41 is connected to the screw rod 42. A connecting piece 10 is fixedly connected to one side of the mounting plate 1. The screw rod 42 is transmission-connected to the connecting piece 10. The screw rod 42 motor 41 drives the screw rod 42 to rotate, thereby driving the mounting plate 1 and the two product fixing plates 51 installed on the mounting plate 1 to move forward and backward. The edge of the optical glass on the product fixing plate 51 will slowly pass over the grinding wheel 11, and the grinding wheel 11 will chamfer the edge.

[0033] In other technical solutions, the driving mechanism 4 may also use a linear module or a cylinder to control the moving parts.

[0034] An electric switch is also provided on one side of the screw rod 42 and the motor 41 for controlling the operation of the screw rod 42 and the motor 41 .

[0035] like Figure 1As shown, the chamfering mechanism is composed of a driving motor 6, a speed regulator 9, a transmission shaft 7, a bearing seat 8 and other components, wherein the bearing seat 8 is arranged on one side of the mounting plate 1, and the transmission shaft 7 is rotatably connected to the bearing seat 8 through a bearing. A pulley and a grinding wheel 11 are respectively arranged at both ends of the transmission shaft 7, and the grinding wheel 11 is located directly below the gap between the two product fixing plates 51. The output end of the driving motor 6 is also connected to a pulley, and the two pulleys are connected by a synchronous belt. The driving motor 6 rotates, and the transmission shaft 7 is driven to rotate through the synchronous belt, thereby driving the grinding wheel 11 to rotate, and the edges of the optical glass are chamfered. The processing state diagram can be referred to Figure 3 .

[0036] The speed regulator 9 is electrically connected to the driving motor 6 to control the rotation speed of the driving motor 6 , thereby controlling the rotation speed of the grinding wheel 11 .

[0037] The chamfering mechanism can be integrally mounted on a plate, which can move up and down, so that the grinding wheel 11 can be controlled to move up and down, and then the up and down position of the grinding wheel 11 can be adjusted. When the up and down position of the grinding wheel 11 is adjusted, the driving mechanism 4 controls the mounting plate 1 to move, and the edge of the optical glass fixed on the product placement rack 5 will slowly contact the grinding wheel 11, and the edge will be chamfered.

[0038] A kettle 13 is also provided above the product placement rack 5, and the water outlet of the kettle 13 is connected to a water pipe 14. The water outlet end of the water pipe 14 extends to the top of the grinding wheel 11, providing cooling water for the grinding wheel 11 and the optical glass during chamfering, thereby reducing the friction temperature, improving the stability during processing, and preventing the optical glass from cracking.

[0039] like Figure 2 As shown, a portion of the bottom surface of the two product fixing plates 51 facing each other is cut away to prevent interference with the grinding wheel 11 during chamfering.

[0040] The above technical solutions only reflect the preferred technical solutions of the technical solutions of the present utility model. Some changes that may be made to certain parts thereof by technicians in this technical field all reflect the principles of the present utility model and fall within the protection scope of the present utility model.
