Abstract
Description
Technical Field
[0001] This utility model relates to the field of glass processing, and specifically to a glass grinding and polishing device. Background Technology
[0002] In the glass processing industry, grinding and polishing can improve the surface precision of glass. Traditional glass grinding and polishing processes generally employ a conveyor belt system with a single grinding disc. The specific process is as follows: the conveyor belt transports the glass to be processed one by one to the grinding disc station. After the glass is mechanically held in place, the grinding disc grinds and polishes only one side of the glass. After that side is finished, the glass needs to be manually removed from the conveyor belt, flipped, and then transported back to the grinding disc station for processing the other side. This traditional method is inefficient. Firstly, the single-station, single-process method results in equipment downtime, preventing continuous operation. Utility Model Content

[0012] The following is a description of the embodiments and appendices. Figures 1-3 The technical solution of this utility model will be further described below.
[0013] Example 1 A glass grinding and polishing apparatus includes: a frame 1, a processing base 2, a grinding disc 3, a lower rotary drive assembly 4, a lifting assembly 5, an upper rotary assembly 8, a turntable 6, and a vacuum adsorption disc assembly 7. The processing base 2 is mounted on the frame 1, and the grinding disc 3 is rotatably mounted inside the processing base 2. The lower rotary drive assembly 4 is located at the lower end of the frame 1 and connected to the grinding disc 3. The lifting assembly 5 is symmetrically arranged on the frame 1. The upper rotary assembly 8 is mounted on a movable base 53 of the lifting assembly 5. The turntable 6 is located inside the upper rotary assembly 8 and includes an upper cavity 61. The vacuum adsorption disk assembly 7 is provided in several groups and located in the upper cavity 61 and the lower cavity 62. The vacuum adsorption disk assembly 7 includes a vacuum generator 71, an adsorption base 72 and an adsorption upper disk 73. The vacuum generator 71 is located inside the turntable 6. The adsorption base 72 is provided in the upper cavity 61 or the lower cavity 62 and is connected to the vacuum generator 71 through a pipe. The adsorption upper disk 73 is threadedly connected to the adsorption base 72. The adsorption upper disk 73 is provided with several groups of adsorption chambers 74. The adsorption chambers 74 are provided with guide holes 75 that communicate with the adsorption base 72.
[0014] like Figures 1-3 As shown, the working principle of this utility model is as follows: The turntable 6 is divided into an upper cavity 61 and a lower cavity 62, and vacuum adsorption disk assemblies 7 are arranged in both cavities. When the vacuum generator 71 is working, it delivers negative pressure to the adsorption base 72 through a pipe. The negative pressure is transmitted to the adsorption chamber 74 through the guide hole 75 of the upper adsorption disk 73, so that a negative pressure environment is formed in the adsorption chamber 74, thereby firmly adsorbing the glass to be processed onto the surface of the upper adsorption disk 73.
[0015] The lifting assembly 5 is symmetrically arranged on the side fixed seat 11 of the frame 1, and can drive the upper rotating assembly 8 and the turntable 6 to lift as a whole. When the glass to be processed is adsorbed onto the adsorption plate 73 of the lower cavity 62, the lifting assembly 5 adjusts the turntable 6 to descend, so that the lower surface of the glass is precisely in contact with the rotating grinding disc 3, and the first surface (lower surface) is ground and polished; after the first surface is processed, the lifting assembly 5 drives the turntable 6 to rise.
[0016] The upper rotating component 8 is connected to the rotating shaft 63 of the turntable 6. When the turntable 6 rises to a safe position, the upper rotating component 8 drives the turntable 6 to rotate 180°. At this time, the glass that has completed the first side processing flips with the lower cavity 62 to the position of the upper cavity 61, waiting for the second side processing. At the same time, the glass to be processed that has been pre-adsorbed in the upper cavity 61 flips to the position of the lower cavity 62. The lifting component 5 drives the turntable 6 to descend again, so that the new glass to be processed fits with the grinding disc 3, and the second batch of first side grinding and polishing is started. During this process, the processed glass in the upper cavity 61 can be unloaded and new glass can be loaded simultaneously, realizing the cross operation of grinding and polishing and loading and unloading.
[0017] By operating the upper and lower cavities in a cross manner, the grinding disc can remain in operation without waiting for the glass to be flipped or loaded, eliminating the equipment downtime in traditional processes. At the same time, the parallel processing mode of the upper and lower cavities is equivalent to transforming single-station processing into dual-station alternating processing, which greatly improves processing efficiency compared to the traditional conveyor belt mode.
[0018] The vacuum adsorption plate assembly uses negative pressure adsorption, and the adsorption force is evenly distributed in the adsorption chamber, which can avoid the glass deformation caused by traditional mechanical pressing. In addition, the upper adsorption plate and the lower adsorption plate are threadedly connected, and the appropriate model can be quickly changed according to different sizes and shapes of glass, which is highly versatile and ensures accurate positioning of glass during the grinding process.
[0019] As a further preferred embodiment, the upper end of the frame 1 is provided with a side fixing seat 11, the lifting assembly 5 includes a motor 51, a lead screw 52, a lead screw nut 54 and guide posts 55, the guide posts 55 are symmetrically arranged in the side fixing seat 11, the motor 51 is fixed to the lower end of the side fixing seat 11, the lead screw 52 is rotatably arranged on the side fixing seat 11 and located between the guide posts 55, the output end of the motor 51 is connected to the lead screw 52, the lead screw nut 54 is arranged on the lead screw 52, the movable seat 53 is fixedly connected to the lead screw nut 54 and slidably sleeved on the guide posts 55, and the turntable 6 is rotatably arranged on the side fixing seat 11 through a rotating shaft 63 and the end is connected to the upper rotating assembly 8. When motor 51 drives lead screw 52 to rotate, lead screw nut 54 moves along lead screw 52 axially under the action of thread driving force, thereby driving moving seat 53 to make smooth lifting and lowering motion along guide post 55; since upper rotating component 8 is fixed on moving seat 53, turntable 6 rises and falls synchronously with moving seat 53 to realize the distance adjustment between glass and grinding disc 3.
[0020] As a further preferred embodiment, the bottom of the processing base 2 is provided with a liquid outlet pipe 21. This allows the coolant (containing grinding debris) in the cavity to be quickly discharged to an external recovery or filtration system.
[0021] As a further preferred embodiment, the upper cavity 61 or the lower cavity 62 is provided with four sets of adsorption base plates 72 and adsorption upper plates 73. The four sets of adsorption components can simultaneously adsorb four pieces of glass of different specifications to be processed, adapting to different glass processing needs; during the grinding process, the four pieces of glass are synchronously attached to the grinding disc 3, and after the first surface processing is completed, they are rotated to the upper cavity 61 with the turntable 6, and then unloading and loading are performed synchronously.
[0022] The preferred embodiments of this utility model have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of this utility model without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of this utility model through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
