[0020] This utility model proposes a grinding device 100.

[0021] Please see Figures 1 to 6 In one embodiment of the present invention, the main grinding device 100 includes: a mounting bracket 1 and a grinding assembly 2. The mounting bracket 1 includes a base 11 and a mounting frame 12 disposed on the base 11. The base 11 and the mounting frame 12 enclose a mounting space 1a. The grinding assembly 2 is movably disposed on the mounting frame 12 and located within the mounting space 1a. The grinding assembly 2 is provided with a grinding head 21 and a first driving member 25. The first driving member 25 drives the grinding head 21 to rotate within the mounting space 1a.

[0022] In one embodiment, the mounting bracket 1 is the foundation of the entire grinding apparatus 100, providing necessary support and stability for the grinding process. The mounting bracket 1 includes a carrier 11 for supporting the product to be ground and a mounting frame 12 disposed on the carrier 11. The carrier 11 and the mounting frame 12 enclose an installation space 1a. Specifically, the connection can be detachable by bolts or clips, or by welding or fixing, to reliably connect the carrier 11 and the mounting frame 12. The bottom of the carrier 11 needs to be flat. The carrier 11 is usually fixed on a workbench or the ground to ensure that the grinding accuracy is not affected by vibration or movement during the grinding process. The design of the carrier 11 needs to consider compatibility with the mounting frame 12 and other components to ensure that they can be correctly installed and work together. To increase the adhesion between the product and the carrier 11, the carrier 11 can be made of silicone, which can compensate for the lack of flatness of the product to be ground. At the same time, silicone is relatively soft, which is beneficial for protecting the product. The LCD is embedded in a portion of the silicone, so that only a portion of the LCD edge is exposed. This reduces the chance of the grinding head 21 hitting the LCD edge during rotation, thus preventing micro-cracks that could reduce the LCD's strength. The mounting frame 12 needs to be made of durable materials, such as cast iron, carbon steel, or alloys. These materials have high strength, strong wear resistance, and a certain weight so that the base can withstand the forces and pressures that may be generated during the grinding process.

[0023] In one embodiment, the grinding assembly 2 serves as the mounting carrier for grinding equipment such as the grinding head 21 and the first drive member 25. The first drive member 25 drives the grinding head 21 to rotate, and the grinding assembly 2 causes the grinding head 21 to make necessary adjustments and positioning during the grinding process. The first drive member 25 can be a motor or a pneumatic drive device. The grinding assembly 2 and the mounting frame 12 are typically connected by a sliding connection, such as a guide rail, a slider, or a bearing 13, to achieve smooth vertical movement on the carrier 11. It should be noted that the grinding assembly 2 generally consists of multiple parts, such as the first drive member 25, the second drive member 22, the grinding head 21, and a control system. The grinding head 21 is used for physical grinding of the glass plate surface.

[0024] The grinding assembly 2 may contain grinding media, such as abrasive or slurry, which help improve grinding efficiency and quality. To accommodate glass plates of different sizes and shapes, the grinding assembly 2 may be designed to be adjustable, allowing the user to adjust the position or pressure of the grinding head 21. The design of the grinding assembly 2 should ensure precise control of the grinding process to avoid over-grinding or uneven grinding, which is crucial for improving yield and product quality. Due to the significant wear during the grinding process, the materials and construction of the grinding assembly 2 need to be highly durable to withstand prolonged use. The design of the grinding assembly 2 should facilitate maintenance and replacement of worn parts, such as the grinding head 21 or drive components.

[0025] The technical solution of this utility model involves designing a grinding device 100, which consists of two parts: a mounting bracket 1 and a grinding assembly 2. The mounting bracket 1 comprises a carrier 11 for placing the glass plate to be ground and a mounting frame 12, which together enclose an installation space 1a. The grinding assembly 2 is installed within the installation space 1a and includes a grinding head 21 and a first driving member 25. The first driving member 25 is responsible for driving the grinding head 21 to rotate within the installation space 1a, and the grinding head 21 can move closer to or further away from the carrier 11 as needed. This design makes the grinding device more compact, reduces the floor space, improves the flexibility and efficiency of grinding, facilitates rapid rework grinding on the production line, thereby reducing production costs and improving production efficiency and product quality.

[0026] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The grinding assembly 2 is provided with a connecting plate 23 and a fixing plate 24. Both the connecting plate 23 and the fixing plate 24 are located in the installation space 1a. The connecting plate 23 and the fixing plate 24 enclose a driving space 2a. The driving space 2a is located in the installation space 1a. The first driving component 25 is located in the driving space 2a and is connected to the fixing plate 24.

[0027] In one embodiment of this utility model, the grinding assembly 2 includes a connecting plate 23 and a fixing plate 24, both of which are located within the mounting space 1a formed by the mounting bracket 1. The connecting plate 23 and the fixing plate 24 are arranged opposite to each other, together enclosing a closed driving space 2a, which is completely inside the mounting space 1a. Within this driving space 2a, a first driving member 25 is provided, which is responsible for driving the grinding head 21 to perform grinding operations. The first driving member 25 is connected to the fixing plate 24 by bolts, pins, or other fixing methods to ensure stability and efficient power transmission during the grinding process. This design allows the first driving member 25 to effectively transmit power to the grinding head 21 while maintaining the compactness and ease of operation of the entire grinding assembly.

[0028] In the embodiments of this utility model, please refer to Figure 3 The grinding assembly 2 is provided with a protective cover 27, which is located in the installation space 1a. The protective cover 27 is connected to the fixing plate 24. The protective cover 27 and the carrier 11 enclose the grinding space 27a, which is located in the installation space 1a. The grinding head 21 rotates through the protective cover 27 and is located in the grinding space 27a.

[0029] In this embodiment, the grinding assembly 2 is equipped with a dedicated protective cover 27, which is connected to the fixing plate 24 and located inside the mounting space 1a of the entire grinding device. The connection between the protective cover 27 and the fixing plate 24 can be achieved through various mechanical connection methods, such as using screws, clips, or other fasteners. The protective cover 27 is not only designed to protect the grinding head 21 from accidental contact during operation, but also, together with the carrier 11, forms a closed grinding space 27a. This grinding space 27a is specifically designed to accommodate the product to be ground and ensure the safety and stability of the grinding process. The grinding head 21 is designed to pass through a specific opening in the protective cover 27, or has a dedicated channel, allowing the grinding head 21 to rotate freely inside the protective cover 27. Simultaneously, the entire grinding head 21 is located within the grinding space 27a enclosed by the protective cover 27 and the carrier 11. This protects the operator's safety during grinding and prevents grinding debris or liquid from splashing, ensuring a clean grinding environment.

[0030] In the embodiments of this utility model, please refer to Figure 1 and Figure 3 The grinding assembly 2 is provided with a guide shaft 26, which slides through the mounting frame 12, and one end of the guide shaft 26 is connected to the connecting plate 23.

[0031] In one embodiment, the guide shaft 26 of the grinding assembly 2 is designed to slide through the mounting frame 12, ensuring precise positioning and stable movement of the grinding head 21. One end of the guide shaft 26 is connected to the connecting plate 23, typically via bolts, pins, or other fasteners. This connection method not only provides robust support but also allows for adjustment or replacement of the guide shaft 26 as needed. The sliding characteristics of the guide shaft 26 reduce friction, improving the smoothness and efficiency of the grinding process. Furthermore, the design of the guide shaft 26 also considers maintenance and durability, extending the service life of the entire grinding device by selecting appropriate materials and surface treatments, such as hard chrome plating, to enhance its wear resistance and corrosion resistance. This design enables precise control of the grinding head 21 within the mounting space 1a, improving grinding quality while also making the equipment more compact and easier to maintain.

[0032] In the embodiments of this utility model, please refer to Figure 3 The mounting frame 12 has a guide hole 2b, and a bearing 13 is installed in the guide hole 2b. The bearing 13 is snapped into the guide hole 2b, and the guide shaft 26 slides through the bearing 13.

[0033] In one embodiment, the mounting frame 12 is designed to have at least one guide hole 2b, in which a bearing 13 is installed. The bearing 13 is used to ensure that the guide shaft 26 can move smoothly in a straight line.

[0034] To secure the bearing 13 and limit its movement within the guide hole 2b, the bearing 13 is snapped and positioned within the guide hole 2b. When the guide shaft 26 needs to move within the mounting frame 12, it can slide through the bearing 13, which provides the necessary support and guidance. This design not only ensures the precise movement of the guide shaft 26 but also helps maintain the stability and reliability of the entire grinding apparatus. In this way, the grinding assembly 2 can perform grinding operations efficiently while maintaining a compact structure and ease of operation.

[0035] In the embodiments of this utility model, please refer to Figure 2 and Figure 3 The mounting frame 12 is provided with a second driving component 22, which is connected to the mounting frame 12, and the driving end of the second driving component 22 is connected to the connecting plate 23.

[0036] In embodiments of this invention, the second driving component 22 is typically connected to the mounting frame 12 via bolts, pins, couplings, or gears to ensure stable connection and power transmission between the second driving component 22 and the mounting frame 12. The second driving component 22 can generally be a cylinder or a motor. The driving end of the second driving component 22 is connected to the connecting plate 23 via a snap-fit ​​or bolt, allowing the output power of the second driving component 22 to be effectively transmitted to the connecting plate 23, thereby driving the grinding assembly 2 to perform grinding operations. This design enables the grinding device to precisely control the movement of the grinding head 21, improving grinding efficiency and quality.

[0037] In the embodiments of this utility model, please refer to Figure 1 and Figure 2 A pressure sensor 3 is also provided between the second drive component 22 and the connecting plate 23. The pressure sensor 3 is electrically connected to the first drive component 25 and / or the second drive component 22.

[0038] In this embodiment of the invention, the connection between the second drive member 22 and the connecting plate 23 is achieved by setting a pressure sensor 3, which is responsible for monitoring and adjusting the pressure acting on the grinding head 21. The pressure sensor 3 is electrically connected to the first drive member 25 and / or the second drive member 22 to ensure that the pressure sensor 3 can effectively receive signals from the drive members and make corresponding adjustments. To control the matching degree between grinding speed and pressure, the downward pressure and grinding speed of the second drive member are adjustable. Specifically, a pressure sensor 3 is installed between the output end of the second drive member 22 and the connecting plate 23, and is connected to the drive member through an electrical circuit or wireless communication module. The pressure sensor 3 detects the pressure changes during the grinding process in real time and transmits the data to the control unit. The control unit adjusts the working state of the drive member according to the preset pressure parameters to achieve precise control of the grinding pressure and grinding speed. This design not only improves the grinding accuracy but also enhances the intelligence level of the equipment, ensuring the consistency and reliability of the grinding quality.

[0039] In the embodiments of this utility model, please refer to Figures 4 to 6 The carrier 11 has an airflow channel 11a and a pressure regulating hole 11b communicating with the airflow channel 11a. The pressure regulating hole 11b is located on the side of the carrier 11 facing the grinding assembly.

[0040] In one embodiment, the carrier 11 has an airflow channel 11a, the purpose of which is to control the airflow through the carrier 11. On one side of the carrier 11, pressure regulating holes 11b are provided, which communicate with the airflow channel 11a, allowing for adjustment and control of the airflow. The pressure regulating holes 11b are located on the side of the carrier 11 facing the grinding assembly, ensuring that the airflow acts directly on the bottom of the product to be ground, thereby securing the product or detaching it from the carrier 11. The design of the pressure regulating holes 11b allows the operator to adjust the size and direction of the airflow according to the grinding needs, optimizing the grinding effect.

[0041] In the embodiments of this utility model, please refer to Figure 4 The carrier 11 is also provided with a sealing groove 11c, and the carrier 11 includes a sealing ring 111 that is snapped into the sealing groove 11c.

[0042] In this embodiment, the carrier 11 has a sealing groove 11c to accommodate the installation of the sealing ring 111. Specifically, the sealing groove 11c is machined into the outer periphery of the end of the carrier 11 near the protective cover 27. The sealing groove 11c is designed to fix the sealing ring 111 and ensure that it provides a good sealing effect during the grinding process. The size and shape of the sealing groove 11c are determined according to the specifications of the sealing ring 111 to ensure that the sealing ring 111 can be correctly installed in the groove. The material of the sealing ring 111 is generally rubber or silicone or other elastic materials. The sealing ring 111 can be installed in various ways, such as by mechanical pressure, adhesive, or special installation tools. After installation, the sealing ring 111 will form a sealed fit with the carrier 11, preventing liquid or particulate matter from entering the grinding area, thereby protecting the grinding components and improving the overall performance of the grinding device.
