Description

Technical Field

[0001] This utility model belongs to the field of glass grinding and polishing technology, and in particular relates to a grinding and polishing mechanism for a glass drilling and polishing equipment. Background Technology

[0002] Glass drilling, grinding, and polishing is a comprehensive processing technology that integrates drilling, grinding, and polishing. Drilling uses carbide drill bits, ultrasonic or laser technologies to form the required holes in the glass. Grinding removes surface defects or forming allowances through a combination of mechanical and chemical actions, determining the shape, size, and flatness. Polishing further eliminates the pitted layer and underlying crack layer produced by grinding, resulting in a smooth, transparent, and glossy mirror-like surface.

[0003] Chinese patent publication number 202023107337.2 discloses a glass surface polishing machine structure, belonging to the field of glass production technology. The glass surface polishing machine structure includes a machine body and a fixing device. A polishing device is provided on the machine body, and a fixing device is located at the bottom of the machine body. Movable grooves are provided on opposite sides of the machine body. The polishing device passes through the movable grooves and is inclinedly mounted on the machine body. A water spraying device is provided on the side of the machine body near the movable grooves. Two sliding strips are provided on the side wall of the machine body near the movable grooves. A first running block is provided on the two sliding strips on one side of the machine body, and a second running block is provided on the two sliding strips on the other side of the machine body. A first cylinder is provided on one side of the first running block, and a third cylinder is provided on one side of the second running block. This design solves the problem that when the glass thickness is too thick, the polishing machine can only polish one edge at a time, and cannot polish both edges of the glass cut surface simultaneously.

[0004] However, existing technologies have the following problems when used: The existing glass drilling and polishing equipment often suffers from severe vibration during high-speed operation. This vibration is easily transmitted to the polishing components through the drive structure, resulting in reduced polishing accuracy and easy damage to the components. The polishing mechanism has poor adaptability to glass with different profiles, making it difficult to ensure stable adhesion between the polishing components and the glass surface, thus affecting processing accuracy. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a polishing mechanism for a glass drilling and polishing equipment, comprising: An isolation shell, wherein a rotating shaft is rotatably disposed inside the isolation shell, and a power component for driving the rotating shaft to rotate is disposed on the isolation shell; A trimming part is provided at the bottom end of the rotating shaft. The top of the trimming part is provided with a mounting groove. The bottom end of the rotating shaft is provided with an extension part and is provided in the inner cavity of the mounting groove. The inner cavity of the mounting groove is provided with a contact part for counteracting vibration of the trimming part. The grinding assembly, located at the bottom of the dressing section, is used to grind and polish the glass. A buffer assembly, located on the outside of the rotating shaft, is used to buffer the trimming part; The cooling assembly, located inside the isolation housing, is used for water cooling of the polished glass. An abutment component, located at the bottom of the isolation housing, is used to enable the isolation housing to adapt to glass with different profiles.

[0006] Furthermore, the power component includes a motor housing, which is fixedly connected to the top of the isolation shell. A drive motor for driving the rotating shaft to rotate is disposed inside the motor housing. A universal joint is disposed on the top of the motor housing, and the universal joint is connected to an external robotic arm.

[0007] Furthermore, the bottom of the inner cavity of the mounting groove is provided with extension grooves at both ends, and the bottom of the contact portion is provided with an extension portion that matches the extension groove.

[0008] Furthermore, the buffer assembly includes a fixing ring with a buffer groove, an extension rod slidably disposed in the inner cavity of the buffer groove, a positioning groove on the top of the trimming part, and the bottom end of the extension rod penetrating the inner cavity of the buffer groove and extending to the inner cavity of the positioning groove.

[0009] Furthermore, a positioning block is fixedly connected to the top of the extension rod, and a spring is fixedly connected between the bottom of the positioning block and the bottom of the inner cavity of the buffer groove, with the spring sleeved on the outside of the extension rod.

[0010] Furthermore, the cooling assembly includes a water spray head, which is fixedly connected to the inner wall of the isolation shell. One end of the water spray head is connected to a connecting pipe, which is connected to an external water pump.

[0015] Compared with the prior art, the grinding and polishing mechanism of the glass drilling and polishing equipment of this utility model has the following advantages: 1. The anti-vibration structure is formed by the contact part in the mounting groove of the trimming part and the buffer assembly on the outside of the rotating shaft. The contact part acts on the connection area between the extension of the rotating shaft and the mounting groove, while the buffer assembly weakens the impact and vibration transmission of grinding and polishing through the elastic structure, reduces the vibration amplitude under high-speed operation, avoids the interference of vibration on the grinding and polishing accuracy, and at the same time reduces the wear of parts caused by vibration and extends the service life of the mechanism. 2. The contact component at the bottom of the isolation shell utilizes the elastic deformation characteristics of the flexible ball to drive the contact ring to adaptively adjust its contact posture according to the different contours of the glass, ensuring that the polishing component and the glass surface are always stably attached, improving the poor adaptability of traditional mechanisms, and ensuring stable and reliable polishing operation quality.

[0022] like Figures 1-5 As shown, a glass grinding and polishing mechanism of a glass drilling and polishing equipment includes: An isolation shell 100 is provided, and a rotating shaft 130 is rotatably disposed inside the isolation shell 100. A power component for driving the rotating shaft 130 to rotate is provided on the isolation shell 100. A trimming part 200 is provided at the bottom end of the rotating shaft 130. A mounting groove 220 is provided at the top of the trimming part 200. An extension part 131 is provided at the bottom end of the rotating shaft 130 and is provided in the inner cavity of the mounting groove 220. A contact part 230 for damping vibration of the trimming part 200 is provided in the inner cavity of the mounting groove 220. A grinding assembly, located at the bottom of the trimming section 200, is used to grind and polish the glass. A buffer assembly is provided on the outside of the rotating shaft 130 to buffer the trimming part 200; A cooling assembly, located inside the isolation housing 100, is used for water cooling of the polished glass. An abutment component is provided at the bottom of the isolation housing 100 to enable the isolation housing 100 to adapt to glass with different profiles.

[0023] As a preferred example of this utility model, the rotating shaft 130 inside the isolation shell 100 provides rotational support space and is also protected by a buffer assembly; the power component is mounted on the isolation shell 100 and can provide continuous and stable rotational power to the rotating shaft 130; the extension 131 at the bottom end of the rotating shaft 130 is embedded in the mounting groove 220 at the top of the trimming part 200, so that the two form a linkage; and the contact portion 230 inside the mounting groove 220 can act on the connection area between the extension 131 and the mounting groove 220 to counteract the vibration generated by the trimming part 200 during high-speed operation; the bottom of the trimming part 200... The grinding component, as the working part, receives the power of the rotating shaft 130 to perform grinding and polishing operations on the glass. The buffer component on the outside of the rotating shaft 130 and the contact part 230 form a protective barrier, reducing the impact and vibration during the grinding and polishing process and ensuring operational stability. The cooling component inside the isolation shell 100 can deliver coolant to the grinding and polishing area in a targeted manner, and remove the heat of operation in a timely manner through water cooling to prevent the glass from cracking or breaking due to high temperature. The contact component at the bottom of the isolation shell 100 can adaptively adjust the contact state according to the different contours of the glass, improving the accuracy of glass grinding and polishing and the adaptability of the equipment.

[0024] In the example of this application, the power component includes a motor housing 120, which is fixedly connected to the top of the isolation shell 100. A drive motor for driving the rotation shaft 130 to rotate is provided inside the motor housing 120, and a universal joint 110 is provided on the top of the motor housing 120. The universal joint 110 is connected to the external robotic arm.

[0025] As a preferred example of this utility model, the motor housing 120 is securely mounted on the top of the isolation shell 100 by a fixed connection. The power component is rigidly connected to the isolation shell 100, and the drive motor drives the rotating shaft 130 to rotate at a set speed to provide power for the grinding and polishing operation. The universal joint 110 provided on the top of the motor housing 120 serves as a connection bridge between the equipment and the external robotic arm. The universal joint 110 itself has the characteristic of multi-directional rotation, which enables the equipment to follow the robotic arm to adjust the working angle and position.

[0026] In the example of this application, the bottom ends of the inner cavity of the mounting groove 220 are provided with extension grooves 221, and the bottom of the contact portion 230 is provided with an extension portion 231 that is adapted to the extension grooves 221.

[0027] As a preferred example of this utility model, the engagement of the extension groove 221 and the extension portion 231 increases the contact area between the contact portion 230 and the inner wall of the mounting groove 220. When the trimming part 200 is subjected to the impact force of grinding and polishing, the engagement of the extension portion 231 and the extension groove 221 can limit the displacement of the contact portion 230, prevent its vibration offset effect from weakening due to positional displacement, and ensure that the contact portion 230 can always act precisely on the connection area between the extension portion 131 of the rotating shaft 130 and the mounting groove 220, thus providing a guarantee for the stable operation of the trimming part 200.

[0028] In the example of this application, the buffer assembly includes a fixing ring 140, a buffer groove 144 is provided on the fixing ring 140, an extension rod 143 is slidably provided in the inner cavity of the buffer groove 144, a positioning groove 210 is provided on the top of the trimming part 200, and the bottom end of the extension rod 143 passes through the inner cavity of the buffer groove 144 and extends to the inner cavity of the positioning groove 210.

[0029] As a preferred example of this utility model, the buffer assembly uses a fixed ring 140 as the mounting base. The fixed ring 140 is positioned by cooperating with the rotating shaft 130. The buffer groove 144 provided by the fixed ring 140 provides sliding space for the extension rod 143. The extension rod 143 can slide flexibly along the axial direction within the cavity of the buffer groove 144. At the same time, its bottom end extends through the buffer groove 144 and into the positioning groove 210 at the top of the trimming part 200, forming a flexible connection structure between the trimming part 200 and the fixed ring 140. When the trimming part 200 is subjected to an upward impact force or vibrates during the polishing process, the extension rod 143 will slide along the buffer groove 144 under the drive of the positioning groove 210. This sliding buffering effect weakens the transmission of impact force and prevents vibration from being directly transmitted to the rotating shaft 130, affecting the overall operational stability. At the same time, this connection method can also ensure the synchronous operation of the trimming part 200 and the rotating shaft 130, without affecting the continuity and accuracy of the polishing operation.

[0030] In the example of this application, a positioning block 141 is fixedly connected to the top of the extension rod 143, and a spring 142 is fixedly connected between the bottom of the positioning block 141 and the bottom of the inner cavity of the buffer groove 144. The spring 142 is sleeved on the outside of the extension rod 143.

[0031] As a preferred example of this utility model, the positioning block 141 at the top of the extension rod 143 forms a limiting and protective structure. Its size is larger than the opening size of the buffer groove 144, which can effectively prevent the extension rod 143 from detaching from the buffer groove 144 during sliding, ensuring the integrity of the buffer assembly structure. The spring 142 connecting the bottom of the positioning block 141 and the bottom of the inner cavity of the buffer groove 144 is sleeved on the outside of the extension rod 143 to form an elastic support. When the extension rod 143 slides upward under impact, the spring 142 is compressed and generates elastic deformation, converting the impact energy into elastic potential energy. Then, the spring 142 pushes the extension rod 143 to reset through the rebound, optimizing the buffer performance of the buffer assembly, reducing the vibration amplitude of the trimming part 200, and improving the accuracy of the grinding and polishing operation and the stability of the mechanism operation.

[0032] In the example of this application, the cooling assembly includes a water spray head 170, which is fixedly connected to the inner wall of the isolation housing 100. One end of the water spray head 170 is connected to a connecting pipe 171, which is connected to an external water pump.

[0033] As a preferred example of this utility model, the connecting pipe 171 connected to one end of the spray head 170 serves as a coolant delivery channel, forming a complete coolant supply system with the external water pump. When the equipment is performing grinding and polishing operations, the external water pump delivers coolant to the spray head 170 through the connecting pipe 171. The spray head 170 sprays the coolant in an atomized manner onto the grinding and polishing contact surface, which can remove a large amount of heat generated during the grinding and polishing process and prevent the glass from deforming or cracking due to local high temperature.

[0034] In the example of this application, the abutment component includes an abutment ring 150, and an annular groove 161 is provided at the bottom of the isolation shell 100. Multiple sets of flexible balls 162 are fixedly disposed in the inner cavity of the annular groove 161, and the abutment ring 150 is fixedly connected to the multiple sets of flexible balls 162.

[0035] As a preferred example of this utility model, the annular groove 161 at the bottom of the isolation shell 100 provides installation space for the flexible ball 162. Multiple sets of flexible balls 162 are evenly distributed in the inner cavity of the annular groove 161 and are fixedly connected to the contact ring 150 to form an elastic support structure. The flexible ball 162 itself has elastic deformation capability. When the device acts on the glass surface with different contours, the contact ring 150 contacts the glass surface and generates pressure. This pressure will cause the flexible ball 162 to deform adaptively according to the glass contour, and drive the contact ring 150 to adjust its own contact posture to ensure that the contact ring 150 can fit tightly with the glass surface and prevent the isolation shell 100 from tilting due to changes in the glass contour.

[0036] In the example of this application, the bottom of the abutment ring 150 is provided with a drainage groove 151 in an annular shape.

[0037] As a preferred example of this utility model, the drainage groove 151 at the bottom of the contact ring 150 forms a drainage channel. The coolant generated during the polishing process and the glass debris washed off will collect in the contact area between the contact ring 150 and the glass under the action of gravity. At this time, the drainage groove 151 can drain these accumulated liquids and debris, avoiding the accumulation of liquids on the glass surface and affecting the polishing accuracy.

[0038] In the example of this application, the grinding assembly includes a grinding block 250, which is fixedly connected to the bottom of the trimming part 200.

[0039] As a preferred example of this utility model, when the rotating shaft 130 drives the trimming part 200 to rotate, the grinding block 250 can operate synchronously with the trimming part 200, so that the polishing force is transmitted to the glass surface.

[0040] In the example of this application, a bolt 240 is provided at the bottom of the trimming part 200, and the trimming part 200 is connected to the bottom end of the rotating shaft 130 by the bolt 240, and the contact part 230 is located outside the bolt 240.

[0041] As a preferred example of this utility model, the connection between the trimming part 200 and the bottom end of the rotating shaft 130 is achieved by bolts 240, which facilitates the installation, disassembly and maintenance of the trimming part 200. When the trimming part 200 or the grinding component is worn and needs to be replaced, the component can be replaced simply by removing the bolts 240, thereby reducing maintenance costs and downtime.

[0042] In practical use, the universal joint 110 is connected to the external robotic arm. The inner cavity of the isolation housing 100 is equipped with a cooling assembly, which includes a water spray head 170 fixedly connected to the inner wall of the isolation housing 100. One end of the water spray head 170 is connected to a connecting pipe 171 that is connected to an external water pump. The bottom of the isolation housing 100 is equipped with an abutment assembly, which includes an abutment ring 150. An annular groove 161 is formed at the bottom of the isolation housing 100, and multiple sets of flexible balls 162 are fixedly arranged inside the annular groove 161. The abutment ring 150 is fixedly connected to the multiple sets of flexible balls 162, and a drainage groove 151 is formed annularly at the bottom of the abutment ring 150. During operation, the drive motor drives the rotating shaft 130 to rotate. The rotating shaft 130... The extension 131 and the mounting groove 220 are engaged and connected by bolts 240, which drives the trimming part 200 to rotate synchronously. The trimming part 200 drives the grinding block 250 at the bottom to rotate to grind and polish the glass. The extension rod 143 in the buffer assembly slides in the buffer groove 144 with the movement of the trimming part 200, and the spring 142 deforms accordingly. The external water pump in the cooling assembly delivers coolant to the spray head 170 through the connecting pipe 171. The spray head 170 delivers the coolant to the grinding and polishing area. The contact ring 150 in the contact assembly contacts the glass surface. The flexible ball 162 deforms adaptively according to the glass contour. The coolant and glass debris generated during the grinding and polishing process are discharged through the drainage groove 151 at the bottom of the contact ring 150.

Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive.
