Description

Technical Field

[0001] This utility model belongs to the field of rearview mirror glass polishing technology, specifically relating to a side polishing device for rearview mirror glass. Background Technology

[0002] As a key component of transportation vehicles, the smoothness of the rearview mirror glass directly affects the assembly accuracy, safety of use, and appearance quality. In the production process of rearview mirror glass, side grinding is one of the core processes, which requires removing burrs and sharp corners after glass cutting to form a smooth transition surface on the side.

[0003] According to the authorized announcement number CN221539219U, a glass side grinding device is known prior art. This patent uses the sliding connection between the movable plate and the base in the glass fixing assembly, combined with the use of an electric push rod, to make the glass easy to move and actively grind it close to the grinding plate. However, the technical solution of this patent still has the following defects in actual use: the glass plate is fixed only by the installation and pressure plate on both sides. During grinding, the vibration generated is mainly concentrated at the grinding end of the glass plate. Since there is no fixing mechanism here, the vibration can easily cause the glass plate to chip, affecting the processing efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a side grinding device for rearview mirror glass to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a side grinding device for rearview mirror glass, including a grinding table, a movable block movably disposed at the top of the grinding table, a rearview mirror glass plate being adsorbed and connected to the top of the movable block, a synchronously lifting grinding component and a pressing component being disposed on the side of the rearview mirror glass plate to be ground, the pressing component including an upper pressing block and a lower pressing block, the upper pressing block and the lower pressing block being elastically pressed against the upper and lower surfaces of the rearview mirror glass plate, and the side of the rearview mirror glass plate to be ground extending beyond the upper pressing block and the lower pressing block, the grinding component and the extended end of the rearview mirror glass plate being fitted together, the grinding component including a grinding machine.

[0006] In a preferred embodiment, an electric slide rail and an electric vertical rail are fixedly connected to the top of the grinding table. A lifting platform is slidably installed on the side of the electric vertical rail near the moving block. An electric push rod is fixedly connected to one side of the lifting platform. A fixed frame is fixedly connected to one end of the electric push rod. A connecting frame is fixedly connected to the bottom end of the fixed frame. Two first spring telescopic rods are fixedly connected to the bottom end of the connecting frame. The upper pressure block is fixedly connected to the bottom end of the two first spring telescopic rods.

[0007] In a preferred embodiment, a second spring telescopic rod is fixedly connected between the bottom end of the lower pressure block and the top end of the grinding table, and the lower pressure block and the upper pressure block are vertically corresponding.

[0008] In a preferred embodiment, a vacuum cleaner is fixedly connected to both the connecting frame and the top of the grinding table. An adsorption groove is provided on the side of the upper and lower pressure blocks near the grinding machine. A pipe is provided between the two adsorption grooves and the corresponding vacuum cleaners. An adsorption hole is provided on the opposite side of the lower and upper pressure blocks. The adsorption hole is connected to the corresponding adsorption groove.

[0009] In a preferred embodiment, the grinder is fixedly connected to the bottom end of the mounting frame.

[0010] In a preferred embodiment, the movable block is slidably mounted on an electric slide rail, and a suction cup is fixedly connected to the top of the movable block, with the bottom of the rearview mirror glass plate adsorbed onto the suction cup.

[0011] In a preferred embodiment, the upper and lower pressure blocks have the same length, and the length values ​​of the upper and lower pressure blocks are greater than the side length value of the rearview mirror glass plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: This side-grinding device for rearview mirror glass panels allows the grinding component and the clamping component to rise and fall synchronously. This ensures that the grinding component aligns with the side of the rearview mirror glass panel, while the clamping component presses and fixes the grinding side together. The upper and lower pressure blocks, through the elastic force of the spring telescopic rod, concentrate the clamping force on the upper and lower surfaces of the grinding side, effectively suppressing vibration and displacement during grinding and preventing edge chipping during the grinding of the rearview mirror glass panel. After the lower and upper pressure blocks are clamped in the rearview mirror glass panel, the vacuum cleaner is turned on, and the suction holes generate suction force, which acts on the upper and lower surfaces of the rearview mirror glass panel to enhance the connection strength.

[0013] This side-grinding device for rearview mirror glass plates uses an upper and lower pressure block to press against the upper and lower surfaces of the rearview mirror glass plate, creating a surrounding negative pressure adsorption space in the grinding area. This collects debris directly from its source, preventing debris from splashing and polluting the environment and scratching the glass surface, thus reducing cleaning costs. Furthermore, the pressing force of the upper and lower pressure blocks acts on the rearview mirror glass plate, making the connection between the rearview mirror glass plate and the suction cup tighter and preventing the rearview mirror glass plate from detaching from the suction cup.

[0019] Please see Figure 1 This utility model provides a side grinding device for rearview mirror glass, including a grinding table 1, a movable block is movably arranged on the top of the grinding table 1, a rearview mirror glass plate 4 is adsorbed and connected to the top of the movable block, an electric slide rail 2 and an electric vertical rail 5 are fixedly connected to the top of the grinding table 1 respectively, the movable block is slidably installed on the electric slide rail 2, a suction cup 3 is fixedly connected to the top of the movable block, and the bottom of the rearview mirror glass plate 4 is adsorbed on the suction cup 3. In this embodiment, the suction cup 3 can be a common elastic suction cup 3. By pressing the rearview mirror glass plate 4, the rearview mirror glass plate 4 and the suction cup 3 can be attached together. Alternatively, the suction cup 3 can be an electric suction cup. The electric suction cup generates negative pressure by connecting to a power source to actively attach and fix the rearview mirror glass plate 4. Since this is existing technology, it will not be described in detail.

[0020] Please see Figure 2 and Figure 3The rearview mirror glass panel 4 is provided with a synchronously lifting grinding component and a pressing component on the side to be ground. The pressing component includes an upper pressing block 12 and a lower pressing block 15. The upper pressing block 12 and the lower pressing block 15 are relatively elastically pressed against the upper and lower surfaces of the rearview mirror glass panel 4, and the side of the rearview mirror glass panel 4 to be ground extends out of the upper pressing block 12 and the lower pressing block 15. The grinding component and the extended end of the rearview mirror glass panel 4 are in contact. The grinding component includes a grinding machine 8. An electric vertical rail 5 is slidably installed on the side near the moving block. An electric push rod is fixedly connected to one side of the lifting platform 7. A fixed frame 6 is fixedly connected to one end of the electric push rod. The grinding machine 8 is fixedly connected to the bottom end of the fixed frame 6.

[0021] In this embodiment, the grinding head of the grinding machine 8 is positioned towards the positioning and conveying assembly and is adapted to the side of the rearview mirror glass plate 4 to be ground. The electric push rod can drive the grinding machine 8 to approach the side of the rearview mirror glass plate 4 to be ground, so that the grinding head of the grinding machine 8 is always in close contact with the side of the rearview mirror glass plate 4 to be ground.

[0022] A connecting frame 10 is fixedly connected to the bottom of the fixed frame 6. Two first spring telescopic rods 11 are fixedly connected to the bottom of the connecting frame 10. The upper pressure block 12 is fixedly connected to the bottom of the two first spring telescopic rods 11. A second spring telescopic rod 14 is fixedly connected between the bottom of the lower pressure block 15 and the top of the grinding table 1. The lower pressure block 15 and the upper pressure block 12 are vertically aligned.

[0023] Please see Figure 2 and Figure 3 The upper pressure block 12 and the lower pressure block 15 are arranged opposite to each other to form a pressing space for pressing the rearview mirror glass plate 4. The upper pressure block 12 and the lower pressure block 15 have the same length, and the length of the upper pressure block 12 and the lower pressure block 15 is greater than the side length of the rearview mirror glass plate 4, to ensure full pressing of the polished side of the rearview mirror glass plate 4. The lower surface of the upper pressure block 12 and the upper surface of the lower pressure block 15 are both fixedly connected with elastic buffer pads. The elastic buffer pads are silicone pads or rubber pads, and their surfaces are provided with anti-slip textures to avoid damage to the surface of the rearview mirror glass plate 4 during pressing, while enhancing the pressing stability.

[0024] Please see Figure 3 , Figure 4 and Figure 5 A vacuum cleaner 13 is fixedly connected to the top of the connecting frame 10 and the grinding table 1. An adsorption groove 16 is opened on the side of the upper pressure block 12 and the lower pressure block 15 near the grinding machine 8. A pipe 9 is provided between the two adsorption grooves 16 and the corresponding vacuum cleaner 13. An adsorption hole 17 is opened on the opposite side of the lower pressure block 15 and the upper pressure block 12. The adsorption hole 17 is connected to the corresponding adsorption groove 16.

[0025] After the lower pressure block 15 and the upper pressure block 12 are clamped onto the rearview mirror glass plate 4, the vacuum cleaner 13 is turned on, and the suction hole 17 can generate suction force, which acts on the upper and lower surfaces of the rearview mirror glass plate 4 to enhance the connection strength.

[0026] It should be noted that the electric slide rail 2, electric vertical rail 5, electric push rod, grinder 8, and vacuum cleaner 13 are all existing products. The specific structure, electrical connection method (circuit layout), and working principle of the electric slide rail 2, electric vertical rail 5, electric push rod, grinder 8, and vacuum cleaner 13 are all existing publicly available technologies. At the same time, the electric slide rail 2, electric vertical rail 5, electric push rod, grinder 8, and vacuum cleaner 13 are all electrically connected to the controller, which is a PLC controller, used to realize the coordinated automated control of various components. The electric slide rail 2, electric vertical rail 5, electric push rod, grinder 8, and vacuum cleaner 13 can also be connected to the control button, and the electric slide rail 2, electric vertical rail 5, electric push rod, grinder 8, and vacuum cleaner 13 can be manually started to work through the control button.

[0027] Working principle: The rearview mirror glass plate 4 to be polished is placed on the suction cup 3, so that the rearview mirror glass plate 4 and the suction cup 3 are adsorbed and fixed. Then, the electric slide rail 2 is activated, so that the moving block moves the adsorbed rearview mirror glass plate 4 between the upper pressure block 12 and the lower pressure block 15. At this time, the electric vertical rail 5 is activated, so that the polishing component and the upper pressure block 12 are lowered at the same time. Since the polishing component and the upper pressure block 12 are at different heights, the upper pressure block 12 will contact the rearview mirror glass plate 4 first and generate downward pressure. Then, the polishing machine 8 is lowered and corresponds to the side of the rearview mirror glass plate 4. The upper pressure block 12 and the lower pressure block 15 are pressed tightly against the upper and lower surfaces of the side of the rearview mirror glass plate 4 to be polished by the elastic force of the first spring telescopic rod 11 and the second spring telescopic rod 14, so that the pressing force is concentrated on the polishing side, thereby reducing the vibration of the polishing side of the rearview mirror glass plate 4 during polishing.

[0028] At the same time, the pressing force of the upper pressing block 12 and the lower pressing block 15 can be applied to the rearview mirror glass plate 4, making the connection between the rearview mirror glass plate 4 and the suction cup 3 tighter and preventing the rearview mirror glass plate 4 and the suction cup 3 from separating. The upper pressure block 12 and the lower pressure block 15 have suction holes 17 on opposite sides. The suction holes 17 are connected to the corresponding suction grooves 16. When the vacuum cleaner 13 generates suction, it can adsorb the upper and lower surfaces of the rearview mirror glass plate 4 to enhance the connection strength.

[0029] Furthermore, during the polishing process, the two vacuum cleaners 13 are activated, and the dust generated during polishing can be collected by the suction grooves 16 on one side of the upper pressure block 12 and the lower pressure block 15. The suction grooves 16 of the upper pressure block 12 and the lower pressure block 15 can create suction space in the upper and lower areas of the polishing side, preventing dust from splashing up and down.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles of the present invention, the scope of which is defined by the appended claims and their equivalents.
