Description

Technical Field

[0001] This application belongs to the field of glass processing technology, specifically relating to a cover glass liquid polishing device. Background Technology

[0002] In industrial production, liquid polishing is an important surface treatment method widely used in the processing of various workpieces, effectively improving the surface finish, precision, and overall quality of the workpieces. The liquid polishing frame, as a key supporting component in the liquid polishing process, bears the important responsibility of stably supporting the workpieces to be processed. Its structural stability and performance directly affect the processing effect, production stability, and final product yield of the liquid polishing process. However, the current liquid polishing frames suffer from significantly reduced bending and deformation resistance due to excessively long support rods. During the liquid polishing process, the support rods must withstand the weight of the workpiece and various forces generated during processing. Furthermore, the liquid polishing frames require frequent movement, making them highly susceptible to severe bending and deformation under these forces. This deformation not only changes the position and orientation of the workpiece to be processed, leading to unstable processing parameters and affecting processing accuracy, but also severely damages the stability of the entire liquid polishing process, resulting in a large number of defective products and significantly reducing the production yield. Utility Model Content To address the shortcomings of the prior art, this application provides a cover glass liquid polishing device. By improving the structural design of the placement mechanism, the overall rigidity of the placement mechanism is enhanced, thereby increasing its bending resistance and deformation resistance, ensuring the stability of the liquid polishing process, and effectively improving the production yield.

[0003] The technical effects to be achieved in this application are realized through the following aspects: This application provides a cover glass liquid polishing device, including a loading mechanism for loading cover glass to be processed; The storage mechanism includes oppositely arranged side plates, several supporting members, several limiting parts, and partitions; The limiting part is connected between the side plates and is located at the four corners of the side plates to limit the edge of the cover glass; The support member is connected between the side plates and is located on both sides of the lower end of the side plate below the limiting part, for supporting the bottom of the cover glass; The partition is disposed between the side plates and is parallel to the side plates, and passes through the support member and the limiting part; With the vertical central axis of the side plate as the center, adjacent support members are symmetrically arranged in the horizontal direction, adjacent limiting parts are symmetrically arranged, and the distance between adjacent support members is less than the distance between adjacent limiting parts.

[0004] In some implementations, the limiting part includes a body and a plurality of locking blocks, the locking blocks being evenly spaced and fitted onto the body, and the locking blocks having locking grooves for placing and limiting the edges of the cover glass.

[0005] In some implementations, the lower end of the partition is provided with a groove.

[0006] In some implementations, the placement mechanism further includes several reinforcing rods connected between the side plates and disposed between adjacent limiting parts; the central axis of the reinforcing rods is arranged parallel to the central axis of the limiting part.

[0007] In some implementations, the upper end of the side plate is provided with a hanging part, which is detachably connected to the drive component.

[0008] Some implementations also include a liquid slinging mechanism and a drive mechanism; The liquid polishing mechanism includes a first liquid polishing tank and a second liquid polishing tank arranged side by side. The bottom of the first liquid polishing tank is provided with a first support part, and the bottom of the second liquid polishing tank is provided with a second support part. The first support part and the second support part are separated by a first distance in the vertical direction. The first support part and the second support part are used to support the bottom of the cover glass. The drive mechanism is located on one side of the liquid polishing mechanism and is used to control the movement of the placement mechanism between the first liquid polishing tank and the second liquid polishing tank, so that the cover glass in the placement mechanism is alternately liquid polished between the first liquid polishing tank and the second liquid polishing tank.

[0009] In some implementations, the first distance is any value between 10mm and 30mm.

[0010] In some implementations, the support member is misaligned with the first support portion and the second support portion.

[0011] In some implementations, the drive mechanism includes columns, beams, and actuating components arranged symmetrically on both sides; The two ends of the crossbeam are movably connected to the column, which is used to drive the actuator to achieve longitudinal movement; the actuator is movably connected to the crossbeam, which is used to drive the actuator to achieve lateral movement.

[0012] In some implementations, the upper end of the side plate is provided with a hanging part; the actuating component is provided with a lifting part, which is adapted to the hanging part.

[0013] In summary, this application has at least the following advantages: The cover glass liquid polishing device provided in this application effectively shortens the length of the support and limiting parts by adding a partition between the side plates, thereby effectively improving the rigidity of the overall structure and greatly enhancing its bending resistance and deformation resistance. This ensures the stability of the liquid polishing process even during frequent movement of the placement mechanism, effectively improving production yield. Furthermore, by supporting the bottom of the cover glass and limiting the edge of the cover glass by the support, the device not only effectively ensures the placement stability of the cover glass but also enables the batch placement of cover glass.

[0022] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. The described embodiments are only some embodiments of this application, not all embodiments.

[0023] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0024] Example 1: Please see the appendix Figure 1 The cover glass liquid polishing device of this application includes a placement mechanism 2 for loading cover glass 4 to be processed; the placement mechanism 2 includes side plates 21 arranged opposite each other, a plurality of support members 22, a plurality of limiting parts 23 and partitions 24; the limiting parts 23 are connected between the side plates 21 and are located at the four corners of the side plates 21; the support members 22 are connected between the side plates 21 and are located on both sides of the lower end of the side plates 21 corresponding to the lower part of the limiting part 23; the partitions 24 are located between the side plates 21 and are arranged parallel to the side plates 21, and pass through the support members 22 and the limiting parts 23; in the horizontal direction, with the central axis of the side plate 21 as the center, the adjacent support members 22 are symmetrically arranged, the adjacent limiting parts 23 are symmetrically arranged, and the distance between adjacent support members 22 is less than the distance between adjacent limiting parts 23.

[0025] Preferably, there are two support members 22. There are four limiting parts 23. There are two side plates 21.

[0026] In this embodiment, the partition 24 of the storage mechanism 2 divides the limiting part 23 and the support member 22 into two parts, effectively shortening the length of the limiting part 23 and the support member 22, effectively improving the bending and deformation resistance of the limiting part 23 and the support member 22, avoiding the phenomenon of the cover glass 4 being squeezed and deformed in the storage mechanism 2, further improving the structural stability of the storage mechanism 2, and effectively improving the liquid polishing yield of the cover glass 4.

[0027] In addition, a support member 22 is used to support the bottom of the cover glass 4, and a limiting part 23 is used to restrict and fix the upper and lower edges of the glass to ensure the stability of the cover glass 4. The support member 22 and the limiting part 23 are also fixed on both sides by the side plate 21 to ensure the overall structural integrity. This arrangement allows the cover glass 4 to be stably placed between the support member 22 and the limiting part 23, facilitating the drive mechanism 3 to move several cover glass pieces 4 from the placement mechanism 2 back and forth into the first liquid polishing tank 11 and the second liquid polishing tank 12, ensuring the smoothness of the entire liquid polishing process.

[0028] In some embodiments, see Figure 2 The limiting part 23 includes a main body 231 and a plurality of locking blocks 232. The locking blocks 232 are evenly spaced and fitted onto the main body 231. Each locking block 232 has a locking groove 233, which is used to place and limit the edge of the cover glass 4. Preferably, the locking groove 233 is an outward-facing octagonal locking groove 233, that is, the distance between the two edges of the end of the locking groove 233 closer to the main body 231 is smaller than the distance between the two edges of the end of the locking groove 233 farther from the main body 231. This arrangement facilitates the entry of the cover glass 4 into the locking groove 233, improves placement convenience, and is conducive to automated batch placement.

[0029] Specifically, the edge of the cover glass 4 is placed within the slot 233. Since the limiting part 23 is located at the four corners of the side plate 21, it limits the four diagonal positions of the cover glass 4, ensuring the stability of the cover glass 4. Furthermore, the evenly spaced slots 232 ensure a safe gap between adjacent cover glass 4, preventing the cover glass 4 from getting too close and affecting the liquid polishing efficiency, while also ensuring the safety of the cover glass 4 during movement.

[0030] In some embodiments, please refer to Figure 3 The lower end of the partition 24 is provided with a groove 241. Through this setting, the groove 241 has the function of limiting and fixing. During the liquid polishing process, the placement mechanism 2 is placed in the liquid polishing tank for etching operation by the drive mechanism 3, and the groove 241 is matched with the limiting part in the liquid polishing tank that is adapted to the groove 241, thereby ensuring that the placement mechanism 2 is stably placed in the liquid polishing tank, thereby ensuring the processing quality of the cover glass 4.

[0031] In some preferred embodiments, the lower end of the side plate 21 is also provided with a groove 241. The groove 241 at the lower end of the side plate 21 and the groove 241 at the lower end of the partition plate 24 have the same function, further ensuring the stability of the placement mechanism 2 when placed in the liquid slurry tank.

[0032] In some embodiments, the storage mechanism 2 further includes a plurality of reinforcing rods 25, which are connected between the side plates 21 and disposed between adjacent limiting portions 23; the central axis of the reinforcing rods 25 is parallel to the central axis of the limiting portion 23. This arrangement makes the overall structure more rigid and stable, preventing the fastening bolts in the storage mechanism 2 from loosening in a high-temperature and strong alkaline environment, thus preventing the liquid polishing frame from twisting and deforming, and effectively improving the overall stability and firmness of the storage mechanism 2.

[0033] In some embodiments, the upper end of the side plate 21 is provided with a hanging part 211, which is detachably connected to the drive component. Preferably, the hanging part 211 is hook-shaped. This arrangement effectively improves the ease of lifting and placing the storage mechanism 2 by the drive mechanism 3, ensuring smooth and rapid movement of the storage mechanism 2.

[0034] Example 2: The difference between this embodiment and Embodiment 1 is that, please refer to... Figures 4-6 The cover glass 4 liquid polishing device in this embodiment also includes a liquid polishing mechanism 1 and a driving mechanism 3.

[0035] The liquid polishing mechanism 1 includes a first liquid polishing tank 11 and a second liquid polishing tank 12 arranged side by side. The bottom of the first liquid polishing tank 11 is provided with a first support part 111, and the bottom of the second liquid polishing tank 12 is provided with a second support part 112. The first support part 111 and the second support part 112 are separated by a first distance in the vertical direction. The first support part 111 and the second support part 112 are used to support the bottom of the cover glass 4. The placement mechanism 2 is used to load the cover glass 4 to be processed. The placement mechanism 2 is placed in the first liquid polishing tank 11 or the second liquid polishing tank 12. The drive mechanism 3 is provided on one side of the liquid polishing mechanism 1 and is used to control the movement of the placement mechanism 2 between the first liquid polishing tank 11 and the second liquid polishing tank 12 so that the cover glass 4 in the placement mechanism 2 is alternately liquid polished between the first liquid polishing tank 11 and the second liquid polishing tank 12.

[0036] The first liquid polishing tank 11 and the second liquid polishing tank 12 are used to hold etching liquid and etch the cover glass 4. The height of the first support 111 is lower than the height of the second support 112. The drive mechanism 3 can specifically adopt a gantry-type moving mechanism, that is, the crossbeam is supported by columns or guide rails on both sides. The crossbeam can move along the direction of the columns to achieve longitudinal movement, while the actuator on the crossbeam can move along the direction of the crossbeam to achieve lateral movement, forming a three-dimensional moving mode similar to a "gantry" frame structure. It is understood that the actuator can specifically adopt a slider, a robotic arm, etc., to lift the placement mechanism 2, as long as it matches the structure of the placement mechanism 2. In addition, the actuator is provided with a lifting part adapted to the hanging part 211, so that the actuator can quickly lift and lower the placement mechanism 2, ensuring smooth movement.

[0037] In this embodiment, the cover glass 4 liquid polishing device has the following overall liquid polishing process: First, the cover glass 4 is placed in the placement mechanism 2, and then the placement mechanism 2 is moved above the first liquid polishing pool 11 by the driving mechanism 3, and the placement mechanism 2 is placed at the bottom of the first liquid polishing pool 11, so that the first support part 111 supports the cover glass 4 in the placement mechanism 2, so that the cover glass 4 can be liquid polished in the first liquid polishing pool 11. After a period of time, the drive mechanism 3 moves the placement mechanism 2 from the first liquid polishing tank 11 to the second liquid polishing tank 12, so that the bottom of the cover glass 4 in the placement mechanism 2 is supported by the second support part 112. Since the first support part 111 and the second support part 112 are separated by a first distance in the vertical direction, and the height of the second support part 112 is set to be greater than the height of the first support part 111, the cover glass 4 moves upward, thereby changing the support position between the cover glass 4 and the placement mechanism 2. After the cover glass 4 is etched in the second liquid polishing tank 12 for a period of time, the placement mechanism 2 is placed in the first liquid polishing tank 11 and the second liquid polishing tank 12 in sequence for liquid polishing until the wire feed amount designed for the product is reached, and the liquid polishing ends.

[0038] Through the above technical solution, the drive mechanism 3 uses the placement mechanism 2, which is filled with cover glass 4, to perform liquid polishing back and forth in the first liquid polishing tank 11 and the second liquid polishing tank 12. Due to the height difference between the first support part 111 and the second support part 112, the cover glass 4 can be lifted back and forth in the first liquid polishing tank 11 and the second liquid polishing tank 12. As a result, the cover glass 4 passively slides up and down in the placement mechanism 2. During this process, the contact point between the glass and the placement mechanism 2 can fully react, avoiding the phenomenon of uneven liquid polishing caused by delayed chemical reaction process. It effectively removes the marks of contact with the placement mechanism 2 and ensures the uniformity of liquid polishing. Moreover, compared with dynamic liquid polishing, the liquid polishing process of this device greatly reduces the frequency of up and down movement of the cover glass 4 in the support position of the placement mechanism 2, reduces the number of frictions and the number of impacts when the glass is lifted by the low rod, and thus effectively reduces the defects of glass edge scratches and dents after liquid polishing, ensuring the liquid polishing processing quality of the cover glass 4 and effectively improving the production yield of the cover glass 4.

[0039] In this structure, a liquid polishing device is used to polish the cover glass 4 in a liquid polishing tank. The overall operation process is simple and easy to learn, and the structural design is simple and conducive to subsequent maintenance.

[0040] In some preferred embodiments, the first distance is any value between 10mm and 30mm. This setting allows the cover glass 4 to move dynamically during the alternating liquid polishing process in the first liquid polishing tank 11 and the second liquid polishing tank 12. This distance ensures that the contact point between the cover glass 4 and the placement mechanism 2 is in full contact with the etching solution, achieving uniform liquid polishing. Simultaneously, it prevents excessive movement and instability of the cover glass 4, effectively ensuring its placement stability and guaranteeing smooth liquid polishing operations.

[0041] In some embodiments, the support member 22 and the first support portion 111 and the second support portion 112 are staggered so that when the placement mechanism 2 is placed in the first liquid polishing tank 11 and the second liquid polishing tank 12, the first support portion 111 and the second support portion 112 replace the support member 22 and provide support for the cover glass 4.

[0042] Example 3: This embodiment is based on the above embodiment; please refer to [link / reference]. Figure 7 A method for liquid polishing cover glass 4 is provided, employing the aforementioned cover glass 4 liquid polishing apparatus, the steps of which include: S1: Load the cover glass 4 to be processed onto the storage mechanism 2; S2: Move the placement mechanism 2 into the first liquid polishing tank 11 through the drive mechanism 3, so that the bottom of the cover glass 4 is in close contact with the first support part 111, inject NaOH solution into the first liquid polishing tank 11, and set the initial liquid polishing parameters. S3: After the initial liquid polishing is completed, the placement mechanism 2 is moved to the second liquid polishing tank 12 by the drive mechanism 3, so that the bottom of the cover glass 4 is in close contact with the second support part 112. NaOH solution is continued to be injected into the second liquid polishing tank 12, and the same liquid polishing parameters as the first liquid polishing tank 11 are maintained. S4: Repeat S2 and S3 at least once; S5: Complete the liquid polishing process, move the placement mechanism 2 out of the liquid polishing mechanism 1 through the drive mechanism 3, and perform subsequent cleaning and drying treatment on the cover glass 4.

[0043] In some embodiments, the liquid polishing parameters include the concentration of the NaOH solution, the temperature, and the liquid polishing time.

[0044] In this embodiment, the liquid polishing method for the cover glass 4 involves setting the liquid polishing parameters in steps S2 to S4 to a NaOH solution concentration greater than 50% and a temperature above 100 degrees Celsius. If the total etching time is 2000 seconds, it is divided into four segments: first, the cover glass enters the first liquid polishing tank 11 for 500 seconds of etching; then, the drive mechanism 3 pulls out the placement mechanism 2 into the second liquid polishing tank 12 for another 500 seconds of etching; subsequently, the placement mechanism 2 re-enters the first liquid polishing tank 11 for 500 seconds; and finally, it enters the second liquid polishing tank 12 for 500 seconds, after which the chemical etching ends. The etching time can be flexibly determined based on the specific etching state. For example, if the cover glass 4 is statically in the liquid polishing tank, and after 500 seconds the shelf mark is visible, but after 400 seconds the etching mark is no longer visible, then each segment can be set to less than or equal to 400 seconds, and the segments can be divided according to the total time. In S5, cleaning involves removing the strong alkali. This can be done by immersing the cover glass in a clean water tank, using multiple tanks and soaking each tank for approximately 3 minutes to achieve a thorough cleaning. Drying can be achieved by air drying.

[0045] Through the above technical solution, the overall liquid polishing process is simple and non-redundant, with strong cycle time, which not only achieves high liquid polishing efficiency, but also ensures the liquid polishing processing quality of cover glass 4, and greatly improves the production yield of cover glass 4.
