Description

Technical Field

[0001] The invention relates to the technical field of sapphire polishing, in particular to a polishing device for a 2.5D sapphire window screen. Background Art

[0002] Single crystal sapphire windows are ideal for demanding applications such as laser systems because they have high surface hardness, high thermal conductivity, high dielectric constant, and resistance to chemical acids and bases. Since sapphire is second only to diamond in hardness, its structural strength is very high.

[0003] The existing Chinese patent with the authorization announcement number CN109759907B discloses a polishing method for a 2.5D sapphire window screen, which includes the following steps: step A, polishing the square hole earpiece hole and polishing the round hole button hole, wherein the steps of polishing the square hole and polishing the round hole can be in any order, step B, polishing the front and bottom surfaces of the sapphire with a double-sided copper plate, step C, polishing the straight body of the 2.5D sapphire, step D, polishing the arc edge of the sapphire, and step E, polishing the sapphire edge including the arc edge, straight body and bottom chamfer of the sapphire with a four-sided polishing machine. The present invention changes the polishing method of the 2.5D glass screen, and by adopting certain process steps, the present invention obtains a 2.5D sapphire window screen product with qualified indicators. The method of the present invention reduces the roughness of the sapphire product and improves the brightness of the sapphire product, increases the aesthetics of the product, and greatly improves the yield and efficiency of product production. And the strength of the sapphire window screen product is doubled compared with the glass window screen.

DETAILED DESCRIPTION

[0034] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0035] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0037] Example 1

[0038] Reference Figure 1-Figure 9 , which is the first embodiment of the present invention, provides a 2.5D sapphire window screen polishing device, including a grinding mechanism 100, a limiting mechanism 200 and an adjusting mechanism 300. The arc edge polishing of the window screen 103 is achieved through the grinding mechanism 100 and the flip frame 303. At the same time, the suction hole 201 in the limiting mechanism 200 can automatically open and adsorb and fix as the window screen 103 is placed, and the non-contact suction hole 201 remains closed to prevent the polishing liquid from entering and causing blockage. At the same time, maintenance while working and rapid switching of polishing accuracy can be achieved.

[0039] Specifically, the grinding mechanism 100 includes a grinding frame 101 that is rotatably arranged, a polishing plate 102 arranged on the outer wall of the grinding frame 101, and a window screen 103 that is attached to the outer wall of the polishing plate 102. The other end surface of the window screen 103 is movably provided with a fixed plate 104, and the fixed plate 104 can rotate.

[0040] The limiting mechanism 200 includes a suction hole 201 disposed inside the fixing plate 104 and an air pipe 202 disposed on the end surface of the suction hole 201;

[0041] The adjusting mechanism 300 includes a rotating shaft 301 disposed on the end surface of the fixed disk 104 , a motor 302 sleeved on the outer wall of the rotating shaft 301 , and a turning frame 303 movably disposed on the outer wall of the motor 302 .

[0042] The grinding frame 101 is in the shape of a hexagonal prism, and polishing plates 102 are respectively arranged on the six outer walls. The polishing plates 102 are brush plates specially used for grinding and polishing sapphire window screens, and are movably arranged on the outer wall of the grinding frame 101 by bolts.

[0043] Preferably, the window screen 103 is a 2.5D sapphire window screen, the bottom surface of which is flat and the other surface is curved. The window screen 103 is fixed to the fixed plate 104 by suction through the air pipe 202 to generate negative pressure, and fits with the polishing plate 102.

[0044] Preferably, when the fixed disk 104 rotates, it drives the window screen 103 to rotate, and continuously contacts and rubs with the bristles on the surface of the polishing plate 102, thereby polishing the surface of the window screen 103. The flip frame 303 is a universal joint, so that the flip frame 303 can be deflected to various angles.

[0045] When the curved surface of the window screen 103 needs to be polished, the angle of the flip frame 303 is adjusted so that the curved surface of the window screen 103 contacts the polishing plate 102 and is polished. As the angle adjustment increases, the curved surface to be polished is closer to one end of the bottom surface, and the curved surface can be polished by adjusting the angle.

[0046] A piston 201a is slidably provided on the inner wall of the suction hole 201, a plug 201b is rotatably provided on the outer wall of the piston 201a, a baffle 201c is fixedly provided on the inner wall of the suction hole 201, and a sealing seat 201c-1 is provided on the outer wall of the baffle 201c.

[0047] Furthermore, a connecting rod 201a-1 is provided at one end of the piston 201a away from the plug 201b. The connecting rod 201a-1 slides through the baffle 201c and a first elastic member 201a-2 is provided on the outer wall of the connecting rod 201a-1.

[0048] The sealing seat 201c-1 has a truncated cone-shaped hole groove inside, and the outer wall of the connecting rod 201a-1 is also slidably sleeved with a sliding ball 201a-3, and the two ends of the first elastic member 201a-2 are respectively connected to the inner wall of the sliding ball 201a-3 and the baffle 201c.

[0049] More preferably, the first elastic member 201a-2 is a spring, which is fixedly connected to the sliding ball 201a-3. In the absence of external force, the first elastic member 201a-2 pushes the sliding ball 201a-3 to slide upward to the center position of the connecting rod 201a-1. After the sliding ball 201a-3 slides downward and fits against the inner wall of the sealing seat 201c-1, sealing can be achieved to prevent gas from passing through the suction hole 201.

[0050] Among them, the inner wall of the suction hole 201 is provided with a truncated cone-shaped step, the piston 201a is truncated cone-shaped, the piston 201a is movably engaged with the truncated cone-shaped step on the inner wall of the suction hole 201, the plug 201b can slide along the inner wall of the suction hole 201, and the outer wall of the fixed plate 104 and the outer wall of the plug 201b are provided with rubber buffer pads to prevent the polished window screen 103 surface from being scratched.

[0051] Preferably, a rotating column 201d is provided on the lower end surface of the connecting rod 201a-1, and the rotating column 201d is also rotatably provided on the inner wall of the suction hole 201. A sliding block 201d-1 is provided on the inner wall of the suction hole 201, and a sliding groove 201d-2 is provided on the outer wall of the rotating column 201d.

[0052] The slider 201d-1 is slidably disposed on the inner wall of the slide groove 201d-2, and an air groove 201d-3 is also opened on the outer wall of the rotating column 201d.

[0053] More preferably, the rotating column 201d is cylindrical and completely fits the inner wall of the suction hole 201. In the initial state, the air groove 201d-3 is a linear groove and does not contact the port of the air pipe 202. Therefore, the air groove 201d-3 is not connected to the air pipe 202 in the initial state.

[0054] In summary, when in use, the staff first adjusts the fixed disk 104 to a horizontal state, and then sets the bottom surface of the window screen 103 to be polished on the end surface of the fixed disk 104. Due to the weight of the window screen 103 itself, the plug 201b higher than the end surface of the fixed disk 104 is pushed to slide downward, and at the same time, the plug 201b slides downward to drive the piston 201a to move downward and away from the truncated cone-shaped step, so that the suction hole 201 is released from sealing, while the suction hole 201 that is not in contact with the fixed disk 104 is still blocked, preventing air leakage and cutting fluid from entering the suction hole 201 to cause blockage;

[0055] At the same time, the piston 201a moves downward and squeezes the rotating column 201d downward through the connecting rod 201a-1. Since the connecting rod 201a-1 and the rotating column 201d are rotatably connected and the slide groove 201d-2 is a spiral slide groove, the rotating column 201d-1 will also rotate while moving downward. As the rotating column 201d rotates, the air groove 201d-3 rotates to contact the air pipe 202, and the airway is connected, thereby forming a negative pressure, fixing the window screen 103, and then polishing and adjusting the angle. At the same time, the grinding frame 101 itself can quickly rotate to the connected grid, so as to achieve a rapid renewal of the precision of the polishing plate 102, and realize normal operation on one side and replacement of the polishing plate 102 on the other side, and the rapid switching of the polishing precision increasing or decreasing in sequence, thereby simplifying the workflow.

[0056] Example 2

[0057] Reference Figure 1-Figure 7 , which is the second embodiment of the present invention. This embodiment is based on the previous embodiment, but is different in that the adsorption force is automatically adjusted according to the weight of the window screen 103 to avoid scratches. At the same time, the flow rate and start-up of the polishing liquid are automatically adjusted according to the polishing speed. The polishing liquid is sprayed evenly from all sides, and the polishing liquid automatically flows away when it is used up to prevent blockage.

[0058] Specifically, a pressure needle 301d - 4 is provided at the bottom of the rotating column 201d , and a pressure-sensitive sensor is movably engaged with the end surface of the pressure needle 301d - 4 , and the pressure-sensitive sensor controls the internal pressure of the air pipe 202 .

[0059] Among them, the window screen 103 itself has different weights, so the downward pressing distance of the pressure needle 301d-4 changes accordingly. The pressure change inside the air pipe 202 is controlled by the pressure-sensitive sensor, so that different adsorption forces are adopted for window screens 103 of different weights to prevent defects such as scratches caused by excessive force.

[0060] A disc 301a is provided on the outer wall of the rotating shaft 301, a swing block 301a-1 is rotatably provided on the end surface of the disc 301a, a shell 301a-2 is rotatably provided on the outer wall of the rotating shaft 301, and a ratchet 301a-3 is provided on the inner wall of the shell 301a-2.

[0061] More preferably, a liquid pump 301b is rotatably provided on the end surface of the shell 301a-2, a liquid inlet pipe 301b-1 is provided on the end surface of the liquid pump 301b, a flow channel 301c is provided on the inner wall of the rotating shaft 301, and polishing liquid is provided inside the flow channel 301c.

[0062] Furthermore, the disk 301a is fixed on the outer wall of the rotating shaft 301 and rotates therewith, and the swing block 301a-1 is rotatably arranged on the end face of the disk 301a. A clockwork spring is arranged between the swing block 301a-1 and the disk 301a, so that in the initial state, the swing block 301a-1 retracts into the inside of the disk 301a.

[0063] Among them, the direction of the ratchet 301a-3 is the same as the rotation direction of the shaft 301. When the swing block 301a-1 retracts, the swing block 301a-1 does not contact the ratchet 301a-3. The motor 302 starts, driving the disc 301a to rotate. At the same time, the swing block 301a-1 is swung outward by the centrifugal force and contacts the ratchet 301a-3.

[0064] More preferably, the housing 301a-2 is rotatably arranged through a bearing seat, and when the swing block 301a-1 drives the housing 301a-2 to rotate, the liquid pump 301b connected thereto is driven to squeeze the polishing liquid into the flow channel 301c.

[0065] Preferably, the other end of the flow channel 301c passes through the inner wall of the suction hole 201 and is provided with a nozzle 301c-1, and the plug 201b is pressed downward by the window screen 103 and slides to fit with the nozzle 301c-1.

[0066] Among them, the plug 201b that is not in contact with the window screen 103 does not change, so that the polishing liquid can be sprayed from the surroundings to the center. After the plug 201b blocks the nozzle 301c-1, the polishing liquid can only be sprayed from other nozzles 301c-1, thereby realizing automatic adjustment of the polishing liquid range.

[0067] In summary, when in use, the weight of the window screen 103 affects the downward pressing distance of the pressure needle 301d-4, so that the negative pressure is controlled by the pressure-sensitive sensor to achieve adaptive adjustment of the adsorption force; at the same time, when the polishing device is running, the motor 302 is started, and the rotating shaft 301 is driven to rotate through the output shaft, and at the same time, the swing block 301a-1 located on the disc 301a swings due to the centrifugal force and contacts and fits with the ratchet 301a-3, thereby driving the shell 301a-2 to rotate, and finally the polishing liquid is pumped into the flow channel 301c through the liquid pump 301b, thereby achieving automatic start and stop of the polishing liquid, and automatically adjusting the flow rate of the polishing liquid according to the polishing speed;

[0068] At the same time, the internal plug 201b of the suction hole 201 in contact with the window screen 103 is pressed downward and blocks the nozzle 301c-1, and the internal plug 201b of the suction hole 201 not in contact with the window screen 103 does not block the nozzle 301c-1, thereby realizing automatic adjustment of the polishing liquid spraying area, and the suction holes 201 surrounding the window screen 103 evenly spray the polishing liquid onto the window screen 103. At the same time, because the fixed plate 104 is tilted, the used polishing liquid will automatically flow away with the frosted particles to prevent accumulation.

[0069] Example 3

[0070] Reference Figure 1-Figure 9 , which is the third embodiment of the present invention, is based on the previous embodiment, except that the deflection of the window screen 103 in each direction is controlled by three swing arms 303a, and at the same time, the polishing of the arc edge surface of the window screen 103 is achieved under the support and limitation of the universal joint 302a-1.

[0071] Specifically, the end surface of the motor 302 is fixedly provided with an offset plate 302a, the other end surface of the offset plate 302a is provided with a universal joint 302a-1, the other end of the universal joint 302a-1 is provided with a base column 302a-2, and the flip frame 303 is rotatably provided on the outer wall of the offset plate 302a.

[0072] The flip frame 303 includes a swing arm 303a, a rotating sleeve 303b disposed on the end surface of the swing arm 303a, and a driven gear 303b-1 connected to the rotating sleeve 303b. The outer wall of the driven gear 303b-1 is meshed with a driving gear 303c.

[0073] Furthermore, a plate 302a-3 is fixedly provided on the outer wall of the base column 302a-2, and a driving shaft 303c-1 is provided on the end surface of the driving gear 303c. The driving shaft 303c-1 passes through the plate 302a-3 and is provided with a handle 303c-2.

[0074] There are three sets of flip frames 303 , and the circular array is arranged on the outer wall of the offset plate 302 a . The universal joint 302 a - 1 enables the offset plate 302 a to drive the fixed disk 104 to rotate around the center of the circle, thereby achieving polishing of the edge area of ​​the window screen 103 .

[0075] More preferably, the rotating sleeves 303b are arranged alternately on the outer wall of the base column 302a-2, and the rotating sleeves 303b are slidably connected to each other, so that the three rotating sleeves 303b can rotate independently.

[0076] Among them, the swing arm 303a is formed by rotating and splicing several folding rods. As the rotating sleeve 303b drives the swing arm 303a to rotate, the offset plate 302a rotatably connected to the swing arm 303a is flipped downward. At the same time, the offset plate 302a itself is limited by other swing arms 303a, thereby driving the offset plate 302a to flip as a whole, driving the motor 302, the fixed disk 104 and the window screen 103 to flip, thereby polishing the edges of different areas of the window screen 103.

[0077] In summary, when in use, firstly, the offset plate 302a is made parallel to the polishing plate 102 to polish the bottom surface and the flat area on the front surface of the window screen 103, and then the handle 303c-2 is rotated to drive the driving shaft 303c-1 to rotate, and the driving gear 303c connected to the driving shaft 303c-1 rotates, driving the driven gear 303b-1 meshed with it to rotate, and then the swing arm 303a is driven to rotate by the rotating sleeve 303b connected to the driven gear 303b-1, so that as the swing arm 303a swings, the offset plate 303a connected thereto is driven to rotate. 2a is flipped up and down, and at the same time, the other swing arms 303a connected thereto rotate among the various folding rods, so that the offset plate 302a is tilted as a whole, and at the same time, the center of the window screen 103 is supported and limited by the universal joint 302a-1, and the window screen 103 is flipped around the center of the circle at a certain angle, so that when the window screen 103 is rotated, only the outermost area is in contact with the polishing plate 102 and polished without affecting the rotation of the window screen 103. With the adjustment of the rotation angle of the window screen 103, the polishing of the arc-shaped edge surface of the window screen 103 can be achieved.
