TECHNICAL FIELD

[0001] The present application relates to the technical field of coating substrate grinding, in particular to a coating substrate material grinding device and grinding process. BACKGROUND

[0002] Coating substrate material is the core basic material supporting the coating process and bearing the thin film structure, its performance directly determines the adhesion, stability and final use effect of the thin film, and is widely used in the coating demand of electronic information, optics, aerospace and other fields. It is often divided into four categories according to material characteristics: metal, oxide, compound and special composite. Each type of material has its own characteristics in performance, process adaptability and application scenario. For example, silicon dioxide, aluminum oxide and zirconium oxide belong to oxide substrate material. They have outstanding high temperature resistance and electrical insulation, strong resistance to environmental factors such as moisture and oxidation, and excellent dielectric properties, which are commonly used in optical and electronic fields. For example, silicon dioxide substrate can be used for antireflection film bearing of optical glass, and aluminum oxide substrate is suitable for insulating film coating related to LED chip heat dissipation packaging.

[0003] The grinding requirement of substrate material for optical coating is very high. First, the shape is determined by rough grinding, and then wet fine grinding is performed to reduce surface scratches. Finally, polishing treatment is performed to reduce the surface roughness of the coating substrate material to the nanometer level, meeting the requirements of optical coating for light transmission and reflectivity. For example, the glass substrate of a camera lens needs to be ground and polished several times to ensure stable optical performance after coating.

[0004] When the optical coating substrate material is ground and processed, a grinding and polishing machine is generally used for processing. The grinding and polishing machine in the prior art mainly consists of a spindle, a spindle motor connected to the spindle for driving the spindle to rotate, and a ball mill mounted on the spindle. A swing frame is also provided on the body of the polishing machine, and a swing rod is fixedly provided on the swing frame. An iron pen is provided at the end of the swing rod. The iron pen on the swing rod is tightly pressed on the upper die by the air cylinder, so that the optical lens mounted on the die is ground on the ball mill. The cam mechanism is used to adjust the swing angle of the iron pen on the swing frame. For example, the patent CN111745500B discloses a center point assembly for an optical grinding and polishing machine and an optical grinding and polishing machine, and the patent CN212240412U discloses an optical grinding and polishing machine with a swing rod device. In order to improve the stress condition of the workpiece during grinding and obtain a product with better quality, the angle between the iron pen and the ball mill is always kept at 90 degrees, but the structure is complex. In the grinding process of the prior art, the iron pen and the coating substrate are connected only by pressure, the rotation of the clamp and the coating substrate cannot be effectively limited, and the rotation of the coating substrate on the side of the ball mill reduces the grinding effect and efficiency. If the coating substrate does not rotate, the uniformity and quality of the grinding will be reduced. SUMMARY

DETAILED DESCRIPTION

[0045] The present application will be further described below. It should be understood that the specific examples described herein are intended to explain the present application and are not intended to limit the present application, i.e., the described examples are only a part of the embodiments of the present application, but not all the embodiments.

[0046] The specific embodiments of the coating film substrate material grinding device and grinding process provided by the present application are as follows:

[0047] Please refer to Figures 1-12 , the coating film substrate material grinding device comprises a machine box 13, a clamp 3, a ball mill 4, an iron pen 1, a mounting frame 2, a crank rocker mechanism, a clutch and an arc-shaped support 8. A driving motor and a controller are arranged inside the machine box 13, and the machine box 13 protects the internal equipment and supports the upper side grinding structure.

[0048] The clamp 3 clamps the coated substrate, in this embodiment, the coated substrate is an optical lens 39, and the coated substrate is located at the lower side of the clamp 3. The ball mill 4 is supported at the lower side of the coated substrate, and the ball mill 4 rotates to grind the coated substrate. The upper part of the cabinet 13 is provided with a pot-shaped grinding liquid container 15, the lower part of the grinding liquid container 15 is embedded in the cabinet 13, the lower side of the ball mill 4 is connected with a main shaft 16, the main shaft 16 rotates through the bottom of the grinding liquid container 15, and the lower end extends into the cabinet 13, and the cabinet 13 is provided with a motor for driving the main shaft 16 to rotate.

[0049] The cabinet 13 is provided with a liquid supply pipe 17, and the outlet of the liquid supply pipe 17 sprays the grinding liquid to the outside of the ball mill 4, which assists the grinding and reduces the temperature of the grinding surface. The lower part of the grinding liquid container 15 is connected with a liquid discharge pipe. The cabinet 13 is provided with a device for outputting the grinding liquid and a container for collecting the used grinding liquid. In other embodiments, a grinding liquid circulating device can be provided, and a grinding liquid purification device can be configured.

[0050] The iron pen 1 is connected to the upper side of the clamp 3, and the connection structure of the iron pen 1 and the clamp 3 is improved in this embodiment, so that the iron pen 1 can drive the clamp 3 to move reciprocally on the upper side of the ball mill 4, and the rotation of the clamp 3 is limited. Specifically, the upper side of the clamp 3 is provided with a semispherical concave surface, a plurality of arc-shaped grooves 36 are uniformly distributed around the semispherical concave surface, the centers of all the arc-shaped grooves 36 intersect, the lower end of the iron pen 1 is provided with a semispherical convex surface, a plurality of arc-shaped strips 37 are uniformly distributed around the semispherical convex surface, and the centers of all the arc-shaped strips 37 intersect.

[0051] The semispherical concave surface with the arc-shaped grooves 36 forms a semispherical spline groove on the upper side of the clamp 3, and the semispherical convex surface with the arc-shaped strips 37 forms a semispherical spline on the lower end of the iron pen 1. The semispherical spline and the semispherical spline groove cooperate to enable the iron pen 1 and the clamp 3 to be linked, limit the rotation of the clamp 3 on the upper side of the ball mill 4, and thus provide conditions for the rotation control of the clamp 3. The radius of the semispherical convex surface at the lower end of the iron pen 1 is smaller than the radius of the semispherical concave surface of the clamp 3, so that the iron pen 1 and the clamp 3 have a certain angular deflection activity, avoiding the influence of hard connection on floating grinding, and not affecting the floating fit between the coated substrate and the ball mill 4, and ensuring the grinding quality.

[0052] The semispherical spline makes the connection activity strong, but is not conducive to the stability of the reciprocating movement of the iron pen 1 driving the clamp 3, therefore, the upper side of the clamp 3 is provided with a sunken groove 35, the sunken groove 35 is a cylindrical groove, the semispherical concave surface is located at the bottom of the sunken groove 35, the outer side of the iron pen 1 is provided with a plurality of rubber sheets 38 corresponding to the upper part of the sunken groove 35, the rubber sheets 38 are annular in shape, the outer edge of the rubber sheet 38 abuts against the inner side of the circumference of the sunken groove 35, the iron pen 1 applies a horizontal force to the clamp 3 through the rubber sheet 38 to drive the clamp 3 to move on the upper side of the ball mill 4, and at the same time, the rubber sheet 38 can be flexibly deformed to provide a floating grinding buffer.

[0053] The function of the rubber sheet 38 also enables the iron pen 1 to be perpendicular or close to perpendicular to the surface of the ball mill 4 when the clamp 3 is moved back and forth, so that the plated film substrate is subjected to force as evenly as possible in all directions and all positions, thereby ensuring the grinding and polishing effect. The lower end of the iron pen 1 can be quickly inserted and pulled out in the sink 35, without affecting the convenience of loading and unloading the clamp 3 and the plated film substrate, thereby ensuring a high grinding efficiency.

[0054] The mounting frame 2 supports the iron pen 1, and is a horizontal frame structure. The mounting frame 2 is provided with a through hole 33 at the front end, and the upper part of the iron pen 1 passes through the through hole 33, so that the height of the iron pen 1 can be adjusted to adapt to the plated film substrate and the clamp 3 of different thicknesses. The mounting frame 2 is provided with a fastening bolt 34 at the front end through threaded connection. The inner end of the fastening bolt 34 extends out of the through hole 33 and abuts against the outer side of the upper part of the iron pen 1, thereby achieving the positioning of the iron pen 1.

[0055] The upper side of the ball mill 4 is a part of a spherical surface. The reciprocating movement track of the clamp 3 on the upper side of the ball mill 4 is a circular arc. In order to enable the iron pen 1 to be perpendicular or close to perpendicular to the surface of the ball mill 4 when the clamp 3 is moved back and forth on the surface of the ball mill 4, the present embodiment ingeniously uses a crank rocker mechanism to easily achieve this effect. The crank rocker mechanism drives the mounting frame 2 to move back and forth in an arc line. During the reciprocating movement of the mounting frame 2 with the crank rocker mechanism, the mounting frame 2 can automatically change the angle, thereby driving the iron pen 1 to change the inclination angle, and always being perpendicular or close to perpendicular to the surface of the ball mill 4.

[0056] The crank rocker mechanism includes a driven gear 26, a swing frame 25 and a connecting rod 27. The two ends of the connecting rod 27 are respectively hinged to the upper part of the swing frame 25 and the edge of the driven gear 26. When the driven gear 26 rotates, the swing frame 25 reciprocates through the connecting rod 27. The rear end of the mounting frame 2 is connected to the swing frame 25. The swing frame 25 drives the mounting frame 2 and the iron pen 1 to move back and forth in an arc line. The perpendicularity of the iron pen 1 to the ball mill 4 is achieved only by the crank rocker mechanism, thereby enabling the plated film substrate to be subjected to uniform force during the grinding process.

[0057] The present embodiment provides a grinding process of the plated film substrate material grinding device. The grinding process changes the uncontrollable rotation of the clamp 3 and the plated film substrate on the upper side of the ball mill 4. The grinding process includes: the plated film substrate moves back and forth on the upper side of the rotating ball mill 4. When the plated film substrate is located on the upper side of the middle part of the ball mill 4, the plated film substrate adjusts the posture with the rotation of the ball mill 4. When the plated film substrate is located on the upper side of the outer part of the ball mill 4, the plated film substrate stops rotating and is ground by the ball mill 4.

[0058] The plated film substrate rotates with the rotation of the ball mill 4 on the upper side of the middle part of the ball mill 4. The rotation can adjust the posture angle of the plated film substrate. The linear speed of the middle part of the ball mill 4 is small, and the influence on the grinding efficiency is small. The plated film substrate no longer rotates on the upper side of the outer part of the ball mill 4, and is rapidly ground by the outer area with high linear speed. The high-efficiency grinding and the grinding quality of the plated film substrate are considered.

[0059] The relative rotation between the iron pen 1 and the clamp 3 is limited by the semispherical spline. In the embodiment, the iron pen 1 is two-segmented, and a clutch is arranged in the middle of the iron pen 1 to realize the rotation control of the clamp 3 and the coated substrate. Specifically, the clutch includes a fixed friction plate 5, a movable friction plate 6, and an elastic member 47 for moving the movable friction plate 6 to the fixed friction plate 5. The iron pen 1 is divided into two segments which are coaxially connected. The fixed friction plate 5 is connected with the upper end of the lower segment of the iron pen 1, and the movable friction plate 6 is axially slidably connected with the upper segment of the iron pen 1.

[0060] Since the friction plate is a consumable part, the friction plate can be replaced in the design of the embodiment, so that the iron pen 1 with the clutch can be used for a long time, and the use and maintenance cost is reduced. The lower side of the fixed friction plate 5 is provided with a first threaded cylinder 40 which is threadedly connected with the lower segment of the iron pen 1. The upper side of the fixed friction plate 5 is provided with a convex ring 41, the center of which is provided for the lower end of the upper segment of the iron pen 1 to extend into. The upper side of the convex ring 41 is connected with a rotating ring 42 through a bolt. The lower end of the outer side of the upper segment of the iron pen 1 is provided with an annular groove 43 for the rotating ring 42 to rotate. The rotating ring 42 and the annular groove 43 are rotationally matched, so that the upper segment and the lower segment of the iron pen 1 can be coaxially rotated relative to each other. The rotating ring 42 and the convex ring 41 are separated by disassembling the bolt, and then the fixed friction plate 5 is separated from the lower segment of the iron pen 1 through the threaded connection structure of the first threaded cylinder 40, so that the fixed friction plate 5 can be disassembled and replaced.

[0061] The movable friction plate 6 is an annular structure surrounding the iron pen 1, and the position is corresponding to the fixed friction plate 5. The outer side of the upper segment of the iron pen 1 is axially slidably connected with a sliding member 45. The outer side of the lower part of the upper segment of the iron pen 1 is symmetrically provided with vertical protrusions 48. The inner ring side of the sliding member 45 is provided with sliding grooves 49 which are slidably matched with the vertical protrusions 48, so that the sliding member 45 can only slide on the outer side of the iron pen 1, but cannot rotate.

[0062] The upper side of the movable friction plate 6 is provided with a second threaded cylinder 44 which is threadedly connected with the sliding member 45. The lower part of the sliding member 45 is provided with internal threads which can be threadedly disassembled with the second threaded cylinder 44 on the upper side of the movable friction plate 6, so that the movable friction plate 6 can be disassembled and replaced. The inner diameter of the second threaded cylinder 44 is larger than the outer diameter of the rotating ring 42 and the convex ring 41, which does not affect the contact and combination of the movable friction plate 6 and the fixed friction plate 5. The outer side of the upper side of the fixed friction plate 5 and the lower side of the movable friction plate 6 are provided with rough friction surfaces. The elastic member 47 provides pressure to limit the relative rotation between the fixed friction plate 5 and the movable friction plate 6.

[0063] The elastic member 47 is a coil spring, the upper section of the stylus 1 is provided with a fixing ring 46, the elastic member 47 is sleeved on the outer side of the stylus 1, the upper end is connected to the lower side of the fixing ring 46, and the lower end abuts against the upper side of the sliding member 45; the sliding member 45 is provided with a flexible rubber roller 7 on one side, the flexible rubber roller 7 is located on the upper side of the arc-shaped support 8, the arc-shaped support 8 is provided with a gantry 18 on the lower side, the gantry 18 is installed on the upper side of the machine box 13 and crosses the liquid container 15, the arc-shaped support 8 is in the form of an arc-shaped plate and is located on the upper side of the gantry 18, and the arc-shaped support 8 has an arc-shaped surface on the upper side.

[0064] The arc-shaped support 8 limits the dynamic friction plate 6 through the flexible rubber roller 7, the arc-shaped support 8 has an upward protrusion 24 in the middle, when the protrusion 24 corresponds to the dynamic friction plate 6, the protrusion 24 lifts the flexible rubber roller 7 and the sliding member 45, so that the dynamic friction plate 6 is separated from the fixed friction plate 5, and at this time, the coated substrate is located on the upper side of the middle of the ball mill 4, at this time, the lower section of the stylus 1 can be freely rotated, so that the coated substrate is rotated with the ball mill 4 to adjust the angle, the ball mill 4 has a constant rotating speed, the coated substrate is rotated by a certain angle each time, and uniform grinding is realized through regular periodic rotation adjustment and angle change; when the arc-shaped support 8 corresponds to the dynamic friction plate 6 at the positions other than the protrusion 24 (i.e. the positions on both sides of the middle protrusion 24), the dynamic friction plate 6 is lowered to contact and combine with the fixed friction plate 5 due to the absence of the limitation of the protrusion 24, the lower section of the stylus 1 cannot be rotated through the friction limiting action, and the coated substrate is ground by the ball mill 4.

[0065] The embodiment has a grinding pressure adjusting function, the driven gear 26 and the swing frame 25 in the crank rocker mechanism are rotationally connected to the rotating drum 9, the machine box 13 is provided with a fixed shaft 21 and a shaft stand 22 supporting the fixed shaft 21, and the rotating drum 9 is rotationally installed on the outer side of the fixed shaft 21, so that the whole crank rocker mechanism can be rotated, thereby providing conditions for grinding pressure adjustment.

[0066] The rotating drum 9 is connected with an inverted L-shaped plate 23 on one side, the inverted L-shaped plate 23 is connected with a tension spring 10, the tension spring 10 makes the rotating drum 9 and the whole crank rocker mechanism rotate, the tension spring 10 has a similar action to a bicycle foot spring, and in the embodiment, the tension spring 10 makes the mounting frame 2 have a first state of approaching the ball mill 4 and a second state of being away from the ball mill 4. The tension spring 10 can exert grinding pressure, the tension spring 10 makes the crank rocker mechanism, the mounting frame 2 and the stylus 1 overcome the elastic force of the elastic member 47 and approach the ball mill 4, thereby providing pressure of the coated substrate to the ball mill 4.

[0067] In order to realize the adjustment of the tension of the tension spring 10, the lower end of the tension spring 10 is connected with a pull plate 11, the pull plate 11 is provided with an adjusting bolt 12, the upper side of a machine box 13 is provided with a threaded hole 14, the adjusting bolt 12 is threadedly connected with the threaded hole 14, the height of the pull plate 11 can be changed by rotating the adjusting bolt 12, thereby the height of the lower end of the tension spring 10 is adjusted, the tension state of the tension spring 10 is adjusted, the force applied by the tension spring 10 to the rotating drum 9 and the crank rocker mechanism is changed, and thereby the grinding pressure is adjusted.

[0068] In the embodiment, the tension spring 10 makes the mounting rack 2 have a second state of moving away from the ball mill 4, the pen 1, the mounting rack 2 and the crank rocker mechanism can be turned over as a whole, the pen 1 is convenient to move away from the ball mill 4 to assemble and disassemble the clamp 3 and the coated substrate; the upper side of the machine box 13 is provided with a support 19, the support 19 limits the position of the swing rack 25 corresponding to the swing rack 25 when the mounting rack 2 is in the second state.
