Description

Technical Field

[0001] This invention relates to the field of glass processing technology, specifically to an automatic edge grinding device for tempered glass. Background Technology

[0002] Tempered glass is a type of prestressed glass. It is made by first cutting ordinary annealed glass into the required size, then heating it to a temperature close to its softening point, and then rapidly and evenly cooling it. The edges of the cut glass sheet are very sharp. If they are not treated, they will affect the safety of subsequent operations and the quality of the glass. Therefore, the edges of tempered glass need to be ground and polished after cutting to make them smooth and flat.

[0003] When grinding the edges of temporarily modified round tempered glass at the construction site, the common practice is to manually operate an angle grinder with different grits of grinding discs. However, this grinding method makes it difficult to control the amount of grinding on the tempered glass, and it is easy to over-grind, causing the round tempered glass to become out of round, thus reducing the grinding effect. In addition, when changing to different grits of grinding discs for fine grinding of round tempered glass, the current grinding disc needs to be removed first before replacing and installing other grinding discs. The overall replacement operation is relatively complicated, reducing the grinding efficiency. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is: an automatic tempered glass edge grinding device, including a disc plate and a fixed column coaxially fixed on its upper side, a centering mechanism is also provided on the disc plate, and an edge grinding mechanism is provided on the fixed column.

[0005] The centering mechanism includes extension plates evenly spaced along the circumference of the disc plate, and the extension plates are linearly slidable along the radial direction of the disc plate. The end of the extension plate away from the disc plate is connected to a backing plate through a connecting plate assembly. A moving assembly for moving the backing plate is provided on the extension plate. The backing plate synchronously abuts against the edge of the circular tempered glass, so that the disc plate and the circular tempered glass are concentric.

[0006] The grinding mechanism includes an adjusting component, a limiting component, and a clearance component. The adjusting component is rotatably mounted on the upper outer side of the fixed column and is a telescopic structure. A mounting frame is symmetrically arranged on the lower part of the telescopic section of the adjusting component near the disc plate, and the mounting frame slides radially along the fixed column. Grinding rollers, rotatably connected to the mounting frame, are symmetrically arranged vertically on the side of the mounting frame near the disc plate. Two grinding rollers on the same mounting frame are arranged perpendicularly to each other, and the grinding grit of the grinding rollers on different mounting frames is different. A replacement component for quickly changing the grinding rollers is also provided at the lower part of the telescopic section of the adjusting component.

[0007] The limiting component is used to control the grinding depth of the grinding roller to be consistent; the yielding component cooperates with the connecting plate component to control the movement of the abutment plate to avoid the grinding roller.

[0008] Preferably, the connecting plate assembly includes a first hinge plate and a second hinge plate hinged to the end of the extension plate away from the disc plate. The hinge point of the first hinge plate and the extension plate is located above the hinge point of the second hinge plate and the extension plate and close to the center of the disc plate. The end of the first hinge plate away from the extension plate is hinged to the upper part of the side of the abutment plate. The end of the second hinge plate away from the extension plate is hinged to the middle part of the side of the abutment plate. A torsion spring is provided at the hinge positions of the first hinge plate, the second hinge plate and the extension plate.

[0009] Preferably, the moving component includes a moving block that is slidably disposed on the upper side of the extension plate along the length direction of the extension plate, an active spring is provided between the moving block and the extension plate, a through groove is provided on the side of the extension plate away from the disc plate, and a pull rope is provided between the lower part of the moving block and the side of the abutment plate facing the center of the disc plate.

[0010] Preferably, the adjusting component includes a rotating square rod rotatably connected to the fixed column. A rectangular groove is provided in the middle of the rotating square rod. An L-shaped plate is slidably arranged in the rectangular groove along the length direction of the rotating square rod. A sliding plate is slidably arranged on the vertical section of the L-shaped plate away from the side of the corresponding rectangular groove. The mounting bracket is slidably connected to the sliding plate through a guide post on it.

[0011] Preferably, the clearance component includes a position block that is slidably disposed on its lower side along the length direction of the rotating square rod, an arc-shaped square rod with its inner arc surface facing away from the disc plate is fixedly installed on the lower part of the position block away from the disc plate, and a protruding column is fixedly installed on the upper part of the moving block.

[0012] Preferably, the lower part of the rotating square rod is rotatably provided with an adjusting screw, which is threadedly connected to the position block. An inclined square rod for pushing the protruding column away from the disc plate is fixedly installed on the lower part of the position block near the disc plate.

[0013] Preferably, the limiting component includes a roller frame that is slidably disposed on the inner side of the middle part of the sliding plate along the radial direction of the disc plate. An abutment roller is rotatably disposed on the roller frame, and a first screw that is threadedly connected to the sliding plate is rotatably disposed on the roller frame. A T-shaped block is slidably disposed on the upper part of the rotating square rod along its length direction. A second screw is threadedly connected to the vertical section of the T-shaped block. A tension spring telescopic rod is connected between the second screw and the vertical section of the L-shaped plate. The T-shaped block is locked to the rotating square rod by fastening screws.

[0014] Preferably, the replacement component includes a guide post fixedly installed on the same mounting bracket, a vertical plate at the end away from the disc plate, a linkage plate rotatably arranged on the outer side of the sliding plate, slots symmetrically opened on the linkage plate, the vertical plate engaging with the slots of the linkage plate via a vertical post rotatably installed at its lower part, and an L-shaped locking block slidably arranged on the upper part of the outer side of the sliding plate, with a helical spring between the locking block and the side end of the sliding plate.

[0015] Preferably, the sliding plate is provided with two sets of symmetrically arranged sliding blocks, each set consisting of two sliding blocks arranged symmetrically up and down. The sliding blocks are slidably connected to the sliding plate. A bidirectional screw is symmetrically rotatably provided on the sliding plate. The bidirectional screw is threadedly connected to a set of sliding blocks at the corresponding position. A rotating roller is rotatably provided on the side of the sliding block near the disc plate.

[0016] Preferably, an ear plate is rotatably provided on the upper side of the disc plate, and a push-pull plate corresponding to the extension plate is hinged to the side of the ear plate away from the disc plate. The end of the push-pull plate away from the ear plate is hinged to the extension plate at the corresponding position. The extension plate is slidably mounted on the upper part of the support plate. The support plate is fixedly mounted on the annular surface of the disc plate. The extension plate is locked in position with the support plate by locking screws. An electric suction cup is fixedly installed at the bottom of the disc plate.

[0017] The beneficial effects of the present invention are as follows: First, the present invention uses a synchronously moving extension plate to abut against the edge of the circular tempered glass through abutment plate, so that the disc plate can be positioned at the center of the circular tempered glass. Then, by rotating the rotating square rod, the grinding roller is driven to rotate around the edge of the circular tempered glass, thereby enabling the grinding roller to quickly grind the edge of the circular tempered glass and improve grinding efficiency.

[0018] Second, the present invention uses a limiting component to control the grinding depth of the grinding roller, so that the grinding amount of the grinding roller on the round tempered glass is kept uniform and consistent, thereby preventing the round tempered glass from becoming out of round due to excessive grinding, thus ensuring the grinding effect. Moreover, when grinding the edge of round tempered glass of different diameters, the limiting component can also pull the grinding roller to move with the same force, preventing the grinding feed of the grinding roller from being too large, which would cause the round tempered glass to break.

[0019] Third, this invention uses a clearance component in conjunction with a connecting plate component to move the abutment plate, so that when the grinding roller moves to the position of the abutment plate, the abutment plate can automatically move to the upper side of the extension plate, thereby preventing the abutment plate from obstructing the movement of the grinding roller. At the same time, the position of the disc plate can still be fixed by the other abutment plates, and the disc plate can be tightly attached to the center position of the circular tempered glass by the electric suction cup on it, preventing the position of the disc plate from changing, thereby ensuring that the grinding roller grinds the edge of the circular tempered glass consistently.

[0020] Fourth, the present invention uses interchangeable components to quickly change the grinding rollers of different grit sizes to contact the edge of the round tempered glass, thereby achieving rapid grinding of the round tempered glass with different grit sizes and further improving the grinding efficiency.

Detailed Implementation

[0032] The embodiments of the present invention are described in detail below. The embodiments described below are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention. Where specific techniques or conditions are not specified in the embodiments, they shall be performed in accordance with the techniques or conditions described in the literature in the art or in accordance with the product manual.

[0033] See Figure 1 and Figure 2 An automatic edge grinding device for tempered glass includes a disc plate 1, a coaxial fixing column 2 fixedly installed on the upper side of the disc plate 1, a centering mechanism 3 for positioning to the center of the circular tempered glass on the disc plate 1, and an edge grinding mechanism 4 on the fixing column 2.

[0034] When it is necessary to grind the edge of a round tempered glass, first place the disc plate 1 on the upper side of the round tempered glass, then fix the disc plate 1 at the same center position as the round tempered glass through the centering mechanism 3, and then grind the edge of the round tempered glass circumferentially through the grinding mechanism 4.

[0035] See Figure 1 , Figure 2 and Figure 3 The centering mechanism 3 includes a support plate 31 that is fixedly installed at equal intervals along the circumference of the disc plate 1 on its annular surface. The support plate 31 extends radially along the disc plate 1. An extension plate 32 is slidably provided on the upper part of the support plate 31 along its length direction. The end of the extension plate 32 away from the disc plate 1 is connected by a connecting plate assembly 33 to an abutment plate 34 for pressing against the edge of the circular tempered glass.

[0036] See Figure 1 , Figure 2 , Figure 3 and Figure 4 The centering mechanism 3 also includes a moving component 35 disposed on the extension plate 32. The moving component 35 includes a moving block 351 that is slidably disposed on the upper side of the extension plate 32 along the length direction of the extension plate 32. An active spring is disposed between the moving block 351 and the extension plate 32. A through groove is provided on the side of the extension plate 32 away from the disc plate 1. A pull rope 352 is disposed between the lower part of the moving block 351 and the side of the abutment plate 34 facing the center of the disc plate 1.

[0037] In the initial state, the abutment plate 34 is located on the side of the extension plate 32 away from the disc plate 1, and the abutment plate 34 is in a vertical state. The moving block 351 is located on the upper side of the extension plate 32 away from the disc plate 1 under the push of the active spring force, and the moving block 351 blocks the upper part of the abutment plate 34 to prevent the abutment plate 34 from rotating.

[0038] See Figure 1 , Figure 2 , Figure 3 and Figure 4 A lug plate 36 is rotatably mounted on the upper side of the disc plate 1. A push-pull plate 361 corresponding to the extension plate 32 is hinged to the side of the lug plate 36 away from the disc plate 1. The end of the push-pull plate 361 away from the lug plate 36 is hinged to the extension plate 32 at the corresponding position. The extension plate 32 is locked to the support plate 31 by locking screws. An electric suction cup 362 is fixedly installed at the bottom of the disc plate 1.

[0039] When the disc plate 1 is placed on the upper side of the circular tempered glass, the abutment plate 34 is located on the outer side of the circular tempered glass. Then, the operator pulls one of the extension plates 32 to move closer to the disc plate 1, so that the extension plate 32 drives the inner side of the abutment plate 34 to abut against the circular tempered glass. The extension plate 32 drives the ear plate 36 to rotate through the corresponding push-pull plate 361. The ear plate 36, in turn, drives the corresponding extension plates 32 to move synchronously through the other push-pull plates 361, thereby making all the extension plates 32 move synchronously along the radial direction of the disc plate 1.

[0040] When all the extension plates 32 bring their abutment plates 34 against the circular tempered glass, the circular tempered glass pushes the extension plates 32 with the reaction force of the abutment plates 34. The extension plates 32 push the ear plate 36 through the push-pull plate 361, so that the ear plate 36 moves the disc plate 1 to the center of the circular tempered glass. The disc plate 1 moves the electric suction cup 362 to the center of the circular tempered glass. Then the operator starts the electric suction cup 362 to adhere to the circular tempered glass, so that the disc plate 1 is fixed at the center of the circular tempered glass.

[0041] The operator then locks the extension plate 32 and the support plate 31 into a whole by turning the locking screw, so that the extension plate 32 drives the abutment plate 34 to always abut against the outer side of the circular tempered glass, thereby further consolidating the position of the disc plate 1.

[0042] See Figure 1 , Figure 6 , Figure 7 and Figure 8 The edge grinding mechanism 4 includes an adjusting component that is a telescopic structure. The adjusting component includes a rotating square rod 41 rotatably mounted on the upper outer side of the fixed column 2. A rectangular groove 42 is provided in the middle of the rotating square rod 41. An L-shaped plate 43 is slidably mounted in the rectangular groove 42 along the length direction of the rotating square rod 41. A sliding plate 44 is slidably mounted on the vertical section of the L-shaped plate 43 away from the corresponding rectangular groove 42. The rotating square rod 41 serves as the fixed section of the telescopic structure, while the L-shaped plate 43 and the sliding plate 44 together serve as the telescopic section of the telescopic structure. A mounting frame 45 is symmetrically mounted on the lower part of the sliding plate 44 near the disc plate 1. The mounting frame 45 is slidably connected to the sliding plate 44 along the thickness direction through a guide post 46 on it. That is, the mounting frame 45 slides radially along the fixed column 2. Grinding rollers 47 are symmetrically mounted on the side of the mounting frame 45 near the disc plate 1 and are rotatably connected to it. The two grinding rollers 47 on the same mounting frame 45 are arranged perpendicular to each other, and the grinding grit of the grinding rollers 47 on different mounting frames 45 is different.

[0043] After the position of the disc plate 1 is fixed, the operator manually moves the extended L-shaped plate 43, causing the L-shaped plate 43 to move the sliding plate 44 to the outside of the circular tempered glass. Then the operator moves the sliding plate 44 downward, causing the sliding plate 44 to move the grinding roller 47 downward through the mounting bracket 45 to correspond with the circular tempered glass ring. After that, the operator moves the L-shaped plate 43 closer to the disc plate 1, causing the L-shaped plate 43 to move the grinding roller 47 against the edge of the circular tempered glass through the sliding plate 44.

[0044] See Figure 1 , Figure 6 , Figure 7 and Figure 8 The grinding mechanism 4 also includes a replacement component 49 disposed on the sliding plate 44. The replacement component 49 is used for quick replacement of the grinding roller 47. The replacement component 49 includes a guide post 46 fixedly installed on the same mounting bracket 45 and a vertical plate 491 at the end away from the disc plate 1. A linkage plate 492 is rotatably disposed on the outer side of the sliding plate 44. The linkage plate 492 has symmetrical slots. The vertical plate 491 cooperates with the slots of the linkage plate 492 through the vertical post rotatably installed at its lower part. An L-shaped locking block 493 is slidably disposed on the upper part of the outer side of the sliding plate 44. A helical spring is disposed between the locking block 493 and the side end of the sliding plate 44.

[0045] In the initial state, the mounting bracket 45 with the smaller grinding roller 47 is located close to the disc plate 1, while the mounting bracket 45 with the larger grinding roller 47 is located away from the disc plate 1. This ensures that when the smaller grinding roller 47 contacts the circular tempered glass, the larger grinding roller 47 does not contact the circular tempered glass. At the same time, the mounting bracket 45 with the smaller grinding roller 47, through the guide post 46, drives the vertical plate 491 at the corresponding position to abut against the side of the sliding plate 44. The helical spring pushes the locking block 493 downward through its own elastic force, so that the vertical section of the locking block 493 abuts against the side of the vertical plate 491 that abuts against the side of the sliding plate 44. This fixes the vertical plate 491 between the sliding plate 44 and the vertical section of the locking block 493, preventing the corresponding grinding roller 47 from moving radially along the disc plate 1 relative to the sliding plate 44 during grinding.

[0046] See Figure 1 , Figure 6 and Figure 7 Two sets of symmetrically arranged sliding blocks 441 are provided on the sliding plate 44. Each set consists of two sliding blocks 441 arranged vertically and vertically. The sliding blocks 441 are slidably connected to the sliding plate 44. A bidirectional screw 442 is symmetrically rotatably provided on the sliding plate 44. The bidirectional screw 442 is threadedly connected to a set of sliding blocks 441 at the corresponding position. A rotating roller 443 is rotatably provided on the side of the sliding block 441 near the disc plate 1.

[0047] When the polishing roller 47 moves to abut against the circular tempered glass, the sliding plate 44 synchronously drives the rotating roller 443 to move to the corresponding position on the circular tempered glass through the sliding block 441. This ensures that the rotating rollers 443 on the two sliding blocks 441 in the same group are located on the upper and lower sides of the circular tempered glass, respectively. Then, the operator manually rotates the bidirectional screw 442, causing the bidirectional screw 442 to drive the rotating rollers 443 on it to move closer to each other through the two sliding blocks 441 in the same group. This causes the rotating rollers 443 to be clamped onto the circular tempered glass. Consequently, the circular tempered glass adjusts the height of the sliding plate 44 through the reaction force on the rotating rollers 443, ensuring that the polishing rollers 47 on both the upper and lower sides of the circular tempered glass can simultaneously contact the circular tempered glass, thus ensuring that the polishing effect of the rotating rollers 443 on the upper and lower edges of the circular tempered glass is consistent.

[0048] See Figure 1 , Figure 4 , Figure 6 , Figure 7 and Figure 8The edge grinding mechanism 4 also includes a limiting component 48 for controlling the grinding depth of the grinding roller 47 to be consistent. The limiting component 48 includes a roller frame 481 that is slidably disposed on the inner side of the middle part of the sliding plate 44 along the radial direction of the disc plate 1. An abutment roller 482 is rotatably disposed on the roller frame 481. A first screw 483 that is threadedly connected to the sliding plate 44 is rotatably disposed on the roller frame 481. A T-shaped block 484 is slidably disposed on the upper part of the rotating square rod 41 along its length direction. A second screw 485 is threadedly connected to the vertical section of the T-shaped block 484. A tension spring telescopic rod 486 is connected between the second screw 485 and the vertical section of the L-shaped plate 43. The T-shaped block 484 is locked to the rotating square rod 41 by fastening screws.

[0049] In the initial state, the tension spring telescopic rod 486 is at its shortest length, and the fixed section of the tension spring telescopic rod 486 is located away from the T-block 484. While moving the L-shaped plate 43, the T-shaped block 484 is also moved. When the rotating rollers 443 with smaller grinding grits on both the upper and lower sides are against the circular tempered glass, the operator locks the T-shaped block 484 and the rotating square rod 41 into a whole by turning the fastening screw. Then, the operator manually turns the second screw 485 to the end of its thread. During this process, the second screw 485 drives the tension spring telescopic rod 486 to move synchronously. Since the grinding roller 47 is against the annular surface of the circular tempered glass, the distance between the sliding plate 44 and the rotation point of the rotating square rod 41 remains unchanged, so that the position of the L-shaped plate 43 does not move. Therefore, the movement of the second screw 485 will cause the telescopic section of the tension spring telescopic rod 486 to extend. When grinding the edge of circular tempered glass of different diameters, the tension spring telescopic rod 486 always starts to extend from the shortest total length state to ensure that the telescopic section of the tension spring telescopic rod 486 is pulled out by the same distance, so that the tension of the tension spring telescopic rod 486 on the grinding roller 47 is the same.

[0050] Then, the operator manually rotates the No. 1 screw 483 according to the degree of polishing, so that the No. 1 screw 483 drives the abutment roller 482 to adjust its position through the roller frame 481. The distance between the abutment roller 482 and the edge of the circular tempered glass is equal to the depth of polishing of the edge of the circular tempered glass by the polishing roller 47.

[0051] See Figure 6 , Figure 7 and Figure 8 An actuator motor 451 is fixedly mounted on the mounting bracket 45. The output shaft of the actuator motor 451 is fixedly connected to the upper grinding roller 47. Bevel gears 471 are fixedly mounted on the ends of the grinding rollers 47 on the same mounting bracket 45 that are close to each other, and the two bevel gears 471 at corresponding positions mesh.

[0052] The start-up motor 451 drives the corresponding grinding roller 47 to rotate. The grinding roller 47 drives another grinding roller 47 on the same mounting bracket 45 to rotate synchronously through the bevel gear 471, so that the grinding roller 47 in contact with the circular tempered glass begins to grind the edge of the circular tempered glass. At the same time, the operator manually rotates the rotating square rod 41, so that the rotating square rod 41 drives the grinding roller 47 to rotate around the edge of the circular tempered glass, so that the grinding roller 47 begins to grind the edge of the circular tempered glass. During grinding, the tension spring telescopic rod 486 pulls the sliding plate 44 towards the disc plate 1 through its own tension, so that the sliding plate 44 drives the grinding roller 47 to always be in contact with the edge of the circular tempered glass.

[0053] See Figure 1 , Figure 3 , Figure 4 , Figure 6 and Figure 9 The grinding mechanism 4 also includes a clearance component 40, which cooperates with the connecting plate assembly 33 to control the movement of the abutment plate 34 to avoid the grinding roller 47. The clearance component 40 includes a position block 401 that is slidably disposed on its lower side along the length direction of the rotating square rod 41. An arc-shaped square rod 402 with its inner arc surface facing away from the disc plate 1 is fixedly installed on the lower part of the position block 401 away from the disc plate 1. A protruding column 403 is fixedly installed on the upper part of the moving block 351.

[0054] See Figure 1 , Figure 6 and Figure 9 The lower part of the rotating square rod 41 is provided with an adjusting screw 404, which is threadedly connected to the position block 401. The lower part of the position block 401 is fixedly installed with an inclined square rod 405 for pushing the protruding column 403 away from the disc plate 1.

[0055] See Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The connecting plate assembly 33 includes a first hinge plate 331 and a second hinge plate 332 hinged to the end of the extension plate 32 away from the disc plate 1. The hinge point of the first hinge plate 331 and the extension plate 32 is located above the hinge point of the second hinge plate 332 and the extension plate 32 and close to the center of the disc plate 1. The end of the first hinge plate 331 away from the extension plate 32 is hinged to the upper side of the abutment plate 34. The end of the second hinge plate 332 away from the extension plate 32 is hinged to the middle side of the abutment plate 34. A torsion spring is provided at the hinge position of the first hinge plate 331, the second hinge plate 332 and the extension plate 32. The torsion spring is not shown in the figure. To improve the stability of the abutment plate 34 during rotation, the connecting plate assemblies 33 are symmetrically arranged on both sides of the abutment plate 34. The ends of the first hinge plate 331 and the second hinge plate 332 in the same connecting plate assembly 33, away from the extension plate 32, are hinged to the same side of the abutment plate 34 (e.g., ...). Figure 2 and Figure 3 (As shown).

[0056] See Figures 1-9 The operator manually rotates the adjusting screw 404 according to the position of the moving block 351 in advance, so that the adjusting screw 404 adjusts the arc-shaped square rod 402 and the inclined square rod 405 to the appropriate position through the position block 401. When the square rod 41 rotates, the rotating square rod 41 drives the arc-shaped square rod 402 and the inclined square rod 405 to move synchronously through the position block 401. As the grinding roller 47 gradually approaches the corresponding position of the abutment plate 34, the outer arc surface of the end of the arc-shaped square rod 402 away from the position block 401 first contacts the corresponding position of the protruding column 403, so that the arc-shaped square rod 402 pushes the protruding column 403 towards the direction of the disc plate 1. The protruding column 403 drives the moving block 351 at the corresponding position to move synchronously and compress the active spring.

[0057] When the moving block 351 moves to a position where it no longer obstructs the upper side of the abutment plate 34, the moving block 351 tightens the pull rope 352. The moving block 351 then continues to move, pulling the abutment plate 34 via the pull rope 352. This causes the abutment plate 34 to rotate to a horizontal position via the first hinge plate 331 and the second hinge plate 332, simultaneously causing the abutment plate 34 to adhere to the upper part of the extension plate 32, thus preventing the abutment plate 34 from obstructing the grinding roller 47. When the abutment plate 34 rotates from a vertical to a horizontal position via the first hinge plate 331 and the second hinge plate 332, the lower end of the abutment plate 34 can first rotate away from the disc plate 1, preventing the abutment plate 34 from rubbing against the edge of the circular tempered glass.

[0058] When the grinding roller 47 moves past the abutment plate 34, the arc-shaped square rod 402 no longer pushes the protruding column 403. The active spring pushes the moving block 351 back to its original position through its own rebound force. The tension of the moving block 351 on the abutment plate 34 through the pull rope 352 gradually decreases. At the same time, the torsion spring drives the first hinge plate 331 and the second hinge plate 332 to rotate through its own rebound force, so that the first hinge plate 331 and the second hinge plate 332 drive the abutment plate 34 to rotate and return to its original position. In order to prevent the spring force from being insufficient to drive the abutment plate 34 to rotate to the state of abutting against the circular tempered glass (i.e., the vertical state), the side of the inclined square rod 405 close to the outer arc surface of the arc-shaped square rod 402 can contact the protruding column 403 to push the protruding column 403 away from the disc plate 1, so that the moving block 351 returns to its initial position, thereby causing the moving block 351 to push the abutment plate 34 to rotate to the vertical state.

[0059] It should be noted that the upper side of the extension plate 32 away from the disc plate 1 is rounded, and the lower side of the moving block 351 away from the disc plate 1 is provided with an inclined surface. The inclined surface on the moving block 351 can smoothly push the abutment plate 34 to move, so that the moving block 351 can move to the upper side of the abutment plate 34, thereby fixing and limiting the upper and lower position of the abutment plate 34.

[0060] When the sliding plate 44 drives the abutment roller 482 to abut against the edge of the circular tempered glass, the tension spring extension rod 486 can no longer move the grinding roller 47 by pulling the sliding plate 44, so that the grinding roller 47 with a smaller grinding grit completes the rough grinding of the edge of the circular tempered glass. Then the operator manually moves the locking block 493 upward, and then the operator manually pushes the vertical plate 491 connected to the grinding roller 47 with a larger grinding grit towards the direction of the disc plate 1, so that the vertical plate 491 connected to the grinding roller 47 with a larger grinding grit abuts against the sliding plate 44. Then the locking block 493 moves downward to fix the position of the vertical plate 491 connected to the grinding roller 47 with a larger grinding grit.

[0061] When the vertical plate 491 connected to the grinding roller 47 with a larger grinding grit moves, it drives the linkage plate 492 to rotate, so that the linkage plate 492 drives the vertical plate 491 of the corresponding grinding roller 47 with a smaller grinding grit to move away from the disc plate 1. Then, the actuator motor 451 connected to the grinding roller 47 with a larger grinding grit is started, and the rotating square rod 41 is rotated, so that the grinding roller 47 with a larger grinding grit begins to finely grind the edge of the circular tempered glass.

[0062] It should be noted that the diameter of the grinding roller 47 with a smaller grinding grit is smaller than that of the grinding roller 47 with a larger grinding grit. This means that when the grinding roller 47 with a larger grinding grit comes into contact with the edge of the circular tempered glass, the reaction force of the circular tempered glass on the grinding roller 47 with a larger grinding grit can push the sliding plate 44 to move away from the disc plate 1. The sliding plate 44 then causes the abutment roller 482 to no longer abut against the circular tempered glass.

[0063] See Figures 1-9 The present invention further includes the following steps when polishing circular tempered glass: First, the disc plate 1 is placed on the upper side of the circular tempered glass. The operator pulls the extension plate 32 to drive the abutment plate 34 to abut against the circular tempered glass, so that the disc plate 1 moves to the center position of the circular tempered glass. The operator then activates the electric suction cup 362 to adhere to the circular tempered glass. Afterwards, the operator locks the extension plate 32 and the support plate 31 into a whole by rotating the locking screw.

[0064] It should be noted that the round tempered glass can be fixed to the upper part of the existing workbench by manual pressing or by electric suction cups and other equipment. The overall size of the workbench is smaller than the size of the round tempered glass. After the disc plate 1 is moved to the center of the round tempered glass and the electric suction cup 362 is attached to the round tempered glass, the disc plate 1 can be manually pressed to press the round tempered glass. Alternatively, before the disc plate 1 is placed on the upper side of the round tempered glass, the lower middle part of the round tempered glass can be attached by electric suction cups and other equipment. The electric suction cups and other equipment are set on the workbench.

[0065] The second step involves the operator manually moving the polishing roller 47 against the edge of the round tempered glass, so that the rotating rollers 443 on the two sliding blocks 441 in the same group are positioned on the upper and lower sides of the round tempered glass. The operator then manually rotates the bidirectional screw 442, causing the rotating rollers 443 to clamp onto the round tempered glass, thereby allowing the polishing rollers 47 on both the upper and lower sides to contact the round tempered glass simultaneously.

[0066] Third, the operator locks the T-block 484 and the rotating square rod 41 into a whole by turning the fastening screw. Then the operator manually turns the second screw 485 to the end of its thread, so that the second screw 485 drives the extension section of the tension spring telescopic rod 486 to extend, and the tension spring telescopic rod 486 applies tension to the grinding roller 47.

[0067] The fourth step involves the operator manually rotating screw 483 according to the degree of polishing. Screw 483 then drives roller 482 to adjust its position via roller frame 481. The distance between roller 482 and the edge of the round tempered glass is equal to the depth to which the polishing roller 47 polishes the edge of the round tempered glass.

[0068] Fifth step, start the execution motor 451 to drive the corresponding grinding roller 47 to rotate. At the same time, the operator manually rotates the rotating square rod 41 to drive the grinding roller 47 to rotate around the edge of the circular tempered glass. The tension spring telescopic rod 486 pulls the grinding roller 47 towards the disc plate 1.

[0069] In the sixth step, when the grinding roller 47 rotates to the position of the abutment plate 34, the arc-shaped square rod 402 pushes the protruding column 403 to drive the abutment plate 34 to rotate to fit against the upper part of the extension plate 32, thereby avoiding the abutment plate 34 from blocking the grinding roller 47.

[0070] In the seventh step, when the abutting roller 482 abuts against the edge of the circular tempered glass, the operator manually moves the locking block 493 upward. Then, the operator manually pushes the vertical plate 491 connected to the grinding roller 47 with a larger mesh size towards the direction of the disc plate 1, so that the grinding roller 47 with a larger mesh size contacts the circular tempered glass. Then, the actuator motor 451 connected to the grinding roller 47 with a larger mesh size is started, and the rotating square rod 41 is rotated, so that the grinding roller 47 with a larger mesh size begins to finely grind the edge of the circular tempered glass.

[0071] Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions and variations to the above embodiments within the scope of the present invention, which are still covered within the protection scope of the present invention.
