Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and more specifically to a large-size glass peripheral polishing machine. Background Technology

[0002] Glass is an amorphous inorganic non-metallic material, generally made from a variety of inorganic minerals (such as quartz sand, borax, boric acid, barite, barium carbonate, limestone, feldspar, soda ash, etc.) as the main raw materials, with the addition of a small amount of auxiliary raw materials.

[0003] A search revealed a patent document with authorization announcement number CN214445476U, which discloses a horizontal vehicle-mounted glass polishing machine. The polishing machine includes a base with a flow channel. An X-axis ball screw drive mechanism is mounted on the flow channel. An X-axis slide is mounted on the X-axis slider of the X-axis ball screw drive mechanism. A servo motor assembly and a guide rail along the Y-axis are mounted on the X-axis slide. A Y-axis slider and a Y-axis slide are mounted on the guide rail. An eccentric wheel is located at the bottom of the Y-axis slide. The output shaft of the servo motor assembly is connected to the eccentric wheel, driving the Y-axis slide to move back and forth along the Y-axis. Two independently controlled Z-axis ball screw drive mechanisms are arranged side-by-side on one side of the Y-axis slide. Polishing wheel mechanisms are mounted on the Z-axis sliders of both Z-axis ball screw drive mechanisms.

[0004] In operation, the aforementioned polishing machine uses a fixture mounted on the Y-axis slide. The automotive glass to be polished is placed on the fixture and fixed by vacuum adsorption. During processing, the X-axis slide reciprocates left and right, while the Y-axis slide oscillates back and forth via an eccentric wheel. Two brush wheels are driven by a Z-axis ball screw drive mechanism. A pre-programmed sequence ensures the two brush wheels adhere closely to the glass, polishing it according to its curvature. However, this polishing machine can only polish the surface of the glass, not its edges. Even if the fixture's position is changed to allow for proper contact between the glass edges and the brush wheels, the machine's layout and structure result in significant polishing marks remaining at the glass edges after polishing, affecting subsequent processing.

[0005] To address this issue, we propose a large-size glass perimeter polishing machine to solve the problem of polishing marks appearing at the glass edges during the polishing process. Summary of the Invention

[0006] The purpose of this invention is to solve the problems in the prior art by proposing a large-size glass peripheral polishing machine. The polishing wheel in the polishing machine can reciprocate along its rotation axis while rotating, so that the polishing wheel can perform a smooth curve polishing treatment on the edge of the glass in a walking manner. This solves the problem of heavy polishing marks left on the edge of the glass in the previous processing. Furthermore, by setting the angle of the polishing wheel on the machine tool to be adjustable, the polishing wheel can perform walking polishing work in different directions, with a wide polishing range.

[0007] To address the above problems, the present invention provides the following technical solution: A large-size glass peripheral polishing machine includes a machine tool, a clamp for holding the glass surface, and a polishing assembly for polishing the glass edge. The polishing assembly includes a base, a movable seat, and a polishing wheel. The base is mounted on the machine tool, and the movable seat is slidably mounted on the side of the base facing the clamp. The polishing wheel is rotatably mounted on the movable seat. The polishing assembly also includes a drive component fixedly mounted on the base, which drives the movable seat to reciprocate along the rotation axis of the polishing wheel on the base.

[0008] As a further aspect of the present invention: the fixture includes a bearing plate rotatably mounted on the machine tool and a connecting plate slidably mounted on the machine tool along the vertical direction, wherein the connecting plate is located above the bearing plate and is driven to move by a top pressure member, and side pressure plates are hinged to both sides of the connecting plate so that when the side pressure plates move vertically downward with the connecting plate until they abut against the glass on the bearing plate, the top pressure member applies a vertically downward pressing force to the connecting plate and the side pressure plates.

[0009] As a further aspect of the present invention: the clamp further includes an adjusting member disposed on the connecting plate, the adjusting member being used to apply a vertically upward lifting force or a vertically downward dragging force to the side pressure plate to adapt to the reciprocating motion of the polishing wheel; when the moving seat drives the polishing wheel to apply a vertically downward cutting force to the edge of the glass, the adjusting member is used to apply a vertically upward lifting force to the side pressure plate; when the moving seat drives the polishing wheel to apply a vertically upward cutting force to the edge of the glass, the adjusting member is used to apply a vertically downward dragging force to the side pressure plate.

[0010] As a further aspect of the present invention: the clamp further includes a side cylinder disposed on the outer side of the side pressure plate and a flipping block hinged to the bottom side of the side pressure plate. The flipping block is hinged to the piston rod of the side cylinder and is located between the polishing wheel and the side pressure plate. The side cylinder is used to drive the flipping block to press against or move away from the glass to adapt to the reciprocating motion of the polishing wheel. When the moving seat drives the polishing wheel to apply a vertically downward cutting force to the edge of the glass, the side cylinder drives the flipping block away from the glass. When the moving seat drives the polishing wheel to apply a vertically upward cutting force to the edge of the glass, the side cylinder drives the flipping block to press against the glass.

[0011] As a further aspect of the present invention: the adjusting component includes a controller, two sets of crank connecting rods disposed opposite to each other on the connecting plate, and two sets of power sources disposed on the connecting plate. The two sets of power sources are located between the two sets of crank connecting rods. The disjoint ends of the two sets of crank connecting rods are respectively hinged to the inner sides of the two pressure plates, and the proximal ends of the two sets of crank connecting rods are respectively hinged to the execution ends of the two sets of power sources. The driving component and the two sets of power sources are all electrically connected to the controller, and the two sets of power sources are both controlled by the controller.

[0012] As a further embodiment of the present invention: the crank connecting rod includes a main arm rotatably disposed on the connecting plate, and a first auxiliary arm and a second auxiliary arm are respectively hinged at both ends of the main arm, and the first auxiliary arm is hinged to the inner side of the side pressure plate, and the second auxiliary arm is hinged to the execution end of the power source.

[0013] As a further aspect of the present invention: the lever arm from the first auxiliary arm to the fulcrum of the main arm is smaller than the lever arm from the second auxiliary arm to the fulcrum of the main arm, so that the force applied by the power source to the second auxiliary arm is amplified and transmitted to the first auxiliary arm.

[0014] As a further aspect of the present invention: the driving component includes a first motor fixedly mounted on the base, and the output shaft of the first motor is fixedly mounted with a reciprocating lead screw arranged in the vertical direction, and a connecting block is threaded onto the reciprocating lead screw, and the connecting block is fixedly connected to the movable seat.

[0015] As a further embodiment of the present invention: a second motor and an assembly cylinder are fixedly installed at the top and bottom of the movable seat, respectively, and the piston rod of the assembly cylinder is coaxially arranged with the output shaft of the second motor. The top end of the polishing wheel is fixedly connected to the output shaft of the second motor, and the bottom end of the polishing wheel is rotatably connected to the piston rod of the assembly cylinder.

[0016] As a further aspect of the present invention: a third motor is provided on the machine tool, a support plate is fixedly mounted on the output shaft of the third motor, the top pressure component is a top pressure cylinder mounted on the machine tool and located above the support plate, and the connecting plate is rotatably mounted on the piston rod of the top pressure cylinder.

[0017] As a further embodiment of the present invention: a guide rail is fixedly provided on the machine tool, and a base is slidably installed on the guide rail; a fourth motor is provided on the machine tool, and a threaded rod is fixedly provided on the output shaft of the fourth motor; the base is threadedly sleeved on the threaded rod.

[0018] As a further aspect of the present invention, the polishing assembly further includes two sets of nozzle assemblies disposed on the movable seat, and the two sets of nozzle assemblies are respectively located on both sides of the polishing wheel.

[0019] As a further aspect of the invention, the polishing assembly also includes a protective cover disposed on the movable base for covering the second motor.

[0020] As a further aspect of the invention, the polishing assembly also includes a fixed bracket disposed on the machine tool for mounting the top pressure cylinder.

[0021] Furthermore, this invention also proposes a control method for the aforementioned large-size glass peripheral polishing machine, which includes the following steps: Step 1: Place the glass on the support plate and use the top pressure component to drive the connecting plate and side pressure plate to move vertically downward until the top of the glass is pressed down. At this time, the side pressure plate will apply a vertical downward pressing force to the glass. The magnitude of this pressing force can be preset according to the glass type. Step 2: Use the second motor to drive the polishing wheel to rotate, and at the same time, use the drive component to drive the polishing wheel to reciprocate along its axis. Step 3: Use the fourth motor to drive the base to move until the polishing wheel on the base contacts the edge of the glass; Step 4: Based on the direction of the cutting force applied by the polishing wheel to the glass edge, the input command corresponding to the rotation direction of the first motor output shaft is transmitted to the controller. After processing, the controller acts on the power source, causing the power source to apply force to the side pressure plate via the crank-connecting rod. If the cutting force applied by the polishing wheel to the glass edge is vertically downward, the power source applies a vertically upward lifting force to the side pressure plate via the crank-connecting rod. This vertically upward lifting force is the same magnitude as the vertically downward cutting force, ensuring that the vertically downward force on the glass is always at the preset magnitude. If the cutting force applied by the polishing wheel to the glass edge is vertically upward, the power source applies a vertically downward dragging force to the side pressure plate via the crank-connecting rod. This vertically downward dragging force is the same magnitude as the vertically upward cutting force, ensuring that the vertically downward force on the glass is always at the preset magnitude.

[0022] Compared with the prior art, the present invention has the following beneficial effects: 1. With the base, moving seat and polishing wheel set up, the polishing wheel can rotate on the moving seat, and the moving seat can drive the polishing wheel to slide back and forth on the base. That is, the movement trajectory of the polishing wheel is a combination of its own rotation and reciprocating motion in the vertical direction. This movement mode of the polishing wheel can perform vertical up and down reciprocating polishing on the edge of the glass. The polishing effect is good and uniform. It effectively solves the problem of heavy polishing marks left on the edge of the glass in the early processing, and improves the aesthetics of the glass after processing. 2. With the addition of connecting plates and side pressure plates, the side pressure plates can not only apply downward pressure to the glass with a large contact area during use, but also adjust the downward pressure on the glass to a preset value. The preset pressure force ensures that the overall force on the glass is within the specified range, which facilitates polishing. 3. By setting a preset value during the polishing process, the preset value not only ensures that the glass will not be damaged by excessive pressure, but also ensures that the glass will not vibrate due to pressure below the preset value. 4. The adjusting component is designed to apply an upward lifting force or a downward dragging force to the side pressure plate to adapt to the reciprocating motion of the moving seat. Specifically, when the polishing wheel applies a downward cutting force to the glass edge, the adjusting component applies an upward lifting force to the side pressure plate; when the polishing wheel applies an upward cutting force to the glass edge, the adjusting component applies a downward dragging force to the side pressure plate. Combining these two situations, the adjusting component can counteract the cutting force applied to the glass by the reciprocating motion of the polishing wheel, ensuring that the glass as a whole is always subjected to a preset pressing force. 5. By including a controller and a power source in the adjustment component, when the first motor drives the polishing wheel to rotate, the corresponding signal command of the output shaft of the first motor can be transmitted to the controller as input, thereby causing the controller to control the power source to produce a corresponding lifting or dragging action. The present invention automatically changes the action force exerted by the power source on the glass according to the different movement directions of the polishing wheel, which is ingeniously designed. 6. With the crank-connecting rod structure, in operation, the power source will apply a lifting or dragging force to the second auxiliary arm. This lifting or dragging force is transmitted to the first auxiliary arm through the main arm and finally acts on the side pressure plate. The lifting or dragging force has a vertical upward or downward component. The component in this direction can be used to counteract the cutting force applied by the light wheel to the edge of the glass, ensuring that the overall force on the glass is controlled within the preset value. 7. By setting the lever arm from the first auxiliary arm to the upper fulcrum of the main arm to be smaller than the lever arm from the second auxiliary arm to the upper fulcrum of the main arm, under this design, the lifting or dragging tendency at the second auxiliary arm will be amplified to the first auxiliary arm, thereby maximizing the effect on the side pressure plate. In other words, the power source only needs to have a small energy tendency, which makes the power source more versatile and compact. 8. By setting the power source as an electromagnet, under the signal commands corresponding to the two directions of the first motor output shaft, the two sets of electromagnets will have a tendency to attract or repel each other. The two sets of electromagnets work together to cooperate with the crank connecting rod to perform lifting or dragging actions. 9. With the second motor and the assembly cylinder, the output shaft of the second motor is rotatably connected to the top of the polishing wheel, and the piston rod of the assembly cylinder is rotatably connected to the bottom of the polishing wheel. Both connections are detachable, which facilitates the disassembly and assembly of the polishing wheel. 10. By setting up the side cylinder and the flipping block, the presence of the flipping block can, on the one hand, expand the outer ring pressure area of ​​the side pressure plate so that when the glass size is larger than the bearing plate size, the whole composed of the side pressure plate and the flipping block can provide good surface contact pressure on the edge of the glass; on the other hand, the pressure of the flipping block on the glass makes the edge of the glass firmly pressed, which can accelerate the vertical upward movement rate of the polishing wheel, thereby improving the polishing efficiency.

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Example 1: like Figures 1-6 As shown, a large-size glass peripheral polishing machine includes a machine tool 1, a clamp for holding the surface of glass a, and a polishing assembly for polishing the edges of glass a. Figure 3 As shown, the fixture is positioned in the middle of the machine tool 1. In use, the fixture first clamps and fixes the surface of the glass a to be polished. This fixture can rotate the glass a horizontally. Then, the polishing assembly polishes the edges of the glass a. Specifically, the polishing assembly includes a base 2, a movable seat 3, a polishing wheel 4, and a drive component. The base 2 is mounted on the machine tool 1. The movable seat 3 is slidably mounted on the side of the base 2 facing the fixture. The polishing wheel 4 is rotatably mounted on the movable seat 3 and arranged vertically. The drive component is fixedly mounted on the base 2. The drive component drives the movable seat 3 to reciprocate along the rotation axis of the polishing wheel 4 on the base 2. Figure 3 As you can see, the reciprocating motion of polishing wheel 4 is a vertical reciprocating motion. For example... Figure 1 As shown, the base 2, the movable seat 3 and the polishing wheel 4 can be set as two sets, and the two sets are arranged in a relative manner. The fixture is located between the two sets. The polishing efficiency of glass a can be improved by using the two sets.

[0028] In the above-described polishing assembly design, after the glass a is clamped and fixed using a fixture, the polishing wheel 4 is driven to rotate. Simultaneously, a driving component drives the moving base 3 to reciprocate. This reciprocating movement of the moving base 3 causes the polishing wheel 4 to rotate while also reciprocating, thereby driving the base 2 to move towards the edge of the glass a until the polishing wheel 4 contacts the edge of the glass a, thus achieving polishing. Figures 1-3 as well as Figure 7 Taking the example shown, the rotation axis of the polishing wheel 4 is arranged along the vertical direction, and thus the reciprocating motion of the polishing wheel 4 is also along the vertical direction. That is, the motion trajectory of the polishing wheel 4 is a composite motion of rotation and reciprocating motion along the vertical direction. This invention utilizes this motion of the polishing wheel 4 to perform vertical up-and-down reciprocating polishing on the edge of glass a, resulting in good and uniform polishing effect, effectively solving the problem of heavy polishing marks left on the edge of glass a during the initial processing.

[0029] To ensure that the base 2 can smoothly move the polishing wheel 4 towards the edge of glass a, in this embodiment, a guide rail 13 is fixedly installed on the machine tool 1, and the base 2 is slidably mounted on the guide rail 13. A fourth motor (not shown in the figure) is also installed on the machine tool 1, and the output shaft of the fourth motor is fixedly equipped with a threaded rod (not shown in the figure). The base 2 is threaded onto the threaded rod, and thus the fourth motor can drive the threaded rod to rotate, thereby moving the base 2 along the guide rail 13, allowing the polishing wheel 4 to move closer to or further away from the edge of glass a. Meanwhile, as... Figure 1 and Figure 4 As shown, in order to improve the polishing effect on glass a during the polishing process, the present invention also includes two sets of nozzle assemblies 14 disposed on the movable seat 3, and the two sets of nozzle assemblies 14 are respectively located on both sides of the polishing wheel 4. The nozzle assemblies 14 can spray polishing liquid or water onto the polishing area at the edge of the polishing wheel 4 and the glass a.

[0030] Regarding the aforementioned driving component, the driving component includes a first motor 5 fixedly mounted on the base 2, and the output shaft of the first motor 5 is fixedly mounted with a reciprocating lead screw 6 arranged in the vertical direction. A connecting block 7 is threaded onto the reciprocating lead screw 6, and the connecting block 7 is fixedly connected to the movable seat 3. Thus, the first motor 5 can drive the reciprocating lead screw 6 to rotate, thereby realizing the sliding of the movable seat 3 on the base 2.

[0031] like Figures 1-2As shown, the fixture described above includes a third motor 10 mounted on the machine tool 1, a support plate 11 mounted on the output shaft of the third motor 10, and a top pressing component mounted on the machine tool 1 and located above the support plate 11. In use, glass a is placed on the support plate 11, and then the top pressing component is used to press the top of glass a. This top pressing component can be a telescopic rod or a hydraulic cylinder, preferably a pneumatic cylinder. When the top pressing component is set as a top pressing cylinder 12, a plunger is rotatably mounted on the piston rod of the top pressing cylinder 12. The plunger on the piston rod of the top pressing cylinder 12 can stably clamp glass a, and the plunger can rotate relative to the top pressing cylinder 12. Thus, the support plate 11, glass a, and plunger, after being clamped, can form a whole. The third motor 10 can drive the whole composed of the above three components to perform corresponding rotational actions. Combined with the polishing action of the polishing wheel 4, the edge of glass a can be circumferentially polished.

[0032] like Figure 5 As shown, to enable the polishing wheel 4 to be installed and rotated on the movable base 3, a second motor 8 and an assembly cylinder 9 are fixedly installed at the top and bottom of the movable base 3, respectively. The piston rod of the assembly cylinder 9 is coaxially arranged with the output shaft of the second motor 8. The top end of the polishing wheel 4 is fixedly connected to the output shaft of the second motor 8, and the bottom end of the polishing wheel 4 rotates and abuts against the piston rod of the assembly cylinder 9. Activating the second motor 8 will drive the polishing wheel 4 to rotate. Subsequently, by coordinating the vertical movement of the polishing wheel 4, the edge of glass a can be polished. To disassemble the polishing wheel 4, simply move the piston rod of the assembly cylinder 9 downwards to release it from contact with the bottom end of the polishing wheel 4, and then disconnect the top end of the polishing wheel 4 from the output shaft of the second motor 8.

[0033] like Figure 4 As shown, in order to prevent foreign objects such as dust from the external environment from interfering with the operation of the polishing wheel 4, the present invention also provides a protective cover 15 for covering the second motor 8 on the movable seat 3. Furthermore, in order to ensure the stable installation of the above-mentioned top pressure cylinder 12, a fixed bracket 16 can be separately set on the machine tool 1, and the top pressure cylinder 12 is fixedly installed on the fixed bracket 16.

[0034] The base 2, the movable seat 3, and the polishing wheel 4 are considered as a whole. The base 2 serves as the carrier of the movable seat 3, and the movable seat 3 serves as the carrier of the polishing wheel 4 and the second motor 8. Figures 1-3 Taking the example shown, the three components are fixed in position on the machine tool 1 to ensure that the polishing wheel 4 is arranged vertically, so that the polishing wheel 4 in this direction can perform vertical up-and-down polishing on the edge of the glass a in the horizontal position. This state can be achieved by... Figure 7 To represent, Figure 7In the diagram, line b represents the direction of the rotation axis of polishing wheel 4, and line b is arranged vertically. Line c represents the direction at the edge of glass a, and line c is arranged horizontally.

[0035] Example 2: like Figures 8-9 As shown in the above embodiment, the design for clamping and limiting glass a involves pressing glass a against the support plate 11 by a rotary plunger on the top-pressure cylinder 12. Subsequently, the support plate 11, glass a, and plunger form a rotatable whole. However, if the glass a is pressed against the support plate 11 solely by the plunger on the top-pressure cylinder 12, the contact area between the plunger and glass a is small. Consequently, during rotation, only the middle part of glass a is subjected to downward pressing force, while its edges are not subjected to any downward pressing force. When the whole consisting of the support plate 11, glass a, and plunger is driven to rotate and comes into contact with the polishing wheel 4 for processing, a small vibration may occur at the edge of glass a, thus affecting the polishing effect. Based on this, this embodiment adds a connecting plate 17 and two side pressure plates 18 to any of the above embodiments. Specifically, the connecting plate 17 is slidably mounted on the machine tool 1 in the vertical direction. The connecting plate 17 is located above the bearing plate 11 and is driven to move by a top pressure member. In this embodiment, the top pressure member is the top pressure cylinder 12 in Embodiment 1. The connecting plate 17 is rotatably mounted at the bottom end of the piston rod of the top pressure cylinder 12. The two side pressure plates 18 are respectively hinged to both sides of the connecting plate 17. Figure 8 As shown, the connecting plate 17 and the two side pressure plates 18 are arranged in a U-shape.

[0036] Based on the above design, in this embodiment, glass a is first placed on the support plate 11. Then, the top-pressure cylinder 12 drives the connecting plate 17 and the two side pressure plates 18 downward until the two side pressure plates 18 abut the top of glass a. At this time, the large-area contact between the side pressure plates 18 and the top of glass a, as well as the left-right layout of the side pressure plates 18, ensures that glass a is stably pressed down. Then, the piston rod of the top-pressure cylinder 12 is slowly driven to apply downward force. This downward force is applied to glass a through the two side pressure plates 18 until the downward pressing force on glass a reaches a preset value, so that glass a is stably pressed on the support plate 11. During the subsequent polishing process, glass a under this preset pressing force will not vibrate or be damaged. It should be noted that the hinge structure between the side pressure plates 18 and the connecting plate 17 can meet the requirement that the connecting plate 17 drives the side pressure plates 18 downward and abuts the glass a.

[0037] Example 3: In combination with the reciprocating motion characteristic of the polishing wheel 4 in the above embodiments, to Figure 7Taking the reciprocating motion of the polishing wheel 4 along the vertical direction as an example, when the polishing wheel 4 moves vertically upward, it applies an upward vertical force to the edge of glass a. Since the side pressure plate 18 in the above embodiment already applies a preset downward vertical pressure force to the entire glass a, the upward vertical force applied by the polishing wheel 4 to the edge of glass a will disrupt the force balance of the entire glass a, causing the net downward vertical pressure force on the entire glass a to be less than the preset value. During the polishing process, vibration may still occur at the edge of glass a. When the polishing wheel 4 moves vertically downward, it applies a downward vertical force to the edge of glass a. This force also disrupts the force balance of the entire glass a, causing the net downward vertical pressure force on the entire glass a to be greater than the preset value, which may then damage the glass a.

[0038] Based on this, this embodiment adds an adjusting component to the design of the aforementioned clamp. This adjusting component is used to apply a vertically upward lifting force or a vertically downward dragging force to the side pressure plate 18 to adapt to the reciprocating motion of the moving seat 3. Still using... Figure 7 Taking the reciprocating motion of the polishing wheel 4 along the vertical direction as an example, when the polishing wheel 4 moves vertically downward, that is, when the moving seat 3 drives the polishing wheel 4 to apply a vertically downward cutting force to the edge of glass a, the adjusting member is used to apply a vertically upward lifting force to the side pressure plate 18. This lifting force can counteract the vertically downward cutting force applied by the polishing wheel 4 to the edge of glass a, so that the vertically downward pressing force on the entire glass a tends to or is equal to the preset value. When the polishing wheel 4 moves vertically upward, that is, when the moving seat 3 drives the polishing wheel 4 to apply a vertically upward cutting force to the edge of glass a, the adjusting member is used to apply a vertically downward dragging force to the side pressure plate 18. This dragging force can counteract the vertically upward cutting force applied by the polishing wheel 4 to the edge of glass a, so that the vertically downward pressing force on the entire glass a tends to or is equal to the preset value.

[0039] Specifically, the adjusting component includes a controller (not shown in the figure), two sets of crank connecting rods 19 disposed opposite each other on the connecting plate 17, and two sets of power sources 20 disposed on the connecting plate 17. Both sets of power sources 20 are located between the two sets of crank connecting rods 19. The disjoint ends of the two sets of crank connecting rods 19 are hinged to the inner sides of the two side pressure plates 18, and the proximal ends of the two sets of crank connecting rods 19 are hinged to the actuating ends of the two sets of power sources 20. The driving component and the two sets of power sources 20 are electrically connected to the controller, and both sets of power sources 20 are controlled by the controller. It should be noted that the electrical connection between the driving component and the controller in this embodiment is intended to transmit different operating states of the driving component as corresponding input commands to the controller. The driving component will be equated with the first motor 5 in the following description.

[0040] In this embodiment, by setting the adjustment component, the two working states of the adjustment component are used to adapt to the reciprocating motion of the polishing wheel 4, so that the overall pressing force on the glass a tends to or is equal to the preset value, ensuring the stability of the glass a as a whole and providing good protection for the glass a, which is conducive to the polishing process.

[0041] Still with Figure 7 Taking the reciprocating motion of the polishing wheel 4 along the vertical direction as an example, the first motor 5 is used to drive the polishing wheel 4 to reciprocate along the vertical direction. When the polishing wheel 4 moves vertically downward, that is, when the polishing wheel 4 applies a vertically downward cutting force to the edge of the glass a, the signal command corresponding to the rotation direction of the output shaft of the first motor 5 at this time is input to the controller. After processing by the controller, the controller drives the power source 20 to work, so that the power source 20 applies a vertically upward lifting force to the side pressure plate 18 through the crank connecting rod 19. When the polishing wheel 4 moves vertically upward, that is, when the polishing wheel 4 applies a vertically upward cutting force to the edge of the glass a, the signal command corresponding to the rotation direction of the output shaft of the first motor 5 at this time is input to the controller. After processing by the controller, the controller drives the power source 20 to work, so that the power source 20 applies a vertically downward dragging force to the side pressure plate 18 through the crank connecting rod 19.

[0042] It should be noted that the specific structural configuration of the crank connecting rod 19 and the power source 20 can be a conventional technical means in the prior art, as long as the cooperation between the two can achieve the lifting or dragging force on the side pressure plate 18.

[0043] Example 4: This embodiment provides a detailed description of the preferred structure of the crank connecting rod 19 and the power source 20 in Embodiment 3: (a) Crank connecting rod 19, the crank connecting rod 19 includes a main arm 1901 rotatably mounted on the connecting plate 17, and a first auxiliary arm 1902 and a second auxiliary arm 1903 are respectively hinged at both ends of the main arm 1901. The first auxiliary arm 1902 is hinged to the inner side of the side pressure plate 18, and the second auxiliary arm 1903 is hinged to the actuating end of the power source 20. (1) Combination Figure 9 When the polishing wheel 4 moves vertically downward, the signal command corresponding to the rotation direction of the output shaft of the first motor 5 drives the two power sources 20 to move away from each other through the controller. At this time, the power source 20 will apply a lifting action to the second auxiliary arm 1903. This lifting action is transmitted to the first auxiliary arm 1902 through the main arm 1901 and finally acts on the side pressure plate 18. This lifting action has a vertically upward component. The vertically upward component can counteract the vertically downward cutting force applied by the polishing wheel 4 to the edge of the glass a. (2) Combination Figure 10When the polishing wheel 4 moves vertically upward, the signal command corresponding to the rotation direction of the output shaft of the first motor 5 drives the two power sources 20 to move closer to each other through the controller. At this time, the power source 20 will apply a dragging force to the second auxiliary arm 1903. This dragging force is transmitted to the first auxiliary arm 1902 through the main arm 1901 and finally acts on the side pressure plate 18. This dragging force has a vertically downward component. The effect of this vertically downward component can counteract the vertically upward cutting force applied by the polishing wheel 4 to the edge of the glass a. (3) Combination Figures 9-10 Based on the aforementioned crank-connecting rod 19 structure, to ensure that the lifting or dragging effect generated by the second auxiliary arm 1903 is amplified and transmitted to the first auxiliary arm 1902, and finally acts on the side pressure plate 18, the lever arm from the first auxiliary arm 1902 to the fulcrum of the main arm 1901 can be set to be smaller than the lever arm from the second auxiliary arm 1903 to the fulcrum of the main arm 1901. According to the lever principle, when the lever arm from the first auxiliary arm 1902 to the fulcrum of the main arm 1901 is smaller than the lever arm from the second auxiliary arm 1903 to the fulcrum of the main arm 1901, the lifting or dragging effect at the second auxiliary arm 1903 will be amplified to the first auxiliary arm 1902, thus maximizing its effect on the side pressure plate 18. Subsequently, only a low-power power source 20 is needed to meet the usage requirements.

[0044] (II) Power source 20: Based on the above-mentioned crank-connecting rod 19 structure, the power source 20 is preferably an electromagnet. Two sets of electromagnets work together, and when the output shaft of the first motor 5 has two rotation directions, the signal command corresponding to its rotation direction is transmitted to the controller. The controller then causes the two sets of electromagnets to have a tendency to attract or repel each other, in order to cooperate with the crank-connecting rod 19 to perform a lifting or dragging action. Of course, in some possible embodiments, the two sets of power sources 20 can also be set as cylinders or hydraulic cylinders. When the two sets of power sources 20 are set as double-headed cylinders, when the double-headed cylinder receives the corresponding signal command from the controller, the piston rods at both ends of the double-headed cylinder can simultaneously generate an extension or contraction tendency to counteract the cutting force generated by the polishing wheel 4 on the edge of the glass a. Of course, the power source 20 can also be set as a conventional single-headed cylinder. The two sets of power sources 20 need to be equipped with two sets of single-headed cylinders, which work independently and do not interfere with each other.

[0045] It should be noted that the input-output logic relationship between the signal commands corresponding to different directions of the output shaft of the first motor 5, the controller, and the power source 20 is a conventional technical setting in the prior art. This paper does not limit the construction of this logic relationship, as long as it ensures that the corresponding direction of the output shaft of the first motor 5 can control the power source 20 to generate a corresponding motion trend under the control of the controller. For example, when the output shaft of the first motor 5 rotates forward, the positive voltage signal generated is applied to the power source 20 through the controller, causing the power source 20 to perform a corresponding action trend; when the output shaft of the first motor 5 rotates in reverse, the negative voltage signal generated is applied to the power source 20 through the controller, causing the power source 20 to perform an action trend opposite to the aforementioned action trend.

[0046] Furthermore, the controller in this paper can be any applicable computing device, such as a personal computer, server, PLC controller, microcontroller, etc., or it can be an integration of computer devices. The controller has functions such as receiving information and sending control commands. The controller can control the power source 20 to perform corresponding actions through wired or wireless communication to counteract the cutting force applied by the polishing wheel 4 to the edge of the glass a.

[0047] Example 5: like Figures 11-12 As shown, based on the above embodiment 2, the fixture in this embodiment also includes a side cylinder 21 disposed on the outside of the side pressure plate 18 and a flipping block 22 hinged to the bottom side of the side pressure plate 18. The flipping block 22 is hinged to the piston rod of the side cylinder 21, and the flipping block 22 is located between the polishing wheel 4 and the side pressure plate 18. The side cylinder 21 is used to drive the flipping block 22 to press against or move away from the glass a, so as to adapt to the reciprocating motion of the polishing wheel 4.

[0048] Specifically, when the moving seat 3 drives the polishing wheel 4 to apply a vertically downward cutting force to the edge of glass a, the positive voltage signal corresponding to the downward rotation of the output shaft of the first motor 5 is transmitted to the controller. The controller acts on the side cylinder 21, causing the side cylinder 21 to drive the flipping block 22 away from glass a, preventing the flipping block 22 from exerting a pressing force on glass a and causing damage. This state can be controlled by... Figure 11 This can be represented as follows: When the moving seat 3 drives the polishing wheel 4 to apply a vertically upward cutting force to the edge of glass a, the negative voltage signal corresponding to the downward rotation of the output shaft of the first motor 5 is transmitted to the controller. The controller acts on the side cylinder 21, causing the side cylinder 21 to drive the flipping block 22 to press against the glass a. This state can be represented by... Figure 12 To express.

[0049] In this embodiment, by setting a side cylinder 21 and a flipping block 22, when the side cylinder 21 presses the flipping block 22 against the glass a, the presence of the flipping block 22 can, on the one hand, expand the outer ring pressing area of ​​the side pressure plate 18 so that when the size of the glass a is larger than the size of the support plate 11, the whole composed of the side pressure plate 18 and the flipping block 22 can provide good surface contact pressing at the edge of the glass a; on the other hand, by pressing the glass a with the flipping block 22, the edge of the glass a is firmly pressed, which can accelerate the vertical upward movement rate of the polishing wheel 4, thereby improving the polishing efficiency.

[0050] Example 6: This invention also proposes a control method for a large-size glass peripheral polishing machine, which includes the following steps: Step 1: Place glass a on the support plate 11 and use the top pressure member to drive the connecting plate 17 and the side pressure plate 18 to move vertically downward until the top of glass a is pressed down. At this time, the side pressure plate 18 will apply a vertical downward pressing force to glass a. The magnitude of the pressing force can be preset according to the type of glass a. Step 2: Use the second motor 8 to drive the polishing wheel 4 to rotate. At the same time, use the driving component to drive the polishing wheel 4 to reciprocate along its axis. Step 3: Use the fourth motor to drive the base 2 to move until the polishing wheel 4 on the base 2 comes into contact with the edge of the glass a; Step 4: Based on the direction of the cutting force applied by the polishing wheel 4 to the edge of glass a, the input command corresponding to the rotation direction of the output shaft of the first motor 5 is transmitted to the controller. After processing, the controller acts on the power source 20, so that the power source 20 applies force to the side pressure plate 18 by means of the crank connecting rod 19. If the direction of the cutting force applied by the polishing wheel 4 to the edge of glass a is vertically downward, the power source 20 applies a vertically upward lifting force to the side pressure plate 18 by means of the crank connecting rod 19. The magnitude of this vertically upward lifting force is the same as that of the vertically downward cutting force, so as to ensure that the vertically downward force on glass a is always the preset magnitude. If the direction of the cutting force applied by the polishing wheel 4 to the edge of glass a is vertically upward, the power source 20 applies a vertically downward dragging force to the side pressure plate 18 by means of the crank connecting rod 19. The magnitude of this vertically downward dragging force is the same as that of the vertically upward cutting force, so as to ensure that the vertically downward force on glass a is always the preset magnitude.

[0051] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
