Description

Technical Field

[0001] This invention relates to the field of glass processing technology, specifically to an automated double-sided polishing device and method for panel glass. Background Technology

[0002] In emerging fields such as consumer electronics, automotive displays, and building-integrated photovoltaics, panel glass is rapidly developing towards larger sizes, thinner profiles, and irregular shapes. To meet the stringent requirements of subsequent processes such as screen printing, coating, and lamination for surface roughness, parallelism, and edge integrity, both the top and bottom surfaces of the glass must be precision-polished simultaneously before leaving the factory.

[0003] However, existing grinding devices still have some shortcomings: Traditional solutions often employ a sequential process of "flipping—single-sided grinding—flipping again," which is not only time-consuming but also prone to secondary scratches, chipping, and thickness deviations during flipping and secondary clamping, making it difficult to meet the demands of high-speed, high-volume production. Ultra-thin glass is also highly susceptible to breakage due to localized stress concentration during clamping. Existing rigid clamps or vacuum adsorption methods are poorly adapted to glass warping and thickness fluctuations; excessive clamping force leads to breakage, while insufficient clamping force causes movement during grinding, affecting surface quality. To achieve simultaneous double-sided processing, some equipment uses two sets of sanding belts, but the vertical position of the sanding belts needs to be adjusted in real time according to the glass thickness. Traditional belt or gear drives are prone to sudden tension changes or disengagement during belt lifting, resulting in power interruption, uneven grinding texture, and in severe cases, burnt-out drive motors.

[0004] Therefore, the market urgently needs an automated device that can continuously feed online, adaptively clamp, perform simultaneous double-sided grinding, and transmit power without interruption, in order to solve the core pain points of low efficiency, low yield, and poor adaptability in existing technologies. Summary of the Invention

[0005] The purpose of this invention is to provide an automated double-sided polishing device and method for panel glass to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: An automated double-sided polishing device for panel glass includes a frame, two conveyor belts, and two clamping plates. The two conveyor belts are mounted on the frame via a drive mechanism. The drive mechanism can drive the panel glass to be conveyed along the length of the frame via the two conveyor belts. The two clamping plates are symmetrically slidably mounted on the frame along a direction perpendicular to the length of the frame, and the bottom surfaces of the two clamping plates are respectively in contact with the top surfaces of the two conveyor belts. The frame is equipped with two sets of grinding components, which are symmetrically arranged vertically around the conveyor belt. The frame is also equipped with two sets of elastic clamping mechanisms, which are symmetrically arranged along the length of the frame and connected to two clamping plates and two sets of grinding components, respectively. When the two sets of elastic clamping mechanisms are in operation, the two clamping plates move closer to each other and clamp and fix the panel glass on the two conveyor belts. At the same time, the two sets of grinding components also move closer to each other and fit against both sides of the panel glass. The frame is equipped with a transmission mechanism, which is connected to two sets of grinding components. When the transmission mechanism is running, the two sets of grinding components will simultaneously grind both sides of the panel glass. When the two sets of grinding components move in the vertical direction, the transmission mechanism can always maintain power transmission to the two sets of grinding components.

[0007] As a further aspect of the present invention: the driving mechanism includes a driving roller and a driven roller, which are respectively horizontally rotatably disposed at both ends of the frame; The two conveyor belts are installed on the outer walls of the drive roller and the driven roller, and are symmetrically distributed along the length direction perpendicular to the frame.

[0008] As a further embodiment of the present invention: a first motor is provided on the frame, and a No. 1 pulley is coaxially provided at one end of the drive roller shaft; The output end of the first motor is coaxially provided with a second pulley, and the first pulley and the second pulley are connected by a first toothed belt.

[0009] As a further embodiment of the present invention: the grinding assembly includes a guide seat and a frame, the guide seat is disposed on the frame, and the frame is vertically slidably disposed on the guide seat; The frame is equipped with rollers at all four corners for horizontal rotation, and sanding belts are installed on the outer walls of the four rollers.

[0010] As a further embodiment of the present invention: the elastic clamping mechanism includes a movable frame, a limiting post and a connecting rod, one end of the limiting post is fixedly connected to the side wall of the frame, and the movable frame is horizontally slidably disposed on the limiting post; The two ends of the connecting rod are rotatably connected to the frame and the movable frame, respectively, and the connecting rod is inclined. When the movable frame moves horizontally toward the frame, the connecting rod will drive the frame to move vertically toward the conveyor belt.

[0011] As a further embodiment of the present invention: the elastic clamping mechanism further includes a sleeve and a slide rod that slides with the sleeve, the sleeve being horizontally disposed on the movable frame, and one end of the slide rod being horizontally fixedly connected to the clamping plate; The sleeve is equipped with a spring inside, and the two ends of the spring abut against the inner side wall of the sleeve and the other end of the slide rod, respectively. An electric push rod is horizontally mounted on the frame, and the output end of the electric push rod is fixedly connected to the movable frame.

[0012] As a further embodiment of the present invention: the transmission mechanism includes two sets of adaptive structures and a power transmission structure. The adaptive structure includes a pin, a first rotating rod, and a second rotating rod. One end of the first rotating rod and the second rotating rod are rotatably connected to the pin. A drive shaft is horizontally rotatably mounted on the frame. The other end of the first rotating rod is rotatably connected to the drive shaft, and the other end of the second rotating rod is rotatably connected to one of the rollers.

[0013] As a further embodiment of the present invention: a third pulley is coaxially arranged on the transmission shaft, a fourth pulley is coaxially arranged on the pin shaft, and the third pulley and the fourth pulley are connected by a second toothed belt; A No. 5 pulley is coaxially mounted on the pin shaft, and a No. 6 pulley is coaxially mounted on one of the roller shafts. The No. 5 pulley and the No. 6 pulley are connected by a third toothed belt.

[0014] As a further embodiment of the present invention: the power transmission structure includes a second motor and two No. 7 pulleys, the second motor is mounted on the frame, and the output end of the second motor is coaxially and fixedly connected to one end of one of the transmission shafts; The two No. 7 pulleys are coaxially mounted on the two drive shafts, and the two No. 7 pulleys are connected by a fourth toothed belt.

[0015] A polishing method using an automated double-sided polishing device for panel glass as described above includes the following steps: Step 1: Loading and positioning. The glass is placed on the conveyor belt. The first motor drives the active roller through the pulley to smoothly feed the glass to the position of the workstation sensor, and then decelerates and stands by to complete the online positioning. Step 2: Clamping and bonding, the electric push rod extends, the moving frame moves inward, and the clamping spring presses the glass edge; the connecting rod presses down synchronously, so that the upper and lower sanding belts are bonded to both sides of the glass and maintain constant pressure; Step 3: Double-sided grinding. The second motor synchronously drives the sanding belts in a high-speed circumferential motion via two shafts and four belts. The parallel four-link linkage adaptively maintains the tension, and the upper and lower sanding belts grind both sides of the glass at a constant speed to the set roughness. Step 4: Release the clamp, the motor stops, the push rod retracts, the clamp is released, the sanding belt and frame retract, and the conveyor belt delivers the finished product and connects it to the next piece, realizing continuous automated operation.

[0016] Compared with the prior art, the beneficial effects of the present invention are: Through the linkage design of dual conveyor belts and elastic clamping mechanism, precise positioning and clamping of the panel glass are achieved during the conveying process, avoiding errors caused by traditional manual intervention. The symmetrically arranged grinding components adapt to both sides of the glass under the drive of the elastic clamping mechanism. With the continuous power transmission of the transmission mechanism, double-sided grinding can be completed simultaneously, improving processing efficiency and surface quality consistency. At the same time, the elastic clamping mechanism can dynamically balance the clamping force when clamping the glass to prevent the thin glass from breaking. The transmission mechanism maintains power connection during the vertical adjustment of the grinding components, ensuring continuous and stable operation, which is suitable for large-scale automated production scenarios.

[0027] 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.

[0028] Furthermore, elements in this invention are referred to as being "fixed to" or "set on" another element, which may be directly on the other element or may also include an intervening element. When an element is considered to be "connected" to another element, it may be directly connected to the other element or may also include an intervening element. The terms "vertical," "horizontal," "left," "right," and similar expressions used herein are for illustrative purposes only and do not represent the only possible implementations.

[0029] Please see Figures 1-9 In this embodiment of the invention, an automated double-sided polishing device for panel glass includes a frame 1, two conveyor belts 2 and two clamping plates 3. The two conveyor belts 2 are mounted on the frame 1 via a drive mechanism. The drive mechanism can drive the panel glass to be conveyed along the length direction of the frame 1 via the two conveyor belts 2. The two clamping plates 3 are symmetrically slidably mounted on the frame 1 along a direction perpendicular to the length direction of the frame 1, and the bottom surfaces of the two clamping plates 3 are respectively in contact with the top surfaces of the two conveyor belts 2. Two sets of grinding components are provided on the frame 1. The two sets of grinding components are symmetrically arranged vertically around the conveyor belt 2. Two sets of elastic clamping mechanisms are provided on the frame 1. The two sets of elastic clamping mechanisms are symmetrically arranged along the length direction perpendicular to the frame 1. The two sets of elastic clamping mechanisms are respectively connected to the two clamping plates 3 and the two sets of grinding components. When the two sets of elastic clamping mechanisms are running, the two clamping plates 3 move closer to each other and clamp and fix the panel glass on the two conveyor belts 2. At the same time, the two sets of grinding components will also move closer to each other and fit against both sides of the panel glass. The frame 1 is equipped with a transmission mechanism, which is connected to two sets of grinding components. When the transmission mechanism is running, the two sets of grinding components will simultaneously grind both sides of the panel glass. When the two sets of grinding components move in the vertical direction, the transmission mechanism can always maintain power transmission to the two sets of grinding components.

[0030] In this scheme, the drive mechanism drives two parallel conveyor belts 2 to run continuously along the length of the frame 1, feeding the panel glass into the grinding station at a stable speed; at this time, the clamping plate 3 is in contact with the top surface of the conveyor belt 2, keeping it in an "open" state and not interfering with the glass's forward movement. When the glass reaches the predetermined position, the elastic clamping mechanism is activated, which drives the two clamping plates 3 to slide synchronously along the length direction perpendicular to the frame 1, and flexibly clamps the two edges of the glass; the clamping force is adaptively adjusted by the elastic element, which ensures both positioning accuracy and prevents the ultra-thin glass from breaking. The same set of actions of the elastic clamping mechanism synchronously drives the upper and lower grinding components through the linkage mechanism. While the clamping plate 3 clamps the glass, the two grinding components move towards each other in the vertical direction until the upper sanding belt 13 presses against the upper surface of the glass and the lower sanding belt 13 presses against the lower surface of the glass, completing the "zero gap" bonding. The bonding pressure is indirectly set by the pre-tightening force of the elastic clamping mechanism to ensure uniformity. The transmission mechanism continuously transmits power to the upper and lower grinding components simultaneously, and the sanding belt 13 rotates to achieve synchronous grinding of both sides of the glass. If the height of the sanding belt 13 needs to be adjusted due to fluctuations in glass thickness or changes in specifications, the transmission mechanism can always maintain power connection when the grinding components are displaced in the vertical direction to ensure continuous and stable operation.

[0031] After grinding is completed, the elastic clamping mechanism reverses its movement, the clamping plate 3 is released, and the grinding components retract synchronously; the conveyor belt 2 continues to run, sending the double-sided finely ground glass out of the workstation, and the next piece of glass immediately enters, realizing continuous operation.

[0032] Please see Figure 1 , Figure 2 and Figure 7The drive mechanism includes a drive roller 4 and a driven roller 5, which are horizontally rotatably mounted at both ends of the frame 1. The two conveyor belts 2 are installed on the outer walls of the driving roller 4 and the driven roller 5, and are symmetrically distributed along the length direction perpendicular to the frame 1; The frame 1 is equipped with a first motor 6, and a pulley 7 is coaxially mounted on one end of the drive roller 4. The output end of the first motor 6 is coaxially provided with a second pulley 8, and the first pulley 7 and the second pulley 8 are connected by a first toothed belt 9.

[0033] In this embodiment, the first motor 6 is fixedly mounted on the frame 1, and its output shaft is coaxially connected to the second pulley 8; after the motor is powered on, the second pulley 8 rotates at a constant speed, providing the original power for the entire system; The second pulley 8 transmits torque to the first pulley 7 without slippage through the first toothed belt 9. Due to the meshing characteristics of the toothed belt, the speed and phase are precisely synchronized, avoiding the slippage or lag that may occur with traditional flat belts. The first pulley 7 is coaxially fixed to the drive roller 4, so the drive roller 4 starts to rotate at a speed with a fixed reduction ratio to the motor output shaft; at the same time, the driven roller 5 only provides passive support and rotates synchronously with the drive roller 4 under the traction of the two conveyor belts 2, forming a continuously rotating "roller-belt" closed loop. Two conveyor belts 2 are symmetrically tensioned on the outer walls of the drive roller 4 and the driven roller 5 along the length direction perpendicular to the frame 1; the rotation of the drive roller 4 directly drives the two conveyor belts 2 to move at the same linear speed and in the same direction, so as to realize the stable and synchronous conveying of the panel glass along the length direction of the frame 1.

[0034] Please see Figure 3 The grinding assembly includes a guide seat 10 and a frame 11. The guide seat 10 is disposed on the frame 1, and the frame 11 is vertically slidably disposed on the guide seat 10. The four corners of the frame 11 are each equipped with a horizontally rotating roller 12, and the outer walls of the four rollers 12 are fitted with sanding belts 13.

[0035] In this embodiment, the guide seat 10 is fixed on the frame 1 to provide a vertical slide rail for the frame 11; when the elastic clamping mechanism is activated, the frame 11 slides up and down along the guide seat 10, so that the pressure between the sanding belt 13 and the glass surface is precisely set and kept constant. A horizontally arranged roller 12 is installed at each of the four corners of the frame 11, at least one of which is a driving roller; the driving roller rotates after receiving continuous power input from the transmission mechanism, driving the other three driven rollers to rotate synchronously, forming a closed rotary path; The sanding belt 13 is tensioned on the outer wall of the four rollers 12 and moves synchronously and at high speed in a circular motion with the rollers 12. When the glass is transported to the grinding station and clamped and fixed, the high-speed running sanding belt 13 forms a relative linear velocity difference with the upper (or lower) surface of the glass, producing a continuous and uniform grinding effect, and realizing double-sided synchronous fine grinding.

[0036] Please see Figure 3 and Figure 6 The elastic clamping mechanism includes a movable frame 14, a limiting post 15, and a connecting rod 16. One end of the limiting post 15 is fixedly connected to the side wall of the frame 1, and the movable frame 14 is horizontally slidably disposed on the limiting post 15. The two ends of the connecting rod 16 are rotatably connected to the frame 11 and the movable frame 14 respectively, and the connecting rod 16 is inclined. When the movable frame 14 moves horizontally toward the frame 1, the connecting rod 16 will drive the frame 11 to move vertically toward the conveyor belt 2. The elastic clamping mechanism further includes a sleeve 17 and a slide rod 18 that slides with the sleeve 17. The sleeve 17 is horizontally arranged on the movable frame 14, and one end of the slide rod 18 is horizontally fixedly connected to the clamping plate 3. A spring 19 is provided inside the sleeve 17, and the two ends of the spring 19 abut against the inner side wall of the sleeve 17 and the other end of the slide rod 18, respectively. An electric push rod 20 is horizontally arranged on the frame 1, and the output end of the electric push rod 20 is fixedly connected to the movable frame 14.

[0037] In this embodiment, the electric push rod 20 is horizontally fixed on the frame 1, and its output end is fixedly connected to the movable frame 14; when the push rod extends or retracts, it directly drives the movable frame 14 to make a precise horizontal linear movement along the limiting post 15. The limiting post 15 restricts the movable frame 14 to slide only along the direction perpendicular to the length of the frame 1 (i.e., the glass width direction); therefore, the extension and retraction of the push rod is completely converted into the horizontal displacement of the movable frame 14, without any offset. The two ends of the connecting rod 16 are hinged to the moving frame 14 and the frame 11 respectively and are arranged at an angle. When the moving frame 14 moves horizontally closer to the center of the frame 1, the angle of inclination of the connecting rod 16 decreases, generating a downward component force, which drives the frame 11 to move vertically along the guide seat 10 towards the conveyor belt 2, so that the sanding belt 13 presses against the glass surface. Conversely, when the moving frame 14 moves outward, the frame 11 is lifted and the sanding belt 13 is separated from the glass. The sleeve 17 is fixed on the movable frame 14. One end of the slide rod 18 is fixed to the clamping plate 3, and the other end extends into the sleeve 17 and compresses the spring 19. When the movable frame 14 continues to move inward and the clamping plate 3 contacts the edge of the glass, the slide rod 18 slides relative to the sleeve 17 and further compresses the spring 19. The spring force is balanced with the thrust of the electric push rod 20, forming a constant and finely adjustable elastic clamping force, which ensures the glass positioning and prevents the ultra-thin glass from breaking.

[0038] Please see Figure 5 , Figure 8 and Figure 9 The transmission mechanism includes two sets of adaptive structures and a power transmission structure. The adaptive structure includes a pin 21, a first rotating rod 22, and a second rotating rod 23. One end of the first rotating rod 22 and the second rotating rod 23 are rotatably connected to the pin 21. A drive shaft 24 is horizontally rotatably mounted on the frame 1. The other end of the first rotating rod 22 is rotatably connected to the drive shaft 24, and the other end of the second rotating rod 23 is rotatably connected to one of the rollers 12. A third pulley 25 is coaxially mounted on the drive shaft 24, and a fourth pulley 26 is coaxially mounted on the pin shaft 21. The third pulley 25 and the fourth pulley 26 are connected by a second toothed belt 27. A fifth pulley 28 is coaxially arranged on the pin 21, and a sixth pulley 29 is coaxially arranged on one of the rollers 12. The fifth pulley 28 and the sixth pulley 29 are connected by a third toothed belt 30. The power transmission structure includes a second motor 32 and two No. 7 pulleys 31. The second motor 32 is mounted on the frame 1, and the output end of the second motor 32 is coaxially and fixedly connected to one end of one of the transmission shafts 24. The two No. 7 pulleys 31 are coaxially mounted on the two transmission shafts 24, and the two No. 7 pulleys 31 are connected by a fourth toothed belt 33.

[0039] In this embodiment, the second motor 32 is fixed on the frame 1, and its output shaft is coaxially connected to one of the transmission shafts 24. After the motor is started, the transmission shaft 24 obtains a constant speed and becomes the main power source of the whole mechanism. Each of the two drive shafts 24 is equipped with a No. 7 pulley 31, and the two are connected by a fourth toothed belt 33. When the main drive shaft 24 rotates, the same speed and phase are transmitted to the other drive shaft 24 without slippage through the fourth toothed belt 33, so as to realize the synchronous drive of the upper and lower grinding head systems. An adaptive structure is arranged between each drive shaft 24 and its corresponding roller 12: First stage: Drive shaft 24 → No. 3 pulley 25 → Second toothed belt 27 → No. 4 pulley 26 → Pin 21; Second stage: Pin 21 → No. 5 pulley 28 → Third toothed belt 30 → No. 6 pulley 29 → Roller 12; The pin 21 forms a parallel four-bar adaptive mechanism through the first rotating rod 22 (hinged to the transmission shaft 24) and the second rotating rod 23 (hinged to the roller 12); when the frame 11 is raised and lowered with the elastic clamping mechanism, the spatial position of the pin 21 changes accordingly, the angle of the rotating rod is adjusted in real time, but the center distance of the pulley remains constant, and the second toothed belt 27 and the third toothed belt 30 are always in the correct meshing state, without slipping or skipping teeth; Regardless of how the frame 11 moves vertically, the adaptive structure ensures that the power chain from the drive shaft 24 to the roller 12 is uninterrupted, so that the sanding belt 13 always runs stably at the set linear speed, achieving continuous and uniform grinding of both sides of the panel glass.

[0040] A polishing method using an automated double-sided polishing device for panel glass as described above includes the following steps: Step 1: Loading and positioning. The glass is placed on the conveyor belt. The first motor drives the active roller through the pulley to smoothly feed the glass to the position of the workstation sensor, and then decelerates and stands by to complete the online positioning. Step 2: Clamping and bonding, the electric push rod extends, the moving frame moves inward, and the clamping spring presses the glass edge; the connecting rod presses down synchronously, so that the upper and lower sanding belts are bonded to both sides of the glass and maintain constant pressure; Step 3: Double-sided grinding. The second motor synchronously drives the sanding belts in a high-speed circumferential motion via two shafts and four belts. The parallel four-link linkage adaptively maintains the tension, and the upper and lower sanding belts grind both sides of the glass at a constant speed to the set roughness. Step 4: Release the clamp, the motor stops, the push rod retracts, the clamp is released, the sanding belt and frame retract, and the conveyor belt delivers the finished product and connects it to the next piece, realizing continuous automated operation.
