Description

Technical Field

[0001] The invention relates to the technical field of glass substrate grinding, and in particular to a glass substrate grinding device. Background Art

[0002] ‌The main function of edge grinding of glass substrates is to remove the sharp edges and corners caused by cutting to prevent scratches during use, eliminate local stress concentration, increase the strength of glass, and control the convexity and flatness of the substrate and improve the parallelism of the upper and lower surfaces. ‌During the production process of glass substrates, the edges may form sharp edges and corners due to cutting. These edges and corners may not only scratch people during use, but also form small cracks and microcracks on the edges of the glass, leading to local stress concentration. Through edge grinding, these sharp edges and corners can be effectively ground off and microcracks can be eliminated, thereby improving the strength and durability of the glass. In addition, the geometric dimension tolerance of the ground glass meets the requirements, ensuring the quality and consistency of the glass substrate. This treatment method not only performs different grades of quality processing on the glass edge, such as grinding into coarse grinding, fine grinding and polishing, but also improves the safety and performance of the glass substrate.‌

[0017] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0018] In order to solve the technical problem that the fixing and turning of the glass substrate are both manually operated and the processing efficiency is low, the present invention provides a glass substrate grinding device, which can realize rapid turning and fixing of the glass substrate so as to perform double-sided grinding on the glass substrate, which is beneficial to improving the processing efficiency of the glass substrate.

[0019] See also Figures 1 to 11The grinding device for a glass substrate comprises: a conveying mechanism 1, a grinding mechanism 2, a flipping mechanism 3 and an adjusting and fixing mechanism 4. The conveying channel of the conveying mechanism 1 is respectively formed with a transmission area and an operation area arranged in parallel; the grinding mechanism 2 is installed on one side of the conveying channel; the flipping mechanism 3 comprises a flipping driving member 33 and a flipping member 31 and a receiving member 32 rotatably arranged in the operation area, the flipping driving member 33 is used to drive the flipping member 31 and the receiving member 32 to rotate upward around one adjacent end respectively, so as to support and flip the glass substrate 6 backward through the flipping member 31, and receive and lower the flipped glass substrate 6 backward through the receiving member 32; the pressing end of the adjusting and fixing mechanism 4 corresponds to the conveying channel, and is used to move downward to press the glass substrate 6.

[0020] In this solution, a transmission area and an operation area arranged in parallel are formed at the conveying channel of the conveying mechanism 1, and the transmission area is used to provide power for conveying the glass substrate 6 so that the glass substrate 6 is conveyed in the conveying channel. When conveying, the glass substrate 6 will pass through the operation area. The turning member 31 and the receiving member 32 are both rotatably arranged in the operation area. When the glass substrate 6 is conveyed, the turning member 31 and the receiving member 32 can contact the part of the glass substrate 6 arranged in the operation area. Under the drive of the turning driving member 33, the turning member 31 can rotate upward around one end close to the receiving member 32. The receiving member 32 can rotate upward around one end close to the flipping member 31, so that the flipping member 31 can support the glass substrate 6 and flip it backward when it rotates. Then, the rotating receiving member 32 is used to receive and lower the flipped glass substrate 6, thereby realizing the flipping of the glass substrate 6. The pressing end of the adjusting mechanism 4 corresponds to the conveying channel, and the pressing end can move downward until it is pressed on the glass substrate 6 in the conveying channel, thereby realizing the pressing and fixing of the glass substrate 6, so that the set grinding mechanism 2 can grind the edge of the glass substrate 6 on one side of the conveying channel.

[0021] In order to realize the conveying of the glass substrate 6 so as to perform continuous feeding and grinding, in this embodiment, please refer to Figures 1 to 3 The conveying mechanism 1 includes a frame 11 and a plurality of rollers 12. The plurality of rollers 12 are sequentially arranged at the top center of the frame 11 along the length direction of the frame 11. A transmission area is formed above the plurality of rollers 12.

The driving shaft of the conveying motor is connected to the rollers 12 for driving the rollers 12 to rotate. The plurality of rollers 12 are sequentially connected by belts so that the plurality of rollers 12 can rotate synchronously in the same direction to convey the glass substrate 6 placed on the rollers 12.

[0022] In order to achieve the grinding of the glass substrate 6, in this embodiment, refer to Figure 2The grinding mechanism 2 includes a height-adjusting cylinder 21, a grinding wheel 22 and an electric guide rail 23. The electric guide rail 23 is mounted on the frame 11. The grinding wheel 22 is mounted on the bottom end of the height-adjusting cylinder 21. The top end of the height-adjusting cylinder 21 is mounted on the electric guide rail 23. The electric guide rail 23 can drive the grinding wheel 22 to move forward and backward above the conveying mechanism 1, so as to adjust the position of the grinding wheel 22 according to the edge position of the glass substrate 6. The height-adjusting cylinder 21 is used to drive the grinding wheel 22 to move up and down through telescopic movement to adjust the height of the grinding wheel 22 so that the grinding wheel 22 can grind the edge of the glass substrate 6.

[0023] Further, in one embodiment, see Figure 2 The grinding mechanism 2 also includes a measuring piece 24, which is used to obtain imaging information of the edge of the glass substrate 6, so as to control the height adjustment cylinder 21 according to the measurement data to adjust the grinding depth, so as to more accurately control the grinding accuracy. There are multiple measuring pieces 24 and grinding wheels 22, which are arranged in sequence along the conveying direction of the conveying channel, so that the edge of the glass substrate 6 can be detected and ground at one time, which is conducive to improving efficiency; wherein, the measuring piece 24 can be a shooting structure or a distance sensing structure, etc., which is a prior art.

[0024] In order to realize the turning over of the glass substrate 6, in this embodiment, please refer to Figure 3 , Figures 5 to 8 The material turning member 31 includes a material turning rod 311 , the material receiving member 32 includes a material receiving rod 321 , and the flipping driving member 33 includes a driving motor, a rotating shaft 331 , a driving rod 332 , a first connecting rod 333 , and a second connecting rod 334 .

[0025] Among them, one end of the material turning rod 311 close to the material receiving rod 321 is rotatably connected to the frame 11 of the conveying mechanism 1; one end of the material receiving rod 321 close to the material turning rod 311 is rotatably connected to the frame 11 of the conveying mechanism 1; a mounting groove 111 is provided on the side of the frame 11, so that the mounting groove 111 forms the operating area for installing the material turning piece 31 and the material receiving piece 32, so that the material turning piece 31 and the material receiving piece 32 cooperate to turn over the glass substrate 6. The rotating shaft 331 is rotatably installed inside the frame 11 and is connected to the driving shaft of the driving motor. The driving rod 332 is set in the installation groove 111 to be fixed on one end of the rotating shaft 331. One end of the driving rod 332 is connected to the material turning rod 311 through the first connecting rod 333, and the two ends of the first connecting rod 333 are rotatably connected to the driving rod 332 and the material turning rod 311 respectively. The other end of the driving rod 332 is connected to the material receiving rod 321 through the second connecting rod 334, and the two ends of the second connecting rod 334 are rotatably connected to the driving rod 332 and the material receiving rod 321 respectively.

[0026] See also Figure 7 and Figure 8 , Figure 7 The state of the flipping mechanism 3 before flipping the glass substrate 6. Figure 8 The turning mechanism 3 is in the state of turning over the glass substrate 6. During the implementation process, when the glass substrate 6 needs to be turned over, the driving motor drives the rotating shaft 331 and the driving rod 332 to rotate counterclockwise. When rotating, the turning rod 311 and the receiving rod 321 are synchronously driven by the first connecting rod 333 and the second connecting rod 334, so as to drive the right end of the turning rod 311 to rotate clockwise downward, so that the left end of the turning rod 311 rotates upward around the right end. When the left end rotates upward, it will contact the glass substrate 6 on the roller 12. When it continues to rotate, it can prop up the glass substrate 6 and drive the glass substrate 6 to turn to the right. At the same time, under the connection of the second connecting rod 27, the driving rod 332 drives the left end of the material receiving rod 321 to rotate counterclockwise downward, so that the right end of the material receiving rod 321 rotates counterclockwise upward around the left end, which corresponds to the flipped material turning rod 311. After the flipping material turning rod 311 flips more than 90 degrees, the glass substrate 6 falls from the flipping material turning rod 311 to the material receiving rod 321, and then the driving motor drives the rotating shaft 331 and the driving rod 332 to rotate clockwise, driving the flipping material turning rod 311 and the material receiving rod 321 to reset. When the material receiving rod 321 is reset, the glass substrate 6 is placed on the roller 12, thereby realizing the flipping of the glass substrate 6.

[0027] In order to prevent the glass substrate 6 from falling between the turning rod 311 and the receiving rod 321 during turning over, resulting in a turning failure, in one embodiment, the turning rod 311 and the receiving rod 321 are provided with protrusions on their upper parts to form a first protrusion 312 and a second protrusion 322 respectively. During turning over, the first protrusion 312 and the second protrusion 322 can support the side of the glass substrate 6 to prevent the glass substrate 6 from falling.

[0028] In order to prevent the turning rod 311 and the receiving rod 321 from colliding with the glass substrate 6 and scratching the glass substrate 6 when turning over, in one embodiment, the upper surfaces of the turning rod 311 and the receiving rod 321 are respectively provided with a first protective strip 313 and a second protective strip 323, and the first protective strip 313 and the second protective strip 323 are both made of rubber material to play a protective role.

[0029] In order to improve the stability of the glass substrate 6 during the flipping process, in this embodiment, mounting grooves 111 are provided on both sides of the transmission area, so that the operation area is provided with two, which are respectively located on both sides of the plurality of rollers 12. Therefore, the flipping member 31 and the receiving member 32 are provided with two, and are respectively arranged in the two operation areas. The two flipping members 31 are arranged in a mirror image with the center line of the conveying mechanism as the reference, and the two receiving members 32 are also arranged in a mirror image with the center line of the conveying mechanism as the reference. There are two driving rods 332, first connecting rods 333 and second connecting rods 334. The two driving rods 332 are respectively fixedly mounted on the two ends of the rotating shaft 331. The turning rod 311 and the receiving rod 321 in the corresponding mounting groove 111 are connected through the first connecting rod 333 and the second connecting rod 334. The two turning parts 31 and the two receiving parts 32 can be driven to move synchronously by the turning driving part 33, so that the two turning rods 311 and the receiving rod 321 can be supported on both sides of the glass substrate 6 during the turning operation, and the stability is higher.

[0030] Preferably, in this embodiment, please refer to Figure 1 , Figure 2 , Fig. 9 and Fig.10 The fixing mechanism 4 includes a fixing frame 41, a positioning driving member 42, a lifting driving member 43, a rotating driving member 44 and a fixing assembly 45. The fixing frame 41 is mounted on the conveying passage and is fixedly connected to the frame 11 by bolts or welding. The positioning driving member 42 is installed on the fixing frame 41. The fixing assembly 45 is connected with the rotating driving member 44, the lifting driving member 43 and the positioning driving member 42 in sequence. The rotating driving member 44 is used to drive the fixing assembly 45 to rotate. The lifting driving member 43 is used to drive the fixing assembly 45 to move up and down, so that when the fixing assembly 45 moves downward, the glass substrate 6 on the roller 12 can be pressed and fixed, and when the fixing assembly 45 moves upward, the glass substrate 6 can be loosened. The positioning driving member 42 is used to drive the fixing assembly 45 to move horizontally along the conveying passage, so that the fixing assembly 45 corresponds to the positions before and after the glass substrate 6 is turned over.

[0031] In one preferred embodiment, see Fig. 9 and Fig.10The fixing assembly 45 includes a mounting frame 451, a rotating drum 452, a connecting belt 453 and a positioning motor 454. The mounting frame 451 is fixedly connected to the driving end of the rotating driving member 44. A plurality of rotating drums 452 are sequentially arranged at the bottom of the mounting frame 451. The rotating drums 452 are rotatably connected to the mounting frame 451. The connecting belt 453 is sleeved between the plurality of rotating drums 452. When the fixing assembly 45 moves downward, the connecting belt 453 contacts the glass substrate 6 to achieve the pressing and fixing of the glass substrate 6. The positioning motor 454 is connected to one of the rotating drums 452 to pass The driving drum 452 rotates to drive the connecting belt 453 to move on the drum 452 to push the glass substrate 6 on the conveying channel; wherein, the driving direction of the fixing assembly 45 is perpendicular to the conveying direction of the conveying mechanism 1, so that the conveying mechanism 1 can adjust the left and right position of the glass substrate 6 by conveying the glass substrate 6, and the fixing assembly 45 can adjust the front and rear position of the glass substrate 6. Specifically, the grinding mechanism 2 is arranged at the rear of the conveying mechanism 1, so that the edge of the glass substrate 6 can be pushed to the bottom of the grinding mechanism 2 by using the fixing assembly 45, so as to achieve the purpose of adjusting the position of the glass substrate 6.

[0032] The positioning drive 42 includes a first guide rail, a first motor, a screw and a sleeve. The first guide rail is fixedly connected to the fixed frame 41.

The sleeve is also connected to the lifting drive 43. The first motor is connected to one end of the screw to drive the screw to rotate, so as to drive the sleeve to slide in the first guide rail along the length direction of the guide rail. The fixing assembly 45 is driven to move left and right by the lifting drive 43 and the rotating drive 44, so that the fixing assembly 45 corresponds to the position before and after the glass substrate 6 is turned over, respectively, and can fix the glass substrate 6 before and after the flipping.

[0033] The lifting drive member 43 includes a third lifting cylinder, and the third lifting cylinder is fixedly connected to the sleeve through a mounting plate; the rotating drive member 44 includes a second motor, and the second motor is connected to the driving end of the third lifting cylinder. Specifically, the second motor is installed in a motor box, and the motor box is fixed at the driving end of the bottom of the third lifting cylinder.

[0034] It should be noted that, in this solution, at least one end of the first guide rail extends to the outside of the top of the flipping mechanism, so that the fixing assembly 45 can be moved to the outside of the position before and after the glass substrate 6 is flipped under the drive of the positioning drive 42, without affecting the flipping of the glass substrate 6.

[0035] Since the rotating drive member 44 is provided, the second motor can drive the fixing assembly 45 to rotate, thereby driving the glass substrate 6 to rotate 90 degrees, so as to grind the four edges of the glass substrate 6 in sequence. In order to ensure that the fixing assembly 45 can drive the glass substrate 6 to rotate when rotating, please refer to Figure 3 The conveying mechanism 1 further includes a first supporting assembly 13 and a second supporting assembly 14, which are respectively arranged between two of the rollers 12, so that two openings are reserved in a plurality of rollers 12 for installing the first supporting assembly 13 and the second supporting assembly 14; the first supporting assembly 13 corresponds to the position of the material turning member 31, and the second supporting assembly 14 corresponds to the position of the material receiving member 32. The first supporting assembly 13 and the second supporting assembly 14 correspond to the positions of the glass substrate 6 before and after flipping, respectively, and can support the glass substrate 6 before and after flipping.

[0036] In one embodiment, see Figures 3 to 5 The first supporting assembly 13 includes a first supporting frame 131, a first ball 132 and a first lifting cylinder 133. The first supporting frame 131 is arranged in the frame 11 and can slide up and down in the frame 11. The first supporting frame 131 corresponds to the position of the turning piece 31. The upper surface of the first supporting frame 131 is provided with a plurality of first balls 132 in an array. The first balls 132 are all rotatably connected to the first supporting frame 131. The driving end of the first lifting cylinder 133 is fixedly connected to the first supporting frame 131 to drive the first supporting frame 131 to rise and fall, so as to adjust the height of the plurality of first balls 132.

[0037] The second support assembly 14 includes a second support frame 141, a second ball 142 and a second lifting cylinder 143. The second support frame 141 is arranged in the frame 11 and can slide up and down in the frame 11. The second support frame 141 corresponds to the position of the material receiving member 32. The upper surface of the second support frame 141 is provided with a plurality of second balls 142 in an array. The plurality of second balls 142 are rotatably connected to the second support frame 141. The driving end of the second lifting cylinder 143 is fixedly connected to the second support frame 141 to drive the second support frame 141 to rise and fall, so as to adjust the height of the plurality of second balls 142.

[0038] During implementation, under normal working conditions, the heights of the first ball 132 and the second ball 142 are equal to the height of the roller 12, and can support the glass substrate 6 being transported. If the glass substrate 6 needs to be rotated to process the other side of the glass substrate 6, the lifting cylinder can be used to drive the ball to move upward to prop up the glass substrate 6. At this time, the glass substrate 6 is clamped between the ball and the connecting belt 453. The second motor drives the fixing assembly 45 to rotate, which can drive the glass substrate 6 on the ball to rotate, so as to perform multi-sided grinding of the glass substrate 6. This solution can realize multi-sided and double-sided grinding of the glass substrate 6, and can automatically change sides and turn over. The fixing assembly 45 can also repeat positioning after changing sides and turning over the glass substrate 6, thereby effectively improving the grinding work efficiency.

[0039] It should be noted that the supporting widths of the first supporting assembly 13 and the second supporting assembly 14 are both smaller than the width of the glass substrate 6, so that the first supporting assembly 13 and the second supporting assembly 14 can support the glass substrate 6 when they are raised, and after they are lowered, the glass substrate 6 can at least partially contact the roller 12, so as to be conveyed to the discharge end of the conveying mechanism 1 under the drive of the roller 12.

[0040] Furthermore, the first support assembly 13 also includes four first position-limiting telescopic rods 134, which are respectively arranged at the four corners of the bottom of the first support frame 131, and are respectively connected to the first support frame 131 and the frame 11, so as to achieve the guiding and limiting of the first support frame 131; the second support assembly 14 also includes four second position-limiting telescopic rods 144, which are respectively arranged at the four corners of the bottom of the second support frame 141, and are respectively connected to the second support frame 141 and the frame 11, so as to achieve the guiding and limiting of the second support frame 141.

[0041] Since the position of the glass substrate 6 is different before and after the flipping, the grinding mechanism 2 also needs to adjust the position accordingly so as to perform the grinding process on the flipped glass substrate 6; Figure 2 The grinding mechanism 2 also includes a mounting slide 25, a slide rail bracket 26, a connecting rod 27 and a positioning support plate 28. The slide rail bracket 26 is installed on the frame 11 and has a slide groove. One end of the mounting slide 25 is slidably arranged in the slide groove. The electric guide rail 23 is installed on the mounting slide 25. The mounting slide 25 is connected to the sleeve part of the third lifting cylinder through the connecting rod 27. The other end of the connecting rod 27 is slidably connected to the positioning support plate 28. The positioning support plate 28 is fixedly installed on the fixing frame 41, so that when the positioning driving member 42 drives the third lifting cylinder and the fixing assembly 45 to move, the grinding wheel 22 and the measuring member 24 can be driven to move left and right through the connecting rod 27, so that they can correspond to the position of the glass substrate 6 before and after flipping.

The installation box 51 is arranged at the lower part of the grinding mechanism 2 and fixed to one side of the top surface of the frame 11. Two adsorption slots 52 are respectively arranged at the positions corresponding to the front and back of the glass substrate 6 when it is turned over. A plurality of dust suction holes 53 connected to the adsorption slots 52 are opened on one side of the installation box 51, and a connecting hole 54 connected to the adsorption slots 52 is also provided to connect a dust suction fan through the connecting hole 54. At the same time, a collection box 55 is arranged in the adsorption slot 52, and a filter is arranged at the connecting hole 54. When implemented, the dust suction fan can be turned on to absorb the dust generated by grinding through the adsorption slots 52 and the dust suction holes 53, and the dust is filtered through the filter and retained in the collection box 55, which is convenient for cleaning.

[0043] The present invention provides a conveying mechanism 1, a grinding mechanism 2, a flipping mechanism 3 and a fixing mechanism 4. The conveying mechanism 1 realizes the feeding of the glass substrate 6. The grinding mechanism 2 is used to grind the edge of the glass substrate 6.
