Description

Technical Field

[0001] This utility model relates to the field of Low-E glass production and processing technology, and in particular to an edge grinding device for Low-E glass production. Background Technology

[0002] Low-E glass, also known as low-emissivity glass, is a product with multiple layers of metal or other compound coatings on its surface. Compared to traditional glass, it offers superior heat insulation and good light transmission. To eliminate micro-cracks and stress concentration at the glass edges, and to improve yield and safety, edge grinding is necessary during production. Existing low-E glass edge grinding equipment often uses a method of clamping and pressing the central area of ​​the glass before grinding the edges. During operation, the glass is manually or via a conveyor belt placed into the clamping area. If the glass is misaligned, subsequent clamping and grinding can result in uneven or misaligned edges, affecting both aesthetics and quality. Utility Model Content

Detailed Implementation

[0044] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0045] like Figure 1As shown, this embodiment discloses a grinding device for producing LOW-E glass, including a transfer table 1. The transfer table 1 is located at the end of a first conveyor line 6, which transports LOW-E glass onto the transfer table 1. The transfer table 1 is mounted on a moving mechanism 2, and a positioning device 3 is located above the transfer table 1 to position the glass. The transfer table 1 then temporarily fixes the glass. Grinding and clamping devices 4 are located on the left and right sides of the end of the moving mechanism 2 in the forward direction. A second conveyor line 7 is located on one side of the grinding and clamping devices 4, and a take-up mechanism 5 is located above the grinding and clamping devices 4. The moving mechanism 2 drives the transfer table 1 to transfer the glass between the grinding and clamping devices 4. The grinding and clamping devices 4 clamp and grind the glass. At this time, the transfer table 1 can be reset. After the grinding and clamping devices 4 have completed the grinding and clamping, the take-up mechanism 5 removes the glass and places it on the second conveyor line 7 for transport.

[0046] The transfer table 1 includes a platform 1-1. The first conveyor line 6 transports low-e glass onto the platform 1-1. The platform 1-1 is mounted on a movable frame 2. A temporary fixing device 1-2 is installed inside the platform 1-1. The temporary fixing device 1-2 includes a first electric suction cup 1-2-1. After activation, the first electric suction cup 1-2-1 can hold the glass in place, providing temporary fixation. The electric suction cup is existing technology and can be purchased online (such as the YSW-E / D / H brand from Yi San Wu), and will not be described in detail here.

[0047] The positioning device 3 includes two parallel rods 3-1. The two ends of the parallel rods 3-1 are provided with self-resetting positioning plates 3-2 that are slidably connected. The self-resetting positioning plates 3-2 are arranged in parallel on the left and right sides of the platform 1-1. A drive mechanism 3-3 is provided between the two parallel rods 3-1. The self-resetting positioning plates 3-2 are connected to the drive mechanism 3-3.

[0048] The clamping and grinding device 4 includes multiple C-shaped frames 4-1, with upper and lower clamping mechanisms 4-2 installed inside the C-shaped frames 4-1, and a grinding mechanism 4-3 that can move laterally installed inside the C-shaped frames 4-1.

[0049] In this embodiment, two parallel rods 3-1 are provided, and the two ends of the parallel rods 3-1 are fixedly connected to the ground by uprights 3-4.

[0050] like Figures 2 to 4As shown, the self-resetting positioning plate 3-2 includes a baffle 3-2-1, which is arranged parallel to the left and right sides of the platform 1-1. The baffle 3-2-1 is fixedly connected to the lower part of the U-shaped frame 3-2-2. The upper end of the U-shaped frame 3-2-2 is slidably connected to the left and right ends of the parallel rod 3-1. An annular plate 3-1-1 is fixedly connected to the parallel rod 3-1 between the U-shaped frame 3-2-2 and the drive mechanism 3-3. A spring 3-2-3 is provided between the annular plate 3-1-1 and the U-shaped frame 3-2-2, with one end of the spring 3-2-3 abutting against the annular plate 3-1-1 and the other end of the spring 3-2-3 abutting against the U-shaped frame 3-2-2. In this embodiment, the self-resetting positioning plate 3-2 also includes a limiting short ring edge 3-2-4, which is fixedly set on the parallel rod 3-1 and located at the outer position of the maximum stroke of the U-shaped frame 3-2-2, thus limiting the U-shaped frame 3-2-2.

[0051] The drive mechanism 3-3 includes a drive platform 3-3-1, which is fixedly arranged between parallel rods 3-1 and located in the middle of the two self-resetting positioning plates 3-2. A second motor 3-3-2 is fixedly arranged inside the drive platform 3-3-1. The output shaft of the second motor 3-3-2 can move through the drive platform 3-3-1 and is arranged on a rhomboid turntable 3-3-3. The output shaft of the second motor 3-3-2 is fixedly connected to the geometric center of the rhomboid turntable 3-3-3. First fixed shafts 3-3-4 are arranged at both ends of the long axis of the rhomboid turntable 3-3-3. The first fixed shafts 3-3-4 are rotatably connected to one end of the connecting rod 3-3-5, and the other end of the connecting rod 3-3-5 is rotatably connected to the second fixed shaft 3-3-6. The second fixed shaft 3-3-6 is fixedly arranged in the horizontal middle position of the cross plate of the U-shaped frame 3-2-2.

[0052] During operation, the first conveyor line 6 transports the low-e glass to platform 1-1, activating the second motor 3-3-2. The second motor 3-3-2 rotates counter-clockwise by a certain angle, causing the rhombus-shaped turntable 3-3-3 to rotate counter-clockwise by a certain angle. At this time, the rhombus-shaped turntable 3-3-3 pulls the connecting rods 3-3-5 on both sides. The connecting rods 3-3-5 pull the U-shaped frame 3-2-2 and the baffle 3-2-1 towards the center position. The spring 3-2-3 is compressed, and the baffle 3-2-1 moves towards the center. The glass on platform 1-1 is moved, contacted, and manipulated. Since the glass is in a movable state on platform 1-1, the baffle 3-2-1 positions the glass on platform 1-1, ensuring it is centered. Then, the first electric suction cup 1-2-1 is activated to hold the glass in place. Next, the second motor 3-3-2 is reversed, and under the elastic force of spring 3-2-3, the U-shaped frame 3-2-2 and the baffle 3-2-1 reset, causing the glass to detach from the baffle 3-2-1. It should be noted that the rotation angle of motor 3-3-2 needs to be set in advance to avoid excessive rotation of the diamond-shaped turntable 3-3-3, which could lead to excessive clamping by the baffle 3-2-1 and damage to the glass due to excessive pressure.

[0053] like Figures 5 to 6 As shown, the moving mechanism 2 includes a housing 2-1 and a base frame 2-2. The base frame 2-2 is equipped with a first slide rail 2-3 and a first screw 2-4 rotatably connected thereto. One end of the first screw 2-4 is connected to a first motor 2-5. A platform 1-1 is located at the top of the housing 2-1, and a first internally threaded sleeve 2-1-1 and a first sliding groove 2-1-2 are fixedly connected at the bottom of the housing 2-1. The first internally threaded sleeve 2-1-1 is threadedly connected to the first screw 2-4, and the first sliding groove 2-1-2 is slidably mounted on the first slide rail 2-3. When the first motor 2-5 is started, it rotates the first screw 2-4, allowing the housing 2-1 and platform 1-1 to move, thereby moving the platform 1-1 to a position between the two clamping and grinding devices 4.

[0054] like Figures 7 to 10 As shown, multiple C-shaped frames 4-1 are fixedly installed on the ground by the frame body, and the upper and lower arms of the C-shaped frames 4-1 face the extension line of the movable frame 2.

[0055] The upper and lower clamping mechanism 4-2 includes an upper fixed plate 4-2-1 and a lower fixed plate 4-2-4. The upper fixed plate 4-2-1 is fixedly connected to the upper arm end of the C-shaped frame 4-1. Multiple pressing cylinders 4-2-2 are provided on the lower surface of the upper fixed plate 4-2-1. The fixed end of the pressing cylinder 4-2-2 is fixedly connected to the lower surface of the upper fixed plate 4-2-1, and the telescopic end of the pressing cylinder 4-2-2 is fixedly connected to the upper clamping plate 4-2-3.

[0056] The lower fixing plate 4-2-4 is fixedly connected to the lower arm end of the C-shaped frame 4-1. Multiple upper lifting cylinders 4-2-5 are provided on the upper surface of the lower fixing plate 4-2-4. The fixed end of the upper lifting cylinder 4-2-5 is fixedly connected to the upper surface of the lower fixing plate 4-2-4, and the telescopic end of the upper lifting cylinder 4-2-5 is fixedly connected to the lower clamping plate 4-2-6.

[0057] After the platform 1-1 adheres to the glass, it moves to the space between the two clamping and grinding devices 4 on the left and right sides with the help of the moving mechanism 2. The glass is positioned between the upper clamping plate 4-2-3 and the lower clamping plate 4-2-6. The downward pressing cylinder 4-2-2 and the upward lifting cylinder 4-2-5 are activated, so that the upper clamping plate 4-2-3 and the lower clamping plate 4-2-6 clamp the side of the glass in an up-down manner. The upper clamping plate 4-2-3 and the lower clamping plate 4-2-6 leave a safe distance from the edge of the glass, so that the edge of the glass to be ground is exposed for grinding. At this time, the first electric suction cup 1-2-1 is turned off and no longer adheres to the glass. The first motor 2-5 is started to reverse and reset the platform 1-1 to start the positioning work of the next glass.

[0058] The edge grinding mechanism 4-3 includes a slide plate 4-3-1 and a motor housing 4-3-8. The slide plate 4-3-1 is fixedly connected to the support block 4-3-2. The vertical side wall of the support block 4-3-2 is fixedly connected to the telescopic end of the horizontal push cylinder 4-3-3. The fixed end of the horizontal push cylinder 4-3-3 is fixedly connected to the vertical side wall of the C-shaped frame 4-1. A second slide groove 4-3-4 is provided at the bottom of the slide plate 4-3-1. A second slide rail 4-3-5 is provided on the upper surface of the lower arm of the C-shaped frame 4-1. The second slide groove 4-3-4 is slidably connected to the second slide rail 4-3-5.

[0059] The slide plate 4-3-1 is provided with a rack 4-3-6 and a third slide rail 4-3-7 along its length. The bottom of the motor housing 4-3-8 is provided with a third slide groove 4-3-9, which is slidably connected to the third slide rail 4-3-7. A third motor 4-3-10 is fixedly installed inside the motor housing 4-3-8. A gear 4-3-11 is fixedly installed at the output end of the third motor 4-3-10. The gear 4-3-11 meshes with the rack 4-3-6. A fourth motor 4-3-12 is fixedly installed on the top outer side of the motor housing 4-3-8. A grinding wheel 4-3-13 is provided at the output end of the fourth motor 4-3-12. In this embodiment, the third slide rail 4-3-7 is an I-shaped slide rail, the two vertical walls of the third slide rail 4-3-7 are sliding contact surfaces, and the third slide groove 4-3-9 is placed on both sides of the third slide rail 4-3-7 and slides in contact with the two vertical walls of the third slide rail 4-3-7.

[0060] In this embodiment, the rack 4-3-6 is mounted on the I-shaped slide rail (the two vertical walls of the I-shaped slide rail are sliding contact surfaces), and the bottom edge of the motor housing 4-3-8 is mounted on the side wall slide rail of the I-shaped slide rail and slides in contact with the side wall slide rail of the I-shaped slide rail.

[0061] like Figure 11 As shown, firstly, the horizontal thrust cylinder 4-3-3 extends, causing the grinding wheel 4-3-13 to adhere to the glass edge clamped by the upper clamping plate 4-2-3 and the lower clamping plate 4-2-6. Then, the fourth motor 4-3-12 is started to drive the grinding wheel 4-3-13 to rotate for grinding. The third motor 4-3-10 is started, driving the gear 4-3-11 to rotate. With the meshing of the gear 4-3-11 and the rack 4-3-6 and the limiting of the third slide groove 4-3-9, the motor box 4-3-8 can move linearly on the slide plate 4-3-1, thereby driving the fourth motor 4-3-12 and the grinding wheel 4-3-13 to move linearly along the glass edge to complete the grinding of the entire glass edge. It should be noted that in this embodiment, the height of platform 1-1, the middle position of upper clamping plate 4-2-3 and lower clamping plate 4-2-6, and the height of grinding wheel 4-3-13 need to be set and coordinated in advance to avoid errors in the height of the grinding position.

[0062] like Figure 12 As shown, the retrieval mechanism 5 includes a support frame 5-1 and a retrieval arm 5-5. The support frame 5-1 is horizontally positioned above the clamping and grinding device 4. The retrieval arm 5-5 is located above the glass clamped by the upper clamping plate 4-2-3 and the lower clamping plate 4-2-6. The support frame 5-1 is provided with a guide rod 5-2 and a rotatable second screw 5-3. One end of the second screw 5-3 is fixedly connected to the output end of the fifth motor 5-4.

[0063] The pick-and-place arm 5-5 includes a horizontal arm 5-5-1. A second internally threaded sleeve 5-5-2 and a sliding sleeve 5-5-3 are fixedly installed inside the horizontal arm 5-5-1. The second internally threaded sleeve 5-5-2 is threaded onto the second screw 5-3, and the sliding sleeve 5-5-3 is slidably fitted onto the guide rod 5-2. One end of the horizontal arm 5-5-1 is equipped with a downward-facing pick-and-place cylinder 5-5-4. A second electric suction cup 5-5-5 is installed at the telescopic end of the pick-and-place cylinder 5-5-4.

[0064] Initially, the second electric suction cup 5-5-5 is positioned above the glass held by the upper clamping plate 4-2-3 and the lower clamping plate 4-2-6. After the polishing is completed, the third motor 4-3-10 and the fourth motor 4-3-12 stop. The telescopic end of the take-up cylinder 5-5-4 extends, causing the second electric suction cup 5-5-5 to adhere to and hold the glass. Then, the horizontal push cylinder 4-3-3 resets, causing the polishing wheel 4-3-13 to leave the glass. Finally, the downward pressure... Cylinders 4-2-2 and 4-2-5 are reset, and the upper clamping plate 4-2-3 and lower clamping plate 4-2-6 are reset and no longer clamp the glass. At this time, only the second electric suction cup 5-5-5 holds the glass. Then, the fifth motor 5-4 is started to drive the second screw 5-3 to rotate, so that the horizontal arm 5-5-1 and the pick-and-place cylinder 5-5-4 move the glass to the second conveyor line 7. Then, the second electric suction cup 5-5-5 is turned off and the glass is placed on the second conveyor line 7 and transported away.

[0065] The working process of this utility model is as follows:

[0066] The first step, glass positioning and transfer, begins with the first conveyor line 6 transporting the low-e glass to platform 1-1. The second motor 3-3-2 starts and rotates counter-clockwise at a certain angle, causing the diamond-shaped turntable 3-3-3 to rotate counter-clockwise. This pulls the connecting rods 3-3-5 on both sides, which in turn pull the U-shaped frame 3-2-2 and the baffle 3-2-1 towards the center. At this time, the spring 3-2-3 is compressed, and the baffle 3-2-1 moves towards the center, contacting and moving the glass on platform 1-1, thus aligning the glass in the center. Then, the first electric suction cup 1-2-1 is activated and holds the glass. The second motor 3-3-2 is then reversed, and under the elastic force of the spring 3-2-3, the U-shaped frame 3-2-2 and the baffle 3-2-1 reset, allowing the glass to detach from the baffle 3-2-1. Finally, the first motor 2-5 starts, driving the first screw 2-4 to rotate, thus moving the housing 2-1 and platform 1-1 to the position between the two clamping and edge-grinding devices 4. At this point, the glass adsorbed on platform 1-1 is moved to the middle position between the upper clamping plate 4-2-3 and the lower clamping plate 4-2-6.

[0067] The second step is the clamping and edge grinding of the glass. After the glass is positioned between the upper clamping plate 4-2-3 and the lower clamping plate 4-2-6, the downward pressing cylinder 4-2-2 and the upward lifting cylinder 4-2-5 are activated, causing the upper clamping plate 4-2-3 and the lower clamping plate 4-2-6 to clamp the side of the glass in an up-down manner. The upper clamping plate 4-2-3 and the lower clamping plate 4-2-6 are left with a safe distance from the edge of the glass, so that the edge of the glass to be ground is exposed for the edge grinding work. At this time, the first electric suction cup 1-2-1 is turned off and no longer adsorbs the glass. The first motor 2-5 is started and reversed to reset the platform 1-1, and the positioning work of the next glass is carried out. Then, the horizontal thrust cylinder 4-3-3 extends, causing the grinding wheel 4-3-13 to adhere to the glass edge clamped by the upper clamping plate 4-2-3 and the lower clamping plate 4-2-6. Then, the fourth motor 4-3-12 is started to drive the grinding wheel 4-3-13 to rotate for grinding. The third motor 4-3-10 is started, driving the gear 4-3-11 to rotate. With the meshing of the gear 4-3-11 and the rack 4-3-6 and the limiting of the third slide groove 4-3-9, the motor box 4-3-8 can move linearly on the slide plate 4-3-1, thereby driving the fourth motor 4-3-12 and the grinding wheel 4-3-13 to move linearly along the glass edge to complete the grinding of the entire glass edge.

[0068] The third step is to remove the glass after edge grinding. After the glass edge grinding is completed, the third motor 4-3-10 and the fourth motor 4-3-12 are turned off. The telescopic end of the pick-and-place cylinder 5-5-4 extends, allowing the second electric suction cup 5-5-5 to adhere to and hold the glass. Then, the horizontal push cylinder 4-3-3 resets, causing the grinding wheel 4-3-13 to leave the glass. Next, the downward press cylinder 4-2-2 and the upward push cylinder 4-2-5 reset, and the upper clamping plate 4-2-3 and the lower clamping plate 4-2-6 reset and no longer hold the glass. At this time, only the second electric suction cup 5-5-5 holds the glass. Then, the fifth motor 5-4 is started to drive the second screw 5-3 to rotate, causing the horizontal arm 5-5-1 and the pick-and-place cylinder 5-5-4 to move the glass to the second conveyor line 7. Finally, the second electric suction cup 5-5-5 is turned off, and the glass is placed on the second conveyor line 7 and transported away.
