[0002] A glass tempering furnace is usually also called a glass tempering device, a glass tempering unit, a tempering furnace, etc. A glass tempering furnace uses physical or chemical methods to form a compressive stress layer on the glass surface and a tensile stress layer inside. When the glass is subjected to an external force, the compressive stress layer can offset part of the tensile stress to avoid glass breakage, thereby achieving the purpose of improving the strength of the glass.

[0003] Refractory and heat-insulating thermal insulation cotton is an important heat-insulating component of the tempering furnace. However, because its material can cause harm to the human skin and eyes, during installation, personnel need to wear protective equipment. However, wearing protective equipment will cause inconvenience in work and low installation efficiency. In addition, since the thermal insulation structure is assembled with modular cotton and the number of modular cotton is large, it also results in low overall installation efficiency.

Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more, unless otherwise clearly and specifically limited.

[0037] Refer to Figure 1 and Figure 2 This embodiment discloses a filling cotton system for a flat glass tempering furnace, including a heat-insulating cotton feeding mechanism 1, a nut feeding mechanism 2, a traveling mechanism 3, a flipping mechanism 4, a grasping mechanism 5, and a tightening mechanism 6. The output end of the traveling mechanism 3 is connected to the grasping mechanism 5 through the flipping mechanism 4. The tightening mechanism 6 is arranged on the grasping mechanism 5. A heat-insulating cotton feeding mechanism 1 and a nut feeding mechanism 2 are arranged on one side close to the traveling mechanism 3, and a workbench is arranged below the traveling mechanism 3.

[0038] Refer to Figure 3 and Figure 4, the thermal insulation cotton feeding mechanism 1 includes a conveyor belt assembly 11, a material blocking assembly 12 and a material pushing assembly 13. The conveyor belt assembly 11 is composed of a conveyor support and a belt conveying structure. The thermal insulation cotton 7 is placed on the conveyor belt of the belt conveying structure for conveying. Four groups of material blocking assemblies 12 are arranged in parallel at one end of the conveyor belt assembly 11 close to the walking mechanism 3, and a material pushing assembly 13 is arranged on the side opposite to the material blocking end of the material blocking assembly 12.

[0039] The material blocking assembly 12 includes a material blocking cylinder 121 and a material blocking bar 122. The material blocking cylinder 121 is fixed on the conveyor support, and the output end of the material blocking cylinder 121 is arranged towards the conveyor belt of the belt conveying structure and connected to the material blocking bar 122.

[0040] The material pushing assembly 13 includes a material pushing cylinder 131 and a material pushing plate 132. The material pushing cylinder 131 is fixed on the conveyor support, and the output end of the material pushing cylinder 131 is arranged towards the conveyor belt of the belt conveying structure and connected to the material pushing plate 132, so that the material retreating plate 132 can move towards the material blocking bar 122.

[0041] Further, a sensor is also provided on the belt conveying structure.

[0042] Specifically, the thermal insulation cotton 7 is manually placed face up on the conveyor belt. When the first piece of thermal insulation cotton 7 passes through the sensor, the first material blocking cylinder 121 close to the walking mechanism 3 acts, extends the material blocking bar 122, and positions the first piece of thermal insulation cotton 7. And so on. When the last piece of thermal insulation cotton 7 passes through the sensor, the last material blocking cylinder 121 close to the sensor acts, extends the material blocking bar 122, and positions the last piece of thermal insulation cotton 7. At this time, the action of the material blocking assembly 12 is completed, and the material pushing cylinder 131 starts to act, pushes the material pushing plate 132, and pushes the thermal insulation cotton 7 positioned on the side of the material blocking bar 122 flat to the side of the conveyor belt for positioning. Then the material pushing cylinder 131 retracts and waits for the gripping mechanism 5 to grip.

[0043] Refer to Figure 5 and Figure 6, the nut feeding mechanism 2 includes a feeding base 21, a pushing cylinder 22, a pushing rod 23, a pushing block 24 and a storage bin 25. The pushing cylinder 22 is fixed on the feeding base 21. In this embodiment, the pushing cylinder 22 is a double-rod cylinder. The output end of the pushing cylinder 22 is connected to the pushing rod 23 that can slide on the feeding base 21. Four groups of pushing blocks 24 are arranged on the pushing rod 23. A receiving step 241 is arranged at the end of the pushing block 24 away from the pushing rod 23 for receiving nuts. Above each group of pushing blocks 24, there is a storage bin 25 that penetrates up and down for storing nuts. The bottom of the storage bin 25 is attached to the top surface of the pushing block 24. An opening 251 is arranged at the bottom of the storage bin 25 in the nut conveying direction. The distance between the bottom surface of the receiving step 241 and the top surface of the opening 251 at the bottom of the storage bin 25 is greater than the thickness of one nut and less than the thickness of two nuts, ensuring that only one nut can be taken away when the receiving step 241 moves, and the other nut is attached to the top surface of the pushing block 24.

[0044] In this embodiment, the nut is a hexagonal nut. The height difference of the receiving step 241 is about 1 / 2 of the nut thickness. The side wall of the receiving step 241 is provided with an inward concave shape matching the nut. The pushing block 23 also has weak magnetism to prevent the nut from rotating during the pushing process.

[0045] The bottom of the pushing rod 23 is slidably arranged on the feeding base 21 through a feeding sliding component 26. The feeding sliding component 26 includes a linear bearing 261 and a guide rod 262. Two groups of linear bearings 261 are respectively arranged on the feeding base 21 on both sides of the pushing cylinder 22 along the conveying direction of the pushing cylinder 22. A guide rod 262 is arranged on each group of linear bearings 261. The bottom of the pushing rod 23 is slidably sleeved on the guide rod 262 through a slider. The pushing cylinder 22 is driven to drive the pushing rod 23 to slide on the guide rod 262.

[0046] Further, a feeding bottom plate 27 is also arranged on the feeding base 21. Guide grooves 271 corresponding to the number and positions of the pushing blocks 24 are opened on the feeding bottom plate 27, causing the pushing blocks 24 to slide in the guide grooves 271 to play a role in feeding guidance.

[0047] Furthermore, the bottom surface height of the pushing block 24 is higher than the top surface height of the heat insulation cotton 7 on the conveyor belt assembly 11, ensuring that the pushing block 24 can push the nut to directly above the central hole of the heat insulation cotton 7.

[0048] Specifically, when feeding is required, the pushing cylinder 22 acts to drive the pushing rod 23 to push the pushing block 24 forward, pushing out the lowest group of nuts in the storage bin 25 and adsorbing them on the receiving step 241 of the pushing block 24. When the cylinder reaches the limit position, the nut is fed to directly above the central hole of the heat insulation cotton 7 and waits to be grabbed by the tightening mechanism 6.

[0049] Refer again to Figure 1 and Figure 2 The traveling mechanism 3 includes a support frame 31, an X-axis drive assembly 32, a Y-axis drive assembly 33, a Z-axis drive assembly 34, and a rotation assembly 35. The support frame 31 is a truss structure. The workbench is arranged below the support frame 31. The X-axis drive assembly 32 is arranged on the support frame 31. The output end of the X-axis drive assembly 32 is connected to the Y-axis drive assembly 33. The output end of the Y-axis drive assembly 33 is connected to the Z-axis drive assembly 34. The output end of the Z-axis drive assembly 34 is connected to the flipping mechanism 4 through the rotation assembly 35. Specifically, the rotation assembly 35 drives the flipping mechanism 4 to rotate. The Z-axis drive assembly 34 drives the rotation assembly 35 to move in the Z-axis direction on the support frame 31. The Y-axis drive assembly 33 drives the Z-axis drive assembly 34 to move in the Y-axis direction on the support frame 31. The X-axis drive assembly 32 drives the Y-axis drive assembly 33 to move in the X-axis direction on the support frame 31, enabling the flipping mechanism 4 to achieve omnidirectional movement. Furthermore, the grasping mechanism 5 and the tightening mechanism 6 follow the flipping mechanism 4 to achieve omnidirectional movement.

[0050] The X-axis drive assembly 32, the Y-axis drive assembly 33, and the Z-axis drive assembly 34 are all rack drive structures, including a motor, a gear, and a rack. The output end of the motor is connected to the gear meshing with the rack. The rack is arranged on the support frame 31 along the X-axis, Y-axis, and Z-axis directions respectively. The driving of the motors in the X-axis, Y-axis, and Z-axis directions drives the flipping mechanism 4 to move in each axis direction.

[0051] The rotation assembly 35 is a rotary motor that can be purchased in the market, and its output end is connected to the flipping mechanism 4.

[0052] Refer to Figure 7 and Figure 8 The flipping mechanism 4 includes a fixing plate 41 and a flipping drive assembly 42. One end of the fixing plate 41 is connected to the output end of the rotation assembly 35, and the other end is connected to the grasping mechanism 5 through the flipping drive assembly 42. By driving the flipping drive assembly 42, the flipping of the grasping mechanism 5 is realized, thereby driving the tightening mechanism 6 to flip, and further driving the flipping of the heat preservation cotton 7 grasped by the grasping mechanism 5 to meet the installation requirements of the heat preservation cotton 7.

[0053] Specifically, the flipping drive assembly 42 includes a flipping cylinder 421, a guide rail 422, a flipping rack 423, a bracket 424, a central shaft 425, a flipping gear 426, and a connecting rod 427. The flipping cylinder 421 and the guide rail 422 are both fixed on the fixing plate 41. A flipping rack 423 capable of sliding on the guide rail 422 is provided on the output end of the flipping cylinder 421. The fixing plate 41 is fixed with a bracket 424, and a rotatable central shaft 425 is provided on the bracket 424. A flipping gear 426 and a connecting rod 427 are fixed on the central shaft 425. The other end of the connecting rod 427 is connected to the grasping mechanism 5, and the flipping gear 426 meshes with the flipping rack 423. Specifically, by driving the flipping cylinder 421, the flipping rack 423 is driven to move on the guide rail 422, thereby driving the flipping gear 426 to rotate, and further driving the grasping mechanism 5 to rotate through the central shaft 425.

[0054] Further, the flipping mechanism 4 further includes a limiting column 43. The limiting column 43 is fixed on the fixing plate 41 to limit the flipping angle of the grasping mechanism 5. In this embodiment, the grasping mechanism 5 is flipped to 90° and abuts against the limiting column 43, and at this time, the operation of the flipping cylinder 421 is stopped.

[0055] Refer to Figures 9 to 11 , the grasping mechanism 5 includes a grasping cylinder 51, a clamping plate frame 52, clamping plates 53, and a support plate 54. Two groups of grasping cylinders 51 are fixedly arranged in parallel on the support plate 54 and their telescopic ends are arranged in opposite directions. In this embodiment, the grasping cylinder is fixed on the support plate 54 through a connecting frame; the output end of each group of grasping cylinders 51 is connected to a clamping plate frame 52 capable of moving on the support plate 54. Four clamping plates 53 are arranged side by side on each clamping plate frame 52. The clamping plates 53 on the two clamping plate frames 52 are provided with mutually staggered tooth grooves 531 so that the two clamping plates 53 can penetrate through each other. Specifically, when the grasping cylinder 51 acts, the clamping plates 53 at adjacent stations on the two clamping plate frames 52 approach each other to play a clamping role, realizing the clamping of the thermal insulation cotton 7 on the conveyor belt assembly 11. By providing mutually staggered tooth grooves 531 on the clamping plates 53, the linear movement space between the two clamping plate frames 52 is reduced, thereby reducing the occupied space of the grasping mechanism 5.

[0056] The support plate 54 is connected to the connecting rod 427 in a T shape. Refer to Figure 12 , an installation through hole 541 is formed on the support plate 54, the tightening mechanism 6 is fixed in the installation through hole 541, and the tightening end of the tightening mechanism 6 is perpendicular to the support plate 54.

[0057] Further, the bottom of the clamping plate holder 52 is slidably arranged on the support plate 54 through a grasping sliding assembly 55. The grasping sliding assembly 55 includes a grasping sliding seat 551 and a grasping sliding rail 552. A set of grasping sliding seats 551 are fixed on the support plate 54 along the length direction of the clamping plate holder 52, and a grasping sliding rail 552 slidably matched with the grasping sliding seats 551 is fixed at the bottom of the clamping plate holder 52.

[0058] Further, the output end of the grasping cylinder 51 is connected to the side surface of the clamping plate holder 52 through a connecting block 56.

[0059] Still further, a limiting block 58 is also fixed on the support plate 54 along the output direction of the grasping cylinder 51. When the connecting block 56 touches the limiting block 58, the grasping cylinder 51 stops expanding.

[0060] Further, a synchronous driving structure 57 is arranged between the two clamping plate holders 52. The synchronous driving structure 57 includes a synchronous rack 571 and a synchronous gear 572. Synchronous racks 571 are arranged on the opposite side surfaces of the two clamping plate holders 52 along their length directions, and a synchronous gear 572 that can rotate and meshes with the two synchronous racks 571 is arranged on the support plate 54, ensuring that the grasping cylinder 51 drives the two clamping plate holders 52 to move synchronously and the force is evenly distributed.

[0061] Refer to Figure 13 and Figure 14 , the tightening mechanism 6 includes a tightening base 61, a tightening driving assembly 62, a connecting plate 63, a sleeve 64, a sleeve rod 65, a spring 66, and a pneumatic screwdriver 67. The tightening base 61 is fixed on the installation through hole 541 of the support plate 54. The output end of the tightening driving assembly 62 fixed on the tightening base 61 is connected to the slidable connecting plate 63. Four sleeves 64 are arranged side by side on the connecting plate 63. The length direction of the sleeves 64 is perpendicular to the support plate 54. A sleeve rod 65 is sleeved on the sleeve 64. A spring 66 is arranged between the bottom of the inner cavity of the sleeve 64 and the sleeve rod 65. A pneumatic screwdriver 67 is sleeved on the sleeve rod 65 extending into the sleeve 64. A head 651 for clamping a hexagonal nut is arranged at the end of the sleeve rod 65 extending out of the sleeve 64. The head 651 has magnetism and can adsorb the hexagonal nut in the head 651.

[0062] The tightening drive assembly 62 includes a tightening cylinder 621, a tightening slide rail 622, and a tightening slider 623. The tightening cylinder 621 is fixed on the tightening base 61. Two groups of parallel tightening slide rails 622 are fixed along the length direction of the tightening base 61. A slidable tightening slider 623 is arranged on each group of tightening slide rails 622. The connecting plate 63 is fixed on the tightening slider 623. The output end of the tightening cylinder 621 is connected to the connecting plate 63. Specifically, by driving the tightening cylinder 621, the connecting plate 63 is driven to move on the tightening slide rail 622, and then the sleeve 64 on the connecting plate 63 is driven to move.

[0063] Further, an air inlet hole is provided on the sleeve 64. The air inlet pipe connected to the pneumatic screwdriver 67 is connected to an external pneumatic device through the air inlet hole to provide power for the pneumatic screwdriver 67.

[0064] Still further, a limiting member 68 is also provided on the tightening base 61. When the tightening cylinder 621 retracts, it drives the connecting plate 63 to retract. When the connecting plate 63 touches the limiting member 68, the operation of the tightening cylinder 621 stops.

[0065] Specifically, when the tightening mechanism 6 moves to the positioning position of the heat-insulating cotton 7 on the conveyor belt assembly 11, the tightening drive assembly 62 is driven to drive the connecting plate 63 to move downward, so as to drive the sleeve rod 65 to move downward through the sleeve 64. Relying on the pre-pressure of the spring 66, the end 651 of the sleeve rod 65 is aligned with and gently presses the nut on the blanking step 241. The magnetic nut on the end 651 of the sleeve rod 65 is adsorbed on the end 651. After the nut loading action is completed, the pusher cylinder 22 acts to drive the pusher block 24 to retract to the initial position for the next group of nuts to be loaded. Then, when the walking mechanism 3 drives the flipping mechanism 4 to move to the installation position of the heat-insulating cotton 7, the fixing screw on the toughening furnace penetrates the central hole on the heat-insulating cotton 7. At the same time, the tightening drive assembly 62 is driven to drive the connecting plate 63 to move downward, so as to drive the sleeve rod 65 to move downward through the sleeve 64, so that the nut on the end 651 is docked with the fixing screw. Finally, an external pneumatic device is driven, and the sleeve rod 65 is driven to rotate on the sleeve 64 through the pneumatic screwdriver 67, so as to drive the nut to rotate, and then the nut is threadedly connected to the fixing screw, and finally the heat-insulating cotton 7 is fixed on the toughening furnace.

[0066] It should be noted that the installation through hole 541 of the support plate 54 is arranged between the two groups of clamping plate frames 52, so that the sleeve rod 65 on the tightening mechanism 6 is located between the clamping plates 53 of adjacent workstations, and thus the tightening mechanism 6 does not affect the clamping plates 53 from grasping the heat-insulating cotton 7.

[0067] The working principle of this embodiment is as follows: First, manually place the front side of the thermal insulation cotton 7 on the conveyor belt. When the first piece of thermal insulation cotton 7 passes through the sensor, the first material blocking cylinder 121 near the walking mechanism 3 acts, extending the material blocking bar 122 to position the first piece of thermal insulation cotton 7. And so on. When the last piece of thermal insulation cotton 7 passes through the sensor, the last material blocking cylinder 121 near the sensor acts, extending the material blocking bar 122 to position the last piece of thermal insulation cotton 7. At this time, the material blocking assembly 12 has completed its action, and the material pushing cylinder 131 starts to act, pushing the material pushing plate 132 to push the thermal insulation cotton 7 positioned on the side of the material blocking bar 122 flat to the side of the conveyor belt for positioning. Then the material pushing cylinder 131 retracts and waits for the grasping mechanism 5 to grasp it.

[0068] Then drive the material pushing cylinder 22 to act, driving the material pushing rod 23 to push the material pushing block 24 forward. A set of bolts at the bottom of the storage bin 25 fall onto the receiving step 241. The material pushing block 24 advances to push out the nut adsorbed on the receiving step 241. When the material pushing cylinder 22 reaches the limit position, the nut is fed to directly above the central hole of the thermal insulation cotton 7 and waits for the tightening mechanism 6 to grasp it.

[0069] Then drive the rotating assembly 35 to drive the flipping mechanism 4 to rotate. Drive the rotating assembly 35 to move in the Z-axis direction on the support frame 31 through the Z-axis drive assembly 34. Drive the Z-axis drive assembly 34 to move in the Y-axis direction on the support frame 31 through the Y-axis drive assembly 33. Drive the Y-axis drive assembly 33 to move in the reverse X-axis direction on the support frame 31 through the X-axis drive assembly 32, so that the flipping mechanism 4 moves above the thermal insulation cotton 7, and further makes the grasping mechanism 5 and the tightening mechanism 6 on the flipping mechanism 4 located above the thermal insulation cotton 7.

[0070] Then drive the tightening drive assembly 62 to drive the connecting plate 63 to move downward, thereby driving the sleeve rod 65 to move downward through the sleeve 64. Relying on the pre-pressure of the spring 66, the end 651 of the sleeve rod 65 aligns with and gently presses the nut on the receiving step 241. The magnetic nut is adsorbed on the end 651 by relying on the end 651 of the sleeve rod 65. After the nut feeding action is completed, the material pushing cylinder 22 acts to drive the material pushing block 24 to retract to the initial position for the next set of nut feeding.

[0071] Then, the Z-axis drive assembly 34 drives the flipping mechanism 4 to move downward, so that the end 651 of the adsorption nut extends into the central hole of the thermal insulation cotton 7. At the same time, the grasping mechanism 5 also moves downward to drive the grasping cylinder 51 to act. The clamping plates 53 at adjacent stations on the two clamping plate frames 52 approach each other to clamp the thermal insulation cotton 7 between the material blocking assemblies 12. Then, the traveling mechanism 3 is driven to transport the grasped thermal insulation cotton 7 to the workbench below the support frame 31. According to the installation position, when the thermal insulation cotton 7 is installed on the side of the toughening furnace, by driving the flipping drive assembly 42, the support plate 43 is flipped by 90°, thereby driving the grasping mechanism 5 and the tightening mechanism 6 to flip, and further driving the flipping of the thermal insulation cotton 7 grasped by the grasping mechanism 5. And the rotation assembly 35 is driven to make the position of the thermal insulation cotton 7 meet the installation requirements. Then, the X-axis drive assembly 32 is driven to attach the thermal insulation cotton 7 to the toughening furnace, and the fixing screw on the toughening furnace penetrates through the central hole of the thermal insulation cotton 7. At the same time, the tightening drive assembly 62 is driven to drive the connecting plate 63 to move downward, so that the sleeve rod 65 is driven to move downward through the sleeve 64, and the nut on the end 651 is docked with the fixing screw. Finally, an external pneumatic device is driven, and the sleeve rod 65 is driven to rotate on the sleeve 64 through the pneumatic screwdriver 67, thereby driving the nut to rotate, and then the nut is threadedly connected to the fixing screw, and finally the thermal insulation cotton 7 is fixed on the side of the toughening furnace; when the thermal insulation cotton 7 is installed directly below the toughening furnace, the flipping drive assembly 42 is not driven, and the actions of the above-mentioned grasping mechanism 5 and tightening mechanism 6 are directly repeated to fix the thermal insulation cotton 7 directly below the toughening furnace.
