Description

Technical Field

[0001] This utility model relates to the field of ceramic firing, and in particular to a device for transferring blanks. Background Technology

[0002] Ceramic firing is a process in which ceramic blanks undergo high-temperature treatment, resulting in physical and chemical changes to produce ceramic products. In this process, the blank transfer device plays an indispensable role. It can not only quickly and accurately transfer the blanks, greatly improving production efficiency and meeting the needs of large-scale production, but also handle them smoothly, avoiding damage to the blanks due to external forces and ensuring product quality. At the same time, the blank transfer device reduces the workload of workers, reduces the harm to workers' health caused by dust, and improves the working environment. Furthermore, it is easy to connect with other equipment, promoting the automation and continuous operation of ceramic production, reducing costs, and enhancing the competitiveness of enterprises.

[0003] The robotic arm-type blank transfer device consists of three core parts: a robotic arm, an end effector, and a control system. The robotic arm, with its multiple degrees of freedom, rotates and moves its joints under the drive of motors and reducers, allowing for flexible positioning in three-dimensional space and providing basic mobility for handling blanks. The end effector is customized according to the actual characteristics of the blank; common types include suction cup and gripper types. The suction cup type uses a vacuum pump to extract air from the suction cup and uses negative pressure to adsorb the blank, while the gripper type relies on a motor or cylinder to drive the gripper to open and close, clamping the blank to complete the transfer. The control system acts as the "brain" of the device, precisely coordinating the movements of the robotic arm's joints and the end effector according to preset programs and instructions, regulating the robotic arm's trajectory and speed to ensure accurate blank grasping, handling, and placement, meeting the diverse blank transfer needs of ceramic production.

[0004] In the ceramic production process, the transfer device plays an indispensable role. However, it has revealed significant defects in practical applications. During equipment operation, the stability of the rotating block of the transfer device is poor, and it is prone to swaying from side to side. Once the rotating block sways, the supporting components connected to it will also shift, making it impossible for the ceramic blank to accurately reach the designated position during the handling process. This positional deviation problem not only requires workers to spend extra time to make secondary adjustments to the blank position, which seriously slows down the production rhythm, but may also cause uneven heating during firing due to improper blank position, which greatly increases the number of defective products and greatly affects the operating efficiency of the transfer device and the quality of ceramic production. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a blank-moving device, which aims to improve the problem that the rotating block is prone to swaying left and right during the use of the equipment, causing the ceramic blank to deviate in its position.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a blank transfer device, comprising a support plate, a gearbox fixedly connected to one side of the support plate, a motor fixedly connected to the top of the gearbox, the output end of the motor being connected to the inside of the gearbox, a plurality of support frames fixedly connected to the top of the support plate, a rotating shaft rotatably connected between the support frames, a plurality of connecting plates fixedly connected to the outer wall of the rotating shaft, a connecting column rotatably connected between the connecting plates, a rotating component provided on one side of one of the connecting plates, a plurality of fixing grooves provided on the outer wall of the connecting column, a plurality of rotating blocks slidably connected to the outer wall of the connecting column, and a plurality of limiting components provided inside each rotating block;

[0007] Each of the limiting components includes a fixed ring and multiple springs. The outer wall of each fixed ring is slidably connected to the inside of the rotating block. Each spring is disposed inside the rotating block. One end of each spring is fixedly connected to the inside of the rotating block, and the other end of each spring is fixedly connected to one side of the fixed ring.

[0008] As a further description of the above technical solution:

[0009] The rotating assembly includes a driving gear, a chain, and a driven gear. The inner wall of the driving gear is rotatably connected to one end of the rotating shaft. The chain is disposed on the outer walls of the driving gear and the driven gear. The inner wall of the driven gear is fixedly connected to one end of the connecting column. The outer walls of both the driving gear and the driven gear mesh with the chain.

[0010] As a further description of the above technical solution:

[0011] Each of the rotating blocks has a fixed plate fixedly connected to its bottom, and each fixed plate has multiple fixed tubes fixedly connected inside it.

[0012] As a further description of the above technical solution:

[0013] Each of the fixed tubes has an air inlet fixedly connected to its top, and each of the fixed tubes has multiple connecting slots at its bottom.

[0014] As a further description of the above technical solution:

[0015] Each of the fixed tubes is fixedly connected to an air guide tube inside, and each of the air guide tubes is fixedly connected to a sealing ring on its outer wall.

[0016] As a further description of the above technical solution:

[0017] Each of the fixed tubes is slidably connected to a suction cup at its bottom, and each of the suction cups is fixedly connected to a plurality of connecting strips at its top, with a limit strip fixedly connected to the top of each connecting strip.

[0021] Each of the connecting strips is provided with a second spring inside, one end of each second spring is fixedly connected to the inside of the connecting strip, and the other end of each second spring is fixedly connected to the bottom end of the fixing pin.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the two rotating blocks are first held and moved to the left or right, so that the inner fixing ring is squeezed into the interior of the rotating block by the outer wall of the connecting column. When the rotating block is moved to the position to be used, the rotating block is stopped, so that the inner fixing ring is popped out and slid into the fixing groove under the action of the spring. This achieves the effect of restricting the left and right movement of the rotating block during the use of the equipment, so that the ceramic blank always moves in one position. This avoids the problem that the rotating block is easy to shake left and right during the use of the equipment, causing the ceramic blank to deviate in position, thereby improving the efficiency of the blank transfer device.

[0024] 2. In this utility model, first hold the suction cup and rotate it clockwise so that the limiting strip comes out from the deepest part of the connecting groove. At the same time, the fixing pin is squeezed by the inner wall of the fixing tube and retracts into the limiting strip, thus pushing the suction cup out a short distance. Then, hold the suction cup and move it downward to remove the suction cup from the outer wall of the air guide tube. This achieves the effect of easily removing and replacing the suction cup during the use of the equipment, avoiding the problem of needing to use different equipment to move ceramic blanks of different sizes during the use of the equipment, thereby improving the practicality of the blank moving device.

[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0033] Reference Figures 1-3 An embodiment of this utility model provides a blank transfer device, including a support plate 1. A gearbox 2 is fixedly connected to one side of the support plate 1 for driving a rotating shaft 5 and a drive sprocket 8. A motor 3 is fixedly connected to the top of the gearbox 2 for driving the rotating shaft 5 and the drive sprocket 8. The output end of the motor 3 is connected to the inside of the gearbox 2. Multiple support frames 4 are fixedly connected to the top of the support plate 1 for supporting the rotating shaft 5. The rotating shaft 5 is rotatably connected between the support frames 4 for driving a connecting plate 6 to rotate. Multiple connecting plates 6 are fixedly connected to the outer wall of the rotating shaft 5 for fixing connecting columns 7. Connecting columns 7 are rotatably connected between the connecting plates 6 for connecting rotating blocks 12. A rotating component is provided on one side of one of the connecting plates 6 for driving the connecting column 7 to rotate. Multiple fixing grooves 11 are provided on the outer wall of the connecting column 7 for accommodating fixing rings 13. Multiple rotating blocks 12 are slidably connected to the outer wall of the connecting column 7 for connecting fixing plates 15. Multiple limiting components are provided inside each rotating block 12 to limit the left and right movement of the rotating block 12.

[0034] Each limiting component includes a fixed ring 13 and multiple springs 14. The outer wall of each fixed ring 13 is slidably connected to the inside of the rotating block 12 to limit the left and right movement of the rotating block 12. Each spring 14 is disposed inside the rotating block 12 to provide elastic force to the fixed ring 13. One end of each spring 14 is fixedly connected to the inside of the rotating block 12, and the other end of each spring 14 is fixedly connected to one side of the fixed ring 13. The rotating component includes a driving sprocket 8, a chain 9, and a driven sprocket 10. The inner wall of the driving sprocket 8 is rotatably connected to one end of the rotating shaft 5 to drive the chain 9 to rotate. The chain 9 is disposed on the outer walls of the driving sprocket 8 and the driven sprocket 10 to drive the driven sprocket 10 to rotate. The inner wall of the driven sprocket 10 is fixedly connected to one end of the connecting post 7 to drive the connecting post 7 to rotate. The outer walls of the driving sprocket 8 and the driven sprocket 10 are both engaged with the chain 9.

[0035] Specifically, when it is necessary to adjust the distance between the rotating blocks 12, the operator first holds the two rotating blocks 12 and pushes them to the left or right with both hands. During this process, the fixing ring 13 inside the rotating block 12 will contact the outer wall of the connecting column 7. As the rotating block 12 moves, the fixing ring 13 will be slowly squeezed into the rotating block 12. When the rotating block 12 moves to the required position, the operator stops pushing. At this time, the spring 14 inside the rotating block 12 will pop out the fixing ring 13 by its own elasticity. The popped-out fixing ring 13 will slide into the fixing groove 11 on the connecting column 7, thereby fixing the rotating block 12 on the connecting column 7 and ensuring that the rotating block 12 is accurately positioned.

[0036] Reference Figure 4 and Figure 5Each rotating block 12 has a fixed plate 15 fixedly connected to its bottom for fixing the fixed tube 16. Multiple fixed tubes 16 are fixedly connected inside each fixed plate 15 for fixing the air inlet 17 and the air guide tube 19. An air inlet 17 is fixedly connected to the top of each fixed tube 16 for air intake and exhaust. Multiple connecting grooves 18 are provided at the bottom of each fixed tube 16 to accommodate connecting strips 22 and limiting strips 23. An air guide tube 19 is fixedly connected inside each fixed tube 16 for air delivery. A sealing ring 20 is fixedly connected to the outer wall of each air guide tube 19 to seal the gap between the air guide tube 19 and the suction cup 21. A sliding connection is provided at the bottom of each fixed tube 16. The suction cup 21 is used to hold the ceramic blank. Each suction cup 21 has multiple connecting strips 22 fixedly connected to its top for connecting limiting strips 23. Each connecting strip 22 has a limiting strip 23 fixedly connected to its top to limit the movement range of the suction cup 21. Each limiting strip 23 has a fixing pin 24 slidably connected inside to fix the position of the suction cup 21. Each fixing pin 24 has a limiting plate 25 fixedly connected to its outer wall to limit the movement range of the fixing pin 24. Each connecting strip 22 has a spring 26 inside to provide elastic force to the fixing pin 24. One end of each spring 26 is fixedly connected inside the connecting strip 22, and the other end of each spring 26 is fixedly connected to the bottom end of the fixing pin 24.

[0037] Specifically, when the suction cup 21 needs to be replaced, the operator first holds the suction cup 21 and slowly rotates it clockwise. During this process, the limiting strip 23 at the top of the suction cup 21 will gradually disengage from the deepest part of the connecting groove 18. At the same time, the fixing pin 24 inside the limiting strip 23 will abut against the inner wall of the fixing tube 16. Under the continuous squeezing force of the inner wall of the fixing tube 16, the fixing pin 24 will slowly retract into the limiting strip 23. At this time, the suction cup 21 will be smoothly pushed out a short distance. Then, the operator holds the suction cup 21 and moves it vertically downward along the outer wall of the air guide tube 19, which will easily remove the suction cup 21 from the air guide tube 19. After disassembling and removing the old suction cup 21, the operator takes out the new suction cup 21, aligns the limiting strip 23 on its top with the position of the connecting groove 18, and inserts it into the connecting groove 18. When the limiting strip 23 reaches the innermost part of the connecting groove 18, the inner wall of the fixing tube 16 squeezes the fixing pin 24 again, forcing the fixing pin 24 to retract into the limiting strip 23. At this time, the operator rotates the suction cup 21 counterclockwise until the limiting strip 23 is firmly inserted into the deepest part of the connecting groove 18. At this moment, the spring 26 will use its own elasticity to pop out the fixing pin 24, so that it firmly locks the fixing tube 16. Thus, the replacement of the suction cup 21 is successfully completed.

[0038] Working principle: During the use of the blank transfer device, first adjust the distance between the rotating blocks 12 to the required spacing. Hold the two rotating blocks 12 and move them left or right, so that the inner fixing ring 13 is squeezed into the interior of the rotating block 12 by the outer wall of the connecting column 7. When the rotating block 12 moves to the required position, stop moving the rotating block 12, so that the inner fixing ring 13 pops out under the action of the spring 14 and slides into the fixing groove 11, fixing the rotating block 12 to the connecting column 7. Then, change the suction cup 21 to the required type. Hold the suction cup 21 and rotate it clockwise, so that the limiting strip 23 comes out from the deepest part of the connecting groove 18, and at the same time, the fixing pin 24 is squeezed by the inner wall of the fixing tube 16. The suction cup 21 is pushed out a short distance by retracting the limiting strip 23. Then, the suction cup 21 is held and moved downwards to remove it from the outer wall of the air guide tube 19. A new suction cup 21 is then taken out, and its top limiting strip 23 is aligned with the position of the connecting groove 18. The suction cup 21 is then inserted into the connecting groove. When the limiting strip 23 reaches the innermost part of the connecting groove 18, the inner wall of the fixing tube 16 presses the fixing pin 24 to retract it into the limiting block. Then, the suction cup 21 is rotated counterclockwise so that the limiting strip 23 is inserted into the deepest part of the sliding groove 18. At this time, the fixing pin 24 pops out under the action of the second spring 26 to fix the suction cup 21. The replacement of the suction cup 21 is now complete. After that, the equipment can be started to begin the blank transfer operation.
