Description

Technical Field

[0001] This utility model relates to the field of stone production technology, and in particular to a thickness-adaptive suction device for a fully automatic loading and unloading machine. Background Technology

[0002] The loading and unloading machine is an automated piece of equipment in marble slab processing. It is used to automatically load and unload slabs. Through a robotic arm and conveying device, the marble slabs are moved from the stacking area to the processing equipment. After processing, they are moved to the designated location. This can improve efficiency and reduce manual handling losses. It is used in the assembly line operation of stone processing plants.

[0003] Marble slabs vary in thickness, requiring different sizes to be accommodated by the upper and lower plate-mounting machines. The thickness-adaptive suction device can automatically adjust the suction cup height and suction force to ensure that slabs of different thicknesses can be stably gripped, avoiding poor gripping, damage, and equipment failure due to thickness deviations. This improves the compatibility and safety of automated production lines and reduces manual adjustment costs.

[0004] In the production and processing of sheet materials, manual handling of heavy sheets is inefficient and can lead to injuries due to improper operation, affecting production progress and safety. In existing technologies, automatic adsorption devices are used to adsorb and transport sheets, which can efficiently transfer heavy sheets, improve production efficiency and ensure operational safety. However, in actual use, the device will wear out and become clogged after long-term use, resulting in reduced suction, causing the sheets to fall, causing damage to the sheets and economic losses, and failing to effectively ensure the stability of sheet material handling. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a thickness-adaptive suction device for a fully automatic loading and unloading machine. It aims to improve the problem that in the prior art, long-term use of the device will cause wear and blockage, resulting in reduced suction, causing the board to fall, causing damage to the board and economic losses, and failing to effectively ensure the stability of board handling.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a fully automatic plate loading and unloading machine with a plate thickness adaptive suction device, comprising two frames, each frame having a carriage at its top, a suction mechanism at its top, the suction mechanism being used to suction moving plates, and an anti-sticking mechanism being provided on the top right side of the carriage, the anti-sticking mechanism being used to generate vibration to shake off excess plates. The suction mechanism includes a movable frame, a pressing component at the bottom of the movable frame, a suction plate frame at the bottom of the pressing component, multiple vacuum generators at the front and rear left ends of the suction plate frame, assembly components at the front and rear sides of the vacuum generators, multiple fixed seats at the bottom of the suction plate frame, fixing components at the top front and rear sides of the multiple fixed seats, rubber suction cups fixedly connected to the bottom of the multiple fixed seats, edge grooves on the outer bottom of the multiple rubber suction cups, and two disc holes at the bottom of the multiple rubber suction cups. Displacement components are provided on the left and right sides of the bottom of the frame, and material-bearing components are provided between adjacent frames. Pressing components are provided on the left and right sides of the bottom of the movable frame.

[0007] As a further description of the above technical solution: The anti-sticking mechanism includes two support plates, the bottom of which is fixedly connected to the top right side of the frame, and a cylinder is fixedly connected to the top of each support plate. A solenoid valve is fixedly connected to the top right side of the moving frame, and a push rod is fixedly connected to the left side of the cylinder. A sliding assembly is provided on the top of the frame.

[0008] As a further description of the above technical solution: The assembly includes two tie bolts, the outer sides of which are disposed on the inner sides of multiple vacuum generators, and mounting holes are provided on the front and rear sides of the multiple vacuum generators.

[0009] As a further description of the above technical solution: The fixing assembly includes multiple fixing plates, the bottoms of which are respectively fixedly connected to the front and rear sides of the top of multiple fixing seats, and fixing bolts are threadedly connected to the opposite sides of the multiple fixing plates.

[0010] As a further description of the above technical solution: The displacement assembly includes two traveling beams, the tops of which are fixedly connected to the bottom left and right sides of the frame, respectively, and multiple pulleys are rotatably connected to the inner sides of the two traveling beams.

[0011] As a further description of the above technical solution: The material receiving assembly includes multiple shelves, the left and right sides of which are fixedly connected between adjacent frames, and a wireless receiver is fixedly connected to the right side of the right frame.

[0012] As a further description of the above technical solution: The pressing assembly includes two hydraulic rods, the tops of which are fixedly connected to the left and right sides of the bottom of the movable frame, respectively, and the bottoms of both hydraulic rods are fixedly connected to mounting bases.

[0013] As a further description of the above technical solution: The sliding assembly includes two guide rails, the bottom of which is fixedly connected to the top of the frame, and multiple rollers are rotatably connected to the bottom inner side of the movable frame.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the hydraulic rod extends and retracts to move the mounting base and suction plate frame up and down. The vacuum generator generates negative pressure through the disc hole and the groove at the bottom of the rubber suction cup. The rubber suction cup adsorbs the plate, realizing the position and height adjustment of the suction mechanism, firmly adsorbing the plate, ensuring stable connection, ensuring the accuracy and reliability of the plate transfer process, avoiding wear and blockage of the device after long-term use, and effectively ensuring the stability of plate handling.

[0015] 2. In this utility model, the solenoid valve receives a signal and starts to control the operation of the cylinder at the top of the support plate, which pushes the push rod to extend and retract, acting on the moving frame. The rollers at the bottom of the moving frame roll on the guide rail. When the plate is released, the cylinder pushes the moving frame to produce a small displacement through the push rod, so that the rubber suction cup and the plate form a gap, realizing the smooth sliding and power control of the moving frame, destroying the adsorption force to prevent the plate from sticking, ensuring the anti-sticking effect without affecting the transfer accuracy, and ensuring a smooth plate release process.

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. Reference Figure 2 , Figure 4 and Figure 5 An embodiment of this utility model is provided: a thickness-adaptive suction device for a fully automatic loading and unloading machine, comprising two frames 1, each frame 2 is provided on the top of the two frames 1, a suction mechanism 3 is provided on the top of the frame 2, the suction mechanism 3 is used to suction moving plates, and an anti-sticking mechanism 4 is provided on the right side of the top of the frame 2, the anti-sticking mechanism 4 is used to generate vibration to shake off excess plates. The suction mechanism 3 includes a movable frame 31. A pressing assembly 312 is located at the bottom of the movable frame 31. A suction plate frame 32 is located at the bottom of the pressing assembly 312. Multiple vacuum generators 33 are located on the front and rear left ends of the suction plate frame 32. Assembly assemblies 38 are located on the front and rear sides of each vacuum generator 33. Each assembly assembly 38 includes two tie bolts 381. The outer sides of the two tie bolts 381 are located on the inner sides of the multiple vacuum generators 33. Mounting holes 382 are provided on the front and rear sides of each of the multiple vacuum generators 33. The bottom of the suction plate frame 32 is... There are multiple fixing seats 34, and fixing components 39 are provided on the front and rear sides of the top of the multiple fixing seats 34. The fixing components 39 include multiple fixing pieces 391. The bottom of the multiple fixing pieces 391 is fixedly connected to the front and rear sides of the top of the multiple fixing seats 34 respectively. The opposite sides of the multiple fixing pieces 391 are threaded with fixing bolts 392. The bottom of the multiple fixing seats 34 is fixedly connected with rubber suction cups 35. The bottom outer side of the multiple rubber suction cups 35 is provided with edge grooves 36. The bottom of the multiple rubber suction cups 35 is provided with two disc holes 37. The bottom left and right sides of the frame 2 are provided with displacement components 310. The displacement components 310 include two walking beams 3101. The tops of the two walking beams 3101 are fixedly connected to the bottom left and right sides of the frame 2 respectively. Multiple pulleys 3102 are rotatably connected to the inner sides of the two walking beams 3101. Material support components 311 are provided between the two adjacent frames 1. The material support components 311 include multiple storage racks 3111. The left and right sides of the multiple storage racks 3111 are fixedly connected to the adjacent sides of the two frames 1 respectively. A wireless receiver 3112 is fixedly connected to the right side of the right frame 1. The bottom left and right sides of the moving frame 31 are provided with pressing components 312. The pressing components 312 include two hydraulic rods 3121. The tops of the two hydraulic rods 3121 are fixedly connected to the bottom left and right sides of the moving frame 31 respectively. The bottoms of the two hydraulic rods 3121 are fixedly connected to mounting bases 3122. Specifically, when the suction mechanism 3 is working, the wireless receiver 3112 receives signals and transmits instructions. Multiple pulleys 3102 of the displacement component 310 rotate inside the traveling beam 3101, driving the frame 2 and the moving frame 31 to move above the shelf 3111 of the material receiving component 311. Through the cooperation of the pulleys 3102 and the traveling beam 3101, the position adjustment of the suction mechanism 3 is realized. When the pressing component 312 at the bottom of the movable frame 31 is activated, the two hydraulic rods 3121 extend and retract, driving the mounting base 3122 and the suction plate frame 32 at the bottom to move up and down, so that the rubber suction cup 35 at the bottom of the suction plate frame 32 is close to the object to be picked up. Through the cooperation of the hydraulic rods 3121 and the mounting base 3122, the height of the suction plate frame 32 can be adjusted. The vacuum generators 33 on the front and rear sides of the suction cup 32 work to generate negative pressure through the disc holes 37 at the bottom of the rubber suction cup 35, so that the rubber suction cup 35 tightly adsorbs the board. The edge grooves 36 enhance the adhesion between the suction cup and the board. Through the cooperation of the vacuum generator 33 and the rubber suction cup 35, the board is stably picked up. The tie bolts 381 of the assembly component 38 pass through the mounting holes 382 of the vacuum generator 33 to fix multiple vacuum generators 33 onto the suction plate frame 32. The fixing bolts 392 of the fixing component 39 pass through the fixing plate 391 to firmly connect the fixing seat 34 to the suction plate frame 32. The connection is stable through the cooperation of the tie bolts 381 and the fixing bolts 392.

[0019] Reference Figure 1 and Figure 3The anti-sticking mechanism 4 includes two support plates 41. The bottom of the two support plates 41 is fixedly connected to the top right side of the frame 2. The top of the two support plates 41 is fixedly connected to a cylinder 42. The top right side of the moving frame 31 is fixedly connected to a solenoid valve 43. The left side of the cylinder 42 is fixedly connected to a push rod 44. The top of the frame 2 is provided with a sliding assembly 45. The sliding assembly 45 includes two guide rails 451. The bottom of the two guide rails 451 is fixedly connected to the top of the frame 2. The bottom inner side of the moving frame 31 is rotatably connected to multiple rollers 452. Specifically, when the anti-sticking mechanism 4 is working, the solenoid valve 43 starts after receiving the control signal, controlling the cylinder 42 on the top of the two support plates 41 to operate. The cylinder 42 pushes the push rod 44 on the left side to extend and retract. The push rod 44 acts on the moving frame 31. Through the cooperation of the solenoid valve 43 and the cylinder 42, the power control of the push rod 44 is realized. When the movable frame 31 is subjected to force, multiple rollers 452 on the inner bottom side roll on the two guide rails 451 of the sliding assembly 45 at the top of the frame 2, driving the movable frame 31 to move along the direction of the guide rails 451. Through the cooperation of the rollers 452 and the guide rails 451, the movable frame 31 can slide smoothly. When the moving frame 31 moves the suction plate frame 32 and the rubber suction cup 35 to the designated position to release the plate, the cylinder 42 pushes the moving frame 31 to produce a small displacement through the push rod 44, so that a small gap is formed between the rubber suction cup 35 and the plate, which breaks the adsorption force between the two. Through the cooperation of the push rod 44 and the moving frame 31, the object to be picked up is prevented from sticking to the rubber suction cup 35. During the overall movement of the moving frame 31, the cooperation between the roller 452 and the guide rail 451 ensures the stability of the movement trajectory. The coordinated action of the cylinder 42 and the push rod 44 can adjust the thrust in a timely manner according to the characteristics of the part to be picked up, ensuring the anti-sticking effect without affecting the overall transfer accuracy, and realizing the control of the anti-sticking action.

[0020] Working principle: The wireless receiver 3112 on the right side of the right frame 1 receives the external control signal and transmits the signal to the equipment. The displacement component 310 responds immediately, and the multiple pulleys 3102 on the inner side of the two walking beams 3101 start to rotate. Since the top of the walking beam 3101 is fixedly connected to the bottom left and right sides of the frame 2, the rotation of the pulleys 3102 drives the frame 2 and the moving frame 31 installed on the frame 2 to move as a whole until it moves to the top of the multiple shelves 3111 of the material receiving component 311. The shelves 3111 are fixed on the left and right sides between the two adjacent frames 1, respectively, to provide a platform for the board to be picked up. When the pressing components 312 on the left and right sides of the bottom of the movable frame 31 are activated, the two hydraulic rods 3121 begin to extend and retract, and the mounting base 3122 fixedly connected to the bottom moves down and up accordingly, thereby driving the suction plate frame 32 at the bottom of the mounting base 3122 to move up and down, so that the rubber suction cups 35 connected to the multiple fixed seats 34 at the bottom of the suction plate frame 32 gradually approach the board on the shelf 3111. When the rubber suction cups 35 are close to the board, the multiple vacuum generators 33 on the left side of the front and rear sides of the suction plate frame 32 start to work, generating negative pressure through the two disc holes 37 at the bottom of the rubber suction cups 35. At the same time, the edge groove 36 on the outer side of the bottom of the rubber suction cups 35 increases the contact area with the surface of the board, enhancing the tightness of the adsorption, thereby achieving a stable adsorption of the board. During this process, the two tie bolts 381 of the assembly component 38 pass through the mounting holes 382 on the front and rear sides of the multiple vacuum generators 33, and firmly fix the vacuum generators 33 to the suction plate frame 32. The bottom of the multiple fixing plates 391 of the fixing component 39 are fixed to the front and rear sides of the top of the fixing base 34. The fixing bolts 392 with threads on the opposite side firmly connect the fixing base 34 and the suction plate frame 32, ensuring that there will be no loosening during suction and movement. When the equipment moves the sheet to the designated release position, the anti-sticking mechanism 4 starts working. The solenoid valve 43 on the top right of the moving frame 31 receives the control signal and starts, controlling the cylinder 42 on the top of the two support plates 41 to operate. The push rod 44 on the left side of the cylinder 42 extends and retracts accordingly. The push rod 44 acts on the moving frame 31, causing multiple rollers 452 on the inner bottom of the moving frame 31 to roll on the two guide rails 451 of the sliding assembly 45 on the top of the frame 2. This causes the moving frame 31 to produce a small displacement. This small displacement creates a tiny gap between the rubber suction cup 35 and the sheet, destroying the adhesion between them and effectively preventing the sheet from sticking to the rubber suction cup 35.

[0021] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
