Abstract
Description
Technical Field
[0001] This invention relates to the field of vacuum suction cup material handling technology, and in particular to a highly adaptable vacuum suction cup material handling device. Background Technology
[0002] A vacuum suction cup, or simply a suction cup, is an actuating element that operates by reducing the air pressure in a temporary sealed space formed after contact with a workpiece, utilizing the pressure difference. First, the vacuum suction cup is connected to a vacuum device via a connecting pipe. Then, it comes into contact with the object to be lifted, such as glass or paper. The vacuum device is activated, creating negative pressure inside the suction cup, thus firmly holding the object in place. Once the object is reached, air is smoothly injected into the vacuum suction cup, changing the negative pressure to zero or slightly positive pressure. The vacuum suction cup then detaches from the object, thus completing the task of lifting and moving heavy objects.
[0003] Authorization announcement number CN201910314814.5 discloses a glass raw material picking mechanism, process, and a segmented loading and unloading robot. When the support arm moves the picking bracket until the vacuum suction cup contacts and adsorbs the glass raw material, the support arm then raises the picking bracket slightly. At this point, one or more pieces of glass raw material may be attached to the top layer and picked up simultaneously. The pushing mechanism then drives the pusher to apply a pushing force to the middle position of the glass raw material, causing it to bend and deform. Simultaneously, air is blown onto the glass raw material from the side. Under the combined action of gravity and differential airflow pressure, the lower glass material is separated from the upper glass material, thus achieving the slicing action. Compared with the prior art, the structure of this invention is simpler and avoids grabbing multiple pieces of material at the same time. In practical applications, multiple material picking brackets can be set on each support arm, which helps to improve the efficiency of material picking and better meets the application requirements. However, the device has the following problems: First, it is easy to fall off when transporting irregularly shaped items, and the adsorption is not strong enough. Second, during the movement process when the vacuum suction cup is picking up the material, the inertia can easily cause unstable conveying. Summary of the Invention
[0004] The purpose of this invention is to address the shortcomings of existing technologies by using a sliding plate and a second sliding plate to keep the lower vacuum suction cup assembly and the second sliding plate in a relatively stationary state. This reduces the impact of inertia on the tightness of the connection between the silicone rubber suction cup and the transported item during the transportation process, thereby solving the technical problems of unstable transportation, easy item detachment, and insufficient adsorption.
[0005] To achieve the above objectives, the present invention provides the following technical solution:
[0006] A highly adaptable vacuum suction cup material handling device includes a slide rod, a cylinder is provided at the upper right end of the slide rod, and a telescopic rod is provided at the left side of the cylinder. A slide plate is fixedly connected to the left side of the telescopic rod, and the slide plate is slidably connected to the slide rod.
[0007] A sliding plate is provided with an electric rotating shaft at its center. The lower end of the electric rotating shaft is connected to a second sliding plate by a bearing. The lower end of the second sliding plate is slidably connected to a second sliding rod. The left and right sides of the second sliding plate are provided with identical vacuum suction cup assemblies. The vacuum suction cup assemblies are slidably connected to the second sliding rod. The leftmost end of the second sliding rod is fixedly connected to a limiting structure. An adjusting power device is provided on the rear side of the limiting structure.
[0008] As a preferred embodiment, the vacuum suction cup assembly includes a fixed rod, a second sliding plate is fixedly connected to the right side of the fixed rod, and two fixed sliding sleeves of the same structure are fixedly connected to the left side of the fixed rod. The fixed sliding sleeves are slidably connected to a second sliding rod, and two identical arched blocks are fixedly connected to the lower end of the fixed sliding sleeves. A second electric rotating shaft is connected to the bearing inside the arched block, and four identical vacuum suction cups are wrapped around the outer surface of the second electric rotating shaft.
[0009] As a preferred embodiment, the vacuum suction cup includes a tightening and fixing ring, the lower end of which is fixedly connected to the main arm, the lower end of which is fixedly connected to the steering block, the lower end of which is movably connected to the support arm, and the lower end of which is fixedly connected to the silicone rubber suction cup.
[0010] As a preferred embodiment, the main boom and the outrigger are hollow inside, and the steering block includes a main fixed block and a third electric rotating shaft. The main fixed block is fixedly connected to the main boom, and the third electric rotating shaft is bearing-connected to the main fixed block and fixedly connected to the outrigger.
[0011] As a preferred embodiment, both the slide bar and the second slide bar are composed of two identical circular tubes, and the circular tubes are arranged in parallel front to back.
[0012] As a preferred embodiment, the limiting structure includes two limiting blocks with the same structure. A circular hole is provided at the center of each limiting block. The circular hole is fitted onto the second slide rod and is fixedly connected to the second slide rod. A through hole is also provided at the upper end of each limiting block. A stabilizing distance tube is fixedly connected inside the through hole. The front end and rear end of the stabilizing distance tube are both fixedly connected to the limiting block.
[0013] As a preferred embodiment, the adjusting power device includes an adjusting cylinder, with a fine-tuning telescopic rod connected to the right side of the adjusting cylinder, and a fixed sliding sleeve at the closest distance to the fine-tuning telescopic rod fixedly connected to the right side of the telescopic rod.
[0014] As a preferred embodiment, the four vacuum suction cups on the second electric rotating shaft are distributed in pairs on both sides of the second slide rod.
[0015] As another preferred embodiment, the silicone rubber suction cup has a suction hole at its center, and the upper end of the suction hole is connected to an air tube. The air tube is placed inside the support arm. Both the support arm and the main arm have hollow internal structures. An air tube hole is opened on one side of both the support arm and the main arm. The air tube passes through the air tube hole to achieve a hidden placement from the support arm to the main arm.
[0016] The beneficial effects of this invention are:
[0017] (1) In this invention, a cylinder is set to drive the telescopic rod to extend and retract, thereby driving the slide plate to slide on the slide rod. The movement of the slide plate will drive the second slide plate directly below it to slide on the second slide rod. Moreover, the slide plate and the second slide plate are connected by an electric rotating shaft. Therefore, when the electric rotating shaft is energized and rotated, it can drive the second slide plate to rotate in the left and right directions. The left and right and tilt angles can be controlled. During the process of vacuum suction cups at the upper end to pick up irregularly shaped materials, the overall center of gravity can be controlled by adjusting the angle of the suction cups, making the material conveying more stable.
[0018] (2) In this invention, by setting a limiting structure, a limiting block is set at the leftmost position of the second slide rod. In this way, the slide plate will also be affected by the limiting block because of the connection between the slide plate and the second slide plate. It will not be unable to limit the slide rod because there is no limiting block at the top of the slide rod. The safety factor is high and the cost can be saved at the same time.
[0019] (3) In this invention, by setting up a vacuum suction cup group, the angle of the main arm and the support arm can be adjusted by the second electric rotating shaft and the third electric rotating shaft, thereby adjusting the contact position of the silicone rubber suction cup on the material to be picked up, so that the overall silicone rubber suction cup is close to the center of gravity for picking up and conveying, and can pick up materials of different shapes, with a wider range of applications.
[0020] In summary, this equipment has the advantages of being suitable for picking up irregularly shaped materials and providing more stable conveying, and is especially suitable for the field of vacuum suction cup material handling technology. Attached Figure Description

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0029] Example 1
[0030] like Figures 1 to 6 As shown, the present invention provides a highly adaptable vacuum suction cup material handling device, including a slide rod 1, a cylinder 2 is provided at the upper right end of the slide rod 1, and a telescopic rod 3 is provided at the left side of the cylinder 2. The left side of the telescopic rod 3 is fixedly connected to a slide plate 4, and the slide plate 4 is slidably connected to the slide rod 1.
[0031] The slide plate 4 has an electric rotating shaft 41 at its center. The lower end of the electric rotating shaft 41 is connected to the second slide plate 42 by a bearing. The lower end of the second slide plate 42 is slidably connected to the second slide rod 43. The left and right sides of the second slide plate 42 are provided with the same vacuum suction cup group 5. The vacuum suction cup group 5 is slidably connected to the second slide rod 43. The leftmost end of the second slide rod 43 is fixedly connected to the limiting structure 7. The limiting structure 7 is provided with an adjusting power device 6 on its rear side.
[0032] Furthermore, such as Figure 5 As shown, the vacuum suction cup assembly 5 includes a fixed rod 51. The right side of the fixed rod 51 is fixedly connected to a second sliding plate 42, and the left side of the fixed rod 51 is fixedly connected to two fixed sliding sleeves 52 with the same structure. The fixed sliding sleeves 52 are slidably connected to a second sliding rod 43, and the lower end of the fixed sliding sleeves 52 is fixedly connected to two identical arched blocks 53. The inner bearing of the arched block 53 is connected to a second electric rotating shaft 54. The outer surface of the second electric rotating shaft 54 is wrapped with four identical vacuum suction cups 55. The second sliding plate 42 is fixedly connected to the fixed rod 51, and the fixed rod 51 is connected to two fixed sliding sleeves 52 placed on the left and right sides, so that the second sliding plate 42 can synchronously drive the fixed sliding sleeves 52 to slide on the second sliding rod 43 during the sliding process.
[0033] Eight fixed sliding sleeves 52 are provided, with four of them set on a second sliding rod 43. Moreover, the four fixed sliding sleeves 52 on each second sliding rod 43 are distributed in pairs on the left and right sides of the second sliding plate 42 to ensure overall coordination and uniformity.
[0034] The arched block 53 is threadedly connected to the fixed sliding sleeve 52, and a second electric bearing 54 is provided between the arched block 53 and the fixed sliding sleeve 52. The second electric bearing 54 limits the second sliding rod 43 at the front and rear ends, and makes the fixed sliding sleeve 52 at the front and rear ends move synchronously. It can also drive the vacuum suction cup 55 fixedly connected to it to be fixedly connected, thereby adjusting the angle of the main arm 552. The overall movement is uniform, and it has multiple functions and a simple principle.
[0035] Furthermore, such as Figure 2 As shown, the vacuum suction cup 55 includes a tightening and fixing ring 551. The lower end of the tightening and fixing ring 551 is fixedly connected to the main arm 552. The lower end of the main arm 552 is fixedly connected to the steering block 553. The lower end of the steering block 553 is movably connected to the support arm 554. The lower end of the support arm 554 is fixedly connected to the silicone rubber suction cup 555. The tightening and fixing ring 551 is used to fix the position of the main arm 552. When the second electric rotating shaft 54 rotates, it can drive the tightening and fixing ring 551 and the main arm 552 fixedly connected to it to adjust their positions. The steering block 553 is used to limit the position of the support arm 554 and adjust the angle of the support arm 554.
[0036] The silicone rubber suction cup 555 is made of silicone rubber, which is very suitable for gripping products with rough surfaces. This provides sufficient friction for stable gripping when picking up plastic parts in automotive interiors.
[0037] Furthermore, the main arm 552 and the support arm 554 are hollow inside. The steering movable block 553 includes a main body fixing block 556 and a third electric rotating shaft 557. The main body fixing block 556 is fixedly connected to the main arm 552. The third electric rotating shaft 557 is connected to the main body fixing block 556 by a bearing and is also fixedly connected to the support arm 552, which allows for position adjustment of the support arm 552.
[0038] Furthermore, both the slide rod 1 and the second slide rod 43 are composed of two identical round tubes, which are arranged in parallel front to back. The two round tubes are used to balance the position distribution of the slide plate 4 and the second slide plate 42. Moreover, a cylinder 2 is provided at the right end of the slide rod 1, which not only has a limiting effect on the right side, but also provides sliding power for the slide plate 4, achieving multiple benefits in one go.
[0039] Furthermore, such as Figure 4As shown, the limiting structure 7 includes two limiting blocks 71 with the same structure. A circular hole is provided in the center of the limiting block 71. The circular hole is sleeved on the second slide rod 43 and fixedly connected to the second slide rod 43. A through hole is also provided at the upper end of the limiting block 71. A stabilizing distance tube 72 is fixedly connected in the through hole. The front end and the rear end of the stabilizing distance tube 72 are fixedly connected to the limiting block 71. The function of the limiting block 71 is to limit the position on the left side to prevent the second slide plate 42 from falling off the left side and thus creating unnecessary safety hazards.
[0040] Because the slide plate 4 and the second slide plate 42 are on the same straight line through the electric rotating shaft 41, and the electric rotating shaft 41 limits the position of the slide plate 4 and the second slide plate 42, as long as the position of the second slide plate 42 is limited, the slide plate 4 at its upper end will also be limited, so there will be no risk of falling and the occurrence of safety hazards will be reduced.
[0041] Furthermore, such as Figure 4 As shown, the adjusting power device 6 includes an adjusting cylinder 61. The right side of the adjusting cylinder 61 is connected to a fine-tuning telescopic rod 62. The right side of the fine-tuning telescopic rod 62 is fixedly connected to a fixed sliding sleeve 52 at the closest distance to it. The adjusting cylinder 61 provides a telescopic force to the fine-tuning telescopic rod 62. The fine-tuning telescopic rod 62 only needs to be connected to a fixed sliding sleeve 52 to achieve fine-tuning of the position of the entire vacuum suction cup assembly 5. This allows the vacuum suction cup 55 on it to better control the center of gravity of the material, thereby achieving more stable suction. Moreover, the adjusting cylinder 61 and the cylinder 2 can also operate simultaneously. This way, the adjusting cylinder 61 will not fail due to the pulling of the fine-tuning telescopic rod 62 during the operation of the cylinder 2.
[0042] Furthermore, such as Figure 5 As shown, the four vacuum suction cups 55 on the second electric rotating shaft 54 are distributed in pairs on both sides of the second slide bar 43. The reasonable placement of the vacuum suction cups 55 makes the contact area of the silicone rubber suction cups 555 larger, the distribution more reasonable, and the suction more stable when they pick up materials.
[0043] Furthermore, such as Figure 3As shown, the silicone rubber suction cup 555 has a suction hole at its center. The upper end of the suction hole is connected to an air pipe 8, which is placed inside the support arm 554. Both the support arm 554 and the main arm 552 are hollow structures. An air pipe hole is opened on one side of both the support arm 554 and the main arm 552. The air pipe 8 passes through the air pipe hole to achieve a hidden placement from the support arm 554 to the main arm 552. The suction hole connects to the air pipe 8. The air pipe 8 is first hidden inside the support arm 554, then it passes through the air pipe hole on the upper side of the support arm 554 and is exposed to the air. Next, it passes through the air pipe hole on the main arm 552 and enters the inner side of the main arm 552. It passes through the air pipe hole on the upper side of the main arm 552 again and is exposed to the air. Finally, it passes into the second slide rod 43 and is connected to an external air compressor through the second slide rod 43, thereby realizing the vacuum suction function of the silicone rubber suction cup 555 and hiding the air pipe 8, making the overall appearance better.
[0044] Secondly, an infrared sensor is installed at the upper end of the support arm 554, which can change the absorption efficiency and make adsorption more convenient.
[0045] Working process: First, cylinder 2 starts to move, driving slide 4 to slide on slide rod 1. When it slides to the corresponding position, electric shaft 41 starts to rotate to adjust the angle position of second slide 42. During the movement of slide 4, due to the connection between electric shaft 41 and second slide 42, slide 4 will also drive second slide 42 to slide on second slide rod 43, so as to realize the adjustment of angle and position in a large direction.
[0046] Secondly, the adjusting cylinder 61 in the adjusting power unit 6 drives the fine-tuning telescopic rod 62 to extend and retract, so that the fine-tuning telescopic rod 62 can drive the fixed sliding sleeve 52 to slide on the second sliding rod 43, so that the overall position is finely adjusted and more accurate.
[0047] Then the vacuum suction cup assembly 5 starts working. The second electric rotating shaft 54 drives the main arm 552 to adjust the height and angle, and the third electric rotating shaft 557 drives the support arm 554 to fine-tune the angle, so that the silicone rubber suction cup 555 can be perpendicular to the material surface. Considering that the tilt of each surface of the irregular material is different, each third electric rotating shaft 557 is controlled separately to ensure that the overall suction is more stable.
[0048] It is worth noting that the main arm 552, the support arm 557, the slide bar 1, and the second slide bar 43 are all hollow. This allows the wiring and air pipes 8 to be concealed internally, ensuring overall aesthetics and preventing unnecessary wiring from affecting the suction of the vacuum suction cup. Furthermore, during the sliding process, there is no inertia affecting the tightness of the connection between the material and the silicone rubber suction cup 555. Under normal circumstances, when the vacuum suction cup pauses during transport, the material is affected by inertia, causing it to detach from the vacuum suction cup. Therefore, by designing two slide bars, one above the other, the entire structure can be driven to slide. In this way, the inertia will act on the slide bar 4 and the second slide bar 42, without affecting the material and the silicone rubber suction cup 555, making the overall transport more stable and reliable.
