Description

Technical Field

[0001] This application relates to the technical field of sheet material conveying, and in particular to a negative pressure adsorption type sheet material conveying device. Background Technology

[0002] Sheet metal transfer devices currently play a crucial role in modern industrial production. With the booming development of the manufacturing industry, these devices are widely used in numerous fields such as laser cutting and sheet metal processing. In these industries, frequent workpiece transfer is a vital part of daily production, and the emergence of sheet metal transfer devices has greatly improved the automation and efficiency of production. It makes the originally cumbersome workpiece transfer process more orderly and convenient, allowing companies to complete production tasks more quickly and reduce labor costs. At the same time, it can adapt to workpieces of different sizes and materials, providing strong support for diversified production by enterprises. It effectively ensures the integrity of thin sheets during transfer, reduces the defect rate, and thus improves the stability of the entire production process and product quality, playing a positive role in promoting the development of the industry.

[0003] In the past, the industry has employed various common technologies for sheet metal transfer. A more traditional approach involves using mechanical clamps to apply clamping force, securing the sheet metal, and then transferring it using cranes or similar equipment. This method is suitable for regularly shaped and large sheets, and is relatively simple and straightforward to operate. Some companies also use chain drives, placing the sheets on a chain and relying on the chain's movement to transport them, offering advantages in scenarios involving continuous sheet metal transport. Additionally, conveyor belts are another commonly used transfer tool. They can transport sheets smoothly and can flexibly adjust transport speed and direction according to actual needs, making them suitable for various production environments.

[0004] However, existing methods for transporting sheet materials have significant limitations. When dealing with long sheets, the transport process becomes extremely cumbersome. Traditional methods are ill-suited to the needs of transporting long sheets, and long sheets are prone to deformation during transport, affecting their quality and subsequent use. Utility Model Content

[0005] In order to enable flexible and safe transfer of longer sheets, this application provides a negative pressure adsorption type sheet conveying device.

[0006] The negative pressure adsorption type plate conveying device provided in this application adopts the following technical solution:

[0007] The negative pressure adsorption type sheet material conveying device includes a support device, a moving device, and an adsorption device. The support device includes two sets of frames, each set of frames including multiple support legs and load-bearing beams. The multiple support legs are spaced apart and are all vertically fixed to the ground. The load-bearing beams are horizontally set and fixed to the support legs. The two sets of frames form a symmetrical structure. The moving device includes a moving frame and a hook. The moving frame is horizontally set and slides on the two sets of load-bearing beams. The hook is vertically set. The movement of the moving frame and the hook forms a three-dimensional moving space. The adsorption device includes a connecting frame and multiple supports. The connecting frame is horizontally set and detachably connected to the hook. The multiple supports are all horizontally set and spaced apart along the length of the connecting frame. Each support has an adsorption unit at both ends. A control system for driving the movement of the moving device and adsorption of the adsorption device is fixedly connected to the connecting frame.

[0008] By adopting the above technical solution, the two sets of frames are symmetrically arranged, and the moving device and the adsorption device are placed between the two sets of support devices, which facilitates maintaining a stable balance when adsorbing the board. The moving frame and hook in the moving device can make the adsorption device move in three-dimensional space, which is convenient for the adsorption device to move in multiple angles and directions, increasing the flexibility of the board during transportation. In addition, when the connecting frame is set horizontally, multiple supports are arranged at intervals along the horizontal direction, and adsorption units are set at both ends of the supports, which increases the adsorption area of ​​the board, making it easier to adapt to longer boards and reducing the deformation problem of the board.

[0009] Optionally, the adsorption unit includes a suction cup base and a guide post. The suction cup base and the guide post are fixed, and the guide post is slidably connected to the bracket. The sliding direction is reciprocating in the vertical direction, and the suction cup base is a vacuum cavity.

[0010] By adopting the above technical solution, when the suction cup base contacts the plate, the guide column causes the base to float in the vertical direction, and the gas flow in the vacuum cavity can make the vacuum adsorption more uniform and stable.

[0011] Optionally, the inner layer of the suction cup base is interference-fitted with a sealing lip.

[0012] By adopting the above technical solution, the sealing lip deforms first when in contact with the board material, which can achieve pre-sealing and is easy to adapt to boards of different materials.

[0013] Optionally, the bracket has multiple mounting holes spaced apart along its length, and the guide rod passes through the mounting holes and connects to the bracket.

[0014] By adopting the above technical solution, the multiple mounting holes on the bracket can be used to adjust the position of the adsorption units at both ends, making it easy to adapt to boards of different widths.

[0015] Optionally, the control system includes a control panel and a control handle, the control handle being horizontally positioned and fixedly connected to the connecting frame, and the control panel being fixedly attached to the control handle.

[0016] By adopting the above technical solution, the staff can adjust the position of each bracket and adsorption unit on the connecting frame by driving the control handle, so as to adjust the adsorption device to the center position. Then, through the control panel, the position of the fixed moving device and the parameters of the adsorption device can be adjusted, making the board transfer work more stable and efficient.

[0017] Optionally, a handle is provided around the connecting frame and the support, and the handle is fixedly connected to the connecting frame.

[0018] By adopting the above technical solution, when adjusting the position of the adsorption unit, if the entire connecting frame is relatively large, the position of the connecting frame can be adjusted by using the handle and the support rod, so that the connecting rod can be centered more quickly and efficiently.

[0019] Optionally, multiple probes are spaced apart on the handle bar. The probes are slidably connected to the handle bar. When the handle bar is set horizontally, the sliding direction of the probes is vertical. Before the adsorption unit contacts the plate, the height of the bottom of the probe is lower than the height of the bottom of the suction cup base.

[0020] By adopting the above technical solution, the probe first contacts the board before the suction cup base adsorbs the board, and after contacting the board, the probe moves vertically upward, and then the suction base contacts the board. This can reduce the adhesion between multiple boards and cause other boards to fall and shift during the adsorption and transfer of the boards.

[0021] Optionally, a diagonal tie rod is fixed between two adjacent support legs of each frame group.

[0022] By adopting the above technical solution, the diagonal tie rod can increase the stability of two adjacent support legs.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The support device increases the overall stability of the equipment, and the moving device allows the adsorption device to move in three-dimensional space, increasing the flexibility of the board during transfer.

[0025] 2. When the suction cup base in the adsorption device comes into contact with the plate, a vacuum seal is formed. The internal vacuum cavity generates airflow, which causes the guide column to slide relative to the support, thereby improving the adsorption effect. The sealing lip first contacts the plate for pre-sealing, and it can also adapt to different plate materials.

[0026] 3. The control handle and handle bar on the connecting frame make it easy for staff to drive and control the adsorption device. When adsorbing long boards, it is easy to move to the center position and increase the stability of board transportation. Attached Figure Description

[0030] The following is in conjunction with the appendix Figures 1-2 This application will be described in further detail.

[0031] This application discloses a negative pressure adsorption type sheet material conveying device.

[0032] refer to Figure 1 The negative pressure adsorption type sheet conveying device includes a support device 1, a moving device 2, an adsorption device 3, and a control system 4. The support device 1 includes two sets of rectangular frames, which are symmetrically arranged in a box shape. Each set of frames includes multiple support legs 11 and load-bearing beams 12. The multiple support legs 11 are spaced apart and are all vertically fixed to the ground. The load-bearing beams 12 are horizontally arranged and fixed to the top of the support legs 11. Two diagonal tie rods 13 are fixed between two adjacent support legs 11. The two diagonal tie rods 13 are perpendicular to each other, which can increase the stability and safety of the support legs 11 and the load-bearing beams 12.

[0033] refer to Figure 1 The moving device 2 includes a moving frame 21 and a hook 22. The moving frame 21 has a grid structure and is set horizontally. A slide rail is fixed on the bearing beam 12. Rollers are rotatably connected to both ends of the moving frame 21. The rollers roll on the slide rail, thereby driving the moving frame 21 to slide on the bearing beam 12. Pressure rollers are also rotatably connected to both sides of the rollers. The rotation axis of the pressure rollers is set vertically. The pressure rollers are set on both sides of the slide rail and rotate in contact with the slide rail. This can assist the movement of the rollers and also prevent the moving frame 21 from detaching from the bearing beam 12.

[0034] The hook 22 is vertically set, and the top of the hook 22 is connected to the lift 23. The lift 23 can move along the X and Y axes on the grid of the moving frame 21. The lift 23 can drive the hook 22 to move vertically and can also increase the movement of the hook 22 on the Z axis, thereby realizing the free movement of the hook 22 in three-dimensional space. The moving frame 21 moves in a large direction on the supporting beam 12, and then drives the hook 22 to make fine displacement in three-dimensional space, thus making the adsorption and transportation of the board more flexible.

[0035] refer to Figure 1 and Figure 2 The adsorption device 3 includes a rectangular connecting frame 31 and multiple supports 32. The connecting frame 31 is horizontally arranged and detachably connected to the hook 22. The multiple supports 32 are all horizontally arranged and spaced apart along the length of the connecting frame 31. Each support 32 is arranged along the length of the connecting frame 31. Adsorption units 33 are provided at both ends of each support 32. A handle 5 is horizontally arranged around the connecting frame 31 and the supports 32. The handle 5 is rectangular and is fixed to the longer ends of the connecting frame 31.

[0036] The adsorption unit 33 includes a suction cup base 331 and a guide post 332. The support 32 has multiple mounting holes 321 spaced apart at both ends. The guide post 332 is vertically arranged and passes through the mounting holes 321, and is slidably connected to the mounting holes 321. The suction cup base 331 and the guide post 332 are fixed. The suction cup base 331 is a vacuum cavity. A gas storage tank is fixed on the connecting frame 31. The gas storage tank, the connecting frame 31, the support 32, the guide post 332 and the suction cup base 331 are all in gas communication. A vacuum cavity is formed inside the suction cup base 331. A spiral airflow channel is provided in the vacuum cavity. The spiral airflow channel can make the vacuum adsorption more uniform.

[0037] The outer surface of the suction cup base 331 is made of wear-resistant polyurethane material, and the inner layer of the suction cup base 331 is interference-connected with silicone sealing lip 3311, which makes the internal pressure of the suction cup base 331 more balanced. When adsorbing the board, the sealing lip 3311 can contact the board first and deform to achieve pre-sealing. It can not only adapt to different materials of board, but also automatically adjust the pressure inside the suction cup base 331, making the adsorption effect more stable.

[0038] refer to Figure 1 and Figure 2 The control system 4 includes a control panel 41 and a control handle 42. The control handle 42 is horizontally set and fixed along the length direction perpendicular to the connecting frame 31. The control handle 42 is located at the center of the connecting frame 31. The control panel 41 is fixed on the control handle 42. The control panel 41 and the control handle 42 are located on the outside of the handle bar 5, which makes it convenient for the staff to operate and control the connecting frame 31, so that the connecting frame 31 is located in the center of the plate. The staff can also hold the handle bar 5 to increase stability.

[0039] Multiple probes 51 are spaced along the length of the handlebar 5. The probes 51 are slidably connected to the handlebar 5. When the handlebar 5 is set horizontally, the sliding direction of the probes 51 is vertical. The bottom of the probes 51 is lower than the bottom of the suction cup base 331. Therefore, when the suction cup base 331 contacts the board, the probes 51 contact the board first. After contacting the board, the probes 51 rebound hydraulically, that is, slide upward relative to the handlebar 5. At this time, the suction cup base 331 then adsorbs the board. This can reduce the adhesion between two adjacent stacked boards and prevent the lower board from shifting during board transportation.

[0040] The implementation principle of the negative pressure adsorption type board conveying device in this application embodiment is as follows: When the board is being transferred, the operator holds the control handle 42 and operates the control panel 41. First, the position of the moving frame 21 on the bearing beam 12 is adjusted, and then the horizontal position and vertical height of the hook 22 are adjusted in detail so that the connecting frame 31 and the support 32 are roughly placed in the center of the board. When the adsorption unit 33 approaches the board, the probe 51 contacts the board first, and then the suction cup base 331 adsorbs the board. The probe 51 slides upward. The vacuum cavity in the suction cup base 331 is equipped with a spiral airflow, which can make the board adsorption effect better, so that the transfer is more stable and flexible.

[0041] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
