Description

Technical Field

[0001] The utility model relates to the technical field of material handling, in particular to a plate material handling device. Background Art

[0002] Different types of sheet materials are used in various types of automobiles, wherein a sheet material has protrusions 101 and grooves 102 arranged at intervals on its surface (e.g. Figure 1 As shown), for example, the cargo box panel of a pickup truck, and the protrusion heights of each protrusion 101 on the sheet may be different. In the prior art, the handling gripper for this type of sheet material uses an electromagnet to achieve adsorption of the sheet material, and the material adsorption surface of the electromagnet is arranged parallel to the surface of the sheet material. However, since the arrangement of the protrusions 101 and the grooves 102 and the protrusion heights are different for different types of sheets, when handling different types of sheets, the electromagnet and the protrusion 101 may not necessarily correspond without adjusting the installation position of the electromagnet, that is, the contact area between the electromagnet and the protrusion 101 may be small, while the area where the electromagnet is above the groove 102 is large, which will lead to a weakened adsorption capacity of the electromagnet for the sheet material, and the sheet material is easy to fall off from the handling device, and the handling efficiency is reduced. Utility Model Content

[0003] The utility model aims to at least solve the technical problem in the prior art that for plates of different specifications, the contact area between the electromagnet and the protrusion of the plate is small, resulting in a weakened adsorption capacity of the electromagnet on the plate and easy falling of the plate.

[0004] To this end, one purpose of the utility model is to propose a sheet material handling device, which includes a main frame, a suction mechanism, a correction mechanism and a first driving mechanism, the suction mechanism is installed at the bottom of the main frame, the correction mechanism and the first driving mechanism are respectively connected to the suction mechanism, the correction mechanism drives the suction mechanism to rotate and adjust the relative position of the sheet material and the suction mechanism, and the first driving mechanism drives the suction mechanism to pick up and place the sheet material after correction by the correction mechanism.

[0005] In some embodiments, the correction mechanism includes a driving member and a connecting shaft, the driving member is connected to the connecting shaft, the connecting shaft is rotatably connected to the suction mechanism, and the driving member drives the connecting shaft to rotate, thereby driving the suction mechanism to rotate.

[0006] In some embodiments, a return spring is also sleeved on the arc-shaped connecting member.

[0007] In some embodiments, the correction mechanism also includes a first sensor, which is arranged on the suction mechanism. The first sensor detects the flatness of the surface of the sheet material, and the driving member drives the suction mechanism to rotate to a position corresponding to the protrusion of the sheet material according to the flatness of the surface of the sheet material.

[0008] In some embodiments, the suction mechanism includes a suction box, a suction plate and a magnetic member, one end of the suction box is connected to the first driving mechanism, the other end of the suction box is movably connected to the suction plate, and the magnetic member is disposed in the suction box.

[0009] In some embodiments, the sheet material handling device also includes a clamping mechanism, which includes a second driving mechanism and a clamping jaw connected to the second driving mechanism, and the clamping jaw is installed on the main frame through a guide shaft. The second driving mechanism drives the clamping jaw to move along the guide shaft to clamp or release the sheet material.

[0010] In some embodiments, the main frame is provided with a slideway that cooperates with the guide shaft.

[0011] In some embodiments, there are multiple suction mechanisms, and the multiple suction mechanisms are installed around the main frame, and each suction mechanism is connected to one correction mechanism and one first driving mechanism.

[0012] In some embodiments, a robot mounting plate connected to the transport robot is provided on the top of the main frame.

[0013] The sheet material handling device provided by the embodiment of the utility model has the following beneficial effects:

[0014] (1) A suction mechanism is installed at the bottom of the main frame, and a correction mechanism and a first driving mechanism are installed at the suction mechanism. The correction mechanism can adjust the relative position between the suction surface of the suction mechanism and the sheet material to be transported. When transporting sheets of different specifications, the suction surface of the suction structure can be made to fit the protrusions on the sheet material as much as possible, so that the suction surface of the suction mechanism and the protrusions on the sheet material have a larger fitting area. After the correction mechanism is calibrated, the first driving mechanism drives the suction mechanism to pick up and place the sheet material, thereby ensuring the adsorption effect between the suction mechanism and the sheet material and improving the working efficiency of the transport gripper;

[0015] (2) When the suction surface of the suction mechanism contacts the sheet material, the driving member drives the connecting shaft to rotate, thereby adjusting the degree of contact between the suction surface and the sheet material. When transporting different sheets of material, the positional relationship between the suction surface of the suction mechanism and the sheet material can be quickly adjusted, saving operation time; at the same time, the connecting plate connected to the connecting shaft moves along the arc-shaped connecting member, making the movement of the correction mechanism more stable;

[0016] (3) The main frame is equipped with a clamping mechanism. Two clamping jaws symmetrically arranged along the main frame clamp the sheet from opposite sides to prevent it from falling off during the transportation of the sheet. The distance between the two symmetrical clamping jaws can be changed by the second driving mechanism, which can be suitable for clamping sheets of various specifications.

[0017] (4) A suction box and a suction plate are installed outside the magnetic part of the suction mechanism. The suction plate separates the magnetic part and the sheet material so that the magnetic part does not directly contact the sheet material, thereby preventing the sheet material from being unable to detach due to excessive suction force of the magnetic part.

[0033] It should also be understood that although the present invention has been described with reference to some specific examples, those skilled in the art will be able to realize many other equivalent forms of the present invention that have the features described in the claims and are therefore within the scope of protection defined thereby.

[0034] The above and other aspects, features and advantages of the present invention will become more apparent from the following detailed description when taken in conjunction with the accompanying drawings.

[0035] Specific embodiments of the present invention are described hereinafter with reference to the accompanying drawings; however, it should be understood that the embodiments applied for are merely examples of the present invention, which may be implemented in a variety of ways. Well-known and / or repeated functions and structures are not described in detail to avoid unnecessary or redundant details that obscure the present invention. Therefore, the specific structural and functional details applied for herein are not intended to be limiting, but merely serve as the basis and representative basis for the claims to teach those skilled in the art to use the present invention in a variety of ways with substantially any suitable detailed structure.

[0036] The first embodiment of the utility model provides a plate material handling device, such as Figure 2 As shown, the sheet material handling device includes a main frame 1, a suction mechanism 3, a correction mechanism 4 and a first driving mechanism 31. The suction mechanism 3 is installed at the bottom of the main frame 1. The correction mechanism 4 and the first driving mechanism 31 are respectively connected to the suction mechanism 3. The correction mechanism 4 drives the suction mechanism 3 to rotate and adjust the relative position of the sheet material 100 and the suction mechanism 3. The first driving mechanism 31 drives the suction mechanism 3 to pick up and place the sheet material 100 after correction by the correction mechanism 4.

[0037] The main frame 1 plays the role of supporting various components. When transporting the sheet material 100 with concave and convex surfaces, the sheet material transporting device moves as a whole to above the stacking area of ​​the sheet material 100, and the first driving mechanism 31 drives the suction mechanism 3 to move, suck up one of the sheets 100, and then transport it to other workstations for operation. When sucking the sheet material 100, since the surface of the sheet material 100 is concave and convex, the heights of the multiple protrusions 101 on the surface of the sheet material 100 may also be different. If multiple vacuum suction cup structures are used to adsorb the sheet material 100, some vacuum suction cups may be at the connection between the groove 102 of the sheet material 100 and the protrusion 101 of the sheet material 100. It is difficult to form a vacuum area between the vacuum suction cup and the sheet material 100, which affects the adsorption effect. If an electromagnet that is always placed horizontally with the sheet 100 is used to adsorb the sheet 100, when adsorbing sheets 100 of different specifications, for the same sheet 100, the heights of the protrusions 101 on the sheet 100 may not be consistent, and the contact area between the electromagnet and the protrusions 101 on the sheet 100 may be smaller, while the area above the grooves 102 on the sheet 100 is larger. In this case, the electromagnet has a weaker adsorption capacity for the sheet 100, and the sheet 100 is easy to fall off, resulting in low handling efficiency. Therefore, the correction mechanism 4 is installed on the suction mechanism 3. When the suction operation is performed, the main frame 1 gradually approaches the sheet material 100, and the suction surface of the suction mechanism 3 contacts the sheet material 100. The correction mechanism 4 drives the suction mechanism 3 to swing, and then adjusts the relative position between the suction surface of the suction mechanism 3 and the sheet material 100 to be adsorbed, so that the suction surface of the suction mechanism 3 is as close to the protrusion 101 of the sheet material 100 as possible, so that the suction surface of the suction mechanism 3 and the sheet material 100 are more closely fitted, thereby improving the suction effect on the sheet material 100 with an uneven surface (such as the cargo box panel of a pickup truck), thereby improving the handling efficiency.

[0038] In some embodiments, Figure 3As shown, the suction mechanism 3 includes a suction box 331 and a magnetic member 32. One end of the suction box 331 is connected to the first driving mechanism 31, and the magnetic member 32 is arranged in the suction box 331. Among them, the output end of the first driving mechanism 31 is connected to the magnetic member 32 to control the magnetic member 32 to rise or fall in the suction box 331. The cylinder of the first driving mechanism 31 is connected to the top of the suction box 331, and the bottom of the suction box 331 is an open structure. The suction box 331 supports the first driving mechanism 31. Specifically, after the first driving mechanism 31 is started, the suction box 331 is driven to move, and the magnetic member 32 in the suction box 331 moves accordingly. The magnetic member 32 gradually approaches the position of the sheet material 100. The closer the distance between the magnetic member 32 and the sheet material 100, the stronger the adsorption force, and the farther the distance between the magnetic member 32 and the sheet material 100, the weaker the adsorption force. The magnetic member 32 provides a guarantee for the adsorption force of the material suction mechanism 3, and the first driving mechanism 31 changes the adsorption force of the material suction mechanism 3 by changing the distance between the magnetic member 32 and the sheet material 100. For example, the first driving mechanism 31 is a cylinder; the magnetic member 32 is an electromagnet.

[0039] In some embodiments, the suction mechanism 3 further includes a suction plate 332, one end of the suction box 331 is connected to the first driving mechanism 31, the other end of the suction box 331 is movably connected to the suction plate 332, the suction box 331 and the suction plate 332 form a protective cover 33, the protective cover 33 surrounds the magnetic member 32, plays a protective role for the magnetic member 32, and the suction plate 332 can separate the magnetic member 32 from the sheet 100, so that the magnetic member 32 will not directly contact the sheet 100, and the magnetic member 32 will not scratch the sheet 100. Exemplarily, the suction plate 332 is a stainless steel plate.

[0040] Furthermore, if Figure 3 and Figure 4As shown, the lower part of the suction box 331 and one side of the suction plate 332 are movably connected so that the magnetic member 32 can be installed from the bottom of the protective cover 33. Specifically, the opposite sides of the suction plate 332 have support plates extending toward the suction box 331, and the support plate and the lower part of the suction box 331 are connected by a pin shaft to realize the movable connection between the suction plate 332 and the suction box 331, and the other end of the support plate can be connected to the side wall of the suction box 331 by a bolt. When installing the magnetic member 32, the suction plate 332 can be opened and installed from the bottom of the suction box 331 to improve the installation efficiency. When the sheet material 100 is adsorbed, the suction box 331 and the suction plate 332 can be closed, and the suction plate 332 plays a role in weakening the magnetic force of the magnetic member 32 on the sheet material 100, so as to avoid the strong magnetic member 32 being adsorbed on the sheet material 100 and unable to be detached normally. In addition, a baffle 333 is provided at one end of the suction plate 332 close to the pin shaft, and the baffle 333 is arranged to be inclined outward from the suction plate 332. When the protective cover 33 is opened, the baffle 333 limits the opening angle of the suction plate 332, so that the suction plate 332 does not need to be fully opened, thereby reducing the space occupied by the transport device in the longitudinal direction.

[0041] In addition, a limit switch is provided in the suction box 331, and the limit switch is arranged in the lower area of ​​the protective cover 33. The installation position of the limit switch is the absolute limit position of the movement of the magnetic part 32 in the protective cover 33. When the magnetic part 32 moves to the limit switch, it will no longer continue to move downward, so as to prevent the magnetic part 32 from extending out of the protective cover 33 and scratching the sheet material 100.

[0042] In some embodiments, Figure 4 and Figure 5 As shown, the correction mechanism 4 includes a driving member (not shown in the figure) and a connecting shaft 2, the driving member is connected to the connecting shaft 2, the connecting shaft 2 is rotatably connected to the material suction mechanism 3, and the driving member drives the connecting shaft 2 to rotate, thereby driving the material suction mechanism 3 to rotate. The driving member is installed on the main frame 1, and is used to drive the connecting shaft 2 to rotate. When the connecting shaft 2 rotates, the material suction mechanism 3 is driven to rotate, and the relative position between the material suction mechanism 3 and the sheet material 100 is adjusted, thereby changing the degree of fit between the suction surface of the material suction mechanism 3 (such as the suction plate 332) and the sheet material 100, so that the suction surface of the material suction mechanism 3 is more matched with the surface of the sheet material 100, so that the sheet material 100 can be smoothly transported.

[0043] Furthermore, the correction mechanism 4 further includes an arc-shaped connecting member 41 and a connecting plate 42, one end of the connecting plate 42 has a through hole, one end of the arc-shaped connecting member 41 passes through the through hole so that the connecting plate 42 is sleeved on the arc-shaped connecting member 41, and the other end of the connecting plate 42 is connected to the connecting shaft 2. When the connecting shaft 2 rotates, the connecting plate 42 is driven to move along the arc-shaped connecting member 41. The arc-shaped connecting member 41 and the connecting plate 42 are provided to make the rotation of the connecting shaft 2 more stable.

[0044] In some embodiments, a return spring 44 is also sleeved on the arc-shaped connecting member 41. When the sheet material 100 is separated from the material suction mechanism 3, the connecting plate 42 returns to the initial position under the elastic action of the return spring 44. For example, the initial position is the central position of the arc-shaped connecting member 41. The return spring 44 can realize the automatic return of the connecting plate 42 of the correction mechanism 4 without manual adjustment or adjustment by other structures.

[0045] In other embodiments, both ends of the arc-shaped connecting member 41 are connected to the limit seats 43, and the arc-shaped connecting member 41 is sleeved with a return spring 44, and both ends of the return spring 44 are respectively connected to the limit seats 43. The return spring 44 passes through the through hole of the connecting plate 42 and interferes with the hole wall of the through hole, so that the return spring 44 can also be driven to deform when the connecting plate 42 moves. On the one hand, the limit seat 43 can limit the distance that the connecting plate 42 moves along the arc-shaped connecting member 41, and on the other hand, the limit seat 43 is used to determine the installation position of the return spring 44. Exemplarily, the return spring 44 can be connected to the connecting plate 42.

[0046] In some embodiments, there are multiple suction mechanisms 3, and multiple suction mechanisms 3 are installed around the main frame 1, and each suction mechanism 3 is connected to a correction mechanism 4 and a first driving mechanism 31. Multiple suction mechanisms 3 are provided, and multiple positions of the sheet material 100 can be adsorbed, and the adsorption effect of the sheet material 100 is better.

[0047] In some embodiments, Figure 3 As shown, a support seat 5 is provided between the main frame 1 and the first driving mechanism 31, and one end of the connecting shaft 2 extends into the support seat 5 and is movably connected thereto. The support seat 5 supports the first driving mechanism 31 and ensures the smooth rotation of the connecting shaft 2.

[0048] In some embodiments, the correction mechanism 4 further includes a first sensor, which is disposed on the suction mechanism 3. The first sensor detects the flatness of the plate surface of the sheet material 100. The driving member drives the suction mechanism 3 to rotate to a position corresponding to the protrusion 101 of the sheet material 100 according to the flatness of the plate surface. Specifically, the first sensor is installed on the suction box 331. The first sensor can detect the flatness of the plate surface. If the flatness of the sheet material 100 reaches a preset threshold, it means that the sheet material 100 and the suction plate 332 are closely attached. The driving member stops working and the correction of the correction mechanism 4 ends. If the flatness of the sheet material 100 exceeds the preset threshold, it means that the sheet material 100 and the suction plate 332 are not closely attached. The driving member drives the connecting shaft 2 to rotate, and the correction mechanism 4 adjusts the relative position between the sheet material 100 and the suction plate 332.

[0049] A signal switch is installed on the main frame 1 to transmit the material suction state and material discharge state to the controller to realize the automatic operation of material suction and material discharge.

[0050] In other embodiments, after the suction mechanism 3 sucks up the sheet material 100, the relative position between the correction mechanism 4 and the sheet material 100 is manually adjusted so that the suction plate 332 fits tightly against the sheet material 100, and then the sheet material 100 is transported to the next workstation by the sheet material handling device.

[0051] In some embodiments, Figure 6 As shown, the sheet material handling device further includes a clamping mechanism 6, which includes a second driving mechanism 62 and a clamping jaw 61 connected to the second driving mechanism 62, the clamping jaw 61 being mounted on the main frame 1 via a guide shaft 64, and the second driving mechanism 62 driving the clamping jaw 61 to move along the guide shaft 64 to clamp or release the sheet material 100. The clamping mechanism 6 is symmetrically arranged along the main frame 1, and the second driving mechanism 62 can drive the clamping jaw 61 to move, thereby adjusting the distance between the two symmetrical clamping jaws 61, which can adapt to clamping sheets 100 of different specifications, thereby improving the application range of the handling device.

[0052] Since the length of the clamping jaw 61 is generally long, when the clamping jaw 61 moves under the action of the second driving mechanism 62, the guide shaft 64 guides the movement of the clamping jaw 61, so that the clamping jaw 61 moves more smoothly.

[0053] In some embodiments, a guide hole is provided on the clamp 61 for cooperating with the guide shaft 64, and a positioning hole is also provided on the clamp 61 for cooperating with the output end of the second drive mechanism 62. The positioning hole can be connected to the guide hole to improve the processing efficiency of the clamp 61, and also improve the installation efficiency of the clamp 61, the second drive mechanism 62 and the guide shaft 64.

[0054] In some embodiments, the other end of the clamping jaw 61 has a bent portion 63 bent toward the suction mechanism 3. The bent portion 63 supports the sheet material 100, increases the contact area between the clamping jaw 61 and the sheet material 100, and during the clamping operation, the clamping is more stable and the sheet material 100 is not easy to fall off from between the two clamping jaws 61.

[0055] Exemplarily, the clamping mechanism 6 is provided with two groups, each group having clamping claws 61 symmetrically arranged along the main frame 1. The clamping mechanism 6 clamps the sheet material 100 from both sides thereof, thereby improving the stability of the sheet material 100 during transportation.

[0056] In some embodiments, Figure 7 As shown, the main frame 1 is provided with a slideway 67 that cooperates with the guide shaft 64. The slideway 67 is provided to facilitate adjustment of the position of the clamping jaw 61 along the length direction of the main frame 1, which is conducive to adapting to the clamping of the sheet materials 100 with different length specifications.

[0057] The main frame 1 is composed of aluminum alloy parts, which makes the sheet material handling device lightweight. If it is carried on a handling robot for operation, the load of the handling robot can be reduced. In addition, the aluminum alloy material makes it easy to install during splicing, and each splicing piece is connected by bolts, which is convenient for adjusting the distance between each splicing piece.

[0058] In some embodiments, Figure 8 As shown, a robot mounting plate 7 connected to a handling robot is provided on the top of the main frame 1, so that the sheet material handling device can realize on-site operation with the action of the handling robot. For example, the robot mounting plate 7 is made of metal material.

[0059] In other embodiments, a handle 8 is installed at the lower part of the main frame 1. The operator can also manually carry the carrying device to a position above the sheet material 100 through the handle 8 to further implement the material suction and discharge operations.

[0060] The working process of the sheet material handling device is:

[0061] (1) The sheet material 100 (such as a cargo box panel) is concave and convex alternately. When the sheet material 100 is stamped, the drawing liquid causes the sheet material 100 to stick together and multiple sheets 100 are stacked, resulting in no gaps between the sheets 100. A separate separator is used to separate each sheet material 100;

[0062] (2) The handling robot moves the sheet material handling device installed on the robot mounting plate 7 to a position above the sheet material 100, and the first driving mechanism 31 drives the magnetic member 32 to move toward the sheet material 100, and the magnetic member 32 is energized. The energized magnetic member 32 acts on the suction plate 332. When the suction plate 332 contacts the sheet material 100, the driving member enables the correction mechanism 4 to continuously adjust the positional relationship between the suction plate 332 and the sheet material 100. Further, the clamping claw 61 of the clamping mechanism 6 clamps the four sides of the sheet material 100. At this point, the sheet material 100 is fixed to the suction mechanism 3 to achieve suction.

[0063] (3) The transport robot transfers the sheet material transport device to the next station, the magnetic part 32 is powered off, the suction mechanism 3 and the sheet material 100 are released from adsorption, and the second drive mechanism 62 of the clamping mechanism 6 changes the position of the clamping claw 61 to release the sheet material 100, thereby releasing the material.
