Description

Technical Field

[0001] This application relates to the field of sheet metal gripping and transportation technology, specifically a stamped sheet metal gripping and transportation device. Background Technology

[0002] Stamped sheet metal is the raw material used in the stamping process. It refers to metal or non-metal sheets that are made into various parts through stamping. Stamped sheet metal is widely used in industries such as automobiles, home appliances, and construction. It can adapt to the production of parts with different shapes, sizes, and performance requirements, supporting diversified product designs. After production, stamped sheet metal needs to be transported and stored. In order to improve the production rate of stamped sheet metal, stamped sheet metal clamping and transport equipment is required. Its main purpose is to quickly and accurately position the finished stamped sheet metal, and then clamp it with a robotic arm or other clamps to achieve the clamping and handling of the stamped sheet metal, reducing human operation errors and shortening the production cycle. Stamped sheet metal clamping and transport equipment is particularly suitable for multi-station, high-precision stamping scenarios.

[0003] Existing stamped sheet metal clamping and transport equipment typically consists of mechanical grippers, transport tracks, and drive devices such as cylinders. When it is necessary to clamp and transport stamped sheet metal, the mechanical grippers first position and clamp the stamped sheet metal. Then, the cylinders are activated, and the cylinders drive the mechanical grippers to slide on the transport tracks, thereby moving the stamped sheet metal. This achieves the purpose of positioning, gripping, and transporting the stamped sheet metal.

[0004] Although the above-mentioned device achieves the clamping and transportation of stamped sheets, since stamped sheets are used in many different fields, and different fields have different requirements for the material and thickness of stamped sheets, existing stamped sheet clamping and transportation equipment usually uses mechanical clamps or robotic arms to clamp the stamped sheets. When it is necessary to clamp and transport stamped sheets that are heavier or thicker, the mechanical clamps may damage the stamped sheets because they cannot adjust the clamping thickness. Furthermore, when clamping heavy stamped sheets, there is no auxiliary clamping equipment, which may lead to unstable clamping. Therefore, it is necessary to provide a stamped sheet clamping and transportation device to solve the above problems.

[0005] It should be noted that the information disclosed in this background section is only for understanding the background technology of this application concept, and therefore may include information that does not constitute prior art. Summary of the Invention

[0008] Furthermore, the frame body is provided with a horizontal tube, and a slide rail is slidably installed at the bottom of the horizontal tube. A drive cylinder is provided on one side of the slide rail. One set of upper clamping units is fixedly connected to the slide rail, and another set of upper clamping units is fixedly connected to the bottom of the horizontal tube.

The upper clamping plate is fixedly installed at the bottom of the transition plate. The lower clamping unit also includes a connecting tube. A side plate is provided on the corresponding side of the connecting tube. The lower clamping plate is slidably installed on the corresponding side of the side plate.

[0009] Furthermore, at least two sets of adjusting bolts are threaded onto one side of the support plate, and at least two sets of adjusting holes are provided on the side plate, with one end of the adjusting bolt adapted to be inserted into the adjusting hole.

[0010] Furthermore, a soft pad is fixedly installed on the top of the lower clamping plate, and soft pads are fixedly installed on both sides of the bottom of the upper clamping plate.

[0011] Furthermore, a lifting assembly is provided at the bottom of the frame. The lifting assembly includes a base plate fixedly installed at the bottom of the frame, a sliding plate slidably installed on the top of the base plate, a lifting cylinder fixedly installed on the top of the sliding plate, and a lifting plate fixedly installed on the output end of the lifting cylinder.

[0012] Furthermore, buffer components are fixedly installed at the four corners of the top of the skateboard. The buffer components include an outer cylinder fixedly installed on the skateboard. The outer cylinder is hollow inside and an inner cylinder is installed inside the outer cylinder. The top of the inner cylinder is fixedly connected to the top of the support plate, and a spring is fixedly installed at the bottom of the inner cylinder.

[0013] Furthermore, at least two sets of lower suction cups are fixedly installed on the lifting plate.

[0014] Furthermore, a flexible pad is fixedly installed on the support plate.

[0015] Furthermore, a top plate is fixedly installed on the top of the frame, a crossbar is slidably installed on the bottom of the top plate, two sets of hangers are slidably installed on the bottom of the crossbar, a connector is fixedly installed on the bottom of the hanger, the bottom of the crossbar is fixedly connected to the bottom of the connector, a support bar is fixedly installed on the upper end of one side of the frame, one side of the bottom of the crossbar is slidably connected to the top of the support bar, and a first cylinder is fixedly installed on the bottom of the top plate, the output end of the first cylinder is fixedly connected to the crossbar.

In the subsequent clamping process, the clamp can clamp the stamping sheet with a thicker thickness. In addition, by setting an upper suction cup, when clamping the stamping sheet, the upper suction cup picks up the middle of the stamping sheet, the clamp clamps the two sides of the stamping sheet, and the upper suction cup provides auxiliary clamping of the stamping sheet. Thus, the stamping sheet clamping and transporting device clamps and transports heavier stamping sheets more stably. Secondly, it is also equipped with a lifting plate, a lifting cylinder, and a sliding plate. When clamping the stamped sheet, the lifting plate can lift the stamped sheet to the clamping position, making it convenient for the fixture to clamp the stamped sheet. The lifting plate can also lift the bottom of the stamped sheet, thus avoiding the situation where the middle of the stamped sheet is not well supported behind the fixture. In the subsequent conveying process, the sliding plate slides synchronously with the fixture, continuously lifting the stamped sheet, making the clamping and conveying of the stamped sheet more stable and improving the stability of the stamped sheet clamping and conveying equipment.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0022] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0023] like Figures 1-3As shown, this application provides a stamping sheet clamping and transporting device, including a frame 1, which is the outer frame of the stamping sheet clamping and transporting device, mainly serving a supporting function to ensure the stability of the stamping sheet during clamping and transporting. Universal wheels 4 are fixedly installed at the four corners of the bottom of the frame 1, facilitating the movement of the frame 1 and making the stamping sheet clamping and transporting device more convenient to use. The universal wheels 4 improve the mobility of the stamping sheet clamping and transporting device, reduce the labor intensity of manual handling, and adapt to multi-station operation of stamping sheet transporting operations. A top plate 2 is fixedly installed on the top of the frame 1. The top plate 2 provides a certain degree of protection for the upper part of the frame 1. When an object falls from the top of the frame 1, the top plate 2 catches the object and prevents it from falling onto important components inside the frame 1, thus improving the safety of the stamping sheet clamping and transport equipment. A crossbar 22 is slidably installed at the bottom of the top plate 2, and a first cylinder 26 is fixedly installed at the bottom of the top plate 2. The output end of the first cylinder 26 is fixedly connected to the crossbar 22. When the first cylinder 26 is started, it is suitable to drive the crossbar 22 to slide at the bottom of the top plate 2. In order to make the sliding of the crossbar 22 more stable, a support bar 21 is fixedly installed at the upper end of one side of the frame 1. One side of the bottom of the crossbar 22 is slidably connected to the top of the support bar 21, so that the top and bottom of the crossbar 22 are supported, and the sliding of the crossbar 22 is more stable. Two sets of hangers 23 are slidably installed at the bottom of the crossbar 22. When subjected to external force, the hangers 23 are adapted to slide in the installation direction of the crossbar 22 to facilitate the subsequent transportation of the stamping sheet metal. The transportation method will be described below. A connector 24 is fixedly installed at the bottom of the hanger 23, and a horizontal tube 25 is fixedly installed at the bottom of the connector 24. The hangers 23, connectors 24, and horizontal tube 25 are all part of the clamp structure. A slide rail (not shown in the figure) is slidably installed at the bottom of the horizontal tube 25. A drive cylinder is provided on one side of the slide rail. The output end of the drive cylinder is connected to the slide rail. The fixed connection allows the slide rail to move at the bottom of the horizontal tube 25 after the drive cylinder is started. An upper clamping unit is fixedly installed at the bottom of the slide rail. At the same time, an upper clamping unit is also installed on the side of the bottom of the horizontal tube 25 away from the drive cylinder. It can be understood that in the initial state, the upper clamping units are located on both sides of the horizontal tube 25, with one side of the upper clamping unit being fixed and the other side of the upper clamping unit being connected to the drive cylinder. When the drive cylinder is started, it is suitable to move the upper clamping unit on that side toward the upper clamping unit on the other side, so as to facilitate the subsequent clamping and positioning of the stamping sheet. The upper clamping unit includes a vertical tube 3, one side of which is fixedly installed at the bottom of the horizontal tube 25, while the other side is fixedly installed at the bottom of the slide rail. A second cylinder 31 is fixedly installed on the corresponding side of the vertical tube 3. A transition plate 32 is fixedly installed at the output end of the second cylinder 31, and an upper clamping plate 33 is fixedly installed at the bottom of the transition plate 32. In this application, both ends of the upper clamping plate 33 are fixedly connected to the bottoms of the transition plates 32 on both sides, so that when the upper clamping unit is used, the second cylinders 31 on both sides must be opened simultaneously to prevent the upper clamping plate 33 from shifting downwards on one side while remaining stationary on the other. To address the issue of damage caused by movement, when clamping the stamping sheet, the bottom of the upper clamping plate 33 contacts the bottom of the stamping sheet, achieving a clamping effect on the entire surface of the stamping sheet. Compared to traditional clamps that only clamp the two sides of the stamping sheet, the integrated upper clamping plate 33 in this application can apply more comprehensive downward pressure to the stamping sheet, thereby achieving a better clamping effect. At the same time, the integrated upper clamping plate 33 can make the stamping sheet more evenly compressed during clamping and transportation, resulting in a more uniform pressure distribution on the stamping sheet and avoiding the risk of uneven stress and warping of the stamping sheet during clamping and transportation. like Figure 3 As shown, at least two sets of upper suction cups 34 are installed at the bottom of the upper clamping plate 33. When clamping the stamping sheet, the upper suction cups 34 play an auxiliary role in suctioning the upper end of the stamping sheet. Especially when the stamping sheet is thin and the middle part is prone to denting, the suction cups can assist in suctioning the middle part of the stamping sheet to avoid the middle part denting. In this application, the upper suction cups 34 are made of silicone. When the stamping sheet is attached to the upper suction cups 34, it will not cause scratches to the surface of the stamping sheet. like Figures 2-5 As shown, a lower clamping unit is fixedly installed at the bottom of the upper vertical tube 3 on both sides. The lower clamping unit includes a connecting tube 7 fixedly installed at the bottom of the vertical tube 3. A side plate 71 is fixedly installed on the corresponding side of the connecting tube 7. An adjusting plate 72 is fixedly installed on both sides of the corresponding side of the side plate 71. At the same time, a vertical sliding groove is opened on the corresponding side of the side plate 71. A slider is slidably installed in the sliding groove. A lower clamping plate 74 is fixedly installed on one side of the slider. If the lower clamping plate 74 is not subjected to external force, it will fall naturally due to gravity. At this time, the slider is located at the bottom of the sliding groove. At this time, the lower clamping plate 74 is farthest from the upper clamping plate 33. When clamping the stamping plate, the thickest stamping plate within the maximum limitation range can be clamped. However, during the clamping of stamping sheets, it is often necessary to clamp stamping sheets of different thicknesses. Therefore, the height of the lower clamping plate 74 needs to be adjusted. A support plate 75 is provided at the bottom of the lower clamping plate 74. Normally, the lower clamping plate 74 rests on the support plate 75, which supports it. Thus, when clamping the stamping sheet, the bottom of the sheet is supported by both the lower clamping plate 74 and the support plate 75. This allows the stamping sheet clamping and conveying equipment to handle heavier stamping sheets. (Continue to refer to...) Figure 4 Adjusting blocks 78 are fixedly installed on both sides of the support plate 75. At the same time, at least two sets of adjusting grooves 73 are opened on one side of the adjusting plate 72. One side of the adjusting block 78 is adapted to one side of the adjusting groove 73 and is suitable for insertion into the adjusting groove 73. When one side of the adjusting block 78 is inserted into the adjusting groove 73, the adjusting block 78 is restricted by the adjusting groove 73. At the same time, both sides of the support plate 75 are restricted. At this time, the lower clamping plate 74 cannot slide up or down, thereby limiting the support plate 75 and enabling the lower clamping plate 74 to be better supported. Furthermore, when clamping heavier stamping sheets, the lower clamping plate 74 and the support plate 75 need to withstand greater pressure. (Continue to refer to...) Figure 4 At least two sets of adjusting bolts 76 are threaded on one side of the support plate 75, and multiple sets of adjusting holes 77 are opened on the side plate 71. One end of the adjusting bolt 76 is suitable for insertion into the adjusting hole 77. Therefore, when clamping the stamping sheet, the multiple sets of adjusting bolts 76 play a role in segmented support for the support plate 75, further improving the pressure bearing capacity of the support plate 75. In this application, the coordinated use of the adjusting block 78 and the adjusting groove 73 enables free adjustment of the vertical height of the lower clamping plate 74, thereby adapting to the clamping of plates of different thicknesses and solving the limitation of traditional fixed clamps that can only handle stamping plates of a single thickness. At the same time, an adjusting bolt 76 is also provided to provide segmented support for different positions of the support plate 75, so that the support plate 75 can bear the pressure of heavier stamping plates. Furthermore, the adjusting bolt 76 can be made of high-strength alloy steel and locked with threads to reduce the vibration and movement of the stamping plates during clamping and transportation, ensuring that the stamping plate clamping and transportation equipment can be used for a long time. A soft pad 79 is also fixedly installed on the top of the lower clamping plate 74. When the stamping plate is clamped, the two sides of the bottom of the stamping plate come into contact with the soft pad 79. The soft pad 79 provides flexible support to the two sides of the bottom of the stamping plate, while avoiding direct contact between the stamping plate and the lower clamping plate 74, thus avoiding wear of the stamping plate and easy damage to the lower clamping plate 74. When clamping the stamped sheet, the operator first needs to use tools to move the stamped sheet between the lower clamping plate 74 and the upper clamping plate 33. Then, the bottom of one side of the stamped sheet is placed on the lower clamping plate 74 on one side. Then, the operator starts the drive cylinder. The opening of the drive cylinder drives the upper clamping unit on one side to move until the lower clamping plate 74 on that side reaches the bottom of the other side of the stamped sheet. Then, the entire pressure plate can be placed. At this time, the positioning of the stamped sheet is completed. The two sides of the bottom of the stamped sheet are placed on the soft pads 79 of the lower clamping plate 74, and the bottom of the stamped sheet is supported. Then the staff opened the second cylinder 31. The second cylinder 31 started and moved the upper clamping plate 33 down. The upper clamping plate 33 continued to move down under the action of the second cylinder 31 until it was in contact with the top of the stamping plate. When it was in contact, the upper suction cup 34 played an auxiliary role in holding the top of the stamping plate, while the upper clamping plate 33 and the lower clamping plate 74 clamped the top and bottom of the stamping plate. It should be noted that in this application, the crossbar 22 is relatively long (not shown in the figure), and the hanger 23 is adapted to slide on the crossbar 22 when subjected to external force. This is to facilitate the transport of the clamped stamped sheet metal. Figure 2 As shown, no support bar 21 or other components are installed on one side of the frame 1. The purpose of this is to facilitate the movement of the upper and lower clamping units by the hanging part 23 during the movement process without being obstructed. The movement of the hanging part 23 can be achieved by a cylinder or other driving components, which will not be described in detail here. To clamp different stamped sheet metals, firstly, the adjusting bolt 76 needs to be removed, and then the adjusting block 78 needs to be pulled out from the adjusting groove 73 to separate the support plate 75 from the lower clamping plate 74. Then, the lower clamping plate 74 can be moved up or down arbitrarily to adjust its horizontal height. After adjustment, the worker inserts the adjusting block 78 into the adjusting groove 73, and then installs the adjusting bolt 76 in sequence. This achieves the adjustment of the horizontal height of the lower clamping plate 74, thereby adjusting the distance between the lower clamping plate 74 and the upper clamping plate 33 to accommodate the clamping of stamped sheet metals of different thicknesses. It should be added that, in this application, soft pads 79 are also installed on both sides of the bottom of the upper clamping plate 33. The purpose is to prevent the top sides of the stamping plate from directly contacting the bottom sides of the upper clamping plate 33 when clamping the stamping plate. This protects both the stamping plate and the upper clamping plate 33. The soft pads 79 allow for a slight change in the distance between the upper clamping plate 33 and the lower clamping plate 74. When there is a small error in the thickness of the stamping plate, there is no need to adjust the horizontal height of the lower clamping plate 74. The soft pads 79 adapt to the distance between the clamping plate and the stamping plate, thus achieving the same clamping effect on the stamping plate. like Figure 1 , Figures 6-7As shown, a lifting assembly is provided at the bottom of the frame 1. The lifting assembly includes a base plate 5 fixedly installed at the bottom of the frame 1. A lifting groove 52 is provided at the top of the base plate 5. A lifting slider is slidably installed in the lifting groove 52. A sliding plate 51 is fixedly installed at the top of the lifting slider. A lifting cylinder 55 is fixedly installed at the top of the sliding plate 51. A lifting plate 53 is fixedly installed at the output end of the lifting cylinder 55. It should be noted that the setting direction of the lifting groove 52 is the same as the installation direction of the crossbar 22. When clamping and conveying the stamped sheet metal, the operator can place the stamped sheet metal on the lifting plate 53, and then start the lifting cylinder 55. The start of the lifting cylinder 55 drives the lifting plate 53 to move upward, and the lifting plate 53 moves upward to move the stamped sheet metal above the lower clamping plate 74. At this time, the drive cylinder is started to clamp the stamped sheet metal. The lifting component plays the role of lifting and facilitating the clamping of the stamped sheet metal. If the stamped sheet is heavy, it is inevitable that instability will occur if the stamped sheet is supported only by the lifting cylinder 55 and the lifting plate 53. Therefore, buffer components 6 are fixedly installed at the four corners of the top of the slide plate 51. The buffer components 6 include an outer cylinder 61 fixedly installed on the slide plate 51. The interior of the outer cylinder 61 is hollow. An inner cylinder 62 is set inside the outer cylinder 61. The top of the inner cylinder 62 is fixedly connected to the top of the lifting plate 53. A spring 63 is fixedly installed at the bottom of the inner cylinder 62. In the initial state, the spring 63 is in a compressed state. During the lifting process, the lifting cylinder 55 is activated, and the spring 63 gradually recovers due to the rise of the lifting plate 53, which plays an auxiliary supporting role for the four corners of the lifting plate 53. The spring 63 can absorb the downward pressure of the stamped sheet so that the lifting plate 53 can adapt to the lifting of heavy stamped sheets. Furthermore, at least two sets of lower suction cups 54 are fixedly installed on the lifting plate 53. The suction force of the lower suction cups 54 is less than that of the upper suction cups 34. When the stamping plate is placed on the lifting plate 53, the lower suction cups 54 play an auxiliary role in suctioning the middle of the stamping plate. Especially when clamping a thin stamping plate, the lower suction cups 54 can assist in lifting the bottom of the stamping plate to prevent it from sinking in the middle during clamping. If the lower suction cups 54 are attached to the stamping plate, due to the large friction between them, a certain amount of external force is required to separate the stamping plate from the lower suction cups 54. During the transportation of the stamped sheet, when the hanger 23 moves, it drives the upper clamping unit and the lower clamping unit to move synchronously. The synchronous movement of the upper clamping unit and the lower clamping unit drives the stamped sheet to move. Since the stamped sheet is held by the lower suction cup 54, there is a large friction between the two. As the stamped sheet is in a moving state, the stamped sheet will drive the lower suction cup 54 to move synchronously, the lifting plate 53 to move synchronously, and the slide plate 51 to slide on the base plate 5. During the movement, the stamped sheet will still be supported by the lower suction cup 54, which prevents the middle from denting during transportation, further improving the transportation quality of the stamped sheet clamping and transportation equipment. In this application, since the horizontal height of the lower clamping plate 74 is variable, the lifting height of the lifting plate 53 should change accordingly. For this purpose, a flexible pad is fixedly installed on the lifting plate 53. The flexible pad is relatively thick. During the lifting process, the horizontal height of the top of the lifting plate 53 will not exceed the horizontal height of the top of the lower clamping plate 74, while the horizontal height of the top of the flexible pad will always exceed the horizontal height of the top of the lower clamping plate 74. Therefore, when the upper clamping plate 33 clamps the stamping plate during the downward movement, the flexible pad will always be squeezed and compressed to adapt to the different position heights of the lower clamping plate 74. It should be added that, in this application, a coating is added to the surface of both the soft pad 79 and the flexible pad, which further prevents the stamped sheet from slipping on the upper and lower clamping units, effectively reducing the problem of product damage caused by the stamped sheet slipping and improving the safety of the stamped sheet clamping and transport equipment. Secondly, after the lifting component leaves with the previous set of stamped sheet metal, it cannot automatically return to its initial position to facilitate the clamping and transportation of the next set of stamped sheet metal. Therefore, the operator can install a cylinder or other driving device on one side of the lifting component to help it reset. In order to facilitate the periodic activation of this command, a PLC control system can be set up. When a set of clamping and transportation operations is completed, the cylinder on one side of the lifting component will be activated to drive it to reset, so as to facilitate the clamping and transportation of subsequent stamped sheet metal. In summary, this application, by providing an adjustable lower clamping plate 74, facilitates the clamping of stamping sheets of different thicknesses by the upper and lower clamping units. Furthermore, the lower clamping plate 74 and the support plate 75 provide dual support for the stamping sheet, ensuring that the stamping sheet clamping and transport equipment can adapt to and support heavier stamping sheets. Additionally, an upper suction cup 34 is provided to assist in clamping the middle of the top of the stamping sheet, preventing the problem of deformation caused by the middle of the stamping sheet not being clamped. Furthermore, by installing soft pads 79 on both the upper and lower clamping units, the problem of friction damage between the two sides of the stamped sheet and the clamp can be avoided during the clamping process, thus protecting both the stamped sheet clamping and transport equipment and the stamped sheet. Furthermore, a lifting component is also provided. During the clamping and conveying process, the lifting component lifts the stamped sheet, and the lower suction cup 54 plays an auxiliary lifting role on the middle of the bottom of the stamped sheet, preventing deformation of the thin stamped sheet. Finally, a lifting chute 52 is also provided. When the stamped sheet is being conveyed, due to the friction between the lower suction cup 54 and the stamped sheet, the stamped sheet moves and drives the lower suction cup 54 to move synchronously. The lifting component can continuously lift the sheet being conveyed, preventing deformation of the stamped sheet during the conveying process, and further improving the conveying quality of the stamped sheet clamping and conveying equipment.
