Description

Technical Field

[0001] This utility model relates to the field of automotive sheet metal processing, specifically a suction cup mechanism for laser welding and unloading automotive sheet metal. Background Technology

[0002] Laser welding is a crucial process in automotive sheet metal processing. With technological advancements, some automated sheet metal laser welding unloading devices have emerged. For example, patent CN218988081U discloses a product unloading device for a laser production line, including an unloading robot with a transfer fixture mounted on its execution end. The suction cup assembly on the transfer fixture can slide along a first or second mounting rail, aligning and adsorbing the product without requiring replacement or disassembly of the transfer fixture. However, with the development of the automotive industry, the shapes and specifications of automotive sheet metal after laser welding are becoming increasingly diverse. Existing suction cup assembly structures are mostly traditional rectangular or square matrix layouts. Even with adjustable suction cup positions, as in patent CN218988081U, the adjusted suction cup layout remains approximately rectangular or square, which is practically insufficient for adsorbing irregularly shaped sheet metal. Utility Model Content

[0003] The purpose of this invention is to provide a suction cup mechanism for laser welding and blanking of automotive sheet metal. The suction cup layout of each suction cup assembly can be flexibly adjusted according to the shape of the sheet metal, and it is especially suitable for adsorption and transfer of irregularly shaped sheet metal.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A suction cup mechanism for laser welding blanking of automotive sheet metal includes a slot beam and multiple suction cup assemblies. The suction cup assembly includes a suction cup frame, a locking block, a suction cup adjusting block, a locking block adjusting block, and a suction cup. The locking block adjusting block and the suction cup adjusting block are adjustablely disposed in the suction cup frame, and the locking block is installed on the corresponding locking block adjusting block, and the suction cup is installed on the corresponding suction cup adjusting block. The locking block is provided with a locking protrusion that mates with the locking groove on the corresponding side of the slot beam.

[0006] The suction cup frame is provided with an adjustment slot. The two sides of the adjustment block are fixed to the suction cup frame by the adjustment block fastening bolts, and the adjustment block fastening bolts pass through the corresponding adjustment slots.

[0007] The locking block is fixed to the corresponding locking block adjusting block by locking block mounting bolts, and the locking block mounting bolts are perpendicular to the axis of the locking block fastening bolts.

[0008] The suction cup frame is provided with multiple sets of adjustment screw holes. The suction cup adjustment block is fixed to the suction cup frame by suction cup fastening bolts, and the suction cup fastening bolts pass through the corresponding set of adjustment screw holes.

Detailed Implementation

[0017] The present invention will now be described in further detail with reference to the accompanying drawings.

[0018] like Figures 1-5 As shown, this utility model includes a slot beam 202 and multiple sets of suction cup assemblies 1, wherein... Figures 1-2As shown, the suction cup assembly 1 includes a suction cup frame 102, a locking block 101, a suction cup adjusting block 105, a locking block adjusting block 108, and a suction cup 106. Both the locking block adjusting block 108 and the suction cup adjusting block 105 are adjustablely disposed within the suction cup frame 102. The locking block 101 is mounted on the corresponding locking block adjusting block 108, and the suction cup 106 is mounted on the corresponding suction cup adjusting block 105. The locking block 101 has a locking protrusion 1011 that mates with the corresponding side slot of the slot beam 202. In use, after the operator moves the locking blocks 108 outwards, the locking blocks 101 no longer clamp the slot beam 202. At this time, the entire suction cup frame 102 can be adjusted along the length of the slot beam 202. Once the position of the suction cup assembly 1 is determined, the locking block adjusting block 108 is moved again to re-clamp and fix the locking block 101 onto the slot beam 202. This invention also allows for adjustment of the position of each suction cup 106 on the suction cup holder 102 according to actual needs. For example... Figure 5 As shown, the shape of the sheet metal workpiece 10 after laser welding is often quite unique, and it is mostly an irregularly shaped workpiece. The traditional rectangular or square matrix suction cup layout in the existing technology often cannot be well matched with the workpiece for adsorption and pickup. However, the present invention can adjust the position of the suction cup frame 102 and the position of the suction cup 106 so that the layout of the suction cup 106 on the suction cup assembly 1 can better match the shape of the sheet metal workpiece 10, making it more flexible and greatly improving its applicability.

[0019] like Figure 1 As shown, in this embodiment, the suction cup frame 102 is provided with an adjustment slot 1021. The two sides of the locking block adjustment block 108 are fixed to the suction cup frame 102 by locking block fastening bolts 104, and the locking block fastening bolts 104 pass through the corresponding adjustment slot 1021. After the operator loosens the locking block fastening bolts 104 outward, the locking block adjustment block 108 can move and adjust within the suction cup frame 102, and its adjustment range is the length range of the adjustment slot 1021. Figure 1 As shown, when the two adjusting blocks 108 move outward, the two locking blocks 101 release the locking beam 202; when the two adjusting blocks 108 move inward, the two locking blocks 101 clamp the locking beam 202. Additionally, as... Figures 1-2 As shown, in this embodiment, the locking block 101 is fixed to the corresponding locking block adjusting block 108 by the locking block mounting bolt 103, and the locking block mounting bolt 103 is axially perpendicular to the locking block fastening bolt 104.

[0020] like Figures 1-2As shown, in this embodiment, the suction cup frame 102 is provided with multiple sets of adjusting screw holes 1022. The suction cup adjusting block 105 is fixed to the suction cup frame 102 by suction cup fastening bolts 107, and the suction cup fastening bolts 107 pass through a corresponding set of adjusting screw holes 1022. The design of each set of adjusting screw holes 1022 realizes the position adjustment of the suction cup adjusting block 105, and the specific position and number of each set of adjusting screw holes 1022 are designed according to actual needs. In addition, since the suction cup frame 102 is usually long, and this utility model only uses a single beam support of the slot beam 202, in order to ensure the support strength of the suction cup frame 102, this embodiment adopts a structure of multiple sets of adjusting screw holes 1022 to realize the position adjustment of the suction cup adjusting block 105.

[0021] The working principle of this utility model is as follows:

[0022] When using this invention, after the operator moves the adjusting blocks 108 on both sides outward, the locking blocks 101 on both sides no longer clamp the slot beam 202. At this time, the entire suction cup frame 102 can be adjusted along the length of the slot beam 202. After the position of the suction cup assembly 1 is determined, the adjusting blocks 108 are moved again to make the locking blocks 101 re-clamp and fix on the slot beam 202. In addition, this invention can also adjust the position of each suction cup 106 on the suction cup frame 102 according to actual needs. Therefore, this invention can adjust the position of the suction cup frame 102 and the position of the suction cups 106 to make the layout of the suction cups 106 on the suction cup assembly 1 better match the shape of the sheet metal workpiece 10, making it more flexible and greatly improving its applicability. It is especially suitable for... Figure 5 The irregularly shaped sheet metal workpiece 10 shown is adsorbed.

[0023] like Figures 3-4 As shown, in one application example of this utility model, the slot beam 202 is driven to rise and fall by the cooperation of the upper cylinder 7 and the lower cylinder 6, thereby driving the lifting and lowering of each set of suction cup assemblies 1 to realize the transfer of the sheet metal workpiece 10. This application example includes a moving frame 5, a lifting seat 2, an upper cylinder 7, a lower cylinder 6, a transition plate 4, and a connecting rod 3, wherein, as shown... Figure 4 As shown, two lifting seats 2 are respectively located on both sides of the movable frame 5, and the lower ends of both lifting seats 2 are fixedly connected to the slot beam 202. The movable frame 5 is provided with a drive shaft 504, and both ends of the drive shaft 504 are provided with adapter plates 4, as shown. Figure 3As shown, the lower end of the adapter plate 4 is hinged to the upper end of the connecting rod 3 on the corresponding side, and the lower end of the connecting rod 3 is hinged to the upper end of the lifting seat 2 on the corresponding side. The upper and lower parts of the moving frame 5 are each provided with a mounting seat 8. The cylinder bodies of the upper cylinder 7 and the lower cylinder 6 are respectively hinged to the corresponding mounting seats 8. The output shafts of the upper cylinder 7 and the lower cylinder 6 are both hinged to the adapter plate 4 on the corresponding side. In this application example, the upper cylinder 7 and the lower cylinder 6 cooperate to extend and retract, driving the adapter plate 4 to rotate. The rotation of the adapter plate 4 drives the lifting seat 2 to move up and down via the connecting rod 3, which in turn drives the slot beam 202 to move each set of suction cup assemblies 1 up and down. When the plate workpiece 10 is welded, the moving frame 5 moves above the plate workpiece 10, and then the suction cup assembly 1 descends to adsorb the plate workpiece 10. The moving frame 5 then moves the plate workpiece 10 to the next workstation. The driving mechanism of the movable frame 5 is a technology known in the art. For example, it can adopt the X-axis moving mechanism in patent CN110877826B, or other suitable structures.

[0024] Other examples Figure 3 As shown in this application example, the lower side of the lifting seat 2 is provided with a connecting plate 201, and the connecting plate 201 is fixedly connected to the slot beam 202 by bolts. In addition, the movable frame 5 is provided with a slide rail 501, and the lifting seat 2 is provided with a slider 203 that cooperates with the slide rail 501 to achieve a sliding connection with the movable frame 5, while also ensuring that the lifting seat 2 can be raised and lowered vertically. The movable frame 5 is provided with a transition seat 502, and both ends of the drive shaft 504 are respectively supported and mounted on the corresponding transition seats 502 by bearings. The middle part of the transition plate 4 is fixedly connected to the corresponding end of the drive shaft 504. The transition plates 4 on both sides of the movable frame 5 are driven to rotate synchronously by the drive shaft 504, thereby ensuring that the slot beam 202 remains horizontal during the raising and lowering action.
