[0028] To solve the technical problems in the background art, as shown in the Figures 1-4 The present application provides a technical solution: a metal sheet welding auxiliary suction and turnover device, characterized by:

[0029] The fixed seat 1 is a rectangular frame structure, and the upper end face is provided with an opening for placing the material box 2. The material box 2 is arranged in the fixed seat 1 and is used for storing the metal sheets to be welded. The mounting plate 3 is a U-shaped structure and is arranged on the fixed seat 1. The side walls of the mounting plate 3 are provided with guide rails 4 on both sides, and the middle part is provided with a through slot 5, and the upper part is provided with a bearing seat 6. The bearing seat 6 is provided with a transmission shaft 7, and one end of the transmission shaft 7 is connected with a driving hand wheel 8. The two sides of the sliding plate 9 are slidably connected with the guide rails 4, so as to ensure that the sliding plate 9 can slide up and down along the guide rails 4. The middle of the sliding plate 9 is provided with a bearing support 10, and the bearing support 10 is provided with a rotating shaft 11. One end of the rotating shaft 11 is connected with a suction cup 12, and the other end penetrates through the through slot 5 and is connected with a connecting plate 13. The other end of the connecting plate 13 is provided with a follower 14. A rotating disc 15 is arranged at one end of the transmission shaft 7, and the periphery of the rotating disc 15 is connected with a connecting rod 16. The other end of the connecting rod 16 is connected with the sliding plate 9. The hand wheel 8 drives the rotating disc 15 to rotate, and drives the sliding plate 9 to slide up and down through the connecting rod 16. A steering plate 17 is arranged on the fixed seat 1, and the steering plate 17 is provided with a cam groove 18 for accommodating the follower 14. The two ends of the cam groove 18 are straight grooves, and the middle part is provided with a 180-degree arc-shaped bending part. The straight groove part of the cam groove 18 is arranged vertically, and the vertical plane where the straight groove part is located is coplanar with the plane where the rotating shaft 11 slides up and down. When the sliding plate 9 drives the rotating shaft 11 to slide up and down, the cam groove 18 realizes 180-degree steering of the suction cup 12.

[0030] When in use, the metal sheet to be welded is placed in the trough of the material box 2. The rotating disc 15 is driven to rotate by the hand wheel 8, and the rotating disc 15 drives the sliding plate 9 to move downward through the connecting rod 16. The sliding plate 9 drives the rotating shaft 11 to move downward, so that the suction disc 12 contacts the metal sheet in the material box 2. The suction disc 12 generates suction force through the vacuum generator, and firmly adsorbs the metal sheet. After the suction disc 12 adsorbs the metal sheet, the rotating disc 15 is driven to rotate reversely by the hand wheel 8, the rotating disc 15 drives the sliding plate 9 to move upward through the connecting rod 16. The sliding plate 9 drives the rotating shaft 11 to move upward, and the follower 14 moves along the cam groove 18. The 180-degree arc-shaped bending part of the cam groove 18 drives the rotating shaft 11 to rotate 180 degrees through the follower 14, so that the metal sheet is turned over. After the metal sheet is turned over to the required angle, welding work is performed. After the welding is completed, the suction disc 12 releases the vacuum suction force, and the welded metal sheet is taken out. The rotating disc 15 is continuously driven to rotate by the hand wheel 8, so that the sliding plate 9 drives the rotating shaft 11 to move downward, and returns to the initial position to prepare for the next auxiliary suction and turning over.

[0031] It should be noted that the bottom of the material box 2 is provided with a spring 19, and the spring 19 is used to provide upward elastic force to the metal sheet. A mounting hole is arranged at the central position of the bottom of the material box 2, and the spring 19 is mounted in the mounting hole. The spring 19 is a cylindrical compression spring, and is made of high-elasticity stainless steel, which has good elasticity and corrosion resistance. One end of the spring 19 is fixed in the mounting hole, and the other end is freely supported on the bottom of the material box 2. The arrangement of the spring 19 ensures that the metal sheet always maintains upward pressure in the material box 2, which facilitates the suction of the metal sheet by the suction disc 12. The elastic force of the spring 19 can be adjusted according to the weight and size of the metal sheet, so that the metal sheet can be smoothly sucked up.

[0032] Further, the cam groove 18 has straight grooves at both ends and a 180-degree arc-shaped bending part in the middle. The straight groove part is arranged vertically, and the connection part between the bending part and the straight groove is treated with a round corner, so that the follower 14 can smoothly transition during movement, reducing friction and mechanical impact. The round corner treatment can effectively reduce the friction force of the follower 14 when entering and leaving the bending part, improve the smoothness and reliability of the movement, reduce mechanical impact, prolong the service life of the device, and reduce maintenance costs.

[0033] It should be noted that the bending part of the cam groove 18 is chamfered, and the main purpose is to remove the sharp edges of the bending part of the cam groove 18. The chamfering of the bending part of the cam groove 18 can effectively disperse stress and prevent cracks caused by stress concentration.

[0034] It should be noted that the suction cup 12 is driven by vacuum, connected to a vacuum generator through an air pipe. The vacuum generator is installed outside the fixed base 1, providing a stable vacuum source. The suction cup 12 is connected to the vacuum generator through the air pipe. The material of the air pipe should be selected to be pressure-resistant and wear-resistant, such as polyurethane or nylon pipe. The inner diameter of the air pipe should be selected according to the flow rate of the vacuum generator and the size of the suction cup 12, to ensure that the vacuum pressure can be effectively transmitted.

[0035] It is worth noting that the hand wheel 8 is a circular structure, and the handle 20 is fixedly installed at the outer edge of the hand wheel 8, in a cylindrical or elliptical cylindrical shape, with anti-slip patterns 21 designed on the surface to increase friction and ensure stability during operation. The anti-slip patterns 21 can be grooves, protrusions, grid patterns, or any other texture that can effectively increase friction. These anti-slip patterns 21 not only improve the comfort of holding the handle 20, but also significantly enhance the gripping force of the operator when manually driving the turntable 15, thereby improving the accuracy and safety of operation.

[0036] It should be noted that the center axis of the material box 2 is aligned with the center axis of the rotating shaft 11 in the vertical direction. This design ensures that the suction cup 12 can accurately align the metal sheet in the material box 2 during the lowering process, improving the accuracy and reliability of the suction. The opening direction of the material box 2 is consistent with the suction direction of the suction cup 12. This means that when the suction cup 12 is lowered, its suction surface can directly align with the metal sheet in the material box 2 without the need for additional adjustment, ensuring smooth and efficient suction process.

[0037] It should be noted that the cam groove 18 is completely located within the horizontal projection range of the through groove 5. This means that the projection of the cam groove 18 in the horizontal direction is completely covered by the through groove 5, ensuring that the follower 14 always contacts the cam groove 18 during the sliding process of the sliding plate 9, without being interfered by the through groove 5.

[0038] Although embodiments of the present application have been shown and described, it will be understood by those of ordinary skill in the art that various changes, modifications, substitutions and alterations can be made without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
