Description

[0002] The structural design of metal shelves is flexible and diverse, and can be combined, adjusted and customized according to actual needs, such as changing the height, length, number of layers, etc. of the shelves to adapt to different space layouts and cargo storage requirements.

[0003] Metal shelves are composed of columns, beams, shelves, connectors, etc. However, when assembling the beams and columns, it is often necessary to weld the mounting plate and the beams first, and then connect the holes of the mounting plate with the holes of the columns and fix them with bolts. When welding the existing mounting plates and beams, it is often necessary to manually lift the beams onto the welding fixture and then use an automatic welding gun to weld them. This method can only weld one beam at a time. If you want to weld beams in batches, you need to lift multiple beams onto the welding fixture. In order to facilitate welding, each beam needs to maintain a certain height, which requires manual lifting to different heights for placement and fixation. On the one hand, this method requires a lot of physical strength of the staff. On the other hand, it is impossible to fix multiple beams at the same time, which reduces work efficiency.

DETAILED DESCRIPTION

[0030] In order to make the objectives, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0031] In one embodiment, Figure 1-Figure 7 As shown, a metal shelf combination processing device includes a multi-layer movable welding gun 1, a driver 2, a movable plate 3, a conveyor frame 4, a first guide rail 15, a first positioning assembly, and a second positioning assembly. A conveyor belt 5 is provided between the two conveyor frames 4. The side walls of the conveyor belt 5 are fixedly connected to a plurality of first placement racks 6 for placing shelf beams. The first placement racks 6 are "L"-shaped. The inner side walls of the two first guide rails 15 are slidably connected to the movable plates 3. The side walls of the movable plates 3 are fixedly connected to a plurality of second placement racks 14 for placing mounting plates. The positions of the plurality of second placement racks 14 correspond one-to-one to the plurality of first placement racks 6. The multi-layer movable welding gun 1 is used to weld the beams and the mounting plates. The driver 2 is used to drive the movable plate 3 to move along the first guide rail 15.

[0032] The first positioning assembly is provided on the side wall of the movable plate 3 and is used to fix the shelf beam;

[0033] The second positioning assembly is arranged on the side wall of the movable plate 3 and is used to fix the mounting plate.

[0034] The multi-layer movable welding gun 1 is started and moved close to the fixed points of multiple beams and mounting plates to perform welding simultaneously, which greatly improves the welding combination efficiency of the beams and mounting plates;

[0035] The conveyor belt 5 is started intermittently, and the conveyor belt 5 drives the first placement racks 6 to move. The staff can stand in one place and carry the beams to the first placement rack 6 at the lowest point in turn. The conveyor belt 5 then rotates and transports them to the upper part. It does not require manual labor to use greater strength to carry the beams to a higher place, which is not only more labor-saving but also safer.

[0036] Several mounting plates are manually placed on the second placement rack 14 and are limited in position by the limiting blocks 13 .

[0037] In one embodiment, the first positioning assembly includes a slider 19 and a fixed block 25. The side wall of the movable plate 3 is provided with a plurality of slider holes. The slider 19 is slidably connected to the inner side wall of the slider hole. The fixed block 25 is fixedly connected to the side wall of the slider 19. The fixed block 25 is threadedly connected to the first adjusting bolt 27. The lower surface of the first adjusting bolt 27 is connected to the first movable plate 28 through a bearing. The first movable plate 28 and the fixed block 25 are slidably connected to a guide rod 26, and the guide rod 26 is fixedly connected to the first movable plate 28.

[0038] The side walls of several sliders 19 are commonly fixedly connected to the second rack 20, the side walls of the movable plate 3 are rotatably connected to several gears 23 through the rotating shaft, the side walls of the movable plate 3 are fixedly connected to the second guide rail 21, the inner side walls of the second guide rail 21 are slidably connected to several slide rods 24, and the several slide rods 24 are commonly fixedly connected to the first rack 18. The second rack 20 and the first rack 18 are both engaged with several gears 23. The upper surface of the first guide rail 15 is fixedly connected to the second convex plate 17, and the upper surface of the second convex plate 17 is provided with a trapezoidal block. The lower surface of the first rack 18 is provided with a second roller 22, and the second roller 22 abuts against the second convex plate 17.

[0039] When the movable plate 3 moves to a position close to the conveying rack 4, the first rack 18 is lifted up by the joint action of the second roller 22 and the trapezoidal block of the second protruding plate 17. At this time, the first rack 18 drives the gear 23 to rotate, and the gear 23 drives the second rack 20 to move downward. The weight of the first rack 18 is heavier than the second rack 20 and all the first positioning components. The second rack 20 drives several sliders 19 to move downward, and several sliders 19 drive several fixed blocks 25, the first movable plate 28, and the longitudinal positioning plate 34 to move downward, completing the simultaneous fixation of several beams. There is no need to manually fix multiple beams, which is more efficient.

[0040] In one embodiment, the lower surface of the first movable plate 28 is connected to a longitudinal positioning plate 34 via a plurality of second lifting and retracting rods 35 , and a spring is fixedly connected between the longitudinal positioning plate 34 and the first movable plate 28 .

[0041] The longitudinal positioning plate 34 cooperates with the spring to provide buffering.

[0042] In one embodiment, the side wall of the first moving plate 28 is slidably connected through the second moving plate 29. The second moving plate 29 is L-shaped. A transverse positioning plate 31 is provided on the side wall of the second moving plate 29. A second adjusting bolt 30 is threadedly connected to the side wall of the second moving plate 29. The second adjusting bolt 30 is fixedly connected to the transverse positioning plate 31. A connecting rod 36 is rotatably connected to the side wall of the longitudinal positioning plate 34 through a pin shaft. One end of the connecting rod 36 away from the longitudinal positioning plate 34 is rotatably connected to the second moving plate 29 through a pin shaft.

[0043] When the longitudinal positioning plate 34 descends and contacts the cross beam, when the first moving plate 28 continues to descend, the second telescopic rod 35 will contract, and the relative displacement between the first moving plate 28 and the longitudinal positioning plate 34 becomes smaller. The connecting rod 36 drives the second moving plate 29 to move into the first moving plate 28. The second moving plate 29 drives the transverse positioning plate 31 and the buffer plate 32 to approach the side wall of the cross beam, and limits and fixes the side wall of the cross beam. While longitudinally fixing the cross beam, its transverse direction is also fixed, improving the efficiency and effect of fixing the cross beam.

[0044] In one embodiment, a buffer plate 32 is connected to the side wall of the transverse positioning plate 31 through a first telescopic rod 33. A spring is fixedly connected between the buffer plate 32 and the transverse positioning plate 31.

[0045] The buffer plate 32 and the spring cooperate for buffering.

[0046] In one embodiment, the second positioning component includes a suction cup 12 and a limiting block 13. The second placement rack 14 is L-shaped. The limiting block 13 is installed on the second placement rack 14 through bolts. The suction cup 12 is installed on the side wall of the second placement rack 14. A plurality of suction cups 12 are commonly connected to an air pipe 11 through a pipeline. The air pipe 11 is fixedly connected to the side wall of the moving plate 3. A guide cylinder 8 is fixedly connected to the side wall of the moving plate 3. A piston rod 7 is slidably connected through the guide cylinder 8. The piston rod 7 is U-shaped. An air box 10 is fixedly connected to the side wall of the moving plate 3. One end of the piston rod 7 is provided with a piston. The piston end of the piston rod 7 is slidably connected to the inner side wall of the air box 10. The air box 10 is connected to the air pipe 11 through a pipeline. A first roller 9 is provided on the lower surface of the piston rod 7. A first convex block 16 is fixedly connected to the upper surface of the first guide rail 15. The first convex block 16 is provided with a convex inclined surface. The first roller 9 abuts against the first convex block 16.

[0047] When all the beams and mounting plates are in place, start the driver 2, which drives the movable plate 3 to move. During this process, when the first roller 9 moves to the inclined surface of the first protrusion 16, the piston rod 7 rises. The rising piston rod 7 drives the piston in the air box 10 to move, and air is extracted from the air holes of the suction cup 12. Since the mounting plate placed on the second placement rack 14 blocks the air holes of the suction cup 12, the suction cup 12 is deformed, firmly adsorbing the mounting plate to complete the fixation of the mounting plate, avoiding the movement of the mounting plate during the welding process, resulting in welding misalignment, and also avoiding the displacement of the mounting plate during the movement of the movable plate 3, so that the mounting plate and the beam can be accurately docked.

[0048] In one embodiment, the driver 2 , the movable plate 3 , the conveyor frame 4 , and the conveyor belt 5 are arranged at an angle.

[0049] The tilt setting can reduce the possibility of the mounting plate and beam falling to a certain extent.

[0050] The above embodiment discloses a metal shelf assembly processing device, and its specific working principle and process are as follows:

[0051] S1: The conveyor belt 5 is started intermittently, and the conveyor belt 5 drives the first placement racks 6 to move. The staff can stand in one place and carry the beams to the first placement rack 6 at the lowest point in sequence. The conveyor belt 5 then rotates and transports them to the upper position. There is no need for manual labor to use greater strength to carry the beams to a higher position, which is not only more labor-saving but also safer.

[0052] Several mounting plates are manually placed on the second placement rack 14 and are limited in position by the limiting blocks 13 .

[0053] S2: When all the beams and mounting plates are in place, the driver 2 is started, and the driver 2 drives the movable plate 3 to move. During this process, when the first roller 9 moves to the inclined surface of the first protrusion 16, the piston rod 7 rises, and the rising piston rod 7 drives the piston in the air box 10 to move, and air is extracted from the air holes of the suction cup 12. Since the mounting plate placed on the second placement rack 14 blocks the air holes of the suction cup 12, the suction cup 12 is deformed and firmly adsorbs the mounting plate, completing the fixation of the mounting plate, avoiding the movement of the mounting plate during the welding process, resulting in welding misalignment, and also avoiding the displacement of the mounting plate during the movement of the movable plate 3, so that the mounting plate and the beam are accurately docked;

[0054] S3: When the movable plate 3 moves to a position close to the conveying rack 4, the first rack 18 is lifted up by the joint action of the second roller 22 and the trapezoidal block of the second convex plate 17. At this time, the first rack 18 drives the gear 23 to rotate, and the gear 23 drives the second rack 20 to move downward. The weight of the first rack 18 is heavier than the second rack 20 and all the first positioning components. The second rack 20 drives the plurality of sliders 19 to move downward, and the plurality of sliders 19 drive the plurality of fixed blocks 25, the first movable plate 28, and the longitudinal positioning plate 34 to move downward, thereby completing the simultaneous fixation of the plurality of beams. There is no need to manually fix multiple beams, which is more efficient.

[0055] S4: When the longitudinal positioning plate 34 descends and contacts the crossbeam, the first movable plate 28 continues to descend, causing the second lifting and retracting rod 35 to contract, and the relative displacement between the first movable plate 28 and the longitudinal positioning plate 34 becomes smaller. The connecting rod 36 drives the second movable plate 29 to move into the first movable plate 28, and the second movable plate 29 drives the transverse positioning plate 31 and the buffer plate 32 to approach the side wall of the crossbeam, limiting and fixing the side wall of the crossbeam. While fixing the crossbeam longitudinally, it also fixes it transversely, thereby improving the efficiency and effect of fixing the crossbeam.

[0056] S5: Start the multi-layer movable welding gun 1, which is close to the fixed points of multiple beams and mounting plates to perform simultaneous welding, thereby greatly improving the welding efficiency of the beams and mounting plates;

[0057] Before welding, the first adjusting bolt 27 and the second adjusting bolt 30 can be adjusted so that the longitudinal positioning plate 34 and the buffer plate 32 are in appropriate positions, so that beams of different sizes can be fixed, thereby improving the applicability of the device.

[0058] The position of the limit block 13 can also be adjusted before welding, so that mounting plates of different sizes can be placed;

[0059] The relative position between the mounting plate and the crossbeam can be achieved by adjusting the height of the first placement rack 6 .

[0060] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of the present application. Therefore, the scope of protection of the present application should be based on the scope of protection of the claims.
