DETAILED DESCRIPTION

[0027] The specific implementation methods of the present invention are further explained in detail below by describing the embodiments with reference to the accompanying drawings, with the aim of helping those skilled in the art to have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitating their implementation.

[0028] like Figure 1 As shown, the battery pack shell flipping and fixing device includes a column 1, the column 1 is connected to a crossbeam 2, the crossbeam 2 is connected to a longitudinal rod 25, the bottom end of the longitudinal rod 25 is connected to a frame 4, and a fixing mechanism is provided below the frame 4. The column 1, the crossbeam 2 and the longitudinal rod 25 are used to support the frame 4 and realize its suspension. The battery pack shell is placed below the frame 4, and the battery pack shell is fixed by magnetic adsorption. It will not produce excessive clamping force on the battery pack shell, and effectively avoid damage to the battery pack shell. The column 1, the crossbeam 2 and the longitudinal rod 25 occupy a small space and are convenient to be arranged between different workstations. The crossbeam 2 is arranged horizontally, and the longitudinal rod 25 is perpendicular to the horizontal plane, so that the frame 4 is level as a whole. The longitudinal rod 25 is connected to the frame 4 by a flange 33, and both can be detachably installed.

[0029] like Figure 2-1 and Figure 2-2 As shown, the fixing mechanism includes an electromagnet 5, a guide rail 43 and a first cylinder 41 are provided at the bottom of the frame 4, a connecting plate 42 is provided below the frame 4, a slider 44 is fixedly connected to the upper end of the connecting plate 42, the slider 44 cooperates with the guide rail 43, and the piston rod of the first cylinder 41 is connected to the connecting plate 42; a gear 45 is rotatably connected to the middle of the bottom of the frame 4, a rack 46 is provided on the connecting plate 42, and the gear 45 meshes with the rack 46; a connecting rod 51 is provided at the bottom of the connecting plate 42, a bearing seat 54 is provided at the bottom of the connecting rod 51, a rotating shaft 53 is connected to the bearing seat 54, and the rotating shaft 53 is fixedly connected to the mounting plate 52, and the electromagnet 5 is provided at both ends of the mounting plate 52. The electromagnet 5 fixes the battery pack shell by adsorption, replacing the manual handling operation mode, and reducing the labor intensity of manual labor. A rotating shaft 53 is provided between the mounting plate 52 where the electromagnet 5 is located and the connecting rod 51 to realize the rotatable function of the mounting plate 52. After the battery pack shell is fixed, it can be manually flipped by humans, which is convenient for adjusting to a specified angle. In order to fix the battery pack shells of different sizes, the two connecting rods 51 are arranged relatively to each other, and the connecting plate 42 is driven by the first cylinder 41 to move along the guide rail 43. The spacing between the two connecting rods 51 is synchronously controlled through the meshing transmission of the gear 45 and the rack 46, that is, the lateral distance of the electromagnet 5 is adjusted. The connecting rod 51 is in a T-shaped structure, which is conducive to keeping the bearing seat 54 and the rotating shaft 53 installed horizontally. The transmission mode of the meshing of the gear 45 and the rack 46 is adopted, which has accurate matching and smooth transmission effect, which is conducive to ensuring the smooth change of the spacing of the electromagnet 5 and improving the reliability of the operation. It also has a compact structure and is conducive to reducing the weight of the frame 4.

[0030] like Figure 1 and Figure 4 As shown, the column 1 includes a first column 11 and a second column 12, and the beam 2 includes a first beam 21 and a second beam 22. The second column 12 is rotatably connected to the top of the first column 11; a second mounting seat 24 is provided between the first beam 21 and the second beam 22, and the second mounting seat 24 is rotatably connected to the second beam 22. Bearings 16 are provided on the top of the first column 11 and the second mounting seat 24 to respectively meet the rotation of the second column 12 and the second beam 22. When the battery pack shell is fixed, it can not only rotate around the column 1 as the center, but also around the second mounting seat 24 as the center in the horizontal plane, so as to meet the transfer and switching of the battery pack shell at different stations on the production line. The end of the second beam 22 is a turning structure, which is convenient for connecting with the vertical longitudinal rod 3.

[0031] like Figure 4As shown, a first mounting seat 23 is provided at the top of the second column 12, and both ends of the first beam 21 are hinged to the first mounting seat 23 and the second mounting seat 24 respectively, and the first beams 21 are arranged in pairs, and the paired first beams 21, the first mounting seat 23 and the second mounting seat 24 constitute a four-bar mechanism; a connecting frame 62 is fixedly connected between the first beams 21, a bracket 6 is provided at the bottom of the second column 12, and a second cylinder 61 is connected to the first beam 21 and the bracket 6, the bottom of the second cylinder 61 is hinged to the bracket 6, and the piston rod of the second cylinder 61 is hinged to the connecting frame 62. The second cylinder 61 provides power for the rotation of the first crossbeam 21. The four-bar structure formed by the first crossbeam 21 realizes its rotation in the vertical plane, and ensures that the second mounting seat 24 and the second crossbeam 22 are always horizontal and the longitudinal rod 25 is vertical when it rotates, thereby ensuring that the frame 4 and the battery pack shell that is adsorbed and fixed are horizontal; the second cylinder 61 will be started to lift the crossbeam 2 and the longitudinal rod 25, increase the height of the frame 4, avoid collision and interference between the longitudinal rod 25 and the frame 4 and the associated mechanism when switching between workstations, and combine the rotation function of the second column 12 and the second crossbeam 22 to meet the switching function of the battery pack shell at different workstations. The second cylinder 61 body and its piston rod are both movably connected, and can be synchronously changed to a certain angle with the rotation of the first crossbeam 21, avoiding the use of rigid connection to prevent the rotation of the first crossbeam 21. A control box 15 is provided on the second column 12 on the opposite side of the second cylinder 61. The control box 15 is arranged here to facilitate wire harness management and make full use of space.

[0032] like Figure 2-2 As shown, there are two connecting plates 42, which are symmetrically arranged about the center of the gear 45, and two racks 46 are respectively engaged on both sides of the gear 45. In the above structure, the gear 45 is arranged at the center of the frame 4, and the two racks 46 can be synchronously driven to move by the rotation of the gear 45. Therefore, only one cylinder drive is needed to drive the movement of the two connecting plates 42, so that the two electromagnets 5 move at the same time and completely absorb the two ends of the battery pack shell, which is conducive to maintaining the horizontal posture of the battery pack shell when it is absorbed and improving stability. There are multiple guide rails 43 and sliders 44 to enhance the guiding effect and ensure that the direction of the connecting plate 42 is aligned when it moves.

[0033] like Figure 5 As shown, a sleeve 63 is provided on the side of the connecting frame 62, and a guide rod 64 is passed through the sleeve 63. The bottom of the guide rod 64 is hinged to the end of the second cylinder 61; and a limit seat 65 is provided on the guide rod 64 on both sides of the sleeve 63. When the second cylinder 61 lifts the first crossbeam 21, the sleeve 63 can move along the guide rod 64. The two guide rods 64 have a supporting effect on both sides of the second cylinder 61, which can improve the stability of the second cylinder 61.

[0034] like Figure 7As shown, a mounting frame 31 is provided at the bottom of the longitudinal rod 25, and the mounting frame 31 is inclined. A button box 32 is provided on the mounting frame 31. The mounting frame 31 is inclined so that the operator can control the clamping and loosening of the battery pack shell.

[0035] like Figure 2-2 As shown, the connecting plate 42 is L-shaped, and weight-reducing holes 47 are evenly distributed on the connecting plate 42. The L-shaped connecting plate 42 is conducive to fully utilizing the space at the bottom of the frame 4, and the weight-reducing holes 47 can reduce the weight of the entire frame 4 and reduce the load-bearing burden of the column 1, the beam 2 and the longitudinal rod 25.

[0036] like Figure 8 As shown, a bottom plate 13 is provided at the bottom of the first column 11, and a reinforcing rib 14 is fixedly connected between the first column 11 and the bottom plate 13; the frame 4 is formed by welding square tubes, and a reinforcing plate 49 is provided on the frame 4. The bottom plate 13 can be fixed on the ground, and the bottom plate 13 and the reinforcing rib 14 are used to improve the stability of the column 1. The reinforcing rib 14 is provided at the welding position of the frame 4 to further strengthen the structure of the frame 4.

[0037] like Figure 2-1 As shown, a lifting ring 48 is provided at the end of the frame 4. The lifting ring 48 is used to connect the wire rope. When the frame 4 and the longitudinal rod 25 are disassembled, the frame 4 can be transported and stored in a designated location as a whole.

[0038] The implementation process is as follows: when the battery pack shell needs to be flipped, the battery pack shell is transported to the bottom of the frame 4. According to the size of the battery pack shell, the first cylinder 41 is started to adjust the distance between the two connecting rods 51, so that the electromagnet 5 adsorbs and fixes the two ends of the battery pack shell, and then the battery pack shell is manually flipped to complete the subsequent operation process.

[0039] When it is necessary to switch the workstation, the second cylinder 61 is started to lift the first beam 21, and the first beam 21 drives the second beam 22, the longitudinal rod 25, the frame 4 and the fixed battery pack shell to rise to a certain height. The rotation angle of the second beam 22 or the second column 12 is manually adjusted to a suitable position, and then the second cylinder 61 is reset to lower the height of the battery pack shell and release the fixation of the battery pack shell, thereby realizing the workstation switching function.

[0040] The battery pack shell flipping hoist meets the flipping requirements of battery packs of different specifications and sizes when working on both sides, replacing the manual handling method used in traditional technology, improving work efficiency, reducing labor intensity, and reducing safety risks; it also has multi-directional angle adjustment and height change functions, high versatility, and meets the switching and transportation requirements of different workstations on the production line. The structure and function are reliable and can effectively reduce development costs.

[0041] The present invention is described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-mentioned methods. As long as various non-substantial improvements are made using the method concept and technical solution of the present invention; or the above concept and technical solution of the present invention are directly applied to other occasions without improvement, they are all within the protection scope of the present invention.
