Description

Technical Field

[0001] This utility model relates to the field of battery manufacturing technology, and in particular to a vacuum adsorption hoisting and transfer device for battery modules. Background Technology

[0002] Current energy storage products and electric vehicle battery modules are composed of multiple battery cells stacked together, specifically arranged in a 17x3 grid. The total weight of a battery module can reach 310 kg. Adjacent cells are bonded together by compression and adhesive, with no other fixed connections. Currently, standard mechanical lifting tools are used to connect to the lifting holes on the end plates of the battery module, which are then transported to other locations (the next section of the production line or inside a housing). Throughout this process, the battery module remains suspended in mid-air. The adhesive strength between two cells is insufficient to counteract the weight of the cells themselves, causing the entire battery module to sag into an abnormal, arched bridge shape. This poses a significant risk of sliding and falling, as well as risks of personal injury and asset damage. Utility Model Content

[0026] To facilitate understanding of this invention, a more comprehensive description of the invention will be provided below with reference to specific embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this invention.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0028] Reference Figure 1 This embodiment proposes a vacuum adsorption hoisting and transfer device for battery modules, which includes a hoisting plate 10, an elastic pad 20, a vacuum pumping device 30, and a fall-prevention clamping mechanism 40.

[0029] To adapt to the battery module, combined with Figure 2 In this embodiment, the lifting plate 10 adopts a rectangular structure. The lifting plate 10 has a vacuum channel inside and multiple adsorption holes 11 are opened at its bottom. To facilitate lifting, four rectangularly distributed hooks 12 are provided on the top of the lifting plate 10, which facilitate the connection between the lifting plate 10 and the lifting equipment.

[0030] To facilitate control of vacuuming in the vacuum channel, a manual valve 13 and a vacuum gauge are installed on the top of the lifting plate 10. The manual valve 13 is connected to the vacuum channel, and the connection between the vacuum channel and the external vacuuming equipment 30 can be controlled via the manual valve 13. The vacuum gauge is used to detect the vacuum level in the vacuum channel. In this embodiment, two types of vacuum gauges are provided: a digital vacuum gauge 14 and a mechanical vacuum gauge 15. These two types of vacuum gauges work together to detect the vacuum level in the vacuum channel, ensuring safe transport.

[0031] Furthermore, to facilitate precise positioning of the battery module before hoisting and transportation, in this embodiment, two guide plates 17 are provided on both sides of the length direction of the hoisting plate 10, and two guide plates 2 are provided on both sides of the width direction of the hoisting plate 10. Protective pads 1 and 2 are respectively provided on the side of the guide plates 17 and 2 near the hoisting plate 10. Before hoisting, the hoisting equipment moves the hoisting plate 10 to the battery module and slowly lowers the hoisting plate 10. The guide plates 17 and 2 play a guiding and assisting role to ensure that each adsorption hole 11 can be aligned with the designated position of the battery module, which facilitates the adsorption and transportation operation.

[0032] An elastic pad 20 is disposed at the bottom of the lifting plate 10. In this embodiment, the elastic pad 20 is made of sponge. Figure 3The elastic pad 20 has adsorption grooves 21 extending through it at positions corresponding to each adsorption hole 11. Some of these adsorption grooves 21 are adapted to the terminals of the battery cells, while others are adapted to the explosion-proof valves of the battery cells. Thus, when the lifting plate 10 is placed on the surface of the battery module, the terminals and explosion-proof valves of each battery cell extend into their respective adsorption grooves 21. The adsorption grooves 21 on the elastic pad 20 allow for point-to-point adsorption of the terminals and explosion-proof valves of the battery cells, improving the adhesion and adsorption force between the elastic pad 20 and the surface of each battery cell.

[0033] The vacuum pumping device 30 is used to evacuate the vacuum channel. In this embodiment, the vacuum pumping device 30 includes a vacuum pump 31 and a vacuum tank 32. The vacuum pump 31 is connected to the vacuum tank 32 through a pipe, and the vacuum tank 32 is connected to the manual valve 13 through a pipe. The vacuum pump 31 generates a stable negative pressure gas and stores it in the vacuum tank 32. When the manual valve 13 is opened manually, a negative pressure begins to be generated inside the vacuum channel. The digital vacuum gauge 14 and the mechanical vacuum gauge 15 display the negative pressure value of the vacuum channel. When the negative pressure value reaches a set threshold, the elastic pad 20 can be compressed tightly, forming a sealed negative pressure space between the elastic pad 20 and the battery module. The elastic pad 20 and the battery module are tightly attached together. After the manual valve 13 is closed, the negative pressure between the elastic pad 20 and the battery module is maintained, and the battery module can be transferred to the designated location by the hoisting equipment.

[0034] To prevent accidents during transport, this embodiment also includes a fall-prevention clamping mechanism 40 to clamp the battery module. In this embodiment, the fall-prevention clamping mechanism 40 includes two fall-prevention clamping assemblies, which are installed opposite each other at both ends of the lifting plate 10 along its length. Each fall-prevention clamping assembly includes two clamping arms 41 and an adjusting member. The two clamping arms 41 are positioned opposite each other on both sides of the lifting plate 10 along its width, and each clamping arm 41 has a pin 42 at its bottom and a mounting base 43 connected to its top. Two slide rails 16 are provided at both ends of the lifting plate 10 along its width, and four mounting bases 43 are respectively connected to the sliders of the four slide rails 16. The adjusting member is used to adjust the distance between the two mounting bases 43 in the width direction of the lifting plate 10. Figure 2 , Figure 4The adjusting components include a fixed base 44, a handle 45, a push rod 46, two connecting rods 47 and 48. The fixed base 44 is fixed to the top of the lifting plate 10 and is located on the side of one mounting seat 43 away from the other. A retaining seat 49 is provided on the top of the mounting seat 43 near the fixed base 44. One end of the handle 45 is rotatably mounted on the fixed base 44 and is rotatably connected to a connecting plate 410. The end of the connecting plate 410 away from the handle 45 is rotatably connected to the push rod 46. The push rod 46 is horizontally arranged and its end away from the connecting plate 410 is engaged with the retaining seat 49. One end of each of the two connecting rods 47 is rotatably connected to one of the two mounting seats 43, and the other end of each of the two connecting rods 47 is rotatably connected to both ends of the connecting rod 48. A mounting shaft 411 is rotatably connected to the middle of the connecting rod 48 and is fixed to the lifting plate 10. Thus, after placing the lifting plate 10 on the surface of the battery module, manually turn the handle 45 to pull and push it to move it, causing the two mounting seats 43 to move closer to each other, so that the pin 42 of the clamping arm 41 can be inserted into the lifting hole of the battery module end plate, thereby clamping the battery module.

[0035] In this embodiment, the battery module vacuum adsorption hoisting and transfer device first slowly places the hoisting plate 10 onto the battery module to be transferred, guided by guide plate 17 and guide plate 18, so that the battery module's terminals and explosion-proof valve can enter the corresponding adsorption tank 21. Then, manually turn the handle 45 to pull the push rod 46 to move, causing the two mounting seats 43 to move closer to each other, so that the pin 42 of the clamping arm 41 is inserted into the hoisting hole of the battery module end plate, clamping the battery module. Then, open the manual valve 13 to connect the vacuum channel with the vacuum tank 32. Due to the negative pressure environment in the vacuum tank 32, a negative pressure is gradually generated between the vacuum channel, the elastic pad 20, and the battery module. The elastic pad 20 gradually contracts and adheres tightly to the top surface of the battery module. When the negative pressure value reaches the set threshold, the negative pressure between the elastic pad 20 and the battery module is maintained, and the battery module is transferred to the designated position by the hoisting equipment. Then, close the manual valve to break the vacuum, the elastic pad 20 separates from the battery module, and the transfer of the battery module is completed, so that the transfer of the next battery module can be carried out.

[0036] When the battery module vacuum adsorption hoisting and transfer device of this embodiment is not in operation, the hoisting plate 10 can be placed directly on the dedicated frame 50.

[0037] It should be noted that when a component is said to be "installed on" another component, it can be directly on the other component or it may be in a component that is centered on it. When a component is said to be "set on" another component, it can be directly set on the other component or it may also be in a component that is centered on it.
