Description

A battery module hoisting fixture Technical Field

[0001] This utility model relates to the field of battery module hoisting, specifically to a battery module hoisting clamp. Background Technology

[0002] With the rise of new energy technologies, the advantages of lithium batteries over other types of batteries have become increasingly apparent, and the technology for assembling lithium batteries has also matured. After the lithium battery is assembled, it needs to be transported to facilitate the movement of the lithium battery module from the production line to the offline production line, and then to the warehouse or the next production line.

[0003] The handling of lithium battery modules involves lifting fixtures, which are divided into three categories: manual, semi-automatic, and fully automatic. Semi-automatic and fully automatic lifting fixtures are expensive, while manual lifting fixtures are simple in structure, easy to use, and affordable, making them more suitable for small-scale factory assembly.

[0004] On the production line, workers need to rely on their eyesight and experience to precisely align the installation part of the battery module with the lifting holes of the clamping module end plate. However, visual errors of the human eye and fatigue caused by long-term operation can easily cause positioning deviations. According to relevant statistics, under this manual positioning method, the positioning error can reach an average of ±0.5mm, and in severe cases, it can even exceed ±1mm.

[0005] Even more challenging is the fact that the tooling's structural design obstructs the worker's view when operating the side lifting holes. Workers are forced to frequently change angles and adjust their line of sight just to barely see the location of the lifting holes. This obstructed view significantly affects the smoothness of the operation, not only greatly reducing employee efficiency and slowing down the overall production progress, but also potentially increasing the risk of collision between the battery module and the tooling due to repeated adjustments, thereby affecting the surface quality of the battery module and the service life of the tooling.

[0006] In summary, the applicant has proposed a battery module hoisting fixture. Summary of the Invention

[0007] The purpose of this utility model is to provide a battery module hoisting fixture to save labor costs and improve network security. To achieve the above technical objectives, the technical solution of this utility model is as follows:

[0008] A battery module hoisting fixture includes a main support frame, and further includes:

[0009] A control structure, which is mounted on the top of the main support;

[0010] A longitudinal positioning structure is installed in the middle of the main support;

[0011] The transverse positioning structure is provided in two sets and is symmetrically installed on both sides of the bottom of the main support.

[0012] The clamping structure is provided in two sets, and is respectively installed on the two sets of transverse positioning structures.

[0013] Furthermore, the control structure includes an operating handle mounted on the rear top of the main support, a control button mounted on the operating handle, and a quick-change section mounted at the center of the top of the main support.

[0014] Furthermore, the longitudinal positioning structure includes a fixing plate symmetrically arranged along the cross-section of the main support, an L-shaped plate installed on the outside of the fixing plate, and a pad installed on the bottom of the inner side of the L-shaped plate.

[0015] Furthermore, the lateral positioning structure includes a changing cylinder installed at the bottom of the main support, a Y-shaped plate connected to the output shaft of the changing cylinder, and positioning shafts and limiting shafts installed at both ends of the Y-shaped plate;

[0016] The Y-shaped plate is slidably connected to the bottom of the main support.

[0017] Furthermore, the clamping structure includes a mounting base fixedly connected to the bottom of the Y-shaped plate, a clamping cylinder disposed on the mounting base, a sliding plate connected to the output end of the clamping cylinder, a clamping plate fixedly connected to the outside of the sliding plate, and a soft pad and a contour block installed on the bottom of the inner side of the clamping plate.

[0018] After improvement, this utility model further produces the following beneficial effects:

[0019] 1. This solution uses a control structure to sequentially control the lateral positioning structure and clamping structure, and works in conjunction with the longitudinal positioning structure to complete the automatic positioning and clamping of the battery assembly. The operator only needs to hold the operating handle and use the control buttons to operate the clamping structure, lateral positioning structure, etc. The operation is simple and easy to understand, which not only solves the problem of errors that may occur in manual positioning, but also greatly improves work efficiency.

[0020] 2. The quick-change section of this solution adopts a bayonet connection structure. Compared with the traditional fixed connection method, when changing the lifting clamp, the operator only needs to perform a simple plug-and-play operation to complete the separation or installation of the clamp and the lifting equipment within 1 minute, which greatly shortens the equipment changeover time and improves the switching efficiency of handling different specifications of battery modules on the production line.

[0021] 3. This solution, through the cooperation of the lateral and longitudinal positioning structures, can accurately position the battery module longitudinally according to its height, ensuring that the battery module is at the appropriate height during hoisting. The changing cylinder in the lateral positioning structure can drive the Y-shaped plate to slide, thereby adjusting the position of the positioning axis and the limit axis, so that it can adapt to battery modules of different widths, greatly improving the versatility of the hoisting fixture, reducing the need to change the hoisting fixture due to different battery module specifications, and reducing production costs.

[0022] 4. The clamping cylinder in this solution provides a stable and adjustable clamping force. The action of the clamping cylinder can be precisely controlled by the control button to avoid damage to the battery module due to improper clamping force. The soft pad and contour block on the bottom inner side of the clamping plate provide cushioning and prevent the clamping plate from directly contacting the surface of the battery module, thus preventing scratches and damage. The contour block can be adapted to the shape of the battery module, increasing the stability of clamping and effectively preventing the battery module from shaking and falling during hoisting, ensuring the safety of the operator and the integrity of the battery module.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] As shown in Figures 1, 2, and 3, a battery module hoisting fixture includes a main support 1, and further includes:

[0029] Control structure 2, which is installed on the top of the main support 1;

[0030] Longitudinal positioning structure 3, which is installed in the middle of the main support 1;

[0031] The transverse positioning structure 4 is provided in two sets and is symmetrically installed on both sides of the bottom of the main support 1.

[0032] The clamping structure 5 is provided in two sets, and is respectively installed on the two sets of transverse positioning structures 4.

[0033] The control structure 2 includes an operating handle 21 installed on the rear top of the main support 1, a control button 22 installed on the operating handle 21, and a quick-change section 23 installed at the center of the top of the main support 1.

[0034] It should be noted that the quick-change section 23 adopts a bayonet connection structure. Compared with the traditional fixed connection method, when changing the lifting clamp, the operator only needs to perform a simple plug-and-play operation to complete the separation or installation of the clamp and the lifting equipment within 1 minute, which greatly shortens the equipment changeover time and improves the switching efficiency of handling different specifications of battery modules on the production line.

[0035] In addition, operators can achieve precise control of the changing cylinder 41 and the clamping cylinder 52 by using the control button 23 on the operating handle 21. The layout of the control button 23 conforms to the ergonomic design, with a short operating stroke and sensitive feedback. Even new employees can master the operating skills in a short time after simple training, reducing the difficulty of manual operation and training costs.

[0036] The longitudinal positioning structure 3 includes a fixing plate 31 symmetrically arranged along the cross-section of the main support 1, an L-shaped plate 32 installed on the outside of the fixing plate 31, and a pad 33 installed on the bottom of the inner side of the L-shaped plate 32.

[0037] The lateral positioning structure 4 includes a changing cylinder 41 installed at the bottom of the main support 1, a Y-shaped plate 42 connected to the output shaft of the changing cylinder 41, and a positioning shaft 43 and a limiting shaft 44 installed at both ends of the Y-shaped plate 42.

[0038] The Y-shaped plate 42 is slidably connected to the bottom of the main support 1.

[0039] It should be noted that the longitudinal positioning structure 3 and the transverse positioning structure 4 work together to ensure that the battery module maintains a stable posture during hoisting, which greatly reduces the probability of safety accidents.

[0040] In addition, when hoisting the battery module, the positioning shaft 43 is first inserted into the positioning hole on the side of the battery module to play a preliminary positioning role. Then, the position of the Y-shaped plate 42 is adjusted by the changing cylinder 41 so that the limiting shaft 44 is aligned with the other edge of the battery module to further refine the lateral position.

[0041] The clamping structure 5 includes a mounting base 51 fixedly connected to the bottom of the Y-shaped plate 42, a clamping cylinder 52 disposed on the mounting base 51, a sliding plate 53 connected to the output end of the clamping cylinder 52, a clamping plate 54 fixedly connected to the outside of the sliding plate 53, and a soft pad 55 and a contour block 56 installed on the bottom inner side of the clamping plate 54.

[0042] It should be noted that the soft pad 55 is made of silicone or rubber, which has good cushioning performance and can effectively disperse the clamping force to avoid damage to the battery module shell; the contour block 56 is designed according to the common shape of the battery module and fits tightly with the surface of the battery module, increasing the friction and preventing the battery module from sliding during hoisting.

[0043] The specific working method is described below using specific embodiments: Embodiment 1

[0044] When the operator grips the handle to prepare for hoisting the battery module, first, based on the approximate size of the battery module, the operator activates the changing cylinder 41 via control button 22. The changing cylinder 41 pushes the Y-shaped plate 42 to slide at the bottom of the main support 1, adjusting the positions of the positioning shaft 43 and the limiting shaft 44 to fit the width of the battery module. Then, the hoisting fixture is moved above the battery module, and the pad of the longitudinal positioning structure 33 contacts the top of the battery module. At this time, the fixing plate 31 and the L-shaped plate 42 provide stable support, completing the longitudinal positioning. Next, the operator presses the control button 22 again to activate the clamping cylinder 52. The clamping cylinder 52 pushes the sliding plate 53 to move the clamping plate 54 closer to the battery module. The soft pad 55 and the contour block 56 fit against the side of the battery module, gradually increasing the clamping force until the set clamping force is reached, completing the clamping of the battery module. Finally, the operator controls the hoisting equipment via the operating handle 21 to smoothly lift the battery module and transport it to the designated location. Example 2

[0045] Assuming the battery module to be transported is a new model with different dimensions than the previous model, and the position and number of side lifting holes have also changed, in this case, the positioning shaft 43 and the limiting shaft 44 of the transverse positioning structure 4 are first adjusted to fit the width of the new battery module using the type-changing cylinder 41. Since the height of the new battery module has also increased, the L-shaped plate 32 of the longitudinal positioning structure can be adjusted in height using the slider adjustment, so that the pad can accurately contact the top of the battery module. During the lifting process, the operator finds that the center of gravity of the battery module is slightly off. At this time, the clamping force of the clamping cylinder 52 can be finely adjusted using the fine-tuning button on the operating handle 21 to keep the battery module balanced during the lifting process. At the same time, due to the change in the position of the side lifting holes of the new battery module, the position of the guide pin also needs to be adjusted accordingly to ensure that the positioning shaft 43 can be smoothly guided into the positioning hole. Through these adjustments, this lifting fixture can still efficiently and safely complete the transport of the new battery module, fully demonstrating its good versatility and adaptability.

[0046] The present invention has been described above by way of example with reference to the accompanying drawings.

Any non-substantial improvements made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution to other situations without modification, are all within the protection scope of the present invention.
