Description

Technical Field

[0001] This utility model relates to the field of battery production equipment technology, and in particular to a tray mechanism. Background Technology

[0002] Existing battery modules are carried on trays during processes such as positive and negative terminal cleaning and series welding of polarity connection conductive sheets on the production line. These trays utilize rows of compatible adjustment threaded holes on the bottom plate and elongated slotted holes machined into the corresponding mounting brackets to accommodate different sized battery cell modules and enable micro-adjustment. However, changing the shape of this type of tray requires special tools to loosen and remove all the fixing screws on the adjustable side, then adjusting the side to the appropriate threaded hole, reinstalling all the fixing screws on the mounting bracket, and finally adjusting using the slotted holes on the mounting bracket to accommodate the changed battery cell module. This adjustment process is quite complex. Utility Model Content

They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0026] 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 herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Please refer to Figures 1 to 8 A tray mechanism includes a tray frame 1, a main pad strip 2, and a secondary pad strip 3. The main pad strip 2 is disposed on the tray frame 1 and extends along a first direction X. The secondary pad strip 3 is disposed on the tray frame 1 and parallel to the main pad strip 2. The secondary pad strip 3 can move closer to or further away from the main pad strip 2 along a second direction Y. A battery module is attached to the main pad strip 2 and the secondary pad strip 3 adjacent to the main pad strip 2. Both the first direction X and the second direction Y are parallel to the upper surface of the tray frame 1, and the first direction X is perpendicular to the second direction Y. The tray frame 1 is provided with a first fixing rack 11 extending along the second direction Y. The secondary pad strip 3 is provided with a first positioning component 30 adapted to the first fixing rack 11. The first positioning component 30 includes a first positioning rack 31 capable of engaging with the first fixing rack 11. Figure 1 and Figure 7 As shown, the first direction X is parallel to the length direction of the battery module, and the second direction Y is parallel to the width direction of the battery module. In this embodiment, there is one main pad 2 and two auxiliary pads 3. The main pad 2 is positioned between the two auxiliary pads 3, allowing for simultaneous operation of two battery modules. During use, the auxiliary pads 3 move closer to or further away from the main pad 2 along the second direction Y to accommodate battery modules of different widths. When the auxiliary pad 3 is in the appropriate position, it is fixed by engaging the first positioning rack 31 with the first fixing rack 11. This method is more convenient than the traditional method of using rows of threaded holes with grooved holes.

[0028] In this embodiment, the secondary pad 3 is slidably connected to the tray frame 1 via a slide rail slider, so that the secondary pad 3 moves closer to or further away from the main pad 2 along the second direction Y.

[0029] Furthermore, the secondary pad 3 is provided with two first right-angle sliding blocks 34, and the battery module on the secondary pad 3 is positioned between the two first right-angle sliding blocks 34. The first right-angle sliding blocks 34 can slide along the first direction X. The secondary pad 3 is provided with a second fixed rack 32, the extension direction of the second fixed rack 32 being parallel to the extension direction of the secondary pad 3. The first right-angle sliding block 34 is provided with a second positioning component 330 adapted to the second fixed rack 32. The second positioning component 330 includes a second positioning rack 33 that can be engaged with the second fixed rack 32. Here, the first right-angle sliding block 34 is used to limit the battery module in the length direction of the battery module. As before, the positioning and fine adjustment of the first right-angle sliding block 34 are achieved by rack engagement. In this embodiment, the first right-angle sliding block 34 is slidably connected to the secondary pad 3 through a slide rail slider assembly.

[0030] like Figure 4 As shown, the first right-angle sliding block 34 is provided with a first limiting surface 341 and a second limiting surface 342 that are perpendicular to each other. The first limiting surface 341 corresponds to the end face of the battery module in the length direction, and the second limiting surface 342 corresponds to the side face of the battery module in the width direction. A first buffer member is provided on both the first limiting surface 341 and the second limiting surface 342. Specifically, the first buffer member includes a clamping plate 343, one end of which is hinged to the limiting surface. A first buffer spring 344 is provided between the clamping plate 343 and the limiting surface. The limiting surfaces are the first limiting surface 341 and the second limiting surface 342. When in use, after the battery module comes into contact with the clamping plate 343, the first buffer spring 344 is compressed. Therefore, when there is a slight error between different individual battery modules of the same specification (a slight error means that it does not need to be adjusted by the aforementioned gear meshing method), the first buffer spring 344 reacts to the battery module to ensure that the inherent deviation (tolerance) of different battery modules does not dynamically deviate, and always ensures the coordinate stability of different battery modules of the same specification on the tray frame 1.

[0031] The main pad strip 2 includes a pad strip body 21 corresponding to the secondary pad strip 3. The pad strip body 21 is disposed on the tray frame 1. The tray frame 1 is provided with a third fixing rack 22 and a second right-angle sliding block 23. The second right-angle sliding block 23 is provided with a third positioning component 35 adapted to the third fixing rack 22. The third positioning component 35 includes a third positioning rack 351 that can engage with the third fixing rack 22. In this embodiment, the second right-angle sliding block 23 corresponds to the first right-angle sliding block 34, as shown below. Figure 1As shown, there are two pad bodies 21, corresponding to the two sub-pads 3. The battery module is mounted on the sub-pad 3 and the corresponding pad body 21. In this embodiment, the second right-angle sliding block 23 and the first right-angle sliding block 34 have the same structure. The two second right-angle sliding blocks 23 located on the same side of the axis of the main pad 2 are integrally set, so that they can share the same third fixing rack 22 and third positioning component 35 to achieve position adjustment.

[0032] In this embodiment, the first positioning component 30, the second positioning component 330, and the third positioning component 35 have the same structure. For example... Figure 6 As shown, the first positioning component 30 is used as an example for explanation. Specifically, the first positioning component 30 also includes a positioning block 301, on which a guide groove 3010 is provided. The first positioning rack 31 is at least partially slidably embedded in the guide groove 3010. A support plate 302 is mounted on the positioning block 301, and a pull pin is disposed on the support plate 302. The pull pin is connected to the first positioning rack 31. In use, the pull pin acts on the first positioning rack 31, causing it to have a tendency to move towards the first fixed rack 11, so that the structure is stable when the first positioning rack 31 and the first fixed rack 11 are engaged. When it is necessary to adjust the position of the secondary pad 3 or the first right-angle sliding block 34, the pull pin is pulled to disengage the first positioning rack 31 from the first fixed rack 11. After adjusting the secondary pad 3 or the first right-angle sliding block 34 to the appropriate position, the pull pin is released, so that the first positioning rack 31 and the first fixed rack 11 are engaged.

[0033] Furthermore, such as Figure 1 and Figure 3 As shown, a first pressure block 24 is provided on the tray frame 1. The first pressure block 24 is located at the middle of the extending direction of the pad strip body 21. The first pressure block 24 corresponds to the pad strip body 21. A main reference block 25 is slidably mounted on the first pressure block 24 via a slide rail slider assembly. A second buffer spring 26 is provided between the main reference block 25 and the tray frame 1. The main reference block 25 and the first pressure block 24 form a limiting space for limiting the battery module. Figure 7 As shown, when this tray mechanism is applied to two single-row battery modules 41, the main reference block 25 is located on the side of the single-row battery module 41 in the width direction, and the first bearing block 24 is flush with the pad body 21, used to support the single-row battery module 41 in the longitudinal direction. Figure 8As shown, this tray mechanism is applied to a dual-row battery module 42. The main reference block 25 is pressed down and compresses the second buffer spring 26, supporting the dual-row battery module 42 longitudinally along with the first bearing block 24 and the pad body 21. Its positioning is handled by four first right-angle sliding blocks 34 located on the secondary pad 3, while the second right-angle sliding blocks 23 located on the main pad 2 are moved away to avoid interfering with the dual-row battery module 42. This improves the adaptability of the tray mechanism, enabling the processing of battery modules of various specifications.
