Detailed implementation manners

[0028] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Those skilled in the art should know that the following described embodiments are part of the embodiments of the present disclosure, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present utility model.

[0029] When the utility model is in use, the shell and the inner core are stacked in the blanking barrel and the stacking barrel respectively. When the device is operating normally, the conveying motor drives the conveying belt for transportation. At this time, the shell in the blanking barrel falls from the shell discharge port and falls between the partitions. Then, under the action of the conveying belt, it is clamped and transported by the partition and the fixed baffle. When the shell passes through the inner core discharge port, it pauses, and the inner push cylinder drives the inner push block to move. The inner core at the bottom of the storage barrel is loaded into the shell under the action of the inner push block, thereby completing the preliminary assembly of the lithium battery.

[0030] After introducing the basic principle of the utility model, various non-limiting embodiments of the utility model are specifically introduced below. Any number of elements in the drawings is for illustration and not for limitation, and any naming is only for distinction and does not have any limiting meaning.

[0031] The principle and spirit of the present invention are explained in detail below with reference to several representative embodiments of the present invention.

[0032] Embodiment 1 of the lithium battery assembly device provided by the utility model:

[0033] like Figure 1 As shown, the lithium battery assembly device includes a base 1, a conveying mechanism 2, a shell material discharge mechanism 3 and an inner core installation mechanism 4.

[0034] like Figure 1 As shown, the base 1 includes a bottom plate 11 and a mounting side plate 12 vertically mounted on the top of the bottom plate 11 .

[0035] like Figure 1 and Figure 2 As shown, the conveying mechanism 2 is fixedly connected to the mounting side plate 12, and the conveying mechanism 2 includes two conveying wheels 21 arranged at intervals. A conveying motor 26 for driving the conveying wheels 21 to rotate is installed on the mounting side plate 12, and the conveying motor 26 is transmission-connected to any conveying wheel 21. A conveying belt 22 is wound around the two conveying wheels 21, and conveying baffles 23 are installed at intervals on the conveying belt 22. The spacing between the conveying baffles 23 corresponds to the size of the shell. A load-bearing plate 25 for supporting the conveying belt 22 is provided between the two conveying wheels 21, and rollers are evenly distributed on the load-bearing plate 25 horizontally to reduce the friction between the conveying belt 22 and the load-bearing plate 25. A fixed baffle 24 for positioning is installed on the side of the load-bearing plate 25 away from the mounting side plate 12, and the fixed baffle 24 is fixedly connected to the load-bearing plate 25 in an L shape, and the fixed baffle 24 is close to the conveying belt 22 and is in a vertical relationship with the conveying belt 22. The fixed baffle 24 and the conveying baffle 23 on the conveying belt 22 are in a semi-enclosed structure, which plays a fixing role on the shell during the battery assembly process.

[0036] like Figure 1As shown, the conveying mechanism 2 is provided with a shell unloading mechanism 3 and an inner core mounting mechanism 4 in sequence along its conveying direction. The shell unloading mechanism 3 is used for cooperating with the conveying mechanism 2 for unloading. The shell unloading mechanism 3 comprises a blanking barrel 31 vertically arranged above the conveying mechanism 2. The blanking barrel 31 is fixedly connected to the mounting side plate 12. The blanking barrel 31 is provided with a shell cavity for storing the shell. The shell opening in the shell cavity faces the mounting side plate 12. The shell feed port and the shell blanking port are respectively provided at the top and the bottom of the shell cavity.

[0037] like Figure 1 and Figure 2 As shown, the inner core installation mechanism 4 includes a storage barrel 41 vertically arranged on the side of the conveying mechanism 2, the storage barrel 41 is provided with an inner core cavity for storing the inner core, the top of the inner core cavity is provided with an inner core feeding port 42, and the bottom of the inner core cavity is fixedly provided with a support plate 43 for supporting the inner core, and the storage barrel 41 is provided with an inner core discharge port 44 below the side wall near the conveying mechanism 2, and the support plate 43 is also provided with an inner push cylinder 45 for pushing the inner core into the shell body, and an inner push block 451 is fixedly connected to the output shaft of the inner push cylinder 45, and a limiting plate 452 is vertically fixedly connected around the support plate 43, and the limiting plate 452 limits the inner push block 451 when the inner push cylinder 45 is running to prevent it from deviating from the installation track, and an avoidance hole for the inner push block 451 to pass through is provided at the bottom of the storage barrel 41. During the initial assembly, the inner push block 451 passes through the avoidance hole to push the inner core into the shell body.

[0038] like Figure 1 and Figure 2 As shown, the conveying motor 26 and the inner push cylinder 45 operate in conjunction, and the shell falls from the blanking barrel 31 to between the conveying partitions 23 due to gravity. Then the conveying motor 26 pauses when conveying the shell to the inner core discharge port 44, and the inner push cylinder 45 drives the inner push block 451 to load the inner core at the bottom of the storage barrel 41 into the shell. Then the inner push block 451 contracts, and the conveying motor 26 continues to operate to complete the preliminary assembly of the lithium battery.

[0039] Embodiment 2 of the lithium battery assembly device provided by the utility model:

[0040] The main difference between it and Example 1 is:

[0041] In Example 1, the shell falls between the conveying partitions 23 under the action of gravity and is then transported to the inner core installation mechanism 4.

[0042] like Figure 3 and Figure 4As shown in the figure, a housing positioning mechanism is added in this embodiment. The housing positioning mechanism includes a wedge block 51, which is fixedly connected to an inner push block 451. Sliding grooves for facilitating the sliding of the wedge block 51 and the inner push block 451 are formed on both side walls of the storage cylinder 41. There is a support rod 52 above the wedge block 51. A positioning rod 54 is fixedly installed on the mounting side plate 12. There is a sleeve 55 at the front end of the positioning rod 54. The support rod 52 moves up and down in the sleeve 55 under the action of the wedge block 51. An connecting rod 53 is provided above the support rod 52. The contact position between the connecting rod 53 and the support rod 52 is defined as the front end. A tension spring 57 is provided between the front end of the connecting rod 53 and the positioning rod 54. The middle position of the connecting rod 53 is hinged to the mounting side plate 12 through an angle iron. The end of the connecting rod 53 is connected with a pressing block 56;

[0043] As Figure 3 and Figure 4 shown, there is a certain distance between the initial position of the inner push block 451 and the inner core in the storage cylinder 41. When assembling the inner core, the inner push cylinder 45 drives the inner push block 451 and the wedge block 51 to move together. At this time, before the wedge block 51 and the inner push block 451 contact the inner core, the wedge block 51 first pushes the support rod 52 to move upward in the sleeve 55. The front end of the connecting rod 53 is lifted by the extrusion of the support rod 52, and the end drives the pressing block 56 to press down to complete the housing positioning. Then the inner push block 451 contacts the inner core to perform inner core filling.

[0044] As Figure 3 and Figure 4 shown, after the positioning is completed, the support rod 52 moves horizontally on the top of the wedge block 51 to keep the pressure of the pressing block 56 on the housing unchanged; after the inner core filling is completed, the inner push block 451 drives the wedge block 51 to withdraw, and the support rod 52 descends along the sleeve 55. At this time, the front end of the connecting rod 53 loses support, and the connecting rod 53 descends due to the action of the tension spring 57, and the pressing block 56 is released, and the positioning is released.

[0045] A housing positioning mechanism is added in this embodiment, which avoids the inclination problem caused by the housing not being able to fit the conveying partition 23 completely. The inclined housing is positioned by the pressing block 56, and then the inner core filling is completed.

[0046] Embodiment 3 of the lithium battery assembly device provided by the present utility model:

[0047] The main difference between it and Embodiment 1 is:

[0048] As Figure 5 shown, in this embodiment, the square conveying partition is replaced with a conveying partition with a smooth slope at the upper end. When the falling position of the housing is offset, the housing can slide down along the slope for positioning.

[0049] The above is inspired by the ideal embodiments of the present utility model, but it is obvious to those skilled in the art that such embodiments are provided only by way of example. Those skilled in the art will think of many changes, alterations and alternative ways without departing from the spirit and concept of the present utility model. It should be understood that various alternative solutions of the embodiments of the present utility model described herein can be adopted in the process of practicing the present utility model. The appended claims are intended to define the protection scope of the present utility model and thus cover the module compositions, equivalents or alternative solutions within the protection scope of these claims.
