In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present application, so the present application is not limited by the specific embodiments disclosed below.

[0038] In the description of the present application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, the orientation or position relationship indicated by these terms is based on the orientation or position relationship shown in the accompanying drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application.

[0039] In addition, if the terms "first" or "second" appear, these terms are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0040] In this application, unless otherwise clearly specified and limited, if the terms "installed", "connected", "connected", "fixed" and the like appear, these terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to the specific circumstances.

[0041] In the present application, unless otherwise clearly specified and limited, if there is a description that a first feature is "above" or "below" a second feature, etc., or similar descriptions appear, it may mean that the first and second features are in direct contact, or that the first and second features are in indirect contact through an intermediate medium.

[0042] It should be noted that if an element is referred to as being "fixed to" or "disposed on" another element, it may be directly on the other element or there may be a central element.

If any, the terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used in this application are for illustrative purposes only and do not represent the only implementation method.

[0043] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 , an embodiment of the present application provides a battery cell spacing adjustment device, the battery cell spacing adjustment device includes a base frame 100, a support assembly 200 and a support assembly 200.

[0044] Among them, the support assembly 200 is arranged on the base frame 100, and the support assembly 200 includes a plurality of support blocks 210 distributed along the first direction X at a first preset spacing. The support blocks 210 are used to support the battery cells 600. All the support blocks 210 can slide along the first direction X. A first limiting column 220 is inserted between adjacent support blocks 210, and the first limiting column 220 can limit the relative sliding distance of adjacent support blocks 210.

[0045] The pushing mechanism 300 is used to push the first support block 210 in the first direction X to slide along the first direction X, so that all the support blocks 210 are stacked along the first direction X or distributed according to the second preset interval.

[0046] It should be noted that in the present application, the base frame 100 may be, but is not limited to, a plate-like structure, a frame structure, etc. Figure 1 , Figure 2 , the base frame 100 is preferably a plate-like structure.

[0047] In the present application, the first direction X is a linear direction, which also corresponds to the length direction of the base frame 100. Among all the support blocks 210 on the support assembly 200, the spacing between adjacent support blocks 210 is equal, which is the first preset spacing, and the first preset spacing can be adjusted according to actual conditions.

[0048] It should be understood that when multiple battery cells 600 are delivered to the assembly line from the previous process, the distance between adjacent battery cells is the first preset distance, that is, the distance between adjacent support blocks 210 on the support assembly 200 corresponds to the distance between the incoming battery cells. Before the incoming mechanism on the battery production line delivers multiple battery cells 600 from the previous process to the assembly line, the multiple battery cells 600 may be synchronously transferred to each support block 210 on the support assembly 200, and the incoming mechanism may be a multi-axis manipulator.

[0049] In this application, see Figure 7 The pushing mechanism 300 may include a first driving member 310 and a pushing block 320 disposed at the driving end of the first driving member 310. The first driving member 310 drives the pushing block 320 to move along the first direction X, so that the pushing block 320 pushes the first support block 210 in the first direction X to slide along the first direction X. The first driving member 310 may be a linear cylinder. The height of the pushing block 320 is greater than the height of the support block 210, so that the pushing block 320 can push the first support block 210 while also forming a surface contact with the battery cell 600 on the first support block 210, thereby limiting the battery cell 600 on the first support block 210 and preventing the battery cell 600 on the first support block 210 from tipping toward one side of the pushing block 320 during the sliding process along the first direction X.

[0050] The first limiting pillars 220 passing through the adjacent supporting blocks 210 can limit the relative sliding distance of the adjacent supporting blocks 210 to be less than or equal to the first preset distance.

[0051] The outer wall of the first limiting column 220 may be provided with a positioning portion (not shown in the figure) for stopping the support block 210 from sliding, and the connection position of the positioning portion relative to the first limiting column 220 can be adjusted. For example, the positioning portion is a slider that can be locked on the outer wall of the first limiting column 220, or it can be a stopper that is detachably fixed to the outer wall of the first limiting column 220 by screws.

[0052] When the positioning portion is located at the end of the first limiting column 220 and is inserted into the support block 210, the sliding of the support block 210 along the first direction X will not be stopped by the positioning portion, that is, the relative sliding distance of adjacent support blocks 210 is equal to the first preset spacing. At this time, all the support blocks 210 can be stacked together under the pushing action of the pushing mechanism 300, eliminating the spacing between adjacent battery cells 600, so that all the battery cells 600 are stacked into a whole along the first direction X.

[0053] When the positioning portion is located in the middle of the first limiting column 220 and on the outside of the support block 210, at this time, after the first support block 210 drives the battery cell 600 thereon to slide a distance in the direction close to the second support block 210, the first support block 210 is stopped by the positioning portion on the first limiting column 220. At this time, the spacing between the first support block 210 and the second support block 210 is the second preset spacing. With the continuous pushing of the pushing mechanism 300, the first support block 210 and the second support block 210 maintain the second preset spacing and slide synchronously along the first direction X towards the direction close to the third support block 210. In this way, the relative sliding distance between each adjacent support block 210 is limited by the positioning portion on the first limiting column 220, so that all the support blocks 210 are distributed along the first direction X according to the second preset spacing, so that all the corresponding battery cells 600 on all the support blocks 210 are distributed according to the second preset spacing, so that the accurate adjustment of the spacing between the battery cells 600 is achieved.

[0054] It is understandable that the second preset distance is determined by the position of the positioning portion on the first limiting column 220, and the position of the positioning portion on the outer wall of the first limiting column 220 can be selectively adjusted according to actual needs to correspondingly adjust the second preset distance.

[0055] It is not difficult to understand that when the battery cell spacing adjustment device of the present application is used in practice, the incoming material mechanism on the battery production line transfers the multiple battery cells 600 to the respective support blocks 210 on the support assembly 200, so that each battery cell 600 is placed vertically on the corresponding support block 210. At this time, the spacing between adjacent battery cells 600 corresponds to the spacing between adjacent support blocks 210, and both are the first preset spacing.

[0056] Then, the pushing mechanism 300 pushes the first support block 210 on the first direction X to slide along the first direction X, and the first support block 210 drives the battery cell 600 thereon to slide in the direction of the adjacent support block 210. By limiting the relative sliding distance of the adjacent support blocks 210 through the first limiting column 220 penetrating between the adjacent support blocks 210, all the support blocks 210 can be accurately stacked along the first direction X or distributed according to the second preset spacing under the pushing action of the pushing mechanism 300, so that all the corresponding battery cells 600 on all the support blocks 210 are distributed according to the second preset spacing. In this way, the spacing between the battery cells 600 is accurately adjusted, the consistency of adjusting the spacing between the battery cells is improved, and the efficiency of adjusting the spacing between the battery cells is also improved.

[0057] See also Figure 1 and Figure 3 In some embodiments of the present application, a fixed stopper 110 is provided on the base frame 100 , and the fixed stopper 110 is located at the last support block 210 in the first direction X so that the battery cell 600 on the last support block 210 can abut against it.

[0058] It is not difficult to understand that when the pushing mechanism 300 pushes the first support block 210 in the first direction X to slide along the first direction X, the second support block 210, the third support block 210, ..., to the last support block 210 in the first direction X will slide in sequence driven by the previous support block 210 until the last support block 210 slides to the position of the fixed stop block 110. At this time, the battery cell 600 on the last support block 210 abuts against the fixed stop block 110. On the one hand, it prevents the outer side of the battery cell 600 on the last support block 210 from tipping over, and on the other hand, it serves as an indication of the completion of the battery cell spacing adjustment.

[0059] In some embodiments of the present application, see Figure 4 , Figure 5 and Figure 6 The support assembly 200 further includes a first guide column 230 extending along the first direction X, and the first guide column 230 passes through all the support blocks 210 .

[0060] Specifically, there are a plurality of first guide pillars 230 .

[0061] It is not difficult to understand that when all the support blocks 210 slide along the first direction X, the first guide column 230 provides accurate guidance for the sliding of all the support blocks 210, ensuring that all the support blocks 210 slide along a straight line, avoiding positional deviation of the support blocks 210 and the battery cells 600 on the support blocks 210, and improving the accuracy of adjusting the spacing between the battery cells 600.

[0062] In some embodiments of the present application, see Figure 4 , Figure 5 and Figure 6 A first elastic member 240 is sandwiched between adjacent support blocks 210, and the first elastic member 240 is sleeved on the first guide column 230. The end of the first limiting column 220 away from the pushing mechanism 300 is fixedly connected to the support block 210, and the end of the first limiting column 220 close to the pushing mechanism 300 is movably arranged along the first direction X to pass through the adjacent support block 210 to stop and limit the adjacent support block 210.

[0063] Specifically, the first elastic member 240 is a compression spring. The first guide column 230 and the first limit column 220 have a height difference relative to the support block 210 to avoid mutual interference between the first guide column 230 and the first limit column 220 .

[0064] It should be noted that, in the present embodiment, the first limiting pillar 220 is located at the outer portion of the supporting block 210 without a positioning portion, so as to achieve the effect of stacking all the battery cells 900 along the first direction X.

[0065] It should also be noted that when all the support blocks 210 are in the initial position, the first elastic member 240 between adjacent support blocks 210 is in a compressed and energized state, and the adjacent support blocks 210 are maintained at a first preset distance apart by the stopping and limiting action of the first elastic member 240 and the first limiting column 220 and the support block 210.

[0066] When all the support blocks 210 are finally stacked along the first direction X under the pushing action of the pushing mechanism 300, all the battery cells 600 are also stacked along the first direction. At this time, the first elastic members 240 between each adjacent support block 210 are further compressed. When the corresponding unloading mechanism (such as a robot) takes the stacked battery cells 600 and transfers them to the next production process, the pushing mechanism 300 is reset. At this time, all the support blocks 210 are reset to the initial position under the action of the first elastic members 240, preparing for the next adjustment of the battery cell spacing.

[0067] Further, see Figure 4 , Figure 5 and Figure 6 The first limiting column 220 includes a rod portion 221 and a head portion 222 connected to the rod portion 221 , a step portion 211 is formed on the support block 210 , the rod portion 221 is threadedly connected to the support block 210 , and the head portion 222 is stop-matched with the step portion 211 on the adjacent support block 210 .

[0068] Specifically, the first limiting column 220 is configured as a bolt. A first through channel 212 extending along the first direction X is provided in the support block 210, and a step portion 211 is formed in the middle of the first through channel 212. The initial spacing between adjacent support blocks 210, i.e., the first preset spacing, is defined by the cooperation between the step portion 211 and the stopper of the head portion 222 of the first limiting column 220, so that all support blocks 210 can accurately support multiple battery cells 600 distributed at the first preset spacing. It is not difficult to understand that the purpose of adjusting the first preset spacing can be achieved by adjusting the initial compression amount of the first elastic member 240 and the position of the step portion 211 on the support block 210.

[0069] In addition, the present application can facilitate the overall disassembly, assembly and replacement of the first limiting column 220 by threading the rod portion 221 of the first limiting column 220 with the support block 210 .

[0070] In some embodiments of the present application, the first limiting column 220 has a positioning portion (not shown in the figure) for stopping the support block 210, and when the support block 210 slides along the first direction X by a preset distance, it is stopped by the positioning portion.

[0071] Specifically, the connection position of the positioning part relative to the first limiting column 220 can be adjusted. For example, the positioning part can be a slider that can be locked on the outer wall of the first limiting column 220, or a stopper that is detachably fixed to the outer wall of the first limiting column 220 by screws.

[0072] It is not difficult to understand that when the first support block 210 drives the battery cell 600 thereon to slide a certain distance in the direction close to the second support block 210, the first support block 210 is stopped by the positioning portion on the first limiting column 220. At this time, the spacing between the first support block 210 and the second support block 210 is the second preset spacing. As the pushing mechanism 300 continues to push, the first support block 210 and the second support block 210 maintain the second preset spacing and slide synchronously along the first direction X in the direction close to the third support block 210. In this way, the relative sliding distance between each adjacent support block 210 is limited by the positioning portion on the first limiting column 220, so that all the support blocks 210 are distributed along the first direction X according to the second preset spacing, so that all the corresponding battery cells 600 on all the support blocks 210 are distributed according to the second preset spacing, so that the accurate adjustment of the spacing between the battery cells 600 is achieved.

[0073] It is understandable that the second preset distance is determined by the position of the positioning portion on the first limiting column 220, and the position of the positioning portion on the outer wall of the first limiting column 220 can be selectively adjusted according to actual needs to correspondingly adjust the second preset distance.

[0074] In some embodiments of the present application, see Figure 1 , Figure 2 and Figure 3 The battery cell spacing adjustment device also includes two side pressure assemblies 400 spaced apart from each other relative to the support assembly 200. The side pressure assembly 400 includes a plurality of side pressure blocks 410 distributed along a first direction X at a first preset spacing. All the side pressure blocks 410 can slide along the first direction X. The side pressure blocks 410 are used to press the sides of the battery cell 600 when the support block 210 drives the battery cell 600 to slide.

[0075] Specifically, two side pressure assemblies 400 are distributed on opposite sides of the support assembly 200 , and the direction perpendicular to the first direction X is defined as the second direction Y. It is understandable that each battery cell 600 supported on the support block 210 has a side pressure block 410 distributed on opposite sides along the second direction Y respectively.

[0076] See also Figure 8 and Fig. 9The side pressure assembly 400 can slide along the second direction Y relative to the base frame 100. The side pressure assembly 400 includes a mounting plate 430 and a second driving member 440 drivingly connected to the mounting plate 430. A plurality of side pressure blocks 410 are slidably mounted on the mounting plate 430. A slide rail 120 extending along the second direction Y is provided on the base frame 100. The mounting plate 430 is slidably mounted on the slide rail 120 through a slider 470. The second driving member 440 drives the mounting plate 430 to slide back and forth along the slide rail 120, thereby driving all the side pressure blocks 410 to approach or move away from the battery cells on the support assembly 200, so that all the side pressure blocks 410 are pressed or detached from the side surfaces of the battery cells 600 one by one.

[0077] It is not difficult to understand that when the support block 210 drives the battery cell 600 to slide, the two sides of the battery cell 600 are respectively pressed by the two side pressure blocks 410, and with the help of the static friction between the side pressure blocks 410 and the battery cell 600, the side pressure blocks 410 press the corresponding battery cell 600 while sliding along the first direction X with the battery cell 600. In this way, the side pressure blocks 410 maintain the action of limiting the side of the battery cell 600 during the sliding process of the battery cell 600, preventing the battery cell 600 on the support block 210 from tipping toward its opposite sides, ensuring the stability of the battery cell 600 during the sliding process, and further improving the accuracy and consistency of adjusting the spacing between the battery cells 600.

[0078] Further, see Figure 8 and Fig. 9 The side pressure assembly 400 further includes a second guide column 420 extending along the first direction X, and a plurality of side pressure blocks 410 are slidably sleeved on the second guide column 420 .

[0079] Specifically, there are a plurality of second guide pillars 420 .

[0080] It is not difficult to understand that when multiple side pressure blocks 410 slide along the first direction X, the second guide column 420 provides accurate guidance for the sliding of the side pressure blocks 410, ensuring that the side pressure blocks 410 slide in a straight line, avoiding the support blocks 210 and the battery cells 600 on the support blocks 210 from shifting on both sides, and further improving the accuracy of adjusting the spacing between the battery cells 600.

[0081] In addition, see Figure 8 and Fig. 9 The side pressure assembly 400 also includes a second elastic member 450 and a second limiting column 460. The second elastic member 450 is sleeved on the second guide column 420. The second limiting column 460 is fixedly connected to the side pressure block 410 at one end away from the pushing mechanism 300. The second limiting column 460 is movably arranged along the first direction X to penetrate into the adjacent side pressure block 410 to stop and limit the adjacent side pressure block 410.

[0082] Specifically, the side pressure block 410 is a compression spring.

[0083] It can be understood that, consistent with the overall structure of the support assembly 200, in the side pressure assembly 400, when all the side pressure blocks 410 are in the initial position, the side pressure blocks 410 between adjacent side pressure blocks 410 are in a compressed and energized state, and the adjacent side pressure blocks 410 are kept at a first preset distance by the second elastic member 450 and the second limiting column 460 and the stop limiting function of the side pressure blocks 410. The second elastic member 450 also plays the role of resetting the side pressure blocks 410, preparing for the side pressure assembly 400 to adjust the cell spacing next time as a whole.

[0084] In some embodiments of the present application, see Figure 8 A plurality of protrusion structures 411 are provided on the side of the side pressing block 410 facing the battery cell 600 .

[0085] Specifically, the protruding structure 411 includes a plurality of ridges or convex bumps spaced apart and distributed on the side surface of the side pressure block 410 .

[0086] By setting the protruding structure 411, the static friction between the side pressure block 410 and the battery cell 600 can be increased, and the probability of relative slip between the side pressure block 410 and the battery cell 600 during the sliding process of the battery cell 600 can be reduced, thereby further avoiding the support block 210 and the battery cell 600 on the support block 210 from shifting along both sides, and further improving the accuracy of adjusting the spacing between the battery cells 600.

[0087] In some embodiments of the present application, see Figure 1 The battery cell spacing adjustment device of the present application further includes a material supply mechanism 500 , which is used to clamp and place a plurality of battery cells 600 on corresponding support blocks 210 .

[0088] Specifically, the incoming material mechanism 500 has a plurality of clamping members for clamping or releasing the battery cells 600. Through the arrangement of the incoming material mechanism 500, the transfer of the plurality of battery cells 600 on the production line is achieved.

[0089] In addition, an embodiment of the present application further provides a battery production device, and the battery production device includes the cell spacing adjustment device of any of the above embodiments.

[0090] The battery production equipment of the present application, since it is equipped with the above-mentioned battery cell spacing adjustment device, also has the same technical effect brought by the battery cell spacing adjustment device, that is, it can accurately make all the support blocks stacked along the first direction or distributed according to the second preset spacing under the pushing action of the pushing mechanism, so that all the corresponding battery cells on all the support blocks are distributed according to the second preset spacing. In this way, accurate adjustment of the battery cell spacing is achieved, the consistency of adjusting the battery cell spacing is improved, and the efficiency of adjusting the battery cell spacing is also improved.

[0091] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0092] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
