Description

Technical Field

[0001] The utility model relates to the field of batteries, in particular to a transporting and placing device. Background Art

[0002] Existing cylindrical battery cells have become the mainstream product in the new energy market. During their research and development process, especially during the manufacturing process of the pilot line, due to the characteristics of the shape of the cylindrical battery cells, the horizontally / vertically placed battery cells are prone to tipping over or the positive and negative poles are in contact and ignited, which is not conducive to the convenience of actual operation and safety protection. The tipped battery cells are prone to increase the time cost in the actual operation process and the safety hazard of short circuit and ignition.

[0003] The inventor has found that in the production process of the pilot line, the cylindrical battery cell transfer and placement frames used are all tight-fitting designs. No matter how they are placed, it will cause difficulties in taking them out. After the cylindrical battery cell is laser-welded, there will be excess height at the edge of the bottom cover. Under the premise of ensuring the effective melting depth of the bottom cover laser welding, the excess height is inevitable. Therefore, after the bottom cover is laser-welded and assembled, the size of the bottom cover of the cylindrical battery cell is larger than the design size of the bottom cover before welding, resulting in the incompatibility of the existing tight-fitting design of the transfer and placement frames, and the tipping of the battery cell is prone to safety hazards. On the one hand, the convenience of taking the battery cell is lacking, which increases the labor time cost, and on the other hand, the safety is reduced during the manufacturing process.

[0039] It can be understood that by providing a placement base 100 and a plurality of clamping modules 200, when the cylindrical battery cell 400 is placed downward from the first cavity 111, the cylindrical battery cell 400 squeezes the clamping module 200 and the elastic member 300 and moves toward the second cavity 112, and the elastic member 300 causes the clamping module 200 to clamp the cylindrical battery cell 400 through a reaction force, thereby controlling the relative displacement of the cylindrical battery cell 400 and preventing it from tipping over and causing safety hazards during transportation and placement; at the same time, the design of the elastic member 300 makes it convenient to take the cylindrical battery cell 400.

[0040] Please refer to Figure 2 In this embodiment, one end of the cylindrical battery cell 400 is provided with a protruding battery cell pole 410, and the other end is a flat bottom cover end.

[0043] Of course, in other embodiments, the placement base 100 is an integrally formed structure.

[0044] In this embodiment, the placement base 100 includes a base body 110; the top of the base body 110 is the loading end of the cylindrical battery cell 400, and the bottom of the base body 110 is connected to the bottom support plate 120. The base body 110 is a rectangular plate-shaped structure, and the outer wall of the base body 110 is provided with a mounting hole for connecting and fixing with the guard plate 130. Please refer to Figure 3 A plurality of hollow columnar first cavities 111 are arranged in a matrix on the base body 110 ; at least two rectangular second cavities 112 are disposed at the bottom of the base body 110 .

[0045] The reserved position of the first cavity 111 is relatively loose, and does not interfere with the placement of the cylindrical battery cell 400 when there is extra height; the diameter of the first cavity 111 is greater than the diameter of the cylindrical battery cell 400.

[0046] In this embodiment, please refer to Figure 4-Figure 5 A second column 113 is disposed in the second cavity 112 of the base body 110 , and the second column 113 is disposed opposite to the first column 220 of the clamping module 200 ; and the second column 113 is used to sleeve the second end of the elastic member 300 and abut against the first column 220 .

[0047] In this embodiment, the base body 110 extends a first extension portion 114 along the upper portion of the second cavity 112 . The first extension portion 114 is used to limit the clamping module 200 .

[0048] In this embodiment, please refer to Figure 1 , three second cavities 112 are arranged in each first cavity 111; and the three second cavities 112 are arranged at equal angles along the circumference of the first cavity 111, and the interval angle of the three second cavities 112 is 120°. Of course, in other embodiments, the number of second cavities 112 can also be two, four, etc., and the number of second cavities 112 and supporting modules can be increased according to actual usage.

[0049] In this embodiment, the placement base 100 includes a bottom support plate 120; the bottom support plate 120 is a rectangular plate structure, and a plurality of mounting holes for connecting and fixing with the base body 110 and the support plate are respectively provided on the bottom support plate 120 to avoid the first cavity 111.

[0050] In this embodiment, please refer to Figure 4 and Figure 6 The bottom support plate 120 is also provided with a plurality of reserved grooves 121, which are respectively arranged relative to the plurality of first cavities 111. The reserved grooves 121 are circular groove structures, the depth of the reserved grooves 121 is greater than the height of the pole 410 of the cylindrical battery cell 400, and the diameter of the reserved grooves 121 is smaller than the diameter of the cylindrical battery cell 400 and greater than the diameter of the pole 410.

[0051] It is understandable that the reserved groove 121 is provided on the bottom support plate 120, so that the pole 410 of the cylindrical battery cell 400 can be placed at the pole 410 end to avoid damage to the pole 410 of the cylindrical battery cell 400. Such a setting can meet the requirements of placing the cylindrical battery cell 400 in different directions, meet the convenience of taking the cylindrical battery cell 400 in different steps during the manufacturing process, and save labor time cost.

[0052] In this embodiment, the transfer and placement device 010 includes a plurality of protective plates 130 .

[0053] In this embodiment, please refer to Figure 1 and Figure 8-Figure 9 , four guard plates 130 are arranged along the edge of the base body 110; the bottoms of the four guard plates 130 are fixed to the bottom support plate 120 by screws respectively; the four guard plates 130 are provided with mounting holes and are fixed to the outer side wall of the base body 110 by screws.

[0054] It is worth mentioning that the shape and number of the guard plate 130 are specifically selected according to the shape of the base body 110. For example, if the base body 110 is circular, the guard plate 130 can be an arc plate, etc.; if the base body 110 is triangular, the number of the guard plates 130 is three.

[0055] In this embodiment, the transfer and placement device 010 includes an elastic member 300 .

[0056] In this embodiment, please refer to Figure 7 , the elastic member 300 is a spring, then the first end of the elastic member 300 is sleeved on the first column 220 of the clamping module 200, and the first end of the elastic member 300 abuts against the clamping module 200; the second end of the elastic member 300 is sleeved on the second column 113 of the base body 110, and the end of the second end of the elastic member 300 abuts against the inner wall of the base body 110.

[0057] Of course, in other embodiments, the elastic member 300 may also have an arc-shaped spring structure.

[0058] In this embodiment, the transfer and placement device 010 includes a plurality of clamping modules 200 , which are disposed in the second cavity 112 and slide along the second cavity 112 , and one end of the clamping module 200 facing the second cavity 112 abuts against the first end of the elastic member 300 .

[0059] In this embodiment, please refer to Figure 7The clamping module 200 is a rectangular block structure, and the end of the clamping module 200 that contacts the cylindrical battery cell 400 is an arc surface that fits the outer wall of the cylindrical battery cell 400. The clamping module 200 has a first groove 210 at one end facing the second cavity 112, and a first column 220 is disposed in the first groove 210. The first column 220 is used to sleeve the elastic member 300.

[0060] In this embodiment, please refer to Figure 5 and Figure 7 , the clamping module 200 extends a second extension portion 230 toward one end of the second cavity 112. It can be understood that the first extension portion 114 and the second extension portion 230 cooperate to limit the clamping module 200; when the cylindrical battery cell 400 is taken out from the first cavity 111, the elastic member 300 pushes the clamping module 200 toward the center of the first cavity 111 through the reaction force until the second extension portion 230 abuts against the first extension portion 114, thereby preventing the clamping module 200 from being separated from the second cavity 112.

[0061] Optionally, see Figure 5 and Figure 7 A guide surface 240 is provided at one end of the clamping module 200 for contacting the cylindrical battery cell 400; the guide surface 240 may be an inclined surface or an arc surface.

[0062] Optionally, see Figure 5 and Figure 7 The contact end between the clamping module 200 and the bottom support plate 120 is also provided with a sliding groove 250 for easy sliding.

[0063] The assembly and working principle of the transfer placement device 010 proposed in this embodiment are:

[0064] Please refer to 8 and Fig. 9 , turn the base body 110 upside down, assemble the clamping module 200 and the elastic member 300 and place them in the second cavity 112 reserved for the base body 110; fix the bottom support plate 120 to the base body 110; install four arc plates along the four edges of the base body 110 in sequence; it can be used directly after assembly.

[0065] When the bottom cover end of the cylindrical battery cell 400 is facing the first cavity 111 and placed downward from the first cavity 111, the cylindrical battery cell 400 squeezes the clamping module 200 along the guide surface 240, and the clamping module 200 squeezes the elastic member 300 to move toward the second cavity 112. The elastic member 300 clamps the cylindrical battery cell 400 by the reaction force, controls the relative displacement of the cylindrical battery cell 400, and prevents it from tipping over during transportation and placement to cause safety hazards; take out the cylindrical battery cell 400, and the elastic member 300 drives the clamping module 200 to reset. Accordingly, when the pole 410 end of the cylindrical battery cell 400 is facing the first cavity 111 and placed downward from the first cavity 111, the pole 410 can be accommodated in the reserved groove 121 to avoid damage to the pole 410.

[0066] After placing multiple cylindrical battery cells 400 on the transfer placement device 010, they can be transferred as a whole to the bottom cover welding process of the cylindrical battery cell 400; or the production line employees scan the code, specifically the production line employees scan the battery cell QR code at the pole 410 end of the cylindrical battery cell 400; which greatly facilitates the normal circulation of the cylindrical battery cell 400.

[0067] In summary, the transfer and placement device 010 proposed in the present invention, by providing a placement base 100 and a plurality of clamping modules 200 and an elastic member 300, when the cylindrical battery cell 400 is placed downward from the first cavity 111, the cylindrical battery cell 400 squeezes the clamping module 200 and the elastic member 300 and moves toward the second cavity 112, and the elastic member 300 causes the clamping module 200 to clamp the cylindrical battery cell 400 through a reaction force, thereby controlling the relative displacement of the cylindrical battery cell 400 and preventing it from tipping over and causing safety hazards during the transfer and placement process; the design of the elastic member 300 also makes it easier to take the cylindrical battery cell 400; at the same time, the transfer and placement device 010 is simple to assemble, and has both convenience and safety, thereby reducing the labor time cost and safety guarantee for the manufacturing process of the cylindrical battery cell 400.

[0068] Furthermore, by setting a reserved groove 121 on the bottom support plate 120, the demand for placing the cylindrical battery cell 400 in different directions is met, the damage of the pole 410 of the cylindrical battery cell 400 is avoided, the convenience of taking the cylindrical battery cell 400 in different steps during the manufacturing process is met, and the labor time cost is saved.
