Description

Technical Field

[0001] The utility model relates to the technical field of cylindrical battery production, in particular to a stackable turnover box for cylindrical batteries. Background Art

[0002] In the actual production process of cylindrical batteries, cylindrical batteries usually need to go through production processes such as shelling, bottom welding, grooving, drying, liquid injection, cap welding, sealing and cleaning; among them, the cylindrical battery production lines of some new energy battery manufacturers cannot fully realize automated production, and cylindrical batteries at the end of the previous production process need to be manually turned over to the beginning of the next production process. For example, cylindrical batteries before the caps are sealed need to be turned over, and the traditional cylindrical battery turnover method is to load the cylindrical batteries into turnover boxes in batches and then transport them.

The feeding transmission mechanism is provided with a feeding channel, the loading box mechanism is equipped with a loading box for stacking cylindrical batteries up and down, a blocking mechanism is installed on one side or above the feeding channel, the blocking mechanism includes a blocking side plate and a blocking driving cylinder for driving the blocking side plate to extend into or withdraw from the feeding channel, and a misaligned stop plate and a misaligned stop cylinder for driving the misaligned stop plate to retreat are also installed at the end of the feeding channel.

[0004] However, the technical solution disclosed in the above patent still has the following problems: although the above cylindrical battery automatic boxing structure realizes the stacking of cylindrical batteries in rows in the loading box, it cannot guarantee the transportation stability of the cylindrical batteries during the subsequent transportation of the loading box by simply placing each row of cylindrical batteries in an up-and-down staggered manner, that is, the cylindrical batteries in the loading box shake due to the bumpy transportation, which can easily cause damage to the cylindrical battery core (winding core) or the tab.

[0036] The present disclosure provides a stackable turnover box, including a plurality of unsealed cylindrical batteries. The stackable turnover box also includes a dust cover, a box body, and a plurality of magnetic parts. The box body is provided with a receiving cavity, the dust cover is located at the open end of the receiving cavity and is covered on the box body, a plurality of spacer cylinders are distributed in an array at the bottom of the receiving cavity to divide the receiving cavity into a plurality of positioning cavities, each of the cylindrical batteries is placed in a corresponding positioning cavity, and the outer peripheral wall of each of the spacer cylinders is sleeved with at least one annular elastic member, and the maximum outer contour of the annular elastic member is elastically abutted against the outer peripheral wall of the surrounding corresponding cylindrical battery. Each of the magnetic parts is embedded in the bottom of the corresponding positioning cavity.

[0037] See also Figures 1 to 7 In order to better understand the stackable turnover box 10 of the present application, the stackable turnover box 10 is further explained below:

[0038] A stackable turnover box 10 of one embodiment includes a plurality of unsealed cylindrical batteries 100. The stackable turnover box 10 also includes a dust cover 200, a box body 300, and a plurality of magnetic suction members 400. The box body 300 is provided with a receiving cavity 301, the dust cover 200 is located at the open end of the receiving cavity 301 and is covered on the box body 300, a plurality of spacing cylinders 310 are distributed in an array at the bottom of the receiving cavity 301 to separate the receiving cavity 301 into a plurality of positioning cavities 301a, each of the cylindrical batteries 100 is placed in the corresponding positioning cavity 301a, and the outer peripheral wall of each of the spacing cylinders 310 is sleeved with at least one annular elastic member 3110, and the maximum outer contour of the annular elastic member 3110 is elastically abutted against the outer peripheral wall of the surrounding corresponding cylindrical battery 100. Each of the magnetic suction members 400 is embedded in the bottom of the corresponding positioning cavity 301a.

[0039] In this embodiment, the accommodating cavity 301 is divided into a plurality of positioning cavities 301a by a plurality of spacer cylinders 310, so that each cylindrical battery 100 can be reliably placed in the corresponding positioning cavity 301a; at the same time, the outer wall of the cylindrical battery 100 is elastically abutted against the maximum outer contour of the annular elastic member 3110, which not only limits the horizontal movement freedom of the cylindrical battery 100, but also enables the annular elastic member 3110 to provide an effective elastic buffer for the cylindrical battery 100; further, a magnetic suction member 400 is embedded in the bottom of the positioning cavity 301a, and the bottom metal shell of the cylindrical battery 100 is attracted by the magnetic force of the magnetic suction member 400, so that the cylindrical battery 100 placed in the positioning cavity 301a has better transportation stability, thereby avoiding the shaking problem of the cylindrical battery 100.

[0040] Furthermore, by covering the dust cover 200 on the box body 300, the dust cover 200 can seal and shield the open end of the accommodating cavity 301, thereby preventing dust from penetrating into the interior of the cylindrical battery 100 from the unsealed end adjacent to the cap during transportation of the cylindrical battery 100, thereby effectively ensuring the product quality of the cylindrical battery 100.

[0041] It should be noted that, in this embodiment, the magnetic attraction member 400 is a magnetic metal member with magnetic attraction. The magnetic metal member is small in size and can be preset at the bottom of the positioning cavity 301a and rely on magnetic force to attract the metal steel shell of the cylindrical battery (the metal shell of the cylindrical battery).

[0042] like Figures 1 to 5 As shown, in one embodiment, the box body 300 is formed with a plurality of support legs 320, and the upper end of each of the support legs 320 is provided with a first stacking notch 3201, and at least one of the plurality of first stacking notches 3201 has a first foolproof portion 3210 disposed therein. In one embodiment, the bottom surface of the dust cover 200 is formed with a plurality of first stacking protrusions 210, and at least one of the plurality of first stacking protrusions 210 has a first foolproof hole 2101 disposed therein, and each of the first stacking protrusions 210 is plugged into the corresponding first stacking notch 3201, so that the first foolproof hole 2101 is plugged into the first foolproof portion 3210. It can be understood that the dust cover 200 is covered on the box body 300, so that each first stacking protrusion 210 is plugged into the corresponding first stacking groove 3201, and the first fool-proof hole 2101 and the first fool-proof portion 3210 are also plugged into synchronously, so as to achieve dust-proof shielding of the unsealed cylindrical battery 100 in the positioning cavity 301a by the dust cover 200.

[0043] like Figures 1 to 7As shown, in one embodiment, a plurality of second stacking protrusions 3220 are formed at the lower end of each of the supporting legs 320, and at least one of the plurality of second stacking protrusions 3220 has a second fool-proof hole 322a at its end. In one embodiment, a plurality of second stacking notches 201 are formed on the top surface of the dust cover 200, and each of the second stacking notches 201 is rectangular, circular or conical. At least one of the plurality of second stacking notches 201 has a second fool-proof portion 220 therein, and each of the second stacking protrusions 3220 is respectively plugged into the corresponding second stacking notch 201 of the dust cover 200 stacked below the box body 300, so that the second fool-proof hole 322a is plugged into the second fool-proof portion 220.

[0044] It can be understood that, first, each first stacking protrusion 210 is plugged into the corresponding first stacking slot 3201, and the first fool-proofing hole 2101 and the first fool-proofing portion 3210 are also plugged into synchronously, and then each second stacking protrusion 3220 is respectively plugged into the corresponding second stacking slot 201 of the dust cover 200 stacked under the box body 300, and the second fool-proofing hole 322a and the second fool-proofing portion 220 are also plugged into synchronously, and finally the dust cover 200 is covered on the first box body 300, and the second box body 300 is stacked on the dust cover 200, so that the box body 300 and the dust cover 200 are reciprocatingly and cross-stacked in sequence. Specifically, it not only ensures that the unsealed cylindrical battery 100 has good transportation stability in the positioning cavity 301a, but also prevents dust from penetrating into the interior of the unsealed cylindrical battery 100, and at the same time, it can maximize the stacking turnover of the unsealed cylindrical battery 100, thereby effectively improving the transportation efficiency of the unsealed cylindrical battery 100; more specifically, by plugging the first fool-proof hole 2101 with the first fool-proof part 3210, and the second fool-proof hole 322a with the second fool-proof part 220, it can effectively prevent the user from mistakenly stacking the box body 300 and the dust cover 200 in reverse when stacking the box body 300 and the dust cover 200, thereby causing the placement sequence of batches of cylindrical batteries 100 in the accommodating cavity 301 to be reversed, which is also convenient for the user to record and trace the source later.

[0045] like Figures 1 to 3As shown, in one embodiment, the bottom surface of the dust cover 200 is formed with a first longitudinal shielding portion 230, a second longitudinal shielding portion 240, a first transverse shielding portion 250 and a second transverse shielding portion 260. A first opening 302 and a second opening 303 are respectively formed between two groups of the support legs 320 adjacent to each other in the longitudinal direction of the box body 300, and a third opening 304 and a fourth opening 305 are respectively formed between two groups of the support legs 320 adjacent to each other in the transverse direction of the box body 300; the first longitudinal shielding portion 230 is arranged at the first opening 302, the second longitudinal shielding portion 240 is arranged at the second opening 303, the first transverse shielding portion 250 is arranged at the third opening 304, and the second transverse shielding portion 260 is arranged at the fourth opening 305.

[0046] It can be understood that when the dust cover 200 is covered on the box body 300, the first longitudinal shielding portion 230 and the first opening 302, the second longitudinal shielding portion 240 and the second opening 303, the first transverse shielding portion 250 and the third opening 304, and the second transverse shielding portion 260 and the fourth opening 305 respectively form structural complementary engagement, effectively isolating dust from penetrating into the accommodating cavity 301, ensuring that the product quality of the unsealed cylindrical battery 100 is not affected.

[0047] like Figures 1 to 3 As shown, in one embodiment, the box body 300 is an integrally molded structure. In one embodiment, the dust cover 200 is a transparent plastic injection molded structure. It is understandable that the box body 300 needs to bear the weight of multiple cylindrical batteries 100, and the integrally molded structure gives the box body 300 better structural strength; it is understandable that in this embodiment, the box body 300 is a plastic integrally injection molded structure. Among them, the dust cover 200 is a transparent plastic injection molded structure, so that the user can observe the placement of the cylindrical battery 100 in the positioning cavity 301a.

[0048] like Figure 1 As shown, in one embodiment, a first U-shaped grip 330 and a second U-shaped grip 340 are formed on both sides of the box body 300, and the first U-shaped grip 330 and the second U-shaped grip 340 are detachably connected to the box body 300. It can be understood that in this embodiment, the first U-shaped grip 330 and the second U-shaped grip 340 are detachably connected to the box body 300, specifically, they can be screwed or snap-fitted, to meet the user's needs for disassembly according to actual needs, such as saving the space occupancy rate of the box body 300 after disassembling the first U-shaped grip 330 and the second U-shaped grip 340. In other embodiments, the first U-shaped grip 330 and the second U-shaped grip 340 are integrally formed structures with the box body 300.

[0049] like Figure 1 , Figure 2 and Figure 6 As shown, in one embodiment, the outer peripheral wall of each of the spacing cylinders 310 is surrounded by an annular tightening groove 3101, each of the annular elastic members 3110 is fixedly installed in the corresponding annular tightening groove 3101, and a guide portion is formed at the end of each of the spacing cylinders 310. It can be understood that the surface of the guide portion has no vertical angle design to ensure the smoothness of the cylindrical battery 100 being placed in the positioning cavity 301a; wherein, in this embodiment, the annular elastic member 3110 is an elastic rubber ring, specifically, the annular tightening groove 3101 is designed to imitate the elastic rubber ring, so that the elastic rubber ring can be reliably fixedly installed in the annular tightening groove 3101, thereby providing an elastic buffering effect for the cylindrical battery 100 and avoiding the shaking problem of the cylindrical battery 100.

[0050] Compared with the prior art, the utility model has at least the following advantages:

[0051] 1. The accommodating cavity is divided into multiple positioning cavities by multiple spacer cylinders, so that each cylindrical battery can be reliably placed in the corresponding positioning cavity; at the same time, the outer wall of the cylindrical battery is elastically abutted against the maximum outer contour of the annular elastic member, which not only limits the horizontal movement freedom of the cylindrical battery, but also the annular elastic member can provide effective elastic buffering for the cylindrical battery; further, a magnetic suction member is embedded in the bottom of the positioning cavity, and the bottom metal shell of the cylindrical battery is sucked by the magnetic force of the magnetic suction member, so that the cylindrical battery placed in the positioning cavity has better transportation stability, thereby avoiding the shaking problem of the cylindrical battery.

[0052] 2. By installing the dust cover on the box body, the dust cover can seal and shield the open end of the accommodating cavity, thereby preventing dust from penetrating into the interior of the cylindrical battery from the unsealed end adjacent to the cap during transportation of the cylindrical battery, thereby effectively ensuring the product quality of the cylindrical battery.

[0053] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
