Description

Technical Field

[0001] The utility model relates to the technical field of soft-pack battery testing, in particular to a soft-pack battery transfer box. Background Art

[0002] Soft-pack batteries refer to batteries with a roll core wrapped with aluminum-plastic film. When a safety hazard occurs, they will only bulge and crack, and will not explode. Therefore, soft-pack batteries are widely used.

[0003] The manufacturing process of soft pack batteries is as follows: homogenization, coating, rolling, cutting, lamination / winding, packaging, liquid injection, pre-sealing, static, formation, secondary packaging, testing and sorting. Figure 4 The soft-pack battery 20 shown is heat-sealed at one end away from the battery cell 21, so that a sealed air storage bag is formed in the aluminum-plastic film. Then, during the static process, the electrolyte fully infiltrates the battery cell. Then, in the formation process, the battery is charged for the first time to form a stable solid electrolyte interface (SEI) film inside it. Then, in the secondary packaging process, the air in the aforementioned air storage bag is extracted and the aluminum-plastic film is heat-sealed again near the battery cell 21, so that a sealed space is formed in the battery cell 21.

[0004] With the development of automation technology, the automatic production of soft-pack batteries is becoming more and more popular. In the above-mentioned pre-sealing, standing, formation, secondary packaging, testing and other processes of the soft-pack batteries, the soft-pack batteries 20 need to be transferred to the corresponding workstations in sequence for processing. However, for the soft-pack batteries used in smart wearable devices, due to their small size, the battery tabs 22 are even thinner, so the soft-pack batteries are prone to deformation of the tabs 22 during the transfer process. Once the tabs 22 are deformed, since the soft-pack batteries are automatically fed on automatic production equipment, it will lead to the inability to accurately test the soft-pack batteries 20 in processes such as testing. In order to avoid deformation of the tabs 22 of the soft-pack batteries 20, a soft-pack battery transfer box capable of simultaneously transferring multiple soft-pack batteries is proposed in this application. Utility Model Content

[0005] The purpose of the utility model is to overcome the deficiencies in the prior art and provide a soft-pack battery transfer box that can prevent the tabs of the soft-pack battery from being deformed during the transfer process.

[0006] The purpose of this utility model is achieved through the following technical solutions:

[0007] A soft pack battery transfer box, comprising:

[0008] The box body is provided with a plurality of material storage grooves distributed vertically and horizontally, an air avoidance groove is provided on one side of the material storage groove, and a positioning groove is provided on the bottom wall of the material storage groove. The positioning groove is used to accommodate the battery cell of the soft-pack battery so that the pole ear is located in the air avoidance groove and the pole ear abuts against the bottom wall of the air avoidance groove.

[0009] Optionally, a shielding groove is provided on the inner bottom wall of the material placement groove at one end away from the locking groove, so that a shielding protrusion is correspondingly formed on the side surface of the box body away from the material placement groove.

[0010] Optionally, four positioning circular grooves are further provided on the box body, so that corresponding positioning protrusions are formed on a side surface of the box body away from the positioning circular grooves.

[0011] Optionally, the box body is further provided with a plurality of material taking slots, and each material placing slot located on the same straight line on the box body is communicated with one of the material taking slots.

[0012] Optionally, a clamping portion is provided on the inner side wall of the material placement groove at a position away from the clamping groove.

[0013] Optionally, two material-clamping parts are provided, and the two material-clamping parts are respectively located on two inner side walls of the material-loading groove that are distributed opposite to each other.

[0014] Optionally, a reinforcement ring is provided on the edge of the box body.

[0015] Optionally, the reinforcement ring and the box body are an integrally formed structure.

[0016] Optionally, the material trough is a rectangular trough structure.

[0017] Optionally, a ventilation groove is provided at each of the four corners of the material trough.

[0018] Compared with the prior art, the present invention has at least the following advantages:

[0019] The utility model relates to a soft-pack battery transfer box, comprising a box body, on which a plurality of material storage slots distributed vertically and horizontally are provided, a void groove is provided on one side of the material storage slot, and a positioning slot is provided on the bottom wall of the material storage slot. The positioning slot is used to accommodate the battery cell of the soft-pack battery so that the tab is located in the void groove and the tab abuts against the bottom wall of the void groove. In this way, when the soft-pack battery is placed in the material storage slot, one side of the battery cell is placed in the positioning slot so that the tab is located in the void groove and the tab abuts against the inner bottom wall of the void groove. Furthermore, after each material storage slot in the box body is filled with soft-pack batteries, the multiple boxes can be stacked and stacked. At this time, since the soft-pack batteries occupy a position in the material storage slot, a gap will be maintained between any two box bodies, so that the tab in the void groove will not be squeezed, and since the tab is in contact with the bottom wall of the void groove for protection, the soft-pack battery will not be deformed by force when transferred between the various processes.

[0027] In order to facilitate the understanding of the present invention, the present invention will be described in more detail below with reference to the accompanying drawings, in which preferred embodiments of the present invention are shown.

[0028] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do 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 invention.

[0029] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined.

[0030] In the embodiments of the present invention, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection; direct connection, indirect connection through an intermediate medium; internal communication between two components, or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the embodiments of the present invention based on specific circumstances.

[0031] like Figure 1 As shown, a soft-pack battery transfer box 10 includes a box body 100, and a plurality of material storage grooves 110 distributed vertically and horizontally are opened on the box body 100. An air avoidance groove 120 is opened on one side of the material storage groove 110, and a locking groove 130 is opened on the bottom wall of the material storage groove 110. The locking groove 130 is used to accommodate the battery cell 21 of the soft-pack battery 20 so that the tab 22 is located in the air avoidance groove 120, and the tab 22 abuts against the bottom wall of the air avoidance groove 120.

[0032] It should be noted that a plurality of material loading grooves 110 are provided on one side surface of the box body 100, wherein each material loading groove 110 is arranged at equal intervals in the longitudinal and transverse directions. The material loading groove 110 is used to accommodate the soft-pack battery 20. Furthermore, an air-avoiding groove 120 is provided on an inner side wall of the material loading groove 110, and a positioning groove 130 is provided on the inner bottom wall of the material loading groove 110, wherein the connecting line between the positioning groove 130 and the air-avoiding groove 120 is perpendicular to the extension line of the length direction of the material loading groove 110. In this way, when the soft-pack battery 20 is placed in the material loading groove 110, one side of the battery cell 21 is placed in the positioning groove 130, so that the tab 22 is located in the air-avoiding groove 120, and the tab 22 is in contact with the inner bottom wall of the air-avoiding groove 120. Furthermore, after each loading groove 110 in the box body 100 is filled with soft-pack batteries 20, the multiple box bodies 100 can be stacked and placed. At this time, since the soft-pack batteries 20 occupy a position in the loading groove 110, there will be a gap between any two box bodies 100, so the tabs 22 located in the air-avoidance groove 120 will not be squeezed at all, and since the tabs 22 are in contact with the bottom wall of the air-avoidance groove 120 for protection, the soft-pack batteries 20 will not be deformed by force when transferred between the various processes.

[0033] like Figure 1 and Figure 2 As shown, in one embodiment, a shielding groove 141 is formed on the inner bottom wall of the material loading groove 110 away from the locking groove 130 , so that a shielding protrusion 142 is correspondingly formed on the side surface of the box body 100 away from the material loading groove 110 .

[0034] It should be noted that the shielding grooves 141 and shielding protrusions 142 on the same box body 100 are in a corresponding and aligned structural relationship. In this way, when two box bodies 100 are stacked on each other, the soft-pack battery 20 is placed in the material storage groove 110 of the box body 100 located below. The aluminum-plastic bag of the soft-pack battery 20 will cover the shielding groove 141, so the shielding protrusion 142 of the box body 100 located above cannot sink into the shielding groove 141 of the box body 100 located below. Therefore, when multiple box bodies 100 are stacked, a certain gap is maintained between any two adjacent box bodies 100, making it easier for the equipment to pick up and place the entire box body 100, thereby realizing the transfer of multiple soft-pack batteries 20.

[0035] like Figure 1 and Figure 2 As shown, in one embodiment, four positioning circular grooves 151 are further formed on the box body 100 , so that a positioning protrusion 152 is correspondingly formed on a side surface of the box body 100 away from the positioning circular grooves 151 .

[0036] It should be noted that, in this manner, a positioning groove 151 is provided at each of the four corners of one side of the box body 100, and a corresponding positioning protrusion 152 is provided on the other side of the box body 100, so that each positioning groove 151 is aligned with each positioning protrusion 152. In this way, when multiple boxes 100 are stacked, the positioning grooves 151 and the positioning protrusions 152 can ensure that the boxes 100 are stacked neatly, effectively improving the stability of the stacked boxes 100.

[0037] like Figure 3 As shown, in one embodiment, a plurality of material taking slots 160 are further provided on the box body 100 , and each of the material placing slots 110 located on the same straight line on the box body 100 is communicated with one of the material taking slots 160 .

[0038] It should be noted that when soft-pack batteries 20 are placed in each of the material slots 110 of the box body 100, the production equipment mainly relies on suction cups to pick up and place the soft-pack batteries 20. However, for occasions such as semi-automated equipment that require manual picking up and placing of soft-pack batteries 20, in order to facilitate workers to pick up and place the soft-pack batteries 20, a material extraction slot 160 is also provided on the box body 100. For example, in the example given in this application, the box body 100 has a structure with four material slots 110 in the horizontal direction and ten in the vertical direction, for a total of forty material slots 110. Four material extraction slots 160 are provided along the longitudinal direction of the box body 100, so that the ten material slots 110 in each column are connected to one material extraction slot 160. In this way, through the material extraction slot 160, even if the soft-pack battery 20 is small in size, workers can stably place the soft-pack battery 20 into the material slot 110 or take it out from the material slot 110. Furthermore, it should be noted that the present embodiment illustrates a configuration in which the box body 100 has four horizontal slots and ten vertical slots, for a total of forty slots 110. This is merely for the purpose of clarifying the structure and function of the material extraction slot 160 and should not be construed as limiting the number of slots 110. Rather, the number of slots 110 can be arbitrarily set based on practical needs, as long as the slots 110 are arranged in a straight line both horizontally and vertically.

[0039] like Figure 1 and Figure 3 As shown, in one embodiment, a clamping portion 170 is provided on the inner side wall of the material placement groove 110 at a position away from the clamping groove 130 .

[0040] It should be noted that in order to improve the stability of the soft-pack battery 20 in the storage tank 110 and reduce the possibility of the soft-pack battery 20 accidentally falling out of the storage tank 110, a clamping portion 170 is provided on the inner side wall of the storage tank 110, wherein the clamping portion 170 is located at a position away from the clamping groove 130. In this way, when the soft-pack battery 20 is placed in the storage tank 110, the clamping portion 170 will clamp the part of the aluminum-plastic bag away from the battery cell 21, avoiding squeezing and deformation of the battery cell 21 and the tab 22. It should be noted that since the aluminum-plastic bag needs to be removed in subsequent processes, even if the aluminum-plastic bag is squeezed and deformed by the clamping portion 170, it will not affect the appearance of the soft-pack battery 20.

[0041] In one embodiment, two material-engaging portions 170 are provided, and the two material-engaging portions 170 are respectively located on two inner side walls of the material-setting groove 110 that face each other.

[0042] It should be noted that the two clamping parts 170 are distributed towards each other, and the minimum distance between the two clamping parts 170 is smaller than the width of the aluminum-plastic bag. Therefore, the two clamping parts 170 can clamp the aluminum-plastic bag reliably and stably.

[0043] like Figure 2 As shown, in one embodiment, a reinforcement ring 200 is provided on the edge of the box body 100 .

[0044] It should be noted that to enhance the deformation resistance of the surface of the box body 100, a reinforcement ring 200 is provided on the edge of the box body 100. The reinforcement ring 200 extends from the front to the back of the box body 100, that is, the extension direction of the reinforcement ring 200 is perpendicular to the surface of the box body 100. In this way, the reinforcement ring 200 and the box body 100 form a three-dimensional structure. Even if the thickness of the box body 100 is set to 1mm to reduce weight, the structural strength of the box body 100 is ensured and its deformation resistance is improved. Furthermore, in one embodiment, the reinforcement ring 200 and the box body 100 are integrally molded. This improves the structural strength between the reinforcement ring 200 and the box body 100.

[0045] In one embodiment, the material storage tank 110 is a rectangular tank structure, so that the material storage tank 110 can properly accommodate the soft-pack battery 20.

[0046] like Figure 1 and Figure 3 As shown, a vent slot 180 is provided at each of the four corners of the trough 110. It should be noted that when multiple empty boxes 100 are stacked, negative pressure will exist between any two adjacent boxes 100, making it difficult to open them. Therefore, to facilitate the separation of any two adjacent boxes 100, a vent slot 180 is provided at each of the four corners of the trough 110. This accelerates the flow of air, allowing the stacked boxes 100 to be quickly separated.

[0047] The above-mentioned embodiments only express several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. Unless otherwise specifically defined, the installation / fixing / setting mentioned in the present invention can be understood to include but not be limited to locking and fixing with screws / screws and welding. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all fall within the scope of protection of the present invention. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
