Description

TECHNICAL FIELD

[0001] The utility model relates to new energy technology field, concretely relates to a polymer soft package battery sorting and shaping frock. BACKGROUND

[0002] Lithium ion battery has the advantages of high specific energy, multiple cycle times, long storage time, etc., among which, lithium ion soft package battery is more and more applied in portable mobile device field due to the advantages of large capacity, good safety performance, small volume, flexible size design, etc.

[0003] The polymer soft package battery is a battery using aluminum plastic packaging film as packaging material, mainly including an electric core, a positive electrode tab and a negative electrode tab respectively electrically connected to the electric core, and an aluminum plastic film (the aluminum plastic film is a three-layer composite layer, from outside to inside, ON / AL / CPP (outer nylon layer / intermediate aluminum foil layer / inner heat sealing layer)).

[0004] The soft package battery needs to be tested and sorted after production, the good products sorted are shipped, the poor products sorted are graded, and then treated according to actual conditions. In the prior art, the sorting of the soft package battery is completed by an automatic code scanning sorting machine for full-automatic sorting operation, which can greatly reduce labor cost and time cost and improve sorting efficiency. The existing sorting machine usually includes a transfer clamp, the soft package battery needs to be transferred to a suction box through the transfer clamp, the transfer clamp has a clamp groove for placing the soft package battery, the suction box has a suction box groove for accommodating the soft package battery, and the clamp groove and the suction box groove are one-to-one corresponding. However, the size of the clamp groove of the existing transfer clamp is fixed and larger than the size of the soft package battery, that is, the position of the soft package battery in the clamp groove is not fixed, and the soft package battery is prone to deformation due to its characteristics, resulting in irregular size. When the soft package battery is transferred into the suction box groove of the suction box, the battery may be offset, resulting in that the soft package battery cannot be completely placed in the suction box groove when being transferred into the suction box, that is, part of the soft package battery may be exposed outside the suction box groove. Therefore, when a full suction box is full of soft package batteries, the mechanical hand grasps the empty suction box for stacking, and because the soft package battery is not placed in the suction box groove when being transferred into the suction box, the suction box of the upper layer may press the soft package battery not placed in the suction box groove of the lower layer after stacking, thereby causing the soft package battery to be damaged and become a poor product, and even causing a safety risk. Therefore, the utility model is thus derived. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0033] To make the objectives, technical solutions and advantages of the present application clearer, further detailed description will be made to the present application with reference to the embodiments and the accompanying drawings. It should be understood that the description is only exemplary and is not intended to limit the scope of the present application. In addition, in the following description, the description of the known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application.

[0034] Referring to Figures 1 to 9 , the polymer soft package battery sorting and shaping tool of the present application embodiment comprises a base 10 and a shaping assembly 20. The base 10 comprises a base plate 11, a bottom plate 12 and two support plates 13. The base plate 11 is a horizontally placed rectangular plate as shown in Figure 1 or Figure 9 .

That is, the bottom plate 12 and the base plate 11 are vertically arranged, and the length of the bottom plate 12 is slightly longer than the long side of the base plate 11. The two support plates 13 are vertically arranged at the bottom of the two wide sides of the base plate 11, i.e. Figure 1 . Any of the support plates 13 can be implemented as an inclined surface facing away from the side connected to the base plate 11. For the base plate 11, a plurality of support surfaces 111 are formed on the front surface, i.e. Figure 9 the upper surface as shown in Figure 9In the embodiment shown in FIG. 1, each support surface 111 is provided with at least one first shaping groove 112 extending along the length direction of the substrate 11 and at least one second shaping groove 113 extending along the width direction of the substrate 11. Figure 9 In the embodiment shown in FIG. 1, each support surface 111 is provided with at least one first shaping groove 112 extending along the length direction of the substrate 11 and at least one second shaping groove 113 extending along the width direction of the substrate 11. Figure 1 In the embodiment shown in FIG. 1, each support surface 111 is provided with at least one first shaping groove 112 extending along the length direction of the substrate 11 and at least one second shaping groove 113 extending along the width direction of the substrate 11. Figure 9 In the embodiment shown in FIG. 1, each support surface 111 is provided with at least one first shaping groove 112 extending along the length direction of the substrate 11 and at least one second shaping groove 113 extending along the width direction of the substrate 11. Figure 9 In the embodiment shown in FIG. 1, each support surface 111 is provided with at least one first shaping groove 112 extending along the length direction of the substrate 11 and at least one second shaping groove 113 extending along the width direction of the substrate 11.

[0035] In this embodiment, the shaping assembly 20 simultaneously shapes the long side and the wide side of the soft package battery, so that the shaped soft package battery is a rectangle. As for the structure of the shaping assembly 20, in this embodiment, each support surface 111 is provided with a width shaping member 21 and a length shaping member 22 for shaping the long side and the wide side of the soft package battery on the support surface 111. The width shaping member 21 moves along the length direction of the base plate 11, i.e. along the first shaping groove 112, to extrude and shape the long side of the soft package battery, and the length shaping member 22 moves along the width direction of the base plate 11, i.e. along the second shaping groove 113, to extrude and shape the wide side of the soft package battery. Each width shaping member 21 and its corresponding length shaping member 22 define a square shaping area 110 with variable size. More specifically, the width shaping member 21 comprises a first movable shaping piece 211 and a first fixed shaping piece 212, and the length shaping member 22 comprises a second movable shaping piece and a second fixed shaping piece. Further, as shown in FIG. 1, the first movable shaping piece 211 and the second movable shaping piece are connected by a connecting rod 213, and the first fixed shaping piece 212 and the second fixed shaping piece are connected by a connecting rod 214. Figure 1 and Figure 7As shown, the first fixed shaping member 212 comprises a first fixed plate and a first fixing member (not shown). The first fixed plate comprises a first plate body 2121 and two first extension parts 2122 which are preferably integrally formed at two ends of the first plate body 2121. The first plate body 2121 is a long strip-shaped block extending along the width direction of the base plate 11, and the two first extension parts 2122 are both square-shaped blocks extending vertically outward relative to the first plate body 2121 and in the same or opposite direction, i.e., the first fixed plate is in a U-shaped or Z-shaped form. In this embodiment, the first fixed plate corresponding to the side of the second shaping driving member 222 which is specifically the second clamping block 2223 is in a Z-shaped form, and the rest of the first fixed plates are in a U-shaped form, which is designed to avoid interference between the first extension part 2122 and the movement of the second clamping block 2223. The two first extension parts 2122 are provided to be fixedly connected with the base plate 11, and in the preferred embodiment, the two first extension parts 2122 are fixed with the base plate 11 by first fasteners (not shown) such as bolts, i.e., the first extension part 2122 has a first connecting hole (not labeled) penetrating through its thickness, and the base plate 11 has a corresponding second connecting hole (not labeled), and the first fastener is arranged in the first connecting hole and the second connecting hole to connect the first fixed plate with the base plate 11. As an alternative embodiment, the two first extension parts 2122 do not have the first connecting hole, but are directly welded or bonded with the base plate 11. In this embodiment, the thickness of the first extension part 2122 is greater than the thickness of the first plate body 2121, and the bottom surface of the first extension part 2122 at least partially protrudes from the bottom surface of the first plate body 2121, and correspondingly, the base plate 11 has two grooves (not shown) at the two ends in the width direction, which are downwardly recessed and extend along the length direction of the base plate 11 and cooperate with the first extension part 2122.

[0036] As shown in Figures 2 to 4 and Figure 8 , the first movable shaping member 211 comprises a first movable block 2111, a first movable plate 2112 and a first shaping driving member 213. The first movable block 2111 is slidably arranged in the first shaping groove 112 on each support surface 111, and the first movable plate 2112 is connected to each first movable block 2111 and opposite to the first fixed plate on one side of the support surface 111. The first shaping driving member 213 drives the first movable block 2111 to push the first movable plate 2112 to move towards or away from the first fixed plate to adjust the distance between them, which corresponds to the width of the soft-pack battery, i.e., to achieve width adjustment. In this embodiment, the first shaping driving member 213 is arranged on the back surface of the base plate 11, i.e., the bottom surface as shown in Figure 1 , or the top surface as shown in Figure 2the front face. The preferred embodiment of the present application is that all the first movable blocks 211 are driven by the same first shaping driving member 213 to move synchronously, that is, the first movable blocks 2112 on all the support faces 111 move synchronously in the same direction to achieve shaping. This design can reduce the number of first shaping driving members 213, reduce costs, and also improve shaping efficiency. That is, the first shaping driving member 213 is connected to all the first movable blocks 2111 through a first sliding plate 214 extending along the length direction of the base plate 11. As shown in Figure 8 any first movable block 2112 includes a second plate body 21121 extending along the width direction of the base plate 11 and a second extension 21122 integrally formed at one end of the second plate body 21121, that is, the first movable block 2112 is in L shape. The second extension 21122 extends perpendicularly outward relative to the second plate body 21121. In the present application, the length of the second plate body 21121 is less than the length of the first plate body 2121 of the corresponding first fixed block, and the second plate body 21121 corresponds to one of the first extensions 2122 of the corresponding first fixed block, and the two together constitute a second fixed shaping member. For the first shaping driving member 213, as shown in Figure 3 and Figure 4 a first cylinder 2131, a first push plate 2132, and a clamping block. The first cylinder 2131 is fixed at one end (exemplarily the right end in the figure) of the first sliding plate 214, and the driving end of the first cylinder 2131 faces away from the other end, that is, the driving end of the first cylinder 2131 faces the right end as shown in Figure 3 The first push plate 2132 is fixed to the driving end of the first cylinder 2131, and the first push plate 2132 can be an L-shaped plate. The first clamping block 2133 is slidably arranged on the front face of the base plate 11 and is fixedly connected to the first push plate 2132 through a second fastener (not shown). Further, a first sliding block 215 is arranged at the bottom of the first sliding plate 214, and the first sliding block 215 is slidably connected to a guide sliding rail 216 fixed to the bottom plate 12 of the base 10. The extension direction of the guide sliding rail 216 is along the length direction of the bottom plate 12, that is, the length direction of the base plate 11. Correspondingly, a clamping movable slot 114 extending along the length direction of the base plate 11, that is, the moving direction of the first movable block 2112 is formed in the base plate 11. In the present application, as exemplarily shown in Figure 9 two clamping movable slots 114 are arranged between the two first shaping slots 112 and are oppositely spaced. One end of the second fastener is fixedly connected to the first push plate 2132, and the other end is fixedly connected to the first clamping block 2133 after passing through the clamping movable slot 114. In operation, the first cylinder 2131 is retracted to the left to drive the first push plate 2132 to move to the left and push against Figure 1The first movable plate 2112 at the left end of the middle is moved towards the first fixed plate on the side of its corresponding support surface 111, thereby shaping the long side of the soft pack battery on the support surface 111 and achieving the width determination. At the same time, the first sliding plate 214 moves to the left and drives the first sliding block 215 to move to the left along the guide sliding rail 216, thereby driving all the other first movable plates 2112 to move towards the first fixed plate on the side of the corresponding support surface 111, thereby shaping the long side of the soft pack battery on the corresponding support surface 111 and achieving the width determination. That is, the first movable plate 2112 and the first fixed plate are pressed against the long side of the soft pack battery, thereby shaping the long side and determining the width of the soft pack battery. It should be noted that, in this embodiment, two first shaping grooves 112 are preferably arranged at each support surface 111, and the first movable block 2111 is preferably in the shape of a U. The first movable block 2111 and the first movable plate 2112 can be connected by fasteners (not shown) such as bolts, or can be connected by welding or adhesion, and are preferably connected by fasteners. As an alternative embodiment, the number of first shaping grooves 112 at each support surface 111 can be one, and the corresponding first movable block 2111 is in the shape of a straight line.

[0037] For the second movable shaping member, it includes a second movable block and a second shaping driving member 222. In this embodiment, as shown in Figure 1 , one end of the second movable block is connected to the second shaping driving member 222, and the other end at least partially protrudes out of the second shaping groove 113, specifically the front surface of the base plate 11, and is pressed against the wide side of the soft pack battery to shape and determine the length of the soft pack battery. Similarly, preferably, since the number of second shaping grooves 113 at each support surface 111 in this embodiment is two, the second movable block is preferably in the shape of a U. Similarly, in this embodiment, preferably, all the second movable blocks are driven to move synchronously by the same second shaping driving member 222. Specifically, all the second movable blocks are connected to the second shaping driving member 222 by a second sliding plate 223 extending along the length direction of the base plate 11. This can reduce the cost and improve the efficiency. More specifically, as shown in Figure 5 and Figure 6As shown, the second shaping driving member 222 comprises a second cylinder 2221, a second push plate 2222, a second shaping groove 113 and a second clamping block 2223. The second cylinder 2221 is fixed on the middle position of the second sliding plate 223, preferably the side of the second sliding plate 223 facing away from the base plate 11, so that the force on both sides is balanced. The second push plate 2222 is an L-shaped plate and is fixed on the driving end of the second cylinder 2221. The other end of the second push plate 2222 is fixedly connected with the second clamping block 2223 sliding on the front surface of the base plate 11 through a third fastener (not shown) such as a bolt. In this embodiment, the distance between the two second shaping grooves 113 is small, and the third fastener directly penetrates the two second shaping grooves 113. When the second cylinder 2221 retracts, the second clamping block 2223 is pushed to move towards the second movable block and push the second movable block to move towards the second fixed shaping member, so as to fix the length and press the wide side of the soft package battery. Since all the second movable blocks are connected with the second sliding plate 223, the remaining second movable blocks are also driven synchronously to shape and fix the length of the soft package battery on the respective support surface 111. In order to ensure the straightness of the movement and the straightness of the shaped side, the second shaping driving member 222 further comprises two second sliding blocks 224 fixed on both ends of the second sliding plate 223. A guide shaft 225 extending in the width direction of the base plate 11 is arranged in the middle of each second sliding block 224. One end of any guide shaft 225 is fixed on the bottom plate 12, and the other end is fixedly connected with the back surface of the base plate 11 through a fixed block 226.

[0038] For the first clamping block 2133 and the second clamping block 2223, they are both square plates.

[0039] It should be noted that in this embodiment, the length shaping member 22 and the width shaping member 21 determine the length and width of the shaped soft package battery by controlling the extension stroke, i.e. length fixing and width fixing.

[0040] In a preferred embodiment of this embodiment, a film (not shown) is also laid on each support surface 111 to protect the soft package battery and avoid direct friction between the soft package battery and the front surface of the base plate 11 during extrusion and shaping movement, thereby preventing wear.
