[0002] Soft-pack batteries, which are lithium-ion batteries encapsulated using aluminum-plastic film, have significant advantages such as light weight, high energy density, and low internal resistance, and are therefore widely used in many fields such as consumer electronics and electric vehicles. After the aluminum-plastic film is stamped into shape using a stamping die and the casing process is completed, the stamped battery casing needs to be placed in a specific mold and trimmed according to the mold specifications.

[0003] However, in traditional battery casing trimming operations, frequent manual adjustments to the mold position are often required to ensure that the trimming cutter can fully cut all four sides of the battery casing that extend beyond the mold. This method not only consumes a lot of manpower and time but is also extremely inconvenient, significantly reducing production efficiency.

[0004] Therefore, it is necessary to provide a pouch battery trimming device to solve the above-mentioned technical problems. Utility Model Content

[0005] The purpose of this invention is to provide a trimming device for soft-pack batteries to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A pouch battery trimming device, comprising:

[0008] The base has a blade holder on its top. The blade holder has transverse blades on its front and rear sides and longitudinal blades on both sides. A fixed frame is fixedly installed on the rear side of the top of the base. An electric telescopic rod is fixedly installed on the top of the fixed frame. The drive end of the electric telescopic rod passes through the fixed frame and extends to the top of the base. An upper mold is fixedly installed on the drive end of the electric telescopic rod.

[0009] The base is fixedly installed with symmetrically distributed limiting telescopic rods. The telescopic end of the limiting telescopic rod is fixedly installed with a lower mold that matches the position of the upper mold. A spring is sleeved on the outer wall of the limiting telescopic rod.

[0010] Preferably, an auxiliary blade is fixedly installed at the center of the outer surface of both longitudinal blades.

[0011] Preferably, the tool holder includes a U-shaped frame and a movable plate, with the U-shaped frame fixedly installed on the top of the base and the movable plate movably disposed at the front opening of the U-shaped frame.

[0012] Preferably, a slide rail is provided on the front side of the bottom of the base, a lead screw is rotatably installed inside the slide rail, a servo motor is fixedly installed on the front of the base, and the drive end of the servo motor passes through the base and extends into the interior of the slide rail and is fixedly connected to the front end of the lead screw. An adjustment block is sleeved on the outer wall of the lead screw, and the adjustment block is slidably installed on the slide rail. The top of the adjustment block is fixedly connected to the bottom of the movable plate.

[0013] Preferably, the two longitudinal blades are fixedly installed on both sides of the top of the U-shaped frame by bolts, one transverse blade is fixedly installed on the rear side of the top of the U-shaped frame by bolts, and the other transverse blade is fixedly installed on the top of the movable plate by bolts.

[0014] Preferably, the adjusting block has a threaded hole that matches the lead screw, and the adjusting block is threadedly connected to the lead screw through the threaded hole.

The fixing frame is provided with sliding holes corresponding to the position and number of stabilizing rods, and the fixing frame is slidably connected to the stabilizing rods through the sliding holes.

[0017] Preferably, both the transverse blade and the longitudinal blade are in sliding contact with the outer surface of the lower mold.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] 1. This utility model utilizes a base, a blade holder, a transverse blade, a longitudinal blade, a lower mold, an upper mold, a fixed frame, and an electric telescopic rod. By employing the movable characteristics of the mold and the fixed positions of the transverse and longitudinal blades, the equipment can simultaneously cut and trim the four sides of the battery casing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figures 1-4 One embodiment provided by this utility model:

[0029] A pouch battery trimming device, comprising:

[0030] A base 1 is provided with a tool holder 3 on its top. A transverse blade 4 is provided on the front and rear sides of the top of the tool holder 3. A longitudinal blade 5 is provided on both sides of the top of the tool holder 3. A fixed frame 9 is fixedly installed on the rear side of the top of the base 1. An electric telescopic rod 11 is fixedly installed on the top of the fixed frame 9. The drive end of the electric telescopic rod 11 passes through the fixed frame 9 and extends to the top of the base 1. An upper mold 8 is fixedly installed on the drive end of the electric telescopic rod 11.

[0031] A symmetrically distributed limiting telescopic rod 15 is fixedly installed on the top of the base 1. A lower mold 7 that matches the position of the upper mold 8 is fixedly installed on the telescopic end of the limiting telescopic rod 15. A spring 16 is sleeved on the outer wall of the limiting telescopic rod 15.

[0032] An auxiliary blade 6 is fixedly installed at the center of the outer surface of each of the two longitudinal blades 5.

[0033] In one embodiment, the tool holder 3 includes a U-shaped frame 17 and a movable plate 18. The U-shaped frame 17 is fixedly installed on the top of the base 1, and the movable plate 18 is movably set at the front opening of the U-shaped frame 17, so as to facilitate flexible adjustment of the spatial layout of the tool holder 3.

[0034] In one preferred embodiment, a slide rail 12 is provided on the front side of the bottom of the base 1. A lead screw 14 is rotatably installed inside the slide rail 12. A servo motor 13 is fixedly installed on the front of the base 1. The drive end of the servo motor 13 passes through the base 1 and extends into the interior of the slide rail 12, where it is fixedly connected to the front end of the lead screw 14. An adjusting block 19 is sleeved on the outer wall of the lead screw 14 and is slidably installed on the slide rail 12. The top of the adjusting block 19 is fixedly connected to the bottom of the movable plate 18, which can precisely and flexibly adjust the position of the movable plate 18. This not only facilitates the cleaning of waste materials falling inside the U-shaped frame 17 and prevents waste material accumulation from affecting the normal operation of the tool holder 3, but also provides convenient conditions for the inspection and maintenance of corresponding mechanical parts inside the tool holder 3.

[0035] In one embodiment, two longitudinal blades 5 are fixedly installed on both sides of the top of the U-shaped frame 17 by bolts, one transverse blade 4 is fixedly installed on the rear side of the top of the U-shaped frame 17 by bolts, and another transverse blade 4 is fixedly installed on the top of the movable plate 18 by bolts. The blades are fixed to the U-shaped frame 17 and the movable plate 18 by bolts respectively, which facilitates the installation, disassembly and replacement of the blades, and is conducive to equipment maintenance and blade adjustment.

[0036] In one preferred embodiment, the adjusting block 19 has a threaded hole that matches the lead screw 14, and the adjusting block 19 is threadedly connected to the lead screw 14 through the threaded hole, which can convert the rotational motion of the lead screw 14 into the linear motion of the adjusting block 19, thereby realizing the flexible adjustment of the tool holder 3 structure.

[0037] In one embodiment, support frames 2 are fixedly installed on both sides of the bottom of the base 1, which can improve the stability of the equipment, reduce shaking, and ensure the smooth operation of the equipment.

[0038] In one preferred embodiment, symmetrically distributed stabilizing rods 10 are fixedly installed on the top of the upper mold 8, and the top of the stabilizing rods 10 passes through the fixing frame 9 and extends to the top of the fixing frame 9. The fixing frame 9 is provided with sliding holes corresponding to the position and number of the stabilizing rods 10, and the fixing frame 9 is slidably connected to the stabilizing rods 10 through the sliding holes, which can ensure the stability and verticality of the upper mold 8 when it moves up and down, making the stamping and trimming process more accurate and reliable.

[0039] In one embodiment, both the transverse blade 4 and the longitudinal blade 5 slide in contact with the outer surface of the lower mold 7, which can accurately cut the battery case residue and ensure trimming accuracy.

[0040] The working principle of this utility model is as follows: First, the stamped aluminum-plastic film battery case is placed on the lower mold 7. Then, the electric telescopic rod 11 is activated, and the drive end of the electric telescopic rod 11 drives the upper mold 8 to move vertically, causing the upper mold 8 to move downward and close at the top of the lower mold 7. The two combine to form a complete mold, thereby accurately positioning the battery case. As the upper mold 8 continues to move downward, it will drive the lower mold 7 to move synchronously. The movement of the lower mold 7 causes the limiting telescopic rod 15 to retract, while simultaneously compressing the spring 16. When the lower mold 7 and the upper mold 8 move downward, they enter the cutter holder 3. At this time, the horizontal blade 4 and the vertical blade 5 will directly cut off the part of the battery case that extends beyond the mold, completing the trimming operation. Afterward, the upper mold 8 is controlled to return to its original position, and the lower mold 7 returns to its original position under the elastic restoring force of the spring 16. After the upper mold 8 and the lower mold 7 separate, the trimmed aluminum-plastic film battery case can be removed from the lower mold 7.

[0041] This equipment employs a four-sided synchronous cutting trimming process. When residual material remains on all four edges of the aluminum-plastic film battery casing, the resulting waste forms a U-shaped structure. Given the integrated and continuous spatial structure of this U-shaped waste, it is inconvenient to clean. While the equipment uses the horizontal blade 4 and vertical blade 5 to trim the battery casing, an auxiliary blade 6 simultaneously performs a cutting and separating action on the already cut waste. The auxiliary blade 6 precisely targets specific parts of the waste, dividing the originally integral U-shaped waste into two relatively independent parts. The separated waste no longer connects to form complex structures but falls directly to the top of the base 1. Because the waste has been divided into two parts, it is easier to grasp, transport, and collect during the cleaning process, significantly improving the convenience of subsequent waste cleaning and increasing the overall efficiency of the production process.

[0042] During the use of the tool holder 3, when the equipment is not in operation, the servo motor 13 can be started. The drive end of the servo motor 13 drives the lead screw 14 to rotate. Utilizing the threaded transmission principle between the lead screw 14 and the adjusting block 19, as well as the sliding fit between the adjusting block 19 and the slide rail 12, the adjusting block 19 is made to move stably longitudinally along the slide rail 12. The movement of the adjusting block 19 causes the movable plate 18 to move synchronously, thereby separating the integrated tool holder 3, which was originally composed of the U-shaped frame 17 and the movable plate 18, into two parts. As the movable plate 18 moves forward, the front end of the U-shaped frame 17 is fully open. This not only facilitates the cleaning of scrap materials that have fallen inside the U-shaped frame 17, preventing scrap material accumulation from affecting the normal operation of the tool holder 3, but also provides convenient conditions for the inspection and maintenance of the corresponding mechanical parts inside the tool holder 3. It enables the timely detection and elimination of potential faults, thereby effectively improving the stability and reliability of the equipment operation.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
