Description

Technical Field

[0001] This utility model relates to a battery disassembly device, and more particularly to a positioning device for cutting individual batteries. Background Technology

[0002] Refined dismantling of individual battery cells is a key technology for achieving efficient recycling and resource reuse of waste batteries. Its core objective is to safely and environmentally extract valuable materials from batteries, such as positive and negative electrode materials, electrolytes, and separators. During the dismantling process, pretreatment is required to ensure the safety and operability of the dismantling. Then, the outer casing is cut by mechanical cutting to separate the outer casing from the core. The positive and negative electrode plates and separators in the core are then efficiently separated. The separated electrode plates are then further separated into active materials and current collectors for further recycling and purification. During the cutting of individual battery cells, the battery needs to be positioned to ensure that the internal core pack is not damaged while cutting the battery casing.

[0003] In the process of cutting the battery casing, existing technology typically involves positioning the battery on the side or top to ensure cutting accuracy and prevent displacement during cutting. However, this positioning usually only targets the end closest to the cutting point, which can cause the rear end of the battery to tilt or swing during cutting, affecting cutting accuracy and potentially damaging the battery core.

[0004] Therefore, this invention aims to provide a positioning device for cutting single-cell batteries, which can position multiple locations of the battery to improve the stability of the battery during cutting and thus improve the cutting accuracy of the battery casing. Utility Model Content

[0005] This invention provides a positioning device for cutting single-cell batteries, which can effectively solve the above-mentioned problems.

[0006] This utility model is implemented as follows:

[0007] A positioning device for cutting single-cell batteries, comprising:

[0008] Transfer machine;

[0009] A first positioning structure fixed on a transfer machine platform, the first positioning structure including a first positioning member for positioning the battery, and a first cutting member movably mounted on the side of the first positioning member away from the battery;

[0010] A second positioning structure is provided opposite to the first positioning structure. The second positioning structure includes a lateral positioning adjustment member provided on the transfer machine platform and a second positioning member slidably installed in the lateral positioning adjustment member. When the first positioning member is engaged with the battery, the lateral positioning adjustment member drives the second positioning member to move and the second positioning member presses against the battery.

[0011] As a further improvement, a rib groove is provided on the transfer machine platform, and an initial positioning member is provided on the side of the second positioning structure near the battery, which is slidably connected in the rib groove. When the battery moves to the front end of the first positioning structure, the initial positioning member pushes the battery into the first positioning structure.

[0012] As a further improvement, the first positioning component includes a positioning gantry mounted on the table of the transfer machine. The positioning gantry is respectively equipped with a first pressure plate drive and a first cutting push rod. The lower end of the first pressure plate drive is connected to a housing clamping frame, and the output end of the first cutting push rod is connected to a cutting blade.

[0013] As a further improvement, the housing clamping frame includes a clamping frame slider connected to the first pressure plate drive member. The clamping frame slider is locked to a pressure plate, and a reinforcing plate is locked above the pressure plate. The reinforcing plate is slidably engaged with the positioning frame guide rail inside the positioning gantry through the clamping plate slider.

[0014] As a further improvement, a housing receiving groove is provided at the lower end of the positioning gantry, and an auxiliary housing positioning member is provided on the side of the housing receiving groove away from the battery. When the auxiliary housing positioning member is pushed out, the initial positioning member pushes the battery to fit against the auxiliary housing positioning member.

[0015] As a further improvement, the lateral positioning adjustment member is provided with a second positioning frame moving guide rail. The second positioning member includes a second positioning slider that is movably engaged with the second positioning frame moving guide rail. The second positioning slider is locked onto a second positioning plate. The second positioning plate is connected to the lateral positioning screw of the lateral positioning adjustment member through a nut.

[0016] As a further improvement, the second positioning member also includes a second positioning guide rail locked onto the second positioning plate, a second positioning push rod locked to the top of the second positioning plate, and a counter-side clamping bracket slidably fitted onto the second positioning guide rail at the bottom of the second positioning push rod, the counter-side clamping bracket pressing against the rear end of the top surface of the battery.

[0017] As a further improvement, the opposite-side clamping frame includes an opposite-side mating plate that mates with the second positioning guide rail. A reversing block is locked onto the opposite-side mating plate, and an opposite-side clamping plate is locked onto the reversing block. The opposite-side clamping plate is pressed against the rear end of the battery.

[0018] The beneficial effects of this utility model are:

[0019] In existing battery cutting devices, positioning structures are typically set around the cutting structure, which can easily cause the rear end of the battery to tilt upwards or swing during the cutting process. Therefore, this invention first uses a first positioning structure to fix the front end of the battery at the cutting point, and then sets a second positioning structure in the opposite direction of the first positioning structure to fix the rear end of the battery as well. This achieves fixation at both the front and rear points of the battery, thus achieving a stable positioning effect during the cutting process of the first cutting piece. At the same time, the adjustment of the lateral positioning adjustment component allows the second positioning structure to adapt to the size of the battery. Even when cutting small batteries, the second positioning structure can be moved to the corresponding position by the lateral positioning adjustment component. This provides strong adaptability and enables precise, multi-point positioning of the battery. Attached Figure Description

Detailed Implementation

[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Reference Figures 1-6As shown, a positioning device for cutting single-cell batteries includes: a transfer table 20; a first positioning structure 31 fixed on the transfer table 20, the first positioning structure 31 including a first positioning member 311 for positioning the battery, a first cutting member 312 movably mounted on the side of the first positioning member 311 away from the battery; and a second positioning structure 32 opposite to the first positioning structure 31, the second positioning structure 32 including a lateral positioning adjustment member 321 disposed on the transfer table 20, and a second positioning member 322 slidably mounted within the lateral positioning adjustment member 321, wherein when the first positioning member 311 engages with the battery, the lateral positioning adjustment member 321 drives the second positioning member 322 to move and the second positioning member 322 presses against the battery.

[0032] In existing battery cutting devices, positioning structures are typically set around the cutting structure, which can easily cause the rear end of the battery to tilt upwards or swing during the cutting process. Therefore, this invention first uses a first positioning structure 31 to position and fix the front end of the battery at the cutting point. In addition, a second positioning structure 32 is set in the opposite direction of the first positioning structure 31 to position and fix the rear end of the battery as well. This achieves fixation at both the front and rear points of the battery, thereby achieving a stable positioning effect during the cutting process of the first cutting piece 312. At the same time, the adjustment of the lateral positioning adjustment piece 321 can also make the second positioning structure 32 adaptable to the size of the battery. Even when cutting small batteries, the second positioning structure 32 can be moved to the corresponding position by the lateral positioning adjustment piece 321. This provides strong adaptability and enables precise, multi-point positioning of the battery.

[0033] After the battery is transferred, due to the different specifications of the batteries, it may not be able to accurately reach the position of the cutting structure. Therefore, the transfer table 20 of this utility model has a rib groove. The second positioning structure 32 is provided with an initial positioning member 33 that is slidably connected in the rib groove on the side near the battery. When the battery moves to the front end of the first positioning structure 31, the initial positioning member 33 pushes the battery into the first positioning structure 31. The initial positioning member 33 is an embedded push rod structure, so that the battery can be pushed to the position of the first cutting member 312 and the first positioning member 311 through the initial positioning member 33 to form the initial positioning.

[0034] After the battery is pushed to its initial position, it is first positioned by the first positioning component 311. Specifically, the first positioning component 311 includes a positioning gantry 3111 set on the table of the transfer machine 20. The positioning gantry 3111 is respectively equipped with a first pressure plate drive component 3112 and a first cutting push rod 3113. The lower end of the first pressure plate drive component 3112 is connected to a housing clamping frame 3114, and the output end of the first cutting push rod 3113 is connected to a cutting blade 3115. The first pressure plate drive component 3112 and the first cutting push rod 3113 can drive the housing clamping frame 3114 and the cutting blade 3115 to move respectively, so that the housing clamping frame 3114 presses down first and then the cutting blade 3115 moves down.

[0035] Specifically, the housing clamping frame 3114 includes a clamping frame slider 31141 connected to the first pressure plate drive member 3112. The clamping frame slider 31141 is locked onto a pressure plate 31142. A reinforcing plate 31143 is locked above the pressure plate 31142. The reinforcing plate 31143 slides with the positioning frame guide rail 31111 inside the positioning gantry 3111 through the clamping plate slider 31144. When positioning the front end of the battery, the first pressure plate drive member 3112 drives the reinforcing plate 31143 to press down along the positioning frame guide rail 31111, so that the clamping plate 31142 presses the battery.

[0036] The cut battery casing needs to be processed. If it is left directly on the transfer machine 20, it will cause accumulation. Therefore, the lower end of the positioning gantry 3111 in this embodiment is provided with a casing receiving groove 34. An auxiliary casing positioning member 35 is provided on the side of the casing receiving groove 34 away from the battery. When the auxiliary casing positioning member 35 is pushed out, the initial positioning member 33 pushes the battery to fit against the auxiliary casing positioning member 35. The initial positioning member 33 and the auxiliary casing positioning member 35 can form a counter-coupling. Combined with the first positioning structure 31 and the second positioning structure 32, the battery will be positioned at four points before cutting. After the battery casing is cut, not only will the cut-off casing part fall into the casing receiving groove 34, but part of the electrolyte in the casing will also flow into the casing receiving groove 34 along the cut. Furthermore, due to the pressure generated by the second positioning structure 32 at the rear end, the electrolyte at the rear end will also be pushed forward, causing it to flow out along the direction of the cut, so as to discharge the electrolyte in the battery as much as possible and reduce the difficulty of the rear processing.

[0037] The position of the second positioning component 322 is not fixed and needs to be changed according to the battery size. Specifically, the lateral positioning adjustment component 321 is provided with a second positioning frame moving guide rail 3211. The second positioning component 322 includes a second positioning slider 3221 that is movably engaged with the second positioning frame moving guide rail 3211. The second positioning slider 3221 is locked onto a second positioning plate 3222. The second positioning plate 3222 is connected to the lateral positioning screw of the lateral positioning adjustment component 321 through a nut, so that the distance between the second positioning plate 3222 and the first positioning structure 31 can be adjusted according to the battery size.

[0038] The second positioning plate 3222 itself can move along the Z-axis. Specifically, the second positioning plate 322 also includes a second positioning guide rail 3223 locked onto the second positioning plate 3222. A second positioning push rod 3224 is locked to the top of the second positioning plate 3222. A counter-side clamping bracket 3225 is connected to the bottom of the second positioning push rod 3224 and slides onto the second positioning guide rail 3223. The counter-side clamping bracket 3225 is pressed against the rear end of the top surface of the battery, thereby preventing the rear end of the battery from tilting up and laying a good foundation for the next stage of cutting or positioning.

[0039] To prevent the battery from being flattened during battery positioning, the opposite clamping frame 3225 includes an opposite mating plate 32251 that cooperates with the second positioning guide rail 3223. A reversing block 32252 is locked on the opposite mating plate 32251, and an opposite clamping plate 32253 is locked on the reversing block 32252. The opposite clamping plate 32253 is pressed against the rear end of the battery, thereby making the opposite clamping plate 32253 and the second positioning push rod 3224 misaligned and not on the same straight line, thus achieving misaligned pressure.

[0040] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
