Description

Technical Field

[0001] This utility model relates to the field of battery processing equipment technology, and in particular to an integrated machine for bending, heat-pressing and shaping lithium-ion batteries. Background Technology

[0002] With the continuous emergence of new consumer electronics products such as smartwatches, smart bracelets, earphones, and smart rings, irregularly shaped batteries, due to their shape better fitting the battery compartments of these devices, possess excellent spatial adaptability. Compared to traditional batteries, they can be smaller and thinner, while also exhibiting a certain degree of curvature. Curved batteries have revolutionized the existing battery design concept, achieving battery flexibility while maintaining electrical performance, thus adapting to the close-fitting shapes required in wearable electronic devices.

[0003] Compared to traditional square lithium batteries with flat bodies and straight edges, the folding axis of curved batteries is not a straight line but an arc. During folding, the battery body is subjected to uneven stress, causing the electrode sheets to warp. This easily leads to battery deformation and damage, further degrading battery cycle performance, electrical performance, and safety performance. Therefore, traditional folding and shaping equipment is only suitable for square / cylindrical batteries and cannot meet the folding requirements of curved, wavy, and other irregularly shaped batteries.

[0004] Existing curved structures specifically designed for curved batteries (such as the edge curvature of pouch batteries) require multiple independent machines to complete folding, hot pressing, and shaping operations in steps. This results in low efficiency and poor appearance. Furthermore, the folding, hot pressing, and shaping of both sides are carried out in steps, which disperses the process. Repeated handling can easily lead to electrode misalignment, resulting in repeated positioning errors and secondary damage. Utility Model Content

The first driving member can be a combination of a motor and a lead screw, or it can be a linear motor or a cylinder. This embodiment uses a cylinder as an example for explanation, that is, a first cylinder 140 is mounted at the end of the first guide rail 110 near the electrical box 500, and the first cylinder 140 serves as the first driving member. The telescopic rod of the first cylinder 140 is connected to the first mounting base 120. When the telescopic rod of the first cylinder 140 moves in a telescopic motion, it will cause the first mounting base 120 to slide on the first guide rail 110.

[0039] In the embodiments of this application, the battery cell clamp includes a movable pressure plate 131, a second driving member, and a battery mounting member 132. The battery mounting member 132 is used to fix the battery cell to be processed. It can be used by vacuum adsorption with a suction cup to adsorb and fix the battery cell to be processed onto the battery mounting member 132, and then the movable pressure plate 131 is used to press and clamp it for subsequent edge folding and heat-forming processing. Specifically, the movable pressure plate 131 is movably installed on one side of the battery mounting member 132, that is, the movable pressure plate 131 can move towards the battery mounting member 132 to clamp the battery cell on the battery mounting member 132; it can also move away from the battery mounting member 132 to remove the edge-folded and heat-formed battery cell. The battery mounting component 132 has a mounting plate 1321 adapted to the shape of the battery. The movable pressure plate 131 has a clamping notch 1311 adapted to the shape of the battery on the side facing the battery mounting component. The mounting plate 1321 and the clamping notch 1311 are positioned correspondingly. The second driving member is connected to the movable pressure plate 131 to drive the movable pressure plate 131 to move. The shapes of the mounting plate 1321, the clamping notch 1311, the positioning surface 2231, and the positioning groove 350 are almost identical, all designed to adapt to the battery cell to be processed. For example, to adapt to an arc-shaped battery, the mounting plate 1321, the clamping notch 1311, the positioning surface 2231, and the positioning groove 350 are all arc-shaped.

[0040] In the embodiments of this application, a first mounting plate 121 is fixed to one end of the first mounting base 120. The first mounting plate 121 has a sliding groove 1211. One end of the movable pressure plate 131 passes through the sliding groove 1211 and is connected to the second driving member.

The telescopic rod of the second cylinder 133 is connected to the fixed block 134. When the telescopic rod of the second cylinder 133 moves, it will drive the movable pressure plate 131 to move, so as to increase the distance between the movable pressure plate 131 and the battery mounting component 132, making it easier to remove the processed battery cell, or to decrease the distance between the movable pressure plate 131 and the battery mounting component 132, so as to press the battery cell to be processed adsorbed on the battery mounting component 132.

[0041] like Figure 6As shown in the embodiment of this application, the second guide rail 210 is fixedly installed on the top of the first mounting bracket 420.

The positioning surface 2231 is provided on one side of the positioning block 223. The third driving member can be a combination of a motor and a lead screw, or a linear motor or a cylinder. This embodiment uses a cylinder as an example. A side plate 421 is fixedly installed on one side of the first mounting bracket 420. A third cylinder 221 is installed on the outside of the side plate 421. The third cylinder 221 serves as the third driving member, and the telescopic rod of the third cylinder 221 passes through the side plate 421 and is connected to a connecting block 230 on the other side of the side plate 421. One end of the second mounting base 222 is connected to the telescopic rod of the third cylinder 221. Specifically, the second mounting base 222 has a connecting groove 2221 at one end. The diameter of the end of the connecting block 230 away from the third cylinder 221 is larger than the diameter of the end of the connecting groove 2221 near the third cylinder 221. The connecting block 230 is inserted into the connecting groove 2221 to connect one end of the second mounting base 222 with the telescopic rod of the third cylinder 221. Simultaneously, the telescopic movement of the telescopic rod of the third cylinder 221 will cause the second mounting base 222 to move on the second guide rail 210. A slider is also provided at the bottom of the second mounting base 222, with one end sliding on the second guide rail 210 to allow the second mounting base 222 to slide on the second guide rail 210. Furthermore, the second mounting base 222 with two positioning components slides on the two second guide rails 210 respectively to achieve positioning on both sides of the battery cell clamp.

[0042] like Figure 7As shown in the embodiment of this application, the third guide rail 310 is fixedly installed on the top of the second mounting bracket 430. The hot-heating component includes a fourth driving member, a third mounting base 322, and a hot-heating assembly. The hot-heating assembly is installed on the third mounting base 322, and the third mounting base 322 is slidably installed on the third guide rail 310. The fourth driving member is connected to the third mounting base 322 and is used to drive the third mounting base 322 to slide on the third guide rail 310. The fourth driving component can be a combination of a motor and a lead screw, or a linear motor or a cylinder. This embodiment uses a combination of a motor and a lead screw as an example. Specifically, the fourth driving component includes a motor 321 and a ball screw. The ball screw is rotatably mounted inside the third guide rail 310. One end of the ball screw is connected to the motor 321 for transmission, and the nut of the ball screw is connected to the third mounting base 322. More specifically, a driven wheel can be fixedly mounted at one end of the ball screw, and a driving wheel can be mounted on the output shaft of the motor 321. The driven wheel meshes with the driving wheel to realize that the motor 321 rotates to drive the ball screw to rotate, thereby driving the third mounting base 322 to move on the third guide rail 310. Alternatively, a driven wheel can be fixedly mounted at one end of the ball screw, and a driving wheel can be mounted on the output shaft of the motor 321. A transmission chain is wound around the driving wheel and the driven wheel to realize that the motor 321 rotates to drive the ball screw to rotate.

A heating module is provided inside the hot stamping shaping block 3232. The heating module can be heating tubes evenly arranged inside the hot stamping shaping block 3232. A positioning groove 350 is located at the end of the hot stamping shaping block 3232 away from the positioning assembly, and the shape of the positioning groove 350 is the same as that of the clamping notch 1311. A slider is also provided at the bottom of the third mounting base 322. One end of the slider is slidably mounted on the third guide rail 310 so that the third mounting base 322 can be slidably mounted on the third guide rail 310. The third mounting of the two hot heat assembly slides on the two third guide rails 310 respectively to achieve the edge folding and hot heat shaping of the battery cell to be processed.

[0044] The lithium-ion battery folding and shaping integrated machine of this application achieves efficient and precise folding of curved lithium batteries through a process of manual feeding → product positioning → mechanical folding → hot stamping → shaping and setting → manual unloading, ensuring product consistency and yield. Specifically, it includes the following operation steps:

[0045] (1) Simultaneously activate two third cylinders 221, that is, extend the telescopic rods of the two third cylinders 221 at the same time, and bring the two positioning blocks 223 close to the edge of the cell clamp to form a cell placement cavity and achieve precise positioning;

[0046] (2) The battery cell is placed manually on the arc plate of the battery mounting part 132 and fixed by adsorption. The aluminum-plastic film on the edge of the battery cell is adsorbed and fixed to prevent the battery cell from falling out of the fixture. The vacuum adsorption force is used to precisely adjust the battery cell to the theoretical position and pre-fix it to prevent it from shifting or falling in the subsequent process, and at the same time prepare for mechanical clamping.

[0047] (3) Start the second cylinder 133, that is, the telescopic rod of the second cylinder 133 retracts and drives the movable pressure plate 131 to move closer to the battery mounting part 132, so as to press the adsorbed battery cell, thereby clamping the battery cell through the relative cooperation of the movable pressure plate 131 and the battery mounting part 132.

[0048] (4) Simultaneously start the two third cylinders 221 and retract the telescopic rods of the two third cylinders 221 to their original positions, leaving enough space for the movement of the battery cell clamp.

[0049] (5) Start the first cylinder 140, that is, the telescopic rod of the first cylinder 140 retracts, driving the first mounting base 120 to move towards the electrical box 500, thereby realizing the clamping component to move towards the electrical box 500, and moving until the battery cell to be processed is aligned with the positioning groove.

[0050] (6) Simultaneously start two motors 321 to drive the two hot ironing components to move relative to each other, so that the two hot ironing components move close to the edge of the battery cell clamp according to the set stroke, and move to the preheating and ironing edge position to turn off the motor 321 to complete the preheating and ironing edge processing.

[0051] (7) Restart the first cylinder 140, that is, the telescopic rod of the first cylinder 140 extends a certain distance, driving the battery cell clamp to move away from the electrical box 500. When it moves to the set stroke (preheating and folding), the edge of the battery cell that needs to be folded is exactly located on the side of the hot heat forming block 3232, and maintains a precise and small distance from the working surface of the hot heat forming block 3232. That is, the folding plane of the battery cell and the parallel trajectory of the hot heat forming block 3232 need to be parallel, and the correct initial gap needs to be reserved between them.

[0052] (8) Simultaneously start the two motors 321 to drive the two hot stamping components to move relative to each other again, moving to the preset stroke (hot pressing and shaping). In this step, the target position of the hot stamping components is a more precise endpoint based on the "preheating and hot stamping edge position" in step (7). This position can be defined as the position where the heating working surface of the hot stamping and shaping block 3232 is in complete contact with the battery edge area and a preset process pressure (F) is applied. This is the small displacement from the moment it contacts the workpiece surface until the preset pressure is reached and the final shape is pressed. This stroke is the key to quality and requires precise control of speed and pressure. The working surface of the hot stamping and shaping block 3232 and the battery edge area need to be in uniform and parallel contact.

[0053] (9) Simultaneously start the two motors 321 to rotate in opposite directions, driving the two heating components to move in the opposite direction (reset), so as to leave space for the battery cell clamp to move easily;

[0054] (10) Restart the first cylinder 140, that is, the telescopic rod of the first cylinder 140 continues to extend a certain distance (reset), driving the battery cell clamp to move between the two positioning components;

[0055] (11) Start the second cylinder 133 again, that is, the extension rod of the second cylinder 133 extends, the battery cell clamp opens, and the processed battery cell is manually removed, thus completing the edge folding and hot heat shaping of the battery cell.

[0056] In the lithium-ion battery folding and shaping integrated machine of this application, the first guide rail 110, the second guide rail 210 and the third guide rail 310 are all precision guide rails, and the motor 321 is a servo motor 321. This lithium-ion battery folding and shaping integrated machine integrates the folding mechanism, the heat-pressing module and the arc-shaped shaping mold in the same station, and achieves synchronous action through multi-axis linkage. In the cell positioning operation, a cylinder and precision guide rail mechanical positioning mechanism are used to ensure accurate manual placement of the cell. In the edge folding operation, a servo motor 321 and a high-precision module are used to fold the edge of the cell in an arc shape to meet the product's arc requirements. The servo motor 321 controls the folding force to prevent deformation or damage to the cell electrode sheets. In the hot stamping operation, a temperature control system is used, with heating tubes and temperature sensing wires maintaining the set temperature. The hot stamping shaping block 3232 pre-folds the aluminum-plastic film, subjecting the edge of the cell's aluminum-plastic film to heat pressure. In the shaping and setting operation, the cell enters the hot stamping shaping blocks 3232 on both sides for hot pressing and setting. The servo motor and high-precision module heat press and set the edge of the cell to prevent springback deformation.
