Description

Technical Field

[0001] The utility model relates to the technical field of batteries, in particular to a coiled material guiding device. Background Art

[0002] Battery electrodes need to go through different processes such as die-cutting, slitting and winding before they can be made into battery cells. In each process, the front and rear electrode rolls are connected by a splicing device.

[0003] Currently, the splicing device is located downstream of the unwinding mechanism and maintains a certain distance from it. During the unwinding operation, the unwinding mechanism not only provides the unwinding function but also provides a certain amount of tension for the coil to maintain stable tape travel. Therefore, when the tail of the coil is about to leave the unwinding mechanism, the unwinding mechanism stops and the old coil and the new coil are spliced ​​in the splicing device. This causes the tail of the old coil between the unwinding mechanism and the splicing mechanism to be scrapped, resulting in material waste. Utility Model Content

[0029] like Figure 1 As shown, the embodiment of the present invention provides a coiled material guiding device, which includes an unwinding mechanism 100, a tape splicing mechanism, and a tail material guiding assembly.

[0030] like Figure 1 and Figure 2 As shown, specifically, along the running direction, the splicing mechanism is positioned downstream of the unwinding mechanism 100. The tail material guide assembly is positioned between the unwinding mechanism 100 and the splicing mechanism along the running direction. The tail material guide assembly includes a tail material pinch roller assembly 300, a tail material deflection correction assembly 400, and a tail material detector 500. Along the running direction, the tail material deflection correction assembly 400 is positioned upstream of the tail material pinch roller assembly 300. The tail material detector 500 is used to detect the position of the material strip.

[0031] The coil guiding device provided in this embodiment has a tail material guiding assembly disposed between the unwinding mechanism 100 and the splicing mechanism. The tail material pressing roller assembly 300 can press the tail material, maintaining a certain tension in the tail material and ensuring a smooth operation of the tail material. The tail material deviation correction assembly 400 can correct the deviation of the tail material, ensuring that the tail material runs along an accurate trajectory. The tail material detection component 500 can detect the position of the tail material and provide position information for the operation of the tail material deviation correction assembly 400 and the tail material pressing roller assembly 300. By disposing the tail material guiding assembly between the unwinding mechanism 100 and the splicing mechanism, the coil guiding device can fully utilize the tail material that would otherwise be discarded, significantly improving the utilization rate of the coil material and greatly reducing the waste of tail material between the unwinding mechanism 100 and the splicing mechanism. This not only reduces the consumption of raw materials, but also directly reduces production costs, bringing significant economic benefits to the enterprise.

[0032] like Figure 1 As shown, in this embodiment, the coil guide device also includes a tension sensor 901 and a tension swing rod 902, and the tension sensor 901 and the tension swing rod 902 are both arranged on the downstream side of the tape splicing mechanism. The tension sensor 901 can detect whether the tension of the material strip is in compliance with regulations, and the tension swing rod 902 is used to adjust the tension of the material strip to maintain the quality of tape travel. In this embodiment, a tail material guide assembly is arranged between the unwinding mechanism 100 and the tape splicing mechanism, and the tail material clamping roller group 300 clamps the tail material, providing tension to the tail material that has separated from the unwinding mechanism, thereby ensuring the normal operation of the tension sensor 901 and the tension swing rod 902, solving the problem of no tension after the material strip separates from the unwinding mechanism during operation, allowing the equipment to continue to operate normally, and realizing further consumption and utilization of the tail material.

[0033] Optionally, the web guiding device further includes a main controller, with which both the tail material detector 500 and the tail material deviation correction assembly 400 communicate. The tail material detector 500 can detect the position of the web in real time and promptly provide feedback to the main controller. If the tail material deviates from its position, the main controller can quickly respond by adjusting the operation of the tail material deviation correction assembly 400 to promptly correct the position of the tail material. For example, the main controller can be a PLC controller, and the tail material detector 500 can be an infrared sensor.

[0034] like Figure 1 As shown, the coil guide device optionally further includes a coil diameter detector 800 for detecting the coil diameter of the unwinding mechanism 100. This real-time and accurate detection of the coil diameter of the unwinding mechanism 100 by the coil diameter detector 800 provides an important basis for controlling the operation of the coil guide device. Exemplarily, the coil diameter detector 800 is an ultrasonic sensor located to the side of the unwinding shaft of the unwinding mechanism 100. Specifically, the coil diameter detector 800 communicates with a main controller, which can dynamically adjust the unwinding speed, tension, and operating parameters of the tail guide assembly based on changes in the coil diameter.

[0035] In this embodiment, when the tail material pressure roller assembly 300 is activated to suppress the tail material, the unwinding mechanism 100 slows down to a speed of less than 20 m / min. When the tail material detector 500 detects that the end of the tail material has passed through and separated from the tail material deflection correction assembly 400, the unwinding mechanism 100 stops, thereby only discarding the tail material between the tail material deflection correction assembly 400 and the splicing platform 200. It will be appreciated that the tail material pressure roller assembly 300 is positioned adjacent to the splicing mechanism to minimize waste of tail material.

[0036] like Figure 2 As shown, the tailings pinch roller assembly 300 optionally includes a first roller 310 and a second roller 320 that are parallel to each other, and the tailings guiding assembly further includes a pinch driver 600 connected to the first roller 310. The pinch driver 600 is capable of driving the first roller 310 toward or away from the second roller 320. In other words, the first roller 310 and the second roller 320 in the tailings pinch roller assembly 300 cooperate with each other, and under the action of the pinch driver 600, the tailings can be stably pressed. This pinching action effectively prevents the tailings from becoming loose, deflected, or curled due to tension changes or external interference during the guiding process, ensuring that the tailings are always smoothly transported along the predetermined path, thereby improving the reliability and stability of the tailings guiding process.

[0037] like Figure 2As shown, optionally, the tail material guiding assembly further includes a rotary drive member 700, which is connected to the second roller 320 and is used to drive the second roller 320 to rotate. Utilizing the rotary drive member 700 to drive the second roller 320 to rotate provides active power support for the conveying of the tail material. This helps the tail material overcome friction and resistance during the guiding process, allowing for smoother conveying, reducing problems such as stretching, deformation, or accumulation of the tail material caused by poor conveying, and improving the efficiency and quality of the tail material conveying. In the present embodiment, the rotary drive member 700 is a servo motor that drives the second roller 320 to actively rotate, while the first roller 310 passively rotates with the second roller 320.

[0038] like Figure 2 As shown, the compacting drive 600 optionally includes a telescopic cylinder, which is disposed on the side of the first roller 310 facing away from the second roller 320. The telescopic cylinder is extended and retracted in the direction from the first roller 310 to the second roller 320. The reciprocating motion of the telescopic cylinder allows the first roller 310 and the second roller 320 to compact or loosen the tail material. The telescopic cylinder moves smoothly and accurately.

[0039] like Figure 1 As shown, the splicing mechanism optionally includes a splicing platform 200, the upper surface of which is flush with the upper surface of the second roller 320. This arrangement allows the tailings to remain horizontal and stable as they transition from the tailing guide assembly to the splicing mechanism, achieving a smooth transition. This smooth transition reduces the difficulty and complexity of splicing, improves the efficiency and quality of splicing, and reduces the likelihood of splicing failures or poor splicing quality due to an uneven transition.

[0040] like Figure 2 As shown, optionally, the tail material deviation correction component 400 includes a movable base 410 and a tail material deviation correction roller group 420. The tail material deviation correction roller group 420 is arranged on the movable base 410, and the movable base 410 can drive the tail material deviation correction component 400 to move. In a specific implementation, when the tail material deviates slightly during the transmission process, the tail material deviation correction roller group 420 carries the tail material, and the movable base 410 structure moves as a whole and drives the tail material deviation correction roller group 420 to adjust the position, so that the tail material returns to the correct transmission path, achieving deviation correction. In this embodiment, the movable base 410 can be a three-axis moving mechanism that can move in all three directions to achieve deviation correction.

[0041] like Figure 2As shown, optionally, the tail material deviation correction roller group 420 includes a first movable roller 421 and a second movable roller 422 that are parallel to each other. The first movable roller 421 and the second movable roller 422 are arranged on the movable base 410 so as to be relatively movable. The first movable roller 421 and the second movable roller 422 can move toward each other or move away from each other. The first movable roller 421 and the second movable roller 422 move toward each other to clamp the tail material, making it easier for the movable base 410 to move and correct the deviation. When the first movable roller 421 and the second movable roller 422 move away from each other, the tail material can be released and a gap can be maintained with the tail material. In this embodiment, the first movable roller 421 and the second movable roller 422 are respectively driven by cylinders, thereby being movable relative to the movable base 410.

[0042] Optionally, the web guiding device further comprises a deflection correction drive member, and the movable base 410 is connected to the deflection correction drive member. In other words, the deflection correction drive member drives the movable base 410 to move, providing a driving force for deflection correction. In this embodiment, the deflection correction drive member can be a deflection correction motor.

[0043] Optionally, the deflection correction drive is also connected to the unwinding mechanism 100. The deflection correction drive is connected to the unwinding mechanism 100, and through the action of the deflection correction drive, the unwinding mechanism 100 and the tail material deflection correction assembly 400 are synchronized to correct the deflection, thereby realizing coordinated control of the entire device during operation.

[0044] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
