Description

Technical Field

[0001] This utility model relates to the technical field of lithium battery processing, and in particular to an adjustable laser cutting embossing device. Background Technology

[0002] In the manufacturing process of lithium-ion batteries and related products, the tab embossing process is a key step in the laser cutting process; however, this process is often overlooked in actual production.

[0003] In actual production, the presence or absence of tab embossing has a crucial impact on the quality of subsequent laser cutting processes. If the tabs are not properly embossed, a series of defects are likely to occur during laser cutting, such as tab folding during winding and sticking during cutting. In-depth analysis revealed that the main root cause of these defects is insufficient tab strength. When the tab strength is insufficient, it will sag due to gravity during the rolling process, failing to perfectly conform to the predetermined process requirements, thus leading to the aforementioned quality problems and severely impacting production efficiency and finished product quality.

[0004] To address the issue of insufficient tab strength, traditional laser cutting machines employ a method of processing the tab using pressure rollers with fixed patterns on both the A and B sides. Common pressure roller patterns include vertical stripes and dot matrix patterns. These rollers apply pressure with specific patterns to the tab surface, enhancing its strength to some extent and reducing tab sagging. However, this traditional pressure roller method has significant limitations. Due to its single and fixed embossing pattern, it sometimes fails to effectively address abnormal problems that arise during tab processing in complex and ever-changing production conditions, making it difficult to meet increasingly stringent production process and product quality requirements. Utility Model Content

[0005] In view of the aforementioned problems with existing embossing rollers, the aim is to provide an adjustable laser cutting embossing device.

[0006] The specific technical solution is as follows:

[0007] An adjustable laser cutting embossing device includes: a main shaft and a plurality of embossing wheels with different embossing patterns on the outside, each of the embossing wheels being coaxially and rotatably mounted on the outside of the main shaft.

[0008] As a further improvement and optimization of this solution, each of the embossing wheels is mounted on the main shaft in a unidirectional rotational manner via a one-way self-locking mechanism.

[0009] As a further improvement and optimization of this solution, the one-way self-locking mechanism is a ratchet mechanism.

[0010] As a further improvement and optimization of this solution, the ratchet mechanism is an internal ratchet mechanism and is located between the inner wall of the embossing wheel and the outer wall of the main shaft.

[0011] As a further improvement and optimization of this solution, the internal ratchet mechanism includes:

[0012] A ratchet, which is coaxially disposed on the inner wall of the embossing wheel, and the inner wall of the ratchet is provided with ratchet teeth;

[0013] At least two pawls, one end of each pawl being rotatably connected to the main shaft and the other end engaging with the ratchet teeth in a one-way self-locking engagement.

[0014] As a further improvement and optimization of this solution, the two pawls are respectively located on both sides of the main shaft along the radial direction of the main shaft.

[0015] As a further improvement and optimization of this solution, the ratchet and the embossing wheel are integrated into one structure.

[0016] As a further improvement and optimization of this solution, the ratchet and the ratchet wheel are integrated into one structure.

[0017] As a further improvement and optimization of this solution, the two adjacent embossing wheels are arranged to contact each other.

[0018] As a further improvement and optimization of this solution, the plurality of embossing wheels are distributed at equal intervals along the axial direction of the main shaft.

[0019] The positive effects of the above technical solution compared with the existing technology are:

[0020] (1) By setting multiple embossing wheels with different embossing patterns on the outside, and each embossing wheel can be unidirectionally rotated and installed on the main shaft, different embossing wheels can be flexibly selected for embossing operations according to actual production needs, so as to realize a combination of various embossing shapes and methods, meet different process requirements, and improve the applicability and flexibility of the device.

[0021] (2) The one-way self-locking mechanism of this utility model ensures that the embossing wheel can only rotate in one direction, and can stably maintain the set position and state during the embossing process, avoiding the instability of the embossing effect due to reverse rotation or accidental movement, and ensuring the uniformity and consistency of the embossing quality.

[0028] Figure 1 This is a schematic diagram of the structure of an adjustable laser cutting embossing device according to the present invention. Figure 2 This is a schematic diagram of the ratchet mechanism of an adjustable laser cutting embossing device according to the present invention. Figure 1-2 As shown, an adjustable laser cutting embossing device according to a preferred embodiment is illustrated, comprising: a main shaft 1 for combined mounting with an embossing device adjustment rod and a fine-tuning motor of an existing laser cutting machine (i.e., the fine-tuning motor is connected to the main shaft 1 via the adjustment rod for transmission) and a plurality of embossing wheels 2 with different embossing patterns on the outside, each of the embossing wheels 2 being coaxially mounted on the outside of the main shaft 1 and rotatably mounted in one direction.

[0029] In this application, multiple embossing wheels 2 with different external embossing patterns are set, and each embossing wheel 2 can be unidirectionally rotated and mounted on the main shaft 1. Different embossing wheels 2 can be flexibly selected for embossing operations according to actual production needs, so as to realize a combination of various embossing shapes and methods, meet different process requirements, and improve the applicability and flexibility of the device.

[0030] Furthermore, as a preferred embodiment, each of the embossing wheels 2 is mounted on the main shaft 1 in a unidirectional rotatable manner via a one-way self-locking mechanism. The one-way self-locking mechanism ensures that the embossing wheel 2 can only rotate in one direction, and can stably maintain the set position and state during the embossing process, avoiding unstable embossing effect due to reverse rotation or accidental movement, and ensuring the uniformity and consistency of embossing quality.

[0031] Furthermore, as a preferred embodiment, the one-way self-locking mechanism is a ratchet mechanism 3. The ratchet mechanism 3 has a simple structure, reliable operation, and can effectively realize one-way rotation and self-locking functions. It has a relatively low cost and is easy to maintain and replace, reducing production costs and ease of use while ensuring device performance.

[0032] Furthermore, as a preferred embodiment, the ratchet 3 mechanism is an internal ratchet 3 mechanism, and is disposed between the inner wall of the embossing wheel 2 and the outer wall of the main shaft 1. By placing the internal ratchet 3 mechanism between the inner wall of the embossing wheel 2 and the outer wall of the main shaft 1, the internal space of the device is fully utilized, making the overall structure more compact, reducing the size and floor space of the device, and simultaneously improving the stability and reliability of the device.

[0033] Furthermore, as a preferred embodiment, the inner ratchet mechanism 3 includes a ratchet 3 and at least two pawls 4. The ratchet 3 is coaxially mounted on the inner wall of the embossing wheel 2, and the inner wall of the ratchet 3 is circumferentially provided with ratchet teeth 31. One end of each pawl 4 is rotatably connected to the main shaft 1, and the other end engages with the ratchet teeth 31 in a unidirectional self-locking engagement. Multiple pawls 4 engaging with the ratchet teeth 31 increases the reliability and stability of the self-locking mechanism and reduces the risk of self-locking failure due to the malfunction of a single pawl 4.

[0034] Of course, in another embodiment, in order to keep the pawl 4 in constant contact with the ratchet 31, an elastic element (such as a tension spring) is also connected between the pawl 4 and the outer wall of the spindle 1, so that the pawl 4 is always in elastic contact with the ratchet 31 by the elastic force of the tension spring.

[0035] Furthermore, as a preferred embodiment, the two pawls 4 are respectively located on both sides of the main shaft 1 along its radial direction. Positioning the two pawls 4 on both sides of the main shaft 1 along its radial direction allows for a more even distribution of the force exerted by the pawls 4 on the ratchet 3, further improving the stability and reliability of the self-locking mechanism, reducing vibration and noise during operation, and extending the service life of the device.

[0036] Furthermore, as a preferred embodiment, the ratchet 3 and the embossing wheel 2 are an integrated structure. This integrated design reduces the number of parts and assembly steps, improves the overall strength and rigidity of the device, avoids loosening and malfunctions caused by insecure parts connections, simplifies the production process, and reduces production costs.

[0037] Of course, in another embodiment, the ratchet 3 and the embossing wheel 2 can be designed separately and connected detachably with bolts. If one of the parts is damaged, only the damaged part needs to be replaced, reducing maintenance costs.

[0038] Furthermore, as a preferred embodiment, the ratchet 31 and the ratchet wheel 3 are an integrated structure. This integrated structure enhances the strength and wear resistance of the ratchet wheel 3, ensures the meshing accuracy and stability between the ratchet 31 and the pawl 4, reduces self-locking failures caused by wear or loosening of the ratchet 31, and improves the reliability and service life of the device.

[0039] Furthermore, as a preferred embodiment, two adjacent embossing wheels 2 are arranged in contact with each other. This contact arrangement between adjacent embossing wheels 2 ensures seamless connection during the embossing process, avoiding incomplete embossing or defects caused by gaps between the wheels, thus guaranteeing the continuity and integrity of the embossing and improving its quality.

[0040] Of course, in actual use, in order to adapt to the actual application needs, the two adjacent embossing wheels 2 can also be set at intervals.

[0041] Furthermore, as a preferred embodiment, the plurality of embossing wheels 2 are distributed at equal intervals along the axial direction of the main shaft 1. This equal distribution of the embossing wheels 2 along the axial direction of the main shaft 1 ensures uniform force distribution during the embossing process, guaranteeing the uniformity and consistency of the embossing effect. It also facilitates the installation, adjustment, and replacement of the embossing wheels 2, improving the ease of operation and maintenance efficiency of the device. Of course, to adapt to practical application needs, the plurality of embossing wheels 2 can also be arranged at unequal intervals along the axial direction of the main shaft.

[0042] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
