These terms are only used to distinguish the same type of information from each other.

Depending on the context, the words "if" and "if" as used herein may be interpreted as "at" or "when" or "in response to determination".

[0044] In addition, various forms of processes shown in the embodiments of the present disclosure may be used to reorder, add or delete steps. For example, the steps described in the present application may be performed in parallel, sequentially or in different orders, as long as the desired results of the technical solution disclosed in the present application can be achieved, and this document does not limit this.

[0045] In the related art, for large-area thin-film battery modules, in order to enable the thin-film battery modules to output voltage and current that meet the requirements, the thin-film battery modules need to be scratched by laser or mechanical scratching. However, the traditional scratching method is to use a single laser beam to scratch the film surface or to scratch through glass. The thermal effect of the film surface after scratching in this way is serious, resulting in a "crater". Since scratching through glass is an explosive scratching, this method of scratching through glass will produce an edge explosion phenomenon, resulting in a short circuit between the upper and lower electrodes of the PN junction.

[0046] In order to solve the above problems, the present disclosure provides a battery component scratching method, device and system, which obtains the target scratching data of the battery component to be scratched, determines the scratching path according to the target scratching data, controls the first laser head to scratch the substrate of the battery component to be scratched according to the scratching path, controls the second laser head to scratch the film layer of the battery component to be scratched according to the scratching path, and the first laser head and the second laser head operate synchronously, or, for the same two-dimensional coordinate point on the scratching path, the scratching time node of the first laser head is before the scratching time node of the second laser head. By controlling the first laser head and the second laser head to operate synchronously, the thermal effect on the film surface can be effectively reduced, and the edge frying phenomenon when scratching the glass substrate can be avoided, thereby improving the quality of the scratched battery component.

[0047] Figure 1 is a flow chart of a battery component scribing method according to an exemplary embodiment. Figure 1 As shown, it should be noted that the battery component scribing method of the embodiment of the present application is applied to a battery component scribing device. Figure 1 As shown, the method may include the following steps:

[0048] Step 101, obtaining target scribing data of a battery assembly to be scribed.

[0049] In one embodiment, the target scribing data may be a pattern that needs to be scribed on the battery component to be scribed.

[0050] Step 102, determining a scribing path according to the target scribing data.

[0051] It is understandable that in order to control the first laser head 1 and the second laser head 2 to scribe the required pattern on the battery assembly to be scribed, it is necessary to determine the points to be scribed according to the target scribe data.

[0052] Therefore, a scribing path may be determined according to the target scribing data, and the scribing path may include the relative position coordinates of each point on the battery assembly to be scribed.

[0053] Step 103, controlling the first laser head 1 to perform scribing on the substrate 3 of the battery assembly to be scribed according to the scribing path.

[0054] The substrate 3 may be made of glass.

[0055] It is understandable that if Figure 2 and Figure 3 As shown, the battery assembly to be scribed includes a substrate 3 and a film layer 4, and the substrate 3 and the film layer 4 are bonded together. It is necessary to perform transparent scribing on the substrate 3 (that is, to scribe the film layer through the glass substrate), and to perform film surface scribing on the film layer 4 to form an etched groove 8.

[0056] In some embodiments of the present application, step 103 may specifically include:

[0057] The first vertical linear motor 6 and the first transverse linear motor 7 are controlled to operate according to the scribing path, so that the first laser head 1 mounted on the first transverse linear motor 7 moves according to the scribing path; the first transverse linear motor 7 is mounted on the first vertical linear motor 6 .

[0058] Step 104, controlling the second laser head 2 to perform scribing on the film layer 4 of the battery assembly to be scribed according to the scribing path.

[0059] It should be noted that due to the serious thermal effect of the film surface after scratching the film surface with a single laser beam, a "crater" is generated; since scratching through glass is an explosive scratching method, this method of through scratching will cause edge bursting, resulting in a short circuit between the upper and lower electrodes of the PN junction. Therefore, the present application uses a double-sided laser to scratch the battery assembly to be scratched. In this method, since the same point on the battery assembly to be scratched is acted upon by two laser beams from opposite directions, the laser energy required to achieve the same scratching result (that is, the same pattern) is smaller than that with a single laser beam, that is, the energy distribution received by the battery assembly to be scratched is more uniform, thereby effectively avoiding the generation of "craters" and edge bursting.

[0060] In one embodiment, the first laser head 1 and the second laser head 2 operate synchronously.

[0061] In another embodiment, for the same two-dimensional coordinate point on the scribing path, the scribing time node of the first laser head 1 is before the scribing time node of the second laser head 2 .

[0062] In some embodiments of the present application, the laser energy of the first laser head 1 is smaller than the laser energy of the second laser head 2 .

[0063] It can be understood that since there is a strong adhesion between the film layer 4 and the substrate 3, the first laser head 1 can be used to scratch the substrate 3 first, so as to remove the adhesion while scratching the substrate 3, and then the second laser head 2 can be used to scratch the film layer 4. In this way, the required scratching effect can be achieved while using a smaller laser energy, and severe thermal effects and edge bursting that cause short circuits between the upper and lower electrodes of the motor PN junction can be avoided.

[0064] In one embodiment, a relatively small laser beam can be used to perform penetration scoring on the substrate 3, and a relatively large laser beam can be used to perform surface scoring on the film layer 4, which can ensure both the penetration effect of the substrate 3 and the surface scoring effect of the film layer 4, thereby avoiding edge blasting on the substrate 3, and avoiding the problem of a "crater" caused by severe thermal effects on the film layer 4, and also avoiding the problem of uneven scoring position of the film layer 4.

[0065] As an example, the first laser head 1 can be used to emit a smaller laser energy to scratch the substrate 3, thereby removing the adhesion between the film layer 4 and the substrate 3, and then the second laser head 2 can be used to emit a larger laser energy to scratch the film layer 4. This can also avoid the problems of edge bursting of the substrate 3 and serious thermal effects of the film layer 4 to a certain extent.

[0066] As another example, while a first laser head 1 is used to emit a smaller laser energy to scribe a target two-dimensional scribe point on the substrate 3, a second laser head 2 is used to emit a larger laser energy to scribe the same target two-dimensional scribe point on the film layer 4, so that the energy absorbed by the thin-film battery component at the target point is relatively uniform and gentle. Compared with unilateral scribing, the problems of edge bursting of the substrate 3 and severe thermal effects of the film layer 4 can be effectively avoided.

[0067] In some embodiments of the present application, step 104 may specifically include:

[0068] The second vertical linear motor 10 and the second transverse linear motor 9 are controlled to operate according to the scribing path, so that the second laser head 2 mounted on the second transverse linear motor 9 moves according to the scribing path; the second transverse linear motor 9 is mounted on the second vertical linear motor 10 .

[0069] In some embodiments of the present application, the battery assembly to be scribed is arranged vertically, the first laser head 1 is arranged on the side of the battery assembly to be scribed close to the substrate 3, and the second laser head 2 is arranged on the side of the battery assembly to be scribed close to the film layer 4.

[0070] In some embodiments, the first vertical motor and the second vertical motor can be installed on the operating platform through their respective corresponding substrates 3, and a clamp is used to fix the battery assembly to be engraved between the first vertical motor and the second vertical motor, that is, to fix it between the first laser head 1 and the second laser head 2. The substrate 3 of the battery assembly to be engraved is close to the first laser head 1, and the film layer 4 is close to the second laser head 2.

[0071] like Figure 4 and Figure 5 As shown, in one embodiment, the first vertical motor includes two first sub-vertical motors, the two first sub-vertical motors are arranged at intervals, and are both installed on a base 5, the base 5 is fixedly connected to the operating platform, a first transverse linear motor 7 is connected between the two vertical motors, the first transverse motor can move up and down under the transmission of the two first vertical motors, and the first laser head 1 is installed on the transmission component of the first transverse motor; the second vertical motor includes two second sub-vertical motors, the two second sub-vertical motors are arranged at intervals, and are both installed on a base 5, the base 5 is fixedly connected to the operating platform, a second transverse linear motor 9 is connected between the two vertical motors, the second transverse motor can move up and down under the transmission of the two second vertical motors, and the second laser head 2 is installed on the transmission component of the second transverse motor.

[0072] According to the battery component scratching method proposed in the embodiment of the present application, by obtaining the target scratching data of the battery component to be scratched, determining the scratching path according to the target scratching data, controlling the first laser head to scratch the substrate of the battery component to be scratched according to the scratching path, and controlling the second laser head to scratch the film layer of the battery component to be scratched according to the scratching path, the first laser head and the second laser head operate synchronously, or, for the same two-dimensional coordinate point on the scratching path, the scratching time node of the first laser head is before the scratching time node of the second laser head. By controlling the first laser head and the second laser head to operate synchronously, the thermal effect on the film surface can be effectively reduced, and the edge blasting phenomenon when scratching a glass substrate can be avoided, thereby improving the quality of the scratched battery component.
