[0002] With the rapid development of thin-film batteries, laser scribing equipment and related edge cleaning and dust removal equipment have also been widely used. Among them, the problem of residual dust after laser scribing and edge cleaning has always attracted much attention, because the dust residue contains perovskite dust, dust from each transmission layer and even electrode layer. If there is too much dust residue after scribing or edge cleaning, it will affect the final performance and stability of the battery.

[0026] Embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0027] like Figure 1 and Figure 2 As shown, the dust removal and blowing device for a thin film battery 100 according to an embodiment of the present invention comprises: a base 1 , a moving component 2 and a dust removal component 3 .

[0028] The base 1 is used to place the thin film battery 100. The moving component 2 is connected to the base 1, and at least part of the moving component 2 is along the length direction of the base 1 (such as Figure 1 ) and the width direction (as shown in Figure 1 The dust removal component 3 is connected to the moving part, and includes a purge component 31 and a dust suction component 32. The purge component 31 is arranged adjacent to the thin film battery 100, and has a purge port for blowing toward the thin film battery 100. The dust suction component 32 has a dust suction port, and the dust suction port is arranged adjacent to the purge port so that the dust suction component 32 can absorb the purged dust.

[0029] Specifically, Figure 1 and Figure 2 As shown, the base 1 can usually be fixed on the operating table to carry and position the thin film battery 100, ensuring that the thin film battery 100 remains fixed during the processing. The moving component 2 is installed on the base 1 and can move in the front-to-back direction or the left-to-right direction according to the operation requirements. The dust removal component 3 is fixed on the moving component 2 and can move on the base 1 with the moving component 2 so as to operate different areas on the battery surface.

[0030] It is understandable that the moving component 2 can be a guide rail or a rolling device, so that the dust removal component 3 can move stably and accurately on the base 1. The purge member 31 is provided with a purge port for blowing airflow to the surface of the thin film battery 100 in a directional manner to blow up the dust on the surface of the thin film battery 100. The purge member 31 is located adjacent to the thin film battery 100, and the purge direction and intensity can be accurately controlled. The dust suction member 32 is provided with a dust suction port, which is located adjacent to the purge port so as to absorb the blown dust immediately after the purge. The dust suction member 32 is connected to a vacuum pump or a similar dust suction system to generate sufficient suction to remove dust.

[0031] That is to say, the dust removal and blowing device for thin-film battery 100 of the embodiment of the present invention can utilize the precise control of mobile component 2 to enable dust removal component 3 to be accurately positioned at a designated position of thin-film battery 100 to perform partial or overall dust removal. The combination of blowing and dust suction allows dust to be sucked away immediately after being blown up, which can effectively remove dust on the surface of thin-film battery 100, improve dust removal efficiency, and reduce cleaning problems caused by electrostatic adsorption.

[0032] In some embodiments, the purge member 31 includes a purge drive member 311 and a purge pipeline 312 , and the purge drive member 311 is connected to the purge pipeline 312 .

[0033] It is understandable that if Figure 1 and Figure 2 As shown, the purge drive 311 is a power source, which is responsible for generating sufficient airflow to drive the air flow in the purge pipeline 312. Optionally, the purge drive 311 can be a compressed air supply device, a fan or other airflow generating device. The purge pipeline 312 is a pipeline system connected to the purge drive 311, which is responsible for transmitting the airflow generated by the purge drive 311 to the purge port, so as to purge and clean the surface of the thin film battery 100.

[0034] That is, the purge drive 311 and the purge pipeline 312 work together to provide a stable and strong airflow, thereby improving the cleaning effect on the surface of the thin-film battery 100. By optimizing the design of the purge pipeline 312, the distribution and intensity of the airflow can be more accurately controlled to ensure uniform purge of the surface of the thin-film battery 100.

[0035] In some embodiments, the purge pipeline 312 includes a purge section 3121 and a purge expansion section 3122, the purge section 3121 is connected between the purge drive 311 and the purge expansion section 3122, and the cross-street area of ​​the purge expansion section 3122 gradually increases along the flow direction of the purge gas flow in the purge pipeline 312.

[0036] It is understandable that if Figure 1 and Figure 2As shown, the purge section 3121 is a part of the purge pipeline 312, and the purge section 3121 is connected between the purge drive 311 and the purge expansion section 3122 to transmit the airflow generated by the purge drive 311. The diameter of the purge section 3121 is smaller than the diameter of the purge expansion section 3122 to ensure that the airflow has a higher speed. The purge expansion section 3122 is located at the end of the purge section 3121, and its cross-sectional area gradually increases along the flow direction of the purge airflow, so that when the airflow passes through the purge expansion section 3122, the speed will decrease, while the pressure will increase.

[0037] That is to say, the purge section 3121 is seamlessly connected to the purge expansion section 3122. When the airflow enters the purge expansion section 3122 from the purge section 3121, the dynamic pressure of the airflow is converted into a static pressure due to the increase in the cross-sectional area, which is conducive to the airflow producing a more uniform and gentle purge effect at the purge port. By gradually expanding the cross-sectional area, the purge expansion section 3122 can reduce the speed of the airflow and increase the pressure of the airflow, thereby forming a more effective purge force at the purge port. In addition, in the purge expansion section 3122, the reduction in airflow speed and the increase in pressure help to more effectively remove dust on the surface of the thin film battery 100, while reducing the risk of damage to the surface of the thin film battery 100.

[0038] In some embodiments, the purge pipeline 312 further includes a purge bending section 3123 , which is connected between the purge section 3121 and the purge expansion section 3122 , and the purge bending section 3123 is bendable relative to the purge section 3121 .

[0039] It is understandable that if Figure 1 and Figure 2 As shown, the purge bending section is located between the purge section 3121 and the purge expansion section 3122. The purge bending section can be bent relative to the purge section 3121, which increases the flexibility of the purge pipeline 312. In other words, the purge bending section can be bent and adjusted according to the actual use environment, so that the position of the purge port can be changed with the bending of the purge bending section, so that the purge pipeline 312 can adapt to complex working environments and thin-film batteries 100 of different shapes, increasing the applicability of the device. By adjusting the purge bending section, the operator can more accurately control the direction of the purge airflow to achieve directional purge of a specific area of ​​the thin-film battery 100.

[0040] It should be noted that the purge bending section 3123 can be made of a material with good flexibility, such as a stainless steel bellows.

[0041] In some embodiments, the purge drive 311 includes an ion blower. It is understandable that when the electrostatic adsorption on the thin film battery 100 is strong and ordinary blowing cannot remove the dust on the thin film battery 100, the ion blower can be turned on for auxiliary purge to eliminate the influence of static electricity and speed up the dust removal efficiency.

[0042] In some embodiments, the dust collecting member 32 includes a dust collecting drive and a dust collecting pipeline 322, and the dust collecting drive is connected to the dust collecting pipeline 322. It can be understood that the dust collecting drive is the power source of the dust collecting assembly, and optionally, the dust collecting drive can be a vacuum pump or a fan, which is responsible for generating negative pressure, thereby sucking air and dust through the dust collecting pipeline 322. The dust collecting pipeline 322 connects the dust collecting drive and the dust collecting port, and is a channel for transmitting dust from the sweeping area to the collection point.

[0043] That is, the negative pressure provided by the dust suction drive can quickly suck in dust and transport the dust to the collection system through the dust suction pipeline 322, thereby ensuring the effect of edge cleaning and dust removal. Timely dust suction can reduce the suspension time of dust in the air and reduce the risk of dust spreading to the surrounding environment.

[0044] In some embodiments, the dust suction pipeline 322 includes a dust suction section 3221 and a dust suction expansion section 3222, the dust suction section 3221 is connected between the dust suction drive member and the dust suction expansion section 3222, and the cross-street area of ​​the dust suction expansion section 3222 gradually decreases along the flow direction of the dust suction airflow in the dust suction pipeline 322.

[0045] It is understandable that if Figure 1 and Figure 2 As shown, the dust suction expansion section 3222 is located at the end of the dust suction section 3221, and the cross-sectional area of ​​the dust suction expansion section 3222 gradually decreases along the flow direction of the dust suction airflow, which helps to increase the flow rate of the airflow during the dust suction process, while reducing the pressure, so that the dust is more easily sucked in and transmitted. In other words, since the cross-sectional area of ​​the dust suction expansion section 3222 gradually decreases, according to the principles of fluid mechanics, the airflow velocity will increase in the expansion section, which helps to improve the dust suction efficiency and make the dust easier to be sucked in. In addition, by optimizing the airflow characteristics, the dust suction assembly can collect and remove dust more effectively and improve the overall edge cleaning and dust removal performance. Since the airflow speed in the dust suction expansion section 3222 increases, the dust suction efficiency can be improved without increasing the load on the dust suction drive, thereby reducing energy consumption. The optimized design of the dust suction pipeline 322 reduces the risk of blockage and wear and reduces the maintenance requirements of the system.

[0046] Preferably, the radial dimension of the purge port is smaller than the radial dimension of the dust suction port, so that the dust blown by the purge port can be collected by the dust suction port.

[0047] In some embodiments, the dust suction pipeline 322 further includes a dust suction bending section 3223 , which is connected between the dust suction section 3221 and the dust suction expansion section 3222 , and the dust suction bending section 3223 is bendable relative to the dust suction section 3221 .

[0048] It is understandable that if Figure 1 and Figure 2 As shown, the dust suction bending section is located between the dust suction section 3221 and the dust suction expansion section 3222. The dust suction bending section can be bent relative to the dust suction section 3221, which increases the flexibility of the dust suction pipeline 322. In other words, the dust suction bending section can be bent and adjusted according to the actual use environment, so that the position of the dust suction port can be changed with the bending of the dust suction bending section, so that the dust suction pipeline 322 can adapt to complex working environments and thin-film batteries 100 of different shapes, thereby increasing the applicability of the device. Through the adjustment of the dust suction bending section 3223, the dust suction expansion section 3222 can more easily collect the raised dust, thereby improving the applicability of the dust suction pipeline 322.

[0049] It should be noted that the dust suction bending section 3223 can be made of a material with good flexibility, such as a stainless steel bellows.

[0050] In some embodiments, the moving component 2 includes a first moving member 21 and a second moving member 22, the first moving member 21 is connected to the base 1 and the first moving member 21 is movable along the width direction of the base 1, the second moving member 22 is connected to the first moving member 21 and the second moving member 22 is movable along the length direction of the base 1, and the dust removal component 3 is connected to the second moving member 22.

[0051] It is understandable that if Figure 1 and Figure 2 As shown, the first moving member 21 includes a first moving body 211 and a first rail 212. The first moving body 211 is adapted to the first rail 212. The first moving body 211 can move along the extension direction of the first rail (i.e. Figure 1 The second movable member 22 includes a second movable body 221 and a second track 222. The extension direction of the second track 222 is consistent with the left-right direction. The second movable body 221 is adapted to the second track 222 so that the second movable body 221 can move on the second track 222. The dust removal component 3 is connected to the second movable body 221.

[0052] That is, the dust removal and blowing device for thin-film battery 100 of the embodiment of the present invention can cover the entire surface of thin-film battery 100 by moving in two directions, thereby improving the comprehensiveness of edge cleaning and dust removal. The design of the double moving parts allows the position of the dust removal component 3 to be controlled more accurately, which helps to accurately clean specific areas. The design of the moving component 2 enhances the flexibility of the entire device, enabling it to adapt to thin-film batteries 100 of different sizes and shapes, as well as different working environments.

[0053] In some embodiments, the moving assembly 2 further includes a third moving member 23, the third moving member 23 is connected to the first moving member 21, and the third moving member 23 is used to drive the first moving member 21 to move along the height direction of the base 1 (such as Figure 1 Move in the up and down directions.

[0054] It is understandable that if Figure 1 and Figure 2 As shown, the third moving member 23 is connected to the first moving member 21 , that is, the third moving member 23 can drive the upper part of the first moving member 21 to move in the up and down direction, so as to adjust the distance between the dust removal assembly 3 and the surface of the thin film battery 100 .

[0055] It should be noted that the third moving member 23 can be a device with a linear reciprocating function such as a cylinder or an oil cylinder, so as to drive the upper part of the first moving member 21 to move.
