Obviously, the described embodiments are only some of the embodiments of the present application, rather than all the embodiments of the present application.

The phrase appears at various places in the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment to the other embodiments.

[0046] In the description of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "mounting", "connection", "connecting", "attachment" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integrally connected; it can be directly connected, or indirectly connected through an intermediate medium, or the internal communication of two elements.

[0047] The term "and / or" in the present application only describes the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B can mean that A exists alone, A and B exist together, and B exists alone.

[0048] In the embodiments of the present application, the same reference signs represent the same parts, and for the sake of brevity, the detailed description of the same parts is omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, as well as the overall thickness, length, width and other dimensions of the integrated device, are only exemplary and should not constitute any limitation on the present application.

[0049] "Multiple" appearing in the present application means two or more (including two).

[0050] In the following, the embodiments of the present application are described in detail.

[0051] There are multiple welding processes in the production process of the battery device, such as welding of key welding parts such as current collecting plate and current collector of battery monomer. In the welding process, a large amount of welding slag is easily generated. If these welding slags cannot be removed in time, they may be left on the surface of the current collecting plate. If the subsequent welding slag falls into the internal electrode sheet due to vibration, it will directly cause the occurrence of self-discharge phenomenon, which seriously threatens the electrochemical performance and safety of the battery monomer.

[0052] In related technologies, in order to remove the welding slag, the welding slag is directly scraped after welding. However, this method still cannot avoid the falling of the welding slag, and the welding slag is easy to scratch the surface of the current collecting plate when scraping, which may also fall into the internal electrode sheet, still causing negative impact on the performance of the battery monomer.

[0053] Therefore, how to reduce the possibility of falling of the welding slag after the battery is welded, and reduce the negative impact on the performance of the battery monomer in the process of removing the welding slag, is an important topic in the production and processing of the battery.

[0054] In view of this, the present application provides a technical scheme, which fixes the welding slag or completely removes the welding slag by dripping liquid on the welding slag, thereby solving the above technical problems.

[0055] The application will be described below in conjunction with the accompanying drawings Figures 1-6 The battery welding slag protection equipment 100 provided by the embodiment of the application is introduced.

[0056] The application will be described below in conjunction with the accompanying drawings Figures 1-4 As shown in the accompanying drawings, the application provides a battery welding slag protection equipment 100, which comprises an image acquisition device 10, a control device 20 and a liquid outlet device 30. The image acquisition device 10 is used to acquire image information of a welding work surface 210 of a battery structure. The control device 20 is electrically connected with the image acquisition device 10 and is used to acquire position information of welding slag on the welding work surface 210. The liquid outlet device 30 is used to provide liquid to the welding slag so as to fix the welding slag on the welding work surface 210 or remove the welding slag.

[0057] The battery welding slag protection equipment 100 of the embodiment can be applied to welding slag protection after welding of the battery structure, and can also be applied to welding slag protection during welding of the battery structure.

[0058] The battery structure can be a battery monomer 200, can also be a battery device, and can also be an electrode assembly, as long as it has a welding work surface 210 and belongs to the battery device or a part of the battery device. It can be understood as the battery structure of the embodiment. The embodiment takes the battery structure as the battery monomer 200 and the welding work surface 210 as the surface of the current collector disc of the battery monomer 200 as an example for description.

[0059] The battery device mentioned in the embodiment of the application refers to a single physical module comprising one or more battery monomers 200 to provide higher voltage and capacity. For example, the battery device mentioned in the application can comprise a battery module or a battery pack, etc. The battery generally comprises a battery box body for packaging one or more battery monomers 200. The battery box body can avoid the influence of liquid or other foreign matters on the charging or discharging of the battery monomer 200.

[0060] The battery monomer 200 mentioned in the embodiment of the application can be a lithium ion secondary battery monomer, a lithium ion primary battery monomer, a lithium-sulfur battery monomer, a sodium lithium ion battery monomer, a sodium ion battery monomer or a magnesium ion battery monomer, etc. The embodiment of the application is not limited thereto. The battery monomer 200 can be in the shape of a cylinder, a flat body, a cuboid or other shapes, etc. The embodiment of the application is not limited thereto.

[0061] The battery cell 200 mentioned in the embodiments of the present application can include an electrode assembly and an electrolyte, and the electrode assembly includes a positive electrode tab, a negative electrode tab, and a separator. The battery cell 200 mainly relies on the movement of metal ions between the positive electrode tab and the negative electrode tab to work. The positive electrode tab includes a positive electrode current collector and a positive electrode active material layer coated on the surface of the positive electrode current collector; the positive electrode current collector includes a positive electrode coating area coated with the positive electrode active material layer and a positive electrode tab connected to the positive electrode coating area, and the positive electrode tab is not coated with the positive electrode active material layer.

[0062] Taking the lithium-ion battery cell 200 as an example, the material of the positive electrode current collector can be aluminum, and the positive electrode active material layer includes a positive electrode active material, which can be lithium cobaltate, lithium iron phosphate, ternary lithium, or lithium manganate, etc. The negative electrode tab includes a negative electrode current collector and a negative electrode active material layer coated on the surface of the negative electrode current collector; the negative electrode current collector includes a negative electrode coating area coated with the negative electrode active material layer and a negative electrode tab connected to the negative electrode coating area, and the negative electrode tab is not coated with the negative electrode active material layer. The material of the negative electrode current collector can be copper, and the negative electrode active material layer includes a negative electrode active material, which can be carbon or silicon, etc. The material of the separator can be PP (polypropylene) or PE (polyethylene), etc.

[0063] The image acquisition device 10 is a structure capable of acquiring image information of the welding work surface 210, and transmitting the acquired image information to the control device 20, for example, the image acquisition device 10 can be a CCD camera, a CMOS camera, a laser scanner, a structured light 3D camera, an ultrasonic imaging device, etc., and this embodiment does not enumerate too much.

[0064] Taking the image acquisition device 10 as a CCD camera as an example, the CCD camera has high resolution and wide dynamic range, and can clearly capture the details of the welding work surface 210, thereby providing more accurate image information for the control device 20.

[0065] The control device 20 is a structure capable of receiving the image information transmitted by the image acquisition device 10, and processing the image information to obtain the position information of the welding slag, for example, the control device 20 can include a PLC (programmable logic controller), an industrial computer, a cloud server, a single-chip microcomputer, etc.

[0066] Taking the control device 20 including a PLC as an example, it can perform a defect recognition algorithm, automatically recognize defects such as welding slag protrusions and surface scratches through an image processing algorithm, and generate coordinate data of the welding slag, and use the coordinate data to send control instructions to the liquid outlet device 30, so that the liquid outlet device can perform liquid drop processing on each welding slag on the welding work surface 210.

[0067] The liquid discharging device 30 is a structure capable of dripping liquid on each welding slag on the welding work surface 210. The control device 20 can control the amount of liquid dripping of the liquid discharging device 30, so that the amount of each liquid drop matches the size of the welding slag, so as to better fix the welding slag or remove the welding slag, thereby reducing the possibility of subsequent falling of the welding slag, and thereby reducing the impact on the battery structure (for example, the battery monomer 200).

[0068] Again, in combination with the accompanying Figures 1-4 As shown, in some examples, the liquid discharging device 30 includes a first moving mechanism 31 and a liquid discharging mechanism 32, the first moving mechanism 31 is connected with the liquid discharging mechanism 32 and is used to drive the liquid discharging mechanism 32 to move to discharge liquid.

[0069] The first moving mechanism 31 can be installed on a first rack (not shown in the figure), and the image acquisition device 10 can be installed on a second rack (not shown in the figure), or the first moving mechanism 31 and the image acquisition device 10 can be installed on the same rack.

[0070] The first moving mechanism 31 is used to drive the liquid discharging mechanism 32 to move, so that the liquid discharging mechanism 32 can be located directly above each welding slag, so as to drip liquid on each welding slag.

[0071] The first moving mechanism 31 can have various forms of structures, for example, it can be a mechanical arm, a Cartesian robot, a parallel robot, a carrying robot, etc., and this embodiment does not make too many enumerations.

[0072] In some examples, the first moving mechanism 31 includes a first linear motion assembly 311 and a second linear motion assembly 312, the first linear motion assembly 311 is connected with the second linear motion assembly 312, the first linear motion assembly 311 is used to drive the second linear motion assembly 312 to move along a first direction X, the second linear motion assembly 312 is connected with the liquid discharging mechanism 32, and the second linear motion assembly 312 is used to drive the liquid discharging mechanism 32 to move along a second direction Y, the first direction X and the second direction Y intersect and are respectively parallel to the welding work surface 210.

[0073] The first linear motion assembly 311 can be any kind of linear reciprocating assembly capable of moving along the first direction X, for example, it can be a combination of a servo motor / stepper motor+ball screw (high precision) / synchronous belt, or a combination of a motor+ball screw / gear rack, or a combination of a cylinder, an electric cylinder, and a hydraulic cylinder, etc.

[0074] The second linear motion assembly 312 has the same or similar structure as the first linear motion assembly 311. The first linear motion assembly 311 has a first moving part (not shown in the figure) moving along the first direction X. The second linear motion assembly 312 is installed on the first moving part and moves linearly along the first direction X with the first moving part.

[0075] The second linear motion assembly 312 has a second moving part (not shown in the figure). The liquid outlet mechanism 32 is installed on the second moving part and moves linearly along the second direction Y with the second moving part.

[0076] In some embodiments, the first direction X and the second direction Y are both horizontal directions and perpendicular to each other.

[0077] In the embodiment, the first moving mechanism 31 is designed to include the first linear motion assembly 311 and the second linear motion assembly 312. The first linear motion assembly 311 and the second linear motion assembly 312 can realize the movement of the liquid outlet mechanism 32 along the first direction X and the second direction Y, thereby improving the flexibility of the liquid outlet mechanism 32.

[0078] In some examples, the first moving mechanism 31 further includes a third linear motion assembly 313. The third linear motion assembly 313 is connected to the second linear motion assembly 312 and the liquid outlet mechanism 32, respectively, and is used to drive the liquid outlet mechanism 32 to move along a third direction Z. The third direction Z intersects the first direction X and the second direction Y, respectively.

[0079] In some embodiments, the third direction Z is a vertical direction. The third direction Z can be perpendicular to the first direction X and the second direction Y, respectively, so that the third linear motion assembly 313 can drive the liquid outlet mechanism 32 to approach or move away from the welding work surface 210 (elevation), thereby enabling the liquid outlet mechanism 32 to be closer to the welding slag, so that the liquid can directly wrap the welding slag, thereby achieving better welding slag protection or removal effect.

[0080] The third linear motion assembly 313 of the embodiment can have the same or similar structure as the first linear motion assembly 311 described above. For example, the third linear motion assembly 313 can be a linear reciprocating motion assembly such as a pneumatic cylinder, an electric cylinder, or a hydraulic cylinder. Therefore, the embodiment will not be described in more detail.

[0081] The third linear motion assembly 313 has a third moving part moving linearly along the third direction Z. The third moving part is used to drive the liquid outlet mechanism 32 to elevate.

[0082] In some examples, the liquid outlet mechanism includes a liquid outlet pump and a liquid outlet head. The liquid outlet pump is connected to the liquid outlet head for conveying liquid to the liquid outlet head. The liquid outlet head is used to provide liquid to the welding slag.

[0083] The above description is combined with the accompanyingFigure 1 and attached Figure 2 As shown in FIG. 1 and FIG. 2, in some embodiments, the liquid outlet mechanism 32 is a dispensing mechanism, which is used to drop glue on the welding slag, and the glue is used to fix the welding slag on the welding work surface 210.

[0084] The glue can be any liquid glue, for example, the glue can be epoxy glue, silicone glue, UV curing glue, etc., which will not be listed one by one in this embodiment.

[0085] In some embodiments, the liquid outlet device 30 can also be designed to include a curing lamp or other structure that helps the glue to cure (not shown in the figure) to improve the curing speed of the glue.

[0086] The liquid outlet mechanism 32 is designed as a dispensing mechanism, which uses the glue dropped by the dispensing mechanism to fix the welding slag, and the structure is simple and has good fixing effect on the welding slag, reducing the subsequent falling of the welding slag.

[0087] When the liquid outlet mechanism 32 is a dispensing mechanism, the liquid outlet pump at this time is a dispensing pump 321, and the liquid outlet head is a dispensing head 322. The dispensing pump 321 is connected to the first moving mechanism 31, the dispensing head 322 is connected and communicated with the dispensing pump 321, and the dispensing pump 321 is used to provide glue to the dispensing head 322.

[0088] The dispensing pump 321 is a pump body structure for providing stable glue output and controlling flow and pressure, which can be a plunger pump, a gear pump, a screw pump, or a pneumatic pump.

[0089] The dispensing head 322 is detachably mounted on the dispensing pump 321, and is a structure that can control the dispensing shape, which can spray glue in the form of points, lines or surfaces. The dispensing head 322 of the present embodiment can be in the form of a needle or a spray valve, as long as it can accurately deliver glue to the welding slag.

[0090] The dispensing pump 321 provides stable pressure to avoid dripping or broken glue. The dispensing head 322 can be replaced flexibly to adapt to different dispensing shapes (points, lines, surfaces) to meet high-precision or high-speed dispensing requirements, improve the reliability and yield of battery assembly. The combination of the dispensing pump 321 and the dispensing head 322 can accurately control the amount of glue, so that the glue is uniformly and stably output, which is suitable for different viscosity glues, and improves the dispensing efficiency and consistency.

[0091] Combined with attached Figure 3 and attached Figure 4 As shown in FIG. 1 and FIG. 2, in some embodiments, the liquid outlet mechanism 32 is a liquid droplet removal mechanism, which is used to drop a removal liquid on the welding slag, and the removal liquid is used to chemically corrode the welding slag.

[0092] In some embodiments, the liquid can be an acidic solution such as sulfuric acid, hydrochloric acid, phosphoric acid, nitric acid, etc.

[0093] Therefore, the material of the liquid outlet mechanism 32 needs to be selected to be a material that is not easily corroded by the acidic solution, such as glass, perfluoroalkoxy resin, polytetrafluoroethylene, etc.

[0094] In this embodiment, the liquid outlet mechanism 32 is designed as a liquid drop removal mechanism that can remove liquid drops. By using liquid chemical corrosion of the welding slag, the welding slag can be completely ablated, thereby further reducing the situation of falling welding slag.

[0095] In combination with FIGS. 1-3 Figure 3 and 4 When the liquid outlet mechanism 32 is a liquid drop removal mechanism, the liquid outlet pump is a corrosion-resistant drop pump 323, and the liquid outlet head is a corrosion-resistant drop head 324. The drop pump 323 is connected to the first moving mechanism 31, and the drop head 324 is connected to and communicates with the drop pump 323. The drop pump 323 is used to provide liquid to the drop head 324.

[0096] The drop pump 323 is a pump body that is resistant to corrosion by acidic solutions and is used to transport acidic liquids. The pump body, rotor, and sealing components of the drop pump 323 are made of strong acid-resistant materials, including PTFE (Teflon), PVDF, PFA, or Hastelloy. The drop pump 323 can be a plunger pump, a peristaltic pump, a diaphragm pump, or a gear pump, etc.

[0097] The drop head 324 is made of acid-resistant materials, such as a needle structure made of materials including PTFE, aluminum oxide ceramic, glass, etc.

[0098] The drop head 324 is detachably connected to the drop pump 323, and the connection between the two needs to be sealed with a corrosion-resistant seal.

[0099] The drop pump 323 can accurately control the amount of liquid flowing out of the drop head 324, such as controlling the output flow rate to be greater than or equal to 2 ml / s. In addition, the drop pump 323 can also be designed to have a back suction function to suck back the removed liquid remaining in the drop head 324 after the liquid drops.

[0100] In some examples, the liquid outlet mechanism further includes a liquid supply structure (not shown in the figures), which communicates with the liquid outlet pump. The liquid supply mechanism is used to store liquid and provide liquid for the liquid outlet pump. The liquid stored in the liquid supply mechanism is glue or a removal liquid. The glue is used to fix the welding slag on the welding work surface or to chemically corrode the welding slag.

[0101] The liquid supply structure and the liquid outlet pump can be connected by a pipeline or directly connected.

[0102] The liquid supply structure can be a liquid storage tank, a liquid outlet bottle or the like, which is used to store the removal liquid to provide the removal liquid for the liquid outlet pump.

[0103] In some examples, the battery welding slag protection device 100 further comprises a liquid suction device 40, which is used to adsorb the liquid on the welding work surface 210.

[0104] The reason for setting the liquid suction device 40 is that when the liquid outlet mechanism 32 is a removal liquid droplet mechanism, the removal liquid for chemically corroding the welding slag is usually an acidic liquid, which can easily cause corrosion burns on the welding work surface 210 while removing the welding slag.

[0105] Therefore, the liquid suction device 40 can be used to adsorb the removal liquid immediately after the liquid outlet device 30 performs a droplet of welding slag, and the liquid suction device 40 can reduce the corrosion degree of the liquid on the welding work surface 210 by adsorbing the liquid after corroding the welding slag.

[0106] In addition, when the liquid outlet mechanism 32 is a dispensing mechanism, the liquid suction device 40 can be used to adsorb excess glue.

[0107] The liquid suction device 40 can be installed with the liquid outlet device 30 on one rack, or the two can be installed on different racks, which will not be limited in this embodiment.

[0108] In some examples, the liquid suction device 40 comprises a second moving mechanism 41 and a liquid suction mechanism 42, the second moving mechanism 41 is connected with the liquid suction mechanism 42 and is used to drive the liquid suction mechanism 42 to move to suck the liquid.

[0109] The second moving mechanism 41 can be a mechanical arm, a mechanical arm, a Cartesian robot, a parallel robot or the like, as long as it can drive the liquid suction mechanism 42 to adsorb the liquid, and the specific structure form will be given below.

[0110] The liquid suction mechanism 42 is a mechanism capable of generating adsorption negative pressure, which is used to adsorb and collect the liquid after the liquid droplet head 324 drops the liquid on the welding slag, and then corrodes and ablates the welding slag, so as to reduce the corrosion of the liquid on the welding work surface 210.

[0111] In some examples, the second moving mechanism 41 comprises a fourth linear motion assembly 411, a fifth linear motion assembly 412, and a sixth linear motion assembly 413. The fourth linear motion assembly 411 is connected to the fifth linear motion assembly 412 and configured to drive the fifth linear motion assembly 412 to move along the first direction X. The fifth linear motion assembly 412 is connected to the sixth linear motion assembly 413 and configured to drive the sixth linear motion assembly 413 to move along the second direction Y. The sixth linear motion assembly 413 is connected to the liquid suction mechanism 42 and configured to drive the liquid suction mechanism 42 to move along the third direction Z. The first direction X and the second direction Y are perpendicular to each other and parallel to the welding work surface 210. The third direction Z is perpendicular to the first direction X and the second direction Y.

[0112] The fourth linear motion assembly 411, the fifth linear motion assembly 412, and the sixth linear motion assembly 413 can have the same or similar structure as the first linear motion assembly 311 described above. For details, please refer to the description of the first linear motion assembly 311.

[0113] The fourth linear motion assembly 411 has a fourth moving part moving along the first direction X, and the fifth linear motion assembly 412 is installed on the fourth moving part. The fifth linear motion assembly 412 has a fifth moving part moving along the second direction Y, and the sixth linear motion assembly 413 is installed on the fifth moving part. The sixth linear motion assembly 413 has a sixth moving part moving along the third direction Z, and the liquid suction mechanism 42 is installed on the sixth moving part.

[0114] The fourth linear motion assembly 411, the fifth linear motion assembly 412, and the sixth linear motion assembly 413 drive the liquid suction mechanism 42 to move along the first direction X, the second direction Y, and the third direction Z, which improves the flexibility of the liquid suction mechanism 42 and makes it more convenient for the liquid suction mechanism 42 to perform the liquid suction action.

[0115] In some examples, the liquid suction mechanism 42 comprises a liquid suction pump 421 and a liquid suction head 422. The liquid suction pump 421 is installed on the second moving mechanism 41, and the liquid suction head 422 is connected to and communicates with the liquid suction pump 421. The liquid suction pump 421 is configured to generate a negative pressure for the liquid suction head 422 to suck liquid.

[0116] The liquid suction pump 421 can be a diaphragm pump, a peristaltic pump, a centrifugal pump, a vacuum liquid suction pump 421, etc. It can suck liquid under negative pressure and discharge the sucked liquid.

[0117] The liquid suction head 422 is a negative pressure suction execution component, one end of which is connected and communicated with the liquid suction pump 421, and the other end is designed as a porous or slit structure to expand the suction area. The internal flow channel of the liquid suction head 422 is optimized to reduce liquid residue, and some models are integrated with anti-dripping valves. The liquid suction head 422 can be connected with the liquid suction pump 421 through a corrosion-resistant quick-release interface.

[0118] Both the liquid suction pump 421 and the liquid suction head 422 are made of corrosion-resistant materials such as glass, perfluoroalkoxy resin, and polytetrafluoroethylene.

[0119] The liquid suction mechanism 42 is designed to include the liquid suction pump 421 and the liquid suction head 422, which provides negative pressure for the liquid suction head 422, and the liquid suction head 422 performs liquid suction, which is simple in structure and easy to implement.

[0120] In combination with the accompanying Figure 5 As shown in some examples, the liquid suction device 40 also includes a waste liquid collection mechanism 43 connected and communicated with the liquid suction mechanism 42, and the waste liquid collection mechanism 43 is used to collect the liquid sucked by the liquid suction mechanism 42.

[0121] The waste liquid collection mechanism 43 can include a collection pipeline 431 and a collection container 432, one end of the collection pipeline 431 being communicated with the liquid suction pump 421, and the other end of the collection pipeline 431 being communicated with the collection container 432.

[0122] After the liquid suction pump 421 collects the waste liquid, the liquid suction pump 421 discharges the waste liquid to the collection container 432 through the collection pipeline 431 for recycling, reduces the possibility of environmental pollution of the waste liquid, and can reuse the recycled waste liquid, saving energy and protecting the environment.

[0123] In combination with the accompanying Figure 6 As shown in some embodiments, the control device 20 of the present embodiment can be electrically connected with the image acquisition device 10, the liquid outlet device 30, and the liquid suction device 40 respectively. The "electrical connection" means that the two are connected in communication through wireless signals (WIFI, Bluetooth, etc.), or are conductively connected through wires.

[0124] Specifically, the control device 20 can be electrically connected with the image acquisition device 10, the first moving mechanism 31, the liquid outlet mechanism 32, the second moving mechanism 41, and the liquid suction mechanism 42 respectively.
