[0058] To better understand the embodiments of this application, the following is combined with... Figures 1 to 10 The embodiments of this application will be described in detail.

[0059] like Figures 1 to 9As shown, this application provides a battery welding apparatus 1, which includes a positioning component 11, a welding component 12, and a dust collection component 13. The welding component 12 is disposed on one side of the positioning component 11 and includes a laser emitter 121 facing the positioning component 11. The dust collection component 13 is disposed between the positioning component 11 and the welding component 12, and includes a through welding channel 131, a dust collection section 132, and a dust collection channel 133 communicating with the dust collection section 132.

[0060] Battery 3 can be a lithium-ion battery, lithium-sulfur battery, sodium-lithium-ion battery, sodium-ion battery, or magnesium-ion battery, etc., and this application embodiment does not limit this. The shape of battery 3 can be cylindrical, flat, cuboid, or other shapes, etc., and this application embodiment also does not limit this. Figure 4 and Figure 6 As shown, in some embodiments, the battery 3 includes a cap 31 and a housing 32. The cap 31 covers one end of the housing 32. The battery welding device 1 is used to weld the cap 31 and the housing 32 together to form a sealed space inside the battery 3. This prevents leakage of the electrolyte inside the battery 3 and avoids external moisture and other impurities from entering the battery 3 and affecting its normal operation. Of course, the battery welding device 1 can also be used to weld other components of the battery 3, and this application embodiment does not limit this application.

[0061] The positioning component 11 is a component used to fix the battery 3. The positioning function of the positioning component 11 can ensure that the battery 3 has a certain relative position in the battery welding device 1, thereby ensuring that the laser emitted by the laser emitter 121 can accurately act on the part of the battery 3 to be welded, and ensuring the welding quality of the battery 3.

[0062] The welding assembly 12 includes a laser emitter 121, which emits a laser to melt and weld the parts of the battery 3 to be welded together. The laser emitter 121 is positioned toward the positioning assembly 11 to ensure that the laser emitter 121 is aligned with the battery 3 positioned on the positioning assembly 11, so that the laser emitted by the laser emitter 121 can act on the parts of the battery 3 to be welded.

[0063] The dust extraction component 13 is positioned between the positioning component 11 and the welding component 12. During the welding process of the battery 3, the dust extraction component 13 can promptly extract the smoke, welding slag and other dust generated during the welding process to ensure the welding quality of the battery 3.

[0064] The welding channel 131 passes through the dust collection assembly 13 to ensure that the laser generated by the laser emitter 121 can pass through the welding channel 131 and act on the battery 3, thereby further ensuring the welding quality of the battery 3.

[0065] The suction channel 133 is a component that provides negative pressure for the suction assembly 13. The suction channel 133 connects the external negative pressure device and the suction part 132, and delivers the negative pressure generated by the negative pressure device to the surface of the suction part 132 near the battery 3, thereby timely extracting the smoke and dust impurities during the welding process.

[0066] By setting up the dust extraction component 13, the fumes and welding slag generated during the welding process can be extracted, which can prevent the welding slag from falling and contaminating the surface of the battery 3, and also prevent the generated fumes from blocking the laser and affecting the welding quality, thereby improving the welding quality of the battery 3.

[0067] like Figure 7 As shown, in some embodiments, the suction section 132 is formed by the suction assembly 13 being recessed inward toward the surface of the positioning assembly 11.

[0068] By recessing the suction assembly 13 inward toward the surface of the positioning assembly 11 to form the suction section 132, the suction section 132 can be placed on one side of the battery 3. In this way, the suction section 132 can not only cover the battery 3, but also make the suction channel 133 as close as possible to the welding part of the battery 3, thereby improving the dust removal effect during the welding process of the battery 3.

[0069] like Figure 7 As shown, in some embodiments, the dust suction unit 132 is formed by a bottom wall 1321 and a side wall 1322 disposed on one side of the bottom wall 1321, and at least one of the side walls 1322 is inclined.

[0070] The suction section 132 is recessed inward by means of the bottom wall 1321 and the side wall 1322 surrounding the bottom wall 1321, so that the battery 3 can be housed inside the suction section 132.

[0071] At least one of the side walls 1322 is inclined, that is, the angle between at least one of the side walls 1322 and the bottom wall 1321 is greater than 90° and less than 180°.

[0072] By tilting at least one of the sidewalls 1322 to gradually enlarge the opening of the suction section 1322, that is, the suction section 1322 is formed into a trumpet shape, the area of ​​the concave surface of the suction section 1322 can be increased, thereby increasing the suction area and improving the dust removal effect of the battery welding device 1.

[0073] like Figures 1 to 6 As shown, in some embodiments, the battery welding apparatus 1 further includes an air blowing assembly 14, which is disposed on the side of the positioning assembly 11 opposite to the dust suction assembly 13.

[0074] The gas blowing assembly 14 refers to a component capable of supplying gas to the battery welding device 1. In some embodiments, the gas blown out by the gas blowing assembly 14 may be a protective gas such as helium to increase the welding quality of the battery 3.

[0075] The air blowing component 14 is positioned on the positioning component 11 away from the dust suction component 13. That is, the air blowing component 14 and the dust suction component 13 are located on opposite sides of the positioning component 11. In this way, the air blown out by the air blowing component 14 can flow to the dust suction component 13 under the negative pressure of the dust suction component 13, thereby forming an airflow between the air blowing component 14 and the dust suction component 13. This more effectively draws the smoke and dust impurities generated during the welding process of the battery 3 into the dust suction component 13, thereby improving the dust removal effect of the battery welding device 1.

[0076] like Figure 8 and Figure 9 As shown, in some embodiments, the air blowing assembly 14 includes a blocking portion 141, a body portion 142, and an air supply portion 144. The side of the body portion 142 closest to the positioning assembly 11 is fitted onto the blocking portion 141 to form an air blowing slit 143 facing the positioning assembly 11 between the body portion 142 and the blocking portion 141; the air supply portion 144 is connected to the air blowing slit 143.

[0077] By fitting the side of the main body 142 close to the positioning component 11 around the outer periphery of the blocking part 141, an air-blowing slit 143 is formed facing the positioning component 11. When the air supply part 144 starts supplying air, the gas can be blown out through the air-blowing slit 143, which can increase the flow rate of the blown gas, thereby improving the dust removal effect of the battery welding device 1 and improving the welding quality of the battery 3.

[0078] like Figures 1 to 5 As shown, in some embodiments, the battery welding apparatus 1 further includes a smoke blocking member 15 disposed between the air blowing assembly 14 and the dust suction assembly 13.

[0079] In some embodiments, the fume blocking member 15 may be a closed hollow structure, connecting the air blowing assembly 14 and the dust suction assembly 13 through an extended hollow channel. In other embodiments, the fume blocking member 15 may also be a semi-closed thin-walled structure such as a U-shaped structure, using the thin wall to block fume impurities generated during the welding process.

[0080] By placing the fume blocking component 15 between the air blowing assembly 14 and the dust suction assembly 13, a fully enclosed or semi-enclosed airflow channel 151 is formed between the air blowing assembly 14 and the dust suction assembly 13. This can prevent the splashing and diffusion of fumes and impurities during the welding process from affecting the dust removal effect, and can also guide the gas blown out by the air blowing assembly 14, enhance the concentration of gas flow, and further improve the dust removal effect of the battery welding device 1.

[0081] like Figure 5 and Figure 6 As shown, in some embodiments, the positioning component 11 includes a mounting member 111, a positioning member 112, a first pushing member 113, and a second pushing member 114. The positioning member 112 is disposed on the mounting member 111; the first pushing member 113 and the second pushing member 114 are respectively disposed on both sides of the positioning member 112; the first pushing member 113 and / or the second pushing member 114 are movably disposed on the mounting member 111.

[0082] The positioning component 112 can be a clamping mechanism such as a gripper or a positioning mechanism such as a positioning hole. By setting the positioning component 112, the battery 3 can be positioned in the battery welding device 1, ensuring the accuracy and quality of subsequent battery 3 welding.

[0083] The first pusher 113 and the second pusher 114 are respectively disposed on both sides of the positioning member 112, and the first pusher 113 and / or the second pusher 114 are movably disposed on the mounting member 111. In this way, the first pusher 113 and / or the second pusher 114 can be driven to bring them closer together and abut against the cap 31 and the housing 32, ensuring precise alignment and tight pressing between the two, thereby ensuring good contact of the welding interface and improving the welding quality of the cap 31 and the housing 32.

[0084] The first pushing member 113 and / or the second pushing member 114 are movably disposed on the mounting member 111. That is, in some embodiments, one of the first pushing member 113 and the second pushing member 114 is movably disposed on the mounting member 111; while in other embodiments, both the first pushing member 113 and the second pushing member 114 are movably disposed on the mounting member 111. The movable arrangement between the first pushing member 113 and the mounting member 111 can be achieved by a guide rail slider mechanism or a lead screw mechanism, and this application embodiment does not limit this. Similarly, the movable arrangement between the second pushing member 114 and the mounting member 111 can also be achieved by a guide rail slider mechanism or a lead screw mechanism, and this application embodiment also does not limit this.

[0085] Specifically, the air blowing assembly 14, the smoke blocking component 15, the dust suction assembly 13, and the laser emitter 121 are arranged sequentially along the first direction X, so that the laser emitted by the laser emitter 121 passes through the dust suction assembly 13 along the first direction X and acts on the battery 3. The mounting component 111 extends along the second direction Y, and the first pushing component 113 and / or the second pushing component 114 are movably arranged along the second direction Y, pushing the cap 31 and the housing 32 closer together along the second direction Y to facilitate subsequent welding of the cap 31 and the housing 31.

[0086] like Figure 5 and Figure 6As shown, in some embodiments, the first pusher 113 includes a rotating part 1131, a mounting hole 1132, and an ejector part 1133. The rotating part 1131 is rotatably disposed on the mounting part 111; the mounting hole 1132 is disposed through the rotating part 1131; and the ejector part 1133 is movably disposed within the mounting hole 1132.

[0087] The rotating part 1131 is rotatably disposed on the mounting part 111. During the welding process, the rotatable rotating part 1131 abuts against the battery 3. When the rotating part 1131 rotates relative to the mounting part 111, it can drive the battery 3 to rotate, so that the laser emitted by the laser emitter 121 can perform 360° circumferential welding along the circumference of the battery 3, thereby forming a complete and uniform circumferential weld on the battery 3, ensuring the sealing and firmness of the welding of the cap 31 and the shell 32.

[0088] A mounting hole 1132 is provided through the rotating part 1131, and an ejector part 1133 is movably disposed within the mounting hole 1132, allowing the ejector part 1133 to move relative to the rotating part 1131. In this way, during welding, the ejector part 1133 can retract into the mounting hole 1132, ensuring effective contact between the rotating part 1131 and the battery 3, and ensuring effective contact between the cap 31 and the housing 32 while the battery 3 rotates. After welding is completed, the ejector part 1133 can extend out of the mounting hole 1132, thereby detaching the battery 3 from the rotating part 1131, facilitating subsequent unloading of the battery 3.

[0089] It should be noted that the mounting hole 1132 can be a regular shape such as a circle or a square, or it can be an irregular shape composed of straight lines and / or curves. This application embodiment does not limit this. Similarly, the cross-sectional shape of the ejector part 1133 can also be a regular shape such as a circle or a square, or an irregular shape composed of straight lines and / or curves. This application embodiment does not limit this either, as long as the shape of the mounting hole 1132 is consistent with the cross-sectional shape of the ejector part 1133, and the ejector part 1133 can be inserted into the mounting hole 1131 and can move in the mounting hole 1132.

[0090] In some embodiments, the ejector portion 1133 has a pusher near the end of the battery 3, and the rotating portion 1131 has a receiving portion near the end of the battery 3, in which the pusher can be received. The cross-sectional area of ​​the pushing portion is larger than that of the ejector portion, thus reducing the pressure on the battery 3 during the pushing process and protecting the surface quality of the battery 3. In some embodiments, the pusher can also be made of a soft material, which can further improve the surface quality of the battery 3. In addition, by providing the receiving portion, the pusher can be housed therein, ensuring effective contact between the rotating portion 1131 and the battery 3 during the welding process.

[0091] like Figure 5 and Figure 6 As shown, in some embodiments, the second pusher 114 includes a push mounting portion 1141 and a driven portion 1142. The push mounting portion 1141 is disposed on the mounting member 111; the driven portion 1142 is rotatably disposed on the push mounting portion 1141, and the driven portion 1142 is correspondingly disposed with the rotating portion 1131.

[0092] The push mounting part 1141 is disposed on the mounting member 111. Specifically, the push mounting part 1141 can be fixedly disposed on the mounting member 111. The battery 3 is abutted between the first push member 113 and the second push member 114 by the movement of the first push member 113. In other embodiments, the push mounting part 1141 can be movably disposed on the mounting member 111 by a guide rail slider mechanism or a screw mechanism. In this way, the second push member 114 can move closer to or away from the first push member 113, thereby realizing the abutment and release of the battery 3.

[0093] The driven part 1142 is rotatably disposed on the push mounting part 1141. In this way, when the rotating part 1131 drives the battery 3 to rotate, the driven part 1142 can also rotate synchronously, so that the driven part 1142 and the battery 3 can remain relatively stationary, preventing them from rubbing against each other and damaging the surface of the battery 3.

[0094] The driven part 1142 and the rotating part 1131 are respectively arranged, that is, the projections of the rotating part 1131 and the driven part 1142 on the second direction Y along the axial direction of the battery 3 coincide with each other, so that the clamping force applied to the battery 3 by the first pusher 113 and the second pusher 114 can coincide with the axial direction of the battery 3 on the battery welding device 1, thereby preventing the battery 3 from being deflected and affecting the welding accuracy.

[0095] like Figure 5 and Figure 6 As shown, in some embodiments, the positioning member 112 includes a positioning part 1121 and a magnetic part 1122 disposed on the positioning part 1121.

[0096] The magnetic part 1122 can be a permanent magnet or an electromagnet, and the embodiments of this application do not limit it.

[0097] By placing the magnetic part 1122 in the positioning part 1121, the battery 3 can be attracted and fixed by magnetic force, ensuring that the battery 3 is stably positioned in the battery welding device 1 and ensuring the welding accuracy of the battery 3.

[0098] like Figure 3 and Figure 4As shown, in some embodiments, the positioning member 112 includes a first roller 1123 and a second roller (not shown) spaced apart, so as to form a positioning portion 1121 between the first roller 1123 and the second roller.

[0099] The first and second rollers refer to cylindrical components. The first and second rollers can be fixed or can be rotated around their own axes. This application does not limit this.

[0100] By setting the first roller 1123 and the second roller at an interval to form the positioning part 1121, the cylindrical battery 3 is positioned on the positioning part 1121. In this way, the cylindrical battery 3 is in line contact with the first roller 1123 and the second roller, which can improve the stability of the battery 3 positioning.

[0101] In some embodiments, the first wheel 1123 and the second wheel are spaced apart along a third direction Z, which is perpendicular to the first direction X and the second direction Y.

[0102] like Figure 1 and Figure 10 As shown, in some embodiments, the welding assembly 12 further includes a welding mount 122, on which the laser emitter 121 is movably disposed.

[0103] The movable connection between the laser emitter 121 and the welding mounting part 122 can be achieved by a guide rail slider mechanism or a lead screw mechanism; this application embodiment does not limit this.

[0104] By movably mounting the laser emitter 121 on the welding mounting component 122, the position of the laser emitter 121 can be adjusted during the welding process, thereby ensuring that the laser emitter 121 and the positioning component 11 are at the same height, thus ensuring the welding accuracy of the battery 3.

[0105] In other embodiments, the position of the laser emitter 121 in the horizontal direction can also be adjusted to further improve the welding accuracy of the battery welding device 1.

[0106] like Figure 10 As shown, in some embodiments, the battery welding apparatus 1 further includes a cleaning component 16, which is disposed downstream of the welding component 12, and the cleaning component 16 is disposed corresponding to the positioning component 11 to clean the welding part of the battery 3.

[0107] The cleaning component 16 refers to a part used to clean the weld seam after the battery 3 has been welded. Specifically, in some embodiments, the cleaning component 16 can be a brush component, which brushes away impurities such as welding slag from the weld seam to prevent welding slag from falling and contaminating the battery production environment, or even scratching or puncturing the battery 3, thereby improving the production quality of the battery 3. In other embodiments, the cleaning component 16 can also be a laser component, which removes welding slag around the weld seam of the battery 3 by emitting a laser.

[0108] like Figure 10 As shown, this application also provides a battery production apparatus, including a turntable 2 and a battery welding device 1. The turntable 2 is rotatable along its own axis; the battery welding device 1 includes at least one positioning component 11 disposed on the outer periphery of the turntable 2.

[0109] The battery welding device 1 includes at least one positioning component 11. That is, in some embodiments, the battery welding device 1 includes multiple positioning components 11. The multiple positioning components 11 are arranged on the outer periphery of the turntable 2. By rotating the turntable 2, different positioning components 11 can be sequentially transported to the welding position corresponding to the welding component 12, thereby completing the welding process of the battery 3 in sequence and improving the production efficiency of the battery 3.

[0110] For ease of description, the following explanation uses the welding process of the cap 31 and the casing 32 of battery 3 as an example. That is, the battery welding device 1 of this application can also be used for welding other components on battery 3. Specifically, as... Figures 1 to 10 As shown, during the feeding process, the battery 3 is fed into the positioning assembly 11 and fixed in the positioning part 1121 by the attraction of the magnetic part 1122; subsequently, the first pusher 113 and the second pusher 114 approach each other along the second direction Y and abut against each other.

[0111] Next, the suction unit 132 covers one side of the battery 3, and the rotating unit 1131 rotates around its own axis, thereby driving the battery 3 to rotate around its own axis. At the same time, the laser emitter 121 and the air blowing assembly 14 are activated. While the laser emitter 121 emits a laser to weld the battery 3, the air blowing assembly 14 and the suction unit 13 extract the smoke and dust generated during the welding process. The battery 3 rotates around its own axis, forming an annular weld on its outer periphery, thus completing the welding of the cap 31 and the shell 32 of the battery 3.

[0112] After the welding of the battery 3 is completed, the turntable 2 rotates around its own axis, rotating the positioning component 11 and the battery 3 on it out of the welding station, and rotating the next positioning component 11 and the battery 3 to be welded on it into the welding station corresponding to the welding component 12. At the same time, the ejector part 1133 extends out of the mounting hole 1132 along the second direction Y, and unloads the welded battery 3 from the rotating part 1131 and from the battery welding device 1.

[0113] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0114] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
