Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.
[0027] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.
[0028] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the ultrasonic welding dust removal device 100 of some embodiments of this application includes a dust removal hood 110 and at least two negative pressure pipelines 120. The dust removal hood 110 is disposed in the welding area 230 (see reference). Figure 6 On one side of the dust hood 110, the dust hood 110 is provided with an opening 113 for the welding head to pass through; each negative pressure pipeline 120 includes a first end 121 and a second end 122, the first end 121 of each negative pressure pipeline 120 is connected to the dust hood 110, and the second end 122 of each negative pressure pipeline 120 leads to an external negative pressure supply device.
[0029] The welding area 230 refers to the welding point where the electrode tab and the adapter plate of the battery cell are welded. The welding head is the upper welding head 220. The dust hood 110 is located on the upper side of the welding area 230. The upper welding head 220 extends into the welding area 230 from the upper side of the dust hood 110 and welds the electrode tab and the adapter plate together using ultrasonic technology. The negative pressure supply device can be a vacuum fan or other negative pressure source. The number of negative pressure pipes 120 can be two, three, four, etc. The dust hood 110 has a dust removal channel 114 inside, and the first end 121 of the negative pressure pipe 120 is connected to the dust removal channel 114. Alternatively, the side of the dust hood 110 near the welding area 230 can be a negative pressure space, and the negative pressure pipe 120 extends into the side of the dust hood 110 near the welding area 230.
[0030] The ultrasonic welding dust removal device 100 of this application embodiment has a dust removal hood 110 and is connected to at least two negative pressure pipes 120. The dust removal hood 110 forms a small isolation space in the welding area 230. The multiple negative pressure pipes 120 work together to perform negative pressure suction on the welding area 230, which not only prevents the dust generated during the welding process from spreading and splashing, but also ensures that the wind speed is roughly uniform, so as to suck the dust out of the welding area 230 from all directions, which has a good dust removal effect and thus improves the welding quality.
[0031] like Figure 2 and Figure 5 As shown, in some embodiments of this application, two negative pressure pipes 120 are provided, with the opening 113 being rectangular. The first end 121 of one negative pressure pipe 120 is located on the long side 1131 of the opening 113, and the first end 121 of the other negative pressure pipe 120 is located on the short side 1132 of the opening 113.
[0032] An opening 113 extends through the dust collector hood 110 along the Z-direction. The opening 113 includes two long sides 1131 arranged opposite each other along the X-direction and two short sides 1132 arranged opposite each other along the Y-direction. Two negative pressure pipes 120 are designated as a first negative pressure pipe and a second negative pressure pipe. The first end 121 of the first negative pressure pipe is located on one side of the opening 113 along the X-direction, and the first end 121 of the second negative pressure pipe is located on one side of the opening 113 along the Y-direction. The first end 121 of the first negative pressure pipe can be located on the long side 1131 of the opening 113 in the Y-direction; the first end 121 of the second negative pressure pipe can be located offset from the short side 1132 of the opening 113 in the X-direction, or it can be centrally located on the short side 1132.
[0033] It is understandable that a large amount of dust is generated during the welding process of the electrode and the adapter piece. The dust is concentrated in the welding area 230. If the dust accumulates in the welding area 230, it will seriously reduce the welding quality. If the dust splashes out from the opening 113, it will also pollute the workshop environment. Therefore, uneven ventilation will also lead to dust accumulation, thereby reducing the welding quality.
[0034] With this configuration, two negative pressure sections can be set up near the opening 113 to vacuum and remove dust from both the long side 1131 and the short side 1132 of the opening 113, so that the wind speed in the welding area 230 is roughly uniform and dust is removed from all directions.
[0035] In other embodiments, the opening 113 may also be circular, with multiple negative pressure pipes 120 spaced around the opening 113.
[0036] like Figure 5 As shown, in some embodiments of this application, the distance between the first end 121 of the negative pressure pipeline 120 disposed on the long side 1131 of the opening 113 and the opening 113 is L1, and the distance between the first end 121 of the negative pressure pipeline 120 disposed on the short side 1132 of the opening 113 and the opening 113 is L2, satisfying: L1 < L2.
[0037] The distance between the first end 121 and the opening 113 refers to the minimum distance between the centerline of the first end 121 and the edge of the opening 113. Specifically, the distance between the first end 121 of the negative pressure pipe 120 disposed on the long side 1131 of the opening 113 and the opening 113 refers to the distance L1 between the centerline of the first end 121 and the near long side 1131 in the X direction; the distance between the first end 121 of the negative pressure pipe 120 disposed on the short side 1132 of the opening 113 and the opening 113 refers to the distance L2 between the centerline of the first end 121 and the near short side 1132 in the Y direction.
[0038] As a preferred example, in the X direction, the centerlines of the first ends 121 of the two negative pressure pipes 120 are aligned to facilitate wind speed calculation.
[0039] This configuration allows for adjustment of the wind speed on the long side 1131 and the short side 1132, making the wind speed on the long side 1131 and the short side 1132 roughly uniform, thereby removing dust from all directions.
[0040] In other embodiments, the opening 113 can be circular or square, and the distance between each negative pressure pipe 120 and the edge of the opening 113 is equal.
[0041] like Figure 2 , Figure 4 and Figure 6As shown, in some embodiments of this application, the dust removal hood 110 has a dust removal channel 114 inside, the first end 121 of each negative pressure pipe 120 is connected to the dust removal channel 114, and the periphery of the opening 113 is provided with a negative pressure port 1133 connected to the dust removal channel 114.
[0042] The periphery of opening 113 refers to the periphery surrounding the opening direction (i.e., the Z direction) of opening 113. For example, negative pressure port 1133 can be an annular opening that extends continuously around the periphery of opening 113; or, for another example, multiple negative pressure ports 1133 can be provided, with multiple negative pressure ports 1133 spaced apart on the periphery of opening 113.
[0043] With this configuration, a small isolation space can be formed near the welding area 230, and the dust generated during the welding process of the battery cell's tab and the adapter piece is sucked into the dust removal channel 114 through the negative pressure port 1133.
[0044] In other embodiments, the dust hood 110 may also be installed over the welding area 230, directly drawing dust from the welding area 230 into the negative pressure pipe 120.
[0045] In some embodiments of this application, the dust hood 110 includes an upper hood 111 and a lower hood 112, with a dust removal channel 114 formed between the upper hood 111 and the lower hood 112.
[0046] The upper cover 111 and the lower cover 112 are spaced apart along the Z direction. The upper cover 111 and the lower cover 112 are fixedly connected and together enclose a dust removal channel 114. The upper cover 111 is provided with a pipe through hole. The first end 121 of each negative pressure pipe 120 passes through the corresponding pipe through hole and communicates with the dust removal channel 114.
[0047] This configuration allows the negative pressure port 1133 to be located close to the dust source, while also isolating the dust to a greater extent, reducing the range of dust diffusion, and improving the dust removal effect.
[0048] In some embodiments of this application, a dust removal gap is formed between the peripheral edge of the opening 113 and the welding head.
[0049] There is a gap between the plane containing the negative pressure port 1133 and the outer peripheral surface of the welding head. After the welding head is inserted into the opening 113, there is a gap between the long side 1131 of the opening 113 and the outer peripheral surface of the welding head in the X direction. For example, the gap W between the peripheral side of the opening 113 and the upper welding head 220 is the dust removal gap; the dust removal gap can be a constant value or it can vary at different locations in the circumference of the opening 113.
[0050] With this configuration, a negative pressure environment can be formed on the side of the dust hood 110 away from the welding area 230. This facilitates the up-and-down movement of the welding head and reduces the possibility of dust overflowing from the gap between the welding head and the opening 113, thereby reducing the range of dust diffusion and improving dust removal efficiency.
[0051] like Figure 2 and Figure 4 As shown, in some embodiments of this application, each negative pressure pipeline 120 has a connecting piece 130 at its first end 121, and the connecting piece 130 is detachably connected to the dust cover 110.
[0052] The connecting piece 130 is fixedly connected to the first end 121. The connecting piece 130 and the upper cover 111 are stacked and assembled into one piece by threaded parts and bolts. The upper cover 111 is provided with a pipe through hole corresponding to the first end 121. The first end 121 is inserted into the pipe through hole to exhaust air from the dust removal channel 114.
[0053] This configuration allows the negative pressure line 120 to be detachably connected to the dust cover 110.
[0054] In other embodiments, the negative pressure pipeline 120 may also be integrally formed with the dust cover 110, or snap-fit connected to the dust cover 110, etc.
[0055] like Figure 1 As shown, in some embodiments of this application, the negative pressure pipeline 120 extends obliquely from the first end 121 to the second end 122 in a direction away from the opening 113.
[0056] Specifically, the first negative pressure pipeline is connected to the dust removal channel 114 along the X direction, and the second negative pressure pipeline is connected to the dust removal channel 114 along the Z direction.
[0057] This configuration allows the negative pressure airflow to carry dust away from the welding area 230, thus removing the dust from the welding area 230.
[0058] In other embodiments, the negative pressure line 120 may also extend along the Z direction.
[0059] like Figure 1 As shown, in some embodiments of this application, the ultrasonic welding dust removal device 100 further includes two battery cell fixing structures 140, which are spaced apart, and a dust removal hood 110 is disposed between the two battery cell fixing structures 140, and the dust removal hood 110 is fixedly connected to the battery cell fixing structures 140.
[0060] The cell fixing structure 140 fixes the cell to the welding socket 210 and presses the electrode tab and the adapter plate together to facilitate the next welding process.
[0061] By integrating the battery cell fixing structure 140 with the dust cover 110 through this configuration, the functions of fixing the battery cell and welding dust removal can be met, simplifying the number of components required for the welding process.
[0062] like Figure 3 As shown, in some embodiments of this application, the ultrasonic welding dust removal device 100 further includes a connecting bracket 150, which is provided with a fixing part 151 for fixing the negative pressure pipeline 120.
[0063] The connecting bracket 150 is provided with two fixing parts 151, which correspond one-to-one with the negative pressure pipeline 120; the connecting bracket 150 is also provided with a connecting part 152, which is fixedly connected to the dust cover 110 or the battery cell fixing structure 140 through the connecting part 152.
[0064] Some embodiments of the ultrasonic welding apparatus 200 of this application include an ultrasonic welding dust removal device 100.
[0065] like Figure 6 As shown, the ultrasonic welding equipment 200 includes a welding base 210, an upper welding head 220, and an ultrasonic welding dust removal device 100. The upper side of the welding base 210 is the welding area 230, and the dust removal hood 110 is disposed on the upper side of the welding area 230. The upper welding head 220 passes through the opening 113 to perform welding. The dust removal hood 110 can be installed on the upper side of the welding base 210 in a lifting mechanism, or the welding base 210 can be raised to fix the battery cell.
[0066] The welding base 210 includes a lower welding head 211 and a lower dust cover 212. The lower dust cover 212 has an opening through which the lower welding head 211 passes. The lower dust cover 212 can be the ultrasonic welding dust removal device 100 of the present application embodiment, or it can be other types of dust removal devices.
[0067] Due to the characteristics of the ultrasonic welding dust removal device 100 in this application embodiment, the ultrasonic welding equipment 200 in this application embodiment also has a good dust removal effect, thereby improving the welding quality.
[0068] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.
[0069] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
