[0034] DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the schemes in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0036] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] It should also be noted that when an element is referred to as being "fixed on" or "disposed on" another element, it may be directly on the other element or there may be an intermediate element. When an element is referred to as being "connected to" another element, it may be directly connected to the other element or there may be an intermediate element.

[0038] In addition, the descriptions of "first," "second," etc. in this utility model are for descriptive purposes only and should not be understood as indicating or implying their relative importance or implicitly indicating the number of the technical features indicated. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of such features. In addition, the technical solutions between the various embodiments can be combined with each other, but this must be based on the fact that they can be implemented by ordinary technicians in this field. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0039] Please refer to Figures 1 to 3The present invention provides a battery-cell dust collection device comprising a base 1, a dust collection body 2, an airflow generating assembly, and a negative pressure assembly. The dust collection body 2 is disposed on the base 1 and is provided with a dust collection channel 21 and an air blowing channel 22, which are separated from each other. The dust collection channel 21 has a dust collection inlet 211 and a dust collection outlet 212, while the air blowing channel 22 has an air blowing inlet 221 and at least one air blowing outlet 222. The dust collection inlet 211 and the at least one air blowing outlet 222 are spaced apart and disposed on one side of the dust collection body 2.

[0040] In this embodiment, the base 1 serves as a supporting platform for the dust collecting body 2 , ensuring that the dust collecting body 2 can be firmly installed and work in conjunction with the airflow generating component and the negative pressure component to collect dust from the battery cells.

[0041] In this embodiment, the connection between the vacuum cleaner body and the base can be fixed or movable. A fixed connection between the vacuum cleaner body and the base, such as a screw connection, provides a stable structure and is suitable for situations requiring stable vacuuming. A movable connection between the vacuum cleaner body and the base, such as a sliding connection, allows the vacuum cleaner body to move freely to a certain extent, adapting to different vacuuming needs, thereby improving vacuuming efficiency and convenience.

[0042] The airflow generating assembly is in communication with the air blowing inlet, and is used to input airflow into the air blowing channel and blow air toward the notch of the battery cell through at least one air blowing outlet;

[0043] The negative pressure component is communicated with the dust suction outlet, and is used for sucking away the gas at the notch of the battery cell and sucking away foreign matter at the notch of the battery cell through the dust suction inlet.

[0044] When it is necessary to vacuum the notch of the battery cell, the vacuum inlet is aligned with a part of the battery cell notch, and the air outlet is aligned with another part of the battery cell notch. The negative pressure component sucks away the gas at the battery cell notch through the vacuum inlet to form a negative pressure at the battery cell notch, thereby sucking away foreign matter at the battery cell notch through the vacuum inlet 211. At the same time, the airflow generating component inputs airflow into the air blowing channel 22 and blows up foreign matter on the battery cell notch edge through the air blowing outlet, so that foreign matter on the battery cell notch edge can be sucked in by the vacuum inlet, thereby achieving the removal of foreign matter in the battery cell notch and the notch edge. The battery cell vacuuming device of the present invention can more effectively clean foreign matter adsorbed on the battery cell by simultaneously driving the airflow generating component and the negative pressure component to work, thereby improving the vacuuming efficiency and vacuuming effect.

[0045] It should be noted that the airflow generating component can be an air pump, an air compressor, etc. In theory, as long as it can deliver gas to the blowing channel 22, the present invention does not impose any limitation on this.

[0046] In some embodiments, the negative pressure component can be a vacuum pump, a Roots blower, a centrifugal blower, or the like. For example, a vacuum pump can be used as the negative pressure component, as it has a simple and compact structure. Of course, the above is merely exemplary, and the specific type of negative pressure component will depend on actual needs, and the present invention is not intended to limit this.

[0047] In this embodiment, the dust collection channel 21 and the air blowing channel 22 are both located within the dust collection body 2 and are separated from each other. This design ensures the independence and efficiency of the dust collection and air blowing functions. The dust collection channel is specifically used to collect foreign matter from the surface of the battery cell notch, while the air blowing channel is used to blow away foreign matter from the battery cell notch surface. Because these two channels are separated, they can operate independently without interfering with each other, thereby improving the overall performance and ease of use of the battery cell dust collection device.

[0048] In some embodiments, the dust collection inlet 211 and at least one air outlet 222 are spaced apart on one side of the dust collection body 2. This compact structure facilitates the timely removal of blown-up foreign matter, improving dust collection efficiency and completeness. This design helps improve dust collection efficiency. By spacing the dust collection inlet and air outlet, foreign matter at the battery cell slots can be effectively attracted and collected while preventing it from being blown away, thereby improving dust collection efficiency.

[0049] In one possible embodiment, at least two air outlets 222 are provided, and the at least two air outlets 222 are spaced apart along the circumference of the dust suction inlet 211. For example, the number of air outlets 222 may be two, three, or more. Exemplarily, the air blowing channel 22 includes four air outlets 222, which are spaced apart along the circumference of the dust suction inlet 211. This can blow away foreign matter from all four directions of the battery cell slot, improving suction efficiency.

[0050] Of course, in another possible embodiment, the dust suction inlet 211 and the air blowing outlet 222 may also be linearly arranged and spaced apart on one side of the dust suction body 2 , and the present invention does not limit this.

[0051] Please refer to Figure 3 In order to match the dust collection body 2 with the battery cell slot, in some embodiments, the end of the dust collection body 2 away from the base 1 is recessed inward to form a cavity 23, and the dust collection inlet 211 and at least one blowing outlet 222 are spaced apart and arranged on the bottom wall of the cavity 23.

[0052] In this embodiment, during vacuuming, the recessed cavity 23 covers the cell notch, facilitating the negative pressure component to create negative pressure at the cell notch and the airflow generating component to blow away foreign matter along the cell notch toward the vacuum inlet. Furthermore, when the recessed cavity 23 covers the cell notch, it also prevents foreign matter blown away from the cell notch from dispersing, facilitating centralized vacuuming.

[0053] There are many options for the shape of the cavity 23. Figure 2 The concave cavity 23 can be set as an annular concave cavity 23, which can match the shape of the battery cell to cover the battery cell notch. Of course, the concave cavity 23 can also be set as a rectangular concave cavity 23, depending on actual needs, and the present invention is not limited here.

[0054] Please refer to Figure 2 and Figure 4 In this embodiment, the dust collector body 2 includes a rod body 25 and a dust collector head 24. One end of the rod body 25 is connected to the base 1, and the other end of the rod body 25 is connected to the dust collector head 24. The dust collection inlet 211 and at least one blowing outlet 222 are spaced apart and arranged at the end of the dust collector head 24 away from the rod body 25.

[0055] The rod 25 serves as the intermediate structure connecting the vacuum assembly and the cleaner head 24, and its shape can be selected in a variety of different ways. Exemplarily, the rod 25 is configured as a hollow cylindrical structure. By connecting to the cleaner head 24 and cooperating with the vacuum assembly, foreign matter is sucked up from the suction inlet 211 and flows through the channel within the rod 25 to the vacuum assembly, where it is collected. Of course, the rod 25 can also be configured in other shapes, such as an elliptical or polygonal radial cross-section, and this is not a limitation of the present invention.

[0056] The dust collecting head 24 is a part that directly covers the battery cell slot to blow and collect dust. A dust collection inlet 211 and at least one air blowing outlet 222 are provided at one end of the dust collecting head 24 away from the rod body 25 , and the two are spaced apart.

[0057] Please refer to Figure 3 and Figure 5 The rod body 25 provided in this embodiment is provided with a first hole section 251 and a second hole section 252. The first hole section 251 and the second hole section 252 are connected in sequence along the direction in which the rod body 25 is inserted into the dust collector 24. The end of the first hole section 251 away from the second hole section 252 has a dust suction outlet 212; the dust collector 24 is provided with a third hole section 241 and a fourth hole section 242. The third hole section 241 and the fourth hole section 242 are coaxially separated and arranged. The third hole section 241 has an air blowing inlet 221 and an air blowing outlet 222, and the fourth hole section 242 has a dust suction inlet 211. When the dust collector 24 is connected to the rod body 25, the first hole section 251 is connected to the fourth hole section 242 to form a dust suction channel 21, and the second hole section 252 is connected to the third hole section 241 to form a blowing channel 22.

[0058] By designing the interior of the rod body 25 and the dust collector head 24 provided in this embodiment into a structure in which multiple hole segments are connected, when the rod body 25 and the dust collector head 24 are installed, the hole segments inside the two can cooperate with each other to form a blowing channel 22 and a dust collection channel 21 that are separated from each other, so that the battery core dust collection device can blow dust and collect dust at the same time, thereby improving the dust collection efficiency and dust collection effect.

[0059] Please continue to refer to Figure 3 and Figure 5 , wherein a first step 253 is formed at the connection between the first hole section 251 and the second hole section 252; the third hole section 241 includes a first sub-hole section 2411 and a second sub-hole section 2412, the first sub-hole section 2411 is connected to the second sub-hole section 2412 and a second step 2413 is formed at the connection; the end of the rod body 25 away from the base 1 is inserted into the first sub-hole section 2411 and abuts on the second step 2413, and the cavity top wall of the fourth hole section 242 is inserted into the second hole section 252 and abuts on the first step 253 to separate the dust suction channel 21 and the air blowing channel 22.

[0060] When the cleaner head 24 and the rod body 25 are installed together, the second hole section 252 of the rod body 25 fits neatly into the first sub-hole section 2411 of the cleaner head 24. The end of the second hole section 252 abuts the second step 2413, and the end of the fourth hole section 242 abuts the first step 253. This facilitates confirmation that the cleaner head 24 and the rod body 25 are properly plugged in, and prevents the blowing channel 22 and the dust suction channel 21 from being separated when the cleaner head 24 and the rod body 25 are not properly plugged in, thereby affecting the dust blowing and dust suction effects. At the same time, after the fourth hole section 242 abuts the first step 253, the first hole section 251 and the fourth hole section 242 are connected to form the dust suction channel 21, and the second hole section 252 fits into the first sub-hole section 2411 to form the blowing channel 22. Thus, the blowing channel 22 is separated from the dust collection channel 21 by the fourth hole section 242 and the first hole section 251, preventing airflow interference between the blowing channel 22 and the dust collection channel 21, ensuring the independence and effectiveness of the dust collection and blowing functions. At the same time, the dust collection channel 21 can be connected to the rod body 25, and the negative pressure component can generate suction at the dust collection inlet 211 to remove foreign matter. The foreign matter passes through the fourth hole section 242 of the dust collector head, the first hole section 251 of the rod body 25, and finally is sucked away from the dust collection outlet 212, forming a complete dust collection path.

[0061] Please refer to Figure 6In order to input air flow into the blowing channel 22, the blowing inlet 221 includes at least one first through hole 2211 provided on the rod body 25 and at least one second through hole 2212 provided on the dust collector head 24. At least one first through hole 2211 is connected to the second hole segment 252, and at least one second through hole 2212 is connected to the first sub-hole segment 2411. At least one first through hole 2211 and at least one second through hole 2212 are connected in a one-to-one correspondence.

[0062] The airflow generating assembly inputs airflow to the blowing channel 22 through the connected first through hole 2211 and the second through hole 2212 . The airflow is blown out from the blowing outlet 222 , blowing up foreign matter so that the dust collection channel 21 can suck it in.

[0063] Please continue to refer to Figure 6 In order to firmly connect the vacuum cleaner head 24 and the rod body 25, at least one first mounting hole 254 is provided on the rod body 25, and at least one first mounting hole 254 is communicated with the second hole section 252. At least one second mounting hole 243 is provided on the vacuum cleaner head 24, and at least one second mounting hole 243 is communicated with the first sub-hole section 2411. At least one first mounting hole 254 is communicated with at least one second mounting hole 243 in a one-to-one correspondence. Screws are sequentially passed through the first mounting hole 254 and the second mounting hole 243 to connect the rod body 25 and the vacuum cleaner head 24 together. The installation is firm and easy to disassemble.

[0064] In some embodiments, the electric core dust collection device provided in this embodiment further includes a driving mechanism, which is connected to the dust collection body 2 and is used to drive the dust collection body 2 to move relative to the base 1.

[0065] When vacuuming the battery cell, the drive mechanism drives the rod 25 relative to the base 1 to move closer to the battery cell notch, allowing the cavity 23 of the vacuum head 24 to cover the battery cell notch, facilitating the air passage 22 to blow up foreign matter and the vacuum passage 21 to suck it away. After the foreign matter is removed, the drive mechanism drives the rod 25 away from the battery cell, thereby driving the cavity 23 of the vacuum head 24 away from the battery cell notch, allowing the battery cell to be transferred to the subsequent process.

[0066] For example, the driving mechanism can be a cylinder, the output end of which is in transmission connection with the rod body 25, and the piston movement of the cylinder drives the rod body 25 to slide axially relative to the base 1, thereby driving the dust collector body 2 to move relative to the base 1. Of course, the driving mechanism can also be a motor, etc., as long as it can theoretically drive the rod body 25 to move relative to the base 1, and the present invention is not limited thereto.

[0067] In some embodiments, the battery core dust collection device further includes a connecting sleeve 3 , which is connected to the base 1 , the dust collection body 2 is axially penetrated by the connecting sleeve 3 , and the driving mechanism drives the dust collection body 2 to move relative to the connecting sleeve 3 .

[0068] In this embodiment, the axial cross-section of the connecting sleeve 3 is T-shaped, and includes a connecting sleeve body 31 and a connecting sleeve flange 32 .

[0069] For example, please refer to Figure 7 A plurality of third mounting holes 321 are provided on the connecting sleeve flange 32, and correspondingly, an equal number of fourth mounting holes 11 are provided on the base 1. The plurality of third mounting holes 321 and the plurality of fourth mounting holes 11 are connected and arranged in a one-to-one correspondence. The base 1 and the connecting sleeve 3 are connected together by screws passing through the third mounting holes 321 and the fourth mounting holes 11 in sequence. The installation is stable and easy to disassemble.

[0070] Please refer to Figure 1 and Figure 7 The connecting sleeve 3 is a hollow structure, and the rod body 25 of the dust collecting body 2 is passed through the connecting sleeve 3 and connected to the driving mechanism. When the battery cell dust collecting device is started, the driving mechanism drives the rod body 25 to slide along the connecting sleeve 3. When vacuuming the battery cell, the driving mechanism drives the rod body 25 to slide relative to the connecting sleeve 3 to drive the dust collecting head 24 close to the battery cell, so that the concave cavity 23 can cover the battery cell notch, which is convenient for blowing and vacuuming. After the battery cell is vacuumed, the driving mechanism drives the rod body 25 away from the battery cell, and the battery cell can be transferred to the subsequent process. At the same time, the battery cell to be vacuumed can also be transferred to the vacuuming station to improve efficiency.

[0071] Please continue to refer to Figure 1 and Figure 7 The battery core dust collection device also includes an elastic buffer 4, which is connected to the dust collection body 2 and is located between the end of the dust collection body 2 and the connecting sleeve 3, and is used to provide elastic restoring force when the dust collection body 2 moves relative to the connecting sleeve 3.

[0072] When the battery cell vacuuming device is activated to vacuum the battery cell slot, the elastic buffer 4 can act as a buffer between the vacuuming body 2 and the battery cell, preventing the vacuuming body 2 from moving too much under the drive mechanism and directly physically contacting or impacting the battery cell, thereby damaging the battery cell. At the same time, after vacuuming is completed, the elastic buffer 4 has an elastic force, which can assist the vacuuming body 2 in returning to its original position when the drive mechanism controls the vacuuming body 2 to move away from the battery cell.

[0073] Please refer to Figure 1 The elastic buffer member 4 provided in this embodiment is a spring, which is sleeved outside the dust collector body 2 and located between the end of the dust collector body 2 and the connecting sleeve 3. The spring has good elastic potential energy. It can deform under the action of external force and return to its original shape after the external force is removed. The elastic force generated thereby can drive the dust collector body 2 to return to its original shape.

[0074] To further protect the battery cells and extend the life of the battery cell dust collection device, please refer to Figure 1 and Figure 7 The battery cell dust collection device also includes a first buffer pad 5 and a second buffer pad 6. The first buffer pad 5 is connected to the dust collection body 2 and is located between the end of the dust collection body 2 and the reset member. The second buffer pad 6 is connected to the dust collection body 2 and is located at the end of the connecting sleeve 3 away from the base 1. The first buffer pad 5 is used to limit the maximum distance that the dust collection component moves when it resets in the direction away from the battery cell, and the second buffer pad 6 is used to limit the maximum distance that the driving component drives the dust collection component to move in the direction close to the battery cell.

[0075] The second cushion 6 limits the maximum distance the main body 2 can move when the driving mechanism drives it to cover the battery cells for vacuuming, preventing excessive displacement from directly impacting and damaging the battery cells. When the main body 2 is reset, the first cushion 5 limits the displacement of the main body 2, preventing the cleaning head 24 from colliding with the connecting sleeve 3 and causing damage to the cleaning head 24.

[0076] In some embodiments, the first buffer pad 5 and the second buffer pad 5 can be made of flexible materials such as silicone, rubber, etc., and the present invention does not limit this.

[0077] The above are only some or preferred embodiments of the present invention. Neither the text nor the drawings can limit the scope of protection of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the overall concept of the present invention, or direct / indirect application in other related technical fields are included in the scope of protection of the present invention.
