DETAILED DESCRIPTION

[0033] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application described and shown in the drawings here can be arranged and designed in various different configurations.

[0034] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for which protection is sought, but merely represents selected embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present application.

[0035] like Figures 1 to 3As shown, the dust collection mechanism 100 of some embodiments of the present application includes a bracket 110 and a dust collection assembly 120, the dust collection assembly 120 includes a dust collection seat 121 and a dust collection head 122, the dust collection seat 121 is installed on the bracket 110, the dust collection head 122 is installed on one side of the dust collection seat 121 along the first direction Z, the dust collection head 122 and the dust collection seat 121 have a first dust collection channel 123 connected inside, the first dust collection channel 123 extends along the first direction Z to the surface of the dust collection head 122 to form a first opening 1223. The surface of the dust collection head 122 is also provided with a second opening 1224, the dust collection head 122 has a second dust collection channel 124, and the second dust collection channel 124 connects the second opening 1224 with the first dust collection channel 123.

[0036] The dust collection mechanism 100 of the embodiment of the present application is used to remove dust from the battery 300, specifically, it refers to the semi-finished product after the groove rolling process is completed, that is, the shell part before the shell and the cover are packaged.

[0037] Specifically, after the dust collector head 122 is inserted into the shell opening, there is a gap between the dust collector head 122 and the inner edge of the shell opening. Under the action of negative pressure, the airflow passes through the gap between the dust collector head 122 and the shell opening and enters the interior of the shell, and then enters the dust collector head 122 from the first opening 1223 and the second opening 1224, thereby taking away dust and debris inside the shell and near the opening, thereby achieving a dust removal effect.

[0038] In the cross-sectional direction of the dust collector head 122 (i.e., the XY plane), the first opening 1223 is centrally arranged, and the second opening 1224 is offset from the center of the dust collector head 122 relative to the first opening 1223, so that the first opening 1223 mainly removes dust from the space inside the shell, and the second opening 1224 mainly removes dust from the space near the shell opening.

[0039] In some embodiments of the present application, the vacuum mechanism 100 is applied to cylindrical batteries, and correspondingly, the vacuum head 122 is cylindrical or hemispherical; in other embodiments, if the vacuum mechanism 100 is applied to square shell batteries, the vacuum head 122 should be square as a whole.

[0040] The dust collection head 122 of the dust collection mechanism 100 of the embodiment of the present application has a first opening 1223 and a second opening 1224. The first opening 1223 is used for negative pressure dust removal inside the shell of the battery 300, and the second opening 1224 is used for negative pressure dust removal near the shell opening of the battery 300, thereby having a better dust removal effect.

[0041] In some embodiments of the present application, a plurality of second openings 1224 are provided, and along the circumference of the vacuum head 122 , the plurality of second openings 1224 are circumferentially spaced apart on the surface of the vacuum head 122 .

[0042] For example, eight second openings 1224 are provided, and correspondingly, eight second dust suction channels 124 are also provided, and the second openings 1224 correspond to the second dust suction channels 124 one by one.

[0043] In other embodiments, the second opening 1224 may also be set to be one, and the one second opening 1224 is used to remove dust in the range near the shell opening where dust removal is required.

[0044] In some embodiments of the present application, the bracket 110 includes a bracket body 111 and a driving unit 112, the dust suction seat 121 is slidably installed on the bracket body 111 along a first direction Z, the driving unit 112 is slidably installed on the bracket body 111 along a first direction Z, the driving unit 112 is connected to the dust suction seat 121, and the driving unit 112 is configured to be connected to the execution end of an external driving mechanism to drive the dust suction assembly 120 to move.

[0045] The bracket 110 further includes a positioning portion 113 and a bearing portion 114. The bearing portion 114 is located along the first direction Z on the side of the dust collector head 122 away from the dust collector seat 121. Based on the embodiment in which the first direction Z is a vertical direction, the dust collector head 122 is arranged downward, the bearing portion 114 is located at the lower side of the dust collector head 122 and is used to carry the battery 300. The positioning portion 113 is arranged adjacent to the bearing portion 114 and is used to abut against the battery 300 to assist in fixing the battery 300. The housing opening of the battery 300 faces the dust collector head 122, so that the dust collector head 122 can extend into the housing opening for negative pressure dust removal.

[0046] The driving unit 112 is combined with an external driving mechanism to drive the dust collection assembly 120 to move, and then drive the dust collection head 122 to move, so that the dust collection head 122 extends into the interior of the shell to perform negative pressure dust removal.

[0047] It can be understood that in the embodiment of the present application, the dust collection component 120 is extended into the interior of the shell opening by using an external driving mechanism as a power source; in other embodiments, the dust collection mechanism 100 may also include an independent driving component to drive the dust collection component 120 to move.

[0048] Furthermore, the positioning portion 113 is provided with an abutting surface for abutting against the side wall of the battery 300 ; for example, the battery 300 is a cylindrical battery, and the abutting surface is a concave arc surface.

[0049] The dust suction seat 121 is provided with a first air joint 1211 , which is communicated with the first dust suction channel 123 and is used to be connected to an external negative pressure air source.

[0050] In some embodiments of the present application, the dust collector head 122 includes a bottom surface 1222 and an outer peripheral surface 1221, the bottom surface 1222 is located on the side of the dust collector head 122 away from the dust collector seat 121 along the first direction Z, the outer peripheral surface 1221 connects the dust collector seat 121 and the bottom surface 1222, the first opening 1223 is opened on the bottom surface 1222, and the second opening 1224 is at least partially opened on the outer peripheral surface 1221.

[0051] The second dust suction channel 124 extends along the radial direction of the dust suction head 122 , with one end extending to the surface of the dust suction head 122 to form a second opening 1224 , and the other end extending into the interior of the dust suction head 122 to communicate with the first dust suction channel 123 .

[0052] The first opening 1223 is centrally disposed on the bottom surface 1222 , and the second opening 1224 may be completely disposed on the outer peripheral surface 1221 , or may be disposed at the connection between the outer peripheral surface 1221 and the bottom surface 1222 .

[0053] In other embodiments, the second opening 1224 may also be opened at a portion of the bottom surface 1222 close to the outer peripheral surface 1221 .

[0054] In some embodiments of the present application, the second dust suction channel 124 is formed by a depression in the bottom surface 1222 , and the second opening 1224 is opened at the connection between the outer peripheral surface 1221 and the bottom surface 1222 .

[0055] That is to say, the second dust suction channel 124 is a slot structure of the bottom surface 1222, which extends to the outer peripheral surface 1221 to form a second opening 1224. The airflow enters the slot structure from the second opening 1224 and then enters the first dust suction channel 123 to perform negative pressure dust removal on the part near the shell opening.

[0056] In other embodiments, the second opening 1224 may also be completely disposed on the outer peripheral surface 1221 .

[0057] In some embodiments of the present application, the dust collection mechanism 100 further includes an elastic member 130 elastically connected along the first direction Z between the driving portion 112 and the dust collection seat 121 .

[0058] Specifically, the dust collection mechanism 100 further includes a slide rail assembly 140 , and the driving portion 112 and the dust collection seat 121 are both slidably matched with the bracket body 111 along the first direction Z through the slide rail assembly 140 .

[0059] The elastic member 130 is elastically connected between the bracket 110 and the dust suction seat 121 , so as to buffer the force exerted on the battery cell when the dust suction head 122 abuts against the surface of the battery cell inside the battery 300 , thereby reducing the risk of crushing the battery cell.

[0060] As an example form, the elastic member 130 is a mechanical spring; in other embodiments, the elastic member 130 may also be a gas spring.

[0061] Some embodiments of the present application further disclose a dust suction device 200, including a dust suction mechanism 100, for removing dust from the inside of a shell and the vicinity of an opening of a battery 300 after a groove rolling process, and for fully automatically removing dust from the battery 300.

[0062] like Figure 4 , Figure 5 and Figure 6 As shown, the dust suction device 200 includes a frame (not shown in the figure), a driving mechanism 220 and the aforementioned dust suction mechanism 100. The driving mechanism 220 is installed on the frame. The driving mechanism 220 is used to drive the dust suction mechanism 100 to move so that the dust suction head 122 extends into the shell opening of the battery 300 to perform negative pressure dust removal.

[0063] Driven by the driving mechanism 220 , the dust collecting mechanism 100 may move only along the first direction Z; or may move along other directions including the motion vector component of the first direction Z.

[0064] In some embodiments of the present application, the dust collecting device 200 further includes a spindle 210, which is fixedly mounted on the frame, and the axial direction of the spindle 210 extends along the first direction Z. The driving mechanism 220 includes a rotation driving assembly 221 and a guide cam 222. The rotation driving assembly 221 is mounted on the frame and is used to drive the dust collecting mechanism 100 to rotate around the spindle 210; the guide cam 222 is fixedly sleeved on the spindle 210, and the guide cam 222 has a circumferentially extending guide groove 2221. The bracket 110 includes a driving part 112, and the driving part 112 is inserted into the guide groove 2221. Driven by the rotation driving assembly 221, the driving part 112 is configured to move along the first direction Z while sliding along the guide groove 2221.

[0065] The central axis of the core shaft 210 is a first axis P, and the first axis P extends along a first direction Z. The guide cam 222 and the rotating sleeve 230 described below are both coaxially disposed with the core shaft 210 .

[0066] A dust collection station is provided on the circumference of the core shaft 210, and the driving mechanism 220 drives the dust collection mechanism 100 to move to the dust collection station. The battery 300 is placed on the bearing portion 114 of the bracket 110 and abuts against the positioning portion 113, and the dust collection head 122 extends into the shell opening for negative pressure dust removal.

[0067] The rotation drive assembly 221 includes a driving member (not shown in the figure), a transmission shaft 2211, a transmission gear 2212 and a rotating disk 2213. The axis of the transmission shaft 2211 extends along the first axis P. The transmission gear 2212 and the rotating disk 2213 are coaxially mounted on the transmission shaft 2211. The driving member is used to drive the transmission gear 2212 to rotate, thereby driving the rotating disk 2213 to rotate around the first axis P through the transmission shaft 2211. The bracket 110 is mounted on the rotating disk 2213. The rotating disk 2213 rotates to drive the dust collection mechanism 100 to rotate around the core shaft 210.

[0068] The driving part 112 includes a roller 1121, which is embedded in the guide groove 2221. When the dust collection mechanism 100 rotates around the core shaft 210, the trajectory of the roller 1121 along the guide groove 2221 changes in the first direction Z to drive the dust collection head 122 to extend into or away from the shell opening.

[0069] As an example, the continuous 180° angle range of the guide cam 222 in the circumferential direction is the dust collection station. Along the first direction Z, the trajectory of the portion of the guide groove 2221 corresponding to the dust collection station bends toward the bearing portion 114 of the dust collection mechanism 100, so as to drive the entire dust collection assembly 120 close to the battery 300 on the bearing portion 114, thereby extending into the shell opening for negative pressure dust removal. In the remaining 180° angle range of non-dust collection stations, the guide groove 2221 bends in a direction away from the bearing portion 114, thereby driving the entire dust collection assembly 120 away from the battery 300 on the bearing portion 114 and pulling it out of the shell opening.

[0070] For example, the non-dust suction stations within the remaining 180° angle range can be used as loading stations, and the dust suction mechanism 100 is docked with an external loading mechanism to receive the battery 300, and then drives the battery 300 to rotate to the dust suction station for negative pressure dust removal.

[0071] In some embodiments of the present application, a plurality of dust suction mechanisms 100 are provided, and the plurality of dust suction mechanisms 100 are spaced apart around the core shaft 210 .

[0072] For example, six dust suction mechanisms 100 are provided, and the six dust suction mechanisms 100 are arranged at intervals around the core shaft 210 , and the six brackets 110 are installed on the turntable 2213 of the rotation driving assembly 221 at intervals in the circumferential direction.

[0073] By providing a plurality of dust collection mechanisms 100, it is possible to synchronously remove dust from a plurality of batteries 300 in one cycle, or shorten the cycle time for each dust collection mechanism 100 to reach the dust collection station, thereby improving the dust removal efficiency.

[0074] like Figure 7 and Figure 8As shown, in some embodiments of the present application, the dust suction device 200 also includes a rotating sleeve 230, which is rotatably mounted on the core shaft 210; the rotating sleeve 230 has a third dust suction channel 231 inside, the core shaft 210 has a fourth dust suction channel 211 inside, the first dust suction channel 123 of the dust suction seat 121 is connected to the third dust suction channel 231, and the rotating sleeve 230 rotates around the core shaft 210 to switch the third dust suction channel 231 and the fourth dust suction channel 211 between the ventilation position and the non-ventilation position.

[0075] It is understandable that the rotating sleeve 230 rotates synchronously with the dust collection mechanism 100, and the synchronous rotation of the rotating sleeve 230 and the bracket 110 can be achieved by connecting the rotating sleeve 230 and the bracket 110, or by connecting the dust collection seat 121 and the rotating sleeve 230.

[0076] Through this arrangement, a negative pressure air source can be provided for each dust collection mechanism 100 , and the negative pressure air source of the dust collection head 122 can be connected or disconnected.

[0077] like Figure 8 and Fig. 9 As shown, in some embodiments of the present application, the outer circumferential surface of the core shaft 210 has a third opening 212 extending circumferentially, the third opening 212 is connected to the fourth dust suction channel 211, and the inner surface of the rotating sleeve 230 has a fourth opening 233 connected to the third dust suction channel 231;

[0078] When the third dust suction channel 231 and the fourth dust suction channel 211 are switched to the ventilation state, the fourth opening 233 is aligned with and communicates with the third opening 212;

[0079] When the third dust suction channel 231 and the fourth dust suction channel 211 are switched to a non-ventilated state, the fourth opening 233 and the third opening 212 are offset and not connected.

[0080] Through this arrangement, the switching of the third dust suction channel 231 and the fourth dust suction channel 211 between the ventilated state and the non-ventilated state can be simply and reliably achieved.

[0081] like Fig. 9 As shown, based on the aforementioned implementation of the continuous angle range of 180° of the core shaft 210 as a dust collection station, the third opening 212 is opened in the range corresponding to the dust collection station, and the extension angle is also 180°, which can provide a negative pressure air source for several dust collection mechanisms 100 in the dust collection station at the same time.

[0082] In some embodiments of the present application, Figure 1 As shown, the dust suction seat 121 is provided with a first air joint 1211, which is connected to the first dust suction channel 123; Figure 8As shown, the rotating sleeve 230 is provided with a second air connector 232 which is connected to the third dust suction channel 231 ; wherein the first air connector 1211 is connected to the second air connector 232 via a hose.

[0083] Since the first air joint 1211 is connected to the second air joint 232 through the hose, the dust suction seat 121 can be allowed to move along the first direction Z while the dust suction seat 121 and the rotating sleeve 230 rotate synchronously.

[0084] In some embodiments of the present application, the core shaft 210 is provided with a third air connector 213 which is in communication with the fourth dust suction channel 211 and is used for connecting to an external negative pressure air source.

[0085] The third gas connector 213 is disposed at the end of the core shaft 210 along the first axis P so as to be connected to an external negative pressure gas source.

[0086] like Figures 1 to 9 As shown, the working principles of the dust collection mechanism 100 and the dust collection device 200 of the embodiment of the present application are as follows:

[0087] Load the battery 300 onto the carrying portion 114 of the dust collecting mechanism 100 and abut against the positioning portion 113;

[0088] The rotary drive assembly 221 drives the plurality of dust collecting mechanisms 100 to rotate around the core shaft 210, so that the dust collecting mechanisms 100 enter the dust collecting stations in sequence / in groups;

[0089] The third opening 212 is connected to the fourth opening 233 of the rotating sleeve 230 corresponding to the dust collection mechanism 100 entering the dust collection station, thereby providing a negative pressure air source for the dust collection assembly 120. At this time, the fourth dust collection channel 211 and the third dust collection channel 231 are connected to the first dust collection channel 123;

[0090] Along the trajectory of the guide groove 2221, the vacuum head 122 extends into the shell opening of the battery 300. Under the action of negative pressure, the airflow enters the shell from the gap between the outer peripheral surface 1221 of the vacuum head 122 and the shell opening. The first opening 1223 is mainly used to remove dust from the internal space of the shell, and the second opening 1224 is mainly used to remove dust near the shell opening.

[0091] After dust removal is completed, the rotary drive assembly 221 drives the dust collection mechanism 100 to continue to rotate around the core shaft 210, and along the trajectory of the guide groove 2221, the driving part 112 drives the dust collection head 122 to be pulled out of the shell and circumferentially leave the dust collection station.

[0092] Using the dust collection mechanism 100 and the dust collection device 200 of the embodiment of the present application to perform negative pressure dust removal operations has a good dust removal effect on the inside and opening of the shell.
