[0047] The utility model is described in detail below in conjunction with the accompanying drawings.

[0048] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0049] During the assembly process of components such as batteries, bolts are often required to connect two components. However, during the bolt installation process, metal debris is often generated due to the friction between the screw hole surface of the component and the thread surface of the bolt. These metal debris remain in the battery and are likely to cause abnormalities such as short circuits, thereby causing safety hazards. In order to solve such technical problems, the technical solution of this application is produced. Figure 1 to Figure 6 To elaborate.

[0050] Example 1

[0051] Please refer to Figure 3 , Figure 4 and Figure 6 The present embodiment discloses a dust collection cylinder assembly 10, which may be provided with an adsorption structure, a mounting channel 11 and a dust collection channel 12. The mounting channel 11 and the dust collection channel 12 are both through-set.

[0052] The adsorption structure is used to make the dust collection tube assembly 10 adsorb and connect to the part 2, so that the dust collection tube assembly 10 remains in a fixed position. For example, if the part 2 is made of magnetic metal, the adsorption structure is a magnetic part arranged on the dust collection tube assembly 10, so that the dust collection tube assembly 10 is magnetically connected to the part 2, or the adsorption structure is a suction cup or an adsorption channel 13 described later, so that the dust collection tube assembly 10 is adsorbed and connected to the part 2.

[0053] The mounting channel 11 is used to correspond to the mounting hole 2a on the part 2, and the fastener 3 is used to be installed to the mounting hole 2a through the mounting channel 11; the fastener here can be a screw, a bolt, a stud, etc., and the mounting hole 2a is a threaded hole set for the corresponding fastener, so that the fastener 3 is threadedly connected to the part 2, and the fastener 3 can also be a rivet, so that the fastener 3 is riveted to the part 2.

[0054] The dust suction passage 12 is connected to the installation passage 11 and is connected to a second vacuum air pump 32 described later, so that debris and the like located in the installation passage 11 can be sucked away by the second vacuum air pump 32 .

[0055] like Figure 6 As shown, the fastener 3 may be a hexagon socket bolt, and the part 2 may be a component on the battery. Generally speaking, the fastener 3 is used to connect two adjacent parts 2, a portion of the mounting hole 2a forms a threaded hole portion on one of the two parts 2, and another portion of the mounting hole 2a forms a through hole portion on the other of the two parts 2. The dust collection tube assembly 10 is operated according to the following steps:

[0056] The dust collecting cylinder assembly 10 is placed on the part 2 having the through hole portion provided with the mounting hole 2a, and it is ensured that the mounting channel 11 corresponds to the mounting hole 2a.

[0057] The dust collection tube assembly 10 is adsorbed and connected to the part 2 through the adsorption structure to fix the dust collection tube assembly 10.

[0058] The fastener 3 is inserted into the adsorption channel 13 .

[0059] The second vacuum air pump 32 is turned on to produce an adsorption effect on the installation channel 11 through the dust suction channel 12 .

[0060] The fastener 3 is screwed into the mounting hole 2a by hand or with the help of a tool such as an Allen wrench. Specifically, the fastener 3 is screwed into the threaded hole portion of the mounting hole 2a through the through hole portion of the mounting hole 2a, so that the two parts 2 are connected to each other through the fastener 3.

[0061] During the process of screwing the fastener 3 into the threaded hole portion of the mounting hole 2a, metal debris generated by the friction between the two will be sucked out through the mounting hole 2a, the mounting channel 11 and the dust suction channel 12 in sequence, thereby preventing these metal debris from remaining in the battery and thus avoiding short circuits and other abnormalities, thereby improving the safety of the battery during the assembly process and subsequent use.

[0062] Optionally, the dust suction channel 12 can be arranged close to the side of the dust collection tube assembly 10 for fitting the part 2 to improve the dust removal effect of the dust collection tube assembly 10.

[0063] Optionally, as described above, the adsorption structure can be an adsorption channel 13 that is set through, and the adsorption channel 13 is set on one side of the installation channel 11. The adsorption channel 13 has an adsorption port that passes through the first fitting surface 10a of the dust collection tube assembly 10, the first fitting surface 10a is used to fit the surface of the part 2, and the adsorption port is used to be covered by the part 2. The adsorption channel 13 is connected to the first vacuum air pump 31 described later, so that the adsorption channel 13 can adsorb and fix the dust collection tube assembly 10 to the surface of the part 2 through the adsorption port. In this way, in the first aspect, the adsorption and fixation of the dust collection tube assembly 10 can be achieved without setting additional parts, reducing the amount of materials. In the second aspect, by controlling the on-off of the pipeline provided with the first vacuum air pump 31, the adsorption and fixation and release of the dust collection tube assembly 10 can be achieved, which is convenient for the use of the dust collection tube assembly 10.

[0064] Alternatively, if Figure 1 to Figure 3As shown, the adsorption channel 13 includes a first adsorption section 131 and a second adsorption section 132 connected to each other, and a plurality of second adsorption sections 132 are provided, where a plurality is understood as at least two, for example, three second adsorption sections 132 are provided, and are evenly distributed around the mounting channel 11. Among them, the side of the first adsorption section 131 away from the second adsorption section 132 is connected to the first vacuum air pump 31 through the first pipe joint 21 described later, and the opening of the second adsorption section 132 that passes through the first bonding surface 10a is the adsorption port.

[0065] In this way, by providing a plurality of second adsorption sections 132 , the dust collection tube assembly 10 has a plurality of adsorption points for adsorbing the parts 2 , so that the adsorption is more stable and the adsorption and fixing effect of the dust collection tube assembly 10 is better.

[0066] Optionally, the adsorption channel 13 may further include a transition adsorption section 133 respectively connecting the first adsorption section 131 and the second adsorption section 132. Specifically, the transition adsorption section 133 is respectively connected to the first adsorption section 131 and several second adsorption sections 132 are connected in parallel, so that the layout of the adsorption channel 13 of the present application is more reasonable.

[0067] Optionally, the transition adsorption section 133 can be arranged around the installation channel 11. For example, the transition adsorption section 133 is an annular channel. In this way, a plurality of second adsorption sections 132 can also be evenly distributed in a ring around the installation channel 11, so that the adsorption points of the dust collection tube assembly 10 are more evenly distributed, thereby improving the adsorption and fixing effect of the dust collection tube assembly 10.

[0068] Optionally, the opening direction of the second adsorption section 132 may be the same as the opening direction of the installation channel 11 to facilitate processing and manufacturing.

[0069] It should be pointed out here that the corresponding relationship between the first adsorption section 131 and the dust suction channel 12 is not limited in this embodiment. For example, the first adsorption section 131 and the dust suction channel 12 can be respectively arranged on two opposite sides of the dust removal cylinder assembly 10 along its own radial direction so as to be dispersed as much as possible to prevent them from being arranged too closely to each other. Of course, the first adsorption section 131 and the dust suction channel 12 can also be arranged in other ways.

[0070] Similarly, the corresponding relationship between the first adsorption section 131 and the second adsorption section 132 is not limited in this embodiment, as long as they are connected to each other, for example, the first adsorption section 131 and the second adsorption section 132 can be arranged correspondingly along the extension direction of the central axis of the dust removal cylinder assembly 10, or they can be staggered with each other, which will not be described in detail here.

[0071] Example 2

[0072] This embodiment further introduces the structure of the dust removal cylinder assembly 10 based on the embodiment 1, as described below:

[0073] The dust collection cylinder assembly 10 may include a first connecting cylinder 101 and a second connecting cylinder 102 sequentially arranged along the opening direction of the installation channel 11, the first adsorption section 131 and the transition adsorption section 133 may be arranged on the first connecting cylinder 101, and at least part of the second adsorption section 132 is arranged on the second connecting cylinder 102. This combined structure facilitates the processing and manufacturing of the adsorption channel 13, and facilitates the maintenance and replacement of related parts of the dust collection cylinder assembly 10.

[0074] Optionally, the transition adsorption section 133 forms an annular opening on the surface of the first connecting tube 101 facing the second connecting tube 102, the second connecting tube 102 covers the annular opening, and the second adsorption section 132 corresponds to the annular opening. This facilitates the processing and manufacturing of the transition adsorption section 133 without affecting the adsorption performance of the adsorption channel 13.

[0075] Optionally, one of the first connecting tube 101 and the second connecting tube 102 is provided with a recessed portion 1011 surrounding the installation channel 11, and the other is provided with a raised portion 1021 surrounding the installation channel 11, and the raised portion 1021 is accommodated in the recessed portion 1011. For example, the first connecting tube 101 is provided with a recessed portion 1011 on a side facing the second connecting tube 102, and the raised portion 1021 is provided on a side facing the first connecting tube 101. Alternatively, the first connecting tube 101 is provided with a raised portion 1021 on a side facing the second connecting tube 102, and the recessed portion 1011 is provided on a side facing the first connecting tube 101. Such a concave-convex combination can improve the sealing performance of the installation channel 11 and prevent the formation of a gap between the first connecting tube 101 and the second connecting tube 102, which may cause air leakage and other abnormalities.

[0076] Optionally, an internal thread may be provided on the circumference of the recessed portion 1011, and an external thread may be provided on the circumference of the raised portion 1021, so that the first connecting tube 101 and the second connecting tube 102 are connected by threads, which is convenient for subsequent maintenance and replacement. The recessed portion 1011 and the raised portion 1021 may also be connected by bonding, welding, interference fit, etc., to achieve connection between the first connecting tube 101 and the second connecting tube 102.

[0077] Optionally, in order to further improve the sealing performance, a sealing ring, a sealant, etc. may be provided between the first connecting tube 101 and the second connecting tube 102, which will not be described in detail here.

[0078] Optionally, the dust collection tube assembly 10 may further include a suction ring 103, which is arranged on the side of the second connecting tube 102 away from the first connecting tube 101, the installation channel 11 sequentially passes through the first connecting tube 101, the second connecting tube 102 and the suction ring 103, the second suction section 132 sequentially passes through the suction ring 103 and the second connecting tube 102, the first fitting surface 10a and the suction port are both located on the suction ring 103, and the hardness of the suction ring 103 is less than that of the second connecting tube 102. For example, the suction ring 103 can be set as a sponge pad. Since the suction ring 103 is made of a relatively soft material, when the dust collection tube assembly 10 is adsorbed and connected to the part 2, the suction ring 103 can be squeezed and deformed by the extrusion force generated between the dust collection tube assembly 10 and the part 2, so that the suction ring 103 is closely attached to the surface of the part 2, so that the suction ring 103 eliminates the gap between the suction ring 103 and the part 2, thereby improving the fitting degree and sealing effect between the dust collection tube assembly 10 and the part 2, and thus improving the adsorption and fixing effect of the dust collection tube assembly 10.

[0079] Optionally, the adsorption ring 103 and the second connecting tube 102 may be bonded to ensure connection stability.

[0080] Optionally, the dust suction channel 12 can be arranged on one side of the second connecting tube 102 close to the adsorption ring 103 to ensure the dust removal effect of the dust removal tube assembly 10.

[0081] Example 3

[0082] This embodiment further discloses a dust removal device based on the embodiment 2, which is described in detail as follows:

[0083] like Figure 5 and Figure 6 As shown, the dust removal device may include a dust removal cylinder assembly 10, a first pipe joint 21, a second pipe joint 22, a first control valve 41, a first vacuum air pump 31, a second vacuum air pump 32, and a second control valve 42. The first pipe joint 21 is connected to the adsorption channel 13, the second pipe joint 22 is connected to the dust suction channel 12, the first vacuum air pump 31 is connected to the first pipe joint 21 through the first control valve 41, and the second vacuum air pump 32 is connected to the second pipe joint 22 through the second control valve 42. The first pipe joint 21 and the second pipe joint 22 can be set as an elbow, a straight pipe joint, etc. according to the specific needs of the pipeline layout, and the first control valve 41 and the second control valve 42 can be selected from electromagnetic valves, etc.

[0084] The dust removal device works according to the following steps:

[0085] Perform the hole alignment step: fit the first fitting surface 10a of the dust removal cylinder assembly 10 to the surface of the component 2, and make the mounting channel 11 correspond to the mounting hole 2a.

[0086] Open the first control valve 41 so that the first vacuum air pump 31 can pass through the first control valve 41, the first pipe joint 21, and the adsorption channel 13 to make the dust collection tube assembly 10 adsorbed and connected to the part 2 to fix the dust collection tube assembly 10 at the current position.

[0087] The second control valve 42 is opened so that the second vacuum air pump 32 can remove dust from the installation channel 11 through the second control valve 42 , the second pipe joint 22 , and the dust suction channel 12 .

[0088] The fastener 3 is installed in the installation hole 2 a through the installation channel 11 , so that two adjacent parts 2 are connected by the fastener 3 .

[0089] The second control valve 42 is closed to stop the dust removal process on the installation passage 11 .

[0090] The first control valve 41 is closed to release the suction connection of the dust removal cylinder assembly 10 to the part 2 .

[0091] Return to the hole alignment step to prepare for installing the fastener 3 for another mounting hole 2a on the part 2.

[0092] In this way, all mounting holes 2a on part 2 can be installed with fasteners 3. This process can realize dust-free processing of fastener 3 installation, so as to prevent metal debris generated during the installation of fastener 3 to mounting hole 2a from remaining in the battery, thereby avoiding abnormalities such as short circuit, and improving the safety of battery assembly process and subsequent use. The second control valve 42 and the first control valve 41 can control the on-off timing of the relevant pipelines, making the operation of the dust removal device of the present application more intelligent.

[0093] Optionally, the present embodiment does not limit the positional relationship between the first pipe joint 21 and the second pipe joint 22. The first pipe joint 21 and the second pipe joint 22 can be respectively arranged on two opposite sides of the dust removal cylinder assembly 10 along its own radial direction, so as to disperse the dust removal devices and prevent them from being arranged too closely. The first pipe joint 21 and the second pipe joint 22 can also be arranged according to other positional relationships, and are no longer mutually related here.

[0094] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
