[0002] The solder produced by the welding device is cleaned by a dust suction device. The brush of the dust suction device can brush up the welding slag attached to the workpiece, and then it is sucked and cleaned by the dust suction pipe of the dust suction device. After the brush is seriously worn out during use, it needs to be replaced with a new brush. However, the efficiency of removing the brush is low. Utility Model Content

[0003] The main technical problem solved by the present application is to provide a dust removal mechanism, a dust removal device and a battery manufacturing equipment to solve the problem of low efficiency in disassembling the brush.

[0004] In order to solve the above technical problems, the first technical solution adopted by the present application is: to provide a dust removal mechanism. The dust removal mechanism may include a dust suction pipe, a mounting member, a brush assembly and a connecting member. The mounting member is connected to the dust suction pipe, and at least part of the mounting member is located in the dust suction pipe. At least part of the brush assembly is located in the dust suction pipe. The connecting member is movably arranged on the mounting member; the connecting member is used to connect the brush assembly to the mounting member or disconnect it. Among them, the dust suction pipe has an opening, and the orthographic projection of the connecting member on the contour surface of the opening is located within the contour surface of the opening. The opening is provided to facilitate the user to operate the connecting member, so that the connecting member can move relative to the mounting member. The connecting member disconnects the brush assembly from the mounting member, so that the brush assembly is separated from the connecting member and the mounting member, and the brush assembly can be removed from the dust suction pipe, thereby avoiding the user reaching into the second pipe opening of the dust suction pipe to remove the bolt, thereby improving the removal efficiency of the brush assembly. The connecting member connects the brush assembly to the mounting member, so that the brush assembly is installed in the dust suction pipe, thereby improving the installation efficiency of the brush assembly. Since both the disassembly efficiency and the installation efficiency of the brush assembly are improved, the replacement efficiency of the brush assembly is improved.

[0005] In some embodiments, the mounting member has a first channel; at least part of the connecting component is movable and arranged in the first channel; the first channel can expose the connecting component located in the first channel, and the orthographic projection of the first channel on the contour surface of the opening is located in the contour surface of the opening. In this way, the connecting component in the first channel can be operated by the opening and through the first channel, so that the connecting component moves.

[0006] In some embodiments, the connecting assembly includes a moving part and a matching part; the moving part is movably arranged in the first channel; the matching part is connected to the moving part; the moving part is used to drive the matching part to move; the matching part is used to connect the brush assembly to the mounting member or disconnect it.

[0007] In some embodiments, the mounting member further has a second channel and a plug-in slot; the second channel is connected to the plug-in slot; the mating portion passes through the second channel to connect the brush assembly to the plug-in slot. In this way, when the mating portion is away from the brush assembly, the mating portion withdraws from the plug-in slot, and the brush assembly is blocked by the plug-in slot, so that the brush assembly does not move with the mating portion. At this time, the brush assembly slides out of the plug-in slot, and the brush assembly is removed from the dust collection tube.

[0008] In some embodiments, the matching part is a plug, and the brush assembly has a socket; the plug can be plugged into the second channel and the socket. In this way, the brush assembly can be quickly installed or removed by plugging the plug with the second channel and the socket.

[0009] In some embodiments, the connection assembly further comprises a connection part; the connection part is located in the dust suction pipe; the movable part is detachably connected to the connection part, and the connection part is detachably connected to the matching part. In this way, it is convenient to assemble the connection part, the movable part and the matching part in the dust suction pipe.

[0010] In some embodiments, the direction in which the moving part drives the matching part to move intersects with the axial direction of the dust suction pipe. In this way, the size of the moving part in the axial direction of the dust suction pipe can be reduced. In addition, the dust suction pipe is usually in a vertical state, which is convenient for the user to operate the moving part using the opening.

[0011] In some embodiments, the moving part is slidably disposed in the first channel; the connecting assembly further comprises an elastic member; the elastic member is located in the first channel; one end of the elastic member is connected to the first channel, and the other end of the elastic member is connected to the moving part. In this way, when a tool is inserted into the first channel to push the moving part to slide in the first channel, the moving part will drive the matching part to move synchronously; at this time, the moving part will squeeze the elastic member, so that the elastic force of the elastic member increases. Then, after removing the tool, the elastic member of the elastic member can be used to drive the moving part to reset (i.e., slide in the opposite direction).

[0012] In some embodiments, the mounting member further includes a first limiting portion and a second limiting portion; the first limiting portion and the second limiting portion are spaced apart and arranged in the first channel; the moving portion includes a first sliding rod and a second sliding rod connected; the first sliding rod and the second sliding rod are both slidably arranged in the first channel, and the second sliding rod is located between the first limiting portion and the second limiting portion; the first sliding rod is connected to the matching portion; the first channel can expose the second sliding rod. In this way, a tool is used to pass through the first channel to push the second sliding rod to slide in the first channel between the first limiting portion and the second limiting portion, the second sliding rod can drive the first sliding rod to move, and the first sliding rod can drive the matching portion to move. The first limiting portion and the second limiting portion are set to limit the second sliding rod in the first channel.

[0013] In some embodiments, the first channel includes a first sub-channel, a second sub-channel, and a third sub-channel that are connected in sequence; the inner diameter of the first sub-channel is smaller than the inner diameter of the second sub-channel, and the first limiting portion is a step surface between the first sub-channel and the second sub-channel; the inner diameter of the third sub-channel is smaller than the inner diameter of the second sub-channel, and the second limiting portion is a step surface between the third sub-channel and the second sub-channel; the first slide bar is slidably arranged in the first sub-channel; the second slide bar is slidably arranged in the second sub-channel; the third sub-channel exposes the second slide bar in the second sub-channel, and the positive projection of the third sub-channel on the contour surface of the opening is located within the contour surface of the opening. In this way, the second slide bar in the second sub-channel is pushed to slide by a tool through the third sub-channel, and the second slide bar can drive the movement of the first slide bar in the first sub-channel, and the first slide bar can drive the matching portion to move. The first sub-channel and the third sub-channel can limit the second slide bar in the second sub-channel.

[0014] In some embodiments, the mounting member includes a first mounting member and a second mounting member; the first mounting member and the second mounting member are detachably connected; the first mounting member or the second mounting member is connected to the dust suction pipe; the first mounting member has a first sub-channel and a second sub-channel; the second mounting member has a third sub-channel. In this way, when the first mounting member and the second mounting member are detached, the connected first sliding rod and the second sliding rod can be taken out of the first sub-channel and the second sub-channel, so as to facilitate the replacement of the moving part.

[0015] In some embodiments, the brush assembly includes a brush holder and a brush; the brush holder and the brush are detachably connected; and the brush holder is connected to the connecting assembly. In this way, the connecting assembly is connected to the brush holder, reducing the risk of damaging the brush, and only the brush needs to be replaced, and the brush holder can be reused.

[0016] In some embodiments, the dust removal mechanism further includes a telescopic assembly; the telescopic assembly is disposed outside the dust suction pipe; a portion of the mounting member is located inside the dust suction pipe; another portion of the mounting member passes through the opening and is connected to the telescopic assembly; the telescopic assembly is used to drive the mounting member to move along the axial direction of the dust suction pipe in the opening. In this way, the telescopic assembly can be used to drive the mounting member to move along the axial direction of the dust suction pipe in the opening, so that the brush mechanism on the mounting member can extend out of the second pipe opening of the dust suction pipe or retract into the second pipe opening. Part of the mounting member extends out of the opening to facilitate the connection between the mounting member and the telescopic assembly.

DETAILED DESCRIPTION

[0030] The scheme of the embodiment of the present application is described in detail below in conjunction with the drawings of the specification.

[0031] In the following description, for the purpose of explanation rather than limitation, specific details such as specific system structures, interfaces, and technologies are provided to facilitate a thorough understanding of the present application.

[0032] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0033] The terms "first", "second", "third" in this application are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, the features defined as "first", "second", "third" can expressly or implicitly include at least one of the features. In the description of this application, the meaning of "multiple" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined. In the embodiments of this application, all directional indications (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication also changes accordingly. In addition, the terms "including" and "having" and any of their variations are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device comprising a series of steps or units is not limited to the steps or units listed, but optionally also includes steps or units that are not listed, or optionally also includes other steps or units inherent to these processes, methods, products or devices.

[0034] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] In the related art, when a welding device is welding a workpiece, the welding device will produce welding slag and the like, and a dust suction device is used to clean the solder produced by the welding device. The brush of the dust suction device can brush up the welding slag attached to the workpiece, and then it is sucked and cleaned by the dust suction pipe of the dust suction device. After the brush is severely worn during use, it is necessary to replace it with a new brush. However, since the brush is connected and fixed to the brush mounting part inside the dust suction pipe by bolts, and the bolts are inside the dust suction pipe and the dust suction port. When removing the bolts, the weld mark dust suction port needs to be removed from the dust suction pipe first, exposing the bolt mounting part, and then the brush can be replaced, which makes the removal efficiency of the brush low.

[0036] In order to solve the problem of low efficiency of brush removal. An embodiment of the present application provides a dust removal mechanism. The dust removal mechanism may include a dust suction pipe, a mounting member, a brush assembly and a connecting member. The mounting member is connected to the dust suction pipe, and at least part of the mounting member is located in the dust suction pipe. At least part of the brush assembly is located in the dust suction pipe. The connecting member is movably arranged on the mounting member; the connecting member is used to connect the brush assembly to the mounting member or disconnect it. Among them, the dust suction pipe has an opening, and the orthographic projection of at least part of the connecting member on the contour surface of the opening is located within the contour surface of the opening. In this way, the opening is set so that at least part of the connecting member is exposed to the outside of the dust suction pipe, which is convenient for users to operate the connecting member, so that the connecting member can move relative to the mounting member. The movement of the connecting member can disconnect the brush assembly from the mounting member, so that the brush assembly and the mounting member can be separated, and the brush assembly can be removed from the dust suction pipe, thereby avoiding the user reaching into the second pipe opening of the dust suction pipe to remove the bolt, thereby improving the disassembly efficiency of the brush assembly. The movement of the connecting assembly can connect the brush assembly to the mounting member, so that the brush assembly is installed in the dust suction pipe, thereby improving the installation efficiency of the brush assembly. Since the removal efficiency and installation efficiency of the brush assembly are both improved, the replacement efficiency of the brush assembly is improved.

[0037] The embodiment of the present application provides a battery manufacturing device. Figure 1 The battery manufacturing equipment may include a welding device 2 and a dust removal device 1; the dust removal device 1 is used to clean impurities generated by the welding device 2 so as to reduce pollution to the welding workpiece or the environment.

[0038] The welding device 2 can be a manual arc welding device, a submerged arc welding device, a CO 2 Gas shielded welding device, MIG inert gas shielded welding device, laser welding device or ultrasonic welding device, etc. The welding device 2 is installed at the first preset station and can weld the workpiece to be welded.

[0039] The dust removal device 1 is installed at the second preset station, and the dust removal device 1 can clean impurities such as solder and gas generated by the welding device 2. Of course, the dust removal device 1 can also clean impurities generated by other devices. For example, other devices of the battery manufacturing equipment can be forming devices. When the forming device forms a workpiece (for example, the tab forming device forms the tab), dust will be generated. The dust suction device can be used to clean the dust generated by the forming device.

[0040] In some examples, the first preset station and the second preset station may be the same station, in which case the welding device 2 and the dust collecting device are installed on the same station. In other examples, the first preset station and the second preset station may be different stations.

[0041] The first preset station can be understood as a position where the welding device 2 can be installed. The second preset station can be understood as a position where a dust collecting device can be installed. For example, the battery manufacturing equipment also includes a mounting frame (which can be understood as a frame structure, or can be understood as a solid structure such as a block or a plate), and the mounting frame has a first preset station and a second preset station. For another example, the ground has a first preset station and a second preset station.

[0042] The dust removal device 1 can be applied to the field of battery manufacturing, and the dust removal device 1 can be used to clean impurities generated when preparing the battery. For example, the dust removal device 1 can clean the solder and gas generated by the welding of the top cover and the adapter. For another example, the dust removal device 1 can also clean the dust and dust generated by the ear forming process. The battery can be a lithium-ion secondary battery, a lithium-ion primary battery, a lithium-sulfur battery, a sodium-lithium-ion battery, a sodium-ion battery or a magnesium-ion battery. The dust removal device 1 can also be applied to other fields, such as the vehicle manufacturing field, the fixture manufacturing field, etc.

[0043] The embodiment of the present application also provides a dust removal device. Figure 1 The dust removal device 1 includes an air suction mechanism 12 and a dust removal mechanism 11. The air suction mechanism 12 is connected to a dust suction pipe 111 of the dust removal mechanism 11. In this way, the air suction mechanism 12 can be used to make the dust suction pipe 111 of the dust removal mechanism 11 absorb impurities.

[0044] The suction mechanism 12 may be a device that can provide negative air pressure to generate suction. For example, the suction mechanism 12 may be an exhaust fan, an air pump, etc. In some examples, the dust removal device 1 further includes a power supply, which is electrically connected to the suction mechanism 12 to provide electrical energy to the exhaust fan. In some examples, the dust removal device 1 further includes a controller, which is electrically connected to the suction mechanism 12, and the controller controls the start and stop of the suction mechanism 12.

[0045] The embodiment of the present application also provides a dust removal mechanism. The dust removal mechanism can be found in Figure 2 to Figure 9 See also Figure 2 to Figure 4 The dust removal mechanism 11 includes a dust suction pipe 111, a mounting member 114, a brush assembly 117 and a connecting member 116. The mounting member 114 is connected to the dust suction pipe 111, and at least a portion of the mounting member 114 is located in the dust suction pipe 111. At least a portion of the brush assembly 117 is located in the dust suction pipe 111. The connecting member 116 is movably disposed on the mounting member 114; the connecting member 116 is used to connect the brush assembly 117 to the mounting member 114 or disconnect it. The dust suction pipe 111 has an opening 1113, and the orthographic projection of at least a portion of the connecting member 116 on the contour surface of the opening 1113 is located within the contour surface of the opening 1113.

[0046] In this way, the opening 1113 is provided so that at least part of the connecting assembly 116 is exposed outside the dust suction pipe 111, which is convenient for the user to operate the connecting assembly 116, so that the connecting assembly 116 can move relative to the mounting member 114. The movement of the connecting assembly 116 can disconnect the brush assembly 117 from the mounting member 114, so that the brush assembly 117 and the mounting member 114 can be separated, and the brush assembly 117 can be removed from the dust suction pipe 111, thereby avoiding the user reaching into the second pipe opening of the dust suction pipe 111 to remove the bolts, thereby improving the removal efficiency of the brush assembly 117. The movement of the connecting assembly 116 can connect the brush assembly 117 to the mounting member 114, so that the brush assembly 117 is installed in the dust suction pipe 111, thereby improving the installation efficiency of the brush assembly 117. Since the removal efficiency and installation efficiency of the brush assembly 117 are improved, the replacement efficiency of the brush assembly 117 is improved.

[0047] The dust suction tube 111 can be understood as a tubular structure, which can be an integrally formed structure or a combined structure. Figure 5 , the dust suction pipe 111 may have a first pipe opening and a second pipe opening; the first pipe opening may be connected to the suction mechanism 12, and the second pipe opening may be used to absorb impurities, and the opening 1113 is provided on the side wall; that is, the opening 1113 is not the first pipe opening and the second pipe opening of the dust suction pipe 111. In some examples, the dust suction pipe 111 may include a dust suction main pipe 1111 and a dust suction head 1112; the dust suction main pipe 1111 is connected to the suction mechanism 12; the dust suction head 1112 is connected to the dust suction main pipe 1111, and the dust suction head 1112 is detachably connected to the dust suction main pipe 1111; so as to facilitate the replacement of the dust suction head 1112. The dust suction head 1112 may be a constricted structure (for example, Figure 2 The trumpet shape shown in the figure) can make the port of the dust collector head 1112 have greater suction force.

[0048] The mounting member 114 may be a single structure, or a combination of multiple structures (e.g., the mounting member 114 may include a first mounting member 1141 and a second mounting member 1142 connected). The brush assembly 117 may be a brush 1172; the brush assembly 117 may include a combination of the brush 1172 and other structures (e.g., the brush assembly 117 may include the brush 1172 and the brush holder 1171 described below).

[0049] The orthographic projection of at least part of the connecting component 116 on the contour surface of the opening 1113 is located within the contour surface of the opening 1113. For example, the orthographic projection of part of the connecting component 116 on the contour surface of the opening 1113 is located within the contour surface of the opening 1113. For another example, the orthographic projection of the entire connecting component 116 on the contour surface of the opening 1113 is located within the contour surface of the opening 1113. The contour surface of the opening 1113 can be understood as a surface formed by the contour line of the opening 1113.

[0050] At least part of the connecting component 116 is located in the dust suction tube 111. In some examples, for example, the connecting component 116 is entirely located in the dust suction tube 111, and the opening 1113 can expose at least part of the connecting component 116, and at least part of the connecting component 116 can be seen through the opening 1113. A tool is inserted from the opening 1113 into the dust suction tube 111 to operate at least part of the connecting component 116, so that the connecting component 116 moves.

[0051] In other examples, a portion of the connecting component 116 is located in the dust suction tube 111, and another portion of the connecting component 116 extends out of the dust suction tube 111 from the opening 1113; at this time, a tool is used to operate the connecting component 116 extending out of the opening 1113 to move the connecting component 116.

[0052] The connecting assembly 116 is movably arranged on the mounting member 114. It can be understood that the connecting assembly 116 is connected to the mounting member 114, and the connecting assembly 116 can move relative to the mounting member 114; for example, sliding or spiral movement, so that the connecting assembly 116 can be close to or away from the brush assembly 117. When the connecting assembly 116 is close to the brush assembly 117, the connecting assembly 116 connects the brush assembly 117 to the mounting member 114, so that the brush assembly 117 is installed in the dust suction pipe 111. When the connecting assembly 116 is away from the brush assembly 117, the connecting assembly 116 disconnects the brush assembly 117 from the mounting member 114, so that the brush assembly 117 can be separated from the mounting member 114, and the brush assembly 117 can be removed from the dust suction pipe 111.

[0053] The connecting component 116 is used to connect the brush component 117 to the mounting member 114. It can be understood that the connecting component 116 locks the brush component 117 to the mounting member 114 to form a whole, and the brush component 117 and the mounting member 114 cannot be separated. The connecting component 116 is used to release the connection. It can be understood that the brush component 117 and the mounting member 114 are unlocked and can be separated.

[0054] Since the connection component 116 may include a variety of structures, for example, the connection component 116 may include a bolt, a buckle structure, a magnetic attraction mechanism, etc., so that there are a variety of ways to connect the connection component 116, the brush component 117 and the mounting member 114. For example, the connection component 116 may be a bolt, the bolt threading the brush component 117 to the mounting member 114, and the bolt is screwed out of the brush component 117 and the mounting member 114. For another example, the connection component may be a latch, the latch plugs the brush component 117 to the mounting member 114, and the latch is pulled out of the brush component 117 and the mounting member 114. For another example, the connection component 116 may be a buckle, the buckle clamps the brush component 117 to the mounting member 114, and the buckle is separated from the brush component 117 and the mounting member 114. Of course, the connection component 116 may also include embodiments of the moving portion 1162 and the matching portion 1164.

[0055] In some embodiments, the mounting member 114 has a first channel 1143; at least part of the connecting component 116 is movably disposed in the first channel 1143; the first channel 1143 can expose the connecting component 116 located in the first channel 1143, and the orthographic projection of the first channel 1143 on the contour surface of the opening 1113 is located in the contour surface of the opening 1113. In this way, the connecting component 116 in the first channel 1143 can be operated by using the opening 1113 and through the first channel 1143, so that the user can operate the connecting component 116 conveniently.

[0056] At least part of the movement of the connecting component 116 is set in the first channel 1143, which can be understood as at least part of the connecting component 116 is located in the first channel 1143, and the connecting component 116 can move relative to the first channel 1143. In some examples, the entire movement of the connecting component 116 is set in the first channel 1143, part of the brush component 117 can extend into the first channel 1143, and the connecting component 116 can be connected to the part of the brush component 117 extending into the first channel 1143, so that the connecting component 116 installs the brush component 117 on the mounting member 114; in this case, the connecting component 116 can be a bolt, a latch, etc. In other examples, when a portion of the connecting component 116 is movably disposed in the first channel 1143 and another portion is located outside the first channel 1143, the connecting component 116 may include a connecting movable portion 1162 and a matching portion 1164 described below, wherein the entire movable portion 1162 is movably disposed in the first channel 1143, and the matching portion 1164 may be disposed outside the first channel 1143.

[0057] Of course, the mounting member 114 may also not have the first channel 1143, and the connecting component 116 may be movably set on the surface of the mounting member 114, so that the connecting component 116 can move on the surface of the mounting member 114; for example, a slide groove is provided on the surface of the mounting member 114, and the slider of the connecting component 116 is slidably set in the slide groove; for another example, a guide rail is provided on the surface of the mounting member 114, and the slider of the connecting component 116 is slidably set on the guide rail.

[0058] The first channel 1143 may have a first opening and a second opening, the second opening is located in the dust suction tube 111, and the first opening is located in the dust suction tube 111 or outside the dust suction tube 111. Then, the first channel 1143 can expose the connection component 116 located in the first channel 1143, which can be understood as the first opening of the first channel 1143 can expose the connection component 116 in the first channel 1143. The orthographic projection of the first channel 1143 on the contour surface of the opening 1113 is located within the contour surface of the opening 1113, which can be understood as the orthographic projection of the first opening of the first channel 1143 on the contour surface of the opening 1113 is located within the contour surface of the opening 1113. In some examples, the entirety of the mounting member 114 is located inside the dust suction tube 111; the first opening and the second opening are both located inside the dust suction tube 111; since the orthographic projection of the first channel 1143 on the contour surface of the opening 1113 is located inside the contour surface of the opening 1113, the opening 1113 exposes the first opening of the first channel 1143, that is, exposes part of the connecting assembly 116. In other examples, a portion of the mounting member 114 is located inside the dust suction tube 111, and another portion is located outside the dust suction tube 111; the second opening is located inside the dust suction tube 111, and the first opening is located outside the dust suction tube 111; that is, the first channel 1143 extends from the mounting member 114 outside the dust suction tube 111 to the mounting member 114 inside the dust suction tube 111, and part of the connecting assembly 116 is exposed outside the dust suction tube 111 through the first opening.

[0059] In some embodiments, the connecting assembly 116 includes a moving portion 1162 and a matching portion 1164; the moving portion 1162 is movably disposed in the first channel 1143; the matching portion 1164 is connected to the moving portion 1162; the moving portion 1162 is used to drive the matching portion 1164 to move; the matching portion 1164 is used to connect the brush assembly 117 to the mounting member 114 or disconnect it. In this way, the moving portion 1162 and the matching portion 1164 can be disposed in different channels, so that the moving portion 1162 is exposed outside the dust suction pipe 111.

[0060] In some examples, the moving part 1162 may be slidably disposed in the first channel 1143, and in this case, the moving part 1162 may be a shaft-like structure, such as a sliding rod, etc. In other examples, the moving part 1162 may also be threadedly connected in the first channel 1143; in this case, the moving part 1162 may be a screw, and the first channel 1143 may be a threaded hole, and the moving part 1162 moves in the first channel 1143 by rotating the thread.

[0061] The matching portion 1164 is connected to the moving portion 1162, that is, the moving portion 1162 is connected to the matching portion 1164 through the second opening; for example, part of the moving portion 1162 extends out of the second opening and is connected to the matching portion 1164; for another example, the matching portion 1164 extends from the second opening into the first channel 1143 and is connected to the moving portion 1162. In this way, the moving portion 1162 moves in the first channel 1143, which can drive the matching portion 1164 to move, so that the matching portion 1164 is close to or away from the brush assembly 117. In some examples, the matching portion 1164 and the moving portion 1162 can be directly connected; for example, the matching portion 1164 and the moving portion 1162 are welded. In other examples, the matching portion 1164 and the moving portion 1162 can be indirectly connected; for example, the matching portion 1164 is connected to the moving portion 1162 through the connecting portion 1163.

[0062] The matching portion 1164 may be a structure capable of fixing the brush assembly 117 on the mounting member 114, and the matching portion 1164 may be a buckle structure, a latch, etc. For example, the matching portion 1164 may be a latch, by which the brush assembly 117 may be plugged and fixed on the mounting member 114; for another example, the matching portion 1164 may be a buckle structure, by which the brush assembly 117 may be buckled and fixed on the mounting member 114.

[0063] In some embodiments, the mounting member 114 further has a second channel 1144 and a plug-in slot 1145; the second channel 1144 is in communication with the plug-in slot 1145; the matching portion 1164 passes through the second channel 1144 and can connect and fix the brush assembly 117 in the plug-in slot 1145. In this way, when the matching portion 1164 moves away from the brush assembly 117, the matching portion 1164 withdraws from the plug-in slot 1145, and the brush assembly 117 is blocked by the plug-in slot 1145, so that the brush assembly 117 does not move with the matching portion 1164. At this time, the brush assembly 117 can slide out of the plug-in slot 1145, and the brush assembly 117 is removed from the dust collection tube 111.

[0064] In some examples, the axis of the first channel 1143 and the axis of the second channel 1144 can be parallel, so that the moving part 1162 can move in the first channel 1143 and the matching part 1164 can move in the second channel 1144, making the operation easier. The slot of the plug-in slot 1145 faces the first pipe opening of the dust suction pipe 111, and the brush assembly 117 can be plugged into the plug-in slot 1145 through the first pipe opening. The plug-in direction of the brush assembly 117 in the plug-in slot 1145 is perpendicular to the axis of the second channel 1144. The second channel 1144 is provided on the side wall of the plug-in slot 1145.

[0065] In some embodiments, the matching portion 1164 is a plug, and the brush assembly 117 has a socket; the plug can be plugged into the second channel 1144 and the socket. In this way, the brush assembly 117 can be quickly installed or removed by plugging the plug with the second channel 1144 and the socket.

[0066] The brush assembly 117 is inserted into the insertion groove 1145 , and the axial direction of the insertion hole coincides with the axial direction of the second channel 1144 . The insertion hole can penetrate the brush assembly 117 .

[0067] In other embodiments, the matching portion 1164 (for example, the matching portion 1164 may be a block or a plate) has a socket, and the brush assembly 117 has a pin; the pin can be plugged into the socket.

[0068] In some examples, the plug and the socket may be a clearance fit or an interference fit. The plug and the second channel 1144 may be a clearance fit or an interference fit.

[0069] In some embodiments, the connection assembly 116 further includes a connection portion 1163; the connection portion 1163 is located in the dust suction pipe 111; the movable portion 1162 is detachably connected to the connection portion 1163 (for example, by bolts), and the connection portion 1163 is detachably connected to the matching portion 1164 (for example, by bolts). In this way, it is convenient to assemble the connection portion 1163, the movable portion 1162, and the matching portion 1164 in the dust suction pipe 111.

[0070] The connecting portion 1163 may be a structure with connecting capability. For example, the connecting portion 1163 may be a block, a block, a rod, etc. The connecting portion 1163 may be a plate and is located on one side of the connecting member, the moving portion 1162 passes through the first channel 1143 and is connected to the plate, and the matching portion 1164 is connected to the plate.

[0071] In other embodiments, the movable portion 1162 is fixedly connected to the connecting portion 1163 , and the connecting portion 1163 and the matching portion 1164 are detachably connected and fixed.

[0072] In some embodiments, the direction in which the moving portion 1162 drives the matching portion 1164 to move intersects the axial direction of the dust suction tube 111. In this way, the size of the moving portion 1162 in the axial direction of the dust suction tube 111 can be reduced. In addition, the dust suction tube 111 is usually in a vertical state, which is convenient for the user to operate the moving portion 1162 using the opening 1113.

[0073] In some examples, the direction in which the moving portion 1162 drives the matching portion 1164 to move is perpendicular to the axial direction of the dust suction tube 111. The axial direction of the first channel 1143 is perpendicular to the axial direction of the dust suction tube 111. Since the moving portion 1162 moves in the first channel, the axial direction of the moving portion is perpendicular to the axial direction of the dust suction tube 111.

[0074] In some embodiments, the movable portion 1162 is slidably disposed in the first channel 1143; the connecting component 116 also includes an elastic member 1161; the elastic member 1161 is located in the first channel 1143; one end of the elastic member 1161 is connected to the first channel 1143, and the other end of the elastic member 1161 is connected to the movable portion 1162.

[0075] In this way, when a tool is inserted into the first channel 1143 to push the moving part 1162 to slide in the first channel 1143, the moving part 1162 will drive the matching part 1164 to move synchronously; at this time, the moving part 1162 will squeeze the elastic member 1161, so that the elastic force of the elastic member 1161 increases. Then, after removing the tool, the elastic force of the elastic member 1161 can drive the moving part 1162 to reset (i.e., slide in the opposite direction).

[0076] The elastic member 1161 may be an elastic sheet, a spring, etc. In order to reduce the friction between the elastic member 1161, the moving part 1162 and the first channel 1143, the radial dimension of the portion of the first channel 1143 where the elastic member 1161 is disposed is larger; for example, the first channel 1143 includes a first sub-channel 11431, a second sub-channel 11432 and a third sub-channel 11433 that are connected in sequence; the inner diameter of the first sub-channel 11431 is smaller than the inner diameter of the second sub-channel 11432, and the inner diameter of the third sub-channel 11433 is smaller than the inner diameter of the second sub-channel 11432. The elastic member 1161 may be disposed in the second sub-channel 11432.

[0077] In some embodiments, see Figure 6 to Figure 9The mounting member 114 further includes a first limiting portion 1146 and a second limiting portion 1147; the first limiting portion 1146 and the second limiting portion 1147 are spaced apart in the first channel 1143. The moving portion 1162 includes a first sliding bar 11621 and a second sliding bar 11622 connected to each other; the first sliding bar 11621 and the second sliding bar 11622 are both slidably disposed in the first channel 1143, and the second sliding bar 11622 is located between the first limiting portion 1146 and the second limiting portion 1147; the first sliding bar 11621 is connected to the matching portion 1164; the first channel 1143 can expose the second sliding bar 11622.

[0078] In this way, by using a tool to pass through the first channel 1143 to push the second slide bar 11622 to slide in the first channel 1143 between the first limiting portion 1146 and the second limiting portion 1147, the second slide bar 11622 can drive the first slide bar 11621 to move, and the first slide bar 11621 can drive the matching portion 1164 to move. The first limiting portion 1146 and the second limiting portion 1147 limit the second slide bar 11622 in the first channel 1143.

[0079] The first limiting portion 1146 may be a limiting block, a limiting ring, etc.; the second limiting portion 1147 may be a limiting block, a limiting ring, etc. For example, the first limiting portion 1146 and the second limiting portion 1147 may have the same structure (for example, the first limiting portion 1146 and the second limiting portion 1147 may both be limiting rings, limiting blocks, etc.); for another example, the first limiting portion 1146 and the second limiting portion 1147 may have different structures (for example, the first limiting portion 1146 may be a limiting block, and the second limiting portion 1147 may be a limiting ring). Of course, the first limiting portion 1146 may also be a step surface between the first sub-channel 11431 and the second sub-channel 11432, and the second limiting portion 1147 may also be a step surface between the third sub-channel 11433 and the second sub-channel 11432.

[0080] The first slide bar 11621 and the second slide bar 11622 may be fixedly connected, for example, the first slide bar 11621 and the second slide bar 11622 are welded, or the first slide bar 11621 and the second slide bar 11622 are an integral structure. The first slide bar 11621 and the second slide bar 11622 may also be detachably connected, for example, the first slide bar 11621 and the second slide bar 11622 are threadedly connected, clamped, etc.

[0081] In some embodiments, see Figure 6 to Figure 9The first channel 1143 includes a first sub-channel 11431, a second sub-channel 11432 and a third sub-channel 11433 which are connected in sequence; the inner diameter of the first sub-channel 11431 is smaller than the inner diameter of the second sub-channel 11432, and the first stopper 1146 is a step surface between the first sub-channel 11431 and the second sub-channel 11432; the inner diameter of the third sub-channel 11433 is smaller than the inner diameter of the second sub-channel 11432, and the second stopper 1147 is a step surface between the third sub-channel 11433 and the second sub-channel 11432. The first slide bar 11621 is slidably disposed in the first sub-channel 11431; the second slide bar 11622 is slidably disposed in the second sub-channel 11432; the third sub-channel 11433 exposes the second slide bar 11622 in the second sub-channel 11432, and the orthographic projection of the third sub-channel 11433 on the contour surface of the opening 1113 is located within the contour surface of the opening 1113.

[0082] In this way, by using a tool to pass through the third sub-channel 11433 to push the second slide bar 11622 in the second sub-channel 11432 to slide, the second slide bar 11622 can drive the first slide bar 11621 in the first sub-channel 11431 to move, and the first slide bar 11621 can drive the matching portion 1164 to move. The first sub-channel 11431 and the third sub-channel 11433 can limit the second slide bar 11622 in the second sub-channel 11432.

[0083] In some embodiments, see Figure 6 to Figure 9 The mounting member 114 includes a first mounting member 1141 and a second mounting member 1142; the first mounting member 1141 and the second mounting member 1142 are detachably connected; the first mounting member 1141 or the second mounting member 1142 is connected to the dust suction pipe 111; the first mounting member 1141 has a first sub-channel 11431 and a second sub-channel 11432; the second mounting member 1142 has a third sub-channel 11433. In this way, when the first mounting member 1141 and the second mounting member 1142 are disassembled, the connected first slide bar 11621 and the second slide bar 11622 can be taken out from the first sub-channel 11431 and the second sub-channel 11432; so as to facilitate the installation and replacement of the moving part 1162.

[0084] The first mounting member 1141 or the second mounting member 1142 is connected to the dust suction pipe 111; for example, the first mounting member 1141 is connected to the dust suction pipe 111, and the second mounting member 1142 is separated from the dust suction pipe 111; for another example, the second mounting member 1142 is connected to the dust suction pipe 111, and the first mounting member 1141 is separated from the dust suction pipe 111.

[0085] In some examples, the second mounting member 1142 has a mounting groove 1148, the first mounting member 1141 is installed in the mounting groove 1148, and the third sub-channel 11433 is connected to the mounting groove 1148. At this time, the groove wall of the mounting groove 1148 where the third sub-channel 11433 is provided can serve as a step surface between the third sub-channel 11433 and the second sub-channel 11432.

[0086] In some examples, the mounting member 114 is directly connected to the dust suction pipe 111, for example, the mounting member 114 is welded to the dust suction pipe 111. In other examples, the mounting member 114 is indirectly connected to the dust suction pipe 111, for example, the mounting member 114 is movably arranged on the dust suction pipe 111 through the telescopic assembly 112 described below.

[0087] In some embodiments, see Figure 3 and Figure 4 The brush assembly 117 includes a brush holder 1171 and a brush 1172; the brush holder 1171 and the brush 1172 are detachably connected; and the brush holder 1171 is connected to the connecting assembly 116. In this way, the connecting assembly 116 is connected to the brush holder 1171, reducing the risk of damaging the brush 1172, and only the brush 1172 needs to be replaced, and the brush holder 1171 can be reused.

[0088] The brush holder 1171 and the brush 1172 may be connected by bolts, by snaps, or by threads. The brush assembly 117 has a socket, which can be understood as a socket on the side of the brush holder 1171. In some examples, when the mounting member 114 is fixed in the dust suction tube 111, the connecting member 116 connects the brush holder 1171 to the mounting member 114, and the brush 1172 extends out of the second nozzle of the dust suction tube 111. When in use, the brush 1172 does not need to be extended or retracted, and can directly brush away impurities such as solder.

[0089] In some embodiments, see Figure 3 and Figure 4 The dust removal mechanism 11 also includes a telescopic component 112; the telescopic component 112 is arranged outside the dust suction pipe 111; a part of the mounting member 114 is located in the dust suction pipe 111; the other part of the mounting member 114 passes through the opening 1113 and is connected to the telescopic component 112; the telescopic component 112 is used to drive the mounting member 114 to move axially along the dust suction pipe 111 in the opening 1113.

[0090] In this way, the telescopic assembly 112 can drive the mounting member 114 to move in the opening 1113 along the axial direction of the dust suction pipe 111, so that the brush 1172 mechanism on the mounting member 114 can extend out of the second pipe opening of the dust suction pipe 111 or retract into the second pipe opening. The mounting member 114 partially extends out of the opening 1113 to facilitate the connection between the mounting member 114 and the telescopic assembly 112.

[0091] In some examples, the mounting member 114 includes a first mounting member 1141 and a second mounting member 1142, a portion of the first mounting member 1141 is located inside the dust suction pipe 111, and another portion is located outside the dust suction pipe 111; the second mounting member 1142 is detachably connected to the first mounting member 1141 outside the dust suction pipe 111; and the second mounting member 1142 is connected to the telescopic assembly 112. Thus, the telescopic assembly 112 drives the second mounting member 1142 to move along the axial direction of the dust suction pipe 111, and the second mounting member 1142 drives the first mounting member 1141 to move in the opening 1113; the first mounting member 1141 drives the brush assembly 117 to extend out of the second pipe opening of the dust suction pipe 111 or to retract into the second pipe opening. For example, the dust removal mechanism 11 also includes a sliding assembly 115, which is arranged between the dust suction pipe 111 and the second mounting member 1142; the sliding assembly 115 can make the movement of the second mounting member 1142 more stable. The sliding assembly 115 may include, for example, a slide rail and a slider, wherein the slide rail is disposed on the dust suction pipe 111, the slider is disposed on the second mounting member 1142, and the slider is slidably disposed in the slide rail. For example, the dust removal mechanism 11 also includes a connector 113, through which the telescopic assembly 112 is connected to the second mounting member 1142; the connector 113 facilitates the connection between the telescopic assembly 112 and the second mounting member 1142. The connector 113 may be a floating head, a flange, etc. The telescopic assembly 112 may be an electric push rod, a cylinder, etc.
