Description

Technical Field

[0001] The present application relates to a battery production device, and more particularly to a dust removal device and a battery production system. Background Art

[0002] Dust such as dust and metal debris will adhere to the surface of the base material of the current collector for producing batteries, such as copper foil and aluminum foil. During the process of preparing the battery, it is necessary to clean the surface of the base material to meet the production process requirements. Currently, the base material is cleaned by a brush, but the problem is that it is easy to cause scratches on the surface of the base material, and some dust will also adhere to the brush, causing secondary pollution to the base material during the cleaning process. Utility Model Content

[0003] In view of the above problems, the present application provides a dust removal device and a battery production system, which can improve the situation of scratches and secondary pollution on the surface of the base material.

[0004] In a first aspect, the present application provides a dust removal device, including:

[0005] A dust removal assembly, the dust removal assembly includes two dust removal components arranged oppositely. Among them, a dust removal channel is formed between the two dust removal components, and the dust removal channel is used for the workpiece to be dust-removed to pass through. The dust removal component is used to blow off and adsorb the dust on the surface of the workpiece to be dust-removed.

[0006] The workpiece to be dust-removed can be the base material of the current collector for producing batteries. During the dust removal process, the base material passes through the dust removal channel, and the dust removal component removes the dust on both sides of the base material by blowing and suction. Compared with the method of using a brush to remove dust, it can reduce scratches on the base material, and during dust removal, the blown-off dust will be sucked away, thereby reducing the accumulation of dust in the dust removal channel to reduce secondary pollution of the base material.

[0007] In some embodiments, an air blowing channel is formed inside the dust removal component, and an air inlet is provided outside the dust removal component. The air inlet is communicated with the air blowing channel, and the air blowing channel penetrates the surface of the dust removal component facing the dust removal channel and forms an air blowing port, and the air blowing port is used to blow off the dust on the surface of the workpiece to be dust-removed.

[0008] Positive pressure air is introduced into the air inlet of the air blowing channel, so that the air blowing port can purge the dust on the surface of the base material to detach the dust from the surface of the base material, achieving the purpose of cleaning the base material.

[0009] In some embodiments, the number of air inlets is multiple, and the multiple air inlets are arranged at intervals along a first direction, and the first direction intersects the interval direction of the two dust removal components and the passing direction of the dust removal channel respectively.

[0010] When the width of the substrate is large, the size of the blowing channel along the first direction is large. If only one air inlet is provided, the pressure distribution in the blowing channel may be uneven, resulting in large differences in the air flow speeds ejected from different positions of the blowing port, resulting in different dust removal effects. Therefore, providing multiple air inlets can make the pressure distribution in the blowing channel more uniform during dust removal, thereby improving the dust removal effect.

[0011] In some embodiments, a dust suction channel is formed inside the dust removal component, and a dust suction channel is provided on at least one side of the blowing channel along the passing direction. The dust suction channel and the blowing channel are spaced apart. The dust suction channel runs through the surface of the dust removal component facing the dust removal channel and forms an air suction port, which is used to absorb dust. An exhaust port is provided on the outer surface of the dust removal component, and the exhaust port is connected to the dust suction channel.

[0012] By applying negative pressure to the exhaust port, dust near the part to be dusted is sucked into the dust suction channel, so that the dust can be blown off the surface of the part to be dusted by the air outlet and then sucked away, thereby reducing the accumulation of dust in the dust removal channel during the dust removal process, thereby improving the cleanliness of the surface of the part to be dusted.

[0013] In some embodiments, in the same dust removal component, the blowing channel includes a first channel section, the first channel section passes through the surface of the dust removal component facing the dust removal channel to form an air blowing port, the first channel section includes a first wall and a second wall arranged opposite to each other, the end of the dust removal component facing the dust removal channel is the first end, and the other end of the dust removal component away from the dust removal channel is the second end, along the direction from the first end to the second end, the minimum spacing between the first wall and the air intake port along the passing direction shows an increasing trend, and the minimum spacing between the second wall and the air intake port along the passing direction shows an increasing trend.

[0014] Thus, most of the dust blown off from the dust-removing parts by the air port can fall into the suction area of ​​the air intake port, so that the dust can be sucked out through the air intake port to reduce the secondary contamination of the dust-removing parts, thereby improving the cleanliness of the dust-removing parts.

[0015] In some embodiments, the dust removal assembly also includes a connecting component, the connecting component includes a slide module, the first dust removal component is provided with a slide module at at least one end along the first direction, the slide module includes a slide body and two sliders, the slide body is respectively driven and connected to the two sliders, the slide body is used to drive the two sliders to move toward each other or away from each other along the spacing direction of the two dust removal components, the two sliders are connected to different dust removal components, and the first direction, the spacing direction of the two dust removal components and the passing direction of the dust removal channel intersect with each other.

[0016] The dust removal effects are different when the blowing distances of the dust removal components on both sides of the dust removal channel are different. The slide table module drives the two sliders to move towards or away from each other, so as to be able to adjust the distance between the dust removal components on both sides of the dust removal channel, so that the dust removal components on both sides of the dust removal channel respectively have a better dust removal distance from the component to be dusted, thereby achieving a better dust removal effect.

[0017] In some embodiments, the dust removal device further includes a support assembly. At least one end of the dust removal assembly in the first direction is connected to the support assembly. The support assembly includes an adjusting component and a support member. The support member is connected to the dust removal assembly through the adjusting component. The adjusting component has a first axis that rotates relative to the support member. The extending direction of the first axis is the same as the first direction. The adjusting component is used to adjust the position of the dust removal assembly rotating around the first axis relative to the support member. The first direction, the interval direction of the two dust removal components, and the passing direction of the dust removal channel intersect pairwise.

[0018] When the component to be dusted passes through the dust removal channel, different positions of the dust removal assembly rotating around the first axis relative to the support assembly will affect the blowing and suction effects, thereby affecting the dust removal effect. By adjusting the position of the dust removal assembly rotating around the first axis relative to the support assembly, the blowing angle and suction angle of the dust removal assembly can be changed to dust the component to be dusted at a preset position, thereby achieving a better dust removal effect.

[0019] In some embodiments, the adjusting component includes a first connecting member, a first locking member, and a connecting shaft. The connecting shaft is connected to the dust removal assembly. A part of the connecting shaft is inserted into the first connecting member. The first locking member is connected to the first connecting member. The first locking member has an unlocked state that enables the connecting shaft to rotate relative to the first connecting member, and a locked state that enables the connecting shaft and the first connecting member to be relatively fixed. The axis of the connecting shaft forms the first axis.

[0020] Thus, by unlocking and locking the first locking member, the rotation and fixation of the connecting shaft are realized, so as to realize the adjustment and fixation of the position of the dust removal assembly rotating around the first axis relative to the support member, so as to dust the component to be dusted at a preset position, thereby achieving a better dust removal effect.

[0021] In some embodiments, the first connecting member includes a first connecting piece and a second connecting piece. The first connecting piece and the second connecting piece are connected through the first locking member. The first connecting piece and the second connecting piece jointly enclose a plugging hole. Along the radial direction of the plugging hole, the first connecting piece and the second connecting piece are arranged with a gap. The first locking member is configured to be able to change the gap.

[0022] By adjusting the first locking member, the gap between the first connecting member and the second connecting member can be changed, and the extrusion force on the connecting shaft can be changed, thereby realizing the loosening and locking of the connecting shaft, realizing the rotation of the connecting shaft relative to the first connecting member, and further realizing the adjustability of the rotation angle of the dust removal assembly relative to the support member.

[0023] In some embodiments, the dust removal device further includes a support assembly. At least one end of the dust removal assembly in the first direction is connected to the support assembly. The support assembly includes an adjustment member and a support member. The support member is connected to the dust removal assembly through the adjustment member. The adjustment member is used to adjust the position of the dust removal assembly relative to the support member along the interval direction between the two dust removal members. The first direction, the interval direction between the two dust removal members, and the passing direction of the dust removal channel intersect pairwise.

[0024] During dust removal, when the distances from the first dust removal member and the second dust removal member to the member to be dusted are quite different, it is possible that one of the dust removal members on both sides of the dust removal channel has a good dust removal effect, while the other has a poor dust removal effect. To improve this situation, the adjustment member is used to adjust the movement of the dust removal assembly along the interval direction between the two dust removal members, so that the dust removal members on both sides of the dust removal channel move synchronously along the interval direction between the two dust removal members, making the distances from the dust removal members on both sides of the dust removal channel to the member to be dusted substantially equal, thereby making the dust removal effects of the dust removal members on both sides of the dust removal channel substantially the same, and thus improving the consistency of the cleanliness of the two sides of the member to be dusted.

[0025] In some embodiments, the adjustment member includes a first connecting member and a second locking member. The first connecting member is connected to the dust removal assembly. A long slot hole is provided on the surface of one of the support member and the first connecting member facing the dust removal assembly. The length direction of the long slot hole is the same as the interval direction between the two dust removal members. The support member is connected to the first connecting member through the second locking member. One end of the second locking member passes through the long slot hole, and the position of the second locking member in the long slot hole along the interval direction between the two dust removal members is adjustable.

[0026] By unlocking the second locking member, the second locking member can move in the long slot hole to change the position of the dust removal assembly relative to the support member along the interval direction between the two dust removal members, thereby adjusting the distances from the dust removal members on both sides of the dust removal channel to the member to be dusted respectively, making the two distances substantially equal, so as to improve the consistency of the cleanliness of the two sides of the member to be dusted.

[0027] In some embodiments, the first connecting member is slidably connected to the support member along the spacing direction of the two dust removal components. The adjusting component further includes an adjusting member, which includes a rod portion. A part of the rod portion is rotatably connected to the support member. The surface of the first connecting member along the spacing direction of the two dust removal components is provided with a threaded hole. The axial direction of the threaded hole and the extending direction of the axis of the rod portion relative to the rotation of the support member are respectively the same as the spacing direction of the two dust removal components, and at least a part of the rod portion is threadedly connected to the threaded hole.

[0028] During the adjustment process, in order to reduce the relative swing between the first connecting member and the support member, the first connecting member is slidably connected to the support member along the spacing direction of the two dust removal components, which can play a guiding role during the adjustment process. At the same time, through the threaded connection between the adjusting member and the threaded hole, the distances from the dust removal components on both sides of the dust removal channel to the piece to be dusted can be accurately adjusted.

[0029] In some embodiments, the adjusting component includes a first connecting member, a first locking member, and a connecting shaft. The connecting shaft is connected to the dust removal assembly. A part of the connecting shaft is inserted into the first connecting member. The extending direction of the axis of the connecting shaft is the same as the first direction. The first locking member is connected to the first connecting member, and the first locking member has an unlocked state that enables the connecting shaft to rotate relative to the first connecting member, and a locked state that enables the connecting shaft and the first connecting member to be relatively fixed. A long slot hole is provided on the surface of one of the first connecting member and the support member facing the dust removal assembly.

[0030] On the basis that the second locking member adjusts the distances from the dust removal components on both sides of the dust removal channel to the piece to be dusted respectively, by adjusting the first locking member, the position where the dust removal assembly rotates relative to the support member around the first axis can be realized, so that the dust removal assembly dusts the piece to be dusted at a preset position, thereby achieving a better dust removal effect.

[0031] In a second aspect, the present application provides a battery production system, including a conveying device and the dust removal device of the first aspect. The conveying device includes a first over-roller and a second over-roller. The first over-roller and the second over-roller are located on both sides of the dust removal device along the passing direction. The first over-roller and the second over-roller are respectively used to convey the piece to be dusted through the dust removal channel, and the piece to be dusted is the base material of the current collector for producing a battery.

[0032] Since the battery production system includes all the technical features of the dust removal device of the first aspect, the effects are the same as those described above and will not be elaborated here.

[0033] The above description is only an overview of the technical solution of the present application.

Compared with the method of using a brush to remove dust, it can reduce the scratches on the base material, and when removing dust, the blown-off dust will be sucked away, so as to reduce the accumulation of dust in the dust removal channel and reduce the secondary pollution of the base material.

[0066] The dust removal device of the present application can be used for dust removal of coils or sheets. The coils or sheets can be made of metal or non-metal materials. For example, the base materials of the current collectors for manufacturing batteries, or plastic films used in food and chemical industries, etc.

[0067] For the convenience of description in the following embodiments, please refer to Figures 1-10 , and take a dust removal device 1000 of some embodiments of the present application as an example for description.

[0068] The dust removal assembly 100 includes two dust removal components 110 arranged oppositely. Among them, a dust removal channel 140 is formed between the two dust removal components 110. The dust removal channel 140 is used for the object to be dusted 300 to pass through, and the dust removal component 110 is used to blow off and adsorb the dust on the surface of the object to be dusted 300.

[0069] Optionally, the number of the dust removal components 110 can be two or more, that is, the number of the dust removal components 110 on either side of the dust removal channel 140 can be one or more.

[0070] Optionally, the interval direction X of the two dust removal components 110 and the passing direction Z of the dust removal channel 140 can be perpendicular or not perpendicular.

[0071] Exemplarily, the dust removal component 110 includes a plurality of air nozzles and a dust collection hood. The air nozzles are located at the dust collection opening of the dust collection hood. Air is blown to the object to be dusted 300 through the air nozzles to make the dust fall into the dust collection opening, and then a negative pressure pipeline is connected to the dust collection hood to collect the dust, so as to realize the dust removal of one side surface of the object to be dusted 300.

[0072] Optionally, the dust removal assembly 100 further includes a connecting component 130. The dust removal component 110 is provided with a connecting component 130 at at least one end along the first direction Y. The connection between the dust removal component 110 and the connecting component 130 includes, but is not limited to, bolt connection, welding, snap connection, etc. Optionally, the dust removal channel 140 can be a channel formed by enclosing with three side frames, or can also be a channel formed by enclosing with four side frames. For example, the dust removal component 110 is provided with connecting components 130 at both ends along the first direction Y, that is, the dust removal channel 140 is a channel formed by enclosing with four side frames. The dust removal components 110 on both sides of the dust removal channel 140 form two first side frames arranged at intervals along the interval direction X of the two dust removal components, and the connecting components 130 at both ends of the dust removal component 110 along the first direction Y form two second side frames arranged at intervals along the first direction Y. In other examples, the connecting component 130 can also not be provided, which is specifically determined according to the usage scenario.

[0073] The passing direction Z of the dust removal channel 140 refers to the direction from the channel opening at one end of the dust removal channel 140 to the channel opening at the other end, that is, the direction in which the piece to be dust removed 300 passes through the dust removal channel 140.

[0074] The piece to be dust removed 300 can be the base material of the current collector for producing batteries. During the dust removal process, the base material passes through the dust removal channel 140.

[0075] The dust removal components 110 on both sides of the dust removal channel 140 remove the dust on the surface of the base material by blowing and suction. Compared with the method of removing dust with a brush, it can reduce the scratching of the base material, and when removing dust, the blown-off dust will be sucked away, so as to reduce the accumulation of dust in the dust removal channel 140 and reduce the secondary pollution of the base material.

[0076] In some embodiments, please refer to Figure 4 , an air blowing channel 1111 is formed inside the dust removal component 110, an air inlet 1113 is provided outside the dust removal component 110, the air inlet 1113 is communicated with the air blowing channel 1111, the air blowing channel 1111 penetrates through the surface of the dust removal component 110 facing the dust removal channel 140, and an air blowing port 1112 is formed. The air blowing port 1112 is used to blow off the dust on the surface of the piece to be dust removed 300.

[0077] Optionally, the dust removal component 110 includes a first dust removal pipe. Both ends of the first dust removal pipe are blocked, an air blowing channel 1111 is formed inside the first dust removal pipe, and the air blowing channel 1111 penetrates through the surface of the first dust removal pipe facing the dust removal channel 140 and forms an air blowing port 1112.

[0078] Optionally, the air blowing port 1112 can be a strip-shaped port extending along the first direction Y.

[0079] Optionally, the dust removal component 110 further includes a pneumatic joint, and the air inlet 1113 is hermetically connected to the pneumatic joint to facilitate the connection between the external air pipe and the air inlet 1113.

[0080] Optionally, the air inlet 1113 is provided on the surface of the first dust removal pipe facing away from the dust removal channel 140, or can be provided on one side of the first dust removal pipe along the passing direction Z.

[0081] Positive pressure air is introduced into the air inlet 1113 of the blowing channel 1111, so that the blowing port 1112 can blow the dust on the surface of the substrate, so as to separate the dust from the surface of the substrate and achieve the purpose of cleaning the substrate.

[0082] In some embodiments, please refer to Figure 1 , the number of the air inlets 1113 is multiple, and the multiple air inlets 1113 are arranged at intervals along the first direction Y. The first direction Y, the interval direction X between the two dust removal components, and the passing direction Z of the dust removal channel 140 intersect pairwise.

[0083] For the convenience of description, the first direction Y, the interval direction X between the two dust removal components, and the passing direction Z in the following embodiments intersect pairwise.

[0084] The first direction Y, the interval direction X between the two dust removal components, and the passing direction Z can be perpendicular to each other pairwise, or can be non-perpendicular to each other pairwise.

[0085] When the width of the substrate is relatively large, the size of the blowing channel 1111 along the first direction Y is relatively large. If only one air inlet 1113 is provided, the pressure distribution in the blowing channel 1111 may be uneven, resulting in a large difference in the air flow velocity ejected from different positions of the blowing port 1112 and generating different dust removal effects. Therefore, setting multiple air inlets 1113 can make the pressure distribution in the blowing channel 1111 more uniform during dust removal, so as to improve the dust removal effect.

[0086] In some embodiments, please refer to Figure 4 , a dust suction channel 1121 is formed inside the dust removal component 110. The dust suction channel 1121 is provided on at least one side of the blowing channel 1111 along the passing direction Z. The dust suction channel 1121 is arranged at an interval from the blowing channel 1111. The dust suction channel 1121 penetrates through the surface of the dust removal component 110 facing the dust removal channel 140 and forms a suction port 1122. The suction port 1122 is used to suck dust. An exhaust port 11661 is provided on the outer surface of the dust removal component 110, and the exhaust port 11661 is communicated with the dust suction channel 1121.

[0087] Optionally, the suction port 1122 can be a strip-shaped port extending along the first direction Y.

[0088] Exemplarily, please refer to Figure 2 and Figure 4, the dust removal component 110 further includes a first blowing pipe 111, a first dust suction pipe 112, a first gasket 113 and a first plugging member 114. The first blowing pipe 111 and the first dust suction pipe 112 are arranged along the passing direction Z, and a first plugging member 114 is provided at the same end of the two along the first direction Y. The first plugging member 114 is respectively connected to the first blowing pipe 111 and the first dust suction pipe 112. A first gasket 113 is provided between the first blowing pipe 111 and the first dust suction pipe 112 and the first plugging member 114. Through the first gasket 113 and the first plugging member 114, the two ends of the first blowing pipe 111 and the first dust suction pipe 112 are plugged. The cavity inside the first blowing pipe 111 serves as the blowing channel 1111, and the internal cavity of the first dust suction pipe 112 serves as the dust suction channel 1121. The first blowing pipe 111 and the first dust suction pipe 112 can be an integral structure or a split structure. In other examples, the first gasket 113 can also be omitted, and the same end of the two is welded by a first plugging member 114 to plug the internal cavity of the first blowing pipe 111 and the internal cavity of the first dust suction pipe 112 to form the blowing channel 1111 and the dust suction channel 1121. Further optionally, the dust removal component 110 further includes two first partition members 115. The two first partition members 115 are located in the cavity of the first blowing pipe 111 and are spaced along the passing direction Z. The two first partition members 115 jointly define a part of the blowing channel 1111, and a part of the blowing channel 1111 communicates with the first channel section 11111.

[0089] Optionally, the dust removal component 110 further includes a first air suction pipeline 116, and the first air suction pipeline 116 communicates with the exhaust port 11661.

[0090] Exemplarily, please refer to Figure 2, the first air suction pipeline 116 includes two branch pipes 1161, a second sealing gasket 1162, a first hose 1163, a tee 1164, a second hose 1165 and a pipe joint 1166. Among them, one end of each of the two branch pipes 1161 is connected to the dust suction channel 1121 respectively, and is sealed and connected to the first dust suction pipe 112 through the second sealing gasket 1162. The other end of each of the two branch pipes 1161 is connected to the first hose 1163, which can be sleeved on the other end of the minute pipe and fixed by a clamp. The two first hoses 1163 are connected to the two ports of the tee 1164, and the other port of the tee 1164 is connected to the pipe joint 1166 through the second hose 1165. In other examples, the first hose 1163 and the second hose 1165 can be replaced by metal pipes or plastic pipes, and the two ends of the first hose 1163 and the two ends of the second hose 1165 can be connected to the corresponding pipeline or joint by welding or bonding at the connection position. In other examples, the first air suction pipeline 116 may be a tube, specifically a hose or a rigid tube. The end of the first air suction pipeline 116 away from the first dust suction pipe 112 serves as the air suction port 1122, that is, the exhaust end of the pipe joint 1166 serves as the air suction port 1122. In other examples, the first air suction pipeline 116 may not be provided.

[0091] By applying negative pressure to the exhaust port 11661, dust near the part to be dusted 300 is sucked into the dust suction channel 1121, so that the dust is blown off the surface of the part to be dusted 300 by the air outlet 1112 and then sucked away, thereby reducing the accumulation of dust in the dust removal channel 140 during the dust removal process, thereby improving the cleanliness of the surface of the part to be dusted 300.

[0092] In some embodiments, please refer to Figures 4-6 In the same dust removal component 110, the blowing channel 1111 includes a first channel section 11111, the first channel section 11111 penetrates the surface of the dust removal component 110 facing the dust removal channel 140 and forms an air blowing port 1112, the first channel section 11111 includes a first wall 111111 and a second wall 111112 arranged opposite to each other, the end of the dust removal component 110 facing the dust removal channel 140 is the first end, and the other end of the dust removal component 110 away from the dust removal channel 140 is the second end, along the direction from the first end to the second end, the minimum spacing between the first wall 111111 and the air intake port 1122 along the passing direction Z shows an increasing trend, and the minimum spacing between the second wall 111112 and the air intake port 1122 along the passing direction Z of the dust removal channel 140 shows an increasing trend.

[0093] In this example, the dust removal components 110 that appear all refer to the same component.

[0094] The minimum distance between the first wall surface 111111 and the air suction port 1122 in the direction Z refers to the distance from the edge of the air suction port 1122 with the minimum distance from the first wall surface 111111 to the first wall surface 111111 along the passing direction Z of the dust removal channel 140.

[0095] The minimum distance between the second wall surface 111112 and the air suction port 1122 refers to the distance from the edge of the air suction port 1122 with the minimum distance from the first wall surface 111111 to the second wall surface 111112 along the passing direction Z of the dust removal channel 140.

[0096] Thus, most of the dust blown off from the part to be dust-removed 300 by the air blowing port 1112 can fall into the suction area of the air suction port 1122, and the dust is sucked through the air suction port 1122, so as to reduce the secondary pollution of the dust to the part to be dust-removed 300, thereby improving the cleanliness of the part to be dust-removed 300.

[0097] In some embodiments, please refer to Figures 7-8 , dust suction channels 1121 are respectively arranged on both sides of the air blowing channel 1111 along the passing direction Z. Each dust suction channel 1121 penetrates the surface of the dust removal component 110 facing the dust removal channel 140 and forms an air suction port 1122.

[0098] Exemplarily, first dust suction pipes 112 are respectively arranged on both sides of the first air blowing pipe 111 along the passing direction Z. An air suction port 1122 is formed on the surface of each first dust suction pipe 112 facing the dust removal channel 140.

[0099] When the blowing direction of the air blowing port 1112 is perpendicular to the passing direction Z of the part to be dust-removed 300, the dust will move along both sides of the passing direction Z. Dust suction channels 1121 are respectively arranged on both sides of the air blowing channel 1111 along the passing direction Z, and the air suction port 1122 of each dust suction channel 1121 can suck the dust moving along both sides of the passing direction Z, so as to reduce the secondary pollution of the dust to the part to be dust-removed 300, thereby improving the cleanliness of the part to be dust-removed 300.

[0100] Thus, sucking air into the first air suction pipeline 116 can suck the dust, reduce the accumulation of dust in the dust suction channel 1121, thereby reducing the blockage of the dust suction channel 1121, and facilitating the connection of the air suction port 1122 with the external negative pressure pipeline through the first air suction pipeline 116.

[0101] In some embodiments, please refer to Figure 2 and Figure 9, the dust removal assembly 100 further includes a connecting component 130. The connecting component 130 includes a slide module 131. At least one end of the dust removal component 110 along the first direction Y is provided with a slide module 131. The slide module 131 includes a slide body 1311 and two sliders 1312. The slide body 1311 is respectively drivingly connected to the two sliders 1312. The slide body 1311 is used to drive the two sliders 1312 to move towards each other or away from each other along the interval direction X between the two dust removal components. The two sliders 1312 are connected to different dust removal components 110.

[0102] Optionally, the slide module 131 can be a pneumatic finger with two claws, a pneumatic slide table or an electric slide table having two sliders 1312.

[0103] Exemplarily, the slide body 1311 includes a seat body, a guide rail, a lead screw, two nuts and a motor. The seat body is rotatably connected with the lead screw. The axial direction of the lead screw is the same as the interval direction X between the two dust removal components. The outer peripheral surface of the lead screw has two thread segments, and the rotation directions of the two thread segments are opposite. The two nuts are respectively threadedly connected to the two thread segments, and the two nuts are respectively connected to the two sliders 1312. One end of the lead screw is drivingly connected to the motor. By driving the lead screw to rotate by the motor, the movement of the two sliders 1312 towards each other or away from each other is realized.

[0104] The dust removal effects produced by different blowing distances of the dust removal components 110 on both sides of the dust removal channel 140 are different. The slide module 131 drives the two sliders 1312 to move towards each other or away from each other, so as to be able to adjust the distance between the dust removal components 110 on both sides of the dust removal channel 140, so that the dust removal components 110 on both sides of the dust removal channel 140 respectively have a better dust removal distance from the object to be dusted 300, thereby achieving a better dust removal effect.

[0105] In some embodiments, please refer to Figure 2 and Figure 3 , the dust removal device 1000 further includes a support assembly 200. At least one end of the dust removal assembly 100 along the first direction Y is connected with a support assembly 200. The support assembly 200 includes an adjusting component and a support member 220. The support member 220 is connected to the dust removal assembly 100 through the adjusting component. The adjusting component has a first axis that rotates relative to the support member 220. The extending direction of the first axis is the same as the first direction Y. The adjusting component is used to adjust the position of the dust removal assembly 100 relative to the support member 220 around the first axis.

[0106] The support member 220 can be a single piece or an integral structure formed by connecting multiple pieces. For example, the support member 220 includes a first support piece 221 and a second support piece 222, and the first support piece 221 and the second support piece 222 are connected. The connection between the two can be, but is not limited to, screw connection, welding, riveting, or integral molding, etc.

[0107] When the part 300 to be dust-removed passes through the dust-removing channel 140, different positions of the dust-removing assembly 100 rotating relative to the support assembly 200 around the first axis will affect the blowing and suction effects, thereby affecting the dust-removing effect. By adjusting the position of the dust-removing assembly 100 rotating relative to the support assembly 200 around the first axis, the blowing angle and suction angle of the dust-removing assembly 100 can be changed to dust the part 300 to be dust-removed at a preset position, so as to achieve a better dust-removing effect.

[0108] In some embodiments, please refer to Figure 2 and Figure 3 , the adjusting member includes a first connecting member 211, a first locking member 212, and a connecting shaft 213. The connecting shaft 213 is connected to the dust-removing assembly 100. Part of the connecting shaft 213 is inserted into the first connecting member 211.

The axis of the connecting shaft 213 forms the first axis.

[0109] Optionally, the connecting member 130 further includes a first sub-connecting member 132 and a second sub-connecting member 133.

The second sub-connecting member 133 is located on the side of the first sub-connecting member 132 away from the sliding table module 131 and is connected to the first sub-connecting member 130. The connection between the first sub-connecting member 130 and the second sub-connecting member 133 includes, but is not limited to, screw connection, clamping connection, welding, or integral molding, etc. The connection between the first sub-connecting member 132 and the sliding table module 131 can be, but is not limited to, screw connection or welding, etc. The connecting shaft 213 is connected to the second sub-connecting member 133. The connection between the connecting shaft 213 and the second sub-connecting member 133 includes, but is not limited to, welding, clamping connection, or screw connection, etc. Exemplarily, the surface of the second sub-connecting member 133 away from the sliding table module 131 is provided with a mounting hole, the connecting shaft 213 is inserted into the mounting hole, the second sub-connecting member 133 is provided with a threaded connection hole, and a fastening screw is threadedly connected to the threaded connection port. The end of the fastening screw abuts against the connecting shaft 213.

[0110] The first connecting member 211 can be a single piece or an integral structure formed by connecting multiple pieces.

[0111] Exemplarily, the first connecting member 211 has a protrusion on the side facing the dust removal assembly 100, and the protrusion is plugged into the connecting shaft 213. The end of the connecting shaft 213 facing away from the dust removal assembly 100 may be provided with a socket, and the protrusion is inserted into the socket. The first locking member 212 includes a set screw, and the outer peripheral surface of the connecting shaft 213 is provided with a threaded hole, and the threaded hole passes through the socket along the radial direction of the connecting shaft 213. The set screw is threadedly connected to the threaded hole, and the end of the set thread abuts against the protrusion. When the set screw is loosened, the connecting shaft 213 is rotated relative to the protrusion, so that the dust removal assembly 100 is rotated relative to the support member 220 around the first axis. After rotating to a predetermined position, the set screw is locked to fix the connecting shaft 213 and the protrusion. In another example, the first connecting member 211 may be provided with a plug-in hole on the side facing the dust removal assembly 100, and a portion of the connecting shaft 213 may be inserted into the plug-in hole. A threaded hole may be provided on the outer surface of the first connecting member 211, and the threaded hole may pass through the plug-in hole in a radial direction. A portion of the connecting shaft 213 may be plugged into the plug-in hole, and a fixing screw may be threadedly connected to the threaded hole, and an end portion of the fixing screw may be able to abut against the outer peripheral surface of the connecting shaft 213.

[0112] Therefore, by unlocking and locking the first locking member 212, the rotation and fixation of the connecting shaft 213 are achieved, thereby achieving the adjustment and fixation of the position of the dust removal assembly 100 rotating around the first axis relative to the support member 220, so as to remove dust from the dust removal member 300 at a preset position, thereby achieving a better dust removal effect.

[0113] In some embodiments, please refer to Figure 2 and Figure 3 The first connecting member 211 includes a first connecting member 2111 and a second connecting member 2112, and the first connecting member 2111 and the second connecting member 2112 are connected by a first locking member 212, and the first connecting member 2111 and the second connecting member 2112 are together surrounded by a plug-in hole, and along the radial direction of the plug-in hole, the first connecting member 2111 and the second connecting member 2112 are arranged with a gap, and the first locking member 212 is configured to be able to change the gap.

[0114] Optionally, the first connecting member 2111 and the second connecting member 2112 may be an integral structure or a separate structure.

[0115] Exemplarily, the first locking member 212 includes a screw. The first connecting member 2111 is provided with a connecting hole, and the second connecting member 2112 is provided with a threaded hole. The screw passes through the connecting hole and is threadedly connected to the threaded hole. By using the fastening force of the screw, the size of the gap can be changed, that is, the clamping force of the first connecting member 2111 and the second connecting member 2112 on the connecting shaft 213 can be changed, so as to realize the loosening and fixing of the connecting shaft 213. In other examples, the first locking member 212 further includes a nut. The threaded hole is replaced with a bolt hole. The end of the screw passes through the connecting hole and the bolt hole, and is threadedly connected with a nut.

[0116] By changing the distance between the first wall body and the second wall body, the extrusion force of the connecting shaft 213 can be changed, so as to realize the loosening and locking of the connecting shaft 213, so as to realize the rotation of the connecting shaft 213 relative to the first connecting member 2111, and further realize the adjustability of the rotation angle of the dust removal assembly 100 relative to the support member 220.

[0117] In some embodiments, please refer to Figure 2 and Figure 3 , the dust removal device 1000 further includes a support assembly 200.

The adjusting member is used to adjust the position of the dust removal assembly 100 relative to the support member 220 along the interval direction X of the two dust removal members.

[0118] During dust removal, when the distances from the dust removal members 110 on both sides of the dust removal channel 140 to the piece to be dusted 300 are quite different, it is possible that one of the dust removal members 110 on both sides of the dust removal channel 140 has a good dust removal effect and the other has a poor dust removal effect. To improve this situation, the dust removal assembly 100 is adjusted to move along the interval direction X of the two dust removal members through the adjusting member, so that the dust removal members 110 on both sides of the dust removal channel 140 move synchronously along the interval direction X of the two dust removal members, so that the distances from the dust removal members 110 on both sides of the dust removal channel 140 to the piece to be dusted 300 are substantially equal, so that the dust removal effects of the dust removal members 110 on both sides of the dust removal channel 140 are substantially the same, so as to improve the consistency of the cleanliness of the two sides of the piece to be dusted 300.

[0119] In some embodiments, please refer to Figure 2 and Figure 3The adjusting component includes a first connecting member 211 and a second locking member 214.

[0129] The specific structure of the connection between the first connecting member 211 and the connecting shaft 213 may be the same as the structures listed in the above embodiments, and will not be elaborated in detail here.

[0130] On the basis that the second locking member 214 adjusts the distances between the dust removal components 110 on both sides of the dust removal channel 140 to the workpiece to be dusted 300 respectively, by adjusting the first locking member 212, the position where the dust removal assembly 100 rotates relative to the support member 220 around the first axis can be realized, so that the dust removal assembly 100 dusts the workpiece to be dusted 300 at a preset position, thereby achieving a better dust removal effect.
