However, dust easily accumulates on the tray, and excessive dust will seriously affect the battery quality and increase the product defect rate. Traditional dust removal devices have low dust removal efficiency, poor dust movement during the dust removal process, and dust accumulation problems, resulting in poor dust removal effect and making them unsuitable for the dust removal needs of high-precision instruments.

[0022] In related technologies, the battery manufacturing process requires the transport of batteries through a conveying mechanism. To improve the stability of the batteries during transport, a tray is set on the conveying mechanism to place the batteries on the tray. However, dust easily accumulates on the tray, and excessive dust will seriously affect the quality of the batteries and increase the product defect rate. Traditional dust removal devices have their suction ports located at the top, creating an upward airflow around the stage. However, the dust on the stage is already adsorbed (by electrostatic or negative pressure) and cannot move with the upward airflow. This results in poor dust mobility and dust accumulation, making them unsuitable for the dust removal needs of high-precision instruments.

[0023] The following is combined with Figures 1 to 5 This describes an embodiment of the present application.

[0024] According to embodiments of this application, a dust removal device is provided, such as... Figure 1 , Figure 2 and Figure 4 As shown, it includes: a support 1, a conveying mechanism 2, a dust hood 3, a driving mechanism 4, and an exhaust mechanism 8. Specifically, the conveying mechanism 2 is mounted on the support 1 and has a platform 9 on it. The conveying mechanism 2 can move along a first direction. The dust hood 3 is slidably mounted on the support 1 and has a cavity 301 inside. The side wall of the dust hood 3 has an inlet / outlet 302 and an exhaust port 304 that communicate with the cavity 301. During the process of the dust hood 3 sliding from the first position to the second position, the platform 9 enters the cavity 301 through the inlet / outlet 302. The driving mechanism 4 is connected to the dust hood 3 and is suitable for driving the dust hood 3 to slide between the first position and the second position. The exhaust end of the exhaust mechanism 8 is connected to the exhaust port 304.

[0025] In this embodiment, such as Figure 1 , Figure 2 and Figure 4 As shown, the conveying mechanism 2 drives the platform 9 to move. The platform 9 is used to place batteries, and the conveying mechanism 2 transports the batteries through the platform 9. However, before placing the batteries on the platform 9, it is necessary to clean the platform 9 to remove dust without affecting the conveying mechanism 2's transport of the batteries. During the conveying process, when the platform 9 is transported to the dust removal station, the conveying mechanism 2 pauses, and the drive mechanism 4 drives the dust removal hood 3 to slide on the support 1 and move from the first position to the second position. The platform 9 passes through the inlet and outlet 302 and enters the cavity 301. The suction mechanism 8 starts working to suction air from the cavity 301. Air enters the cavity 301 from the inlet and outlet 302 and exits from the suction hole 304, forming an airflow in the cavity 301. The airflow direction is parallel to the platform 9, which can create a low-pressure area above the platform 9, making it easier to blow dust away from the platform 9, increasing dust mobility, and improving the dust removal effect.

[0026] After cleaning the current platform 9, the drive mechanism 4 drives the dust hood 3 away from the platform 9, and the conveyor mechanism 2 starts to transport the next platform 9 to the dust removal station. This process continues, with the dust hood 3 removing dust from the platforms 9 on the conveyor mechanism 2. A robotic arm or battery conveying device then places the battery onto the dust-removed platform 9.

[0027] Specifically, when the platform 9 passes through the inlet and outlet 302 and is set in the inner cavity, there is a gap between the platform 9 and the inlet and outlet 302. When the air extraction mechanism 8 is working, air enters the inner cavity through the gap. Because the gap is small, it can increase the wind speed entering the inner cavity, which makes it easier to blow the dust away from the platform 9.

[0028] Specifically, the platform 9 can be a tray or a pallet.

[0029] In one embodiment, such as Figure 1and Figure 4 As shown, the first direction includes the first sub-direction X1, which is a straight line direction; It also includes a guide component 5, which is arranged along the second direction Y, and the second direction Y is set at an angle to the first sub-direction X1. The dust cover 3 is slidably connected to the bracket 1 through the guide component 5.

[0030] In this embodiment, such as Figure 1 and Figure 4 As shown, the first sub-direction X1 is a straight line, which makes it easy for the dust hood 3 to approach the platform 9 along the second direction Y, and also makes it easy for the platform 9 to correspond with the inlet and outlet 302 of the dust hood 3.

[0031] Specifically, the second direction Y is perpendicular to the first sub-direction X1, which facilitates the alignment of the platform 9 with the inlet / outlet 302.

[0032] Specifically, the first direction also includes a second sub-direction X2, which is along the curve direction.

[0033] In one embodiment, such as Figure 4 As shown, the guide assembly 5 includes a slider 501 and a guide rail 502 that are slidably connected. One of the slider 501 and the guide rail 502 is mounted on the dust cover 3, and the other is mounted on the bracket 1. The drive end of the drive mechanism 4 is connected to the dust cover 3 in a transmission manner.

[0034] In this embodiment, such as Figure 4 As shown, the connection structure between the slider 501 and the slide rail is simpler, and it can also guide the dust cover, so that the stage 9 can smoothly enter the inlet and outlet 302.

[0035] In some embodiments, the slider 501 is disposed on the dust cover 3 and the guide rail 502 is disposed on the bracket 1, so that the dust cover 3 is slidably connected to the bracket 1.

[0036] In some embodiments, the guide rail 502 is disposed on the dust cover 3, and the slider 501 is disposed on the bracket 1, so that the dust cover 3 is slidably connected to the bracket 1.

[0037] Specifically, the drive mechanism 4 is a cylinder, which is mounted on the bracket 1. The cylinder's extension rod is hinged to the slider 501 or to the dust cover 3.

[0038] Specifically, the drive mechanism 4 can be a ball screw mechanism.

[0039] In one embodiment, such as Figure 1 and Figure 4 As shown, the dust collector hood 3 has multiple inlets and outlets 302, which are arranged along the first sub-direction X1; The conveying mechanism 2 is equipped with multiple loading platforms 9, which can correspond one-to-one with multiple inlets and outlets 302.

[0040] In this embodiment, such as Figure 1 and Figure 4 As shown, the dust cover 3 is equipped with multiple inlets and outlets 302, which can clean multiple platforms 9 at the same time, thereby improving the cleaning efficiency of the platforms 9.

[0041] In one embodiment, such as Figure 1 and Figure 2 As shown, the conveying mechanism 2 includes a conveyor belt 201 and multiple mounting seats 202. Specifically, the conveyor belt 201 moves along a first direction; multiple mounting seats 202 are disposed on the conveyor belt 201, and each of the multiple mounting seats 202 is provided with a platform 9. Along the third direction Z, the projection of the platform 9 extends beyond the edge of the projection of the conveyor belt 201; wherein, the third direction Z is perpendicular to the plane where the conveyor belt 201 is located.

[0042] In this embodiment, such as Figure 1 and Figure 2 As shown, the projection of the platform 9 on the third direction Z exceeds the projection of the conveyor belt 201 on the third direction Z, which can ensure that when the dust hood 3 is close to the platform 9 and the platform 9 enters the cavity 301, the conveyor belt 201 avoids interfering with the dust hood 3.

[0043] Specifically, such as Figure 1 and Figure 2 As shown, the adjacent two platforms 9 are spaced apart, which allows multiple platforms 9 to pass through the inlet and outlet 302 at the same time.

[0044] Specifically, the conveying mechanism 2 also includes a drive motor, which is mounted on the bracket 1 and its output end is connected to the conveyor belt 201.

[0045] In one embodiment, such as Figure 1 and Figure 4 As shown, an air inlet 303 is provided on the side wall of the dust collector 3. The axial direction of the air inlet 303 is perpendicular to the plane of the platform 9, and the axial direction of the inlet and outlet 302 is parallel to the axial direction of the exhaust port 304.

[0046] In this embodiment, the axial direction of the air inlet 303 is perpendicular to the stage 9. Under the action of the air extraction mechanism 8, the airflow entering the cavity 301 through the air inlet 303 is perpendicular to the stage 9. At the same time, the airflow entering the cavity 301 from the inlet and outlet 302 is parallel to the stage 9. The two airflows form turbulence around the stage 9, which can overcome the adsorption force between the dust and the stage 9. It can apply pressure to the dust on the stage 9 from multiple angles, which facilitates the separation of the dust from the stage 9.

[0047] In one embodiment, such as Figure 2 As shown, at least one clamping component 6 is provided on the stage 9, which is adapted to clamp the battery.

[0048] In one embodiment (not shown), the clamping assembly 6 includes two clamping plates and two springs. One end of each spring is disposed on the stage 9, and the other end is connected to the two clamping plates respectively. The battery is clamped between the two clamping plates.

[0049] In one embodiment, such as Figure 2 As shown, the mounting base 202 includes a connecting plate 2021 and an extension plate 2022. The connecting plate 2021 is disposed on the conveyor belt 201. One end of the extension plate 2022 is connected to the connecting plate 2021, and the other end extends away from the edge of the conveyor belt 201. The platform 9 is disposed at the end of the extension plate 2022 away from the conveyor belt 201.

[0050] In this embodiment, the extension plate 2022 can extend out of the edge of the conveyor belt along the second direction Y, thereby enabling the platform 9 to move away from the conveyor belt 201 and preventing the dust cover 3 from being interfered with by the conveyor belt 201 when it moves along the second direction Y.

[0051] Specifically, the extension plate 2022 includes a transverse extension plate 20221 and a longitudinal extension plate 20222 connected to each other. The transverse extension plate 20221 extends along the second direction Y, and the longitudinal extension plate 20222 extends along the third direction Z.

[0052] In one embodiment, such as Figure 1 As shown, the conveyor belt 201 includes an arc segment 2011 and a straight segment 2012. The dust collector hood 3 corresponds to the straight segment 2012, and the straight segment 2012 extends along the first sub-direction X1.

[0053] In this embodiment, the conveyor belt 201 includes an arc segment 2011 and a straight segment 2012. The conveyor belt 201 forms a closed loop structure, which can drive the platform 9 to perform cyclic conveying and continuously clean the platform 9.

[0054] In one embodiment, such as Figure 4 As shown, the dust collector hood 3 has multiple air extraction holes 304, each corresponding to a multiple inlet / outlet 302. The multiple air extraction holes 304 are connected to the air extraction end of the air extraction mechanism 8 through the air extraction pipe assembly 7.

[0055] In this embodiment, providing multiple air extraction ports can increase the suction force, increase the air flow rate in the inner cavity, increase the pressure on the dust on the stage 9, and thus improve the dust removal effect on the stage 9.

[0056] In one embodiment, such as Figure 1 , Figure 3 and Figure 5 As shown, the air extraction pipe assembly 7 includes: a main pipe 701, multiple branch pipes 702 and a connector 703. Specifically, one end of the main pipe 701 is connected to the air extraction end of the air extraction mechanism 8; one end of each of the multiple branch pipes 702 is connected to multiple air extraction holes 304, and the other end is connected to the end of the main pipe 701 away from the air extraction mechanism 8 through the connector 703.

[0057] According to an embodiment of this application, another aspect provides a battery production line, including a dust removal device.

[0058] It should be noted that the battery production line includes the dust removal device provided in the embodiments of this application, and therefore includes all the advantages of the dust removal device mentioned above, so it will not be repeated here.

[0059] The following is an example, combined with Figures 1 to 5 A comprehensive explanation of all the above-mentioned plans is provided.

[0060] The drive motor drives the conveyor belt 201 to move, and the conveyor belt 201 moves the platform 9. The platform 9 is used to place batteries, and the conveyor belt 201 transports the batteries through the platform 9. However, before placing the batteries on the platform 9, the platform 9 needs to be cleaned to remove dust, without affecting the transport of batteries by the conveyor mechanism 2. During the movement of the conveyor belt 201, when the platform 9 is transported to the dust removal station, the drive motor stops, and the cylinder drives the dust removal hood 3 to slide on the bracket 1 and move from the first position to the second position. The dust removal hood 3 approaches the platform 9, and the platform 9 passes through the inlet and outlet 302 and enters the cavity 301. The air extraction mechanism 8 starts working to extract air from the cavity 301. Air enters the cavity 301 from the inlet and outlet 302 and exits from the extraction hole 304, forming an airflow in the cavity 301. The airflow entering from the inlet / outlet 302 is parallel to the stage 9, while the airflow entering from the inlet 303 is perpendicular to the stage 9. The two airflows form turbulence around the stage 9, which can overcome the adsorption force between the dust and the stage 9 and apply pressure to the dust on the stage 9 from multiple angles, making it easier to separate the dust from the stage 9 and improve the dust removal effect.

[0061] After cleaning the current platform 9, the cylinder drives the dust removal hood 3 away from the platform 9, the drive motor starts, and the next platform 9 is transported to the dust removal station. This process continues, with the dust removal hood 3 removing dust from the platforms 9 on the conveyor belt 201. A robotic arm or battery conveying device places the battery onto the dust-removed platform 9.

[0062] Although embodiments of this application have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of this application, and such modifications and variations all fall within the scope defined by the appended application.
