[0035] like Figure 1 As shown, the utility model provides a dust removal device, including a bracket 3, a first driving mechanism, a connecting mechanism, a second driving mechanism 23, a brushing mechanism, a suction mechanism 15 and a blowing mechanism; the first driving mechanism is arranged on the bracket 3, the driving end of the first driving mechanism is connected to the connecting mechanism, and can drive the connecting mechanism to reciprocate along the first direction; the second driving mechanism 23 is connected to the connecting mechanism, the brushing mechanism is connected to the driving end of the second driving mechanism 23, and the second driving mechanism 23 can drive the brushing mechanism to reciprocate in the second direction; the suction mechanism 15 and the blowing mechanism are both connected to the connecting mechanism, and the suction mechanism 15 is arranged corresponding to the brushing mechanism, the suction mechanism 15 is formed with a dust suction port for absorbing welding slag and dust brushed off by the brushing mechanism, and the blowing mechanism is formed with an air outlet for blowing away welding slag and dust.

[0036] Compared with the prior art, the dust removal device provided by the utility model has the following advantages:

[0037] The dust removal device provided by the utility model can provide an installation base for the first driving mechanism through the bracket 3. Since the driving end of the first driving mechanism in the present application can drive the connecting mechanism to reciprocate in the first direction, and the second driving mechanism 23 is connected to the connecting mechanism, and the second driving mechanism 23 can drive the brushing mechanism to reciprocate in the second direction, and the above-mentioned first direction in the present application is the vertical direction, and the second direction is the horizontal direction.

[0038] Therefore, when it is necessary to remove slag from the connecting piece, the first driving mechanism extends, thereby driving the connecting mechanism to move downward, and then causing the brushing mechanism to move downward and contact the connecting piece to be removed. After that, the second driving mechanism 23 continuously reciprocates in the second direction, thereby continuously brushing the welding surface of the connecting piece through the brushing mechanism until all the welding slag on the welding surface of the connecting piece is brushed away and the second driving mechanism 23 stops moving.

[0039] It can be understood that, since the connecting mechanism in the present application is also connected to a blowing mechanism and a suction mechanism 15, and the dust suction port of the suction mechanism 15 is arranged corresponding to the brushing mechanism, the welding slag brushed off by the brushing mechanism can be absorbed by the suction force of the suction mechanism 15, and accordingly, the air outlet formed by the blowing mechanism can blow away the airflow, thereby blowing away the welding slag and dust, achieving the cleanliness of the welding surface of the connecting piece, ensuring the welding effect of the connecting piece in the subsequent assembly process, and improving the battery quality.

[0040] Alternatively, if Figure 1 Combination Figure 2 As shown, the brushing mechanism in the present application includes a brush 26 and a mounting assembly, the mounting assembly includes a first connecting member 24 and a mounting member 25, the first connecting member 24 is connected to the driving end of the second driving mechanism 23, the mounting member 25 is connected to the first connecting member 24, and the brush 26 is connected to the mounting member 25.

[0041] The second driving mechanism 23 in the present application can be a telescopic structure capable of realizing linear motion, such as a cylinder, an oil cylinder, or an electric telescopic rod. Preferably, the second driving mechanism 23 in the present application is a cylinder. Since it is difficult to directly install a structure such as a brush 26 on the driving end of the cylinder, the present application connects the first connecting member 24 to the driving end of the cylinder, and further arranges a mounting member 25 on the first connecting member 24, so as to realize the connection between the brush 26 and the first driving mechanism.

[0042] Alternatively, if Figure 1 Combination Figure 2 As shown, the connecting mechanism in the present application includes a second connecting member 20, and the brushing mechanism also includes a fixed plate 21 and a dust cover 22. The fixed plate 21 is connected to the second connecting member 20, and the second driving mechanism 23 is arranged on the fixed plate 21; the dust cover 22 is connected to the second connecting member 20 and the fixed plate 21 to form a dustproof space, the second driving mechanism 23 and the mounting assembly are both arranged in the dustproof space, and the brush head end of the brush 26 is located outside the dust cover 22.

[0043] The dust cover 22 in the present application is also formed with an escape opening 12 at the position corresponding to the brush 26 , and the width of the escape opening 12 is not less than the displacement of the brush 26 in the second direction, thereby avoiding the problem of the dust cover 22 interfering with the operation of the brush 26 .

[0044] Accordingly, in this embodiment, the driving end of the first driving mechanism can be directly connected to the second connecting member 20, and the second connecting member 20 in the present application can be a plate-like structure with a certain installation area, so as to realize the connection and installation of the driving end of the first driving mechanism, the suction mechanism 15 and the blowing mechanism. In addition, the present application can provide an installation foundation for the installation of the second driving mechanism 23 by setting a fixing plate 21 on the second connecting member 20. Accordingly, by connecting a dust cover 22 to the second connecting member 20 and the fixing plate 21, it is possible to prevent welding slag or dust from affecting the action of the second driving mechanism 23 to a certain extent, thereby improving the stability of the overall device operation and the service life of the second driving mechanism 23.

[0045] Alternatively, if Figure 1 As shown, the first driving mechanism in the present application includes a fixing frame 4 and a driving member 5, the fixing frame 4 is connected to the bracket 3, the driving member 5 is connected to the fixing frame 4, and the driving member 5 extends along the first direction, and the driving end of the driving member 5 is connected to the connecting mechanism.

[0046] The driving member 5 in the present application may also adopt a linear telescopic structure such as an oil cylinder or an electric telescopic rod, but preferably, the driving member 5 in the present application is the same as the second driving mechanism 23, both adopting a cylinder, so that the reciprocating motion of the connecting mechanism in the first direction is achieved through the extension and contraction of the cylinder.

[0047] Correspondingly, the present application can provide an installation base for the driving member 5 by arranging the fixing frame 4 on the bracket 3, thereby ensuring the stable installation of the driving member 5.

[0048] Alternatively, if Figure 1 As shown, the first driving mechanism in the present application also includes a guide assembly and a third connecting member 8; the guide assembly includes a slider 9 and a guide rail 7, the guide rail 7 is laid on the fixed frame 4, the slider 9 is slidably set on the guide rail 7, the third connecting member 8 is connected to the slider 9, the driving end of the driving member 5 is connected to the third connecting member 8, and the second connecting member 20 is connected to the third connecting member 8.

[0049] By laying the guide rail 7 on the fixed frame 4 and slidingly setting the slider 9 on the guide rail 7, the third connecting member 8 is connected to the slider 9, and the driving end of the driving member 5 is connected to the third connecting member 8. Therefore, through the cooperation of the guide rail 7 and the slider 9, the driving end of the driving member 5 can be auxiliary guided and limited, so as to avoid the telescopic end of the driving member 5 from being too long and shaking when it is extended.

[0050] Furthermore, since the second driving mechanism 23 in the present application needs to drive the brush 26 to reciprocate in the second direction, and the brush 26 needs to clean the welding slag, a certain amplitude of vibration will be generated. Through the cooperation of the slider 9 and the guide rail 7, the influence of the vibration on the driving member 5 can be eliminated to a certain extent, thereby improving the stability of the overall device.

[0051] It is understandable that if Figure 1 As shown, the first driving mechanism in the present application further includes a floating joint 6 , which is connected to the driving end of the driving member 5 , and one end of the floating joint 6 away from the driving member 5 is connected to the third connecting member 8 .

[0052] Since the driving end of the driving member 5 is prone to displacement during installation, the present application also provides a slider 9 and a guide rail 7 to cooperate to limit and guide the movement of the driving end of the driving member 5. Therefore, the present application connects a floating joint 6 to the driving end of the driving member 5. This can compensate for the deviation between the driving end of the driving member 5 and the third connecting member 8 to a certain extent, thereby avoiding the jamming problem of the driving end of the driving member 5 during extension and retraction, thereby improving the smoothness of the operation of the overall device.

[0053] Furthermore, when the driving member 5 is overstretched to a certain extent, the floating joint 6 can compensate for this, thereby preventing the brush head end of the brush 26 from bending and affecting the brushing effect.

[0054] Furthermore, if Figure 1 Combination Figure 2 As shown, the connecting mechanism in the present application includes a buffer assembly, which includes an elastic member 16, a fourth connecting member 10, a guide rod 18 and a fifth connecting member 19; the fourth connecting member 10 is connected to the third connecting member 8, one end of the guide rod 18 is connected to the second connecting member 20, and the other end passes through the fourth connecting member 10 and is connected to the fifth connecting member 19; the elastic member 16 is sleeved on the guide rod 18, and is located between the side of the fifth connecting member 19 facing away from the fourth connecting member 10 and the end of the guide rod 18.

[0055] The second connecting member 20 in the present application is connected to the fifth connecting member 19 through the guide rod 18, and the guide rod 18 is slidably connected to the fourth connecting member 10. When the brush 26 contacts the connecting plate and is thrust by the connecting plate, the thrust can be transmitted to the second connecting member 20. Since one end of the guide rod 18 is fixedly connected to the second connecting member 20 and the other end is fixedly connected to the fifth connecting member 19, the guide rod 18 can slide relative to the fourth connecting member 10 and drive the fifth connecting member 19 to move in a direction away from the fourth connecting member 10.

[0056] Since the elastic member 16 is sleeved on the guide rod 18 in the present application, and the elastic member 16 is located between the side of the fifth connecting member 19 away from the fourth connecting member 10 and the end of the guide rod 18, when the fifth connecting member 19 moves upward, it can compress the elastic member 16 to achieve buffering.

[0057] It can be understood that when the driving member 5 contracts and drives the third connecting member 8 to move upward, the brushing mechanism and the second driving mechanism 23 are affected by gravity and drive the second connecting member 20 to move downward, thereby causing the fifth connecting member 19 to move downward until the fifth connecting member 19 is in contact with the fourth connecting member 10, and then the brush 26 is driven to leave the connecting plate through the continuous contraction of the driving member 5.

[0058] Preferably, if Figure 1 As shown, the buffer assembly in the present application also includes a linear bearing 11, which is connected to the fourth connecting member 10, and a guide rod 18 is arranged through the linear bearing 11. The end of the guide rod 18 away from the second connecting member 20 forms a limiting portion 17, and one end of the elastic member 16 abuts against the limiting portion 17.

[0059] The linear bearing 11 in the present application is connected to the side of the fourth connecting member 10 facing the second connecting member 20 , and the guide rod 18 is arranged through the linear bearing 11 , thereby achieving the purpose of the guide rod 18 moving relative to the fourth connecting member 10 .

[0060] The elastic member 16 in the present application is a tension spring. By forming a limiting portion 17 at the end of the guide rod 18, the elastic member 16 can be limited to ensure stable realization of the buffering function.

[0061] Alternatively, if Figure 1 As shown, the blowing mechanism in the present application includes a blowing pipe 13, a blowing head 1 and a manifold 14, an air outlet is formed on the blowing head 1, the blowing head 1 is connected to one end of the blowing pipe 13, the other end of the blowing pipe 13 is connected to the manifold 14, and the manifold 14 is arranged on the second connecting member 20.

[0062] In addition, the utility model also provides a welding dust removal system, including a placement fixture 2 and the above-mentioned dust removal device, and the placement fixture 2 can transport the connecting piece to be cleaned to the dust removal device for cleaning.

[0063] The welding dust removal system using the dust removal device provided in the present application can effectively remove the welding slag and dust generated by welding and adhered to the connecting piece, thereby ensuring the cleanliness of the welding surface of the connecting piece to a certain extent, improving the welding effect during subsequent welding operations, and ensuring the quality of the battery.

[0064] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
