[0031] The technical solution of the utility model will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0032] It is understandable that when the existing inverted belt is kicking out the scrap, the pole piece needs to be stopped and removed in the kicking area. The whole machine cycle is limited to a short stopping time, resulting in unstable kicking, which has become a major bottleneck for improving the cycle of the stacking machine.

[0033] To this end, an embodiment of the utility model provides a waste kicking mechanism for a pole piece conveying device 200 and a pole piece conveying device 200 having the waste kicking mechanism.

[0034] like Figure 1-Figure 8 As shown, the waste kicking mechanism 100 according to the embodiment of the first aspect of the utility model includes a bracket 10 , a linear drive member 20 , a handle 30 and a detection assembly 40 .

[0035] The support 10 is disposed below the gap between the primary inverted conveying assembly 201 and the secondary inverted conveying assembly 202 .

[0036] Specifically, Figure 1As shown, the first-level inverted conveying assembly 201 is horizontally arranged, and the first-level inverted conveying assembly 201 inverts and conveys the electrode piece 203 by vacuum adsorption. The second-level inverted conveying assembly 202 is horizontally arranged, and the second-level inverted conveying assembly 202 is located in the conveying direction of the first-level inverted conveying assembly 201, and there is a gap between the second-level inverted conveying assembly 202 and the first-level inverted conveying assembly 201, and the second-level inverted conveying assembly 202 inverts and conveys the electrode piece 203 by vacuum adsorption.

[0037] It is understandable that, due to the lack of vacuum at a certain distance between the two belt sections, the pole piece sags and deforms in the suspended part under the action of gravity. Among them, when the positive pole piece is suspended for 40mm, the deformation of the pole piece is 1.3mm; when the negative pole piece is suspended for 40mm, the deformation is 7.56mm. Therefore, an additional device is needed to realize the function of kicking out bad pole pieces and ensure the stable transition of good pole pieces from the first-level inverted conveying assembly 201 to the second-level inverted conveying assembly 202.

[0038] One end of the linear drive member 20 is rotatably disposed at the bottom end of the bracket 10, and the other end of the linear drive member 20 extends toward the top end of the bracket 10. The dial hand 30 is rotatably disposed on the top end of the bracket 10, and the dial hand 30 is connected to the other end of the linear drive member 20.

[0039] Specifically, Figure 2 As shown, the lower end of the linear drive member 20 is rotatably disposed on the bottom end of the bracket 10 , and the upper end of the linear drive member 20 is rotatably disposed on the pull handle 30 .

[0040] Therefore, when the linear drive member 20 is extended, the front end of the pusher 30 will move forward and downward. At this time, the pusher 30 cannot remove the pole piece 203.

[0041] When the linear drive member 20 contracts, the front end of the pusher 30 moves backward and upward. At this time, the pusher 30 can remove the pole piece 203 .

[0042] The detection assembly 40 is electrically connected to the linear drive member 20, and is used to detect whether the pole piece 203 is qualified, and drive the linear drive member 20 according to the detection result. The linear drive member 20 can drive the hand 30 to rotate, so that the hand 30 can extend upward into the gap between the first inverted conveying assembly 201 and the second inverted conveying assembly 202 to remove unqualified pole pieces 203.

[0043] According to the waste kicking mechanism 100 of the embodiment of the utility model, a rotatable linear drive member 20 is arranged at the bottom of the bracket 10, a rotatable hand 30 is arranged at the top of the bracket 10, and the top of the linear drive member 20 is connected to the hand 30, thereby, through the telescopic action of the linear drive member 20, the hand 30 can be rotated at the top of the bracket 10. The hand 30 can be rotated into the gap between the primary inverted conveying assembly 201 and the secondary inverted conveying assembly 202, thereby, the unqualified pole piece 203 conveyed from the primary inverted conveying assembly 201 to the secondary inverted conveying assembly 202 will hit the hand 30, and the hand 30 can remove the unqualified pole piece 203. The waste kicking mechanism 100 of the utility model has a small rotation range and a fast removal action, which effectively improves the removal efficiency of the pole piece 203.

[0044] In some embodiments, Figure 2 As shown, the waste kicking mechanism 100 further includes a rotating shaft 11 , which is disposed on the top end of the bracket 10 , and the handle 30 is rotatably sleeved on the rotating shaft 11 .

[0045] Specifically, Figure 2 As shown, by arranging the rotating shaft 11 on the top end of the bracket 10, the rotating shaft 11 effectively reduces the difficulty of assembling the dial handle 30, and at the same time, helps to improve the stability of the dial handle 30 during the rotation process.

[0046] In some embodiments, Figure 3-Figure 4 As shown, the linear drive member 20 can drive the hand 30 to rotate between a first position and a second position. In the first position, the hand 30 is in a horizontal position, and the pole piece 203 on the primary inverted conveying assembly 201 can pass through the upper surface of the hand 30 and enter the secondary inverted conveying assembly 202. In the second position, the hand 30 is in a waste kicking position, and the pole piece 203 on the primary inverted conveying assembly 201 hits the lower surface of the hand 30 and is removed.

[0047] It is understandable that if Figure 4 As shown, when a defect is detected, a signal is sent to the linear drive member 20, and the linear drive member 20 causes the handle 30 to form an upward tilt angle. At this time, the pole piece 203 deformed by gravity will enter the arc segment of the waste kicking handle 30, and the pole piece 203 will be separated under the action of the first-level inverted conveying assembly 201 (a part of the pole piece 203 is still in the vacuum area) and the handle 30, completing the waste kicking function, and then resetting.

[0048] It is understandable that, since the hand 30 needs to be swung at a very small angle to be reset to a horizontal position, the time of this action will not affect the subsequent transportation of good films, and the realization of dynamic kicking can be ensured.

[0049] It is understandable that if Figure 3As shown, when the electrode 203 is a good product, the scrap kicking hand 30 maintains a horizontal position, so that the drooping and deformed part of the electrode 203 contacts the upper horizontal section of the scrap kicking hand 30, and the electrode 203 is pushed forward by the forward force of the first-level inverted conveying assembly 201 (a part of the electrode 203 is still in the vacuum area) until it smoothly enters the negative pressure area of ​​the second-level inverted conveying assembly 202, completing the normal conveying function of good electrodes.

[0050] In some embodiments, Figure 5-Figure 6 As shown, the upper surface of the dial handle 30 is a horizontal surface, and the lower surface of the dial handle 30 is an arc surface.

[0051] Specifically, Figure 5-Figure 6 As shown, the upper surface of the handle 30 is a horizontal plane, which is beneficial to improve the smoothness of the pole piece 203 during the transportation process and prevent the pole piece 203 from being bumped.

[0052] Specifically, Figure 5-Figure 6 As shown, the lower surface of the handle 30 is an arc-shaped surface, thereby making the removal trajectory of the pole piece 203 smoother and preventing the pole piece 203 from rebounding and splashing.

[0053] In some embodiments, Figure 7 As shown, the waste kicking mechanism 100 further includes a first connecting member 50 and a first fixing member (not shown). The first connecting member 50 is disposed at the bottom end of the bracket 10, and a first connecting hole 51 is disposed on the first connecting member 50. Two symmetrically disposed first connecting portions 21 are disposed at one end of the linear drive member 20, and the two first connecting portions 21 are disposed on both sides of the first connecting hole 51, and the first fixing member is sequentially inserted into the first connecting hole 51 and the two first connecting portions 21.

[0054] In some embodiments, Figure 8 As shown, the waste kicking mechanism 100 further includes a second connecting member 60 rotatably disposed at the other end of the linear driving member 20 , and a second connecting portion is disposed on the handle 30 rotatably connected to the second connecting member 60 .

[0055] In some embodiments, the linear drive member 20 is a linear motor.

[0056] In some embodiments, the detection component 40 is a line scan camera component.

[0057] The pole piece conveying device 200 according to the embodiment of the second aspect of the utility model comprises a primary inverted hanging conveying assembly 201 , a secondary inverted hanging conveying assembly 202 and a waste kicking mechanism 100 .

[0058] The first-stage inverted conveying assembly 201 is horizontally arranged, and the first-stage inverted conveying assembly 201 conveys the electrode 203 invertedly by vacuum adsorption.

[0059] The secondary inverted conveying assembly 202 is horizontally arranged, and is located in the conveying direction of the primary inverted conveying assembly 201, and there is a gap between the secondary inverted conveying assembly 202 and the primary inverted conveying assembly 201. The secondary inverted conveying assembly 202 conveys the electrode 203 invertedly by vacuum adsorption.

[0060] The waste kicking mechanism 100 is the waste kicking mechanism 100 of any of the above-mentioned embodiments. The waste kicking mechanism 100 is arranged below the gap between the first-level inverted conveying assembly 201 and the second-level inverted conveying assembly 202.

[0061] In some embodiments, Figure 1 As shown, the detection component 40 is arranged on the first-level inverted conveying component 201 , and the top end of the bracket 10 is connected to the second-level inverted conveying component 202 .

[0062] Specifically, Figure 1 As shown, the detection component 40 is arranged on the first-level inverted conveying component 201 , thereby facilitating the detection component 40 to better detect the pole piece 203 .

[0063] Specifically, Figure 1 As shown, the top end of the bracket 10 is connected to the secondary inverted conveying assembly 202 , thereby improving the stability of the bracket 10 .
