[0025] The electrode conveying device 200 includes a first-level inverted conveying assembly 201 and a second-level inverted conveying assembly 202 . DETAILED DESCRIPTION

[0026] 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.

[0027] 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.

[0028] 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.

[0029] like Figure 1-Figure 3 As shown, the waste kicking mechanism 100 according to the embodiment of the first aspect of the utility model includes a bracket 10 , a guide rail assembly 20 , a linear drive member 40 and a detection assembly 50 .

[0030] The support 10 is disposed below the gap between the primary inverted conveying assembly 201 and the secondary inverted conveying assembly 202 .

[0031] Specifically, Figure 1 As 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 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 by vacuum adsorption.

[0032] 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.

[0033] The guide rail assembly 20 is rotatably mounted on the bracket 10, and a waste kicking belt 30 is provided on the guide rail assembly 20. The linear drive member 40 is connected to the guide rail assembly 20, and is used to drive the guide rail assembly 20 to rotate between a horizontal state and an inclined state. The detection assembly 50 is electrically connected to the linear drive member 40, and the detection assembly 50 is used to detect whether the pole piece is qualified, and drive the linear drive member 40 according to the detection result.

[0034] Specifically, Figure 1-Figure 3 As shown, one end of the linear drive member 40 is connected to the guide rail assembly 20 , and one corner of the guide rail assembly 20 is rotatably disposed on the bracket 10 .

[0035] Therefore, when the linear drive member 40 is extended, the guide rail assembly 20 will move upward, and at this time, the upper surface of the guide rail assembly 20 is in a horizontal state.

[0036] When the linear drive member 40 contracts, the guide rail assembly 20 moves downward, and at this time, the upper surface of the guide rail assembly 20 is in a downwardly inclined state.

[0037] When the guide rail assembly 20 is in a horizontal state, the pole pieces on the primary inverted conveying assembly 201 can enter the secondary inverted conveying assembly 202 through the waste kicking belt 30 .

[0038] When the guide rail assembly 20 is in an inclined state, the pole pieces on the first-stage inverted conveying assembly 201 can be removed by the waste kicking belt 30 .

[0039] According to the damping rotor assembly of the embodiment of the utility model, a rotatable guide rail assembly 20 is arranged on the bracket 10, a waste kicking belt 30 is arranged on the guide rail assembly 20, and the top end of the linear drive member 40 is connected to the guide rail assembly 20, thereby, the guide rail assembly 20 can be rotated on the top of the bracket 10 through the telescopic action of the linear drive member 40. The guide rail assembly 20 rotates between a horizontal state and an inclined state. When the guide rail assembly 20 is in a horizontal state, the pole pieces on the first-level inverted conveying assembly 201 can enter the second-level inverted conveying assembly 202 through the waste kicking belt 30; when the guide rail assembly 20 is in an inclined state, the pole pieces on the first-level inverted conveying assembly 201 can be removed through the waste kicking belt 30. 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 pieces.

[0040] In some embodiments, Figure 1-Figure 2 As shown, the waste kicking mechanism 100 further includes a first rotating shaft 11 . The first rotating shaft 11 is disposed at the top end of the bracket 10 , and the guide rail assembly 20 is rotatably sleeved on the first rotating shaft 11 .

[0041] Specifically, Figure 1-Figure 2 As shown, by arranging the first rotating shaft 11 on the top end of the bracket 10, the first rotating shaft 11 effectively reduces the difficulty of assembling the guide rail assembly 20, and at the same time, helps to improve the stability of the guide rail assembly 20 during the rotation process.

[0042] In some embodiments, Figure 3 As shown, the guide rail assembly 20 includes a base plate 21 and a plurality of rollers 22 . The base plate 21 is rotatably mounted on the first rotating shaft 11 . The plurality of rollers 22 are arranged on the base plate 21 at intervals. The waste kicking belt 30 is mounted on the plurality of rollers 22 .

[0043] Specifically, Figure 3 As shown, the guide rail assembly 20 includes a bottom plate 21 and a plurality of rollers 22, and the waste kicking belt 30 is sleeved on the plurality of rollers 22. Thus, the stability of the waste kicking belt 30 is improved.

[0044] In some embodiments, Figure 3 As shown, the waste kicking mechanism 100 further includes a servo motor 12 , which is disposed on the bottom plate 21 and abuts against the waste kicking belt 30 to drive the waste kicking belt 30 to rotate.

[0045] Specifically, Figure 3 As shown, the servo motor 12 abuts against the scrap kicking belt 30 to drive the scrap kicking belt 30 to rotate. This is beneficial to reduce the accumulation of pole pieces on the scrap kicking belt 30.

[0046] In some embodiments, Figure 3As shown, the waste kicking mechanism 100 further includes a vacuum adsorption assembly 60 , which is disposed on the guide rail assembly 20 , and is used to generate adsorption force on the pole piece on the waste kicking belt 30 .

[0047] Specifically, Figure 3 As shown, the vacuum adsorption assembly 60 is arranged on the guide rail assembly 20 , which effectively improves the adsorption and stability of the pole piece on the scrap kicking belt 30 .

[0048] In some embodiments, Figure 3 As shown, the vacuum adsorption assembly 60 includes a vacuum chamber 61 , which is disposed on the guide rail assembly 20 and is located below the waste kicking belt 30 .

[0049] In some embodiments, Figure 3 As shown, the waste kicking mechanism 100 further includes a dust removal assembly 70 , which is disposed on the guide rail assembly 20 , and is used to clean the dust on the waste kicking belt 30 .

[0050] In some embodiments, the linear drive member 40 is a linear motor, and the detection component 50 is a line scan camera component.

[0051] like Figure 1 As shown, the pole piece conveying device 200 according to the embodiment of the second aspect of the utility model includes a primary inverted hanging conveying assembly 201 , a secondary inverted hanging conveying assembly 202 and a waste kicking mechanism 100 .

[0052] The first-stage inverted conveying assembly 201 is horizontally arranged, and the first-stage inverted conveying assembly 201 conveys the electrode invertedly by vacuum adsorption.

[0053] 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 invertedly by vacuum adsorption.

[0054] The waste kicking mechanism 100 is the waste kicking mechanism 100 of any of the above 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. The waste kicking mechanism 100 is used to remove unqualified pole pieces.

[0055] In some embodiments, the pole piece conveying device 200 also includes a speed adjustment component (not shown), which is disposed on the first-stage inverted conveying component 201, and the speed adjustment component is electrically connected to the detection component 50, and the speed adjustment component adjusts the operating speed of the first-stage inverted conveying component 201 according to the detection result of the detection component 50.

[0056] It is understandable that if Figure 1 As shown, before the pole piece is conveyed to the waste kicking mechanism 100, the pole piece is inspected by a line scan camera assembly.

[0057] When a defective piece is detected, the first-stage inverted conveyor assembly 201 starts to slow down to 50% of the normal speed. When the defective piece is transferred to the kicking belt 30, the kicking belt 30 moves to form an inclined angle to guide the piece to the waste box 3. After the defective piece is completely separated, it is reset. Due to the speed reduction, it can be ensured that the kicking belt 30 has enough time to reset and smoothly transport the subsequent pieces.

[0058] When the electrode is good, the scrap kicking belt 30 maintains a horizontal posture to ensure that the electrode passes smoothly and completes the conveying function.

[0059] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in the field can change, modify, replace and modify the above embodiments within the scope of the present invention.
