[0030] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0032] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "provided with", "connected", etc. should be understood in a broad sense. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0033] As described in the background technology, in the production process of lithium batteries, the quality and production efficiency of the lamination process play an extremely important role in improving the quality of lithium battery products and the overall production efficiency. Before lamination, the cut positive and negative electrode sheets need to be transported to the lamination station. After the position is recognized by the visual camera and the secondary positioning of the electrode sheets is completed by the UVW platform, the positive and negative electrode sheets are stacked one by one as needed by the lamination robot. At present, the electrode sheet conveying method of lamination equipment in the market is mainly vacuum belt, which combines the visual system and UVW platform to complete the precise positioning of the electrode sheets. Among them, the existing lamination equipment uses an inverted belt kicking form, which visually identifies defective products, and the electrode sheets are removed at the kicking position. The belt is in a stopped state when kicking. However, due to the short stop time of the equipment beat, the kicking is carried out by switching the air path, which makes the kicking unstable and prone to errors.

[0034] In order to improve the above problems, in the first aspect of the present application, a pole piece kicking mechanism is proposed, referring to Figure 1 and Figure 2 , which mainly includes: a first conveyor belt 1, a second conveyor belt 2, a detection device 3, a waste kicking component 4 and a guide shaft 5.

[0035] Specifically, in the exemplary embodiment, the first conveyor belt 1 and the second conveyor belt 2 are both vacuum inverted belts, and can vacuum-absorb the electrode pieces and defective products thereon, and convey the electrode pieces along a preset direction.

[0036] Furthermore, in the exemplary embodiment, a preset gap is formed between the first conveyor belt 1 and the second conveyor belt 2, and the waste kicking assembly 4 is disposed at the preset gap and is capable of removing defective products from the conveyor belts.

[0037] Specifically, in the exemplary embodiment, the detection device 3 is a visual scanning camera located below the first conveyor belt 1. It can scan the pole piece, identify defective products, and send an electrical signal to the kicking component 4 to control its operation. The detection device 3 has the characteristics of high resolution and fast response, and can accurately judge the quality of the pole piece and provide real-time feedback.

[0038] Furthermore, in the exemplary embodiment, the detection device 3 is also electrically connected to the driving device of the first conveyor belt 1. After the detection device 3 identifies defective products, the driving device of the first conveyor belt 1 can be decelerated, thereby slowing down the speed of the first conveyor belt 1, thereby improving the stability of the waste kicking component 4.

[0039] Specifically, in the exemplary embodiment, the waste kicking component 4 is disposed in a preset gap between the first conveyor belt 1 and the second conveyor belt 2 and is connected to the detection device 3 so as to kick out defective products.

[0040] Further, in the exemplary embodiment, referring to Figure 2 and Figure 3The waste kicking component 4 includes a servo motor 41 and a swing rod 42. The servo motor 41 is fixed to one side of the output end of the first conveyor belt 1, and the output shaft of the servo motor 41 is arranged toward the first conveyor belt 1. The servo motor 41 is electrically connected to the detection device 3, and can receive the electrical signal sent by the detection device 3 and trigger the preset stroke. The swing rod 42 is made of carbon fiber material, and one end of the swing rod 42 is radially connected to the output shaft of the servo motor 41, and can swing with the rotation of the output shaft of the servo motor 41, so that when the defective products are conveyed between the first conveyor belt 1 and the second conveyor belt 2, the other end of the swing rod 42 abuts against the upper side of the pole piece and applies force until the pole piece is detached from the first conveyor belt 1 and the second conveyor belt 2, thereby removing the defective products from between the first conveyor belt 1 and the second conveyor belt 2.

[0041] Furthermore, in the exemplary embodiment, two waste kicking assemblies 4 are provided, and are respectively arranged on both sides of the output end of the first conveyor belt 1. The two waste kicking assemblies 4 work together to further improve the stability of rejecting defective products.

[0042] Specifically, in the exemplary embodiment, the guide shaft 5 is made of carbon fiber material and is horizontally arranged between the first conveyor belt 1 and the second conveyor belt 2. When the pole piece is conveyed between the first conveyor belt 1 and the second conveyor belt 2, it can play an auxiliary supporting role and guide the pole piece so that it can be conveyed to the input end of the second conveyor belt 2 and be adsorbed by the second conveyor belt 2.

[0043] Further, in the exemplary embodiment, the distance between the guide shaft 5 and the input end of the second conveyor belt 2 is 2 mm-3 mm.

[0044] Furthermore, in the exemplary embodiment, both ends of the guide shaft 5 are rotatably connected to the frame of the second conveyor belt 2 via bearings to reduce the friction between the guide shaft 5 and the pole piece.

[0045] In summary, compared with the existing waste kicking method, the waste kicking assembly 4 composed of a servo motor 41 and a rocker arm 42 is used in this application, which can more stably remove defective products from between the first conveyor belt 1 and the second conveyor belt 2, avoiding errors and mistakes in the waste kicking process. There is no need to stop the belt during the waste kicking process, which can improve the overall production efficiency, speed up the production rhythm, and reduce production costs. At the same time, the electrode conveying system in this application can also realize the efficient transportation and classification of electrodes, including the collection of good electrodes and the removal of defective products.

[0046] In the second aspect of the present application, a pole piece conveying system is also proposed, which includes the pole piece kicking mechanism described above, and also includes a pole piece collecting mechanism and a defective product collecting mechanism. Among them, the pole piece collecting mechanism is arranged at the output end of the second conveyor belt 2, and is suitable for collecting good pole pieces; the defective product collecting mechanism is arranged below the kicking component 4, and is suitable for collecting defective products. All of the above belong to the prior art and will not be repeated here.

[0047] Finally, it should be noted that the above is only a preferred embodiment of the present application and is not intended to limit the present application. Although the present application is described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
