Description

Technical Field

[0001] This utility model belongs to the field of battery manufacturing technology, and specifically relates to a battery electrode conveying device. Background Technology

[0002] like Figure 1 As shown, after the battery electrode 01 is cut, it needs to be conveyed by a vacuum adsorption conveying device. The vacuum adsorption conveying device mainly includes a conveyor belt 02, a guide roller 03, and a support body 04. The support body 04 is equipped with a vacuum adsorption cavity. Since there is no vacuum adsorption force in the area between the guide roller 03 and the vacuum adsorption cavity, when the battery electrode 01 moves to the end of the conveyor belt 02, the battery electrode 01 is very likely to become misaligned due to insufficient adsorption force. Once the position of the battery electrode 01 becomes misaligned, it will always be in a misaligned state when entering the subsequent process. This not only increases the workload of correcting the misalignment of the battery electrode 01, but also easily leads to an increase in the defect rate of the battery electrode 01 when entering the subsequent processing. Utility Model Content

[0003] In view of this, the purpose of this utility model is to provide a battery electrode conveying device that can achieve stable conveying of battery electrodes and reduce the defect rate of battery electrodes during processing.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A battery electrode conveying device, comprising:

[0006] The supporting body includes a negative pressure cavity and multiple negative pressure holes communicating with the negative pressure cavity;

[0007] A conveyor roller is located at the conveying end of the support body;

[0008] A conveyor belt is sleeved around the outer periphery of the conveyor roller and the support body. The conveyor belt is provided with a plurality of through holes for adsorbing battery electrodes. The through holes are connected to the corresponding negative pressure holes.

[0009] A flow guide block is located between the conveyor roller and the support body. The flow guide block is provided with a flow guide groove. The first end of the flow guide groove is connected to the through hole of the conveyor belt located in the area of ​​the flow guide block, so as to form a negative pressure area between the flow guide block and the conveyor belt. The second end of the flow guide groove is connected to the negative pressure cavity.

[0010] As can be seen from the above technical solution, when conveying battery electrodes, the battery electrodes need to be placed at the through holes of the conveyor belt, and the conveyor roller is started. The conveyor roller drives the conveyor belt to run on the support body and the guide block. When the battery electrodes reach the support body, the negative pressure in the negative pressure cavity attracts the battery electrodes to the conveyor belt through the negative pressure hole and the through hole. When the battery electrodes reach the guide block, the negative pressure in the negative pressure cavity attracts the battery electrodes to the conveyor belt through the guide groove and the through hole.

[0011] Compared with the prior art, the battery electrode conveying device disclosed in this utility model can not only make the battery electrode adsorbed on the conveyor belt when running on the support body, but also make the battery electrode stably adsorbed on the conveyor belt by negative pressure when it reaches the area near the end of the conveyor roller. Therefore, the battery electrode conveying device can achieve stable conveying of battery electrodes, thereby effectively reducing the defect rate of battery electrodes in the processing.

[0029] In view of this, the purpose of this utility model is to provide a battery electrode conveying device that can achieve stable conveying of battery electrodes and reduce the defect rate of battery electrodes during processing.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Please refer to... Figures 2 to 10 .

[0031] Please refer to Figures 2 to 6The battery electrode conveying device disclosed in this embodiment includes a conveyor belt 100, a conveyor roller 200, a support body 300, and a guide block 400. The support body 300 includes a negative pressure cavity 304 and multiple negative pressure holes 3031 communicating with the negative pressure cavity 304. The conveyor roller 200 is located at the conveying end of the support body 300. The conveyor belt 100 is sleeved on the outer periphery of the conveyor roller 200 and the support body 300. The conveyor belt 100 is provided with multiple abutments for adsorbing battery electrodes. The through hole 101 of the plate is connected to the corresponding negative pressure hole 3031. The flow guide block 400 is located between the conveyor roller 200 and the support body 300. The flow guide block 400 is provided with a flow guide groove 401. The first end 4011 of the flow guide groove 401 is connected to the through hole 101 of the conveyor belt 100 located in the area of ​​the flow guide block 400, so as to form a negative pressure area between the flow guide block 400 and the conveyor belt 100. The second end 4012 of the flow guide groove 401 is connected to the negative pressure cavity 304.

[0032] When the battery electrode is being transferred, the conveyor roller 200 is started, and the conveyor roller 200 drives the conveyor belt 100 to run on the support body 300 and the guide block 400. The electrode to be transferred is placed on the conveyor belt 100. Since the through hole 101 on the conveyor belt 100 is connected to the corresponding negative pressure hole 3031, the negative pressure in the negative pressure cavity 304 is used to attract the battery electrode to the conveyor belt 100 for transfer through the negative pressure hole 3031 and the through hole 101. When the battery electrode reaches the area between the conveyor belt 100 and the conveyor roller 200, the negative pressure in the negative pressure cavity 304 is used to attract the battery electrode to the conveyor belt 100 through the guide groove 401 and the through hole 101.

[0033] Compared with the prior art, the battery electrode conveying device disclosed in this utility model embodiment not only allows the battery electrode to be adsorbed onto the conveyor belt 100 while running on the support body 300, but also allows the battery electrode to be stably adsorbed onto the conveyor belt 100 by negative pressure when it reaches the area near the end of the conveyor roller 200. Therefore, the battery electrode conveying device can achieve stable conveying of the battery electrode, thereby effectively reducing the defect rate of the battery electrode during the processing.

[0034] The conveyor belt 100 can be fully equipped with through holes 101, or it can be partially equipped with through holes 101. For example, a battery electrode adsorption area can be set on the conveyor belt 100, and through holes 101 can be set only in the battery adsorption area. The specific size of the battery adsorption area can be set according to actual needs.

[0035] For further embodiments, please refer to the following: Figure 4 and Figure 5The support body 300 has multiple slots, and a support portion 3032 for supporting the conveyor belt 100 is formed between each pair of adjacent slots. Negative pressure holes 3031 are located within the slots. This structure allows the negative pressure airflow generated at the negative pressure holes 3031 to be dispersed within the slots, ensuring that the through holes on the conveyor belt 100 corresponding to the slot areas can generate adsorption force on the battery electrodes. This ensures that the battery electrodes maintain adsorption force throughout the conveying process, further improving the stability of the battery electrode conveying.

[0036] The support body 300 can be one or more. Those skilled in the art can select the number of support bodies 300 and the specifications of the support bodies 300 according to actual needs.

[0037] As a further embodiment, please refer to Figure 4 and Figure 7 The present invention discloses that a plurality of diversion grooves 401 are provided along the extension direction of diversion block 400. Each diversion groove 401 is staggered with the negative pressure hole 3031. This arrangement can make the negative pressure in the area of ​​diversion block 400 and the negative pressure in the sink area relatively balanced, thereby further improving the uniformity of the adsorption force of the battery electrode.

[0038] The settling trough can extend in a direction parallel to the diversion block 400 or in a direction perpendicular to the diversion block 400.

[0039] As a specific embodiment of the present utility model, the sinking trough disclosed in the present utility model extends in a direction perpendicular to the diversion block 400. At this time, the diversion trough 401 and the side wall of the support portion 3032 between two adjacent sinking troughs are arranged opposite to each other. This structural arrangement can further improve the uniformity of the adsorption force of the battery electrode.

[0040] This embodiment of the utility model does not limit the specific structure of the diversion block 400. The diversion groove 401 can be a rectangular structure, an L-shaped structure, or other structures.

[0041] As a specific embodiment of this utility model, the side of the diversion block 400 near the support body 300 is configured as a flat structure, and the top of the side near the conveyor roller 200 is provided with an inclined surface 402. This structure can maximize the extension of the diversion groove 401 to the end region of the conveyor belt 100 near the conveyor roller 200, thereby increasing the negative pressure adsorption coverage area at the end of the conveyor belt 100 and thus improving the stability of battery electrode transfer.

[0042] It should be explained that the "top" disclosed in this embodiment of the utility model refers to the state of the conveying roller 200 when the battery electrode conveying device is working normally.

[0043] Please refer to Figure 6 and Figure 7 To ensure the normal operation of the conveyor roller 200, a certain distance needs to be maintained between the guide block 400 and the conveyor roller 200. If the distance is too small, collisions and interference may occur between the conveyor roller 200 and the guide block; if the distance is too large, the coverage area of ​​the guide block 400 at the end of the conveyor belt 100 will be reduced. Therefore, in this embodiment of the invention, the minimum distance n between the inclined surface 402 and the outer surface of the conveyor roller 200 is preferably set to 1mm-3mm to ensure smooth operation of the conveyor roller 200. As a specific embodiment of the invention, the minimum distance n between the inclined surface 402 and the outer surface of the conveyor roller 200 can be set to 1mm, 1.5mm, 2mm, or 3mm. The inclined surface 402 disclosed in this embodiment can be an arc-shaped surface or a straight surface, and this embodiment preferably uses an arc-shaped surface. The arc-shaped surface and the conveyor roller 200 can be concentric or non-concentric. If concentric, the distance from any point on the arc-shaped surface to the outer surface of the conveyor roller 200 is the minimum distance n. If an eccentric setting is used, the distance between the top of the arc-shaped surface and the outer surface of the conveyor roller 200 is the minimum distance n.

[0044] To further increase the negative pressure adsorption area of ​​the drainage block 400, the drainage groove 401 disclosed in this embodiment of the invention has an opening area that gradually increases from bottom to top. In this structure, the lower region with a smaller opening area can reduce the drop in negative pressure caused by the abrupt change in cross-section after the negative pressure airflow enters the drainage groove 401 from the negative pressure cavity 304, while the upper region with a larger opening area can increase the coverage area of ​​the negative pressure adsorption force.

[0045] The present invention does not limit the specific structure of the diversion groove 401. The diversion groove 401 can be a rectangular groove, a circular groove, or other shapes.

[0046] For specific embodiments of this utility model, please refer to the following: Figure 8 and Figure 9 The drainage channel 401 disclosed in this embodiment of the present invention includes a first drainage section 403 and a second drainage section 404, wherein the first drainage section 403 and the second drainage section 404 are connected. Specifically, the first drainage section 403 has a rectangular structure, and the second drainage section 404 has a trapezoidal structure. Under the action of the through hole, the second drainage section 404, and the first drainage section 403, the negative pressure in the negative pressure cavity 304 can stably adsorb the battery electrode onto the conveyor belt 100.

[0047] As a further embodiment, the top surface of the diverting block 400 disclosed in this embodiment is flush with the top surfaces of the supporting body 300 and the conveying roller 200. With this configuration, the upper surfaces of the diverting block 400, the supporting body 300, and the conveying roller 200 are on the same plane. When conveying the battery electrode sheets, the battery electrode sheets can always be conveyed smoothly on the same horizontal plane, avoiding positional displacement of the battery electrode sheets due to vibration caused by height differences during the conveying process.

[0048] The conveying rollers 200 disclosed in this utility model embodiment can be one set or two sets. As a specific embodiment of this utility model, the conveying rollers 200 disclosed in this utility model embodiment are two sets, and are respectively arranged at the beginning and end ends of the support body 300.

[0049] Each set of conveying rollers 200 is provided with a guide block 400 between it and the support body 300. This allows the battery electrode sheets at both ends to be adsorbed, thereby improving the stability of the battery electrode sheet conveying at both ends and ensuring the stability of the battery electrode sheets throughout the entire conveying process.

[0050] Each set of conveyor rollers 200 can be set with one, two, or more. When multiple conveyor rollers 200 are set, they are distributed along the height direction. Those skilled in the art can select according to their needs.

[0051] This utility model embodiment does not limit the specific installation method of the drainage block 400. The drainage block 400 and the support body 300 are detachably connected. Specifically, the drainage block 400 can be connected to the support body 300 through fasteners or other components, as long as the connection between the drainage block 400 and the support body 300 can be guaranteed to be stable.

[0052] For specific embodiments of this utility model, please refer to Figure 4 and Figure 10 The support body 300 disclosed in this embodiment of the utility model includes a support frame 301, a base plate 302 and a support plate 303. The support plate 303 is disposed on the upper part of the base plate 302. The support frame 301, the base plate 302 and the support plate 303 form a negative pressure cavity 304. A negative pressure hole 3031 is disposed on the support plate 303.

[0053] The base plate 302 has an air inlet 3021, which is connected to a negative pressure air source. The negative pressure air source enters the negative pressure chamber 304 through the air inlet 3021. The negative pressure in the negative pressure chamber 304 then adsorbs the battery electrode onto the conveyor belt 100 through the negative pressure hole 3031 and the through hole.

[0054] The negative pressure hole 3031 disclosed in this embodiment of the present invention can be a rectangular hole, a circular hole, or other shapes. As a specific embodiment of the present invention, the negative pressure hole 3031 disclosed in this embodiment of the present invention is an inverted conical hole, which can not only further increase the adsorption area of ​​the battery electrode and improve the adsorption force, but also help guide the airflow to be evenly distributed, reduce airflow turbulence, and make the negative pressure adsorption more stable.
