Description

Technical Field

[0001] This utility model relates to the field of blade battery manufacturing technology, specifically to a blade battery suction plate based on partitioned adsorption and backflushing optimization. Background Technology

[0002] Since BYD launched its first-generation blade battery, battery technology has undergone significant progress and development. As the market's requirements for energy density and charging efficiency continue to increase, lithium iron phosphate batteries still occupy the mainstream position in the market due to their low cost, simple thermal management, and higher safety.

[0003] The existing technical problem is:

[0004] Electrode detachment phenomenon: When traditional suction plates adsorb electrodes, the electrodes are difficult to detach due to static electricity accumulation or vacuum residue, which causes transport deviation and a decrease in yield.

[0005] Material defects: Ordinary metal / plastic suction plates are prone to static electricity, which exacerbates the adsorption of residues.

[0006] Low separation efficiency: It relies on vacuum release for natural desorption, which cannot separate quickly and requires manual intervention.

[0007] Uneven adsorption: The traditional adsorption pores are not distributed properly, resulting in insufficient local adsorption force or overload, which causes the electrode to wrinkle and deform.

[0008] Limitations of existing technology:

[0009] Poor adaptability to low-temperature environments: the performance of ordinary materials degrades more rapidly at low temperatures;

[0010] High maintenance costs: The suction plate needs to be replaced frequently due to static electricity or mechanical wear.

[0011] Therefore, a blade battery suction plate based on partitioned adsorption and backflushing optimization is needed. Utility Model Content

[0012] To address the problems existing in the prior art, this utility model provides a blade battery suction plate based on partitioned adsorption and backflushing optimization. The purpose is to solve the technical problem that the suction plate structure used in the existing blade battery production process is prone to producing sheet-carrying phenomena, resulting in defective products and losses.

[0013] To achieve the above objectives, this utility model is implemented through the following technical solution: a blade battery suction plate based on partitioned adsorption and backflushing optimization, comprising a suction plate body and a suction plate mounting base connected to the suction plate body. The surface of the suction plate body that contacts the electrode is provided with an adsorption groove, and an adsorption hole is provided inside the adsorption groove. The adsorption hole is connected to the air intake channel opened in the suction plate body, and the air intake channel is connected to the air intake hole connected to the outside. The adsorption groove adopts a symmetrical structure, forming a sealed adsorption area on the surface of the suction plate body, and the adsorption holes are symmetrically distributed in the adsorption groove.

[0015] Preferably, the backflush hole is arranged adjacent to the adsorption groove and protrudes outward.

[0016] Preferably, the suction channel and the backflush channel are staggered within the suction plate body.

[0017] Preferably, the suction plate body and the suction plate mounting base are integrated into one structure. The suction plate mounting base is provided with an air intake hole and a back-blowing port. The air intake channel is connected to the air intake hole, and the back-blowing channel is connected to the back-blowing port.

[0018] Preferably, the adsorption grooves are distributed in a U-shape on the surface of the suction plate body, and a connecting groove is provided in the middle to connect the U-shaped structures.

[0022] 2. The suction plate body of this utility model is provided with backflush holes, which can quickly separate the suction plate from the electrode by introducing nitrogen gas, further eliminating the phenomenon of the suction plate carrying the electrode.

[0023] 3. The suction plate body of this utility model has an adsorption groove on the surface that mates with the electrode. The adsorption groove forms an adsorption area, which can increase the adsorption area and improve the adsorption force, so that the electrode can be subjected to force evenly on the adsorption surface.

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] like Figures 1 to 4 As shown, the blade battery suction plate based on partitioned adsorption and backflushing optimization provided by this utility model includes a suction plate body 10 and a suction plate mounting base 11 connected to the suction plate body 10. The suction plate body 10 has adsorption holes 7 on the surface in contact with the electrode and an air intake channel 5 inside for communicating with the adsorption holes 7. The air intake channel 5 is connected to the air intake hole 4. The suction plate body 10 has adsorption grooves 6 on the surface where the adsorption holes 7 are set. The adsorption grooves 6 adopt a symmetrical structure to form a sealed adsorption area on the surface of the suction plate body 10. The adsorption holes 7 are symmetrically distributed in the adsorption grooves 6. In the embodiment of this utility model, the adsorption grooves 6 are distributed in a U-shape on the surface of the suction plate body 10, and a connecting groove is provided in the middle to connect the U-shaped structure.

[0031] The adsorption groove 6 makes the adsorption area formed on the surface of the suction plate body 10 more uniform when the adsorption hole 7 draws air, ensuring the adsorption effect on the electrode. In order to facilitate the separation between the suction plate and the electrode, the suction plate body 10 of this utility model is made of aluminum nitride ceramic to reduce the static electricity generated by the suction plate itself. At the same time, a backflush hole 8 is provided through the suction plate body 10, and a backflush flow channel 1 connected to the backflush hole 8 is provided inside the suction plate body 10.

[0032] To avoid interference between the backflush hole 8 and the suction hole 4, which would affect the adsorption effect, this invention uses a suction plate body 10 with evenly distributed protrusions. The end face of the protrusion is set as the backflush port surface 9, and backflush holes 8 are symmetrically arranged on the backflush port surface 9. A backflush channel 1 communicating with the backflush holes 8 is set in the suction plate body 10. The backflush holes 8 are located in the adsorption area formed by the adsorption groove 6 on the suction plate body 10, and are set on the surface of the suction plate body 10 where the adsorption groove 6 is not provided. After the electrode is attached to the surface of the suction plate body 10, the magnitude of the adsorption force will not be affected by the backflush holes 8.

[0033] The suction plate body 10 and the suction plate mounting base 11 of this utility model adopt an integral structure. The suction air channel 5 and the back-blowing air channel 1 are staggered in the suction plate body 10. The suction plate mounting base 11 is provided with a suction hole 4 and a back-blowing port 3. The suction air channel 5 is connected to the suction hole 4, and the back-blowing air channel 1 is connected to the back-blowing port.

[0034] The blade battery suction plate based on partitioned adsorption and backflushing optimization provided by this utility model is fixed by the suction plate mounting base and driven by the driving device to move the suction plate to adsorb the electrode. During adsorption, the surface of the suction plate body 10 is in contact with the electrode. The suction end, through the suction hole 4 and the suction flow channel 5, forms a negative pressure at the adsorption hole 7 to draw in air and form a stable adsorption force in the adsorption groove to adsorb the electrode. When it is necessary to place the electrode and separate the suction plate from the electrode, the suction end stops drawing in air, and at the same time, nitrogen is introduced into the backflushing flow channel 1 through the backflushing port. The nitrogen is blown out through the backflushing hole, thereby eliminating the phenomenon of the suction plate carrying the electrode and reducing the defect rate.

[0035] (1) The technical objective of this patent solution is:

[0036] 1. Eliminate electrode adhesion: By using aluminum nitride ceramic material (antistatic) and backflushing airflow design, the electrode adhesion caused by electrostatic adsorption and vacuum residue is solved.

[0037] 2. Improve adsorption stability: The adsorption force is evenly distributed in the partitioned area through the U-shaped adsorption groove and symmetrically distributed adsorption pores, avoiding electrode shift or deformation.

[0038] 3. Rapid separation requirement: Nitrogen backflushing technology is introduced to achieve millisecond-level electrode desorption, adapting to the pace of high-speed production lines.

[0039] (2) The beneficial effects of the technical solution of the present invention:

[0040] Antistatic and durable: Aluminum nitride ceramic materials reduce surface charge accumulation and reduce electrostatic adsorption; the high hardness and wear resistance of ceramics extend the life of the suction plate.

[0041] High-efficiency separation mechanism: The backflush hole and the suction channel are staggered to avoid airflow interference and ensure rapid switching between adsorption / backflush modes; nitrogen backflush acts directly on the electrode contact surface, destroying vacuum adsorption and electrostatic interaction, and improving separation efficiency by more than 90%.

[0042] Optimized adsorption performance: The design of the U-shaped adsorption groove and connecting groove expands the adsorption contact area and improves the uniformity of adsorption force by 40%; the integrated structure of the suction plate body and the mounting base reduces the risk of gas leakage and improves vacuum stability.

[0043] Compatibility and scalability: Adaptable to various electrode sizes and vehicle models (such as blade batteries and range-extended hybrid vehicles); modular design supports integration with other production equipment (such as CTP / CTB battery pack production lines).

[0044] Economic benefits: Reduces downtime caused by conveyor belts, improves yield rate; reduces material costs by 25% (compared to traditional metal suction plates).

[0045] The embodiments described in this utility model are for illustrative purposes only and do not constitute a limitation on the scope of the claims. Other substantially equivalent substitutions that can be conceived by those skilled in the art are all within the protection scope of this utility model.
