Description

Technical Field

[0001] This invention relates to the field of battery manufacturing technology, and more specifically, to a dust removal device and method for inserting square battery cells into the casing. Background Technology

[0002] In the battery manufacturing process, installing the battery cells into the casing (i.e., casing installation) is a crucial step, followed by welding. During transportation and storage, the battery cells and casing easily attract dust, fiber debris, and other impurities; therefore, dust removal is necessary before casing installation. Residual dust after casing can cause internal short circuits, increased self-discharge, and welding defects such as incomplete or missing welds, directly impacting battery performance and lifespan.

[0003] However, currently, the casing and the battery cell share the same dust removal mechanism, which cannot differentiate dust removal, and the dust removal coverage is incomplete, resulting in poor dust removal effect on the battery cell and casing. Furthermore, in the casing process, the traditional method is to fix the casing and then push the battery cell directly into the casing in one go. This method is very likely to cause friction and scraping between the side wall of the battery cell and the edge of the casing, or cause wrinkles in the battery cell separator and misalignment of the electrode due to excessive resistance, resulting in an increase in the defect rate.

[0004] Therefore, it is necessary to provide a dust removal device and method for inserting square battery cells into the casing to solve the above-mentioned technical problems. Summary of the Invention

[0005] The purpose of this invention is to provide a dust removal device and method for inserting square battery cells into the casing to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A dust removal device for square battery cells, comprising: The shell dust removal mechanism is used to support the shell body and remove dust from it; The cell dust removal mechanism is used to support the cell body and remove dust from it; A fixing mechanism is used to receive and fix the shell body after dust removal, and exposes one open end of the shell body. The insertion mechanism, arranged opposite to the fixing mechanism, is used to receive the battery cell body after dust removal and to feed the battery cell body into the housing body in a stepping manner.

[0007] Furthermore, the housing mechanism includes: The positioning component, which supports the battery cell body, is used to position and clamp the left and right sides of the battery cell body. A clamping component is disposed between the positioning component and the fixing mechanism to clamp the upper and lower ends of the battery cell body and drive it to move into the casing; The moving component is used to drive the positioning component and the clamping component to move towards and away from the housing body, respectively.

[0008] Furthermore, the positioning component includes a liftable positioning platform and clamping members disposed on the left and right sides of the positioning platform, the clamping members being used to clamp the left and right sides of the battery cell body. The clamping component includes a lower clamp and an upper clamp, both of which can be raised and lowered; The positioning platform has an clearance opening adapted to the lower clamp; the lower clamp cooperates with the upper clamp to clamp the upper and lower sides of the battery cell body.

[0009] Furthermore, the housing dust removal mechanism is provided with at least one component, the housing dust removal mechanism comprising: The receiving frame is used to support and limit the position of the housing body; An air blowing nozzle is located at one end of the receiving frame and is used to blow air into the inner cavity of the housing body from one end; A suction bucket, located at the other end of the receiving frame and corresponding to the blowing nozzle, is used to vacuum dust from the other end of the housing body.

[0010] Furthermore, the cell dust removal mechanism is provided with at least one component, the cell dust removal mechanism comprising: The dust removal component can be raised and lowered, and after being lowered, it can cover the outside of the battery cell body below, and remove dust by blowing air and sucking air into the battery cell body. A support plate supports at least one battery cell body. The bottom of the support plate is hollowed out at the position corresponding to the position of the battery cell body. The support plate is used to move the battery cell body to the bottom of the dust removal component.

[0011] Furthermore, the dust removal component includes a dust suction hood and an air inlet pipe and an air extraction pipe disposed on the dust suction hood. When the dust suction hood is lowered into position, it will cover the outside of the battery cell body below. The air inlet pipe and the air extraction pipe are used to blow air and suck air into the dust suction hood, respectively.

[0012] Furthermore, it also includes a conveyor line for receiving the dust-treated housing body and conveying it to the fixing mechanism, the fixing mechanism comprising: The first fixing component is located on one side of the housing body and is arranged on the side close to the clamping component, and is used to limit the periphery of one end of the housing body. The second fixing component is located on the other side of the housing body and is arranged on the side away from the clamping component, for clamping the other end of the housing body.

[0013] Furthermore, the first fixing component includes a first pressing component that presses down and fixes one end of the top of the housing body, and a locking component that engages around the perimeter of the end of the housing body. The second fixing component includes a second pressing assembly that presses down and fixes the other end of the top of the housing body, and a clamping member that tightens the other end of the housing body.

[0014] Furthermore, a detection component and a defective product line are provided between the cell dust removal mechanism and the casing insertion mechanism. The detection component is used to detect the cell body, and unqualified cell bodies flow into the defective product line.

[0015] A method for inserting a square battery cell into a casing dust removal device, using the aforementioned square battery cell casing dust removal device, specifically includes the following steps: S1. The dust-removed housing body is transported to the fixing mechanism. At the same time, the dust-removed battery cell body is transferred to the positioning platform. Its left and right sides are clamped and fixed by clamping parts. The moving part drives the positioning platform to move towards the clamping part to the housing preparation position. S2. At this time, the clamping component is in the clamping position. The lower clamping part moves up and extends into the clearance opening to support the battery cell body from the bottom. At the same time, the upper clamping part moves down and works with the lower clamping part to clamp the battery cell body from the top and bottom sides. S3. The clamping component releases the battery cell body, the positioning platform descends to avoid the battery cell body, and the moving component drives the clamping component forward to the housing position, so that the front end of the battery cell body extends into the housing body. S4. The positioning platform rises to support the battery cell body and clamps it with the clamping component. The clamping component releases the battery cell body and retracts to the clamping position through the moving component. S5. The clamping component clamps the battery cell body again from the top and bottom sides. The clamping component releases the battery cell body and lowers to avoid the position. The clamping component moves forward again to the housing position and pushes the battery cell body into the housing body. S6. Repeat steps S3-S5 above, pushing the battery cell segment by segment to complete the step-by-step casing installation.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. This invention abandons the traditional industry method of forcefully pushing the battery cell body into the casing in one go. This casing insertion mechanism replaces the traditional hard push casing insertion with step-by-step casing insertion. The positioning component and clamping component alternately clamp the battery cell body to achieve segmented step-by-step casing insertion. The single push stroke is short and the casing insertion resistance is gentle. It avoids hard friction and scraping between the battery cell sidewall and the edge of the casing opening, and it will not cause irreversible internal damage such as cell diaphragm wrinkles and electrode misalignment due to instantaneous extrusion force. It significantly reduces the scrap rate of the casing insertion process and improves the yield rate of the production line.

[0017] 2. The dust removal mechanism for the casing and the dust removal mechanism for the battery cell are independently set up in this invention, respectively completing independent and dedicated dust removal operations for the casing body and the battery cell body. The casing body adopts a through-type dust removal method with air blowing at one end and dust extraction at the other end to clean internal impurities; the battery cell body adopts a closed-hood type blowing and suction dust removal method, combined with a bottom hollow structure to achieve all-round dust removal. The two operate independently without interference, and the dust removal coverage is comprehensive, effectively avoiding problems such as battery short circuits, self-discharge, and poor welding caused by dust residue, significantly improving battery life and service life.

[0018] 3. The fixing mechanism of the present invention uses the circumferential limiting of the locking part and the axial pressing of the pressing part, combined with the bidirectional pressing of the top of the first pressing component and the second pressing component, to achieve all-directional positioning and locking of the shell body after dust removal, which greatly ensures that the shell does not move or shift during the entire process of entering the shell.

[0021] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Please see Figure 1-6 A dust removal device for square battery cells, comprising: The shell dust removal mechanism 3 is used to support the shell body 1 and remove dust from it; The cell dust removal mechanism 4 is used to support the cell body 2 and remove dust from it; The fixing mechanism 5 is used to receive and fix the shell body 1 after dust removal, and exposes one open end of the shell body 1. The insertion mechanism 6 is arranged opposite to the fixing mechanism 5. It is used to receive the battery cell body 2 after dust removal and to send the battery cell body 2 into the housing body 1 in a stepping manner.

[0023] The housing body 1 is received by the housing dust removal mechanism 3 and its internal cavity is cleaned. Simultaneously, the battery cell dust removal mechanism 4 receives the battery cell body 2 and its surface is cleaned. The cleaned housing body 1 is then moved to the fixing mechanism 5 for positioning and fixing, exposing the open end. Simultaneously, the cleaned battery cell body 2 is moved to the loading position of the housing insertion mechanism 6. Finally, the housing insertion mechanism 6 smoothly and gradually pushes the battery cell body 2 into the housing body 1 in a stepping manner, completing the housing assembly.

[0024] The casing dust removal mechanism 3 and the cell dust removal mechanism 4 are set up independently to complete the independent dust removal operation of the casing body 1 and the cell body 2 respectively. They can match exclusive dust removal solutions according to the structural characteristics of the casing body 1 and the cell body 2. The cleanliness is much higher than that of the shared dust removal mode. The two dust removal systems operate independently and do not interfere with each other, eliminating dust residue from the source and effectively avoiding battery defects such as internal short circuits, excessive self-discharge, and poor welding of the cell body 2.

[0025] Abandoning the industry's traditional method of forcefully pushing the battery cell body 2 into the casing in one go, this casing insertion mechanism 6 replaces the traditional hard push method by stepping into the casing. This avoids hard friction and scraping between the side wall of the battery cell body 2 and the edge of the casing opening, and also prevents irreversible internal damage such as diaphragm wrinkles and electrode misalignment of the battery cell body 2 caused by instantaneous extrusion pressure. This significantly reduces the scrap rate of the casing insertion process and improves the yield rate of the production line.

[0026] Preferably, the housing mechanism 6 includes: Positioning component 61, on which the battery cell body 2 is supported, is used to position and clamp the left and right sides of the battery cell body 2. The clamping component 62 is located between the positioning component 61 and the fixing mechanism 5, and is used to clamp the upper and lower ends of the battery cell body 2 and drive it to move into the casing. The moving component is used to drive the positioning component 61 and the clamping component 62 to move towards and away from the housing body 1, respectively. The moving component can be in the form of a linear module, cylinder drive, etc.

[0027] During operation, after the dust removal process, the battery cell body 2 is transferred to the positioning component 61, which clamps the battery cell from both sides. Then, the moving component drives the positioning component 61 to move towards the clamping component 62 to the housing preparation position. Initially, the clamping component 62 is in the clamping position. Then, the clamping component 62 moves to clamp the part of the battery cell body 2 exposed outside the housing body 1 from the top and bottom. The positioning component 61 releases its position simultaneously, and the moving component drives the clamping component 62 to move forward to the housing position, so that the front end of the battery cell body 2 extends into the housing body 1. Then, the positioning component 61 clamps the battery cell body 2, the clamping component 62 releases, and the moving component drives the clamping component 62 back to the clamping position. Then, the clamping component 62 clamps the battery cell body 2 again, the positioning component 61 releases and moves away, and the moving component drives the clamping component 62 to push the battery cell body 2 forward again. By repeating the above actions, the battery cell body 2 can be gradually and completely sent into the housing body 1.

[0028] By alternately clamping the battery cell body 2 with the positioning component 61 and the clamping component 62, segmented step-by-step insertion into the casing is achieved. The single push stroke is short and the insertion resistance is gentle, which can avoid hard friction and scraping between the battery cell body 2 and the opening edge of the casing body 1, and will not cause internal damage such as cell diaphragm wrinkles or electrode misalignment due to excessive instantaneous thrust. This greatly reduces the defect rate of the insertion process and improves the battery cell assembly quality.

[0029] Preferably, the positioning component 61 includes a liftable positioning platform 611 and clamping members 612 disposed on the left and right sides of the positioning platform 611. The clamping members 612 are used to clamp the left and right sides of the battery cell body 2. The clamping component 62 includes a lower clamp 621 and an upper clamp 622, both of which can be raised and lowered. The positioning platform 611 has an avoidance opening 613 that is adapted to the lower clamp 621; the lower clamp 621 cooperates with the upper clamp 622 to clamp the upper and lower sides of the battery cell body 2.

[0030] After dust removal, the battery cell body 2 is transferred to the support surface of the positioning platform 611. The clamping parts 612 on both sides move towards each other and clamp the battery cell body 2 from the left and right sides. After the positioning platform 611 and the battery cell body 2 are moved to the housing preparation position by the moving parts, the lower clamping part 621 of the positioning part 61 is raised upward and extends into the clearance opening 613 at the front end of the positioning platform 611 to support the battery cell body 2 from the bottom. At the same time, the upper clamping part 622 moves downward and cooperates with the lower clamping part 621 to clamp the battery cell body 2 from the upper and lower sides. Subsequently, the clamping member 612 is released and the positioning platform 611 moves down to avoid a misalignment, thus detaching from the battery cell body 2. Then, the clamping component 62 moves to push the battery cell body 2 into the casing. Then, the positioning platform 611 rises and clamps the battery cell body 2 through the clamping member 612. The upper clamping member 622 rises and releases, the lower clamping member 621 descends, and the clamping component 62 retracts to the clamping position and clamps the battery cell body 2 again. The positioning component 61 is released and moves down to avoid a misalignment, and the clamping component 62 can continue the next round of pushing.

[0031] Preferably, at least one dust removal mechanism 3 for the housing is provided, and the dust removal mechanism 3 for the housing includes: The receiving frame 31 is used to receive the housing body 1 and limit its position; An air blowing nozzle 32 is located at one end of the receiving frame 31 and is used to blow air into the inner cavity of the housing body 1 from one end. The air nozzle 32 is aligned with the opening at one end of the housing body 1 and is connected to an external clean compressed air source. The suction bucket 33 is located at the other end of the receiving frame 31 and corresponds to the blowing nozzle 32. The air inlet of the suction bucket 33 is aligned with the opening at the other end of the housing body 1. The suction bucket 33 is connected to a negative pressure dust collection system for dust collection from the other end of the housing body 1.

[0032] The housing body 1 to be dusted is transferred to the receiving frame 31, which circumferentially limits the housing body 1. Then, the air blowing nozzle 32 at one end of the receiving frame 31 is activated to blow high-pressure gas into the inner cavity of the housing body 1, blowing away the dust and fiber debris attached to the inner wall. At the same time, the suction bucket 33 at the other end of the receiving frame 31 is activated to simultaneously suck out the dust and debris inside the housing body 1 through negative pressure, thus completing the dust removal inside the housing body 1.

[0033] By adopting a through-flow dust removal solution that blows air at one end and extracts dust at the other end, it perfectly matches the structural characteristics of the shell body 1, and can achieve thorough cleaning of the inner cavity of the shell body 1 without dead corners, resulting in thorough and efficient dust removal; multiple sets of shell dust removal mechanisms 3 can be set up to operate in parallel, flexibly matching different production capacity requirements.

[0034] Preferably, at least one cell dust removal mechanism 4 is provided, and the cell dust removal mechanism 4 includes: The dust removal component 41 can be lifted and moved, and after being lowered, it can cover the outside of the battery cell body 2 below, and remove dust by blowing air and sucking air onto the battery cell body 2. The support plate 42 supports at least one battery cell body 2. The bottom of the support plate 42 is hollowed out at the position corresponding to the position of the battery cell body 2, so that airflow can pass through the upper and lower surfaces of the battery cell, making it easier for dust to be discharged from the bottom and for more comprehensive dust removal. The support plate 42 is used to move the battery cell body 2 to the bottom of the dust removal component 41.

[0035] The bottom of the receiving plate 42 is provided with a moving part, which can be in the form of a linear module, cylinder drive, etc.

[0036] Specifically, the battery cell body 2 to be dusted is moved onto the carrier plate 42; then the carrier plate 42 moves horizontally, conveying the battery cell body 2 directly below the dust removal component 41; then the dust removal component 41 is controlled to descend and cover the battery cell body 2, blowing air and simultaneously sucking air, and with the hollow structure at the bottom of the carrier plate 42, the airflow passes through the bottom of the battery cell body 2 to complete all-round dust removal; after the dust removal is completed, the dust removal component 41 rises and resets, the carrier plate 42 moves out of the dust removal position, and the material is discharged.

[0037] Preferably, the carrier plate 42 is provided with two sets of positioning members for positioning and clamping the battery cell body 2. The two sets of positioning members can move toward each other or away from each other.

[0038] After the battery cell body 2 is transferred to the carrier plate 42, the two sets of positioning components are driven to move towards each other and clamp the battery cell body 2 from both sides, thus completing the positioning and fixing of the battery cell body 2 on the carrier plate 42 and ensuring the stability of the battery cell body 2 during the dust removal process. After the dust removal is completed, the two sets of positioning components move away from each other to release the battery cell body 2, and then the material can be unloaded and transferred.

[0039] Preferably, the dust removal component 41 includes a dust suction hood 411 and an air inlet pipe 412 and an air extraction pipe 413 disposed on the dust suction hood 411. When the dust suction hood 411 is lowered into position, it will cover the outside of the battery cell body 2 below. The air inlet pipe 412 and the air extraction pipe 413 are used to blow air and extract air into the dust suction hood 411, respectively.

[0040] With this design, when the carrier plate 42 moves the battery cell body 2 to directly below the dust collection hood 411, it drives the dust collection hood 411 to descend, covering the outside of the battery cell body 2 to form a closed dust removal space; then clean high-pressure gas is introduced into the dust collection hood 411 through the air inlet pipe 412 to blow away the dust on the surface of the battery cell body 2, and at the same time, air is drawn out through the air extraction pipe 413 to simultaneously discharge the raised dust from the hood, thus completing the dust removal of the battery cell body 2.

[0041] After the dust hood 411 descends, it forms a closed dust removal space, preventing dust from spreading outward and polluting the workshop environment. At the same time, it ensures stable internal airflow and uniform blowing force. In conjunction with the formation of circulating airflow, it can quickly remove dust and debris from the surface of the battery cell body 2, resulting in high dust removal efficiency and good cleanliness.

[0042] In this embodiment, a conveyor line is also included. The conveyor line is used to receive the dust-removed housing body 1 and transport the housing body 1 to the fixing mechanism 5. The fixing mechanism 5 includes: The first fixing component 51 is located on one side of the housing body 1 and is arranged on the side close to the clamping component 62, and is used to limit the periphery of one side end of the housing body 1. The second fixing component 52 is located on the other side of the housing body 1 and is arranged on the side away from the clamping component 62, and is used to tighten the other end of the housing body 1.

[0043] After the shell body 1 has been dusted, it is automatically transported by the conveyor line to the station of the fixing mechanism 5. Then, the first fixing component 51 on the side closer to the shell insertion mechanism 6 limits the opening end of the shell body 1 around, and the second fixing component 52 on the side away from the shell insertion mechanism 6 axially tightens the other end of the shell body 1. The positioning of the shell body 1 is completed from both ends, waiting for the shell insertion operation.

[0044] The conveyor line enables the automatic transfer of the shell body 1 after dust removal, eliminating the need for manual transfer and improving the automation level of the production line; the first fixing component 51 and the second fixing component 52 respectively limit and tighten the two ends of the shell body 1, so that the shell will not move during the shell insertion process, ensuring the accuracy of the shell insertion depth and improving the consistency of assembly.

[0045] In this embodiment, the first fixing component 51 includes a first pressing component 511 that presses down and fixes one end of the top of the housing body 1 and a locking component 512 that engages the periphery of the end of the housing body 1. The second fixing component 52 includes a second pressing assembly 521 that presses down and fixes the other end of the top of the housing body 1, and a clamping member 522 that tightens the other end of the housing body 1.

[0046] After the housing body 1 is delivered to the position, it is first engaged with the outer periphery of the opening end of the housing body 1 by the engaging member 512 to limit the offset of the housing body 1. At the same time, the first pressing component 511 descends and presses the opening end of the housing from the top. Then, the pressing member 522 extends forward and presses the other end of the housing. At the same time, the second pressing component 521 descends and presses the other end of the housing from the top. The two ends are pressed synchronously from top to bottom to complete the omnidirectional fixation of the housing.

[0047] In this embodiment, a detection component 7 and a defective product line 8 are provided between the cell dust removal mechanism 4 and the casing insertion mechanism 6. The detection component 7 is used to detect the cell body 2 in the cell dust removal mechanism 4. The unqualified cell body 2 flows into the defective product line 8. The detection component 7 can be a visual inspection device, a cleanliness inspection device, etc.

[0048] After the cell body 2 is cleaned of dust, the detection component 7 detects the appearance, size, surface cleanliness, etc. of the cell body 2. The qualified cell body 2 is transferred to the casing mechanism 6 for casing operation, while the unqualified cell body 2 is directly diverted to the defective product line 8 and automatically discharged from the production line.

[0049] Substandard battery cells can be removed in advance to prevent defective products from flowing into the next process and reduce the ineffective costs of subsequent welding and assembly. Combined with the automatic diversion of defective products line 8, manual sorting is not required, which improves the automation level of the production line and the product yield control level.

[0050] In this embodiment, a gantry frame 10 is also included, on which at least one picking and placing mechanism 9 is provided for picking up the battery cell body 2 and placing it successively at the battery cell dust removal mechanism 4 and the casing mechanism 6.

[0051] When the battery cell body 2 is transferred, the pick-and-place mechanism 9 on the gantry frame 10 is first driven to move to the loading position and grab the battery cell body 2; then the battery cell body 2 is moved to the battery cell dust removal mechanism 4 and placed on the carrier plate 42; after the dust removal is completed, the pick-and-place mechanism 9 grabs the battery cell body 2 again and transfers it to the positioning component 61 of the housing mechanism 6 to complete the inter-process transfer.

[0052] By using the gantry frame 10 in conjunction with the pick-and-place mechanism 9, the battery cell body 2 can be automatically transferred between multiple workstations, replacing manual loading and unloading, improving production efficiency, and reducing secondary dust pollution caused by manual contact; multiple pick-and-place mechanisms 9 can be configured to operate in parallel to match the transfer of multi-workstation production lines.

[0053] The present invention also provides a method for inserting a square battery cell into a casing dust removal device, which specifically includes the following steps: S1. The dust-removed housing body 1 is transported to the fixing mechanism 5. At the same time, the dust-removed battery cell body 2 is transferred to the positioning platform 611. Its left and right sides are clamped and fixed by the clamping parts 612. The moving part drives the positioning platform 611 to move towards the clamping part 62 to the housing preparation position. S2. At this time, the clamping component 62 is in the clamping position, the lower clamp 621 moves upward and extends into the clearance opening 613 to support the battery cell body 2 from the bottom, and at the same time the upper clamp 622 moves downward to cooperate with the lower clamp 621 to clamp the battery cell body 2 from the upper and lower sides. S3. The clamping member 612 releases the battery cell body 2, the positioning platform 611 descends to avoid the battery cell body 2, and the moving part drives the clamping member 62 to move forward to the housing position, so that the front end of the battery cell body 2 extends into the housing body 1. S4. The positioning platform 611 rises to support the battery cell body 2 and clamps it through the clamping member 612. The clamping member 62 releases the battery cell body 2 and retracts to the clamping position through the moving member. S5. The clamping component 62 clamps the battery cell body 2 again from the upper and lower sides. The clamping component 612 releases the battery cell body 2 and lowers to avoid the position. The clamping component 62 moves forward again to the housing position and pushes the battery cell body 2 into the housing body 1. S6. Repeat steps S3-S5 above, pushing segment by segment to complete the step-by-step casing insertion operation of the battery cell body 2.
