Description

Technical Field

[0001] This invention belongs to the technical field of automated lithium battery production equipment, and in particular relates to a welding equipment for explosion-proof aluminum shell sheets of new energy batteries. Background Technology

[0002] With the rapid development of new energy battery technology, the safety and production efficiency of battery structure have become the focus of industry attention. Square aluminum-cased lithium batteries usually need to have pre-drilled holes on the top of the casing to install explosion-proof plates in order to release pressure when the internal pressure of the battery is too high.

[0003] In existing assembly and welding processes for explosion-proof sheets and aluminum shells, a high-speed chain or conveyor belt is typically used in conjunction with tooling fixtures for transfer. This involves placing the aluminum shell in a fixture, which then moves along the production line through various workstations. However, this process has the following drawbacks: The setup of multiple fixtures during long-distance, multi-station flow can easily lead to a decrease in the positioning accuracy of the aluminum shell at the welding station due to frequent positioning, wear and tear, and the manufacturing tolerances of the fixtures themselves, thus affecting the focus alignment of laser welding. When producing battery aluminum casings of different sizes, it is often necessary to change all the tooling and fixtures on the entire production line, resulting in a long debugging cycle and poor production flexibility. Explosion-proof sheets are usually thin, and the incoming material may have slight deformation. Existing technology often directly picks up the explosion-proof sheet and places it for welding, resulting in poor adhesion between the explosion-proof sheet and the aluminum shell. During laser welding, problems such as sparking, incomplete welding or substandard sealing are prone to occur. Therefore, there is an urgent need for an automated device that can solve the above-mentioned defects. Summary of the Invention

[0004] The purpose of this invention is to provide a welding equipment for explosion-proof aluminum shells of new energy batteries, in order to solve the problems of decreased positioning accuracy of aluminum shells at the welding station, long debugging cycle, and poor production flexibility.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A welding device for explosion-proof aluminum shell sheets of new energy batteries includes a cabinet platform. An aluminum shell feeding assembly is provided on one side of the cabinet platform. The aluminum shell feeding assembly's discharge end is equipped with an aluminum shell alignment assembly and a marking assembly. The device also includes: An explosion-proof assembly assembly is connected to the rear side of the stroke of the corresponding marking assembly at the top of the cabinet platform. The aluminum shell alignment assembly, explosion-proof assembly assembly, marking assembly and aluminum shell feeding assembly are arranged sequentially at intervals along the length of the cabinet platform. The product handling component is located on one side of the explosion-proof sheet assembly component. The product handling component is used to transfer the aluminum shell back and forth between the aluminum shell alignment component, the marking component, the explosion-proof sheet assembly component and the aluminum shell feeding component. An explosion-proof sheet feeding assembly is connected to the top of the cabinet platform on the side away from the product handling assembly. The explosion-proof sheet is output to the assembly station of the explosion-proof sheet assembly assembly through the explosion-proof sheet feeding assembly. The explosion-proof sheet welding assembly and the inspection and unloading assembly are arranged sequentially and at intervals along the length of the cabinet platform at the top of the cabinet platform, located behind the explosion-proof sheet assembly assembly. They are used to weld the assembled explosion-proof sheet and aluminum shell and to perform visual inspection.

[0006] As a further description of the above technical solution: The explosion-proof sheet feeding assembly includes: A rotary station is located on the top side of the cabinet platform. The rotary station is configured to rotate and drive multiple explosion-proof sheets for feeding, shaping and error-proof detection. An explosion-proof clip is located on the top of the cabinet platform, on one side of the corresponding rotary station feeding station. The explosion-proof clip contains multiple explosion-proof clips for limiting movement. An explosion-proof sheet shaping unit is located on the top of the cabinet platform, adjacent to the feeding station of the rotating station. The explosion-proof sheet is fed into the bottom of the explosion-proof sheet shaping unit through the rotating station. The explosion-proof sheet shaping unit includes a shaping cylinder. The moving end of the shaping cylinder is connected to a shaping pressure plate. The moving end of the shaping cylinder moves to drive the shaping pressure plate to press and shape the explosion-proof sheet at the top of the rotating station. The front and back error-proof detection unit is located on the opposite side of the material feeding station at the top of the cabinet platform, and is configured to visually inspect the front and back of the explosion-proof sheet after pressing and shaping. The assembly and feeding unit is located on the top of the cabinet platform, near the side of the explosion-proof sheet assembly assembly, and is used to output the explosion-proof sheet to the assembly station of the explosion-proof sheet assembly assembly assembly.

[0007] As a further description of the above technical solution: The assembly and loading unit includes: The assembly and feeding linear module is connected to a telescopic cylinder at its movable end, and a transfer suction cup at its movable end. The transfer suction cup is used to pick up and output the explosion-proof sheet from the rotary station unloading station to the assembly station of the explosion-proof sheet assembly components.

[0008] As a further description of the above technical solution: The assembly and loading unit also includes: The forward and reverse feeding unit is located on the top of the cabinet platform, near the forward and reverse error-proof detection unit. The forward and reverse feeding unit includes a linearly moving forward and reverse feeding suction cup, which removes misaligned explosion-proof sheets.

[0009] As a further description of the above technical solution: The assembly and feeding unit further includes: a first linear module connected to the top of the cabinet platform, and a gripping unit connected to the movable end of the first linear module, which transports the explosion-proof discs in the explosion-proof disc clip to the top of the corresponding feeding station on one side of the rotating station through the gripping unit.

[0010] As a further description of the above technical solution: The explosion-proof assembly includes: The lifting cylinder is installed on the top of the cabinet platform. Assemble the pressure plate and connect it to one end of the movable end of the lifting cylinder. The explosion-proof plate is pressed into the explosion-proof valve hole on the top of the aluminum shell by extending and retracting the movable end of the lifting cylinder.

[0011] As a further description of the above technical solution: The product handling components include: The base plate is connected to one side of the cabinet platform. The top of the base plate is provided with an X-axis linear module. The movable end of the X-axis linear module is connected to a Y-axis linear module. The movable end of the Y-axis linear module is connected to a transport frame. Multiple parallel clamping cylinders are arranged in an array along the length direction on the front side of the transport frame. The movable end of the parallel clamping cylinder is connected to a clamping finger. The aluminum shell is clamped and limited by the clamping fingers on both sides approaching each other.

[0012] As a further description of the above technical solution: The explosion-proof sheet welding assembly includes a laser welding device, a jig core, and a welding pressure plate. The jig core is connected to the top of the cabinet platform, and a welding lifting cylinder is connected to the bottom of the welding pressure plate. When the aluminum shell is placed in the welding station, the jig core moves into the inner cavity of the aluminum shell. At this time, the welding lifting cylinder controls the welding pressure plate to press down and position the aluminum shell. At this time, the top laser welding device can weld the explosion-proof sheet to the top of the aluminum shell.

By fixing the workstation fixture and moving the product, the mechanical wear and cumulative errors caused by repeated transfer of the fixture are eliminated, ensuring that the aluminum shell is always positioned with high precision in each stage of marking, assembly and welding, and improving the alignment accuracy of subsequent laser welding.

[0016] 2. In this invention, by setting up an explosion-proof sheet feeding assembly that includes a rotating station, an explosion-proof sheet shaping unit, and a forward and reverse error-proof detection unit, the explosion-proof sheet is first pressed, shaped, and visually inspected before being assembled into the housing. This design effectively solves the problem of uneven incoming explosion-proof sheets, ensuring a tight fit between the explosion-proof sheet and the aluminum shell, thereby avoiding laser welding leaks or defects caused by excessive gaps, and improving the airtightness and safety of the product.

[0017] 3. In this invention, by designing aluminum shell alignment components and product handling components, when switching between different specifications of aluminum shell products, only the finger spacing, the stroke of the alignment mechanism, or the simple positioning module needs to be adjusted. There is no need to replace the entire production line's transfer fixtures on a large scale, which shortens the changeover and debugging time, improves production efficiency, and integrates the entire set of processes such as aluminum shell feeding, alignment, coding, explosion-proof sheet shaping and feeding, assembly, welding, and inspection and unloading on the same cabinet platform. The process flow is continuous, the space utilization rate is high, and the explosion-proof sheet sealing operation is fully automated on a single machine. Attached Figure Description

Detailed Implementation

[0020] 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.

[0021] Please see Figures 1-7 The present invention provides a technical solution: a welding equipment for aluminum shell explosion-proof sheet of new energy battery, including a cabinet platform 1, an aluminum shell feeding component 3 is provided on one side of the cabinet platform 1, and a marking component 5 is provided at the discharge end of the aluminum shell feeding component 3. Also includes: The explosion-proof assembly component 7 is connected to the rear side of the stroke of the marking component 5 at the top of the cabinet platform 1. The aluminum shell alignment component 4, the explosion-proof assembly component 7, the marking component 5 and the aluminum shell feeding component 3 are arranged in sequence at intervals along the length of the cabinet platform 1. Product handling component 6 is located on one side of explosion-proof sheet assembly component 7. The product handling component 6 is used to transfer the aluminum shell back and forth between aluminum shell alignment component 4, marking component 5, explosion-proof sheet assembly component 7 and aluminum shell feeding component 3. The explosion-proof sheet feeding assembly 2 is connected to the top of the cabinet platform 1 on the side away from the product handling assembly 6. The explosion-proof sheet is output to the assembly station of the explosion-proof sheet assembly assembly 7 through the explosion-proof sheet feeding assembly 2. The explosion-proof sheet welding assembly 8 and the inspection and unloading assembly 9 are arranged sequentially and at intervals along the length of the cabinet platform 1 at the top of the cabinet platform 1, located behind the explosion-proof sheet assembly assembly 7. They are used to weld the assembled explosion-proof sheet and aluminum shell and to perform visual inspection. Specifically, the designed product handling component 6 can transfer the aluminum shell to be welded between the marking, assembly, welding and inspection stations. By transferring the aluminum shell, the tooling fixture is kept in its original position, reducing the high-frequency error of transferring multiple tooling fixtures. Furthermore, by changing the corresponding tooling fixture, the process of switching aluminum shell size can be quickly matched, thereby improving production efficiency.

[0022] Furthermore, it also includes: a discharge assembly 10, connected to the side of the cabinet platform 1 away from the product handling assembly 6, through which the visually inspected aluminum shells are discharged. The discharge assembly 10 includes two sets of conveyor belts and a gripping mechanism that moves between the two sets of conveyor belts and the inspection and unloading assembly 9, for separating the qualified and unqualified aluminum shells after visual inspection for separate discharge. The conveyor belts are conveyor belts with grid clamps. This part is a mature technology in related fields and should not be regarded as a limitation on the embodiments of this application. Explosion-proof sheet feeding assembly 2 includes: Rotary station 207 is located on the top side of cabinet platform 1. Rotary station 207 is configured to rotate and drive multiple explosion-proof sheets for feeding, shaping and forward / backward error-proof detection. An explosion-proof clip 201 is located on the top of the cabinet platform 1, corresponding to the feeding station of the rotating station 207 on one side. Multiple explosion-proof clips are limited inside the explosion-proof clip 201. The explosion-proof sheet shaping unit 202 is located on the top of the cabinet platform 1, adjacent to the feeding station of the rotating station 207. The explosion-proof sheet is fed into the bottom of the explosion-proof sheet shaping unit 202 through the rotating station 207. The explosion-proof sheet shaping unit 202 includes a shaping cylinder. The moving end of the shaping cylinder is connected to a shaping pressure plate. The moving end of the shaping cylinder drives the shaping pressure plate to press and shape the explosion-proof sheet at the top of the rotating station. The front and back error-proof detection unit 203 is located on the top of the cabinet platform 1, opposite to the feeding station of the rotating station 207, and is configured to visually inspect the front and back of the explosion-proof sheet after pressing and shaping. The assembly and feeding unit 204 is located on the top of the cabinet platform 1, near the side of the explosion-proof sheet assembly component 7. The assembly and feeding unit 204 includes an assembly and feeding linear module. The movable end of the assembly and feeding linear module is connected to a telescopic cylinder. The movable end of the telescopic cylinder is connected to a transport suction cup. The explosion-proof sheet from the unloading station of the rotary station 207 is picked up and output to the assembly station of the explosion-proof sheet assembly component 7 through the transport suction cup. Specifically: The explosion-proof sheet feeding component 2 is designed to enable the feeding, shaping, error prevention and assembly of explosion-proof sheets through the rotating station 207. The station flow provides continuous processing efficiency, and the pre-pressing and shaping of the explosion-proof sheets reduces the omissions and mis-welding between the explosion-proof sheets and the aluminum shell due to the error of the explosion-proof sheets, improves the feeding and assembly accuracy of the explosion-proof sheets, and is beneficial for subsequent laser welding.

[0023] Furthermore, through the designed assembly and feeding unit 204, the movable end can be extended by the operation of the telescopic cylinder to make the transport suction cup fit with the explosion-proof sheet. After the explosion-proof sheet is adsorbed by the transport suction cup, the telescopic cylinder works to reset and avoid the movement path. After the explosion-proof sheet is adsorbed, it moves linearly to the assembly station through the assembly and feeding linear module. At this time, the telescopic cylinder extends and places it on the top of the aluminum shell after the explosion-proof sheet assembly component 7 is limited. Also includes: The forward and reverse feeding unit 208 is located on the top of the cabinet platform 1, near the forward and reverse error prevention detection unit 203. The forward and reverse feeding unit 208 includes a linearly moving forward and reverse feeding suction cup, which removes misaligned explosion-proof sheets. It also includes: a first linear module 205, which is connected to the top of the cabinet platform 1, and the movable end of the first linear module 205 is connected to a gripping unit 206, which transports the explosion-proof disc in the explosion-proof disc clip 201 to the top of the corresponding feeding station on one side of the rotary station 207 through the gripping unit 206.

[0024] Explosion-proof assembly component 7 includes: Lifting cylinder 701 is installed on the top of the cabinet platform 1; Assemble the pressure plate 702 and connect it to one end of the movable end of the lifting cylinder 701. Press the explosion-proof sheet into the explosion-proof valve hole on the top of the aluminum shell by extending and retracting the movable end of the lifting cylinder 701. After the aluminum shell is engraved and transported to the assembly station by the product handling component 6, it can be placed at the bottom of the assembly plate 702. When the explosion-proof plate feeding component 2 feeds the explosion-proof plate into the bottom side of the assembly plate 702 and resets and retracts, the lifting cylinder 701 can work to shorten and drive the assembly plate 702 to press the explosion-proof plate into the explosion-proof hole reserved on the surface of the aluminum shell to complete the initial pressing. The inspection and unloading component 9 includes a detection CCD, which uses visual recognition to determine the welding area; Product handling assembly 6 includes: a base plate 601 connected to one side of the cabinet platform 1; an X-axis linear module 602 is provided on the top of the base plate 601; a Y-axis linear module 603 is connected to the movable end of the X-axis linear module 602; a handling frame 604 is connected to the movable end of the Y-axis linear module 603; a plurality of parallel clamping cylinders 605 are arranged in an array along the length direction on the front side of the handling frame 604; clamping fingers 606 are connected to the movable ends of the parallel clamping cylinders 605; the aluminum shell is clamped and limited by the clamping fingers 606 on both sides approaching each other.

[0025] The explosion-proof sheet welding assembly 8 includes a laser welding device, a jig core, and a welding pressure plate. The jig core is connected to the top of the cabinet platform 1. A lifting assembly is connected to the bottom of the welding pressure plate. The lifting assembly is connected to the top of the cabinet platform 1. The welding pressure plate is located on top of the jig core. The laser welding device is located on top of the welding pressure plate. When the jig core moves into the inner cavity of the aluminum shell, the welding pressure plate presses down to position the aluminum shell, and the laser welding device welds the explosion-proof sheet to the top of the aluminum shell. The jig core has a cantilever or column-shaped structure and is configured to be laterally inserted into the inner cavity of the aluminum shell for support. To ensure welding accuracy and product yield, the width of the jig core is pre-designed according to the tolerance of the aluminum shell stamping mold. When the aluminum shell is fitted into the jig core, the gap is eliminated to prevent the aluminum shell from shaking or deforming during the welding process and to ensure the stability of the laser focal length.

[0026] The front end of the insertion end of the fixture mold core is provided with a guide bevel. During the process of inserting the aluminum shell into the mold core, the bevel plays a guiding role to correct the slight positional deviation of the aluminum shell and prevent the shell opening from rigidly colliding with the edge of the mold core, which would cause jamming or edge curling. The outer surface of the fixture mold core is polished.

[0027] The specific workflow is as follows: After the product handling component 6 inserts the aluminum shell into the fixture core, the lifting component controls the aluminum shell pressure plate to descend, pressing the aluminum shell onto the fixture core from the outside. The descent of the lifting component drives the pressure plate to press tightly, ensuring the height consistency of the welding surface at the top of the aluminum shell. This solves the problem of floating that is easy to occur in traditional fixtures. The lifting component is a corresponding pneumatic component.

[0028] Among them, the preferred laser welding equipment is the galvanometer-type laser welding machine; Aluminum casing correction component 4 includes: The rectifier 401 is connected to the top of the cabinet platform 1 on the side near the aluminum shell loading assembly 3; The receiving plate 403 is connected to the top of the straightening seat 401; The limiting clamp 404 is connected to the top two sides of the receiving plate 403, and abuts against the long side of the aluminum shell through the limiting clamp 404; The positioning clamp 405 is connected to the side of the receiving plate 403 near the limiting clamp 404, and abuts against the short side of the aluminum shell through the positioning clamp 405. A drive cylinder 402 is connected to one side of the aluminum shell alignment component 4. The movable end of the drive cylinder 402 is connected to at least one of the limiting clamps 404. The accommodating distance between the limiting clamps 404 is adjusted by the drive cylinder 402. Specifically: Through the designed aluminum shell alignment component 4, when the aluminum shell feeding component 3 places the aluminum shell between the adjacent limiting clamps 404, the limiting clamps 404 can perform alignment processing on the dropped aluminum shell, which is beneficial to provide guidance stability during the aluminum shell feeding process.

[0029] The aluminum shell feeding assembly 3 includes an aluminum shell feeding module and an aluminum shell feeding clamp that slides along the aluminum shell feeding module. The aluminum shell is transported to the top of the aluminum shell alignment assembly 4 for positioning and alignment through the aluminum shell feeding clamp.
