Detailed ways

The present invention will be further described below in conjunction with the accompanying drawings.

A square lithium battery welding device comprises a lithium battery welding device, a detection device, a feeding device 12, a unloading device 13 and a transfer mechanism 14. The feeding device 12 is connected to the lithium battery welding device, and the battery to be welded is provided to the feeding clamping claw 4-3 of the lithium battery welding device through the feeding device 12. The lithium battery detection device is connected to the detection device through the transfer mechanism 14. After the lithium battery detection device completes the battery welding, the welding-completed battery is transported to the bottom of the transfer mechanism 14 through the feeding clamping claw 4-3. The transfer mechanism 14 moves the welding-completed battery into the detection device. The detection device is connected to the unloading device 13, and the unloading device 13 unloads the detected battery.

The lithium battery welding device includes a welding feeding mechanism 4, a welding seat 3 and a welding mechanism 5 installed on the welding seat 3, a welding leveling mechanism 1, and a welding cover feeding mechanism 2. The welding leveling mechanism 1 is slidably installed on the welding seat 3 so that the welding leveling mechanism 1 moves to the bottom of the welding mechanism 5 and the welding leveling mechanism 1. Battery placement grooves 1-5 are provided in the welding leveling mechanism 1. The welding feeding mechanism 4 is adapted to the battery placement grooves 1-5 to transport the battery from bottom to top into the welding leveling mechanism 1. The welding device can automatically complete the processes of loading, leveling, covering with protective covers and welding the batteries to be welded, thereby improving the welding efficiency of automatic battery welding.

The welding leveling mechanism 1 includes a top leveling component 1-1, a leveling base 1-2, and a transverse leveling component 1-3 and a longitudinal fixing component 1-4 fixed on the leveling base 1-2. A battery placement slot 1-5 is provided in the leveling base 1-2. The square lithium battery shell is moved into the leveling mechanism through the battery placement slot 1-5. The top leveling component 1-1 is arranged above the battery placement slot 1-5. The transverse leveling component 1-3 and the longitudinal fixing component 1-4 are respectively arranged toward the battery placement slot 1-5. By placing the square battery shell in the leveling mechanism from bottom to top, it is convenient to level the three directions (transverse, longitudinal, and vertical) of the battery shell to be welded through the top leveling component 1-1, the transverse leveling component 1-3, and the longitudinal fixing component 1-4, thereby ensuring the position accuracy of the battery shell welding part and ensuring the welding yield.

The longitudinal fixing assembly 1-4 includes a longitudinal fixing seat 1-6 and a longitudinal adjustment member 1-7 arranged toward the longitudinal fixing seat 1-6. A longitudinal top block 1-8 is installed on the longitudinal adjustment member 1-7. The longitudinal top block 1-8 is driven by the longitudinal adjustment member 1-7 to move toward the longitudinal fixing seat 1-6. The battery shell is clamped by the longitudinal top block 1-8 and the longitudinal fixing seat 1-6 to achieve longitudinal leveling of the battery shell.

The longitudinal adjustment member 1-7 includes a longitudinal movable plate 1-12 and a longitudinal leveling plate 1-13 and a longitudinal leveling cylinder 1-14 installed on the longitudinal movable plate 1-12. The longitudinal movable plate 1-12 is slidably installed on the leveling base 1-2 through a slide rail. When the longitudinal fixed component 1-4 clamps battery shells of different sizes, it is necessary to adjust the clamping position of the longitudinal top block 1-8. By adjusting the longitudinal movable plate 1-12, it is convenient to adjust the lateral position of the longitudinal leveling plate 1-13 and the longitudinal leveling cylinder 1-14, thereby realizing the position adjustment of the longitudinal top block 1-8 and ensuring the clamping stability of the longitudinal fixed component 1-4. The longitudinal top block 1-8 is installed on the longitudinal leveling plate 1-13, and the longitudinal leveling cylinder 1-14 is connected to the longitudinal leveling plate 1-13. The longitudinal leveling cylinder 1-4 drives the longitudinal leveling plate 1-13 to move, thereby driving the longitudinal top block 1-8 to move.

In order to facilitate the battery shell to move from bottom to top into the longitudinal fixing assembly 1-4, a through groove is also provided in the longitudinal movable plate 1-12, and the through groove is connected to the battery placement through groove 1-5, so as to facilitate the battery shell to be moved between the longitudinal top block 1-8 and the longitudinal fixing seat 1-6.

A transverse fine-tuning member 1-15 is installed on the leveling base 1-2. The transverse fine-tuning member 1-15 is abutted against both sides of the longitudinal movable plate 1-12 to adjust the transverse position of the longitudinal movable plate 1-12. The transverse fine-tuning member 1-15 includes an adjusting base 1-16, an adjusting rod 1-17 installed on the adjusting base 1-16, and an adjusting nut 1-18 installed on the adjusting rod 1-17. The adjusting nut 1-18 abuts against the longitudinal movable plate 1-12. The adjusting rod 1-17 penetrates the longitudinal movable plate 1-12. The adjusting nuts 1-18 are arranged on both sides of the longitudinal movable plate 1-12. By adjusting the two adjusting nuts 1-18, the transverse position adjustment of the longitudinal movable plate 1-12 is achieved.

A longitudinal fixed gap is formed between the longitudinal top block 1-8 and the longitudinal fixing seat 1-6, and the battery is fixed in the longitudinal fixed gap. The transverse leveling component 1-3 is adapted to the longitudinal fixed gap, that is, the transverse leveling component 1-3 at least partially extends into the longitudinal fixed gap, thereby facilitating the pushing and leveling of the battery shell clamped between the longitudinal top block 1-8 and the longitudinal fixing seat 1-6.

The transverse leveling assembly 1-3 also includes a transverse fixing seat 1-10 and a transverse adjusting member 1-11. The adjusting member is arranged toward the transverse fixing seat 1-10. The transverse top block 1-9 is connected to the transverse adjusting member 1-11. The transverse adjusting member 1-11 is a cylinder. The transverse top block 1-9 is pushed toward the top block transverse fixing seat 1-10 by the cylinder, so that the battery shell is pressed against the top block transverse fixing seat 1-10, and the battery shell is leveled laterally by the top block transverse fixing seat 1-10.

The transverse top block 1-9 is L-shaped, which makes it easy for the transverse top block 1-9 to extend into the longitudinal fixing gap, thereby facilitating the transverse pushing of the battery shell through the transverse top block 1-9 after the longitudinal fixing assembly 1-4 clamps the battery shell.

The top leveling assembly 1-1 includes a top leveling cylinder 1-21 and a top leveling block 1-22 connected to the top leveling cylinder 1-21. The top leveling block 1-22 is arranged toward the battery placement slot 1-5, and the top of the battery shell is leveled by the top leveling block 1-22.

The working principle of the leveling mechanism is as follows: (1) first move the top leveling block 1-22 to the height at which the battery shell is to be welded; (2) the battery shell is placed in the leveling mechanism from bottom to top, so that the top of the battery shell abuts against the lower end surface of the top leveling block 1-22 to achieve vertical leveling; (3) the longitudinal fixing component 1-4 clamps the battery shell to achieve longitudinal leveling; (4) the transverse leveling component 1-3 clamps the battery shell to achieve transverse leveling.

The transverse leveling component 1-3 and the longitudinal fixing component 1-4 are both equipped with damping parts, which include a damping baffle 1-19 and a damper 1-20. The damper 1-20 is connected to the transverse top block 1-9. The damping baffle 1-19 is arranged on the leveling base 1-2. The damper 1-20 is a gas spring. The damper 1-20 provides a certain buffering effect on the force of the longitudinal top block 1-8 and the transverse top block 1-9 toward the battery shell, thereby preventing the battery shell from deforming during the leveling process.

A welding slide rail 1-23 is provided on the lower end surface of the leveling base 1-2, so that the leveling base 1-2 can be moved through the welding slide rail 1-23 to move the battery shell fixed on the leveling mechanism.

The welding cover feeding mechanism 2 includes a cover feeding assembly 2-1, a cover feeding manipulator 2-2 and two upper cover manipulators 2-3. The two cover feeding manipulators 2-2 and the upper cover manipulators 2-3 are respectively installed on both sides of the manipulator beam 2-4, reducing the installation space required for the cover feeding manipulators 2-2 and the upper cover manipulators 2-3. The cover feeding assembly 2-1 is connected to the two upper cover manipulators 2-3 through the cover feeding manipulators 2-2, and the two batteries are respectively covered with protective covers through the two upper cover manipulators 2-3. When one of the batteries is being welded, the other upper cover manipulator 2-3 covers the other battery with a protective cover, thereby reducing the waiting time for the protective cover to be covered during the battery welding process and improving the battery welding efficiency.

The cover feeding mechanism also includes two transfer platforms 2-5, which are installed on the welding seat 3 through slide rails. The transfer platform 2-5 is connected to the leveling base 1-2, and the transfer platform 2-5 is driven to move by the leveling base 1-2, so that the transfer platform 2-5 moves vertically along the manipulator beam 2-4. The two upper cover manipulators 2-3 are respectively adapted to the two transfer platforms 2-5, that is, the transfer platform 2-5 is arranged below the upper cover manipulator 2-3, and the cover feeding manipulator 2-2 places the protective cover on the transfer platform 2-5, and moves the protective cover to the bottom of the upper cover manipulator 2-3 through the movement of the transfer platform 2-5, so as to facilitate the upper cover manipulator 2-3 to clamp the protective cover.

A cover delivery translation assembly 2-6 is provided on the manipulator cross beam 2-4, and the cover delivery translation assembly 2-6 is connected to the cover delivery manipulator 2-2. The cover delivery manipulator 2-2 is driven to move by the cover delivery translation assembly 2-6, and the cover delivery manipulator 2-2 is moved above the corresponding transfer platform 2-5.

The cover feeding translation assembly 2-6 includes a translation motor 2-25, a translation frame 2-26 and a translation block 2-27. The translation block 2-27 is slidably installed on the translation frame 2-26. The translation motor 2-25 is connected to the translation block 2-27 through a synchronous belt to drive the translation block 2-27 to move. The cover feeding robot 2-2 is installed on the translation block 2-27.

The cover feeding robot 2-2 and the cover upper robot 2-3 both include a protective cover clamping member, which is used to clamp the protective cover.

The protective cover clamping member includes a clamping cylinder 2-7 and two protective cover clamping claws 2-8 connected to the clamping cylinder 2-7. The two protective cover clamping claws 2-8 are provided with clamping claw plates 2-9 arranged opposite to each other. The side walls of the protective cover are clamped by the clamping claw plates 2-9 to prevent the upper end or lower end of the clamping claw plates 2-9 from exceeding the upper end or lower end of the protective cover, thereby facilitating the protective cover to be placed on the battery.

The protective cover clamp 2-8 includes a connecting plate 2-10, which is connected to the clamping cylinder 2-7 through a connecting block 2-11. The clamp plate 2-9 and the connecting block 2-11 are arranged on the same side of the connecting plate 2-10, so that the protective cover clamp 2-8 has a 匚-shaped structure, which is convenient for clamping the battery protective cover.

The protective cover clamping member also includes a clamping member mounting seat 2-12, a clamping guide plate 2-13, a clamping lifting cylinder 2-14 and a clamping mounting block 2-15. The clamping guide plate 2-13 is connected to the clamping member mounting seat 2-12 through a guide column 2-16, the clamping lifting cylinder 2-14 is installed on the clamping guide plate 2-13, the clamping mounting block 2-15 is connected to the clamping lifting cylinder 2-14, and the clamping cylinder 2-7 is installed on the clamping mounting block 2-15.

When clamping the protective cover, the protective cover clamping claw 2-8 is first moved downward by the clamping lifting cylinder 2-14, and then the protective cover clamping claw 2-8 is driven by the clamping cylinder 2-7 to clamp the protective cover.

In order to ensure the height position accuracy of the upper cover manipulator 2-3, a lifting limit assembly is installed on the upper cover manipulator 2-3 for limiting the upward movement of the protective cover clamping part. The lifting limit assembly includes a lifting limit baffle 2-17 and a lifting limit sensor 2-18 adapted to the lifting limit baffle 2-17 to prevent the protective cover clamped on the upper cover manipulator 2-3 from having a height error, thereby ensuring that the protective cover can be stably covered on the top of the battery.

The cover feeding robot 2-2 also includes a robot lifting assembly, which is used to lift the protective cover clamping part. The robot lifting assembly includes a lifting motor 2-19, a lifting guide rail 2-20 and a lifting slider 2-21. The protective cover clamping part is slidably installed on the lifting guide rail 2-20 through the lifting slider 2-21, and the lifting motor 2-19 is connected to the lifting slider 2-21 through a screw rod.

The welding feeding mechanism 4 includes a feeding slide 4-1, a feeding lifting assembly 4-2 and a feeding clamping claw 4-3. The feeding lifting assembly 4-2 is slidably installed on the feeding slide 4-1 through a slider. Preferably, a screw and a motor are provided on the feeding slide 4-1. The motor drives the screw to rotate, thereby driving the slider to move, thereby driving the feeding lifting assembly 4-2 to translate. The feeding clamping claw 4-3 is installed on the feeding lifting assembly 4-2. The feeding clamping claw 4-3 is adapted to the battery placement slot 1-5 to transport the battery from bottom to top into the welding leveling mechanism 1.

The structure of the loading lifting assembly 4-2 is consistent with the structure of the manipulator lifting assembly in the welding cover feeding mechanism 2, and is used to drive the loading clamping claw 4-3 to move up and down.

The welding mechanism 5 includes a welding head lifting assembly 5-1, a welding head 5-2 installed on the welding head lifting assembly 5-1, and a welding dust suction piece 5-3. The welding dust suction piece 5-3 is arranged on one side of the welding head 5-1. Similarly, the structure of the welding lifting assembly 5-1 is consistent with the structure of the manipulator lifting assembly in the welding cover feeding mechanism 2, and is used to drive the welding head 5-2 and the welding dust suction piece 5-3 to move up and down.

The detection device includes a detection conveying mechanism 7 and a visual detection mechanism 8, a burr removal mechanism 9, and a short-circuit detection mechanism 10 adapted to the detection conveying mechanism 7. The visual detection mechanism 8, the burr removal mechanism 9, and the short-circuit detection mechanism 10 are arranged in sequence, so that the detection conveying mechanism 7 can move the welded battery to the visual detection mechanism 8, the burr removal mechanism 9, and the short-circuit detection mechanism 10 in sequence, and the welded battery is visually inspected by the visual detection mechanism 8. The burr removal mechanism 9 is used to remove the burrs on the surface of the battery after welding, and the short-circuit detection mechanism 10 is used to perform short-circuit detection on the battery. By arranging the burr removal mechanism 9 at the front end of the short-circuit detection mechanism 10, the burrs on the surface of the battery after welding are prevented from affecting the short-circuit detection mechanism 10, thereby improving the detection stability of the welding detection device.

The deburring mechanism 9 includes a deburring clamp 9-1 and a burr pressing component 9-2 and a burr removal component 9-3 arranged on both sides of the deburring clamp 9-1, which are convenient for deburring both sides of the battery after welding and improve the efficiency of deburring. The burr removal component 9-3 is arranged at the front end of the burr pressing component 9-2, and the burr pressing component 9-2 is used to press the part to be deburred, thereby further ensuring the flatness of the battery surface.

The burr removal component 9-3 includes a brush 9-4, a brush motor 9-5 for driving the brush 9-4 to rotate, and a deburring cylinder 9-6. The brush motor 9-5 is connected to the brush 9-4, and the deburring cylinder 9-6 is connected to the brush 9-4 to drive the brush 9-4 to move. The deburring cylinder 9-6 moves the brush 9-4 to the battery surface, and then the brush 9-4 is rotated by the brush motor 9-5, thereby removing the burrs on the battery surface by the brush 9-4.

The burr pressing assembly 9-2 is connected to the burr removal cylinder 9-6, and the burr pressing assembly 9-2 and the brush 9-4 are driven to move by the burr removal cylinder 9-6 at the same time, thereby simplifying the structure of the burr removal mechanism 9.

In order to prevent the removed burrs from splashing, a dust collection sleeve 9-9 is provided on the outer side of the brush 9-4, and the dust collection sleeve 9-9 is connected to an external vacuum cleaner to collect the fallen burrs.

The short-circuit detection mechanism 10 includes a short-circuit clamp 10-1, a short-circuit contact 10-2 and a short-circuit drive 10-3. The short-circuit contact 10-2 is arranged toward the short-circuit clamp 10-1, and the short-circuit drive 10-3 is connected to the short-circuit contact 10-2. The short-circuit drive 10-3 drives the short-circuit contact 10-2 to rise and fall, so that the short-circuit contact 10-2 comes into contact with the motor of the battery, thereby realizing short-circuit detection.

The short-circuit contact 10-2 is connected to the short-circuit driving member 10-3 through a short-circuit connecting frame. The short-circuit connecting frame includes an adjusting plate 10-4 and a contact mounting plate 10-5. The adjusting plate 10-4 is provided with a waist-shaped groove 10-6.

The detection fixture 7-4 is installed on the detection lifting plate 7-2. In this embodiment, the lifting seat 7-1 is slidably installed through a slide rail 7-5, so as to facilitate the detection and conveying mechanism 7 to move to the bottom of the visual inspection mechanism 8, the burr removal mechanism 9 and the short-circuit detection mechanism 10.

Four detection and conveying mechanisms 7 and conveying steppers 11 are provided in the detection device. A detection and conveying mechanism 7 is correspondingly adapted under each of the visual detection mechanism 8, the burr removal mechanism 9 and the short-circuit detection mechanism 10. Adjacent detection and conveying mechanisms 7 are connected by connecting plates 7-6. The conveying steppers 11 are connected to the connecting plates 7-6. The connecting plates 7-6 are driven to translate by the conveying steppers 11, thereby facilitating driving the detection and conveying mechanisms 7.

In the initial state, the detection and conveying mechanism 7 at the end is used to receive the battery to be detected. The detection and conveying mechanism 7 works, and the four detection and conveying mechanisms 7 respectively perform material collection, visual inspection, burr removal, and short-circuit inspection. After the inspection is completed, the detection and conveying mechanism 7 clamps and lowers the battery, and then the conveying stepper 11 works to drive the detection and conveying mechanism 7 to move forward one station as a whole. At this time, the frontmost detection and conveying mechanism 7 is located at the unloading station, and the detection and conveying mechanism 7 works to lift the battery. The four detection and conveying mechanisms 7 respectively perform visual inspection, burr removal, short-circuit inspection, and unloading. When the battery is clamped at the corresponding detection or unloading station, the detection and conveying mechanism 7 descends, and the conveying stepper 11 resets all the detection and conveying mechanisms 7 to the initial state (the detection and conveying mechanism 7 at the end is at the station for receiving the battery to be detected); thereby realizing different inspections on multiple batteries at the same time and improving the inspection efficiency of the device.

In this embodiment, the conveying stepper 11 is used to translate the detection conveying mechanism 7. It can adopt a structure in which a motor, a screw slider mechanism are coordinated, or a structure in which a motor, a belt, and a pulley are coordinated. This application does not involve improving the detection conveying mechanism 7.

The structures of the loading device 12 and the unloading device 13 are similar, both of which include a mobile manipulator and a conveyor belt, wherein the structure of the mobile manipulator is consistent with the structure of the transfer mechanism 14, and the mobile manipulator is used to move the battery on the conveyor belt to the lithium battery welding device for loading, or to move the battery in the detection device to the conveyor belt for unloading; the transfer mechanism 14 is used to move the battery of the loading clamping claw 4-3 to the detection fixture 7-4.
