Description

Technical Field

[0001] This utility model relates to the field of new energy battery production and assembly, and in particular to a device that can drive the battery stack to rotate 180°. Background Technology

[0002] In the process of producing new energy batteries on a production line, when it is necessary to expand the battery capacity, one layer of the battery stack needs to be flipped 180° and then the two layers of batteries are stacked together in a "face-to-face" position. However, due to the large weight of the battery stack (approximately 500 kg per stack), manual operation for flipping is not only difficult and inefficient, but also poses certain safety hazards. Moreover, the traditional flipping method requires temporarily removing the battery stack from the production line, flipping it, and then putting it back on the production line, which seriously affects production efficiency and disrupts the production cycle.

[0003] Therefore, a method or apparatus is needed to solve the above problems. Summary of the Invention

[0004] The present invention addresses the aforementioned shortcomings of the existing technology by proposing a device with a simple structure, ingenious design, and reasonable layout, which can automatically complete a 180° rotation of the battery stack without affecting the production cycle, thereby facilitating subsequent battery stacking operations.

[0006] A longitudinal movement motor 11 is installed at the top of the longitudinal movement frame 4. The input end of the longitudinal movement motor 11 is connected to the input end of a dual-output reduction gearbox 12. The two output ends of the dual-output reduction gearbox 12 are respectively connected to a lifting shaft 13 rotatably supported on the longitudinal movement frame 4. A lifting gear 14 is installed at the end of the lifting shaft 13. The lifting gear 14 meshes with a rack 15 fixedly connected to the frame 1.

[0007] The bottom of the longitudinal moving frame 4 is rotatably supported by a flipping frame 17 via a pivot 16. Two pairs of clamping cylinders 18 are respectively arranged on both sides of the flipping frame 17. The working end of each clamping cylinder 18 is connected to a C-shaped chuck 19, the opening of which matches the side edge of the fuel cell substrate 20.

[0012] This device, capable of driving a fuel cell stack to rotate 180°, boasts a simple structure, ingenious design, and rational layout. Addressing the problems inherent in traditional fuel cell stack rotation methods, it employs a unique structure. It directly interacts with the fuel cell stack conveyor, essentially adding a rotation station to the fuel cell stack production line.

[0021] The specific embodiments of this utility model will be described below with reference to the accompanying drawings. Figures 1 to 8 As shown: A device capable of driving an electric stack to rotate 180° includes a frame 1 as a base, a conveying device disposed below the frame 1, a longitudinal sliding frame 4 slidably connected to the frame 1 via longitudinal slide rails 3, two sets of symmetrically distributed connecting straps 5 connected to the top of the longitudinal sliding frame 4, the connecting straps 5 being connected to a fixed pulley group 6 located at the top of the frame 1, and a counterweight 7 disposed at the other end of the connecting straps 5, the counterweight 7 having a groove, two guide wheels 8 symmetrically distributed on both sides of the groove, and two counterweight guide rails 10 disposed on the front support column 9 of the frame 1, the guide wheels 8 cooperating with the counterweight guide rails 10.

[0022] A longitudinal movement motor 11 is installed at the top of the longitudinal movement frame 4. The input end of the longitudinal movement motor 11 is connected to the input end of a dual-output reduction gearbox 12. The two output ends of the dual-output reduction gearbox 12 are respectively connected to a lifting shaft 13 rotatably supported on the longitudinal movement frame 4. A lifting gear 14 is installed at the end of the lifting shaft 13. The lifting gear 14 meshes with a rack 15 fixedly connected to the frame 1.

[0023] The bottom of the longitudinal moving frame 4 is rotatably supported by a flipping frame 17 via a pivot 16. Two pairs of clamping cylinders 18 are respectively arranged on both sides of the flipping frame 17. The working end of each clamping cylinder 18 is connected to a C-shaped chuck 19, the opening of which matches the side edge of the fuel cell substrate 20. A swing cylinder 21 is also arranged at each of the two opposite corners of the flipping frame 17. A pressure rod 22 is provided on the working end of each swing cylinder 21, and the end of the pressure rod 22 can press against the surface of the fuel cell substrate 20.

[0024] The longitudinal frame 4 is also provided with a tilting motor housing 23 on its side, and a tilting motor is provided inside the tilting motor housing 23. The output end of the tilting motor is connected to the rotating shaft 16 through a gearbox.

[0025] The bottom of the longitudinal frame 4 is also provided with a positioning cylinder 24, and the working end of the positioning cylinder 24 is provided with a positioning pin 25, which matches the limiting pin hole opened on the side of the flip frame 17.

[0026] The lower part of the front support column 9 is provided with a first lower stop block 26 that matches the counterweight block 7, the lower part of the rear support column 27 of the frame 1 is provided with a second lower stop block 28 that matches the bottom end of the longitudinal moving frame 4, and the top of the frame 1 is provided with an upper stop block 29 that matches the top end of the longitudinal moving frame 4.

[0027] The working process of the device that can drive the fuel cell stack to rotate 180° according to the present invention is as follows: In the initial state, the longitudinal moving frame 4 in the device is located at the upper limit position. At this time, the top of the longitudinal moving frame 4 contacts the upper stop block 27 to make way for the fuel cell stack substrate 20 that needs to be rotated.

[0028] Under the action of the conveying device, the fuel cell base plate 20 moves to the bottom of the longitudinal frame 4. The control system sends a signal to the longitudinal motor 11 in this device. The longitudinal motor 11 outputs torque to the dual output reduction gearbox 12. The two lifting shafts 13 connected to the dual output reduction gearbox 12 move simultaneously, driving the two lifting gears 14 to rotate synchronously at the same speed. Since the lifting gears 14 mesh with the rack fixed on the frame 1, the above action will cause the longitudinal frame 4 to move relative to the frame 1 in the longitudinal direction.

[0029] Since the longitudinal frame 4 is connected to the counterweight 7 via the connecting belt 5 and the fixed pulley block 6, the mass of the counterweight is pre-adjusted so that its mass can be roughly balanced with the total mass of the longitudinal frame 4 and the various mechanisms on it. This can reduce the specifications of the longitudinal motor 11 as much as possible, thereby achieving the purpose of saving costs.

[0030] When the bottom of the longitudinal frame 4 contacts the second lower stop block 28 on the rear support column 27, the longitudinal frame 4 can no longer move downward. At this time, the flip frame 17 moves to the same height as the battery stack substrate 20, that is, the battery stack substrate 20 is located inside the flip frame 17.

[0031] Then the control system controls all the clamping cylinders 18 to work. The clamping cylinders 18 drive the C-shaped chucks 19 to move toward the side of the fuel cell stack 20. The pairs of C-shaped chucks 19 clamp the fuel cell stack 20 from both sides. After the clamping cylinders 18 are in place, the control system will also control two swing cylinders 21 distributed at opposite corners to work, so that the end of the clamping rod 22 presses against the surface of the fuel cell stack 20 for further clamping and positioning. After the above actions are completed, the fuel cell stack 20 is fixedly connected to the flipping frame 17.

[0032] Then the longitudinal motor 11 outputs torque in the opposite direction, driving the longitudinal frame 4 and the fuel cell base plate 20 to move upward together. The fuel cell base plate 20 leaves the conveying device. When the top of the longitudinal frame 4 contacts the upper stop block 29, the longitudinal frame 4 moves to the highest position. During the above process, the positioning pin 25 is always inserted into the limiting pin hole opened on the side of the flip frame 17, which can ensure that the flip frame 17 remains relatively fixed with the longitudinal frame 4 during the movement.

[0033] After the longitudinal frame 4 stops moving, the control system sends a signal to the flipping motor. First, the positioning cylinder 24 drives the positioning pin 25 to retract, and the flipping frame 17 regains its degree of freedom. The flipping motor outputs torque to drive the flipping frame 17 to flip 180°. At this time, the original face-up fuel cell substrate 20 flips to face-down. When the sensor next to the positioning cylinder 24 detects the flipping frame 17 again, the control system controls the positioning cylinder 24 to work, and the positioning pin 25 is re-inserted into the limit pin hole to lock the flipping frame 17.

[0034] The longitudinal motor 11 outputs torque in the reverse direction. When the longitudinal frame 4 descends to its bottom end and contacts the second lower stop block 28 again, it stops. At this time, the front (facing downwards) of the fuel cell stack 20 contacts the conveying device. The swing cylinder 21 and the clamping cylinder 18 work in opposite directions to release the lock on the fuel cell stack 20. The fuel cell stack 20 is supported by the conveying device. When the longitudinal frame 4 rises again, the conveying device transports the fuel cell stack 20, which has been rotated 180°, to the next station.
