Description

Technical Field

[0001] The utility model relates to the technical field of battery pack processing, in particular to a continuous cell flipping device based on positive and negative pole identification. Background Technique

[0002] In today's energy field, the development of battery technology is crucial. As an important part of the battery, the performance and quality of the battery pack directly affect the overall performance of the battery. During the production process of the battery pack, the flipping operation of the cell is a key link. In the production process of the battery module PACK, the polarities of the battery monomers must be arranged according to the design requirements. In traditional battery pack production, the cell flipping usually adopts manual operation or simple mechanical devices. However, these methods have many problems. Manually flipping the cells not only has a high labor intensity and low efficiency, but also is prone to operation errors, resulting in cell damage and affecting the quality and performance of the battery. Although simple mechanical devices improve the efficiency to a certain extent, they often have defects such as low flipping accuracy and poor adaptability. In modern battery production, in order to meet the production requirements of large scale and high quality, realizing precise, efficient and stable flipping of cells has become a technical problem to be solved urgently. In addition, with the continuous progress of battery technology, the design and structure of cells are becoming increasingly complex, putting forward higher requirements for the flipping operation. Since the positive and negative poles of the battery pack cells are only distinguished by markings during cell processing, when welding the cells, it is necessary to distinguish the positive and negative poles of the cells. The existing devices often use visual recognition to distinguish the positive and negative poles of the cells. However, such recognition methods are affected by the recognition accuracy. Once the recognition is incorrect, the same poles of adjacent cells will be welded together, resulting in defective production of the battery pack, with certain limitations and potential safety hazards.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] Please refer to Figures 1-6 , the present invention provides a technical solution: a cell continuous flipping device based on positive and negative pole identification.

[0029] Embodiment 1: In this embodiment, it is disclosed that there is a frame 1, a guide plate 2 is fixedly arranged at the upper end of the frame 1, and a conveyor belt 3 is arranged between the two guide plates 2. A fixed support seat 4 is fixedly arranged at one end of the frame 1, and a discharge table 5 is fixedly arranged at the other end of the frame 1. A cell body 6 is placed on the upper surface of the conveyor belt 3. A monitoring and flipping mechanism is arranged between the fixed support seat 4 and the discharge table 5, and the control of the positive and negative positions of the cell body 6 is realized by monitoring the positive and negative directions of the cell body 6 in real time;

[0030] The monitoring and flipping mechanism includes: a detection hydraulic rod 7, the detection hydraulic rod 7 is fixedly installed at the upper end of the frame 1, and the lower end of the detection hydraulic rod 7 is fixedly connected with a detection plate 8. A controller 9 is fixedly arranged on the upper surface of the detection plate 8, and a contact column 10 is fixedly arranged on the lower surface of the detection plate 8;

[0031] Two adjacent contact columns 10 are electrically connected to the controller 9 through wires, and the contact columns 10 are located directly above the positive and negative poles of the cell body 6;

[0032] During the operation process, at this time, the cell body 6 to be processed is placed on the conveyor belt 3. At this time, the conveyor belt 3 drives the cell body 6 to move relative to the frame 1. The cell body 6 is guided by the guide plate 2 to move directly opposite to the fixed support seat 4 and finally cross the fixed support seat 4. When the fixed support seat 4 moves in place, at this time, the detection hydraulic rod 7 is started to drive the detection plate 8 to move down until the contact column 10 contacts the positive and negative poles of the cell body 6. At this time, the controller 9 directly above the fixed support seat 4 is recorded as the starting position controller 9, and the first controller 9 adjacent to the starting position controller 9 is recorded as the double-digit controller 9, and the other controller 9 adjacent to the double-digit controller 9 is recorded as the single-digit controller 9, so as to distinguish all the controllers 9 in this way;

[0033] As the contact posts 10 come into contact with the positive and negative electrodes of the battery cell body 6, the starting position controller 9 is powered on. Then, the starting position controller 9 sends an electrical signal to all the adjusting hydraulic rods 12. When the double-digit controller 9 is powered on, all the powered double-digit controllers 9 send electrical signals to the adjusting hydraulic rods 12 at the corresponding positions directly below. The adjusting hydraulic rods 12 act to adjust the direction of the battery cell body 6. When the single-digit controller 9 is not powered on, the adjusting hydraulic rods 12 at the corresponding positions directly below all the non-powered single-digit controllers 9 act to adjust the direction of the battery cell body 6;

[0034] As the contact posts 10 come into contact with the positive and negative electrodes of the battery cell body 6, the starting position controller 9 is not powered on. Then, the starting position controller 9 sends an electrical signal to all the adjusting hydraulic rods 12. When the double-digit controller 9 is not powered on, the adjusting hydraulic rods 12 at the corresponding positions directly below all the non-powered double-digit controllers 9 act to adjust the direction of the battery cell body 6. When the single-digit controller 9 is powered on, all the powered single-digit controllers 9 send electrical signals to the adjusting hydraulic rods 12 at the corresponding positions directly below. The adjusting hydraulic rods 12 act to adjust the direction of the battery cell body 6;

[0035] Thus, the orientation of the positive and negative electrodes of the battery cell body 6 directly below the double-digit controller 9 is always opposite to the orientation of the positive and negative electrodes of the battery cell body 6 directly below the starting position controller 9, and the orientation of the positive and negative electrodes of the battery cell body 6 directly below the double-digit controller 9 is always opposite to the orientation of the positive and negative electrodes of the battery cell body 6 directly below the single-digit controller 9, ensuring the correct orientation of the positive and negative electrodes of the battery cell body 6 during subsequent welding;

[0036] The battery cell body 6 with the direction adjustment completed is pushed by the subsequent moving battery cell body 6 and moves to the discharge table 5 for discharging.

[0037] Embodiment 2: On the basis of Embodiment 1, this embodiment discloses that the monitoring and flipping mechanism further includes: a support plate 11, the support plate 11 is fixedly arranged at the lower end of the frame 1, a rotating adjusting hydraulic rod 12 is installed on the outer surface of the lower end of the frame 1, and an adjusting gear 13 is fixedly arranged on the side surface of the lower end of the adjusting hydraulic rod 12. A motor 14 is fixedly installed on the outer surface of the lower end of the frame 1, and a transmission gear 15 is fixedly connected to the lower end of the output shaft of the motor 14. The upper end of the adjusting hydraulic rod 12 is fixedly connected with a lifting and supporting seat 16, and sliding side clamping plates 17 are installed at both ends of the lifting and supporting seat 16. Piston cylinders 18 are fixedly arranged on the lower surfaces of both ends of the lifting and supporting seat 16, and contact rods 19 are slidably connected to the lower ends of the piston cylinders 18;

[0038] The upper end of the adjusting hydraulic rod 12 penetrates through the upper surface of the support plate 11, and the adjusting hydraulic rod 12 is rotatably connected to the support plate 11;

[0039] The adjusting gear 13 and the transmission gear 15 are in meshing connection, and the adjusting gear 13 and the adjusting hydraulic rod 12 are concentrically arranged;

[0040] One end of the side clamping plate 17 inside the lifting support seat 16 is designed in a C shape, and one end of the side clamping plate 17 inside the lifting support seat 16 penetrates through the upper end of the piston cylinder 18. The piston cylinder 18 is in sliding friction connection with the contact rod 19, and a spring is connected between the piston cylinder 18 and the contact rod 19. And a ball is embedded in the lower end surface of the contact rod 19;

[0041] When the adjusting hydraulic rod 12 needs to act to adjust the positive and negative directions of the battery cell body 6, at this time, the adjusting hydraulic rod 12 starts to drive the lifting support seat 16 to slide downward. At this time, the battery cell body 6 moves downward as the lifting support seat 16 slides downward until the ball at the lower end of the contact rod 19 contacts the upper surface of the support plate 11 and slides relative to the piston cylinder 18. The pressure inside the piston cylinder 18 increases and pushes one end of the side clamping plate 17 inside the lifting support seat 16, so that the two lifting support seats 16 move towards the battery cell body 6 to clamp the battery cell body 6. Then, the motor 14 drives the adjusting hydraulic rod 12 to rotate through the meshing of the transmission gear 15 and the adjusting gear 13, so that the adjusting hydraulic rod 12 is driven to rotate 180°, achieving the purpose of swapping the positive and negative directions of the battery cell body 6. Then, the adjusting hydraulic rod 12 drives the lifting support seat 16 to move upward to reset the battery cell body 6.

[0042] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
