Description

Technical Field

[0001] The utility model relates to the technical field of lithium battery production, in particular to a feeding mechanism for a lithium battery production line. Background Art

[0002] Lithium battery is a kind of battery that uses lithium metal or lithium alloy as positive / negative electrode material and non-aqueous electrolyte solution. Lithium battery cell refers to a single electrochemical cell containing positive and negative electrodes. It is generally not used directly. It is different from batteries that contain protection circuits and casings and can be used directly. The quality of the cell directly determines the quality of the rechargeable battery. When producing lithium batteries, the cell needs to be flipped over by a loading device.

[0003] The disclosed patent (publication number CN118145293A) discloses a cell loading and flipping device for lithium battery production, comprising a frame, two baffles, a first conveying mechanism and a second conveying mechanism. When the driving motor receives a signal from a touch sensor, it drives the flipping assembly to rotate, thereby flipping the cell onto the second conveying mechanism, so that the cell can be transported by the second conveying mechanism.

[0004] The above-mentioned public patent cannot directly flow away through the conveyor belt after the battery cell is flipped, and it needs to be guided out through a guide plate, and the swinging guide plate is easy to damage the battery. The connecting seat is driven by an independent drive motor, and multiple connecting seats require multiple drive motors, which greatly increases the manufacturing cost and the cost of use is high. In addition, the long-term forward and reverse rotation of the drive motor will aggravate the wear of the motor, resulting in wear of the friction surface, deformation of the magnetic poles, and shortening of the motor life. The use effect is not ideal. Utility Model Content

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-4 The utility model discloses a feeding mechanism for a lithium battery production line, comprising two feeding conveyor lines 1, and a turning mechanism 2 is arranged between the two feeding conveyor lines 1.

[0027] A plurality of conveying troughs 11 are arranged inside the feeding conveying line 1 , and a conveying belt 12 is movably arranged at the bottom of the conveying trough 11 .

[0028] The material turning mechanism 2 includes a fixed frame 21 fixedly arranged between the two feeding conveyor lines 1, a material turning motor 22 is arranged on the top of one side of the fixed frame 21, a driving plate 25 is arranged at the output end of the material turning motor 22, and a material turning frame 26 is arranged at both ends of the driving plate 25, and the opposite ends of the two material turning frames 26 are respectively connected to the two feeding conveyor lines 1, and a receiving groove 27 opposite to the output groove is opened inside the material turning frame 26, and the top and bottom of the receiving groove 27 are opened with a material taking port 28, and one end of the conveyor belt 12 extends to the inside of the material taking port 28 at the bottom of the receiving groove 27.

[0029] Specifically, guide plates 17 are provided on both sides of the inner wall of the conveying trough 11. Figure 1The guide plate 17 inside the left loading conveyor line 1 has the same structure as the guide plate 17 inside the right loading conveyor line 1 and is set asymmetrically. This design allows the guide plate 17 inside the left loading conveyor line 1 to calibrate the position of the battery cells when the battery cells are loaded, so that the battery cells can smoothly enter the storage groove 27, and the guide plate 17 inside the right loading conveyor line 1 can directly guide the battery cells to flow away.

[0030] Specifically, a conveying motor 13 for driving the output belt is provided on one side of the feeding conveyor line 1, and the multiple conveyor belts 12 inside a single feeding conveyor line 1 are all driven by one conveying motor 13, which is more energy-efficient.

[0031] Specifically, the width of the material taking opening 28 is smaller than the width of the storage groove 27 , and the width of the lithium battery cell is larger than the width of the material taking opening 28 , so that the cell will not fall from the material taking opening 28 .

[0032] Specifically, a bracket 23 is provided on the top of one side of the fixed frame 21, and the bracket 23 is U-shaped. A plurality of sensors 24 are provided on both sides of the bracket 23. The U-shaped bracket 23 can simultaneously install two groups of sensors 24, which correspond to two feeding conveyor lines 1 respectively. The turning motor 22 is a servo motor, and the turning motor 22 is set to rotate at an angle of one hundred and eighty degrees each time. The sensor 24 is a groove-type photoelectric switch.

[0033] Specifically, a push plate 29 is movably provided inside the storage groove 27, and a spring 292 is provided on one side of the push plate 29. A sensing piece 291 located on one side of the spring 292 is provided on one side of the push plate 29. The end of the sensing piece 291 away from the push plate 29 penetrates to the outside of the storage groove 27 and is opposite to the sensor 24 on one side thereof. The elastic force of the spring 292 is relatively small. The battery cell is placed inside the conveying groove 11 of the left feeding conveyor line 1. When the conveyor belt 12 conveys the battery cell to the inside of the storage groove 27, the battery cell contacts the push plate 29 to compress the spring 292. At the same time, the sensing piece 291 on one side of the push plate 29 extends to the inside of the groove of the sensor 24 to identify that the battery cell is in place. When all the sensors 24 at one end of the left feeding conveyor line 1 are sensed, the conveyor belt 12 inside the left feeding conveyor line 1 is stopped first, and the turning motor 22 is started to drive the two turning racks 26 to rotate clockwise by one hundred through the driving plate 25. When the left flipping rack 26 drives the battery cell to flip to be opposite to the right loading conveyor line 1, the conveyor belt 12 of the right loading conveyor line 1 does not stop and keeps the conveying state. When the left flipping rack 26 drives the battery cell to flip to be opposite to the right loading conveyor line 1, the conveyor belt inside the right loading conveyor line 1 contacts the battery cell and directly conveys the battery cell inside the storage slot 27 away, thereby ensuring the loading efficiency. At the same time, the original right flipping rack 26 flips to be opposite to the left loading conveyor line 1. Since there is no battery cell inside the flipping rack 26, the push plate 29 remains in the reset state, and the induction sheet 291 does not sense the sensor 24 at one end of the left loading conveyor line 1. At this time, the conveyor belt 12 inside the left loading conveyor line 1 restarts to convey the battery cell into the storage slot 27. When the battery cell is loaded, all the battery cells inside the right flipping rack 26 have flowed away, and the flipping motor 22 is started to repeat the above operation.

[0034] Specifically, one end of the loading conveyor line 1 is provided with a docking groove 14 docking with the tipping rack 26, and the docking groove 14 is used to avoid the tipping rack 26, so that the driving plate 25 can drive the two tipping racks 26 to flip clockwise.

[0035] Specifically, the interior of the loading conveyor line 1 is provided with a conveyor frame 15 that is movably connected to the interior of the conveyor belt 12, and the interior of the conveyor frame 15 is provided with a guide wheel 16 for guiding the conveyor belt 12. Due to the opening of the docking groove 14, the end of the conveyor belt 12 extending to the inside of the feeding port 28 lacks the support of the two side walls of the conveyor groove 11, and the conveyor frame 15 is provided inside the conveyor belt 12 to support it. The two sides of the end of the conveyor frame 15 away from the feeding port 28 are fixedly connected to the inside of the conveyor groove 11.

[0036] To sum up, the feeding mechanism of the lithium battery production line starts the flipping motor 22 to drive the flipping rack 26 to flip the battery cell, and the battery cell flows directly through the feeding conveyor line 1 after flipping. The process is simple and fast, which ensures the feeding efficiency. Starting the flipping motor 22 can drive multiple battery cells to flip at the same time, which is more energy-saving and greatly reduces the manufacturing cost. The flipping motor 22 does not adopt the forward and reverse feeding method, which greatly reduces the loss of the flipping motor 22 and ensures the service life of the flipping motor 22.

[0037] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
