The NG buffer module 14 collects unqualified cells 31 and uniformly transports them to a designated location after a certain number of cells have been collected.

[0047] A method for electromagnetic hot pressing of a battery core, comprising the following steps:

[0048] S1, obtaining the status of the battery cell 31; using the code scanning module 12 to monitor whether the battery cell 31 has moved to the set position, and feeding back to the electrical control module, after the plurality of battery cells 31 have moved to the set position, using the electrical control module to control the automatic loading and unloading module 11 to start;

[0049] S2, clamping and transferring the battery cells 31 in batches; using the automatic loading and unloading module 11 to clamp a plurality of the battery cells 31 at the same time, adjusting the posture of the automatic loading and unloading module 11 to change the plurality of horizontally arranged battery cells 31 into a vertically arranged state, and using the electrical control module to control the automatic loading and unloading module 11 to transfer the plurality of vertically arranged battery cells 31 to the battery cell electromagnetic hot pressure test module 13;

[0050] S3, electromagnetic hot pressing: using the battery core electromagnetic hot pressing test module 13 to perform electromagnetic hot pressing on the plurality of battery cores 31;

[0051] S4, obtaining the qualified status of the battery cell 31; detecting whether the battery cell 31 is qualified after electric heating and pressing, and feeding back to the electrical control system;

[0052] S5, classified transfer; through the electrical control system, the unqualified battery cells 31 are first taken out by the NG buffer module 14, and then the qualified battery cells 31 are transferred to the next process by the automatic loading and unloading module 11.

[0053] Working principle of the present invention:

[0054] In the initial state, the battery cells 31 are continuously conveyed from the conveyor belt 2 18 to the position of the battery cell electromagnetic hot pressure test module 13 .

[0055] The code scanning module 12 monitors the battery cells 31 to obtain their position information. Taking the embodiment in the attached figure as an example, after the code scanning module 12 recognizes that four battery cells 31 have passed, it feeds back instructions to the electrical control system, the conveyor belt 2 18 stops conveying, and the clamping unit starts working.

[0056] When the clamping unit is working, the clamping jaws 30 are initially in an open state, and the cylinders are used to control the movable plate 19 to move relative to the frame outer cover module and the sliding plate 36 to slide relative to the fixed cover 20, so that the four clamping units are close to the four battery cells 31; then the clamping jaws 30 are started to control the piston rods on both sides to move closer, so that the two clamping cylinders 28 clamp the battery cell 31, and the hook 37 lifts the battery cell 31.

[0057] During the above process, after the two calibration rods 46 hit the battery cell 31, the mounting rod 59 and the rotating sleeve 45 are caused to rotate, and the torsion spring connecting the rotating sleeve 45 and the clamping cylinder 28 is twisted and accumulates elastic potential energy. The telescopic rod 44 slides when rotating with the rotating sleeve 45, and the telescopic rod 44 drives the rack 43 to move, and the rack 43 and the fixed rail 38 slide. Since the two racks 43 are meshed with the control gear at the same time, the distance and speed of the two racks 43 are always consistent, resulting in the same rotation of the two rotating sleeves 45, ensuring that the battery cell 31 is located in the middle position of the two clamping cylinders 28.

[0058] When all four battery cells 31 are clamped, the control motor 52 and the drive motor 49 are started, and the control motor 52 controls the rotation of the active pulley 54, and the active pulley 54 drives the driven pulley 51 to rotate through the synchronous belt three 55, and the control shaft 56 and the supporting plate 35 rotate together with the driven pulley 51. At the same time, the drive motor 49 controls the rotation of the transmission pulley 48, and the transmission pulley 48 drives the driving pulley 60 to rotate through the synchronous belt two 50, and the control sleeve 62 and the rotating pulley rotate together with the driving pulley 60, and the rotating pulley drives multiple control pulleys 42 to rotate synchronously through the synchronous belt one 47. The rotation directions of the control pulley 42 and the supporting plate 35 are opposite. When the supporting plate 35 rotates from a horizontal state to a vertical state, the control pulley 42 rotates in the opposite direction, so that the multiple rotating shafts 41, the rotating disk 34 and the clamping units rotate synchronously in the opposite direction to keep the multiple clamping units always horizontal.

[0059] After the postures of multiple battery cells 31 are adjusted, they are sent to the battery cell electromagnetic hot pressing test module 13 at the same time, and the electrical control module controls the drive cylinder 24 to start. At the same time, the high-frequency and high-voltage current in the hot pressing plate 23 changes rapidly and flows through the coil to generate a high-speed changing alternating magnetic field to heat the battery cells 31. The piston rod of the drive cylinder 24 drives the uppermost hot pressing plate 23 to press down, and the uppermost hot pressing plate 23 and the guide rod 21 slide. Under the action of the rope assembly 22, multiple hot pressing plates 23 will move synchronously, and then four will be squeezed at the same time; after the electromagnetic hot pressing is completed, the drive cylinder 24 is reset, and the battery cells 31 are detected by using sensors between the multiple hot pressing plates 23, and unqualified battery cells 31 are fed back to the electromagnetic control system.

[0060] After receiving the instruction, the NG cache module 14 cooperates with the lifting cylinder 58 to take out the unqualified battery cell 31; the lifting cylinder 58 starts to control the lifting of the moving plate 57, so that the horizontal position of one of the unqualified battery cells 31 is consistent with the NG cache module 14, and the linear motor controls the load-bearing beam 27 and the sliding seat 29 to move the clamping component of the NG cache module 14 to a suitable position, and the unqualified battery cell 31 is taken out and placed on the conveyor belt 17, which is collected and transported to the designated position by the conveyor belt 17; after multiple unqualified battery cells 31 are taken out in turn through the above operations, the battery cell electromagnetic hot pressure test module 13 is reset, and the remaining qualified battery cells 31 are taken out by the automatic loading and unloading module 11 and put back on the conveyor belt 2 18 to continue to be transported to the next process.

[0061] When the above-mentioned clamping unit places the battery cell 31, under the action of the torsion spring, the two calibration rods 46 always keep in contact with the two side edges of the battery cell 31. The principle is the same as the above-mentioned clamping. Under the action of the control gear, the sliding distance of the two racks 43 is the same, so the battery cell 31 will always remain in the middle of the two clamping cylinders 28; even if the hook 37 is worn, the degree of friction between the hooks 37 on both sides and the bottom surface of the battery cell 31 is different. The hook 37 on one side is not easy to separate from the battery cell 31, and it will not cause the battery cell 31 to be dragged to one side by the hook 37 when placing it, ensuring that the battery cell 31 is located in the effective heating area on the hot pressing plate 23, and ensuring the yield of electromagnetic hot pressing.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner.
