[0002] In the battery manufacturing process, bare cells need to be preheated before hot pressing. The traditional heating method is to place the cells on a multi-layer heating rack first, then push them into the heating equipment as a whole, and take them out after heating for a period of time. This solution has low loading and unloading efficiency and low automation, which affects production capacity. There is also a heating device that includes multiple heating trays in an upper and lower array. All heating trays can be pulled out and retracted.

[0029] The following is combined with Figure 1-10 This application is described in further detail.

[0030] Reference Figure 1 and Figure 2 The embodiment of the present application discloses a loading device of a battery cell heating device 100, including a material picking robot 1, a battery cell transfer mechanism 2 and a plate placing robot 3, wherein the material picking robot 1 is used to grab a plurality of battery cells 200 to be heated and transfer the battery cells 200 to the battery cell transfer mechanism 2, the battery cell transfer mechanism 2 is used to move the battery cells 200 horizontally to directly below the plate placing robot 3, and the plate placing robot 3 is used to grab the battery cells 200 in the battery cell transfer mechanism 2 and lift the battery cells 200 vertically to place them on the heating tray 101 of the battery cell heating device 100.

[0031] The battery cell heating device 100 is provided with a fork mechanism, which can selectively push out the heating tray 101. By controlling the pushing distance, the battery cells 200 can be placed at different positions of the heating tray 101 by relying on the lifting and lowering action of the plate placing robot 3 while the horizontal position of the plate placing robot 3 remains unchanged.

[0032] Reference Figure 3 and Figure 4The material picking manipulator 1 includes a YZ two-axis moving platform 11, a first mounting frame 12, a plurality of first mechanical grippers 13 and a gripper distance adjustment structure 14. The YZ two-axis moving platform 11 is used to drive the first mounting frame 12 to move. The plurality of first mechanical grippers 13 are all slidably arranged on the first mounting frame 12. The gripper distance adjustment structure 14 is used to drive the plurality of first mechanical grippers 13 to move so as to adjust the spacing between the first mechanical grippers 13. The number of the material picking manipulators 1 described in this embodiment is two groups, which are arranged horizontally in parallel to double the feeding efficiency and meet the needs of large-scale production; each group of material picking manipulators 1 includes four first mechanical grippers 13, which can grab four battery cells 200 at a time. The two groups of material picking manipulators 1 are generally arranged front and back in a staggered manner to grab battery cells 200 conveyed by different material belts, and can also grab different types of battery cells 200, such as the common AB battery cells. Generally, the battery cells 200 conveyed by the material belt have large spacings, and need to be narrowed before being placed in the heating tray 101 . This can increase the capacity of the heating tray 101 and improve the yield.

[0033] Reference Figure 5 and Figure 6 The first mechanical clamp 13 includes a rotating cylinder 131, a first two-way opening and closing cylinder 132, a first battery cell pressing cylinder 133, a second battery cell pressing cylinder 134, a first L-shaped clamp 135 and a second L-shaped clamp 136. The first two-way opening and closing cylinder 132 is used to drive the first L-shaped clamp 135 and the second L-shaped clamp 136 to clamp and move away from each other to grasp or release the battery cell 200. The rotating cylinder 131 is used to drive the first two-way opening and closing cylinder 132 to rotate to adjust the orientation of the battery cell 200. The first battery cell pressing cylinder 133 is used to press the battery cell 200 onto the first L-shaped clamp 135. The second battery cell pressing cylinder 134 is used to press the battery cell 200 onto the second L-shaped clamp 136. In this embodiment, the direction of the battery cell 200 conveyed by the material belt is not matched, and it needs to be rotated 90 degrees or 180 degrees to adjust the direction before being placed in the heating tray 101, so a rotating cylinder 131 is provided to drive the first two-way opening and closing cylinder 132, the first L-shaped clamping jaw 135 and the second L-shaped clamping jaw 136 to rotate as a whole, thereby driving the battery cell 200 to adjust the direction. The first battery cell pressing cylinder 133 and the second battery cell pressing cylinder 134 can stably press the battery cell 200 on the first L-shaped clamping jaw 135 and the second L-shaped clamping jaw 136 to prevent displacement during the transfer process, affect the transfer accuracy, and prevent the battery cell 200 from falling.

[0034] Reference Figure 1, anti-collision detection frames 15 are provided on both cylinder shafts of the first two-way opening and closing cylinder 132, and the first L-shaped clamping jaw 135 and the second L-shaped clamping jaw 136 are elastically slidably arranged on the anti-collision detection frames 15 on both sides, respectively, and a displacement detector 16 is provided on the anti-collision detection frame 15 for detecting the movement of the first L-shaped clamping jaw 135 and the second L-shaped clamping jaw 136 on the anti-collision detection frame 15. By arranging elastic elements such as springs, the first L-shaped clamping jaw 135 and the second L-shaped clamping jaw 136 have a certain elastic floating ability in the vertical direction. When the first L-shaped clamping jaw 135 or the second L-shaped clamping jaw 136 is blocked in the vertical direction, it will be displaced upward relative to the anti-collision detection frame 15. At this time, when the displacement detector 16 detects the displacement, it is considered that the first L-shaped clamping jaw 135 or the second L-shaped clamping jaw 136 has collided with an external object, and an alarm signal can be generated, and the machine is stopped for inspection, thereby improving the safety of the feeding device.

[0035] Reference Figure 4 The clamping jaw distance adjustment structure 14 includes a distance adjustment cylinder 141 and a distance adjustment assembly 142. The distance adjustment assembly 142 is used to connect adjacent first mechanical clamping jaws 13. The distance adjustment cylinder 141 is set on the first mounting frame 12 and is used to drive the outermost first mechanical clamping jaws 13 to move. The outermost first mechanical clamping jaws 13 drag the adjacent first mechanical clamping jaws 13 to move in sequence through the distance adjustment assembly 142 to achieve the distance change between the first mechanical clamping jaws 13. The distance adjustment assembly 142 enables multiple first mechanical clamping jaws 13 to move in conjunction, and only one distance adjustment cylinder 141 is required to complete the adjustment action of all first mechanical clamping jaws 13.

[0036] Reference Figure 7 The battery cell transfer mechanism 2 includes a Y-axis moving platform 21 and a battery cell fixing fixture 22. The Y-axis moving platform 21 is used to drive the battery cell fixing fixture 22 to move horizontally. The battery cell fixing fixture 22 is used to receive and fix the battery cell 200. It generally includes a bottom plate and guide limit blocks on both sides, which are used to support the battery cell 200 and position the battery cell 200 around. It also has a centering effect and plays a secondary positioning role for the battery cell 200.

[0037] Reference Figure 8 The plate swinging manipulator 3 includes a Z-axis lifting platform 31, a second mounting frame 32, and a plurality of second mechanical grippers 33. The Z-axis lifting platform 31 is used to drive the second mounting frame 32 to rise and fall. The plurality of second mechanical grippers 33 are arranged on the second mounting frame 32 to grasp and release the battery cell 200. The Z-axis lifting platform 31 has only a lifting function and does not have a horizontal movement function. The plate swinging manipulator 3 does not need to be provided with a variable pitch mechanism.

[0038] Reference Fig. 9 and Fig.10The second mechanical gripper 33 includes a second bidirectional opening and closing cylinder 331, a third battery cell pressing cylinder 332, a fourth battery cell pressing cylinder 333, a third L-shaped gripper 334 and a fourth L-shaped gripper 335. The second bidirectional opening and closing cylinder 331 is used to drive the third L-shaped gripper 334 and the fourth L-shaped gripper 335 to clamp and move away from each other to grab or release the battery cell 200. The third battery cell pressing cylinder 332 is used to press the battery cell 200 onto the third L-shaped gripper 334. The fourth battery cell pressing cylinder 333 is used to press the battery cell 200 onto the fourth L-shaped gripper 335. The only difference between the second mechanical gripper 33 and the first mechanical gripper 13 is that the rotating cylinder 131 is not provided, and the other structures are exactly the same. The third cell pressing cylinder 332 and the fourth cell pressing cylinder 333 can stably press the cell 200 onto the third L-shaped clamp 334 and the fourth L-shaped clamp 335 to prevent displacement during the lifting process, which affects the transfer accuracy, and can also prevent the cell 200 from falling.

[0039] The specific process of loading the material by the loading device of the present application is as follows: first, the YZ two-axis mobile platform 11 drives the first mechanical clamp 13 to descend to the position of the battery cell 200, the first two-way opening and closing cylinder 132 is actuated, the first L-shaped clamp 135 and the second L-shaped clamp 136 are clamped to grab the battery cell 200, and then the first battery cell pressing cylinder 133 and the second battery cell pressing cylinder 134 are actuated to press the battery cell 200; then the YZ two-axis mobile platform 11 drives the first mechanical clamp 13 and the battery cell 200 to rise, and then moves horizontally to the battery cell. The rotating mechanism 2 is above the rotating mechanism 2, and the battery cell 200 is placed on the battery cell fixing fixture 22. The first battery cell pressing cylinder 133 and the second battery cell pressing cylinder 134 are actuated, and the battery cell 200 is no longer pressed. The first two-way opening and closing cylinder 132 is actuated, and the first L-shaped clamp 135 and the second L-shaped clamp 136 are opened to release the battery cell 200. The YZ two-axis moving platform 11 drives the first mechanical clamp 13 to rise and return to the initial position; the Y-axis moving platform 21 drives the battery cell fixing fixture 22 to move horizontally to the bottom of the plate swinging robot 3; the plate swinging robot The Z-axis lifting platform 31 of the hand 3 drives the second mounting frame 32 and the plurality of second mechanical grippers 33 to descend. When the second two-way opening and closing cylinder 331 is actuated, the third L-shaped gripper 334 and the fourth L-shaped gripper 335 are clamped to grab the battery cell 200, and then the third battery cell pressing cylinder 332 and the fourth battery cell pressing cylinder 333 are actuated to press the battery cell 200; the Z-axis lifting platform 31 drives the second mounting frame 32 and the plurality of second mechanical grippers 33 to rise to avoid the heating tray 101 and the battery cell heating device 100. The fork mechanism pushes one of the heating trays 101 to a suitable distance, the Z-axis lifting platform 31 drives the second mounting frame 32 and multiple second mechanical grippers 33 to descend, so that the battery cell 200 is close to the heating tray 101, the third L-shaped gripper 334 and the fourth L-shaped gripper 335 separate, release the battery cell 200, and the battery cell 200 falls onto the heating tray 101 for contact heating; the Z-axis lifting platform 31 drives the second mounting frame 32 and multiple second mechanical grippers 33 to rise; the fork mechanism pulls the heating tray 101 back to the initial position. Repeat the above actions, and after the current heating tray 101 is filled, lay another heating tray 101 to achieve continuous loading and improve loading efficiency.

[0040] The implementation principle of the present application is as follows: the present application no longer uses a large-sized five-axis manipulator, but is provided with a material-retrieving manipulator 1, a battery cell transfer mechanism 2, and a plate-staggering manipulator 3. The material-retrieving manipulator 1, the battery cell transfer mechanism 2, and the plate-staggering manipulator 3 all have a shorter travel, a smaller size, and are easier to arrange; and the battery cell transfer mechanism 2 and the plate-staggering manipulator 3 are both single-axis moving mechanisms, with a simple structure and a simple moving trajectory, which greatly reduces the requirements for avoiding surrounding parts, and can be arranged very close to the heating tray 101, thereby reducing the size and floor space of the entire heating equipment. The material-retrieving manipulator 1, the battery cell transfer mechanism 2, and the plate-staggering manipulator 3 can grab multiple battery cells 200 at a time, and can also change the distance to reduce the distance between the battery cells 200, so that the heating tray 101 can accommodate more battery cells 200, thereby increasing production.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
