The loading platform 3 is provided with multiple groups of buffer mechanisms for positioning battery cell units in parallel, and each group of buffer mechanisms is fixedly connected to the loading platform 3 through a group of supporting plates 6. Figure 1 and Figure 2 As shown, the number of cache mechanisms on the loading platform 3 is six groups.

[0026] In this embodiment, the feeding linear module includes a first push-pull cylinder 4 arranged at the bottom of the feeding platform 3, and the feeding platform 3 is connected to the output shaft of the first push-pull cylinder 4; the feeding platform 3 is also provided with a first guide rail 5 extending in the same direction as the first push-pull cylinder 4, and the bottom of the feeding platform 3 is slidably connected to the first guide rail 5 through a first slider.

[0027] like Figure 3 As shown, the cache mechanism includes a cache plate 7 supporting the battery cell unit, and pressure plates 8 arranged in parallel on both sides of the cache plate 7. A plurality of parallel cylinders 9 are arranged along the length direction at the bottom of the cache plate 7. Two output jaws of the parallel cylinders 9 are arranged along the width direction of the cache plate 7 and are respectively connected to the two groups of pressure plates 8 to drive the two groups of pressure plates 8 to move towards and away from the cache plate 7.

[0028] A plurality of groups of second guide rails 10 extending along the width direction of the buffer plate 7 are arranged side by side at the bottom of the buffer plate 7 , and two groups of pressure plates 8 are slidably connected to the second guide rails 10 via second sliders.

[0029] The purpose of the utility model is to provide a battery cell unit buffer device that is easy to load, so that the loading robot 2 can be used for clamping. The utility model provides a buffer plate 7 to place the battery cell units to be stacked, and then controls the relative movement of two sets of pressing plates 8 through parallel cylinders 9 to press the battery cell units from both sides. The opposite end surfaces of the two sets of pressing plates 8 are arranged with multiple flexible pads 13 to prevent the battery cell units from being crushed during the pressurization process.

[0030] Furthermore, a pressure regulating valve 11 for adjusting the air pressure of the parallel cylinder 9 is provided on the supporting plate 6 to change the pressure applied by the pressing plate 8 to the battery cell unit.

[0031] A reference block 12 is installed at one end of the buffer plate 7 and abuts against the side of the battery cell unit. The battery cell unit is placed on the buffer plate 7 and the end of the battery cell unit is abutted against the reference block 12. The reference block 12 and the pressure plates 8 on both sides work together to limit the movement of the battery cell unit.

[0032] In order to be compatible with battery cells of different lengths, the flexible pad 13 is configured as a long pad at one end close to the reference block 12 and a short pad at one end away from the reference block 12; the height of the long pad is the same as the height of the battery cell, so that the long pad is in full contact with the side of the battery cell and exerts sufficient clamping force; the short pad is to avoid the water cooling pipe at the end of the battery cell to prevent the water cooling pipe from being crushed.

[0033] Furthermore, a photoelectric sensor assembly 14 is provided on the side of the pressing plate 8, and the photoelectric sensor assembly 14 is located near the reference block 12 and aligned with the central axis of the water cooling tube. The first photoelectric sensor can determine whether the battery cell unit is grabbed by monitoring the position of the water cooling tube, thereby preventing the device from being fooled.

[0034] Furthermore, a proximity switch 15 is provided on the side of the pressing plate 8, and the proximity switch 15 is located in the middle of the side plate. The proximity switch 15 can detect whether there is a battery cell unit on the buffer plate 7, so as to accurately issue a material-taking instruction to the robot.

[0035] like Figure 2 As shown, in this embodiment, two groups of loading platforms 3 are stacked on the frame 1, and each group of loading platforms 3 is connected to the frame 1 through a group of loading linear modules. When one group of loading platforms 3 is finished loading, it returns to the initial position through the loading linear module to wait for new battery cells to be loaded; the other group of loading platforms 3 moves to the loading position to realize the rotation of the loading platforms 3. The number of loading platforms 3 is not limited to two groups in the embodiment, and can be set to more groups according to needs.

[0036] Furthermore, an over-height detector 16 is provided, which is connected to one set of the supporting plates 6 and is provided outside the height range of the battery cell unit. The over-height detector 16 can monitor the battery cell unit exceeding a predetermined height.

[0037] like Figure 4 and Figure 5 As shown, the loading robot 2 includes a gripper support plate 17 and a plurality of groups of fixed-end grippers 18 and movable-end grippers 19 arranged in pairs at the upper and lower ends of the gripper support plate 17, and a clamping space for grasping the battery cell unit is formed between the fixed-end grippers 18 and the movable-end grippers 19; a second push-pull cylinder 20 is fixedly arranged on the gripper support plate 17, and the movable-end gripper 19 is connected to the output shaft of the second push-pull cylinder 20 through a gripper connecting plate 27, and the movable-end gripper 19 is driven by the second push-pull cylinder 20 to move toward the fixed-end gripper 18.

[0038] The gripper support plate 17 is further provided with a fixed block 21 at the bottom of each group of mobile end grippers 19 , and a buffer spring 22 is provided between the fixed block 21 and the mobile end grippers 19 to provide sufficient buffer force when the loading robot 2 clamps the battery cell unit.

[0039] Compatible rails 23 extending along the length direction are also provided on both sides of the gripper support plate 17. The movable end clamping hands 19 and the fixed end clamping hands 18 located on both sides of the gripper support plate 17 are slidably connected to the compatible rails 23 through compatible sliders 24. The cooperation between the compatible sliders 24 and the compatible rails 23 can adjust the position of the clamping hands according to the specifications of different products.

[0040] Furthermore, a rail clamp 25 is provided at the bottom of the compatible slider 24 to lock the position of the compatible slider 24 after the clamp is in place.

[0041] The loading robot 2 further includes a six-axis robot 26 , and the gripper support plate 17 is connected to the output end of the six-axis robot 26 , and is driven by the six-axis robot 26 to grab the battery cell units from each buffer mechanism.
