[0045] In order to clearly illustrate the technical features of this patent, this patent is elaborated in detail below through a specific implementation method and in combination with its accompanying drawings.

[0047] The water-cooled plate flip assembly 4 includes a mounting plate 41, a flip plate 42, a suction cup 43, a rotation power source 44 and a correction assembly 45;
[0048] The cache table 2 is fixedly mounted with a cache table guide rail 21 arranged along the X direction and a first linear power source 22. The mounting plate 41 is arranged along the Y direction and is slidably mounted on the cache table guide rail 21. The mounting plate 41 is driven by the first linear power source 22 to reciprocate along the X direction on the cache table 2. The two ends of the flip plate 42 are rotatably connected to the mounting plate 41, and a plurality of suction cups 43 are arranged on the front of the flip plate 42 facing the battery core reference positioning assembly 5. The rotating power source 44 is mounted on the mounting plate 41. On the flip plate 42, and connected to the flip plate 42, the flip plate 42 is driven to flip back and forth by the rotating power source 44; a plurality of correction components 45 perpendicular to the flip plate 42 are also installed, and the correction components 45 include a correction cylinder 451 fixedly connected to the back of the flip plate 42 and a correction stopper 452 fixedly connected to the cylinder rod of the correction cylinder 451, and the correction stopper 452 extends to the front of the flip plate 42, and the correction stopper 452 is driven by the correction cylinder 451 to make a straight reciprocating motion perpendicular to the flip plate 42. In this way, after the water-cooled plate in a vertical state is grabbed and placed by the robot, the water-cooled plate can be sucked by the suction cup, and then the water-cooled plate is driven to flip to a horizontal state. When the water-cooled plate is laid flat, the suction of the suction cup is removed, and then the water-cooled plate is moved by the correction stopper 452 to correct its position. After accurate correction, the water-cooled plate is sucked and flipped to a vertical state.
[0049] The battery cell group is also grabbed by the robot and placed on the cache table 2 and against the battery cell reference positioning assembly 5. During bonding, the first linear power source 22 drives the mounting plate 41 on the cache table 2 to approach the battery cell reference positioning assembly 5 along the X direction and maintain it, thereby completing the bonding of the battery cell group and the water cooling plate.
[0050] The mounting plate 41 is also provided with a visual verification component, which includes a light source 46 and a camera 47 fixedly mounted on the mounting plate 41. In this way, the water cooling plate or the battery module can be turned up to a horizontal state before the water cooling plate is bonded, and then photographed by the camera to determine whether the water cooling plate is calibrated and whether the battery module is bonded.
[0051] The first linear power source 22 is a linear electric cylinder, the cylinder body of which is fixedly mounted on the bottom surface of the buffer table 2, a driving block is fixedly connected to the bottom surface of the mounting plate 41, and the output rod of the linear electric cylinder is connected to the driving block. Thus, the mounting plate 41 is driven by the linear electric cylinder to reciprocate along the X direction on the buffer table 2.
[0052] The rotary power source 44 includes a servo motor 441 , a reducer 442 and a coupling 443 . The servo motor 441 is fixedly mounted on one end of the mounting plate 41 , and its output shaft is connected to the flip plate 42 via the reducer 442 and the coupling 443 .

[0054] The second linear power source 53 is a push plate cylinder, the cylinder body of which is fixedly connected to the fixed vertical plate 51 through a bracket, and the cylinder rod of which penetrates the fixed vertical plate 51 and is fixedly connected to the battery push plate 52. Thus, the battery push plate 52 is driven to reciprocate along the X direction by the push plate cylinder, and it should be noted that the cylinder rod is not shown in the figure.
[0055] The buffer table 2 is connected to the frame 1 via an X-direction traveling assembly 3, and the X-direction traveling assembly 3 drives the buffer table 2 to reciprocate along the X-direction of the frame 1, thereby performing transfer between the loading and unloading stations.
[0056] The X-axis traveling assembly 3 includes an X-axis rack 31, an X-axis guide rail 32, a traveling gear 33 and a gear driving mechanism 34. The X-axis rack 31 and the X-axis guide rail 32 are both fixedly mounted on the frame 1 along the X-axis. The cache table 2 is slidably mounted on the X-axis guide rail 32. The traveling gear 33 is rotatably connected to the cache table 2 and meshes with the X-axis rack 31. The gear driving mechanism 34 is mounted on the cache table 2 and connected to the traveling gear 33. The traveling gear 33 is driven to rotate by the gear driving mechanism 34.
[0057] The gear driving mechanism 34 includes a motor, a reducer and a transmission connecting rod. The motor is fixedly mounted on the cache table 2, and the output shaft of the motor is connected to the travel gear 33 via the reducer and the transmission connecting rod.
[0058] To ensure stability during walking, two X-axis racks 31, two X-axis guide rails 32, two travel gears 33 and two transmission connecting rods are provided. The reducer has an input end connected to the motor and two output ends respectively connected to the two transmission connecting rods, so that the two travel gears are driven to rotate synchronously by the motor at the same time to stably realize the X-axis walking of the cache table.
[0059] In order to further improve the efficiency, two upper and lower buffer tables 2 are arranged on the frame 1 so that the two can operate alternately between the loading and unloading stations, thereby doubling the processing efficiency.
[0060] There are many specific implementation ways of the present invention. The above is only the preferred implementation mode of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements can be made without departing from the principle of the present invention. These improvements should also be regarded as the protection scope of the present invention.
