[0028] Please refer to Figures 1 to 6 , a box transfer assembly, comprising: two gantry guide beams 11; a transverse guide beam 12, the transverse guide beam 12 spans between the two gantry guide beams 11, a hoisting member 13 is provided on the transverse guide beam 12, a grasping portion 14 for grasping a box (not shown in the figure) is configured on the hoisting member 13, the hoisting member 13 is used to drive the grasping portion 14 to move longitudinally, and the grasping portion 14 can rotate relative to the hoisting member 13 in a plane parallel to the tray. In this embodiment, the transverse guide beam 12 can move along the extension direction of the gantry guide beam 11, that is, the second direction Y, and the hoisting member 13 can move along the extension direction of the transverse guide beam 12, that is, the first direction X. Therefore, after the grasping portion 14 grasps the box, it can move in three-dimensional space to transport the box to a designated position. At the same time, the rotation of the grasping portion 14 in a plane parallel to the tray can accurately adjust the angle of the box, facilitating the reverse buckling assembly of the box and the module.

[0029] Further, as Figures 3 to 5 shown, the grasping portion 14 includes a main body frame 141. A fixed plate 142 is provided on a side surface of the main body frame 141 facing the tray. A double-headed screw rod 144 is rotatably installed on the fixed plate 142. Both end plates of the double-headed screw rod 144 are threadedly connected with a clamping portion 143. The clamping portion 143 is slidably connected to the main body frame 141. The double-headed screw rod 144 drives the two clamping portions 143 to approach or move away from each other. In this embodiment, the double-headed screw rod 144 is driven by a motor to synchronously drive the two clamping portions 143 to move. In other embodiments, the two clamping portions 143 can also act asynchronously, that is, they can be respectively driven by screw rods. When in use, first adjust the grasping portion 14 so that it is above the box, then drive the grasping portion 14 to approach the box longitudinally through the hoisting member 13, so that the two clamping portions 143 are in the grasping position, and then drive the two clamping portions 143 to approach synchronously through the double-headed screw rod 144 to hook the box.

[0030] Furthermore, the clamping part 143 includes a moving plate 1431 which is in threaded driving connection with a double-headed lead screw 144, and the moving plate 1431 is slidably connected to the main body frame 141 through a slide rail-slider assembly; a clamping jaw for hooking the box body is arranged on the moving plate 1431. Further, the clamping jaw includes a fixed frame body 1432, and a jaw body 1433 is movably installed on the fixed frame body 1432, and the jaw body 1433 can move longitudinally relative to the fixed frame body 1432. The fixed frame body 1432 is fixedly installed on the moving plate 1431, and the jaw body 1433 is slidably connected to the fixed frame body 1432 through a slide rail-slider assembly, and a second driving member 1434 for driving the jaw body 1433 is arranged on the moving plate 1431 or the fixed frame body 1432. The second driving member 1434 includes, but is not limited to, a cylinder, a hydraulic cylinder or an electric push rod.

[0031] Specifically, the jaw body 1433 is L-shaped, a fixing pin 14331 is arranged at the bottom of the jaw body 1433, the fixing pin 14331 extends vertically upward, and a fixing hole corresponding to the fixing pin 14331 is arranged on the box body. Here, the jaw body 1433 is lifted vertically upward by the second driving member 1434 so that the fixing pin 14331 is inserted into the fixing hole to complete the fixing of the box body, and the stability of the box body during the lifting and handling process is improved.

[0032] An extension frame 145 is arranged on the moving plate 1431, a transfer pin 146 is arranged on the extension frame 145, and the transfer pin 146 extends in the direction away from the box body of the jaw body 1433; a transfer hole adapted to the transfer pin 146 is arranged on the sub-tray. During use, when the battery box body is transferred to the battery module and put into the box, the transfer pin 146 is inserted into the transfer hole during the process of the jaw body 1433 disengaging from the box body, so as to facilitate the subsequent handling of the sub-tray and the battery pack.

[0033] An anti-fooling long pin 16 is arranged on the main body frame, an anti-fooling hole adapted to the anti-fooling long pin 16 is arranged on the sub-tray, the anti-fooling long pin 16 is slidably connected to the main body frame, a first spring 18 is sleeved outside the anti-fooling long pin 16, the first spring 18 is pressed between the anti-fooling long pin 16 and the main body frame, and an induction component 19 for sensing the anti-fooling long pin 16 is arranged on the main body frame. Specifically, as Figure 3 and Figure 5As shown in the figure, an anti-fooling frame 17 is arranged on the main frame body. The upper end of the anti-fooling long pin 16 is slidably installed on the anti-fooling frame 17 through a linear bearing. A guiding frame 171 is arranged on the anti-fooling frame 17. The upper end of the anti-fooling long pin 16 penetrates through the guiding frame 171. The sensing component 19 is installed on the anti-fooling frame 17 or the guiding frame 171 and is used to sense the position change of the upper end of the anti-fooling long pin 16. A shoulder is arranged at the upper end of the anti-fooling long pin 16, and the first spring 18 is sleeved between the shoulder and the guiding frame 171. During use, when the assembly is successful, the anti-fooling long pin 16 is accurately assembled into the anti-fooling hole, and the equipment operates normally to the next step; when the gripping part 14 or the posture of the box body is not standardized, the anti-fooling long pin 16 is misaligned with the anti-fooling hole. During the downward movement along the longitudinal direction, the anti-fooling long pin 16 is blocked and moves upward. At this time, the sensing component 19 receives this signal, and the equipment does not continue to move downward but adjusts its posture to prevent the equipment from crashing. The first spring 18 here is used to reset the anti-fooling long pin 16.

[0034] As Figure 4 and Figure 6 shown in the figure, a buffer plate 147 is arranged on the fixed plate 142. The buffer plate 147 can move longitudinally relative to the fixed plate 142.

Specifically, an extension plate 149 is arranged on the fixed plate 142, and a guiding rod is arranged on the buffer plate 147. The guiding rod is slidably installed on the extension plate 149 through a linear bearing. A buffer frame 148 is arranged on the extension plate 149 or the fixed plate 142, and a second spring is pressed between the buffer frame 148 and the buffer plate 147. The second spring here is the aforementioned damping member 1481. During the process of the battery entering the box, the box body first abuts against the buffer plate 147 after being stressed. The buffer plate 147 can provide a buffer distance for the box body before it abuts against the fixed plate 142, avoiding damage to the box body due to hard contact.

[0035] In this embodiment, as Figure 2 shown in the figure, the hoisting member 13 is movably installed on the transverse guide beam 12 through a slide plate. Specifically, the hoisting member 13 includes a hanging column 131 and a first driving member 133 arranged on the slide plate.
