As shown in fig. 6 and 7, the drop prevention mechanism 2 includes:

two first supporting seats 21 are provided and fixedly connected to the supporting frame 1;

two second supporting seats 22 which slide vertically and are connected to the first supporting seats 21 in a one-to-one correspondence manner; in a specific embodiment, as shown in fig. 6 and 7, the second support seat 22 can slide vertically by a slide rail and a slide block: the slide rail is vertically fixed in first supporting seat 21, and slider and slide rail sliding connection, and the slider is fixed in second supporting seat 22. Of course, in other embodiments, other structures may be used to achieve vertical sliding.

Two first driving devices 23 are provided, and are fixedly connected to the first supporting seats 21 in a one-to-one correspondence manner, and output ends of the first driving devices are fixedly connected to the second supporting seats 22 in a one-to-one correspondence manner; in one embodiment, the first driving device 23 may be an actuator, such as a pneumatic cylinder.

The pocket bottom plate 24 is horizontally and transversely arranged and is horizontally and longitudinally connected with the two second supporting seats 22 in a sliding manner;

two second driving devices 25 are provided, and are fixedly connected to the second supporting seats 22 in a one-to-one correspondence manner, and output ends of the second driving devices are respectively and fixedly connected to the pocket bottom plates 24; in one embodiment, the second driving device 25 may be an actuator, such as a pneumatic cylinder.

Wherein, the two first supporting seats 21, the two second supporting seats 22, the two first driving devices 23, and the two second driving devices 25 are respectively arranged symmetrically with respect to the center line of the pocket bottom plate 24.

The principle of preventing battery cell 8 from dropping: after the clamping mechanism 4 clamps the battery cell 8, the first driving device 23 drives the second supporting seat 22 to move downwards, so that the pocket bottom plate 23 is lower than the bottom of the battery cell 8; then the second driving device 25 drives the pocket bottom plate 24 to move along the horizontal longitudinal direction and extend to the position right below the bottom of the battery cell 8; finally, the first driving device 23 drives the second supporting seat 22 to move upwards, so that the pocket bottom plate 24 is in contact with the bottom of the battery cell 8, the battery cell pocket bottom is supported, and the battery cell 8 can be prevented from dropping in the process of moving the battery cell 8.

In the embodiment shown in fig. 8, the foam pressing mechanisms 3 are symmetrically arranged with respect to a center line of the foam pressing rod 34, and the foam pressing mechanisms 3 include:

two third supporting seats 31 are provided and fixedly connected to the supporting frame 1;

two fourth supporting seats 32, which are vertically slid and connected to the third supporting seat 31 in a one-to-one correspondence; in a specific embodiment, the fourth supporting seat 32 is also vertically slidably connected to the third supporting seat 31 through a sliding rail and a sliding block. Wherein, the slide rail is vertically fixed on the fourth supporting seat 32; the sliding block is fixed on the third supporting seat 31 and is connected with the sliding rail in a sliding way.

Two third driving devices 33 are provided, and are fixedly connected to the third supporting seat 31 in a one-to-one correspondence manner, and output ends of the third driving devices are fixedly connected to the fourth supporting seat 32 in a one-to-one correspondence manner, so that the fourth supporting seat 32 is driven to vertically slide, and thus, the vertical position of the first detecting device 35 is adjusted, and whether each electric core is flush or not is detected in advance; in a specific implementation, the third driving device 33 may employ an actuator, such as a cylinder.

The foam compression bar 34 is connected with the two third supporting seats 31; the foam pressing rod 34 is used for pressing packaging protection materials such as foam or polystyrene for placing the battery cell 8, so that the battery cell 8 is conveniently clamped, and the foam or polystyrene is prevented from being brought up in the process of clamping the battery cell 8.

The first detection device 35 is fixedly connected to the fourth support seat 32, and is configured to detect whether each to-be-clamped battery cell 8 is horizontally level; the reason why the first detecting device 35 is to be provided to detect whether each of the battery cells 8 to be clamped is level, i.e. equal in height, is that: when the battery cell 8 is clamped into the groove of the foam, generally, in order to avoid the battery cell 8 from moving in the groove, the battery cell 8 and the groove generally adopt transition fit or interference fit, and therefore, when the battery cell 8 is inserted into the groove, it may happen that the battery cell 8 is not inserted in place, so that the battery cell 8 is tilted, that is, the rest of the battery cells 8 inserted in place are protruded in the height direction, and therefore when the clamping mechanism 4 clamps the battery cell 8, the battery cell which is not inserted in place may interfere with and collide with the clamping mechanism 4 due to the protrusion in the height direction, and the battery cell 8 or the clamp of the invention is damaged, thereby causing potential safety hazards.

In a specific embodiment, the first detecting device 35 employs a correlation sensor, and there are two corresponding edges on the top end of the battery cell 8, which are used because: when the battery cell 8 is inserted in place, one side of the top end of the battery cell may be high, and the other side of the battery cell may be low, if only one battery cell is used, the height detected by the side which is possibly low is that the surface of the battery cell is inserted in place, and is equal to the height of other battery cells 8, so that two battery cells are arranged on two sides of the top end of the battery cell 8, and false detection is avoided. The correlation sensor comprises a transmitter 351 and a receiver 352, and when the normal battery cell 8 is inserted in place, the receivers 352 of the two correlation sensors can both receive signals sent by the generator 351; if the battery cell 8 is not inserted in place, at least the high side interrupts the signal from the corresponding transmitter 351 and cannot be received by the receiver 352, thereby triggering a predetermined protection mechanism when the battery cell 8 is not inserted in place.

When the cell 8 is clamped and lifted upwards, the spring 39 provides elasticity to push the foam pressing rod 34 to continuously press the packaging materials such as foam or Styrofoam, so that the cell 8 and the foam are separated, and the packaging materials such as the foam cannot be taken up.

The two connecting blocks 38 are fixedly connected to two ends of the foam pressing rod 34 in a one-to-one correspondence manner;

the two fifth supporting seats 36, the two vertical guide rods 37 and the two connecting blocks 38 are respectively arranged symmetrically with respect to the center line of the foam pressing rod 34.

Therefore, the horizontal and longitudinal positions of the foam pressing rod 34 can be adjusted to adapt to packaging materials of foam or Styrofoam and the like with different specifications.

The principle of pressing foam is as follows: the horizontal longitudinal position of the foam pressing rod 34 is adjusted by an adjusting bolt (not shown) so that the foam pressing rod can press foam and cannot press the battery cell 8. When centre gripping electricity core, earlier by third drive arrangement 33 drive fourth supporting seat 32 lapse, drive first detection device 35 downstream and target in place, detect whether parallel and level of each electric core, behind the parallel and level, anchor clamps by the robot drive to drive the cotton depression bar of bubble 34 downstream, push down the package material such as cotton or Polylon of bubble, then 4 centre gripping electric cores 8 of clamping mechanism have again, and press from both sides electric core 8, later drive by the robot anchor clamps centre gripping electric core 8 remove, and reset by third drive arrangement 33 drive fourth supporting seat 32 upwards earlier, reset first detection device 35.
