[0038] The automatic feeding mechanism 6 is fixedly arranged on the upper end of the base 1 and is arranged on the lower side of the follow-up moving mechanism 2, and the automatic feeding mechanism 6 comprises a plurality of electric push rods 61 fixedly arranged on the upper end of the base 1, the upper end moving end of the plurality of electric push rods 61 is fixedly connected with the same lifting plate 62, the upper end of the lifting plate 62 is fixedly arranged with a belt conveyor 63, the upper end of the lifting plate 62 is fixedly connected with two L-shaped baffles 64, the horizontal part upper end of the L-shaped baffle 64 is fixedly arranged with a horizontal supporting roller roller group 65, and the vertical part side wall of the L-shaped baffle 64 is fixedly arranged with a vertical supporting roller roller group 66.

[0039] The operation principle of the present application is described as follows: when the whole device is in the initial position state, the moving seat 25 is located in the first fixed shell 23, at this time, the initial position limiting mechanism 5 limits and fixes the relative position of the moving seat 25, at this time, the limiting rod 51 cooperates with the stress block 54 to stretch out of the moving seat 25 under the elastic force of the return spring 55, and the limiting rod 51 is inserted into the limiting hole 52 in the side wall of the first fixed shell 23 to limit and fix the relative position of the moving seat 25.

[0040] Before the automobile battery installation is needed to be carried out, the PLC controller controls the deflection motor 22 to act, and the power supply to the electromagnetic magnetic attraction fixing assembly 28 is cut off synchronously, so that the first fixed shell 23 and the second fixed shell 24 are in the state of relative separation, the deflection motor 22 drives the first fixed shell 23 to rotate 180 degrees, so that the automatic assembly mechanism 3 is turned over to the lower side, at this time the automatic material distribution mechanism works, the belt conveyor 63 drives the battery installation plate 8 and the battery pack 9 to move, the two L-shaped baffles 64 cooperate with the horizontal supporting roller roller group 65 and the vertical supporting roller roller group 66 to limit the battery installation plate 8, so that the battery installation plate 8 drives the battery pack 9 to move accurately to the lower side of the automatic assembly mechanism 3, and then the battery installation plate 8 and the battery pack 9 are pushed up by the electric push rod 61, so that the locking seat 42 on the battery installation plate 8 moves to one side of the locking plate 45, the PLC controller controls the double-shaft motor 43 to act, the double-shaft motor 43 drives two rotating screws 44 to rotate synchronously, and then the rotating screws 44 and the locking plate 45 are screwed together, so that the locking plate 45 drives a plurality of plug-in rods 46 to move towards the locking seat 42, so that the plug-in rods 46 are inserted into the plug-in holes 47 in the side wall of the locking seat 42, so that the lifting plate 32 and the battery installation plate 8 are stably connected together, and at this time the end of the positioning bolt 10 is in contact with the connecting electromagnetic block 37, the PLC controller controls the deflection motor 22 to drive the first fixed shell 23 to turn over 180 degrees, so that the automatic assembly mechanism 3 drives the battery installation plate 8 and the battery pack 9 to turn over to the upper side;

[0041] When the vehicle body holder enters the battery mounting station, the PLC controller controls the power supply device to supply power to the suction electromagnetic plate 57, and the suction electromagnetic plate 57 generates magnetic force opposite to the suction permanent magnet plate 56, thereby providing an attractive force to the force block 54 and the limiting rod 51, and then the limiting rod 51 moves into the storage slot 53, the limiting rod 51 is separated from the limiting hole 52, thereby releasing the limiting locking of the moving seat 25, the PLC controller controls the electric gear assembly 26 to work, and the electric gear assembly 26 cooperates with the fixed rack 27 to drive the moving seat 25 to displace, forming a speed opposite to the vehicle body holder, thereby making the battery pack 9 and the vehicle body holder keep a relative static state, and the battery pack 9 is aligned with the battery mounting position, at this time the PLC controller controls the power supply device to supply power to the connecting electromagnetic block 37, and the connecting electromagnetic block 37 generates magnetic force to stably magnetically connect the positioning bolt 10, the PLC controller controls the servo motor 35 to act, the servo motor 35 drives the plurality of transmission shafts 33 to synchronously rotate through the bevel gear assembly 36, the transmission shaft 33 drives the connecting electromagnetic block 37 and the plurality of positioning bolts 10 to synchronously rotate through the locking force feedback mechanism 7, so that the positioning bolt 10 is connected relative to the vehicle body, and the battery pack 9 is fixedly mounted, and in the process of tightening the bolt, the locking force feedback mechanism 7 drives the plurality of lifting screws 38 to synchronously rotate through the transmission gear assembly 310, and then the lifting screws 38 and the fixed screw cylinder 39 are threadedly connected to make the lifting plate 32 push the battery pack 9 to synchronously move towards the vehicle body, matching the displacement amount generated by the installation of the battery pack 9;

[0042] After the positioning bolt 10 is installed to the final position, as the transmission shaft 33 continues to rotate, the positioning bolt 10 cannot continue to rotate, which causes the linkage shaft 72 to drive the connecting electromagnetic block 37 to deflect relative to the synchronous circular shell 71, so that the torsion spring 73 generates deformation to provide greater torque rotating force, until the linkage shaft 72 produces enough deflection distance relative to the synchronous circular shell 71, so that the arc-shaped trigger block 75 connected to the linkage shaft 72 presses the feedback switch 74 on one side of the inner wall of the synchronous circular shell 71, indicating that the current positioning bolt 10 is installed in place, and the torque reaches the most appropriate range, at this time the PLC controller controls the power supply device to cut off the power supply to the current connecting electromagnetic block 37, so that the transmission shaft 33 no longer drives the positioning bolt 10 to rotate, avoiding the problem that the installation of the positioning bolt 10 generates too large torque to cause the positioning bolt 10 to break and be damaged, until all the positioning bolts 10 are fixed in place, all the feedback switches 74 are pressed and triggered, indicating that the battery pack 9 is installed, at this time the PLC controller controls the double-shaft motor 43 to reverse, so that the plug-in rod 46 is separated from the locking seat, thereby contacting the limiting connection of the battery mounting plate 8, and the PLC controller controls the servo motor 35 to reverse, so that the lifting plate 32 is reset to the initial position, and the PLC controller controls the electric gear assembly 26 to rotate back, so that the moving seat 25 moves into the first fixed shell 23 again;

[0043] And in the process of moving back to the reset of the mobile seat 25, the PLC controller breaks the power supply to the suction electromagnetic plate 57, the limit rod 51 in the state of losing the magnetic force, using the resilience of the reset spring 55 to make the limit rod 51 again into the mobile seat 25 outside, because the limit rod 51 has not moved to the limit hole 52, at this time the limit rod 51 is in contact with the sliding in the first fixed shell 23 and the second fixed shell 24 of the inner side wall, until the limit rod 51 moves to the limit hole 52 in the first fixed shell 23, at this time the limit rod 51 is inserted into the limit hole 52 to limit the locking of the mobile seat 25, indicating that the mobile seat 25 has also moved to the accurate initial position at this time, because the mobile seat 25 cannot continue to move at this time, the output torque of the electric gear assembly 26 reaches the threshold value and automatically stops working, completing the moving work of the mobile seat 25;

[0044] The above steps are repeated to complete the continuous new energy automobile battery assembly work.

[0045] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
