[0036] In this embodiment, the lifting structure includes a power element and a threaded rod 17. The threaded rod 17 is movably mounted on the mounting frame 1. The power element is mounted on the mounting frame 1 and its output end is connected to the threaded rod 17.

The mounting base 22 has a notch 30 formed on it that is adapted to the spring storage tube 21. When the push spring assembly is working, it assembles a single spring into the lock cylinder housing 2.

[0043] In practical applications, based on the structure of the car key, the lock plates are placed into the lock plate box 15 from the plate release port 20 according to the set arrangement order and stacked. At the same time, the springs are stored in the spring storage tube 21. The controller 4 controls the first electric telescopic rod 23 to be energized, thereby driving the lock plate box 15 and the assembly box to move.

[0045] In this embodiment, the feeding structure includes a guide seat 37, a counterweight seat 38, a pusher ring 35, and a pusher arm 36. The guide seat 37 is mounted on the spring rod 27 and the two are arranged perpendicularly. The pusher ring 35 is movably sleeved on the spring rod 27. The counterweight seat 38 is movably mounted on the guide seat 37 and is movably connected to the pusher ring 35 through the pusher arm 36. A spring 28 is mounted on the fixed seat 26. The starting end of the spring 28 is connected to the counterweight seat 38. A fixed pulley 29 is movably mounted on the fixed seat 26. The spring 28 and the fixed pulley 29 are in sliding engagement.

[0046] In practical applications, the springs required for lock cylinder assembly are stacked in the spring storage tube 21, with the lowest spring resting on the spring stopper rod 27. By controlling the operation of the first electric telescopic rod 23, the assembly seat 22 is driven to retract relative to the third electric telescopic rod 41, thereby driving the moving seat 31 to move along the fixed seat 26. Under the action of the pull arm 34, the spring stopper rod 27 can be driven to rotate along its hinge, thereby causing the spring stopper rod 27 and the guide seat 37 to rotate 90°. At this time, under the gravity of the counterweight seat 38, the counterweight seat 38 moves along the guide seat 37 and, under the action of the push arm 36, drives the push ring 35 to move along the spring stopper rod 27, thereby pushing the spring sleeved on the spring stopper rod 27 into the lock cylinder housing 2. By controlling the lifting seat 18 to rise and fall, the springs are installed in different positions on the lock cylinder housing 2.

[0047] Please see Figure 1 , Figure 6 , Figure 7 as well as Figure 8 As another preferred embodiment of this application, the feeding structure further includes a locking unit and a triggering unit. The locking unit is disposed between the counterweight 38 and the guide seat 37 to fix the position of the counterweight 38. The triggering unit is disposed between the movable seat 31 and the fixed seat 26 to monitor the position of the movable seat 31 and control the operation of the locking unit.

[0048] In one specific embodiment, the locking unit includes a first electromagnetic block 39 and several second electromagnetic blocks 40. The first electromagnetic block 39 is disposed on a counterweight 38, and the several second electromagnetic blocks 40 are equidistantly disposed on a guide seat 37. Both the first electromagnetic block 39 and the several second electromagnetic blocks 40 are trapezoidal structures, and the inclined surfaces of the first electromagnetic block 39 and the second electromagnetic blocks 40 are arranged in parallel.

The pressure sensor 33 is disposed on the fixed base 26 and located on the moving path of the other end of the abutment rod 32. The pressure sensor 33 is electrically connected to the locking unit.

[0050] It should be noted that this embodiment is not limited to the cooperation of the pressure sensor 33 and the abutment rod 32 to detect the position of the moving seat 31. Infrared ranging sensors or laser ranging sensors can also be used instead, which will not be listed here.

[0051] In practical applications, by controlling the energization of the first electromagnetic block 39 and the second electromagnetic block 40 and their mutual repulsion, the position of the counterweight 38 can be fixed. When the third electric telescopic rod 41 controls the moving seat 31 to move along the fixed seat 26 and meet the abutment rod 32, that is, the spring rod 27 rotates 90° and faces the lock cylinder housing 2. At this time, the abutment rod 32 is driven to rotate along its hinge and apply pressure to the pressure sensor 33. The pressure sensor 33 controls the first electromagnetic block 39 and the second electromagnetic block 40 to be de-energized through the controller 4. Under the gravity of the counterweight 38, the counterweight 38 moves down along the guide seat 37, and under the action of the push arm 36, it drives the push ring 35 to move along the spring rod 27, thereby pushing the spring into the lock cylinder housing 2.
