The support 9 comprises a support base 901, a slider 902 mounted in the support base 901, and a support spring 903 below the slider 902. In a free state, a support spring 903 supports the floating block 902 upwards, the floating block 902 is blocked and limited by the support seat 901, and when the floating block 902 is stressed downwards, the floating block 902 moves downwards.

After the pressing block 103 presses the metal terminal and is subjected to a downward external force, the cutter 101 may cut the metal terminal. Because the metal terminals are thinner, when the coiled material (which is laid flat) of the metal terminals is conveyed from the rear end, the coiled material of the metal terminals at the front end is slightly moved downwards under stress, the cutter 101 and the platform of the conveying platform 20 for conveying the coiled material are staggered, and the cutter 101 applies downward force to cut off the coiled material.

The lifting assembly 104 further includes a floating platform 1042 mounted on the slider 4, the floating platform 1042 is fixed to a side of the slider 4, the floating platform 1042 includes a mounting block 1421 fixed to the slider 4, the mounting block 1421 has a receiving hole (not shown) penetrating through upper and lower surfaces thereof, the floating platform 1042 further includes a moving column 1423 received in the receiving hole (not shown), a limiting block 1424 fixed below the moving column 1423, a pressing table 1425 mounted above the moving column 1423, and a pressing spring 1426 mounted between the pressing table 1425 and the mounting block 1421.
The movable column 1423 is a T-shaped structure with a large upper part and a small lower part, the lower end of the movable column 1423 penetrates through the accommodating hole, when the movable column 1423 is pressed downwards, the large surface of the movable column 1423 abuts against the upper surface of the mounting block 1421, the effect that the movable column 1423 cannot move downwards excessively is achieved, and meanwhile when the metal terminal is cut, the movable column 1423 can also be supported. In a free state, the pressing spring 1426 supports the pressing table 1425, and the stopper 1424 contacts the blocking mechanism 1041 to restrict excessive upward movement thereof.
The stopper 1424 includes a stopper surface 14241 with different heights, the floating platform 1042 is not pressed upward, and the stopper surface 1241 abuts against the bearing 1412 to limit the height of the floating platform 1042. In the initial position, the bearing 1412 is at the lower stop surface 14241. As the floating platform 1042 advances, the bearings 1412 roll along the stop surfaces 14241.
The metal terminal coil 40 is transferred to the floating platform 1042 by the transfer device 30.
As shown in fig. 5, the terminal cutting and inserting device 100 is in an initial position, the metal terminal coil 40 is conveyed to the floating platform 1042, the press block 103 is located above the metal terminal coil 40, the first toggle block 71, the second toggle block 72, and the third toggle block 73 are respectively located at the foremost sides of the first pushing hole 81, the second pushing hole 82, and the third pushing hole 83, the second stopper 62 is located on the surface of the slider 902 and does not apply downward pressure to the slider 902, the third stopper 63 is located at the rear side of the slider 902, and the slider 902 stops the third stopper 63 from moving forward.
When the device works, the pushing cylinder 3 is started, and the pushing cylinder 3 pushes the pushing block 8 to move forwards until the second position is reached. As shown in fig. 6, in the second position, since the floating block 902 blocks the third limiting block 63, the sliding block 4 cannot move forward, and meanwhile, due to the pushing force of the pushing cylinder 3, the pushing block 8 moves forward, the first toggle block 71 moves along the track of the first pushing hole 81, and finally the first limiting block 61 is driven to move downward along the first placing cavity 45, so as to drive the connecting seat 102 and the pressing block 103 to move downward until the second position is reached. The press block 103 presses the metal terminal at this time. The first toggle block 71, the second toggle block 72 and the third toggle block 73 are located at the tail ends of the first inclined hole 811, the third inclined hole 821 and the second transverse hole 831, the second toggle block 72 moves downwards along the second placing cavity 46, and the second limiting block 62 compresses the supporting spring 903 downwards.
The pushing cylinder 3 pushes forwards again, the first toggle block 71 moves along the track of the second inclined hole 812 to drive the pressing block 103 to move downwards, the floating platform 1042 bears downward pressure, meanwhile, the pressing spring 1426 presses upwards to support the force, the cutter 101 moves downwards along with the pressing block 103 until being used for moving the column 1423 to support the mounting block 1421, so that the cutter 101 and the conveying platform 20 form dislocation, the coiled material can be easily cut off by combining the sharp cutting edge of the cutter 101, at the moment, the third toggle block 73 moves along the track of the fourth inclined hole 832 inclined upwards to drive the third limiting block 63 to move upwards along the third placing cavity 47 until the lower end of the third limiting block 63 is flush with the floating block 902. At this time, the first toggle block 71, the second toggle block 72, and the third toggle block 73 are respectively located at the rearmost sides of the first push hole 81, the second push hole 82, and the third push hole 83, as shown in fig. 7, and reach a third position. The second stopper 62 continues to compress the support spring 903 downward.
As shown in fig. 8, the pushing cylinder 3 is pushed forward to reach the fourth position, because the first toggle block 71, the second toggle block 72, and the third toggle block 73 are respectively located at the rear sides of the first pushing hole 81, the second pushing hole 82, and the third pushing hole 83, and the front sides of the second limiting block 62 and the third limiting block 63 are not blocked by the floating block 902, when the pushing forward is performed, the first limiting block 61, the second limiting block 62, and the third limiting block 63 push the sliding block 4 to move forward, the pressing block 103 and the floating platform 1042 move forward, and the cut terminal is inserted into the plastic part at the preset position by the forward pushing force. In the process, the front sides of the second limiting block 62 and the third limiting block 63 are not blocked by the slider 902, the second limiting block 62 and the third limiting block 63 move forwards, the second limiting block 62 moves in front of the slider 902, the second limiting block 62 is separated from the slider 902 due to the thrust of the support spring 903, the slider 902 moves upwards, so that the slider 902 can block the second limiting block 62 from moving backwards, and the third limiting block 63 is still above the slider 902.
After the insertion of the metal terminal is completed, the pushing cylinder 3 pulls the pushing block 8 backward, as shown in fig. 9, to a fifth position. The first toggle block 71, the second toggle block 72 and the third toggle block 73 move along the tracks of the first pushing hole 81, the second pushing hole 82 and the third pushing hole 83 in opposite directions, when the first toggle block 71 moves to the foremost end of the first pushing hole 81, the first limiting block 61 drives the pressing block 103 to move upwards so as to be separated from the metal terminal, the second limiting block 62 is lifted along with the second pushing hole 82, the lower end of the second limiting block is flush with the floating block 902, and the third limiting block 63 moves downwards so as to compress the floating block 902.
The pushing cylinder 3 continues to pull the pushing block 8 backwards to return to the initial position. Because the second and third stoppers 62 and 63 are not blocked at the rear, the slider 4 moves backward by the tension transmission until it returns to the initial position. The second stopper 62 is located behind the surface of the slider 902, the slider 902 is not compressed by the second stopper 62, the third stopper 63 is separated from the surface of the slider 902, and the slider 902 is moved upward by the support spring 903, so that the forward movement of the third stopper 63 can be stopped.
Therefore, the metal terminal cutting and inserting device is structurally provided with the sliding block 4, the pushing block 8, the limiting blocks (the first limiting block 61, the second limiting block 62 and the third limiting block 63), the poking blocks (the first poking block 71, the second poking block 72 and the third poking block 73) and the pushing holes (the first pushing hole 81, the second pushing hole 82 and the third pushing hole 83), and the pushing block is pushed and pulled through a power mechanism, so that the sliding block, the pushing block and the limiting blocks are matched with each other to complete the work of cutting and inserting the metal terminal. The whole terminal cutting and inserting device is simple in structure and high in working efficiency.
