At this time, the movable contact ferry mechanism 6 operates, and according to the above description of the applicant, the movable contact transition groove 631 on the movable contact ferry push plate 63 corresponds to the right end of the movable contact sliding guide rail groove 221, the movable contact 40 enters one movable contact transition groove 631, and the movable contact ferry push plate moving action cylinder 62 of the movable contact ferry mechanism 6 operates in the reverse direction to displace the movable contact ferry push plate 63 in the reverse direction with respect to the displacement direction, so that the movable contact 40 located on the movable contact transition groove 631 corresponds to the movable contact sliding groove 3011 of the movable contact transition guide 301 and the push rod fitting groove 3031 in accordance with the correspondence between the movable contact transition groove 631 and the movable contact sliding groove 3011 and the push rod fitting groove 3031, that is, the movable contact 40 corresponds to the space between the movable contact sliding groove 3011 and the push rod fitting groove 3031. When the movable contact pushing mechanism 7 is operated, the movable contact pushing rod pushes the movable contact 40 into the movable contact accommodating cavity 1011 at the upper part of the bearing die top pin hole 101 of the welding bearing die 10, after the pushing is finished, the movable contact pushing rod drives the acting cylinder 72 to work reversely so as to return the movable contact pushing rod 74 (displace leftwards), and the movable contact ferry push plate moving acting cylinder 62 also works reversely so as to displace the movable contact ferry push plate 63 backwards to make the movable contact transition groove 631 correspond to the movable contact sliding guide rail groove 221 again to receive the movable contact 40.
In the above-mentioned action process, the movable contact spring piece vibrating plate 12 and the movable contact conveying guide rail vibrator 31 are also in an operating state, the movable contact spring piece 50 enters the movable contact spring piece guiding groove 321, and at this time, under the operation of the movable contact spring piece transferring mechanism 8, the movable contact spring piece 50 is transferred to the movable contact spring piece welding bearing platform 20 in a rising state, specifically: the movable contact spring piece transfer nozzle up-and-down displacement acting cylinder 84 operates to make the upper-and-lower displacement acting cylinder slider 841 move downward together with the movable contact spring piece transfer nozzle holder 85 and the movable contact spring piece transfer nozzle 86, and one movable contact spring piece 50 is sucked by the movable contact spring piece transfer nozzle 86 under the action of a negative pressure device such as a vacuum pump or the like connected with the movable contact spring piece transfer nozzle 86 through a pipeline, and then the movable contact spring piece transfer nozzle up-and-down displacement acting cylinder 84 operates in the reverse direction, and the movable contact spring piece transfer nozzle 86 moves upward. Then, the movable contact spring piece transfer suction nozzle lateral displacement acting cylinder 82 works to make the movable contact spring piece transfer suction nozzle lateral displacement acting cylinder slider 821 move backward, i.e. towards the movable contact spring piece welding bearing table 20, until the movable contact spring piece transfer suction nozzle 86 sucking the movable contact spring piece 50 is correspondingly above the movable contact spring piece accommodating cavity 201 of the movable contact spring piece welding bearing table 20. The movable contact spring piece transfer nozzle 86 is lowered to the extent that the movable contact spring piece 50 it has sucked is lowered into the cavity of the movable contact spring piece accommodation cavity 201 immediately after the movable contact spring piece transfer nozzle up-down displacement action cylinder 84 works in the reverse direction with respect to the aforementioned action direction. At this time, the movable contact spring piece transfer nozzle 86 is changed from the previous negative pressure to the positive pressure to release the movable contact spring piece 50 into the movable contact spring piece accommodation chamber 201. The moving contact spring piece transfer nozzle up-and-down displacement acting cylinder 84 moves up and the moving contact spring piece transfer nozzle lateral displacement acting cylinder 82 moves in the reverse direction with respect to the above, causes the moving contact spring piece transfer nozzle 86 to correspond again to the upper side of the moving contact spring piece guide groove 321, and repeats the above-described operation to suck the moving contact spring piece 50.
After the movable contact spring piece 50 is released into the movable contact spring piece accommodating cavity 201, the welding part (i.e., the aforementioned welding part) of the movable contact spring piece 50 just passes through the movable contact spring piece relief notch 2011 and corresponds to the upper part of the movable contact 40, i.e., the welding part of the movable contact spring piece 50 just covers the top of the welding bearing die 10 and corresponds to the movable contact 40 in the movable contact accommodating cavity 1011. At this time, the welding head vertical displacement driving mechanism 9 works, specifically: the welding head lifting cylinder 92 moves the welding head lifting cylinder 921 downward, the welding head lifting cylinder 921 pushes the welding head fixing base connection slider 93, the welding head fixing base 94 and the welding head 95 downward, the lower end of the welding head 95 is welded in a state of contacting with the welding part of the movable contact spring piece 50 (the welding machine 14 is in a working state), the movable contact 40 and the welding part (downward side) of the movable contact spring piece 50 are consolidated into a whole, and then the welding head 95 is moved upward and returned to a standby state under the reverse operation of the welding head lifting cylinder 92, that is, in a state of preparing for welding the welding part of the movable contact 40 and the movable contact spring piece 50 in the next process.
After the welding is completed, the movable contact spring piece welding plummer displacement mechanism 5 operates, the plummer up-down displacement action cylinder 55 operates to make the plummer up-down displacement action cylinder slide 551 move down to drive the movable contact spring piece welding plummer 20 to move down, then the plummer up-down displacement action cylinder 53 operates to drive the plummer up-down displacement action cylinder 55 and the movable contact spring piece welding plummer 20 to move forward (taking the position state of fig. 1 as an example) by the plummer up-down displacement action cylinder slide 531, and in this state, the movable contact spring piece 50 and the movable contact 40 which have previously completed the welding are in a half-suspended state on the welding plummer 10. At this time, under the operation of the thimble driving action cylinder 43 of the structural system of the movable contact welding mold carrying mechanism 4, the thimble 44 goes upward to push and push the movable contact 40 upward, so that the movable contact spring piece 50 together with the movable contact leaves the welding carrying mold 10 and falls to the discharge chute 60.
Since the above mechanisms are operated in a continuous and repetitive manner, the applicant does not describe the repetitive operation.
To sum up, the technical solution provided by the present invention remedies the defects in the prior art, successfully completes the invention task, and faithfully embodies the technical effects mentioned in the above technical effect column by the applicant.
