The down moving driving unit 233 includes a down moving driving cylinder 2331, a down moving rail block 2332 and a down moving base plate 2333; a down-moving driving cylinder 2331 and a down-moving guide rail slide block 2332 are fixed on the frame, and the output end of the down-moving driving cylinder 2331 is connected with a down-moving bottom plate 2333; the take-down base plate 2333 is connected to a slide in the take-down rail slide 2332 and the take-down base plate 2333 is connected to the first clamping member 234 and the second clamping member 235, respectively.
As shown in fig. 8, the card socket pushing assembly 231 includes a card socket loading block 2311, a card socket pushing cylinder 2312 and a card socket pushing block 2313; the output end of the clamping seat material pushing cylinder 2312 is connected with a clamping seat material pushing block 2313, and the clamping seat material pushing block 2313 is matched with the clamping seat; when the clamping seat material pushing cylinder 2312 is in an extending and contracting state, the clamping seat material pushing block 2313 is respectively connected with the output end of the clamping seat material loading block 2311 and the bottom end of the lower pressure head 2363.
The pin pressing mechanism 23 is in operation: 1) the clamping seat pushing cylinder 2312 acts to push the clamping seat loaded in the clamping seat pushing block 2313 out to a press-mounting station; 2) the clamping cylinder 2352 is contracted, the clamping roller 2354 is contacted with the top end of the clamping inclined plane 2353, and the top end of the first clamping head 2342 and the top end of the second clamping head 2355 move to the position below a single contact pin at the output end of the contact pin poking mechanism 22; 3) the downward movement driving cylinder 2331 moves to drive the first clamping head 2342 and the second clamping head 2355 to move upwards, and the single contact pin at the output end of the contact pin material poking mechanism 22 is clamped between the top end of the first clamping head 2342 and the top end of the second clamping head 2355; 4) the clamping cylinder 2352 extends out, the clamping roller 2354 is in contact with the tail end of the clamping inclined plane 2353, and the first clamping head 2342 and the second clamping head 2355 drive the contact pin to move to a press-fitting station; 5) the action of the pressing cylinder 2361 drives the pressing head 2363 to move downwards to press the single contact pin clamped by the first clamping head 2342 and the second clamping head 2355 into the corresponding hole position of the clamping seat, so that the pressing process is completed.
The pin pressing mechanism 23 solves the problem that when the pin and the cassette are pressed, a gas claw hand in the moving mechanism firstly clamps and moves the single pin from the upper part to the corresponding hole position of the cassette for positioning, and then the pin pressing mechanism acts to press the single pin into the corresponding hole position of the cassette; when the air claw hand grabs the contact pin from the upper part of the contact pin, the upper part of the contact pin can be shielded, and when the air claw hand grabs the contact pin to a corresponding hole position of the clamping seat to position the contact pin, the contact pin pressing mechanism can not press the contact pin from the upper part; therefore, after the air claw above the contact pin is released by the hand to move to the initial position, the contact pin can be pressed to the corresponding hole position of the clamping seat by the contact pin pressing mechanism; after the air claw hand returns to the initial position, the air claw hand does not have a fixing effect on the contact pin, and the contact pin is only subjected to a tiny limiting effect of the corresponding hole position when being moved to the clamping seat; when the contact pin pushing mechanism pushes down, the contact pin which is partially limited and not firm is stressed to shake when pushing down, so that the situation that the contact pin deviates relative to the hole position of the clamping seat occurs, and the problem of contact pin press mounting quality is reduced. The lower pressing component 232 is moved by setting; after the cassette pushing assembly 231 feeds the cassette to the press-fitting station, the clamping cylinder 2352 contracts, the clamping roller 2354 contacts with the top end of the clamping inclined plane 2353, and the top end of the first clamping head 2342 and the top end of the second clamping head 2355 move to be below a single contact pin at the output end of the contact pin pushing mechanism 22; the downward movement driving cylinder 2331 moves to drive the first clamping head 2342 and the second clamping head 2355 to move upwards, and the single contact pin at the output end of the contact pin material poking mechanism 22 is clamped between the top end of the first clamping head 2342 and the top end of the second clamping head 2355; the clamping cylinder 2352 extends out, the clamping roller 2354 is in contact with the tail end of the clamping inclined plane 2353, and the first clamping head 2342 and the second clamping head 2355 drive the contact pin to move to a press-fitting station; the action of the pressing cylinder 2361 drives the pressing head 2363 to move downwards to press the single contact pin clamped by the first clamping head 2342 and the second clamping head 2355 into the corresponding hole position of the clamping seat, so that the pressing process is completed. The first clamping head 2342 and the second clamping head 2355 clamp the side surface of the contact pin, so that the upper part of the contact pin is not shielded, and the lower pressing head 2363 is not influenced to press the contact pin downwards from the upper part; meanwhile, throughout the pressing down process, the first clamping head 2342 and the second clamping head 2355 are always in contact with the contact pin and elastically clamp the contact pin; that is, when the lower pressure head 2363 presses down the contact pin, the first clamping head 2342 and the second clamping head 2355 still fix the contact pin by elastic clamping; the condition that the initial position can not be fixed when pushing down the contact pin because stopping that the contact pin pushes down the mechanism and push down when having avoided the gas claw hand to press down the contact pin prevents that the contact pin from taking place the skew for the cassette hole site, has improved contact pin pressure equipment quality.
