[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0030] Among them, the first mechanical arm 1 is used to drive the first fixture 3 to switch between the material picking station and the transfer station; the second mechanical arm 2 is used to drive the second fixture 4 to switch between the transfer station and the unloading station; the first fixture 3 and the second fixture 4 both have multiple PIN needle installation cavities 9, and the first fixture 3 and the second fixture 4 are both installed with multiple push pin rods 12 corresponding to the PIN needle installation cavities 9 one by one, and the multiple push pin rods 12 are simultaneously reciprocated in the PIN needle installation cavity 9 to push out multiple PIN needles at the same time and restore the multiple PIN needle installation cavities 9 to a state that can accommodate PIN needles at the same time; the first fixture 3 and the second fixture 4 are also both installed with a driving device for driving the push pin rod 12 to move back and forth, and the driving device includes a driver 10 and a push pin plate 11, and the push pin plate 11 is fixed between the output end of the driver 10 and the push pin rod 12, and the driver 10 is preferably a cylinder; the driver 10 can also be selected as a power machine that directly outputs linear reciprocating motion, such as an electric push rod and a hydraulic cylinder;

[0046] Track groove 2 includes transition groove 4 617, drive groove 4 618 and drive groove 5 619 which are sequentially arranged along the rotation direction of turntable 61 and connected end to end. Transition groove 4 617 is an arc-shaped groove concentric with turntable 61. The intersection of drive groove 4 618 and drive groove 5 619 is located outside the circle where transition groove 4 617 is located.

[0047] The intersection of the driving groove 4 618 and the transition groove 4 617 and the intersection of the driving groove 5 619 and the transition groove 4 617 are both located in the fan-shaped area corresponding to the arc where the transition groove 3 615 is located.

[0048] During the rotation of the turntable 61, the transition groove 1 611, the drive groove 1 612, the transition groove 2 613, the drive groove 2 614, the transition groove 3 615 and the drive groove 3 616 are matched with the transmission rod 1 64 in sequence and reciprocate periodically, so that the transmission rod 1 64 is stationary for the first time relative to the center of the turntable 61, moves away radially for the first time, stationary for the second time, moves away radially for the second time, stationary for the third time, moves close to the first time and resets and reciprocates periodically;

[0049] The transition groove four 617, the driving groove four 618 and the driving groove five 619 cooperate with the transmission rod two 65 in sequence and reciprocate periodically, so that the transmission rod two 65 is stationary for the fourth time relative to the center of the turntable 61, moves away radially for the third time, moves closer to reset for the second time and reciprocates periodically.

[0050] In the first static stage, a needle loading hole 521 on the slider 52 is docked with the needle guide hole 512, so that a PIN needle is loaded into the needle loading hole 521 through the needle guide hole 512; in the first radial movement away stage, the slider 52 slides to move the needle loading hole 521 equipped with the PIN needle toward the guide hole 513, and moves the other needle loading hole 521 to dock with the needle guide hole 512; in the second static stage, another PIN needle is loaded into the needle loading hole 521 through the needle guide hole 512; in the second radial away stage, the slider 52 slides further to dock the two needle loading holes 521 equipped with the PIN needles with the two guide holes 513 respectively; in the third static stage, the two needle loading holes 521 remain docked with the two guide holes 513; in the first radial movement approaching and resetting stage, the slider 52 slides in the slide groove 511 and restores its own position to the position of the slider 52 in the slide groove 511 during the first static stage.

[0051] From the beginning of the first static stage to the end of the second radially away stage, the transition groove four 617 rotates and maintains contact with the transmission rod two 65, keeping the transmission rod two 65 stationary relative to the center of the turntable 61; at the beginning of the third static stage or a period of time after the beginning, the transmission rod two 65 is converted from being located in the transition groove four 617 to being located in the drive groove four 618 and radially away from the center of the turntable 61, so as to drive the gear set two 63 to rotate, push the transmission frame 66 and the drive column 54 toward the guide seat 51, and push the push rod 53 into the guide hole 513 and the pin hole 521, so that the PIN needle moves out of the guide seat 51 from the other opening of the guide hole 513, and then, the transmission rod two 65 is converted from being located in the drive groove four 618 to being located in the drive groove five 619 and radially close to reset, and the push rod 53 is moved out of the pin hole 521 and the guide hole 513. At the end of the third static stage or before the end, the transmission rod two 65 returns to the transition groove four 617.

[0052] During the first radial movement and reset phase, the transmission rod 2 65 remains in the transition groove 4 617.

[0053] By setting the driving mechanism 6, the reciprocating movement of the slider 52 and the push rod 53 is driven by the rotation of the turntable 61, so that the PIN pins are arranged in groups of two and are simultaneously loaded into the two PIN pin installation cavities 9 in the first fixture 3 after arrangement, thereby realizing the rapid loading of the PIN pins on the first fixture 3; and in this process, the upper limit of the speed adjustment of the turntable 61 is high and the speed adjustment is convenient, so that the installation speed of the PIN pins on the first fixture 3 can be quickly adaptively adjusted according to the speed at which the second robot arm 2 moves the second fixture 4, which is more practical, reduces the waiting time after the second fixture 4 comes out of the mold, and realizes the improvement of the PIN pin installation efficiency.

[0054] It should be noted that, for those skilled in the art, the driving mechanism 6 can also be composed of multiple linear driving units (such as a cylinder, a hydraulic cylinder, and an electric push rod, etc.). The slider 52 and the push rod 53 are driven by different linear driving units.

[0055] It should be noted that, for those skilled in the art, a discharge mechanism 5 and a drive mechanism 6 for installing one PIN needle or three or more PIN needles on the first fixture 3 at a time can be designed with reference to the embodiments of the present invention.
