At this time, the pulling adjustment portion no longer acts on the supporting shaft 550. Under the action of the elastic pulling component 200, the two supporting strips 510 approach each other and the side portions of the chip body 300 rest against the retaining edge portion 520, thereby achieving automatic positioning and clamping.

[0033] In one embodiment, Figure 1-Figure 6 As shown, the pulling adjustment part includes an outer pull rod 590 and an outer pull base 700, one end of the outer pull rod 590 is fixedly connected to the end of the supporting shaft 550, and the other end of the outer pull rod 590 is in a state of being flush with the cross bar part 530; the outer pull base 700 is fixed on the vertical guide frame 110 and the outer pull base 700 is provided with an outer pull guide groove 710 with the top arched toward the side where the movable support frame 540 is located, and the end of the outer pull rod 590 away from the supporting shaft 550 can move along the outer pull guide groove 710; in an embodiment of the present invention, when the supporting shaft 550 moves downward and the switching guide rod part 541 moves downward from the notch at the end connecting groove 650, the end of the outer pull rod 590 away from the supporting shaft 550 slides from the top of the outer pull guide groove 710 into the inner part of the outer pull guide groove 710, and under the guidance of the outer pull guide groove 710, the outer pull rod 590 pulls the supporting shaft 550 to move toward the side away from the supporting slat 510.

[0034] In one embodiment, Figure 1-Figure 6As shown, the upper pressing member 560 includes a main rod 561, a lower pressing block 562 and a tail plate portion 563. The middle portion of the main rod 561 is rotatably connected to the cross rod portion 530.

The release blocking rod portion 570 includes a sleeve portion 571 and two side extension blocking rods 572, the sleeve portion 571 is rotatably connected to the movable support frame 540 and the support shaft 550 slides through the sleeve portion 571, the two side extension blocking rods 572 are symmetrically arranged on both sides of the sleeve portion 571 and one end of the side extension blocking rod 572 is fixedly connected to the outer wall of the sleeve portion 571; in the embodiment of the present invention, when the support shaft 550 is pulled away from the support strip under the action of the pull adjustment portion, When one side of the support 510 moves, the supporting strip 510 and the plurality of upper pressing members 560 all move toward the movable support frame 540, and the tail plate portion 563 gradually contacts the side extension blocking rod 572. As the tail plate portion 563 moves and the side extension blocking rod 572 acts on the tail plate portion 563, the tail plate portion 563 is compressed and the main rod 561 rotates around the cross bar portion 530, so that the lower pressing block 562 gradually rotates to the upper side of the cross bar portion 530, so that the lower pressing block 562 does not block the core The side of the chip body 300 is placed on the supporting strip 510; when the two supporting strips 510 move toward each other under the traction of the elastic pulling component 200, the side extension barrier 572 no longer pushes the tail plate portion 563. Under the elastic force of the downward pressure spring portion 565, the tail plate portion 563 drives the main rod 561 to rotate, and the downward pressure block 562 rotates to the upper side of the supporting strip 510 and presses the side of the chip body 300, thereby facilitating the placement and positioning of the chip body 300.

Therefore, when the chip body 300 and the supporting strip 510 flip 180 degrees, the welding device welds the chip body 300 and generates downward pressure. The side extending baffle rod 572 and the side extending baffle rod 572 prevent the lower pressure block 562 from rotating, thereby ensuring the stability of the chip body 300 during welding. In addition, the setting of the rotating sleeve 573 can make the side extending baffle rod 572 contact with the tail plate portion 563 and the outer extending baffle plate 564 in a rolling manner, thereby reducing friction during relative movement.
