[0026] In addition, the elastic member 123 may be an elastic element such as an elastic plastic strip, an elastic metal strip, a compression spring or a torsion spring, which is not limited here.

[0027] It is understandable that, referring to Figure 1 and Figure 2The feeding mechanism 200 further includes a blanking plate 230, which is fixedly connected to the frame 100. The blanking plate 230 and the turntable 120 are arranged adjacent to each other, and the blanking plate 230 is used to guide the diode to escape from the opening slot 121. The blanking plate 230 is fixedly connected to the frame 100. By setting the blanking plate 230 and the turntable 120 to be arranged adjacent to each other, when the turntable 120 drives the diode to rotate, the pin of the diode can abut against the blanking plate 230.

The first slider 350 is slidably connected to the mounting frame 310, and the second tool 330 is fixedly connected to the first slider 350. The first slider 350 is provided with a first guide groove 351. The first eccentric shaft 340 is rotatably connected to the frame 100, and the first eccentric shaft 340 is located in the first guide groove 351. By driving the first eccentric shaft 340 to rotate, the first eccentric shaft 340 can drive the first slider 350 to slide on the mounting frame 310, so that the second tool 330 can be driven to reciprocate in a direction close to or away from the first tool 320, so that the first tool 320 and the second tool 330 can cooperate to continuously cut the pins of the diode, thereby improving the trimming efficiency of the diode pins.

The wear plate 311 is fixedly connected to the mounting frame 310, so that the wear plate 311 is located between the mounting frame 310 and the first slider 350. By providing the wear plate 311, the first slider 350 can be prevented from sliding directly on the mounting frame 310, thereby reducing the wear of the mounting frame 310 and the first slider 350 and extending the service life.

[0033] In addition, by providing a plurality of liquid storage tanks 312 on the wear-resistant plate 311, the contact area between the first slider 350 and the wear-resistant plate 311 can be reduced, thereby reducing the movement resistance of the first slider 350 on the wear-resistant plate 311.

The waste trough 360 is fixedly connected to the mounting frame 310, and is located between the first cutter 320 and the second cutter 330, so that when the first cutter 320 and the second cutter 330 cooperate to cut the pins of the diode, the waste of the cut pins can fall into the waste trough 360. By setting the waste trough 360 to be arranged at an angle, the waste can be guided to be smoothly output along the waste trough 360, and the waste can be avoided from accumulating, so that the cutting of the diode pins can be facilitated, and the cutting efficiency and quality can be improved.

[0035] Specifically, the waste trough 360 includes a bottom wall and two side walls, and the two side walls are respectively arranged on both sides of the base 211. A notch is opened on the side wall close to the first cutter 320, and the pins of the diode can extend into the notch. After the first cutter 320 and the second cutter 330 cooperate to cut the pins of the diode, the pin waste can accurately fall into the waste trough 360, so that the waste can be guided through the waste trough 360 for smooth output, thereby improving the convenience of use.

By driving the screw rod 371 to rotate, the screw rod 371 can drive the mounting frame 310 to slide on the adjusting seat 370, so that the cutting position of the diode pin can be adjusted, thereby improving the flexibility of the cutting mechanism 300.

[0037] It should be noted that the adjustment seat 370 is provided with an adjustment groove in the horizontal direction, and the mounting frame 310 is slidably connected to the adjustment groove. The mounting frame 310 can be driven to slide in the adjustment groove through the screw 371 to adjust the position of the mounting frame 310 on the adjustment seat 370, so that the positions of the first tool 320 and the second tool 330 can be flexibly adjusted, which is convenient for adjusting the cutting position of the diode pin and improving the flexibility of use.

[0038] It is understandable that, referring to Figure 2 and Fig.10The bending mechanism 400 further includes a second eccentric shaft 440, which is rotatably connected to the frame 100, a second top block 430 is fixedly connected to a second slider 450, the second slider 450 is slidably connected to the connecting frame 410, and the second slider 450 is provided with a second guide groove 451, in which the second eccentric shaft 440 is located.

The diodes are placed in the first grooves 216, and the second support plate 213 is driven by a driving member to move along the inclined direction of the connecting groove 215, so that the second groove 217 can move obliquely upward, so that the diodes can be transferred from the first groove 216 to the second groove 217, and then the driving member drives the second support plate 213 to reset, so that the diodes can be transferred from the second groove 217 to another first groove 216, so that the diodes can be transported one by one through the cooperation of the plurality of first grooves 216 and the plurality of second grooves 217, so as to realize automatic loading of the diodes and improve production efficiency.

[0040] It should be noted that the diode is placed in the first groove 216, and the second support plate 213 is driven by the driving member to move obliquely upward so that the second groove 217 can support the diode from the first groove 216, and then the driving member drives the second support plate 213 to reset, so that the diode can fall from the second groove 217 into the previous first groove 216, and the above actions are repeated, so that the diode can be conveyed forward one by one through the cooperative drive of multiple first grooves 216 and multiple second grooves 217, thereby realizing automatic loading of the diode and improving loading efficiency.
