Description

Technical Field

[0001] The utility model relates to a diode rapid assembly structure, belonging to the technical field of diode processing equipment. Background Art

[0002] The diode processing process involves a diode lead shearing process, which involves using a cutting tool to shear the diode leads to a specified height. Existing diode shearing equipment installs shearing tools on both sides of a feed track slot. The diodes are transported linearly along the feed track slot to the shearing tool position, and only one diode can be transported to the tool position at a time, which severely restricts the efficiency of diode lead shearing. Furthermore, the feed track slot is relatively long, and the diode socket is completely enclosed within the slot. Feeding relies on vibration and gravity, making the diode prone to material jamming and socket wear. Furthermore, the diode leads should remain vertical on the socket, but in actual production, some diode leads have curved or tilted structures. Summary of the Invention

[0003] The purpose of this utility model is to provide a fast diode assembly structure. The utility model adopts a 1-out-2 structural design, feeding two diodes at a time, which doubles the diode assembly efficiency. The conveyor track uses a concave groove belt to prevent material jamming and tube socket wear. In addition, the diode leads can be straightened during the diode assembly process.

[0012] 2. The transmission structure uses a transmission belt plus two bars to form a concave groove belt transmission structure. Driven by the motor, the transmission belt can continuously transport the diodes forward, eliminating the occurrence of material jams and tube seat wear.

DETAILED DESCRIPTION

[0019] The present invention will be further described below with reference to the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0020] The embodiment of the utility model: a diode quick assembly structure, such as Figure 1-3 As shown, it includes a feeding tray 1, and a plurality of notches are distributed in a ring array on the edge of the feeding tray 1, and an assembly block 2 is fixed at each notch, and two assembly stations 3 are arranged at intervals on the assembly block 2, and a U-shaped distribution groove 4 is fixed on the outside of the feeding tray 1. The U-shaped distribution groove 4 includes two vertical grooves and a horizontal groove, and a distribution cylinder 5 is arranged on the outside of the U-shaped distribution groove 4, and the push rod of the distribution cylinder 5 is fixedly connected to the vertically arranged push plate 6 located in the horizontal groove, and the push rod of the distribution cylinder 5 is parallel to the horizontal groove of the U-shaped distribution groove 4, and the distribution cylinder 5 is located above the horizontal groove, and a conveyor belt 7 is provided at the left end in the middle of the horizontal groove, and baffles 8 are provided on both sides of the conveyor belt 7. The end of the conveyor belt 7 is connected with the horizontal groove, and assembly cylinders 9 are fixed on the sides of the baffles 8 on both sides of the tail of the conveyor belt 7. The push rod of the assembly cylinder 9 is fixedly connected to the assembly slider 10, and the two assembly sliders 10 are arranged opposite the two vertical grooves. The head end of the conveyor belt 7 is connected to the conveying device 11 of the vibrating feeding tray.

[0021] The diodes conveyed by the vibrating disk enter the conveyor belt 7 from the conveyor device 11 and are transported forward along the conveyor belt 7. From the end of the conveyor belt 7, they enter the horizontal groove of the U-shaped distribution groove 4. Then, the push plate 6 is pushed forward by the distribution cylinder 5, so that the diodes in the horizontal groove enter the vertical groove in front. At the same time, the diodes in the conveyor belt 7 continue to be transported forward and enter the horizontal groove. When the push plate 6 is retracted backward under the action of the distribution cylinder 5, the diodes in the horizontal groove are pushed into the vertical groove at the rear. When there are diodes in both vertical grooves, the two assembly cylinders 9 are actuated, so that the assembly slide 10 is pushed forward into the vertical groove. Under the push of the assembly slide 10, the two diodes in the vertical groove are pushed into the two assembly stations 3 of the assembly block 2, so that two diodes are assembled at the same time. Then the feed tray 1 rotates and the assembled diodes are sent to the shearing station for lead shearing. Then the assembly cylinder 9 drives the assembly slide 10 to reset, and the distribution cylinder 5 is actuated again.

[0022] The conveyor device 11 is arranged outside the conveyor belt 7, and the two are arranged parallel to each other. The end of the conveyor device 11 is connected to a T-shaped guide groove 12. The vertical groove of the T-shaped guide groove 12 is connected to the end of the conveyor device 11, and one end of the horizontal groove is connected to the inlet on the side of the conveyor belt 7. The other end of the horizontal groove is provided with a guide block 13, which is connected to the push rod of the guide cylinder 14. The diode enters the vertical groove of the T-shaped guide groove 12 from the conveyor device 11 and moves to the middle of the horizontal groove under the mutual compression. Then, the guide block 13 pushes out and pushes the diode from the T-shaped guide groove 12 into the conveyor belt 7.

[0023] A vertical stopper 15 is provided at the entrance on the side of the conveyor belt 7. The bottom of the vertical stopper 15 is connected to a driving cylinder. When the guide block 13 is pushed forward, the vertical stopper 15 drops downward, and the diode is pushed from the T-shaped guide groove 12 into the conveyor belt 7 through the guide block 13.

[0024] A limit block 16 is connected between the two baffles 8 on the left side of the inlet of the conveyor belt 7. The limit block 16 can prevent the diodes entering the conveyor belt 7 from the T-shaped guide groove 12 from falling backward, ensuring that the diodes are always in a vertical state.

[0025] A lead straightening mechanism is located above the bars 8 in front of the assembly cylinder 9. This mechanism includes a clamping block 17 and a straightening block 18, each mounted above the two bars 8. The back of the clamping block 17 is fixedly connected to the push rod of a clamping cylinder 19, while the straightening block 18 is fixedly connected to the push rod of a straightening cylinder 20. The push rod of the clamping cylinder 19 is perpendicular to the conveying direction of the conveyor belt 7, while the push rod of the straightening cylinder 20 is parallel to the conveying direction of the conveyor belt 7. During diode lead straightening, the clamping block 17 is first pushed forward by the clamping cylinder 19, while the straightening block 18 remains stationary. The clamping block 17 and the straightening block 18 then operate to compress the leads. The straightening cylinder 20 then actuates, pushing the straightening block 18 along the length of the conveyor belt 7. The rubbing action of the clamping block 17 and the straightening block 18 straightens the diode leads. The clamping block 17 then retracts, and the straightening block 18 returns to its original position.

[0026] A distribution stopper 21 is provided between the horizontal groove of the U-shaped distribution groove 4 and the feed tray 1. The distribution stopper 21 is provided to limit the horizontal groove and prevent the diodes in the horizontal groove from moving forward and out of the horizontal groove position. Side blocks 22 are provided on the outside of the two vertical grooves of the U-shaped distribution groove 4 to ensure that when the push plate 6 moves back and forth to push the diodes, the diodes are always located in the vertical grooves of the U-shaped distribution groove 4 to prevent them from falling out of the vertical grooves.
