[0030] A pin handling device for diode manufacturing, such as Figures 1-6 As shown, the device includes a base plate 1, a frame 2, a turntable 3, a fixed plate 4, a fixed shaft 5, a pressing ring 7, a drive mechanism, and a clamping mechanism.

[0031] like Figure 2 As shown, the drive mechanism includes a drive motor 61, an internal gear ring 62, a rotating shaft 63, and a drive gear 64.

[0032] likeFigure 2 And Figure 3 As shown in FIG. 1, the clamping mechanism comprises sliding frames 71, clamping rods 72, contact rods 73, sliding blocks 74, extension shafts 75, elastic members one 76 and elastic members two 77. Multiple sliding frames 71 are uniformly and circumferentially spaced apart and connected to one side of each of the two side turntables 3. The sliding frames 71 are connected with the turntables 3 via elastic members one 76, which are connecting springs.

The inclined surface of the extrusion ring 7 is located at the contact rod 73, so that the movement of the contact rod 73 can be in contact with the inclined surface of the extrusion ring 7, thereby being extruded by the inclined surface of the extrusion ring 7.
[0033] As shown in FIG. 1, the clamping mechanism comprises sliding frames 71, clamping rods 72, contact rods 73, sliding blocks 74, extension shafts 75, elastic members one 76 and elastic members two 77. Multiple sliding frames 71 are uniformly and circumferentially spaced apart and connected to one side of each of the two side turntables 3. The sliding frames 71 are connected with the turntables 3 via elastic members one 76, which are connecting springs. The number of the sliding frames 71 is consistent with the number of the pay-off grooves. The sliding frames 71 can slide along the radial direction of the turntable 3. The sliding blocks 74 are connected to both sides of the sliding frames 71. The sliding blocks 74 are connected with the clamping rods 72 for clamping the pins. The sliding blocks 74 are connected with the sliding frames 71 via elastic members two 77, which are compression springs. An inclined groove is formed in the sliding block 74. The contact rods 73 are connected to the sliding frames 71. The contact rods 73 are connected with convex shafts 78 on both sides. The convex shafts 78 are located in the inclined groove. The extension shafts 75 are connected to the sliding frames 71. An inclined surface is arranged on the right lower part of the extrusion ring 7. The inclined surface of the extrusion ring 7 is located at the contact rod 73, so that the movement of the contact rod 73 can be in contact with the inclined surface of the extrusion ring 7, thereby being extruded by the inclined surface of the extrusion ring 7. Figure 5 Figure 6 As shown in FIG. 1, the clamping mechanism comprises sliding frames 71, clamping rods 72, contact rods 73, sliding blocks 74, extension shafts 75, elastic members one 76 and elastic members two 77. Multiple sliding frames 71 are uniformly and circumferentially spaced apart and connected to one side of each of the two side turntables 3. The sliding frames 71 are connected with the turntables 3 via elastic members one 76, which are connecting springs. The number of the sliding frames 71 is consistent with the number of the pay-off grooves. The sliding frames 71 can slide along the radial direction of the turntable 3. The sliding blocks 74 are connected to both sides of the sliding frames 71. The sliding blocks 74 are connected with the clamping rods 72 for clamping the pins. The sliding blocks 74 are connected with the sliding frames 71 via elastic members two 77, which are compression springs. An inclined groove is formed in the sliding block 74. The contact rods 73 are connected to the sliding frames 71. The contact rods 73 are connected with convex shafts 78 on both sides. The convex shafts 78 are located in the inclined groove. The extension shafts 75 are connected to the sliding frames 71. An inclined surface is arranged on the right lower part of the extrusion ring 7. The inclined surface of the extrusion ring 7 is located at the contact rod 73, so that the movement of the contact rod 73 can be in contact with the inclined surface of the extrusion ring 7, thereby being extruded by the inclined surface of the extrusion ring 7.
[0034] When the pins of the diode 100 need to be processed, the device can be used. In use, the driving motor 61 can be controlled to drive the rotating shaft 63 to rotate. When the rotating shaft 63 rotates, the inner gear ring 62 can be driven to rotate. When the inner gear ring 62 rotates, the rotating disc 3 can be driven to rotate. When the rotating disc 3 rotates, the sliding frame 71 and the contact rod 73 can be moved. When the contact rod 73 moves, it can contact the inclined surface on the lower side of the extrusion ring 7. Then the contact rod 73 is extruded by the inclined surface of the extrusion ring 7, so that the contact rod 73 moves inward. When the contact rod 73 moves, it can drive the convex shaft 78 to move. When the convex shaft 78 moves, it can extrude the inclined groove, so as to extrude the two sliding blocks 74 away from each other. The two elastic members two 77 are compressed. The two sliding blocks 74 away from each other can drive the two clamping rods 72 away from each other. Then the diode 100 can be placed on the two rotating discs 3, and the pins on both sides of the diode 100 are clamped in the wire slot of the rotating disc 3 on both sides. At this time, the pins of the diode 100 are located between the two clamping rods 72. At this time, the rotating disc 3 continues to rotate to drive the sliding frame 71 and the contact rod 73 to rotate. When the contact rod 73 is separated from the extrusion ring 7, the sliding block 74 and the clamping rod 72 are reset under the action of the elastic member two 77. The clamping rod 72 resets to clamp the pins of the diode 100. Then the rotating disc 3 continues to rotate to drive the sliding frame 71 and the extension shaft 75 to continue to move. When the extension shaft 75 moves, it can enter the arc-shaped guide rail 82. Then the extension shaft 75 is extruded by the arc-shaped guide rail 82, so that the extension shaft 75 moves towards the rotating disc 3. When the extension shaft 75 moves, it can drive the sliding frame 71 to move. When the sliding frame 71 moves, it can drive the clamping rod 72 to move. When the clamping rod 72 moves, it can move the pins of the diode 100 to bend the pins. Thus, the device can be used to process the pins of the diode 100, and the diode 100 pins can be processed continuously during processing, which is more efficient and convenient to operate.
[0035] As shown in Figure 7 and Figure 8 It also includes a blanking mechanism. The blanking mechanism includes a connecting frame 91, a feeding frame 92 and a cover plate 93. The left part of the top of the rack 2 is connected with the connecting frame 91. The top of the connecting frame 91 is connected with the feeding frame 92. The right side of the feeding frame 92 is connected with the cover plate 93.
[0036] When the pins of the diode 100 are processed, the diode 100 needs to be added. At this time, the diodes 100 can be placed side by side in the feeding frame 92. When the gap between the two rotating discs 3 is aligned below the feeding frame 92, the diodes 100 fall under the action of gravity. The falling of the diodes 100 can move the pins on both sides to the wire slot of the rotating disc 3, so as to realize the automatic adding work of placing the diodes 100. It is more convenient to operate.
[0037] like Figure 9 and Figure 10 As shown, it also includes a cutting mechanism, which includes an external gear ring 101, a splined shaft 102, a sliding frame 103, a transmission gear 104, and a cutting wheel 105. The two turntables 3 are connected to the external gear ring 101 on opposite sides. The splined shaft 102 is rotatably connected to the upper part of the connecting frame 91. The transmission gear 104 is connected to the inner side of the splined shaft 102. The transmission gear 104 meshes with the external gear ring 101 so that the rotation of the external gear ring 101 can drive the transmission gear 104 to rotate. The cutting wheel 105 is slidably connected to the splined shaft 102. Two sliding frames 103 are slidably connected to the right side of the cover plate 93. The bottom of the sliding frame 103 is provided with a knife groove, and the upper part of the cutting wheel 105 is located in the knife groove.
[0038] When diode 100 is added to the two rotating disks 3, the leads at both ends of diode 100 are too long and need to be trimmed. When the rotating disk 3 rotates to transfer diode 100, it can also drive spline shaft 102 to rotate through external gear ring 101 and transmission gear 104. When spline shaft 102 rotates, it can drive cutting wheel 105 to rotate. When the lead of diode 100 rotates to contact cutting wheel 105, cutting wheel 105 can cut off the excessively long part of the lead. In this way, the excessively long part of the lead can be automatically trimmed. In actual operation, the sliding frame 103 can be pulled back and forth to drive cutting wheel 105 to move, thereby adjusting the position of cutting wheel 105.
[0039] like Figure 11 As shown, it also includes an alignment mechanism, which includes a bracket 111 and a guide plate 112. The bracket 111 is connected to the lower right side of the cover plate 93. The guide plate 112 is connected to both the front and rear sides of the lower part of the bracket 111. The left side of the guide plate 112 is inclined. After the diode 100 is placed, the guide plate 112 is located at the movement trajectory of the diode 100.
[0040] When diode 100 falls between the two turntables 3, its position may be off. When the turntable 3 drives the diode 100 to rotate, both sides of the diode 100 will contact the two guide plates 112 respectively. The guide plates 112 press the front and rear sides of the diode 100 to position the diode 100, so as to avoid the diode 100 from shifting its position at the turntable 3 and ensure the accuracy of the pin trimming work.
[0041] like Figure 12The illustrated, further include a two-way screw 12, the cover plate 93 right lower part of the rotating connection with two-way screw 12, two-way screw 12 both sides are respectively with two sliding frame 103 screw thread cooperation, to make two-way screw 12 rotation can be driven by screw thread two sliding frame 103 each other close or each other away, in need to adjust the position of sliding frame 103, can rotate two-way screw 12 by screw thread driven two sliding frame 103 each other close or each other away, to adjust the position of sliding frame 103, so that two sliding frame 103 can be adjusted synchronously, more convenient when adjusting.
