Description

Technical Field

[0001] The present invention belongs to the technical field of diode processing and relates to a pin processing device for diode production. Background Art

[0002] With the rapid development of the electronics industry, as one of the basic electronic components, diodes play a crucial role in various electronic devices. The quality and performance of diodes directly affect the stability and reliability of the final products. In the production process of diodes, pin processing is a key step, which is directly related to the reliability of the connection between the diode and the circuit board and the electrical performance.

[0003] Currently, when processing the pins of diodes, it is necessary to bend the pins of the diodes. In the existing method of bending the pins of diodes, the bending process is achieved through the cooperation of a robotic arm and a forming die. During operation, the diode is first placed at the forming die, and then the punching die is driven by the robotic arm to squeeze the diode, thereby achieving the bending process of the diode pins. After the processing is completed, the original diode needs to be taken out, and then a new diode is replaced for processing. After each processing, the diode needs to be replaced, making it difficult to continuously process the diodes. The operation process is more cumbersome and the processing efficiency is relatively low. Summary of the Invention

Specific embodiments

[0029] The present invention will be further described below in conjunction with specific embodiments. It should also be noted that unless otherwise clearly specified and defined, terms such as: setting, installation, connection, and coupling should be understood in a broad sense.

For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0030] A pin processing device for diode production, as Figures 1-6 shown, includes a bottom plate 1, a frame 2, a turntable 3, a fixed plate 4, a fixed shaft 5, an extrusion ring 7, a driving mechanism, and a clamping mechanism. The top of the bottom plate 1 is connected to the frame 2. The turntables 3 are rotatably connected to both the front and rear sides of the frame 2. The upper middle part of the frame 2 is connected to a fixed shaft 5. Both the front and rear sides of the fixed shaft 5 are connected to fixed plates 4. The two fixed plates 4 are respectively located inside the two turntables 3. The outer circle of the fixed plate 4 is connected to an extrusion ring 7. A plurality of wire-releasing grooves are evenly spaced along the circumferential direction on the turntable 3. A driving mechanism is provided on the frame 2. The driving mechanism can drive the turntable 3 to rotate. A clamping mechanism for clamping the pins of the diode 100 is provided on the turntable 3.

[0031] As Figure 2 shown, the driving mechanism includes a drive motor 61, an internal gear ring 62, a rotating shaft 63, and a drive gear 64. The drive motor 61 is installed on the front side of the frame 2. The output shaft of the drive motor 61 is rotatably connected to the rotating shaft 63. The rotating shaft 63 is rotatably connected to the fixed shaft 5. Both the front and rear sides of the rotating shaft 63 are connected to drive gears 64. The middle parts of the mutually remote sides of the two turntables 3 are both connected to internal gear rings 62. The drive gear 64 meshes with the internal gear ring 62, so that when the drive motor 61 operates, the turntable 3 can be driven to rotate through the drive gear 64 and the internal gear ring 62.

[0032] AsFigure 2 and Figure 3 As shown in Figure 3 , the clamping mechanism includes a sliding frame 71, a clamping rod 72, a contact rod 73, a sliding block 74, an extension shaft 75, a first elastic member 76 and a second elastic member 77. A plurality of sliding frames 71 are slidably connected to the circumferential direction of the two turntables 3 at equal intervals on the side close to each other. A first elastic member 76 is connected between the sliding frame 71 and the turntable 3. The first elastic member 76 is a connecting spring. The number of the sliding frames 71 is the same as the number of the wire feeding grooves. The sliding frame 71 can slide in the radial direction of the turntable 3. Sliding blocks 74 are slidably connected to both sides of the sliding frame 71. A clamping rod 72 for clamping the pins is connected to the sliding block 74. A second elastic member 77 is connected between the sliding block 74 and the sliding frame 71. The second elastic member 77 is a compression spring. An inclined groove is formed in the sliding block 74. A contact rod 73 is slidably connected to the sliding frame 71. Convex shafts 78 are connected to both sides of the contact rod 73. The convex shafts 78 are located in the inclined groove. An extension shaft 75 is connected to the sliding frame 71. A slope is provided on the lower right side of the extrusion ring 7. The slope of the extrusion ring 7 is located at the contact rod 73, so that the contact rod 73 can move into contact with the slope of the extrusion ring 7 and be extruded by the slope of the extrusion ring 7.

[0033] As Figure 5 and Figure 6 As shown in Figure 5 and Figure 6 , an automatic bending mechanism is further included. The automatic bending mechanism includes an arc-shaped plate 81 and an arc-shaped guide rail 82. An arc-shaped plate 81 is connected to the upper right side of the fixed disk 4. An arc-shaped guide rail 82 is connected to the arc-shaped plate 81. The arc-shaped guide rail 82 is located at the moving track of the extension shaft 75, so that the extension shaft 75 can move into the arc-shaped guide rail 82. Subsequently, when the extension shaft 75 moves along the arc-shaped guide rail 82, it will be extruded by the arc-shaped guide rail 82, thereby driving the sliding frame 71 to move.

[0034] When the pins of the diode 100 need to be processed, this device can be used. During use, the driving motor 61 can be controlled to operate to drive the rotating shaft 63 to rotate. When the rotating shaft 63 rotates, it can drive the internal gear ring 62 to rotate. When the internal gear ring 62 rotates, it can drive the turntable 3 to rotate. When the turntable 3 rotates, it can drive the sliding frame 71 and the contact rod 73 to move. When the contact rod 73 moves, it can contact the inclined surface on the lower side of the extrusion ring 7. Subsequently, 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, thereby extruding the two sliding blocks 74 away from each other. The two elastic members II 77 are compressed. The two sliding blocks 74 moving away from each other can drive the two clamping rods 72 to move away from each other. Subsequently, the diode 100 can be placed on the two turntables 3, and the pins on both sides of the diode 100 are respectively stuck at the wire-releasing grooves of the two turntables 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 turntable 3 continues to rotate to drive the sliding frame 71 and the contact rod 73 to rotate. When the contact rod 73 disengages from the extrusion ring 7, under the action of the elastic member II 77, the sliding block 74 and the clamping rod 72 are reset. The reset of the clamping rod 72 can clamp the pins of the diode 100. Subsequently, when the turntable 3 continues to rotate, it can 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. Subsequently, the extension shaft 75 will be extruded by the arc-shaped guide rail 82, so that the extension shaft 75 moves into the turntable 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 hold the pins of the diode 100 and move, thereby bending the pins. In this way, this device can be used to process the pins of the diode 100, and during the processing, the pins of the diode 100 can be processed continuously, with higher processing efficiency and more convenient operation.

[0035] As Figure 7 and Figure 8 shown, it further includes a blanking mechanism. The blanking mechanism includes a connecting frame 91, a feeding frame 92 and a cover plate 93. The left parts of the front and rear sides of the top of the frame 2 are both connected with a connecting frame 91. The top of the connecting frame 91 is connected with a feeding frame 92. The right side of the feeding frame 92 is connected with a cover plate 93.

[0036] When processing the pins of the diode 100, the addition work of the diode 100 needs to be carried out. At this time, the diodes 100 can be placed side by side in the feeding frame 92. When the gap between the two turntables 3 rotates to align with the lower part of the feeding frame 92, under the action of gravity, the diodes 100 fall. The falling of the diodes 100 will cause the pins on both sides of them to move to the wire-releasing grooves of the turntables 3, so that the automatic addition work of placing the diodes 100 can be realized, and the operation is more convenient.

[0037] As Figure 9 and Figure 10 shown, it further includes a cutting mechanism, and the cutting mechanism includes an external gear ring 101, a spline shaft 102, a sliding frame 103, a transmission gear 104 and a cutting wheel 105. External gear rings 101 are connected to the mutually remote sides of the two turntables 3. A spline shaft 102 is rotatably connected to the upper part of the connecting frame 91. A transmission gear 104 is connected to the inner side of the spline 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. A cutting wheel 105 is slidably connected to the spline shaft 102. Two sliding frames 103 are slidably connected to the right side of the cover plate 93. A knife groove is provided at the bottom of the sliding frame 103. The upper part of the cutting wheel 105 is located in the knife groove.

[0038] When the diodes 100 are added to the two sides of the turntables 3, the leads at both ends of the diodes 100 are too long and need to be trimmed. When the turntables 3 rotate to transfer the diodes 100, the external gear ring 101 and the transmission gear 104 can also drive the spline shaft 102 to rotate. When the spline shaft 102 rotates, it can drive the cutting wheel 105 to rotate. When the lead of the diode 100 rotates to contact the cutting wheel 105, the cutting wheel 105 can cut off the too long part of the lead. In this way, the too long part of the lead can be automatically trimmed. During the actual operation, the sliding frame 103 can be pulled back and forth to drive the cutting wheel 105 to move, so as to adjust the position of the cutting wheel 105.

[0039] As Figure 11 shown, it further includes an alignment mechanism, and the alignment mechanism includes a bracket 111 and a guide plate 112. The bracket 111 is connected to the lower right part of the cover plate 93. Guide plates 112 are connected to 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 on the moving track of the diode 100.

[0040] When the diode 100 falls between the two turntables 3, its position may deviate. When the turntables 3 drive the diode 100 to rotate, both sides of the diode 100 will respectively contact the two guide plates 112. By squeezing the front and rear sides of the diode 100 through the guide plates 112, the diode 100 is positioned to prevent the position of the diode 100 at the turntable 3 from shifting, ensuring the accuracy of the lead trimming work.

[0041] As Figure 12As shown in the figure, it further includes a bidirectional screw 12. The lower right side of the cover plate 93 is rotatably connected to the bidirectional screw 12. The two sides of the bidirectional screw 12 are respectively in threaded cooperation with two sliding frames 103, so that the rotation of the bidirectional screw 12 can drive the two sliding frames 103 to approach or move away from each other through the thread. When it is necessary to adjust the position of the sliding frame 103, the bidirectional screw 12 can be rotated to drive the two sliding frames 103 to approach or move away from each other through the thread, so as to adjust the position of the sliding frame 103, enabling the two sliding frames 103 to be adjusted synchronously, which is more convenient during adjustment.

[0042] The above embodiments are only the preferred embodiments of the present invention and are not used to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the content described in the claims of the present invention should be included within the scope of the claims of the present invention.
