DETAILED DESCRIPTION

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a diode pin forming machine, including a base 1 and two inner clamping plates 4. One end of the inner clamping plate 4 is fixedly connected to a lifting seat 3. A sliding seat 16 is provided between the two inner clamping plates 4. Two transmission rods 7 are rotatably connected to the inner sidewalls of the inner clamping plates 4. A linkage rod 8 is rotatably connected between the two transmission rods 7. One end of the transmission rod 7 is fixedly connected to a gear 17. Both ends of the sliding seat 16 are provided with teeth. A transmission rod 10 is rotatably connected to the inner sidewalls of the inner clamping plates 4. One end of the transmission rod 10 is fixedly connected to a gear 15. The gear 15 meshes with one end of the sliding seat 16, and the gear 17 meshes with the other end of the sliding seat 16. One end of the sliding seat 16 is threadedly connected to a lead screw 19, and the other end of the lead screw 19 is fixedly connected to a rocker arm 18.

[0023] The specific settings and functions of this embodiment will be described in detail below. The manufacturing process of the diode pins is shown in the attached figure. Figure 2As shown, after adjusting the distance between the two jacking seats 3, the inclined portion of the tip of the jacking seat 3 is used to press the pins of the diode, so that the two pins of the diode are stretched outward, and the distance between the outer sides of the two jacking seats 3 is the angle of the stretched pins after forming. When the diode is assembled on different chips for use, due to the different pin slot positions of the chips, the angle of the stretched pins needs to be different. The hand-held rocker 18 rotates the lead screw 19, and the sliding seat 16 is driven to move by the lead screw 19. The sliding seat 16 is in Z-shaped structure, which is limited on one side of the inner clamping plate 4 to ensure that the sliding seat 16 can slide linearly. During the sliding process of the sliding seat 16, the teeth at both ends are used to drive the gear one 15 and the gear two 17 to rotate, respectively. The gear one 15 drives the transmission rod two 10 to swing, and when the angle of the transmission rod two 10 is different, the distance between the two transmission rods two 10 will be different, so the distance between the two inner clamping plates 4 will be changed, and the distance between the tips of the two jacking seats 3 will also be changed. In this way, the formed pins can reach the appropriate distance to be inserted into the pin slots of different models. Similarly, the rotation of the gear two 17 can drive the transmission rod one 7 to swing, and the linkage rod 8 can simultaneously drive the two transmission rod one 7 to stretch, which synchronously adjusts the distance between the inner clamping plates 4, thereby achieving the effect of changing the angle of the stretched pins.

[0024] Embodiment two: as shown in Figure 3 and Figure 4 As shown, the top end of the base 1 is fixedly connected with a servo motor 9, and the bottom end of the two jacking seats 3 is fixedly connected with a baffle 6. The outer side wall of the baffle 6 is overlapped with a top wheel 5, and the bottom end of the top wheel 5 is fixedly connected with a synchronous wheel 12. The two synchronous wheels 12 are drivingly connected with a synchronous belt 11, and the output end of the servo motor 9 is fixedly connected with one of the synchronous belts 11. The top surface of the base 1 is fixedly connected with an overlapping frame 2, and the top surface of the overlapping frame 2 is slidingly connected with the bottom surface of the jacking seat 3. The inner side wall of the base 1 is slidingly connected with a sliding plate 14, and the sliding plate 14 is fixedly connected with a spring 13 between the baffle 6. The inner side wall of the base 1 is provided with a step, and the bottom surface of the sliding plate 14 slides on the top surface of the step.

[0025] The effect achieved by the whole embodiment is that the conveyor belt is arranged on one side of the base 1, and the diodes move with the conveyor belt, when the diodes on the conveyor belt are aligned with the lifting seats 3, the servo motor 9 drives the synchronous wheel 12 to rotate, the synchronous wheel 12 drives the two lifting wheels 5 to rotate at the same time, the protruding end of the lifting wheel 5 pushes open the baffle 6, so as to drive the two lifting seats 3 to move towards the diodes, the lifting force of the lifting wheel 5 on the lifting seat 3 is converted into the lifting force of the lifting seat 3 on the diode pin, so as to lift and support the diode pin, so that the diode can be smoothly installed on the pin groove, a speed reducer is arranged at the output end of the servo motor 9, so that the rotation speed of the lifting wheel 5 is consistent with the moving speed of the conveyor belt, when the lifting wheel 5 rotates one turn, the diode on the conveyor belt moves one station, ensuring that each diode is in time contact with the lifting seat 3 for processing, at the same time, the spring 13 is arranged at the other end of the baffle 6, when the lifting wheel 5 moves the baffle 6 to the inner wall of the base 1, the spring 13 is compressed, when the servo motor 9 drives the lifting wheel 5 to continue to rotate, the protruding part of the lifting wheel 5 is no longer fixed on the side wall of the baffle 6, the elastic force of the spring 13 can automatically reset the baffle 6, so that the lifting seat 3 can be separated from the diode pin, improving the overall processing efficiency.

[0026] The use method and working principle of the device are as follows: before processing, the rocker 18 is held and rotated, the screw rod 19 is driven to move the sliding seat 16, the gear one 15 and the gear two 17 are driven to rotate through the teeth at both ends of the sliding seat 16, the transmission rod two 10 is swung by the gear one 15, the interval of the supporting is adjusted, the transmission rod one 7 is swung by the gear two 17, and the interval of the inner clamping plate 4 is adjusted synchronously with the two transmission rod two 10.

[0027] When processing, the servo motor 9 is started, and the rotation speed of the lifting wheel 5 is consistent with the moving speed of the conveyor belt, the servo motor 9 drives the synchronous wheel 12 to rotate, the synchronous wheel 12 drives the two lifting wheels 5 to rotate at the same time, the protruding end of the lifting wheel 5 pushes open the baffle 6, drives the two lifting seats 3 to move towards the diodes, the lifting force of the lifting wheel 5 on the lifting seat 3 is converted into the lifting force of the lifting seat 3 on the diode pin, so as to lift and support the diode pin, when the lifting wheel 5 rotates one turn, the diode on the conveyor belt moves one station, ensuring that each diode is in time contact with the lifting seat 3 for processing.

[0028] Finally, when the servo motor 9 drives the lifting wheel 5 to continue to rotate, the protruding part of the lifting wheel 5 is no longer fixed on the side wall of the baffle 6, the elastic force of the spring 13 can automatically reset the baffle 6, so that the lifting seat 3 can be separated from the diode pin, the above process is repeated to complete the whole processing step.

[0029] The above merely describes preferred embodiments of the present application, and is not intended to limit the present application in other forms, and any skilled person in the art can modify or change the above disclosed technical content to equivalent embodiments applied to other fields with equivalent changes, but any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present application without departing from the technical scheme of the present application still falls within the protection scope of the present application.
