Description

Technical Field

[0001] This utility model belongs to the technical field of semiconductor component auxiliary manufacturing equipment, specifically relating to an eccentric reciprocating propulsion device. Background Technology

[0002] A diode is one of the simplest semiconductor devices, consisting of a PN junction, electrode leads, and a package. It is a two-terminal electronic device with unidirectional conductivity. The diode leads are metallic conductor structures that connect the internal PN junction of the diode to the external circuit, and are usually made of highly conductive materials.

[0003] The feeding of diode leads is usually achieved by levers, cams, and rocker arms, which drive the connecting rod and the wire clamping mold to move back and forth. The wire clamping mold holds the wire and moves back and forth to feed it. However, in the current feeding structure, when the rocker arm and cam are used together, the range of reciprocating movement cannot be effectively adjusted because the dimensions of the rocker arm and cam are fixed. Unless the cam or rocker arm is replaced, the movement range of the wire clamping mold cannot be adjusted when dealing with diode leads of different sizes and specifications, thus making it impossible to perform the corresponding cutting operation. Therefore, there is an urgent need for a reciprocating propulsion device for feeding diode leads. Utility Model Content

[0037] Example

[0038] like Figure 1-2 As shown, the eccentric reciprocating propulsion device provided by this utility model includes: a drive shaft 1, a limiting frame 2, a slider 3, a limiting member 5, a driven shaft 6, and a linkage mechanism 7.

[0039] The limiting frame 2 is fastened to the drive shaft 1. A groove 3 is provided on the side of the limiting frame 2 away from the drive shaft 1. The limiting frame 2 is a rectangular block with the groove 3 carved out. The bottom of the groove 3 has a certain thickness. The drive shaft 1 is connected to the bottom of the limiting frame 2 and tightened. The drive shaft 1 is rotated and fixed by multiple bearing seats 10. The end of the drive shaft 1 away from the limiting frame 2 is used to connect a drive motor and other components to provide driving force. The length direction of the groove 3 is orthogonal to the axis direction of the drive shaft 1, so that the rotation of the drive shaft 1 can drive the entire limiting frame 2 to rotate. There is a rotation center in the groove 3 that remains stationary.

[0040] The slider 3 is slidably disposed in the groove 3. The width of the slider 3 is consistent with the width of the groove 3, and the length of the slider 3 is less than the length of the groove 3. The slider 3 is used to reciprocate along the length direction of the groove 3. One end of the driven shaft 6 is fixedly connected to the slider 3, and the shaft core of the driven shaft 6 is parallel to the shaft core of the drive shaft 1. The other end of the driven shaft 6 is connected to the linkage mechanism 7. During the rotation of the limit frame 2, it is used to drive the linkage mechanism 7 to reciprocate.

[0041] Specifically, it is also connected to the limiting frame 2 by a limiting member 5 to limit the position of the slider 3 in the limiting frame 2;

[0042] One end of the linkage mechanism 7 is rotatably connected to the other end of the driven shaft 6, and the other end of the linkage mechanism 7 serves as the working end.

[0043] By fixing the limiting frame 2 to the drive shaft 1, the slider 3 can slide in the slide groove 3, and the driven shaft 6 is connected to the slider 3, thereby adjusting the eccentric distance between the drive shaft 1 and the driven shaft 6. Then, the limiting member 5 is used to fix the slider 3, thereby making it convenient and quick to adjust the eccentric distance of the entire propulsion device, and thus quickly adjusting the range of propulsion distance.

[0044] Specifically, two limiting members 5 are provided, and the two limiting members 5 are respectively provided at both ends of the slide groove 3. The ends of the limiting members 5 abut against both ends of the slider 3 to limit the position of the slider 3 in the slide groove 3. The limiting members 5 can be implemented by bolts, etc. The bolts are screwed into the limiting frame 2, and the ends of the bolts abut against the slider 3 to ensure the stability of the slider 3 in the slide groove 3. There are two bolts provided and they are located at both ends of the slide groove 3, which can prevent the slider 3 from moving to both ends and thus keep it stable.

[0045] It also includes a pad 8, which is disposed between the limiting member 5 and the slider 3. The pad 8 increases the contact area and reduces the length of the limiting member 5 extending into the slide groove 3, thereby preventing the limiting member 5 from shaking and ensuring stability.

[0046] The drive shaft 1 is fastened to the center of the slide groove 3 in the limiting frame 2, so that the slider 3 can be adjusted to either end of the slide groove 3.

[0047] To ensure the precise adjustment of the slider 3, the limiting frame 2 is provided with scales at intervals along the length of the slide groove 3 on the side near the slide groove 3. The scales indicate the distance of the slider 3 from the original center position, that is, the distance of deviation between the driven shaft 6 and the drive shaft 1 after adjustment.

[0048] In this embodiment, a sliding mechanism 9 is also included, which includes a slide block 901 and a slide table 902.

[0049] A limiting groove 903 is formed on the upper edge of the slide block 901 orthogonal to the axis of the driven shaft 6. The slide table 902 is slidably connected to the slide block 901. The slide table 902 is provided with a limiting protrusion 904 that matches the limiting groove 903. The limiting protrusion 904 and the limiting groove 903 can ensure that the slide table 902 slides on the slide block 901 along the length direction of the limiting groove 903. The working end of the linkage mechanism 7 is rotatably connected to the slide table 902. The linkage mechanism 7 drives the slide table 902 to reciprocate. The slide table 902 makes it easier to arrange subsequent parts.

[0050] The slide block 901 has an oblong hole 905 orthogonal to the axis of the driven shaft 6, that is, the long axis of the oblong hole is consistent with the reciprocating motion direction of the slide table 902. The slide table 902 is provided with a boss 906 passing through the oblong hole 905. The working end of the linkage mechanism 7 is rotatably connected to the boss 906, so that the setting of the boss 906 does not affect the upper surface of the slide table 902.

[0051] In this embodiment, the linkage mechanism 7 includes a connecting block 701 and a rod 703.

[0052] A bearing 702 is provided in the connecting block 701. The bearing 702 is connected to the driven shaft 6. The connecting block 701 is mainly used to install the bearing 702, so as to facilitate the rotatable connection between the driven shaft 6 and the rod body 703. The rod body 703 is arranged in a direction perpendicular to the axis of the driven shaft 6. One end of the rod body 703 is screwed to the connecting block 701, and the other end is rotatably connected to the slide table 902.

[0053] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
