Description

Technical Field

[0001] The utility model relates to the technical field of diode manufacturing, in particular to a diode waste lead screening device. Background Art

[0002] During the diode forming process, the leads on both sides must be trimmed to achieve the required dimensions. After trimming, the finished diodes are mixed with the waste leads, requiring manual screening. However, manual screening can easily cause deformation of the finished products and wear of the printed markings, significantly increasing the subsequent tube sorting workload and creating the risk of missed inspections. Utility Model Content

[0003] In view of the above problems, the purpose of the present invention is to provide a diode waste lead screening device that can effectively separate diodes and waste leads and is easy to use.

[0004] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: a diode waste lead screening device, comprising a first connecting plate, a second connecting plate and a screen, the screen comprising a plurality of horizontally arranged blocking columns, one end of the blocking column passing through the second connecting plate and fixedly connected to the first connecting plate, the other end of the blocking column being provided with an upward bending section, and the first connecting plate being provided with a vibrator and a flip cylinder.

[0005] In the above technical solution, the diameter of the blocking pillars is 3 mm, and the gap between adjacent blocking pillars is 4.3-4.8 mm.

[0006] In the above technical solution, the screen is tilted downward from one end of the connecting plate, and the inclination angle with the horizontal is 30°.

[0007] In the above technical solution, the vibrator is a pneumatic vibrator.

[0008] In the above technical solution, a collecting box is provided at the lower part of the screen, a diode bin and a waste lead bin are provided in the collecting box, and a partition is provided between the diode bin and the waste lead bin.

[0009] In the above technical solution, the screen is arranged on the upper part of the waste lead bin and can be turned over to the upper part of the diode bin under the drive of the turning cylinder.

[0010] In the above technical solution, the rotation angle of the flip cylinder is 0 to 90 degrees.

[0011] In the above technical solution, the first connecting plate and the second connecting plate can be mounted on the side plates of the collection box.

[0012] To sum up, the technical solution of the present invention has the following beneficial effects compared with traditional technical means: the present invention is arranged at the outlet of the diode processing machine. When in use, the diodes and waste leads fall onto the screen from the outlet at the same time. The screen screens out the waste leads under the action of the vibrator, and the diodes fall into the bending section. The flipping motor flips the screen regularly to guide the diodes into the corresponding diode bin. This can effectively screen the diodes and waste leads, greatly improving work efficiency.

DETAILED DESCRIPTION

[0020] The following is based on the ideal embodiment of the present invention. Through the following description, relevant personnel can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the content of the specification, but must be determined according to the scope of the claims.

[0021] The present invention will be further described with reference to the following drawings:

[0022] like Figures 1 to 5As shown, a diode waste lead screening device has a first connecting plate 100, a second connecting plate 200 and a screen 300. The screen 300 includes a plurality of horizontally arranged blocking columns 310. One end of the blocking column 310 passes through the second connecting plate 200 and is fixedly connected to the first connecting plate 100. The other end of the blocking column 310 is provided with an upward bending section 311. The first connecting plate 100 is provided with a vibrator 400 and a flip cylinder 500.

[0023] The diameter of the blocking posts 310 is 3 mm, and the gap between adjacent blocking posts 310 is 4.3 to 4.8 mm. The actual spacing is set to 4.5 mm. The diameter of the diode colloid is 5.2 mm. If the spacing between the blocking posts 310 is too large, the finished product may easily fall into the waste lead bin 620 of the collection box 600 by mistake, and if the spacing is too small, the waste leads 710 may not fall cleanly.

[0024] The screen 300 is tilted downward from one end of the first connecting plate 100 and has an inclination angle of 30° with the horizontal, which can accelerate the falling speed of the waste lead 710 and avoid material accumulation.

[0025] The vibrator 400 is a pneumatic vibrator, which is smaller in size and easier to install.

[0026] A collecting box 600 is provided at the lower portion of the screen 300 . A diode bin 610 and a waste lead bin 620 are provided in the collecting box 600 . A partition 630 is provided between the diode bin 610 and the waste lead bin 620 .

[0027] The screen 300 is disposed on the upper portion of the waste wire bin 620 and can be flipped to the upper portion of the diode bin 610 by the driving of the flip cylinder 500 .

[0028] The rotation angle of the tilting cylinder 500 is 0-90°.

[0029] The first connecting plate 100 and the second connecting plate 200 can be mounted on the side plates of the collection box 600 .

[0030] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations.
