[0019] The utility model provides Figure 1-4 A semiconductor marking machine for reducing wave light intensity is shown, comprising a marking platform 1 and a marking head 2, a conveying groove is provided at the upper end of the marking platform 1, a conveying mechanism is arranged in the conveying groove, a lifting mechanism is fixedly arranged at the rear side of the marking platform 1, the marking head 2 is fixedly arranged at the lower side of a lifting plate 3 in the lifting mechanism, the lower side of the lifting plate 3 is connected to a light-shielding shell 4 through an elastic sliding mechanism, and an opening is provided in the middle part of the upper side of the light-shielding shell 4 for the marking head 2 to slide through.

[0020] like Figure 1-Figure 3 As shown, the lifting mechanism includes an electric slide rail 5, an electric slider 6, a connecting plate 7 and a lifting plate 3. The electric slide rail 5 is vertically fixed on the rear side of the marking table 1, the electric slider 6 is slidably installed above the front side of the electric slide rail 5, the connecting plate 7 is fixed at the front end of the electric slider 6, and the front end of the connecting plate 7 is fixedly connected to the lifting plate 3.

[0021] like Figure 2 As shown, the elastic sliding mechanism includes two round rods 8 and two springs 9. The two round rods 8 are respectively vertically fixed on the left and right sides of the upper end of the light-shielding shell 4. Two round grooves for the round rods 8 to slide into are provided on the lower side of the lifting plate 3. The two springs 9 are respectively movably mounted on the two round rods 8. The upper and lower ends of each spring 9 are respectively fixedly connected to the lifting plate 3 and the light-shielding shell 4 to avoid squeezing and damage to the light-shielding shell 4 when the light-shielding shell 4 contacts the conveying roller 11.

[0022] like Figure 2 As shown, an annular shading pad 10 is fixedly arranged on the surrounding side walls of the opening, and the annular shading pad 10 is in contact with and slidably arranged on the surrounding side walls of the marking head 2, which can improve the shading effect.

[0023] like Figure 2 and Figure 4As shown, the conveying mechanism includes a plurality of conveying rollers 11, which are longitudinally arranged in the conveying trough, and a rotating shaft is fixedly inserted at the end face of each conveying roller 11. The front and rear ends of each rotating shaft are rotatably connected to the front and rear sides of the conveying trough respectively through bearings, and the two adjacent rotating shafts are mutually transmitted through a chain and two sprockets. A driving component that can drive the plurality of conveying rollers 11 to rotate is provided on the rear side of the marking table 1, which can drive the plurality of conveying rollers 11 to rotate synchronously in the same direction, thereby completing the conveying of semiconductors.

[0024] like Figure 2-Figure 4 As shown, a vertically arranged baffle 13 is arranged on the right side below the shading shell 4, and the baffle 13 is slidably inserted between two of the conveying rollers 11. A strip-shaped opening longitudinally aligned with the baffle 13 is opened on the rear side of the conveying groove, and an L-shaped rod 14 is arranged on the rear side of the marking platform 1. The front end of the longitudinal part of the L-shaped rod 14 slides through the strip opening and is fixedly connected to the rear end of the baffle 13. An elastic telescopic rod 12 is fixedly arranged on the rear end of the lower side of the connecting plate 7, and the lower end of the elastic telescopic rod 12 is fixedly connected to the upper side of the horizontal part of the L-shaped rod 14. When the lifting plate 3 drives the marking head 2 and the shading shell 4 to be in the upper position, the upper end of the baffle 13 extends to the top of the marking platform 1, and when the conveying roller 11 conveys the semiconductor to the baffle 13, the baffle 13 will be halfway. The conductor is blocked so that the semiconductor is located below the marking head 2. At this time, the transmission of the conveying roller 11 is stopped. When the lifting plate 3 drives the marking head 2 and the shading shell 4 to move downward, the connecting plate 7 will drive the baffle 13 to move downward through the elastic telescopic rod 12 and the L-shaped rod 14, so that the baffle 13 shrinks to the conveying groove, and the elastic telescopic rod 12 is in a compressed state. When the marking head 2 completes marking the semiconductor, the lifting plate 3 starts to drive the marking head 2 and the shading shell 4 to move upward, the potential energy of the elastic telescopic rod 12 is released, and the baffle 13 does not move. At this time, starting the conveying roller 11 can convey the semiconductor, and the lifting plate 3 continues to move upward until it drives the baffle 13 to move upward, thereby achieving a blocking effect on the conveyed semiconductor.

[0025] The working principle of the utility model is as follows: when in use, the semiconductor is transported to the bottom of the marking head 2 through the conveying roller 11, and the electric slide 6 is driven to move downward by the electric slide rail 5. The electric slide 6 drives the marking head 2 to move downward through the connecting plate 7 and the lifting plate 3. At this time, the lifting plate 3 also drives the light-shielding shell 4 to move downward through two springs 9 until the light-shielding shell 4 is against the surface of the conveying roller 11. At this time, the semiconductor is marked by the marking head 2 again, and the light-shielding shell 4 will block the wave light generated by the marking head 2 to prevent the wave light from affecting people.
