Description

Technical Field

[0001] The utility model relates to the technical field of chip detection, in particular to a transmission mechanism for chip detection. Background Art

[0002] Chips are a form of packaging for integrated circuits. They integrate electronic components, circuits, and systems on a tiny silicon chip to realize the functions of electronic devices. Chips are an important part of modern technology and are ubiquitous, affecting people's production and life. Since the quality and reliability of chips are related to the operational stability of the entire product, in order to ensure the quality and reliability of chips, they need to be inspected. Visual inspection is a fully automatic inspection solution based on computer vision technology. Through visual inspection, various defects on the surface of the chip, such as flaws, damage, etc., can be detected. When inspecting chips, the chips need to be transported one by one, so a transport device is required.

[0003] Existing chips are often transported by conveyor belts and then delivered to a detection mechanism, which then performs visual inspection on the chips. However, when the chips are transported on the conveyor belt, the position of the chips may shift, which may reduce the visual inspection effect of the chips. At the same time, when the chips are visually inspected, the other side of the chips needs to be inspected. Utility Model Content

[0010] Preferably, a second mounting plate is fixedly mounted on one end of the outer wall of the rotating rod, and an electric vacuum suction cup is arranged at the bottom end of the second mounting plate.

[0011] Preferably, four pillars are fixedly installed on the bottom end of the conveying frame, the second frame is fixedly connected to the conveying frame, and the fixing plate is fixedly connected to the conveying frame.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, the chip is first placed on a side close to the second visual inspection camera. When the chip is transported on a conveyor belt and needs to be visually inspected, the position of the chip may be slightly offset when it moves on the conveyor belt. At this time, the first motor can be turned on according to the position of the chip on the conveyor belt. The first motor drives the threaded screw to rotate. During the rotation, the threaded screw drives the second visual inspection camera to move through the slider, so that the position of the second visual inspection camera can be adjusted according to the position of the chip, avoiding the problem of reduced visual inspection effect due to chip offset. When the chip moves to the bottom of the second visual inspection camera, the chip can be visually inspected.

[0014] 2. In the utility model, after one side of the chip is inspected, it is necessary to inspect the other side of the chip. When the chip moves to the flipping mechanism, the second electric push rod is first turned on, and the second electric push rod drives the electric vacuum suction cup to move above the chip. Then the first electric push rod is turned on, and the first electric push rod drives the electric vacuum suction cup to move downward until it contacts the surface of the chip. At this time, the electric vacuum suction cup is turned on, and the electric vacuum suction cup adsorbs the chip. The first electric push rod is turned on again to drive the electric vacuum suction cup and the chip to rise to a suitable position. At this time, the second motor is turned on, and the second motor can drive the chip to rotate to expose the other side of the chip. Then the second electric push rod is turned on to move the chip to the bottom of the first visual inspection camera. At this time, the other side of the chip can be inspected by the first visual inspection camera. When the inspection of the other side of the chip is completed, the second motor can be started again to flip the chip over. Then the first electric push rod is turned on to drive the chip to move downward. At this time, the electric vacuum suction cup is closed, and the chip falls off the electric vacuum suction cup and falls onto the conveyor belt, so that the chip can be transported.
