Description

Technical Field

[0001] The present invention relates to the technical field of chip detection, and particularly relates to a chip detection device for electronic information engineering. Background Art

[0002] A chip, also known as an integrated circuit board, refers to an electronic component in which a circuit is fabricated on the surface of a semiconductor chip, which is a way to miniaturize a circuit. During the production and manufacturing process of chips, it is often necessary to detect the chips before they can be used for factory shipment. Common detections include appearance detection, characteristic detection, function detection, insulation detection, and temperature detection, etc. When performing appearance detection, traditionally, manual visual inspection is used to check whether the appearance is damaged and whether the pins are broken one by one. Since the chips are small, this makes the detection effect of manual inspection low and the detection accuracy poor. Therefore, we propose a chip detection device for electronic information engineering to solve the above problems. Summary of the Invention

On both of the two support plates, side plates are fixedly arranged. Between the two side plates, two rollers are rotatably arranged. The two rollers are symmetrically rotatably arranged at both ends of the side plates. On one side plate, a motor is fixedly arranged. The shaft of one of the rollers rotatably penetrates through the side plate and is fixedly connected to the output end of the motor. A conveyor belt is sleeved on the two rollers. A number of connecting rods are evenly and fixedly arranged on the conveyor belt. On each connecting rod, a placement table is fixedly arranged. The placement table is connected to the connecting rod through a fixing mechanism, and a placement groove corresponding to the chip is formed on the placement table. On one side of the side plate, a back plate is also fixedly arranged. On the back plate, a top plate is fixedly arranged. A camera is fixedly arranged on the lower wall of the top plate. The camera is arranged corresponding to the placement groove. On the side wall of the back plate, a connecting plate is also fixedly arranged. A magnifying glass is fixedly arranged at one end of the connecting plate. The magnifying glass is arranged below the camera. A fixing plate is also fixedly arranged on the lower wall of the top plate. A shutter switch corresponding to the camera is arranged on the fixing plate. A cleaning mechanism corresponding to the camera and the magnifying glass is also arranged on the top plate.

[0006] To better achieve the above object, the present invention adopts a further technical solution: The fixing mechanism includes a plurality of clamping blocks. A slot corresponding to the connecting rod is opened on the lower wall of each placement table. Two telescopic slots corresponding to the clamping blocks are symmetrically opened on the side wall of each connecting rod. The two clamping blocks are respectively slidably arranged in the two telescopic slots, and the two clamping blocks are both connected to the inner wall of the telescopic slot through a third spring. Card slots corresponding to the clamping blocks are opened on both side walls of each slot. One side wall of each clamping block is inclined. A pushing mechanism corresponding to the clamping block is arranged in each card slot. The pushing mechanism includes a plurality of pushing plates. The plurality of pushing plates are respectively slidably arranged in the plurality of card slots. A dial rod is fixedly arranged on the side wall of each pushing plate. The plurality of dial rods all slidably penetrate through the side wall of the placement table. Two strip-shaped sliding openings corresponding to the dial rods are symmetrically opened on the side wall of each placement table.

[0007] To better achieve the above object, the present invention adopts a further technical solution: The cleaning mechanism includes two cleaning plates. One cleaning plate is arranged in a long strip shape, and the other cleaning plate is arranged in a U shape. The two cleaning plates are connected by a connecting rod. A sliding rod is fixedly arranged on one side cleaning plate. The sliding rod is slidably arranged on the top plate. The two cleaning plates are respectively arranged in corresponding contact with the camera and the magnifying glass. The U-shaped opening of the U-shaped cleaning plate corresponds to the magnifying glass. A pushing plate is fixedly arranged on the lower wall of the lower cleaning plate. The lower end side wall of the pushing plate is inclined. The placement table corresponds to the inclined side wall of the pushing plate. A sliding lifting mechanism corresponding to the sliding rod is arranged on the top plate.

[0008] To better achieve the above object, the present invention adopts a further technical solution: The sliding lifting mechanism is a sliding plate. The sliding plate is slidably arranged on the side wall of the sliding rod through a slider. A side slot corresponding to the slider is opened on the side wall of the sliding rod. The slider is connected to the side wall of the side slot through a first spring. The sliding plate is also slidably arranged on the top plate.

[0009] To better achieve the above object, the present invention adopts a further technical solution: A lens cleaning cloth is fixedly arranged on the side walls of the two cleaning plates close to the camera and the magnifying glass.

[0010] The beneficial effects of the present invention are as follows: the push plate is controlled by setting a lever, and the push plate can be driven to push out the card block by toggling the lever, so that the corresponding placement table can be replaced according to the type and size of the chip, thereby improving adaptability, and then the cooperation of the conveyor belt and the connecting rod can realize continuous conveying of the chip to the lower side of the camera, and when the placement table moves to the inclined side wall of the push plate, the push plate drives the two cleaning plates to move toward one side of the camera, and as the placement table reaches directly below the camera, the slide bar is pushed to the other end of the slide slot, at which time the cleaning plate completes wiping the magnifying glass and the camera, and the upper cleaning plate at this time will squeeze and fix The shutter switch on the board controls the camera to automatically take pictures, so that the enlarged picture of the chip can be quickly obtained. When the slide bar moves to the end close to the shutter switch and reaches the groove, the placement table pushes the inclined side wall of the push plate to drive the slide bar to move up, so that the placement table can pass the push plate. After the placement table passes the push plate, the slide bar is reset downward under the action of the first spring, and then slides and resets to the initial position under the action of the second spring, and then the next chip can be enlarged and photographed. The inspector only needs to watch the enlarged picture to complete the appearance inspection of the chip, which greatly improves the efficiency and accuracy of the inspection.
