Description

Technical Field

[0001] The utility model relates to the technical field of chip detection, in particular to a chip appearance AOI detection device. Background Art

[0002] AOI is a device that detects common defects based on optical principles. It automatically scans the surface of the object to be inspected and collects images through a camera. After image analysis and processing, it detects surface defects of the object to be inspected for maintenance personnel to repair.

[0003] After production, existing chips often undergo surface wear and tear, requiring AOI inspection. However, since the chips require inspection on two sides, after inspecting one side, the chip must be manually flipped over and inspected again on the second side, reducing the efficiency of chip appearance inspection. Therefore, a chip appearance AOI inspection device is proposed. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of low efficiency of chip appearance inspection in the prior art and to propose a chip appearance AOI inspection device.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A chip appearance AOI inspection device comprises a base, two brackets are symmetrically fixed on the top of the base, and a collection camera is fixedly installed on the top of the two brackets, a slide is provided inside the base, and a lateral movement mechanism connected to the slide is provided inside the base, two support plates are symmetrically fixed on the top of the slide, a fixed frame is provided between the two support plates, and a chip clamping mechanism is provided inside the fixed frame, the two sides of the fixed frame are rotatably connected to the two support plates through a first rotating shaft and a second rotating shaft respectively, a gear is fixed on the end of the first rotating shaft, an upward extending fixed rod is fixed inside the base, and a rack is fixed on the upper end of the fixed rod.

[0007] Preferably, the lateral movement mechanism includes a motor and a screw, the motor is fixedly mounted on the inner wall of the base, the screw is arranged inside the base for lateral rotation, and one end of the screw is fixedly connected to the output end of the motor, and the slide is threadedly connected to the rod wall of the screw.

[0008] Preferably, the bottom of the slide is fixedly and slidably connected to the bottom inner wall of the base.

[0009] Preferably, the chip clamping mechanism includes clamping plates and springs, the clamping plates are symmetrically located inside the fixed frame, and one side of the two clamping plates is connected to the inner wall of the fixed frame via a spring.

[0010] Preferably, the gear and the rack are arranged in corresponding positions, and the gear and the rack can be meshed.

[0011] Preferably, a rotation damping sleeve is provided between the end of the second rotating shaft and the corresponding support plate.

[0012] Compared with the existing technology, the present invention provides a chip appearance AOI inspection device with the following beneficial effects:

[0013] 1. The chip appearance AOI detection device is provided with a slide, a fixed frame, a first rotating shaft, a second rotating shaft, a gear and a rack. The slide is driven by a horizontal movement mechanism, so that the fixed frame moves horizontally and passes under the first acquisition camera. At this time, the first acquisition camera can shoot and detect one side of the chip. The fixed frame engages the gear and the rack during the continuous horizontal movement. At this time, the gear can be rotated and the fixed frame can be rotated through the first rotating shaft and the second rotating shaft, so that the fixed frame can be automatically flipped between the two support plates. When the chip after flipping continues to move horizontally through the second acquisition camera, the appearance of the other side of the chip can be detected, thereby improving the efficiency of appearance detection.

[0014] 2. The chip appearance AOI detection device is equipped with a motor and a screw. When the motor is powered on, the motor drives the screw to rotate, and the screw drives the slide to move laterally inside the base, thereby enabling the chip to move laterally.

[0015] 3. The chip appearance AOI inspection device uses a clamping plate and a spring set inside a fixed frame. The chip is placed between the two clamping plates, and then the elastic force of the spring enables the clamping plate to clamp the chip inside the fixed frame, thereby improving the stability of the inspection.

[0016] The parts not involved in the device are the same as the existing technology or can be implemented by using the existing technology. The utility model can realize the automatic flipping operation of the chip, and can quickly complete the double-sided appearance inspection of the chip, thereby improving the efficiency of the inspection.

A gear 9 is fixed to the end of the first rotating shaft 7, and an upwardly extending fixed rod 10 is fixed inside the base 1. A rack 11 is fixed to the upper end of the fixed rod 10. The gear 9 and the rack 11 are arranged in corresponding positions, and the gear 9 and the rack 11 can be meshed. When the slide 4 is driven laterally inside the base 1, the fixed frame 6 moves laterally and passes under the first acquisition camera 3. At this time, the first acquisition camera 3 can shoot and detect one side of the chip. The fixed frame 6 engages with the gear 9 and the rack 11 during the continuous transverse movement. At this time, the gear 9 can be rotated and the fixed frame 6 can be rotated through the first rotating shaft 7 and the second rotating shaft 8, so that the fixed frame 6 can be automatically flipped between the two support plates 5. When the chip after flipping continues to move laterally through the second acquisition camera 3, the appearance of the other side of the chip can be photographed and detected, thereby improving the efficiency of appearance detection.

One side of the two clamping plates 14 is connected to the inner wall of the fixed frame 6 through the spring 15. When the chip is placed inside the fixed frame 6, the chip is placed between the two clamping plates 14. At this time, the clamping plates 14 compress the spring 15 outward, and then the elastic force of the spring 15 enables the clamping plates 14 to clamp the chip inside the fixed frame 6, thereby improving the stability of the inspection.
