[0002] After processing, the chip Figure 3 As shown, before formal packaging, the chip's appearance needs to be inspected, including surface scratches, dimensions, and whether bent pins are in place. Existing inspection methods typically perform separate chip inspections on different devices, making it impossible to perform multiple tests simultaneously on the same device. This results in relatively low inspection efficiency and the chip is prone to damage during the continuous transfer process. Summary of the Invention

[0010] The aforementioned chip shape automatic detection device is characterized in that the fourth servo assembly is connected to the slide via a connecting plate.

[0011] The beneficial effects of the present invention are as follows: By setting a horizontally movable carrier, it is convenient to realize the free movement of the chip to be inspected between the inspection station and the loading and unloading station, and two visual inspection modules are respectively set above and on the side of the inspection station. In combination with the rotatable carrier, all-round inspection of the chip is achieved at the same inspection station, which greatly improves the inspection efficiency and reduces the risk of multiple transfers of the chip during the inspection process.

[0015] The present invention will be further described below with reference to the accompanying drawings.

[0016] like Figure 1-Figure 2 As shown, a device for automatically inspecting chip shape includes a base 10, a slide 11 provided on the base 10, a slide 20 provided within the slide 11 that can move horizontally relative to the slide 11, a carrier 21 for carrying a chip provided on the slide 20, a first visual inspection component 31 that can move up and down relative to the slide 11 provided above the end of the slide 11, and a second visual inspection component 41 that can move horizontally relative to the slide 11 provided on the side of the end of the slide 11. The carrier 21 can rotate relative to the slide 20, and a first servo motor component 22 for driving its rotation is provided below the carrier 21.

[0017] will be as Figure 3The chip to be inspected is placed on the carrier 21 by a robot arm, and the slide 20 is controlled to drive the carrier 21 to move to the end of the slide 11. The first visual inspection component 31 is used to detect scratches and dimensions on the surface of the chip, and the second visual inspection component 32 is used to detect whether the bending condition of the bent pins meets the requirements. Since there are two rows of bent pins of the chip to be inspected, and they need to be visually inspected from different angles, the second visual inspection component 32 needs to combine the rotation of the carrier 21 and the movement of the slide 20 to perform image acquisition during inspection.

[0018] A fourth servo assembly 23 is provided at the bottom of the base 10 for driving the slide 20 to move horizontally along the slide 11. The fourth servo assembly is connected to the slide 20 via a connecting plate 24. The fourth servo assembly 23 drives the slide 20 to move precisely to the inspection station and, during the inspection process, can control the position of the chip relative to the two visual inspection components as needed.

[0019] In this embodiment, a bracket 30 is disposed at one end of the chute 11. The first visual inspection assembly 31 is slidably connected to the bracket 30. A second servo assembly 32 is also provided on the bracket 30 for driving the first visual inspection assembly 31 to move up and down relative to the bracket 30. During the inspection process, the second servo assembly 32 can be used to drive the first visual inspection assembly 31 to adjust its specific position as needed to meet different inspection requirements.

[0020] A frame 40 is provided on the other side of the end of the slide 11. The second visual inspection assembly 41 is slidably connected to the frame 40. A third servo assembly 42 is provided on the top of the frame 40 to drive the second visual inspection assembly 41 to move horizontally relative to the frame 40. After the carrier 21 rotates, if the position of the chip pins changes, the third servo assembly 42 drives the second visual inspection assembly 41 to move to a set position relative to the chip to be inspected, facilitating the detection of the bent position of the chip pins.

[0021] In summary, the present invention provides an automatic chip shape detection device, which realizes the detection of multiple parameters at different positions of the chip by setting two groups of movable visual detection components and coordinating the rotation of the carrier, thereby achieving the purpose of efficient and rapid detection.
