[0002] In the field of chip manufacturing, the inspection of chip appearance is of great significance. During the manufacturing, transportation or processing of chips, they may be hit, squeezed, etc., resulting in physical damage such as cracks and notches on the surface. These damages may affect the function and performance of the chip. The bending, deformation, missing or oxidation of the pins will affect the connection between the chip and the circuit board, resulting in poor electrical connection, which in turn affects the normal operation of the entire circuit.

[0024] To facilitate understanding of the present invention, a more comprehensive description of the present invention will be provided below. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to facilitate a more thorough and comprehensive understanding of the disclosure of the present invention.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0026] See also Figures 1 to 7, a visual inspection mechanism provided by an embodiment of the present invention is used to inspect the outer surface of a chip 40. The visual inspection mechanism includes a device body 10, an appearance inspection component 20 and a grasping component 30 for grasping the chip 40; the appearance inspection component 20 includes a top inspection part 21, a side inspection part 22 and a bottom inspection part 23; the top inspection part 21 is installed on the grasping component 30, and the bottom inspection part 23 and the side inspection part 22 are installed on the device body 10; the grasping component 30 is movably connected to the device body 10; before the grasping component 30 grasps the chip 40, the top inspection part 21 is used to inspect the top outer surface of the chip 40; when the grasping component 30 grasps and moves the chip 40 to the inspection area on the device body 10, the bottom inspection part 23 is used to inspect the bottom outer surface of the chip 40; when the grasping component 30 rotates, the side inspection part 22 inspects the side outer surface of the chip 40.

[0027] During the detection process, the grabbing component 30 grabs the chip 40 from the specified position; since the grabbing component 30 is movably connected to the device body 10, it can be flexibly moved and adjusted in position; before the grabbing component 30 grabs the chip 40, the top detection part 21 installed on the grabbing component 30 can detect the top outer surface of the chip 40; then, the grabbing component 30 moves the chip 40 to the detection area on the device body 10; at this time, the bottom detection part 23 fixed on the device body 10 detects the bottom outer surface of the chip 40, and the grabbing component is rotated so that the side detection part 22 detects the side outer surface of the chip 40.

[0028] This visual inspection mechanism, through the arrangement of the top, side and bottom inspection parts 23 under the coordinated action of the grasping component 30, can perform all-round inspection of the outer surface of the chip 40, minimize the inspection blind spots to the greatest extent, and ensure that the appearance of the chip 40 is defect-free; before the grasping component 30 grasps the chip 40, the top inspection part 21 located on the grasping component can perform inspection, saving the time of inspecting the top separately, and the overall process is more compact and efficient.

[0029] See also Figures 4 to 7The side detection unit 22 includes a detection mounting seat 220 mounted on the device body 10. The detection mounting seat 220 is provided with a Y-axis detection slide rail 221, and a sliding mounting seat 222 is slidably mounted on the Y-axis detection slide rail 221; an X-axis detection slide rail 223 is provided on the sliding mounting seat 222, and a side mounting seat 224 is slidably mounted on the X-axis detection slide rail 223, and a side detection component 225 is mounted on the side mounting seat 224. When performing side detection of the chip 40, first, the detection mounting seat 220 mounted on the device body 10 provides basic support for the entire side detection unit 22; the sliding mounting seat 222 on the Y-axis detection slide rail 221 can slide along the Y-axis direction, so that the components mounted on the sliding mounting seat 222 can adjust their position in the Y-axis direction; similarly, the X-axis detection slide rail 223 provided on the sliding mounting seat 222 enables the side mounting seat 224 to slide in the X-axis direction. Through the sliding combination of the X-axis and the Y-axis, the side detection member 225 installed on the side mounting seat 224 can be flexibly moved within a plane; thereby, it can accurately align with different side positions of the chip 40, thereby achieving comprehensive and accurate detection of various side positions of the chip 40.

[0030] A Y-axis detection motor 226 is mounted on the detection mounting base 220. One end of the housing of the Y-axis detection motor 226 is fixed to the side detection member 225, and the other end is fixed to the sliding mounting base 222. The rotor of the Y-axis detection motor 226 is threadedly connected to the side mounting base 224 via a screw rod 227. When the Y-axis detection motor 226 is started, its rotor rotates. Since the rotor is threadedly connected to the side mounting base 224 via the screw rod 227, the rotational motion of the rotor is converted into linear motion of the screw rod 227. The linear motion of the screw rod 227 pushes the side mounting base 224 to move along the Y-axis detection slide rail 221. When one end of the housing of the Y-axis detection motor 226 is fixed to the side detection member 225 and the other end is fixed to the sliding mounting base 222, the movement of the Y-axis detection motor 226 can be stably transmitted to the side mounting base 224, achieving precise Y-axis position adjustment.

[0031] A side detection motor 27 is mounted on the detection mount 220 at the bottom of the side detection member 225. The housing of the side detection motor 27 is fixed to the detection mount 220, and the rotor of the side detection motor 27 is threadedly connected to the sliding mount 222. The housing of the side detection motor 27 is fixed to the detection mount 220 and remains stationary. When the side detection motor 27 is started, its rotor begins to rotate. Because the rotor is threadedly connected to the sliding mount 222, the rotor's rotational motion is converted into linear motion of the sliding mount 222. Through the control of the side detection motor 27, the sliding mount 222 can be accurately driven to move along a specific track direction, thereby driving the side detection member 225 to the desired detection position, achieving accurate detection of the chip side.

[0032] A light shielding cloth 228 is installed on the detection mounting seat 220 opposite to the side detection member 225, and the bottom detection part 23 is installed on the detection mounting seat 220 at the bottom of the light shielding cloth 228. During the side detection process of the chip 40, the light shielding cloth 228 plays a role in blocking external light interference; when the side detection member 225 is working, stray light in the external environment may affect the accuracy and precision of the detection; the light shielding cloth 228 can effectively reduce the amount of interfering light entering the detection area, ensuring that the side detection member 225 obtains clear and accurate detection results; the bottom detection part 23 is installed on the detection mounting seat 220 at the bottom of the light shielding cloth 228. Such a layout can, to a certain extent, take advantage of the relatively stable light environment created by the light shielding cloth 228; at the same time, the light shielding cloth 228 can also prevent the bottom detection part 23 from being disturbed by unnecessary light from above or from the side.

[0033] See also Figures 1 to 5 The grabbing assembly 30 includes a Z-axis grabbing slide 31 installed on the device body 10, an X-axis grabbing bracket 32 ​​is slidably provided on the Z-axis grabbing slide 31, and an X-axis grabbing bracket 32 ​​is provided on the X-axis grabbing slide 33; a Y-axis grabbing bracket 34 is slidably provided on the X-axis grabbing slide 33, and a plurality of first Y-axis grabbing slides 35 are provided on the Y-axis grabbing bracket 34; a Y-axis grabbing fixed seat 36 is slidably provided on the first Y-axis grabbing slide 35, and a plurality of grabbing parts 38 are fixed on the Y-axis grabbing fixed seat 36. The device body 10 provides support for the entire grabbing assembly 30; the Z-axis grabbing slide 31 is installed on the device body 10, and the X-axis grabbing bracket 32 ​​can slide up and down in the Z-axis direction along the Z-axis grabbing slide 31; the X-axis grabbing slide 33 on the X-axis grabbing bracket 32 ​​allows the Y-axis grabbing bracket 34 to slide left and right in the X-axis direction; the multiple first Y-axis grabbing slides 35 on the Y-axis grabbing bracket 34 allow the Y-axis grabbing fixed seat 36 to slide back and forth in the Y-axis direction. Through the coordinated action of the three-axis slides in the Z-axis, X-axis, and Y-axis directions, the multiple grabbing members 38 fixed on the Y-axis grabbing fixed seat 36 can be flexibly moved in three-dimensional space; thereby, the grabbing member 38 can accurately reach the specified position of the chip 40 and accurately grab the chip 40.

[0034] The housing of the Y-axis detection motor 226 is mounted on the Y-axis grabbing fixed seat 36 , the rotor of the Y-axis detection motor 226 is connected to the grabbing member 38 , and the free end of the grabbing member 38 cooperates with the outer surface of the chip 40 . When it is necessary to grab the chip 40, the Y-axis detection motor 226 is started; the rotor of the Y-axis detection motor 226 rotates, and since the rotor is connected to the grabbing member 38, the rotation of the rotor drives the grabbing member 38 to move; the free end of the grabbing member 38 cooperates with the outer surface of the chip 40, and through the drive of the Y-axis detection motor 226, the free end of the grabbing member 38 approaches the chip 40 and contacts the outer surface of the chip 40, thereby realizing the grabbing action of the chip 40; multiple grabbing members 38 work at the same time, and can grab multiple chips 40 at the same time to improve the grabbing efficiency; they can also apply force evenly from different positions to ensure the stability and balance of the chip 40 during the grabbing process; the housing of the Y-axis detection motor 226 is installed on the Y-axis grabbing fixed seat 36, and the transmission method of connecting the rotor and the grabbing member 38 can reduce energy loss and improve the efficiency of the motor-driven grabbing member 38.

[0035] The top detection part 21 is installed on the Y-axis grabbing bracket 34 on one side of the grabbing member 38; a second Y-axis grabbing slide 340 is set on the Y-axis grabbing bracket 34 on one side of the first Y-axis grabbing slide 35, and the top detection part 21 is slidably set on the second Y-axis grabbing slide 340. The top detection part 21 is installed on the Y-axis grasping bracket 34 on one side of the grasping member 38, and can move with the grasping member 38 in the Y-axis direction, thereby maintaining a fixed relative position with the grasping member 38 and inspecting the top appearance of the chip 40 before the grasping process; the first Y-axis grasping slide 35 is used to realize the directional movement of the grasping member 38 in the Y-axis direction to complete the grasping action; and the second Y-axis grasping slide 340 set on the Y-axis grasping bracket 34 on the same side provides an independent moving track for the top detection part 21; when the grasping member 38 moves along the first Y-axis grasping slide 35, the top detection part 21 can slide on the second Y-axis grasping slide 340 as needed; the top detection part 21 is installed on one side of the grasping member 38, and can detect the top appearance of the grasped object at close range and in real time; by setting an independent second Y-axis grasping slide 340, the top detection part 21 can slide independently of the grasping member 38; this increases the flexibility of detection and can adjust the position of the detection part according to different detection requirements.

[0036] The top detection part 21 includes a top detection motor 210, a top detection fixed seat 211 and a top detection member 212; the top detection member 212 is slidably mounted on the second Y-axis grabbing slide rail 340 through the top detection fixed seat 211, the shell of the top detection motor 210 is fixed on the Y-axis grabbing bracket 34, and the rotor of the top detection motor 210 passes through the Y-axis grabbing bracket 34 and is threadedly connected to the top detection fixed seat 211. The shell of the top detection motor 210 is fixed on the Y-axis grabbing bracket 34 and remains stationary. When the top detection motor 210 is started, its rotor rotates. Since the rotor passes through the Y-axis grabbing bracket 34 and is threadedly connected to the top detection fixing seat 211, the rotation of the rotor will be converted into a linear sliding of the top detection fixing seat 211 on the second Y-axis grabbing slide 340. The top detection member 212 is installed on the top detection fixing seat 211, and the top detection member 212 is driven by the top detection motor 210 to achieve precise position adjustment along the second Y-axis grabbing slide 340. The fixed installation and threaded transmission method of the motor make the detection member more stable during movement, reducing shaking and deviation.

[0037] A detection lens 213 is provided on the top detection seat opposite the top detection member 212. The detection lens 213 can provide a clear and accurate image of the top of the object being detected; by adjusting the angle or position of the lens, detection of different angles and areas of the top can be achieved.
