During the chip production process, the inspection device continuously inspects different chips. If each chip needs to be photographed from multiple surfaces, the chip inspection speed will be greatly slowed down, delaying the normal production of the chip. Summary of the invention

[0037] Embodiment 1

[0038] In order to accelerate the speed of the camera for photographing multiple sides of the chip, please refer to Figures 1-3 As shown, the purpose of this embodiment is to provide an image reflection device for multi-faceted detection of the chip, including a base 1. A reflection device 2 is arranged on the base 1. The base 1 undertakes the chip and fixes the position of the chip on the base 1. The reflection device 2 includes a number of reflection mechanisms. The number of reflection mechanisms is symmetrically arranged around the position center of the chip. The reflection mechanisms reflect the side walls of the chip, so that the camera can photograph multiple sides of the chip. At the same time, the base 1 drives the number of reflection mechanisms to move on the base 1, so that the number of reflection mechanisms adjusts their positions according to the size of the chip, enabling the device to undertake chips of different sizes with the base 1, enabling the reflection device 2 to emit light to chips of different sizes. At the same time, during the movement of the reflection mechanisms, the number of reflection mechanisms is always symmetrically arranged around the chip center, and according to the number of chip sides to be detected, the reflection angle of the reflection mechanisms is adjusted so that the reflection mechanisms emit the bottom surface of the chip.

[0039] By reflecting the sides and bottom of the chip, the situations of the sides and bottom of the chip are obtained, enabling the camera to photograph the situations of multiple sides and the bottom of the chip without adjusting the position of the camera when photographing the chip, reducing the operations of the camera for photographing the sides and bottom of the chip, accelerating the speed of the camera for photographing the chip, and thus accelerating the detection speed of the chip.

[0040] The structures of the base 1 and the reflection device 2 are refined below to enable the base 1 and the reflection device 2 to achieve the above-described effects. Figures 1-14 As shown,

[0041] The base 1 includes a bottom plate 11, a middle block 15 is fixed at the center position of the upper side of the bottom plate 11, the middle block 15 is square, a lifting frame 16 is arranged on the middle block 15, a lifting threaded rod 17 is threadedly connected to the bottom of the lifting frame 16, the lifting threaded rod 17 is rotatably arranged on the middle block 15, and the lifting threaded rod 17 is driven to rotate by a motor, and the lifting frame 16 and the middle block 15 are connected by a plurality of sliding pins, and when the lifting threaded rod 17 rotates, the lifting frame 16 is driven to move upward, and the lifting frame 16 undertakes the chip, and at the same time, when the lifting threaded rod 17 rotates, the lifting frame 16 is driven to move upward, and the chip is received by the lifting frame 16. A suction cup is fixed at the upper end of the lifting frame 16. When the chip is placed on the lifting frame 16, the suction cup on the lifting frame 16 absorbs the chip to fix the position of the chip on the lifting frame 16. When the motor drives the lifting threaded rod 17 to rotate, the lifting threaded rod 17 drives the lifting frame 16 away from the middle block 15, so that the lifting frame 16 lifts the chip away from the middle block 15, and the distance between the chip and the middle block 15 is increased. At the same time, during the movement of the lifting frame 16, the sliding pin limits the position of the lifting frame 16 to improve the stability of the movement of the lifting frame 16.

[0042] The reflecting mechanism comprises a moving plate 21, the bottom of the moving plate 21 is parallel to the upper side of the bottom plate 11, the side wall of the moving plate 21 is parallel to the side wall of the middle block 15, and a plurality of moving plates 21 are arranged symmetrically, and one side of one moving plate 21 contacts the side wall of another adjacent moving plate 21, that is, a plurality of moving plates 21 are combined to form a windmill-like structure, and a mounting frame 23 is hingedly connected to a side of the upper side of the moving plate 21 close to the middle block 15, and a reflector is mounted on the mounting frame 23, and a clamping member between the mounting frame 23 and the moving plate 21 is provided. The maximum angle is 45 degrees. When the chip is placed on the lifting frame 16, the inclined reflector reflects the side image of the chip so that the reflected image is received by the camera. At this time, the camera shoots the front of the chip, that is, the side wall of the chip away from the middle block 15. At this time, the images of the five sides of the chip are obtained. By shooting the chip in this way, the information of the five sides of the chip can be obtained at one time, eliminating the trouble of the camera shooting multiple sides of the chip, speeding up the shooting speed of the chip, and thus speeding up the detection speed of the chip.

[0043] Meanwhile, in order to reduce the images reflected by the mirror on the mounting frame 23 to other devices when the mirror on the mounting frame 23 reflects the image on the side of the chip, for example, there is a space between the mirrors on the two mounting frames 23, and the mirror will reflect the image passing through the space together, which will make the image content received by the camera messy. In order to reduce the messiness of the images reflected by the mirror, several mounting frames 23 are arranged centrosymmetrically around the center of the middle block 15, and one end of one mounting frame 23 is in contact with the side wall of another mounting frame 23, and the end of the mounting frame 23 in contact with the side wall of another mounting frame 23 is set in an inclined shape. By setting one end of the mounting frame 23 in an inclined shape and fitting one end of the mounting frame 23 to the side wall of another mounting frame 23, the gap at the contact position between the two mounting frames 23 is avoided, thereby reducing the messy images reflected by the mirror, so that the camera can capture accurate information on the side wall of the chip.

[0044] During the production process of the chip, there will be situations where the sizes are different. If each chip corresponds to a detection device, the detection cost will increase. Considering this point in this case, several threaded rods 12 are provided on the bottom plate 11. The threaded rods 12 are rotatably arranged on the bottom plate 11 through hinge frames, and several threaded rods 12 are arranged centrosymmetrically around the center of the middle block 15. Tapered wheels 13 are installed at both ends of the threaded rods 12. Several threaded rods 12 are connected end to end to form a square, and the positions where two threaded rods 12 are connected are meshed with each other through the tapered wheels 13. A driving motor is installed on one side of one of the threaded rods 12, and a driving gear is installed on the rotating shaft of the driving motor. The driving gear is tapered, and the driving gear drives one of the tapered wheels 13 to rotate. By driving the driving motor to drive the driving gear to rotate, the driving gear drives the threaded rod 12 to rotate through one of the tapered wheels 13. The rotating threaded rod 12 transmits power through the meshed tapered wheels 13, so that several threaded rods 12 rotate together.

[0045] A lead screw nut 211 is fixed to the bottom of the moving plate 21. The lead screw nut 211 is threadedly connected to the lead screw rod 12. When the lead screw rod 12 rotates, it drives the moving plate 21 to move along the axis direction of the lead screw rod 12. During the movement of the lead screw nut 211, the lead screw nut 211 drives the moving plate 21 to move along the axis direction of the lead screw rod 12. During the rotation of the lead screw rod 12, several moving plates 21 move together. When the moving plate 21 moves, one end side wall of a moving plate 21 slides on the side wall of another moving plate 21. At the same time, in order to enable the moved moving plate 21 to still drive the mounting frame 23 to reflect the side of the chip, at the position where the lead screw rod 12 is provided, the position where the two lead screw rods 12 are connected corresponds to the center position of the side wall of the middle block 15, and the center position of the lead screw rod 12 corresponds to the corner of the middle block 15. During the movement of the moving plate 21, several moving plates 21 are always centrosymmetric about the center of the middle block 15. At the same time, sliding frames 14 are provided on both sides of the lead screw rod 12. The sliding frames 14 are fixed to the bottom plate 11. A sliding plate 212 corresponding to the position of the sliding frame 14 is fixed to the bottom of the moving plate 21. The sliding plate 212 is slidably arranged between the sliding frames 14. Through the mutual cooperation of the sliding plate 212 and the sliding frames 14, the stability of the movement of the moving plate 21 is improved, ensuring the smooth movement of the moving plate 21.

[0046] When using the above structure to reflect the chip, the camera can obtain the side and top images of the chip, but cannot obtain the bottom image of the chip. In order to enable the camera to further obtain the full picture of the chip, a fixed plate 22 is fixed to the upper side of the moving plate 21 near the middle block 15. An adjusting member is provided on the side of the mounting frame 23 away from the middle block 15. The adjusting member adjusts the inclination angle of the mounting frame 23. By adjusting the inclination angle of the mounting frame 23 through the adjusting member, the reflecting mirror changes the reflecting angle, so that the reflecting mirror can not only reflect the side of the chip, but also reflect a partial image of the bottom of the chip, as Figure 14 shown, so as to enable the camera to obtain the images of 6 faces of the chip, so as to facilitate the camera to obtain the full picture of the chip and achieve the full picture detection of the chip.

[0047] The adjusting member includes a plurality of hinge rods hinged to the side wall of the mounting frame 23. The plurality of hinge rods are connected by a pull rod 24. A pull frame 25 is hinged to the pull rod 24. A fixing ring 26 fixed to the fixing plate 22 is arranged inside the pull frame 25. A rotating ring 27 is rotatably arranged inside the fixing ring 26. A conveying screw rod 29 is threadedly connected inside the rotating ring 27. One end of the conveying screw rod 29 is rotatably arranged on the pull frame 25. The other end of the hinge rod is hinged with a slider. The slider is slidably arranged on the fixing plate 22. And the other end of the conveying screw rod 29 is fixed to one of the sliders. A gear 28 is meshed with the rotating ring 27. A motor for driving the gear 28 to rotate is arranged on one side of the gear 28. When the rotating ring 27 rotates, it drives the conveying screw rod 29 to move along the axis direction, so that the pull frame 25 drives the pull rod 24 and the hinge rod to move. The moving hinge rod pulls the mounting frame 23, changing the inclination angle of the mounting frame 23.

[0048] When the adjusting member adjusts the angle of the mounting frame 23, the motor drives the gear 28 to rotate, so that the gear 28 drives the rotating ring 27 to rotate in the fixing ring 26. The rotating rotating ring 27, through the threaded connection with the conveying screw rod 29, adjusts the conveying screw rod 29 to translate in the fixing ring 26. During the translation of the conveying screw rod 29, the conveying screw rod 29 pulls the slider and pushes the pull frame 25, so that the pull rod 24 drives the hinge rod to move. The moving hinge rod pulls the mounting frame 23, changing the included angle between the mounting frame 23 and the moving plate 21.

[0049] In order to enable the reflector to clearly reflect the bottom situation of the chip, during the flipping process of the mounting frame 23, the lifting frame 16 drives the chip away from the middle block 15, expanding the distance between the middle block 15 and the chip, and also expanding the distance between the chip and the reflector, so as to facilitate the reflector to reflect the bottom situation of the chip.

[0050] By adjusting the inclination angle of the mounting frame 23 through the adjusting member, the included angle between the mounting frame 23 and the moving plate 21 is reduced. At the same time, the lifting frame 16 drags the chip away from the middle block 15, so that the mounting frame 23 can reflect the image of the bottom of the chip onto the camera, facilitating the camera to obtain the content of the 6 faces of the chip, achieving the acquisition of the full - range image of the chip, reducing the trouble of the camera shooting multiple faces of the chip, accelerating the shooting speed of multiple side walls of the chip, and thus improving the detection speed of the chip.

Those skilled in the art should understand that the present invention is not limited by the above embodiments, and the above embodiments and the descriptions in the specification are only preferred examples of the present invention, which are not used to limit the present invention.
