[0039] The test sorting machine is a type of chip processing equipment with the functions of processing, testing, inspection, and sorting. When the existing test sorting machine inspects the outside of the chip (four circumferential sides, bottom (back)), especially the four circumferential sides of the chip, it can only inspect a few surfaces each time, and the camera needs to shoot multiple times to capture the four circumferential sides of the chip. In this way, the chip inspection process stays at this link for a long time, resulting in a long inspection time. When the test sorting machine is fully loaded, the inspection structure will affect the working efficiency of the test sorting machine.

[0040] The utility model provides a visual detection structure for testing a sorting machine.

[0041] See also Figure 1 , Figure 2 , Figure 4 In one embodiment of the present utility model, the visual detection structure includes:

[0042] The mounting base 100 is fixed to the test sorting machine, wherein the mounting base 100 is fixed to the test sorting machine by screw locking, so that the installation and disassembly of the visual inspection structure and the test sorting machine can be facilitated, thereby improving the use effect.

[0043] The camera 200 is disposed on the mounting seat 100 to obtain image information of the chip 700 and feed the image information of the chip 700 back to the test sorting machine. The test sorting machine performs the next operation on the chip 700 according to the image information fed back by the camera 200 .

[0044] The detection area 300 is disposed on the mounting base 100 and has a first detection position 310 .

[0045] The optical path deflection device 400 is installed on the mounting base 100; when the chip 700 is located at the first detection position 310, the optical path deflection device 400 can transmit the image information of the four peripheral sides of the chip 700 to the camera 200, that is, when the chip 700 is located at the first detection position 310, the camera 200 takes a picture once. Under the action of the optical path deflection device 400, the camera 200 can obtain the image information of the four peripheral sides of the chip 700 by taking a picture once, and then the camera 200 feeds back the image information of the four peripheral sides to the test sorting machine, which can reduce the number of times the camera 200 takes pictures, so that the chip 700 stays for a shorter time during the detection process. When the test sorting machine is fully loaded, the working efficiency of the test sorting machine can be effectively improved, thereby solving the technical problems existing in the prior art.

[0046] The technical solution of the present invention adopts an optical path deflection device 400. When the chip 700 is located at the first detection position 310, the camera 200 takes a picture once. Under the action of the optical path deflection device 400, the camera 200 can obtain the image information of the four peripheral sides of the chip 700 by taking a picture once, and then the camera 200 feeds back the four peripheral side image information to the test sorting machine. In this way, the number of times the camera 200 takes pictures can be reduced, so that the chip 700 stays for a shorter time during the detection process. When the test sorting machine is fully loaded, the working efficiency of the test sorting machine can be effectively improved, thereby solving the technical problems existing in the prior art.

[0047] In one embodiment, the optical path redirecting device 400 includes a fiber optic lens (not shown), wherein the fiber optic lens includes a lens and a fiber optic bundle, wherein the lens is connected to one end of the fiber optic bundle, the fiber optic bundle is connected to the camera 200, and the image information is transmitted into the camera 200 through the fiber optic bundle. In this embodiment, the fiber optic lenses are arranged in four groups, so that through the four fiber optic lenses, the camera 200 can obtain the image information of the four peripheral sides of the chip 700 through one shooting, thereby reducing the number of shooting times of the camera 200, thereby avoiding a long detection time of the chip 700, and thus being able to solve the technical problems existing in the prior art.

[0048] In one embodiment, the fiber optic lens can also be set to five groups, and the five groups of fiber optic lenses correspond to the four peripheral sides and the bottom (back) of the chip 700 respectively. In this way, the camera 200 can obtain the five surfaces of the chip 700 at the same time through the fiber optic lens, which can further improve the use effect and accelerate work efficiency. When the visual detection structure of the present application is used in a test sorting machine, it can reduce the installation and laying of the visual detection structure and reduce the production cost of the test sorting machine.

[0049] In one embodiment, reference Figure 2 , Figure 3 The optical path redirecting device 400 can also adopt the following structure, so that the camera 200 can obtain the image information of the four peripheral sides of the chip 700 in one shot, wherein the optical path redirecting device 400 includes a first reflective member 410, wherein the first reflective member 410 is configured as four, and the four first reflective members 410 are arranged around the first detection position 310, and are used to reflect the image information of the four peripheral sides of the chip 700 to the shooting end of the camera 200. In this embodiment, the image information of the peripheral side of the chip 700 is reflected to the shooting end of the camera 200 by the first reflective member 410. Compared with the above-mentioned optical fiber bundle, the image information obtained by the camera 200 can be clearer, which is convenient for subsequent operations. In this embodiment, the camera 200 can be arranged below the first reflective member 410. In this embodiment, each of the first reflective members 410 is provided with a backlight source 450 and a light source diffusion plate 460 at one end away from the first detection position 310.

[0050] In one embodiment, reference Figure 4 , Figure 6 In order to further improve the function of the visual detection structure of the present application, the detection area 300 is also provided with a second detection position 320; when the chip 700 is located at the second detection position 320, the optical path deflection device 400 can transmit the image information of the bottom surface of the chip 700 to the camera 200. Under the action of the second detection position 320, the visual detection structure has the function of detecting five surfaces of the chip 700, namely the four peripheral sides and the bottom surface (back surface) of the chip 700. When the visual detection structure of the present application is applied to a test sorting machine, it can reduce the installation and laying of the visual detection structure and reduce the production cost of the test sorting machine.

[0051] In one embodiment, reference Figure 4 The four first reflecting components 410 are arranged around the second detecting position 320. In this way, the first detecting position 310 and the second detecting position 320 can be surrounded by the four first reflecting components 410, and the first detecting position 310 and the second detecting position 320 are closer to each other, which makes the structure of the detecting area 300 more compact and small, thereby making the structure of the visual detection structure of the present application more compact and occupies less space. When the structure is applied to a test sorting machine, it can occupy a smaller space of the test sorting machine, which is convenient for other equipment to be installed on the test sorting machine.

[0052] In this embodiment, reference Figure 4, the second detection position 320 and the first detection position 310 are distributed up and down, wherein the second detection position 320 is arranged below the first detection position 310, so that the structure of the detection area 300 can be made smaller, and the structure of the visual detection structure of the present application can be made more compact. In addition, since the camera 200 is arranged below the first reflective member 410, the second detection position 320 is arranged below the first detection position 310 to facilitate the camera 200 to obtain the image information of the bottom surface (back surface) of the chip 700 more clearly, and to avoid the situation where the image information of the bottom surface (back surface) of the chip 700 obtained by the camera 200 is not blurred due to the influence of the focal length.

[0053] In one embodiment, reference Figure 1 , Figure 5 The optical path redirecting device 400 also includes a second reflecting component 420, which is used to reflect the image information of the bottom surface of the chip 700 to the shooting end of the camera 200, or to reflect the image information of the peripheral side of the chip 700 reflected by the first reflecting component 410 to the shooting end of the camera 200. In this embodiment, the camera 200 can be set on one side of the second reflecting component 420. In this embodiment, the second component is set to reflect the light path for the second time, so that the installation position of the camera 200 can be more convenient. That is to say, the installation position of the camera 200 can be far away from the first reflecting component 410, so that the installation height of the first reflecting component 410 can be reduced, so that the height of the visual detection structure of the present application is reduced, which makes the structure of the test sorting machine using the visual detection structure of the present application more compact, and reduces the production cost of the equipment.

[0054] In one embodiment, reference Figure 5 The first reflecting component 410 and the second reflecting component 420 are both configured as prisms or plane mirrors. When the first reflecting component 410 and the second reflecting component 420 are both configured as plane mirrors, the plane mirrors have a certain angle when installed, so that reflection of image information can be achieved. In this embodiment, the installation angle of the plane mirror is 45°.

[0056] In one embodiment, reference Figure 1 , Figure 2The light path redirecting device 400 also includes a first box body 430 and a second box body 440; the first box body 430 is installed on the second mounting frame 500 for the installation of the first reflecting member 410, the backlight source 450, and the light source diffusion plate 460; the second box body 440 is installed on the second mounting frame 500 for the installation of the second reflecting member 420, wherein the first box body 430 and the second box body 440 are connected to the first mounting frame 600 by screw locking; this is to facilitate the installation and disassembly of the staff and to facilitate assembly, and at the same time, the structure can be modularized under the screw locking method, so that the damaged module can be replaced conveniently during use; in this embodiment, the first box body 430 and the second box body 440 are set to reduce light interference, so that the image information is clearer when reflected.

[0057] In one embodiment, reference Figure 1 The visual detection structure also includes a first mounting frame 600, which is used for mounting the camera 200. The first mounting frame 600 can be detachably mounted on the mounting base 100, wherein the first mounting frame 600 is connected to the mounting base 100 by screw locking, so as to facilitate the installation and disassembly of the camera 200 and facilitate the installation, disassembly and maintenance by the staff.
