[0033] The test sorting machine is a type of chip processing equipment with functions such as testing and sorting. Its testing functions include but are not limited to resistance detection and voltage detection of chips. In order to enable the test sorting machine to test different types of chips. During testing, corresponding test sockets are usually selected for different types of chips to cooperate with the chips for testing, and the number of chips of the same type is relatively large during testing. After the test socket is installed in the test sorting machine, it is necessary to calibrate the test position on the test socket to correspond to the position of the suction nozzle, so that when the suction nozzle places the chip on the test socket, the chip can be accurately located in the test position in the test socket. However, during the installation process, the existing test socket is inconvenient when aligning with the suction nozzle, which makes the test socket installation process more cumbersome. At the same time, the structure of the test socket during alignment adjustment is more complicated, resulting in a higher cost for the test sorting machine.

[0034] The utility model proposes a position detection structure, referring to Figure 2 , Figure 3 , used for testing the sorting machine 500, wherein the testing sorting machine 500 includes a frame (not shown), a suction nozzle 510, a stepping member 520, a turret (not shown), etc., wherein the stepping member 520 can be a stepping voice coil motor, or a stepping cylinder, etc., which is not limited here. When the stepping voice coil motor is selected, it can better control the stepping stroke of the suction nozzle 510, and at the same time can reduce the vibration amplitude of the suction nozzle 510 when it is active.

[0035] See also Figure 1 In one embodiment of the present utility model, the position detection structure includes:

[0036] The mounting seat 100 is provided with a mounting position 110, wherein the mounting position 110 is used for installing a test seat, one of the test seats is used for testing the same type of chip, and the test seat is detachably mounted on the mounting position 110. When the type of chip is changed, the corresponding side test seat needs to be replaced.

[0037] The marking member 200 is detachable from the installation position 110 , and the marking member 200 is used to be pressed by the suction nozzle 510 ; when the suction nozzle 510 presses the marking member 200 , the marking member 200 obtains the mark of the suction nozzle 510 .

[0038] The visual component 300 includes a camera 310 and an optical path redirecting device 320. The optical path redirecting device 320 is used to transmit the image information of the mark to the camera 310, wherein the camera 310 obtains the image information and then feeds the image information back to the display device (not shown). The camera 310 and the display device can be connected by wire or by wireless connection (Bluetooth, etc.). The display device can be a display device on the test sorting machine 500, or other display structures, such as a tablet, a mobile phone, etc. The image information is used for reference when the test seat is installed in the installation position 110, so that the test position of the test seat corresponds to the suction nozzle 510. In this embodiment, specifically during use, the turret drives the suction nozzle 510 to rotate to the top of the marking member 200, and then the lower pedal 520 drives the suction nozzle 510 to move toward the marking member 200, so that the suction nozzle 510 presses the marking member 200. After the suction nozzle 510 presses the marking member 200, the marking member 200 obtains the mark of the suction nozzle 510, and then the lower pedal 520 drives the suction nozzle 510 to leave the marking member 200. At this time, the turret drives the suction nozzle 510 to rotate a preset angle to expose the mark, wherein the preset angle is 7.5 degrees. In other embodiments, the preset angle can also be 9 degrees, 10 degrees, etc. At this time, the camera 310 obtains the image information of the mark of the suction nozzle 510 on the marking member 200 through the optical path deflection device 320. Since the suction nozzle 510 rotates 7.5 degrees, the camera 310 will not be disturbed by the suction nozzle 510 when obtaining the image information of the mark. After the camera 310 obtains the image information of the mark, it will be fed back to the display device. Then the staff can remove the marking member 200 from the mounting seat 100, and then install the test seat on the mounting position 110 on the mounting seat 100. During the installation process, the image information of the mark can be used as a position reference to make the test position of the test seat correspond to the suction nozzle 510, wherein the outline of the suction nozzle 510 can be used as a reference when the test seat is installed. In other embodiments, the center position of the suction nozzle 510 can also be used as a reference, or a cross line can be drawn according to the center position of its mark, and the test seat can also be referenced according to the cross line during the installation process. After the test position on the test seat corresponds to the image information of the mark, the test seat can be fixed on the mounting position 110. When the test seat is located at the installation position 110, the camera 310 can obtain image information of the test seat through the optical path redirecting device 320. At this time, the image information of the test seat is compared with the image information of the mark to achieve the alignment of the test seat and the suction nozzle 510. The operation is simple and convenient; thereby solving the problem in the prior art that it is inconvenient to align the test seat with the suction nozzle 510 during the installation process.At the same time, in this embodiment, the marking member 200 and the test seat share a mounting position 110, which can improve the performance of the mounting seat 100 in the position detection structure of the present application, while reducing the setting of the mounting position 110, reducing the production cost of the mounting seat 100, and thereby reducing the manufacturing cost of the test sorting machine 500.

[0039] The technical solution of the present invention adopts a marking part 200 and a visual component 300. The suction nozzle 510 is marked in advance by the marking part 200. At this time, the marking part 200 can obtain the position of the suction nozzle 510 relative to the installation position 110, and then the camera 310 obtains the image information of the mark of the suction nozzle 510 on the marking part 200 through the optical path deflection device 320. Then the marking part 200 is removed from the mounting seat 100, and then the test seat is installed on the mounting position 110. At this time, the camera 310 can obtain the image information of the test seat through the optical path deflection device 320. By comparing the two image information, the center of the test position in the test seat corresponds to the center of the suction nozzle 510, and then the test seat is fixed on the mounting position 110. It is simple and convenient to operate, and it is relatively convenient to align with the suction nozzle 510, thereby being able to solve the technical problems existing in the prior art.
