[0020] like Figure 1-Figure 4 As shown, a single chip product carrier positioning detection device, the single chip product carrier is Boat, and the detection device uses Boat inspection tool 1; Figure 1-Figure 2 As shown, the boat inspection fixture 1 is a rectangular plate, baffles 7 are vertically arranged on both sides of the rectangular plate, and notches are arranged in the middle of the baffles 7 on both sides, and the notches are used to take the boat to facilitate manual operation.

[0021] like Figure 3-Figure 4 As shown, a single Boat pin 5 includes eight pins 6 that are evenly distributed; 5 rows and 10 columns of single Boat pins 5 are arranged on each Boat, and a single Boat 4 is tested each time.

[0022] The pin positioning holes 8 corresponding to the single Boat pin 5 and matched with the single Boat pin 5 are evenly arranged in 5 rows and 10 columns on the corresponding single Boat 4 of the Boat inspection fixture 1 .

[0023] A correction block 2 for vertically limiting the single-piece Boat 4 is installed on the upper end surface and the notch position of one side of the Boat inspection fixture 1; the inspection device also includes a correction block base 3, two springs 101 and two correction guide columns 102;

[0024] The correction block base 3 is arranged at a notch on one side of the upper end surface of the Boat gauge 1, and the correction block base 3 is horizontally provided with two first through holes, and the correction block 2 is provided with two second through holes corresponding to the first through holes of the correction block base 3, one end of the correction guide column 102 is arranged in the corresponding first through hole, and the other end of the correction guide column 102 is arranged in the corresponding second through hole of the correction block 2, and the corresponding spring 101 is sleeved on the correction guide column 102, one end of the spring 101 is installed on the correction guide column 102, and the other end is installed on the correction block 2. In the initial state, the gap distance between the correcting block 2 and the side baffle 7 away from the correcting block 2 is smaller than the length of the single-piece Boat 4. At this time, the spring 101 is in the original state neither stretched nor compressed. When the single-piece Boat 4 needs to be detected, the correcting block 2 is pulled outward, the spring 101 is compressed, and one side wall of the single-piece Boat 4 is placed vertically downward against the side baffle 7 away from the correcting block 2, and then the correcting block 2 is released, the spring 101 is reset, and the other side wall of the single-piece Boat 4 is against the correcting block 2, ensuring that the single-piece Boat 4 is in a vertical downward state during the downward detection process.

[0025] A corresponding detection device for detecting the verticality of a single boat pin 5 is provided on the upper end surface of the boat inspection fixture 1, near the notch. The detection device uses a proximity sensor 100; one end of the proximity sensor 100 is installed at the inner side of the corresponding baffle 7, and the other end extends out of the boat inspection fixture 1. The proximity sensor 100 is contact-type. When each single boat pin 5 on a single-chip Boat 4 is fully inserted into the corresponding pin positioning hole 8, both ends of one end surface of the single-chip Boat 4 can touch the corresponding proximity sensor, and the proximity sensor is triggered to be qualified.

[0026] like Figure 1-Figure 4 As shown, the working principle and process of the utility model are as follows:

[0027] Place the single piece of Boat 4 vertically downward into the Boat fixture 1, and manually push the alignment block 2 to move to the right ( Figure 2Perspective), the spring 101 is compressed, and an air gap greater than the length of a Boat is left between the correction block 2 and the side baffle 7 away from the correction block 2. One side wall of the Boat is against the side baffle 7 away from the correction block 2. After the correction block 2 is released, the spring 101 is reset and the correction block 2 is against the other side wall of the Boat to limit the Boat, ensuring that the Boat is in a vertical downward state. Each single Boat pin 5 is compared with the corresponding pin positioning hole 8. When all the pin pins 6 on the single-chip Boat4 can be completely inserted into the corresponding pin positioning hole 8 vertically downward, and can be inserted smoothly without jamming, it means that there is no deformation. At this time, both ends of one end face of the single-chip Boat4 can touch the proximity sensor, and the proximity sensor transmits a signal to the external controller, and the external controller transmits a signal to the external computer, which means that the single Boat pin 5 on the Boat has no deformation and can overlap with the Boat inspection fixture 1, and the proximity sensor is triggered to be qualified.
