[0039] The use process of the chip supporting device for chip detection is as follows:

[0040] When the chip needs to be detected, first, the driving motor matched and arranged outside the protective shell 2 is started, the driving motor drives the threaded sleeve (not shown in the figure) to rotate through the worm (not shown in the figure) and the worm wheel (not shown in the figure) matched and arranged inside the protective shell 2, and finally the chip placing plate 4 is pushed upward to move.

[0041] In addition, when the chip placing plate 4 drives the two limiting plates 5 to ascend synchronously, the limiting plates 5 drive the first fixed rods 11 and the first sliding rods 12 to move, so that the first sliding rods 12 gradually move from the inside of the first inclined grooves 7 to the inside of the second inclined grooves 8, and the rolling shafts 13 move from the inside of the first guide inclined grooves 9 to the inside of the second guide inclined grooves 10, since the first guide inclined grooves 9 and the second guide inclined grooves 10 are both inclinedly arranged, the two limiting plates 5 are forced to move away from each other in the process of moving along the guide inclined grooves, thereby providing space for placing the chip.

[0042] When the chip placing plate 4 ascends to the highest position, the staff places the chip to be detected on the upper side of the chip placing plate 4, and then controls the driving motor to rotate reversely, thereby driving the chip placing plate 4 to descend, in the process of descending, the first sliding rods 12 gradually move back from the inside of the second inclined grooves 8 to the inside of the first inclined grooves 7, and the rolling shafts 13 move back from the second guide inclined grooves 10 to the first guide inclined grooves 9, at this time, under the action of the guide inclined grooves, the two limiting plates 5 move close to each other, thereby clamping and limiting the chip from both sides, so that the chip can be kept stable in the process of detection, when the chip placing plate 4 descends to the initial position, the limiting plates 5 complete the clamping and fixing of the chip, and then the chip detection can be started.

[0043] In the whole process, through the cooperation of the through groove 17, the vertical groove 18, the sliding block 19, the second fixed rod 14 and the second sliding rod 15 and the like, the stability of the limiting plates 5 in the process of ascending and descending and moving is ensured, and the overturning or deviation is avoided.

[0044] Meanwhile, if different specifications of chips need to be adapted, the staff can rotate the adjusting screw rod 16, drive the second fixed rod 14 to slide in the second sliding rod 15, thereby adjusting the initial position of the limiting plates 5, and improve the adjusting precision in combination with the scale mark 22.
