In addition, the limiting vertical plate 64 is in contact with the upper end surface of the detection and screening platform 1 before moving up.

[0038] The lower end of the second connecting rod 65 is hinged with a bearing movable plate 7 , on which movable carrying bars 71 are symmetrically fixedly provided, and on which matching slide bars 72 are fixedly provided. The matching slide bars 72 are inserted into the matching slideways 131 .

[0039] A driving assembly includes an electric telescopic rod 141, on which a driving carrier plate 143 is fixedly mounted, on which a detector 2 is mounted, and on which a positioning matching block 144 is fixedly arranged, the positioning matching block 144 is inserted into a positioning matching hole 20, matching channels 145 are symmetrically provided on the driving carrier plate 143, and guide plug-in rods 146 are symmetrically fixedly arranged below the driving carrier plate 143, the guide plug-in rods 146 are inserted into guide matching holes 142, and a supporting bottom block 147 is fixedly arranged at the lower end of the guide plug-in rod 146, and the supporting bottom block 147 is provided with a movable socket 148 and a matching socket 149.

[0040] The guide plug-in rod 146 is sleeved with a counterweight movable block 8, a sliding through hole 81 is provided on the counterweight movable block 8, the guide plug-in rod 146 is inserted in the sliding through hole 81, and the counterweight movable block 8 is symmetrically fixed with a matching contact rod 82, the matching contact rod 82 is inserted in the matching plug hole 149, the counterweight movable block 8 is hinged with a third connecting rod 83, the lower end of the third connecting rod 83 is hinged with a movable slat 84, the movable slat 84 is fixedly provided with a matching limit rod 85, and the matching limit rod 85 is inserted into the movable socket 148, and a positioning top plate 86 is fixedly provided on the upper end of the movable slat 84, and a positioning sleeve 87 is fixedly provided on the positioning top plate 86. Before the detector 2 moves upward, the matching contact rod 82 is in contact with the limiting bottom plate 15. When the detector 2 moves upward, the matching movable block 82 remains stationary under the action of gravity, thereby reducing the distance between the supporting bottom block 147 and the matching movable block 82 until the matching contact rod 82 is separated from the limiting bottom plate 15.

[0041] When the wafer is inspected, it is placed on the carrying movable plate 7, and then the electric telescopic rod 141 is started to drive the driving carrier 143 to move upward. As the driving carrier 143 moves upward, the matching movable block 82 remains stationary under the action of gravity, thereby reducing the distance between the supporting bottom block 147 and the matching movable block 82 until the matching contact rod 82 is separated from the limiting bottom plate 15. Under the action of the third connecting rod 83, the movable plate 84 is pushed to move. As the movable plate 84 moves, the positioning sleeve 87 is driven to move, so that the positioning sleeve 87 is sleeved on the positioning column 21 on the detector 2, thereby realizing the fixation of the detector 2, ensuring its stability during the movement, and also ensuring the stability of the detector 2 during the operation. When the detector 2 is in a non-working state, the positioning sleeve 87 is not sleeved on the positioning column 21, so that the detector 2 is in an unlocked state, which is convenient for its installation and removal, and further convenient for the inspection and maintenance of the detector 2. In addition, as the electric telescopic rod 141 is extended, the rotating wheel 23 on the detector 2 will contact the inclined matching strip 31, so that the linkage carrier 3 will be pushed to move under the action of the rotating wheel 23. As the linkage carrier 3 moves, the matching connecting column 43 will be pulled downward under the action of the pull-down frame 35, thereby driving the movable bearing rod 4 to move downward. As the movable bearing rod 4 moves downward, the movable installation rod 5 will be driven to move under the action of the first connecting rod 44, so that the arc clamping plate 51 will contact the side of the wafer, pushing The movable wafer is moved in a small range to clamp and position the wafer, so that the pins on the chip are aligned with the detection contact points 25 on the detector 2 up and down. After the arc clamp 51 clamps the wafer, as the detector 2 continues to move upward, the supporting plate 22 will contact the lower end surface of the movable ring body 6, so that the movable ring body 6 will be pushed upward by the action of the supporting plate 22, and the upward movement of the movable ring body 6 will drive the connecting top plate 63 to move upward, so that under the action of the second connecting rod 65, the supporting movable plate 7 will be pulled to move, so that it will move away from the bottom of the wafer and no longer contact the wafer. In this way, as the detector 2 moves upward, the detection contact point 25 will contact the pins of the chip, thereby realizing the detection of the wafer and screening out the problematic chip marks. After the detection is completed, the electric telescopic rod 141 is started to retract downward, driving the detector 2 to move downward. As the detector 2 moves downward, the movable ring body 6 will move downward under the action of its own gravity and the second spring 621. In this way, under the action of the second connecting rod 65, the supporting movable plate 7 will be driven to move in the opposite direction and reset, so that it is supported under the wafer again. As the detector 2 moves further downward, the linkage carrier plate 3 will be reset under the action of the first spring 33. In this way, the movable bearing rod 4 can be driven to move upward under the action of the pull-down frame 35. As the movable bearing rod 4 moves upward, the movable mounting rod 5 will be driven to move in the opposite direction and reset under the action of the first connecting rod 44. In this way, the circular arc clamp 51 can release the wafer, making it convenient to remove the wafer.In the next step, in addition, when the driving carrier 143 moves downward, the contact rod 82 contacts the limit bottom plate 15, so that the counterweight movable block 8 no longer moves downward under the restriction of the limit bottom plate 15. As the support bottom block 147 moves downward, the distance between the counterweight movable block 8 and the support bottom block 147 increases. In this way, the movable plate 84 moves under the action of the third connecting rod 83, so that the positioning sleeve 87 is no longer sleeved on the positioning column 21, and the detector 2 is unlocked. The operation is simple, convenient and fast.
