The side wall of the body 1 is fixedly connected with a support plate 112, which is arranged corresponding to the discharge port 111. The inner wall of the body 1 is provided with a detection mechanism 114. When working, the chip is placed in the material box 113, and then the material box 113 is placed on the support plate 112, and then the second cylinder 16 is started to contract to drive the storage plate 17 to descend, and then the material box 113 is pushed from the discharge port 111 into the first storage groove 15, and the material box 113 is placed on the top of the storage plate 17, and then the second cylinder 16 is started to stretch to drive the storage plate 17 and the material box 113 to rise, so that the material box 113 enters the internal detection area of ​​the body 1, and then the first cylinder 16 is started to stretch to drive the storage plate 17 and the material box 113 to rise, so that the material box 113 enters the internal detection area of ​​the body 1, and then the first cylinder 16 is started. The linear motor 11 moves horizontally and the first cylinder 13 moves longitudinally, driving the first cylinder 13 and the suction cup 14 to move above the material box 113, and then starting the first cylinder 13 to drive the suction cup 14 to suck up the chip in the material box 113, and then the first cylinder 13 drives the suction cup 14 to shrink, and then the first linear motor 11 and the first cylinder 13 cooperate to drive the first cylinder 13 and the suction cup 14 to move above the detection mechanism 114, and then the first cylinder 13 drives the suction cup 14 to stretch, put the chip in the detection mechanism 114 to start detection, and after the detection is completed, the suction cup 14 sucks the chip from the detection mechanism 114, cooperates with the first linear motor 11 and the second linear motor 12 to put it back into the material box 113 again, and then sucks the next group for detection.

When the material box 113 is level with the push plate 110, the second cylinder 16 is stopped. Then the third cylinder 19 is started to stretch and drive the push plate 110 to push the material box 113 out of the discharge port 111 and place it on the support plate 112. Then another material box 113 with the chips to be inspected is placed. The batch inspection of the chips is completed in this cycle. Through the above structure, the second cylinder 16 is connected to the placement plate 17, and the third cylinder 19 cooperates with the push plate 110 and the material box 113 to facilitate loading and unloading of chips, thereby reducing the need to open the hatch to fill chips, which may cause injuries to operators and a more cumbersome replacement process.

[0020] like Figure 2 and Figure 3 As shown, the inner wall of the machine body 1 is fixedly connected with a slide rail 2, and the slide rail 2 is arranged near the top of the first storage groove 15. The end of the slide rail 2 is fixedly connected with a motor body 21, and the output end of the motor body 21 is fixedly connected with a bidirectional screw 22. The middle part of the bidirectional screw 22 is threadedly connected with a pair of sliders 23, and the side wall of the slider 23 is fixedly connected with a clamping plate 24. The clamping plate 24 is arranged corresponding to the material box 113. When working, when the second cylinder 16 drives the storage plate 17 and the material box 113 to enter the machine body 1, the motor body 21 is started to drive the bidirectional screw 22 to rotate, and at this time, the bidirectional screw 22 will drive the slider 23 to the opposite direction. When the motor body 21 rotates forward, it will drive the slider 23 to contact both sides of the material box 113. At this time, the material box 113 can be clamped and fixed from both sides. When the material box 113 needs to be replaced, the motor body 21 rotates in the opposite direction to drive the slider 23 away from the material box 113 to release the fixation. Through the above structure, the motor body 21, the bidirectional screw 22 and the slider 23 are set, and the material box 113 can be clamped and fixed to improve the stability of the position of the material box 113 in the machine body 1, so as to reduce the situation where the detection mechanism 114 cannot absorb the chip due to position movement.

[0021] like Figure 5 As shown, a ventilation groove 3 is provided in the middle of the body 1, and a plurality of ventilation holes 31 are provided at the bottom of the inner side wall of the body 1, the ventilation holes 31 are connected with the ventilation groove 3, and the ventilation groove 3 and the detection mechanism 114 are arranged correspondingly, and an air pump 32 is fixedly connected to the side wall of the body 1, and the air pump 32 is connected with the ventilation groove 3. When working, the air pump 32 is started to drive the air flow into the ventilation groove 3 from the ventilation hole 31, and then flows into the air pump 32 for discharge. When the air flow flows from the ventilation hole 31, it will pass through the detection mechanism 114 above, and the detection mechanism 114 can be cooled at this time. Through the above structure, the ventilation groove 3, the ventilation holes 31 and the air pump 32 are arranged, and the detection mechanism 114 can be cooled when the chip is detected, so as to reduce the situation where the heat at the detection mechanism 114 is too large and causes chip damage.

[0022] like Figure 4 As shown, a plurality of slide grooves 4 are provided on the top of the support plate 112, and rollers 41 are rotatably connected in the slide grooves 4. During operation, when the push plate 110 pushes the material box 113 out of the discharge port 111, the bottom of the material box 113 will contact the rollers 41 on the surface of the support plate 112. At this time, the rollers 41 will rotate along with the movement of the material box 113. Through the above structure, the slide grooves 4 and the rollers 41 are set, and the rotation effect of the rollers 41 can be used to reduce the friction between the material box 113 and the support plate 112, thereby reducing damage caused by wear.

[0023] like Figure 4As shown, a baffle 5 is fixedly connected to the side wall of the support plate 112, and the baffle 5 is arranged to surround the support plate 112. During operation, when the material box 113 is pushed out, it will be on the surface of the support plate 112. When the material box 113 is close to the edge of the support plate 112, it will be blocked inside by the baffle 5. Through the above structure, the baffle 5 is arranged to connect the support plate 112, which can protect the material box 113 and reduce the sliding of the material box 113, resulting in the detachment from the support plate 112 and falling, which will cause the chips to scatter and be damaged due to impact.

[0024] like Figure 4 As shown, a push rod 6 is slidably connected to the middle of the baffle 5, and a top plate 61 is fixedly connected to the end of the push rod 6. During operation, when another group of material boxes 113 to be detected are placed on the surface of the placement plate 17, the material box 113 can be placed on the surface of the support plate 112, and then the push rod 6 is pushed to drive the top plate 61 to push the material box 113 into the surface of the placement plate 17. Through the above structure, the push rod 6 and the top plate 61 are set, which can facilitate the placement of the material box 113 on the surface of the placement plate 17, so as to improve the convenience of loading during use.

[0025] like Figure 4 As shown, the side wall of the top plate 61 is fixedly connected with an anti-collision pad 7, and the anti-collision pad 7 is arranged toward the side of the body 1. During operation, when the material box 113 is pushed out, when the material box 113 contacts the top plate 61, it will contact the anti-collision pad 7 on the surface of the top plate 61. Through the above structure, the anti-collision pad 7 can reduce the wear caused by the impact between the material box 113 and the top plate 61, and play a buffering and protective role.

[0026] Working principle: put the chip in the material box 113, and then put the material box 113 on the support plate 112, and then start the second cylinder 16 to contract and drive the placement plate 17 to descend, and then push the material box 113 from the discharge port 111 into the first placement slot 15, and place the material box 113 on the top of the placement plate 17, and then start the second cylinder 16 to stretch and drive the placement plate 17 and the material box 113 to rise, so that the material box 113 enters the internal detection area of ​​the machine body 1, and then start the first linear motor 11 to move horizontally and the first cylinder 13 to move longitudinally, drive the first cylinder 13 and the suction cup 14 to move to the top of the material box 113, and then start the first cylinder 13 to drive the suction cup 14 to suck up the chip in the material box 113, and then start the first cylinder 13 The suction cup 14 is driven to contract, and then the first linear motor 11 and the first cylinder 13 are cooperated to drive the first cylinder 13 and the suction cup 14 to move above the detection mechanism 114, and then the first cylinder 13 drives the suction cup 14 to stretch, and the chip is placed in the detection mechanism 114 to start detection. After the detection is completed, the suction cup 14 sucks the chip from the detection mechanism 114, and cooperates with the first linear motor 11 and the second linear motor 12 to put it back into the material box 113 again, and then sucks the next group for detection. When all the chips in the material box 113 are detected, the second cylinder 16 is started to contract to drive the placement plate 17 and the material box 113 to descend. When the material box 113 is level with the push plate 110, the second cylinder 16 is stopped, and then the third cylinder 19 is started to pull The push plate 110 is extended to push the material box 113 out of the discharge port 111 and place it on the support plate 112, and then another material box 113 for placing the chip to be tested is placed, and the batch detection of the chips is completed in this cycle. After the second cylinder 16 drives the placement plate 17 and the material box 113 to enter the machine body 1, the motor body 21 is started to drive the bidirectional screw 22 to rotate. At this time, the bidirectional screw 22 will drive the slider 23 to move in opposite directions. When the motor body 21 rotates forward, it will drive the slider 23 to contact both sides of the material box 113. At this time, the material box 113 can be clamped and fixed from both sides. When the material box 113 needs to be replaced, the motor body 21 is rotated in the opposite direction to drive the slider 23 away from the material box 113 to release the fixation, and the air pump 32 is started to drive The airflow enters the air permeable groove 3 from the air vent 31, and then flows into the air pump 32 for discharge. When the airflow flows from the air vent 31, it will pass through the detection mechanism 114 above, and the detection mechanism 114 can be cooled at this time. When the push plate 110 pushes the material box 113 out of the discharge port 111, the bottom of the material box 113 will contact the roller 41 on the surface of the support plate 112. At this time, the roller 41 will rotate with the movement of the material box 113. When the material box 113 is pushed out, it will be on the surface of the support plate 112. When the material box 113 is close to the edge of the support plate 112, it will be blocked inside by the baffle 5. When another group of material boxes 113 to be detected are placed on the surface of the placement plate 17, the material box 113 can be placed on the surface of the support plate 112.Then, the push rod 6 drives the top plate 61 to push the material box 113 into the surface of the storage plate 17. When the material box 113 is pushed out, when the material box 113 contacts the top plate 61, it contacts the anti-collision pad 7 on the surface of the top plate 61.
