Detailed Implementation

[0025] The present invention will be further described in detail below with reference to embodiments:

[0026] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0027] like Figs. 1 to 7 As shown, a testing device for memory chip production includes a support cylinder 1 and a cover plate 2 covering the upper surface of the support cylinder 1. A support tube 3 is rotatably installed on the inner bottom wall of the support cylinder 1, and the other side of the support tube 3 is fixedly connected to the bottom surface of the cover plate 2. A support column 4 is fixedly connected to the inner bottom wall of the support cylinder 1, and the other end of the support column 4 passes through the cover plate 2 and is fixedly connected to a mounting plate 5. A testing device 6 and a blower mechanism are installed on the mounting plate 5. Three placement cylinders 7 arranged in a circumferential array are fixedly connected inside the cover plate 2. Each placement cylinder 7 has multiple slots inside. The 6 can take pictures and test the chips. By opening the slots, it is not only convenient to pick up and put down the chips inside the placement cylinders 7, but also the dust on the chips can be discharged from the slots when blowing air. The areas corresponding to the three placement cylinders 7 are the loading and unloading area, the dust removal area, and the testing area, respectively. The corresponding operation can be performed when the placement cylinder 7 is rotated to the corresponding area.

[0028] The blower mechanism includes a second motor mounted on the upper surface of the mounting plate. The output end of the second motor is fixedly connected to a second drive shaft, and the other end of the second drive shaft passes through the mounting plate. Fan blades are mounted on the outer surface of the portion of the second drive shaft located below the mounting plate. When the second motor 19 is started, the second motor 19 can drive the fan blades 21 to rotate. The rotation of the fan blades 21 can blow away the dust on the chip below.

[0029] Each placement cylinder 7 is equipped with a placement mechanism, which includes a placement plate 13 slidably connected inside the placement cylinder 7. The upper surface of the placement plate 13 is provided with an anti-slip pad 14. The bottom surface of the placement plate 13 is fixedly connected with a spring 12 and a push rod 15. The other end of the spring 12 is fixedly connected to the inner bottom wall of the placement cylinder 7. The other end of the push rod 15 slides through the placement cylinder 7. The anti-slip pad 14 can effectively prevent the chip from sliding during rotation. When the spring 12 is in the normal state, the chip is located inside the placement cylinder 7.

[0030] The support cylinder 1 is equipped with a lifting mechanism corresponding to the placement mechanism. The lifting mechanism includes a support ring 16 fixedly connected inside the support cylinder 1. The support ring 16 has a track groove 17 for sliding the push rod 15. A top ring 18 is fixedly connected inside the track groove 17. The end of the push rod 15 away from the placement cylinder 7 is pressed against the top ring 18. The upper surface of the top ring 18 is a slope. When the placement cylinder 7 drives the push rod 15 to rotate to the detection area, that is, the highest point of the slope, the top ring 18 can lift the push rod 15 and the placement plate 13. At this time, the chip on the placement plate 13 will be moved out of the placement cylinder 7, and then the detection device 6 can detect the chip. After taking photos for inspection, when the cover plate 2 and the placement cylinder 7 continue to rotate, the top rod 15 and the placement plate 13 will gradually move down under the action of the spring 12. When the placement cylinder 7 rotates to the loading and unloading area, the operator can remove the inspected chip, replace it with a new chip, and then continue to drive the placement cylinder 7 to rotate. During the continued rotation, the top rod 15 and the placement plate 13 will not move up and down. When the placement cylinder 7 rotates to the dust removal area, the dust on the chip can be blown away by the blower. After continuing to rotate, the placement cylinder 7 and the top rod 15 will rotate to the inspection area again for inspection. At the same time as inspection, loading and unloading and blowing can be performed.

[0031] The support cylinder 1 is equipped with a drive mechanism for driving the support tube 3 to rotate. The drive mechanism includes a first motor 8 installed on the bottom wall of the support cylinder 1. The output end of the first motor 8 is fixedly connected to a first drive shaft 9. A gear 10 is fixedly connected to the outer surface of the first drive shaft 9. A gear ring 11 is fixedly connected inside the support tube 3, and the gear ring 11 meshes with the gear 10. When the first motor 8 is started, the first motor 8 can drive the first drive shaft 9 and the gear 10 to rotate. The rotation of the gear 10 can drive the gear ring 11, the cover plate 2 and the placement cylinder 7 to rotate.

[0032] When the cover plate 2 rotates to align the placement cylinder 7 with the loading and unloading area, the push rod 15 is at the lowest point of the slope of the top ring 18, and the placement plate 13 is at its lowest position under the action of the spring 12. At this time, the operator can gently place the chip on the anti-slip pad 14, and then control the cover plate 2 to rotate 120 degrees clockwise to enter the dust removal area. At this time, the push rod 15 moves along the gentle slope of the top ring 18, and the placement plate 13 remains stationary. Then, the fan blade 21 is driven to rotate by the second motor 19 to generate a downward airflow, which blows away the dust on the chip surface. The cover plate 2 continues to rotate 120 degrees to the detection area, and the push rod 15 moves to the detection area. When the top ring 18 reaches the highest point of the slope, it pushes the placement plate 13 and the chip upward, so that the chip is above the placement cylinder 7. Then the detection device 6 can take pictures of the chip for inspection. The image is analyzed for defects by the image processing algorithm. After the inspection is completed, the cover plate 2 rotates 120 degrees again to return to the loading and unloading area. The top rod 15 descends with the slope, and the spring 12 resets, causing the placement plate 13 to fall back. The operator takes away the inspected chip and puts in a new chip, completing one inspection cycle. The three-station parallel design can greatly shorten the inspection cycle of a single chip, thereby improving the overall inspection efficiency of the chip.

[0033] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
