[0019] Reference Figure 1-4 The utility model provides a chip unsealing device, including a support frame 2, a workbench 1 is fixedly connected to the upper end of the support frame 2, a storage box 9 is fixedly connected to the upper end of the workbench 1, a steel plate 10 is fixedly connected to the interior of the storage box 9, a heating plate 17 is fixedly installed at the lower end of the steel plate 10, a second air extraction component is connected to the left side of the upper end of the workbench 1 through a third fixed frame 12, a blowing component is connected to the right side of the upper end of the workbench 1 through a first fixed frame 4, and the second air extraction component and the blowing component are respectively located at the left and right ends of the storage box 9, and the rear side of the upper end of the workbench 1 is connected to the first air extraction component through a second fixed frame 7. During operation, the chip to be unsealed is placed on the upper end of the steel plate 10, with the front side of the chip facing upwards. Then, the heating plate 17 is controlled to operate. The heat generated by the heating plate 17 is transferred to the chip through the steel plate 10, so that the temperature of the chip itself is increased. Then, a high-concentration concentrated nitric acid solution is taken and dripped on the upper end surface of the chip. At this time, the concentrated nitric acid liquid reacts with the polymer resin on the surface of the chip. During the reaction, bubbles will emerge and toxic gases will be generated. At this time, the blowing component is controlled to operate to blow the toxic gases generated by the chip during the unsealing process to the left. At the same time, the first exhaust component and the second exhaust component are operated. During component operation, the second vacuum component absorbs the toxic gas blown from right to left, and the first vacuum component absorbs the toxic gas floating upward, which can reduce the chance of gas dispersion. Since a large amount of toxic gas has been absorbed, the chance of staff inhaling toxic gas can be reduced. As the polymer resin on the surface of the chip reacts with the concentrated nitric acid solution, the internal structure of the chip can be gradually exposed. After the reaction is completed, the chip can be taken out and rinsed with isopropyl alcohol or anhydrous ethanol, and finally rinsed with deionized water to complete the chip unsealing work.

[0020] Furthermore, a notch 16 is provided on the upper end surface of the storage box 9. During operation, the notch 16 facilitates the staff to use tools to take out the chip from the storage box 9.

[0021] Further, the steel plate 10 gradually tilts downward from the front to the back. During operation, during the unsealing operation, the poured concentrated nitric acid solution is not easy to flow out of the storage box 9, thereby avoiding contamination of other positions.

[0022] Furthermore, the second air extraction assembly includes a second air collecting hood 11, a third connecting pipe 13, a second air pump 20 and a second exhaust pipe 15. The lower end of the workbench 1 is fixedly connected to the second air pump 20, the exhaust end of the second air pump 20 is fixedly connected to the second exhaust pipe 15, the air extraction end of the second air pump 20 is fixedly connected to the third connecting pipe 13, the third connecting pipe 13 passes through the third fixed frame 12 to the right and is fixedly connected to the third fixed frame 12, the right end of the third connecting pipe 13 is fixedly connected to the second air collecting hood 11, and the second air collecting hood 11 opens to the right. During operation, the operation of the second vacuum fan 20 can enable the second air collecting hood 11 to extract the toxic gases floating from right to left, and draw these toxic gases into the second vacuum fan 20 along the third connecting pipe 13, and finally discharge them from the second exhaust pipe 15. The second exhaust pipe 15 here can be connected to an extended pipe, and the extended pipe is connected to the outside world which is spacious and has good air circulation. At this time, the toxic gases discharged from the second exhaust pipe 15 can be directly discharged to the outside, which can prevent the toxic gases from harming the working workers, thereby protecting the workers.

[0023] Furthermore, the blowing assembly includes a micro fan 18, a first connecting pipe 3 and a wind nozzle 5. The lower end of the workbench 1 is fixedly connected with the micro fan 18, the exhaust end of the micro fan 18 is fixedly connected with the first connecting pipe 3, the connecting pipe is fixedly connected with the first fixing frame 4, the left end of the first connecting pipe 3 is fixedly connected with the wind nozzle 5, the wind nozzle 5 is connected with the first connecting pipe 3, and the wind nozzle 5 opens to the left. When working, the gas brought by the operation of the micro fan 18 is ejected from the wind nozzle 5 along the first connecting pipe 3, and the ejected gas blows the toxic gas from right to left, which helps the second gas collecting hood 11 to fully absorb these toxic gases.

[0024] Furthermore, the first exhaust assembly includes a first exhaust pipe 14, a first exhaust fan 19, a second connecting pipe 8 and a first air collecting hood 6. The lower end of the workbench 1 is fixedly connected to the first exhaust fan 19, the exhaust end of the first exhaust fan 19 is fixedly connected to the first exhaust pipe 14, the exhaust end of the first exhaust fan 19 is fixedly connected to the second connecting pipe 8, the second connecting pipe 8 passes through the second fixed frame 7 forward and is fixedly connected to the second fixed frame 7, the lower end of the second connecting pipe 8 is fixedly connected to the first air collecting hood 6, the first air collecting hood 6 is located directly above the storage box 9, and the first air collecting hood 6 is fixedly connected to the second fixed frame 7. During operation, the operation of the first vacuum fan 19 can enable the first air collecting hood 6 to extract the toxic gases floating from the bottom to the top, and let these toxic gases enter the first vacuum fan 19 along the second connecting pipe 8, and finally be discharged from the first exhaust pipe 14. The first exhaust pipe 14 here is connected to an external extended pipe, and the extended pipe is connected to the outside world with a spacious and air-permeable environment. At this time, the toxic gases discharged from the first exhaust pipe 14 can be directly discharged to the outside, which can prevent the toxic gases from harming the workers who are performing the opening operation, thereby protecting the workers.
