Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
The invention provides a punching device suitable for radioactive samples, which is arranged in a hot chamber, has a structure shown in figure 1, and comprises a punching part 1, a punch part 2, a sheet 3 (such as a steel sheet) to be punched, which is made of metal materials, a clamp 4, a cleaning mechanism 5, a storage box 6 and a monitoring camera 7. Wherein, the punching part 1 has a horizontal slit 11, see fig. 2, the horizontal slit 11 is provided with an upper punch hole 12 and a lower punch hole 13 which are opposite, the punch part 2 is arranged right above the upper punch hole 12, the sheet 3 to be punched is clamped by the clamp 4 to move in a horizontal plane, the sheet 3 to be punched passes through the horizontal slit 11, the punch punches the sheet 3 through the upper punch hole 12 and passes through the lower punch hole together with the punched sample, and after the sample is separated from the punch, the punch returns to the upper part of the punching part 1.
The thin sheet 3 to be punched is placed in a pneumatic clamp 4 by a manipulator in a hot chamber, the thin sheet is clamped in a pneumatic mode, the pneumatic clamp 4 can move in the x and y directions in the horizontal plane, the thin sheet is moved to the position between an upper punching hole 12 and a lower punching hole 13 by manually or automatically controlling the clamp to move, the punch part 2 is provided with an actuating device such as a pneumatic device, and the punching action in the Z direction vertical to the horizontal plane can be realized. When punching, the thin sheet 3 to be punched is clamped between the upper punch hole 12 and the lower punch hole 13 by the pneumatic clamp 4, the thin sheet is punched by manually or automatically controlling the punch head through the upper punch hole, and then the punch head and the punched wafer sample completely pass through the lower punch hole. Underneath the lower punch 13 is the sample receiver 6, where the wafer sample may have separated from the punch and fall into the receiver 6, or may adhere to the punch. And the cleaning mechanism 5 is arranged on one side below the punching part 1, the cleaning mechanism 5 comprises a rotatable brush, the brush is driven by a rotating mechanism, and the position of the brush head corresponds to the lower limit position of the movement of the punch.
