[0029] It also includes a detection head 12, a marking pen 13, a detection light 14 and a moving part; the moving part is connected to the pressure plate 6; the moving part is connected to four detection heads 12 in a circular array, and the detection head 12 is a light-sensitive detector; each detection head 12 is fixedly connected to a marking pen 13; four detection lights 14 in a circular array are fixedly connected to the blister board 2, and each detection light 14 is located in a corresponding through hole 2a; the moving part is used to drive the detection head 12 and the marking pen 13 to move up and down.

[0030] The moving parts include a second connecting plate 9, a third hydraulic push rod 10 and a third connecting plate 11; the second connecting plate 9 is fixedly connected to the pressure plate 6; the third hydraulic push rod 10 is fixedly connected to the second connecting plate 9; the third connecting plate 11 is fixedly connected to the telescopic end of the third hydraulic push rod 10; the third connecting plate 11 is fixedly connected to all the detection heads 12.

[0031] A hemispherical structure is provided on the upper part of the detection lamp 14 for guiding stamping debris and burrs.

[0032] First, the staff installs the integrated blister punching and cutting device at the location where it needs to be used, and then uses the external connecting pipe to connect the external suction device with the exhaust pipe 15. It should be noted that due to mold problems, operation problems and temperature problems, bubbles exist locally in the blister after forming. When punching the blister, if there are bubbles at the punching of the blister, the strength around the hole will be greatly reduced. In addition, if there are bubbles, cracks are likely to occur around the hole during the punching process, affecting the quality of the blister;

[0033] Therefore, when the present integrated blister forming punching and cutting device is working, the blister sheet is first placed on the blister plate 2 through an external conveying device or a staff member, and then the first hydraulic push rod 5 is controlled to push the pressing plate 6 to move downward close to the blister sheet, that is, the pressing plate 6 drives the extrusion strip 6a to move downward to contact and limit the blister sheet, and then the external suction device is controlled to perform blister forming through the suction pipe 15 to form the blister piece. After the blister piece is formed, the detection lamp 14 is turned on, the light passes through the through hole 2a, and then the light passes through the blister piece on the blister plate 2. In this process, when the blister piece The presence of bubbles will affect the light transmission effect. The detection head 12 above determines whether there are pores at the punching position on the blister according to the transmitted light. That is, the bubbles on the blister are detected in the above manner. When bubbles are detected at the punching position, the third hydraulic push rod 10 is controlled to push the third connecting plate 11 to move downward. The third connecting plate 11 drives the detection head 12 to move downward. The detection head 12 drives the marker 13 to move downward to approach and contact the blister below to mark it, so that subsequent staff can quickly locate and detect whether the bubbles will affect the use of the blister. The subsequent staff will test the bubbles on the blister again to determine whether it can be put into use (it should be noted that if there are bubbles on the blister, whether it can be put into use depends mainly on the severity of the bubbles). Then the staff will rotate the blister on the blister plate 2 to avoid the bubbles on the blister being located at the punching position. After the adjustment, if there are no bubbles at the punching position, the first hydraulic push rod 5 will be controlled to further push the pressing plate 6 to move downward so that the pressing plate 6 fits the blister, and then the second hydraulic push rod 7 will be controlled to push the punch head 8 to move downward to perform the punching work. The residual pieces after punching enter the through hole 2a and then fall downward, and are guided to both sides under the action of the protective shell on the detection lamp 14, and fall into the waste frame of the external device below. The blister after punching is transferred by an external transfer device (manipulator, etc.). If there are still bubbles at the punching position after the blister is adjusted, the blister is transferred to an external recycling frame by an external transfer device (manipulator, etc.), and the blister is recycled as a raw material, that is, through the above method, the punching position is staggered with the bubbles on the blister to ensure the quality of the blister after punching.

[0037] When the bubbles on the blister are detected by the cooperation of the detection head 12 and the detection light 14, the first hydraulic push rod 5 first pushes the pressing plate 6 to move downward close to the blister, and the pressing plate 6 drives the rubber block 101 to move downward close to the blister, and the rubber block 101 moves downward close to and fits the blister, and the light emitted by the detection light 14 is covered by the rubber block 101 to prevent the light of the detection light 14 from being refracted through the bubbles to affect the adjacent detection head 12, causing the adjacent detection head 12 to be affected by the refracted light, thereby affecting the detection result;

[0038] When punching, the first hydraulic push rod 5 is controlled to further push the pressing plate 6 to move downward, so that the rubber block 101 is deformed and closely attached to the blister, thereby enhancing the fixing effect of the periphery of the blister to be punched during the punching process of the blister, which is beneficial to the punching operation of the blister, and the inner side surface of the rubber block 101 is set as an inclined surface inclined toward the outer side surface. When the rubber block 101 is deformed and closely attached to the blister, the rubber block 101 is deformed toward the outer side, thereby preventing the rubber block 101 from blocking the position of the blister to be punched.

[0044] The second limiting plate 204 is covered with a rubber sleeve to enhance the fixing effect.

[0045] After the external conveying equipment or the staff places the blister sheet on the blister plate 2, the electric push rod 202 is controlled to push the two first limit plates 203 to move toward each other, so that the blister sheet is fixed by the cooperation of the two first limit plates 203 and the second limit plate 204 to ensure the blister piece is formed.
