[0002] Common materials of the telescope prism light-shielding sheet include optical glass, quartz glass, thin metal foil (such as molybdenum sheet and stainless steel) and high-molecular thin film. In the shearing process of the existing automatic precision shearing equipment, many burrs are generated on the side of the shearing blade facing the workpiece to be processed. When the shearing blade shears the light-shielding sheet, the burrs or small waste materials scratch the surface of the light-shielding sheet, causing local thinning, micro-cracks or edge burrs, which directly affect the quality and use effect of the light-shielding sheet. Therefore, we need a telescope prism light-shielding sheet automatic precision shearing equipment to detect the burrs on the side of the shearing blade facing the workpiece to be processed and clean the burrs after detecting the existence of the burrs.

[0019] The initial state of the memory metal sheet is a contraction state, at this time, the cleaning block is not in contact with the shearing inner wall surface of the shearing cutter, when the cleaning mechanism works, the telescopic electric cylinder lowers the whole cleaning mechanism, in the process of lowering to the designated position, the external power supply supplies power to the memory metal sheet to heat the memory metal sheet, the memory metal sheet is deformed and elongated by the heat to push the cleaning block to the shearing inner wall surface of the shearing cutter until the cleaning spring is compressed by a certain distance; in the process of lowering the memory metal sheet and the cleaning block, the cleaning block cleans the inner wall of the shearing cutter, after cleaning, part of burrs may be left on the shearing surface of the shearing cutter and point to the light-shielding sheet, at this time, the memory metal sheet and the cleaning block continue to descend until the cleaning block penetrates through the shearing cutter, the cleaning spring is elongated to push the cleaning block to clean the burrs on the shearing surface of the shearing cutter and pointing to the light-shielding sheet, preventing the burrs left on the shearing surface of the shearing cutter and pointing to the light-shielding sheet from scratching the surface of the light-shielding sheet when the shearing equipment is shearing, causing local thinning, micro cracks or edge burrs, directly affecting the quality and use effect of the light-shielding sheet.

[0020] Further, all the electrode sheets and the positive electrode of the external power supply are connected in parallel.

[0021] When the burr cleaning module works, the external power supply supplies power to the shearing cutter and each electrode sheet at the same time, since the distance between the electrode sheet and the inner wall of the shearing cutter is very short, at this time, each electrode sheet, the external power supply and the shearing cutter form a single complete loop, if there are burrs between the electrode sheet and the shearing cutter under the power-on state that affect the shearing quality, the distance between the electrode sheet and the shearing cutter in the single loop is shorter or directly connected together due to the existence of the burrs, then the resistance in the single loop will be sharply reduced, the current will be increased, the console can monitor the change of the current and voltage on each loop, the console monitors this change to control the cleaning mechanism to start cleaning the detected burrs.

[0034] like Figure 5 As shown, the air guide block 5 has a cavity inside, and the cavity inside the air guide block 5 is connected to an external blower.

[0035] When the shearing module 3 is shearing, the external blower blows air into the cavity. The airflow flows into the shearing module 3 and blows onto the light-shielding sheet to compact it.

[0037] The output end of the driving cylinder 22 is extended to press down the shearing cutter 33. After the shearing cutter 33 contacts the sunshade, the shearing plate 31 slides, and the shearing spring 32 is compressed.

The other end of the fixed rod 43 is inserted into the air guide block 5 and the shearing cutter 33 in sequence. The other end of the fixed rod 43 is fixedly connected with the electrode plate 42. The other end of the fixed rod 43 is fixedly connected with one end of the cleaning mechanism 44. The electrode plate 42 is located below the cleaning mechanism 44.

[0041] When the burr cleaning module 4 cleans the shearing cutter 33, the output end of the telescopic cylinder 41 is extended to drive the cleaning mechanism 44 to clean the shearing inner wall surface of the shearing cutter 33 and the shearing blade surface of the shearing cutter 33 in sequence.
