When the side blasting guns 41 are swung, the side blasting guns 41 are swung in the thickness direction of the target material 12.
During use of the target 12, since projections such as burrs on the corners of the target 12 form arcs, it is required to sand blast the sides and non-sputtered areas of the target 12 to ensure removal of the projections caused by the burrs and machining marks. The conventional blasting process for the target material 12 is mainly performed manually due to the irregularity of the shape and direction of the blasting area. The roughness deviation of the sand blasting surface is large due to the uneven moving speed of the sand blasting in the manual sand blasting, and the deviation of the roughness measurement results of different positions reaches Ra2.0 mu m. The manual sand blasting operation efficiency is low, and the sand blasting is performed on the surface of the TFT target material 12 for 20 minutes per sheet. The manual sand blasting operation is high in danger, and even if protective tools are worn during manual operation, sand particles sprayed under high pressure are still at risk of being injured.
The automatic sand blasting equipment effectively improves the operation safety of workers by carrying out sand blasting on the plane target in the sand blasting chamber 11. The conveying speed of the conveying device 54 to the plane target is adjusted, so that the sand blasting speed of the sand blasting device to the plane target is controlled, the deviation of the roughness of the sand blasting surface of the plane target is reduced, and the sand blasting effect is more uniform. By arranging the middle sand blasting gun 21 and the side sand blasting guns 41 in the sand blasting chamber 11, the side surfaces 13 of the planar target and the sand blasting surfaces of the non-sputtering areas are correspondingly sand blasted by the sand blasting guns, so that the sand blasting surfaces of the planar target are comprehensively covered. Through the cooperation of the conveying device 54 and the sand blasting device, the automatic sand blasting of the plane target is realized, the sand blasting operation efficiency of the plane target is improved, and the guidance of the sand blasting operation is improved.
Specifically, before the blasting, the blasting pressure of each of the side blasting guns 41 and the middle blasting gun 21 is set according to the blasting requirement of the flat target, the swing amplitude, the swing speed, the blasting time of the side blasting guns 41 and the middle blasting gun 21 and the conveying speed of the conveying device 54 are set in a matching manner, the flat target is placed on the conveying device 54, a blasting inlet of the target material 12 is arranged between the blasting chamber 11 and the conveying device 54, the conveying device 54 moves the flat target into the blasting chamber 11 through the blasting inlet of the target material 12 for blasting, and the flat target is conveyed and moved out through the conveying device 54 after the blasting.

The swing driving device drives the middle swing rod 23 to rotate in a reciprocating mode, the middle sand-blasting gun 21 is fixed to the middle swing rod 23, and therefore the middle swing rod 23 drives the middle sand-blasting gun 21 to swing in a reciprocating mode. Because the sandblast area of the 12 faces of the target is large, the middle part sandblast gun 21 is set to swing in a reciprocating manner, so that the sandblast range of the middle part sandblast gun 21 is enlarged, the large-area sandblast of the 12 faces of the target can be completed through the swinging sandblast of the middle part sandblast gun 21, and the sandblast efficiency is improved. Meanwhile, the middle sand blasting gun 21 swings in the sand blasting process, so that the sand blasting force is softer, the phenomenon that local sand blasting roughness deviation is large due to continuous sand blasting at a certain position is avoided, the sand blasting effect is more uniform, and the sand blasting roughness deviation is effectively reduced. Because middle part sand blasting gun 21 constantly swings at the sandblast in-process to the angle that forms between the sandblast face of middle part sand blasting gun 21 and target 12 constantly changes, the constantly swing of middle part sand blasting gun 21 cooperates with the removal of conveyor 54, effectively guarantees the regional sandblast homogeneity of each sandblast, thereby effectively prevents to receive the sandblast time difference between the sandblast position of difference and cause the problem that the sandblast roughness is different to appear.

The middle connecting rod 33 is fixed on the middle rod connecting hole 31, the middle connecting rod 33 can rotate in the middle rod connecting hole 31 before being locked, after the rotation angle of the middle connecting rod 33 is determined, the middle connecting rod 33 is locked and fixed in the middle rod connecting hole 31, and meanwhile, the middle connecting rod 33 can adjust the distance from the middle base 34 to the plane target sand blasting surface by adjusting the length of the middle connecting rod 33 inserted into the middle rod connecting hole 31. After the middle gun connecting rod 36 is inserted into the base hole 35, before the middle gun connecting rod 36 is locked in the base hole 35, the middle gun connecting rod 36 can rotate in the base hole 35, the sand blasting angle of the middle sand blasting gun 21 can be further adjusted through the middle gun connecting rod 36, meanwhile, the length of the middle gun connecting rod 36 inserted into the base hole 35 can also be adjusted through adjustment, and therefore the distance from the middle sand blasting gun 21 to a plane target sand blasting surface can be adjusted.

The adjustment mode of the middle part sand blasting gun 21, the swing amplitude, the sand blasting position, the sand blasting angle and the sand blasting distance has multiple choices, and an operator can select different adjustment modes according to actual conditions to flexibly operate, so that the middle part sand blasting gun 21 is more accurate to adjust and more convenient to operate.
The blasting apparatus is provided with a side fixing rod 42, the side fixing rod 42 is fixed to the side of the blasting chamber 11, and the side blasting gun 41 is attached to the side fixing rod 42. The side blasting guns 41 are used to blast non-sputtered areas of the side of the target 12. The fixed and lateral part dead lever 42 of lateral part sand blasting gun 41, because the sandblast width in the non-sputtering area of the side of target 12 is less, lateral part sand blasting gun 41 can fix the setting, only need be fixed in lateral part dead lever 42, and when lateral part sand blasting gun 41 sandblasted the side of target 12, conveyor 54 transported the removal to the plane target to make lateral part sand blasting gun 41 accomplish comprehensive sandblast to the whole side of plane target.
