Problems solved by technology

[0003] Since the material sucker is arc-shaped on one side and has a stepped cavity inside, the volume is large and the shape is irregular, the processing is complicated and easy to deform
However, the material suction cup of the existing curved surface lithography machine has complicated processing technology and cumbersome procedures, and it is difficult to guarantee the quality of the parts during processing, resulting in a high rate of product quality defects, which not only leads to low production efficiency, but also affects the product qualification rate

Embodiment

[0031] see Figure 1-4 , a material suction cup processing method of a curved lithography machine, comprising a base part 1, the base part 1 comprising a circular arc surface 11 and a cavity surface 12, including the following processing steps:

[0032] S1. Process the six vertical surfaces of the cavity surface 12 from the billet aluminum block of the base piece 1, mill the upper and lower planes to make allowances, and use the pressure plate 2 to fix the base piece 1 on the worktable of the machining center (refer to figure 1 ), the arc surface 11 is pre-processed, and a unilateral allowance is reserved;

[0033] Among them, the reserved allowance for milling the vertical plane on the six sides is 0.4~0.6mm, and the unilateral allowance for the initial processing arc surface 11 is 0.9~1.1mm, so as to prevent the deformation in the later stage and ensure the overall processing accuracy;

[0034] S2. Clamp the base piece 1 with the flat-nose pliers 3 (refer to figure 2 ), f...

Abstract

The invention relates to the technical field of machining, and discloses a material suction cup machining method of a curved-surface photoetching machine, which comprises the following machining steps: machining a blank aluminum block of a substrate into six vertical surfaces of a cavity surface, milling the upper and lower planes to reserve allowance, fixing the substrate on a machining center workbench by using a pressing plate, primarily machining an arc surface, and machining a material suction cup of the curved-surface photoetching machine. A single-side margin is reserved; 7075 aluminum alloy is selected as a part material, a machine tool is selected from a bucket mountain machining center (the model number is DNM4505), machining tools are selected, a tungsten steel alloy coating aluminum milling cutter with the diameter being 30 and the blade length being 160 is selected as a machining arc surface curved surface, a small hole drill bit on the curved surface is selected according to the drawing size, the diameter of a small hole is 1.5, the model number of the drill bit is NACHi (LIST6594P), and the clamping technology and the machining technology are optimized. Therefore, the overall machining precision of the material suction cup is effectively guaranteed, the product reject ratio is reduced, the machining efficiency is improved, the normal operation requirement of machined parts in a machine can be met, and the product quality of the material suction cup is improved.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to a method for processing a material suction cup of a curved surface lithography machine. Background technique [0002] Mask Aligner, also known as: mask alignment exposure machine, exposure system, lithography system, etc., is the core equipment for manufacturing chips. It uses a technique similar to photo printing to print the fine patterns on the reticle onto the silicon wafer through the exposure of light. In the curved lithography machine, the material suction cup is one of the important components of the curved lithography machine. The main function of the suction cup is to absorb the glass workpiece and follow the drive motor to make the curved surface movement. Due to the processing of glass parts, the laser will be directly irradiated on the suction cup, and the suction cup should not be warped during long-term operation. High-precision contour requirements...
