The invention belongs to the technical field of garment processing production lines, and particularly relates to an intelligent distribution production line for garment processing, which comprises a mounting plate, equidistant main support rails are fixedly connected to the mounting plate, a transfer belt is slidably connected to the mounting plate, equidistant L-shaped push rods are fixedly connected to the transfer belt, and symmetrical equidistant rollers are jointly arranged on the upper sides of the equidistant main support rails. The rollers which are symmetrically distributed are jointly and rotationally connected with a connecting frame, a tooth-shaped frame is arranged on the lower side of the connecting frame, the lower side of the tooth-shaped frame is rotationally connected with fixing plates in a linear array, the lower side of the main supporting rail is fixedly connected with a zigzag plate, and the lower portion of the zigzag plate is fixedly connected with a secondary supporting rail. By changing the separation mode when the hanger moves from the main supporting rail to the secondary supporting rail, the idler wheel and the main supporting rail are stably separated in a rolling mode, the idler wheel is kept to be attached to the guide plate all the time, a guide rail where the idler wheel runs does not need to be replaced, and therefore the probability that the hanger derails is reduced.

The application discloses a preparation method of a semiconductor device, which comprises the following steps: providing a substrate; forming a stack layer on the surface of the substrate, wherein the stack layer comprises a first type region and a second type region, and the first type region and the second type region are arranged adjacently; forming a mask layer on the surface of the first type region; forming a shielding layer on the sidewall of the mask layer, wherein the shielding layer shields part of the surface of the second type region; etching the second type region by taking the mask layer and the shielding layer as masks, the second type region shielded by the shielding layer is formed with a lateral erosion, and the width of the shielding layer is greater than the maximum width of the lateral erosion of the second type region; removing the shielding layer to expose the part of the second type region shielded by the shielding layer; and removing the exposed part of the second type region to make the sidewall of the first type region vertical and flush, so that the preparation method of the semiconductor device can reduce the over-etching influence on the adjacent sidewalls in the etching process, and improve the product performance and yield.

The invention discloses an air exhaust ring piece, a process cavity, thin film deposition equipment and an air exhaust ring piece installation method. The air exhaust ring piece is mounted in a chamber of the process cavity; the air exhaust ring piece comprises an air exhaust lining and an air exhaust ring; the air exhaust lining is installed in the cavity, and an annular lap joint groove is formed in the air exhaust lining. The air exhaust ring is in lap joint in the annular lap joint groove, and an air exhaust channel for connecting the cavity with the outside is formed between the air exhaust ring and the air exhaust lining; a leakage-proof piece is arranged at the joint of the cavity, the air exhaust lining and the air exhaust ring and used for eliminating tolerance clearances at the joint of the cavity, the air exhaust lining and the air exhaust ring so as to guarantee the air tightness of the air exhaust channel. The tolerance clearance at the joint of the cavity, the air exhaust lining and the air exhaust ring is eliminated through the leakage-proof piece, it is guaranteed that the air exhaust ring piece has good air tightness in the air exhaust process, and the situation that the technology is affected by air leakage is avoided.
