Abstract: Disclosed are a polyethylene glycol conjugate drug, and a preparation method therefor and the use thereof. Specifically, the present invention relates to a polyethylene glycol conjugate drug represented by formula A or a pharmaceutically acceptable salt thereof, a method for preparing the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof, an intermediate for preparing the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof, a pharmaceutical composition comprising the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof, and the use of the polyethylene glycol conjugate drug or the pharmaceutically acceptable salt thereof in the preparation of a drug.

Abstract: Disclosed is a panel sorting device which includes a placement rack, an alignment device, and a classification robotic arm. The placement rack has multiple layers. In each layer of the placement rack, at least one panel is placed according to a predetermined sequence and corresponding position. The alignment device is configured to obtain the positional deviation of the panel moved on a production line. The classification robotic arm is configured to correct the panel position in the placement rack based on the positional deviation acquired by the alignment device, and place the panel in the corresponding layer of the placement rack according to the predetermined sequence and position. The panel sorting device can quickly grab the panel and automatically sort the panels according to the product's specifications. As a result, it can increase demand for automated handling and production yield, and reduce costs and save installation space.

Abstract: The invention discloses a panel sorting device. The panel sorting device comprises a placement rack, an alignment device, and a classification robotic arm. The placement rack has multiple layers. Each layer of the placement rack places at least one panel according to the sequence with specification at corresponding position. The alignment device is used to obtain the positional deviation of the panel moved on a production line. Wherein, the classification robotic arm corrects the panel position based on the information of the positional deviation acquired by the alignment device, and places the panel in accordance with its sequence and specification to the corresponding position in the layer of the placement rack. To implement the panel sorting device of this present invention can quickly grab the panel and automatically sort according to the product's specifications. As a result, improve the efficiency of automated handling and production yield, and reduce costs and save installation space.
