The application discloses a needle cutting machine for fish-eye pin rows, which comprises a base, a pressing mechanism, a linkage mechanism, a needle pushing mechanism, a material feeding mechanism and a fish-eye pin row, the base comprises a vertical section and a horizontal section, and the included angle between the vertical section and the horizontal section is a right angle; the pressing mechanism is arranged on the vertical section of the base and is used for cutting the connection between the fish-eye pins; the needle pushing mechanism is arranged on the horizontal section of the base, and the material feeding mechanism is connected with the needle pushing mechanism; through cooperation of the pressing mechanism, the linkage mechanism, the needle pushing mechanism and the material feeding mechanism, the semi-automatic needle cutting work is realized, the problems that the automation cutting needs high investment and long delivery period and cannot meet the requirements of small batches and sample pieces in the experimental stage are solved, the problem that the manual bevelled forceps cannot meet the size requirements of the shoulder part of the fish-eye pin after cutting is solved, and the problem of low manual cutting efficiency is also solved.

The present application relates to the technical field of ultra-thin PI substrate processing equipment, in particular to a slit coating thickness control structure for ultra-thin PI substrate processing, which comprises a transverse guide rail, an L-shaped support and a scraper mold, the front end of the transverse guide rail is provided with a screw rod transmission mechanism for providing transverse power, the front end of the screw rod transmission mechanism is slidably connected with a guide rail, the front end of the guide rail is provided with a pressure plate, the rear end of the pressure plate is welded with a mounting plate, the upper ends of the transverse guide rail are provided with L-shaped supports on both sides, and the upper ends of the L-shaped supports are connected with gaskets in the middle. The mounting plate and the pressure plate constitute an L-shaped limiting baffle, the pressure plate is attached to the base of the slit coater, and the polyimide is constrained, so that the edge of the slurry is prone to "edge bulging" or shrinkage due to surface tension during scraping. The constraints on both sides can physically block the overflow of the slurry, force the film layer to be more consistent in width and thickness, and reduce the edge effect.

This utility model discloses a bedside table with a concealed compartment component, relating to the field of furniture technology. It includes a bedside table body with several drawer boxes inside. Each drawer box has a sliding rail on both sides, and sliders fixed to the left and right sides of the drawer box, sliding within the sliding rails. A concealed compartment is located at the rear of the drawer box, containing several upper and lower storage compartments. This utility model's sliding pull-out mechanism and multi-compartment layout achieve secure storage of personal items and privacy protection. The concealed compartments fit perfectly with the bedside table, ensuring concealment and effectively utilizing cabinet space, increasing storage capacity without increasing size. The sliding rail and slider structure facilitates access to each storage compartment while enhancing the overall uniformity and aesthetics. It breaks through the traditional bedside table design, meeting daily storage needs while providing private storage space, balancing functionality and aesthetics.

The application provides a method and device for determining temporary tension of a segmental assembly beam by a bonding method, and relates to the technical field of bridge construction. The method comprises the following steps: obtaining the total tension of the temporary prestressed tendon of the segmental assembly beam by the bonding method, the first distance between the tension point on the top plate and the centroid line, and the second distance between the tension point on the bottom plate and the centroid line; determining the tension on the top plate as the ratio between the total tension and the first value, and determining the temporary tension of the single precision rolled threaded steel bar on the top plate based on the tension on the top plate; wherein the first value is the sum of the ratio between the first distance and the second distance and 1; determining the tension on the bottom plate as the product between the tension on the top plate and the second value, and determining the temporary tension of the single precision rolled threaded steel bar on the bottom plate based on the tension on the bottom plate; wherein the second value is the ratio between the first distance and the second distance. The application can ensure the uniformity of the bonding seam width during tensioning, and the bridge alignment is more accurate.
