The utility model provides a kind of micro object adsorption confirmation pressure switch, including pipeline main part and MCU control module;Pipeline main part is equipped with gauge pressure sensor, and the both sides of gauge pressure sensor are equipped with detection pin, and two groups of detection pin bottom end are equipped in pipeline main part, and the other end of two groups of detection pin is connected differential pressure sensor away from pipeline main part, and gauge pressure sensor and differential pressure sensor are electrically connected with MCU control module. Through the cooperation of absolute pressure gauge pressure sensor and differential pressure type MEMS sensor, the suction nozzle adsorption state is determined, without the need for rear-end visual inspection, avoiding production failure and secondary processing, ensuring continuous operation of production line. At the same time, the device structure is adapted to the scene, responds quickly, can confirm adsorption before handling, reduces repeated operation caused by misjudgment, increases the accuracy of determination, and improves the overall efficiency of the production line.

The application discloses a kind of automatically slitting inductance protection bearing tape preparation equipment and preparation method thereof, comprising: conveying table, heat pressing device, cutting device and cooling device are sequentially arranged in conveying table two sides from left to right;Including the following steps: S1, accurate positioning is carried out to bearing tape by positioning structure and position is corrected;S2, bearing tape is contacted with heater by positioning pressing plate and is pressed down, and the edge of bearing tape is softened;S3, the both sides of bearing tape are cut simultaneously by blade;S4, bearing tape is rapidly frozen and cooled by liquid nitrogen injection part, and then the bearing tape piece is blown to the blanking transmission part by air injection part, and the blanking of single bearing tape piece is completed.The application effectively solves the problem of curling caused by uneven stress distribution by combining heating treatment, arc cutting and air blowing blanking, improves production efficiency, improves product quality and stability, reduces manual operation and error, and reduces production cost.

The utility model relates to the technical field of door locks, and particularly discloses a lock assembly with high installation adaptability and a door lock catch box. The lock comprises a lock body and a buckle box matched with the lock body, the lock body is provided with a circuit board and a Hall element electrically connected with the circuit board, and the buckle box is provided with a magnet matched with the Hall element and a telescopic piece used for adjusting the distance between the magnet and the Hall element. According to the utility model, the magnet and the telescopic piece are arranged in the buckle box, so that during actual installation, even if a gap between a door leaf and a door frame is too large, the distance between the magnet in the buckle box and the Hall element in the lock body can be adjusted by utilizing the telescopic piece, and the magnetic field intensity is increased along with the reduction of the distance between the Hall element and the magnet; the voltage or signal intensity output by the Hall element is also increased, so that the condition that the Hall element can be activated is achieved, the function of detecting and judging the opening and closing state of the door is achieved, the tedious work that due to actual door leaf production or installation errors, remanufacturing or installation is needed to solve the failure situation is avoided, and the adjusting mode of the scheme is higher in efficiency and more convenient.
