The utility model discloses through being provided with collecting device, can drive circuit board and the surface contact of the adhesion layer while rotating wheel rotation replaces the circuit board that needs drilling, removes the debris on the circuit board surface as far as possible through the adhesion layer while driving the operation of conveyer belt, has facilitated the processing use of back, and has improved the quality of circuit board, makes the subsequent processing not because the debris on the surface appears influence.

This invention provides a method for training a multi-task processing model and related products. The method includes acquiring training data for the multi-task processing model and multiple teacher models, wherein the multi-task processing model is configured to perform multiple text analysis tasks in speech synthesis, and each teacher model is configured to perform a single text analysis task; determining a target loss for the multi-task processing model based on the prediction results of the teacher models and the multi-task processing model on the training data; and optimizing the training of the multi-task processing model based on the target loss. Through the technical solution of this invention, the multi-task processing model can be trained to be applied to multiple tasks simultaneously, breaking the traditional pipelined combination analysis method and achieving a balance between quality and performance. In addition, this invention also provides a method for speech synthesis.

The utility model relates to blood clotting test device technical field, a blood clotting test reaction plate inclination control device, include: bearing frame, movable frame is established on bearing frame, movable frame is for the U-shaped frame, and the inside wall of movable frame is equipped with assembly slot, positioning board is established above the arbitrary one end of movable frame, with bearing frame fixed connection, and the angle between the top surface of positioning board and movable frame is 45 DEG, first limit component is established on the top surface of bearing frame, with can along the top surface of bearing frame sliding, and the top of first limit component is equipped with the plugboard, and the outside wall of movable frame is equipped with the limit slot. The utility model not only can save operator's physical strength, can also keep the stability of V type reaction plate, when V type reaction plate keeps 45 DEG inclination state, virus liquid and red blood cell suspension will not spill, will not cause pollution. The utility model can guarantee that the inclination time is sufficient and the inclination angle is always invariable, therefore the determination result is more accurate, and deviation will not appear.

This invention relates to a fully automatic CNC circular saw for pipe cutting, belonging to the field of automation equipment technology. It includes a worktable, an operation panel mounted on top of the worktable, a discharge channel inside the worktable, a support cover mounted on one side of the operation panel, a feeding trough located in the middle of the side of the operation panel near the support cover, a discharge trough located on top of the operation panel, and an electric slide rail mounted on the side of the operation panel away from the support cover. A top plate is mounted on the moving end of the electric slide rail. This invention, by setting up a feeding component, can quickly adapt to the support and positioning of circular pipes of different diameters, automatically calculate and position the cutting length, improving the accuracy and efficiency of fixed-length cutting; by setting up a fixing component, the circular pipe is fixed from multiple directions, eliminating shaking and offset during cutting, significantly improving the flatness and dimensional accuracy of the cut.

This invention provides a turbine blade tipping fixture and tipping method. The tipping fixture includes a support unit, a clamping unit, a locking unit, and an angle adjustment unit. The support unit includes a column, and the clamping unit includes a carrier and a blade clamping member that accommodates and clamps the turbine blade. A pressure plate is detachably connected to the carrier. The pressure plate and set screw of the locking unit limit and press the blade clamping member into the U-shaped portion of the carrier. The angle adjustment unit includes a rotating shaft and a knob. The rotating shaft passes through the column, and the knob is connected to one end of the rotating shaft on one side of the column. The carrier is connected to the other end of the rotating shaft on the other side of the column. The rotating shaft drives the carrier and the blade clamping member to rotate. Using this tipping fixture and method, the turbine blade is fixed and the grinding wheel position is moved back and forth during tipping repair, improving the tipping field of vision. During the tipping process, the condition of the blade tip thin blade area can be accurately judged, and the relative position of the blade and the grinding wheel can be adjusted at any time to remove material evenly, thus improving the repair quality and efficiency.
