The invention provides a component mounting and dispatching optimization method for a chip mounter on basis of a quantum neural network. The component mounting and dispatching optimization method comprises the steps of establishing a mathematical model of the sum of paths required by the operation of mounting all components on a printed circuit board (PCB) according to an operating principle of mounting the components by a suction nozzle of the chip mounter, wherein the distances between all the mounted components and different feed tanks are taken as input vectors of the quantum neural network, and all weighting values are set as small random numbers, and given input vectors and target output vectors of a training set are provided; and calculating overall optimal solution of the established mathematical modeling by adopting a three-layer quantum neural network algorithm, thus obtaining an optimized component mounting and dispatching scheme corresponding with the sum of the shortest mounting patches of all the components, the optimal mounting order of all the components, and the arrangement positions of feeders of the components in the feed tanks. The component mounting and dispatching optimization method constructs the component mounting and dispatching mathematical model which takes both the component mounting order and the feeder arrangement positions into consideration, obtains the optimal control on the mounting and dispatching of the components in the PCB, shortens the mounting time of single-end arch components, and enhances the mounting and production efficiency of the components of the chip mounter.

The invention relates to a flow injection microscope raman spectrum device for water pollutant detection and a detection method and belongs to the technical field of monitoring for the water environmental pollution. The device comprises a sample feeding module, a power supply module, an optical collecting module, a detecting analysis module, a result display output module and a positioning and wireless communication module, wherein the power supply module is used for supplying electric energy to the whole detection device and performing power supply management; the sample feeding module is used for conveying a to-be-detected water sample into a micro-fluidic chip through a micro-pump and a filtering device; the accurate positioning and focusing between the micro-fluidic chip and a microscope raman module are realized by adjusting the position of a displacement adjusting platform; a raman scattered signal of the to-be-detected water sample is collected by the optical collecting module, is subjected to photovoltaic conversion and then is sent to the detecting analysis module for testing the ingredients and contents of the pollutants in the to-be-detected water sample; a detection result is output and displayed on a display terminal; the position of a to-be-detected water sample point and the condition of the water pollution are transmitted to a superior monitoring center through the positioning and wireless communication module, so that the remote real-time monitoring is realized. The flow injection microscope raman spectrum device provided by the invention is compact in structure, is convenient in operation and accurate in detection, and can be used for realizing quick online detection on the water quality of river, lack, urban sewage, and the like.

The invention discloses a scalpel placement rack and belongs to the technical field of medical supplies. The scalpel placement rack comprises a fixed rack, a placement layer and multiple partition parts, wherein the placement layer is obliquely and fixedly mounted in the fixed rack, the multiple partition parts are arranged below the placement layer and arranged at equal intervals, multiple slits are formed in the placement layer, and partitions of the partition parts are arranged in the slits. Each partition part comprises a partition, a support frame and a movable frame, the partition is mounted below the slit of the placement layer and on one side of the movable frame, the support frame is mounted below the movable frame, and the partition and the movable frame are movably connected through buckles. The scalpel placement rack is provided with the oblique placement layer, scalpels are placed at a placement end and slide automatically to an arrangement end, the partitions are sprung up to separate the scalpels, the problems of wear and damage between the scalpels are solved, and the scalpel placement rack has the advantage of effectively separating the scalpels, and reduces manual labor.

The invention discloses a cylindrical battery connection seat, through the fixed module and track permanent magnet arranged on the bottom plate and the locking plate above the fixed module, the electromagnet coil and the iron core arranged on the side of the battery connection seat, through the The attraction of the electromagnet makes the battery automatically identify the positive and negative poles. At the same time, squeezing the wedge-shaped block on the locking plate will squeeze the positive and negative shrapnel, and the wedge-shaped block will be inserted into the shrapnel combination to expand the shrapnel combination. By fixing the shrapnel Combined to drive the positive fixed arm and the negative fixed arm to move along the slide rail through the small pulley, and then clamp the cylindrical battery rolled into the fixing device, because the battery is elastically fixed by the elastic force of the shrapnel to prevent the fixing device from crushing the battery. It not only solves the problem of aligning and fixing the positive and negative poles of the cylindrical battery, but also shortens the battery placement time and improves the efficiency of battery arrangement and fixing.

The invention relates to a method for forging a workblank of a transmission disc of a locomotive. A selected raw material is cut into a blank according to weight; the blank is placed into a heating furnace to be heated to 1100 DEG C to 1180 DEG C; the heated blank is placed into a lower mold cavity of a pre-forging lower die to be positioned, the blank is forged to enable a material of the blank to flow in a pre-forging mold cavity of a pre-forging upper die and the pre-forging mold cavity of the pre-forging lower die in the free upsetting radial direction, and a molded pre-forging piece forms a corresponding thinning part at a protrusion bridge part and correspondingly forms a thickening part at the position of a cavity; the pre-forging piece is turned over to be placed into the mold cavity of the pre-forging lower die to be automatically positioned, the pre-forging piece is forged to enable the material of the pre-forging piece to flow in finish-forging mold cavities of a finish-forging upper die and a finish-forging lower die in the radial direction, and a molded finish-forging piece outwards extends along a disc body to form three uniformly-distributed lug parts and a shaft sleeve located at the middle portion of the disc body; and parting-line flashes of the finish-forging piece are cut off, connecting skin is punched away, and the workblank of the forging piece is prepared. By means of the method, the manufacturing cost is reduced, the production efficiency is improved, the complete streamline of a material of the transmission disc product of the locomotive can be kept, and the transmission disc of the locomotive has the excellent overall performance.
