This publicly provides the storage device of the box, including the laser sensor; the displacement sensor; the processor is used to receive the distance between the shuttle and the obstacles, and the first preset value is compared to determine the freight and its phase of the inventory.Whether there are boxes on the adjacent position; if there is a box in the stock position to be inventory, the alarm information is output; if there is no box in the goods to be inventory and its adjacent cargo, it will be stored directly to store the box directly.In the stock of the inventory; if there is no case in the stock of the inventory, there is no box and the box on the adjacent cargo.The distance between the most adjacent boundaries and is recorded as L. When L <L <L 0 At the time, output the alarm information; when L 0 ≤L ≤L 1 At the same time, the box is stored directly on the freight for the inventory; 0 = Box width+minimum value of the box spacing; L 1 = The width of the box+the maximum value of the pitch of the box.

The invention relates to a bilateral sealing stop valve which comprises a valve body and valve elements. The stop valve adopts the technical essentials that a throttling orifice is arranged on the longitudinal central line of the valve body, and the valve elements are arranged on the transverse central line of the valve body; the valve elements are symmetrically arranged in valve element holes attwo sides of the throttling orifice; the valve element hole at the front end of a valve element sealing stop is internally provided with a sealing assembly; a positioning body and a nut are sleeved outside the valve elements at two ends of the valve element holes and fixed on the valve body through a fixing press cap; a hand wheel which is clamped by a flat key and fixed by a jam nut is sleeved outside the nut, and a valve element gear is arranged outside the nut between the hand wheel and the fixing press cap; the valve body is connected with a bearing block through a bolt, and the bearing block is internally provided with a slide bearing; a transmission shaft is fixed on the bearing block through the slide bearing; and two ends of the transmission shaft are provided with a transmission shaft gear engaged with the valve element gear. The invention has the advantages of flexible and compact structure, exact and accurate sealing, good sealing quality and low manufacturing cost and is an important improvement for the safety performance of a float type liquid level metering system of a pressure container.

A laser cleaning method for deoxidation, comprising the steps of: setting parameters for an upper computer according to laser cleaning requirements; a control unit dividing a cleaning track pattern into regions; The machine sends an instruction to make the control unit turn on the laser to start laser cleaning; the control unit judges the area corresponding to the current cleaning position in real time, and determines the current laser power; the control unit configures the obtained laser power to the laser according to the communication protocol. The invention can effectively realize deoxidation, improve the cleaning quality, avoid damage to the substrate, is easy to operate, can adapt to different cleaning environments, saves automation control costs, and improves cleaning efficiency. This method can be widely used in laser cleaning.

The invention relates to a flexible stretchable sensor, belongs to the technical field of sensors, and solves the problems of easy damage, inaccurate detection results and unreasonable circuit design of the existing flexible stretchable sensor. The flexible stretchable sensor disclosed in the present invention includes an M×N array formed by arranging M×N detection units; wherein each of the detection units includes a stretchable part and a non-stretchable part; The sensing module is arranged on the non-stretchable part, and is connected with the sensing module of the adjacent detection unit through the wire set on the stretchable part. When in use, the macroscopic stretching function is realized through the stretchable part, and the detection function of the non-stretchable part is not affected at the same time. Through the structural design of the non-stretchable part, it can be avoided that the sensing module is stretched and the electrical performance is deteriorated, so that the reading value of the sensor is stable and reliable. Moreover, the use of the array design makes the overall system structure smaller, the control circuit is simple, and the cost is low.

The invention discloses a fruit container with a control device and belongs to the field of agricultural mechanical tools. The fruit container comprises a hollow upright, blades and a collection dishpositioned inside the hollow upright and further comprises a rotating sleeve rotatably connected with the hollow upright, an upper collection port is arranged at the upper end of the hollow upright, afirst rotating shaft and a second rotating shaft are rotatably connected on the hollow upright, the first rotating shaft is fixedly connected with the blades, a first gear is fixedly connected on thefirst rotating shaft, two ends of a third rotating shaft are fixedly connected with a third gear and a fourth gear respectively, the first gear and the fourth gear are meshed, and gear teeth meshed with the fourth gear are arranged on the inner wall of the rotating sleeve. The fruit container can effectively prevent fruits from falling when the fruits at high positions are picked, so that the fruits are ensured not to be damaged, taste and appearance of the fruits are ensured, and convenience is brought to collection and storage of the fruits.
