Embodiment Construction

[0018] see figure 1 Shown, a kind of device of the present invention that detects missing spare parts comprises a weighing unit, a microcontroller (MCU) connected with the weighing unit, a trigger unit connected with the microcontroller, a button unit, a display unit, and an alarm unit with the control unit. Wherein, the weighing unit has an RS232 interface, and it performs data transmission with the MCU through the RS232 interface.

[0019] The weighing unit is an electronic scale with adjustable precision, memory function and RS232 output interface, which is used for weighing. Weigh the total weight of a spare part (including the box and all spare parts of a certain type contained in the box), and mark it as X grams; weigh a single sample of spare parts, and obtain the weight of a single spare part as a gram; and when triggered by the trigger signal each time, re-weigh the weight of the spare part, which is called X' gram. Whether the weight (data) of the spare part chang...

Abstract

The invention discloses an apparatus for testing accessories leakage, including a weighing unit, a microcontroller MCU connected to the weighing unit, a triggering unit connected to the microcontroller, a key-press unit for executing man-machine dialog, and a control unit controlled by the microcontroller MCU to control the production chain. The weighing unit is used to weigh and count the accessories, adding accessories to the production chain are strictly controlled, few or more accessories placing will alarm, pause the production chain operation until the manual handling falls to normal, then the production chain will operate again.

Description

【Technical field】 [0001] The invention relates to the technical field of production line operation, in particular to a method and device for detecting missing spare parts. 【Background technique】 [0002] In the operation of the production line, the problem of missing spare parts occurs from time to time, because the parts are large and small, they cannot be placed uniformly, and the positions are scattered. Operators need to manually install or put in spare parts. Long-term work fatigue and lack of concentration may easily lead to leakage. At the same time, the panic when commuting or changing shifts is also the main reason for missing releases. At present, most production units mainly have the following methods to prevent missing spare parts: [0003] 1. Start with the picking of materials, and pick the materials according to the requirements of the work order, and do not get more. If 500 spare parts are required to produce 100 sets of products, then only 500 parts can b...
