Description

Technical Field

[0001] This utility model relates to the field of manufacturing technology, and in particular to a material handling error prevention and control system. Background Technology

[0002] Against the backdrop of rapidly changing home appliance technology, personalized consumer demand, and diversified market development, the types and demand for home appliances are also growing rapidly. Each production line in a factory workshop often has to produce several or even dozens of models of home appliances at the same time. Because a single production line produces too many models of home appliances at the same time, and the production pace is fast, workers are prone to picking the wrong materials during the assembly process of home appliances in the traditional production method, which leads to an increase in product quality problems. Utility Model Content

[0003] This utility model provides a material handling error prevention and control system to facilitate correct material handling during the assembly of home appliances.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] This utility model provides a material handling error prevention and control system, including: multiple storage compartments, a label controller, an industrial control computer, infrared sensors, and a fixed barcode scanner. Each of the storage compartments is equipped with an LED screen and a speaker. The multiple storage compartments are arranged in a matrix. Component materials are placed in each storage compartment. The multiple LED screens are directly connected to the label controller, which is connected to the industrial control computer via a serial port. The multiple speakers are connected to the industrial control computer via audio output jacks. The fixed barcode scanner is connected to the industrial control computer via a network port and is used to scan equipment barcodes to obtain data. The device barcode information includes the device type, and the device type corresponds one-to-one with the storage compartment number. The label controller is configured with a mapping relationship between the storage compartment number and the LED screen number. The industrial control computer is wirelessly connected to the infrared sensor. The infrared sensor is used to send a trigger signal to the industrial control computer when it detects human information. After receiving the trigger signal, the industrial control computer controls the LED screen of the corresponding device storage compartment to light up and display an audio prompt based on the received device barcode information and the mapping relationship between the storage compartment number and the LED screen number.

[0006] In a preferred embodiment, a photosensor is also included, which is used to detect ambient brightness information and send it to the industrial control computer, which is used to adjust the display brightness of the LED screen according to the ambient brightness information.

[0007] In a preferred embodiment, each of the LED screens is fixed to the upper or lower part of each of the storage compartments by a quick-release buckle structure.

[0008] As a preferred embodiment, ABS plastic buckles are provided at the four corners of each LED screen, and buckle slots are reserved at the corresponding positions of each storage compartment. The buckles and the slots adopt an asymmetrical design.

[0009] In a preferred embodiment, the infrared sensor is also used to detect the passage of home appliances. When a home appliance is detected passing through the station, a signal is triggered to the fixed barcode scanner, which is used to automatically scan the device barcode after receiving the signal.

[0010] In a preferred embodiment, the multiple storage compartments are integrated into one unit.

[0011] In a preferred embodiment, a camera is also included. The camera is communicatively connected to the industrial control computer. The camera is used to acquire material handling action data and send it to the industrial control computer. When an abnormal material handling action is detected, the industrial control computer controls the LED screen of the target storage compartment to switch to a red flashing mode and plays an error correction voice command through the speaker.

[0012] This invention involves installing an LED screen and a speaker in each storage compartment. A fixed barcode scanner scans the equipment barcode to obtain its information, which includes the equipment type and a one-to-one correspondence between the equipment type and the storage compartment number. A label controller is configured with a mapping relationship between the storage compartment number and the LED screen number. An infrared sensor sends a trigger signal to the industrial control computer upon detecting human presence. Upon receiving the trigger signal, the industrial control computer, based on the received equipment barcode information and the mapping relationship between the storage compartment number and the LED screen number, controls the corresponding storage compartment's LED screen to light up and provides an audio prompt. This solves the problem of operators relying excessively on visual observation of a single LED display screen, eliminating the need to determine the specific storage compartment location based on LED display information. It achieves the convenient effect of knowing which storage compartment is lit and where to retrieve the material. Simultaneously, the voice prompts address the issue of over-reliance on visual observation, achieving an integrated error-proofing control effect through both screen-lit material retrieval and voice prompts.
