Description

Technical Field

[0001] The invention relates to the field of loading racks, and in particular to an error-proof loading rack. Background Art

[0002] At present, in the competition in the automobile market, in order to meet the ever-changing needs of consumers for different models and different configurations, the vehicle manufacturing method is in the context of flexible production. One workshop often produces multiple models mixed and multiple configurations of the same model.

[0003] Since the installation methods of different configurations of some parts are the same and the differences are small, they are difficult to identify with the naked eye. Therefore, mis-installation is likely to occur during the production process. This situation is particularly common in automobile assembly workshops with a large number of manual assembly environments, such as shift covers, rear cover wiring harnesses, wheel covers, gasoline door labels, ABS pumps, etc.

[0004] The known solution is to light up the rack to prevent mistakes. Production line workers scan the vehicle assembly list or RFID to automatically read the vehicle RFID tag to obtain the vehicle model configuration. The corresponding material on the rack at the line will automatically light up to remind the assembler to take the correct material. However, this lighting method is only a reminder and not mandatory, and there is still a possibility of taking the wrong material. Summary of the invention

According to the different information about the vehicle configuration in the vehicle information of the car 3, the control box 11 controls the corresponding cylinder 5 to move with the display panel 6, prompting the operator to install the materials correctly, and displaying the vehicle information and material information through the display screen 7. The control box 11 is based on the Raspberry Pi PC, through the integrated relay, and completes the development of the python program template. After placing the corresponding materials on the shelf 8, the friction at the bottom of the material box can be reduced by the wheel hub 10 to facilitate the movement of the materials. The first material rack 100, the second material rack 102 and the third material rack 104 can play the role of placing fixed types of materials, so that the materials are placed in an orderly manner. The first slider 601 and the second slider 602 on both sides of the plate body 600 allow the display panel 6 to slide along a fixed track.

[0041] The beneficial effects of the error-proof loading rack of the present invention are:

[0042] 1. The RFID tag is adsorbed on the roof of the vehicle body. When it passes the scanner position, the scanner will automatically read the vehicle information in the tag, and query the vehicle order information from the database according to the vehicle number obtained by the scanner. After the control box obtains the vehicle model configuration information, it controls the movement of the corresponding cylinder, and the rack cylinder opens. At the same time, the display screen above the rack displays the vehicle information and material information, which is convenient for operators to take the correct materials. The equipment uses the existing RFID technology as the basis, with Raspberry Pi PC as the core, obtains vehicle configuration information through the FIS database, and independently designs the cylinder error-proofing rack to achieve the purpose of mandatory error-proofing.

[0043] 2. The control box uses the cheap and easily available Raspberry Pi as a processing computer. By integrating relays and completing the development of Python program templates, it can be conveniently connected to external display screens, cylinder solenoid valves and other actuators. The control box is standardized and modularized, and can be quickly promoted and directly used in other industrial production environments.
