Description

Technical Field

[0001] The present invention relates to the technical field of vehicle assembly, and more specifically, to a method for installing positioning labels for multiple vehicle models. Background Art

[0002] In the process of automobile assembly, the positioning methods are diverse. Some positioning tags are placed on the roof, some on the vehicle floor, some on the vehicle dashboard, and some on the front windshield or window. At the same time, according to the differences in the properties of the positioning tags themselves, their placement methods are also different. In addition, different models have different positioning tag placement methods due to their own characteristics. This diversity seriously restricts the determination of the installation position of the tag reader. When different models are mixed on the production line, multiple readers often need to be installed at the same station to ensure that the positioning tags of different models can be identified and the normal progress of the production process can be guaranteed.

[0003] In the prior art, at the door removal station of automobile assembly, the vehicle information is written into a reusable positioning tag, and then the positioning tag is placed at the corresponding different positions of the vehicle according to the different models. When the vehicle is OK to roll off the production line, the vehicle information in the reusable positioning tag is transferred to the disposable positioning tag, and the disposable positioning tag is affixed to specific different positions according to the different models. However, this solution has the following problems: due to the different production line processes, the existing positioning tag positions need to be adjusted in different process sections; when different models are mixed on the production line, the same station is very likely to need to install multiple readers and writers to identify the positioning tags of different models, which greatly affects the production efficiency. Summary of the invention

[0004] One purpose of the present invention is to provide a method for installing multi-vehicle positioning tags to solve the problem that the aforementioned circulating positioning tags need to be adjusted in different process sections, and multiple readers and writers may need to be installed at the same workstation, which seriously affects production efficiency.

[0005] According to a first aspect of the present invention, a method for installing multi-vehicle positioning tags is provided, comprising the following steps:

[0006] Print one-time positioning labels at set stations;

[0007] Transferring the information in the positioning tag on the vehicle body to the disposable positioning tag;

[0008] Placing the disposable positioning tag on a preset fixing device;

[0009] In the first operation process, the read / write head station reads the disposable positioning tag on the preset fixture;

[0010] Take out the one-time positioning label on the preset fixture, and then stick it to the ETC installation position of the windshield;

[0011] In the second operation process, the read / write head station reads the one-time positioning tag information of the ETC installation location.

[0012] Optionally, the set workstation is a left door removal workstation on the PBS system.

[0013] Optionally, the one-time positioning label printed by the setting station includes a vehicle identification code, a vehicle model code, a production batch number, and a color code.

[0014] Optionally, the information in the positioning tag on the vehicle body transport vehicle pre-stores part of the vehicle body basic information, which includes the original order information of the vehicle body and the supplier's parts source information. The part of the vehicle body basic information is written before the vehicle body enters the PBS system.

[0015] Optionally, transferring the information in the positioning tag on the vehicle body to the disposable positioning tag includes: acquiring the information in the positioning tag on the vehicle body through wireless radio frequency identification, and transmitting the information to the disposable positioning tag.

[0016] Optionally, placing the disposable positioning tag on a preset fixing device includes:

[0028] Various exemplary embodiments of the present invention will now be described in detail with reference to the accompanying drawings. It should be noted that the relative arrangement of components and steps, numerical expressions and numerical values ​​set forth in these embodiments do not limit the scope of the present invention unless otherwise specifically stated.

[0029] The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses.

[0030] Technologies, methods, and equipment known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, the technologies, methods, and equipment should be considered part of the specification.

[0031] In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not limiting. Therefore, other examples of the exemplary embodiments may have different values.

[0032] The present invention proposes an embodiment of a method for installing a positioning tag for multiple vehicle models. Specifically, Figure 1 As shown, the following steps are included:

[0033] Print one-time positioning labels at set stations;

[0034] In the embodiment of the present invention, the setting station is a left door removal station on the PBS system (pre-mass production system). The one-time positioning label printed by the setting station includes the vehicle identification code, vehicle model code, production batch number, color code, engine model, interior configuration code, etc. By printing and attaching the one-time positioning label at this early stage, the foundation is laid for vehicle identification and information tracing in the subsequent entire production process.

[0035] Transferring the information in the positioning tag on the vehicle body to the disposable positioning tag;

[0036] Among them, the body transport tool such as a skid has some basic body information pre-stored in the positioning tag on the body transport tool, including the original order information of the body, the source information of supplier parts, preliminary welding process parameters and other information. The basic body information is written before the body enters the PBS system. Radio frequency identification (RFID) technology or near field communication (NFC) technology is used to quickly and accurately read and transmit the information in the tag on the skid to the one-time positioning tag. This process ensures the continuity and integrity of the vehicle information, so that the one-time positioning tag has more comprehensive vehicle background information from the beginning, which is convenient for subsequent production links to perform precise operations based on this information.

[0037] Placing the disposable positioning tag on a preset fixing device;

[0038] Specifically, in an embodiment of the present invention, placing the disposable positioning tag on a preset fixing device includes: placing the disposable positioning tag on a positioning tag carrier; and hanging the positioning tag carrier on the stud hole of the left door.

[0039] In an embodiment of the present invention, the positioning tag carrier is made of lightweight plastic or metal material, which can ensure that the positioning tag carrier can firmly clamp the disposable positioning tag and prevent the disposable positioning tag from shaking, falling off or being damaged during the movement and assembly of the vehicle, and will not cause any obstruction to the information reading of the disposable positioning tag. The shape of the positioning tag carrier is adapted to the geometric shape of the left door stud hole. The positioning tag carrier has a specific hook or slot structure so that it can be conveniently and firmly hung on the stud hole. The left door stud hole is selected as the hanging position because at this stage of automobile production, the left door stud is in a relatively exposed and easy-to-operate area. At the same time, during the subsequent assembly of the surrounding parts of the door (such as the installation of the door interior panel, the assembly of the window lifting mechanism, the installation of the door lock and the anti-theft system, etc.), this position will not be blocked or interfered by other components, and the disposable positioning tag can always be kept within the effective reading range of the read-write head. In addition, the position of the left door stud is relatively close to the vehicle's electrical control module and data transmission line, which is conducive to rapid data interaction and signal transmission during information reading, reducing signal attenuation or delay.

[0040] In the first operation process, the read / write head station reads the one-time positioning tag on the preset fixing device; wherein the first operation process is configured as a time period from the removal of the vehicle door to the chassis going online.

[0041] Take out the one-time positioning label on the preset fixture, and then stick it to the ETC installation position of the windshield; specifically, use a plastic crowbar with a fine tip or a magnetic extractor to remove the label from the carrier. The ETC installation position is located in the upper half of the windshield, close to the area of ​​the rearview mirror mounting base. By sticking the one-time positioning label to the ETC installation position of the windshield, it will not be affected by the installation or operation of other components in subsequent production processes (such as vehicle electrical system debugging, appearance inspection, final quality inspection, etc.), ensuring the stability of the label; in the vehicle production workshop, this position is relatively open, which is convenient for the read-write head to scan and read the one-time positioning label from different angles and distances. Whether it is a quality inspection station when the vehicle is stationary or a data collection station when the vehicle is moving slowly, the read-write head can easily obtain the information on the label.

[0042] In the second operation process, the read / write head station reads the one-time positioning tag information of the ETC installation location. The second operation process is configured as the time period from the first-line point of the chassis to the time before the vehicle leaves the warehouse.

[0043] In an embodiment of the present invention, the method for installing multi-model positioning tags also includes: when the first line of chassis is online, after the read / write head station reads the one-time positioning tag information, the chassis assembly parameters are adjusted according to the vehicle configuration information, and the chassis assembly parameters include suspension system adjustment parameters and drive shaft connection methods. Specifically, when the first line of chassis is online, after the read / write head reads the one-time positioning tag information, the production management system accurately adjusts the operating parameters of the robot arm on the chassis assembly line according to the specific configuration information of the vehicle (such as the vehicle's curb weight, power system type, suspension system specifications, etc.), to ensure that the installation position of the chassis components (such as the engine, transmission, suspension components, wheels, etc.) is accurate, and the preload force can be adjusted and calibrated according to the characteristics of the vehicle during the installation process. At the comprehensive performance test station performed after the whole vehicle is assembled, the read / write head reads the one-time positioning tag information, and the detection system can automatically select appropriate detection items and standards based on the vehicle configuration information.

[0044] In the present embodiment, the positioning tag is designed to be installed at a specific and uniform position on the car body. Since the installation position of the positioning tag is relatively fixed, during the planning stage of the workshop, the installation height, angle and distance of the read / write head can be determined based on this fixed position, so that the read / write head can efficiently and accurately obtain the one-time positioning tag information when the vehicle passes by.

[0045] Only one read / write head is required at the same workstation to meet the needs of co-production of different models. The single read / write head simplifies the equipment layout and control system of the production line. Compared with the situation where multiple read / write heads need to be installed for different models, it reduces the equipment procurement cost, installation and commissioning time, and subsequent maintenance workload.

[0046] There is no need to use a combination of cyclic positioning labels and one-time positioning labels, which reduces the type and quantity of labels required. In the production process, it reduces the errors that may occur due to label switching and information transfer. For example, at the OK offline station, if two labels are used, the information may be incomplete or wrong, resulting in the after-sales information after the vehicle is delivered being inconsistent with the actual production information; using a single label can avoid this situation.

[0047] The above describes in detail the structure, features and effects of the present invention based on the embodiments shown in the drawings, but the above is only a preferred embodiment of the present invention. It should be noted that the technical features involved in the above embodiments and their preferred methods can be reasonably combined and matched into a variety of equivalent schemes by those skilled in the art without departing from or changing the design ideas and technical effects of the present invention; therefore, the present invention is not limited to the scope of implementation shown in the drawings, and all changes made in accordance with the concept of the present invention, or modifications to equivalent embodiments with equivalent changes, which still do not exceed the spirit covered by the specification and drawings, should be within the protection scope of the present invention.
