[0018] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application.

[0019] To address the problems mentioned in the background section regarding existing automated automotive production lines' rapid switching positioning devices and high-precision rapid vehicle positioning devices for various platform models at prototyping assembly stations, this application provides a vehicle positioning device. In this device, an electronic control system controls the movement of the first to fourth three-axis modules according to pre-set motion parameters, causing the first to fourth three-axis modules to move to positions matching the chassis positioning holes of the target vehicle model, thus completing vehicle positioning. This solves the problems of existing automated automotive production lines' rapid switching positioning devices and high-precision rapid vehicle positioning devices for various platform models at prototyping assembly stations, improving the automation level and production efficiency of automated production lines producing different vehicle models in combination. It features modularity, intelligence, rapid switching, and high precision.

[0020] Specifically, Figure 1 This is a schematic diagram of a vehicle positioning device provided in an embodiment of this application.

[0021] like Figure 1 As shown, the vehicle positioning device 10 includes a three-axis module system 100 and an electronic control system 200.

[0022] The three-axis module system 100 includes a first to a fourth three-axis module; the first to the fourth three-axis modules are all assembled on the base plate 2; the electronic control system 200 is electrically connected to the three-axis module system 100 and is used to control the movement of the first to the fourth three-axis modules according to the preset motion parameters, so that the first to the fourth three-axis modules move to the position that matches the chassis positioning hole of the target vehicle, thereby completing the vehicle positioning.

[0023] The preset motion parameters can be user-defined movement data of the first to fourth three-axis modules, or obtained from pre-stored body chassis positioning hole coordinate data and three-axis module motion control programs corresponding to various vehicle models.

[0024] Optionally, in some embodiments, the first to fourth three-axis modules include: an X-direction slider base, a Y-direction slider base, a Z-direction slider base, and a slide rail device 4. The X-direction slider base, the Y-direction slider base, and the Z-direction slider base are each equipped with a slide rail device, and the slide rail device 4 is used to drive the X-direction slider base, the Y-direction slider base, and the Z-direction slider base to move along the X-direction, Y-direction, and Z-direction, respectively.

[0025] Specifically, vehicle positioning devices such as Figure 2 As shown, the vehicle positioning device 10 includes a first to fourth three-axis module, a base plate 1, a positioning component 2, a slider base 3, a ball bearing slide rail screw system 4 (i.e., a slide rail device), a drive assembly 5 (including a servo motor and a reducer), an electronic control system 6 (i.e., an electronic control system 200), a programmable logic controller (PLC) 7, a servo system 8, and a touch screen 9.

[0026] Each three-axis module includes three independent slider bases: an X-axis slider base, a Y-axis slider base, and a Z-axis slider base. The ball screw slide rail system 4 drives the X-axis slider base, the Y-axis slider base, and the Z-axis slider base to move smoothly left and right along the X, Y, and Z directions, respectively, providing basic motion capability for matching the chassis positioning holes of different vehicle models.

[0027] Optionally, in some embodiments, the first to fourth three-axis modules further include: a positioning element 2 and a driving component 5, wherein the positioning element 2 is mounted on the slide rail device of the Z-direction slider base and is used to insert into the chassis positioning hole of the target vehicle model to complete vehicle model positioning; the driving component 5 is connected to the slide rail device 4 for driving the slide rail device 4 to move the X-direction slider base, Y-direction slider base, Z-direction slider base and positioning element 2 along the corresponding directions, so that the positioning element 2 is inserted into the chassis positioning hole of the target vehicle model to complete vehicle model positioning.

[0028] Optionally, in some embodiments, the driving component 5 includes a servo motor and a reducer respectively arranged in the X, Y, and Z directions. The servo motor and reducer are connected to the slide rail device 4 in the corresponding directions for driving the slide rail device 4 to slide.

[0029] Positioning component 2 is mounted on the ball screw slide rail system 4 of the Z-direction slider base, and the mechanical positioning of the vehicle body is completed by inserting it into the positioning hole.

[0030] The drive component 5 provides power support for the movement of the entire module. This component consists of servo motors and reducers independently configured in the X, Y, and Z directions, which form a transmission connection with the ball screw slide rail system 4 in the corresponding direction. It drives the ball screw slide rail system 4 of the first to fourth three-axis modules to move or rise and fall in the corresponding direction until it stops at the position specified by the positioning hole of the target vehicle chassis.

[0031] Optionally, in some embodiments, the electronic control system 200 includes: a programmable controller 7, a servo drive system 8, a touch screen 9, and a program storage module. The programmable controller 7 is electrically connected to the servo drive system 8, the touch screen 9, and the program storage module. The programmable controller 7 is used to call the control program corresponding to the target vehicle model in the vehicle model program storage module and send control signals to the servo drive system 8. The servo drive system 8 is electrically connected to the drive component 5 of the three-axis module system 100 and is used to drive the drive component 5 to operate according to the control signals from the programmable controller 7. The touch screen 9 is used to realize human-machine interaction. The program storage module is used to store the coordinate data of the chassis positioning holes corresponding to various vehicle models and the control program for the movement of the three-axis module.

[0032] Specifically, the programmable controller 7 is electrically connected to the servo drive system 8, the touch screen 9, and the program storage module. The program storage module pre-stores the coordinate data of the chassis positioning holes and the motion control program of the three-axis module corresponding to various vehicle models. When a certain vehicle model needs to be produced, the operator can directly select the target vehicle model through the vehicle model switching unit of the touch screen 9, or the vehicle model automatic recognition module can automatically collect the vehicle model information.

[0033] After receiving the vehicle model instruction, the programmable controller 7 immediately calls the corresponding control program in the program storage module, calculates the motion parameters of each module by combining the positioning hole coordinate data, and sends precise control signals to the servo drive system 8.

[0034] The servo drive system 8 establishes an electrical connection with the drive component 5 of the three-axis module, converting the electrical signal output by the programmable controller 7 into the mechanical motion of the motor. Through the drive component 5, the ball screw slide rail system 4 is driven to run, ultimately achieving precise displacement of the positioning components of each module until they are completely matched with the chassis positioning hole position of the target vehicle.

[0035] Optionally, in some embodiments, the touchscreen includes a parameter setting unit for receiving X-axis, Y-axis, and Z-axis coordinate data of the first to fourth three-axis modules input by the operator; and a vehicle model switching unit for receiving the target vehicle model selected by the operator.

[0036] The touchscreen 9 features two core functional areas: a parameter setting unit and a vehicle model switching unit. The parameter setting unit provides operators with a flexible debugging channel, allowing direct input of X, Y, and Z coordinate data from the first to fourth three-axis modules to meet positioning adjustment needs under special working conditions. The vehicle model switching unit uses a visual button design, allowing operators to trigger the entire positioning process with a single click by selecting the target vehicle model (e.g., model A), greatly simplifying the operation process and reducing manual intervention costs.

[0037] Optionally, in some embodiments, the electronic control system 200 includes: a fault diagnosis module, used to monitor the operating status of the drive component 5, the servo drive system 8 and the positioning component 2, and when the positioning component 2 has an out-of-tolerance positioning deviation, or the drive component 5 or the servo drive system 8 has a fault, it issues an alarm prompt through the touch screen 9 and records the fault information.

[0038] Optionally, in some embodiments, the electronic control system 200 further includes: an automatic vehicle model recognition module, used to collect the vehicle model positioning information of the previous workstation on the automated vehicle production line, and transmit the vehicle model positioning information of the previous workstation to the programmable controller 7, and automatically start the vehicle model positioning of the next workstation after the electronic control system 200 recognizes the vehicle model positioning of the previous workstation.

[0039] Specifically, the electronic control system 200 has a built-in fault diagnosis module that monitors the operating status of the drive components, servo drive system, and positioning components in real time. When the positioning component deviates beyond tolerance (such as misalignment with the chassis positioning holes), or when the drive component fails or the servo drive system malfunctions, the module will immediately issue an audible and visual alarm via the touchscreen and automatically record key information such as the time of the fault and the type of fault, providing accurate information for subsequent maintenance.

[0040] Meanwhile, the electronic control system 200 is also equipped with an automatic vehicle model recognition module. This module collects the vehicle model positioning information from the previous workstation on the production line and transmits the relevant information to the programmable controller 7 in real time. After the previous workstation completes and confirms the vehicle model positioning, the system automatically starts the positioning process for this workstation without manual triggering, achieving seamless connection between workstations on the production line and further improving production efficiency.

[0041] Optionally, in some embodiments, it further includes: a vehicle body conveying mechanism for conveying the target vehicle body to the target location after the target vehicle body has been positioned.

[0042] Specifically, after the four positioning positions of the target vehicle chassis of the four-axis three-axis drive module are fixed, the vehicle body is transported to the workstation positioning device by the vehicle body conveying mechanism (including manual hoisting or automatic conveying line) and locked. After the vehicle body is locked, it can be used for other corresponding operations.

[0043] To facilitate understanding of the vehicle positioning device described in this application, in conjunction with Figure 2 To elaborate further.

[0044] This device is used in automated production lines for various car models in automobile manufacturing enterprises. Its main structure consists of four sets of three-axis module systems assembled on a base plate 1. The four positioning holes under the car body chassis are aligned with the positioning parts 2 of the four sets of three-axis module components, so that the car body is stably placed on the device. Then, the industrial robot is matched with the corresponding spot welding, planting welding, riveting welding, CO2 welding machine, glue application and other pre-taught trajectories to perform other operations.

[0045] Each three-axis module mainly consists of three slider bases 3 for the X, Y, and Z directions. The ball screw slide rail system 4 is assembled on the three slider bases in the Z direction. The positioning component 2 is assembled on the ball screw slide rail Z-axis system. The ball screw of the three-axis module is driven by the servo motors and reducers 5 in the three directions to move the corresponding three slider bases in the X, Y and Z directions. This determines the front-to-back, left-to-right distance and lifting height of the positioning components of the four sets of three-axis modules, so that the four positioning holes of the vehicle chassis can be placed horizontally on the positioning components of the four sets of three-axis modules. The vehicle body is placed stably, and other tools can perform other operations on the vehicle body, such as robotic spot welding and glue application.

[0046] The electronic control system 6 controls the precise movement of each module in the X, Y, and Z directions. The electronic control system 6 mainly includes a programmable logic controller (PLC) 7, a servo drive system 8, a touchscreen 9, and programs for various vehicle models programmed according to the chassis dimensions. When producing a vehicle model A, the button for model A is selected directly on the touchscreen 9. The PLC 7 receives the instructions according to the pre-programmed model A program and sends a signal to control the servo drive system. The servo drive system controls the motor and its reducer to drive the ball screw slide rail systems of the four sets of three-axis modules to move precisely in the corresponding directions or rise and fall until they stop at the positions specified by the positioning holes on the model A chassis. The four positioning positions of the chassis are then fixed. The body-in-white is then transported to the positioning device at this workstation via manual hoisting or automatic conveyor line, and locked in place. After the body is locked, it can be used for other corresponding operations.

[0047] The invention of a high-precision CNC positioning quick switching device for the production of various vehicle models is briefly described below in practical applications.

[0048] Step 1: Set the coordinate data of the four positioning holes on the new vehicle chassis.

[0049] After the device is powered on and started, the touch screen of the electrical control system displays the main screen (e.g., Figure 3 As shown), click Parameters, enter your process username and password to log in, and the vehicle selection screen will be displayed. Figure 4 As shown in the image, clicking the unused vehicle model button on this screen will display a screen showing the required data input for four sets of three axes for that vehicle model. Figure 5 As shown), based on the chassis positioning hole coordinates of the new model, calculate the data for the four modules U1 to U12 respectively, manually input them, and after confirming that they are accurate, click the save and confirm button in the upper right corner of the screen. Then return to the main screen ( Figure 3 As shown in the image, clicking the automatic positioning button will cause the four modules to move rapidly and with high precision in the X / Y / Z directions based on the data imported for the new vehicle model. Ultimately, they will align with the four positioning holes on the new vehicle model's chassis, completing the new model's positioning data setup. Theoretically, this system can set positioning hole data for N different vehicle models, enabling flexible production of N different vehicle models.

[0050] Step 2: After the device has been pre-set with chassis positioning data for multiple vehicle models, when a specific vehicle model is actually produced, the device needs to match the vehicle model's positioning holes. Typically, the vehicle model is selected manually or automatically by opening the vehicle model selection screen. Figure 4 As shown), after selecting the vehicle model to produce, return to the main screen ( Figure 3(As shown) Click "Auto Positioning". The four modules, each with three axes, control servo motors and reducers to perform rapid, high-precision movement in the X / Y / Z directions, based on the selected vehicle model. This is achieved through a programmable logic controller (PLC) and servo drive system. Ultimately, the distance and horizontal height of the four module three-axis positioning components align with the four positioning holes on the new vehicle model's chassis, completing the positioning process. Furthermore, this device can automatically identify the vehicle model at a workstation on the production line. The electrical control system collects and analyzes the vehicle model data from a workstation, automatically executing a high-precision, rapid switching of the positioning device at the next workstation. This allows for automatic adjustment of the positioning device at that workstation. After the previous workstation's vehicle model is completed, the automatic conveyor line transports the car body to the pre-positioned device, improving production cycle time and enabling simultaneous production of different vehicle models on mixed lines.

[0051] According to the vehicle positioning device proposed in this application, the electronic control system controls the movement of the first to fourth three-axis modules based on pre-set motion parameters, so that the first to fourth three-axis modules move to a position matching the chassis positioning holes of the target vehicle, thus completing the vehicle positioning. This solves the problem of rapid switching positioning devices in existing automated automotive production lines and high-precision rapid vehicle positioning devices for multiple different platform models in trial assembly stations, improving the automation level and production efficiency of automated production lines producing different vehicle models in combination. It features modularity, intelligence, rapid switching, and high precision.

[0052] Next, the vehicle positioning method proposed according to the embodiments of this application is described with reference to the accompanying drawings.

[0053] like Figure 6 As shown, the vehicle positioning method includes the following steps: In step S601, preset motion parameters are received.

[0054] In step S602, the first to fourth three-axis modules are moved according to the preset motion parameters, so that the first to fourth three-axis modules move to the position that matches the positioning hole of the target vehicle chassis, thereby completing the vehicle positioning.
