[0047] In the current vehicle production line, the movement of the chassis and the vehicle between various stations is usually realized by a slide plate or a plate chain. For the slide plate or the plate chain, a track needs to be set on the ground or a guide rail or other structures need to be set in the air above the site, and these structures all need to be constructed by civil engineering.
[0048] For different models of vehicles, the production and processing procedures required will be different, which requires changing the moving direction, start-stop position, etc. of the chassis and the vehicle between various stations. The current slide plate and plate chain structure takes a long time to reform after construction is completed, has high cost, has a long production suspension period, has poor adaptability to different models of vehicles, and has low efficiency.
[0049] Based on the above considerations, in order to alleviate the problem of low efficiency of the current vehicle production line for processing and reforming different vehicle models, the embodiments of the present application provide a vehicle production line, which sets a navigation installation station and installs a navigation device on the vehicle after the upper body and the chassis are combined, so as to guide and control the movement of the vehicle through the navigation device; the navigation device is arranged on the upper body, and the navigation installation station is arranged after the assembly station.
[0050] In such a vehicle production line, the vehicle can be driven to move along a preset processing path by the navigation device, so that the vehicle can move autonomously to various stations. In the case of changing the vehicle model, only the preset processing path needs to be changed, so that the navigation device can drive the vehicle to move along the changed processing path. This setting does not need to set the structure of civil construction, saves the slide plate, the plate chain and the corresponding civil structure, and the change of the vehicle walking path can be realized by the preset route of the navigation device, which improves the adaptability of the vehicle production line to different vehicle models and reduces the cost of the vehicle production line to adapt to different vehicle models. The navigation device is arranged on the upper body to reduce the interference of the vehicle structure itself with the navigation device in collecting environmental information, so that the navigation device can better collect environmental information and guide the movement of the vehicle.
[0051] The vehicle production line disclosed by the embodiments of the present application can be used to produce vehicles of different types and models. The vehicles can be large cars, small cars, special purpose cars, and the like. For example, according to the vehicle types, the vehicles can be sedan types, off-road types, multi-purpose vehicle (MPV) types, or other types.
[0052] To illustrate the technical solutions of the present application, the specific embodiments and drawings are described below.
[0053] Reference Figure 1 , Figure 2 The embodiments of the present application provide a vehicle production line 1000, which includes at least one assembly station 100, a combined assembly station 200, and a navigation installation station 300. The combined assembly station 200 is provided with a combined assembly device, which is used to combine a chassis 900 and an upper body 800 of a vehicle 2000. The navigation installation station 300 is provided with a navigation installation device, which is used to install a navigation device 310 on the upper body 800. The combined assembly station 200, the navigation installation station 300, and the at least one assembly station 100 are arranged along a processing path in sequence. The navigation device 310 is configured to control the vehicle 2000 to start and stop, and guide the vehicle 2000 to move along the processing path.
[0054] The chassis 900 refers to a frame structure at the bottom of the vehicle 2000 and its attached mechanical components. The chassis 900 can include a chassis frame, a suspension system, a braking system, a steering system, an electrical system, or other structures. The upper body 800 refers to a support structure that constitutes a passenger compartment. The upper body 800 can include a pillar, a roof structure, a front wall, or other structures.
[0055] The combined assembly station 200 refers to a station for combining the upper body 800 and the chassis 900. The combined assembly station 200 can be a designated space area or a space area enclosed by structural members. The combined assembly station 200 provides space for the installation of the upper body 800 on the chassis 900. Welding, screwing, and other operations of the upper body 800 and the chassis 900 can be completed in the combined assembly station 200.
[0056] The combined assembly device refers to a device provided in the combined assembly station 200 and used to combine the chassis 900 and the upper body 800. Workers can combine the chassis 900 and the upper body 800 in the combined assembly station 200 through the combined assembly device. The combined assembly device can include positioning devices, lifting devices, and the like. According to the combination method of the chassis 900 and the upper body 800, the combined assembly device can also include welding devices, bolt pre-tightening devices, and the like to assist workers in combining the chassis 900 and the upper body 800.
[0057] The assembly station 100 refers to a station in the vehicle production line 1000 for mounting various structural parts to the chassis 900 and the upper body 800. The assembly station 100 can be a set space region or a space region surrounded by structural parts. The assembly station 100 can be used to mount structural parts such as wiring harnesses, sunroofs, windows, instrument panels, seats, windshields, etc. According to the specific processing procedure corresponding to the assembly station 100, the number of assembly stations 100 can be one, two or more, so as to facilitate different processing of the vehicle 2000.
[0058] The navigation installation station 300 refers to a station in the vehicle production line 1000 for installing a navigation device 310. The navigation installation station 300 can be a set space region or a space region surrounded by structural parts. The navigation installation station 300 provides space for the navigation device 310 to be installed on the upper body 800. The navigation device 310 can be connected to the upper body 800 by clamping, screwing or other means.
[0059] The navigation device 310 refers to a device with positioning, guiding and control functions. After the navigation device 310 is installed on the vehicle 2000, the navigation device 310 can determine the position of the vehicle 2000. The navigation device 310 can also guide the vehicle 2000 to move along a preset path, and the navigation device 310 can also control the start and stop of the vehicle 2000. For example, the navigation device 310 can be a SLAM (Simultaneous Localization and Mapping) navigation device 310, which has the ability to build a map, thereby better guiding the vehicle 2000 to move along a preset path.
[0060] After the vehicle 2000 moves to the navigation installation station 300, the navigation device 310 is installed on the combined chassis 900 and upper body 800. Since the navigation device 310 can control the start and stop of the vehicle 2000, the navigation device 310 should also be in communication with the electronic control system of the vehicle 2000 to control the state of the vehicle 2000.
[0061] After the vehicle 2000 moves to the navigation installation station 300, the navigation device 310 is installed on the upper body 800. Since the navigation device 310 needs to collect environmental information around it to determine the position of the navigation device 310 and achieve positioning, placing the navigation device 310 on the upper body 800 can reduce the obstruction of the navigation device 310 by the structures on the chassis 900 and the upper body 800, and reduce the interference of the navigation device 310 by the structures on the chassis 900 and the upper body 800, thereby improving the accuracy of the navigation device 310.
[0062] Meanwhile, the navigation device 310 is installed on the upper body 800 more conveniently, without the need of lifting the chassis 900 or the upper body 800 for installation, and the space where the upper body 800 is located is more open, facilitating the installation of the navigation device 310 by the staff or installation equipment.
[0063] The machining path refers to the arrangement path of each station in the vehicle production line 1000, and is also the path along which the chassis 900 or the vehicle 2000 moves and is processed. The machining path can be a virtual path set in advance and pre-set in the navigation device 310. The machining path can be different according to different vehicle models. In this case, only the machining path needs to be changed for different vehicle models, without the need of disassembling, modifying, installing, etc. in structure.
[0064] The assembly station 200, the navigation installation station 300 and the at least one assembly station 100 are arranged in sequence along the machining path, that is, after the chassis 900 and the upper body 800 are assembled at the assembly station 200, the chassis 900 and the upper body 800 can pass through the navigation installation station 300 and the assembly station 100 in sequence.
[0065] It can be understood that the vehicle production line 1000 can further include other stations between the assembly station 200, the navigation installation station 300 and the assembly station 100. The vehicle production line 1000 can further include other stations before the assembly station 200 and after the assembly station 100.
[0066] In the vehicle production line 1000 provided in the embodiment, the chassis 900 and the upper body 800 are first assembled at the assembly station 200. Then, the assembled vehicle 2000 is transported to the navigation installation station 300, and the navigation device 310 is installed on the upper body 800 at the navigation installation station 300. Then, the navigation device 310 controls the vehicle 2000 to leave the navigation installation station and pass through one or more assembly stations 100 along the machining path, so as to facilitate the assembly and processing of the vehicle 2000.
[0067] In this embodiment, the navigation installation station 300 is arranged to facilitate the installation of the navigation device 310 on the vehicle 2000 and control the vehicle 2000 to move along the processing path through the navigation device 310, so that the vehicle 2000 can move between various stations by itself through the navigation device 310, saving the slide plate, plate chain and corresponding civil structure, and the change of the walking path of the vehicle 2000 can be realized through the preset route of the navigation device 310, improving the adaptation ability of the vehicle production line 1000 to different vehicle models and reducing the cost of adapting the vehicle production line 1000 to different vehicle models; the navigation device 310 station is arranged downstream of the assembly station 200, so that the navigation device 310 can be installed on the upper body 800; the navigation device 310 is arranged on the upper body 800 to reduce the interference of the structure of the vehicle 2000 itself with the navigation device 310 in collecting environmental information, so that the navigation device 310 can better collect environmental information and guide the vehicle 2000 to move.
[0068] Reference Figure 1 , Figure 2 In some embodiments, the vehicle production line 1000 further comprises a navigation disassembly station 400, and the navigation disassembly station 400 is provided with a navigation disassembly device for disassembling the navigation device 310 from the upper body 800; the navigation disassembly station 400 is located downstream of at least one assembly station 100.
[0069] The navigation disassembly station 400 refers to a station in the vehicle production line 1000 for installing the navigation device 310, and the navigation disassembly station 400 can be a set space area or a space area surrounded by structural members; the navigation disassembly station 400 is used to provide space for disassembling the navigation device 310 from the upper body 800.
[0070] The navigation disassembly station 400 is provided with a navigation disassembly device to facilitate the worker to disassemble the navigation device 310 from the upper body 800, and the navigation disassembly device can also be an automatic device to automatically disassemble the navigation device 310 from the upper body 800 without the operation of the worker.
[0071] The navigation disassembly station 400 is located downstream of at least one assembly station 100, in the case of only one assembly station 100, the navigation disassembly station 400 is located downstream of the assembly station 100, and in the case of multiple assembly stations 100, the navigation disassembly station 400 can be located downstream of the last assembly station 100, or the navigation disassembly station 400 can be located downstream of any other assembly station 100.
[0072] The navigation dismounting station 400 is located downstream of the assembly station 100, that is, after the chassis 900 and the upper body 800 are assembled and processed by the assembly station 100, the navigation device 310 can be dismounted from the upper body 800, and the vehicle 2000 can be conveniently subjected to subsequent processing procedures, such as detection and delivery.
[0073] After the vehicle 2000 moves to the navigation dismounting station 400, the navigation device 310 is dismounted from the assembled chassis 900 and the upper body 800, and the communication connection between the navigation device 310 and the vehicle 2000 is also cut off.
[0074] The dismounted navigation device 310 can be transported to the navigation mounting station 300 to be mounted on other vehicles 2000.
[0075] In this embodiment, the navigation dismounting station 400 is provided to facilitate the reuse of the navigation device 310, and to reduce the negative effects of the navigation device 310 on the vehicle 2000.
[0076] Reference Figure 2 In some embodiments, the vehicle production line 1000 further includes a transfer device for transporting the navigation device 310 from the navigation dismounting station 400 to the navigation mounting station 300.
[0077] The transfer device refers to a structure in the vehicle production line 1000 for transporting the navigation device 310. The transfer device can include a conveyor belt, a trolley, a robot, or other structures capable of transporting the navigation device 310.
[0078] One end of the transfer device can be located on one side of the navigation dismounting station 400, so that the transfer device can obtain the navigation device 310 dismounted from the vehicle 2000 from the navigation dismounting station 400; the other end of the transfer device can also be located at other positions and obtain the navigation device 310 dismounted from the vehicle 2000 through an intermediate structure.
[0079] The other end of the transfer device can extend to one side of the navigation mounting station 300, so that the transfer device can transport the navigation device 310 to the navigation mounting station 300; the other end of the transfer device can also be located at other positions and transport the navigation device 310 to the navigation mounting station 300 through an intermediate structure.
[0080] In this embodiment, the transfer device is provided, and the navigation device 310 dismounted from the navigation dismounting station 400 is transported to the navigation mounting station 300 through the transfer device, so that the navigation device 310 can be recycled, thereby reducing the number of navigation devices 310 required by the vehicle production line 1000 and reducing the use cost.
[0081] ReferenceFigure 2 In some embodiments, during the movement of the vehicle 2000, the navigation device 310 is configured to collect and store the position information of the corresponding vehicle 2000; the initialization device is further provided in the navigation installation station 300, and the initialization device is configured to reset the navigation path control information in the navigation device 310.
[0082] In the case that the vehicle production line 1000 comprises the assembly station 200, the navigation installation station 300, at least one assembly station 100 and the navigation dismounting station 400, the movement process of the vehicle 2000 refers to the process that the vehicle 2000 moves from the navigation installation station 300 to the navigation dismounting station 400; in the case that the vehicle production line 1000 comprises the assembly station 200, the navigation installation station 300 and at least one assembly station 100, the movement process of the vehicle 2000 refers to the process that the vehicle 2000 moves from the navigation installation station 300 to the last assembly station 100.
[0083] During the movement of the vehicle 2000, the navigation device 310 can collect and store the position information of the vehicle 2000, and according to the position information and the processing path, the navigation device 310 can guide and control the vehicle 2000 to move along the processing path, and the navigation device 310 can also control the vehicle 2000 to leave the navigation installation station 300 and stay in the assembly stations 100 and the navigation dismounting station 400.
[0084] The initialization device is a device capable of initializing the navigation device 310, and the initialization device can be a computer or other devices capable of initialization.
[0085] After the navigation device 310 is dismounted from the navigation dismounting station 400, the position information of the previous vehicle 2000 is still stored in the navigation device 310, and the navigation device 310 can even be in communication connection with the previous vehicle 2000; at this time, if the navigation device 310 is installed on another vehicle 2000, the information of the navigation device 310 and the vehicle 2000 will not correspond, thereby affecting the normal navigation of the navigation device 310 to the vehicle 2000. Accordingly, the initialization of the navigation device 310 refers to the action of resetting the navigation path control information in the navigation device 310, and the main information of the previous vehicle 2000 in the navigation device 310 is initialized, for example, the communication connection state with the previous vehicle 2000 is disconnected, and the position information of the previous vehicle 2000 is cleared; it can be understood that after the initialization of the navigation device 310, the navigation device 310 still has the functions of collecting the information around the vehicle 2000, guiding the vehicle 2000 to move along the processing path, controlling the vehicle 2000 to start and stop, etc., that is, the initialization of the navigation device 310 will not cause the failure of the functions of the navigation device 310.
[0086] In the case that the navigation device 310 detached at the navigation dismounting station 400 is transported to or near the navigation mounting station 300, the navigation device 310 will first undergo the initialization process of the initialization device, and the navigation device 310 after the initialization process will be mounted on the vehicle 2000 in the navigation mounting station 300.
[0087] In this embodiment, the initialization device is arranged in the navigation mounting station 300 to initialize the navigation device 310, so as to reduce the interference of the data remaining in the navigation device 310 on the guidance of the corresponding vehicle 2000 at present, and improve the accuracy of the navigation device 310 guiding the movement of the vehicle 2000.
[0088] Reference Figure 3 In some embodiments, the vehicle production line 1000 further comprises an environment safety monitoring device 710 configured to form a first safety signal in the case that there is an intruder on the processing path; the navigation device 310 is configured to form a second safety signal in the case that there is an intruder on the travel route of the vehicle 2000; the vehicle production line 1000 further comprises a control device 720 configured to acquire the first safety signal and / or the second safety signal and send a control signal to the navigation device 310.
[0089] The environment safety monitoring device 710 refers to a device in the vehicle production line 1000 for collecting whether there is an intruder on the processing path, and the environment safety monitoring device 710 can include one or more cameras, radars or other information collection devices; wherein the intruder refers to a substance overlapping with the processing path, and the intruder can be a person, a mechanical hand or other substances.

[0091] The first safety signal refers to a signal that the environment safety monitoring device 710 can form after collecting that there is an intruder on the processing path, and the first safety signal can be an electrical signal, an optical signal or other forms of signals; the environment safety monitoring device 710 forming the first safety signal means that there is an intruder on the movement path of the vehicle 2000, and the intruder will hinder the movement of the vehicle 2000 along the processing path, and the collision between the vehicle 2000 and the intruder can cause damage to the vehicle 2000 and the intruder, thereby causing safety problems.
[0092] The navigation device 310 can collect the environmental information around the vehicle 2000, that is, the navigation device 310 can also collect whether there is an intruder on the machining path. Accordingly, the second safety signal is a signal that the navigation device 310 can form after collecting that there is an intruder on the machining path. The second safety signal can be an electrical signal, an optical signal, or other forms of signals. The formation of the second safety signal by the navigation device 310 means that there is an intruder on the moving path of the vehicle 2000, and the intruder will hinder the movement of the vehicle 2000 along the machining path. The collision between the vehicle 2000 and the intruder can cause damage to the vehicle 2000 and the intruder, thereby causing a safety problem.
[0093] The control device 720 refers to a device in the vehicle production line 1000 for sending information to the navigation device 310 to control the state of the vehicle 2000. The control device 720 can include a computer, a programmable logic controller (PLC), a distributed control system (DCS), or other devices.
[0094] The control device 720 can receive the first safety signal and / or the second safety signal. Since the formation of the first safety signal and the second safety signal both means that there is a safety hazard, the control device can be configured to receive only the first safety signal or the second safety signal, or to receive both the first safety signal and the second safety signal. In the case where the control device 720 receives any one of the first safety signal and the second safety signal, the control device 720 can respond to the received signal and form a control signal. The control device 720 can also send the control signal to the navigation device 310, so that the navigation device 310 can control the state of the vehicle 2000, for example, to stop the vehicle 2000, so that the worker can move the intruder out of the machining path.
[0095] In this embodiment, the environmental safety monitoring device 710 is provided to monitor whether there is an intruder on the machining path and form the first safety signal. The control device 720 is provided and can determine whether the machining path is safe through the first safety signal. The control device 720 can send a control signal to the navigation device 310, so that the navigation device 310 can confirm whether the machining path is safe through the information collected by itself, and also can confirm whether the machining path is safe through the control signal. The safety performance of the navigation device 310 in controlling the movement of the vehicle 2000 is improved.

[0106] The time for the navigation device 310 to control the vehicle 2000 to stay in the final assembly station 120 can be a preset time; or the navigation device 310 can only control the vehicle 2000 to stop in the final assembly station 120, and the action of the navigation device 310 to control the vehicle 2000 to leave the final assembly station 120 can be realized by the worker.
[0107] In the embodiment, the assembly station 100 includes the final assembly station 120, so that the worker can perform the final assembly processing on the vehicle 2000.

[0109] The detection station 500 refers to a station in the vehicle production line 1000 for detecting the vehicle 2000, and the detection station 500 can be a space region set or a space region surrounded by structural members; in the detection station 500, the vehicle 2000 can be subjected to appearance detection, electrical detection or other detection operations, and the vehicle 2000 that passes the detection in the detection station 500 can be reported and delivered.
[0110] The operation in the detection station 500 can be only processed by the worker, or a detection device can be arranged to assist the worker to perform the detection processing, and an automatic detection device can also be arranged to realize the detection processing only by the detection device.
[0111] The detection station 500 is located downstream of the navigation disassembly station 400, that is, after the navigation device 310 is disassembled, the vehicle 2000 will move to the detection station 500; the vehicle 2000 can be driven to the detection station 500 by the worker, or can be transported to the detection station 500 by other means.
[0112] Since the detection station 500 is located downstream of the navigation dismounting station 400, the navigation device 310 needs to be detected in the detection station 500 to reduce the risk of the vehicle 2000 carrying the navigation device 310 after being offline.
