[0028] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0029] First, the professional terms appearing in this article are explained to facilitate technical personnel in this field to understand this solution:

[0030] KIT supply: According to the specific sequence plan of the production line, it sorts the parts into complete sets in advance according to the vehicle model requirements and places them in specific containers. Then, through conveying equipment, these parts are synchronously transported to the side of the production line to ensure that the operators can get the required parts at the nearest distance.

[0031] Cart docking: Cart docking is an important part of the logistics, manufacturing and production process. It involves the process of transporting materials, parts or products from one location or workstation to another through a supply cart. It includes: Direct docking: The supply cart directly stops at the target location, and the operator or automated equipment unloads the materials, parts or products from the car; Transfer docking: The supply cart first transports the materials, parts or products to a transfer station or buffer zone, and then other transportation tools or equipment carry out secondary handling. Automatic docking: In a highly automated production environment, the supply cart can automatically dock with the production line or other equipment, and complete the transportation and unloading of materials without human intervention.

[0032] AGV: Automated Guided Vehicle, commonly known as an automated guided vehicle. It is a transport vehicle equipped with an electromagnetic or optical automatic guidance device that can travel along a specified guide path and has safety protection and various transfer functions. In industrial applications, AGVs are usually used in scenarios such as material handling and production line distribution, which can significantly improve production efficiency, reduce costs, and enhance the accuracy and flexibility of operations.

[0033] The embodiment of the present application provides a segmented intelligent production line for commercial vehicle chassis assembly, which can solve the technical problems existing in the prior art, such as unreasonable layout of traditional commercial vehicle chassis production lines, low production line fault tolerance, and limited operation, especially when performing bottom operations on new energy vehicles, resulting in cumbersome assembly processes.

[0034] The segmented commercial vehicle chassis assembly intelligent production line in the present application includes a main line component and a transfer component. The main line component is arranged on the ground for the transmission of the chassis to be installed. The operators are at specific workstations to carry out the assembly line forward operation. The main line component is divided into three general assembly sections according to the different assembly areas of the chassis to be installed. The head end or the tail end of each general assembly section is connected to form a curved whole, which can greatly reduce the space occupied by the main line component and facilitate the transmission of the chassis to be installed and materials. At the same time, the division of labor of each general assembly section is different, so the overall fault tolerance of the main line component can also be improved. The transfer component is arranged above the main line component and has the same linear shape as the main line component. It can carry out the online, hoisting and transportation of the chassis to be installed according to the assembly progress of the chassis to be installed, and the transfer component can flexibly adjust its clamping height according to the assembly progress of the chassis to be installed to reserve assembly space for the bottom of the chassis to be installed. The overall versatility of the production line is high and can meet the assembly requirements of the frame chassis of most models.

[0035] Specifically, Figure 1 A schematic diagram of a segmented commercial vehicle chassis assembly intelligent production line layout provided in an embodiment of the present application is shown in FIG. Figure 1 As shown, the main line assembly includes a conductor unit and a transmission unit located on the conductor unit. The conductor unit includes a first assembly section 1 and a second assembly section 2 connected end to end with the first assembly section 1 to form a ring. A third assembly section 3 is provided on the side of the second assembly section 2 away from the first assembly section 1, and the head end of the third assembly section 3 is connected to the tail end of the second assembly section 2.

[0036] The chassis to be installed is first hoisted to the head end of the first assembly section 1 by the transfer assembly. The first assembly section 1 is used for the reverse installation of the chassis to be installed. The main operations include: pipeline laying, urea pot assembly, front and rear axle installation, post-processing assembly, flipping operation, etc. Then the chassis to be installed is transferred to the head end of the second assembly section 2. The second assembly section 2 is mainly used for urea water pipe assembly and connection, fuel pipe assembly and connection, engine installation and accessory connection, gantry beam, air filter intake accessory connection, all-in-one, high-pressure box assembly and related wiring harness connection, side battery assembly, etc. Finally, the chassis to be installed is transferred from the tail end of the second assembly section 2 to the head end of the third assembly section 3 by the transfer assembly.

[0037] Among them, the third section 3 of the general assembly is equipped with an aerial work area 301, an online installation area 302 and a product lifting and separation area from the head end to the tail end. The aerial work area 301 is mainly used for bottom operations such as exhaust pipe connection and fixation, bottom battery installation, and wiring harness connection and fixation. The transfer component can adjust its own height. When the transfer component clamps the chassis to be installed and moves to the aerial work area 301 at the head end of the third section 3 of the general assembly, the transfer component clamps the chassis to be installed and lowers it to a certain height to facilitate the staff to perform bottom operations on the chassis to be installed, and then the transfer component The chassis to be installed is clamped and continues to move forward to the online installation area 302, and the height is lowered until the chassis to be installed is placed on the online installation area 302. The transfer assembly is separated from the chassis to be installed. The online installation area 302 is mainly used by workers to carry out operations such as cab installation and accessory connection, fuel tank installation, tire installation, and back battery installation. Finally, the chassis to be installed continues to be transferred to the product lifting and separation area at the tail end of the third assembly section 3. The product lifting and separation area can lift the installed chassis to be installed to separate it from the third assembly section 3 and carry out offline work.

[0038] For further information, see Figure 1 The transmission unit includes a first AGV 4 for circulating between the first assembly section 1 and the second assembly section 2, and a second AGV 5 for circulating between the online installation area 302 and the product lifting and separation area. The transmission unit is used to carry the chassis to be installed and translate along the transmission path of the main line component. Combined with the above description, the first assembly section 1 and the second assembly section 2 are connected end to end. Therefore, the first AGV 4 carries the chassis to be installed and passes through the first assembly section 1 and the second assembly section 2 in sequence. Finally, at the end of the second assembly section 2, the transfer component will be The installed chassis is hoisted to the head end of the third assembly section 3, and the first AGV4 is automatically translated to the head end of the first assembly section 1 to carry the next chassis to be installed. The initial position of the second AGV5 is located in the online installation area 302. A circular track is provided at the online installation area 302 and the product lifting and separation area, so that the second AGV5 can carry the chassis to be installed and translate cyclically between the online installation area 302 and the product lifting and separation area. When the chassis to be installed is separated from the production line, the second AGV5 returns to the online installation area 302 to carry the next chassis to be installed.

[0039] For further information, see Figure 1 The transfer component includes an aerial track 6 located above the main line component and adapted to the linear shape of the conductor unit, and a clamping unit 7 located on the aerial track 6 and capable of adjusting its own height. Combined with the above description, the transmission trajectory of the transmission unit along the conductor unit is an S-shaped curve, and the aerial track 6 is consistent with the bending shape of the conductor unit and is also S-shaped, so that its transfer range covers the entire transportation area of ​​the transmission unit. The clamping unit 7 can move along the aerial track 6 under the control of the upper control system. It is mainly used to clamp the chassis to be installed, and can flexibly adjust its own height according to the assembly area of ​​the chassis to be installed on different assembly sections.

[0040] The segmented commercial vehicle chassis assembly intelligent production line in the present application can transport the chassis to be installed in different directions according to the installation progress of the chassis by setting a segmented wire unit and a first AGV4 and a second AGV5 located on the wire unit. Each installation section has high independent working performance, which greatly improves the fault tolerance of the production line. The bending posture of the main line component can reduce the overall occupied space of the production line and increase the equipment installation space between each assembly section of the production line. By setting a transfer component with adjustable height, the chassis to be installed can be put on line, hoisted and transferred. In conjunction with the aerial working area 301 located on the third assembly section 3, a stable frame bottom installation space can be provided for the chassis to be installed, which is suitable for the installation of vehicles with various power systems. By setting a product lifting and separation area at the tail end of the third assembly section 3, the chassis to be installed can be automatically taken off line. The entire production line has a reasonable layout and high automation performance, which greatly improves the assembly efficiency of the chassis to be installed.

[0041] Furthermore, Figure 2 A top view of the main line components in a segmented commercial vehicle chassis assembly intelligent production line provided in an embodiment of the present application, such as Figure 2 As shown, the main line assembly also includes a KIT supply unit, which includes a line-following trolley 8 for moving synchronously with the first AGV 4 and a plurality of trolley docking units, which are respectively located at the head and tail ends of the first assembly section 1 and the head and tail ends of the second assembly section 2.

[0042] The on-line trolley 8 carries the installation materials and moves on the line with the first AGV 4 to ensure that the materials can be accurately transported to the designated location according to the production process or logistics requirements. The main structure of the on-line trolley 8 is usually made of steel or other strong materials to ensure its carrying capacity and stability, which can reduce manual intervention and improve production efficiency.

[0043] The trolley docking unit is mainly used to transport the line-following trolley 8 and to carry out the on-line and off-line work of the line-following trolley 8 between the first assembly section 1 and the second assembly section 2, so as to improve the automation and transmission convenience of the overall structure. The line-following trolley 8 first goes online through the trolley docking unit located at the head end of the first assembly section 1, and moves with the first AGV4 to the trolley docking unit located at the tail end of the first assembly section 1 to go offline. Subsequently, the line-following trolley 8 is towed to the head end of the second assembly section 2 by the ground traction equipment and goes online through the trolley docking unit located at the head end of the second assembly section 2. At this time, the first AGV4 automatically translates to the second assembly section 2. Finally, the line-following trolley 8 moves with the first AGV4 to the trolley docking unit located at the tail end of the second assembly section 2 to go offline, and the materials of the third assembly section 3 are arrived by the transfer component conveyor line. Therefore, the third assembly section 3 does not need to be equipped with a trolley docking unit and a line-following trolley 8.

[0044] Furthermore, the main line assembly in the present application includes multiple groups of trolley docking units, each trolley docking unit includes two oppositely arranged docking devices 9. Taking the first assembly section 1 as an example, two docking devices 9 are arranged at both ends of the first assembly section 1, and the two docking devices 9 located at the same end are arranged oppositely along the width direction of the first assembly section 1. In a possible embodiment, the main line assembly in the present application is provided with two following-line trolleys 8, and each following-line trolley 8 moves between the docking devices 9 on the same side of the first assembly section 1 and the second assembly section 2.

[0045] The docking device 9 includes a variety of structures and docking methods in actual use, but basically includes a conveying system for realizing automatic conveyance of the supply line trolley 8, a positioning system for ensuring that the supply line trolley 8 can accurately dock at the designated position during the docking process, and a control system for the operation control and status monitoring of the entire docking device 9. The docking device 9 and the line trolley 8 cooperate in going up and down the line, which is an existing common means, and the specific setting method and setting form will not be elaborated here.

[0046] Furthermore, Figure 3 A front view of the first assembly section 1 and the second assembly section 2 in a segmented commercial vehicle chassis assembly intelligent production line provided in an embodiment of the present application, as shown in FIG. Figure 3 As shown, both the first assembly section 1 and the second assembly section 2 include a ground magnetic track 10, and the ground magnetic track 10 of the first assembly section 1 and the ground magnetic track 10 of the second assembly section 2 are connected end to end to form a ring, and the first AGV 4 circulates between the two ground magnetic tracks 10. In a possible implementation, the first AGV 4 is a large flat-plate AGV, which is a complete plate-like structure. The ground magnetic track 10 provides a track foundation for the operation of the large flat-plate AGV, and the track material is usually selected from wear-resistant and corrosion-resistant metal materials to withstand the operation and load of the large flat-plate AGV.

[0047] For the convenience of description, the ground magnetic track 10 of the first assembly section 1 is referred to as the first track, and the ground magnetic track 10 of the second assembly section 2 is referred to as the second track. The first track and the second track are connected end to end. In the initial state, the large flat-panel AGV is located at the head end of the first track, and the chassis to be installed is placed on the large flat-panel AGV through the transfer assembly. Under the control of the upper control system, the large flat-panel AGV walks to the tail end of the second track, and then the transfer assembly lifts the chassis to be installed to the aerial working area 301 at the head end of the third assembly section 3, and the large flat-panel AGV moves horizontally back to the head end of the first track to assemble the next chassis to be installed.

[0048] Furthermore, Figure 4 A top view of a ground double-track track 303 in a segmented commercial vehicle chassis assembly intelligent production line provided in an embodiment of the present application, as shown in FIG. Figure 4As shown, the third assembly section 3 includes a ground double-track track 303, and the ground double-track track 303 includes two monorails that are spaced apart and connected end to end to form a ring. The two monorails are arranged in parallel and maintain a certain distance to form a stable running track to ensure the stable circulation operation of the second AGV 5 on the ground double-track track 303. The monorail is usually made of high-strength, wear-resistant and corrosion-resistant metal materials to withstand the weight of the second AGV 5 and its load and the dynamic stress during transportation.

[0049] In combination with the above description, the second AGV5 is configured to perform a circular motion along the ground double-track track 303. In the initial state, the second AGV5 is located on one of the monorails of the online installation area 302 of the third section 3 of the general assembly, and circulates between the online installation area 302 and the product lifting and separation area according to the installation progress of the chassis to be installed. After the second AGV5 carries the chassis to be installed and transfers it to the product lifting and separation area, the product lifting and separation area rises to a certain height to allow the chassis to be installed to separate from the second AGV5. The second AGV5 returns to the online installation area 302 along the other monorail to carry the next chassis to be installed.

[0050] For further information, see Figure 2 The product lifting and disengagement area includes a lifting platform 11 located at the tail end of the ground double-track track 303. The product lifting and disengagement area is a specially designed area for achieving stable lifting and disengagement operations of the chassis to be installed. This area is located at the head and tail connection ends of the two monorails, so that after the second AGV5 transports the chassis to be installed to the tail end of the third assembly section 3, the product is smoothly lifted from the second AGV5 by the lifting platform 11, so that the chassis to be installed is separated from the second AGV5. Under normal conditions, the top horizontal height of the lifting platform 11 is not higher than the horizontal height of the ground double-track track 303. In a possible implementation, in order to ensure the safety and aesthetics of the production line, in the non-raised state, the top horizontal height of the lifting platform 11 is the same as the horizontal height of the ground double-track track 303.

[0051] The jacking platform 11 is usually different according to its application scenario and design requirements. In a possible implementation of the present application, the jacking platform 11 includes a platform infrastructure, a jacking mechanism and a control system, wherein the platform infrastructure is the supporting part of the jacking platform 11, which is usually made of solid steel or other high-strength materials. It is responsible for bearing the entire weight of the platform and the weight of the object being jacked, ensuring the stability and safety of the platform. The jacking mechanism is the core part of the jacking platform 11, which is used to realize the lifting function of the platform. According to different driving modes, the jacking mechanism can be divided into multiple types, such as hydraulic, pneumatic, mechanical, etc. The control system is used to control the lifting operation of the jacking platform 11 to ensure the stability and safety of the platform. It usually includes an electrical control part and a hydraulic control part. The electrical control part is responsible for receiving operation instructions, controlling the start and stop and steering of the motor, etc., and the hydraulic control part is responsible for controlling the extension and pressure of the hydraulic cylinder, etc. The jacking platform 11 is often used in the prior art. The above is only an example, and the specific structure and jacking method are not specifically limited in this application.

[0052] Furthermore, the lifting platform 11 is located between the two monorails. Combined with the above description, the ground double-track track 303 includes two monorails arranged at intervals. Therefore, when the second AGV5 transports the chassis to be installed to the product lifting and separation area, the lifting platform 11 can quickly and smoothly lift the chassis to be installed from the second AGV5 without any interference with the second AGV5, ensuring that the second AGV5 and the lifting platform 11 can coexist harmoniously and avoid any potential conflicts. This layout not only improves production efficiency, but also ensures the safety and reliability of the operation process.

[0053] Furthermore, Figure 5 A schematic diagram of 6 zones in the middle of an aerial track of a segmented commercial vehicle chassis assembly intelligent production line provided in an embodiment of the present application is shown as follows: Figure 5As shown, the aerial track 6 includes a product on-line area 601 located above the head end of the first assembly stage 1 and a second-transfer and third-transfer area 602 located above the connection between the tail end of the second assembly stage 2 and the head end of the third assembly stage 3. The aerial track 6 is an integral track line. The clamping unit 7 moves along the aerial track 6 above the main line assembly to clamp the chassis to be installed for corresponding on-line, hoisting and transfer work. In the product on-line area 601, the clamping unit 7 descends and clamps the chassis to be installed to clamp the chassis to be installed on the large flat-plate AGV located at the head end of the first assembly stage 1. Then the clamping unit 7 moves with the large flat-plate AGV to the product on-line area 601. The second-to-third transfer area 602 above the connection between the tail end of the second section 2 and the head end of the third section 3 of the final assembly is used to transfer the chassis to be installed from the large flat-panel AGV to the aerial work area 301 at the head end of the third section 3 of the final assembly. In this area, the clamping unit 7 maintains a certain height to facilitate the staff to perform related operations on the chassis to be installed. Then the clamping unit 7 clamps the chassis to be installed and continues to move forward to the online installation area 302, and places the chassis to be installed on the second AGV 5 located in the online installation area 302. Finally, the clamping unit 7 moves along the aerial track 6 to the head end of the first section 1 of the final assembly to facilitate the lifting and transfer of the next chassis to be installed.

[0054] Furthermore, Figure 6 A schematic diagram of the structure of a clamping unit 7 in a segmented commercial vehicle chassis assembly intelligent production line provided in an embodiment of the present application is shown in FIG. Figure 6 As shown, the clamping unit 7 includes an elevator 701 connected to the aerial track 6 and a clamping claw 702 located at the bottom of the elevator 701. The elevator 701 is an important part of the clamping unit 7, which is responsible for lifting and lowering the clamping claw 702 and the chassis to be installed in the vertical direction. In a possible embodiment, the elevator 701 is usually driven by electric, hydraulic or pneumatic means, and has the characteristics of strong structure, stable operation, and precise positioning. The clamping claw 702 is another key component of the clamping unit 7, which is responsible for grabbing, transporting or positioning the chassis to be installed. In a possible embodiment, the clamping claw 702 is composed of a clamping arm, a clamping force adjustment device, and a sensor. The clamping arm is used to directly grab the chassis to be installed; the clamping force adjustment device can adjust the size of the clamping force according to the weight and material of the chassis to be installed; the sensor is used to monitor the state of the clamping claw 702 and the position of the object in real time to ensure the safety and accuracy of the handling process. The above is only an example, and the specific setting structure can be multiple, and no specific limitation is made in this application.

[0055] The segmented commercial vehicle chassis assembly intelligent production line in the present application divides the main line components into segments, and each installation segment is used to install different areas of the chassis to be installed without interfering with each other, thereby effectively improving the overall fault tolerance of the production line. In conjunction with the aerial track 6 and the clamping unit 7 that are consistent with the linear shape of the conductor unit, the aerial track 6 is divided into regions to improve the online and transportation work of the chassis to be installed between different installation segments. An aerial installation area is provided at the head end of the third assembly section 3. In conjunction with the clamping height of the clamping unit 7, it can ensure that the chassis to be installed is at a certain height to facilitate the staff to carry out the installation work at the bottom of the chassis to be installed. The product lifting and separation area at the tail end of the third assembly section 3 can lift up the assembled chassis to be installed and realize automatic offline. The overall production line has strong versatility and can meet the assembly work of chassis to be installed for vehicles with different power systems such as fuel vehicles and new energy vehicles. In conjunction with the use of KIT supply units to collect and distribute materials on the vehicle, one vehicle and one collection is realized, which helps on-site 5S management.
