[0058] In the present application, the phrase "embodiment" means that the specific features, structures or characteristics described in connection with the embodiment can be included in at least one embodiment of the present application. The appearance of this phrase at various places in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment to other embodiments.

[0060] In the present application, the term "and / or" is only a description of the association relationship between the associated objects, which means that there can be three kinds of relationships, for example, A and / or B can represent the following three cases: A exists alone, A and B exist together, and B exists alone. In addition, the character " / " in the present application generally represents an "or" relationship between the front and rear associated objects.

[0061] In the embodiments of the present application, the same reference signs represent the same components, and for the sake of brevity, detailed description of the same components is omitted in different embodiments. It should be understood that the thickness, length, width and other dimensions of various components in the embodiments of the present application shown in the drawings, and the overall thickness, length, width and other dimensions of the integrated device are only exemplary and should not constitute any limitation on the present application.

[0062] In the description of the present application, it should be understood that the orientations or positional relationships indicated by the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like are based on the orientations or positional relationships shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and therefore cannot be understood as indicating or implying that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the present application.

[0063] In the description of the present application, the first feature "above" or "below" the second feature can include direct contact between the first and second features, or can include indirect contact between the first and second features through another feature therebetween.

[0064] In the description of the present application, the first feature "above", "above" and "above" the second feature includes the first feature directly above and obliquely above the second feature, or only indicates that the first feature is higher in horizontal height than the second feature.

[0065] "Multiple" appearing in the present application means two or more (including two).

[0066] In the related art, a conventional integrated body is composed of an upper body, a lower body and an opening and closing member to form a body-in-white for process flow before entering the assembly workshop, and the process steps before entering the assembly workshop include at least pre-treatment, electrophoresis, electrophoresis drying, body sealing, damping pad installation (or LASD (water-based sprayable damping material) spraying), UBS sealing (chassis weld sealing and glue coating), PVC spraying (anti-collision paint, PVC glue, stone-proof paint spraying), sealing glue drying, topcoat spraying (including primer, metallic paint, transparent paint, varnish, etc.), topcoat drying, finishing, wax injection, etc.

[0067] That is, the body-in-white entering the assembly workshop needs to complete all the above process steps in sequence.

[0068] However, the existing body-in-white fixing support points are different from the support points of the non-integrated upper body of the present application, and the existing body-in-white carriers and lifting devices cannot be adapted. At the same time, during the process of transferring the existing body-in-white between the above-mentioned multiple process steps, it may be necessary to transport by carrier at some process steps, and to transport by lifting device at some process steps. Therefore, during the process of transferring, there is a pry changing process, which causes the traditional body-in-white and the non-integrated upper body of the present application to be unable to be produced in mixed lines, and there is a line passing problem.

[0069] Further, the existing body-in-white needs to be sealed, LASD sprayed, bottom coated, and cover installed during the sealing process. However, the non-integrated upper body of the present application is constructed as two sub-assemblies with the integrated intelligent chassis, and is further assembled into a complete vehicle body. The non-integrated upper body does not need to perform the above-mentioned internal sealing and bottom sealing process steps. If the non-integrated upper body also passes through the above-mentioned process steps during the process of transferring, the production efficiency will be reduced, and the production rhythm will be affected.

[0070] The non-integrated upper body and the integrated intelligent chassis are two sub-assemblies that are assembled into a vehicle body and can be transferred to an assembly workshop for assembly. During the process of transferring, the process steps performed on the integrated intelligent chassis, such as internal sealing, LASD spraying, bottom coating, and cover installation, can be omitted, thereby simplifying the number of process steps of the non-integrated upper body, reducing energy consumption, and reducing the demand for process space to reduce costs.

[0071] Based on this, the present application proposes a non-integrated upper body tooling line. The tooling line of the present application solves the technical problem that the existing tooling equipment cannot be compatible with the non-integrated upper body of the present application, and provides a feasible solution for the process transfer of the non-integrated upper body. The non-integrated upper body is divided into multiple components such as doors, covers, side walls, and fenders. The multiple components are fixed on corresponding toolings by lifting, and fewer process steps are performed. During the process of transferring, there is no need to switch toolings (such as switching from a lifting device to a carrier, or switching from one carrier to another carrier), and there is no need to perform the above-mentioned multiple bottom coating processes. The tooling is already lifted by the lifting device, and there is no need to perform the pry changing operation. Compared with traditional workshops, the demand for process space is lower, and the space sizes of the multiple components are also much smaller than those of traditional body-in-whites. The space occupied by each component is smaller. When the tooling line is loaded into the corresponding workshop, the demand for the space size of the process equipment, the floor area of the workshop, and the height of the lifting frame is also lower. The line passing performance of the tooling line is better, and the supporting investment cost can also be lower.

[0072] Reference will now be made to Figures 1-8 A non-integrated upper body tooling line 100 according to an embodiment of the present application is described.

[0073] As shown in Figure 1 and Figure 2 The present application provides a non-integrated upper body tooling line 100.

[0074] As shown in Figures 3-8 The tooling line includes a guide rail, a door tooling 20, a cover tooling 30, a side wall tooling 40, a fender tooling 50, and a driving member 60.

[0075] The door tooling is used to hoist the door and is movably arranged on the guide rail, the cover tooling is used to hoist the cover and is movably arranged on the guide rail, the side wall tooling is used to hoist the side wall and is movably arranged on the guide rail, the fender tooling 50 is used to hoist the fender and is movably arranged on the guide rail, and the driving member 60 is power connected with the door tooling, the cover tooling, the side wall tooling, and the fender tooling 50 to drive the door tooling, the cover tooling, the side wall tooling, and the fender tooling 50 to move on the guide rail.

[0076] Specifically, the non-integrated upper body is divided into a door, a cover, a side wall, and a fender, the door can be hoisted by the door tooling 20, the cover can be hoisted by the cover tooling 30, the side wall can be hoisted by the side wall tooling 40, and the fender can be hoisted by the fender tooling 50, and the driving member 60 can be configured as any one of a transmission chain type transmission structure, a gear and rack type transmission structure, a conveyor belt type transmission structure, etc. to drive the door, the cover, the side wall, and the fender to circulate between multiple process steps and be transported to the final assembly workshop after completing all process steps.

[0077] It can be understood that the non-integrated upper body is divided into four doors, two covers, and fenders, side walls, etc. and is circulated by the tooling line of the present application at the same time. During the circulation process, compared with the circulation process of the white body, the space occupation of each component is smaller, the size and space requirement when setting the process equipment, workshop matched with the tooling line of the present application is lower, the investment cost can be reduced and the production line passability can be improved.

[0078] It should be noted that based on the sub-assembly assembly relationship of the non-integrated upper body and the integrated intelligent chassis, some process steps of the existing white body do not need to be performed for the non-integrated upper body, so that during the process circulation process of the non-integrated upper body of the present application, the process steps that do not need to be performed can be omitted, the energy consumption during the process circulation process can be reduced, and during the process circulation process, the pry operation is not required, the process steps and process flow can be simplified, and the process space requirement can be reduced to reduce the equipment investment.

[0079] According to the assembly line 100 provided by the application, on the one hand, the door, the cover plate, the side wall and the fender can be hoisted and then transferred, and the process of transferring the non-central body can be realized. On the other hand, during the process of transferring, the space occupied by each component of the non-central body is smaller, and the change of the pry operation is not required, the process space requirement is lower, the investment cost of the supporting equipment and the workshop can be reduced, and the production line passability can be improved.

[0080] It can be understood that the process steps described above can be process steps for the painting workshop.

[0081] In combination with the figures shown in Figure 1 , Figure 3 and Figure 4 , according to some embodiments of the application, the door tooling 20 includes: a front door tooling 20a and a rear door tooling 20b, the front door tooling 20a is used for hoisting the front door, and the rear door tooling 20b is used for hoisting the rear door.

[0082] That is, the door of the embodiments of the application can include a front door and a rear door, and the front door includes a left front door and a right front door, and the rear door includes a left rear door and a right rear door. The front door tooling 20a can be used for hoisting the left front door and the right front door, and at least one front door tooling 20a can be arranged on the guide rail 10. The rear door tooling 20b can be used for hoisting the left rear door and the right rear door, and at least one rear door tooling 20b can be arranged on the guide rail 10.

[0083] Therefore, the front door and the rear door can be hoisted by the corresponding front door tooling 20a and the rear door tooling 20b respectively, the installation difficulty of the front door and the rear door is lower, the adaptability is better, the fixing stability of the front door and the rear door during the transfer process is higher, and the processing quality of the front door and the rear door during the process of transferring in multiple process steps can also be improved.

[0084] As shown in Figure 3 and Figure 4 , according to some embodiments of the application, the front door tooling 20a and the rear door tooling 20b each include: a first guide wheel part 21, a first connecting rod 22 and a first fixing part 23. The first guide wheel part 21 is movably arranged on the guide rail 10. One end of the first connecting rod 22 is connected with the first guide wheel part 21, and the other end of the first connecting rod 22 is connected with the first fixing part 23. The first fixing part 23 is used for fixing the front door or the rear door.

[0085] Specifically, the first connecting rod 22 can extend along the first direction and is connected with the first fixed part 23 and the first guide wheel part 21 at two ends respectively, so that the distance between the first fixed part 23 and the first guide wheel part 21 is more reasonable, the distance between the top edge of the door and the guide rail 10 is more reasonable, the distance between the bottom edge of the door and the lower obstacle is more reasonable, and the movement stability and reliability of the door on the assembly line 100 are improved.

[0086] It should be noted that the first direction of the embodiment of the present application is the height direction, the second direction is the left-right direction, the third direction is the front-rear direction, and the third direction is also the direction of movement of the plurality of fixtures on the assembly line 100.

[0087] According to some embodiments of the present application, the first fixed part 23 is used to be connected with the door hinge of the front door or the rear door.

[0088] That is, the first fixed part 23 is directly connected with the door hinge of the front door or the door hinge of the rear door, so that the first fixed part 23 can be fixed by using the existing door hinge on the door, without further opening a fixed point or a support point on the door, without improving the existing door, and the assembly difficulty between the first fixed part 23 and the door can be reduced and the assembly efficiency can be improved.

[0089] It can be understood that the number of hinges on the door can be multiple, and the number of the first fixed part 23 can also be multiple, which can further improve the fixing stability and reliability of the door on the door fixture 20.
