[0002] In the technical field of automobile general assembly, especially in the general assembly process of new energy pure electric vehicles, the traditional assembly platform has been difficult to meet the current production requirements. With the wide application of digital and intelligent integration technologies in the construction of new energy production capacity, the upgrading and transformation of production capacity can be realized.

[0003] However, under the background of the existing technology, the automobile manufacturing faces some significant problems. The original production models were developed according to the traditional line process, using the assembly line mode with a low automation rate and relying mostly on manual assembly. This production mode has relatively low requirements for product design and accuracy, resulting in the design of the original mass-produced models not meeting the requirements of the new production line operation. Especially in terms of the form of mechanical transportation and the overall chassis assembly, there are many mismatching problems. For example, there are no positioning holes, and the assembly of related parts does not meet the requirements of connecting and assembling after the overall chassis assembly, resulting in low assembly efficiency and difficult-to-guarantee accuracy.

[0019] The following further describes the embodiments of the utility model in detail with reference to the accompanying drawings of the specification, so as to more clearly present the purpose, technical solution, and technical effect of the present utility model.

[0020] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model. In addition, the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance.

[0021] Such as Figure 1As shown, it is an island-type assembly platform for automobiles, which includes a basic parts area, an unmanned assembly area, a chassis area and a maintenance area in sequence. The basic parts area corresponds to the optional area, door subassembly and cockpit subassembly; the chassis area corresponds to the front and rear bumper subassembly and the three-electric drive subassembly; the maintenance area corresponds to the customization area. The assembly platform uses AGV to support and transport the vehicle body, and the mechanical hoist and the AGV body in the assembly use positioning pins and supports with the same specifications and position requirements. The positioning pins correspond to the positioning holes at the bottom of the vehicle body, and the supports correspond to the support surfaces at the bottom of the vehicle body. Four positioning pins and supports are set respectively, and correspond to the front frame and the rear frame. The positioning holes on the X-axis of the vehicle body are long strip positioning holes.

[0022] The chassis area is equipped with chassis hoists for lifting the vehicle body. The chassis hoists have the functions of Z-axis lifting and X / Y-axis adjustment, which can meet the mixed-line production of models with different vehicle widths and wheelbases; the front subframe, battery, and front, middle, and rear pallets of the rear axle, the front subframes of each model have unified fixed positioning pins, and the batteries share pins on the same platform, and different platforms try to share them. If they are not satisfied, the pins are used, and the pallets are adjusted in series according to different wheelbase models.

[0023] The AGV is provided with a positioning support frame, which is fixedly connected to the AGV, and the support frame is provided with the positioning pin and the support. The positioning pin is hingedly connected to the support frame, and the support frame is provided with a groove corresponding to the positioning pin. The Z-direction height difference of the positioning pin positioning hole is 0. A rubber gasket is provided on the upper end surface of the support.

[0024] Based on the principle of regional division of labor, the automobile assembly process is divided into different areas, each area is responsible for specific subassembly tasks, which improves the degree of specialization and efficiency. The automatic transportation function of AGV is used to achieve efficient movement of the car body, and accurate positioning is achieved through the coordination of the positioning pins and supports with the positioning holes and support surfaces at the bottom of the car body. The long strip positioning holes on the X-axis of the car body adapt to the deformation and assembly requirements of the car body in certain directions, and the chassis hoist realizes the lifting of the car body through a mechanical structure. The foldable storage structure of the positioning pin is realized through the groove design of the hinge and the support frame, which is convenient to use and saves space. The rubber gasket on the upper end surface of the support uses the elasticity and friction principle of rubber to enhance the support effect.

[0025] The operation process includes: First, in the basic parts area, the AGV transports the car body to the corresponding position, and uses the positioning pins and supports to coordinate with the positioning holes and support surfaces at the bottom of the car body to position it, and then carry out the optional area, door subassembly and cockpit subassembly. Then, the AGV transports the car body to the chassis area, and the chassis hoist lifts the car body to carry out front and rear protection subassembly and three-electric drive subassembly. In this process, the positioning pins and supports also play a role in precise positioning. Then, the car body is transported to the preparation area for related work in the customization area. During the whole process, when the positioning pins are not needed, they can be folded and stored in the groove of the support frame through the hinged structure.

[0026] The above are only the preferred and feasible embodiments of the present utility model, and are not intended to limit the scope of the patent application of the present utility model. Any equivalent changes, equivalent substitutions or modified changes completed within the technical spirit and principles disclosed by the present utility model shall be included within the scope of patent protection covered by the present utility model.
