The car base is divided into an assembly surface for installing components and a non-assembly surface opposite to the assembly surface.

[0039] See also Figure 1 and Figure 2 The first assembly unit 6 includes a first frame 61, a first assembly platform 62 arranged on the first frame 61, an annular guide rail 63 arranged on the first assembly platform 62, a plurality of first assembly fixtures 65 that can move cyclically along the annular guide rail 63, a positioning device 66 arranged on the annular guide rail 63 and a first assembly control system; the first assembly fixture 65 is used to lock the vehicle base; the first assembly control system controls the first assembly fixture 65 and the positioning device 66.

[0040] See also Figure 1 and Figure 3 The vehicle base selection unit 1 includes a vehicle base screening device 11 for changing the placement state of the vehicle base, a vehicle base feeding device 12 for quantitatively conveying the vehicle base to the vehicle base screening device 11, a vehicle base identification device 13, a vehicle base grasping device 14 for grasping the vehicle base that meets the installation state, and a vehicle base control system; the vehicle base identification device 13 is arranged above the vehicle base screening device 11; the vehicle base control system controls the vehicle base screening device 11, the vehicle base feeding device 12, the vehicle base identification device 13, and the vehicle base grasping device 14. The vehicle base that meets the installation state is a vehicle base with the assembly surface or the non-assembly surface facing upward.

[0041] In this embodiment, the vehicle base screening device 11 includes a vehicle base vibration plate 111 for accommodating the vehicle base and a vehicle base vibrator 112 connected to the vehicle base vibration plate 111. The vehicle base feeding device 12 includes a vehicle base conveying device 122 leading to the vehicle base screening device 11 and a vehicle base hopper 124 for placing the vehicle base on the vehicle base conveying device 122. The vehicle base conveying device 122 guides the vehicle base vibration plate 111, and the vehicle base hopper 124 is arranged above the vehicle base conveying device 122, and the discharge port of the vehicle base hopper 124 faces the vehicle base conveying device 122; the vehicle base conveying device 122 is preferably a conveyor belt. The vibration of the vehicle base vibrator 112 causes the vehicle base material in the vehicle base vibration plate 111 to flip, move and evenly distribute in the vehicle base vibration plate 111, thereby changing the placement state of the vehicle base in the vehicle base vibration plate 111. The vibration frequency and amplitude of the vehicle base vibrator 112 can be set by the vehicle base control system to avoid high-frequency repeated shaking to scratch the surface of the vehicle base, and the vehicle base control system can control the instant vibration of the vehicle base vibrator 112. The vehicle base identification device 13 includes a vehicle base visual input lens 131; the vehicle base visual input lens 131 is arranged above the vehicle base vibration plate 111 and faces the vehicle base vibration plate 111, and the vehicle base visual input lens 131 shoots the vehicle base in the vehicle base vibration plate 111 and inputs the shooting information into the vehicle base control system. The vehicle base control system controls the vehicle base hopper 124 to place the vehicle base on the vehicle base conveying device 122, and controls the vehicle base conveying device 122 to convey the vehicle base to the vehicle base vibration disk 111. When the vehicle base in the vehicle base vibration disk 111 reaches a certain capacity, the vehicle base control system controls the vehicle base conveying device 122 and the vehicle base hopper 124 to stop operating; when the vehicle base vibration disk 111 stops vibrating, the vehicle base control system identifies the vehicle base and its placement status in the picture taken by the vehicle base visual input lens 131, marks it when identifying the vehicle base with the assembly surface facing up, and controls the vehicle base grasping device 14 to grasp the marked vehicle base in the vehicle base vibration disk 111 and move and place it on the first assembly fixture 65 locked in the vehicle base assembly position; when the vehicle base with the assembly surface facing up cannot be identified, the vehicle base control system controls the vehicle base vibrator 112 to vibrate for a certain period of time and then stop, so that the vehicle base raw material in the vehicle base vibration disk 111 is turned over until the vehicle base with the assembly surface facing up is identified. Furthermore, the vehicle base control system also has the function of identifying unqualified vehicle bases, such as damaged, missing, etc.; when the vehicle base control system identifies an unqualified vehicle base, it alerts the operator by issuing an alarm, or controls the vehicle base grabbing device 14 to grab the unqualified vehicle base and place it in other storage devices.

[0042] Since the vehicle base is divided into an assembly surface and a non-assembly surface for mounting components, in order to reduce the vibration frequency of the vehicle base vibrator 112, improve the efficiency of the vehicle base grasping components, and further avoid high-frequency repeated shaking to scratch the surface of the vehicle base, as a further improvement of the above scheme, the vehicle base control system can also mark the vehicle base with the non-assembly surface facing upward. The vehicle base selection unit 1 also includes a vehicle base reversal device 16, which is provided with at least one vehicle base reversal fixture; the vehicle base reversal device 16 is controlled by the vehicle base control system. The vehicle base control system identifies the vehicle base and its placement status in the picture taken by the vehicle base visual input lens 131, and marks the vehicle base with the non-assembly surface facing upward for inversion, and at the same time controls the vehicle base grasping device 14 to grasp the vehicle base marked for inversion in the vehicle base vibration plate 111 and put it into the vehicle base inversion fixture of the vehicle base inversion device 16, and the vehicle base inversion device 16 is reversed to make the vehicle base in the vehicle base inversion fixture flip 180 degrees, so that its assembly surface faces upward, and then the vehicle base grasping device 14 grabs the inverted vehicle base and moves and places it on the first assembly fixture 65 locked in the vehicle base assembly position. When the vehicle base with the assembly surface facing upward and the non-assembly surface facing upward cannot be identified, the vehicle base control system controls the vehicle base vibrator 112 to vibrate for a certain period of time and then stops to flip the vehicle base material in the vehicle base vibration plate 111 until the vehicle base with the assembly surface facing upward or the non-assembly surface facing upward is identified.

[0043] As a further improvement of the above solution, the vehicle base recognition device 13 further includes a vehicle base light source 132 for facilitating the vehicle base visual input lens 131 to shoot.

Specifically, the special obstacle and the wheel axle spiral conveyor form a transmission channel and a non-transmission channel that conform to the shape of the wheel axle. In addition, the special obstacle can flip the direction of the wheel axle and change the position and direction of travel of the wheel axle by colliding with the wheel axle, so that the wheel axle enters the transmission channel with the correct orientation and position; and the wheel axle with incorrect orientation re-enters the wheel axle trough from the non-transmission channel and repeats the above wheel axle transportation process.
