[0037] In this embodiment, the concept of the vehicle head is rationally used, and the trolley 1 is used as a power to drive the tray 11 along the guide rail 2; in actual use, it can be compatible with the transportation of various types of trays 6.

[0038] It also includes a charging point 3, and the trolley 1 moves along the guide rail 2 to the charging point 3 for charging.

[0039] In this embodiment, a battery is installed on the trolley 1 , and the electric energy of the battery provides energy for the operation of the trolley 1 ; the battery can be charged at a charging point 3 .

[0040] In actual use, a 200AH ternary lithium battery is selected, and a 3KW inverter is used to give the car 1 strong power through the ternary lithium battery inverter principle.

[0041] The guide rail 2 further includes a to-be-tested area 41 . The test point 4 and the to-be-tested area 41 are arranged on both sides of the guide rail 2 .

[0042] In actual use, the tray 6 can be temporarily placed in the to-be-tested area 41 , which is close to the test point 4 , and the tray 6 in the to-be-tested area 41 waits for testing at the test point 4 .

[0043] like Figure 2 As shown, the connecting member 10 is a rod, and both ends of the rod are rotatably mounted on the end surfaces of the trolley 1 and the tray 11 respectively, and the axial direction of rotation is arranged along the width direction of the guide rail 2.

[0044] In this embodiment, the rod effectively connects the tray 11 to the trolley 1, so that the tray 11 and the trolley 1 can move synchronously along the guide rail 2; and the two ends of the rod can be rotated to install, so that the tray 11 and the trolley 1 can maintain smooth and stable driving, which is particularly suitable for smooth switching between tracked and trackless vehicles.

[0045] The four corners of the trolley 1 and the tray 11 are respectively provided with running wheels 15 , and the trolley 1 and the tray 11 are equipped to run on the guide rail 2 ; a photoelectric switch is installed on the trolley 1 , and a photoelectric emitting board is buried on the guide rail 2 .

[0046] In this embodiment, during the movement of the trolley 1, the photoelectric switch can detect the photoelectric emitting board to perform coordinate calibration, which effectively reduces or even avoids abnormal operation of the equipment caused by cumulative errors.

[0047] The guide rail 2 is arranged discontinuously in the length direction to facilitate the free movement of other devices in the workshop, including forklifts, etc. The travel wheel 15 includes a large wheel portion 151 and a small wheel portion 152 coaxially arranged along the axial direction, and the small wheel portion 152 is located on the outside; when the travel wheel 15 travels on the guide rail 2, the large wheel portion 151 is located on the inside of the guide rail 2, and the step formed between the large wheel portion 151 and the small wheel portion 152 constitutes a limit relative to the width direction of the guide rail 2, and the small wheel portion 152 travels on the guide rail 2; the circumferential wall surface of the small wheel portion 152 is covered with a rubber coating, and the rubber coating is made of polyurethane.
