The common transport device is mainly composed of a vehicle body, a placement plate, a control system, a limit plate, a power supply device and other mechanisms. The specific process of the transport device for transporting new energy vehicle parts is as follows: the new energy vehicle parts are placed on the upper surface of the limit plate. With the support of the control system and the power supply device, the limit plate performs a limit operation on the parts.

[0040] The specific working process of the embodiments of this part of the application is as follows: the new energy vehicle battery is placed on the surface of the weight sensing device 3, and the pressure sensor collects the pressure data at the four corners of the surface of the weight sensing device 3 and transmits it to the control module. The control module judges in real time whether the placement position of the new energy vehicle battery is in the middle position of the weight sensing device 3 through the change of the pressure data, so as to avoid the transportation robot 2 and the mobile mechanism 4 during the transportation process.

An air groove 509 is opened inside the limit main board 5 for storing compressed air. The compressed air in the air groove 509 is input into the second rubber layer 508 through the electric control valve 510, driving the second rubber layer 508 to be in an expanded state.

[0045] A Y-shaped delivery pipe 701 is installed at the output end of the air pump 7, and the end of the Y-shaped delivery pipe 701 away from the position of the air pump 7 is installed inside the air groove 509, and a first delivery pipe 702 is installed through the top of the limiting main board 5 near the first telescopic plate 504, and the end of the first delivery pipe 702 away from the position of the limiting main board 5 is installed in the cavity of the first telescopic plate 504, wherein an electromagnetic valve is installed inside the first delivery pipe 702.

[0051] The bottoms of both sides of the fire-fighting device 601 are movably sleeved in the slide rail 505 , so that the fire-fighting device 601 can move parallel to the surface of the slide rail 505 .

[0052] The specific working process of the embodiment of the present application is as follows: the control module determines whether an open flame occurs in the new energy battery through real-time temperature data. When an open flame occurs in the new energy battery, the control module drives the fire-fighting device 601 to input a stable working current, and sprays the fire-fighting agent inside the fire-fighting device 601 through the nozzle 602 to the surface of the corresponding new energy battery, thereby achieving the effect of automatic fire extinguishing.

A transportation device for new energy vehicle production according to claim 1, characterized in that: An auxiliary delivery pipe (603) is installed through the inner wall of the stretch support plate (6), and one end of the auxiliary delivery pipe (603) away from the stretch support plate (6) is installed inside the air groove (509), and a fire-fighting device (601) is installed on the side of the stretch support plate (6) close to the weight sensing device (3), and a nozzle (602) is installed vertically through the inner wall of the bottom of the fire-fighting device (601). A temperature sensor is installed on the ground of the fire-fighting device (601) near the nozzle (602) for collecting real-time temperature data of the new energy vehicle battery and transmitting it to the control module.

4. A transportation device for new energy vehicle production according to claim 3, characterized in that: The control module comprises a threshold unit, wherein the threshold unit pre-stores a first threshold range, and the threshold unit is used to receive four sets of real-time pressure data transmitted by the pressure sensor, and respectively compare the four sets of real-time pressure data with the first threshold range. When one set of real-time pressure data is greater than the first threshold range, it can be determined that the placement position of the new energy vehicle is biased towards that position, and the control module drives the air pump (7) to input a stable working current, and controls the corresponding first rubber layer (507) and second rubber layer (508) to input compressed air, thereby driving the placement position of the new energy vehicle battery to be adjusted.

5. A transportation device for new energy vehicle production according to claim 4, characterized in that: The control module also includes an alarm device and a temperature sensing unit. The temperature sensing unit is used to receive and analyze the real-time temperature transmitted by the temperature sensor. When the temperature sensing unit determines that the real-time temperature is in an open flame state, the control module drives the air pump (7) and the fire-fighting device (601) to input a stable working current, thereby driving the stretching support plate (6) in a stretched state. At the same time, the fire-fighting device (601) sprays the internal fire-fighting agent onto the surface of the new energy vehicle battery in sequence, thereby achieving an automatic fire-extinguishing effect. At the same time, the warning device emits a warning sound to remind staff to arrive at the scene for inspection.
