[0016] like Figure 1 and Figure 2 A body-in-white transfer and hanging adjustment line device is shown, comprising a plate chain device 1, each station of the plate chain device 1 is provided with a front support leg 2 and a rear support leg 3 for supporting the front and rear sides of the body-in-white 10, and each station of the plate chain device 1 is provided with a first photoelectric sensor 4 and a second photoelectric sensor 5 at the positions corresponding to the front support leg 2 and the rear support leg 3, and each station of the plate chain device 1 is provided with a third photoelectric sensor 6 for detecting whether the body-in-white 10 is parked in place, and the first photoelectric sensor 4 and the second photoelectric sensor 5 are electrically connected to the first PLC controller of the plate chain device 1, and the third photoelectric sensor 6 is electrically connected to the second PLC controller of the EMS aerial suspension trolley. The above-mentioned photoelectric sensor can use the through-beam photoelectric switch / sensor provided by Pepperl+Fuchs of Germany.

[0017] Preferably, in combination with the above scheme, in order to facilitate the installation of the first photoelectric sensor 4, the second photoelectric sensor 5, and the third photoelectric sensor 6, the first photoelectric sensor 4, the second photoelectric sensor 5, and the third photoelectric sensor 6 are all fixedly arranged on the ground on the left and right sides of the plate chain device 1 through brackets.

[0018] Preferably, in combination with the above solution, in order to facilitate the installation of the transmitting end and the receiving end of the first photoelectric sensor 4, a pair of the first photoelectric sensors 4 are provided, and are relatively arranged on the left and right sides of each station of the plate chain device 1.

[0019] Preferably, in combination with the above solution, in order to facilitate the installation of the transmitting end and the receiving end of the second photoelectric sensor 5, a pair of the second photoelectric sensors 5 are provided, and are relatively arranged on the left and right sides of each station of the plate chain device 1.

[0020] Preferably, in combination with the above scheme, in order to facilitate the installation of the transmitting end and the receiving end of the third photoelectric sensor 6, a pair of the third photoelectric sensor 6 is provided, and are relatively arranged on the left and right sides of each workstation of the plate chain device 1, and the height of the third photoelectric sensor 6 corresponds to the bottom edge position of the body in white 10 after it is parked in place.

[0021] Preferably, in combination with the above scheme, in order to prevent personnel from crossing the plate chain device 1 and causing safety hazards, a pair of safety gratings 7 are also provided on the side of each workstation of the plate chain device 1, and the safety grating 7 is arranged in front of the white body 10 after it stops in place at each workstation. Since there is a certain interval between the two vehicles at every two workstations, when the plate chain drives the body to move, there is a fixed interval movement time. When a person crosses the plate chain, the safety grating 7 detects that it is blocked by foreign objects before the interval movement time, and automatically disconnects the plate chain power supply to ensure the safety of the personnel. The safety grating 7 also includes a transmitting end and a receiving end, and can adopt the LCS1435G1NT / PZ model provided by Shandong Keli Optoelectronic Technology Co., Ltd.

[0023] The working principle and steps of this utility model:

[0024] When the plate chain device 1 moves, after the first photoelectric sensor 4 and the second photoelectric sensor 5 simultaneously detect that the front leg 2 and the rear leg 3 are blocked, the plate chain stops moving, and the plate chain is in place signal is fed back to the PLC second controller of the EMS aerial suspension trolley through the PLC first controller; after receiving the plate chain in place signal, the EMS trolley lowers the body-in-white and parks the body-in-white on the front leg 2 and the rear leg 3 of the plate chain; when the body-in-white is parked in place, the third photoelectric sensor 6 detects that the bottom edge of the body-in-white is in place, and feeds back a signal to the PLC second controller of the EMS trolley, and the EMS trolley automatically opens the clamp, rises to a safe height and then automatically moves forward.

[0025] After the plate chain system of the old workshop is simply modified through the above-mentioned hardware, it can automatically realize the function of transferring the white body, without the need for major reconstruction of the workshop, thus reducing the construction period and ensuring production efficiency.

[0026] It should be noted that all directional indications in the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components in a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.
