DETAILED DESCRIPTION

[0022] In order to enable those skilled in the art to better understand the technical solution of the present invention, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention.

[0023] Example 1

[0024] like Figure 1 As shown, this embodiment provides an automatic glass substrate transfer vehicle, including an AGV vehicle 1, which can send instructions through a local area network to achieve position navigation and has a function of stopping when encountering obstacles, thereby achieving automatic transfer of glass substrates on a fixed route. The AGV vehicle 1 is equipped with a support frame, such as Figure 1-2 As shown, the support frame includes a support base 1401, which is fixed to the AGV trolley 1 by bolts, and two vertical poles 1402 are symmetrically arranged on the support base 1401, and a mounting seat 6 is arranged on the top of the vertical pole 1402, and a plug rod 15 is inserted into the mounting seat 6, and a rotating shaft 7 is fixedly connected to the plug rod 15, and the rotating shaft 7 is fixedly connected to the mounting seat 2 8, and the mounting seat 2 8 is fixed to the glass substrate storage rack 2, and the glass is placed on the glass substrate storage rack 2. The glass substrate storage rack 2 is hinged to the mounting seat 6 by the rotating shaft 7 and the plug rod 15, so that the glass substrate storage rack 2 can be rotated with the mounting seat 6 as the base point.

[0025] At the same time, if Figure 1 , 3As shown, a second vertical pole 1403 whose height is lower than that of the first vertical pole 1402 is provided on the support base 1401 between the two first vertical poles 1402, and a motor 3 is installed on the top of the second vertical pole 1403. The output shaft of the motor 3 is connected to a rocker 4, and the other end of the rocker 4 is connected to a connecting rod 5 through a second plug rod 16. The rocker 4 and the connecting rod 5 can rotate around the second plug rod 16, so that the rocker 4 is hinged on the connecting rod 5; the other end of the connecting rod 5 is connected to a mounting seat 3 9 through a third plug rod 17. The connecting rod 5 and the mounting seat 3 9 can rotate around the third plug rod 17, so that the connecting rod 5 is hinged on the mounting seat 3 9, and the mounting seat 3 9 is fixed on the glass substrate storage rack 2. Start the motor 3, and the output shaft of the motor 3 drives the rocker 4 to rotate, so that the connecting rod 5 moves accordingly, and finally the glass substrate storage rack 2 can switch between a horizontal state and an inclined state. In addition, in order to ensure the smooth state switching, as Figure 1-2 As shown in , 5-6, photoelectric switches 10 can be respectively arranged on the supporting base 1401 and on the top of one of the vertical poles 1402. When the state of the glass substrate storage rack 2 is switched, the two photoelectric switches 10 cannot detect the glass substrate storage rack 2. When the glass substrate storage rack 2 is adjusted to a horizontal state, the photoelectric switch 10 on the top of the vertical pole 1402 can detect the glass substrate storage rack 2 and feed back a signal to the controller, indicating that the horizontal state switching is successful, and the motor 3 is turned off at this time; and when the glass substrate storage rack 2 is adjusted to an inclined state, the photoelectric switch 10 on the supporting base 1401 can detect the glass substrate storage rack 2 and feed back a signal to the controller, indicating that the inclined state switching is successful, and the motor 3 is turned off at this time; if the two photoelectric switches 10 cannot detect the glass substrate storage rack 2 for a long time during the switching process, the controller will alarm to remind the staff that the device has a fault.

[0026] The glass substrate storage rack 2 is used to place glass substrates. Figure 1 As shown, in this embodiment, the specific structure is a rectangular frame formed by a plurality of horizontal bars 201 and vertical bars 202 fixedly connected, and the glass substrate rests on the frame. In addition, in order to ensure that the glass substrate will not fall when it is placed on the glass substrate storage rack 2 at an angle, as shown in FIG. Figure 1 , 4 As shown in FIG. 6 , a plurality of limiting support plates 13 may be provided at the bottom of the glass substrate storage rack 2. After the glass substrate is leaned against the glass substrate storage rack 2, the bottom is placed on the limiting support plates 13, thereby ensuring that the glass substrate is stably placed during the transportation process.

[0027] Take the case where a glass substrate is stored in a tilted state on a trolley for transportation as an example. When in use, the glass substrate is moved to the glass substrate storage rack 2 and tilted against the glass substrate storage rack 2. The bottom of the glass substrate is placed on the limit support plate 13. Then the controller controls the AGV trolley 1 to transport the glass substrate to the destination along a fixed route. When the glass substrate needs to be transported in a horizontal state, it is only necessary to start the motor 3. The motor 3 flips the glass substrate storage rack 2 to a horizontal state through the rocker 4 and the connecting rod 5. At this time, the photoelectric switch 10 on the top of the vertical pole 1402 detects the glass substrate storage rack 2, and the controller turns off the motor 3 to switch the glass substrate storage rack 2 to a horizontal state.

[0028] Example 2

[0029] On the basis of Example 1, Figure 1 , 4 As shown, a 3 mm buffer pad 11 is pasted on the side of the glass substrate storage rack 2 that contacts the glass substrate. The buffer pad 11 can be a silicone rubber pad to increase the friction between the glass substrate and the glass substrate storage rack 2, thereby preventing the glass substrate from being damaged during transportation.

[0030] In addition, since the bottom of the glass substrate storage rack 2 will abut against the supporting base 1401 when the glass substrate storage rack 2 is in an inclined state, Figure 4 , 6 As shown, a buffer pad 12 can be set at the position where the glass substrate storage rack 2 contacts the support base 1401. The buffer pad 12 can be made of silicone rubber pads, which can play a buffering role when the glass substrate storage rack 2 is flipped to an inclined state to prevent the glass substrate storage rack 2 and the support base 1401 from being damaged due to collision.
