[0030] See also Figure 1 and Figure 2 As shown, the utility model is a cross-building transfer vehicle, comprising an automatic guided vehicle 1, a central control box 2 and a bearing platform.

[0031] The automatic guided vehicle 1 has the ability to travel automatically and can travel according to a set path. In one example, the automatic guided vehicle 1 is generally in the shape of a rectangular parallelepiped, and the top of the automatic guided vehicle 1 has a horizontal installation plane.

[0032] The central control box 2 is generally in the shape of a rectangular parallelepiped, and is fixedly mounted on the mounting plane. The central control box 2 is located at one end of the mounting plane along the length direction of the automatic guided vehicle 1, so that the front of the central control box 2 is flush with the front of the automatic guided vehicle 1, and the width of the central control box 2 is equal to the width of the automatic guided vehicle 1, so that the two sides of the central control box 2 are respectively flush with the two sides of the automatic guided vehicle 1. A control unit is provided in the central control box 2, and the control unit can control the start and stop of the automatic guided vehicle 1, so that the automatic guided vehicle 1 drives according to the set program.

[0033] The carrier is used to carry the wafer box 100. In the present application, the carrier includes a first carrier 3 disposed on the installation plane and a second carrier 4 disposed above the first carrier 3. The first carrier 3 and the second carrier 4 are located on the same side of the central control box 2, and the second carrier 4 is fixedly mounted on the back of the central control box 2. Along the driving direction of the automatic guided vehicle 1, the central control box 2 is located at the front end of the first carrier 3 and the second carrier 4. The central control box 2 can stop the wafer boxes 100 on the first carrier 3 and the second carrier 4 at the same time to prevent the wafer boxes 100 on the first carrier 3 and the second carrier 4 from falling due to sudden braking during driving, which greatly ensures the safety of the wafer boxes 100 during driving.

[0034] In one example, a control panel 5 is installed on the front of the central control box 2. The control panel 5 is a touch control panel 5, so that an operator can directly operate on the touch control panel 5 to let the automatic guided vehicle 1 perform corresponding tasks.

[0035] A cooling fan 6 is also installed on the front of the central control box 2. The cooling fan 6 is used to dissipate heat from the control unit in the central control box 2 to increase the service life of the control center.

[0036] A warning light 7 is installed on the top of the central control box 2. The warning light 7 can promptly remind the operator and surrounding personnel when an abnormal situation occurs in the inter-building transfer vehicle, and when the inter-building transfer vehicle needs to be shut down for maintenance or special operations, so as to reduce equipment damage, extend the service life of the inter-building transfer vehicle, and reduce the company's operating costs.

[0037] An emergency stop button 8 is provided on the side of the central control box 2. When an abnormal situation occurs in the inter-building transfer trolley, the operator can press the emergency stop button 8 to quickly stop the inter-building transfer trolley.

[0038] In one example, the inter-building transfer vehicle also includes a horizontal radar 9 arranged on the automatic guided vehicle 1 and a vertical radar 10 arranged on the central control box 2. There are two horizontal radars 9, which are relatively installed at the front and rear ends of the automatic guided vehicle 1 along its length direction. The horizontal radars 9 can detect obstacles in the horizontal plane of 360 degrees around the front and rear of the inter-building transfer vehicle. When the obstacles enter the set range, the inter-building transfer vehicle can reduce the speed or stop. There are two vertical radars 10, which are relatively installed on both sides of the central control box 2 along the width direction of the automatic guided vehicle 1. The vertical radars 10 can detect obstacles in the vertical plane of 360 degrees around the front and rear of the inter-building transfer vehicle. When the obstacles enter the set range, the inter-building transfer vehicle can reduce the speed or stop.

[0039] In one example, 6 anti-fall sensors 11 are arranged around the bottom of the automatic guided vehicle 1, wherein two anti-fall sensors 11 are respectively installed at the front and rear ends of the automatic guided vehicle 1, and the other two anti-fall sensors 11 are respectively installed on both sides of the automatic guided vehicle 1 and near its front end. The anti-fall sensor 11 can detect whether there is a hole (hollow in the elevated floor) around the cross-building transfer vehicle to prevent the cross-building transfer vehicle from falling. Two ultrasonic radars 12 are also respectively arranged at the front and rear ends of the automatic guided vehicle 1. The ultrasonic radar 12 can detect obstacles including glass materials around the cross-building transfer vehicle. When the obstacles enter the set range, the cross-building transfer vehicle can reduce the speed of travel. An E84 sensor 13 is installed on one side of the automatic guided vehicle 1. The E84 sensor 13 is used for the cross-building transfer vehicle to perform the pick-up and placement of the wafer box 100 on the loading and unloading platform of the customer's production machine. It can exchange information with the machine on the process status of the wafer box 100 on the loading and unloading platform to ensure that the wafer box 100 can be taken down or put up to prevent misoperation.

[0040] In one example, turn signals 14 are installed around the AGV 1 near its top, and the turn signals 14 are used to flash before the AGV 1 turns to remind the staff to avoid in advance.

[0041] In one example, the bottom of the automatic guided vehicle 1 has two sets of guide wheels 15, each set of guide wheels 15 includes two differential wheels arranged in parallel, and the automatic guided vehicle 1 can flexibly turn through the differential wheels.

[0042] In one example, the automatic guided vehicle 1 further includes a battery (not shown) for providing kinetic energy to the guide wheel 15, so that the automatic guided vehicle 1 is electrically driven. Preferably, the battery has a charging port 16, and the charging port 16 is installed on the rear end surface of the automatic guided vehicle 1, so that an external power source can replenish the battery with electric energy through the charging port 16, avoiding the need to remove the battery from the automatic guided vehicle 1 when charging the battery.

[0043] In one example, a circle of anti-collision bumpers 17 are arranged around the bottom of the automatic guided vehicle 1 to provide a final physical protection when there are obstacles on the ground to prevent the automatic guided vehicle 1 from directly contacting the obstacles.

[0044] In one example, the inter-building transfer vehicle also includes installed monitoring, which includes four cameras 18 respectively arranged on the front, two sides and the top of the central control box 2. The four cameras 18 respectively record the working environment, personnel movements, and cargo picking and delivery procedures around the central control box 2 through video for playback and viewing.

[0045] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
