Description

Technical Field

[0001] The present invention relates to the technical field of AGV vehicles, and particularly to an AGV vehicle for material transportation. Background Art

[0002] An AGV vehicle generally refers to a transport vehicle equipped with an automatic guiding device such as electromagnetic or optical, capable of traveling along a specified guiding path, having safety protection and various transfer functions, a forklift truck without a driver in industrial applications, powered by a rechargeable battery, and generally controlled by a computer for its traveling route and behavior, or using an electromagnetic rail to set up its traveling route. The electromagnetic rail is adhered to the floor, and the driverless transport vehicle moves and operates relying on the information brought by the electromagnetic rail.

[0003] Patent No. CN115743361B discloses a material conveying AGV automatic guiding vehicle, including a vehicle body arranged in a concave shape and a placement table arranged on the top of the vehicle body. The placement table is arranged in the middle of the vehicle body, and the placement table is telescopically arranged on the top of the vehicle body. A clamping seat is also arranged on the vehicle body, and the clamping seat is arranged on both sides of the placement table. The clamping seat can be telescopically arranged in the front, back, left, and right directions on both sides of the placement table. A front-back telescopic mechanism for the front-back telescopic movement of the clamping seat and a left-right telescopic mechanism for the left-right telescopic movement of the clamping seat are arranged on the vehicle body. The clamping seats arranged on both sides of the placement table cooperate with the front-back telescopic mechanism for the front-back telescopic movement of the clamping seat and the left-right telescopic mechanism for the left-right telescopic movement of the clamping seat to effectively realize the restraint of the dinner plate placement rack, thereby ensuring its stability during movement.

[0004] Although the existing material conveying AGV automatic guiding vehicle can ensure the stability of materials such as dinner plate placement racks during movement, when the AGV automatic guiding vehicle is applied to processing industries such as workshops or factories, the above AGV automatic guiding vehicle still has the following defects: Since there are many types of materials in the workshop, such as bent pipe or bent rod materials of different sizes, straight rod materials with different placement angles with the ground, etc., the AGV automatic guiding vehicle is required to meet the conditions for transporting the above different types of materials. However, the current AGV automatic guiding vehicle can only transport materials of the same shape or placement angle and cannot adaptively adjust the fixed angle or fixed position according to the shape size and placement angle of the material or the conveying object.

The base is fixedly connected to the L-shaped frame 412. An electric control switch is provided at the connection between the wire and the electromagnet. The electric control switch is communicatively connected to the electric control module 25. When the electric control module 25 controls the electric control switch to turn on, the electromagnet is in an energized state. At this time, the electromagnet module 415 is magnetically attached to the magnetic ring 436, and the third transmission gear 434 is disengaged from the third meshing tooth 334. When the electric control module 25 controls the electric control switch to turn off, the electromagnet is in a de-energized state, and the elastic force of the return spring 416 drives the third transmission gear 434 to fit with the limit cushion block 435. At this time, the third transmission gear 434 is in transmission connection with the third meshing tooth 334.

[0065] Working principle: When the automatic guided vehicle 1 automatically moves to the position of the material 8, the first drive module 21 controls the 360-degree steering mechanism 2 to rotate through the first transmission gear 27, so as to adjust the horizontal positions of the first adjustment mechanism 4 and the second adjustment mechanism 5 according to the position of the material 8.

[0066] Reference appendix Figure 1, when the material 8 is a bent pipe or a bent rod located on the material rack, first use the first telescopic member 314 to control the movement of the second drive module 311, the drive rod 312, and the driving gear 313 until the first engaging tooth 321 is in transmission connection with the driving gear 313. Then, control the electromagnet module 415 to be energized. After being energized, the electromagnet module 415 is magnetically attached to the magnetic ring 436. Since the first key bar 316 is disengaged from the first key groove 332 at this time, when the second drive module 311 controls the rotation of the annular housing 32 through the drive rod 312, the driving gear 313, and the first engaging tooth 321, the rotating annular housing 32 controls the first adjustment mechanism 4 and the second adjustment mechanism 5 to rotate around the fixed shaft 23 in a direction approaching or moving away from each other through the second engaging tooth 322 and the second transmission gear 414. Since the third transmission gear 434 is disengaged from the third engaging tooth 334 at this time, the third transmission gear 434 will not rotate on its own. Thus, the angle between the first anti-detachment mechanism 6 and the second anti-detachment mechanism 7 can be adjusted according to the curvature of the bent pipe or the bent rod. Then, use the second telescopic member 421 to control the telescopic plate 423 to perform a linear motion along the linear guide 411 respectively to adjust the positions of the first anti-detachment mechanism 6 and the second anti-detachment mechanism 7 according to the curvature of the bent pipe or the bent rod until the bent pipe or the bent rod stops between the two first anti-detachment plates 611. Immediately afterwards, use the first telescopic member 314 to control the driving gear 313 to disengage from the first engaging tooth 321 and control the electromagnet module 415 to be powered off. Since the first key bar 316 is located in the first key groove 332 at this time, when the second drive module 311 controls the rotation of the hollow worm 331 through the drive rod 312, the first key bar 316, and the first key groove 332, the rotating hollow worm 331 controls the rotation of the worm gear 333. Since the elastic force of the return spring 416 drives the third transmission gear 434 to be in contact with the limit cushion block 435, the third transmission gear 434 is in transmission connection with the third engaging tooth 334. Therefore, the rotating worm gear 333 controls the two first anti-detachment plates 611 to rotate around the rotating shaft 614 in a direction approaching each other through the third engaging tooth 334 and the third transmission gear 434. The two first anti-detachment plates 611 can prevent the bent pipe or the bent rod from falling off, realizing the function of transporting bent pipes or bent rods with different curvatures.

[0067] Reference appendix Figure 23, when the material 8 is a columnar part, taking the columnar part vertically placed on the ground as an example, first use the above operation method to control the first adjustment mechanism 4 and the second adjustment mechanism 5 to adjust to the horizontal state with the fixed shaft 23 as the axis. When the columnar part presents a certain inclination angle with the ground, adjust the angles of the first adjustment mechanism 4 and the second adjustment mechanism 5 according to the inclination angle.
