Description

Technical Field

[0001] The present invention relates to the technical field of transportation equipment, and in particular to an AGV material transfer device. Background Art

[0002] In modern industrial production and logistics warehousing, the efficiency and accuracy of material transfer play a vital role in overall operational efficiency. With the deepening of the concept of intelligent manufacturing, automated guided vehicle (AGV) technology has emerged and been widely used, providing a solution for the intelligent and unmanned transfer of materials.

[0003] Traditional material handling methods mostly rely on manual carts and forklifts, which not only consumes a lot of manpower costs, but also easily lead to low material handling efficiency and high error rates due to factors such as human fatigue and operational errors. Especially in large-scale production workshops or large logistics warehouses, where materials flow frequently and the handling routes are complex, traditional handling methods are increasingly unable to meet the needs of high-speed and precise operations.

[0004] As the core equipment of automated material handling, AGV can autonomously shuttle around the work site according to preset programs and navigation systems, greatly improving the flexibility and autonomy of handling. However, the existing AGV material transfer devices still expose some problems in practical applications. For example, relying solely on the plane transportation function of AGV, there is a lack of sophisticated design in the loading and unloading of materials, and it is often unable to adapt to the efficient handling of materials of different heights and shapes.

[0005] When it comes to scenarios that require precise positioning and placement of materials, ordinary AGV carriers cannot ensure the stability of materials during transportation, which can easily cause materials to shake or shift, thus affecting the accuracy of subsequent processing or storage procedures. In addition, when faced with tasks that require frequent adjustments to the posture or height of materials, existing devices lack flexible adjustment mechanisms and cannot quickly respond to the changing material transfer requirements on the production line. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, the present invention provides an AGV material transfer device, the purpose of which is to solve the problems of precise positioning and posture adjustment in the material transfer process by designing structures such as brackets, motors, screws, pallets, cylinders and drive components on the AGV cart, so as to meet the growing demands for refinement and efficiency in modern industry and logistics.

[0007] In order to achieve the above-mentioned object of the invention, the technical solution adopted by the present invention is:

[0023] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings, wherein the same components are represented by the same reference numerals.

[0024] It should be noted that the words "front", "rear", "left", "right", "up" and "down" used in the following description refer to directions in the drawings, and the words "inside" and "outside" refer to directions toward or away from the geometric center of a specific component, respectively.

[0025] In order to make the contents of the present invention more clearly understood, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] like Figures 1 to 4 As shown, an AGV material transfer device includes an AGV trolley 1, a bracket 2, a motor 3, a screw 4, a tray 5, a cylinder 6, a base plate 7, a material basket 8, a drive assembly 9, and auxiliary components including a first chute 13, a second chute 14, a roller 15, an in-position switch 16 and a display 17.

[0027] The AGV 1 is equipped with a stable power system, an accurate navigation module and a reliable control system, and can autonomously drive in the workplace according to a preset path.

[0028] On the top of the AGV trolley 1, the mounting bracket 2 is fixed by welding to ensure that the bracket 2 is firmly connected to the AGV trolley 1.

[0029] The motor 3 is mounted on the bracket 2. The motor 3 is a servo motor. The output shaft of the motor 3 is fixedly connected to the lead screw 4 through a coupling. The lead screw 4 adopts a high-precision ball screw. The lead screw 4 is connected to the tray 5 through threads.

[0030] When the motor 3 starts to run, it drives the lead screw 4 to rotate. Since the tray 5 is constrained by the first slide groove 13 on the bracket 2, it can only perform a linear lifting motion along the slide groove direction, thereby achieving precise lifting control of the tray 5.

[0031] A cylinder 6 is fixedly mounted on the bottom of the tray 5 by bolts, and the end of the piston rod of the cylinder 6 is hinged to the bottom of the bottom plate 7 by a pin.

[0032] The tray 5 is processed with a second slide groove 14 , and the bottom plate 7 is slidably connected to the second slide groove 14 , so that the bottom plate 7 can slide on the tray 5 in a horizontal direction.

[0033] When the cylinder 6 is extended or retracted, the bottom plate 7 is pushed to slide along the second slide groove 14 , thereby adjusting the lateral position of the bottom plate 7 .

[0034] The material holding basket 8 is hinged to the bottom plate 7 via a hinge, so that the material holding basket 8 can move synchronously with the lateral movement of the bottom plate 7 and can also be flipped at a certain angle relative to the bottom plate 7 to facilitate the dumping of materials or special loading needs.

[0035] The driving assembly 9 is a key part for adjusting the posture of the material basket 8. The first ear seat 10 is fixed to the bottom plate 7 by welding, and the second ear seat 11 is also fixed to the bottom of the tray 5 by a firm connection. The two ends of the electric push rod 12 are respectively hinged with the first ear seat 10 and the second ear seat 11 through a pin shaft to form a triangular structure that can be flexibly rotated. When the electric push rod 12 is extended and retracted, due to the hinge constraints at both ends, it will push the bottom plate 7 to move vertically relative to the tray 5 and change the angle to a certain extent, thereby driving the material basket 8 to achieve complex posture adjustments to meet the special placement requirements in the transportation process of different materials.

[0036] The plurality of rollers 15 evenly distributed and rotatably connected to the tray 5 are made of wear-resistant rubber or nylon material with a small friction coefficient. The rollers 15 are rotatably connected to the tray 5 through bearings and can rotate flexibly.

[0037] When the material basket 8 is placed on the rollers 15 , due to the rolling of the rollers 15 , the friction force on which the material basket 8 is subjected when moving is extremely small, so that it is convenient for the material basket 8 to translate on the tray 5 .

[0038] The in-position switch 16 arranged on the top of the AGV trolley 1 is a high-precision proximity switch. When the AGV trolley 1 moves, the material basket 8 reaches the in-position switch 16 along with the movement of the tray 5 and the bottom plate 7. The in-position switch 16 can quickly sense and transmit the signal to the control system of the AGV trolley 1. The control system stops the action of the motor 3 and the material basket 8 stops moving. When the AGV trolley 1 moves, the material basket 8 moves more smoothly due to its lower position.

[0039] The display 17 provided on the AGV 1 is a liquid crystal display screen, which is connected to the control system of the AGV 1 through a data cable. The display 17 can display the current position, driving speed, lifting height of the tray 5, telescopic state of the cylinder 6, working condition of the electric push rod 12, and progress of material transfer of the AGV 1 in real time, so as to facilitate the operator to remotely monitor the operating status of the device.

[0040] An AGV material transfer device of the present invention can achieve high-precision lifting and lowering of the pallet 5, and can finely adjust the vertical and lateral positions of the materials, ensuring that the materials in the material basket can be accurately positioned at the target position whether they are loaded or unloaded, greatly reducing the deviation in the material transfer process, and effectively avoiding the impact of inaccurate material placement on subsequent processes, facilitating material loading and unloading, and further improving the efficiency and convenience of material transfer.

[0041] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
