[0029] The technical solution protected by this utility model will be described in detail below with reference to the accompanying drawings.

[0030] like Figure 1-2 As shown, this application proposes an AGV (Automated Guided Vehicle) trolley for loading and unloading materials, which includes a vehicle body assembly 1, a lifting execution unit 2, a material conveying unit 3, a positioning unit 4, and a control system 5. The control system 5 is electrically connected to the lifting execution unit 2, the material conveying unit 3, and the positioning unit 4. The vehicle body assembly 1 includes a first side frame 11 and a second side frame 12 spaced apart along the X-axis, and a base frame 13 connecting the first side frame 11 and the second side frame 12. The first side frame 11, the second side frame 12, and the base frame 13 form a U-shaped structure and form a material unloading area.

[0031] like Figure 1-2 As shown, the lifting execution unit 2 includes a vertically lifting loading platform 21 and a lifting drive module 22 that drives the loading platform 21. The loading platform 21 is located within the unloading area, and the lifting drive module 22 is correspondingly mounted on the side frames on both sides. The loading platform 21 is used to carry materials, and the lifting drive module 22 drives the loading platform 21 to move vertically up and down within the unloading area. The docking height can be adjusted according to the height of the loading equipment or the receiving equipment, improving the flexibility of loading and unloading.

[0032] In this embodiment, two sets of lifting drive modules 22 are provided, which are respectively connected to the opposite sides of the loading platform 21 in the X-axis direction, and are used to synchronously lift the loading platform 21 to improve the lifting stability of the loading platform.

[0033] Specifically, the lifting drive module 22 includes a lead screw, a lead screw bearing, a servo motor, and a reducer. The two ends of the lead screw are rotatably connected to the side frames on both sides. The lead screw bearing is located on the side of the loading platform. The lead screw passes through the lead screw bearing and forms a worm gear structure. The servo motor and reducer drive the lead screw to rotate, and the lead screw bearing follows to achieve up and down movement, so as to drive the loading platform 21 to lift synchronously.

[0034] like Figure 1-2 As shown, the material conveying unit 3 includes a roller assembly 31 mounted on the loading platform 21 and a conveying drive module (not shown) that drives the roller assembly 31 to rotate. The roller assembly 31 includes a plurality of rollers arranged sequentially along the Y-axis direction. The conveying drive module drives the plurality of rollers to rotate synchronously to convey the material on the loading platform 21 along the Y-axis direction.

[0035] Preferably, multiple sets of roller assemblies are arranged parallel to each other along the X-axis on the loading platform 21 to improve the stability of material transmission.

[0036] Specifically, the conveyor drive module can be a chain drive, with a sprocket installed at the same end of each roller. A continuous long chain passes around the sprockets of all rollers in sequence, with a drive sprocket at the beginning or end, which is connected to a servo motor and a reducer. In other embodiments, the conveyor drive module can also use a synchronous belt drive, gear drive, or other structures, which are not specifically limited here.

[0037] like Figure 1-2 As shown, the positioning unit 4 includes guide plates 41 on both sides of the loading platform 21 along the X-axis and a positioning baffle 42 on one end of the loading platform 21 along the Y-axis.

[0038] like Figure 1-2 As shown, the guide plate 41 includes a first guide section 411 and a second guide section 412 arranged sequentially along the feeding and conveying direction. The second guide section 412 is parallel to the Y-axis, and the two sets of second guide sections 412 form a second conveying interval. The end of the first guide section 411 away from the second guide section 412 extends obliquely away from the loading platform 21, and the two sets of first guide sections 411 form a first conveying interval. The width of the first conveying interval gradually decreases towards the second conveying interval, and the width of the second conveying interval is greater than the width of the material. The wide entrance (first conveying interval) facilitates material entry, and the gradually narrowing structure guides the material to the precise second conveying interval.

[0039] Preferably, the connection between the first guide section 411 and the second guide section 412 is set as an arc-shaped structure to prevent the material from being hard-damaged by the guide guard plate 41 during the guiding process.

[0040] like Figure 1-3As shown, further, a correction auxiliary unit 413 is provided below the first guide section 411. The correction auxiliary unit 413 includes several auxiliary rollers, which are rotatably mounted on the bottom of the guide guard plate 41. The axis of the auxiliary rollers is perpendicular to the upper end face of the material loading platform 21. The multiple auxiliary rollers are arranged sequentially along the extension direction of the first guide section 411. Some of the auxiliary rollers protrude from the inner side of the guide guard plate 41. When the material is guided and conveyed in the second transmission section, the material contacts the auxiliary rollers, which can reduce friction and improve the smoothness of the guidance.

[0041] Furthermore, such as Figure 1-4 As shown, a correction actuator 43 is provided on one side of the loading platform 21 along the X-axis. The correction actuator 43 includes a correction push block 431 that can move along the X-axis and a linear cylinder 432 that drives the correction push block 431. A clearance hole 414 is provided on the guide plate 41 on the corresponding side for the correction push block 431 to pass through.

[0042] Preferably, the correction pusher 431 can be made of an elastic material to prevent wear on the material caused by hard collision between the correction pusher 431 and the material during the pushing process.

[0043] like Figure 2 As shown, the positioning baffle 42 is equipped with a grating, which is used to detect whether the material has been transferred to the correct position in the Y-axis direction.

[0044] Preferably, a buffer pad 421 is provided on the side end face of the positioning baffle 42 near the loading platform 21. The buffer pad is made of elastic material to prevent the material from having a hard collision with the positioning baffle 42 when it is being loaded.

[0045] The base frame 13 is equipped with drive rollers and a drive source for rotating the drive rollers. The drive source is electrically connected to the control system to drive the AGV trolley to move as a whole.

[0046] like Figure 1-2 As shown, the vehicle body component 1 is covered by an outer shell 6, which is a sheet metal shell. A display screen 61 is mounted on the outer shell 6, and a start / stop switch 62 is located on one side of the display screen 61. A light strip 63 is arranged around the lower circumference of the outer shell 6, and 260° obstacle avoidance laser emitters 64 are located at the four corners of the outer shell. The display screen 61, start / stop switch 62, light strip 63, and obstacle avoidance laser emitters 64 are all electrically connected to the control system 5.

[0047] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
