Example 1

Referring to fig. 1 and 2, the present embodiment provides an AGV fixing device 100, which includes a bracket 110 and a first guide rail 120. Wherein the first guide rail 120 is provided on the bracket 110, the first guide rail 120 has a first guide surface 121, and the first guide surface 121 is provided obliquely with respect to a horizontal plane.

When the AGV200 (see fig. 4) enters the AGV fixture 100, it contacts the first guide rail 120 and climbs upward under the guidance of the first guide surface 121, thereby being raised into the air. At this time, the AGV200 is not affected by the flatness of the ground, and can be accurately positioned, thereby meeting the high-precision requirement of the manufacturer for the equipment.

Example 2

Referring to fig. 3, the present embodiment provides an AGV fixing device 100, which includes a bracket 110, a first rail 120, a second rail 130, a third rail 140, a limiting member 150 and a clamping mechanism 160. The first rail 120, the second rail 130, the third rail 140, the limiting member 150 and the clamping mechanism 160 are disposed on the bracket 110.

Referring to fig. 4, when the AGV200 enters the AGV fixture 100, the first guide rail 120 and the second guide rail 130 guide the AGV200 to climb upward, and the third guide rail 140 guides the AGV200 to be aligned with the AGV fixture 100. The stop 150 intercepts the AGV200, stops the AGV200 from traveling, and cooperates with the clamping mechanism 160 to secure the AGV 200.

Referring to fig. 3 again, specifically, the support 110 is composed of a bottom plate 111 and legs 112.

The base plate 111 is anchored to the ground by anchor bolts, the legs 112 are bolted to the base plate 111, and the first rail 120, the second rail 130, the third rail 140, the limiting member 150 and the clamping mechanism 160 are supported by the legs 112.

The base plates 111 and the legs 112 are divided into two groups, and each group of base plates 111 and legs 112 is fixed with a first guide rail 120, a second guide rail 130, a third guide rail 140, a limiting member 150 and a clamping mechanism 160, which are respectively matched with two sides of the AGV 200.

Referring to fig. 4 and 5, in particular, the first guide rail 120, the second guide rail 130 and the third guide rail 140 are all disposed along a first direction. The third rail 140 is bolted to the leg 112, and the first rail 120 and the second rail 130 are bolted to the third rail 140.

The first direction is the direction of travel of the AGV200, and is shown in the x direction.

Specifically, the first guide rail 120 has a first guide surface 121 and a first bearing surface 122.

In the present embodiment, the first guide surface 121 is a flat surface, and the first guide surface 121 is disposed obliquely to the horizontal plane. The height of the first guide surface 121 gradually increases in the first direction.

The first bearing surface 122 is horizontal, and the first bearing surface 122 is connected to the top end of the first guide surface 121.

When the AGV200 enters the AGV fixture 100, it contacts the first guide surface 121 and climbs up the first guide surface 121 to be raised into the air until contacting the first support surface 122. At this point, the AGV200 is hovering at a particular height, and its weight is borne primarily by the first bearing surface 122, independent of the flatness of the ground.

The flatness of the ground is difficult to guarantee, and in contrast, the first guide surface 121 can be leveled by adjusting the first guide rail 120, so that accurate positioning can be realized, and the requirement of manufacturers on high precision of equipment can be met.

In another embodiment of the present application, the first guide surface 121 may also be an arc surface gradually rising in the first direction.

In another embodiment of the present application, the AGV200 may be held on the first guide surface 121 by applying a force to the AGV200 in the first direction, instead of providing the first bearing surface 122.

Specifically, the second guide rail 130 is located forward of the first guide rail 120 in the first direction, and the second guide rail 130 has a second guide surface 131 and a second bearing surface 132.

In this embodiment, the second guide surface 131 is a flat surface, and the second guide surface 131 is disposed obliquely to the horizontal surface. The height of the second guide surface 131 gradually increases in the first direction. Further, the second guide surface 131 is provided in parallel to the first guide surface 121, and the bottom end of the second guide surface 131 is not lower than the top end of the first guide surface 121.

The second bearing surface 132 is horizontal, and the second bearing surface 132 is connected to the top end of the second guide surface 131.

Similarly, when the AGV200 is driven into the AGV fixture 100, it contacts the second guide surface 131 and climbs up the second guide surface 131, thereby being lifted into the air until contacting the second support surface 132. At this time, the AGV200 is suspended at a specific height, and the weight of the AGV is mainly borne by the second bearing surface 132, so that the AGV is not affected by the flatness of the ground, and can be accurately positioned, thereby meeting the requirement of a manufacturer on the high precision of equipment.

The first guide rail 120 and the second guide rail 130 are simultaneously provided such that the first guide surface 121 is parallel to the second guide surface 131 and the second guide surface 131 is higher than the first guide surface 121. When the AGV200 enters the AGV fixture 100, the front end of the AGV200 passes over the first guide surface 121 and continues to travel. When the front end of the AGV200 contacts the second guide surface 131, the rear end of the AGV200 just contacts the first guide surface 121. Thereafter, the AGV200 climbs along the first guide surface 121 and the second guide surface 131 simultaneously, and can be kept stable during climbing, so as to avoid deviation of parts on the AGV200 from the original position due to inclination. Finally, the front end of the AGV200 moves onto the second supporting surface 132, the rear end of the AGV200 moves onto the first supporting surface 122, and the weight of the AGV200 is borne primarily by the first supporting surface 122 and the second supporting surface 132.

Specifically, the third guide rail 140 has a third guide surface 141.

The third guide surfaces 141 are provided to be inclined with respect to the first direction, and the third guide surfaces 141 of the two third guide rails 140 gradually come closer together in the first direction. Further, the third guide surface 141 is located rearward of the first guide rail 120 in the first direction and contacts the AGV200 before the first and second guide surfaces 121, 131.

If the AGV200 is not perfectly centered with respect to the AGV fixture 100, the AGV200 will contact one of the third guide surfaces 141 when it enters the AGV fixture 100, and will be gradually centered with respect to the AGV fixture 100 under the guidance of the third guide surface 141.

Referring to FIG. 6, specifically, the stop 150 is bolted to the legs 112 and positioned forward of the AGV200 in a first direction. After the AGV200 has traveled in the first direction to abut against the stopper 150, it cannot continue to travel. Thus, the stop 150 is able to position the AGV200 in the first direction.

Further, the stopper 150 has a positioning portion 151. The positioning portion 151 engages with the AGV200 to position the AGV200 in the second direction.

The second direction is horizontal and perpendicular to the first direction, and is indicated by the y direction in the figure.

In this embodiment, the positioning portion 151 is provided as a dovetail shape, and the positioning portion 151 protrudes from the surface of the stopper 150. Accordingly, the AGV200 is provided with a dovetail groove, and the positioning portion 151 is engaged with the dovetail groove.

Referring to fig. 7, specifically, the clamping mechanism 160 is disposed away from the limiting member 150. After the AGV200 abuts against the limiting member 150, the clamping mechanism 160 cooperates with the limiting member 150 to clamp the AGV200, so that the AGV200 and the limiting member 150 are kept abutting, and the AGV200 is fixed.

In this embodiment, the clamping mechanism 160 is composed of a base 161, a cylinder 162, and a clamping jaw 163. The base 161 is bolted and fixed on the supporting leg 112, the cylinder body of the air cylinder 162 and the clamping jaw 163 are both hinged with the base 161, and the piston rod of the air cylinder 162 is also hinged with the clamping jaw 163.

The piston rod of the cylinder 162 extends out to drive the clamping jaw 163 to swing towards the AGV200 until the clamping jaw 163 abuts against one end of the AGV200, which is opposite to the limiting member 150.

Referring to fig. 6 again, further, a proximity switch 113 is further disposed on the leg 112 where the limiting member 150 is located, and the proximity switch 113 is electrically connected to the clamping mechanism 160.

When the AGV200 abuts the limit stop 150, the proximity switch 113 senses the arrival of the AGV200 and outputs a signal to the clamping mechanism 160. Upon receiving the signal, the clamping mechanism 160 operates to clamp the AGV 200.

In the present embodiment, the proximity switch 113 is a travel switch.

In another embodiment of the present application, the proximity switch 113 may also be a photosensor.

Further, a buffer 114 is disposed on the leg 112 where the stopper 150 is located, and the buffer 114 contacts the AGV200 before the stopper 150.

The buffering member 114 is provided to reduce the collision between the AGV200 and the limiting member 150, so as to prevent the limiting member 150 from deforming, and ensure that the limiting member 150 can accurately position the AGV 200.

In the present embodiment, the buffer member 114 is composed of a rubber block and a connecting rod. The rubber block is connected to the legs 112 through the connecting rods, and contacts the AGV200 before the stoppers 150 when the AGV200 arrives, thereby performing an elastic buffering function.

When the AGV200 enters the AGV fixture 100, it first contacts the third guide rail 140, and is centered with the AGV fixture 100 under the guidance of the third guide surface 141, and then contacts the first guide rail 120 and the second guide rail 130, and climbs upward under the guidance of the first guide surface 121 and the second guide surface 131, and thus rises into the air. At this time, the AGV200 is not affected by the flatness of the ground, and can be accurately positioned, thereby meeting the high-precision requirement of the manufacturer for the equipment.

Example 3

Referring to fig. 4 and 8, the present embodiment provides a logistics handling system, which includes AGVs 200 and the AGV fixing device 100.

Specifically, the AGV200 is comprised of a frame 210, a first guide wheel 220, a second guide wheel 230, and a third guide wheel 240, with the first guide wheel 220, the second guide wheel 230, and the third guide wheel 240 all being disposed on the frame 210.

The first guide wheel 220 is engaged with the first guide rail 120, the second guide wheel 230 is engaged with the second guide rail 130, and the third guide wheel 240 is engaged with the third guide rail 140, so as to reduce the resistance of the AGV200 during climbing and centering.

In addition, the first guide wheel 220 is lower than the second guide wheel 230, and the height difference between the first guide wheel 220 and the second guide wheel 230 is equal to the height difference between the first bearing surface 122 and the second bearing surface 132.
