Description

Technical Field

[0001] The utility model relates to the technical field of pole roll conveying, in particular to a pole roll buffer rack used for AGV positioning. Background Art

[0002] The pole roll buffer rack can improve the efficiency and accuracy of warehouse management. By using the pole roll buffer rack positioned by AGV, automated warehouse operations can be achieved, manual operations and errors can be reduced, and the speed and accuracy of material flow can be improved.

[0003] At present, AGVs are mostly used to transport pole coils in battery cell production bases, and most AGVs are laser-guided AGVs. However, when the pallet is placed on the buffer rack, due to the heavy weight of the pallet carrying the pole coil, positioning deviation often occurs, resulting in two adverse consequences. First, the pallet is tilted on the buffer rack. When the AGV comes to pick up materials next time, the pallet on the AGV will be tilted to one side, and it is very easy to fall when the AGV is transporting or turning, causing damage to the pallet or the ground; second, the pallet is directly dumped when the AGV is placed on the buffer rack, causing the pole coil to slip and be damaged. The pole cloth has extremely high requirements for flatness, and the fallen pole coils are often unable to be used again, resulting in huge cost losses. Utility Model Content

[0004] In order to solve the above technical problems, the utility model uses a positioning piece to be connected with a positioning hole to accurately position the tray with the pole coil on the buffer rack. The specific technical solution is as follows:

[0005] A pole coil cache rack for AGV positioning includes a cache rack open at one end in the horizontal direction, the top surface of which is used to place a tray with pole coils, the top surface of the cache rack is provided with at least two positioning holes, the bottom surface of the tray is provided with positioning pieces corresponding to the positioning holes, and the tray is limited by the positioning pieces and the positioning holes.

[0006] Preferably, both the positioning member and the positioning hole are cone-shaped, and the cone size of the positioning member is at least larger than the cone size of the positioning hole.

[0007] Preferably, the positioning member is in the shape of a water drop, and the head end is along the force direction of the tray on the cache rack, and the positioning hole and the positioning member are mutually engaged.

[0008] Preferably, the positioning member and the positioning hole are truncated cone-shaped.

[0009] Preferably, the junction between the positioning hole and the top surface of the cache rack is inclined.

[0010] Preferably, the top surface of the cache rack is tilted along the moving direction of the tray with the positioning hole as the center, and the top of the positioning hole is lower than the top surface of the cache rack.

[0011] It can be seen from the above technical solutions that the utility model has the following beneficial effects:

[0012] The utility model places the pallet on the cache rack, and the positioning piece and the positioning hole adapt to each other, and the positioning piece is clamped with the positioning hole, so as to accurately position the pallet with the pole coil on the cache rack, and has good auxiliary, error correction and reminder functions, thereby reducing the cost of pole coil damage and pallet and ground damage caused by positioning errors between the pallet and the cache rack transported by AGV in the battery production workshop.

[0017] The following is a detailed description of the present invention in conjunction with the accompanying drawings and specific embodiments. Before describing in detail the technical solutions of each embodiment of the present invention, the nouns and terms involved are explained. In this specification, components with the same name or the same number represent similar or identical structures and are only for illustrative purposes.

[0018] like Figure 1 and Figure 2 As shown, a pole roll cache rack for AGV positioning includes a cache rack 1 with one end open in the horizontal direction, a base 5 is also installed at the bottom end of the cache rack 1, and the base 5 can be made of rubber to reduce the position stability of the cache rack 1. The top surface of the cache rack 1 is used to place a tray 11 with a pole roll 10. The top surface of the cache rack 1 is provided with at least two positioning holes 3, and the bottom surface of the tray 11 is provided with a positioning piece 9 corresponding to the positioning hole 3. The tray 11 is limited by the positioning piece 9 and the positioning hole 3. The side wall of the cache rack 1 is provided with a lightweight hole 2 for reducing the weight of the cache rack 1 and saving materials. Among them, the cache rack 1 is open at one end in the horizontal direction, which is convenient for the AGV to move the tray 11 and the pole roll 10 from the open end to the cache rack 1. The number of positioning holes 3 can be set to multiple, preferably four, respectively located around the tray 11, so as to improve the limiting effect of the tray 11, and then improve the positioning effect of the pole roll 10.

[0019] Embodiment 1:

[0020] like Figure 1 and Figure 2 As shown, the positioning member 9 and the positioning hole 3 are both in the shape of a cone, and the cone size of the positioning member 9 is at least larger than the cone size of the positioning hole 3, wherein the positioning member 9 is in the shape of a cone and is inserted into the positioning hole 3, and the tray 11 can automatically return to its original position with the positioning hole 3 through the side wall of the cone, and automatically correct the deviation to ensure that the tray 11 can accurately fall onto the cache rack 1, and the size of the positioning member 9 can be larger than the size of the positioning hole 3. At this time, a gap may be created between the tray 11 and the cache rack 1, but the size of the positioning member 9 cannot be too large than the positioning hole 3. The height of the cone of the positioning member 9 is at most twice that of the cone of the positioning hole 3. If the size of the positioning member 9 is too large, the tray 11 may easily detach from the positioning hole 3.

[0021] Embodiment 2:

[0022] The positioning member 9 is in the shape of a water drop, and the head end is along the force direction of the tray 11 on the cache rack 1, and the positioning hole 3 and the positioning member 9 are clamped together. Among them, since the head end of the water drop shape is larger than the tail end, the head of the positioning member 9 and the positioning hole 3 are clamped together, and the bottom end of the positioning hole 3 is the same as the head end of the water drop shape, and the positioning hole 3 is tilted outward from the bottom end to the top end, which is convenient for the water drop shape positioning member 9 to be clamped into the positioning hole 3, and the positioning member 9 has the effect of automatic return to its original position, and the water drop shape positioning member 9 can increase the force effect between it and the cache rack 1.

[0023] Embodiment three:

[0024] The positioning member 9 and the positioning hole 3 are in the shape of a truncated cone, wherein the bottom end of the truncated cone is in contact with the top surface of the cache rack 1, which can increase the contact area of ​​the cache rack 1 with the tray 11. Compared with the first embodiment, it can avoid excessive wear of the cone due to long-term use, which can easily cause the tray 11 to tilt during movement and cause the pole roll 10 to fall off.

[0025] like Figure 1 and Figure 2 As shown, the intersection of the positioning hole 3 and the top surface of the cache rack 1 is inclined, wherein, since the edge of the positioning hole 3 is inclined, the positioning member 9 can automatically correct the deviation by gravity to ensure that the tray 11 carrying the pole roll 10 can be accurately positioned on the cache rack 1.

[0026] The top surface of the cache rack 1 is inclined along the moving direction of the tray 11 with the positioning hole 3 as the center, and the top of the positioning hole 3 is lower than the top surface of the cache rack 1. When the AGV transports the tray 11 to the top surface of the cache rack 1, the positioning member 9 contacts the inclined slope, and the slope contacts the bottom surface of the positioning member 9. Due to the effect of gravity, the positioning member 9 will gradually move to the positioning hole 3 and automatically fall into the positioning hole 3. For the above-mentioned embodiments one and two, the side edges are inclined, and the tangent of the bottom end can be colinear with the inclined slope of the cache surface 1 to improve the guiding effect. For embodiment three, the bottom end cone of embodiment three can be fitted with the inclined surface of the cache rack 1 to improve the fitting and guiding effects.

[0027] like Figure 3 As shown, a reflective baffle 4 is installed at the open end of the cache rack 1, wherein the reflective baffle 4 can reflect the laser, the cache rack 1 and the tray 11 carrying the pole roll 10. When the AGV arrives in front of the cache rack 1 according to the set route, it is necessary to transfer the tray 11 carrying the pole roll 10 to the cache rack 1. The laser transmitter on the AGV will emit a laser beam, and after interacting with the laser reflective baffle 4 on the cache rack 1, the AGV on-board computer calculates the current relative position with the cache rack 1 and corrects the posture according to the set docking parameters.

[0028] Further, such as Figure 1-Figure 3 As shown, the AGV will pass through the soft laser reflective baffle 4, arrive under the cache rack 1, and place the tray 11 on the cache rack 1. At this time, the positioning piece 9 at the bottom of the tray 11 will be inserted into the positioning hole 3 on the cache rack 1.

[0029] When the AGV is withdrawn from the bottom of the cache rack 1, it will also pass through the soft reflective baffle 4. When the AGV completely leaves the cache rack 1, the soft reflective baffle 4 will automatically reset due to gravity.

[0030] In addition to the above-mentioned positioning using laser and reflective baffle 4, AGV can also use visual positioning and ultrasonic positioning. If ultrasonic positioning is used, the AGV calculates its own position by emitting ultrasonic signals and using ultrasonic sensors to receive reflected signals; if visual positioning is used, the AGV uses visual sensors such as cameras and image processing algorithms to extract feature points in the environment to determine its own position.

[0031] An indicator light 6 is provided at one end of the cache rack 1, and a wire tube 7 is fixedly installed at the end of the cache rack 1. The indicator light 6 is fixedly installed on the wire tube 7, and a light switch 8 is also installed on the wire tube 7. Furthermore, when the positioning piece 9 on the tray 11 is completely and closely combined with the positioning hole 3 on the cache rack 1, the indicator light 6 on the right outer side of the tray 11 will be green, indicating accurate positioning; when the positioning piece 9 on the tray 11 is misaligned with the positioning hole 3 on the cache rack 1, the indicator light 6 will be red, and human intervention is required to correct the position of the tray 11 carrying the pole roll 10 to prevent the pole roll 10 and the tray 11 from falling, or after the AGV comes to pick up the material, the posture of the tray 11 on the AGV is skewed, causing the tray 11 to slip during transportation by the AGV, and when the indicator light 6 is yellow, it indicates that the cache rack 1 is in an empty material calling state.

[0032] Furthermore, when the AGV comes to pick up the empty pallet 11, the above-mentioned actions are repeated to transport the empty pallet 11 to the designated location for loading.

[0033] In summary, the cache rack 1 used by the laser-guided AGV of the utility model has a good auxiliary, error correction and reminder effect for the accurate positioning of the pole roll 10 pallet 11 on the cache rack 1, thereby reducing the cost of damage to the pole roll 10 and damage to the pallet 11 and the ground in the battery cell production workshop due to the positioning error between the pallet 11 transported by the AGV and the cache rack 1.

[0034] The above-described embodiments are merely descriptions of preferred embodiments of the present invention, and are not intended to limit the scope of the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solutions of the present invention by ordinary technicians in this field should all fall within the protection scope determined by the claims of the present invention.
