Description

Technical Field

[0001] This utility model relates to the field of automation technology, and in particular to a material roll transfer device. Background Technology

[0002] In the production and processing of products such as lithium batteries, stock rolls are an indispensable key material. Currently, the industry commonly uses Automated Guided Vehicles (AGVs) to handle the transfer of stock rolls between storage and unloading stations. AGVs typically transport full stock rolls from the storage area to a designated unloading station on the production line, then remove empty stock rolls from that station and finally return them to the storage station. In other words, empty and full stock rolls are exchanged at both the storage and unloading stations.

[0003] Currently, AGVs must follow a "first-out, then-in" physical sequence when performing loading and unloading operations. That is, empty or full rolls on the AGV must be removed before a new full or empty roll can be received. In actual operation, the replacement process of empty and full rolls is prone to mutual interference, leading to inefficient workflows, increased waiting times, and even equipment downtime, severely restricting the improvement of production cycle time. Utility Model Content

[0004] Therefore, it is necessary to provide a material roll transfer device that facilitates the replacement of empty and full material rolls to address the above problems.

[0005] A coil transfer device, comprising:

[0006] Automated Guided Vehicle;

[0007] A first support mechanism is installed on the base of the automated guided vehicle, and the first support mechanism includes a first bracket;

[0008] A side-sliding mechanism, installed on the base of the automated guided vehicle; and

[0009] The second support mechanism is installed at the moving end of the sliding mechanism. The sliding mechanism can drive the second support mechanism to extend or retract laterally relative to the base. The second support mechanism includes a lifting assembly and a second bracket, with the second bracket installed at the moving end of the lifting assembly.

[0010] In one embodiment, the first support mechanism further includes two spaced-apart uprights that extend vertically from the surface of the base, and the top of each of the two uprights is provided with the first bracket.

[0011] In one embodiment, the distance between the two uprights is adjustable.

[0012] In one embodiment, both the first bracket and the second bracket are formed with V-shaped slots.

[0013] In one embodiment, the inner wall of the slot is provided with an anti-slip pad layer.

[0014] In one embodiment, the side-sliding mechanism includes a base and a side-sliding drive assembly. Telescopic guide rails are provided on opposite sides of the base. The second support mechanism is slidably mounted on the telescopic guide rails and connected to the side-sliding drive assembly.

[0015] In one embodiment, the side-slip drive assembly includes a first motor screw pair structure and a first scissor link, one end of the first scissor link being connected to the first motor screw pair structure and the other end being connected to the second support mechanism.

[0016] In one embodiment, the lifting assembly includes a base plate, a second motor screw pair structure, and a second scissor link. The base plate is mounted on the moving end of the side sliding mechanism, the second motor screw pair structure is mounted on the base plate, one end of the second scissor link is connected to the second motor screw pair structure, and the other end is connected to the second bracket.

[0017] In one embodiment, the lifting assembly includes a base plate, and the second support mechanism further includes two third brackets, which are mounted on the base plate and spaced apart, with the second bracket located between the two third brackets.

[0018] In one embodiment, the orthographic projection of the second support mechanism in its retracted state lies within the range of the base in a direction perpendicular to the surface of the base.

[0019] The aforementioned coil transfer device features an automated guided vehicle that can move back and forth between the storage and unloading stations. The first tray carries full coils, while the second tray carries empty coils. A side-sliding mechanism drives the second support mechanism to extend laterally, and a lifting assembly elevates the second tray, moving it away from the first support mechanism. This spatially separates the loading and unloading operations for full and empty coils. Therefore, while the second tray receives or transfers an empty coil, the first tray can simultaneously receive or transfer a full coil, thus resolving the interference and waiting issues during the replacement of empty and full coils. This significantly improves the efficiency of coil changing and the operating cycle of the automated production line. Attached Figure Description

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0031] Please see Figure 1 and Figure 2 In a preferred embodiment of the present invention, the material roll transfer device 10 includes an automatic guide vehicle 100, a first support mechanism 200, a side sliding mechanism 300, and a second support mechanism 400.

[0032] The automated guided vehicle 100 can travel along a pre-planned path, and as the automated guided vehicle 100 operates, the material roll transfer device 10 can move back and forth between the storage station for storing material rolls and the unloading station for using material rolls, thereby realizing the transfer of material rolls. In the field of lithium battery production, material rolls can be electrode rolls, separator rolls, etc. The automated guided vehicle 100 typically has a chassis and a base, with the base mounted on the chassis to provide ample installation space for other components.

[0033] The first support mechanism 200 is mounted on the base of the automated guided vehicle 100. The first support mechanism 200 includes a first bracket 210. At least two first brackets 210 are provided, each capable of supporting the material shafts at both ends of the material roll. Specifically, the first support mechanism 200 is used to support a full material roll. Due to the large weight of a full material roll, in order to keep the center of gravity of the material roll transfer device 10 stable, the first support mechanism 200 is generally centrally located on the base.

[0034] Specifically, in this embodiment, the first bracket 210 has a V-shaped slot (not shown in the figure). The slot opens upwards, and the space inside the slot gradually narrows from top to bottom. This allows the material roll's spool to be easily placed into the slot, and as the roll falls, the slot gradually locks the spool in place, effectively preventing the full roll from shaking during transfer.

[0035] Furthermore, in this embodiment, the inner wall of the slot of the first bracket 210 is provided with an anti-slip pad layer (not shown in the figure). This anti-slip pad layer can be a rubber layer or a foam layer, which can increase the friction between the inner wall of the slot and the material shaft of the roll, and can further prevent the full roll from shaking during the transfer process.

[0036] A side-sliding mechanism 300 is mounted on the base of the automated guided vehicle 100, while a second support mechanism 400 is mounted on the moving end of the side-sliding mechanism 300. The second support mechanism 400 is used to carry empty coils. Furthermore, the side-sliding mechanism 300 can drive the second support mechanism 400 to extend or retract laterally relative to the base. Lateral extension of the base refers to a direction approximately parallel to the base's bearing surface. Figure 1 The left and right directions are shown.

[0037] When the material roll transfer device 10 moves to the storage station or the unloading station, the second support mechanism 400 is in an extended state to facilitate receiving or transferring empty material rolls. During the operation of the automated guided vehicle 100, the second support mechanism 400 is in a retracted state. Specifically, in this embodiment, in the direction perpendicular to the base surface, the orthographic projection of the retracted second support mechanism 400 lies within the range of the base.

[0038] In other words, during the operation of the automated guided vehicle 100, the second support mechanism 400 will not exceed the inherent contour of the automated guided vehicle 100, so the volume will not increase significantly relative to the automated guided vehicle 100 due to the setting of the side sliding mechanism 300 and the second support mechanism 400. Therefore, there is no need to redesign the original running path of the automated guided vehicle used for material roll transfer.

[0039] Please refer to the following: Figure 4 The second support mechanism 400 includes a lifting assembly 410 and a second bracket 420, with the second bracket 420 mounted on the movable end of the lifting assembly 410. The lifting assembly 410 can drive the second bracket 420 to rise and fall, with its rising and falling direction approximately perpendicular to the direction of the base bearing surface. Figure 1 The up and down directions are shown.

[0040] Similarly, at least two second brackets 420 are provided, each capable of supporting the material shafts at both ends of the material roll. To facilitate connection between the second brackets 420 and the lifting assembly 410, the second support mechanism 400 generally also includes a mounting plate 440. At least two second brackets 420 are fixedly mounted on the mounting plate 440, which is connected to the moving end of the lifting assembly 410.

[0041] The second bracket 420 can adopt the same structure as the first bracket 210. Specifically, in this embodiment, the second bracket 420 forms a V-shaped groove. The opening of the groove faces upward and gradually narrows from top to bottom. Furthermore, the inner wall of the groove of the first bracket 210 is provided with an anti-slip pad layer (not shown in the figure). This anti-slip pad layer can be a rubber layer or a foam layer, which can increase the friction between the inner wall of the groove and the material shaft of the roll. Thus, the second support mechanism 400 can also effectively prevent the empty roll from shaking during the transfer process.

[0042] When the material roll transfer device 10 transfers a full roll to the unloading station, the side-sliding mechanism 300 first drives the second support mechanism 400 to extend laterally, and then the lifting component 410 lifts the second bracket 420, which can then receive empty rolls on the production line. Once the empty roll is received by the second bracket 420, the roll-changing mechanism (not shown) can remove the full roll from the first bracket 210 and load it onto the production line. During the roll-changing process, the lifting component 410 and the side-sliding mechanism 300 can be reset sequentially. When the material roll transfer device 10 transfers an empty roll to the storage station, the side-sliding mechanism 300 again drives the second support mechanism 400 to extend laterally, and the lifting component 410 lifts the second bracket 420 again, allowing the second bracket 420 to transfer the empty roll. At the same time, the loading mechanism (not shown) can place a new full roll on the first bracket 210.

[0043] With the assistance of the side-sliding mechanism 300, the second support mechanism 400 can be moved away from the first support mechanism 200, thus enabling spatial separation of loading and unloading operations for full and empty rolls. Therefore, when the second bracket 420 receives or transfers an empty roll, the first bracket 210 can simultaneously receive or transfer a full roll, thereby solving the problems of mutual interference and waiting during the replacement of empty and full rolls, and significantly improving the efficiency of material changing and the operating cycle of the automated production line.

[0044] Please refer to it again. Figure 1 and Figure 2 In this embodiment, the first support mechanism 200 further includes two spaced-apart uprights 220, which extend vertically from the surface of the base, and the tops of the two uprights 220 are respectively provided with first brackets 210. The uprights 220 can increase the height of the first brackets 210 relative to the base, so the first brackets 210 and the second brackets 420 can have a large height difference. Thus, without interfering with each other, the distance between the first support mechanism 200 and the second support mechanism 400 can be set to be smaller, thereby making the structure of the material roll transfer device 10 more compact.

[0045] Furthermore, in this embodiment, the distance between the two upright plates 220 is adjustable. Specifically, multiple different mounting holes can be provided on the base of the automated guided vehicle 100, and the upright plates 220 can be installed in different mounting holes using threaded fasteners to adjust the distance between the two upright plates 220. By adjusting the distance between the two upright plates 220, the distance between the first brackets 210 can be adapted to material rolls of different lengths, thereby improving the compatibility of the material roll transfer device 10.

[0046] Please refer to the following: Figure 3 In this embodiment, the sliding mechanism 300 includes a base 310 and a sliding drive assembly 320. Telescopic guide rails 311 are provided on opposite sides of the base 310. The second support mechanism 400 is slidably mounted on the telescopic guide rails 311 and connected to the sliding drive assembly 320. The sliding drive assembly 320 can drive the second support mechanism 400 to reciprocate relative to the base 310, causing the second support mechanism 400 to extend or retract laterally relative to the base. Furthermore, the telescopic guide rails 311 on both sides of the base 310 provide stable support for the second support mechanism 400, improving its stability when in the extended state.

[0047] Furthermore, in this embodiment, the side-slip drive assembly 320 includes a first motor screw pair structure 321 and a first scissor link 322. One end of the first scissor link 322 is connected to the first motor screw pair structure 321, and the other end is connected to the second support mechanism 400. The first motor screw pair structure 321 can drive the first scissor link 322 to extend and retract, thereby driving the second support mechanism 400 to slide.

[0048] Specifically, the first motor lead screw pair structure 321 typically includes a motor, a lead screw, a lead screw nut, and a slider. The slider is hinged to one end of the first scissor-type connecting rod 322 and can be mounted on the base 310 via a linear guide. The slider slides along the linear guide, which drives the first scissor-type connecting rod 322 to extend and retract. The first scissor-type connecting rod 322 includes multiple cross-hinged connecting rods, which have strong stability and occupy less space when retracted. Moreover, when using the first scissor-type connecting rod 322 for transmission, the first motor lead screw pair structure 321 can be arranged perpendicular to the extension and retraction direction of the first scissor-type connecting rod 322, that is, the first motor lead screw pair structure 321 can be arranged laterally, thus allowing the first motor lead screw pair structure 321 to be installed in a smaller space.

[0049] It should be noted that in other embodiments, the second support mechanism 400 may also be directly driven by a cylinder or a motor screw pair.

[0050] Please refer to it again. Figure 4 In this embodiment, the lifting assembly 410 includes a base plate 411, a second motor screw pair structure 412, and a second scissor link 413. The base plate 411 is installed on the moving end of the side sliding mechanism 300, the second motor screw pair structure 412 is installed on the base plate 411, one end of the second scissor link 413 is connected to the second motor screw pair structure 412, and the other end is connected to the second bracket 420.

[0051] Specifically, the second motor lead screw pair structure 412 can adopt the same structure as the first motor lead screw pair structure 321; the second scissor link 41 can also adopt the same structure as the first scissor link 322, the difference being the number of links. The second motor lead screw pair structure 412 can drive the second scissor link 413 to extend and retract, thereby driving the second bracket 420 to lift and lower. Similarly, the second scissor link 413 occupies less space when retracted and allows the second motor lead screw pair structure 412 to be arranged laterally, thus making the structure of the second support mechanism 400 more compact.

[0052] Furthermore, in this embodiment, the second support mechanism 400 also includes two third brackets 430, which are mounted on the base plate 411 and spaced apart. The second bracket 420 is located between the two third brackets 430. The third brackets 430 are not located at the moving end of the lifting assembly 410, and therefore do not move up or down with the second bracket 420.

[0053] The third bracket 430 can also carry empty coils, and compared to the second bracket 420, the third bracket 430 can contact the outer side of the coil shaft, improving the stability of the support. Moreover, when the second bracket 420 lifts the coil, the area where the coil shaft originally contacted the third bracket 430 is exposed, thus facilitating the loading and unloading of empty coils.

[0054] The aforementioned material roll transfer device 10, with its automated guided vehicle 100 capable of moving back and forth between the storage station and the unloading station, features a first bracket 210 for carrying full material rolls and a second bracket 420 for carrying empty material rolls. A side-sliding mechanism 300 drives a second support mechanism 400 to extend laterally, and a lifting assembly 410 lifts the second bracket 420, thus moving the second support mechanism 400 away from the first support mechanism 200. This spatially separates the loading and unloading operations for full and empty material rolls. Therefore, when the second bracket 420 receives or transfers an empty material roll, the first bracket 210 can simultaneously receive or transfer a full material roll, thus solving the problems of mutual interference and waiting during the replacement of empty and full material rolls, significantly improving the efficiency of material changing and the operating cycle of the automated production line.

[0055] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
