DETAILED DESCRIPTION

[0028] In the related art, when producing battery pole pieces, a plurality of different types of rollers need to be used. These rollers are inevitably maintained (i.e., repaired and maintained) during use, so the rollers need to be disassembled from the equipment, and then assembled to the equipment after the maintenance is completed. However, with the increase of the production capacity of battery pole pieces, the rollers are wider and heavier, which increases the labor intensity of workers when disassembling the rollers, and reduces the disassembly efficiency of the rollers, ultimately leading to too long downtime of the equipment, which is not conducive to the continuity of production. Therefore, the present application proposes a roller disassembly device in the following embodiments to solve the above-mentioned drawbacks in the related art.

[0029] In order to make the purposes, technical solutions and advantages of the present application more obvious and easy to understand, the present application will be described clearly and completely below in combination with the embodiments of the present application and corresponding drawings, wherein the same or similar reference signs represent the same or similar elements or elements with the same or similar functions throughout. It should be understood that the embodiments of the present application described below are only used to explain the present application and do not limit the present application, that is, all other embodiments obtained by those skilled in the art without creative labor on the basis of various embodiments of the present application belong to the scope of protection of the present application. In addition, the technical features involved in the various embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0030] Please refer to Figure 1 , Figure 2 and Figure 3 , Figure 1 is a structural schematic view of a roller dismounting device, Figure 2 is a principle view of dismounting a roller by using the roller dismounting device, Figure 3 is Figure 2 , a partial enlarged view of B in FIG. 1. The present embodiment provides a roller dismounting device applied in a mechanical equipment including a roller, such as a coating machine, a roller press and the like related to battery pole piece production, as long as the mechanical equipment has a roller, the roller dismounting device can be applied to dismount the roller, which is not uniquely limited by the present embodiment. The roller dismounting device of the present embodiment includes a dismounting vehicle 1, a fixing assembly 2, two mounting plates 3 and two inner guide rods 4, the two mounting plates 3 are oppositely and coaxially arranged in the mechanical equipment, a working space of the roller is formed between the two mounting plates 3 (i.e. the roller works in this space when the mechanical equipment is running), a through hole 31 is formed on each mounting plate 3, the through holes 31 of the two mounting plates 3 are opposite to each other, each inner guide rod 4 is located between the two mounting plates 3 and the two ends of each inner guide rod 4 are arranged on the two mounting plates 3 respectively, the two inner guide rods 4 are opposite and spaced apart in the horizontal direction, and one end of each inner guide rod 4 penetrates the target mounting plate through the target through hole of the target mounting plate; the fixing assembly 2 is used for fixing the roller, the fixing assembly 2 has a sliding structure 21, the fixing assembly 2 is arranged in the working space and is in sliding cooperation with the two inner guide rods 4 through the sliding structure 21, and the two ends of the fixing assembly 2 are located in the through holes 31 of the two mounting plates 3 respectively; the dismounting vehicle 1 has a dismounting platform 11, and the dismounting platform 11 is provided with two outer guide rods 12 which are opposite and spaced apart, and one end of each outer guide rod 12 extends out of the dismounting platform 11. It should be noted that the target mounting plate refers to one of the two mounting plates 3, which is actually the mounting plate 3 located on the outside of the mechanical equipment.

[0031] Specifically, during the disassembly of the roller, one end of each of the two outer guide rods 12 extends from the disassembly platform 11 to connect with one end of each of the two inner guide rods 4 that penetrate the target mounting plate; the fixing assembly 2, guided by the two inner guide rods 4 and the two outer guide rods 12, slides out of the working space through the target through hole via the sliding structure 21, and then slides onto the disassembly platform 11, i.e., from... Figure 2 The fixed component 2 is slid from position P1 to P2. In this embodiment, the fixed component 2 is not limited to sliding engagement with the two inner guide rods 4 via the sliding structure 21, but can also slide engagement with the two outer guide rods 12 via the sliding structure 21. When the fixed component 2 is in the working space, it is supported by the two inner guide rods 4, and at this time, the fixed component 2 slides engagement with the two inner guide rods 4 via the sliding structure 21. After the fixed component 2 is slid out of the working space from the target through hole, it is supported by the two outer guide rods 12, and at this time, the fixed component 2 slides engagement with the two outer guide rods 12 via the sliding structure 21. Only in this way can the fixed component 2 slide between the working space and the disassembly platform 11. Preferably, the end of the outer guide rod 12 extending out of the disassembly and assembly platform 11 is provided with a connecting structure 13. The two connecting structures 13 are used to connect the two outer guide rods 12 to the two inner guide rods 4 respectively during the disassembly and assembly of the roller. It can be understood that in this embodiment, the connection between the outer guide rod 12 and the inner guide rod 4 is realized through the connecting structure 13 during the disassembly and assembly of the roller. This can effectively ensure the stability of the connection between the outer guide rod 12 and the inner guide rod 4, that is, ensure the stability of the sliding of the fixed component 2 between the working space and the disassembly and assembly platform 11.

[0032] That is, in the actual maintenance process of the roller, the roller needs to be first disassembled from the mechanical equipment for maintenance, and then assembled to the mechanical equipment after the maintenance of the roller is completed, and the disassembly and assembly process of the roller is that the worker pushes the disassembly and assembly vehicle 1 to the mechanical equipment, and connects the two outer guide rods 12 at one end of the disassembly and assembly platform 11 with the two inner guide rods 4 at one end of the target mounting plate respectively; based on the sliding cooperation between the sliding structure 21, the two inner guide rods 4 and the two outer guide rods 12, the worker first slides the fixing assembly 2 out of the target through hole on the target mounting plate from the working space, and then slides the fixing assembly 2 that has been slid out of the working space onto the disassembly and assembly platform 11, thereby completing the disassembly of the roller; the roller in the fixing assembly 2 is maintained on the disassembly and assembly platform 11; after the maintenance of the roller is completed, the worker slides the fixing assembly 2 on the disassembly and assembly platform 11 into the working space from the target through hole on the target mounting plate based on the sliding cooperation between the sliding structure 21, the two inner guide rods 4 and the two outer guide rods 12, and disconnects the two outer guide rods 12 and the two inner guide rods 4, thereby completing the assembly of the roller. In addition, it should be noted that the maintenance of the roller is not limited to being carried out on the disassembly and assembly platform 11, and in other embodiments, the connection between the two outer guide rods 12 and the two inner guide rods 4 can be first disconnected, and then the fixing assembly 2 is transported to the designated place for maintenance by using the disassembly and assembly vehicle 1. In this case, after the maintenance of the roller is completed, the fixing assembly 2 needs to be sent back to the mechanical equipment by using the disassembly and assembly vehicle 1, and then the connection between the two outer guide rods 12 and the two inner guide rods 4 is established, so as to facilitate the subsequent assembly of the fixing assembly 2 to the mechanical equipment.

[0033] It can be found from the above that in the disassembly and assembly process of the roller, the fixing assembly 2 fixed with the roller is supported by the two inner guide rods 4, the two outer guide rods 12 and the disassembly and assembly vehicle 1 (without the participation of the worker), and the worker only needs to perform the action of sliding the fixing assembly 2 out of / in the working space, which not only simplifies the disassembly and assembly process of the roller, but also reduces the labor intensity of the worker during the disassembly and assembly of the roller, finally improves the disassembly and assembly efficiency of the roller, shortens the downtime of the mechanical equipment during the maintenance of the roller, and ensures the continuity of production.

[0034] In some embodiments, please refer to Figure 4 and Figure 5 , Figure 4 is a structural schematic view of the fixing assembly, Figure 5 is Figure 4A local enlarged view of the middle C. The fixing assembly 2 comprises, in addition to the sliding structure 21, two bearing plates 22, two fixing structures 23 and a plurality of connecting rods 24. The two bearing plates 22 are arranged opposite and coaxially. Each connecting rod 24 is located between the two bearing plates 22 and has two ends arranged on the two bearing plates 22 respectively. The plurality of connecting rods 24 are distributed around the axis of the bearing plates 22. The two fixing structures 23 are arranged on the inner sides of the two bearing plates 22 respectively. The two fixing structures 23 are on the axis of the bearing plates 22 (i.e. the two fixing structures 23 are arranged opposite). The two fixing structures 23 are used for fixing the opposite ends of the roller respectively. Preferably, the connecting rods 24 are four. The four connecting rods 24 are distributed at the four corners of the bearing plates 22. The four connecting rods 24 and the two bearing plates 22 constitute a frame so as to provide support for the structures in the fixing assembly 2.

[0035] Further, the sliding structure 21 comprises four rotating wheels 211. Two rotating wheels 211 are arranged rotatably on each bearing plate 22. The two rotating wheels 211 on each bearing plate 22 are arranged opposite and spaced apart in the horizontal direction. When the fixing assembly 2 is located in the working space, the two bearing plates 22 are located in the through holes 31 of the two mounting plates 3 respectively. The two rotating wheels 211 on each bearing plate 22 abut and slide with the two inner guide rods 4 respectively. Preferably, the fixing assembly 2 further comprises a handle 25 arranged on the outer side of a bearing plate 22. When the fixing assembly 2 is located in the working space, the bearing plate 22 provided with the handle 25 is located in the target through hole on the target mounting plate. Thus, the worker can slide the fixing assembly 2 out of / in the working space through the handle 25.

[0036] As one or more of the embodiments, the fixing structure 23 comprises a base 231, a fixing seat 232, two sliders 233 and two guide rails 234, the two guide rails 234 are arranged on the inner side of the bearing plate 22, the two guide rails 234 are opposite and spaced apart in the horizontal direction, the two guide rails 234 extend in the vertical direction, the two sliders 233 are arranged on the two guide rails 234 respectively and are in sliding cooperation with the two guide rails 234 respectively, the base 231 is arranged on the two sliders 233, the fixing seat 232 is arranged on the base 231, the fixing seat 232 is used for fixing the end of the roller, and the two sliders 233 are used for sliding in the vertical direction along the two guide rails 234 respectively to drive the base 231, the fixing seat 232 and the roller to rise and fall synchronously. It can be understood that some rollers need to rise and fall in the vertical direction during work, such as rollers coated with glue and used for traction during production of battery pole pieces, and therefore the fixing structure 23 of the application is not only used for fixing the roller, but also used for realizing the rise and fall of the roller in the vertical direction, and in the fixing structure 23, since the sliders 233, the base 231 and the fixing seat 232 have a sequentially connected relationship, when the two sliders 233 slide in the vertical direction along the two guide rails 234 respectively, the base 231, the fixing seat 232 and the roller fixed by the fixing seat 232 will rise and fall in the vertical direction together. Preferably, the fixing seat 232 adopts a split type fixing seat, and the split type fixing seat can facilitate the disassembly and assembly of the roller relative to the fixing assembly.

[0037] In the one or more embodiments, please combine Figure 6 , Figure 6 is a distribution diagram of the lifting cylinder and the limiting assembly on the mounting plate 3, the mounting plate 3 is provided with the lifting cylinder 5, the lifting cylinder 5 is located below the base 231 when the fixing assembly 2 is located in the working space, the piston rod of the lifting cylinder 5 abuts against the base 231, and the lifting cylinder 5 is used for driving the base 231 to slide in the vertical direction along the two guide rails 234 through the extension and retraction of the piston rod, so as to drive the fixing seat 232 and the roller to rise and fall synchronously. Preferably, the bottom of the base 231 is provided with a lower top block (not shown in the figure), and the end of the piston rod is provided with an upper top block 6, the upper top block 6 abuts against the lower top block when the fixing assembly 2 is located in the working space; that is, when the lifting cylinder 5 drives the base 231 to rise and fall through the piston rod, the piston rod does not abut against the base 231 directly, but abuts against the lower top block on the base 231 through the upper top block 6, so that not only the stability of the lifting cylinder 5 driving the base 231 to rise and fall through the piston rod can be guaranteed, but also the damage risk of the piston rod can be effectively reduced.

[0038] In the one or more embodiments, the base 231 is formed with a limiting protrusion (not shown in the figure) between the two sliding blocks 233 on one side close to the bearing plate 22, and the bearing plate 22 is provided with a limiting block (not shown in the figure) between the two guide rails 234 on the inner side, the limiting protrusion is used to abut against the limiting block when the base 231 is lowered into position along the two guide rails 234. That is, in actual application, when the lifting cylinder 5 drives the base 231 to descend, after the base 231 is lowered to a certain height, the limiting protrusion on the base 231 will abut against the limiting block on the bearing plate 22, and the limiting block will block the limiting protrusion from moving downward, that is, block the base 231 from continuing to descend, so as to effectively prevent the two sliding blocks 233 from disengaging from the guide rails 234 together with the base 231 and the like when the base 231 is lowered along the two guide rails 234.

[0039] As one or more embodiments thereof, the mounting plate 3 is provided with a limiting assembly 7, which is located above the base 231 when the fixing assembly 2 is located in the working space, and the limiting assembly 7 is used to limit the upper limit of the base 231 when it is raised along the two guide rails 234. That is, in the process of the base 231 being raised by the lifting cylinder 5, when the base 231 is raised to a certain height, it will abut against the limiting assembly 7, and the limiting assembly 7 will block the base 231 from continuing to rise, so as to effectively prevent the two sliding blocks 233 from disengaging from the guide rails 234 together with the base 231 and the like when the base 231 is raised along the two guide rails 234.

[0040] In the one or more embodiments, please combine Figure 7 and Figure 8 , Figure 7 is Figure 1 a partial enlarged view of A in Figure 8 is Figure 6The local enlarged view at the middle D shows that the limiting assembly 7 comprises a hand wheel 71, a rotating seat 72, a lead screw 73, a screw block 74, an extension rod 75 and a wedge block 76. The rotating seat 72 is arranged on the mounting plate 3. The lead screw 73 penetrates through the rotating seat 72 and is rotationally connected with the rotating seat 72. The hand wheel 71 is arranged on one end of the lead screw 73. The screw block 74 is sleeved on the lead screw 73 and is close to the other end of the lead screw 73. The screw block 74 is threadedly connected with the lead screw 73. One end of the extension rod 75 is arranged on the side of the screw block 74 away from the rotating seat 72. The wedge block 76 is arranged on the other end of the extension rod 75. When the fixing assembly 2 is located in the working space, the wedge block 76 is located above the base 231. Specifically, the hand wheel 71 is used to drive the lead screw 73 to rotate under the action of an external force (from a worker) and to drive the screw block 74, the extension rod 75 and the wedge block 76 to move synchronously in the horizontal direction along the lead screw 73, so as to adjust the upper limit position of the base 231 when the base 231 rises along the two guide rails 234. That is to say, in actual application, the limiting assembly 7 is not only used to limit the upper limit position of the base 231 when the base 231 rises along the two guide rails 234, but also can adjust the upper limit position. In the limiting assembly 7, since the wedge block 76 has an inclined surface and the inclined surface faces the base 231, when the wedge block 76 moves in the horizontal direction, the distance between the wedge block 76 and the base 231 changes, and the upper limit position of the base 231 when the base 231 rises along the two guide rails 234 also changes, so that the adjustment of the upper limit position is realized.

[0041] In the one or more embodiments, the limiting assembly 7 further comprises a guide block 77 arranged on the mounting plate 3 and located above the wedge block 76. The wedge block 76 abuts against the guide block 77. The guide block 77 is used to abut against the screw block 74 in the process that the screw block 74 moves along the lead screw 73 away from the rotating seat 72. It can be understood that the guide block 77 is arranged above the wedge block 76 and abuts against the wedge block 76, so as to limit the degree of freedom of the wedge block 76 through the guide block 77, and the wedge block 76 can only move in the horizontal direction. In addition, in the process that the screw block 74 moves along the lead screw 73 away from the rotating seat 72, when the screw block 74 moves to a certain position, the screw block 74 abuts against the guide block 77, and the guide block 77 blocks the screw block 74 from continuing to move away from the rotating seat 72, so that the screw block 74 can be effectively prevented from moving away from the rotating seat 72.
