Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] like Figures 1 to 5 As shown, it is a disassembly device of an embodiment of the present invention, which is used for automatically disassembling a cross-flow fan 70. The cross-flow fan 70 generally includes two end covers, an impeller connecting the two end covers, and metal parts (such as a rotating shaft) arranged on the two end covers. Disassembling the cross-flow fan 70 is to separate the metal parts from the end covers.

[0029] See also Figure 1-Figure 5 The disassembling device of the embodiment of the present invention includes a workbench 10 and a disassembling module 20. The disassembling module 20 includes a fixing component 21 and a disassembling component 22. The fixing component 21 is arranged on the workbench 10, and is used to fix the crossflow fan 70. The disassembling component 22 includes an annular cutter 221, a rotating mechanism 222 and a translation mechanism 223. The rotating mechanism 222 is connected to the annular cutter 221 and is used to drive the annular cutter 221 to rotate. The translation mechanism 223 is arranged on the workbench 10, and the translation mechanism 223 is connected to the rotating mechanism 222, and is used to drive the rotating mechanism 222 to drive the annular cutter 221 to move back and forth (that is, including the movement of the end cover close to the crossflow fan 70 and the movement of the end cover away from the crossflow fan 70). The annular cutter 221 cuts the end cover of the crossflow fan 70 under the synchronous action of the translation mechanism 223 and the rotating mechanism 222 to separate the metal parts of the crossflow fan 70 from the end cover.

[0030] The disassembly device of the embodiment of the present invention includes a disassembly module 20, which fixes the crossflow fan 70 through the fixing component 21 when disassembling the crossflow fan 70, and then drives the annular cutter 221 to rotate through the rotating mechanism 222 of the disassembly component 22, and at the same time drives the annular cutter 221 to move toward the end cover of the crossflow fan 70 through the translation mechanism 223 until the annular cutter 221 completes the end cover cutting operation, and then drives the annular cutter 221 to reset through the translation mechanism 223, and the rotating mechanism 222 stops working, and the fixing component 21 releases the crossflow fan 70, and the disassembly of the metal parts and the end cover of the crossflow fan 70 is completed. During disassembly, it only needs to place the crossflow fan 70 to be disassembled on the fixing component 21 to realize the automatic disassembly of the crossflow fan 70. After the disassembly is completed, the disassembled crossflow fan 70 is taken out manually and by a robot, and the disassembly efficiency is high. Moreover, the cross-flow blower 70 is automatically disassembled by the disassembling device, and the disassembly is precise. The disassembled impeller and the end cover part connected to the impeller can be recycled, which is beneficial to improving the recovery rate of materials.

[0031] See also Figure 1-Figure 4 , exemplarily, in some embodiments, the fixing assembly 21 includes a first fixing block 211 disposed on the workbench 10, a second fixing block 212 cooperating with the first fixing block 211, and a first driving member 213 disposed on the workbench 10, the first fixing block 211 and the second fixing block 212 are both provided with a positioning groove 2113 for matching with the impeller of the cross-flow fan 70, the first driving member 213 is connected to the second fixing block 212, and is used to drive the second fixing block 212 to move close to the first fixing block 211 to clamp the impeller of the cross-flow fan 70 or drive the second fixing block 212 to move away from the first fixing block 211 to loosen the impeller of the cross-flow fan 70, and the fixing method is simple and reliable.

[0032] Optionally, the first driving member 213 is a cylinder, which has the advantages of convenient control and low cost.

[0033] It can be understood that the first fixing block 211 and the second fixing block 212 can clamp the cross flow fan 70 from the up and down direction or from the left and right direction, which is specifically determined according to the installation position of the fixing assembly 21 .

[0034] See also Figure 1-Figure 4 For example, in some embodiments, the first fixed block 211 is detachably mounted on the workbench 10, the second fixed block 212 is detachably connected to the first driving member 213, the first fixed block 211 and the second fixed block 212 are detachably mounted, and different products can be installed with fixed blocks of different specifications, which can expand the scope of application of the disassembly device.

[0035] Optionally, the fixing assembly 21 further includes a first clamping block 214, a second clamping block 215, a first tightening screw 216 and a second tightening screw 217. The first clamping block 214, the second clamping block 215, the first tightening screw 216 and the second tightening screw 217 are each provided with two, the first fixing block 211 is provided in an inverted T shape, the first fixing block 211 includes a first bottom plate 2111 and a first vertical plate 2112 provided on the first bottom plate 2111, the first vertical plate 2112 is provided with a positioning groove 2113, the two first clamping blocks 214 press the first bottom plate 2111 on the workbench 10, the two first clamping blocks 214 are respectively located on both sides of the first vertical plate 2112, and a first tightening screw 21 6 is threadedly connected to a first clamping block 214 and is used to tighten the first bottom plate 2111 to prevent the first bottom plate 2111 from moving. The second fixing block 212 is arranged in an inverted T shape. The second fixing block 212 includes a second bottom plate 2121 and a second vertical plate 2122 arranged on the second bottom plate 2121. The second vertical plate 2122 is provided with a positioning groove 2113. Two second clamping blocks 215 press the second bottom plate 2121 onto the first driving member 213. The two second clamping blocks 215 are respectively located on both sides of the second vertical plate 2122. A second tightening screw 217 is threadedly connected to a second clamping block 215 and is used to tighten the second bottom plate 2121 to prevent the second bottom plate 2121 from moving. When the first fixing block 211 needs to be replaced, the first tightening screw 216 is loosened, and then the first fixing block 211 is slid out, replaced with a new first fixing block 211, and the new first fixing block 211 is slid between the first clamping block 214 and the workbench 10, and the first tightening screw 216 is tightened to complete the replacement of the first fixing block 211. Similarly, when the second fixing block 212 needs to be replaced, the second tightening screw 217 is loosened, and then the second fixing block 212 is slid out, replaced with a new second fixing block 212, and the new second fixing block 212 is slid between the second clamping block 215 and the workbench 10, and the second tightening screw 217 is tightened to complete the replacement of the second fixing block 212, which is convenient for loading and unloading.

[0036] Specifically, the first pressing block 214 is screwed to the workbench 10 , and the second pressing block 215 is screwed to the first driving member 213 .

[0037] It is understandable that the first fixing block 211 and the workbench 10 may also be connected in other ways, for example, the two are connected by a buckle. Similarly, the second fixing block 212 and the first driving member 213 may also be connected in other ways, for example, the two are connected by a buckle.

[0038] Optionally, the positioning groove 2113 is a through groove, and the first fixed block 211 also includes a limit plate 2114 arranged on the vertical plate. When the cross-flow fan 70 is placed, an initial positioning is given to the cross-flow fan 70 so that the travel distance of the annular tool 221 can be preset in advance. In this way, it is only necessary to start the disassembly device at the beginning of disassembly, and the disassembly device can complete the automatic disassembly of the cross-flow fan 70 to be disassembled, and there is no need to judge when the disassembly device completes the cutting operation of the end cover and reset the disassembly device.

[0039] It is understandable that the positioning groove 2113 can also be configured as a blind groove, which can also provide an initial positioning for the cross-flow blower 70 .

[0040] See also Figure 1-Figure 4 , exemplarily, in some embodiments, the fixing assembly 21 also includes a bracket 218 and a mounting seat 219, the bracket 218 is arranged on the workbench 10, the bracket 218 is provided with a slide rail 2181, the mounting seat 219 is provided with a slider 2191 that cooperates with the slide rail 2181, the first driving member 213 is installed on the bracket 218, and the output end of the first driving member 213 is connected to the second fixed block 212 through the mounting seat 219. When the first driving member 213 drives the second fixed block 212 to move, the slider 2191 slides along the slide rail 2181, so that the second fixed block 212 slides more smoothly.

[0041] See also Figure 1-Figure 5 , exemplarily, in some embodiments, the annular tool 221 includes a tool seat 2211, a tool shaft 2212 and an annular tool body 2213, the tool shaft 2212 and the annular tool body 2213 are respectively arranged on both sides of the tool seat 2211, and the rotating mechanism 222 is connected to the tool shaft 2212.

[0042] See also Figure 1-Figure 5 , exemplarily, in some embodiments, the disassembly component 22 also includes a coupling 224, the rotating mechanism 222 includes an installation box 2221, a belt transmission mechanism 2222 and a second driving member 2223, the belt transmission mechanism 2222 is arranged in the installation box 2221, and the second driving member 2223 is supported on the outside of the installation box 2221, the coupling 224 is connected to one end of the installation box 2221, and the output end of the translation mechanism 223 is connected to the other end of the installation box 2221, the first rotating end of the coupling 224 is connected to the annular tool 221, and the second rotating end of the coupling 224 is connected to the second driving member 2223 through the belt transmission mechanism 2222. With this design, the translation mechanism 223 and the annular tool 221 can be arranged on the same straight line, and the second driving member 2223 can be arranged above or on the side of the translation mechanism 223, thereby improving the compactness of the disassembly component 22 and reducing its occupied space.

[0043] Optionally, the belt drive mechanism 2222 includes a driving wheel, a transmission wheel and a transmission belt. The driving wheel is sleeved on the output end of the second driving member 2223, and the driven wheel is sleeved on the second rotating end of the coupling 224. The transmission belt is wrapped around the driving wheel and the driven wheel, and the transmission method is simple and reliable.

[0044] Optionally, the second driving member 2223 is a motor, which has the advantages of small size and light weight.

[0045] Optionally, the translation mechanism 223 is driven by a cylinder, which has the advantages of convenient control and low cost.

[0046] It can be understood that the disassembly assembly 22 can also be provided with a sliding structure between the coupling 224 and the workbench 10, and the coupling 224 is supported by the sliding structure. When the translation mechanism 223 drives the annular cutter 221 to move, the coupling 224 slides relative to the workbench 10.

[0047] See also Figure 1-Figure 5 For example, in some embodiments, two fixing components 21 and two disassembling components 22 are respectively provided, and one fixing component 21 and one disassembling component 22 constitute a disassembling module 20, and the disassembling component 22 is located on the outside of the fixing component 21, and the two disassembling modules 20 are respectively arranged on both sides of the workbench 10. By setting two disassembling modules 20, both ends of the cross-flow blower 70 can be disassembled at the same time, and the disassembly effect is higher.

[0048] When only one fixing assembly 21 and only one disassembling assembly 22 are provided, one end of the cross flow blower 70 may be disassembled first, and then the other end of the cross flow blower 70 may be disassembled.

[0049] See also Figure 1-Figure 5 For example, in some embodiments, the disassembly module 20 also includes a base plate 23 slidably disposed on the workbench 10, and the fixing component 21 and the disassembly component 22 are disposed on the workbench 10 through the base plate 23, so that the distance between the two disassembly modules 20 is adjustable, so that the disassembly device can be suitable for cross-flow blowers 70 of different lengths.

[0050] Optionally, the disassembly device also includes a guide rail 40, a guide rail seat 50 and a screw nut mechanism 30. The guide rail seat 50 is slidably matched with the guide rail 40. The two disassembly modules 20 are both provided with a guide rail seat 50. Two screw nut mechanisms 30 are provided. The two screw nut mechanisms 30 are arranged in a one-to-one correspondence with the two disassembly modules 20. Each screw nut mechanism 30 includes a screw rod 31 and a nut 32 that are threadedly matched. The screw rod 31 is rotatably arranged on the workbench 10, and the nut 32 is arranged on the base plate 23 to drive the base plate 23 to slide. The position of the disassembly module 20 can be adjusted by rotating the screw rod 31. The sliding method is simple and reliable, and the cooperation between the guide rail seat 50 and the guide rail 40 makes the disassembly module 20 slide more smoothly, and can also support the disassembly module 20, that is, the disassembly module 20 can be supported by the guide rail 40 and the screw nut mechanism 30 at the same time, rather than being supported only by the screw nut mechanism 30.

[0051] Furthermore, the screw-nut mechanism 30 further includes a handle 33 disposed at one end of the screw rod 31 , and the screw rod 31 can be driven to rotate by rotating the handle 33 , making the operation more convenient.

[0052] It is understandable that, in addition to providing the handle 33 to drive the screw rod 31 to rotate, a motor may also be provided to drive the screw rod 31 to rotate.

[0053] It can be understood that in addition to the screw-nut mechanism 30, the disassembling device can also drive the base plate 23 slide by arranging a driving cylinder or other linear driving device.

[0054] Furthermore, two guide rails 40 are provided, and the two guide rails 40 are arranged on the workbench 10 at an interval and in parallel, and the screw nut mechanism 30 is arranged between the two guide rails 40 .

[0055] See also Figure 1-Figure 3 For example, in some embodiments, the disassembly device also includes a controller 60 disposed on the workbench 10, and the controller 60 is respectively connected to the fixed component 21, the rotating mechanism 222 and the translation mechanism 223, and is used to control the operation of the fixed component 21, the rotating mechanism 222 and the translation mechanism 223.

[0056] See also Figure 1-Figure 3, exemplarily, in some embodiments, the disassembly module 20 also includes a limit mechanism 24, the limit mechanism 24 includes a travel switch 241 and a stopper 242 cooperating with the travel switch 241, the travel switch 241 is connected to the controller 60, the travel switch 241 is arranged on the workbench 10, the stopper 242 is arranged on the disassembly component 22, the stopper 242 moves with the annular tool 221, when the stopper 242 touches the travel switch 241, the travel switch 241 feeds back a signal to the controller 60, and the controller 60 controls the translation mechanism 223 to stop moving toward the cross flow blower 70 and reset. With this design, there is no need to pre-input the moving stroke of the translation mechanism 223, and the control is more convenient.

[0057] It can be understood that the travel switch 241 and the stopper 242 only need to be fixed relative to the disassembly component, and the other one can move with the disassembly component, and the specific settings can be adjusted according to actual conditions. For example, when the disassembly module 20 can slide through the base plate 23, the travel switch 241 is set on the base plate 23, and the stopper 242 can be set on the coupling 224 of the disassembly module 20.

[0058] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention.
