[0038] Figure 1 FIG. is a schematic diagram of a battery nail-pulling device 100 provided according to one embodiment of the present application. Figure 2 is Figure 1 a schematic diagram of the battery nail-pulling device 100 in FIG. from another perspective. Figure 3 is Figure 1 a sectional view of the battery nail-pulling device 100 in FIG. at A-A.

[0039] It should be noted that in the present application, the "X direction", "Y direction", and "Z direction" mentioned are based on the rectangular coordinate system constructed by the battery nail-pulling device 100. Among them, the X direction is also the longitudinal direction, the Y direction is also the transverse direction, the Z direction is also the vertical direction, the up and down direction, the lifting direction, and the height direction.

[0040] Please refer to Figures 1 to 3 , the battery nail-pulling device 100 includes a frame 10, a station switching device 20, and a nail-pulling and inspection module 30. The station switching device 20 is disposed on the frame 10 in the Z direction.

[0041] The nail-pulling and inspection module 30 is slidably connected to the frame 10 and is driven by the station switching device 20 to move in the X direction to switch between the nail-pulling and inspection position and the nail-unloading position. Among them, the nail-pulling and inspection module 30 is used for clamping and inspecting nails at the nail-pulling and inspection position, and unloading nails at the nail-unloading position.

[0042] In this embodiment, the battery nail-pulling device 100 at least includes a frame 10, a station switching device 20, and a nail-pulling and inspection module 30. Among them, the frame 10 provides support for other components in the battery nail-pulling device 100. It should be noted that the frame 10 is a frame structure that can be assembled by multiple beam members, and a passage for the battery carrier 200 to pass through is formed inside the frame 10.

[0043] The station switching device 20 is fixedly installed on the top side of the rack 10 in the Z direction. The nail extraction and inspection module 30 is slidably connected to the rack 10 and is drivingly connected to the station switching device 20 to move relative to the rack 10 in the X direction under the drive of the station switching device 20. That is, the nail extraction and inspection module 30 is switched between the nail extraction and inspection position and the nail unloading position.

[0044] When in the nail extraction and inspection position, the nail extraction and inspection module 30 can first perform a nail inspection operation on the battery in the battery carrier 200 in the rack 10, and then perform a nail clamping operation when it is confirmed that there is a nail. When in the nail unloading position, the nail extraction and inspection module 30 performs a nail unloading operation. It can be understood that after the nail clamping is completed in the nail extraction and inspection position, during the process of switching to the nail unloading position, the nail 201 in the battery is pulled out.

[0045] It can be seen that in this application, the nail inspection function module and the nail extraction function module are integrated into one to form the nail extraction and inspection module 30, and the nail extraction and inspection operations are realized on one side in the X direction of the battery carrier 200. The integration degree of the entire battery nail extraction device 100 is higher and the cost is relatively reduced.

[0046] It should be noted here that most of the existing battery nail extraction devices perform nail extraction operations in the X direction, while the battery nail extraction device 100 provided in this application adopts a scheme of realizing nail extraction and inspection operations on the X side, which is more conducive to performing nail extraction and inspection operations on blade batteries.

[0047] In a further optional embodiment, the nail extraction and inspection module 30 includes a nail extraction module 31, a nail inspection module 32, and a movable crossbeam frame 33.

[0048] Both the nail extraction module 31 and the nail inspection module 32 are connected to the movable crossbeam frame 33 and are located below the station switching device 20 in the Z direction. The movable crossbeam frame 33 is slidably connected to the rack 10 and is driven by the station switching device 20 to drive the nail extraction module 31 and the nail inspection module 32 to move together in the X direction.

[0049] The nail extraction module 31 is used for clamping nails in the nail extraction and inspection position and unloading nails in the nail unloading position, and the nail inspection module 32 is used for inspecting nails in the nail extraction and inspection position.

[0050] In this embodiment, the nail extraction and inspection module 30 at least includes a nail extraction module 31, a nail inspection module 32, and a movable crossbeam frame 33. Both the nail extraction module 31 and the nail inspection module 32 are connected to the movable crossbeam frame 33 and are slidably connected to the rack 10 through the movable crossbeam frame 33.

[0051] In other words, the movable crossbeam frame 33 has a moving degree of freedom in the X direction. In this way, the nail extraction module 31 and the nail inspection module 32 can have a moving degree of freedom in the X direction along with the movable crossbeam frame 33.

[0052] Specifically, driven by the station switching device 20, the movable crossbeam frame 33 can drive the nail pulling module 31 and the nail inspection module 32 to linearly move along the X direction together, so as to realize the switching between the nail pulling and inspection position and the nail unloading position.

[0053] In a specific application, the station switching device 20 is a cylinder, and first guide rails 101 are provided at both ends in the Y direction on the top side of the frame 10 to cooperate with the movable crossbeam frame 33 to realize a sliding connection. In other words, the function of station switching is realized by the cooperation of the cylinder and the guide rail transmission mechanism. Of course, it is not limited to this. For example, the station switching device 20 can also be a motor to cooperate with transmission mechanisms such as a rack and pinion or a ball screw to realize station switching.

[0054] In an exemplary usage scenario, when the nail pulling and inspection module 30 is in the nail pulling and inspection position, the nail inspection module 32 detects whether there is a nail 201 on the battery in the battery carrier 200. If so, the nail pulling module 31 is allowed to perform a nail clamping operation.

[0055] After the nail clamping operation is completed, during the process of the nail pulling and inspection module 30 moving to the nail unloading position driven by the station switching device 20, the clamped nail 201 is pulled out by the nail pulling module 31.

[0056] Next, when the nail pulling and inspection module 30 is in the nail unloading position, the nail pulling module 31 can unload the pulled-out nail, that is, perform a nail unloading operation.

[0057] In a further optional embodiment, the nail pulling module 31 includes an upper clamping plate structure 311, a lower clamping plate structure 312, a first driving component 313, and a support frame 314.

[0058] The support frame 314 is connected to the movable crossbeam frame 33, and both the upper clamping plate structure 311 and the lower clamping plate structure 312 are slidably connected to the support frame 314.

[0059] The first driving component 313 is arranged on the support frame 314 and is used to drive the upper clamping plate structure 311 and the lower clamping plate structure 312 to move closer to or away from each other in the Z direction.

[0060] In this embodiment, the nail pulling module 31 at least includes an upper clamping plate structure 311, a lower clamping plate structure 312, a first driving component 313, and a support frame 314. The support frame 314 is fixedly installed on the movable crossbeam frame 33, and the upper clamping plate structure 311, the lower clamping plate structure 312, and the first driving component 313 are all installed on the support frame 314.

[0061] Among them, both the upper clamping plate structure 311 and the lower clamping plate structure 312 are slidably connected to the support frame 314 and are spaced apart in the Z direction, that is, spaced apart vertically. Specifically, both the upper clamping plate structure 311 and the lower clamping plate structure 312 have a Z-direction movement degree of freedom.

[0062] Further, the upper clamping plate structure 311 and the lower clamping plate structure 312 can linearly move in the Z direction, that is, move in the up and down direction, under the drive of the first drive assembly 313 to approach or move away from each other.

[0063] It should be understood that when the upper clamping plate structure 311 and the lower clamping plate structure 312 approach each other, the nail clamping operation is realized. When the upper clamping plate structure 311 and the lower clamping plate structure 312 move away from each other, the nail 201 is released, that is, the nail unloading operation is realized.

[0064] In a specific application, second guide rails 301 are provided on both sides of the support frame 314 in the Y direction to realize the sliding connection with the upper clamping plate structure 311 and the lower clamping plate structure 312. The first drive assembly 313 is two drive cylinders, which are respectively used to drive the upper clamping plate structure 311 and the lower clamping plate structure 312 to move in the Z direction. Of course, the first drive assembly 313 is not limited to the combination of two cylinders. For example, it can also be the combination of two linear motors.

[0065] Figure 4 For Figure 1 the partial enlarged view at S in. Please refer to Figure 4 In some alternative embodiments, the upper clamping plate structure 311 includes an upper clamping plate mounting plate 3111 and an upper clamping plate 3112, and the upper clamping plate mounting plate 3111 and the upper clamping plate 3112 are spliced in the X direction. The lower clamping plate structure 312 includes a lower clamping plate mounting plate 3121 and a lower clamping plate 3122, and the lower clamping plate mounting plate 3121 and the lower clamping plate 3122 are spliced in the X direction.

[0066] In this embodiment, both the upper clamping plate structure 311 and the lower clamping plate structure 312 adopt a similar structure, specifically the splicing structure of the clamping plate mounting plate and the clamping plate in the X direction. In a specific application, bumps are provided at the X-direction ends of the upper clamping plate 3112 and the lower clamping plate 3122 close to the battery carrier 200 to increase the clamping friction.

[0067] In a further alternative embodiment, the nail detection module 32 is arranged between the upper clamping plate structure 311 and the lower clamping plate structure 312 and includes a nail detection structure 321 and a second drive assembly 322.

[0068] The nail detection structure 321 is slidably connected to the support frame 314, and the second drive assembly 322 is arranged on the support frame 314 and is used to drive the nail detection structure 321 to move in the X direction at the nail pulling and detecting position.

[0069] In this embodiment, the nail inspection module 32 is located between the upper clamping plate structure 311 and the lower clamping plate structure 312, preferably at the middle position between the upper clamping plate structure 311 and the lower clamping plate structure 312. The upper clamping plate structure 311 and the lower clamping plate structure 312 move closer to the nail inspection module 32 in the middle under the drive of the first drive assembly 313. The height position corresponding to the nail inspection module 32 is the height of the nails 201 on the battery in the battery carrier 200.

[0070] The nail inspection module 32 at least includes a nail inspection structure 321 and a second drive assembly 322. The nail inspection structure 321 is slidably mounted on the support frame 314 and has a movable degree of freedom in the X direction. The second drive assembly 322 is used to drive the nail inspection structure 321 to move in the X direction to implement the nail inspection operation.

[0071] In this embodiment, the second drive assembly 322 is a cylinder fixedly installed on both sides in the Y direction of the support frame 314. The nail inspection structure 321 is driven to move in the X direction by synchronously driving the two cylinders. Of course, the second drive assembly 322 is not limited to the combination of two cylinders. For example, it can also be a combination of two linear motors.

[0072] In a further optional embodiment, the nail inspection structure 321 includes a mounting frame 3211, a plurality of nail inspection telescopic rods 3212, and a plurality of detection switches 3213.

[0073] The mounting frame 3211 is slidably connected to the support frame 314. A plurality of nail inspection telescopic rods 3212 and a plurality of detection switches 3213 are arranged at intervals in the Y direction on the mounting frame 3211 and correspondingly form a row of nail inspection telescopic rods L1 and a row of detection switches L2.

[0074] The row of nail inspection telescopic rods L1 and the row of detection switches L2 are arranged at intervals in the X direction, and each nail inspection telescopic rod 3212 in the row of nail inspection telescopic rods L1 is aligned with each detection switch 3213 in the row of detection switches L2 in the X direction.

[0075] Each nail inspection telescopic rod 3212 is arranged to be able to telescopically move in the X direction and move to the position where the corresponding detection switch 3213 is located.

[0076] In the embodiment, the nail inspection structure 321 at least includes a mounting frame 3211, a plurality of nail inspection telescopic rods 3212, and a plurality of detection switches 3213. Specifically, a plurality of nail inspection telescopic rods 3212 and a plurality of detection switches 3213 are both integrated on the mounting frame 3211, and are connected to the support frame 314 through the mounting frame 3211.

[0077] Further, a plurality of nail inspection telescopic rods 3212 and a plurality of detection switches 3213 are arranged at intervals along the Y direction to respectively form a row of nail inspection telescopic rods L1 and a row of detection switches L2. Moreover, the row of nail inspection telescopic rods L1 is located on the side closer to the battery carrier 200 than the row of detection switches L2.

[0078] Each nail inspection telescopic rod 3212 in the row of nail inspection telescopic rods L1 is arranged in alignment with each detection switch 3213 in the row of detection switches L2. Moreover, each nail inspection telescopic rod 3212 can telescopically move along the X direction to the position where the corresponding detection switch 3213 is located, so as to confirm whether there are still nails remaining in the battery in the battery carrier 200 through the switching signal emitted by the detection switch 3213.

[0079] It can be seen that the combination of the plurality of nail inspection telescopic rods 3212 and the plurality of detection switches 3213 forms a plurality of nail inspection points arranged at intervals in the Y direction.

[0080] It should be understood that the nails 201 on the battery protrude from the battery surface. When the nail inspection module 30 is in the nail inspection position, if there are still nails 201 at the battery surface position, the nail 201 will abut against the corresponding nail inspection telescopic rod 3212, so that the nail inspection telescopic rod 3212 retracts towards the corresponding detection switch 3213 until the detection switch 3213 is triggered to generate a switching signal, thereby enabling the nail pulling module 31 to perform the nail clamping operation again to avoid missing nails.

[0081] In a specific application, guide rods 302 are provided at both ends of the mounting bracket 3211 in the Y direction, and the sliding fit with the support frame 314 is realized through the guide rods 302. The detection switch 3213 is a groove type photoelectric switch, and of course, it is not limited thereto. For example, it can also be a micro switch, etc.

[0082] In some optional embodiments, the movable crossbeam frame 33 includes a crossbeam 331, a mounting plate 332, and a Z-direction position adjustment structure 333.

[0083] The crossbeam 331 is slidably connected to the machine frame 10, and the mounting plate 332 is connected to the crossbeam 331 and is located at both ends of the crossbeam 331 in the Y direction.

[0084] The Z-direction position adjustment structure 333 is arranged on the mounting plate 332 and is connected to the support frame 314 to adjust the position of the support frame 314 relative to the mounting plate 332 in the Z direction.

[0085] In this embodiment, the movable crossbeam frame 33 at least includes a crossbeam 331, a mounting plate 332, and a Z-direction position adjustment structure 333. The crossbeam 331 can be slidably connected to the machine frame 10 through the first guide rail 101, and mounting plates 332 and Z-direction position adjustment structures 333 are provided at both ends of the crossbeam 331 in the Y direction.

[0086] The two ends of the support frame 314 in the Y direction are connected to the mounting plates 332 at the two Y-direction ends through the Z-direction position adjusting structure 333 at the two Y-direction ends. Moreover, the Z-direction position of the support frame 314, that is, the height position, can be adjusted through the Z-direction position adjusting structure 333.

[0087] As can be seen from the foregoing, the other components in the nail-pulling and nail-inspecting module 30 are all arranged based on the support frame 314. Adjusting the height of the support frame 314 is equivalent to adjusting the height positions of the nail-pulling module 31 and the nail-inspecting module 32, so as to adapt to different specifications of batteries.

[0088] In the illustrated embodiment, the Z-direction position adjusting structure 333 is a stud connection structure. Specifically, the mounting plate 332 and the support frame 314 are connected by studs arranged in the Z direction. By rotating the studs, the relative movement of the support frame 314 in the Z direction with respect to the mounting plate 332 can be adjusted. Of course, the Z-direction position adjusting structure 333 is not limited to the stud connection structure, for example, it can also be a lead screw connection structure, etc.

[0089] In a further optional embodiment, the movable crossbeam frame 33 further includes a limit block 334. The limit block 334 is arranged at the two Y-direction ends of the crossbeam 331 and is located above the nail-pulling module 31.

[0090] The machine frame 10 is provided with a buffer joint 11 on the top side. In the state where the nail-pulling and nail-inspecting module 30 is in the nail-pulling and nail-inspecting position, the limit block 334 abuts against the buffer joint 11; in the state where the nail-pulling and nail-inspecting module 30 is in the nail-unloading position, the limit block 334 is away from the buffer joint 11.

[0091] In this embodiment, the position of the buffer joint 11 on the top side of the machine frame 10 is fixed, and the movable crossbeam frame 33 can move closer to or away from the buffer joint 11 under the drive of the station switching device 20. Among them, the position where the buffer joint 11 is located defines the nail-pulling and nail-inspecting position. During the process of the station switching device 20 driving the movable crossbeam frame 33 towards the buffer joint 11, when the limit block 334 in the movable crossbeam frame 33 abuts against the buffer joint 11, it indicates that the nail-pulling and nail-inspecting module 30 has reached the nail-pulling and nail-inspecting position.

[0092] Correspondingly, when the limit block 334 is away from the buffer joint 11, it indicates that the nail-pulling and nail-inspecting module 30 is in the nail-unloading position. In a specific application, the station switching device 20 is a cylinder, and when it retracts, the limit block 334 abuts against the buffer joint 11. When the station switching device 20 is at its maximum extended stroke, the nail-pulling and nail-inspecting module 30 is in the nail-unloading position.

[0093] In some optional embodiments, the battery nail-pulling device 100 further includes a nail-sweeping module 40. The nail-sweeping module 40 is arranged on the top side of the machine frame 10 in the Z direction. The nail-sweeping module 40 is used to sweep the nails of the nail-pulling and nail-inspecting module 30 in the nail-unloading position.

[0094] In this embodiment, a nail sweeping module 40 is fixedly installed on the top side of the rack 10. When the nail pulling and inspecting module 30 is in the nail unloading position, to avoid the situation that the nail does not fall in time during the nail unloading operation (loosening the nail 201), the nail sweeping module 40 sweeps off the nail 201 located on the nail pulling and inspecting module 30.

[0095] In a further optional embodiment, the nail sweeping module 40 includes a lifting driving device 41 and a nail sweeping plate 42. The nail sweeping plate 42 is connected to the lifting driving device 41 and partially overlaps the nail pulling and inspecting module 30 in the Z direction at the nail unloading position. The lifting driving device 41 is used to drive the nail sweeping plate 42 to sweep the nails on the nail pulling and inspecting module 30.

[0096] In this embodiment, the nail sweeping module 40 at least includes a lifting driving device 41 and a nail sweeping plate 42. The lifting driving device 41 is used to drive the nail sweeping plate 42 to lift and lower, that is, move in the Z direction. When the nail pulling and inspecting module 30 is in the nail unloading position, since the projection of the nail sweeping plate 42 in the Z direction partially overlaps the nail pulling and inspecting module 30, the nail sweeping plate 42 falls under the drive of the lifting driving device 41 and can contact the nail 201 that has not fallen in the nail pulling and inspecting module 30, so as to realize brushing off the nails 201 that have not fallen.

[0097] In specific applications, the partial projection of the nail sweeping plate 42 in the Z direction overlaps the upper clamping plate 3112 and the lower clamping plate 3122 in the nail pulling and inspecting module 30. The nail sweeping plate 42 is made of materials such as elastic plastic and elastic silica gel to avoid rigid collision with the clamping plate and ensure that the nail 201 can be swept off. The lifting driving device 41 can be a cylinder. Of course, the lifting driving device 41 can also be a linear motor, an oil cylinder, etc.

[0098] In some optional embodiments, the battery nail pulling device 100 further includes a funnel 50 and a material box 60. The funnel 50 is located below the nail pulling and inspecting module 30 in the Z direction at the nail unloading position, and the material box 60 is communicated with the funnel 50.

[0099] In this embodiment, after the nail pulling and inspecting module 30 unloads the nails at the nail unloading position, the nails 201 fall into the funnel 50 and enter the material box 60 to be collected, so as to realize the recycling of the nails 201. It should be noted that the nails 201 here are glue nails.

[0100] In summary, in the battery nail pulling device 100 provided by the present application, the nail pulling module 31 and the nail inspection module 32 are integrated to form a nail pulling and inspection module 30, so as to realize the functions of nail pulling and nail inspection, and avoid the situation of missed nail pulling. Moreover, the nail pulling and inspection module 30 is located on the X - side of the battery carrier 200, so as to realize the nail pulling and inspection operation on the X - side, which is more conducive to the nail pulling and inspection operation of the blade battery. Furthermore, the battery nail pulling device 100 is also integrated with a nail sweeping module 40 to avoid the situation that nails 201 still remain on the nail pulling and inspection module 30. Further, the height position of the nail pulling and inspection module 30 is adjustable, which can adapt to more specifications of batteries.

[0101] Although the embodiments of the present application have been shown and described above, it can be understood that the above - mentioned embodiments are exemplary and should not be construed as limiting the present application. Those skilled in the art can make changes, modifications, substitutions, and variations to the above - mentioned embodiments within the scope of the present application.
