Description

Technical Field

[0001] The utility model relates to the technical field of battery pack disassembly, in particular to a pulling claw mechanism. Background Art

[0002] When the battery pack is inspected or recycled, a disassembly device is usually used to automatically disassemble the outer shell of the battery pack. Chinese utility model patent CN219542213U discloses a battery shell disassembly device, including a driving part and two force-applying parts (clip plates), the driving mechanism has two output ends (screw sleeves), and the two force-applying parts are fixedly connected to different output ends. The outer shell is formed by two shells that are snapped together, and the two shells have force-applying areas that are relative in the disassembly direction. When working, the force-applying part corresponds to the force-applying area one by one, and the force-applying part moves in the opposite direction of the disassembly direction under the drive of the output end, thereby pushing the force-applying area to achieve the back separation of the shell.

[0003] Since there are many types of battery packs and their sizes vary greatly, the positions of the force-applying areas are different, so the position of the force-applying part on the drive mechanism needs to be adjusted accordingly so that it accurately corresponds to the force-applying area. However, the existing force-applying part is fixed to the output end by a connecting rod, and the relative position of the force-applying part and the connecting rod is not adjustable. When the position of the force-applying part is to be adjusted, the connecting rod needs to be detached from the output end, and the force-applying part needs to be detached from the connecting rod, and then the corresponding connecting rod needs to be replaced and connected between the output end and the force-applying part. Threaded parts are usually used to fasten the connecting rod and the output end, and between the connecting rod and the force-applying part. When disassembling and assembling the connecting rod and the force-applying part, there are many threaded parts, the operation is cumbersome, time-consuming and labor-intensive, and work efficiency is affected. In addition, a variety of connecting rods need to be equipped, and the management cost and site cost are high.

[0004] Therefore, it is necessary to improve the prior art to overcome the above defects in the prior art. Utility Model Content

The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0035] See also Figures 1 to 4As shown, a claw mechanism corresponding to a preferred embodiment of the utility model is used to be installed on the driving mechanism 400, so as to move along the disassembly direction of the battery pack 100 under the drive of the driving mechanism 400, thereby disassembling the outer shell of the battery pack 100. The driving mechanism 400 has two output ends that can move in opposite directions or towards each other, and the number of claw mechanisms is two, and they are fixedly connected to different output ends respectively. The outer shell of the battery pack 100 is formed by buckling two shells 110, and both shells 110 are provided with a force application area 120, and the force application area 120 corresponds to the claw mechanism one by one.

[0036] Furthermore, the claw mechanism includes a fixed seat 200 and a claw 300. The fixed seat 200 is fixedly connected to the output end of the driving mechanism 400. The fixed seat 200 can reciprocate along the driving direction. The claw 300 is adjustably connected to the fixed seat 200. The claw 300 can adjust its position on the fixed seat 200 in a direction perpendicular to the driving direction.

[0037] The utility model connects the pulling claw 300 to the fixing base 200 in an adjustably manner. When different types of battery packs 100 need to be adapted, only the position of the pulling claw 300 needs to be adjusted without disassembling and replacing the fixing base 200. The operation is simple and efficient, and no additional replacement parts are required, thereby effectively reducing management costs and site costs.

[0038] Further, in one embodiment, a first connection hole (not shown) is provided on the fixing seat 200, and a second connection hole (not shown) is provided on the pulling claw 300, and a locking member (not shown) can be provided between the first connection hole and the second connection hole to fasten the pulling claw 300 and the fixing seat 200. Preferably, there are a plurality of first connection holes, and they are spaced apart in a direction perpendicular to the driving direction, so that the pulling claw 300 can move relative to the fixing seat 200, so that the second connection hole corresponds to different first connection holes, thereby realizing that the position of the pulling claw 300 on the fixing seat 200 is adjustable.

[0039] In another embodiment, the fixed seat 200 and the claw 300 can also be slidably connected, one of the fixed seat 200 and the claw 300 is provided with a groove structure, and the other is provided with a sliding structure, the sliding structure can be slidably embedded in the groove structure, the sliding direction of the claw 300 is perpendicular to the driving direction of the driving mechanism 400, and the fixed seat 200 and the claw 300 are fastened by a locking member. With the sliding-matching claw 300 and the fixed seat 200, the claw 300 is easy to adjust and the connection between the two is more tightly.

[0040] Specifically, in this embodiment, the fixing seat 200 is provided with a slide groove 221 and an adjustment hole 222, the adjustment hole 222 extends from the outer surface of the fixing seat 200 to the slide groove 221, and there are a plurality of adjustment holes 222, which are arranged at intervals along the length direction of the slide groove 221. The claw 300 is partially engaged with the slide groove 221 and can slide along the length direction of the slide groove 221, and the locking member is penetrated in the adjustment hole 222 corresponding to the claw 300 to fasten the claw 300 to the slide groove 221, so as to achieve relative fixation of the claw 300 and the fixing seat 200.

[0041] Furthermore, the driving direction of the driving mechanism 400, the disassembly direction of the battery pack 100, and the width direction of the slide slot 221 are consistent and preferably in the horizontal direction, and the length direction of the slide slot 221 is preferably in the vertical direction perpendicular to the driving direction. In the depth direction of the slide slot 221, the force application area 120 and the claw mechanism are arranged opposite to each other, and the operator can push the battery pack 100 toward the claw mechanism so that the claw 300 is located between the two force application areas 120, and the driving mechanism 400 drives the two claw mechanisms to move in opposite directions, and the claw 300 contacts the force application area 120 and applies a disassembly force to the force application area 120, thereby separating the shell 110.

[0042] Furthermore, the fixing seat 200 includes a plate body 210 and a protrusion 220. The plate body 210 has a first plate surface 211 connected to the driving mechanism 400 and a second plate surface 212 opposite to the first plate surface 211. The protrusion 220 is convexly arranged on the second plate surface 212, and the slide groove 221 is formed by being recessed inward from the side of the protrusion 220 away from the second plate surface 212. The plate body 210 and the protrusion 220 can be integrally formed or separately formed and then fixed together. In this embodiment, they are preferably integrally formed to facilitate assembly and improve overall strength.

[0043] Furthermore, the protrusion 220 is preferably flush with the sides of the fixing seat 200 on both sides of the slide groove 221 in the length direction, and both ends of the slide groove 221 extend to the sides of the protrusion 220 to ensure the structural strength of the protrusion 220 while increasing the adjustment range of the claw 300.

[0044] Further, in the depth direction of the slide groove 221, the partial projection of the plate body 210 does not overlap with the projection of the protrusion 220, so as to form a mounting portion 213, and the mounting portion 213 is provided with at least one mounting hole 214 that passes from the first plate surface 211 to the second plate surface 212, and the output end of the driving mechanism 400 has a docking hole 451 that corresponds to the mounting hole 214 one by one, and a screw member can be provided between the mounting hole 214 and the docking hole 451 to fasten the plate body 210 and the output end. By adopting the above structure, the axial length of the mounting hole 214 can be effectively reduced while ensuring the recessed depth of the slide groove 221, so as to facilitate the installation of the screw member.

[0045] In this embodiment, there are two mounting portions 213, which are disposed on both sides of the plate body 210 in the width direction of the slide slot 221. Each mounting portion 213 is provided with a plurality of mounting holes 214, which are arranged at intervals along the length direction of the slide slot 221 to strengthen the connection strength between the plate body 210 and the driving mechanism 400.

[0046] Furthermore, since the force required to disassemble the battery pack 100 is usually large, the protrusion 220 fixed to the claw 300 is subjected to a large reaction force, and the protrusion 220 is in contact with the plate 210 only through one side, so the structural strength is poor and the protrusion 220 is easy to deform.

[0047] As a preferred embodiment, the fixing seat 200 further includes a reinforcing rib 230, which is connected between the mounting portion 213 and the protrusion 220, so as to effectively enhance the connection strength of the protrusion 220 and ensure that the protrusion 220 will not deform under the reaction force. Preferably, the reinforcing rib 230 extends from one side of the plate body 210 and / or the protrusion 220 to the other side along the length direction of the slide groove 221. The reinforcing rib 230 can be integrally formed with the mounting portion 213 and / or the protrusion 220 or assembled after being separately formed. In this embodiment, the reinforcing rib 230 is preferably integrally formed with the plate body 210 and the protrusion 220.

[0048] Furthermore, the slide groove 221 includes a T-shaped groove, a C-shaped groove and a concave groove, so that the width dimension inside the slide groove 221 is larger than the width dimension of the slot opening of the slide groove 221. In the present embodiment, the slide groove 221 is preferably a T-shaped groove, and the T-shaped groove has better structural strength than other forms of grooves. The slide groove 221 is an open end at least at one end in its length direction, and the claw 300 can be loaded into the slide groove 221 from the open end. Since the width dimension inside the slide groove 221 is larger than the width dimension of the slot opening of the slide groove 221, when the claw 300 is placed in the slide groove 221, it can prevent the claw 300 from falling out of the slot opening of the slide groove 221, effectively improving the tightness and connection strength of the connection between the two, and ensuring that the claw 300 can reliably disassemble the battery pack 100. Preferably, both ends of the slide groove 221 are open ends to facilitate the installation of the claw 300.

[0049] Furthermore, a limiting wall 223 is formed between the slot opening of the slot 221 and the two side walls of the slot 221, and the limiting wall 223 is arranged opposite to the bottom of the slot 221. The claw 300 includes a sliding portion 310 installed in the slot 221, and the outer contour of the sliding portion 310 is the same as the inner contour of the slot 221.

[0050] The adjustment hole 222 is located on at least one limiting wall 223, and passes through from the limiting wall 223 along the depth direction of the slide groove 221 to the outer surface of the fixing seat 200 that is away from the limiting wall 223. Since the slide groove 221 is formed on the protrusion 220 in this embodiment, the outer surface of the fixing seat 200 that is away from the limiting wall 223 is specifically the side of the protrusion 220 that is away from the limiting wall 223. By adopting the above arrangement of the adjustment hole 222, it is convenient for operators to operate the locking member, and since the pressing direction of the locking member is consistent with the depth direction, the pressing effect is better.

[0051] In one embodiment, the two limiting walls 223 are both provided with adjustment holes 222 , and locking members can be disposed in the adjustment holes 222 of the two limiting walls 223 to cooperate with the fastening sliding part 310 to improve the locking effect.

[0052] However, the above structure requires at least two locking members, which makes the operation of the operator more complicated. As a preferred embodiment, the adjustment hole 222 is only provided on one of the limiting walls 223 to reduce the number of locking members and improve the convenience of operation. According to the actual test results, the locking member can meet the conventional housing disassembly requirements by tightening the sliding part 310 on one side.

[0053] In one embodiment, the adjustment hole 222 is a circular hole, and the locking member is specifically a threaded member such as a bolt or a screw, which is threadedly connected to the adjustment hole 222 and abuts against the sliding portion 310 of the claw 300 in response to the tightening operation, thereby tightening the claw 300. Preferably, a fixing hole 311 may also be provided on the sliding portion 310 of the claw 300, and the locking member is at least threadedly connected to the fixing hole 311 to enhance the tightening effect of the claw 300.

[0054] However, with the above structure, the pull claw 300 has fewer adjustable positions. As a preferred embodiment, the adjustment hole 222 is a strip hole, and the hole length direction of the adjustment hole 222 is consistent with the length direction of the slide groove 221, so that when the sliding part 310 slides along the slide groove 221 for adjustment, multiple areas of a single adjustment hole 222 can correspond to the fixed hole 311, thereby increasing the adjustment range.

[0055] In this embodiment, the number of the fixing hole 311 is preferably one, and accordingly, the number of the locking member is also one, so as to facilitate the adjustment operation of the operator. When the claw 300 is slidably adjusted along the slide groove 221, the fixing hole 311 corresponds to one of the adjustment holes 222, and the locking member is penetrated in the adjustment hole 222 and is threadedly connected with the fixing hole 311, so as to achieve the fastening of the claw 300.

[0056] Preferably, the fixing hole 311 is a through structure in the depth direction of the slide groove 221 . After the locking member is locked in place, the end of the locking member abuts against the bottom of the slide groove 221 to further improve the fastening effect of the sliding portion 310 .

[0057] Preferably, the fixing seat 200 is provided with a countersunk hole 224 inwardly from the outer surface where the adjustment hole 222 is formed, and the countersunk hole 224 corresponds to the adjustment hole 222 one by one. When the locking member is tightened into place, the cap portion of the locking member is received in the countersunk hole 224 to prevent the pulling claw 300 from being limited due to the protrusion of the cap portion of the locking member relative to the protrusion 220. At the same time, it can also effectively protect the locking member and improve the aesthetics.

[0058] Furthermore, the claw 300 further includes an arm 320 and a claw 330. The sliding portion 310, the arm 320, and the claw 330 are preferably formed in one piece to ensure structural strength and facilitate assembly. The arm 320 is located outside the slide slot 221, and the arm 320 extends from one side of the sliding portion 310 located at the notch of the slide slot 221, and the claw 330 is located at the extended end of the arm 320.

[0059] In one embodiment, the extension direction of the arm 320 is consistent with the depth direction of the slide groove 221, and the claw 330 is located on one side of the arm 320 in the width direction of the slide groove 221. The claw 330 is suitable for contacting the force application area 120 of the battery pack 100 to apply a disassembly force thereto. However, with the above structure, the structural strength of the arm 320 in the width direction of the slide groove 221 is relatively low, and the arm 320 is easily deformed when the claw 300 applies a disassembly force to the battery pack 100.

[0060] Preferably, in this embodiment, the arm 320 extends from the side of the sliding portion 310 located at the notch of the slide groove 221 along the width direction of the slide groove 221, and the fixed seat 200 is in close contact with the arm 320 on a side facing away from the other limiting wall 223 therein to prevent the arm 320 from blocking the adjustment hole 222, and the claw 330 is located on the side of the arm 320 facing away from the protrusion 220, and extends from the extended end of the arm 320 along the depth direction of the slide groove 221.

[0061] By adopting the above structure, the structural strength of the arm 320 can be effectively improved. When the claw 300 applies a disassembly force to the battery pack 100, the arm 320 is not easily deformed in the width direction of the slide groove 221 due to the reaction force; when the claw 300 and the battery pack 100 are aligned along the depth direction of the slide groove 221, since the arm 320 and the fixing seat 200 are in close contact with each other over a large area, the arm 320 is not easily deformed in the depth direction of the slide groove 221 due to the collision with the battery pack 100.

[0062] Furthermore, the driving mechanism 400 may specifically adopt a double-head cylinder, a double-slider linear motor or a double-slider linear module, etc. In this embodiment, a double-slider linear module is preferably used, which has high moving position accuracy and reliable force application.

[0063] The driving mechanism 400 includes a base 410, a screw 420 rotatably connected to the base 410, a screw sleeve 430 sleeved on the screw 420 and a driving motor 440 drivingly connected to the screw 420, a mounting plate 450 is fixed on the screw sleeve 430, the first plate surface 211 of the fixing seat 200 is in contact with the mounting plate 450, and a docking hole 451 is provided on the mounting plate 450 so that the fixing seat 200 and the mounting plate 450 can be fastened together by a screw.

[0064] The axial direction of the screw 420 is consistent with the disassembly direction of the battery pack 100. The screw 420 is a bidirectional screw, which includes two rod portions with opposite thread rotation directions. There are two screw sleeves 430, which are respectively arranged on different rod portions. The fixing seat 200, the mounting plate 450 and the screw sleeves 430 correspond one by one.

[0065] Preferably, the driving mechanism 400 also includes a slide rail assembly 460 arranged along the axis direction of the screw rod 420 , and the slide rail assembly 460 is supported between the base 410 and the mounting plate 450 to guide the mounting plate 450 and the fixing seat 200 thereon to move smoothly along the axis direction of the screw rod 420 .

[0066] The slide rail assembly 460 includes a slide rail 461 fixedly connected to the base 410 and a slider 462 slidably connected to the slide rail 461. The slide rail 461 is provided with at least two sliders 462 to be respectively fixedly connected to different mounting plates 450. The number of slide rail assemblies 460 is preferably two groups, and they are respectively arranged on the upper and lower sides of the screw rod 420. The middle part of the mounting plate 450 is fixedly connected to the screw sleeve 430, and the upper and lower sides of the mounting plate 450 are respectively fixedly connected to the sliders 462 on different slide rails 461, thereby improving the connection stability of the mounting plate 450, so as to reliably transmit to the claw mechanism during the disassembly process of the battery pack 100.

[0067] Furthermore, the driving mechanism 400 also includes a travel switch 470 fixed on the top side of the base 410, wherein a limiter 480 is provided on the top side of a mounting plate 450 or a fixing seat 200, and the limiters 480 are two in number and are arranged at intervals along the axial direction of the screw 420, and the contact of the travel switch 470 is located between the two limiters 480 and on the moving path of the limiters 480, and the travel switch 470 is electrically connected to the driving motor 440 to transmit an electrical signal. When the claw mechanism moves toward each other, one of the limiters 480 can trigger the contact of the travel switch 470 to drive the claw mechanism to stop moving toward each other and be in the first extreme position; when the claw mechanism moves in the opposite direction, the other limiter 480 can trigger the contact of the travel switch 470 to drive the claw mechanism to stop moving in the opposite direction and be in the second extreme position. The operator can align the battery pack 100 with the claw mechanism in the first limit position, and disassemble the shell of the battery pack 100 in response to the claw mechanism moving from the first limit position to the second limit position. In addition, by adjusting the positions of the two limit members 480 in the axial direction of the screw 420, the first limit position and the second limit position can be adaptively adjusted to facilitate the alignment of the claw mechanism with different types of battery packs 100 and adapt to the disassembly stroke required by different types of battery packs 100.
