Description

Technical Field

[0001] This utility model relates to the field of lithium battery casing cutting and processing technology, and in particular to a lithium battery casing disassembly and cutting assembly. Background Technology

[0002] Disassembling and cutting the lithium battery casing can separate the metal (steel / aluminum) from the internal materials (lithium, cobalt, graphite), improving the recycling rate.

[0003] Patent document with announcement number (CN222711124U) discloses a cutting assembly for lithium battery casings, including a base, a cutting mechanism fixedly installed on the outer center of the base, a transverse positioning mechanism fixedly installed on the top of the base on one side of the cutting mechanism, and a longitudinal positioning mechanism fixedly installed on the back of the base on the side away from the transverse positioning mechanism. The inner sides of the transverse and longitudinal positioning mechanisms hold a cylindrical casing. By setting up the cutting mechanism, efficient and uniform cutting of the cylindrical lithium battery casing can be achieved. When the electric push rod is activated, the laser cutting head moves downward and approaches the casing. At the same time, the fourth motor is activated, and the second motor drives the transmission pulley to rotate. Through the transmission belt, the two sets of transmission pulleys are synchronously driven, which in turn drive a set of drive rollers to rotate, causing the cylindrical casing to rotate. During the rotation of the casing, the laser cutting head is activated to perform a 360-degree cut on the outer surface of the casing, ensuring uniform processing of the casing and improving the cutting quality and efficiency.

[0004] When using the above-mentioned technology, the following technical problems were found in the existing technology: Although laser cutting can prevent hidden damage to the internal structure of the battery casing (such as the separator) due to compression, if there is grease, dirt or other contaminants on the surface of the lithium battery casing, laser cutting may result in an uneven cut surface, or even burrs and slag. In addition, when disassembling multiple sides of the casing of a square lithium battery, it is necessary to manually change the sides and perform secondary positioning and calibration before continuing to cut the casing. To address these issues, a lithium battery casing disassembly and cutting component is designed to provide an alternative technical solution. Summary of the Invention

[0016] A set of cleaning components on the first clamping part is disposed between the first abutting component and a set of rods. The first abutting component is used to drive the cleaning component closer to another cleaning component along the X-axis.

[0017] As a preferred embodiment of the lithium battery casing disassembly and cutting assembly provided by this utility model, the second clamping part further includes a second clamping member disposed opposite to the first clamping member, and a set of cleaning members on the second clamping part is disposed between the first clamping member and the second clamping member.

[0018] As a preferred embodiment of the lithium battery casing disassembly and cutting assembly provided by this utility model, both the first clamping member and the second clamping member are composed of at least one dual-axis cylinder.

[0019] Both sets of cleaning components consist of a second connector and an adhesive strip provided on the detachable portion of the second connector; a portion of the second connector is fixedly connected to the pushing part of the dual-axis cylinder;

[0020] The second connector consists of a rail groove and a guide rail detachably connected to the rail groove, with the rubber strip fixedly connected to the guide rail.

[0039] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0040] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0041] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] like Figure 1 and Figure 3 As shown, this lithium battery casing disassembly and cutting assembly includes a base 1, a laser cutting mechanism 3, a fixing mechanism 4, a rotating mechanism 6, and a pushing mechanism 7. The laser cutting mechanism 3 is fixed to the base 1 by a first bracket 2. The laser cutting mechanism 3 is used to cut the surface of the lithium battery casing by irradiating it with a laser beam. The fixing mechanism 4 is connected to the rotating mechanism 6 by a third connector 67 and is suspended above the base 1. The fixing mechanism 4 is used to fix square lithium batteries of any size, so as to stably accept the cutting of the laser cutting mechanism 3, so that the internal materials of the battery are separated from the casing and then recycled separately.

[0044] In order to cut the square lithium battery casing without affecting the internal materials, the laser cutting mechanism 3 needs to move along the outer periphery of the casing. However, the laser cutting mechanism 3 is limited to moving only along the X and Y axes as shown in the figure, which means that only the upward-facing side can be cut. Moreover, cutting one side is not enough to remove the internal materials. Therefore, the fixed mechanism 4 connected to it rotates under the drive of the rotating mechanism 6, so that the casing on the fixed mechanism 4 rotates by, for example, 90 degrees and switches the adjacent side to face upward for the laser cutting mechanism 3 to cut. By repeating this action multiple times, the casing can be partially cut off from the lithium battery body so that the internal materials can be separated from the casing.

[0045] In order to arbitrarily cut the length of the lithium battery casing in the Z-axis direction, the casing on the fixed mechanism 4 is subjected to force by the propulsion mechanism 7 through the rotation mechanism 6, so that the casing moves closer to the laser cutting mechanism 3 along the Z-axis under the drive of the propulsion mechanism 7. The cutting position of the laser cutting mechanism 3 on the casing is adjusted by controlling the propulsion stroke.

[0046] Furthermore, such as Figure 2 As shown, and with reference Figure 1 The laser cutting mechanism 3 consists of a base 31 fixed on the first support 2, a moving module connected to the base 31, and a laser cutting head 32 connected to the moving module. The laser cutting head 32 is used to emit a laser beam, as detailed in the prior art. Driven by the moving module, the laser cutting head 32 moves linearly along the X and / or Y axes to the base 31. For example, the downward movement along the X axis brings the laser cutting head 32 closer to the lithium battery casing, while the movement along the Y axis moves the laser cutting head 32 along the width direction of the lithium battery casing, thereby allowing the laser cutting head 32 to complete the cutting of the upper side of the lithium battery casing.

[0047] Furthermore, the moving module includes a Y-axis slide 33 fixed on the base 31 and an X-axis slide 34 connected to the Y-axis slide 33. The laser cutting head 32 is fixedly connected to the bottom of the X-axis slide 34. Specifically, the Y-axis slide 33 and the X-axis slide 34 are either ball screw, rack and pinion, or synchronous belt drive. The figure shows that the Y-axis slide 33 is a linear slide with rack and pinion drive and the X-axis slide 34 is a linear slide with synchronous belt drive. The specific structure of the slide can be found in the prior art, which includes, but is limited to, a platform, the transmission structure described above, a guide group, and a slide seat that is driven by the transmission structure and moves linearly and reciprocally on the guide group via a slider.

[0048] like Figure 4 As shown, and with reference Figure 1 and Figure 3The fixing mechanism 4 consists of a first clamping part 41 and a second clamping part 42, which are connected as a whole by a first connector 43. The clamping directions of the first clamping part 41 and the second clamping part 42 are staggered. Specifically, the first clamping part 41 provides clamping movement in the X-axis direction as shown in the figure, and achieves vertical fixation of the lithium battery casing in the height direction through this movement. The second clamping part 42 provides clamping movement in the Y-axis direction as shown in the figure, and achieves lateral fixation of the lithium battery casing in the width direction through this movement. Thus, under the clamping and fixing in the height and width directions, the lithium battery casing is stably placed on the fixing mechanism 4 as a whole.

[0049] Cleaning components 5 (details below) are provided on the movable parts of the first clamping part 41 and the second clamping part 42. The cleaning components 5 are used to abut against the lithium battery casing under the action of the first clamping part 41 or the second clamping part 42. When the pushing mechanism 7 moves the lithium battery casing along the Z-axis, the cleaning components 5 passively change their position against the outer surface of the lithium battery casing, thereby allowing the cleaning components 5 to perform a wiping action on the outer surface of the casing to remove contaminants. This improves the cutting effect of the laser cutting mechanism 3 on the casing, as contaminants absorb laser energy, leading to incomplete cutting or uneven cutting edges, resulting in burrs and slag.

[0050] like Figure 5 As shown, and with reference Figure 1 , Figure 3 and Figure 4 The rotating mechanism 6 includes a support base 61, a connecting ring 62 integrally connected to the support base 61, a transmission component connected between the support base 61 and the connecting ring 62, and a reduction motor 63 that drives the transmission component. Part of the transmission component is connected to the first connecting member 43 through a third connecting member 67. The reduction motor 63 drives the transmission component, and the transmission component then rotates the first clamping part 41 and the second clamping part 42, which are integrally connected by the first connecting member 43, through the third connecting member 67. This causes the lithium battery casing clamped and fixed on the first clamping part 41 and the second clamping part 42 to rotate 90 degrees, so that the other side of the lithium battery casing rotates upward.

[0051] Furthermore, the transmission component includes a driven ring 64 connected to the connecting ring 62 via a bearing, a driving wheel 65 coaxially connected to the geared motor 63, and a belt 66 sleeved between the driven ring 64 and the driving wheel 65. A third connecting member 67 is fixedly disposed on one side of the driven ring 64. The geared motor 63 drives the driving wheel 65, which in turn drives the driven ring 64 to rotate via the belt 66. The driven ring 64 rotates on the connecting ring 62 via a bearing and drives the first clamping part 41 and the second clamping part 42 to rotate via the third connecting member 67.

[0052] In some embodiments (not shown in the figures), the transmission component includes a large gear rotatably connected to the connecting ring 62, and a small gear meshing with the large gear and coaxially connected to the geared motor 63. Specifically, the large gear is circular and radially hollow, so it can be connected to the connecting ring 62 through a bearing. Under the transmission of the small gear driven by the geared motor 63, the large gear rotates on the connecting ring 62. The third connecting member 67 is connected to the large gear.

[0053] like Figure 6 As shown, and with reference Figure 5 The propulsion mechanism 7 includes a brake and a push plate 71. The brake is used to connect the push plate 71 through the connecting ring 62 and can drive the push plate 71 to move through the connecting ring 62 to push the housing on the fixing mechanism 4, so that the housing changes position on the fixing mechanism 4.

[0054] Furthermore, the braking component is preferably a pen-shaped cylinder 72 arranged along the Z-axis direction. The push plate 71 is fixedly connected to the piston shaft of the pen-shaped cylinder 72. The propulsion mechanism 7 also includes a second bracket 73 that carries the pen-shaped cylinder 72, and a set of guide rods 74 that keep the push plate 71 stable and pushed by the piston shaft. The pen-shaped cylinder 72 is fixed along the Z-axis direction by the second bracket 73. The push plate 71 is driven to move towards the fixing mechanism 4 by the pen-shaped cylinder 72. At the same time, the set of guide rods 74 connected to the push plate 71 slides on the second bracket 73.

[0055] like Figure 7 As shown (taking the first clamping part 41 as an example in the figure), and referring to Figure 4 The first clamping part 41 and the second clamping part 42 are both composed of a set of rods 44 connected to the first connecting member 43 and a first abutting member disposed between the set of rods 44. A set of cleaning members 5 on the first clamping part 41 are disposed between the first abutting member and the set of rods 44. The first abutting member drives the cleaning member 5 on it to move closer to another cleaning member 5 on the lower set of rods 44 as it moves downward along the X-axis. When the outer shell is located on the set of cleaning members 5, the outer shell is clamped and fixed in the vertical direction as the upper cleaning member 5 descends.

[0056] The figure does not show a further enlargement, but it can be understood from the description and reference to the first clamping part 41 that the second clamping part 42, based on the existing first clamping part 41, also includes a second abutment disposed opposite to the first abutment. That is, the second abutment and a set of rods 44 are both rotated 90 degrees and arranged, and the second abutment and the first abutment are arranged to be opposite each other to each other. A set of cleaning members 5 on the second clamping part 42 is disposed between the first abutment and the second abutment. The first abutment and the second abutment respectively drive the cleaning members 5 to move closer to the center along the X-axis. When the outer shell is located in the set of cleaning members 5, the outer shell is clamped and fixed in the left and right directions as the cleaning members 5 move in the lateral directions.

[0057] Furthermore, the first and second clamping members are preferably composed of at least one (two are shown in the figure, but not limited to this) dual-axis cylinder 45, which drives the cleaning member 5 to move linearly in the up-down or left-right directions.

[0058] like Figure 8 As shown, and with reference Figure 7 Both sets of cleaning components 5 are composed of a second connector 51 and a rubber strip 52 provided on the detachable part of the second connector 51. Part of the second connector 51 is fixedly connected to the pushing part of the dual-axis cylinder 45. The rubber strip 52 is elastic and preferably made of rubber. When clamped and fixed, it can flexibly contact the shell to avoid indentation on the shell surface. At the same time, when subjected to a certain Z-axis radial thrust (provided by the pushing mechanism 7), the bottom contact surface of the rubber strip 52 will be twisted and deformed to reduce the contact area with the shell, so as to minimize the frictional movement on the shell surface. The movement of the rubber strip 52 on the shell surface will have a wiping effect on the shell, thereby wiping away contaminants on the shell surface.

[0059] Furthermore, the second connector 51 consists of a rail groove 511 and a guide rail 512 detachably connected to the rail groove 511, with the adhesive strip 52 fixedly connected to the guide rail 512. After cleaning the housing multiple times, the adhesive strip 52 can be detached from the rail groove 511 via the guide rail 512. The guide rail 512 and the adhesive strip 52 are preferably connected by screws, so that the adhesive strip 52 can be detached and replaced by removing the screws on the guide rail 512, and the guide rail 512 can be reused repeatedly.

[0060] The preferred embodiments of this utility model disclosed above are merely illustrative of the present utility model. These preferred embodiments do not exhaustively describe all details, nor do they limit the present utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of the present utility model, thereby enabling those skilled in the art to better understand and utilize it. The present utility model is limited only by the claims and their full scope and equivalents.
