Description

Technical Field

[0001] This invention relates to the field of power battery recycling technology, and in particular to a milling and clamping fixture for battery cell modules. Background Technology

[0002] The rapid development of the new energy vehicle industry will inevitably lead to the rise of the retired power battery recycling industry. Cascade utilization is currently the mainstream treatment method for retired power batteries. The economic value generated by cascade utilization is far higher than that generated by directly scrapping battery cells. Moreover, in terms of environmental protection, the energy consumption and waste gas and waste liquid generated by cascade utilization are far lower than those generated by recycling.

[0003] For example, a clamping mechanism for a waste battery cell cutting device, as proposed in patent application number CN202322037227.0, includes two clamps. Each clamp includes a mounting plate and a positioning plate. The mounting plate includes a first horizontal plate for fixing to a base and a first vertical plate vertically fixed to the first horizontal plate. The positioning plate includes a second vertical plate slidingly on the first vertical plate in a vertical direction and a second horizontal plate vertically fixed to the top of the second vertical plate. A locking assembly is connected between the second vertical plate and the first vertical plate to fix the second vertical plate relative to the first vertical plate. This allows the battery cell to be fixed in both the horizontal X-axis direction and the vertical Z-axis direction.

[0004] However, the aforementioned clamping mechanism only fixes the battery cell in the XZ direction and cannot adjust the position of the battery cell in the Y direction; at the same time, when moving the clamping mechanism to the machine tool, it is necessary to adjust the relative position of the clamping mechanism and the machine tool, which is extremely inconvenient to use. Summary of the Invention

[0005] In view of this, it is necessary to provide a milling clamping fixture for battery cell modules to solve the problem that the existing clamping mechanism can only fix the battery cell in the XZ direction and cannot adjust the position of the battery cell in the Y direction; at the same time, when the clamping mechanism is moved to the machine tool, the relative position of the clamping mechanism and the machine tool needs to be adjusted, which is extremely inconvenient to use.

[0006] This invention provides a milling clamping fixture for battery cell modules, including a fixed clamping assembly and a centering positioning assembly. The fixed clamping assembly includes a sub-plate, an X-axis clamping member, and a Z-axis clamping member. The X-axis clamping member is mounted on the sub-plate and has an adjustable clamping gap along the horizontal X-axis direction. The Z-axis clamping member is mounted on the sub-plate and forms a clamping gap through the clamping gap between the sub-plate and the sub-plate. The centering positioning assembly includes a base plate and a Y-axis positioning member. The base plate is detachably connected to the sub-plate. The Y-axis positioning member has an adjustable centering positioning gap along the horizontal Y-axis direction. The horizontal X-axis and the horizontal Y-axis are perpendicular to each other. When the base plate and the sub-plate are connected, the centering positioning gap passes through the clamping gap. The mother plate is used for mounting on a machine tool and has a positioning connection point. The sub-plate is detachably connected to the mother plate.

[0007] Furthermore, the Y-axis positioning component includes two centering plates and a driving component. The two centering plates are arranged sequentially along the horizontal Y-axis direction and located on both sides of the clamping gap. Both centering plates are slidably connected to the base plate along the horizontal Y-axis direction. The driving component is mounted on the base plate, and the output end of the driving component is connected to the two centering plates for driving the two centering plates to slide.

[0008] Furthermore, the driving component includes a rotating block, two swing arms, and a hydraulic cylinder. The rotating block is rotatably connected to the base plate. The opposite ends of the two swing arms are hinged to the rotating block, and the opposite ends of the two swing arms are respectively hinged to the two centering plates. The fixed end of the hydraulic cylinder is hinged to the base plate, and the output end of the hydraulic cylinder is hinged to the rotating block.

[0009] Furthermore, it also includes a zero-point positioning component, which is disposed on the positioning connection point of the mother plate.

[0010] Furthermore, the zero-point positioning component includes a zero-point positioning male connector and a zero-point positioning female connector. The zero-point positioning male connector is installed at the bottom of the daughter plate, and the zero-point positioning female connector is installed at the top of the mother plate. The zero-point positioning male connector and the zero-point positioning female connector can be connected to form a vacuum cavity.

[0011] Furthermore, the number of zero-point positioning components is eight, with the eight zero-point positioning male heads arranged in a matrix array at the bottom of the daughter board and the eight zero-point positioning female heads arranged in a matrix array at the top of the mother board.

[0012] Furthermore, it also includes a support plate and an anti-detachment column disposed on the sub-plate, the support plate being located in the clamping gap, and the top end of the anti-detachment column being engaged in an anti-detachment hole opened at the bottom of the support plate.

[0013] Furthermore, the X-axis clamping member includes multiple X-axis adjusting seats and multiple push rods disposed opposite to each other on both sides of the sub-plate. The multiple push rods extend along the horizontal X-axis direction and pass through threaded holes opened on the multiple X-axis adjusting seats respectively. The clamping gap is formed between the multiple push rods on both sides.

[0014] Furthermore, the Z-axis clamping component includes multiple Z-axis adjusting seats, multiple sliding plates, multiple pressure plates, multiple guide rods, multiple drive rods, and multiple nuts disposed opposite to each other on both sides of the sub-plate. The multiple guide rods are vertically arranged, and the bottom ends of the multiple guide rods are respectively fixedly connected to the multiple Z-axis adjusting seats. The top ends of the multiple guide rods pass through the multiple sliding plates and are respectively connected to the multiple nuts, so as to limit the multiple sliding plates to slide in the vertical direction to any height position of the corresponding guide rod. The bottom of the multiple sliding plates on the side away from the clamping gap is respectively fixedly connected to the top ends of the multiple drive rods. The bottom ends of the multiple drive rods are respectively slidably connected to the multiple Z-axis adjusting seats. The side of the multiple sliding plates near the clamping gap is located above the clamping gap, and their bottoms are respectively fixedly connected to the multiple pressure plates.

[0015] Furthermore, it also includes multiple positioning support columns fixedly installed on both sides of the base plate, and multiple positioning holes are provided on the sub-plate, the top ends of the multiple positioning support columns can respectively cooperate with the multiple positioning holes to abut.

[0016] Compared with existing technologies, this method involves placing the battery cell module to be milled on the sub-board, hoisting the sub-board onto the base plate, adjusting the position of the battery cell module in the horizontal Y-axis direction using the Y-axis positioning component, and then adjusting and fixing the position of the battery cell module on the XZ axes using the X-axis clamping component and the Z-axis pressing component. At this point, the sub-board is hoisted onto the mother plate according to the positioning connection points of the mother plate. The relative position between the sub-board and the mother plate can be determined through the set positioning connection points. Then, connecting the sub-board and the mother plate completes the positioning of the battery cell module relative to the machine tool, which is convenient to use. Attached Figure Description

Detailed Implementation

[0018] Preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, which form part of this application and are used together with the embodiments of the present invention to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention.

[0019] like Figure 1-2 As shown, the milling clamping fixture for battery cell modules provided by the present invention includes a fixed clamping assembly 100 and a centering positioning assembly 200. The fixed clamping assembly 100 includes a sub-plate 110, an X-axis clamping member 120, and a Z-axis clamping member 130. The X-axis clamping member 120 is mounted on the sub-plate 110 and has an adjustable clamping gap along the horizontal X-axis direction. The Z-axis clamping member 130 is mounted on the sub-plate 110 and forms a clamping gap through the clamping gap between the sub-plate 110 and the sub-plate 110. The centering positioning assembly... 200 includes a base plate 210 and a Y-axis positioning component 220. The base plate 210 is detachably connected to the sub-plate 110. The Y-axis positioning component 220 has an adjustable centering positioning gap along the horizontal Y-axis direction. The horizontal X-axis and the horizontal Y-axis are arranged perpendicular to each other. When the base plate 210 and the sub-plate 110 are connected, the centering positioning gap passes through the clamping gap. The mother plate 300 is used to be mounted on the machine tool. The mother plate 300 has a positioning connection point. The sub-plate 110 is detachably connected to the mother plate 300.

[0020] During implementation, the battery cell module to be milled is placed on the sub-plate 110, and the sub-plate 110 is hoisted onto the base plate 210. After adjusting the position of the battery cell module in the horizontal Y-axis direction using the Y-axis positioning component 220, the position of the battery cell module in the X-Z axis is adjusted and fixed using the X-axis clamping component 120 and the Z-axis pressing component 130. At this time, the sub-plate 110 is hoisted onto the mother plate 300 according to the positioning connection points of the mother plate 300. The relative position between the sub-plate 110 and the mother plate 300 can be determined by the set positioning connection points. At this time, connecting the sub-plate 110 and the mother plate 300 completes the positioning of the battery cell module relative to the machine tool, which is convenient to use.

[0021] In this embodiment, the fixing and clamping assembly 100 is used for pre-positioning and fixing the battery cell module. Specifically, the battery cell module to be milled is first placed on the base plate 210. At this time, the X-axis clamping member 120 and the Z-axis clamping member 130 do not fix the battery cell module, thus achieving the pre-positioning function. After the Y-axis positioning member 220 adjusts the Y-axis orientation of the battery cell module, the fixing and clamping assembly 100 then fixes and clamps the battery cell module, thereby achieving the positioning and fixing of the battery cell module along the X-axis and Y-axis directions.

[0022] To accommodate battery cell modules of varying thicknesses, one embodiment includes a support plate 140 and an anti-detachment post 111 disposed on the sub-board 110. The support plate 140 is located within the clamping gap, and the top end of the anti-detachment post 111 is engaged in an anti-detachment hole at the bottom of the support plate 140. By replacing the support plate 140 with one of different thicknesses, the Z-axis clamping member 130 can be adapted to battery cell modules of varying thicknesses. Simultaneously, the anti-detachment post 111 is used to position the support plate 140 along the X-axis and Y-axis directions. Of course, in other preferred embodiments, the two sides of the support plate 140 may abut against the X-axis clamping member 120 and / or the Z-axis clamping member 130 to achieve positioning of the support plate 140; this is not limited.

[0023] like Figure 3 As shown, in one embodiment, the X-axis clamping member 120 includes a plurality of X-axis adjusting seats 121 and a plurality of push rods 122 disposed opposite to each other on both sides of the subplate 110. The plurality of push rods 122 extend along the horizontal X-axis direction and are respectively disposed through threaded holes opened on the plurality of X-axis adjusting seats 121, forming a clamping gap between the plurality of push rods 122 on both sides.

[0024] like Figure 3 As shown, in one embodiment, the Z-axis clamping member 130 includes multiple Z-axis adjusting seats 131, multiple sliding plates 132, multiple pressure plates 133, multiple guide rods 134, multiple drive rods 135, and multiple nuts 136 disposed opposite to each other on both sides of the sub-plate 110. The multiple guide rods 134 are vertically arranged, and the bottom ends of the multiple guide rods 134 are respectively fixedly connected to the multiple Z-axis adjusting seats 131. The top ends of the multiple guide rods 134 pass through the multiple sliding plates 132 and are respectively connected to the multiple nuts 136, so as to limit the multiple sliding plates 132 to slide in the vertical direction to any height position of the corresponding guide rod 134. The bottom of the multiple sliding plates 132 on the side away from the clamping gap is respectively fixedly connected to the top ends of the multiple drive rods 135. The bottom ends of the multiple drive rods 135 are respectively slidably connected to the multiple Z-axis adjusting seats 131. The side of the multiple sliding plates 132 near the clamping gap is located above the clamping gap, and its bottom is respectively fixedly connected to the multiple pressure plates 133.

[0025] Of course, in another embodiment, a battery and a cylinder can be installed on the sub-plate 110 to drive the push rod 122 and the pressure plate 133 to move, replacing manual labor.

[0026] like Figure 5As shown, after the battery cell module is pre-installed, the sub-board 110 needs to be transferred to the base plate 210. In order to facilitate the control of the relative position between the sub-board 110 and the base plate 210 when they are connected, in one embodiment, a plurality of positioning support columns 230 are fixedly set on both sides of the base plate 210. The sub-board 110 is provided with a plurality of positioning holes 112, and the top ends of the plurality of positioning support columns 230 can respectively engage with the plurality of positioning holes 112.

[0027] In this embodiment, the centering and positioning component 200 is used to adjust the position of the battery cell module on the sub-board 110 along the horizontal Y-axis direction.

[0028] like Figure 4 As shown, in one embodiment, the Y-axis positioning member 220 includes two centering plates 221 and a driving member 222. The two centering plates 221 are arranged sequentially along the horizontal Y-axis direction and located on both sides of the clamping gap. Both centering plates 221 are slidably connected to the base plate 210 along the horizontal Y-axis direction. The driving member 222 is mounted on the base plate 210, and the output end of the driving member 222 is connected to the two centering plates 221 for driving the two centering plates 221 to slide.

[0029] Among them, the centering plate 221 is a vertically arranged flat plate. By sliding the two centering plates 221 along the Y-axis, the position of the battery cell module in the Y-axis direction can be adjusted.

[0030] In one embodiment, the drive component 222 includes a rotating block 222a, two swing arms 222b, and a hydraulic cylinder 222c. The rotating block 222a is rotatably connected to the base plate 210. The opposite ends of the two swing arms 222b are hinged to the rotating block 222a, and the opposite ends of the two swing arms 222b are respectively hinged to the two centering plates 221. The fixed end of the hydraulic cylinder 222c is hinged to the base plate 210, and the output end of the hydraulic cylinder 222c is hinged to the rotating block 222a.

[0031] It also includes two connecting arms 222d, which extend along the Y-axis. The opposite ends of the two connecting arms 222d are fixedly connected to the two centering plates 221, and the opposite ends of the two connecting arms 222d are hinged to the two swing arms 222b.

[0032] After the battery cell module is fixedly clamped and positioned, the daughter board 110 needs to be transferred from the base plate 210 to the mother board 300. It is understood that lifting rings can be installed on the daughter board 110 to facilitate the transfer using a crane; alternatively, in other embodiments, a forklift can be used. In this case, four placement feet 113 can be provided at the four corners of the base plate 210 of the daughter board 110 to allow the forklift's forks to insert under the daughter board 110. For small and lightweight battery cell modules, manual handling can also be used.

[0033] In this embodiment, the motherboard 300 is mounted on the machine tool, and the position of the motherboard 300 relative to the machine tool is fixed. Therefore, it is only necessary to control the connection position between the daughterboard 110 and the motherboard 300 to achieve the positioning between the daughterboard 110 and the machine tool.

[0034] like Figure 6 As shown, in one embodiment, a zero-point positioning element 310 is also included, which is disposed on the positioning connection point of the mother plate 300.

[0035] In this embodiment, the zero-point positioning component 310 includes a zero-point positioning male connector 311 and a zero-point positioning female connector 312. The zero-point positioning male connector 311 is installed on the bottom of the daughter plate 110, and the zero-point positioning female connector 312 is installed on the top of the mother plate 300. The zero-point positioning male connector 311 and the zero-point positioning female connector 312 can be connected to form a vacuum cavity.

[0036] The number of zero-point positioning components 310 is eight. The eight zero-point positioning male heads 311 are arranged in a matrix array at the bottom of the daughter plate 110, and the eight zero-point positioning female heads 312 are arranged in a matrix array at the top of the mother plate 300.

[0037] By connecting the vacuum chamber with a vacuum pump or other equipment, negative pressure can be generated between the zero-point positioning male connector 311 and the zero-point positioning female connector 312, thereby achieving the connection between the daughter board 110 and the mother board 300. Of course, in other preferred embodiments, the connection between the daughter board 110 and the mother board 300 can also be achieved by means of clips, screws, etc., and there is no limitation on this.

[0038] Compared with existing technologies: The battery cell module to be milled is placed on the sub-plate 110, and the sub-plate 110 is hoisted onto the base plate 210. After adjusting the position of the battery cell module in the horizontal Y-axis direction by the Y-axis positioning component 220, the position of the battery cell module in the X-Z axis is adjusted and fixed by the X-axis clamping component 120 and the Z-axis pressing component 130. At this time, the sub-plate 110 is hoisted onto the mother plate 300 according to the positioning connection points of the mother plate 300. The relative position between the sub-plate 110 and the mother plate 300 can be determined by the set positioning connection points. At this time, connecting the sub-plate 110 and the mother plate 300 can complete the positioning of the battery cell module relative to the machine tool, which is convenient to use.

[0039] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention.
