[0023] It is understandable that, referring to Figures 1 to 6 The embodiment of the first aspect of the present invention proposes a battery shell processing fixture, which realizes precise fixation and internal support of the battery shell 100 through reasonable structural design, effectively prevents deformation of the battery shell 100 during processing, and improves processing accuracy.

[0024] The battery shell processing fixture mainly includes two parts: a base 200 and an inner support assembly 300. The base 200 serves as the foundation of the entire fixture and provides a stable support platform, while the inner support assembly 300 is responsible for providing support inside the battery shell 100 to prevent its deformation.

[0025] A bottom support 210 is provided in the middle of the base 200, and the bottom support 210 is used to support the bottom surface of the battery shell 100. The shape and size of the bottom support 210 match the bottom surface of the battery shell 100 to ensure that the battery shell 100 can be placed stably on the base 200. The bottom support 210 can also be a plurality of dispersed blocks, which can be made of metal, plastic and other materials to increase the support stability between the bottom surface of the battery shell 100, and support the battery shell 100 at multiple points to prevent deformation during processing. Stands 220 are provided on both sides of the base 200, and the height of the stand 220 can be designed and adjusted according to the height of the battery shell 100. A plurality of edge fixing components are provided on the stand 220, and the edge fixing components are used to fix the edge of the battery shell 100. The edge fixing components can include fasteners such as clamping devices and bolts, and by adjusting these fasteners, the edge of the battery shell 100 can be tightly fixed.

[0026] The inner support assembly 300 is located above the bottom support portion 210, and the inner support assembly 300 includes a main frame 310, a plurality of legs 320, a plurality of upper support members 330, and a plurality of lower support members 340. The main frame 310 is composed of a plurality of cross bars 311 and a plurality of longitudinal bars 312, the cross bars 311 are arranged along the length direction of the battery shell 100, and the longitudinal bars 312 are arranged along the width direction of the battery shell 100. The above structure enables the main frame 310 to adapt to the internal shape of the battery shell 100, and provides a stable support platform for the legs 320, the upper support members 330, and the lower support members 340. The legs 320 are fixed to the bottom surface of the main frame 310 and abut against the inner bottom wall of the battery shell 100. The number and position of the legs 320 can be adjusted according to the shape and size of the battery shell 100 to ensure that the legs 320 can be evenly distributed on the inner bottom wall of the battery shell 100 to provide a stable support force.

[0027] The upper support member 330 is connected to the main frame 310 and is used to abut against the inner wall of the battery shell 100. The number and position of the upper support members 330 can be adjusted according to the shape of the inner wall of the battery shell 100 to ensure that the upper support member 330 can fully support the inner wall of the battery shell 100 to prevent the battery shell 100 from deforming during processing.

[0028] The lower support member 340 is connected to the main frame 310 or the support leg 320 to provide additional support. The lower support member 340 is provided with a pressing portion 341, which can abut against the inner bottom wall and / or inner side wall of the battery case 100. Figure 3 As shown, the connection between the inner bottom wall and the inner side wall of the battery shell 100 has a transition slope, and the pressing part 341 supports the transition slope. By adjusting the position and angle of the lower support component 340, support for different parts of the battery shell 100 can be achieved, further improving the processing accuracy.

[0029] like Figure 2 As shown, when using the battery shell processing fixture of the present invention, the battery shell 100 is first placed on the bottom support portion 210 of the base 200, and then the edge of the battery shell 100 is tightly fixed by adjusting the edge fixing assembly on the stand 220. Next, the inner support assembly 300 is placed inside the battery shell 100, and the support legs 320 abut against the inner bottom wall of the battery shell 100, the upper support component 330 abuts against the inner side wall of the battery shell 100, and the pressing portion 341 of the lower support component 340 abuts against the inner bottom wall and / or inner side wall of the battery shell 100, so as to achieve internal support for the battery shell 100.

[0030] During the processing, since the battery shell 100 is accurately fixed on the base 200 and is fully supported inside, the battery shell 100 can be effectively prevented from being deformed. At the same time, since the structural design of the internal support assembly 300 is reasonable, it can ensure that the battery shell 100 maintains a stable shape and size during the processing, thereby improving the processing accuracy.

[0031] The technical effects of the battery shell processing fixture are as follows: 1. Precise fixation: The battery shell 100 can be precisely fixed by the bottom support 210 on the base 200 and the edge fixing assembly on the stand 220. The design of the inner support assembly 300 allows the battery shell 100 to be fully supported internally. The synergistic effect of the support legs 320, the upper support component 330 and the lower support component 340 can effectively prevent the battery shell 100 from being deformed during processing, thereby improving the processing accuracy.

[0032] 2. Easy operation: The structure design of the clamp is reasonable and easy to operate. During use, the battery shell 100 only needs to be placed on the base 200, and the battery shell 100 can be fixed and supported by adjusting the edge fixing component and the inner support component 300, which not only saves time but also reduces the difficulty of operation.

[0033] 3. Improve processing efficiency: Since the fixture can achieve accurate fixation and internal support of the battery case 100, the processing efficiency can be greatly improved. At the same time, since the processing accuracy is improved, the scrap rate and rework rate can be reduced, further reducing the production cost.

[0034] Reference Figure 6In some embodiments of the present invention, the upper support component 330 includes a fixed seat 331, a sliding rod 332, a pressing block 333 and a driving mechanism 334. The fixed seat 331 is the installation base of the upper support component 330, and is designed with suitable mounting holes so that it can be fixed to the cross bar 311 of the main frame 310 by bolts or other fasteners. The design of the fixed seat 331 must ensure sufficient strength and rigidity to withstand various forces and vibrations generated during the processing. The fixed seat 331 is provided with a slide rail or a slide groove so that the sliding rod 332 can slide. A pressing block 333 is provided at one end of the sliding rod 332 for directly contacting and pressing the battery shell 100. The other end of the sliding rod 332 is connected to the driving mechanism 334 to realize the reciprocating motion of the sliding rod 332. The upper support component 330 is essentially a quick clamp, and reference can be made to Chinese patents: CN208744623U, CN208744627U, etc. The pressing block 333 is usually made of rubber, plastic or other soft materials to reduce damage to the battery case 100 and ensure the firmness of the clamping.

[0035] Refer to 4 and Figure 6 In some embodiments of the present invention, a plurality of matching top blocks 350 are connected to the stand 220, and the matching top blocks 350 correspond to the upper support member 330 one by one, and the positions also match each other to achieve the clamping of the battery shell 100. The matching top block 350 is located on the outside of the battery shell 100, and the pressing block 333 of the upper support member 330 is located on the inside of the battery shell 100. The two cooperate to clamp the battery shell 100 to prevent the battery shell 100 from deforming during processing. The matching top block 350 is usually made of hard material to ensure that it has sufficient strength and wear resistance.

[0036] Reference Figure 6 In some embodiments of the present invention, the lower support component 340 includes a connecting plate 342, a pressing portion 341 and a screw. The connecting plate 342 is the main part of the lower support component 340, and is designed to have sufficient strength and rigidity to withstand the force and vibration generated during the processing. A screw fixing hole is provided at the upper end of the connecting plate 342. The screw passes through the screw fixing hole on the connecting plate 342 and extends into the long groove on the side of the crossbar 311. The long groove is T-shaped, and the cap head of the screw is located in the long groove. By adjusting the position of the screw in the long groove, the position of the lower support component 340 can be adjusted to adapt to battery shells 100 of different sizes, and then the nut on the screw can be tightened to fix the connecting plate 342. The pressing portion 341 is fixed to the lower end of the connecting plate 342 by a support rod, and is used to directly contact and support the battery shell 100. The shape and size of the pressing portion 341 need to be customized according to the shape of the battery shell 100 to ensure that it can evenly distribute pressure and avoid damage to the battery shell 100.

[0037] According to the size and shape of the battery case 100 , the position of the sliding rod 332 of the upper support member 330 and the position of the screw of the lower support member 340 are adjusted to ensure that the clamp can firmly clamp the battery case 100 .

[0038] It is understandable that the edge fixing assembly of the battery shell processing fixture includes a plurality of side fixing mechanisms 230 and a plurality of top fixing mechanisms 240. This design is intended to fix the battery shell 100 in all directions to ensure the stability of the battery shell 100 during processing, thereby improving processing accuracy and efficiency. The side fixing mechanism 230 is mainly responsible for fixing the edges at both ends of the battery shell 100. In practical applications, the battery shell 100 usually has a rectangular or approximately rectangular inner cavity, and its two end edges need to be precisely fixed to avoid processing errors. The top edge fixing mechanism 240 focuses on fixing the top edge of the battery shell 100. Since the top of the battery shell 100 contains an opening and requires specific processing, the design of the top edge fixing mechanism 240 needs to consider sufficient flexibility and adaptability to ensure that the top edge will not be deformed or misaligned during processing.

[0039] Reference Figure 2 and Figure 3 The side fixing mechanism 230 includes a first driving component 231 and a first supporting plate 232 fixed to the base 200. The first driving component 231 can be a cylinder or an electric push rod, and is connected to the first pressing plate 233 through a mechanical connection. The first driving component 231 pushes or pulls the first pressing plate 233 to move along a preset path until it cooperates with the first supporting plate 232 to clamp the edge of the battery shell 100 together.

[0040] In particular, the end surface of the first support plate 232 abutting the battery shell 100 is designed to be a split structure. For example, the first support plate 232 has two surfaces abutting the battery shell 100, one surface cooperates with the first pressure plate 233, and the other surface supports the battery shell 100, thereby enhancing the support and positioning of the battery shell 100.

[0041] Reference Figure 2 and Figure 3The top edge fixing mechanism 240 includes a second driving component 241 and a second support plate 242 fixed to the base 200. The second driving component 241 is connected to a second pressing plate 243, which is used to cooperate with the second support plate 242 to clamp the top edge of the battery shell 100. The abutting surface of the second pressing plate 243 is designed to be an inclined surface to match the top edge shape of the battery shell 100. The second support plate 242 uses a hard block as a component that abuts the battery shell 100. The hard block adapts to the shape of the surface of the battery shell 100 to ensure the uniformity and stability of the clamping. In addition, the hard block also has a thickness adjustment structure, which allows the user to adjust the position of the hard block according to the thickness of the battery shell 100, thereby further optimizing the clamping effect. The thickness adjustment structure includes gaskets of various thicknesses. The hard block is connected to the second support plate 242 by a pin. According to the needs, a gasket with appropriate thickness can be selected and mounted on the pin, which is simple and easy to use.

[0042] It is understandable that in order to prevent the battery case 100 from being installed upside down and ensure accurate processing, the battery case processing fixture is designed with an anti-reverse mechanism. Figure 2 The anti-reverse mechanism includes a first vertical plate 251 and a second vertical plate 252, which can effectively prevent the battery shell 100 from being installed in reverse during the installation process and has an anti-mistake function.

[0043] The first vertical plate 251 abuts against one end of the battery case 100, playing a basic positioning and supporting role. The second vertical plate 252 is specially designed to abut against the protrusion at one end of the battery case 100, which is a part of the battery case 100 and is used to distinguish the two ends of the battery case 100. By precisely matching the shape and size of the protrusion of the battery case 100, the second vertical plate 252 can ensure that the battery case 100 can only be installed in the correct way, effectively preventing reverse installation.

[0044] It is understandable that, referring to Figure 2 The bottom surface of the base 200 is provided with a plurality of positioning seats 260. The function of the positioning seats 260 is to fix the battery shell processing fixture on the workbench of the laser cutting equipment. The bottom surface of each positioning seat 260 is provided with an eccentric positioning hole. The workbench is provided with a positioning pin that matches the positioning hole, so as to accurately position the battery shell processing fixture. Usually, the positioning seat 260 is connected to a sleeve, and a positioning hole is formed in the sleeve, which is easy to replace after the sleeve is worn.

[0045] In addition, a lifting ring 261 is provided at the upper end of the positioning seat 260. The existence of the lifting ring 261 allows the fixture to be easily moved and positioned by a lifting device, greatly simplifying the handling and installation process of the fixture. This is particularly important in a production environment where fixtures need to be frequently replaced or transferred between different workstations.

[0046] Reference Figure 1The embodiment of the second aspect of the present invention proposes a laser cutting device, which uses the battery shell processing fixture of the first aspect of the embodiment to fix the battery shell 100. The laser cutting device uses two manipulators to drive the laser cutting head to accurately cut the battery shell 100. During the processing, since the battery shell 100 is accurately fixed on the base 200 and the interior is fully supported, the battery shell 100 can be effectively prevented from being deformed. At the same time, due to the reasonable structural design of the internal support assembly 300, it can ensure that the battery shell 100 maintains a stable shape and size during the processing, thereby improving the processing accuracy.

[0047] The laser cutting equipment includes all the technical solutions of the battery shell processing fixture and has all the technical effects of the battery shell processing fixture, which will not be described here one by one.

[0048] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
