In the relevant technology, during the production process of lithium batteries, laser marking equipment is usually used to engrave a QR code of specified specifications in the specified area of ​​the battery top cover to facilitate the traceability of product production information. Specifically, the engraving station of the battery top cover is determined. After the laser marking equipment is debugged in place, the QR code is engraved on each battery top cover that passes the engraving station continuously, and then the QR code is scanned and the information is entered in the next process.

[0003] At the coding station of the battery top cover, since the top cover is in a flat lying state with the coding surface facing downward, and due to the influence of the bottom processing space, the laser marking equipment cannot be installed under the coding surface, so the coding surface needs to be turned over to complete the engraving of the QR code on the battery top cover. If the top cover is directly turned over to expose the coding surface of the top cover, the top cover needs to be repeatedly positioned, and the positioning of the top cover is easily inaccurate during this process. In addition, the above method also increases the processing steps, thereby extending the production cycle. Utility Model Content

[0053] With the development of the new energy industry, lithium batteries are increasingly being used due to their many advantages such as multiple cycles, cyclic charging and discharging, and environmental friendliness. In the relevant technology, during the production process of lithium batteries, laser marking equipment is usually used to engrave a QR code of specified specifications in the specified area of ​​the battery top cover to facilitate the traceability of product production information. Specifically, the engraving station of the battery top cover is determined. After the laser marking equipment is debugged in place, the QR code is engraved on each battery top cover that passes the engraving station continuously, and then the QR code is scanned and the information is entered in the next process.

[0054] At the coding station of the battery top cover, since the top cover is in a flat lying state with the coding surface facing downward, and due to the influence of the bottom processing space, the laser marking equipment cannot be installed under the coding surface, so the coding surface needs to be turned over to complete the engraving of the QR code on the battery top cover. If the top cover is directly turned over to expose the coding surface of the top cover, the top cover needs to be repeatedly positioned, and the positioning of the top cover is easily inaccurate during this process. In addition, the above method also increases the processing steps, thereby extending the production cycle.

[0055] In order to solve the technical problem that the battery cover is not convenient to flip when engraving, refer to Figures 1 to 5An embodiment of the utility model provides a jig flipping mechanism, which is used to flip a workpiece positioned thereon, and the workpiece has a coding surface. For example, the workpiece can be a battery top cover, and the battery top cover has a coding surface. The jig flipping mechanism provided in this embodiment includes a base 100, a jig bottom plate 200 and a drive assembly 300. The base 100 provides a mounting and positioning foundation for the components of the entire jig flipping mechanism, the jig bottom plate 200 is used to receive the workpiece, and the drive assembly 300 is used to drive the jig bottom plate 200 to flip. Furthermore, the jig base plate 200 is connected to the base 100, and the jig base plate 200 is provided with a positioning wall 210 for positioning the workpiece. The jig base plate 200 is also provided with a through hole 220 penetrating the positioning wall 210. The jig base plate 200 is configured to enable the engraved surface of the workpiece to be exposed in the through hole 220. The driving component 300 is connected to the base 100, and is used to drive the jig base plate 200 to flip, wherein the driving component 300 is configured to drive the jig base plate 200 to flip so that the engraved surface exposed in the through hole 220 can be engraved by the laser component.

[0056] Specifically, in the present embodiment, a jig flipping mechanism is provided for conveniently flipping the code surface of a workpiece (for example, a battery top cover). At the coding station, when a two-dimensional code needs to be engraved on the code surface of the workpiece, the incoming workpiece is first fixedly positioned on the positioning wall 210 of the jig bottom plate 200 (for example, the workpiece can be clamped on the positioning wall 210 by a spring to ensure that the workpiece does not move on the positioning wall 210), and the code surface of the workpiece is aligned with the through hole 220 on the jig bottom plate 200, so that the code surface is exposed in the through hole 220, and the workpiece is ready to be fixed. After positioning, the driving component 300 is used to drive the jig base plate 200 to flip. For example, the jig base plate 200 can be driven to flip 90 degrees, 120 degrees, or 180 degrees. The flipping angle of the jig base plate 200 can be adaptively matched according to the position of the laser component. Since the workpiece is fixed on the jig base plate 200, the workpiece can be flipped by flipping the jig base plate 200, and the engraved surface of the workpiece can be exposed, so that the laser component can easily engrave a QR code on the engraved surface.

[0057] The jig flipping mechanism provided in this embodiment can be compatible with the state where the code surface faces down when the workpiece is received. The jig bottom plate 200 drives the workpiece to flip, and finally the code surface of the workpiece is exposed to the through hole 220, so as to facilitate the laser component to engrave the QR code on the code surface. In this way, the number of times the workpiece itself is flipped can be reduced, and repeated positioning of the workpiece can be avoided, thereby ensuring the positioning accuracy of the workpiece during coding, ensuring that the code position of the workpiece will not be offset, and ensuring the consistency of subsequent scanning and other processes. In this way, it is also possible to reduce processing steps, improve processing efficiency, and shorten the production cycle.

[0058] In some embodiments, the jig base plate 200 is connected to the base 100 through a rotating shaft, and a bearing is provided between the rotating shaft and the base 100. For example, the bearing may be a deep groove ball bearing. The driving assembly 300 may be connected only to the base 100 on one side of the jig base plate 200. Then, the side where the jig base plate 200 and the driving assembly 300 are connected is the main driving side, and the other side of the jig base plate 200 is the driven side. The main driving side drives the driven side to realize the flipping of the jig base plate 200. In this way, while satisfying the driving assembly 300 driving the jig base plate 200 to flip, it is helpful to simplify the overall structure of the jig flipping mechanism, save the space occupied by the jig flipping mechanism, and make the jig flipping mechanism tend to be miniaturized.

[0059] In some embodiments, reference Figures 1 to 4 The jig bottom plate 200 also includes a plurality of avoidance holes 230 arranged at intervals, and the avoidance holes 230 penetrate the positioning wall 210. By providing the avoidance holes 230 on the jig bottom plate 200, on the one hand, the weight of the jig bottom plate 200 can be reduced, and the flexibility of the jig bottom plate 200 can be improved when turning over. On the other hand, it is used to avoid batteries, improve the situation that some batteries interfere with the positioning mechanism during the process of coding a group of batteries in batches, and help improve the stability during the process of coding a group of batteries in batches.

[0060] In some embodiments, reference Figures 1 to 3 The driving assembly 300 includes a transmission part 310, and the transmission part 310 includes a guide rail 311, a swing arm 312 and a linkage block 313. One end of the swing arm 312 is connected to the base 100, and the swing arm 312 is provided with a first oblong hole 3121. One end of the linkage block 313 is slidably connected to the first oblong hole 3121, and the other end of the linkage block 313 is slidably connected to the guide rail 311, wherein the linkage block 313 is configured to be able to slide along the guide rail 311 and drive the swing arm 312 to swing, so as to realize the flipping of the fixture base plate 200.

[0061] Specifically, in this embodiment, a specific structure of a transmission part 310 is provided. During the flipping of the jig base plate 200, first, one end of the linkage block 313 makes a linear motion along the guide rail 311. At this time, the other end of the linkage block 313 slides in the first oblong hole 3121, and at the same time drives the swing arm 312 to start swinging. Driven by the swing arm 312, the jig base plate 200 can be flipped, so that the coding surface of the workpiece positioned on the jig base plate 200 is exposed from the through hole 220, so that the laser assembly can complete the coding on the coding surface. The transmission part 310 provided in this embodiment converts the linear motion of the linkage block 313 into the swinging motion of the swing arm 312, thereby driving the jig base plate 200 to flip.

[0062] In some embodiments, the linkage block 313 can be connected to the guide rail 311 through a slider, and the connection method is simple, the transmission is smooth and accurate, and the guide rail 311 provides a guide for the movement of the linkage block 313. The linkage block 313 can move linearly along the guide rail 311, reducing shaking and swaying in other directions to improve the stability of the linkage block 313 during movement. More preferably, in actual production, lubricant can be sprayed on the slider or the guide rail 311 to reduce the friction between the slider and the guide rail 311, improve the control accuracy between the slider and the guide rail 311, enhance the wear resistance of the slider and the guide rail 311, and extend the service life of the slider and the guide rail 311.

[0063] In some embodiments, reference Figures 1 to 3 The driving assembly 300 also includes a power unit 320, which includes a first cylinder 321 and a toggle unit 322. The toggle unit 322 is driven by the first cylinder 321. A toggle block 314 is provided at one end of the linkage block 313 close to the guide rail 311, wherein the toggle block 314 is connected to the toggle unit 322. The first cylinder 321 drives the toggle unit 322 to move, and the toggle unit 322 drives the linkage block 313 to slide along the guide rail 311 through the toggle block 314 connected thereto.

[0064] Specifically, in the present embodiment, a specific structure of a power unit 320 for driving the transmission unit 310 to move is provided. During the flipping process of the fixture base plate 200, the first cylinder 321 is first started, and the first cylinder 321 drives the toggle unit 322 to perform linear motion along the length direction X of the guide rail. Since the linkage block 313 is connected to the toggle unit 322 through the toggle block 314, the toggle unit 322 drives the linkage block 313 to slide along the guide rail 311, and then the linkage block 313 drives the swing arm 312 to start swinging. Driven by the swing arm 312, the fixture base plate 200 can be flipped at different angles.

[0065] In some embodiments, the first cylinder 321 can adopt a sliding cylinder, so that the power unit 320 can be installed in the space below the guide rail 311, which is convenient for the first cylinder 321 to drive the linkage block 313 to slide along the guide rail 311 through the cooperating toggle unit 322 and the toggle block 314, and is beneficial to reducing the overall footprint of the fixture flipping mechanism. At the same time, the sliding cylinder has high precision, which is beneficial to ensure the accuracy of the fixture base plate 200 when flipping.

[0066] Furthermore, position sensors may be provided at both ends of the guide rail 311 to protect the linkage block 313 from overtravel, thereby preventing the linkage block 313 from falling off the guide rail 311 due to overtravel, and avoiding damage to the mechanism. For example, the position sensor may be connected to a control system and an alarm system. When the linkage block 313 has a tendency to overtravel, the position signal may be transmitted to the control system. After receiving the signal, the control system may control the first cylinder 321 to stop urgently, thereby preventing the linkage block 313 from falling off the guide rail 311, and at the same time triggering an alarm to remind the worker to adjust the linkage block 313 to prevent damage before it occurs.

[0067] In some embodiments, reference Figures 1 to 3 The power unit 320 also includes a second cylinder 323, which is connected to the first cylinder 321 through a cylinder connecting plate 324. The shifting unit 322 is driven by the second cylinder 323 so that the shifting unit 322 can move toward or away from the shifting block 314.

[0068] Specifically, in the present embodiment, the shift block 314 and the shifting portion 322 are movably connected, for example, the shift block 314 and the shifting portion 322 can be snap-connected, so that the shifting portion 322 can be driven by the first cylinder 321 to move along the sliding direction of the linkage block 313, and can also be driven by the second cylinder 323 to move toward or away from the shift block 314. With such a structure, the connection accuracy between the shifting portion 322 and the shift block 314 can be adjusted at any time to ensure that the shifting portion 322 can drive the linkage block 313 to slide along the guide rail 311 through the shift block 314. For example, when the connection force between the shift block 314 and the shifting part 322 is too small, that is, the shift block 314 has not yet reached and contacted the bottom wall of the slot of the shifting part 322, the second cylinder 323 is activated, and the second cylinder 323 drives the shifting part 322 to move toward the shift block 314, so that the shifting part 322 and the shift block 314 are tightly connected, thereby ensuring the connection force between the shifting part 322 and the shift block 314. In addition, the active connection between the shift block 314 and the shifting part 322 also facilitates the assembly between the power part 320 and the transmission part 310, and reduces the difficulty of installing the fixture flipping mechanism.

[0069] In some embodiments, reference Figure 3 The shifting portion 322 is provided with a connecting groove 3221 , and the shifting block 314 is snap-connected to the connecting groove 3221 .

[0070] Specifically, in this embodiment, the shift block 314 can be a cam follower, and the size and diameter of the cam follower are adapted to the connection groove 3221, so that the cam follower can be snapped into the connection groove 3221, and then the shifting portion 322 can drive the linkage block 313 to slide along the guide rail 311 through the cam follower to achieve the flipping of the fixture bottom plate 200. Further, the connection groove 3221 can be designed as a U-shaped groove, and the curvature of the bottom wall of the U-shaped groove is consistent with the cam follower, so as to improve the connection stability of the cam follower in the U-shaped groove.

[0071] In some embodiments, reference Figures 4 to 5 The fixture flipping mechanism also includes a positioning card plate 400, which is arranged on the fixture flipping mechanism through an elastic part 410. Along the sliding direction of the linkage block 313, the positioning card plate 400 is provided with a first positioning card slot 420 and a second positioning card slot 430 at intervals. The linkage block 313 is provided with a positioning card block 315 at one end close to the guide rail 311, and the positioning card block 315 can be connected to the first positioning card slot 420 and the second positioning card slot 430. When the linkage block 313 slides along the guide rail 311, the positioning card block 315 can squeeze the elastic part 410, so that the positioning card block 315 moves from the first positioning card slot 420 to the second positioning card slot 430, so as to realize the positioning of the fixture bottom plate 200 before and after flipping.

[0072] Specifically, in the present embodiment, a structure is provided for positioning the jig base plate 200 before and after flipping, so as to keep the jig base plate 200 positioned in a horizontal state and a vertical state. For example, assuming that the jig base plate 200 is in a horizontal state, the positioning card block 315 is connected to the first positioning card slot 420, so that the linkage block 313 can be positioned on the guide rail 311, ensuring that the linkage block 313 will not move along the guide rail 311, and at the same time ensuring that the swing arm 312 will not swing, thereby ensuring the stability of the jig base plate 200 in a horizontal state. When the jig base plate 200 needs to be flipped from a horizontal state to a vertical state, the linkage block 313 is driven to move by the first cylinder 321 through the cooperating toggle portion 322 and the toggle block 314. During the movement of the linkage block 313, the positioning card block 315 will compress the spring to increase the positioning card The spacing between the block 315 and the positioning card plate 400 makes it easy for the positioning card block 315 to move out of the first positioning card slot 420. After the positioning card block 315 is moved out of the first positioning card slot 420, the positioning card block 315 will move along the edge of the positioning card plate 400 toward the second positioning card slot 430. At this time, the linkage block 313 will move along the guide rail 311 and drive the swing arm 312 to swing. The fixture base plate 200 is gradually flipping from a horizontal state to a vertical state. After the positioning card block 315 moves into the second positioning card slot 430, the fixture base plate 200 has been transformed into a vertical state, and the linkage block 313 is repositioned on the guide rail 311 to ensure that the linkage block 313 will not move along the guide rail 311, and at the same time ensure that the swing arm 312 will not continue to swing, thereby ensuring the stability of the fixture base plate 200 in the vertical state.

[0073] The positioning method of the jig base plate 200 provided in this embodiment is simple to operate and has a stable connection, and can realize a rapid transition of the jig base plate 200 between different states and can ensure the positioning stability of the jig base plate 200 in different states.

[0074] Further, refer to Figure 4 The shift block 314 and the positioning block 315 can be arranged on a connecting plate, and the connecting plate and the linkage block 313 are connected to one end close to the guide rail 311, which is conducive to improving the integration level of the mechanism and transforming the scattered single parts connection mode into an overall block connection mode.

[0075] In some embodiments, reference Figure 5The first positioning slot 420 includes a first arcuate slot wall 421 and a second arcuate slot wall 422, one end of the first arcuate slot wall 421 and one end of the second arcuate slot wall 422 are smoothly connected, and the second positioning slot 430 includes a third arcuate slot wall 431 and a fourth arcuate slot wall 432, one end of the third arcuate slot wall 431 and one end of the fourth arcuate slot wall 432 are smoothly connected. The opening of the first positioning slot 420 gradually increases from the connection side of the first arcuate slot wall 421 and the second arcuate slot wall 422 to the other side opposite thereto, and the opening of the second positioning slot 430 gradually increases from the connection side of the third arcuate slot wall 431 and the fourth arcuate slot wall 432 to the other side opposite thereto.

[0076] Specifically, in the present embodiment, a first positioning slot 420 and a second positioning slot 430 are provided as a structural form. In order to facilitate the positioning block 315 to move in or out of the first positioning slot 420 and the second positioning slot 430 and prevent the positioning block 315 from getting stuck in the first positioning slot 420 or the second positioning slot 430, thereby affecting the sensitivity of the fixture base plate 200 during the flipping process, the corner connections of the first positioning slot 420 and the second positioning slot 430 are both set to be rounded, that is, the groove walls of the first positioning slot 420 and the second positioning slot 430 are both in the form of smooth curves, which is conducive to improving the flexibility of the positioning block 315 during the movement process, thereby improving the sensitivity of the fixture base plate 200 during the flipping process.

[0077] Furthermore, the positioning block 315 may adopt a cam follower to replace sliding with rolling, thereby reducing the friction of the positioning block 315 during the movement process and improving the efficiency of the positioning block 315 during the movement process.

[0078] In some embodiments, reference Figures 4 to 5 The end of the elastic part 410 away from the first positioning slot 420 is connected to the adjusting part 440, and the adjusting part 440 is provided with a second oblong hole 441. An adjusting bolt is passed through the second oblong hole 441. The adjusting bolt is configured to be able to adjust the connection position of the adjusting part 440, so as to adjust the tightness of the elastic part 410.

[0079] Specifically, in this embodiment, by adjusting the position of the adjusting bolt in the second oblong hole 441, the position of the adjusting portion 440 can be adjusted, and then the length of the elastic portion 410 can be changed to ensure that a suitable elastic force is maintained between the positioning block 315 and the positioning plate 400, to prevent the elastic force between the positioning block 315 and the positioning plate 400 from being too loose, thereby causing the fixture base plate 200 to be unable to achieve stable positioning, or to prevent the elastic force between the positioning block 315 and the positioning plate 400 from being too tight, thereby causing the fixture base plate 200 to be unable to be flexibly flipped.

[0080] In some embodiments, reference Figures 1 to 3 The base 100 is provided with an oil pressure buffer 110 , which is connected to the base 100 through a connecting seat and is used to buffer power during the flipping process of the fixture bottom plate 200 .

[0081] Specifically, in this embodiment, the large impact force generated by the jig base plate 200 during the flipping process can be consumed and buffered by the oil pressure buffer 110, thereby ensuring the stability of the jig base plate 200 during the flipping process.

[0082] It should be noted that the oil pressure buffer 110 is a commonly used device in the art, so its structure and operation process are not described in detail.

[0083] Correspondingly, another embodiment of the present invention further provides a battery production device, which includes the jig flipping mechanism in any of the above embodiments.

[0084] In this embodiment, specifically, the battery production device can be a lithium battery production device. The battery production device using the above-mentioned jig flipping mechanism is conducive to ensuring the accuracy of the battery during the production process, improving the efficiency of the battery during the production process, and optimizing the compatibility between various mechanisms in the battery production device.

[0085] Thanks to the improvement of the above-mentioned jig flipping mechanism, the battery production device of this embodiment has the same technical effect as the above-mentioned jig flipping mechanism, which will not be described in detail here.

[0086] It should be noted that the other contents of the jig flipping mechanism and the battery production device disclosed in the present utility model can be referred to the prior art and will not be described in detail here.
