Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] At present, after the production of battery cells is completed, laser marking equipment is usually used to mark different defects on the battery in order to trace the various production processes of the battery cells. However, this laser marking method melts or vaporizes the surface material on the battery cell at high temperature to reveal a specific shape. This marking process not only has high protection and dust removal requirements for the use of lasers, but also reduces the active materials on the battery cell and reduces the battery capacity.
[0039] The utility model provides a code engraving device.
[0040] See also Figure 1 and Figure 2 In one embodiment of the present invention, the coding device 100 comprises:
[0041] Control systems;
[0042] A feature recognition mechanism 1 is connected to the control system for recognizing target features on the target product 10; and
[0043] The mechanical coding mechanism 2 is arranged on one side of the feature recognition mechanism 1. The mechanical coding mechanism 2 is connected to the feature recognition mechanism 1 through a control system communication. The mechanical coding mechanism 2 is used to mechanically engrave an identification pattern 220 on the target product 10, and the identification pattern 220 is adapted to the target feature.
[0044] In the technical solution of the utility model, after the target product 10 completes the processing of each production process, it needs to be inspected; the feature recognition mechanism 1 in this solution is used to identify the target features on the target product 10, and feed back the detected target feature information to the communication system, and the mechanical coding mechanism 2 will be connected to the feature recognition mechanism 1 through the communication system, so that the mechanical coding mechanism 2 mechanically engraves the corresponding identification pattern 220 on the target product 10 according to the provided target feature information, and the identification pattern 220 matches the target feature, which is conducive to classifying and marking multiple target features on the target product 10, and facilitating the timely identification and inspection of the target product 10 when problems occur during subsequent use. In this solution, the marking of the target features is mechanically engraved. Compared with the high-risk source laser coding, this mechanical coding method is safer and more convenient, and can protect the active materials on the electric chip and ensure the performance of the battery.
[0045] Specifically, the coding device 100 provided in this solution can be applied not only to the production traceability of electric chips, but also to the production traceability of many other different materials, such as copper foil, aluminum foil, wood or steel products, and is compatible with different products to be coded. The feature recognition mechanism 1 can be a CCD detection device, or an infrared sensor, etc., as long as it can distinguish multiple different features on the target product 10. It should be noted that the mechanical coding mechanism 2 in this solution can engrave and press out a matching identification pattern 220 according to different target features. Taking the electric chip as an example, when it is detected, target features such as black spots, white spots, lithium deposition or burr edges may appear. Accordingly, the mechanical coding mechanism 2 will specifically engrave different shapes of identification patterns 220 for each target feature. For example, the identification pattern 220 can have information such as a circle, a triangle, a hexagon, a barcode or a two-dimensional code. As long as the multiple target features that need to be marked are individually provided with a matching identification pattern 220, the classification of target products 10 containing different target features can be achieved. It should be noted that the coding device 100 can be applied not only to marking different target features on the same material, but also to marking a variety of different materials to classify them at the same time, thereby recording information of different types of products. In addition, the control system in this solution can be a PLC or a CPU or other module.
[0046] In one embodiment of the present invention, please refer to Figures 4 to 6 , the mechanical coding mechanism 2 comprises:
[0047] A mounting base 21 movably disposed above the target product 10 to move closer to or away from the target product 10; and
[0048] The code engraver 22 is rotatably disposed on the mounting base 21 , and a plurality of different identification patterns 220 are arranged at intervals on the code engraver 22 .
[0049] Specifically, in order to smoothly complete the coding action on the target product 10, the present embodiment has a mounting seat 21 movably arranged above the target product 10, and the code engraver 22 is rotatably mounted on the mounting seat 21; when the feature recognition mechanism 1 recognizes that the target product 10 has certain target features that need to be marked, the mounting seat 21 is controlled by the control system to move close to the target product 10, and the code engraver 22 is driven by the mounting seat 21 to gradually approach the target product 10 until it abuts against the target product 10 to complete the coding; after the coding is completed, the mounting seat 21 drives the code engraver 22 to move away from the target product 10, and then the target product 10 is driven to the subsequent detection process.
[0050] In one embodiment of the present invention, please refer to Figure 4 When the target product 10 is a continuous coil, the coder 22 includes an engraving roller, which is rotatably arranged on the mounting seat 21, and a plurality of different identification patterns 220 are arranged at intervals on the outer circumference of the engraving roller; the target product 10 first undergoes a pre-processing process and is placed under the mechanical engraving mechanism 2 to be coded. After the feature recognition mechanism 1 in this embodiment completes the recognition of the target product 10, the engraving roller is rotated so that the identification pattern 220 matching the target feature is aligned with the target product 10. At this time, the mounting seat 21 moves close to the target product 10 until it contacts the target product 10, and begins to engrave the identification pattern 220; since the target product 10 is a continuous coil, the target product 10 will continue to move with the conveying mechanism 5. During the coding process, the engraving roller will correspondingly follow the target product 10 to rotate a certain angle until the identification pattern 220 is completely engraved. It should be noted that before the coding action is performed, the rotation angle of the engraving roller during the coding process of each identification pattern 220 is counted and transmitted to the control system. The control system positions the rotation angle and controls the mounting base 21 to move away from the target product 10 after a complete identification image is pressed.
[0051] In one embodiment of the present invention, please refer to Figure 5 and Figure 6When the target product 10 is an intermittent sheet, the code engraver 22 includes a pressing plate, which is rotatably arranged on the mounting seat 21, and a plurality of different identification patterns 220 are arranged at intervals on the side of the pressing plate facing the target product 10; the target product 10 first undergoes a pre-processing process and is placed under the mechanical coding mechanism 2 to be coded. After the feature recognition mechanism 1 in this embodiment completes the recognition of the target product 10, the target product 10 stays under the code engraver 22, and the identification pattern 220 matching the target feature is aligned with the target product 10 by rotating the pressing plate. At this time, the mounting seat 21 moves close to the target product 10 until it contacts it, and starts to press down and engrave the identification pattern 220, and after pressing out a complete identification image, the mounting seat 21 is controlled to move away from the target product 10 to complete the coding process.
[0052] In one embodiment of the present invention, please refer to Figures 4 to 6 The mechanical coding mechanism 2 also includes a base frame 23, which is arranged above the target product 10, and the mounting seat 21 is slidably arranged on the base frame 23. For example, a slide rail for the mounting seat 21 to slide can be provided on the base frame 23, so that the mounting seat 21 can reciprocate along the width direction of the target product 10; in this way, the code engraver 22 slides in the width direction of the target product 10 under the action of the mounting seat 21, and different target features in the width direction of the target product 10 can be marked, and the marking range is wider.
[0053] In one embodiment of the present invention, please refer to Figures 4 to 6 The mechanical coding mechanism 2 also includes a lifting member 24, a fixed end of the lifting member 24 is arranged on the base frame 23, and the lifting end of the lifting member 24 is fixedly connected to the mounting seat 21 to drive the mounting seat 21 to move closer to or away from the target product 10; the setting of the lifting member 24 facilitates the mounting seat 21 to achieve up and down lifting. It should be noted that the lifting member 24 can be a lifting cylinder, or a motor-driven screw rod, gear rack, or an electric cylinder, etc., as long as it can play the role of driving the mounting seat 21 to rise and fall.
[0054] In one embodiment of the present invention, please refer to Figures 4 to 6 In order to facilitate the rotation of the encoder 22, the mechanical engraving mechanism 2 also includes a driving member 25, which is mounted on the mounting seat 21 and is connected to the encoder 22 to drive the rotation of the encoder 22; when the target product 10 moves to the bottom of the encoder 22, the encoder 22 needs to be rotated so that the identification image corresponding to the target feature on the encoder 22 is aligned with the target product 10. It should be noted that the driving member 25 can be an output shaft disk, a hollow rotating platform, a rotating cylinder connected to the encoder 22, or a servo motor drives a synchronous belt or gear to rotate, thereby driving the encoder 22 to rotate, etc., as long as it can play the role of driving the encoder 22 to rotate.
[0055] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 The coding device 100 also includes a cleaning mechanism 3, which is arranged at one side of the mechanical coding mechanism 2 and is used to clean the target product 10 that has been coded. In this way, the cleaning mechanism 3 can clean the residual debris generated by the coding on the surface of the target product 10. It should be noted that the cleaning mechanism 3 can be a cleaning brush, which uses multiple cleaning hairs on the brush to sweep away the debris; it can also be a wind knife, which is mainly composed of a wind knife blade and a wind nozzle, wherein the wind knife blade plays a role in guiding the flow, and different numbers of blades and the inclination angle of the blades can be replaced according to different needs to achieve different cleaning effects. The role of the wind nozzle is to change the direction of the wind to a certain extent, and the opening angle of the wind nozzle can be adjusted accordingly according to actual needs.
[0056] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 In order to detect the target product 10 after coding and avoid the problem that the identification pattern 220 is inconsistent with the target feature, the coding device 100 also includes a scanning mechanism 4, which is arranged at a distance from the cleaning mechanism 3 on the side away from the mechanical coding mechanism 2 to detect the identification pattern 220 on the target product 10 after coding. The setting of the scanning mechanism 4 can check whether there is any wrong identification pattern 220 and whether the identification pattern 220 is completely engraved, so as to ensure the realization of the later traceability function. The scanning mechanism 4 can be an industrial camera or other image recognition structures.
[0057] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 The coding device 100 further includes a conveying mechanism 5, which is used to convey the target product 10 to the mechanical coding mechanism 2. The target product 10 can be conveyed to the mechanical coding mechanism 2 through the conveying mechanism 5 and output after the coding is completed. The conveying mechanism 5 is usually a combination of a rolling roller and a conveyor belt. In order to tighten or loosen the conveyor belt, the coding device 100 further includes a tension adjustment mechanism 6, which is connected to the conveying mechanism 5 and is used to adjust the tension of the conveying mechanism 5. For example, the tension adjustment mechanism 6 may include a tension adjustment component and a tension detection roller provided on the conveyor belt, wherein the tension adjustment component controls the tension of the conveyor belt, and the tension detection roller detects the change in tension.
[0058] In one embodiment of the present invention, please refer to Figure 1 and Figure 2The conveying mechanism 5 includes a main driving mechanism 7, which is connected to the conveying mechanism 5 to drive the movement of the conveying mechanism 5. The setting of the main driving mechanism 7 can drive the conveyor belt to rotate, and can also form a closed-loop control with the tension adjustment mechanism 6 to ensure the speed and accuracy of the conveyor belt. The main driving mechanism 7 can be a driving device such as a servo motor.
[0059] In one embodiment of the present invention, please refer to Figure 2 The coding device 100 further includes a cutting mechanism 8, which is arranged at a distance on one side of the mechanical coding mechanism 2, and has a tendency to move closer to or away from the target product 10 to cut the target product 10 according to the target size. For the target product 10 that is a continuous roll material in the early stage and needs to be coded in an intermittent sheet material in the later stage, the cutting mechanism 8 can cut it according to the target size before the target product 10 reaches the bottom of the coding device 22. It can be understood that the cutting mechanism 8 includes a manipulator and a cutting blade, so that the cutting blade can cut the target product 10 in any direction under the action of the manipulator.
[0060] In one embodiment of the present invention, please refer to Figure 1 and Figure 2 In order to improve the coding efficiency, it is ensured that the target product 10 accurately reaches the bottom of the code engraver 22 before starting the coding action. The coding device 100 includes a positioning detection mechanism 9, which is in communication with the control system and is used to detect whether the target product 10 reaches the bottom of the mechanical coding mechanism 2. The positioning detection mechanism 9 can be an encoding roller provided with an encoder, which can detect the conveyor belt speed and accuracy, so that the target product 10 can be accurately detected to be located under the mechanical coding mechanism 2 before coding, avoiding the situation where there is no target product 10 and the coding is empty or the coding position is inaccurate. In addition, the encoder can form a closed-loop control with the main drive mechanism 7 to ensure the accuracy of the conveyor belt speed and accuracy during the coding process, thereby ensuring that the identification pattern 220 can be accurately engraved at the target position.
