[0004] With the increasing demand for lithium batteries, it is particularly important to improve the production efficiency of lithium battery cells and reduce costs. Currently, the cover of blade batteries needs to be engraved with a QR code during the processing process, and after the QR code is engraved, it needs to be inspected.

[0005] During the process of cover engraving and inspection, the entire cover loading and transfer is usually carried out by a mechanical module. The cover is first positioned on the mechanical module, then the cover is fed to the engraving position by the mechanical module for engraving, and then transferred to the detector for inspection. Finally, the qualified cover is transported.

[0006] Mechanical modules suffer from poor transfer flexibility and require multiple positioning, handling, and assembly steps during each process, which is cumbersome. Positioning issues can affect laser engraving quality, and multiple handling can lead to machine damage. The multi-station turntable mechanism and control are complex.

[0043] To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0044] This embodiment relates to a battery cover plate processing device, in order to optimize the structure of the processing device and improve the processing efficiency of the battery cover plate 5.

[0045] The battery cover processing device comprises a sequentially arranged coding mechanism, a coding detection mechanism, a sorting mechanism, and a transfer mechanism. The coding mechanism is used to engrave patterns at preset locations on several cover plates 5, while the coding detection mechanism is used to detect whether the patterns are qualified. The sorting mechanism includes multiple placement sections for qualified products and for unqualified products. The qualified product placement section is used to place cover plates 5 with qualified coding, while the unqualified product placement section is used to place cover plates 5 with unqualified coding. The transfer mechanism is used to clamp each cover plate 5 and sequentially transfer them to the coding mechanism, coding detection mechanism, qualified product placement section, or unqualified product placement section.

[0046] The battery cover plate processing device described in this embodiment uses a transfer machine to clamp the cover plate 5 and transfer the cover plate 5 to the coding mechanism, the coding detection mechanism, the qualified product placement unit, or the unqualified product placement unit in sequence, which facilitates coding, coding detection, and classification of the cover plate 5. Compared with the traditional mechanical module method of transferring the cover plate 5, it helps reduce the number of positioning times of the cover plate 5 and has better transfer flexibility, thereby improving the processing efficiency of the cover plate 5. It also helps reduce the wear and tear of mechanical parts, thereby reducing production costs.

[0047] Based on the overall introduction above, an exemplary structure of the battery cover processing device described in this embodiment is shown in Figure 1. As a preferred embodiment, as shown in Figure 2, the transfer mechanism in this embodiment is a six-axis robotic arm 2 in the prior art, which is also called an industrial robot. The industrial robot is a multifunctional machine that can automatically control positioning and reprogram to change. The six-axis robotic arm 2 is mainly composed of three parts: a hand, a motion mechanism, and a control system. The hand is a component used to grasp the workpiece (or tool), and has various structural forms according to the shape, size, weight, material and operation requirements of the grasped object, such as clamping type, holding type, and adsorption type.

[0048] The kinematic mechanism of an industrial robot enables the hand to perform various rotations (swings), movements, or combined motions to achieve specified movements and change the position and posture of the grasped object. The independent motion modes of the kinematic mechanism, such as lifting, retracting, and rotating, are called the robot's degrees of freedom. The six-axis robotic arm 2 in this embodiment has six degrees of freedom. The control system of the six-axis robotic arm 2 completes specific movements by controlling the motors of each degree of freedom of the robot. At the same time, it receives feedback from external sensors to form a stable closed-loop control. The core of the control system is usually composed of a microcontroller chip such as a single-chip microcomputer, which is programmed to achieve the desired functions.

[0049] The transfer mechanism in this embodiment adopts a six-axis robotic arm 2, which can realize the free movement of the cover plate 5 in each processing station and has good movement flexibility. Compared with the existing technology that uses multiple mechanical modules to clamp and transfer the cover plate 5, it is conducive to reducing positioning operations and has the advantages of high transfer accuracy and efficiency.

[0050] To facilitate the gripping of the cover sheets 5, the transfer mechanism is equipped with several groups of grippers 302, each for gripping each cover sheet 5, and a first pneumatic cylinder for driving two grippers 302 in each group toward or away from each other. The two grippers 302 are driven toward or away from each other by the first pneumatic cylinder, facilitating the placement and placement of the cover sheets 5 and simplifying the arrangement and implementation.

[0051] As a preferred embodiment, the transfer mechanism is equipped with four sets of grippers 302 to simultaneously grip and transfer four cover plates 5. Of course, the number of grippers 302 on the transfer mechanism can be increased or decreased based on usage requirements, as long as the requirements are met. As shown in Figures 3 and 4, to facilitate the arrangement of the four sets of grippers 302, a mounting plate 3 is provided on the hand of the six-axis robot arm 2. The four sets of grippers 302 are spaced apart along the length of the mounting plate 3.

[0052] Two clamping jaws 302 in each set of clamping jaws 302 are mounted on a clamping jaw seat 304. The two clamping jaws 302 slide along the width of the mounting plate 3 on the clamping jaw seat 304. The aforementioned first air cylinder is also mounted on the clamping jaw seat 304. Driven by the first air cylinder, the two clamping jaws 302 can clamp the cover plate 5 along its thickness. Figure 3 illustrates the initial loading state of the cover plate 5. At this point, the outer side of the cover plate 5 faces upward, and the engraved area 300 to be engraved is located outside the clamping jaws 302.

[0053] In order to further improve the flexibility of use of the clamping jaws 302, the spacing between two adjacent groups of clamping jaws 302 in this embodiment is adjustable, so that different code engraving spacings and detection spacings can be adapted. Specifically, as shown in Figure 3, each clamping jaw seat 304 is slidably arranged on the guide rail 301 of the mounting seat along the length direction of the mounting plate 3. Second cylinders for driving each clamping jaw seat 304 to slide are also provided on the mounting plate 3. When it is necessary to adjust the spacing between the two groups of clamping jaws 302, the control system on the six-axis robot arm 2 sends a start-stop signal to each second cylinder, so that the spacing between the upper cover plates 5 of the two adjacent groups of clamping jaws 302 can be adjusted to the target spacing to meet the requirements of code engraving and code detection, as well as classified placement.

[0054] In addition, as shown in Figures 3 and 4 , a third detection unit 303 is provided on the gripper base 304 for detecting whether the cover plate 5 is present on the gripper 302. The third detection unit 303 can transmit detection information to the control system of the six-axis robotic arm 2. In a specific implementation, the third detection unit 303 can be a position sensor or other product with a position detection function.

[0055] The battery cover processing device in this embodiment is shown in Figure 1 and also includes a workbench 1. The aforementioned coding mechanism, coding detection mechanism, and classification mechanism are all disposed on the workbench 1, and the transfer mechanism is located on one side of the workbench 1. The coding mechanism in this embodiment includes a plurality of coding devices 6, each corresponding to a cover 5, and a dust cover 7 located between the coding devices 6 and the cover 5. The dust cover 7 is provided with a through hole 701 located along the coding path of each coding device 6. The cover 5 can abut against the dust cover 7, so that the coding area 300 of each cover 5 is exposed through the through hole 701.

[0056] Here, by setting up a number of code engravers 6 corresponding to the cover plate 5 one by one, the code area 300 on the cover plate 5 can be engraved at the same time, and the dust cover 7 and the through hole 701 thereon are used to collect impurities generated during the coding process, thereby reducing the pollution to the surrounding environment during the coding process.

[0057] In terms of specific structure, as shown in FIG5 , the engraving mechanism is also provided with four engravers 6 . To facilitate the installation of the engravers 6 , a mounting bracket 101 is provided on the workbench 1 . The four engravers 6 are spaced apart on the mounting bracket 101 along the length of the workbench 1 . The engravers 6 here can be laser engravers 6 as in the prior art. The pattern engraved by the engravers 6 in the engraving area 300 of the cover plate 5 can be a two-dimensional code to facilitate the acquisition of battery information. Of course, the specific shape and purpose of the pattern can be adjusted according to the needs of the user.

[0058] In this embodiment, the transfer mechanism drives the mounting plate 3 to rotate so that the coding area 300 of each cover plate 5 is set toward the dust cover 7, and the cover plate 5 is transferred to the coding station so that the coding area 300 of each cover plate 5 is set toward the corresponding coder 6. The dust cover 7 is located between the four coders 6 and the four cover plates 5. The bottom of the dust cover 7 is fixed on the workbench 1, and the top of the dust cover 7 is provided with an outlet for connecting to an external negative pressure device. The outer sides of the four cover plates 5 (mounted on the exposed side of the battery housing) are in contact with the dust cover 7, and the coding area 300 of each cover plate 5 is located in the through hole 701 and exposed to the through hole 701, so that the laser emitted by the coder 6 can enter through the through hole 701 and act on the coding area 300 of the cover plate 5 to complete the coding.

[0059] It should be noted that the number of code engravers 6 in this embodiment can be adaptively increased or decreased according to usage requirements. When the number of code engravers 6 is less than the number of cover plates 5, the code engraving on each cover plate 5 can be achieved by relative sliding of the mounting plate 3 and the code engraver 6.

[0060] The code detection mechanism in this embodiment includes at least one scanner and a controller 801 electrically connected to the scanner. The controller 801 is also electrically connected to the transfer mechanism. The controller 801 is configured to receive scanned information, compare the scanned information with preset information stored in the controller, and transmit the comparison result to the transfer mechanism. The sliding scanner facilitates scanning the pattern on the cover 5, and the controller 801 facilitates identification of whether the pattern is qualified.

[0061] The scanner here is a conventional barcode scanner 8, which can recognize a QR code and determine whether the QR code is qualified through a controller 801. Specifically, as a preferred embodiment, as shown in Figure 6, two barcode scanners 8 are spaced apart along the length of the workbench 1. After the code is engraved, the six-axis robot 2 simultaneously moves the four cover plates 5 onto the scanning path of the two barcode scanners 8, and adjusts the spacing between adjacent cover plates 5 to match the spacing between the two barcode scanners 8.

[0062] This arrangement enables the two barcode scanners 8 to simultaneously scan the QR codes on the two cover plates 5 on the left end of the mounting plate 3. By moving the six-axis robotic arm 2 to the left, the QR codes on the two cover plates 5 on the right side of the mounting plate 3 correspond to the two barcode scanners 8, and the QR codes on the two cover plates 5 are scanned separately. The barcode scanners 8 in this embodiment can achieve rapid code reading, thereby improving detection efficiency. Of course, the number of barcode scanners 8 can also be set to correspond one-to-one with the number of cover plates 5. In this case, the QR codes on the four cover plates 5 can be scanned and detected simultaneously, further improving detection efficiency.

[0063] In this embodiment, the controller 801 stores preset image information, also known as QR code information. If the image information (also known as the QR code information) transmitted by the barcode scanner 8 does not match the pre-stored information, the cover 5 is deemed unqualified for engraving. If the QR code information matches the pre-stored information, the cover 5 is deemed qualified for engraving. The controller 801 transmits the detection information to the control system of the six-axis robotic arm 2, which records the unqualified and qualified cover plates 5, thereby serving as a basis for classifying the cover plates 5.

[0064] As a preferred embodiment, as shown in Figures 7 and 8, the qualified product placement portion in this embodiment includes a plurality of first cover plate slots 401 slidably arranged along the arrangement direction of the multiple cover plates 5 in the transfer mechanism, and the unqualified product placement portion includes a plurality of second cover plate slots 402 spaced apart along the arrangement direction of the multiple cover plates 5 in the transfer mechanism, with the tops of the cover plates 5 exposed in the first cover plate slots 401 or the second cover plate slots 402, respectively. Here, the structures of the first cover plate slots 401 and the second cover plate slots 402 are simple and easy to arrange and implement. The fact that the cover plates 5 are exposed in the first cover plate slots 401 or the second cover plate slots 402 facilitates the removal and placement of the cover plates 5.

[0065] Specifically, as shown in Figures 1 and 7 , a sorting station 4 is located downstream of the code detection mechanism on the workbench 1. This station is positioned to one side of the six-axis robotic arm 2, facilitating the six-axis robotic arm 2's transfer of the covers 5 to either the first cover slot 401 or the second cover slot 402. In a preferred embodiment, the second cover slots 402 are arranged in multiple rows along the length of the workbench 1, each row containing four spaced-apart second cover slots 402.

[0066] The four second cover plate slots 402 correspond to the positions of the four clamped cover plates 5, ensuring that unqualified cover plates 5 can enter the second cover plate slots 402. The first cover plate slot 401 is arranged on the side of the sorting table 4 close to the six-axis robot arm 2. Both the first cover plate slot 401 and the second cover plate slot 402 extend along the length of the cover plate 5 to accommodate the horizontally arranged cover plates 5.

[0067] The first cover plate slot 401 is located closer to the six-axis robot arm 2 than the second cover plate slot 402. The number of first cover plate slots 401 can be two as shown in the figure. The two first cover plate slots 401 are slidably arranged on the sorting table 4. To drive the first cover plate slots 401 to slide separately, a third cylinder 405 for sliding each first cover plate slot 401 is provided on the sorting table 4. This facilitates changing the position of the first cover plate slots 401 to receive qualified cover plates 5.

[0068] In addition, to ensure that the cover plate 5 can be placed into the vacant first cover plate slot 401 or the second cover plate slot 402 after inspection, in this embodiment, a first inspection unit 404 for inspecting the cover plate 5 is provided on the first cover plate slot 401, and a second inspection unit 403 for inspecting the cover plate 5 is provided on the second cover plate slot 402. The first inspection unit 404 and the second inspection unit 403 are respectively electrically connected to the transfer mechanism. The first inspection unit 404 detects whether there is a cover plate 5 in the first cover plate slot 401, and the second inspection unit 403 detects whether there is a cover plate 5 in the second cover plate slot 402. The inspection information is transmitted to the transfer mechanism, which can guide the transfer mechanism to place the cover plate 5, so that the cover plate 5 is accurately placed into the vacant first cover plate slot 401 or the second cover plate slot 402.

[0069] As shown in Figure 7, both the first detection unit 404 and the second detection unit 403 can adopt position sensors in the existing technology. The first detection unit 404 is arranged on one side of the first cover plate groove 401, and can send a detection line to the other side of the first cover plate groove 401, so as to detect whether there is a cover plate 5 in the first cover plate groove 401, and send the detection information to the control system of the six-axis robot arm 2.

[0070] After the code engraving inspection is completed, if there is an unqualified cover plate 5 among the four cover plates 5, the six-axis robot arm 2 will move the four cover plates 5 to the top of a row of second cover plate slots 402 with unloaded second cover plate slots 402, and place the unqualified cover plate 5 corresponding to the unloaded second cover plate slots 402. Then, the clamping claws 302 will be driven to release the clamping of the unqualified cover plate 5, and the unqualified cover plate 5 will fall into the second cover plate slot 402. After all unqualified cover plates 5 are placed in the second cover plate slots 402 in this way, the qualified cover plates 5 will be moved to the top of the first cover plate slots 401.

[0071] The battery cover plate processing apparatus in this embodiment further includes a conveying mechanism located downstream of the sorting mechanism. The conveying mechanism is used to convey qualified cover plates 5. The transfer mechanism can transfer the qualified cover plates 5 from the placement section to the conveying mechanism. The provision of the conveying mechanism facilitates the conveying of qualified cover plates 5 and further improves the processing efficiency of the cover plates 5.

[0072] As a preferred embodiment, as shown in Figures 1 and 9, a conveying platform 102 is provided on the side of the classification table 4 away from the six-axis robot arm 2, which is perpendicular to the workbench 1, and the conveying mechanism is provided on the conveying platform 102. The conveying mechanism includes a magnetic levitation slide 103, and a base slidably arranged on the magnetic levitation slide 103, and a plurality of clamping discs 104 for clamping each cover plate 5 are provided on the base. In this embodiment, the number of clamping discs 104 is also four, so that four qualified cover plates 5 can be conveyed at the same time, thereby improving the conveying efficiency. Of course, the number of clamping discs 104 can also be adaptively increased or decreased according to usage requirements.

[0073] In this embodiment, the base slides on the magnetic levitation rails 103, providing high speed and stability, thereby improving the efficiency of conveying the cover 5. Testing has shown that the base can reach a maximum speed of 2 m / s with a load of 20 kg. Of course, in specific implementations, the conveying mechanism can also use other power methods to drive the base to slide, as long as it meets the requirements.

[0074] When the battery cover plate processing device of this embodiment is in use, the cover plates 5 are first loaded onto the clamping jaws 302. Specifically, the gripping end of the six-axis robot arm 2 is moved to the cover plate 5 loading position, and the four cover plates 5 are gripped and loaded by the clamping jaws 302. Next, the cover plates 5 are engraved. The mounting plate 3 is rotated to adjust the position of the cover plates 5, and the spacing between adjacent cover plates 5 is adjusted to correspond to the spacing between adjacent code engravers 6. The six-axis robot arm 2 simultaneously moves the four cover plates 5 to the code engraving station, so that the outer sides of the four cover plates 5 abut against one side of the dust hood 7. The external negative pressure portion draws the air inside the dust hood 7 outward, and the code engravers 6 start to engrave the QR code.

[0075] Then, the code engraving detection of the cover plate 5 is carried out, and the distance between the two cover plates 5 is adjusted to correspond to the distance between the two barcode scanners 8. The six-axis robot arm 2 moves the four cover plates 5 to the detection station, so that the two barcode scanners 8 first scan and detect the two cover plates 5 on the left, and send the detection information to the controller 801. The controller 801 sends the detection result to the control system, and then moves the mounting plate 3 through the six-axis robot arm 2, so that the two barcode scanners 8 scan and detect the two cover plates 5 on the right. The controller 801 sends the detection information to the control system of the six-axis robot arm 2, and the control system of the six-axis robot arm 2 marks whether the four cover plates 5 are qualified.

[0076] The covers 5 are then classified. The presence or absence of the covers 5 detected by the first detection unit 404 and the second detection unit 403 is sent to the control system of the six-axis robot 2. The control system of the six-axis robot 2 marks the positions of the empty first cover slot 401 and the second cover slot 402. The six-axis robot 2 then moves four covers 5 to the top of the empty second cover slot 402 and releases the grip on the unqualified covers 5, allowing the covers 5 to enter the second cover slot 402. The six-axis robot 2 then moves the remaining qualified covers 5 to the top of the empty first cover slot 401 and releases the grip on the qualified covers 5, allowing the covers 5 to enter the first cover slot 401.

[0077] Then, the qualified cover plates 5 are moved. When all the inspected cover plates 5 are qualified, the six-axis robot arm 2 directly transfers the four cover plates 5 to the loading position of the conveying mechanism and clamps and positions the four cover plates 5 on the clamping plate 104 for conveying. If some of the four inspected cover plates 5 are unqualified and some are qualified, the unqualified cover plates 5 are first placed in the second cover plate slot 402, and then the mounting plate 3 is moved above the first cover plate slot 401. The first cover plate slot 401 is slid so that the qualified cover plates 5 correspond to the clamping jaws 302 with the missing cover plates 5. At this time, the clamping jaws 302 with the missing cover plates 5 clamp the cover plates 5 until four cover plates 5 are clamped on the mounting plate 3. At this time, the six-axis robot arm 2 again transfers the four cover plates 5 to the loading position of the conveying mechanism. If all the inspected cover plates 5 are unqualified, each cover plate 5 is placed in the vacant second cover plate slot 402.
