Technical Field

[0001] This application relates to the field of battery manufacturing technology, and more specifically, to a coding device. Background Technology

[0002] During battery manufacturing, QR codes need to be sprayed or laser-engraved on the surface of individual battery cells to facilitate subsequent process traceability, quality control, inventory management, anti-counterfeiting, and after-sales warranty. As a core component of lithium battery manufacturing and digital management, QR code spraying is integrated throughout the entire lifecycle of each battery cell, improving not only the quality, efficiency, and safety of automated manufacturing but also meeting regulatory and commercial requirements.

When the rocker arm abuts against the first transition surface, the battery cell held by the upper gripper is adjusted from a vertical state to a horizontal state. When the rocker arm abuts against the spraying guide surface, the battery cell held by the upper gripper remains in a horizontal state. The coding device is configured to correspond to the extension range of the spraying guide surface.

[0009] Optionally, the guide further includes a second transition surface, wherein the first transition surface, the spraying guide surface and the second transition surface are connected in sequence, and when the rocker arm abuts against the second transition surface, the battery cell held by the upper gripper is adjusted from a horizontal state to a vertical state.

[0010] Optionally, the rocker arm is provided with rollers, which are configured to cooperate with the guide.

[0011] Optionally, the cup separation device includes: a first cam turntable; a plurality of first clamping units circumferentially spaced on the first cam turntable, each first clamping unit including a first jaw and a second jaw, the first jaw and the second jaw being spaced apart, the first jaw being used to clamp a battery cell, the second jaw being used to clamp a cup, and the second jaw being able to move away from the first jaw to drive the cup to separate from the battery cell.

Detailed Implementation

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0031] Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely to illustrate selected embodiments of the application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0032] like Figure 1As shown, the coding device 100 of this application embodiment includes a cup separation device 110, a conveying device 120, a coding device 130, and a cup merging device 140. The cup separation device 110 is used to separate the cup 220 from the battery cell 210; the conveying device 120 is disposed downstream of the cup separation device 110 and is used to receive and convey the battery cell 210 and the cup 220; the coding device 130 is used to spray a QR code onto the battery cell 210 conveyed on the conveying device 120; the cup merging device 140 is disposed downstream of the conveying device 120 and is used to receive the battery cell 210 and the cup 220 and assemble the battery cell 210 with the cup 220.

[0033] The coding device 100 of this application embodiment can receive an assembly 200 in which battery cells 210 and cup holders 220 are assembled together. The cup holder 220 is automatically separated from the battery cell 210 via a cup separation device 110. Both the battery cell 210 and the cup holder 220 are synchronously conveyed into a conveying device 120. The coding device 130 sprays QR codes onto the battery cells 210 on the conveying device 120. After coding, both the battery cell 210 and the cup holder 220 enter a cup merging device 140, where they are automatically assembled to form the integrated assembly 200. Because the separation and assembly of the cup holder 220 are completed automatically, the time and manpower required for this process are reduced, improving operational safety and overall coding efficiency for the battery cells 210.

[0034] like Figure 2 , Figure 3 and Figure 4 As shown, in some embodiments of this application, the conveying device 120 includes a conveying mechanism 121 and a plurality of inkjet printing fixtures 122. The plurality of inkjet printing fixtures 122 are spaced apart from each other on the conveying mechanism 121. The conveying mechanism 121 is used to drive the plurality of inkjet printing fixtures 122 to move. The inkjet printing fixture 122 includes a fixture support 1221, an upper gripper 1222 and a lower gripper 1223. The upper gripper 1222 and the lower gripper 1223 are spaced apart from each other on the fixture support 1221. The upper gripper 1222 is used to hold the battery cell 210 and the lower gripper 1223 is used to hold the cup 220.

[0035] The conveying mechanism 121 conveys the coding fixture 122 along the first direction X. The cup separation device 110 and the cup merging device 140 are respectively disposed at both ends of the conveying mechanism 121 along the first direction X. The upper gripper 1222 and the lower gripper 1223 are both magnetic grippers or negative pressure suction cup grippers. The upper gripper 1222 is disposed above the lower gripper 1223 along the vertical direction Z. The fixture support 1221 drives the upper gripper 1222 and the lower gripper 1223 to move synchronously.

[0036] With this configuration, the battery cell 210 and the corresponding cup 220 can be transported simultaneously. The cup 220 separated at the cup separation device 110 can be transported to the cup merging device 140. The cup 220 corresponds one-to-one with the battery cell 210, which improves the transfer efficiency of the cup 220.

[0037] In some embodiments of this application, the conveying mechanism 121 is a ring-shaped conveying mechanism, and the coding device 130 is arranged on one side of the conveying mechanism 121 along the second direction Y. Multiple coding fixtures 122 drive the battery cells 210 through the coding device 130 and perform coding operations. After the battery cells 210 and the corresponding cups 220 are unloaded into the cup merging device 140, the coding fixture 122 moves from the other side of the conveying mechanism 121 along the second direction Y to the unloading position of the cup separating device 110 in an unloaded state to receive the next batch of battery cells 210 and cups 220.

[0038] With this configuration, battery cells 210 and cups 220 can be continuously received from the cup separation device 110. After the coding operation is completed, the battery cells 210 and cups 220 are unloaded into the cup merging device 140, realizing cyclic operation and improving coding efficiency.

[0039] like Figure 5 and Figure 6 As shown, in some embodiments of this application, the upper gripper 1222 is rotatably disposed on the fixture bracket 1221, the inkjet fixture 122 further includes a rocker arm 1224, the conveying device 120 further includes a guide 123, the guide 123 is disposed on the conveying mechanism 121, one end of the rocker arm 1224 is connected to the upper gripper 1222, and the other end abuts against the guide 123.

[0040] It is understandable that the battery cell 210 received by the conveying device 120 is in a vertical position. It is necessary to adjust the battery cell 210 to a horizontal position before spraying the QR code onto it, which can improve the quality of the coding.

[0041] The upper gripper 1222 has a connecting shaft on its back side. The rocker arm 1224 includes a first end 1225 and a second end 1226. The first end 1225 is connected to the connecting part, and the second end 1226 is in sliding or rolling engagement with the guide member 123. The guide member 123 extends along the first direction X in its length direction and is disposed inside the conveying mechanism 121. One side of the guide member 123 along the vertical direction Z is used to engage with the second end 1226 of the rocker arm 1224.

[0042] With this configuration, a guide 123 cooperates with multiple coding jigs 122, resulting in a simple structure and the ability to precisely adjust the state of the upper gripper 1222.

[0043] In other embodiments, each coding fixture 122 may also be independently equipped with a rotation drive, and each upper gripper 1222 rotates under the corresponding rotation drive.

[0044] like Figure 5 As shown, in some embodiments of this application, the guide 123 includes a first transition surface 1231 and a spraying guide surface 1232 connected in sequence. When the rocker arm 1224 abuts against the first transition surface 1231, the battery cell 210 held by the upper gripper 1222 is adjusted from a vertical state to a horizontal state. When the rocker arm 1224 abuts against the spraying guide surface 1232, the battery cell 210 held by the upper gripper 1222 remains in a horizontal state. The marking device 130 is correspondingly set with the extension range of the spraying guide surface 1232.

[0045] The first transition surface 1231 and the spraying guide surface 1232 are connected sequentially along the conveying direction (i.e., the first direction X) of the conveying mechanism 121. The second end 1226 of each rocker arm 1224 passes sequentially through the first transition surface 1231 and the spraying guide surface 1232. During the passage of the second end 1226 of the rocker arm 1224 through the first transition surface 1231, the battery cell 210 is adjusted from a vertical state to a horizontal state. During the passage of the spraying guide surface 1232, the battery cell 210 remains in a horizontal state. Within the range extended along the first direction X by the spraying guide surface 1232, the coding device 130 completes the spraying and coding detection processes on the battery cell 210 that is maintained in a horizontal state.

[0046] With this configuration, the upper gripper 1222 can drive the battery cell 210 to rotate. The first transition surface 1231 guides the upper gripper 1222 to gradually rotate to a horizontal state, reducing the shaking of the battery cell 210 during rotation and thus improving the coding quality.

[0047] like Figure 5 As shown, in some embodiments of this application, the guide 123 further includes a second transition surface 1233. The first transition surface 1231, the spraying guide surface 1232, and the second transition surface 1233 are sequentially connected along the conveying direction (i.e., the first direction X) of the conveying mechanism 121. During the process of passing through the second transition surface 1233, the second end 1226 of the rocker arm 1224 adjusts the battery cell 210 from a horizontal state to a vertical state.

[0048] With this configuration, the battery cell 210 can be reset to a vertical position so that it can dock with the cup merging device 140.

[0049] like Figure 6 As shown, in some embodiments of this application, the rocker arm 1224 is provided with a roller 1227, which is configured to cooperate with the guide 123.

[0050] Roller 1227 is disposed at the second end 1226 of rocker arm 1224, and roller 1227 rolls in cooperation with the first transition surface 1231, the spraying guide surface 1232 and the second transition surface 1233 of guide member 123.

[0051] This configuration reduces the wear on the rocker arm 1224 and the guide member 123, thereby increasing the effective lifespan of the conveying device 120.

[0052] like Figure 2 As shown, in some embodiments of this application, the coding device 130 includes a coding mechanism 131 and a scanning detection mechanism 132. The coding mechanism 131 is used to spray QR codes onto the battery cells 210 conveyed on the conveying device 120; the scanning detection mechanism 132 is disposed downstream of the coding mechanism 131 and is used to read the QR codes on the battery cells 210 to detect the coding quality of the QR codes.

[0053] The inkjet printing mechanism 131 and the barcode scanning and detection mechanism 132 are arranged at intervals along the first direction X and are both located within the extension range of the spraying guide surface 1232. Each battery cell 210 passes through the inkjet printing mechanism 131 and the barcode scanning and detection mechanism 132 in sequence and is gradually adjusted to a vertical state. Two inkjet printing mechanisms 131 are provided as backup devices or to adapt to different rhythms.

[0054] This setup allows for efficient and reliable application of QR codes to horizontally positioned battery cells 210, completing the coding operation.

[0055] like Figure 7 , Figure 8 and Figure 9 As shown, in some embodiments of this application, the cup separation device 110 includes a first cam turntable 111 and a plurality of first clamping units 112. The plurality of first clamping units 112 are circumferentially spaced on the first cam turntable 111. Each first clamping unit 112 includes a first clamping jaw 113 and a second clamping jaw 114. The first clamping jaw 113 and the second clamping jaw 114 are spaced apart. The first clamping jaw 113 is used to clamp the battery cell 210, and the second clamping jaw 114 is used to clamp the cup 220. The second clamping jaw 114 can move away from the first clamping jaw 113 to drive the cup 220 to separate from the battery cell 210.

[0056] The first cam turntable 111 has an axial direction of a first axis P, which is parallel to the vertical direction Z. The first cam turntable 111 also includes a first groove 1111 and a second groove 1112 spaced apart along the first axis P. The first gripper 113 includes a peripheral gripping portion 1131 and a first support 1133. The peripheral gripping portion 1131 is fixed to the first support 1133, and the first support 1133 is mounted on the first groove 1111. The second gripper 114 is mounted on the second groove 1112. The first gripper 113 and the second gripper 114 are spaced apart along the axial direction of the first cam turntable 111. A portion of the second groove 1112 extends away from the first groove 1111 to move the second gripper 114 away from the first gripper 113. The second gripper 114 grips the cup 220 away from the battery cell 210, thus separating the cup 220 from the battery cell 210.

[0057] With this configuration, the second gripper 114 can be easily and reliably moved closer to or away from the first gripper 113, thereby separating the cup 220 from the battery cell 210.

[0058] In other embodiments, the second gripper 114 can be driven away from the first gripper 113 in other ways, and the second gripper 114 can also move away from the first gripper 113 in other directions.

[0059] like Figure 8 and Figure 9 As shown, in some embodiments of this application, the first gripper 113 includes a peripheral gripping portion 1131 and a top gripping portion 1132. The peripheral gripping portion 1131 is used to grip the battery cell 210 circumferentially, and the top gripping portion 1132 is used to grip the top side of the battery cell 210. The top gripping portion 1132 is disposed on the side of the peripheral gripping portion 1131 away from the second gripper 114. The top gripping portion 1132 can move away from the peripheral gripping portion 1131 to adjust the height position of the battery cell 210.

[0060] Both the peripheral clamping part 1131 and the top clamping part 1132 are magnetic clamps or negative pressure suction cup clamps. The top clamping part 1132 is arranged along the first axis P on the side of the peripheral clamping part 1131 away from the second clamp 114. The top clamping part 1132 can drive the battery cell 210 to move up and down along the axis of the first cam turntable 111 to adjust the height position of the battery cell 210.

[0061] Specifically, the first cam turntable 111 further includes a third slide groove 1113, which is spaced apart from the first slide groove 1111 along the first axis P and is located on the side of the first slide groove 1111 away from the second slide groove 1112. The first gripper 113 also includes a second bracket 1134, which is slidably mounted on the first bracket 1133 along the first axis P. The top-side clamping portion 1132 is fixed to the second bracket 1134, and the second bracket 1134 is mounted on the third slide groove 1113. The third slide groove 1113 extends in a direction away from the first slide groove 1111 to drive the top-side clamping portion 1132 away from the second gripper 114.

[0062] It is understandable that when the peripheral clamping part 1131 and the top clamping part 1132 are fixed in a relatively fixed position, they jointly adsorb and clamp the battery cell 210; when the top clamping part 1132 drives the battery cell 210 to move upward, the peripheral clamping part 1131 releases the periphery of the battery cell 210.

[0063] The cup separation device 110 also includes an arc-shaped support plate, which is arranged circumferentially around the first cam turntable 111 and is located on the part of the top clamping part 1132 that drives the battery cell 210 to adjust its height position, so as to support the bottom of the battery cell 210.

[0064] With this configuration, the height of the battery cell 210 can be adjusted so that it corresponds to the feeding height of the conveying device 120.

[0065] In other embodiments, the peripheral clamping part 1131 and the second clamping claw 114 may be installed in the same slide groove, and the top clamping part 1132 may be installed in another slide groove. The top clamping part 1132 drives the battery cell 210 to rise, and the second clamping claw 114 drives the cup 220 to fall, thereby realizing the separation of the battery cell 210 and the cup 220.

[0066] In some embodiments of this application, the first axis P extends along the vertical direction Z, and the first gripper 113 is disposed on the upper side of the second gripper 114; in other embodiments, the first axis P may also extend along other directions.

[0067] In some embodiments of this application, the cup separation device 110 further includes a first sensing component 115, which is disposed on the periphery of the first cam turntable 111. The first sensing component 115 is disposed at the unloading point of the first cam turntable 111 and is used to detect whether the battery cell 210 has fallen off.

[0068] For example, the first sensing component 115 is a through-beam sensor that detects in real time whether the laser at the height position corresponding to the first gripper 113 of each first clamping unit 112 is blocked. If the receiver can receive the laser, it is determined that the battery cell 210 of the first clamping unit 112 has fallen.

[0069] This configuration improves the reliability of the cup separation device 110 and the coding device 100.

[0070] In some embodiments of this application, the cup merging device 140 includes a second cam turntable 141 and a plurality of second clamping units 142. The plurality of second clamping units 142 are circumferentially spaced on the second cam turntable 141. Each second clamping unit 142 includes a third clamping jaw 143 and a fourth clamping jaw. The third clamping jaw 143 is used to clamp the battery cell 210, and the fourth clamping jaw is used to clamp the cup 220. The fourth clamping jaw can move toward the third clamping jaw 143 to assemble the battery cell 210 and the cup 220.

[0071] Similar to the construction of the cup separation device 110, the second cam turntable 141 includes a fourth slide groove and a fifth slide groove spaced apart along its axial direction. The third gripper 143 is mounted on the fourth slide groove, and the fourth gripper is mounted on the fifth slide groove. The fifth slide groove extends towards the fourth slide groove. The fourth gripper is configured to move along the trajectory of the fifth slide groove and approach the third gripper 143, thereby driving the cup 220 to approach the battery cell 210 to assemble the battery cell 210 with the cup 220.

[0072] With this configuration, the fourth gripper of each second clamping unit 142 can be moved easily and reliably, so as to assemble the cup holder 220 with the battery cell 210.

[0073] In other embodiments, multiple second clamping units 142 can be transported by other conveying devices; the fourth gripper can also move closer to or further away from the third gripper 143 in other directions; the battery cell 210 can also be released by the third gripper 143 and fall into the cup 220 to achieve the assembly of the two.

[0074] In some embodiments of this application, the conveying device 120 further includes a second sensing component 124, and the cup merging device 140 further includes a third sensing component 145. The second sensing component 124 is disposed at the unloading point of the conveying mechanism 121 and is used to detect whether each coding fixture 122 clamps the battery cell 210 and the cup 220. The third sensing component 145 is disposed at the unloading point of the second cam turntable 141 and is used to detect whether the battery cell 210 of each second clamping unit 142 has fallen into the cup 220.

[0075] In some embodiments of this application, the coding device 100 further includes a rejection device 150, which is located downstream of the cup merging device 140, for rejecting unqualified battery cells 210.

[0076] The rejection device 150 includes a rejection turntable, a barcode scanning mechanism, a rejection mechanism, and an NG turntable. After the assembly 200, which integrates the battery cell 210 and the cup 220, enters the rejection turntable, the barcode scanning mechanism scans the cup 220 to identify unqualified battery cells 210. The rejection mechanism pushes the unqualified assembly 200 into the NG turntable, while the remaining assemblies 200 are discharged normally.

[0077] The coding equipment 100 also includes a feeding turntable 160 and a discharging turntable 170. The feeding turntable 160 is located upstream of the cup separation device 110 and is used to receive the assembly 200 from the previous process. The discharging turntable 170 is located downstream of the rejection device 150 and is used to unload the assembly 200 that has passed the coding inspection. Further details are omitted here.

[0078] The working principle of the inkjet printer 100 in this embodiment is as follows:

[0079] The feed turntable 160 receives the assembly 200, and the assembly 200 enters the cup separation device 110. The first gripper 113 holds the battery cell 210, and the second gripper 114 holds the cup 220.

[0080] The first cam turntable 111 rotates, causing the second gripper 114 to move downwards, separating the cup 220 from the battery cell 210. The top gripping part 1132 of the first gripper 113 rises under the action of the cam, causing the battery cell 210 to be adjusted to a preset height position.

[0081] The upper gripper 1222 of the inkjet jig 122 receives and holds the battery cell 210, and the lower gripper 1223 receives and holds the cup 220. Driven by the conveying mechanism 121, the cells are conveyed along the first direction X. With the cooperation of the rocker arm 1224 and the guide 123, the upper gripper 1222 rotates to adjust the battery cell 210 from a vertical state to a horizontal state, and the cup 220 is conveyed synchronously under the battery cell 210.

[0082] The coding mechanism 131 sprays QR codes onto the battery cell 210, which is kept in a horizontal position, and the scanning and detection mechanism 132 detects the spraying quality of the QR codes.

[0083] With the cooperation of the rocker arm 1224 and the guide 123, the upper gripper 1222 rotates, adjusting the battery cell 210 from a horizontal state back to a vertical state.

[0084] The third gripper 143 receives and holds the battery cell 210, and the fourth gripper receives and holds the cup 220. Driven by the second cam turntable 141, the fourth gripper drives the cup 220 to rise, and the cup 220 merges with the corresponding battery cell 210 to form the assembly 200 again.

[0085] After the assembly 200 is rejected by the rejection device 150, the qualified assembly 200 is unloaded by the unloading turntable 170.

[0086] The inkjet printer 100 of this application embodiment includes a cup separation device 110 and a cup merging device 140, which can automatically realize the merging and separation of the cup 220 and the battery cell 210. During the inkjet printing process, the cup 220 and the battery cell 210 are transported synchronously, eliminating the step of transferring the cup 220 and reducing the possibility of the inkjet printing cycle slowing down due to the disassembly and assembly process of the cup 220 and the battery cell 210, thereby improving the overall inkjet printing efficiency.

[0087] It should be noted that, where there is no conflict, the features in the embodiments of this application can be combined with each other.

[0088] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
