[0001] The utility model belongs to the technical field of battery production, and particularly relates to an automatic monitoring and repair welding device for battery welding defects. Background Technique

[0002] In the process of battery manufacturing and production, laser welding is a very important and common technology. Essentially, laser welding is a severe heat conduction effect inside the material under a high-energy beam heat source.

Therefore, other examples of the exemplary embodiments may have different values. It should be noted that: similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0044] Embodiment 1:

[0045] This embodiment provides an automatic monitoring and repair welding device for battery welding defects, including:

[0046] A frame, including a welding detection station 1 and a post-welding re-inspection station 2;

[0047] A welding detection module 3, arranged on the welding detection station 1, and the welding detection module 3 includes a first detection mechanism for detecting the battery in the welding detection station 1 and a welding mechanism for repairing the battery with detected welding defects;

[0048] A post-welding re-inspection module 4, arranged on the post-welding re-inspection station 2, and the post-welding re-inspection module 4 includes a second detection mechanism for re-inspecting the battery in the post-welding re-inspection station 2;

[0049] A first transfer module 5, arranged on the welding detection station 1, for driving the movement of the welding detection module 3;

[0050] A second transfer module 6, arranged on the post-welding re-inspection station 2, for driving the movement of the post-welding re-inspection module 4;

[0051] A transport mechanism 7, for transporting the battery that has been detected and repaired in the welding detection station 1 to the post-welding re-inspection station 2.

[0052] In this technical solution, as Figure 1 、Figure 2 As shown in the figure, the welding detection module 3 can be freely moved along the first direction Z, the second direction Y, and the third direction X by the first transfer module 5, and the post-welding re-inspection module 4 can be freely moved along the first direction Z, the second direction Y, and the third direction X by the second transfer module 6. After the abnormal batteries after laser welding processing are fed in, they are first transported to the welding detection station 1 by the transport mechanism 7. The first transfer module 5 drives the welding detection module 3 to move. The first detection mechanism first performs the detection work, detects the movement trajectory according to the size of the battery, then identifies the welding area on the trajectory, finds out the welding defect points, judges the type and size of the defects and records them. After all the abnormal points of the batteries are identified and recorded, the first transfer module 5 drives the welding detection module 3 to reset, and the detection work is completed; then the first transfer module 5 drives the welding detection module 3 to move again to let the welding mechanism perform the repair welding work, move according to the detection trajectory and emit light for welding at the defective part.

[0053] The batteries after the repair welding are transported to the post-welding re-inspection station 2 by the transport mechanism 7. The second transfer module 6 drives the post-welding re-inspection module 4 to move, and the second detection mechanism performs the re-inspection work. After the re-inspection is problem-free, the batteries are transported to the subsequent processes by the transport mechanism 7.

[0054] In summary, the first detection mechanism and the welding mechanism of the welding detection module 3 can automatically detect and re-weld the defective parts on the welded batteries, without manual detection and re-welding of defective batteries. Then, the post-welding re-inspection module 4 can detect the re-welded batteries to ensure the production quality of the batteries, effectively improving the production efficiency of battery manufacturing and the battery yield.

[0055] Embodiment 2:

[0056] This embodiment provides an automatic monitoring and repair welding device for battery welding defects. In addition to including the technical solutions of the above embodiment, it also has the following technical features.

[0057] Furthermore, it further includes:

[0058] A carrier table 8, which is placed on the transport mechanism 7 and can move along the transport mechanism 7. The carrier table 8 is used to place the batteries to be inspected;

[0059] A first lifting mechanism, which is arranged below the welding detection module 3. When the carrier table 8 with the batteries to be inspected moves below the welding detection module 3, the first lifting mechanism is used to drive the lifting of the carrier table 8;

[0060] A second lifting mechanism, which is arranged below the post-welding re-inspection module 4. When the carrier table 8 with the batteries to be inspected moves below the post-welding re-inspection module 4, the second lifting mechanism is used to drive the lifting of the carrier table 8.

[0061] In this technical solution, asFigure 3 As shown in Figure 3 , the transport mechanism 7 can be two parallel conveyor belts. The battery to be inspected is placed on the carrier table 8, and the carrier table 8 is arranged on the two conveyor belts. The movement of the two conveyor belts drives the carrier table 8 to move, realizing the transportation of the battery to be inspected. Both the first lifting mechanism and the second lifting mechanism can be composed of a cylinder and a support plate. The cylinder is installed on the work station, and the support plate is installed on the output end of the cylinder for contacting and supporting the bottom of the carrier table 8. The cylinder drives the support plate to lift and lower, driving the carrier table 8 to lift and lower, realizing the separation between the carrier table 8 and the transport mechanism 7.

[0062] When the carrier table 8 is transported by the transport mechanism 7 to the lower part of the welding inspection module 3, the first lifting mechanism is used to drive the carrier table 8 to rise as a whole, separating the carrier table 8 from the transport mechanism 7. The transport mechanism 7 can no longer drive the carrier table 8 to move. Then, the welding inspection module 3 performs the inspection and re-welding work. After the inspection and re-welding work is completed, the first lifting mechanism drives the carrier table 8 to descend as a whole, so that the carrier table 8 returns to the transport mechanism 7 again and is transported by the transport mechanism 7 to the post-welding inspection station 2.

[0063] When the carrier table 8 is transported by the transport mechanism 7 to the lower part of the post-welding inspection module 4, similarly, the second lifting mechanism is used to drive the carrier table 8 to rise as a whole, and then the re-inspection work is carried out. After the re-inspection work is completed, the second lifting mechanism drives the carrier table 8 to descend as a whole and is transported by the transport mechanism 7 to the subsequent processes.

[0064] Embodiment 3:

[0065] This embodiment provides an automatic monitoring and repair welding device for battery welding defects. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0066] Furthermore, it further includes:

[0067] Two blocking mechanisms 9 are respectively arranged at the discharge ends of the welding inspection station 1 and the post-welding inspection station 2. The blocking mechanism 9 is used to control whether the carrier table 8 moves with the transport mechanism 7.

[0068] In this technical solution, when the carrier table 8 moves to the welding inspection station 1 or the post-welding inspection station 2 along with the movement of the transport mechanism 7, the blocking mechanism 9 can be used to limit the movement of the carrier table 8, ensuring that the carrier table 8 stops moving under the welding inspection module 3 or the post-welding inspection module 4, and then is lifted by the lifting mechanism for inspection, welding work or re-inspection work.

[0069] Furthermore, the blocking mechanism 9 includes:

[0070] A blocking member;

[0071] A driving unit for driving whether the blocking member is located on the transport path of the carrier table 8.

[0072] In this technical solution, the driving unit can be a cylinder, and the blocking member is installed on the output end of the cylinder. When the carrier 8 moves to the working station, the driving unit drives the blocking member to rise onto the transportation path of the carrier 8, and then the blocking member abuts against the carrier 8, thereby realizing the movement restriction of the carrier 8.

[0073] Embodiment 4:

[0074] This embodiment provides an automatic monitoring and repair welding device for battery welding defects. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0075] Furthermore, the welding detection module 3 includes:

[0076] A base, installed on the mobile end of the first transplanting module 5;

[0077] A welding monitor 31, installed on the base and used to identify welding defects on the battery to be inspected;

[0078] A welding laser 32, installed on the base and used to repair weld the battery with welding defects.

[0079] In this technical solution, the industrial control computer controls the first transplanting module 5 to drive the base to move along the third direction X, the second direction Y, and the first direction Z, driving the welding monitor 31 to scan the welding profile of each abnormal battery according to the battery size, detect and identify welding defect points, judge and record the types and sizes of the defects and upload them to the industrial control computer. After all defect points are completely identified and recorded, the industrial control computer controls the first transplanting module 5 to drive the base to move according to the path signal of the defect points, driving the welding laser 32 to move. At the same time, the welding laser 32 emits light to weld the defective part, completing the repair welding work.

[0080] Furthermore, the welding monitor 31 is rotatably installed on the base. Through this structural design, the detection angle of the welding monitor 31 can be controlled, so as to be able to adapt to abnormal batteries of different types and sizes.

[0081] Furthermore, the welding detection module 3 further includes an automatic wire feeding component 33, installed on the welding laser 32 and used to feed welding wire. Through this structural design, when the welding laser 32 is performing repair welding operations and there is a situation of missed welding, the automatic wire feeding component 33 starts to feed the welding wire into the welding joint, and the welding laser 32 emits light to melt the welding wire and then flows out to fill the defect.

[0082] Further, the welding detection module 3 further includes a dust suction component 34, which is installed on the first base and used to suck dust during the welding of the welding laser 32. The dust suction component 34 can be a negative pressure dust removal pipe. Through this structural design, when the welding laser 32 performs repair welding operations, the dust suction component 34 can suck the welding slag generated by the repair welding, reduce the amount of dust in the working environment, and reduce environmental pollution.

[0085] Further, the post-welding re-inspection module 4 includes:

[0086] A profiler 41, which is installed on the mobile end of the second transplanting module 6 and used to re-inspect the battery located in the post-welding re-inspection station 2.

[0087] In this technical solution, the second transplanting module 6 drives the profiler 41 to move along the third direction X, the second direction Y, and the first direction Z. The profiler 41 is used to comprehensively detect the repaired battery. After confirming that the battery has no welding defects, it is transported to the subsequent processes through the transport mechanism 7.

[0088] Embodiment 6:

[0089] This embodiment provides an automatic monitoring and repair welding device for battery welding defects. In addition to including the technical solutions of the above embodiments, it also has the following technical features.

[0090] Further, both the first transplanting module 5 and the second transplanting module 6 include a first-direction transplanting unit 101 for realizing the movement in the first direction Z, a second-direction transplanting unit 102 for driving the first-direction transplanting unit 101 to move along the second direction Y, and a third-direction transplanting unit 103 for driving the second-direction transplanting unit 102 to move along the third direction X.

[0091] In this technical solution, through this structural design, the independent movement of the welding detection module 3 and the post-welding re-inspection module 4 in the third direction X, the second direction Y, and the first direction Z is realized, improving flexibility and ensuring that the welding detection module 3 and the post-welding re-inspection module 4 can perform precise operations on the battery, with high practicality.
