Description

Technical Field

[0001] This application relates to the field of battery cell processing, and in particular to a battery cell transportation inspection mechanism. Background Technology

[0002] With the rapid development of the new energy industry, battery cells, as the core component of energy storage products, directly affect the safety and performance of these products. Therefore, when battery cells are manufactured and shipped out, they need to undergo strict visual inspection to remove defective products with scratches, damage, or deformed tabs.

[0003] In existing technologies, manual sampling is commonly used to inspect the appearance of battery cells. However, due to the limitations of manual operation, this inspection method has low efficiency and cannot meet the high-efficiency requirements of large-scale production. At the same time, workers may experience visual fatigue after long hours of high-intensity work, which can easily lead to missed or false inspections, resulting in low inspection accuracy. Utility Model Content

[0004] In order to overcome the shortcomings of the prior art, this application provides a battery cell transportation inspection mechanism that can improve the detection accuracy and efficiency.

[0005] The battery cell transportation testing mechanism provided in this application adopts the following technical solution: A battery cell transport and inspection mechanism includes a transport component for transporting battery cells, a flipping component for flipping battery cells, and an inspection component for inspecting battery cells. The transport component has an inspection position during its transport stroke, and the flipping component and the inspection component are both disposed to the side of the inspection position.

[0006] By adopting the above technical solution, during the process of conveying the battery cell by the conveying component, the flipping component can flip the battery cell, and the detection component can perform appearance inspection on the periphery of the battery cell during the flipping process, which effectively improves the detection accuracy and detection efficiency.

[0007] In one specific implementation, the conveying assembly includes two belt conveyors arranged side by side with a gap between them. A lifting assembly for lifting the battery cell is disposed in the gap, and the lifting assembly is located at the detection position.

[0008] By adopting the above technical solution, the lifting component can lift the battery cell that has reached the detection position upwards, which facilitates the flipping component to flip the battery cell and prevents the conveying component from interfering with the flipping of the battery cell.

[0009] In one specific implementation, the lifting assembly includes a liftable lifting plate and a first drive module for driving the lifting plate to move up and down.

[0010] In one specific implementation, the flipping assembly includes two symmetrical clamps arranged on both sides of the detection position. The two clamps are rotatable and can be translated along directions that move closer or further apart from each other. The flipping assembly also includes a second drive module for driving the clamps to rotate and a third drive module for driving the clamps to translate.

[0011] By adopting the above technical solution, the two clamping plates can clamp and flip the battery cell during their respective translational and rotational strokes, effectively improving the flipping stability of the battery cell.

[0012] In one specific implementation, the extension direction of the rotation axis of the clamping plate and the translation direction of the clamping plate are perpendicular to the conveying direction of the conveying assembly.

[0013] In one specific implementation, sleeves are coaxially provided on one side of the two clamping plates that are close to each other, and the inner contour of the sleeves matches the outer contour of the battery cell.

[0014] By adopting the above technical solution, the two clamping plates can respectively limit the two ends of the battery cell through two sleeves, preventing the battery cell from falling off during the flipping process.

[0015] In one specific implementation, the flipping assembly further includes two symmetrically arranged flipping frames on both sides of the detection position, with the two clamping plates respectively arranged on the upper ends of the two flipping frames.

[0016] By adopting the above technical solution, the installation strength of the clamping plates is effectively improved, thereby enabling the two clamping plates to stably clamp and flip the battery cell.

[0017] In one specific implementation, the detection component includes a detection frame and a camera disposed on the upper end of the detection frame.

[0018] By adopting the above technical solution, the camera can capture and analyze images of the battery cells that have reached the detection position, effectively improving the detection accuracy.

[0019] In one specific implementation, the conveying assembly also has a waste discharge position during its conveying stroke. The waste discharge position is located at the rear end of the detection position, and a waste discharge assembly is provided on the side of the waste discharge position.

[0020] By adopting the above technical solution, after the detection component detects defective products, the waste discharge component can discharge the defective products that have reached the waste discharge position, thereby improving the quality of the output battery cells.

[0021] In one specific implementation, the waste discharge assembly includes a waste discharge rack located on one side of the waste discharge location, a translatably movable push plate located on the waste discharge rack, a fourth drive module for driving the push plate to translate, and a collection box located on the other side of the waste discharge location, wherein the translation direction of the push plate is the same as the direction from the waste discharge rack to the collection box.

[0022] By adopting the above technical solution, the pusher plate can quickly and accurately push the defective products that have reached the waste discharge position into the collection box, which not only improves the waste discharge efficiency, but also allows the defective products to be collected in the collection box, making it convenient for workers to pick up the defective products and reprocess them.

[0023] In summary, this application includes at least one of the following beneficial technical effects: During the process of conveying the battery cells by the conveying component, the flipping component can flip the battery cells, and the detection component can perform appearance inspection on the periphery of the battery cells during the flipping process, which effectively improves the detection accuracy and efficiency.

[0026] The present application will be further described in detail below with reference to the accompanying drawings.

[0027] See Figure 1 As shown, a battery cell transport and inspection mechanism includes a transport assembly 1 for transporting battery cells, a flipping assembly 2 for flipping battery cells, and an inspection assembly 3 for inspecting battery cells. The transport assembly 1 has an inspection position during its transport stroke, and the flipping assembly 2 and the inspection assembly 3 are both located to the side of the inspection position.

[0028] During the process of conveying the battery cell by the conveying component 1, the flipping component 2 can flip the battery cell, and the detection component 3 can perform appearance inspection on the periphery of the battery cell during the flipping process, which effectively improves the detection accuracy and detection efficiency.

[0029] In this embodiment, the conveying assembly 1 includes two belt conveyors 11 arranged side by side. The belt conveyors 11 are existing technology. The two belt conveyors 11 operate synchronously and their conveying directions are the same. There is a gap between the two belt conveyors 11, and a lifting assembly 4 for lifting the battery cell is disposed in the gap. The lifting assembly 4 is located at the detection position.

[0030] Specifically, the lifting assembly 4 includes a liftable lifting plate 41 and a first drive module 42 for driving the lifting plate 41 to rise and fall. The first drive module 42 is a lifting cylinder, and the lifting plate 41 is horizontal and located at the end of the piston rod of the lifting cylinder. When the battery cell reaches the detection position, the lifting plate 41 rises and lifts the battery cell upward, facilitating the flipping assembly 2 to flip the battery cell and preventing the conveying assembly 1 from interfering with the flipping of the battery cell.

[0031] In this embodiment, the flipping assembly 2 includes two symmetrically arranged flipping frames 25 on both sides of the detection position. Each of the two flipping frames 25 has a clamping plate 21 at its upper end. The height of the two clamping plates 21 is greater than the height of the belt conveyor 11. The two clamping plates 21 are rotatable and can be translated along directions that allow them to approach or move away from each other. Furthermore, the extension direction of the rotation axis of the clamping plates 21 and the translation direction of the clamping plates 21 are perpendicular to the conveying direction of the conveying assembly 1. After the lifting plate 41 lifts the battery cell upwards, the two clamping plates 21 can come together and clamp the battery cell. Subsequently, the two clamping plates 21 rotate and cause the battery cell to flip, enabling the detection assembly 3 to detect the peripheral portion of the battery cell.

[0032] The flipping assembly 2 also includes a second drive module 22 for driving the clamping plate 21 to rotate and a third drive module 23 for driving the clamping plate 21 to translate. The second drive module 22 is a motor and the third drive module 23 is a translation cylinder. The translation cylinder is located at the upper end of the flipping frame 25, and the motor is located on the piston rod of the translation cylinder. The clamping plate 21 is upright and located on the output shaft of the motor.

[0033] In this embodiment, sleeves 24 are coaxially arranged on the sides of the two clamping plates 21 that are close to each other, and the inner contour of the sleeves 24 matches the outer contour of the battery cell. The two clamping plates 21 can limit the two ends of the battery cell through the two sleeves 24 respectively, preventing the battery cell from falling out during the flipping process.

[0034] In this embodiment, the detection component 3 includes a detection frame 31 and a camera 32 disposed on the upper end of the detection frame 31. The detection frame 31 includes two first frame bodies 311 respectively erected on both sides of the detection position, and a second frame body 312 connected to the two first frame bodies 311 at both ends. The extending direction of the second frame body 312 is perpendicular to the conveying direction of the conveying component 1. The camera 32 is disposed on the lower middle part of the second frame body 312 and directly above the detection position. The camera 32 is a smart camera in the prior art, capable of capturing and analyzing images of the battery cells arriving at the detection position to identify defective products.

[0035] In this embodiment, the conveying assembly 1 also has a waste discharge position during its conveying stroke. The waste discharge position is located at the rear end of the detection position, and a waste discharge assembly 5 is arranged to the side of the waste discharge position. If the camera 32 determines that the detected battery cell is a defective product, the waste discharge assembly 5 discharges the defective product to the outside to improve the quality of the output battery cell.

[0036] Specifically, the waste discharge assembly 5 includes a waste discharge frame 51 located on one side of the waste discharge position, a movable push plate 52 located on the waste discharge frame 51, a fourth drive module 53 for driving the push plate 52 to move, and a collection box 54 located on the other side of the waste discharge position. The height of the push plate 52 is the same as the height of the belt conveyor 11, and the direction of translation of the push plate 52 is the same as the direction from the waste discharge frame 51 to the collection box 54. The waste discharge frame 51 and the collection box 54 are symmetrically arranged about the conveying assembly 1. The direction of translation of the push plate 52 is perpendicular to the conveying direction of the conveying assembly 1. The fourth drive module 53 is a translation cylinder located on the waste discharge frame 51, and the push plate 52 is upright and located on the piston rod of the translation cylinder.

[0037] After the defective product reaches the waste discharge position, the controller controls the push plate 52 to move and push the defective product quickly and accurately into the collection box 54. This not only improves the waste discharge efficiency, but also allows the defective product to be contained in the collection box 54, making it convenient for workers to pick up the defective product and reprocess it.

[0038] In this embodiment, a transition plate 6 is also provided between the two belt conveyors 11. The transition plate 6 is located at the waste discharge position and can support the defective products when the pusher plate 52 pushes them, so that the defective products can smoothly enter the collection box 54.

[0039] In this embodiment, the battery cell transportation and detection mechanism is also equipped with a PLC controller, which can perform overall control on the conveying process of the conveying component 1, the lifting process of the lifting component 4, the flipping process of the flipping component 2, and the waste discharge process of the waste discharge component 5.

[0040] The implementation principle of a battery cell transportation inspection mechanism according to an embodiment of this application is as follows: The conveying assembly 1 conveys the battery cell forward. When the battery cell reaches the detection position, the lifting assembly 4 lifts the battery cell upward. Then, the flipping assembly 2 clamps and flips the battery cell. During the flipping process, the detection assembly 3 takes pictures and detects the periphery of the battery cell. Then, the flipping assembly 2 and the lifting assembly 4 are reset and the battery cell is sent back to the conveying assembly 1. The conveying assembly 1 continues to convey the battery cell. When the battery cell reaches the waste discharge position, if the battery cell is a defective product, the waste discharge assembly 5 discharges the defective product. If the battery cell is a qualified product, the waste discharge assembly 5 does not work, and the conveying assembly 1 continues to convey the qualified product forward.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
