Description

[Technical Field]

[0001] This utility model belongs to the field of battery casing production technology, and in particular relates to a battery casing appearance inspection device. [Background Technology]

[0002] The applications of batteries are expanding further, from mobile phones and electric toys to electric vehicles and hybrid vehicles; batteries are used everywhere. Battery casings may suffer surface damage during the manufacturing process. These damaged casings not only affect the product's appearance but also pose significant safety hazards to the battery's performance. Therefore, visual inspection is necessary before the battery leaves the factory.

[0003] The specific inspection process involves observing whether the battery casing surface has local defects such as scratches or dents. If these defects are larger than a specified size, the product is considered defective. Existing technologies include automated equipment for inspecting battery casings. For example, the appearance inspection device disclosed in Chinese Patent Publication No. CN219996913U features a rotating unit formed between two adjacent rotating rollers of the battery casing conveying mechanism. This unit accommodates the battery and drives its rotation. Four first camera units are located on the side of the conveying mechanism. The rotation of the battery on the rotating unit allows the four first camera units to capture a complete image of the battery's entire appearance, thus completing a 360° photographic inspection of the battery casing's outer circumference. Two second camera units are also located on the side of the conveying mechanism to photograph the two ends of the battery casing. In this scheme, the battery casing is kept horizontal and is positioned between two rotating rollers. Four first camera units continuously take pictures of the outer periphery of the battery casing. If the battery casing is not positioned accurately and shifts, the rotating rollers will block the camera's view, resulting in incomplete pictures. This will lead to the inability to completely detect the outer periphery of the battery casing, resulting in missed detections and low detection accuracy.

[0004] For example, a lithium battery rigid body appearance inspection device disclosed in Chinese Patent Publication No. CN218360729U also has a battery casing placed horizontally on a conveyor line mechanism. When inspecting the outer periphery of the battery casing, a flipping and transporting mechanism is set up to clamp the two ends of the battery casing, lift it up and rotate it at a certain angle, and take pictures of the battery casing in conjunction with a line scanning mechanism. After taking pictures, it is placed back on the conveyor line mechanism. The flipping and transporting mechanism is not only structurally complex, but also requires clamping, lifting, lowering and resetting actions during the outer periphery inspection, which reduces the inspection cycle and thus reduces the inspection efficiency.

[0005] Therefore, it is necessary to provide a battery casing appearance inspection device to solve the above-mentioned technical problems. [Utility Model Content]

Detailed Implementation Methods

[0035] Please refer to Figures 1-5 This embodiment is a battery casing appearance inspection device. The battery casing appearance inspection device 100 includes a vibratory feeder 1 that outputs a horizontal battery casing 200, a first receiving plate 2 disposed at the output end of the vibratory feeder 1, a first conveying device 3 disposed on the front and rear sides of the first receiving plate 2 and conveying the battery casing 200, a reversing module 4 disposed above the first receiving plate 2 and changing the direction of the battery casing, an uprighting device 5 disposed at the end of the first receiving plate 2 and changing the battery casing from a horizontal state to an upright state, a conveying mechanism 6 disposed at the end of the uprighting device 5, an indexing plate 7 disposed at the end of the conveying mechanism 6, a guiding mechanism 8 disposed on the outer periphery of the indexing plate 7 and along the conveying direction of the indexing plate 7, a plurality of inspection devices 9 and a receiving device 10.

[0036] The upright device 5 includes a second receiving plate 51 disposed at the end of the first receiving plate 2 and a second conveying device 52 disposed on the front and rear sides of the second receiving plate 51 for conveying the battery casing 200. The end of the first receiving plate 2 is cantilevered and extends to the front end of the second conveying device 52. The front end of the second conveying device 52 is located above the rear end of the first conveying device 3, that is, a vertically overlapping conveying section is formed between the rear end of the first conveying device 3 and the front end of the second conveying device 52. The conveying speed of the second conveying device 52 is greater than the conveying speed of the first conveying device 3. When the battery casing is located at the end of the first receiving plate 2, the closed end on the right hangs down and the open end on the left tilts up. The second conveying device 52 changes the battery casing from a horizontal state to an upright state in the vertically overlapping conveying section and continues to convey the upright battery casing forward along the second receiving plate 51.

[0037] Both the first conveying device 3 and the second conveying device 52 include a first motor 31, a first transmission shaft 32 driven by the first motor 31 to rotate around a vertical axis, and a second transmission shaft 33 and a third transmission shaft 34 arranged in a front-to-back configuration. The upper end of the first transmission shaft 32 is provided with a first transmission wheel 321, the lower end of the second transmission shaft 33 is provided with a second transmission wheel 331, and the lower end of the third transmission shaft 34 is provided with a third transmission wheel 341. The first transmission wheel 321, the second transmission wheel 331, and the third transmission wheel 341 achieve rotational transmission through a synchronous belt 35. The first transmission wheel 321, the second transmission wheel 331, and the third transmission wheel 341 are on the same horizontal plane. The second transmission shaft 33 and the third transmission shaft 34 are arranged in a front-to-back configuration. The first transmission shaft 32 is located to the left or right of the second transmission shaft 33 and the third transmission shaft 34, that is, the first transmission shaft 32, the second transmission shaft 33, and the third transmission shaft 34 are distributed in a triangular structure, which can improve the stability of transmission.

[0038] Several fourth drive shafts 36 are arranged beside the second drive shaft 33 along the conveying direction or the opposite direction of conveying. A fourth drive wheel 332 is provided at the upper end of the second drive shaft 33. A fifth drive wheel 361 is provided on each fourth drive shaft 36. The fourth drive wheel 332 and all the fifth drive wheels 361 achieve rotational transmission through the first conveyor belt 37.

[0039] Several fifth drive shafts 38 are arranged beside the third drive shaft 34 along the conveying direction or the opposite direction of the conveying. A sixth drive wheel 342 is provided at the upper end of the third drive shaft 34. A seventh drive wheel 381 is provided on each fifth drive shaft 38. The sixth drive wheel 342 and all the seventh drive wheels 381 achieve rotational transmission through the second conveyor belt 39.

[0040] The first conveyor belt 37 and the second conveyor belt 39 are located on the front and rear sides of the first receiving plate 2 and the second receiving plate 51, and simultaneously transport battery casings. In order to improve the tension of the first conveyor belt 37 and the second conveyor belt 39, tensioning rollers 310 are provided on the inner side of the first conveyor belt 37 and the second conveyor belt 39 to tension the conveyor belts.

[0041] The second drive shaft 33, the third drive shaft 34, the fourth drive shaft 36, and the fifth drive shaft 38 are all rotatably mounted on the frame via bearings. The distance between the first conveyor belt 37 and the second conveyor belt 39 can be adjusted by adjusting the front-to-back distance between the second drive shaft 33, the third drive shaft 34, the fourth drive shaft 36, and the fifth drive shaft 38, thereby adapting to battery cases of different diameters and completing the conveying of battery cases of different diameters, with good versatility.

[0042] The battery casing 200 has a cylindrical structure with one closed end and one open end. Although the battery casings 200 are all horizontal when output from the vibratory feeder 1, it's impossible to distinguish between the closed and open ends. Therefore, some battery casings 200 output from the vibratory feeder 1 have their open ends facing right, while others have their open ends facing left. However, when entering the upright device 5, all battery casings need to have their closed ends facing right and their open ends facing left. Therefore, a reversing module 4 is needed to reverse the left and right orientation of the battery casings. The reversing module 4 includes a mounting bracket 41, a support rod 42 mounted on the mounting bracket 41 and extending horizontally above the first receiving plate 2, and a vertically downward-extending material-pulling rod 43 rotatably mounted at the end of the support rod 42. The end of the material-pulling rod 43 is equipped with a material-pulling hook 431. When the battery casing is conveyed to the right, the material-pulling hook 431 is positioned to the left, meaning the direction of the material-pulling hook 431 is opposite to the conveying direction of the battery casing. The battery casing 200 is on the first receiving plate 2, and the first conveyor belt 37 and the second conveyor belt... 39 drives the battery case forward. If the open end of the battery case faces right, the feeding hook 431 at the lower end of the feeding rod 43 will enter the battery case with the right open end, flipping the battery case upward and pushing it to the left, so that the battery case rotates 180 degrees around the horizontal axis, so that the open end of the battery case faces left and the closed end faces right. If the closed end of the battery case faces right, the feeding hook 431 cannot extend into the battery case, and the feeding rod 43 will rotate around the support rod 42, without affecting the continued forward conveying of the battery case 200.

[0043] The conveying mechanism 6 is driven by a servo motor to move the transmission belt, conveying battery cases in an upright position with the open end facing upwards and the closed end facing downwards. An arc-shaped guide rail 61 is provided at the end of the conveying mechanism 6 to facilitate the feeding of battery cases onto the indexing plate 7. Arc-shaped limiting plates 62 are provided on both the front and rear sides of the guide rail 61. The arc-shaped limiting plates 62 are tightened to the guide rail 61 with screws. Multiple sets of positioning holes 63 are provided on both the front and rear sides of the guide rail 61, each set containing multiple positioning holes 63. When the front and rear position of the arc-shaped limiting plates 62 needs to be adjusted, screws can be selectively screwed into the positioning holes 63 to adjust the distance between the two arc-shaped limiting plates 62, thus accommodating battery cases of different diameters.

[0044] The indexing plate 7 is made of transparent material, and a drive module for driving the indexing plate 7 to rotate is provided at the lower end of the indexing plate 7.

[0045] The guiding mechanism 8 includes a vertical support 81, a support frame 82 that is vertically adjustable and extends towards the center of the indexing plate 7, a first support plate 84 that is radially adjustable and mounted on the support frame 82, a second motor 85 mounted on the first support plate 84, and a guiding wheel 86 that is driven by the second motor 85 to rotate around a vertical axis. The support frame 82 is movably mounted on the vertical support 81 via a slide rail slider and is tightened with screws. To adjust the position of the support frame 82 vertically, loosen the screws, adjust the position, and then tighten them again. The first support plate 84 is movably mounted on the support frame 82 via bolts 83. To adjust the position of the first support plate 84 radially along the indexing plate 1, tighten the bolts 83. This mechanism can accommodate battery cases of different heights and diameters.

[0046] The inspection device 9 includes a first inspection camera 91, a second inspection camera 92, a third inspection camera 93, a fourth inspection camera 94, a fifth inspection camera 95, and a sixth camera module 96 arranged along the conveying direction of the indexing plate 7. The first inspection camera 91 is positioned above the indexing plate 7 and takes pictures to inspect the concentricity of the battery case opening. The second inspection camera 92 is positioned above the indexing plate 7 and takes pictures to inspect the appearance of the battery case opening and its inner bottom surface. The third inspection camera 93 is positioned below the indexing plate 7 and takes pictures to inspect the concentricity of the battery case closing end. The fourth... A fifth detection camera 94 is positioned on the side of the indexing plate 7 and takes pictures to detect the height of the battery casing. A sixth detection camera 95 is positioned below the indexing plate 7 and takes pictures to detect the appearance of the closed end of the battery casing. A sixth camera module 96 includes multiple cameras arranged at equal angles along the Z-axis. These multiple cameras are positioned above the indexing plate 7 and take pictures to detect the 360° outer perimeter of the battery casing. In this embodiment, the sixth camera module 96 has four cameras, each with a 90-degree shooting angle. The four cameras work together to take pictures to detect the 360° outer perimeter of the battery casing. The detection camera positioned below the indexing plate 7 detects the closed end of the battery casing, the detection camera positioned above the indexing plate detects the open end and the 360° outer perimeter of the battery casing, and the detection camera positioned on the side of the indexing plate 7 takes pictures to detect the height of the battery casing. Therefore, the detection device 9 can detect the appearance of the battery casing. Moreover, the indexing plate 7 is made of transparent material, which avoids obstructing the battery casing, improving detection accuracy and efficiency.

[0047] The receiving device 10 includes a scrap kicking module 101 and a good product receiving module 102. The scrap kicking module 101 includes a scrap receiving box 1011 and an air nozzle 1012 set on the scrap receiving box 1011. If a product is detected as defective, the air nozzle 1012 blows the defective product into the scrap receiving box 1011. The good product receiving module 102 includes a good product conveyor line 1021 and a baffle 1022 set above the indexing plate 1 with one end extending into the front end of the good product conveyor line 1021. When the detected qualified product is rotated to the front of the good product conveyor line 1021 by the indexing plate 1, the baffle 1022 above the indexing plate 1 blocks the battery case, and then the battery case enters the good product conveyor line 1021, completing the receiving of qualified battery cases.

[0048] When using the battery casing appearance inspection device 100 provided in this solution, the vibratory feeder 1 transports the battery casing to the first receiving plate 2. The two conveyor belts of the first conveying device 3 transport the battery casing to the right. When passing through the reversing module 4, if the open end of the battery casing faces right, the material hook 431 at the lower end of the material lever 43 will smoothly enter the interior of the battery casing with the right open end, flipping the battery casing upward and pushing it to the left, causing the battery casing to rotate 180 degrees around the horizontal axis, so that the open end of the battery casing faces left and the closed end faces right, realizing the reversal of the battery casing. If the closed end of the battery casing faces right, the material hook 431 cannot extend into the interior of the battery casing. The feeding rod 43 rotates around the support rod 42, and the battery casing 200 continues to be conveyed to the right. When the battery casing enters the end of the first receiving plate 2, the closed right end of the battery casing 200 droops downward and the open left end tilts upward. When the battery casing enters the vertically overlapping conveying section of the first conveying device 3 and the second conveying device 52, because the conveying speed of the second conveying device 52 is greater than that of the first conveying device 3, the battery casing tilts to the right again until the battery casing is upright with the open end facing upward. The lower half of the battery casing just separates from the rear end of the first conveying device 3, and can then be conveyed by the second conveying device 52. The battery casing continues to be conveyed to the second receiving plate 51, thus automatically changing the battery casing from a horizontal to an upright position, which is simple and efficient. The second conveying device 52 continues to convey the upright battery casing, which enters the conveying mechanism 6. The conveying mechanism 6 conveys the upright battery casing to the indexing plate 7. The second motor 85 drives the guide wheel 86 to rotate to guide the position of the battery casing. The first detection camera 91 takes pictures to detect the concentricity of the opening end of the battery casing. The second detection camera 92 takes pictures to detect the appearance of the opening end of the battery casing and the inner bottom surface. The third detection camera 93 takes pictures to detect the concentricity of the closed end of the battery casing. According to the inspection, the fourth inspection camera 94 takes pictures to inspect the height of the battery case, the fifth inspection camera 95 takes pictures to inspect the appearance of the closed end of the battery case, and the sixth camera module 96 includes multiple cameras arranged at equal angles along the Z-axis. The multiple cameras take pictures to inspect the 360° appearance of the outer circumference of the bearing. If the inspection results in a defective product, the air nozzle 1012 blows the defective product into the waste collection box 1011. When the qualified product is rotated by the indexing plate 1 to the front of the good product conveyor line 1021, the baffle 1022 above the indexing plate 1 blocks the battery case, and then the battery case enters the good product conveyor line 1021, completing the collection of qualified battery cases.

[0049] The above descriptions are merely some embodiments of this utility model. For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and all such modifications and improvements fall within the protection scope of this utility model.
