Description

Technical Field

[0001] The present invention relates to the technical field of battery detection, and in particular to a battery sealing detection device for an electric tugboat. Background Art

[0002] At present, the tentacles of new energy have extended to the field of ships. More and more power battery companies are setting their sights on the sub-sector of ship electrification and developing marine power battery systems in a targeted manner. Like new energy vehicles, the performance indicators, safety, charging speed, and distribution of charging facilities of power batteries are also the main factors affecting the development of electric ships. In the process of power battery production, they need to be sealed after the electrolyte solution is injected. In order to ensure the quality of the battery seal, an optical detector will be used to inspect the battery seal after production to prevent unqualified batteries from flowing out.

[0003] A cylindrical battery shell defect detection device with publication number CN116183630A in the prior art uses a compression belt to compress the cylindrical battery shell to drive its rotation, so that the cylindrical battery shell rotates one circle at the detection station, and collects data through a shooting device to efficiently and quickly detect defects on the side of the cylindrical battery shell. A compression belt and a drive motor are provided in the detection device, which can realize the detection of cylindrical battery shells supported by pairs of rollers on a rotating plate, thereby reducing costs.

[0004] Although the efficiency of battery inspection can be improved, there are still some defects in the actual inspection process. Since the unqualified and qualified product unloading mechanism of the inspection device can only push the battery from the inspection line and then slide it into the material box by the battery's own gravity, the batteries in the material box will be disordered, and the batteries after inspection cannot be neatly placed in the material box to facilitate subsequent production. Therefore, after the inspection is completed, workers are required to stack the batteries, or purchase sorting equipment to sort the batteries. This is not only time-consuming and labor-intensive, but also greatly reduces the production efficiency of the device.

DETAILED DESCRIPTION

[0028] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0030] The unloading mechanism includes a rectangular block 12, which is slidably connected to the inner side of the driving cavity 8 and close to one end of the conveying plate 3. The side wall of the conveying plate 3 and the position corresponding to the unloading block 5 are provided with a through groove 6. The side wall of the rectangular block 12 is fixedly connected with an L-shaped rod 13 and penetrates the through groove 6. The top of the L-shaped rod 13 is fixedly connected with a push rod 14 for pushing out the battery. A reciprocating mechanism for pulling the rectangular block 12 back and forth is provided in the driving cavity 8;

[0031] The rear side of the unloading block 5 is rotatably connected with a circular sorting disk 16, and the outer wall of the sorting disk 16 is provided with four sorting grooves 17. A limiting plate 18 for limiting is provided on the rear side of the sorting disk 16. A circular limiting cylinder 19 is fixedly connected to the rear side of the unloading table 2 and located on the outer side of the sorting disk 16. An outlet 20 is provided at the bottom of the limiting cylinder 19. An adjusting rod 21 is fixedly connected to the front side of the sorting disk 16 through the driving cavity 8. Four straight grooves 22 and four inclined grooves 23 are equidistantly provided on the outer wall of the adjusting rod 21, and the two ends of the four inclined grooves 23 are connected to the two ends of the adjacent two straight grooves 22. An inward card groove 24 is provided on the inner side of the inclined groove 23 and close to one end of the sorting disk 16. A top plate 25 is slidably connected to the inner side of the cavity 8 and above the adjusting rod 21, a connecting rod 26 is fixedly connected between the top plate 25 and the rectangular block 12, a pull pin 27 is slidably connected through the top of the top plate 25, and the bottom of the pull pin 27 is inserted into the inner side of one of the straight grooves 22, a spring 28 is fixedly connected between the top of the top plate 25 and the outer wall of the pull pin 27, a step is provided between the clamping groove 24 and the straight groove 22, and the connection between the clamping groove 24 and the oblique groove 23 is inclined, through the setting of the clamping groove 24, the pull pin 27 can slide to the end of the straight groove 22 and then move to the oblique groove 23 when resetting, and the adjusting rod 21 is pulled to rotate, thereby ensuring the normal operation of the device;

[0032] The reciprocating mechanism includes a servo motor 9. A through groove 10 is provided at the top of the unloading platform 2 and below the unloading block 5. The servo motor 9 is fixedly connected to the bottom of the unloading platform 2 and is located inside the through groove 10. The output end of the servo motor 9 passes through the bottom of the driving cavity 8 and is fixedly connected to a disc 11. A pull rod 15 is connected between the eccentric part of the top of the disc 11 and the top of the rectangular block 12 through a hinge. The servo motor 9 is electrically connected to the controller on the spectrum detection machine 1. The two unloading blocks 5 are divided into a qualified product unloading area and an unqualified product unloading area. The unqualified products are detected by the spectrum probe of the spectrum detection machine 1 and the data is transmitted to the controller. Then, when the unqualified battery moves to the unqualified unloading area, the corresponding servo motor 9 will be controlled to start and automatically push the battery out.

[0033] When the power battery is inspected by the spectrum inspection machine 1 and is transported to the side of the material block 5 by the intermittent conveying mechanism 4, the controller will control the corresponding servo motor 9 to start according to whether the battery is qualified, and the servo motor 9 starts to drive the disc 11 to rotate, thereby driving the hinged pull rod 15 to rotate in a circle, and then the pull rod 15 pulls the rectangular block 12 to slide in the driving cavity 8, thereby driving the L-shaped rod 13 and the push rod 14 to move, and push the battery on the intermittent conveying mechanism 4 into the conveying slot 7. This is repeated to push the battery neatly into the conveying slot 7. When the battery is pushed to the side of the sorting plate 16, the frontmost battery will be squeezed into the sorting slot 17 under the thrust of the next battery push;

[0034] At the same time, the connecting rod 26 will drive the top plate 25 to move, and then drive the pulling pin 27 to move in the straight groove 22. Then, when the disk 11 rotates half a circle, the pulling pin 27 will move to the end of the straight groove 22, just above the slot 24, so that under the elastic force of the spring 28, the bottom of the pulling pin 27 is pushed to insert into the slot 24. Then the disk 11 continues to rotate, which will push the pulling rod 15 to reset, and at the same time drive the rectangular block 12, the L-shaped rod 13 and the push rod 14 to reset, and then drive the top plate 25 and the pulling pin 27 to reset through the connecting rod 26. At this time, since there is a step between the slot 24 and the straight groove 22, the pulling pin 27 will slide into the inclined groove 23, and then under the pulling of the connecting rod 26, the pulling pin 27 will be driven to move in the inclined groove 23, and the top plate 25 is restricted by the driving chamber 8 and cannot rotate, thereby driving the adjusting rod 21 to rotate 90 degrees, and then driving the sorting plate 16 to rotate 90 degrees, and the sorting groove 17 will be rotated to the bottom outlet 20 in turn, and then the battery will fall onto the sponge block 31 of the material box 30 under its own gravity, thereby realizing automatic sorting of qualified and unqualified batteries after the inspection is completed, and neatly stacking them in the material box 30, which can prevent the batteries from rolling down at will and causing chaos, which is beneficial to the subsequent packaging or transportation of the batteries.

[0035] In order to further improve the smoothness of the unloading process, the conveying trough 7 is arranged near the side of the conveying plate 3 to be in the shape of a trumpet that opens to both sides. The trumpet-shaped arrangement can avoid deviations in the position of the conveying trough 7 and the V-groove on the intermittent conveying mechanism 4, which would cause the battery to fail to be pushed in. Thus, the trumpet-shaped arrangement can enlarge the end of the conveying trough 7 to ensure the normal pushing of the battery and avoid affecting the normal operation of the device.

[0036] In order to further improve the sorting effect of the device, a sliding frame 29 is slidably connected to the rear side of the unloading platform 2 and below the outlet 20, a material box 30 for placing batteries is slidably connected to the inner side of the sliding frame 29, and a sponge block 31 with a V-shaped groove is provided on the inner side of the material box 30, a rack groove 32 is opened on the top of the sliding frame 29, and a plurality of tooth blocks 33 are fixedly connected to the outer wall of the sorting plate 16 and located between the sorting grooves 17, and the plurality of tooth blocks 33 are meshed with the rack grooves 32;

[0037] When the servo motor 9 is working to sort and detect the batteries, the rotation of the sorting plate 16 will drive the tooth block 33 to rotate. Then, when the tooth block 33 rotates to the bottom, it will drive the sliding frame 29 to move on the rear side of the unloading table 2 through the meshing rack groove 32, and then drive the material box 30 to move, and move the position where the batteries were placed last. The batteries can be automatically placed in the material box 30 without the need for workers to take them out and place them. Moreover, when the sorting groove 17 rotates to the exit 20, it will drive the tooth block 33 to rotate out of the rack groove 32. At this time, if the material box 30 is full, the sliding frame 29 can be pushed back, and the material box 30 can be pulled out and replaced with a new one.

[0038] In order to be able to adjust the length of the batteries sorted by the unloading mechanism each time according to the length of the detected batteries, a fixed frame 34 is fixedly connected to the middle position of the rear side of the sorting disk 16, a screw 35 is rotatably connected to the inner side of the fixed frame 34, a sliding block 36 is threadedly connected to the outer wall of the screw 35, the outer wall of the sliding block 36 passes through the fixed frame 34 and is fixedly connected to the limit plate 18, and a hand wheel 37 is fixedly connected to the rear side of the screw 35 through the fixed frame 34, and a slide groove 41 is penetrated and opened on the side wall of the sorting disk 16 and located below the sorting groove 17, and an extension plate 38 is fixedly connected to the side wall of the limit plate 18 and at a position corresponding to the slide groove 41;

[0039] When the position of the limit plate 18 needs to be adjusted according to the length of the detected battery, the screw 35 is driven to rotate by rotating the hand wheel 37, which in turn drives the threaded sliding block 36 to move, thereby driving the limit plate 18 to move inside the limit cylinder 19, and at the same time drives the extension plate 38 to be inserted into the corresponding slide groove 41, thereby realizing the adjustment of the distance between the limit plate 18 and the sorting disk 16 to ensure the normal unloading of batteries of different lengths. It should be noted here that since the width of the conveyor belt on the intermittent conveying mechanism 4 is fixed, batteries of different lengths can be placed on the conveyor belt. However, the distance pushed by the push rod 14 each time is also fixed. There will be a period of empty movement when pushing shorter batteries. When the battery on the conveyor belt is not in contact, the battery in the conveying groove 7 will not be pushed to move. Therefore, the position of pushing the battery into the sorting groove 17 is determined according to the length of the battery, and batteries of different sizes can be pushed into sorting grooves 17 of different lengths.

[0040] In order to facilitate the precise adjustment of the position of the limit plate 18, a length scale value 39 is opened on the top of the fixed frame 34, and a pointer 40 is fixedly connected to the rear side of the sliding block 36 and above the length scale value 39. When the hand wheel 37 is turned to adjust the position of the limit plate 18, the pointer 40 will be driven to move, and then the moving position of the pointer 40 on the length scale value 39 is observed. The position of the limit plate 18 can be accurately adjusted according to the length of the detected battery to avoid deviation in the adjustment position and the problem of battery jamming.

[0041] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only describe the principles of the present invention. The present invention may be subject to various changes and improvements without departing from the spirit and scope of the present invention.
