Description

Technical Field

[0001] The utility model belongs to the technical field of lithium battery cover plate production, and particularly relates to a liquid injection hole detection device. Background Technique

[0002] After the light aluminum sheet of the lithium battery cover plate is processed and formed, it needs to be subjected to multiple function detections on an automatic inspection line electric function turntable machine. The detection principle is to install corresponding detection heads above the automatic inspection line electric function turntable machine. By controlling the rotation of the automatic inspection line electric function turntable machine, the light aluminum sheet to be detected is moved to the detection station, and then the detection head is controlled to automatically move down and contact the light aluminum sheet, so as to complete the detection of the light aluminum sheet. The liquid injection holes on the light aluminum sheet of the lithium battery cover plate are required to be circular, and the diameter size has a fixed standard. Non-circular and size deviation will affect the actual effect of the liquid injection holes.

[0003] At present, in the actual production process, the shape and size of the liquid injection holes are detected by manual visual inspection to judge whether the shape is standard and whether the size meets the standard. Since the standard size of the liquid injection holes is very small, generally about 1 cm in diameter, after processing and forming, if there is a size deviation, it is often a deviation at the mm level. Under such subtle differences, it is very difficult to find problems visually, and it is even more difficult to judge if the shape is slightly non-standard. Summary of the Utility Model

Detailed implementation manners

[0021] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the technical field to which this application belongs; the terms used in the specification of this application are only for the purpose of describing specific embodiments and are not intended to limit this application; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above drawings are intended to cover non-exclusive inclusion. The terms "first", "second", etc. in the specification and claims of this application or the above drawings are used to distinguish different objects and not to describe a specific order; the terms "inner", "outer", "left", "right" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus cannot be construed as a limitation of the present utility model.

[0022] Reference to "embodiment" herein means that a particular feature, structure, or characteristic described in connection with the embodiment can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0023] An embodiment of the present utility model provides a liquid injection hole detection device, as Figures 1-5As shown in the figure, the liquid injection hole detection device includes: a support plate 1 provided on an automatic inspection line electric function turntable machine; a detection head 2 installed on the support plate 1; an installation groove 3 opened at the bottom of the support plate 1, and an installation block 4 is slidably provided in the installation groove 3; a detection probe 5 fixedly installed at the bottom of the installation block 4; and an installation mechanism provided on the support plate 1 for assembling the installation block 4.

[0024] In this embodiment, a liquid injection hole detection probe 5 is added above the automatic inspection line electric function turntable machine; the liquid injection hole detection probe 5 and the original detection head 2 are fixed on the same support plate 1 and are located directly above the liquid injection hole of the optical aluminum sheet to be detected. The liquid injection hole detection probe 5 is connected to the control system of the automatic inspection line electric function turntable machine through a signal line. The detection probe 5 is made of silica gel, and the bottom contact surface is a standard circular bottom surface, and the diameter is slightly smaller than the standard diameter of the liquid injection hole, so that the detection probe 5 can just extend into the liquid injection hole;

[0025] While the automatic inspection line electric function turntable machine realizes other function detections, by using the characteristic of the up and down movement of other detection heads 2, the liquid injection hole detection probe 5 also makes an up and down movement at the same time. When there are deviations in the shape and size of the liquid injection hole, the liquid injection hole detection probe 5 will not be able to smoothly extend into the liquid injection hole. At this time, other detection heads 2 will not be able to smoothly perform detections, which will cause the system to alarm. When the shape and size of the liquid injection hole meet the standards, during the detection process, the liquid injection hole detection probe 5 can smoothly extend into the liquid injection hole, then no alarm will be caused, and the detection can be successfully completed and enter the next link. By using the detection head 2 and the detection probe 5 in combination, compared with manual visual inspection, this device can achieve a detection accuracy of micrometers or even finer, effectively avoiding misjudgment and missed detection caused by human factors, while reducing manual intervention, which can effectively improve the detection speed, ensure the consistency of detection quality, and thus improve the overall production efficiency.

[0026] In a further preferred embodiment of the present invention, the installation mechanism includes: an installation cavity 6 opened in the support plate 1, a connection groove 7 is opened on one side of the installation cavity 6, and the connection groove 7 communicates with the installation groove 3; a bidirectional screw 8 rotatably installed in the installation cavity 6, and one end of the bidirectional screw 8 extends out of the support plate 1; a set of sliders 9 threadedly sleeved on the bidirectional screw 8; a set of clamping plates 10 respectively fixedly installed on the set of sliders 9, and a set of clamping plates 10 all extend into the connection groove 7; a set of fixing grooves 11 opened on the installation block 4, and the set of fixing grooves 11 are slidably connected with the set of clamping plates 10.

[0027] In this embodiment, since the detection probe 5 is supported by silica gel, during long-term use, the bottom end of the detection probe 5 will be worn. When the wear of the detection probe 5 is relatively large and it needs to be replaced, first, rotate the bidirectional screw 8 to drive a set of sliders 9 to slide, so that a set of sliders 9 drive the clamping plates 10 to slide away from each other, thereby enabling a set of clamping plates 10 to slide away from the fixing groove 11. Then, the mounting block 4 can be removed from the mounting groove 3. The operation is relatively fast. Through the precise cooperation of the bidirectional screw 8 and the slider 9, and the sliding connection between the clamping plate 10 and the fixing groove 11, the rapid installation operation of the detection probe 5 is realized.

[0028] In a further preferred embodiment of the present invention, a circular plate 12 is fixedly installed on one side of the support plate 1. One end of the bidirectional screw 8 is fixedly sleeved with a circular plate 13. The circular plate 13 is located on one side of the circular plate 12. A connecting bolt 14 is threadedly installed on the circular plate 13. One end of the connecting bolt 14 is in contact with the circular plate 12.

[0029] In this embodiment, when rotating the bidirectional screw 8, first remove the connecting bolt 14 from the circular plate 13, and then the bidirectional screw 8 can be rotated. Through the combined use of the circular plate 12, the circular plate 13 and the connecting bolt 14, the firm fixation of the bidirectional screw 8 is realized, effectively preventing its loosening or displacement during the working process and enhancing the overall stability of the device.

[0030] In a further preferred embodiment of the present invention, anti-slip pads 15 are installed on one side of the circular plate 12 and the clamping plate 10. The materials of the plurality of anti-slip pads 15 are all silica gel materials.

[0031] In this embodiment, by adding the anti-slip pads 15, the stability between the circular plate 12 and the clamping plate 10 and their respective contact surfaces is significantly improved, reducing the possibility of component loosening or slipping caused by vibration or external forces.

[0032] In a further preferred embodiment of the present invention, a limiting cavity 16 is formed in the support plate 1. A trapezoidal block 17 is fixedly installed on the top of the mounting block 4. The trapezoidal block 17 is slidably connected to the limiting cavity 16. A clamping block 18 is slidably arranged in the limiting cavity 16. The clamping block 18 is clamped in the card slot of the trapezoidal block 17.

[0033] In this embodiment, when installing the new detection probe 5, first insert the installation block 4 into the installation groove 3. At the same time, the installation block 4 drives the trapezoidal block 17 to move, so that the trapezoidal block 17 slides into the limiting cavity 16, and then the clamping block 18 is clamped in the clamping groove of the trapezoidal block 17 to limit the trapezoidal block 17. At the same time, the installation block 4 is fixed in the installation groove 3. After that, the installation mechanism can be operated to fix the installation block 4. Through the sliding fit between the trapezoidal block 17 and the limiting cavity 16 and the clamping action of the clamping block 18, the stable positioning of the installation block 4 is realized, which is convenient for the subsequent operation of the installation mechanism to install the installation block 4.

[0034] In a further preferred embodiment of the present utility model, a sliding groove is opened on one side of the limiting cavity 16. A connecting rod 19 is slidably arranged in the sliding groove. One end of the connecting rod 19 is fixedly connected to the clamping block 18. A connecting spring 20 is sleeved on the connecting rod 19. Two ends of the connecting spring 20 are respectively fixedly connected to the clamping block 18 and the limiting cavity 16.

[0035] In this embodiment, the addition of the connecting spring 20 provides a stable reset force for the clamping block 18, ensuring that the clamping block 18 can accurately reset to the initial position after each operation, improving the reliability and stability of the device. Through the cooperation of the connecting rod 19 and the connecting spring 20, the sliding operation of the clamping block 18 is made simpler and more intuitive, reducing the operation difficulty and complexity.

[0036] In a further preferred embodiment of the present utility model, an L-shaped cavity is opened at the top of the support plate 1. The L-shaped cavity is communicated with the limiting cavity 16. A pull rope 21 is installed on one side of the clamping block 18. The pull rope 21 extends out of the support plate 1 through the L-shaped cavity. A pull ring is installed at one end of the pull rope 21.

[0037] In this embodiment, through the design of the pull rope 21 and the pull ring, the user can realize the sliding operation of the clamping block 18 without directly contacting the clamping block 18 or using complex tools, greatly improving the operation convenience and efficiency.

[0038] To sum up, compared with the related technology, the present device can automatically detect the liquid injection hole, avoid misjudgment and missed detection caused by human factors, and ensure that the quality of the light aluminum sheet of the lithium battery cover meets the standard.
