Description

Technical Field

[0002] Lithium-ion battery: It is a secondary battery (rechargeable battery), commonly known as a lithium battery. It mainly works by the movement of lithium ions between the positive and negative electrodes. When producing lithium batteries, a visual detection device is required to detect the full size of the lithium batteries to ensure the ex-factory quality of the lithium batteries and avoid defective products leaving the factory. The visual detection device uses a machine to replace the human eye for measurement and judgment. Visual detection refers to converting the captured target into an image signal through machine vision products (such as industrial cameras, etc.), transmitting it to a dedicated image processing system, and converting it into a digital signal according to information such as pixel distribution, brightness, and color; the image system performs various operations on these signals to extract the features of the target, and then discriminates the product quality.

[0003] When the existing measurement mechanism is measuring, it is necessary to clamp and fix the lithium battery. However, since it is inconvenient to detect the thickness of the lithium battery when it is clamped by the fixture, the accuracy of the lithium battery size measurement is affected. Summary of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0030] The following is a further detailed description of this application in combination with the attached Figures 1-5 drawings.

[0031] Please refer to Figures 1-3, A vision detection and size measurement mechanism for a lithium battery, including a detection box 1 and a detection mechanism 5 installed inside the detection box 1. A CCD vision detector 4 is fixedly connected to the inner wall of the top of the detection box 1, and the CCD vision detector 4 is located directly above the detection mechanism 5. The detection mechanism 5 includes a measurement box 6 fixedly connected to the inner wall of the bottom of the detection box 1, and a U-shaped seat 7 is fixedly connected to the inner wall of the bottom of the measurement box 6. Two symmetrically arranged electric slide rails 8 are provided on the inner wall of the bottom of the measurement box 6, and detection components 9 for detecting the thickness of the lithium battery are provided on both of the two electric slide rails 8.

[0032] During use, by setting the detection mechanism 5 in the detection box 1, it is convenient to fixedly detect the lithium battery. The CCD vision detector 4 can detect the appearance of the lithium battery. The U-shaped seat 7 provided in the measurement box 6 is convenient for auxiliary fixation of the lithium battery. The setting of the electric slide rail 8 is convenient for driving the movement of the detection component 9. When the detection component 9 moves, it directly detects the thickness at multiple positions of the lithium battery.

[0033] Refer to Figure 4 , The detection component 9 includes a support seat 12 slidably connected to the electric slide rail 8, and a sliding frame 14 is slidably connected to the outer wall of the support seat 12. The setting of the electric slide rail 8 is convenient for directly driving the movement of the support seat 12, and the sliding frame 14 can be slidably adjusted on the support seat 12.

[0034] Refer to Figure 4 , A distance measuring sensor 16 is fixedly connected to the outer wall of one side of the sliding frame 14, a driving component 15 is installed on the inner wall of the sliding frame 14, an electric slide rail 13 is fixedly connected to the outer wall of one side of the support seat 12, and the sliding frame 14 is slidably connected to the electric slide rail 13. The setting of the distance measuring sensor 16 is convenient for directly detecting the thickness of the lithium battery. The setting of the electric slide rail 13 is convenient for adjusting the position of the sliding frame 14, thereby facilitating the adjustment of the position of the distance measuring sensor 16.

[0035] Refer to Figures 4-5 , The driving component 15 includes a driving tube 17 fixedly connected to the sliding frame 14, and a driving column 20 is slidably connected to the inner wall of the driving tube 17. A rubber protrusion 21 in contact with the lithium battery is fixedly connected to the outer wall of the bottom of the driving column 20. By directly contacting the lithium battery with the rubber protrusion 21 on the driving column 20, it is convenient to protect the surface of the lithium battery. The setting of the driving tube 17 is convenient for slidably installing the driving column 20.

[0036] Refer to Figure 5 , A contact switch 18 is fixedly connected to the inner wall of the top of the driving tube 17, and the contact switch 18 and the driving column 20 are fixedly connected by the same spring 19. When the spring 19 in the driving tube 17 is compressed, it directly triggers the contact switch 18, thereby facilitating the activation of the distance measuring sensor 16 and the stop of the electric slide rail 13.

[0037] Referring to Figure 3 , two rectangular openings for installing the first electric slide rail 8 are formed in the inner wall of the bottom of the measuring box 6, and the second electric slide rails 10 are fixedly connected to the outer walls on both sides of the measuring box 6. The formation of the rectangular openings facilitates the concealed installation of the first electric slide rail 8, thereby preventing the protrusion of the first electric slide rail 8 from affecting the detection of the battery thickness.

[0038] Referring to Figure 3 , a pressing seat 11 is slidably connected to the inner wall of the measuring box 6, and the pressing seat 11 is slidably connected to the two second electric slide rails 10. The arrangement of the second electric slide rails 10 facilitates the adjustment of the position of the pressing seat 11, thereby facilitating the pressing of the lithium battery.

[0039] Referring to Figure 1 , two box doors 2 are hinged to the outer wall of one side of the detection box 1, and a control panel 3 is fixedly connected to the outer wall of one side of the detection box 1, and the control panel 3 is electrically connected to the CCD vision detector 4, the first electric slide rail 8, the second electric slide rails 10, the third electric slide rail 13, the ranging sensor 16 and the contact switch 18. The arrangement of the control panel 3 facilitates the control of the electrical components in the measuring device.

[0040] The implementation principle of this application is as follows: During use, the lithium battery to be detected is placed on the measuring box 6. At the same time, the second electric slide rail 10 is activated to directly drive the pressing seat 11 to move. When the pressing seat 11 moves towards the U-shaped seat 7, the lithium battery is directly pressed. After the lithium battery is pressed, the CCD vision detector 4 directly detects the appearance of the lithium battery. When it is necessary to detect the thickness of the lithium battery, the third electric slide rail 13 directly drives the sliding frame 14 to move downward. When the sliding frame 14 moves downward, the rubber protrusion 21 in the driving assembly 15 contacts the lithium battery. At this time, the driving column 20 compresses the spring 19. When the spring 19 is compressed, the contact switch 18 is directly triggered. When the contact switch 18 is triggered, the third electric slide rail 13 stops operating. At this time, the ranging sensor 16 detects the thickness of the lithium battery. The arrangement of the first electric slide rail 8 facilitates the driving of the support seat 12 to move, and by adjusting the position of the support seat 12, it is convenient to detect the thickness of multiple positions of the lithium battery.

[0041] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
