Description

Technical Field

[0001] The present invention relates to the technical field of lithium battery detection, and in particular to a rapid detection device for lithium battery outer packaging based on visual detection. Background Art

[0002] In the port cargo management process, cargo quality inspection is a key step in ensuring smooth trade, maintaining market order, and safeguarding consumer rights. Currently, port cargo sampling, inspection, and laboratory testing face numerous challenges.

[0003] During the random inspection process, cargo samples are primarily selected manually. However, manual inspections have significant shortcomings. First, they are slow, making them difficult to complete quickly in ports with large cargo throughput, impacting cargo flow efficiency and increasing port operating costs. Second, manual inspections are susceptible to subjective factors, with different inspectors having varying understandings and implementation of inspection standards. This makes it difficult to ensure the scientific and impartial nature of the inspections, potentially overlooking goods with quality issues and allowing substandard products to enter the market.

[0004] The existing testing process lacked efficient information management, leading to confusion and delays in sample transportation and delivery. During the transportation of cargo samples from the port to the laboratory, information was not recorded promptly and accurately, making it impossible to track the location and status of the samples in real time. This prevented the laboratory from conducting testing in a timely manner, impacting the entire testing cycle.

[0005] In the laboratory testing process, traditional testing equipment and methods need to improve their efficiency and accuracy when dealing with increasingly diverse and complex goods. Some testing equipment has a low degree of automation and requires extensive manual operation. This not only increases the workload for testers but also easily introduces errors during operation, affecting the reliability of test results. Furthermore, testing standards and methods vary among laboratories, and a lack of unified standards makes test results less comparable, complicating comprehensive assessments of goods quality.

[0006] With the continuous development of information technology and testing technologies, the use of advanced technologies to optimize port cargo inspection processes has become an inevitable trend. However, some existing inspection-assisted equipment and systems, when applied to port cargo inspection, suffer from poor coordination between the capture, transportation, and testing of cargo samples, failing to meet the requirements for efficient and accurate testing. For example, when capturing cargo samples, the gripping device lacks stability and reliability, which can easily lead to sample damage or drop. During sample transportation, a lack of effective protection and positioning measures compromises sample integrity and the accuracy of test results. Summary of the Invention

DETAILED DESCRIPTION

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "connect," "fixed," etc. should be understood broadly. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0025] Example 1: In order to solve the problem that the clamping effect of lithium batteries in the prior art is poor and dust on the surface of lithium batteries will affect the clamping effect, please refer to Figures 1-8 , the present invention provides a technical solution: A rapid inspection device for lithium battery outer packaging based on visual inspection includes a frame 1 and a detection platform 2 fixedly installed on the top of the frame 1. A display screen 5 is fixedly installed on the back of the detection platform 2, and the display screen 5 is electrically connected to the camera 1 206. An electric control switch 7 is fixedly installed on the left front of the detection platform 2, and the electric control switch 7 is electrically connected to the camera 1 206 and the display screen 5. A control panel 8 is slidably connected to the inside of the frame 1, and the camera 2 303 is electrically connected to the electric control switch 7 and the display screen 5.

[0026] The back of the detection platform 2 is fixedly connected to a base 6, and the top of the base 6 is fixedly connected to a grabbing robot arm 601. The end of the grabbing robot arm 601 away from the base 6 is fixedly connected to a motor 1 602. The output end of the motor 1 602 is connected to a rotating frame 603. One side of the rotating frame 603 is fixedly connected to a motor 2 604. The output end of the motor 2 604 is connected to a transmission structure 605. One side of the transmission structure 605 is rotatably connected to a clamping plate 606. A movable chamber 1 6061 is provided inside the clamping plate 606, and a movable chamber 2 6062 is also provided inside the clamping plate 606. A slide 6067 is provided on the inner wall of the movable chamber 1 6061. A clamping block 1 6063 is slidably connected to the interior of the movable chamber 1 6061. An air channel 6064 is provided inside the clamping block 1 6063. A suction cup 6065 is fixedly connected to the side of the clamping block 1 6063 away from the inner wall of the movable chamber 1 6061. A slider 6066 is slidably connected to the interior of the slide 6067. A telescopic spring 6068 is fixedly connected to the inner wall of the movable chamber 1 6061. The suction cup 6065 connects the outside with the inside of the movable chamber 1 6061 through the air channel 6064. The slider 6066 and the telescopic spring 6068 are both fixedly connected to one side of the clamping block 1 6063. A connecting air channel 6069 is provided inside the clamping plate 606.

[0027] When clamping qualified lithium batteries, the output shaft of motor 1 602 first drives the rotating frame 603 to rotate, thereby driving the overall rotation angle of the grabbing robot arm 601. Secondly, the output shaft of motor 2 604 drives the transmission structure 605 to rotate, thereby adjusting the angle of the two clamping plates 606 to facilitate clamping of the lithium battery.

[0028] When the two clamping plates 606 contact the outside of the lithium battery, the outside of the lithium battery will first squeeze the clamping block 1 6063. At this time, the clamping block 1 6063 will slide inside the active chamber 1 6061 and push the slider 6066 to slide inside the slide 6067, thereby pushing the air in the slide 6067 to the inside of the connecting air channel 6069, and then ejected from the inside of the active chamber 2 6062. The ejected airflow will impact the outer surface of the lithium battery, flushing away the dust and preventing the dust from adhering to the surface of the lithium battery. The air inside the active chamber 6061 will enter the inside of the air channel 6064 and then ejected from the gap of the suction cup 6065, impacting the outer surface of the lithium battery again, flushing away the dust, increasing the friction force on the outer surface of the lithium battery, and thus improving the clamping effect on the lithium battery. At the same time, after the gas is discharged, the suction cup 6065 will be adsorbed on the outer surface of the lithium battery, thereby enhancing the adsorption force on the lithium battery and improving the clamping effect.

[0029] After the clamping is completed, the two clamping plates 606 release the lithium battery, and one side of the clamping block 6063 loses the squeezing force. Under the action of the restoring force of the telescopic spring 6068 itself, the clamping block 6063 is pushed to reset, and the outside air enters the interior of the active cavity 6061, so that the clamping block 6063 maintains the clamping effect.

[0030] The left side of the testing platform 2 is provided with a feed conveyor belt 3, the bottom of which is fixedly mounted a bracket 301. The right side of the testing platform 2 is provided with a discharge conveyor belt 4, the bottom of which is fixedly mounted a bracket 401, and the top of which is provided with a limit plate 402. Both the feed conveyor belt 3 and the discharge conveyor belt 4 are driven by a simple synchronous belt mechanism. The top of the detection platform 2 is fixedly connected to a slide rail 1 201, the outer surface of the slide rail 1 201 is slidably connected to a slide rail 202, the left side of the slide rail 202 is slidably connected to a sliding frame 203, the left side of the front of the sliding frame 203 is fixedly connected to a mounting frame 1 204, the front of the mounting frame 1 204 is fixedly connected to a buckle 205, and the buckle 205 is snapped into the camera 1 206.

[0031] Example 2: In order to further enhance the adsorption and clamping effect of lithium batteries and at the same time further enhance the removal of dust, the present application has a clamping block 60611 slidingly connected to the interior of the active cavity 6062, a fixed magnetic block 60610 fixedly connected to the interior of the clamping plate 606, and a movable magnetic block 60612 fixedly connected to the interior of the clamping block 60611. The slide 6067 is connected to the interior of the active cavity 6062 through the connecting air channel 6069, and the fixed magnetic block 60610 and the movable magnetic block 60612 are attracted to each other on their close sides.

[0032] During the sliding process of the clamping block 1 6063, the gas inside the active chamber 1 6061 will enter the connecting air channel 6069 from the inside of the slide 6067, and then enter the inside of the active chamber 2 6062. The airflow pushes the clamping block 2 60611, overcoming the attraction between the fixed magnetic block 60610 and the movable magnetic block 60612. The discharged gas pushes the clamping block 2 60611 to move, so that the clamping block 1 6063 and the clamping block 2 60611 clamp the lithium battery at the same time, further enhancing the clamping effect.

[0033] After the extrusion force of the lithium battery is lost, under the attraction of the fixed magnetic block 60610 to the movable magnetic block 60612, the clamping block 60611 will slide and reset inside the movable cavity 6062, thereby facilitating the next clamping.

[0034] Example 3: In order to pre-inspect the packaging of lithium batteries, exclude some batteries with too great differences in appearance, and reduce the difficulty of inspection on the inspection platform 2, the present application has a mounting frame 2 302 fixedly installed on the top of the bracket 1 301, a camera 2 303 fixedly installed on the left side of the mounting frame 2 302, a cylinder 1 304 and a cylinder 2 307 fixedly installed on the back of the bracket 1 301, the output end of the cylinder 1 304 is connected to the telescopic rod 305, the side of the telescopic rod 305 is fixedly connected to the toggle plate 306, the output end of the cylinder 2 307 is connected to the lifting frame 308, the front of the lifting frame 308 is fixedly connected to the pressure plate 309, and the back of the bracket 1 301 is fixedly installed with a waste box 310.

[0035] When the lithium battery passes through the feed conveyor belt 3, it will first be photographed by the camera 2 303, and the photographed image will be transmitted to the display screen 5. When a lithium battery with obvious damage or a large difference in appearance is detected, the cylinder 1 304 is started, the output end of the cylinder 1 304 contracts, and the telescopic rod 305 is pulled. The telescopic rod 305 pulls the toggle plate 306 to move, and during the movement, the damaged lithium battery is pushed into the interior of the waste box 310, thereby realizing the pre-detection of the lithium battery and reducing the detection pressure on the detection platform 2.

[0036] Working principle: When inspecting the outer packaging of lithium batteries, first measure the lithium batteries and place them on the feed conveyor belt 3, and transfer them to the inspection platform 2 through the feed conveyor belt 3. Move the camera 1 206 to drive the mounting frame 1 204 and the sliding frame 203 to slide on the surface of the slide rail 2 202, adjust the position of the camera 1 206, and then push the slide rail 2 202 to slide on the surface of the slide rail 1 201, further adjust the position of the camera 1 206, and transmit the image of the lithium battery outer packaging taken by the camera 1 206 to the display screen 5. The display screen 5 is used to determine whether the lithium battery outer packaging is damaged. After the damaged ones are removed, the qualified lithium batteries will be picked up by the grabbing robot arm and placed on the discharge conveyor belt 4 for transportation.
