Description

Technical Field

[0001] This invention belongs to the field of battery testing technology, specifically a battery plate testing device. Background Technology

[0002] A lead-acid battery mainly consists of positive and negative plates, separators, a safety valve, a battery case, a middle cover, and electrolyte. The positive and negative plates are primarily lead alloy grids, which are loaded with active material. The lead alloy grids are a crucial component of the battery, accounting for 20% to 30% of its total weight.

[0003] In lead-acid batteries, lead alloy grids serve as a carrier for lead paste (active material). The lead paste is supported and distributed by the grids. After the lead paste is distributed and fixed on the grids, it becomes an electrode plate. The electrode plate needs to be tested to observe the distribution of lead paste on the grids.

[0004] Chinese invention patent CN117019652A discloses an integrated device for testing and sorting lead-acid battery plates, belonging to the technical field of lead-acid battery plate production equipment. It includes a testing device, a sorting device, a conveyor belt mechanism, and a control device. The testing device comprises a testing platform, a weighing component, and a vision component. The testing platform is fixed relative to the ground, and the vision and weighing components are mounted on the testing platform with their centers perpendicularly aligned, allowing for simultaneous visual and weighing testing of the plates. The sorting device includes a rotating device and four sets of support rollers. The rotating device is mounted on the testing platform and is horizontally aligned with the vision component. The four sets of powered support rollers are installed on the four sides of the rotating device, enabling it to transport the plates supported by the support rollers to the testing area. After the testing process, the rotating device rotates the plates to the corresponding conveyor belt mechanism. The conveyor belt mechanism includes a first conveyor belt mechanism for collecting qualified products and a second conveyor belt mechanism for collecting unqualified products. Both conveyor belt mechanisms are fixed relative to the ground and positioned perpendicularly to the rotating device at 90° angles. The control device is mounted on the testing platform.

[0005] The aforementioned technologies suffer from incomplete testing. Summary of the Invention

[0006] The purpose of this invention is to provide a battery plate detection device to solve at least one of the above-mentioned technical problems.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0008] A battery plate testing device, comprising:

[0009] A transparent testing stage, along the conveying direction, has a length less than the length of the electrode plate;

[0010] The detection component includes an analysis module and a pair of detection cameras connected to the analysis module. The pair of detection cameras are respectively disposed on the upper and lower sides of the transparent detection stage. The detection cameras are used to capture images of the corresponding side of the electrode plate and transmit the captured images to the analysis module. The analysis module performs analysis and detection based on the captured images.

[0011] The production line includes a first section and a second section, which are located at opposite ends of the transparent inspection station along the conveying direction.

[0012] This invention sets the testing platform as a transparent testing platform, with testing cameras installed on both the top and bottom sides of the transparent testing platform to achieve appearance inspection of both the front and back of the electrode plate, resulting in a more comprehensive inspection. The first section of the set assembly line is used to transport the electrode plate to the transparent testing platform. Since the length of the transparent testing platform is less than the length of the electrode plate, after the electrode plate is separated from the first section, part of it has already been transported to the second section. The second section drives the electrode plate to continue moving and transport the electrode plate away.

[0013] Furthermore, the pair of detection cameras are staggered along the conveying direction to avoid the pair of detection cameras becoming backgrounds to each other and affecting the detection effect.

[0014] Furthermore, a bellows is provided above the transparent testing platform, with an air outlet at the bottom of the side wall of the bellows. A nozzle corresponding to the air outlet is provided on the outer wall of the bellows, facing the testing area corresponding to the testing camera located below the transparent testing platform and away from the testing camera located above the transparent testing platform. A compressed air pipe is connected to the top of the bellows. Some defective plates may have lead paste powder falling onto the transparent testing platform, which could obstruct the testing camera located below the platform and affect the testing effect on the bottom surface of the plates. By connecting the bellows to the compressed air pipe, and with the air outlet and nozzles on the bellows, the lead paste powder on the transparent testing platform and in the testing area corresponding to the testing camera located below the transparent testing platform can be blown away, preventing it from obstructing the testing camera and affecting the testing.

[0015] Furthermore, a wind baffle assembly is slidably connected inside the air box, and the top of the air box is also connected to the wind baffle assembly via a tension spring. The wind baffle assembly includes a horizontally arranged wind-facing plate and a vertically arranged wind-blocking plate, with the wind-facing plate fixedly connected to the wind-blocking plate. A through groove is provided on the bottom surface of the air box for the wind-blocking plate to extend out of the air box. The detection camera located above the transparent detection platform and the air outlet are respectively located on both sides of the wind baffle plate. When the air box above the transparent detection platform blows away the lead paste powder, the lead paste powder is blown into the air and easily adheres to the detection camera located above the transparent detection platform, affecting the detection effect. This invention, by setting up a wind baffle assembly, when the compressed air pipeline is closed, pulls... A spring pulls the wind deflector assembly in place. The air outlet is located below the windward plate, and the wind deflector assembly blocks the air outlet from the compressed air pipe. When the compressed air pipe is opened, the compressed airflow impacts the windward plate, pushing it downward and causing the wind deflector to descend as well. The wind deflector then comes into contact with the transparent inspection platform. After the windward plate descends, the air outlet is located above it and is connected to the compressed air pipe. Compressed air is blown out from the air outlet. At this time, the descending wind deflector separates the air outlet from the inspection camera located above the transparent inspection platform, preventing the airflow from carrying lead paste powder to the inspection camera, thus making it difficult for the lead paste powder to adhere to the lens of the inspection camera.

[0016] Furthermore, a buffer strip is provided at the bottom of the wind deflector to provide cushioning when the wind deflector comes into contact with the transparent testing platform, thus protecting the transparent testing platform and the wind deflector.

[0017] Furthermore, the transparent detection stage is provided with background plates on both sides, each corresponding to one of the pair of detection cameras, to improve the detection effect.

[0018] Furthermore, a mounting plate is provided between the detection camera and its corresponding detection area. An arched lampshade is provided on the side of the mounting plate near the detection camera. Light-transmitting slits corresponding to the detection camera are opened on both the mounting plate and the lampshade. Symmetrical strip light sources are provided on the mounting plate along the light-transmitting slits. By setting the strip light sources, the supplementary lighting at the detection camera is made uniform, which is beneficial to improving the detection effect. The arched lampshade diffuses the light, making the light softer and more uniform.

[0019] Furthermore, it also includes a vacuum cleaner, the nozzle of which is connected to a dust collector hood, which faces the nozzle. The detection area of ​​the detection camera located below the transparent detection platform is located between the dust collector hood and the nozzle. By setting up a vacuum cleaner in conjunction with a bellows, the lead paste powder blown up by the nozzle on the bellows can be sucked away, avoiding lead paste powder pollution of the environment. The dust collector hood helps to improve the effect of sucking up lead paste powder.

[0020] The present invention also includes a feeding assembly for feeding defective electrode plates.

[0021] Specifically, the feeding assembly includes a cylinder and a material frame respectively disposed on both sides of the second section. The telescopic rod of the cylinder is provided with a push plate for pushing the electrode plate. The cylinder and the push plate are used to push the unqualified electrode plate into the material frame.

[0022] Compared with the prior art, the beneficial effects of the present invention are:

[0023] (1) By setting the testing platform as a transparent testing platform, and setting testing cameras on both the upper and lower sides of the transparent testing platform, the present invention can perform appearance inspection on the electrode plate from both the front and back to determine whether the lead paste application is qualified, and the inspection is more comprehensive. The first section of the set assembly line is used to transport the electrode plate to the transparent testing platform. Since the length of the transparent testing platform is less than the length of the electrode plate, after the electrode plate is separated from the contact with the first section, part of it has been transported to the second section. The second section drives the electrode plate to continue to move and transport the electrode plate away.

[0024] (2) When a bellows is set above the transparent testing platform to blow away lead paste powder, the lead paste powder is blown into the air and easily sticks to the testing camera located above the transparent testing platform, affecting the testing effect. The present invention sets up a wind deflector component. When the compressed air pipeline is closed, the tension spring pulls the wind deflector component, and the air outlet is located below the windward plate. The wind deflector component blocks the air outlet and the compressed air pipeline. When the compressed air pipeline is opened, the compressed airflow impacts the windward plate and pushes the windward plate to slide down, thereby driving the wind deflector plate down together. After the windward plate is down, the air outlet is located above the windward plate. The air outlet is connected to the compressed air pipeline, and compressed air is blown out from the air outlet. At this time, the wind deflector plate after falling separates the air outlet from the testing camera located above the transparent testing platform, preventing the airflow from carrying lead paste powder to this testing camera, so that the lead paste powder is difficult to stick to the lens of this testing camera.

[0030] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are merely some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] like Figure 1 and Figure 2 As shown, this embodiment provides a battery plate testing device, including a transparent testing stage 1, a testing component 3, a production line 4, and a feeding component 5.

[0032] Along the conveying direction, the length of the transparent detection stage 1 is less than the length of the electrode plate 2.

[0033] The detection component 3 includes an analysis module and a pair of detection cameras 301 connected to the analysis module. The pair of detection cameras 301 are respectively disposed on the upper and lower sides of the transparent detection stage 1. The detection cameras 301 are used to capture images of the corresponding sides of the electrode plate 2 and transmit the captured images to the analysis module. The analysis module performs analysis and detection based on the captured images. Preferably, the detection camera 301 can be a line scan camera. The detection camera 301 located above the transparent detection stage 1 is defined as the first detection camera, and the detection camera 301 located below the transparent detection stage 1 is defined as the second detection camera.

[0034] The production line 4 includes a first section 401 and a second section 402, which are located at the two ends of the transparent inspection station 1 along the conveying direction.

[0035] The feeding assembly 5 is used to feed the defective electrode plate 2. In one possible implementation, the feeding assembly 5 includes a cylinder 501 and a material frame 502 respectively disposed on both sides of the second section 402. The telescopic rod of the cylinder 501 is provided with a push plate 503 for pushing the electrode plate 2. The cylinder 501 and the push plate 503 are used to push the defective electrode plate 2 into the material frame 502.

[0036] This invention sets the testing platform as a transparent testing platform 1, and sets testing cameras 301 on both the upper and lower sides of the transparent testing platform 1 to realize the appearance inspection of both the front and back of the electrode plate 2, so as to make the inspection more comprehensive. The first section 401 of the set assembly line 4 is used to transport the electrode plate 2 to the transparent testing platform 1. Since the length of the transparent testing platform 1 is less than the length of the electrode plate 2, after the electrode plate 2 is separated from the contact of the first section 401, part of it has been transported to the second section 402. The second section 402 drives the electrode plate 2 to continue to move and transport the electrode plate 2 away.

[0037] Furthermore, the pair of detection cameras 301 are staggered along the conveying direction to avoid the pair of detection cameras 301 becoming backgrounds to each other and affecting the detection effect.

[0038] Furthermore, a bellows 6 is provided above the transparent testing platform 1, located between the first and second testing cameras. An air outlet is provided at the bottom of the side wall of the bellows 6. Preferably, the air outlet is located on the side of the bellows 6 facing away from the first testing camera. A nozzle 7 corresponding to the air outlet is provided on the outer wall of the bellows 6. The nozzle 7 faces the testing area corresponding to the testing camera 301 located below the transparent testing platform 1 and faces away from the testing camera 301 located above the transparent testing platform 1; that is, the nozzle 7 faces the testing area corresponding to the second testing camera and faces away from the first testing camera. A compressed air pipe 8 is connected to the top of the bellows 6. Some defective electrode plates 2 may have lead paste powder falling onto the transparent testing platform 1, which may obstruct the second testing camera and affect the testing effect on the bottom surface of the electrode plate 2. By connecting the bellows 6 to the compressed air pipe 8, and with the air outlet and nozzle 7 on the bellows 6, the lead paste powder on the testing area corresponding to the second testing camera on the transparent testing platform 1 can be blown away, preventing it from obstructing the testing camera 301 and affecting the testing.

[0039] Furthermore, a wind baffle assembly 9 is slidably connected inside the air box 6, and the top of the air box 6 is also connected to the wind baffle assembly 9 via a tension spring 10. The wind baffle assembly 9 includes a horizontally arranged wind-facing plate 901 and a vertically arranged wind baffle plate 902. The wind-facing plate 901 and the wind baffle plate 902 are fixedly connected. Optionally, the tension spring 10 can connect the wind baffle plate 902 to the top of the air box 6. Alternatively, the tension spring 10 can also connect the wind-facing plate 901 to the top of the air box 6. The bottom surface of the air box 6 has a through groove for the wind baffle plate 902 to extend out of the air box 6. The first detection camera and the air outlet are located on both sides of the wind baffle plate 902. When the air box 6 is set above the transparent detection platform 1 to blow away the lead paste powder, the lead paste powder is blown into the air and easily sticks to the detection camera 301 located above the transparent detection platform 1. That is, the lead paste powder easily sticks to the first detection camera, affecting the detection effect. Figure 3 and Figure 4As shown, when the compressed air pipe 8 is closed, the tension spring 10 pulls the wind deflector 9, and the air outlet is located below the windproof plate 901. The wind deflector 9 blocks the air outlet from the compressed air pipe 8. When the compressed air pipe 8 is opened, the compressed airflow impacts the windproof plate 901, pushing it downwards, thereby causing the wind deflector 902 to descend as well. The wind deflector 902 abuts against the transparent detection platform 1. After the windproof plate 901 descends, the air outlet is located above it and is connected to the compressed air pipe 8. Compressed air is blown out from the air outlet. After the baffle plate 902 descends, it separates the air outlet from the detection camera 301 located above the transparent detection platform 1. That is, the baffle plate 902 separates the air outlet from the first detection camera, preventing the airflow from carrying lead paste powder to the first detection camera, thus making it difficult for the lead paste powder to stick to the lens of the first detection camera. Since the baffle plate 902 will come into contact with the transparent detection platform 1 when the compressed air pipeline 8 is opened, blocking the electrode plate 2 from moving forward, the compressed air pipeline 8 should be opened intermittently. For example, it can be opened for a few seconds between multiple electrode plate 2 detections to blow away the lead paste powder, or it can be opened when the production line 4 stops.

[0040] Furthermore, the bottom of the wind deflector 902 is provided with a buffer strip 11 to provide buffer when the wind deflector 902 comes into contact with the transparent inspection table 1, thereby protecting the transparent inspection table 1 and the wind deflector 902.

[0041] Furthermore, the transparent detection stage 1 is provided with background plates 12 on both sides, which correspond one-to-one with the pair of detection cameras 301, in order to improve the detection effect.

[0042] Furthermore, a mounting plate 13 is provided between the detection camera 301 and its corresponding detection area. An arched lampshade 14 is provided on the side of the mounting plate 13 near the detection camera 301. Light-transmitting slits corresponding to the detection camera 301 are provided on both the mounting plate 13 and the lampshade 14. Symmetrical strip light sources are provided on the mounting plate 13 along the light-transmitting slits. By setting the strip light sources, the supplementary lighting at the detection camera 301 is uniform, which is beneficial to improving the detection effect. The arched lampshade 14 diffuses the light, making the light softer and more uniform.

[0043] Furthermore, it also includes a vacuum cleaner 15, the nozzle of which is connected to a concentrator 16, the concentrator 16 facing the nozzle 7; the detection area corresponding to the second detection camera is located between the concentrator 16 and the nozzle 7. By setting the vacuum cleaner 15 in conjunction with the air box 6, the lead paste powder blown by the nozzle 7 on the air box 6 can be sucked away, avoiding lead paste powder from polluting the environment. The concentrator 16 is designed to improve the effect of sucking up lead paste powder.

[0044] It should be noted that although the present invention has been disclosed above with specific embodiments, the above embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
