[0005] Regarding the above-mentioned related technologies, there is a problem of incomplete detection. Summary of the invention

[0006] The object of the present invention is to provide a battery plate detection device to solve at least one of the above technical problems.

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

[0008] A battery plate detection device, comprising:

[0009] A transparent detection platform, wherein the length of the transparent detection platform is smaller than the length of the electrode plate along the conveying direction;

[0010] A detection component, comprising an analysis module and a pair of detection cameras respectively connected to the analysis module, wherein the pair of detection cameras are respectively arranged on the upper and lower sides of the transparent detection platform, wherein the detection cameras are respectively used to capture images of the corresponding sides of the electrode plates and transmit the captured images to the analysis module, and the analysis module performs analysis and detection according to the captured images;

[0011] The production line comprises a first section and a second section, wherein the first section and the second section are respectively located at two ends of the transparent detection platform along the conveying direction.

[0012] The present invention sets the inspection platform as a transparent inspection platform, and sets inspection cameras on both the upper and lower sides of the transparent inspection platform, so as to realize the appearance inspection of the front and back sides of the electrode plate, and the inspection is more comprehensive; the first section of the set assembly line is used to transport the electrode plate to the transparent inspection platform. Because the length of the transparent inspection 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, and the second section drives the electrode plate to continue to move, so as to 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 serving as each other's background and affecting the detection effect.

[0014] Furthermore, a bellows is provided above the transparent detection platform, an air outlet is provided at the bottom of the side wall of the bellows, and an air nozzle corresponding to the air outlet is provided on the outer wall of the bellows, the air nozzle faces the detection area corresponding to the detection camera located below the transparent detection platform, and is away from the detection camera located above the transparent detection platform, and the top of the bellows is connected to a compressed air pipe; lead paste powder of some unqualified plates will fall onto the transparent detection platform, which will block the detection camera located below the transparent detection platform and affect the detection effect of the bottom surface of the plate. The bellows is connected to the compressed air pipe by the arrangement, and the air outlet and the air nozzle provided on the bellows can be used to blow away the lead paste powder on the detection area corresponding to the detection camera located below the transparent detection platform, so as to avoid blocking the detection camera and affecting the detection.

[0015] Furthermore, a windshield assembly is slidably connected inside the bellows, and the top of the bellows is also connected to the windshield assembly by a tension spring, and the windshield assembly includes a horizontally arranged windward plate and a vertically arranged windshield plate, the windward plate is fixedly connected to the windshield plate, and a through groove is provided on the bottom surface of the bellows for the windshield plate to extend out of the bellows; the detection camera and the air outlet located above the transparent detection platform are respectively located on both sides of the windshield plate; when a bellows is set above the transparent detection platform to blow away the lead paste powder, the lead paste powder is blown into the air and is easily stained on the detection camera located above the transparent detection platform, thereby affecting the detection effect; the present invention sets a windshield assembly, and when the compressed air pipeline is closed, the tension spring is pulled The spring pulls the wind shield assembly, and the air outlet is located below the windward plate. The wind shield assembly blocks the air outlet and the compressed air duct; when the compressed air duct is opened, the compressed air flow hits the windward plate, pushing the windward plate to slide downward, thereby driving the wind shield to descend together, and the wind shield abuts against the transparent detection platform. After the windward plate descends, the air outlet is located above the windward plate, and the air outlet is connected to the compressed air duct, and compressed air is blown out from the air outlet. At this time, the descended wind shield separates the air outlet from the detection camera located above the transparent detection platform, preventing the airflow from carrying the lead paste powder to flow to the detection camera, thereby making it difficult for the lead paste powder to stick to the lens of the detection camera.

[0016] Furthermore, a buffer strip is provided at the bottom of the windshield to provide a buffer when the windshield contacts the transparent detection platform, thereby protecting the transparent detection platform and the windshield.

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

[0018] Furthermore, a mounting plate is provided between the detection camera and its corresponding detection area, and an arched lampshade is provided on the side of the mounting plate close to the detection camera. The mounting plate and the lampshade are both provided with light-transmitting slits corresponding to the detection camera, and symmetrical strip light sources are provided on the mounting plate along the light-transmitting slits. By providing the strip light sources, the fill light at the detection camera is uniform, which is beneficial to improving the detection effect. The arched lampshade diffusely reflects the light, making the light softer and more uniform.

[0019] Furthermore, it also includes a vacuum cleaner, the suction nozzle of the vacuum cleaner is connected to an air collecting hood, and the air collecting hood faces the air nozzle; the detection area corresponding to the detection camera located below the transparent detection platform is located between the air collecting hood and the air nozzle, and by arranging the vacuum cleaner in conjunction with the bellows, the lead paste powder blown up by the air nozzle on the bellows can be sucked away to avoid the lead paste powder from polluting the environment. The setting of the air collecting hood is beneficial to improving the effect of sucking the lead paste powder.

The cylinder cooperates with the push plate to push the unqualified electrode plate to the material frame.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] (1) The present invention sets the inspection platform as a transparent inspection platform, and sets inspection cameras on both the upper and lower sides of the transparent inspection platform, so as to perform appearance inspection on the electrode plate from both sides, judge whether the lead paste coating is qualified, and make the inspection more comprehensive; the first section of the set assembly line is used to transport the electrode plate to the transparent inspection platform. Because the length of the transparent inspection 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, and the second section drives the electrode plate to continue to move and transport the electrode plate away.

[0024] (2) When a bellows is provided above the transparent detection platform to blow away the lead paste powder, the lead paste powder is blown into the air and is easily attached to the detection camera located above the transparent detection platform, thus affecting the detection effect. The present invention provides a wind shield assembly. When the compressed air pipeline is closed, the tension spring pulls the wind shield assembly, and the air outlet is located below the windward plate. The wind shield assembly blocks the air outlet and the compressed air pipeline. When the compressed air pipeline is opened, the compressed air flow impacts the windward plate, pushing the windward plate to slide downward, thereby driving the wind shield plate to descend together. After the windward plate descends, the air outlet is located above the windward plate, and the air outlet is connected to the compressed air pipeline. Compressed air is blown out from the air outlet. At this time, the descending wind shield separates the air outlet and the detection camera located above the transparent detection platform, thereby preventing the air flow from entraining the lead paste powder to flow to the detection camera, thereby making it difficult for the lead paste powder to adhere to the lens of the detection camera.

DETAILED DESCRIPTION

[0030] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0031] like Figure 1 and Figure 2 As shown, this embodiment provides a battery plate detection device, including a transparent detection platform 1, a detection component 3, an assembly line 4 and a material discharge component 5.

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

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

[0034] The assembly line 4 includes a first section 401 and a second section 402 , wherein the first section 401 and the second section 402 are respectively located at two ends of the transparent detection platform 1 along the conveying direction.

[0035] The unloading assembly 5 is used for unloading unqualified plates 2; in a possible implementation, the unloading assembly 5 includes a cylinder 501 and a material frame 502 respectively arranged on both sides of the second section 402, and a push plate 503 for pushing the plate 2 is arranged on the telescopic rod of the cylinder 501, and the unqualified plate 2 is pushed to the material frame 502 by cooperating with the push plate 503.

[0036] The present invention sets the inspection platform as a transparent inspection platform 1, and sets inspection cameras 301 on both the upper and lower sides of the transparent inspection platform 1, so as to realize the appearance inspection of the front and back sides of the electrode plate 2, and the inspection is more comprehensive; the first section 401 of the set assembly line 4 is used to transport the electrode plate 2 to the transparent inspection platform 1. Because the length of the transparent inspection platform 1 is less than the length of the electrode plate 2, after the electrode plate 2 is separated from the contact with the first section 401, part of it has been transported to the second section 402, and the second section 402 drives the electrode plate 2 to continue to move, so as to 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 serving as each other's background and affecting the detection effect.

[0038] Furthermore, a bellows 6 is provided above the transparent detection platform 1, and the bellows 6 is located between the first detection camera and the second detection camera. An air outlet is provided at the bottom of the side wall of the bellows 6. Preferably, the air outlet is provided on the side of the bellows 6 away from the first detection camera; an air nozzle 7 corresponding to the air outlet is provided on the outer wall of the bellows 6, and the air nozzle 7 faces the detection area corresponding to the detection camera 301 located below the transparent detection platform 1, and away from the detection camera 301 located above the transparent detection platform 1, that is, the air nozzle 7 faces the detection area corresponding to the second detection camera and away from the first detection camera; a compressed air pipeline 8 is connected to the top of the bellows 6; some unqualified plates 2 will have lead paste powder falling onto the transparent detection platform 1, which will block the second detection camera and affect the detection effect of the bottom surface of the plate 2. By connecting the compressed air pipeline 8 to the bellows 6, the air outlet and the air nozzle 7 opened on the bellows 6 can blow away the lead paste powder on the detection area corresponding to the second detection camera on the transparent detection platform 1 to avoid blocking the detection camera 301 and affecting the detection.

[0039] Furthermore, a windshield assembly 9 is slidably connected inside the bellows 6, and the top of the bellows 6 is also connected to the windshield assembly 9 by a tension spring 10. The windshield assembly 9 includes a horizontally arranged windward plate 901 and a vertically arranged windshield plate 902, and the windward plate 901 is fixedly connected to the windshield plate 902. Optionally, the tension spring 10 can connect the windshield plate 902 to the top of the bellows 6. In addition, the tension spring 10 can also connect the windshield plate 901 to the top of the bellows 6; a through groove is provided on the bottom surface of the bellows 6 for the windshield plate 902 to extend out of the bellows 6; the first detection camera and the air outlet are respectively located on both sides of the windshield plate 902; when the bellows 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 is easy to stick to the detection camera 301 located above the transparent detection platform 1, that is, the lead paste powder is easy to stick to the first detection camera, affecting the detection effect; Figure 3 and Figure 4As shown, when the compressed air pipeline 8 is closed, the tension spring 10 pulls the windshield component 9, the air outlet is located below the windward plate 901, and the windshield component 9 blocks the air outlet and the compressed air pipeline 8; when the compressed air pipeline 8 is opened, the compressed air flow impacts the windward plate 901, pushing the windward plate 901 to slide downward, thereby driving the windshield plate 902 to descend together, and the windshield plate 902 abuts against the transparent detection platform 1. After the windward plate 901 descends, the air outlet is located above the windward plate 901, the air outlet is connected to the compressed air pipeline 8, and the compressed air is blown out from the air outlet. The lowered wind shield 902 separates the air outlet from the detection camera 301 located above the transparent detection platform 1, that is, the wind shield 902 separates the air outlet from the first detection camera, preventing the airflow from carrying the lead paste powder to the first detection camera, thereby making it difficult for the lead paste powder to stick to the lens of the first detection camera; because the wind shield 902 will abut against the transparent detection platform 1 when the compressed air pipeline 8 is opened, blocking the plate 2 from moving forward, the compressed air pipeline 8 should be opened intermittently, for example, in the gap between multiple plate 2 inspections, open it for a few seconds to blow away the lead paste powder, or, the compressed air pipeline 8 can be opened when the assembly line 4 stops.

[0040] Furthermore, a buffer strip 11 is provided at the bottom of the windshield 902 to provide a buffer when the windshield 902 contacts the transparent detection platform 1 , thereby protecting the transparent detection platform 1 and the windshield 902 .

[0042] Furthermore, a mounting plate 13 is provided between the detection camera 301 and its corresponding detection area, and an arched lampshade 14 is provided on the side of the mounting plate 13 close to the detection camera 301. The mounting plate 13 and the lampshade 14 are both provided with light-transmitting slits corresponding to the detection camera 301, and symmetrical strip light sources are provided along the light-transmitting slits on the mounting plate 13. By providing the strip light sources, the fill light at the detection camera 301 is uniform, which is beneficial to improving the detection effect.

[0043] Furthermore, it also includes a vacuum cleaner 15, the suction nozzle of the vacuum cleaner 15 is connected to an air collecting hood 16, and the air collecting hood 16 faces the air nozzle 7; the detection area corresponding to the second detection camera is located between the air collecting hood 16 and the air nozzle 7, and by arranging the vacuum cleaner 15 in conjunction with the bellows 6, the lead paste powder blown up by the air nozzle 7 on the bellows 6 can be sucked away to avoid the lead paste powder from polluting the environment. The setting of the air collecting hood 16 is beneficial to improving the effect of sucking the lead paste powder.
