[0001] The invention relates to the technical field of laser detection, and in particular to a laser detection device for surface defects of electrode foil produced for compressors. Background Art

[0002] Electrode foil is the key raw material for the manufacture of aluminum electrolytic capacitors. Due to the rapid development of the electronics industry, especially the rapid expansion of the market for complete machine products such as communications products, computers, and home appliances, electrode foil is basically used to produce aluminum electrolytic capacitors, so its development is highly dependent on the development of the aluminum electrolytic capacitor industry. Electrode foil includes corrosion foil and chemical foil. Without high-quality electrode foil, it is impossible to manufacture high-performance aluminum electrolytic capacitors. For electrode foil production, corrosion and chemical technology are the core technologies of electrode foil manufacturing. Therefore, there is an extremely important step in the production process of electrode foil, which is to perform laser detection on its surface to check whether there are defects, so as to ensure the integrity of the electrode foil.

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0038] like Figures 1 to 11 As shown, a laser detection device for surface defects of electrode foil for compressor production includes the following embodiments:

[0039] like Figures 1 to 5 As shown, embodiment 1 includes a detection frame 1, a first winding roller 101 with a wound electrode foil is installed at one end of the detection frame 1, and a second winding roller 102 is installed at the other end of the detection frame 1. The first winding roller 101 and the second winding roller 102 are both installed in a detachable manner, and a rotating motor is arranged on the outside of the detection frame 1. By fixing the output shaft of the rotating motor to one end of the second winding roller 102, the second winding roller 102 winds up the electrode foil on the first winding roller 101, and the outside of the electrode foil is detected during the winding process, and also includes:

[0040] A second support plate 3 is fixedly connected to the inner side of the detection frame 1, and two fixed disks 4 are arranged on one side of the second support plate 3. The two fixed disks 4 are symmetrically arranged up and down relative to the center line of the second support plate 3. One side of the two fixed disks 4 is rotatably connected to a rotating disk 5. A driving member for rotating the two rotating disks 5 is arranged inside the second support plate 3. Three mounting plates 501 are fixedly connected to one side of the rotating disk 5, and the three mounting plates 501 are arranged in a ring around the center of the rotating disk 5. Multiple laser detectors for detecting electrode foil defects are arranged on the outer sides of the three mounting plates 501;

[0041] In specific implementation, when the electrode foil is wound from the first winding roller 101 to the second winding roller 102 by the second winding roller 102, the outer side of the electrode foil is often inspected by a laser detector. The principle is that the laser is emitted by the laser. Within a certain wavelength range, the absorption and reflection of light by the material depends on its physical and chemical properties. By illuminating the surface of the electrode foil, the reflection and transmission of light by the surface defects can be observed. Specifically, the laser emitter emits laser pulses to irradiate the surface of the electrode foil. The presence of defects will affect the reflection and transmission characteristics of the laser, such as forming dark spots, changing the signals of the reflected wave and the transmitted wave, etc., so as to detect the defects of the electrode foil. However, the existing detection is often only for one side of the electrode foil, and the other side of the electrode foil needs to be re-detected later. Therefore, in this scheme, two rotating disks 5 are provided, and three mounting plates 501 are fixedly connected to the outer sides of the two rotating disks 5. The two sides of the electrode foil are inspected by multiple laser detectors on the mounting plates 501, thereby improving the overall detection efficiency.

[0042] like Figures 5 to 8 As shown, in the second embodiment, one side of the two fixed disks 4 is fixedly connected to a treatment cylinder 6, and a soot blowing assembly is arranged inside the treatment cylinder 6. When the mounting plate 501 rotates to the inside of the treatment cylinder 6, the soot blowing assembly blows and cleans the laser detector on the mounting plate 501, and a control plate 503 for inspection is fixedly connected to the outside of the fixed disk 4;

[0043] In specific implementation, during the actual detection process, when dust appears on the surface of the laser detector, it will inevitably lead to errors in the detection results. However, during the detection process, personnel cannot clean it. If the equipment is suspended, it will inevitably affect the detection efficiency, and it is impossible to know whether dust appears on the surface of the laser detector. Therefore, the fixed disk 4 is used to rotate to drive the three mounting plates 501 to rotate. After the detection of one group of mounting plates 501 is completed, the fixed disk 4 rotates the mounting plate 501 that has completed the detection to the inside of the processing tube 6, and the laser detector on the mounting plate 501 is blown clean by the soot blowing component inside the processing tube 6. The laser detector that has been cleaned before is moved to the position of the control plate 503 with the mounting plate 501, and the control plate 503 is detected by the cleaned laser detector to determine whether the laser detector is normal. After the test is completed, the laser detector is tested to ensure the accuracy of each test and avoid the problem of detection errors caused by dust or faults on the surface of the laser detector.

[0044] like Fig. 9 As shown, in this embodiment, the driving member includes two second sliders 301, and the two second sliders 301 are both slidably connected to the inside of the second support plate 3. Two second electric telescopic rods 302 are fixedly connected to the inside of the second support plate 3. The telescopic ends of the two second electric telescopic rods 302 are respectively fixedly connected to the two second sliders 301, and the two second sliders 301 are respectively fixedly connected to the two fixed plates 4.

[0045] The driving member also includes a second pulley 307 arranged on one side of the second slider 301. The rotating disk 5 sequentially passes through the fixed disk 4 and the second slider 301 and is fixedly connected to the fixed disk 4 and the second slider 301. The second pulley 307 is fixedly connected to the rotating disk 5. An L-shaped plate 303 is fixedly connected to the outer side of the second support plate 3. A connecting plate 304 is provided on one side of the L-shaped plate 303. The inner side of the connecting plate 304 is rotatably connected to the first pulley 306. The first pulley 306 and the two second pulleys 307 are connected by belt transmission. A first telescopic rod 305 and a second spring 308 are fixedly connected between the connecting plate 304 and the L-shaped plate 303, and the second spring 308 is sleeved on the outer side of the first telescopic rod 305. A first driving motor is fixedly connected to the outer side of one of the second sliders 301, and the output shaft of the first driving motor is fixedly connected to the second pulley 307.

[0046] In specific implementation, when the two rotating disks 5 need to rotate, by starting the first driving motor on a second slider 301, the first driving motor drives one of the second pulleys 307 to rotate, and at this time, the first pulley 306 and the other second pulley 307 are driven by the belt to transmit, so that the two fixed disks 4 rotate simultaneously. It is worth noting that in this scheme, the processing cylinder 6 and the control plate 503 on the upper fixed disk 4 are opposite to the processing cylinder 6 and the control plate 503 below, and then when the two fixed disks 4 rotate clockwise synchronously, the processing sequence of the laser detectors on the mounting plates 501 on the two fixed disks 4 is also consistent. When it is necessary to adjust the irradiation range of the laser detector according to electrode foils of different sizes, the second slider 301 can be driven to rise and fall by the second electric telescopic rod 302. At this time, the first telescopic rod 305 and the second spring 308 are fixedly connected between the connecting plate 304 outside the first pulley 306 and the L-shaped plate 303. The first telescopic rod 305 and the second spring 308 are adjusted to keep the two fixed disks 4 in a state of synchronous rotation.

[0047] like Figures 6 to 8 As shown, in this embodiment, the sootblowing assembly includes three partial gear rings 502, and the three partial gear rings 502 are respectively fixedly connected between three mounting plates 501, and an injection pipe 601 is arranged inside the processing tube 6, and a plurality of injection heads are arranged on the side of the injection pipe 601 relative to the partial gear ring 502, and the injection pipe 601 is fixedly connected to the rotating disk 5, and the rotating disk 5 is provided with an inflatable member, and a rotating rod 603 is rotatably connected to one side of the rotating disk 5, and a transmission gear 604 is fixedly connected to the outer side of the rotating rod 603, and the transmission gear 604 is meshed with the partial gear ring 502, and a traction member is arranged on the outer side of the rotating rod 603, when the transmission gear 604 is meshed with the partial gear ring 502, the inflatable member is pulled by the traction member for inflation, and when 604 is disengaged from the partial gear ring 502, the inflatable member supplies air to the injection pipe 601.

[0048] The inflatable part includes an air suction cylinder 602 fixedly connected to the fixed disk 4, a plurality of limit rods 6024 are fixedly connected inside the air suction cylinder 602, an adsorption disk 6022 is provided inside the air suction cylinder 602, the limit rods 6024 penetrate the adsorption disk 6022 and are slidably connected to the adsorption disk 6022, an air outlet pipe 6021 is fixedly connected between the air suction cylinder 602 and the injection pipe 601, a one-way air outlet valve is provided on the outside of the air outlet pipe 6021, a one-way air inlet valve is provided on the outside of the air suction cylinder 602, and a return spring 6025 is fixedly connected between the adsorption disk 6022 and one end inside the air suction cylinder 602.

[0049] The traction member includes a winding disk 605 fixedly connected to the outside of the rotating rod 603, a traction rope 6027 is wound and fixedly connected to the outside of the winding disk 605, one end of the traction rope 6027 passes through the suction cylinder 602 and is fixedly connected to the adsorption disk 6022, a plurality of guide wheels 6026 for guiding the traction rope 6027 are arranged on the outside of the suction cylinder 602, a fixed cylinder 606 is sleeved on the outside of the rotating rod 603, the fixed cylinder 606 is fixedly connected to the fixed disk 4, and a torsion spring 607 is fixedly connected between the fixed cylinder 606 and the rotating rod 603.

[0050] In a specific implementation, when the fixed disk 4 rotates, the partial gear rings 502 are fixedly connected between the three control plates 503, and one of the partial gear rings 502 is driven by the rotation of the fixed disk 4, and the partial gear ring 502 drives the meshing transmission gear 604 to rotate, and the transmission gear 604 drives the fixedly connected winding disk 605 to rotate. When the winding disk 605 rotates, it drives the traction rope 6027 wound on the outside. At this time, the traction rope 6027 contracts and pulls the adsorption disk 6022 fixedly connected at one end. At this time, the adsorption disk 6022 of the suction cylinder 602 moves, and the external gas is sucked into the interior of the suction cylinder 602 through the one-way air inlet valve. When the partial gear ring 50 2 is disengaged from the transmission gear 604, and when the mounting plate 501 is rotated to the inside of the processing cylinder 6, the rotating rod 603 is quickly reversed under the action of the torsion spring 607, and the adsorption plate 6022 is quickly pushed down by the return spring 6025, so that the gas inside the suction cylinder 602 is rushed into the inside of the injection pipe 601 through the outlet pipe 6021, and the laser detector on the mounting plate 501 is blown away by the injection head on the injection pipe 601, so as to ensure that the laser emitting device on the laser detector will not be dusty, and the detection accuracy of the laser detector is ensured. When the mounting plate 501 is switched for use, the laser detector on the mounting plate 501 is automatically cleaned.

[0051] like Figures 9 to 11 As shown, in the third embodiment, first support plates 2 are fixedly connected to both sides of the detection frame 1, and both ends of the two first support plates 2 are fixedly connected to supporting cross plates 201, and the two first support plates 2 are provided with two groups of cleaning components for cleaning the surface of the metal foil.

[0052] As a further solution of the present invention: the cleaning component includes a second belt roller 702, both ends of the second belt roller 702 are rotatably connected to the first slider 202, the two first sliders 202 are respectively slidably connected to the inside of the two first support plates 2, a first electric telescopic rod 203 is fixedly connected between the first slider 202 and the first support plate 2, a third belt roller 707 is rotatably connected between the two opposite supporting cross plates 201, a first belt roller 701 is provided between the two supporting cross plates 201, a cleaning belt 703 is sleeved between the first belt roller 701, the third belt roller 707 and the second belt roller 702, both ends of the first belt roller 701 are rotatably connected to the third slider 704, the third slider 704 is slidably connected to the inside of the supporting cross plate 201, a third telescopic rod 705 and a third spring 706 are fixedly connected between the third slider 704 and the supporting cross plate 201, and the third spring 706 is sleeved on the outside of the third telescopic rod 705.

[0053] A fixed frame 9 is provided between the two opposite supporting cross plates 201, and the cleaning belt 703 passes through the fixed frame 9. A scraper 901 is provided inside the fixed frame 9. The scraper 901 is fixedly connected to the inner wall of the fixed frame 9 with a plurality of fourth telescopic rods 902 and a plurality of fourth springs 903. The scraper 901 is in contact with the cleaning belt 703. An installation frame 904 is provided inside the fixed frame 9. A contact roller 905 is rotatably connected inside the installation frame 904, and the contact roller 905 is in contact with the other side of the cleaning belt 703. A fifth spring 907 and a plurality of fifth telescopic rods 906 are fixedly connected between the installation frame 904 and the fixed frame 9.

[0054] In specific implementation, before the electrode foil passes through the inspection, stains may appear on the surface of the electrode foil, thereby affecting the subsequent inspection. Therefore, in this solution, the electrode foil passes through two cleaning belts 703, and the cleaning belts 703 contact the two sides of the electrode foil, so as to clean the surface of the electrode foil. In order to ensure the cleaning effect of the cleaning belt 703 on the surface of the electrode foil, a second driving motor is installed on the two first sliders 202, and the second driving motor drives the second belt roller 702 to rotate. The second belt roller 702 passes through the first belt roller 701 and the third belt roller 707 to drive the cleaning belt 703, so that the cleaning belt 703 is constantly in contact with the surface of the electrode foil, and the first electric telescopic rod 203 can be started to push the first slider 202 to move, so that the two second belt rollers 702 adjust their positions according to the different thicknesses of the electrode foil, so that the cleaning belt 703 can fully contact the surface of the electrode foil, thereby cleaning the surface of the electrode foil, which is convenient for the subsequent detection of surface defects of the electrode foil;

[0055] In order to ensure that the stains on the surface of the cleaning belt 703 will not affect the contamination of the electrode foil, a fixed frame 9 is set up. When the cleaning belt 703 passes through the fixed frame 9, the scraper 901 and the contact roller 905 inside the fixed frame 9 form a right angle to scrape off the stains on the surface of the cleaning belt 703. The inside of the fixed frame 9 can be cleaned regularly.
