Description

Technical Field

[0001] The present invention relates to the field of detection, and in particular to a device for detecting the adhesion of enameled copper paint films. Background Art

[0002] The main purpose of the enameled copper paint film adhesion test is to ensure that the enameled copper wire has reliable insulation performance and durability during use. By testing the paint film adhesion, the coating quality of the enameled copper wire can be evaluated, the production process can be optimized, the reliability of the product can be improved, and the excellent electrical insulation performance can be maintained under different environmental conditions.

[0003] During the current testing process, the depth of the grooves on the enameled copper body is difficult to accurately control, affecting the stability and repeatability of the test results. When conducting control experiments, the operator needs to repeatedly adjust the cutting depth, which not only increases the difficulty of operation, but also reduces the detection efficiency and may also cause deviations in the experimental data. When testing the same enameled copper body, if the scraping process is carried out in different time periods, the test conditions may not be completely consistent due to environmental factors or operational errors, affecting the accuracy of the experiment. If it is carried out simultaneously, the paint films are likely to interfere with each other, resulting in the stripping process being affected, destroying the independence of the paint film layer, affecting the reliability of the adhesion measurement, and thus reducing the credibility of the test data. Summary of the Invention

[0004] In order to overcome the shortcomings of the current testing process, the groove depth on the enameled copper body is difficult to accurately control, which affects the test stability and repeatability. The control experiment needs to repeatedly adjust the cutting amount, which increases the difficulty of operation and reduces the detection efficiency, and may also cause data deviation; time-sharing scraping is affected by environmental and operational errors, and the test conditions are difficult to be consistent. When scraping at the same time, the paint films are prone to interfere with each other, affecting the peeling effect and the reliability of adhesion measurement, and reducing the credibility of the test data. Therefore, it is necessary to provide a detection device for the adhesion of enameled copper paint film, which can accurately control the groove depth on the enameled copper body to ensure detection stability and repeatability; gradually adjust the cutting amount on one side to improve the efficiency of the control experiment and ensure data accuracy; synchronously scrape the paint films on both sides after notching to avoid interference, eliminate the influence of damage, ensure reliable adhesion measurement, and improve data credibility.

[0010] As a preferred technical solution of the present invention, the transmission assembly consists of two pulleys and a flat belt. The two pulleys are respectively connected to two rotating shafts, and a flat belt is wound between the two pulleys.

[0011] As a preferred technical solution of the present invention, the scraping mechanism includes a circular plate, a circular plate is installed on each of the two cylinders, a threaded rack is connected to each of the two circular plates through a threaded connection, an arc groove ring is installed on each of the two threaded racks, the two arc groove rings are respectively located in the two cylinders, and two arc groove rings are respectively provided with two arc grooves, each cylinder is slidably provided with two sliding blocks, and the ends of the two sliding blocks located on the same cylinder that are close to each other are rotatably provided with a roller, and the ends of the two sliding blocks located on the same cylinder that are away from each other are respectively installed with a scraper and a rubbing block, and each roller is respectively located in each arc groove.

[0012] As a preferred technical solution of the present invention, the detection mechanism includes an electronic tensile gauge, two electronic tensile gauges are embedded in one side of the shell, an annular guide rail is installed on both cylinders, and the tension arms on the two electronic tensile gauges are respectively slidably connected to the annular guide rails.

[0013] As a preferred technical solution of the present invention, it also includes a progressive mechanism, which includes a gear, a gear is installed on a threaded rack, a rack is slidably provided on one side of the shell, the gear is engaged with the rack, and a roller is rotatably provided on the other side of the rack, and an inclined groove rack is installed on the side of the frame close to the rack, and an inclined groove is opened on the inclined groove rack, and the roller is located in the inclined groove on the inclined groove rack.

[0014] As a preferred technical solution of the present invention, it also includes a carving mechanism, which includes a horizontal frame, two horizontal frames are slidably provided on the shell, a horizontal spring is respectively connected between the two horizontal frames and the two inner side surfaces of the shell, a carving knife is installed at the end of the two horizontal frames close to each other, and a guide wheel is rotatably provided at the end of the two horizontal frames away from each other, an inclined frame is installed on one side of the frame, and two inclined surfaces are provided on the inclined frame, and the two guide wheels are respectively in contact with the two inclined surfaces on the inclined frame.

[0015] The beneficial effects are: 1. The operator starts the output shaft of the servo motor and rotates it 180 degrees and then stops. The transmission assembly drives the two rotating shafts, two cylinders, two scrapers and two rubbing blocks to rotate synchronously 180 degrees and then stop. During the rotation, the two scrapers partially scrape off the paint film on the upper and lower sides of the enameled copper body respectively to form two grooves. The two rubbing blocks rotate 180 degrees and stop and then are precisely aligned and embedded in the two grooves formed on the enameled copper body to ensure the stability of the scraping position and improve the consistency and reliability of the detection; the operator controls the movement of the sliders of the two electric slides, and the sliders drive the movement of the shell, and the shell further drives the two scrapers and the two rubbing blocks to move. Since the two rubbing blocks are embedded in the grooves of the enameled copper body, the scrapers, rubbing blocks and annular guide rails remain stationary relative to the enameled copper body, while the electronic tension meter and the tension arm continue to move. In this process, the annular guide rail drives the tension The arm moves, so that the tension exerted on the tension arm is transmitted to the electronic tension meter in real time and the data is recorded, ensuring the accuracy and traceability of the measurement process. When the paint film on the enameled copper body reaches the limit of tension and is damaged, the tension value displayed on the electronic tension meter is the adhesion data of the paint film. This data can be used to judge whether the adhesion performance of the paint film meets the requirements and improve the scientific nature of quality inspection. The operator rotates the two threaded racks, and the threaded racks drive the arc groove ring to rotate. The two arc grooves on the arc groove ring act on the two sliding blocks and rollers on the same cylinder, causing them to move synchronously in the direction away from each other for a certain distance, and then drive the scraper and rubbing block on the same cylinder to move synchronously in the direction away from each other, so as to accurately adjust the cutting amount of the scraper, control the depth of the groove on the enameled copper body, improve the adaptability of the test to different paint film thicknesses, enhance the diversity and adjustability of the test, and achieve more refined adhesion testing.

[0016] 2. When the shell moves, it drives the gear, rack and roller to move synchronously for a certain distance and then stop. The roller slides along the inclined groove on the inclined groove frame for a certain distance and then stops. The guiding effect of the inclined groove ensures the stability and accuracy of the roller movement. During the movement, the roller drives the rack to intermittently move upward for a certain distance and then stop. The rack is gradually lifted and drives the gear to intermittently rotate for a certain angle and then stop. The rotation of the gear further drives the threaded frame and arc groove ring below to intermittently rotate for a certain angle and then stop. The two arc grooves on the arc groove ring provide precise guidance for the two sliding blocks and rollers on the same cylinder, making them intermittently and synchronously move toward each other. After moving a certain distance away from each other, they stop, thereby driving the scraper and rubbing block on the same cylinder to intermittently and synchronously move a certain distance away from each other and then stop, ensuring the controllability of the scraping process and the stability and uniformity of the stripping effect; the scraper and rubbing block on the upper cylinder remain fixed after the initial adjustment, so that the upper and lower paint films are compared under different working conditions, providing a stable reference benchmark for adhesion testing. Through comparative analysis, the adhesion performance of the paint film can be evaluated more accurately, the accuracy and reliability of the test results can be improved, and the flexibility and adaptability of the equipment under different testing requirements can be enhanced.

[0017] 3. When the shell moves, it drives the two cross frames, two cross springs, two carving knives and two guide wheels to move synchronously. When the two guide wheels are separated from the two inclined surfaces on the inclined plane frame, the two cross frames, two carving knives and two guide wheels move accurately towards each other under the elastic force of the two cross springs. The two carving knives fit tightly with the two sides of the enameled copper body to ensure the stability and consistency of the carving process. When the shell continues to move, it drives the two carving knives to slide along the two sides of the enameled copper body and form uniform and controllable scratches on the surface of the paint film, ensuring that the paint film is divided into two independent and non-interfering upper and lower parts. The film has a certain degree of ductility. When the scratch depth is the same, the upper and lower parts of the paint film will not interfere with each other when damaged. This can avoid the upper and lower paint films affecting each other when damaged, thereby ensuring the accuracy and reliability of the test results. If no scratching is performed and the paint film is allowed to separate naturally, the upper and lower paint films may interfere with each other when damaged, affecting the comparability and validity of the test data. By controlling the scratch depth and the accuracy of the scratch, the detection process can be ensured to be more stable and controllable, and the accuracy and repeatability of the paint film adhesion test can be improved, providing more reliable data support for the scientific evaluation of the paint film quality.

[0036] The clamping mechanism includes a support block 51. A support block 51 and a fixed block 52 are respectively installed on the two side surfaces of the frame 1 close to the opening 3. The fixed block 52 on the same side is located above the support block 51 on the same side. A fastening bolt 53 is threadedly connected to each of the two fixed blocks 52. An enameled copper body 54 is placed between the two support blocks 51, and the enameled copper body 54 passes through the two openings 3.

[0037] A rotating block 60 is rotatably provided on one side of the two fastening bolts 53 close to the supporting block 51 via a bearing. The rotating block 60 is used to press the enameled copper body 54 .

[0038] The driving mechanism includes a servo motor 61. A servo motor 61 is installed on the shell 4. The output shaft of the servo motor 61 rotates through one side of the shell 4. A vertical plate 62 is installed in the shell 4. Two rotating shafts 63 are rotatably provided on the vertical plate 62 through bearings. One end of one of the rotating shafts 63 is connected to the output shaft on the servo motor 61 through a coupling. A cylinder 64 is slidably provided on the two rotating shafts 63. The cylinder 64 will slide horizontally along the rotating shaft 63. A reset spring 65 is connected between the rotating shaft 63 and the cylinder 64. A transmission assembly 66 is provided between the two rotating shafts 63.

[0039] The transmission assembly 66 is composed of two pulleys and a flat belt. The two pulleys are respectively connected to the two rotating shafts 63, and a flat belt is wound between the two pulleys.

[0040] The scraping mechanism includes a circular plate 71, and a circular plate 71 is installed on each of the two cylinders 64. A threaded rack 72 is threadedly connected to each of the two circular plates 71, and an arc groove ring 73 is installed on each of the two threaded racks 72. The two arc groove rings 73 are respectively located in the two cylinders 64, and the two arc groove rings 73 are respectively provided with two arc grooves, a total of four arc grooves. Each cylinder 64 is slidably provided with two sliding blocks 74, which will slide along the cylinder 64. The two sliding blocks 74 located on the same cylinder 64 are each provided with a roller 75 rotatably provided at one end thereof which is close to each other through a bearing. A scraper 76 and a rubbing block 77 are respectively installed at the other end of the two sliding blocks 74 located on the same cylinder 64 which are away from each other. The scraper 76 is used to scrape the paint film on the enameled copper body 54 and form a groove. The rubbing block 77 is used to be stuck in the groove and press against one side of the groove. Each roller 75 is located in each arc groove.

[0041] The detection mechanism includes an electronic tension meter 41. Two electronic tension meters 41 are embedded in one side of the shell 4. An annular guide rail 43 is installed on each of the two cylinders 64. The tension arms 42 on the two electronic tension meters 41 are slidably connected to the annular guide rail 43 respectively.

[0042] The operator first passes the enameled copper body 54 through the two openings 3 and places it on the two supporting blocks 51. Then the operator rotates the two fastening bolts 53. Under the action of the fixed block 52, the two fastening bolts 53 and the two rotating blocks 60 rotate and move toward the supporting block 51. When the two rotating blocks 60 are against one side of the enameled copper body 54, the operator continues to rotate the two fastening bolts 53. The two rotating blocks 60 no longer rotate, and the enameled copper body 54 is clamped by the two rotating blocks 60 and the two supporting blocks 51; the operator rotates the two threaded racks 72 respectively, and the threaded rack 72 drives the arc groove ring 73 to rotate. Under the action of the two arc grooves on the arc groove ring 73, the two sliding blocks 74 and the roller 75 on the same cylinder 64 will synchronously move a certain distance away from each other, thereby driving the scraper 76 and the rubbing block 77 on the same cylinder 64 to synchronously move away from each other. The two scrapers 76 and the two rubbing blocks 77 are respectively scraped off a part of the paint film on the upper and lower sides of the enameled copper body 54 during the rotation process, thereby forming two grooves on the enameled copper body 54. After the two rubbing blocks 77 rotate 180 degrees and stop, they are located in the two grooves formed on the enameled copper body 54.Then the operator controls the sliders of the two electric slides 2 to move, and the sliders of the two electric slides 2 drive the shell 4 to move, and the shell 4 drives the servo motor 61, the vertical plate 62, the two rotating shafts 63, the two cylinders 64, the two return springs 65, the transmission assembly 66, the two circular plates 71, the two threaded racks 72, the two arc groove rings 73, the four sliding blocks 74, the four rollers 75, the two scrapers 76 and the two rubbing blocks 77 to move. Since the two rubbing blocks 77 are located in the two grooves formed on the enameled copper body 54, the cylinder 64, the circular plate 71, the threaded rack 72, the arc groove ring 73, the sliding blocks 74, the rollers 75, the scrapers 76, the rubbing blocks 77 and the annular guide rail 43 are in a stationary state relative to the enameled copper body 54, while the shell 4, the servo motor 61, the vertical plate 62, the rotating shaft 63, the transmission assembly 66, the electronic tension meter 4 1 and the tension arm 42 will continue to move, and the return spring 65 will be stretched accordingly. The cylinder 64, circular plate 71, threaded frame 72, arc groove ring 73, sliding block 74, roller 75, scraper 76, rubbing block 77 and annular guide rail 43 are moving relative to the housing 4, servo motor 61, vertical plate 62, rotating shaft 63, transmission assembly 66, electronic tension meter 41 and tension arm 42. During this process, the annular guide rail 43 drives the tension arm 42 to move, so that the tension exerted on the tension arm 42 is transmitted to the electronic tension meter 41 in real time and the data is recorded, ensuring the accuracy and traceability of the measurement process. When the paint film on the enameled copper body 54 withstands the tension to the limit and is damaged, the tension value displayed on the electronic tension meter 41 is the adhesion data of the paint film. This data can be used to determine whether the adhesion performance of the paint film meets the requirements, thereby improving the scientific nature of quality inspection;After the paint film attached to the enameled copper body 54 is damaged, the operator controls the sliders of the two electric slides 2 to stop moving, and then the operator starts the output shaft of the servo motor 61 to rotate 180 degrees and then stop, thereby driving the two cylinders 64, two return springs 65, two circular plates 71, two threaded racks 72, two arc groove rings 73, four sliding blocks 74, four rollers 75, two scrapers 76, and two rubbing blocks 77 to rotate 180 degrees and then stop, so that the two scrapers 76 and the two rubbing blocks 77 return to their initial states, and then control the sliders of the two electric slides 2 to continue moving, and the sliders of the two electric slides 2 drive the two scrapers 76 and the two rubbing blocks 77 to move The operator moves until there is no damage to the paint film on the enameled copper body 54, and then rotates the two threaded racks 72 again. The threaded rack 72 drives the arc groove ring 73 to rotate. Under the action of the two arc grooves on the arc groove ring 73, the two sliding blocks 74 and the roller 75 on the same cylinder 64 will synchronously move a certain distance away from each other, thereby driving the scraper 76 and the rubbing block 77 on the same cylinder 64 to move a certain distance away from each other again, and then adjust the cutting amount of the scraper 76, thereby controlling the depth of the groove on the enameled copper body 54 and improving the diversity of detection. Then, the two scrapers 76 and the two rubbing blocks 77 are controlled to rotate 180 degrees again. After rotating 180 degrees, the two scrapers 76 will respectively scrape off a part of the paint film on the upper and lower sides of the enameled copper body 54, thereby forming two grooves of different depths on the enameled copper body 54 again. The two rubbing blocks 77 will be located in the two grooves formed again on the enameled copper body 54 after rotating 180 degrees and stopping. In this way, the adhesion test of the paint film on the upper and lower sides of the enameled copper body 54 can be continuously performed repeatedly, thereby enhancing the diversity and adjustability of the test and achieving a more refined adhesion test. After the test is completed, the operator rotates the two fastening bolts 53 in the opposite direction. Under the action of the fixing block 52, the two fastening bolts 53 and the two rotating blocks 53 are tightened. Block 60 rotates while moving away from support block 51. When one side of the enameled copper body 54 of the two rotating blocks 60 separates, the operator removes the tested enameled copper body 54. The operator then controls the sliders of the two electric slides 2 to move in the opposite direction and reset. The sliders of the two electric slides 2 drive the housing 4 to move in the opposite direction and reset. The housing 4 then drives the servo motor 61, vertical plate 62, two rotating shafts 63, two cylinders 64, two reset springs 65, transmission assembly 66, two circular plates 71, two threaded racks 72, two arc groove rings 73, four sliding blocks 74, four rollers 75, two scrapers 76, and two rubbing blocks 77 to move in the opposite direction and reset.

[0043] Example 2: Based on Example 1, Figure 11-14As shown, it also includes a progressive mechanism arranged on the frame 1, the shell 4 and the threaded rack 72, the progressive mechanism is used to gradually advance the cutting amount of the scraper 76, the progressive mechanism includes a gear 81, a gear 81 is installed on one threaded rack 72, a rack 82 is slidably provided on one side of the shell 4, the gear 81 is engaged with the rack 82, and a roller 83 is rotatably provided on the other side of the rack 82 through a bearing, and a chute frame 84 is installed on the side of the frame 1 close to the rack 82, and the chute frame 84 has an chute, and the roller 83 is located in the chute on the chute frame 84.

[0044] When the shell 4 moves, it drives the gear 81, the rack 82 and the roller 83 to move a certain distance and then stop. As the roller 83 moves a certain distance on the inclined groove on the inclined groove frame 84 and then stops, the roller 83 drives the rack 82 to intermittently move upward for a certain distance and then stop. The rack 82 gradually moves and drives the gear 81 to intermittently rotate a certain angle and then stop. The gear 81 drives the threaded frame 72 and the arc groove ring 73 below to intermittently rotate a certain angle and then stop. Under the action of the two arc grooves on the arc groove ring 73, the two sliding blocks 74 and the roller 75 on the same cylinder 64 will intermittently rotate. The scraper 76 and the rubbing block 77 on the upper cylinder 64 are synchronously moved away from each other for a certain distance and then stopped, thereby driving the scraper 76 and the rubbing block 77 on the same cylinder 64 to intermittently move away from each other for a certain distance and then stop; the scraper 76 and the rubbing block 77 on the upper cylinder 64 remain fixed after the initial adjustment, so that the upper and lower paint films are compared under different working conditions, providing a stable reference benchmark for adhesion detection. Through comparative analysis, the adhesion performance of the paint film can be evaluated more accurately, the accuracy and reliability of the test results can be improved, and the flexibility and adaptability of the equipment under different detection requirements can be enhanced.

[0045] Example 3: Based on Example 2, Figure 11-14 As shown, it also includes a scoring mechanism arranged on the frame 1 and the shell 4, the scoring mechanism is used to divide the paint film on the enameled copper body 54 into two parts, the scoring mechanism includes a cross frame 91, two cross frames 91 are slidingly provided on the shell 4, and a cross spring 92 is respectively connected between the two cross frames 91 and the two inner side surfaces of the shell 4, and a scoring knife 93 for scoring the paint film on the enameled copper body 54 is installed at the end of the two cross frames 91 that are close to each other, and a guide wheel 94 is rotatably provided at the end of the two cross frames 91 that are away from each other, and a bevel frame 95 is installed on one side of the frame 1, and the bevel frame 95 is provided with two inclined surfaces, and the two guide wheels 94 are in contact with the two inclined surfaces on the bevel frame 95 respectively.

[0046] Initially, the two transverse springs 92 are in a compressed state. When the shell 4 moves, it drives the two transverse frames 91, the two transverse springs 92, the two carving knives 93 and the two guide wheels 94 to move. When the two guide wheels 94 are separated from the two inclined surfaces on the inclined frame 95, under the action of the two transverse springs 92, the two transverse frames 91, the two carving knives 93 and the two guide wheels 94 will move towards each other. The two carving knives 93 are tightly fitted with the two sides of the enameled copper body 54 respectively. When the shell 4 moves, it drives the two carving knives 93 to move on both sides of the enameled copper body 54, thereby scratching a scratch on the paint film on both sides of the enameled copper body 54 through the two carving knives 93, so that the paint film on the enameled copper body 54 is layered into two upper and lower parts that do not interfere with each other. Since the grooves on the upper and lower paint films are of different depths, the pulling force required to break the upper and lower paint films is also different. The two engraving knives 93 separate the paint film on the enameled copper body 54 into two non-interfering upper and lower parts, so that the upper and lower parts of the paint film will not interfere with each other when damaged. This can avoid the upper and lower paint films from affecting each other when damaged, thereby ensuring the accuracy and reliability of the test results, ensuring that the detection process is more stable and controllable, improving the accuracy and repeatability of paint film adhesion detection, and providing more reliable data support for the scientific evaluation of paint film quality; when the shell 4 moves in the opposite direction and resets, it drives the two cross frames 91, two cross springs 92, two engraving knives 93 and two guide wheels 94 to move in the opposite direction. When the two guide wheels 94 contact the two inclined surfaces on the inclined frame 95, the two cross frames 91, two engraving knives 93 and two guide wheels 94 will move away from each other, and the two engraving knives 93 are separated from the two sides of the enameled copper body 54, and the two cross springs 92 are compressed accordingly.
