Description

Technical Field

[0001] This invention relates to the field of testing, and more particularly to a testing device for the adhesion of enameled copper coatings. Background Technology

[0002] The main purpose of testing the adhesion of enameled copper wire is to ensure that the enameled copper wire has reliable insulation performance and durability during use. By testing the adhesion of the enamel film, 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 ensured under different environmental conditions.

[0003] In the current testing process, the depth of the grooves on the enameled copper body is difficult to control precisely, affecting the stability and repeatability of the test results. When conducting control experiments, the operator needs to repeatedly adjust the depth of cut, which not only increases the difficulty of operation but also reduces the testing efficiency and may also lead to deviations in the experimental data. When testing the same enameled copper body, if the scraping process is carried out at different times, the testing 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 prone to interference with each other, which affects the peeling process, destroys the independence of the paint film layer, affects the reliability of the adhesion measurement, and thus reduces the credibility of the test data. Summary of the Invention

[0004] To overcome the current shortcomings of precise control over the groove depth on the enameled copper substrate during testing, which affects test stability and repeatability, and the need for repeated adjustments to the cutting depth in control experiments, increasing operational difficulty and reducing testing efficiency while potentially leading to data deviation; and the difficulty in maintaining consistent testing conditions due to environmental and operational errors in time-sharing scraping, which can cause interference between the coating films during simultaneous scraping, affecting the peeling effect and the reliability of adhesion measurement, thus reducing the credibility of test data, a testing device for the adhesion of enameled copper coating is needed. This device should be able to precisely control the groove depth on the enameled copper substrate, ensuring test stability and repeatability; gradually adjust the cutting depth on one side to improve the efficiency of control experiments and ensure data accuracy; and simultaneously scrape the coating films on both sides after scoring to avoid interference, eliminate the impact of damage, ensure reliable adhesion measurement, and improve data credibility.

[0005] The technical solution of the present invention is as follows: a testing device for the adhesion of enameled copper film, comprising a frame, an electric slide table installed on two sides of the frame, an opening on the other two sides of the frame, a housing between the two electric slide tables, a clamping mechanism installed on each of the two sides of the frame, a driving mechanism on the housing, a scraping mechanism on the driving mechanism, and a testing mechanism on the housing and the driving mechanism.

[0006] As a preferred embodiment of the present invention, the electric slide table consists of a drive motor, a lead screw, a nut, and a slider. The output shaft of the drive motor is connected to one end of the lead screw, the nut is connected to the lead screw by a thread, the slider is fixedly connected to the nut, and the upper and lower sides of the housing are respectively connected to two sliders.

[0007] As a preferred technical solution of the present invention, the clamping mechanism includes a support block. A support block and a fixing block are respectively installed on two sides of the frame near the opening. The fixing block on the same side is located above the support block on the same side. A fastening bolt is threadedly connected to each of the two fixing blocks. An enameled copper body is placed between the two support blocks and passes through the two openings.

[0008] As a preferred embodiment of the present invention, each of the two fastening bolts is provided with a rotating block on the side near the support block.

[0009] As a preferred embodiment of the present invention, the driving mechanism includes a servo motor. A servo motor is mounted on a housing. The output shaft of the servo motor passes through one side of the housing. A vertical plate is installed inside the housing. Two rotating shafts are rotatably mounted on the vertical plate. One end of one of the rotating shafts is connected to the output shaft of the servo motor. A cylinder is slidably mounted on each of the two rotating shafts. A return spring is connected between the rotating shaft and the cylinder. A transmission component is provided between the two rotating shafts.

[0010] As a preferred embodiment 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 embodiment of the present invention, the scraping mechanism includes a circular plate. A circular plate is installed on each of the two cylinders. A threaded bracket is threadedly connected to each of the two circular plates. An arc groove ring is installed on each of the two threaded brackets. The two arc groove rings are located in the two cylinders respectively. Two arc grooves are opened on each of the two arc groove rings. Two sliding blocks are slidably provided on each cylinder. A roller is rotatably provided at the end of the two sliding blocks located on the same cylinder that are close to each other. A scraper and a scraping block are respectively installed at the end of the two sliding blocks located on the same cylinder that are far from each other. Each roller is located in each arc groove.

[0012] As a preferred embodiment of the present invention, the testing mechanism includes an electronic tension gauge. Two electronic tension gauges are embedded in one side of the housing. An annular guide rail is installed on each of the two cylinders. The tension arms on the two electronic tension gauges are slidably connected to the annular guide rails respectively.

[0013] As a preferred technical solution of the present invention, it also includes a progressive mechanism, which includes a gear, a gear is mounted on a threaded frame, a rack is slidably provided on one side of the housing, the gear meshes with the rack, a roller is rotatably provided on the other side of the rack, and a slant frame is installed on the side of the frame near the rack, with a slant groove on the slant frame, and the roller is located in the slant groove on the slant frame.

[0014] As a preferred technical solution of the present invention, it also includes a scribing mechanism, which includes a crossbeam. Two crossbeams are slidably provided on the housing. A horizontal spring is connected between the two crossbeams and the two inner sides of the housing. A scribing knife is installed at the end of the two crossbeams that are close to each other. A guide wheel is rotatably provided at the end of the two crossbeams that are far from each other. A sloping frame is installed on one side of the frame. Two inclined surfaces are provided on the sloping frame. The two guide wheels are in contact with the two inclined surfaces on the sloping frame respectively.

[0015] The beneficial effects are as follows: 1. After the operator starts the servo motor, the output shaft rotates 180 degrees and then stops. The transmission assembly drives two rotating shafts, two cylinders, two scrapers, and two scraping blocks to rotate 180 degrees synchronously and then stop. During rotation, the two scrapers partially scrape away the enamel film on the upper and lower sides of the enameled copper body, forming two grooves. After rotating 180 degrees and stopping, the two scraping blocks are precisely aligned and embedded in the two grooves formed on the enameled copper body, ensuring stable scraping position and improving the consistency and reliability of the inspection. 2. The operator controls the movement of the sliders of the two electric slides, which in turn move the housing. The housing further drives the two scrapers and two scraping blocks to move. Because the two scraping blocks are embedded in the grooves of the enameled copper body, the scrapers, scraping blocks, and annular guide rail remain stationary relative to the enameled copper body, while the electronic force gauge and tension arm continue to move. During this process, the annular guide rail drives the tension... The arm moves, transmitting the tensile force on the arm to the electronic tensile gauge in real time and recording the data, ensuring the accuracy and traceability of the measurement process. When the paint film on the enameled copper body reaches its limit and breaks, the tensile force value displayed on the electronic tensile gauge 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, improving the scientific nature of quality inspection. The operator rotates two threaded brackets, which drive the arc groove ring to rotate. The two arc grooves on the arc groove ring act on two sliding blocks and rollers on the same cylinder, causing them to move synchronously a certain distance away from each other. This, in turn, drives the scraper and rubbing block on the same cylinder to move synchronously away from each other, thereby precisely adjusting the cutting depth of the scraper, controlling the depth of the groove on the enameled copper body, improving the adaptability of the test to different paint film thicknesses, enhancing the diversity and adjustability of the test, and achieving more refined adhesion testing.

[0016] 2. When the shell moves, it drives the gear, rack, and roller to move synchronously a certain distance and then stops. The roller slides along the inclined groove on the inclined groove frame a certain distance and then stops. The guiding effect of the inclined groove ensures the smoothness and accuracy of the roller's movement. During the movement, the roller drives the rack to move intermittently upward a certain distance and then stops. The rack gradually rises and drives the gear to rotate intermittently a certain angle and then stops. The rotation of the gear further drives the threaded frame and the arc groove ring below to rotate intermittently a certain angle and then stops. The two arc grooves on the arc groove ring provide precise guidance to the two sliding blocks and rollers on the same cylinder, causing them to move intermittently and synchronously towards each other. After moving a certain distance away from each other, the scraper and rubbing block on the same cylinder intermittently and synchronously move a certain distance away from each other before stopping, ensuring the controllability of the scraping process and guaranteeing the stability and uniformity of the peeling effect. The scraper and rubbing block on the upper cylinder remain fixed after the initial adjustment, allowing the upper and lower paint films to form a comparison 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, improving the accuracy and reliability of the test results, while enhancing the flexibility and adaptability of the equipment under different testing requirements.

[0017] 3. When the shell moves, it drives two crossbeams, two horizontal springs, two engraving blades, and two guide wheels to move synchronously. After the two guide wheels disengage from the two inclined surfaces on the inclined frame, under the elastic force of the two horizontal springs, the two crossbeams, two engraving blades, and two guide wheels move precisely towards each other. The two engraving blades fit tightly against both sides of the enameled copper body, ensuring the stability and consistency of the engraving process. As the shell continues to move, it drives the two engraving blades to slide along both sides of the enameled copper body, forming uniform and controllable scratches on the enamel film surface. This ensures that the enamel film is divided into two independent and non-interfering upper and lower parts. The film has a certain degree of extensibility. 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 from affecting each other when damaged, thus ensuring the accuracy and reliability of the test results. If the paint film is not scratched and 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 testing process can be made more stable and controllable, improving the accuracy and repeatability of paint film adhesion testing, and providing more reliable data support for the scientific evaluation of paint film quality.

Detailed Implementation

[0033] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments, but this is not intended to limit the present invention.

[0034] Example 1: A device for detecting the adhesion of enameled copper coating, such as... Figures 1-10 As shown, the device includes a frame 1, with an electric slide 2 mounted on two opposite sides of the frame 1. An opening 3 is opened on the other two opposite sides of the frame 1. A housing 4 is provided between the two electric slides 2. A clamping mechanism is installed on the two sides of the frame 1 near the opening 3. The clamping mechanism is used to clamp the enameled copper body 54. A drive mechanism is provided on the housing 4. A scraping mechanism is provided on the drive mechanism. The scraping mechanism is used to scrape off the paint film on the enameled copper body 54. A detection mechanism is provided on the housing 4 and the drive mechanism. The detection mechanism is used to detect and record the tensile force value required for the paint film on the enameled copper body 54 to fall off.

[0035] The electric slide table 2 consists of a drive motor, a lead screw, a nut, and a slider. The output shaft of the drive motor is connected to one end of the lead screw, the nut is connected to the lead screw by a thread, the slider is fixedly connected to the nut, and the upper and lower sides of the housing 4 are respectively connected to two sliders.

[0036] The clamping mechanism includes a support block 51. A support block 51 and a fixing block 52 are respectively installed on the two sides of the frame 1 near the opening 3. The fixing 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 fixing blocks 52. A copper enameled body 54 is placed between the two support blocks 51 and passes through the two openings 3.

[0037] Two fastening bolts 53 are each provided with a rotating block 60 on the side near the support block 51 via a bearing. The rotating block 60 is used to press the enameled copper body 54.

[0038] The drive mechanism includes a servo motor 61. A servo motor 61 is mounted on the housing 4. The output shaft of the servo motor 61 rotatably passes through one side of the housing 4. A vertical plate 62 is installed inside the housing 4. Two rotating shafts 63 are rotatably mounted on the vertical plate 62 via bearings. One end of one of the rotating shafts 63 is connected to the output shaft of the servo motor 61 via a coupling. A cylindrical body 64 is slidably mounted on each of the two rotating shafts 63. The cylindrical body 64 slides horizontally along the rotating shaft 63. A return spring 65 is connected between the rotating shaft 63 and the cylindrical body 64. A transmission component 66 is provided between the two rotating shafts 63.

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

[0040] The scraping mechanism includes a circular plate 71. A circular plate 71 is installed on each of the two cylinders 64. A threaded bracket 72 is threadedly connected to each of the two circular plates 71. An arc groove ring 73 is installed on each of the two threaded brackets 72. The two arc groove rings 73 are located inside the two cylinders 64 respectively. Each arc groove ring 73 has two arc grooves, for a total of four arc grooves. Two sliding blocks 74 are slidably provided on each cylinder 64. The sliding blocks 74 slide along the cylinder 64. At the ends of the two sliding blocks 74 located on the same cylinder 64, which are close to each other, a roller 75 is rotatably provided through a bearing. At the ends of the two sliding blocks 74 located on the same cylinder 64, which are far apart from each other, a scraper 76 and a scraper block 77 are respectively installed. The scraper 76 is used to scrape off the paint film on the enameled copper body 54 and form a groove. The scraper block 77 is used to fit into the groove and abut against one side of the groove. Each roller 75 is located in each arc groove.

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

[0042] The operator first places the enameled copper body 54 through the two openings 3 onto the two support blocks 51. Then, the operator rotates the two fastening bolts 53. Under the action of the fixing block 52, the two fastening bolts 53 and the two rotating blocks 60 rotate and move closer to the support blocks 51. When the two rotating blocks 60 abut against one side of the enameled copper body 54, the operator continues to rotate the two fastening bolts 53, and the two rotating blocks 60 stop rotating. The enameled copper body 54 is clamped by the two rotating blocks 60 and the two support blocks 51. The operator then rotates the two threaded brackets 72, which drive 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 move a certain distance away from each other in sync, thereby driving the scraper 76 and the scraping block 77 on the same cylinder 64 to move away from each other in sync. Move a certain distance; then the operator starts the output shaft of the servo motor 61 to rotate 180 degrees and stop. The output shaft of the servo motor 61 drives one of the rotating shafts 63 to rotate 180 degrees and stop. One of the rotating shafts 63 drives another rotating shaft 63 to rotate 180 degrees and stop through the transmission component 66. The two rotating shafts 63 drive the two cylinders 64, two return springs 65, two round plates 71, two threaded brackets 72, two arc groove rings 73, four sliding blocks 74, four rollers 75, two scrapers 76, two rubbing blocks 77 and two annular guide rails 43 to rotate 180 degrees and stop. During the rotation of the two scrapers 76, a portion of the paint film on the upper and lower sides of the enameled copper body 54 will be scraped off, thereby forming two grooves on the enameled copper body 54. After the two rubbing blocks 77 rotate 180 degrees and stop, they are exactly located in the two grooves formed on the enameled copper body 54.Next, the operator controls the sliders of the two electric slide tables 2 to move. The sliders of the two electric slide tables 2 drive the housing 4 to move. The housing 4 drives the servo motor 61, vertical plate 62, two rotating shafts 63, two cylinders 64, two return springs 65, transmission assembly 66, two circular plates 71, two threaded brackets 72, two arc groove rings 73, four sliding blocks 74, four rollers 75, two scrapers 76, and two friction blocks 77 to move. Since the two friction blocks 77 are located in the two grooves formed on the enameled copper body 54, the cylinders 64, circular plates 71, threaded brackets 72, arc groove rings 73, sliding blocks 74, rollers 75, scrapers 76, friction blocks 77, and annular guide rail 43 are stationary relative to the enameled copper body 54. Meanwhile, the housing 4, servo motor 61, vertical plate 62, rotating shafts 63, transmission assembly 66, and electronic tension gauge 4 are all stationary. 1 and the tension arm 42 will continue to move, and the return spring 65 will stretch 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 component 66, electronic tension gauge 41 and tension arm 42. During this process, the annular guide rail 43 drives the tension arm 42 to move, so that the tension force on the tension arm 42 is transmitted to the electronic tension gauge 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 reaches the limit of the tension and breaks, the tension value displayed on the electronic tension gauge 41 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.After the enamel film adhering to the copper body 54 is damaged, the operator controls the sliders of the two electric slides 2 to stop moving. Then, the operator starts the output shaft of the servo motor 61 to rotate 180 degrees and stop, thereby driving the two cylinders 64, two return springs 65, two circular plates 71, two threaded brackets 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 stop, so that the two scrapers 76 and two rubbing blocks 77 return to their initial state. Then, the operator controls 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 two rubbing blocks 77 to move. Once the enameled copper body 54 is free of any damage to the enamel film, the operator rotates the two threaded brackets 72 again. The threaded brackets 72 drive 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 rollers 75 on the same cylinder 64 will move synchronously a certain distance away from each other. This causes the scraper 76 and the rubbing block 77 on the same cylinder 64 to move synchronously a certain distance away from each other again, thereby adjusting the cutting depth of the scraper 76 and controlling the depth of the grooves on the enameled copper body 54, improving the diversity of inspection. Then, the two scrapers 76 and the two rubbing blocks 77 are rotated 180 degrees again. After a 10-degree rotation, the two scrapers 76 will scrape away a portion of the paint film on the upper and lower sides of the enameled copper body 54, thus creating two new grooves of varying depths on the enameled copper body 54. The two scraping blocks 77, after rotating 180 degrees and stopping, will be positioned precisely within these two newly formed grooves on the enameled copper body 54. This process can be repeated to continuously test the adhesion of the paint film on the upper and lower sides of the enameled copper body 54, enhancing the diversity and adjustability of the testing and achieving more refined adhesion testing. After the test, 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... While rotating, block 60 moves away from support block 51. After the two rotating blocks 60 separate on one side of the enameled copper body 54, the operator removes the tested enameled copper body 54. Then, the operator controls the sliders of the two electric slide tables 2 to move in the opposite direction to reset. The sliders of the two electric slide tables 2 drive the housing 4 to move in the opposite direction to 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 brackets 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 to reset.

[0043] Example 2: Based on Example 1, such as Figures 11-14As shown, it also includes a progressive mechanism disposed on the frame 1, housing 4 and threaded bracket 72. The progressive mechanism is used to progressively increase the cutting depth of the scraper 76. The progressive mechanism includes a gear 81, one of which is mounted on the threaded bracket 72. A rack 82 is slidably disposed on one side of the housing 4. The gear 81 meshes with the rack 82. A roller 83 is rotatably disposed on the other side of the rack 82 via a bearing. A slant bracket 84 is mounted on the side of the frame 1 near the rack 82. A slant bracket 84 is opened on the slant bracket 84. The roller 83 is located in the slant bracket 84.

[0044] When the housing 4 moves, it drives the gear 81, rack 82, and roller 83 to move a certain distance and then stop. As the roller 83 moves a certain distance on the inclined groove of the inclined groove frame 84 and then stops, the roller 83 drives the rack 82 to move upward intermittently a certain distance and then stop. The rack 82 gradually moves, driving the gear 81 to rotate intermittently a certain angle and then stop. The gear 81 drives the threaded frame 72 and the arc groove ring 73 below to rotate intermittently 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... The two paint films move synchronously and intermittently in opposite directions for a certain distance before stopping, thereby causing the scraper 76 and the rubbing block 77 on the same cylinder 64 to move synchronously and intermittently in opposite directions for a certain distance before stopping. 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 can be 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, improving the accuracy and reliability of the test results, while enhancing the flexibility and adaptability of the equipment under different testing requirements.

[0045] Example 3: Based on Example 2, such as Figures 11-14 As shown, it also includes a scribing mechanism set on the frame 1 and the housing 4. The scribing mechanism is used to divide the paint film on the enameled copper body 54 into two parts. The scribing mechanism includes a crossbeam 91. Two crossbeams 91 are slidably provided on the housing 4. A horizontal spring 92 is connected between the two crossbeams 91 and the two inner sides of the housing 4. A scribing knife 93 for scribing on the paint film on the enameled copper body 54 is installed at the end of the two crossbeams 91 that are close to each other. A guide wheel 94 is rotatably provided at the end of the two crossbeams 91 that are far from each other. A slant frame 95 is installed on one side of the frame 1. The slant frame 95 is provided with two inclined surfaces. The two guide wheels 94 are in contact with the two inclined surfaces on the slant frame 95 respectively.

[0046] Initially, the two transverse springs 92 are compressed. When the housing 4 moves, it drives the two crossbeams 91, the two transverse springs 92, the two engraving knives 93, and the two guide wheels 94 to move. After the two guide wheels 94 separate from the two inclined surfaces on the inclined frame 95, under the action of the two transverse springs 92, the two crossbeams 91, the two engraving knives 93, and the two guide wheels 94 will move towards each other. The two engraving knives 93 are tightly attached to both sides of the enameled copper body 54. When the housing 4 moves, it drives the two engraving knives 93 to move on both sides of the enameled copper body 54, thereby scratching a line on the enameled copper body 54 on both sides of the enameled copper body 54. This creates two independent upper and lower parts of the enameled copper body 54. Because the grooves on the upper and lower enameled copper bodies are of different depths, the tensile force required to break the upper and lower enameled copper bodies is also different. Two engraving knives 93 separate the paint film on the enameled copper body 54 into two independent upper and lower parts, preventing interference between the two parts when damaged. This avoids mutual influence between the upper and lower paint films when damaged, ensuring the accuracy and reliability of the test results. It also ensures a more stable and controllable testing process, improves the accuracy and repeatability of paint film adhesion testing, and provides more reliable data support for the scientific evaluation of paint film quality. When the housing 4 moves in the reverse direction to reset, it drives the two crossbeams 91, two horizontal 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 crossbeams 91, two engraving knives 93, and two guide wheels 94 will move in a direction away from each other. The two engraving knives 93 separate from the two sides of the enameled copper body 54, and the two horizontal springs 92 are compressed accordingly.
