Description

Technical Field

[0001] This utility model belongs to the field of enameled wire tape adhesion testing technology, specifically relating to a device for testing the adhesion of enameled wire surface tape. Background Technology

[0002] Enameled wire is a major type of winding wire, consisting of a conductor and an insulation layer. The bare wire is annealed and softened, then coated with enamel multiple times and baked. However, producing products that meet both standard requirements and customer needs is not easy, as it is affected by factors such as raw material quality, process parameters, production equipment, and environment. To ensure the performance stability and reliability of enameled wire, especially in applications where tape needs to be wrapped around it, such as during magnetic ring winding, the adhesive strength of the tape directly affects the product's quality and lifespan. Therefore, it is usually necessary to test the surface adhesive strength of the enameled wire. Currently, the testing of the adhesive strength of the tape on the enameled wire surface mainly relies on manual operation, where workers manually apply and remove the tape to assess the adhesive strength. This method is not only time-consuming and labor-intensive with a single testing method, but also highly subjective, making it difficult to form standardized data records, and exhibiting significant deficiencies in accuracy and stability.

[0015] This specific embodiment is a device for detecting the adhesion force of adhesive tape on the surface of enameled wire, and its structural schematic diagram is shown below. Figures 1-7 As shown, it includes: a base 1, with a constant temperature heating platform 6 and a constant temperature cooling platform 12 installed at both ends of the base 1 respectively, an enameled wire harness 7 installed above the constant temperature heating platform 6 and the constant temperature cooling platform 12, and a fixing mechanism installed on the outer surface of the constant temperature heating platform 6 and the constant temperature cooling platform 12, and an adhesive detection mechanism installed inside the base 1 through a bracket 5.

[0016] Specifically, the fixing mechanism can fix both ends of the enameled wire harness 7 to the constant temperature heating platform 6 and the constant temperature cooling platform 12. Then, the adhesive testing mechanism is used to stick tape onto the enameled wire harness 7. By setting the constant temperature heating platform 6 and the constant temperature cooling platform 12, the enameled wire harness 7 can be heated or cooled to test the adhesive strength of the tape on the surface of the enameled wire harness 7 at different temperatures, ensuring the accuracy of the test. Under the action of the adhesive testing mechanism, the tape is torn off the enameled wire harness 7 and the adhesive strength is tested. The adhesive testing mechanism simulates the production line of the enameled wire harness 7 winding tape, preventing errors caused by excessive manual intervention and mechanical installation of tape and enameled wire harness 7 during the test, further ensuring the accuracy of the test.

[0017] Furthermore, the fixing mechanism includes an n-shaped frame 19, and the n-shaped frame 19 is slidably mounted on the outer surfaces of the constant temperature heating platform 6 and the constant temperature cooling platform 12. The outer surfaces of the constant temperature heating platform 6 and the constant temperature cooling platform 12 are both mounted on a base 22. The n-shaped frame 19 is internally threaded with a lead screw 21, and the bottom end of the lead screw 21 is rotatably connected to the base 22.

[0018] Specifically, by placing both ends of the enameled wire harness 7 onto the constant temperature heating platform 6 and the constant temperature cooling platform 12 respectively and tightening them, and then rotating the lead screw 21 to drive the n-shaped frame 19 to descend and press down on the enameled wire harness 7, the enameled wire harness 7 is tightened and fixed.

[0019] Furthermore, a clamping plate 17 is installed on the outer surface of the n-type frame 19.

[0020] Specifically, the clamp 17 can press the excess parts at both ends of the enameled wire harness 7 tightly against the constant temperature heating platform 6 and the constant temperature cooling platform 12, thereby increasing the heating or cooling effect of the constant temperature heating platform 6 and the constant temperature cooling platform 12 on the enameled wire harness 7.

[0021] Furthermore, anti-slip pads 18 are installed on the bottom surfaces of both the n-shaped frame 19 and the clamping plate 17.

[0022] Specifically, the anti-slip pad 18 increases the friction between the n-shaped frame 19 and the clamp 17 and the enameled wire harness 7, preventing the enameled wire harness 7 from sliding when fixed.

[0023] Furthermore, a handle 20 is installed at the top of the lead screw 21, and the outer surface of the handle 20 is provided with anti-slip texture.

[0024] Specifically, the handle 20 is designed to facilitate the user's rotation of the lead screw 21 and prevent the user from slipping when rotating the lead screw 21.

[0025] Furthermore, positioning rings 23 are installed on the outer surfaces of both the constant temperature heating stage 6 and the constant temperature cooling stage 12. The end of the positioning ring 23 away from the lead screw 21 is slidably installed inside the n-shaped frame 19.

[0026] Specifically, the positioning ring 23 limits the n-shaped frame 19 to prevent it from shaking when sliding and increases the stability of the n-shaped frame 19.

[0027] Furthermore, the adhesive detection mechanism includes a bracket 5 and a slip ring 3 mounted at the top. A rotating ring 4 is slidably mounted inside the slip ring 3, and a housing 8 is installed through the outer surface of the slip ring 3. The outer surface of the rotating ring 4 is provided with a toothed groove 25. A motor 9 is mounted on the outer surface of the housing 8, and the output end of the motor 9 is rotatably mounted inside the housing 8. A gear 24 is mounted on the output end of the motor 9, and the gear 24 is driven by the toothed groove 25. A rotating seat 11 is mounted on the outer surface of the rotating ring 4, and an electric push rod 10 and a battery 2 are mounted on the outer surface of the rotating seat 11. A force sensor 13 is mounted on the telescopic end of the electric push rod 10, and the battery 2 is electrically connected to the electric push rod 10 and the force sensor 13. An L-plate 14 is mounted on the outer surface of the force sensor 13, and a one-way damping rotating shaft 26 is mounted on the outer surface of the L-plate 14. A rubber roller 16 is mounted inside the one-way damping rotating shaft 26, and a tape roll 15 is mounted on the outside of the rubber roller 16.

[0028] Specifically, by installing the tape roll 15 onto the tape roller 16, the tape roll 15 is pulled and pasted onto the surface of the enameled wire harness 7. Then, the motor 9 starts and drives the gear 24 to rotate in the forward direction. Under the action of the tooth groove 25, the drive ring 4 rotates. The rotation of the ring 4 drives the rotating seat 11 and the electric push rod 10 to rotate, which in turn drives the force sensor 13, the L plate 14 and the tape roll 15 installed on the tape roller 16 in the one-way damping shaft 26 to rotate. This pulls the fixed end of the tape roll 15, causing the tape roller 16 installed in the one-way damping shaft 26 to rotate. The rotation of the tape roller 16 causes the fixed end of the tape roll 15 to rotate and loosen, and the tape roll 15 rotates around the enameled wire harness 7 and is pasted. After the tape roll 15 is attached to the enameled wire harness 7, the motor 9 is started to control the gear 24 to rotate in the reverse direction. Under the action of the tooth groove 25, the drive belt rotates the rotating ring 4 in the reverse direction. The reverse rotation of the rotating ring 4 causes the rotating seat 11 and the electric push rod 10 to rotate in the reverse direction, thereby causing the force sensor 13 and the L plate 14 to flip. The one-way damping shaft 26 will not rotate during the flipping, thus fixing the rubber roller 16 and the tape roll 15. When the electric push rod 10 rotates in the reverse direction, it starts to pull the force sensor 13, the L plate 14, the rubber roller 16, and the tape roll 15 away from the enameled wire harness 7. The tape roll 15, which is attached to the surface of the enameled wire harness 7, is pulled off. When the tape roll 15 is torn off the surface of the enameled wire harness 7, it is subjected to a tensile force. The tensile force is transmitted to the force sensor 13 through the adhesive roller 16, the one-way damping shaft 26, and the L plate 14. The pressure index displayed by the force sensor 13 is transmitted to the display screen via radio, thereby obtaining the adhesive force between the tape and the enameled wire. The mechanical tape application is consistent with the tape application process of the enameled wire harness 7, which prevents the errors caused by traditional manual tape application and mechanical tape application, and ensures the accuracy and stability of the measurement.

[0029] This utility model discloses a device for testing the adhesive force of tape on the surface of enameled wire. The device works by placing both ends of the enameled wire bundle 7 onto a constant-temperature heating platform 6 and a constant-temperature cooling platform 12, respectively, and tightening them. Then, rotating the lead screw 21 causes the n-shaped frame 19 to descend and press down on the enameled wire bundle 7, thus achieving tension and fixation of the enameled wire bundle 7. Next, the enameled wire harness 7 is heated or cooled sequentially using the constant temperature heating stage 6 and the constant temperature cooling stage 12 to test the adhesion of the adhesive tape on the surface of the enameled wire harness 7 at different temperatures, ensuring the accuracy of the test. Then, by installing the tape roll 15 onto the tape roller 16, the tape roll 15 is pulled and pasted onto the surface of the enameled wire harness 7. Then, the motor 9 starts and drives the gear 24 to rotate in the forward direction. Under the action of the tooth groove 25, the drive ring 4 rotates. The rotation of the ring 4 drives the rotating seat 11 and the electric push rod 10 to rotate, which in turn drives the force sensor 13, the L plate 14 and the tape roll 15 installed on the tape roller 16 in the one-way damping shaft 26 to rotate. This pulls the fixed end of the tape roll 15 to make the tape roller 16 installed in the one-way damping shaft 26 rotate. The rotation of the tape roller 16 drives the fixed end of the tape roll 15 to rotate and loosen, and makes the tape roll 15 rotate around the enameled wire harness 7 and paste. Finally, after the tape roll 15 is attached to the enameled wire harness 7, the motor 9 is started to control the gear 24 to rotate in the reverse direction. Under the action of the tooth groove 25, the drive belt rotates the rotating ring 4 in the reverse direction. The reverse rotation of the rotating ring 4 causes the rotating seat 11 and the electric push rod 10 to rotate in the reverse direction, which in turn drives the force sensor 13 and the L plate 14 to flip. The one-way damping shaft 26 does not rotate when flipping, thus fixing the rubber roller 16 and the tape roll 15. When the electric push rod 10 rotates in the reverse direction, it pulls the force sensor 13, the L plate 14, the rubber roller 16, and the tape roll 15 away from the enameled wire harness 7. The tape roll 15, which is attached to the surface of the enameled wire harness 7, is pulled off. When the tape roll 15 is torn off the surface of the enameled wire harness 7, it is subjected to a tensile force. The tensile force is transmitted to the force sensor 13 through the rubber roller 16, the one-way damping shaft 26 and the L plate 14. The pressure index displayed by the force sensor 13 is transmitted to the display screen via radio, thereby obtaining the adhesive force between the tape and the enameled wire. The mechanical tape is applied, which is consistent with the tape application process of the enameled wire harness 7, to prevent errors caused by traditional manual tape application and mechanical tape application, and to ensure measurement accuracy and stability.

[0030] All technical features in this embodiment can be freely combined according to actual needs.

[0031] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
