Description

Technical Field

[0001] The present invention relates to the technical field, and specifically to a thermal shock detection device for the production of H-class calcined mica tape enameled wire. Background Art

[0002] Mica belongs to rock-forming minerals and is a very good corona-resistant material. Therefore, mica is widely used in the high-voltage motor industry. However, calcined mica is obtained by calcining ordinary mica. The mica tape made of calcined mica has the advantage of more stable electrical properties. The H-class calcined mica tape is a mica tape using polyester film as the substrate, which has higher heat resistance. However, when using the calcined mica tape to produce enameled wire, there are many problems such as easy powder falling and reverse adhesion. In order to ensure the performance of the H-class calcined mica tape enameled wire itself, a thermal shock detection device is usually used to detect its performance.

[0003] However, most of the current thermal shock detection devices have the following problems:

[0004] First, during the detection process of the existing thermal shock detection devices, most of them require manual automatic feeding, which is not convenient for realizing automatic feeding, thus greatly increasing the labor force and at the same time reducing the working efficiency during thermal shock detection. Moreover, it is not convenient to effectively clean the impurities and dust adhering to the surface of the H-class calcined mica tape enameled wire during the feeding process.

[0005] Second, when the existing thermal shock detection devices perform thermal shock detection on the H-class calcined mica tape enameled wire, it is not convenient to simultaneously detect multiple H-class calcined mica tape enameled wires synchronously. At the same time, the overall extrusion and bending efficiency of the H-class calcined mica tape enameled wire during detection is relatively low, thus greatly reducing the practicality of the thermal shock detection device itself.

[0006] Therefore, we propose a thermal shock detection device for the production of H-class calcined mica tape enameled wire to solve the problems mentioned above. Summary of the Invention

All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figures 1-9, the present invention provides a technical solution: a thermal shock detection device for the production of H-class calcined mica tape electromagnetic wire, including a device body 1, a conveying pipe 2, a feeding port 3, a servo motor 4, a transmission rod 5, a disc 6, a moving frame 7, a pushing plate 8, a stopper 9, a pulley 10, a central rod 11, an incomplete gear 12, a movable frame 13, a positioning plate 14, a cleaning brush 15, a cover plate 16, a scroll spring 17, a heater 18, a connecting plate 19, an internal spring 20, a lapping block 21, an extrusion block 22, a roller rod 23, a guiding block 24, a guiding rod 25, a return spring 26, a clamping plate 27, a connecting spring 28, an electric telescopic rod 29, a vertical plate 30 and a fixing block 31. The left end of the device body 1 is fixedly installed with a conveying pipe 2, and a feeding port 3 is installed at the upper end of the conveying pipe 2. The back of the conveying pipe 2 is installed with a servo motor 4, and the output end of the servo motor 4 is installed with a transmission rod 5. The end of the transmission rod 5 is installed with a disc 6, and a moving frame 7 is installed on the disc 6. The right end of the conveying pipe 2 is installed with a cover plate 16, and a scroll spring 17 is installed between the upper end of the cover plate 16 and the conveying pipe 2. The inner side of the device body 1 is installed with a heater 18, and a connecting plate 19 is installed inside the device body 1. The lower end of the connecting plate 19 and the device body 1 are connected to each other through an internal spring 20, and a lapping block 21 is installed at the upper end of the connecting plate 19. An extrusion block 22 is installed inside the lapping block 21, and a roller rod 23 is fixedly installed at the lower end of the extrusion block 22. A guiding block 24 is installed on the roller rod 23, and a guiding rod 25 is installed at the end side of the guiding block 24. The upper end of the guiding rod 25 and the inside of the connecting plate 19 are connected to each other through a return spring 26, and a clamping plate 27 is installed on the outer side of the guiding rod 25, and a connecting spring 28 is installed at the lower end of the clamping plate 27. An electric telescopic rod 29 is fixedly installed inside the device body 1, and the outer end of the electric telescopic rod 29 is fixedly installed on the side of the vertical plate 30, and the outer side of the vertical plate 30 is fixedly connected to a fixing block 31.

[0031] The side of the disc 6 and the moving frame 7 are in sliding connection, and a pushing plate 8 is fixedly installed on the right side of the moving frame 7, and a stopper 9 is welded and installed at the upper end of the pushing plate 8. Moreover, the disc 6 and the transmission rod 5 are in key connection, and the transmission rod 5 and the central rod 11 are connected to each other through a pulley 10. The rotation of the disc 6 can make the moving frame 7 perform reciprocating motion left and right, and the movement of the moving frame 7 can drive the fixedly connected pushing plate 8 to perform synchronous reciprocating motion.

[0032] The central rod 11 and the transmission rod 5 are parallelly distributed, and an incomplete gear 12 is fixedly installed at the end of the central rod 11, and the incomplete gear 12 and the inside of the movable frame 13 are in meshing connection. The rotation of the transmission rod 5 can drive the central rod 11 to rotate synchronously under the action of the pulley 10, and the rotation of the central rod 11 can make the movable frame 13 perform reciprocating motion under the action of the incomplete gear 12.

[0033] There is a fixed connection between the side of the movable frame 13 and the positioning plate 14, and a sliding connection between the positioning plate 14 and the conveying pipe 2. A cleaning brush 15 is fixedly installed inside the positioning plate 14. The movement of the movable frame 13 can drive the positioning plate 14 to move synchronously. Through the movement of the positioning plate 14, dust and impurities on the surface of the workpiece can be cleaned under the action of the cleaning brush 15.

[0034] The connecting plates 19 are evenly distributed at equal intervals inside the device body 1, and a sliding connection structure is formed between the lower end side of the lowermost connecting plate 19 and the inside of the device body 1. By using the evenly distributed connecting plates 19, it is convenient to synchronously detect multiple workpieces.

[0035] Guide blocks 24 are installed on both the left and right side edges of the roller rod 23, and the guide blocks 24 are set in a right trapezoidal structure. The upper end of the guide block 24 is in mutual contact with the inner end of the guiding rod 25, and the contact surface between the guide block 24 and the inner end of the guiding rod 25 is set as an inclined side. The movement of the guide block 24 can extrude the end of the guiding rod 25 under the action of the inclined side.

[0036] The outer end of the guiding rod 25 is in mutual contact with the lower end side of the clamping plate 27. Both the guiding rod 25 and the clamping plate 27 form a sliding connection structure with the connecting plate 19, and the clamping plate 27 is symmetrically arranged about the vertical central axis of the connecting plate 19. The movement of the guiding rod 25 can extrude the lower end of the clamping plate 27, causing the clamping plate 27 to slide on the connecting plate 19.

[0037] The fixing blocks 31 are evenly distributed at equal intervals inside the vertical plate 30, and the fixing blocks 31 and the vertical plate 30 are of welded integrated structure. All the evenly distributed fixing blocks 31 are set in a right triangle structure, and all the fixing blocks 31 are arranged at the lower end of the roller rod 23. The movement of the vertical plate 30 can drive the fixing blocks 31 of the welded integrated structure to move synchronously.

[0038] Working principle: When using this thermal shock resistance detection device for H-class calcined mica tape electromagnetic wire production, first according to Figures 1-9As shown, place the H-class calcined mica tape electromagnetic wire into the interior of the feed port 3 on the conveying pipe 2. At this time, the H-class calcined mica tape electromagnetic wire is blocked by the stopper 9. Then, turn on the servo motor 4. The activation of the servo motor 4 enables the transmission rod 5 to rotate. The rotation of the transmission rod 5 enables the disc 6 to rotate synchronously. The rotation of the disc 6 enables the moving frame 7 to move reciprocally left and right. The reciprocating left and right movement of the moving frame 7 drives the push plate 8 and the stopper 9 to move synchronously. At the same time, the rotation of the transmission rod 5 enables the central rod 11 to rotate under the action of the pulley 10. The rotation of the central rod 11 enables the movable frame 13 to move reciprocally under the action of the incomplete gear 12. By utilizing the reciprocating movement of the movable frame 13, the positioning plate 14 can be made to move reciprocally synchronously. When the push plate 8 and the stopper 9 move to the left, the stopper 9 releases the blockage of the H-class calcined mica tape electromagnetic wire. At this time, the H-class calcined mica tape electromagnetic wire falls to the bottom of the conveying pipe 2. When the push plate 8 and the stopper 9 move to the right, the stopper 9 re-inserts into the interior of the feed port 3 to block the H-class calcined mica tape electromagnetic wire. When the push plate 8 moves to the right, it can push the H-class calcined mica tape electromagnetic wire that has fallen inside the conveying pipe 2 onto the overlapping block 21 and the extrusion block 22 at the upper end of the connecting plate 19 inside the device body 1. During the process of pushing the H-class calcined mica tape electromagnetic wire, by utilizing the moving positioning plate 14, the dust and impurities on the surface of the H-class calcined mica tape electromagnetic wire can be cleaned under the action of the cleaning brush 15. Thus, automatic feeding during the overall thermal shock detection process is realized;

[0039] As Figure 1 and Figures 6-9 shown, when the H-class calcined mica tape electromagnetic wire falls onto the overlapping block 21 and the extrusion block 22 at the upper end of the connecting plate 19, the connecting plate 19 is affected by gravity and moves downward until the H-class calcined mica tape electromagnetic wires are evenly placed on the uniformly distributed connecting plates 19. Then, the roller rods 23 at the lower ends of the respective connecting plates 19 drop onto the uniformly distributed fixed blocks 31 inside the vertical plate 30. Then, turn on the heater 18 and the electric telescopic rod 29. The activation of the heater 18 can increase the internal temperature. At the same time, the activation of the electric telescopic rod 29 can cause the vertical plate 30 to drive the fixed block 31 to move forward. The movement of the fixed block 31 can squeeze the roller rod 23 under the action of the right triangle. The roller rod 23 drives the extrusion block 22 to move upward. At the same time, when the roller rod 23 moves upward, it can squeeze the guiding block 24 under the action of the hypotenuse. At this time, the guiding block 24 moves outward. The movement of the guiding block 24 can squeeze the guiding rod 25. At this time, the guiding rod 25 moves downward. By utilizing the downward moving guiding rod 25 and the upward moving extrusion block 22, the H-class calcined mica tape electromagnetic wire can be squeezed and bent. By controlling the heater 18 to change the temperature inside the device body 1, the overall thermal shock detection can be completed.

Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
