Description

Technical Field

[0001] This invention relates to the field of enameled wire testing technology, and more specifically to a test device for efficiently testing the surface lubricant content of enameled wire. Background Technology

[0002] To improve the smoothness of the enameled wire surface, thereby improving its winding and embedding performance, lubricating oil is coated on the surface of the enameled wire. However, the amount of lubricating oil used needs to be comprehensively considered to balance the lubrication effect and the actual use. Too much lubricating oil on the surface of the enameled wire will cause lubricating oil to accumulate on the guide rollers, block mechanical holes and mold holes during use, and may even make the enameled wire sticky and unable to be used normally. Too little lubricating oil on the surface of the enameled wire will also cause phenomena such as winding breakage due to insufficient lubrication.

[0003] Referring to the relevant content in publication numbers CN110006791A and CN102998423A, the essence is to obtain the lubricating oil content by weighing, recording, cleaning, filtering, distilling, drying, and re-weighing. Each sample test takes approximately 3 hours and consumes a large amount of cleaning agent. The testing time is long, the experimental steps are cumbersome, and it involves a lot of manual calculation. Alternatively, an oil paper absorption method can be used. This method uses multiple layers of folded oil-absorbing paper as the adsorption medium, and mechanical pressure transfers the lubricating oil from the surface of the enameled wire into the fiber structure of the oil-absorbing paper. The higher the lubricating oil content, the more layers of oil-absorbing paper are penetrated. However, the actual process has the following problems:

[0004] 1. Oil-absorbing paper will absorb the lubricating oil on the surface of the wire. If the lubricating oil content on the surface of the wire is low, the penetration of the oil-absorbing paper will not be obvious, which may lead to missed detection and will further increase the degree of lack of lubricating oil on the surface of the wire.

[0005] 2. Manual testing is required for each test, making high-throughput automated testing impossible and unsuitable for the rapid sampling needs of large-scale production lines. The blotting paper also needs frequent replacement (typically every 50-100 tests), increasing time costs and consumable consumption.

[0006] 3. The effect is greatly affected by the number of folds of the oil-absorbing paper, the uniformity of the applied pressure, and the physical characteristics of the oil-absorbing paper.

[0007] In response to the above, the present invention proposes a solution. Summary of the Invention

[0008] The purpose of this invention is to provide an efficient testing device for testing the lubricating oil content on the surface of enameled wire. The single cleaning-weighing method for testing the lubricating oil content on the surface of enameled wire is time-consuming and cumbersome, while the oil paper absorption measurement method has significant limitations.

[0009] The objective of this invention can be achieved through the following technical solution: a test device for efficiently testing the lubricating oil content on the surface of enameled wire, comprising a cleaning chamber, a drying chamber, and a winding assembly arranged in sequence, with a length measuring assembly and a cutting assembly respectively arranged at the front position of the cleaning chamber and the middle position between the drying chamber and the winding assembly;

[0010] Multiple triangular rollers composed of wire clamping blocks are arranged along the width direction in the cleaning box. Each wire clamping block has a corresponding wire groove on its outer surface, and a water-permeable fabric is applied in the wire groove.

[0011] The enameled wire is cleaned in a cleaning box, dried in a drying box, and wound up by a winding assembly. The amount of winding in the winding assembly is obtained based on the length measuring assembly, and the oil content of the enameled wire is obtained based on the amount of winding.

[0012] An intermediate wire clamping sleeve for the corresponding enameled wire is set between the cleaning box and the drying box, and multi-line micro-control actions of the associated winding assembly are generated through the intermediate wire clamping sleeve.

[0013] The washing box and the drying box are further configured such that a water return port is provided on the lower side of both the washing box and the drying box, and a fan assembly is provided on the upper end of the drying box.

[0014] Further configuration: the triangular rollers are equidistantly arranged along the enameled wire traction direction and staggered vertically along the enameled wire traction position; the cross-section of the clamping block is an equilateral triangular arc surface, and the outer edge of the clamping block is a large arc surface and the triangular position is a large rounded corner.

[0015] A further configuration is provided: a gear drive assembly corresponding to one end of the triangular roller is provided on the outer wall of one side of the cleaning tank.

[0016] The setting is further configured such that the angles of the two triangular rollers set in the vertical direction are staggered, and the large rounded corner of one of the triangular rollers corresponds to the middle position of the large arc surface.

[0017] Further configuration: multiple clamping blocks are connected by screws, and a moving water ring is provided at the internal position of the clamping block corresponding to the wire groove. A water storage groove is formed between the outer surface of the moving water ring and the inner wall curved surface of the clamping block. The other end of the triangular roller is rotatably connected to the cleaning tank and is set as a water inlet.

[0018] Further configuration: the clamping block has multiple seepage ports corresponding to the water-permeable fabric between the corresponding wire groove and the water storage tank, and the moving water ring has a water outlet connected to the water storage tank on the upper outer wall of its central horizontal plane.

[0019] A further configuration is provided: a lever is installed on the lower outer wall of the moving water ring, and the lever forms a sliding connection with the surface of the water storage tank.

[0020] A further configuration is provided: a pressure sensor is installed at the upper end of the intermediate wire clamping sleeve, the pressure sensor transmission rod extends downward to the interior of the intermediate wire clamping sleeve and is fitted with a roller sleeve, and a pressure roller corresponding to the enameled wire is provided inside the roller sleeve.

[0021] The present invention has the following beneficial effects:

[0022] 1. The testing process for the lubricating oil content on the surface of enameled wire mainly uses the basic cleaning-weighing method. Specifically, the lubricating oil content is obtained by cleaning the lubricating oil on the surface of the enameled wire and then air-drying and weighing it. This invention improves on this method by adopting an automatic length measurement method and shortening the overall experimental operation steps and time through continuous cleaning-winding.

[0023] 2. The key content of this invention lies in the cleaning process performed in the cleaning box, which mainly uses a triangular roller formed by multiple clamping blocks. While maintaining directional rotation, the triangular roller adopts a non-circular rotation mode, which is different from the conventional roller shaft movement. The purpose is to extend the cleaning distance of the enameled wire and improve the removal rate of lubricating oil. More specifically, the clamping blocks are mainly in the shape of equilateral triangular arcs, which respectively limit their setting distance / height in the horizontal and vertical directions, as well as limit the initial angle of the upper and lower triangular rollers. The purpose is to further change the winding mode of the enameled wire to be tested during the cleaning process. Furthermore, the cleaning agent is continuously pumped in based on the clamping blocks, and the rotation mode of the triangular rollers is used to limit the amount of cleaning agent sprayed out.

[0032] The technical solution of the present invention will be clearly and completely described below with reference to the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example 1: Regarding the testing process of lubricating oil content on the surface of enameled wire, the simple cleaning-weighing method is time-consuming and cumbersome, while the oil paper absorption method has significant limitations, such as the oil-absorbing paper absorbing lubricating oil from the wire surface, the number of folds in the oil-absorbing paper, the uniformity of applied pressure, and the physical characteristics of the oil-absorbing paper. The following technical solution is proposed to address these issues:

[0034] Reference Figures 1-6 This embodiment of an efficient test device for testing the surface lubricating oil content of enameled wire includes a cleaning box 2, a drying box 3, and a winding assembly 5 arranged in sequence. A length measuring assembly 1 and a cutting assembly 4 are respectively arranged at the front position of the cleaning box 2 and the middle position between the drying box 3 and the winding assembly 5.

[0035] Multiple triangular rollers composed of wire clamping blocks 6 are arranged along the width direction in the cleaning box 2. Each wire clamping block 6 has a corresponding wire groove 12 on its outer surface, and a water-permeable fabric is applied in the wire groove 12.

[0036] The enameled wire is cleaned in the cleaning box 2, dried in the drying box 3, and wound up in the winding assembly 5. The winding amount in the winding assembly 5 is obtained according to the length measuring assembly 1, and the oil content of the enameled wire is obtained through the winding amount.

[0037] A corresponding intermediate wire clamping sleeve 8 is provided between the cleaning box 2 and the drying box 3. The intermediate wire clamping sleeve 8 generates multi-line micro-control action of the associated winding assembly 5. Water return ports are provided on the lower side of both the cleaning box 2 and the drying box 3, and a fan assembly is provided on the upper end of the drying box 3.

[0038] Basic structural principle: Based on the cleaning box 2 and the drying box 3, the enameled wire to be tested enters the cleaning box 2 and the lubricating oil on the surface of the wire is cleaned by the cleaning agent. After cleaning, the enameled wire to be tested enters the drying box 3 and the moisture on the surface of the wire is dried by the fan structure. Finally, the wire is continuously wound in the winding assembly 5.

[0039] The key content of this invention is as follows: When the enameled wire to be tested passes through the cleaning box 2 and the drying box 3 in sequence, the winding amount wound onto the winding assembly 5 is first obtained by the length measuring component 1. After the maximum winding amount is reached, it can be automatically cut by the cutting component 4. The specific structure of the length measuring component 1 and the cutting component 4 will not be described in detail in this invention. What needs to be noted is:

[0040] The winding assembly 5 consists of a take-up drum and a rotating base. The rotating base drives the take-up drum to rotate in an directional manner. The cleaned and dried enameled wire is tied to the take-up drum. After the maximum winding amount is completed, the total weight of the take-up drum is directly weighed. The theoretical weight is obtained by combining the length and density of the enameled wire with the weighed weight for calculation and comparison. Finally, the oil content of the lubricating oil on the surface of the enameled wire is obtained. This part is essentially a simplified test process through a continuous method.

[0041] The key aspect of this invention lies in the cleaning action performed by the cleaning tank 2, such as... Figure 2 As shown, the enameled wire to be tested will pass through each triangular roller. The water-permeable cloth in the triangular roller, together with the cleaning agent, removes the lubricating oil on the surface of the enameled wire. The cleaning water or residual water will eventually flow out from the bottom of the cleaning tank 2.

[0042] Example 2: Supplementary explanation of the movement pattern of the triangular roller in the cleaning box;

[0043] The triangular rollers are equidistantly arranged along the traction direction of the enameled wire and staggered vertically along the position of the enameled wire. The cross-section of the clamping block 6 is an equilateral triangular arc surface, with the outer edge of the clamping block 6 being a large arc surface and the triangular position being a large rounded corner. A gear drive assembly 10 corresponding to one end of the triangular roller is provided on one side of the outer wall of the cleaning tank 2. The angles of the two triangular rollers arranged vertically are staggered, with the large rounded corner of one triangular roller corresponding to the middle position of the large arc surface. Multiple clamping blocks 6 are connected... The wire clamping block 6 is connected by screws, and a moving water ring 11 is provided inside the wire groove 12. A water storage tank 16 is formed between the outer surface of the moving water ring 11 and the inner curved surface of the wire clamping block 6. The other end of the triangular roller is rotatably connected to the washing box 2 and is set as a water inlet. Multiple water seepage ports 13 corresponding to water-permeable fabrics are opened between the wire groove 12 and the water storage tank 16 of the wire clamping block 6. A water permeable port 14 connecting the water storage tank 16 is opened on the upper outer wall of the moving water ring 11 corresponding to the horizontal plane of its center.

[0044] Solution Description: Please refer to the following for details. Figure 2 and Figure 3 The number of wire clamping blocks 6 can be set according to the quantity of enameled wire, and they are assembled with screws. The triangular rollers formed by the wire clamping blocks are not a conventional circular structure. Figure 3 As shown, the triangular rollers have an equilateral triangular arc cross-section and are positioned vertically. The enameled wire passes exactly through two of the triangular rollers, while the reference... Figure 4 Explanation: A gear drive assembly 10 is installed on one side of the two vertically arranged triangular rollers. The gear drive assembly 10 is essentially two meshing gears. The motor structure drives one of the gears to mesh, while the other gear rotates in the opposite direction at the same speed, thereby driving the two vertically moving triangular rollers to rotate in a directional manner.

[0045] Furthermore, it is necessary to further restrict the setting direction of the triangular rollers:

[0046] S1: The diagonal angle of each triangular roller is 60°. In the initial state, the upper and lower triangular rollers are arranged as follows: Figure 3 Position settings, such as the diagonal positions of the upper and lower triangular rollers being vertically downward, but the diagonal position of the upper triangular roller contacting the enameled wire, and the middle position of the outer edge of the lower triangular roller contacting the enameled wire, then when the two triangular rollers rotate in opposite directions at the same speed, during the process of the upper triangular roller rotating from one diagonal position to the other diagonal position contacting the enameled wire, the contact process with the enameled wire is as follows: specifically, the contact force between the diagonal position of the triangular roller and the enameled wire is the greatest, followed by the contact force between the middle position of the outer edge of the triangular roller and the enameled wire at a "turning point," such as first decreasing to a certain value and then slowly returning to the maximum contact force, because the initial position is the middle position of the outer edge. The change in the contact force between the lower triangular roller and the enameled wire is different, specifically increasing first and then decreasing. The purpose is to ensure that the winding method of the enameled wire is changed during the rotation of the two triangular rollers;

[0047] S2: In conjunction with S1, it should also be noted that: a cleaning tank 2 contains three or more triangular rollers, and the height of each adjacent triangular roller along the horizontal direction differs, specifically as follows... Figure 3 As shown, the height of the first set of triangular rollers is higher than that of the second set of triangular rollers, the height of the second set of triangular rollers is lower than that of the third set of triangular rollers, and the position of the third set of triangular rollers is higher than that of the fourth set of triangular rollers, and so on. The purpose is to extend the contact cleaning distance between the enameled wire and the triangular rollers.

[0048] Example 3: Based on Example 2, the circulation process of the cleaning water inside the triangular roller is described:

[0049] A lever 15 is installed on the lower outer wall of the moving water ring 11. The lever 15 and the surface of the water tank 16 form a sliding connection. A pressure sensor 7 is installed at the upper end of the intermediate wire clamping sleeve 8. The transmission rod of the pressure sensor 7 extends downward to the inside of the intermediate wire clamping sleeve 8 and is installed with a roller sleeve 17. The roller sleeve 17 is equipped with a corresponding wire pressing roller 9.

[0050] This solution needs to be explained in conjunction with the technical content of Embodiment 2:

[0051] One end of the triangular roller is connected to a gear, while the other end is connected to a water inlet. The purpose is to continuously pump cleaning agent into the triangular roller, ensuring that the cleaning agent seeps out from the water inlet into the water-permeable fabric, and then the water-permeable fabric contacts the enameled wire to complete the cleaning action.

[0052] Because the triangular roller has upper and lower sides, and the contact positions between the triangular roller and the enameled wire are different, for the upper triangular roller, when the cleaning agent is pumped into it, as the liquid level rises, it can enter the water storage tank 16 through the permeator and finally seep out through the seepage port 13. However, the actual process is as follows:

[0053] The upper triangular roller: the moving water ring 11 slides with the triangular roller, and the lower part of the moving water ring is equipped with a paddle 15. On the one hand, it can serve as a counterweight for the moving water ring 11 to ensure that the moving water ring 11 is in a relatively stationary state relative to the triangular roller. On the other hand, it can also serve as a partition structure for the water tank 16 to ensure that the cleaning agent seeps out from the seepage port 13 in the upper part and flows along the wire groove to finally act on the enameled wire. It should be understood that the cleaning agent does not flow out from the seepage port 13 that contacts the enameled wire.

[0054] The lower triangular roller: To avoid wasting cleaning agent, it is ensured that the cleaning agent can only flow out from the seepage port 13 on the upper side, which is in contact with the enameled wire. Figure 5 Based on this, specifically, it restricts the location of the permeable outlet 14 and the position of the lever 15. Figure 5 The text primarily describes the internal structure of the upper triangular roller. For the lower triangular roller, the water inlet 14 can only be located directly above the moving water ring 11, while the installation angle of the lever 15 is larger. Figure 5 The installation range of the middle deflector 15 is approximately -30° to 30°, so the installation range of the middle deflector 15 of the lower triangular roller is approximately -120° to 120°.

[0055] The above solution is mainly used to reduce the consumption of cleaning agents.

[0056] Example 4: Combining Examples 2 and 3... Figure 6 Explanation:

[0057] Figure 6 The structure shown is mainly used to provide feedback on tension changes during the enameled wire cleaning process. Specifically, the display value in pressure sensor 7 is the primary indicator, while the preceding data is the resistance change of the enameled wire as it passes through the triangular roller. If there is lubricating oil on the surface of the enameled wire and the amount of lubricating oil is large or even excessive, the resistance during passage is relatively low. Therefore, when the traction speed of the winding assembly is relatively stable, the display value in pressure sensor 7 is relatively stable. Specifically, the display value in pressure sensor 7 is directly related to the resistance of the enameled wire as it passes through. The purpose of this is to control the pumping amount of cleaning agent in this way.

[0058] This embodiment is merely a supplement to Embodiments 1 to 3 and will not be explained further.

[0059] In summary, the testing process for lubricating oil on the surface of enameled wire mainly uses a basic cleaning-weighing method, but with the following differences: an automatic length measurement test method is adopted, and the main improvement is made to the cleaning process. This is achieved primarily by using a triangular roller composed of multiple clamping blocks, combined with the non-circular rotation of the triangular roller to extend the cleaning distance of the enameled wire. Specifically, this is done by changing the contact force between the clamping blocks and the enameled wire. Based on the above, the cleaning agent is further pumped into the triangular rollers positioned at the top and bottom, and the rotation direction of the two triangular rollers at the top and bottom limits the amount of cleaning agent sprayed out.
