Description

Technical Field

[0001] The present application relates to the field of mechanical testing equipment, and in particular to a device for testing the adhesion of an enameled wire surface tape. Background Art

[0002] In modern industrial production, enameled wire is widely used in various electrical equipment such as motors and transformers. In order to ensure the performance stability and reliability of enameled wire, the requirements for its surface treatment process are extremely strict. Especially for application scenarios where tape needs to be wrapped around the enameled wire, such as during the winding of the magnetic ring, the adhesion of the tape directly affects the quality and service life of the product. At present, the adhesion test of the tape on the surface of the enameled wire mainly relies on manual operation, and the adhesion is evaluated by the operator manually sticking and tearing off the tape. This method is not only time-consuming and labor-intensive, but also highly subjective, and it is difficult to form standardized data records.

[0003] To solve the above problems, existing methods include using a manual dynamometer for measurement, or using a simple mechanical device to simulate manual operation. The manual dynamometer is usually held by the operator, who sticks the tape on the enameled wire and then tears it off with force. The adhesion is determined by reading the value on the dynamometer. Another method is to use a simple mechanical device, such as a lever dynamometer, to measure the force of tearing off the tape through a fixed lever arm and a force sensor. Although these methods can meet basic needs to a certain extent, they have obvious deficiencies in accuracy and stability.

[0004] Therefore, there is an urgent need for a device that can automatically and accurately detect the adhesive force of the tape on the surface of the enameled wire to improve the accuracy and reliability of the test. Summary of the invention

[0005] In order to improve the accuracy and reliability of the test, the present invention provides a device for detecting the adhesive force of an enameled wire surface tape.

[0006] The present invention provides a device for detecting the adhesive force of an enameled wire surface tape, which adopts the following technical solution: A device for detecting the adhesive force of an adhesive tape on the surface of an enameled wire comprises a frame, the frame is connected with a display and a workbench, the display is configured to display the maximum value and the average value of the force, and the enameled wires are placed side by side on the workbench; A pressing device, comprising a driving member, a dynamometer and a mounting plate, wherein the driving member is connected to the frame, the dynamometer is connected to a driving shaft of the driving member, the mounting plate is connected to the dynamometer, and the dynamometer is electrically connected to the display; A support block, located above the enameled wire and connected to the mounting plate, capable of supporting the middle of the tape; A clamping device, connected to the mounting plate and capable of clamping the tape, the clamping device being disposed on both sides of the support block; A limiting component is located below the support block and connected to the workbench, the limiting component abuts against two ends of the enameled wire to fix the two ends of the enameled wire; When the pressing device drives the tape to contact the enameled wire, the dynamometer can detect the pressure applied to the mounting plate; when the pressing device drives the tape to separate from the enameled wire, the dynamometer can detect the tension applied to the mounting plate.

[0007] By adopting the above technical solution, when it is necessary to detect the adhesion of the tape on the surface of the enameled wire, the enameled wire is placed side by side on the workbench and the enameled wire is limited by the limit assembly, and then the two ends of the tape are clamped by the clamping device so that the middle of the tape is under the support block and the sticky surface of the tape is located on the side away from the support block. Next, the pressing device is started, and the driving part drives the dynamometer and the mounting plate to move downward, so that the tape gradually approaches and contacts the enameled wire until the dynamometer reaches the preset value, that is, at this time the tape is firmly attached to the multiple enameled wires side by side, and the driving part stops moving. Then, the driving part operates in the opposite direction, and the driving part drives the dynamometer and the mounting plate to move upward, so that the tape gradually detaches from the enameled wire. At this time, the dynamometer can detect the tension on the mounting plate, thereby obtaining the adhesion between the tape and the enameled wire. During the whole process, the display shows the maximum and average values ​​of the force in real time, which is convenient for users to intuitively understand the test results.

[0008] The device for detecting the adhesive force of the adhesive tape on the surface of the enameled wire can stably fix the adhesive tape and the enameled wire during the detection process, and the tension value is recorded in real time during the whole process, and a more accurate result is obtained through the maximum value and average value of the tension, thereby improving the accuracy and reliability of the test.

[0010] By adopting the above technical solution, in the process of fixing the tape, the sleeve is first disassembled, the two ends of the tape are respectively bonded to different sleeves, and then the sleeves are mounted on the corresponding shafts. The structural design of the clamping device enables the tape to be stably fixed on the sleeve, and it is convenient to replace tapes of different widths or materials, thereby improving the flexibility and scope of application of the detection device. At the same time, the cooperation between the mounting frame and the shaft ensures the overall stability of the clamping device; when installing the sleeve, the horizontal setting of the shaft ensures the horizontal placement of the tape, thereby reducing the possibility of the tape shifting during the detection process.

The frame 1 is fixedly connected with a display 11 and a workbench 12, and the display 11 is configured to display the maximum and average values ​​of the force in real time. A plurality of enameled wires arranged side by side are placed on the workbench 12. The pressing device 2 includes a driving member, a dynamometer 22 and a mounting plate 23, and the driving member is fixedly connected to the frame 1. The dynamometer 22 is fixedly connected to the driving shaft of the driving member, and the dynamometer 22 is electrically connected to the display 11. The mounting plate 23 is fixedly connected to the dynamometer 22. The support block 3 is fixedly connected to the bottom of the mounting plate 23 and can support the middle of the tape. The clamping device 4 is connected to the mounting plate 23 and can clamp the tape, and the clamping devices 4 are arranged on both sides of the support block 3. The limiting assembly 5 is connected to the workbench 12, and is used to limit the two ends of the enameled wire.

[0039] When the pressing device 2 drives the tape to approach the enameled wire, the dynamometer 22 can detect the pressure exerted on the mounting plate 23; when the pressing device 2 drives the tape to separate from the enameled wire, the dynamometer 22 can detect the tension exerted on the mounting plate 23.

[0040] When it is necessary to detect the adhesive force of the adhesive tape on the surface of the enameled wire, the enameled wire is placed side by side on the workbench 12 and the enameled wire is limited by the limit assembly 5, and then the two ends of the adhesive tape are clamped by the clamping device 4, so that the middle of the adhesive tape is below the support block 3, and the adhesive surface of the adhesive tape is located on the side away from the support block 3. Then the pressing device 2 is started, and the driving member drives the dynamometer 22 and the mounting plate 23 to move downward, so that the adhesive tape gradually approaches and contacts the enameled wire until the dynamometer 22 reaches the preset value, that is, at this time, the adhesive tape is firmly attached to the multiple enameled wires arranged side by side, and the driving member stops moving. Then, the cylinder 21 is reversed, and the driving member drives the dynamometer 22 and the mounting plate 23 to move upward, so that the adhesive tape gradually separates from the enameled wire. At this time, the dynamometer 22 can detect the tension on the mounting plate 23, thereby obtaining the adhesive force between the adhesive tape and the enameled wire. During the whole process, the display 11 displays the maximum value and average value of the force in real time, which is convenient for users to intuitively understand the test results, and at the same time, improves the accuracy and reliability of the test.

[0041] Reference Figure 2 The driving member can be a cylinder 21, an electric push rod, etc., and the cylinder 21 is selected in this embodiment.

[0042] When the cylinder 21 is used, the pressure value can be controlled by adjusting the gas pressure to ensure the accuracy of the detection. In this embodiment, the preset value when the adhesive tape is bonded to the enameled wire is 50N.

[0043] Reference Figure 2 The support block 3 is made of rubber, which is elastic and will produce a slight elastic deformation when the tape is bonded to the enameled wire, thereby improving the bonding effect between the tape and the enameled wire and reducing the wear on the tape.

[0044] Reference Figure 2 There are two groups of clamping devices 4, which are respectively arranged on both sides of the supporting block 3 to fix the two ends of the tape.

[0045] Reference Figure 2 The clamping device 4 includes a mounting frame 41, a shaft 42 and a sleeve 43. The mounting frame 41 is fixedly connected to the bottom of the mounting plate 23. The shaft 42 is horizontally arranged, and one end of the shaft 42 is fixedly connected to the mounting frame 41. The sleeve 43 is sleeved on the shaft 42 and slidably connected to the shaft 42. The bottom of the sleeve 43 is higher than the bottom of the support block 3. The end of the tape is bonded to the sleeve 43, and the side of the tape away from the support block 3 is the sticky surface.

[0046] In the process of fixing the tape, the sleeve 43 is first removed, the two ends of the tape are respectively bonded to different sleeves 43, and then the sleeves 43 are sleeved on their respective corresponding shafts 42. The structural design of the clamping device 4 enables the tape to be stably fixed on the sleeve 43, and at the same time it is convenient to replace tapes of different widths or materials, thereby improving the flexibility and applicability of the detection device.

[0047] Reference Figure 3 and Figure 4 The mounting frame 41 is connected to a fixing device 6, and the fixing device 6 includes a first fixing component 61 and a second fixing component 62. The first fixing component 61 and the second fixing component 62 are respectively arranged on both sides of the sleeve 43. When the first fixing component 61 and the second fixing component 62 are in contact with the sleeve 43, the sleeve 43 is fixed. The mounting frame 41 is connected to a control device 7 for controlling the fixing device 6 to disengage or fix the sleeve 43.

[0048] The first fixing assembly 61 and the second fixing assembly 62 are respectively disposed on two sides of the sleeve 43 , thereby ensuring the stability and reliability of the sleeve 43 on the shaft 42 .

[0049] Reference Figure 3 and Figure 4 The first fixing assembly 61 includes a first fixing frame 611, a first rotating shaft 612, a first pressure plate 613, a first torsion spring 614 and a first clamping plate 615. The first fixing frame 611 is fixedly connected to the top of the mounting frame 41. The first rotating shaft 612 is horizontally arranged and is rotatably connected to one end of the first fixing frame 611 away from the mounting frame 41. A first rotating block is fixedly connected to the first end of the first pressure plate 613. Two first rotating blocks are provided. Both of the two first rotating blocks are sleeved on the first rotating shaft 612 and are rotatably connected to the first rotating shaft 612. The first clamping plate 615 is fixedly connected to the second end of the first pressure plate 613. The first clamping plate 615 is arranged in an arc, and its center is close to the side where the shaft 42 is located.

[0050] Reference Figure 3 and Figure 4 The first torsion spring 614 is sleeved on the first rotating shaft 612 and is disposed between the two first rotating blocks. The first free end of the first torsion spring 614 is fixedly connected to the first fixing frame 611 , and the second free end is fixedly connected to the first pressing plate 613 .

[0051] When the control device 7 controls the first clamping plate 615 to move away from the sleeve 43, the first torsion spring 614 is in an open state. When the control device 7 controls the first clamping plate 615 to abut against the sleeve 43, the first torsion spring 614 enables the first pressure plate 613 to drive the first clamping plate 615 to approach and abut against the sleeve 43, and keeps the position of the first pressure plate 613 unchanged, thereby ensuring that the sleeve 43 will not move easily, thereby improving the stability of the tape and the reliability of the detection process.

[0052] Reference Figure 3 and Figure 4The second fixing assembly 62 includes a second fixing frame 621, a second rotating shaft 622, a second pressure plate 623, a second torsion spring 624 and a second clamping plate 625. The second fixing frame 621 is fixedly connected to the bottom of the mounting frame 41. The second rotating shaft 622 is horizontally arranged and is rotatably connected to one end of the second fixing frame 621 away from the mounting frame 41. A second rotating block is fixedly connected to the first end of the second pressure plate 623. Two second rotating blocks are provided. Both second rotating blocks are sleeved on the second rotating shaft 622 and are rotatably connected to the second rotating shaft 622. The second clamping plate 625 is fixedly connected to the second end of the second pressure plate 623. The second clamping plate 625 is arranged in an arc, and its center is close to the side where the shaft 42 is located.

[0053] Reference Figure 3 and Figure 4 The second torsion spring 624 is sleeved on the second rotating shaft 622 and is disposed between the two second rotating blocks. The second free end of the second torsion spring 624 is fixedly connected to the second fixing frame 621 , and the second free end is fixedly connected to the second pressing plate 623 .

[0054] When the control device 7 controls the second clamping plate 625 to move away from the sleeve 43, the second torsion spring 624 is in an open state. When the control device 7 controls the second clamping plate 625 to abut against the sleeve 43, the second pressure plate 623 can maintain a certain pressure under the action of the second torsion spring 624, so that the second clamping plate 625 is closely abutted against the sleeve 43, thereby ensuring that the sleeve 43 will not loosen or fall off due to the action of external forces, thereby improving the stability and reliability of the detection device. At the same time, this structural design is simple, easy to operate, and convenient for quickly replacing and adjusting the sleeve 43, thereby improving the detection efficiency.

[0055] Reference Figure 3 and Figure 5 , the control device 7 is arranged between the first fixing assembly 61 and the second fixing assembly 62.

The bottom of the groove of the first part is arranged horizontally, and the bottom of the groove of the second part is arranged obliquely, and is inclined downward from one end close to the second part to the other end. The second part is located on the side of the first part away from the mounting frame 41.

[0056] Reference Figure 5 The first end of the first guide rod 72 is fixedly connected to the mounting frame 41, and the second end is slidably connected to the first support plate 73. The first support plate 73 is vertically arranged, the top end of the first support plate 73 abuts against the first pressing plate 613, the bottom end extends into the control groove 711, and slidably abuts against the control block 71.

[0057] When placing the sleeve 43, push the sleeve 43 close to the control block 71. After the sleeve 43 abuts against the control block 71, continue to push the sleeve 43 to move the control block 71 toward the mounting frame 41 until the first support plate 73 enters the second part, and the first support plate 73 moves away from the first pressure plate 613. The restoring force of the first torsion spring 614 causes the first pressure plate 613 to move with the first support plate 73, thereby causing the first clamping plate 615 to abut against the sleeve 43.

[0058] Reference Figure 5 The first end of the second guide rod 74 is fixedly connected to the mounting frame 41, and the second end is slidably connected to the second support plate 75. The second support plate 75 is vertically arranged, and the bottom end of the first support plate 73 abuts against the second pressing plate 623, and the top end extends into the control groove 711 and slidably abuts against the control block 71. The first support plate 73 and the second support plate 75 are symmetrically arranged about the control block 71.

[0059] The sleeve 43 is continuously pushed to make the second support plate 75 enter the second portion, and the second support plate 75 moves away from the second pressure plate 623 . The second torsion spring 624 makes the second support plate 75 move toward following the second support plate 75 , so that the second clamping plate 625 abuts against the sleeve 43 .

[0060] Reference Figure 4 and Figure 6 A movable groove 411 is provided on the side wall of the mounting frame 41. The control rod 76 is arranged horizontally, and one end of the control rod 76 extends into the mounting frame 41 and passes through the movable groove 411. The push rod 77 is arranged in the movable groove 411 and is fixedly connected to the control rod 76. The control rod 76 is fixedly connected to the handle 8.

[0061] Reference Figure 3 and Figure 4 A slot 412 is provided on the side wall of the mounting frame 41, and a plurality of slots 412 are provided, and the plurality of slots 412 are arranged along the circumference of the control rod 76. The handle 8 is slidably connected with an insertion rod 81, which passes through the handle 8 and can be inserted into any slot 412 to fix the handle 8 to the mounting frame 41.

[0062] Reference Figure 3 , Figure 4 and Figure 5 In this embodiment, two slots 412 are provided. When the push rod 77 is located in the movable slot 411, the insertion rod 81 can be inserted into one slot 412 to fix the handle 8 to the mounting frame 41; the push rod 77 extends out of the movable slot 411 and pushes the control block 71 away from the mounting frame 41 until the first support plate 73 and the second support plate 75 enter the first part of the control slot 711, and the insertion rod 81 can be inserted into the other slot 412 to fix the handle 8 to the mounting frame 41.

[0063] The combined design of the control rod 76 and the push rod 77 allows the operator to quickly switch the fixing device 6 by simply rotating the control rod 76, thereby improving the operating convenience and working efficiency of the detection device.

[0064] Reference Figure 7 and Figure 8 The limiting assembly 5 includes a placement frame 51 and a fixing bolt 52. The placement frame 51 is a frame with a rectangular cross section and is arranged horizontally. The placement frame 51 is mounted on the enameled wires placed side by side. The four corners of the placement frame 51 are threadedly connected to the fixing bolts 52, and the fixing bolts 52 are threadedly connected to the workbench 12 to adjust the distance between the placement frame 51 and the workbench 12. The fixing bolts 52 can also fix the placement frame 51 to the workbench 12, and the operation is simple. At the same time, it is also convenient to disassemble the placement frame 51.

[0065] Reference Figure 7 and Figure 8 The inner diameter of the placement frame 51 is 2 cm larger than the length of the support block 3 so that the support block 3 can drive the tape to pass through the hollow part of the placement frame 51.

[0066] Reference Figure 1 and Figure 8 The device for detecting the adhesive force of the adhesive tape on the surface of the enameled wire further comprises an adjusting column 9, which is arranged horizontally, and the length direction of the adjusting column 9 is parallel to the length direction of the enameled wire. The length of the adjusting column 9 is greater than the length of the placing frame 51, and the adjusting column 9 abuts against the enameled wire and is used to arrange the enameled wire so that the enameled wire is closely arranged.

[0067] Reference Figure 1 and Figure 8 There are multiple adjustment columns 9, and the diameter of each adjustment column 9 is different, which can match enameled wires with different diameters, thereby enhancing the applicability of the device.

[0068] The use principle of the present application is as follows: when in use, first place a plurality of enameled wires side by side on the workbench 12, and arrange them by adjusting the column 9. Then connect the limit assembly 5 to the workbench 12, so that the placement frame 51 abuts against the enameled wire. Then remove the sleeve 43, adhere the two ends of the tape to different sleeves 43 respectively, and sleeve the sleeve 43 on the corresponding shaft rod 42, so that the middle of the tape is under the support block 3, and the sticky surface of the tape is located on the side away from the support block 3. Then slowly rotate the sleeve 43 to adjust the length of the tape, so that the tape is close to the support block 3. After the length of the tape is appropriate, push the sleeve 43 towards the mounting frame 41, so that the sleeve 43 drives the control block 71 to approach the mounting frame 41 together, until the fixing device 6 fixes the sleeve 43.

[0069] Then, start the cylinder 21, which drives the dynamometer 22, the mounting plate 23 and the support block 3 to be close to the placement frame 51 at a speed of 300 mm / min. Even if the tape is close to the enameled wire, when the tape does not touch the enameled wire, the pressure index displayed on the display 11 is 0. Until the dynamometer 22 reaches 50N, that is, at this time the tape is firmly attached to the multiple enameled wires side by side, and then the cylinder 21 stops moving. Then, the cylinder 21 operates in the opposite direction, and the cylinder 21 drives the dynamometer 22 and the mounting plate 23 to move upward at the same speed until the tape is separated from the enameled wire. At this time, the dynamometer 22 can detect the tension exerted on the mounting plate 23, thereby obtaining the bonding force between the tape and the enameled wire. During the whole process, the display 11 displays the maximum and average values ​​of the force in real time, so that the user can intuitively understand the test results.

[0070] The device for detecting the adhesion force of the adhesive tape on the surface of the enameled wire can stably fix the adhesive tape and the enameled wire during the detection process, and the tension value can be recorded in real time during the whole process. More accurate results can be obtained through the maximum and average values ​​of the tension, thereby improving the accuracy of the adhesion test.

[0071] The embodiments of this specific implementation method are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
