Description

Technical Field

[0001] The utility model relates to the technical field of enameled wire detection, in particular to a flat wire winding detection device. Background Art

[0002] After the enameled wire is painted, it needs to undergo quality inspection. The wire diameter and surface quality inspection can be completed online. Enameled wire is often used for winding coils. The paint film on the surface of the enameled wire is required to have a certain toughness so that the enameled wire will not crack at the bend corners of the coil. The enameled wire needs to be removed from the painting production line for separate bend inspection. The enameled wire paint bend angle detection equipment in the prior art is difficult to simulate the actual situation of enameled wire winding. For example, CN204314205U discloses a flat wire wide-side bend angle device. The flat wire 8 to be tested is clamped between the fixed mold 3 and the movable mold 4. The rotating handle 43 is rotated to make the movable mold positioning shaft 41 move in a circle with the positioning center hole 42 as the center, forcing the flat wire 8 to bend around the fixed mold positioning shaft 31. The flat wire is clamped and positioned by the fixed die and the movable die. No tension is applied to the flat wire. The bending angle of the flat wire when compressed is difficult to define and the flat wire cannot be bent into multiple circles. It is difficult to accurately judge the degree of cracking of the paint film at the bending corner of the flat wire, and the test results are not accurate enough. Utility Model Content

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0026] The following combination Figures 1 to 4 , describing a flat wire winding detection device according to an embodiment of the present utility model.

[0027] A flat wire winding detection device includes a winding drive motor 1, a winding square column 2, a tension shaft 3 and a tension controller 4. The winding drive motor 1 is drivingly connected to the winding square column 2, and the tension controller 4 is connected to the tension shaft 3. The end of the tension shaft 3 is provided with a spool mounting position 31, and the spool mounting position 31 corresponds to the position of the winding square column 2.

[0028] A wire end limiting column 21 is provided at the end of the winding square column 2.

[0029] The flat wire 01 winding detection device of the present invention applies a certain tension to the flat wire 01, and the flat wire 01 can be wound on the winding square column 2 with a fixed bending angle, which more accurately simulates the actual winding state of the flat wire 01. By observing the paint film state at multiple bending corners of the flat wire 01 on the winding square column 2, the flat wire 01 can be accurately judged. The flat wire 01 is simulated by having a certain tension on the flat wire 01. By observing the paint film state at the corner, it is possible to accurately judge whether the paint film is cracked and the degree of cracking, thereby improving the accuracy of detection.

[0030] Specifically, the tension controller 4 controls the rotation of the tension shaft 3, so that the flat wire 01 between the winding square column 2 and the spool mounting position 31 has tension, simulating the tension exerted on the flat wire 01 during actual winding, so that the flat wire 01 can be tightly wound on the winding square column 2, ensuring that the bending angle of the flat wire 01 is 90°.

[0031] In one embodiment of the present invention, baffles 22 are provided at both ends of the winding column 2. A clearance groove 221 is provided on the baffle 22. The thread end limiting column 21 is located on the outside of the baffle 22. The thread end of the flat wire 01 passes through the clearance groove 221 and is wound around the thread end limiting column 21, thereby fixing the thread end of the flat wire 01. The thread end fixing is simple and quick. Winding can be performed by turning on the winding drive motor 1 and the tension controller 4. For example, a plurality of clearance grooves 221 are provided at both ends of the baffle 22, which are suitable for flat wires 01 of different sizes, reducing the influence of the state of the winding column 2 on the thread end fixing operation of the flat wire 01.

[0032] Preferably, a handle 23 is provided at the end of the wire end retaining column 21. Operating the handle 23 allows the winding column 2 to rotate, facilitating the securing of the end of the flat wire 01. Further preferably, a cutting mechanism is provided on the side of the winding column 2 near the tension shaft 3. The cutting mechanism comprises an upper cutter, a lower cutter, and a cutting drive. The cutting drive is used to drive the upper cutter downward until it contacts the lower cutter, thereby cutting the flat wire 01 between the upper and lower cutters.

[0033] In one embodiment of the present invention, a fixed baffle 32 and a movable baffle 33 are provided at one end of the tension shaft 3, and the spool mounting position 31 is located between the fixed baffle 32 and the movable baffle 33;

[0034] A locking piece 34 is sleeved on the end of the tension shaft 3 , and the locking piece 34 abuts against the movable baffle 33 .

[0035] In this embodiment, the locking member 34 and the movable baffle 33 are removed, and the spool can be placed on the tension shaft 3. The movable baffle 33 is then installed, and the locking member 34 presses the movable baffle 33 against the end of the spool. This allows the spool to be positioned on the tension shaft 3, thereby applying tension to the flat wire 01 between the tension shaft 3 and the winding square column 2. For example, the end of the tension shaft 3 is provided with threads, and the locking member 34 has a threaded hole.

[0036] Furthermore, the other end of the tension shaft 3 and the tension controller 4 are respectively provided with a synchronous belt 41 wheel, and the two synchronous belt 41 wheels are provided with a synchronous belt 41. The synchronous belt 41 and the synchronous belt 41 wheels realize the control of the rotation of the tension shaft 3 by the tension controller 4, and the transmission reliability is high.

[0037] In one embodiment of the present invention, the flat wire 01 winding detection device further includes a chassis 5. The winding drive motor 1, tension shaft 3, and tension controller 4 are all located within the chassis 5, while the winding column 2 and the spool mounting position 31 are located outside the chassis 5. The chassis 5 is provided with a control panel 51, to which the winding drive motor 1 and the tension controller 4 are electrically connected. The chassis 5 protects the transmission components and improves operational safety. The control panel 51 can be used to control the speed of the winding motor and the tension of the tension controller 4, thereby achieving control of the winding speed and winding tension, making the flat wire 01 winding detection device suitable for detecting flat wires 01 of various specifications.

[0038] Furthermore, a mounting platform is provided in the chassis 5 , and the tension shaft 3 is mounted on the mounting platform via two bearings 52 . The tension shaft 3 is firmly mounted and rotates smoothly.

[0039] Other structures and operations of the flat wire winding detection device according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.
