Description

Technical Field

[0001] This utility model relates to a process for processing enameled wire, and more particularly to a device for removing the enamel coating. Background Technology

[0002] The description in this section provides only background information related to the disclosure of this utility model and does not constitute prior art.

[0003] The enameled wire inside the motor is used to wind the motor coil. The enameled layer serves both as insulation and must withstand various operating conditions such as high temperature, electromagnetic vibration, and mechanical stress. To ensure a good electrical connection between the enameled wire and terminals, solder joints, etc., the insulating enamel layer on the surface of the enameled wire usually needs to be removed during the production process. In the existing technology, mechanical enamel removal processes are widely used in motor production lines.

[0004] Currently, motor production lines typically produce multiple models and products on the same line, with significant differences in the diameter of the enameled wire between different products. When using mechanical stripping methods, the cutter head's structural dimensions must match the wire diameter to achieve a stable stripping effect. When production needs switch to enameled wires of different diameters, existing equipment often requires replacing the cutter head with a corresponding size; otherwise, incomplete stripping or damage to the conductor core may occur, affecting welding quality and product reliability. However, due to the variety of wire diameters and frequent changes, current mechanical stripping equipment cannot achieve adaptive adjustment of the cutter head size, resulting in poor equipment compatibility, long downtime for changeovers, and low production efficiency.

[0021] Please see Figure 1-7 This embodiment provides a paint removal device, which includes: The bracket 1 has a first end and a second end that are arranged opposite to each other along the axial direction; Adjustment mechanism 2, the adjustment mechanism 2 includes micrometer 21, adjustment frame 22, and rotating wheel 23. The micrometer 21 is fixed on the bracket 1. The telescopic end of the micrometer 21 is connected to the adjustment frame 22. The rotating wheel 23 is installed on the adjustment frame 22. The pushing mechanism 3 includes a pushing frame 31 and a push rod 32. A spring 33 is connected between the first end of the pushing frame 31 and the support 1. A slider 34 is provided on the pushing frame 31 and is embedded in a groove 11 on the support 1. The first end of the pushing frame 31 is provided with an inclined surface 311 that cooperates with the rotating wheel 23. The push rod 32 is fixed on the pushing frame 31. The rotating mechanism 4 includes a rotating pulley 41, a bearing housing 42, and a rotating flange 43. The rotating pulley 41 is installed at the first end of the bearing housing 42, and the rotating flange 43 is installed at the second end of the bearing housing 42. The rotating pulley 41 and the rotating flange 43 are connected in a driving connection. The bearing housing 42 is fixed on the bracket 1. Paint peeling mechanism 5 includes a handle 51, a rotating frame 52, a cutter head 53, and a connecting rod 54. The rotating frame 52 is connected to the rotating flange 43. The first end of the handle 51 is provided with a waist hole 511 that is axially outward from the first end to the second end. The middle section of the handle 51 is connected to the rotating frame 52 through a pivot hole 512. The cutter head 53 is installed at the second end of the handle 51. The first end of the connecting rod 54 is connected to the second end of the push rod 32. The second end of the connecting rod 54 is provided with a pin that is inserted into the waist hole 511.

[0022] Based on the above structure, in use, the paint removal device includes a first station and a second station. In the first station, the rotary wheel 23 of the adjusting mechanism 2 is pressed down by the micrometer 21, the push frame 31 of the pushing mechanism 3 slides towards the second end, the spring 33 is compressed, the push rod 32 pushes towards the second end, and the connecting rod 54 of the paint removal mechanism 5 drives the first end of the handle 51 to rotate inward, and the second end of the handle 51 drives the cutter head 53 to rotate outward. With multiple cutter heads 53 and the cutter heads 53 rotating outward, the diameter used to place the enameled wire between the multiple cutter heads 53 becomes larger, thus enabling the processing of larger-sized enameled wires. In the second working position, the roller 23 of the adjusting mechanism 2 is lifted by the micrometer 21, the spring 33 returns to its original position, the pusher 31 of the pushing mechanism 3 slides towards the first end, the push rod 32 returns to its original position towards the first end, and the connecting rod 54 of the enamel stripping mechanism 5 drives the first end of the tool handle 51 to rotate outward, while the second end of the tool handle 51 drives the cutter head 53 to rotate inward. Similarly, with multiple cutter heads 53 and the cutter heads 53 rotating inward, the diameter used to hold the enameled wire between the multiple cutter heads 53 becomes smaller, thus enabling the processing of smaller enameled wires. The axial reciprocating motion of the pin at the second end of the connecting rod 54 can compress the inner wall of the waist hole 511, thereby pushing the tool handle 51 to rotate.

[0023] In practical use, when the operator needs to adjust the angle of the cutter head 53, it is only necessary to rotate the micrometer 21 in the adjustment mechanism 2, so that the end of the micrometer 21 drives the adjustment frame 22 to move up and down, that is, the adjustment frame 22 drives the rotating wheel 23 to move up and down. During the up and down movement of the rotating wheel 23, it can push the inclined surface 311 on one side. Under rolling friction, due to the track connection between the push frame 31 and the bracket 1, and with the traction force of the spring 33, the push frame 31 can be displaced by a very small axial displacement. Through the above displacement, the push rod 32 connected to the push frame 31 adjusts the handle 51 in the paint peeling mechanism 5. With the help of the obliquely set waist hole 511 on the handle 51 and the rotating shaft hole 512 in the middle position, the axial movement of the push rod 32 can be converted into the rotation of the handle 51, and the position of the cutter head 53 at the second end of the handle 51 can be changed.

[0024] In actual operation, the rotating pulley 41, bearing chamber 42, and rotating flange 43 in the rotating mechanism 4 are configured as hollow structures along the axial direction. The push rod 32 passes through the rotating pulley 41, bearing chamber 42, and rotating flange 43 and is connected to the connecting rod 54. The rotating pulley 41 rotates axially under the traction of an external belt, driving the rotating flange 43 to rotate. This causes the rotating flange 43 to drive the rotating frame 52 at the second end to rotate, and ultimately drives the tool holder 51 connected to the rotating frame 52 to rotate, so that the tool head 53 peels off the paint during rotation. The rotating frame 52 is configured as a rotatable protective frame structure with a fixed axial position and connected to the bracket 1. The hollow structure design does not affect the reciprocating adjustment of the push rod 32 inserted within it.

[0025] Based on the solution of this utility model, the connecting rod 54 can drive the handle 51 to move through the coordination of the adjusting mechanism 2 and the pushing mechanism 3, thereby achieving high-precision adjustment of the size of the cutter head 53. Specifically, the adjusting mechanism 2 uses the micrometer 21 to drive the rotating wheel 23 to push the inclined surface 311 of the pushing frame 31 in the pushing mechanism 3 with a very small and stable path, which is ultimately converted into driving the swing of the handle 51 in the paint stripping mechanism 5. This fully utilizes the precision of the micrometer 21 to achieve precise adjustment of the position of the cutter head 53, making the paint stripping device applicable to various sizes of enameled wire.

[0026] Furthermore, such as Figure 8 As shown, the paint removal device also includes a debris collection device 6, which includes a debris chamber 61 and a suction pipe 62. The debris chamber 61 covers the paint removal mechanism, one end of the suction pipe 62 is connected to the debris chamber 61, and the other end is connected to an external vacuum cleaner. The debris chamber 61 in the debris collection device 6 can be fitted with a quick-release head for easy and quick emptying of debris and installation / removal. The debris chamber 61 can at least... Figure 1 The area shown is covered to cover most of the space except for the protruding part of the enameled wire, thus achieving the function of isolating waste.

[0027] The number of tool holders 51 is set to multiple, and the multiple tool holders 51 are arranged at intervals around the axial direction. The cutting head 53 and the connecting rod 54 correspond one-to-one with the tool holders 51. Figure 6 As shown in the figure, this embodiment is equipped with 3 blades 53, with each blade 53 spaced 120 degrees apart, which meets most peeling needs.

[0028] Furthermore, a rubber dust cover 55 is fitted over the second end of the tool holder 51 between the tool head 53 and the rotating flange 43. The dust cover 55 serves to protect the movable rotating frame 52 from dust, especially the tool holder 51 and the internal pivot hole 512, preventing debris from entering and clogging the adjustment of the tool holder 51.

[0029] The first end of the bracket 1 is provided with a guide rod 12, and the push frame 31 is provided with a mounting groove 35 corresponding to the guide rod 12. The spring 33 is installed in the mounting groove 35, and the guide rod 12 is connected to the spring 33. Specifically, when the push frame 31 reciprocates axially relative to the bracket 1, the slider 34 of the push frame 31 reciprocates relative to the slide groove 11 of the bracket 1, causing the guide rod 12 to move in and out of the mounting groove 35. In particular, when the guide rod 12 enters the mounting groove 35, the first end of the spring 33 forms a traction force on the push frame 31 to return to its original position, which allows the rotating wheel 23 to always be in contact with the inclined surface 311.
