Abstract
Description
Technical Field
[0001] This invention relates to the field of flat wire processing technology, and more particularly to a small flat wire coating equipment. Background Technology
[0002] Flat wire, due to its wide and thin cross-section, excellent conductivity, and high filler content, is widely used in the manufacturing of motor windings, transformer coils, and precision electromagnetic wires. Before entering the coating process, flat wire must undergo thorough surface cleaning and drying to ensure that the paint adheres evenly and forms a dense, continuous paint film. Therefore, the cleaning effect directly affects the coating quality and the performance of the finished product.
[0003] Existing cleaning methods mostly use fixed brush rollers, unidirectional vibration mechanisms, or spraying for surface treatment. Their cleaning effect is mainly concentrated on the upper and lower surfaces of the flat wire. However, the left and right side walls of the flat wire are often difficult to clean thoroughly due to limited contact angle, insufficient adhesion, and fixed stroke of the cleaning elements. At the same time, the surface of the flat wire often has oil stains, oxide layers, or micro-groove structures, and the side wall areas are particularly difficult to reach, resulting in incomplete cleaning and affecting the uniformity and adhesion of subsequent drying and coating.
[0004] In view of this, the present invention proposes a small flat wire coating device to solve the problems existing in the prior art. Summary of the Invention
[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a small flat wire coating device.
[0006] To achieve the above objectives, the present invention adopts the following technical solution:
[0007] A small flat wire coating device includes a cleaning box, a drying box, and a coating box arranged sequentially. A cleaning cylinder is fixedly connected to the cleaning box, and each end of the cleaning cylinder has an opening (I) on its outer wall. The upper and lower outer walls of the cleaning cylinder also have openings (II), which are staggered with the openings (I). Fixed blocks are fixedly connected to the inner walls of both openings (I and II), and each fixed block has a through hole in its center. A moving cavity is coaxially formed in the center of each through hole, and a moving disc is slidably connected inside the moving cavity. Multiple vibrating springs are fixedly connected between the moving disc and the moving cavity. A telescopic mechanism is installed in the center of the moving disc, and a rubbing plate is installed at each telescopic end of the telescopic mechanism. A rubbing sponge is installed on the rubbing plate. A rubbing motion drive mechanism is installed inside the cleaning box, which connects to and drives the multiple moving discs, thereby causing the rubbing sponge on the rubbing plate to perform irregular rubbing.
[0008] Furthermore, the kneading motion drive mechanism includes a fixed plate, on which a drive cylinder is rotatably connected, and the axis of the drive cylinder is coaxial with the axis of the washing cylinder. A bevel gear is fixedly connected to one outer wall of the drive cylinder.
[0009] Furthermore, a transmission wheel is fixedly connected to the outer wall of the other side of the drive cylinder, and a drive motor is provided above the drive cylinder. A transmission wheel is fixedly connected to the output shaft end of the drive motor, and a transmission belt is sleeved on the outer wall of the transmission wheel and the transmission wheel.
[0010] Furthermore, one side of the bevel gear is provided with multiple drive shafts that are rotatably connected to the cleaning cylinder, and one end of each drive shaft is fixedly connected to a bevel gear two that meshes with the bevel gear one. The other end of each drive shaft is fixedly connected to a drive disc, and a push-pull plate is hinged between the drive disc and the corresponding telescopic mechanism.
[0011] Furthermore, the telescopic mechanism includes a fixed cylinder, an electromagnet is installed on the inner wall of one end of the fixed cylinder, and a telescopic rod is slidably connected to the other end of the fixed cylinder. A magnetic plate is fixedly connected to one end of the telescopic rod, and a connecting spring is provided between the magnetic plate and the electromagnet. Each kneading board is fixedly connected to the other end of the corresponding telescopic rod.
[0012] Furthermore, each rubbing board has a cavity inside, and its outer wall facing the rubbing sponge has multiple water outlets that communicate with the cavity for spraying cleaning agent onto the rubbing sponge.
[0013] Furthermore, the outer wall of the cleaning cylinder is equipped with a pipe, and a delivery pipe is provided between the pipe and the cavity. The cleaning agent provided by external equipment can be delivered through the pipe and the delivery pipe and finally injected into the cavity.
[0014] Furthermore, positioning plates are fixedly connected to the outer walls of the two fixed blocks in the first port, and pressing plates are installed on the telescopic mechanisms of the two fixed blocks. An airbag is provided between the pressing plate and the positioning plate.
[0015] Furthermore, both airbag outlets are connected to air supply pipes, and the two air supply pipes are positioned above and below each other and are fixedly connected to the cleaning cylinder via a fixing plate. Multiple jet nozzles are evenly spaced on the outer walls of the two air supply pipes.
[0016] The beneficial effects of this invention are as follows:
[0017] By combining airbag blowing, sponge circumferential flexible rubbing, and dynamic replenishment of cleaning agent to form a synergistic cleaning mode, it can first remove floating dust and then deeply peel off stubborn stains, achieving efficient, uniform, and non-destructive cleaning of the flat wire surface, providing a clean and reliable surface condition for subsequent painting.

[0027] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.
[0028] Reference Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 As shown, a flat wire coating device includes a cleaning box 1, a drying box 2, and a coating box 3 arranged in sequence. The flat wire enters the above three functional modules in sequence under the guidance of an external wire loosening device, and is finally collected by a winding device.
[0029] A cleaning cylinder 5 is fixedly connected to the cleaning tank 1. The outer walls at both ends of the cleaning cylinder 5 have openings 25, and the outer walls at the top and bottom of the cleaning cylinder 5 have openings 26, which are staggered with the openings 25. Fixing blocks 19 are fixedly connected to the inner walls of both openings 25 and 26. Each fixing block 19 has a through hole 29 in its center. A moving cavity 28 is coaxially formed in the center of the through hole 29, and a moving disc 31 is slidably connected inside the moving cavity 28. The moving disc 31 and the moving cavity 28 are elastically connected by multiple vibrating springs 27. The motion disc 31 can achieve multi-directional random disturbance within the motion cavity 28. A telescopic mechanism is installed in the middle of the motion disc 31. Each telescopic end of the telescopic mechanism is equipped with a rubbing plate 21, and the outer side of the rubbing plate 21 is covered with a rubbing sponge 39, so that the rubbing sponge 39 can form a large area of flexible contact with the surface of the flat wire. When the flat wire passes through the cleaning box 1, it also passes through the cleaning cylinder 5. When the telescopic mechanism is not powered on, it provides flexible clamping force through the connecting spring 33, so that the rubbing sponge 39 is located on the upper, lower and left and right side walls of the flat wire, forming a full circumferential covering contact surface.
[0030] The cleaning tank 1 is equipped with a kneading motion drive mechanism, which is connected to and drives multiple motion discs 31, thereby causing the kneading sponge 39 on the kneading plate 21 to perform irregular kneading.
[0031] The flat wire is fed through the washing box 1, drying box 2, and painting box 3 by an external unloading device, and finally collected by a winding device. The flat wire passing through the washing box 1 passes through the washing cylinder 5 at the same time. Under the action of multiple telescopic mechanisms, the rubbing sponges 39 on each rubbing plate 21 are pressed tightly against the upper and lower outer walls and side walls of the flat wire. When the flat wire is being conveyed, the rubbing motion drive mechanism is activated at the same time, which pushes and pulls the telescopic mechanism. With the cooperation of multiple vibrating springs 27, the moving disc 31 carries the telescopic mechanism in the moving cavity 28 to perform irregular rubbing motion, so that the rubbing sponges 39 on the rubbing plate 21 rub the surface of the flat wire. Through the staggered arrangement of the rubbing sponges 39, the upper, lower and side surfaces of the flat wire are cleaned simultaneously. The irregular rubbing motion, combined with the elastic buffer of the vibrating springs 27, allows the rubbing sponges 39 to closely adhere to the tiny bumps and depressions on the surface of the flat wire, achieving dynamic and flexible scrubbing of stubborn stains, overcoming the problem of incomplete cleaning by traditional unidirectional or vibration cleaning.
[0032] Reference Figure 3 As shown, as a further embodiment of the present invention, the kneading motion drive mechanism includes a fixed plate 4, a drive cylinder 6 is rotatably connected to the fixed plate 4, and the axis of the drive cylinder 6 is coaxial with the axis of the washing cylinder 5. A bevel gear 11 is fixedly connected to one side of the outer wall of the drive cylinder 6.
[0033] Reference Figure 3As shown, as a further embodiment of the present invention, a transmission wheel 7 is fixedly connected to the outer wall of the other side of the drive cylinder 6, and a drive motor 10 is provided above the drive cylinder 6. A transmission wheel 9 is fixedly connected to the output shaft end of the drive motor 10, and a transmission belt 8 is sleeved on the outer wall of the transmission wheel 7 and the transmission wheel 9. When the drive motor 10 is started, the transmission wheel 9 drives the transmission belt 8 to drive the transmission wheel 7 to rotate, thereby causing the drive cylinder 6 and the bevel gear 11 on its outer wall to rotate synchronously.
[0034] Reference Figure 4 As shown, as a further embodiment of the present invention, a plurality of drive shafts 16 rotatably connected to the washing cylinder 5 are provided on one side of the bevel gear 11, and a bevel gear 15 meshing with the bevel gear 11 is fixedly connected to one end of each drive shaft 16. A drive disk 17 is fixedly connected to the other end of each drive shaft 16, and a push-pull plate 18 is hinged between the drive disk 17 and the corresponding telescopic mechanism. Since the bevel gear 15 on each drive shaft 16 meshes with the bevel gear 11, when the bevel gear 11 rotates, through the cooperation with the bevel gear 15, each drive shaft 16 can rotate with the drive disk 17. The drive disk 17 drives the corresponding moving disk 31 through the hinged push-pull plate 18, so that the moving disk 31 realizes multi-directional and irregular reciprocating oscillation in the moving cavity 28, thereby driving the rubbing plate 21 and the rubbing sponge 39 to perform irregular rubbing actions.
[0035] Reference Figure 7 As shown, as a further embodiment of the present invention, the telescopic mechanism includes a fixed cylinder 30, an electromagnet 34 is installed on the inner wall of one end of the fixed cylinder 30, and a telescopic rod 32 is slidably connected to the other end of the fixed cylinder 30. A magnetic plate 35 is fixedly connected to one end of the telescopic rod 32, and a connecting spring 33 is provided between the magnetic plate 35 and the electromagnet 34. Each kneading board 21 is fixedly connected to the other end of the corresponding telescopic rod 32.
[0036] Before the flat wire is inserted, the electromagnet 34 is energized to generate attraction, which attracts the magnetic plate 35 to move towards the electromagnet 34. The connecting spring 33 is compressed, causing the telescopic rod 32 to retract into the fixed cylinder 30, thereby pulling open the rubbing sponge 39 to form a sufficient gap for wire insertion.
[0037] After the flat wire passes through, the electromagnet 34 is de-energized, the connecting spring 33 rebounds, causing the telescopic rod 32 to extend outward, so that the kneading sponge 39 is pressed tightly against the surface of the flat wire again. This mechanism has good flexibility and cushioning while maintaining the adhesion force, and can automatically adapt to the slight size difference of the flat wire.
[0038] Reference Figure 8 As shown, as a further embodiment of the present invention, each rubbing board 21 has a cavity 36 inside, and its outer wall facing the rubbing sponge 39 has a plurality of water outlet holes 38 communicating with the cavity 36 for spraying cleaning agent onto the rubbing sponge 39.
[0039] Reference Figure 4 , Figure 8 As shown, as a further embodiment of the present invention, a pipe 20 is installed on the outer wall of the cleaning cylinder 5, and a delivery pipe 37 is provided between the pipe 20 and the cavity 36. The cleaning agent provided by the external equipment can be delivered through the pipe 20 and the delivery pipe 37 and finally injected into the cavity 36. Then, the cleaning agent is sprayed into the rubbing sponge 39 through multiple water outlets 38 on the cavity 36. Thus, when the rubbing plate 21 carries the rubbing sponge 39 to clean the surface of the flat wire, the cleaning agent can be replenished and dynamically wetted in real time during the cleaning process, so that chemical cleaning and mechanical rubbing can work synchronously and synergistically. This not only significantly improves the cleaning efficiency and decontamination effect, but also ensures the precise control of the amount of cleaning agent and the continuity of the operation.
[0040] Reference Figure 4 As shown, as a further embodiment of the present invention, positioning plates 12 are fixedly connected to the outer walls of the fixing blocks 19 in both openings 25, and pressing plates 14 are installed on the telescopic mechanisms of both fixing blocks 19. An air bladder 13 is provided between the pressing plate 14 and the positioning plate 12, and the air bladder 13 is used to store air. When the rubbing motion drive mechanism causes the moving disc 31 to shake irregularly with the telescopic mechanism, the telescopic mechanism will repeatedly squeeze the air bladder 13 through the pressing plate 14, causing the air bladder 13 to repeatedly absorb and expel gas.
[0041] Reference Figure 4 As shown, as a further embodiment of the present invention, both airbags 13 are connected to air supply pipes 24 at their air outlets, and the two air supply pipes 24 are positioned above and below each other and are fixedly connected to the cleaning cylinder 5 via a fixing plate 23. Multiple jet nozzles 22 are evenly spaced on the outer walls of the two air supply pipes 24, and the discharged gas enters the air supply pipes 24 and is finally sprayed out through the multiple jet nozzles 22, thereby achieving synchronous and automatic blowing and cleaning of the flat wire surface.
[0042] Working principle: Under the action of the external wire feeding device, the flat wire first enters the cleaning box 1 and passes through the cleaning cylinder 5. As the flat wire enters the cleaning cylinder 5, before the rubbing motion drive mechanism drives the rubbing sponge 39 to press against the flat wire, the irregular swing of the telescopic mechanism causes the pressing plate 14 to form an initial periodic compression on the airbag 13. After repeated compression, the airbag 13 delivers the internal air through the air supply pipe 24 to multiple air jets 22. The pulsed airflow ejected from the air jets 22 first performs a pre-blowing of the outer surface of the flat wire, which can quickly remove floating dust, powder, fiber fragments and loose stains from the surface of the flat wire, and prevent light impurities from being pressed into the concave parts of the flat wire during the subsequent sponge pressing process. After the pre-blowing process is completed, each telescopic mechanism is driven by the elastic rebound after the electromagnet 34 is de-energized, so that the telescopic rod 32 extends outward, thereby allowing the rubbing sponges 39 on the multiple rubbing plates 21 to respectively adhere to the upper, lower and side walls of the flat wire, forming a full circumferential covering contact.
[0043] At this time, the kneading motion drive mechanism is activated. The drive motor 10 drives the transmission wheel 9 to rotate and drives the transmission wheel 7 and drive cylinder 6 to rotate through the transmission belt 8, so that the bevel gear 11 on the outer wall of the drive cylinder 6 produces a continuous and stable rotational motion. The bevel gear 11 meshes with multiple bevel gears 15, so that the circumferentially distributed drive shafts 16 achieve synchronous rotation. The rotation of the drive shaft 16 further drives the drive disk 17 fixedly connected to it to rotate synchronously. The drive disk 17, through the push-pull plate 18 hinged on its outer side, periodically applies push-pull force to each moving disk 31, so that the moving disk 31 produces a disturbance-like offset in multiple directions inside the moving cavity 28. The shaking spring 27 is compressed or stretched during the offset of the moving disk 31 and provides elastic reverse force in the return stroke, so that the moving disk 31 forms a continuous, irregular, multi-axial composite motion in the cavity, thereby making the kneading board 21 and the kneading sponge 39 produce a composite kneading trajectory of "random offset + elastic vibration".
[0044] This composite rubbing motion enables the rubbing sponge 39 to not only follow the contact along the length of the flat thread, but also to form multi-directional adhesion and rubbing around the flat thread. This allows the rubbing sponge 39 to actively enter the tiny grooves, edges, or curved surfaces on the flat thread surface, achieving flexible and dynamic deep cleaning. At the same time, the cleaning agent continuously supplied by the cavity 36 and the water outlet 38 continuously penetrates into the interior of the rubbing sponge 39, giving the rubbing sponge 39 a chemical dissolving effect while mechanically rubbing. This effectively removes the adhering dirt, oil film residue, and small stubborn particles that the preceding airflow has not completely removed, forming a two-stage synergistic cleaning effect of "airflow initial cleaning + sponge deep cleaning".
[0045] After completing the dynamic cleaning process of full-circumferential rubbing, soaking, and blowing, the flat wire continues forward into the drying chamber 2, where it is heated and dried. Subsequently, the flat wire enters the coating chamber 3, where it is coated with paint, and finally wound up by the winding device. The entire cleaning stage is achieved through the synergistic action of four factors: the multi-directional flexible contact of the rubbing sponge 39, the random disturbance motion of the drive system, the dynamic soaking of the cleaning agent, and the pre-blowing action formed by the airbag 13. This results in a highly efficient, deep, and uniform surface cleaning effect for the flat wire, providing a clean, dry, and residue-free surface foundation for subsequent painting processes.
[0046] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
