Description

Technical Field

[0001] The invention relates to the technical field of enameled round wire painting, and in particular to a self-adjusting enameled round wire painting device. Background Art

[0002] The electrical and mechanical properties of enameled wires mostly depend on the quality of the insulating coating. Therefore, the painting process is one of the important processes in the production of enameled wires. There are many ways to paint, such as felt painting, mold painting, etc. With the development of technology and the market's increasingly high requirements for the quality of enameled wires, the mold painting process has gradually become the mainstream, which is more conducive to accurately controlling the outer diameter of the enameled wire, making the coating more uniform, and reducing problems such as paint film eccentricity. At the same time, mold painting is also suitable for high-viscosity, high-solid paints, saving solvents, reducing costs, and helping to reduce environmental pollution.

[0003] Mould painting is a painting method that uses a mould with a specific hole shape and size to scrape off the excess paint on the conductor to form a uniform paint film. During mould painting, the painted conductor passes through the mould, and the paint maintains a certain thickness by relying on the gap between the conductor and the core hole of the mould, and then is cured into a paint film through high-temperature baking. When the coated conductor passes through the mould with an enlarged aperture in turn, the required paint film thickness can be achieved, that is, multiple passes of repeated painting and baking, and the mould painting method requires high precision. In the actual production process, the positions of the front and rear wire wheels, the middle support guide wheel and the mould frame should be adjusted in a straight line to ensure that the mould can move freely in the mould frame during painting, so that the conductor can always be in the center position by using the static pressure formed by the paint between it and the core hole of the mould, so as to ensure that the paint film of the enameled wire is uniform and does not produce eccentricity.

[0004] That is, the traditional mold painting and painting device uses molds arranged according to the mold matching table, and the wires are inserted into the mold holes in turn. The front end of the mold is fixed in the slot of the mold frame until all the molds are inserted and the painting begins. However, during continuous production, the temperature of the entire painting area is relatively high, which will directly lead to the paint liquid drying to form a small amount of paint residue and the line shaking causing skewness and other multiple factors, causing the mold to be stuck in the mold frame slot, resulting in uneven painting and poor concentricity, resulting in hidden dangers in the quality of the enameled wire. For this reason, the present application proposes a solution. Summary of the invention

[0005] The purpose of the present invention is to provide a self-adjusting enameled round wire painting device, which is used to solve the problem of poor painting caused by mold tilting and jamming that easily occurs during the continuous production process of traditional mold painting.

[0006] The object of the present invention can be achieved by the following technical solutions: A self-adjusting enameled round wire painting device, including a painting die and a die holder. A positioning cylinder is sleeved outside the painting die. A control panel is embedded outside the positioning cylinder. An optoelectronic sensor and a displacement sensor are installed on the inner wall of the positioning cylinder. A self-driven rotation component for driving the painting die to rotate is installed outside the die holder;

[0007] The self-driven rotation component includes a connecting arc plate and a fixing plate sleeved outside the die holder. A self-driven gear ring is rotatably installed on the front side of the connecting arc plate and the fixing plate. A self-centering component for the painting die to float and center is installed on the front side of the self-driven gear ring;

[0008] The self-centering component includes adjusting plates spaced on the front side of the self-driven gear ring. A bevel gear is horizontally installed at the lower end of the adjusting plate. A side tooth plate meshing with the bevel gear is rotatably installed at the rear end of the positioning cylinder. A scroll groove is opened on the front side of the side tooth plate. A radial displacement rod seat embedded in the positioning cylinder is slidably installed through the scroll groove of the side tooth plate. A swinging fixed rod fitting the surface of the painting die is rotatably arranged at the lower end of the radial displacement rod seat.

[0009] Further set as: A motor one is installed at the upper end of one of the fixing plates. A rotating tooth meshing with the self-driven gear ring is installed at the output end of the motor one.

[0010] Further set as: Rotating grooves are opened on the front side of the connecting arc plate and the fixing plate. A rotating ring matching the rotating groove is installed at the rear end of the rotating tooth.

[0011] Further set as: Adjusting plates are fixedly installed at intervals on the front side of the self-driven gear ring. A motor two is installed at the upper end of the adjusting plate. The output end of the motor two is connected to the bevel gear.

[0012] Further set as: A slider matching the scroll groove is installed in the middle at the rear side of the radial displacement rod seat. A guiding hole corresponding to the adjusting plate is opened on the positioning cylinder. Guiding rods vertically matching the guiding hole are installed on both sides of the radial displacement rod seat.

[0013] Further set as: The radial displacement rod seat is in an "L" shape and coincides with the swinging fixed rod at the lower end. Front pressing blocks and rear pressing blocks are respectively installed at the front and rear ends of the swinging fixed rod. The lower ends of the front pressing blocks and the rear pressing blocks respectively fit the stepped surface of the painting die.

[0014] Further set as: A connecting ring fitting the rear end of the painting die is jointly installed on the inner ring side of a pair of die holders.

[0015] Further set as: A fixing ring connecting to the front side of the die holder is installed on the inner ring side at the rear end of the side tooth plate.

[0016] Further set as: a self - regulation module is arranged in the control panel, and the self - regulation module includes an azimuth detection unit, an offset analysis unit, a centering execution unit and a processor which are communicatively connected;

[0017] The azimuth detection unit is used to obtain the vertical and horizontal parameters during the painting of the enameled round wire. The vertical and horizontal parameters include the deflection angle of the painting die in the vertical direction and the deflection angle in the horizontal direction , which are obtained by jointly measuring with a photoelectric sensor and a displacement sensor, and are sent to the offset analysis unit by the processor for the evaluation of the longitudinal deviation value;

[0018] The offset analysis unit compares the received and with the preset standard value "0" in the processor, generates a control signal and sends it to the centering execution unit; the centering execution unit controls the start of relevant components according to the control signal.

[0019] The present invention has the following beneficial effects:

[0020] 1. In the present invention, on the one hand, by flexibly adjusting the self - centering component, the stable adjustment of the painting die in the radial direction is completed, so that the enameled round wire can complete the automatic suspension and centering actions during the wire inlet process, and then the painted round wire can be evenly painted, avoiding the problem of poor painting caused by the skew of the painting die resulting in wire jamming during the wire inlet. On the other hand, by intelligently and real - time monitoring the deflection information of the painting die during use and immediately sending a control signal to perform a correction action after deflection occurs; under the mutual cooperation of the two, the painting die can intelligently and reliably complete the even painting of the enameled round wire, avoiding the problem that the painting die gets stuck in the mold frame slot due to multiple factors such as the high temperature in the painting area during continuous production causing the paint liquid to dry and form a small amount of paint slag and the skew caused by the line jitter, resulting in limited quality of the enameled round wire due to uneven painting and poor concentricity;

[0021] 2. In the centering suspension adjustment, the radial movement process of the radial displacement rod seat is as follows: it is realized by the matching rotation of the rear slider and the spiral groove on the side tooth plate. Specifically, when the side tooth plate rotates, it drives the spiral groove to rotate circumferentially, and the radial displacement rod seat vertically slidably arranged on the positioning cylinder completes the spiral rotation and finally realizes the radial movement under the cooperation of the slider and the spiral groove. Further, the radial displacement rod seat makes the front pressing block and the rear pressing block on the swinging fixed rod form stable contact with the stepped surface of the painting die, achieving the purpose of suspending and centering the painting die;

[0022] 3. When applying paint to the enameled round wire, the enamelled round wire with paint passes through the paint application die. Relying on the gap between the enamelled round wire and the hole of the paint application die, the paint layer is maintained at a certain thickness, and the enamelled round wire is always in the center position of the paint application die. In addition, the self-driving gear ring is used to drive the positioning cylinder and the paint application die to rotate as a whole, and finally uniform painting is achieved.

Detailed Embodiments

[0034] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative work shall fall within the protection scope of the present invention.

[0035] Embodiment 1: Aiming at the problems of mold skew and jamming that easily occur in traditional mold painting during continuous production, which lead to poor painting, the following technical solutions are proposed:

[0036] Refer to Figure 1 - Figure 4 As shown in the figure, in this embodiment, a self-adjusting enameled round wire painting device includes a painting mold 2 and a mold frame 3. A positioning cylinder 1 is sleeved outside the painting mold 2, and a control panel is embedded outside the positioning cylinder 1. A photoelectric sensor and a displacement sensor are installed on the inner wall of the positioning cylinder 1, and the photoelectric sensor and the displacement sensor are communicatively connected to the control panel. A self-driving rotation assembly for driving the painting mold 2 to rotate is installed outside the mold frame 3;

[0037] Refer to Figure 4 - Figure 7 As shown in the figure, the self-driving rotation assembly includes a connecting arc plate 4 and a fixing plate 5 sleeved outside the mold frame 3. A self-driving gear ring 6 is rotatably installed on the front side of the connecting arc plate 4 and the fixing plate 5. A motor 14 is installed at the upper end of one of the fixing plates 5, and a rotating gear 22 meshing with the self-driving gear ring 6 is installed at the output end of the motor 14. A rotating groove 21 is formed on the front side of the connecting arc plate 4 and the fixing plate 5, and a rotating ring 25 matching the rotating groove 21 is installed at the rear end of the rotating gear 22;

[0038] When the motor 14 is started, the self-driving gear ring 6 is driven to rotate by the rotating gear 22, and the self-driving gear ring 6 drives the positioning cylinder 1 to rotate. Thus, the painting mold 2 located in the positioning cylinder 1 can also rotate. When painting the enameled round wire, the enamelled round wire with paint passes through the painting mold 2, and the paint layer maintains a certain thickness depending on the gap between the enamelled round wire and the painting mold hole, so that the enamelled round wire is always in the central position of the painting mold 2. In addition, the self-driving gear ring 6 drives the overall rotation of the positioning cylinder 1 and the painting mold 2, ultimately realizing uniform painting;

[0039] Refer to Figure 5 - Figure 9As shown in the figure, a self-centering component for suspending and centering the painting mold 2 is installed on the front side of the self-driving gear ring 6. The self-centering component includes a regulating plate 7 spaced on the front side of the self-driving gear ring 6. A bevel gear 17 is horizontally installed at the lower end of the regulating plate 7. A side tooth plate 8 meshing with the bevel gear 17 is rotatably installed at the rear end of the positioning cylinder 1. A scroll groove 12 is formed on the front side of the side tooth plate 8. A radial displacement rod seat 10 embedded in the positioning cylinder 1 is slidably installed through the scroll groove 12 on the side tooth plate 8. A swing fixed rod 11 fitting the surface of the painting mold 2 is rotatably arranged at the lower end of the radial displacement rod seat 10. Front pressing blocks 19 and rear pressing blocks 18 are respectively installed at the front and rear ends of the swing fixed rod 11. The lower ends of the front pressing blocks 19 and the rear pressing blocks 18 respectively fit the stepped surface of the painting mold 2.

[0040] Referring to Figure 2 - Figure 9 As shown in the figure, a connecting ring 9 fitting the rear end of the painting mold 2 is jointly installed on the inner ring side of a pair of mold frames 3. The connecting ring 9 is of a soft colloid structure. The painting mold 2 can complete deflection under the sole connection of the connecting ring 9, realizing the suspension and centering of the enameled round wire for feeding and painting. A fixing ring 23 connecting the front side of the mold frame 3 is installed on the inner ring side of the rear end of the side tooth plate 8. The regulating plates 7 are fixedly installed at intervals on the front side of the self-driving gear ring 6. A second motor 15 is installed at the upper end of the regulating plate 7. The output end of the second motor 15 is connected to the bevel gear 17.

[0041] It should be noted in combination with the above: When uniformly painting the enameled round wire, the painting mold 2 may be skewed during the feeding process of the enameled round wire. The self-centering component set here is to solve the above problem. Specifically, the second motor 15 is started to drive the side tooth plate 8 to rotate through the bevel gear 17. After the side tooth plate 8 rotates, it drives the radial displacement rod seat 10 to complete the radial movement relative to the positioning cylinder 1. At this time, the front pressing blocks 19 and the rear pressing blocks 18 on the swing fixed rod 11 outside the painting mold 2 complete the adaptive fitting of the stepped surface of the painting mold 2, and gradually drive the painting mold 2 to be suspended and centered in the positioning cylinder 1. Thus, the entire painting automatic adjustment action is completed. During the adjustment process, the enameled round wire follows the adjustment of the painting mold 2 and finally realizes uniform painting.

[0042] Referring to Figure 5 - Figure 7 As shown in the figure, a slider 13 matching the scroll groove 12 is installed in the middle of the rear side of the radial displacement rod seat 10. The positioning cylinder 1 is provided with a guide hole 24 corresponding to the regulating plate 7. Guide rods 16 vertically matching the guide hole 24 are installed on both sides of the radial displacement rod seat 10. The radial displacement rod seat 10 is in an "L" shape and the lower end coincides with the swing fixed rod 11.

[0043] It should be noted that when the radial movement rod seat 10 moves radially, it is realized by the rotation of the rear slider 13 matching with the scroll groove 12 on the side tooth plate 8. Specifically, when the side tooth plate 8 rotates, it drives the circumferential rotation of the scroll groove 12, while the radial movement rod seat 10 vertically slidably arranged on the positioning cylinder 1 completes the vortex rotation and finally realizes the radial movement under the cooperation of the slider 13 and the scroll groove 12. Further, the radial movement rod seat 10 enables the front pressing block 19 and the rear pressing block 18 on the swing fixed rod 11 to form stable contact with the stepped surface of the painting mold 2, achieving the purpose of suspending and centering the painting mold 2;

[0044] Basic principle: By flexibly adjusting the self-centering component, the stable adjustment of the painting mold 2 in the radial direction is completed, enabling the enameled round wire to automatically suspend and center during the wire feeding process, so that the round wire with paint can be evenly painted, avoiding the problem of poor painting caused by the skew of the painting mold 2 resulting in wire feeding jamming.

[0045] Embodiment 2: This embodiment further intelligently optimizes the self-centering process in Embodiment 1:

[0046] The control panel is communicatively connected to the second motor 15, and a self-adjustment module is arranged in the control panel. The self-adjustment module includes an orientation detection unit, an offset analysis unit, a centering execution unit, and a processor that are communicatively connected;

[0047] The orientation detection unit is used to obtain the vertical and horizontal parameters during the painting of the enameled round wire. The vertical and horizontal parameters include the deflection angle of the painting mold 2 in the vertical direction and the deflection angle in the horizontal direction, which are measured jointly by a photoelectric sensor and a displacement sensor and sent to the offset analysis unit for the evaluation of the vertical deviation value, as follows:

[0048] S1: The orientation detection unit obtains the deflection angle of the painting mold 2 in the vertical direction through the photoelectric sensor and the displacement sensor and the deflection angle in the horizontal direction , A negative value indicates that the painting mold 2 deflects to the left from the top-down detection state, a positive value indicates that the painting mold deflects to the right from the top-down detection state. Similarly, a positive value indicates that the painting mold 2 deflects forward from the side-view detection state, and vice versa a negative value indicates that the painting mold 2 deflects backward from the side-view detection state;

[0049] S2: Send and to the deflection analysis unit through the processor. The deflection analysis unit compares and with the standard value "0" respectively. If and If both are equal to 0, no signal is generated. If or ≠0, a control signal is generated and sent to the central execution unit;

[0050] S3: After receiving the control signal, the central execution unit immediately controls the second motor 15. The second motor 15 starts and drives the side gear plate 8 to rotate through the bevel gear 17. After the side gear plate 8 rotates, it drives the radial displacement rod seat 10 to complete the radial movement relative to the positioning cylinder 1. At this time, the front pressing block 19 and the rear pressing block 18 on the swing fixed rod 11 outside the painting die 2 complete the adaptive fitting to the stepped surface of the painting die 2, and gradually drive the painting die 2 to be suspended and centered in the positioning cylinder 1;

[0051] The advantages of the solution are as follows: By intelligently and real-time monitoring the deflection information during the use of the painting die 2 and immediately sending a control signal to perform a corrective action after deflection occurs, the enameled round wire can complete the automatic suspension and centering actions during the in-line painting process. Further, the round wire with paint can be evenly painted, avoiding the problem of poor painting caused by skewing and jamming during in-line feeding.

[0052] Embodiment 3: Combining Embodiment 1 and Embodiment 2, this embodiment constitutes a painting method for a self-adjusting enameled round wire, including the following steps:

[0053] Step 1: When painting the enameled round wire, the enameled round wire with paint passes through the painting die 2. Depending on the gap between the enameled round wire and the hole of the painting die, the paint layer maintains a certain thickness, so that the enameled round wire is always in the centered position of the painting die 2. The first motor 14 starts and drives the self-driving gear ring 6 to rotate through the rotating gear 22. The self-driving gear ring 6 drives the positioning cylinder 1 to rotate, and together with the above-mentioned self-centering corrective action, uniform painting is completed;

[0054] Step 2: In Step 1, if the painting die 2 is skewed, at this time, the photoelectric sensor and the displacement sensor immediately detect the deflection information and send a control signal to the second motor 15. The second motor 15 starts and drives the side gear plate 8 to rotate through the bevel gear 17. After the side gear plate 8 rotates, it drives the radial displacement rod seat 10 to complete the radial movement relative to the positioning cylinder 1. At this time, the front pressing block 19 and the rear pressing block 18 on the swing fixed rod 11 outside the painting die 2 complete the adaptive fitting to the stepped surface of the painting die 2, and gradually drive the painting die 2 to be suspended and centered in the positioning cylinder 1. The specific movement process of the radial displacement rod seat 10 is as follows: When the side gear plate 8 rotates, it drives the spiral groove 12 to rotate circumferentially. The radial displacement rod seat 10 vertically slidably arranged on the positioning cylinder 1 completes the spiral rotation and finally realizes the radial movement under the cooperation of the slider 13 and the spiral groove 12. Further, the radial displacement rod seat 10 enables the front pressing block 19 and the rear pressing block 18 on the swing fixed rod 11 to form a stable contact with the stepped surface of the painting die 2.

[0055] In summary, on the one hand, by flexibly adjusting the self-centering component, the stable adjustment of the painting die 2 in the radial direction is completed, enabling the enameled round wire to complete the automatic suspension and centering actions during the wire feeding process. As a result, the round wire with paint can be evenly painted, avoiding the problem of poor painting caused by the jamming of the wire feeding due to the skew of the painting die 2. On the other hand, by intelligently and real-time monitoring the deflection information of the painting die 2 during use and immediately sending a control signal to perform a corrective action immediately after deflection occurs. Under the mutual cooperation of the two, the painting die can intelligently and reliably complete the even painting of the enameled round wire, avoiding the jamming of the painting die 2 in the slot of the die holder 3 caused by multiple factors such as the high temperature in the painting area during continuous production, which leads to the air drying of the paint liquid to form a small amount of paint slag and the skew caused by the line shaking, resulting in the problem of limited quality of the enameled round wire due to uneven painting and poor concentricity.

[0056] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
