Description

Technical Field

[0001] This utility model relates to the field of coil stripping, and in particular to a three-sided stripping rotary fixture. Background Art

[0002] In the manufacturing process of inductors, three-sided paint stripping is typically performed using a three-sided paint stripping machine. For example, a rotary three-sided paint stripping machine, authorized in Announcement No. CN116914534A (October 20, 2023), includes a paint stripping UV laser module and a rotary table. The UV laser module is located on one side of the rotary table. The UV laser module includes a side paint stripping mechanism and a front paint stripping mechanism. After the side paint stripping mechanism strips one side, the product rotates 180°, and the side paint stripping mechanism strips the paint on the other side. After stripping two sides, the rotary table rotates, bringing the product into the front paint stripping mechanism for top paint stripping. This equipment cannot perform three-sided paint stripping at a single station and requires two separate stripping machines, resulting in a large footprint and high cost. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, the purpose of this utility model is to provide a three-sided stripping rotary fixture that has a small footprint, low cost, and can strip the coating from three sides of a coil.

[0004] To achieve the above objectives, one technical solution adopted by this utility model is: a three-sided paint-peeling rotary fixture, including a support base, multiple parallel support rods rotatably mounted on the support base, each support rod having a coil placement slot, each support rod having a hollow structure, and a magnetic strip installed inside the support rod, the magnetic strip being able to move along the thickness direction within the support rod, the multiple support rods being driven to rotate synchronously by a servo motor, a lifting cylinder being fixed on the support base, and multiple push rods being mounted on the telescopic shaft of the lifting cylinder, when the support rod rotates to the point where the coil placement slot faces downwards, the multiple push rods can pass through the support rods and push the magnetic strip away from the coil placement slot, and a collection bucket is located below the support rods.

[0005] The beneficial effects of this utility model's three-sided paint-stripping rotary fixture are as follows: multiple inductors to be peeled are transported to the coil placement slots of multiple support rods. The top of the coil and the two sides to be peeled are exposed outside the coil placement slots and are held in place by magnetic strips to prevent them from falling out. A servo motor drives multiple support rods to rotate synchronously, so that the top surface and the two sides rotate to a paint-stripping machine, thereby realizing the three-sided paint-stripping operation of the coil. The structure is compact, occupies a small area, and is low in cost when equipped with a paint-stripping machine. After the paint is peeled, the support rods rotate so that the coil placement slots face down, and the lifting cylinder drives the top rod to move upward. The top rod passes through the support rods and pushes the magnetic strips away from the coil placement slots. The coil placement slots no longer attract multiple coils, and the multiple coils fall into the collection bucket below for collection.

[0006] Preferably, multiple top-feeding rods are symmetrically arranged on the lifting platform. A through hole corresponding to the collection bucket is provided in the center of the lifting platform, and each end of the lifting platform is connected and fixed to a lifting cylinder. The lifting platform synchronously drives the multiple top-feeding rods to move up and down synchronously, ensuring the synchronicity of coil dropping.

[0007] Preferably, each support rod has a driven wheel at its end, the number of servo motors is the same as the number of driven wheels, and the output shaft of each servo motor has a driving wheel at its end. Both the driving and driven wheels are fitted with synchronous belts. The rotation of each support rod is controlled by a servo motor, and the rotation of each support rod is independently controlled, adaptable to different working conditions.

[0008] Preferably, there are three of each of the support rod and servo motors. The three servo motors are a first motor, a second motor, and a third motor. The first motor and the second motor are symmetrically arranged on one side wall of the support base, and the third motor is located in the middle of the first motor and the second motor, and is lower than the first motor and the second motor.

[0009] Preferably, the support rod includes an upper cover and a lower cover, with the upper cover covering the lower cover. The magnetic strip is installed inside the lower cover, and the coil placement slot is located at the bottom of the lower cover. Top-feeding holes are provided at both ends of the coil placement slot. The connection is detachable, facilitating the installation of the magnetic strip inside the support rod.

[0010] Preferably, the outer wall of the lower cover is provided with multiple slots, and the two sides of the upper cover are provided with multiple insert rods, each insert rod corresponding to one of the multiple slots. The insert rods and slots are each provided with corresponding mounting holes, and the mounting holes on the insert rods and slots are fixed together by bolts. This matching arrangement of slots and insert rods facilitates the installation of the upper and lower covers and ensures that the mounting holes on the insert rods correspond to the mounting holes on the slots.

[0011] Preferably, the inner wall of the lower cover is provided with matching guide protrusions and guide grooves between it and the magnetic strip. This provides guidance for the movement of the magnetic strip within the support rod. Attached Figure Description

[0019] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0020] See Figure 1 , Figure 2 As shown, this embodiment discloses a three-sided paint-stripping rotary fixture, including a support base 1, multiple parallel support rods 2 rotatably mounted on the support base 1, each support rod 2 having a coil placement groove 3, each support rod 2 having a hollow structure, and a magnetic strip 4 installed inside the support rod 2, the magnetic strip 4 being able to move along the thickness direction within the support rod 2, the multiple support rods 2 being driven to rotate synchronously by a servo motor 5, a lifting cylinder 6 being fixed on the support base 1, and multiple push rods 7 being provided on the telescopic shaft of the lifting cylinder 6, when the support rod 2 rotates to the point where the coil placement groove 3 faces downwards, the multiple push rods 7 can pass through the support rod 2 and push the magnetic strip 4 away from the coil placement groove 3, a collection bucket 8 being provided below the support rod 2.

[0021] like Figure 3 , Figure 4 As shown, multiple top material rods 7 are symmetrically arranged on the lifting platform 9. The middle part of the lifting platform 9 is provided with a through hole 10 corresponding to the collection bucket 8. Both ends of the lifting platform 9 are respectively connected and fixed to a lifting cylinder 6.

[0022] In this embodiment, each support rod 2 is driven by a servo motor 5. Each support rod 2 has a driven wheel 11 at its end. The number of servo motors 5 is the same as the number of driven wheels 11. The output shaft of the servo motor 5 is equipped with a driving wheel 12. Synchronous belts 13 are fitted onto the corresponding driving wheel 12 and driven wheel 11. The rotation of each support rod 2 is controlled by a servo motor 5, and the rotation of each support rod 2 is independently controlled, which can adapt to different working conditions.

[0023] In this embodiment, there are three support rods 2 and three servo motors 5. The three servo motors 5 are the first motor, the second motor and the third motor. The first motor and the second motor are symmetrically arranged on one side wall of the support base 1, and the third motor is arranged in the middle of the first motor and the second motor and is lower than the first motor and the second motor.

[0024] like Figure 5 , Figure 6 As shown, the support rod 2 includes an upper cover 2a and a lower cover 2b. The upper cover 2a is placed on the lower cover 2b, and the magnetic strip 4 is installed inside the lower cover 2b. The coil placement groove 3 is located at the bottom of the lower cover 2b, and the bottom of both ends of the coil placement groove 3 is provided with top feeding holes 14. Multiple slots 15 are provided on the outer side wall of the lower cover 2b, and multiple insertion rods 16 are provided on both sides of the upper cover 2a. Each insertion rod 16 corresponds to one of the slots 15, and mounting holes 17 are provided on the insertion rods 16 and slots 15 respectively. The mounting holes 17 on the insertion rods 16 and slots 15 are fixed together by bolts. The matching arrangement of the slots 15 and insertion rods 16 facilitates the installation of the upper cover 2a and lower cover 2b, and makes it easy for the mounting holes 17 on the insertion rods 16 to correspond to the mounting holes 17 on the slots 15. Matching guide protrusions 19 and guide grooves 20 are provided between the inner side wall of the lower cover 2b and the magnetic strip 4.

[0025] The working principle of this embodiment is as follows:

[0026] Multiple coils 18 to be stripped are conveyed into coil placement slots 3 on three support rods 2. The top of the coils 18 and the two sides to be stripped are exposed outside the coil placement slots 3. Since magnetic strips 4 are installed inside the support rods 2, the multiple coils 18 located on the coil placement slots 3 are attracted and limited by the magnetic strips 4 and do not fall out. The servo motor 5 drives the multiple support rods 2 to rotate synchronously, so that the top surface and the two sides are rotated to the bottom of a stripping machine, thereby realizing the three-sided stripping operation of the coils 18. For example, the first side of the coil 18 is stripped first. After the stripping is completed, the servo motor 5 drives the support rods 2 to rotate 90°, so that the top surface and the two sides are rotated to the bottom of a stripping machine. The top surface of coil 18 faces the paint stripper. After the top surface is stripped, the servo motor 5 drives the support rod 2 to rotate 90°, so that the second side of coil 18 faces the paint stripper. After the second side is stripped, the servo motor 5 drives the support rod 2 to rotate 90°, and the coil placement groove 3 of the support rod 2 faces downward. The lifting cylinder 6 drives the top material rod 7 to move upward. The top material rod 7 passes through the top material holes 14 at both ends of the support rod 2, and pushes the magnetic strip 4 away from the coil placement groove 3 through the guide protrusion 19 and the guide groove 20. The coil placement groove 3 loses its magnetism and no longer attracts multiple coils 18. The multiple coils 18 fall to the collection bucket 8 below by gravity for collection.

[0027] The above embodiments are only for illustrating the technical concept and features of this utility model. Their purpose is to enable those skilled in the art to understand the content of this utility model and implement it. They cannot be used to limit the protection scope of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be covered within the protection scope of this utility model.
