Description

Technical Field

[0001] This utility model relates to the technical field of capacitor production equipment, specifically to a lead wire feeding frame for capacitors. Background Technology

[0002] In the field of electronic component manufacturing, capacitors, as key components for storing charge, are widely used in various electronic devices. As the bridge connecting the capacitor and the external circuit, the quality of the capacitor leads and the stability of the lead-laying process have a crucial impact on the performance of the capacitor and the production efficiency. In order to ensure the effectiveness of capacitor lead laying, it is particularly important to develop a lead-laying frame for capacitors.

[0003] Referring to CN220131624U, a winding and unwinding take-up and rewinding frame for insulation resistance meters includes a fixed plate, a support column, and a rubber base. The fixed plate has a rolling device inside, a rotating device at its top, a take-up and unwinding reel at its top, and a lead-in device at its top. This winding and unwinding take-up and rewinding frame for insulation resistance meters, by incorporating the lead-in device, enables more neat and uniform winding and unwinding of cables, preventing cables from stacking together and causing wire damage. When cable quality issues arise, a rotating device is installed to allow the take-up and unwind reel to rotate easily, saving manpower and facilitating disassembly and replacement. The rolling device also allows the take-up and unwind reel to better handle the insulation resistance meter cable, thus increasing the take-up and unwinding speed. However, while this unwinding frame is generally well-suited for application, it is often difficult to decelerate and limit the unwinding mechanism, making it prone to excessive rotation due to inertia, which affects the unwinding effect. Further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to provide a wire feeding frame for capacitor leads, so as to solve the problem mentioned in the background art that although the wire feeding frame can be used well, it is usually not convenient to decelerate and limit the unwinding part, which makes the unwinding part prone to excessive rotation due to inertia, thus affecting the wire feeding effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lead feeding frame for capacitors, comprising a base, a cabinet fixed to one side of the top of the base, a protective cover provided on one side of the top of the cabinet, a sprocket drive mechanism inside the protective cover, the lower end of the sprocket drive mechanism extending into the interior of the cabinet and fixedly mounted with a feed roller, one end of the feed roller extending into the exterior of the cabinet and mounted with a turntable, the other end of the feed roller extending into the exterior of the cabinet and mounted with two roller discs, a reduction gear mounted on the outer wall of the cabinet below the turntable via a bracket, and a second reduction gear rotatably mounted on one side inside the reduction gear. A first reduction arm is fixed to the other side inside the reduction frame. The top end of the first reduction arm extends to the outside of the reduction frame and is rotatably mounted with a first reduction head. A stud is threadedly installed at the lower end inside the first reduction arm. One end of the stud extends to the outside of the first reduction arm and is fixedly mounted with a nut. The bottom end of the second reduction arm extends to the outside of the reduction frame and abuts against one end of the stud. The top end of the second reduction arm extends to the outside of the reduction frame and is rotatably mounted with a second reduction head. The inner wall of the second reduction head and the first reduction head contacts the outer wall of the lower end of the turntable. An electrical control box is installed on the surface of the cabinet.

[0006] Preferably, a side frame is fixedly installed on the outer wall of the cabinet on the side away from the electrical control box, and a linkage shaft is rotatably installed on the upper inner wall between the side frames. The linkage shaft is used to position the movable arm.

[0007] Preferably, one end of the linkage shaft extends to the outside of the side connecting frame and is provided with a waist-shaped hole. Two movable arms are movably installed on the outer wall of the linkage shaft at the position of the waist-shaped hole. The movable arms are slidably connected to the waist-shaped hole. The waist-shaped hole is provided to limit the range of motion of the movable arms.

[0008] Preferably, two guide wheels are rotatably mounted on the inner wall between the movable arms, and a drive arm is fixedly mounted on the outer wall of the linkage shaft inside the side connecting frame. The guide wheels are used to guide and release the lead wire.

[0009] Preferably, a telescopic cylinder is rotatably mounted on the bottom end of the drive arm. The input end of the telescopic cylinder is electrically connected to the output end of the microcontroller inside the electrical control box, and the bottom end of the telescopic cylinder is rotatably connected to the outer wall of the cabinet. The telescopic cylinder is configured to drive the linkage shaft to rotate via the drive arm.

[0010] Preferably, a motor is installed on the top of the cabinet on one side of the protective cover. The input end of the motor is electrically connected to the output end of the microcontroller inside the electrical control box. One end of the motor is connected to the upper end of the sprocket transmission mechanism. The motor is configured to drive the sprocket transmission mechanism to operate.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the wire feeding frame for capacitor leads not only ensures the wire feeding effect of capacitor leads when the wire feeding frame is used, but also improves the convenience of using the wire feeding frame, and enables the leads to enter the subsequent processing equipment in a predetermined direction, ensuring smooth wire feeding.

[0012] (1) By rotating the nut, the lower end of the drive stud located inside the first deceleration arm rotates and slides, so that one end of the stud abuts against the inner wall of the lower end of the second deceleration arm, thereby enabling the inner walls of the first deceleration head and the second deceleration head to contact the outer wall of the lower end of the turntable. When the wire feeding roller rotates and is in the wire feeding state, the wire feeding roller drives the turntable to rotate synchronously, so that the first deceleration head and the second deceleration head limit and decelerate the turntable, thereby effectively reducing the phenomenon of excessive rotation of the wire feeding roller due to inertia, thus ensuring the wire feeding effect of the capacitor lead when the wire feeding frame is used.

[0013] (2) The chain drive mechanism is driven by a motor to rotate the wire feeding roller, which can perform electric auxiliary wire feeding operation on the capacitor lead wire wound on the outer wall of the wire feeding roller, thereby improving the convenience of using the wire feeding frame.

[0014] (3) By starting the telescopic cylinder, it drives the linkage shaft to rotate through the drive arm, so that the linkage shaft drives the movable arm to rotate accordingly, thereby adjusting the tilt angle of the guide wheel. Then, by sliding the movable arm, the movable arm slides on the outer wall of the linkage shaft at the waist-shaped hole position to adjust the position of the guide wheel. Thus, the two guide wheels can guide and limit the lead wire on the outer wall of the lead wire roller to perform a lead wire feeding operation, so that the lead wire can enter the subsequent processing equipment in the predetermined direction, ensuring the smooth feeding of the lead wire.

[0024] In use, the waist-shaped hole 10 is used to limit the range of motion of the movable arm 11;

[0025] Two guide wheels 12 are rotatably mounted on the inner wall between the movable arms 11, and a drive arm 14 is fixedly mounted on the outer wall of the linkage shaft 9 inside the side connecting frame 8.

[0027] A telescopic cylinder 13 is rotatably mounted on the bottom end of the drive arm 14. The input end of the telescopic cylinder 13 is electrically connected to the output end of the microcontroller inside the electrical control box 3. The bottom end of the telescopic cylinder 13 is rotatably connected to the outer wall of the cabinet 2.

[0028] In use, the telescopic cylinder 13 is set so that the drive arm 14 drives the linkage shaft 9 to rotate.

[0029] A protective cover 5 is provided on one side of the top of the cabinet 2. A motor 4 is installed on the top of the cabinet 2 on one side of the protective cover 5. The input end of the motor 4 is electrically connected to the output end of the microcontroller inside the electrical control box 3. One end of the motor 4 is connected to the upper end of the sprocket transmission mechanism 16.

[0030] In use, the motor 4 is configured to drive the sprocket transmission mechanism 16 to operate;

[0031] The protective cover 5 is equipped with a sprocket drive mechanism 16. The lower end of the sprocket drive mechanism 16 extends into the interior of the cabinet 2 and is fixedly installed with a wire feeding roller 6. One end of the wire feeding roller 6 extends into the exterior of the cabinet 2 and is installed with a turntable 15. The other end of the wire feeding roller 6 extends into the exterior of the cabinet 2 and is installed with two roller discs 7. A reduction gear 17 is mounted on the outer wall of the cabinet 2 below the turntable 15 via a bracket. A second reduction arm 22 is rotatably mounted on one side inside the reduction gear 17, and a first reduction arm 19 is fixed on the other side inside the reduction gear 17. The top end of the first reduction arm 19 extends into the reduction gear. The first reduction head 20 is rotatably mounted on the outside of the first reduction arm 19. A stud 21 is threaded on the lower end of the first reduction arm 19. One end of the stud 21 extends to the outside of the first reduction arm 19 and is fixedly mounted with a nut 18. The bottom end of the second reduction arm 22 extends to the outside of the reduction frame 17 and abuts against one end of the stud 21.

[0032] In this embodiment, the capacitor lead wire is first wound and placed on the outer wall of the pay-off roller 6 by two roller discs 7. Then, the motor 4 drives the sprocket transmission mechanism 16 to rotate the pay-off roller 6, thus performing an electric auxiliary pay-off operation on the capacitor lead wire wound on the outer wall of the pay-off roller 6. Afterward, the telescopic cylinder 13 is activated, which drives the linkage shaft 9 to rotate via the drive arm 14. This causes the linkage shaft 9 to drive the movable arm 11 to rotate accordingly, thereby adjusting the tilt angle of the guide wheel 12. Then, by sliding the movable arm 11, the movable arm 11 slides on the outer wall of the linkage shaft 9 at the position of the waist-shaped hole 10 to adjust the position of the guide wheel 12. The two guide wheels 12 guide and limit the wire feeding operation on the outer wall of the wire feeding roller 6. Finally, by rotating the nut 18, the lower end of the drive stud 21 located inside the first deceleration arm 19 is rotated and slid, so that one end of the stud 21 abuts against the inner wall of the lower end of the second deceleration arm 22. This allows the inner walls of the first deceleration head 20 and the second deceleration head 23 to contact the outer wall of the lower end of the turntable 15. When the wire feeding roller 6 rotates and is in the wire feeding state, the wire feeding roller 6 drives the turntable 15 to rotate synchronously. The first deceleration head 20 and the second deceleration head 23 limit and decelerate the turntable 15, thereby effectively reducing the phenomenon of excessive rotation of the wire feeding roller 6 due to inertia, thus completing the use of the wire feeding frame.
