DETAILED DESCRIPTION

[0025] This embodiment is a capacitor lead wire reinforcement device, such as Figure 1As shown, it includes an upper roller 1 and a lower roller 2 corresponding to each other, and a rolling groove 102 for the lead wire to pass through is provided between the upper roller 1 and the lower roller 2. The size of the rolling groove 102 can be adjusted according to the size of the lead wire. An inlet guide 3 is provided on one side of the upper roller 1 and the lower roller 2, and an outlet guide 4 is provided on the other side of the upper roller 1 and the lower roller 2. The inlet guide 3 can correctly guide the lead wire into the rolling groove 102, and the outlet guide 4 can smoothly lead the lead wire out of the rolling groove 102. The working surface sizes of the inlet guide 3 and the outlet guide 4 are adapted to the lead wire, and can straighten the lead wire to enter and lead out smoothly, and the surfaces of the two have a certain degree of finish to prevent the surface of the lead wire from being scratched.

[0026] Specific, combined Figure 2 The inlet guide 3 includes a bottom plate 5, and a guide plate 6 and a guide group are provided on the upper end surface of the bottom plate 5. The guide group is correspondingly arranged at the discharge end of the guide plate 6 and the feed end of the rolling groove 102. A heating wire 7 is laid on the inner surface of the guide plate 6. The lead wire will bend because it is subjected to tensile stress and compressive stress, and the two forces have different magnitudes. Therefore, the lead wire is placed in a high temperature environment to eliminate the stress inside the lead wire. The lead wire is repeatedly bent by changing the rolling angle of the upper roller 1 and the lower roller 2 to change the straightness of the lead wire, thereby achieving the purpose of straightening and improving the applicability of the lead wire.

[0027] The guide group includes a guide roller 1 8 and a guide roller 2 9 symmetrically arranged on both sides of the outlet end of the guide plate 6, the roller surfaces of the guide roller 1 8 and the guide roller 2 9 face each other, and the guide roller 1 8 and the guide roller 2 9 are both slidingly corresponding to the bottom plate 5; the guide roller 1 8 is axially connected to a gear 12 through a guide rod 10, and the guide roller 2 9 is axially connected to a gear 2 13 through a guide rod 2 11. The guide roller 1 8 is rotatably connected to the guide rod 10, and the guide roller 2 9 is rotatably connected to the guide rod 2 11. The gear Gear 1 12 and gear 2 13 are meshed with each other, and the centers of gear 12 and gear 2 13 are connected to a positioning plate 14 through a rotating shaft. A bracket can be installed on the upper end surface of the bottom plate 5, and the positioning plate 14 is assembled on the bracket to position the guide group. The wheel surfaces of gear 12 and gear 2 13 are fixedly connected to guide rod 1 10 and guide rod 2 11 respectively. The activities of guide rod 1 10 and guide rod 2 11 can respectively drive gear 12 and gear 2 13 to rotate around the positioning plate 14.

[0028] A spring column 17 and a support rod 15 are connected between the guide rod 10 and the guide rod 2 11. Positioning seats 16 are provided on the guide rod 10 and the side walls of the guide rod 2 11. The support rod 15 passes through the two positioning seats 16 and is movably connected relative to the positioning seats 16. The spring column 17 and the support rod 15 can increase the guiding properties of the activities of the guide rod 10 and the guide rod 2 11. When the guide rod 10 and the guide rod 2 11 move, the support rod 15 can generate corresponding activity adjustments in the positioning seat 16 to avoid relative deviation between the guide roller 1 8 and the guide roller 2 9.

[0029] After being heated by the guide plate 6, the lead wire enters between the guide roller 1 8 and the guide roller 2 9, and the motor drives the gear 12 and the gear 2 13 to mesh and rotate to drive the guide rod 10 and the guide rod 2 11 so that the guide roller 1 8 and the guide roller 2 9 are spaced at a distance suitable for the lead wire. When the lead wires of different sizes pass through the guide roller 1 8 and the guide roller 2 9, the guide roller 1 8 and the guide roller 2 9 are spread at different distances. At the same time, the meshing of the gear 12 and the gear 2 13 can position the guide rod 10 and the guide rod 2 11. When the lead wire passes through the guide roller 1 8 and the guide roller 2 9, the guide roller 1 8 and the guide roller 2 9 are driven to rotate. The rotation of the guide roller 1 8 and the guide roller 2 9 directs the lead wire into the rolling groove 102, thereby avoiding the lead wire from rotating at a large angle when entering the rolling groove 102, and also allowing the lead wire to enter the rolling groove under the guidance of the guide roller 1 8 and the guide roller 2 9.

[0030] Combination Figure 3 The outlet guide 4 includes a base 18, and the upper end surface of the base 18 is provided with two receiving seats 19 corresponding to the rolling groove 102. The receiving seat 19 is provided with a groove 20 arranged along the lead line leading direction. One of the two receiving seats 19 is located at the outlet end of the rolling groove 102, and the other is located at the end away from the outlet end of the rolling groove 102. A lower pressing wheel 21 is arranged in the groove 20. The upper end surface of the receiving seat 19 is connected to an upper pressing wheel 22 symmetrically corresponding to the lower pressing wheel 21 through a movable seat 23. The upper pressing wheel 22 and the lower pressing wheel 21 correspond to each other up and down. The movable seat 23 is connected to the receiving seat 19 through a telescopic rod 24. The lead line enters the receiving seat after being led out of the rolling groove 102. 19, with the continuous output of the rear end of the lead line, the front end of the lead line enters the lower pressing wheel 21, and the downward pressing distance of the upper pressing wheel 22 is adjusted by the telescopic rod 24 according to the size of the lead line, so that the lead line is between the wheel surfaces of the upper pressing wheel 22 and the lower pressing wheel 21. The wheel surface curvatures of the upper pressing wheel 22 and the lower pressing wheel 21 can be adapted according to the curvature of the lead line to maintain the strength of the lead line. The motor drives the upper pressing wheel 22 and the lower pressing wheel 21 to rotate, gradually pulling the entire lead line away from the rolling groove 102. At the same time, the upper pressing wheel 22 and the lower pressing wheel 21 can maintain the straightness of the lead line and position the lead line output direction to avoid large-angle rotation of the lead line leading out of the rolling groove 102.

[0031] The upper end surface of the base 18 is also provided with a guide rail 25 located between the two receiving seats 19, and the guide rail 25 is connected to a lead-out piece that moves between the two receiving seats 19. Specifically, the lead-out piece includes a base plate 27 and a base 28 arranged above the base plate 27. The base plate 27 is connected to the guide rail 25 through a slider 26. The position of the entire lead-out piece can be adjusted by sliding the slider 26 on the guide rail 25. The upper end surface of the base 28 is connected to a guide seat 29 that is movably connected to the base 28. One end of the guide seat 29 A pressure plate 31 movably connected to the guide seat 29 is connected via a connecting rod 30. The guide seat 29 is located on the upper end surface of the base 28, and the pressure plate 31 is located at the front end of the base. There is a height difference between the guide seat 29 and the pressure plate 31, so the connecting rod 30 is in an inclined state between the guide seat 29 and the pressure plate 31. The other end of the guide seat 29 is connected to a driving shaft 32 that drives the guide seat 29 to move on the base 28. A limiting groove 34 is provided on the base 28. The guide seat 29 is movably connected to the limiting groove 34 through a matching column 33 toward the bottom of the base 28.

[0032] The drive shaft 31 is driven by the motor to drive the guide seat 29 to produce a linear displacement along the upper end surface of the base 28. The guide seat 29 produces a linear displacement of a controllable distance under the cooperation and limitation of the matching column 33 and the limit groove 34. When the drive shaft 31 is extended, the guide seat 29 moves forward in front of the upper end surface of the base 28, so that the pressure plate 31 is displaced away from the base 28. The pressure plate 31 is pressed downward under the action of gravity, and at the same time, it is pressed downward for a limited distance under the traction of the connecting rod 30 until the bottom end surface of the pressure plate 31 is crimped onto the lead bar, so that the lead bar is positioned between the pressure plate 31 and the substrate 27. The substrate 27 slides along the guide rail 26 through the slider 25, and moves the lead-out member crimped with the lead bar to another receiving seat 19, so that the lead bar is moved out.

[0033] The lead wires which are guided by the upper pressing wheel 22 and the lower pressing wheel 21 are gradually moved between the pressure plate 31 and the base plate 27 during the rotation of the upper pressing wheel 22 and the lower pressing wheel 21. The lead-out piece transfers the smoothly led-out lead wires to the receiving seat 19 away from the rolling groove 102. During the lead-in, lead-out and transfer process, the directional movement of the lead wires is always maintained to prevent the lead wires from rotating at large angles, thereby increasing the strength of the lead wires, preventing the lead wires from being deformed, and facilitating the batch removal of the lead wires.

[0034] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
