Abstract
Description
Technical Field
[0001] This application relates to the field of jigs, and more particularly to a lead wire bending jig. Background Technology
[0002] In the field of laser packaging bases, lasers are gradually trending towards higher power and a greater number of chips being mounted, leading to a trend towards larger base dimensions. However, the mounting space within laser modules is limited, necessitating the modification of exposed leads from straight sections to curved right angles to reduce space requirements. In the lead bending process, the rationality of the lead bending fixture is crucial to ensuring that the bent leads are at right angles and meet the base assembly requirements.
[0003] Currently, lead wire bending fixtures typically consist of a base, a rotor, and a positioning block. The lead wire to be bent is placed in the notch of the positioning block, and the rotor is rotated. The rotor then abuts against the lead wire to perform the bending. However, during the bending process, after the lead wire is subjected to the abutting force of the rotor, the end of the lead wire away from the rotor is prone to swinging, resulting in a bending angle greater than 90° and forming an angle beyond the required range. This presents a problem of difficulty in controlling the bending angle of the lead wire within the required range. Utility Model Content
[0004] To improve the accuracy of the bending angle of the lead wire when bending it, this application provides a lead wire bending fixture.
[0005] The lead wire bending fixture provided in this application adopts the following technical solution:
[0006] A lead wire bending fixture includes a base, a rotor, a positioning block, and a limiting member. The rotor is rotatably mounted on the base, the positioning block is mounted on the base, the positioning block has a through hole for inserting the lead wire, the rotor has a protrusion for abutting against the lead wire, and the limiting member is mounted on the base and is used to position the end of the lead wire away from the protrusion.
[0007] By adopting the above technical solution, the worker inserts the lead wire to be bent into the through hole, and uses the limiting component to position the end of the lead wire away from the protrusion. Then, the rotor is rotated, and the rotor drives the protrusion to abut against the lead wire, causing the lead wire to bend. When the protrusion abuts the lead wire against the positioning block, the lead wire can be bent at 90°. During the bending process, the limiting component positions the lead wire, improving the stability of the lead wire during the bending process, and thus improving the accuracy of the bending angle of the lead wire when bending it.
[0008] Optionally, the limiting component includes a limiting block, which is disposed on the base and has a limiting groove for the end of the lead wire away from the protrusion to be engaged.
[0009] By adopting the above technical solution, when placing the lead wire, the end of the lead wire away from the protrusion is inserted into the limiting groove, and the side wall of the limiting groove can position the lead wire, reducing the possibility of the lead wire swinging away from the bending end during the bending process.
[0010] Optionally, the positioning block can be detachably mounted on the base.
[0011] By adopting the above technical solution, after the positioning block is removed from the base, positioning blocks with different through hole widths can be installed on the base, thereby adapting to lead wires of different diameters.
[0012] Optionally, the rotor is provided with a stop block, which is used to abut against the base when the rotor rotates 90°.
[0013] By adopting the above technical solution, when the rotor rotates 90° and drives the lead wire to bend 90°, the stop block abuts against the base to limit the rotation of the rotor and reduce the possibility of the rotor rotating too much and squeezing the lead wire onto the positioning block and causing damage.
[0014] Optionally, the rotor is provided with a handle.
[0015] By adopting the above technical solution, staff can easily and effortlessly drive the rotor to rotate by turning the handle.
[0016] Optionally, the base has a groove, and the limiting block is provided with an insert for being embedded in the groove.
[0017] By adopting the above technical solution, the movable limiting block allows the insert to be embedded in the groove, thus making it convenient and quick to position and install the limiting block on the base.
[0018] Optionally, the limiting block is slidably mounted on the base, and the base is provided with a control component for driving the limiting block to slide.
[0019] By adopting the above technical solution, the staff can drive the limiting block to slide on the base through the control component, and adjust the distance between the limiting block and the through hole. This allows them to adjust the length of the lead wire extending out of the through hole after it is inserted into the limiting groove, and thus adjust the bending point of the lead wire.
[0020] Optionally, the control component includes a control screw, which is rotatably mounted on the base and threadedly connected to the limit block.
[0021] By adopting the above technical solution, the operator can turn the control screw to drive the limit block to slide and adjust the distance between the limit block and the through hole.
[0022] In summary, this application includes at least one of the following beneficial technical effects:
[0023] 1. During the bending process, the limiting component positions the lead wire, improving the stability of the lead wire during bending and thus improving the accuracy of the bending angle of the lead wire when bending it;
[0024] 2. When the rotor rotates 90° and drives the lead wire to bend 90°, the stop block abuts against the base to limit the rotation of the rotor and reduce the possibility of the lead wire being squeezed and damaged by excessive rotor rotation.
[0025] 3. The control component drives the limit block to slide on the base. Adjusting the distance between the limit block and the through hole allows for adjustment of the length of the lead wire extending out of the through hole after it is inserted into the limit groove, thereby adjusting the bending point of the lead wire.

[0031] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.
[0032] Example 1
[0033] This application discloses a lead wire bending fixture.
[0034] Reference Figure 1 The lead wire bending fixture includes a base 1, a rotor 2, a positioning block 3, and a limiting component 4. The rotor 2 is rotatably mounted on the base 1. A handle 7 is installed on the rotor 2. The handle 7 provides a gripping part for the operator to drive the rotor 2 to rotate, increasing the lever arm for driving the rotor 2 to rotate, making it easier and more labor-saving for the operator to rotate the rotor 2.
[0035] Reference Figure 1The positioning block 3 is detachably mounted on the base 1. In this embodiment, the positioning block 3 is detachably mounted on the base 1 by bolts. In other embodiments, the positioning block 3 can also be detachably mounted on the base 1 by installing a spring pin on the base 1 and inserting the spring pin into the positioning block 3. The positioning block 3 has a through hole 31 at one end facing the rotor 2. The through hole 31 is used for inserting the lead wire. The width of the opening of the through hole 31 is adapted to the diameter of the lead wire.
[0036] By unscrewing the bolts, the positioning block 3 can be removed from the base 1. Then, the positioning block 3 with a different opening width of the through hole 31 can be replaced. The replacement positioning block 3 can then be positioned and installed on the base 1 by bolts, thereby realizing the replacement of the positioning block 3 with a different opening width of the through hole 31 to meet the applicability when bending leads of different diameters.
[0037] Reference Figure 1 , Figure 2 , Figure 3 The rotor 2 is equipped with a protrusion 5. When the rotor 2 rotates to the starting position, the side of the protrusion 5 near the lead wire is flush with the sidewall of the opening of the through hole 31 away from the rotating side of the rotor 2. The limiting member 4 is installed on the base 1. The limiting member 4 is used to position the end of the lead wire away from the protrusion 5. The limiting member 4 includes a limiting block 41. The base 1 is provided with a groove 11. The limiting block 41 is equipped with an insert 8. The insert 8 is used to be embedded in the groove 11. The operator moves the limiting block 41 so that the insert 8 on the limiting block 41 is embedded in the groove 11. The sidewall of the groove 11 restricts the insert 8, improving the stability of the limiting block 41 on the base 1, so that the installation of the limiting block 41 on the base 1 can be achieved conveniently and quickly. The side of the limiting block 41 facing the through hole 31 is provided with a limiting groove 411 that communicates with the through hole 31. The opening cross-sectional shape and size of the limiting groove 411 are the same as the cross-sectional shape and size of the end of the lead wire away from the protrusion 5.
[0038] Reference Figure 1 , Figure 2 A stop block 6 is installed on the rotor 2. The stop block 6 is used to abut against the base 1 when the rotor 2 rotates 90° and causes the lead wire to bend 90°. When the operator drives the rotor 2 to rotate 90° so that the protrusion 5 on the rotor 2 abuts against the lead wire and bends 90°, the rotor 2 drives the protrusion 5 to rotate, and the protrusion 5 abuts against the base 1, which limits the continued rotation of the rotor 2 and reduces the possibility that the rotor 2 will rotate too much and continue to squeeze the lead wire against the positioning block 3, resulting in damage to the lead wire.
[0039] The implementation principle of Embodiment 1 of this application is as follows: The operator inserts the lead wire to be bent into the through hole 31 and drives the end of the lead wire away from the rotor 2 to be inserted into the limiting groove 411. The side wall of the limiting groove 411 positions the end of the lead wire away from the protrusion 5, and the side wall of the through hole 31 positions the lead wire. Subsequently, the operator holds the handle 7 to drive the rotor 2 to rotate. The rotor 2 drives the protrusion 5 to rotate, and the protrusion 5 can then abut against the section of the lead wire extending out of the through hole 31 for bending. When the section of the lead wire extending out of the through hole 31 is bent by the protrusion 5 until it abuts against the positioning block 3, the 90° bend of the lead wire is completed. During the bending process of the lead wire, the limiting groove 411 positions the end of the lead wire away from the protrusion 5, reducing the possibility of swinging at the end away from the bend during the bending process, improving the stability of the lead wire during the bending process, and thus improving the accuracy of the bending angle of the lead wire.
[0040] Example 2
[0041] Reference Figure 4 The difference between this embodiment and Embodiment 1 is that the limiting block 41 is slidably mounted on the base 1 in the direction toward the through hole 31, and a control component 9 is mounted on the base 1. The control component 9 is used to drive the limiting block 41 to slide. The control component 9 includes a control screw 91, which is rotatably mounted on the base 1. The control screw 91 passes through the positioning block 3 and is threadedly connected to the limiting block 41.
[0042] The implementation principle of Embodiment 2 of this application is as follows: The operator places the limiting block 41 on the base 1, passes the control screw 91 through the base 1 and through the positioning block 3, and then the control screw 91 is threaded into the limiting block 41, thus completing the installation of the limiting block 41 on the base 1. Subsequently, the operator turns the control screw 91 to drive the limiting block 41 to slide on the base 1, adjust the distance between the limiting block 41 and the through hole 31, and thus adjust the length of the lead wire extending out of the through hole 31 after the lead wire is inserted into the limiting groove 411, and adjust the bending point of the lead wire to meet the applicability of bending at different lengths of the lead wire.
[0043] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
