Description

Technical Field

[0001] This utility model relates to the field of sensor pin cutting equipment technology, and in particular to an integrated tooling for sensor pin cutting and bending. Background Technology

[0002] Traditional material shaping involves cutting the leads of through-hole components, which uses machines or fixtures. However, these devices only control the lead length and do not perform shaping. Shaping is done manually, resulting in poor consistency and making it unsuitable for machine placement.

[0003] To address this, the present invention provides an integrated tooling for cutting and bending sensor pins to ensure consistency in the cutting and shaping of sensor pins. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing an integrated tooling for sensor shearing and bending.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sensor pin bending and shearing integrated fixture includes a base, on which a support platform for placing pins is fastened. A cutting tool is vertically slidably mounted on the base directly above the support platform. The cutting tool is driven by a drive assembly and can move vertically back and forth. A limit plate is connected to the side wall of the support platform along its length direction via a spring. A push plate is vertically slidably mounted on the base at the edge of the limit plate opposite to the support platform. The push plate is driven by a drive assembly and can move horizontally back and forth. A pin punch plate is vertically slidably mounted on the base at the edge of the support platform opposite to the limit plate. A spring is provided between the pin punch plate and the base. A top rod that cooperates with the side of the cutting tool is provided at the upper end of the pin punch plate.

[0007] Preferably, the cutting tool includes a top plate, a bottom plate, and a gate; the top plate is connected to the output end of the drive assembly, and multiple columns are evenly distributed between the top plate and the bottom plate to separate the bottom plate from the top plate; the gate is located at the lower end of the bottom plate.

[0008] Preferably, the top plate has a through hole at its center, into which a stud is inserted. The stud has self-locking nuts screwed onto both the upper and lower ends of the top plate, which abut against the top plate. The stud is connected to the output end of the drive assembly.

[0009] Preferably, the bottom plate is smaller than the top plate, and sleeves are fastened to both ends of the top plate. A guide post through the sleeve is fixed on the base.

[0010] Preferably, friction damping is provided between the sleeve and the guide post.

[0011] Preferably, the drive component one and drive component two have the same structure. Drive component one is set on the bracket located on the side of the lifting platform away from the limiting plate, and drive component two is set on the edge of the base.

[0012] The drive assembly includes a guide sleeve fixed on the bracket, a lifting shaft inserted inside the guide sleeve, a cutting tool located at the lower end of the lifting shaft, and an L-shaped handle rotatably mounted on the bracket above the lifting shaft. Two C-shaped connectors are symmetrically rotatably connected to the upper end of the lifting shaft, and the upper ends of the two connectors are rotatably connected to the bend of the handle.

[0013] Preferably, a positioning plate is symmetrically provided on the base on the side of the limiting plate opposite to the lifting platform.

[0014] Preferably, the two positioning plates can be horizontally displaced along the vertical direction of the center line of the support platform.

[0015] Compared with the prior art, this utility model provides an integrated tooling for sensor lead shearing and bending, which has the following advantages:

[0016] 1. During use, the cutting blade descends to cut the pins, and the pins are cut synchronously to ensure consistent cutting length. After cutting, the cutting blade rises, the push plate extends forward and moves against the circuit board until it hits the pin punch plate, so that the cut pin ends are shaped against the pin punch plate, achieving consistent shaping.

[0017] 2. During the descent of the cutting blade, before the cutting blade contacts the lead, the push rod will first contact the cutting blade and descend below the support platform against the lead punch plate. This prevents the lead from being lifted and deformed by the lead punch plate during the cutting process, which would result in inconsistent cutting positions.

[0018] Other advantages, objectives and features of this invention will be set forth in part in the description which follows; and in part will be apparent to those skilled in the art upon examination of the following description; or may be taught from practice of this invention.

[0028] The following will refer to the appendix in the embodiments of this utility model. Figure 1-8 The technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments.

[0029] Example 1: To address the problems existing in the prior art, this example provides a sensor lead shearing and bending integrated fixture, including a base 1. A support platform 14 for placing leads is fastened on the base 1. A cutting blade 3 is vertically slidably mounted on the base 1 directly above the support platform 14. The cutting blade 3 is driven by a drive assembly 4 and can move vertically back and forth. A limiting plate 9 is connected to the side wall of the support platform 14 along its length direction via a spring. A push plate 7 is vertically slidably mounted on the base 1 at the edge of the limiting plate 9 away from the support platform 14. The push plate 7 is driven by a drive assembly 8 and can move horizontally back and forth. A lead punch plate 10 is vertically slidably mounted on the base 1 at the edge of the support platform 14 away from the limiting plate 9. A spring 2 is provided between the lead punch plate 10 and the base 1. A top rod 11 that cooperates with the side of the cutting blade 3 is provided at the upper end of the lead punch plate 10.

[0030] In this embodiment, when the pin punch plate 10 is not under force, the spring 2 extends and contracts normally, and the upper end face of the pin punch plate 10 extends out of the upper end face of the support platform 14 with a height not exceeding 1 cm.

[0031] According to the above plan:

[0032] In use, the sensor circuit board is placed on the platform of base 1 and pushed until it abuts against the limiting plate 9. At this time, the sensor pins rest on the lifting platform 14. The cutting blade 3 is driven down by the drive component 4 to cut the pins. The pins are cut synchronously to ensure consistent cutting length. During the descent of the cutting blade 3, before the cutting blade 3 contacts the pin, the push rod 11 will first contact the cutting blade 3 and abut against the pin punch plate 10 as it descends below the lifting platform 14, compressing the spring 2. This prevents the pins from being pushed up and deformed by the pin punch plate 10 during the cutting process, which would result in inconsistent cutting positions.

[0033] After cutting, the cutting blade 3 rises, and the pin punch plate 10 returns to its original position under the action of spring 2, thus removing the cut pin. Then, the push plate 7 is driven forward by the drive assembly 2 8, moving forward against the circuit board until it rests against the pin punch plate 10. This allows the cut pin ends to be shaped against the pin punch plate 10, achieving consistent shaping. Afterward, the push plate 7 returns to its original position, allowing the circuit board to be removed, preparing for the next circuit board pin cutting operation.

[0034] In this embodiment, the circuit board is pushed forward, the limiting plate 9 is pushed forward by the circuit board, and the spring is compressed; after the push plate 7 is reset, the limiting plate 9 is pushed back to its original position by the spring. When the limiting plate 9 and the spring are configured, the impact shaping of the circuit board pins is shaped to flow out of the forward movement space, and the position of the circuit board is kept consistent when it is placed on the base 1, so as to ensure the consistency of the pin cutting length.

[0035] Example 2, a further embodiment of this solution, provides a specific structure for a cutting tool 3: the cutting tool 3 includes a top plate 301, a bottom plate 302, and a gate 303; the top plate 301 is connected to the output end of the drive assembly 4, and multiple columns are evenly distributed between the top plate 301 and the bottom plate 302 so that the bottom plate 302 and the top plate 301 are separated; the gate 303 is located at the lower end of the bottom plate 302.

[0036] In a further embodiment of this solution (Example 3), the top plate 301 has a through hole at its center, into which a stud 304 is inserted. Self-locking nuts 305 are screwed onto both the upper and lower ends of the stud 304, abutting against the top plate 301. The stud 304 is connected to the output end of the drive assembly 4. By adjusting the positions of the two sets of self-locking nuts 305, the position of the top plate 301 on the stud 304 can be adjusted, thereby adjusting the distance between the gate 303 and the base 1 platform to accommodate the pin cutting of sensors with different thicknesses.

[0037] In this example, the support platform 14 is fastened to the base 1 by bolts. After the position of the cutting tool 3 on the stud 304 changes, in order to ensure that the circuit board pins can be attached to the support platform 14, a shim can be added under the support platform 14.

[0038] In a further embodiment of this solution, as described in Example 4, the bottom plate 302 is smaller than the top plate 301. Sleeves 5 are securely mounted at both ends of the top plate 301, and guide posts 6 penetrating the sleeves 5 are fixed on the base 1. The cooperation between the sleeves 5 and the guide posts 6 guides the vertical movement of both ends of the cutting tool 3, increasing the consistency and stability of the overall vertical movement of the cutting tool 3.

[0039] In Example 5, a further embodiment of this solution, friction damping is provided between the sleeve 5 and the guide post 6. Increasing the frictional resistance between the sleeve 5 and the guide post 6 increases the resistance to the lifting and lowering of the cutting blade 3, preventing the cutting blade 3 from easily lifting and lowering, thus improving safety during use.

[0040] In a further embodiment of this solution, in Example 6, the drive component 4 and drive component 8 have the same structure. The drive component 4 is mounted on the bracket 2 located on the side of the lifting platform 14 away from the limiting plate 9, and the drive component 8 is mounted on the edge of the base 1.

[0041] The drive assembly 4 includes a guide sleeve 401 fixed on the bracket 2, a lifting shaft 402 inserted into the guide sleeve 401, and a cutting tool 3 disposed at the lower end of the lifting shaft 402. An L-shaped handle 404 is rotatably mounted on the bracket 2 above the lifting shaft 402. Two C-shaped connectors 403 are symmetrically rotatably connected to the upper end of the lifting shaft 402, and the upper ends of the two connectors 403 are rotatably connected to the bend of the handle 404.

[0042] The drive assembly 8 includes a guide sleeve 2 fixed on the axis of the base 1, a movable shaft 801 inserted inside the guide sleeve 2, and a push plate 7 disposed at the end of the movable shaft 801 facing the limiting plate 9. Two C-shaped connectors 802 are symmetrically rotatably connected to the end of the movable shaft 801 away from the limiting shaft. An L-shaped handle 803 is rotatably mounted on the side of the base 1, and the other ends of the two connectors 802 are rotatably connected to the bend of the handle 803.

[0043] When the cutting cutter 3 is driven to rise: hold the handle 404 and turn it clockwise. The handle 404 rotates clockwise and drives the lifting shaft 402 to rise through the two connecting parts 403. The lifting shaft 402 drives the cutting cutter 3 to rise, thereby realizing the return of the cutting station.

[0044] When the cutting tool 3 is driven to descend: hold the handle 404 and turn it counterclockwise. The handle 404 deflects counterclockwise and drives the lifting shaft 402 to descend through the two connecting parts 802. The lifting shaft 402 drives the cutting tool 3 to descend, realizing the feed of the cutting station.

[0045] The process of driving the push plate 7 to move is similar to that described above.

[0046] In a further embodiment of this solution, as described in Example 7, positioning plates 12 are symmetrically arranged on the base 1 on the side of the limiting plate 9 opposite to the lifting platform 14. The two sets of positioning plates 12 are snapped into both sides of the circuit board, increasing the stability of the circuit board placement and preventing differences in pin cutting lengths caused by lateral deviation during circuit board placement.

[0047] In Example 8, a further embodiment of this solution, the two positioning plates 12 can be horizontally displaced along the vertical direction of the center line of the lifting platform 14.

[0048] See attached document Figure 1 and attached Figure 7 As shown, multiple rows of threaded holes 13 are provided on both sides of the base 1 platform. The positioning plate 12 is provided with mounting holes that correspond one-to-one with a row of threaded holes 13. By connecting the mounting holes and the threaded holes 13 with screws, the positioning plate 12 and the base 1 can be detachably connected. By installing different rows of threaded holes 13, the position of the positioning plate 12 can be adjusted to adapt to the cutting of circuit board pins of different widths.

[0049] In this embodiment, the lengths of the top plate 301 and the limiting plate 9 are less than the minimum distance between the two positioning plates 12, in order to prevent collision interference caused by the displacement of the positioning plates 12.

[0050] In this design, the bracket 2 includes two mounting columns with grooves on them. A slider is slidably mounted within each groove, and a mounting plate is securely fastened between the two sliders. The drive assembly 4 is mounted on the mounting plate. The sliders are driven by a cylinder to rise and fall. An electronic grid is located on the side of the mounting columns. When a hand is placed directly below the cutting blade 3, the grid is blocked, sending a signal to the cylinder controller. The cylinder then activates, driving the sliders to rise. The sliders then lift the mounting plate, thereby lifting the cutting blade 3 by at least 5 cm. This ensures that even when the cutting blade 3 is driven down by the drive assembly 4, it will not cut the user's hand, improving safety.
