Description

Technical Field

[0001] This utility model belongs to the field of core wire shaping, and in particular relates to a core wire shaping mechanism. Background Technology

[0002] Soldering the wires to the PCB (Printed Circuit Board) is a critical process. After the wires have been sheathed, the exposed core wires need to be soldered to the PCB pads. However, the pin pitch of the core wires often does not match the pin pitch of the pads. Therefore, the core wires must be shaped to match the pin pitch of the pads to ensure soldering accuracy and connection reliability.

[0003] Currently, the industry commonly uses manual shaping blades to shape the core wires. In practice, workers must manually place the wires into the shaping blades one by one, performing the shaping action manually. This traditional method has significant drawbacks:

[0004] High labor intensity: Manually placing the wires one by one and operating the shaping blades requires a lot of manpower, especially in mass production, the operation is cumbersome and inefficient.

[0005] Poor uniformity and consistency: The shaping effect depends on human experience. Differences in the techniques of different operators can easily lead to unstable pin distance accuracy after core wire shaping, making it difficult to meet the requirements of high-precision products.

[0006] Limited operability: For complex products with high pin spacing accuracy requirements and a large number of core wires, the limitations of manual shaping are more prominent. It cannot meet the needs of automated production and it is difficult to guarantee the quality consistency of mass production. Utility Model Content

This greatly improves the uniformity and consistency of core wire shaping, making it particularly suitable for mass production of high-precision products and greatly improving shaping efficiency.

[0021] 2. The wire channel combined with the first straight module achieves the enclosure and straightening effect of the wire groove. Furthermore, the first and second wire grooves are processed separately, which can effectively control the surface polishing during processing. This avoids the problem of insufficient polishing inside the wire groove caused by integrated processing, which leads to wire scratches. This ensures the integrity and surface quality of the wire and provides a high-quality material foundation for subsequent production.

[0022] 3. The height of the adjustable limiting component is adjusted by the cooperation of the first bolt and the third spring, and fixed by the second bolt to accurately compensate for processing and assembly errors.

[0023] 4. The core wire is pushed down into the groove by the insertion plate. Combined with the shaping teeth and its bevel, the spacing of the core wire can be adjusted and shaped to complete the pin separation operation.

[0024] 5. By assembling and disassembling the mounting bracket and the base, the mounting bracket and its upper structure can be used as a module. The module is precisely positioned by positioning pins and positioning bushings. The module is assembled offline, and only the upper and lower modules need to be disassembled and assembled when changing models, so as to achieve quick model change.

[0025] 6. By using the third bolt and the fourth spring in combination, the deviation in the accuracy of the dividing line caused by machining errors can be compensated by adjusting left and right.

[0026] 7. By using the slot and the block to position the first and second shaping blades before the insert plate is inserted into the groove, the precise fit between the insert plate and the shaping teeth is ensured. Attached Figure Description

Detailed Implementation

[0040] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0041] Contents not described in detail in this specification are existing technologies known to those skilled in the art. In the description of this utility model, it should be understood that terms such as "center," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," and "counterclockwise," indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are used only for the convenience of describing this utility model and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as limiting this utility model. Furthermore, terms such as "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] like Figures 1 to 12As shown, this embodiment provides a core wire shaping mechanism, including a first linear module 1, a second linear module 2, an upper shaping group 3, a lower shaping group 4, an upper guide plate 5, and a lower guide plate 6. The second linear module 2 is fixed to the movable end of the first linear module 1. The second linear module 2 has two movable ends. The upper shaping group 3 and the lower shaping group 4 are respectively fixed to the two movable ends of the second linear module 2. The upper shaping group 3 is located above the lower shaping group 4. The upper shaping group 3 is provided with the upper guide plate 5, which can move up and down relative to the upper shaping group 3. In the initial state, the bottom end of the upper guide plate 5 is located below the shaping end of the upper shaping group 3. The lower shaping group 4 is provided with the lower guide plate 6, which can move up and down relative to the lower shaping group 4. In the initial state, the top end of the lower guide plate 6 is located above the shaping end of the lower shaping group 4. In this embodiment, the first linear module 1 is a Y-axis linear module, and the second linear module 2 is a Z-axis linear module. The first linear module 1 drives the second linear module 2 and its upper structure to the fixed position. Then, the second linear module 2 drives the lower shaping group 4 to move upward, causing the lower guide plate 6 to move upward until it horizontally supports the wire. Next, the second linear module 2 drives the upper shaping group 3 to move downward, causing the upper guide plate 5 to move downward until the lower guide plate 6 contacts the upper guide plate 5. At this point, the upper and lower guide plates 5 and 6 work together to surround the wire. Finally, the first linear module 1 drives the second linear module 2 and its upper structure to move backward to the shaping position. This process straightens the wire, ensuring subsequent shaping. Upon reaching the shaping position, the second linear module 2 continues to drive the lower shaping group 4 upward to the shaping position, and the second linear module 2 continues to drive the upper shaping group 3 downward to the shaping position, squeezing the core wire into the lower shaping group 4 to achieve core wire shaping. In order to consolidate this shape, the first linear module 1 drives the second linear module 2 and its upper structure back and forth several times at this time. The shaping effect is completed, and then the upper shaping group 3 and the lower shaping group 4 are withdrawn, completing the core wire shaping.

[0043] In this way, the positioning, straightening and shaping of the wires are achieved, greatly reducing the intensity of manual labor and avoiding individual differences caused by manual operation. This significantly improves the uniformity and consistency of core wire shaping, making it especially suitable for mass production of high-precision products and greatly improving shaping efficiency.

[0044] The system includes a first spring 7 and a second spring 8. The upper guide plate 5 is slidably connected to the upper shaping group 3. The top of the upper guide plate 5 is connected to the first spring 7, and the top of the first spring 7 is connected to the upper shaping group 3. The lower guide plate 6 is slidably connected to the lower shaping group 4. The bottom of the lower guide plate 6 is connected to the second spring 8, and the bottom of the second spring 8 is connected to the lower shaping group 4. The first spring 7 enables the movement and reset of the upper guide plate 5, ensuring that in the initial state, the bottom of the upper guide plate 5 is below the shaping end of the upper shaping group 3. The second spring 8 enables the movement and reset of the lower guide plate 6, ensuring that in the initial state, the top of the lower guide plate 6 is above the shaping end of the lower shaping group 4.

[0045] The upper guide plate 5 has several first guide grooves 51 spaced apart along its length at its bottom end, and the lower guide plate 6 has several second guide grooves 61 spaced apart along its length at its top end. The first guide grooves 51 and the second guide grooves 61 enclose and form a guide channel 9. The guide channel 9, combined with the first straight module 1, achieves the enclosure and straightening effect of the guide grooves. Furthermore, the first guide grooves 51 and the second guide grooves 61 are processed separately, which can effectively control the surface polishing during processing and avoid the problem of insufficient polishing inside the guide grooves caused by one-piece processing, thus preventing scratches on the wire and ensuring the integrity and surface quality of the wire, providing a high-quality material foundation for subsequent production.

[0046] The lower shaping assembly 4 includes a first mounting base 41, a first cover plate 42, and a first shaping blade 43. The first mounting base 41 is fixed to the lower movable end of the second linear module 2. The first shaping blade 43 is detachably fixed to the first mounting base 41. Both the first mounting base 41 and the first shaping blade 43 have a first receiving groove 44 for accommodating the lower guide plate 6. The first cover plate 42 is detachably connected to the first mounting base 41 and forms a first slide rail 45 with the first receiving groove 44. The lower guide plate 6 is slidably connected to the first slide rail 45. The first shaping blade 43 is detachable, and different first shaping blades 43 can be replaced according to different shaping needs.

[0047] The system also includes a fixed base 10, a first adjusting base 11, a first bolt 12, a third spring 13, a second bolt 14, and a limiting member 15. The fixed base 10 is fixed to the base 100 of the second linear module 2. The first adjusting base 11 is disposed on the fixed base 10 and can move up and down relative to the fixed base 10. The bottom end of the fixed base 10 is screwed with the first bolt 12, and the top end of the first bolt 12 is rotatably connected to the bottom wall of the first adjusting base 11. The bottom wall of the first adjusting base 11 is connected to the third spring 13, and the bottom end of the third spring 13 is connected to the fixed base. The bottom end of the mounting base 10 is connected to the first adjusting seat 11, which has a strip hole 16. The mounting base 10 has a threaded groove 17. The second bolt 14 passes through the strip hole 16 and is inserted into the threaded groove 17 to fix the first adjusting seat 11 to the mounting base 10. The top end of the first adjusting seat 11 is fixed with a limiting member 15. The first mounting base 41 has a through hole 46. The lower guide plate 6 has an extension 62 that passes through the through hole 46. The extension 62 can move up and down relative to the through hole 46. The top end of the limiting member 15 has a stop 151, which is located above the extension 62. Since the lower guide plate 6 needs to support the wire horizontally, the height of the wire support position of the lower guide plate 6 needs to be strictly controlled. However, there are processing errors in the structure during processing and assembly errors during assembly, which will lead to height errors. The limiting member 15 is used to limit the height of the lower guide plate 6, so the height of the limiting member 15 needs to be strictly controlled. This utility model achieves precise control of the height of the lower guide plate through the height-adjustable limiting member 15. Specifically, when the height of the limiting member 15 needs to be adjusted, loosen the second bolt 14, then tighten the first bolt 12 to adjust the vertical position of the first adjusting seat 11, thereby adjusting the vertical position of the limiting member 15. After adjustment, tighten the second bolt 14 to fix the first adjusting seat 11 to the fixed seat 10. The function of the third spring 13 is to push the first adjusting seat 11 upwards and pull the first adjusting seat 11 downwards through the first bolt 12. The height limiting principle of the limiting member 15 for the lower guide plate 6 is as follows: The fixed base 10 is fixed to the base 100 of the second linear module 2, so the height of the limiting member 15 after the position is adjusted remains unchanged. The stop 151 of the limiting member 15 blocks and limits the extension 62 of the lower guide plate 6. When the lower shaping group 4 moves upward, it drives the lower guide plate 6 to move upward until the extension 62 moves upward and abuts against the stop 151. At this time, the position of the lower guide plate 6 is fixed and it remains in the wire support position. Even if the lower shaping group 4 continues to move upward, the lower guide plate 6 cannot continue to move upward.

[0048] The first shaping blade 43 has a groove 431 at its top, and a plurality of shaping teeth 432 spaced apart along its length within the groove 431. The top of the shaping teeth 432 has an inclined surface 433 that slopes outward from top to bottom. By setting the inclined surface 433, the spacing of the wire cores can be adjusted to complete the pin separation process. Specifically, as the wire cores (in this embodiment, the two middle signal wires and the two outer ground wires) enter the groove 431 from the opening, the inclined surface 433 causes the two outer ground wires to bend outward, changing the spacing between the ground wires and the signal wires, thus automatically performing pin separation.

[0049] The upper shaping assembly 3 includes a second mounting base 31, a second cover plate 32, and a second shaping blade 33. The second mounting base 31 is fixed to the upper movable end of the second linear module 2. The second shaping blade 33 is detachably fixed to the second mounting base 31. Both the second mounting base 31 and the second shaping blade 33 have a second receiving groove 34 for accommodating the upper guide plate 5. The second cover plate 32 is detachably connected to the second mounting base 31 and forms a second slide rail 35 with the second receiving groove 34. The upper guide plate 5 is slidably connected to the second slide rail 35. The second shaping blade 33 is detachable, and different second shaping blades 33 can be replaced according to different shaping needs.

[0050] The second shaping blade 33 has several insert plates 331 spaced apart along its length at its bottom end, and the insert plates 331 are offset from the shaping teeth 432. The core wire is squeezed downward into the groove 431 by the insert plates 331, and the shaping operation is achieved in conjunction with the shaping teeth 432.

[0051] The first mounting base 41 and the second mounting base 31 have the same structure, both including a base 100, a mounting bracket 200, a slide bar 300, a third bolt 400, a fourth spring 500, a second adjusting seat 600, a third adjusting seat 700, a positioning pin 800, and a positioning bushing 900. The base 100 is fixed with the positioning pin 800, and the mounting bracket 200 is fixed with the positioning bushing 900. The positioning pin 800 cooperates with the positioning bushing 900. Both the upper and lower parts of the mounting bracket 200 have horizontally arranged slide bars 300. The second adjusting seat 600 and the third adjusting seat 700 are slidably connected to the two slide bars 300 respectively. One end of the mounting bracket 200 is screwed with... Two third bolts 400 are rotatably connected to the side walls of the second adjusting seat 600 and the third adjusting seat 700, respectively. Two sets of fourth springs 500 are connected to the other end of the mounting bracket 200, respectively, and are connected to the second adjusting seat 600 and the third adjusting seat 700, respectively. The first shaping blade 43 is detachably fixed to the second adjusting seat 600 of the first mounting base 41. The first receiving groove 44 is located in the third adjusting seat 700 of the first mounting base 41. The second shaping blade 33 is detachably fixed to the second adjusting seat 600 of the second mounting base 31. The second receiving groove 34 is located in the third adjusting seat 700 of the second mounting base 31. Since the first shaping blade 43, the second shaping blade 33, the upper guide plate 5, and the lower guide plate 6 form a group, they need to be replaced when changing products. Traditionally, this involves replacing four workpieces online, requiring the disassembly and assembly of multiple parts, making replacement difficult and time-consuming. This utility model allows the mounting bracket 200 and base 100 to be assembled and disassembled, making the mounting bracket 200 and its upper structure a single module. Precise positioning is achieved through the positioning pin 800 and positioning bushing 900. The module is pre-assembled offline, and during model changeovers, only the upper and lower modules need to be disassembled and assembled, enabling rapid model changeovers. The third bolt 400 and the fourth spring 500, in conjunction with these components, allow for left-right adjustment to compensate for deviations in line accuracy caused by machining errors.

[0052] The first shaping blade 43 has a slot 434 at its top, and the second shaping blade 33 has a locking block 332 at its bottom that engages with the slot 434. Through the engagement of the slot 434 and the locking block 332, the first and second shaping blades 43 are positioned before the insert plate 331 is inserted into the groove 431, ensuring precise engagement between the insert plate 331 and the shaping teeth 432.

[0053] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
