[0016] The embodiments will be combined with the drawings in the specification to clearly and completely describe the technical solution of the present application. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without making any creative work shall fall within the scope of protection of the present application.

[0017] Embodiment 1: The present invention provides a wire bonding fixture for an optical communication module. Figure 1 - Figure 5 The jig plate 1 is used as a core basic component. The jig plate 1 is provided with a plurality of jig positioning parts 101 arranged in an array. The jig positioning parts 101 are used to fix the optical communication module 2. One end of the optical communication module 2 is connected to a plurality of optical fiber connectors 22 through optical fibers. An upper welding position 21 is provided on the top of the optical communication module 2. The array layout of the jig positioning parts 101 on the jig plate 1 has been carefully designed, taking into full consideration the size specifications, shape characteristics and batch processing requirements of the optical communication module 2 on the production line. This layout can not only efficiently accommodate multiple optical communication modules 2 within the limited area of ​​the jig plate 1, realize parallel brazing processing, and improve production efficiency, but also ensure that each jig positioning part 101 can provide an accurate and consistent positioning environment for the optical communication module 2.

[0018] The fixture positioning portion 101 is provided with a first operating notch 11 and a second operating notch 12. The top of the fixture positioning portion 101 is provided with a lateral limit block for limiting the left and right displacement of the optical communication module 2 and a longitudinal limit block for limiting the front and rear displacement of the optical communication module 2. The lateral limit block includes four groups of lateral bending blocks 15, and the four groups of lateral bending blocks 15 are arranged opposite to each other in pairs. The four groups of lateral bending blocks 15 are arranged between the first operating notch 11 and the second operating notch 12. The longitudinal limit block includes four groups of longitudinal bending blocks 14, and the four groups of longitudinal bending blocks 14 are arranged opposite to each other in pairs. Two sets of longitudinal bending blocks 14 are arranged opposite to each other, wherein two sets of longitudinal bending blocks 14 are arranged in the second operating notch 12, and two sets of supporting bending blocks 121 are arranged opposite to each other on the side of the second operating notch 12 away from the longitudinal bending blocks 14, and the supporting bending blocks 121 are used to support the bottom of the optical communication module 2 and maintain the distance between the optical communication module 2 and the fixture plate 1, and the other two sets of longitudinal bending blocks 14 are arranged on the side of the first operating notch 11 away from the second operating notch 12, and two sets of oblique bending blocks 13 are also arranged on the side of the first operating notch 11 away from the second operating notch 12; The oblique bending block 13, the longitudinal bending block 14, the transverse bending block 15 and the second operating notch 12 are all sheet metal bending structures after laser cutting of the jig plate 1 body. The two groups of oblique bending blocks 13 relatively form a V-shaped groove, and the V-shaped groove is used to limit the displacement of the optical fiber connector 22. The longitudinal bending block 14, the transverse bending block 15 and the supporting bending block 121 are all arranged perpendicular to the upper end surface of the jig plate 1. The bending directions of the longitudinal bending block 14 and the transverse bending block 15 are perpendicular. The thickness positions of the longitudinal bending block 14 and the transverse bending block 15 are both in conflict with the sides of the optical communication module 2. After the longitudinal bending block 14 and the transverse bending block 15 are bent, sheet metal holes 102 are left on the jig plate 1.

[0019] When the present application adopts a single jig plate 1 for sheet metal preparation, the dimensional accuracy of the entire jig plate 1 can be ensured through sheet metal processing techniques such as laser cutting and bending. Since the jig plate 1 is processed from a complete sheet, there is no cumulative dimensional error that may occur when multiple parts are spliced ​​together. For example, for the array arrangement of the jig positioning parts 101, the spacing between each positioning part and the position accuracy relative to the edge of the jig plate 1 can be precisely controlled at the micron level. This is very critical for jigs that require high-precision positioning of optical communication modules 2 for wire welding operations. It can ensure that the position of each optical communication module 2 placed after the jig positioning part 101 is highly consistent, which is beneficial to improving the accuracy and quality of the welding wire.

[0020] At the same time, the single jig plate 1 structure provides better overall rigidity. When using automated wire bonding equipment, certain vibrations and impact forces may be generated. The single jig plate 1 can better resist these external forces and maintain the stability of the jig positioning part 101 and the optical communication module 2. For example, when the welding head of the wire bonding equipment moves at high speed to perform wire bonding operations, the rigidity of the jig plate 1 can prevent the jig positioning part 101 from slight displacement or shaking, thereby ensuring the relative position stability of components such as chips, pins and optical fiber connectors on the optical communication module 2, and avoiding quality problems such as wire dislocation.

[0021] The jig plate 1 of the present invention is prepared by a sheet metal preparation method, and the processing of a single jig plate 1 is relatively simple and efficient. Through laser cutting technology, the shape of the jig plate 1 and structures such as the jig positioning portion 101, operating notches such as the first operating notch 11 and the second operating notch 12 can be quickly cut out from the sheet. Moreover, laser cutting has high precision and can achieve cutting of complex shapes, such as the precise forming of limiting structures such as the oblique bending block 13, the longitudinal bending block 14 and the transverse bending block 15. The subsequent sheet metal bending process can also be carried out in the same machining center or production line, reducing the turnover and coordination time between machining procedures. This efficient processing flow can shorten the production cycle of the jig, which is conducive to rapid production and use, and is particularly suitable for the large demand for welding wire jigs during large-scale production of optical communication modules.

[0022] From the perspective of material cost, the sheet metal preparation of a single jig plate 1 can make full use of the area of ​​the sheet and reduce material waste. Compared with the method of manufacturing and assembling multiple parts separately, no additional connectors such as screws, nuts, pins, etc. and complex assembly tools are required, which reduces material costs and assembly costs. At the same time, since the processing flow is relatively simple, the production cost of the unit jig can be effectively controlled during large-scale production. For example, when mass-producing this optical communication module welding wire jig, by optimizing the sheet metal cutting and bending process, the utilization rate of raw materials can be increased to a higher level, and the cost of manual assembly can be reduced, thereby reducing production costs as a whole and improving the market competitiveness of the product.

[0023] Embodiment 2: The present invention provides a wire bonding fixture for an optical communication module. Figure 6 - Fig.12 , wherein the components identical or corresponding to those in Embodiment 1 are marked with the corresponding reference numerals in Embodiment 1. For the sake of simplicity, only the differences from Embodiment 1 are described below: In this embodiment, a bonding plate 3 is also provided at the bottom of the jig positioning portion 101. After the main body of the bonding plate 3 is laser cut, the sheet metal is bent to form a plurality of guide bending blocks 301. The guide bending blocks 301 correspond to the sheet metal holes 102 one by one. The guide bending blocks 301 are slidably connected in the sheet metal holes 102, thereby ensuring the relative position accuracy between the bonding plate 3 and the jig plate 1, and providing stable guidance and reliable support for the subsequent movement of the elastic plate 4.

[0024] An elastic plate 4 is fixed on the side of the guide bending block 301 opposite to the longitudinal bending block 14 or the transverse bending block 15. The elastic plate 4 is used to fasten the bottom of the optical communication module 2 located in the jig positioning part 101 when the bonding plate 3 is aligned with the bottom of the jig plate 1. A locking actuator is also provided between the bonding plate 3 and the elastic plate 4 for adjusting the distance between the two.

[0025] The locking actuator includes a middle permanent magnetic ring 302 fixed on the bonding plate 3. The bottom of the fixture positioning part 101 is provided with a locking electromagnetic ring 104 that cooperates with the middle permanent magnetic ring 302. The locking electromagnetic ring 104 has a magnetic repulsion force on the middle permanent magnetic ring 302 when powered.

[0026] It should be noted that a deformation buffer portion 42 is provided at the bottom of the elastic plate 4, the top of the elastic plate 4 is an inverted J-shaped structure, an arc groove 41 is provided at the top of the elastic plate 4, and a roller 103 matching the arc groove 41 is fixed to one side of the longitudinal bending block 14 or the transverse bending block 15. A locking pressure head 5 is also provided on the top of the elastic plate 4 close to the optical communication module 2. The center of the arc groove 41 is located at the top of the elastic plate 4 and away from the locking pressure head 5. The deformation buffer portion 42 has an elastic force that drives the top of the elastic plate 4 close to the optical communication module 2. When the deformation buffer portion 42 is in a free state, the roller 103 is located at the bottom of the arc groove 41. At this time, the bonding plate 3 is bonded to the bottom of the jig plate 1.

[0027] In the free state, the elastic plate 4 maintains the elastic force close to the optical communication module 2, and with the cooperation of the arc groove 41 and the roller 103, the elastic force of the elastic plate 4 is automatically used to make the bonding plate 3 fit on the bottom of the jig plate 1. When the optical communication module 2 needs to be placed in the jig positioning part 101, the locking actuator is started, that is, the locking electromagnetic ring 104 is energized to generate a magnetic repulsion force on the central permanent magnet ring 302, so that the bonding plate 3 moves vertically downward away from the jig plate 1 under the guidance of the guide bending block 301. At this time, the roller 103 is relatively displaced to the top of the arc groove 41. Since the position of the roller 103 remains unchanged, the roller 103 presses the elastic plate 4 as a whole to deform around the deformation buffer part 42 away from the optical communication module 2. At this time, the locking pressure head 5 is recovered, and the optical communication module 2 can be directly placed in the jig positioning part 101.

[0028] When the optical communication module 2 is placed, the locking actuator is closed, and the elastic force of the elastic plate 4 is used, in conjunction with the guidance of the roller 103 and the arc groove 41, to move the bonding plate 3 up to fit the bottom of the optical communication module 2. At the same time, the elastic plate 4 is deformed to get close to the optical communication module 2. The elastic plate 4 is flipped to make the locking pressure head 5 snap onto the top edge of the optical communication module 2, which can prevent the optical communication module 2 from being displaced in the vertical direction, and prevent the optical communication module 2 from being displaced due to vibration during operation of the jig plate 1, resulting in deviation in the brazing position, thereby further improving the brazing quality.

[0029] Furthermore, the locking pressure head 5 is a rubber structure with a triangular cross-section. The end of the locking pressure head 5 close to the optical communication module 2 is arc-shaped, which can better fit the surface contour of the optical communication module 2 and reduce the resistance when the optical communication module 2 is placed in the fixture positioning part 101. A deflection axis 43 and a ramp pressure plate 44 are fixed to one side of the top of the elastic plate 4. A deflection hole 51 matching the deflection axis 43 is provided on the locking pressure head 5. A fan-shaped groove 52 matching the ramp pressure plate 44 is provided on the locking pressure head 5. A spring sheet 45 is also clamped between the ramp pressure plate 44 and the fan-shaped groove 52. The spring sheet 45 has an elastic force that drives the locking pressure head 5 to rotate downward around the deflection axis 43.

[0030] When the optical communication module 2 is placed in the jig positioning portion 101 and is subjected to certain external forces such as slight vibration of the jig or force during adjustment, the elastic plate 4 will produce a slight deformation. This deformation is transmitted through the deflection axis 43, the inclined pressure plate 44 and the spring sheet 45, causing the locking pressure head 5 to rotate downward around the deflection axis 43, further increasing the clamping force on the optical communication module 2, thereby effectively preventing the optical communication module 2 from loosening or displacing under any circumstances, thereby ensuring the stability and reliability of the brazing process.

[0031] Embodiment 3: The present invention provides a welding wire fixture for optical communication modules. Fig.13 - Fig.17, wherein the components identical or corresponding to those in Embodiment 1 and Embodiment 2 are marked with the corresponding reference numerals in Embodiment 1 and Embodiment 2. For the sake of simplicity, only the differences from Embodiment 1 and Embodiment 2 are described below: In this embodiment, the jig positioning portion 101 is separated from the jig plate 1 body by laser cutting to form a separate component, and flip shafts 1011 are fixed at both ends of the length direction of the jig positioning portion 101, and a rotating seat 105 matching the flip shaft 1011 is provided in the jig plate 1, and a toggle shaft 1012 is also provided on one side of the end of the jig positioning portion 101; a lower welding position 23 is also provided at the bottom of the optical communication module 2, and a first auxiliary notch 31 matching the first operating notch 11 and a second auxiliary notch 32 matching the second operating notch 12 are provided on the bonding plate 3; a flip actuator 6 for driving multiple groups of jig positioning portions 101 to flip synchronously 180 degrees is provided at the bottom of the jig plate 1.

[0032] The jig positioning part 101 is separated from the jig plate 1 body by laser cutting technology to form an independent component, so that each jig positioning part 101 can be individually cut and formed by the jig plate 1 on high-precision processing equipment, effectively ensuring its dimensional accuracy and shape accuracy, and reducing the use of raw materials. At the same time, in the subsequent use process, the maintenance, replacement or function upgrade operation of individual jig positioning parts 101 also becomes more convenient and efficient, without the need for large-scale transformation or replacement of the entire jig plate 1. The flip shafts 1011 set at both ends of the jig positioning part 101 form a rotating connection structure with the corresponding rotating seat 105 inside the jig plate 1, which provides a stable and reliable mechanical basis for the overall flipping action of the jig positioning part 101.

[0033] The toggle shaft 1012 arranged on one side of the end of the jig positioning part 101 serves as a force transmission interface with the flip actuator 6, transmitting the power required to drive the flip, ensuring that the jig positioning part 101 can achieve an accurate 180-degree flip under the action of the flip actuator 6, meeting the double-sided brazing process requirements of the optical communication module 2. At the same time, the jig positioning part 101 is flipped separately and synchronously in this embodiment. Compared with the method of flipping the jig plate 1 as a whole, the flipping and displacement of the jig positioning part 101 is avoided while keeping the jig plate 1 in place. At the same time, the flipping space required for double-sided brazing is reduced, so that the brazing equipment has a smaller welding downward stroke, which effectively improves the accuracy and efficiency of double-sided brazing.

[0034] It should be noted that the flip actuator 6 includes a base plate 61 fixed to the bottom of the fixture plate 1, and two sets of flip plates 62 are symmetrically rotatably connected to the base plate 61. Both sides of the flip plates 62 are fixed with flip lever arms 63, and the flip lever arms 63 are rotatably connected to the toggle shaft 1012; A flip electromagnetic ring 621 is fixed in the middle of the flip plate 62, and an outer permanent magnetic ring 611 and an inner permanent magnetic ring 612 are fixed on both sides of the flip plate 62 of the substrate 61. The flip electromagnetic ring 621 can change the magnetic pole by changing the direction of the current, and the magnetic properties of the inner permanent magnetic ring 612 and the outer permanent magnetic ring 611 are different.

[0035] Among them, the rotation axis of the flip plate 62 is coaxially arranged with the rotation axis of the jig positioning part 101, and the axial spacing between the flip force arm 63 and the flip plate 62 is equal to half the width of the jig positioning part 101, so as to realize the synchronous and stable flipping of the jig positioning part 101, and meet the strict requirements of the double-sided brazing or other special processes of the optical communication module 2 for the jig flipping function. A torsion spring is also provided in the rotation axis of the flip plate 62, and the torsion spring has the elastic force to drive the two groups of flip plates 62 to flip relative to each other and fit on the substrate 61. The torsion spring not only provides a guarantee for the initial state and reset of the flip plate 62, but also plays a role of buffering and stabilization during the flipping process, thereby ensuring the smoothness and reliability of the flipping action.

[0036] When the magnetic poles of the flipping electromagnetic ring 621 repel the outer permanent magnetic ring 611 and attract the inner permanent magnetic ring 612, the flip plate 62 will be relatively fitted to the bottom of the substrate 61 under the action of the magnetic force and the torsion spring. When the magnetic poles of the flipping electromagnetic ring 621 are attracted to the outer permanent magnetic ring 611 and repel the inner permanent magnetic ring 612, the flip plate 62 will overcome the elastic force of the torsion spring under the magnetic force, and cooperate with the repulsive force generated by the two groups of flipping electromagnetic rings 621, thereby driving the flipping force arm 63 and the fixture positioning part 101 to flip, thereby realizing the overall synchronous flipping of multiple fixture positioning parts 101.

[0037] The jig positioning part 101 of the present application limits the optical communication module 2 from multiple directions through structures such as the transverse bending block 15, the longitudinal bending block 14, the support bending block 121 and the oblique bending block 13 bent by sheet metal. It has low production cost, small size and is easy to replace. At the same time, it can control the position deviation of the optical communication module 2 in three-dimensional space within the design range, achieve high-precision positioning, ensure the relative position accuracy between the chip and pins, optical fiber connectors and other components during the wire welding process, effectively avoid problems such as wire misalignment and cold welding, improve the electrical performance and signal transmission quality of the optical communication module 2, reduce the defective rate, and improve the product's qualification rate and reliability. The jig plate 1 and the bonding plate 3 provide stable support and clamping force for the optical communication module 2 through the synergistic effect of the guide bending block 301 and the elastic plate 4. During the long production process, even if it is affected by slight external vibrations or temperature changes, the jig can still keep the position of the optical communication module 2 stable, preventing the optical communication module 2 from being displaced vertically when the jig positioning part 101 is flipped, thereby ensuring the positioning consistency of each module during welding, making the product quality highly repeatable, which is conducive to large-scale standardized production, has market prospects, and is suitable for promotion and application.

[0038] The above is only the best implementation method adopted by this application in combination with current actual needs, but the protection scope of this application is not limited to this.
