Description

Technical Field

[0001] This invention relates to the field of optical module OSA manufacturing technology, and in particular to an optical module OSA shaping and trimming fixture. Background Technology

[0002] With the deep penetration of optical communication technology in data centers, 5G communication, fiber broadband and other fields, optical modules, as the core components for realizing the conversion between optical signals and electrical signals, have seen precision control and efficiency improvement in their manufacturing become key factors in ensuring the stability of signal transmission in communication systems and reducing the cost of large-scale mass production. Among the core components of an optical module, the optical signal receiver (OSA) is the core unit for realizing optical signal reception and electrical signal conversion. It is assembled from the optical module body and metal pins (e.g., ...). Figure 1 (As shown in the diagram). The metal pins (typically made of copper alloy with excellent conductivity) serve as the signal transmission medium and must form a stable connection with the circuit structure of the optical module body. In the complete production process of the optical module OSA, after the optical module body and metal pins are initially assembled, two key post-processing steps—bending and shaping, and trimming—are performed on the metal pins. The core purpose of the bending and shaping process is to bend the metal pins, which have been assembled with the optical module body, to a preset angle to meet the installation space requirements of the optical module OSA. The trimming process, on the other hand, requires trimming the bent metal pins to a preset length, removing excess metal pin portions to meet the overall dimensional specifications of the optical module OSA. In the current production process of optical module OSA, the industry generally adopts a "dual-station step-by-step execution" operation mode for the two post-processing steps mentioned above. The specific process is as follows: First, the optical module body and metal pins are initially assembled by automated assembly equipment to form a complete optical module OSA semi-finished product. Then, the optical module OSA semi-finished product is transferred to the bending and shaping station by a robotic arm. The bending and shaping station is equipped with a special bending fixture adapted to the shape of the optical module OSA. After bending is completed, the optical module OSA semi-finished product needs to be removed from the bending fixture by a robotic arm again, ready to be transferred to the next station. Second, the bent optical module OSA semi-finished product is transferred to a special trimming station to trim the length of the bent metal pins, finally forming a qualified optical module OSA finished product. However, in practical applications, the split-site operation mode has obvious defects, which are specifically shown as follows: 1) the OSA semi-finished product of the optical module needs to be transported between two workstations, which not only increases the process interval time, but also needs to additionally configure the corresponding transportation equipment and operating manpower, and it is difficult to meet the beat demand of the large-scale production of the optical module industry; 2) even if there is only slight vibration or positioning deviation during the transportation process, the position of the metal pin relative to the cutting tool may be offset, and then the metal pin trimming may be out of tolerance, and if external force impact is encountered, the already bent metal pin may be deformed again, which affects the assembly quality of the OSA of the optical module, and even causes subsequent performance failure of the optical module.

[0003] Therefore, it is urgent for technical personnel to solve the above problems. SUMMARY

[0004] The purpose of the present application is to provide an optical module OSA shaping and pin cutting tool, which aims to solve the problems of low production efficiency, easy trimming of metal pins out of tolerance and secondary deformation caused by the need to split double workstations to perform metal pin bending and shaping and cutting in the existing design, and high equipment cost and space occupation, realize the integration of two processes, improve the production efficiency and processing precision, and adapt to the demand of large-scale production.

Detailed Implementation

[0034] In the description of this invention, it should be understood that the terms "left", "right", "front", "rear", "up", "down", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and 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. Therefore, they should not be construed as limitations on this invention.

[0035] The invention will be further described in detail below with reference to specific embodiments. The optical module OSA shaping and trimming fixture is specifically designed for bending, shaping, and trimming the metal pins of optical module OSA. For example... Figure 2 , Figure 3 As shown, the OSA shaping and trimming fixture integrates multiple processing steps into an organic system through the overall coordination of the base 1, positioning and clamping mechanism 2, shaping and trimming mechanism 3, clamping drive unit 4, and shaping and trimming operation drive unit 5. This solves the problems of cumbersome process connection and difficulty in controlling precision in traditional decentralized processing from a structural perspective, providing efficient and stable equipment support for the large-scale production of OSA modules.

[0036] Combination Figures 2-4 As can be seen, the base 1 mainly consists of a base body 11, a left mounting plate 12, and a right mounting plate 13. The base body 11 serves as an integral load-bearing frame. The left mounting plate 12 and the right mounting plate 13 are parallel to each other and spaced at a predetermined distance. They provide precise mounting references for the shaping and trimming mechanism 3 and the clamping drive unit 4, respectively, ensuring that the assembly positions of each functional component are accurately aligned. The positioning and clamping mechanism 2 is responsible for positioning and fixing the optical module OSA, while the clamping drive unit 4 provides power transmission for it. The two work together to achieve stable constraint during the workpiece processing, preventing workpiece displacement and processing errors. The shaping and trimming mechanism 3 uses the left mounting plate 12 as its mounting base and is connected to the shaping and trimming operation drive unit 5 to jointly complete the bending and trimming operations of the metal pins. Furthermore, the optical module OSA shaping and trimming fixture is equipped with a foot switch 6 for convenient control of starting and stopping the operation. This lays a structural foundation for efficient operation and precision assurance, significantly reduces the overall footprint of the tooling, improves the utilization rate of workshop space, and eliminates the need for multiple independent equipment sets. Multiple processing steps can be achieved through a single system, greatly reducing equipment procurement and subsequent maintenance costs.

[0037] like Figure 5 , Figure 6 ,like Figure 15 , Figure 16 As shown, the positioning and clamping mechanism 2 includes a front clamping component 21 and a rear clamping component 22 arranged opposite to each other. The front clamping component 21 consists of a front longitudinal sliding block 211, a front clamping claw 212, a front slide rail slider assembly 213, a front screw 214, and a front positioning pin 215. The front clamping claw 212 is precisely aligned with the front longitudinal sliding block 211 via the front positioning pin 215. The two front positioning pins 215 are symmetrically distributed on both sides of the front screw 214, effectively avoiding assembly misalignment. They are then fastened together by the front screw 214 to ensure the installation accuracy of the front clamping claw 212. The front slide rail slider assembly 213 is located between the base 11 and the front longitudinal sliding block 211, providing directional guidance for the forward and backward movement of the front longitudinal sliding block 211, preventing jamming or misalignment during sliding.

[0038] The rear clamping component 22 consists of a rear longitudinal sliding block 221, a rear clamping claw 222, a rear slide rail slider assembly 223, a rear screw 224, and a rear locating pin 225. The rear clamping claw 222 is precisely aligned with the rear longitudinal sliding block 221 via the rear locating pins 225. The two rear locating pins 225 are symmetrically distributed on both sides of the rear screw 224 to eliminate positional deviations during assembly and ensure the relative positional accuracy between the rear clamping claw 222 and the rear longitudinal sliding block 221. After positioning, the rear clamping claw 222 is securely connected to the rear longitudinal sliding block 221 by the rear screw 224, ensuring that the two will not loosen relative to each other during operation. The rear slide rail slider assembly 223 is installed between the base 11 and the rear longitudinal slide block 221. Its slider part is fixedly connected to the rear longitudinal slide block 221, and its slide rail part is fixedly connected to the base 11. Through the matching sliding of the slider and the slide rail, it provides stable guidance for the back and forth movement of the rear longitudinal slide block 221, avoiding problems such as jamming, offset or tilting of the rear longitudinal slide block 221 during the sliding process.

[0039] In practical applications, the relative or opposite movements of the front clamping component 21 and the rear clamping component 22 achieve stable positioning or rapid release of the optical module OSA, ensuring no workpiece displacement deviation during processing and providing a prerequisite guarantee for subsequent bending and trimming accuracy. Furthermore, the symmetrical positioning and clamping design, combined with a precise assembly and guiding structure, keeps the positioning error of the optical module OSA within a minimal range, laying the foundation for improved processing efficiency and guaranteed product yield.

[0040] The clamping drive unit 4 serves as the power source for the positioning and clamping mechanism 2, such as... Figure 5 , Figure 6 As shown, it includes a right-side cylinder 41, a first-stage linkage mechanism 42, a yaw seat 43, a front-side second-stage linkage mechanism 44, and a rear-side second-stage linkage mechanism 45. The yaw seat 43 uses the right-side mounting base 13 as its mounting foundation and freely performs yaw motion when subjected to rotational torque. The right-side cylinder 41 is lowered and fixed to the base 11, and its power output end is connected to the first-stage linkage mechanism 42, transmitting linear motion to the first-stage linkage mechanism 42. The first-stage linkage mechanism 42 then transmits power to the yaw seat 43, causing the yaw seat 43 to perform yaw motion around the hinge point. The front and rear power output ends of the yaw seat 43 are hinged to the front-side second-stage linkage mechanism 44 and the rear-side second-stage linkage mechanism 45, respectively, and synchronously drive the second-stage linkage mechanism 44 and the rear-side second-stage linkage mechanism 45 to change their posture through the yaw motion.

[0041] Similarly, Figure 5 , Figure 6As shown, the front-mounted secondary linkage transmission mechanism 44 consists of a front-mounted secondary transmission component 441 and a front-mounted lateral drive rod 442. One end of the front-mounted secondary transmission component 441 is hinged to the front power output end of the yaw seat 43, and the other end is hinged to the front-mounted lateral drive rod 442, converting the rotational motion of the yaw seat 43 into the attitude deflection motion of the front-mounted lateral drive rod 442. The front-mounted lateral drive rod 442 is laterally inserted into the adapter hole opened on the front-mounted longitudinal sliding block 211, and can perform lateral sliding motion relative to the front-mounted longitudinal sliding block 211. When the front-mounted secondary transmission component 441 changes attitude, the front-mounted lateral drive rod 442 applies a lateral force to the front-mounted longitudinal sliding block 211, driving the front-mounted longitudinal sliding block 211 to slide back and forth along the slide rail direction of the front-mounted slide rail slider assembly 213.

[0042] The rear-mounted secondary linkage transmission mechanism 45 consists of a rear-mounted secondary transmission component 451 and a rear-mounted lateral drive rod 452. One end of the rear-mounted secondary transmission component 451 is hinged to the rear power output end of the yaw seat 43, and the other end is hinged to the rear-mounted lateral drive rod 452, converting the rotational motion of the yaw seat 43 into the attitude deflection motion of the rear-mounted lateral drive rod 452. The rear-mounted lateral drive rod 452 is laterally inserted into the adapter hole opened on the rear-mounted longitudinal sliding block 221, and can perform lateral sliding motion relative to the rear-mounted longitudinal sliding block 221. When the rear-mounted secondary transmission component 451 changes attitude, the rear-mounted lateral drive rod 452 applies a lateral force to the rear-mounted longitudinal sliding block 221, driving the rear-mounted longitudinal sliding block 221 to slide back and forth along the slide rail direction of the rear slide rail slider assembly 223.

[0043] Through this power transmission and motion conversion design, on the one hand, the synchronous movement of the front clamping component 21 and the rear clamping component 22 is achieved, reducing the number of power components used, lowering the overall cost of the equipment, and avoiding the problem of asynchronous movement that may occur from multiple power sources, further ensuring positioning accuracy; on the other hand, the clamping and releasing action of the optical module OSA can be completed quickly, shortening the preparation and finishing time of the operation, and providing support for increasing the processing quantity per unit time.

[0044] like Figures 7-9 As shown, and in combination Figure 2 , Figure 3 It can be seen that the shaping and shortening mechanism 3 uses the left mounting base plate 12 as the mounting base, and includes a bending and shaping component 31, a shortening blade 32 and a guide component 33. The three work together to realize the continuous processing of metal pins by "shaping first and then shortening".

[0045] The bending and shaping assembly 31 consists of a transverse sliding seat 311 and a bending and shaping plate 312. For example... Figure 10As shown, the transverse sliding seat 311 is a one-piece casting with high structural strength and stable dimensional accuracy, making it resistant to deformation under external forces. The mounting groove 3112 on its top is precisely matched to the outer dimensions of the bending and shaping plate 312. After the bending and shaping plate 312 is embedded in the mounting groove 3112, precise positioning is achieved. The number, diameter, and spacing of the process through holes 3121 formed on the bending and shaping plate 312 are perfectly matched to the number, diameter, and spacing of the OSA metal pins of the optical module, ensuring that the metal pins can be smoothly inserted into the holes and that the bending angle of the pins will not be offset due to hole position deviation during processing. The transverse sliding guide groove 3111 formed on the left side wall of the transverse sliding seat 311 has a groove width that matches the outer dimensions of the cutting blade 32, providing a guide channel for the sliding of the cutting blade 32. An extended load-bearing part 3113 extends from the lower left side wall of the transverse sliding seat 311. The extended load-bearing part 3113 transversely passes through the left mounting base plate 12. Its end face has high flatness and can stably receive external thrust, thereby driving the entire bending and shaping assembly 31 to move smoothly in the transverse direction.

[0046] The shaving blade 32 traverses laterally through the left mounting substrate 12 and penetrates the left side wall of the transverse sliding seat 311. Its blade is made of high-strength alloy material to ensure that no pin deformation or burrs occur during the shaving process. The shaving blade 32 is embedded in the transverse sliding guide slot 3111 of the transverse sliding seat 311 and can slide stably along the slot direction without vertical movement or horizontal deviation during the sliding process. Its length is adapted to the distribution width of the optical module OSA metal pins and completes the shaving operation of all metal pins in one go, ensuring that the pin length after shaving meets the design standard.

[0047] like Figure 9 As shown, the guide assembly 33 consists of a front guide rod 331 and a rear guide rod 332. The front guide rod 331 and the rear guide rod 332 have the same diameter and are spaced a predetermined distance apart along the front-to-back direction, the distance matching the front-to-back length of the transverse sliding seat 311. The front guide rod 331 and the rear guide rod 332 are respectively inserted into guide holes at the front and rear ends of the transverse sliding seat 311, effectively restricting the movement direction of the transverse sliding seat 311; and the two ends of the front guide rod 331 and the rear guide rod 332 are respectively fixed to the left mounting base 12 and the right mounting base 13, ensuring that they do not experience axial movement or radial offset. Through the synergistic effect of the front guide rod 331 and the rear guide rod 332, bidirectional directional constraints are provided for the transverse movement of the transverse sliding seat 311, preventing offset or wobbling during movement and ensuring consistency between the bending angle and the shortened length.

[0048] In practical applications, the processing precision of metal pins has been greatly improved, with bending angle error controlled within ±0.5° and shortening length error controlled within ±0.1mm. This effectively avoids optical module OSA assembly failures caused by processing deviations, significantly improving product qualification rate. At the same time, continuous processing design eliminates the need for manual process switching, shortens the processing cycle, and further improves work efficiency.

[0049] like Figure 9 , 11 As shown in Figures 1-14, the shaping and shortening operation drive unit 5 serves as the power core of the shaping and shortening mechanism 3. It mainly consists of a left-side cylinder 51, a pushing sliding member 52, a guide block 53, a left-side elastic reset assembly 54, and a right-side elastic reset assembly 55. The guide block 53 is placed and fixed to the base 11, and has a guide sliding groove 531 that matches the pushing sliding member 52. The cross-sectional shape of the guide sliding groove 531 is consistent with the cross-sectional shape of the pushing sliding member 52, and the fitting clearance is controlled within a small range, limiting the movement direction of the pushing sliding member 52 and preventing the power transmission effect from being affected by movement deviation. The pushing sliding member 52 is embedded in the guide sliding groove 531, and its surface has been precision ground, resulting in low sliding friction and allowing it to move smoothly along the guide sliding groove 531.

[0050] The left-side cylinder 51 is also mounted on the base 11, and its piston rod is connected to the push-pull sliding member 52, allowing the left-side cylinder 51 to stably drive the push-pull sliding member 52 to move back and forth along the guide sliding groove 531. The front power output end of the push-pull sliding member 52 has an upper side push-wedge surface 521 and a lower side push-wedge surface 522 formed sequentially along the height direction. Both the upper side push-wedge surface 521 and the lower side push-wedge surface 522 are precision machined, with low surface roughness, reducing friction and wear with the contacting parts. Along the sliding direction of the pusher sliding member 52, the lower side push wedge surface 522 is positioned further forward than the upper side push wedge surface 521. Therefore, when the pusher sliding member 52 slides forward, the lower side push wedge surface 521 first contacts the outer bearing portion 3113 of the transverse sliding seat 311 and applies a lateral thrust, causing the transverse sliding seat 311 to slide laterally under the coordinated guidance of the front guide rod 331 and the rear guide rod 332. During the process, the metal pins passing through the process through holes 3121 of the bending and shaping plate 312 are bent by the constraint of the hole wall, completing the shaping operation; as the push sliding member 52 continues to slide forward, the upper side push wedge surface 522 contacts the cutting knife 32 again and applies a side thrust, driving the cutting knife 32 to move laterally along the lateral sliding guide groove 3111 of the lateral sliding seat 311, performing a cutting operation on the bent metal pins, and precisely controlling the pin length.

[0051] like Figure 11 , Figure 12As shown, the left-positioned elastic reset assembly 54 consists of a pull bolt 541 and a left-positioned columnar spring 542. The pull bolt 541 passes through the guide block 53 and can move freely laterally when subjected to force; the right end of the pull bolt 541 is fixedly connected to the cutting blade 32 via a threaded joint. The left-positioned columnar spring 542 is sleeved on the pull bolt 541, with one end abutting against the end of the pull bolt 541 (left end) and the other end abutting against the left side wall of the guide block 53. At this time, the left-positioned columnar spring 542 is in an elastically compressed state, pre-storing elastic potential energy. When the cutting blade 32 performs lateral sliding under the drive of the push sliding member 52, preparing to cut the metal pin, the cutting blade 32 will simultaneously pull the left-positioned columnar spring 542 to the left through the pull bolt 541, so that the left-positioned columnar spring 542 continues to be compressed, and its stored elastic potential energy increases accordingly, reserving sufficient power for the subsequent reset of the cutting blade 32.

[0052] As Figure 9 As shown, the main component of the right-positioned elastic reset assembly 55 is a right-positioned columnar spring 551. One end of the right-positioned columnar spring 551 is fixed to the right-positioned mounting base 13 of the base 1 via a spring seat. The left end face of the right-positioned columnar spring 551 corresponds to the right side wall of the transverse sliding seat 311. When the transverse sliding seat 311 performs a rightward transverse movement, the right-positioned columnar spring 551 is compressed and stores elastic potential energy; when the pushing sliding member 52 is reset backward, the right-positioned columnar spring 551 releases its elastic potential energy, applies an elastic lateral thrust to the transverse sliding seat 311, and pushes the transverse sliding seat 311 together with the bending and shaping plate 312 back to the initial position, preparing for the next processing.

[0053] The working principle of the optical module OSA shaping and trimming fixture is roughly as follows: Before the operation starts, the optical module OSA to be processed is placed between the front clamping component 21 and the rear clamping component 22 with the help of a robotic arm, so that the metal pins at the bottom of the optical module OSA face down and are inserted one by one into the process through hole 3121 of the bending and shaping plate 312. Visual observation is used to ensure that each pin is completely inserted into the hole, and the end face of the optical module OSA is parallel to the clamping surfaces of the front clamping claw 212 and the rear clamping claw 222, ensuring that the pin position is accurately aligned with the processing path.

[0054] The operator then operates foot switch 6 to start the fixture: First, the right-side cylinder 41 of the clamping drive unit 4 is activated, the piston rod extends and pushes the first-stage linkage transmission mechanism 42 to move. The first-stage linkage transmission mechanism 42 converts the linear motion into the rotational motion of the yaw seat 43, causing the yaw seat 43 to yaw around its hinge point with the right-side mounting base 13. During the yaw process, the yaw seat 43 synchronously drives the front-side second-stage linkage transmission mechanism 44 and the rear-side second-stage linkage transmission mechanism 45 to move. Mechanism 44 pushes the front longitudinal sliding block 211 to slide forward along the front slide rail slider assembly 213, and the rear secondary linkage transmission mechanism 45 pushes the rear longitudinal sliding block 221 to slide backward along the rear slide rail slider assembly 223, thereby driving the front clamping claw 212 and the rear clamping claw 222 to move closer to the optical module OSA in sync, until the clamping surfaces of the front clamping claw 212 and the rear clamping claw 222 are tightly fitted with the front and rear end faces of the optical module OSA, stably clamping the optical module OSA and completing the workpiece positioning and fixing.

[0055] Next, the left cylinder 51 of the shaping and shortening operation drive unit 5 is activated, and the piston rod extends to push the push sliding member 52 forward along the guide sliding groove 531. Because the lower side push wedge surface 521 of the push sliding member 52 is positioned further forward, it first contacts the outer bearing part 3113 of the transverse sliding seat 311. As the push sliding member 52 continues to move forward, the lower side push wedge surface 521 applies a transverse lateral thrust to the outer bearing part 3113, causing the transverse sliding seat 311 to move laterally to the right under the coordinated guidance of the front guide rod 331 and the rear guide rod 332. During this process, the metal pins passing through the process through hole 3121 of the bending and shaping plate 312 are constrained by the hole wall of the process through hole 3121 and gradually bend with the movement of the transverse sliding seat 311 to form a preset angle, thus completing the bending and shaping process.

[0056] The pusher slide member 52 continues to move forward. When its upper side push wedge surface 522 contacts the cutting blade 32, the upper side push wedge surface 522 applies a lateral push force to the cutting blade 32, driving the cutting blade 32 to move laterally to the right along the lateral sliding guide groove 3111 of the lateral sliding seat 311. During the movement, the cutting blade 32 contacts the bent metal pin and cuts off the part of the metal pin that exceeds the preset length, so that the pin length meets the design requirements and the cutting process is completed.

[0057] After the metal pins are processed, the piston rod of the left cylinder 51 retracts, causing the push sliding member 52 to reset backward. At this time, the left columnar spring 542 releases elastic potential energy and applies elastic pulling force to the cutting blade 32 through the pull bolt 541, causing the cutting blade 32 to reset to the left along the transverse sliding guide groove 3111. At the same time, the right columnar spring 551 releases elastic potential energy to apply elastic lateral thrust to the transverse sliding seat 311, thereby pushing the transverse sliding seat 311 together with the bending and shaping plate 312 to reset and return to the initial position.

[0058] Subsequently, the piston rod of the right-side cylinder 41 retracts, driving the first-stage linkage transmission mechanism 42 to move in the opposite direction, which in turn drives the tilting seat 43 to tilt in the opposite direction. The tilting seat 43, through the front second-stage linkage transmission mechanism 44 and the rear second-stage linkage transmission mechanism 45, pulls the front longitudinal sliding block 211 and the rear longitudinal sliding block 221 to move in opposite directions, causing the front clamping claw 212 and the rear clamping claw 222 to move away from the optical module OSA, thus releasing the clamping constraint on the optical module OSA. Finally, with the help of a robotic arm, the processed optical module OSA is removed from the fixture. At this point, the optical module OSA shaping and trimming fixture has completed one complete processing cycle and can proceed to the next round of operation.
