Description

Technical Field

[0001] This invention relates to the field of optical communication device manufacturing technology, and in particular to an automatic laser spot welding machine for SFP28 optical module spring contacts. Background Technology

[0002] In modern optical communication networks, the SFP28 optical module is a key component for achieving high-speed photoelectric conversion of 25Gbps. During its assembly, metal contacts for electrical grounding or electromagnetic shielding need to be precisely and reliably soldered to specific locations on the module housing, typically including the top, bottom, and sides. The precision and consistency of this soldering process directly determine the module's electrical contact performance, shielding effectiveness, and long-term reliability.

[0003] Currently, this process mainly relies on manual labor or semi-automated equipment. A typical procedure involves operators manually placing the optical module into a fixture, relying on visual inspection and experience to pre-position millimeter-sized spring clips on the welding surfaces of the module housing, and then operating a laser welding machine for spot welding. To complete welding on multiple sides of the module, repeated manual flipping, repositioning, and clamping of the module are required.

[0004] However, the aforementioned manual operation mode has significant limitations. First, manual operation is slow and the transitions between processes are disjointed, making it difficult to integrate into high-speed automated production lines and becoming a major constraint on overall output. Second, the placement, orientation, and fit of the spring contacts to the housing are highly dependent on the operator's skill and condition, easily leading to problems such as positional misalignment and spring contact warping, resulting in unstable welding quality and large fluctuations in product yield. Furthermore, to achieve multi-sided welding, multiple manual interventions for flipping and transferring are required, making it impossible to achieve a continuous, integrated automated production process. Frequent close-range operation of the laser equipment by personnel also poses safety hazards. Summary of the Invention

[0005] The purpose of this invention is to solve the technical problems mentioned in the background art regarding the welding process of multi-faceted spring contacts in SFP28 series optical modules, which relies on manual labor, is inefficient, has difficulty in guaranteeing accuracy, and cannot be continuously automated.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: An automatic laser spot welding machine for SFP28 optical module spring contacts includes a machine body, and further includes: a feeding module for conveying the optical module product to be welded; a positioning and gripping module for gripping and positioning the optical module product; a first carrier transfer module and a second carrier transfer module, disposed on the machine body, the first carrier transfer module having a first product carrier and the second carrier transfer module having a second product carrier; at least two sets of feeding modules corresponding to the welding station for supplying spring contact strips; at least two sets of spring contact cutting and feeding modules corresponding to the feeding modules for cutting the strip into spring contacts and transferring them to the surface to be welded of the optical module product; a first spring contact pressing module and a second spring contact pressing module for pressing the spring contacts onto the surface to be welded; a laser module for welding the pressed spring contacts; and a laser module disposed on the machine body for driving the first product carrier and / or the second product carrier.

The first carrier transfer module, the first product carrier, the corresponding spring sheet cutting and feeding module, the first spring sheet pressing module, the laser module, and the carrier rotation module collectively constitute a first welding station for welding the upper and lower surfaces of the product. The pusher module, transfer module, second carrier transfer module, second product carrier, the corresponding spring sheet cutting and feeding module, the second spring sheet pressing module, the laser module, and the carrier rotation module collectively constitute a second welding station for welding the side surfaces of the product, thereby achieving continuous automated welding of the multi-sided spring sheets of the optical module product.

[0007] Preferably, the feeding module includes a feeding belt and a first cylinder and a second cylinder arranged thereal and operating alternately to form an interleaved feeding mechanism.

[0008] Preferably, the positioning and gripping module includes a drive module, a suction cup that is lifted and lowered by the drive module, a third cylinder that drives the suction cup to move horizontally, and a pusher and a fourth cylinder for receiving the product and pushing it toward the first product carrier.

[0009] Preferably, the spring sheet cutting and feeding module includes a servo feeding mechanism for a stepping conveyor belt, a cutting mechanism for cutting the spring sheets, and a precision transfer mechanism for transferring the spring sheets.

[0010] Preferably, the servo feeding mechanism includes a feeding ratchet driven by a fourth servo motor, the cutting mechanism includes a cutting blade driven by a fifth cylinder, and the precision transfer mechanism includes a first linear transfer rail driven by a fifth servo motor, a second linear transfer rail driven by a sixth servo motor, and a gripper mounted on the second linear transfer rail that is lifted by a sixth cylinder and gripped by a seventh cylinder.

[0011] Preferably, the carrier rotation module includes a clamp, an eighth cylinder for driving the clamp to clamp or release, and a first rotation drive unit for driving the clamp together with the clamped product carrier to rotate.

[0012] Preferably, the transfer module includes a positioning carrier for carrying the product, a second rotary drive unit for driving the positioning carrier to rotate, and a rack and pinion transmission mechanism for driving the entire transfer module to move linearly to transfer the product to the second product carrier.

[0013] Preferably, the unloading rotary module includes an unloading conveyor line, a movable gripper cylinder, and a drive component that drives the gripper cylinder to move and rotate to transfer the product to the unloading conveyor line.

[0014] Preferably, it further includes at least one set of detection modules, which are used to detect at least one of the following: the transfer position of the spring piece, the in-situ status of the optical module product, and the positioning attitude, and the detection signal is fed back to the control system of the automatic machine.

[0015] Preferably, it also includes a human-machine interaction module, which is used to set welding process parameters, display the operating status of each module and sensor detection information, and receive operation commands.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This invention achieves continuous production from material loading and multi-sided welding to material unloading through the collaboration of multiple automated modules and the relay of two welding stations, thereby replacing inefficient and intermittent manual operations and significantly improving production cycle time. The use of a servo-driven precision transfer mechanism and a contour-following clamping mechanism ensures absolute accuracy in the placement and bonding of the spring pieces, avoiding human error and ensuring stable and reliable welding quality. The fully enclosed automated operation prevents personnel from contacting the laser equipment, while the automatic flipping and transfer mechanism enables seamless multi-sided welding, forming a safe and continuous production process.

The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the invention.

They are merely simplified descriptions for the convenience of describing this invention and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation.

[0026] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0027] Please see Figures 1-15 An automatic laser spot welding machine for SFP28 optical module spring sheets includes a main body 1 and various functional modules integrated thereon. The main body 1 is typically a rigid welded frame covered with a safety shield, forming a clean and safe working space inside. The modules are arranged around two core product carriers, a first product carrier 23 and a second product carrier 24, forming two collaborative welding stations. From a process flow perspective, a feeding module 3 is set at one end of the equipment, and a feeding rotation module 13 is set at the other end. Along the product flow path in the middle area, a positioning and gripping module 4, a first carrier transfer module 2 and its first product carrier 23, a carrier rotation module 9, a pushing module 10, a transfer module 11, a second carrier transfer module 21 and its second product carrier 24 are sequentially arranged. The spring sheet supply and processing system includes a feeding module 5 and a spring sheet cutting and feeding module 6, which are usually symmetrically arranged on both sides of the main body 1, serving the upper and lower surface welding stations and the side welding stations, respectively. The laser module 8 can be mounted on a gantry or a moving slide, allowing its laser head to be precisely moved above the welding points of the two workstations. The first spring clip module 7 and the second spring clip module 12 are respectively set up for the two workstations. In addition, the equipment also integrates a detection module 14 and a human-machine interface module 15, which together form an intelligent and monitorable closed-loop control system.

[0028] The feeding module 3 mainly includes a feeding belt 31. Along the conveying direction of the feeding belt 31, stops driven by a first cylinder 311 and a second cylinder 312 are spaced apart. These two cylinders operate alternately under the control of the control system; when one extends to block a product, the other retracts, forming an interleaved feeding mechanism. This structure effectively separates and supplies products one by one, preventing product accumulation on the belt and ensuring that the positioning and gripping module 4 grips only one product at a time.

[0029] The positioning and gripping module 4 is responsible for gripping the product from the end of the feed belt 31 and precisely positioning it on the first product carrier 23. It includes a third cylinder 41 for driving the entire gripping component to move horizontally. The drive module 42, typically a servo motor-driven lead screw slide, is responsible for the precise lifting and lowering of the suction cup 43. The suction cup 43 picks up the product via vacuum suction. At the end of the horizontal movement path, a fixed pusher carrier 45 is provided, with a push plate driven by a fourth cylinder 44 on its side. When the suction cup 43 carrying the product descends to the pusher carrier 45, the vacuum is released, and the product falls onto the carrier. Subsequently, the fourth cylinder 44 actuates, precisely pushing the product into the positioning slot of the waiting first product carrier 23. This process solves the problems of low efficiency and inaccurate positioning associated with manual loading.

[0030] The first carrier shifting module 2 and the second carrier shifting module 21 have the same structure, both being high-precision linear modules, as shown in Figure 3, driven by a lead screw slide of the first servo motor 22. The first product carrier 23 is fixed on the slide of the first carrier shifting module 2, and the second product carrier 24 is fixed on the slide of the second carrier shifting module 21. Each product carrier is equipped with a contour positioning groove that matches the shape of the SFP28 optical module, which can accommodate all sizes of SFP28 optical modules from 2×1 to 2×12. All 12 products can share this carrier, thus enabling rapid adaptation and ensuring that the products do not shift during movement and flipping, greatly improving the compatibility of the equipment.

[0031] like Figure 5 As shown, each feeding module 5 mainly includes a feeding rack 52 for suspending the tray-mounted spring terminal material tray 51. In a preferred embodiment, the rotating shaft of the terminal material tray 51 is connected to a third servo motor 53, forming an active feeding mechanism. Below the material strip exit path, there is a detection copper rod 54 that can swing slightly. When the third servo motor 53 feeds too much material, causing the material strip to sag and touch the detection copper rod 54, the contact signal is fed back to the control system, controlling the third servo motor 53 to stop, thereby maintaining the material strip at a suitable tension and preventing the material strip from being pulled or excessively piled up.

[0032] The spring sheet cutting and feeding module 6 mainly includes a servo feeding mechanism, a cutting mechanism, and a precision transfer mechanism, such as... Figure 6 , Figure 7 and Figure 8As shown, the servo feeding mechanism is driven by a fourth servo motor 61 to a feeding ratchet 611. The ratchet teeth are embedded in the positioning holes of the material strip, achieving precise step-by-step conveying of the material strip. The cutting mechanism is driven by a fifth cylinder 63 to a cutting blade 631. After the servo feeding mechanism completes the feeding, it performs punching to separate individual spring pieces from the material strip. The precision transfer mechanism is used to grab the cut spring pieces and transfer them to the product's welding surface. It adopts a five-axis servo drive platform. The fifth servo motor 62 drives the first linear guide rail 621 to move in the X direction, and the sixth servo motor 66 mounted on it drives the second linear guide rail 661 to move in the Y direction. The gripper 64 mounted on the second linear guide rail 661 is driven by a sixth cylinder 65 to move in the Z direction, and the seventh cylinder 67 drives the gripper to open and close to grab or release the spring pieces. This structure can accurately place the spring pieces in a predetermined position in three-dimensional space, which replaces manual placement of spring pieces and fundamentally solves the problems of poor placement accuracy and low consistency of spring pieces.

[0033] The first spring clip module 7 and the second spring clip module 12 have the same structure and function. After the spring clip is transferred to the product surface, the cylinder of the spring clip module drives a pressure rod with a contoured pressure head to descend, tightly pressing the spring clip onto the optical module housing, eliminating gaps and providing optimal conditions for laser welding. The laser module 8 typically includes a laser generator, optical fiber, galvanometer scanning system, and focusing lens. After the spring clip module is pressed, the galvanometer of the laser module 8 controls the laser beam to perform high-speed spot welding or seam welding on the contact area between the product surface and the spring clip along a preset path.

[0034] The carrier rotation module 9 is used to drive the first product carrier 23 and the second product carrier 24, along with the product, to rotate by a specific angle, typically 180°, after welding one side, to expose the next surface to be welded. It includes a first rotation drive unit 93, such as a servo motor-driven divider, and a clamp 91 driven by an eighth cylinder 92. When the carrier moves to the rotation station, the eighth cylinder 92 drives the clamp 91 to clamp the product carrier. Subsequently, the first rotation drive unit 93 drives the clamp 91 and the carrier to rotate precisely to the target angle of 180° before releasing them. This module achieves automatic rotation during the welding process, replacing the dangerous and inefficient manual rotation operation.

[0035] The pusher module 10 includes a pusher block mounted on a linear guide rail and a cylinder that drives the pusher block to move linearly. After the product completes the welding of its upper and lower surfaces on the first product carrier 23, the first carrier transfer module 2 moves it to the pusher station. The cylinder of the pusher module 10 is activated, driving the pusher block to move linearly and smoothly push the product out of the first product carrier 23.

[0036] The transfer module 11 receives products pushed out from the first workstation, adjusts their posture (typically rotating them 90°), and transfers them to the second product carrier 24. It includes a positioning carrier 111 driven by a second rotary drive unit 112, such as a servo motor, for receiving and rotating the product. The entire transfer module 11 is mounted on a linear slide driven by a rack and pinion transmission mechanism 113, allowing for overall movement and precise delivery of the rotated product into the second product carrier 24. The cooperation between the pusher module 10 and the transfer module 11 enables automatic product transfer and posture changes between two independent welding workstations, forming a key link in the continuous production line.

[0037] The unloading rotary module 13 is used to remove the finally welded product from the second product carrier 24 and place it onto the unloading conveyor line 1312. It includes a movable and rotatable gripper cylinder 1311. The drive unit, typically a combination of a servo module and a rotary cylinder, drives the gripper cylinder 1311 to move above the second product carrier 24, grip the product, rotate it at a certain angle to adjust the product's posture, and finally place it onto the unloading conveyor line 1312 for delivery.

[0038] To ensure process reliability and welding quality, the equipment is equipped with detection modules 14 at multiple key points. For example, fiber optic sensors are installed at the gripper positions of the spring sheet cutting and feeding module 6 to detect whether the spring sheet has been successfully gripped; fiber optic sensors are installed next to the first product carrier 23 and the second product carrier 24 to detect whether the product is placed in the correct position; sensors are installed at the pushing carrier 45 and the positioning carrier 111 of the transfer module 11 to confirm the product transfer status. All sensor signals are fed back to the central PLC control system in real time (not shown in the figure). The detection modules 14 form a closed loop for quality control, ensuring the reliability of each step.

[0039] The human-machine interface module 15 is typically an industrial touchscreen, mounted on the main body 1. Through this module, operators can set and store welding programs for different products, such as laser power, pulse time, welding path, adjust parameters of various servos and cylinders, monitor the real-time operating status of the equipment, signals of various sensors, production count, yield statistics, and receive graphic and text alarm information when a fault occurs.

[0040] The working principle and complete workflow of the automatic machine described in this invention are as follows: Phase 1: Product loading and welding of upper / lower surface spring clips, completed at the first welding station. 1. SFP28 optical module products are transported one by one and in an orderly manner to the end via the staggered feeding mechanism of feeding module 3.

[0041] 2. The suction cup 43 of the positioning and gripping module 4, in cooperation with the drive module 42 and the third cylinder 41, picks up the product, moves it horizontally and places it on the pusher carrier 45, and then the fourth cylinder 44 precisely pushes it into the first product carrier 23.

[0042] 3. The first carrier shifting module 2 drives the first product carrier 23 carrying the product to move to the upper surface welding station.

[0043] 4. The spring sheet cutting and feeding module 6 serving this station starts working: the servo feeding mechanism steps to convey the material belt, the cutting mechanism cuts out a single spring sheet, and then the gripper 64 of the precision transfer mechanism grabs the spring sheet and precisely positions it to the welding point on the upper surface of the product through the five-axis servo drive.

[0044] 5. The first spring clip module 7 operates to press the spring clip tightly.

[0045] 6. The laser module 8 moves above the workstation to perform laser welding on the pressed spring sheet.

[0046] 7. After welding is completed, the first carrier transfer module 2 drives the first product carrier 23 to move to the carrier rotation module 9. The clamp 91 clamps the carrier, and the first rotation drive unit 93 drives it to rotate 180° so that the lower surface of the product faces upward.

[0047] 8. The first carrier seat moving module 2 then moves the carrier seat to the lower surface welding station, and repeats steps 4-6 to complete the welding of the lower surface spring sheet.

[0048] Phase Two: Product Transfer and Side Spring Welding, the product is automatically transferred to the second welding station. 9. After completing the double-sided welding, the first carrier transfer module 2 moves the first product carrier 23 to the corresponding position of the pusher module 10.

[0049] 10. The pusher module 10 operates to push the product onto the positioning carrier 111 of the transfer module 11.

[0050] 11. The second rotation drive unit 112 of the transfer module 11 drives the positioning carrier 111 to rotate 90° so that the side to be welded faces upward. Then, the entire transfer module 11 moves linearly under the drive of the gear and rack transmission mechanism 113, and accurately inserts the rotated product into the second product carrier 24.

[0051] 12. The second carrier shifting module 21 drives the second product carrier 24 carrying the product to move to the side welding station.

[0052] 13. Another set of spring sheet cutting and feeding modules 6, second spring sheet pressing modules 12, and laser modules 8 working together at this station complete the spring sheet welding of one or two sides of the product. If welding of the other side is required, it can be rotated 90° by the carrier rotation module 9.

[0053] Phase 3: Finished Product Cutting 14. After all welding processes are completed, the second carrier transfer module 21 moves the second product carrier 24 to the unloading station.

[0054] 15. The gripper cylinder 1311 of the unloading rotary module 13 moves and grabs the product, rotates and adjusts its posture, and then places it on the unloading conveyor line 1312 to complete the entire automated process.

[0055] In summary, throughout the entire process, the detection module 14 monitors key steps in real time to ensure reliable operation, while the human-machine interface module 15 provides full-process monitoring and control. Two welding stations achieve automatic product flow and posture changes through material pushing and transfer, forming a continuous, closed automated production line. Through the integrated implementation of the above technical solutions, many problems associated with manual welding, such as low efficiency, poor precision, process interruptions, and safety hazards, are fundamentally solved, achieving efficient, high-quality, and fully automated production of the SFP28 optical module spring contact welding process.
