Description

TECHNICAL FIELD

[0001] The utility model relates to coupling equipment technical field, especially a kind of high-speed coupling equipment. BACKGROUND

[0002] High-speed coupling equipment is a key component in the fields of optical communication, radio frequency communication, semiconductor packaging and high-speed electronic devices, and its core function is to achieve efficient transmission and coupling of signals. With the rapid development of 5G communication, data center, Internet of Things and artificial intelligence technologies, the performance requirements of high-speed coupling equipment are increasingly improving, including higher transmission rates, lower signal loss, stronger anti-interference capability and more compact structural design. Through breakthroughs in precise mechanical adjustment, high-frequency electromagnetic optimization, circuit topology innovation and anti-interference packaging, the performance of high-speed coupling equipment is continuously improving, meeting the needs of high-speed, high-frequency and high-reliability scenarios, and will play an important role in more fields in the future, driven by intelligentization, integration and high-frequency technology.

[0003] Optical module high-speed coupling equipment is a core component in optical communication systems, used to achieve efficient optical signal transmission between lasers, optical fibers, photodetectors and other devices. Chinese Patent Publication No. CN222545537U discloses an optical fiber coupling device, which includes a base, a storage assembly, a coupling structure, and a handling assembly. The coupling station and the storage station are arranged along the length direction of the base. The storage assembly is arranged at the storage station and includes multiple coupling trays and stacking pieces. The coupling trays are used to fix optical fibers, mode strippers, and collimators, and the stacking pieces are used to automatically stack the coupling trays. The coupling structure is arranged at the coupling station and includes positioning tools, bare fiber adapters, and adjustment pieces. The positioning tools are used to fix the coupling trays, and the bare fiber adapters are used to fix one end of the optical fiber to output light to the optical fiber and the mode stripper. Through the arrangement of the related structures, the coupling positions of various materials during the optical fiber coupling process can be adjusted, and the automation degree is high. The coupling precision is fully guaranteed, and the efficiency is effectively improved. However, the device structure is complex, and the overall structure is adopted. Once a fault occurs, the maintenance difficulty is large, and a long downtime is required, which affects the production progress. Moreover, the material receiving plate of the comparative document does not have an adjustment mechanism, which may not be suitable for different sizes and thicknesses of substrates, limiting the use range of the device and reducing compatibility. In addition, the substrate positioning mechanism in the prior art may not be able to fine-tune the inclination angles in the X-axis and Y-axis directions, resulting in inaccurate positioning of the substrate during the coupling process and affecting the coupling quality. It may not be suitable for different sizes and thicknesses of substrates, limiting the use range of the device; and the existing coupling equipment uses a complex six-axis sliding table system, which needs to control the up-down, front-back, left-right axes and α, β, θ angle axes simultaneously.

[0057] As shown in the drawings, Figure 3 As shown, the substrate clamp 13 is provided with a main body portion 131, two recesses are formed in front and back of the main body portion 131, longitudinal guides 134 and sliders along the corresponding longitudinal guides 134 are arranged in the front recess 132 and the rear recess 133, a first spring 1361 is arranged between the front side wall of the front recess 132 and the front side slider 1351, and a second spring 1362 is arranged between the rear side wall of the rear recess 133 and the rear side slider 1352.

The limiting member 138 includes a longitudinally extending portion 1381 that penetrates into the channel 1311 and a vertically extending portion 1382 that extends downward from the end of the longitudinally extending portion 1381. The first support block is fixedly connected to the limiting member, thereby driving the limiting member to move. When the moving vertically extending portion 1382 can be blocked by the second movable seat below, excessive displacement is prevented, and the service life of the equipment is improved. Moreover, the design of the limiting member can not only make full use of the substrate clamp space through the channel position, but also cooperate with the first support block / second support block to move. A pull rod 139 is fixedly inserted inside the second support block, so that the operator can pull the pull rod 139 to drive the second support block 1372 to move back and forth. This allows the support block to be pulled back when it is necessary to loosen or place the substrate. After the substrate is placed, the pull rod can be released to complete the clamping.

[0059] like Figure 4 As shown, the coupling unit 2 includes: the stand 21, the coupling mechanism 22, the dispensing and UV curing mechanism 23, and the vision positioning mechanism 24. The stand 21 is equipped with the coupling mechanism 22, the dispensing and UV curing mechanism 23, and the vision positioning mechanism 24. The coupling mechanism 22 includes: a Z-axis linear module 221. The Z-axis linear module 221 is mounted on a rotary slide 223 via a first mounting base 222, and a suction nozzle fixture 224 for adsorbing devices to be coupled to the substrate is connected to the rotary slide 223.

The UV curing assembly 232 comprises a fourth driving cylinder 2321 obliquely mounted on the other side of the stand 21 and a second mounting base 2322 driven by the fourth driving cylinder 2321 to move obliquely up and down. The second mounting base 2322 is fixedly connected with a longitudinal mounting base 2323 located on one side of the substrate clamp 13. The longitudinal mounting base 2323 is mounted with two UV curing lamps 2324 symmetrically arranged front and back and obliquely downward toward the substrate clamp 13. In particular, the third driving cylinder is equipped with a micro-flow piezoelectric jet valve (glue amount control precision ±0.1 μL), and the glue dispensing head supports UV glue / epoxy resin multi-material switching. The UV curing lamp (wavelength 390 nm, irradiance ≥2000 mW / cm 2 ) integrates a temperature feedback system to prevent local overheating (temperature rise ≤3 ℃).

[0061] As shown in the drawings, the visual positioning mechanism 24 comprises: an R-axis rotary slide 241 obliquely mounted on one side of the stand 21 and a CCD camera 243 fixedly connected with the R-axis rotary slide 241 through a third mounting base 242 and toward the substrate clamp 13. The R-axis rotary slide 241 is longitudinally mounted on the inner wall of the side surface of the stand 21. In this way, the camera angle can be flexibly adjusted by adjusting the R-axis rotary slide 241. Specifically, the R-axis rotary slide can adopt a model RS60-L.

[0062] As described above, the device is adsorbed by the suction nozzle jig, and the space posture is adjusted by cooperating with the rotary slide. The glue dispensing assembly and the UV curing assembly of the device are symmetrically distributed on both sides of the stand to optimize the spatial layout. The glue dispensing assembly drives the glue dispensing head to move obliquely by the third driving cylinder to realize accurate glue coating. The UV curing assembly drives the second mounting base to move obliquely by the fourth driving cylinder to realize alignment of UV curing. Meanwhile, the longitudinal mounting base is fixed to the second mounting base and arranged with two UV curing lamps front and back symmetrically to expand the irradiation range, shorten the curing time and improve the UV curing efficiency. Meanwhile, the oblique mounting design optimizes the light path to improve the curing uniformity. The R-axis rotary slide of the visual positioning mechanism provides rotary motion for the CCD camera to realize multi-angle measurement and positioning. In this way, the coupling operation unit realizes high precision, high efficiency and high stability of the device coupling through the cooperative work of the Z-axis lifting, the rotary slide, the glue dispensing and UV curing mechanism and the visual positioning mechanism, which provides a reliable solution for automatic production.

[0063] The working process of the high-speed coupling device is as follows:

[0064] The substrate to be processed is placed in the substrate positioning unit, accurate positioning is realized through the dual-axis inclination adjusting mechanism and the XY-axis driving mechanism, and then the device to be coupled to the substrate is adsorbed through the suction nozzle jig; the device first performs a rough coupling operation to complete the preliminary alignment, and then determines the coupling effect through quality inspection, if it is unqualified, it prompts to recouple and adjust the position; after the rough coupling is qualified, the substrate is moved to the dispensing position by the XY-axis driving mechanism and the glue is coated through the dispensing assembly to provide a process basis for subsequent fine coupling; after dispensing is completed, fine coupling operation is performed, high-precision alignment of the device and the substrate is realized through the suction nozzle jig, and quality inspection is performed again to confirm the coupling precision; if the fine coupling is qualified, the UV curing assembly is started to irradiate the glue to make it solidify, the device is retracted after solidification is completed, and the coupled product is taken out, completing the entire automatic operation process.

[0065] In summary, in view of the problems of the existing high-speed coupling device, such as complex structure, high maintenance difficulty, poor compatibility, inaccurate positioning and mechanical precision decline, the scheme divides the device into a substrate positioning unit and a coupling operation unit through the upper and lower split modular design. The modules are independently operated and can be quickly disassembled and assembled, significantly reducing the maintenance difficulty, and the maintenance time is shortened from several hours of the traditional device to within 30 minutes, effectively reducing the downtime loss. The substrate positioning unit integrates the dual-axis inclination adjusting mechanism and the XY-axis driving mechanism, realizes accurate adjustment of the inclination angle of the X / Y axis through the micro-adjusting assembly of the circular surface fitting, cooperates with the high-precision linear module, and the positioning accuracy reaches the micron level, effectively solving the coupling deviation caused by the flatness error of the substrate. The substrate clamp adopts a detachable support block and a spring structure, supports the self-adaptive clamping of substrates of different thicknesses and sizes, and is adjusted manually to adapt to various specifications, and the compatibility is significantly enhanced. The coupling operation unit adopts symmetrical dispensing and UV curing assemblies, optimizes the light path design, expands the irradiation range, and significantly improves the curing efficiency, and integrates a temperature feedback system to avoid the deviation of the glue shrinkage rate caused by local overheating. At the same time, the linear motor is used to replace the traditional six-axis sliding table, reducing the mechanical gap and assembly error, and improving the repeat positioning accuracy. The visual positioning mechanism realizes multi-angle measurement through the rotating sliding table, improving the initial positioning accuracy. The overall scheme significantly improves the coupling efficiency and the reliability of the device through modular design, high-precision positioning, multi-specification compatibility and simplified mechanical structure, and provides an efficient and stable solution for high-speed optical communication, 5G communication and data center fields.
