Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of optical fiber head production, more particularly, the present application relates to an optical fiber head grinder. BACKGROUND

[0002] The optical fiber head grinder is an indispensable precision machining equipment in the field of optical communication, which is specially used for high-precision grinding and polishing of the ceramic ferrule end face of the optical fiber connector. Through the stepped grinding process, it can polish the optical fiber end face to nanometer flatness, significantly reduce the insertion loss during optical signal transmission, and ensure the connection stability and transmission efficiency. With the improvement of the quality requirements of 5G, data center and other optical fibers, the optical fiber head grinder has become a key tool to ensure the reliability of high-speed network.

[0003] In the traditional optical fiber head grinding production mode, the key processes such as feeding and discharging, grinding, intermediate cleaning, final cleaning and waste recycling are usually completed by multiple independent and dispersed devices respectively. This highly dispersed layout forces the production personnel to repeatedly take, place and transfer the workpieces between different stations, which not only significantly prolongs the overall operation cycle, resulting in low production efficiency, but also greatly increases the risk of pollutants such as dust and fingerprints adhering to the precision optical fiber end face in the process of frequent manual intervention. At the same time, due to the lack of unified automatic process control, the connection between processes is not coherent enough, which is easy to cause production rhythm disorder, product quality fluctuation, even batch damage, and seriously restricts the improvement of production efficiency and product yield.

[0004] In summary, in order to improve the optical fiber head grinding efficiency, it is necessary to solve the problem of serious dispersion of traditional optical fiber head grinding process, which leads to low production efficiency, even causes batch damage, and seriously restricts the improvement of production efficiency and product yield, so that the optical fiber head grinder can meet all the processes of optical fiber head grinding at the same time.

[0037] It is worth noting that material plate 2 is used to carry material disc, and the material disc is neatly arranged with optical fiber heads that have completed ferrule crimping and are waiting for grinding, then the full material disc is sent in through feeding conveyor belt 3, and the finished product material disc that has completed all processing procedures is sent out through discharging conveyor belt 4, first suction cup 7 on triangular plate 6 is used to adsorb sandpaper, claw hand 11 is used to grab material disc, L-shaped clamp 9 is used to clamp glue disc, the clamped glue disc is placed on grinding table 1201 of grinding machine body 12, sandpaper is adhered on glue disc, material disc is installed on mounting arm 1202, and grinding machine body 12 controls it to move in "8" shape or elliptical trajectory, and the optical fiber end face is ground and polished, in the grinding process, liquid spray nozzle 15 continuously sprays grinding coolant (such as alcohol) to the grinding area, and used grinding liquid and grinding dust are collected and discharged through liquid discharge pipeline 16, to keep the workbench clean.

[0038] Referring to the drawings Figure 4 The clamping assembly comprises a first sliding rail 801 fixedly connected to the triangular plate 6, a first bidirectional air cylinder 802 fixedly connected to the first sliding rail 801, and two first sliding blocks 803 symmetrically fixedly connected to the output end of the first bidirectional air cylinder 802, wherein the first sliding blocks 803 are in sliding connection with the first sliding rail 801, and the first bidirectional air cylinder 802 is used to drive the two first sliding blocks 803 to move towards or away from each other along the first bidirectional air cylinder 802.

[0039] It should be noted that the piston rods of the first bidirectional air cylinder 802 can be extended at both ends, and when compressed air is supplied, the two piston rods (output end) can be synchronously driven to move linearly towards or away from each other, thereby realizing the simultaneous and equidistant approach or departure of the two L-shaped clamping plates 9, and simultaneously ensuring the linearity and stability of the movement of the first sliding blocks 803 by the first sliding rail 801, thereby preventing shaking or deviation.

[0040] Referring to the drawings Figure 8 And Figure 9 The cleaning workbench 103 is provided with two switch assemblies, the output end of the switch assembly is connected with a sliding door plate 18, the sliding door plate 18 is in sliding connection with the cleaning workbench 103, the switch assembly is used to drive the sliding door plate 18 to move in a predetermined direction, the cleaning workbench 103 is provided with two transfer assemblies, the output end of the transfer assembly is connected with a third one-way air cylinder 20, the transfer assembly is used to drive the third one-way air cylinder 20 to move in a predetermined direction, the output end of the third one-way air cylinder 20 is fixedly connected with a second sliding plate 21, the third one-way air cylinder 20 is used to drive the second sliding plate 21 to move in a vertical direction, the second sliding plate 21 is fixedly connected with a loading platform 22, the cleaning workbench 103 is fixedly connected with two cleaning tanks 23, the cleaning tank 23 is fixedly connected with a liquid level sensor 24, and the cleaning tank 23 is fixedly connected with a liquid conveying pipeline 27.

[0041] It should be noted that the sliding door plate 18 serves as an automatic door of the sealed cleaning cavity of the cleaning workbench 103, and is designed as a translation type, which is closed in a non-working state to prevent pollutants in the external air from entering the cleaning area, and is closed during the cleaning process to form a sealed space, thereby preventing the escape of cleaning liquid vapor and ensuring that the cleaning process is not disturbed.

[0042] It is worth noting that the object table 22 can be placed on the tray to clean the optical fiber head, and can also be placed on the polished glue disc and sandpaper to flush off the polishing residue. At the same time, the liquid level sensor 24 is used to monitor and control the liquid level of the cleaning liquid in real time. The liquid level sensor 24 adopts a float type liquid level meter. The liquid level change is sensed by the rise and fall of the internal magnetic float. When the liquid level in the cleaning tank 23 drops to the lowest set point, the float drops and drives the internal dry reed tube to attract, sending a "low liquid level" electrical signal. After the control system receives this signal, it will immediately command the electromagnetic valve or liquid pump connected with the liquid pipeline 27 to start, and supplement the cleaning liquid in the tank. With the rise of the liquid level, the float also rises. When it reaches the highest set point, the float makes the dry reed tube disconnected, and the signal disappears. The control system stops supplying and stops adding liquid. This cycle realizes the automatic maintenance and accurate control of the cleaning liquid level.

The side plate 31 is provided with a feeding roller 3101, a receiving roller 3103 and a plurality of unpowered rollers 3102, the side plate 31 is fixedly connected with a fifth one-way air cylinder 32, the output end of the fifth one-way air cylinder 32 is fixedly connected with a pressing plate 33, and the fifth one-way air cylinder 32 is used to drive the pressing plate 33 to move in the vertical direction.

[0050] It should be noted that the feeding roller 3101 is used to carry and release the non-woven fabric in roll, the receiving roller 3103 is used to roll up the used and contaminated non-woven fabric, the unpowered roller 3102 plays a guiding and tensioning role, ensures that the non-woven fabric is flat and moderately tensioned on the path from the feeding roller 3101 to the receiving roller 3103, and avoids wrinkles or slack.
