Description

Technical Field

[0001] This invention relates to the technical field of optical fiber head processing equipment, specifically to a multi-station automatic grinding system and grinding processing method. Background Technology

[0002] After the fiber optic connector is processed, its end face often needs to be polished to ensure a smooth surface at the fiber end and improve the stability of signal transmission after the fiber connection. Currently, polishing typically involves first fixing the fiber optic connector to a plate using multiple pressure plates, then locking the pressure plates in place with screws. The plate is then placed on a polishing device and secured with screws or a fixing mechanism before polishing. Currently, to ensure stability after plate fixing and that the fiber end can act on the polishing plate, screws are commonly used, usually requiring four screws. When using a fixing mechanism, an eccentric rod rotation clamping method is generally used; this method is simple to operate but results in poor plate levelness after fixing. To address these issues, publication number CN202321837829.8 discloses a fiber optic connector polishing machine, including a machine body, a control panel on one side of the machine body, a mounting platform on the upper end of the machine body, a motor installed inside the machine body, and a polishing disc connected to the motor's output shaft. The polishing disc provided can be eccentrically mounted on the motor or coaxially mounted. The grinding disc is also covered with a cloth specifically designed for fiber optic grinding. It also features a fixing mechanism for securing the fiber optic head and a connecting mechanism for fixing the placement plate. Compared to existing technologies, this invention facilitates the grinding of the fiber end face on the fiber optic head and provides convenient fixation of the fiber optic head, as well as the ability to fix multiple fiber optic heads during grinding.

[0003] However, the aforementioned polishing machines still have the following problems: 1. Low automation efficiency; they can only perform polishing and cannot perform automatic cleaning. Cleaning can only be performed after replacing the machine with another one, affecting processing efficiency and failing to meet the needs of mass production of existing fiber optic heads; 2. Existing polishing machines require manual handling of the carrier and replacement of the polishing discs, resulting in high labor intensity, high costs, and machine downtime, affecting processing efficiency; 3. The mounting holes of existing carriers are mostly of fixed specifications and sizes, and cannot be automatically adjusted. They can only be used to fix fiber optic heads of one specification and size, resulting in low applicability. Customization and subsequent replacement are required, increasing costs and affecting efficiency. Summary of the Invention

The automatic adjustment structure of the placement hole is centered and corrected under the action of elastic force to ensure the placement position and vertical state of the fiber optic head.

[0021] Step 2 Material feeding and coarse grinding: The tray is placed on the conveying and distributing device.

The platform moves backward, and the first conveying mechanism moves the tray to the first displacement mechanism.

[0023] Grinding disc processing: After the grinding machine finishes processing, the transport robot will transport the grinding disc to the cleaning device for cleaning; when the grinding disc has been used a set number of times, the transport robot will transport the grinding disc to the grinding disc waste recycling component, and then take a new grinding disc from the grinding disc placement bracket for replacement;

[0024] Step 4: Second fine grinding and grinding disc processing: The first conveying mechanism operates to transport the tray after the first fine grinding to the second cleaning mechanism for cleaning. After cleaning, the second conveying mechanism operates, and the first pushing mechanism on the second conveying mechanism transports the tray to the platform of the third displacement mechanism.

[0031] The beneficial effects of this invention are as follows: 1. This invention achieves fully automated processing of optical fiber head material tray handling, sorting, cleaning, grinding, unloading, and product and tray recycling by setting up a conveyor and material distribution device, a coarse grinding device, a multi-station grinding device, a handling device, and a conveyor belt assembly. This reduces manual labor intensity and improves production efficiency. Furthermore, by setting up a cleaning mechanism to clean the ground optical fiber head material, it prevents the hardening of impurities due to untimely processing after grinding, which would reduce the efficiency and quality of subsequent fine grinding. This ensures the quality of grinding processing and meets the needs of existing mass production of optical fiber heads.

[0032] 2. A multi-station grinding device, consisting of multiple grinding units, is used to perform multiple fine grinding processes on the fiber optic head. This ensures both the processing efficiency of the grinding device and the service life of the grinding discs. Furthermore, if one grinding unit malfunctions, the others can continue operating, ensuring stable grinding processing. A transport mechanism combined with two pushing mechanisms is used for transporting the tray, achieving synchronous transport actions and significantly improving transport efficiency and coordination, thereby increasing grinding processing efficiency. A robotic arm is used for transporting and replacing the grinding discs, greatly reducing manual labor intensity and costs, and enabling automated operation without machine downtime, ensuring processing efficiency. A second clamp is used for flipping the grinding discs, combined with a cleaning device, improving cleaning efficiency and effectiveness, preventing incomplete cleaning that could lead to decreased grinding precision or quality, and extending the service life and quality of the grinding discs.

[0033] 3. By setting an automatic adjustment structure composed of multiple spring plates, the spring plates are arranged in a circular array on the inner wall of the placement hole, and the spring plates gradually tilt from top to bottom towards the center of the circle. The automatic adjustment structure is used to automatically adjust the specifications of the placement hole, so that the placement hole can be used to fix fiber optic heads of different specifications and sizes, improve applicability, and ensure the placement position and verticality of the fiber optic heads, thereby ensuring the subsequent polishing quality and effect.

This reduces manual labor intensity and improves production efficiency. Furthermore, a cleaning mechanism is included to clean the ground optical fiber head material, preventing impurities from hardening and reducing the efficiency and quality of subsequent fine grinding due to delayed post-grinding treatment, thus ensuring grinding quality and meeting the needs of mass production of optical fiber heads. A multi-station grinding device, consisting of multiple grinding units, performs multiple fine grinding processes on the optical fiber head, ensuring both processing efficiency and the lifespan of the grinding discs. If one grinding unit malfunctions, the others can continue operating, ensuring stable grinding processing. A handling mechanism combined with two pushing mechanisms for tray handling further enhances the efficiency of the process. The synchronous handling action greatly improves handling efficiency and coordination, thereby increasing the efficiency of the grinding process. By using a robotic arm for handling and replacing grinding discs, manual labor intensity and costs are significantly reduced, and automated operation is possible without machine downtime, ensuring processing efficiency. A second clamp is used to flip the grinding discs, combined with a cleaning device to improve cleaning efficiency and effectiveness, preventing incomplete cleaning that could lead to decreased grinding precision or quality, and extending the lifespan and quality of the grinding discs. An automatic adjustment structure composed of multiple spring plates arranged in a circular array on the inner wall of the placement hole, with the spring plates gradually tilting towards the center from top to bottom, automatically adjusts the size of the placement hole. This allows the hole to be used to fix fiber optic heads of different sizes, improving applicability and ensuring the placement position and verticality of the fiber optic heads, thus guaranteeing the subsequent grinding quality and effect.
