Description

Technical Field

[0001] This utility model relates to the field of optical module detection technology, and more specifically, to an optical module press-to-unlock device. Background Technology

[0002] An optical module is an optoelectronic device that performs photoelectric and electro-optical conversion. The transmitting end of the optical module converts electrical signals into optical signals, and the receiving end converts optical signals back into electrical signals. After production, optical modules need to be sent to testing equipment for inspection. During testing, the optical fiber must be connected to the optical module, and after testing, the optical module must be unlocked and separated from the optical fiber. Current optical module unlocking is performed using an unlocking device, which typically employs two sets of cylinders. One set of cylinders controls the horizontal movement of the entire unlocking device, while the other set of cylinders drives the lifting and lowering of a pressing rod. The pressing rod then touches the unlocking plate on the top of the optical module, thus unlocking the optical module from the optical fiber. However, when testing multiple optical modules simultaneously, and given the presence of multiple fiber optic cables on the testing equipment, the excessive range of motion of the two sets of cylinders can easily touch and pull on the fiber optic cables, potentially damaging the testing equipment.

In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0022] Please refer to Figures 1 to 5 This utility model provides a light module press-to-unlock device, including a base 1, a cylinder seat 2, a rotary cylinder 3, and a pressing rod 4; the cylinder seat 2 is installed on the top of the base 1, the rotary cylinder 3 is installed on the cylinder seat 2, and the piston rod of the rotary cylinder 3 is connected to the pressing rod 4; the top of the rotary cylinder 3 is provided with two diagonally opposite positions of limiting rods 5, and the pressing rod 4 is located between the two limiting rods 5.

[0023] In this embodiment of the invention, the base 1 serves to install the entire unlocking device into the optical module's detection equipment. The cylinder seat 2, as the connecting component between the base 1 and the rotary cylinder 3, optimizes the positional layout of the rotary cylinder 3, making the air pipe distribution of the rotary cylinder 3 more reasonable and reducing interference with surrounding equipment. The rotary cylinder 3 acts as a power source; when it receives a control signal, its internal piston moves linearly under air pressure, transmitting power to the pressing rod 4 via the piston rod. The pressing rod 4, driven by the piston rod, performs rotational and downward movements. To avoid damage to the optical module or failure of the unlocking function due to excessive rotation caused by air pressure or cylinder malfunction, this embodiment sets up a pair of limiting rods 5 and places the pressing rod 4 between the two limiting rods 5. The limiting rods 5 restrict the movement trajectory of the pressing rod 4, so that it can only reciprocate within a specific direction and range. This ensures that the pressing rod 4 can accurately press on the unlocking part of the optical module to realize the pressing unlocking action, prevents the pressing rod 4 from excessively moving and causing damage to the optical module or other components, and ensures the safety and stability of the device operation.

[0024] The working process of this embodiment is as follows: Rotary cylinder 3 is in the initial position, at which point the pressing lever 4 is away from the optical module to be pressed. When the control system sends a drive signal, rotary cylinder 3 begins to work. Compressed air supplied by the air source enters rotary cylinder 3, pushing the piston to move. The piston rod drives the pressing lever 4 to rotate at a certain angle before pressing. After reaching the predetermined pressing position, the pressing lever 4 maintains its pressing state on the unlocking component of the optical module until the optical module separates from the optical fiber. Afterwards, the control system sends a signal to cause rotary cylinder 3 to reverse its movement, retracting the pressing lever 4 and returning it to its initial position, ready for the next cycle.

[0025] Preferably, the pressing rod 4 has an L-shaped cross-section, including a long side 41 and a short side 42. One end of the long side 41 is connected to the piston rod of the rotary cylinder 3, and a pressing block 43 is provided at the bottom of one end of the short side 42.

[0026] Preferably, grooves 411 are provided on both sides of the long side 41, and a pad 412 is provided on the groove 411. The pad 412 is configured to cooperate with the limiting rod 5. In this embodiment, the grooves 411 facilitate the installation and replacement of the pad 412. If the pad 412 is worn or damaged, it can be simply removed from the groove 411 for replacement, which is simple and convenient. In addition, by adjusting the position of the pad 412 in the groove 411 or by replacing the pad 412 with one of different thicknesses, the movement range and position of the pressing rod 4 can be finely adjusted to adapt to the unlocking requirements of different optical modules.

[0027] Preferably, the pressing block 43 and the pressing rod 4 are detachably connected, and the bottom of the pressing block 43 is provided with multiple pressing contacts. In this embodiment, the pressing block 43 may experience wear and damage after long-term use. The detachable connection allows the pressing block 43 to be easily removed from the pressing rod 4 and replaced with a new pressing block 43 without replacing the entire pressing rod 4, reducing maintenance costs and difficulty. In addition, different types or specifications of optical modules may require pressing blocks 43 of different shapes, sizes, or materials to achieve the best unlocking effect. Through the detachable connection, a suitable pressing block 43 can be quickly replaced according to actual needs, improving the versatility and flexibility of the pressing unlocking device.

[0028] Preferably, the bottom of the limiting rod 5 is provided with a threaded portion, and the threaded portion is threadedly connected to the rotary cylinder 3. The threaded connection method does not require additional connecting parts or complex installation structures, and can make the structure of the entire device more compact while ensuring connection strength.

[0029] Preferably, the base 1 includes a base plate 11, a top plate 12, and a support plate 13. The base plate 11 has an L-shaped structure, with a mounting groove 111 at one end and the other end connected to the top plate 12. The top plate 12 has a positioning groove 121 that mates with the top of the base plate 11, and the positioning groove 121 overlaps with the base plate 11. The support plate 13 has a triangular structure, with one side connected to the base plate 11 and the other side connected to the top plate 12. In this embodiment, the triangular support plate 13 provides stable support for the base 1, ensuring the stability of the entire optical module press-to-unlock device and preventing it from shaking or tipping over due to external forces during operation. The mounting groove 111 at one end of the L-shaped base plate 11 can be used to install other related components, such as an optical module detection system, or to connect to external equipment, facilitating the integration and installation of the overall device. Simultaneously, this shape design better adapts to different spatial environments, achieving functional diversity within a limited space. The positioning groove 121 on the top plate 12 mates with the top of the bottom plate 11, making the connection between the bottom plate 11 and the top plate 12 more precise and stable. During installation, it can quickly guide the bottom plate 11 and the top plate 12 to align, improving installation efficiency. The bottom plate 11, top plate 12, and support plate 13 are interconnected to form an integral frame structure. This combination enhances the overall structural strength of the base 1. It can withstand the reaction force generated by the pressing rod 4 during operation and other possible external impacts, ensuring the reliability and durability of the device.

[0030] Preferably, the cylinder seat 2 is provided with a set of adjustable mounting slots 21, and bolts are installed on the slots 21 and connected to the top plate 12 by the bolts. The design of the slots 21 allows the connection position between the cylinder seat 2 and the top plate 12 to be adjusted within a certain range. During installation, if it is necessary to fine-tune the position of the rotary cylinder 3 according to the specific position of the optical module or the layout of other components, simply loosen the bolts, move the cylinder seat 2 along the slots 21 to the appropriate position, and then tighten the bolts. There is no need to redesign or modify the installation structure, which greatly improves the flexibility and convenience of installation.

[0031] Preferably, a proximity switch is provided below the pressing rod 4, which is used to detect whether the pressing rod 4 has reached the predetermined position. By detecting the position of the pressing rod 4, it is possible to prevent the pressing rod 4 from exceeding the normal range of motion, thus protecting the pressing rod 4 itself, the optical module, and other related equipment. This avoids damage to components caused by excessive movement of the pressing rod 4 due to misoperation or equipment malfunction, reducing equipment maintenance costs and extending equipment lifespan. In addition, during the equipment debugging phase, the proximity switch helps operators accurately determine whether the position of the pressing rod 4 meets the requirements, facilitating the adjustment and optimization of the pressing rod 4's stroke. During equipment operation, if an unlocking abnormality occurs, the feedback information from the proximity switch can quickly determine whether the problem lies in the position control of the pressing rod 4, facilitating troubleshooting and repair by maintenance personnel and improving equipment maintainability.

[0032] Compared with existing technologies, the advantages of this invention are as follows: This invention uses a rotary cylinder as a power source. When the optical module approaches, the rotary cylinder transmits power to the pressing rod through the piston rod, enabling the pressing rod to accurately press on the unlocking part of the optical module, thus achieving the press-to-unlock action. Simultaneously, a limit rod is set to limit the stroke of the pressing rod, preventing excessive movement and damage to the optical module. The overall structure of this invention is relatively simple and compact, enabling the press-to-unlock function of the optical module within a limited space. It is suitable for equipment or automated systems with stringent space requirements, avoiding potential collisions or interference problems that may occur during unlocking. Installation and maintenance are convenient, reducing equipment costs and facilitating widespread adoption and use.
