Description

Technical Field

[0001] This utility model relates to the field of automation equipment technology, specifically to a LENS and jumper locking device. Background Technology

[0002] In the optoelectronic communication industry, high-speed optical modules using COB (Chip on Board) architecture require the simultaneous and precise connection of parallel 2, 4, 8, or even 16 LD (Laser Diode) optical signals into optical fibers, while simultaneously connecting the optical signals in the optical fibers into receiving PD (Photodiode). Lenses play a crucial role in this process, enabling the transmission of optical signals and achieving low-loss and stable connections. Finally, UV adhesive and curing adhesive are used to fix the lenses and other components in place.

[0003] Traditionally, lenses are manually placed into the clamps and then tightened with screws. This method has several drawbacks. First, manual lens placement is difficult and it's hard to ensure the lenses are placed flat, which affects the transmission of optical signals. Second, the jumper wires are in a free-insertion state and cannot be effectively secured. During later alignment operations, the jumper wires are prone to loosening and poor connection, severely impacting alignment efficiency. This increases instability in the production process and reduces product quality and consistency. Utility Model Content

[0004] The purpose of this utility model is to provide a LENS and jumper locking device to solve at least one of the above-mentioned technical problems.

[0005] This utility model achieves the above objectives through the following technical solutions: A LENS and jumper locking device includes: a gripper connecting angle, a LENS clamping cylinder, a jumper clamping cylinder, an MT jumper clamp, and a LENS clamp; The gripper connection angle is used to slide with the external Z-axis connection plate, so that the entire locking device can float along the Z-axis direction; The clamping jaw connecting angle is connected to the clamping LENS cylinder and the clamping jumper cylinder; The output end of the LENS clamping cylinder is connected to the LENS clamping jaw, and the output end of the jumper clamping cylinder is connected to the MT jumper clamping jaw. The LENS clamping cylinder drives the LENS clamping jaws to clamp the LENS, and the jumper clamping cylinder drives the MT jumper clamping jaws to clamp the MT jumper.

[0006] Furthermore, the locking device also includes: a linear slide rail and a slider; Multiple sliders are fixedly connected to the connecting angle of the gripper; The linear slide rail is longitudinally arranged on the Z-axis connecting plate; the size and position of the linear slide rail are matched with the slider, and the two are slidably connected.

[0007] Furthermore, the nominal width of the linear guide rail is 9 mm.

[0008] Furthermore, the locking device also includes: a claw distance adjustment block; The claw spacing adjustment block is used to adjust the width of the MT jumper jaws and the width of the LENS jaws.

[0009] Furthermore, the claw distance adjustment block is adjusted according to the size of the LENS.

[0010] Furthermore, the air circuits of the LENS clamping cylinder and the jumper cable clamping cylinder are connected in series with a delay valve, so that the MT jumper cable clamping jaws only perform the clamping action after the LENS clamping jaws have clamped.

[0011] The beneficial effects of this utility model are as follows: This invention features a simple operation process. Users only need to manually place the lenses into a multi-product compatible tray, and the device automatically completes the gripping and precise positioning. It supports simultaneous processing of single-channel transmitting / receiving lenses and multi-channel array lenses. Through a dual-cylinder linkage design, the lens-clamping cylinder first clamps the lens, and then, controlled by a delay valve, the jumper-clipping cylinder performs the clamping, ensuring stable connection between the jumper and the lens and effectively preventing loosening during later operations. Simultaneously, the jaw spacing adjustment block allows for flexible adjustment of the jaw width according to the lens size, further enhancing the adaptability to multiple product specifications. This invention significantly improves the stability of the production process and product consistency. Attached Figure Description

Detailed Implementation

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example 1 Figure 1 This is a schematic diagram of the overall structure of the LENS and jumper locking device according to one embodiment of the present invention; Figure 2 This is a side view of the LENS and jumper locking device according to one embodiment of the present invention. Figure 3 A front structural diagram of the LENS and jumper locking device according to one embodiment of this utility model. (See diagram below.) Figure 1-3 As shown, according to one embodiment of the present invention, a LENS and jumper locking device includes: a gripper connecting angle 303, a LENS clamping cylinder 304, a jumper clamping cylinder 305, a MT jumper clamping gripper 307, and a LENS clamping gripper 308. The gripper connection angle 303 is used for sliding connection with the external Z-axis connection plate 205, so that the entire locking device can float along the Z-axis direction; One side of the gripper connecting angle 303 is connected to a LENS clamping cylinder 304 and a jumper wire clamping cylinder 305; The output end of the LENS clamping cylinder 304 is connected to the LENS clamping jaw 308, and the output end of the jumper clamping cylinder 305 is connected to the MT jumper clamping jaw 307. The LENS 310 is clamped by the LENS clamping cylinder 304 driving the LENS clamping jaw 308, and the MT jumper clamping jaw 307 is clamped by the jumper clamping cylinder 305 driving the MT jumper clamping jaw 307.

[0016] Preferably, the air circuits of the LENS clamping cylinder 304 and the jumper cable clamping cylinder 305 are connected in series with a delay valve, so that the MT jumper cable clamping claw 307 performs the clamping action only after the LENS clamping claw 308 has clamped.

[0017] In this embodiment, a LENS and jumper cable locking device is proposed: the gripper connecting angle 303 slides with the external Z-axis connecting plate 205 through a slide rail-slider structure to form a suspended floating pair; if a collision occurs when the chuck descends to pick up the material, the gripper connecting angle 303 can slide upward relative to the Z-axis connecting plate 205 to absorb the overshoot in a purely mechanical way, protecting the LENS 310 and MT jumper cable 309 from rigid compression. The LENS clamping cylinder 304 and the jumper cable clamping cylinder 305 are fixed side by side on the same mounting surface of the gripper connecting angle 303, and the piston rod ends of the two cylinders drive the LENS clamping claw 308 and the MT jumper cable clamping claw 307 respectively; the air circuit has a built-in delay valve to ensure that the LENS clamping cylinder 304 acts first and clamps the lens, and then the jumper cable clamping cylinder 305 acts to press the jumper cable plug onto the lens tail, realizing "no loosening pre-locking" and providing a stable docking state for subsequent UV curing.

[0018] This invention uses a suspended floating pair to absorb the collision overshoot protection component, and the air delay valve achieves "no loosening pre-locking", providing a stable docking state for subsequent UV curing.

[0019] According to one embodiment of the present invention, the locking device further includes: a linear slide rail 301 and a slider 302; Multiple sliders 302 are fixedly connected to the gripper connecting angle 303; A linear slide rail 301 is longitudinally arranged on the Z-axis connecting plate 205; the size and position of the linear slide rail 301 are matched with the slider 302, and the two are slidably connected.

[0020] Preferably, the nominal width of the linear guide rail 301 is 9 mm.

[0021] In this embodiment, the locking device also includes a purely mechanical floating pair consisting of a linear slide rail 301 and a slider 302: several sliders 302 are fixedly mounted on the back of the gripper connecting angle 303, and the linear slide rail 301 is longitudinally fixed on the Z-axis connecting plate 205. The two slide together without an upper limit, so that the entire clamping unit is in a suspended state. During normal material handling, the chuck moves down synchronously with the Z-axis by its own weight. Once the LENS gripper 308 or the MT jumper gripper 307 touches the foreign object first, the reaction force pushes the gripper connecting angle 303 to move up along the linear slide rail 301 relative to the Z-axis connecting plate 205, instantly releasing the overshoot and avoiding hard collision. The upward movement is implicitly limited by the limit block or mechanical dead stop of the slide rail, without the need for sensors and additional return springs. The return is also completed by its own weight, thus giving the module passive safety protection capability while ensuring the sequential clamping function.

[0022] This invention utilizes a purely mechanical floating pair composed of a linear slide rail and a slider to automatically move upward and release overshoot upon collision, thus combining sequential clamping and passive safety protection functions.

[0023] According to one embodiment of the present invention, the locking device further includes: a claw distance adjusting block 306; The jaw gap adjustment block 306 is used to adjust the width of the MT jumper jaw 307 and the width of the LENS jaw 308.

[0024] Preferably, the claw distance adjustment block 306 is adjusted according to the size of the LENS 310.

[0025] In this embodiment, the locking device also includes a claw spacing adjustment block 306. The two claw spacing adjustment blocks 306 are respectively embedded in the root of the jaws of the LENS jaw 308 and the MT jumper jaw 307. The effective opening width of the two jaws can be changed through an adjustable rigid connection. When replacing LENS 310 with different outer diameters, the clamping envelope can be simultaneously reduced or enlarged by simply loosening or sliding the claw spacing adjustment block 306. This ensures that the clamping force is evenly distributed and the jumper plug can still accurately align with the lens end face. There is no need to completely replace the jaws, making the same floating locking module compatible with the mass production of multiple specifications of COB optical modules.

[0026] This invention achieves adjustable gripper width through a gripper distance adjustment block, which is compatible with multiple specifications of lenses and jumpers, improving adaptability for mass production.

[0027] Example 2 like Figure 1-3 As shown, according to one embodiment of this utility model, a LENS and jumper locking device uses an "automatic pick-and-place-lock" mechanism to simultaneously clamp, pre-align, and lock the LENS and MT jumper in the COB optical module, solving problems such as uneven placement, loose jumper connections, and loosening during later alignment in traditional manual methods. The locking device includes: a 9mm linear slide rail 301, a 9mm slider 302, a gripper connecting angle 303, a LENS clamping cylinder 304, a jumper clamping cylinder 305, a jaw distance adjusting block 306, an MT jumper gripper 307, and a LENS gripper 308. The linear guide rail 301 is longitudinally fixed to the Z-axis connecting plate 205. The slider 302 is sized to match the linear guide rail 301, and the two are slidably connected. The slider 302 is fixedly connected to the gripper connecting angle 303, which serves as the base platform for the locking device and is used to connect other components. By changing the position of the slider 302 on the linear guide rail 301, the locking device can float up and down relative to the Z-axis connecting plate 205.

[0028] The upper end of the gripper connecting angle 303 is locked to the slider 302, allowing it to slide up and down along the linear slide rail 301 (sliding down by its own weight and rebounding upon impact). Two cylinders are mounted side-by-side on the side of the gripper connecting angle 303 away from the slider 302: a LENS clamping cylinder 304 and a jumper wire clamping cylinder 305. The piston rods of the two cylinders are respectively fixed to the LENS clamping jaw 308 and the MT jumper wire clamping jaw 307. Driven by the LENS clamping cylinder 304 and the jumper wire clamping cylinder 305, the LENS clamping jaw 308 clamps the LENS 310, and the MT jumper wire clamping jaw 307 clamps the MT jumper wire 309. Each gripper is equipped with a jaw distance adjustment block 306. The width of the clamping jaw can be adjusted by rotating / sliding the jaw distance adjustment block 306, making the locking device compatible with different sizes of LENS 310 and MT jumper wire 309.

[0029] The LENS and jumper locking device of this utility model adopts a "gravity-floating" structure, and its working principle is as follows: The Z-axis is driven downward, and the Z-axis connecting plate 205 descends together with the linear slide rail 301. The gripper connecting angle 303 and the cylinder and gripper mounted on it descend synchronously by their own weight. When the grippers (including the MT jumper gripper 307 and the LENS gripper 308) reach the picking height, the cylinder actuates to complete the gripping. The LENS gripping cylinder 304 actuates first to confirm that the LENS 310 is clamped, and then the jumper gripper cylinder 305 actuates, inserting and locking the MT jumper 309.

[0030] If the position of LENS 310 or MT jumper 309 is abnormal or the material height is too high, the gripper will touch the surface of the part first. At this time, the gripper connecting angle 303 pushes down, while the chuck is subjected to an upward reaction force. When the reaction force is greater than the weight of the chuck, the gripper connecting angle 303 slides upward relative to the Z-axis connecting plate 205 along the linear slide rail 301. The collision energy is absorbed by the "relative displacement" and will not be pressed hard on the product or equipment.

[0031] This utility model's LENS and jumper locking device adopts a "gravity-floating" structure, which can simultaneously clamp, pre-align, and lock the LENS and MT jumper in one go, solving the problems of traditional manual operation. The chuck can slide up and down and can slide down under its own weight. In case of collision or interference, it can overcome gravity and slide upward to protect the product. It also has an adjustable gripper function to adapt to the handling of different products. The dual-clamp and clamping sequence design ensures stable clamping without any loose connections. Compared with traditional processes, it is more stable, improves production efficiency and product reliability, and reduces the defect rate.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
