Description

Technical Field

[0001] This invention relates to the field of optical cable junction box processing technology, and in particular to an automatic assembly device for optical cable junction box bodies. Background Technology

[0002] An optical fiber junction box is a connection device that provides termination and patching for backbone optical cables and distribution layer optical cables. After the optical cable is introduced into the junction box, it is fixed, terminated, and distributed. Then, patch cords are used to connect the backbone optical cable and the distribution layer optical cable. Since the optical fiber junction box is installed outdoors, its most fundamental requirement is to withstand drastic climate changes and harsh working environments. It must be waterproof, dustproof, insect and rodent resistant, and highly impact-resistant. Therefore, the exterior of the box has high requirements for waterproofing, moisture resistance, dustproofing, impact resistance, and insect and rodent protection; the interior requires very strict temperature and humidity control.

[0003] Optical cable junction boxes are increasingly being produced using automated production lines. The junction box panels are drilled and slotted automatically to accommodate subsequent assembly and fixing of supporting panels, fiber optic trays, and other structures. However, during the automated assembly of the fiber optic trays inside the semi-finished junction boxes, the drilling process on the panel surface results in residual burrs and sharp protrusions in the hole and slot areas. This causes scratches and damage to the surface of the fiber optic trays in contact with the panels, and the sharp protrusions also affect the assembly of the fiber optic trays with the panel holes and slots. In the existing automated assembly process, the panel is easily affected by transportation friction and other external factors, causing misalignment between the panel and the fiber optic tray to be assembled. This leads to misalignment of the holes and slots, which can cause screws to pierce the fiber optic trays along the misaligned holes and slots when tightening, affecting yield and cost.

[0004] To address the aforementioned technical shortcomings, a solution is proposed. Summary of the Invention

[0005] The purpose of this invention is to provide an automatic assembly device for optical cable junction boxes, addressing the problem that existing optical cable junction boxes are increasingly being produced using automated production lines. While the junction box panels are automatically drilled and slotted to accommodate subsequent assembly and fixing of supporting panels, fiber optic trays, and other structures, during the automated assembly of the fiber optic trays within the semi-finished junction box, burrs and sharp protrusions remain in the hole and slot areas after drilling. This causes scratches and damage to the surface of the fiber optic trays in contact with the panels, and the sharp protrusions hinder the assembly of the fiber optic trays with the panel holes and slots. Furthermore, in existing automated assembly processes, the panels are easily affected by transportation friction and other external factors, leading to misalignment between the panels and the fiber optic trays to be assembled. This misalignment of the holes and slots causes screws to pierce the fiber optic trays along the misaligned holes and slots during tightening, affecting yield and cost.

[0016] The operating method of the automatic assembly device for optical cable junction boxes includes the following steps:

[0017] Step 1: The transfer box is moved along the conveyor roller to the conveyor frame. The second connecting rod rotates with the output end of the servo motor. The first connecting rod drives the guide rod with the second connecting rod. The guide rod is pulled and slides down in a counterclockwise 90-degree trajectory. At the same time, the other end of the sliding rod slides back and forth along the inside of the rotating sleeve, and drives the rotating sleeve to rotate clockwise 90 degrees along the first transmission shaft. One end of the sliding rod moves closer to the conveyor roller with the transmission of the guide rod. When the limit frame and the transfer box on the conveyor roller are horizontal, the first linear cylinder drives the first suction cup to approach and adsorb the sealing area on the back of the transfer box. The second connecting rod moves in a circular motion with the output end of the servo motor. The first connecting rod drives the guide rod to slide up and reset.

[0018] Step 2: During the process of the transfer box being lifted and picked up by adsorption, when the horizontal center line of the transfer box forms a 45-degree angle with the conveyor roller, the servo motor stops, the cleaning sliding frame slides along the inclined groove, the sliding seat drives the electric push rod to slide and adjust along the surface of the sliding frame, the electric push rod moves the grinding disc close to the inside of the transfer box, the rotary motor drives the grinding disc to rotate, and performs friction cleaning on the surface of the holes and grooves inside the transfer box. When the cleaning is completed, the electric push rod resets, and the guide rod drives the transfer box to rotate 90 degrees and face the guide plate through the limit frame, forming a 90-degree rotating adsorption and picking structure;

[0019] Step 3: The fiber melting tray assembled by the feeding conveyor belt is placed onto the feeding support frame. The slider moves along the sliding frame, driving the guide plate to move above the fiber melting tray. The lifting cylinder's movable rod drives the beam plate to slide down the slide rail. The linkage slides down the straight groove area at the bottom of the irregular groove, causing the second suction cup on the second linear cylinder to adsorb the fiber melting tray. The slider drives the guide plate to move to the middle of the sliding frame. The positioning light-emitting plate illuminates the light source according to the partial holes and slots inside the junction box. The laser alignment sensor aligns with the light source holes and slots inside the junction box along with the guide plate, and the laser alignment sensor collects the light source penetrating the holes and slots to assist the guide plate. Lateral fine-tuning is performed along the sliding frame. The small cylinder drives the lifting cylinder to slide up the slider to adjust the guide plate to be vertically aligned with the slot. The lifting cylinder's movable rod drives the beam rod to slide up the slide rail. The linkage moves up with the beam rod and slides along the irregular groove. The linkage drives the second linear cylinder to rotate 90 degrees clockwise through the shaft. The second linear cylinder drives the fiber melting plate to be aligned with the slot. Based on the data collected by the laser alignment sensor, the rotary cylinder is started. The rotary cylinder adjusts the turntable. The fiber melting plate rotates with the turntable to fine-tune its alignment with the slot. The second linear cylinder drives the second suction cup to move laterally closer to the slot inside the junction box.

[0020] Step 4: The cylinder on the locking sliding frame drives the screw-operated robotic arm to approach the exposed slots on the back of the transfer box. The slots of the transfer box frame and the fiber melting tray are fixed with screws one by one. The servo motor drives the guide rod to slide down and rotate 90 degrees, placing the transfer box onto the conveyor roller and adsorbing and picking up the next set of transfer boxes. During the downward placement of the transfer box, the debris remaining inside the transfer box slides down the door of the transfer box onto the screen, and the debris is collected in the waste box along the screen.

[0021] The beneficial effects of this invention are:

[0022] (1) The present invention uses a servo motor to drive the slide bar and guide rod to adjust the rotation of the limiting frame. The limiting frame moves back and forth along the 90-degree trajectory of the second transmission shaft. With the help of the first suction cup, the adsorption and picking structure can be flipped 90 degrees, which facilitates the independent adsorption gripping and positioning of a single set of transfer boxes, and assists the subsequent fusion fiber trays in calibration and docking assembly. The gripped transfer box is temporarily fixed at a 45-degree angle by flipping the adsorption and picking structure. The cleaning sliding frame is used to adjust the grinding disc to extend into the transfer box for friction cleaning of the hole groove surface. The tilted and fixed transfer box avoids the debris generated by friction cleaning from entering the hole groove and promotes the debris to fall off, preventing the debris from affecting the subsequent fusion fiber tray installation.

[0023] (2) By using the laser centering sensor and the positioning light-emitting plate in combination, the light source penetration centering calibration and positioning of the hole slot is performed. The guide plate is finely adjusted vertically and horizontally using a small cylinder and slider. The second linear cylinder is rotated 90 degrees to align the irregular groove auxiliary beam plate. The second suction cup is assisted by a rotary cylinder to adjust the angle of the clamped fiber melting tray. This causes the clamped fiber melting tray to be finely adjusted multiple times to align with the hole slot, thus realizing the temporary flexible calibration docking assembly of the clamped junction box and the clamped fiber melting tray.

[0039] This embodiment addresses the problem of residual burrs and sharp protrusions in the local hole and groove areas caused by the hole-making process on the box panel, resulting in scratch damage to the surface of the fiber optic tray in contact with the box panel, and the problem of sharp protrusions affecting the assembly of the fiber optic tray and the hole and groove of the box panel.

[0040] Please see Figures 1-6 As shown, this embodiment is an automatic assembly device for optical cable junction boxes, including a conveyor frame 1.

A second connecting rod 414 is sleeved at the output end of the servo motor 406, and a first connecting rod 413 that is sleeved with the guide rod 405 is rotatably connected at the other end of the second connecting rod 414. A sloping groove 407 that is recessed into the surface of the flipping material handling frame 4 and slidably connected to the cleaning sliding frame 3 is provided on the side of the servo motor 406.

[0042] A rotating sliding sleeve 402 is fitted on the middle of one end of the slide rod 403, and the other end of the slide rod 403 is rotatably connected to the top of the guide rod 405. A first transmission shaft 401 is provided on the top of one end of the flipping material picker 4 and is rotatably connected to the rotating sliding sleeve 402.

[0043] The bottom of the guide rod 405 is rotatably connected to the second drive shaft 404, which is connected to the side wall of the flipping material picker 4. The middle part of the guide rod 405 is provided with a protrusion 412 connected to the first connecting rod 413. A rotating block 408 is sleeved on the top side of the guide rod 405, and the axis of the rotating block 408 passes through the guide rod 405 and is engaged with the other end of the slide rod 403.

[0046] Example 2:

[0047] This embodiment addresses the problem that in existing automated assembly processes, the box panel is easily affected by transportation friction and other external factors, causing misalignment between the box panel and the fiber optic tray to be assembled. This misalignment of the holes and slots leads to screws piercing the fiber optic tray along the misaligned holes and slots when tightened, affecting yield and cost.

[0053] Combining Embodiments 1 and 2, the sliding rod and guide rod assist in the flipping and picking structure to form a 90-degree flipping adsorption and picking structure. During the flipping process, it can be paused and used in conjunction with the cleaning sliding frame to perform inclined friction cleaning on the surface of the slots inside the transfer box, preventing debris generated during friction cleaning from entering the slots and promoting the falling off of debris to prevent debris from affecting the subsequent installation of the fiber fusion tray. At the same time, the slots can be used for light source penetration, centering, calibration, and positioning, enabling temporary and flexible calibration, docking, and assembly of the clamped transfer box and the clamped fiber fusion tray.

[0054] like Figures 1-11 As shown, the working method of the automatic assembly device for the optical cable junction box includes the following steps:

[0055] Step 1: In use, the transfer box is moved along the conveyor roller 101 to the conveyor frame 1. The servo motor 406 is started, and the second connecting rod 414 rotates with the output end of the servo motor 406. The first connecting rod 413 drives the guide rod 405 with the second connecting rod 414. The guide rod 405 is pulled down in a counterclockwise 90-degree trajectory. At the same time, the other end of the sliding rod 403 slides back and forth along the inside of the rotating sleeve 402, and drives the rotating sleeve 402 to rotate clockwise 90 degrees along the first transmission shaft 401. One end of the sliding rod 403 moves closer to the conveyor roller 101 with the guide rod 405. When the limit frame 410 is horizontal with the transfer box on the conveyor roller 101, the first linear cylinder 409 drives the first suction cup 411 to approach and adsorb the sealing area on the back of the transfer box. The second connecting rod 414 moves in a circular motion with the output end of the servo motor 406. The first connecting rod 413 drives the guide rod 405 to slide up and reset, completing the positioning, adsorption, material picking and lifting of the transfer box.

[0056] Step 2: During the process of the transfer box being adsorbed and lifted, when the horizontal center line of the transfer box forms a 45-degree angle with the conveyor roller 101, the servo motor 406 stops, the cleaning sliding frame 3 slides along the inclined groove 407, the sliding seat 302 drives the electric push rod 304 to slide and adjust along the surface of the sliding frame, the moving rod of the electric push rod 304 drives the grinding disc 303 to approach the inside of the transfer box, the rotary motor 305 drives the grinding disc 303 to rotate, and performs friction cleaning on the surface of the holes and grooves inside the transfer box. When the cleaning is completed, the electric push rod 304 resets, the servo motor 406 starts, the guide rod 405 drives the transfer box to rotate 90 degrees through the limit frame 410 and face the guide plate 205, forming a 90-degree rotating adsorption and material picking structure;

[0057] Step 3: The fiber melting tray assembled by the feeding conveyor belt 201 is placed onto the feeding support frame 2. The slider 203 moves along the sliding frame 202, driving the guide plate 205 to move above the fiber melting tray. The lifting cylinder 204's movable rod drives the beam plate 209 to slide down along the slide rail 206. The linkage 213 slides down along the bottom straight groove area of ​​the irregular groove 207, causing the second suction cup 211 on the second linear cylinder 210 to adsorb the fiber melting tray. The slider 203 drives the guide plate 205 to move to the middle of the sliding frame 202. The positioning light-emitting plate 5 is activated. The positioning light-emitting plate 5 illuminates the light source according to the partial holes and slots inside the junction box. The laser centering sensor 208 (model: ON-TRAK) is activated. The OT-7000 guide plate 205 aligns with the irradiation slot inside the junction box, and the laser alignment sensor 208 collects the light source penetrating the slot, assisting the guide plate 205 in making lateral fine adjustments along the sliding frame 202. A small cylinder drives the lifting cylinder 204 to slide up along the slider 203 to adjust the guide plate 205 to be vertically aligned with the slot. The lifting cylinder 204's movable rod drives the beam rod to slide up along the slide rail 206. The linkage 213 slides up with the beam rod and slides along the irregular groove 207. The linkage 213 drives the second linear cylinder 210 to rotate 90 degrees clockwise through the shaft 214. The second linear cylinder 210 drives the fiber fusion disk to be aligned with the slot, and starts the rotary cylinder according to the data collected by the laser alignment sensor 208. The rotary cylinder adjusts the turntable, and the fiber fusion disk is finely adjusted to align with the slot as the turntable rotates. The second linear cylinder 210 drives the second suction cup 211 to move laterally closer to the slot inside the junction box, forming a light source calibration and bonding structure.

[0058] Step 4: The cylinder 603 on the locking sliding frame 6 drives the screw-operated robotic arm 602 to approach the exposed slots on the back of the transfer box, and screws are used to fix the slots of the transfer box frame and the fiber melting tray together. After the fiber melting tray inside the transfer box is fixed, the servo motor 406 drives the guide rod 405 to slide down and rotate 90 degrees, placing the transfer box onto the conveyor roller 101 and adsorbing and picking up the next set of transfer boxes.
