Description

Technical Field

[0001] This utility model relates to the field of assembly equipment technology, and in particular to an automatic assembly equipment with damping hinges. Background Technology

[0002] Damped hinges are core connectors in furniture, home appliances, automobiles, and other fields. Their assembly quality directly impacts the user experience and lifespan of the product. With downstream industries demanding higher production capacity and quality, the need for automation in hinge assembly is increasingly urgent. However, existing equipment still has shortcomings. Firstly, manual assembly methods cannot meet the demands of large-scale, high-precision production of damped hinges. As a key component combining connection and buffering functions, damped hinges have stringent requirements for shaft embedding depth, damping force consistency, and hinge fit accuracy during assembly. In traditional manual assembly, operators must manually position, press, and inspect the hinge body and shaft. This is not only affected by the operator's skill level and the stability of force control, leading to frequent issues of excessively loose or tight shaft pressing, but also because manual inspection relies on visual inspection and simple tools, making it difficult to accurately identify hidden problems such as abnormal damping characteristics and minor appearance defects. The first problem is the poor stability of the quantity. Furthermore, the efficiency of manual assembly is limited by physiological constraints, making it unsuitable for the large-scale production demands of downstream industries. It also requires significant investment in labor and management costs, creating a triple contradiction of low efficiency, large quality fluctuations, and high costs, hindering the industrial upgrading of hinge production. Secondly, the vibratory feeder's discharge trough, as a crucial channel for materials from the feeding unit to the operating unit, is prone to blockages due to material stacking and friction. Existing equipment lacks a real-time, efficient blockage control mechanism, with neither precise blockage detection methods nor automated cleaning solutions. Blockages necessitate machine shutdown and manual disassembly and cleaning of the discharge trough, leading to prolonged production interruptions. Furthermore, the mechanical contact during manual cleaning can damage the inner wall of the discharge trough and deform the material, further exacerbating the risk of subsequent blockages. This creates a vicious cycle of blockages, shutdowns, damage, and increased blockages, severely reducing the effective operating time of the equipment and failing to meet the actual needs of continuous production.

In addition, the device's human-machine interface and maintenance design have been further optimized. Intuitive status feedback, adjustable control units, and modular component installation structures lower the skill threshold for operators, simplify subsequent maintenance processes, and reduce equipment downtime. This ensures continuous production stability while reducing the overall lifecycle maintenance costs of the equipment, demonstrating outstanding technical practicality and economic value.

[0017] Working Principle: Using this invention, the operator first turns on the main power supply. The electrical control box 3 inside the frame 1 then starts, providing stable electrical and pneumatic power to all actuators, including the first vibratory feeder 4, second vibratory feeder 6, third vibratory feeder 8, product transfer device 9, indexing plate 10, and shaft core presser 11. Simultaneously, the horizontal position of the electrical controller 15 can be adjusted via the guide rail 14 to accommodate operators of different heights. Then, the necessary process parameters for hinge assembly are set on the electrical controller 15, including the vibratory feeder operating frequency, shaft core pressing force threshold, and finished product sorting logic. Next, the inspection door 2 on one side of the frame 1 is checked to ensure it is tightly closed, preventing internal leakage during equipment operation. Exposed moving parts pose a safety risk. Open the door 18 on one side of the outer wall of the working chamber 16 and observe the interior of the working chamber 16 through the transparent window 19 on the door 18. Confirm that there are no foreign objects obstructing the surfaces of core components such as the product transfer device 9, indexing plate 10, shaft core presser 11, and discharge sorter 12, or that their positions are misaligned. After confirming everything is correct, close the door 18. At this time, the warning light 17 on the upper surface of the working chamber 16 illuminates green, indicating that the equipment has completed initialization and entered the standby state. Then, the material feeding stage begins. The operator adds different materials required for assembling the damped hinges to the first vibrating plate 4, the second vibrating plate 6, and the third vibrating plate 8, respectively. The first vibrating plate 4 contains the hinge body, the second vibrating plate 6 contains the hinge damping sheet, and the third vibrating plate 8 contains... After placing the shaft core and initiating the vibratory feeder operation command, the first vibratory feeder 4 uses high-frequency vibration to orderly organize the internally stacked hinge bodies, gradually conveying them along the spiral track within the feeder to the first discharge chute 5, and then into the working chamber 16 via the end of the first discharge chute 5. The second vibratory feeder 6 uses the same high-frequency vibration principle to orderly convey the damping sheets to the second discharge chute 7, which also ultimately enters the working chamber 16 via the end of the second discharge chute 7. The third vibratory feeder 8, located on one side of the outer wall of the working chamber 16, directly conveys the output shaft cores to a pre-set material storage area within the working chamber 16, preparing material for subsequent shaft core pressing processes. During the process of material being conveyed to the working chamber 16 through the first discharge chute 5 and the second discharge chute 7, the working chamber... The first infrared sensor 20 and the second infrared sensor 25, located at the ends of the two discharge troughs on the inner wall of the working chamber 16, are always in real-time monitoring mode. The first infrared sensor 20 is fixedly connected to the first mounting hole 23 on the inner wall of the working chamber 16 via a bolt 22 passing through its own first fixing hole 21. The second infrared sensor 25 is fixed to the second mounting hole 27 on the inner wall of the working chamber 16 via a bolt 22 passing through its own second fixing hole 26. The signal lines of both infrared sensors are connected to the electrical controller 15 through wire holes 24 on the inner wall of the working chamber 16. The flow of materials in the discharge troughs is continuously monitored by infrared beams. If the irregular shape of the material causes accumulation and blockage, it will block the light emitted by the infrared sensors.The sensor immediately sends a blockage signal to the electrical controller 15, which then triggers the blockage handling mechanism. This mechanism activates the jet nozzle 30 at the end of the discharge chute on the inner wall of the working chamber 16. The jet nozzle 30 is fixed to the inner wall of the working chamber 16 via a clamp 29 and a ball hinge 28. The ball hinge 28 allows for angle adjustment, precisely adjusting the jet direction according to the direction of the discharge chute and the location of the blockage. Compressed air is ejected through the jet nozzle 30, dispersing the stacked material. Simultaneously, the through-hole 31 on the inner wall of the working chamber 16 not only serves as the air pipe routing for the jet nozzle 30 but also allows for timely removal of excess airflow generated during the blockage handling process, preventing excessive air pressure within the working chamber 16 from affecting the normal operation of other components. If the blockage persists for more than three seconds without resolution, the warning light 17 will illuminate. The warning changes from green to yellow, prompting operators to promptly check the inside of the discharge chute. Once the material successfully passes through the discharge chute and enters the working chamber 16, the electrical controller 15 sends a material transfer command to the product transfer device 9. The product transfer device 9 starts and, following a preset path, grabs the hinge body conveyed by the first discharge chute 5, the damping plate conveyed by the second discharge chute 7, and the shaft core temporarily stored by the third vibratory plate 8. These materials are then sequentially transferred to the indexing plate 10 located at the center of the bottom surface of the working chamber 16. The indexing plate 10 uses an intermittent rotation structure, rotating at a fixed angle each time to gradually transfer the material to different workstations. First, the indexing plate 10 transfers the hinge body to the damping plate assembly position, and the product transfer device 9 precisely assembles the damping plate onto the hinge body. The damping plate and the hinge body are initially assembled in the preset mounting slot. Then, the indexing plate 10 continues to rotate, transferring the hinge with the damping plate assembled to the core pressing position. At this time, the core pressing device 11 set in the working chamber 16 starts and moves downward according to the pressing force and pressing stroke preset by the electrical controller 15, smoothly pressing the core placed in the hinge core hole by the product transfer device 9 into the hinge, completing the core assembly process of the damped hinge. After the core pressing process is completed, the indexing plate 10 continues to rotate, transferring the assembled damped hinge to the finished product inspection and sorting position. The electrical controller 15 is linked to the discharge sorter 12 set on the outer wall of one side of the working chamber 16 to start working. The discharge sorter 12 sorts the assembled hinge according to the preset detection logic. The system performs a pass / fail judgment on the hinges. If the hinges pass the test, the pneumatic paddle of the discharge sorter 12 will move towards the preset pass channel, guiding the qualified hinges into the hopper 13 below. If the hinges fail the test, the paddle will switch directions, guiding the unqualified hinges into the independent unqualified product area within the hopper 13. This achieves automatic sorting and classified storage of finished products, preventing the mixing of qualified and unqualified products. Throughout the entire operation of the equipment, the electrical controller 15 will collect real-time operating data from each component, including the actual operating frequency of the vibratory feeder, the real-time pressing force of the shaft core presser 11, the number of times material blockage occurs, the quantity of finished products produced, and the pass rate. This data will be dynamically displayed on its own screen, allowing operators to monitor the production progress and equipment status in real time.The warning light 17 changes color according to different operating states of the equipment. Besides green for normal operation and yellow for material blockage warnings, if a component malfunctions, the warning light 17 immediately switches to red and triggers a shutdown protection. Simultaneously, the electrical controller 15 displays the location of the fault. Operators can observe the operation of various components inside the working chamber 16 at any time through the transparent window 19 on the chamber door 18, without needing to open the door 18. When the equipment requires regular maintenance or troubleshooting, operators first turn off the main power supply and open the inspection door 2 on one side of the frame 1 to inspect and maintain the electrical components and wiring connections of the internal electrical control box 3. After opening the chamber door 18 of the working chamber 16, easily worn components such as the first infrared sensor 20, the second infrared sensor 25, and the jet nozzle 30 can be replaced or calibrated by disassembling bolts 22, clamps 29, and other connecting parts, ensuring the equipment maintains a stable operating state over the long term.
