An automatic oil injection equipment for folding screen hinge

Abstract

The application relates to the folding screen hinge oil injection technical field, in particular to an automatic oil injection equipment for a folding screen hinge, which comprises a rack, a rotating mechanism, a feeding mechanism, an oil injection mechanism, a visual detection mechanism and a discharging mechanism; the rotating mechanism drives the folding screen hinge to pass through an oil injection station and a detection station in sequence from a feeding station in a clockwise direction, and then reaches a discharging station. When the folding screen hinge to be injected reaches the oil injection station, the oil injection mechanism injects lubricating oil into the mounting hole of the folding screen hinge. When the folding screen hinge after oil injection reaches the detection station, the visual detection mechanism detects whether the lubricating oil exists in the mounting hole of the folding screen hinge. When the folding screen hinge after oil injection reaches the discharging station, the discharging mechanism makes the folding screen hinge separate from the rotating mechanism. Compared with the existing vertical dispensing mode, the oil injection mechanism adopts a lateral oil injection mode to inject lubricating oil into the mounting hole of the folding screen hinge, effectively reduces the oil injection difficulty, and guarantees the oil injection effect.

Description

Technical Field

[0001] This application relates to the field of foldable screen hinge lubrication technology, and in particular to an automated lubrication device for foldable screen hinges. Background Technology

[0002] The hinge, used in foldable phones, is the core mechanical structure connecting the phone screen. Its design determines the screen's flatness, durability, and opening / closing feel. To ensure smooth opening and closing, reduce wear, and extend the hinge's lifespan, a measured amount of lubricating oil needs to be injected into the hinge's mounting holes.

[0003] Currently, the main method used is to inject lubricating oil into the mounting holes of the folding screen hinge using a vertical dispensing method.

[0004] The existing technical solutions described above have the following drawbacks: Due to the small overall size and extremely precise structure of the folding screen hinge, the diameter of its mounting holes is only 0.5mm-1mm. When injecting lubricating oil into the mounting holes of the folding screen hinge using a vertical dispensing method, the oil injection is difficult and the oil injection effect is hard to guarantee. Summary of the Invention

[0005] To reduce the difficulty of oiling and improve the oiling effect, this application provides an automated oiling device for foldable screen hinges.

[0006] This application provides an automated oiling device for foldable screen hinges, employing the following technical solution: An automated lubrication device for foldable screen hinges, comprising: frame; The rotating mechanism, mounted on the frame, is used to carry and drive the folding screen hinge from the loading station through the oiling station and the inspection station, and then to the unloading station. The feeding mechanism, mounted on the frame, is used to transfer the folding screen hinge facing upwards to the feeding station; The oiling mechanism, mounted on the frame, is used to inject lubricating oil into the mounting holes of the folding screen hinge that abuts the oiling station. The visual inspection mechanism, mounted on the frame, is used to detect whether there is lubricating oil in the mounting holes of the folding screen hinge that reaches the inspection station; The unloading mechanism, mounted on the frame, is used to disengage the hinge of the folding screen that has reached the unloading station from the rotation mechanism.

[0007] By adopting the above technical solution, the loading mechanism transfers the folding screen hinge to be oiled onto the rotating mechanism. The rotating mechanism drives the folding screen hinge clockwise from the loading station, through the oiling station and the inspection station, before reaching the unloading station. The rotating mechanism allows the folding screen hinge to move quickly between stations, effectively improving flow efficiency and thus oiling efficiency. Simultaneously, it effectively reduces the space occupied by the equipment. When the folding screen hinge to be oiled reaches the oiling station, the oiling mechanism injects lubricating oil into the mounting hole of the folding screen hinge. When the oiled folding screen hinge reaches the inspection station, the vision inspection mechanism checks whether there is lubricating oil in the mounting hole and the oiling status. When the oiled folding screen hinge reaches the unloading station, the unloading mechanism disengages the folding screen hinge from the rotating mechanism. Compared to the existing vertical dispensing method, the oiling mechanism uses a lateral oiling method to inject lubricating oil into the mounting hole of the folding screen hinge, effectively reducing the difficulty of oiling and ensuring the oiling effect.

[0008] This application further specifies that the oil injection mechanism includes: The first linear module is set along the Y-axis and fixed on the frame; The second linear module is set along the X-axis and fixed to the top of the slide of the first linear module; The manual displacement platform is fixed to the top of the second linear module; The Z-axis fine-tuning platform is fixed to the top of the manual displacement platform; The oil injection component is tilted and its bottom end is rotatably connected to the first support plate. It is used to inject lubricating oil into the mounting holes of the folding screen hinge. The first adjusting bolt connects the top of the first support plate and the oil injection assembly through the first adjusting hole; The first linear module is used to drive the oil injection assembly to move along the Y-axis; the second linear module is used to drive the oil injection assembly to move along the X-axis; the manual displacement platform is used to drive the oil injection assembly to rotate around the θ-axis; the Z-axis fine-tuning platform is used to drive the oil injection assembly to move along the Z-axis; and the first adjusting bolt allows the tilt angle of the oil injection assembly to be adjusted.

[0009] By adopting the above technical solution, the first linear module drives the second linear module to move along the Y-axis, thereby moving the manual displacement platform, the Z-axis fine-tuning platform, the first support plate, and the oil injection assembly along the Y-axis, thus achieving precise adjustment of the oil injection assembly's position in the Y-axis direction. The second linear module drives the manual displacement platform to move along the X-axis, thereby moving the Z-axis fine-tuning platform, the first support plate, and the oil injection assembly along the X-axis, thus achieving precise adjustment of the oil injection assembly's position in the X-axis direction. The tilt angle of the oil injection assembly is adjusted using the first adjusting bolt and the first adjusting hole, achieving precise adjustment of the oil injection assembly's pitch angle. The Z-axis fine-tuning platform drives the first support plate to move along the Z-axis, thereby moving the oil injection assembly along the Z-axis, thus achieving precise adjustment of the oil injection assembly's position in the Y-axis direction. The manual displacement platform drives the Z-axis fine-tuning platform to rotate around the θ-axis, thereby rotating the first support plate and the oil injection assembly around the θ-axis, thus achieving precise adjustment of the oil injection assembly's yaw angle. In this way, when injecting oil into the mounting hole with an extremely small diameter, the flow area of ​​the lubricating oil is effectively increased, thereby effectively reducing the difficulty of oil injection and ensuring the oil injection effect.

[0010] This application further specifies that the oil injection assembly includes: The piezoelectric control module is tilted, with its bottom end rotatably connected to the first support plate and its top end connected to the first support plate via the first adjusting bolt. The oil reservoir is tilted and fixed to the piezoelectric control module by a support ring. A flow regulating valve block is installed at the output end of the oil reservoir and is equipped with a flow regulating knob. The flow guide block is fixed to the bottom of the piezoelectric control module and has a flow guide cavity inside that is connected to the flow regulating valve block; The oil injection head is fixed on the guide block and communicates with the guide cavity.

[0011] This application further specifies that the oil injection assembly also includes: The second support plate is inclined, with a second adjustment hole at the top and a constraint ring on one side of the bottom. The second adjusting bolt connects the second support plate and the support ring through the second adjusting hole, so that the position of the second support plate in the axial direction of the oil reservoir can be adjusted. The locking bolt is installed on the constraint ring, and one end can abut against or detach from the outer wall of the oil reservoir to restrict the axial movement of the oil reservoir or release the restriction on the oil reservoir.

[0012] This application further specifies that the feeding mechanism includes: The first support frame is fixed to the machine frame; A flexible vibratory feeder, mounted on the first support frame, is used to ensure that the front of the folding screen hinge faces upwards. The hopper is installed on the first support frame, with an inlet at the top and an outlet at the bottom; the outlet is located above the flexible vibrating plate. The spider-like robotic arm is mounted on the first support frame and has a first suction nozzle at the bottom, used to transfer the hinge of the folding screen in the flexible vibratory feeder to the loading station; the spider-like robotic arm is equipped with a first camera.

[0013] By adopting the above technical solution, the spider robotic arm and the first suction nozzle work together to enable the folding screen hinge to quickly and accurately land in a specific posture on a specific position on the rotating mechanism.

[0014] This application further specifies that the feeding mechanism includes: The second support frame is fixed to the machine frame; The third linear module is set along the X-axis and fixed on the second support frame; A linear actuator, vertically mounted, is fixed to the slide of the third linear module; The lifting plate is fixedly connected to the output end of the linear actuator; the linear actuator drives the lifting plate to move up and down. The second suction nozzle is fixed to the lifting plate and moves up and down with the lifting plate. The storage box is fixed on the frame and located below the third linear module, with a first feed port and a second feed port formed at the top. The lower drawer is located in the lower part of the storage box and is connected to the first feed inlet. The upper drawer is located in the upper part of the storage box and is connected to the second feed port.

[0015] By adopting the above technical solution, when the folding screen hinge reaches the unloading station, the third linear module drives the linear actuator to move along the X-axis, thereby moving the lifting plate and the second suction nozzle along the X-axis. The linear actuator drives the lifting plate to move up and down, thereby moving the second suction nozzle up and down. The second suction nozzle is used to transfer the folding screen hinge on the unloading station to directly above the first / second inlet, and allows the folding screen hinge to fall naturally into the lower / upper drawer, effectively ensuring unloading efficiency.

[0016] This application further specifies that the visual inspection agency includes: The third support frame has a third adjustment hole at its bottom. The third adjusting bolt connects the third support frame and the machine frame through the third adjusting hole, allowing the position of the third support frame in the X-axis direction to be adjusted. The fixing block has a fourth adjustment hole. The fourth adjusting bolt connects the top of the fixing block and the third support frame through the fourth adjusting hole, allowing the position of the fixing block on the Y-axis to be adjusted. The second camera is fixed to the top of the fixed block, with its lens facing the rotating mechanism; A coaxial light source is fixed to the top of the third support frame; A ring light source is fixed to the top of the third support frame and located on the side of the coaxial light source away from the second camera; the ring light source, the coaxial light source, and the second camera are coaxially arranged. A protective cover is installed over the second camera.

[0017] By adopting the above technical solution, the third adjusting bolt connects the third support frame and the machine frame through the third adjusting hole, allowing the position of the third support frame in the X-axis direction to be adjusted. This, in turn, allows the positions of the fixed block, the second camera, the coaxial light source, and the ring light source in the X-axis direction to be adjusted, thereby adjusting the visual inspection effect. The fourth adjusting bolt connects the fixed block and the top of the third support frame through the fourth adjusting hole, allowing the position of the fixed block in the Y-axis to be adjusted. This, in turn, allows the position of the second camera in the Y-axis to be adjusted, thereby achieving the purpose of adjusting the shooting effect. The coaxial light source is used to eliminate reflected light interference and highlight minor surface defects. The ring light source is used to provide uniform illumination, reduce shadows, and highlight the edges or three-dimensional features of objects.

[0018] This application further specifies that the rotating mechanism includes: The rotating disk is rotatably mounted above the top surface of the frame, and its edge is uniformly formed with multiple clearance notches along the circumference. Multiple support plates are evenly fixed to the top surface of the rotating disk along its circumference. There are multiple support blocks; every two support blocks are fixed to the top of the same support plate; each support block has a detection through hole. The first background plate consists of multiple plates, each corresponding to a support plate and fixed to the top of the support plate. The second background plate consists of multiple plates, which are evenly fixed to the top surface of the rotating disk along the circumference of the rotating disk. Rotary drive, fixed to the top of the frame; The gearbox is fixed to the top of the frame, with its input end fixedly connected to the output end of the rotary drive and its output end fixedly connected to the bottom end of the rotary disk. The positioning sensor, mounted on the frame, is used to detect whether the hinge of the folding screen has reached the loading station.

[0019] By adopting the above technical solution, the rotary disk, multiple support plates, and multiple load-bearing blocks work together to achieve simultaneous support and sequential transfer of multiple folding screen hinges, effectively improving the transfer efficiency between workstations. The first and second background plates work together to provide a clear background contrast for visual inspection, significantly improving the accuracy and stability of lubricant detection. The rotary driver, through a reduction gearbox, drives the rotary disk to rotate in a stepwise manner, precisely controlling the dwell position and duration at each workstation to ensure the reliability of the oiling and inspection processes.

[0020] This application further specifies that the rotating mechanism also includes: There are multiple pressure blocks; each pair of pressure blocks can move up and down and are rotatably positioned above the top surface of the same support plate. There are multiple rotary lifting actuators, each fixed to the bottom of the rotary disk, with the output end fixedly connected to each of the multiple pressure blocks.

[0021] By adopting the above technical solution, when both folding screen hinges to be oiled reach the loading station, the two rotary lifting actuators drive the corresponding pressure blocks to rotate downwards, thereby pressing the corresponding folding screen hinges against the top surface of the corresponding support blocks. This prevents displacement of the folding screen hinges during position transfer, oiling, and visual inspection, thus ensuring the oiling and visual inspection effects. When both folding screen hinges that have been oiled reach the unloading station, the two rotary lifting actuators drive the corresponding pressure blocks to rotate upwards, thereby releasing the corresponding folding screen hinges to facilitate the normal operation of the unloading process.

[0022] This application further includes: The control cabinet is mounted on the frame and is connected to the rotating mechanism, feeding mechanism, oiling mechanism, vision inspection mechanism, and unloading mechanism.

[0023] In summary, the beneficial technical effects of this application are as follows: 1. The loading mechanism transfers the folding screen hinge to be oiled onto the rotating mechanism. The rotating mechanism drives the folding screen hinge clockwise from the loading station, passing through the oiling station and the inspection station, before reaching the unloading station. The rotating mechanism allows the folding screen hinge to move quickly between stations, effectively improving flow efficiency and thus oiling efficiency. Simultaneously, it effectively reduces the space occupied by the equipment. When the folding screen hinge reaches the oiling station, the oiling mechanism injects lubricating oil into the mounting holes of the folding screen hinge. When the oiled folding screen hinge reaches the inspection station, the vision inspection mechanism checks whether lubricating oil is present in the mounting holes and the oiling status. When the oiled folding screen hinge reaches the unloading station, the unloading mechanism disengages the folding screen hinge from the rotating mechanism. Compared to the existing vertical dispensing method, the oiling mechanism uses a lateral oiling method to inject lubricating oil into the mounting holes of the folding screen hinge, effectively reducing the difficulty of oiling and ensuring the oiling effect.

[0024] 2. The first linear module drives the second linear module to move along the Y-axis, thereby moving the manual displacement platform, Z-axis fine-tuning platform, first support plate, and oil injection assembly along the Y-axis, achieving precise adjustment of the oil injection assembly's position in the Y-axis direction. The second linear module drives the manual displacement platform to move along the X-axis, thereby moving the Z-axis fine-tuning platform, first support plate, and oil injection assembly along the X-axis, achieving precise adjustment of the oil injection assembly's position in the X-axis direction. The tilt angle of the oil injection assembly is adjusted using the first adjusting bolt and first adjusting hole, achieving precise adjustment of the oil injection assembly's pitch angle. The Z-axis fine-tuning platform drives the first support plate to move along the Z-axis, thereby moving the oil injection assembly along the Z-axis, achieving precise adjustment of the oil injection assembly's position in the Y-axis direction. The manual displacement platform drives the Z-axis fine-tuning platform to rotate around the θ-axis, thereby rotating the first support plate and oil injection assembly around the θ-axis, achieving precise adjustment of the oil injection assembly's yaw angle. In this way, when injecting oil into the mounting hole with an extremely small diameter, the flow area of ​​the lubricating oil is effectively increased, thereby effectively reducing the difficulty of oil injection and ensuring the oil injection effect.

[0025] 3. The third adjusting bolt connects the third support frame and the machine frame through the third adjusting hole, allowing the position of the third support frame in the X-axis direction to be adjusted. This, in turn, allows adjustment of the positions of the fixed block, the second camera, the coaxial light source, and the ring light source in the X-axis direction, thereby adjusting the visual inspection effect. The fourth adjusting bolt connects the fixed block and the top of the third support frame through the fourth adjusting hole, allowing the position of the fixed block in the Y-axis to be adjusted. This, in turn, allows adjustment of the position of the second camera in the Y-axis, thus achieving the purpose of adjusting the shooting effect. The coaxial light source is used to eliminate reflected light interference and highlight minor surface defects. The ring light source is used to provide uniform illumination, reduce shadows, and highlight the edges or three-dimensional features of objects. Attached Figure Description

[0028] It should be noted that, as Figure 1 As shown, a mounting hole 320 is formed on one side of the folding screen hinge 300, and the diameter of the mounting hole 320 is 0.5mm-1mm. When applying lubricant, the front side 310 of the folding screen hinge 300 should face upwards. It should be noted that... Figure 1The direction of the middle arrow indicates the direction of lubricant flow.

[0029] The following is in conjunction with the appendix Figure 2-8 This application will be described in further detail.

[0030] Reference Figure 2 This application discloses an automated oiling device for foldable screen hinges, including a frame 110, a rotating mechanism 120, a loading mechanism 130, an oiling mechanism 140, a vision inspection mechanism 150, and an unloading mechanism 160. The frame 110 supports the rotating mechanism 120, the loading mechanism 130, the oiling mechanism 140, the vision inspection mechanism 150, and the unloading mechanism 160. The rotating mechanism 120, mounted on the frame 110, carries and drives the foldable screen hinge 300 from the loading station 210, sequentially through the oiling station 220 and the inspection station 230, to the unloading station 240. The loading mechanism 130, mounted on the frame 110, transfers the foldable screen hinge 300 with its front face 310 facing upwards from the loading station 210. The lubrication mechanism 140 is mounted on the frame 110 and is used to inject lubricating oil into the mounting hole 320 of the folding screen hinge 300 that abuts at the lubrication station 220. The visual inspection mechanism 150 is mounted on the frame 110 and is used to detect whether there is lubricating oil in the mounting hole 320 of the folding screen hinge 300 that abuts at the inspection station 230. The unloading mechanism 160 is mounted on the frame 110 and is used to disengage the folding screen hinge 300 that abuts at the unloading station 240 from the rotation mechanism 120.

[0031] The working process and principle of the automated lubrication equipment used for foldable screen hinges are as follows: The loading mechanism 130 transfers the folding screen hinge 300 to be oiled onto the rotating mechanism 120. It should be noted that the front side 310 of the transferred folding screen hinge 300 faces upwards. Then, the rotating mechanism 120 drives the folding screen hinge 300 clockwise from the loading station 210, through the oiling station 220 and the inspection station 230, before reaching the unloading station 240. The rotating mechanism 120 allows the folding screen hinge 300 to move rapidly between stations, effectively improving flow efficiency and thus oiling efficiency. Since the loading mechanism 130, oiling mechanism 140, visual inspection mechanism 150, and unloading mechanism 160 are located on the four sides of the rotating mechanism 120, the space occupied by the equipment is effectively reduced. When the folding screen hinge 300 to be oiled reaches the oiling station 220, the oiling mechanism 140 injects lubricating oil into the mounting hole 320 of the folding screen hinge 300. When the lubricated folding screen hinge 300 reaches the inspection station 230, the vision inspection mechanism 150 checks whether there is lubricating oil in the mounting hole 320 of the folding screen hinge 300 and the lubrication status. When the lubricated folding screen hinge 300 reaches the unloading station 240, the unloading mechanism 160 disengages the folding screen hinge 300 from the rotation mechanism 120. Compared with the existing vertical dispensing method, the lubrication mechanism 140 uses a side-lubrication method to inject lubricating oil into the mounting hole 320 of the folding screen hinge 300, effectively reducing the difficulty of lubrication and ensuring the lubrication effect.

[0032] Reference Figure 2 , Figure 3 and Figure 4 In one embodiment, the oiling mechanism 140 includes a first linear module 141, a second linear module 142, a manual displacement platform 143, a Z-axis fine-tuning platform 144, a first support plate 145, a first adjusting bolt (not shown in the figure), and an oiling assembly 147. The first linear module 141 is arranged along the Y-axis and fixed to the top surface of the frame 110. The second linear module 142 is arranged along the X-axis and fixed to the top of the slide of the first linear module 141. The manual displacement platform 143 is fixed to the top of the second linear module 142. The Z-axis fine-tuning platform 144 is fixed to the top of the manual displacement platform 143. The bottom end of the first support plate 145 is fixedly connected to the top of the Z-axis fine-tuning platform 144. A first adjusting hole 1451 with an arc shape is formed on the first support plate 145. The oiling assembly 147 is inclined and its bottom end is rotatably connected to the first support plate 145 for injecting lubricating oil into the mounting hole 320 of the folding screen hinge 300. The first adjusting bolt connects the top of the first support plate 145 and the oil injection assembly 147 through the first adjusting hole 1451.

[0033] The working process and principle of the oil injection mechanism 140 are as follows: The first linear module 141 drives the second linear module 142 to move along the Y-axis, thereby moving the manual displacement platform 143, the Z-axis fine-tuning platform 144, the first support plate 145, and the oil injection assembly 147 along the Y-axis, thus achieving precise adjustment of the position of the oil injection assembly 147 in the Y-axis direction. The second linear module 142 drives the manual displacement platform 143 to move along the X-axis, thereby moving the Z-axis fine-tuning platform 144, the first support plate 145, and the oil injection assembly 147 along the X-axis, thus achieving precise adjustment of the position of the oil injection assembly 147 in the X-axis direction. The tilt angle of the oil injection assembly 147 is adjusted using the first adjusting bolt and the first adjusting hole 1451, achieving precise adjustment of the pitch angle of the oil injection assembly 147. The Z-axis fine-tuning platform 144 drives the first support plate 145 to move along the Z-axis, thereby moving the oil injection assembly 147 along the Z-axis, thus achieving precise adjustment of the position of the oil injection assembly 147 in the Y-axis direction. The manual displacement platform 143 drives the Z-axis fine-tuning platform 144 to rotate around the θ-axis, thereby causing the first support plate 145 and the oil injection assembly 147 to rotate around the θ-axis, thus achieving precise adjustment of the yaw angle of the oil injection assembly 147. It should be noted that after the oil injection assembly 147 completes its position adjustment, the axial direction of the oil injection head 1475 of the oil injection assembly 147 should be aligned with... Figure 1 With the same direction of the middle arrows, the axis of the oil injection head 1475 is neither in the vertical plane containing the axis of the mounting hole 320 of the folding screen hinge 300, nor in the vertical plane containing the perpendicular line to the axis of the mounting hole 320 of the folding screen hinge 300, nor in the horizontal plane containing the axis of the mounting hole 320 of the folding screen hinge 300. Thus, when injecting oil into the extremely small diameter mounting hole 320, the lubricating oil inflow area is effectively increased, thereby effectively reducing the difficulty of oil injection and ensuring the oil injection effect.

[0034] Reference Figure 3 and Figure 4In one embodiment, the oil injection assembly 147 includes an oil reservoir 1471, a flow regulating valve block 1473, a guide block 1474, an oil injection head 1475, a second support plate 1476, a second adjusting bolt (not shown), a locking bolt 1477, and a piezoelectric control module 1478. The piezoelectric control module 1478 is inclined, with its bottom end rotatably connected to the first support plate 145 and its top end connected to the first support plate 145 via the first adjusting bolt, used to control whether lubricating oil flows out. The oil reservoir 1471 is inclined and fixed to the piezoelectric control module 1478 via a support ring 1472, used to store lubricating oil. The flow regulating valve block 1473 is installed at the output end of the oil reservoir 1471 and is equipped with a flow regulating knob 14731. By rotating the flow regulating knob 14731, the supply flow rate of lubricating oil can be adjusted, thereby precisely controlling the amount of lubricating oil injected. The flow guide block 1474 is fixed to the bottom end of the piezoelectric control module 1478, and has a flow guide cavity inside that communicates with the flow regulating valve block 1473, serving as a flow guide. The oil injection head 1475 is fixed on the flow guide block 1474 and communicates with the flow guide cavity, used to guide lubricating oil into the mounting hole 320 of the folding screen hinge 300. The second support plate 1476 is inclined, with a second adjustment hole 14761 formed at the top and a constraint ring 14762 formed on one side of the bottom end. The second adjustment bolt connects the second support plate 1476 and the support ring 1472 through the second adjustment hole 14761, so that the position of the second support plate 1476 in the axial direction of the oil reservoir 1471 can be adjusted, thereby making the position of the constraint ring 14762 in the axial direction of the oil reservoir 1471 adjustable. The locking bolt 1477 is installed on the constraint ring 14762, and one end can abut against or detach from the outer wall of the oil reservoir 1471 to restrict the axial movement of the oil reservoir 1471 or release the restriction on the oil reservoir 1471. In this way, the stability of the position of the oil reservoir 1471 is ensured, thereby ensuring the stability of the lubricating oil supply.

[0035] Reference Figure 2 and Figure 5In one embodiment, the feeding mechanism 130 includes a first support frame 131, a flexible vibrating plate 132, a hopper 133, and a spider robot 134. The first support frame 131 is fixed to the top surface of the frame 110, providing support for the flexible vibrating plate 132, the hopper 133, the spider robot 134, and the first camera. The flexible vibrating plate 132 is mounted on the first support frame 131 and can vibrate to ensure that the front 310 of the folding screen hinge 300 faces upward, effectively guaranteeing the flipping efficiency. The hopper 133 is mounted on the first support frame 131, with an inlet 1331 at the top and an outlet 1332 at the bottom. The outlet 1332 is located above the flexible vibrating plate 132. A large quantity of folding screen hinges 300 awaiting oiling enters the hopper 133 through the inlet 1331 for temporary storage and falls into the flexible vibrating plate 132 through the outlet 1332. A spider-like robotic arm 134 is mounted on a first support frame 131, with a first suction nozzle 135 installed at its bottom. This nozzle is used to transfer the folding screen hinge 300 from the flexible vibratory feeder 132 to the loading station 210. The spider-like robotic arm 134 and the first suction nozzle 135 work together to ensure the folding screen hinge 300 quickly and accurately lands at a specific position on the rotating mechanism 120 in a specific posture. The spider-like robotic arm 134 is equipped with a first camera, which captures images of the folding screen hinge 300 during its transfer, ensuring both loading efficiency and accuracy.

[0036] Reference Figure 2 and Figure 6In one embodiment, the feeding mechanism 160 includes a second support frame 161, a third linear module 162, a linear driver 163, a lifting plate 164, a second suction nozzle 165, a storage box 166, a lower drawer 167, and an upper drawer 168. The second support frame 161 is fixed to the top surface of the frame 110 and supports the third linear module 162, the linear driver 163, and the lifting plate 164. The third linear module 162 is arranged along the X-axis and fixed to the second support frame 161. The linear driver 163 is vertically arranged and fixed to the slide of the third linear module 162. The lifting plate 164 is fixedly connected to the output end of the linear driver 163. The linear driver 163 drives the lifting plate 164 to move up and down. The second suction nozzle 165 is fixed to the lifting plate 164 and moves up and down with the lifting plate 164. The storage box 166 is fixed to the frame 110 and located below the third linear module 162, with a first feed port 1661 and a second feed port 1662 formed at its top. A lower drawer 167 is located in the lower part of the storage box 166, communicating with the first feed port 1661, and is used to store the folding screen hinge 300 that has been oiled. An upper drawer 168 is located in the upper part of the storage box 166, communicating with the second feed port 1662, and is used to store the folding screen hinge 300 that has leaked oil. When the folding screen hinge 300 reaches the unloading station 240, the third linear module 162 drives the linear actuator 163 to move along the X-axis, thereby moving the lifting plate 164 and the second suction nozzle 165 along the X-axis. The linear actuator 163 drives the lifting plate 164 to move up and down, thereby moving the second suction nozzle 165 up and down. The second suction nozzle 165 is used to transfer the folding screen hinge 300 on the unloading station 240 to directly above the first feed port 1661 / second feed port 1662, and the folding screen hinge 300 naturally falls into the lower drawer 167 / upper drawer 168, effectively ensuring unloading efficiency.

[0037] Preferably, there are two second suction nozzles 165, each fixed to the lifting plate 164. This allows for the transfer of two folding screen hinges 300 at a time, further improving material handling efficiency.

[0038] Preferably, the linear actuator 163 can be a cylinder, hydraulic cylinder, or electric actuator, etc.

[0039] Reference Figure 2 and Figure 7In one embodiment, the visual inspection mechanism 150 includes a third support frame 151, a third adjusting bolt (not shown), a fixing block 152, a fourth adjusting bolt (not shown), a second camera 153, a coaxial light source 154, a ring light source 155, and a protective cover 156. A third adjusting hole 1511 is formed at the bottom end of the third support frame 151. The third adjusting bolt connects the third support frame 151 and the frame 110 through the third adjusting hole 1511, allowing the position of the third support frame 151 in the X-axis direction to be adjustable. This, in turn, allows the positions of the fixing block 152, the second camera 153, the coaxial light source 154, and the ring light source 155 in the X-axis direction to be adjustable, thereby adjusting the visual inspection effect. A fourth adjusting hole 1521 is formed on the fixing block 152. The fourth adjusting bolt connects the fixing block 152 and the top end of the third support frame 151 through the fourth adjusting hole 1521, allowing the position of the fixing block 152 in the Y-axis to be adjustable. This, in turn, allows the position of the second camera 153 in the Y-axis to be adjusted, thereby achieving the purpose of adjusting the shooting effect. The second camera 153 is fixed to the top of the fixed block 152, with its lens facing the rotating mechanism 120, for image acquisition. The coaxial light source 154 is fixed to the top of the third support frame 151 to eliminate reflected light interference and highlight minor surface defects. The ring light source 155 is fixed to the top of the third support frame 151 and located on the side of the coaxial light source 154 away from the second camera 153, for providing uniform illumination, reducing shadows, and highlighting the edges or three-dimensional features of objects. The ring light source 155, the coaxial light source 154, and the second camera 153 are coaxially arranged. A protective cover 156 is placed over the second camera 153 for protection.

[0040] Reference Figure 2 and Figure 8In one embodiment, the rotating mechanism 120 includes a rotating disk 121, a plurality of support plates 122, a plurality of support blocks 123, a first background plate 124, a plurality of second background plates 125, a rotating driver 126, a reduction gearbox, and a positioning detection sensor 127. The rotating disk 121 is rotatably disposed above the top surface of the frame 110, and its edge is uniformly formed with a plurality of clearance notches 1211 along its circumferential direction to avoid the detection light emitted by the positioning detection sensor 127. The plurality of support plates 122 are uniformly fixed to the top surface of the rotating disk 121 along its circumferential direction. Every two support blocks 123 are fixed to the top of the same support plate 122. Each support block 123 is used to support a folding screen hinge 300. A detection through-hole is formed on each support block 123 for the detection light emitted by the positioning detection sensor 127 to pass through. It should be noted that the axis of the mounting hole 320 of each folding screen hinge 300 located on the support block 123 forms an angle of 15-45° with the width direction of the corresponding support plate 122, which helps to reduce the difficulty of oiling. The rotating disk 121, multiple support plates 122 and multiple support blocks 123 cooperate to realize the simultaneous bearing and sequential flow of multiple folding screen hinges 300, effectively improving the transfer efficiency between workstations. Multiple first background plates 124 are fixed to the top of the support plates 122 one-to-one with the multiple support plates 122. Multiple second background plates 125 are evenly fixed to the top surface of the rotating disk 121 along the circumference of the rotating disk 121. It should be noted that each first background plate 124 is black, each second background plate 125 is white, and the area of ​​each second background plate 125 is larger than the area of ​​the corresponding first background plate 124. The first background plate 124 and the second background plate 125 work together to provide a clear background contrast for visual inspection, significantly improving the accuracy and stability of lubricant detection. The rotary driver 126 is fixed to the top of the frame 110. The gearbox is fixed to the top of the frame 110, with its input end fixedly connected to the output end of the rotary driver 126 and its output end fixedly connected to the bottom end of the rotary disk 121, used to reduce the rotational speed and increase the torque. The rotary driver 126 drives the rotary disk 121 to rotate in a stepwise manner through the gearbox, enabling precise control of the dwell position and duration at each station to ensure the reliability of the oiling and inspection processes. The position detection sensor 127 is installed above the top surface of the frame 110 to detect whether the folding screen hinge 300 has reached the loading station 210.

[0041] Preferably, the rotary driver 126 can be a servo motor, which has high motion accuracy. The rotary driver 126 can also be a stepper motor, which has lower manufacturing and maintenance costs.

[0042] Preferably, there are two position detection sensors 127, which can detect whether the two folding screen hinges 300 are respectively abutting the top surface of the corresponding support block 123 at one time.

[0043] Reference Figure 8 In one embodiment, the rotating mechanism 120 further includes multiple pressure blocks 128 and multiple rotary lifting actuators 129. Each pair of pressure blocks 128 is movable up and down and rotatably positioned above the top surface of the same support plate 122. The multiple rotary lifting actuators 129 are fixed to the bottom end of the rotating disk 121, with their output ends fixedly connected to the pressure blocks 128 in a one-to-one correspondence. When two folding screen hinges 300 to be oiled reach the loading station 210, the two rotary lifting actuators 129 respectively drive the corresponding pressure blocks 128 to rotate downwards, thereby pressing the corresponding folding screen hinges 300 against the top surface of the corresponding support block 123. This prevents the folding screen hinges 300 from shifting during position transfer, oiling, and visual inspection, thus ensuring the oiling and visual inspection effects. When both folding screen hinges 300 that have been oiled reach the unloading station 240, the two rotary lifting actuators 129 drive the corresponding pressure blocks 128 to rotate upwards, thereby releasing the corresponding folding screen hinges 300 to facilitate the normal operation of the unloading process.

[0044] Reference Figure 2 In one embodiment, the automated oiling equipment for folding screen hinges also includes a control cabinet 170. The control cabinet 170 is mounted on the top surface of the frame 110 and is electrically connected to the rotating mechanism 120, the feeding mechanism 130, the oiling mechanism 140, the vision inspection mechanism 150, and the unloading mechanism 160, respectively, for controlling their orderly operation. Overall, this effectively improves the level of intelligence, increasing oiling efficiency while ensuring product consistency.

[0045] The implementation principle of this embodiment is as follows: The loading mechanism 130 transfers the folding screen hinge 300 to be oiled to the rotating mechanism 120. The rotating mechanism 120 drives the folding screen hinge 300 clockwise from the loading station 210, through the oiling station 220 and the inspection station 230, and finally to the unloading station 240. The rotating mechanism 120 allows the folding screen hinge 300 to move quickly between the stations, effectively improving the flow efficiency and thus improving the oiling efficiency. Since the loading mechanism 130, the oiling mechanism 140, the visual inspection mechanism 150, and the unloading mechanism 160 are located on the four sides of the rotating mechanism 120, the space occupied by the equipment is effectively reduced. When the folding screen hinge 300 to be oiled reaches the oiling station 220, the oiling mechanism 140 injects lubricating oil into the mounting hole 320 of the folding screen hinge 300. When the lubricated folding screen hinge 300 reaches the inspection station 230, the vision inspection mechanism 150 checks whether there is lubricating oil in the mounting hole 320 of the folding screen hinge 300 and the lubrication status. When the lubricated folding screen hinge 300 reaches the unloading station 240, the unloading mechanism 160 disengages the folding screen hinge 300 from the rotation mechanism 120. Compared with the existing vertical dispensing method, the lubrication mechanism 140 uses a side-lubrication method to inject lubricating oil into the mounting hole 320 of the folding screen hinge 300, effectively reducing the difficulty of lubrication and ensuring the lubrication effect.
