Description

Technical Field

[0001] This application relates to the field of injection molding equipment technology, and in particular to a fastener insertion mechanism. Background Technology

[0002] In the manufacturing process of digital products, their outer shell structure typically requires precise and reliable connection and fixation to internal components or other external parts. To achieve this, a common method is to pre-install metal nuts inside the plastic shell for subsequent assembly with screws. The mainstream nut insertion technology is insert injection molding. This process involves manually placing the pre-made nut into the cavity of the injection mold before the plastic part is injection molded, followed by mold closing and injection molding. The molten plastic material fills the cavity under high pressure, encapsulating and firmly embedding the nut inside the plastic shell, thus forming an integrated internal threaded structure. This method ensures the strength, stability, and durability of the threaded connection, avoiding the risk of insufficient strength or thread slippage caused by later tapping. However, currently, nut loading is done manually, which is slow, resulting in a slow subsequent nut insertion speed and causing production inconvenience. Utility Model Content

[0023] Reference Figures 1 to 8The fastener insertion mechanism of the present application includes: a frame 100, and a connecting frame 110 is provided on the top of the frame 100; The feeding mechanism 200 is located inside the connecting frame 110 and is used to feed nuts and washers; The material receiving mechanism 300 is located on the top of the frame 100 and is used to receive the washers and nuts from the feeding mechanism 200. The feeding mechanism 200 includes a first moving device 210, a lifting device 220, a nut vibration conveying device 230, a movable plate 221, and a nut feeding device 240. The first moving device 210 is located inside the connecting frame 110, the lifting device 220 is located on one side of the first moving device 210, the movable plate 221 is located on one side of the lifting device 220, the nut feeding device 240 is located on one side of the movable plate 221, and the nut vibration conveying device 230 is located on the top of the connecting frame 110. The nut feeding device 240 includes a support plate 241, a nut conveying hose 242, a nut conveying air pump 2421, and a connecting seat 244. The support plate 241 is located on one side of the movable plate 221, and the connecting seat 244 is located on one side of the support plate 241. The connecting seat 244 has a discharge hole 2446 inside. The nut conveying air pump 2421 is located on the top of the connecting seat 244. The air outlet of the nut conveying air pump 2421 is connected to the discharge hole 2446. One end of the nut conveying hose 242 is connected to the air extraction end of the nut conveying air pump 2421, and the other end of the nut conveying hose 242 is connected to the discharge end of the nut vibrating conveying device 230.

[0024] Understandably, when nuts are being fed, the nut vibration conveying device 230 uses vibration to orient the nuts to the nut conveying hose 242. The nut conveying air pump 2421 generates airflow, which draws the nuts from the nut conveying hose 242 through the suction end of the nut conveying air pump 2421, and then blows the nuts to the discharge hole 2446 inside the connecting seat 244 through the air outlet end of the nut conveying air pump 2421. This pneumatic conveying method achieves rapid and continuous supply of nuts. Then, the movable plate 221 drives the nut feeding device 240 to move and lift under the drive of the first moving device 210 and the lifting device 220, thereby adjusting the position of the discharge hole 2446. Finally, the discharge hole 2446 on the connecting seat 244 releases the nuts onto the waiting-to-catch mechanism 300, ensuring that the nuts can be implanted by the subsequent robotic arm, thereby improving the nut implantation efficiency.

[0025] Reference Figures 4 to 5According to some embodiments of this application, the nut feeding device 240 includes a discharge seat 2441, a discharge cylinder 2443, a distributing seat 245, a distributing cylinder 2451, and a distributing slider. The discharge seat 2441 is located at the bottom of the connecting seat 244. A movable cavity 2442 is formed inside the discharge seat 2441, and a discharge hole 2446 communicates with the movable cavity 2442. The movable cavity 2442 passes through one end of the discharge seat 2441. The distributing slider 2452 is slidably engaged with the movable cavity 2442. The distributing seat 245 is located on one side of the connecting seat 244, and the distributing cylinder 2451 is located on one side of the distributing seat 245. The piston rod of cylinder 1 passes into the movable cavity 2442, connecting the piston rod of the distributing cylinder 2451 with the distributing slider 2452. The discharge cylinder 2443 is located at the bottom of the discharge seat 2441. The discharge cylinder 2443 has a discharge channel 2444 inside, which communicates with the movable cavity 2442. The distributing slider 2452 has a distributing through hole 2453 inside. When the distributing slider 2452 slides toward the discharge hole 2446, the discharge hole 2446 communicates with the distributing through hole 2453. When the distributing slider 2452 slides toward the discharge channel 2444, the discharge hole 2446 communicates with the discharge channel 2444.

[0026] Understandably, when the nut conveying air pump 2421 operates, it draws the nut out of the nut vibrating conveying device 230 through the nut conveying hose 242 and blows it in through the discharge hole 2446 on the connecting seat 244. At this time, the piston rod of the distributing cylinder 2451 is in a retracted state, driving the distributing slider 2452 to move to a position close to the discharge hole 2446. This aligns the distributing through hole 2453 inside the distributing slider 2452 with the discharge hole 2446. Nuts falling from the discharge hole 2446 do not fall directly but enter the distributing through hole 2453 of the distributing slider 2452 and are temporarily stored. This step achieves precise capture and temporary storage of a single nut. When it is necessary to feed the material-catching mechanism 300, the distributing cylinder 2451 drives the distributing slider 2452 to slide towards the discharge channel 2444. During the sliding process, the top surface of the distributing slider 2452 without the distributing through hole 2453 will slide... When the material reaches below the discharge hole 2446, it instantly and completely isolates the upstream discharge hole 2446 from the downstream discharge channel 2444. This ensures that a second nut will not be accidentally blown in during the process of pushing out one nut, thus avoiding material jamming or double material. When the material distribution slider 2452 slides close to the discharge channel 2444, the material distribution through hole 2453 inside the material distribution slider 2452 is aligned with the bottom discharge channel 2444. The nut in the material distribution through hole 2453 loses its support and falls into the discharge channel 2444 under the action of gravity, and then falls to the waiting material grabbing mechanism 300 through the discharge cylinder 2443. Through the physical isolation effect of the material distribution slider 2452, it is strictly guaranteed that only one nut is allowed to pass through at a time, which completely solves the problem of blockage, collision and jamming at the outlet caused by the continuous discharge of multiple nuts in pneumatic conveying, and ensures the continuity and stability of production.

[0027] Reference Figures 4 to 5 According to some embodiments of this application, the nut feeding device 240 includes a top material seat 243, a top material cylinder 2431, and a top material rod 2432. The top material seat 243 is located on one side of the support plate 241, the top material rod 2432 is located at the bottom of the support plate 241, and the top material cylinder 2431 is located at the top of the support plate 241. The top material cylinder 2431 drives the top material rod 2432 to rise and fall. A top material hole 2445 is provided inside the connecting seat 244. The top material hole 2445 communicates with the movable cavity 2442. One end of the top material rod 2432 passes through the top material hole 2445. When the material distribution through hole 2453 communicates with the discharge channel 2444, the top material hole 2445 communicates with the material distribution through hole 2453.

[0028] Understandably, nuts may stick to the inner wall of the distribution hole 2453 due to minor oil stains, burrs, or static electricity, and cannot be reliably removed by gravity alone. When the distribution hole 2453 inside the distribution slider 2452 is aligned with the bottom discharge channel 2444, the top of the distribution hole 2453 is also aligned with the top hole 2445 on the connecting seat 244. The top cylinder 2431 drives the top rod 2432 to descend, so that the top rod 2432 passes through the top hole 2445, the distribution hole 2453 and the discharge channel 2444 in sequence, thereby pushing the nut out to the discharge channel 2444. This ensures that every nut transported by the distribution slider 2452 can be successfully released, fundamentally avoiding production interruptions caused by material jamming.

[0029] Reference Figures 1 to 8 According to some embodiments of this application, the feeding mechanism 200 includes a gasket vibration conveying device 250 and a gasket feeding device 260. The gasket feeding device 260 is located on one side of the movable plate 221, and the gasket vibration conveying device 250 is located on the top of the frame 100. The gasket vibration conveying device 250 is used to convey gaskets, and the gasket feeding device 260 is used to feed the conveyed gaskets.

[0030] Understandably, the gasket vibrating conveyor 250 is responsible for picking up the gasket from the outlet of the gasket vibrating conveyor 250 and placing it into the material-catching mechanism 300, which is driven by the first moving device 210 and the lifting device 220, together with the moving plate 221, so that the gasket can be easily picked up by the gasket loading device 260 and placed into the material-catching mechanism 300, so as to facilitate the subsequent insertion of the gasket.

[0031] It's important to note that washers need to be added after the nut is inserted. This is because vibrations during the operation or transportation of digital products can cause the screws to loosen after assembly. Washers provide continuous pressure to the connection, effectively preventing the nut from loosening and ensuring the long-term reliability of the connection. This is especially important for precision digital products.

[0032] Reference Figure 4 According to some embodiments of this application, the gasket feeding device 260 includes a feeding bracket 261, an extension cylinder 262, a pneumatic finger 263, and movable gripping fingers 264. The feeding bracket 261 is located on one side of the movable plate 221, the extension cylinder 262 is located on the top of the feeding bracket 261, and the pneumatic finger 263 is located on the bottom of the feeding bracket 261. The extension cylinder 262 drives the pneumatic finger 263 to rise and fall. There are two movable gripping fingers 264, which are located at the bottom of the pneumatic finger 263. The two movable gripping fingers 264 are separated to form a clamping interval 265. The pneumatic finger 263 drives the two movable gripping fingers 264 to open and close.

[0033] Understandably, when a gasket needs to be fed, the first moving device 210 and the lifting device 220 drive the movable plate 221 to move the pneumatic finger 263 above the discharge port of the gasket vibrating conveyor 250. The pneumatic finger 263 drives the two movable clamping fingers 264 to close, clamping the gasket through the clamping interval 265, so as to feed the gasket to the material-catching mechanism 300.

[0034] Reference Figures 1 to 8 According to some embodiments of this application, the material-catching mechanism 300 includes a second moving device 310, a moving plate 311, a first placement plate 320, a picking rod 321, and a washer limiting head 322. The second moving device 310 is located on the top of the frame 100, the moving plate 311 is located on the top of the second moving device 310, the first placement plate 320 is located on the top of the moving plate 311, there are multiple picking rods 321, multiple picking rods 321 are located on the top of the first placement plate 320, there are multiple washer limiting heads 322, multiple washer limiting heads 322 are respectively located on the top of multiple picking rods 321, and the washer limiting head 322 is used for washer sleeve placement.

[0035] Understandably, after the gasket feeding device 260 removes the gasket, it will move above the gasket limiting head 322 and place the gasket on the gasket limiting head 322, thereby preventing the gasket from detaching from the waiting-to-catch mechanism 300 before it is caught by the robotic arm.

[0036] Reference Figures 6 to 8 According to some embodiments of this application, the material handling mechanism 300 includes a movable cylinder 323, a second placement plate 330, a connecting block 331, a nut placement part 340, and the second placement plate 330 is hinged to one side of the first placement plate 320. The movable cylinder 323 is located on the top of the first placement plate 320, and the connecting block 331 is located on the top of the second placement plate 330. The piston rod of the movable cylinder 323 is hinged to the connecting block 331. There are multiple nut placement parts 340, which are located on the top of the second placement plate 330 and are used for nut placement.

[0037] Understandably, when the nut is placed in the nut placement part 340 and the washer is placed on the washer limiting head 322, the movable cylinder 323 drives the connecting block 331 to move, so that the connecting block 331 drives the second placement plate 330 to rotate closer to the first placement plate 320. When the second placement plate 330 rotates to an inclined state, it provides optimal accessibility for the robot above, and the robot can directly approach vertically downwards so that the robot can simultaneously grasp the washer and the nut.

[0038] Reference Figures 6 to 8According to some embodiments of this application, the nut placement part 340 includes a placement cylinder 341, which is disposed on the top of the second placement plate 330, and a placement cavity 342 is formed on the top of the placement cylinder 341.

[0039] Understandably, when the nut feeding device 240 picks up the nut and places it into the material-catching mechanism 300, the nut is placed into the placement cavity 342 of the placement cylinder 341. This ensures that the radial (horizontal) position of the nut is completely constrained and determined after it falls in, preventing any shaking. This ensures that the nut is temporarily placed in the placement cavity 342 of the placement cylinder 341 in a uniform and correct posture (e.g., the threaded hole axis is perpendicular to the placement plate), so as to unify the position of the robot arm in picking up the nut.

[0040] Reference Figures 6 to 8 According to some embodiments of this application, the nut placement includes two limiting balls 344, and the placement cylinder 341 has mounting grooves 343 on both sides. The mounting grooves 343 are connected to the placement cavity 342. The two limiting balls 344 are elastically connected to the two mounting grooves 343 respectively, so that one side of the two limiting balls 344 protrudes into the interior of the placement cavity 342.

[0041] Understandably, when the nut is placed into the placement cavity 342, its outer wall will contact the two limiting balls 344 protruding into the cavity. As the nut is pushed downwards, it will compress the limiting balls 344. The elastic element (usually a spring or other elastic material) of the limiting balls 344 is compressed, allowing the limiting balls 344 to slightly retract into the mounting groove 343, thereby making way for the nut so that it can smoothly reach the bottom of the placement cavity 342. After the nut passes the limiting balls 344, the limiting balls 344 lose the compression of the nut's side wall, and the reset ball resets, thereby limiting the vertical direction of the nut and preventing the nut from dislodging from the placement cavity 342 when the second placement plate 330 rotates.

[0042] Reference Figures 6 to 8 According to some embodiments of this application, the nut placement includes an ejector block 338, an ejector cylinder 335, and an ejector rod 336. The ejector cylinder 335 is located at the bottom of the second placement plate 330, the ejector block 338 is located at one end of the ejector cylinder 335, and the ejector rod 336 is located on one side of the ejector block 338. An ejector groove 337 is provided in the second placement plate 330, and the ejector groove 337 communicates with the placement cavity 342. One end of the ejector rod 336 passes through the interior of the ejector groove 337.

[0043] Understandably, when the nut needs to be picked up by an external robotic arm, the ejector cylinder 335 is driven, which in turn drives the ejector rod 336 to move. The ejector rod 336 lifts the nut upwards. At this time, under the thrust of the ejector rod 336, the limit ball 344 will retract, allowing the nut to detach from the placement cavity 342. This enables the robotic arm to pick up the nut at a consistent and clearly defined height, eliminating posture deviations caused by varying depths of the picking position. This provides a better guarantee for the subsequent precise implantation of the assembly into the mold cavity.

[0044] The embodiments of this application have been described in detail above with reference to the accompanying drawings. However, this application is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of this application. Furthermore, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.
