Abstract
Description
Technical Field
[0001] This invention relates to the field of nut picking technology, specifically a mechanical nut picking component for mobile phones. Background Technology
[0002] In the current electronics manufacturing industry, component designs are becoming increasingly precise and miniaturized, with complex and irregular shapes. Ultra-precision machining processes significantly increase the production cost of individual components, and stringent requirements are placed on component appearance. As product assembly tolerances shrink, the difficulty of picking up and placing nuts increases dramatically. Current nut-picking mechanisms lack the stability required for on-site production. After assembly, these mechanisms often lift nuts from the workpiece, necessitating reassembly and significantly reducing assembly efficiency.
[0003] A nut pickup fixture and nut assembly method are disclosed in publication number "CN111168360A". The nut pickup fixture includes an adsorption sleeve, a push pin, and a moving mechanism. The adsorption sleeve has an adsorption perforation and a first evacuation hole, which communicates with the adsorption perforation. The push pin is movably disposed in the adsorption perforation and has a connecting end and an adsorption end. The moving mechanism is connected to the connecting end of the push pin and drives the push pin to move within the adsorption perforation. In this application, the nut pickup fixture uses the push pin to adsorb the nut to be assembled. Then, by moving the nut pickup fixture to the nut assembly station, the nut adsorbed by the push pin is placed on the nut assembly station. Finally, the moving mechanism pushes the push pin, and the push pin pushes the nut onto the nut assembly station. By moving the push pin within the adsorption perforation through the moving mechanism, the push pin pushes the nut onto the workpiece in a tapping manner during nut assembly, ensuring the nut is securely fixed to the workpiece and effectively improving assembly efficiency.
[0004] However, the existing technology and the above-mentioned technology still have the following drawbacks:
[0005] Most machine housings are designed with hoppers and trays for feeding. Without stopping the machine, the safety door can be opened to manually replenish the nut bin online. However, because some nuts are small and light, incomplete feeding is very likely to occur during the feeding process, and it may also obstruct the subsequent entry of nuts. Summary of the Invention
[0006] This invention provides a mechanical nut picking component for mobile phones, which solves the problem mentioned in the background art that most machine casings are designed with hoppers and trays for feeding.

[0011] As an optional embodiment of the mechanical picking assembly for a mobile phone nut described in this invention, wherein: a first eccentric wheel is fixedly installed on the surface of the support shaft below the moving plate, an extension plate is installed at the bottom of the moving plate, a top rod is connected to the bottom surface of the extension plate, a ball head is provided at the bottom end of the top rod, and a limiting groove matching the ball head is opened in the first eccentric wheel.
[0012] As an optional embodiment of the mechanical picking assembly for mobile phone nuts described in this invention, the support shaft is provided with bearing seats at both ends, the bearing seats are fixedly installed on the inner wall of the cabinet, and torsion springs are provided at both ends of the bearing seats and the support shaft.
[0013] As an optional embodiment of the mechanical picking component for mobile phone nuts described in this invention, the following is provided: two sets of supports are provided below the receiving tray inside the cabinet, the supports and the receiving tray are pin-connected, the receiving tray is inclined, two sets of connecting blocks are symmetrically provided on the bottom surface of the receiving tray, and double-ear supports are connected to the supports, the connecting blocks and the double-ear supports are pin-connected.
[0014] As an optional embodiment of the mechanical pickup assembly for mobile phone nuts described in this invention, one of the supports is provided with two sets of second eccentric wheels on one side, and the second eccentric wheels are provided with annular grooves, and one end of the traction rope is fitted and wound around the two sets of annular grooves.
[0015] As an optional embodiment of the mechanical picking assembly for mobile phone nuts described in this invention, wherein: a plate is connected to one side of the receiving tray, a top block is connected above the receiving tray above the plate, one end of the top block has an inclined surface, and a connecting plate is provided on one side of the receiving tray.
[0016] As an optional embodiment of the mechanical picking assembly for a mobile phone nut described in this invention, the second eccentric wheel is connected to a lever at its top, a lever block is slidably connected to one side of the insert plate, a lever groove is formed in the lever block, the top end of the lever extends into the lever groove, and the lever and the lever are fitted with a clearance.
[0017] The present invention has the following beneficial effects:
[0018] 1. The mobile phone nut mechanical pickup assembly has two sets of movable frames arranged in sequence in the cabinet, which drive the pickup to move in the X and Y directions respectively. It can move as far as possible above the receiving tray, which can check whether the nuts are missing, reversed or stacked, and can ensure that the pickup can pick up the nuts as completely as possible.
[0019] 2. This mobile phone nut mechanical pickup assembly has two sets of tracks symmetrically arranged on the inner wall of the cabinet, and a movable plate slidably arranged between the two sets of tracks. The movable plate is used to support the funnel. At the same time, a spring and a guide rod are connected to the top of the movable plate. The guide rod is slidably connected to the positioning plate, thereby ensuring that the funnel can follow the movable plate to reciprocate up and down in the two sets of tracks, thereby preventing small and light nuts from causing obstruction in the funnel and hindering the subsequent nut from falling.
[0020] 3. This mobile phone nut mechanical pickup assembly has a first eccentric wheel installed at one end of a support shaft. The first eccentric wheel has a limit groove. A push rod is connected to the bottom of a moving plate, and a ball head is connected to the bottom end of the push rod. The ball head is positioned in the limit groove by utilizing the gap. Since the first eccentric wheel is set as an eccentric structure, the moving plate and the funnel on one side of the moving plate can be vertically raised while the first eccentric wheel rotates. When the first eccentric wheel rotates to the low position, the spring pushes the funnel downward, thereby causing the funnel to fall. This satisfies the vertical lifting and lowering drive of the funnel and meets the requirement of the nut falling smoothly.
[0021] 4. This mobile phone nut mechanical pickup assembly includes a traction component with a support shaft and a traction rope wound on the support shaft. The traction rope drives a first eccentric wheel and a second eccentric wheel. The first eccentric wheel drives the funnel to vertically reciprocate up and down, and the second eccentric wheel pushes the top block, causing the receiving tray to sway to a certain extent in an inclined state, thereby meeting the requirement of the nut falling smoothly.

Detailed Implementation
[0032] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0033] Example 1, please refer to Figures 1 to 9 The present invention discloses a mechanical picking component for mobile phone nuts, including a cabinet 1, a bracket 2 installed on the top of the cabinet 1, a camera 3 installed on the bracket 2, a movable picker 6 installed inside the cabinet 1, and a receiving tray 5 installed below the picker 6.
[0034] In this embodiment, a cabinet 1 is provided, and a data acquisition camera 3 is connected to the cabinet 1 via a bracket 2. The data acquisition camera 3 is a detection CCD camera. The data acquisition camera 3 is used to acquire the nuts located on the receiving tray 5. The receiving tray 5 is a flexible vibrating plate structure. Then, the nuts are placed on the nut carrier by the pickup 6. A data acquisition camera 3 is also provided on one side of the pickup 6. The detection CCD moves above each nut to confirm whether there are any missing, reversed, or stacked nuts.
[0035] It also includes a hopper 4 for feeding materials, which is slidably disposed on the inner wall of the cabinet 1, and a receiving tray 5 is disposed below the hopper 4.
[0036] In this embodiment, the funnel 4 and the cabinet 1 are connected, and the funnel 4 is set to be flat and connected in a sloping manner. This allows for manual online replenishment of the nut hopper without stopping the equipment and without opening the safety door of the equipment.
[0037] The cabinet 1 is equipped with two sets of vertically arranged mobile racks 8. One set of mobile racks 8 is connected to a stand 7 on one side, and the pickup 6 is installed on one side of the stand 7. The other set of mobile racks 8 is installed on one side of the aforementioned mobile racks 8.
[0038] In this embodiment, two sets of movable frames 8 are provided. One set of movable frames 8 is arranged in the horizontal X direction, and the other set of movable frames 8 is arranged in the horizontal Y direction, so that the movable frames 8 can drive the upright frame 7 and the pickup 6 to move as far as possible above the receiving tray 5.
[0039] Example 2 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 9 A movable plate 10 is connected to one side of the funnel 4. Two sets of rails 9 are symmetrically installed on one side of the inner wall of the cabinet 1. The movable plate 10 is slidably connected between the two sets of rails 9. A guide rod 13 is connected to the top of the movable plate 10. A positioning plate 12 is provided on one side of the inner wall of the cabinet 1. One end of the guide rod 13 is slidably connected to the positioning plate 12. A spring 11 is connected between the positioning plate 12 and the movable plate 10. The spring 11 is sleeved on the outside of the guide rod 13.
[0040] In this embodiment, two sets of tracks 9 are symmetrically arranged on the inner wall of the cabinet 1. A movable plate 10 is slidably arranged between the two sets of tracks 9. The funnel 4 is connected to one side of the movable plate 10. A spring 11 and a guide rod 13 are connected to the top of the movable plate 10. The spring 11 is sleeved on the outside of the guide rod 13. The guide rod 13 is slidably connected to the positioning plate 12, thereby ensuring that the funnel 4 can follow the movable plate 10 to move up and down in the two sets of tracks 9, thereby preventing smaller and lighter nuts from causing obstruction in the funnel 4 and hindering the subsequent nut from falling.
[0041] The receiving tray 5 is movably installed inside the cabinet 1. During the movement of the pickup 6, the funnel 4 can be driven to reciprocate up and down through the traction component. The traction component includes a support shaft 20 rotatably installed on the inner wall of the cabinet 1. A traction rope 22 is keyed to the surface of the support shaft 20. One end of the traction rope 22 is wrapped around the surface of the bushing 21, and the other end of the traction rope 22 is fixedly connected to one side of the upright frame 7. A first eccentric wheel 17 is fixedly installed on the surface of the support shaft 20 below the moving plate 10. An extension plate 14 is installed at the bottom of the moving plate 10. A top rod 15 is connected to the bottom surface of the extension plate 14. A ball head 16 is provided at the bottom end of the top rod 15. A limiting groove matching the ball head 16 is opened in the first eccentric wheel 17. Bearing seats 18 are provided at both ends of the support shaft 20. The bearing seats 18 are fixedly installed on the inner wall of the cabinet 1, and torsion springs 19 are provided at both ends of the bearing seats 18 and the support shaft 20.
[0042] In this embodiment, a traction assembly is provided between the pickup 6 and the funnel 4. The traction assembly includes a support shaft 20, which is rotatably mounted on the inner wall of one side of the cabinet 1. A bushing 21 is installed at one end of the surface of the support shaft 20, and a traction rope 22 is wound around the surface of the bushing 21. The end of the traction rope 22 away from the support shaft 20 is connected to one side of the stand 7. During the movement of the stand 7, the traction rope 22 can be pulled. When the traction rope 22 is pulled, it will pull the support shaft 20 to rotate.
[0043] A first eccentric wheel 17 is installed at one end of the support shaft 20. A limiting groove is formed in the first eccentric wheel 17. A push rod 15 is connected to the bottom of the moving plate 10. A ball head 16 is connected to the bottom end of the push rod 15. The ball head 16 is set in the limiting groove with a gap. Since the first eccentric wheel 17 is set as an eccentric structure, the moving plate 10 and the funnel 4 on one side of the moving plate 10 can be vertically raised while the first eccentric wheel 17 rotates. When the first eccentric wheel 17 rotates to the low position, the spring 11 pushes the funnel 4 downward, so that the funnel 4 falls. Finally, the vertical lifting and lowering of the funnel 4 is satisfied, which satisfies the requirement of the nut falling smoothly.
[0044] Example 3 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 9 Inside the cabinet 1, below the receiving tray 5, there are two sets of supports 23. The supports 23 and the receiving tray 5 are pinned together. The receiving tray 5 is set at an angle. Two sets of connecting blocks 24 are symmetrically arranged on the bottom surface of the receiving tray 5. Double-ear supports 25 are connected to the supports 23. The connecting blocks 24 and the double-ear supports 25 are pinned together. One side of one set of supports 23 is provided with two sets of second eccentric wheels 26. The second eccentric wheels 26 have annular grooves 27. One end of the traction rope 22 is wrapped around the two sets of annular grooves 27.
[0045] In this embodiment, two sets of supports 23 are provided below the receiving tray 5. The supports 23 and the receiving tray 5 are connected by connecting block 24 and double-ear support 25 in sequence. In addition to the inclined setting of the receiving tray 5, the pin connection structure can make the receiving tray 5 move and shake, which can further prevent the nuts from accumulating on one side of the receiving tray 5 after falling through the funnel 4, affecting the detection of nuts by the detection CCD and the gripping of nuts by the pickup 6.
[0046] Example 4 is an explanation based on Example 1. For details, please refer to [link / reference]. Figures 1 to 9 During the movement of the pickup 6, the receiving tray 5 can be driven to reciprocate horizontally by the traction component. A plate 29 is connected to one side of the receiving tray 5, and a top block 33 is connected above the plate 29. One end of the top block 33 has an inclined surface. A connecting plate 28 is provided on one side of the receiving tray 5. A lever 32 is connected to the top of the second eccentric wheel 26. A lever 30 is slidably connected to one side of the plate 29. A groove 31 is provided in the lever 30. The top of the lever 32 extends into the groove 31, and the groove 31 and the lever 32 are fitted with a clearance.
[0047] In this embodiment, a traction rope 22 is wound around the surface of the second eccentric wheel 26. As the traction rope 22 moves, it drives the second eccentric wheel 26 to rotate. The second eccentric wheel 26 is rotatably connected to one side of the support 23. A lever 32 is provided on the upper surface of the second eccentric wheel 26. Simultaneously, an insert plate 29 is connected to one side of the receiving tray 5 via a connecting plate 28. A lever block 30 is slidably connected to one side of the insert plate 29. A lever groove 31 is formed on one side of the lever block 30, and the lever 32 extends into the lever groove 31. The lever groove 31 follows the movement of the second eccentric wheel 26. The rotating mechanism moves the lever 30, which in turn moves the lever 30. When the lever 30 moves to the top block 33, it pushes the top block 33 along the inclined surface at one end of the top block 33. The top block 33 then moves the receiving tray 5. As the second eccentric wheel 26 rotates, the receiving tray 5 is pulled back to its original position. The movement of the pickup 6 pulls the traction rope 22, thereby causing the receiving tray 5 to shake. This allows the nut to move to the required position on the receiving tray 5, enabling the detection CCD to accurately detect the state of the nut and also enabling the pickup 6 to accurately pick up the nut.
[0048] It should be noted that in the structure where the traction rope 22 is wound around the second eccentric wheel 26, it can be wound at least two turns around the annular groove 27 to prevent the traction rope 22 and the second eccentric wheel 26 from disengaging. The moving frame 8 will not interfere with other structures under traction in the X and Y directions.
[0049] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, goods, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, goods, or apparatus.
[0050] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
