Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below in conjunction with specific embodiments and corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0018] The following is in conjunction with the appendix Figure 1-8 The technical solutions provided by the various embodiments of the present invention are described in detail below.

[0019] This invention provides an automatic feeding and riveting device for computer chassis accessories, including a workbench 1, a riveting table 2, and a riveting machine 3 arranged sequentially. The riveting table 2 is located below the riveting machine 3. The top of the workbench 1 is provided with two sets of rivet feeding mechanisms 4, which are symmetrically arranged on the top of the workbench 1. Each set of rivet feeding mechanisms 4 includes a rivet picking component 41 and two rivet feeding components 42. The rivet picking component 41 is located on the top of the workbench 1, and the two rivet feeding components 42 are symmetrically arranged at both ends of the rivet picking component 41. A riveting conveying component 5 is provided between the workbench 1 and the riveting table 2.

[0020] Two symmetrically arranged rivet feeding mechanisms 4 synchronously complete the automatic sorting, conveying, and storage of rivets for later use. The rivet picking component 41 accurately picks up the rivets to be processed, and the riveting and conveying component 5 automatically conveys the computer chassis parts to be processed to the riveting station. Finally, in conjunction with the riveting table 2 and the riveting machine 3, the precise alignment and riveting operation is completed. The entire process realizes the automated closed-loop operation of rivet feeding, workpiece conveying, and precise riveting, replacing the traditional manual loading, unloading, rivet placement, and alignment riveting operation mode.

[0021] This equipment features a fully automated integrated structure design, eliminating the need for manual intervention throughout the entire operation, significantly reducing the number of employees and lowering labor costs for enterprises. At the same time, the seamless connection between each process solves the problems of poor process connection and cumbersome debugging in traditional equipment. It can quickly adapt to the production needs of riveting chassis parts of various varieties and small batches, breaking through the upgrade bottleneck of traditional production mode and achieving a dual improvement in production efficiency and product yield.

[0022] In a specific embodiment, the rivet material picking assembly 41 includes an automatic material picking robot arm 411 and an installation plate 412. The automatic material picking robot arm 411 is located on the top of the workbench 1, and the installation plate 412 is located on the moving end of the automatic material picking robot arm 411. The installation plate 412 is provided with three equally spaced gripping air clamps 413.

[0023] During operation, the automatic material handling robotic arm 411 performs multi-dimensional displacement adjustment based on a preset program, driving the installation plate 412 at the mobile end to move precisely to the storage position of the feeding component. Three equally spaced gripping pneumatic clamps 413 on the installation plate 412 work synchronously, accurately gripping the neatly finished rivets, and can simultaneously grip multiple rivets at a time. After gripping, the robotic arm accurately moves to the workpiece to be riveted, accurately releases the rivets, and completes the entire process of automatic rivet material handling, transfer, and alignment, with precise positioning throughout the entire process according to the preset program.

[0024] This component utilizes an automated structure design consisting of an automatic material-grabbing robotic arm 411 and multi-station pneumatic grippers 413 to replace manual material handling and alignment. The three equally spaced pneumatic grippers 413 enable batch material handling, significantly improving material handling efficiency and adapting to mass production needs. The robotic arm's programmed precise positioning achieves a positioning accuracy far exceeding that of manual operation, completely eliminating manual alignment deviations and fundamentally avoiding quality issues such as misaligned riveting and incomplete riveting, greatly improving the riveting accuracy and consistency of the product. Simultaneously, the entire material handling process is fully automated, eliminating the need for close-range human contact with the riveting station, completely avoiding the safety hazards of close-range human operation, and significantly reducing the labor intensity of operators.

[0025] In a specific embodiment, each rivet feeding assembly 42 includes a support frame 420, a vibrating feeding plate 421, a rivet conveying track 422, a mounting base 423, a drive motor 424, a vibrating plate 425, and a material holding seat 426. The support frame 420 is located on top of the workbench 1, the vibrating feeding plate 421 is located on top of the support frame 420, the mounting base 423 is located beside the support frame 420, the drive motor 424 is located inside the mounting base 423, the material holding seat 426 is located on top of the mounting base 423, the vibrating plate 425 is horizontally rotatably connected to the material holding seat 426, the bottom of the vibrating plate 425 is connected to the main shaft of the drive motor 424, the rivet conveying track 422 is connected between the vibrating feeding plate 421 and the vibrating plate 425, and a support base 427 is provided at the bottom of the rivet conveying track 422.

[0026] In a specific embodiment, the vibratory feeder 425 has a material holding cavity 428 for holding rivets. The rotary vibratory feeder 425, in conjunction with the independent material holding cavity 428, can accurately hold a fixed number of rivets in a fixed posture, ensuring that the rivets are handled uniformly each time, further improving the accuracy of subsequent riveting operations. During operation, the vibrating feeder 421 uses high-frequency vibration to automatically sort, sequence, and directionally convey disordered rivets, sending rivets with uniform posture into the rivet conveying track 422 in an orderly manner. The rivet conveying track 422 maintains a stable conveying state under the support of the bottom support seat 427, smoothly conveying the rivets into the vibrating plate 425. The drive motor 424 drives the vibrating plate 425 to rotate horizontally inside the holding seat 426 through the main shaft. The holding cavity 428 inside the vibrating plate 425 is used to collect and organize the rivets at fixed points. The rivet station switching is realized by rotation adjustment, so that the rivets to be picked up are always in the precise gripping area of ​​the gripping air clamp 413, continuously providing the picking component with rivets with uniform posture and fixed position to be processed, realizing the entire process of automated sorting, conveying, storage, and preparation of rivets.

[0027] This component integrates vibration sorting, track conveying, and rotary storage into a single structure, enabling fully automated and continuous rivet sorting and feeding without the need for manual sorting and replenishment, significantly reducing human intervention and labor costs. The support base 427 provides stable support for the rivet conveying track 422, preventing material conveying deviation and jamming, and ensuring feeding stability. At the same time, the modular integrated structure design is compact and highly integrated, making it convenient for model switching and debugging. It can adapt to the production needs of different specifications of rivets and chassis accessories, solving the pain points of low integration, poor adaptability, and long debugging time of traditional equipment.

[0028] In a specific embodiment, the riveting conveying assembly 5 includes a support platform 51, a horizontal plate 52, a conveying motor 53, a conveying screw shaft 54, a conveying block 55, and a conveying table 56. The support platform 51 is located between two support frames 420, and the horizontal plate 52 is located between the support platform 51 and the riveting table 2. The horizontal plate 52 is provided with two symmetrically arranged conveying slide rails 57. The conveying motor 53 is located on the horizontal plate 52. The conveying screw shaft 54 ​​is horizontally rotatably connected inside the horizontal plate 52 and is connected to the main shaft of the conveying motor 53. The conveying block 55 is located at the bottom of the conveying table 56 and is threadedly connected to the conveying screw shaft 54. The bottom of the conveying table 56 is provided with two conveying slide seats 560, and the two conveying slide seats 560 are slidably engaged with the two conveying slide rails 57 respectively.

[0029] During operation, the operator places the computer case components on the workpiece placement position 59 of the conveyor plate 56. After the equipment is started, the conveyor motor 53 drives the conveyor screw shaft 54 ​​to rotate. Through the threaded transmission structure of the conveyor screw shaft 54, the conveyor block 55 and the conveyor plate 56 are moved horizontally. The workpiece placement position 59 at the bottom of the conveyor plate 56 forms a sliding fit with the conveyor slide rail 57 on the horizontal plate 52, which precisely guides the displacement of the conveyor plate 56, ensuring that the workpiece is conveyed smoothly and without deviation. When the conveyor plate 56 moves the workpiece to the riveting station 2, the proximity switch 58 at the end of the conveyor slide rail 57 senses the positioning signal, provides real-time feedback, and controls the conveyor motor 53 to stop, thereby achieving precise workpiece positioning and completing the workpiece automatic conveying and precise alignment operation. After riveting is completed, the conveyor motor 53 reverses to drive the workpiece to reset, completing a single operation cycle.

[0030] This component adopts an automated conveying structure with a lead screw shaft 54 ​​for transmission and a guide rail 57 for guidance. It features smooth transmission and high positioning accuracy, enabling automated and rapid workpiece conveying and precise workstation alignment. This significantly improves workpiece conveying efficiency, standardizes production cycle time, and meets the needs of batch continuous production.

[0031] In a specific embodiment, a proximity switch 58 is provided at the end of the conveying slide rail 57 and above the riveting table 2, and the proximity switch 58 is electrically connected to the conveying motor 53.

[0032] When the conveyor plate 56 moves the workpiece precisely to the riveting station, the proximity switch 58 senses the workpiece's arrival signal and immediately transmits an electrical signal to the control system. The control system then immediately controls the conveyor motor 53 to stop running and locks the workpiece position. After the riveting operation is completed, the system receives the completion signal and controls the conveyor motor 53 to restart and reset, thus achieving automated and precise start-stop control.

[0033] In a specific embodiment, the top of the conveyor plate 56 is provided with two workpiece placement positions 59 for placing computer chassis accessories.

[0034] It can hold two chassis parts to be processed at the same time; the dual workpiece placement position 59 enables simultaneous processing of two workstations, effectively improving equipment production efficiency and adapting to batch production needs.

[0035] In a specific embodiment, the top of the conveying platform 56 is provided with four sets of support members 50, which are evenly distributed at both ends of the two conveying slide rails 57; each set of support members 50 includes a support frame 501, and the top of the support frame 501 is provided with three equally distributed support wheels 502.

[0036] After the computer chassis parts are conveyed to the riveting machine 3 via the conveyor plate 56, the multi-point support wheel 502 structure, compared with the fixed support structure, can avoid damage to the workpiece surface caused by hard extrusion. At the same time, it evenly distributes the riveting pressure, prevents deformation of thin-walled chassis parts, and ensures the appearance and structural accuracy of the product. The equidistant layout design is suitable for chassis parts of various specifications, further improving the versatility and adaptability of the equipment and meeting the needs of multi-variety production.

[0037] The above are merely embodiments of the present invention and are not intended to limit the invention. Various modifications and variations can be made to the present invention by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principle of the present invention should be included within the scope of the claims of the present invention.
