[0027] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0028] It should be noted that the terms "first," "second," etc., used in this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this disclosure described herein can be implemented in orders other than those illustrated or described herein. The implementation methods described in the following exemplary embodiments do not represent all implementation methods consistent with this disclosure.

[0029] Please see Figures 1-16In this embodiment of the utility model, an automatic feeding device for irregularly shaped copper busbars and hardware parts includes a frame 1; the frame 1 is equipped with: a nut conveying vibratory feeder 2, which arranges and conveys nuts in an orderly manner; a steel sleeve conveying vibratory feeder 3, which arranges and conveys steel sleeves in an orderly manner; a plastic part conveying vibratory feeder 4, which arranges and conveys plastic parts in an orderly manner; a copper busbar feeding mechanism 5, which arranges and conveys copper busbars in an orderly manner; a nut and plastic part riveting mechanism 6, which rivets the conveyed nuts and plastic parts to form a nut and plastic part assembly; a secondary positioning mechanism 7, which performs secondary positioning on the nut and plastic part assembly and the copper busbar to meet subsequent processing requirements; a steel sleeve dispensing mechanism 63, which dispenses the steel sleeves conveyed by the steel sleeve conveying vibratory feeder 3; and a robotic gripping mechanism 8, which transports the dispensed steel sleeves, the nut and plastic part assembly after secondary positioning, and the copper busbar to an injection molding machine 64 for molding.

[0030] Specifically, this automatic feeding equipment for irregularly shaped copper busbars and hardware parts integrates multiple automated feeding and pre-processing units, aiming to achieve efficient collaborative conveying and pre-processing of various parts such as copper busbars, nuts, steel sleeves, and plastic parts. The entire system utilizes multiple independent vibratory feeder systems to arrange and continuously convey different types of hardware or plastic parts in an orderly manner, ensuring the orderliness and consistency of materials before entering subsequent processes. Nuts and plastic parts are pre-assembled using a riveting mechanism to form a stable assembly, which helps improve assembly accuracy and the consistency of the injection-molded product. After initial assembly, a secondary positioning mechanism 7 is introduced to precisely calibrate the nut-plastic part assembly and the copper busbar, ensuring their spatial alignment and stability, laying the foundation for subsequent injection molding. The steel sleeve distribution mechanism 63 divides the steel sleeves conveyed by the steel sleeve conveying vibratory feeder 3 into several conveying routes, allowing the subsequent robotic gripper mechanism 8 to simultaneously grip and convey multiple steel sleeves. Driven by a multi-axis robotic arm 65, the robotic gripper mechanism 8 plays a crucial role in this process, enabling automatic gripping and precise placement of steel sleeves, copper busbars, and assemblies, effectively connecting various sub-modules and improving overall cycle efficiency. The equipment features a compact overall structure and clearly defined functional modules, significantly reducing manual operation and improving production efficiency and assembly quality. It is particularly suitable for batch processing of irregularly shaped copper busbar products.

[0031] Furthermore, the nut plastic part riveting mechanism 6 includes a riveting mechanism mounting frame 9; a horizontally arranged linear feeder 10 on the riveting mechanism mounting frame 9; the inlet of the linear feeder 10 is connected to the outlet of the plastic part conveying vibratory plate 4; a plastic part guide trough block 11 is provided at the outlet of the linear feeder 10, which is vertically arranged with respect to the linear feeder 10; the plastic part guide trough block 11 is connected to the outlet of the plastic part conveying vibratory plate 4; a first pushing cylinder 12 is provided to push the plastic part inside the guide trough block forward; a riveting cylinder 13 with a piston rod facing downward is provided at the top of the plastic part guide trough block 11; a riveting head 14 is connected to the piston rod of the riveting cylinder 13; a plastic part outlet is provided at the bottom of the plastic part guide trough block 11; the riveting head 14 is connected to the plastic part outlet; and a nut guide trough block 15 is provided to guide the nut. The top of the flow channel block 15 has a nut inlet for the nut to enter; the outlet of the nut conveying vibratory plate 2 is connected to the inlet of the nut guide channel block 15; and a second pushing cylinder 16 is provided to push the nut inside the nut guide channel block 15 forward; and a rotary cylinder 17 is also provided on the riveting mechanism mounting frame 9; and the rotary cylinder 17 is connected to a riveting table 18 that rotates synchronously with it; and a number of riveting slots 19 are formed on the riveting table 18; firstly, the nut is conveyed to the riveting slots 19 of the riveting table 18 by the nut conveying vibratory plate 2, the nut guide channel block 15, and the first pushing cylinder 12, and then the plastic part is conveyed to the riveting slots 19 by the plastic part conveying vibratory plate 4, the linear feeder 10, the plastic part guide channel block 11, and the second pushing cylinder 16. Then, the riveting cylinder 13 drives the riveting head 14 to press down, so that the plastic part is riveted to the nut.

[0032] Specifically, the riveting mechanism mounting frame 9 serves as a support platform, upon which all sub-components are integrated, enabling modular installation and convenient debugging. A horizontally arranged linear feeder 10 is installed along the conveying path of the plastic parts. Its inlet connects to the plastic parts vibratory feeder, ensuring the orderly linear advancement of the plastic parts. A vertical plastic parts guide trough 11 is installed at its outlet, which, combined with the first pusher cylinder 12, achieves precise vertical pushing, ensuring the plastic parts are accurately positioned in the subsequent riveting area, guaranteeing the workpiece's posture and stability. For the nut conveying path, a nut guide trough 15 and a second pusher cylinder 16 are installed, similarly achieving stable conveying from the vibratory feeder to the riveting position. The nuts and plastic parts, through their independent guide paths and pusher mechanisms, are ultimately synchronously positioned in the riveting slots 19 on the riveting table 18. The riveting table 18 is driven by a rotary cylinder 17, enabling cyclical operation of multiple riveting stations, thereby improving equipment cycle efficiency. Multiple riveting slots 19 on the riveting table 18 are sequentially positioned directly below the riveting cylinder 13 under the action of the rotary cylinder 17, enabling continuous operation. The piston rod of the riveting cylinder 13 is set downwards, and when pressed down, it drives the riveting head 14 to complete the riveting action between the nut and the plastic part. The whole process is fast, stable, and highly precise.

[0033] Furthermore, a positioning cylinder 20 with its piston rod facing upward is provided below the riveting table 18; and the piston rod of the positioning cylinder 20 is connected to a positioning rod 21; during riveting, the positioning cylinder 20 drives the positioning rod 21 to extend, so that the positioning rod 21 is inserted into the hole of the nut to limit the nut; after the riveting is completed, the positioning cylinder 20 drives the positioning rod 21 to reset.

[0034] Specifically, this structure incorporates a coordinated limiting design of a positioning cylinder 20 and a positioning rod 21 during the riveting process between the nut and the plastic part, further enhancing riveting accuracy and stability. The positioning cylinder 20, located below the riveting table 18, has its piston rod facing upwards. It extends into the hole of the nut via the connected positioning rod 21, providing precise positioning and effectively preventing misalignment or poor riveting due to uneven force, offset, or rotation of the nut during riveting. Especially during riveting, when the riveting head 14 applies significant downward pressure to the plastic part, the nut is prone to slippage or tilting if not effectively restrained, thus affecting the riveting quality. The positioning rod 21 cleverly utilizes the nut's structural feature—the through hole in the middle—as a positioning reference. Through insertion, it achieves dual positioning control of the nut in both the horizontal and vertical directions, ensuring its axis is aligned with the riveting head 14, improving the consistency and repeatability of the riveting process. In addition, after riveting is completed, the positioning cylinder 20 can quickly reset and retract the positioning rod 21 to avoid interfering with the rotation of the riveting table 18, ensuring that the whole system has a smooth rhythm and a high degree of automation.

[0035] Furthermore, the secondary positioning mechanism 7 includes a first linear module 23 and a second linear module 24; the first linear module 23 is equipped with a side posture cylinder 25 that reciprocates linearly with it; the side posture mounting block of the side posture cylinder 25 is connected to a lifting cylinder 26; and the piston rod of the lifting cylinder 26 is connected to a positioning platform 27; the positioning platform 27 has a plurality of positioning holes 28 formed thereon for placing and positioning the nut plastic part assembly and the copper busbar; the second linear module 24 is equipped with a slide cylinder 29 that reciprocates synchronously with it; and the slide cylinder 29 is equipped with a finger cylinder 30 that slides up and down synchronously with it; the second linear module 24 and the slide cylinder 29 drive the finger cylinder 30 to move, thereby placing the nut plastic part assembly that has been riveted on the riveting table 18 onto the positioning holes 28 of the positioning platform 27.

[0036] Specifically, the mechanism consists of two linear modules, which control the horizontal and vertical movements respectively, forming the core drive framework for three-dimensional spatial positioning. The first linear module 23 is equipped with a side-positioning cylinder 25 that reciprocates synchronously. This cylinder drives the lifting cylinder 26 and positioning platform 27 mounted on the side-positioning mounting block to rotate 90 degrees, facilitating the subsequent gripping mechanism 8 to grasp the copper busbar and nut plastic assembly after secondary positioning. The positioning platform 27 has several pre-set positioning holes 28, specifically for placing and positioning the riveted nut plastic assembly and copper busbar, ensuring they maintain a fixed posture and positional accuracy during subsequent processing or molding, thus ensuring the consistency and controllability of the overall assembly. The second linear module 24 is designed primarily to transfer the material from the riveting platform 18 to the positioning platform 27. The sliding cylinder 29 mounted on it is responsible for lateral movement and drives the finger cylinder 30 connected to it to slide up and down, thereby completing a standard handling process similar to "gripping—lifting—moving—placing". The finger cylinder 30 precisely grasps the assembly on the riveting table 18 through the opening and closing action of the claw and smoothly transfers it to the corresponding hole in the positioning table 27. Throughout the operation, the two linear modules work together to achieve precise control in multiple degrees of freedom, effectively overcoming the error accumulation problem in the multi-process connection of traditional equipment; the first linear module 23 and the second linear module 24 can be directly purchased from existing commercially available motor screw driven linear modules.

[0037] Furthermore, the robotic gripping mechanism 8 includes a fixedly mounted base plate 31; a cylinder mounting bracket 32 ​​is provided on the base plate 31; a telescopic cylinder 33 is provided on the cylinder mounting bracket 32; and the piston rod of the telescopic cylinder 33 is connected to a part-grabbing cylinder mounting plate 34; the part-grabbing cylinder mounting plate 34 is provided with a plurality of first part-grabbing cylinders 35 for picking up nut plastic parts; a plurality of second part-grabbing cylinders 36 for picking up copper busbars; and a plurality of third part-grabbing cylinders 37 for picking up steel sleeves; and a first ejector pin mounting plate 3 is fixedly provided between the base plate 31 and the cylinder mounting bracket 32. 8; and the first ejector plate 38 is equipped with a plurality of first ejector pins 39 that slide with the first picking cylinder 35; a plurality of second ejector pins 40 that are fixedly connected to the first ejector plate 38; and a plurality of third ejector pins 41 that slide with the third picking cylinder 37; the picking cylinder mounting plate 34 is extended by the telescopic cylinder 33, thereby driving the first picking cylinder 35, the second picking cylinder 36, and the third picking cylinder 37 to pick up parts; after picking up parts, the picking cylinder mounting plate 34 is retracted by the telescopic cylinder 33, thereby causing the first ejector pins 39, the second ejector pins 40, and the third ejector pins 41 to extend and detach the picked-up parts.

[0038] Specifically, the robotic gripper mechanism 8 achieves efficient and flexible gripping and release of different types of workpieces through a precise combination of pneumatic and mechanical structures. Its core components include a base plate 31 fixed to the frame 1, on which a cylinder mounting bracket 32 ​​is mounted. The cylinder mounting bracket 32 ​​supports a telescopic cylinder 33 capable of retractable movement. The piston rod of the telescopic cylinder 33 is connected to a part-grabbing cylinder mounting plate 34, which is equipped with multiple sets of functionally distinct part-grabbing cylinders: the first part-grabbing cylinder 35 is specifically used for gripping assemblies of nuts and plastic parts, the second part-grabbing cylinder 36 is used for gripping copper busbars, and the third part-grabbing cylinder 37 is responsible for gripping steel sleeves. This multi-part-grabbing cylinder design significantly improves the robotic arm's compatibility with irregularly shaped and multi-type workpieces, meeting the diverse needs of complex production environments. A first ejector pin mounting plate 38 is located between the base plate 31 and the mounting bracket. The first, second, and third ejector pins 41 mounted on this plate slide in cooperation with their corresponding part-grabbing cylinders, forming a complete gripping and release coordination mechanism. During the gripping process, the telescopic cylinder 33 drives the part-grabbing cylinder mounting plate 34 to extend forward, enabling various part-grabbing cylinders to accurately cover and clamp the target workpiece, achieving stable gripping. After the part is picked up, the cylinder drives the mounting plate to retract, and in conjunction with the extension of the ejector pin, the ejector pin pushes the workpiece away from the part-grabbing cylinder, achieving precise product release. The overall design, through the telescopic control of the cylinder and the mechanical assistance of the ejector pin, ensures the efficiency, reliability, and repeatability of the gripping and placement process, providing a solid guarantee for continuous automated operation of the production line, and is particularly suitable for complex automated assembly scenarios of irregularly shaped copper busbars and various hardware parts.

[0039] Furthermore, a first suction nozzle mounting plate 42 and a second suction nozzle mounting plate 43 are provided at intervals on one side of the substrate 31; and a plurality of suction nozzle heads 44 are provided on both the first suction nozzle mounting plate 42 and the second suction nozzle mounting plate 43; the robotic gripping mechanism 8 drives the suction nozzle heads 44 to move, and places the copper busbar from the copper busbar feeding mechanism 5 onto the secondary positioning mechanism 7 for secondary positioning.

[0040] Specifically, the robotic gripping mechanism 8 has a first suction nozzle mounting plate 42 and a second suction nozzle mounting plate 43 arranged at intervals on one side of the base plate 31. Both mounting plates are equipped with several suction nozzles 44, forming a highly efficient vacuum suction system. Through the coordinated movement of the robotic arm, the suction nozzles 44 can accurately and stably grip the copper busbars, achieving smooth transport and placement from the copper busbar feeding mechanism 5 to the secondary positioning mechanism 7. The multi-point layout design of the suction nozzles not only improves the coverage of the gripping surface for irregularly shaped copper busbars, enhancing the stability and safety of the gripping, but also effectively prevents the copper busbars from shaking and slipping during movement, ensuring the accuracy of subsequent secondary positioning. This system uses vacuum adsorption technology to replace traditional mechanical clamps, greatly reducing the risk of mechanical damage to the surface of the copper busbars, while improving gripping speed and response sensitivity. The reasonable distribution of the suction nozzle mounting plates, combined with the flexible operation of the robotic arm, achieves flexible handling under complex paths, meeting the automated transport needs of the production line for copper busbars of various specifications and shapes.

[0041] Furthermore, the steel sleeve distribution mechanism includes a front plate 45 and a rear plate 46 corresponding to the front plate 45; the inner wall of the rear plate 46 is formed with several distribution grooves 47 at intervals; the top of both the front plate 45 and the rear plate 46 is formed with a steel sleeve inlet 48; the steel sleeve inlet 48 is connected to each distribution groove 47; and the bottom of the front plate 45 is formed with several steel sleeve outlets 49 connected to the distribution grooves 47; the steel sleeve enters each distribution groove 47 from the steel sleeve inlet 48 and reaches the steel sleeve outlet 49 along the distribution groove 47; and an ejector cylinder 50 is provided at the rear of the rear plate 46; the piston rod of the ejector cylinder 50 is connected to a second ejector pin mounting plate 51; and several fourth ejector pins 52 are provided on the second ejector pin mounting plate 51; and the steel sleeve is ejected by passing through the rear plate 46 and the steel sleeve outlet 49 via the fourth ejector pins 52.

[0042] Specifically, the steel sleeve distribution mechanism, through the coordinated design of the front plate 45 and the rear plate 46, achieves orderly diversion and precise conveying of steel sleeves from the inlet to the outlet. Both the front and rear plates 46 have steel sleeve inlets 48 at their tops, forming a large inlet; ensuring that the steel sleeves can smoothly enter each distribution groove 47. Several distribution grooves 47, spaced apart on the inner wall of the rear plate 46, provide a clear guiding path for the steel sleeves, allowing them to slide smoothly along a predetermined trajectory, avoiding accumulation and congestion. The steel sleeve outlet 49, penetrating the bottom of the distribution groove 47, connects to the distribution groove 47, forming a channel for sequential output of steel sleeves, ensuring the continuous supply of steel sleeves to downstream processes. At the rear of the mechanism is an ejector cylinder 50, whose piston rod is connected to a second ejector mounting plate 51. Multiple fourth ejector pins 52 arranged on the mounting plate precisely pass through the rear plate 46 and the steel sleeve outlet 49, completing the ejection action of the steel sleeves. The ejector cylinder 50, in conjunction with the ejector pin, pneumatically drives the rapid pushing of the steel sleeve, forcefully pushing it out of the distribution trough 47. This ensures the steel sleeve is delivered promptly and accurately to subsequent material handling or assembly positions. This design not only automates the distribution and conveying of steel sleeves but also ensures the stability and efficiency of the distribution process through pneumatic ejection, preventing steel sleeve jamming or obstructed conveying, and greatly improving the overall smoothness of the production line and the reliability of the equipment.

[0043] Furthermore, the copper busbar feeding mechanism 5 includes a first servo motor 53 with its shaft facing upward; and the shaft of the first servo motor 53 is connected to a support plate 54; and the support plate 54 is provided with several sets of copper busbar placement stations 55; and a servo lifting mechanism is provided below the support plate 54; and the servo lifting mechanism is connected to several fifth pins 56 to gradually lift the copper busbar.

[0044] Specifically, the power source is a first servo motor 53 positioned upwards, which directly drives the upper support plate 54 to rotate via its shaft. Multiple copper busbar placement stations 55 are arranged on the support plate 54, allowing for sequential rotation and positioning of multiple stations according to preset angle intervals during operation, forming a turntable-like feeding structure. This design not only saves space but also facilitates the simultaneous pre-installation of multiple copper busbars, significantly improving material changing efficiency and system continuity. A servo lifting mechanism is located below the support plate 54, which, through multiple fifth ejector pins 56 connected to it, individually lifts copper busbars at specific stations, enabling the target copper busbar to be pushed to a height where it can be grasped by a suction nozzle or robotic arm after reaching the designated position.

[0045] Furthermore, the servo lifting mechanism includes a first lifting mechanism mounting plate 57 and a second lifting mechanism mounting plate 58 spaced apart; a motor mounting bracket 59 is provided below the second lifting mechanism mounting plate 58; a second servo motor 60 with its rotating shaft facing upward is provided on the motor mounting bracket 59; and a guide rod 61 is provided between the first lifting mechanism mounting plate 57 and the second lifting mechanism mounting plate 58; both ends of the guide rod 61 are fixedly connected to the first lifting mechanism mounting plate 57 and the motor mounting bracket 59 respectively; and the second lifting mechanism mounting plate 58 and the guide rod 61 slide vertically together; and the first A rotating rod 62 is provided between the lifting mechanism mounting plate 57 and the second lifting mechanism mounting plate 58; one end of the rotating rod 62 is connected to the shaft of the second servo motor 60, and the other end of the rotating rod 62 is rotatably connected to the first lifting mechanism mounting plate 57; the rotating rod 62 is threadedly connected to the second lifting mechanism mounting plate 58; and the fifth ejector pin 56 is mounted on the top of the second lifting mechanism mounting plate 58; the rotating rod 62 is driven to rotate by the second servo motor 60, so that the second lifting mechanism mounting plate 58 drives the sixth ejector pin to move up and down synchronously, thereby gradually lifting the copper busbar.

[0046] Specifically, the lifting mechanism consists of a main frame formed by a first lifting mechanism mounting plate 57 and a second lifting mechanism mounting plate 58 spaced apart, connected by a guide rod 61. The guide rod 61 not only provides structural support but also acts as a guiding element, ensuring the straightness and stability of the second lifting mechanism mounting plate 58 during vertical movement. A motor mounting bracket 59 is located at the bottom of the second mounting plate, on which a second servo motor 60 with its shaft facing upwards is mounted. This motor drives a rotating rod 62 connected to it at one end via its shaft. The other end of the rotating rod 62 is rotatably connected to the first lifting mechanism mounting plate 57, while its middle is linked to the second lifting mechanism mounting plate 58 via a threaded connection. This allows the motor's rotation angle to be converted into a linear lifting motion of the second mounting plate through the threaded advancement of the rotating rod 62. As the second mounting plate slides up and down, several vertical sixth pins fixed at the top move up and down synchronously. These pins can precisely lift the copper busbar placed above, achieving step-by-step lifting for subsequent workstations such as gripping devices or positioning mechanisms.
