Description

Technical Field

[0001] This utility model relates to the field of carbon fiber badminton racket production technology, and in particular to a carbon fiber badminton racket handle production line and its feeding unit. Background Technology

[0002] With the widespread application of carbon fiber composite material technology in the field of sports equipment, the market demand for high-performance carbon fiber badminton rackets is increasing. To improve product quality and production efficiency, automated production technology is being increasingly introduced into badminton racket assembly lines. These automated production lines typically involve multiple precision processes such as handle joining, nailing, and stringing, requiring extremely high standards for the coordination of each step and the stability of material supply. Against this backdrop, the handling methods used in the racket frame loading and handle joining stages, which are the starting point of the entire automated assembly process, directly affect the efficiency of the entire production line.

[0003] In existing technologies, some models have attempted to solve this problem. For example, Chinese utility model patent (authorization announcement number CN222173012U) discloses an automatic badminton racket handle attaching machine. This device aims to solve the problems of continuous handle attaching and the need for manual glue application. Its structure mainly includes two rotating disks (a first connecting disk and a second connecting disk) synchronously driven by servo motors, used for attaching the handle and limiting and fixing the badminton racket head, respectively. Through the rotating disk structure with four workstations, the device can perform handle attaching operations on one racket while the operator unloads finished products and loads products to be processed at other workstations, thus achieving continuous operation. In addition, the machine is equipped with a glue-applying roller brush between the two disks, which automatically applies glue as the racket shaft passes through the rotating disk, eliminating manual operation.

[0004] However, current processing methods and existing technologies still have shortcomings. Traditional manual feeding and handle connection methods are not only inefficient and lack positioning accuracy, but also labor-intensive. Even with the automated equipment described in the aforementioned patent (CN222173012U), although the handle connection and gluing processes are automated and continuous, the initial feeding step—placing the badminton racket frame and handle onto the corresponding stations on the rotating disk—still requires manual operation. This manual feeding step remains a bottleneck in the entire automated process, limiting further improvements in the production line's automation level and failing to completely eliminate the potential impact of the speed and stability of manual operation.

This stacked arrangement also buffers material, reducing the frequency of manual replenishment. The rotating feeding mechanism integrates several angled feeding rods on its bracket, upgrading a single feeding channel into a rotating, multi-station material bin, significantly increasing the equipment's single-batch material preparation capacity and buffering capacity. When all racket frames on one feeding rod are removed, the mechanism can quickly switch to the working position of another fully loaded feeding rod by rotation, supplying the guiding and unloading mechanisms. Simultaneously, operators can replenish empty feeding rods without stopping the equipment. This "production-while-replenishing" model enables continuous and uninterrupted production, minimizes downtime, and significantly improves the overall operating efficiency of the production line and the overall efficiency of the equipment.

[0038] To make the above-mentioned objects, features, and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0039] See Figure 1 This utility model provides a racket frame feeding unit for a carbon fiber badminton racket assembly line. The feeding unit is located at the first station of the assembly line and includes:

[0040] 100 racks;

[0041] The feeding mechanism includes a column 210 mounted on the frame 100 and a bracket 220 rotatably connected to the column 210. The bracket 220 includes a feeding rod 221 for suspending the racket frame. One end of the feeding rod 221 is provided with a baffle plate 222. The height of the end of the feeding rod 221 near the column 210 is higher than the height of the end connected to the baffle plate 222, so that the racket frame can be stacked along the feeding rod 221.

[0042] The guiding mechanism 300 includes a feeding baffle 310 and a feeding limiting block 320. The feeding baffle 310 is located at the discharge port and fixed on the frame 100, and can laterally limit the several frames on the feeding rod 221. The feeding limiting block 320 is located at the end of the feeding baffle 310 away from the column 210, and can longitudinally limit the frames that have moved to the feeding limiting block 320.

[0043] And a material handling mechanism 400 disposed on the frame 100, used to grab the frame that has moved to the loading limit block 320 and transport it to the receiving unit.

[0044] The racket frame feeding unit of the carbon fiber badminton racket assembly line provided in this embodiment aims to replace traditional manual feeding, thereby significantly improving the automation level and efficiency of the production line. Specifically, the feeding mechanism in this solution uses a hanger 220 rotatably connected to the column 210, and the feeding rod 221 is tilted with one end higher than the other. This cleverly utilizes gravitational potential energy, allowing multiple racket frames suspended on the rod to slide automatically and sequentially towards the lower end without additional power, achieving simple, low-cost, and reliable continuous feeding. At the same time, this stacked arrangement also serves to buffer materials, reducing the frequency of manual replenishment.

[0045] Based on this, the lateral limit provided by the loading baffle 310 and the longitudinal limit provided by the loading limit block 320 together form a positioning point, ensuring that each frame that slides to this point can be constrained in a fixed three-dimensional spatial position, ensuring the repeatability and consistency of the position, and providing a stable prerequisite for subsequent robotic arm grasping.

[0046] Finally, the material handling mechanism 400 is directly responsible for performing the grabbing and conveying actions. It will be grabbed by the frame positioned by the guide mechanism 300 and sent to the next receiving unit, replacing the manual picking and placing actions. This seamlessly connects the feeding process with the subsequent processes, forming a complete automated closed loop, thereby ensuring the stability of the production cycle and the consistency of product processing.

[0047] An embodiment of this utility model also provides a racket frame feeding unit for a carbon fiber badminton racket assembly line. The feeding unit is located at the first station of the assembly line and includes:

[0048] 100 racks;

[0049] The rotary feeding mechanism 200 includes a column 210 mounted on a frame 100 and a hanger 220 rotatably connected to the column 210. The hanger 220 includes a plurality of feeding rods 221 for suspending the frame. The feeding rods 221 are arranged at an angle to each other. One end of the feeding rod 221 is provided with a baffle plate 222. The height of the end of the feeding rod 221 near the column 210 is higher than the height of the end connected to the baffle plate 222, so that the frame can be stacked along the feeding rod 221.

[0050] The guiding mechanism 300 includes a feeding baffle 310 and a feeding limiting block 320. The feeding baffle 310 is located at the discharge port and fixed on the frame 100, and can laterally limit the several frames on the feeding rod 221. The feeding limiting block 320 is located at the end of the feeding baffle 310 away from the column 210, and can longitudinally limit the frames that have moved to the feeding limiting block 320.

[0051] And a material handling mechanism 400 disposed on the frame 100, used to grab the frame that has moved to the loading limit block 320 and transport it to the receiving unit.

[0052] This embodiment introduces a rotary feeding mechanism 200 based on the aforementioned automated feeding scheme. The mechanism's bracket 220 integrates several angled feeding rods 221, upgrading a single feeding channel into a rotary, multi-station material hopper, significantly increasing the equipment's single-batch material preparation capacity and material buffering capacity. When the rack of one feeding rod 221 is completely empty, the mechanism can rotate to quickly switch another fully loaded feeding rod 221 to the working position, supplying the guiding mechanism 300 and the material handling mechanism 400 to continue operation. Simultaneously, operators can replenish empty feeding rods 221 without stopping the equipment. This "production-while-replenishing" mode achieves continuous and uninterrupted production, minimizing downtime and significantly improving the overall operating efficiency and overall equipment efficiency (OEE) of the entire production line, making the automated production process smoother and more efficient.

[0053] See Figure 2In one embodiment, the hanger 220 further includes a base plate 223 and side plates 224. The side plates 224 are disposed on the base plate 223, and several side plates 224 are arranged at an angle to each other. A feeding rod base 225 is provided on the side plate 224 for mounting the feeding rod 221. In this embodiment, the hanger 220 of the rotating feeding mechanism 200, by adding the base plate 223 and side plates 224, together constitutes a supporting platform. The base plate 223 provides the basic rigidity and rotational stability for the entire rotating mechanism, while the vertically arranged side plates 224 provide a supporting surface for the mounting of the feeding rod 221. The angled arrangement of the side plates 224 structurally defines the layout of multiple workstations (i.e., multiple feeding rods 221), which is the core physical basis for realizing the aforementioned large-capacity, continuous feeding function. Furthermore, the dedicated feeding rod base 225 on the side plate 224 provides a standardized installation interface. This not only ensures that each feed rod 221 is securely installed at a precise and consistent angle, guaranteeing the reliability of gravity sliding and rotation positioning, but also greatly simplifies the assembly and subsequent maintenance process, making the replacement or repair of a single feed rod 221 convenient and quick, thereby improving the manufacturability and maintainability of the entire device.

[0054] See Figure 2 In one embodiment, the feeding rod base 225 has a first mounting surface and a second mounting surface arranged at an angle. The bracket 220 also includes a feeding connecting rod 226. The first mounting surface is used to install the feeding rod 221, and the second mounting surface is used to install the feeding connecting rod 226. The ends of the feeding rod 221 and the feeding connecting rod 226 away from the feeding rod base 225 are connected by a baffle plate 222.

[0055] This embodiment aims to solve the problems of bending, sagging, or vibration that may occur when a single cantilevered feeding rod 221 carries a large number of racket frames. Its core lies in enhancing the structural rigidity of each feeding station. By designing the feeding rod base 225 with first and second mounting surfaces at an angle and introducing a feeding connecting rod 226, a stable triangular mechanical structure is constructed.

[0056] Specifically, the feeding rod 221 and the feeding connecting rod 226 are fixed to two mounting surfaces of the base, and connected at their ends away from the base by a baffle plate 222, forming a closed triangular frame. This design improves the strength and bending and torsional resistance of the entire feeding assembly. Compared to a single-rod cantilever structure, this triangular frame structure is more stable and can effectively prevent sagging deformation caused by the weight of the gripper frame. This ensures that the baffle plate 222 at the end of the feeding rod 221 and the gripper frame to be grasped can always maintain a precise and fixed height and position. This is crucial for the accurate positioning of the subsequent guiding mechanism 300 and the stable gripping of the material handling mechanism 400, ultimately improving the long-term operating accuracy and reliability of the equipment.

[0057] See Figure 2 and Figure 3 In one embodiment, a rotary drive motor 230 is provided on the column 210, and the bracket 220 is connected to the column 210 through the rotary drive motor 230. A feeding sensor 227 is provided on the side of the feeding rod base 225 facing the column 210. A feeding sensor 231 for detecting changes in the feeding sensor 227 is provided on the rotary drive motor 230, and a sensor 228 is provided on the feeding limit block 320.

[0058] This embodiment introduces a complete automated control system into the feeding unit, upgrading it from a mechanical device into an intelligent equipment capable of autonomous judgment and execution. By adding a rotary drive motor 230 to the column 210 and connecting it to the hanger 220, the switching of the hanger 220's workstations is automated, replacing manual rotation, reducing labor intensity, and providing a foundation for unmanned operation. To ensure rotation accuracy, a closed-loop positioning system consisting of a feeding sensor 227 and a feeding sensor 231 is set up in the solution, providing precise position feedback for the rotary drive motor 230. When the sensor detects the sensor at a specific workstation, it confirms that the hanger 220 has rotated to the preset precise working position aligned with the picking mechanism 400, thereby ensuring the accuracy of subsequent gripping actions.

[0059] The sensor 228 has a dual technical effect: it can detect in real time whether a grabber frame is in place, serving as a "start" signal to trigger the material handling mechanism 400 to begin operation; it can also determine whether the current feeding rod 221 is empty (i.e., after a grabber frame is removed, no new grabber frame slides in within a specified time), and use this as a "material change" signal to trigger the rotary drive motor 230 to switch to the next material-filled station. In summary, these components work together to form a complete control chain integrating drive, positioning, detection, and logical judgment, enabling the feeding unit to automatically complete the cycle of "material availability judgment—grabbing—empty material judgment—material change," achieving truly fully automatic and uninterrupted operation.

[0060] See Figure 4 and Figure 5 In one embodiment, the guide mechanism 300 further includes a flipping pressure plate 330 and a drive assembly 340. The drive assembly 340 includes a flipping cylinder 341, a mounting base 342, and a flipping block 343. The flipping cylinder 341 is connected to the frame 100 through the mounting base 342. A connecting rod is rotatably connected between the flipping cylinder 341 and the flipping block 343, and the flipping block 343 is driven to rotate through the connecting rod structure. The flipping pressure plate 330 is connected to the flipping block 343. Under the drive of the flipping cylinder 341, the flipping pressure plate 330 rotates to form a guide groove 350 with the feeding baffle 310. The guide groove 350 is used to accommodate the rod of the frame.

[0061] This embodiment aims to achieve more precise and stable positioning of the racket frame, particularly in the attitude control of the racket frame shaft (i.e., the racket shaft). By adding a drive assembly 340, consisting of a flipping cylinder 341, a flipping pressure plate 330 is driven. When the racket frame slides into the gripping position, the flipping pressure plate 330 flips under the cylinder's drive, forming a "guide groove 350" together with the fixed feeding baffle 310. This guide groove 350 can accommodate the racket frame shaft, and through clamping on both sides, it provides precise center positioning and attitude locking, effectively preventing possible displacement of the racket shaft. Compared to relying solely on a flat baffle for unidirectional limiting, this actively formed guide groove 350 provides a higher level of constraint, greatly improving the racket frame's attitude stability and positional repeatability before gripping, creating more ideal conditions for the subsequent precise and reliable gripping by the material handling mechanism 400.

[0062] See Figure 6 and Figure 7 In one embodiment, the material handling mechanism 400 includes a stand 410, a slide rail 420, a linear drive motor 430, and a clamping assembly 440. The stand 410 is mounted on the frame 100, and the slide rail 420 and the linear drive motor 430 are mounted on the stand 410. The slide rail 420 is also provided with a sliding base 450 for mounting the clamping assembly 440. The linear drive motor 430 drives the clamping assembly 440 to move along the slide rail 420 to switch between the material handling station and the material feeding station.

[0063] This embodiment uses a support frame 410 as a base, on which a slide rail 420 and a linear drive motor 430 are mounted. This design constructs a standard linear execution module. The gripping component 440 is mounted on a sliding base 450 that can move along the slide rail 420 and is precisely driven by the linear drive motor 430. The slide rail 420 provides high rigidity and precise guidance, ensuring the stability and trajectory accuracy of the gripping component 440 during high-speed movement. The linear drive motor 430 provides a programmable and controllable power source, capable of precisely controlling the moving speed, acceleration, and stopping position of the gripping component 440. Therefore, this structure can reliably achieve rapid and precise switching of the gripping component 440 between the "picking station" and the "feeding station," completing the material handling function from point A to point B. It forms the basis for automated "pick-and-place" operations and provides a guarantee for subsequent more complex multi-axis movements and precise positioning.

[0064] See Figure 6 and Figure 7In one embodiment, the gripping assembly 440 includes a first linear cylinder 441 arranged in a vertical direction, a second linear cylinder 442 arranged in a horizontal direction, and a gripper 443. The first linear cylinder 441 is connected to the sliding base 450 through a mounting plate. The second linear cylinder 442 is disposed at the moving end of the first linear cylinder 441. The gripper 443 is connected to the second linear cylinder 442. The second linear cylinder 442 is used to drive the gripper 443 to move closer to or away from the rotating feeding mechanism 200.

[0065] This embodiment introduces a first linear cylinder 441 positioned vertically, which drives the gripper 443 to descend to approach the frame and ascend to detach from the workstation. This vertical displacement is essential for the "grabbing" and "placing" operations. Furthermore, a second linear cylinder 442 positioned horizontally is installed at the moving end of the first cylinder, adding forward and backward extension (Y-axis) capability to the gripper 443. This allows the gripper 443 to precisely extend into the narrow space formed by the guide mechanism 300 for gripping and smoothly retract after successful gripping, avoiding collisions with the equipment. Combined with the main body translation (X-axis) function provided in the previous embodiment, the introduction of these two cylinders gives the gripping assembly 440 three degrees of freedom, enabling it to execute a complete and complex spatial motion sequence: translation above the workstation—descend—extend—clamp—retract—ascend—translate to the feeding position, thus ensuring the flexibility, accuracy, and reliability of the entire picking and placing process.

[0066] See Figure 6 and Figure 7 In one embodiment, a third linear cylinder 444 is provided between the gripper 443 and the second linear cylinder 442. The third linear cylinder 444 is connected to the moving end of the second linear cylinder 442. A rack 445 is provided on the output shaft of the third linear cylinder 444, and a gear 446 is provided on the gripper 443. The gear 446 meshes with the rack 445. Driven by the third linear cylinder 444, the gripper 443 rotates along the axis of the gear 446 to switch between a horizontal material picking station and a vertical material unloading station.

[0067] This embodiment adds a third linear cylinder 444 between the gripper 443 and the second linear cylinder 442, and utilizes the meshing of the rack 445 on its output shaft with the gear 446 on the gripper 443 to convert the linear reciprocating motion generated by the third linear cylinder 444 into the rotational motion of the gripper 443 around its axis. The frame is placed vertically during loading for convenient storage and transport, but needs to be placed horizontally in subsequent processes such as handle connection. This rotational function bridges these two different posture requirements, greatly enhancing the process adaptability and flexibility of the entire loading unit, ensuring seamless integration with downstream equipment with different needs, and is a key link in achieving fully automated production.

[0068] See Figure 2 In one embodiment, the hanger 220 further includes a reinforcing connecting plate 229, one end of which is connected to the side plate 224 and the other end to the base plate 223. The purpose of this embodiment is to further strengthen the overall mechanical structure of the rotating hanger 220 to improve its stability and durability under dynamic operation. By adding a reinforcing connecting plate 229, with one end connected to the side plate 224 and the other end connected to the base plate 223, a triangular support structure is constructed between the vertical side plate 224 and the horizontal base plate 223. Utilizing the stability principle of a triangle, this greatly enhances the rigidity and deformation resistance at the connection between the side plate 224 and the base plate 223. When the hanger 220 carries heavy objects and rotates for acceleration and deceleration, this connection point is the main stress concentration area. The introduction of the reinforcing connecting plate 229 can effectively disperse and bear these stresses, prevent bending or fatigue at the connection, and thus ensure that the entire rotating hanger 220 maintains its geometric accuracy during long-term operation. This avoids positioning errors caused by structural shaking or deformation, and ultimately improves the overall robustness, smooth operation and service life of the equipment.

[0069] An embodiment of this utility model also provides a carbon fiber badminton racket handle production line, which further includes a handle attaching unit and a feeding unit. The feeding unit, the handle attaching unit and the feeding unit are connected to each other in the order of the processes. The feeding unit adopts the feeding unit described above.

[0070] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
