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 traditional automated handle-joining devices, represented by the aforementioned patents, suffer from low integration of automation processes and a lack of refined process control and closed-loop quality management when moving towards higher efficiency and higher quality intelligent manufacturing. This prevents them from achieving truly efficient and high-quality fully automated production. Firstly, in terms of core processes, the adhesive application roller brush method is relatively coarse, making it difficult to precisely control the amount and application position of adhesive, easily leading to unstable bonding strength. Secondly, in terms of the production process, the automated chain is interrupted after handle joining, lacking integrated online quality inspection and automatic finished product sorting functions. This necessitates reliance on subsequent manual transfer, inspection, and sorting, which not only disrupts the production rhythm and reduces overall efficiency but also fails to avoid subjective errors and quality risks introduced by manual operation. Utility Model Content

[0018] The glue dispensing mechanism includes a rubber sleeve glue dispensing assembly and a wooden handle glue dispensing assembly. The rubber sleeve glue dispensing assembly is located at the front end of the wooden handle glue dispensing assembly and can apply glue to the wooden handle, so that the rubber sleeve is fixed to the wooden handle. The wooden handle glue dispensing assembly can inject glue into the insertion gap between the wooden handle and the frame, so that the frame and the wooden handle are fixedly set.

[0019] Optionally, the fixing assembly includes a base plate disposed on the receiving frame, and a support member, a pressing member, and a clamping member disposed on the base plate;

[0020] The support member is used to support the top of the racket frame. The support member is provided with a T-head stop block, which is used to support and limit the end face of one side of the T-head of the racket frame. The clamping member includes a clamping cylinder and an abutment block.

When a pair of clamping plates clamp the racket handle, the racket handle is located in the groove and rotates and abuts against the follower pulley.

[0026] The support and clamping parts on the fixing component are slidably connected to its base plate. When the racket frame rotation component drives the racket frame to rotate, the support and clamping parts on the fixing component slide out of the racket frame under the action of external force.

The first slide rail is horizontally disposed and perpendicular to the axis of the badminton racket. A first detection member is disposed on the first slide rail. The first driving member drives the first detection member to move horizontally along the first slide rail to detect the symmetry of the racket frame relative to the racket shaft.

[0032] The first detection element is disposed facing the lower surface of the racket frame. The first detection element is a pair of fiber optic sensors. The pair of fiber optic sensors are connected to the slide rail via a slider. Under the drive of the first driving element, the pair of fiber optic sensors move horizontally synchronously relative to each other or towards each other along the first slide rail.

One end of the mounting plate is disposed on the slide rail, and the other end is provided with an adjustment plate. The adjustment plate has an adjustment groove for setting the fiber optic sensors. Under the drive of the second driving component, the pair of mounting plates move vertically and synchronously relative to each other or towards each other along the first slide rail.

[0035] A fiber optic sensor is centrally located on one of the adjustment plates, and a pair of fiber optic sensors are provided on the other adjustment plate. The fiber optic sensor of the second detection element is positioned facing the inner wall of the racket frame.

The ground rail is parallel to the straight line where the material placement rack, the waste rack, and the receiving mechanism are located. The material handling robotic arm moves along the ground rail to pick up the racket on the receiving mechanism and send it to the waste rack or the material placement rack.

[0038] The waste rack is connected to the unloading frame via a lifting assembly. The waste rack includes a pull-out base plate and baffles on both sides of the pull-out base plate. The baffles and the pull-out base plate together form a space to accommodate waste rackets. The waste rack moves up and down under the drive of the lifting assembly to move closer to or further away from the picking and unloading robotic arm.

[0039] The pull-out base plate of the waste rack is slidably connected to the lifting assembly. Under the action of external force, the waste rack moves away from the lifting assembly in the horizontal direction to remove the waste rackets inside the waste rack.

[0040] Compared with the prior art, the technical solution provided in this application has the following advantages:

[0041] The aforementioned carbon fiber badminton racket assembly line utilizes a rotary feeding mechanism with an inclined feeding rod, allowing the racket frame to automatically and sequentially slide downwards under gravity without additional power. This achieves simple and reliable continuous feeding, while the stacked arrangement also buffers the material. Its rotary multi-station design significantly increases the amount of material prepared at one time and allows for "production-while-replenishing" without stopping the machine, minimizing downtime. To support the complex handle-attaching process, a synchronous transfer robotic arm constructs a linear multi-station platform, providing a smooth foundation for high-precision automated processes. After handle attachment, the unloading unit automatically picks up the racket from the previous process, and its integrated inspection mechanism automatically checks the racket's flatness and symmetry—two key quality indicators—overcoming the subjective drawbacks and low efficiency of manual inspection. Ultimately, the material unloading and storage mechanism can automatically send rackets to the qualified product rackets or the unqualified product scrap bins through the material handling components based on the test results, forming a closed-loop automated system of "detection-feedback-execution". This achieves intelligent product sorting and significantly improves the automation level and management efficiency of the production line. Attached Figure Description

[0069] 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.

[0070] See Figure 1 This utility model provides a carbon fiber badminton racket assembly line, wherein the carbon fiber badminton racket includes a frame, a rubber sleeve, and a wooden handle, and includes a feeding unit 100, a handle-joining unit 200, and a discharging unit 300. The feeding unit, handle-joining unit, and discharging unit are connected to each other in a process sequence, wherein:

[0071] The feeding unit includes a rotary feeding mechanism 110, which includes a column 111 mounted on the feeding frame and a hanging frame rotatably connected to the column. The hanging frame includes a plurality of feeding rods 112 for suspending the frame. The plurality of feeding rods are arranged at an angle to each other. One end of each feeding rod is provided with a baffle plate 113. The height of the end of the feeding rod near the column is higher than the height of the end connected to the baffle plate, so that the frame can be stacked along the feeding rod.

[0072] The receiving unit 200 includes a synchronous transplanting robotic arm 210, which includes a linear synchronous belt 211 and a plurality of synchronous grippers 212 arranged corresponding to the receiving process. The plurality of synchronous grippers are arranged on the linear synchronous belt and, driven by the linear synchronous belt, send the frame in the fixing component of the corresponding process of each synchronous gripper to the corresponding next process.

[0073] The feeding unit 300 includes a detection mechanism 310 and a feeding storage mechanism 320. The detection mechanism is used to detect the flatness and symmetry of the carbon fiber badminton racket after the handle-joining process is completed. The feeding storage mechanism includes a material picking and placing component 321, a material placing rack 322 and a waste rack 323, which are used to send the carbon fiber badminton racket to the material placing rack or waste cabinet according to the detection results.

[0074] The aforementioned carbon fiber badminton racket assembly line utilizes a rotary feeding mechanism with an inclined feeding rod, allowing the racket frame to automatically and sequentially slide downwards under gravity without additional power. This achieves simple and reliable continuous feeding, while the stacked arrangement also buffers the material. Its rotary multi-station design significantly increases the amount of material prepared at one time and allows for "production-while-replenishing" without stopping the machine, minimizing downtime. To support the complex handle-attaching process, a synchronous transfer robotic arm constructs a linear multi-station platform, providing a smooth foundation for high-precision automated processes. After handle attachment, the unloading unit automatically picks up the racket from the previous process, and its integrated inspection mechanism automatically checks the racket's flatness and symmetry—two key quality indicators—overcoming the subjective drawbacks and low efficiency of manual inspection. Ultimately, the material unloading and storage mechanism can automatically send rackets to the qualified product rackets or the unqualified product scrap bins through the material handling components based on the test results, forming a closed-loop automated system of "detection-feedback-execution". This achieves intelligent product sorting and significantly improves the automation level and management efficiency of the production line.

[0075] See Figure 2 This utility model provides a racket frame feeding unit 100 for a carbon fiber badminton racket assembly line. The feeding unit 100 is located at the first station of the assembly line and includes:

[0076] 120mm feeding frame;

[0077] The feeding mechanism includes a column 111 mounted on the feeding frame 120 and a bracket rotatably connected to the column 111. The bracket includes a feeding rod 112 for suspending the racket frame. One end of the feeding rod 112 is provided with a baffle plate 113. The height of the end of the feeding rod 112 near the column 111 is higher than the height of the end connected to the baffle plate 113, so that the racket frame can be stacked along the feeding rod 112.

[0078] The guiding mechanism 130 includes a feeding baffle 131 and a feeding limiting block 132. The feeding baffle 131 is located at the discharge port and fixed on the feeding frame 120, and can laterally limit the several frames on the feeding rod 112. The feeding limiting block 132 is located at the end of the feeding baffle 131 away from the column 111, and can longitudinally limit the frames that move to the feeding limiting block 132.

[0079] And a material-grabbing mechanism 140 set on the feeding frame 120, used to grab the frame that has moved to the feeding limit block 132 and transport it to the receiving unit 200.

[0080] The racket frame feeding unit 100 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 rotatably connected to the column 111, and the feeding rod 112 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.

[0081] Based on this, the lateral limit provided by the loading baffle 131 and the longitudinal limit provided by the loading limit block 132 are combined to form a positioning point, ensuring that each frame that slides to this point can be constrained in a fixed three-dimensional space position, ensuring the repeatability and consistency of the position, and providing a stable prerequisite for subsequent robotic arm grasping.

[0082] Finally, the material handling mechanism 140 is directly responsible for performing the grabbing and conveying actions. It will be grabbed by the frame positioned by the guide mechanism 130 and sent to the next receiving unit 200, 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.

[0083] An embodiment of this utility model also provides a racket frame feeding unit 100 for a carbon fiber badminton racket assembly line. The feeding unit 100 is located at the first station of the assembly line and includes:

[0084] 120mm feeding frame;

[0085] The rotary feeding mechanism 110 includes a column 111 mounted on a feeding frame 120 and a hanger rotatably connected to the column 111. The hanger includes a plurality of feeding rods 112 for suspending the frame. The feeding rods 112 are arranged at an angle to each other. One end of the feeding rod 112 is provided with a baffle plate 113. The height of the end of the feeding rod 112 near the column 111 is higher than the height of the end connected to the baffle plate 113, so that the frame can be stacked along the feeding rod 112.

[0086] The guiding mechanism 130 includes a feeding baffle 131 and a feeding limiting block 132. The feeding baffle 131 is located at the discharge port and fixed on the feeding frame 120, and can laterally limit the several frames on the feeding rod 112. The feeding limiting block 132 is located at the end of the feeding baffle 131 away from the column 111, and can longitudinally limit the frames that move to the feeding limiting block 132.

[0087] And a material-grabbing mechanism 140 set on the feeding frame 120, used to grab the frame that has moved to the feeding limit block 132 and transport it to the receiving unit 200.

[0088] This embodiment introduces a rotary feeding mechanism 110 based on the aforementioned automated feeding scheme. The mechanism integrates several feeding rods 112 arranged at an angle on its frame, upgrading a single feeding channel into a rotary, multi-station material bin, significantly increasing the equipment's single-batch material preparation capacity and material buffering capacity. When the rack of one feeding rod 112 is completely empty, the mechanism can rotate to quickly switch another fully loaded feeding rod 112 to the working position, supplying the guiding mechanism 130 and the material handling mechanism 140 to continue operation. Simultaneously, operators can replenish empty feeding rods 112 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.

[0089] See Figure 3In one embodiment, the rack further includes a rack base plate 114 and rack side plates 115. The rack side plates 115 are disposed on the rack base plate 114, and several rack side plates 115 are arranged at an angle to each other. A feeding rod base 116 is provided on the rack side plate 115 for mounting the feeding rod 112. In this embodiment, the rack in the rotating feeding mechanism 110, by adding the rack base plate 114 and rack side plates 115, together constitutes a bearing platform. The rack base plate 114 provides basic rigidity and rotational stability for the entire rotating mechanism, while the vertically arranged rack side plates 115 provide a support surface for the installation of the feeding rod 112. The design of arranging several rack side plates 115 at an angle to each other structurally clarifies the layout of multiple workstations (i.e., multiple feeding rods 112), which is the core physical basis for realizing the aforementioned large-capacity, continuous feeding function. Furthermore, a dedicated base for the feeding rod 112 is provided on the side plate 115 of the hanger, offering a standardized installation interface. This not only ensures that each feeding rod 112 is securely installed at a precise and consistent angle, guaranteeing the reliability of gravity-driven descent and rotational positioning, but also greatly simplifies the assembly and subsequent maintenance process, making the replacement or repair of individual feeding rods 112 convenient and quick, thereby improving the manufacturability and maintainability of the entire device.

[0090] See Figure 3 In one embodiment, the base of the feeding rod 112 has a first mounting surface and a second mounting surface arranged at an angle. The bracket also includes a feeding connecting rod 117. The first mounting surface is used to install the feeding rod 112, and the second mounting surface is used to install the feeding connecting rod 117. The ends of the feeding rod 112 and the feeding connecting rod 117 away from the base of the feeding rod 112 are connected by a baffle plate 113.

[0091] This embodiment aims to solve the problems of bending, sagging, or vibration that may occur when a single cantilevered feeding rod 112 carries a large number of racket frames. Its core lies in enhancing the structural rigidity of each feeding station. By designing the base of the feeding rod 112 to have first and second mounting surfaces at an angle and introducing a feeding connecting rod 117, a stable triangular mechanical structure is constructed.

[0092] Specifically, the feeding rod 112 and the feeding connecting rod 117 are fixed to two mounting surfaces of the base, and connected at their ends away from the base by a baffle plate 113, 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 113 at the end of the feeding rod 112 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 130 and the stable grasping of the material handling mechanism 140, ultimately improving the long-term operating accuracy and reliability of the equipment.

[0093] See Figures 3 to 5 In one embodiment, a rotary drive motor 150 is provided on the column 111, and the bracket is connected to the column 111 through the rotary drive motor 150. A feeding sensor 151 is provided on the side of the base of the feeding rod 112 facing the column 111. A feeding sensor 152 for detecting changes in the feeding sensor 151 is provided on the rotary drive motor 150, and a sensor 1321 is provided on the feeding limit block 132.

[0094] This embodiment introduces a complete automated control system into the feeding unit 100, upgrading it from a mechanical device into an intelligent equipment capable of autonomous judgment and execution. By adding a rotary drive motor 150 to the column 111 and connecting it to the hanger, the switching of the hanger's workstation 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 151 and a feeding sensor 152 is set up in the solution, providing precise position feedback for the rotary drive motor 150. When the sensor detects the sensor at a specific workstation, it confirms that the hanger has rotated to the preset precise working position aligned with the picking mechanism 140, thereby ensuring the accuracy of subsequent gripping actions.

[0095] The sensor 1321 can detect in real time whether a grabber frame is in place, serving as a "start" signal to trigger the material handling mechanism 140 to begin operation; it can also determine whether the current feeding rod 112 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 150 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 logic judgment, enabling the feeding unit 100 to automatically complete the cycle of "material availability judgment—grabbing—empty material judgment—material change," achieving truly fully automatic and uninterrupted operation.

[0096] See Figure 5In one embodiment, the guide mechanism 130 further includes a flipping pressure plate 133 and a drive assembly. The drive assembly includes a flipping cylinder 134, a mounting base 135, and a flipping block 136. The flipping cylinder 134 is connected to the feeding frame 120 through the mounting base 135. A connecting rod is rotatably connected between the flipping cylinder 134 and the flipping block 136, and the flipping block 136 is driven to rotate through the connecting rod structure. The flipping pressure plate 133 is connected to the flipping block 136. Under the drive of the flipping cylinder 134, the flipping pressure plate 133 rotates to form a guide groove 137 with the feeding baffle 131. The guide groove 137 is used to accommodate the rod of the racket frame.

[0097] This embodiment aims to deepen and enhance the function of the guiding mechanism 130 to achieve more precise and stable positioning of the racket frame, especially in the attitude control of the racket frame rod (i.e., the racket shaft). By adding a driving assembly consisting of a flipping cylinder 134 and other components to drive a flipping pressure plate 133, this solution upgrades the original passive limiting function to active constraint positioning. Its core technical effect is that when the racket frame slides into the gripping position, the flipping pressure plate 133 flips under the cylinder drive, forming a guide groove 137 together with the fixed feeding baffle 131. This guide groove 137 can accommodate the racket frame rod, and through clamping on both sides, it achieves 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 137 provides a higher level of constraint, greatly improving the attitude stability and positional repeatability of the racket frame before gripping, creating more ideal conditions for the subsequent precise and reliable gripping by the material handling mechanism 140.

[0098] See Figure 6 In one embodiment, the material handling mechanism 140 includes a stand, a slide rail, a linear drive motor, and a clamping assembly. The stand is mounted on the loading frame 120, and the slide rail and the linear drive motor are mounted on the stand. The slide rail is also provided with a sliding base for mounting the clamping assembly. The linear drive motor drives the clamping assembly to move along the slide rail to switch between the material handling station and the material feeding station.

[0099] This embodiment uses a support frame with a slide rail and linear drive motor mounted on it. This design constructs a standard linear execution module. The gripping component is mounted on a sliding base that can move along the slide rail and is precisely driven by the linear drive motor. The slide rail provides high rigidity and precise guidance, ensuring the smoothness and accuracy of the gripping component's trajectory during high-speed movement. The linear drive motor provides a programmable and controllable power source, enabling precise control of the gripping component's moving speed, acceleration, and stopping position. Therefore, this structure can reliably achieve rapid and precise switching between the gripping component 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.

[0100] See Figure 6 In one embodiment, the gripping assembly includes a first linear cylinder 141 arranged in a vertical direction, a second linear cylinder 142 arranged in a horizontal direction, and a gripper. The first linear cylinder 141 is connected to a sliding base via a mounting plate. The second linear cylinder 142 is disposed at the moving end of the first linear cylinder 141. The gripper is connected to the second linear cylinder 142. The second linear cylinder 142 is used to drive the gripper to move closer to or away from the rotating feeding mechanism 110.

[0101] This embodiment introduces a first linear cylinder 141 arranged vertically, which drives the gripper 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 142, arranged horizontally, is installed at the moving end of the first cylinder, adding forward and backward extension (Y-axis) capability to the gripper. This allows the gripper to precisely extend into the narrow space formed by the guide mechanism 130 for grasping and smoothly retract after successful grasping, 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 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.

[0102] See Figure 6In one embodiment, a third linear cylinder 143 is provided between the gripper and the second linear cylinder 142. The third linear cylinder 143 is connected to the moving end of the second linear cylinder 142. A rack 144 is provided on the output shaft of the third linear cylinder 143, and a gear 145 is provided on the gripper. The gear 145 meshes with the rack 144. Driven by the third linear cylinder 143, the gripper rotates along the axis of the gear 145 to switch between a horizontal material picking station and a vertical material unloading station.

[0103] This embodiment adds a third linear cylinder 143 between the gripper and the second linear cylinder 142, and utilizes the meshing of the rack 144 on its output shaft with the gear 145 on the gripper to convert the linear reciprocating motion generated by the third linear cylinder 143 into the rotational motion of the gripper 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 100, ensuring seamless integration with downstream equipment with different needs, and is a key link in achieving fully automated production.

[0104] See Figure 3 In one embodiment, the hanger further includes a reinforcing connecting plate 118, one end of which is connected to the hanger side plate 115, and the other end is connected to the hanger base plate 114. The purpose of this embodiment is to further strengthen the overall mechanical structure of the rotating hanger to improve its stability and durability under dynamic operation. By adding a reinforcing connecting plate 118, with one end connected to the hanger side plate 115 and the other end connected to the hanger base plate 114, this solution constructs a triangular support structure between the vertical hanger side plate 115 and the horizontal hanger base plate 114. Utilizing the stability principle of a triangle, this greatly enhances the rigidity and deformation resistance at the connection between the hanger side plate 115 and the hanger base plate 114. When the hanger bears heavy loads and rotates for acceleration and deceleration, this connection point is the main stress concentration area. The introduction of the reinforcing connection plate 118 can effectively disperse and bear these stresses, prevent bending or fatigue at the connection, and thus ensure that the entire rotating hanger maintains its geometric accuracy during long-term operation. It avoids positioning errors caused by structural shaking or deformation, and ultimately improves the overall robustness, smooth operation and service life of the equipment.

[0105] See Figure 7 An embodiment of this utility model also provides a handle assembly unit 200 for a carbon fiber badminton racket assembly line. The carbon fiber badminton racket includes a frame, a rubber sleeve, and a wooden handle. The handle assembly unit 200 is located at the second station of the assembly line and includes:

[0106] The handle receiving frame 220 is provided with several fixing components, which are used to fix the racket frame in several processes of corresponding handle processing.

[0107] The insertion mechanism 230 includes a rubber sleeve conveying assembly 231, a wooden handle conveying assembly 232, and an insertion robot 233 capable of inserting the rubber sleeve and wooden handle conveyed by the rubber sleeve conveying assembly 231 and the wooden handle conveying assembly 232 into the racket frame.

[0108] The glue dispensing mechanism 240 includes a rubber sleeve glue dispensing assembly 241 and a wooden handle glue dispensing assembly 242. The rubber sleeve glue dispensing assembly 241 is located at the front end of the wooden handle glue dispensing assembly 242 and can apply glue to the wooden handle so that the rubber sleeve is fixed to the wooden handle. The wooden handle glue dispensing assembly 242 can inject glue into the insertion gap between the wooden handle and the frame so that the frame and the wooden handle are fixedly set.

[0109] The synchronous transplanting robotic arm 210 includes a linear synchronous belt 211 and a plurality of synchronous grippers 212 corresponding to the fixed components. The plurality of synchronous grippers 212 are arranged on the linear synchronous belt 211 and, driven by the linear synchronous belt 211, send the frame in the fixed component of the corresponding process of each synchronous gripper 212 to the corresponding next process.

[0110] This embodiment integrates the installation and bonding of the rubber sleeve into an automated process by setting up an insertion mechanism 230 including a rubber sleeve delivery assembly 231 and subdividing the dispensing mechanism 240 into a rubber sleeve dispensing assembly 241 that can pre-fix the rubber sleeve and a wooden handle dispensing assembly 242 responsible for final fixing. This achieves a more complete fully automated assembly process than existing technologies. Addressing the problems of existing technologies that use external roller brushes for gluing, resulting in a coarse application and insufficient bonding strength, the wooden handle dispensing assembly 242 of this application fundamentally improves the gluing process by directly injecting glue into the insertion gap between the wooden handle and the frame. This internal injection ensures that the glue penetrates deeply and precisely into the core bonding area, thereby achieving superior bonding strength and reliability compared to existing surface gluing methods. Finally, by setting up several fixing components and a synchronous transfer robotic arm 210, a linear multi-station platform is constructed, providing the necessary foundation for realizing the complex processes of step-by-step, precise insertion and dispensing, ensuring the smooth operation of the entire high-quality, high-precision automated process.

[0111] See Figure 8 and Figure 9 In one embodiment, the fixing assembly includes a base plate 221 disposed on the handle frame 220, and a support member 222, a pressing member 223 and a clamping member 224 disposed on the base plate 221;

[0112] The support member 222 is used to support the top of the racket frame. The support member 222 is provided with a T-head stop 225, which is used to support and limit the end face of one side of the T-head of the racket frame. The clamping member 223 includes a clamping cylinder 2231 and an abutment block 2232. The abutment block 2232 abuts against the other end face of the T-head of the racket frame under the drive of the clamping cylinder 2231, and cooperates with the T-head stop 225 to fix the T-head of the racket frame. The clamping member 224 includes a pair of clamping plates 2241, which are used to clamp the racket shaft.

[0113] In this embodiment, by combining the support member 222, the clamping member 223, and the clamping member 224, multi-point coordinated fixation of the badminton racket is achieved. Specifically, the T-head stop 225 on the support member 222 cooperates with the abutment block 2232 driven by the clamping cylinder 2231 to firmly clamp the racket's T-head area from both sides, effectively preventing its horizontal displacement; at the same time, the clamping member 224, composed of a pair of clamping plates 2241, locks the shaft portion. This simultaneous fixation of the T-head and shaft ensures that the racket will not shake or rotate during high-precision operations such as splicing and internal glue injection, providing a key guarantee for the accuracy of subsequent processes. In addition, the clamping member 223 is driven by the clamping cylinder 2231, enabling automated execution of clamping and releasing actions, which matches the automated process of the entire unit, improving production cycle and efficiency.

[0114] See Figure 10 In one embodiment, the fixing component corresponding to the plug-in rubber sleeve station is also used to connect the tray conveyed by the feeding unit 100. The base plate 221 of the fixing component is provided with a rotary motor 228. Driven by the rotary motor 228, the fixing component rotates in the plane of its base plate 221.

[0115] In the carbon fiber badminton racket assembly line, there is a discrepancy between the output posture of the previous unit (feeding unit 100) and the processing posture of this unit (handle receiving unit 200). By equipping this fixing component with a rotary motor 228 that allows it to rotate horizontally, it can actively match the racket frame delivered by the feeding unit 100. Regardless of the angle at which the feeding unit 100 delivers the racket, the fixing component can first rotate to the optimal receiving angle for connection, and then rotate back to the standard processing angle to align with the path of subsequent processes. This design simplifies the precision requirements of the upstream feeding unit 100, reduces the difficulty of production line integration, and makes the factory layout design more flexible, ultimately ensuring efficient, smooth, and reliable material flow between different units.

[0116] See Figure 10In one embodiment, the fixing component corresponding to the insertion of the rubber sleeve also includes a rubber sleeve guide 226, which includes a guide drive cylinder 2261 and a pair of guide abutments 2262. The guide abutments 2262 are provided with grooves suitable for accommodating the racket shaft and protrusions 22621 for abutting the rubber sleeve. The pair of guide abutments 2262 are fitted around the racket shaft and, driven by the guide drive cylinder 2261, push the rubber sleeve to move along the racket shaft.

[0117] In automated assembly, pushing small and lightweight components like rubber sleeves along a slender handle to their precise positions is a challenge, as tilting and jamming are common. This embodiment addresses this by using a pair of guide abutments 2262 with grooves to accommodate the handle. During operation, these guides first align with the handle, creating a coaxial guide for the subsequent pushing motion. Then, driven by a guide cylinder 2261, the protrusions 22621 on the abutments push the rubber sleeve along the handle. Since the entire guide is aligned with the handle, the thrust applied to the rubber sleeve is entirely axial, effectively preventing tilting and jamming during sliding. This ensures smooth and precise installation into the intended position, significantly improving the automation success rate and positioning accuracy of this process.

[0118] See Figure 10 In one embodiment, the fixing components corresponding to the insertion of the rubber sleeve and the insertion of the wooden handle further include a rubber sleeve fixing claw 227. The rubber sleeve fixing claw 227 is disposed on the base plate 221 and has a fixing cavity adapted to the rubber sleeve. The rubber sleeve moves to abut against the inner wall surface of the fixing cavity under the push of the rubber sleeve guide 226.

[0119] During the insertion and connection of the rubber sleeve, when the rubber sleeve guide 226 pushes the rubber sleeve along the racket shaft, the rubber sleeve fixing claw 227, which has an adaptive fixing cavity, provides an abutment surface. This means that the final position of the rubber sleeve no longer depends solely on the stroke of the push cylinder, but is determined by its contact with the inner wall of the fixing cavity, which greatly improves the accuracy and consistency of the rubber sleeve installation depth.

[0120] Secondly, in the subsequent insertion of the wooden handle, the rubber sleeve retaining claw 227 continues to function. It firmly secures the pre-positioned rubber sleeve, and when the wooden handle is inserted and pressed against the rubber sleeve, the rubber sleeve retaining claw 227 provides a reverse support force, preventing the rubber sleeve from shifting under pressure. This ensures that the wooden handle, rubber sleeve, and shaft can be tightly and reliably assembled together, guaranteeing the final assembly quality.

[0121] See Figure 11In one embodiment, the adhesive sleeve dispensing assembly 241 includes an adhesive sleeve dispensing head 2411 and a wooden handle rotating gripper 2412. The adhesive sleeve dispensing head 2411 is mounted on a gantry frame and is driven to the adhesive sleeve dispensing position by the adhesive sleeve dispensing drive 2413 to dispense adhesive onto the contact surface between the wooden handle and the adhesive sleeve. The wooden handle rotating gripper 2412 is mounted on the handle receiving frame 220 and is used to clamp and drive the wooden handle to rotate after it comes into contact with the adhesive sleeve, so as to evenly apply the adhesive.

[0122] In traditional dispensing and pressing processes, uneven adhesive distribution can easily occur, potentially leading to weak bonding in some areas. This embodiment optimizes this process: First, the dispensing head 2411 on the gantry allows for precise application of a measured amount of adhesive to the designated contact surface of the wooden handle. Second, after the wooden handle comes into contact with the adhesive sleeve, the rotating gripper 2412 drives the handle to rotate. This rotation no longer passively relies on pressure to spread the adhesive, but actively and forcefully spreads the adhesive evenly across the entire annular contact surface, ensuring a 360-degree, seamless bond and significantly enhancing the strength of the connection between the adhesive sleeve and the wooden handle, as well as the product's durability.

[0123] See Figure 12 In one embodiment, the wooden handle dispensing assembly 242 includes a wooden handle dispensing head 2421 and a wooden handle fixing clamp 2422. The wooden handle dispensing head 2421 is mounted on the gantry frame and is driven to the wooden handle dispensing position by the wooden handle dispensing drive 2423. It dispenses adhesive onto the contact surface between the wooden handle and the rubber sleeve and injects the adhesive between the wooden handle and the racket shaft through the dispensing hole reserved in the wooden handle. The wooden handle fixing clamp 2422 is mounted on the handle receiving frame 220 and is used to clamp the wooden handle to keep it fixed during the wooden handle dispensing process.

[0124] In this embodiment, the wooden handle, already fitted with the racket shaft, is first securely locked in place by the wooden handle fixing clamp 2422, providing a stable foundation for subsequent precision operations. Then, the wooden handle glue applicator 2421, located on the gantry frame, is driven directly above the pre-drilled glue injection hole on the wooden handle, injecting the glue directly into the cavity formed between the wooden handle and the racket shaft. Compared to the existing method of applying glue to the outer surface of the racket shaft before assembly, this method ensures that the glue thoroughly and evenly fills the entire bonding gap from the inside, effectively eliminating air, avoiding bonding defects, and forming a more complete and robust adhesive layer, directly improving the structural strength and durability of the finished racket.

[0125] See Figures 12 to 14In one embodiment, the wooden handle gluing mechanism 240 further includes a frame rotation assembly 2424, which is mounted on the handle receiving frame 220 and includes a horizontal drive member 24241. A base frame is provided on the movable end of the horizontal drive member 24241, and a rotation drive member 24243 and a rotation gripper 24243 are provided on the base frame. The rotation gripper 24243 is used to clamp the frame and drive the frame to rotate along the shaft axis under the action of the rotation drive member 24243 so as to evenly apply the glue between the wooden handle and the shaft.

[0126] The clamping plate 2241 corresponding to the glue dispensing station of the wooden handle is provided with a groove 22411 for accommodating the racket handle and a follower pulley 22412. When a pair of clamping plates 2241 clamp the racket handle, the racket handle is located in the groove 22411 and rotates and abuts against the follower pulley 22412.

[0127] The support member 222 and clamping member 224 on the fixing component are slidably connected to its base plate 221. When the racket frame rotation assembly 2424 drives the racket frame to rotate, the support member 222 and clamping member 224 on the fixing component slide out of the racket frame under the action of external force.

[0128] After injecting adhesive into the wooden handle through the glue injection hole, relying solely on the natural flow of the adhesive cannot guarantee even coverage. Therefore, this embodiment introduces a dedicated frame rotation assembly 2424. This assembly clamps the frame with its rotating jaws 24243, and the rotation drive 24243 rotates the entire racket along the central axis of the shaft. This rotation spreads the internal liquid adhesive and evenly coats it throughout the entire annular space between the inner wall of the wooden handle and the outer wall of the shaft, thereby eliminating any potential air bubbles or bonding blind spots and ensuring a 360-degree strong bond.

[0129] To achieve this function, in this embodiment, the support member 222 and clamping member 224 at this station are designed to be slidably connected. When the racket frame is transported to this station by the grippers, the support member 222 and clamping member 224 at this station are located in the same position as at other stations, fixing the racket frame in the same way. After the glue is applied to the wooden handle, before the racket frame rotating assembly 2424 begins to apply rotational force, these support members 222 and clamping members 224 are pushed by a motor or other driving device to slide out of the racket frame to avoid interference during rotation.

[0130] To prevent the slender drumstick from wobbling during rotation, a follower pulley 22412 is specially installed on the clamping plate 2241 of this station. When the drumstick is clamped, it rotates and abuts against these pulleys. These pulleys provide a stable, low-friction dynamic support point for the rotating drumstick, ensuring the smoothness and coaxiality of the rotation process, which is a necessary guarantee for achieving uniform glue application.

[0131] In one embodiment, a transfer station is also included, adjacent to the handle glue application station. Located after the handle glue application station, the primary function of this transfer station is to provide an initial curing time. The bonding between the handle and the shaft is crucial to the racket's performance, and the injected adhesive needs time to reach its initial strength. If the racket immediately enters the next handling or processing unit after glue application, internal misalignment may occur due to vibration or external forces, affecting the final quality. The transfer station provides a valuable time window for this critical curing process, ensuring the reliability of the bonding.

[0132] Secondly, this workstation plays a role in "decoupling" and balancing the production cycle. The receiving unit 200 contains multiple intricate steps, and its overall cycle time may not perfectly match that of downstream units (such as the feeding unit 300). As a buffer, the transfer station can effectively prevent the entire production line from stalling due to the long time consumption of a single workstation, thereby smoothing the production process and improving the operating efficiency and throughput of the entire production line.

[0133] See Figures 15-16 An embodiment of this utility model also provides a blanking unit 300 for a carbon fiber badminton racket assembly line. The blanking unit 300 is located at the third station of the assembly line and includes:

[0134] 330 feeder frame;

[0135] The receiving mechanism 340 includes a vertical drive assembly 341 mounted on the unloading frame 330 and a clamping assembly 342 mounted on the vertical drive assembly 341. The clamping assembly 342 moves vertically under the drive of the vertical drive assembly 341 to approach or move away from the feeding robot arm of the receiving unit 200 mounted at the second station of the final assembly line, thereby clamping the carbon fiber badminton racket that has completed the receiving process.

[0136] The testing mechanism 310 is set on the unloading frame 330 and is used to test the flatness and symmetry of the carbon fiber badminton racket after the handle-joining process is completed.

[0137] The material unloading and storage mechanism 320 includes a material pick-and-place component 321, a material placement rack 322, and a waste rack 323. The material pick-and-place component 321 is mounted on the unloading frame 330 and is used to send carbon fiber badminton rackets to the material placement rack 322 or the waste rack 323 according to the test results.

[0138] This embodiment provides a highly integrated unloading unit 300, which integrates the three major functional modules of receiving, inspection, and unloading storage onto an independent unloading frame 330, realizing full automation from the output of the finished product in the previous process to the final quality inspection and sorting. First, by setting up a receiving mechanism 340, the vertical drive component 341 and clamping component 342 work together to automatically and accurately grab rackets with completed handles from the feeding robot arm of the handle unit 200 in the second station, thereby replacing the traditional manual transfer link and ensuring the continuity and stability of the production cycle. Second, the solution includes a dedicated inspection mechanism 310, whose core function is to automatically inspect the flatness and symmetry of the rackets, two key quality indicators. This not only ensures that a uniform and objective quality standard is applied to each product, overcoming the drawbacks of manual inspection being susceptible to subjective factors and inefficient, but also fundamentally guarantees the performance and quality of the finished products. Finally, the setting of the material unloading and storage mechanism 320 enables the unit to automatically send the racket to the qualified product rack 322 or the unqualified product waste bin through the material pick-and-place component 321 according to the results given by the detection mechanism 310. This forms a closed-loop automated system of "detection-feedback-execution", realizing intelligent sorting of products, effectively avoiding the mixing or misplacement problems that may occur in manual sorting, and significantly improving the automation level and management efficiency of the production line.

[0139] See Figure 16 In one embodiment, the receiving mechanism 340 further includes a rotary drive assembly 343 that rotates in the horizontal direction. One end of the rotary drive assembly is disposed on the vertical drive assembly 341, and the other end is used to dispose of the clamping assembly 342.

[0140] In this embodiment, by adding a horizontally rotating drive component to the receiving mechanism 340, the movement flexibility and spatial adaptability of the entire unloading unit 300 are significantly improved. This rotary drive component upgrades the clamping component 342, which could only perform a single vertical lifting motion, into a multi-degree-of-freedom robotic arm structure with horizontal rotation capability. After the receiving mechanism 340 picks up the racket from the previous station, it can actively adjust the racket's posture and direction, rather than simply performing a vertical translation. For example, when there is an angular difference between the feeding posture of the receiving unit 200 and the detection posture of the detection mechanism 310, this rotation function can easily complete the transition, ensuring that the racket is sent into the detection station at the most suitable angle, thereby improving the equipment's adaptability to the production line layout. In addition, this rotation capability also facilitates the subsequent unloading and storage steps, allowing the robotic arm to rotate the racket to the most suitable direction for placement in the storage rack 322 or waste bin, optimizing the movement path, and potentially achieving more efficient storage and retrieval operations in a compact space, enhancing the flexibility and versatility of the entire unit.

[0141] See Figures 17-18 In one embodiment, the detection mechanism 310 includes a drive cylinder 311 disposed on the unloading frame 330. The drive cylinder 311 moves in a vertical direction. A base plate 3111 is disposed on the movable end of the drive cylinder 311. An X-axis detection component 312 and a detection support 313 are disposed on the base plate 3111.

[0142] The X-axis detection assembly 312 includes a detection base plate 3121, a first slide rail 3122 and a first drive member 3123 disposed on the detection base plate 3121. The first slide rail 3122 is horizontally disposed and perpendicular to the axis of the badminton racket. A first detection member 3124 is disposed on the first slide rail 3122. The first drive member 3123 drives the first detection member 3124 to move horizontally along the first slide rail 3122 to detect the symmetry of the racket frame relative to the shaft.

[0143] This embodiment details the specific structure of the detection mechanism 310. First, a vertically moving drive cylinder 311 is used to support the entire detection substrate 3111, achieving the overall lifting function of the detection unit. This allows the detection mechanism 310 to descend and move away from the racket when not in a detection state, and then rise to the detection height when detection is required, ensuring the orderly execution of the detection action and making room for the racket to move in and out.

[0144] Building upon this foundation, the design of the X-axis detection component 312 further ensures the accuracy and reliability of symmetry detection. This component utilizes a first slide rail 3122, perpendicular to the badminton racket's axis, to construct a precise horizontal measurement benchmark. A first drive component 3123 drives the first detection component 3124 to move horizontally along this slide rail, thereby enabling the scanning or positioning of the racket frame's lateral contour. This design simplifies the complex symmetry detection task into a one-dimensional, controllable movement measurement along a pre-set straight line perpendicular to the baseline (racket shaft axis), fundamentally guaranteeing the accuracy and repeatability of the measurement data. Ultimately, it achieves automated, high-precision detection of the racket frame's symmetry relative to the racket shaft—a crucial indicator.

[0145] In one embodiment, the first detection element 3124 is disposed facing the lower surface of the racket frame. The first detection element 3124 is a pair of fiber optic sensors. The pair of fiber optic sensors are connected to the slide rail via a slider 31241. Under the drive of the first driving element 3123, the pair of fiber optic sensors move horizontally synchronously relative to or towards each other along the first slide rail 3122.

[0146] This embodiment further defines the specific implementation of the X-axis detection component 312, resulting in significant technical effects such as high precision, high efficiency, and non-contact measurement. First, the first detection element 3124 is defined as a pair of fiber optic sensors. Utilizing the advantages of high sensitivity, fast response speed, and small spot size of fiber optic sensors, it can accurately capture the edge position of the racket frame at the micrometer level. Simultaneously, non-contact detection is performed facing the lower surface of the racket frame, avoiding scratches or indentations caused by physical contact on the racket surface, and selecting a relatively flat reference surface eliminates interference from other factors such as racket stringing.

[0147] When the two sensors move synchronously towards each other, they can simultaneously approach and detect the edge of the racket frame from both sides. By recording the position information of the two sensors 1321 when they are triggered, the system can not only instantly calculate the actual width of the racket frame, but also directly and efficiently determine the symmetry of the racket frame relative to the center line of motion (i.e., the ideal center line of the racket shaft) by comparing the movement distance or trigger sequence on both sides. This differential synchronous measurement method is more efficient and has stronger anti-interference ability than the method of measuring both sides sequentially by a single sensor 1321, which greatly improves the accuracy and reliability of symmetry detection.

[0148] See Figures 17 to 19 In one embodiment, the detection mechanism 310 further includes a Y-axis detection component 314, which is disposed on the base plate 3111 and includes a lifting base plate 3141, a second slide rail disposed on the lifting base plate 3141, and a second drive member 3142. A second detection member 3143 is disposed on the slide rail, and the second drive member 3143 drives the second detection member 3143 to move vertically along the second slide rail to detect the flatness of the racket frame.

[0149] This embodiment, based on the original symmetry detection, adds a Y-axis detection component 314, giving the detection mechanism 310 a completely new functional dimension, realizing automated and high-precision detection of the racket frame flatness (i.e., flatness and warpage). By setting a dedicated second slide rail and a second drive component 3143, this component can drive the second detection component 3143 to move along a vertical trajectory, thereby scanning or measuring the racket frame's profile in vertical height. If the racket frame has warpage, twisting, or other deformations, the height of various points on its surface will inevitably not be on the same ideal plane. The Y-axis detection component 314 can capture these subtle height deviations through the sensor 1321. This upgrades the unit, which could only perform two-dimensional symmetry detection, into a comprehensive quality inspection platform capable of three-dimensional geometric feature detection, greatly improving the comprehensiveness and reliability of quality control, and ensuring the structural stability and hitting performance of the final product.

[0150] In one embodiment, the second detection element 3143 includes a pair of mounting plates 31431 and a plurality of fiber optic sensors. One end of the mounting plate 31431 is disposed on a slide rail, and the other end is provided with an adjustment plate 31432. The adjustment plate 31432 has an adjustment groove for setting the fiber optic sensors. Under the drive of the second driving element 3143, the pair of mounting plates 31431 move vertically and synchronously relative to each other or towards each other along the first slide rail 3122.

[0151] A fiber optic sensor is centrally located on any one of the adjustment plates 31432, and a pair of fiber optic sensors are provided on the other adjustment plate 31432. The fiber optic sensor of the second detection element 3143 is positioned facing the inner wall of the racket frame.

[0152] First, the device consists of two adjustable plates 31432 that can move synchronously closer to or further away from each other. This synchronous relative movement allows the detection system to actively adapt to racket frames with different inner widths, or to move synchronously from an initial open position and approach the two inner sidewalls of the racket frame until the sensor 1321 is triggered, thereby capturing the inner contour of the racket frame.

[0153] In this embodiment, one fiber optic sensor is mounted on one adjustment plate 31432, and a pair (two) fiber optic sensors are mounted on another adjustment plate 31432. When the device performs detection, these three sensors 1321 will determine three precise measurement points on the inner wall of the racket frame. According to geometric principles, three points can define a plane. This device uses this principle to determine the flatness of the racket frame. For a completely flat racket frame without any distortion, the points detected by the three sensors 1321 should be completely consistent in the vertical coordinates of space, that is, the three points are coplanar (or collinear in a two-dimensional cross-sectional view).

[0154] If the frame is twisted or warped in any way, these three points will not lie on the same ideal plane. For example, if the frame is twisted, the Z-axis (or height) readings of the two sensors 1321 on one side of the adjustment plate 31432 will differ, or their Z-axis heights relative to the single sensor 1321 on the opposite side will deviate. By precisely calculating the spatial coordinates of these three points, the control system can instantly determine whether the frame is twisted or deformed and the severity of the deformation.

[0155] The adjustment plate 31432 has an adjustment slot for setting the fiber optic sensor, which brings good adjustability and versatility to the entire detection system. It facilitates quick model change and accurate calibration for rackets of different models and frame types, and enhances the flexibility of the equipment.

[0156] See Figure 18 and 20In one embodiment, the detection mechanism 310 further includes a frame rotation assembly 315, which is mounted on the unloading frame 330 and includes a horizontal drive member 3151. A base frame is provided on the movable end of the horizontal drive member 3151, and a rotation drive member 3152 and a rotation gripper 3153 are provided on the base frame. The rotation gripper 3153 is used to clamp the frame and drive the frame to rotate along the axis of the racket shaft under the action of the rotation drive member 3152.

[0157] The clamping assembly 342 includes a pair of detection clamps 3421. The detection clamps 3421 are provided with clamping grooves 34211 for accommodating the paddle and clamping follower pulleys 34212. When the pair of detection clamps 3421 clamp the paddle, the paddle is located in the clamping grooves 34211 and rotates and abuts against the clamping follower pulleys 34212.

[0158] This embodiment introduces a racket frame rotation assembly 315 and achieves omnidirectional, multi-angle scanning and detection of the badminton racket through the clamping assembly 342. Firstly, by adding a racket frame rotation assembly 315 that clamps the racket frame and rotates it along the shaft axis, the detection mechanism 310 is no longer limited to detecting a single static cross-section of the racket. After the X-axis and Y-axis detection assemblies 314 complete one measurement, the racket frame can be rotated by a specific angle (e.g., 90 degrees) before the next measurement. By repeating this process, the system can acquire symmetry and flatness data of the racket frame at any position on the entire circumference, thereby constructing a more complete three-dimensional profile, greatly improving the comprehensiveness of the detection, and enabling the discovery of hidden defects such as warping or asymmetry that only appear at specific angles.

[0159] Secondly, the clamping assembly 342 and the rotating assembly work together. The clamping assembly 342 has a pair of detection clamps 3421 with clamp grooves 34211 for accommodating the racket shaft and clamp follower pulleys 34212. When the clamping assembly 342 clamps the racket shaft, the racket is firmly positioned at the detection station; while when the racket frame rotating assembly 315 drives the racket frame to rotate, the racket shaft can rotate freely on the clamp follower pulleys 34212 with minimal friction, ensuring stability and accuracy during the dynamic rotation scanning process.

[0160] See Figure 21 and 22 In one embodiment, the material rack 322, the waste rack 323 and the receiving mechanism 340 are arranged in the same line. The material pick-and-place assembly 321 includes a ground rail 3211 and a material pick-and-place robotic arm 3212 arranged on the ground rail 3211. The ground rail 3211 is parallel to the line where the material rack 322, the waste rack 323 and the receiving mechanism 340 are located. The material pick-and-place robotic arm 3212 moves along the ground rail 3211 to pick up the racket on the receiving mechanism 340 and send it to the waste rack 323 or the material rack 322.

[0161] This embodiment constructs a highly efficient, long-distance, and highly stable automated material handling and sorting system. By arranging the placement rack 322, waste rack 323, and receiving mechanism 340 colinearly and configuring a parallel ground rail 3211, this design simplifies the complex material transfer task into a linear reciprocating motion in a single dimension. The picking and placing robotic arm 3212, mounted on the ground rail 3211, only needs to move along this straight ground rail 3211 to cover all positions from the picking point (receiving mechanism 340) to the two placement points (placement rack 322 and waste rack 323). The movement path is clear and the control is simple, greatly improving handling efficiency and positioning accuracy. Compared with fixed or articulated robots, the ground rail 3211 robotic arm system has the advantages of high movement speed, large stroke range, and stable and reliable structure. It is particularly suitable for application scenarios on the production line that require sorting products from a single workstation to different storage areas, and also provides good scalability for future production line expansion, adding more racks, or extending the handling distance.

[0162] In one embodiment, the scrap rack 323 is connected to the unloading frame 330 via a lifting assembly 350. The scrap rack 323 includes a pull-out base plate 3231 and baffles 3232 disposed on both sides of the pull-out base plate 3231. The baffles 3232 and the pull-out base plate 3231 together form a space for accommodating scrap rackets. The scrap rack 323 moves up and down under the drive of the lifting assembly 350 to move closer to or away from the loading / unloading robotic arm 3212.

[0163] The pull-out base plate 3231 of the scrap rack 323 is slidably connected to the lifting assembly 350. Under the action of external force, the scrap rack 323 moves away from the lifting assembly 350 in the horizontal direction to remove the scrap racket inside the scrap rack 323.

[0164] In this embodiment, firstly, the waste rack 323 is connected to the unloading frame 330 via the lifting assembly 350 and can move up and down under its drive. This design allows the waste rack 323 to actively adjust its height to move closer to or further away from the picking and placing robotic arm 3212. When the robotic arm disposes of waste, the waste rack 323 can rise to a higher receiving height, shortening the movement stroke of the robotic arm, improving the disposing efficiency and stability, and effectively avoiding secondary damage that may be caused by excessive disposing distance. Secondly, the waste rack 323, together with the pull-out base plate 3231 and the baffles 3232 on both sides, forms a receiving space, ensuring that the waste rackets can be collected securely and preventing them from scattering outside the machine.

[0165] The pull-out base plate 3231 of the scrap rack 323 is slidably connected to the lifting assembly 350. When it is necessary to empty the scrap rack, the operator only needs to apply external force to pull out the base plate 221, which carries all the scrap rackets, horizontally like a drawer, away from the machine body. This function greatly simplifies the scrap emptying operation, eliminating the need for the operator to bend over and enter the machine, saving time and effort, improving operational safety, and significantly enhancing the human-machine interaction experience of the equipment.

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.

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.
