Description

Technical Field

[0001] The invention relates to the technical field of carbon fiber badminton racket manufacturing, in particular to a carbon fiber badminton racket assembly production line and a blanking unit thereof. Background Art

[0002] With the rapid development of carbon fiber composite molding technology and the sporting goods manufacturing industry, high-performance carbon fiber badminton rackets with extremely demanding performance requirements have emerged on the market. To achieve ultimate aerodynamic performance and striking stability, these rackets demand stringent micron-level geometric precision, including frame symmetry and flatness. After the critical assembly step of bonding the shaft to the cone cap and handle—the final assembly—the finished product must undergo quality inspection. Consequently, an operating unit has been developed on the production line to inspect and sort the rackets after they have been attached to the handle.

[0003] In traditional technology, the most basic processing method is for the production line workers to manually remove the badminton rackets from the workstations, and manually connect the handles, apply glue and assemble them. In order to solve the problem of low efficiency of pure manual operation, some automated handle connection equipment has emerged in the industry, such as a badminton racket automatic handle connection machine disclosed in the Chinese utility model patent (authorization announcement number CN222173012U). The device adopts a rotating disk structure (a first connecting disk and a second connecting disk) containing multiple stations. While the handle connection operation is being performed at one station, the finished product can be picked up and placed and new materials can be loaded at other stations, thereby realizing continuous handle connection. At the same time, it is also equipped with an automatic glue coating roller brush to replace the manual gluing link, further improving the degree of automation and efficiency of the handle connection process.

[0004] However, whether using the aforementioned automatic handle-joining machine or the more traditional, purely manual method, common problems still exist in the handling of finished products after the handle is joined. First, existing automated handle-joining equipment focuses solely on the "assembly" phase and lacks the ability to perform quality inspections on finished products. After the product leaves the production line, it still needs to be transferred to an independent workstation for additional manual quality inspection, which disrupts the smooth flow of automated production. Secondly, due to the lack of integrated online inspection capabilities, the subsequent distinction and sorting of qualified and unqualified products can only be completed manually, making it impossible to achieve true full-process automation, resulting in limited overall production efficiency. The final quality control link is still subject to the subjective factors of manual inspection and cannot meet the strict geometric accuracy requirements of high-performance rackets. Summary of the Invention

[0005] Based on this, it is necessary to provide a carbon fiber badminton racket assembly production line and a blanking unit thereof to address the above problems.

DETAILED DESCRIPTION

[0041] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0042] See Figure 1 and Figure 2An embodiment of the present invention provides a blanking unit for a carbon fiber badminton racket assembly line. The blanking unit is arranged at the third workstation of the assembly line, and the blanking unit includes: a frame 100; a feeding mechanism 200, which includes a vertical driving assembly 210 arranged on the frame 100, and a clamping assembly 220 arranged on the vertical driving assembly 210. The clamping assembly 220 moves in a vertical direction under the drive of the vertical driving assembly 210 to approach or move away from a feeding robot arm of a handle unit arranged at the second workstation of the assembly line, thereby clamping a carbon fiber badminton racket that has completed the handle connection process; a detection mechanism 300, which is arranged on the frame 100 and is used to detect the flatness and symmetry of the carbon fiber badminton racket that has completed the handle connection process; a blanking storage mechanism 400, which includes a material taking and placing assembly 410, a material rack 420 and a waste rack 430. The material taking and placing assembly 410 is arranged on the frame 100 and is used to send the carbon fiber badminton racket to the material rack 420 or the waste cabinet according to the detection results.

[0043] This embodiment provides a highly integrated material removal unit, which integrates the three functional modules of material receiving, testing, and material storage into an independent frame 100, thereby realizing the automation of the entire process from the output of the finished product of the previous process to the final quality inspection and sorting. First, by setting up a material receiving mechanism 200, and utilizing the coordinated work of its vertical drive component 210 and the clamping component 220, it is possible to automatically and accurately grab the racket with the completed handle from the feeding robot arm of the handle unit at the second workstation, thereby replacing the traditional manual transfer link and ensuring the continuity and stability of the production rhythm. Secondly, a special detection mechanism 300 is set up in the scheme, and its core function is to automatically detect the two key quality indicators of the flatness and symmetry of the racket. This not only ensures that a unified and objective quality standard can be implemented for each product, overcomes the disadvantages of manual detection that is easily affected by subjective factors and inefficient, but also fundamentally guarantees the performance and quality of the products leaving the factory. Finally, the setting of the unloading storage mechanism 400 enables the unit to automatically send the rackets to the storage rack 420 for qualified products or the waste cabinet for unqualified products through the material taking and discharging component 410 according to the results given by the detection mechanism 300, forming a "detection-feedback-execution" closed-loop automation system, realizing intelligent sorting of products, effectively avoiding the problems of mixing or misplacing that may occur in manual sorting, and significantly improving the automation level and management efficiency of the production line.

[0044] See Figure 3 In one embodiment, the material receiving mechanism 200 further includes a rotary drive assembly 230 that rotates in a horizontal direction. One end of the rotary drive assembly 230 is disposed on the vertical drive assembly 210 , and the other end is used to set the clamping assembly 220 .

[0045] In this embodiment, the addition of a horizontally rotating rotary drive assembly 230 to the material receiving mechanism 200 significantly enhances the overall flexibility and spatial adaptability of the unloading unit. This rotary drive assembly 230 upgrades the clamping assembly 220, which previously only performed a single vertical lifting motion, into a multi-degree-of-freedom robotic arm structure with horizontal rotation capabilities. After grasping a racket from the previous station, the material receiving mechanism 200 can actively adjust the racket's posture and orientation, rather than simply performing vertical translation. For example, when there is an angular difference between the feeding position of the receiving unit and the inspection position of the inspection mechanism 300, this rotation function can easily facilitate the transition and ensure that the racket is delivered to the inspection station at the optimal angle, thereby improving the device's adaptability to production line layouts. Furthermore, this rotation capability facilitates subsequent unloading and storage steps, allowing the robotic arm to rotate the racket to the optimal orientation for placement in the storage rack 420 or waste bin, optimizing the motion path and potentially enabling more efficient storage and retrieval operations within a compact space, enhancing the flexibility and versatility of the entire unit.

[0046] See Figures 3 to 6 In one embodiment, the detection mechanism 300 includes a driving cylinder 310 disposed on the frame 100. The driving cylinder 310 moves in a vertical direction. A base plate 320 is disposed on the movable end of the driving cylinder 310. The base plate 320 is provided with an X-axis detection assembly 330 and a detection support 340.

[0047] The X-axis detection assembly 330 includes a detection base plate 331, a first slide rail 332 disposed on the detection base plate 331, and a first driving member 333. The first slide rail 332 is disposed horizontally and perpendicular to the axis of the badminton racket. A first detection member 334 is disposed on the first slide rail 332. The first driving member 333 drives the first detection member 334 to move horizontally along the first slide rail 332 to detect the symmetry of the racket frame relative to the racket shaft.

[0048] This embodiment details the specific structure of the detection mechanism 300. First, a vertically movable drive cylinder 310 supports the entire detection base plate 320, enabling the entire detection unit to be raised and lowered. This allows the detection mechanism 300 to be lowered away from the racket when not in use and raised to the detection height when needed, ensuring orderly detection and allowing room for the racket to enter and exit.

[0049] On this basis, the design of the X-axis detection assembly 330 further ensures the accuracy and reliability of symmetry detection. This assembly utilizes a first slide rail 332, positioned perpendicular to the axis of the badminton racket, to create a precise horizontal measurement reference. A first drive member 333 drives a first detection member 334 in horizontal motion along this slide rail, thereby enabling the scanning or positioning of the lateral profile of the racket frame. This design simplifies the complex task of symmetry detection into a one-dimensional, controllable motion measurement along a preset line perpendicular to the reference line (the racket shaft axis), fundamentally ensuring the accuracy and repeatability of the measurement data, ultimately achieving automated, high-precision detection of the key indicator of racket frame symmetry relative to the racket shaft.

[0050] See Figures 3 to 6 In one embodiment, the first detecting member 334 is arranged toward the lower surface of the racket frame. The first detecting member 334 is a pair of optical fiber sensors 500. The pair of optical fiber sensors 500 are connected to the slide rail through a slider. Driven by the first driving member 333, the pair of optical fiber sensors 500 move horizontally and synchronously relative to or toward each other along the first slide rail 332.

[0051] This embodiment further defines the specific implementation of the X-axis detection assembly 330, achieving the remarkable technical benefits of high-precision, high-efficiency, and non-contact measurement. First, the first detection element 334 is defined as a pair of fiber optic sensors 500. Leveraging their high sensitivity, fast response speed, and small spot size, they are capable of accurately capturing the edge of the racket frame with micron-level precision. Furthermore, non-contact detection directed toward the lower surface of the racket frame prevents scratches or indentations caused by physical contact, while also providing a relatively flat reference surface, eliminating interference from factors such as stringing.

[0052] When the two sensors move synchronously toward 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 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 moving centerline (i.e., the ideal centerline of the racket shaft) by comparing the movement distance or trigger timing on both sides. This differential, synchronous measurement method is more efficient and has stronger interference resistance than a single sensor measuring both sides sequentially, greatly improving the accuracy and reliability of symmetry detection.

[0053] See Figure 7 and Figure 8In one embodiment, the detection mechanism 300 further includes a Y-axis detection assembly 350, which is disposed on the substrate 320 and includes a lifting base plate 351, a second slide rail disposed on the lifting base plate 351, and a second driving member 352. A second detection member is provided on the slide rail, and the second driving member 352 drives the second detection member to move vertically along the second slide rail to detect the flatness of the racket frame.

[0054] Based on the original symmetry detection, this embodiment gives the detection mechanism 300 a new functional dimension by adding a Y-axis detection component 350, realizing the automated and high-precision detection of the flatness (i.e., flatness and warpage) of the racket frame. By setting a dedicated second slide rail and a second drive member 352, the component can drive the second detection member to move along a vertical track, so that the outline of the racket frame in vertical height can be scanned or measured. If the racket frame has deformations such as warping and twisting, the heights of various points on its surface will inevitably not be in the same ideal plane, and the Y-axis detection component 350 can capture these subtle height deviations through sensors. This upgrades the unit that was originally only able to perform two-dimensional symmetry detection to 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.

[0055] See Figure 7 and Figure 8 In one embodiment, the second detection member includes a pair of mounting plates 353 and a plurality of optical fiber sensors 500. One end of the mounting plate 353 is disposed on the slide rail, and the other end is provided with an adjustment plate 354. The adjustment plate 354 has an adjustment slot for disposing the optical fiber sensor 500. Driven by the second driving member 352, the pair of mounting plates 353 move vertically and synchronously relative to or toward each other along the first slide rail 332.

[0056] One optical fiber sensor 500 is centrally disposed on any adjustment plate 354 , and a pair of optical fiber sensors 500 are disposed on the other adjustment plate 354 . The optical fiber sensor 500 of the second detection member is disposed toward the inner wall of the racket frame.

[0057] First, the device consists of two adjustment plates 354 that can be moved synchronously toward or away from each other. This synchronized relative movement allows the detection system to actively adapt to racket frames of varying internal widths, or, from an initially open position, synchronously move and approach the two inner walls of the racket frame until the sensor is triggered, thereby accurately "capturing" the inner contour of the racket frame.

[0058] In this embodiment, one fiber optic sensor 500 is mounted on one adjustment plate 354, while a pair (two) of these sensors 500 are mounted on the other adjustment plate 354. When the device performs a test, these three sensors determine three precise measurement points on the inner wall of the racket frame. According to geometric principles, three points define a plane. This device utilizes this principle to determine the flatness of the racket frame. For a perfectly flat, undistorted racket frame, the points detected by these three sensors should be perfectly aligned in their vertical coordinates—that is, coplanar (or collinear in a two-dimensional cross-section).

[0059] If the frame exhibits any distortion or warping, these three points will not lie in the same ideal plane. For example, if the frame is twisted, the Z-axis (or height) readings of the two sensors on one side of the adjustment plate 354 will differ, or their Z-axis heights will be offset relative to the single sensor on the opposite side. By precisely calculating the spatial coordinates of these three points, the control system can instantly determine the presence and severity of frame distortion.

[0060] The adjustment plate 354 is provided with an adjustment slot for setting the optical fiber sensor 500, which brings good adjustability and versatility to the entire detection system, facilitates rapid replacement and precise calibration of rackets of different models and frame types, and enhances the flexibility of the equipment.

[0061] See Figure 9 In one embodiment, the detection mechanism 300 further includes a racket frame rotating assembly 360. The racket frame rotating assembly 360 is disposed on the frame 100 and includes a horizontal driving member 361. A base 362 is disposed on a movable end of the horizontal driving member 361. The base 362 is provided with a rotating driving member 363 and a rotating clamp 364. The rotating clamp 364 is used to clamp the racket frame and, under the action of the rotating driving member 363, drives the racket frame to rotate along the axis of the racket shaft.

[0062] The clamping assembly 220 includes a pair of clamping plates 221 , each of which is provided with a groove 222 for accommodating the racket rod and a follower pulley 223 . When the pair of clamping plates 221 clamp the racket rod, the racket rod is located in the groove 222 and is in rotational contact with the follower pulley 223 .

[0063] This embodiment introduces a frame rotation assembly 360, and through the clamping assembly 220, enables all-round, multi-angle scanning inspection of badminton rackets. First, by adding a frame rotation assembly 360 capable of clamping the racket frame and rotating it along the racket shaft axis, the inspection mechanism 300 is no longer limited to inspecting a single static cross-section of the racket. After the X-axis and Y-axis inspection assemblies 350 complete a 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 obtain symmetry and flatness data for any position along the entire circumference of the racket frame, thereby constructing a more complete three-dimensional profile. This greatly improves the comprehensiveness of the inspection and can detect hidden defects such as warping or asymmetry that only appear at specific angles.

[0064] Secondly, the clamping assembly 220 works in conjunction with the rotating assembly. A pair of clamping plates 221 of the clamping assembly 220 are equipped with a groove 222 for accommodating the shaft and a follower pulley 223. When the clamping assembly 220 clamps the shaft, the racket is securely positioned in the inspection station. Furthermore, when the frame rotating assembly 360 rotates the frame, the shaft can rotate freely on the follower pulley 223 with minimal friction, ensuring stability and accuracy during dynamic rotational scanning.

[0065] See Figure 2 、 Figure 10 and Figure 11 In one embodiment, the material rack 420, the waste rack 430 and the material receiving mechanism 200 are arranged in the same line, and the material picking and placing assembly 410 includes a ground rail 411 and a material picking and placing robot arm 412 arranged on the ground rail 411. The ground rail 411 is parallel to the straight line where the material rack 420, the waste rack 430 and the material receiving mechanism 200 are located. The material picking and placing robot arm 412 moves along the ground rail 411 to clamp the racket on the material receiving mechanism 200 and send it to the waste rack 430 or the material rack 420.

[0066] This embodiment constructs an efficient, long-distance, and highly stable automated material handling and sorting system. By arranging the material rack 420, the waste rack 430, and the material receiving mechanism 200 in a colinear manner and configuring a parallel ground rail 411, this design simplifies the complex material transfer task into a linear reciprocating motion in a single dimension. The material picking and unloading robot 412, which is set on the ground rail 411, only needs to move along this linear ground rail 411 to cover all positions from the material picking point (the material receiving mechanism 200) to the two material unloading points (the material rack 420 and the waste rack 430). The motion path is clear and the control is simple, which greatly improves the handling efficiency and positioning accuracy. Compared with fixed or articulated robots, the ground rail 411 type robot arm system has the advantages of fast movement speed, large travel range, and stable and reliable structure. It is particularly suitable for application scenarios on the production line where products need to be sorted from a single workstation to different storage areas. It also provides good scalability for future production line expansion, adding more material racks, or extending the handling distance.

[0067] See Figure 12 In one embodiment, the waste rack 430 is connected to the frame 100 via a lifting assembly 440. The waste rack 430 includes a drawer bottom plate 431 and baffles 432 disposed on both sides of the drawer bottom plate 431. The baffles 432 and the drawer bottom plate 431 together form a space for accommodating waste rackets. The waste rack 430 moves up and down under the drive of the lifting assembly 440 to approach or move away from the material picking and placing robot arm 412.

[0068] The drawer bottom plate 431 of the waste rack 430 is slidably connected to the lifting assembly 440 . Under the action of external force, the waste rack 430 moves horizontally away from the lifting assembly 440 to remove the waste rackets in the waste rack 430 .

[0069] In this embodiment, first, the waste rack 430 is connected to the frame 100 through the jacking assembly 440, and can move up and down under the drive thereof. This design allows the waste rack 430 to actively adjust its own height to get closer to or away from the material picking and placing robot arm 412. When the robot arm puts waste, the waste rack 430 can rise to a higher receiving height, shortening the movement stroke of the robot arm, improving the delivery efficiency and stability, and effectively avoiding secondary damage that may be caused by the delivery distance being too high. Secondly, the waste rack 430 is formed by a pull-out bottom plate 431 and baffles 432 on both sides to form a accommodating space, ensuring that the waste rackets can be safely collected and prevented from being scattered outside the machine.

[0070] The pull-out base plate 431 of the waste rack 430 is slidably connected to the lifting assembly 440. To empty the waste, the operator simply applies force and pulls the base plate, holding all the waste rackets, horizontally outward, like a drawer, away from the machine. This feature greatly simplifies the waste emptying operation, eliminating the need for the operator to bend down and reach deep into the machine. This saves time and effort, improves operator safety, and significantly enhances the user-interaction experience.
