DETAILED DESCRIPTION

[0019] The present application is described in further detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the present application and cannot be understood as limiting the scope of protection of the present application. Technicians in this field can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] Example 1 In order to solve the problems in the existing sleeve pattern making process, pattern design and optimization mainly rely on manual experience and static testing, which is generally a single-station mode and cannot realize parallel verification of multiple solutions. The pattern making efficiency is extremely low and it is difficult to meet the needs of high-frequency and refined modification. Figure 1-Figure 4 The present invention provides a method for making and sewing a pattern of a down jacket sleeve, comprising the following steps: S1. Provide a plate-making device, comprising a plate-making table 1, a plate-making assembly 2 disposed on top of the plate-making table 1, a multi-station testing assembly 3 disposed on one side of the plate-making assembly 2, and a simulation assembly 4; The plate-making assembly 2 includes a frame 201, a two-dimensional plate-making platform 202 provided on the bottom surface of the frame 201, a projector 203 and a scanner 204 provided on the top surface of the frame 201, and an RFID identification unit; The multi-station test assembly 3 includes a rotating unit 301 and a plurality of arm units 302 evenly distributed around the rotating unit 301; S2, putting the completed sleeve with filling on any arm unit 302; S3. Control the rotation unit 301 to drive the arm unit 302 into the simulation component 4, apply dynamic airflow to the sleeve, and simulate different wearing states in combination with the movement of the arm unit 302 itself to obtain the shape data of the sleeve in different states; S4: When correcting the sleeve pattern, the rotation unit 301 is controlled to rotate the corresponding arm unit 302 in front of the pattern maker. At the same time, the RFID recognition unit reads the sewing information of the sleeve carried by the arm unit 302, and the projector 203 projects the current sewing path in real time onto the two-dimensional pattern making platform 202 below. The pattern maker adjusts the stitching path based on the acquired morphological data and projection path, and gradually optimizes the sleeve pattern through cyclic testing and path correction of multiple arm units 302 until the ideal sleeve pattern required by the design is achieved.

[0021] The plate-making component 2 also includes a display screen 205 provided on the back side of the two-dimensional plate-making platform 202. The display screen 205 is used to display the morphological data of the sleeves in different states, and its lower end is rotatably connected to the plate-making table 1, including information such as stitching path, wrinkle distribution, and filling uniformity, which is convenient for plate-making personnel to observe and analyze.

[0022] The rotating unit 301 includes a rotating frame 301a and two bearing seats 301b arranged at both ends of the rotating frame 301a. The bearing seats 301b are used to support the rotating shaft of the rotating frame 301a to achieve stable rotation of the rotating frame 301a; the arm unit 302 includes a mounting frame 302a fixed on the surface of the rotating frame 301a and an arm model 302b rotatably arranged in the mounting frame 302a. One end of the arm model 302b is provided with a motor 302c for driving it to rotate, and the end of the mounting frame 302a facing away from the rotating frame 301a is provided with a handle 302d, which is used to pull the arm unit 302 to rotate.

[0023] The arm model 302b is an electric model with multiple driving joints integrated inside. It can simulate basic movements of the human arm such as bending, stretching, and rotation, and more realistically restore the dynamic performance of the sleeve in the actual wearing state. In order to adapt to the needs of different age groups and different body shapes, the device is equipped with arm models 302b of various specifications, including children's model, youth model, adult male model and adult female model. Each specification of arm model 302b has detailed distinctions in key dimensions such as arm length, arm circumference, and arm curvature to meet diverse pattern making needs.

[0024] The RFID identification unit includes an RFID reader / writer 207 and an RFID tag 302 e correspondingly arranged on the side of each mounting bracket 302 a. The RFID reader / writer 207 is fixed on the side of the positioning plate 206 in the frame 201.

[0025] like Figure 3 、 Figure 5 As shown, a positioning hole 302f is provided on the side of the mounting bracket 302a, and a positioning member 208 is provided on the positioning plate 206. The positioning member 208 cooperates with the positioning hole 302f to lock the multi-station test assembly 3. The positioning member 208 includes a fixed base 208a, a positioning rod 208b that is movable and extends through the fixed base 208a, and a spring 208c that is sleeved on the positioning rod 208b. One end of the spring 208c is fixedly connected to the fixed base 208a, and the other end is fixedly connected to the positioning rod 208b. The positioning rod 208b is plugged into the positioning hole 302f. When locking is required, the positioning rod 208b is pulled, and the spring 208c is stretched. Then the positioning rod 208b is released. Under the restoring force of the spring 208c, the positioning rod 208b is inserted into the corresponding positioning hole 302f on the mounting bracket 302a, achieving precise positioning.

[0026] A rotatable multi-station test assembly 3 is used to achieve efficient cycle testing of multiple sets of sleeves, significantly shortening the plate making cycle. One or more RFID tags 302e are set on the side of each arm unit 302. The RFID tag 302e stores the sewing information of the sleeve set thereon, such as the sample number, stitch path data, sewing personnel, etc. When the arm unit 302 rotates to the side of the frame 201, the positioning piece 208 cooperates with the positioning hole 302f to lock the rotation. At this time, the RFID reader 207 automatically identifies the RFID tag 302e and reads the corresponding data. The acquired data is processed by the system, such as a common computer system, and the projector 203 is controlled to project the stitching path of the sleeve to the two-dimensional printing plate below in real time. On the plate platform 202; the introduction of the RFID identification system improves the level of intelligence. By quickly retrieving the stitching path data of the corresponding arm unit 302, the projection path can be quickly loaded. The plate maker can cut and sew according to the projection path, which significantly improves the accuracy of the stitching position and further improves the efficiency and accuracy of plate making. During multi-station cycle testing, each time a new arm unit 302 is switched, the projection system automatically and synchronously updates the corresponding pattern data. The RFID identification system realizes a one-to-one correspondence between the stitching path and the sample information, effectively avoiding the data misalignment problem that may occur during manual recording and operation, and reducing the time consumption in the plate making process. Especially when the pattern needs to be modified multiple times, the advantage is more obvious.

[0027] Example 2 On the basis of the first embodiment, in order to move the arm model 302b to the top of the two-dimensional plate making platform 202 for observation, as shown in FIG. Figure 3 As shown, a mounting plate 302g is rotatably provided in the mounting frame 302a, and a knob 302h for locking the mounting plate 302g is provided on the top of the mounting frame 302a; the arm model 302b is rotatably provided on the mounting plate 302g, and the motor 302c is fixed on the mounting plate 302g.

[0028] Loosen the knob 302h, and the mounting plate 302g can now rotate freely in the mounting frame 302a, and move the arm model 302b to the top of the two-dimensional platemaking platform 202. By adjusting the angle of the mounting plate 302g, the spatial posture of the arm model 302b can be flexibly adjusted for observation by the platemaking personnel, thereby facilitating platemaking.

[0029] Example 3 On the basis of the first and second embodiments, in order to truly restore the stress and deformation of the sleeve in different states, more accurate data support is provided for the optimization of the sewing path, such as Figure 6-Figure 8As shown, the simulation component 4 is used to simulate the dynamic airflow of the sleeves, including a main box 401 fixed on the top of the plate-making table 1, two movable boxes 402 symmetrically arranged on both sides of the main box 401, and a translation mechanism 403 installed on the back side of the main box 401. The translation mechanism 403 is used to drive the two movable boxes 402 to move horizontally synchronously to open an opening for the arm unit 302 to enter and exit; a blowing simulation unit 404 is provided on one side of the interior of the main box 401, and a leveling unit 405 and an air outlet 407 are provided on the other side of the interior. A purification cylinder 408 is provided at the air outlet 407, and a data acquisition unit 406 is provided on the top surface of the movable box 402.

[0030] The blowing simulation unit 404 includes a fan 404a, a deflector 404b is fixedly provided at the outlet of the fan 404a, and a porous plate 404c for evenly distributing the airflow is fixedly provided inside the deflector 404b to ensure that the airflow evenly covers the surface of the sleeve and simulates the wind force in a real wearing environment; the flattening unit 405 includes an electric push rod 405a, a curved plate 405b is fixedly provided at the movable end of the electric push rod 405a, and a plurality of rollers 405c are rotatably provided inside the curved plate 405b, which can automatically smooth the sleeve after the airflow simulation and restore the initial shape to facilitate the next round of testing; the data acquisition unit 406 includes a camera 406a and a plurality of fill lights 406b arranged around the camera 406a. The rotation of the arm unit 302 cooperates with the camera 406a to comprehensively collect images of the sleeve's shape changes, capture details of the sleeve in various bending states, and combine the image recognition algorithm to analyze the rationality of the stitching path, the distribution of wrinkles and the filling effect, and form visual data feedback to the display screen 205.

[0031] The above-described embodiments merely illustrate several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention.
