Description
Technical Field
[0001] This utility model relates to the field of suture management technology, and in particular to an automatic suture imaging clarity adjustment device, and an intelligent suture cabinet using the automatic suture imaging clarity adjustment device. Background Technology
[0002] When garment factories produce sample garments, sample makers need to match the corresponding color of thread to the sample fabric in a sample room. However, in medium to large sample rooms, there are numerous sample makers, ranging from a hundred to several hundred; and there are hundreds or even thousands of thread options to choose from. This leads to the following problems:
[0003] I. Color Matching: Sample garment makers rely on experience to find the seam color that matches the sample fabric, which is time-consuming and labor-intensive. Furthermore, the variety of seam types and colors, coupled with differences in color perception among individuals, means that different sample garment makers may find different seams for the same piece of sample fabric, leading to inconsistencies in sample garment production standards. Additionally, manual color matching results are also affected by the employee's mood, ambient lighting, and external light conditions. If the employee is wearing highly reflective clothing, the color matching results will also be affected.
[0004] II. Regarding sewing threads: There is no unified management of sewing threads, or management has only just begun. If employees accidentally fail to return the sewing threads to their original storage location, it will cause time and effort to retrieve the threads next time. In addition, the storage of other sewing threads will soon become chaotic, making it impossible for sewing thread managers to know the specific storage location of various sewing threads. Consequently, it is impossible to replenish the stock of sewing threads in a timely manner, which brings many uncertainties to the production of sample garments and affects and restricts the efficiency of sample garment production.
[0005] To address the aforementioned issues, a smart sewing cabinet has emerged. This smart sewing cabinet can detect the color information of fabric pieces or sewing threads through a visual color matching system and automatically and accurately locate the corresponding sewing thread stored in the sewing thread storage cabinet. This avoids deviations in the color of the sewing thread found due to the user's skill level and visual parallax, thereby significantly improving the consistency of sample garment production, saving a lot of thread-finding time, increasing sample garment production efficiency, and reducing the skill requirements for workers.
[0006] However, visual color matching systems rely on high-definition cameras to identify the color of the object being measured and collect color data. This requires different objects to be kept at the same reference height. Since the size and height of the seams used in different sample rooms vary, and the focal length of the camera in the visual color matching system is fixed and cannot be adjusted, the smart seam cabinet using the visual color matching system has poor versatility in different sample rooms.

The electric lifting assembly is fixed on the top plate and drives the movable frame to move along the linear guide columns through the drive end.
[0013] Preferably, the movable frame is equipped with linear bearings, and the movable frame is sleeved on two linear guide posts through the linear bearings.
[0014] Preferably, the electric lifting assembly includes a rack and a motor. The rack is vertically arranged and fixedly connected to the movable frame. The motor is fixed to the top plate and meshes with the rack through gears. The motor is connected to the controller of the intelligent sewing cabinet via a signal.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0019] When using the automatic adjustment device for the clarity of sewing images of this utility model, the sewing thread needs to be placed below the fixed-focus camera first. Then, the controller of the intelligent sewing cabinet can drive the electric lifting component to automatically adjust the relative distance between the fixed-focus camera and the sewing thread, so as to adjust the image clarity. This makes it convenient for the intelligent sewing cabinet to quickly read and identify the color of the object being tested in different sample rooms.
[0020] This utility model's intelligent stitch cabinet, employing the aforementioned automatic stitch image clarity adjustment device, allows for continuous image acquisition of stitches after they are placed in the stitch detection area using a fixed-focus camera. Simultaneously, the controller adjusts the height of the fixed-focus camera by raising and lowering the electric lifting component based on the clarity of the stitch images captured by the camera. By comparing the clarity of stitch images acquired at different heights, the optimal fixed-focus camera height for stitch image clarity is determined. At this height, the optimal clarity stitch image is captured and saved. The controller then determines the effective area of the image, automatically cuts out and retains the effective image, calculates the image color RGB values, and compares them with the RGB values of all stitches in the database. The three stitches with the smallest color difference are then selected and their data are displayed on the screen. Attached Figure Description

[0044] Furthermore, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.
[0045] See Figures 1 to 4 This embodiment provides an automatic adjustment device for the clarity of sewing footage, including a fixed frame 1, an electric lifting assembly, a movable frame 2, and a fixed-focus camera 3. The fixed frame 1 is installed on the intelligent sewing cabinet, the electric lifting assembly is set on the fixed frame 1, the movable frame 2 is set on the drive end of the electric lifting assembly, and the fixed-focus camera 3 is fixed on the movable frame 2. The electric lifting assembly can drive the fixed-focus camera 3 to move in the vertical direction. Both the electric lifting assembly and the fixed-focus camera 3 are connected to the controller signal of the intelligent sewing cabinet.
[0046] In this embodiment, the automatic adjustment device for the clarity of sewing images requires the sewing thread to be placed below the fixed-focus camera 3. Then, the controller of the intelligent sewing cabinet can drive the electric lifting component to automatically adjust the relative distance between the fixed-focus camera 3 and the sewing thread, thereby adjusting the image clarity. This allows the intelligent sewing cabinet to quickly read and identify the color of the object being tested in different sample rooms.
[0047] Preferably, in this embodiment, the controller of the intelligent sewing cabinet is a PLC.
[0048] Preferably, see Figures 1 to 4Photoelectric sensors 6 are fixed at the upper and lower limit positions of the mobile frame 2. A displacement detection rod 7, which is used in conjunction with the photoelectric sensor 6, is installed on the mobile frame 2. The photoelectric sensor 6 is connected to the controller signal of the intelligent sewing cabinet.
[0049] The two photoelectric sensors 6 can determine the upper and lower limits of the travel of the moving frame 2, ensuring the safety of the device operation; in addition, the data transmitted by the photoelectric sensors 6 to the controller can also be used by the device to return the moving frame 2 to the initial reference position before each start-up.
[0050] Preferably, see Figure 1 In one specific embodiment, the electric lifting assembly includes a linear motor 8, which is vertically positioned and connected to the movable frame 2 via a drive end. The linear motor 8 is also signal-connected to the controller of the intelligent sewing cabinet. When adjusting the clarity of sewing footage, the controller can control the linear motor 8 to lift and lower the fixed-focus camera 3 on the movable frame 2, thereby directly lifting and lowering it in the vertical direction.
[0051] Preferably, see Figures 2 to 4 The fixed frame 1 includes linear guide columns 101, fixed flanges 102, and a top plate 103. The two linear guide columns 101 are parallel to each other and extend vertically. Each linear guide column 101 has a fixed flange 102 fixed at both its top and bottom ends. The bottom fixed flange 102 is mounted on the intelligent sewing cabinet, while the top fixed flange 102 is connected to the top plate 103. The movable frame 2 is fitted onto the two linear guide columns 101. An electric lifting assembly is fixed to the top plate 103 and drives the movable frame 2 to move along the linear guide columns 101 via a drive end. The linear guide columns 101 provide guidance for the movable frame 2, enabling the fixed-focus camera 3 on the movable frame 2 to stably rise and fall vertically under the drive of the electric lifting assembly.
[0052] Preferably, see Figures 2 to 4 The movable frame 2 is equipped with a linear bearing 9, which is sleeved on two linear guide posts 101 to reduce the friction between the movable frame 2 and the linear guide posts 101, improve the smoothness of the movement of the movable frame 2 and extend the service life of the device.
[0053] Preferably, see Figure 2 In one specific embodiment, the electric lifting assembly includes a rack 10 and a motor 11. The rack 10 is vertically arranged and fixedly connected to the movable frame 2. The motor 11 is fixed on the top plate 103 and meshes with the rack 10 through a gear 12. The motor 11 is connected to the controller of the intelligent sewing cabinet via a signal. When adjusting the clarity of the sewing footage, the controller controls the motor 11 to rotate, which in turn drives the rack 10 to rise and fall vertically via the gear 12. The fixed-focus camera 3 mounted on the movable frame 2 naturally rises and falls synchronously with the rack 10.
[0054] Preferably, see Figure 3 In one specific embodiment, the electric lifting assembly includes a motor 11 and a ball screw 13. The motor 11 is fixed on the top plate 103, and the ball screw 13 is vertically arranged and axially connected to the motor 11. A ball nut 14 is provided on the movable frame 2, and the ball nut 14 is screwed onto the ball screw 13. The motor 11 is signal-connected to the controller of the intelligent sewing cabinet. When adjusting the clarity of the sewing image, the controller controls the motor 11 to drive the ball screw 13 to rotate, and the fixed-focus camera 3 on the movable frame 2 will rise and fall along the ball screw 13 under the action of the ball nut 14.
[0055] Preferably, see Figure 4 and Figure 5 In one specific embodiment, the electric lifting assembly includes a synchronous pulley set 15 and a motor 11. A movable plate 1502, capable of moving vertically along the synchronous belt 1501, is fixed on the synchronous belt 1501 of the synchronous pulley set 15. The movable frame 2 is fixedly connected to the movable plate 1502. The motor 11 is fixed on the top plate 103 and axially connected to the drive wheel 1503 of the synchronous pulley set 15. The motor 11 is signal-connected to the controller of the intelligent sewing cabinet. When adjusting the clarity of the sewing camera image, the controller controls the motor 11 to drive the drive wheel 1503 of the synchronous pulley set 15 to rotate, thereby causing the synchronous belt 1501 to rotate around the drive wheel 1503 and the driven wheel 1504. Since the fixed-focus camera 3 on the movable frame 2 is fixed to the synchronous belt 1501 through the movable plate 1502, the fixed-focus camera 3 can be raised and lowered.
[0056] See Figure 6 and Figure 7 This embodiment also provides an intelligent sewing cabinet, including a main cabinet 4. The main cabinet 4 is equipped with a display screen 16 and a sewing detection area 17. The display screen 16 is connected to the controller signal. The sewing detection area 17 is equipped with the above-mentioned automatic sewing detection clarity adjustment device.
[0057] Because the intelligent stitch cabinet in this embodiment uses the aforementioned automatic stitch image clarity adjustment device, after the stitch 5 is placed in the stitch detection area 17, the fixed-focus camera 3 is activated to continuously collect stitch images. At the same time, the controller controls the electric lifting component to raise and lower according to the clarity of the stitch images captured by the fixed-focus camera 3, thereby adjusting the height of the fixed-focus camera 3. By comparing the clarity of the stitch images collected at different heights, the height of the fixed-focus camera 3 at the optimal clarity of the stitch image is obtained. At this height, the optimal clarity stitch image is captured and saved. Then, the controller determines the effective area of the image, automatically cuts out and retains the effective image, calculates the RGB value of the image color, and compares it with the RGB values of all stitches in the database to obtain the three stitches with the smallest color difference. Finally, the data of these three stitches are transmitted to the display screen 16 for display.
[0058] Furthermore, when the intelligent stitch cabinet in this embodiment is equipped with a self-learning function, it can also determine whether the currently captured stitch image is clear through the controller. If it is clear, the electric lifting component stops rotating, captures and saves the current stitch image, and then the controller determines the effective area of the image, automatically cuts out and retains the effective image, calculates the RGB values of the image color, and compares them with the RGB values of all stitches in the database to obtain the three stitches with the smallest color difference. These three stitch data are then transmitted to the display screen 16 for display. If it is not clear, it can further determine whether the fixed-focus camera 3 should be raised or lowered and execute the action to obtain a clear stitch image. Obviously, after being equipped with the self-learning function, the intelligent stitch cabinet in this embodiment can more efficiently complete color matching and recommend similar stitches.
[0059] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
