Description

Technical Field

[0001] This utility model relates to the field of hat piece sewing technology, specifically a correction mechanism for a hat piece sewing device. Background Technology

[0002] A hat is made by stitching together multiple pieces of fabric, and each piece requires two pieces of fabric placed on opposite sides to be sewn together. Currently, the sewing of hat pieces is mostly done manually. Workers take two pieces of fabric from a basket, stack them together, and then sew them together using a sewing machine to complete the hat piece production.

[0003] With rising labor costs leading to increased production costs, and due to variations in worker skills and proficiency, inconsistencies in hat panel production can easily arise, making it difficult to control hat quality. Manual sewing is costly, physically demanding, inefficient, and results in inconsistent product quality; therefore, automated hat panel sewing equipment is needed. To ensure hat panel quality, the two pieces of material must be aligned before sewing, necessitating a material alignment process. Utility Model Content

[0004] The purpose of this utility model is to overcome the above-mentioned deficiencies and disclose to the public a correction mechanism for a hat piece sewing device with a reasonable structure. It detects whether the hat piece material is placed in the set position by image comparison, so that the two hat piece materials can be accurately aligned, which helps to ensure the quality of the sewn hat piece product.

[0005] The technical solution of this utility model is implemented as follows: A correction mechanism for a cap piece sewing device includes a frame, a correction platform on the frame, a positioning groove on the correction platform, an adjustment mechanism next to the correction platform, an adjustment suction head on the adjustment mechanism that can move in space and rotate horizontally, a camera above the correction platform, and a conveying mechanism next to the correction platform for conveying cap piece raw materials from a feeding mechanism to the correction platform.

[0006] Further optimization measures for this technical solution are as follows: As an improvement, the frame is equipped with a Y-axis slide rail, on which a Y-axis slider slides. An X-axis slide rail is fixed to the Y-axis slider, on which an X-axis slider slides. A rotatable mounting base is provided on the X-axis slider, and a first vertical cylinder is mounted on the mounting base. The adjusting suction head is fixed to the first vertical cylinder. The cooperation between the Y-axis slider and the Y-axis slide rail enables movement in the Y-axis direction, the cooperation between the X-axis slider and the X-axis slide rail enables movement in the X-axis direction, and the first vertical cylinder enables movement in the Z-axis direction, thereby realizing the movement of the adjusting suction head in space.

[0007] As an improvement, the X-axis slider is equipped with a rotation drive device, which is connected to a transmission shaft via a synchronous belt. The mounting base is fixed to the transmission shaft. The rotation drive device drives the transmission shaft to rotate, which in turn drives the mounting base to rotate, thereby adjusting the horizontal rotation of the adsorption head and thus adjusting the angle of the raw material placement on the cap.

[0008] As an improvement, a Y-axis cable chain is connected to the Y-axis slider, and an X-axis cable chain is connected to the X-axis slider. Moving the corresponding sliders via the cable chains makes the slider movement smoother.

[0009] As an improvement, the frame is provided with a camera bracket that spans the correction platform, and the camera is fixed on the camera bracket.

[0010] As an improvement, the conveying mechanism includes a base, a horizontal slide rail on the base, a slide block on the horizontal slide rail, a second vertical cylinder fixed on the slide block, and a conveying suction head on the second vertical cylinder.

[0011] As an improvement, slide rails are provided on both sides of the horizontal slide rail, and the slides slide in slidable engagement with the slide rails.

[0012] As an improvement, the second vertical cylinder is provided with an adsorption head bracket, and the conveying adsorption heads are fixed in parallel on the adsorption head bracket.

[0013] The advantages of this utility model compared with the prior art are: This utility model discloses a correction mechanism for a cap piece sewing device. The mechanism has a reasonable structure and uses a correction platform with positioning slots on the frame. A camera is positioned above the correction platform to detect whether the cap piece material is accurately placed in the positioning slot using image comparison technology. If the cap piece material deviates from the positioning slot, the adjustment mechanism corrects its position to ensure that the cap piece material is placed in the designated position. This ensures that two cap pieces are accurately aligned during subsequent overlapping and sewing, thereby guaranteeing the quality of the sewn cap piece product. Attached Figure Description

[0016] The present invention will be further described in detail below with reference to the accompanying drawings: The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious modifications will be apparent to those skilled in the art. The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

[0017] Those skilled in the art should understand that in the disclosure of this utility model, the terms "longitudinal", "lateral", "up", "down", "left", "right", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or position based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0018] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0019] like Figures 1 to 5 As shown, a correction mechanism for a cap piece sewing device includes a frame 1, a correction platform 2 on the frame 1, a positioning groove 2a on the correction platform 2, an adjustment mechanism next to the correction platform 2, an adjustment suction head 3 that can move in space and rotate horizontally on the adjustment mechanism, a camera 4 above the correction platform 2, and a conveying mechanism 5 next to the correction platform 2 for conveying cap piece raw materials from the feeding mechanism to the correction platform 2.

[0020] Adjust the connection between the adsorption head 3 and the negative pressure device to use negative pressure to adsorb the raw material on the cap sheet.

[0021] The frame 1 is provided with a Y-axis slide rail 61, on which a Y-axis slider 62 is slidably fitted. An X-axis slide rail 63 is fixed on the Y-axis slider 62, on which an X-axis slider 64 is slidably fitted. A rotatable mounting base 65 is provided on the X-axis slider 64, and a first vertical cylinder 66 is provided on the mounting base 65. The adjusting suction head 3 is fixed on the first vertical cylinder 66.

[0022] The X-axis slider 64 is equipped with a rotation drive device 71, which is connected to a transmission shaft 73 via a synchronous belt 72. The mounting base 65 is fixed to the shaft 73. The rotation drive device 71 is preferably a motor.

[0023] The Y-axis slider 62 is connected to a Y-axis cable chain 81, and the X-axis slider 64 is connected to an X-axis cable chain 82. Moving the corresponding sliders via the cable chains allows for smoother movement of the sliders.

[0024] The length direction of frame 1 is the X-axis (movement from the feeding mechanism to the correction platform 2 is the X-axis direction), the width direction of frame 1 is the Y-axis (i.e., the front side of frame 1 is closer to or further away from it), and the longitudinal direction is the Z-axis. In the adjustment mechanism, movement in the Y-axis direction is achieved through the cooperation of Y-axis slider 62 and Y-axis slide rail 61; movement in the X-axis direction is achieved through the cooperation of X-axis slider 64 and X-axis slide rail 63; and movement in the Z-axis direction is achieved through the first vertical cylinder 66, thereby adjusting the spatial position of the adsorption head 3. Additionally, the rotation of the rotating shaft 73 driven by a motor achieves horizontal rotation of the adsorption head 3. This enables the adsorption head 3 to move in space and rotate horizontally, allowing adjustment of the placement position of the cap material on the correction platform 2.

[0025] The frame 1 is equipped with a camera bracket 41 that spans the correction platform 2, and the camera 4 is fixed to the camera bracket 41. This arrangement facilitates the installation of the camera 4 and the adjustment of its position.

[0026] The conveying mechanism 5 includes a base 51, a horizontal slide rail 52 on the base 51, a slide block 53 on the horizontal slide rail 52, a second vertical cylinder 54 fixed on the slide block 53, and a conveying suction head 55 mounted on the second vertical cylinder 54. In this embodiment, the slide block 53 is driven to move by the cylinder. Through the cooperation of the slide block 53 and the second vertical cylinder 54, the movement of the conveying suction head 55 in space is realized.

[0027] The horizontal slide rail 52 is provided with slide guide rails 56 on both sides, and the slide 53 slides in cooperation with the slide guide rails 56. The slide guide rails 56 make the movement of the slide 53 smoother.

[0028] The second vertical cylinder 54 is equipped with an adsorption head bracket 55a, and the conveying adsorption heads 55 are fixed in parallel on the adsorption head bracket 55a. The adsorption head bracket 55a facilitates the fixation of the adsorption heads 55.

[0029] The conveying adsorption head 55 is also connected to the negative pressure device, using negative pressure to adsorb the raw material from the cap sheet.

[0030] Working principle: When the conveying mechanism 5 transports the cap piece material from the upstream feeding mechanism to the correction platform 2, the cap piece material may fail to be accurately placed in the set position due to various reasons. Therefore, the cap piece sewing device is equipped with the correction platform 2 to perform correction operation on the position of the cap piece material before sewing.

[0031] Specifically, the correction platform 2 is equipped with a positioning groove 2a, which is the designated position for the cap piece material. The camera 4 above the correction platform 2 captures images of the platform. The main control board uses image comparison technology (a mature existing technology) to compare the position of the cap piece material with the position of the positioning groove 2a to determine if the material is placed in the designated position. If the position of the cap piece material deviates, the main control board sends a control signal to the adjustment mechanism to correct its position, ensuring the material is placed correctly. This allows for accurate alignment of the two cap pieces during subsequent overlapping and sewing, thus guaranteeing the quality of the sewn cap product.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
