Description

Technical Field

[0001] This invention relates to the field of garment production equipment technology, and in particular to a 3D curved surface dispensing machine for garment production. Background Technology

[0002] Garment dispensing machines are automated specialized equipment used in the garment manufacturing industry to replace traditional manual gluing and sewing, achieving precise fabric bonding, seamless splicing, three-dimensional decoration, and waterproof sealing. They are core equipment driving the upgrading of garment production towards higher efficiency, higher quality, and greater flexibility. The core of a garment dispensing machine consists of an adhesive supply system, a precision dispensing valve, a servo motion platform, a vision positioning system, and an intelligent control system. It is compatible with various adhesives such as hot melt adhesives, silicone, AB glue, and water-based adhesives, and is widely used in seamless underwear, sportswear, swimwear, yoga wear, and outdoor clothing for cup bonding, elastic seams, waterproof strip sealing, silicone label / 3D pattern production, and rhinestone and glitter decoration.

[0003] Most existing garment dispensing equipment adopts a two-dimensional planar dispensing mode. Even some equipment with three-dimensional dispensing capabilities generally rely on a three-axis linear linkage architecture (X / Y / Z) to achieve three-dimensional point-to-point operations. However, in garment processing, some workpieces require dispensing on curved surfaces. When dealing with such curved surface dispensing requirements, this type of three-axis linkage architecture requires each target dispensing point to have three axes simultaneously perform displacement adjustment actions. The acceleration response is significantly limited by the constraints of multi-axis collaborative control, which directly leads to a significant increase in the dispensing cycle time of a single product, ultimately severely restricting the dispensing processing efficiency of garment products with curved surface structures. Summary of the Invention

[0004] Objective: In order to overcome the shortcomings of the existing technology, the present invention provides a 3D curved surface dispensing machine for garment production, which is suitable for the curved surface processing of fabrics and has a wide range of applications.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows:

[0006] This invention provides a 3D curved surface dispensing machine for garment production, including a machine body and a three-axis module installed on the upper surface of the machine body, and further including: a material rack, a curved surface moving device, a dispensing assembly and a controller; The material rack is fixedly installed on the upper surface of the machine body; The curved surface moving device is mounted on the Y-axis mechanism of the three-axis module and includes an arc-shaped guide rail, a connecting frame, a bracket, and a motor. The arc-shaped guide rail is mounted on the side of the Y-axis mechanism closest to the material rack, and the connecting frame is slidably connected to the inner wall of the outer arc surface of the arc-shaped guide rail. The bracket has a Z-shaped structure, with the first side of the bracket fixedly connected to the upper surface of the connecting frame. The motor is fixedly connected to the second side of the bracket and slidably connected to the inner arc surface of the arc-shaped guide rail through the bracket. The dispensing assembly includes an assembler, a vision camera, and a dispensing head; the assembler is located at the third end of the bracket and is used to support the vision camera and the dispensing head. The controller is mounted on the machine body and is used to control the working status of the motor and to control the dispensing head to perform dispensing operations.

[0007] The three-axis module is bolted to the machine body via the Z-axis mechanism, and the three-axis module is electrically connected to the machine body.

[0008] This 3D curved surface dispensing machine for garment production uses a curved surface moving device to drive the dispensing head in the dispensing assembly to make arc movements, eliminating the need for overall control of the three-axis module, making it convenient and efficient to use.

[0009] In some embodiments, the motor is a high-precision servo motor with a self-locking brake function.

[0010] A high-precision servo motor with a self-locking brake function is used to ensure that the motor can be locked at a fixed point during use.

[0011] In some embodiments, the two ends of the arc-shaped guide rail are also connected to a fixing frame, which is fixedly connected to the Y-axis mechanism of the three-axis module.

[0012] In some embodiments, the side of the connecting frame near the arc-shaped guide rail has an arc-shaped structure adapted to the arc-shaped guide rail.

[0013] The curved structure that adapts to the curved guide rail prevents the connecting frame from getting stuck during movement, ensuring the smooth movement of the connecting frame within the curved guide rail.

[0014] In some embodiments, a gear is fixedly connected to the drive shaft of the motor; a groove is provided on the inner arc surface of the arc-shaped guide rail, and a rack adapted to the gear is fixedly connected in the groove; the rack is arc-shaped.

[0015] The gear meshes with the rack, allowing the gear, driven by the motor, to move in conjunction with the rack support, connecting frame, assembler, and dispensing head. The rack is arranged in an arc shape.

[0016] In some embodiments, the assembler includes a configuration frame and multiple columns, one end of which is fixedly connected to the configuration frame and the other end of which is fixedly connected to a second side of the support; the dispensing head is mounted on the inner wall of the configuration frame; the vision camera is mounted on the dispensing head; and the vision camera is electrically connected to the machine body.

[0017] In some embodiments, the surface of the configuration rack is further provided with an adjustment device, the adjustment device including: a mounting plate, a linkage shaft and a knob; The assembly plate is slidably connected to the inner wall of the configuration rack; The linkage shaft is rotatably connected to the inner wall of the mounting frame, and the surfaces of the linkage shaft and the mounting plate are provided with intermeshing teeth. The knob is installed at one end of the linkage shaft.

[0018] The linkage shaft and the assembly plate are engaged by a convex tooth, ensuring that the linkage shaft can drive the assembly plate to move in the vertical direction when rotating, so as to adjust the position of the dispensing head and thus change the radius of the dispensing head on the curved surface moving device.

[0019] In some embodiments, the adjustment device further includes a locking bracket; The linkage shaft has a circular hole at the end away from the knob, and the inner wall of the circular hole is fitted with a retaining pin. The locking frame is rotatably connected to the surface of the locking pin, and the locking frame is movably abutting against the surface of the mounting frame; The rotation axis of the locking frame is eccentrically set.

[0020] The rotation axis of the locking frame is eccentrically set so that the locking frame can form an eccentric pressing or eccentric releasing action during the rotation of the locking frame around the eccentric axis.

[0021] In some embodiments, a damping pad is fixedly connected to the side of the knob near the linkage shaft, and the damping pad movably abuts against the surface of the mounting bracket; A return spring is fixedly connected to the edge of the linkage shaft away from the knob, and the return spring is in movable contact with the inner wall of the mounting bracket.

[0022] Damping pads are used to increase the coefficient of friction between the knob and the mounting bracket in the locked state; the reset spring is provided to apply preload to the linkage shaft in the locked state to improve the stability of the linkage shaft in the locked state.

[0023] In some embodiments, the mounting plate has grooves on both sides, and the inner wall of the mounting frame has protruding keys that are adapted to the grooves.

[0024] The combination of the slide and the key can constrain the movement direction of the assembly plate, ensuring that the assembly plate can only move in the vertical direction.

[0025] In some embodiments, a protective cover is slidably connected to the inner wall of the inner arc surface of the arc-shaped guide rail, and the protective cover is sleeved on the surface of the gear. The protective cover is fixedly connected to telescopic covers at both ends, and the telescopic covers are slidably connected to the inner wall of the inner arc surface of the arc-shaped guide rail. The end of the telescopic cover furthest from the protective cover is fixedly connected to the fixed frame.

[0026] The protective cover is fitted onto the surface of the gear to protect the meshing area of ​​the gear and rack. The telescopic covers on both sides of the protective cover are used to protect the exposed parts of the rack. The telescopic cover is slidably connected to the inner wall of the inner arc surface of the arc-shaped guide rail, and the end of the telescopic cover away from the protective cover is fixedly connected to the fixed frame, so that the telescopic cover can extend and retract synchronously with the movement of the protective cover, fully covering the exposed area of ​​the rack, and will not interfere with the movement trajectory of the protective cover.

[0027] Beneficial effects:

[0028] 1. The 3D curved surface dispensing machine for garment production provided by this invention is equipped with a curved surface movement device on a three-axis module. This allows the dispensing machine to drive the dispensing head to make arc-shaped movements based on the three-axis module, making it suitable for processing curved surfaces of fabrics. This increases the smoothness of the dispensing machine when performing curved surface dispensing operations and avoids the problem that in a three-axis linkage architecture, each target dispensing point requires three axes to perform displacement adjustment actions simultaneously when dealing with such curved surface dispensing needs. The acceleration response is significantly limited by the constraints of multi-axis collaborative control, which directly leads to a significant increase in the dispensing cycle time of a single product and ultimately seriously restricts the dispensing processing efficiency of garment products with curved surface structures.

[0029] 2. Because an adjustment device for adjusting the radius of the dispensing head is set between the curved surface moving device and the dispensing head, the moving radius of the dispensing head can be adapted to fabrics with different curvatures when moving on a curved surface, thus further increasing the applicability of the equipment.

[0040] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit the present invention or its application or use.

[0041] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may include different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.

[0042] Example 1:

[0043] This embodiment provides a 3D curved surface dispensing machine for garment production, such as... Figure 1 As shown, the system includes a machine body 1, a controller 2, a three-axis module 3, a material rack 4, a curved surface moving device 5, and a dispensing assembly. The controller 2 is mounted on the machine body and is electrically connected to the machine body 1. The three-axis module 3 is mounted on the upper surface of the machine body 1 and is bolted to the machine body 1 via a Z-axis mechanism. The material rack 4 is fixedly mounted on the upper surface of the machine body 1 with bolts.

[0044] like Figure 3 , Figure 5 and Figure 6 As shown, the curved surface moving device 5 is mounted on the Y-axis mechanism of the three-axis module 3, and includes an arc-shaped guide rail 52, a connecting frame 53, a bracket 54, and a motor 55. The arc-shaped guide rail 52 is mounted on the side of the Y-axis mechanism near the material rack 4, and the connecting frame 53 is slidably connected to the inner wall of the outer arc surface of the arc-shaped guide rail 52. The bracket 54 has a Z-shaped structure, and the first side 541 of the bracket 54 is fixedly connected to the upper surface of the connecting frame 53 by bolts. The motor 55 is fixedly connected to the second side 542 of the bracket 54 by bolts, and is slidably connected to the inner arc surface of the arc-shaped guide rail 52 through the bracket 54. The side of the connecting frame 53 near the arc-shaped guide rail 52 has an arc-shaped structure adapted to the arc-shaped guide rail 52.

[0045] A fixed frame 51 is fixedly connected to the Y-axis mechanism of the three-axis module 3. The fixed frame 51 is bolted to the lower surface of the arc-shaped guide rail 52. The fixed frame 51 can install the arc-shaped guide rail 52 on the three-axis module 3, so that the three-axis module 3 can drive the arc-shaped guide rail 52 to move.

[0046] Motor 55 is a high-precision servo motor with a self-locking brake function to ensure that motor 55 can achieve fixed-point locking during use. Figure 4 As shown, a gear 56 is bolted to the drive shaft of the motor 55, and a groove is provided on the inner arc surface of the arc-shaped guide rail 52. A rack 57 adapted to the gear 56 is fixedly connected in the groove.

[0047] like Figure 2 As shown, the dispensing assembly includes an assembler 58, a vision camera 8, and a dispensing head 7; the assembler 58 is located at the end of the third side 543 of the bracket 54 and is used to support the vision camera 8 and the dispensing head 7. Figure 3 and Figure 5 As shown, the assembler 58 includes a configuration frame 582 and multiple columns 581; one end of the column 581 is welded to the configuration frame 582, and the other end is fixedly connected to the second side 542 of the bracket 54 by bolts; the inner wall of the configuration frame 582 is provided with a dispensing head 7, and a vision camera 8 is fixedly connected to the surface of the dispensing head 7. The vision camera 8 is electrically connected to the body 1. The dispensing head 7 and the vision camera 8 are mature existing technologies, and their control and working principles will not be described in detail here.

[0048] like Figure 2 and Figure 3 As shown, a protective cover 59 is slidably connected to the inner wall of the inner arc surface of the arc-shaped guide rail 52. The protective cover 59 is fitted onto the surface of the gear 56 to protect the meshing area of ​​the gear 56 and the rack 57. Telescopic covers 510 are fixedly connected to both ends of the protective cover 59 to protect the exposed parts of the rack 57. The telescopic covers 510 are slidably connected to the inner wall of the inner arc surface of the arc-shaped guide rail 52. The side of the telescopic cover 510 away from the protective cover 59 is fixedly connected to the surface of the fixing frame 51, so that the telescopic cover 510 can extend and retract synchronously with the movement of the protective cover 59, fully covering the exposed area of ​​the rack 57 without interfering with the movement trajectory of the protective cover 59.

[0049] like Figure 2 and Figure 7 As shown, the surface of the mounting frame 582 is provided with an adjustment device 6, which includes a mounting plate 61, a linkage shaft 62, and a knob 63. The mounting plate 61 is slidably connected to the inner wall of the mounting frame 582, and the inner wall of the mounting frame 582 is rotatably connected to the linkage shaft 62. Both the surface of the linkage shaft 62 and the surface of the mounting plate 61 are provided with protruding teeth. The linkage shaft 62 and the mounting plate 61 are engaged by the protruding teeth to ensure that when the linkage shaft 62 rotates, it can drive the mounting plate 61 to move in the vertical direction to adjust the position of the dispensing head 7, thereby changing the radius of the dispensing head 7 on the curved surface moving device 5. The knob 63 is installed at one end of the linkage shaft 62. The surface of the linkage shaft 62 has a circular hole, and the inner wall of the circular hole is interference-fitted with a retaining pin 66. The surface of the retaining pin 66 is rotatably connected to a locking frame 67, which is in movable contact with the surface of the mounting frame 582.

[0050] like Figure 5 and Figure 7 As shown, the mounting plate 61 has sliding grooves on both sides, and the inner wall of the mounting bracket 582 has a protruding key that matches the sliding groove. The cooperation between the sliding groove and the protruding key can constrain the movement direction of the mounting plate 61, ensuring that the mounting plate 61 can only move in the vertical direction. The rotation axis of the locking bracket 67 is eccentrically set so that the locking bracket 67 can form an eccentric pressing or eccentric releasing action during the rotation of the locking bracket 67 around the eccentric axis.

[0051] Example 2:

[0052] This embodiment, based on Embodiment 1, provides a structurally optimized 3D curved surface dispensing machine for garment production. The difference from Embodiment 1 is that, as shown in... Figure 7 and Figure 8As shown, a damping pad 64 is fixedly connected to the side of the knob 63 near the linkage shaft 62. The damping pad 64 movably abuts against the surface of the mounting bracket 582. The damping pad 64 is used to increase the coefficient of friction between the knob 63 and the mounting bracket 582 in the locked state. A return spring 65 is fixedly connected to the edge of the linkage shaft 62 away from the knob 63. The return spring 65 movably abuts against the inner wall of the mounting bracket 582. Through the return spring 65, a preload force can be applied to the linkage shaft 62 in the locked state to improve the stability of the linkage shaft 62 in the locked state.

[0053] In use, the fabric is placed on the material rack 4, and the controller 2 controls the three-axis module 3 and the dispensing head 7 to work. The three-axis module 3 moves the dispensing head 7. When the dispensing head 7 moves above the fabric, the vision camera 8 determines that the dispensing head 7 has moved into place through visual detection, and cooperates with the controller 2 to control the dispensing head 7 to perform the dispensing operation.

[0054] During curved surface processing, the equipment continues the actions described above. When the dispensing head 7 performs dispensing operations, the motor 55 operates under the control of the controller 2 and drives the gear 56 to rotate. The gear 56 meshes with the rack 57 in the working state, thereby moving the motor 55, which is fixed by the bracket 54 and the connecting frame 53. Guided by the connecting frame 53 and the arc-shaped guide rail 52, the motor 55 performs arc-shaped displacement. The connecting frame 53, in conjunction with the assembler 58, drives the dispensing head 7 to move, allowing the dispensing head 7 to move around the curved surface of the fabric during dispensing. This is because the three-axis module 3 is equipped with a curved surface for movement. The surface movement device 5 enables the dispensing machine to drive the dispensing head 7 in an arc-shaped motion based on the three-axis module 3, making it suitable for processing curved surfaces of fabrics. This increases the smoothness of the dispensing machine when performing curved surface dispensing operations and avoids the problem that the three-axis linkage architecture requires three axes to perform displacement adjustment actions simultaneously for each target dispensing point when dealing with such curved surface dispensing needs. The acceleration response is significantly limited by the constraints of multi-axis collaborative control, which directly leads to a significant increase in the dispensing cycle time of a single product and ultimately seriously restricts the dispensing processing efficiency of clothing products with curved surface structures.

[0055] Additionally, when the curvature or radius of the fabric surface changes during processing, the material rack 4 is replaced to fit the size of the fabric surface. After replacing the material rack 4, the locking frame 67 is moved, causing it to rotate around the locking pin 66, thus performing an eccentric release action. After the locking frame 67 is unlocked, the return spring 65 loses the pressure applied by the linkage shaft 62 and pushes the linkage shaft 62 to reset. After the linkage shaft 62 resets, the damping pad 64 disengages from the mounting frame 582. At this time, the linkage shaft 62 is rotated by the knob 63, engaging with the assembly plate 61. The assembly plate 61 moves the dispensing head 7 and adjusts the distance between the dispensing head 7 and the fabric, completing the adjustment. After the operation, the locking frame 67 is moved to make it eccentrically press against the mounting frame 582. At this time, the locking frame 67 pulls the linkage shaft 62, and the linkage shaft 62 pulls the knob 63 and the damping pad 64. The damping pad 64 abuts against the mounting frame 582. Then, with the cooperation of the locking frame 67, the knob 63 and the damping pad 64, the linkage shaft 62 is locked, completing the entire adjustment process. Since the adjustment device 6 for adjusting the radius of the dispensing head 7 is set between the curved surface moving device 5 and the dispensing head 7, the moving radius of the dispensing head 7 can be applied to fabrics with different curvatures when moving on a curved surface, further increasing the applicability of the equipment.
