Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to an intelligent batching device for automobile seat panels and an operating method thereof. Background Art

[0002] Car seats come in a variety of styles, made from fabrics like fabric, artificial leather, carpet, and cowhide. Due to the unique characteristics of cowhide, custom-made pieces are often die-cut. Each piece is hand-marked and sent to a layout machine, which automatically cuts it. The finished pieces are unlabeled and must be manually sorted before being loaded onto on-site carts. Because the pull-through production model relies on customer orders placed daily, a line change is required after every 20-40 units of each model are produced. This differs from the batch production model of the apparel industry. Due to the varying sewing processes, the front-end process often assembles the pieces in advance, leaving most of the replenishment pieces to be collected manually. This can easily lead to mistakes during pattern changes, lost pieces, and significant labor investment in patching and replenishment. This also results in high production costs and low yield rates.

[0045] In this embodiment, the lifting mechanism includes an AGV trolley 320, and a vertical frame 330 is fixed on the upper side of the AGV trolley. A connecting block 331 is provided on the vertical frame and is vertically slidably connected thereto. A ball screw 332 driven to rotate by a servo motor 338 is vertically installed in the vertical frame. The servo motor is fixed at the upper end of the vertical frame. The servo motor is connected to the ball screw through a coupling 337. The ball screw is rotatably connected to the bearing seats at the upper and lower ends of the vertical frame. A slide 333 fixedly connected to the connecting block is screwed on the ball screw. In addition to transmitting motion torque, the coupling can also compensate for the offset between the two axes due to inaccurate manufacturing and installation, deformation during operation or thermal expansion, so as to achieve stable motion transmission.

[0046] In this embodiment, the conveying platform is laterally fixed on the connecting block, and a mechanical valve 334 for resetting the origin of the conveying platform is also installed on the upper part of the vertical frame. The mechanical valve is used to reset the origin of the connecting block and the conveying platform. Resetting the origin through the mechanical valve can more accurately transmit the reset information to the servo motor.

[0047] In this embodiment, guide rails 336 are respectively installed on both sides of the vertical frame. Two sliders 335 are respectively provided on the guide rails 336. Both sides of the connecting block are fixedly connected to the sliders for the connecting block to slide smoothly up and down.

[0048] In this embodiment, the AGV includes a horizontal frame 321. Drive wheels 323 driven by a drive motor 322 are located on either side of the frame's center. Auxiliary wheels 324 are located on either side of the frame's front and rear. A control box 325 is located within the frame, along with transverse tracks 326 that coordinate with the auxiliary and driving wheels. Lateral movement is controlled by the control box, and the auxiliary and driving wheels are mounted within the transverse tracks to enhance lateral stability.

[0049] In this embodiment, the cutting trolley is constructed from a stacked, lean tube frame, comprising a support frame 210 with four sets of movable wheels 201 at its lower portion. Three layers of track frames 220 are arranged from bottom to top on the support frame, each equipped with a plurality of pulley sets 221. The track frames are tilted downward near the lifting mechanism. A retaining frame 230 is hingedly attached to the upper side of each layer of the track frames, used to block and limit the cutting pieces. When the vertical top block of the conveyor platform is raised, the retaining frame can be actuated upward, releasing the restraint on the cutting piece, allowing the cutting piece to be freely transported to the conveyor platform by the pulley sets on the track frames for storage.

[0050] In this embodiment, the conveyor platform is equipped with an array of grooves 311, within which are mounted omnidirectional wheels 312 driven by motors 314. The omnidirectional wheels' hub rims are equipped with multiple driven rollers 313 positioned at a 45° angle to the wheel's axle axis. The motors are connected to the equipment for conveniently planning the transport path of items. A vertical top block 315 is fixed to the side of the conveyor platform near the cutting trolley, which is used to lift the limit frame during transport.

[0051] In this embodiment, the lower conveyor mechanism comprises multiple sets of omnidirectional wheels arranged in a transverse sequence. The wheel hubs and rims of these wheels are equipped with multiple driven rollers positioned at a 45° angle to the wheel axles. The lower conveyor mechanism receives the cut pieces from the conveyor table and moves them to the designated sewing surface. The upper conveyor mechanism comprises a transverse conveyor belt with push blocks 111 spaced along its length. These conveyor belts transport semi-finished products from each sewing station to the designated next process for further processing, reducing the time required to transport finished products.

[0052] In this embodiment, the omnidirectional wheel may also be a Macomb wheel.

[0053] In this embodiment, several first visual camera mechanisms 112, 113, 114, 115, 116, 117, 118, and 119 are positioned horizontally above the upper conveyor mechanism to capture information about semi-finished pieces. These visual cameras capture information about the semi-finished pieces, which is then fed back to the conveyor belt and delivered to the designated next process according to the settings. Second visual camera mechanisms 341 and 342 are also positioned above the upper conveyor mechanism, near the location of the cutting trolley, to capture information about the placement of the pieces on the conveyor table. This configuration activates the motor within the conveyor module, which is then driven by the omnidirectional wheels connected to the motor. The motor is then in communication with the device, allowing for convenient planning of the item's transport path to the lower conveyor mechanism.

[0054] In this embodiment, the visual photography mechanism adopts Hikvision camera CA060, the lens adopts Fujitsu T1S1210FBA with an effective focal length of 12.8mm, and the operating environment temperature is -18℃~80℃.

[0055] In this embodiment, in order to improve sewing efficiency and reduce the time of changing presser feet, the sewing machine is connected to a variety of presser feet via a pressure clamp converter 410. The pressure clamp converter includes a link fixing block 411 for connecting to the sewing machine presser foot rod 420. The upwardly curved portion of the link fixing block is rotatably connected to a cam turntable 412 via a bolt 415. The cam turntable is provided with positioning concave points 413 spaced apart along the circumferential direction. A snake piece 414 is also fixed to the link fixing block. The snake piece is provided with limiting protrusions that cooperate with the positioning concave points. The presser foot is fixed to the lower side of the cam turntable along the circumferential direction. During the sewing process, the presser foot can be switched according to the shape requirements of different pieces by rotating the presser foot, saving time and effort.

[0056] In this embodiment, the presser feet are respectively a zipper presser foot 401, a conventional presser foot 402, and a tube presser foot 403, which can be quickly switched according to different processes; a presser foot positioning frame 430 is installed on the sewing machine.
