DETAILED DESCRIPTION

[0020] In order to make the purpose, technical scheme and advantage of the utility model more clearly, the technical scheme in the utility model will be clearly and completely described below in combination with the drawing in the utility model.

[0021] Embodiment one, as Figs. 1-3 Shown, an automatic feeding mechanism for intelligent sewing workstation, including tray positioning plate 1, the upper surface of tray positioning plate 1 is provided with model positioning plate 2, model positioning plate 2 top is equipped with first placement mesa and second placement mesa respectively;

[0022] The edge position of first placement mesa is equipped with a plurality of first guide columns 31, and the first guide columns 31 are all vertically fixedly installed on the model positioning plate 2, and two first brushes 32 are fixedly installed on the model positioning plate 2, specifically, two supporting plates are vertically fixedly installed on the model positioning plate 2, the two supporting plates are located on the symmetrical two sides of the first placement mesa respectively, and the first brush 32 is fixedly installed on the side surface of the supporting plate;And the bristles of the two first brushes 32 all face the first placement mesa;Second placement mesa is equipped with positioning block 41, and the lower surface of positioning block 41 is fixedly connected with a plurality of springs 42, and the lower end of the spring 42 is fixedly connected on the model positioning plate 2;A plurality of second guide columns 43 and two second brushes 44 are fixedly installed at the edge position of positioning block 41, specifically, a plurality of guide position holes are vertically provided at the edge position of positioning block 41, the second guide column 43 is respectively fixedly inserted in the corresponding guide position hole, and the two side surfaces of positioning block 41 are each fixedly installed with L-shaped supporting plate, and the second brush 44 is fixedly installed on the side surface of L-shaped supporting plate, and the bristles of the second brush 44 all face the upper surface of positioning block 41.

[0023] Working principle:

[0024] When using it, first select the corresponding model positioning plate 2 for the fabric product A and fabric product B that need to be sewn, then place the model positioning plate 2 on the tray positioning plate 1, and ensure that the tray positioning plate 1 and the model positioning plate 2 are precisely aligned.

[0025] Then, fabric product A and fabric product B are stacked on the upper surface of the first placement platform and the upper surface of the positioning block 41, respectively, and are precisely positioned by the positioning action of the first guide post 31 and the second guide post 43.

[0026] During the sewing process, the robotic suction cup will sequentially pick up fabric product A and fabric product B. When picking up the top layers of fabric product A and fabric product B separately, the first brush 32 and the second brush 44 can be used to brush and comb the fabric products A and B respectively. Thus, when the robotic suction cup picks up multiple layers of fabric products at once, the first brush 32 and the second brush 44 can separate the multiple layers of fabric products, ensuring that each layer of fabric product A and B can be picked up independently and avoiding adhesion. This effectively prevents the robotic suction cup from picking up too many fabric products A and B during the picking process.

[0027] In this embodiment, a spring 42 is installed below the positioning block 41 to provide elastic support for the positioning block 41, thereby effectively reducing the impact force when the robotic suction cup picks up the fabric product and extending the service life of the equipment. At the same time, the elastic adjustment function of the spring 42 can automatically adjust the support force according to the fabric thickness, further optimizing the suction process, ensuring that the fabric product is subjected to uniform force during suction, and improving sewing accuracy and efficiency.

[0028] In Example 2, as a further preferred embodiment of Example 1, a positioning pin 11 is fixedly installed on the upper surface of the tray positioning plate 1, and a positioning hole 21 is opened on the surface of the model positioning plate 2. The positioning pin 11 cooperates with the positioning hole 21. Therefore, when the model positioning plate 2 is placed on the tray positioning plate 1, the precise positioning of the model positioning plate 2 and the tray positioning plate 1 can be achieved through the mutual engagement of the positioning pin 11 and the positioning hole 21. This effectively ensures a stable connection between the model positioning plate 2 and the tray positioning plate 1, preventing displacement during operation, thereby further improving the positioning accuracy of fabric product A and fabric product B, and ensuring the stability and accuracy of sewing operations.

[0029] In this embodiment, the positioning pin 11 may be provided with two positioning pin structures: a circular positioning pin and a diamond-shaped positioning pin. The circular positioning pin and the diamond-shaped positioning pin correspond to different positioning holes 21 to adapt to the positioning requirements of different model positioning plates 2. Through the dual positioning design of the circular positioning pin and the diamond-shaped positioning pin, the stability and reliability of the device are further improved, and the positioning accuracy of the fabric product is optimized.

[0030] In Example 3, as a further preferred embodiment of Example 2, multiple triangular limiting blocks 12 are fixedly installed at the edge of the upper surface of the tray positioning plate 1. The inclined surfaces of the triangular limiting blocks 12 face the model positioning plate 2, and the triangular limiting blocks 12 contact the side surfaces of the model positioning plate 2. Therefore, when the model positioning plate 2 is placed on the tray positioning plate 1, the inclined surfaces of the triangular limiting blocks 12 can guide the model positioning plate 2 to quickly align with the corresponding position on the upper surface of the tray positioning plate 1, effectively reducing manual adjustment time. Subsequently, the positioning pins 11 and positioning holes 21 are precisely engaged to ensure that the model positioning plate 2 is stable and does not move. Furthermore, the contact between the triangular limiting blocks 12 and the side surfaces of the model positioning plate 2 further enhances the stability of the model positioning plate 2, effectively preventing slight displacement caused by external forces, ensuring that fabric products A and B always maintain precise alignment during the sewing process, and improving the overall sewing quality.

[0031] In Example 4, as a further preferred embodiment of Example 1, a locking support rod 13 is vertically fixedly installed at the edge of the upper surface of the pallet positioning plate 1. A locking block 14 is rotatably connected to the outer surface of the locking support rod 13. The locking block 14 has a semi-circular structure. A locking groove is provided at the edge of the upper surface of the model positioning plate 2. The locking block 14 and the locking groove are movably engaged to realize the fixing and unlocking of the model positioning plate 2.

[0032] Therefore, after placing the model positioning plate 2 on the pallet positioning plate 1 and ensuring precise alignment between them, the locking block 14 can be rotated to press its semi-circular surface into the locking groove at the edge of the upper surface of the model positioning plate 2, thus firmly locking the model positioning plate 2 and preventing any displacement during operation. When it is necessary to remove the model positioning plate 2, simply rotate the locking block 14 again to disengage its semi-circular surface from the locking groove, and the model positioning plate 2 can be easily removed, ensuring convenient and efficient operation and further enhancing the practicality and flexibility of the device.

[0033] In Example 5, as a further preferred embodiment of Example 1, a pallet identification sensor 15 is fixedly installed on the lower surface of the pallet positioning plate 1, and an identification area is provided on the lower surface of the model positioning plate 2. The sensing end of the pallet identification sensor 15 passes through the pallet positioning plate 1 and corresponds to the identification area on the lower surface of the model positioning plate 2. The pallet identification sensor 15 can be an infrared sensor. In this embodiment, the signal output end of the pallet identification sensor 15 can be connected to the signal input end of the central control system, thereby enabling accurate identification of the model positioning plate 2 through the pallet identification sensor 15 and real-time transmission of the information of the model positioning plate 2 to the central control system for identification and calibration of the corresponding model positioning plate 2 for different fabric products.

[0034] In Example 6, as a further preferred embodiment of Example 1, a first identification sensor 16 and a second identification sensor 17 are fixedly installed inside the pallet positioning plate 1. The first and second placement surfaces are respectively provided with a first identification through-hole and a second identification through-hole. A third identification through-hole is provided on the surface of the positioning block 41, with the third identification through-hole directly opposite the second identification through-hole. The sensing end of the first identification sensor 16 passes through the first identification through-hole and corresponds to the material above the first placement surface. The sensing end of the second identification sensor 17 passes through both the second and third identification through-holes and corresponds to the material above the positioning block 41. Specifically, the first identification sensor 16 and the second identification sensor 17 can be infrared sensors. In this embodiment, the signal output terminals of the first identification sensor 16 and the second identification sensor 17 can be connected to the signal input terminal of the central control system. The first identification sensor 16 and the second identification sensor 17 can accurately identify the type of fabric on the first placement surface and the positioning block 41, respectively, and transmit data to the central control system in real time, ensuring accurate matching between the fabric and the model positioning plate 2, further improving production efficiency and product quality.
