The feeding device 60 can be slidably arranged on the workbench 11, and is located on one side of the eyelet device 30, the laminating device 40 and the sewing device 50. The feeding device 60 is responsible for transferring the cap piece between each processing link to ensure the smoothness and continuity of the entire sewing process. It should be noted that the feeding device 60 may include a clamping mechanism and a sliding mechanism, which clamps the cap piece through the clamping mechanism, and drives the clamping mechanism to slide back and forth between the eyelet device 30, the laminating device 40 and the sewing device 50 through the sliding mechanism and transfer the cap piece. The positioning device is arranged on the workbench 11, and passes through the feeding device 20, the eyelet device 30, the laminating device 40 and the sewing device 50. The positioning device can use sensors or mechanical control technology, which can accurately locate the position of the cap piece, ensuring that each processing link can perform precise operations on the cap piece.

[0092] Therefore, it can be understood that the cap piece sewing machine according to the embodiment of the present invention has at least the following beneficial effects: the feeding device 20 grabs two cap pieces onto the eyelet device 30, the eyelet device 30 sews the eyelets of the two cap pieces in turn, and the cap pieces are transported by the feeding device 60, and the cap pieces are transferred from the eyelet device 30 to the laminating device 40, and the laminating device 40 laminates the two cap pieces, and then sews them through the sew device 50. The cap piece sewing machine can replace manual work to sew the eyelets of the two cap pieces and sew the two cap pieces at the same time.

[0093] Reference Figure 1 to Figure 2In some embodiments of the present invention, the positioning device includes a first positioning mechanism 71, which is arranged on the feeding device 20. The feeding device 20 also includes: a supporting mechanism 22 and a first sliding mechanism 23. The supporting mechanism 22 can be raised and lowered on the workbench 11. There are two supporting mechanisms 22, which are respectively located below the two grabbing mechanisms 21. The cap piece is placed on the supporting mechanism 22. There are two first positioning mechanisms 71, which are symmetrically arranged between the two first positioning mechanisms 71. The two first positioning mechanisms 71 are respectively located below the two supporting mechanisms 22. The first positioning mechanism 71 is configured to limit the cap piece on the supporting mechanism 22; the first sliding mechanism 23 is arranged on the workbench 11, and the two grabbing mechanisms 21 are arranged on the output end of the first sliding mechanism 23. The first sliding mechanism 23 is configured to drive the grabbing mechanism 21 away from or close to the embroidery eye device 30.

[0094] In addition to the two original liftable gripping mechanisms 21, the feeding device 20 is further provided with two supporting mechanisms 22. The two supporting mechanisms 22 are liftably arranged on the workbench 11 and are respectively located below the two gripping mechanisms 21. When the cap pieces are placed on the sewing machine, they are first placed on the supporting mechanisms 22 to provide support for subsequent gripping and positioning. In order to further ensure the stability of the cap pieces on the supporting mechanisms 22, two first positioning mechanisms 71 are provided, which are symmetrically arranged and respectively located below the two supporting mechanisms 22. The design of the first positioning mechanism 71 enables it to effectively limit the cap pieces on the supporting mechanisms 22 to prevent the cap pieces from moving or shifting during the processing process, thereby ensuring the accuracy and quality of sewing. In addition, the feeding device 20 also includes a first sliding mechanism 23, which is arranged on the workbench 11, and the two gripping mechanisms 21 are installed on the output end of the first sliding mechanism 23. The first sliding mechanism 23 is configured to drive the grasping mechanism 21 to slide on the workbench 11, so that the grasping mechanism 21 can move away from or approach the eyelet device 30. This design not only facilitates the feeding and unloading operation of the cap piece, but also makes the entire sewing process smoother and more efficient. After the grasping mechanism 21 grasps the cap piece, the first sliding mechanism 23 drives the grasping mechanism 21 to accurately transport the cap piece to the eyelet device 30 for sewing, thereby realizing the automated or semi-automated production of the cap piece sewing.

[0095] Further, refer to Figure 2In some embodiments of the present invention, the first positioning mechanism 71 includes a first positioning rod 711 and a plurality of first limiting rods 712. The first positioning rod 711 can be inserted into the support mechanism 22 and inserted into the eye of the cap piece. The plurality of first limiting rods 712 are located on the outer peripheral side of the cap piece. The first positioning mechanism 71 is mainly composed of the first positioning rod 711 and the plurality of first limiting rods 712. The two parts work together to ensure the accurate positioning of the cap piece on the support mechanism 22. The first positioning rod 711 is designed to be inserted into the support mechanism 22 and inserted into the eye of the cap piece. This design uses the eye on the cap piece as a positioning point, so that the first positioning rod 711 can firmly fix the cap piece to prevent it from moving during subsequent processing; in addition, the eye of the cap piece can also be positioned. At the same time, the way the first positioning rod 711 is inserted also ensures the close cooperation between it and the support mechanism 22, and enhances the stability of the entire positioning system. In addition to the first positioning rod 711, the first positioning mechanism 71 also includes a plurality of first limiting rods 712. The first limiting rods 712 are arranged on the outer peripheral side of the cap piece, and their function is to further limit the position of the cap piece to prevent it from lateral deviation. The number and position of the first limiting rods 712 can be adjusted according to the shape and size of the cap piece to ensure the best positioning effect.

[0096] In summary, the first positioning mechanism 71 realizes accurate positioning of the cap piece on the supporting mechanism 22 through the cooperation of the first positioning rod 711 and the first limiting rod 712. This design not only improves the automation of the sewing machine, but also ensures the accuracy and stability of the sewing process, thereby improving the quality and production efficiency of the product.

[0097] Reference Figure 1 as well as Figure 3 In some embodiments of the present invention, the positioning device further includes a second positioning mechanism 72, which is disposed on the eyelet device 30, and the eyelet device 30 includes a first sewing mechanism 31 and a first pressing mechanism 32. The first sewing mechanism 31 is disposed on the workbench 11, and the first sewing mechanism 31 is configured to sew the eyelets on the cap piece; the first pressing mechanism 32 is movably disposed on the workbench 11, and two second positioning mechanisms 72 are disposed, and the two second positioning mechanisms 72 are disposed below the workbench 11, and the second positioning mechanism 72 is configured to position the eyelets of the cap piece, and the first pressing mechanism 32 is configured to press the cap piece against the workbench 11.

[0098] For the cap piece sewing machine, its positioning device further includes a second positioning mechanism 72, which is arranged on the embroidery eye device 30 and works in conjunction with other parts of the embroidery eye device 30 to ensure the accurate positioning of the cap piece during the embroidery eye sewing process. The embroidery eye device 30 includes a first sewing mechanism 31, which is fixedly arranged on the workbench 11 and configured to sew the embroidery eye on the cap piece. When the first sewing mechanism 31 is working, it is necessary to ensure that the position of the cap piece is stable and accurate to ensure the sewing quality of the embroidery eye. In order to achieve this goal, the embroidery eye device 30 is also equipped with a first pressing mechanism 32. The first pressing mechanism 32 is movably arranged on the workbench 11, and can be lowered when necessary and press the cap piece against the workbench 11. At the same time, the first sewing mechanism 31 drives the cap piece relative to the sewing table of the first sewing mechanism 31 and slides along the sewing track of the embroidery eye during the sewing of the embroidery eye, preventing it from moving relative to the position of the first pressing mechanism 32 during the sewing process. In addition, two second positioning mechanisms 72 are also arranged below the embroidery eye device 30. The two second positioning mechanisms 72 are arranged symmetrically, and their main function is to position the eyelets of the cap piece. When the cap piece is placed on the workbench 11, the second positioning mechanism 72 will be accurately aligned with the eyelets of the cap piece. When the second positioning mechanism 72 positions the eyelets of the cap piece, it cooperates with the first pressing mechanism 32 to ensure that the cap piece maintains a stable position during the sewing process.

[0099] Further, refer to Figure 3 In some embodiments of the present invention, the second positioning mechanism 72 includes a second lifting member 721 and a second positioning rod 722. The second positioning rod 722 is arranged on the output end of the second lifting member 721. The second lifting member 721 is configured to drive the second positioning rod 722 to pass through the workbench 11 and be inserted into the eye of the cap piece.

[0100] The second positioning mechanism 72 is mainly composed of a second lifting member 721 and a second positioning rod 722. These two parts work together to achieve accurate positioning of the eyelets of the cap piece. The second lifting member 721 is fixedly arranged below the workbench 11, and it has an output end for driving the second positioning rod 722 to perform lifting and lowering movements. The second positioning rod 722 is firmly mounted on the output end of the second lifting member 721, and moves up and down with the drive of the second lifting member 721. During operation, when the cap piece is placed on the workbench 11 and is ready for eyelet sewing, the second lifting member 721 will drive the second positioning rod 722 to rise. The second positioning rod 722 will penetrate the workbench 11 and be accurately inserted into the eyelets of the cap piece. When the second positioning mechanism 72 realizes the positioning of the eyelet of the cap piece, the first pressing mechanism 32 can simultaneously press the cap piece against the sewing table of the first sewing mechanism 31, and then the second lifting member 721 can drive the second positioning rod 722 to descend below the sewing table to avoid the cap piece, so that the first pressing mechanism 32 can press the cap piece and drive the cap piece to slide on the sewing table. This design not only ensures the stable position of the cap piece during the sewing process, but also ensures the accuracy of the eyelet sewing and the smooth progress of sewing.

[0101] Through the cooperation of the second lifting member 721 and the second positioning rod 722, the second positioning mechanism 72 can quickly locate the eyelet position of the cap piece and provide accurate positioning support for subsequent sewing work. This design not only improves the automation level of the cap piece sewing machine, but also further improves the product quality and production efficiency.

[0102] Reference Figure 1 as well as Figure 4 In some embodiments of the present invention, the positioning device further includes a fixing mechanism 73, which is arranged on the laminating device 40, and the laminating device 40 includes: a second driving mechanism 41 and a flip plate 43. The second driving mechanism 41 is rotatably arranged on the workbench 11 through the first driving mechanism 42, and the second driving mechanism 41 is arranged on the output end of the first driving mechanism 42, and the first driving mechanism 42 is configured to drive the second driving mechanism 41 to rotate; there are two flip plates 43, which are symmetrically arranged between the two flip plates 43, and the two flip plates 43 are respectively arranged horizontally on the output end of the second driving mechanism 41, and the two flip plates 43 are arranged oppositely, and the flip plates 43 are used to support the cap pieces, and the second driving mechanism 41 drives the flip plates 43 to flip relatively, so that the cap pieces can be attached to each other, and there are two fixing mechanisms 73, which are arranged below the flip plates 43, and the fixing mechanisms 73 are configured to fix the cap pieces.

[0103] For the cap piece sewing machine, its positioning device further includes a fixing mechanism 73, which is arranged on the fitting device 40 to ensure that the position of the cap piece is fixed during the fitting process. The fitting device 40 includes a second driving mechanism 41 and a flip plate 43. The second driving mechanism 41 is rotatably arranged on the workbench 11 through the first driving mechanism 42, wherein the first driving mechanism 42 is configured as a power source to drive the second driving mechanism 41 to perform rotational motion. Two flip plates 43 are arranged on the output end of the second driving mechanism 41, and the two flip plates 43 are symmetrically arranged and extend horizontally respectively to support the cap piece. During operation, when two cap pieces are conveyed to the fitting device 40, they are placed on the two flip plates 43 respectively. After receiving the instruction, the second driving mechanism 41 will drive the flip plate 43 to flip relative to each other so that the two cap pieces can fit each other. This design not only realizes the automatic fitting of the cap piece, but also ensures the stability and accuracy during the fitting process. In order to prevent the cap piece from slipping off during the flipping and laminating process, two fixing mechanisms 73 are arranged under the laminating device 40. The two fixing mechanisms 73 are respectively located under the two flip plates 43, and their main function is to fix the position of the cap piece. When the flip plate 43 supports the cap piece and flips and laps it, the fixing mechanism 73 will ensure that the position of the cap piece is accurately aligned, thereby ensuring the quality of the cap piece after laminating. At this time, the second driving mechanism 41 can be driven by the first driving mechanism 42 to flip the flip plate 43 flipped to a horizontal state, thereby flipping the laminating cap piece to a horizontal state, which is convenient for the clamping and transfer of the feeding device 60.

[0104] Furthermore, in some embodiments of the present invention, the fixing mechanism 73 includes a driving member (not shown in the figure) and a fixing member (not shown in the figure), the fixing member is arranged on the output end of the driving member, the driving member is configured to drive the fixing member to pass through the flip plate 43, and the fixing member is configured to be able to contact with the cap piece so that the cap piece is fixed on the flip plate 43.

[0105] The fixing mechanism 73 is composed of a driving member and a fixing member, and these two parts are closely matched to prevent the cap piece from slipping during the bonding process. The driving member is firmly arranged below the bonding device 40, specifically below the flip plate 43. It has an output end for driving the fixing member to perform lifting or approaching movements. The fixing member is firmly mounted on the output end of the driving member, and moves away from or close to the cap piece as the driving member drives. During the bonding process of the cap pieces, when two cap pieces are placed on the flip plate 43 and are ready to be bonded, the driving member will receive an instruction to drive the fixing member to approach the cap piece. The fixing member will pass through the reserved hole on the flip plate 43 and accurately fit the cap piece or be inserted in the cap piece. This design not only ensures the stable position of the cap piece during the bonding process, but also ensures the precise alignment between the cap pieces, thereby improving the quality of the cap piece after bonding. Preferably, the fixing part can be a vacuum suction part, and the driving part drives the fixing part to approach the cap piece so that the fixing part is close to and close to the cap piece, so that the negative pressure generated by vacuum extraction can be used to adsorb the cap piece on the vacuum suction part, thereby achieving fixation and positioning of the cap piece; the fixing part can also be a needle puncture suction cup, and the driving part drives the needle in the fixing part to approach and pierce the cap piece, so that the cap piece can be fixed and positioned on the flip plate 43; it can even be a fixing form such as clamping. In the present embodiment, the specific structure of the fixing mechanism 73 is not specifically limited, and it is sufficient to achieve the fixation and positioning of the cap piece.

[0106] By using the driving member and the fixing member in coordination, the fixing mechanism 73 can ensure the position of the cap piece is fixed and provide accurate positioning support for the subsequent fitting work. This design not only improves the automation level of the cap piece sewing machine, but also further ensures the quality and production efficiency of the product, making the fitting process of the cap piece more stable, accurate and efficient.

[0107] Furthermore, refer to Figure 4In some embodiments of the present invention, the laminating device 40 further includes a second pressing mechanism 44, which is arranged on the frame 10 and located above the flip plate 43. The second pressing mechanism 44 includes a lifting and lowering pressing block 441, which is used to press the cap piece against the flip plate 43. Taking the fixing mechanism 73 as an acupuncture suction cup as an example, its laminating device 40 is further equipped with a second pressing mechanism 44 to ensure the stability and accuracy of the cap piece during the laminating process. The second pressing mechanism 44 is arranged on the frame 10 and located above the flip plate 43. This position design enables the second pressing mechanism 44 to play a key role in the laminating process of the cap piece. The core component of the second pressing mechanism 44 is a lifting and lowering pressing block 441, which can move up and down according to actual needs. Before the cap piece is positioned for the embroidery eye, when two cap pieces are placed on the flip plate 43 and are ready to be laminated, the second pressing mechanism 44 will receive an instruction to drive the pressing block 441 to descend. The pressing block 441 will accurately press against the cap piece and firmly fix it on the flip plate 43; at this time, the driving member of the fixing mechanism 73 drives the fixing member to rise. The fixing member will pass through the reserved hole on the flip plate 43 and be accurately inserted into the cap piece. This design not only ensures the stable position of the cap piece during the bonding process, prevents the cap piece from slipping when the flip plate 43 is flipped, but also ensures the precise alignment between the cap pieces. This design not only prevents the cap piece from moving or deflecting during the bonding process, but also ensures the smooth progress of the bonding process.

[0108] Reference Figure 1 as well as Figure 5 In some embodiments of the present invention, the positioning device further includes a third positioning mechanism 74, which is disposed on the seaming device 50, and the seaming device 50 includes: a second sewing mechanism 51 and a third pressing mechanism 52.

[0109] For the cap piece sewing machine, its positioning device is further provided with a third positioning mechanism 74, which is arranged on the sewing device 50 to ensure the accurate alignment and stable fixation of the cap piece during the sewing process. The sewing device 50 includes a second sewing mechanism 51 and a third pressing mechanism 52. The second sewing mechanism 51 is fixedly arranged on the workbench 11, and it is responsible for sewing the two cap pieces that have been bonded. In order to ensure the accuracy and aesthetics of the sewing, the edges of the cap pieces must be aligned with each other. In order to achieve this goal, a third positioning mechanism 74 is arranged below the sewing device 50. The third positioning mechanism 74 is located below the workbench 11, and its main function is to ensure that the edges of the two bonded cap pieces can be aligned with each other. When the cap piece is placed on the workbench 11 and is ready for sewing, the third positioning mechanism 74 will accurately locate the edge position of the cap piece to ensure that they remain aligned during the sewing process. In addition, the sewing device 50 is also equipped with a third pressing mechanism 52. The third pressing mechanism 52 is movably arranged on the workbench 11, and can be lowered when needed to press the cap piece against the workbench 11. Meanwhile, during the sewing process, the third pressing mechanism 52 can also drive the cap piece to slide along the sewing track on the sewing table of the second sewing mechanism 51. This design not only prevents the cap piece from moving or deflecting during the sewing process, but also ensures the smooth progress of the sewing process.

[0110] In summary, the third positioning mechanism 74, the second sewing mechanism 51 and the third pressing mechanism 52 together constitute the core part of the sewing device 50. The third positioning mechanism 74 ensures the precise alignment of the cap piece edge, and the third pressing mechanism 52 ensures the stability of the cap piece during the sewing process. This design not only improves the automation level of the cap piece sewing machine, but also further improves the product quality and production efficiency.

[0111] Further, refer to Figure 5 as well as Figure 7 In some embodiments of the present invention, the third positioning mechanism 74 includes: a pushing piece 741 and an alignment piece 742. The pushing piece 741 is arranged below the second sewing mechanism 51. The pushing piece 741 includes a pushing rod. The pushing rod is movably arranged below the second sewing mechanism 51; the alignment piece 742 is arranged below the second sewing mechanism 51 and is located on one side of the pushing piece 741. The alignment piece 742 includes more than three fourth positioning rods 7421. The fourth positioning rods 7421 can be raised and lowered through the workbench 11. The fourth positioning rods 7421 are located on the outer peripheral side of the cap piece. The pushing rod is configured to push the cap piece into the alignment piece 742 so that the alignment piece 742 aligns the edges between the two cap pieces.

[0112] The third positioning mechanism 74 is mainly composed of a pusher 741 and an alignment member 742. The pusher 741 is arranged below the second sewing mechanism 51, and its core component is a pusher rod. The pusher rod is movably arranged below the second sewing mechanism 51, and can be extended when needed to push the cap piece to a specified position. The alignment member 742 is located on one side of the pusher 741 and is also arranged below the second sewing mechanism 51. The alignment member 742 includes more than three fourth positioning rods 7421, which can be lifted and lowered through the sewing table of the second sewing mechanism 51 and are located on the outer peripheral side of the cap piece. When the cap piece is pushed into the alignment member 742 by the pusher rod, the fourth positioning rod 7421 will rise and contact the edge of the cap piece, thereby aligning the edges between the two cap pieces. In the specific working process, when two well-fitted cap pieces are placed on the sewing table of the second sewing mechanism 51 and are ready for sewing, the pusher rod will first extend to push the cap piece to the position of the alignment member 742. Then, the fourth positioning rod 7421 rises and contacts closely with the edge of the cap piece, ensuring that the edges of the two cap pieces can be aligned with each other. This design not only improves the accuracy of sewing, but also ensures that the sewn cap pieces have a neat and beautiful appearance.

[0113] Reference Figure 1 as well as Figure 8 In some embodiments of the present invention, the cap piece sewing machine further includes a discharge device 80, which is disposed on the frame 10 and is located on one side of the sewing device 50. The discharge device 80 is configured to deliver the two sewn cap pieces out of the sewing device 50.

[0114] The cap piece sewing machine further includes a discharging device 80, which is arranged on the frame 10 and is located on one side of the seaming device 50. The main function of the discharging device 80 is to smoothly and efficiently send the two sewn cap pieces out of the seaming device 50 for subsequent processing or packaging.

[0115] In the specific workflow, after the two cap pieces are stitched in the seaming device 50, they will be conveyed to the position of the discharge device 80. The discharge device 80 usually includes a series of conveyor belts, rollers or other conveying mechanisms such as clamps, which can work together to smoothly deliver the stitched cap pieces out of the seaming device 50. In order to ensure smooth and accurate discharge, the design of the discharge device 80 fully considers the size, shape and material properties of the cap pieces. The speed, position and spacing of the conveyor belt or roller can be adjusted according to actual needs to ensure that the cap pieces will not be damaged or deformed during the discharge process.

[0116] Specifically, refer to Figure 1 as well as Figure 8In some embodiments of the present invention, the discharging device 80 includes a first clamping mechanism 81, a storage bin 82, and a lifting plate 83. The first clamping mechanism 81 is disposed on the workbench 11, and is configured to clamp the two sewn cap pieces. The storage bin 82 is disposed on one side of the first clamping mechanism 81, and is used to store the cap pieces. The lifting plate 83 is escalably disposed in the storage bin 82, and is configured to support the cap pieces and place the cap pieces in the storage bin 82.

[0117] The discharging device 80 includes a first clamping mechanism 81, a storage bin 82 and a lifting plate 83. The first clamping mechanism 81 is arranged on the workbench 11, adjacent to the sewing device 50. After the two cap pieces are sewn together in the sewing device 50, the first clamping mechanism 81 will quickly clamp the sewn cap pieces to ensure that they will not be scattered or shifted during the subsequent transmission process. The storage bin 82 is arranged on one side of the first clamping mechanism 81 for storing the sewn cap pieces. The design of the storage bin 82 fully considers the storage requirements and space utilization of the cap pieces, and can accommodate a certain number of cap pieces while keeping the cap pieces neat and orderly. In the storage bin 82, a lifting plate 83 that can be lifted and lowered is also arranged. The main function of the lifting plate 83 is to support the cap pieces and put them into the storage bin 82 smoothly. When the first clamping mechanism 81 transfers the sewn cap pieces to the mouth of the storage bin 82, the lifting plate 83 will rise, catch the cap pieces and descend to place them in the storage bin 82. Subsequently, the lifting plate 83 will be withdrawn from the storage bin 82 and rise to prepare for the placement of the next cap piece.

[0118] According to the sewing method of the second aspect of the present invention, the cap piece sewing method is applied to a cap piece sewing machine, and the cap piece sewing mechanism can refer to any one of the embodiments of the first aspect and the embodiment of the first aspect. Figures 1 to 8 The cap piece sewing method comprises the following steps:

[0119] The cap piece sewing machine comprises a feeding device 20, which comprises two lifting and lowering gripping mechanisms 21, two supporting mechanisms 22 and a first sliding mechanism 23. The two gripping mechanisms 21 are arranged on the output end of the first sliding mechanism 23. The first sliding mechanism 23 is configured to drive the gripping mechanisms 21 to move. The two gripping mechanisms 21 are arranged symmetrically. The positions of the two gripping mechanisms 21 correspond to the positions of the two supporting mechanisms 22 one by one. The two cap pieces are placed on the supporting mechanisms 22 respectively.

[0120] Sewing the embroidery eyes of the two cap pieces in sequence; the cap piece sewing machine includes an embroidery eye device 30, which is located on one side of the feeding device 20, and the feeding device 20 conveys the two cap pieces to the embroidery eye device 30, and the embroidery eye device 30 is configured to sew the embroidery eyes on the cap piece;

[0121] The cap piece sewing machine further comprises a bonding device 40, which is located on one side of the eyelet device 30, and is configured to relatively flip the symmetrically placed cap pieces so that the two cap pieces are bonded to each other;

[0122] Sewing two cap pieces that are attached to each other; the cap piece sewing machine also includes a sewing device 50, which is located on the other side of the attaching device 40, and the sewing device 50 is configured to sew the two cap pieces together; and

[0123] Conveying cap pieces; the cap piece sewing machine includes a feeding device 60, which is arranged on one side of the embroidery eye device 30, the laminating device 40 and the seaming device 50, and the feeding device 60 is configured to convey the cap pieces from the embroidery eye device 30, the laminating device 40 and the seaming device 50 in sequence.

[0124] The cap piece sewing method of the present invention is specially applied to a cap piece sewing machine with an exquisite design. The method covers a series of orderly and efficient steps, ensuring that the whole process from grabbing to sewing of the cap piece can maintain high quality and high efficiency.

[0125] First, the method starts with grabbing and conveying two cap pieces at the same time. The two cap pieces are placed symmetrically to ensure the smooth progress of subsequent processing steps. The feeding device 20 of the cap piece sewing machine is responsible for this task, which includes two liftable grabbing mechanisms 21, two supporting mechanisms 22 and a first sliding mechanism 23. The two grabbing mechanisms 21 are arranged at the output end of the first sliding mechanism 23 and are driven to move by the first sliding mechanism 23. The grabbing mechanisms 21 are symmetrically arranged and correspond to the positions of the supporting mechanisms 22 one by one. The cap pieces are placed on the supporting mechanisms 22 respectively, and then grabbed by the grabbing mechanisms 21 and conveyed to the next process.

[0126] Next, the embroidery eyes of the two cap pieces are sewn in sequence. The embroidery eye device 30 of the cap piece sewing machine is located on one side of the feeding device 20, and is responsible for receiving and sewing the embroidery eyes on the cap piece. The feeding device 20 accurately conveys the two cap pieces to the embroidery eye device 30, and the embroidery eye device 30 sews the embroidery eyes of the two cap pieces according to a predetermined program.

[0127] Then, the two symmetrically placed cap pieces are bonded. This step is completed by a bonding device 40 of the cap piece sewing machine, which is located on one side of the eyelet device 30. The bonding device 40 is configured to relatively flip the symmetrically placed cap pieces so that they bond with each other. In this process, the bonding device 40 ensures accurate alignment and tight bonding between the cap pieces.

[0128] Next, the two cap pieces that are attached to each other are sewn together. The sewing device 50 is located on the other side of the attaching device 40. The sewing device 50 is configured to sew the two cap pieces together, and ensure the firmness and beauty of the sewn part through precise sewing technology.

[0129] Finally, cut the sewn cap pieces.

[0130] It should be noted that the step of conveying the cap pieces is as follows: the feeding device 60 of the cap piece sewing machine is arranged on one side of the eyelet device 30, the laminating device 40 and the seaming device 50, and is responsible for conveying the cap pieces from the three devices in sequence. The feeding device 60 ensures the smooth flow of the cap pieces during the processing and improves the overall production efficiency.

[0131] In summary, it can be understood that the cap piece sewing method according to the embodiment of the present invention has at least the following beneficial effects: the cap piece sewing method is applied to a cap piece sewing machine, the feeding device 20 grabs two cap pieces to the embroidery eye device 30, the embroidery eye device 30 sews the embroidery eyes of the two cap pieces in turn, and the cap pieces are transported by the feeding device 60, and the cap pieces are transferred from the embroidery eye device 30 to the laminating device 40, and the laminating device 40 laminates the two cap pieces, and then sews them through the sew device 50. The cap piece sewing machine can replace manual work to sew the embroidery eyes of the two cap pieces and sew the two cap pieces at the same time.

[0132] In some embodiments of the present invention, the cap piece sewing machine further includes a positioning device, the positioning device is located in the feeding device 20, the embroidery eye device 30, the laminating device 40 and the sewing device 50, and the positioning device is configured to locate the position of the cap piece; wherein the positioning device includes a first positioning mechanism 71, a first positioning rod 711 and a plurality of first limiting rods 712, the first positioning rod 711 is passed through the supporting mechanism 22 and inserted into the embroidery eye of the cap piece, and the plurality of first limiting rods 712 are located on the outer peripheral side of the cap piece;

[0133] The steps of simultaneously grabbing and conveying two cap pieces include the following steps:

[0134] After the grabbing mechanism 21 grabs the cap piece, it drives the cap piece to rise to the height of the first positioning rod 711 and the first limiting rod 712, so that the cap piece is separated from the first positioning mechanism 71;

[0135] The first sliding mechanism 23 drives the grabbing mechanism 21 to move toward the embroidery eye device 30 , so that the grabbing mechanism 21 places the cap piece on the embroidery eye device 30 .

[0136] The cap piece sewing machine of the present invention is also provided with a positioning device, which is distributed in the feeding device 20, the eyelet device 30, the fitting device 40 and the seaming device 50. Its core function is to accurately position the cap piece to ensure that each processing step can be carried out accurately.

[0137] In the positioning device, the first positioning rod 711 of the first positioning mechanism 71 and the first limiting rods 712 cooperate with the feeding device 20 to achieve accurate positioning of the cap piece. Specifically, the first positioning rod 711 is inserted into the supporting mechanism 22 and inserted into the eyelet of the cap piece. This design not only stabilizes the position of the cap piece, but also provides an accurate positioning reference for subsequent eyelet sewing. At the same time, the first limiting rods 712 are located on the outer peripheral side of the cap piece to ensure that the cap piece will not deviate from the predetermined position during the processing.

[0138] In the step of simultaneously grabbing and conveying two cap pieces, the positioning device plays a vital role. After grabbing the cap piece, the grabbing mechanism 21 will drive the cap piece to rise to the height of the first positioning rod 711 and the first limiting rod 712. In this process, the cap piece will gradually break away from the direct constraint of the first positioning mechanism 71, and after the precise positioning of the first positioning rod 711 and the first limiting rod 712 and the stable grabbing of the grabbing mechanism 21, the position of the cap piece remains stable and accurate.

[0139] Then, the first sliding mechanism 23 is activated, driving the grabbing mechanism 21 to move toward the embroidery eye device 30. During this movement, the grabbing mechanism 21 firmly grasps the cap pieces to ensure that they will not fall off or shift due to movement. Finally, the grabbing mechanism 21 accurately places the cap pieces on the embroidery eye device 30, making full preparations for the next embroidery eye sewing step.

[0140] In some embodiments of the present invention, the embroidery eye device 30 includes a first sewing mechanism 31 and a first pressing mechanism 32, the first sewing mechanism 31 is configured to sew the embroidery eye on the cap piece, the first pressing mechanism 32 is configured to press the cap piece against the bottom of the first sewing mechanism 31, the positioning device includes a second positioning mechanism 72, the second positioning mechanism 72 is provided with two, the two second positioning mechanisms 72 are arranged below the first pressing mechanism 32, the second positioning mechanism 72 is configured to position the embroidery eye of the cap piece, the second positioning mechanism 72 includes a second lifting member 721 and a second positioning rod 722, the second positioning rod 722 is arranged on the output end of the second lifting member 721, and the second lifting member 721 is configured to drive the second positioning rod 722 to be inserted into the embroidery eye of the cap piece;

[0141] The step of sewing the embroidery eyes of the two cap pieces in sequence also includes the following steps:

[0142] The second lifting member 721 drives the second positioning rod 722 to rise, so that the second positioning rod 722 is inserted into the eyelet of the cap piece;

[0143] The first pressing mechanism 32 presses the cap piece against the sewing table of the first sewing mechanism 31;

[0144] The second lifting member 721 drives the second positioning rod 722 to descend, so that the second positioning rod 722 is pulled away from the eye of the cap piece;

[0145] The first pressing mechanism 32 presses the cap piece and drives the cap piece to slide on the sewing table of the first sewing mechanism 31 , and the first sewing mechanism 31 sews the embroidery eyes of the two cap pieces in sequence.

[0146] On the basis of the cap piece sewing method of the above-mentioned embodiment, the design of the eyelet device 30 further refines the eyelet sewing process, ensuring the accurate sewing of the cap piece eyelets. The eyelet device 30 is mainly composed of a first sewing mechanism 31 and a first pressing mechanism 32, which work together to achieve efficient sewing of the cap piece eyelets. The first sewing mechanism 31 is configured to accurately sew the eyelets on the cap piece. The first pressing mechanism 32 is responsible for firmly pressing the cap piece against the bottom of the first sewing mechanism 31 and driving the cap piece to slide along the sewing track on the sewing table of the first sewing mechanism 31, ensuring that the cap piece will not move or deform during the sewing process and that the sewing of the eyelets is carried out smoothly.

[0147] In order to further improve the accuracy of eyelet sewing, two second positioning mechanisms 72 are specially provided in the positioning device.

[0151] The step of laminating two symmetrically placed cap pieces also includes the following steps:

[0152] The second pressing mechanism 44 presses the cap piece against the flip plate 43;

[0153] The driving member drives the fixing member, and the fixing member passes through the flip plate 43 and contacts the cap piece, so that the fixing member fastens the cap piece on the flip plate 43;

[0154] The two flip plates 43 flip relative to each other so that the two cap pieces fit together, and the driving member drives the fixing member so that the fixing member releases the cap piece.

[0155] Under the framework of the cap piece sewing method of the aforementioned embodiment, the fitting device 40 realizes the precise fitting of two cap pieces. The fitting device 40 includes a reversible flip plate 43 and a second pressing mechanism 44, the cooperation of which ensures the efficiency and accuracy of the cap piece fitting process. There are two flip plates 43, which are arranged symmetrically and initially both remain in a horizontal state. Such a design enables the two cap pieces to be placed stably on the flip plate 43, ready for the subsequent fitting operation. The flip plate 43 has the function of relative flipping, which is the key to achieving the fitting of the cap pieces.

[0156] The second pressing mechanism 44 is located above the flip plate 43.

Then, the driving member drives the fixing member to pass through the flip plate 43 and approach and fit closely or insert the cap piece, providing a precise position reference for fitting and preventing the position of the cap piece from slipping during the flipping process.

[0158] Then, when the two flip plates 43 flip relative to each other, driving the two cap pieces to approach each other and finally fit together, the driving member drives the fixing member to release the eyelets of the cap piece. In this process, the precise positioning of the fixing mechanism 73 ensures the accuracy and consistency of the cap piece fitting.

[0160] The steps of sewing two cap pieces that are attached to each other include the following steps:

[0161] The pushing member 741 pushes the cap piece into the aligning member 742, so that the aligning member 742 aligns the edges between the two cap pieces;

[0162] The third pressing mechanism 52 presses the cap piece against the sewing table of the second sewing mechanism 51 at least once;

[0163] The fourth positioning rod 7421 descends to below the sewing table of the second sewing mechanism 51;

[0164] The third pressing mechanism 52 presses the cap piece and drives the cap piece to slide on the sewing table of the second sewing mechanism 51 , and the second sewing mechanism 51 sews the two cap pieces together.

[0165] On the basis of the cap piece sewing method described in the aforementioned embodiment, the design of the sewing device 50 further improves the sewing process of the cap piece.

[0168] Finally, the third pressing mechanism 52 continues to press the cap piece and drives the sewing table of the cap piece on the second sewing mechanism 51 to slide along the sewing track. The second sewing mechanism 51 sews the two cap pieces according to the predetermined procedure. In this process, the precise alignment of the third positioning mechanism 74 and the stable pressing of the third pressing mechanism 52 jointly ensure the accuracy and consistency of the sewing.
