[0031] Cut pieces can be small pieces or fragments obtained when cutting cloth or other materials, and are one of the basic materials for making products. The shape, size and material of cut pieces will vary according to the specific product design and requirements. Furthermore, cut pieces can be individual parts cut from cloth according to the patterns on the clothing design drawings, such as the front and back of the clothes, sleeves, pockets, etc. After these cut pieces are cut, they need to go through processes such as sewing and decoration, and finally assembled into complete clothing.

[0032] Sewing pieces is one of the steps in the sewing process to join multiple pieces together to form a complete fabric or product. In traditional technology, the process of sewing pieces includes the following steps: (1) Manually spread the curled edge of the front piece to make it flat and ensure that the edges of the piece are neat. (2) Place the spread front piece on the sewing machine and ensure that the sewing line position of the piece is aligned with the needle of the sewing mechanism. This ensures that the piece will not shift or misalign during sewing. (3) Use the sewing machine to insert the needle into the fabric of the piece in a needle-to-hole manner. (4) Insert the entire front piece into the sewing machine one by one and sew along the edge of the piece. (5) After completing the sewing of the front piece, insert the back piece into the sewing machine in the same way and align it with the front piece.

[0033] For pieces with large holes such as sweaters, it is difficult to maintain the alignment between the needle of the sewing mechanism and the hole of the piece manually during the stitching operation. In order to solve the problem that the needle of the sewing mechanism is difficult to accurately insert into the hole of the piece when stitching the pieces, the present application provides a stitching device. Figure 1 , Figure 1The schematic diagram of the structure of the alignment stitching device in one embodiment of the utility model is shown. The alignment stitching device provided in one embodiment of the utility model includes a carrier 10, a sewing mechanism 20, an identification mechanism 30 and a clamping mechanism 40. The carrier 10 is used to place the cut piece, the sewing mechanism 20 includes a sewing needle for sewing the cut piece, and is used to sew the cut piece through the sewing needle to perform the stitching operation, the identification mechanism 30 is used to identify the hole of the cut piece and the position of the sewing needle of the sewing mechanism 20 to ensure the sewing accuracy, and the clamping mechanism 40 is used to clamp the cut piece to facilitate the movement of the cut piece. Optionally, the clamping mechanism 40 can clamp the two sides of the cut piece, close to each other to reduce the hole, and away from each other to increase the hole.

[0034] The sewing mechanism 20 includes a sewing needle and a driving structure, and the driving structure is used to drive the needle to reciprocate and sew the cut piece. In the stitching operation, the sewing needle of the sewing mechanism 20 passes through the hole of the cut piece to sew. Optionally, the sewing is performed according to the stitching process of one needle and one hole. Each needle needs to pass through a fixed hole in the cut piece, and then the needle is sewn continuously. In this way, the spacing between the stitches is usually equal, so the stitches are neat and dense.

[0035] The recognition mechanism 30 is used to detect the first position of the hole on the cut piece and the second position of the needle on the sewing mechanism 20, so that the clamping mechanism 40 can adjust the position of the cut piece based on the first position and the second position. Optionally, the first position and the second position are both their projected positions on the carrier 10. In one implementation, the recognition mechanism 30 can determine the first position and the second position by taking pictures of the cut piece and the sewing mechanism 20. In another implementation, the recognition mechanism 30 can also be provided with a position sensor to respectively detect the position of the hole on the cut piece and the position of the sewing needle of the sewing mechanism.

[0036] The clamping mechanism 40 is in communication connection with the identification mechanism 30, and moves the cut piece based on the first position and the second position so that the hole of the cut piece is located within the insertable range of the sewing needle in the sewing mechanism 20. When the hole of the cut piece is within the insertable range, the sewing needle of the sewing mechanism 20 can pass through the hole to achieve sewing. If the hole of the cut piece is outside the insertable range, the needle cannot be inserted into the hole of the cut piece, resulting in the hole being missed during seaming, thereby reducing the seam quality.

[0037] In the above-mentioned alignment stitching device, the carrier 10 is used to place the cut pieces, the sewing mechanism 20 is used to sew the cut pieces and perform stitching operations, the identification mechanism 30 is used to identify the positions of the holes of the cut pieces and the needles of the sewing mechanism 20 to ensure the accuracy of sewing, and the clamping mechanism 40 is used to clamp the cut pieces to facilitate the movement of the cut pieces. When performing the stitching operation, the identification mechanism 30 identifies the first position of the hole and the second position of the sewing needle, and transmits the first position information and the second position information to the clamping mechanism 40. The clamping mechanism 40 adjusts the position of the cut piece based on the first position and the second position so that the hole is within the insertable range of the sewing needle, thereby realizing automatic alignment of the needle and the hole, and effectively solving the problem of inaccuracy caused by manual control of the alignment of the needle and the hole.

[0038] Optionally, the communication mode between the clamping mechanism 40 and the identification mechanism 30 can be a wired connection or a wireless connection, wherein the wireless connection can be through Wi-Fi, Bluetooth, infrared, etc. In a feasible implementation, a central processor can also be provided, and the clamping mechanism 40 and the identification structure 30 are simultaneously connected to the central processor for communication. After the identification mechanism 30 determines the first position and the second position, the first position information and the second position information are sent to the central processor, which processes the position information and determines the moving path of the cut piece based on the position information, and then sends the moving signal of the moving path to the clamping mechanism 40, which clamps the cut piece and moves it along the moving path, so that the hole of the cut piece is located within the insertable range of the sewing mechanism needle. Optionally, the central processor can be a computer or other terminal with computing functions.

[0039] In one implementation, the first position and the second position can be represented by a coordinate system. For example, the position of the identification mechanism 30 is taken as the zero point, and the three-dimensional coordinates of the target needle hole on the cut piece are first determined to obtain the first position, and then the three-dimensional coordinates of the sewing needle on the sewing mechanism 20 are determined to obtain the second position. At this time, the identification mechanism 30 can be additionally provided with a distance sensor and an angle sensor. In another implementation, the second position of the needle on the sewing mechanism 20 is taken as the origin, and the first position of the hole on the cut piece is determined based on the relative position relationship.

[0040] Furthermore, the moving direction and moving distance of the cut piece can be obtained based on the relative positional relationship between the first position and the second position. The insertable range of the needle can be determined based on the second position of the sewing needle, and the position of the cut piece can be adjusted through the positional relationship between the first position and the insertable range so that the first position is within the insertable range.

[0041] In an exemplary embodiment, the alignment stitching device further includes a deviation correction mechanism 50, which clamps the cut piece and is used to move the cut piece according to the first position and the second position so that the first sewing line on the cut piece matches the second sewing line of the sewing mechanism 20. Optionally, the deviation correction mechanism 50 can be provided with a gripper or a clamping plate, and the cut piece is clamped by the gripper or the clamping plate to facilitate the movement of the cut piece. The second sewing line on the sewing mechanism 20 is aligned with the first sewing line on the cut piece, which can ensure the accuracy and quality of the stitching. Among them, the first sewing line and the second sewing line match, which can make the obtained product denser.

[0042] The clamping mechanism 40 can make the current target needle hole be located within the insertion range of the sewing needle. The focus is on adjusting the position of the part of the cut piece close to the needle, while the correction mechanism 50 solves the problem of the offset of the cut piece, ensures neat seams and improves the quality of splicing.

[0043] In a feasible implementation, a sensor can be provided on the deviation correction mechanism 50 to detect the position of the first sewing line on the cutting piece and the second sewing line preset on the sewing mechanism 20. The second sewing line can be a trajectory line preset by the sewing mechanism 20. Optionally, the sensor can be a photoelectric sensor, a laser sensor, etc. After the sensor detects the position of the sewing line on the cutting piece, the data is transmitted to the control system for processing. The control system calculates the deviation correction amount that needs to be adjusted based on the sensor data, calculates the deviation correction amount instruction, and controls the deviation correction mechanism 50 to adjust the cutting piece according to the deviation correction amount instruction. After that, the sensor is used again to detect the position of the sewing line on the cutting piece to ensure that the adjusted line is completely aligned with the line on the sewing mechanism 20, that is, on the same axis.

[0044] In an exemplary embodiment, the alignment stitching device further includes an anti-curling mechanism 60. The anti-curling mechanism 60 is used to prevent the cut piece from curling or loosening during the sewing process, and in particular to prevent the edge of the cut piece from curling and causing obstruction. The anti-curling mechanism 60 is disposed on the clamping mechanism 40, and is used to absorb the edge of the cut piece so that the edge of the cut piece fits the carrier 10, thereby preventing the edge of the cut piece from curling and causing obstruction, which causes the recognition mechanism to be unable to determine the first position and the second position in real time.

[0045] During the sewing process, the cut pieces are prone to curling due to their own fragility or uneven tension, which affects the sewing effect and quality. The anti-curling mechanism 60 can effectively prevent the fabric from curling through a series of tension control and guide devices to ensure smooth sewing stitches. Optionally, the anti-curling mechanism 60 can pull the cut pieces or blow air to the cut pieces through a fan to make the cut pieces fit the carrier 10, which is convenient for the identification mechanism 30 to identify the position and improve the efficiency and quality of sewing.

[0046] In some embodiments, the anti-curling mechanism 60 includes a fan, the air outlet of the fan is directed toward the cut piece, and is used to blow air toward the cut piece so that the edge of the cut piece fits the carrier. The air outlet of the fan is directed toward the side of the cut piece that is away from the carrier 10, and the fan is used to blow air toward the cut piece so that the cut piece is subjected to a force from the fan directed toward the carrier 10, so that the cut piece is subjected to the wind force and fits onto the carrier 10. Optionally, a plurality of air holes can be provided on the anti-curling mechanism 60, and the air outlet of the fan is directed toward the air holes so that the blown air can pass through the air holes to the cut piece.

[0047] In an exemplary embodiment, a base 70 is further included, and the carrier 10, the sewing mechanism 20, the identification mechanism 30 and the clamping mechanism 40 are all arranged on the base 70. Optionally, the base 70 can be used as a base to play a supporting role. The carrier 10, the sewing mechanism 20, the identification mechanism 30 and the clamping mechanism 40 are all arranged on the base 70, which can improve stability, maintain the relative stability of the cutting piece and the sewing mechanism 20 during the stitching process, avoid shaking and causing the sewing line to deviate, so as to improve the stitching quality of the cutting piece.

[0048] Optionally, the base 70 is a frame, including a plurality of cross beams 71 and a plurality of longitudinal beams 72, and the plurality of cross beams 71 and the plurality of longitudinal beams 72 are connected to form the frame. Optionally, the plurality of cross beams 71 form two cross beam layers, and the plurality of longitudinal beams 72 connect the two cross beam layers, the bottom cross beam layer is set on the ground, and the top cross beam layer is used to set the carrier 10, the sewing mechanism 20, the identification mechanism 30 and the clamping mechanism 40.

[0049] Optionally, the crossbeam can be a steel structure, which has the advantages of high strength, corrosion resistance and plasticity, and provides stable support and structural strength. The carrier 10, the sewing mechanism 20, the identification mechanism 30 and the clamping mechanism 40 are all arranged on the frame, supported by the frame, and convenient for overall movement.

[0050] In an exemplary embodiment, the alignment stitching device further includes a mounting plate 73, the mounting plate 73 is connected to the plurality of beams 71 at the same time, and the clamping mechanism 40 is disposed on the mounting plate 73. Optionally, the mounting plate 73 is located on the plurality of beams 71 and is fixedly connected to the plurality of beams 71 to improve stability. The clamping mechanism 40 is disposed on the mounting plate 73 to increase the support area of ​​the clamping mechanism 40 and improve its stability.

[0051] See also Figure 2In an exemplary embodiment, the recognition mechanism 30 includes a graphics acquisition component 31 and a graphics processing component 32. The graphics acquisition component 31 is used to acquire an image of the cut piece and an image of the sewing mechanism 20.

[0052] Optionally, the graphics processing component 32 finds the hole and the needle in the image based on a visual recognition algorithm and then selects the frame, determines the insertable range of the needle based on the second position of the needle, and adjusts the position of the cut piece based on the positional relationship between the first position of the hole and the insertable range, so that the hole is located within the insertable range of the needle.

In a feasible embodiment, the clamp includes two pairs of clamping plates, which clamp the two sides of the cut piece respectively, so that the size of the hole on the cut piece can be adjusted by controlling the two clamping plates to move closer to or farther from each other.

[0054] During the stitching operation, the multi-directional motion component adjusts the position of the cut piece through the clamp, inserts the outermost hole of the cut piece into the first needle, and then performs continuous operation through the sewing mechanism 20.
