[0041] Embodiments of the present invention provide a method, device, equipment and storage medium for adjusting the spacing of a multi-head quilting machine.

[0042] The following describes embodiments of the present disclosure in more detail with reference to the accompanying drawings. Although certain embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be construed as limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present disclosure. It should be understood that the drawings and embodiments of the present disclosure are for illustrative purposes only and are not intended to limit the scope of protection of the present disclosure.

[0043] In the description of the embodiments disclosed herein, the term "including" and similar terms should be understood as open inclusion, i.e., "including but not limited to." The term "based on" should be understood as "based, at least in part, on." The term "one embodiment" or "the embodiment" should be understood as "at least one embodiment." The terms "first," "second," etc. may refer to different or the same objects. Other explicit and implicit definitions may also be included below.

[0044] For ease of understanding, the specific process of the embodiment of the present invention is described below. Figure 1 , an embodiment of a method for adjusting the spacing of a multi-head quilting machine in an embodiment of the present invention includes:

[0045] S100: Acquire a multi-head quilting machine pattern, and analyze the multi-head quilting machine pattern to obtain each pattern unit in the pattern.

[0046] In this embodiment, it is first necessary to obtain the pattern files required by the quilting machine. These files are usually stored in a specific format (such as DAT files) and can be generated by the control system of the computer quilting machine or CAD plate-making software. The pattern files can be transferred to the quilting machine via a USB flash drive or other storage device for storage and call. The target quilting image is preprocessed and edge extracted, and then the image is divided into several ordered point contours using a contour tracking algorithm. The data structure in the pattern file is parsed using CAD plate-making software or other special software. By identifying the data structure in the pattern file, the basic graphics elements (such as straight lines and circles) are extracted and converted into instructions that can be recognized by the quilting machine. The stitch points of the pattern are evenly distributed within the threshold range to ensure the quality of quilting, and the basic graphics elements are combined into complete pattern units, and precise sewing is achieved through the control system of the quilting machine. The pattern unit structure is as follows: Figure 2 As shown, each circle represents a pattern unit.

[0047] S200, calculating the position of the first quilting head according to the position of each pattern unit, and calculating the position of each quilting head according to the position of the first quilting head and the position of each pattern unit.

[0048] In this embodiment, the quilting head is a key component for quilting operation, and each quilting head is responsible for embroidering a specific pattern unit on the fabric. Figure 3 As shown, each quilting head corresponds to an origin sensor installed on the frame. In order to ensure the accuracy and consistency of the entire quilting process, the starting position of each quilting head, that is, the origin position, needs to be accurately determined. The function of the origin sensor is to help the head determine its starting position so that it can be accurately aligned when embroidering the pattern. The origin sensor can determine the relative distance of the head by adjusting the installation position. Each head corresponds to an origin sensor. The relative position of the origin sensor is the relative distance of the head. The relative distance of the head can also be determined (changed) by changing the relative lateral distance of the corresponding head from the corresponding origin sensor. First, the position of the first quilting head is calculated based on the position of each pattern unit. The position of this first quilting head is usually a reference starting point for the entire quilting area. Once the position of the first quilting head is determined, the positions of other heads can be calculated based on the position of the first head and the relative positions between them. Specifically, the relative positions of the other machine heads and the first quilting machine head are calculated according to the positions of the various pattern units, and then the positions of the other machine heads are obtained according to the relative positions of the other machine heads and the first quilting machine head.

[0049] S300, generating control instructions according to the positions of each quilting machine head.

[0050] In this embodiment, first, it is necessary to clarify the position of each quilting head, that is, the target starting position of each quilting head, and generate corresponding control instructions based on the current position and target starting position of the quilting head. These instructions need to include parameters such as the distance, direction, and speed that each head needs to move.

[0051] S400, sending a control instruction to the machine head driving system, so that the machine head driving system drives each quilting machine head to the target starting position in sequence.

[0052] In this embodiment, the generated control instructions are sent to the head drive system. The head drive system usually includes components such as a servo motor and a controller, which are responsible for performing specific motion operations. After receiving the control instructions, the head drive system will drive each quilting head to a specified starting position according to the parameters in the instruction. During this process, it is necessary to ensure that each head can accurately reach the target position and maintain stable and precise movement throughout the process. During the whole process, it is also necessary to monitor the movement state of each head in real time and adjust the control instructions based on the feedback information to ensure the accuracy and stability of the movement.

[0053] In an optional embodiment of the first aspect of the present invention, calculating the position of the first quilting head according to the position of each pattern unit, and calculating the position of each quilting head according to the position of the first quilting head and the position of each pattern unit includes:

[0054] The required number of quilting heads is calculated according to each pattern unit; the position of the first quilting head is calculated according to the position of each pattern unit; the position of each quilting head is calculated according to the position of the first quilting head, the positions of each pattern unit and the required number of quilting heads.

[0055] In this embodiment, first, the number of quilting heads required is calculated. According to the number of pattern columns of the current pattern unit, the number of quilting heads required can be determined. For example, if the number of pattern columns of the pattern unit is n, then n quilting heads are required to complete the sewing of the entire pattern unit. Figure 2 As shown, the current pattern has four rows of pattern units, so four quilting heads are required. Next, the position of the first quilting head is calculated based on the position of the first row of pattern units. Assuming the coordinates of the upper left corner of the first row of pattern units are (x0, y0), quilting heads typically need to be aligned with the pattern units. Therefore, the position of the first quilting head can be set to the same as the upper left corner of the first row of pattern units, that is, (x0, y0). Based on the position of the first quilting head and the arrangement of the pattern units, the positions of the remaining quilting heads can be calculated.

[0056] In an optional embodiment of the first aspect of the present invention, calculating the position of the first quilting head according to the positions of each pattern unit includes:

[0057] According to each pattern unit, the position of the first row of pattern units is obtained; according to the position of the first row of pattern units, the position of the first quilting machine head is calculated.

[0058] In this embodiment, the multi-head quilting machine pattern to be processed (such as Figure 2 ) for analysis. Each pattern has a starting point, and multiple heads work simultaneously. Such a pattern has a certain symmetry. The first pattern on the leftmost (or rightmost) side of the pattern is used as the first quilting head position. Specifically, first, it is necessary to clarify the arrangement of the pattern units. The pattern units are arranged according to certain rules. For example, assuming that the pattern units are arranged according to the X-axis and Y-axis, and each pattern unit has a certain coordinate, the coordinate list of a pattern unit is as follows:

[0059] First pattern unit: X=100, Y=1000

[0060] Second pattern unit: X=110, Y=1100

[0061] The third pattern unit: X=100, Y=1120

[0062] The fourth pattern unit: X=200, Y=1000

[0063] From the above data, it can be obtained that the position of the first row of pattern units is X=100. Specifically, the first row of pattern units includes the following coordinates: (100, 1000), (100, 1120).

[0064] Next, the position of the first quilting head needs to be calculated based on the position of the first row of pattern units. The position of the first quilting head is the same as the first position of the first row of pattern units, that is, X=100, Y=1000.

[0065] In an optional embodiment of the first aspect of the present invention, according to the position of the first quilting head, the positions of the pattern units and the required number of quilting heads, calculating the positions of the quilting heads includes:

[0066] Obtain the position of the next row of pattern units adjacent to the first row of pattern units; calculate the coordinate difference between the first quilting head and the next row of pattern units based on the position of the first quilting head and the position of the next row of pattern units; calculate the position of the next quilting head based on the coordinate difference between the first quilting head and the next row of pattern units; obtain the position of the next row of pattern units, and calculate the position of the next quilting head based on the position of the next row of pattern units and the position of the first quilting head, until all required quilting head positions are calculated.

[0067] In this embodiment, first, the position of the first row of pattern units needs to be determined. Then, based on each pattern unit, the position of the next row of pattern units adjacent to it needs to be found. After determining the position of the first quilting head, the coordinate difference between the position of the first quilting head and the next row of pattern units is calculated. For example, if the position of the pattern unit is (x1, y1) and the position of the first quilting head is (x0, y0), the coordinate difference is:

[0068] Δx=x1-x0,Δy=y1-y2

[0069] According to the above coordinate difference, the position of the next quilting head can be calculated. For example, if the position of the first quilting head is (x n ,y n ), then the position of the next quilting machine head is: (x n +Δx,y n +Δy).

[0070] The position of the next row of pattern units is found. Using the position of the next row of pattern units and the position of the first quilting head, the coordinate difference is calculated again and the position of the quilting head is updated. The position of the pattern units in subsequent rows is obtained and the position of each quilting head is calculated, until all the required positions are calculated. Through these steps, the required number of quilting heads and the specific position of each head can be accurately calculated, thus ensuring the efficiency and accuracy of the quilting process.

[0071] In an optional embodiment of the first aspect of the present invention, before obtaining a multi-head quilting machine pattern and parsing the multi-head quilting machine pattern to obtain each pattern unit in the pattern, the method further includes:

[0072] When the multi-head quilting machine is powered on, a zeroing command is sent to the machine head drive system; the machine head drive system drives each quilting head to the corresponding origin sensor position in sequence according to the zeroing command.

[0073] In the present embodiment, each time the multi-head quilting machine is powered on, the system will send a return-to-zero instruction to the head drive system. According to the return-to-zero instruction, the head drive system moves each quilting head to the corresponding origin sensor position in sequence for return to zero. This process ensures that each head can accurately return to its mechanical zero position, thereby ensuring the accuracy and consistency of subsequent processing. Specifically, the return-to-zero operation needs to be carried out according to a certain sequence. First, the leftmost head (the first head) is returned to zero, then the left second head, and so on, until the last head on the right completes the return to zero. This sequential return-to-zero operation is to avoid interference and ensure that each head can be accurately in place. Each time the multi-head quilting machine is powered on, it is necessary to perform the return-to-zero operation again, because power failure will cause the head position memory to be lost, and the return-to-zero operation is the key step to re-establish these memories. After the return to zero is completed, the head can enter normal working state, otherwise it may cause error or equipment failure.

[0074] In an optional embodiment of the first aspect of the present invention, after sending a control instruction to the head drive system so that the head drive system drives each quilting head to the target starting position, the method further includes:

[0075] To adjust the target quilting head position, adjust the first quilting head to the leftmost pattern in the first row of pattern units; adjust the last quilting head to the rightmost pattern in the last row of pattern units; adjust the middle quilting head to the rightmost pattern or the leftmost pattern to adjust the target quilting head to the starting position of the target row of pattern units.

[0076] In this embodiment, when changing the position of the machine head, first adjust the position of the first quilting machine head (the leftmost machine head) so that it reaches the leftmost pattern of the first row of pattern units. Then adjust the last quilting machine head (the rightmost machine head) so that it reaches the rightmost pattern of the last row of pattern units. Then adjust the middle machine head to perform machine head adjustment. Specifically, adjust the middle machine head to the leftmost pattern of the first row of pattern units or the rightmost pattern of the last row of pattern units to adjust the target quilting machine head to the starting position of the target row of pattern units. For example, if the second machine head needs to be adjusted, and the adjusted position coincides with the position of the third machine head, the third machine head needs to be moved to the right first, and then the second machine head needs to be moved to the position it needs to reach, and then the third head needs to be adjusted. In this way, it is ensured that the positions of the machines do not overlap, thereby automatically adjusting the positions.

[0077] In an optional embodiment of the first aspect of the present invention,

[0078] Obtain a multi-head quilting machine pattern and parse the multi-head quilting machine pattern to obtain the pattern units including:

[0079] Obtain a pattern file of a multi-head quilting machine; obtain a pattern of the multi-head quilting machine according to the pattern file; and parse the pattern of the multi-head quilting machine to obtain each pattern unit in the pattern.

[0080] In this embodiment, the pattern file of the multi-head quilting machine can be obtained through various channels. For example, the pattern file can be created and edited through computer quilting machine programming software, the obtained pattern file can be imported into the quilting machine, and the pattern file can be parsed. During the pattern file parsing process, image processing technology can be used to extract the outline of the pattern and vectorize it. For example, through edge detection algorithm and corner point detection algorithm, the complex pattern can be decomposed into basic graphics elements (such as straight lines, arcs, curves, etc.), and the stitch points can be evenly distributed to obtain each pattern unit in the pattern.
