Description

Technical Field

[0001] The invention relates to the field of quilting processing, and in particular to a method for switching the number of needles of a quilting pattern and related equipment. Background Art

[0002] In the process of quilting patterns, it is inevitable to encounter problems such as broken threads and missing threads. Therefore, it is necessary to move the quilting head to the position where the pattern has problems for repairing. The position of quilting patterns is usually described by the number of needles. For example, if a pattern has 3000 needles and there is a missing thread problem when quilting to 1000 needles, and the problem is found and stopped at 1300 needles, the head needs to be repositioned to 1000 needles before continuing quilting. Therefore, quickly positioning the head to the problem point can greatly improve the efficiency of quilting work.

[0003] Traditional machine head moving method: press and hold the forward or backward button, the machine head moves forward or backward along the pattern track until the machine head moves to the problem point. Since the machine head also moves with it, this method is relatively slow; another method is to press and hold the forward or backward button, the machine head does not move, the pattern position recorded in the software moves forward or backward along the pattern track, and after the position is determined, the machine head moves directly to the problem point. Although this method searches for the problem point slightly faster than the previous method, it is not easy to accurately locate near the problem point.

[0004] Therefore, the prior art still needs to be improved and developed. Summary of the invention

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".

[0054] In the process of quilting patterns, it is inevitable to encounter problems such as broken threads and missing threads. Therefore, it is necessary to move the quilting head to the position where the pattern has problems for repairing. The position of quilting patterns is usually described by the number of needles. For example, if a pattern has 3000 needles and there is a missing thread problem when quilting to 1000 needles, and the problem is found and stopped at 1300 needles, the head needs to be repositioned to 1000 needles before continuing quilting. Therefore, quickly positioning the head to the problem point can greatly improve the efficiency of quilting work.

[0055] For this purpose, see Figure 1 The first aspect of the present invention provides a method for switching the number of needles of a quilting pattern, comprising the steps of:

[0056] S100, forming a pattern linked list based on the actual position data of the pattern to be quilted and the quilting parameter data; in the present invention, before quilting is started, the system software will calculate the actual position of the quilting pattern according to the preconditions such as margins and limits and combine it with the quilting parameter data to form a pattern linked list, and each data node in the pattern linked list is the smallest information unit, which includes basic information such as position and number of stitches.

[0057] S200, storing the pattern list in the pattern layer of the quilting system; in the present invention, the pattern layer is used to store the actual processing data of the machine head (ie, the data of the pattern list), and the machine head will move according to the pattern list.

[0058] S300, generating a pattern corresponding to the pattern linked list in the pixel layer of the quilting system display screen by linear mapping; in the present invention, the pattern linked list maps the linked list data of the pattern layer to the pixel layer of the system display screen by linear mapping, so that the pattern pattern can be displayed on the screen. In the present invention, the mapping relationship between the pixel layer and the pattern layer can be as follows: Figure 2 shown.

[0059] S400, receiving a user's click on a target position in the pixel layer, and generating a position search box; when, for example, quilting needs to be repaired during the quilting process, the user only needs to click the screen near the problem point of the pattern path in the pixel layer (that is, the pixel layer, specifically, it can be double-clicked, the method can be through a mouse or directly using the touch function of the screen), and the system screen will form a square search box at the click position. The process can be specifically as follows Figure 3 That is, in some optional embodiments of the first aspect of the present invention, the receiving a user's click on a target position in the pixel layer and generating a position search box includes: receiving a user's double-click touch on the display screen of the quilting system, or a user's double-click operation in the pixel layer through a mouse; obtaining a target position corresponding to the double-click touch or the double-click operation in the pixel layer; and generating a position search box of preset specifications with the target position as the center.

[0060] S500, based on the mapping relationship between the position search box and the pattern pattern and the pattern linked list, obtain the actual target position of the machine head movement and the target number of quilting needles. In the present invention, there are two ways to obtain the actual target position of the machine head movement and the target number of quilting needles based on the position search box. The first is to find the target pixel point in the system screen pixel layer, and then map it to the pattern layer to find the target data node in the pattern linked list. The second is to map the position search box to the pattern layer, and then find the intersection of the position search box and the pattern linked list and filter to obtain the target data node.

[0061] Taking the second example, in some optional implementations of the first aspect of the present invention, obtaining the actual target position of the machine head movement and the target number of quilting needles based on the mapping relationship between the position search box and the pattern pattern and the pattern chain list includes:

[0062] S501, mapping the position search box to the pattern layer; in some optional implementations of the first aspect of the present invention, mapping the position search box to the pattern layer includes: calculating, based on the center point position of the position search box and preset specifications of the position search box, first position coordinates, second position coordinates, third position coordinates and fourth position coordinates of four corners of the position search box in the pixel layer coordinate system; using the linear mapping relationship formula between the pattern layer and the pixel layer to obtain the first position coordinates, the second position coordinates, the third position coordinates and the fourth position coordinates corresponding to the fifth position coordinates, the sixth position coordinates, the seventh position coordinates and the eighth position coordinates in the pattern layer; and establishing a closed figure of the fifth position coordinates, the sixth position coordinates, the seventh position coordinates and the eighth position coordinates in the pattern layer.

[0063] S502, obtaining a data node set in the pattern linked list contained in the position search box; in some optional implementations of the first aspect of the present invention, obtaining the data node set in the pattern linked list contained in the position search box includes: obtaining the horizontal coordinate range and the vertical coordinate range defined by the closed figure in the coordinate system of the pattern layer; performing a primary screening on all data nodes in the pattern linked list based on the horizontal coordinate range to obtain a primary screening data node set; performing a secondary screening on the primary screening data node set based on the vertical coordinate range to obtain a refined screening data node set, and using the refined screening data node set as the data node set in the pattern linked list contained in the position search box.

[0064] S503, obtaining the first target data node closest to the center point of the location search box from the data node set; in some optional implementations of the first aspect of the present invention, obtaining the first target data node closest to the center point of the location search box from the data node set includes: calculating the distance between each data node in the data node set and the center point of the location search box, and obtaining the calculated distance between each data node in the data node set and the center point of the location search box; filtering the minimum distance from the calculated distance set between each data node and the center point of the location search box, and using the data node corresponding to the minimum distance as the first target data node.

[0065] S504, based on the position data and needle number data bound to the first target data node as the actual target position of the machine head movement and the target number of quilting needles. In general, the overall process of steps S501 to S504 can be understood as: when quilting needs to be repaired during the quilting process, the user only needs to double-click the screen (pixel layer) near the problem point, and a square search box will be formed at the double-click position. The search box is then mapped to the pattern layer, and by comparing it with the linked list data, the linked list data nodes included in the search box are obtained. Compare the positions of these nodes to obtain the data node closest to the center of the search box, and at this point, the target number of needles and position to be jumped can be obtained.

[0066] Taking the first mode as an example, in other optional implementations of the first aspect of the present invention, obtaining the actual target position of the machine head movement and the target number of quilting needles based on the mapping relationship between the position search box and the pattern pattern and the pattern chain list includes:

[0067] S501', obtaining a pixel point set contained in the position search box in the pixel layer; in this step of the present invention, the intersection (ie, pixel point set) of the position search box and the pixel points of the pattern image is obtained in the pixel layer.

[0068] S502', obtaining the target pixel point closest to the center point of the position search box from the pixel point set; in this step, the method of calculating the distance can be the same as the second method, that is, calculating the distance between each pixel point in the pixel point set and the center point of the position search box, and then obtaining the pixel point with the smallest distance value to the center point of the position search box.

[0069] S503', mapping the target pixel point to the pattern layer, and obtaining the second target data node corresponding to the target pixel point in the pattern linked list; in the present invention, the pattern pattern and each point in the pattern linked list are one-to-one corresponding, and after obtaining the target pixel point, the second target data node is obtained according to the correspondence between the pattern pattern and each point in the pattern linked list.

[0070] S504', taking the position data and needle number data bound to the second target data node as the actual target position of the machine head and the target needle number of quilting. In the present invention, each data node in the pattern linked list contains at least two kinds of information: position and needle number.

[0071] In order to better understand the technical effects of the present invention, Figure 2For example, the machine head quilts a circular pattern counterclockwise. When quilting to point A, the thread breaks and the machine does not stop until it moves to point B. After the quilter has threaded the thread, the machine head needs to move from point B to point A. The traditional method requires moving along the circular pattern trajectory (i.e., the red path segment) until it reaches point A. However, the technology used in this article only requires double-clicking near point A to determine the position of point A and move directly to point A along a straight path (i.e., the dotted path segment). This article proposes a technology for quickly jumping the number of pattern needles. Based on the touch screen display of the quilting pattern, you only need to double-click near the problem point to quickly locate it near the problem point. The operation method is simpler, and it saves the time of long pressing the empty forward and empty backward buttons, which is more efficient.
