Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present application. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present application, as detailed in the appended claims.

It should be noted that, in this document, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising a … …" does not exclude the presence of another identical element in a process, method, article, or apparatus that comprises the element.

For easy understanding, an application scenario of the embodiment of the present application is described in detail below with reference to fig. 1.

Fig. 1 is a schematic view of an application scenario provided in an embodiment of the present application. Referring to fig. 1, the embroidery machine includes an embroidery machine and a terminal machine. The terminal device can generate a control instruction for controlling the embroidery device and send the control instruction to the embroidery device when the terminal device receives the preset pattern. When the embroidery device receives the control instruction sent by the terminal device, the embroidery device can embroider the preset pattern according to the control instruction.

In the related art, when the embroidering of a partial pattern is completed, the upper thread and the lower thread are cut at a position where the last stitch is ended. At present, the embroidery machine controls the scissors, the hook knife and the thread-buckling fork to complete thread cutting in the last circle of the rotation of the main shaft. However, when the last circle of the rotation of the main shaft is used for cutting the thread, the hook knife needs to hook up the upper thread within a small rotating bucket angle of the main shaft, so that the hook knife can damage the upper thread, and the thread cutting effect of the embroidery machine is poor.

In order to solve the technical problem of poor thread cutting effect of an embroidery machine in the related art, the embodiment of the application provides a thread cutting control method of the embroidery machine, in the process that a main shaft of the embroidery machine rotates from a first rotation angle to a second rotation angle, a hooking knife is controlled to be opened, a scissors is controlled to be opened, and a thread hooking fork is controlled to buckle threads according to the rotation angle of the main shaft, in the process that the main shaft rotates from the second rotation angle to a third rotation angle, the hooking knife is controlled to be stopped, the hooking knife is controlled to be opened, the scissors are controlled to be turned back, and a thread hooking fork is controlled to be opened according to the rotation angle of the main shaft.

The technical means shown in the present application will be described in detail below with reference to specific examples. It should be noted that the following embodiments may exist alone or in combination with each other, and description of the same or similar contents is not repeated in different embodiments.

Fig. 2 is a schematic flow chart of a thread cutting control method of an embroidery device according to an embodiment of the present application.

Referring to fig. 2, the method may include:

s201, in the process that a main shaft of the embroidery device rotates from a first rotation angle to a second rotation angle, according to the rotation angle of the main shaft, opening of a hook knife, opening of a scissors and thread buckling of a thread buckling fork are controlled.

The execution main body of the embodiment of the application can be an embroidery device, and can also be a thread cutting control device of the embroidery device arranged in the embroidery device. Wherein the thread cutting control device of the embroidery device can be realized by the combination of software and/or hardware.

The embroidering apparatus may be any apparatus having an embroidering function. For example, the embroidering apparatus may be an embroidering machine, a computerized embroidering machine, or the like. The embroidery device can comprise a main shaft, a hook knife, scissors and a thread buckling fork. The main shaft is a motion connecting part of a machine head and a machine base of the embroidery equipment and can be divided into an upper shaft and a lower shaft. The main shaft is used for providing power for the embroidery equipment. For example, when the embroidery device works, the upper shaft and the lower shaft of the main shaft can drive various components of the embroidery machine to move through the rotation of the main shaft motor.

Optionally, the embroidery device may control components in the embroidery device according to a rotation angle of the main shaft. For example, when the embroidery machine is in operation, the main shaft rotates 360 degrees, the embroidery machine can embroider a needle on the cloth, when the embroidery machine stops operating, the main shaft stops at the position of 100 degrees, each part of the embroidery machine takes 100 degrees as a reference point, and when the main shaft rotates different angles, the embroidery machine controls each part to embroider.

Optionally, when the embroidery is finished, the embroidery device may receive the deceleration signal of the main shaft, and control the main shaft to decelerate according to the speed regulation signal, so as to improve the effect of thread trimming.

The hook knife is used for pulling the upper thread after finishing thread cutting into the thread clamp. For example, the embroidery machine cuts the thread when the work is completed, and the scissors are disposed under the cloth, so that the embroidery machine needs to control the hook knife above the cloth to pull out the cut upper thread after the scissors cut the thread. Optionally, the hook knife comprises an out hook and a back hook when being opened. For example, collude the sword when starting, collude the sword motor and can control colluding the sword and stretch out, collude the sword motor and can control colluding the sword and return to collude when colluding the sword and extend the below of facial line for the facial line card is located in the card line hole of colluding the sword, and then colludes out facial line from the cloth.

The scissors are used for cutting the thread. For example, after the needle is locked, the embroidery machine may control the scissors to cut the embroidery thread at the position where the last needle is ended, so as to facilitate the subsequent embroidery work. The lock needle is used for fixing the bottom thread and the upper thread. For example, after the embroidery is finished, the embroidery machine needs to embroider 2 short needles with the length of 0.8mm-1.5mm, so that the upper thread and the bottom thread form a firm knot, and the knot can be prevented from loosening after the thread is cut. The bottom thread is an embroidery thread passing through the lower part of the cloth, and the upper thread is an embroidery thread passing through the upper part of the cloth.

Alternatively, the scissors may comprise a fixed blade and a movable blade. The embroidery device can control the moving knife to move, so that the scissors are opened or closed. For example, when the thread cutting starts, the embroidery machine can control the movable knife to move to the position with the largest cutter opening range, and when other components of the embroidery machine control the embroidery thread to enter the thread cutting range of the scissors, the embroidery machine controls the brake knife to move to the initial position, so that the scissors are closed, and the thread cutting process is completed.

Optionally, the cutting edges of the fixed knife and the movable knife are aligned when the knives are closed, so that the embroidery thread can be cut off by the scissors. For example, when the stationary knife and the movable knife are combined, the edge surface of the stationary knife and the edge surface of the movable knife are tightly attached, and the movable knife can be abutted against the stationary knife, so that the stationary knife moves upwards or downwards by a small distance (0.01 mm).

The thread buckling fork is used for fixing the bottom thread. For example, in the thread cutting process, the thread-fastening fork can fasten the bottom thread, so as to control the length of the cut thread.

The difference between the second rotation angle and the first rotation angle is a preset value. For example, the difference between the first rotational angle and the second rotational angle may be 360 degrees, 720 degrees, or the like. Wherein, the first rotation angle can be a reference angle of the embroidery machine. For example, when the embroidery machine is operated, if the embroidery machine controls other embroidery members with reference to 100 degrees of rotation of the main shaft, the first rotation angle may be 100 degrees. Optionally, if the first rotation angle is 100 degrees and the preset value is 360 degrees, the second rotation angle is 460 degrees.

Optionally, in an actual application process, since the maximum rotation scale of the main shaft of the embroidery device is 360 degrees (the main shaft rotates one turn), the first rotation angle and the second rotation angle may be the same on the rotation scale of the main shaft (for example, the preset value is 360 degrees), but if the preset value is 360 degrees, the main shaft rotates 1 turn when the main shaft rotates from the first rotation angle to the second rotation angle, and if the preset value is 720 degrees, the main shaft rotates 2 turns when the main shaft rotates from the first rotation angle to the second rotation angle.

The hooking knife start, the scissors open and the thread-fastening fork can be controlled according to the following feasible implementation modes: when the main shaft rotates to a first angle, the thread buckling fork is controlled to buckle threads, when the main shaft rotates to a second angle, the hooking knife is controlled to be opened, and when the main shaft rotates to a third angle, the scissors are controlled to be opened. The first angle is smaller than the second angle, the second angle may be larger than the third angle, and the second angle may also be smaller than or equal to the third angle. Optionally, the first angle, the second angle and the third angle may be angles that the main shaft rotates in the process of trimming the line. For example, when the embroidery machine uses the scale of the main shaft rotating 100 degrees as a reference, if the first angle is 20 degrees, the second angle is 100 degrees, and the third angle is 190 degrees, when the thread cutting starts, the main shaft of the embroidery machine rotates to 120 degrees to thread the thread fork, the hook knife opens when the main shaft of the embroidery machine rotates to 200 degrees, and the scissors open when the main shaft of the embroidery machine rotates to 290 degrees. For example, since the maximum rotation scale of the main shaft is 360 degrees, if the third angle is 300 degrees, the scissors are opened when the main shaft rotates to 40 degrees.

Optionally, when the embroidery machine cuts threads, the running speed of each component can be determined according to the rotating speed of the main shaft. For example, the rotation speed of the main shaft is proportional to the speeds of the scissors for opening and hooking, and the higher the rotation speed of the main shaft is, the higher the speed of the scissors for opening is, and the higher the speed of the hooking for hooking. For example, if the rotation speed of the main shaft a is rotation speed a and the rotation speed of the main shaft B is rotation speed B, the scissors opening speed controlled by the main shaft a is higher than the scissors opening speed controlled by the main shaft B.

Next, referring to fig. 3, the process of the embroidery device controlling the opening of the hook knife, the opening of the scissors and the thread-hooking fork according to the rotation angle of the main shaft will be described in detail.

Fig. 3 is a schematic diagram of a trimming timing sequence according to an embodiment of the present application. Please refer to fig. 3, which includes the rotation angle of the main shaft, the scissors, the hook and the thread-fastening fork. The main shaft rotation angle is based on 100 degrees (the initial position of the main shaft corresponds to 100 degrees of the main shaft rotation scale), the first angle is 20 degrees, the second angle is 100 degrees, and the third angle is 190 degrees. According to the rotation angle of the main shaft, the scissors are controlled to open, the hook knife is controlled to open, and the thread buckling fork buckles the thread.

Referring to fig. 3, the first angle is 20 degrees, and the embroidering apparatus may control the thread-fastening forking thread when the main shaft rotates to 120 degrees. The second angle is 100 degrees, and when the main shaft rotates to 200 degrees, the embroidery device can control the hook knife to be opened. The third angle is 190 degrees, and when the main shaft rotates to 290 degrees, the embroidery device can control the scissors to open.

S202, in the process that the main shaft rotates from the second rotation angle to the third rotation angle, the hooking knife is controlled to stop, the hooking knife is controlled to be opened, the scissors are controlled to return, and the thread buckling fork is controlled to be opened according to the rotation angle of the main shaft.

And the difference between the third rotation angle and the second rotation angle is the preset value. For example, the difference between the third rotation angle and the second rotation angle is 360 degrees, 720 degrees, or the like. Optionally, the number of turns of the spindle during trimming can be determined according to a preset value. For example, in the process of cutting threads by the embroidery machine, if the preset value is 360 degrees, the main shaft of the embroidery machine rotates 2 circles when rotating from the first rotation angle to the third rotation angle; if the preset value is 540 degrees, the main shaft of the embroidery machine rotates 3 turns when rotating from the first rotation angle to the third rotation angle.

Optionally, in an actual application process, since the maximum rotation scale of the main shaft of the embroidery device is 360 degrees, the rotation scales corresponding to the first rotation angle, the second rotation angle, and the third rotation angle may be the same. For example, if the preset value is 360 degrees, the rotation scales corresponding to the first rotation angle, the second rotation angle and the third rotation angle are the same (if the reference is 100 degrees, the rotation scales corresponding to the first rotation angle, the second rotation angle and the third rotation angle are 100 degrees).

The hooking knife can be controlled to stop, the hooking knife is controlled to open, the scissors return the knife, and the thread buckling fork is controlled to open according to the following feasible implementation modes: when the main shaft rotates to a fourth angle, the hooking cutter is controlled to stop, when the main shaft rotates to a fifth angle, the scissors are controlled to return, when the main shaft rotates to a sixth angle, the thread buckling fork is controlled to open, and when the main shaft rotates to a seventh angle, the hooking cutter is controlled to open. The fourth angle is smaller than the fifth angle, the fifth angle is smaller than the sixth angle, and the sixth angle is smaller than the seventh angle. Optionally, the fourth angle, the fifth angle, the sixth angle and the seventh angle may be angles at which the spindle rotates in the thread trimming process. For example, when the embroidery machine uses a scale of 100 degrees of rotation of the main shaft as a reference, if the fourth angle is 120 degrees, the fifth angle is 290 degrees, the sixth angle is 320 degrees, and the seventh angle is 340 degrees, when the thread cutting starts, the main shaft of the embroidery machine rotates to 220 degrees, the hook stops, when the main shaft of the embroidery machine rotates to 30 degrees, the scissors return, when the main shaft of the embroidery machine rotates to 60 degrees, the thread-fastening fork opens, and when the main shaft of the embroidery machine rotates to 80 degrees, the hook opens.

Next, referring to fig. 4, the process of controlling the hook knife to stop, the hook knife to open, the scissors to return, and the thread take-up fork to open by the embroidery device according to the rotation angle of the main shaft will be described in detail.

Fig. 4 is a schematic diagram of another trimming timing sequence according to an embodiment of the present application. See fig. 4, including the angle of rotation of the main shaft, scissors, hook and thread-fastening fork. The main shaft rotation angle is based on 100 degrees (the initial position of the main shaft corresponds to 100 degrees of the main shaft rotation scale), the fourth angle is 120 degrees, the fifth angle is 290 degrees, the sixth angle is 320 degrees, and the seventh angle is 340 degrees. According to the rotation angle of the main shaft, the hook knife is controlled to stop, the hook knife is controlled to open, the scissors return and the thread buckling fork is controlled to open.

Referring to fig. 4, the fourth angle is 120 degrees, and when the main shaft rotates to 220 degrees, the embroidery device may control the hooking knife to stop. The fifth angle is 290 degrees, and when the main shaft rotates to 30 degrees, the embroidery device can control the back cutting of the scissors. The sixth angle is 320 degrees, and when the main shaft rotates to 60 degrees, the embroidery device can control the thread fastening fork to be opened. The seventh angle is 340 degrees, and when the main shaft rotates to 80 degrees, the embroidery device can control the hook knife to be opened again.

The embodiment of the application provides a thread cutting control method of embroidery equipment, which is characterized in that in the process that a main shaft of the embroidery equipment rotates from a first rotation angle to a second rotation angle, when the main shaft rotates to the first angle, a thread-fastening fork and a thread are controlled, when the main shaft rotates to the second angle, a hook knife is controlled to be opened, and when the main shaft rotates to a third angle, a scissors is controlled to be opened, wherein the difference between the second rotation angle and the first rotation angle is a preset value, and the first angle is smaller than the second angle. In the process that the main shaft rotates to a third rotating angle from a second rotating angle, when the main shaft rotates to a fourth angle, the hooking knife is controlled to stop, when the main shaft rotates to a fifth angle, the scissors are controlled to return, when the main shaft rotates to a sixth angle, the buckling fork is controlled to open, when the main shaft rotates to a seventh angle, the hooking knife is controlled to open, wherein the difference between the third rotating angle and the second rotating angle is a preset value, the fourth angle is smaller than the fifth angle, the fifth angle is smaller than the sixth angle, and the sixth angle is smaller than the seventh angle. In the method, when the preset value is 360 degrees, the difference between the first rotating angle and the third rotating angle is 720 degrees, namely, the embroidery equipment finishes the thread cutting process in the process of rotating the main shaft for the last two circles, so that the thread hooking knife can hook threads at a more reasonable angle, the damage to the threads in the thread cutting process is avoided, and the thread cutting effect of the embroidery machine is further improved.

On the basis of the embodiment shown in fig. 2, the embroidery device further comprises a surface clamp and an embroidery frame, and the control process of the surface clamp and the embroidery frame when the embroidery device cuts thread is described in detail below with reference to fig. 5.

FIG. 5 is a flowchart illustrating a control surface clip and an embroidery frame according to an embodiment of the present application. Referring to fig. 5, the method may include:

s501, acquiring the state of the hook knife and the state of the scissors.

The state of the hook knife can be that the hook knife is opened or the hook knife returns to hook. For example, if the hooking knife is in an open state, the hooking knife motor can control the hooking knife to extend out; if the state of the hook knife is that the hook knife returns to hook, the hook knife motor can control the hook knife to retract.

Optionally, the state of the hook knife may be determined according to a hook knife signal received by the hook knife motor. For example, the embroidery device may send a hook knife opening signal to the hook knife motor, and the hook knife motor controls the hook knife to open when receiving the hook knife opening signal; the embroidery equipment can send a hooking cutter back hooking signal to the hooking cutter motor, and when the hooking cutter motor receives the hooking cutter back hooking signal, the hooking cutter is controlled to hook back.

Optionally, the state of the hook knife may be determined according to a corresponding relationship between the working state of the hook knife and the rotation angle of the main shaft. For example, the corresponding relationship between the working state of the hook knife and the rotation angle of the main shaft may be: if the rotation angle of the main shaft is 150 degrees, the state of the hook knife at the moment can be determined to be the open state of the hook knife; if the rotation angle of the main shaft is 130 degrees, the state of the hook cutter at the moment can be determined as the hook cutter returning hook.

The state of the scissors can be that the scissors are opened or the scissors are cut back. For example, if the scissors are in the state of being opened, the scissors motor can control the moving blades in the scissors to move, so that the scissors are opened; if the scissors are in a state of being returned, the motor of the scissors can control the moving knife in the scissors to move, so that the scissors are returned.

Optionally, the state of the scissors may be determined according to a scissors signal received by the scissors motor. For example, the embroidery device may send a scissor opening signal to the scissor motor, and the scissor motor controls the scissor opening when receiving the scissor opening signal; the embroidery equipment can send a signal of the back cutting of the scissors to the scissors motor, and the scissors motor controls the back cutting of the scissors when receiving the signal of the back cutting of the scissors.

Optionally, the state of the scissors can be determined according to the corresponding relationship between the working state of the scissors and the rotation angle of the main shaft. For example, the corresponding relationship between the working state of the scissors and the rotation angle of the main shaft can be as follows: when the rotation angle of the main shaft is 100-150 degrees, the scissors are opened, when the rotation angle of the main shaft is 200-240 degrees, the scissors are cut back, and if the rotation angle of the main shaft is 70 degrees, the state of the scissors at the moment can be determined as the scissors are opened; if the rotation angle of the main shaft is 230 degrees, the state of the scissors at the moment can be determined as the scissors return.

Optionally, when the moving blade of the scissors moves to the position with the maximum cutting range, if the motor of the scissors does not receive a signal of the knife return of the scissors, the moving blade stops at the position with the maximum cutting range.

And S502, controlling the surface clamp and the embroidery frame according to the state of the hook knife and the state of the scissors.

The noodle clamp is used for clamping the noodle line. For example, the upper thread of the embroidery machine can be clamped by the upper clamp when the upper clamp is sucked, and the upper thread of the embroidery machine can be released by the upper clamp when the upper clamp is opened. Optionally, the control surface clamp can be closed or opened according to the electromagnet of the surface clamp. For example, the surface clamp is closed when the electromagnet of the surface clamp is energized in the forward direction, and the surface clamp is opened when the electromagnet of the surface clamp is energized in the reverse direction. Optionally, when the embroidery device receives a signal of closing the surface clamp, the electromagnet of the surface clamp can be energized in the forward direction, and when the embroidery device receives a signal of opening the surface clamp, the electromagnet of the surface clamp can be energized in the reverse direction.

The embroidery frame is used for fixing an embroidered object. For example, a cloth may be fixed in an embroidery frame, and an embroidery machine may embroider on the cloth in the embroidery frame. Optionally, the embroidery frame can move on a horizontal plane to facilitate embroidery by the embroidery machine. For example, on a coordinate axis with the embroidery machine as the origin, the embroidery frame may be moved in the X direction by a stepping motor in the X axis direction, or may be moved in the Y direction by a stepping motor in the Y axis direction. For example, the embroidery device sends an embroidery frame moving signal to a stepping motor in the X-axis direction, and the stepping motor in the X-axis direction can control the embroidery frame to move in the X-axis direction; the embroidery equipment sends an embroidery frame moving signal to the stepping motor in the Y-axis direction, and the stepping motor in the Y-axis direction can control the embroidery frame to move in the Y direction.

According to the state of the hook knife and the state of the scissors, the control surface clamp and the embroidery frame have the following two conditions:

case 1: according to the state of the hook knife, the control surface clamp and the embroidery frame.

When the hooked knife is in a state that the hooked knife is opened, the control surface clamp can clamp the facial suture and control the embroidery frame to move towards the first direction, so that the facial suture is tightened. Wherein the first direction is a direction in which the face line can be stretched. For example, if the embroidery frame can tighten the facial line when moving to the X direction, the first direction is the X direction; if the upper thread can be tightened when the embroidery frame moves to the Y direction, the first direction is the Y direction.

Optionally, when the hook knife is opened to the lower side of the upper thread, the control surface clamp can clamp the upper thread and control the embroidery frame to move towards the first direction. For example, when the hook knife is opened to a position below the upper thread, the embroidery device controls the surface clamp to clamp the upper thread and controls the embroidery frame to move in the first direction, and the upper thread can be tightened when the embroidery frame moves because the surface clamp already clamps the upper thread.

Optionally, whether the hook knife is opened to the lower part of the upper thread can be determined according to the rotation angle of the main shaft. For example, if the hook blade is aligned with the upper thread when the main shaft rotates to 150 degrees, the embroidery apparatus may determine that the hook blade is opened to a position below the upper thread when the rotation angle of the main shaft is greater than 150 degrees.

Optionally, the surface clamp and the tabouret may be controlled according to the length of time the hook knife is opened. For example, after the hook knife is opened for a first preset time, it may be determined that the hook knife is opened to a position below the upper thread, and at this time, the embroidery device may control the surface clamp to clamp the upper thread and control the embroidery frame to move in the first direction.

When the hooking knife is in a state of hooking back, the control surface clamp is opened, so that the hooking knife can hook the facial line. For example, when the hook knife hooks back, the hook knife can hook the upper thread, so that the upper thread is required to be released by the surface clamp, and the hook knife can drive the upper thread to move towards the direction of hooking back of the hook knife.

Optionally, the control surface clamp can be opened according to the time length of the hook knife hooking. For example, after the hook blade hooks back for the second preset time, the embroidery device may control the surface clamp to open the upper thread, so that the hook blade may drive the upper thread to move toward the hook blade.

Alternatively, the control surface clamp may be opened depending on the angle of rotation of the spindle. For example, when the main shaft rotates to a first preset angle, the embroidery device can control the surface clamp to open the upper thread, so that the hook knife can drive the upper thread to move towards the hooking direction of the hook knife.

Under the condition, when the state of the hook knife is opened for the hook knife, the embroidery device can control the surface clamp to clamp the facial line, and control the embroidery frame to move towards the first direction, so that the facial line is tightened, when the hook knife hooks back, the hook knife can accurately hook the facial line, the unhooking rate of the facial line is reduced, and when the hook knife hooks the facial line, the control surface clamp of the embroidery device is opened, so that the hook knife can hook the facial line by a preset length, when the scissors cut the line, the accuracy rate of cutting the line by the embroidery device can be improved, and the line cutting effect of the embroidery device can be further improved.

Case 2: control surface clips and an embroidery frame according to the state of the scissors.

Optionally, when the scissors are in the state of being retracted, the control surface clamp can clamp the facial suture, and the embroidery frame is controlled to move towards the second direction, so that the facial suture is loosened. Wherein the second direction is a direction in which the face line can be relaxed. For example, if the upper thread can be loosened when the embroidery frame moves towards the X direction, the second direction is the X direction; if the upper thread can be loosened when the embroidery frame moves towards the Y direction, the second direction is the Y direction.

Optionally, the surface clips and the tabouret can be controlled according to the time length of the scissors for cutting back. For example, after the scissors are cut back for a third preset time, the embroidery device may control the surface clamp to clamp the upper thread and control the embroidery frame to move towards the second direction, so that the upper thread is released.

Optionally, the surface clamp and the embroidery frame can be controlled according to the rotation angle of the main shaft. For example, when the main shaft rotates to a second preset angle, the embroidery device may control the surface clamp to clamp the upper thread and control the embroidery frame to move to a second direction, so that the upper thread is released.

Under the circumstances, when the scissors are in a scissors return state, the embroidery device can control the surface clamp to clamp the upper thread and control the embroidery frame to move towards the second direction, so that the upper thread is loosened, the accuracy of thread cutting can be improved when the scissors cut the thread, and meanwhile, after the thread cutting is finished, the hook knife needs to hook the upper thread out of the fabric, so that the surface clamp clamps the upper thread, and the hook knife can be prevented from hooking the embroidery thread in the needle head (for example, the friction force of the fabric is large, so that when the cut upper thread is difficult to hook out, if the surface clamp does not clamp the upper thread, the hook knife can hook the embroidery thread in the needle head), and further the effect of the embroidery device in the thread cutting process is improved.

The embroidery apparatus may further include a detection device. Wherein, detection device is used for detecting whether the position of scissors is correct. For example, the detection means may be an optoelectronic switch. Optionally, in the process that the scissors are opened to the maximum position or the scissors return to the initial position, if the position detection device does not send an in-place signal, the scissors are controlled to stop moving, and fault information is generated. The maximum position is the position where the movable knife moves when the range of the opening of the scissors is maximum, and the initial position is the position where the movable knife moves when the scissors are closed. For example, in the process that the movable knife of the scissors moves to the maximum position, if the detection device does not detect that the movable knife moves to the maximum position, the embroidery device controls the scissors to stop moving and generates fault information that the opening of the scissors is not in place; in the moving process of the initial position of the moving knife of the scissors, if the detection device does not detect that the moving knife moves to the initial position, the embroidery device controls the scissors to stop moving and generates fault information that the back knife of the scissors is not in place.

If the position detection device sends out an in-place signal, the scissors are controlled to move to the maximum position or the initial position. For example, in the process that the movable knife of the scissors moves to the maximum position, if the detection device detects that the movable knife moves to the maximum position, the embroidery device controls the movable knife to move to the maximum position; when the moving blade of the scissors moves to the initial position, if the detection device detects that the moving blade moves to the initial position, the embroidery device controls the moving blade to move to the initial position.

Optionally, the detection device may be disposed between the initial position and the maximum position, and the detection device may also be disposed between the initial position and the maximum position, which is not limited in this embodiment of the application.

Optionally, the detection device may detect whether the position of the hook knife is correct. For example, when the detection device sends an in-place signal, the position of the hook knife can be determined to be correct, and when the detection device does not send the in-place signal, the position of the hook knife can be determined to be incorrect, the embroidery device controls the hook knife to stop moving, and fault information that the hook knife is not in place is generated.

The embodiment of the application provides a thread cutting control method of embroidery equipment, acquires the state of a hook switch and the state of scissors, and when the state of the hook switch is that the hook switch is opened, the control surface clamp clamps the facial thread, and controls the tabouret to move to the first direction, so that the facial thread is tightened, and when the state of the hook switch is that the hook switch is hooked back, the control surface clamp is opened, so that the hook switch can hook the facial thread. When the scissors are in the state of cutting back, the control surface clamp clamps the facial suture and controls the embroidery frame to move towards the second direction, so that the facial suture is loosened. In the method, when the hook knife hooks back, the upper thread is tightened, so that the hook knife can accurately hook the upper thread, the unhooking rate of the upper thread is reduced, and when the hook knife hooks the upper thread, the control surface clamp of the embroidery device is opened, so that the hook knife can hook the upper thread by a preset length.

On the basis of any of the above embodiments, the following describes in detail the process of thread cutting control of the embroidery apparatus by a specific example with reference to fig. 6.

Fig. 6 is a schematic process diagram of thread trimming control of an embroidery device according to an embodiment of the present application. Please refer to fig. 6, which includes the rotation angle of the main shaft, the scissors, the hook, the thread-fastening fork, the surface clamp and the embroidery frame. The main shaft rotation angle is based on 100 degrees (the initial position of the main shaft corresponds to 100 degrees of the main shaft rotation scale). The difference between the first rotating angle and the second rotating angle is 360 degrees, the difference between the second rotating angle and the third rotating angle is 360 degrees, and the main shaft cuts lines in the process of rotating for two circles.

Referring to fig. 6, the embroidering apparatus controls the scissors, the hook and the thread take-up fork according to the rotation angle of the main shaft, and controls the surface clamp and the embroidery frame according to the state of the hook and the state of the scissors. When the main shaft rotates to 120 degrees of the first circle, the thread is buckled by the thread-buckling fork, when the main shaft rotates to 200 degrees of the first circle, the hook knife is opened, when the main shaft rotates to 290 degrees of the first circle, the scissors are opened, when the hook knife is opened, the control surface clamp of the embroidery device is attracted to clamp the upper thread, and the embroidery frame is controlled to be pulled out, so that the upper thread is stretched. Therefore, the upper thread can be hooked by the hooking knife accurately, and the unhooking rate of the upper thread is reduced.

Referring to fig. 6, when the hook blade is hooked back, the control surface clamp of the embroidery device is opened, so that the hook blade can hook up the upper thread. And when the main shaft rotates to 220 degrees of the second weight, the thread hooking cutter stops hooking the thread. And when the main shaft rotates to 30 degrees of the second circle, the scissors return. In the process of returning the scissors, the control surface clamp of the embroidery device is sucked to clamp the upper thread and control the embroidery frame to withdraw, so that the upper thread is loosened, and the accuracy of the scissors in thread cutting can be improved. When the main shaft rotates to 60 degrees of the second circle, the thread buckling fork is opened, when the main shaft rotates to 80 degrees of the second circle, the embroidery thread is cut off by the scissors, the hook knife is controlled to be opened by the embroidery equipment, and the cut-off upper thread is hooked. Therefore, the embroidery thread in the needle head can be prevented from being hooked by the hook knife, and the thread cutting effect of the embroidery equipment can be improved.
