[0060] It should be noted that the user information (including but not limited to user device information, user personal information, etc.) and data (including but not limited to data used for analysis, stored data, displayed data, etc.) involved in this application are all information and data authorized by the user or fully authorized by all parties, and the collection, use and processing of relevant data must comply with the relevant laws, regulations and standards of the relevant countries and regions, and provide corresponding operation entrances for users to choose to authorize or refuse.

[0061] In the embroidery machine, the upper thread is also called the upper thread, which refers to the thread passing through the embroidery machine head. After the embroidery machine sews, the main body of the upper thread is on the front side of the fabric, and the thread end of the upper thread is on the back side of the fabric; the lower thread is also called the lower thread, which refers to the thread inside the embroidery machine shuttle. A shuttle case will be installed in the embroidery machine shuttle, and the bobbin core in the shuttle case is wound around the lower thread. After the embroidery machine sews, the lower thread is on the back side of the fabric, and the thread end of the lower thread is on the back side of the fabric; the shuttle includes horizontal shuttle and vertical shuttle, which mainly cooperates with the needle and thread to form a lock stitch; the shuttle case is a component that holds the shuttle thread and is fixed in the shuttle system of the embroidery machine.

[0062] Thread cutting of an embroidery machine means that when a part of a pattern is embroidered or a certain color of thread is embroidered, the bottom thread and the top thread need to be cut off to facilitate subsequent embroidery work; after thread cutting, the top thread end is held on the machine head, and the bottom thread end is held near the rotary shuttle; when embroidering after thread cutting, the top thread and the bottom thread ends will be re-knotted through the action of the machine needle and the rotary lock to achieve normal sewing; in embroidery machine embroidery operation, the number of the first stitch usually refers to the cycle process of the needle tip first dropping the needle into the cloth and stepping out.

[0063] The upper thread ends of the embroidery machine refer to the excess thread ends that appear on the upper thread when the embroidery machine starts embroidery operation; usually caused by not cutting the thread ends before changing the thread or starting the machine, the thickness of the upper thread does not match the needle eye, etc.; these thread ends may cause problems such as thread breakage and skipped stitches during the embroidery process.

[0064] For the processing of the upper thread ends of the embroidery machine, mechanical adjustment method, manual processing method, automatic processing method and other methods are usually used to realize the processing of the upper thread ends of the embroidery machine. The appropriate method is mainly selected according to the requirements of the embroidery work, the performance of the embroidery machine and other factors.

[0065] As long as the machine allows, embroidery machines will be equipped with upper thread clamping devices. That is, in the commonly used embroidery machine needle-starting upper thread processing process, the upper thread clamping device is mainly used to control the surface clamping action to ensure that the embroidery machine needle-starting upper thread does not come off during the needle-starting process.

[0066] The upper thread clamping device controls the upper clamping action to cut off the upper thread end of the embroidery machine needle, including: when the embroidery machine starts embroidery after cutting the thread, the upper clamp performs an opening and a closing action for each needle of the embroidery.

[0067] After using the upper thread clamping device to control the surface clamping action to ensure that the thread does not come off when the needle is started, it cannot improve the problem of the thread ends on the back of the fabric being too long. Instead, it will lengthen the length of the upper thread ends, affecting the beauty of the embroidery.

[0068] In view of the above problems, the present application provides a method for controlling the thread ends of the needle-starting surface thread of an embroidery machine, which obtains the rotation angle of the main shaft of the embroidery machine in real time, and switches the operation state of the surface thread clamping device based on the rotation angle. Since the surface clamping device moves three times in the first needle of embroidery at the preset main shaft angle, the thread end length problem at the needle-starting position on the reverse side of the fabric is greatly improved, and the aesthetics of the embroidery is greatly improved.

[0069] Figure 1 The process of a method for controlling the needle thread of an embroidery machine provided in this embodiment is as follows: Figure 1 .like Figure 1 As shown, the present embodiment provides a method for controlling the needle thread of an embroidery machine, comprising:

[0070] S101, obtaining the rotation angle of the main shaft of the embroidery machine in real time.

[0071] Among them, the embroidery machine is an automated equipment used for embroidery on fabrics. It uses a control system to convert the designed pattern into machine-recognizable instructions, and realizes the embroidery operation by driving various mechanical parts such as needle bars, rotary shuttles, thread take-up rods, etc.; embroidery machines are widely used in garment embroidery and processing, decorations, household items and fabric processing.

[0072] The spindle of an embroidery machine is usually composed of a spindle motor, a transmission mechanism, a spindle body, and related sensors and controllers, which control the various actions of the embroidery machine during the embroidery process. The rotation angle of the embroidery machine spindle refers to the angle that the spindle rotates relative to a certain initial position during the embroidery process. This angle is usually measured and represented by a code disk or sensor connected to the spindle, and is used to accurately control the operation of the embroidery machine.

[0073] During the operation of the embroidery machine, the spindle rotates 360 degrees for each rotation and each stitch. When the embroidery machine is stopped, if the spindle stops at the position with a scale of 100 degrees, that is, each component of the embroidery machine takes 100 degrees as the reference point, the spindle rotates at different angles of 0-360 degrees to complete its respective actions, so that the embroidery machine system can operate normally.

[0074] In this step, the rotation angle of the embroidery machine main shaft can be obtained in real time, for example, by using a sensor, motor feedback, a transformer, etc., and the rotation angle of the embroidery machine main shaft obtained in real time is transmitted to the control system.

[0075] S102. When the embroidery machine enters the first stitch of the embroidery program after thread trimming, the operating state of the surface thread clamping device is switched based on the rotation angle to control the passing state of the surface thread of the embroidery machine relative to the corresponding thread hole.

[0076] Wherein, the upper thread clamping device is in a suction state before entering the thread cutting and embroidery program.

[0077] The thread cutting and embroidery starting procedures of the embroidery machine are two operating steps in the automated embroidery process, which are used to ensure the continuity and quality of embroidery.

[0078] In this step, the thread trimming program of the embroidery machine includes needle locking, thread trimming and thread end processing; the embroidery starting program includes debugging, determining the embroidery starting point, and the start and continuous process of embroidery.

[0079] The upper thread clamping device is a key component in the embroidery machine. It fixes the upper thread on the fabric through a series of clamping parts and controls the position of the pressure block through an elastic clamping structure to clamp the upper thread. It also manages and controls the tension and position of the upper thread during the embroidery process to achieve high-quality embroidery effects.

[0080] The upper thread clamping device has two states: an open state and a closed state. When the upper thread is in the open state, the upper thread can pass through the thread hole, and when the upper thread is in the closed state, the upper thread is firmly clamped.

[0081] It can be understood that, based on the rotation angle, switching the operating state of the surface thread clamping device is to control the operating state of the surface thread clamping device by obtaining the rotation angle of the embroidery machine main shaft in real time; different operating states of the surface thread clamping device correspond to different passing states of the thread hole.

[0082] In a possible implementation, based on the rotation angle, switching the operating state of the thread clamping device can be implemented in the following manner, the method comprising:

[0083] A suitable sensor is selected to obtain the rotation angle of the main shaft in real time, wherein the sensor can accurately record the rotation angle of the main shaft and transmit the recorded rotation angle of the main shaft to a corresponding control system.

[0084] In this step, the sensor type may be a photoelectric sensor, a Hall effect sensor, etc., without limitation.

[0085] The sensor, control system, and face thread clamping device are connected to ensure that the control system can read the rotation angle of the main shaft in real time. The control system triggers the face thread clamping device to a corresponding state at a specific angle based on the read rotation angle.

[0086] In this step, the design of the control system includes data reading, event triggering, and command transmission. Among them, data reading is to read the data uploaded by the sensor in real time; event triggering is used to generate control instructions that trigger corresponding events at a specific spindle rotation angle; command transmission is to transmit the control instructions generated by the control system to the surface thread clamping device to control the surface thread clamping device to achieve the transformation of the operating state.

[0087] The method for controlling the thread ends of the upper thread of the embroidery machine provided in this embodiment obtains the rotation angle of the main shaft of the embroidery machine in real time; when the embroidery machine enters the first needle of the embroidery program after thread trimming, the operation state of the upper thread clamping device is switched based on the rotation angle to control the passing state of the upper thread of the embroidery machine relative to the corresponding thread hole. The method effectively reduces the length of the upper thread ends on the reverse side of the fabric at the needle starting position, and improves the beauty of the embroidery product.

[0088] Figure 2 The process of a method for controlling the needle thread of an embroidery machine provided in this embodiment is as follows: Figure 2 In this embodiment, the operating states of the upper thread clamping device include: an open state and a closed state. Figure 1 Based on the embodiment, the operation state switching process of the thread clamping device is explained. Figure 2 As shown, the method includes:

[0089] S201. After the embroidery machine is powered on, the upper thread clamping device is reset.

[0090] Among them, resetting the upper thread clamping device is to restore the embroidery machine to the state when the power was last turned off, ensuring that the upper thread clamping device is in a correct initial state, that is, restored to a known initial state, so as to perform stable embroidery operations subsequently.

[0091] In this step, the upper thread clamping device may be reset by, for example, power-on initialization, resetting state information of the upper thread clamping device, executing the reset process, and confirming the state after the reset process.

[0092] In a possible implementation, resetting the upper thread clamping device may be performed in the following manner, the method comprising:

[0093] Controlling the upper thread clamping device to enter an open state, and after a preset time, controlling the upper thread clamping device to switch from the open state to a closed state;

[0094] Among them, when the embroidery machine starts to embroider or needs to adjust the upper thread, the control system will issue a command to drive the driving rod to move, so that the pressure block is separated from the upper thread clamping seat, thereby opening the upper thread clamping device, so that the upper thread clamping device enters the open state; after opening the upper thread clamping device, the preset time length is usually determined according to the requirements of the embroidery process and the performance of the embroidery machine to ensure that the upper thread can be clamped in time when needed; after the preset time length is reached, the control system issues a command to drive the driving rod to move in the opposite direction, so that the pressure block is tightly combined with the upper thread clamping seat, so that the upper thread clamping device is converted to the suction state.

[0095] Determining the status information of the upper thread clamping device when the embroidery machine was last powered off;

[0096] The state information of the embroidery machine when it was powered off last time refers to the working state and related settings saved by the upper thread clamping device when the power was last turned off.

[0097] In this step, the status information of the upper thread clamping device mainly includes but is not limited to the clamping status and position information of the upper thread clamping device.

[0098] In a possible implementation, determining the state information of the upper thread clamping device when the embroidery machine was last powered off can be achieved in the following manner, the method comprising:

[0099] Using the control system to monitor the state changes of the upper thread clamping device during the operation of the embroidery machine;

[0100] When the embroidery machine is powered off, the control system saves the current state information of the upper thread clamping device into the memory;

[0101] The embroidery machine can determine the state of the upper thread clamping device when the power was last turned off by comparing the current state with the stored state information.

[0102] When the head of the embroidery machine is started, the upper thread clamping device is reset based on the status information.

[0103] In a possible implementation, based on the state information, resetting the upper thread clamping device can be implemented in the following manner, the method comprising:

[0104] The control system reads the status information of the upper thread clamping device when the embroidery machine was powered off last time, and sends a driving instruction to drive the pressing block, driving rod and other components of the upper thread clamping device to act, thereby realizing the reset process;

[0105] During the resetting process, the control system records the information of the upper thread clamping device in real time, and after the resetting process is completed, confirms the state after the resetting process.

[0106] S202: Acquire the rotation angle of the main shaft of the embroidery machine in real time.

[0107] Among them, step S202 is similar to the above step S101 and will not be repeated here.

[0108] S203, when the embroidery machine enters the first stitch of the embroidery program after thread trimming, determine whether the rotation angle reaches a first preset angle; if so, execute step S204; if not, return to step S203.

[0109] Wherein, when the embroidery machine enters the first stitch of the embroidery program after thread cutting, the main axis of the embroidery machine is at a reference angle, and the reference angle is a preset angle; the reference angle is smaller than the rotation angle; and the first preset angle is larger than the reference angle.

[0110] In this step, the first preset angle may be set to an angle between 110° and 130°, for example.

[0111] In a possible implementation, in the first stitch of embroidery, the initial reference angle of the main axis can be Figure 3The first preset angle can be 100°. Figure 3 The setting is 120°.

[0112] S204, controlling the upper thread clamping device to switch from a closed state to an open state.

[0113] The upper thread clamping device is controlled by the control system to switch from the closed state to the open state, that is, it is achieved by transmitting corresponding control instructions through the control system.

[0114] S205, determining whether the rotation angle reaches a second preset angle, if so, executing step S206; if not, returning to step S204.

[0115] The second preset angle is greater than the first preset angle.

[0116] In this step, the second preset angle may be set to an angle between 180° and 200°, for example.

[0117] In a possible implementation, the second preset angle may be Figure 3 190° set in.

[0118] S206, controlling the upper thread clamping device to switch from the open state to the closed state.

[0119] Among them, step S206 is similar to the above step S204 and will not be repeated here.

[0120] S207, determining whether the rotation angle reaches a third preset angle; if so, executing step S208; if not, returning to step S207.

[0121] The third preset angle is greater than the second preset angle, and the first preset angle, the second preset angle and the third preset angle are in the same rotation period of the main shaft.

[0122] In this step, the third preset angle may be set to an angle between 290° and 310°, for example.

[0123] In a possible implementation, the third preset angle may be Figure 3 The setting is 300°.

[0124] S208, controlling the upper thread clamping device to switch from the closed state to the open state.

[0125] Among them, step S208 is similar to the above step S204 and will not be repeated here.

[0126] The present embodiment provides a method for controlling the thread ends of the needle-starting upper thread of an embroidery machine. After the embroidery machine is powered on, the upper thread clamping device is reset; the rotation angle of the main shaft of the embroidery machine is obtained in real time; it is determined whether the rotation angle reaches a first preset angle; when the rotation angle reaches the first preset angle, the upper thread clamping device is controlled to switch from an aspirated state to an open state; it is determined whether the rotation angle reaches a second preset angle; when the rotation angle reaches the second preset angle, the upper thread clamping device is controlled to switch from an open state back to an aspirated state; it is determined whether the rotation angle reaches a third preset angle; when the rotation angle reaches the third preset angle, the upper thread clamping device is controlled to switch from an aspirated state to an open state. This method greatly improves the thread end length problem at the needle-starting position on the reverse side of the fabric without increasing the problem of thread derailment, and does not increase the physical cost of the embroidery machine.
