It should be understood that the control device may be a single chip, a personal computer PC, a tablet or other terminal device with processor function.
The spindle motor 13 and the take-up lever motor 14 are controlled by a single chip microcomputer and are connected with the mechanical device 12. The spindle motor rotates according to an instruction sent by the control device to drive the mechanical device to move; the take-up lever motor is matched with the spindle motor to rotate according to the setting of the control device, and drives the take-up lever in the mechanical device to move.

Specifically, the take-up lever motor is matched with the main shaft motor to rotate according to the instruction, and meanwhile, the swing link shaft drives the take-up lever to move, and the take-up lever swing link drives the take-up lever to move so as to realize the take-up movement.
FIG. 5 is a schematic flow chart of a first embodiment of a method for controlling a thread take-up lever of a sewing machine according to an embodiment of the present invention. As shown in fig. 5, the method comprises the steps of:
s101: and obtaining the thickness of the cloth to be sewn.
This scheme is provided with different take-up lever heights to the thickness of different cloth to make better effect to the cloth of different thickness. Then, the thickness of the cloth to be sewn should be obtained first.
There are various ways to obtain the thickness of the cloth to be sewn, which may be the cloth thickness inputted by the user, or the cloth thickness detected by a sensor connected to the sewing machine, or the cloth thickness detected by reading an external device.
Specifically, the sensor connected to the sewing machine may be disposed on the sewing machine, for example, on a needle bar of a mechanical device of the sewing machine, or may be disposed on a table top edge of the sewing machine (the table top of the sewing machine refers to a table top on which a cloth to be sewn is disposed), and the sensor may be specifically an infrared sensor, a laser sensor, a radar sensor, or the like, which is not required in this scheme.
S102: a first correspondence corresponding to the thickness is obtained.
According to the obtained thickness of the cloth to be sewn, the control device searches a first corresponding relation which is configured in advance and corresponds to the thickness or the thickness range of the thickness through a traversing or comparing method, and the first corresponding relation is used for representing the corresponding relation between the angle of a spindle motor of the sewing machine and the height of a thread take-up lever. It will be understood by those skilled in the art that the spindle motor angle is the same as the rotation angle of the sewing machine spindle, i.e., the first correspondence is also used to indicate the correspondence between the rotation angle of the sewing machine spindle and the thread take-up lever height.
S103: and controlling the height of a take-up lever of the sewing machine according to the first corresponding relation in the sewing process of the cloth to be sewn.
In this step, the control device controls the height of the thread take-up lever of the sewing machine according to the acquired first relationship corresponding to the thickness of the cloth to be sewn, the first relationship representing the correspondence between the angle of the spindle motor of the sewing machine and the height of the thread take-up lever. The control device controls the spindle motor to drive the mechanical device to move, and simultaneously controls the take-up lever motor to rotate according to the angle of the spindle motor so as to achieve the height of the take-up lever corresponding to the angle of the spindle motor in the first corresponding relation.
The control method of the take-up lever of the sewing machine provided by the embodiment acquires the first corresponding relation corresponding to the thickness by acquiring the thickness of the cloth to be sewn, controls the height of the take-up lever of the sewing machine according to the first corresponding relation in the sewing process of the cloth to be sewn, realizes setting different heights of the take-up lever of the sewing machine for the cloth with different thicknesses, further enables the sewing machine to have better tension of the control line in the sewing process of the cloth with different thicknesses and materials, and improves the sewing effect.
In the present embodiment, each thickness or each thickness range corresponds to a corresponding relationship between a spindle motor angle and a thread take-up lever height of a different sewing machine, and a corresponding relationship between a spindle motor angle and a thread take-up lever height of a sewing machine corresponding to different thickness ranges configured in advance will be described below by using a specific embodiment.
In practical applications, the relationship between the take-up lever motor angle and the take-up lever height is fixed, so the relationship between the take-up lever height and the spindle motor angle needs to be configured in advance according to the thickness of the cloth to be sewn. The control device determines the rotation angle of the take-up lever motor corresponding to the rotation angle of the spindle motor according to the preset corresponding relationship between the rotation angle of the spindle motor and the rotation angle of the take-up lever motor, so that the take-up lever can rotate according to the acquired rotation angle of the take-up lever motor, the take-up lever can move according to the preset corresponding relationship, and the specific corresponding relationship can be represented by a curve.
For example, according to the thickness range of the material to be sewn, three different corresponding relations between the rotation angle of the spindle motor and the height of the thread take-up lever are configured, see fig. 6. When the thickness of the material to be sewn is larger than 1.5mm and smaller than 2.5mm, the relation between the height of the take-up lever and the angle of the spindle motor is shown as a curve 1, when the angle of the spindle motor is 0 degree, the height of the take-up lever is 39.5mm, and when the angle of the spindle motor is 70 degrees, the height of the take-up lever reaches the maximum 73.4mm, so that a proper take-up effect is obtained; when the thickness of the material to be sewn is less than or equal to 1mm, the relation between the height of the thread take-up lever and the angle of the spindle motor is shown as a curve 2, when the rotation angle of the spindle motor is 0 degrees, the height of the thread take-up lever is 58.3mm, when the angle of the spindle motor is 50 degrees, the height of the thread take-up lever reaches the highest 73.4mm, the thread is taken up earlier, and the proper loosening take-up effect is obtained; when the thickness of a material to be sewn is larger than or equal to 3mm, tighter take-up is needed, the relation between the height of the take-up lever and the angle of the spindle motor is shown as a curve 3, when the rotation angle of the spindle motor is 0 degrees, the height of the take-up lever is 17mm, when the angle of the spindle motor is 90 degrees, the height of the take-up lever reaches the highest 73.4mm, and tighter take-up is achieved later; the curve can be finely adjusted according to the actual material thickness and the actual take-up effect, and curves in different shapes can be applied to adapt to more materials and material thicknesses.
FIG. 7 is a flowchart illustrating a second embodiment of a method for controlling a thread take-up lever of a sewing machine according to an embodiment of the present invention. As shown in fig. 7, the method for obtaining the first corresponding relationship corresponding to the thickness specifically includes the following steps:
