Problems solved by technology
At present, the initial positioning sensors used in stepper motor drive include photoelectric sensors and magnetoelectric switch sensors. Photoelectric sensors are prone to failure due to environmental factors such as dust.
The magnetic switch type is easily affected by the material of the sensor object, which affects the consistency of positioning accuracy during mass production.

The invention relates to a sewing machine positioning method, computer equipment and a sewing machine. According to a positional relationship between a reference mark arranged on a to-be-detected component and a fixed mark arranged on the sewing machine, the position of the to-be-detected component is judged; when the positional relationship between the reference mark and the fixed mark satisfiesa preset condition, the to-be-detected component is located at an initial position, and a first signal correspondingly triggered by the to-be-detected component at the initial position is obtained; when the positional relationship between the reference mark and the fixed mark does not satisfy the preset condition, the position of the to-be-detected component is adjusted until the preset conditionis satisfied to make the to-be-detected component located at the initial position, and the first signal correspondingly triggered by the to-be-detected component at the initial position is obtained. According to the first signal, the to-be-detected component is accurately reset from a starting position to the initial position. Moreover, the sensor used for obtaining a position signal of the to-be-detected component is a Hall sensor, so that the sewing machine is not affected by an external environment in the positioning process.
Description
technical field [0001] The present application relates to the technical field of sewing machines, in particular to a sewing machine positioning method, computer equipment and a sewing machine. Background technique [0002] As the degree of automation of sewing machines becomes higher and higher, more and more institutions are driven by stepping motors. In general, when a stepper motor is driven, a sensor is required for initial positioning. At present, the initial positioning sensors used in the stepper motor drive include photoelectric sensors and magnetoelectric switch sensors. Photoelectric sensors are prone to failure due to environmental factors such as dust. The magnetoelectric switch type is easily affected by the material of the sensor object, which affects the consistency of positioning accuracy during mass production. Contents of the invention [0003] Based on this, it is necessary to address the above-mentioned technical problems and provide a sewing machine ...
