Description

Quantitative working structure per unit length

This creation is about a unit-length quantitative working structure, especially that it can control external equipment through the motion control unit, and read the value of the coordinate feedback device at a fixed time. The motion control unit can be used when the fixed movement distance of each axis Trigger external equipment (such as laser processing machine, tin wire supply equipment, glue supply equipment or testing equipment, etc.).

Laser processing machine is an advanced equipment for engraving materials that need to be engraved with laser. Laser engraving machines are different from mechanical engraving machines and other traditional manual engraving methods. Mechanical engraving machines use mechanical means, such as diamond, to engrave other things with extremely high hardness.

The laser processing machine uses laser thermal energy to engrave the material. The laser processing has a wider range of application, and has higher engraving accuracy and faster engraving speed. Compared with the traditional hand-carving method, laser engraving can also make the carving effect very delicate, which is no less than the level of hand-carving. Because laser processing machines have so many advantages, the application of laser processing machines has gradually replaced the traditional engraving equipment and methods, and has become the main processing equipment.

However, when the laser processing machine actually performs laser processing, it will have at least the following disadvantages:

Please refer to figure 6, several thick black dots in the figure represent the laser head processing the workpiece The processing point, the laser head can be driven by the drive mechanism and the control program to move according to the planned processing path and apply laser energy to the workpiece, but when the processing path reaches the circle shown in Figure 6 At the corner, the moving speed of the laser head will decrease, resulting in shortening the laser processing distance. From the circle drawing in Figure 6, we can find that the distance between the processing points at the corner is compared to other processing paths. The processing point 90 is significantly shortened, that is, the laser energy applied at the corner is more than other processing paths. In this way, the uneven laser processing point will not meet the processing requirements and affect the processing accuracy.

The tin wire supply equipment, glue supply equipment or testing equipment with the same working principle as the laser processing machine also have the wrong amount of solder wire or glue glue due to the movement speed (acceleration and deceleration) of the working head, or The problem of inaccurate detection position is therefore necessary for improvement.

Therefore, based on the concept of continuous research, improvement and innovation of the product, the creator has produced this creation based on many years of practical experience in the development of this product, and active and concentrated research and development, through countless practical design experiments.

The above is an introduction to the components and composition of the creation, and then the use characteristics and effects of the creation are introduced as follows:

Please refer to FIG. 1 and FIG. 2. In this embodiment, the external device 10 is used as a laser processing machine for illustration. The creation control steps are as follows:

1. The user inputs the working data parameter values of the platform 20 to the motion control unit 30 through the man-machine interface 60, such as the working movement path and processing movement speed of the X-axis unit 21, a Y-axis unit 22, and a Z-axis unit 23 , And input the processing distance and the reaction speed of the external device 10.

2. After the motion control unit 30 obtains the working data parameter values such as the work movement path, the processing movement speed, the processing distance, and the reaction speed of the external device input by the user, the calculation platform 20 has its X-axis unit 21, a Y-axis unit 22, and a Z The acceleration/deceleration values of the axis unit 23 on the X, Y, and Z axes.

The current coordinate reading method of each axis of the platform 20 will be different according to the transmission method of each axis of the platform 20. If the X-axis motor 211, the Y-axis motor 221, and the Z-axis motor 231 are selected from stepper motors, the coordinate is motion control. Unit 30 is calculated and it is read if it is selected from the servo motor The value of the encoder is known, if it is a linear motor, the value of the optical scale is known;
