Description

Circuit board scaling method

The invention relates to a method for classifying a circuit board expansion and contraction, which mainly relates to a technical field for classifying a shrinkage phenomenon caused by a circuit board through a process.

Conventional printed circuit boards in the process, after pressing, often due to temperature, pressure, humidity, glass fiber and press machine precision and other issues, resulting in a slight increase in the printed circuit board, so a number of printed circuit boards It must be classified according to the different state of its expansion and contraction. Generally, the industry will divide the expansion and contraction value into three or more types, and then provide it to the press machine of the pre-process, or the drilling machine and exposure machine of the post-process, as Subsequent basis for adjustment.

The traditional method for classifying the board's ups and downs is to set up a moving mechanism to classify the board according to the received category judgment signals, and then transport the plurality of boards in different areas to other process operations separately. Because the classification is only based on the location partition, it is not marked on each circuit board, which is not only not conducive to machine interpretation or recording, but also often causes mixing due to job loss, and even leads to the subsequent failure to determine the category.

In view of this, the inventor can use the research to create a cost case. The proposal of this case is to improve the shortcomings of the existing classifications, and to make the classification method more perfect, ideal and practical. The inventor has completed the invention according to the accumulated experience of decades of experience in the industry, the application and experience of many domestic and foreign patents, and the efforts to solve the problem. The inventor hopes that with the proposal of this case, he will be able to contribute his own talents to the industry.

In order to improve the classification of the conventional circuit board, it is easy to discriminate due to the mixing, and the machine can not record and read. The main purpose of the present invention is to provide an innovative circuit board classification method, which is directly drilled. According to the expansion and contraction image, the drilling is performed at different positions, and then according to the position or the hole distance of the drilling hole, the classification of the expansion and contraction can be known; thereby, the classification placement can be provided to achieve the classification purpose. The advantage is that even if it is inadvertently mixed, the classification can be obtained by reading, and further, the tool reading function can be used to record and manage the expansion and contraction status.

In order to achieve the above object, the specific content of the present invention is as follows: the step process includes: reading an exposure target, interpreting the exposure target, defining a classification of the expansion and contraction, drilling the target hole, classifying the target hole according to the classification, and reading the target hole and The target holes are classified and the spacing is calculated and classified according to the spacing.

The read exposure target is read by a reading device, such as an X-RAY, on an exposed target position on the circuit board.

The reading the exposure target and defining the classification of the expansion and contraction according to the position of the exposure target, and collecting a certain number or a predetermined classification range, for example, the exposure target position data of five hundred circuit boards, is calculated and calculated. The classification of the increase and decrease.

The drill positioning target hole is tied to a set position on the circuit board to drill one or more positioning target holes by the drilling target machine.

The classification target hole is classified according to the classification, and the classification target hole is drilled by the drilling target machine according to the classification of the expansion and contraction on the circuit board.

The reading locates the target hole and classifies the target hole and calculates the spacing, and reads the distance between the positioning target hole and the sorting target hole by a reading device, such as a CCD, and performs calculation.

The sorting is performed according to the interval, and after the classification of the circuit board is known, it is moved or placed to a designated classification by an automated device such as a robot arm.

The advantage of this case is that the use of this case can effectively improve the classification efficiency, especially because the physical mark is formed on the circuit board, even if it is accidentally mixed, the classification of the expansion and contraction can be obtained by reading, and the data can also provide the expansion and contraction. Recording and management of the situation; in addition, it can also improve the automation of the production line and save manpower.
