Description

Technical Field

[0001] The present invention relates to a technical field of resin content detection, and more particularly to a resin content detection device and method thereof that uses a capacitive sensing device, a capacitive corresponding sensing device and a signal control processing module to sense a non-metallic object containing resin in a non-contact manner. Background Art

[0002] Printed circuit boards (PCBs) have a wide range of applications and play an important role in various fields. They are used in almost all fields such as communication products, transportation vehicles, electronic equipment, precision instruments and industrial products. With the introduction of new products, the demand for printed circuit boards remains high. In the global industrial chain, the PCB industry can be said to have a pivotal position.

[0003] As the basic material source of printed circuit boards, CCL (Copper Clad Laminates) is produced by impregnating glass fiber cloth with epoxy resin, and then processing it to form an adhesive film A with a certain thickness to serve as insulation and support between electronic components. Traditionally, Figure 1 As shown, the thickness of adhesive film is mostly measured by manual weighing. After the processing of adhesive film A is completed, operator C uses cutting tool T to cut a specific area and weigh it to deduce the thickness value of adhesive film A. However, in the process of manual weighing, the result of measuring thickness after cutting is easily affected by the cutting tool, cutting angle, cutting proficiency, and even the state of the adhesive film A being broken after cutting. Moreover, when cutting adhesive film A, the CCL preparation machine needs to be offline for operation, and it is impossible to measure the thickness online to correct the relevant parameters of the CCL preparation machine in real time. On the other hand, it is also difficult to obtain relevant information about the uniformity of epoxy resin impregnated in glass fiber cloth by traditional methods. In addition, there is also a method of using laser to measure thickness to solve the above problems, but it is often because the laser spot is too small, and the surface of the adhesive film has different roughness, resulting in ups and downs, so that the laser with a small spot is also prone to measurement errors.

[0004] Therefore, the present invention describes how to effectively improve the traditional shortcomings of thickness measurement results caused by manual weighing and the inability to measure thickness in real time through innovative hardware design. This is still a problem that developers and researchers in related industries need to continue to work hard to overcome and solve. Summary of the invention

[0060] See also Figure 2 A resin content detection device 100 includes: at least one capacitive sensing device 10, including a sensing probe 11, the sensing probe 11 generates or receives a current, the sensing probe 11 does not contact a surface of a non-metallic object M containing resin, and the non-metallic object M containing resin further includes a fiber cloth N, the fiber cloth N can be, for example but not limited to, glass fiber; at least one capacitive corresponding sensing device 20, receives or generates the current, and according to actual needs, the capacitive sensing device 10 and the capacitive corresponding sensing device 20 can be fixed or movable.

[0061] A signal control processing module (not shown) is electrically connected to the capacitive sensing device 10 and the capacitive corresponding sensing device 20, wherein the signal control processing module senses a first capacitance value formed between the capacitive sensing device 10, the fiber cloth N and the capacitive corresponding sensing device 20 and calculates a first voltage, the signal control processing module senses a second capacitance value formed between the capacitive sensing device 10, the non-metallic object M containing resin and the capacitive corresponding sensing device 20 and calculates a second voltage, and the signal control processing module calculates a voltage difference between the second voltage and the first voltage, and obtains a glue content value in a first nonlinear detection curve corresponding to the voltage difference.

[0062] like Figure 2 As shown, the non-metallic object M containing resin is arranged between the capacitive sensing device 10 and the capacitive corresponding sensing device 20. When the capacitive sensing device 10 generates a current, the current passes through the non-metallic object M containing resin and is received by the capacitive corresponding sensing device 20, and the signal control processing module can sense the second capacitance value and calculate the second voltage.

The signal control processing module senses the second capacitance value of the non-metallic test object M containing resin and calculates the second voltage, while the signal control processing module senses the first capacitance value of only the fiber cloth N and calculates the first voltage. The second voltage is higher than the first voltage. When the second voltage is subtracted from the first voltage, a voltage difference is obtained. The voltage difference represents the state of the non-metallic test object M containing resin after deducting the fiber cloth N. Furthermore, as Figure 3 As shown, one side of the non-metallic object M containing resin is the first position, and the other side is the second position. The distance between the first position and the second position is the measurement width W. The measurement width W is the range of capacitance values ​​of the non-metallic object M containing resin that can be sensed by the sensing probe 11. The direction of movement of the sensing probe 11 can be one-dimensional movement, two-dimensional movement, or three-dimensional movement.

[0064] Please also read Figure 4 As shown, the sensing probe 11 moves and senses between a first position and a second position in the non-metallic test object M containing resin. When the moving direction of the sensing probe 11 is not parallel to the moving direction D of the non-metallic test object M containing resin, a measuring path P sensed by the sensing probe 11 is as follows: Figure 5A On the other hand, when the non-metallic object M containing resin is not moving, the sensing probe 11 moves and senses the measuring path P as shown. Figure 5B Or, when the non-metallic object M containing resin is moving, one or more sensing probes 11 are fixedly arranged at the same detection position, and a measurement path P sensed by the sensing probe 11 is as shown. Figure 5C As shown, in actual implementation, the sensing probe 11 can be moved alone or the non-metallic object M containing resin can be moved alone according to actual needs, or the sensing probe 11 can be moved and the non-metallic object M containing resin can be moved at the same time.

[0065] like Figure 7As shown, the X axis is the glue content (RC%), and the Y axis is the voltage difference (V). The first nonlinear detection curve is composed of the relationship between a plurality of voltage differences and their corresponding glue content values. The voltage difference corresponding to each position is Figure 7 The corresponding rubber content (RC%) can be found in the first nonlinear detection curve shown.

The calculation formula of the glue content value is: RC%=(AW-BW) / AW, where RC% (Resin Content (%)) is the glue content value, AW is the weight of the non-metallic test object M containing resin, and BW is the weight of the fiber cloth N. (temporary)

[0068] In one embodiment of the present invention, the resin content detection device 100 further includes a glue content monitoring module (not shown in the figure). The glue content monitoring module pre-stores a glue content threshold. When the glue content value is lower than or higher than the glue content threshold, a warning signal is displayed. In actual implementation, the warning signal can display different light colors or different light flashing frequencies, or emit different warning sounds, etc., to remind the operator to take subsequent measures. The number of times the warning signal is issued each time can also be used as a basis for the operator to perform subsequent quality management to check the quality yield of each batch of non-metallic test objects M containing resin. For example: when the glue content value is higher than the glue content threshold, the light color is red; when the glue content value is within the normal glue content threshold range, the light color is green; when the glue content value is lower than the glue content threshold, the light color is yellow.

[0069] Please also read Figure 8 and Fig. 9 The non-metallic test object M containing resin includes a resin R and the fiber cloth N. The non-metallic test object M containing resin can be made by impregnating the fiber cloth N with a resin R. The resin can be, for example but not limited to, epoxy resin or organic compounds.

[0070] In one embodiment of the present invention, the signal control processing module further includes a communication module (not shown), which is electrically connected to the signal control processing module. The signal control processing module can generate a notification signal through a communication module when the relevant numerical value generated by the resin content detection equipment 100 or when the warning signal occurs or the process of the process equipment is corrected, and transmit it to an electronic device, so that the operator can understand the operating status of the resin content detection equipment 100 at any time. The electronic device can be an electronic device with wireless communication such as a smart phone, a smart watch or a tablet. Furthermore, the signal control processing module can also include a programmable controller, so that the operator can also remotely set and operate the resin content detection equipment 100 through the electronic device and the communication module.

[0071] Please also read Fig.10 , Fig.11 and Fig.13 The resin content detection device 100 further includes a conveying member 40, the conveying member 40 includes a roller 41 and two pivots 42, the two sides of the roller 41 are pivoted on the pivots 42, and the roller 41 is used to carry the non-metallic test object M containing resin. The non-metallic test object M containing resin can be moved by the rotation of the roller 41. Fig.11 As shown, the roller 41 is disposed below the sensing probe 11, or as Fig.13 As shown, the roller 41 can also be disposed on both sides of the sensing probe 11 , and the non-metallic objects M containing resin can be sensed by the sensing probe 11 in sequence by the rotation of the roller 41 .

[0072] The resin content detection device 100 further includes a moving platform 30, the moving platform 30 has a sliding seat 31 and a slide rail module 32, the sliding seat 31 is movably arranged on the slide rail module 32, the slide rail module 32 may have at least one track, the sliding seat 31 can slide on the track, the sliding seat 31 can be used to set the capacitive sensing device 10 or the capacitive corresponding sensing device 20, the sliding seat 31 can slide freely between the slide rail modules 32 according to the configuration of the slide rail module 32, and the sliding seat 31 itself can have a lifting module, the lifting module is used to lift the capacitive sensing device 10 or the capacitive corresponding sensing device 20, such as Fig.10 As shown, the slide rail module 32 is arranged above the conveying member 40, and the sensing probe 11 is installed on the sliding seat 31. When the resin content detection equipment 100 is in operation, the sliding seat 31 can drive the sensing probe 11 to rise and fall or move left and right to sense the non-metallic object M containing resin at different positions.

[0073] The resin content detection device 100 further includes a correction adjustment module (not shown), which pre-stores a correction glue content threshold value. When the glue content value is lower or higher than the correction glue content threshold value, the process of a process device is corrected. The process device can be the resin content detection device 100 of the present invention or other devices under the same process. The process can be a process parameter or a process condition. By correcting the process of a process device, the resin content detection device 100 can be optimized to operate. For example, taking the process parameters of the resin content detection device 100 as an example, By adjusting the parameters such as the moving speed, moving direction or moving mode of the sliding seat 31 of the moving platform 30, the speed of the roller rotation of the conveying member 40, or the current generated by the capacitive sensing device 10 or the capacitive corresponding sensing device 20, the frequency or range of sensing the non-metallic test object M containing resin can be increased to assist operators in discovering errors. By reducing the time after the resin content detection device 100 senses an abnormal value of the glue content, the resin content detection device 100 can quickly perform troubleshooting and resume normal operation. Alternatively, by adjusting the above parameters, the frequency or range of sensing the non-metallic test object M containing resin can be reduced, or even the operation can be suspended or stopped, so that the operator can conveniently repair the resin content detection equipment 100, and the process conditions can be the ambient temperature conditions or humidity conditions during the sensing operation. When the ambient temperature conditions or humidity conditions during the operation affect the sensing accuracy of the resin content detection equipment 100, resulting in the sensed glue content value being lower or higher than the corrected glue content threshold, other equipment under the same process can be adjusted through the correction adjustment module to restore the ambient temperature or humidity during the operation to normal. In actual implementation, the process conditions are adjusted through the correction adjustment module so that the resin content detection equipment 100 can automatically troubleshoot and resume normal operation, thereby reducing the risk of human operating errors and reducing labor costs.
