Description

Technical Field

[0001] This invention relates to the field of electronic manufacturing technology, and in particular to a three-axis micro-milling device for microchannel molding. Background Technology

[0002] With the rapid development of electronic technology, circuit boards are being used more and more widely in various electronic devices, and the performance requirements for circuit boards are also increasing. As an important structure on circuit boards, the molding quality of microchannels directly affects the performance and reliability of the circuit board.

[0003] Currently, in the microfluidic forming process of circuit boards, three-axis micromilling technology is widely used due to its maturity and precision, which meet the requirements of microfluidic forming. Therefore, three-axis micromilling devices are commonly used for microfluidic forming. However, there are significant shortcomings in the supervision of personnel operation during this process. The operator's behavior is crucial to processing quality and equipment safety. However, there is a lack of effective automatic monitoring methods in the current microfluidic forming process. It is impossible to accurately determine in real time whether operators are checking the equipment as required to inspect for tool wear, loose workpiece clamping, or abnormal processing parameters—issues that may affect processing quality. Since microfluidic forming is costly, failure to address these issues promptly can lead to scrapping and economic losses. Furthermore, it is difficult to effectively monitor whether operators are away from their posts. If operators are absent for extended periods, and malfunctions or abnormalities occur during equipment operation, they cannot be addressed in time, potentially leading to equipment damage or even safety accidents and further economic losses. Furthermore, even after a staff member's violation is detected and an alert is activated, there is a lack of a reasonable management mechanism for turning off the alert. Staff members may turn off the alert at will, which greatly reduces the binding effect of the alert and fails to truly motivate staff members to comply with the regulations, making it difficult to guarantee the standardization and effectiveness of management. Summary of the Invention

[0004] This invention relates to a three-axis micro-milling device for microchannel forming, which solves the problem that although the three-axis micro-milling device is commonly used for microchannel forming of circuit boards, it lacks effective automatic monitoring methods and cannot accurately determine whether personnel have checked according to regulations or left their posts.

[0005] This invention provides a three-axis micro-milling device for microchannel molding, specifically comprising: a worktable, a base support, and an operation panel for command input fixedly mounted on one side of the worktable; a three-axis motion mechanism capable of three-way linear motion mounted above the worktable; a spindle mechanism mounted on the Z-axis motion component of the three-axis motion mechanism, with a micro-milling cutter mounted on the output end of the spindle mechanism; a support platform mounted below the worktable, with a set of pyroelectric infrared sensors fixedly mounted on each of the four side faces of the support platform; a microcontroller, a signal acquisition module, and a surrounding observation and timing module are housed inside the support platform; and four sets of pyroelectric infrared sensors are also included. All are electrically connected to the microcontroller; the signal acquisition module is electrically connected to the microcontroller and is used to acquire the electrical signals output by the four sets of pyroelectric infrared sensors, convert them into digital signals and transmit them to the microcontroller so that the microcontroller can process and analyze the signals; the observation and judgment timing module is electrically connected to the microcontroller and its timing value is set to five minutes; when the microcontroller receives the trigger signal from the four sets of pyroelectric infrared sensors through the signal acquisition module, and after processing and judging it, determines that the four sets of pyroelectric infrared sensors are all in the triggered state, the microcontroller controls the observation and judgment timing module to perform a reset operation.

[0006] Furthermore, the support platform is also equipped with a displacement determination timing module a and a displacement determination timing module b, which are electrically connected to the microcontroller. The displacement determination timing module a is set to a timing value of three minutes, and the displacement determination timing module b is set to a timing value of five seconds.

[0007] Furthermore, a set of departure detection flashing lights is fixedly installed on each of the four side end faces of the support platform, and all four sets of departure detection flashing lights are electrically connected to the microcontroller; when the timing value of departure detection timing module a is reached, departure detection timing module a feeds back a signal to the microcontroller, and the microcontroller controls departure detection timing module b and departure detection flashing lights to start.

[0008] Furthermore, a set of buzzer-like alarms is fixedly installed on the left end face of the support platform. The alarms are electrically connected to the microcontroller. When the timing value of the departure determination timing module b is reached, the departure determination timing module b sends a feedback signal to the microcontroller, and the microcontroller controls the alarm to start. Similarly, when the timing value of the observation determination timing module is reached, the observation determination timing module sends a feedback signal to the microcontroller, and the microcontroller controls the alarm to start.

[0009] Furthermore, a set of displacement determination reset switches, which are tactile switches, are fixedly installed on the left end face of the support platform. The displacement determination reset switches are electrically connected to the microcontroller. When the displacement determination reset switches are in the pressed start state, the displacement determination reset switches provide feedback signals to the microcontroller, which controls the displacement determination timing module b to turn off and controls the displacement determination timing module a to restart the timing.

[0010] Furthermore, a threaded groove is provided on the left end face of the support platform, and a set of off-position warning shut-off switches, which are tactile switches, are fixedly installed at the center of the right side of the inner end of the threaded groove. The off-position warning shut-off switches are electrically connected to the microcontroller. When the off-position warning shut-off switches are in the pressed-on state, the off-position warning shut-off switches provide feedback signals to the microcontroller, and the microcontroller controls the alarm in the activated state to turn off.

[0011] Furthermore, a pressing stud is installed in the threaded groove. When a force is applied to the pressing stud, causing it to rotate inward along the thread direction of the threaded groove and reach a tightened state, the end of the pressing stud facing the off-position warning switch will press against the button end of the off-position warning switch. At this time, the button end of the off-position warning switch is subjected to the pressure applied by the pressing stud, and the off-position warning switch is in the pressed-on state.

[0012] Furthermore, the left end face of the pressing stud has an elliptical groove at its axial center, and a torsion fitting block that matches its structural dimensions is detachably inserted into the torsion fitting groove. The axial center of the torsion fitting block has a hexagonal opening for torsion fitting.

[0013] This invention provides a three-axis micro-milling device for microchannel forming, which has the following beneficial effects: This invention precisely controls a three-axis micro-milling device via an operation panel, strictly setting processing parameters to achieve high-precision machining and forming of circuit board microchannels. To ensure processing quality, during the circuit board microchannel machining process, this invention utilizes a synchronous operation of a perimeter observation and departure timing module to automatically monitor and judge the operator's actions. Firstly, in conjunction with the sensing trigger of pyroelectric infrared sensors arranged around the support platform, it automatically monitors whether the operator has circled the platform as required. If it determines that the operation has not been performed according to regulations, based on feedback from the perimeter observation and departure timing module, it activates a control alarm, thereby providing a warning reminder to the operator for the non-compliance. Second, in conjunction with the timing feedback from the departure judgment timing module a and departure judgment timing module b, the system automatically monitors whether staff members have violated regulations by leaving their posts. If a violation is detected, the system also activates an alarm to warn and urge staff members to comply with the rules. The alarm can be turned off by using a twisting block carried by the management personnel. This mandatory intervention by the management personnel ensures that violations are recorded. This mandatory intervention will maximize the incentive for staff to strictly abide by the regulations, avoid violations, greatly improve management standardization and effectiveness, ensure processing quality and equipment operation safety, and reduce processing errors, scrap, and equipment malfunctions.

The signal acquisition module 2011 is electrically connected to the microcontroller 2015 and is used to acquire the electrical signals output by the four sets of pyroelectric infrared sensors 202, convert them into digital signals and transmit them to the microcontroller 2015 so that the microcontroller 2015 can process and analyze the signals; the observation and judgment timing module 2012 is electrically connected to the microcontroller 2015 and its timing value is set to five minutes; when the microcontroller 2015 receives the trigger signal from the four sets of pyroelectric infrared sensors 202 through the signal acquisition module 2011, and after processing and judging it, determines that all four sets of pyroelectric infrared sensors 202 are in the trigger state, the microcontroller 2015 controls the observation and judgment timing module 2012 to perform a reset operation.

[0019] In this embodiment of the invention, the support platform 2 is further equipped with a displacement determination timing module a2013 and a displacement determination timing module b2014 electrically connected to the microcontroller 2015. The timing value of the displacement determination timing module a2013 is set to three minutes; the timing value of the displacement determination timing module b2014 is set to five seconds. A set of displacement determination flashing lights 201 are also fixedly installed on each of the four side end faces of the support platform 2, and all four sets of displacement determination flashing lights 201 are electrically connected to the microcontroller 2015. When the timing value of the displacement determination timing module a2013 is reached, the displacement determination timing module a2013 sends a feedback signal to the microcontroller 2015, and the microcontroller 2015 controls the displacement determination timing module b2014 and the displacement determination flashing lights 201 to start.

[0020] In this embodiment of the invention, a threaded groove 208 is provided on the left end face of the support platform 2. A set of off-position warning and shut-off switches 209, which are tactile switches, are fixedly installed at the center of the right side of the inner end of the threaded groove 208.

A pressing stud 205 is installed in the threaded groove 208. When a force is applied to the pressing stud 205, it is pushed inward along the thread direction of the threaded groove 208. When rotated and tightened, the end of the pressing stud 205 facing the off-position warning switch 209 will press against the button end of the off-position warning switch 209. At this time, the button end of the off-position warning switch 209 is subjected to pressure applied by the pressing stud 205, and the off-position warning switch 209 is in the pressed-on state. A torsion fitting groove 2010 with an elliptical groove structure is provided at the axial part of the left end face of the pressing stud 205. A torsion fitting block 206 with matching structural dimensions is detachably inserted into the torsion fitting groove 2010. A torsion fitting opening 207 with a hexagonal opening structure is provided at the axial part of the torsion fitting block 206.

[0021] The working principle of this embodiment: First, the circuit board is accurately fixed on the fixture of the support platform 2 to ensure that it is stable and does not shake. Then, the corresponding instructions are input through the operation panel 101 to perform the initialization operation of the three-axis micro milling device. This process includes setting various key processing parameters, such as accurately setting the milling speed, feed rate and cutting depth. After initialization, the three-axis motion mechanism 102 responds to the commands input by the operation panel 101 and performs precise linear motion in the X, Y, and Z directions, moving strictly according to the preset path. The spindle mechanism 103 is mounted on the Z-axis motion component of the three-axis motion mechanism 102 and can drive the micro-milling cutter 104 to rotate at high speed. The high-speed rotating micro-milling cutter 104 mills the microchannels of the circuit board on the support platform 2. During the milling process, the cutter contacts the surface of the circuit board and gradually removes the material. With the orderly movement of the three-axis motion mechanism 102, the shape of the microchannels gradually takes shape until the microchannels on the circuit board completely meet the design requirements, completing the forming process of the microchannels of the circuit board. During the microchannel fabrication of the circuit board, the observation and judgment timing module 2012 and the displacement judgment timing module a2013 are started synchronously. To ensure processing quality, according to regulations, during the microchannel processing of circuit boards, staff need to walk around the micromilling device to check for issues that may affect processing quality, such as tool wear, loose workpiece clamping, and abnormal processing parameters. This allows for timely adjustments and handling to avoid processing errors or scrap due to negligence, thereby ensuring the forming quality of the circuit board microchannels. When staff perform the surrounding inspection operation as required, the pyroelectric infrared sensors 202 arranged around the support platform 2 will sequentially sense the infrared signals of the staff's human body. At the same time, the signal acquisition module 2011 collects the electrical signals output by the four sets of pyroelectric infrared sensors 202, converts them into digital signals, and transmits them to the microcontroller 2015 so that the microcontroller 2015 can process and analyze the signals. When the microcontroller 2015 receives the trigger signals from the four sets of pyroelectric infrared sensors 202 through the signal acquisition module 2011, and after processing and judging, determines that all four sets of pyroelectric infrared sensors 202 are in the triggered state, the microcontroller 2015 controls the surrounding observation judgment timing module 2012 to perform a reset operation. If the staff fails to perform the surrounding inspection operation as required, all four sets of pyroelectric infrared sensors 202 will not be triggered before the timing value (five minutes) of the surrounding observation and judgment timing module 2012 is reached. When the timing value (five minutes) of the surrounding observation and judgment timing module 2012 is reached, the surrounding observation and judgment timing module 2012 will send a feedback signal to the microcontroller 2015. The microcontroller 2015 will control the alarm 203 to start, and the alarm 203 will warn the current staff that they have not performed the operation as required, reminding them to check whether the tool is worn, whether the workpiece is clamped loosely, whether the processing parameters are abnormal, and other issues that may affect the processing quality. As mentioned above, in order to ensure processing quality, according to regulations, during the microchannel processing of circuit boards, the staff must not leave the micromilling device. This is to avoid the inability to deal with malfunctions or abnormalities that occur during the operation of the device due to the staff's long-term absence, which could lead to damage to the device or even safety accidents. If the staff member does not leave their post during the microfluidic processing of the circuit board as required, when the timer value (three minutes) of the departure judgment timing module a2013 is reached, the departure judgment timing module a2013 sends a feedback signal to the microcontroller 2015. The microcontroller 2015 controls the departure judgment flashing light 201 and the departure judgment timing module b2014 to start. Since the departure judgment flashing lights 201 are arranged around the support platform 2, the sudden flashing of the departure judgment flashing light 201 will remind the current staff member. At this time, the staff member can press the departure judgment reset switch 204, and the departure judgment reset switch 204 sends a feedback signal to the microcontroller 2015. The microcontroller 2015 controls the departure judgment timing module b2014 to turn off and controls the departure judgment timing module a2013 to start timing again. If a worker leaves their post during the microfluidic processing of the circuit board, they will not be able to press the departure reset switch 204 before the departure determination timing module b2014 reaches its timing value (five seconds). When the departure determination timing module b2014 reaches its timing value, it will send a feedback signal to the microcontroller 2015. The microcontroller 2015 will then activate the alarm 203 to warn and remind the worker of their departure, thereby attracting the attention of relevant personnel on site and urging them to return to their posts as soon as possible. This will ensure the smooth progress of the microfluidic processing of the circuit board and avoid adverse consequences such as processing quality problems and equipment malfunctions that may result from personnel leaving their posts. After the aforementioned alarm 203 is activated, when it needs to be turned off, the off-position alarm off switch 209 must be pressed to turn off the alarm 203. However, the off-position alarm off switch 209 is located inside the threaded groove 208 and is blocked by the pressing stud 205. The alarm 203 can only be turned off by rotating the pressing stud 205 inward along the thread direction of the threaded groove 208 to press the off-position alarm off switch 209. However, the torsion block 206, which matches the structural dimensions of the torsion groove 2010, is carried by the management personnel, making it impossible for the current staff to use common tools, such as screwdrivers, to insert into the elliptical groove structure of the torsion groove 2010. Therefore, it is impossible to rotate the pressing stud 205 inward along the thread direction of the threaded groove 208. Thus, when the alarm 203 is activated, if the staff wants to turn it off, they must contact the management personnel in time. When the management personnel arrive at the site, they insert the torsion block 206 into the torsion groove 2010 and rotate the torsion block 206 using an Allen wrench that engages with the torsion opening 207. This simultaneously drives the pressing stud 205 to rotate inward along the thread direction of the threaded groove 208 until the end of the pressing stud 205 facing the off-position warning switch 209 presses against the button end of the off-position warning switch 209. Then, the off-position warning switch 209 sends a feedback signal to the microcontroller 2015, which controls the alarm 203 in the activated state to turn off. Through this mandatory operation procedure design, if a staff member violates the regulations and causes the alarm 203 to be activated, it will be necessary to contact the management personnel to turn off the alarm 203. This process can be accurately recorded by the system. From a management perspective, this design can encourage staff to strictly abide by the regulations because they clearly know that violations will be recorded. Therefore, this design can minimize staff violations, effectively improve the standardization and effectiveness of management, and ensure the normal operation of the workflow and the safe use of the equipment.
