Description

Technical Field

[0001] The invention belongs to the technical field of laser thickness measuring equipment, and in particular relates to continuous laser thickness measuring equipment for coating wet films and dry films. Background Art

[0002] In modern industry, thin film processing technology plays a key role in electronics, optics, semiconductors and other fields. In the field of thin film processing, dry film and wet film are two common coating technologies, each with unique characteristics and advantages.

[0003] Dry film is a semi-hardened film that requires heating and softening during processing to improve adhesion. While relatively simple and convenient to apply and easy to maintain cleanliness, dry film offers poor coverage of surface defects such as pits and protrusions. Wet film exhibits excellent flowability, effectively filling surface pits and protrusions, thereby improving coverage. Its thin film thickness also means it excels in image resolution, making it particularly suitable for applications requiring high precision.

[0004] Both dry and wet films on circuit boards can provide good protection for the circuit boards and simplify the process. However, due to the large number of dry and wet film locations on the circuit boards, continuous thickness measurement takes a long time. Therefore, there are high requirements for the temperature and humidity of the measurement environment. For example, a high humidity environment can easily cause the circuit boards to absorb moisture, affecting the dielectric properties and increasing the risk of interlayer separation or delamination. Excessively high temperatures may cause aging or performance degradation of the circuit board substrate. At the same time, when the circuit board is covered with air impurity particles, it will also affect the accuracy of the thickness measurement. Summary of the Invention

[0020] (1) A pressing and cleaning mechanism and a ventilation shielding mechanism are provided. When the first cylinder drives the slider to move downward, the pressing roller can press the circuit board on the carrier, thereby ensuring the flatness of the dry and wet films on the circuit board and preventing wrinkles, which is beneficial to improving the accuracy of the thickness measurement data.

Under the action of the gear meshing transmission, it can drive the rotation of the first rotating tooth and transmit the force to the second gear plates at both ends. During the movement, the second gear plate can drive the shielding plate to move synchronously, thereby opening the ventilation hole.

In conjunction with the storage port at the bottom of the box body, it can form a relatively sealed environment with the carrier platform, thereby ensuring a dust-proof effect for thickness measurement for a long time. After the second motor is started, it can drive the second blade on the second movable shaft to rotate and dissipate heat through the transmission effect of the conveyor belt, and can discharge the heat inside the box body in time to prevent the temperature inside the box body from being too high, thereby forming an environment with a relatively constant temperature. In addition, the second motor can drive the laser thickness gauge on the steering rod to rotate. Thickness measurement data at multiple positions can be obtained by rotating the thickness measurement method. In addition, when the output shaft of the second motor drives the cam to rotate, in conjunction with the second spring and the third spring on the resistance block, the rotational motion of the cam can be converted into the linear motion of the push plate and the resistance block. In addition, the meshing transmission effect of the third gear plate and the second rotating tooth on the resistance block can allow the swing brush to perform a reciprocating rotation motion at a certain angle. During the rotation of the swing brush, it can not only play a corresponding heat dissipation effect, but also generate downward wind force and can also play a role in removing particulate impurities on the circuit board. The design is reasonable, the measurement environment is stable, the integrated performance is strong, and the linkage effect is good.

[0022] (3) Set up a conveyor line, which can not only carry and transport circuit boards, but also facilitate reaching the corresponding position points for corresponding cleaning and pressing work, as well as the stable implementation of thickness measurement work, ensuring the stability of data detection and facilitating personnel to carry out subsequent collection and processing.

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Manual Figure 1 and attached Figure 2 As shown, the continuous laser thickness measurement equipment for coating wet film and dry film includes: a conveyor line 1, which is installed on a frame and extends along a preset direction to carry and transport a carrying platform 2;

[0035] The pressing and cleaning mechanism 3 includes fixed blocks 4 placed on both sides of the top of the frame, a slide groove is provided on the fixed block 4 and a slider 5 is movably connected, the top of the slider 5 is connected to a piston rod installed at the bottom of the first cylinder 6, and the bottom of the slider 5 is connected to the strip plate 8 through a first spring 7, the strip plate 8 and the fixed block 4 are integrally formed, and a pressure roller 9 is movably connected between the sliders 5; wherein, a first motor 10 is installed at the center of the outer wall of the strip plate 8 through a first support plate, and the output shaft of the first motor 10 and the rotating wheels 11 at both ends are connected by a first conveyor belt 12 for transmission, one end of the rotating wheel 11 passes through the strip plate 8 and extends to the ventilation hole 13 inside the strip plate 8, the outer wall of the rotating wheel 11 is connected to a first blade 14 adapted thereto, and the rotating wheel 11 is connected to a bracket 15 distributed in an annular manner at the ventilation hole 13 through a bearing.

[0036] Specifically, the pressing and cleaning mechanism 3 is essentially to clean the surface of the circuit board by blowing air when adjusting the flatness of the dry and wet films on the circuit board, thereby ensuring the cleanliness of the circuit board. Moreover, the bearing connected to the bracket 15 at the ventilation hole 13 can not only support and connect the rotating wheel 11, but also increase the corresponding activity space for the movement of the rotating wheel 11, thereby ensuring the free movement of the rotating wheel 11.

[0037] The wrap angles between the first conveyor belt 12 and the output shaft of the first motor 10 and the rotating wheel 11 are designed to be greater than 120 degrees. This can reduce the possibility of slipping. Slipping is caused by overload or insufficient friction, which will seriously affect the efficiency of the transmission. The contact area between the first conveyor belt 12 and the transmission wheel is increased, thereby ensuring the stability of the transmission by increasing the friction.

[0038] When the slider 5 moves on the vertical slide groove, it can not only guide the movement of the slider to prevent deviation during the movement of the slider 5, but also cooperate with the first spring 7 to provide a better buffering and adjustment effect for the slider 5 when it collides with the top of the strip plate 8, thereby effectively increasing the safety of the device.

[0039] refer to Figure 2 、 Figure 4 、 Figure 5 and Figure 6 , the ventilation shielding mechanism 16, the ventilation shielding mechanism 16 includes a synchronization rod 17 mounted on the slider 5, the bottom of the synchronization rod 17 passes through the cover 18 and extends to the first gear plate 19, the outer wall of the first gear plate 19 is engaged with a first rotating tooth 20, and the upper and lower ends of the first rotating tooth 20 are engaged with a second gear plate 21 that moves in the opposite direction, and the extending end of the second gear plate 21 is connected to a shielding plate 22 placed at the ventilation hole 13.

[0040] A strip groove connected to the extended end of the second gear plate 21 is provided in the length direction of the strip plate 8. A plug-in portion is installed on the top of the shielding plate 22 and is connected to the extended end of the second gear plate 21 by plugging and fixing. The first gear plate 19 and the second gear plate 21 are kept vertically staggered.

[0041] A pressing and cleaning mechanism 3 and a ventilation and shielding mechanism 16 are provided. When the first cylinder 6 drives the slider 5 to move downward, the pressing roller 9 can press the circuit board on the carrier 2, thereby ensuring the flatness of the dry and wet films on the circuit board and preventing wrinkles, which is beneficial to the accuracy of the thickness measurement data. In addition, when the slider 5 moves downward, it can drive the first gear plate 19 to move downward. Under the action of the gear meshing transmission, it can drive the rotation of the first rotating tooth 20 and transmit the force to the second gear plates 21 at both ends. The second gear plates 21 are in the process of moving. , it can drive the baffle plate 22 to move synchronously, thereby opening the ventilation hole 13, and cooperate with the first motor 10. Under the transmission action of the conveyor belt, it can drive the rotating wheels 11 at both ends to move, so that the first blade 14 can play the role of blowing and cleaning, preventing particulate impurities from falling onto the circuit board, further improving the accuracy of the thickness measurement data. At the same time, when the first cylinder 6 drives the piston rod to move upward, it can drive the baffle plate 22 to close the ventilation hole 13, preventing dust from falling inside the strip plate 8 when not in use, thereby ensuring the cleanliness of the device.

[0042] The cover body 18 is arranged in a cross shape, and the bottom of the cover body 18 is fixed to the frame through a panel. The synchronization rod 17 is provided with a guide hole placed on the top of the cover body 18. A pressing cavity is formed between the pressure roller 9 and the supporting platform 2. Both ends of the outer wall of the slider 5 are connected with protrusions, and the protrusions are connected with embedded openings along the height direction of the side wall of the slide groove.

[0043] Specifically, the embedded opening on the slide groove has a corresponding guiding effect on the movement of the slider 5, and the guide hole on the cover body 18 provides a free movement space for the up and down movement of the synchronization rod 17. The vertical staggered arrangement of the first gear plate 19 and the second gear plate 21 can avoid interference between the transmission parts during the movement, ensuring that the transmission parts can move freely and normally. At the same time, the cross-shaped cover body 18 can provide corresponding supporting movement space for both the first gear plate 19 and the second gear plate 21, and can also ensure the free movement of the extended end of the second gear plate 21.

[0044] refer to Figure 7 and Figure 8The continuous laser thickness measuring equipment for coating wet and dry films also includes a temperature-regulating and thickness-measuring mechanism 23. The temperature-regulating and thickness-measuring mechanism 23 includes a U-shaped frame 24 fixed on the frame. Second cylinders 25 are connected to both sides of the top of the U-shaped frame 24. The piston rod at the bottom of the second cylinder 25 passes through the U-shaped frame 24 and extends into the box body 26. A receiving port is provided at the bottom of the box body 26, and a second motor 27 is installed at the center of the top of the box body 26. The output shaft of the second motor 27 extends to a cam 28 and a steering rod 29 in sequence. A laser thickness gauge 30 is detachably installed at the bottom of the steering rod 29.

[0045] Both ends of the outer wall of the cam 28 are in contact with and fit on the push plate 31. The push plate 31 and the resistance block 32 are connected by a second spring 33. One end of the resistance block 32 is connected to the inner wall of the box body 26 by a third spring 34, and a third gear plate 35 is integrally installed on the bottom of the resistance block 32. The bottom of the third gear plate 35 is transmission-engaged with a second rotating tooth 37 fixed on the first movable shaft 36. Both ends of the first movable shaft 36 are provided with rolling grooves placed on the edge of the inner wall of the box body 26, and an oscillating brush 38 adapted to it is installed on the outer wall of the first movable shaft 36.

[0046] Specifically, the oscillating brush 38 is arranged vertically to the resistance block 32, and an opening is connected to the top of the oscillating brush 38 near the second rotating tooth 37. An active cavity is formed inside the box body 26 between the cam 28 and the push plate 31. After the second motor 27 is started, it can drive the cam 28 to rotate. Cooperating with the resistance block 32 on the third spring 34, during the contact and bonding process with the push plate 31, the rotational motion of the cam 28 can be converted into a linear motion of the resistance block 32, and under the action of the gear meshing transmission, the oscillating brush 38 on the first movable shaft 36 can be driven to rotate back and forth at a certain angle. During the movement, the oscillating brush 38 can not only remove foreign particles on the circuit board to the outside through the action of the swinging wind force, but also perform secondary cleaning of the foreign particles on the circuit board during the bonding cleaning process, thereby further ensuring the cleanliness of the circuit board surface.

[0047] By extension, the laser thickness gauge 30 uses the reflection of laser light to measure the thickness of an object. Simply put, the laser thickness gauge emits a laser beam that hits the object, then receives the reflected light signal and measures the changes in the position of the light spot during this process to calculate the thickness of the object.

[0048] A temperature regulating and thickness measuring mechanism 23 is provided. After the second cylinder 25 is started, it can drive the box body 26 to move up and down. In conjunction with the receiving port at the bottom of the box body 26, it can form a relatively sealed environment with the carrier platform 2, thereby ensuring a dust-proof effect that can measure the thickness for a long time. After the second motor 27 is started, it can drive the second blade 41 on the second movable shaft 40 to rotate and dissipate heat through the transmission effect of the conveyor belt, so that the heat inside the box body 26 can be discharged in time to prevent the temperature inside the box body 26 from being too high, thereby forming an environment with a relatively constant temperature. In addition, the second motor 27 can drive the laser thickness gauge 30 on the steering rod 29 to rotate, and the thickness measurement can be performed by rotating. Thickness measurement data at multiple positions can be obtained. In addition, when the output shaft of the second motor 27 drives the cam 28 to rotate, the second spring 33 and the third spring 34 on the resistance block 32 can convert the rotational motion of the cam 28 into a linear motion of the push plate 31 and the resistance block 32. Moreover, the meshing transmission effect of the third gear plate 35 and the second rotating tooth 37 on the resistance block 32 allows the oscillating brush 38 to perform a reciprocating rotation motion at a certain angle. During the rotation of the oscillating brush 38, it can not only achieve a corresponding heat dissipation effect, but also generate downward wind force and can also clear particulate impurities on the circuit board. The design is reasonable, the measurement environment is stable, the integrated performance is strong, and the linkage effect is good.

[0049] The upper and lower ends of the outer wall of the output shaft of the second motor 27 are transmission connected to the second movable shaft 40 through the second conveyor belt 39. The second movable shaft 40 is equipped with a second blade 41 placed at the notch of the box body 26, and the bottom of the second movable shaft 40 is equipped with a crossbeam 42 fixed to the side wall of the box body 26 through the second support plate. The top of the second support plate is provided with an annular groove connected to the second movable shaft 40, and the annular groove is symmetrically arranged relative to the center of the box body 26.

[0050] A positioning ring is provided on the edge of the outer wall of the annular groove and is placed on the second support plate. A positioning hole is provided between one end of the crossbeam 42 and the inner wall of the box body 26, and is locked and fixed by a bolt assembly. By extension, a ball connected to the second movable shaft 40 can be added to the bottom of the inner wall of the annular groove. In this way, the rotation of the second movable shaft 40 is achieved by rolling friction, and the transmission by rolling friction can effectively reduce friction, reduce friction damage, and increase the service life of the device. Since the ball assembly is a conventional technical means for those skilled in the art, it is not drawn in the drawings of the specification, but it does not affect the effective implementation of the technical solution of this patent.
