Description

Technical Field

[0001] The invention relates to the technical field of color measurement, in particular to a solder paste printer with a color mark sensor. Background Art

[0002] A solder paste printer, also known as an SMT printer, is an automated device specifically designed to accurately print solder paste on PCBs (printed circuit boards). Solder paste is a viscous metal alloy mixture used to connect electronic components on circuit boards. A solder paste printer is generally composed of mechanisms such as plate loading, solder paste addition, stamping, and circuit board feeding. It is equipped with advanced systems such as a visual system, a scraper system, and a stencil cleaning device. The solder paste is evenly printed on the pads of the circuit board through a scraper. After the solder paste is printed, the trajectory and disconnection of the solder paste line need to be detected. During the detection, color mark sensors are mostly used for detection. In the field of automation, color mark sensors are often used for color detection and positioning. They can accurately identify and track specific color marks or lines. They can detect the color marks of the solder paste lines on the printed circuit board to ensure the quality and accuracy of solder paste printing.

[0003] However, when the existing solder paste printer with a color mark sensor is in use, it is easily affected by external light when using the color mark sensor to detect the solder paste line. At the same time, the circuit board is prone to deviation and shaking, which affects the accuracy of the detection result and further affects the quality of solder paste printing; the lens of the color mark sensor is easily contaminated by impurities such as dust and water stains and is affected by collision, which will also affect its detection accuracy and service life, and also affect the quality of solder paste printing; the color mark sensor is mostly fixed with bolts during installation, which is prone to improper installation, and when used for a long time, it is easy to become loose due to vibration and other reasons, which is not easy to be discovered in time, and it will also affect its detection accuracy and service life, and further affect the quality of solder paste printing.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) This solder paste printer with a color mark sensor is provided with a telescopic mechanism and a moving mechanism. When printing solder paste, the circuit board is conveyed to the bottom of the steel mesh module by the conveying module, and then it is lifted up by the lifting module, and the solder paste is scraped by the scraper module to realize the solder paste printing operation on the circuit board. After printing is completed, the circuit board is lowered by the lifting module and placed on the conveyor belt for conveying. When it is conveyed to the bottom of the moving cover, the conveying is stopped. Then, the first moving plate is driven downward by the lifting module, and the moving cover is driven downward by the telescopic mechanism. When the moving cover abuts against the top of the fixed cover, the circuit board can be covered between the moving cover and the fixed cover. At the same time, the fourth spring is gradually compressed. At this time, the distance between the first moving plate and the moving cover gradually decreases, so that the push plate can be driven downward by the second T-shaped guide rod and the sixth spring. When When the inclined surface abuts against the side wall of the second moving block, the two V-shaped plates can be pushed to move closer to each other through the moving rod, and at the same time, the fifth spring is gradually compressed. When the V-shaped plate abuts against the circuit board, the circuit board can be clamped in the center, and when the first moving plate continues to move downward, the sixth spring can be gradually compressed, which can not only clamp and fix circuit boards of different sizes, but also provide pre-tightening force to achieve a better clamping effect. Then, the lifting module can be opened, and the first moving block can be driven to move through the XY-axis moving module, and the lens and the lifting module can be driven to move, so as to detect the trajectory and disconnection of the solder paste line. During the detection, the circuit board can be covered between the moving cover and the fixed cover to avoid the influence of external light. At the same time, it can be clamped and fixed in the center to avoid its displacement and shaking, thereby ensuring the accuracy of the detection and thus the quality of the solder paste printing.

[0016] (2) This type of solder paste printer with a color mark sensor is provided with a detection mechanism, etc. When the color mark sensor body is installed, the color mark sensor body is fixed to the side wall of the first moving block by multiple bolts. After the fixing is completed, the side wall of the color mark sensor body can be abutted against the end of the push rod, thereby pushing the push rod to move into the first fixed tube and squeezing the hydraulic oil in the hollow cover. At this time, the counterweight plate can be pushed to move upward along the liquid storage tube. When the counterweight plate moves upward, the push rod is driven to slide in the slide groove through the support plate, thereby pushing the pointer to rotate upward along the first rotating shaft, so that the sensing block is away from the proximity switch. At the same time, by observing the scale mark on the arc plate indicated by the pointer, it can be determined whether the color mark sensor body is installed in place. In addition, when the counterweight plate and the hydraulic oil are in contact with each other, the counterweight plate and the hydraulic oil are moved upward. Under the action of , the end of the push rod can always be against the side wall of the color mark sensor body, thereby providing a pre-tightening force, making the color mark sensor body more stable and reliable after installation, ensuring the accuracy of its detection, and when the color mark sensor body becomes loose during use, the counterweight plate and the hydraulic oil can push the push rod to move in the direction away from the first fixed tube. At this time, the counterweight plate will move downward along the liquid storage tube, and at the same time, the support plate will drive the push rod to slide in the slide groove, so that the pointer will rotate downward along the first rotating shaft and drive the sensing block to rotate synchronously. At this time, it can be detected by the proximity switch and an alarm can be sounded by the external alarm to remind the operator to carry out timely maintenance to ensure the accuracy of the color mark sensor body detection and thus ensure the quality of solder paste printing.

[0017] (3) This solder paste printer with a color mark sensor is provided with a cleaning mechanism, etc., and when performing detection, the exhaust fan is started. At this time, the exhaust hood can be used for exhaust operation, and impurities on the surface of the lens and the white light lamp can be absorbed and enter the fixed box through the second fixed pipe. Under the action of the airflow, the rotating plate can be pushed to rotate upward along the second rotating axis and abut against the bottom of the second movable plate, thereby pushing the second movable plate to move upward, and the movable frame can be driven to move upward through the L-shaped plate. At the same time, the first spring is compressed, and the filter screen is exposed at this time. The absorbed impurities are passed through the filter screen. The filtered air enters the blowing hood through the second telescopic tube and the air blowing tube, and is blown onto the surface of the lens and the white light lamp, thereby making the cleaning efficiency of the lens and the white light lamp higher and the effect better, ensuring the accuracy of the detection, and then ensuring the quality of the solder paste printing, and after the detection is completed, the exhaust fan is turned off. At this time, the movable frame can move downward under the action of the first spring, which can not only scrape and clean the surface of the filter to ensure the efficiency and effect of the filtration, but also push the impurities into the collection box and squeeze them to ensure the efficiency and effect of the impurity collection.

[0018] (4) This solder paste printer with a color mark sensor is provided with a rotating mechanism and a second moving component. When the filtered air enters the installation box, it impacts the surface of the blade and can push the rotating rod to rotate. When the rotating rod rotates, it can drive the metal ball to rotate synchronously through the fixed ring. Under the action of centrifugal force, the metal ball moves in a direction away from the rotating rod, and makes the metal ball abut against the bottom of the connecting frame and pushes it to move upward. In addition, the sliding disk is driven to move synchronously through the first set of rods. The third spring is compressed. When the connecting frame moves upward, it can drive the rack to move upward along the guide rod. At the same time, the second spring is compressed and drives the gear rack to move upward. The wheel and the third rotating shaft rotate clockwise, so that the protective cover can be rotated and opened along the third rotating shaft to ensure normal detection of the lens and the white light lamp. After the detection is completed, the exhaust fan is turned off. At this time, the metal ball can be moved and reset in the direction close to the rotating rod under the action of the third spring and disengaged from the connecting frame. At this time, the rack can be moved downward and reset under the action of the second spring, and drive the gear and the third rotating shaft to rotate counterclockwise. At this time, the protective cover can be rotated and closed to protect the lens and the white light lamp from being affected by impurities such as dust and water stains and collisions, thereby ensuring the accuracy of detection and service life, and thus ensuring the quality of solder paste printing.

[0032] Working principle: When in use, when the color mark sensor body 1110 is installed, the color mark sensor body 1110 is fixed to the side wall of the first moving block 1109 by a plurality of bolts 1111. After the fixing is completed, the side wall of the color mark sensor body 1110 can be against the end of the push rod 1303, thereby pushing the push rod 1303 to move into the first fixed tube 1302 and squeezing the hydraulic oil in the hollow cover 1301. At this time, the counterweight plate 1306 can be pushed to move upward along the liquid storage tube 1305.

At the same time, by observing the scale mark 208 on the arc plate 207 indicated by the pointer 205, it can be determined whether the color mark sensor body 1110 is installed in place; When solder paste printing is performed, the circuit board is conveyed to the bottom of the steel mesh module 104 through the conveying module 102, and then it is lifted up by the lifting module 106, and the solder paste is scraped by the scraper module 105 to realize the solder paste printing operation on the circuit board. After printing is completed, the circuit board is lowered by the lifting module 106 and placed on the conveyor belt 107 for transportation. The transportation is stopped when it is transported to the bottom of the movable cover 1106. Then, the first movable plate 1105 is driven downward by the lifting module 1104, and the movable cover 1106 is driven downward by the telescopic mechanism 10.

At the same time, the first movable plate 1105 is driven downward by the lifting module 1104, and the movable cover 1106 is driven downward by the telescopic mechanism 10. When the movable cover 1106 is against the top of the fixed cover 1102, the circuit board can be covered between the movable cover 1106 and the fixed cover 1102. The fourth spring 1003 is gradually compressed. At this time, the distance between the first movable plate 1105 and the movable cover 1106 gradually becomes smaller, so that the push plate 705 can be driven to move downward by the second T-shaped guide rod 704 and the sixth spring 707. When the inclined surface 706 abuts against the side wall of the second movable block 702, the two V-shaped plates 1107 can be pushed to move closer to each other by the movable rod 701.

At the same time, the metal ball 809 can move and reset in the direction close to the rotating rod 803 under the action of the third spring 810 and disengage from the connecting frame 801. At this time, the rack 605 can move and reset downward under the action of the second spring 904, and drive the gear 604 and the third rotating shaft 602 to rotate counterclockwise.
