Description

Technical Field

[0001] This utility model relates to the field of glass processing technology, specifically to an integrated device for printing and drying conductive silver paste on glass. Background Technology

[0002] In the field of glass deep processing, especially in the manufacture of products such as electronic glass, photovoltaic glass, or touch screen glass, it is often necessary to print precise conductive silver paste lines on the surface of glass substrates. The printing quality of these lines directly affects the conductivity, signal transmission stability, and final product yield. These conductive silver paste lines are not simply decorative structures, but rather bear the core functions of the product. In electronic glass, they are the key channels for electrical signal transmission, ensuring data interaction between the chip and the display module; in photovoltaic glass, they are responsible for collecting the electrical energy converted from solar cells and transmitting it to the junction box with low loss; and in touch screen glass, they directly determine the accurate recognition and rapid response of touch commands.

[0003] Traditional glass conductive silver paste processing typically employs a separate printing and drying process. This split production method is prone to problems such as scratches, displacement, or deformation of uncured silver paste lines due to vibration and collisions, affecting product consistency and accuracy. In addition, existing printing mechanisms often use a single motor coupled with a lead screw or cylinder to drive the printing head, which is prone to uneven load due to single-point drive, causing the printing head to jam, fluctuate in speed, or tilt slightly during descent or elevation, making it difficult to meet the requirements for printing accuracy. Furthermore, the height adjustment mechanism of the printing component is often fixed, making it difficult to adapt to the printing needs of glass substrates with different thicknesses. Therefore, those skilled in the art provide an integrated glass conductive silver paste printing and drying device to solve the problems mentioned in the background art. Utility Model Content

[0004] The purpose of this invention is to provide an integrated device for printing and drying conductive silver paste on glass, thereby solving the problems mentioned in the background section of the prior art.

[0005] This utility model provides the following technical solution: an integrated device for printing and drying conductive silver paste on glass, comprising a base column, a conveying mechanism for conveying glass to various processing areas at the upper end of the base column, a printing component for smoothly printing on the glass at one side of the upper end of the conveying mechanism, a fine-tuning lifting mechanism for slightly adjusting the height of the printing component at the center of the upper end of the conveying mechanism, and a drying component for drying the conductive silver paste brushed on the glass at the other side of the upper end of the conveying mechanism.

[0006] As a preferred embodiment of the above technical solution, the printing component includes a numerical marking ruler, which is fixedly connected to the upper end of the conveying component near one side edge. The upper end of the conveying mechanism is symmetrically fixedly connected to fixed bases near both sides edge. Each of the four fixed bases has a sliding column slidably fitted inside. The upper end of the four sliding columns is fixedly connected to a top plate, and the lower center of the top plate is fixedly connected to a slide rail.

[0007] As a preferred embodiment of the above technical solution, a fixing plate is fixedly connected to the side wall of the top plate near the numerical scale, and a pointer is fixedly connected to the side of the fixing plate near the numerical scale.

[0008] As a preferred embodiment of the above technical solution, the lower end of the top plate is symmetrically fixedly connected to two side edges, wherein motors are fixedly connected to the two side walls of the two fixed columns that are far apart from each other, drive wheels are fixedly connected to the output ends of the two motors, transmission belts are meshed with the outer walls of the two drive wheels, and transmission wheels are meshed with the ends of the two transmission belts that are far away from the two drive wheels.

[0009] As a preferred embodiment of the above technical solution, fixed protrusions are symmetrically fixedly connected to the lower outer sides of the two transmission belts, and a printing base is fixedly connected between the two sets of fixed protrusions. A printing head is fixedly connected to the lower center of the printing base, and a sliding sleeve is fixedly connected to the upper center of the printing base.

[0010] As a preferred embodiment of the above technical solution, the fine-tuning lifting mechanism includes a second fixed plate, which is symmetrically fixedly connected to the upper end of the conveying mechanism on both sides. A rotating disk is fixedly connected to one side of one of the second fixed plates. A screw is fixedly connected to the output shaft of the rotating disk. A driving block is threaded on the outer side of the screw. A connecting plate is fixedly connected to the end of the driving block near the top plate. A slide rail is fixedly connected to the end of the connecting plate near the top plate.

[0011] As a preferred embodiment of the above technical solution, a sliding sleeve is slidably sleeved on the side of the slide rail near the top plate, and a connecting plate is fixedly connected to the end of the sliding sleeve near the top plate. The connecting plate is fixedly connected to the center of one side wall of the top plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are: After the device is started, two servo motors operate synchronously, driving the drive belt via a wheel. The drive belt, through a fixed protrusion at its lower end, drives the printing base and the printing head mounted at its lower end, making a smooth and precise vertical reciprocating motion along the slide rail below the top plate. The synchronous drive of the dual motors ensures balanced force during the pressing and lifting of the printing head, effectively eliminating the problems of jamming, uneven load, and speed fluctuations that are prone to occur with single-motor drives, and reducing defects such as broken lines and incomplete printing in fine line printing.

[0013] Based on the aforementioned beneficial effects, when the overall height of the printing assembly needs to be adjusted according to the thickness of the glass substrate, the operator can rotate the rotating disk. The rotating disk drives the screw to rotate, and the driving block meshing with the screw moves linearly accordingly. The driving block pushes or pulls the slide rail two fixed to it through the connecting plate one. The slide rail two and the sliding sleeve two fixed on the top plate form a sliding pair. The linear motion of the slide rail two is converted into the sliding of the sliding sleeve two along its surface. Due to the small tilt angle of the slide rail two, the printing assembly is driven by the connecting plate two to perform a small and precise lifting and lowering movement along the sliding column in the fixed base. This mechanism realizes stepless fine adjustment of the overall height of the printing assembly, adapts to the printing needs of glass of different specifications, and ensures the adaptability and accuracy of the printing process.

[0016] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0017] Please see Figure 1 As shown, this utility model provides a technical solution: an integrated device for printing and drying conductive silver paste on glass, including a base column 1, a conveying mechanism 2 for conveying glass to various processing areas at the upper end of the base column 1, a printing component 3 for smoothly printing on the glass at one side of the upper end of the conveying mechanism 2, a micro-adjustment lifting mechanism 4 for slightly adjusting the height of the printing component 3 at the center of the upper end of the conveying mechanism 2, and a drying component 5 for drying the conductive silver paste brushed on the glass at the other side of the upper end of the conveying mechanism 2.

[0018] The conveying mechanism 2 is responsible for sequentially transporting the glass substrates to be processed to the printing and drying stations, enabling continuous operation. The printing assembly 3 is responsible for printing conductive silver paste onto the glass surface with high precision and uniformity. The fine-tuning lifting mechanism 4 is used to precisely adjust the overall height of the printing assembly 3 according to the glass thickness or process requirements. The drying assembly 5 cures the printed silver paste lines to ensure their conductivity and adhesion.

[0019] As one implementation method in this embodiment, please refer to Figures 2-4 As shown, the printing component 3 includes a numerical marking ruler 31, which is fixedly connected to the upper end of the conveying component near one side edge. The upper end of the conveying mechanism 2 is symmetrically fixedly connected to fixed bases 32 near both sides edge. Each of the four fixed bases 32 has a sliding column 33 slidably fitted inside. The upper end of the four sliding columns 33 is fixedly connected to a top plate 34, and the lower center of the top plate 34 is fixedly connected to a slide rail 35.

[0020] The numerical marking scale 31 provides a height reference. The fixed base 32 and the slide column 33 form a guide pair, ensuring that the top plate 34 can only be raised and lowered smoothly in the vertical direction, providing a stable support frame for the printing process. The slide rail 35 provides precise guidance for the longitudinal movement of the print head 315.

[0021] As one implementation method in this embodiment, please refer to Figures 2-4 As shown, a fixing plate 36 is fixedly connected to the side wall of the top plate 34 near the numerical scale 31, and a pointer 37 is fixedly connected to the side of the fixing plate 36 near the numerical scale 31.

[0022] The fixed plate 36 and the pointer 37 together constitute the height indication mechanism. The pointer 37 points to the scale of the numerical marking ruler 31, allowing the operator to intuitively and accurately read the current height position of the top plate 34, facilitating initial positioning and height monitoring.

[0023] As one implementation method in this embodiment, please refer to Figures 2-4 As shown, fixed columns 38 are symmetrically fixedly connected to the lower end of the top plate 34 near both sides. Motors 39 are fixedly connected to the two side walls of the two fixed columns 38 that are far apart from each other. Drive wheels 310 are fixedly connected to the output ends of the two motors 39. Transmission belts 311 are meshed with the outer walls of the two drive wheels 310. Transmission wheels 312 are meshed with the ends of the two transmission belts 311 that are far away from the two drive wheels 310.

[0024] Two high-precision servo motors 39 are symmetrically arranged on both sides of the top plate 34. The motors 39 drive the transmission belt 311 through the drive wheel 310. The transmission wheel 312 at the other end of the transmission belt 311 serves the dual function of tensioning and transmission. This dual-side synchronous drive design effectively avoids the problems of uneven load, jamming, or uneven speed that may occur when driven by a single motor 39.

[0025] As one implementation method in this embodiment, please refer to Figures 2-4 As shown, fixed protrusions 313 are symmetrically fixedly connected to the lower outer sides of the two transmission belts 311. A printing base 314 is fixedly connected between the two sets of fixed protrusions 313. A printing head 315 is fixedly connected to the lower center of the printing base 314. A sliding sleeve 316 is fixedly connected to the upper center of the printing base 314.

[0026] The fixed protrusion 313 transmits the motion of the transmission belt 311 to the printing base 314. The printing base 314 is the carrier for mounting the printing head 315. The sliding sleeve 316 cooperates with the slide rail 35 on the top plate 34 to form a sliding pair, ensuring that the printing base 314 and the printing head 315 on it can make smooth and precise vertical movements strictly along the trajectory determined by the slide rail 35 under the drive of the motor 39, preventing wobbling.

[0027] As one implementation method in this embodiment, please refer to Figure 5 As shown, the fine-tuning lifting mechanism 4 includes a second fixed plate 41, which is symmetrically fixedly connected to the upper end of the conveying mechanism 2 on both sides. One side of the second fixed plate 41 is fixedly connected to a rotating disk 42. The output shaft of the rotating disk 42 is fixedly connected to a screw 43. A driving block 44 is threaded on the outer side of the screw 43. A connecting plate 45 is fixedly connected to the end of the driving block 44 near the top plate 34. A slide rail 46 is fixedly connected to the end of the connecting plate 45 near the top plate 34.

[0028] The rotating disk 42 manually drives the screw 43 to rotate, converting the rotational motion of the screw 43 into the linear motion of the driving block 44, which in turn drives the connecting plate 45 and the slide rail 46 to move synchronously. The slide rail 46 is set at an inclined angle on one side of the connecting plate 45.

[0029] As one implementation method in this embodiment, please refer to Figure 5 As shown, a sliding sleeve 47 is slidably fitted on the side of the slide rail 46 near the top plate 34. A connecting plate 48 is fixedly connected to one end of the sliding sleeve 47 near the top plate 34. The connecting plate 48 is fixedly connected to the center of one side wall of the top plate 34.

[0030] Connecting plate 48 fixes sliding sleeve 47 to top plate 34. When rotating disk 42 drives screw 43 to rotate, it moves block 44 and slides sliding sleeve 47 on the outside of slide rail 46 through slide rail 46. Then, through connecting plate 48, it drives the entire top plate 34 and printing assembly 3 to make fine adjustment lifting and lowering movements, so as to achieve fine adjustment of printing height.

[0031] Working principle: After the device is started, the two servo motors 39 run synchronously, driving the transmission belt 311 through the drive wheel 310. The transmission belt 311 drives the printing base 314 and the printing head 315 installed at its lower end through the fixed protrusion 313 at its lower end, making stable and precise vertical reciprocating motion along the slide rail 35 below the top plate 34. The synchronous drive of the two motors 39 ensures that the printing head 315 is subjected to balanced force during the pressing and lifting process, effectively eliminating the problems of jamming, uneven load and speed fluctuation that are easy to occur when driven by a single motor 39, and reducing defects such as broken lines and false printing in fine line printing.

[0032] When the overall height of the printing assembly 3 needs to be adjusted according to the thickness of the glass substrate, the operator can rotate the rotating disk 42. The rotating disk 42 drives the screw 43 to rotate, and the driving block 44, which meshes with the screw 43, moves linearly accordingly. The driving block 44 pushes or pulls the slide rail 46 fixed to it through the connecting plate 45. The slide rail 46 and the sliding sleeve 47 fixed on the top plate 34 form a sliding pair. The linear motion of the slide rail 46 is converted into the sliding of the sliding sleeve 47 along its surface. Due to the small tilt angle of the slide rail 46, the connecting plate 48 drives the printing assembly 3 to make small and precise lifting movements along the sliding column 33 in the fixed base 32. This mechanism realizes stepless fine adjustment of the overall height of the printing assembly 3, adapts to the printing needs of different glass specifications, and ensures the adaptability and accuracy of the printing process.

[0033] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
