Description

Technical Field

[0001] This utility model relates to the field of screen printing technology, specifically a screen printing surface coating treatment device. Background Technology

[0002] Screen printing is a process used in the mass production of solar cells. Its purpose is to press a conductive paste containing metal onto a silicon wafer through the mesh of a screen to form circuits and / or electrodes. The screen printing stencil for solar cells generally uses steel wire mesh as the material for the printing area, while the perimeter is composited with polyester mesh to give the steel wire mesh a certain degree of resilience to achieve the printing purpose. During the manufacturing process of solar cell printing stencils, a certain thickness of photosensitive paste needs to be sprayed onto the surface of the stencil.

[0003] Chinese patent CN219631827U discloses a solar screen coating device, including a worktable. A fixed frame is installed on the top of the worktable. A first motor is fixedly installed on the top of one side of the fixed frame, and a second motor is fixedly installed in the middle of one side of the worktable. Support rods are slidably installed on both sides of the top of the worktable, and an L-shaped placement plate is rotatably installed on the adjacent side of the support rods. In this invention, by starting a third motor, the first screw is driven to rotate, thereby driving the movable plate and rack to move inside the fixed rod. This simultaneously drives the L-shaped placement plate connected to the gear to rotate. When the movable plate moves to the top of one end of the fixed rod, the screen fixed on the L-shaped placement plate rotates 180°. At this time, the other side of the screen can be coated, thus achieving the effect of coating the back of the screen without removing the screen. This effectively improves work efficiency and saves labor costs. As can be seen from the above patent, when spraying solar screens, the screen needs to be removed and reinstalled to coat the reverse side of the screen, thus reducing the overall coating efficiency. Therefore, we propose a screen surface spraying treatment device. Utility Model Content

[0004] The purpose of this invention is to provide a screen coating treatment device to solve the problem in the prior art that the screen needs to be removed and reinstalled before the reverse side of the screen can be coated, which reduces the overall coating efficiency.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a screen printing plate surface spraying treatment device, including a base plate, support rods fixed at the four top corners of the base plate, a top plate fixed at the top of the support rods, a moving component connected to the top of the top plate, a coating component connected to the top of the top plate, a flipping mechanism provided on the base plate, an installation frame connected inside the flipping mechanism, and a fixing mechanism provided on the inner side of the installation frame;

[0006] The flipping mechanism includes mounting plates symmetrically fixed to the top of the base plate. A rotating shaft is rotatably inserted through the top of one side of the mounting plate. A worm gear is fixed to one end of one of the rotating shafts. A fixing plate is symmetrically fixed to one side of the mounting plate. A worm gear is rotatably inserted through the inner side of the fixing plate. A drive motor is fixed to one side of one of the fixing plates.

[0007] Preferably, the flipping mechanism further includes symmetrical through holes on one side of the mounting plate, a rod slidingly passing through one side of the worm gear, a pull plate fixed to one end of the rod, and a return spring fixed to one side of the pull plate.

[0008] Preferably, the output shaft end of the drive motor is fixedly connected to one end of the worm, and the input end of the drive motor is electrically connected to the output end of an external power supply. The drive motor drives the worm to rotate, thereby causing the worm wheel to rotate.

[0009] Preferably, the nozzle of the coating assembly is connected to the bottom of the moving assembly, a placement platform is placed on the top of the base plate to facilitate the support and placement of the screen, and the worm gear is meshed with the worm wheel.

[0010] Preferably, the return spring is sleeved on the outside of the insertion rod, and the end of the return spring is fixed to one side of the worm gear, so as to facilitate the insertion rod to return to its original position.

[0011] Preferably, the fixing mechanism includes a through groove formed on one side of the mounting frame, a sliding rod fixed at the middle of both sides of the through groove, a slider sliding on the outer side of the sliding rod, a clamp fixed on the opposite side of the two sliders, a connecting rod rotatably connected to one side of the slider via a connecting shaft, a fixing frame fixed on one side of the mounting frame, a rotating motor fixed at the middle of the inner side of the fixing frame, and a turntable fixed at the end of the output shaft of the rotating motor.

[0012] Preferably, the input end of the rotary motor is electrically connected to the output end of an external power supply, the slider is located inside the through slot, and the connecting rod rotates on one side of the turntable via a connecting shaft, causing the connecting rod to deflect when the turntable rotates.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. This application utilizes a flipping mechanism. Pulling the pull plate moves the insert rod out of the insertion hole, simultaneously stretching the return spring. By starting the drive motor, the worm gear rotates, causing the worm wheel to rotate, which in turn rotates the shaft, causing the mounting frame to deflect. When the mounting frame is flipped 180 degrees, the drive motor is turned off, the pull plate is loosened, and the return spring resets the insert rod, allowing it to be embedded in the insertion hole. This limits the movement of the worm wheel, facilitating the flipping of the screen and avoiding the need to remove and reinstall the screen. This facilitates double-sided coating and improves overall coating efficiency.

[0015] 2. In this application, by setting up a fixing mechanism, the placement platform is placed on the base plate, and then the screen is placed on the placement platform, so that the screen is located inside the mounting frame. By starting the rotating motor, the turntable is driven to rotate, causing the connecting rod to deflect, thereby causing the sliders to move closer to each other, and causing the clamping plates to move closer to each other, thus fixing the screen and ensuring stability during the flipping process. At the same time, it is easy to adjust the distance between the two clamping plates, which is convenient for clamping different screens and improving the applicability of the device.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Figures 1-5As shown, this utility model provides a technical solution for a screen printing surface spraying treatment device, including a base plate 100, support rods 200 fixed at the four corners of the top of the base plate 100, a top plate 300 fixed at the top of the support rods 200, a moving component 400 connected to the top of the top plate 300, a coating component 500 connected to the top of the top plate 300, a flipping mechanism 600 provided on the base plate 100, an installation frame 700 connected inside the flipping mechanism 600, and a fixing mechanism 800 provided on the inner side of the installation frame 700.

[0024] Please see Figure 2 and Figure 3 The flipping mechanism 600 includes mounting plates 610 symmetrically fixed to the top of the base plate 100. A rotating shaft 620 is rotatably driven through one side of the top of the mounting plate 610. A worm gear 630 is fixed to one end of the rotating shaft 620. A fixing plate 640 is symmetrically fixed to one side of the mounting plate 610. A worm gear 650 is rotatably driven through the inner side of the fixing plate 640. A drive motor 660 is fixed to one side of the fixing plate 640. The flipping mechanism 600 also includes insertion holes 670 symmetrically opened through one side of the mounting plate 610. A sliding rod 680 is slidably driven through one side of the worm gear 630. A pull plate 690 is fixed to one end of the insertion rod 680. A return spring 691 is fixed to one side of the pull plate 690. The output shaft end of the drive motor 660 is fixedly connected to one end of the worm gear 650, and the input end of the drive motor 660 is electrically connected to the output end of an external power supply. The nozzle of the coating assembly 500 is connected to the bottom of the moving assembly 400. The base plate 100 has a placement platform 110 on top, and the worm gear 650 is meshed with the worm wheel 630. A return spring 691 is sleeved on the outside of the insertion rod 680, and the end of the return spring 691 is fixed to one side of the worm wheel 630. Using the flipping mechanism 600, pulling the pull plate 690 moves the insertion rod 680 out of the insertion hole 670, simultaneously stretching the return spring 691. The start of the drive motor 660 drives the worm gear 650 to rotate, causing... The worm gear 630 rotates, causing the shaft 620 to rotate and the mounting frame 700 to deflect. When the mounting frame 700 rotates 180 degrees, the drive motor 660 is turned off, the pull plate 690 is loosened, and the reset spring 691 resets the insertion rod 680 into the insertion hole 670, limiting the worm gear 630. This facilitates the flipping of the screen, avoiding the need to remove the screen, flip it over, and reinstall it, thus facilitating double-sided coating and improving overall coating efficiency.

[0025] Please see Figure 4 and Figure 5The fixing mechanism 800 includes a through groove 810 formed on one side of the mounting frame 700. Slide rods 820 are fixed to the middle of both sides of the through groove 810. Slider blocks 830 slide on the outer sides of the slide rods 820. Clamping plates 840 are fixed to the opposite sides of the two sliders 830. A connecting rod 850 rotates on one side of the slider 830 via a connecting shaft. A fixing frame 860 is fixed to one side of the mounting frame 700. A rotary motor 870 is fixed to the middle of the inner side of the fixing frame 860. A turntable 880 is fixed to the end of the output shaft of the rotary motor 870. The input end of the rotary motor 870 is electrically connected to the output end of an external power supply. The slider 830 is located in the through groove 810. Inside the 10, the connecting rod 850 rotates on one side of the turntable 880 via the connecting shaft. Utilizing the fixing mechanism 800, the placement platform 110 is placed on the base plate 100, and then the screen is placed on the placement platform 110, so that the screen is located inside the mounting frame 700. By starting the rotating motor 870, the turntable 880 is driven to rotate, causing the connecting rod 850 to deflect, thereby causing the sliders 830 to move closer together, which in turn causes the clamping plates 840 to move closer together, fixing the screen and ensuring stability during the flipping process. At the same time, it is easy to adjust the distance between the two clamping plates 840 to easily clamp different screens and improve the applicability of the device.

[0026] Specifically, the moving component 400 and the coating component 500 have been specifically disclosed in the prior art.

[0027] In use, this invention works as follows: During coating, the placement platform 110 is first placed on top of the base plate 100, and the screen is placed on the placement platform 110, so that the screen is located inside the mounting frame 700. By starting the rotating motor 870, the turntable 880 is rotated, causing the connecting rod 850 to deflect, thereby bringing the sliders 830 closer together, which in turn brings the clamping plates 840 closer together, fixing the screen. Then, the placement platform 110 is removed from the base plate 100, and the moving component 400 and coating component 500 are started, causing the coating component 500 to move and spray the screen. When it is necessary to spray the other side, the moving component 400 is turned off. The moving assembly 400 and the coating assembly 500 pull the pull plate 690, causing the insert rod 680 to move out of the insertion hole 670. At the same time, the return spring 691 is stretched. By starting the drive motor 660, the worm gear 650 is driven to rotate, causing the worm wheel 630 to rotate, which in turn causes the rotating shaft 620 to rotate, causing the mounting frame 700 to deflect. When the mounting frame 700 rotates 180 degrees, the drive motor 660 is turned off, the pull plate 690 is loosened, and the return spring 691 resets, causing the insert rod 680 to be embedded in the insertion hole 670, limiting the worm wheel 630, flipping the screen over, and restarting the moving assembly 400 and the coating assembly 500 to perform spraying.
