Description

Technical Field

[0001] The present invention relates to the technical field of printing stencils, and specifically to a quality detection device for solar cell printing stencils. Background Art

[0002] The solar cell printing stencil is one of the key components in the manufacturing process of solar cells. During the manufacturing process of solar cells, the printing stencil is mainly used in screen printing technology, which is a process of printing a paste onto a crystalline silicon wafer through a stencil with a specific pattern. The accuracy and quality of the printing stencil directly affect the performance and efficiency of solar cells.

[0003] In the prior art, after the solar cell printing stencil is detected, it needs to be encapsulated in time to avoid pollution and damage to the surface of the printing stencil by the external environment. However, in the actual encapsulation process, the printing stencil generally needs to be transported. Since the printing stencil is large in size, manual encapsulation is required, which not only reduces the encapsulation efficiency but also increases the possible human errors during the encapsulation process, resulting in unstable encapsulation quality. Therefore, the present invention provides a quality detection device for solar cell printing stencils. Summary of the Invention

[0004] The purpose of the present invention is to provide a quality detection device for solar cell printing stencils to solve the problems raised in the above background art.

[0005] The technical solution of the present invention is: a quality detection device for a solar cell printing screen plate, including an installation control box, a printing screen plate, and a transport conveyor belt. Inside the installation control box, there is a fixedly connected installation frame, and the installation frame is installed on the top of the transport conveyor belt. Inside the installation control box, there is a fixedly connected laser detection frame, and the laser detection frame is installed inside the installation frame. On the top of the installation frame, there are two fixedly connected top mounting blocks, and a storage roller is rotatably connected between the two top mounting blocks. Inside the installation frame, there are two fixedly connected liquid-attaching clamping blocks, and a liquid-attaching cylinder is fixedly connected between the two liquid-attaching clamping blocks. Inside the liquid-attaching cylinder, there is a rotatably connected toothed roller, and a rotating shaft is fixedly connected to the inside of the toothed roller. One end of the rotating shaft penetrates through the liquid-attaching cylinder and the end of the rotating shaft is fixedly connected to the inside of the installation control box. On the outside of the liquid-attaching cylinder, there are two long grooves. On the top of the installation frame, there is a fixedly connected protective top plate, and a liquid storage box is fixedly connected to the top of the protective top plate. A liquid flow frame is fixedly connected to the bottom of the liquid storage box, and a liquid guiding frame is fixedly connected to the bottom of the liquid flow frame. The liquid guiding frame is communicated with one of the long grooves on the outside of the liquid-attaching cylinder. Inside the two liquid-attaching clamping blocks, there are two rotatably connected liquid-attaching hydraulic shafts, and the liquid-attaching hydraulic shafts are in close contact with the liquid-attaching cylinder. Inside the installation frame, there is a fixedly connected film laminating clamping block, and two film laminating rollers are rotatably connected to the inside of the film laminating clamping block. On the conveying surface of the installation control box, there are two fixedly connected transport clamping blocks, and on the adjacent sides of the two transport clamping blocks, there are slidingly clamped transport sliders. A transport bottom plate is fixedly connected between the two transport sliders, and the printing screen plate is movably clamped between the two transport clamping blocks, and the printing screen plate is placed on the top of the transport bottom plate. On one side of the laser detection frame, there is a fixedly connected liquid separation plate; When in use: insert the transport bottom plate into the inside of the two transport clamping blocks through the transport sliders, place the printing screen plate on the top of the transport bottom plate and transport it through the transport conveyor belt, so that the printing screen plate moves while being detected under the bottom of the laser detection frame. The liquid storage box stores the film laminating liquid, and the film laminating liquid flows into the long groove at the top of the liquid-attaching cylinder through the liquid flow frame and the liquid guiding frame. While the printing screen plate is being transported, the installation control box controls the rotation of the rotating shaft to make the toothed roller rotate, and transports the film laminating liquid through the tooth grooves on the outside of the toothed roller, so that the film laminating liquid flows out through the long groove on the side of the liquid-attaching cylinder. Initially, the protective film is stored on the outside of the storage roller. The protective film passes between the liquid-attaching hydraulic shaft and the liquid-attaching cylinder, so that one side of the protective film is in close contact with the long groove on the side of the liquid-attaching cylinder, and the film laminating liquid flows to the side of the protective film. Then, make the protective film be pressed on the top surface of the printing screen plate through the two film laminating rollers to complete film laminating.

[0006] Preferably, two first mounting boxes are fixedly connected to the side of the mounting frame, second mounting boxes are fixedly connected to the sides of the two first mounting boxes, fixing columns are fixedly connected to the inner sides of the first mounting boxes and the second mounting boxes, a pull-down spring is movably sleeved on the outer side of the fixing column, a movable block is slidably clamped at the top of the fixing column, the top of the pull-down spring is fixedly connected to the movable block, a pressing roller is fixedly connected to the inner sides of the movable blocks at the tops of the two first mounting boxes, a guiding trapezoidal column is fixedly connected to the inner sides of the movable blocks at the tops of the two first mounting boxes, a cutting knife is fixedly connected to the inner sides of the movable blocks at the tops of the two first mounting boxes, a pressing cylinder is rotatably connected to the side of the pressing roller, the guiding trapezoidal column is located between the mounting frame and the pressing roller, the cutting knife is located on the other side of the pressing roller, a connecting block is fixedly connected to the side of the mounting frame, a supporting bottom block is fixedly connected to the side of the connecting block, the supporting bottom block is located at the bottom of the pressing cylinder, mounting side plates are fixedly connected to the inner sides of the movable blocks at the tops of the second mounting boxes, a connecting mounting block is fixedly connected to the inner sides of the two mounting side plates, a hydraulic guiding plate is fixedly connected to the inner sides of the two connecting mounting blocks, liquid guiding blocks are fixedly connected to the bottoms of both ends of the hydraulic guiding plate, and a waste liquid box is fixedly connected to the bottom of the liquid guiding block; When in use: After the film covering is completed, one side of the transportation clamping block is an arc surface. When the transportation clamping block transports to the bottom of the guiding trapezoidal column, it will push the bottom inclined surface of the guiding trapezoidal column through the arc surface, causing the guiding trapezoidal column to move upward, pulling the movable block inside the first mounting box to move upward as a whole, pressing the pressing cylinder tightly against the protective film. When the printing screen plate completely passes through, it is pulled by the pull-down spring to move the movable block downward, pulling the cutting knife downward to cut off the uncut protective film, and pressing one end of the protective film against the bottom of the pressing cylinder, so that when the next film covering is carried out, this end of the fixed film is convenient for the next film covering. While completing the above, the printing screen plate passes through the bottom of the hydraulic guiding plate. The hydraulic guiding plate also passes through the arc surface of the transportation clamping block and is pushed upward. At the same time, it is pulled by the pull-down spring to make the hydraulic guiding plate closely adhere to the top of the protective film for extrusion, so that the bubbles and excessive film covering liquid between the protective film and the printing screen plate are pushed by the hydraulic guiding plate to the inside of the liquid guiding blocks on both sides, and the excessive film covering liquid flows into the inside of the waste liquid box.

[0007] The present invention provides a quality inspection device for a solar cell printing screen plate through improvement. Compared with the prior art, it has the following improvements and advantages:

[0008] First: For a solar cell printing screen quality detection device of the present invention, the transportation bottom plate is inserted into the inner sides of two transportation clamping blocks through transportation sliders. The printing screen is placed on the top of the transportation bottom plate and transmitted through a transportation conveyor belt, so that the printing screen is detected while moving through the bottom of the laser detection frame. A liquid storage box stores a film coating liquid, and the film coating liquid flows into the long groove at the top of the liquid attachment cylinder through a liquid flow frame and a liquid guide frame. While the printing screen is being transmitted, the installation control box controls the rotation of the rotating shaft to make the toothed roller rotate, and the film coating liquid is transported through the tooth grooves on the outer side of the toothed roller, so that the film coating liquid flows out through the long groove on the side of the liquid attachment cylinder. Initially, the protective film is stored on the outer side of the storage roller. The protective film passes between the liquid attachment hydraulic shaft and the liquid attachment cylinder, so that one side of the protective film is closely attached to the long groove on the side of the liquid attachment cylinder, and the film coating liquid flows to the side of the protective film. After that, the protective film is pressed on the top surface of the printing screen through two film coating rollers to complete film coating;

[0009] Second: For a solar cell printing screen quality detection device of the present invention, after film coating is completed, one side of the transportation clamping block is an arc surface. When the transportation clamping block transports to the bottom of the guiding trapezoidal column, it will push the bottom inclined surface of the guiding trapezoidal column through the arc surface, causing the guiding trapezoidal column to move upward and pulling the movable block inside the first installation box to move upward as a whole, so that the pressing cylinder tightly presses on the protective film. When the printing screen completely passes through, it is pulled by a downward pulling spring to make the movable block move downward and pull the cutting knife downward to cut off the uncut protective film, and one end of the protective film is pressed on the bottom of the pressing cylinder, so that when film coating is carried out next time, the fixed film at this end is convenient for the next film coating. While the above is completed, the printing screen passes through the bottom of the hydraulic guiding plate. The hydraulic guiding plate also moves upward through the arc surface of the transportation clamping block and is pulled by a downward pulling spring at the same time, so that the hydraulic guiding plate is closely attached to the top of the protective film for extrusion, so that the bubbles and excessive film coating liquid between the protective film and the printing screen are pushed to the inside of the liquid guiding blocks on both sides by the hydraulic guiding plate, and the excessive film coating liquid flows into the inside of the waste liquid box;

[0010] Summary: For a solar cell printing screen quality detection device of the present invention, during the film coating process, the device precisely controls the flow and distribution of the film coating liquid to ensure that the protective film can evenly and completely cover the surface of the target object, thereby improving the film coating quality and efficiency. At the same time, the structure of the device is reasonably designed and easy to operate, which can reduce errors and waste during the operation process, improve production efficiency, and perform film coating immediately after detection to avoid external contamination and damage to the printing screen.

Between the two liquid-attaching clamp blocks 15, there is a fixedly connected liquid-attaching cylinder 16. Inside the liquid-attaching cylinder 16, there is a rotatably connected toothed roller 17. Inside the toothed roller 17, there is a fixedly connected rotating shaft 18. One end of the rotating shaft 18 penetrates through the liquid-attaching cylinder 16 and the end of the rotating shaft 18 is fixedly connected inside the installation control box 1. On the outside of the liquid-attaching cylinder 16, there are two long grooves. On the top of the installation frame 2, there is a fixedly connected protective top plate 3. On the top of the protective top plate 3, there is a fixedly connected liquid storage box 12. At the bottom of the liquid storage box 12, there is a fixedly connected liquid flow frame 13.

Then, press the protective film on the top surface of the printing screen plate 9 through the two film laminating rollers 36 to complete film laminating.

[0030] Further, two first mounting boxes 19 are fixedly connected to the side of the mounting frame 2. Second mounting boxes 38 are fixedly connected to the sides of the two first mounting boxes 19. Fixed columns 20 are fixedly connected to the inner sides of the first mounting boxes 19 and the second mounting boxes 38. A pull-down spring 22 is movably sleeved on the outer side of the fixed column 20. A movable block 21 is slidably clamped at the top of the fixed column 20.

The cutting knife 28 is located on the other side of the pressing roller 25. A connecting block 23 is fixedly connected to the side of the mounting frame 2. A supporting bottom block 24 is fixedly connected to the side of the connecting block 23. The supporting bottom block 24 is located at the bottom of the pressing cylinder 26. Mounting side plates 29 are fixedly connected to the inner sides of the movable blocks 21 at the tops of the second mounting boxes 38. A connecting mounting block 30 is fixedly connected to the inner sides of the two mounting side plates 29. A guiding hydraulic plate 31 is fixedly connected to the inner sides of the two connecting mounting blocks 30. Liquid guiding blocks 32 are fixedly connected to the bottoms of both ends of the guiding hydraulic plate 31. A waste liquid box 33 is fixedly connected to the bottom of the liquid guiding block 32; When in use: After the film covering is completed, one side of the transport clamping block 6 is an arc surface. When the transport clamping block 6 transports to the bottom of the guiding trapezoidal column 27, it will push the bottom inclined surface of the guiding trapezoidal column 27 through the arc surface, causing the guiding trapezoidal column 27 to move upward, pulling the whole movable block 21 inside the first mounting box 19 upward, so that the pressing cylinder 26 tightly presses on the protective film. When the printing screen plate 9 completely passes through, it is pulled by the pull-down spring 22, causing the movable block 21 to move downward, pulling the cutting knife 28 downward, cutting off the uncut protective film, and pressing one end of the protective film against the bottom of the pressing cylinder 26, so that when the next film covering is carried out, the fixed film at this end is convenient for the next film covering. While completing the above, the printing screen plate 9 passes through the bottom of the guiding hydraulic plate 31. The guiding hydraulic plate 31 is also pushed upward through the arc surface of the transport clamping block 6. At the same time, it is pulled by the pull-down spring 22, causing the guiding hydraulic plate 31 to closely adhere to the top of the protective film for extrusion, so that the bubbles and excessive film covering liquid between the protective film and the printing screen plate 9 are pushed to the inside of the liquid guiding blocks 32 on both sides by the guiding hydraulic plate 31, and the excessive film covering liquid flows into the inside of the waste liquid box 33.

[0031] Working principle: When in use: Insert the transportation bottom plate 8 into the inner sides of two transportation clamping blocks 6 through the transportation sliders 7. Place the printing stencil 9 on the top of the transportation bottom plate 8 and transport it through the transportation conveyor belt 34, so that the printing stencil 9 is detected while moving through the bottom of the laser detection frame 4. The liquid storage box 12 stores the laminating liquid, and the laminating liquid flows into the long groove at the top of the liquid attachment cylinder 16 through the liquid flow frame 13 and the liquid guide frame 14. While the printing stencil 9 is being transported, the control box 1 is installed to control the rotation of the rotating shaft 18, so that the toothed roller 17 rotates, and the laminating liquid is transported through the tooth grooves on the outer side of the toothed roller 17, so that the laminating liquid flows out through the long groove on the side of the liquid attachment cylinder 16. Initially, the protective film is stored on the outer side of the storage roller 11. The protective film passes between the liquid attachment hydraulic shaft 37 and the liquid attachment cylinder 16, so that one side of the protective film is in close contact with the long groove on the side of the liquid attachment cylinder 16, and the laminating liquid flows to the side of the protective film. Then, the protective film is pressed on the top surface of the printing stencil 9 through two laminating rollers 36 to complete the lamination. After the lamination is completed, one side of the transportation clamping block 6 is an arc surface. When the transportation clamping block 6 is transported to the bottom of the guiding trapezoidal column 27, it will push the bottom inclined surface of the guiding trapezoidal column 27 through the arc surface, so that the guiding trapezoidal column 27 moves upward, pulling the movable block 21 inside the first installation box 19 to move upward as a whole, so that the pressing cylinder 26 tightly presses on the protective film. When the printing stencil 9 has completely passed through, it is pulled by the downward pull spring 22, so that the movable block 21 moves downward, pulling the cutting knife 28 downward to cut off the uncut protective film, and pressing one end of the protective film on the bottom of the pressing cylinder 26, so that when laminating next time, this fixed end of the film is convenient for the next lamination. While the above is being completed, the printing stencil 9 passes through the bottom of the liquid guide pressing plate 31. The liquid guide pressing plate 31 is also pushed upward through the arc surface of the transportation clamping block 6, and at the same time is pulled by the downward pull spring 22, so that the liquid guide pressing plate 31 closely adheres to the top of the protective film and squeezes, so that the bubbles and excessive laminating liquid between the protective film and the printing stencil 9 are pushed to the inside of the liquid guide blocks 32 on both sides by the liquid guide pressing plate 31, and the excessive laminating liquid flows into the inside of the waste liquid box 33.
