Abstract
Description
Technical Field
[0001] This utility model relates to the field of screen printing technology, and more specifically, to a printing platform for screen printing. Background Technology
[0002] A circuit board, also known as a printed circuit board, is a core component in electronic equipment that provides mechanical assembly support and electrical connections for various electronic systems. During the production process, circuit boards are formed by screen printing to create circuit patterns, providing a foundation for the installation and electrical connection of electronic components and ensuring the normal operation of the circuit.
[0003] Currently, the screen is the most important component in screen printing. It is the key to controlling ink flow and printing thickness, and also determines the durability of the screen. The screen has evenly distributed mesh openings, and its mesh count determines the size of the mesh openings and the fineness of the printed pattern. During printing, ink is placed at one end of the screen, and a certain pressure is applied and moved by a squeegee, so that the ink passes through the mesh openings of the screen under pressure and is transferred to the surface of the circuit board located below the screen.
[0004] However, after screen printing, circuit boards require other processing operations, and the circuit boards will be transferred from one station to another. During the transfer process, the circuit boards need to be removed from the placement table and then transferred again. This increases the turnaround time and affects the circuit board processing efficiency. In addition, during the transfer process, the circuit boards may be damaged due to factors such as static electricity and friction. A screen printing platform is proposed to improve the existing problems. Utility Model Content
[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a printing platform for screen printing.
[0006] To achieve the above objectives, the present invention provides the following technical solution:
[0007] A printing platform for screen printing includes a printing component, a platform component disposed on the top of the printing component, and a collecting component disposed on one side of the platform component.
[0008] The printing assembly includes a worktable, which is hollow inside. Four sets of support columns are installed through the top of the worktable. A sliding plate is installed above the worktable and is slidably connected to the support columns. A first fixing plate is installed above the sliding plate and is fixedly connected to the support columns. A second cylinder is installed on the top of the first fixing plate, and the output end of the second cylinder is connected to the sliding plate.
[0009] The platform component includes a fixing plate, and two sets of fourth cylinders are symmetrically arranged on the top of the fixing plate. A placement platform is arranged in the middle of the two sets of fourth cylinders, and the placement platform is used to place the workpiece to be printed.
[0010] The collecting assembly includes a connecting plate disposed on one side of the fixed plate. The connecting plate is used to assist in collecting the workpiece after printing. A collecting groove is provided at the bottom of the connecting plate.
[0011] By adopting the above technical solution, after the circuit board printing is completed, the fixing plate can be tilted. At this time, the placement platform and the circuit board slide together along the connecting plate to the collection tank. If further processing is required, the placement platform and the circuit board can be transported together, eliminating the need to remove and transfer the circuit board. The placement platform with the circuit board can be directly transported to the next process, reducing turnaround time. At the same time, the placement platform also provides a certain degree of protection for the circuit during the transfer process. In addition, both the connecting plate and the collection tank are equipped with antistatic foam. Antistatic foam is a packaging material with cushioning properties. Its internal pore structure can effectively absorb the energy generated by the collision and provide cushioning protection during the slide of the circuit board. At the same time, its antistatic properties can prevent static electricity from damaging the circuit board.
[0012] The present invention is further configured such that: the printing assembly includes a first cylinder, the output end of the first cylinder is connected to a mounting plate, and a third cylinder is provided on one side of the mounting plate.
[0013] The present invention is further configured such that: the output end of the third cylinder is connected to a second fixing plate, a fixing frame is provided below the second fixing plate, and the fixing frame is connected to the second fixing plate by a fixing rod.
[0014] The present invention is further configured such that: a scraper is connected to the side of the fixing frame away from the second fixing plate, a screen printing plate is provided below the scraper, and the screen printing plate is fixedly connected to the sliding plate.
[0015] By adopting the above technical solution, and by setting up a device that uses a first cylinder, a third cylinder and a scraper in conjunction, ink can be transferred through the mesh of the screen to the surface of the circuit board, thereby achieving printing on the circuit board.
[0016] The present invention is further configured such that: the platform component includes a slide mechanism, the slide mechanism is installed inside the workbench, the top of the slide mechanism is provided with a column, the column is provided at the bottom of the fixed plate, and the column is hinged to the fixed plate.
[0017] The present invention is further configured such that: a fifth cylinder is provided on one side of the column, the fifth cylinder is located at the bottom of the fixed plate, and the output end of the fifth cylinder is hinged to the fixed plate.
[0018] By adopting the above technical solution, after the circuit board printing is completed, the fixing plate is activated, the placement platform is released, and the placement platform is in a movable state. Then the fifth cylinder is activated. Since the fifth cylinder is hinged to the fixing plate and the fixing plate is hinged to the column, the fixing plate will tilt when the fifth cylinder moves upward. At this time, the placement platform carrying the circuit board slides from the connecting plate to the position of the collection tank. If subsequent processing work is to be carried out, the placement platform and the circuit board can be transferred together.
[0019] In summary, this application includes at least one of the following beneficial technical effects:
[0020] 1. By setting up connecting plates and collection slots, a collection space is provided for the placement platform and the collection of circuit boards, eliminating the steps of removing and transferring circuit boards. The placement platform with circuit boards can be directly transported to the next process, reducing turnaround time. In addition, the surfaces of the connecting plates and collection slots are equipped with antistatic foam. Antistatic foam is a packaging material with cushioning properties. Its internal pore structure can effectively absorb the energy generated by collisions and provide cushioning protection during the slippage of circuit boards. At the same time, its antistatic properties can prevent static electricity from damaging the circuit boards.
[0021] 2. By setting up a device that uses a first cylinder, a third cylinder and a scraper in conjunction, ink is transferred through the mesh of the screen to the surface of the circuit board, thus achieving printing on the circuit board.
[0022] 3. By setting up the fifth cylinder, the fixing plate, and the column in cooperation, a foldable structure is achieved. The folding structure satisfies the condition that the placement platform slides down from inside the fixing plate, and finally achieves the effect of the placement platform and the circuit board sliding down into the collection tank together.

[0031] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. The present invention will now be described in detail with reference to the accompanying drawings and embodiments.
[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meaning as commonly understood by one of ordinary skill in the art to which this application pertains.
[0033] Example 1, please refer to Figure 1-5 The present invention provides the following technical solution:
[0034] See Figure 1 A printing platform for screen printing includes a printing component 1, a platform component 2 disposed on the top of the printing component 1, and a collecting component 3 disposed on one side of the platform component 2.
[0035] See Figure 2-4 The printing assembly 1 includes a worktable 11, which is hollow inside. Four sets of support columns 12 are installed through the top of the worktable 11. A sliding plate 13 is installed above the worktable 11 and is slidably connected to the support columns 12. A first fixing plate 14 is installed above the sliding plate 13 and is fixedly connected to the support columns 12. A second cylinder 102 is installed on the top of the first fixing plate 14 and the output end of the second cylinder 102 is connected to the sliding plate 13.
[0036] See Figure 2-4 The platform component 2 includes a fixing plate 21. Two sets of fourth cylinders 22 are symmetrically arranged on the top of the fixing plate 21. A placement platform 23 is arranged in the middle of the two sets of fourth cylinders 22. The placement platform 23 is used to place the workpiece to be printed.
[0037] See Figure 2The collecting component 3 includes a connecting plate 31, which is disposed on one side of the fixed plate 21. The connecting plate 31 is used to assist in collecting the workpiece after printing. A collecting groove 32 is provided at the bottom of the connecting plate 31. In actual production, the workpiece is a circuit board.
[0038] After the circuit board printing is completed, the fixing plate 21 can be tilted. At this time, the placement platform 23 and the circuit board slide down along the connecting plate 31 to the position of the collection groove 32. If further processing is to be carried out, the placement platform 23 and the circuit board can be transferred together, which can eliminate the steps of removing and transferring the circuit board. The placement platform with the circuit board can be directly transported to the next process, reducing the turnaround time and improving the processing efficiency of the circuit board. At the same time, the placement platform 23 also provides a certain degree of protection for the circuit during the transfer process, protecting the circuit board itself from damage.
[0039] In addition, both the connecting plate 31 and the collecting groove 32 are provided with antistatic foam. Antistatic foam is a packaging material with cushioning properties. Its internal pore structure can effectively absorb the energy generated by the collision and provide cushioning protection during the slide of the circuit board. At the same time, its antistatic properties can prevent static electricity from damaging the circuit board, increase the pass rate of the circuit board and improve the production efficiency of the circuit board.
[0040] See Figure 2-4 The printing assembly 1 includes a first cylinder 101. The output end of the first cylinder 101 is connected to a mounting plate 19. Two sets of connecting plates are symmetrically arranged on one side of the mounting plate 19. The bottom of the two sets of connecting plates is fixedly connected to the sliding plate 13. The two sets of connecting plates are connected to the mounting plate 19 by a lead screw. The lead screw can slide the two sets of connecting plates. In actual operation, when the sliding plate 13 moves downward, the mounting plate 19 moves downward along with the sliding plate 13. A third cylinder 103 is arranged on one side of the mounting plate 19.
[0041] See Figure 2-4 The output end of the third cylinder 103 is connected to the second fixing plate 15, and a fixing frame 18 is provided below the second fixing plate 15. The fixing frame 18 is connected to the second fixing plate 15 through a fixing rod.
[0042] See Figure 2-4A squeegee 16 is connected to the side of the fixed frame 18 away from the second fixed plate 15. A screen printing plate 17 is set below the squeegee 16. The screen printing plate 17 is fixedly connected to the sliding plate 13. The screen printing plate 17 has uniformly distributed mesh holes inside. The mesh count determines the size of the mesh holes and the fineness of the printed pattern. Printing plates made with 160-mesh nylon screens often have problems such as poor adhesion between the photosensitive film and the screen, thickened and burr-like printed lines, and difficulty in squeegee printing. Printing plates made with 250-mesh nylon screens have improved printing accuracy, less effort in squeegee printing, and smaller burrs. Printing plates made with 360-mesh nylon screens have strong adhesion between the photosensitive film and the screen, less effort in squeegee printing, significantly improved printing accuracy, and neat edges of lines and text. The screen printing plate 17 in this design is made with 360-mesh nylon screens.
[0043] The specific movement flow of printing component 1 is as follows:
[0044] First, the circuit board is placed on the placement platform 23. Then, two sets of fourth cylinders 22 are activated to fix the placement platform 23. At this time, the second cylinder 102 is activated, which moves the sliding plate 13 downwards. Since the sliding plate 13 is fixedly connected to the screen printing plate 17, the screen printing plate 17 moves with the sliding plate 13, and the mounting plate 19 also moves downwards with the sliding plate 13 until the screen printing plate 17 is in contact with the circuit board, that is, the screen printing plate 17 fixes the top of the circuit board. Then, the third cylinder 103 is activated to... The third cylinder 103 makes a fine adjustment to the position of the squeegee 16, then puts ink into the screen 17, and then starts the first cylinder 101. The first cylinder 101 drives the mounting plate 19 to move back and forth in a straight line. At the same time, the squeegee 16 also moves back and forth with the mounting plate 19. During the back and forth movement, the third cylinder 103 applies a certain pressure to the squeegee 16, so that the ink passes through the mesh of the screen 17 under the pressure and is transferred to the surface of the circuit board located below the screen 17, thus completing the printing work of the circuit board.
[0045] See Figure 3-5 Platform component 2 includes a slide mechanism 24, which is installed inside the worktable 11. A column 26 is provided on the top of the slide mechanism 24, and the column 26 is located at the bottom of the fixed plate 21 and is hinged to the fixed plate 21.
[0046] See Figure 3-5 A fifth cylinder 25 is provided on one side of the column 26. The fifth cylinder 25 is located at the bottom of the fixed plate 21, and the output end of the fifth cylinder 25 is hinged to the fixed plate 21.
[0047] After the circuit board printing is completed, the fixing plate 21 is activated, releasing the placement stage 23, which is now in a movable state. Then, the fifth cylinder 25 is activated. Since the fifth cylinder 25 is hinged to the fixing plate 21 and the fixing plate 21 is hinged to the column 26, the fixing plate 21 will tilt when the fifth cylinder 25 moves upward. At this time, the placement stage 23 carrying the circuit board slides from the connecting plate 31 to the position of the collection tank 32. If subsequent processing is to be carried out, the placement stage 23 and the circuit board can be transferred together.
[0048] By setting up the fifth cylinder 25, the fixing plate 21, and the column 26 in cooperation, a foldable structure is achieved. The folding structure satisfies the condition that the placement platform 23 slides down from the fixing plate 21, and finally achieves the effect that the placement platform 23 and the circuit board slide down into the collection tank 32 together.
[0049] Specifically, the circuit board is first placed on the placement platform 23, then the two sets of fixing plates 21 are activated to fix the placement platform 23. Next, the second cylinder 102 is activated to move the screen printing plate 17 down to fit against the placement platform 23. Ink is then placed inside the screen printing plate 17. Then, the third cylinder 103 is activated to adjust the position of the scraper 16 so that the scraper 16 comes into contact with the ink. Finally, the first cylinder 101 is activated to move the scraper 16 back and forth to distribute the ink evenly. At the same time, the third cylinder 103 also applies a certain pressure to the scraper 16 during its back and forth movement, so that the ink passes through the mesh of the screen printing plate 17 under the pressure and is transferred to the surface of the circuit board located below the screen printing plate 17, thus realizing the printing of the circuit board. After the circuit board printing is completed, the fixing plates 21 are activated to loosen the fixation on the placement platform 23. The fifth cylinder 25 is activated, and the fifth cylinder 25 causes the fixing plates 21 to tilt. At this time, the placement platform 23 slides down along the connecting plate 31 from the fixing plates 21 to the collection tank 32, thus completing the collection of the circuit board.
[0050] Obviously, the embodiments described above are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of this utility model.
