Description
Technical Field
[0001] The utility model relates to the technical field of ceramic substrate manufacturing, and more specifically, to a screen printing device for ceramic substrates. Background Art
[0002] A ceramic substrate refers to a special process board in which a copper foil is directly bonded to the surface of an alumina or aluminum nitride ceramic substrate at high temperature. The manufactured ultra-thin composite substrate has excellent electrical insulation performance, high thermal conductivity, excellent soldering performance, and high adhesion strength, and can be etched into various patterns like a PCB board, with a large current-carrying capacity. Therefore, ceramic substrates have become the basic materials for high-power power electronic circuit structure technology and interconnection technology.
[0003] In the production and processing of ceramic substrates, screen printing processing operations need to be performed on the ceramic substrates. Specifically, an operator places the ceramic substrate under the outer frame equipped with a screen, then covers the screen on the ceramic substrate, and then gently brushes the screen with an oil brush, so that the ink penetrates from the screen onto the ceramic substrate, thereby achieving the purpose of screen printing on the ceramic substrate. However, since most of the screen and the outer frame are directly fixed together, after use, due to the inability to directly disassemble the screen and the outer frame, a set of outer frame and screen can only be used once, which will cause waste of resources. Summary of the Utility Model
[0004] The purpose of the utility model is to provide a screen printing device for ceramic substrates to solve the problems raised in the above background art:
[0005] In the production and processing of ceramic substrates, screen printing processing operations need to be performed on the ceramic substrates. Specifically, an operator places the ceramic substrate under the outer frame equipped with a screen, then covers the screen on the ceramic substrate, and then gently brushes the screen with an oil brush, so that the ink penetrates from the screen onto the ceramic substrate, thereby achieving the purpose of screen printing on the ceramic substrate. However, since most of the screen and the outer frame are directly fixed together, after use, due to the inability to directly disassemble the screen and the outer frame, a set of outer frame and screen can only be used once, which will cause waste of resources.
[0006] To achieve the above purpose, the utility model provides the following technical solutions:
[0007] A screen printing device for a ceramic substrate, comprising an outer frame and a screen. A first baffle is slidably connected to the upper surface of the outer frame. There are two first baffles in total, and the two first baffles are symmetrically distributed. One side of the outer frame is rotatably connected to a threaded rod, and a movable plate is threadedly connected to the outside of the threaded rod. One of the first baffles is fixedly connected to the movable plate. First grooves are formed at both ends of the first baffle. A connecting plate is slidably connected to the inside of the first groove. A second baffle is fixedly connected between adjacent two connecting plates. An inclined groove is formed inside the first baffle. The inclined grooves are distributed on the upper and lower surfaces of the first baffle, respectively above and below the connecting plate, and the inclined groove communicates with the first groove. A sliding rod is slidably connected to the inside of the inclined groove, and the sliding rod is fixedly connected to the connecting plate. The first baffle and the second baffle can be moved simultaneously through the inclined groove and the sliding rod.
[0008] Preferably, a sliding groove is formed on the upper surface of the outer frame. Sliders are fixedly connected to the bottoms of the first baffle and the second baffle. The outer side wall of the slider fits with the inner side wall of the sliding groove, and the slider is slidably connected to the sliding groove. Through the cooperation of the slider and the sliding groove, the first baffle and the second baffle will move more smoothly on the upper surface of the outer frame. At the same time, the cross-sections of the slider and the sliding groove are narrow at the top and wide at the bottom, which can prevent the first baffle and the second baffle from separating from the outer frame.
[0009] Preferably, a second groove is formed inside the outer frame. A rotating plate is rotatably connected to the inside of the second groove. The rotating plate is used in cooperation with the screen. When the first baffle and the second baffle move outward from the outer frame, they will squeeze the rotating plate, and then the rotating plate will push the screen out of the outer frame, which is beneficial to taking out the screen.
[0010] Preferably, the rotating plate is of an L-shaped structure. When the first baffle and the second baffle move outward from the outer frame, one end of the rotating plate will be squeezed. Since the rotating plate is of an L-shaped structure, the other end of the rotating plate will tilt upward.
[0011] Preferably, both the first baffle and the second baffle are of an isosceles trapezoid structure. The two ends of the first baffle and the second baffle of the isosceles trapezoid structure are inclined surfaces, which can ensure that the first baffle and the second baffle can be mutually joined.
[0012] Preferably, the first baffle and the second baffle have the same size. The two first baffles and the two second baffles can be joined to form a square frame, and this square frame is adapted to the outer frame, making the whole device more regular.
[0013] Compared with the prior art, the beneficial effects of the present utility model are:
[0014] 1) When the silk-screen printing device of this ceramic substrate is in use, if the silk screen needs to be replaced, the user can rotate the threaded rod on one side of the outer frame in the forward direction. At this time, both of the two first baffles and the two second baffles move to the outside of the outer frame simultaneously. The silk screen installed in the outer frame is no longer blocked by the first baffles and the second baffles. The user takes out the silk screen from the outer frame, then puts a new silk screen in, and finally the user rotates the threaded rod in the reverse direction. The first baffles and the second baffles are joined together in pairs to re-block and position the silk screen, achieving the purpose of reusing the outer frame and avoiding the situation of resource waste caused by direct discard.
[0015] 2) When the silk-screen printing device of this ceramic substrate is in use, when the user rotates the threaded rod in the forward direction, the first baffle and the second baffle will move to the outside of the outer frame and squeeze one end of the rotating plate. Since the rotating plate can rotate in the second groove on the outer frame, when one end of the rotating plate is squeezed by the first baffle and the second baffle, the other end of the rotating plate will rotate upward and lift out of the second groove, causing the rotating plate to push the silk screen in the outer frame upward. Finally, the silk screen also automatically pops out of the outer frame during the process of the separation and opening of the first baffle and the second baffle, thus facilitating the user's operation of taking the silk screen and further improving the replacement efficiency of the silk screen.

[0022] In the production and processing of ceramic substrates, screen printing operations need to be performed on the ceramic substrates. Specifically, the operator places the ceramic substrate under the outer frame equipped with a screen, then covers the screen on the ceramic substrate, and then gently brushes the screen with an oil brush, so that the ink penetrates from the screen onto the ceramic substrate, thus achieving the purpose of screen printing on the ceramic substrate. However, since the screen and the outer frame are mostly directly fixed together, after use, due to the inability to directly disassemble the screen and the outer frame, a set of outer frame and screen can only be used once, which will cause waste of resources. This problem is solved through the following solution.
[0023] Please refer to Figures 1 to 5 , a screen printing device for ceramic substrates, including an outer frame 1 and a screen 2. A first baffle 5 is slidably connected to the upper surface of the outer frame 1. There are two first baffles 5 in total, and the two first baffles 5 are symmetrically distributed. One side of the outer frame 1 is rotatably connected to a threaded rod 3. An activity plate 4 is threadedly connected to the outside of the threaded rod 3. One of the first baffles 5 is fixedly connected to the activity plate 4. When the user rotates the threaded rod 3, the threaded rod 3 will drive one of the first baffles 5 to move through the activity plate 4. First grooves 6 are opened at both ends of the first baffle 5. A connecting plate 7 is slidably connected to the inside of the first groove 6. A second baffle 8 is fixedly connected between adjacent two connecting plates 7. An inclined groove 9 is opened inside the first baffle 5. The inclined grooves 9 are distributed on the upper and lower surfaces of the first baffle 5, respectively above and below the connecting plate 7. The inclined groove 9 is communicated with the first groove 6. A sliding rod 10 is slidably connected to the inside of the inclined groove 9. The sliding rod 10 is fixedly connected to the connecting plate 7. Through the inclined groove 9 and the sliding rod 10, the first baffle 5 and the second baffle 8 can be moved simultaneously.
[0024] A chute 11 is opened on the upper surface of the outer frame 1. The bottoms of the first baffle 5 and the second baffle 8 are both fixedly connected with sliders 12. The outer side walls of the sliders 12 are attached to the inner side walls of the chute 11. The sliders 12 are slidably connected to the chute 11. Through the cooperation of the sliders 12 and the chute 11, the first baffle 5 and the second baffle 8 are limited, so that the first baffle 5 and the second baffle 8 will move more smoothly when moving on the upper surface of the outer frame 1. At the same time, the cross-sections of the sliders 12 and the chute 11 are narrow at the top and wide at the bottom, which can prevent the first baffle 5 and the second baffle 8 from separating from the outer frame 1.
[0025] Both the first baffle 5 and the second baffle 8 are of isosceles trapezoid structures. The two ends of the isosceles trapezoid-structured first baffle 5 and second baffle 8 are inclined surfaces, which can ensure that the first baffle 5 and the second baffle 8 can be mutually joined.
[0026] The first baffle 5 and the second baffle 8 have the same size. The two first baffles 5 and the two second baffles 8 can be joined to form a square frame, and this square frame is adapted to the outer frame 1, making the overall device more regular.
[0027] Usage steps of the present utility model: When the silk-screen printing device of this ceramic substrate is in use, if it is necessary to replace the silk screen 2, the user can rotate the threaded rod 3 on one side of the outer frame 1 in the positive direction. The threaded rod 3 will drive one of the first baffles 5 to move outward of the outer frame 1 through the movable plate 4. During this process, the inclined groove 9 on the first baffle 5 will squeeze the sliding rod 10 on the connecting plate 7. At this time, the sliding rod 10 will drive the connecting plate 7 to move away from the first baffle 5, so that the connecting plate 7 drives the two second baffles 8 located on both sides of the first baffle 5 to also move outward of the outer frame 1 at the same time. At the same time, the sliding rod 10 on the connecting plate 7 at the other end of the second baffle 8 will squeeze the inner wall of the inclined groove 9 on the other first baffle 5, so that the other first baffle 5 also moves outward of the outer frame 1 synchronously. Finally, the two first baffles 5 and the two second baffles 8 all move outward of the outer frame 1 at the same time. The silk screen 2 installed in the outer frame 1 is no longer blocked by the first baffle 5 and the second baffle 8. The user takes out the silk screen 2 from the outer frame 1, then puts the new silk screen 2 in, and finally the user rotates the threaded rod 3 in the reverse direction. The first baffle 5 and the second baffle 8 are joined together in pairs to re-block and position the silk screen 2, achieving the purpose of reusing the outer frame 1 and avoiding the situation of resource waste caused by direct discard. Embodiment
[0028] Since the silk screen 2 is directly placed in the outer frame 1 and limited and fixed, and the outer frame 1 has a certain depth. When the user takes the silk screen 2, due to the relatively small gap between the silk screen 2 and the outer frame 1 and the user's fingers cannot reach in, the work of taking the silk screen 2 will be relatively inconvenient. The following solution is used to solve this problem.
[0029] Please refer to Figures 1 to 5 , the difference in the basis of combination with the embodiment is that a second groove 13 is opened inside the outer frame 1, and a rotating plate 14 is rotatably connected inside the second groove 13. The rotating plate 14 is used in cooperation with the silk screen 2. When the first baffle 5 and the second baffle 8 move outward of the outer frame 1, they will squeeze the rotating plate 14, and then push the silk screen 2 out of the outer frame 1 through the rotating plate 14, which is convenient for the user to take out the silk screen 2 from the outer frame 1.
[0030] The rotating plate 14 is of an L-shaped structure. When the first baffle 5 and the second baffle 8 move outward of the outer frame 1, one end of the rotating plate 14 will be squeezed. Since the rotating plate 14 is of an L-shaped structure, the other end of the rotating plate 14 will tilt upward, thereby pushing the silk screen 2 already installed in the outer frame 1 upward.
[0031] Usage steps of the present utility model: When the silk-screen printing device of this ceramic substrate is in use, when the user rotates the threaded rod 3 clockwise to drive the first baffle 5 and the second baffle 8 to move outward from the outer frame 1, the first baffle 5 and the second baffle 8 will squeeze one end of the rotating plate 14. Since the rotating plate 14 can rotate in the second groove 13 on the outer frame 1, when one end of the rotating plate 14 is squeezed by the first baffle 5 and the second baffle 8, the other end of the rotating plate 14 will rotate upward and lift out of the second groove 13, so that the rotating plate 14 pushes the silk screen 2 in the outer frame 1 to move upward. Finally, the silk screen 2 also automatically pops out of the outer frame 1 during the process of the separation and opening of the first baffle 5 and the second baffle 8, which facilitates the user's operation of taking the silk screen 2 and can further improve the replacement efficiency of the silk screen 2.
[0032] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art should understand that the present utility model is not limited by the above embodiments. The above embodiments and the descriptions in the specification are only the preferred examples of the present utility model and are not used to limit the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and these changes and improvements all fall within the scope of the present utility model claimed.
