It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the present application. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the present application.

[0048] Example 1: A CTP plate automatic glue coating device, as Figures 1-6 and Figure 9As shown, it comprises: a shell 1, a plurality of guide rollers 2 are rotatably connected in the shell 1, the guide rollers 2 are used to guide the movement of the plate material, a gluing module 3 is arranged in the shell 1; a support frame 4 is fixedly connected in the shell 1, the support frame 4 is fixedly connected with an electric push rod 5, the extension end of the electric push rod 5 is fixedly connected with a scraper 6, the scraper 6 is used to level the glue on the surface of the plate material; symmetrically distributed guide frames 7 are fixedly connected in the shell 1, the opposite sides of the symmetrically distributed guide frames 7 are provided with guide grooves 8, the connecting rods 9 are slidably connected in the guide grooves 8; symmetrically distributed push plates 10 are arranged between the symmetrically distributed connecting rods 9, the included angle of the glue side of the symmetrically distributed push plates 10 is less than 180°, and the lower part of the push plate 10 is higher than the lower part of the scraper 6, the push plate 10 is used to pre-level the glue on the surface of the plate material; symmetrically distributed power assemblies are arranged on different guide frames 7, and are used to drive the connecting rods 9 to move.

[0049] The above scheme provides a method for pre-removing the glue on the surface of the plate material during the gluing process of the plate material, and reduces the problem of uneven distribution of the glue on the surface of the plate material; the shell 1 is provided with an inlet and an outlet, and dust removal modules are arranged on the upper sides of the inlet and the outlet of the shell 1, which are used to clean the impurities on the upper surface of the plate material, a traction module is arranged outside the shell 1, which is used to pull the plate material to move horizontally, the guide rollers 2 are five, which are used to support the plate material and reduce the probability of deformation of the plate material during the gluing process, the gluing module 3 is an existing gluing device, and its specific structure and use mode will not be described in detail, the gluing module 3 glues the upper side of the plate material, and in this text, the gluing amount of the gluing module 3 on the plate material gradually decreases from the edge to the middle, and the specific gluing amount of the gluing module 3 can be adjusted according to the actual situation; the support frame 4 is located at the right part of the shell 1, and the support frame 4 has two electric push rods 5 which are distributed in front and back, which are used to increase the fixing effect of the scraper 6, and the two electric push rods 5 are used to drive the scraper 6 to move up and down, so as to control the thickness of the glue on the plate material by adjusting the gap between the scraper 6 and the upper side of the plate material; the guide frames 7 are two and are distributed in front and back in the shell 1, in this embodiment, the guide grooves 8 are ordinary transverse grooves, the depths of which are the same, and are only used to guide the horizontal movement of the connecting rods 9, the connecting rods 9 are L-shaped rods, the horizontal parts of which slide in the guide grooves 8, in this embodiment, the vertical parts of the connecting rods 9 are fixedly connected with the adjacent push plates 10, and there is an included angle between the two push plates 10, the distance between the two push plates 10 gradually decreases from left to right, which is used to make the glue on the front and back sides of the plate material higher than the lower side of the push plate 10 when the plate material passes through the push plate 10, so that the glue flows along the left side of the push plate 10 to the middle part of the plate material, thereby making the glue spread in a specified direction, reducing the situation that the glue cannot be supplemented in time due to uneven distribution of the glue, the push plate 10 is located on the left side of the scraper 6, and the lower side of the push plate 10 is higher than the lower side of the scraper 6, and is only used to pretreat the glue on the plate material.

[0050] Further, as shown in Figures 4-7 and Figure 9 The power assembly comprises a motor 11 fixed to the guide frame 7, an output shaft of the motor 11 is fixed with a threaded rod 12, the threaded rod 12 is rotatably connected with the guide frame 7; a sliding frame 13 is threadedly connected with the threaded rod 12, the sliding frame 13 is slidably connected with the guide frame 7; a transmission frame 14 is arranged on the connecting rod 9, and the transmission frame 14 is slidably connected with the sliding frame 13.

[0051] Further, as shown in Figures 3-5 The back side of each of the symmetrically distributed pushing plates 10 is fixed with a blocking plate 15, and the distance between the symmetrically distributed blocking plates 15 increases with the increase of the distance between the symmetrically distributed pushing plates 10.

[0052] The above scheme provides a way to quickly consume the accumulated glue on the left side of the pushing plate 10 after the glue accumulates on the left side of the pushing plate 10; a visual detection module is arranged in the shell 1 for observing the accumulation of glue on the left side of the pushing plate 10 (the accumulation of glue can be set according to actual conditions), the visual detection module on the shell 1 is electrically connected with the motor 11, when the accumulation of glue on the left side of the pushing plate 10 reaches a specified value, the visual detection module on the shell 1 transmits a signal to the motor 11, and the motor 11 is started, the motor 11 is located at the right part of the guide frame 7, the motor 11 is a bidirectional motor, and the output shaft of the motor 11 can drive the threaded rod 12 to rotate in different directions; the lower part of the sliding frame 13 is threadedly connected with the threaded rod 12, the rear side of the sliding frame 13 is in contact with the guide frame 7, and the guide frame 7 is used to limit the position of the sliding frame 13 to prevent the sliding frame 13 from rotating with the threaded rod 12; in this embodiment, the transmission frame 14 is fixed with the adjacent connecting rod 9; the minimum distance between the opposite sides of the two blocking plates 15 is the same as the width of the plate material, which is used to prevent the glue from overflowing along the edge of the plate material during the movement of the pushing plate 10 to the left.

[0053] Work flow: when the device is used to glue the plate, the worker passes the plate through the shell 1 and makes it adhere to the guide roller 2, after the plate is placed, the worker starts the electric push rod 5, adjusts the position of the scraper 6 according to the thickness of the glue required by the plate, after the adjustment is completed, the worker closes the electric push rod 5 and starts the glue coating module 3 to coat glue on the upper side of the plate, then the worker starts the external traction device to pull the plate to move to the right, the plate moves to the right along the guide roller 2, the glue coating module 3 coats glue on the upper side of the plate and makes the thickness of the glue on the front and back parts of the plate greater than the thickness of the glue in the middle part.

[0054] As the printing plate moves to the right, when the adhesive on the plate comes into contact with the pusher plate 10, the pusher plate 10 initially smooths out the adhesive on the plate. During this process, since the thickness of the adhesive on the front and back sides of the plate is greater than the thickness of the adhesive in the middle of the plate, the excess adhesive on the plate will move along the left side of the pusher plate 10 towards the middle, and fill the missing adhesive height during the movement, ensuring that the thickness of the adhesive on the plate is similar in all places after the plate passes through the pusher plate 10, so that the scraper 6 can then smooth out the adhesive, thereby improving the accuracy of the adhesive coating on the plate. After the initial treatment by the pusher plate 10, the plate moves to the scraper 6 for final smoothing treatment.

[0055] During the process of the pusher plate 10 smoothing the glue, when a certain amount of glue accumulates on the left side of the pusher plate 10 (this value can be set according to the actual situation), the operator starts the motor 11. The output shaft of the motor 11 drives the threaded rod 12 to rotate, and the threaded rod 12 drives the sliding frame 13 to move to the left. The sliding frame 13 drives the connecting rod 9 to move synchronously through the transmission frame 14. The connecting rod 9 drives the pusher plate 10 to move to the left, so that the pusher plate 10 pushes the accumulated glue to the left to fill the glue gap area. At the same time, the baffle plate 15 moves with the pusher plate 10. The adhesive is moved together to prevent the accumulated glue from overflowing along the edge of the plate. During this process, the output of the adhesive application module 3 is reduced, which reduces the thickness of the glue on the plate surface, thereby quickly consuming the accumulated glue on the left side of the pusher plate 10. When the accumulated glue on the left side of the pusher plate 10 is consumed, the output shaft of the motor 11 rotates in the reverse direction, causing the sliding frame 13 to move its parts in the reverse direction to reset. The output of the adhesive application module 3 is restored until the plate processing is completed. Then, the operator turns off the electrical components and repeats the above process to process other plates.

[0056] Example 2: Based on Example 1, such as Figure 4 , Figure 5 and Figure 9 As shown, it also includes: an adjustment component, disposed on the symmetrically distributed pusher plates 10, the adjustment component being used to adjust the angle between the symmetrically distributed pusher plates 10, the adjustment component including: a rotating rod 16, rotatably connected to the symmetrically distributed pusher plates 10, the symmetrically distributed pusher plates 10 being rotatably connected to each other, a torsion spring 17 fixedly connected between the symmetrically distributed pusher plates 10, a connecting rod 9 being slidably connected to the transmission frame 14, and a connecting rod 9 being rotatably connected to the pusher plates 10; a limiting component, disposed on the rotating rod 16, for limiting the position of the rotating rod 16; and a scraping component, disposed on the symmetrically distributed pusher plates 10, for cleaning up the material accumulated near the scraper 6.

[0057] Furthermore, such as Figure 8As shown, the guide groove 8 consists of a first slide groove 801, a second slide groove 802 and two inclined grooves 803. The first slide groove 801 is parallel to the second slide groove 802. The first slide groove 801 is located at the lower part of the guide groove 8. Both inclined grooves 803 are used to connect the second slide groove 802 and the first slide groove 801.

[0058] Furthermore, such as Figure 8 As shown, the depth of the first groove 801 is less than the depth of the second groove 802.

[0059] The above solution provides a way to adjust the angle between the two pusher plates 10 so that the pusher plates 10 are parallel to the scraper 6; in this embodiment, the pusher plates 10 are rotatably connected to the connecting rod 9, the connecting rod 9 is slidably connected to the transmission frame 14, the adjacent sides of the two pusher plates 10 are rotatably connected, the rotating rod 16 is used to connect the two pusher plates 10, and the angle of the pusher plates 10 is adjusted by pulling the adjacent edges of the pusher plates 10. The torsion spring 17 is always in a stored state, so that the pusher plates 10 push the glue more stably. The torsion spring 17 is used to drive the pusher plates 10 to rotate clockwise ( Figure 5 (The pusher plate 10, viewed from top to bottom); the depth of the first groove 801 is less than the depth of the second groove 802. The two second grooves 802 are used to increase the distance between the two connecting rods 9, so that the torsion spring 17 can drive the pusher plate 10 to rotate. The first groove 801 is a horizontal groove, and the length of the first groove 801 is less than the length of the guide groove 8 projected on the horizontal plane. The second groove 802 consists of two horizontal grooves of different lengths and a vertical groove. The two horizontal grooves on the second groove 802 are connected by the vertical groove above them, and the longer horizontal groove of the second groove 802 is located above the shorter horizontal groove above it. The left part of the lower horizontal groove of the second groove 802 is connected to the right part of the first groove 801 by an inclined groove 803. The left part of the upper horizontal groove of the second groove 802 is connected to the left part of the first groove 801 by an inclined groove 803. Another inclined groove 803 is connected between them. The inclined groove 803 is used to bridge the height difference between the first slide groove 801 and the second slide groove 802. Initially, the connecting rod 9 is located in the horizontal groove at the bottom of the second slide groove 802. When the connecting rod 9 is located in the second slide groove 802, the angle between the two push plates 10 is greater than the angle between the two push plates 10 when the connecting rod 9 is located in the first slide groove 801. This is used to accelerate the movement of glue towards the middle of the board when the push plate 10 moves to the left and consumes glue, thereby reducing the probability of glue overflowing from the edge of the board. The sliding frame 13 is provided with a vertical slide groove. The height of the slide groove is not less than the height of the guide groove 8. This is used to enable the transmission frame 14 to drive the parts on it to move up and down along the sliding frame 13 when the connecting rod 9 moves up and down along the guide groove 8.

[0060] Furthermore, such as Figures 4-7 , Figure 9 and Figure 10As shown, the limiting assembly comprises: a limiting rod 18 fixed to the rotating rod 16, and symmetrically distributed transmission frames 14 in sliding connection with the limiting rod 18; symmetrically distributed limiting frames 19 respectively fixed to different connecting rods 9; and symmetrically distributed limiting rings 20 all fixed to the limiting rod 18, and the limiting frames 19 are used to push the limiting rings 20 to move.

[0061] Further, as shown in Figure 4 、 Figure 5 and Figure 9 , the scraping assembly comprises: symmetrically distributed scrapers 21 respectively in sliding connection with different pushing plates 10, and the scrapers 21 are used to scrape the accumulated material on the scraper 6, and the scrapers 21 are fixed with springs 22 between adjacent pushing plates 10.

[0062] In the above scheme, the rotating rod 16 is an L-shaped rod, the horizontal part of the rotating rod 16 is located at the upper end and faces the right side, the limiting rod 18 is located at the right part of the horizontal part of the rotating rod 16, and in the process of moving the connecting rod 9 along the lower inclined groove 803 to the left, the limiting rod 18 moves rightward relative to the pushing plate 10 along the transmission frame 14, so that the rotating rod 16 drives the connecting part of the two pushing plates 10 to move rightward; the distance between the right parts of the two limiting frames 19 gradually increases from left to right, and when the connecting rod 9 drives the limiting frame 19 to move rightward (as shown in Figure 6 from front to back), the limiting frame 19 drives the limiting rod 18 to move rightward relative to the transmission frame 14 by extruding the limiting ring 20; the lower side of the limiting ring 20 is provided with a round rod adapted to the shape change of the limiting frame 19; the scraper 21 is made of rubber material, which is used to reduce the hard friction between the scraper 21 and the scraper 6, avoid the damage of the scraper 6 and affect the scraping of the glue, and the elastic deformation of the scraper 21 itself can adapt to the shape change of the scraper 6, improve the cleaning effect, the left part of the scraper 21 is provided with a round rod, which is inclined upward from left to right, which is used to make the scraper 21 move leftward and downward after being extruded, and finally make the lower side of the scraper 21 move to the lower side of the pushing plate 10, increase the cleaning area of the scraper 6, and initially, the lower side of the scraper 21 is higher than the lower side of the pushing plate 10.

[0063] Workflow: After a certain amount of glue is gathered on the left side of the pushing plate 10, the worker starts the motor 11, the output shaft of the motor 11 drives the threaded rod 12 to rotate, the threaded rod 12 drives the sliding frame 13 to move left, the sliding frame 13 drives the transmission frame 14 to move left, the transmission frame 14 drives the connecting rod 9 and the limiting rod 18 to move left, the connecting rod 9 moves left along the horizontal groove at the lower part of the second sliding groove 802, and at the same time the connecting rod 9 drives the pushing plate 10 to move left repeatedly, when the connecting rod 9 is separated from the second sliding groove 802 and enters the inclined groove 803, taking the moving direction of the rear connecting rod 9 and the parts above it as an example, the inclined groove 803 pushes the connecting rod 9 to move forward, the connecting rod 9 drives the rear part of the pushing plate 10 and the limiting frame 19 to move forward, the limiting frame 19 moves to the right to press the limiting ring 20, the limiting ring 20 drives the limiting rod 18 to move right relative to the connecting rod 9, the limiting rod 18 drives the rotating rod 16 to move, the rotating rod 16 cooperates with the forward thrust of the connecting rod 9 to drive the adjacent side of the pushing plate 10 to move right, thereby making the two pushing plates 10 rotate and making the torsional spring 17 store energy, the rotation of the two pushing plates 10 makes the included angle between them decrease, speeding up the speed of the glue moving to the middle, reducing the probability of glue overflowing from the edge of the plate during the process of pushing the glue left to move, at the same time the pushing plate 10 drives the blocking plate 15 to swing synchronously, making the blocking plate 15 gradually approach the edge of the plate, further reducing the probability of glue overflowing from the edge of the plate, until the connecting rod 9 is separated from the inclined groove 803 and enters the first sliding groove 801, the connecting rod 9 stops moving, the limiting rod 18 stops moving, and the pushing plate 10 stops rotating, at this time the front side of the blocking plate 15 and the rear edge of the plate are in the same vertical plane.

[0064] After the pusher plate 10 stops rotating, it repeats the above process, moving to the left to quickly consume the accumulated glue, until the connecting rod 9 moves to the connection point between the left side of the first slide groove 801 and the left inclined groove 803. Then, the motor 11 shuts off, and the torsion spring 17 drives the pusher plate 10 to rotate in the opposite direction, causing the pusher plate 10 to push the connecting rod 9 backward. Simultaneously, the connecting rod 9 drives the parts on it to move upward along the left inclined groove 803, causing the pusher plate 10 to move the parts on it upward away from the plate material, until the connecting rod 9 moves to the connection point between the left inclined groove 803 and the second slide groove 802. Then, the pusher plate 10 stops rotating, the motor 11 starts, and drives the threaded rod 12 to rotate in the opposite direction, causing the sliding frame 13 to move the parts on it in the opposite direction, until the connecting rod 9 moves to the connection point between the first slide groove 801 and the second slide groove 802. After the second chute 802 is on the right, the motor 11 is turned off. At this time, the scraper 21 is located above the scraper 6. Under the action of gravity, the connecting rod 9 drives the parts on it to move downward. When the scraper 21 contacts the scraper 6, the scraper 21 cleans the glue accumulated near the scraper 6. During this process, the scraper 21 is squeezed by the scraper 6 and moves to the left relative to the pusher plate 10 and compresses the spring 22. When the connecting rod 9 moves to the lower part of the second chute 802, the connecting rod 9 and the parts on it stop moving. The operator starts the motor 11, so that the pusher plate 10 drives the parts on it to move to the left to reset. During this process, the spring 22 pushes the scraper 21 to reset until the scraper 21 separates from the scraper 6. Then the motor 11 is turned off, and the pusher plate 10 repeats the above process to level the glue.

[0065] Example 3: Based on Example 2, such as Figure 6 and Figure 10 As shown, it also includes: symmetrically distributed transmission components, which are respectively set on different guide frames 7. The transmission components are used to provide power for the movement of the transmission frame 14. The transmission components include: an extrusion frame 23, which is slidably connected to the guide frame 7. A tension spring 24 is fixed between the extrusion frame 23 and the guide frame 7; and an extrusion block 25, which is fixed to the side of the transmission frame 14 near the extrusion frame 23. The extrusion frame 23 is used to push the extrusion block 25 to move.

[0066] Furthermore, such as Figure 8 and Figure 9 As shown, the guide frame 7 is provided with multiple rubber blocks 26, which are located in the second slide groove 802. The rubber blocks 26 are used to increase the resistance to the movement of the connecting rod 9.
