Description

Technical Field

[0001] This invention relates to the field of solder mask fabrication technology for printed circuit boards, and in particular to a method for improving the exposed copper at the connection points of semi-rigid-flex boards. Background Technology

[0002] Currently, most circuit board manufacturers use a two-stage solder mask process when producing semi-rigid-flex products. This involves first applying solder mask to the bent areas and then applying it to the non-bent areas. This process has complex parameters, involves many steps, and is prone to causing copper exposure at the connection between the bent and non-bent areas.

[0003] In response to the above situation, those skilled in the art have realized that by optimizing the engineering data design of the rigid-flex connection area, the ink in both the bending and non-bending areas can be completed in one go, thereby reducing the solder resist manufacturing process and improving the problem of exposed copper in both the bending and non-bending areas.

[0004] In actual implementation, the boundary between the bending area and the rigid plate area is used as the line. First, the flexible plate ink is printed and exposed, and the exposed pattern is ensured to extend more than 0.4mm outside the bending area. Then, the rigid plate ink is sprayed, with the rigid plate ink 0.1mm inward from the rigid plate boundary, and the overlap between the rigid plate ink and the flexible plate ink is greater than 0.3mm.

[0005] However, after practical application by those skilled in the art, the above manufacturing method still has some drawbacks. The most obvious one is that since the bending area divides the rigid plate area into left and right parts, when spraying the rigid plate ink on the rigid plate area, it is necessary to repeat the spraying operation twice to complete the spraying work on both sides of the rigid plate area of ​​the bending area. This increases the production steps and reduces the solder resist manufacturing efficiency of the semi-rigid flexible plate.

[0006] In order to ensure the coverage of the ink on the rigid board, interference spraying is often required when spraying the edge of the rigid board area. As a result, some ink will fall from the edge of the rigid board area into the working environment, which will not only pollute the working environment, but also waste ink.

[0007] Therefore, it is necessary to invent a manufacturing method to improve the exposed copper at the connection point of the semi-rigid flexible plate in order to solve the above problems. Summary of the Invention

[0008] The purpose of this invention is to provide a method for improving the manufacturing of exposed copper at the connection point of a semi-rigid-flexible plate, so as to solve the problems mentioned in the background art.

[0009] To achieve the above objectives, the present invention provides the following technical solution: a method for improving the exposed copper at the connection position of a semi-rigid-flexible plate, wherein the method is implemented by a device for improving the exposed copper at the connection position of a semi-rigid-flexible plate, the device comprising a housing, side plates fixedly disposed on the top of both sides of the housing, a conveyor belt for conveying the semi-rigid-flexible plate disposed on the inner side of the housing, a lifting mechanism fixedly disposed on the inner side of the housing, triggering mechanisms disposed on both sides of the lifting mechanism, a positioning and blocking mechanism fixedly disposed between the two side plates, an ink recovery mechanism disposed on the top of the inner side of the positioning and blocking mechanism, a spraying drive mechanism disposed above the positioning and blocking mechanism, the spraying drive mechanism being connected to the lifting mechanism, and trigger-type ink spraying mechanisms disposed on both sides of the top of the spraying drive mechanism;

The longitudinal groove is opened on the outer wall of the shield. The inner slider is slidably installed inside the longitudinal groove. The positioning plate is slidably installed inside the shield and fixedly connected to the inner slider. The outer slider is slidably installed outside the shield and fixedly connected to the inner slider. The two shields are respectively fixedly installed on the top of the two positioning plates located on the left and right sides. The two guide grooves are respectively opened on the top of the two shields.

[0016] Preferably, the ink recovery mechanism includes four ink recovery components, multiple recovery branch pipes and a recovery main pipe, and each of the ink recovery components includes a guide rail, an electric slider and a scraper.

[0017] Preferably, the four ink recovery components are rectangularly fixedly arranged on the top of the inner side of the shield, both ends of the guide rail are fixedly connected to the inner wall of the shield, the electric slider is slidably arranged on the outside of the guide rail, the scraper is fixedly arranged at the bottom of the electric slider, and multiple recovery branch pipes are evenly fixedly arranged through the outside of the shield, and the main recovery pipe is connected to multiple recovery branch pipes.

[0018] Preferably, the spraying drive mechanism includes a second guide rod, an L-shaped mounting plate, a drive block, a second screw, and a bevel gear.

[0019] Preferably, there are two second guide rods, which are respectively located on both sides of the first screw and are fixedly connected to the inner wall of the housing. The L-shaped mounting plate is fixedly sleeved on the outside of the two second guide rods. The driving block is slidably sleeved on the outside of the two second guide rods and located on the front side of the L-shaped mounting plate. The second screw passes through the driving block and is threadedly connected to the driving block. There are two bevel gears, one of which is fixedly sleeved on the rear end of the second screw and the other is fixedly sleeved on the top of the first screw. The two bevel gears mesh with each other.

[0020] Preferably, the trigger-type ink spraying mechanism includes a spraying plate and two sets of trigger-type ink spraying components. Each set of trigger-type ink spraying components includes a rigid tube, a first flexible tube, a connecting block, a second flexible tube, a T-shaped plate, a through hole, and two second springs.

[0021] Preferably, the spray plate is located at the top of the inner side of the shielding cover, the rigid tube is fixedly installed through the top of the spray plate, the rigid tube passes through the L-shaped mounting plate and is fixedly connected to the L-shaped mounting plate, the first flexible tube is fixedly connected to the top of the rigid tube, the connecting block is fixedly sleeved at the outer end of the first flexible tube and is fixedly connected to the inner wall of the side plate, the second flexible tube is fixedly installed through the connecting block on the side away from the first flexible tube, the T-shaped plate is slidably installed through the top of the connecting block, the through hole is installed through the T-shaped plate, and the two second springs are respectively fixedly connected to the top two sides of the connecting block and are both fixedly connected to the T-shaped plate.

[0022] Preferably, the method specifically includes the following steps:

[0023] S1. Print and expose flexible plate ink, then transport the semi-rigid flexible plate to the top of the lifting mechanism via a conveyor belt. Then, the drive motor drives the first screw to rotate. When the first screw rotates, it drives the drive plate to rise continuously. The drive plate then drives the lifting plate to rise continuously. When the drive plate rises a distance of up to the first threshold, the lifting plate contacts the semi-rigid flexible plate. Subsequently, as the lifting plate continues to rise, the semi-rigid flexible plate on the conveyor belt is lifted upward by the lifting plate.

[0024] S2. When the rising distance of the drive plate reaches the second threshold, the lifting plate contacts the four positioning plates. At this time, the semi-rigid flexible plate moves between the four positioning plates. When the lifting plate continues to rise, the lifting plate pushes the four positioning plates, and the positioning plates slide upward along the inclined inner wall of the shield.

[0025] S3. When the drive plate rises to the third threshold, the inner slider moves to the top of the inner side of the longitudinal slide groove. At this time, the semi-rigid flexible plate arrives at the spraying station. At the same time, the four positioning plates contact each other from the front and back, and the semi-rigid flexible plate is positioned from the four sides. Meanwhile, the ends of the two shielding plates contact each other, forming a shielding area on the top of the semi-rigid flexible plate.

[0026] S4. Since the lifting plate can no longer rise, as the first screw continues to rotate, the drive plate cooperates with the lifting plate to shorten the telescopic rod. At this time, the first spring is compressed, and the outer shaft of the telescopic rod drives the trigger rod to continue to rise through the connecting plate.

[0027] S5. When the drive plate rises to the fourth threshold, the trigger rod pushes the T-shaped plate, the T-shaped plate moves up and stretches the second spring. When the drive plate rises to the fifth threshold, the through hole gradually moves between the second hose and the first hose. The ink inside the second hose passes through the through hole and enters the first hose. Then it enters the spray plate through the hard tube and is finally sprayed out through multiple spray holes at the bottom of the spray plate.

[0028] S6. During the rotation of the first screw, the second screw is continuously driven to rotate through the bevel gear. When the second screw rotates, it drives the drive block to reciprocate back and forth. When the drive block moves, it drives the spray plate to reciprocate back and forth through the rigid tube, thereby enabling the spray plate to perform interference spraying on the top of the semi-rigid flexible plate.

[0029] S7. During the interference spraying process, some ink falls on the top of the four positioning plates and the top of the two shielding plates. The ink on the top of the shielding plates flows to the top of the positioning plates under the guidance of the guide channel. The ink on the top of the positioning plates moves towards the recovery branch pipe under the push of the scraper driven by the electric slider, and is finally sucked out by the recovery main pipe through the recovery branch pipe.

[0030] S8. After the spraying is completed, the drive motor drives the first screw to rotate in the opposite direction, so that the sprayed semi-rigid flexible plate falls onto the conveyor belt and is output. At the same time, the next semi-rigid flexible plate to be sprayed is also conveyed to the top of the lifting mechanism while the current semi-rigid flexible plate is output.

[0031] The technical effects and advantages of this invention are as follows:

[0032] This invention incorporates a lifting mechanism, a triggering mechanism, a positioning and blocking mechanism, an ink recovery mechanism, a spraying drive mechanism, and a trigger-type ink spraying mechanism. The lifting mechanism lifts the semi-rigid flexible plate being printed and exposed with flexible circuit board ink, allowing it to enter the positioning and blocking mechanism. Simultaneously, the lifting mechanism triggers the positioning and blocking mechanism during the lifting process, enabling the positioning and blocking mechanism to position the semi-rigid flexible plate. Furthermore, once the semi-rigid flexible plate reaches the spraying station, the lifting mechanism, through the triggering mechanism, activates the trigger-type ink spraying mechanism. The system triggers the ink spraying mechanism, which, driven by the lifting mechanism, completes the interference spraying operation. Excess ink during the interference spraying process is collected by the ink recovery mechanism inside the positioning and masking mechanism. Compared with similar devices or methods in the prior art, this invention can complete the spraying of the hard plate area on the semi-rigid-flexible plate in a single spraying operation, improving the solder resist manufacturing efficiency of the semi-rigid-flexible plate, ensuring the spraying quality of the hard plate area, and recovering excess ink to avoid waste while avoiding unsuitable working environments.

[0039] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0040] This invention provides, for example Figure 1-5 The invention illustrates a method for improving the exposed copper at the connection points of a semi-rigid-flexible plate. This method is implemented using a fabrication device for improving the exposed copper at the connection points of a semi-rigid-flexible plate. The device includes a housing 1, with side plates 2 fixedly mounted on the top of both sides of the housing 1. A conveyor belt for transporting the semi-rigid-flexible plate is mounted inside the housing 1. A lifting mechanism 3 is also fixedly mounted inside the housing 1. Triggering mechanisms 4 are mounted on both sides of the lifting mechanism 3. A positioning and blocking mechanism 5 is fixedly mounted between the two side plates 2. An ink recovery mechanism 6 is mounted on the top of the inner side of the positioning and blocking mechanism 5. A spraying drive mechanism 7 is mounted above the positioning and blocking mechanism 5 and is connected to the lifting mechanism 3. Trigger-type ink spraying mechanisms 8 are mounted on both sides of the top of the spraying drive mechanism 7.

[0041] like Figure 2As shown, the lifting mechanism 3 includes a first screw 31, a drive plate 32, a first guide rod 33, a telescopic rod 34, a lifting plate 35, and a first spring 36. The first screw 31 passes through the outer shell 1 and is rotatably connected to the outer shell 1 via a bearing. A drive motor is fixedly installed on the top of the outer shell 1, and the first screw 31 is drively connected to the drive motor. The drive plate 32 is sleeved on the outside of the first screw 31 and threadedly connected to the first screw 31. There are two of each of the first guide rod 33, telescopic rod 34, and first spring 36. The two first guide rods 33 are slidably installed through the top two sides of the drive plate 32 and are fixedly connected to the outer shell 1. The two telescopic rods 34 are fixedly installed on the top two sides of the drive plate 32. The lifting plate 35 is fixedly connected to the top of the two telescopic rods 34. The two first springs 36 are sleeved on the outer side of the inner shaft of the two telescopic rods 34.

[0042] By setting the above structure, the drive motor drives the first screw 31 to rotate. When the first screw 31 rotates, it drives the drive plate 32 to rise continuously. The drive plate 32 then drives the lifting plate 35 to rise continuously. When the drive plate 32 rises a distance to the first threshold, the lifting plate 35 contacts the semi-rigid flexible plate. Subsequently, as the lifting plate 35 continues to rise, the semi-rigid flexible plate on the conveyor belt is lifted upward by the lifting plate 35.

[0043] like Figure 2 As shown, the triggering mechanism 4 includes a connecting plate 41 and a trigger rod 42. The connecting plate 41 is fixedly sleeved on the outside of the telescopic rod 34 and slidably sleeved on the outside of the first guide rod 33. The trigger rod 42 is fixedly sleeved on the top outside of the connecting plate 41.

[0044] By setting up the above structure, when the lifting plate 35 can no longer rise, as the first screw 31 continues to rotate, the drive plate 32 cooperates with the lifting plate 35, causing the telescopic rod 34 to shorten. At this time, the first spring 36 is compressed, and at the same time, the outer shaft of the telescopic rod 34 drives the trigger rod 42 to rise continuously through the connecting plate 41. As the trigger rod 42 rises continuously, it eventually triggers the trigger-type ink spraying mechanism 8.

[0045] like Figure 3 and Figure 4As shown, the positioning and blocking mechanism 5 includes a blocking cover 51, four positioning components, two blocking plates 56, and two guide channels 57. Each positioning component includes a longitudinal slide groove 52, an inner slider 53, a positioning plate 54, and an outer slider 55. The blocking cover 51 is fixedly disposed between two side plates 2. The four positioning components are rectangularly and slidably distributed inside the blocking cover 51. The longitudinal slide groove 52 is opened on the outer wall of the blocking cover 51. The inner slider 53 is slidably disposed inside the longitudinal slide groove 52. The positioning plate 54 is slidably disposed inside the blocking cover 51 and fixedly connected to the inner slider 53. The outer slider 55 is slidably disposed outside the blocking cover 51 and fixedly connected to the inner slider 53. The two blocking plates 56 are respectively fixedly disposed on the top of the two positioning plates 54 located on the left and right sides. The two guide channels 57 are respectively opened on the top of the two blocking plates 56.

[0046] By setting up the above structure, when the lifting plate 35 rises, the lifting plate 35 pushes the four positioning plates 54, and the positioning plates 54 slide upward along the inclined inner wall of the shield 51. When the inner slider 53 moves to the top of the inner side of the longitudinal slide groove 52, the semi-rigid flexible plate arrives at the spraying station. At the same time, the four positioning plates 54 contact each other end to end, and the semi-rigid flexible plate is positioned from all sides. Meanwhile, the ends of the two shield plates 56 contact each other, forming a shielding area on the top of the semi-rigid flexible plate.

[0047] like Figure 3 and Figure 4 As shown, the ink recovery mechanism 6 includes four ink recovery components, multiple recovery branch pipes 64, and a recovery main pipe 65. Each ink recovery component includes a guide rail 61, an electric slider 62, and a scraper 63. The four ink recovery components are rectangularly and fixedly arranged on the top of the inner side of the shield 51. Both ends of the guide rail 61 are fixedly connected to the inner wall of the shield 51. The electric slider 62 is slidably arranged on the outside of the guide rail 61. The scraper 63 is fixedly arranged at the bottom of the electric slider 62. The multiple recovery branch pipes 64 are evenly and fixedly arranged through the outside of the shield 51. The recovery main pipe 65 is connected to the multiple recovery branch pipes 64.

[0048] By setting up the above structure, during the interference spraying process, some ink falls on the top of the four positioning plates 54 and the top of the two baffle plates 56. The ink falling on the top of the baffle plates 56 flows to the top of the positioning plates 54 under the guidance of the guide groove 57. The ink on the top of the positioning plates 54 moves towards the recovery branch pipe 64 under the push of the scraper 63 driven by the electric slider 62, and is finally sucked out by the recovery main pipe 65 through the recovery branch pipe 64.

[0049] It should also be noted that the two ink recovery components located on the left side each include two electric sliders 62 and two scrapers 63, so as to clean the ink on the top of the adjacent positioning plate 54 while avoiding obstruction caused by the presence of the baffle plate 56.

[0050] like Figure 5 As shown, the spraying drive mechanism 7 includes a second guide rod 71, an L-shaped mounting plate 72, a drive block 73, a second screw 74, and a bevel gear 75. Two second guide rods 71 ​​are provided, located on either side of the first screw 31 and fixedly connected to the inner wall of the outer casing 1. The L-shaped mounting plate 72 is fixedly sleeved on the outside of the two second guide rods 71. The drive block 73 is slidably sleeved on the outside of the two second guide rods 71 ​​and located in front of the L-shaped mounting plate 72. The second screw 74 passes through the drive block 73 and is threadedly connected to it. Two bevel gears 75 are provided, one fixedly sleeved on the rear end of the second screw 74, and the other fixedly sleeved on the top of the first screw 31. The two bevel gears 75 mesh with each other.

[0051] like Figure 3 and Figure 5 As shown, the trigger-type ink spraying mechanism 8 includes a spraying plate 81 and two sets of trigger-type ink spraying components. Each set of trigger-type ink spraying components includes a rigid tube 82, a first flexible tube 83, a connecting block 84, a second flexible tube 85, a T-shaped plate 86, a through hole 87, and two second springs 88. The spraying plate 81 is located at the top inside the shielding cover 51. The rigid tube 82 is fixedly installed through the top of the spraying plate 81 and passes through the L-shaped mounting plate 72 and is fixedly connected to the L-shaped mounting plate 72. The first flexible tube 83 is fixedly connected to the top of the rigid tube 82. The connecting block 84 is fixedly sleeved on the outer end of the first flexible tube 83 and fixedly connected to the inner wall of the side plate 2. The second flexible tube 85 is fixedly inserted through the connecting block 84 on the side away from the first flexible tube 83. The T-shaped plate 86 is slidably inserted through the top of the connecting block 84. The through hole 87 is inserted through the T-shaped plate 86. The two second springs 88 are respectively fixedly connected to the top two sides of the connecting block 84 and are both fixedly connected to the T-shaped plate 86.

[0052] By setting the above-mentioned spraying drive mechanism 7 and trigger-type ink spraying mechanism 8, the second spring 88 is stretched after the T-shaped plate 86 moves upward. When the through hole 87 gradually moves between the second hose 85 and the first hose 83, the ink inside the second hose 85 passes through the through hole 87 and enters the first hose 83. Then, it enters the spraying plate 81 through the rigid tube 82 and is finally sprayed out through multiple spraying holes at the bottom of the spraying plate 81. At the same time, during the rotation of the first screw 31, the second screw 74 is continuously driven to rotate through the bevel gear 75. When the second screw 74 rotates, it drives the drive block 73 to reciprocate back and forth. When the drive block 73 moves, it drives the spraying plate 81 to reciprocate back and forth through the rigid tube 82, thereby enabling the spraying plate 81 to perform interference spraying on the top of the semi-rigid flexible plate. Example

[0053] The method specifically includes the following steps:

[0054] S1. Print and expose flexible plate ink, then transport the semi-rigid flexible plate to the top of the lifting mechanism 3 via a conveyor belt. Then, the drive motor drives the first screw 31 to rotate. When the first screw 31 rotates, it drives the drive plate 32 to rise continuously. The drive plate 32 drives the lifting plate 35 to rise continuously. When the drive plate 32 rises to the first threshold, the lifting plate 35 contacts the semi-rigid flexible plate. Subsequently, as the lifting plate 35 continues to rise, the semi-rigid flexible plate on the conveyor belt is lifted upward by the lifting plate 35.

[0055] S2. When the rising distance of the drive plate 32 reaches the second threshold, the lifting plate 35 contacts the four positioning plates 54. At this time, the semi-rigid flexible plate moves between the four positioning plates 54. When the lifting plate 35 continues to rise, the lifting plate 35 pushes the four positioning plates 54, and the positioning plates 54 slide upward along the inclined inner wall of the shield 51.

[0056] S3. When the drive plate 32 rises to the third threshold, the inner slider 53 moves to the top of the inner side of the longitudinal slide groove 52. At this time, the semi-rigid flexible plate arrives at the spraying station. At the same time, the four positioning plates 54 contact each other from head to tail and complete the positioning of the semi-rigid flexible plate from all sides. Meanwhile, the ends of the two shielding plates 56 contact each other and form a shielding area on the top of the semi-rigid flexible plate.

[0057] S4. Since the lifting plate 35 cannot continue to rise, as the first screw 31 continues to rotate, the drive plate 32 cooperates with the lifting plate 35, causing the telescopic rod 34 to shorten. At this time, the first spring 36 is compressed, and the outer shaft of the telescopic rod 34 drives the trigger rod 42 to continue to rise through the connecting plate 41.

[0058] S5. When the drive plate 32 rises to the fourth threshold, the trigger rod 42 pushes the T-shaped plate 86, the T-shaped plate 86 moves up and stretches the second spring 88. When the drive plate 32 rises to the fifth threshold, the through hole 87 gradually moves between the second hose 85 and the first hose 83. The ink inside the second hose 85 passes through the through hole 87 and enters the first hose 83. Then it enters the spray plate 81 through the rigid tube 82 and is finally sprayed out through multiple spray holes at the bottom of the spray plate 81.

[0059] S6. During the rotation of the first screw 31, the second screw 74 is continuously driven to rotate through the bevel gear 75. When the second screw 74 rotates, it drives the drive block 73 to reciprocate back and forth. When the drive block 73 moves, it drives the spray plate 81 to reciprocate back and forth through the rigid tube 82, thereby enabling the spray plate 81 to perform interference spraying on the top of the semi-rigid flexible plate.

[0060] S7. During the interference spraying process, some ink falls on the top of the four positioning plates 54 and the top of the two baffle plates 56. The ink falling on the top of the baffle plates 56 flows to the top of the positioning plates 54 under the guidance of the guide groove 57. The ink on the top of the positioning plates 54 moves towards the recovery branch pipe 64 under the push of the scraper 63 driven by the electric slider 62, and is finally sucked out by the recovery main pipe 65 through the recovery branch pipe 64.

[0061] S8. After the spraying is completed, the drive motor drives the first screw 31 to rotate in the opposite direction, so that the sprayed semi-rigid flexible plate falls onto the conveyor belt and is output. At the same time, the next semi-rigid flexible plate to be sprayed is also conveyed to the top of the lifting mechanism 3 while the current semi-rigid flexible plate is output.

[0062] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.

8. A method for improving exposed copper at semi-rigid-flexible plate connections, implemented using the fabrication equipment for improving exposed copper at semi-rigid-flexible plate connections as described in any one of claims 1-7, characterized in that... The method specifically includes the following steps: S1. Print and expose flexible plate ink, then transport the semi-rigid flexible plate to the top of the lifting mechanism (3) via a conveyor belt. Then drive the first screw (31) to rotate. When the first screw (31) rotates, it drives the drive plate (32) to rise continuously. The drive plate (32) then drives the lifting plate (35) to rise continuously. When the drive plate (32) rises to the first threshold, the lifting plate (35) contacts the semi-rigid flexible plate. Subsequently, as the lifting plate (35) continues to rise, the semi-rigid flexible plate on the conveyor belt is lifted upward by the lifting plate (35). S2. When the rising distance of the drive plate (32) reaches the second threshold, the lifting plate (35) contacts the four positioning plates (54). At this time, the semi-rigid plate moves between the four positioning plates (54). When the lifting plate (35) continues to rise, the lifting plate (35) pushes the four positioning plates (54), and the positioning plates (54) slide upward along the inclined inner wall of the shield (51). S3. When the drive plate (32) rises to the third threshold, the inner slider (53) moves to the top of the inner side of the longitudinal slide groove (52). At this time, the semi-rigid flexible plate arrives at the spraying station. At the same time, the four positioning plates (54) contact each other from head to tail and complete the positioning of the semi-rigid flexible plate from all sides. Meanwhile, the ends of the two shielding plates (56) contact each other and form a shielding area on the top of the semi-rigid flexible plate. S4. Since the lifting plate (35) cannot continue to rise, as the first screw (31) continues to rotate, the drive plate (32) cooperates with the lifting plate (35) to shorten the telescopic rod (34). At this time, the first spring (36) is compressed, and the outer shaft of the telescopic rod (34) drives the trigger rod (42) to rise continuously through the connecting plate (41). S5. When the drive plate (32) rises to the fourth threshold, the trigger rod (42) pushes the T-shaped plate (86), the T-shaped plate (86) moves up and stretches the second spring (88). When the drive plate (32) rises to the fifth threshold, the through hole (87) gradually moves between the second hose (85) and the first hose (83). The ink inside the second hose (85) passes through the through hole (87) and enters the first hose (83). Then it enters the spray plate (81) through the hard tube (82) and is finally sprayed out through the multiple spray holes at the bottom of the spray plate (81). S6. During the rotation of the first screw (31), the second screw (74) is continuously driven to rotate through the bevel gear (75). When the second screw (74) rotates, it drives the drive block (73) to move back and forth. When the drive block (73) moves, it drives the spray plate (81) to move back and forth through the rigid tube (82), thereby enabling the spray plate (81) to perform interference spraying on the top of the semi-rigid flexible plate. S7. During the interference spraying process, some ink falls on the top of the four positioning plates (54) and the top of the two shielding plates (56). The ink on the top of the shielding plates (56) flows to the top of the positioning plates (54) under the guidance of the guide groove (57). The ink on the top of the positioning plates (54) moves towards the recovery branch pipe (64) under the push of the scraper (63) driven by the electric slider (62), and is finally sucked out by the recovery main pipe (65) through the recovery branch pipe (64). S8. After the spraying is completed, the drive motor drives the first screw (31) to rotate in the opposite direction, so that the sprayed semi-rigid flexible plate falls onto the conveyor belt and is output. At the same time, the next semi-rigid flexible plate to be sprayed is also conveyed to the top of the lifting mechanism (3) while the current semi-rigid flexible plate is output.
