[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0033] Example 1, please refer to Figures 1-11 The present invention discloses a circuit board printing and manufacturing device, including a conveyor belt 1. One end of the conveyor belt 1 is provided with a plate placing device 11 for storing copper clad laminates that need to be coated with solder resist ink. One side of the plate placing device 11 is provided with two coating devices 12. Between the two coating devices 12 is provided a fixed plate 2. The fixed plate 2 is fixedly installed on the fixed installation plate of the conveyor belt 1. A square rod 34 is arranged between the fixed plates 2. One end of the square rod 34 is rotatably connected to a gear 33. The other side of the gear 33 is fixedly connected to a sliding square block 317. The other end of the sliding square block 317 is slidably connected to a clamping block 3. Through the design of the sliding square block 317, when the gear 33 rotates, the clamping block 3 can be driven to rotate through the sliding square block 317. One side of the clamping block 3 is communicated with an air pipe 31 for adsorbing the copper clad laminate 5. Through the design of the air pipe 31, suction can be provided for the clamping block 3, so that the clamping block 3 can adsorb the copper clad laminate 5. A torsion spring 35 is sleeved outside the square rod 34. One end of the torsion spring 35 is fixedly connected to the square rod 34, and the other end of the torsion spring 35 is fixedly connected to the gear 33. Fixed holes 32 are arranged on both sides of the gear 33;

[0034] A hydraulic rod 310 is slidably connected below the square rod 34. The hydraulic rod 310 is fixedly installed on the fixed plate 2.

[0035] On one side of the fixed plate 2, a first vertical sliding groove 21, a first inclined sliding groove 22, a second vertical sliding groove 23 and a second inclined sliding groove 24 are provided. The first vertical sliding groove 21, the first inclined sliding groove 22, the second vertical sliding groove 23 and the second inclined sliding groove 24 communicate with each other. A limiting sliding groove 210 is provided on the other side of the fixed plate 2.

[0036] On the other side of the fixed plate 2, a sliding rack 315 is slidably connected. The fixed plate 2 will not be separated from the sliding rack 315. The sliding rack 315 is L-shaped. One side of the sliding rack 315 is meshed and connected with a gear 33. One end of the sliding rack 315 is fixedly connected with a first spring 316. The other end of the first spring 316 is fixedly connected with the fixed plate 2.

[0037] One end of a square rod 34 is slidably connected with a sliding limiting rod 29. The other end of the sliding limiting rod 29 is fixedly connected with a slider 26. One side of one end of the slider 26 is provided with a first sliding column 27. One side of the other end of the slider 26 is fixedly connected with a sliding fixing rod 28. The sliding fixing rod 28 is slidably connected with a fixing hole 32.

[0038] The first sliding column 27 is slidably connected with the first vertical sliding groove 21, the first inclined sliding groove 22, the second vertical sliding groove 23 and the second inclined sliding groove 24.

[0039] On the other side of the fixed plate 2, a first sliding track 311, a first inclined sliding track 312, a second sliding track 313 and a second inclined sliding track 314 are provided. The first sliding track 311, the first inclined sliding track 312, the second sliding track 313 and the second inclined sliding track 314 communicate with each other. A sliding groove 25 is provided between the first vertical sliding groove 21 and the second sliding track 313. The sliding groove 25 is provided on the fixed plate 2. Through the design of the sliding groove 25, the sliding fixing rod 28 can slide up and down together with the slider 26, preventing the fixed plate 2 from jamming the sliding of the slider 26.

[0040] One side of one end of the square rod 34 is fixedly connected with a second sliding column 36. The second sliding column 36 is slidably connected with the first sliding track 311, the first inclined sliding track 312, the second sliding track 313 and the second inclined sliding track 314.

[0041] First, place the copper clad laminate 5 that needs to be coated with solder mask ink into the plate placing device 11. Subsequently, through the plate placing device 11, place the copper clad laminates 5 one by one on the conveyor belt 1, and convey the copper clad laminates 5 through the conveyor belt 1. Convey the copper clad laminate 5 to the lower part of the coating device 12, and coat one side of the copper clad laminate 5 with solder mask ink through the coating device 12. After one side of the copper clad laminate 5 is coated, the conveyor belt 1 continues to move the copper clad laminate 5. When the copper clad laminate 5 moves to the clamping blocks 3, the clamping blocks 3 on both sides generate gas through the air pipes 31 to adsorb the copper clad laminate 5, so that the copper clad laminate 5 can be fixed between the two clamping blocks 3. It should be noted that the adsorption and clamping of the plate placing device 11, the coating device 12 and the clamping blocks 3 are prior arts, and professionals in this field can freely select according to the actual situation.

[0042] After fixing the copper clad laminate 5, start the hydraulic rod 310. Drive the square rod 34 to slide upward through the hydraulic rod 310. While the square rod 34 slides upward, drive the gear 33, the clamping block 3 and the copper clad laminate 5 to slide upward together. While the square rod 34 slides upward, the second sliding column 36 will slide in the first inclined slideway 312. When the second sliding column 36 slides in the first inclined slideway 312, it will drive the square rod 34 and the gear 33 to slide to the left, so that the gear 33 slides below the sliding rack 315. When the second sliding column 36 slides in the second slideway 313, as the square rod 34 drives the second sliding column 36 to continue sliding upward, the gear 33 will mesh with the sliding rack 315. Through the meshing of the 33 sliding rack 315, the gear 33 drives the sliding block 317 and the clamping block 3 to rotate together, and drives the copper clad laminate 5 to rotate together through the rotation of the clamping block 3;

[0043] It should be noted that after the second sliding column 36 slides from the first inclined slideway 312 into the second slideway 313 and the gear 33 is about to mesh with the sliding rack 315, the first sliding column 27 slides from the lower end of the first vertical chute 21 into the first inclined chute 22. Through the guidance of the first inclined chute 22 on the first sliding column 27, the slider 26 drives the sliding fixed rod 28 to slide together. Through the sliding of the sliding fixed rod 28, the sliding fixed rod 28 slides out of the fixing hole 32, so that the position of the clamping block 3 is not restricted, which is convenient for the gear 33 to drive the clamping block 3 to rotate when meshing with the sliding rack 315 subsequently.

[0044] After the clamping block 3 drives the copper clad laminate 5 to complete the flipping, at this time, the gear 33 is still in the meshed state with the sliding rack 315, and at the same time, one side of the gear 33 abuts against the L-shaped rod of the sliding rack 315 at this time. Through such a design, the position of the clamping block 3 can be fixed, preventing the gear 33 from rotating and driving the clamping block 3 to rotate together. When the gear 33 pushes the sliding rack 315 to slide upward, at this time, the first sliding column 27 slides in the second inclined chute 24, so that the first sliding column 27 drives the slider 26 and the sliding fixing rod 28 to slide together, so that one end of the sliding fixing rod 28 slides into the fixing hole 32 to realize the fixation of the clamping block 3; after the sliding fixing rod 28 slides into the fixing hole 32, at this time, the second sliding column 36 slides from the sliding rack 315 into the second inclined chute 314. Through the guidance of the second inclined chute 314 on the second sliding column 36, the second sliding column 36 can drive the gear 33 to slide to the right. Through the rightward sliding of the gear 33, the gear 33 slides past the sliding rack 315, so that the sliding rack 315 returns to its original position under the action of the first spring 316.

[0045] It should be noted that through the design of the L-shaped sliding rack 315, after the gear 33 drives the clamping block 3 to complete the flipping, the gear 33 still meshes with the sliding rack 315, so that the position of the gear 33 can be fixed, preventing the gear 33 from reversing under the action of the torsion spring 35. As the gear 33 continues to slide upward, the sliding fixing rod 28 slides into the fixing hole 32. After the position of the clamping block 3 is fixed, the gear 33 begins to slide to the right and disengages from the sliding rack 315, so that the position of the copper clad laminate 5 can be fixed after flipping. Through such a design, when the hydraulic rod 310 drives the clamping block 3 to slide downward, the gear 33 does not mesh with the sliding rack 315, preventing the reversed copper clad laminate 5 from reversing; finally, the copper clad laminate 5 is placed back on the conveyor belt 1.

[0046] Through the sliding of the sliding rack 315 and the design of the first spring 316, after the gear 33 meshes with the sliding rack 315 and drives the copper clad laminate 5 to flip, as the gear 33 continues to slide upward, one side of the gear 33 will abut against the L-shaped rod at the upper end of the sliding rack 315, so that the gear 33 drives the sliding rack 315 to slide upward together, and at the same time, the first spring 316 is deformed to provide power for the subsequent reset of the sliding rack 315. Through such a design, the gear 33 can always mesh with the sliding rack 315, so that the position of the gear 33 can always be fixed, preventing the gear 33 from rotating.

[0047] In this embodiment: During the process of applying the solder mask ink to the copper clad laminate 5, by driving the gear 33, the clamping block 3 and the copper clad laminate 5 are driven to complete automatic flipping. Through the drive of the hydraulic rod 310, the cooperation between the first sliding column 27 and the first inclined chute 22, the second sliding column 36 and the first inclined slideway 312, and the meshing mechanism between the gear 33 and the L-shaped sliding rack 315, it not only ensures that the copper clad laminate can be smoothly flipped to apply the other side after one side is applied, but also after the flipping is completed, the position of the copper clad laminate 5 is effectively fixed by the cooperation between the sliding fixing rod 28 and the fixing hole 32, preventing the position change caused by the reverse rotation of the gear 33, thereby improving the accuracy and efficiency of the application. Further, when the copper clad laminate 5 is applying the solder mask ink, it can be evenly applied on the surface of the copper clad laminate 5.

[0048] Embodiment 2. The purpose of this embodiment is to facilitate the solution of the problem that dust may adhere to the copper clad laminate 5 during the flipping process, which affects the application of the solder mask ink. This embodiment is an improvement based on Embodiment 1. Specifically, on the other side of one end of the square rod 34, a connecting rod 37 is fixedly connected. One end of the connecting rod 37 is fixedly connected with a sealing piece 38. The sealing piece 38 is slidably connected with a sealing chamber 39. The sealing chamber 39 is slidably connected with the limiting chute 210. One end of the sealing chamber 39 is communicated with a pipeline 44. A one-way valve 45 communicating with the outside is arranged on the sealing chamber 39, and a one-way valve 45 is also arranged in the pipeline 44.

[0049] One end of the pipeline 44 is communicated with a pair of fixing blocks 4. The two fixing blocks 4 are respectively located on the upper and lower sides of the clamping block 3. An inclined groove 42 is opened inside the fixing block 4. The inclined groove 42 is designed to be enlarged from top to bottom. A sealing ball 43 is arranged inside the inclined groove 42. A blowing port 41 is arranged on the fixing block 4. The blowing port 41 is communicated with the inclined groove 42.

[0050] When the second sliding column 36 slides in the second inclined slideway 314 and drives the square rod 34 to slide to the right, it will drive the connecting rod 37 to slide to the right together. By the rightward sliding of the connecting rod 37, the sealing piece 38 will slide in the sealing chamber 39. Through the extrusion of the air in the sealing chamber 39 by the sealing piece 38, the gas in the sealing chamber 39 flows into the inclined groove 42 through the pipeline 44. It should be noted that see Figure 11 , when the fixing block 4 flips together with the clamping block 3, the sealing ball 43 in the upper fixing block 4 will fall into the large groove of the inclined groove 42 due to gravity, and at the same time, the sealing ball 43 in the lower fixing block 4 will be stuck in the small groove of the inclined groove 42, so that the gas can only be blown out from the upper blowing port 41, and the lower inclined groove 42 will be blocked by the sealing ball 43; it should be noted that the one-way valve 45 on the sealing chamber 39 only allows air to enter and not to exit, and at the same time, the one-way valve 45 on the pipeline 44 only allows the gas in the sealing chamber 39 to enter the pipeline 44, and the gas in the pipeline 44 cannot enter the sealing chamber 39.

[0051] In this embodiment: by sealing the inclined groove 42 with the sealing ball 43, only the air path in the upper fixed block 4 is unobstructed, so that the surface of the copper clad laminate 5 is blown only after the copper clad laminate 5 is turned over, so that the dust attached to the copper clad laminate 5 can be blown away during the turning process, and at the same time, by closing the lower air path, the gas can only flow out through the upper blowing port 41, which can prevent the loss of gas, so that the surface of the copper clad laminate 5 can be blown cleaner, and further, when the copper clad laminate 5 is coated with solder resist ink, it can be evenly applied on the surface of the copper clad laminate 5.

[0052] Embodiment 3: This embodiment is intended to promote the solution of the problem that the first sliding column 27 and the second sliding column 36 do not slide along the predetermined track during the sliding process. This embodiment is an improvement made on the basis of Embodiment 2. For details, please refer to Figures 1-11 A limiting mechanism 6 is provided at the junction of the first vertical slide groove 21 and the first inclined slide groove 22, and the limiting mechanism 6 includes a blocking inclined block 61 slidably connected to the fixed plate 2, and a second spring 62 is provided between the blocking inclined block 61 and the fixed plate 2. A limiting mechanism 6 is provided at the junction of the first vertical slide groove 21 and the second inclined slide groove 24, the junction of the first slide 311 and the first inclined slide 312, and the junction of the first slide 311 and the second inclined slide 314.

[0053] When the first sliding post 27 slides from bottom to top to the junction of the first vertical slide groove 21 and the first inclined slide groove 22, the first sliding post 27 will conflict with the straight surface of the blocking oblique block 61, so that the first sliding post 27 can only slide into the first inclined slide groove 22. When the first sliding post 27 slides from top to bottom, the first sliding post 27 will first conflict with the inclined surface on the blocking oblique block 61, squeezing the blocking oblique block 61 so that the blocking oblique block 61 can slide into the fixed plate 2, thereby opening the first vertical slide groove 21, so that the first sliding post 27 can slide to the lower end of the first vertical slide groove 21. When the first sliding post 27 slides over the blocking oblique block 61, the blocking oblique block 61 is in the second Under the action of the spring 62, the blocking bevel 61 will be driven to return to its original position; it should be noted that the blocking bevel 61 at the junction of the first vertical slide groove 21 and the second inclined slide groove 24 prevents the first sliding column 27 from sliding out of the second inclined slide groove 24 and then sliding back into the second inclined slide groove 24, and the blocking bevel 61 at the junction of the first slide 311 and the first inclined slide 312 prevents the second sliding column 36 from sliding into the first slide 311 first when the second sliding column 36 slides upward, and at the same time, the blocking bevel 61 at the junction of the second inclined slide 314 and the first slide 311 prevents the second sliding column 36 from sliding back into the second inclined slide 314 when the second sliding column 36 slides downward.

[0054] It should be noted that when the first sliding post 27 slides from the first vertical slide groove 21 into the first inclined slide groove 22, the first sliding post 27 drives the slider 26 to slide to the left through the guidance of the first inclined slide groove 22, so that the slider 26 drives the sliding fixing rod 28 to slide out of the fixing hole 32, so that the clamping block 3 is unlocked. At the same time, the second sliding post 36 slides in the first inclined slide 312, so that the gear 33 can slide to the bottom of the sliding rack 315, so that when the subsequent gear 33 slides upward, the gear 33 can mesh with the sliding rack 315, and at the same time, the sealing sheet 38 slides in the sealing chamber 39, and air is sucked from the outside into the sealing chamber 39 through the one-way valve 45 to prepare for subsequent blowing.

[0055] When the first sliding post 27 slides upward in the second vertical sliding groove 23, the second sliding post 36 slides upward in the second slideway 313. As the second sliding post 36 continues to slide upward, the gear 33 meshes with the sliding rack 315. Through the meshing of the gear 33 and the sliding rack 315, the gear 33 drives the clamping block 3 and the copper clad plate 5 to rotate. When the gear 33 contacts the rod at the upper end of the sliding rack 315, the copper clad plate 5 has completed the flipping. At the same time, as it continues to slide upward, the gear 33 will slide upward with the sliding rack 315, so that the gear 33 will not rotate, so that the position of the copper clad plate 5 can be fixed and will not deviate, causing the first spring 316 to deform. When sliding in the slide groove 24, the first sliding column 27 will drive the slider 26 and the sliding fixing rod 28 to slide to the right, so that the sliding fixing rod 28 slides into the fixing hole 32 again, so that the position of the clamping block 3 can be fixed to prevent the position of the copper clad plate 5 from being offset. It should be noted that the gear 33 will be separated from the sliding rack only after the fixing rod 28 is inserted into the fixing hole 32; at the same time, the second sliding column 36 will slide in the second inclined slideway 314, so that the square rod 34 slides to the right, and at the same time drives the sealing sheet 38 to squeeze the gas in the sealing chamber 39, so that the gas in the sealing chamber 39 can be blown out through the pipe 44 and the blowing port 41, so that the dust on the copper clad plate 5 after the flip can be blown away;

[0056] By sliding the square rod 34 to the right, the positions of the gear 33 and the sliding rack 315 are offset, so that the sliding rack 315 returns to its original position under the action of the first spring 316. At this time, the first sliding column 27 is in the first vertical slide groove 21, and the second sliding column 36 is in the first slideway 311. Then the hydraulic rod 310 starts to pull back to bring the copper clad laminate 5 back to the conveyor belt 1. Then the clamping block 3 releases the adsorption of the copper clad laminate 5, so that the copper clad laminate 5 can be conveyed to the next processing site by the conveyor belt 1.

[0057] In this embodiment: Through the design of multiple junction limiting mechanisms 6, during the sliding process of the first sliding column 27 and the second sliding column 36, they can slide along a predetermined trajectory, preventing the first sliding column 27 and the second sliding column 36 from getting out of control, enabling other components to operate normally, and enabling the flipping and air blowing of the copper clad laminate 5 to operate normally.

[0058] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0059] The above are only the preferred embodiments of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
