Description

Technical Field

[0001] This invention relates to the field of circuit board processing technology, and more specifically to a circuit board developing device and method. Background Technology

[0002] During the current circuit board manufacturing process, a layer of photosensitive solder resist is usually evenly applied to the surface of the PCB board first. Then, the PCB board is exposed to light and undergoes a photochemical reaction. Afterward, the unexposed solder resist is reacted and dissolved by spraying or soaking in a developing solution, thereby revealing the circuit pattern on the PCB board.

[0003] For example, Chinese patent CN222071052U discloses a circuit board developing device. The device is equipped with a ring conveyor that drives the circuit board to move. The developing solution is sprayed out through the spray nozzle by rotating the nozzle, spraying the upper and lower surfaces of the circuit board.

[0004] However, after the circuit board is sprayed, the surface developer solution needs to be cleaned in time to avoid over-development and excessive etching of the pattern. After the circuit board is developed, the device has difficulty in automatically and orderly unloading the developed circuit board, which is inconvenient for subsequent movement, storage or processing (such as photoresist curing).

[0005] Based on this, the present invention designs a circuit board developing device and method to solve the above problems. Summary of the Invention

[0006] In view of the above-mentioned shortcomings of the prior art, the present invention provides a circuit board developing device and method.

[0010] Furthermore, the adjustable transfer module includes a mounting platform, a rotating support platform, a rotating frame, a second roller conveyor, two side retaining wheels, and a rotating cylinder. The mounting platform is fixedly mounted on the machine base, and the rotating support platform is fixedly mounted on the mounting platform. The rotating cylinder is rotatably mounted on the mounting platform. One end of the rotating frame is rotatably connected to the rotating support platform, and the other end of the rotating frame is rotatably connected to the output end of the rotating cylinder. The second roller conveyor is fixedly mounted on the rotating frame, and multiple second side retaining wheels are rotatably mounted at equal intervals on one side of the rotating frame near the rotating support platform.

[0011] Furthermore, the horizontal conveying module includes a horizontal support frame, roller conveyor three, and roller conveyor four. The horizontal support frame is fixedly installed on the machine platform. Roller conveyor three is fixedly installed on the left side of the horizontal support frame, and roller conveyor four is fixedly installed on the right side of the horizontal support frame. Roller conveyor four is located below the docking module.

[0012] Furthermore, the vertical material transfer module includes a baffle, a vertical straight module, and a moving plate. The baffle is fixedly installed on the left side of the unloading mounting frame, the vertical straight module is fixedly installed on the unloading mounting frame, and the moving end of the vertical straight module is fixedly installed with a moving plate.

[0013] Furthermore, the docking module includes a docking cylinder, a rotating rod, a connecting rod, guide rails, and a docking hook plate. The docking cylinder is rotatably mounted on the lower side of the moving plate, and the middle part of the rotating rod is rotatably mounted on the lower side of the moving plate. The output end of the docking cylinder is rotatably connected to one end of the rotating rod. Four guide rails are symmetrically fixedly mounted on the lower side of the moving plate.

[0016] To better achieve the objectives of this invention, this invention also provides a circuit board developing method using a circuit board developing apparatus, comprising the following steps: Step 1: Move a material rack to the lower side of the docking module, connect the material rack through the docking module, stabilize the material rack through the stabilizing module, and then the vertical material transfer module drives the material rack to move vertically through the docking module, so that the material trough on the uppermost side of the material rack is aligned with the horizontal conveying module. Step 2: The circuit board moves from left to right at an angle on the tilting conveyor module. The developing solution is sprayed onto the circuit board by the spray module to make the circuit board pattern appear. Water is sprayed onto the circuit board by the cleaning module to clean the residual developing solution on the circuit board. Then the drying module dries the circuit board. Step 3: The developed circuit board is transported by the inclined conveyor module to the adjustable transfer module. The adjustable transfer module moves the circuit board to make it horizontal, and then the adjustable transfer module transports the circuit board to the horizontal conveyor module, which in turn transports the circuit board to the material slot on the material rack. The vertical transfer module drives the material rack to move vertically through the docking module, so that the empty material slot on the material rack is aligned with the horizontal conveyor module. Step 4: Repeat steps 2 and 3 until all the material tanks are filled with the circuit board.

[0017] Compared to existing technologies, the advantages of this invention are as follows: A material rack is moved to the lower side of the docking module, connected to the material rack via the docking module, and stabilized by a stabilizing module. Then, a vertical material transfer module drives the material rack vertically via the docking module, aligning the uppermost material container of the material rack with the horizontal conveying module. The circuit board moves from left to right at an angle on the inclined conveying module, passing sequentially through a spraying module, a cleaning module, and a drying module. This process reveals the circuit board pattern and cleans away any residual developer solution. The drying module then dries the circuit board. After development, the circuit board is conveyed by the inclined conveying module to an adjustable transfer module, which moves the circuit board horizontally. The rear-adjustable transfer module transports the circuit boards to the horizontal conveyor module, which then transfers them into the storage slots on the rack. The vertical transfer module, via the docking module, moves the rack vertically, aligning any empty storage slots with the horizontal conveyor module. This process is repeated until all storage slots are filled with circuit boards. At this point, the rack moves to the top of the unloading mounting frame, where the docking and stabilizing modules are reset. The rack filled with circuit boards is then removed. Simultaneously, an empty rack is moved to the bottom of the docking module, where it is secured by the docking and stabilizing modules. This continuous process of developing, cleaning, drying, and stacking the circuit boards ensures high overall development efficiency. Attached Figure Description

[0023] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-3 A circuit board developing device includes a machine base 1 and a material rack 5; it also includes a conveying mechanism 2, a developing mechanism 3 and an automatic palletizing and unloading mechanism 4; The machine base 1 is equipped with a conveying mechanism 2 and a developing mechanism 3 on the left side, and an automatic stacking and unloading mechanism 4 for driving the material rack 5 to move vertically is installed on the right side of the machine base 1; the material rack 5 is evenly spaced with multiple material troughs 51 for accommodating circuit boards. like Figure 2 As shown, the conveying mechanism 2 includes an inclined conveying module 21, an adjustable transfer module 22, and a horizontal conveying module 23, which are installed sequentially from left to right on the machine base 1; the right end of the horizontal conveying module 23 is located below the automatic palletizing and unloading mechanism 4; the horizontal conveying module 23 is used to convey the developed circuit boards to the material rack 5; like Figure 2 As shown, the developing mechanism 3 includes a spray module 31, a cleaning module 32, a drying module 33, and a collection box 34.

Then, the vertical material transfer module 42 drives the material rack 5 to move vertically through the docking module 43, so that the material receiving trough 51 on the uppermost side of the material rack 5 is aligned with the horizontal conveying module 23.

After development, the circuit board is conveyed by the tilting conveyor module 21 to the adjustable transfer module 22. The adjustable transfer module 22 moves the circuit board to make it horizontal. Then, the adjustable transfer module 22 conveys the circuit board to the horizontal conveyor module 23, which conveys the circuit board into the material slot 51 on the material rack 5.

At the same time, the empty material rack 5 is moved to the lower side of the unloading mounting frame 41 and the docking module 43 and the stabilizing module 44 are used to fix the material rack 5. In this way, the circuit boards are continuously developed, cleaned, dried and stacked to ensure the overall development efficiency of the circuit boards.

[0028] like Figure 4 and Figure 8 As shown, a partition plate 411 is fixedly installed on the middle right side of the unloading mounting frame 41. Empty material racks 5 move from the lower side of the partition plate 411 to the lower side of the docking module 43, and material racks 5 filled with circuit boards move out from the upper side of the partition plate 411.

[0029] The vertical material transfer module 42 includes a baffle 421, a vertical straight module 422, and a moving plate 423. The baffle 421 is fixedly installed on the left side of the unloading mounting frame 41, the vertical straight module 422 is fixedly installed on the unloading mounting frame 41, and the moving end of the vertical straight module 422 is fixedly installed with the moving plate 423. The docking module 43 includes a docking cylinder 431, a rotating rod 432, a connecting rod 433, a guide rail 434, and a docking hook plate 435. The docking cylinder 431 is rotatably mounted on the lower side of the moving plate 423, and the middle part of the rotating rod 432 is rotatably mounted on the lower side of the moving plate 423. The output end of the docking cylinder 431 is rotatably connected to one end of the rotating rod 432. Four guide rails 434 are symmetrically fixedly mounted on the lower side of the moving plate 423.

[0031] In this embodiment, when the conveying mechanism 2, developing mechanism 3, automatic palletizing and unloading mechanism 4, and material rack 5 are working normally, one material rack 5 is moved to the lower side of the moving plate 423. The vertical linear module 422 drives the moving plate 423 to move vertically downward, thereby driving the guide rail 434 and the first docking hook plate 435 to move downward until the first docking hook plate 435 aligns with the second docking hook plate 52. The docking cylinder 431 drives the rotating rod 432 to rotate, thereby synchronously driving the first docking hook plates 435 on both sides through the connecting rods 433 on both sides of the rotating rod 432. The first docking hook plate 435 moves horizontally under the limiting action of the guide rail 434, so that the first docking hook plate 435 is inserted into the second docking hook plate 52; then the positioning cylinder 441 drives the pressure plate 442 to move down, so that the pressure plate 442 presses against the pad 53 on the top of the material rack 5, making the material rack 5 more stable; the vertical linear module 422 drives the material rack 5 to move vertically through the moving plate 423, the guide rail 434, the first docking hook plate 435 and the second docking hook plate 52, so that the uppermost material receiving trough 51 of the material rack 5 is aligned with the roller conveyor 4233; The circuit board moves from left to right at an angle on the roller conveyor 212. The roller conveyor 212 is tilted by the inclined support frame 211, and the side stop roller 213 blocks the side of the circuit board on the roller conveyor 212 to prevent the circuit board from slipping. The circuit board passes through the nozzle 314, the cleaning module 32 and the drying module 33 in sequence. The developing solution is sprayed onto the circuit board through the connecting pipe 312, the conveying pipe 313 and the nozzle 314, so that the pattern on the circuit board appears. During this process, the developing solution flows along the inclined circuit board into the collection box 34 and is collected by the collection box 34. Water is sprayed onto the circuit board through the cleaning module 32 to clean the residual developing solution on the circuit board, and then the drying module 33 dries the circuit board. After development, the circuit board is conveyed by roller conveyor 212 to roller conveyor 224. The side stop roller 225 blocks the side of the circuit board to prevent it from slipping. Then, the rotating cylinder 226 drives the rotating frame 223 to rotate, thereby driving roller conveyor 224 and side stop roller 225 to rotate, so that roller conveyor 224 and roller conveyor 322 are on the same horizontal plane. Roller conveyor 224 moves the circuit board to roller conveyor 322. Roller conveyor 322 moves the circuit board to roller conveyor 433, and roller conveyor 433 moves the circuit board into the material receiving trough 51. Then, the vertical linear module 422 moves the guide rail 434 and docking hook plate 435 upward through the moving plate 423, so that the empty material receiving trough 51 on the material rack 5 is aligned with roller conveyor 433. Repeat the above operation until all the material tanks 51 are filled with the circuit board.

[0032] Example 3: In some embodiments, such as Figures 1-9 As shown, in a preferred embodiment of the present invention, a circuit board developing method of a circuit board developing apparatus includes the following steps: Step 1: Move a material rack 5 to the underside of the moving plate 423. The vertical linear module 422 drives the moving plate 423 to move vertically downward, thereby driving the guide rail 434 and the first docking hook plate 435 to move downward until the first docking hook plate 435 aligns with the second docking hook plate 52. The docking cylinder 431 drives the rotating rod 432 to rotate, thereby synchronously driving the first docking hook plates 435 on both sides to move through the connecting rods 433 on both sides of the rotating rod 432. The first docking hook plate 435 moves along the guide rail 434. Under the limiting action of rail 434, the horizontal movement causes the first docking hook plate 435 to be inserted into the second docking hook plate 52; then the positioning cylinder 441 drives the pressure plate 442 to move down, so that the pressure plate 442 presses against the pad 53 at the top of the material rack 5; the vertical linear module 422 drives the material rack 5 to move vertically through the moving plate 423, guide rail 434, first docking hook plate 435 and second docking hook plate 52, so that the uppermost material receiving trough 51 of the material rack 5 is aligned with the roller conveyor 4233; Step Two: The circuit board moves from left to right on the roller conveyor 212 at an angle. The roller conveyor 212 is tilted by the inclined support frame 211, and the side stop roller 213 blocks the side of the circuit board on the roller conveyor 212. The circuit board passes through the nozzle 314, the cleaning module 32, and the drying module 33 in sequence. The developing solution is sprayed onto the circuit board through the connecting pipe 312, the conveying pipe 313, and the nozzle 314, making the circuit board pattern visible. During this process, the developing solution flows along the tilted circuit board into the collection box 34 and is collected. Water is sprayed onto the circuit board through the cleaning module 32 to clean the residual developing solution on the circuit board, and then the drying module 33 dries the circuit board. Step 3: The developed circuit board is conveyed by roller conveyor 212 to roller conveyor 224, where the side stop roller 225 blocks the side of the circuit board. Then, the rotating cylinder 226 drives the rotating frame 223 to rotate, thereby driving roller conveyor 224 and side stop roller 225 to rotate, so that roller conveyor 224 and roller conveyor 322 are on the same horizontal plane. Roller conveyor 224 moves the circuit board to roller conveyor 322. Roller conveyor 322 moves the circuit board to roller conveyor 433, and roller conveyor 433 moves the circuit board into the material receiving trough 51. Then, the vertical linear module 422 moves the guide rail 434 and docking hook plate 435 upward through the moving plate 423, so that the empty material receiving trough 51 on the material rack 5 is aligned with roller conveyor 433. Step 4: Repeat steps 2 and 3 until all the material tanks 51 are filled with the circuit board.
