Description

Technical Field

[0001] This utility model relates to the field of automatic exposure technology, specifically to a fully automatic flipping exposure device. Background Technology

[0002] In recent years, with the rapid development of electronic technology, the PCB industry's demand for increased production capacity has surged. Traditional fully automatic exposure machines can only achieve a capacity of 3-3.5 pieces per minute in the solder resist exposure process, typically employing a single-sided exposure, single-frame operation design. In the past two years, some companies have changed their traditional design, adopting a single-sided exposure, double-frame operation design, achieving a capacity of 5-6 pieces per minute. Even so, this still cannot meet the ever-increasing demand of the current circuit board manufacturing industry.

[0003] Because both sides of the PCB board need to be exposed separately, after one side is exposed, a flipping mechanism is required to flip the board to expose the other side. Existing automated exposure equipment is too large in size, occupies a large area, has excessively long line-to-line (CT) operations, and has low overall capacity. The board exchange process is complex and requires two machines to expose both sides of the product. Moreover, traditional double-sided exposure machines are generally designed for fixed board types or sizes, or require manual adjustment of the pick-up or clamping mechanism to change the distance for several different sizes. This undoubtedly leads to poor equipment versatility and low efficiency. Summary of the Invention

It also includes a first transfer unit that can switch between these three stations. After the board passes through the feeding mechanism and is calibrated and positioned by the positioning mechanism, the robotic arm of the first transfer unit transfers the board to the first exposure device for exposure. After exposure, the flipping mechanism picks up and flips the board so that the unexposed side faces outwards. Simultaneously, the robotic arm picks up the unexposed side of the board and transfers it to the second exposure device for exposure.

Detailed Implementation

[0031] To facilitate understanding by those skilled in the art, the following description is provided in conjunction with embodiments and appendices. Figure 1-11 The present invention will be further described below. The content mentioned in the embodiments is not intended to limit the present invention.

[0032] See Figure 1-11 The purpose of this utility model is achieved through the following technical solution: a fully automatic flipping exposure device, including a feeding mechanism 1, the feeding mechanism 1 being used to transport the plate 9, and the discharge end of the feeding mechanism 1 being provided with a positioning mechanism 2;

[0033] The system comprises a first exposure device 4, a second exposure device 6, and a feeding mechanism 7. The first exposure device 4 is located on one side of the positioning mechanism 2, the second exposure device 6 is located on one side of the first exposure device 4, and the feeding mechanism 7 is located on one side of the second exposure device 6.

[0034] Flipping mechanism 5, which is used to obtain plate 9 from the first exposure device 4 so that the unexposed side of plate 9 is facing outward;

[0035] The first transfer unit 3 is movable between the positioning mechanism 2 and the first exposure device 4 to move the plate 9 from the positioning mechanism 2 to the first exposure device 4; the first transfer unit 3 is movable between the flipping mechanism 5 and the second exposure device 6 to expose the unexposed side of the plate 9 from the flipping mechanism 5 to the second exposure device 6; the first transfer unit 3 is movable between the second exposure device 6 and the unloading mechanism 7 to move the plate 9 from the second exposure device 6 to the unloading mechanism 7 for unloading; the first transfer unit 3 is a robotic arm, and the robotic arm is equipped with a fourth suction unit 31.

[0036] The surface exposure device in this embodiment includes a feeding mechanism 1, a positioning mechanism 2, a first exposure device 4, a second exposure device 6, a flipping mechanism 5, and a unloading mechanism 7. It also includes a first transfer unit 3 that can switch between the positioning mechanism 2, the first exposure device 4, the second exposure device 6, the flipping mechanism 5, and the unloading mechanism 7. During the exposure process, the feeding mechanism 1 first transports the board 9 to the positioning mechanism 2 for calibration and positioning. Then, a robotic arm transfers the board 9 to the first exposure device 4 for exposure. After exposure, the flipping mechanism 5 is activated to lift and flip the board 9 so that the unexposed side faces outwards. Simultaneously, the robotic arm holds the unexposed side of the board 9 and transfers it to the second exposure device 6 for exposure. After double-sided exposure, the robotic arm transfers the board 9 to the unloading mechanism 7 for unloading and stacking. The flipping mechanism 5 is provided in the first exposure device 4 and the second exposure device 6, enabling this fully automatic flipping exposure device to achieve double-sided exposure. Meanwhile, the use of two exposure devices in this scheme shortens the waiting time for the substrate 9 to be placed in, and allows for the re-feeding of new substrate 9 from the feeding device. During the first exposure of substrate 9 by the first exposure device 4, the feeding mechanism 1 transports the second substrate 9 to the positioning mechanism 2 for calibration and positioning. After the first substrate 9 is flipped by the flipping mechanism 5, the robot transfers it to the second exposure device 6 for exposure. The robot returns to its original position and transfers the second substrate 9 back to the first exposure device 4 for exposure. The robot returns to its original position and transfers the first substrate 9, which has completed double-sided exposure, from the second exposure device 6 to the unloading mechanism 7. At the same time, the second substrate 9 is flipped by the flipping mechanism 5 and transferred to the second exposure device 6 for exposure. This process is repeated until the double-sided exposure of the substrate 9 corresponding to the second exposure device 6 is completed. After this process, the substrate 9 corresponding to the first exposure device 4 can be quickly placed into the second exposure device 6, greatly improving the production capacity of the fully automatic flipping exposure device.

[0037] In this embodiment, the positioning mechanism 2 includes a mounting frame 21, a positioning frame 22, a transverse positioning mechanism 23, and a longitudinal positioning mechanism 24. The positioning frame 22 is provided with a plurality of evenly distributed positioning posts 25. The positioning frame 22 is movably mounted on the mounting frame 21, and the mounting frame 21 is provided with a first driving device 26 for driving the positioning frame 22 to rise and fall relative to the mounting frame 21. The transverse positioning mechanism 23 is provided with a movable first positioning element 231 and is located on one side of the positioning frame 22. The longitudinal positioning mechanism 24 is provided with a movable second positioning element 241 and is disposed on the mounting frame 21 and located on one side of the positioning frame 22.

[0038] In this embodiment, the lateral positioning mechanism 23 includes a first positioning element 231, a first base 232 and a first driving component 233. The first driving component 233 is disposed on the first base 232. The first positioning element 231 is connected to the first driving component 233, and the first driving component 233 can drive the first positioning element 231 away from or near the mounting bracket 21.

[0039] In this embodiment, the longitudinal positioning mechanism 24 includes a second positioning member 241, a second base 242, and a second driving component 243. The second base 242 is disposed on the mounting frame 21 and located on one side of the positioning frame 22. The second driving component 243 is disposed on the second base 242. The second positioning member 241 is connected to the second driving component 243, and the second driving component 243 can drive the second positioning member 241 away from or near the positioning frame 22.

[0040] In this embodiment, the positioning mechanism 2 adopts the specific structure described above. During positioning, the feeding mechanism 1 conveys the plate 9 to the positioning frame 22. The transverse positioning mechanism 23 can be used to limit the plate 9 to a transversely set position at the discharge end of the feeding mechanism 1. At the same time, combined with the longitudinal positioning mechanism 24, the plate 9 can be limited to a longitudinally set position at the discharge end of the feeding mechanism 1. Specifically, when the transverse positioning mechanism 23 is used for positioning, the first driving component 233 drives the first positioning member 231 to move laterally along the feeding direction of the plate 9 to the set position, and the first positioning member 231 can be used to limit the plate 9 to the set transverse position. Then, the transverse and longitudinal positioning mechanisms 24 are used for positioning. First, the second driving component 243 drives the second positioning member 241 to move laterally along the feeding direction of the plate 9. Moving vertically to the set position, the second positioning member 241 can be used to limit the plate 9 to the set longitudinal position. After completing the lateral and longitudinal positioning, the first driving device 26 drives the positioning frame 22 to rise relative to the mounting frame 21. The positioning column 25 on the positioning frame 22 lifts the upper plate 9 located on the positioning frame 22, making it easy for the robot to transfer the plate 9 to the first exposure device 4. After the plate 9 is transferred by the robot, the first driving device 26 resets, driving the positioning frame 22 to reset as well. The above positioning operation is repeated for the next plate 9, and so on, which greatly improves the work efficiency. At the same time, it can also position plates 9 of different sizes, which is convenient for the robot to grasp and place them to the specific exposure area of ​​the exposure device for exposure.

[0041] In this embodiment, the flipping mechanism 5 includes a third drive component 51, a fourth drive component 52, a lifting frame 53, a flipping arm 54, and a first suction unit 55. The third drive component 51 is disposed on one side of the positioning mechanism 2. The fourth drive component 52 is vertically disposed on the third drive component 51, and the third drive component 51 can drive the fourth drive component 52 away from or near the positioning mechanism 2. The lifting frame 53 is disposed on the fourth drive component 52, and the fourth drive component 52 can drive the lifting frame 53 to rise and fall relative to the third drive component 51. The flipping arm 54 is disposed on the lifting frame 53, with one end of the flipping arm 54 movably disposed on the lifting frame 53. The first suction unit 55 is disposed on the other end of the flipping arm 54.

[0042] In this embodiment, the flipping mechanism 5 can pick up and flip the plate 9 exposed by the first exposure device 4, so that the unexposed side of the plate 9 faces outward, making it easier for the robot arm to transfer the plate 9 to the first exposure device 4 for exposure of the unexposed side of the plate 9. Specifically, the third drive component 51 can drive the fourth drive component 52 to move to the identified position according to the specific position of the plate 9 in the exposure area of ​​the first exposure device 4. Then, the fourth drive component 52 drives the lifting frame 53 to descend relative to the third drive component 51, and the flipping arm 54 flips downward to above the exposure area of ​​the first exposure device 4. The first suction unit 55 picks up the plate 9, and then the flipping arm 54 flips upward to reset. Then, the third drive component 51 drives the lifting frame 53 to move upward to reset, so that the fourth suction unit 31 of the robot arm can be aligned with the plate 9 picked up by the first suction unit 55 to complete the flipping. At the same time, the third drive component 51 and the fourth drive component 52 can fine-tune the position of the first suction unit 55 according to the position of the plate 9 of different sizes, so as to align with the fourth suction unit 31 of the robot arm, which improves the practicality of the device.

[0043] In this embodiment, the fully automatic flipping exposure device is further provided with a storage mechanism 8. The storage mechanism 8 is located on one side of the feeding mechanism 7. The first transfer unit 3 can move between the second exposure device 6 and the storage mechanism 8 to move the exposed plate 9 from the second exposure device 6 to the storage mechanism 8. The storage mechanism 8 includes a placement frame 81, a first drive cylinder 82 and a base 83. The placement frame 81 is movably hinged to the base 83. The end of the first drive cylinder 82 is movably hinged to the base 83. The power output end of the first drive cylinder 82 is movably disposed on the placement frame 81 to push the placement frame 81 up or retract it.

[0044] In this embodiment, a storage mechanism 8 is provided to facilitate the temporary storage of the sheet metal 9 exposed by the second exposure device 6 for testing. The qualified sheet metal 9 is transferred to the unloading mechanism 7 for unloading and stacking. The unqualified sheet metal 9 is collected and removed after passing through the storage mechanism 8. Specifically, when an unqualified sheet metal 9 is detected, the first drive cylinder 82 is activated to drive the placement rack 81 to flip downwards, and the unqualified sheet metal 9 on the placement rack 81 is flipped and slid together for collection. Afterwards, the first drive cylinder 82 is reset to drive the placement rack 81 to flip upwards and reset, so as to continue to store the sheet metal 9 transferred by the robot arm. This cycle improves the practicality and working efficiency of the fully automatic flipping exposure device.

[0045] In this embodiment, the feeding mechanism 7 includes a conveying mechanism 71, a second transfer unit 72, a stacking mechanism 73, and a feeding mechanism 74.

[0046] In this embodiment, the second transfer unit 72 includes a movable base 721, a second suction unit 722, a connecting arm 723, and a fifth drive assembly 724. The movable base 721 is slidably disposed on the conveying mechanism 71, the fifth drive assembly 724 is vertically disposed on the movable base 721, one end of the connecting arm 723 is sleeved on the fifth drive assembly 724 and can be raised and lowered relative to the fifth drive assembly 724 in the vertical direction, and the second suction unit 722 is installed on the other end of the connecting arm 723.

The third suction unit 732 is movably disposed on the sixth drive assembly 731 to move the plate 9 from the lifting frame 734 to the unloading mechanism 74.

[0048] In this embodiment, the unloading mechanism 7 adopts the specific mechanism described above. During unloading, the robotic arm first transfers the sheet material 9, which has been exposed by the second exposure device 6, to the placement rack 81 of the storage mechanism 8. After passing inspection, the second suction unit 722 picks up the qualified sheet material 9 and transfers it to the stacking mechanism 73. After passing through the stacking mechanism 73, it is transferred to the unloading mechanism 74 for stacking to complete the unloading. After a certain amount of sheet material 9 is stacked at the unloading mechanism 74, it is transferred to the next work station. Specifically, the conveying mechanism 71 drives the second transfer unit 72 to move it above the storage mechanism 8. At this time, the fifth drive component 724 drives the connecting arm 723 and the second suction unit 722 to move downwards vertically. After the second suction unit 722 picks up the qualified sheet material 9, the fifth drive component drives the connecting arm 723 to move the second suction unit 722 upwards vertically. After resetting, the conveying mechanism 71 drives the second transfer unit 72 back to the stacking mechanism 73. At this time, the fifth drive component 724 drives the connecting arm 723 to move downwards vertically. The third suction unit 722 moves vertically downward together with the second suction unit 722 to the lowering support frame 734 and places the plate 9 on the lowering support frame 734. Then, the sixth drive component 731 drives the third suction unit 732 all the way to the top of the lowering support frame 734. The third suction unit 732 picks up the plate 9 at the lowering support frame 734 and then the sixth drive component 731 drives the third suction unit 732 to move to the unloading mechanism 74 to stack the plate 9. Finally, the fully automatic exposure process of the plate 9 is completed, which greatly improves the exposure efficiency.
