Description

Technical Field

[0001] The present invention relates to the technical field of automatic exposure, and particularly to a double-sided exposure device. Background Art

[0002] In recent years, with the rapid development of electronic technology, the demand for improving production capacity in the PCB industry has increased sharply. The production capacity of traditional fully automatic exposure machines in the solder mask exposure process can only reach 3 - 3.5 sheets per minute, and usually adopts a single-sided exposure and single-frame operation design; in the past two years, some enterprises have changed the traditional design method and adopted a single-sided exposure and double-frame operation design, with a production capacity of up to 5 - 6 sheets per minute. Even so, for the growing demand, it still cannot meet the requirements of the current printed circuit board manufacturing industry.

[0003] Based on the need to expose both sides of the PCB board respectively, after one side of the board is exposed, a flipping mechanism is required to flip the board to expose the other side. The overall size of existing automated exposure equipment is too large, occupying a large area, the CT of the connection operation is too long, and the overall production capacity is low. The exchange board process is complex and two devices are required to expose the two sides A and B of the product. Moreover, traditional double-sided exposure machines generally target fixed board models or sizes, or need to stop the machine manually to change the distance and replace the corresponding picking or clamping mechanism for several different sizes, which undoubtedly results in poor versatility and low efficiency of the equipment.

After the board passes through the feeding mechanism and is calibrated and positioned by the positioning mechanism, the manipulator of the first transfer unit transfers the board to the first exposure device for exposure. After the exposure is completed, the turning-over mechanism sucks up and flips the board so that the unexposed side of the board faces outward. At the same time, the manipulator adsorbs the unexposed side of the board and transfers it to the second exposure device for exposure. After the board completes double-sided exposure, the manipulator is used to transfer the board to the discharging mechanism for discharging and stacking; a turning-over mechanism is arranged in the first exposure device and the second exposure device, so that the double-sided exposure device can realize double-sided exposure; at the same time, in this solution, due to the arrangement of the first exposure device and the second exposure device, the waiting time for the board to be placed is short, which greatly improves the production capacity of the double-sided exposure device.

Detailed implementation manners

[0031] For the convenience of those skilled in the art to understand, the following combines embodiments and attached Figures 1-11 to further illustrate the present invention. The content mentioned in the implementation manners does not limit the present invention.

[0032] See Figures 1-11 , the object of the present invention is achieved through the following technical solutions: A double-sided exposure device, including a loading mechanism 1, the loading mechanism 1 is used for conveying a sheet material 9, and a positioning mechanism 2 is arranged at the discharging end of the loading mechanism 1;

[0034] A turning mechanism 5, the turning mechanism 5 is used to obtain the sheet material 9 from the first exposure device 4 so that the unexposed side of the sheet material 9 faces outward;

[0035] The first transfer unit 3 can move between the positioning mechanism 2 and the first exposure device 4 to move the sheet 9 from the positioning mechanism 2 to the first exposure device 4; the first transfer unit 3 can move between the turning mechanism 5 and the second exposure device 6 to expose the unexposed side of the sheet 9 from the turning mechanism 5 to the second exposure device 6; the first transfer unit 3 can move between the second exposure device 6 and the blanking mechanism 7 to move the sheet 9 from the second exposure device 6 to the blanking mechanism 7 for blanking; the first transfer unit 3 is a manipulator, and the manipulator is provided with a fourth suction unit 31.

[0036] The surface exposure device in this embodiment is provided with a loading mechanism 1, a positioning mechanism 2, a first exposure device 4, a second exposure device 6, a turning mechanism 5 and a blanking mechanism 7, and is provided with a first transfer unit 3 that can switch between the positioning mechanism 2, the first exposure device 4, the second exposure device 6, the turning mechanism 5 and the blanking mechanism 7; when performing the exposure process, first, the sheet 9 is conveyed to the positioning mechanism 2 by the loading mechanism 1 for calibration and positioning, and then the manipulator is used to transfer the sheet 9 to the first exposure device 4 for exposure. After the exposure is completed, the turning mechanism 5 is activated to suck and turn the sheet 9 so that the unexposed side of the sheet 9 faces outward. At the same time, the manipulator adsorbs the unexposed side of the sheet 9 and transfers it to the second exposure device 6 for exposure of the sheet 9. After the sheet 9 is double-sided exposed, the manipulator is used to transfer the sheet 9 to the blanking mechanism 7 for blanking and stacking; the turning mechanism 5 is provided in the first exposure device 4 and the second exposure device 6, so that the double-sided exposure device can realize double-sided exposure; at the same time, in this solution, since two exposure devices are provided, the waiting time for the sheet 9 to be placed is short, and a new sheet 9 is sucked from the loading device again; during the process of the first exposure device 4 exposing the first side of the sheet 9, the loading mechanism 1 conveys the second sheet 9 to the positioning mechanism 2 for calibration and positioning. After the previous sheet 9 is sucked and turned by the turning mechanism 5, the manipulator transfers it to the second exposure device 6 for exposure. The manipulator returns to its position and then transfers the second sheet 9 to the first exposure device 4 for exposure. The manipulator returns to its position and then transfers the first sheet 9 that has been double-sided exposed from the second exposure device 6 to the blanking mechanism 7. At the same time, the second sheet 9 is sucked and turned by the turning mechanism 5, and then the manipulator transfers it to the second exposure device 6 for exposure, and so on. After the double-sided exposure process of the sheet 9 corresponding to the second exposure device 6 is completed, the sheet 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 double-sided exposure device.

[0037] In this embodiment, the positioning mechanism 2 includes a mounting frame 21, a positioning frame 22, a lateral positioning mechanism 23, and a longitudinal positioning mechanism 24. A plurality of uniformly distributed positioning posts 25 are provided on the positioning frame 22. The positioning frame 22 is movably arranged 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 move up and down relative to the mounting frame 21. The lateral positioning mechanism 23 is provided with a movable first positioning member 231. The lateral positioning mechanism 23 is located on one side of the positioning frame 22. The longitudinal positioning mechanism 24 is provided with a movable second positioning member 241.

[0038] In this embodiment, the lateral positioning mechanism 23 includes a first positioning member 231, a first base 232, and a first driving assembly 233. The first driving assembly 233 is arranged on the first base 232. The first positioning member 231 is connected to the first driving assembly 233, and the first driving assembly 233 can drive the first positioning member 231 to move away from or close to the mounting frame 21.

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

[0040] In this embodiment, the positioning mechanism 2 adopts the above specific structure. During positioning, the feeding mechanism 1 conveys the plate 9 to the positioning frame 22. The lateral positioning mechanism 23 can limit the plate 9 to a laterally set position at the discharging end of the feeding mechanism 1. At the same time, in combination with the longitudinal positioning mechanism 24, the plate 9 can be limited to a longitudinally set position at the discharging end of the feeding mechanism 1. Specifically, when the lateral positioning mechanism 23 positions, first, the first driving assembly 233 drives the first positioning member 231 to move laterally in the feeding direction of the plate 9 to a set position, and then the first positioning member 231 can limit the plate 9 to the set lateral position. Then, the transverse and longitudinal positioning mechanism 24 positions. First, the second driving assembly 243 drives the second positioning member 241 to move in a direction perpendicular to the feeding direction of the plate 9 to a set position, and then the second positioning member 241 can 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, and the positioning column 25 on the positioning frame 22 jacks up the plate 9 located on the positioning frame 22 to facilitate the manipulator to transfer the plate 9 to the first exposure device 4. After the plate 9 is transferred by the manipulator, the first driving device 26 resets and drives the positioning frame 22 to reset together, and then repeats the above positioning operation for the next plate 9, and so on, continuously cycling, which greatly improves the working efficiency. At the same time, it can also position plates 9 of different sizes, which is conducive to the manipulator to grab and place them in a specific exposure area of the exposure device for exposure.

[0041] In this embodiment, the turning-over mechanism 5 includes a third driving assembly 51, a fourth driving assembly 52, a lifting frame 53, a turning-over arm 54, and a first suction unit 55. The third driving assembly 51 is arranged on one side of the positioning mechanism 2. The fourth driving assembly 52 is vertically arranged on the third driving assembly 51, and the third driving assembly 51 can drive the fourth driving assembly 52 to move away from or close to the positioning mechanism 2. The lifting frame 53 is arranged on the fourth driving assembly 52, and the fourth driving assembly 52 can drive the lifting frame 53 to lift relative to the third driving assembly 51. The turning-over arm 54 is arranged on the lifting frame 53. One end of the turning-over arm 54 is movably arranged on the lifting frame 53, and the first suction unit 55 is arranged at the other end of the turning-over arm 54.

[0042] In this embodiment, the turning mechanism 5 can lift and turn the plate 9 after being exposed by the first exposure device 4, so that the unexposed side of the plate 9 faces outward, facilitating the manipulator to transfer the plate 9 to the first exposure device 4 to expose the unexposed side of the plate 9. Specifically, the third driving component 51 can drive the fourth driving 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. After the fourth driving component 52 drives the lifting frame 53 to descend relative to the third driving component 51, the turning arm 54 turns downward to above the exposure area of the first exposure device 4, sucks the plate 9 by the first suction unit 55, and then the turning arm 54 turns upward to reset. Then, the third driving component 51 drives the lifting frame 53 to move upward to reset, facilitating the fourth suction unit 31 of the manipulator to align with the plate 9 sucked by the first suction unit 55 to complete the turning. At the same time, the third driving component 51 and the fourth driving component 52 can fine-tune the position of the first suction unit 55 according to the position of different-sized plates 9 to facilitate alignment with the fourth suction unit 31 of the manipulator, improving the practicability of this device.

[0043] In this embodiment, the double-sided exposure device is further provided with a storage mechanism 8. The storage mechanism 8 is located on one side of the blanking 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 rack 81, a first driving cylinder 82, and a seat frame 83. The placement rack 81 is movably hinged to the seat frame 83. The end of the first driving cylinder 82 is movably hinged to the seat frame 83, and the power output end of the first driving cylinder 82 is movably arranged on the placement rack 81 to push up or retract the placement rack 81.

[0044] In this embodiment, by setting the storage mechanism 8, it is convenient to temporarily store the plate 9 that has been exposed by the second exposure device 6 at the storage mechanism 8 for inspection. The qualified plates 9 will be transferred to the blanking mechanism 7 for blanking and stacking. The unqualified plates 9 will be collected and taken away after passing through the storage mechanism 8. Specifically, when an unqualified plate 9 is detected, the first driving cylinder 82 is activated to drive the placement rack 81 to turn downward, turning and sliding the unqualified plates 9 on the placement rack 81 together for collection. Then, the first driving cylinder 82 resets to drive the placement rack 81 to turn upward to reset, facilitating the continuous storage of the plates 9 transferred by the manipulator. In this way, the practicability and working effect of the double-sided exposure device are improved.

[0045] In this embodiment, the blanking mechanism 7 includes a conveying mechanism 71, a second transfer unit 72, a stacking mechanism 73 and a blanking mechanism 74. The conveying mechanism 71 is arranged on one side of the second exposure device 6. The storage mechanism 8 is located on one side of the conveying mechanism 71. The second transfer unit 72 is arranged on the conveying mechanism 71 and can move on the conveying mechanism 71.

[0046] In this embodiment, the second transfer unit 72 includes a moving base 721, a second suction unit 722, a connecting arm 723 and a fifth driving component 724. The moving base 721 is slidably arranged on the conveying mechanism 71. The fifth driving component 724 is vertically arranged on the moving base 721. One end of the connecting arm 723 is sleeved on the fifth driving component 724 and can move up and down relative to the fifth driving component 724 in the vertical direction.

The third suction unit 732 is movably arranged on the sixth driving component 731 to move the board 9 from the lowering support frame 734 to the blanking mechanism 74.

[0048] In this embodiment, the blanking mechanism 7 adopts the above specific mechanism. During blanking, first, the manipulator transfers the sheet 9 that has been exposed by the second exposure device 6 to the placement rack 81 of the storage mechanism 8. After passing the inspection, the second suction unit 722 sucks the qualified sheet 9 and transfers it to the stacking mechanism 73. Then, after passing through the stacking mechanism 73, it is transferred to the discharging mechanism 74 for stacking to complete the blanking. When a certain amount of sheets 9 are stacked at the discharging mechanism 74, they are transferred to the next working station. Specifically, the conveying mechanism 71 drives the second transfer unit 72 and moves it above the storage mechanism 8. At this time, the fifth driving component 724 drives the connecting arm 723 and the second suction unit 722 to move downward together in the vertical direction until the second suction unit 722 sucks the qualified sheet 9. After that, the five driving components drive the connecting arm 723 to drive the second suction unit 722 to move upward together in the vertical direction to reset. Then, the conveying mechanism 71 drives the second transfer unit 72 to return to the stacking mechanism 73. At this time, the fifth driving component 724 drives the connecting arm 723 and the second suction unit 722 to move downward together in the vertical direction to the lowering support frame 734 and place the sheet 9 on the lowering support frame 734. Then, the sixth driving component 731 drives the third suction unit 732 until it is above the lowering support frame 734. The third suction unit 732 sucks the sheet 9 at the lowering support frame 734 and then the sixth driving component 731 drives the third suction unit 732 to move to the discharging mechanism 74 to stack the sheets 9. Finally, the fully automatic exposure process of the sheet 9 is completed, greatly improving the exposure efficiency.
