Abstract
Description
Technical Field
[0001] This utility model relates to the field of exposure machines, and in particular to an exposure machine and a feeding mechanism. Background Technology
[0002] An exposure machine is a device that uses UVA wavelength ultraviolet light emitted by turning on a light to transfer image information from film or other transparent materials to a surface coated with a photosensitive substance.
[0003] For example, the utility model patent with announcement number CN222299948U discloses a double-sided automatic exposure machine for wafer production. It mentions that by driving the carrier and the wafer in the storage tank to rotate around the rotating shaft, the wafer is rotated. Combined with the exposure of the exposure device, the wafer can be exposed on both sides. However, when the exposure machine is exposing the object, a cooling device is usually required to cool the object. In order not to obstruct the exposure machine, the cooling device is usually located below the object. However, the above-mentioned patent directly drives the object to rotate through a motor, which would cause the cooling device to obstruct the machine. Utility Model Content
[0004] Therefore, the purpose of this utility model is to provide an exposure machine and a feeding mechanism.
[0005] This utility model provides the following technical solution: a feeding mechanism, including a slide rail, a slider slidably connected on the slide rail, a driving component for driving the slider to move, a rotating shaft rotatably connected on the slider, a driving assembly for driving the rotating shaft to rotate on the slider, a feeding tray on the rotating shaft, and a plurality of fixing components on the feeding tray; wherein, the feeding tray has a hollow structure in the middle, and the feeding tray is recessed inward to form a stepped surface, a PCB board is placed on the stepped surface, and the fixing components are used to fix the PCB board on the feeding tray; the driving assembly drives the rotating shaft to rotate, thereby changing the face of the PCB board on the feeding tray.
[0006] Furthermore, the drive assembly includes a motor mounted on the slider, a worm gear mounted on the output shaft of the motor, and a turbine mounted on the rotating shaft, the turbine meshing with the worm gear.
[0007] Furthermore, the fixing component includes a sliding sleeve disposed on the material tray, a sliding rod slidably connected to the sliding sleeve, a clamping piece disposed on the sliding rod, and a spring disposed between the sliding rod and the sliding sleeve, wherein the clamping piece presses against the edge of the PCB board.
[0008] Furthermore, two fixing components are provided and are symmetrically distributed on both sides of the material tray, and a connecting plate is connected between the slide rods of the two fixing components.
[0009] An exposure machine includes a support, an exposure machine body disposed on the support, the aforementioned feeding mechanism disposed on the support, and a cooling module for cooling the PCB board.
[0010] Furthermore, the cooling module includes a storage tank mounted on the bracket, a pump body mounted on the storage tank, a cooling tank mounted on the bracket, an output pipe connected between the cooling tank and the pump body, and a recovery pipe connected between the cooling tank and the storage tank; the cooling tank is located directly below the PCB board.
[0011] The beneficial effects of this utility model are as follows: By activating the drive unit, the drive unit moves the slider upward, causing the material tray to move away from the cooling module. Once it reaches the appropriate position, the operator can activate the motor, which will drive the worm gear to rotate, the worm gear to rotate the turbine, the turbine to rotate the rotating shaft, and the rotating shaft to rotate the material tray, thereby rotating the material tray 180 degrees for face changing. Then, the operator activates the drive unit, causing the drive unit to move the slider downward, thereby moving the material tray downward. The downward movement of the material tray brings the PCB board closer to the cooling module, allowing the cooling module to cool the PCB board, thus effectively preventing the cooling module from obstructing the PCB board face changing.

[0021] For reference Figures 2-4 This utility model provides a first embodiment, which provides a feeding mechanism 4, including a slide rail 41, a slider 42 slidably connected to the slide rail 41, a driving member 44 for driving the slider 42 to move, a rotating shaft 45 rotatably connected to the slider 42, a driving component 43 disposed on the slider 42 for driving the rotating shaft 45 to rotate, a feeding tray 46 disposed on the rotating shaft 45, and a plurality of fixing components 47 disposed on the feeding tray 46; wherein, the driving component 43 drives the rotating shaft 45 to rotate, thereby changing the surface of the PCB board 48 on the feeding tray 46.
[0022] The system includes a vertical slide rail 41 with a vertically oriented groove. A slider 42 is slidably connected to the slide rail 41 via the groove. The driving component 44 is preferably an electric push rod, but in other embodiments, it can be a combination of a motor and a screw. The screw is threadedly connected to the slider 42 and fixedly connected to the output shaft of the motor. The motor drives the screw to rotate, thereby moving the slider 42 up and down. A rotating shaft 45 is rotatably connected to the side of the slider 42 away from the slide rail 41. The driving assembly 43 specifically includes a motor 431 mounted on the slider 42, a worm gear 432 mounted on the output shaft of the motor 431, and a turbine 433 mounted on the rotating shaft 45. The turbine 433 meshes with the worm gear 432. Starting the motor 431 drives the worm gear 432 to rotate, and the worm gear 432 drives the rotating shaft 45 to rotate via the turbine 433, thereby causing the PCB board 48 to change sides. The material tray 46 is arc-shaped with a hollow center. The material tray 46 is recessed inward to form a stepped surface 461, and the PCB board 48 is placed on the stepped surface 461. Two sets of fixing components 47 are provided on the material tray 46 and are symmetrically distributed on both sides of the material tray 46. The two sets of fixing components 47 are used to fix the PCB board 48 on the material tray 46. In other embodiments, the number of fixing components 47 can be adjusted according to the actual situation. The fixing components 47 specifically include: a sliding sleeve 471 provided on the material tray 46, a sliding rod 472 slidably connected on the sliding sleeve 471, a clamping piece 473 provided on the sliding rod 472, and a spring 474 provided between the sliding rod 472 and the sliding sleeve 471. The clamping piece 473 presses the edge of the PCB board 48. Furthermore, a connecting plate 475 is connected between the sliding rods 472 of the two fixing components 47. By pulling the connecting plate 475, the two sliding rods 472 are moved, so that the two clamping pieces 473 no longer press the PCB board 48.
[0023] In summary, when the operator needs to expose the PCB board 48, firstly, by pushing the connecting plate 475 upwards, the operator moves the sliding rod 472 upwards, which in turn moves the clamping plate 473 upwards, compressing the spring 474. Then, the operator places the PCB board 48 to be exposed onto the stepped surface 461 of the material tray 46, and then releases the connecting plate 475. At this point, the spring 474 returns to its original position, which in turn moves the sliding rod... 472 moves downwards, thereby causing the clamping piece 473 to move downwards and press against the PCB board 48, fixing the PCB board 48 onto the placement tray 46. Further, the clamping pieces 473 of the two sets of fixing components 47 secure both sides of the PCB board 48, ensuring a firm fixation on the placement tray 46. After the PCB board 48 is secured, the operator can start the exposure machine body 2 to expose the upper surface of the PCB board 48. After exposure, the operator can start the drive unit 44, which... The sliding block 42 moves upward, moving the material tray 46 away from the cooling module 3. Once it reaches the desired position, the operator can start the motor 431. The motor 431 will drive the worm gear 432 to rotate, which in turn drives the turbine 433 to rotate. The turbine 433 will then drive the rotating shaft 45 to rotate, which in turn drives the material tray 46 to rotate. This causes the material tray 46 to rotate 180 degrees for face changing. At this point, the upper face of the PCB board 48 is now on top of the lower face, with the lower face on top of the upper face. The operator then starts the drive unit 44 to drive the material tray 46 to rotate. The moving part 44 drives the slider 42 to move downward, thereby moving the material tray 46 downward. The downward movement of the material tray 46 moves the PCB board 48 closer to the cooling module 3, so that the cooling module 3 can cool the PCB board 48. Then, the exposure machine body 2 is restarted to expose the PCB board 48, thus completing the exposure work on both ends of the PCB board 48. After the exposure work is completed, the connecting plate 475 is pushed so that the clamping plate 473 no longer presses against the PCB board 48, and then the PCB board 48 can be taken out.
[0024] This utility model provides a second embodiment, which can be referred to. Figure 1 and Figure 5 The second embodiment provides an exposure machine, including a support 1, an exposure machine body 2 disposed on the support 1, the feeding mechanism 4 of the first embodiment disposed on the support 1, and a cooling module 3 for cooling the PCB board 48.
[0025] The cooling module 3 includes a storage tank 31 mounted on the support 1, a pump body 32 mounted on the storage tank 31, a cooling tank 34 mounted on the support 1, an output pipe 33 connecting the cooling tank 34 and the pump body 32, and a recovery pipe 35 connecting the cooling tank 34 and the storage tank 31; the cooling tank 34 is located directly below the PCB board 48.
[0026] It is understood that the exposure machine body 2 is used to expose the PCB board 48, and the cooling module 3 is used to cool the PCB board 48 during processing. The feeding mechanism 4 can be referred to the specific description in Embodiment 1. The cooling module 3 is also existing technology. Not only the cooling module 3 mentioned in this embodiment can be used, but also the cooling module 3 in the prior art. The cooling module 3 in this embodiment is: the storage tank 31 can store cooling liquid, and the storage tank 31 is equipped with cooling plates to cool the liquid in the storage tank 31. The cooling liquid is introduced into the cooling tank 34 through the pump body 32. Since the PCB board 48 is close to the cooling tank 34 during processing, the cooling tank 34 containing cooling liquid can cool the PCB board 48. The recovery pipe 35 is used to return the cooling liquid in the cooling tank 34 back to the storage tank 31. The cooling module 3 in this embodiment is a common circulating cooling, which will not be described in detail again.
[0027] In summary, by activating the drive unit 44, the slide block 42 moves upward, moving the material tray 46 away from the cooling module 3. Once it reaches the appropriate position, the operator can activate the motor 431. The motor 431 will drive the worm gear 432 to rotate, which in turn drives the turbine 433 to rotate. The turbine 433 will then drive the rotating shaft 45 to rotate, which in turn drives the material tray 46 to rotate, thus rotating the material tray 46 180 degrees for face changing. Next, the operator activates the drive unit 44, which moves the slide block 42 downward, causing the material tray 46 to move downward. This downward movement of the material tray 46 brings the PCB board 48 closer to the cooling module 3, allowing the cooling module 3 to cool the PCB board 48. This effectively prevents the cooling module 3 from obstructing the PCB board 48 during face changing.
