[0002] Screen printing stencil exposure is a crucial step in the screen printing stencil manufacturing process. In this step, photosensitive emulsion is applied to the stencil and then cured by exposure. The purpose of this process is to create a pattern on the stencil using the photosensitive emulsion, facilitating subsequent printing.

[0038] The embodiments of the present invention are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. The embodiments of the present invention are described in detail below.

[0039] The following is for reference. Figures 1-10 The present invention describes a screen printing direct-write lithography machine chuck 100 according to an embodiment of the present invention, and also proposes a direct-write lithography machine 1000 including the above-described screen printing direct-write lithography machine chuck 100.

[0040] like Figures 2-4 As shown, the chuck 100 of the screen printing direct writing lithography machine includes: a chuck body 10, a guide assembly, and a guide rail 30.

[0041] The suction cup body 10 is provided with multiple suction ports 11, which selectively connect to a vacuum device. Specifically, the suction ports 11 open upwards towards the suction cup body 10, and the multiple suction ports 11 are spaced apart along a first direction. The screen plate 400 can selectively abut against the suction ports 11. When the screen plate 400 abuts against the suction port 11, the suction port 11 connects the screen plate 400 and the vacuum device to form a sealed cavity inside the suction cup body 10. When the vacuum device pumps air, a stable negative pressure environment is formed inside the suction cup body 10, thereby stably adsorbing the screen plate 400. When the vacuum device stops pumping air, the negative pressure environment inside the suction cup body 10 is released, releasing the adsorption of the screen plate 400.

[0042] The guiding assembly includes two first guide plates 21 and a second guide plate 22. The two first guide plates 21 extend along a first direction and are arranged opposite each other. The second guide plate 22 extends along a second direction and forms a first receiving space with the two first guide plates 21. Specifically, the first guide plates 21 extend along the first direction, are arranged opposite each other, and are located on both sides of the suction cup body 10, limiting the screen 400. The second guide plate 22 extends along the second direction, forming the first receiving space between the second guide plate 22 and the two first guide plates 21. The screen 400 moves along the first direction between the two first guide plates 21. When the screen 400 moves to contact the second guide plate 22, a vacuum device draws air, creating a stable negative pressure environment within the suction cup body 10, thereby stably adsorbing the screen 400.

[0043] In some embodiments, the four adsorption ports 11 can be respectively located at the four corners of the screen 400 when it comes into contact with the second guide plate 22, so as to ensure that the adsorption force on the screen 400 is uniform.

[0044] At least two guide rails 30 are connected to the suction cup body 10 and spaced apart along the second direction. A first rolling element 31 is disposed above any guide rail 30. The guide rail 30 is selectively connected to an air supply device, and the first rolling element 31 rises or falls. Specifically, an air float port is provided on the guide rail 30, and the first rolling element 31 is disposed in the air float port. The first rolling element 31 can move up and down within the air float port. The air float port can be connected to the air supply device. When the air supply device is connected to the air float port, the first rolling element 31 rises; when the air supply device is disconnected from the air float port, the first rolling element 31 falls. The first rolling element 31 can be a universal ball bearing, so that the screen 400 can move along the first direction on the first rolling element 31. When it moves to abut against the second guide plate 22, it reaches the exposure position and exposes the screen 400.

[0045] Before the operator loads the material, the air supply device is connected to the guide rail 30, and the first rolling element 31 rises so that its upper surface is higher than the suction port 11. The operator places the screen 400 on the first rolling element 31, and the screen 400 comes into contact with the first rolling element 31. Then, the operator pushes the screen 400 along the first direction. When the screen 400 comes into contact with the second guide plate 22, the first rolling element 31 descends, and the vacuum device evacuates the air, creating a stable negative pressure environment within the suction cup body 10, thus stably adsorbing the screen 400. After the screen 400 has been exposed, the vacuum device stops evacuating the air, releasing the negative pressure environment inside the suction cup body 10 and releasing the adsorption of the screen 400. The operator can then move the screen 400 along the first direction to unload it. The next screen 400 is placed, and the above steps are repeated.

[0046] Thus, when the first rolling element 31 rises, the screen 400 can be fed and unloaded along the first direction; when the first rolling element 31 falls, the suction port 11 can vacuum-adsorb the screen 400; the first guide plate 21 and the second guide plate 22 ensure the positioning accuracy of the screen 400 feeding.

[0047] like Figure 5 As shown, a second rolling element 211 is provided on the first guide plate 21, and a third rolling element 221 is provided on the second guide plate 22. When the screen 400 moves along the first direction, it rolls in cooperation with the second rolling element 211. When the screen 400 is connected to the vacuum device, it abuts against the third rolling element 221. Specifically, the second rolling element 211 is located on the side of the first guide plate 21 facing the other first guide plate 21. When the screen 400 moves along the first direction between the two first guide plates 21, the screen 400 abuts against the second rolling element 211. The second rolling element 211 can be a universal ball bearing. The second rolling element 211 and the screen 400 experience rolling friction to avoid damage to the screen 400.

[0048] In some embodiments, the chuck 100 of the screen printing direct-write lithography machine further includes a solenoid valve. The solenoid valve is used to connect or disconnect the guide rail 30 and the gas supply device to cause the first rolling element 31 to rise or fall. Specifically, the solenoid valve controls the connection and disconnection between the guide rail 30 and the gas supply device. When the solenoid valve connects the guide rail 30 and the gas supply device, the vacuum device and the chuck body 10 are disconnected. When the solenoid valve disconnects the guide rail 30 and the gas supply device, the vacuum device and the chuck body 10 are connected. When the screen 400 abuts against the suction port 11, the chuck body 10 adsorbs the screen 400, thereby performing operations such as exposure on the screen 400.

[0049] Before the operator loads the material, the solenoid valve connects the guide rail 30 and the air supply device, causing the first rolling element 31 to rise. The operator pushes the screen 400 to move along the first direction. When the screen 400 moves to contact the second guide plate 22, the solenoid valve disconnects the guide rail 30 and the air supply device, causing the first rolling element 31 to fall. The vacuum device connects to the suction port 11 and evacuates air, creating a stable negative pressure environment inside the suction cup body 10, thereby stably adsorbing the screen 400. After the screen 400 has been exposed, the vacuum device stops evacuating air, releasing the negative pressure environment inside the suction cup body 10. The solenoid valve connects the guide rail 30 and the air supply device, releasing the adsorption of the screen 400, allowing the operator to move the screen 400 along the first direction for unloading.

[0050] In some embodiments, a trigger button is provided on the suction cup body 10, and the trigger button is electrically connected to the solenoid valve. When the screen 400 is being fed, pressing the trigger button connects the solenoid valve to the guide rail 30 and the air supply device, causing the first rolling element 31 to rise, and the screen 400 can be fed in the first direction; after exposure is completed, pressing the trigger button disconnects the vacuum device and the suction port 11, and the solenoid valve connects the guide rail 30 and the air supply device, causing the first rolling element 31 to rise, and the screen 400 can be fed in the first direction.

[0051] Combination Figure 5 , Figure 8 and Figure 9 As shown, the chuck 100 of the screen printing direct-write lithography machine also includes: an optical fiber sensor. The chuck body 10 is provided with a through hole 14 extending along the height direction. The optical fiber sensor is disposed in the through hole 14 and is electrically connected to a solenoid valve. When the screen 400 moves to abut against the second guide plate 22, the optical fiber sensor is triggered, and the solenoid valve disconnects the guide rail 30 and the gas supply device. Specifically, the through hole 14 is located near the second guide plate 22, on the side of the second guide plate 22 facing the screen 400. The optical fiber sensor is located in the through hole 14. When the screen 400 moves along the first direction to abut against the second guide plate 22, the screen 400 covers the optical fiber sensor. The optical fiber sensor detects the signal and controls the solenoid valve to disconnect the guide rail 30 and the gas supply device, causing the first rolling element 31 to descend. The screen 400 abuts against the adsorption port 11. The vacuum device is connected to the adsorption port 11, thus forming a stable negative pressure environment in the chuck body 10, thereby stably adsorbing the screen 400.

[0052] like Figure 5As shown, the upper part of the suction cup body 10 is provided with multiple adsorption elements 13. The multiple adsorption elements 13 are respectively disposed at multiple adsorption ports 11 and are connected to the screen plate 400 and the vacuum device. Specifically, the multiple adsorption elements 13 are respectively disposed at multiple adsorption ports 11 and are connected to the periphery of the adsorption ports 11. When the screen plate 400 moves along the first direction to abut against the second guide plate 22, the first rolling element 31 descends, and the screen plate 400 abuts against the adsorption elements 13. At this time, the adsorption elements 13 are connected to the vacuum device, forming a stable negative pressure environment inside the suction cup body 10 to stably adsorb the screen plate 400.

[0053] The adsorption element 13 can be made of rubber and is generally funnel-shaped to stabilize the adsorption screen 400.

[0054] In some embodiments, a groove is provided on the periphery of the suction port 11. When the screen plate 400 abuts against the suction member 13, the suction member 13 can be pressed into the groove so that the screen plate 400 abuts against the upper surface of the suction cup body 10, ensuring that the suction cup body 10 tightly adsorbs the screen plate 400 without affecting the flatness of the screen plate 400.

[0055] In some embodiments, the suction cup body 10 is provided with multiple airflow channels, which are respectively connected to multiple adsorption ports 11 and a vacuum device. Specifically, the multiple airflow channels are separated from each other within the suction cup body 10, and are respectively connected to multiple adsorption ports 11. One end of each airflow channel is connected to the adsorption port 11, and the other end is connected to the vacuum device, so that a negative pressure environment is formed in the airflow channels when the vacuum device evacuates air, thereby allowing the adsorption port 11 to adsorb the screen plate 400.

[0056] In some embodiments, the side of the suction cup body 10 is also provided with an air extraction port 12, which is connected to a vacuum device and to the other end of an airflow channel. There can be multiple air extraction ports 12, each connected to the other end of a multiple airflow channel, and multiple suction ports 11 connected to one end of a multiple airflow channel. When the screen 400 comes into contact with the suction port 11, the vacuum device extracts air, creating a negative pressure environment in the airflow channel, thereby allowing the suction port 11 to adsorb the screen 400.

[0057] Combination Figures 2-3 , Figures 6-7As shown, the guiding assembly further includes a third guide plate 23, which is disposed between two first guide plates 21. The third guide plate 23 extends along a first direction and is movable up and down, selectively forming a second receiving space with the first guide plates 21 and the second guide plate 22. Specifically, the third guide plate 23 is located between two first guide plates 21 and also extends along the first direction. The third guide plate 23 is movable up and down relative to the suction cup body 10. When the third guide plate 23 moves down, the two first guide plates 21 and the second guide plate 22 form a first receiving space; when the third guide plate 23 moves up, the third guide plate 23 forms a second receiving space with one of the first guide plates 21 and the second guide plate 22. The size of the second receiving space in the second direction is smaller than the size of the first receiving space, that is, Figure 3 The screen size in the middle is 400. Figure 2 The screen 400 is of a certain size. The first and second accommodating spaces can be used to accommodate screens 400 of different sizes, expanding the applicability of the chuck 100 of the screen direct-write lithography machine.

[0058] At least one guide rail 30 is disposed adjacent to the third guide plate 23, and this guide rail 30 is disposed parallel to the guide rail 30 corresponding to one of the first guide plates 21, so that the screen 400 of the second accommodating space size slides on the two guide rails 30 along the first direction. The loading and unloading steps of the screen 400 are the same as those of the screen 400 of the first accommodating space size. The four suction ports 11 are respectively disposed at the four corners where the screen 400 abuts against the third guide plate 23.

[0059] like Figure 3 and Figure 9 As shown, the chuck 100 of the screen printing direct-write lithography machine also includes a lifting assembly 50, which is located below the chuck body 10. The lifting assembly 50 is connected to the third guide plate 23 and drives the third guide plate 23 to move up and down. That is, the lifting assembly 50 drives the third guide plate 23 to move up and down. The third guide plate 23 is provided with a fourth rolling element 231, which can be a universal ball bearing. A second receiving space is formed between the third guide plate 23 and one of the first guide plates 21 and the second guide plate 22. The screen 400 adapted to the second receiving space moves along the first direction between one of the first guide plates 21 and the third guide plate 23. The screen 400 abuts against the first rolling element 31 and the fourth rolling element 231 on both sides in the second direction. The third guide plate 23 and one of the first guide plates 21 limit the screen 400, thus limiting the screen 400 and preventing damage to the screen 400.

[0060] If a screen 400 that is compatible with the first receiving space is required, the lifting component 50 drives the third guide plate 23 to move downward so that the upper surface of the third guide plate 23 is lower than the upper surface of the suction cup body 10; if a screen 400 that is compatible with the second receiving space is required, the lifting component 50 drives the third guide plate 23 to move upward so that the fourth rolling element 231 on the third guide plate 23 is at the same height as the first rolling element 31.

[0061] Furthermore, the lifting assembly 50 includes a driving component and a transmission component. The transmission component is connected to the third guide plate 23. The driving component drives the transmission component to move up and down, thereby causing the third guide plate 23 to move up and down. Specifically, the driving component can be a cylinder. The driving component drives the transmission component to move up and down. The transmission component is connected to the third guide plate 23, and the third guide plate 23 moves as the transmission component moves up and down. If a screen 400 that fits the first accommodating space needs to be fed, the driving component drives the transmission component to move downward, so that the third guide plate 23 moves downward, making the upper surface of the third guide plate 23 lower than the upper surface of the suction cup body 10; if a screen 400 that fits the second accommodating space needs to be fed, the driving component drives the transmission component to move upward, so that the third guide plate 23 moves upward, so that the fourth rolling element 231 on the third guide plate 23 is at the same height as the first rolling element 31, so that the screen 400 can move along the first direction with the cooperation of the first rolling element 31 and the fourth rolling element 231. The first rolling element 31 and the fourth rolling element 231 have rolling friction with the screen 400, reducing damage to the screen 400.

[0062] like Figure 1 As shown, the direct-write lithography machine 1000 includes: a screen printing lithography chuck 100, a motion platform 200, and an exposure optical path module 300. The screen printing lithography chuck 100 is located on the motion platform 200, which is connected to the chuck body 10. The exposure optical path module 300 is located above the screen printing lithography chuck 100 and is used to expose the screen 400. The screen 400 is fixed by vacuum adsorption, which is compatible with various specifications of screen 400, greatly improving the versatility and adaptability of the direct-write lithography machine 1000. In addition, the screen printing lithography chuck 100 is also equipped with a guide component, which allows for manual assistance in loading and unloading, further improving the convenience of operation.
