Description

Technical Field

[0001] The utility model belongs to the technical field of laser direct writing exposure machines, and in particular relates to a withdrawable upward-lifting table frame mechanism of a laser direct writing photolithography machine. Background Art

[0002] The stage frame of the laser direct writing exposure machine plays a vital role in the entire exposure process. Specifically, the stage frame is mainly used to support, position and stabilize the material to be exposed to ensure the accuracy and stability of the exposure process. It provides a stable platform for the material to be exposed, allowing the laser beam to accurately etch the template or photographic film, thereby achieving a high-precision exposure effect.

[0003] Currently, the table frame is a key component for supporting and positioning the material to be exposed, and the cleanliness of its surface directly affects the accuracy of the exposure process. If dust, oil or other impurities accumulate on the table frame, it may cause scattering or deviation of the laser beam, thereby reducing the exposure accuracy and affecting the quality of the final product. Therefore, the workbench frame needs to be cleaned regularly. However, when cleaning the workbench frame, since the workbench frame and the frame of the laser direct writing exposure machine are connected by sliding, after the top of the workbench frame is cleaned, when it is necessary to clean the bottom of the workbench frame, the cleaning staff needs to bend over or squat to clean the workbench frame, which makes cleaning inconvenient.

[0012] Preferably, a handle is provided on the surface of the workbench frame.

[0013] Compared with the prior art, the beneficial effect of the utility model is that when the workbench frame needs to be cleaned, the workbench frame is pulled out of the bearing guide rail in the platform frame by the handle, so that the workbench frame is slidably pulled out of the platform frame, and the second threaded shaft pin is screwed to rotate in the second threaded cylinder, so that the second threaded shaft pin continues to move toward the workbench frame and contacts the workbench frame, and under continuous screwing, the second threaded shaft pin is tightly pressed against the workbench frame, thereby increasing the resistance of the workbench frame to slide, so that the workbench frame cannot slide in the load-bearing bearing. At this time, the workbench frame can be lifted up, so that the workbench frame can rotate on the surface of the fixed plate through the rotating plates on both sides. After the workbench frame is flipped to a suitable cleaning angle, the first threaded shaft pin in the first threaded cylinder is screwed, so that the first threaded shaft pin is tightly pressed against the workbench frame under continuous screwing, so that the first threaded shaft pin increases the resistance to the flipping of the workbench frame, and the workbench frame cannot be flipped, thereby making it convenient for cleaning personnel to clean the top and bottom of the flipped workbench frame, which is more convenient.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] The utility model provides Figure 1-4 The removable flip-up table frame mechanism of the laser direct writing lithography machine shown in the figure comprises:

[0021] A table frame 1, wherein connecting plates 2 are provided on both sides of the front end of the table frame 1, and a fixing plate 4 is rotatably connected to the surface of the connecting plate 2 via a rotating shaft 3;

[0022] A workbench frame 5 is slidably connected to the bottom of the table frame 1. The surface of the fixed plate 4 is rotatably connected to a rotating plate 6. The surface of the rotating plate 6 is rotatably connected to a plurality of load-bearing bearings 7. Both sides of the workbench frame 5 are rollingly connected to the load-bearing bearings 7. A bearing guide rail 10 is provided in the slide groove at the bottom of the table frame 1. The surface of the fixed plate 4 is provided with a fixing component for limiting the flipped workbench frame 5. The first threaded shaft pin 8 of the fixing component is screwed into contact with the workbench frame 5 so that the first threaded shaft pin 8 is pressed against the workbench frame 5 under continuous screwing, thereby limiting the flipped workbench frame 5.

[0023] The fixing assembly includes a first threaded barrel 9 , which is disposed in the fixing plate 4 , and a first threaded shaft pin 8 is threadedly connected to the first threaded barrel 9 .

[0024] Stainless steel guide rails 11 are provided on both sides of the workbench frame 5 . The workbench frame 5 is rollingly connected to the load-bearing bearing 7 through the stainless steel guide rails 11 and slides into the bearing guide rails 10 in the sliding groove at the bottom of the table frame 1 .

[0025] A second threaded barrel 12 is disposed in the rotating plate 6 , and a second threaded shaft pin 13 is threadedly connected to the second threaded barrel 12 .

[0026] Positioning cylinders 14 are provided on both sides of the top of the table frame 1, and a card-type lock 15 is provided at one end of the fixing plate 4, and the card block on the surface of the card-type lock 15 is carded with the card groove 16 on the surface of the table frame 1, and the piston rod of the positioning cylinder 14 movably penetrates the table frame 1. When the workbench frame 5 slides into the table frame 1, the positioning cylinder 14 is started and controls the piston rod of the positioning cylinder 14 to contact with the workbench frame 5 to position the workbench frame 5.

[0027] The surface of the workbench frame 5 is provided with a handle 17 , and the workbench frame 5 can be conveniently pulled out of the platform frame 1 and lifted up by pulling the handle 17 .

[0028] When the workbench frame 5 needs to be cleaned, the workbench frame 5 is pulled out of the bearing guide rail 10 in the workbench frame 1 by the handle 17, so that the workbench frame 5 is slid out of the workbench frame 1, and the second threaded shaft pin 13 is rotated in the second threaded cylinder 12, so that the second threaded shaft pin 13 continues to move toward the workbench frame 5 and contacts the workbench frame 5, and the second threaded shaft pin 13 is pressed against the workbench frame 5 under continuous screwing, thereby increasing the sliding resistance of the workbench frame 5 so that the workbench frame 5 cannot be moved under the load-bearing The workbench frame 5 slides in the bearing 7. At this time, the workbench frame 5 can be lifted up to rotate on the surface of the fixed plate 4 through the rotating plates 6 on both sides.
