Technical Field

[0001] This utility model relates to the field of photolithography technology, and in particular to a photolithography forming device for patterned microfluidic devices. Background Technology

[0002] Microfluidic devices, due to their miniaturization, integration, and high throughput, have shown broad application prospects in fields such as biomedicine, chemical analysis, and environmental monitoring. Photolithography is one of the key processes for manufacturing microfluidic devices. It forms fine patterns on a substrate, thereby constructing structures such as microchannels and microreaction chambers.

[0003] Existing photolithography forming equipment has the problem of inconvenience in positioning the processing material during processing, so a photolithography forming equipment with patterned microfluidic devices is needed. Utility Model Content

[0004] The purpose of this invention is to provide a photolithography forming device for patterned microfluidic devices, which solves the problem of inconvenient material positioning in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a photolithography forming apparatus for patterned microfluidic devices, comprising a base, a processing stage mounted on the top of the base, mounting plates symmetrically arranged on both sides of the processing stage, a positioning bolt penetrating the center of the mounting plate, a limiting groove formed on the top of the processing stage, a fixing shaft fixed in the center of the limiting groove, an adjusting component rotatably mounted on the outer side of the fixing shaft, a baffle plate disposed below the adjusting component, the baffle plate being welded to the processing stage, and a pusher abutting against the front side of the adjusting component. At the tail end of the rod, a limit plate is fixed to the front end of the push rod. Guide plates are symmetrically arranged on both sides of the inner wall of the limit plate. A guide rod is arranged parallel to the inner side of the guide plate. The top end of the guide rod is fixedly connected to the inner wall of the limit plate. A spring passes through the outer side of the guide rod. A workpiece is placed inside the limit groove. An arc-shaped groove is opened inside the processing table. An arc-shaped frame is slidably installed inside the arc-shaped groove. A push plate is fixed to the right end of the arc-shaped frame. A pressing plate is fixed to the left end of the arc-shaped frame. A processing arm is arranged above the processing table.

[0006] This utility model further illustrates that the processing table is detachable from the base via a mounting plate and positioning bolts, and the mounting plate is symmetrically arranged about the central axis of the processing table.

[0007] The present invention further explains that the contact surface between the adjusting member and the push rod is arranged in a polygonal arc shape, and the adjusting member forms a rotating structure with the processing table through a fixed shaft, and the range of motion of the adjusting member is 0° to 90°.

[0008] This utility model further explains that the limiting plate forms a transmission structure with the push rod and the adjusting member, and the limiting plate forms a sliding structure with the processing table with the guide rod.

[0009] This utility model further illustrates that the workpiece is connected to the processing table via a limiting plate, and the limiting plate and the workpiece are arranged in parallel.

[0010] The present invention further explains that the pressing plate is integrally set with the ejector plate through an arc-shaped frame, and the ejector plate moves in an arc shape along the inside of the arc-shaped groove through the arc-shaped frame, wherein the weight of the ejector plate is greater than that of the pressing plate.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. By setting a limiting plate, the workpiece is placed inside the limiting groove during use. The adjusting component is manually controlled to rotate around the fixed axis, allowing the adjusting component to follow different rotation angles. The adjusting component contacts the push rod through the outer plane edge at different angles, which can accommodate workpieces of different widths for locking and limiting. The push rod is conveniently pushed to drive the limiting plate to slide back and forth through the guide plate. A spring and guide rod are set. When sliding forward, the spring is stretched, and the relative force of the adjusting component effectively ensures the clamping operation. When the adjusting component rotates to a vertical angle, the push rod is reset by the spring, allowing the front limiting plate to separate from the workpiece, completing the disassembly of the workpiece. The disassembly and assembly are convenient, which is conducive to the positioning of the workpiece and facilitates the subsequent processing operation of the workpiece by the top processing arm without displacement.

[0013] 2. By setting up an arc-shaped frame, after processing is completed, pressing the button causes the bottom arc-shaped frame to slide along the inside of the arc-shaped groove. At this time, the ejector plate rises under the control of the arc-shaped frame, thereby lifting the processed part at the top. At this time, the processed part separates from the limiting plate, and the lifting further improves the convenience of taking it out. When the hand is released, the ejector plate, made of a heavier steel sheet, automatically presses down to a horizontal state with the bottom of the limiting groove, ensuring the stability of the subsequent processed parts.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] like Figure 1-3 As shown in the figure, a photolithography forming apparatus for patterned microfluidic devices includes a base 1, a processing stage 2 mounted on the top of the base 1, mounting plates 3 symmetrically arranged on both sides of the processing stage 2, a positioning bolt 4 penetrating the middle of the mounting plate 3, a limiting groove 5 formed on the top of the processing stage 2, a fixing shaft 6 fixed in the middle of the limiting groove 5, an adjusting component 7 rotatably mounted on the outer side of the fixing shaft 6, a baffle 8 arranged below the adjusting component 7, the baffle 8 being welded to the processing stage 2, the tail end of a push rod 9 being attached to the front side of the adjusting component 7, and a limiting component fixed at the front end of the push rod 9. The plate 10 has guide plates 11 symmetrically arranged on both sides of its inner wall. Guide rods 12 are arranged parallel to each other on the inner side of the guide plates 11. The top of the guide rods 12 is fixedly connected to the inner wall of the plate 10. A spring 13 passes through the outer side of the guide rods 12. A workpiece 14 is placed inside the limiting groove 5. An arc-shaped groove 15 is opened inside the processing table 2. An arc-shaped frame 16 is slidably installed inside the arc-shaped groove 15. An ejector plate 17 is fixed to the right end of the arc-shaped frame 16. A pressing plate 18 is fixed to the left end of the arc-shaped frame 16. A processing arm 19 is arranged above the processing table 2.

[0020] The processing table 2 is detachable from the base 1 via the mounting plate 3 and the positioning bolt 4. The mounting plate 3 is symmetrically arranged about the central axis of the processing table 2. The detachable arrangement ensures the convenience of maintenance and replacement of the processing table 2.

[0021] The contact surface between the adjusting component 7 and the push rod 9 is set with a polygonal arc shape, and the adjusting component 7 forms a rotating structure with the processing table 2 through the fixed shaft 6. The range of motion of the adjusting component 7 is 0° to 90°. The adjusting component 7 can follow different rotation angles and contact the push rod 9 through the outer plane edge at different angles, which can adapt to the engagement and limiting of processing parts 14 of different widths.

[0022] The limiting plate 10 forms a transmission structure with the push rod 9 and the adjusting member 7, and the limiting plate 10 forms a sliding structure with the processing table 2 with the guide rod 12, which can control the limiting plate 10 and the processing member 14 to squeeze or separate from each other.

[0023] The workpiece 14 is engaged with the worktable 2 by means of the limiting plate 10, and the limiting plate 10 is set parallel to the workpiece 14, which facilitates the assembly and disassembly of the workpiece 14, facilitates the positioning of the workpiece 14, and facilitates the subsequent processing operation of the top processing arm 19 on the workpiece 14 without displacement.

[0024] The push plate 18 is integrated with the ejector plate 17 via the arc frame 16. The ejector plate 17 moves along the arc inside the arc groove 15 via the arc frame 16. The ejector plate 17 is heavier than the push plate 18. After the workpiece 14 is separated from the limiting plate 10, it can be lifted by the ejector plate 17 to further improve the ease of removal and make it easier to pick up.

[0025] Working principle: First, the workpiece 14 is placed inside the limiting groove 5. The adjusting component 7 is rotated around the fixed shaft 6 by manual control. The adjusting component 7 can follow different rotation angles and contact the push rod 9 through the outer plane edge at different angles. This can accommodate workpieces 14 of different widths for locking and limiting. The push rod 9 is pushed to drive the limiting plate 10 to slide back and forth through the guide plate 11. A spring 13 and a guide rod 12 are provided. When sliding forward, the spring 13 is stretched, and the relative force of the adjusting component 7 effectively ensures the clamping operation. When the adjusting component 7 rotates to a vertical angle, the push rod 9 is reset by the spring 13, so that the front limiting plate 10 and the workpiece 14 are separated, completing the disassembly of the workpiece 14. The disassembly and assembly are convenient and facilitate the positioning of the workpiece 14. This makes it easy for the top processing arm 19 to process the workpiece 14 without displacement.

[0026] Next, after processing is completed, by pressing the button 18, the bottom arc frame 16 is driven by the button 18 to slide along the inside of the arc groove 15. At this time, the ejector plate 17 is raised by the arc frame 16 to lift the processed part 14 at the top. At this time, the processed part 14 is separated from the limiting plate 10, and the lifting further improves the convenience of taking it out. When the hand is released, the ejector plate 17, which is made of a heavier steel sheet, automatically presses down to a horizontal state with the bottom of the limiting groove 5 to ensure the stability of the subsequent processing part 14.
