Description

Technical Field

[0001] This utility model relates to the field of micro-nano photopolymerization printing technology, specifically a precision alignment platform for micro-nano photopolymerization printing equipment. Background Technology

[0002] Micro-nano photopolymerization printing technology is a high-precision manufacturing technology that uses ultraviolet light or other light sources to precisely irradiate photosensitive resin, causing it to solidify layer by layer to form three-dimensional micro-nano structures. This technology has broad application prospects in fields such as microelectronics and optical components. However, in order to ensure its printing accuracy, the relative positional accuracy between the printing platform and the light source is required to be high. In order to align the printing platform under the light source, the development of a precision alignment platform for micro-nano photopolymerization printing equipment is of great practical significance.

[0003] A precision alignment platform, as described in reference announcement number CN219075578U, includes a base with symmetrically arranged connecting frames and first sliding grooves. A first electric slide rail is installed within each first sliding groove. A slider is installed at the bottom of each connecting frame and is fixedly connected to the first electric slide rail. Mounting plates are mounted on both sets of connecting frames. This alignment platform, through the inclusion of an adjustment component and a servo motor, can drive a worm gear to rotate counterclockwise and clockwise. When the worm gear rotates, it drives a connecting column to rotate via a worm wheel. When the connecting column rotates, an annular plate rotates within the connecting plate, simultaneously adjusting the left-right angle of the loading plate. The first electric slide rail moves the connecting frame left and right on the base, while the second electric slide rail moves the mounting plate back and forth within the connecting frame. Simultaneously, the loading platform adjusts its position forward, backward, left, and right along with the first and second electric slide rails. As can be seen from the above, while this alignment platform can be well applied, it is generally inconvenient to adjust the overall height of the platform, making it difficult for personnel of different heights to operate and operate, thus exhibiting certain limitations. Utility Model Content

[0004] The purpose of this invention is to provide a precision alignment platform for a micro-nano photopolymerization printing device, in order to solve the problem mentioned in the background art that although the alignment platform can be used well, it is usually not convenient to adjust the overall height of the platform, which makes it difficult for people of different heights to operate and work, and thus has certain limitations.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision alignment platform for a micro-nano photopolymerization printing device, comprising a movable base, a base plate fixedly mounted on the top of the movable base, a lower connecting plate above the base plate, an upper connecting plate above the lower connecting plate, a nut seat fixedly mounted at the center of the bottom end of the upper connecting plate, a limiting frame slidably connected to the outer side of the nut seat, the bottom end of the limiting frame being fixedly connected to the top of the lower connecting plate, a limiting plate at the top of the lower connecting plate on one side of the nut seat, a first screw threadedly connected to one side of the nut seat, one end of the first screw penetrating the limiting plate and mounted with a first handle, lower connecting seats on both sides of the top of the base plate, upper connecting seats on both sides of the bottom end of the lower connecting plate, a lifting cylinder mounted on the top of the lower connecting seat, the top of the lifting cylinder being connected to the bottom end of the upper connecting seat, a control panel mounted on the outer wall of one side of the movable base, the output end of the microcontroller inside the control panel being electrically connected to the input end of the lifting cylinder.

[0008] Preferably, a side connecting plate is fixed on the outer wall of one side of the upper connecting plate, and a limiting cylinder is provided on the outer wall between the side connecting plate and a positioning seat. One end of the second screw passes through the positioning seat, the limiting cylinder and the side connecting plate in sequence and is equipped with a second handle. By rotating the second handle, the second screw can be driven to rotate.

[0009] Preferably, a nut assembly is threaded onto the outer wall of the second screw, the top end of which is connected to the bottom end of the platform. The nut assembly slides along the outer wall of the second screw to adjust the position of the platform.

[0010] Preferably, two rollers are rotatably mounted on the outer walls of both sides of the movable base, and a geared motor is mounted on the inner walls of both sides of the movable base. The input end of the geared motor is electrically connected to the output end of the microcontroller inside the control panel.

[0011] Compared with the prior art, the beneficial effects of this utility model are: the precision alignment platform of the micro-nano photopolymerization printing equipment not only improves the applicability of the alignment platform, but also makes it easy to accurately align the designated area of ​​the platform under the light source of the printing instrument, and achieves the purpose of easy transfer and movement of the precision alignment platform.

The position of the platform can be adjusted back and forth. Then, by rotating the second handle, the second screw is driven to rotate between the positioning seats. At this time, the nut pair slides on the outer wall of the second screw, and drives the platform to slide on the top of the slide rail, so as to adjust the position of the platform left and right, so as to easily and accurately align the designated area of ​​the platform below the light source of the printing instrument.

[0014] (3) By synchronizing the start of two geared motors, the two rollers are driven to rotate, and the other two rollers are used to move the mobile base on the ground for sliding and transport, thereby achieving the purpose of easily transporting and moving the precision alignment platform.

The input end of the geared motor 23 is electrically connected to the output end of the microcontroller inside the control panel 3, and one end of the geared motor 23 extends to the outside of the movable base 1 and is connected to the inner wall of one of the rollers 2.

[0022] In use, the geared motor 23 is configured to drive the roller 2 to rotate;

[0023] A base plate 4 is fixedly installed on the top of the movable base 1. A lower connecting plate 7 is provided above the base plate 4. An upper connecting plate 11 is provided above the lower connecting plate 7. Two slide rails 15 are provided at the top of the upper connecting plate 11. A platform 16 is slidably connected to the top of the slide rails 15.

[0024] In use, the slide rail 15 is used to allow the platform 16 to be moved and positioned.

[0025] Two positioning seats 13 are provided at the top of the upper connecting plate 11 between the slide rails 15, and a second screw 17 is rotatably installed on the inner wall between the positioning seats 13.

[0026] In use, the second screw 17 is provided to accommodate the nut assembly 22.

[0027] A side connecting plate 12 is fixed on the outer wall of one side of the upper connecting plate 11. A limiting cylinder 14 is provided on the outer wall between the side connecting plate 12 and a positioning seat 13. One end of the second screw 17 passes through the positioning seat 13, the limiting cylinder 14 and the side connecting plate 12 in sequence and is equipped with a second handle 18.

[0028] In use, the second screw 17 is driven to rotate by rotating the second handle 18;

[0029] A nut pair 22 is threaded onto the outer wall of the second screw 17, and the top end of the nut pair 22 is connected to the bottom end of the platform 16.

[0030] In use, the position of the platform 16 can be adjusted by sliding the nut pair 22 on the outer wall of the second screw 17.

[0031] A nut seat 20 is fixedly installed at the center of the bottom end of the upper connecting plate 11. A limit frame 19 is slidably connected to the outside of the nut seat 20. The bottom end of the limit frame 19 is fixedly connected to the top end of the lower connecting plate 7.
