Description

Technical Field

[0001] The invention relates to the technical field of ultraviolet exposure machines, in particular to a multifunctional ultraviolet exposure machine. Background Art

[0002] UV exposure machine is a device that uses ultraviolet radiation technology for photocuring treatment. It is widely used in printing, coating, adhesive and other industries. Its working principle is to activate the curing agent by emitting ultraviolet rays of a specific wavelength, so that materials such as paint or glue can harden quickly, achieving the purpose of rapid drying and curing. Compared with traditional drying methods, UV exposure machines have the advantages of short drying time, good curing effect and low energy consumption, which can improve production efficiency. In addition, UV exposure machines are usually equipped with adjustment devices, which can adjust the intensity and time of ultraviolet rays according to the needs of different materials, thereby ensuring the consistency and stability of the treatment effect. It is one of the indispensable equipment in modern industry.

[0003] UV exposure machines are mainly divided into two types: large and small, each with different characteristics and applicable scenarios. Large UV exposure machines are usually equipped with conveyor belts, suitable for large-scale production lines, and can quickly process a large number of products in an automated process. The main advantage of this equipment is high efficiency, which can significantly increase production speed. However, its disadvantage is that it occupies a large area, requires a large amount of space resources for installation and maintenance, and has high site requirements, which may lead to increased investment in fixed assets and be restricted in some factories with limited space. On the other hand, small UV exposure machines are suitable for production environments with diverse uses and flexible layouts due to their small size and limited space. The advantages of this equipment are that it saves space, is easy to install, and is suitable for use in small work areas. However, its disadvantage is that it requires manual operation to pick up and assemble materials, which limits its degree of automation, resulting in low continuity and efficiency, and is not suitable for mass production.

[0009] The protection frame includes a protection frame, a limiting groove is opened at the center of the lower end surface of the protection frame, and the support frame includes a side baffle, a support pad is fixedly arranged at the lower end of the side baffle, and a soft rack is fixedly arranged at the center of the lower end surface of the support pad.

[0010] Preferably, a control panel is arranged on the front side of the upper end surface of the UV exposure machine body, a lower sealing ring is fixedly arranged on the periphery of the exposure part of the upper end surface of the UV exposure machine body, and support blocks are fixedly arranged at the four corners of the lower end surface of the UV exposure machine body.

[0011] Preferably, lower connecting blocks are fixedly sleeved on the lower ends of the outer rod bodies of the two synchronous telescopic rods, and the opposite ends of the two lower connecting blocks are fixedly arranged on both sides of the ultraviolet exposure machine body.

[0012] Preferably, the side baffle and the support pad are located inside the protective frame, the soft rack is located inside the limiting groove, and the support pad is formed by a plurality of plastic strips and cloth strips arranged in a cross-arrangement.

[0013] Preferably, a plurality of electric suction cups are fixedly provided on one side of the feeding plate away from the limiting block, and one end of the limiting rod away from the limiting block is fixedly connected to the feeding plate.

[0014] Preferably, one end of the transmission rod away from the transmission rotating rod is rotatably arranged with the second rocker rod, and the gear is meshingly connected with the soft rack.

[0015] Preferably, the front end of the main frame is fixedly arranged on the rear side of the ultraviolet exposure machine body, and the lower sealing ring and the upper sealing ring are both made of rubber material.

[0016] Working principle: When in use, a corresponding amount of unexposed material is placed inside the protective frame. In the process of manufacturing electronic components, especially in the application of flexible circuit boards and touch screens, in these production processes, conductive silver paste is often applied to the substrate by screen printing or spraying. The ultraviolet exposure machine can be used to cure these conductive silver pastes. These substrates are evenly arranged on the cloth strips on the support pad, isolated by the plastic strips of the support pad to achieve uniform arrangement, and then the output motor is started. The output end of the output motor rotates to drive the second rotating rod to rotate, and the rotation of the second rotating rod drives the first rotating rod to rotate through the transmission belt;

[0017] During the rotation of the No. 2 rotating rod, the transmission rotating rod rotates around the axis of the No. 2 rotating rod, similar to the rotation of the blade. The transmission rotating rod rotates and pulls the No. 2 swing rod through the transmission rod, so that the No. 2 swing rod swings left and right, and then drives the No. 1 swing rod to swing left and right synchronously through the transmission shaft. When the No. 1 swing rod swings to the highest point, it is perpendicular to the main frame. At this time, the material picking plate and the material picking port of the protective frame remain parallel, and a substrate can be sucked by an electric suction cup. When the No. 1 swing rod swings to the lowest point, the No. 1 swing rod is relatively parallel to the main frame. At this time, the electric suction cup sucks downward, the material picking plate fits the feed hole, and the substrate enters the feed hole, and then the ultraviolet exposure machine body is started to realize the curing operation;

[0018] When the No. 1 swing arm swings to the highest point, the synchronous telescopic rod extends, so that the cover body rises, which is convenient for manually taking out the cured substrate. When the No. 1 swing arm swings to the lowest point, the synchronous telescopic rod shortens, so that the upper sealing ring of the cover body fits with the lower sealing ring, thereby improving the sealing performance.

[0019] When the No. 1 rotating rod rotates, the gear drives the soft rack to move the support frame to one side, and the substrate on the support frame is moved a short distance, which makes it easier for the electric suction cup to absorb the substrate. The extended support pad and soft rack will sag without the support of the protection frame, and will not block the electric suction cup from picking up the substrate. At the same time, the limiting block and limiting rod are used to limit the angle of the picking plate when it moves, so that the picking plate can remain in a straight line at the highest and lowest points without skewing, thereby increasing stability.

[0020] The present invention provides a multifunctional ultraviolet exposure machine. It has the following beneficial effects:

[0021] The present invention provides a multifunctional ultraviolet exposure machine. The multifunctional ultraviolet exposure machine of the present invention adopts an efficient control frame design. Automatic gripping and discharging of a substrate can be achieved only through an output motor, which significantly reduces the energy consumption of the equipment, making it more energy-saving and environmentally friendly. The equipment uses a mechanical structure to carry out an extremely high degree of automation design. Through precise mechanical gripping and automatic discharging functions, the substrate can be continuously and efficiently processed without human intervention, thereby greatly improving the production and processing efficiency. In addition, the entire operation process is simplified, and the staff only needs to easily take out the substrate that has completed ultraviolet curing when the cover is opened. This design not only reduces the labor intensity and steps of manual labor, but also reduces the probability of human operation errors, thereby ensuring the stability of operation. At the same time, the present invention has a compact overall structure, and its compact design makes it occupy a very small area, which is very suitable for a production environment that requires flexible layout. The modular design concept also makes the equipment easier to install and move, and in the process of maintenance and repair, due to its simple and modular structure, the downtime and maintenance difficulty are greatly reduced, the stability and service life of the equipment are improved, thereby comprehensively improving the production efficiency and economic benefits.
