Description

Technical Field

[0001] This utility model belongs to the field of UV curing equipment technology, specifically relating to a UV curing machine structure with high-efficiency heat dissipation. Background Technology

[0002] A UV curing machine is an industrial device that uses ultraviolet (UV) light to rapidly cure coatings, inks, or adhesives. It mainly consists of three parts: a conveyor belt, a curing chamber, and a cabinet. The conveyor belt continuously transports the workpiece to be cured into the curing chamber. High-power UV lamps are installed inside the curing chamber, emitting ultraviolet light to trigger a photochemical reaction in the material, achieving instant curing. The cabinet houses the power supply system and control devices, which can precisely adjust parameters such as conveyor speed, light intensity, and temperature to ensure efficient and stable curing. The UV lamps in the curing chamber generate a large amount of heat during operation. Insufficient heat dissipation can lead to excessively high lamp temperatures, shortening their lifespan or causing light decay, reducing curing efficiency. Simultaneously, high temperatures may cause the cured material to deform or the reaction to run out of control, affecting product quality. The high-power power supply in the cabinet operates under high load to drive the UV lamps for extended periods. Poor heat dissipation can easily cause overheating of electronic components, even burning out circuits and threatening equipment safety.

[0003] Therefore, in existing technologies, exhaust fans are typically installed separately in the curing chamber and the cabinet to quickly expel the high-temperature hot air generated inside. However, these separate heat dissipation structures may interfere with each other, reducing overall heat dissipation efficiency, affecting the stability of the UV curing process, and the maintenance costs of the two heat dissipation systems are also high.

[0029] Reference Figures 1-5 As shown, this embodiment provides a UV curing machine structure with high-efficiency heat dissipation, including a curing chamber, a conveyor belt, a cabinet, and a heat dissipation module;

[0030] The curing chamber is fixed to the upper side of the top plate of the cabinet. The curing chamber includes a curing box and a UV lamp assembly, with the UV lamp assembly installed inside the curing box. The conveyor belt is installed on the upper side of the top plate of the cabinet and passes through the curing box. The top plate of the cabinet has ventilation holes connecting the cabinet and the curing box.

[0031] The heat dissipation module includes a heat dissipation controller and a first temperature sensor, a second temperature sensor, a first bidirectional fan, a second bidirectional fan, and a third bidirectional fan, all electrically connected to the heat dissipation controller. The first temperature sensor is installed inside the curing chamber, and the second temperature sensor is installed inside the cabinet. The first bidirectional fan is installed on the inner top of the curing chamber, and the second bidirectional fan and the third bidirectional fan are installed on the left and right sides inside the cabinet, respectively. The heat dissipation controller is used to acquire the temperature data from the first temperature sensor and the second temperature sensor, and to control the speed and direction of rotation of the first bidirectional fan, the second bidirectional fan, and the third bidirectional fan.

[0032] In this embodiment, a motor is installed on one side of the conveyor belt to drive its rotation. The cabinet houses a main power supply and a control system. The control system controls the rotation of the conveyor belt and the power of the UV lamps, while the main power supply provides operating power to the control system, the UV lamps, and the conveyor belt.

[0033] As a preferred embodiment, four ventilation holes are provided, distributed at the four corners of the lower side of the curing chamber, and the ventilation holes are circular holes with a diameter of 50mm.

[0034] This embodiment provides a high-efficiency heat dissipation UV curing machine structure. By installing temperature sensors in the curing chamber and cabinet respectively, the temperature of the curing chamber and cabinet can be obtained. Bidirectional fans are installed on the top of the curing chamber and on both sides of the cabinet. At the same time, ventilation holes connecting the curing chamber and cabinet are provided. Thus, the temperature data of the curing chamber and cabinet can be obtained through the heat dissipation controller, and the rotation direction and speed of the three bidirectional fans can be controlled. The heat dissipation duct and heat dissipation intensity in the UV curing machine can be flexibly adjusted to adapt to different temperature conditions in the curing chamber and cabinet, improve the overall heat dissipation efficiency of the UV curing machine, increase the stability of the UV curing process, and reduce the maintenance cost of the heat dissipation system.

[0035] In this embodiment, the heat dissipation module further includes three H-bridge drivers, and the heat dissipation controller is connected to and controls the first bidirectional fan, the second bidirectional fan and the third bidirectional fan through the three H-bridge drivers respectively.

[0036] In this embodiment, the heat dissipation module includes a heat dissipation controller, a first temperature sensor, a second temperature sensor, a first bidirectional fan, a second bidirectional fan, a third bidirectional fan, a first H-bridge driver, a second H-bridge driver, a third H-bridge driver, a power adapter, an MP1584 module, and an AMS1117 module. Specifically, the power adapter converts the mains power to 12V / 5A DC power and powers the H-bridge driver; the MP1584 module converts the 12V / 5A DC power to 5V; and the AMS1117 module converts the 5V power to 3.3V and powers the heat dissipation controller and temperature sensors. The heat dissipation controller is an MCU, specifically an STM32F103C8T6. The temperature sensor is a DS18B20, and the H-bridge driver is a DRV8873. The bidirectional fan is a 120mm bidirectional fan. The heat dissipation controller has its PA0 terminal connected to the first temperature sensor to acquire temperature data, its PA1 terminal connected to the second temperature sensor to acquire temperature data, its PA8 terminal connected to the PWM terminal of the first H-bridge driver, its PA9 terminal connected to the DIR terminal of the first H-bridge driver, its PA10 terminal connected to the PWM terminal of the second H-bridge driver, its PA11 terminal connected to the DIR terminal of the second H-bridge driver, its PA15 terminal connected to the PWM terminal of the third H-bridge driver, and its PB8 terminal connected to the DIR terminal of the third H-bridge driver.

Thus, the heat dissipation controller controls the rotation direction of the corresponding bidirectional fan by controlling the connected DIR terminal and adjusts the speed of the corresponding bidirectional fan by controlling the connected PWM terminal.

[0037] In some embodiments of this utility model, the heat dissipation controller controls the second bidirectional fan and the third bidirectional fan to have one intake and one exhaust, and controls the first bidirectional fan to exhaust; when the average temperature detected by the first temperature sensor and the second temperature sensor is low, the speed of the first bidirectional fan, the second bidirectional fan and the third bidirectional fan is reduced, and when the average temperature detected by the first temperature sensor and the second temperature sensor is high, the speed of the first bidirectional fan, the second bidirectional fan and the third bidirectional fan is increased.

[0038] In other embodiments of this invention, the heat dissipation controller controls one of the second and third bidirectional fans to intake air and the other to exhaust air, while controlling the first bidirectional fan to exhaust air. Furthermore, when both the first and second temperature sensors detect low temperatures, the speeds of the first, second, and third bidirectional fans are reduced; when both the first and second temperature sensors detect high temperatures, the speeds of the first, second, and third bidirectional fans are increased. When the temperature detected by the first temperature sensor is high and the temperature detected by the second temperature sensor is low, the first bidirectional fan is controlled to exhaust air, while the second and third bidirectional fans intake air. When the temperature detected by the first temperature sensor is low and the temperature detected by the second temperature sensor is high, the first bidirectional fan is controlled to intake air, while the second and third bidirectional fans exhaust air.

[0039] In this embodiment, the cabinet is a cubic structure, including a top plate, a bottom plate, a left side plate, a right side plate, a front side plate, and a rear side plate; the curing box includes a top panel, a left panel, a right panel, a front panel, and a rear panel, with notches formed on the lower sides of the left and right panels of the curing box, through which the conveyor belt passes.

The airflow paths formed by the first bidirectional fan and the second bidirectional fan are horizontal and located on the same straight line.

[0041] The third bidirectional fan is fixed to the middle of the upper panel of the curing box. The airflow path formed by the third bidirectional fan is vertical and is located on the same vertical plane as the airflow paths formed by the first bidirectional fan and the second bidirectional fan.

[0042] Ventilation openings are provided at the corresponding curing enclosures or racks for the first, second, and third bidirectional fans. The reference numerals on the accompanying drawings of the instruction manual indicate the corresponding inner bidirectional fans for the first, second, and third bidirectional fans.

[0043] As a preferred embodiment, it further includes a left baffle and a right baffle; the left baffle has a positioning knob in the middle section, and its upper side is bent to form a latch, which is vertically inserted into a slot on the left panel of the curing chamber; the right baffle has a positioning knob in the middle section, and its upper side is bent to form a latch, which is vertically inserted into a slot on the right panel of the curing chamber. The left and right baffles allow for flexible passage of cured products of different heights while maintaining the relative enclosure of the curing chamber, improving the UV curing effect and forming a heat dissipation duct.

[0044] As a further improvement to this embodiment, the rear baffle of the curing chamber forms multiple horizontal stamped ventilation strips, the openings of which face downwards.

[0045] The front panel of the cabinet is equipped with a hinge at one end and a fastener at the other end. This allows the cabinet to be opened and closed via the front panel.

[0046] The cabinet has multiple omnidirectional casters on its lower side, each caster equipped with a locking mechanism. The cabinet also has multiple leveling feet on its lower side. Specifically, four omnidirectional casters are located at the four corners of the cabinet's base plate; four leveling feet are located along the four sides of the cabinet's base plate.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
