Description

Technical Field

[0001] This utility model relates to the field of light curing equipment technology, and in particular to a light curing equipment for moisture-curing dual-curing polyurethane hot melt adhesive. Background Technology

[0002] Photocuring equipment is a device that uses light of a specific wavelength to irradiate materials, triggering photochemical reactions within the materials and thus rapidly curing them. Photocuring can accelerate the curing speed of materials, shortening the production cycle and improving production efficiency compared to traditional natural curing methods.

[0003] The photocuring equipment for moisture-curing polyurethane hot melt adhesives is a curing device specifically designed for this special adhesive. Moisture-curing polyurethane hot melt adhesives combine the characteristics of hot melt adhesives that are heated and melted for application and moisture-curing adhesives. At the same time, the curing process can be accelerated by light. After the polyurethane hot melt adhesive is applied, a photochemical reaction of the adhesive is quickly initiated, allowing it to initially cure and set in a short time. Then, with the help of the humidity in the environment, it is further deeply cured, thereby achieving a high-quality bonding effect.

[0004] In traditional photocuring equipment, the light source generates a large amount of heat during the photocuring process. The continuous high temperature not only affects the lifespan and luminous stability of the light source, but also causes the hot melt adhesive to soften and deteriorate prematurely, affecting the curing effect. To solve this problem, existing technologies use heat dissipation fins around the light source, and heat pipes quickly conduct heat to the heat dissipation fins, which are then removed by an air cooling system to ensure that the equipment operates within a stable temperature range. However, in actual use, when the conveyor belt transports the workpiece for photocuring, the vibration of the conveyor belt causes the workpiece to shift left and right on the conveyor belt. This results in an uncertain position of the workpiece when it reaches the light-curing area, affecting the curing effect of the moisture-curing polyurethane hot melt adhesive and causing unstable product quality.

The moisture supply component 208 includes a water tank 2081 for storing water. A water source is provided for the humidifier 2082. The bottom of the water tank 2081 is fixedly connected to the top of the support platform 5, so that the water tank 2081 is stably installed on the support platform 5.

A humidifying cover 2083 is provided on the outside of the humidifier 2082. The humidifying cover 2083 is used to guide and concentrate the water vapor, so that it is evenly released around the workpiece. The top of the humidifying cover 2083 is fixedly connected to the bottom left side of the support platform 5 to ensure the stable installation of the humidifying cover 2083, so that the water vapor can accurately act on the workpiece.

[0038] Specifically, the adjustment mechanism 2, in conjunction with the gantry frame 201 and the bidirectional lead screw 202, can adjust the spacing of the guide plate 204 as needed to ensure that the workpiece is transported in the center. The moisture supply component 208 provides a moisture curing environment for the hot melt adhesive. The lifting component 210 can be adapted to different workpiece heights. All components work together to improve the curing effect and product quality of the moisture-curing polyurethane hot melt adhesive.

[0039] Reference Figure 5 , Figure 6 and Figure 7 The lighting assembly 209 includes a lighting lamp group 2091, which emits light to cure the moisture-curing polyurethane hot melt adhesive, ensuring that the hot melt adhesive is cured and formed. The outer wall of the lighting lamp group 2091 is fixedly connected to the bottom of the support platform 5, so that the lighting lamp group 2091 is stably installed in a suitable position to provide illumination for the workpiece below. Ventilation slots 2093 are provided on the front and rear sides of the support platform 5, which provide channels for air circulation and facilitate heat dissipation. A heat dissipation fin group 2092 is fixedly connected to the top of the lighting lamp group 2091. The heat dissipation fin group 2092 increases the heat dissipation area and absorbs the heat generated by the lighting lamp group 2091 during operation. Two cooling fans 2094 are fixed on the front and rear sides of the inner wall of the ventilation slot 2093. The operation of the cooling fans 2094 accelerates the airflow and quickly dissipates the heat absorbed by the heat dissipation fin group 2092, ensuring that the working environment temperature of the lighting lamp group 2091 is suitable.

[0040] The lifting assembly 210 includes multiple guide support columns 2101. The guide support columns 2101 provide guidance for the lifting of the support platform 5, ensuring smooth lifting.

Lifting columns 2102 are slidably connected to the middle of the inner walls of both fixed plates 4. The lifting columns 2102 slide within the fixed plates 4, driving the support platform 5 to lift. The tops of the two lifting columns 2102 are fixedly connected to the front and rear sides of the bottom of the support platform 5, ensuring that the support platform 5 can move with the lifting columns 2102. The inner wall of the lifting column 2102 is threaded with threaded rods 2103. When the threaded rods 2103 rotate, they drive the lifting column 2102 to move along its axial direction. The bottom ends of the two threaded rods 2103 are fixedly connected with transmission bevel gears 2104. The transmission bevel gears 2104 are used to transmit power and change the direction of power. The two fixed plates 4 are fixedly connected with servo motors 2105 on opposite sides. The servo motors 2105 provide the power source for the lifting action. The output ends of the two servo motors 2105 are fixedly connected with drive bevel gears 2106. The drive bevel gears 2106 transmit the power of the servo motors 2105 to the transmission bevel gears 2104. The two drive bevel gears 2106 mesh with the corresponding transmission bevel gears 2104 to achieve effective power transmission, so that the threaded rods 2103 rotate and drive the support platform 5 to rise and fall.

[0041] Specifically, the illumination lamp assembly 2091 is fixed to the bottom of the support platform 5 to provide curing light. The heat dissipation fin assembly 2092 works with the cooling fan 2094 to efficiently dissipate heat through the ventilation slot 2093, ensuring the stable operation of the illumination lamp assembly 2091. The lifting assembly 210 is driven by the servo motor 2105 through the guide support column 2101 and the lifting column 2102 to achieve precise lifting of the support platform 5, adapting to the needs of different workpieces.

[0042] Reference Figure 1 , Figure 2 and Figure 3The cleaning mechanism 3 includes a cleaning motor 301, which provides power to clean dust from the surface of the conveying component 1, ensuring effective cleaning. The rear of the cleaning motor 301 is fixedly connected to the front right end of the conveying component 1, ensuring its stable installation and facilitating the driving of subsequent components. A rotating shaft 302 is fixedly connected to the output end of the gantry 201. The rotating shaft 302 rotates under the drive of the cleaning motor 301, thereby driving the brush 303 to work. The brush 303 is fixedly connected to the outer wall of the rotating shaft 302. As the rotating shaft 302 rotates, the brush 303 cleans the bottom of the conveying component 1 to remove surface dust. The outer wall of 02 is rotatably connected to bearing seats 304 on both the front and rear sides. The bearing seats 304 support the rotating shaft 302 and ensure the stability of the rotation of the rotating shaft 302. The tops of the two bearing seats 304 are fixedly connected to the front and rear ends of the bottom right side of the conveying component 1, so that the bearing seats 304 are firmly installed on the conveying component 1, thereby stably supporting the rotating shaft 302. The outer wall of the brush 303 is in contact with the bottom of the conveying component 1, ensuring that the brush 303 can effectively clean the dust on the surface of the conveying component 1 and achieve the cleaning purpose. A drying component 305 is provided on the right side of the brush 303. The drying component 305 is used to dry the cleaned conveying component 1 to prevent the dust from re-adhering due to moisture.

[0043] The drying assembly 305 includes two lamp holders 3051, which are used to fix the drying lamp 3052 in a suitable position for drying. The inner walls of the two lamp holders 3051 are respectively fixedly connected to the front and rear ends of the right side of the conveying component 1, so that the drying assembly 305 is stably installed on the conveying component 1. The same drying lamp 3052 is fixedly connected to the adjacent side of the two lamp holders 3051. The drying lamp 3052 emits heat to dry the conveying component 1, ensuring that the surface of the conveying component 1 is dry.

[0044] Specifically, the cleaning motor 301 provides power to drive the rotating shaft 302 to rotate the brush 303, effectively cleaning the dust on the surface of the conveying component 1, reducing the impact of dust on the workpiece and the production process. The bearing seat 304 ensures the stable rotation of the rotating shaft 302. The drying component 305 dries the conveying component 1 after cleaning to prevent the dust from adhering again due to moisture, ensuring the continuous cleanliness of the conveying component 1, creating favorable conditions for the light curing of the moisture-curing polyurethane hot melt adhesive, and improving product quality.

[0045] Reference Figure 1 , Figure 5 and Figure 7The heat dissipation fin assembly 2092 is equipped with filters 6 on both the front and rear sides. The filters 6 are used to block dust and impurities from entering the heat dissipation area and prevent dust from adhering to the heat dissipation fin assembly 2092 and affecting the heat dissipation effect. The outer walls of the two filters 6 are fixedly connected to the front and rear sides of the inner wall of the ventilation slot 2093, so that the filters 6 are firmly installed in the ventilation slot 2093 and effectively play their filtering role. The inner walls of the two fixing plates 4 are provided with multiple limiting slide grooves 7. The limiting slide grooves 7 provide sliding tracks for the limiting sliders 8, guiding the guide support column 2101 to rise and fall smoothly in a specific direction. Multiple limiting sliders 8 are fixedly connected at equal intervals around the outer walls of the multiple guide support columns 2101. The limiting sliders 8 cooperate with the limiting slide grooves 7 to enhance the stability of the guide support column 2101 during the rising and falling process and prevent it from shaking. The outer walls of the multiple limiting sliders 8 are slidably connected to the inner walls of the corresponding limiting slide grooves 7, ensuring that the limiting sliders 8 can slide smoothly in the limiting slide grooves 7, thereby ensuring that the guide support column 2101 drives the support platform 5 to rise and fall smoothly.

[0046] Specifically, the filter screen 6 is set on the front and rear sides of the heat dissipation fin assembly 2092 and fixed on the inner wall of the ventilation slot 2093, effectively blocking dust and maintaining the good heat dissipation performance of the heat dissipation fins. The limiting slide groove 7 cooperates with the limiting slider 8. The former is opened on the inner wall of the fixed plate 4, and the latter is evenly distributed on the outer wall of the guide support column 2101 to ensure the smooth lifting and lowering of the guide support column 2101 and improve the stability of equipment operation.

[0047] Working principle: When using the photocuring equipment, first adjust the adjusting mechanism 2 and the lifting assembly 210 according to the size of the workpiece to be cured. Start the servo motor 206, and its output end rotates to drive the bidirectional lead screw 202 to rotate. Since the front and rear sides of the outer wall of the bidirectional lead screw 202 are threaded with sliding blocks 203, and the top left and right sides of the guide plate 204 are fixedly connected to the bottom of the corresponding sliding blocks 203, the sliding blocks 203 will move towards or away from each other along the bidirectional lead screw 202, thereby driving the guide plate 204 to move, thus adjusting the distance between the two guide plates 204. The distance is adjusted to ensure the workpiece remains centered during transport, preventing lateral shifts caused by conveyor belt vibration. Simultaneously, servo motor 2105 is activated, its output driving bevel gear 2106 to rotate, which in turn drives transmission bevel gear 2104, causing the threaded rod 2103 to rotate. Since the inner wall of the lifting column 2102 is threadedly connected to the threaded rod 2103, and the guide support column 2101 guides and supports the support platform 5, the support platform 5 adjusts its height as the lifting column 2102 rises and falls, ensuring workpieces of different sizes are positioned appropriately. The process involves receiving both moisture supply and light curing to ensure the curing effect of the moisture-curing polyurethane hot melt adhesive and improve product quality stability. Next, the workpiece is placed on the top left side of the conveyor component 1, which then begins operation, moving the workpiece to the right. When the workpiece reaches below the moisture supply component 208, the water in the water tank 2081 is converted into water vapor by the humidifier 2082 and released around the workpiece through the humidification hood 2083, providing the moisture-curing environment for the moisture-curing polyurethane hot melt adhesive. Subsequently, the workpiece immediately reaches below the light assembly 209, and the light group 2091 is turned on. The light emits light to cure the hot melt adhesive on the workpiece. At the same time, to ensure the normal operation of the light lamp assembly 2091, the heat sink assembly 2092 absorbs the heat generated by the light lamp assembly 2091. The cooling fan 2094 accelerates air circulation through the ventilation slot 2093 to expel the heat. The adjustment mechanism 2 ensures that the workpiece is centered during the conveyor and avoids deviation due to conveyor belt vibration. The lifting component 210 is used to adapt to different workpiece heights. The workpiece is cured in conjunction with the moisture supply component 208 and the light component 209, which solves the problems of uncertain workpiece position and poor curing effect, and improves the stability of product quality.

[0048] Furthermore, when the conveyor component 1 is running, the conveyor belt in the conveyor component 1 needs to pass through the moisture supply component 208, causing the surface of the conveyor belt to become wet. At this time, the drying component 305 starts to work, and the drying lamps 3052 on the two lamp holders 3051 are turned on, emitting heat to dry the surface of the conveyor component 1. Because the humid environment makes it easier for dust and impurities to adhere, the drying process can reduce the adhesion of impurities caused by moisture, preparing for subsequent cleaning. Subsequently, the conveyor component 1 enters the working area of ​​the cleaning mechanism 3, and the cleaning motor 301 is started. Its output end rotates, driving the shaft 302 connected to it to rotate. Since the outer wall of the shaft 302 is fixedly connected to the brush 303, and the shaft 302 is stably supported on the bottom right side of the conveyor component 1 by the bearing seats 304 on the front and rear sides, the brush 303 rotates synchronously with the shaft 302. The rotating brush 303 is in close contact with the bottom of the conveyor component 1, brushing off the loosened dust and impurities after drying, thereby achieving the purpose of cleaning the surface of the conveyor component 1 and ensuring that the conveyor component 1 will not affect the product quality due to surface impurities during the subsequent conveying of workpieces.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
