Description

Technical Field

[0001] This utility model relates to the field of composite resin production technology, specifically a composite resin curing degree control device. Background Technology

[0002] In the field of composite resin material processing, traditional processes face several technical bottlenecks that urgently need to be overcome. First, the precision and uniformity of the feeding system directly affect product yield. Conventional gravity dripping or mechanical pushing methods easily lead to uneven resin distribution, resulting in product thickness deviations exceeding ±0.1mm, which is insufficient to meet the precision manufacturing requirements of optical devices and other applications. Second, the efficiency and quality of the curing process are at odds. Traditional thermosetting equipment uses a single heat source, resulting in a curing cycle of 4-6 hours. Furthermore, the concentrated thermal stress during curing leads to a product deformation rate as high as 3%-5%, severely impacting the yield.

[0003] In terms of environmental control, traditional open-type processing equipment has three major drawbacks: First, temperature and humidity fluctuations exceeding ±5℃ cause changes in resin viscosity, leading to abnormal leveling; second, the dust particle pollution rate in the working environment reaches 0.2mg / m³. 3 This leads to an increase in the surface defect rate of products; thirdly, fluctuations in processing parameters between different batches result in internal stress differences of up to 20%, making it difficult to achieve process standardization. In addition, traditional equipment lacks an automated cleaning system, and resin curing residue needs to be manually removed, with each cleaning taking more than 30 minutes and posing a risk of damaging the mold.

[0004] Existing equipment also suffers from significant limitations in mold compatibility. Traditional three-axis positioning systems have a positioning accuracy of only 0.1mm, which cannot meet the processing requirements of precision molds for micro medical devices. Furthermore, when switching between molds of different sizes, manual adjustments to the mechanical structure are required, resulting in a changeover time of up to 2 hours. Regarding curing process control, traditional equipment can only achieve single-parameter temperature adjustment, failing to address the matching issue between resin curing shrinkage and photoinitiation efficiency. This leads to fluctuations in product transmittance of 8%–12%. Therefore, this project was developed to address these issues in depth. Utility Model Content

[0019] Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Those skilled in the art should connect all electrical components and their compatible power supplies in this case via wires. Appropriate controllers and encoders should be selected according to the actual situation to meet control requirements. The specific connection and control sequence should refer to the working principle described below, where the electrical components are connected in sequence. The detailed connection methods are well-known in the art. The following mainly introduces the working principle and process, and will not describe the electrical control further.

[0021] Example

[0022] like Figure 1-3 As shown, the packaged sealing box 2 is mounted on the concave processing table 1. The stable feeding structure and the curing structure are installed on the packaged sealing box 2. The stable feeding structure includes: a raw material box 3, a hydraulic electric push rod 4, a hydraulic L-shaped tube 5, a hydraulic extrusion plate 6, a feeding guide pipe, a pair of horizontal lead screw modules 7, a horizontal moving block 8, a toothed feeding pipe 9, multiple J-shaped siphon suction pipes 10, a pair of horizontal correction lead screw modules 11, a horizontal correction limit plate 12, two pairs of lifting electric push rods 13, a horizontal scraper, a grinder, a cleaning box 14, and an ultrasonic vibrator.

[0023] Specifically, the raw material box 3 is installed on the packaged sealed box 2, the hydraulic L-shaped pipe 5 is connected to the raw material box 3, the hydraulic electric push rod 4 is installed on the inner side of the hydraulic L-shaped pipe 5, the hydraulic extrusion plate 6 is installed on the pushing end of the hydraulic electric push rod 4, a pair of horizontal lead screw modules 7 are installed parallel to each other on the packaged sealed box 2, the horizontal moving block 8 is installed on the moving end of the pair of horizontal lead screw modules 7, the toothed feeding pipe 9 is installed on the horizontal moving block 8, and the feeding guide pipe is connected to the raw material box 3 and the toothed feeding pipe 9. Multiple of the... J-shaped siphon suction pipes 10 are evenly installed on the toothed feed pipes 9. A pair of horizontal correction screw modules 11 are installed in parallel on the packaged sealing box 2. The horizontal correction limiting plate 12 is installed on the moving end of the pair of horizontal correction screw modules 11. Two pairs of lifting electric push rods 13 are installed in parallel on the horizontal correction limiting plate 12. The horizontal scraper and the grinder are respectively installed on the pushing end of the two pairs of lifting electric push rods 13. The cleaning box 14 is installed inside the concave processing table 1. The ultrasonic vibrator is installed inside the cleaning box 14.

[0024] It should be noted that, as described above, the sealed box 2 is mounted on the concave processing table 1. The extension and retraction of the hydraulic electric push rod 4 inside the hydraulic L-shaped tube 5 drives the hydraulic extrusion plate 6 on its pushing end. This causes the hydraulic extrusion plate 6 to rise and fall stably along the inner side of the hydraulic L-shaped tube 5, thereby extruding the hydraulic pressure inside the hydraulic L-shaped tube 5 into the inner side of the raw material box 3. The rising and falling of the hydraulic electric push rod 4 then guides the hydraulic pressure inside the raw material box 3 to the inner side of the feeding pipe. The feeding pipe then guides the hydraulic pressure to the inner side of the toothed feeding pipe 9. A pair of horizontal screw modules 7 operate, driving the horizontal moving block 8 on them. The horizontal moving block 8 then drives the toothed feeding pipe 9 to move horizontally. The material is pushed upwards, and through the hydraulic and siphon principle, the hydraulic fluid inside the toothed feed tube 9 is diverted to the inside of the J-shaped siphon suction tube 10. The raw material is evenly siphoned onto the mold inside the concave processing table 1 through multiple J-shaped siphon suction tubes 10. A pair of horizontal correction screw modules 11 are operated, which drives the horizontal correction limit block on it. The horizontal correction limit block drives the two pairs of lifting electric push rods 13 on it. The two pairs of lifting electric push rods 13 drive the horizontal scraper and the polisher on it to perform stable horizontal adjustment. Through the horizontal extension and vertical lifting of the horizontal scraper, the raw material liquid on the mold is horizontally scraped and leveled. Similarly, the polisher polishes the cured composite resin.

[0025] like Figure 1-3As shown, the curing structure includes: a pair of curing electric push rods 15, a curing lifting plate 16, multiple curing lamps 17, a pressure box, a pressure extrusion electric push rod, a pressure extrusion plate, a pressure valve, multiple electric heating rods, and two pairs of cooling fans.

[0026] Specifically, a pair of curing electric push rods 15 are installed in parallel on the inner side of the sealed housing 2, the curing lifting plate 16 is installed on the pushing end of the pair of curing electric push rods 15, a plurality of curing lamps 17 are evenly installed on the curing lifting plate 16, the pressure box is installed on the sealed housing 2, the pressure valve is connected to the pressure box and the sealed housing 2, the pressure extrusion electric push rod is installed on the inner side of the pressure box, the pressure extrusion plate is installed on the pushing end of the pressure extrusion electric push rod, a plurality of electric heating rods are evenly installed on the curing lifting plate 16, and two pairs of cooling fans are evenly installed on the curing lifting plate 16.

[0027] It should be noted that, as described above, the extension and retraction of a pair of curing electric push rods 15 drives the curing lifting plate 16 on them to move up and down stably. The curing lifting plate 16 drives multiple curing lamps 17 on it to perform photothermal curing on the composite resin. The extension and retraction of the pressure squeezing electric push rod on the inside of the pressure box drives the pressure squeezing plate on it, causing the pressure squeezing plate to move up and down, thereby diverting the air pressure inside the pressure box to the inside of the set sealing box 2, thereby changing the pressure inside the set sealing box 2. Through the cooperation of multiple electric heating rods and cooling fans, the air pressure between the set sealing box 2 and the concave processing table 1 is changed.

[0028] As a preferred option, the feeding and diversion pipe is further equipped with a sealing valve.

[0029] As a preferred option, the sealed housing 2 is further provided with a pair of hydraulic sealing doors.

[0030] As a preferred embodiment, a temperature sensor is further provided on the inside of the sealed housing 2.

[0031] As a preferred option, a pressure sensor is further provided on the inside of the sealed housing 2.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
