Description

Technical Field

[0001] The utility model relates to the technical field of ultraviolet light curing, in particular to an ultraviolet light curing testing device. Background Art

[0002] Photocurable resin contains active and photosensitive initiators, which can be initiated under ultraviolet light to generate three-dimensional cross-linked high-strength and high-modulus polymer materials. Photocurable resin is a thermosetting resin that can chemically react and cross-link and cure in a short period of time after being exposed to light.

[0003] The existing UV curing test method is as follows: during the test, the height of the light source from the surface sample is input, the light source power required for curing is switched to, the infrared probe is aligned with the center of the curing box, the UV radiation flux probe is placed in the center of the curing box, the UV light source is turned on, and after the data on the external display of the UV radiation flux probe is stable, the sample to be cured, which is fixed in advance on the pull-out table, is pushed into the curing box. The sample is cured and releases heat, and the external display data of the infrared temperature probe is automatically output on the display. When the temperature peak appears, the light source is turned off, and the sample is cured for half an hour after cooling. The sample is taken out, and the Barcol hardness of the inner and outer surfaces of the sample is tested with a Barcol hardness tester, and the data is input into a table, and the entire test data is output together, saved and printed out.

[0004] The defect of the above test method is that the sample cooling step must be carried out in the curing box, which makes it impossible to continuously test in the curing box, seriously affecting the test effect. If multiple curing boxes are configured at the same time, the equipment cost will be too high. Utility Model Content

[0023] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be understood that the specific implementation methods described here are only used to explain the utility model and do not limit the protection scope of the utility model.

[0024] It should be noted that when an element is referred to as being "fixed to", "disposed on", "fixed on" or "installed on" another element, it may be directly on the other element or there may be a central element. When an element is considered to be "connected to" another element, it may be directly connected to the other element or there may be a central element at the same time. Further, when an element is considered to be "fixedly connected to" another element, the two may be fixed in a detachable connection manner or in a non-detachable connection manner, such as socketing, snap-on, one-piece fixation, welding, etc., which can be achieved in the prior art and will not be repeated here. When an element is perpendicular or approximately perpendicular to another element, it means that the ideal state of the two is vertical, but due to the influence of manufacturing and assembly, there may be a certain vertical error. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0026] The “first” and “second” involved in the present invention do not represent specific quantities and orders, but are merely used to distinguish names.

[0027] Combined with Figure 1-3 A UV curing test device of the present embodiment includes a circular curing box 1, on which a plurality of curing chambers 2 are evenly distributed along the circumferential direction thereof, each curing chamber 2 is matched with a chamber door, and two adjacent curing chambers 2 are separated by a partition 3, and a circular track 4 is further provided in the curing box 1, and the circular track 4 is coaxially arranged with the curing box 1, and the circular track 4 passes through a plurality of curing chambers 2 and is located at the upper end of the curing chamber 2, and a slider 5 is slidably connected to the circular track 4, and the circular track 4 and the slider 5 are electric slide rails, and an UV light source 6 is provided on the slider 5, and the UV light source 6 emits UV light downward to achieve the effect of UV curing, and an opening is provided on the partition 3 to allow the slider 5 to pass through, so as to ensure that the slider 5 can smoothly pass through the partition 3 with the UV light source 6.

[0028] The UV curing test device can continuously perform multiple groups of UV curing tests, with high test efficiency, saving a lot of waiting time, and all curing chambers 2 share the same light curing structure, with low equipment cost and no need to configure multiple curing boxes.

[0029] As a preferred solution of the utility model, a split rubber sealing sheet 7 is provided at the opening, and the middle of the rubber sealing sheet 7 is cut open to form a split structure. When the slider 5 passes by, the two sides of the rubber sealing sheet 7 can be pushed open. After the slider 5 passes, the rubber sealing sheet 7 is reset under the driving force of its own elastic force to achieve sealing.

[0030] As a preferred solution of the utility model, a lifting structure 8 for controlling the up and down movement of the ultraviolet light source 6 is provided on the slider 5, so that the height of the light source from the sample surface can be controlled according to the test requirements. Specifically, the lifting structure 8 includes a hollow rod 81, which is vertically connected to the slider 5; a movable rod 82, one end of which is movably inserted into the hollow rod 81, and the outer diameter of the movable rod 82 matches the inner diameter of the hollow rod 81; a driving member 83, which is used to control the movable rod 82 to move back and forth relative to the hollow rod 81. The hollow rod 81 and the movable rod 82 cooperate to limit the movement direction of the ultraviolet light source 6, ensuring that the ultraviolet light source 6 can only move straight up and down to adjust the distance from the sample surface.

[0031] As a preferred solution of the utility model, the driving member 83 is a motor, and the output shaft of the motor is arranged perpendicular to the hollow rod 81. The output shaft of the motor extends into the hollow rod 81 and is located at the upper end of the movable rod 82. A pulley 84 is connected to the output shaft of the motor, and a pull rope 85 is wound around the pulley 84. One end of the pull rope 85 is connected to the movable rod 82. The movable rod 82 is controlled to move up and down by retracting and releasing the pull rope 85, thereby achieving the purpose of controlling the lifting and lowering of the ultraviolet lamp source 6. Compared with air cylinders and oil cylinders, the structure is simpler and lighter, and there is no need to arrange air and oil circuits.

[0032] As a preferred solution of the utility model, in order to prevent the lifting structure 8 from colliding with the partition 3 and being damaged when passing through the partition 3, a protective cover 9 is provided on the outer side of the lifting structure 8. When the lifting structure 8 is retracted, the lifting structure 8 and the ultraviolet light source 6 are both located in the protective cover 9. The lower end of the protective cover 9 is open to facilitate the extension of the ultraviolet light source 6.

[0033] As a preferred solution of the present invention, a timer is provided on the curing box 1 corresponding to each curing cavity 2, so as to time the curing time and cooling time of each curing cavity 2.

The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
