Description

A glue curing device Technical Field

[0001] This utility model belongs to the field of adhesive curing technology, and specifically relates to an adhesive curing device. Background Technology

[0002] Currently available adhesive curing devices are generally divided into two types: one is an automatic UV lamp curing system after coating, and the other is a manual UV lamp curing system. However, regardless of the curing method, the adhesive surface is not smooth but rather viscous. In this state, the adhesive is prone to attracting dust and moisture during laser use, which can lead to the adhesive burning out and becoming ineffective. Summary of the Invention

[0003] In view of this, the purpose of this utility model is to provide an adhesive curing device to solve the problem that the adhesive is not smooth due to the easy adsorption of dust and moisture during the existing adhesive curing process.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] An adhesive curing device includes a protective cover, a UV light source, and a vacuum assembly. The UV light source is mounted on the protective cover via a movable support member, with one end of the movable support member containing the UV light source extending into the protective cover. The vacuum assembly is mounted on the protective cover and communicates with the inside of the protective cover. A sealing strip is provided along the circumferential side of the bottom of the protective cover.

[0006] In one possible implementation, the protective shield is made of a transparent material.

[0007] In one possible implementation, the vacuum assembly includes a vacuum pump, the suction end of which is connected to the inside of the protective cover.

[0008] In a possible implementation, the movable support member can move on the protective cover along a first direction, which is either the transverse or longitudinal direction of the top surface of the protective cover;

[0009] The protective cover has a movable hole extending in a second direction parallel to the first direction. A sealing baffle is rotatably fitted on the outer side of the part of the movable support member that passes through the protective cover, and the sealing baffle is attached to the top surface of the protective cover.

[0010] In one possible implementation, the top of the protective cover is provided with a guide rail arranged along a first direction, and the bottom of the movable support member is provided with a slider that slides in cooperation with the guide rail.

[0011] In one possible implementation, the movable support member includes a support frame connected to a UV light source via a height adjustment assembly;

[0012] The height adjustment assembly includes a telescopic arm, a mounting base, and an adjustment sleeve. The two ends of the telescopic arm are respectively connected to a support frame and a mounting base. The UV light source is mounted on the mounting base. The mounting base has a cylindrical connecting part that extends axially towards the movable support member. The outer surface of the cylindrical connecting part has an external thread. An adjustment sleeve is also provided on the outer side of the cylindrical connecting part. One end of the adjustment sleeve is rotatably connected to the telescopic arm, and the other end is threadedly engaged with the external thread of the cylindrical connecting part.

[0013] In one possible implementation, the bottom of the sealing strip is provided with a positioning groove for embedding optical fibers.

[0014] In one possible implementation, the movable support member is an L-shaped structure, comprising a vertical end and a cantilever end, the vertical end being connected to a protective cover, and a UV light source being mounted on the cantilever end.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] This utility model's adhesive curing device, by placing a UV light source and a vacuum assembly on a protective cover, allows the protective cover to be directly attached to the cold plate at the dispensing location when adhesive needs to be cured. The protective cover forms a closed space through a sealing strip, and the vacuum assembly creates a vacuum inside, thus allowing the adhesive to be cured under vacuum. This results in a smooth adhesive surface, making it less prone to attracting dust and moisture, and increasing the reliability and lifespan of the laser.

[0017] Moreover, the UV light source can be moved on the protective cover, which makes it easier to adjust the irradiation position more accurately or flexibly as needed, making it more practical. Attached Figure Description

Detailed Implementation

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to specific embodiments.

[0027] Please refer to Figures 1-7. An embodiment of this application provides an adhesive curing device, including a protective cover 1, a UV light source 3, and a vacuum assembly. The UV light source 3 is provided on the protective cover 1 through a movable support member 2. One end of the movable support member 2 with the UV light source 3 passes into the protective cover 1. The vacuum assembly is provided on the protective cover 1 and communicates with the inside of the protective cover 1. A sealing strip 4 is provided on the bottom of the protective cover 1 along the circumferential side.

[0028] The protective cover 1 serves as a barrier and provides protection. By integrating the UV light source 3 and the vacuum assembly onto the protective cover 1, it can move as a single unit. This allows the protective cover 1 to be directly placed over the adhesive 8 for curing, making the process convenient, quick, and efficient. The UV power source is mounted on the protective cover 1 via a movable support member 2, which facilitates the adjustment of the UV light source 3's position, enabling more accurate irradiation or irradiation according to different needs. The vacuum assembly is connected to the interior of the protective cover 1 and is used to extract air from inside the protective cover 1, creating a vacuum environment. Sealing strips 4 are provided on the circumferential sides of the bottom of the protective cover 1 for sealing. When the protective cover 1 is placed on a flat surface, a seal is formed, isolating the interior of the protective cover 1 from the outside and effectively maintaining the vacuum environment.

[0029] Through the above technical solution, the UV light source 3 and the vacuum assembly are set on the protective cover 1. When the glue 8 needs to be cured, the protective cover 1 can be directly attached to the cold plate 6 at the glue dispensing position. The protective cover 1 can form a closed space through the sealing strip 4, and the vacuum assembly can make the inside reach a vacuum state. In this way, the glue 8 can be cured in a vacuum state, thereby making the surface of the glue 8 smooth and making it less likely to attract dust and moisture, which increases the reliability and service life of the laser.

[0030] In one embodiment, the protective cover 1 is made of a transparent material.

[0031] In this way, the protective cover 1 made of transparent material can make it easy for the operator to see the inside of the protective cover 1, and thus make curing more convenient and accurate. The transparent material can be glass or acrylic, and there are no restrictions.

[0032] Furthermore, the vacuum assembly includes a vacuum pump 7, the suction end of which is connected to the inside of the protective cover 1.

[0033] In this way, the air inside the protective cover 1 can be extracted by the vacuum pump 7, thus creating a vacuum environment inside the sealed protective cover 1.

[0034] In order to enable the UV light source 3 to adjust the irradiation position in the horizontal direction, further, as shown in Figure 7, the movable support member 2 can move along a first direction on the protective cover 1, the first direction being the horizontal or vertical direction of the top surface of the protective cover 1; the protective cover 1 is provided with a movable hole (which is blocked in the figure) extending along a second direction parallel to the first direction, and a sealing baffle 12 is rotatably fitted on the outer side of the part of the movable support member 2 that enters the protective cover 1, the sealing baffle 12 abutting against the top surface of the protective cover 1.

[0035] In this way, while the movable support member 2 can move along the movable hole in the second direction, it can achieve a good seal with the sealing baffle 12, which helps to create a vacuum environment inside the protective cover 1. Furthermore, because the protective cover 1 is under negative pressure, the sealing baffle 12 can also fit tightly against the top surface of the protective cover 1 under the pressure of external atmospheric pressure. This ensures that the sealing baffle 12 can provide a good seal while moving with the movable support member 2. In a specific implementation, an annular guide flange 11 can also be provided on the outer side of the sealing baffle 12 on the protective cover. The guide flange 11 forms a guide groove, the length of which is greater than the length of the sealing baffle 12. This facilitates better movement of the movable support member 2 and the sealing baffle 12.

[0036] In specific implementation, the top of the protective cover 1 is provided with a guide rail 13 arranged along a first direction, and the bottom of the movable support member 2 is provided with a slider that slides in cooperation with the guide rail. The guide rail 13 allows the movable support member 2 to slide smoothly on the top of the protective cover 1, facilitating its movement. The slider is preferably T-shaped, and the groove on the guide rail is also correspondingly configured as a T-shaped groove, making the sliding structure more stable and reliable.

[0037] To achieve height adjustment of the UV light source 3, as shown in Figures 5 and 6, the movable support member 2 includes a support frame 22, which is connected to the UV light source 3 via a height adjustment assembly 21. The height adjustment assembly 21 includes a telescopic arm 211, a mounting base 212, and an adjustment sleeve 213. The two ends of the telescopic arm 211 are connected to the support frame and the mounting base 212, respectively. The UV light source 3 is mounted on the mounting base 212. The mounting base 212 has a cylindrical connecting part 214 extending axially towards the movable support member 2. The outer surface of the cylindrical connecting part 214 has an external thread, and the outer side of the cylindrical connecting part 214 is also provided with an adjustment sleeve 213. One end of the adjustment sleeve 213 is rotatably connected to the telescopic arm 211, and the other end is threadedly engaged with the external thread of the cylindrical connecting part 214.

[0038] The support frame 22 is connected to the UV light source 3 via a height adjustment assembly 21. The UV light source 3 is specifically mounted on a mounting base 212, which is connected to the support frame 22 via a telescopic arm 211. The telescopic arm 211 can extend and retract axially but cannot rotate. The top of the mounting base 212 has an integrally formed upwardly extending cylindrical connecting part 214. The outer wall of the cylindrical connecting part 214 is provided with external threads, which engage with the outer adjusting sleeve 213. The upper end of the adjusting sleeve 213 is rotatably connected to the upper end of the telescopic arm 211 via a bearing, and the lower end of the adjusting sleeve 213 is threadedly engaged with the outer wall of the cylindrical connecting part 214. Thus, when the adjusting sleeve 213 rotates, it can drive the mounting base 212 on which the UV light source 3 is mounted to move up and down, thereby realizing the height adjustment of the UV light source 3.

[0039] To further improve the sealing performance between the sealing strip 4 and the optical fiber 5, a positioning groove 41 for embedding the optical fiber 5 is provided at the bottom of the sealing strip 4. The positioning groove 41 is a semi-circular or arc-shaped groove, which can better reduce the gap when the sealing strip 4 presses down on the optical fiber 5 compared to not having a positioning groove 41.

[0040] In the specific implementation, the movable support member 2 has an L-shaped structure, including a vertical end and a cantilever end. The vertical end is connected to the protective cover 1, and a UV light source 3 is installed on the cantilever end.

[0041] Specifically, in order to facilitate the formation of a seal, a sliding sealing ring can be provided between the adjusting sleeve 213 and the sealing baffle 12, and a sliding sealing element can also be provided between the sealing baffle 12 and the protective cover 1.

[0042] The method of using the adhesive curing device according to an embodiment of this application is as follows:

[0043] First, after applying adhesive to the optical fiber 5 at the dispensing position on the cold plate 6, the adhesive 8 is cured. The protective cover 1 is then placed on the cold plate 6 at the dispensing position, forming a closed space with the cold plate 6. Then, the pneumatic vacuum pump 7 extracts the air from the closed space to create a vacuum. The position of the UV lamp is then adjusted according to the location requirements, and the UV lamp is turned on so that the UV light spot 9 covers the adhesive 8 for irradiation. This allows the adhesive 8 to cure. After curing in a vacuum, the surface of the adhesive 8 is smooth and does not easily attract dust and moisture, increasing the reliability and service life of the adhesive 8.

[0044] The above are merely preferred embodiments of this utility model. It should be noted that the above preferred embodiments should not be considered as limitations on this utility model, and the scope of protection of this utility model should be determined by the scope defined in the claims. For those skilled in the art, several improvements and modifications can be made without departing from the spirit and scope of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model.
