Description

Technical Field

[0001] This utility model relates to the field of dispensing machines, specifically to a UV dispensing machine. Background Technology

[0002] A dispensing machine is a device used for spraying coatings onto the surface of parts. When spraying coatings onto parts, a dispensing machine is used to treat the surface of the parts. It is also called a glue applicator, dripping machine, glue applicator, or potting machine. It is specifically designed to control fluids, dripping or coating fluids onto the surface or interior of a product. A UV dispensing machine uses a dispensing valve to precisely apply liquid adhesive to the product surface and uses ultraviolet light to cure it quickly, thereby achieving functions such as component fixation, sealing, heat conduction, or protection.

[0003] Existing automatic dispensing machines mainly consist of four parts: an adhesive supply system, a motion control system, a dispensing valve, and a control system. The control system operates the dispensing machine by using air pressure or a mechanical pump to drive the adhesive from the glue tank through pipelines to the dispensing valve. Commonly used adhesive types include epoxy resin, silicone, and UV adhesive. The valve needle is pneumatically or electrically controlled to open and close, and the adhesive is extruded from the nozzle using air pressure or mechanical pressure to form a preset dispensing pattern.

[0004] However, although existing UV dispensing machines can meet the curing needs of most flat or simple structure products, there are still some shortcomings. Existing curing systems usually use a top vertical irradiation method. When there are protrusions, grooves, slits or stepped structures on the side of the product, the ultraviolet rays are blocked due to the straight-line propagation characteristics, resulting in shadow curing blind areas on the side walls, bottom surface or internal structure, which affects the curing effect of the product. In order to compensate for the insufficient curing of the shadow areas, it is necessary to extend the irradiation time or increase the power of the light source, but this will cause the adhesive layer on the product surface to overheat, affecting the dispensing quality and stable use. Utility Model Content

[0005] The purpose of this invention is to address the above-mentioned deficiencies by providing a UV dispensing machine to solve the technical problem in the background art where the curing effect of existing dispensing machines is poor, affecting the quality and stability of product dispensing and curing.

[0006] The objective of this utility model is achieved through the following means:

[0007] A UV dispensing machine includes a cabinet and a cover mounted on the cabinet. A worktable is mounted on the cabinet, and a dispensing device is mounted on the worktable. The dispensing device includes a base, a support frame mounted on the base, and a dispensing gun. A movable slide is mounted on the base, and a mounting fixture is connected to the movable slide. A movable module is connected to the support frame, and the movable module is connected to the dispensing gun via a lifting assembly, allowing the dispensing gun to move towards the mounting fixture for dispensing via the lifting assembly. A curing mechanism for photocuring the dispensed product is connected to the base. The curing mechanism includes a protective cover, a first curing lamp, and a second curing lamp housed within the protective cover. A curing cavity is formed inside the protective cover. One end of the movable slide extends into the curing cavity. The first curing lamp is mounted within the curing cavity via a rotating rod. One end of the rotating rod extends outward from the protective cover and is connected to a driving component. The driving component drives the rotating rod to tilt and adjust the first curing lamp. The second curing lamp is mounted inside the curing cavity.

[0008] Furthermore, as described above, the movable slide is provided in two sets, and the adjacent ends of the two sets of movable slides extend into the interior of the curing cavity. The movable slides are detachably connected to the mounting fixture via sliding seats.

[0009] By setting up two sets of movable slides extending into the curing cavity and using detachable mounting fixtures, the position of the product in the curing cavity can be flexibly adjusted, so that different areas of the product can enter the effective irradiation range of the curing lamp. At the same time, the two sets of movable slides form a dual-station setup, and the detachable sliding seat design facilitates quick fixture replacement to adapt to the curing needs of different products.

[0010] Furthermore, as described above, a connecting bracket is formed inside the protective cover, and a bearing seat is provided on the connecting bracket. The rotating rod passes through the bearing seat and is connected to the first curing lamp. The axial direction of the rotating rod extends along the length direction of the base, so that the rotation of the rotating rod can drive the first curing lamp to tilt forward / backward.

[0011] The tilt angle adjustment function of the first curing lamp is achieved through the structural design of the bearing housing and rotating rod. This design can change the illumination angle of the curing lamp, and for complex parts such as protrusions, grooves or stepped structures on the side of the product, the tilt direction of the light can be adjusted to effectively cover the shadow area, avoiding the curing blind spot problem caused by traditional vertical illumination, and ensuring the curing effect.

[0012] Furthermore, as described above, one end of the rotating rod passes through a protective cover and is connected to a driving component, which is composed of a drive motor.

[0013] The structure, employing a drive motor to directly drive the rotating rod, allows for precise control of the tilt angle and adjustment speed of the first curing lamp, achieving automated adjustment. This design improves the ease of operation and curing efficiency while ensuring the stability of the light source angle adjustment, avoiding errors caused by manual adjustment, and further guaranteeing curing quality.

[0014] Furthermore, as described above, the second curing lamp comprises two sets, and the two sets of second curing lamps are arranged opposite each other inside the curing cavity.

[0015] Two sets of second curing lamps are symmetrically arranged inside the curing cavity to form a multi-light source irradiation system. This layout can irradiate and cure the product from different directions, especially for slits, bottom surfaces, or shadowed areas of internal structures. By using complementary irradiation from multiple light sources, curing blind spots are eliminated, curing defects caused by the linear propagation characteristics of a single light source are reduced, and overall curing efficiency is improved.

[0016] Furthermore, the protective cover has heat dissipation holes at its top, and a fan is connected to the top of the protective cover. A heat dissipation cover is also provided on the top of the protective cover.

[0017] The protective cover integrates heat dissipation holes, a fan, and a heat sink to form a forced cooling system. This design effectively dissipates the heat generated during the curing process, preventing overheating of the adhesive layer on the product surface due to prolonged exposure to high-power light. It also protects the stable operation of internal components such as the curing lamp, improving the equipment's continuous operation capability and lifespan.

[0018] The beneficial effects of this invention are as follows: The first curing lamp achieves tilt angle adjustment through the cooperation of a rotating rod and a driving component, which can flexibly adjust the irradiation direction and effectively cover the shadow area of ​​the product's side wall. The driving component drives the rotating rod to rotate and adjust the first curing lamp, allowing it to perform multi-angle light curing on the dispensing product. The second curing lamp is fixedly installed inside the curing cavity to form multi-angle supplementary irradiation, which solves the problem of curing blind spots caused by the linear propagation characteristics of ultraviolet rays in complex structure products. At the same time, it reduces the direct effect on the originally blocked areas, eliminating the need to compensate for the curing effect by extending the irradiation time or increasing the light source power. This ensures the curing quality after dispensing and avoids the problem of overheating of the adhesive layer on the product surface due to excessive irradiation, thereby enhancing the curing effect and efficiency.

The rotating rod 145 passes through the bearing seat 148 and is connected to the first curing lamp 142. The axial direction of the rotating rod 145 extends along the length direction of the base 3, so that the rotation of the rotating rod 145 can drive the first curing lamp 142 to tilt forward / backward.

[0030] The tilt angle adjustment function of the first curing lamp 142 is achieved through the structural design of the bearing seat 148 and the rotating rod 145. This design can change the illumination angle of the curing lamp. For complex parts such as protrusions, grooves or stepped structures on the side of the product, the tilt direction of the light can be adjusted to effectively cover the shadow area, avoiding the curing blind spot problem caused by traditional vertical illumination and ensuring the curing effect.

[0031] In this embodiment, the first curing lamp 142 and the second curing lamp 143 are composed of ultraviolet (UV) lamps.

[0034] The second curing lamp 143 includes two sets, and the two sets of second curing lamps 143 are arranged opposite to each other inside the curing cavity 144.

[0035] Two sets of second curing lamps 143 are symmetrically arranged inside the curing cavity 144 to form a multi-source irradiation system. This layout can irradiate and cure the product from different directions, especially for slits, bottom surfaces, or shadowed areas of internal structures. By using complementary irradiation from multiple light sources, curing blind spots are eliminated, curing defects caused by the linear propagation characteristics of a single light source are reduced, and overall curing efficiency is improved.

[0038] In this embodiment, the integrated design of the dispensing device and the curing mechanism 14 on the base 3, combined with the flexible adjustment of the movable slide 6 and the mounting fixture 7, enables the equipment to adapt to products of different sizes and shapes.

[0039] The specific usage process in this embodiment is as follows:

[0040] The product is mounted on the sliding seat 10 of the movable slide table 6 using the mounting fixture 7. The dispensing gun 5 is connected to an external glue supply device. The movement of the movable slide table 6 and the movable module 8 is controlled by the controller, allowing the dispensing gun 5 to dispense glue onto the product on the mounting fixture 7. After dispensing, the movable slide table 6 drives the mounting fixture 7 to move the product into the curing cavity 144. The first curing lamp 142 then cures the glued product by light. A drive motor can drive a rotating rod 145 to rotate the first curing lamp 142 forward / backward, allowing the first curing lamp 142 to be tilted at an adjustable angle, effectively covering the shaded area of ​​the product's sidewall during curing. The drive component 146... The drive rod 145 rotates and adjusts the first curing lamp 142, allowing it to cure the dispensing product from multiple angles. The second curing lamp 143 is fixedly installed inside the curing cavity 144, forming multi-angle supplementary irradiation.
