Description

Technical Field

[0001] This utility model relates to the field of UV dispensing machines, and in particular to a UV curing component for dispensing LED lamps. Background Technology

[0002] In the manufacturing process of LED lighting fixtures, the dispensing process is a crucial step in achieving component fixation, sealing, and optical performance optimization. UV curing technology, due to its advantages such as fast curing speed and low energy consumption, is widely used for curing the adhesive after dispensing. However, existing UV-curable components used for dispensing in LED lighting fixtures generally suffer from the following technical defects:

[0003] Currently, to optimize the equipment, processing methods, and procedures for UV adhesive dispensing, and to increase production capacity and reduce the defect rate, ultraviolet lamps are often added to UV dispensing machines. This involves using ultraviolet lamps to cure the product after UV adhesive dispensing. However, existing UV curing methods have a limited light coverage area, which can easily lead to incomplete or over-curing of the adhesive in certain areas. Therefore, we propose a UV curing component for LED lighting dispensing. Utility Model Content

[0004] To address the technical problem of limited coverage of curing light from light sources, this invention provides a UV curing component for LED lamp dispensing.

[0005] This utility model is achieved by the following technical solution: a UV curing component for dispensing adhesive in LED lamps, including a workbench, a support frame fixedly connected above the workbench surface, a multi-directional adjustment component fixedly connected above the support frame, and a dispensing UV curing component connected to the multi-directional adjustment component.

[0006] The multi-directional adjustment assembly includes a connecting platform, which is fixedly connected to the top of the support frame. A working motor is fixedly connected to the connecting platform, and a connecting screw is connected to the output end of the working motor. The connecting screw is rotatably mounted on the connecting platform, and a movable seat is threadedly connected to the surface of the connecting screw. A movable platform is fixedly connected to the bottom of the movable seat, and a movable frame is slidably connected to the bottom of the movable platform. The movable frame is mounted on the top of the connecting platform.

[0007] A receiving platform is fixedly connected to the outside of the movable base. A drive motor is installed above the receiving platform. The output end of the drive motor is connected to a drive screw. The drive screw is rotatably mounted on the receiving platform. The mounting platform is threaded onto the surface of the drive screw. A limit rod passes through the inside of the mounting platform. Both ends of the limit rod are fixed to the receiving platform.

[0008] The adhesive dispensing and UV curing assembly includes a mounting platform, on which a motor is fixedly mounted. The output end of the motor is connected to a drive rod, and the bottom end of the drive rod is connected to a main planetary gear. A sub-planetary gear meshes with the outer side of the main planetary gear, and a gear ring meshes with the outer side of the sub-planetary gear. An adhesive dispenser is connected below the main planetary gear, and an ultraviolet lamp is fixedly connected below the sub-planetary gear. The mounting platform and the gear ring are fixed together by a connecting rod.

[0009] The motor drives the main planetary gear to rotate slowly via a drive rod. The main planetary gear meshes with three sets of sub-planetary gears, causing the sub-planetary gears to both rotate on their own axis and revolve around the central ring. The dispensing nozzle below the main planetary gear rotates synchronously with the central shaft, dispensing adhesive to the LED lights. Ultraviolet lamps below the sub-planetary gears are arranged in a 120-degree circle, creating 360-degree three-dimensional lighting coverage as the planetary gears move. During dispensing, the ultraviolet lamps are simultaneously activated, dynamically tracking and curing the freshly extruded adhesive to prevent the lighting range from deviating from the dispensing area.

[0010] As a further optimization of this utility model, the multi-directional adjustment component is fixed above the support frame via a connecting platform. The working motor drives the connecting screw to rotate, causing the moving seat to move along the screw axis. The sliding connection structure between the moving platform and the moving frame enables the dispensing and photocuring component to be adjusted back and forth in the horizontal direction.

[0011] As a further optimization of this utility model, the drive motor on the receiving platform drives the drive screw to rotate, causing the mounting platform to move up and down along the limit rod, thereby realizing the height adjustment of the ultraviolet lamp and the dispensing device and adapting to LED lamps of different sizes.

[0012] As a further optimization of this utility model, a three-legged bracket is rotatably connected to the drive rod, and the three fulcrums of the three-legged bracket are rotatably connected to sub-planetary gears. There are three sets of sub-planetary gears, and the three sets of sub-planetary gears are arranged around the gear ring at equal angles.

[0013] As a further optimization of this invention, when the main planetary gear rotates, the sub-planetary gear rotates on its own axis and revolves around the gear ring, driving the ultraviolet lamp to perform a combined motion. This allows the colloid on the surface of the LED lamp to receive ultraviolet light irradiation from different angles, eliminating the irradiation blind spots of traditional fixed light sources. At the same time, the constant speed characteristic of the gear transmission ensures uniform light intensity, avoiding localized over-curing or under-curing.

[0014] As a further optimization of this utility model, a protective sleeve for protecting the planetary gear assembly is installed on the surface of the gear ring. The protective sleeve on the surface of the gear ring can isolate the planetary gear assembly from the external environment and prevent glue from splashing into the transmission mechanism during the dispensing process, thus affecting the operating accuracy of the equipment.

[0015] As a further optimization of this utility model, a pluggable glue tube is connected to the outside of the dispensing device body. When it is necessary to replenish glue to the dispensing device, the glue tube is inserted into the dispensing device to inject glue.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] 1. This invention utilizes three sets of planetary gears to drive ultraviolet lamps distributed at 120-degree intervals. The combined rotation and revolution of the planetary gears ensures that the LED lamp's adhesive application area receives 360-degree three-dimensional ultraviolet light irradiation, eliminating the blind spots of traditional fixed light sources. The constant speed characteristic of the gear transmission ensures uniform light intensity, preventing incomplete or over-curing of the adhesive in certain areas, and significantly improving product yield.

[0018] 2. This utility model's multi-directional adjustment component, through the coordinated action of the working motor and the drive motor, enables precise adjustment of the dispensing and curing assembly in both the horizontal (front-back, left-right) and vertical (height) directions. This adapts to the dispensing and curing distance requirements of LED lamps of different sizes, solving the problem of poor compatibility caused by the fixed position of the light source in traditional equipment.

[0019] 3. This utility model effectively isolates the planetary gear assembly from glue splashes by the protective sleeve on the surface of the gear ring, reducing wear on transmission components and extending the service life of the equipment. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0028] Example 1:

[0029] Please combine Figures 1-5 This embodiment proposes a UV curing assembly for LED lamp dispensing, including a workbench 1, a support frame 2 fixedly connected above the workbench 1, a multi-directional adjustment assembly 3 fixedly connected above the support frame 2, and a dispensing UV curing assembly 4 connected to the multi-directional adjustment assembly 3.

[0030] The multi-directional adjustment assembly 3 includes a connecting platform 31, which is fixedly connected to the top of the support frame 2. A working motor 32 is fixedly connected to the connecting platform 31. A connecting screw 33 is connected to the output end of the working motor 32. The connecting screw 33 is rotatably mounted on the connecting platform 31. A movable seat 35 is threadedly connected to the surface of the connecting screw 33. A movable platform 36 is fixedly connected to the bottom of the movable seat 35. A movable frame 37 is slidably connected to the bottom of the movable platform 36. The movable frame 37 is mounted above the connecting platform 31.

[0031] A receiving platform 38 is fixedly connected to the outer side of the movable base 35. A drive motor 39 is installed above the receiving platform 38. A drive screw 310 is connected to the output end of the drive motor 39. The drive screw 310 is rotatably mounted on the receiving platform 38. The mounting platform 41 is threaded onto the surface of the drive screw 310. A limit rod 311 passes through the inner side of the mounting platform 41. Both ends of the limit rod 311 are fixed on the receiving platform 38.

[0032] In the specific technical solution, the multi-directional adjustment component 3 is fixed above the support frame 2 via the connecting platform 31. The working motor 32 drives the connecting screw 33 to rotate, causing the moving seat 35 to move along the screw axis. The sliding connection structure between the moving platform 36 and the moving frame 37 enables the horizontal adjustment of the dispensing and UV curing component 4. Simultaneously, the drive motor 39 on the receiving platform 38 drives the drive screw 310 to rotate, causing the mounting platform 41 to move up and down along the limiting rod 311, thereby achieving height adjustment of the UV lamp 49 and the dispensing device 48 to accommodate LED lamps of different sizes.

[0033] The dispensing and UV curing assembly 4 includes a mounting platform 41, on which a motor 42 is fixedly mounted. The output end of the motor 42 is connected to a drive rod 43, and the bottom end of the drive rod 43 is connected to a main planetary gear 44. A sub-planetary gear 45 meshes with the outer side of the main planetary gear 44, and a gear ring 46 meshes with the outer side of the sub-planetary gear 45. A dispensing device 48 is connected below the main planetary gear 44, and an ultraviolet lamp 49 is fixedly connected below the sub-planetary gear 45. The mounting platform 41 and the gear ring 46 are fixed together by a connecting rod 410.

[0034] There are three sets of sub-planetary gears 45, which are arranged at equal angles of 120 degrees inside the gear ring 46. A three-legged bracket 47 is rotatably connected to the drive rod 43, and the three fulcrums of the three-legged bracket 47 are rotatably connected to the sub-planetary gears 45.

[0035] More specifically, the motor 42 drives the main planetary gear 44 to rotate slowly via the drive rod 43. The main planetary gear 44 meshes with three sets of sub-planetary gears 45, causing the sub-planetary gears 45 to both rotate on their own axis and revolve around the central axis within the gear ring 46. The dispensing nozzle 48 below the main planetary gear 44 rotates synchronously with the central axis to dispense adhesive to the LED lights. Ultraviolet lamps 49 below the sub-planetary gears 45 are arranged in a 120-degree circle, forming a 360-degree three-dimensional light coverage as the planetary gears move. During the dispensing process, the ultraviolet lamps 49 are turned on simultaneously to dynamically track and cure the freshly extruded adhesive, preventing the light range from deviating from the dispensing area.

[0036] A further advanced technical solution involves the sub-planetary gear 45 rotating on its own axis and simultaneously revolving around the gear ring 46 when the main planetary gear 44 rotates. This combined motion drives the ultraviolet lamp 49, allowing the colloid on the LED lamp surface to receive ultraviolet light irradiation from different angles, eliminating the irradiation blind spots of traditional fixed light sources. Simultaneously, the constant speed characteristic of the gear transmission ensures uniform light intensity, preventing localized over-curing or under-curing.

[0037] A protective sleeve 5 is installed on the surface of the gear ring 46 to protect the planetary gear assembly. The protective sleeve 5 on the surface of the gear ring 46 isolates the planetary gear assembly from the external environment, preventing glue from splashing into the transmission mechanism during dispensing and affecting the operating accuracy of the equipment. A pluggable dispensing tube 6 is connected to the outside of the dispensing unit 48. When it is necessary to replenish the glue in the dispensing unit 48, the glue is dispensed by inserting the dispensing tube 6 into the dispensing unit 48.

[0038] Working principle:

[0039] Spatial positioning of multi-directional adjustment components

[0040] The multi-directional adjustment component 3 is fixed above the support frame 2 via the connecting platform 31. The working motor 32 drives the connecting screw 33 to rotate, causing the moving seat 35 to move along the screw axis. The sliding connection structure between the moving platform 36 and the moving frame 37 enables the horizontal adjustment of the dispensing UV curing component 4. At the same time, the drive motor 39 on the receiving platform 38 drives the drive screw 310 to rotate, causing the mounting platform 41 to move up and down along the limiting rod 311, thereby adjusting the height of the UV lamp 49 and the dispensing device 48 to accommodate LED lamps of different sizes.

[0041] Synergistic operation of dispensing and curing

[0042] Motor 42 drives main planetary gear 44 to rotate slowly via drive rod 43. Main planetary gear 44 meshes with three sets of sub-planetary gears 45, causing the sub-planetary gears 45 to both rotate on their own axis and revolve within gear ring 46. Dispenser 48 below main planetary gear 44 rotates synchronously with the central shaft to dispense adhesive to LED lights. Ultraviolet lamps 49 below sub-planetary gears 45 are arranged in a 120-degree circle, forming a 360-degree three-dimensional light coverage as the planetary gears move. During dispensing, ultraviolet lamps 49 are turned on synchronously to dynamically track and cure the freshly extruded adhesive, preventing the light range from deviating from the dispensing area. When it is necessary to replenish adhesive to dispenser 48, the dispensing tube 6 is inserted into dispenser 48 for dispensing.

[0043] Optimization of illumination uniformity in planetary gear transmission

[0044] When the main planetary gear 44 rotates, the sub-planetary gear 45 rotates on its own axis and revolves around the gear ring 46, driving the ultraviolet lamp 49 to perform a combined motion. This allows the colloid on the surface of the LED lamp to be irradiated with ultraviolet light from different angles, eliminating the irradiation blind spots of traditional fixed light sources. At the same time, the constant speed characteristic of the gear transmission ensures uniform light intensity and avoids local over-curing or under-curing.

[0045] Protective design

[0046] The protective sleeve 5 on the surface of the gear ring 46 can isolate the planetary gear assembly from the external environment and prevent glue from splashing into the transmission mechanism during the dispensing process, thus affecting the operating accuracy of the equipment.

[0047] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
