Description

Technical Field

[0001] This utility model relates to a power supply thermal conductive silicone potting device, and in particular to a power supply thermal conductive silicone potting device used in the field of drive power supply processing. Background Technology

[0002] LED driver power supplies are power conversion devices that convert input electrical energy (usually AC) into specific voltage and current forms, providing a stable and suitable power supply for electronic devices (such as LED lamps). Their core consists of rectifier circuits, control chips, transformers / inductors, and protection circuits, and are key supporting components of electronic devices.

[0003] The core functions of an LED driver power supply are: voltage / current adaptation and stable output (converting AC to DC and adjusting output parameters through a control chip to ensure that the load device operates within the rated current and voltage range, avoiding performance abnormalities caused by overload or undervoltage) and multiple safety protections (integrating overvoltage, overcurrent, short circuit, open circuit and other protection circuits to prevent equipment damage due to abnormal operating conditions).

[0004] When manufacturing LED driver power supplies, personnel use thermally conductive silicone potting equipment to encapsulate them. However, existing thermally conductive silicone potting equipment has difficulty cleaning and recycling the silicone that overflows from the LED driver power supply during the encapsulation process, which reduces the cleanliness of the LED driver power supply and wastes the encapsulation material. Utility Model Content

[0005] The technical problem to be solved by this utility model is that existing power thermal conductive silicone potting devices have difficulty cleaning and recycling the glue overflowing from the LED driver power supply during the glue injection process, which reduces the cleanliness of the LED driver power supply and causes waste of glue injection materials.

[0006] To solve the above problems, this utility model provides a power thermal conductive silicone potting device, including a base, a vertical tube fixedly connected to the upper end of the base, a pair of threaded rings threadedly connected to the outer end of the vertical tube, a lifting ring rotatably connected between the pair of threaded rings, a circular groove opened at the outer end of the lifting ring, a plug-in bracket movably inserted into the circular groove, an injection tube fixedly connected inside the plug-in bracket, a bent tube fixedly connected to the outer end of the vertical tube, a mounting cap fixedly connected to the end of the bent tube away from the vertical tube, a collection tube threadedly connected to the end of the mounting cap away from the bent tube, a feed head fixedly connected to the end of the collection tube away from the mounting cap, and a filter tube threadedly connected to the end of the feed head away from the collection tube.

[0007] In the aforementioned power thermal conductive silicone potting device, it can not only recycle the overflowing glue and reduce the amount of glue waste, but also filter the recycled glue to improve its cleanliness and ensure the glue injection effect.

[0008] As a further improvement of this application, the inner wall of the lifting ring is rotatably connected to the outer end of the vertical tube, and there is a gap between the lower end of the glue injection tube and the upper end of the base.

[0009] As a further improvement of this application, a circular groove is provided at the end of each pair of threaded rings that are close to each other, and a rubber ring is fixedly connected inside the circular groove.

[0010] As a further improvement of this application, the side end of the rubber ring is flush with the side end of the threaded ring, and the rubber ring is rotatably connected to the lifting ring.

[0011] As a further improvement of this application, a pair of limiting blocks are fixedly connected to the inner wall of the lifting ring, and a pair of limiting grooves that are slidably connected to the limiting blocks are opened at the outer end of the vertical tube.

[0012] As another improvement of this application, a movable block is fixedly connected to one end of the plug-in bracket near the lifting ring. An adjustment groove is provided at the outer end of the movable block. A miniature electric push rod is fixedly connected to the inner wall of the adjustment groove. An installation block is fixedly connected to the telescopic end of the miniature electric push rod. A docking groove is provided inside the lifting ring to rotatably connect with the movable block. Multiple installation grooves are provided on the inner wall of the docking groove to be movably inserted into the installation block.

[0013] As a further improvement to this application, multiple mounting slots are arranged in a ring within the mating slot, the mating slots are connected to the circular slot, and the diameter of the mating slot is larger than the diameter of the circular slot.

[0014] 1. During the glue injection process, the lifting ring and all its mechanisms can move together on the vertical pipe to adjust the height of the glue injection tube. This device is convenient for use when injecting glue into items of different thicknesses and heights. After glue injection, if glue overflow occurs, the bending tube can be moved according to the overflow location to adjust the position of the filter tube. Then, the extraction pump in the collection tube is started to draw the glue into the collection tube through the filter tube and the feed head, thereby collecting the overflowing glue for the next use. When extracting the glue, the filter tube can filter out foreign matter in the glue. When this application is used, it can not only recover the overflowing glue and reduce the amount of glue waste, but also filter the recovered glue to improve its cleanliness and ensure the glue injection effect.

[0015] 2. During the glue injection process, the plug-in frame can be rotated to adjust the angle of the glue injection tube, thus facilitating glue injection operations from multiple angles. When the plug-in frame rotates, it will drive the moving block to rotate within the mating groove. After adjusting the angle of the glue injection tube, the micro electric push rod is activated, causing its telescopic end to push the mounting block out of the adjustment groove and into the corresponding mounting groove to limit the plug-in frame and fix the glue injection tube at the adjusted angle.

[0023] The two embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0024] First implementation method:

[0025] Figure 1-4A power-conducting thermal silicone potting device is shown, including a base 1. A vertical tube 2 is fixedly connected to the upper end of the base 1. A pair of threaded rings 3 are threadedly connected to the outer end of the vertical tube 2. The same lifting ring 4 is rotatably connected between the pair of threaded rings 3. A circular groove is opened at the outer end of the lifting ring 4. A plug-in bracket 5 is movably inserted into the circular groove. A glue injection tube 6 is fixedly connected to the inside of the plug-in bracket 5. A bent tube 7 is fixedly connected to the outer end of the vertical tube 2. A mounting cover 8 is fixedly connected to the end of the bent tube 7 away from the vertical tube 2. A collection tube 9 is threadedly connected to the end of the mounting cover 8 away from the bent tube 7. A pump is fixedly connected to the inside of the collection tube 9. A feed head 10 is fixedly connected to the end of the collection tube 9 away from the mounting cover 8. A filter tube 11 is threadedly connected to the end of the feed head 10 away from the collection tube 9.

[0026] The inner wall of the lifting ring 4 is rotatably connected to the outer end of the vertical tube 2. There is a gap between the lower end of the glue injection tube 6 and the upper end of the base 1. A pair of threaded rings 3 are provided with a circular groove at their close ends. A rubber ring 12 is fixedly connected inside the circular groove. The side end of the rubber ring 12 is flush with the side end of the threaded ring 3. The rubber ring 12 is rotatably connected to the lifting ring 4.

[0027] A pair of limiting blocks 13 are fixedly connected to the inner wall of the lifting ring 4. A pair of limiting grooves 14 that are slidably connected to the limiting blocks 13 are opened at the outer end of the vertical tube 2. The limiting blocks 13 can limit the lifting ring 4 and prevent it from rotating when it moves up and down.

[0028] The application is used in the following steps:

[0029] Step 1: When using, place the item to be processed on the base 1, so that the position of the item to be glued is directly below the glue injection tube 6, and then use the glue injection tube 6 to inject glue into the item.

[0030] Step 2: During the glue injection process, the operator can rotate a pair of threaded rings 3 according to the thickness and height of the item to be processed, so that it pushes the lifting ring 4 and all the mechanisms on it to move up or down on the vertical tube 2 together, thereby adjusting the height of the glue injection tube 6. This device is convenient for use when injecting glue into items of different thicknesses and heights.

[0031] Step 3: If glue overflow occurs after glue injection, the bending tube 7 can be moved according to the location of the overflow, and its angle and position can be adjusted. Then, the position of the filter tube 11 can be adjusted until the filter tube 11 comes into contact with the glue. After that, the extraction pump in the collection tube 9 is started to draw the glue through the filter tube 11 and the feed head 10 into the collection tube 9, so as to collect the overflowing glue for the next use, thereby reducing the amount of glue wasted.

[0032] When drawing up the glue, the filter tube 11 can filter out foreign matter in the glue to improve the cleanliness of the glue.

[0033] In summary, when used, this application can not only recycle overflowing glue, reducing glue waste, but also filter the recycled glue to improve its cleanliness and ensure the glue application effect.

[0034] Second implementation method:

[0035] This embodiment adds the following structure based on the first embodiment, while the rest remains the same as the first embodiment, as detailed below:

[0036] Figure 5 The connector 5 is shown to be fixedly connected to a movable block 15 near the lifting ring 4. The outer end of the movable block 15 is provided with an adjustment groove. A miniature electric push rod 16 is fixedly connected to the inner wall of the adjustment groove. An installation block 17 is fixedly connected to the telescopic end of the miniature electric push rod 16. The inside of the lifting ring 4 is provided with a docking groove that is rotatably connected to the movable block 15. The inner wall of the docking groove is provided with multiple installation grooves that are movably inserted into the installation block 17.

[0037] Multiple mounting slots are arranged in a ring within the mating slot, and the mating slot communicates with the circular slot. The diameter of the mating slot is larger than the diameter of the circular slot.

[0038] During the glue injection process, the plug-in frame 5 can be rotated to adjust the angle of the glue injection tube 6, thereby facilitating glue injection operations from multiple angles. When the plug-in frame 5 rotates, it will drive the moving block 15 to rotate within the mating groove. After adjusting the angle of the glue injection tube 6, the micro electric push rod 16 is activated, causing its telescopic end to push the mounting block 17 out of the adjustment groove and into the corresponding mounting groove, thereby limiting the plug-in frame 5 and fixing the glue injection tube 6 at the adjusted angle.

[0039] In light of current practical needs, the above-described embodiments adopted in this application are not limited to these. Any changes made within the scope of knowledge possessed by those skilled in the art without departing from the concept of this application still fall within the protection scope of this utility model.
