Description

Technical Field

[0001] This utility model relates to the field of fluorescent chip sorting technology, specifically a precision feeding guide groove for fluorescent chip sorting. Background Technology

[0002] Phosphor chips are a new type of optoelectronic component, which usually refers to devices that integrate and encapsulate fluorescent materials with micro LED chips in the form of thin films or sheets. Their core function is to excite the fluorescent materials with blue or ultraviolet light emitted by the LED chip, thereby mixing to produce the desired white light or other specific colors of light. They are key components for realizing high color gamut and high brightness micro white LEDs. After production, phosphor chips need to be sorted and fall to the designated position through a feeding guide.

[0003] Existing feeding guides often use pure gravity slides or vibratory feeders. Since the phosphor chips themselves have very little weight, the static friction between them and the guide wall, air resistance, etc., become the main influencing factors. This makes it easy for the phosphor chips to stop midway, have unstable sliding posture, and get stuck with multiple chips overlapping. It is impossible to achieve accurate, orderly, and reliable feeding to the next station. Summary of the Invention

[0004] In view of this, the present invention provides a precision feeding guide groove for sorting fluorescent chip wafers, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a precision feeding guide for sorting fluorescent chip wafers, comprising a support, an air suction mechanism fixedly connected to the top of the support, a protective net fixedly connected to the upper inner side of the air suction mechanism, a guide mechanism fixedly connected to the top of the air suction mechanism, the guide mechanism comprising a perforated plate fixedly connected to the top of the air suction mechanism, the perforated plate having through holes inside, and a protective shell fixedly connected to the top of the perforated plate.

[0006] Preferably, the bracket includes a base, the base has a fixing hole inside, and a support rod is fixedly connected to the top of the base.

[0007] Preferably, the suction mechanism includes a housing fixedly connected to the top of the bracket, an air suction shell fixedly connected inside the housing, a shell hole provided at the top of the air suction shell, a suction pump fixedly connected to the lower part of the housing, an exhaust pipe fixedly connected to the lower part of the suction pump, and a suction pipe fixedly connected to the top of the suction pump.

[0008] Preferably, the protective net includes a fixed frame fixedly connected to the upper inner side of the air intake mechanism, and a net body is fixedly connected to the inner side of the fixed frame.

[0009] Preferably, the through holes are arranged perpendicular to the horizontal plane, and the distance between adjacent through holes is less than the minimum width of the phosphor chip.

[0010] Preferably, the diameter of the through hole gradually increases from top to bottom.

[0011] By employing the above technical solution, the precision feeding guide groove for sorting fluorescent chip wafers of this utility model has at least the following beneficial effects: Compared with the prior art, the present invention has the following beneficial effects: This invention, by setting up an air suction mechanism and a guiding mechanism, facilitates precise and smooth material dropping. Activating the air suction mechanism generates a negative pressure airflow from top to bottom in the through hole, allowing the phosphor chip to glide stably under the influence of the downward force of gravity and the vertical downward adsorption force. Furthermore, since the diameter of the through hole gradually increases from top to bottom, it ensures that the phosphor chip does not move too fast at the end of the glide, preventing it from deviating from the dropping position due to inertia, thereby achieving precise material dropping.

[0014] Reference Figure 1-4This utility model provides a precision feeding guide for sorting fluorescent chip, including a support 1. An air suction mechanism 2 is fixedly connected to the top of the support 1. A protective net 3 is fixedly connected to the upper inner side of the air suction mechanism 2. A guide mechanism 4 is fixedly connected to the top of the air suction mechanism 2. The guide mechanism 4 includes a perforated plate 401 fixedly connected to the top of the air suction mechanism 2. The perforated plate 401 has through holes 402 for air passage. A protective shell 403 is fixedly connected to the top of the perforated plate 401. During use, a vacuum pump 204 is activated, allowing air from the shell 201 to enter the suction shell 202 through multiple shell holes 203. The air is then discharged from the exhaust pipe 206 through the suction pipe 205. This creates a downward negative pressure airflow in the through holes 402. When the fluorescent chip is placed on the perforated plate 401, it is subjected to downward pressure due to gravity and vertical force. The downward adsorption force allows the phosphor chip to slide down along the perforated plate 401, ensuring it falls smoothly to the dropping position. This adsorption force effectively suppresses random bouncing, drifting, or stalling that might occur due to the chip's light weight, maintaining stable gliding. Furthermore, because the aperture of the through-hole 402 gradually increases from top to bottom, under the same suction negative pressure, a larger aperture allows for greater flow and a stronger adsorption force on the phosphor chip, while a smaller aperture results in a weaker adsorption force. At the top of the perforated plate 401, the adsorption force is smaller, allowing the phosphor chip to start smoothly and initially slide down. As the phosphor chip descends, the adsorption force gradually increases, ensuring that the speed of the phosphor chip does not become too fast at the end of its slide, preventing it from deviating from the dropping position due to inertia, thus achieving precise dropping.

[0015] Furthermore, the bracket 1 includes a base 101, the base 101 has a fixing hole 102 inside, and a support rod 103 is fixedly connected to the top of the base 101. The base 101 can be fixed on the plane through the fixing hole 102.

[0016] Furthermore, the suction mechanism 2 includes a housing 201 fixedly connected to the top of the bracket 1. A suction shell 202 is fixedly connected inside the housing 201. The top of the suction shell 202 is provided with a shell hole 203. A suction pump 204 is fixedly connected to the lower part of the housing 201. An exhaust pipe 206 is fixedly connected to the lower part of the suction pump 204. A suction pipe 205 is fixedly connected to the top of the suction pump 204. The shell holes 203 are evenly distributed on the top of the suction shell 202 to ensure that the air in all parts of the housing 201 can be evenly sucked away, making the air pressure distribution inside the housing 201 more uniform.

[0017] Furthermore, the protective net 3 includes a fixed frame 301 fixedly connected to the upper inner side of the suction mechanism 2. A net body 302 is fixedly connected to the inner side of the fixed frame 301. The protective net 3 has a certain protective function to prevent foreign objects from entering the suction pump 204 and easily causing damage to the suction pump 204.

[0018] Furthermore, the through holes 402 are arranged vertically relative to the horizontal plane. The vertically arranged through holes 402 can generate a vertically downward adsorption force on the phosphor chip. The distance between adjacent through holes 402 is less than the minimum width of the phosphor chip, ensuring that the phosphor chip can contact at least one row of through holes 402, thereby continuously being subjected to the adsorption force.

[0019] Furthermore, the diameter of the through hole 402 gradually increases from top to bottom, so that the adsorption force can gradually increase as the phosphor chip gradually moves downward, ensuring that the phosphor chip does not move too fast at the end of the sliding process.

[0020] Working principle: During use, the air pump 204 is activated, allowing air from the outer casing 201 to enter the suction casing 202 through multiple casing holes 203. The air is then discharged through the suction pipe 205 and the exhaust pipe 206. This creates a downward negative pressure airflow in the through-hole 402. When the phosphor chip is placed onto the perforated plate 401, the downward force of gravity and the vertically downward suction force allow the phosphor chip to slide downwards along the perforated plate 401, ensuring it falls smoothly to the dropping position. Furthermore, the suction force effectively prevents the phosphor chip from becoming too light and potentially causing it to sag. The random jumping, drifting, or stagnation of the phosphor chip prevents it from sliding stably. Because the diameter of the through-hole 402 gradually increases from top to bottom, under the same suction negative pressure, the flow rate through the larger hole is greater, and the adsorption force on the phosphor chip is stronger. Conversely, the adsorption force is smaller. At the top of the through-hole plate 401, the adsorption force is smaller, allowing the phosphor chip to start smoothly and initially slide down. As the phosphor chip gradually slides down, the adsorption force gradually increases, ensuring that the phosphor chip does not move too fast at the end of the slide. This prevents the phosphor chip from deviating from the dropping position due to inertia, thus achieving precise dropping.
