[0001] This invention belongs to the field of LED production line equipment manufacturing technology, specifically a fully automatic ultrasonic cleaning device. Background Technology

[0002] In the mass production of LEDs, a large amount of phosphor adhesive is required for LED encapsulation. Phosphor adhesive provides an encapsulation and protection structure for LED chips, while also improving luminous efficacy and quality. It is an indispensable and important component of LED products.

[0003] During the preparation, storage, and use of LED fluorescent adhesive, various dispensing and storage cups are prone to adhering with residues of fluorescent adhesive and its raw materials. These residues require removal using ultrasound and cleaning agents. While the cleaning process can be performed with ultrasonic equipment, the residues in the cups need to be thoroughly removed through multiple cleaning cycles. The subsequent transfer, relocation, and arrangement of these cleaning processes still require manual labor. For large-scale LED production lines, the workload for cleaning and maintaining these cups is enormous. Traditional cleaning methods are time-consuming, labor-intensive, inefficient, and prone to leaving blind spots with residual residue, which is detrimental to the efficiency of mass production of LED products. Therefore, we provide a fully automated ultrasonic cleaning device to solve these problems. Summary of the Invention

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0027] Example 1

[0028] like Figure 1-5 and Figure 8 As shown, a fully automatic ultrasonic cleaning device includes a housing 1 and a basket assembly 3. The housing 1 has folded edges on all four sides. A cleaning tank 2 is fixedly connected inside the housing 1. The basket assembly 3 is located inside the cleaning tank 2, which contains cleaning fluid. There are three housings 1 and three cleaning tanks 2, so that the same basket assembly 3 can be cleaned three times. The basket assembly 3 includes a basket body 301, which is a centrally symmetrical cylinder. The basket body 301 is provided with multiple cup holders 302 for holding plastic cups. The multiple cup holders 302 are symmetrically distributed along the axis of the basket body 301. Two symmetrical working bearings 303 are installed on the basket body 301. The basket body 301 has toothed grooves 304. The plastic cups to be cleaned can be held onto the basket body 301 by the cup holders 302. When the basket assembly 3 is driven to rotate, the plastic cups can rotate with the basket body 301.

[0029] The cleaning tank 2 is filled with cleaning fluid, and an ultrasonic device is attached to the side wall of the cleaning tank 2. The principle of ultrasonic cleaning is mainly to convert the sound energy of the high-power ultrasonic frequency source into mechanical vibration through the transducer. The ultrasonic waves are radiated into the cleaning fluid in the cleaning tank 2 through the inner wall of the cleaning tank 2. Due to the radiation of the ultrasonic waves, the microbubbles in the liquid in the cleaning tank 2 can maintain vibration under the action of the sound waves, thereby directly and repeatedly impacting the dirt. During the cleaning process, the ultrasonic device is turned on at the same time to ensure that the rotating rubber cup is fully cleaned under the ultrasonic cavitation state of the cleaning fluid.

[0030] In this embodiment, the material basket assembly 3 and the cleaning tank 2 are connected by a snap-fit ​​assembly 4. The snap-fit ​​assembly 4 includes two snap-fit ​​plates 401. The sides of the two snap-fit ​​plates 401 that are far apart from each other are fixedly connected to the two side walls of the cleaning tank 2, and the height of the right snap-fit ​​plate 401 is slightly lower than the height of the left snap-fit ​​plate 401. This allows the material basket assembly 3 to be tilted at a certain angle after it is placed, so that the water inside the material basket assembly 3 and the plastic cup can be drained after the gripping device picks up the material basket assembly 3. The two snap-fit ​​plates 401 are provided with slots 402 inside, and two working bearings 303 are respectively snapped into the inside of the two slots 402. The inner diameter of the slots 402 is adapted to the outer diameter of the working bearings 303.

[0031] Through the installation structure of the material basket assembly 3, the inclined and rotating material basket body 301 allows the cleaning fluid to be repeatedly poured into and poured out of the inner cavity of the plastic cup, so that the inner wall of each plastic cup can be continuously refreshed and cleaned.

[0032] In this embodiment, a drive assembly 5 is provided on the outer shell 1. The drive assembly 5 is used to drive the material basket assembly 3 to rotate. The drive assembly 5 includes a rotating shaft 503 installed inside the cleaning tank 2. The left end of the rotating shaft 503 passes through the left side of the cleaning tank 2 and extends to the outside of the cleaning tank 2. The cleaning tank 2 is provided with a round boss that matches the rotating shaft 503. A bearing that matches the rotating shaft 503 is installed in the round boss, so as to ensure that the rotation of the rotating shaft 503 and the first gear 504 is more stable. The outer surface of the rotating shaft 503 is fixedly connected to the first gear 504 and the second gear 505. The first gear 504 is located inside the cleaning tank 2, and the second gear 505 is located outside the cleaning tank 2. The first gear 504 meshes with the tooth groove 304. After the material basket assembly 3 is placed inside the cleaning tank 2, the teeth on the first gear 504 will be inserted into the tooth groove 304.

[0033] In this embodiment, an mounting plate 501 is installed on the upper surface of the housing 1, a motor 502 is installed on the outer surface of the mounting plate 501, a third gear 506 is fixedly connected to the outer surface of the output end of the motor 502, the output end of the motor 502 passes through the mounting plate 501 and extends to the outside of the mounting plate 501, and the third gear 506 and the second gear 505 are connected by chain drive.

[0034] In this embodiment, the level of the cleaning fluid is lower than the highest point of the basket body 301 and higher than the lowest point of the basket body 301. This allows the cleaning fluid in the cup to drain from the basket body 301 when the cup is installed and rotating. The cup can be repeatedly rinsed by sinking it back below the cleaning fluid level in the basket body 301 when the cup is installed and rotating.

[0035] In this embodiment, when the basket body 301 is tilted, the toothed groove 304 engages with the cup opening of the rubber cup, which is tilted downwards. This allows the tilted basket body 301 to rotate around the rubber cup. Once the rubber cup is removed from the surface of the cleaning liquid, the downward-facing cup can pour out the residual tilted liquid inside its cavity and then be refilled with new cleaning liquid after sinking into the cleaning liquid, thereby promoting the effect of repeated cleaning and rinsing.

[0036] In this embodiment, the cup holder 302 is provided with a U-shaped opening groove. The groove surface of the U-shaped opening groove is adapted to the outer wall of the cup. The cup is fixed by the snap-fit ​​of the U-shaped opening groove, making it easy to quickly install and remove the cup and maintaining the stability of its snap-fit ​​state.

[0037] This embodiment also provides a method for using a fully automatic ultrasonic cleaning device, including the following operating steps:

[0038] S1: The material basket assembly 3 is placed into the frame for automatic feeding. The gripping device automatically grabs the material basket assembly 3 and places it onto the feeding track. The material basket assembly 3 is automatically conveyed to the cleaning position. The gripping device automatically grabs the material basket assembly 3 onto the first cleaning tank 2. After it reaches the position, the safety door closes and automatic cleaning begins. After cleaning, the material basket assembly 3 is automatically grabbed onto the second cleaning tank 2. After it reaches the position, the safety door closes and automatic cleaning begins. After cleaning, the material basket assembly 3 is automatically grabbed onto the third cleaning tank 2. After it reaches the position, the safety door closes and automatic cleaning begins. During the three cleaning processes, the material basket assembly 3 and the glue cups are both arranged at an angle inside the cleaning tank 2. The motor 502 drives the material basket assembly 3 to rotate. The tilted and rotating material basket body 3 allows the cleaning liquid to be repeatedly poured into and poured out of the inner cavity of the glue cups, so that the inner wall of each glue cup is continuously refreshed and cleaned. After cleaning, the material basket assembly 3 is automatically grabbed onto the unloading track. The unloading track automatically conveys the material basket assembly 3 to the unloading position. The gripping device automatically grabs the material basket assembly 3 onto the unloading platform. Cleaning is complete.

[0039] S2: The cleaning solution in the three cylinders is discharged into the high-temperature distillation recovery machine by means of a pump through the pipe below the cleaning cylinder. The distillation recovery machine is started manually. After distillation and condensation, the cleaning solution flows through the pipe into the storage tank for storage.

[0040] The working principle of this embodiment is as follows:

[0041] First, the plastic cup to be cleaned is clamped onto the plastic cup clamp 302. Then, the grabbing device automatically grabs the material basket assembly 3 into the cleaning tank 2. At this time, the two working bearings 303 will be respectively engaged in the two slots 402, and the teeth of the first gear 504 will be inserted into the tooth groove 304. Then, the motor 502 is started, which drives the third gear 506 to rotate. The rotation of the third gear 506 drives the chain and the second gear 505 to rotate. The rotation of the second gear 505 drives the rotating shaft 503 and the first gear 504 to rotate. The first gear 504 rotates... The device can drive the material basket assembly 3 and the material cup to rotate. By rotating the material basket assembly 3 and the material cup and combining it with ultrasonic waves, the material cup can be cleaned automatically. The tilted and rotating material basket assembly 3 allows the cleaning fluid to be repeatedly poured into and poured out of the inner cavity of the material cup, so that the inner wall of each material cup is continuously refreshed and cleaned. This can effectively reduce the workload required for cleaning and maintenance of material cups in mass LED production lines, save cleaning time and manpower and improve work efficiency. At the same time, it can avoid cleaning blind spots and residues, thereby greatly increasing the mass production benefits of LED products.

[0042] Example 2

[0043] The difference between this embodiment and Embodiment 1 is that it can filter out large particulate impurities in the cleaning fluid inside the cleaning tank 2, thereby preventing impurities from clogging the pipes.

[0044] like Figure 2 , Figure 6 and Figure 7 As shown, the cleaning tank 2 is equipped with a filter assembly 6, which is used to filter out large particulate impurities in the cleaning fluid. The filter assembly 6 includes a first filter frame 601, a second filter frame 602, and a cross support plate 603. The outer surface of the cross support plate 603 is fixedly connected to the inner wall of the cleaning tank 2. The bottom surfaces of the first filter frame 601 and the second filter frame 602 are in contact with the upper surface of the cross support plate 603. The first filter frame 601 and the second filter frame 602 are symmetrical about the center point of the cleaning tank 2. The first filter frame 601 has an opening that corresponds to the left side clamping plate 401. The first filter frame 601 has a round hole that matches the first gear 504, and the second filter frame 602 has a second slot that matches the right side plate 401. The cleaning box 2 has two symmetrical slots 604 inside. The outer surfaces of the first filter frame 601 and the second filter frame 602 are fixedly connected to two symmetrical U-shaped plates 605, and one side of the U-shaped plate 605 is inserted into the slot 604. The first filter frame 601 and the second filter frame 602 can be supported by a cross support plate 603.

[0045] In this embodiment, the filter assembly 6 further includes two insert plates 606. The bottom surfaces of the two insert plates 606 are respectively inserted into the interior of the two slots 604, and the two sides of the insert plates 606 respectively contact the sides of the two adjacent U-shaped plates 605 that are close to each other. By setting the insert plates 606, the orientation of the first filter frame 601 and the second filter frame 602 can be limited.

[0046] The working principle of this embodiment is as follows:

[0047] Before cleaning the plastic cup, place the first filter frame 601 on the cross support plate 603 and insert one side of the U-shaped plate 605 on the first filter frame 601 into the slot 604. Then push the first filter frame 601 to the left to its maximum distance, so that the first filter frame 601 contacts the left side wall of the cleaning tank 2. After that, place the second filter frame 602 on the cross support plate 603 and insert one side of the U-shaped plate 605 on the second filter frame 602 into the slot 604. Then push the second filter frame 602 to the right to its maximum distance, so that the first filter frame 601 contacts the left side wall of the cleaning tank 2. The second filter frame 602 contacts the right side wall of the cleaning tank 2. Finally, the bottom surfaces of the two insert plates 606 are respectively inserted into the two slots 604. At this time, the two sides of the insert plates 606 contact the sides of the two adjacent U-shaped plates 605, thereby limiting the first filter frame 601 and the second filter frame 602 in the horizontal direction. At this time, the first filter frame 601 and the second filter frame 602 can filter large particulate impurities in the cleaning liquid, thereby preventing large particulate impurities from clogging the pipes when the cleaning liquid is distilled in the subsequent process.
