Description

Technical Field

[0001] The present invention relates to a nozzle swing mechanism used in a washing machine, and particularly relates to an effect of improving the washing quality when washing a predetermined sheet by reciprocating the nozzle by a transmission mechanism and setting an optimal washing time.

Background Art

[0002] Due to the progress of science and technology in recent years, everyday electronic products and devices such as smartphones, tablet PCs, and notebook computers have been widely used, and as a result, the development of industries related to semiconductors and circuit boards has been promoted. Since there are a large number of types of chemicals used in the production of the semiconductors and circuit boards, chemical agents and solvents tend to remain relatively on the semiconductor sheets. These agents and solvents not only pollute the environment but also affect the yield of the semiconductors and circuit boards.

[0003] Currently, in the process of washing the semiconductors and circuit boards, a large number of water injection nozzles are often required to wash the semiconductors and circuit boards. Moreover, it is easy for non-washable angles to occur in the nozzles with fixed positions. In addition, conventional washing machines cannot arbitrarily customize the washing process and time according to changes in the types and sizes of semiconductors and circuit boards. The above has become a point that urgently requires research and improvement for those skilled in the art.

Summary of the Invention

Problems to be Solved by the Invention

[0004] Therefore, the inventor collected relevant data regarding the above problems and drawbacks, evaluated and considered them from various aspects, and as a result of continuous trial and modification based on the many years of experience accumulated in the industry, invented a nozzle swing mechanism used in a washing machine.

Means for Solving the Problems

[0005] The main object of the present invention is to provide a nozzle oscillation mechanism used in the above-described washing machine. The nozzle oscillation mechanism includes a base, a conveying device, a washing device, and an air knife assembly. The base includes a washing area and a draining area in that order. The conveying device has a supply unit provided on the washing area side for conveying a predetermined sheet and a discharge unit located on the draining area side. The conveying device also has a plurality of conveying rollers operated by a power unit. The washing device is provided within the washing area. Furthermore, the interlocking device of the washing device has a plurality of nozzles connected to it and a plurality of connection parts located above the conveying device. At least one side of the upper connection parts is provided with an assembly mechanism. One side of the assembly mechanism has a protruding engagement part that is assembled to a transmission mechanism that provides reciprocating movement. The air knife assembly is provided within the draining area. The air knife assembly has a plurality of air knives provided above the conveying device. The reciprocating movement of the nozzle described above allows for multiple cleanings of the same portion of the predetermined sheet, thereby enabling multiple cleanings of the predetermined sheet with a small number of nozzles and reducing the costs associated with using a large number of nozzles.

[0006] A secondary objective of the present invention is as follows: Each of the conveying rollers in the conveying device has a conveying section for conveying the predetermined sheet. Furthermore, each conveying section is provided with a rotating section on both sides. The power unit is engaged with the rotating section of at least one of the conveying rollers via at least one first shaft column to control the reciprocating rotation of the conveying roller. At least two second roller shafts are assembled to the rotating section on the side of each conveying roller that is separated from the power unit, for rotating each other. The reciprocating displacement of the conveying rollers in the conveying device achieves the objective of enabling multiple washes of the same part of the predetermined sheet.

[0007] Another objective of the present invention is as follows: The air knife assembly is provided with a storage space for accommodating pressurized gas supplied from a pre-installed air pressurizing device. Furthermore, a flow straightening plate is provided inside the air knife to obstruct the flow of the gas and equalize the discharge of the gas. In addition, each air knife has an air knife head extending downward, having an air knife opening. Furthermore, at least one fastening member is inserted into the air knife head. By combining the uniform adjustment of the airflow by the flow straightening plate with the tightening of the fastening member, the amount of air discharged from the air knife opening is adjusted, thereby achieving optimal water drainage performance.

[Modes for carrying out the invention]

[0009] Refer to Figures 1-5 and 8 and 9, which show a front view, side view, three-view drawing of the transmission mechanism, three-view drawing of the connecting device, three-view drawing of the interlocking device, a plan cross-sectional view of the nozzle oscillation mechanism, and three-view drawing of the air knife used in the washing machine of the present invention. The nozzle oscillation mechanism used in the washing machine of the present invention mainly includes a base 1, a conveying device 2, a washing device 3, and an air knife assembly 4. The connection relationships of these components are as follows.

[0010] The base 1 includes a washing area 11 and a draining area 12 in that order. The base 1 is also provided with a conveying device 2 that performs reciprocating conveyance. The conveying device 2 has a supply unit 21 located on the washing area 11 side and a discharge unit 22 located on the draining area 12 side. The conveying device 2 also has a plurality of conveying rollers 24 that are operated by a power unit 23.

[0011] The cleaning device 3 is provided within the cleaning area 11. Furthermore, the interlocking device 31 of the cleaning device 3 has multiple nozzles 32 connected to it, and also has multiple connection parts 311 located above the conveying device 2. Furthermore, the upper connecting portion 311 is provided with an assembly mechanism 312 on at least one side. The assembly mechanism 312 has a shielding plate 3121 to which the connecting portion 311 is connected. The shielding plate 3121 has a main body 3122 protruding from a side different from the connecting portion. On one side of the main body 3122, there is a protruding engaging portion 3123 which is assembled to the transmission mechanism 34 via a connecting device 33. The connecting device 33 has a plurality of protrusions 331 which engage with each of the engaging portions 3123, and can be fixed to the engaging portions 3123 by a screw member 3124. Moreover, the ceiling portion of the connecting device 33 is bent so that a top plate 332 located above the transmission mechanism 34 is extended. The transmission mechanism 34 described above has a transmission connecting portion 341 which is assembled to the connecting device 33.

[0012] In addition, to clean from above and below, a plurality of nozzles 32 are also provided on the lower side of the aforementioned conveying device 2.

[0013] The air knife assembly 4 is provided within the drainage area 12. Furthermore, the air knife assembly 4 has a plurality of air knives 41 provided on the upper side of the conveying device 2. Inside each air knife 41 there is a storage space 410 for storing pressurized gas supplied from a pre-installed air pressurizing device (not shown). In addition, a flow straightening plate 42 is provided inside each air knife 41 to obstruct the flow of the gas and make the discharge of the gas uniform. Furthermore, each air knife 41 has an air knife head 411 extending downward, having an air knife opening 4110. In addition, at least one fastening member 43 is inserted into each air knife head 411.

[0014] Each of the transport rollers 24 in the transport device 2 described above has a transport section 241 for transporting a predetermined sheet 5 (e.g., semiconductor, circuit board, etc.). Furthermore, each of the transport sections 241 is provided with a rotating section 242 on both sides. In addition, at least two first roller shafts 25 are provided between the power unit 23 and the transport rollers 24. Each of the first roller shafts 25 has a first shaft column 251 connected to the power unit 23 and at least one rotating section 242. Furthermore, a first connecting member 252 (e.g., a belt, etc.) is provided between each of the first roller shafts 25 to rotate them relative to each other. Furthermore, at least two second roller shafts 26 are assembled to each of the rotating sections 242 on the side of each transport roller 24 that is separated from the power unit 23. Furthermore, each of the second roller shafts 26 rotates relative to each other by at least one second connecting member 261 (e.g., a belt, etc.). Furthermore, the aforementioned power device 23 may be a motor.

[0015] In addition, sensing devices 35 for detecting the oscillation direction of the assembly mechanism 312 are provided on both sides of the assembly mechanism 312, and the sensing devices 35 control the forward and backward pushing effect of the transmission mechanism 34.

[0016] In addition, the aforementioned transmission mechanism 34 may be an air cylinder, a hydraulic cylinder, or a push link combining pneumatic, hydraulic, and electric functions. It should be noted in advance that such simple and equivalent changes and modifications will not thereby limit the scope of protection of the present invention.

[0017] Refer to Figures 1, 2, 6, and 7, which are a front view, a side view, a schematic diagram before nozzle movement, and a schematic diagram after nozzle movement of the nozzle oscillation mechanism used in the cleaning machine of the present invention. As is clear from the drawings, when the present invention is actually applied, first, the predetermined sheet 5 is brought in from the supply section 21 of the conveying device 2. The predetermined sheet 5 is moved toward the discharge section 22 by the conveying rollers 24. When the predetermined sheet 5 is conveyed into the cleaning area 11, the nozzle 32 of the cleaning device 3 discharges a cleaning liquid pressurized by a pre-installed pump (not shown) that is connected to it. As a result, the nozzle 32 cleans the predetermined sheet 5 at high pressure. In addition, the nozzles 32 located on the upper side of the conveying device 2 are pushed back and forth by the transmission mechanism 34, performing multiple high-pressure cleanings on the predetermined sheet 5 as it moves. Furthermore, the nozzles 32 that move back and forth can clean dirt at a wider angle. Then, when the predetermined sheet 5 reaches the discharge side of the cleaning area 11, the conveyor rollers 24 each rotate in opposite directions due to the rotation of the power unit 23, moving the predetermined sheet 5 toward the supply unit 21. This allows the cleaning device 3 to continue the cleaning operation. Then, when the predetermined sheet 5 reaches the input side of the cleaning area 11, the conveyor rollers 24 each rotate in opposite directions due to the rotation of the power unit 23, moving the predetermined sheet 5 toward the discharge unit 22 again. This achieves the objective of repeatedly cleaning the dirt attached to the predetermined sheet 5. In this way, the objective of performing multiple cleanings on the predetermined sheet 5 with a small number of nozzles 32 can be achieved, and the cost of installing a large number of nozzles 32 can be reduced. Furthermore, by setting the transmission frequency of the transmission mechanism 34 and the reciprocating speed per minute of the power unit 23, the optimal cleaning time can be set.

[0018] Furthermore, after the washing of the predetermined sheet 5 is completed, the predetermined sheet 5 enters the drainage area 12. Then, the air knife 41 of the air knife assembly 4 blows the gas pressurized by the pre-installed air pressurizing device onto the surface of the predetermined sheet 5, thereby removing the cleaning liquid adhering to the predetermined sheet 5. Further, the flow rectifying plate 42 provided inside the air knife 41 obstructs the gas blown into the accommodation space 410 after being pressurized by the pre-installed air pressurizing device, and enables the gas to flow along the surface of the flow rectifying plate 42. Thereby, without directly releasing the pressure inside the gas, after equalizing the pressure of the gas at this location, the gas is caused to flow out and be discharged along the gap between the flow rectifying plate 42 and the inner wall of the air knife 41, thereby achieving the effect of uniformly discharging the gas. Also, regarding the air knife head 411 portion, by adjusting the loosening of the fastening member 43, the size of the air knife opening 4110 can be adjusted. Thereby, the effect of controlling the magnitude of the air blowing from the air knife 41 is achieved. Further, the predetermined sheet 5 that has received the blowing of the air knife 41 is carried into the discharge portion 22 along the conveying roller 24 and collected. Thus, by adjusting the magnitude of the air volume, the purpose of controlling the air blowing and draining efficiency according to the material of each predetermined sheet 5 is achieved.

[0019] Also, referring again to FIG. 8 which is a plan sectional view of the nozzle swing mechanism used in the cleaning machine according to the present invention. As is clear from the drawing, in the present invention, the predetermined sheet 5 is conveyed by the conveying roller 24 of the conveying device 2. Each of the conveying rollers 24 is connected to an adjacent conveying roller 24 via the second roller shaft 26 assembled to the rotating portions 242 on both sides and rotates it. Further, in a preferred embodiment of the present invention, in order to achieve the purpose of conveying more of the predetermined sheets 5 simultaneously, the conveying rollers 24 may be connected to each other via an assembly member 27 and arranged in parallel.

[0020] In addition, the above-mentioned nozzle can set the spray range as required. Moreover, the transmission mechanism of the cleaning device can further set the forward and backward pushing distances and the number of reciprocating swings per minute. Furthermore, the number of nozzles to be mounted and the distance between them can also be set.

[0021] In addition, the detailed operating principle of the swing of the nozzle is as follows. When the spray range of the nozzle 32 is set to 400 mm and the distance by which the nozzle 32 is pushed back and forth in cooperation with the transmission mechanism 34 is 25 mm each time, the total spray range of the nozzle 32 becomes 450 mm. Also, the transmission mechanism 34 can reciprocate 60 times per minute (adjustable). And the number of the nozzles 32 is eight, and each interval is 50 mm. On the other hand, each of the lower conveying rollers 24 can convey 25 mm back and forth and can reciprocate 10 times per minute, and the conveying speed is 2 m / min. Also, the length of the predetermined sheet 5 to be conveyed is set to 500 mm. On the premise of the above, the scheduled cleaning time is set to 30 seconds. Since the predetermined sheet 5 takes 15 seconds from entry to discharge, the cleaning time of the predetermined sheet 5 is 15 seconds, the nozzle 32 reciprocates 15 times, and the conveying roller 24 reciprocates 2.5 times. Since the interval between the nozzles 32 is 50 mm, after reciprocation, it just reaches the positions before and after each of the nozzles 32. The cleaning of the same position is performed by three nozzles. Therefore, the number of cleaning times at the same position is (the number of reciprocations of the nozzle 32 × 2) × (the number of reciprocations of the conveying roller 24 × 2). That is, the number of cleaning times at the same position is (15 × 2) × (2.5 × 2) = 30 × 5 = 150, and 150+(the number of cleaning times of the eight nozzles 32, which is 8)=158 times. Therefore, it takes 30 seconds to clean the predetermined sheet 5 158 times at the same position.

[0022] On the other hand, in the process of performing normal cleaning and without the nozzles 32 and the conveying rollers 24 reciprocating, when cleaning the predetermined sheet 5 for 30 seconds at the same position, only 8 cleanings can be performed.

[0023] The present invention is primarily characterized by the fact that, by combining the reciprocating movement of the nozzle 32 in the cleaning device 3 with the reciprocating displacement of the conveying roller 24 in the conveying device 2, the same part of the predetermined sheet 5 is cleaned multiple times, thereby achieving the effect of cleaning the predetermined sheet 5 multiple times with a small number of nozzles 32. Furthermore, a secondary feature is that the amount of air discharged from the air knife opening 4110 is adjusted by combining the uniform adjustment of the airflow rate by the rectifier plate 42 in the air knife 41 with the tightening of the fastening member 43.

[0024] The above are merely preferred embodiments of the present invention, and the scope of the present invention is not limited thereto. Therefore, it should be noted in advance that any simple modifications and equivalent structural changes made using the contents of the specification and drawings of the present invention are all included within the scope of the present invention for the same reasons.

[0025] In summary, the nozzle oscillation mechanism used in the cleaning machine of the present invention can reliably achieve its intended effect and purpose when actually applied. Therefore, the present invention is indeed a highly practical research and development project and meets the requirements for filing an invention patent; therefore, we will file the application in accordance with the law. In order to protect the inventor's research and development and creative efforts, we hope that the examiner will grant this patent application promptly. If the examiner has any doubts, please inform us in writing, and the inventor will cooperate to the best of his ability. [Explanation of symbols]
