[0027] In the description of the present invention, it should be understood that the terms "connected," "connected," "fixed," etc. used in the present invention should be interpreted broadly. For example, the terms may refer to fixed connection, detachable connection, or integration; mechanical connection, welding connection; direct connection, indirect connection through an intermediate medium, internal communication between two elements, or interaction between two elements, unless otherwise explicitly defined. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on specific circumstances.
[0028] like Figures 1 to 4 As shown, a straight trough type flushing device of a preferred embodiment of the utility model includes an upper cover 10 and a lower cover 20. The upper cover 10 and the lower cover 20 cover the interior to form a flushing trough 30. The upper cover 10 and / or the lower cover 20 are provided with a water inlet 11, and the flushing trough 30 is provided with a drain outlet 31. The water inlet 11 is connected with the flushing trough 30 and the drain outlet 31 respectively. The lower cover 20 is provided with a product limiting groove 21 for placing products. The product limiting groove 21 is located in the flushing trough 30 and is connected with the flushing trough 30. The product limiting groove 21 is provided with a product supporting surface 22. The flushing trough 30 is provided with a first side surface 32 and a second side surface 33 on opposite sides of the first direction X, respectively. A first flushing channel 34 is formed between the product supporting surface 22 and the first side surface 32, and a second flushing channel 35 is formed between the product supporting surface 22 and the second side surface 33.
[0029] The straight trough type flushing device of the present invention comprises a flushing box body including an upper cover 10 and a lower cover 20. When the upper cover 10 and the lower cover 20 are closed, a box body is formed. The flushing trough 30 is located inside the upper cover 10 and the lower cover 20. The lower cover 20 is provided with a product limiting groove 21 for placing the product. When the upper cover 10 is opened, the product limiting groove 21 is provided with a product supporting surface 22. The product is placed in the product limiting groove 21 and supported by the product supporting surface 22. The flushing liquid enters the flushing trough 30 from the water inlet 11. After the product is placed in the product limiting groove 21, a first flushing channel 34 and a second flushing channel 35 are formed on both sides of the product in the thickness direction. After the flushing liquid enters the flushing trough 30, the flushing liquid enters the first flushing channel 34 and the second flushing channel 35 respectively, thereby achieving synchronous cleaning of both sides of the product, simplifying operation, and improving cleaning effect.
[0030] As one embodiment, the product to be cleaned is an indium phosphide substrate.
[0031] Further, such as Figure 3 As shown, the height a of the first flushing channel 34 is set at 0.5mm-1mm, the height b of the second flushing channel 35 is set at 0.5mm-1mm, and the width c of the flushing groove 30 is set at 110mm-112mm. After the product is placed in the product limiting groove 21, the first flushing channel 34 is located below the product, and the flushing liquid enters the first flushing channel 34 to flush the lower end surface of the product. The second flushing channel 35 is located above the product, and the liquid enters the second flushing channel 35 to flush the upper end surface of the product. By limiting the width c of the flushing groove 30, the height a of the first flushing channel 34, and the height b of the second flushing channel 35, the flushing space where the product is located is controlled in a relatively narrow state. When the flushing liquid fills the flushing groove 30, under the condition of the same flushing liquid flow rate, the water flow rate can form a larger impact force, thereby improving the cleaning effect of the product.
[0032] Further, such as Figures 1 to 2 As shown, it also includes a bracket 40 and a lifting drive member 41. The lifting drive member 41 is fixed to the bracket 40, and the driving end of the lifting drive member 41 is connected to the upper cover 10. The bracket 40 is used to support the lifting drive member 41, which is connected to the upper cover 10 through the lifting drive member 41 to realize the opening and closing of the upper cover 10 and the lower cover 20. When the product to be rinsed needs to be placed in the product limiting groove 21, or the rinsed product needs to be taken out of the product limiting groove 21, the lifting drive member 41 retracts to separate the upper cover 10 from the lower cover 20 and open the upper cover 10; when rinsing is required, the lifting drive member 41 descends to cover the upper cover 10 and the lower cover 20 to form the rinsing groove 30, so that the product can be rinsed in the rinsing groove 30. The provision of the lifting drive member 41 improves the convenience of operation.
[0033] As one embodiment, the lifting driving member 41 is a cylinder.
[0034] Further, such as Figure 4 As shown, the lower cover 20 is provided with a first limiting groove 23 and a second limiting groove 24 on opposite sides in the second direction Y. The first limiting groove 23 and the second limiting groove 24 are located in the flushing groove 30 and define a product limiting groove 21. The first limiting groove 23 and the second limiting groove 24 respectively limit the product on both sides in the second direction Y to prevent the product from moving during the flushing process.
[0035] Further, such as Figure 4 As shown, the openings of the first limiting groove 23 and the second limiting groove 24 are arranged opposite each other. After the first limiting groove 23 and the second limiting groove 24 limit the product on both sides of the second direction Y, the flushing liquid in the first flushing channel 34 flows along the third direction Z, and the middle part of the product is cleaned by the flushing liquid in the first flushing channel 34.
[0036] As one embodiment, Figures 3 and 4 As shown, the product supporting surface 22 of the first limiting groove 23 and the product supporting surface 22 of the second limiting groove 24 are at the same position in the first direction X.
[0037] Further, such as Figure 4 As shown, the first limiting groove 23 and the second limiting groove 24 are arc-shaped. The wafer is circular, and the arc shape is adapted to the edge shape of the wafer. The first limiting groove 23 and the second limiting groove 24 limit the wafer to prevent the product from moving during the cleaning process.
[0038] Further, such as Figure 4 As shown, a plurality of product limiting grooves 21 are provided, and adjacent product limiting grooves 21 are spaced apart along the third direction Z. The first direction X, the second direction Y and the third direction Z are respectively perpendicular to each other. Providing multiple product limiting grooves 21 in the rinsing tank 30 allows for simultaneous cleaning of multiple products, thereby improving cleaning efficiency.
[0039] Further, such as Figure 1 As shown, the water inlet 11 is located at one end of the flushing tank 30, and the drain outlet 31 is located at the other end of the flushing tank 30. The flushing liquid enters the flushing tank 30 through the water inlet 11. The water inlet 11 is arranged away from the drain outlet 31. Since the water inlet 11 and the drain outlet 31 are located at both ends, an effective flow channel can be formed in the flushing box, which prolongs the residence time of the flushing liquid in the flushing tank 30, allowing the water to flow more smoothly through the box body, thereby enhancing the cleaning effect.
[0040] Further, such as Figure 4As shown, the flushing groove 30 and the product limiting groove 21 are both arranged on the lower cover 20, and the groove processing is concentrated on the lower cover 20, which is convenient for groove structure processing, reduces production costs, and improves production efficiency.
[0041] Further, such as Figure 1 As shown, the water inlet 11 is opened on the upper cover 10. It can prevent sewage or waste water from flowing back through the water inlet 11, avoiding the source of the flushing liquid from being contaminated.
[0042] In summary, the embodiment of the present invention provides a straight-trough flushing device, and the flushing box body includes an upper cover 10 and a lower cover 20. When the upper cover 10 and the lower cover 20 are closed, a box body is formed. The flushing tank 30 is located inside the upper cover 10 and the lower cover 20, and the lower cover 20 is provided with a product limiting groove 21 for placing the product. When the upper cover 10 is opened, the product limiting groove 21 is provided with a product supporting surface 22. The product is placed in the product limiting groove 21 and supported by the product supporting surface 22. The flushing liquid enters the flushing tank 30 from the water inlet 11. After the product is placed in the product limiting groove 21, a first flushing channel 34 and a second flushing channel 35 are formed on both sides of the product in the thickness direction. After the flushing liquid enters the flushing tank 30, the flushing liquid enters the first flushing channel 34 and the second flushing channel 35 respectively, thereby achieving synchronous cleaning of both sides of the product, simplifying the operation, and improving the cleaning effect.
[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and replacements can be made without departing from the technical principles of the present invention. These improvements and replacements should also be regarded as the scope of protection of the present invention.
