[0026] Some embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0027] In the current process of cleaning packaging containers, since the packaging containers need to be clamped, the clamped portion of the packaging containers is difficult to be effectively cleaned.

[0028] Therefore, the present application creatively proposes a cleaning device for wet electronic chemical packaging containers, which includes a base and a clamping assembly and a spray assembly arranged on the base. When cleaning the container, the container is first clamped by the clamping assembly, and the spray gun is turned on to clean the container. At the same time, cleaning water is supplied to the clamp through the inlet hole, and the cleaning water flows to the spray hole through the flow channel and then sprayed on the container. At the same time, the cleaning water also flows to the container through the groove pressed against the container and the passage channel to clean part of the container located in the clamping assembly. After cleaning, gas is blown into the inlet hole to discharge the cleaning water in the clamp and the cleaning waste water attached to the surface of the clamped part of the container through the outlet hole, thereby effectively cleaning the clamped part of the container and greatly improving the cleaning quality and cleaning efficiency of the container.

[0029] The present invention will be described in detail below through specific embodiments.

[0030] Reference Figures 1 to 3As shown, an embodiment of the present application provides a cleaning device for a wet electronic chemical packaging container 4, the cleaning device includes a base 1 and a clamping assembly 2 and a spray assembly 3 arranged on the base 1, the clamping assembly 2 includes a clamp 21 for clamping the container 4, a flow channel 211 is provided in the clamp 21, and an inlet hole 212 and an outlet hole (not shown) connected to the flow channel 211 are provided on the surface of the clamp 21, the inlet hole 212 is used to connect to a cleaning water source or air source, the clamp 21 has a clamping surface 213 for pressing against the container 4, the clamping surface 213 is provided with a groove 214 and a passage channel 215 connected to the groove 214, and a spray hole 216 connected to the flow channel 211 is provided in the groove 214; the spray assembly 3 includes at least one spray gun 31 arranged on the base 1, and the spray port of the spray gun 31 faces the container 4.

[0031] In some examples, in order to avoid splashing of cleaning waste water during the cleaning process, the cleaning device also includes an openable sealing frame, and the base 1, the clamping assembly 2 and the spray assembly 3 are all arranged in the sealing frame.

[0032] In some examples, the number of the clamps 21 may be one, two, or three or more, as long as they can stably clamp the container 4. In this embodiment, there are two clamps 21.

[0033] The shape of the clamp 21 can be a semicircular ring, a semi-square ring, etc., as long as the two clamps 21 can stably clamp the container 4 after being matched.

[0034] It is understandable that, in order to stably clamp the container 4, the shape of the clamping surface 213 is generally adapted to the outer shape of the container 4. For example, when the container 4 is cylindrical, the clamping surface 213 is an arc-shaped curved surface.

[0035] In addition, when clamping the container 4, the clamp 21 can only clamp any two opposite positions on the surface of the container 4, and the clamping area is small (can be regarded as line contact), that is, there is a gap between the clamp 21 and the container 4 except for the clamped position. Specifically, the gap area between the clamp 21 and the container 4 can be expanded by expanding the area of ​​the groove 214 and / or the passage channel 215, thereby fully cleaning the surface of the container 4 located at the clamping component 2.

[0036] It should be noted that the composition of the cleaning water source can be ultrapure water, or pure water that meets the cleaning requirements, or it can also be a solution with other chemical components added that meets the requirements. The gas source is generally an inert gas, such as nitrogen, etc. At the same time, in order to achieve a better drying effect, nitrogen with a preset temperature is generally selected, and the preset temperature is greater than 30°C.

[0037] Specifically, when cleaning the container 4, the sealing rack is opened, and then the container 4 can be placed at the clamping assembly 2 by manual or mechanical grasping, and then the container 4 is clamped by the clamping assembly 2, and the sealing rack is closed; then the spray gun 31 is started to clean the container 4, and the inlet hole 212 and the cleaning water source are connected, and the cleaning water flows into the flow channel 211 through the inlet hole 212, and then flows to the spray hole 216, thereby realizing the cleaning of part of the container 4 at the clamping assembly 2, wherein a part of the cleaning water will flow to part of the container 4 at the clamping assembly 2 through the groove 214 and the passage channel 215, and the cleaning waste water is discharged from the outflow hole, thereby realizing the effective and sufficient cleaning of part of the container 4 at the clamping assembly 2, and improving the cleaning quality and cleaning efficiency. After the cleaning is completed, the inlet hole 212 is connected to the air source, and the cleaning water in the fixture and the cleaning waste water attached to the surface of the clamped part of the container 4 are blown dry by nitrogen, so as to avoid the residual cleaning water remaining on the surface of the container 4 after the fixture 21 is opened.

[0038] In some examples, the flow channel 211 includes a main channel 2111 extending circumferentially along the clamp 21 and at least two branch channels 2112 connected to the main channel 2111, the main channel 2111 is connected to the inlet hole 212, there are at least two outflow holes that are connected one-to-one with the branch channels 2112, and at least two spray holes 216 are provided in the groove 214, and the spray holes 216 are connected one-to-one with the branch channels 2112.

[0039] Specifically, when the cleaning water flows into the flow channel 211, it first flows into the main channel 2111, then flows to the branch channel 2112, and flows to the corresponding spray hole 216 through the branch channel 2112, thereby increasing the area of ​​the container 4 to be rinsed and improving the cleaning efficiency of the container 4. After the cleaning is completed, the waste water is quickly discharged through the multiple outflow holes.

[0040] In some examples, the passage channel 215 includes a first channel 2151 and a second channel 2152 that are staggered with each other. The first channel 2151 extends along the circumference of the clamp 21 to the two end faces of the clamp 21, and the second channel 2152 passes through the groove 214 along the axial direction of the clamp 21 and extends to the two end faces of the clamp 21. The first channel 2151 and the second channel 2152 increase the gap area between the clamping surface 213 and the container 4, so that the cleaning water flowing out through the spray hole 216 can clean more surfaces of the container 4; at the same time, the cleaning waste water can be directly discharged through the first channel 2151 and the second channel 2152; in some examples, the outflow hole can be set at the same position as any one or more holes of the passage channel 215 extending to the end face of the clamp 21, that is, these end holes of the passage channel 215 are regarded as outflow holes.

[0041] In this embodiment, the holes formed by the second channel 2152 extending to the two end surfaces of the clamp 21 are outflow holes.

[0042] In consideration of processing convenience and cleaning effect, the first channel 2151 and the second channel 2152 are arranged perpendicular to each other, and the axis of the second channel 2152 is arranged parallel to the axial direction of the fixture 21 .

[0043] Specifically, after the cleaning water is sprayed out from the spray hole 216, part of the cleaning water will flow along the "pipeline" formed between the groove 214 and the container 4, and the passage channel 215 and the container 4 to clean the portion of the container 4 in the clamping assembly 2; and the staggered first channel 2151 and the second channel 2152 can not only ensure the stability of the clamping of the container 4, but also further expand the cleaning area of ​​the surface of the container 4.

[0044] In some examples, reference Figure 2 and Figure 3 As shown, at least one auxiliary hole 217 communicating with the flow channel 211 is provided in the passage channel 215. In this embodiment, two auxiliary holes 217 are provided in each second channel 2152, and the two auxiliary holes 217 are symmetrically arranged about the groove 214. Accordingly, in order to improve the flow efficiency of the cleaning water and thus improve the cleaning efficiency of the container 4, the flow channel 211 also includes a diversion channel 2113 arranged along the axial direction of the clamp 21, and the diversion channel 2113 passes through the diversion channel 2112 and is respectively connected to the two auxiliary holes 217 in the same second channel 2152, so as to divert the cleaning water to the two auxiliary holes 217.

[0045] It can be understood that the inlet hole 212 can be a hole of a regular shape such as a round hole, a square hole, or any irregular polygonal hole, as long as the cleaning water can be stably supplied into the flow channel 211 through it; the spray hole 216 and the auxiliary hole 217 can also be a hole of a regular shape such as a round hole, a square hole, or any irregular polygonal hole, as long as the cleaning water can be stably output.

[0046] In addition, the cross-sections of the first channel 2151 and the second channel 2152 can be semicircular, rectangular, or the like. In the present embodiment, in order to facilitate processing and the continuous and stable flow of cleaning water, the cross-sections of the first channel 2151 and the second channel 2152 are both set to be semicircular, and the cross-sections of the main channel 2111 and the branch channel 2112 are both set to be circular.

[0047] In some examples, protrusions are evenly distributed on the clamping surface 213 , so that the container 4 can be stably clamped while there is more space for the flow of cleaning water between the clamping surface 213 , thereby effectively increasing the cleaning area of ​​the container 4 .

[0048] The shape of the protrusion may be a hemispherical shape, a square shape, etc. In the present embodiment, the shape of the protrusion is a hemispherical shape.

[0049] In some examples, reference Figure 1 As shown, a storage cavity 11 with an opening is provided in the base 1, and the opening faces the container 4 clamped by the clamp 21 to receive the cleaning waste water of the cleaning container 4. A waste discharge pipeline 12 connected with the storage cavity 11 is also provided on one side of the base 1 to discharge the cleaning waste water in the storage cavity 11. In the process of cleaning the container 4, the cleaning water continuously falls into the storage cavity 11 due to gravity, and the user selects the drainage time and drainage amount according to the needs.

[0050] In some examples, a water quality detector for detecting the quality of cleaning wastewater is provided in the storage chamber 11, and a circulation pipeline 13 connected to the inlet hole 212 and the storage chamber 11 respectively is provided on one side of the base 1. A water suction pump and a valve 14 electrically connected to the water quality detector are provided on the circulation pipeline 13 to extract cleaning wastewater reaching a preset value into the flow channel 211.

[0051] It is understandable that the waste discharge pipeline 12 generally also includes a drain valve for controlling the on-off of the waste discharge pipeline 12. In this embodiment, the drain valve is connected to the water quality detector.

[0052] Specifically, when the container 4 is cleaned with water, the cleaning waste water after cleaning will fall into the storage chamber 11, and the water quality detector can detect the cleaning waste water in time. If the cleaning waste water does not reach the preset value, the drain valve is opened to discharge the unqualified cleaning water; and when the water quality detector detects that the waste water in the storage chamber 11 reaches the preset value, the drain valve is closed, and the water suction pump and valve 14 are opened, so that the cleaning waste water that reaches the preset value in the storage chamber 11 is transported to the flow channel 211 to clean the container 4, thereby recycling water resources.

[0053] In some examples, the spray assembly 3 includes at least two spray guns 31 spaced apart along the circumference of the base 1. The multiple spray guns 31 are used to clean the container 4 in multiple angles and in all directions.

[0054] In some examples, the spray assembly 3 further includes a bracket 33 and a mounting bracket 32 ​​slidably disposed on the bracket 33, the mounting bracket 32 ​​includes a connecting portion 321 and a mounting portion 322 rotatably connected to the connecting portion 321, and the mounting portion 322 is used to mount the spray gun 31. Specifically, the height of the mounting bracket 32 ​​relative to the base 1 can be adjusted by sliding the mounting bracket 32, so that the height of the spray gun 31 relative to the container 4 can be adjusted; then, the angle of the spray gun 31 can be adjusted by rotating the mounting portion 322, so that the container 4 can be sprayed better.

[0055] In some examples, the cleaning device further includes a purge assembly 5 disposed on the base 1 , the purge assembly 5 includes a purge gun 51 , and an air outlet of the purge gun 51 faces the container 4 clamped by the clamping assembly 2 .

[0056] After the cleaning of the container 4 is completed, the moisture on the surface of the container 4 is quickly blown away by the purge gun 51; in this embodiment, the purge gun 51 can be connected to a nitrogen gas source to purge the container 4 with nitrogen.
