[0042] To make the technical problems solved, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0043] like Figures 1 to 7 As shown, an embodiment of the present invention provides a cleaning device including a cleaning component 1, a liquid storage tank 2, and a recovery tank 3. The cleaning component 1 is provided with a spray channel 14 and a recovery channel 15. One end of the spray channel 14 is connected to the liquid storage tank 2 or the recovery tank 3, and the other end of the spray channel 14 is used to spray out cleaning liquid.

[0044] The recovery channel 15 is used to recover the cleaning fluid sprayed and dropped from the other end of the spray channel 14 into the recovery chamber 3. A negative pressure device is used to create a negative pressure in the recovery chamber 3, so that the cleaning fluid recovered in the recovery channel 15 can smoothly enter the recovery chamber 3.

[0045] The liquid storage tank 2 is used to store the cleaning fluid. One end of the spray channel 14 can be selectively connected to either the liquid storage tank 2 or the recovery tank 3, switching according to the status of the cleaning equipment. When preparing for cleaning, one end of the spray channel 14 is connected to the recovery tank 3, and the negative pressure device connected to the recovery tank 3 is immediately activated, creating negative pressure inside the recovery tank 3 and the spray channel 14. This negative pressure mechanism creates a strong adsorption force, which can restrain the cleaning fluid even when impacted by the airflow inside the PCB processing equipment spindle, ensuring that it does not splash or overflow, thus reducing waste.

[0046] During cleaning, one end of the spray channel 14 is connected to the liquid storage tank 2, and the cleaning liquid is sprayed out through the spray channel 14 to clean the object that needs to be cleaned.

[0047] In this embodiment, by setting up a spray channel 14 and a recovery channel 15, the cleaning and recovery requirements of the cleaning fluid can be met. The spray channel 14 has flexible connectivity, and can freely switch between the storage tank 2 and the recovery tank 3 according to the actual working state. When the cleaning equipment is in a non-cleaning state, by connecting the spray channel 14 and the recovery tank 3, the impact of the main shaft airflow on the cleaning fluid can be effectively blocked, reducing problems such as cleaning fluid splashing and leakage caused by airflow impact, thus ensuring the stable operation of the cleaning equipment.

[0048] In one embodiment, the cleaning equipment further includes a reversing component 4, which controls one end of the spray channel 14 to connect to the liquid storage tank 2 or the recovery tank 3. The reversing component 4 enables automated switching of the connection position of the spray channel 14.

[0049] Preferably, the reversing component 4 is a two-position three-way solenoid valve, mainly comprising a solenoid coil, a valve core, and a valve body. The solenoid coil is wound around the outside of the valve body and generates a magnetic field when energized. The valve core is located inside the valve body and can move linearly. The valve body has three channel interfaces, namely the first interface 41, the second interface 42, and the third interface 43. The linear movement of the valve core enables the connection of different channel interfaces. The reversing component 4 ensures that the spray channel 14 is connected to only one compartment at a time, preventing the fresh cleaning liquid in the storage compartment 2 from mixing with the recycled cleaning liquid in the recovery compartment 3, effectively preventing cross-contamination.

[0050] Specifically, the reversing component 4 has a first interface 41, a second interface 42, and a third interface 43. The first interface 41 is connected to the spray channel 14, the second interface 42 is connected to the storage tank 2, and the third interface 43 is connected to the recovery tank 3. When the first interface 41 and the second interface 42 are connected, the spray channel 14 is connected to the storage tank 2. The cleaning fluid in the storage tank 2 enters the spray channel 14 after passing through the second interface 42 and the first interface 41 in sequence. The cleaning fluid is then sprayed out through the spray channel 14 to clean the chuck on the spindle of the PCB processing equipment.

[0051] When the first interface 41 is connected to the third interface 43, the spray channel 14 is connected to the recovery chamber 3, which can effectively block the impact of the main shaft airflow on the cleaning fluid.

[0052] In other alternative embodiments, the reversing element 4 is a manual reversing valve, a pneumatic reversing valve, a hydraulic reversing valve, or a mechanical reversing valve.

[0053] In one embodiment, the cleaning equipment further includes an inlet pipe 5 and an outlet pipe 6. The inlet pipe 5 connects the spray channel 14 to the storage tank 2, and the outlet pipe 6 connects the spray channel 14 to the recovery tank 3 or the recovery channel 15 to the recovery tank 3. When in a non-cleaning state, the spray channel 14 is connected to the recovery tank 3 via the outlet pipe 6. When in a cleaning state, the cleaning fluid in the storage tank 2 is transported to the spray channel 14 via the inlet pipe 5. The spray channel 14 sprays cleaning fluid to clean the spindle chuck. The cleaning fluid that falls off after rinsing is collected in the recovery channel 15, and the recovery channel 15 transports the recovered cleaning fluid to the recovery tank 3 via the outlet pipe 6.

[0054] In one embodiment, the cleaning equipment further includes a throttle valve 51, which is disposed in the liquid inlet pipe 5. The throttle valve 51 is used to adjust the flow rate of the liquid inlet pipe 5, thereby adjusting the amount of cleaning liquid sprayed in the spray channel 14, thereby improving cleaning efficiency and minimizing cleaning liquid waste.

[0055] In one embodiment, the liquid outlet pipeline 6 includes a first pipeline 61 and a second pipeline 62. The first pipeline 61 connects the liquid spraying channel 14 and the recovery chamber 3, and the second pipeline 62 connects the recovery channel 15 and the recovery chamber 3. By providing two pipelines, the liquid spraying channel 14 can be connected to the liquid storage chamber 2, and the liquid spraying channel 14 can be connected to the recovery chamber 3, respectively.

[0056] When the first interface 41 is connected to the third interface 43, the spray channel 14 is connected to the recovery chamber 3 through the first pipe 61, and the recovery channel 15 is connected to the recovery chamber 3 through the second pipe 62. When the negative pressure equipment is started, negative pressure is formed in the spray channel 14 and the recovery channel 15 to reduce the impact of the main shaft airflow on the cleaning fluid.

[0057] When the first interface 41 is connected to the second interface 42, the spray channel 14 is connected to the storage tank 2 through the inlet pipe 5, and the cleaning fluid in the storage tank 2 is transported to the spray channel 14 through the inlet pipe 5. The recovery channel 15 is connected to the recovery tank 3 through the second pipe 62, and the recovered cleaning fluid is transported to the recovery tank 3 through the second pipe 62.

[0058] In one embodiment, the liquid outlet pipeline 6 further includes a third pipeline 63 and a first tee connector 64. The first tee connector 64 has a first connecting end, a second connecting end and a third connecting end. The first pipeline 61 can connect the first connecting end and the liquid spraying channel 14. The second pipeline 62 connects the second connecting end and the recovery channel 15. The third pipeline 63 connects the third connecting end and the recovery chamber 3.

[0059] The first tee connector 64 serves as a connecting hub, with its three ends connected to the first pipe 61, the second pipe 62, and the third pipe 63, respectively. The second pipe 62 and the third pipe 63 are connected through the first tee connector 64, thereby connecting the recovery channel 15 to the recovery chamber 3. When the first interface 41 and the third interface 43 are connected, the liquid spraying channel 14 is connected to the recovery chamber 3 through the first tee connector 64, the first pipe 61, and the third pipe 63.

[0060] The first tee connector 64 connects the first pipeline 61 and the second pipeline 62 to the third pipeline 63, and then the third pipeline 63 is connected to the recovery bin 3, which simplifies the internal piping structure of the equipment.

[0061] In one embodiment, the first tee connector 64 is a Y-type tee connector or a T-type tee connector.

[0062] In one embodiment, multiple cleaning components 1 are provided, and multiple liquid inlet pipes 5 are provided and connected in parallel. Each liquid inlet pipe 5 connects the liquid storage tank 2 and the corresponding liquid spraying channel 14 of the cleaning component 1. The multiple liquid inlet pipes 5 are connected in parallel between the liquid storage tank 2 and the corresponding liquid spraying channel 14 of the cleaning component 1. Each liquid inlet pipe 5 is independent of each other and does not interfere with each other, ensuring that each cleaning component 1 can obtain a stable supply of cleaning fluid.

[0063] Each liquid inlet pipe 5 is equipped with a throttle valve 51. By adjusting the throttle valve 51, the amount of liquid sprayed from the spray channel 14 of each cleaning component 1 can be made consistent.

[0064] Multiple outlet pipes 6 are provided and connected in parallel. Each outlet pipe 6 connects the recovery chamber 3 to the spray channel 14 or the recovery channel 15 of the corresponding cleaning component 1. Specifically, the recovery chamber 3 is connected to the spray channel 14 of each cleaning component 1 through the first pipe 61 and the third pipe 63 of the corresponding outlet pipe 6. The recovery chamber 3 is connected to the recovery channel 15 of each cleaning component 1 through the second pipe 62 and the third pipe 63 of the corresponding outlet pipe 6, thereby realizing the recovery of cleaning fluid from each cleaning component 1.

[0065] It is understood that in this embodiment, multiple first tee connectors 64 are provided, matching the number of cleaning components 1, and multiple reversing components 4 are provided, matching the number of cleaning components 1. When the first interface 41 of the reversing component 4 is connected to the third interface 43, the spray channel 14 and the recovery chamber 3 are connected through the corresponding first tee connectors 64, first pipe 61, and third pipe 63. When the reversing component 4 switches states, the spray channel 14 is disconnected from the first pipe 61, and simultaneously connected to the inlet pipe 5, realizing the delivery of cleaning fluid. The second pipe 62 is connected to the third pipe 63, recovering the wastewater in the recovery channel 15 to the recovery chamber 3.

[0066] In one embodiment, the cleaning equipment further includes a first main pipeline 7 and a second main pipeline 8. The liquid storage tank 2 is connected to a plurality of liquid inlet pipelines 5 through the first main pipeline 7, and the recovery tank 3 is connected to a plurality of liquid outlet pipelines 6 through the second main pipeline 8.

[0067] The cleaning fluid is distributed to multiple inlet pipes 5 via the first main pipe 7, ensuring a stable and uniform flow rate for each inlet pipe 5. The cleaning fluid from multiple outlet pipes 6 is collected in the recovery chamber 3 via the second main pipe 8, facilitating centralized processing of the recovered cleaning fluid.

[0068] The first main pipeline 7 and each inlet pipeline 5 can be connected by a second tee connector at their intersection, and the second main pipeline 8 and each outlet pipeline 6 can be connected by a third tee connector at their intersection.

[0069] In one embodiment, the cleaning equipment further includes a pressure regulating valve 21 and a reversing valve 22. The inlet of the pressure regulating valve 21 is connected to a first air source device, and the outlet of the pressure regulating valve 21 is connected to the inlet of the reversing valve 22. The outlet of the reversing valve 22 is connected to the liquid storage tank 2. The reversing valve 22 is used to control the connection or disconnection between the first air source device and the liquid storage tank 2. The pressure regulating valve 21 can adjust the gas pressure input from the first air source device to a suitable range, and the stable gas pressure acts on the cleaning liquid in the liquid storage tank 2 to ensure that the pressure of the cleaning liquid sprayed from the spray channel 14 is constant.

[0070] The pressure regulating valve 21 typically regulates fluid pressure through a feedback mechanism. When the inlet pressure changes or the outlet load changes, the pressure regulating valve 21 automatically adjusts the position of its internal valve core to maintain a stable outlet pressure. The pressure regulating valve 21 can be a conventional direct-acting valve 21, a pilot-operated valve 21, or an electrically operated valve 21; the specific structure of the pressure regulating valve 21 will not be described in detail here.

[0071] The directional valve 22 can be a solenoid directional valve, an electro-hydraulic directional valve, a manual directional valve, or a pneumatic directional valve.

[0072] In one embodiment, the cleaning equipment further includes a solenoid valve 31 and a vacuum generator 32. The vacuum generator 32 is connected between the recovery chamber 3 and the solenoid valve 31. The solenoid valve 31 is used to control the connection between the second air source device and the vacuum generator 32. When the solenoid valve 31 controls the connection between the second air source device and the vacuum generator 32, a negative pressure is formed in the recovery chamber 3 through the vacuum generator 32.

[0073] When the injection channel 14 is connected to the recovery chamber 3, the vacuum generator 32 creates negative pressure in both the return oil channel and the injection channel 14, which helps to recover the cleaning fluid in the spindle chuck, the injection channel, and the recovery channel 15 into the recovery chamber 3.

[0074] Among them, the solenoid valve 31 is preferably a vacuum solenoid valve.

[0075] In one embodiment, a liquid level sensor 23 is provided on the liquid storage tank 2. The liquid level sensor 23 is used to detect the liquid level of the cleaning liquid in the liquid storage tank 2. The liquid level sensor 23 can detect the amount of cleaning liquid stored in the liquid storage tank 2 so that the cleaning liquid can be replenished in a timely manner.

[0076] In one embodiment, the cleaning component 1 is provided with a cleaning component 16, which is detachably connected to the spray channel 14, allowing for quick assembly and disassembly. The cleaning component 16 is used to clean the chuck on the spindle of the PCB processing equipment.

[0077] The cleaning component 16 includes a brush head 161 and a brush rod 162. The brush head 161 is mounted on the brush rod 162, which is inserted into the end of the spray channel 14 furthest from the liquid reservoir 2, allowing the cleaning fluid to be sprayed out from the gap between the spray channel 14 and the brush rod 162. After the cleaning fluid is sprayed out, it wets the brush head 161 and washes away dust, debris, and other impurities adhering to the inside of the spindle chuck. After spraying the cleaning fluid continuously for a period of time, stubborn residues gradually soften under the wetting and dissolving effect of the cleaning fluid. After stopping the spraying, the brush head 161 is inserted into the inside of the chuck to precisely wipe and scrape away the softened residues, improving the cleanliness of the spindle chuck.

[0078] In one embodiment, the cleaning device further includes a base 9, on which the cleaning component 1 is connected. The base 9 has a first cavity 91 and a second cavity 92, with the second cavity 92 being closer to the liquid storage tank 2 than the first cavity 91. One end of the cleaning component 1 is disposed in the second cavity 92 and blocks the first cavity 91 from the second cavity 92, while the other end of the cleaning component 1 protrudes from the first cavity 91. The first cavity 91 is connected to the spray channel 14, and the second cavity 92 is connected to the recovery channel 15.

[0079] The second chamber 92 is connected to the spray channel 14. After the cleaning fluid flows out of the storage tank 2, it passes through the second chamber 92 and enters the spray channel 14. The first chamber 91 is connected to the recovery channel 15. The recovered cleaning fluid passes through the recovery channel 15 and the first chamber 91 in sequence before entering the recovery tank 3. The cleaning component 1 blocks the first chamber 91 and the second chamber 92, forming a barrier in physical structure, so that the cleaning fluid flows in an orderly manner in different chambers. New cleaning fluid is sprayed out from the first chamber 91 through the spray channel 14, and the used cleaning fluid flows into the second chamber 92 through the recovery channel 15, effectively preventing the cleaning fluid from leaking or flowing between the two chambers.

[0080] In one embodiment, the cleaning component 1 includes a first cleaning component 11 and a second cleaning component 12. The first cleaning component 11 is connected to the second cleaning component 12. The end of the first cleaning component 11 away from the second cleaning component 12 can spray cleaning liquid. The cleaning liquid is sprayed from the first cleaning component 11, and the spray channel 14 passes through the first cleaning component 11 and the second cleaning component 12 in sequence. Preferably, the spray channel 14 extends along the central axis of the cleaning component 1.

[0081] The spray channel 14 includes a first channel 141 and a second channel 142 that are interconnected. The first channel 141 is disposed inside the first cleaning component 11, and the second channel 142 is disposed inside the second cleaning component 12. The second channel 142 connects the first channel 141 and the liquid storage tank 2. The cleaning liquid flows through the second channel 142 and the first channel 141 in sequence and is then sprayed out from the first cleaning component 11.

[0082] The second cleaning component 12 is provided with a top screw opening 121. By installing a top screw in the top screw opening 121, the cleaning component 16 can be disassembled and installed.

[0083] In one embodiment, the cleaning component 1 further includes a third cleaning component 13, which is sleeved outside the first cleaning component 11 and connected to the second cleaning component 12. The recovery channel 15 includes a third channel 151 and a fourth channel 152 that are interconnected. The third channel 151 is formed between the first cleaning component 11 and the third cleaning component 13, and the fourth channel 152 is disposed in the second cleaning component 12. The end of the fourth channel 152 away from the third channel 151 is connected to the first cavity 91. The third channel 151 is located outside the first cleaning component 11 and can collect the cleaning liquid that is sprayed out by the first cleaning component 11 in a timely manner and guide it to flow to the fourth channel 152. After the cleaning liquid flows through the third channel 151 and the fourth channel 152 in sequence, it is transported into the first cavity 91 and finally into the recovery chamber 3.

[0084] In one embodiment, the fourth channel 152 includes multiple sub-channels 1521 arranged around the third channel 151, with each sub-channel 1521 connected to the third channel 151 and the first cavity 91. The multiple sub-channels 1521 facilitate the diversion of the cleaning fluid within the third channel 151. After the cleaning fluid flows out of the third channel 151, it can enter the sub-channels 1521 from multiple directions, reducing the possibility of cleaning fluid accumulation and splashing due to insufficient recovery speed in a single channel, thus making the recovery process more efficient.

[0085] In one embodiment, the cleaning component 1 is provided with a guide component 17, which is sleeved on the outside of the third cleaning component 13. The guide component 17 is used to guide the falling cleaning fluid into the recovery channel 15. The guide component 17 guides the falling cleaning fluid into the recovery channel 15, which can effectively prevent the cleaning fluid from splashing onto the equipment workbench or other parts, keeping the work area clean.

[0086] In one embodiment, the base 9 is provided with an inlet 93 and a return port 94. The inlet 93 is connected to the second cavity 92, and the return port 94 is connected to the first cavity 91. The cleaning fluid supplied by the storage tank 2 enters the second cavity 92 through the inlet 93 and is then sprayed out through the spray channel 14. After use, the cleaning fluid is guided by the guide member 17, flows into the first cavity 91 through the recovery channel 15, and is discharged into the recovery tank 3 through the return port 94.

[0087] In one embodiment, a protective cover 96 and a sealing cover 95 are connected to the base 9. The sealing cover 95 is installed on the base 9 and seals the first cavity 91. The sealing cover 95 is provided with a through hole 951 for the cleaning component 1 to pass through.
