[0046] Example 1

[0047] This embodiment provides a cleaning device, such as Figures 1-17 As shown, the cleaning device includes a moving component 1, a cleaning component 2 and a return material component 3. The cleaning component 2 and the return material component 3 are arranged adjacent to each other, and the moving component 1 is located above the cleaning component 2 and the return material component 3; after the workpiece 4 to be cleaned is cleaned at the cleaning component 2, the moving component 1 can transfer the cleaned workpiece 4 to be cleaned to the return material component 3 for return.

[0048] Specifically, the mobile component 1 is used to realize the grabbing and transfer of the workpiece 4 to be cleaned, grab the cleaned workpiece 4 to be cleaned from the cleaning component 2, and place it on the return material component 3. The cleaning component 2 is mainly used to realize the cleaning of the workpiece 4 to be cleaned; the return material component 3 is mainly used to return the cleaned workpiece 4 to be cleaned. More specifically, the adjacent arrangement of the cleaning component 2 and the return material component 3 can be that the cleaning component 2 and the return material component 3 are arranged side by side, or the tail of the cleaning component 2 is adjacent to the head of the return material component 3. The arrangement is based on the convenience of the mobile component 1 to transfer the workpiece 4 to be cleaned. In this embodiment, the workpiece 4 to be cleaned is placed on the cleaning component 2 for cleaning. After cleaning is completed, the mobile component 1 transfers the cleaned workpiece 4 to be cleaned to the return material component 3 for return.

[0049] In order to clean the debris on the workpiece 4 to be cleaned, the traditional method is: manually transport the workpiece 4 to be cleaned, then manually stack the workpiece 4 to be cleaned, and then manually clean the workpiece 4 to be cleaned, and after cleaning, manually stack and transport the workpiece 4; and when manually cleaning the workpiece 4 to be cleaned, a brush is used, which takes a long time to clean, has a poor cleaning effect, and has a high annual brush consumption cost. It is also labor-intensive, and there are often abnormalities such as the workpiece 4 to be cleaned falling and injuring people or the equipment being scrapped during the cleaning process. After adopting the cleaning device of this embodiment, the method is simplified as follows: manually place the workpiece 4 to be cleaned, the cleaning component 2, the return component 3 and the moving component 1 automatically complete the cleaning work and return the material, and then manually pick up the workpiece 4 to be cleaned. It can be seen that the cleaning device provided by this embodiment replaces traditional manual cleaning with automatic cleaning, thereby improving the cleaning effect and cleaning efficiency.

[0050] When the workpiece 4 to be cleaned is a welding tool, it can effectively prevent tin beads and tin slag from falling onto the mainboard of the air-conditioning outdoor unit, causing quality problems such as short circuit or failure of the entire machine to start, while improving the cleaning time and cleaning effect of the welding tool, saving about 1,000 yuan in brush costs annually, reducing the labor intensity of the operator, and preventing abnormalities such as welding tools falling and injuring people or tools being scrapped during the cleaning process, thus achieving multiple goals at one stroke.

[0051] In a specific embodiment, Figure 1 、 Figure 2 as well as Figure 8 As shown, the cleaning assembly 2 includes a box body 21, a cleaning unit 22 and a drying unit 23. The box body 21 has an inclined surface. The cleaning unit 22 is connected to the lower end of the horizontal plane of the box body 21. The drying unit 23 is arranged at the end of the cleaning unit 22 away from the box body 21; the workpiece 4 to be cleaned reaches the cleaning unit 22 through the inclined surface, and can be dried by the drying unit 23 after cleaning is completed.

[0052] Among them, the box body 21 can be regarded as consisting of two parts, one of which has an inclined surface, and the other part is a cleaning unit 22 with a cavity; in the specific use process, after the operator places the workpiece 4 to be cleaned at the highest point of the box body 21, it will slide down along the inclined surface due to the action of gravity, and then slide to the cleaning unit 22. After the cleaning is completed at the cleaning unit 22, it can be dried by the drying unit 23. It can be seen that the cleaning device provided in this embodiment can remove moisture from the surface of the workpiece 4 to be cleaned after cleaning, without the need for self-heating air drying, effectively saving air drying time. Moreover, in this embodiment, since the box body 21 has an inclined surface, the workpiece 4 to be cleaned can slide to the cleaning unit 22 under the action of gravity. This setting method can reduce the investment in power equipment, save production costs, and enable the workpiece 4 to be cleaned to slide automatically and smoothly.

[0053] In a specific embodiment, Figure 3 、 Figure 5 as well as Figure 6 As shown, the cleaning unit 22 includes a cleaning tank 221 containing cleaning fluid, a receiving tray 222, a solenoid valve 223, and a cleaning air pipe 224. The receiving tray 222 is located within the cleaning tank 221, the solenoid valve 223 is disposed outside the cleaning tank 221, and the cleaning air pipe 224 is connected to the cleaning fluid through the solenoid valve 223. The workpiece 4 to be cleaned can slide onto the receiving tray 222 after passing through the inclined surface. The cleaning fluid is an acidic liquid.

[0054] Specifically, the cleaning tank 221 has a certain depth and contains sufficient cleaning liquid. The receiving tray 222 is located in the cleaning tank 221, and the cleaning liquid can submerge the receiving tray 222, and then submerge the workpiece 4 to be cleaned located on the receiving tray 222. On one side of the cleaning tank 221, a solenoid valve 223 is provided. The input end of the solenoid valve 223 is connected to an external air source, and the output end of the solenoid valve 223 is connected to a cleaning gas charging pipe 224, which extends into the cleaning liquid. In specific use, when the workpiece 4 to be cleaned slides onto the receiving tray 222 via an inclined surface, the solenoid valve 223 is opened, and the external air source enters the cleaning liquid through the solenoid valve 223 and the cleaning gas charging pipe 224, that is, the gas is filled into the cleaning liquid. The high-pressure gas tumbling in the cleaning liquid can effectively clean the workpiece 4 to be cleaned. When the workpiece 4 to be cleaned is an air conditioner electronic component welder, the cleaning unit 22 provided in this embodiment can effectively clean the flux, tin slag, and tin beads on the air conditioner electronic component welder.

[0055] In addition, in one embodiment, Figure 9 As shown, three groups of cleaning and inflation tubes 224 are provided, and the three groups of cleaning and inflation tubes 224 are installed at relevant positions in three circular holes on the wall of the cleaning tank 221. The solenoid valve 223 is installed at relevant positions in the inner holes of the cleaning and inflation tubes 224 and is seamlessly welded by brazing. The material receiving tray 222 is in close contact with the bottom surface of the cleaning tank 221.

[0056] In a specific embodiment, Figure 8 and Figure 9 As shown, the drying unit 23 includes a drying inflation pipe, one end of which is connected to the solenoid valve 223, and the other end of which passes through the side wall of the cleaning tank 221 and extends into the cleaning tank 221, and the drying inflation pipe is located above the liquid level of the cleaning liquid.

[0057] The drying and cleaning air pipes 224 are arranged in parallel, with one end of each connected to the solenoid valve 223. The difference is that the other end of the cleaning air pipe 224 needs to extend into the cleaning liquid, while the other end of the drying air pipe needs to be above the liquid level of the cleaning liquid. In this way, when the cleaning unit 22 completes cleaning the workpiece 4, the moving assembly 1 grabs the workpiece 4 and moves it upward to separate it from the cleaning liquid. At this time, the solenoid valve 223 controls the cleaning air pipe 224 to close and the drying air pipe to open. The external air source blows air through the solenoid valve 223 and the drying air pipe to the cleaned workpiece 4, which can quickly remove moisture from the workpiece 4.

[0058] In addition, the cleaning time of the cleaning unit 22 and the drying time of the drying unit 23 are also set according to actual needs. There are many ways to set them, such as controlling the time relay through PLC to control the working time of the electromagnetic valve 223.

[0059] In a specific embodiment, the cleaning component 2 further includes a first sensing unit 24 for sensing whether there is a workpiece 4 to be cleaned on an inclined surface. The first sensing unit 24 is located on one side of the box body 21 and is in communication with the solenoid valve 223, and is used to start or close the cleaning air pipe 224 through the solenoid valve 223. The first sensing unit 24 includes a first sensing switch. When the first sensing switch senses the workpiece 4 to be cleaned, the solenoid valve 223 activates the cleaning air pipe 224, so that the workpiece 4 to be cleaned can slide into the cleaning tank 221 and then start cleaning. Of course, the soaking time can also be set. For example, when the first sensing switch senses the first fixed time of the workpiece 4 to be cleaned, the solenoid valve 223 activates the cleaning air pipe 224. Then, during the set first fixed time, the workpiece 4 to be cleaned is immersed in the cleaning liquid, making it easier to clean after soaking. This setting method is also feasible.

[0060] The cleaning assembly 2 further includes a second sensing unit 25 for sensing whether the workpiece 4 to be cleaned has started to dry. Figure 1 As shown, the second sensing unit 25 is located on the wall of the cleaning tank 221 and is above the liquid level of the cleaning liquid. The second sensing unit 25 is in communication with the solenoid valve 223 and is used to activate or deactivate the drying and inflation pipe via the solenoid valve 223. The second sensing unit 25 includes a second sensor switch. When the second sensor switch senses the workpiece 4 to be cleaned, indicating that the workpiece 4 has been cleaned and has been moved out of the cleaning tank by the moving assembly 1, the solenoid valve 223 activates the drying and inflation pipe to dry the workpiece 4; otherwise, the drying and inflation pipe is closed.

[0061] In addition, to enable the second induction switch to clearly distinguish whether the workpiece 4 to be cleaned has been removed from the cleaning liquid or is about to be slid into the cleaning liquid, the wall of the cleaning tank 221 used to fix the second induction switch can be slightly higher; in this way, the workpiece 4 to be cleaned will not pass the second induction switch when sliding down, but will pass the second induction switch when moving out of the cleaning tank 221. Furthermore, to better enable the second induction switch to accurately sense the workpiece 4 to be cleaned, the height of the workpiece 4 to be cleaned can be controlled by the moving assembly 1 so that it is flush with the second induction switch.

[0062] In a specific embodiment, Figure 2 and Figure 7 As shown, the return material component 3 includes a return material rack 31, a material receiving unit 32, a sliding unit 33 and a return material platform 34, and the material receiving unit 32, the sliding unit 33 and the return material platform 34 are arranged in sequence on the return material rack 31; wherein, the sliding unit 33 has an inclined surface, the higher side of which is connected to the material receiving unit 32, and the lower side is connected to the return material platform 34; when the workpiece 4 to be cleaned is cleaned and dried, the moving component 1 moves it to the material receiving unit 32, and then slides to the return material platform 34 through the sliding unit 33.

[0063] In a specific embodiment, Figure 2 and Figure 17 As shown, the return material assembly 3 also includes a driving member 35, which is arranged at the material receiving unit 32 and is used to drive the workpiece to be cleaned 4 located on the material receiving unit 32 to move sequentially along the material receiving unit 32 and the sliding unit 33 to the return material platform 34. The driving member 35 is a pneumatic push rod, which is used to drive the workpiece to be cleaned 4 located on the material receiving unit 32 so that it slides down to the return material platform 34 through the sliding unit 33. The pneumatic push rod includes a fixed frame and a push rod body, and the fixed frame includes a horizontal plate and a vertical plate connected in an L-shape. The vertical plate is arranged close to the side of the material receiving unit 32, and the horizontal plate is close to the horizontal surface of the material receiving unit 32. The push rod body is connected to the horizontal plate and can extend and retract in the horizontal direction to push the workpiece to be cleaned 4. When its acting force disappears, the workpiece to be cleaned 4 can slide along the sliding unit 33 under the action of gravity.

[0064] In a specific embodiment, Figure 2 and Figure 6As shown, the return assembly 3 also includes a third sensing unit 36 ​​for sensing the presence of a workpiece 4 to be cleaned on the receiving unit 32. The third sensing unit 36 ​​is positioned on one side of the receiving unit 32 and is in communication with the drive member 35 and the moving assembly 1. The third sensing unit 36 ​​includes a third sensor switch. When the third sensor switch senses the presence of a workpiece 4 to be cleaned, indicating that the workpiece 4 has been cleaned and dried and has been moved to the receiving unit 32 by the moving assembly 1, the drive member 35 is activated, allowing the workpiece 4 to proceed to the next step.

[0065] The recycle assembly 3 also includes a fourth sensing unit 37 for sensing the presence of a workpiece 4 to be cleaned on the recycle platform 34. The fourth sensing unit 37 is disposed on one side of the recycle platform 34 and is in communication with the driver 35. The fourth sensing unit 37 includes a fourth sensor switch. When the fourth sensor switch senses the presence of a workpiece 4 to be cleaned on the recycle platform 34, it controls the driver 35 to stop operating, thereby preventing the workpieces 4 to be cleaned from accumulating on the recycle platform 34.

[0066] In a specific embodiment, Figure 1 and Figure 16 As shown, the moving assembly 1 includes a bracket 11, a slide rail 12, a connector 13, and a clamping unit 14. The slide rail 12 is horizontally arranged on the bracket 11. The connector 13 is arranged on the slide rail 12 and can move horizontally along the slide rail. The clamping unit 14 is connected to the connector 13. The clamping unit 14 can also move up and down to clamp and move the workpiece 4 to be cleaned. The bracket 11 is used to provide support for the slide rail 12. The slide rail 12 includes an upper slide rail 121 and a lower slide rail 122. The clamping unit 14 is connected to the connector 13. The connector 13 can drive the clamping unit 14 to move smoothly along the upper slide rail 121 and the lower slide rail 122. The clamping unit 14 can move up and down, and the output end of the clamping unit 14 can clamp or release the workpiece 4 to be cleaned. When the workpiece 4 to be cleaned is dried at the cleaning component 2, the connecting member 13 drives the clamping unit 14 to move along the slide rail 12 to directly above the cleaning tank 221, the clamping unit 14 moves downward, clamps the workpiece 4 to be cleaned and moves upward, and then the connecting member 13 drives the clamping unit 14 to move along the slide rail 12 to the material receiving unit 32, the clamping unit 14 moves downward, and the clamping unit 14 releases the workpiece 4 to be cleaned, completing the transfer of the workpiece 4 to be cleaned.

[0067] In a specific embodiment, Figure 5 、 Figure 11 as well as Figure 13As shown, the clamping unit 14 includes a telescopic cylinder 141, a clamping cylinder 142, a first clamping plate 143, and a second clamping plate 144. The telescopic cylinder 141 is fixed to the connecting member 13, and the clamping cylinder 142 is connected to the output end of the telescopic cylinder 141. The first clamping plate 143 and the second clamping plate 144 are arranged on both sides of the clamping cylinder 142; the clamping cylinder 142 can drive the first clamping plate 143 and the second clamping plate 144 to move toward or away from each other. When it is necessary to clamp the workpiece 4 to be cleaned, the clamping cylinder 142 drives the first clamping plate 143 and the second clamping plate 144 to move toward each other to clamp the workpiece 4 to be cleaned; when it is necessary to release the workpiece 4 to be cleaned, the clamping cylinder 142 drives the first clamping plate 143 and the second clamping plate 144 to move away from each other to release the workpiece 4 to be cleaned. During this process, the telescopic cylinder 141 can control the height of the clamping cylinder 142, the first clamping plate 143 and the second clamping plate 144 to achieve the clamping, release and transfer of the workpiece 4 to be cleaned.

[0068] In a specific embodiment, the moving assembly 1 further includes a first positioning unit 15, which is provided on the slide rail 12 and is used to limit the first position of the connecting member 13 when it moves along the slide rail 12 in a first direction, so that the clamping unit 14 is exactly located above the cleaning assembly 2; the moving assembly 1 further includes a second positioning unit 16, which is provided on the slide rail 12 and is used to limit the second position of the connecting member 13 when it moves along the slide rail 12 in a second direction, so that the clamping unit 14 is exactly located above the return assembly 3. The first positioning unit 15 and the second positioning unit 16 are both positioning blocks, which are used to control the distance that the connecting member 13 moves along the slide rail 12, so that the clamping unit 14 can be located just above the cleaning assembly 2 or the return assembly 3.

[0069] When the workpiece 4 to be cleaned is an air conditioner electronic component welding device, the specific working process of the cleaning device provided in this embodiment is as follows:

[0070] First, turn on the power to solenoid valve 223. Connect the cleaning air pipe 224 to the solenoid valve 223 that controls the air flow to ensure a clear air supply. Add sufficient cleaning fluid to the cleaning tank 221. The air conditioner electronic component welding equipment is placed on the slope of the housing 21. Under the influence of gravity, it slides downward into the receiving tray 222. After the first sensor switch senses the air conditioner electronic component welding equipment, it sends a signal to the solenoid valve 223, controlling the cleaning air pipe 224 to blow air. High-pressure air tumbles through the cleaning fluid, effectively cleaning the flux, tin slag, and tin beads from the air conditioner electronic component welding equipment. When the set cleaning time is complete, the telescopic cylinder 141 moves downward. The clamping cylinder 142 senses the signal and begins operating. The first and second clamping plates 143 and 144 open left and right to clamp the air conditioner electronic component welding equipment and move upward. After the second sensor switch senses the presence of the air conditioner electronic component welding equipment, air is blown through the drying air pipe to remove moisture from the air conditioner electronic component welding equipment. After the air blowing time is complete, the slide rail 12 drives the connector 13 and the gripping unit 14 to slide together to the second positioning unit 16. After the gripping cylinder 142 senses the signal from the third sensor switch, the first and second clamping plates 143 and 144 are released, placing the air conditioner electronic device welding tool on the receiving unit 32. The pneumatic push rod senses the presence of the air conditioner electronic device welding tool and begins to work and pushes it forward. The air conditioner electronic device welding tool slides onto the workbench under the gravity of the pneumatic push rod. The fourth sensor switch senses the signal and controls the air conditioner electronic device welding tool to stop sliding down. After the operator takes the air conditioner electronic device welding tool for use, another air conditioner electronic device welding tool slides down. The third sensor switch then sends a signal to the slide rail, causing it to drive the connector 13 and the gripping unit 14 to slide to the first positioning unit 15, that is, return to the initial position, and the cleaning work of one air conditioner electronic device welding tool is completed.

[0071] The cleaning device provided in this embodiment adopts an automatic clamping structure to achieve the movement and clamping of welding tools up and down, left and right. The return material component 3 adopts a high and low slope sliding structure to achieve the smooth sliding of the welding tools after cleaning into the workbench, saving time and effort. The cleaning component 2 adopts a high and low slope sliding structure to achieve the smooth sliding of the welding tools before cleaning into the cleaning tank, saving time and effort. The receiving tray adopts a groove structure, so that the welding tools can slide into the groove effectively without deviation, effectively preventing the welding tools from slipping out of the box and splashing water. The cleaning air pipe 224 and the solenoid valve 223 realize air pressure cleaning of the welding tools, which has a good cleaning effect. After the welding tools are cleaned, the drying air pipe connected to the solenoid valve 223 quickly blows away the water on the surface of the welding tools. The cleaning device provided in this embodiment is cleverly designed and simple to process, and achieves automatic cleaning of welding tools, improving the cleaning effect and cleaning efficiency. It can effectively prevent tin beads and tin slag from falling onto the mainboard of the air conditioner outdoor unit, causing quality problems such as short circuit or failure of the entire unit to start. At the same time, it improves the cleaning time and cleaning effect of welding tools, saves about 1,000 yuan in brush costs annually, reduces the labor intensity of operators, and prevents abnormalities such as welding tools falling and injuring people or tools being scrapped during the cleaning process.
