[0001] The present application relates to the technical field of electronic product production, in particular to a cleaning device. BACKGROUND

[0002] In the processing of electronic products (in particular connector products), foreign matter is easily adhered to the surface of the products, which affects many processing procedures. Therefore, in order to ensure the smooth processing of the products, the surface of the products needs to be cleaned.

[0003] At present, the cleaning of the products is mainly achieved by placing the products to be cleaned in a cleaning cavity, and then blowing air to the products to be cleaned through a blowing pipe. However, the current cleaning device cannot ensure the cleanliness of the cleaning cavity, and it is inconvenient to clean the dust on the surface of the products due to static electricity, resulting in poor cleaning effect. SUMMARY

[0004] Therefore, the technical problem to be solved by the present application is to overcome the defects that the cleaning device for cleaning electronic products cannot ensure the cleanliness of the cleaning cavity, and it is inconvenient to clean the dust on the surface of the products due to static electricity, resulting in poor cleaning effect, so as to provide a cleaning device.

[0005] According to the cleaning device provided by the present application, the cleaning device comprises a cleaning table, which is internally provided with a cleaning cavity, and the cleaning cavity is provided with an opening on one side along the width direction;

[0006] A fresh air filtering assembly is used to deliver gas loaded with electric charge into the cleaning cavity and form a wind wall. The fresh air filtering assembly comprises a fan which is communicated with the opposite upper ends of the cleaning cavity along the height direction. The fan is used to deliver external gas into the cleaning cavity. The air outlet end of the fan is sequentially provided with a filter screen and a static electricity ion screen from top to bottom along the height direction. The static electricity ion screen is used to load positive and negative charges to the gas passing therethrough.

[0007] Two mounting columns are symmetrically arranged on both sides of the cleaning cavity along the length direction. The two mounting columns are arranged in parallel to the width direction.

[0008] A connecting column is connected between the two mounting columns in parallel to the length direction. The two ends of the connecting column along the length direction are respectively rotationally connected to the two mounting columns along the width direction and locked by a first locking assembly.

[0009] The blowing head is rotationally connected to the connecting column in the length direction and is locked by a second locking assembly; an air inlet end of the blowing head is communicated with a blowing pump for conveying compressed gas to the blowing head; and an air outlet end of the blowing head is used for blowing compressed gas to the product to be cleaned, and the projection of the air outlet end of the blowing head along the height direction falls within the range of the air outlet end of the fan.

Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0051] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0052] like Figures 1 to 5 The image shows a cleaning device provided in this embodiment, applied to cleaning connector products. The cleaning device includes a cleaning table 1 and a fresh air filter assembly. The cleaning table 1 has a cleaning chamber 11, and the cleaning chamber 11 has an opening 111 on one side along its width. The fresh air filter assembly is used to deliver charged gas into the cleaning chamber 11 and form an air wall. The fresh air filter assembly includes a fan 21 connected to the upper end of the cleaning chamber 11 along its height. The fan 21 is used to deliver outside gas into the cleaning chamber 11. The outlet end of the fan 21 is provided with a filter screen 22 and an antistatic ion screen 23 arranged sequentially from top to bottom along its height. The antistatic ion screen 23 is used to load positive and negative charges onto the gas passing through the antistatic ion screen 23. The cleaning chamber 11 contains... Two mounting posts 31 are symmetrically arranged on both sides along the length direction, and both mounting posts 31 are arranged parallel to the width direction. A connecting post 32 connects the two mounting posts 31 along the length direction. The two ends of the connecting post 32 along the length direction are respectively rotatably connected to the two mounting posts 31 around the width direction and locked by a first locking assembly. An air blowing head 33 is rotatably connected to the connecting post 32 around the length direction and is locked by a second locking assembly. The air inlet end of the air blowing head 33 is connected to an air pump (not shown in the figure), which is used to deliver compressed gas for cleaning to the air blowing head 33. The air outlet end of the air blowing head 33 is used to blow compressed gas to the product to be cleaned, and the projection of the air outlet end of the air blowing head 33 along the height direction falls within the range of the air outlet end of the fan 21. It can be understood that the height direction, width direction and length direction mentioned in this embodiment refer to Figure 1 or Figure 2 or Figure 4 The height, width, and length directions are shown.

[0053] Compared with the prior art, the cleaning device in this embodiment has a fan 21 connected to the upper end of the cleaning chamber 11 along the height direction. The outlet of the fan 21 is sequentially equipped with a filter 22 and an antistatic ionization mesh 23 facing the cleaning chamber 11. When the connector product to be cleaned is placed into the cleaning chamber 11 through the opening 111, the fan 21 is activated to draw in external air. The air is then filtered and dust-removed by the filter 22, and then the antistatic ionization mesh 23 applies positive and negative charges to the external air. Finally, the external air, now loaded with positive and negative charges, forms an airflow that blows onto the connector product to be cleaned. This neutralizes the static electricity on the surface of the connector product, ensuring the airflow is effective. The compressed gas blown out by the blower head 33 can quickly and efficiently blow off the dust that is electrostatically adsorbed on the surface of the connector product for cleaning. Since the projection of the air outlet of the blower head 33 and the connector product to be cleaned along the height direction both fall within the range of the air outlet of the blower 21, the airflow formed by the external gas blown out from the air outlet of the blower 21 can form an air wall surrounding the air outlet of the blower head 33 and the connector product to be cleaned. The air wall is arranged from top to bottom along the height direction, which can effectively prevent unfiltered gas from the outside from entering the cleaning chamber 11 through the opening 111 during the cleaning process, thereby ensuring the cleanliness of the cleaning chamber 11 and improving the cleaning effect on the connector product. Furthermore, by rotating both ends of the connecting post 32 around its width direction and connecting them to two mounting posts 31 respectively, and locking them with a first locking component, and simultaneously rotating the air head 33 around its length direction and connecting it to the connecting post 32, and locking it with a second locking component, the air head 33 can be locked according to the different models and types of connector products to be cleaned. This can be achieved by unlocking the first locking component and / or the second locking component, adjusting the air head 33 to rotate relative to the mounting post 31 around its width direction along with the connecting post 32 to the required angle, and then locking the first locking component, and / or adjusting the air head 33 to rotate relative to the connecting post 32 around its length direction to the required angle, and then locking the second locking component. This allows for adjusting the air head 33 to rotate around its length direction and / or around its width direction to different angle positions and locking them, meeting the different cleaning needs of different models and types of connector products to be cleaned, and providing good versatility.

[0054] like Figures 4 to 6As shown, in some embodiments of the present invention, the connecting post 32 is connected to an elastic connecting portion 34 at both ends along its length. A first through hole 341 is formed through the elastic connecting portion 34 along its width, through which the mounting post 31 passes. A first opening 342 is connected to the surrounding wall of the first through hole 341, extending through the elastic connecting portion 34 along its width. First threaded holes are correspondingly provided on the two surrounding walls of the first opening 342, and these threaded holes are arranged perpendicular to the width direction. The first locking assembly includes components connected to the first threaded holes. A matching first locking bolt 41; the first through hole 341 has a closed state in which the first locking bolt 41 is tightened in the first threaded hole, causing the two walls of the first through hole 342 to approach each other, and an expanded state in which the first locking bolt 41 is loosened from the first threaded hole, causing the two walls of the first through hole 342 to move away from each other; when the first through hole 341 is in the closed state, the walls of the first through hole 341 clamp the mounting post 31; when the first through hole 341 is in the expanded state, the first through hole 341 and the mounting post 31 are in clearance fit. When the air blower head 33 needs to be adjusted to the required angle relative to the mounting post 31 along the width direction, along with the connecting post 32, according to the actual cleaning requirements, first loosen or unscrew the first locking bolt 41 from the first threaded hole. This allows the two walls of the first through-hole 342 to move away from each other under the action of their own elastic restoring force, switching the first through-hole 341 to the expanded state. At this time, the connecting post 32 can be rotated relative to the mounting post 31 in the width direction, thereby adjusting the air blower head 33 to the required angle in the width direction to meet different cleaning requirements and providing strong versatility. Simultaneously, after rotating the air blower head 33 to the required angle in the width direction, tighten the first locking bolt 41 back into the first threaded hole. This allows the two walls of the first through-hole 342 to move closer together under the action of the threaded clamping force between the first locking bolt 41 and the first threaded hole, switching the first through-hole 341 to the closed state. This allows the walls of the first through-hole 341 to fit against the outer circumference of the mounting post 31, achieving locking of the connecting post 32 and the air blower head 33.

[0055] like Figure 6As shown, specifically, the elastic connecting part 34 has two first elastic plates 343 protruding from their opposite upper surfaces along the height direction. The two first elastic plates 343 are arranged parallel to the width direction and spaced apart along the length direction, forming the first through-hole 342 between them. The corresponding positions of the two first elastic plates 343 form the first threaded hole along the length direction. With this configuration, when the first locking bolt 41 is loosened or unscrewed from the first threaded hole, the two first elastic plates 343 are more easily reset under their own elastic force, ensuring that the first through-hole 341 is switched to the expanded state to adjust the air blowing head 33 to rotate around the width direction to the required angle. When the first locking bolt 41 is tightened in the first threaded hole, the two first elastic plates 343 can be moved simultaneously towards each other, ensuring that the first through-hole 341 is accurately switched to the closed state to stably lock and fix the connecting post 32 and the air blowing head 33. As an alternative, the elastic connecting portion 34 has two first elastic plates 343 protruding from one end face along its length. The two first elastic plates 343 are arranged parallel to the width direction and spaced apart along the height direction, forming the first opening 342 between them. Corresponding positions of the two first elastic plates 343 penetrate along the height direction to form the first threaded hole. This alternative structure can also achieve the aforementioned technical effect.

[0056] like Figure 6As shown, in some embodiments of the present invention, the elastic connecting portion 34 has a third through hole 344 extending through the end opposite to the first through hole 342 in the height direction and through the length direction, through which the connecting post 32 passes; the elastic connecting portion 34 has a third through hole 345 communicating with the third through hole 344 at the end opposite to the first elastic plate 343 in the height direction, and the third through hole 345 extends through the elastic connecting portion 34 parallel to the length direction; third threaded holes are correspondingly provided on the two surrounding walls of the third through hole 345, and the third threaded holes are arranged parallel to the width direction. A third locking bolt 42 is connected to the internal thread of the three-threaded hole; the third through hole 344 has a closed state in which the third locking bolt 42 is tightened in the third threaded hole, causing the two walls of the third through hole 345 to approach each other, and an expanded state in which the third locking bolt 42 is loosened from the third threaded hole, causing the two walls of the third through hole 345 to move away from each other; when the third through hole 344 is in the closed state, the walls of the third through hole 344 clamp the connecting post 32; when the third through hole 344 is in the expanded state, the third through hole 344 and the connecting post 32 are in clearance fit. On the one hand, when the connecting post 32 is damaged and needs repair or replacement, the third locking bolt 42 can be loosened or unscrewed from the third threaded hole, switching the third through hole 344 to the expanded state, so that the connecting post 32 can be removed for repair or replacement, making the repair operation convenient. On the other hand, when it is necessary to adjust the air blowing head 33 to the required angle along its length according to the actual cleaning requirements, the third locking bolt 42 is first loosened or unscrewed from the third threaded hole, so that the two walls of the third through hole 345 move away from each other under the action of their own elastic restoring force, switching the third through hole 344 to the expanded state. At this time, the connecting post 32 can be rotated. The mounting post 31 and the elastic connecting part 34 are rotated around the length direction, thereby adjusting the air blowing head 33 to the required angle to meet different cleaning requirements and making it highly versatile. After the air blowing head 33 is rotated around the length direction to the required angle, the third locking bolt 42 is tightened in the third threaded hole, so that the two walls of the third through hole 345 are brought closer to each other under the action of the threaded clamping force between the third locking bolt 42 and the third threaded hole, switching the third through hole 344 to the closed state, so that the walls of the third through hole 344 fit against the outer circumference of the connecting post 32, thereby locking the connecting post 32 and the air blowing head 33.

[0057] like Figure 6As shown, specifically, the elastic connecting part 34 has two second elastic plates 346 protruding downwards from the end face opposite to the first elastic plate 343 along the height direction. The two second elastic plates 346 are arranged parallel to the length direction and spaced apart along the width direction, forming the third through-hole 345 between the two second elastic plates 346. The corresponding positions of the two second elastic plates 346 pass through to form the third threaded hole along the width direction. With this configuration, when the third locking bolt 42 is loosened or unscrewed from the third threaded hole, the two second elastic plates 346 are more easily reset under the action of their own elastic force, ensuring that the third through-hole 344 is switched to the expanded state, so as to adjust the air blowing head 33 to rotate around the length direction to the required angle or to remove the connecting column 32 for maintenance or replacement; when the third locking bolt 42 is tightened in the third threaded hole, the two second elastic plates 346 can be moved simultaneously in a direction closer to each other, ensuring that the third through-hole 344 is accurately switched to the closed state, so as to stably lock and fix the connecting column 32 and the air blowing head 33.

[0058] like Figure 4 , Figure 5 and Figure 7As shown, in some embodiments of the present invention, an elastic connecting seat 35 is provided between the air blowing head 33 and the connecting post 32. A second through hole 351 is formed through the elastic connecting seat 35 along its length direction, through which the connecting post 32 passes. The surrounding wall of the second through hole 351 is connected to a second opening 352, which extends through the elastic connecting seat 35 along its length direction and is located at the upper end of the elastic connecting seat 35 along its length direction. The two surrounding walls of the second opening 352 are correspondingly provided with second threaded holes, which are parallel to the thickness direction of the elastic connecting seat 35. The arrangement includes: the second locking assembly comprising a second locking bolt 51 that matches the second threaded hole; the second through hole 351 having a closed state in which the second locking bolt 51 is tightened in the second threaded hole, causing the two walls of the second through hole 352 to approach each other, and an expanded state in which the second locking bolt 51 is loosened from the second threaded hole, causing the two walls of the second through hole 352 to move away from each other; when the second through hole 351 is in the closed state, the walls of the second through hole 351 clamp the connecting post 32; when the second through hole 351 is in the expanded state, the second through hole 351 and the connecting post 32 are in clearance fit. When the air blower head 33 needs to be adjusted to the required angle along its length according to actual cleaning requirements, first loosen or unscrew the second locking bolt 51 from the second threaded hole. This allows the two walls of the second through-hole 352 to move away from each other under the action of their own elastic restoring force, switching the second through-hole 351 to the expanded state. At this time, the air blower head 33 can be rotated relative to the connecting post 32 along its length, thereby adjusting the air blower head 33 to the required angle along its length to meet different cleaning requirements and providing strong versatility. Simultaneously, after rotating the air blower head 33 to the required angle along its length, tighten the second locking bolt 51 back into the second threaded hole. This allows the two walls of the second through-hole 352 to move closer together under the action of the threaded clamping force between the second locking bolt 51 and the second threaded hole, switching the second through-hole 351 to the closed state. This allows the walls of the second through-hole 351 to fit against the outer circumference of the connecting post 32, thus locking the air blower head 33.

[0059] like Figure 7As shown, in some embodiments of the present invention, the elastic connecting seat 35 has a fourth through hole 353 formed through it along its thickness direction, through which the air blowing head 33 passes; the elastic connecting seat 35 has a fourth through hole 354 communicating with the fourth through hole 353 at one end opposite to the second through hole 352 along its length direction, and the fourth through hole 354 penetrates the elastic connecting seat 35 along its thickness direction; the two walls of the fourth through hole 354 are correspondingly provided with fourth threaded holes, which are arranged parallel to the length direction. The fourth threaded hole is internally threaded with a fourth locking bolt 52; the fourth through hole 353 has a closed state in which the fourth locking bolt 52 is tightened in the fourth threaded hole, causing the two walls of the fourth through hole 354 to approach each other, and an expanded state in which the fourth locking bolt 52 is loosened from the fourth threaded hole, causing the two walls of the fourth through hole 354 to move away from each other; when the fourth through hole 353 is in the closed state, the walls of the fourth through hole 353 clamp the air blowing head 33; when the fourth through hole 353 is in the expanded state, the fourth through hole 353 and the air blowing head 33 are in clearance fit. When the air blower head 33 is damaged and needs repair or replacement, the fourth locking bolt 52 can be loosened or unscrewed from the fourth threaded hole, causing the two walls of the fourth through hole 353 to move away from each other under their own elasticity, switching the fourth through hole 353 to the expanded state, so that the air blower head 33 can be removed for repair or replacement, making the repair operation convenient; at the same time, after the air blower head 33 is reinstalled in the fourth through hole 353, the fourth locking bolt 52 is tightened in the fourth threaded hole, causing the two walls of the fourth through hole 354 to move closer to each other under the action of the threaded clamping force between the fourth locking bolt 52 and the fourth threaded hole, switching the fourth through hole 353 to the closed state, so that the walls of the fourth through hole 353 fit against the outer circumference of the air blower head 33, thereby achieving the locking and fixing of the air blower head 33.

[0060] like Figures 1 to 4As shown, in some embodiments of the present invention, the cleaning chamber 11 is connected to a dust collection funnel 61 at its lower end face along the height direction, and a mesh 62 is detachably provided at the connection between the dust collection funnel 61 and the cleaning chamber 11; one side of the dust collection funnel 61 is connected to a dust collection box 63 through an exhaust pipe. By passing the gas used to clean the connector product through the dust collection funnel 61 and the dust collection box 63 in sequence for dust removal, the direct discharge of dust-containing gas to the outside environment is avoided, thus preventing impact on the working environment; at the same time, by detachably connecting the mesh 62 to the connection between the dust collection funnel 61 and the cleaning chamber 11, it is easy to remove the mesh 62 and clean the dust accumulated in the dust collection funnel 61. To facilitate the removal of the mesh 62, specifically, two handles 621 are provided on the upper end face of the mesh 62 along the height direction; the two handles 621 are arranged on both sides of the mesh 62 along the length direction.

[0061] like Figure 1 As shown, in some embodiments of the present invention, the air inlet of the air pump is connected to a compressed gas storage tank (not shown in the figure), and the air outlet of the air pump is connected to the air blowing head 33 through an air delivery pipe (not shown in the figure). A filter 71, a pressure reducing valve 72, and an oil mist lubricator 73 are sequentially arranged on the air delivery pipe along the flow direction of the compressed gas. Before being delivered to the air blowing head 33 by the air pump, the compressed gas passes through the filter 71, the pressure reducing valve 72, and the oil mist lubricator 73 for filtration, pressure reduction, and drying, and is finally blown onto the connector product to be cleaned, further improving the cleaning effect.

[0062] To prevent the filter 71, pressure reducing valve 72, and lubricator 73 from being exposed and easily damaged by external impacts, such as... Figure 1 As shown, in some embodiments of the present invention, the cleaning station 1 is provided with an installation groove 12 on the outer side wall of the opposite lower end along the height direction, and the filter 71, the pressure reducing valve 72 and the oil mist lubricator 73 are hidden and embedded in the installation groove 12.

[0063] like Figure 1 As shown, in some embodiments of the present invention, the cleaning equipment further includes a control switch electrically connected to the fresh air filter assembly and the air pump. The control switch is electrically connected to a timer, and the timer is electrically connected to an audible and visual indicator 13. The audible and visual indicator 13 is disposed on the outer wall of the cleaning station 1 and is located directly above the opening 111 in the height direction. When the fresh air filter assembly and the air pump are simultaneously activated by the control switch for cleaning operations, the timer also starts timing. When the cleaning operation time reaches the set value, a signal is transmitted to the audible and visual indicator 13, causing the indicator 13 to emit an sound to remind the operator that the cleaning operation is complete, so that the cleaned product can be removed and replaced with other products to be cleaned.

[0064] likeFigure 1 As shown, in some embodiments of the present invention, the cleaning station 1 is provided with a mounting cavity 14 at its lower end along the height direction. The mounting cavity 14 is provided with a power supply box 81 for supplying power to the cleaning equipment. The power supply box 81 can provide power from an external power source after voltage regulation before supplying it to the cleaning equipment, effectively preventing damage to the cleaning equipment due to excessive or insufficient current. Considering the large heat dissipation of the power supply box 81, to avoid the power supply box 81 working in a high-temperature environment for a long time, the service life of the power supply box 81 is extended. Specifically, a cooling fan 82 is provided on the side wall of the mounting cavity 14.
