Description

Technical Field

[0001] This invention relates to the field of ultrasonic cleaning technology, and specifically to a large-size double-sided dry ultrasonic cleaning head. Background Technology

[0002] Dry ultrasonic cleaning technology is a new type of dry cleaning technology that uses compressed air as the cleaning medium. Compressed air enters the cleaning head and then passes through a specific cavity structure (also called an ultrasonic generator) inside the cleaning head. At this time, high-frequency sound waves are generated due to the principle of cavity flow oscillation. After passing through the ultrasonic generator, the compressed air is ejected from the air outlet of the cleaning head. Under the combined action of the ejected gas and the sound waves, small dust particles on the surface of the workpiece can be cleaned.

[0003] Traditional wet cleaning machines require large amounts of purified water, chemical solvents, drying and cooling equipment, and subsequent wastewater treatment, resulting in significant equipment and consumable costs, high operating costs, and inconvenience. Other dry cleaning methods, such as air knives, have relatively large effective particle diameters, low cleaning rates, and no recovery of cleaning gases, failing to meet usage requirements. Existing dry ultrasonic cleaning heads can only perform single-sided cleaning. For double-sided cleaning, the general method is to first clean the front of the workpiece with the dry ultrasonic cleaning head, then use a flipping mechanism to turn the workpiece over, and finally clean the back of the workpiece. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a large-size double-sided dry ultrasonic cleaning head, which solves the problem that existing dry ultrasonic cleaning heads can only perform single-sided cleaning and cannot perform double-sided cleaning.

[0005] The above-mentioned technical objective of the present invention is achieved through the following technical solution:

A first opening and a second opening communicating with the negative pressure chamber are opened on one side of the air intake end plate. An air intake pipe above the channel is connected to the first opening, and an air outlet pipe above the channel is connected to the second opening. A third opening communicating with the negative pressure chamber is opened on one side of the air outlet end plate. A fourth opening is opened at the bottom of the second air intake chamber. An air outlet pipe below the channel communicates with the third opening, and an air intake pipe below the channel communicates with the fourth opening.

[0017] Preferably, the filter assembly includes top openings respectively formed at the top and bottom of the first air intake chamber and the second air intake chamber, and a filter is disposed in the top opening.

[0018] Preferably, the top and bottom of the first air intake chamber and the second air intake chamber are respectively connected to sealing end plates.

[0019] Preferably, a workpiece conveyor plate is connected to the top of the cleaning chamber located below the channel.

[0020] Preferably, the workpiece conveying plate includes a support plate, and a plurality of first rods and second rods are connected to the top of the support plate. The first rods and second rods are arranged adjacent to each other, and a plurality of driven rollers are connected to the first rods and the second rods. The first rods are longer than the second rods. The top of the support plate is provided with an air blowing port communicating with the positive pressure chamber, and the top of the support plate is also provided with a plurality of air suction ports communicating with the air suction slits.

[0021] Preferably, the support assembly includes two rib frames connected to the top of the profile bracket. Adjustment plates are respectively connected to both sides of the first air inlet chamber. Multiple connecting plates are connected between the two adjustment plates. Linear guide rails are provided on both sides inside the rib frame. The sliders on the linear guide rails are connected to the adjustment plates. A cylinder is connected to the top of the rib frame. The telescopic shaft of the cylinder is connected to the connecting plates. An outer cover is fitted over both the two adjustment plates and the connecting plates.

[0022] Preferably, the top of the profile bracket is connected to a plurality of first mounting plates and second mounting plates, the rib frame is connected to the first mounting plates, the top of the second mounting plates is connected to a support frame, and the lower cleaning head is connected to the support frame.

[0025] In summary, the present invention has the following main beneficial effects:

[0026] By setting up a profile support bracket, the entire device is supported. The air inlet pipe supplies compressed air to the positive pressure chamber and blows it onto the workpiece. The air outlet pipe draws air from the negative pressure chamber to provide negative pressure suction. The support component moves downwards, bringing the upper cleaning head closer to the workpiece. Compressed air enters the positive pressure chamber through the air inlet slit and is blown onto the workpiece by the ultrasonic generator for ultrasonic cleaning. After the compressed air cleans the workpiece surface, the compressed air and the dust particles it carries are recovered by the suction slit of the cleaning chamber, pass through the negative pressure chamber, and are recovered by the suction pipe. The filter assembly filters the first air inlet chamber. The compressed air in the second air intake chamber is filtered and purified to ensure that the cleanliness of the compressed air that ultimately acts on the workpiece surface exceeds the cleaning standard, preventing contamination of the workpiece. The supporting components allow the upper cleaning head to move up or down, bringing it closer to the workpiece during cleaning. After cleaning, the upper cleaning head returns to its original position, widening the channel between the upper and lower cleaning heads, allowing for manual cleaning of their surfaces. This solves the problem of existing dry ultrasonic cleaning heads not requiring a flipping mechanism or two separate cleaning zone-level transmission devices. This not only saves costs but also reduces the floor plan space required for the production line. Attached Figure Description

[0050] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0051] refer to Figures 1-16 A large-size double-sided cleaning dry ultrasonic cleaning head, comprising:

[0052] The profile support 100, the upper cleaning head 101 and the lower cleaning head 102 are provided. The lower cleaning head 102 is located on the top of the profile support 100, and the upper cleaning head 101 is located on the top of the lower cleaning head 102. There is a channel 103 between the upper cleaning head 101 and the lower cleaning head 102 for the workpiece to pass through.

[0053] The upper cleaning head 101 includes a first air inlet chamber 200, and a cleaning chamber 201 is provided at the bottom of the first air inlet chamber 200;

[0054] The lower cleaning head 102 includes a second air inlet chamber 202, and a cleaning chamber 201 is also provided at the top of the second air inlet chamber 202;

[0055] The cleaning chamber 201 includes two bent plates 203 and a rectangular plate 204. The bent plates 203 are located near the channel 103, and the rectangular plate 204 is located away from the channel 103. A positive pressure chamber 205 is formed between the two bent plates 203, and a negative pressure chamber 206 is formed inside the bent plates 203. An air intake slit 207 communicating with the negative pressure chamber 206 is opened on the side of the bent plates 203 near the channel 103. An air intake slit 208 communicating with the positive pressure chamber 205 is opened on one side of the rectangular plate 204. An air intake port 209 communicating with the air intake slit 208 is opened on the sides of the first air intake chamber 200 and the second air intake chamber 202 near the cleaning chamber 201, respectively.

[0056] An ultrasonic generator 210 is located inside a positive pressure chamber 205;

[0057] Among them, the two sides of the cleaning chamber 201 are respectively connected to the air outlet pipe 211 which communicates with the negative pressure chamber 206, and the two sides of the first air inlet chamber 200 and the bottom of the second air inlet chamber 202 are respectively connected to the air inlet pipe 212.

[0058] Two filter components are respectively located in the first air intake chamber 200 and the second air intake chamber 202, and are used to filter the air in the air intake chamber;

[0059] A support assembly is provided on the upper cleaning head 101 for moving the upper cleaning head 101 up and down.

[0060] The central axes of the upper cleaning head 101 and the lower cleaning head 102 have an angle of θ 104.

[0061] By setting up a profile bracket 100, which supports the entire device, compressed air can be supplied to the first air inlet chamber 200 and the second air inlet chamber 202 through the air inlet pipe 212 during use. The compressed air enters the positive pressure chamber 205 through the air inlet 209 and draws air from the negative pressure chamber 206 through the air outlet pipe 211. That is, the air inlet pipe 212 provides compressed air to the positive pressure chamber 205 and blows it onto the workpiece through the positive pressure chamber 205, while the air outlet pipe 211 draws air from the negative pressure chamber 206 to provide negative pressure suction for the negative pressure chamber 206. Specifically, the operator pushes the workpiece to be cleaned into the channel 103, and the workpiece is supported by the lower cleaning head 102. The upper cleaning head 101 is moved downwards and closer to the workpiece using the support component. Compressed air enters the positive pressure chamber 205 through the air inlet slit 208 and is blown onto the workpiece by the ultrasonic generator 210 for ultrasonic cleaning. The compressed air cleans the surface of the workpiece. After cleaning, the compressed air and the dust particles it carries are recovered by the suction slit 207 of the cleaning chamber 201, and then collected by the suction pipe after passing through the negative pressure chamber 206 within the cleaning chamber 201. The filter assembly filters and purifies the compressed air in the first air inlet chamber 200 and the second air inlet chamber 202, ensuring that the cleanliness of the compressed air that ultimately acts on the workpiece surface is greater than the cleaning standard and will not contaminate the workpiece. The support assembly can move the upper cleaning head 101 up or down to bring it closer to the workpiece during cleaning and clean its upper surface. After cleaning, the upper cleaning head 101 is reset upwards, widening the channel 103 between the upper cleaning head 101 and the lower cleaning head 102, allowing for manual cleaning of the surfaces of the upper and lower cleaning heads 101 and 102. This solves the problem that existing dry ultrasonic cleaning heads do not require a flipping mechanism or two cleaning area-level transmission devices. This not only saves costs but also saves space in the production line layout.

[0062] It is worth noting that in existing air knife cleaning technologies, compressed air is blown onto the workpiece surface after passing through the air knife. This has a good cleaning effect on larger dust particles, but the air knife lacks a gas recovery chamber, allowing the cleaned dust to easily escape into the environment and cause secondary contamination of the cleaned workpiece. For smaller dust particles, the cleaning efficiency of the air knife is relatively low. Compared to this method, the present invention provides a better cleaning effect and does not cause environmental pollution.

[0063] Existing wet cleaning methods require large amounts of pure water, chemical solvents, drying and cooling equipment, as well as subsequent wastewater treatment. Compared to this method, the present invention saves significant equipment costs and cleaning consumable expenses.

[0064] As a further embodiment of the present invention, an air intake end plate 300 and an air outlet end plate 301 are respectively connected to the sides of the first air intake chamber 200 and the second air intake chamber 202. One cleaning chamber 201 is connected to the air intake end plate 300, and the other cleaning chamber 201 is connected to the air outlet end plate 301. A first opening 302 and a second opening 303 communicating with the negative pressure chamber 206 are provided on one side of the air intake end plate 300. An air intake pipe 212 above the channel 103 is connected to the first opening 302, and an air outlet pipe 211 above the channel 103 is connected to the second opening 303. A third opening 304 communicating with the negative pressure chamber 206 is provided on one side of the air outlet end plate 301. A fourth opening 305 is provided at the bottom of the second air intake chamber 202. An air outlet pipe 211 below the channel 103 is connected to the third opening 304, and an air intake pipe 212 below the channel 103 is connected to the fourth opening 305.

[0065] By setting the air inlet end plate 300 and the air outlet end plate 301, the two cleaning chambers 201 can be connected to the first air inlet chamber 200 and the second air inlet chamber 202 respectively. The air inlet end plate 300 and the air outlet end plate 301 can also provide installation conditions for the air inlet pipe 212 and the air outlet pipe 211.

[0066] As a further embodiment of the present invention, the filter assembly includes a top opening 306 respectively opened at the top and bottom of the first air inlet chamber 200 and the second air inlet chamber 202, and a filter 307 is provided in the top opening 306.

[0067] By setting up filter 307, the compressed air passing through the first air inlet chamber 200 and the second air inlet chamber 202 can be purified to ensure that the cleanliness of the compressed air that finally acts on the surface of the workpiece is greater than the cleaning standard and will not contaminate the workpiece.

[0068] It is worth noting that the filter 307 in this embodiment is a plate-type high-efficiency filter, which is an integrated high-efficiency filter (plate-type) structure inside the upper cleaning head 101 and the lower cleaning head 102. Alternatively, a high-efficiency filter (barrel-type) structure can be installed on the air inlet pipe 212, or the high-efficiency filter (plate-type) can be installed at the end of the air inlet pipe 212 outside the cleaning head.

[0069] As a further embodiment of the present invention, the top and bottom of the first air intake chamber 200 and the second air intake chamber 202 are respectively connected to sealing end plates 308;

[0070] By setting a sealing end plate 308, which can be installed at the top opening 306 by detachable fasteners such as screws, the sealing end plate 308 can provide a seal for the top opening 306, preventing compressed air from being discharged from the top opening 306. At the same time, it can also facilitate the removal of the filter 307 for cleaning.

[0071] As a further embodiment of the present invention, a workpiece conveying plate 400 is connected to the top of the cleaning chamber 201 located below the channel 103.

[0072] By setting up a workpiece conveyor plate 400, the workpiece conveyor plate 400 can be connected to the workpiece roller conveyor line, saving the steps of handling workpieces.

[0073] As a further embodiment of the present invention, the workpiece conveying plate 400 includes a support plate 401. The top of the support plate 401 is connected to a plurality of first rods 402 and second rods 403. The first rods 402 and second rods 403 are arranged adjacent to each other. A plurality of driven rollers 404 are connected to the first rods 402 and second rods 403. The first rods 402 are longer than the second rods 403. The top of the support plate 401 is provided with an air blowing port 405 communicating with the positive pressure chamber 205. The top of the support plate 401 is also provided with a plurality of air suction ports 406 communicating with the air suction slots 207.

[0074] By setting a first rod 402 and a second rod 403 of different lengths, the roller conveyor line can be adapted. Specifically, the workpiece can flow on the driven roller 404 to pass through the channel 103. The driven roller 404 can lift the workpiece and the lower cleaning head 102 a certain distance, which can reduce the wear between the workpiece and the lower cleaning head 102. At the same time, it can also allow the compressed air in the positive pressure chamber 205 to be blown towards the workpiece through the air blowing port 405, and the air outlet pipe 211 to extract dust through the negative pressure chamber 206 and the air suction port 406.

[0075] As a further embodiment of the present invention, the support assembly includes two rib frame bodies 500 connected to the top of the profile bracket 100, adjusting plates 501 are respectively connected to both sides of the first air inlet chamber 200, and multiple connecting plates 502 are connected between the two adjusting plates 501. Linear guide rails 503 are provided on both sides inside the rib frame body 500, and the sliders on the linear guide rails 503 are connected to the adjusting plates 501. A cylinder 504 is connected to the top of the rib frame body 500, and the telescopic shaft of the cylinder 504 is connected to the connecting plates 502. An outer cover 505 is jointly fitted on the outside of the two adjusting plates 501 and the connecting plates 502.

[0076] By setting up cylinder 504 and controlling the extension and retraction of the telescopic shaft of cylinder 504, the adjusting plate 501 can drive the upper cleaning head 101 to move up and down. In this embodiment, cylinder 504 is used as the lifting power, but it can also be replaced by a servo motor plus ball screw structure as the lifting power.

[0077] The outer cover 505 can be bolted to the top of the connecting plate 502 to protect the upper structure of the upper cleaning head 101 and prevent dust from accumulating inside the upper cleaning head 101 and making it difficult to clean. Because of the high cleaning precision and efficiency of the ultrasonic cleaning head, the environment in which it is used has cleanliness requirements. Generally, a clean space is built using a fence, with an EFU installed at the top to blow clean gas downwards and a porous structure at the bottom to discharge gas. This also prevents the complex structure inside the upper cleaning head 101 from causing turbulence in the EFU airflow at the top of the device and affecting the cleanliness of the cleaning space.

[0078] As a further embodiment of the present invention, the top of the profile bracket 100 is connected to a plurality of first mounting plates 506 and second mounting plates 507, the rib frame 500 is connected to the first mounting plate 506, the top of the second mounting plate 507 is connected to a support frame 508, and the lower cleaning head 102 is connected to the support frame 508.

[0079] The support frame 508 can support the position of the lower cleaning head 102.

[0080] As a further embodiment of the present invention, side openings 509 are respectively provided on one side of the two adjusting plates 501 and on both sides of the support frame 508. Adjusting blocks 510 are provided in the side openings 509. Non-standard bolts 511 extending into the side openings 509 are rotatably connected to the top of the adjusting plates 501 and the top of the support frame 508, respectively. The non-standard bolts 511 are slidably connected to the adjusting blocks 510. Two adjusting nuts 512 are connected to the outer side wall of the non-standard bolts 511. The two adjusting nuts 512 are respectively located at the top and bottom of the adjusting blocks 510. The adjusting blocks 510 on the adjusting plates 501 are connected to the first air intake chamber 200, and the adjusting blocks 510 on the support frame 508 are connected to the second air intake chamber 202.

[0081] By setting the adjusting nut 512, the non-standard bolt 511, the adjusting nut 512, and the adjusting block 510 together form a fine-tuning mechanism that adjusts the up-and-down movement of the adjusting block 510 by adjusting the adjusting nut 512. By adjusting the height of the adjusting block 510 with multiple support points (3 or more sets of adjustment points), the flatness of the side of the upper cleaning head 101 and the lower cleaning head 102 that is close to the channel 103 can be adjusted. Since the upper cleaning head 101 and the lower cleaning head 102 are relatively long, if their deformation exceeds the allowable range, this fine-tuning mechanism is needed to adjust the flatness of the side of the upper cleaning head 101 and the lower cleaning head 102 that is close to the channel 103 to the allowable range.

[0082] As a further embodiment of the present invention, θ angle 104 is 5 degrees;

[0083] By setting angle θ 104, the upper cleaning head 101 and the lower cleaning head 102 are not completely parallel when installed on the profile bracket 100, but have a small included angle. With this setting, when the workpiece enters the channel 103 and leaves the channel 103, the entry side and the exit side of the workpiece are not parallel to the air intake slit 207 and the air inlet slit 208 on the two cleaning chambers 201. This can effectively reduce the vibration frequency and vibration amplitude of the workpiece caused by the airflow when the workpiece enters and leaves the channel 103.

[0084] It is worth noting that in this embodiment, θ angle 104 is 5 degrees, but θ angle 104 can also be 0 degrees, which does not affect the normal use of the device.

[0085] As a further embodiment of the present invention, the bottom of the profile bracket 100 is connected to casters 600 and foot cups 601.

[0086] By setting foot cups 601, foot cups 601 can be connected to profile brackets 100 by bolts or other fasteners. Profile brackets 100 support the main structure. Their length is ultimately affected by the cleaning width of the cleaning head, and their height is ultimately affected by the height of the material conveyor line connected to the cleaning head. Profile brackets 100 can be moved by casters 600, and after being moved into place, they can be fixed by foot cups 601.

[0087] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
