Description

Technical Field

[0001] This utility model relates to the field of dust removal and cleaning technology, specifically to a novel fully automatic non-contact return cleaning device. Background Technology

[0002] During transportation and storage after production, PCB boards accumulate dust on their surfaces, which has a significant impact on their performance. Furthermore, static electricity often forms on the PCB surface due to contact and friction. This static electricity attracts fine particles such as dust to the PCB surface, making it impossible to perform semiconductor processing techniques such as photolithography and etching. Electrostatic discharge can also cause safety accidents. Therefore, dust removal machines are often used to clean the surface of PCB boards.

[0003] Currently, existing dust collectors typically use brushes to clean products, resulting in only moderate cleaning effectiveness. Furthermore, ordinary contact cleaning methods are ineffective for surfaces with fine structures or irregular shapes. In addition, existing dust collectors only clean raw material boards before production, neglecting the cleaning needs of finished product boards. After assembly and testing, finished boards may generate new floating dust and static electricity particles due to handling, and existing dust collectors cannot perform secondary cleaning on these boards. This leads to potential cleanliness issues before the finished products leave the factory, requiring additional independent cleaning equipment, increasing the complexity and cost of the production process. Utility Model Content

[0036] To make the technical problem to be solved, the technical solution, and the 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 noted that similar reference numerals and letters in the following drawings indicate similar items; therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings. It is also declared that the embodiments described below are only for explaining this utility model and are not intended to limit this utility model.

[0037] It should be noted that the terms "installation," "setting," "connection," and "fixing" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly defined. Indications of orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use, or the orientation or positional relationship commonly understood by those skilled in the art. They are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. The terms "first" and "second" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features.

[0038] Please see Figures 1 to 4This utility model provides a novel fully automatic non-contact return cleaning device, including a frame 1 and a dustproof cover 2 covering the frame 1. The frame 1 is equipped with a raw material cleaning mechanism 3 and a finished product return cleaning mechanism 4. The raw material cleaning mechanism 3 includes a raw material conveying track 31 for receiving and outputting a fixture carrying a raw material plate, an electrostatic elimination component 32 disposed below the input end of the raw material conveying track 31, a tornado cleaning component 33 disposed above the dust removal station of the raw material conveying track 31, and an ultrasonic cleaning component 34 disposed below the dust removal station of the raw material conveying track 31. The dustproof cover 2 has a first inlet 21 and a first outlet 22 respectively corresponding to the input end and output end of the raw material conveying track 31. The finished product return cleaning mechanism 4 includes a finished product return track 41 for receiving and outputting a fixture carrying finished product plates, a brush cleaning assembly 42 disposed above the input end of the finished product return track 41, and an air knife cleaning assembly 43 disposed above the output end of the finished product return track 41. The dust cover 2 is provided with a second inlet 23 and a second outlet 24 at the positions corresponding to the input end and the output end of the finished product return track 41, respectively.

[0039] Workflow: When the fixture carrying the raw material board enters the raw material conveying track 31, the static elimination component 32 eliminates the static electricity on the raw material board to prevent dust accumulation after subsequent cleaning. After the raw material conveying track 31 transports the fixture carrying the raw material board to the dust removal station, the upper tornado cleaning component 33 starts to rotate at high speed and sprays out high-speed airflow, forming a swirling airflow like a tornado. At the same time, the lower ultrasonic cleaning component 34 starts to clean the surface of the raw material board. After cleaning, the raw material conveying track 31 outputs the fixture carrying the raw material board to the subsequent production process. After the finished product board is produced, it flows back to the finished product return track 41 through the fixture. During the transmission process, the brush cleaning component 42 and the air knife cleaning component 43 perform secondary cleaning on the finished product board after production.

[0040] In this embodiment, the raw material cleaning mechanism 3 is equipped with a tornado cleaning component 33 and an ultrasonic cleaning component 34 above and below the dust removal station of the raw material conveying track 31, respectively. By utilizing the synergistic effect of the tornado and ultrasound, it can avoid contact with the surface of the raw material board while efficiently cleaning the surface of the product. By adding a finished product return cleaning mechanism 4, the finished product board is cleaned a second time. It can also be connected with other machines (such as finished product testing equipment and finished product recycling equipment) to achieve integrated processing. This ensures that the raw materials are clean when they enter and the finished products are clean when they leave. There is no need for manual transfer to independent equipment. This not only eliminates the cleanliness risks of the finished products before they leave the factory, but also reduces the production process steps and lowers the equipment investment cost and operation complexity.

[0041] Please see Figure 4 , Figure 5In one embodiment, a pressure net 35 is provided between the raw material conveying track 31 and the tornado cleaning component 33. A lifting and pressing component 36 is provided below the dust removal station on the raw material conveying track 31. The lifting and pressing component 36 is used to lift the fixture carrying the raw material plate on the dust removal station to press it firmly against the pressure net 35. Because the tornado cleaning component 33 generates a high-speed swirling airflow during operation, if the fixture is not fixed, it is easily deflected by the airflow. If the fixture is blown off course during cleaning, it will deviate from the preset path of the raw material conveying track 31, and may get stuck in the track during subsequent transport, requiring manual shutdown and adjustment, severely affecting production efficiency. Through the cooperation between the pressure net 35 and the lifting and pressing component 36, the fixture can maintain a fixed posture throughout the cleaning process, preventing it from being blown off course.

[0042] Please see Figure 4 , Figure 6 In one embodiment, a first protective cover 37 is provided around the material conveying track 31 and the pressure net 35. Since the tornado cleaning component 33 tends to spread dust when cleaning the surface of the material board, without the first protective cover 37, the spread dust may fall back onto the cleaned surface of the material board or contaminate surrounding equipment components, causing secondary pollution. The first protective cover 37 encloses the area of ​​the material conveying track 31 and the pressure net 35, forming a relatively closed cleaning space. This ensures that the dust is always confined inside the first protective cover 37 and ultimately collected by a dust collection device, effectively cutting off the dust diffusion path and ensuring the cleanliness of the material board after cleaning.

[0043] Please see Figure 7 , Figure 8 In one embodiment, the tornado cleaning assembly 33 includes a dust suction hood 331 with a lower opening, a tornado nozzle 332 disposed inside the dust suction hood 331 and blowing air upwards, and a first moving module 333 for driving the dust suction hood 331 and the tornado nozzle 332 to move back and forth along the length of the raw material conveying track 31. The first moving module 333 is fixed on the frame 1, and the dust suction hood 331 is fixed on the moving end of the first moving module 333. The dust suction hood 331 is connected to an external dust suction device through a first suction pipe 3311. In this embodiment, the dust suction hood 331 is connected to the external dust suction device through the first suction pipe 3311. While the tornado nozzle 332 sprays high-speed airflow to blow up dust, the dust suction hood 331 simultaneously generates negative pressure, directly sucking the blown dust into the suction pipe, realizing simultaneous blowing and suction, greatly improving the dust collection rate, and fundamentally avoiding cleaning failure caused by dust backflow. The first moving module 333 can drive the tornado nozzle 332 to automatically adapt to the length of the raw material plate, achieving full coverage cleaning from one end of the raw material plate to the other without adjusting the position of the raw material plate. This adapts to the cleaning needs of various specifications of raw material plates and improves the versatility of the equipment.

[0044] Please see Figure 7 , Figure 8 In one embodiment, a height adjustment component 334 is provided between the moving end of the first moving module 333 and the dust collection hood 331 for adjusting the height of the dust collection hood 331 and the tornado nozzle 332. Since different raw material boards and their corresponding fixtures have varying thicknesses, if the heights of the dust collection hood 331 and the tornado nozzle 332 are fixed, for thicker raw material boards and fixtures, the tornado nozzle 332 may be too close to the board, resulting in excessive airflow impact and damage to the board; for thinner raw material boards and fixtures, the tornado nozzle 332 may be too far away, resulting in insufficient airflow intensity and reduced cleaning effect. The height adjustment component 334 allows the height of the dust collection hood 331 and the nozzle to be adjusted according to the thickness of the raw material board and fixture, ensuring that the tornado nozzle 332 maintains the optimal distance from the surface of the raw material board, allowing the equipment to adapt to raw material boards and fixtures of different thicknesses.

[0045] Please see Figure 9 In one embodiment, the ultrasonic cleaning assembly 34 includes an upward-emitting USC ultrasonic generator head 341 and a second moving module 342 for driving the USC ultrasonic generator head 341 to move back and forth along the width direction of the raw material conveying track 31. The second moving module 342 is fixed to the frame 1, and the USC ultrasonic generator head 341 is fixed to the moving end of the second moving module 342 and extends into the interior of the raw material conveying track 31. The USC ultrasonic generator head 341 utilizes the principle of ultrasonic vibration to more effectively remove stubborn dust and stains adhering to the surface of the raw material plate. During dust removal, the second moving module 342 drives the USC ultrasonic generator head 341 to reciprocate along the width direction of the raw material conveying track 31 to remove dust, ensuring that all areas of the raw material plate surface are thoroughly cleaned. The ultrasonic cleaning assembly 34 and the tornado cleaning assembly 33 cooperate to form a comprehensive cleaning system, which can significantly improve the cleaning effect and efficiency.

[0046] Please see Figure 4 , Figure 10 In one embodiment, a second protective cover 44 is provided around the finished product return track 41, and a second suction pipe 441 connected to an external dust collection device is provided on the top of the second protective cover 44. During the cleaning process of the finished product return cleaning mechanism 4, the brush cleaning component 42 and the air knife cleaning component 43 will remove the dust attached to the surface of the finished product board; if no protective structure is provided, this stripped dust will diffuse with the airflow to other areas inside the equipment, or even be re-adsorbed onto the surface of the finished product board that has been cleaned, resulting in secondary pollution problems. The second protective cover 44 encloses the finished product return track 41 to form a relatively closed cleaning space, so that the dust is always confined inside the second protective cover 44 and finally collected in a unified manner by the cooperation of the second suction pipe 441 and the dust collection device, which can effectively cut off the dust diffusion path and ensure the cleanliness of the finished product board after cleaning.

[0047] Please see Figure 4 In one embodiment, the raw material cleaning mechanism 3 further includes a first inlet dust collection mechanism 38 and a first outlet dust collection mechanism 39, which are respectively located above the input and output ends of the raw material conveying track 31. During the cleaning process, the first inlet dust collection mechanism 21 and the first outlet dust collection mechanism 22 block the first inlet 21 and the first outlet 22 of the dustproof cover 2, thereby collecting dust while preventing dust leakage. After dust removal, the first inlet dust collection mechanism 21 and the first outlet dust collection mechanism 22 reopen the first inlet 21 and the first outlet 22 of the dustproof cover 2, allowing the fixture carrying the raw material plate to freely enter and exit the equipment.

[0048] Please see Figure 11 In one embodiment, the first inlet suction mechanism 38 includes an inlet suction head 381 and an inlet sealing cylinder 382 for moving the inlet suction head 381 up and down to block the first inlet 21. The inlet sealing cylinder 382 is fixed on the frame 1, and the inlet suction head 381 is fixed on the telescopic end of the inlet sealing cylinder 382. An inlet sealing plate 383 is provided on the side of the inlet suction head 381 near the first inlet 21. The first outlet suction mechanism 39 includes an outlet suction head 391 and an outlet sealing cylinder 392 for moving the outlet suction head 391 up and down to block the first outlet 22. The outlet sealing cylinder 392 is fixed on the frame 1, and the outlet suction head 391 is fixed on the telescopic end of the outlet sealing cylinder 392. An outlet sealing plate 393 is provided on the side of the outlet suction head 391 near the first outlet 22. When the raw material cleaning mechanism 3 is cleaning, the inlet sealing cylinder 382 and the outlet sealing cylinder 392 extend the inlet dust collection head and the outlet dust collection head respectively, so that the inlet sealing plate 383 and the outlet sealing plate 393 seal the first inlet 21 and the first outlet 22 of the dustproof cover 2, thereby collecting dust and preventing dust leakage.

[0049] Please see Figure 4 In one embodiment, the finished product return cleaning mechanism 4 further includes a second inlet dust collection mechanism 45 and a second outlet dust collection mechanism 46, which are respectively located above the input and output ends of the finished product return track 41. During the cleaning process, the second inlet dust collection mechanism 23 and the second outlet dust collection mechanism 24 block the second inlet 23 and the second outlet 24 of the dustproof cover 2, thereby collecting dust while preventing dust leakage. After dust removal, the second inlet dust collection mechanism 23 and the second outlet dust collection mechanism 24 reopen the second inlet 23 and the second outlet 24 of the dustproof cover 2, allowing the fixture carrying the finished product plate to freely enter and exit the equipment.

[0050] It should be noted that since the specific structure and working principle of the second inlet suction mechanism 45 and the second outlet suction mechanism 46 are similar to those of the first inlet suction mechanism 38 and the first outlet suction mechanism 39, this utility model will not repeat the description.

[0051] It should be understood that those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.

[0052] The present utility model patent has been described above with reference to the accompanying drawings. Obviously, the implementation of the present utility model patent is not limited to the above-described manner. Any improvements made by adopting the inventive concept and technical solution of the present utility model patent, or the direct application of the inventive concept and technical solution of the present utility model patent to other occasions without modification, are all within the protection scope of the present utility model.
