Description

Technical Field

[0001] This utility model relates to the technical field of dust removal and cleaning equipment for sheet metal surfaces, specifically a non-contact vacuum cleaning machine. Background Technology

[0002] During the processing and production of PCB circuit boards, optical boards, and thin film boards, dust and debris can adhere to the surface of the boards. If not cleaned properly, subsequent processing steps can easily result in defects such as pressure marks, short circuits, and poor-quality finished products. Existing contact cleaning mechanisms rely on brush rollers to clean dust from the board surface. However, the brushes are prone to wear and tear, and direct contact with the board can easily scratch the surface of optical boards and thin film boards, causing product scrap.

[0003] The dust collection chamber of existing vacuum dust removal equipment is a fixed, non-removable internal structure. After dust accumulates inside the chamber, the equipment shell needs to be disassembled to clean the dust, which is cumbersome to maintain, results in long downtime for cleaning, and reduces the production line efficiency. At the same time, ordinary dust removal equipment lacks an electrostatic elimination mechanism. The boards have static electricity and will attract dust. Simply blowing air is not enough to completely remove the dust. Some equipment lacks board thickness detection and board feeding detection functions, and cannot be adapted to automated dust removal operations for boards of various thicknesses and specifications. Utility Model Content

[0004] The purpose of this invention is to provide a non-contact vacuum cleaner to solve the above-mentioned problems, such as the ease with which existing contact dust removal systems scratch the substrate, the cumbersome maintenance and disassembly of the suction chamber, the lack of static electricity elimination and substrate detection functions, and the poor dust removal effect.

[0005] This utility model achieves the above objectives through the following technical solution: a non-contact vacuum cleaning machine, comprising a main frame structure, an upper main structure, an upper component conveying and rotating structure, a lower component conveying and rotating structure, and a pull-out dust collection component; The upper part of the main body is installed inside the main frame structure, and the upper part of the main body is equipped with static elimination components, air blowing knife components and plate conveying components. The upper component conveying rotation structure and the lower component conveying rotation structure are assembled on the discharge side of the main frame structure to cooperate with the plate conveying component to complete the plate conveying; The pull-out dust collection component is slidably assembled on the discharge end of the main frame structure via a pull-out bottom tray pulley assembly. The pull-out dust collection component can be pulled out as a whole to collect the dust raised by the air blowing knife assembly.

[0006] Preferably, the static elimination component is a high-frequency ion air bar, which is arranged on the feed side of the equipment.

[0007] Preferably, the air-blowing knife assembly includes an upper air-blowing knife and a lower air-blowing knife, which are respectively arranged on the upper and lower sides of the plate conveying path.

[0008] Preferably, at least three sets of upper air-blowing knives and at least three sets of lower air-blowing knives are provided.

[0009] Preferably, the pull-out vacuuming assembly includes a stainless steel main body, a suction tube, a long slot, a suction tube interface, and a handle. The suction tube has a long slot for vacuuming, and the handle is located at the outer end of the pull-out vacuuming assembly.

[0010] Preferably, there are two sets of pull-out bottom tray pulley assemblies, which are respectively arranged on the left and right sides of the pull-out vacuum cleaner assembly tray.

[0011] Preferably, the sheet material conveying component includes a built-in conveying PU round belt and a sheet material infeed roller. The sheet material infeed roller is located at the equipment inlet and is used to guide the sheet material into the built-in conveying PU round belt.

[0012] Preferably, it also includes an active conveyor motor, which drives the built-in conveyor PU circular belt to rotate. The active conveyor motor is a stepper motor and is driven by a synchronous pulley and synchronous belt.

[0014] Preferably, the shell of the main frame structure is made of SUS304 mirror stainless steel.

[0015] The beneficial effects of this utility model are as follows: An independent electrostatic elimination component is set up to pre-eliminate static electricity from the board material, and then the air-blowing knife assembly non-contactly blows away dust from both sides of the board material, avoiding hard contact with the board surface throughout the process, effectively preventing scratches on optical and thin boards; the pull-out dust collection component can be pulled out as a whole by two sets of pull-out bottom tray pulley assemblies, eliminating the need to disassemble the entire machine housing when cleaning accumulated dust, simply pulling the handle to remove and clean the dust collection component, reducing maintenance difficulty and shortening downtime; the feeding end of the equipment can be equipped with a photoelectric sensor and a distance laser sensor, which can identify the board material arrival signal and board thickness, facilitating adaptive adjustment of process parameters; the entire machine can be connected to a production line to achieve continuous online dust removal of boards.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please Figures 1-4 As shown, this utility model provides a non-contact vacuum cleaning machine, including a main frame structure 1, an upper main structure 2, an upper component conveying and rotating structure 3, a lower component conveying and rotating structure 4, and a pull-out dust collection assembly 5. The upper main structure 2 is installed inside the main frame structure 1 and is equipped with an electrostatic elimination component 21, an air-blowing knife assembly 22, and a plate conveying component 23. The upper component conveying and rotating structure 3 and the lower component conveying and rotating structure 4 are assembled on the discharge side of the main frame structure 1 to cooperate with the plate conveying component 23 to complete the plate conveying. The pull-out dust collection assembly 5 is slidably assembled on the discharge end of the main frame structure 1 via a pull-out bottom tray pulley assembly 51. The pull-out dust collection assembly 5 can be pulled out as a whole to collect the dust raised by the air-blowing knife assembly 22. When the plate to be dusted is sent into the equipment, the electrostatic elimination component 21 eliminates static electricity, the air-blowing knife assembly 22 peels off the dust on the surface of the plate, and the dust is adsorbed and collected by the pull-out dust collection assembly 5, realizing non-contact dust removal of the plate.

[0020] Furthermore, the static electricity elimination component 21 is a high-frequency ion air bar, which is arranged on the feed side of the equipment. In actual use, the board passes through the high-frequency ion air bar, neutralizing the static electricity on the board surface and eliminating the phenomenon of static dust adsorption.

[0021] Furthermore, the air-blowing knife assembly 22 includes an upper air-blowing knife 221 and a lower air-blowing knife 222, which are respectively arranged on the upper and lower sides of the sheet material conveying path. At least three sets of upper air-blowing knives 221 and at least three sets of lower air-blowing knives 222 are provided. In actual use, the sheet material passes between the upper air-blowing knives 221 and the lower air-blowing knives 222, and the airflow from above and below sweeps the upper and lower surfaces of the sheet material, blowing away the attached dust from the surface of the sheet material.

[0022] Furthermore, the pull-out vacuum assembly 5 includes a stainless steel main body 52, a suction tube 53, a long slot 54, a suction tube interface 55, and a handle 56. The suction tube 53 has a long slot 54 for vacuuming, and the handle 56 is located at the outer end of the pull-out vacuum assembly 5. In actual use, a negative pressure generating device is connected to the suction tube interface 55, and the long slot 54 forms a negative pressure vacuuming area to collect the blown dust. During maintenance, the entire pull-out vacuum assembly 5 is pulled outward by holding the handle 56 to clean the suction tube 53 and the dust accumulated inside the cavity. After cleaning, it is pushed back into its original position.

[0023] Furthermore, there are two sets of pull-out bottom tray roller assemblies 51, which are respectively arranged on the left and right sides of the pull-out vacuum assembly 5 tray. In actual use, the two sets of pull-out bottom tray roller assemblies 51 together support the pull-out vacuum assembly 5 tray, ensuring smooth sliding during the pull-out process and preventing jamming.

[0024] Furthermore, the sheet material conveying component 23 includes a built-in conveyor PU round belt 231 and an infeed roller 232. The infeed roller 232 is located at the equipment inlet and is used to guide the sheet material into the built-in conveyor PU round belt 231. In actual use, the sheet material output from the upstream production line smoothly transitions to the built-in conveyor PU round belt 231 via the infeed roller 232, and the built-in conveyor PU round belt 231 drives the sheet material to move inside the equipment.

[0025] Furthermore, it also includes an active conveyor motor 24, which drives the built-in conveyor PU round belt 231. The active conveyor motor 24 is a stepper motor, and is driven by a synchronous pulley 241 and a synchronous belt 242. In actual use, the stepper motor, i.e., the active conveyor motor 24, drives the built-in conveyor PU round belt 231 through the synchronous pulley 241 and the synchronous belt 242, and the conveying speed can be adjusted according to the process.

[0026] Furthermore, a photoelectric sensor 6 and a distance laser sensor 7 are installed at the feed end of the equipment. The photoelectric sensor 6 is used to collect the board feeding position signal, and the distance laser sensor 7 is used to detect the board thickness. In actual use, the photoelectric sensor 6 detects the board position, and the distance laser sensor 7 obtains the board thickness data. The signal can be fed back to the equipment control system to adapt to the dust removal process of different boards.

[0027] Furthermore, the shell of the main frame structure 1 is made of SUS304 mirror stainless steel. In actual use, the mirror stainless steel shell is not prone to dust accumulation, is easy to wipe, is corrosion resistant, and is suitable for cleanroom conditions.

[0028] In use, the equipment is connected to a negative pressure air source and power supply. The upstream production line outputs a sheet material, which is then fed into the equipment's inlet. The sheet material first passes through the static elimination component 21, i.e., a high-frequency ion air bar, to eliminate surface static electricity. The sheet material is then driven by the sheet material conveying component 23 to continue moving forward, passing between the upper air blowing knife 221 and the lower air blowing knife 222. The airflow from both sides of the sheet material peels off and lifts the dust. The lifted dust is then negatively adsorbed and collected by the long slot 54 on the suction pipe 53 of the pull-out dust collection component 5. The sheet material continues to move forward and is sent out of the equipment via the upper component conveying rotating structure 3 and the lower component conveying rotating structure 4, flowing to the next process. After the equipment has been running for a period of time, the accumulated dust needs to be cleaned. After stopping the machine, the handle 56 of the pull-out dust collection component 5 is pulled out, and the entire component is pulled out by the two sets of pull-out bottom tray pulley components 51 to complete the internal dust cleaning. After cleaning, the component is pushed back to resume production.
