Description

Technical Field

[0001] This invention relates to the field of cleanroom vacuuming systems, and more particularly to a transparent cover-type cleanroom vacuuming system. Background Technology

[0002] A cleanroom, also known as a clean room, is a specially designed room that removes airborne particles, harmful gases, bacteria, and other pollutants from a defined space and controls the temperature, cleanliness, pressure, airflow speed and distribution, noise and vibration, lighting, and static electricity within a specific range.

[0003] Cleanrooms are commonly used in the production of electronic products. On conventional production lines, designated personnel work on specific processes. During these processes, electronic products release toxic and harmful gases. The cleanroom's air circulation and filtration system is usually insufficient to effectively remove these fumes from the workstations in a timely manner. Therefore, workers need to wear masks and other protective equipment, but this does not provide complete protection, and worker safety remains compromised. Summary of the Invention

[0004] This invention discloses a transparent cover-type cleanroom dust collection system, which aims to solve the technical problem that workers need to wear protective equipment such as masks while working, but such equipment cannot provide complete protection and the safety of workers is still not guaranteed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A transparent cover type cleanroom vacuum system includes a base, a conveyor belt on the base carrying multiple trays, a central support fixedly connected to the top center of the base, and multiple transparent covers fixed to the outer walls of the opposite sides of the central support. The transparent covers cover the trays, and through operating holes are provided on opposite sides of the transparent covers. The multiple transparent covers are symmetrically distributed around the central support according to the workstation positions. A diversion bend is tightly connected to the inner wall of the top of each transparent cover, and the multiple diversion bends are simultaneously connected to a main pipe. One end of the main pipe is connected to a negative pressure suction machine, and one end of the negative pressure suction machine is connected to a vent pipe. The vent pipe is connected to the ventilation system of the cleanroom. The main pipe is connected to the input end of the negative pressure suction machine, and the vent pipe is connected to the output end of the negative pressure suction machine.

[0007] Cleanrooms, equipped with negative pressure suction fans and transparent hoods, are commonly used in the production of electronic products. During the production process, electronic products release toxic and harmful gases. The cleanroom's air circulation and filtration system is usually insufficient to remove the exhaust gases from the workstations in a timely and effective manner. By equipping each workstation with an independent transparent hood, and using negative pressure suction fans to extract the exhaust gases generated during operation through the main pipe and branch pipes, the effective shielding of the transparent hoods can minimize the leakage of exhaust gases. This allows the gases to smoothly enter the ventilation system for treatment and discharge through the branch pipes and main pipe, thereby effectively protecting the workers.

[0008] In a preferred embodiment, the cleaning mechanism includes a diversion hose, which is fixed to one inner wall of the transparent cover and tightly connected to a hemispherical vent pipe. Multiple air jets are evenly spaced on one inner wall of the hemispherical vent pipe. Support shafts are fixedly connected to the opposite outer walls of the hemispherical vent pipe, and second bearing seats are respectively provided on the two support shafts. One end of one support shaft is connected to a second stepper motor via a right-angle coupling. An air supply bend is tightly connected to one inner wall of the diversion hose, and multiple air supply bends on the multiple transparent covers are simultaneously connected to an air supply system. The air supply system includes a first air supply channel and a second air supply channel, with the air supply volume of the first air supply channel being greater than that of the second air supply channel.

[0009] With a cleaning mechanism in place, before operation, as the electronic product enters the transparent enclosure via a conveyor belt, the second stepper motor drives the entire hemispherical ventilation pipe to rotate through a right-angle coupling. This causes multiple jet nozzles connected to the first air supply channel to sweep the surface of the electronic product with a higher jet pressure, thereby removing some dust that may be adhering to the surface of the electronic product and sucking it in through the diversion bend. This ensures the cleanliness of the electronic product surface and makes it easier to maintain the cleanroom environment. In addition, after cleaning, the second air supply channel is switched to deliver air stably with a lower jet pressure, which guides the exhaust gas into the diversion bend, thus ensuring the thoroughness of exhaust gas intake.

[0010] In a preferred embodiment, the sealing mechanism includes a bracket and the bracket includes two insert plates. Each transparent cover has a slot fixedly connected to its operating hole, and the two insert plates are respectively inserted into the slots to cover the outside of the operating hole. The top outer wall of each bracket is fixedly connected to a slide, and the slide is movably sleeved on a light bar. Multiple light bars are simultaneously fixed on a central support, and the top of the multiple light bars is simultaneously fixedly connected to a bracket. The top outer wall of the slides arranged in the same direction is simultaneously fixedly connected to a fixed frame, and the center position of each fixed frame is fixedly connected to a nut slide. The nut slide is movably sleeved and engaged with the outer wall of a lead screw. The bottom end of the lead screw is connected to a first bearing seat. The top ends of the two lead screws are respectively fixedly connected to a first gear, and the two first gears are respectively connected to the top of the bracket through bearings. The outer walls of the two first gears are simultaneously engaged with a second gear, and the second gear is connected to a first stepper motor.

[0011] With a closed mechanism, when the cleaning mechanism is cleaning, the first step motor drives the second gear to rotate, and through the meshing of the two first gears, it drives the two lead screws to rotate. Under the action of the fixed frame, multiple inserts move down the light bar until the insert plates on both sides are inserted into the slots and cover the outside of the through operation hole, thus preventing dust from being sprayed out of the operation hole during the cleaning process and ensuring thorough dust adsorption.

[0012] As described above, a transparent cover type cleanroom vacuum system includes a base, on which a conveyor belt is provided and multiple trays are conveyed. A central support is fixedly connected to the top center of the base, and multiple transparent covers are fixed to the outer walls of the opposite sides of the central support. The transparent covers cover the trays, and through operating holes are provided on the opposite sides of the transparent covers. The multiple transparent covers are symmetrically distributed with the central support as the center according to the workstation position. A diversion bend is tightly connected to the top inner wall of each transparent cover, and multiple diversion bends are simultaneously connected to a main pipe. One end of the main pipe is connected to a negative pressure suction machine, and one end of the negative pressure suction machine is connected to a vent pipe. The vent pipe is connected to the ventilation system of the cleanroom. The main pipe is connected to the input end of the negative pressure suction machine, and the vent pipe is connected to the output end of the negative pressure suction machine.

[0013] As can be seen from the above, the transparent cover-type cleanroom dust collection system provided by the present invention has the technical effect of ensuring effective adsorption of exhaust gas and effectively protecting workers. Attached Figure Description

[0024] Reference Figure 5 In a preferred embodiment, a gas supply bend 802 is tightly connected to one inner wall of the diversion hose 801, and multiple gas supply bends 802 on multiple transparent covers 7 are simultaneously connected to a gas supply system 9. The gas supply system 9 includes a first gas supply channel and a second gas supply channel, and the gas supply volume of the first gas supply channel is greater than the gas supply volume of the second gas supply channel.

[0025] Reference Figure 2 and Figure 3 In a preferred embodiment, the sealing mechanism 5 includes a bracket 506, and the bracket 506 includes two insert plates 507. Each transparent cover 7 has a slot 514 fixedly connected to its operation hole 14, and the two insert plates 507 are respectively inserted into the slots 514 and cover the outside of the operation hole 14.

[0028] Reference Figure 4In a preferred embodiment, the top ends of the two lead screws 510 are respectively fixedly connected to the first gear 511, and the two first gears 511 are respectively connected to the top end of the bracket 502 through bearings 512.

[0029] Working principle of the invention:

[0030] Before operation, when the electronic product enters the transparent cover 7 via the conveyor belt 12, the second stepper motor 804 drives the entire hemispherical ventilation pipe 805 to rotate through the right-angle coupling 803, so that multiple jet nozzles 806 are connected to the first air supply channel to sweep the surface of the electronic product with a large jet pressure, thereby removing some of the dust that may be adhering to the surface of the electronic product and sucking it in along the diversion bend pipe 6. This ensures the cleanliness of the electronic product surface and makes it easier to maintain the cleanroom environment.

[0031] When the cleaning mechanism 8 is cleaning, the first step motor 501 drives the second gear 513 to rotate, and through meshing with the two first gears 511, it drives the two lead screws 510 to rotate. Under the action of the fixed frame 505, multiple inserts 506 move down along the light bar 503 until the insert plates 507 located on both sides are inserted into the slots 514 and cover the outside of the through operation hole 14, thereby preventing dust from being sprayed out from the operation hole 14 during the cleaning process and ensuring thorough dust adsorption.

[0032] During operation, each workstation is equipped with an independent transparent cover 7, and operation holes 14 are opened on both sides of the transparent cover 7 for operation. This allows hands to pass through the operation holes 14 to perform processing operations inside the transparent cover 7. The negative pressure suction machine 3 then extracts the exhaust gas generated during operation through the main pipe 4 and the diversion bend 6. Under the effective shielding of the transparent cover 7, the leakage of exhaust gas can be avoided to a large extent, allowing it to smoothly enter the ventilation system for treatment and discharge through the diversion bend 6 and the main pipe 4, thereby achieving effective protection for workers.

[0033] In addition, after cleaning is completed, the second air supply channel is switched to deliver air stably with a smaller jet pressure, which can guide the exhaust gas into the diversion bend 6, thereby ensuring the thorough intake of exhaust gas.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
