Annular dust removal air knife for precision electronic carrier tape

Abstract

This application relates to annular dust removal air knives for precision electronic carrier tapes, belonging to the technical field of dust removal air knives. It includes a cover plate with a base plate at its bottom, and annular plates on the sides of the cover plate and base plate that are far apart. The beneficial effects of this application are that when a high-speed airflow is ejected from the outlet to remove oil, water stains, and impurities from the surface of the electronic carrier tape, the annular plates directly prevent impurities from spreading to the worktable. The adhesive tape and electromagnet ensure a stable connection between the protective ring, the cover plate, and the base plate, firmly confining impurities within the enclosed area. Furthermore, operators can disassemble the support frame by controlling the on / off state of the electromagnet, facilitating the replacement and maintenance of the protective ring and annular plates. This solves the cleaning problem caused by impurities scattering in existing technologies, reduces the extra workload for operators, avoids secondary pollution during the cleaning process, and significantly improves the cleanliness of the production environment.

Description

Technical Field

[0001] This application relates to the field of dust removal air knife technology, and in particular to annular dust removal air knife for precision electronic carrier tape. Background Technology

[0002] In the field of precision electronics manufacturing, electronic carrier tapes serve as the carrier and protective medium for micro-components such as chips and resistors. The cleanliness of their surface directly affects the packaging quality and product reliability. Therefore, it is necessary to remove surface dust, oil, and water stains through efficient dust removal equipment. Annular air knives, as devices that can generate strong and high-speed airflow, are widely used for cooling and surface cleaning of pipes, wires, extruded products, etc., due to their advantages such as high cleaning and drying efficiency and no contact damage. They also demonstrate important application value in the processing of precision electronic carrier tapes.

[0003] The annular air knife in related technologies usually consists of a base plate, a cover plate, and an air inlet pipe. The base plate and the cover plate are connected to form an air outlet. The gas is transported to the air outlet through the air inlet pipe and ejected at high speed to clean and dry the workpiece. However, existing annular air knives have obvious technical defects when performing dust and oil removal operations on precision electronic carrier tapes: due to the high wind speed, the oil stains, water stains, and impurities blown away by the high-pressure airflow are easily blown away directly and fall in large quantities on the worktable and surrounding areas. These scattered impurities are not only difficult to clean, increasing the extra workload of operators, but may also cause secondary pollution during the cleaning process, causing the carrier tape surface to be contaminated with dust again. Utility Model Content

[0004] In view of the above-mentioned problems existing in the prior art, the main objective of this application is to provide an annular dust removal air knife for precision electronic carrier tape.

[0005] The technical solution of this application is as follows: a ring-shaped dust removal air knife for precision electronic carrier tape, including a cover plate, a base plate at the bottom of the cover plate, and a ring plate on the side of the cover plate away from the base plate. Protective rings are fixedly connected to the side of the ring plate near the cover plate and the side near the base plate. Adhesive tape is provided on the outer periphery of the protective rings. The protective rings are adhered to the outer side of the cover plate and the base plate by the adhesive tape. Support frames are fixedly connected to both sides of the ring plate. Electromagnets for adsorbing the support frames are installed inside the cover plate and the base plate.

[0006] In a preferred embodiment, an air intake pipe is fixedly connected to one side of the base plate, an L-shaped connector is fixedly connected to the other side of the base plate, an adapter is fixedly connected to the end of the air intake pipe away from the base plate, and an air delivery hose is fixedly connected between the adapter and the L-shaped connector.

[0007] In a preferred embodiment, the cover plate and the bottom plate are provided with a sealing assembly, the sealing assembly including a sealing ring fixedly connected to the inner wall of the cover plate, and the bottom plate is provided with a sealing groove that cooperates with the sealing ring.

[0008] In a preferred embodiment, the cover plate has a plurality of locking bolts arranged at equal intervals, and the cover plate is connected to the base plate by the locking bolts.

[0009] In a preferred embodiment, the end of the adapter away from the gas delivery hose is fixedly connected to a connecting flange, and the end of the adapter near the connecting flange is provided with an air inlet.

[0010] In a preferred embodiment, the cover plate and the bottom plate have annular air vents inside, and the bottom plate has two chambers inside.

[0011] In a preferred embodiment, an airflow guide ring is fixedly connected inside the base plate and below the air outlet, the L-shaped connector is connected to the interior of one of the chambers, and the air inlet pipe is connected to the interior of the other chamber.

[0012] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0013] 1. In this application, when a high-speed airflow is ejected from the outlet to remove oil stains, water stains and impurities from the surface of the electronic carrier tape, the annular plate can directly block the impurities from spreading to the worktable. The setting of the adhesive tape and the electromagnet makes the protective ring form a stable connection with the cover plate and the bottom plate, firmly confining the impurities within the enclosure area. Moreover, the operator can disassemble the support frame by controlling the on and off of the electromagnet, which facilitates the replacement and maintenance of the protective ring and the annular plate. This solves the cleaning problem caused by the scattering of impurities in the prior art, reduces the extra workload of the operator, avoids secondary pollution during the cleaning process, and significantly improves the cleanliness of the production environment.

[0014] 2. In this application, the coordinated operation of the sealing groove and the sealing ring can effectively prevent gas leakage and ensure stable airflow pressure entering the chamber. Attached Figure Description

[0020] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0021] Reference Figure 1-4 A ring-shaped dust removal air knife for precision electronic carrier tape includes a cover plate 1, a base plate 2 at the bottom of the cover plate 1, and an annular plate 13 on the side of the cover plate 1 away from the base plate 2. Protective rings 14 are fixedly connected to the sides of the annular plates 13 near the cover plate 1 and near the base plate 2. Adhesive tape 15 is provided around the outer periphery of each protective ring 14, and the protective rings 14 are adhered to the outer sides of the cover plate 1 and the base plate 2 via the adhesive tape 15. Support frames 16 are fixedly connected to both sides of the annular plate 13. Electromagnets 3 for adsorbing the support frames 16 are installed inside the cover plate 1 and the base plate 2. By setting the annular plate 13 and protective rings 14 on the outer sides of the cover plate 1 and the base plate 2, an annular protective ring surrounding the air outlet 5 is constructed. The structure allows for the removal of oil, water stains, and impurities from the electronic carrier tape by a high-speed airflow exiting from the outlet 5. The annular plate 13 directly blocks the impurities from spreading to the worktable. The adhesive tape 15 and the electromagnet 3 ensure a stable connection between the protective ring 14, the cover plate 1, and the base plate 2, firmly confining the impurities within the enclosure area. Furthermore, operators can disassemble the support frame 16 by controlling the on / off state of the electromagnet 3, facilitating the replacement and maintenance of the protective ring 14 and the annular plate 13. This solves the cleaning problem caused by impurities scattering in the prior art, reduces the extra workload of operators, avoids secondary pollution during the cleaning process, and significantly improves the cleanliness of the production environment.

[0022] Specifically, an air inlet pipe 11 is fixedly connected to one side of the base plate 2, and an L-shaped connector 12 is fixedly connected to the other side of the base plate 2. An adapter 8 is fixedly connected to the end of the air inlet pipe 11 away from the base plate 2. An air supply hose 7 is fixedly connected between the adapter 8 and the L-shaped connector 12. The air inlet pipe 11 is connected to the L-shaped connector 12 via the adapter 8 and the air supply hose 7, realizing bidirectional airflow delivery to the chamber 17. After being guided by the airflow guide ring 6, it is evenly sprayed out from the air outlet 5, ensuring that the airflow on the surface of the electronic carrier tape is fully covered and the intensity is not significantly different, so as to reduce the cleaning dead zone problem caused by the uneven airflow of traditional air knives. The cover plate 1 and the base plate 2 are equipped with a sealing assembly. The sealing assembly includes a sealing ring 18 fixedly connected to the inner wall of the cover plate 1. The base plate 2 has a sealing groove 19 that cooperates with the sealing ring 18. Through the cooperation of the sealing groove 19 and the sealing ring 18, gas leakage can be effectively prevented and the airflow pressure entering the chamber 17 can be kept stable. The cover plate 1 is equipped with several locking bolts 4. The locking bolts 4 are arranged at equal intervals. The disassembly and assembly of the cover plate 1 and the base plate 2 can be completed by operating the locking bolts 4. The installation is simple and convenient. The cover plate 1 and the base plate 2 are connected by the locking bolts 4.

[0023] Specifically, the end of the adapter 8 away from the gas hose 7 is fixedly connected to a connecting flange 9, and the end of the adapter 8 near the connecting flange 9 is provided with an air inlet 10. The adapter 8 can be quickly connected to an external gas source through the connecting flange 9. The cover plate 1 and the bottom plate 2 have annular air outlets 5 inside. The bottom plate 2 has two chambers 17 inside. An airflow guide ring 6 is fixedly connected inside the bottom plate 2 and below the air outlet 5. The L-shaped connector 12 is connected to the inside of one of the chambers 17, and the air inlet pipe 11 is connected to the inside of the other chamber 17.

[0024] Working principle: First, the operator can connect the external air source to the adapter 8 via the connecting flange 9. Then, the electronic carrier belt is driven into the annular dust removal air knife. The air inlet pipe 11 is connected to the adapter 8, the air delivery hose 7 and the L-shaped connector 12 to realize bidirectional airflow to the chamber 17. After being guided by the airflow guide ring 6, it is evenly sprayed out from the air outlet 5 to ensure that the airflow covers the surface of the electronic carrier belt. This allows the annular plate 13 to directly block impurities from spreading to the workbench. The setting of the adhesive tape 15 and the electromagnet 3 makes the protective ring 14 form a stable connection with the cover plate 1 and the bottom plate 2, firmly confining the impurities within the enclosure area. At the same time, the operator can disassemble the support frame 16 by controlling the on and off of the electromagnet 3, which makes it convenient for the operator to replace and maintain the protective ring 14 and the annular plate 13. This solves the cleaning problem caused by the scattering of impurities in the existing technology, reduces the extra workload of the operator, and avoids secondary pollution during the cleaning process.
