Description

Technical Field

[0001] The utility model relates to the technical field of air knives, in particular to an air knife dust removal mechanism. Background Technique

[0002] A PCB (Printed Circuit Board) is an important component of the electronics industry. Almost all electronic devices, from small electronic watches and calculators to large computers, communication electronic devices, and military weapon systems, use PCB boards. In the production process of PCB boards, a cleaning process is required for the PCB circuit boards, and the equipment commonly used to complete this process is the air knife dust removal equipment;

[0003] However, there are still certain deficiencies in the existing air knives. When the existing air knife equipment removes dust from the surface of the processed product, it is necessary to continuously adjust the wind direction. However, since the air knife removes dust by releasing high-pressure gas, it often has a relatively large reaction force itself. The existing air knife equipment often fixes and adjusts the direction of the air knife dust removal equipment through multiple groups of fixing bolts. However, adjusting the orientation of the air knife requires turning multiple bolts, which is rather cumbersome, and the fixing bolts will become loose after a long time of use, affecting the stability of the wind direction. Therefore, an air knife dust removal mechanism is proposed. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an air knife dust removal mechanism to solve the technical problem of cumbersome and difficult adjustment of the air knife orientation mentioned in the above background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: an air knife dust removal mechanism, including an air knife main body and an installation groove, adjustment components are symmetrically and rotatably installed on the inner walls of both the air knife main body and the installation groove, and a locking component is fixed to the outer wall of one end of the adjustment component;

[0006] The adjustment component includes two groups of rotating plates respectively rotatably connected to the inner walls on both sides of the installation groove. A diamond-shaped adjustment rod is rotatably installed at the middle position of the inner wall of the air knife main body. The axial centers of both ends of each group of rotating plates are fixed with a first rotating shaft, and the first rotating shaft penetrates through the outer wall of the air knife main body. The axial centers of both ends of the diamond-shaped adjustment rod are fixed with a second rotating shaft, and the second rotating shaft penetrates through the outer wall of the air knife main body. Turbines are fixed at the axial center positions of the outer walls of one ends of the first rotating shaft and the second rotating shaft, and worm gears are rotatably installed at the positions below the turbines on the outer wall of the air knife main body.

[0007] By adopting the above technical solution, first operate the locking component to release the fixation between the rotating plate and one end of the rhombic adjusting rod, and then rotate multiple groups of worm gears one by one. Drive the worm wheel, the rotating plate and the rhombic adjusting rod by the meshing of the worm gears to achieve rapid adjustment of the air outlet gap. At the same time, utilize the self-locking characteristic of the worm wheel and the worm gear to initially achieve fixation and prevent the rotating plate and the rhombic adjusting rod from being loosened by strong wind.

[0008] Further, the locking component includes an installation box fixed at the outer wall axis positions of the other ends of the first rotating shaft and the second rotating shaft. The installation box is of a hollow structure. A torsion rod is rotatably connected to the center of the surface of the installation box away from the adjusting component. An insertion hole is opened at an eccentric position on the outer wall of one end of the torsion rod close to the adjusting component.

[0009] By adopting the above technical solution, the torsion rod can conveniently drive the clamping rod to move up and down by the cooperation of the insertion hole and the insertion rod, so as to realize rapid fixation and release of the fixation of one end of the rotating plate and the rhombic adjusting rod.

[0010] Further, an insertion rod is inserted into the insertion hole. A clamping rod that slidably penetrates the inner wall of the installation box is fixed to the outer wall of one end of the insertion rod away from the torsion rod. A sleeve is fixed at the position where the inner wall of the installation box contacts the clamping rod.

[0011] By adopting the above technical solution, the sleeve can limit the clamping rod to ensure the stable and smooth movement of the clamping rod and the stable operation of the equipment.

[0012] Further, on the symmetrically arranged surfaces of the two rotating plates close to each other, buckling grooves that fit the outer wall of one end of the rhombic adjusting rod are opened, and rubber sealing strips are fixed in the buckling grooves. A turntable is fixed at the axis position of the outer wall of one end of each worm gear.

[0013] By adopting the above technical solution, the rubber sealing strips fixed in the buckling grooves can improve the airtightness and prevent air leakage on one side. A turntable or an internal hexagonal bolt hole is fixed at the axis position of the outer wall of one end of each worm gear, which can facilitate the adjustment of the rotation angle of the rotating plate and the rhombic adjusting rod, and further adjust the wind direction.

[0014] Further, sleeves concentric with the installation box are fixed to the outer walls at both ends of the air knife body. Multiple groups of clamping holes are equidistantly opened around the center of the inner wall of the sleeve, and the size of the sleeve matches the top end of the clamping rod.

[0015] By adopting the above technical solution, multiple groups of clamping holes can provide a fixing medium for the clamping rod to achieve enhanced fixation of the rotating plate and the rhombic adjusting rod.

[0016] Further, a rotating hole is opened at the position where the installation box contacts the torsion rod. The cross-sectional shape of the torsion rod is in the shape of the letter "T", and an annular rubber pad is fixed at the position where it contacts the surface of the installation box away from the adjusting component.

[0017] By adopting the above technical solution, an annular rubber pad is fixed at the contact position between the torsion bar and the surface of the mounting box away from the adjusting component, which can enhance the friction force and prevent the torsion bar from rotating self.

[0018] In summary, the present utility model mainly has the following beneficial effects:

[0019] The present utility model first operates the locking component to release the fixation between the rotating plate and one end of the rhombic adjusting rod, and then rotates multiple groups of worm gears one by one. By using the meshing of the worm gears to drive the worm wheels, as well as the rotating plate and the rhombic adjusting rod, the rapid adjustment of the air outlet gap is realized. At the same time, the self-locking characteristic of the worm wheel and the worm gear is used to initially realize the fixation and prevent the rotating plate and the rhombic adjusting rod from being loosened by a large wind force.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0029] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as a limitation to the present utility model.

[0030] The following will describe the embodiments according to the overall structure of the present utility model.

[0031] An air knife dust removal mechanism, as Figure 1 - Figure 8 shown, includes an air knife main body 1 and a mounting groove 11. Adjusting components 2 are symmetrically and rotatably installed on the inner walls of both the air knife main body 1 and the mounting groove 11. A locking component 3 is fixed to the outer wall of one end of the adjusting component 2;

[0032] The adjusting component 2 includes two groups of rotating plates 21 respectively rotatably connected to the inner walls on both sides of the mounting groove 11. A diamond-shaped adjusting rod 24 is rotatably installed at the middle position of the inner wall of the air knife main body 1. The two ends of each group of rotating plates 21 are fixed with first rotating shafts 211 at the axial center positions, and the first rotating shafts 211 penetrate through the outer wall of the air knife main body 1. The two ends of the diamond-shaped adjusting rod 24 are fixed with second rotating shafts 241 at the axial center positions, and the second rotating shafts 241 penetrate through the outer wall of the air knife main body 1. Turbines 22 are fixed at the axial center positions of the outer walls of one ends of the first rotating shafts 211 and the second rotating shafts 241. Worms 23 are rotatably installed at the positions below the turbines 22 on the outer wall of the air knife main body 1.

[0033] First, unlock the fixation of one end of the rotating plate 21 and the diamond-shaped adjusting rod 24 by operating the locking component 3, and then rotate multiple groups of worms 23 one by one. Drive the worm wheels, the rotating plates 21 and the diamond-shaped adjusting rod 24 by the meshing of the worms 23 to quickly adjust the gap of the air outlet. At the same time, the self-locking characteristic of the worm wheel and the worm 23 can be used to initially achieve fixation and prevent the rotating plate 21 and the diamond-shaped adjusting rod 24 from being loosened by a large wind force.

[0034] Please refer to Figure 5 - Figure 8 , the locking component 3 includes a mounting box 32 fixed at the axial center position of the outer wall of the other end of the first rotating shaft 211 and the second rotating shaft 241. The mounting box 32 is a hollow structure. A torsion rod 34 is rotatably connected to the center of the surface on one side of the mounting box 32 away from the adjusting component 2. An insertion hole 341 is opened at the eccentric position on the outer wall of the end of the torsion rod 34 close to the adjusting component 2.

[0035] The torsion rod 34 can be used to conveniently drive the clamping rod 33 to move up and down by the cooperation of the insertion hole 341 and the insertion rod 331, so as to quickly fix and release the fixation of one end of the rotating plate 21 and the diamond-shaped adjusting rod 24.

[0036] Please refer to Figure 5 - Figure 8, a plug rod 331 is inserted inside the jack 341. One end of the plug rod 331 away from the torsion rod 34 is fixed with a clamping rod 33 that slides through the inner wall of the mounting box 32. A sleeve 321 is fixed at the position where the inner wall of the mounting box 32 contacts the clamping rod 33.

[0037] The clamping rod 33 can be limited by the sleeve 321 to ensure the stable and smooth movement of the clamping rod 33 and the stable operation of the equipment.

[0038] Please refer to Figure 1 - Figure 4 , on the side surfaces of the two groups of rotating plates 21 close to each other, buckling grooves that fit the outer wall of one end of the diamond-shaped adjusting rod 24 are symmetrically opened, and rubber sealing strips are fixed in the buckling grooves. A turntable is fixed at the axial center position of the outer wall of one end of each group of worm gears 23.

[0039] The airtightness can be improved by fixing rubber sealing strips in the buckling grooves to prevent air leakage on one side. A turntable or an internal hexagonal bolt hole is fixed at the axial center position of the outer wall of one end of each group of worm gears 23, which can facilitate adjusting the rotation angles of the rotating plate 21 and the diamond-shaped adjusting rod 24, and then adjusting the wind direction.

[0040] Please refer to Figure 5 - Figure 8 , at both ends of the outer wall of the air knife body 1, sleeve rings 31 concentric with the mounting box 32 are fixed. A plurality of groups of clamping holes 311 are equidistantly opened around the center of the inner wall of the sleeve ring 31, and the size of the sleeve ring 31 matches the top end of the clamping rod 33.

[0041] The plurality of groups of clamping holes 311 can provide a fixing medium for the clamping rod 33 to realize the strengthening and fixing of the rotating plate 21 and the diamond-shaped adjusting rod 24.

[0042] Please refer to Figure 5 - Figure 8 , a rotating hole is opened at the position where the mounting box 32 contacts the torsion rod 34. The cross-sectional shape of the torsion rod 34 is in the shape of the letter "T", and an annular rubber pad is fixed at the position where it contacts the surface of the mounting box 32 away from the adjusting component 2.

[0043] The frictional force can be enhanced by fixing an annular rubber pad at the position where the torsion rod 34 contacts the surface of the mounting box 32 away from the adjusting component 2 to prevent the torsion rod 34 from rotating by itself.

[0044] The working principle of the present utility model is as follows: First, unlock the fixation of one end of the rotating plate 21 and the diamond-shaped adjusting rod 24 by operating the locking component 3, and then rotate each group of worm gears 23 one by one. Drive the worm wheel and the rotating plate 21 and the diamond-shaped adjusting rod 24 by the meshing of the worm gear 23 to realize the rapid adjustment of the air outlet gap. At the same time, the self-locking characteristic of the worm wheel and the worm gear 23 can be used to initially realize the fixation and prevent the rotating plate 21 and the diamond-shaped adjusting rod 24 from being loosened by a large wind force;

[0045] When locking the other ends of the rotating plate 21 and the diamond-shaped adjusting rod 24, it is first necessary to rotate the torsion rod 34 for one week. The groove on the surface of the torsion rod 34 is matched with the insertion rod 331, so as to drive the top end of the locking rod 33 to extend out of the sleeve 321 and insert into the corresponding jack 341, realizing the enhanced locking effect on the rotating plate 21 and one end of the diamond shape. To release the lock, the above operations can be reversed.
