DETAILED DESCRIPTION

[0025] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0026] Embodiment 1 Please refer to Figures 1 to 3 As shown, it shows the specific structure of the preferred embodiment of the present invention, which is an air-conditioning air intake grille welding tool.

[0027] When the air intake grille 16 is placed into the air intake tube 10, the welding seat 33 supports the air intake grille 16, and the welding seat 33 and the ultrasonic welding head 35 cooperate to press the welding position of the air intake grille 16 and the air intake tube 10 together. The pressure rod 41 presses the edge of the air intake grille 16 against the air intake tube 10, and the spring frame 42 presses the air intake grille 16 against the welding seat 33, which can well prevent the air intake grille 16 from deforming, and the fit is very tight, and the welding quality is more guaranteed.

[0028] The present application provides an air-conditioning air intake grille welding tool, comprising an air intake tube positioning mechanism 20, a welding mechanism 30, and an air intake grille positioning mechanism 40; the air intake tube positioning mechanism 20 comprises a positioning seat 21, a first positioning block 22 arranged around the positioning seat 21, and a suction cup 23 arranged on the positioning seat 21; the air intake tube 10 is placed on the positioning seat 21; the air intake grille positioning mechanism 40 comprises a pressure rod 41 and a spring frame 42; the pressure rod 41 and the spring frame 42 can move toward the positioning seat 21 and press the air intake grille 16; the welding mechanism 30 comprises a welding seat 33 and an ultrasonic welding head 35, the welding seat 33 is arranged on the positioning seat 21, the ultrasonic welding head 35 is arranged on one side of the welding seat 33, and the welding seat 33 and the ultrasonic welding head 35 can move toward each other and be pressed at the welding position. The preferred working steps are as follows: 1. The air inlet 10 is placed on the positioning seat 21. The first positioning block 22 limits the four sides of the air inlet 10 to ensure that the air inlet 10 will not loosen. The suction cup 23 sucks the air inlet 10, so that the entire air inlet 10 is fixed. 2. The air inlet grille 16 is placed into the air inlet 10. The welding seat 33 supports the air inlet grille 16 and presses the welding position of the air inlet grille 16 and the air inlet 10 together. Among them, the welding seat 33 is contoured and adapted to the air inlet grille 16. 3. The pressure rod 41 presses the edge of the air inlet grille 16 against the air inlet 10, and the spring frame 42 presses the air inlet grille 16 against the welding seat 33. This can well avoid deformation of the air inlet grille 16, and the welding fit is very tight. Among them, the spring frame 42 is elastic and has good buffering performance, which can avoid damaging the air intake grille 16. 4. The ultrasonic welding head 35 moves toward the welding seat 33, and the ultrasonic welding head 35 and the welding seat 33 together press the welding position, and then the ultrasonic welding head 35 moves so that the welding position of the air inlet tube 10 and the air intake grille 16 is completely pressed and welded together.

[0029] Preferably, a positioning column 24 is provided on the inner side of the positioning seat 21, and the positioning column 24 can be inserted into the air inlet 10; a sensor 25 is provided on the side of the positioning column 24 and on the outer side of the positioning seat 21 near the ultrasonic welding head 35. The positioning column 24 is contoured, and when the positioning column 24 is inserted into the air inlet 10, the position of the air inlet 10 can be further restricted to prevent it from loosening. The sensor 25 is preferably a photoelectric sensor 25, and the sensor 25 can determine the position of the air inlet 10 and the air inlet grille 16, as well as the movement position of the ultrasonic welding head 35. The air inlet 10 and the air inlet grille 16 are welded after they are completely in place, which is conducive to quality assurance.

[0030] Preferably, the welding seat 33 is connected to the output end of the first cylinder 32, and the first cylinder 32 drives the welding seat 33 to move back and forth; the welding seat 33 is connected to a limit hole 37, and a limit post 39 is provided beside the limit hole 37. The limit post 39 is connected to the output end of the second cylinder 38, and the second cylinder 38 drives the limit post 39 to insert into the limit hole 37. When the air intake grille 16 is put into the air intake duct 10, the first cylinder 32 drives the welding seat 33 to move toward the ultrasonic welding head 35. After the ultrasonic welding head 35 and the welding seat 33 press the air intake duct 10 and the air intake grille 16 together, the ultrasonic welding head 35 works, and then the two are welded together.

[0031] Preferably, the first cylinder 32 is arranged at the output end of the third cylinder 31, and the third cylinder 31 drives the first cylinder 32 to move up and down; a roughening plate 43 is arranged on the lower side of the welding seat 33, and a plurality of roughening needles 44 are arranged on the roughening plate 43, and the roughening plate 43 is arranged on the XYZ module, and the XYZ module drives the roughening plate 43 to move up and down, and press toward the inner welding position of the air inlet tube 10. The XYZ module is a cylinder-driven module. The XYZ module allows the roughening plate 43 to move in the XYZ direction. When the air inlet tube 10 is fixed on the positioning seat 21, the roughening plate 43 moves toward the inner wall of the air inlet tube 10 and moves up and down, so that the roughening needles 44 on the roughening plate 43 can roughen the inner wall of the air inlet tube 10. After the inner wall of the air inlet cylinder 10 is roughened, the roughened position of the air inlet cylinder 10 will absorb more energy, which can shorten the welding time between the air intake grille 16 and the air inlet cylinder 10 and help improve the welding efficiency.

[0032] Preferably, a positioning seam 34 is provided on the welding seat 33, and the reinforcing ribs on the air intake grille 16 can be embedded in the positioning seam 34. This design is conducive to positioning the air intake grille 16, thereby ensuring the position of the air intake grille 16 inside the air inlet tube 10 and ensuring the welding quality.

[0033] Preferably, the ultrasonic welding head 35 has several rows of welding needles 36, and the upper and lower rows of welding needles 36 are staggered. This design allows the welding points to be staggered, thereby improving the welding connection strength and ensuring the welding quality.

[0034] Preferably, the welding seat 33 and part of the first positioning block 22 are provided with air holes, which are connected to the air pipe and can blow cooling gas toward the welding position. The cooling gas can cool the welding position, which is more helpful to improve the production efficiency. At the same time, after the product is quickly cooled, it can also prevent loosening or displacement during demoulding.

[0035] Embodiment 2 Please refer to Figure 4-6 As shown, the present application provides an air inlet for an air conditioner, wherein the air inlet duct 10 and the air inlet grille 16 are welded together by using the air inlet grille welding tool described above, and a plurality of buckles 11 and mounting ears 12 are arranged on the wall plate of the air inlet duct 10; a grille is arranged on the air inlet grille 16, and a guide surface along the wind direction is arranged on the grille, and a water guide groove 13 is arranged on the lower edge of the air inlet grille 16, and a notch 14 is arranged on the water guide groove 13, and a drainage hole 15 at the bottom of the air inlet duct 10 is connected to a drainage pipe. The buckle 11 is used to buckle in a preset installation position. The mounting ear 12 is inserted with a screw for easy installation. The air inlet grille 16 is arranged at an angle, and when part of the water enters the air inlet grille 16, the water will flow along the air inlet grille 16 to the water guide groove 13, and then fall into the air inlet duct 10 at the notch 14 position, and the water will be discharged by connecting the drainage pipe, which can prevent water from entering the air conditioning system and help protect the air conditioning system.

[0036] Preferably, the grille includes a vertically intersecting linear grille 17 and a W-shaped grille 18, wherein the W-shaped grille 18 connects the longitudinal linear grilles 17, and the guide surface 110 is arranged on the W-shaped grille 18. The guide surface 110 is an arc surface or an inclined surface along the wind direction. This design reduces the air resistance when the air passes through the air intake grille 16, and also reduces the noise, which is more comfortable. The linear grilles 17 are arranged vertically and horizontally, and the linear grilles 17 cooperate with the W-shaped grille 18 to improve the anti-deformation ability of the air intake grille 16, so the air intake grille 16 can be made thinner and the cost is lower.

[0037] Preferably, the air intake grille 16 is provided with a hydrophobic coating, and the left and right sides of the air intake cylinder 10 are provided with T-shaped slots, into which the electrostatic dust removal grille 19 is inserted. The hydrophobic coating is a layered structure formed by a hydrophobic coating. The hydrophobic coating is provided on the air intake grille 16, which allows water droplets and the like to quickly fall into the water guide groove 13, thereby improving the ability to repel water, preventing water from entering the air-conditioning system, and improving the safety of the air-conditioning system. The slot is adapted to the installation edge of the electrostatic dust removal grille 19. The electrostatic dust removal grille 19 can improve the cleanliness of the incoming air without hindering the air flow, and there is no need to set a filter element, which is more energy-saving and environmentally friendly. When the electrostatic dust removal grille 19 needs to be cleaned, it is only necessary to pull out the electrostatic dust removal grille 19 for cleaning.

[0038] In summary, the design focus of the present invention is that the air inlet duct positioning mechanism 20, the welding mechanism 30, and the air inlet grille positioning mechanism 40 cooperate to prevent the air inlet grille 16 from deforming during welding, and the welding quality is more guaranteed and the welding efficiency is higher.

[0039] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
