DETAILED DESCRIPTION

[0030] In order to make the technical problems, technical solutions and beneficial effects of the present application more clear, the present application will be described in detail with reference to the drawings. The figure is a simplified schematic diagram, which only schematically illustrates the basic of the present application, thus only shows the relevant components of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0031] Please refer to Figures 1-9 , a hot air welding equipment 100 for automobile parts is provided, which comprises a carrier disc 10, a welding assembly 20, a moving module 30 and an adjusting assembly 40, and the carrier disc 10 is used for placing automobile parts 200.

[0032] The welding assembly 20 comprises a hot air generator 21, an air flow channel 22 communicated with the hot air generator 21, a welding rod 23 and a welding head 24 arranged at the outlet of the air flow channel 22, and the welding head 24 is provided with a plurality of air outlet holes 241 communicated with the air flow channel 22, the hot air generator 21 is used for generating hot air, and the welding head 24 is used for cooperating with the welding rod 23 to weld the automobile parts 200. Specifically, the hot air generator 21 is a prior art, and the specific structure is not described herein.

[0033] Further, the air flow channel 22 comprises a straight flow section one 221, a diffusion section 222 and a straight flow section two 223 arranged in sequence, the straight flow section one 221 is communicated with the outlet of the hot air generator 21, the inner diameter of the diffusion section 222 at the end far away from the air outlet hole 241 is smaller than the inner diameter of the diffusion section 222 at the end close to the air outlet hole 241, the straight flow section two 223 is communicated with the welding head 24, and the inner diameter of the straight flow section two 223 is larger than the inner diameter of the straight flow section one 221. After the air flow flows out of the outlet of the hot air generator 21, the air flow can be ensured to be relatively stable in speed and flow through the straight flow section one 221 with a constant diameter, so as to reduce the pulsation and turbulence of the air flow. Then the air flow is distributed in a larger range through the diffusion section 222 and flows into the straight flow section two 223. According to the continuity equation and Bernoulli equation, the setting of the diffusion section 222 can reduce the speed of the air flow, thereby reducing the noise generated when the air is exhausted.

[0034] Further, the outlet of the hot air generator 21 is provided with a flow uniformizing plate 211, a plurality of flow uniformizing holes 2111 are formed in the flow uniformizing plate 211, the flow uniformizing plate 211 is in a circular structure, and the diameters of the flow uniformizing holes 2111 gradually increase outward along the diameter of the flow uniformizing plate 211. Since the speed of the air flow in the peripheral region is usually higher and the speed of the air flow in the central region is lower when the air flow flows into the straight flow section one 221 from the outlet of the hot air generator 21, the air flow is not uniformly distributed. By gradually reducing the diameters of the flow uniformizing holes 2111 in the central region of the flow uniformizing plate 211, the air flow resistance in the central region of the flow uniformizing plate 211 can be increased, so that more air flow is forced to pass through the central region of the flow uniformizing plate 211, thereby realizing uniform distribution of the air flow.

[0035] Further, the straight flow section two 223 is provided with a flow dividing plate 2231, and a plurality of flow dividing holes 2232 are formed in the flow dividing plate 2231. The flow dividing plate 2231 is arranged to facilitate the uniform distribution of the air flow after the air flow is expanded in the diffusion section 222.

[0036] Further, the inner wall of the diffusion section 222 is provided with a plurality of air guiding protrusions 2221 arranged in sequence, the air guiding protrusions 2221 are in a spiral shape, and the diameters of the air guiding protrusions 2221 are matched with the inner diameter of the diffusion section 222. Due to the existence of the wall attachment effect, the air flow flows along the air guiding protrusions 2221 after entering the diffusion section 222 from the straight flow section one 221, the range of the air flow is gradually expanded to be matched with the straight flow section two 223, thereby facilitating the expansion of the air flow in the diffusion section 222.

[0037] The moving module 30 is used to drive the welding head 24 to move to correspond to the automobile part 200. Specifically, in the embodiment, the moving module 30 comprises a lead screw transmission mechanism 31 arranged along the length direction of the welding head 24 and a lifting cylinder 32 arranged along the height direction of the welding head 24, the output end of the lifting cylinder 32 is fixedly connected with the lead screw transmission mechanism 31, and the output end of the lead screw transmission mechanism 31 is fixedly connected with the hot air generator 21.
