DETAILED DESCRIPTION

[0021] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0022] Reference Figure 1 As shown, an automatic assembly machine for the air outlet blades of an automobile air conditioner comprises a base 1 for supporting the assembly machine body; a support frame 2 fixed to one side of the top of the base 1; a steering assembly arranged on one side of the support frame 2; a cylinder 4 installed on the top of the base 1 away from the support frame 2 and used for installing the blades; a clamping assembly arranged outside the cylinder 4 and used for clamping the blades and cooperating with the rotating frame 22 for rotation; When producing automobiles, it is necessary to install air-conditioning blades inside the air-conditioning outlet. When installing the blades, first clamp the automobile air-conditioning outlet inside the steering assembly on one side of the support frame 2, then clamp the blades inside the clamping assembly, adjust the blades to a suitable position through the clamping assembly, then push the clamping assembly through the cylinder 4 so that the blades inside are inserted into the air outlet, then switch the workstations of the steering assembly and the clamping assembly, and assemble again after switching. During the assembly process, add air outlets and blades to idle workstations, so that the time consumed by assembly can be reduced and the efficiency of assembly can be improved.

[0023] Reference Figure 1 As shown, the steering assembly of the present invention includes: a first motor 21, which is installed on one side of the support frame 2; a rotating frame 22, which is rotatably connected to the side of the support frame 2 away from the first motor 21, and the rotating shaft of the first motor 21 is fixedly connected to one side of the rotating frame 22; a fixed clamping plate 23, which is arranged on the side of the rotating frame 22 away from the support frame 2; Before assembly, the air outlet needs to be clamped. At this time, the air outlet is clamped inside the fixed clamp plate 23. After assembly, the first motor 21 is started to drive the rotating frame 22 to turn, which can drive the fixed clamp plate 23 to move out of the assembly station after assembly, and move the next unassembled station into the assembly station.

[0024] Reference Figure 1 - Figure 6 As shown, the clamping assembly of the present invention includes: a rotating ring 3, which is arranged outside the cylinder 4, and the bottom end of the rotating ring 3 is in contact with the top end of the base 1; a clamping seat 35, which is arranged above the rotating ring 3; a flip groove 353, which is opened on both sides of the inside of the clamping seat 35; a guide roller 36, which is arranged inside the clamping seat 35 and is used to clamp the blade; a rolling bracket 361, which is rotatably connected to the outside of the guide roller 36; a conical spring 363, which is fixed to one end of the rolling bracket 361 away from the guide roller 36, and the other end of the conical spring 363 is fixedly connected to the flip groove 353; Before assembly, the blade needs to be clamped inside the clamping seat 35. At this time, the blade is pushed into the clamping seat 35. At this time, the blade will be pushed to both sides by the guide rollers 36 on both sides of the clamping seat 35. At this time, the guide rollers 36 will drive the rolling bracket 361 to move toward the inside of the flip groove 353. During the movement, the rolling bracket 361 will squeeze the conical spring 363. At the same time, the elastic force of the conical spring 363 will push the rolling bracket 361 in the reverse direction. The rolling bracket 361 drives the guide rollers 36 to squeeze the blade, and the blade can be fixed between the guide rollers 36. The guide rollers 36 form a 45° angle with respect to the internal direction of the clamping seat 35, and the blade is fixed close to the inner side of the clamping seat 35 to prevent the blade from slipping from the inside of the clamping seat 35.

[0025] Reference Figure 1-Figure 6As shown, one side of the clamping seat 35 of the present invention further includes: a push plate 34, which is arranged on the side of the clamping seat 35 close to the rotating ring 3; a guide column 33, which is fixed on the side of the push plate 34 away from the clamping seat 35, and the guide column 33 is provided with four groups at the top of the rotating ring 3; a support block 32, which is arranged on one side of the guide column 33, and the bottom end of the support block 32 is fixedly connected to the top of the rotating ring 3; a guide hole 321, which is opened inside the support block 32, and the inner diameter of the support block 32 matches the outer diameter of the guide column 33, and is used to guide the guide column 33; When the blades are assembled into the interior of the air outlet, the cylinder 4 is started to extend the output shaft, and the output shaft pushes the guide column 33 to push the push plate 34 forward. At this time, the guide column 33 moves inside the guide hole 321, and the guide hole 321 can guide the guide column 33. The push plate 34 pushes the clamping seat 35 to move toward the position of the fixed clamping plate 23, and the clamping seat 35 can drive the blade to be inserted into the interior of the air outlet.

[0026] Reference Figure 1-Figure 6 As shown, the side of the guide column 33 of the present invention away from the push plate 34 further includes: a fixing plate 331 fixed to the end of the guide column 33 away from the push plate 34; a first spring 332 sleeved on the outside of the guide column 33, one end of the guide column 33 is fixedly connected to the support block 32, and the other end of the guide column 33 is fixedly connected to the fixing plate 331; a push ball 41 is fixed to the end of the output shaft of the cylinder 4; After the blade is stuck in the air outlet, the cylinder 4 retracts the output shaft. At this time, the elastic force of the first spring 332 pushes the fixed plate 331, and the fixed plate 331 drives the guide column 33 to pull the push plate 34. At this time, the push plate 34 drives the clamping seat 35 to move. During the movement, the clamping seat 35 moves away from the fixed clamping plate 23, and at the same time, the guide roller 36 is flipped 45° to make the moving direction of the guide roller 36 and the clamping seat 35 consistent. During this process, the guide roller 36 drives the flip groove 353 to rotate and tighten through the rolling bracket 361, and then the blade can be separated from the guide roller 36. After separation, the guide roller 36 loses the force of the blade, and the elastic force of the conical spring 363 can push the guide roller 36 to automatically reset to the original position and angle, which is convenient for clamping the blade next time.

[0027] Reference Figure 1-Figure 6 As shown, one side of the clamping seat 35 of the present invention further includes: a guide rod 351, fixed to a side of the clamping seat 35 close to the push plate 34, the guide rod 351 runs through the inside of the push plate 34; a limit block, fixed to a side of the guide rod 351 away from the clamping seat 35; a second spring 352, sleeved on the outside of the guide rod 351, one end of the second spring 352 is fixedly connected to the clamping seat 35, and the other end of the second spring 352 is fixedly connected to the limit block of the guide rod 351; When the cylinder 4 pushes the clamping seat 35 toward the blades of the fixed clamping plate 23, the thrust of the cylinder 4 is relatively large and the material of the blades is mostly plastic, which is easy to be damaged during assembly. Therefore, when the clamping seat 35 pushes the blades for assembly, the second spring 352 will be squeezed. After the second spring 352 is squeezed, the thrust gradually increases. The thrust of the second spring 352 can be used to install the blades inside the air inlet and outlet. At the same time, the elastic force of the second spring 352 can buffer the thrust of the cylinder 4 to prevent the thrust of the cylinder 4 from damaging the blades.

[0028] Reference Figure 1-Figure 6 As shown, the interior of the rotating ring 3 of the present invention further includes: teeth 37, fixed at the bottom end of the rotating ring 3, and multiple teeth 37 are arranged at equal intervals inside the rotating ring 3; gears 311, arranged inside the rotating ring 3, and four gears 311 are arranged at equal intervals inside the rotating ring 3, and the gears 311 are meshed and connected with the rotating ring 3 through the teeth 37; a second motor 31, installed at the bottom end of the base 1, and the end of the rotating shaft of the second motor 31 is fixedly connected to one of the gears 311; After installing the blades, it is necessary to switch the workstation above the rotating ring 3. At this time, the second motor 31 is started to drive the gear 311 to rotate. The gear 311 drives the rotating ring 3 to rotate through the teeth 37. The rotating ring 3 can drive the workstation above to switch. The other three gears 311 can support the rotating ring 3. The workstation switching of the rotating ring 3 is synchronized with the workstation switching of the rotating frame 22, which can reduce the time consumed in switching workstations.

[0029] Reference Figure 1-Figure 8 As shown, the present invention further includes between the rotating ring 3 and the supporting frame 2: a fixing frame 5, which is arranged between the rotating ring 3 and the supporting frame 2, and two fixing frames 5 are arranged about the vertical center line of the rotating ring 3, and the bottom end of the fixing frame 5 is fixedly connected to the top end of the base 1; a positioning frame 51, which is arranged between the two fixing frames 5, and two positioning frames 51 are arranged about the horizontal center line of the fixing frame 5; a top block, which is arranged at one end of the two positioning frames 51 close to the clamping seat 35, and is used to push the blade to reset; a sliding rod 52, which is fixed inside the fixing frame 5, and both ends of the positioning frame 51 are slidably connected to the outside of the sliding rod 52; a third spring 53, which is fixed to the top and bottom ends inside the fixing frame 5, and the other end of the third spring 53 is fixedly connected to the positioning frame 51, and the third spring 53 is sleeved on the outside of the sliding rod 52; When one set of the clamping seats 35 rotates to the assembly station, the blades inside the clamping seats 35 may not be aligned with the air outlet position inside the fixed clamping plate 23. At this time, the positioning frame 51 is pulled to squeeze the third spring 53, and then the positioning frame 51 is released after the clamping seat 35 rotates. At this time, the elastic force of the third spring 53 pushes the positioning frame 51 to drive the top block to push the blades. The two positioning frames 51 push the blades at the same time to make the blades in the middle position of the fixing frame 5.

[0030] Reference Figure 1-Figure 8As shown, the interior of the conical spring 363 of the present invention further includes: a telescopic rod 362, which is arranged inside the conical spring 363, and one end of the telescopic rod 362 is fixedly connected to the rolling bracket 361; a movable hole 354, which is opened at the end of the flip groove 353 away from the guide roller 36, and the end of the telescopic rod 362 away from the rolling bracket 361 is inserted into the interior of the movable hole 354; When the positioning frame 51 presses the blade, it will drive the blade to move. During the movement, the up and down movement of the blade will drive the guide roller 36 to rotate, so that the guide roller 36 and the base 1 are perpendicular. At this time, the guide roller 36 can assist the blade to adjust. After the adjustment is completed, the guide roller 36 will automatically reset to the original angle under the action of the conical spring 363, which can facilitate the subsequent assembly of the blade.

[0031] Reference Figure 1-Figure 8 As shown, one side of the fixing frame 5 of the present invention further includes: a winding roller 54, which is arranged on one side of the fixing frame 5; a support plate 543, which is rotatably connected to both ends of the winding roller 54, and one side of the support plate 543 is fixedly connected to the fixing frame 5; a third motor 542, which is installed at one end of the support plate 543, and the end of the rotating shaft of the third motor 542 is fixedly connected to one end of the winding roller 54; a pull rope 541, which is fixed to the outside of the winding roller 54, and the other end of the pull rope 541 is fixedly connected to one end of the positioning frame 51 away from the third spring 53, and through holes for moving the pull rope 541 are opened above and below the fixing frame 5 near the winding roller 54 side; Before the rotating ring 3 rotates to switch the workstation, the positioning frame 51 needs to be opened. At this time, the third motor 542 is started to rotate and drive the winding roller 54 to reel in the pull rope 541. During the reeling process, the pull rope 541 pulls the positioning frames 51 to separate. After separation, the workstation to be assembled at the top of the rotating ring 3 can be moved into the position between the positioning frames 51. Then, the third motor 542 is powered off to release the positioning frame 51. At this time, the elastic force of the third spring 53 pushes the positioning frame 51 to move, and the positioning frame 51 pulls the pull rope 541 to reset the position of the pull rope 541 for subsequent use.

[0032] Obviously, the above embodiments are merely examples for clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from these are still within the protection scope of the invention.
