Description

Technical Field

[0001] The invention relates to the technical field of foam laminating devices, and in particular to a foam laminating device for automobile parts. Background Art

[0002] With the development of the automobile industry, foam for sound insulation is often configured inside the tires of its components. Its design purpose is to weaken the resonance noise generated when the tires are running, especially to significantly reduce the road noise.

[0003] At present, when bonding the foam in the automobile tire, the user is often required to use a glue gun to spray glue on the inner wall of the tire, and then insert the foam into the tire for bonding. After the foam is bonded, the foam needs to be squeezed with a pressure roller to improve the bonding effect of the foam. The work efficiency is low, and after the foam is bonded, the defects on the surface cannot be detected. For example, if there is a broken layer on the surface of the foam, it will affect the subsequent quiet effect of the foam.

[0037] An actuator for laminating the foam is provided inside the box 1;

[0038] The actuator includes a plurality of vertical plates 35 evenly distributed and fixedly connected to the inner wall of the annular cavity 5, and the side wall of each vertical plate 35 is rotatably connected to a transmission gear 36 (such as Figure 8 As shown in the figure, a toothed belt 37 is fixedly installed on the side wall of the first rack 7, and a plurality of second racks 38 are evenly slidably connected to the inner wall of the round block 4. The transmission gear 36 is meshed with the toothed belt 37, and the transmission gear 36 is meshed with the second rack 38. One end of the second rack 38 is fixedly connected to a round rod 39, and one end of the round rod 39 is fixedly connected to an electric clamp 41. The electric clamp 41 is a prior art, and different clamping forces can be controlled on the foam through two telescopic clamps. Each side wall of the round rod 39 is fixedly connected to a guide rod 42 (as shown in the figure). Figure 7 As shown), the side wall of the round block 4 is evenly rotatably connected with multiple round tubes 40, and the inner wall of each round tube 40 is provided with a combined groove 43, the combined groove 43 includes a spiral groove and two sections of vertical grooves, the spiral groove is arranged in the middle, and the two sections of vertical grooves are arranged at both ends of the spiral groove, and the guide rod 42 is slidably connected inside the combined groove 43.

[0039] The actuator also includes a second gear 44 fixedly connected to the side wall of the circular tube 40, and a plurality of third gears 45 are rotatably connected to the side wall of the circular block 4. The spline shaft 8 slides through the corresponding third gears 45, and the second gear 44 and the third gear 45 are meshed and connected.

[0040] A plurality of heating resistors 49 are embedded in the inner wall of the extrusion roller 11. The heating resistors 49 are prior art, have their own power supply and generate heat when turned on. The extrusion roller 11 preheats the tire when sliding against the inner wall of the tire, thereby improving the subsequent glue coating quality. The synchronous gear 22 is meshedly connected to the annular rack 21, and the synchronous gear 22 is meshedly connected to the adjacent first rack 7.

[0041] The bracket 9 is in a U-shaped structure, and a hydraulic push rod 46 is embedded and fixedly connected to the top wall of the box body 1. The hydraulic push rod 46 is a prior art and will not be described in detail here. The movable end of the hydraulic push rod 46 is fixedly installed on the top of the cross plate 2, and a placement table 47 is installed on the bottom inner wall of the box body 1.

[0042] In the present invention, the user selects a tire of a certain specification and places it upside down on the placement table 47, and it is clamped and fixed by an external clamping device. Then the user stuffs the foam for silencing into multiple electric clamps 41, and the multiple electric clamps 41 clamp it, and turn on the hydraulic push rod 46. The movable end of the hydraulic push rod 46 drives the cross plate 2 to slide downward in the vertical direction for a distance, so that the motor 3 drives the round block 4 to enter the interior of the tire.

[0043] Then the micro motor 23 is turned on by the controller. The micro motor 23 is a forward and reverse motor. Figure 2As shown, first, the output end of the micro motor 23 drives the synchronous gear 22 fixedly connected to it to rotate clockwise by a certain angle, then the synchronous gear 22 will drive the annular rack 21 meshing with it to slide on the inner wall of the annular cavity 5 to produce a clockwise rotation effect, then the annular rack 21 will drive the other multiple synchronous gears 22 to rotate synchronously, so that each first rack 7 slides a distance away from the center of the circle 4, then the first rack 7 will drive the spline shaft 8 to move synchronously through the reset spring 25, so that the bracket 9 fixedly connected to one end of the spline shaft 8 drives the squeezing roller 11 and the glue spray heads 13 on the multiple L-shaped rods 12 to move synchronously until the squeezing roller 11 and the inner wall of the tire are in contact, and the heating resistor 49 embedded in the squeezing roller 11 can preheat the inner wall of the tire after being started, so as to improve the subsequent glue coating quality. At this time, the motor 3 is turned on, and the output end of the motor 3 drives the circle 4 to rotate, then the circle 4 will The first rack 7 and other structures will drive multiple brackets 9 and squeezing rollers 11 to rotate. Since the surface of the squeezing roller 11 has a certain friction force, the squeezing roller 11 will rotate in this process, and the squeezing roller 11 will drive the roller shaft 10 to rotate. Since the two ends of the roller shaft 10 are respectively fixedly connected with cross bars 14, each cross bar 14 drives the connecting rod 15 to move through the circular shaft 16 when rotating with the roller shaft 10, so that the connecting rod 15 drives the sliding plug 18 rotatably connected thereto to slide back and forth in the corresponding glue box 17 in a sealed manner. Since the axial directions of the two cross bars 14 are arranged in opposite directions, there will always be a sliding plug 18 that draws the glue in the glue storage box 34 into the glue box 17 through the one-way liquid inlet pipe 19 during the sealed sliding, and there will always be a sliding plug 18 that squeezes the glue drawn into the glue box 17 to the multiple glue spray nozzles 13 through the one-way liquid outlet pipe 20 during the sealed sliding, and sprays it onto the inner wall of the tire.

[0044] Then as Figure 2As shown, the output end of the micro motor 23 drives the synchronous gear 22 fixedly connected thereto to rotate counterclockwise, and the synchronous gear 22 will drive the annular rack 21 meshing therewith to slide on the inner wall of the annular cavity 5 to produce a counterclockwise rotation effect, and the annular rack 21 will drive the other multiple synchronous gears 22 to rotate synchronously, so that each first rack 7 slides a distance toward the center of the circular block 4, and since each side wall of the first rack 7 is fixedly connected with a toothed belt 37, the first rack 7 will drive the transmission gear 36 meshing therewith to rotate through the toothed belt 37, and the transmission gear 36 drives the second rack 38 meshing therewith to slide a distance away from the center of the circular block 4, and the second rack 38 drives the round rod 39 and the electric clamp 41 to move synchronously, thereby pushing the foam outward. When the round rod 39 slides, the round rod 39 The guide rod 42 fixedly connected to the side wall will slide inside the combined groove 43. First, the guide rod 42 will slide in the spiral groove portion of the combined groove 43, so that the round tube 40 rotates a certain angle, and then the round tube 40 will drive the second gear 44 fixedly connected thereto to rotate. By setting the transmission ratio of the second gear 44 and the third gear 45, the second gear 44 drives the third gear 45 meshing therewith to rotate ninety degrees, and the third gear 45 drives the bracket 9 to rotate ninety degrees through the spline shaft 8. Then the bracket 9 will drive the squeezing roller 11 to rotate ninety degrees through the roller shaft 10, and then the guide rod 42 will enter the vertical groove portion of the combined groove 43 to slide, and finally the bracket 9 and the squeezing roller 11 will be misaligned with the movement of the electric clamp 41 without interference, and then the electric clamp 41 will drive the foam clamped therewith and the glue just applied to the inner wall of the tire to be bonded together.

[0045] like Figure 2As shown, finally, the output end of the micro motor 23 drives the synchronous gear 22 fixedly connected thereto to rotate clockwise by a certain angle, so that the first rack 7 drives the squeezing roller 11 to contact the side wall of the bonded foam through the spline shaft 8, the bracket 9 and the roller shaft 10, and the electronic valve in the one-way liquid inlet pipe 19 is closed and the motor 3 is turned on, so that the round block 4 drives the squeezing roller 11 to rotate through multiple first racks 7 and other structures to squeeze the bonded foam to improve the bonding effect. At this time, since the electronic valve in the one-way liquid inlet pipe 19 is closed, the squeezing roller 11 will not rotate, and the squeezing roller 11 always squeezes the foam at a fixed position, thereby improving the accuracy of the detection. When there are defects in the surface quality of the foam, such as the foam When the foam surface is broken, when the squeezing roller 11 contacts the broken part of the foam surface, under the action of the reset spring 25, the squeezing roller 11 will penetrate into the broken part of the foam surface, and the spline shaft 8 will drive the first gear 27 to move synchronously for a distance through the support plate 26. Since the first gear 27 is respectively meshed with the static rack 28 and the movable rack 29, the first gear 27 will drive the sliding stroke of the movable rack 29 to double, so that the movable rack 29 drives the conductive block 31 on the connecting plate 30 to slide on the conductive strip 32 to double the distance, thereby magnifying the defects on the foam surface. When the conductive block 31 and the conductive strip 32 are out of contact, the work light 33 will be turned off to remind the user that there are large surface quality defects on the foam.

[0046] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
