Description

Technical Field

[0001] The present invention relates to the technical field of automotive interior processing, and more specifically, to a constant-temperature hot-pressing and wrapping tooling for automotive interior parts. Background Art

[0002] With the rapid development of automotive technology, a large number of new technologies, new materials, and new processes have been widely applied in automobiles, greatly improving the power performance, economy, safety, emissions, and comfort of automobiles. To meet the requirements of users for automotive interiors, the current automotive manufacturing industry has adopted the method of wrapping veneer materials such as leather or fabric on the interior panel to increase comfort.

[0003] The existing wrapping method usually involves spraying glue on the surface of the interior panel before wrapping to make it composite with the veneer material, and then wrapping it through a wrapping machine. Therefore, when wrapping, it is necessary to spray glue on the surface of the interior panel first to make it composite with the veneer material, and then wrap it through a wrapping machine, resulting in low wrapping accuracy. Then, the prior art has improved this problem. For example, a constant-temperature hot-pressing and wrapping tooling for automotive interior parts in CN113733541A can achieve automatic hot-pressing and wrapping by fixing the interior panel and the veneer material on the upper die and the lower die respectively, and wrap the veneer material well on the interior panel. Compared with the prior art, the wrapping accuracy is higher. However, in actual use, it is necessary to fix the interior panel and the veneer material on the upper die and the lower die respectively for hot-pressing and wrapping. But when the interior panel needs to be installed upside down and docked with the upper die for positioning, it is not only inconvenient to operate, but also not easy to observe the docking situation with the upper die, resulting in the interior panel often not being able to be placed in place at one time, seriously affecting the wrapping effect.

[0004] In response to the above problems, some solutions have also been given in the prior art. For example, the Chinese invention patent with the publication number

[0005] CN118238427B discloses a hot-pressing and forming wrapping device for automotive interior parts. When the control rod is clamped to the second slot, the rotating disk and the sleeve disk are relatively fixed. By controlling the driving worm to drive the worm gear section to rotate half a circle, the rotating disks and the sleeve disks on both sides rotate synchronously by half a circle based on the connecting plate. Thus, after the interior panel is placed and positioned on the lower convex module, the upper concave module can be driven to turn to the lower side, facilitating the placement and positioning of the veneer material. The prior art directly adsorbs the interior panel on the surface of the convex template and fixes the interior panel through suction. However, in the actual use process, since the position of the interior panel is manually placed and there may be a certain error in the manually placed position, the interior panel cannot be accurately positioned directly below the concave module, so that the veneer material cannot be aligned with the interior panel during the die pressing process, and the veneer material cannot be accurately wrapped on the interior panel, seriously affecting the wrapping effect of the interior panel. Summary of the Invention

[0006] In view of the problems existing in the prior art, the purpose of the present invention is to provide a constant temperature hot pressing cladding tool for automobile interior decoration parts, which can achieve the purpose of improving the cladding effect of interior decoration panels.

[0012] Furthermore, the control component includes a connecting hole provided on the linkage block, and the connecting hole is connected to the first air pipe, and a second air pipe connected to the cavity is inserted into the connecting hole.

[0013] Further, a solenoid valve with an input end communicating with the outside is inserted into the cavity, and the solenoid valve is electrically connected to the heating wire. An exhaust valve is inserted into the cavity. A diversion groove is formed in the mounting plate, and diversion holes are formed in the side wall of the diversion groove.

[0014] Further, a groove is formed in the horizontal plate, and a sealing rod is slidably mounted in the groove. A third spring is jointly mounted between the sealing rod and the horizontal plate. A communication groove is formed in the sealing rod, and the communication groove communicates with the output end of the exhaust valve. A diversion pipe communicating with the diversion groove is inserted into the groove.

[0015] Further, a heat preservation box cooperating with the mounting plate is mounted on the bottom wall of the top plate.

[0016] Further, a roller is rotatably mounted at one end of the push rod away from the linkage block.

[0017] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0018] (1) In this solution, through the cooperation of the magnet block and the coil, the coil is energized to generate an electromagnetic field. Under the action of the electromagnetic field, the magnet block drives the mounting rod to move along the sliding groove and stretch the first spring. During the movement of the mounting rod, the first alignment block can be driven to move. During the movement of the first alignment block, it gradually contacts the inner wall of the interior trim panel and drives the interior trim panel to move. Then, during the movement of the interior trim panel, the side wall of the interior trim panel away from the first alignment block gradually contacts the second alignment block. At this time, the first alignment block and the second alignment block can align the interior trim panel in the left-right direction and clamp the interior trim panel, so that the interior trim panel is located directly below the mounting plate and the interior trim panel is aligned with the facing material, playing a role in improving the wrapping effect;

[0019] (2) In this solution, by setting the linkage block, when the first clamping block drives the interior trim panel to contact the second clamping block, the first clamping block and the second clamping block respectively drive the corresponding push rods to contact the inner side wall of the interior trim panel. And as the first clamping block moves, the interior trim panel will exert a thrust on the two push rods. Then, under the action of the thrust, the push rods move along the mounting groove. During the movement of the push rods, they gradually contact the inclined surface of the linkage block and exert a thrust on the inclined surface of the linkage block. Then, under the action of the thrust, the linkage block moves out of the linkage groove. At this time, the second spring is compressed and has a tendency to recover. During the movement of the linkage block out of the linkage groove, it gradually contacts the inner side walls of the front and rear sides of the interior trim panel and exerts a thrust on the inner side walls of the front and rear sides. Then, under the action of the thrust, the front and rear positions of the interior trim panel can be aligned, further ensuring that the interior trim panel is aligned with the facing material and further improving the wrapping effect;

[0020] (3) In this solution, by providing a cavity and air holes, when the electric telescopic rod contracts and drives the bottom plate to move closer to the top plate, the elastic pad is stretched and has a tendency to recover. During the stretching process of the elastic pad, the gas pressure in the air cavity decreases, and there is a tendency to suck air from the outside. Then, after the linkage block aligns the interior trim panel, the second spring reaches its maximum compression degree. At this time, the linkage block drives the communication hole to communicate with the second air pipe. At this time, the air cavity sucks air from the cavity through the first air pipe, the communication hole, and the second air pipe, and causes the cavity to recover. Then, the cavity has a tendency to suck air from the outside through the air holes. Since the side wall of the linkage block is in contact with the inner wall of the inner side wall at this time, the inner wall of the interior trim panel blocks the air holes. Therefore, under the action of the gas pressure in the cavity, the linkage block and the inner wall of the interior trim panel are tightly sucked together, thus preventing the interior trim panel from moving during the wrapping process and affecting the wrapping effect, and further improving the wrapping effect.

[0021] (4) In this solution, by providing a diversion groove, when the electric telescopic rod extends and drives the bottom plate to reset, the elastic pad contracts. At this time, the gas pressure in the air cavity increases. During the process of the bottom plate moving downward, it gradually contacts the sealing rod and exerts a downward thrust on the sealing rod. Then, under the action of the thrust, the sealing rod moves downward and stretches the third spring. After the bottom plate finishes resetting, the sealing rod drives the communication groove to communicate with the diversion pipe. At this time, the air flow in the air cavity flows through the exhaust valve, the communication groove, and the diversion pipe to the diversion groove, and blows through the diversion holes on the diversion groove to the interior trim panel after wrapping, thus accelerating the air flow rate at the wrapping part of the interior trim panel, and further accelerating the cooling speed of the glue at the wrapping part, and further improving the wrapping efficiency.

[0037] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention; obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0038] Please refer to Figures 1 to 8 , an automotive interior part constant temperature hot pressing and wrapping tooling, including a workbench 1, a mounting frame 2 is fixedly installed on the top wall of the workbench 1, a mounting disc 3 is rotatably installed on the mounting frame 2, a motor 4 with an output end fixedly connected to the mounting disc 3 is fixedly installed on the mounting frame 2, a bottom plate 5 is fixedly installed on the mounting disc 3, an alignment component 10 is arranged on the bottom plate 5, a top plate 6 is fixedly installed on the mounting disc 3, and an electric telescopic rod 7 is commonly installed between the bottom plate 5 and the top plate 6. A mounting plate 8 is fixedly installed on the top plate 6, and a heating wire 9 is arranged on the mounting plate 8;

[0039] The alignment component 10 includes a first mounting block 101 fixedly installed on the bottom plate 5. A chute is formed in the first mounting block 101. A mounting rod 102 is slidably installed in the chute. A first spring 103 is jointly installed between the mounting rod 102 and the chute. One end of the mounting rod 102 away from the first spring 103 is fixedly installed with a first alignment block 104. A second alignment block 105 cooperating with the first alignment block 104 is provided on the top wall of the bottom plate 5. A coil 106 electrically connected to the motor 4 is provided on the first mounting block 101. A magnet block 107 cooperating with the coil 106 is provided on the mounting rod 102. A linkage component 11 is provided on the first alignment block 104 and the second alignment block 105.

[0040] The linkage component 11 includes linkage grooves formed in the first alignment block 104 and the second alignment block 105. Linkage blocks 111 are symmetrically and slidably installed in the linkage grooves. A second spring 112 is jointly installed between the linkage blocks 111 and the linkage grooves. The side walls of adjacent sides of the two linkage blocks 111 are inclined surfaces. Mounting grooves are formed in the side walls of the linkage grooves. Push rods 113 are slidably installed in the mounting grooves.

[0041] In the initial state, the first spring 103 is in a free extension state. During use, first place the interior trim panel on the top wall of the bottom plate 5, and make the alignment component 10 located inside the interior trim panel. Then, the user can start the motor 4 first. At this time, the coil 106 is energized and generates an electromagnetic field. Under the action of the electromagnetic field, the magnet block 107 drives the mounting rod 102 to move along the chute and stretches the first spring 103. During the movement of the mounting rod 102, it can drive the first alignment block 104 to move. During the movement of the first alignment block 104, it gradually contacts the inner wall of the interior trim panel and drives the interior trim panel to move. Then, during the movement of the interior trim panel, the side wall of the interior trim panel far from the first alignment block 104 gradually contacts the second alignment block 105. At this time, the first alignment block 104 and the second alignment block 105 can align the interior trim panel in the left-right direction and clamp the interior trim panel. Then, the user can control the motor 4 to rotate 180 degrees. During the rotation of the motor 4, it drives the mounting plate 3 to rotate 180 degrees. At this time, the upper and lower positions of the bottom plate 5 and the top wall are swapped. Then, the user can place the veneering material on the mounting plate 8 and energize the heating wire 9. At this time, the heating wire 9 can heat the glue on the veneering material and melt the glue on the veneering material. Then, the user can control the electric telescopic rod 7 to contract. During the contraction of the electric telescopic rod 7, it drives the bottom plate 5 to move downward. During the downward movement of the bottom plate 5, it drives the interior trim panel to move downward and gradually fit with the bonding material, thus achieving the purpose of covering the veneering material on the interior trim panel. And by setting the first alignment block 104 and the second alignment block 105, the position of the interior trim panel in the left-right direction can be adjusted, so that the interior trim panel is located directly below the mounting plate 8 and the interior trim panel is aligned with the veneering material, playing a role in improving the covering effect.

[0042] When the first clamping block drives the interior trim panel to contact the second clamping block, the first clamping block and the second clamping block respectively drive the corresponding push rods 113 to contact the inner side wall of the interior trim panel. And as the first clamping block moves, the interior trim panel will exert a thrust on the two push rods 113. Then, under the action of the thrust, the push rods 113 move along the mounting groove. During the movement of the push rods 113, they gradually contact the inclined surface of the linkage block 111 and exert a thrust on the inclined surface of the linkage block 111. Then, under the action of the thrust, the linkage block 111 moves out of the linkage groove. At this time, the second spring 112 is compressed and has a tendency to recover. During the movement of the linkage block 111 out of the linkage groove, it gradually contacts the inner side walls on the front and rear sides of the interior trim panel and exerts a thrust on the inner side walls on the front and rear sides. Then, under the action of the thrust, the position of the interior trim panel in the front-rear direction can be aligned, further ensuring that the interior trim panel is aligned with the veneering material and further improving the covering effect.

[0043] Such as Figure 3 、 Figure 7As shown, a cavity 121 is formed on the linkage block 111, and an air hole 122 is formed on the cavity 121. A horizontal plate 123 is fixedly installed on the mounting plate 3. An elastic pad 124 is jointly installed between the horizontal plate 123 and the bottom plate 5. An air cavity 125 is formed on the elastic pad 124. A first air pipe 126 is inserted into the air cavity 125. A control component 127 is provided on the linkage block 111, and one end of the first air pipe 126 away from the air cavity 125 is communicated with the cavity 121 through the control component 127.

[0044] The control component 127 includes a communication hole 1271 formed on the linkage block 111, and the communication hole 1271 is communicated with the first air pipe 126. A second air pipe 1272 communicated with the cavity 121 is inserted into the communication hole 1271.

[0045] By adopting the above technical solution, during the process that the electric telescopic rod 7 contracts and drives the bottom plate 5 to approach the top plate 6, the elastic pad 124 is stretched and has a tendency to recover. And during the process that the elastic pad 124 is stretched, the gas pressure in the air cavity 125 decreases and has a tendency to suck air from the outside. Then after the linkage block 111 aligns the interior trim panel, the second spring 112 reaches the maximum compression degree. And at this time, the linkage block 111 drives the communication hole 1271 to be communicated with the second air pipe 1272. At this time, the air cavity 125 sucks air from the cavity 121 through the first air pipe 126, the communication hole 1271, and the second air pipe 1272, and enables the cavity 121 to recover. Then the cavity 121 has a tendency to suck air from the outside through the air hole 122. Since the side wall of the linkage block 111 is attached to the inner wall of the inner side wall at this time, the inner wall of the interior trim panel blocks the air hole 122 at this time. Therefore, under the action of the gas pressure in the cavity 121, the linkage block 111 is tightly sucked together with the inner wall of the interior trim panel, thereby avoiding the movement of the interior trim panel during the wrapping process and affecting the wrapping effect, and further improving the wrapping effect.

[0046] As Figure 6 、 Figure 7 As shown, a solenoid valve 131 with an input end communicated with the outside is inserted into the cavity 121, and the solenoid valve 131 is electrically connected to the heating wire. An exhaust valve 132 is inserted into the cavity 121. A diversion groove 133 is formed on the mounting plate 3. Diversion holes 134 are formed on the side wall of the diversion groove 133.

[0047] A groove is formed on the horizontal plate 123. A sealing rod 135 is slidably installed in the groove. A third spring 136 is jointly installed between the sealing rod 135 and the horizontal plate 123. A communication groove 137 is formed on the sealing rod 135, and the communication groove 137 is communicated with the output end of the exhaust valve 132. A diversion pipe 138 communicated with the diversion groove 133 is inserted into the groove.

[0048] By adopting the above technical solution, when the heating wire 9 is energized and heats the veneering material, the solenoid valve 131 is energized and in a closed state. Then, after the veneering is completed, the user can first control the installation plate 3 to reverse through the motor 4, and then drive the top plate 6 and the bottom plate 5 to reverse during the reverse process of the installation plate 3, so that the bottom plate 5 is located below again. After the reverse is completed, the user can turn off the heating wire 9. At this time, the solenoid valve 131 is de-energized and in an open state. Since the elastic pad 124 is in a stretched state, the air chamber 125 sucks air from the outside through the solenoid valve 131. At this time, the negative pressure effect between the linkage block 111 and the interior trim panel is released. Then, the electric telescopic rod 7 and the motor 4 are de-energized. At this time, the elastic pad 124 contracts and drives the bottom plate 5 to reset downward. During the downward reset process of the bottom plate 5, the interior trim panel and the top plate 6 are gradually separated. At the same time, the coil 106 is de-energized and the electromagnetic field disappears. Then, the first spring 103 contracts and drives the mounting rod 102 to reset. During the reset process of the mounting rod 102, the first alignment block 104 is driven to reset. During the reset process of the first alignment block 104, the push rod 113 is gradually separated from the interior trim panel. At this time, the second spring 112 contracts and drives the linkage block 111 to move into the linkage groove. During the movement of the linkage block 111, the push rod 113 is driven to reset through the inclined surface. Then, after the first alignment block 104 is reset, the fixing effect of the interior trim panel is released, which facilitates the user to remove the interior trim panel and improves the wrapping efficiency.

[0049] Then, during the process that the electric telescopic rod 7 extends and drives the bottom plate 5 to reset, the elastic pad 124 contracts. At this time, the gas pressure in the air chamber 125 increases. During the downward movement of the bottom plate 5, it gradually contacts the sealing rod 135 and applies a downward thrust to the sealing rod 135. Then, under the action of the thrust, the sealing rod 135 moves downward and stretches the third spring 136. And after the bottom plate 5 is reset, the sealing rod 135 drives the communication groove 137 to communicate with the diversion pipe 138. At this time, the air flow in the air chamber 125 flows through the exhaust valve 132, the communication groove 137, the diversion pipe 138 to the diversion groove 133, and blows to the wrapped interior trim panel through the diversion holes 134 on the diversion groove 133, thereby accelerating the air flow rate at the wrapped part of the interior trim panel, further accelerating the cooling speed of the glue at the wrapped part, and further improving the wrapping efficiency.

[0050] As Figure 8 shown, a heat preservation box 14 cooperating with the mounting plate 8 is installed on the bottom wall of the top plate 6.

[0051] By adopting the above technical solution, by setting the heat preservation box 14, the wrapped part of the interior trim panel can be heat-preserved and a constant temperature environment can be provided for the wrapped part of the interior trim panel, so as to avoid large temperature differences during the wrapping of the interior trim panel and affect the wrapping effect, which plays a role in improving the wrapping effect.

[0052] As Figure 2As shown, a roller 16 is rotatably installed at one end of the push rod 113 away from the linkage block 111.

[0053] By adopting the above technical solution, during the process of the linkage block 111 aligning the interior trim panel, since the push rod 113 is in contact with the inner wall of the interior trim panel, sliding friction will occur between the push rod 113 and the interior trim panel during the movement of the interior trim panel. By providing the roller 16, the push rod 113 will drive the roller 16 to contact the interior trim panel instead of the push rod 113, and then the roller 16 will be driven to roll when the interior trim panel moves. Furthermore, the sliding friction between the interior trim panel and the push rod 113 can be converted into the rolling friction between the interior trim panel and the roller 16, thereby reducing the wear of the interior trim panel and also reducing the resistance when the interior trim panel moves back and forth, ensuring that the linkage block 111 can normally drive the interior trim panel to move.

[0054] Working principle: In the initial state, the first spring 103 is in a free extension state. When in use, first place the interior trim panel on the top wall of the bottom plate 5, and make the alignment assembly 10 located inside the interior trim panel. Then, the user can start the motor 4 first. At this time, the coil 106 is energized and generates an electromagnetic field. Under the action of the electromagnetic field, the magnet block 107 drives the mounting rod 102 to move along the chute and stretches the first spring 103. During the movement of the mounting rod 102, it can drive the first alignment block 104 to move. During the movement of the first alignment block 104, it gradually contacts the inner wall of the interior trim panel and drives the interior trim panel to move. Then, during the movement of the interior trim panel, the side wall of the interior trim panel away from the first alignment block 104 gradually contacts the second alignment block 105. At this time, the first alignment block 104 and the second alignment block 105 can align the interior trim panel in the left-right direction and clamp the interior trim panel. Then, the user can control the motor 4 to rotate 180 degrees. During the rotation of the motor 4, it drives the mounting plate 3 to rotate 180 degrees. At this time, the up-and-down positions of the bottom plate 5 and the top wall are swapped. Then, the user can place the facing material on the mounting plate 8 and energize the heating wire 9. At this time, the heating wire 9 can heat the glue on the facing material and melt the glue on the facing material. Then, the user can control the electric telescopic rod 7 to contract. During the contraction of the electric telescopic rod 7, it drives the bottom plate 5 to move downward. During the downward movement of the bottom plate 5, it drives the interior trim panel to move downward and gradually fit with the bonding material, thus achieving the purpose of covering the facing material on the interior trim panel, and by setting the first alignment block 104 and the second alignment block 105, the position of the interior trim panel in the left-right direction can be adjusted, so that the interior trim panel is located directly below the mounting plate 8; when the first clamping block drives the interior trim panel to contact the second clamping block, the first clamping block and the second clamping block respectively drive the corresponding push rods 113 to contact the inner side wall of the interior trim panel. And as the first clamping block moves, the interior trim panel will exert a thrust on the two push rods 113. Then, under the action of the thrust, the push rods 113 move along the mounting groove. During the movement of the push rods 113, they gradually contact the inclined surface of the linkage block 111 and exert a thrust on the inclined surface of the linkage block 111. Then, under the action of the thrust, the linkage block 111 moves out of the linkage groove. At this time, the second spring 112 is compressed and has a tendency to recover. During the movement of the linkage block 111 out of the linkage groove, it gradually contacts the inner side walls on the front and rear sides of the interior trim panel and exerts a thrust on the inner side walls on the front and rear sides. Then, under the action of the thrust, the position of the interior trim panel in the front-rear direction can be aligned;When the electric telescopic rod 7 contracts and drives the bottom plate 5 to approach the top plate 6, the elastic pad 124 is stretched and has a tendency to recover. In the process of the elastic pad 124 being stretched, the gas pressure in the air cavity 125 decreases and there is a tendency to inhale air from the outside. Then, after the linkage block 111 straightens the interior panel, the second spring 112 reaches the maximum compression degree, and at this time, the linkage block 111 drives the connecting hole 1271 to communicate with the second air pipe 1272. At this time, the air cavity 125 inhales air from the cavity 121 through the first air pipe 126, the connecting hole 1271, and the second air pipe 1272, and the cavity 121 is restored. Then, the cavity 121 has a tendency to inhale air from the outside through the air hole 122. Since the side wall of the linkage block 111 is in contact with the inner wall of the inner side wall at this time, the inner wall of the interior panel blocks the air hole 122. The moving block 111 is tightly sucked together with the inner wall of the interior panel, thereby preventing the interior panel from moving during the covering process; when the electric telescopic rod 7 extends and drives the bottom plate 5 to reset, the elastic pad 124 contracts, and the gas pressure in the air cavity 125 increases. When the bottom plate 5 moves downward, it gradually contacts the sealing rod 135 and applies a downward thrust to the sealing rod 135. Then, under the action of the thrust, the sealing rod 135 moves downward and stretches the third spring 136. After the bottom plate 5 is reset, the sealing rod 135 drives the connecting groove 137 to communicate with the guide pipe 138. At this time, the airflow in the air cavity 125 flows to the guide groove 133 through the exhaust valve 132, the connecting groove 137, and the guide pipe 138, and blows to the interior panel that has been covered through the guide hole 134 on the guide groove 133, thereby accelerating the air flow rate at the covering of the interior panel, and further accelerating the cooling rate of the glue at the covering. ;

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
