Description

Technical Field

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

[0002] With the rapid development of automobile technology, a large number of new technologies, new materials and new processes have been widely used in automobiles, which have greatly improved the power, economy, safety, emissions and comfort of automobiles. In order to meet users' requirements for automobile interiors, the automobile manufacturing industry has currently adopted the method of covering the interior panels with leather or fabric veneer materials to increase comfort.

[0003] The existing coating method is usually to spray glue on the surface of the interior panel before coating so that it can be compounded with the veneer material, and then coat it through a coating machine. Therefore, when coating, it is necessary to spray glue on the surface of the interior panel first so that it can be compounded with the veneer material, and then coat it through a coating machine, resulting in low coating accuracy. Then the existing technology has made improvements to this problem. For example, CN113733541A is a constant temperature hot pressing coating tool for automobile interior parts. By fixing the interior panel and the veneer material on the upper mold and the lower mold respectively, automatic hot pressing coating can be achieved, and the veneer material can be well coated on the interior panel. Compared with the existing technology, the coating accuracy is higher, but in actual use, the interior panel and the veneer material need to be fixed on the upper mold and the lower mold respectively for hot pressing coating. However, when the interior panel is installed, it needs to be inverted and docked with the upper mold. It is not only inconvenient to operate, but also inconvenient to observe the docking situation with the upper mold, resulting in that the interior panel often cannot be placed in place at one time, which seriously affects the coating effect.

[0004] In view of the above problems, some solutions are also provided in the prior art, such as the announcement number The Chinese invention patent CN118238427B discloses a hot pressing and covering device for automobile interior decoration parts. When the control lever is connected to the second card slot, the rotating disk and the sleeve disk are relatively fixed, and the control driving worm drives the worm gear segment to rotate half a circle. The rotating disks and the sleeve disks on both sides rotate half a circle synchronously based on the connecting plate, so that after the interior decoration panel is placed and positioned on the convex module on the lower side, the concave module on the upper side can be driven to rotate to the lower side, which is convenient for the placement and positioning of the veneer material. The prior art is to directly adsorb the interior decoration panel on the surface of the convex template and fix the interior decoration panel by suction. However, in actual use, since the position of the interior decoration panel is manually placed and there may be certain errors in the manually placed position, the interior decoration panel cannot be accurately positioned directly below the concave module, so that the veneer material cannot be aligned with the interior decoration panel during the die pressing process, and the veneer material cannot be accurately wrapped on the interior decoration panel, which seriously affects the covering effect of the interior decoration panel. Summary of the invention

[0005] 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.

[0008] Furthermore, the linkage assembly includes linkage grooves provided on the first alignment block and the second alignment block, linkage blocks are symmetrically slidably installed in the linkage grooves, a second spring is commonly installed between the linkage blocks and the linkage grooves, and the side walls on the adjacent sides of the two linkage blocks are inclined surfaces, an installation groove is provided on the side walls of the linkage grooves, and a push rod is slidably installed in the installation grooves.

[0009] Furthermore, a cavity is provided on the linkage block, an air hole is provided on the cavity, a horizontal plate is fixedly installed on the mounting plate, an elastic pad is installed between the horizontal plate and the bottom plate, an air cavity is provided on the elastic pad, a first air pipe is inserted into the air cavity, a control component is provided on the linkage block, and an end of the first air pipe away from the air cavity is connected to the cavity through the control component.

[0010] 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.

[0011] Furthermore, an electromagnetic valve whose input end is connected to the outside is inserted in the cavity, and the electromagnetic valve is electrically connected to the heating wire. An exhaust valve is inserted in the cavity, a guide groove is opened on the mounting plate, and a guide hole is opened on the side wall of the guide groove.

[0012] Furthermore, a groove is provided on the horizontal plate, a sealing rod is slidably installed in the groove, a third spring is installed between the sealing rod and the horizontal plate, a connecting groove is provided on the sealing rod, and the connecting groove is connected to the output end of the exhaust valve, and a guide pipe connected to the guide groove is inserted into the groove.

[0013] Furthermore, an insulation box cooperating with the mounting plate is installed on the bottom wall of the top plate.

[0014] Furthermore, a roller is rotatably mounted on one end of the push rod away from the linkage block.

[0015] Compared with the prior art, the present invention has the following beneficial effects: (1) In this scheme, the magnet block cooperates with the coil. The coil is energized and generates an electromagnetic field. Under the action of the electromagnetic field, the magnet block drives the mounting rod to move along the slide groove and stretches 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, the first alignment block 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 veneer material, thereby improving the covering effect. (2) In this scheme, a linkage block is provided. When the first clamping block drives the interior 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 wall of the interior panel. As the first clamping block moves, the interior panel applies a thrust to the two push rods. Then, under the action of the thrust, the push rods move along the installation groove. During the movement of the push rods, the push rods gradually contact the inclined surface of the linkage block and apply a thrust to 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, the linkage block gradually contacts the inner wall of the front and rear sides of the interior panel and applies a thrust to the inner wall of the front and rear sides. Then, under the action of the thrust, the interior panel can be adjusted to the front and rear positions, thereby further ensuring that the interior panel is aligned with the veneer material, and further improving the covering effect. (3) In this scheme, by opening a cavity and an air hole, the elastic pad is stretched and has a tendency to recover during the process of the electric telescopic rod contracting and driving the bottom plate to approach the top plate. In addition, during the process of the elastic pad being stretched, the gas pressure in the air cavity decreases and has a tendency to absorb air from the outside. Then, after the linkage block straightens the interior panel, the second spring reaches the maximum compression degree, and at this time, the linkage block drives the connecting hole to connect with the second air pipe. At this time, the air cavity absorbs air from the cavity through the first air pipe, the connecting hole, and the second air pipe, and restores the cavity. Then, the cavity has a tendency to absorb air from the outside through the air hole. Since the side wall of the linkage block fits with the inner wall of the inner side wall at this time, the inner wall of the interior panel blocks the air hole. Therefore, under the action of the gas pressure in the cavity, the linkage block and the inner wall of the interior panel are tightly sucked together, thereby preventing the interior panel from moving during the covering process and affecting the covering effect, thereby further improving the covering effect. (4) In this scheme, a guide groove is provided. When the electric telescopic rod is extended and drives the bottom plate to reset, the elastic pad contracts. At this time, the gas pressure in the air cavity increases. When the bottom plate moves downward, it gradually contacts the sealing rod and applies a downward thrust to the sealing rod. Then, under the action of the thrust, the sealing rod moves downward and stretches the third spring. After the bottom plate is reset, the sealing rod drives the connecting groove to connect with the guide pipe. At this time, the air flow in the air cavity flows into the guide groove through the exhaust valve, the connecting groove, and the guide pipe, and is blown toward the interior panel that has been wrapped through the guide holes on the guide groove, thereby accelerating the air flow rate at the interior panel wrapping, thereby accelerating the cooling rate of the glue at the wrapping, and further improving the wrapping efficiency.

[0020] The linkage assembly 11 includes linkage grooves provided on the first aligning block 104 and the second aligning block 105, linkage blocks 111 are symmetrically slidably installed in the linkage grooves, a second spring 112 is installed between the linkage block 111 and the linkage grooves, and the side walls of the adjacent sides of the two linkage blocks 111 are inclined surfaces, an installation groove is provided on the side wall of the linkage groove, and a push rod 113 is slidably installed in the installation groove.

[0021] In the initial state, the first spring 103 is in a freely extended state. When in use, the interior panel is first placed on the top wall of the bottom plate 5, and the alignment component 10 is located inside the interior 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 slide groove and stretches the first spring 103. During the movement of the mounting rod 102, the first alignment block 104 can be driven to move. During the movement of the first alignment block 104, it gradually contacts the inner wall of the interior panel and drives the interior panel to move. Then, during the movement of the interior panel, the side wall of the interior 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 panel in the left and right directions and clamp the interior panel. Then the user can control the motor 4 to rotate. The electric telescopic rod 7 is then retracted to move the bottom plate 5 downward, and the interior panel is then moved downward to gradually fit with the bonding material, thereby achieving the purpose of coating the interior panel with the veneer material. The first alignment block 104 and the second alignment block 105 can be used to adjust the left and right positions of the interior panel, so that the interior panel is located directly below the mounting plate 8 and is aligned with the veneer material, thereby improving the coating effect.

[0022] When the first clamping block drives the interior 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 walls of the interior panel, and as the first clamping block moves, the interior panel will apply a thrust to the two push rods 113, and then the push rods 113 move along the installation groove under the action of the thrust, and gradually contact the inclined surface of the linkage block 111 during the movement of the push rods 113, and apply a thrust to the inclined surface of the linkage block 111, and then the linkage block 111 moves out of the linkage groove under the action of the thrust, at this time the second spring 112 is compressed and has a tendency to recover, and gradually contact the inner side walls of the front and rear sides of the interior panel during the movement of the linkage block 111 out of the linkage groove, and apply a thrust to the inner side walls of the front and rear sides, and then the interior panel can be adjusted front and rear under the action of the thrust, thereby further ensuring that the interior panel is aligned with the veneer material, further improving the covering effect.

[0023] like Figure 3 , Figure 7 As shown, a cavity 121 is provided on the linkage block 111, an air hole 122 is provided on the cavity 121, a horizontal plate 123 is fixedly installed on the mounting plate 3, an elastic pad 124 is installed between the horizontal plate 123 and the bottom plate 5, an air cavity 125 is provided 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 an end of the first air pipe 126 away from the air cavity 125 is connected to the cavity 121 through the control component 127.

[0024] The control assembly 127 includes a communication hole 1271 formed on the linkage block 111 , and the communication hole 1271 is in communication with the first air pipe 126 . A second air pipe 1272 in communication with the cavity 121 is inserted into the communication hole 1271 .

[0025] By adopting the above technical solution, when the electric telescopic rod 7 is contracted 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 when the elastic pad 124 is stretched, the gas pressure in the air cavity 125 is reduced, and there is a tendency to inhale air from the outside, and 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, and at this time the air cavity 125 is compressed through the first air pipe 12 6. The connecting hole 1271 and the second air pipe 1272 draw air from the cavity 121 and restore the cavity 121. Then the cavity 121 tends to draw air from the outside through the air hole 122. Since the side wall of the linkage block 111 fits with the inner wall of the inner wall at this time, the inner wall of the interior panel blocks the air hole 122. Therefore, under the action of the gas pressure in the cavity 121, the linkage block 111 and the inner wall of the interior panel are tightly sucked together, thereby avoiding the movement of the interior panel during the covering process, affecting the covering effect, and further improving the covering effect.

[0026] like Figure 6 , Figure 7 As shown, the cavity 121 is provided with an electromagnetic valve 131 whose input end is connected to the outside, and the electromagnetic valve 131 is electrically connected to the heating wire, the cavity 121 is provided with an exhaust valve 132, the mounting plate 3 is provided with a guide groove 133, and the side wall of the guide groove 133 is provided with a guide hole 134.

[0027] The horizontal plate 123 is provided with a groove, in which a sealing rod 135 is slidably installed, and a third spring 136 is installed between the sealing rod 135 and the horizontal plate 123. The sealing rod 135 is provided with a connecting groove 137, and the connecting groove 137 is connected to the output end of the exhaust valve 132. A guide pipe 138 connected to the guide groove 133 is inserted in the groove.

[0028] By adopting the above technical solution, when the heating wire 9 is energized and heats the veneer material, the solenoid valve 131 is energized and in a closed state. Then, when the veneer is completed, the user can first control the mounting plate 3 to reverse through the motor 4, and then drive the top plate 6 and the bottom plate 5 to reverse during the reversal of the mounting plate 3, so that the bottom plate 5 is located at the bottom again. After the reversal is completed, the user can turn off the heating wire 9. At this time, the solenoid valve 131 is powered off and in an open state. Since the elastic pad 124 is in a stretched state, the air cavity 125 inhales 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, and then the electric telescopic rod 7 and the motor 4 are powered off. At this time, the elastic pad 124 contracts and drives the bottom plate 5 The bottom plate 5 is reset downward, and the interior panel and the top plate 6 are gradually moved away from each other during the process of the bottom plate 5 being reset downward. At the same time, the electromagnetic field of the coil 106 is disconnected and disappears. Then the first spring 103 contracts and drives the mounting rod 102 to reset. During the process of the mounting rod 102 being reset, the first alignment block 104 is reset. During the process of the first alignment block 104 being reset, the push rod 113 is gradually disengaged from the interior 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 reset through the inclined surface. After the first alignment block 104 is reset, the fixing effect of the interior panel is released, thereby facilitating the user to remove the interior panel, thereby improving the covering efficiency.

[0029] Then, when 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 cavity 125 increases. In the process of the bottom plate 5 moving 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 connect with the guide pipe 138. At this time, the air flow 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 wrapped through the guide hole 134 on the guide groove 133, thereby accelerating the air flow rate at the coating of the interior panel, thereby accelerating the cooling rate of the glue at the coating, and further improving the coating efficiency.

[0030] like Figure 8 As shown, a heat preservation box 14 matching with the mounting plate 8 is installed on the bottom wall of the top plate 6 .

[0031] By adopting the above technical solution and setting up the insulation box 14, the interior panel covering can be insulated and a constant temperature environment can be provided for the interior panel covering, thereby avoiding a large temperature difference when the interior panel is covered, affecting the covering effect, and improving the covering effect.

[0032] like Figure 2As shown, a roller 16 is rotatably mounted on one end of the push rod 113 away from the linkage block 111 .

[0033] By adopting the above technical solution, during the process of the linkage block 111 aligning the interior panel, since the push rod 113 is in contact with the inner wall of the interior panel, sliding friction will occur between the push rod 113 and the interior panel during the movement of the interior panel. By providing the roller 16, the push rod 113 will drive the roller 16 to contact the interior panel instead of the push rod 113, and then drive the roller 16 to roll when the interior panel moves, thereby converting the sliding friction between the interior panel and the push rod 113 into rolling friction between the interior panel and the roller 16, thereby reducing the wear of the interior panel and reducing the resistance of the interior panel when it moves back and forth, thereby ensuring that the linkage block 111 can normally drive the interior panel to move.

[0034] Working principle: In the initial state, the first spring 103 is in a free extension state. When in use, the interior panel is first placed on the top wall of the bottom plate 5, and the alignment component 10 is located inside the interior panel. Then the user can start the motor 4. 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 slide groove and stretch the first spring 103. During the movement of the mounting rod 102, the first alignment block 104 can be driven to move. During the movement of the first alignment block 104, it gradually contacts the inner wall of the interior panel and drives the interior panel to move. Then, during the movement of the interior panel The side wall of the middle interior panel away from the first aligning block 104 gradually contacts the second aligning block 105. At this time, the first aligning block 104 and the second aligning block 105 can align the interior panel in the left and right directions and clamp the interior panel. Then the user can control the motor 4 to rotate 180 degrees. During the rotation of the motor 4, the mounting plate 3 is driven 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 veneer 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 veneer material and melt the glue on the veneer material. The user can control the electric telescopic rod 7 to retract, and during the process of the electric telescopic rod 7 retracting, the bottom plate 5 is driven to move downward, and during the process of the bottom plate 5 moving downward, the interior panel is driven to move downward and gradually fit with the bonding material, thereby achieving the purpose of covering the veneer material on the interior panel, and by setting the first aligning block 104 and the second aligning block 105, the position of the interior panel in the left and right directions can be adjusted, so that the interior panel is located directly below the mounting plate 8; when the first clamping block drives the interior panel to contact the second clamping block, the first clamping block and the second clamping block respectively drive the corresponding push rod 113 to contact the inner side wall of the interior panel, and as When the first clamping block moves, the interior panel applies thrust to the two push rods 113, and then the push rods 113 move along the installation groove under the action of the thrust, and gradually contact the inclined surface of the linkage block 111 during the movement of the push rods 113, and apply thrust to the inclined surface of the linkage block 111, and then the linkage block 111 moves out of the linkage groove under the action of the thrust, at this time, the second spring 112 is compressed and has a tendency to recover, and gradually contact the inner side walls of the front and rear sides of the interior panel during the movement of the linkage block 111 out of the linkage groove, and apply thrust to the inner side walls of the front and rear sides, and then the interior panel can be adjusted to the front and rear position under the action of the thrust;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. ;

[0035] The above is only a preferred specific implementation of the present invention; however, 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 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.
