Description

Technical Field

[0001] This utility model relates to the field of automotive processing technology, specifically to an automotive tailgate processing device and system. Background Technology

[0002] In the automotive manufacturing industry, the processing precision of the tailgate directly determines the assembly quality and reliability of the entire vehicle. Among these processes, the hot-melt process, as the core connection technology between the tailgate frame and the panel, is particularly critical in terms of positioning accuracy. The hot-melt process utilizes the adhesive properties of the molten material to achieve a stable bond between components by heating hot-melt adhesive or the workpiece's inherent hot-melt structure. This is a crucial step in ensuring the structural strength and sealing of the tailgate.

[0003] However, the current hot-melt processing of automotive tailgates faces two prominent problems: firstly, insufficient positioning accuracy in the hot-melt process, and secondly, a lack of stability in the hot-melt equipment itself. Regarding positioning accuracy, the traditional hot-melt process lacks a unified coordinate reference for positioning fixtures used in preceding and following processes such as material loading and mold closing. This results in the tailgate blank failing to accurately align with the hot-melt area when entering the hot-melt station. Consequently, the heating range of the hot-melt lamp often fails to accurately cover the pre-set hot-melt adhesive or hot-melt column area, leading to problems such as insufficient or excessive heating in certain areas.

[0004] Regarding equipment stability, in existing hot-melt processes, the heating of the upper and lower molds is typically accomplished by two independent hot-melt lamps, and the installation positions of these two lamps lack rigid fixing and linkage mechanisms. Due to vibrations, temperature changes, or mechanical wear during long-term operation, the relative positions of the two hot-melt lamps are prone to shift. This instability can cause the heating areas of the upper and lower molds to fail to align synchronously with the corresponding hot-melt points on the tailgate, resulting in one side of the mold being heated to its proper position while the other side is offset.

[0005] The aforementioned issues directly lead to uneven fit clearances, poor sealing strip adhesion, and component mounting hole misalignment during tailgate assembly. This not only increases subsequent manual adjustment costs but also reduces the overall vehicle quality consistency. Therefore, there is an urgent need for a technical solution that can improve the accuracy of hot melt positioning and ensure the stable position of the dual hot melt lamps to overcome the bottlenecks of the existing process. Summary of the Invention

Detailed Implementation

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

[0022] Example 1: See Figure 1As shown, this embodiment provides a car tailgate processing device, which includes: an upper mold assembly 200 and a lower mold assembly 100. The upper mold assembly 200 and the lower mold assembly 100 are movable relative to each other in a vertical direction to press the tailgate blank. The upper mold assembly 200 is provided with at least two upper mold insertion posts 220, which protrude towards the lower mold assembly 100 in the vertical direction. The lower mold assembly 100 is provided with at least two lower mold docking grooves 120, which are recessed away from the upper mold assembly 200 in the vertical direction. A hot melt assembly 300 is provided, which can be connected between the upper mold assembly 200 and the lower mold assembly 100 and is externally connected to a mobile device, including an assembly frame 310. The assembly frame 310 includes an upper mold hot melt lamp 350, a lower mold hot melt lamp 360, and at least two mating parts 340. The upper mold hot melt lamp 350 and the lower mold hot melt lamp 360 are respectively connected to opposite sides of the assembly frame 310 in the thickness direction and are respectively positioned towards the upper mold assembly 200 and the lower mold assembly 100. Each mating part 340 includes a housing 341, a protrusion 342, and a recess 343. The housing 341 extends vertically and its middle part is connected to the assembly frame 310. The protrusion 342 and the recess 343 are respectively located at opposite ends of the housing 341 in the vertical direction. The protrusion 342 can pass through the lower mold mating groove 120, and the upper mold insertion post 220 can pass through the recess 343.

[0023] The automotive tailgate processing device and system described in this utility model can precisely align the upper mold assembly 200, the lower mold assembly 100, and the hot-melt assembly 300. The protrusion 342 can pass through the lower mold docking groove 120, and the upper mold insertion post 220 can pass through the recess 343. Through this insertion and engagement method, the hot-melt assembly 300 is rigidly connected to the upper and lower mold assemblies 100, thereby ensuring the consistency and stability of the hot-melt assembly 300 as a whole during the hot-melt process. Simultaneously, the upper mold hot-melt lamp 350 and the lower mold hot-melt lamp 360 are integrated on the assembly frame 310, thereby ensuring the relative stability of the components within the hot-melt assembly 300. Compared to current conventional hot-melt processing technologies, this application offers advantages such as precise alignment, high degree of structural fit, and stable processing quality.

[0024] In this embodiment, the upper mold assembly 200 includes an upper mold frame 210 connected to an external mobile device, and an upper mold insertion post 220 disposed on the upper mold frame 210. The lower mold assembly 100 further includes a lower mold frame 110 supported on a fixed platform, and a lower mold docking groove 120 disposed on the lower mold frame 110. The upper mold assembly 200 and the lower mold assembly 100 move relative to each other to achieve pressing and positioning of the tailgate blank. The upper mold assembly 200 serves as the supporting foundation for the tailgate blank, providing a stable placement platform for the blank. Its contour typically matches the bottom shape of the tailgate blank, initially limiting the horizontal displacement of the blank. Four lower mold docking grooves 120 are provided at its corners. The upper mold assembly 200 can be moved downward by the external mobile device to apply pressure to the tailgate blank placed on the lower mold assembly 100, achieving a tight fit between the blank and the material. Similarly, four upper mold insertion posts 220 are provided at its corners. During the pressing process, the upper mold insertion posts 220 can be precisely aligned and connected with the lower mold mating groove 120 to ensure the alignment accuracy of the upper mold assembly 200 and the lower mold assembly 100.

[0025] See Figure 1 and Figure 2 As shown, in this embodiment, the hot melt assembly 300 ensures a perfect match between the hot melt position and the processing area of ​​the blank by precisely docking with the upper mold assembly 200 and the lower mold assembly 100. The assembly frame 310, as the basic structure of the hot melt assembly 300, is used to fix the upper mold hot melt lamp 350, the lower mold hot melt lamp 360, and the docking part 340, integrating all components into a whole. This ensures the relative position stability of the hot melt lamp and the docking part 340, avoiding positional displacement caused by vibration or thermal deformation. Simultaneously, the assembly frame 310 connects to external mobile devices such as robotic arms and guide rails to enable the hot melt assembly 300 to enter for processing or exit between the upper mold assembly 200 and the lower mold assembly 100 for avoidance. The upper mold hot melt lamp 350 is connected to one side of the assembly frame 310 in the thickness direction and is used to heat the upper part of the tailgate blank to be melted. The lower mold hot melt lamp 360 is connected to the other side of the assembly frame 310 in the thickness direction and is used to heat the lower part of the tailgate blank to be melted. The lower mold hot melt lamp 360 and the upper mold hot melt lamp 350 work together to ensure that the hot melt areas on the upper and lower sides of the blank melt synchronously, avoiding insufficient bonding strength due to uneven heating.

[0026] The mating parts 340 are used to ensure that the hot melt assembly 300 is accurately positioned with the upper mold assembly 200 and the lower mold assembly 100. Each mating part 340 includes a housing 341, a protrusion 342 and a recess 343. Specifically, the housing 341 extends vertically and is connected to the assembly frame 310 in the middle, providing rigid support for the protrusion 342 and the recess 343 to ensure that their relative positions are fixed. The protrusion 342 is located at the end of the housing 341 facing the lower mold assembly 100 and can pass through the lower mold mating groove 120 to accurately position the lower part of the hot melt assembly 300 with the lower mold assembly 100, ensuring that the heating direction of the lower mold hot melt lamp 360 is completely aligned with the lower part of the blank to be hot melted area. The recess 343 is located at the end of the housing 341 facing the upper mold assembly 200, and can accommodate the upper mold insertion post 220. Through the cooperation with the upper mold insertion post 220, the upper part of the hot melt assembly 300 is precisely positioned with the upper mold assembly 200, ensuring that the heating direction of the upper mold hot melt lamp 350 is completely aligned with the upper part of the blank to be hot melted area.

[0027] Multiple docking parts 340 work together to ensure that the hot melt assembly 300 is rigidly positioned with both the upper mold assembly 200 and the lower mold assembly 100. This ensures that the positions of the upper mold hot melt lamp 350 and the lower mold hot melt lamp 360 strictly correspond to the areas of the blank to be processed, preventing hot melt misalignment. Specifically, in this embodiment, docking parts 340 are provided at all four corners of the assembly frame 310 to achieve comprehensive support and connection for the assembly frame 310. In different embodiments, the specific number and connection positions of the docking parts can be adaptively adjusted according to actual usage requirements, and this utility model does not impose specific limitations in this regard.

[0028] In this embodiment, the hot melt assembly 300 further includes an assembly plate 333 and multiple module frames 330. One side of the assembly plate 333 is detachably connected to the assembly frame 310, and the other side is detachably connected to multiple module frames 330. Multiple lower mold hot melt lamps 360 are respectively connected to multiple module frames 330. Specifically, each module frame 330 includes an extension 331 and a connecting plate 332. The extension 331 extends vertically, with one end connected to the assembly plate 333 and the other end connected to the connecting plate 332. The lower mold hot melt lamps 360 are hooked onto the connecting plate 332. The assembly plate 333 serves as an intermediate connector 370, detachably connected to the assembly frame 310 on one side and detachably connected to multiple module frames 330 on the other side, thus achieving an indirect connection between the lower mold hot melt lamps 360 and the assembly frame 310. This detachable design facilitates quick replacement of different specifications of the module frame 330 or the lower mold hot melt lamp 360, adapting to the heating requirements of different tailgate blanks.

[0029] The extension 331 extends vertically, connecting one end to the assembly plate 333 and the other end to the connecting plate 332. Its length design supports the lower mold hot melt lamp 360 to a preset height near the lower surface of the tailgate blank, compensating for the spatial distance between the assembly plate 333 and the blank. The extension 331 can be designed as a straight rod or a slightly curved structure according to the heating angle requirements, ensuring that the light from the lower mold hot melt lamp 360 is focused on the target area of ​​the blank. The connecting plate 332, as the direct mounting carrier for the lower mold hot melt lamp 360, enables rapid fixing of the hot melt lamp. In summary, the assembly plate 333 and multiple module frames 330 form a modular heating unit. The assembly plate 333 ensures the installation consistency of all module frames 330 through a unified benchmark. The extension 331 of the module frame 330 precisely delivers the lower mold hot melt lamp 360 to the heating station through spatial positioning, while the connecting plate 332 achieves rapid lamp configuration through a flexible hook structure. This design ensures the accuracy of the heating position, achieves equipment versatility through modularity, and simplifies the maintenance process.

[0030] Correspondingly, the hot melt assembly 300 also includes a support plate 320. The support plate 320 and the assembly plate 333 are respectively disposed on both sides of the assembly frame 310 in the thickness direction. The upper mold hot melt lamp 350 is connected to the support plate 320. The support plate 320, the assembly frame 310, and the assembly plate 333 are detachably connected by a connector 370. The support plate 320 serves as the direct mounting carrier for the upper mold hot melt lamp 350, providing it with a stable fixing foundation. It can also be configured with a structure similar to the module frame 330 of the lower mold assembly 100. This utility model does not specifically limit its specific structural design.

[0031] See Figure 3 As shown, any of the docking parts 340 further includes two fixing blocks 344, which are respectively disposed at both ends of the housing 341 in the vertical direction. The recessed portion 343 is disposed on the fixing block 344 near the upper mold assembly 200 and is recessed in the vertical direction away from the upper mold assembly 200. The protruding portion 342 is connected to the fixing block 344 near the lower mold assembly 100 and extends in the vertical direction towards the upper mold assembly 200.

[0032] Two fixing blocks 344 are respectively disposed at both ends of the housing 341 in the vertical direction, forming a symmetrical support structure that enhances the overall rigidity of the mating parts 340. The fixing block 344 near the upper mold assembly 200 supports the recessed portion 343, and the fixing block 344 near the lower mold assembly 100 supports the protruding portion 342. The solid structure disperses the force during insertion, preventing the housing 341 from deforming due to excessive local stress. Furthermore, the fixing blocks 344 provide a stable mounting reference for the recessed portion 343 and the protruding portion 342. The recessed portion 343 is recessed in the vertical direction away from the upper mold assembly 200, precisely matching the vertical protrusion direction of the upper mold insertion post 220, ensuring that the upper mold insertion post 220 is inserted without offset; the protruding portion 342 extends upward in the vertical direction after passing through the fixing block 344, corresponding to the vertical recess direction of the lower mold mating groove 120, further improving the mating accuracy between the hot melt assembly 300 and the upper and lower molds. Furthermore, the hot melt assembly 300 in this embodiment also includes a reinforcing bracket 346, through which at least some of the mating parts 340 are connected, so as to further improve the overall stability of the hot melt assembly 300.

[0033] Furthermore, the docking member 340 also includes at least one limiting baffle 345, which is connected to one side of the fixing block 344 and extends along the vertical direction away from its corresponding housing 341 to stop the upper mold assembly 200 or the lower mold assembly 100 in its thickness direction. The limiting baffle 345, connected to one side of the fixing block 344 and extending vertically, can directly stop excessive movement of the upper mold assembly 200 and the lower mold assembly 100 in the thickness direction when they move relative to each other. This design can precisely control the horizontal position between the upper mold assembly 200, the hot melt assembly 300, and the lower mold assembly 100. The limiting baffle 345 is provided with a plurality of adjusting positioning holes 3451, which are spaced apart along the extending direction of the limiting baffle 345. The connecting member 370 is connected to the fixing block 344 through the adjusting positioning holes 3451. In different implementations, the actual extension length of the limiting baffle 345 can be adjusted by the connector 370 and the adjusting positioning hole 3451 to improve its flexibility of use.

[0034] Example 2:

[0035] This embodiment provides a car tailgate processing system, which includes the above-mentioned car tailgate processing device.

[0036] In summary, the automotive tailgate processing device and system described in this utility model can precisely align the upper mold assembly 200, the lower mold assembly 100, and the hot-melt assembly 300. The protrusion 342 can pass through the lower mold docking groove 120, and the upper mold insertion post 220 can pass through the recess 343. Through this insertion and engagement method, the hot-melt assembly 300 is rigidly connected to the upper and lower mold assemblies 100, thereby ensuring the consistency and stability of the hot-melt assembly 300 as a whole during the hot-melt process. Simultaneously, the upper mold hot-melt lamp 350 and the lower mold hot-melt lamp 360 are integrated on the assembly frame 310, thereby ensuring the relative stability of each component in the hot-melt assembly 300. Compared with current conventional hot-melt processing technologies, this application has advantages such as precise alignment, high degree of fit between structures, and stable processing quality.

[0037] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description.

However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
