Technical Field

[0001] The invention relates to the technical field of gluing devices, and in particular to a gluing device for automobile interior trim sheet members. Background Art

[0002] The automobile interior as a whole includes many decorative panels, including PU panels, GMT panels and hemp fiber panels, etc. When bonding the exterior decorative fabrics, it is usually divided into two processes: gluing and pressing and edge covering. However, in the prior art, during the gluing and pressing of automobile interior panels, it is found that there are often a small amount of bubbles between the interior panels and the decorative fabrics, resulting in partial leakage and hollowing. In addition, during the transfer to the edge covering process, the adhesive on the edge dries up, which reduces the adhesion between the interior panels and the decorative fabrics. In addition, the production is carried out in separate processes, and the processing efficiency needs to be improved. Summary of the invention

[0014] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0015] like Figures 1 to 3 As shown, a bonding device for automobile interior panel parts includes a frame 1, a mounting frame 2 and a pressing and hemming mechanism 3. The frame 1 is bolted with a "π"-shaped storage seat 4, the mounting frame 2 is fixedly mounted on the frame 1, and the inner side wall of the mounting frame 2 is provided with a slide groove 1 21 and two symmetrically arranged slide grooves 22. The pressing and hemming mechanism 3 is installed on the mounting frame 2 and is used for gluing and pressing the panel parts and hemming and pressing the edges.

[0016] In this embodiment, the pressing and hemming mechanism 3 includes a driving motor 31, a crank 32 and a pressing piece 33. The driving motor 31 is installed on the mounting frame 2, and the crank 32 is installed on the output end of the driving motor 31. A slip ring 34 is slidably provided at the other end of the crank 32. Two symmetrically arranged sliding rods 35 are fixed at the lower end of the slip ring 34. The pressing piece 33 is slidably provided on the sliding rod 35. The side end of the pressing piece 33 is slidably provided in the slide groove 22. A spring 36 is sleeved on the slide rod 35 between the slip ring 34 and the pressing piece 33. A pushing piece 37 is also fixed to the middle part of the lower end of the slip ring 34. The other end of the pushing piece is slidably provided in the slide groove 1 21. Two symmetrically arranged rotating plates 38 are rotatably provided on the pressing piece 33, and an hemming roller 39 is fixed at the lower end of the rotating plate 38.

[0017] It should be noted that the upper end of the storage seat 4 is a groove-shaped structure, and the width of the storage seat 4 is not greater than the minimum distance between the two hemming rollers 39 .

[0018] In this embodiment, the lower end of the pressing member 33 is provided with a raised plane so as to press the upper end of the interior trim panel smoothly.

[0019] In this embodiment, the lower ends of the pushing member 37 are two smooth spherical ends, and the lower ends of the pushing member 37 match the inclined surface of the rotating plate 38 .

[0020] In this embodiment, the upper end surfaces of the two rotating plates 38 are inclined surfaces that are relatively inclined outward, and the weight of the rotating plates 38 is not higher than the weight of the hemming roller 39 .

[0021] Working process and principle: During the use of the present invention, the automobile interior panel to be glued and pressed is first placed on the storage seat 4, and then the driving motor 31 is started so that its output end drives the crank 32 to rotate, so that the end of the crank 32 slides in the slip ring 34, and the push piece 37 and the pressing piece 33 are guided and slide in the slide groove 1 21 and the slide groove 2 22 respectively, so that the slip ring 34 drives the slide rod 35 to move downward synchronously, and the spring 36 pushes the pressing piece 33 to move downward under the action of its own elastic force, and then the lower end convex plane of the pressing piece 33 flattens the upper end surface of the interior panel, and when the hemming roller 39 moves down to below the edge of the storage seat 4, the pressing piece 33 is already on the interior The upper end surface of the plate stops moving downward, and as the slip ring 34 continues to move downward, the lower ball end of the push piece 37 pushes the upper inclined surface of the rotating plate 38, so that the rotating plate 38 drives the hemming roller 39 to rotate in the same direction as the rotation point of the pressing piece 33, thereby exhausting the internal air from the end of the interior decoration plate and further hemming it. During the rising process of the push piece 37, the hemming roller 39 will drive the rotating plate 38 to return to the vertical position again under the action of its own gravity, and finally, with the reciprocating rotation of the crank 32, the above-mentioned actions are repeated to completely eliminate the small amount of bubbles existing in the bonding of the plate, avoid the occurrence of hollowing, and at the same time effectively hem the edge of the interior decoration plate toward the bottom wall.

[0022] Based on the above, the present invention arranges a detachable storage seat 4 on the frame 1, cooperates with the pressing and hemming mechanism 3 arranged on the mounting frame 2, and the output end of the driving motor 31 drives the crank 32 to rotate, and pushes the pressing piece 33 downward through the slip ring 34, the slide rod 35 and the spring 36 respectively, and then the raised plane at the lower end of the pressing piece 33 is used to press the upper end surface of the interior decoration board smoothly. With the reciprocating rotation of the crank 32, a small amount of bubbles existing inside the board bonding can be completely eliminated to avoid the hollowing phenomenon. At the same time, the two hemming rollers 39 rotate towards each other, and the internal air can be discharged from the end of the interior decoration board and further hemming can be achieved. The pressing and hemming processes are completed at a single station, which greatly improves the processing efficiency.
