[0079] The upper end surface of the positioning seat 601 is inclined at 30°-45° relative to the horizontal plane.

[0080] The positioning cylinder 602 is disposed on the positioning seat 601. The positioning guide rail 603 is disposed on the positioning seat 601 and is also disposed at an angle of 30°-45° relative to the horizontal plane.

[0081] The positioning block 604 is located on the side of the first side portion 701 , is slidably connected to the positioning rail 603 , and is connected to the positioning cylinder 602 through the connecting plate 605 , and is used to slide along the positioning rail 603 driven by the positioning cylinder 602 .

[0082] The material fixing edge portion can clamp two opposite side edges of the laminating material 8 , and at this time, the hot melt adhesive layer of the laminating material 8 faces upward.

[0083] The heating unit is configured using conventional technology, for example, a horizontally movable heating unit. Prior to lamination, it can be moved horizontally between the material fixing and hemming unit and the frame fixing unit 1 to melt the hot melt adhesive layer on the laminating material 8. The heating unit then moves horizontally to the side, leaving space for the laminating material 8 to be laminated with the automotive interior frame 7. A control unit 10 is used to control the movement of the heating unit, the material fixing and hemming unit, and the frame fixing unit 1 to complete the laminating and hemming operation of the automotive interior frame 7.

[0084] Under the control of the control unit 10, the process of laminating and hemming the upper rear interior trim of the C-pillar of the automobile by the laminating and hemming device 100 is as follows:

[0085] Step 1, when the control unit 10 is in the initial state, the control unit 10 controls the first clamping block 3021 and the first edging block 3022 to cooperate to clamp the cladding material 8 corresponding to the first side 701, the second clamping block 401 and the second edging block 402 to cooperate to clamp the cladding material 8 corresponding to the second side 702, and the third clamping block 5011 and the third edging block 5012 to cooperate to clamp the cladding material 8 corresponding to the third side 703, so that the cladding material 8 is in a horizontal state.

[0086] In step 2, the control unit 10 controls the heating unit to move horizontally from its waiting position to between the material fixing edge portion and the frame fixing portion 1, thereby melting the hot melt adhesive layer on the laminating material 8, and then moves horizontally back to the waiting position next to it.

[0087] Step 3, laminating the automobile interior frame 7 with the laminating material 8, specifically includes the following sub-steps:

[0088] S3 - 1 : the control unit 10 controls the moving driving unit 105 to drive the moving plate 101 to bring the automobile interior frame 7 down, so that the automobile interior frame 7 gradually approaches the cladding material 8 .

[0089] Figure 9 1 is a schematic diagram of a first state of a laminating and edging device for an upper rear interior trim part of a C-pillar of an automobile according to an embodiment of the present invention when laminating and edging is performed.

[0090] S3-2: If Figure 9 As shown, when the automobile interior frame 7 descends to contact the cladding material 8, the control unit 10 simultaneously controls the first horizontal drive component 3027 to drive the first horizontal moving component 3026 at a first predetermined speed, and the second horizontal drive component 407 to drive the second horizontal moving component 406 at a second predetermined speed toward the direction close to the automobile interior frame 7 to a preset position, thereby simulating manual loosening. In this embodiment, the first moving speed and the second moving speed are equal. At this time, the third push rod 104 also contacts the third matching rod 502, pushing the third clamping block 5011 and the third edging block 5012 to descend at the same descending speed as the movable plate 101 and the automobile interior frame 7. Thereafter, the automobile interior frame 7 continues to move downward.

[0091] Figure 10 1 is a schematic diagram of a second state of the automobile C-pillar rear upper interior trim laminating and hemming device 100 during laminating and hemming according to an embodiment of the present invention. Figure 11 1 is a schematic diagram of a third state of the automobile C-pillar rear upper interior trim laminating and hemming device 100 during laminating and hemming according to an embodiment of the present invention.

[0092] When the automobile interior frame 7 moves down by a height of △h from the height just contacting with the cladding material 8, Figure 10 As shown, the first push rod 103 contacts the first matching rod 301, and the first clamping block 3021 and the first edge block 3022 descend at the same descending speed as the moving plate 101 and the automobile interior frame 7 until the cladding material 8 is pressed onto the supporting mold 201, so that the cladding material 8 is laminated with the automobile interior frame 7. Figure 11 During this process, the first horizontal moving assembly 3026 always moves at a first predetermined speed, and the second horizontal moving assembly 406 always moves at a second predetermined speed toward the direction of the automobile interior frame 7. The third clamping block 5011 and the third edge-wrapping block 5012 always continue to descend at the same descending speed as the moving plate 101 and the automobile interior frame 7 until the lamination is complete. Figure 11 The status shown.

[0093] Step 4, wrapping the cladding material 8 on the edge of the automobile interior frame 7, specifically includes the following sub-steps:

[0094] S4 - 1 : The control unit 10 controls the positioning cylinder 602 to drive the positioning block 604 to slide along the positioning guide rail 603 , so that the cladding material 8 on the side of the first side portion 701 presses against the edge of the outer bend portion A of the first side portion 701 .

[0095] S4-2: The control unit 10 simultaneously controls the first flipping drive assembly 3023 to drive the first clamping block 3021 to rotate, the second flipping drive assembly 403 to drive the second clamping block 401 to rotate, and the third displacement drive assembly 5014 to drive the third displacement assembly 5013 to drive the third clamping block 5011 away from the third edging block 5012 to loosen the laminating material 8.

[0096] S4-3: The control unit 10 simultaneously controls the first horizontal driving component 3027 to drive the first horizontal moving component 3026 to drive the first edging block 3022, and the second horizontal driving component 407 to drive the second horizontal moving component 406 to drive the second edging block 402 to move toward the direction close to the automobile interior frame 7, pushing the edges of the laminated material 8 corresponding to the first side 701 and the second side 702 to the inner side of the automobile interior frame 7.

[0097] S4-4: The control unit 10 simultaneously controls the first oblique driving component 3025 to drive the first oblique driving component 3024 to drive the first edging block 3022 to descend, the second vertical driving component 405 to drive the second vertical driving component 404 to drive the second edging block 402 to descend, and the third oblique driving component 5016 to drive the third oblique driving component 5015 to drive the third edging block 5012 to move to edge the automobile interior frame 7, so that the edge of the laminating material 8 is wrapped on the inner surface of the automobile interior frame 7.

[0098] Functions and Effects of the Embodiments

[0099] According to the present invention, the laminating and edging device 100 for the rear upper interior trim of an automobile C-pillar is provided with a support portion 2, a material fixing and edging portion, and a frame fixing portion 1 that cooperate with each other. The movement of the material fixing and edging portion and the frame fixing portion 1 is controlled by a control portion 10 to complete the entire laminating and edging operation, ensuring processing consistency. The laminating material 8 is initially in a horizontal state and is always clamped by the various clamping blocks and edging blocks during the laminating process, preventing positional deviation and ensuring edging accuracy. The entire laminating and edging process does not require manual operation, saving labor costs and shortening overall operation time, making it suitable for industrial applications.

[0100] By setting the first material fixing edging mechanism 3, the second material fixing edging mechanism 4 and the third material fixing edging mechanism 5, the first edge 701, the second edge 702 and the third edge 703 of the automobile interior frame 7 with different heights can be more accurately matched for laminating and edging, thereby improving the laminating and edging accuracy.

[0101] By arranging the first cylinder 303, the first push rod 103, the third cylinder 503, and the third push rod 104, the first clamping block 3021, the first hemming block 3022, the third clamping block 5011, and the third hemming block 5012 can descend at the same speed as the movable plate 101. Furthermore, the length of the first push rod 103 is shorter than that of the third push rod 104, meaning that the descending distance is adjusted according to the height of the different edges, ensuring accurate lamination of the cladding material 8 with the automotive interior frame 7 and ensuring the precision of the lamination process.

[0102] By setting the first horizontal moving component 3026 to drive the first clamping block 3021 and the first edging block component 3022 to move at a first predetermined speed, and the second horizontal moving component 406 to drive the second clamping block 401 and the second edging block 402 to move at a second predetermined speed, manual loosening of the material is simulated, so that the laminating material 8 can be easily matched with the shape of the automobile interior frame 7 during the laminating process, thereby avoiding the laminating material 8 from being torn.

[0103] By setting up the auxiliary edging mechanism 6, the cladding material 8 can be placed against the edge of the automobile interior frame 7 first, avoiding the situation where the cladding material 8 does not fit the edge of the automobile interior frame 7, facilitating the subsequent edging work and ensuring the edging accuracy.

[0104] Those skilled in the art will appreciate that the present invention is not limited to the foregoing embodiments. The foregoing embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and modifications may be made to the present invention without departing from the spirit and scope of the present invention.
