Description

Technical Field

[0001] The present invention relates to the technical field of hot press coating for automotive parts, and particularly to a hot press coating device for automotive parts. Background Art

[0002] The hot press coating of automotive parts is a process widely used in the manufacturing of automotive interior parts. It is mainly used to improve the texture and aesthetics of interior parts. It includes multiple steps such as cutting, sewing, spraying glue, pre-coating with fixed lines, pressing, and corner wrapping.

[0003] Currently, in the pressing step of the hot press coating process for automotive parts, the existing contact molding can only adhere the fabric and foam to one side surface of the automotive part, but cannot wrap the fabric and foam around the edges of the automotive part. Therefore, it is necessary to consume additional physical strength of workers to wrap and cut the edges, reducing the production efficiency. At the same time, the placement of automotive parts that need to be hot press coated currently is likely to cause inaccurate positioning or deformation of the object due to clamping, affecting the quality and reducing the product quality. Therefore, a hot press coating device for automotive parts is proposed. Summary of the Invention

[0004] Based on the technical problem that in the existing hot press coating of automotive parts, the pressing step can only coat one side of the automotive part and cannot coat its edges, and it is also likely to cause inaccurate positioning or deformation of the object due to clamping, affecting the quality, the present invention proposes a hot press coating device for automotive parts.

Specific implementation manner

[0050] 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.

[0051] Refer to Figures 1-17 , an automotive part hot pressing and coating equipment, including an operating platform 1 and a frame 2 arranged on the upper surface of the operating platform 1. A placement groove 3 for placing automotive parts is opened on the upper surface of the operating platform 1. An adhesive application mechanism is arranged on the upper surface of the operating platform 1, a hot pressing mechanism is arranged on the surface of the frame 2, and a positioning mechanism and a edge wrapping mechanism are respectively arranged on the inner wall of the placement groove 3.

[0052] Among them, in order to position the automotive parts in the placement groove 3, the set positioning mechanism includes a support plate 6 fixedly installed inside the operating platform 1. A set of pushing cylinders is symmetrically distributed left and right on the upper surface of the support plate 6. The set of pushing cylinders consists of two pushing cylinders 601. The piston rods of the set of pushing cylinders are fixedly connected with a T-shaped plate 602. A positioning plate 603 is arranged on the upper surface of the T-shaped plate 602. A set of positioning columns 604 is symmetrically distributed front and back on the upper surface of the positioning plate 603. Two through grooves 605 are opened on the inner wall of the placement groove 3. The surfaces of the positioning plate 603 and the T-shaped plate 602 are both slidably connected with the inner wall of the through groove 605. By the telescopic movement of the piston rod of the pushing cylinder 601, the T-shaped plate 602 connected thereto moves up and down. The up and down movement of the T-shaped plate 602 drives the positioning plate 603 to move up and down along the inner wall of the through groove 605. The up and down movement of the positioning plate 603 drives the positioning columns 604 to move up and down.

[0053] In order to connect the positioning plate 603 to the T-shaped plate 602, so as to facilitate driving the movement of the positioning plate 603 by the movement of the T-shaped plate 602, a stepping motor 606 is fixedly installed on one side surface of the T-shaped plate 602. A rotating shaft 607 is installed on the inner wall of the T-shaped plate 602 through a bearing. One end of the output shaft of the stepping motor 606 is fixedly sleeved with one end of the rotating shaft 607. Two cams 608 are fixedly sleeved on the surface of the rotating shaft 607. Two sliding grooves 609 are formed on the upper surface of the T-shaped plate 602. A clamping post 610 is slidably clamped on the inner wall of the sliding groove 609. Two clamping grooves 611 are formed on the lower surface of the positioning plate 603. The surface of the clamping post 610 is slidably connected to the inner wall of the clamping groove 611. The rotation of the output shaft of the stepping motor 606 drives the connected rotating shaft 607 to rotate. The rotation of the rotating shaft 607 drives the cam 608 to rotate, so that the cam 608 drives the clamping post 610 to move upward along the inner wall of the sliding groove 609 and be clamped with the clamping groove 611, thus facilitating the contraction of the pushing cylinder 601 to drive the positioning plate 603 and the positioning post 604 to move downward along the inner wall of the through groove 605 and be received into the operating table 1.

[0054] In order to drive the movement of the positioning plate 603 so that the positioning post 604 contacts the automotive parts, an electric telescopic rod group is symmetrically arranged on the inner wall of the operating table 1. The electric telescopic rod group is composed of two electric telescopic rods 612. One end of the electric telescopic rod group extends into the placement groove 3 and is fixedly installed with a first magnet 613. Two slots 614 are formed on the surface of the positioning plate 603. A second magnet 615 is fixedly installed on the inner wall of the slot 614. Through the adsorption of the first magnet 613 and the second magnet 615 on the electric telescopic rod 612, it is convenient for the telescopic movement of the electric telescopic rod 612 to drive the movement of the positioning plate 603.

[0055] By setting the positioning mechanism, it is convenient to position the automotive parts placed in the placement groove 3, avoid position deviation when the foam is hot-pressed and coated on the automotive parts, thereby improving the product coating efficiency and product quality.

[0056] Among them, in order to put the hot melt adhesive on the automotive parts in the placement groove 3, the glue application mechanism provided includes a self-driven slide rail 4 fixedly installed on the upper surface of the operating table 1. An installation housing 41 is fixedly installed on the surface of the slider of the self-driven slide rail 4. A rotating motor 42 is fixedly installed on the inner wall of the installation housing 41. One end of the output shaft of the rotating motor 42 passes through the installation housing 41 and is fixedly sleeved with a turntable 43. The bottom of the turntable 43 is installed on the upper surface of the installation housing 41 through a bearing. The rotation of the output shaft of the rotating motor 42 drives the connected turntable 43 to rotate. The movement of the slider on the self-driven slide rail 4 drives the connected installation housing 41 to move.

[0057] In order to pick up hot melt adhesive, a support sleeve rod 44 is fixedly installed on the upper surface of the turntable 43. A driving motor 45 is fixedly installed on the inner wall of the support sleeve rod 44. A screw rod 46 is installed on the inner wall of the support sleeve rod 44 through a bearing. One end of the output shaft of the driving motor 45 is fixedly sleeved with one end of the screw rod 46. A moving sleeve rod 47 is threadedly sleeved on the surface of the screw rod 46. Two electric lifting rods 48 are fixedly installed on the lower surface of the moving sleeve rod 47. A pneumatic gripper 49 is fixedly installed on the lower surface of the electric lifting rod 48. The rotation of the output shaft of the driving motor 45 drives the screw rod 46 connected thereto to rotate. The rotation of the screw rod 46 drives the moving sleeve rod 47 to move along the inner wall of the support sleeve rod 44. The telescopic movement of the electric lifting rod 48 drives the pneumatic gripper 49 to move up and down. The pneumatic gripper 49 places the picked-up hot melt adhesive on the automotive parts.

[0058] By setting up the gluing mechanism, it is convenient to apply glue to the surface of the automotive parts placed in the placement groove 3, and the hot melt adhesive melts with heating, so that it is convenient for the foam to adhere to the automotive parts. As the foam is squeezed, the glue spreads along the surface of the automotive parts, and under the action of the two clamping plates 7, the foam wraps the automotive parts.

[0059] Among them, in order to heat the hot melt adhesive so that the foam fits the upper surface of the automotive parts, the set hot pressing mechanism includes hydraulic cylinders 5 symmetrically distributed and installed on the upper surface of the frame 2. The piston rod of the hydraulic cylinder 5 passes through the upper surface of the frame 2 and is fixedly connected with a pressing plate 51. Automatic slide rail groups are symmetrically distributed on the inner surface of the frame 2. The automatic slide rail group consists of two automatic slide rails 52. An infrared radiation heating frame 53 is fixedly installed on the surface of the slider of the automatic slide rail 52. The telescopic movement of the piston rod of the hydraulic cylinder 5 drives the pressing plate 51 connected thereto to move up and down. The foam is arranged at the bottom of the pressing plate 51. As the pressing plate 51 moves down, it drives the foam to contact the automotive parts, and the movement of the slider on the automatic slide rail 52 drives the infrared radiation heating frame 53 to move to the middle of the frame 2 to heat and melt the hot melt adhesive on the automotive parts, so that it is convenient for the foam to adhere to the automotive parts.

[0060] Among them, in order to make the foam fit the outer surface of the automotive parts completely, the set edge wrapping mechanism includes clamping plates 7 symmetrically distributed on the inner wall of the placement groove 3. Two through holes 701 are formed through the surface of the clamping plate 7. One end surface of the electric telescopic rod 612 is slidably connected with the inner wall of the through hole 701. The movement of the clamping plate 7 drives the foam to wrap the edge of the automotive parts.

[0061] In order to connect the electric telescopic rod 612 with the clamping plate 7, support ring blocks 702 are fixedly installed on the inner walls of the four through holes 701. The inner surface of the support ring block 702 is provided with limiting grooves 703 distributed in a circular array. A clamping block 704 is slidably clamped on the inner wall of the limiting groove 703. A limiting rod 705 is fixedly connected to one side surface of the clamping block 704. One side surface of the four support ring blocks 702 is installed with a driven gear 706 through a bearing. The surface of the driven gear 706 is provided with inclined grooves 707 distributed in a circular array. The inclined groove 707 communicates with the limiting groove 703. The surface of the limiting rod 705 is slidably clamped with the inner wall of the inclined groove 707. By rotating the driven gear 706, the limiting rod 705 is driven to move along the inner wall of the inclined groove 707. The movement of the limiting rod 705 drives the clamping block 704 to move along the inner wall of the limiting groove 703, so as to facilitate the clamping block 704 to clamp the electric telescopic rod 612, and the extension of the electric telescopic rod 612 drives the clamping plate 7 to move.

[0062] In order to drive the driven gear 706 to rotate, servo motors 708 are fixedly installed on the opposite side surfaces of the two clamping plates 7. One end of the output shaft of the servo motor 708 is fixedly sleeved with a driving gear 709. The axis of the driving gear 709 is installed on the inner wall of the clamping plate 7 through a bearing. The driving gear 709 meshes with one of the driven gears 706. A rack 710 is slidably connected to the inner wall of the clamping plate 7. The two driven gears 706 mesh with the rack 710. By rotating the output shaft of the servo motor 708, the driving gear 709 connected thereto is driven to rotate. The rotation of the driving gear 709 drives the driven gear 706 meshing therewith to rotate. The rotation of this driven gear 706 drives the rack 710 to move. The movement of the rack 710 drives the other driven gear 706 to rotate.

[0063] By setting the edge wrapping mechanism and the hot pressing mechanism, after the hot melt adhesive is heated and melted, the foam is adhered to the automotive parts, and the part of the foam that extends beyond the automotive parts can be attached to the automotive parts, so as to facilitate the one-time wrapping of the automotive parts and improve the production efficiency.

[0064] Working principle: When in use, place the automotive parts into the placement groove 3, and then start the pushing cylinder 601. The extension of the piston rod of the pushing cylinder 601 drives the T-shaped plate 602 connected to it to move upward. The upward movement of the T-shaped plate 602 drives the positioning plate 603 to move upward along the inner wall of the through groove 605. The upward movement of the positioning plate 603 drives the positioning column 604 to move upward. Then start the stepping motor 606. The rotation of the output shaft of the stepping motor 606 drives the rotating shaft 607 connected to it to rotate. The rotation of the rotating shaft 607 drives the cam 608 to rotate, causing the cam 608 to drive the clamping column 610 to move downward along the inner wall of the sliding groove 609 and separate from the clamping groove 611, so that the connection between the T-shaped plate 602 and the positioning plate 603 is disconnected. Then start the electric telescopic rod 612, so that the telescopic rod of the electric telescopic rod 612 is inserted into the slot 614, facilitating the adsorption of the first magnet 613 and the second magnet 615. Then, as the electric telescopic rod 612 extends, it drives the positioning plate 603 to move, so that the positioning column 604 contacts the automotive parts, thereby positioning the automotive parts;

[0065] Then, use the pneumatic gripper 49 to pick up the hot melt adhesive. Start the movement of the slider on the self-driven slide rail 4 to drive the installation housing 41 connected to it to move. When it moves to the appropriate position, start the rotating motor 42. The rotation of the output shaft of the rotating motor 42 drives the turntable 43 connected to it to rotate, so that the pneumatic gripper 49 is aligned with the placement groove 3, and start the drive motor 45. The rotation of the output shaft of the drive motor 45 drives the screw rod 46 connected to it to rotate. The rotation of the screw rod 46 drives the moving sleeve rod 47 to move along the inner wall of the support sleeve rod 44, so that the starting gripper is located above the placement groove 3. Then start the electric lifting rod 48, so that the pneumatic gripper 49 approaches the automotive parts in the placement groove 3, facilitating the placement of the hot melt adhesive on the pneumatic gripper 49 onto the automotive parts;

[0066] Then, drive the positioning plate 603 to reset by the electric telescopic rod 612. Then start the stepping motor 606, so that the cam 608 drives the clamping column 610 to move upward along the inner wall of the sliding groove 609 and engage with the clamping groove 611. Then, the electric telescopic rod 612 contracts to cause the first magnet 613 and the second magnet 615 to be desorbed. Then, the contraction of the piston rod of the pushing cylinder 601 drives the positioning plate 603 and the positioning column 604 to move downward along the inner wall of the through groove 605 and be stored in the operating table 1;

[0067] Then start the automatic slide rail 52. The movement of the slider on the automatic slide rail 52 drives the infrared radiation heating frame 53 to move to the middle of the frame 2 to heat and melt the hot melt adhesive on the automotive parts. Then start the hydraulic cylinder 5. The extension of the piston rod of the hydraulic cylinder 5 drives the pressing plate 51 connected to it to move downward. As the pressing plate 51 moves downward, it drives the foam to contact the automotive parts;

[0068] Meanwhile, the servo motor 708 is started. The rotation of the output shaft of the servo motor 708 drives the rotation of the driving gear 709 connected thereto. The rotation of the driving gear 709 drives the rotation of the driven gear 706 meshing therewith. The rotation of the driven gear 706 drives the movement of the rack 710. The movement of the rack 710 drives the rotation of another driven gear 706. The rotation of the driven gear 706 drives the limiting rod 705 to move along the inner wall of the inclined groove 707. The movement of the limiting rod 705 drives the clamping block 704 to move along the inner wall of the limiting groove 703, thereby facilitating the clamping of the electric telescopic rod 612 by the clamping block 704. The extension of the electric telescopic rod 612 drives the movement of the clamping plate 7. The relative movement of the two clamping plates 7 drives the edge of the foam-coated automotive part.

[0069] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
