The first upper clamping block 3211 is rotatably connected to the first lower clamping block 3212. The first clamping driver 3213 can drive the first upper clamping block 3211 to flip vertically, causing the first upper clamping block 3211 to press the diaphragm for the automobile instrument panel against the first lower clamping block 3212. In this embodiment, the first clamping driver 3213 is a cylinder.

[0051] The second clamping assembly 322 includes a second upper clamping block 3221 and a second clamping driver 3223. The second clamping driver 3223 can drive the second upper clamping block 3221 to rotate horizontally above the diaphragm for the automobile instrument panel and then vertically descend to press the diaphragm for the automobile instrument panel against the horizontal support platform 12. In this embodiment, the second clamping driver 3223 is a cylinder.

[0052] In this embodiment, there are three first clamping assemblies 321, arranged side by side on one side of the horizontal support platform 12; there are two second clamping assemblies 322, one on each side of the three first clamping assemblies 321.

The first horizontal guide rail 412 is disposed on the bracket 11 along a first horizontal direction, and the first slider 413 is movably disposed on the first horizontal guide rail 412. The first horizontal drive motor 411 is connected to the first slider 413 and is capable of driving the first slider 413 to slide along the first horizontal guide rail 412.

[0056] In this embodiment, in order to improve stability during movement, the number of the first horizontal guide rails 412 and the first slider 413 are both set to two, the two first horizontal guide rails 412 are parallel to each other, and the two first sliders 413 are respectively set on the two first horizontal guide rails 412.

[0057] The first horizontal moving unit 41 also includes a transmission gear and a rack 414 that cooperates with the transmission gear. The rack 414 is disposed on one side of one of the first horizontal guide rails 412 and is parallel to the first horizontal guide rail 412. The first horizontal drive motor 411 is mounted on the first slider 413 corresponding to the first horizontal guide rail 412. The gear is disposed at the output end of the first horizontal drive motor 411 and meshes with the rack 414. During operation, the gear rotates under the drive of the first horizontal drive motor 411, meshing with the rack 414 while moving along the extension direction of the rack, thereby driving the first slider 413 to slide along the corresponding first horizontal guide rail 412.

[0058] The second horizontal movement unit 42 includes a second horizontal drive motor 421, a second horizontal guide rail 422, and a second slider 423 adapted for the second horizontal guide rail 422.

Before processing begins, the corresponding upper die 1021 and lower die 1022 must be mounted on the die support 1023. During operation, a semi-finished decorative part is placed on the lower die 1022, and the upper die 1021 descends to punch the semi-finished decorative part into a finished decorative part. The excess material punched out is waste material.

[0065] Figure 12 1 is a schematic structural diagram of a transfer device for punching decorative parts of an automobile instrument panel according to an embodiment of the present invention.

[0066] The transfer device 103 for punching automobile instrument panel decorative parts can transfer semi-finished decorative parts, finished decorative parts and waste materials. Figure 12 As shown, the transfer device 103 for punching automobile instrument panel decorative parts includes a base 60 , a mechanical arm 70 and a piece-taking mechanism 80 .

[0067] The base 60 is located on the ground next to the punching station and can stably support the robotic arm 70. In this embodiment, the base 60 includes a rectangular frame 61 connected by multiple rods and four support legs 62 located at the four corners of the bottom of the frame 61. The four support legs 62 are fixed to the ground with bolts, making the base 60 highly stable and not prone to shaking.

[0068] A robotic arm 70 is mounted on top of the base 60 and is capable of driving the removal mechanism 80. In this embodiment, the robotic arm 70 is a six-axis ABB IRB2600 robot with a capacity of 20 kg / 1.65 m. A quick-change plate 71 is mounted at the end of the robotic arm 70, which is connected to the removal mechanism 80. The specific structures of the robotic arm 70 and the quick-change plate 71 are conventional and will not be further described here.

[0069] Figure 13 It is a structural diagram of the pickup mechanism in an embodiment of the present invention.

[0070] The pick-up mechanism 80 is adapted to the semi-finished decorative part to be punched and is detachably connected to the robot arm 70 via the quick-change plate 71. Figure 13 As shown, the picking mechanism 80 includes a clamping unit 81 , a suction unit 82 and a mounting frame 83 .

[0071] The mounting bracket 83 is removably mounted on the robotic arm 70 via the quick-change plate 71. In this embodiment, the mounting bracket 83 comprises a mounting rod 831 and a connector 832. The mounting rod 831 is formed of profiled steel, and its length is adapted to the dimensions of the semi-finished decorative part to be punched. The connector 832 is positioned in the middle of the mounting rod 831 and is connected to the quick-change plate 71. Two symmetrical hanging holes 8321 are provided on the connector 832 to facilitate hanging and storing the removal mechanism 80 after it has been removed from the robotic arm 70.

[0072] Figure 14 This is a schematic diagram of the structure of the film cutting device for automobile instrument panel in an embodiment of the present invention. Figure 2 .

[0073] like Figure 14 As shown, the support portion 10 further includes at least one pickup mechanism storage bracket 13 disposed on one side of the bracket 11. In this embodiment, the number of the pickup mechanism storage brackets 13 is set to four, and all are located on the same side of the bracket 11.

[0074] Figure 15 It is a structural schematic diagram of the storage bracket of the pickup mechanism in an embodiment of the present invention.

[0075] like Figure 15 As shown, the pickup mechanism storage bracket 13 has a hook 131 that is compatible with the hanging hole 8321, which can hang the pickup mechanism 80 removed from the transfer device 103 for punching automobile dashboard decorative parts, so as to facilitate installation and use next time.

[0076] The suction unit 82 is disposed on the mounting frame 83 and can suck the semi-finished decorative part to be punched or the finished decorative part obtained by punching. In this embodiment, the suction unit 82 includes a plurality of vacuum suction cups 821 that can be connected to a vacuum generator and a plurality of suction cup brackets 822.

[0077] The suction cup brackets 822 are capable of mounting the vacuum cups 821 on the mounting rod 831. The number of suction cup brackets 822 is equal to the number of vacuum cups 821, and they are connected one-to-one. The multiple vacuum cups 821 are evenly spaced, and their locations correspond to the decorative parts on the semi-finished decorative part. Therefore, the suction unit 82 can absorb both semi-finished decorative parts and finished decorative parts obtained after punching. In this embodiment, there are four vacuum cups 821, which are evenly spaced along the length of the mounting rod 831.

[0078] The gripping unit 81, mounted on the mounting frame 83, is capable of gripping the edge scraps punched from the semi-finished decorative part. It comprises at least one gripping assembly 811 and a gripping driver. In this embodiment, two gripping assemblies 811 are provided. These two gripping assemblies 811 are symmetrically located at either end of the mounting rod 831. The distance between the two gripping assemblies 811 corresponds to the length of the semi-finished decorative part, enabling stable gripping of the edge scraps punched from the semi-finished decorative part from both ends.

[0079] In the punching device 102 for automotive instrument panel trim, the lower die 1022 that supports the semi-finished trim has a boss that matches the shape of the trim. During punching, the upper die 1021 separates the trim portion in the center of the semi-finished trim from the outer edge along the contour of the boss. The punched edge may become lodged against the side of the boss.

[0080] In this embodiment, the gripping unit 81 also includes an equal number of lifting cylinders 812 as the gripping assemblies 811. The two lifting cylinders 812 are positioned at either end of the mounting rod 831, and the two gripping assemblies 811 are connected to the output ends of the two lifting cylinders 812, respectively. The lifting cylinders 812 drive the gripping assemblies 811 up and down, gripping the edge of the waste material after it is punched and lifting it, freeing it from the boss on the die. This facilitates smoother transfer of the waste material from the punching die by the transfer device.

[0081] In actual application, the gripping unit 81 may not be provided with a lifting cylinder. Instead, the first clamping block of the gripping assembly 811 may be directly fixed to the mounting rod 831, thereby still realizing the gripping function of the gripping assembly 811. After the gripping assembly 811 grips the edge portion of the waste material that has been punched out, the robotic arm 70 drives the entire gripping unit 81 to rise in a direction perpendicular to the height of the boss of the lower die 1022, thus smoothly removing the waste material from the lower die 1022.

[0082] Figure 16 yes Figure 13 Magnified view of the structure within the middle circle D.

[0083] like Figure 16As shown, in this embodiment, each clamping assembly 811 includes a first clamping block 8111 and a second clamping block 8112. The first clamping block 8111 is arranged on the output end of the lifting cylinder 812, and one side of the second clamping block 8112 is rotatably connected to the first clamping block 8111, and the second clamping block 8112 forms a clamping claw-like structure that can be opened and closed on the first clamping block 8111. The clamping drive is connected to the second clamping block 8112, and the clamping drive is configured to drive the second clamping block 8112 to rotate and press toward the first clamping block 8111, so that the first clamping block 8111 and the second clamping block 8112 clamp the waste from both sides respectively. The clamping surfaces of the first clamping block 8111 and the second clamping block 8112 that contact the waste are both provided with an anti-slip layer, which can increase the friction during clamping, making the clamping more stable and accurate.

[0084] In this embodiment, to simplify the structure and reduce costs, a vacuum generator connected to the vacuum suction cup 821 serves as the clamping drive. The clamping assembly 811 and the vacuum suction cup 821 share the vacuum generator, and the gas output by the vacuum generator drives the second clamping block 8112 to rotate and clamp. In actual applications, a separate clamping cylinder can also be provided as the clamping drive.

The pickup mechanism is detachably connected to the robotic arm via a quick-change plate, making it easy to replace the corresponding pickup mechanism according to the type of decorative part being punched during actual production and processing. The same robotic arm can be used for transfer work during the punching process of decorative semi-finished products of different specifications and models. Only the pickup mechanism that is compatible with the semi-finished decorative part needs to be replaced, eliminating the need for a complete set of transfer devices for punching automotive dashboard decorative parts, which helps reduce the manufacturer's equipment costs.

[0095] Specifically, the retrieval mechanism includes a clamping unit, a suction unit, and a mounting frame. The clamping unit is capable of clamping waste materials, and the suction unit is capable of sucking up semi-finished decorative parts or finished decorative parts. The suction unit includes multiple vacuum suction cups that can be connected to a vacuum generator and multiple suction cup brackets. The number of suction cup brackets is equal to the number of vacuum suction cups, and they are connected one-to-one. The multiple vacuum suction cups are evenly arranged along the length of the mounting rod, and the positions of the vacuum suction cups correspond to the decorative parts of the semi-finished decorative parts, which has a high degree of adaptability. The clamping unit includes two clamping assemblies, which are located at both ends of the mounting rod and are symmetrical to each other. The distance between the two clamping assemblies corresponds to the length of the semi-finished decorative parts, and can stably clamp the edge waste parts punched off the semi-finished decorative parts from both ends. The retrieval mechanism adopts different retrieval methods for finished decorative parts and waste materials in a targeted manner, with high adaptability and greater stability, which can reduce the scrap rate and improve the quality and precision of the finished products.
