Description

Technical Field

[0001] This utility model belongs to the technical field of automotive interior inlay injection molding device, specifically relating to an inlay injection molding device for a U-shaped fabric hinge flange slot in a dashboard. Background Technology

[0002] Currently, a distributed approach is often used in the production of U-shaped fabric hinges for dashboards. Specifically, this involves deploying robots and a loading platform for fabric hinges and threaded bushings on the non-operating side of the injection molding machine. During operation, the robot picks up the pre-bent fabric hinges and threaded bushings and precisely inserts them into the injection mold. After injection molding, a robotic arm on the injection molding machine removes the product from the machine and places it on a conveyor belt.

[0003] However, this process has the following obvious shortcomings:

[0004] 1. Because additional robots and loading platforms need to be installed on the non-operational side, the equipment's footprint is significantly increased;

[0005] 2. The interaction between the robot and the robotic arm increases the cycle time of injection molding production.

[0006] 3. The system includes multiple components such as robots, feeding platforms, and injection molding machine robotic arms, which significantly increases the difficulty of system debugging and extends the debugging cycle accordingly.

[0007] Actual measurements show that the traditional distributed solution has an average cycle time of 95 seconds and requires 8 square meters of equipment space; while this utility model can shorten the cycle time to 88 seconds and reduce the footprint by 60% through integrated design.

[0027] Example 1

[0028] An inlay injection molding device for a U-shaped fabric hinge flange slot in a dashboard, such as Figure 1-2 As shown, it includes a fabric hinge gripping mechanism and a threaded sleeve gripping mechanism; the threaded sleeve gripping mechanism is arranged above the fabric hinge gripping mechanism, which can effectively avoid positional interference between the two structures; the threaded sleeve gripping mechanism includes a gripper mounting plate 3, a bushing gripping cylinder 4, and a metal threaded bushing pickup assembly 6 (the metal threaded bushing pickup assembly is described in the patent description with patent number ZL 201921637761.2), wherein the bushing gripping cylinder 4 is fixed at both the front and rear ends below the gripper mounting plate 3, and the metal threaded bushing pickup assembly 6 is connected to the telescopic end of the corresponding bushing gripping cylinder 4 through the threaded bushing pickup assembly mounting plate 19, and can move up and down under the drive of the bushing gripping cylinder 4;

[0029] The fabric hinge gripping mechanism includes a cylinder 5, a pull plate cylinder 7, a fabric hinge pre-compression cylinder 8, a spring plunger 9, a front fabric hinge clamping plate 10, a rear fabric hinge clamping plate 11, and a needle suction cup 12. The cylinder 5 is fixed below the rear end of the gripper mounting plate 3, and a pull plate cylinder mounting plate 14 is fixed to its telescopic end. Pull plate cylinders 7 are fixed at the four corners above the pull plate cylinder mounting plate 14, and needle suction cups 12 are fixed at the four corners at the bottom. The rear end of the front fabric hinge clamping plate 10 is connected by screws to the telescopic ends of the two pull plate cylinders 7 located at the front end. The telescopic ends of cylinders 7 all face the front end. The front end of the rear fabric hinge clamping plate 11 is connected to the telescopic ends of the two pull plate cylinders 7 located at the rear end by screws (the telescopic ends of these two pull plate cylinders 7 all face the rear end). A spring plunger mounting plate 15 is provided below the pull plate cylinder mounting plate 14, and spring plungers 9 are provided at the four corners of the spring plunger mounting plate 15. The fabric hinge pre-compression cylinder 8 is fixed to the pull plate cylinder mounting plate 14 at the rear end of cylinder 5 by the pre-compression cylinder mounting bracket 20, and its telescopic end passes through the pull plate cylinder mounting plate 14 and is connected to the spring plunger mounting plate 15.

[0030] The spring plunger mounting plate 15 has threaded holes at its four corners. The spring plunger 9 is connected to the corresponding threaded hole through external thread engagement and is locked by a nut.

[0031] The spring plunger 9 includes a plunger body, an internal spring, and a telescopic ejector pin. When an external force is received, the ejector pin compresses the spring and retracts; when the external force disappears, the spring returns to its original position, and the ejector pin pops out.

[0032] It also includes a fabric hinge detection sensor 13, which is mounted on the bottom of the pull plate cylinder mounting plate 14 via a photoelectric switch bracket 21, and its sensing end passes through the spring plunger mounting plate 15.

[0033] It also includes a handle 16, which is fixed to the rear end of the gripper mounting plate 3.

[0034] It also includes a reversible pressure reducing valve 17, whose inlet end is connected to the air passage interface of the exchange fixture 1 via an air pipe, and whose outlet end is connected to the inlet end of the cylinder 5 via an air pipe. By adjusting its pressure, the thrust of the cylinder 5 can be effectively controlled, effectively reducing the force between the gripper and the mold. At the same time, it can also reduce the pressure between the gripper and the inlay platform when the needle-punched suction cup grips the fabric hinge, thereby effectively protecting the gripper.

[0035] It also includes a junction box 22, which has multiple sets of electrical terminals installed inside. On the one hand, it is used to gather the signals of the cylinder magnetic switch and photoelectric switch into the box. On the other hand, it is connected to the electrical interface of the robot arm exchange fixture 1 through two sets of 9-pin serial cables.

[0036] The threaded sleeve gripping mechanism also includes a robotic arm exchange fixture 1, which is fixed above the front end of the gripper mounting plate 3 via an exchange fixture connecting plate 2, and is used to install the magnetic switches of each cylinder and the photoelectric switches of the sensors.

[0037] The robotic arm exchange fixture 1 is equipped with standardized mechanical and electrical interfaces, allowing for the integrated pneumatic and electrical signals of the gripper. This eliminates the need for manual insertion and removal of air hoses, effectively preventing errors and enabling lightning-fast gripper switching, thus injecting convenient momentum into efficient operations.

[0038] The gripper mounting plate 3 is an integral V-shaped plate, wherein the robotic arm exchange clamp 1 is fixed to the top side plate of the V-shaped plate through the exchange clamp connecting plate 2, the bushing gripping cylinder 4 at the front end of the gripper mounting plate 3 is directly fixed to the front end of the bottom side plate of the V-shaped plate, the bushing gripping cylinder 4 at the rear end of the gripper mounting plate 3 is fixed to the rear end of the bottom side plate of the V-shaped plate through the I-beam frame, and the cylinder 5 is fixed on the gripper mounting plate 3 below the I-beam frame.

[0039] The process of using this utility model:

[0040] Place the device above the feeding platform for the fabric hinge and threaded bushing, activate the bushing gripping cylinder 4 at one end, causing it to move the corresponding metal threaded bushing picking component 6 downward to pick up the threaded bushing. Then activate the bushing gripping cylinder 4 at the other end, causing it to move the corresponding metal threaded bushing picking component 6 downward to pick up the threaded bushing. After picking up the bushing, the bushing gripping cylinder 4 moves the metal threaded bushing picking component 6 containing the threaded bushing upward to return to its original position.

[0041] Then, the front-end pull-plate cylinder 7 drives the front fabric hinge clamping plate 10 to move outward, and the rear-end pull-plate cylinder 7 drives the rear fabric hinge clamping plate 11 to move outward, so that the space between the front and rear fabric hinge clamping plates 10 and 11 can accommodate the fabric hinge 18. The cylinder 5 is then activated, causing the pull-plate cylinder mounting plate 14 to move downward until the needle suction cup 12 reaches the desired position and picks up the fabric hinge 18. After the fabric hinge is picked up, the cylinder 5 retracts back to its original position.

[0042] Finally, the metal threaded bushing and the fabric hinge are placed separately. The device is placed above the injection mold. The height of the pull plate cylinder mounting plate 14 is adjusted by the cylinder 5 so that the fabric hinge 18 is above the installation position. Then, the front pull plate cylinder 7 drives the front fabric hinge clamping plate 10 to move inward, and the rear pull plate cylinder 7 drives the rear fabric hinge clamping plate 11 to move inward. The lower parts of the front fabric hinge clamping plate 10 and the rear fabric hinge clamping plate 11 respectively squeeze the flanges on both sides of the fabric hinge 18, so that the bent fabric hinge 18 is effectively fitted with the side of the mold. Then, the cylinder 5 extends and drives the pull plate cylinder mounting plate 14 and the various components installed on it to move downward, so that the flanges on both sides of the fabric hinge 18 are inserted into the slots of the U-shaped fabric hinge flanges on the mold, ensuring the reliability of the fabric hinge inlay.

[0043] After the fabric hinge 18 is in place, the needle suction cup 12 cancels the suction force on the fabric hinge 18, and at the same time the fabric hinge pre-compression cylinder 8 extends, pushing the spring plunger mounting plate 15 and the spring plunger 9 to move downward, thereby pre-compressing the fabric hinge 18 and preventing the needle suction cup 12 from pulling the fabric hinge 18 placed in the mold out, so as to ensure the consistency of the fabric hinge embedding position.

[0044] This action not only ensures that the fabric hinge fits tightly against the mold surface, but also cleverly avoids the material carrying problem that may occur with the needle suction cup 12—preventing the fabric hinge from being accidentally pulled away from the mold, curbing the generation of defective products from the source, and building a solid defense line for production quality.

[0045] Finally, the bushing gripping cylinder 4 drives the corresponding metal threaded bushing pickup assembly 6 to move downward, placing the threaded bushing in the corresponding position.

[0046] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the scope of protection of the present invention is not limited to the specific details in the above embodiments. Within the scope of the technical concept of the present invention, any equivalent substitutions or modifications made by those skilled in the art based on the technical solution and the inventive concept of the present invention within the scope of the technical concept disclosed in the present invention shall all fall within the scope of protection of the present invention.

[0047] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0048] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
