Description

Technical Field

[0001] The invention relates to the technical field of plastic part punching detection, in particular to an automatic punching detection device for special-shaped porous plastic parts. Background Art

[0002] In the field of plastic parts processing, special-shaped porous plastic parts, such as automotive interior parts and electronic equipment housings, are mostly produced by injection molding. After molding, they need to be punched by punching equipment. However, the punching quality directly affects the assembly accuracy and performance of the product. Therefore, inspection equipment is needed to detect the hole position and appearance. In the existing technology, the punching inspection of plastic parts has the following deficiencies: Low degree of automation: Traditionally, when punching and testing plastic parts, most of the time, the injection-molded plastic parts are taken out manually and transported to the next process via a conveyor belt. The staff then places the plastic parts on the punching equipment for punching and testing. Such a process consumes a lot of time and increases labor. At the same time, the plastic parts need to be positioned when they are placed, and improper operation can easily affect the quality of production.

[0003] Insufficient adaptability: For plastic parts with special shapes or multiple holes, existing automated inspection equipment usually adopts fixed-station inspection, which cannot flexibly adapt to products of different specifications and requires frequent replacement of tooling fixtures, which is time-consuming and labor-intensive.

[0004] Limited detection accuracy: Although some equipment uses photo detection, the light source angle and camera height are fixed, making it difficult to clearly capture the punching details of complex structures. This is especially true for special hole positions such as deep holes and inclined holes, which are prone to missed detection or misjudgment.

[0005] Extensive waste handling: There is a lack of automated sorting mechanism for defective and qualified products. Manual sorting can easily lead to interruptions in the production process, and the accumulation of defective products may affect subsequent processes.

[0006] Furthermore, the trend toward lighter and more complex plastic parts is placing higher demands on the efficiency, accuracy, and intelligence of punching inspection. Existing technologies lack an integrated automated device for punching, inspection, and sorting, making efficient control of the entire process difficult. Therefore, there is an urgent need to design an automated inspection device suitable for irregular-shaped, porous plastic parts to address these challenges. Summary of the Invention

[0028] Specifically, such as Figure 1 and Figure 2 As shown, the punching mechanism 7 includes a first mounting frame 701, and a first mounting frame 701 is installed on one side of the blow molding machine 1. Two punching assemblies 703 are installed on the first mounting frame 701. Six first anti-shape blocks 702 are respectively provided on the outside of the two punching assemblies 703. The bottom of the first anti-shape block 702 is connected to the top of the first mounting frame 701, and two diagonally distributed first anti-shape blocks 702 are installed on the outside with press-fitting cylinders 704. The installation of multiple first anti-shape blocks 702 is conducive to the simultaneous placement and stability of two plastic parts.

After the inspection is completed, the product is clamped by the robotic arm 602 and transferred to the conveyor belt 604 for export. At the same time, the defective products are clamped to the placement table 501 for easy recycling.

[0030] Specifically, such as Figure 8 and Figure 9As shown, a connecting plate 809 is slidably connected to the two support plates 806, and the camera 805 is detachably connected to the connecting plate 809. One side of the two support plates 806 is connected to an electric telescopic rod 810 through a fixing seat 811.

[0033] Specifically, such as Figure 4 、 Figure 5 and Figure 6As shown, an adjustment mechanism 9 is installed on the first mounting frame 701, and the adjustment mechanism 9 includes a slot 907. Two parallel slots 907 are provided at one end of the top of the first mounting frame 701. Slide blocks 901 are slidably connected inside the two slots 907. The bottoms of the two first anti-shape blocks 702 are fixedly connected to the tops of the two slide blocks 901. The first anti-shape blocks 702 are slidably connected to the top of the first mounting frame 701 through the slide blocks 901 and the slots 907. Screws 902 are threadedly connected inside the two first anti-shape blocks 702. The bottoms of the screws 902 pass through the sliders. 901 interferes with the inside of the card slot 907, and the top of the screw rod 902 extends to the outside of the top of the first anti-shape block 702. The opening of the two card slots 907 facilitates the installation of the slider 901. Through the connection between the first anti-shape block 702 and the slider 901, the first anti-shape block 702 can be slidably adjusted on the first mounting frame 701, which is convenient for placing plastic parts of different sizes stably. Through the rotation of the bolt 908, the limit control between the slider 901 and the card slot 907 is achieved, so that the first anti-shape block 702 can be stably supported.

[0034] Specifically, such as Figure 4 、 Figure 5 and Figure 6 As shown, the slot 907 and the slider 901 are both "convex" shaped structures, the bottom of the screw 902 is rotatably connected to a pressure plate 904, and the top of the screw 902 is installed with a turntable 903. The slot 907 is slidably connected to two dust covers 906, one end of the two dust covers 906 is connected to the inner wall of the slot 907, and the other end of the two dust covers 906 is connected to the outer side of the first anti-shape block 702, which is beneficial for the slider 901 to slide smoothly inside the slot 907 without slipping. The installation of the dust cover 906 is beneficial to shielding and protecting the slot 907, preventing debris from entering the slot 907 and affecting the sliding of the slider 901. The installation of the pressure plate 904 is beneficial to the close contact between the bottom of the bolt 908 and the bottom of the slot 907, and reducing wear.

[0035] Specifically, such as Figure 6 As shown, the inner sides of one ends of the two slots 907 are respectively engaged with the limiting blocks 905, and the limiting blocks 905 are threadedly connected with bolts 908. The bottom of the bolts 908 extend to the outside of the bottom of the limiting block 905 and interfere with the slots 907. Through the installation of the limiting blocks 905, it is beneficial to shield and protect one end of the slots 907 to prevent the slider 901 from slipping. By tightening the bolts 908, the limiting blocks 905 can be disassembled and assembled, which is beneficial to the replacement of the first anti-shape blocks 702 of different heights.

[0036] Specifically, such as Figure 1As shown, a piece-picking fixture 603 is installed on the robotic arm 602, a slide 601 is installed at the bottom of the robotic arm 602, and the bottom of the robotic arm 602 is slidably connected to the slide 601. A control cabinet 3 is installed on one side of the robotic arm 602, and a conveyor belt 604 and a plasma vacuum cleaner 4 are installed on one side of the first mounting frame 701. A guardrail 2 is provided on the outside of the blow molding machine 1, and the first mounting frame 701, the second mounting frame 801, the robotic arm 602 and the control cabinet 3 are all located on the inside of the guardrail 2.

The installation of the control cabinet 3 facilitates circuit control. The installation of the conveyor belt 604 facilitates the conveyor belt 604 of the inspected products. The installation of the guardrail 2 facilitates shielding and protection.

[0037] Specifically, such as Figure 1 As shown, the recycling mechanism 5 includes a placement table 501, and the placement table 501 is installed on one side of the conveyor belt 604. A placement groove 502 is provided on the top of the placement table 501. The placement table 501 is located on the inner side of the guardrail 2. The installation of the placement table 501 is conducive to the placement of defective products. The opening of the placement groove 502 makes it difficult for the product to fall after being placed, thereby playing a shielding role.

[0038] When the present invention is in use, the robot arm 602, the first mounting frame 701, and the second mounting frame 801 are first installed on one side of the injection molding machine 1, and a certain distance is reserved between the devices, while ensuring that they are within the grasping range of the robot arm 602. Then, the conveyor belt 604, the placement table 501, and the plasma vacuum cleaner 4 are installed on one side of the first mounting frame 701 and the second mounting frame 801, and the circuits of multiple devices can be connected through the control cabinet 3 to realize intelligent control. Finally, a protective fence 2 is installed on the periphery of the injection molding machine 1 to realize safety protection of multiple devices. After the injection molding machine 1 forms the plastic parts, the protective door is opened. After the robot arm 602 senses the signal through the optical sensor, the control cabinet 3 controls the robot arm 602 to work, and the robot arm 602 takes the parts and processes them. The tool 603 transfers the plastic parts to the first mounting frame 701. The installation of multiple first anti-shape blocks 702 facilitates the simultaneous placement and stabilization of two plastic parts. After the optical sensor detects the placement signal, the edges of the two plastic parts are clamped and fixed through the cooperation of multiple press-fitting cylinders 704. The opening of two card slots 907 facilitates the installation of the slider 901. The connection between the first anti-shape block 702 and the slider 901 enables the first anti-shape block 702 to slide and adjust its position on the first mounting frame 701, which is convenient for the stable placement of plastic parts of different sizes. The rotation of the bolt 908 realizes the limit control between the slider 901 and the card slot 907, so that the first anti-shape block 702 can be stably supported, which is conducive to the slider 901 being positioned in the card slot 9 07 slides smoothly inside and will not slip off. The installation of dust cover 906 is conducive to shielding and protecting the card slot 907, preventing debris from entering the card slot 907 and affecting the sliding of the slider 901. The installation of pressure plate 904 is conducive to the close contact between the bottom of bolt 908 and the bottom of the card slot 907, and reduces wear. The installation of limit block 905 is conducive to shielding and protecting one end of the card slot 907, preventing the slider 901 from slipping. The limit block 905 can be disassembled and assembled by tightening the bolt 908, which is conducive to replacing the first anti-shape block 702 of different heights. After the plastic part is clamped stably, the two punching assemblies 703 work to punch the plastic part, which is convenient for subsequent assembly and use. After punching is completed, the pressing cylinder 704 is reset and the robot arm 602 For picking up and unloading plastic parts, the robot arm 1 transfers the punched plastic parts to the plasma vacuum cleaner 4 to remove debris, and then transfers them to the second mounting rack 801. Through the installation of multiple second anti-shape blocks 802, the plastic parts after punching are placed stably. After the plastic parts are placed, the optical sensor detects the signal, and the control cabinet 3 continues to control the work of multiple clamping cylinders 803 to achieve stable clamping of the plastic parts. Through the cooperation of the lighting lamp 804, it is convenient for the camera 805 to take pictures of the plastic parts for inspection, thereby ensuring the quality of the product. After the inspection is completed, the product is clamped by the robot arm 602 and transferred to the conveyor belt 604 for export. At the same time, the defective products are clamped and placed on the placement table 501 for easy recycling. Through the installation of the connecting plate 809,The camera 805 is conveniently connected to the support plate 806. The installation of the fixing seat 811 facilitates the connection of the electric telescopic rod 810. The electric telescopic rod 810 is controlled according to the height of the product, and the electric telescopic rod 810 controls the connecting plate 809 to slide on the support plate 806, which facilitates the height adjustment of the camera 805 and achieves better photo detection. The installation of the connecting spring 812 facilitates the pulling of the connecting plate 809, so that the connecting plate 809 and the support plate 806 are stable and will not loosen when sliding. The installation of two sets of connecting blocks 807 facilitates the connection of the two lighting lamps 804. The control of the drive motor 808 enables the lighting lamps 804 to rotate and adjust the angle on the connecting blocks 807, making it convenient to adjust the light angle according to the shape of the product, facilitating clear photo detection by the camera 805. The installation of the placement table 501 facilitates the placement of defective products. The opening of the placement slot 502 prevents the product from falling after placement, thus playing a shielding role.
