Description

Technical Field

[0001] This utility model relates to the field of injection molding, and in particular to a paint mist removal device for injection molded products. Background Technology

[0002] For injection-molded products such as bumpers, during the painting process on side A, the paint mist can adhere to side B. For some parts, side B requires piercing welding or structural adhesive bonding. Taking piercing welding as an example, the paint mist on side B significantly reduces weld strength, failing to meet quality standards. To solve this problem, a common practice is to cover the welding area on side B with tape before painting, and then remove the tape before welding. This method requires additional manual labor for applying and removing the tape during the injection molding process, typically adding one to two people per process, and sometimes even four people for some parts. Furthermore, the tape itself represents a cost.

[0003] Therefore, how to remove paint mist adhering to injection molded products in a low-cost and efficient manner to ensure welding or bonding strength is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0007] The robotic arm is a six-axis robot located in the middle of the housing, the laser emitter is a laser marking machine, and the injection-molded product support assembly is located between the door assembly and the robotic arm.

[0008] There are two robotic arms, located in the middle of the box and spaced apart along the left and right sides of the box. There are two injection molding product support components, located on the front and rear sides of the robotic arms, respectively.

[0009] The top of the housing is equipped with an exhaust pipe and an axial flow fan, forming an exhaust assembly. The downstream end of the exhaust pipe is connected to the waste gas treatment system.

[0010] The injection molded product support assembly includes a skeleton and several support blocks assembled on the skeleton, the distribution of which is adapted to the support surface of the injection molded product.

[0011] Each support block is equipped with a through negative pressure port, which is connected to a negative pressure source.

[0012] The side walls and / or door assemblies of the enclosure are provided with observation windows.

[0013] The box is equipped with two shelves, located on the left and right sides of the robotic arm, respectively.

[0014] The above technical solution has the following beneficial effects: 1. A paint mist removal device for injection molded products includes a housing. At least one side wall of the housing is open and equipped with a door assembly that allows the opening to be opened or closed. The door assembly allows the housing to be closed or the side wall to be open. When the door assembly is open, injection molded products can be placed or removed into the housing through the opening. When the door assembly is closed, the housing is sealed, allowing for paint mist removal operations and preventing dust and volatile gases from polluting the working environment. The housing is equipped with an extraction assembly that extracts dust and volatile gases generated during the paint mist removal process for treatment. The housing contains an injection molded product support assembly and a robotic arm, wherein the injection molded product support assembly is used to position the injection molded product. The free end of the robotic arm is detachably equipped with a laser emitter and a high-pressure air nozzle. The high-pressure air nozzle is connected to a compressed air source. The robotic arm drives the laser emitter to emit a laser onto the positioned injection-molded product, ablates the paint mist, and removes the paint mist. The high-pressure air nozzle sprays high-pressure gas to blow away the removed paint mist and some of the dust generated during ablation from the injection-molded product, preventing smoke from obscuring the laser and reducing the ablation effect, and exposing clean welding or bonding surfaces to meet welding or bonding requirements. In addition, the sprayed high-pressure gas can also eliminate open flames and ensure product safety.

[0015] 2. The front and rear sides of the box are open, and door components are provided to open or close the openings respectively. The door components are roller shutter doors, and the robotic arm is a six-axis robot located in the middle of the box. The injection molded product support component is located between the door components and the robotic arm, which facilitates the placement and retrieval of injection molded products.

[0016] 3. The injection molding product support assembly includes a skeleton and several support blocks assembled on the skeleton. The distribution of the support blocks is adapted to the support surface of the injection molding product. The injection molding product is placed on the injection molding product support assembly and supported by multiple support blocks. Each support block is provided with a through negative pressure port connected to a negative pressure source. The injection molding product, such as an injection molding safety bar, has a certain degree of elasticity. The negative pressure adsorption of the injection molding product fixes its position, preventing it from warping and detaching from the focal area of ​​the laser emitter, thus ensuring the ablation effect of the laser emitter on the paint mist on the surface of the injection molding product.

The paint mist removal device for injection molded products includes a housing 1, at least one side wall of the housing 1 is open and provided with a door assembly 2 for opening or closing the opening, and the housing 1 is provided with an exhaust assembly 3. In this embodiment, both the front and rear sides of the housing 1 are open, and the door assembly 2 is provided to open or close the opening respectively. Specifically, the door assembly 2 is a roller shutter door, which can be installed using a conventional structure. An exhaust pipe is provided on the top of the housing 1, and an axial flow fan is provided to form the exhaust assembly 3. The downstream end of the exhaust pipe is connected to an exhaust gas treatment system. Typically, a damper is provided at the upstream end of the exhaust pipe. In order to facilitate observation of the working conditions inside the housing, observation windows 8 can also be provided on the left and right side walls and / or door assembly of the housing 1. The housing 1 contains an injection molding product support assembly 4 and a robotic arm 5. Specifically, the robotic arm 5 is a six-axis robot located in the middle of the housing 1, and there are two robotic arms 5, spaced apart along the left and right directions of the housing 1. The six-axis robot is purchased from YASKAWA, model YRC1000 GP25. Obviously, there are also two injection molding product support assemblies 4, located on the front and rear sides of the robotic arms 5 respectively. One robotic arm corresponds to one injection molding product support assembly, which improves the space utilization of the housing and the processing capacity of injection molding products. The injection molding product support assembly 4 includes a frame 41 and several support blocks 42 assembled on the frame 41. The distribution of the support blocks 42 is adapted to the support surface of the injection molding product. In order to ensure the positional accuracy of the injection molding product on the injection molding product support assembly, each support block 42 is provided with a through negative pressure port 43, which is connected to a negative pressure source. The free end of the robotic arm 5 is detachably equipped with a laser emitter 6 and a high-pressure air nozzle 7. Specifically, the laser emitter is a laser marking machine purchased from Wanxiao Technology, model WXQ-300M, and the high-pressure air nozzle is a duckbill nozzle.

[0021] Furthermore, two shelves 9 are provided inside the housing 1, located on the left and right sides of the robotic arm 5, respectively, for placing the equipment for disassembling the free end of the robotic arm.

[0022] The working principle of this utility model is as follows: Taking the processing of injection-molded bumpers as an example, the roller shutter door is opened, and the bumper is placed on the injection-molded product support component with the B-side (adhered to the paint mist) facing upwards. The negative pressure is turned on to adsorb and fix the bumper. The roller shutter door is closed, and the exhaust component is turned on to extract air. The six-axis robot drives the laser emitter to move, and the laser emitted by the laser emitter is focused on the position on the B-side of the bumper that needs to be bonded or welded, burning off the paint mist adhering to these positions. The high-pressure air nozzle blows the generated dust and exhaust gas away from the B-side and is discharged from the box by the exhaust component. After the processing is completed, the robotic arm is reset, the roller shutter door is opened, the negative pressure is stopped, and the processed bumper is taken out, ready for welding or bonding processes.
