[0002] With the booming development of pure electric vehicles, lightweighting is increasingly valued and favored by the industry due to limitations in battery structure and performance. Carbon fiber composite materials, with their lightweight and high strength properties, are finding wider application in electric vehicles. As an integral part of the vehicle's main structure, carbon fiber automotive parts have very high requirements for surface coating. Currently, the painting and sanding of carbon fiber trim is all done manually, which is time-consuming and has low paint removal efficiency. Utility Model Content

[0003] The purpose of this invention is to provide a composite material polishing device based on a robotic arm to solve the problems of long polishing time and low paint removal efficiency in traditional manual polishing.

[0004] To solve the above-mentioned technical problems, this utility model provides a composite material trim polishing device based on a robotic arm, including a frame and a worktable set on the frame; The workbench is divided into a sandpaper removal area, a sandpaper storage area, a sandpaper adhesion detection area, and a grating sensing area. A grinding robotic arm is also provided on one side of the frame, and a rotary grinding mechanism is installed at the end of the grinding robotic arm. After the old sandpaper on the rotary sanding mechanism is removed in the sandpaper removal area, a new sandpaper is picked up in the sandpaper storage area and, after being sensed by the grating sensing area, enters the sandpaper bonding detection area to detect the bonding stability.

[0005] Preferably, the area below the workbench is a sandpaper recycling area, and a sandpaper recycling box is placed in the sandpaper recycling area.

[0006] Preferably, the sandpaper removal area is provided with a sandpaper recycling trough that communicates with the sandpaper recycling area, and a sandpaper removal plate is fixedly installed on the sandpaper recycling trough; one side of the sandpaper removal plate is raised, and when the rotary grinding mechanism moves along the sandpaper removal plate under the drive of the grinding robot arm, the sandpaper at the end of the rotary grinding mechanism is separated and falls into the sandpaper recycling box along the sandpaper recycling trough.

[0007] Preferably, the sandpaper storage area is provided with multiple sandpaper storage positions of different specifications, and each sandpaper storage position contains multiple sandpapers of the corresponding specifications.

[0008] Preferably, the sandpaper storage area is provided with multiple sandpaper storage positions of different specifications, and each sandpaper storage position contains multiple sandpapers of the corresponding specifications.

[0009] Preferably, each of the sandpaper storage positions has multiple conical guide posts evenly distributed around its circumference to guide the rotary sanding mechanism in positioning and picking up new sandpaper.

[0010] Preferably, the sandpaper bonding detection area is provided with a sandpaper detection groove that communicates with the sandpaper recycling area. The sandpaper detection groove is recessed into the surface of the workbench, and the rotary polishing mechanism rotates in the sandpaper detection groove to detect the bonding stability of the new sandpaper.

[0011] Preferably, the rotary sanding mechanism includes a sanding motor and a sandpaper adhesive connector, wherein the sandpaper adhesive connector is attached to the back of the sandpaper via a Velcro structure; the output shaft of the sanding motor is connected to the sandpaper adhesive connector, thereby driving the sandpaper to rotate at high speed.

[0012] Preferably, an infrared emitter is installed in the grating sensing area and is adapted to a photoelectric receiving sensor installed in the sandpaper adhesive joint. The light spot emitted by the infrared emitter accurately positions the edge of the sandpaper, thereby detecting whether there is sandpaper on the sandpaper adhesive joint.

[0013] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model forms a continuous closed-loop process of sandpaper replacement-inspection-sanding by dividing the sandpaper into a sandpaper removal area, a storage area, an adhesion detection area, and a grating sensing area, which significantly improves work efficiency; at the same time, combined with the grating sensing area (such as an infrared transmitter + photoelectric receiving sensor), it realizes accurate detection of the presence of sandpaper, ensuring that subsequent actions are only performed after the sandpaper is correctly installed, avoiding the risk of misoperation. 2. The inclined design of the sandpaper removal blade in this utility model, combined with the recycling trough, allows the old sandpaper to be automatically peeled off and fall into the recycling bin as the robotic arm moves horizontally, reducing manual intervention; the sandpaper recycling area centrally manages the old sandpaper, taking into account both environmental protection and workshop cleanliness; and the sandpaper storage area is arranged in an array with different storage positions of different sizes to support diverse sanding needs; at the same time, the conical guide column further optimizes the positioning accuracy of new sandpaper, ensuring a high success rate of pickup.

[0016] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of the present invention.

[0017] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0019] This utility model provides a composite material trimming device based on a robotic arm. Please refer to [link / reference]. Figure 1 The system includes a frame 1, on which a worktable 2 is mounted. The worktable 2 is divided into a sandpaper removal area 3, a sandpaper storage area 4, a sandpaper adhesion detection area 5, and a grating sensing area 6. A sanding robot arm 7 is also provided on one side of the frame 1, and a rotary sanding mechanism 8 is installed at the end of the sanding robot arm 7. After the old sandpaper on the rotary sanding mechanism 8 is removed in the sandpaper removal area 3, new sandpaper is picked up in the sandpaper storage area 4 and, after being sensed by the grating sensing area 6, enters the sandpaper adhesion detection area 5 to detect the stability of the adhesion.

[0020] This invention forms a continuous closed-loop process of sandpaper replacement-inspection-sanding by dividing the sandpaper into a sandpaper removal area, a storage area, an adhesion detection area, and a grating sensing area, which significantly improves work efficiency. At the same time, by combining the grating sensing area with an infrared transmitter and a photoelectric receiver sensor, the presence of sandpaper can be accurately detected, ensuring that subsequent actions are performed only after the sandpaper is correctly installed, thus avoiding the risk of misoperation.

[0021] Specifically, the area below the workbench 2 is a sandpaper recycling area, and a sandpaper recycling box is placed in the sandpaper recycling area.

[0022] For further information, please refer to the following: Figure 2 The sandpaper removal area 3 is provided with a sandpaper recycling trough 31 that communicates with the sandpaper recycling area, and a sandpaper removal plate 32 is fixedly installed on the sandpaper recycling trough 31. One side of the sandpaper removal plate 32 is raised. When the rotary polishing mechanism 8 moves along the sandpaper removal plate 32 under the drive of the polishing robot arm 7, the sandpaper at the end of the rotary polishing mechanism 8 is separated and falls into the sandpaper recycling box along the sandpaper recycling trough 31.

[0023] The inclined design of the sandpaper removal blade in this invention, combined with the recycling trough, allows the old sandpaper to be automatically peeled off and fall into the recycling bin as the robotic arm moves horizontally, reducing manual intervention. The sandpaper recycling area centrally manages the old sandpaper, taking into account both environmental protection and workshop cleanliness. The sandpaper storage area is arranged in an array with different storage positions of various sizes to support diverse sanding needs. At the same time, the conical guide column further optimizes the positioning accuracy of the new sandpaper, ensuring a high success rate of pickup.

[0024] In this embodiment, multiple sandpaper storage positions 41 of different specifications are arranged in an array in the sandpaper storage area 4, and multiple sandpapers of the corresponding specifications are stacked in each sandpaper storage position 41; multiple conical guide posts 42 are evenly distributed around the circumference of each sandpaper storage position 41, thereby guiding the rotary grinding mechanism 8 to position and pick up new sandpaper.

[0025] Furthermore, the sandpaper bonding detection area 5 is provided with a sandpaper detection groove 51 that communicates with the sandpaper recycling area. The sandpaper detection groove 51 is recessed in the surface of the workbench 2. The rotary sanding mechanism 8 rotates in the sandpaper detection groove 51 to detect the bonding stability of the new sandpaper.

[0026] Specifically, such as Figure 3 As shown, the rotary sanding mechanism 8 includes a sanding motor 81 and a sandpaper adhesive joint 82. The sandpaper adhesive joint 82 is attached to the back of the sandpaper via a Velcro structure. The output shaft of the sanding motor 81 is connected to the sandpaper adhesive joint 82, thereby driving the sandpaper to rotate at high speed.

[0027] Furthermore, an infrared emitter is installed in the grating sensing area 6 and is adapted to the photoelectric receiving sensor installed in the sandpaper adhesive joint 82. The light spot emitted by the infrared emitter accurately positions the edge of the sandpaper, thereby detecting whether there is sandpaper on the sandpaper adhesive joint 82.

[0028] In this embodiment, the infrared transmitter is an OMRON E3Z-T81 with a small light spot for precise positioning of the sandpaper edge; the photoelectric receiving sensor is a KEYENCE GT2-P12K with background suppression technology (BGS mode) to ignore the reflection from the metal robotic arm.

[0029] During testing, if the sandpaper is present, the receiver receives a stable light intensity and outputs a high level (24V), which the PLC determines to be "normal". If the sandpaper is missing, the light intensity drops suddenly, at which point the receiver switches to a low level (0V) and confirms after a delay of 8ms. Finally, the PLC outputs an alarm signal.

[0030] The above description is only a description of the preferred embodiment of the present utility model and is not intended to limit the scope of the present utility model in any way. Any changes or modifications made by those skilled in the art based on the above disclosure shall fall within the protection scope of the claims.
