[0002] As an important part of the car interior, the surface quality of the car dashboard directly affects the visual quality and user experience of the whole vehicle. At present, most smart car dashboards are made by injection molding. After molding, the surface often has defects such as material lines, weld lines, and small burrs, which need to be polished to improve the smoothness and aesthetics.

[0003] Existing automotive dashboard polishing equipment often suffers from problems due to the rigid clamping mechanisms of traditional clamping systems. This makes it difficult to adapt to the curved or irregularly shaped structures of dashboards, leading to localized stress concentrations that can cause deformation or surface scratches in plastic parts. Furthermore, the polishing process generates a large amount of plastic debris and dust, which can easily fall onto the equipment and workpiece surfaces. This not only affects the polishing accuracy but also causes dust pollution in the workshop environment, potentially harming the health of operators.

[0004] To address this, a polishing device for injection molding of smart car dashboards is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a polishing device for injection molding of intelligent automotive dashboards. This device can solve the problems of existing automotive dashboard polishing devices, where the traditional clamping mechanisms are mostly rigid clamps, making it difficult to adapt to the curved or irregular structure of the dashboard. This can easily lead to local stress concentration, causing deformation or surface scratches of the plastic parts. Furthermore, the polishing operation generates a large amount of plastic debris and dust, which can easily fall onto the surface of the equipment and the workpiece, affecting the polishing accuracy and causing dust pollution in the workshop environment, thus endangering the health of the operators.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a polishing device for injection molding of intelligent automotive dashboards, comprising a base, a polishing robot mounted on the rear side of the top of the base, a polishing structure provided at the execution end of the polishing robot, a dust suction component provided on the outer side of the polishing structure, an adaptive clamping component provided at the top of the base, the adaptive clamping component comprising a moving cavity, the number of moving cavities being set to two and the two moving cavities being symmetrically arranged on both sides of the top of the base, a plurality of movable rods passing through the interior of the moving cavity, a contact ball fixedly connected to one end of the movable rod located outside the moving cavity, a limit block fixedly connected to one end of the movable rod located inside the moving cavity, and a tension spring sleeved on one end of the movable rod located inside the moving cavity, with both ends of the tension spring fixedly connected to the limit block and the inner wall of the moving cavity, respectively.

[0007] Preferably, the dust collection component includes an annular cavity, which is fixedly connected to the bottom of the polishing structure, and a dust collection port is provided at the bottom of the annular cavity.

[0008] Preferably, a corrugated connecting pipe is fixedly connected to the surface of the annular cavity, and an industrial vacuum cleaner is fixedly connected to the other end of the corrugated connecting pipe. The industrial vacuum cleaner is fixedly connected to the top of the base.

[0009] Preferably, the number of suction ports is set to multiple and evenly distributed, and the suction ports are arranged at an angle.

[0010] Preferably, a support block is fixedly connected to the top of the base, and a horizontal groove is provided on the front side of the support block.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. This application, by setting an adaptive clamping component, allows the contact ball to contact the surface of the car dashboard when the dashboard is placed between two moving cavities. The movable rod will extend and retract according to the contour of the car dashboard, and the tension spring will deform accordingly and generate a reverse tension force, so that the contact ball is always tightly attached to the surface of the car dashboard, thereby effectively preventing deformation of the plastic part or surface scratches.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-5 The present invention provides the following technical solution:

[0025] A polishing device for injection molding of a smart car dashboard includes a base 1. A polishing robot 2 is mounted on the rear side of the top of the base 1. The polishing robot 2 has a polishing structure 3 at its execution end. A dust suction component 4 is provided on the outside of the polishing structure 3. An adaptive clamping component 5 is provided on the top of the base 1. The adaptive clamping component 5 includes two moving cavities 501, which are symmetrically arranged on both sides of the top of the base 1. Multiple movable rods 502 pass through the interior of the moving cavities 501. A contact ball 503 is fixedly connected to one end of the movable rod 502 located outside the moving cavity 501. A limit block 504 is fixedly connected to one end of the movable rod 502 located inside the moving cavity 501. A tension spring 505 is sleeved on one end of the movable rod 502 located inside the moving cavity 501, and the two ends of the tension spring 505 are fixedly connected to the limit block 504 and the inner wall of the moving cavity 501, respectively.

[0026] In this embodiment: by setting the adaptive clamping component 5, the moving cavity 501 serves as the mounting carrier for components such as the movable rod 502 and the tension spring 505, providing protection and motion guidance for the internal components. Simultaneously, the two symmetrically arranged moving cavities 501 form a clamping space, achieving initial adaptation to instrument panels of different widths through relative movement. The movable rod 502 can freely extend and retract along the through hole of the moving cavity 501. When the contact ball 503 contacts the instrument panel surface, the movable rod 502 adapts to the curved or irregular contour of the instrument panel through changes in its extension and retraction, transmitting clamping force. The contact ball 503 is the component that directly contacts the instrument panel surface; its spherical design reduces the contact area with the workpiece. It can adapt to the curved surfaces of the instrument panel at different angles, ensuring the stability of point contact with the workpiece surface. The limiting block 504 is installed at one end of the movable rod 502 located inside the moving cavity 501. On the one hand, it limits the maximum extension of the movable rod 502. On the other hand, it serves as the connection fulcrum of the tension spring 505, which can transmit the tension of the tension spring 505 to the movable rod 502. The tension spring 505 is in a pre-tight state in its natural state. When the movable rod 502 is squeezed into the instrument panel by the contact ball 503, the tension spring 505 is further stretched and generates a reverse elastic force. The force is applied to the instrument panel through the movable rod 502 and the contact ball 503 to achieve flexible clamping, thereby meeting the processing requirements of different models of instrument panels.

[0027] Specifically, such as Figure 3 , Figure 4 As shown, the dust collection component 4 includes an annular cavity 401, which is fixedly connected to the bottom of the polishing structure 3, and a dust collection port 402 is provided at the bottom of the annular cavity 401.

[0028] Specifically, such as Figure 4As shown, a corrugated connecting pipe 403 is fixedly connected to the surface of the annular cavity 401, and an industrial vacuum cleaner 404 is fixedly connected to the other end of the corrugated connecting pipe 403. The industrial vacuum cleaner 404 is fixedly connected to the top of the base 1.

[0029] Specifically, such as Figure 4 As shown, the number of suction ports 402 is set to multiple and evenly distributed, and the suction ports 402 are set at an angle.

[0030] In this embodiment: by setting up a dust collection component 4, the annular cavity 401 serves as the core collecting component of the dust collection component 4, surrounding the polishing structure 3 in a ring shape. This allows for comprehensive coverage of the polishing area, ensuring that debris and dust are collected before they spread, preventing them from scattering. The suction port 402, located at the bottom of the annular cavity 401, is the entry point for debris and dust into the industrial vacuum cleaner 404. The multiple evenly distributed ports cover the entire working area of ​​the polishing disc 304, avoiding dead zones in the dust collection. The inclined design enhances the adsorption force on debris near the polishing point, improving dust collection efficiency and preventing debris from splashing due to centrifugal force. The corrugated connecting pipe 403 connects the annular cavity 401. The flexible pipe of the industrial vacuum cleaner 404, with its bendable and stretchable characteristics, can adapt to the multi-angle and multi-position changes of the polishing structure 3 as it moves with the polishing robot 2, ensuring that the dust suction path is always unobstructed and will not break or become blocked due to mechanical pulling. The industrial vacuum cleaner 404 can provide a powerful negative pressure suction source, and through the corrugated connecting pipe 403, a negative pressure environment is formed in the annular cavity 401, which sucks in the polishing debris and dust from the suction port 402. After passing through the annular cavity 401 and the corrugated connecting pipe 403, the debris and dust are finally collected in the dust bag inside the industrial vacuum cleaner 404, achieving thorough removal of pollutants, thereby protecting the workshop environment and the health of the operators.

[0031] Specifically, such as Figure 1 , Figure 2 As shown, a support block 6 is fixedly connected to the top of the base 1. A horizontal groove 7 is provided on the front side of the support block 6. A bidirectional screw 8 is rotatably connected inside the horizontal groove 7 through a bearing. Both ends of the surface of the bidirectional screw 8 are threadedly connected to screw blocks 9. The screw blocks 9 are used in conjunction with the horizontal groove 7.

[0032] Specifically, such as Figure 2 As shown, a linkage frame 10 is fixedly connected to the front side of the screw block 9, and the other end of the linkage frame 10 is fixedly connected to the top of the moving cavity 501.

[0033] In this embodiment: Through the above settings, the support block 6 can provide a stable support point for the bidirectional screw 8, ensuring the rigidity and stability of the structure during the adjustment process. The transverse groove 7 is opened on the front side of the support block 6, and its shape matches the screw block 9. It can restrict the degree of freedom of movement of the screw block 9, so that the screw block 9 can only move horizontally along the length direction of the transverse groove 7, and cannot rotate with the rotation of the bidirectional screw 8, ensuring the accuracy of the adjustment direction. When the bidirectional screw 8 rotates, the screw blocks 9 at both ends will move synchronously in opposite directions along the bidirectional screw 8 under the action of the thread, thereby realizing the adjustment of the distance between the two moving cavities 501. When the moving cavity 501 moves, it will drive the moving cavity 501 to move synchronously through the linkage frame 10, so as to center and clamp various models and specifications of instrument panels.

[0034] Specifically, such as Figure 3 As shown, the polishing structure 3 includes a support disk 301, a drive motor 302 is fixedly installed inside the support disk 301, the output shaft of the drive motor 302 is fixedly connected to a fixed seat 303, a polishing disc 304 is bolted to the bottom of the fixed seat 303, and an annular cavity 401 is fixedly connected to the bottom of the support disk 301.

[0035] Specifically, such as Figure 2 As shown, a servo motor 11 is fixedly installed on the right side of the support block 6, and the output shaft of the servo motor 11 is fixedly connected to the bidirectional screw 8.

[0036] In this embodiment: With the above configuration, the support plate 301 is the basic load-bearing component of the polishing structure 3, providing an installation platform for the drive motor 302 and the annular cavity 401. It also connects to the execution end of the polishing robot 2, driving the entire polishing structure 3 to move with the robot, ensuring the flexibility of the polishing operation. The drive motor 302 is the power source for the polishing action; through the rotation of its output shaft, it drives the fixed seat 303 and the polishing disc 304 to rotate at high speed, providing polishing power to the polishing disc 304 to remove defects from the dashboard surface. The fixed seat 303 connects the output shaft of the drive motor 302 to the polishing disc 304. The intermediate connector of the polishing disc 304 serves to fix and transmit torque. It can fix the polishing disc 304 by bolting, which facilitates quick replacement of different types of polishing discs 304 to adapt to different polishing processes. The polishing disc 304 is the grinding component that directly contacts the surface of the instrument panel. Depending on the material and grit size, it can achieve the processing effect from coarse grinding to fine grinding, remove injection molding defects of the instrument panel and improve the surface finish. The servo motor 11 is fixedly connected to the bidirectional screw 8 through the output shaft, which can precisely control the rotation direction and angle of the bidirectional screw 8, thereby enabling precise adjustment of the distance between the two moving cavities 501.

[0037] Working principle: First, the operator places the smart car dashboard to be polished between the two moving cavities 501 on the top of the base 1. Then, the servo motor 11 is started. The output shaft of the servo motor 11 drives the bidirectional screw 8 to rotate in the transverse groove 7 of the support block 6. Since the screw block 9 is threadedly connected to the bidirectional screw 8 and cannot rotate due to the restriction of the transverse groove 7, the screw blocks 9 at both ends will move synchronously in opposite directions along the bidirectional screw 8. Through the linkage frame 10, the two moving cavities 501 are driven to move closer to each other. During the process of the moving cavities 501 moving closer, the contact ball 503 first contacts the dashboard surface. As the moving cavities 501 continue to move closer, the movable rod 502 will be squeezed and pushed towards the surface. The moving cavity 501 contracts internally, causing the limiting block 504 to move and stretch the tension spring 505. The reverse elastic force generated by the tension spring 505 acts on the instrument panel through the movable rod 502 and the contact ball 503. Multiple movable rods 502 and contact balls 503 adaptively extend and retract according to the curved surface or irregular contour of the instrument panel, achieving flexible and stable clamping of the instrument panel. After clamping, the polishing robot 2 and polishing structure 3 are activated. The polishing robot 2 drives the polishing structure 3 to move to the appropriate polishing position. The drive motor 302 in the support plate 301 starts, and its output shaft drives the fixed seat 303 and the polishing pad 304 to rotate at high speed, polishing the surface of the instrument panel. During the polishing process, an industrial vacuum cleaner 404 is simultaneously activated. The industrial vacuum cleaner 404 creates negative pressure within the annular cavity 401 via a corrugated connecting pipe 403. Since the annular cavity 401 is fixed to the bottom of the support plate 301 and surrounds the polishing disc 304, its multiple evenly distributed inclined suction ports 402 can be aimed at the polishing area from all directions. This allows plastic debris and dust generated during polishing to enter the annular cavity 401 through the suction ports 402 under negative pressure, and then be sucked into the industrial vacuum cleaner 404 for collection via the corrugated connecting pipe 403. The corrugated connecting pipe 403 can flexibly bend and extend as the polishing robot 2 moves the polishing structure 3. To ensure a continuous and stable dust collection process, once one area is polished, the polishing robot 2 moves the polishing structure 3 to the next area that needs polishing, repeating the polishing and dust collection process until all areas of the dashboard are polished. After polishing, the drive motor 302 and the industrial vacuum cleaner 404 are turned off, the polishing disc 304 stops rotating, and the dust collection process ends. Then, the servo motor 11 is reversed, and the bidirectional screw 8 drives the screw block 9 and the linkage frame 10 to move the two moving cavities 501 away from each other. The tension spring 505 returns to its original state, and the movable rod 502 and the contact ball 503 separate from the dashboard. The operator can then remove the polished dashboard.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
