Description

Technical Field

[0001] The invention relates to the technical field of plastic part spraying processing, in particular to a support mechanism for rotary spraying of automobile plastic decorative parts. Background Art

[0002] The support mechanism for rotary spraying of automotive plastic decorative parts is a device used to secure and rotate the plastic decorative parts during the spraying process to ensure that the paint is evenly distributed on the workpiece surface. Securement prevents the plastic decorative parts from shaking during the spraying process, while rotation allows the paint to be more evenly distributed on the workpiece surface. There are two types of securement: vacuum adsorption and mechanical clamping. For flat plastic decorative parts or those with small curvatures, vacuum adsorption can be used for securement, which provides uniform pressure distribution and reduces damage to the workpiece surface. For plastic decorative parts with complex shapes, mechanical clamping arms with multi-point fixation are used. These clamping arms have fine-tuning capabilities to accommodate workpieces of different sizes and shapes. At the same time, the portion of the clamping arm that contacts the workpiece is covered with a protective layer to prevent scratches.

[0003] The existing support mechanism for rotary spraying of automobile plastic decorative parts is not convenient for firmly clamping plastic parts of various shapes during use. In order to adapt to plastic parts of different shapes, different clamps need to be replaced, which increases production costs. Summary of the Invention

[0019] Beneficial effects of the present invention:

[0020] 1. The present invention can drive the automobile plastic decorative parts to rotate through the rotating assembly to ensure spraying uniformity and provide an installation base for other components. The internal support assembly stably supports the plastic parts on the inside through vacuum adsorption and up and down lifting. The external support assembly can adjust the angle and height and is arranged around the rotating table to provide an installation platform for the expansion clamping assembly. The expansion clamping assembly can be adjusted and adaptively clamped to improve the stability of the installation of automobile plastic decorative parts.

[0021] 2. The expansion clamping assembly of the present invention is distributed on the external support rod surrounding the rotating table and is installed in different second threaded holes to adjust its height. The external support assembly is installed on different third threaded holes of the adjustment ring through the cooperation of T-slot and fastening bolts. The position of the expansion clamping assembly is adjusted to change the clamping angle, and the stepper motor is used to drive the mounting rod to rotate to change its inclination angle, so that the clamping points can be freely distributed in three-dimensional space. It is suitable for plastic parts with various contours such as round, arc-shaped, and irregular corners. The core of the expansion clamping assembly is a flexible clamping system composed of a conical airbag and a drawstring. A micro air pump injects gas into the inflation cavity, and the gas enters the conical airbag through the air injection channel to expand it. The drawstring prevents the airbag from becoming longer during inflation, so that the force is concentrated in the lateral expansion direction. The inflated airbag can fit the surface of the plastic part or be inserted into a hole, providing uniform and controllable clamping force. Flexible clamping avoids damage to the surface of the plastic part while adapting to structures with different curvatures, holes and edges.

[0022] 3. The present invention can fix the inside of automobile plastic decorative parts by setting an internal support component. The vacuum suction cup component in the internal support component adsorbs the bottom of the plastic part and cooperates with the first cylinder to drive the lifting seat to move up and down. At the same time, the first connecting rod and the second connecting rod maintain the lifting stability. The external expansion clamping component provides support and clamping force from the side to achieve internal and external clamping linkage, anti-slip, anti-overturning, and anti-deformation, and is suitable for lightweight or thin-walled plastic parts.

DETAILED DESCRIPTION

[0035] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0036] Reference Figures 1-11This embodiment provides a support mechanism for rotary spraying of automobile plastic decorative parts, including a rotating component 100, an internal support component 200 is threadedly connected to the top of the rotating component 100, an external support component 300 is installed around the rotating component 100, and a plurality of expansion clamping components 400 are sleeved on the surface of the external support component 300.

[0037] Before spraying the automobile plastic decoration, make sure that the rotating assembly 100, the internal support assembly 200, the external support assembly 300 and the expansion clamping assembly 400 are in normal condition, check whether the components are intact and ensure that they can work together smoothly, connect the internal support assembly 200 to the top of the rotating assembly 100 through threads, and provide an internal support point for the automobile plastic decoration to be sprayed to ensure its stability during the spraying process. Put the automobile plastic decoration on the internal support assembly 200 to ensure that the position of the decoration is correct and stable. Then, install the external support assembly 300 around the rotating assembly 100 and fix it on the external support assembly 200. Several expansion clamping assemblies 400 are mounted on the surface of the support assembly 300. The function of these assemblies is to further fix and position the decorative parts to be sprayed. At the same time, the expansion clamping assembly 400 applies uniform pressure to the decorative parts to ensure that the decorative parts will not be displaced or deformed during the spraying process. After preparation, start the rotating assembly 100 to make the entire device start to rotate slowly. This can ensure the uniformity of the coating during spraying and improve the spraying quality. When the spraying operation is completed, stop the rotating assembly 100, control the expansion clamping assembly 400, the external support assembly 300 and the internal support assembly 200 to loosen the automotive plastic decorative parts, and finally remove the sprayed automotive plastic decorative parts.

[0038] The rotating assembly 100 includes a rotating platform 101 . A plurality of first threaded holes 102 are formed on the top of the rotating platform 101 . A transmission assembly 105 is formed on the bottom of the rotating platform 101 .

[0039] The bottom of the transmission assembly 105 is fixedly connected to the base 104 , and a universal pulley 103 is installed around the bottom of the rotating platform 101 . The bottom of the universal pulley 103 is movably connected to the top of the base 104 .

[0040] The transmission component 105 is internally connected to a rotating rod 106, and the top of the rotating rod 106 is fixedly connected to the bottom of the rotating table 101. The transmission component 105 is internally connected to a large gear 107 and a small gear 108 that mesh with each other, and the large gear 107 is fixedly sleeved on the surface of the rotating rod 106. The top of the transmission component 105 is fixedly connected to a reduction motor 109, and the output shaft of the reduction motor 109 is fixedly connected to the small gear 108.

[0041] An adjusting ring 110 is fixedly connected to the bottom of the rotating platform 101 , and a third threaded hole 111 is formed around the bottom of the adjusting ring 110 .

[0042] Before using the rotating assembly 100, the internal support assembly 200 is threadedly connected to the rotating table 101 through the first threaded hole 102 opened on the top of the rotating table 101, and the external support assembly 300 is installed through the adjusting ring 110. Several first threaded holes 102 are evenly distributed on the top of the rotating table 101. By installing the internal support assembly 200 in different first threaded holes 102, different positions inside the plastic decorative part can be adsorbed and fixed. A third threaded hole 111 is opened around the bottom of the adjusting ring 110. By fixing the fastening bolts 310 in different third threaded holes 111, the rotating rod 309 can be fixed at different positions on the adjusting ring 110, thereby changing the position of the installation rod 301 around the rotating table 101 and fixing different positions on the surface of the plastic decorative part.

[0043] During the rotation of the rotating component 100, the reduction motor 109 starts working first, and its output shaft drives the small gear 108 to rotate. The small gear 108 engages with the large gear 107, causing the large gear 107 to rotate accordingly. The large gear 107 is fixedly mounted on the surface of the rotating rod 106, so the rotating rod 106 also starts to rotate. The top of the rotating rod 106 is fixedly connected to the bottom of the rotating table 101, thereby driving the rotating table 101 and all components thereon to rotate together. The universal pulley 103 is located at the bottom of the rotating table 101 and is movably connected to the base 104, which helps to reduce friction and make the rotation smoother. As the rotating table 101 slowly rotates, the robotic arm and spraying equipment begin to spray the plastic decorative parts of the car. Due to the uniformity of the rotation, the coating can be evenly distributed, improving the spraying quality. After the spraying is completed.

[0044] The internal support assembly 200 includes a support base 201 . A threaded head 207 is fixedly connected to the bottom of the support base 201 . The threaded head 207 is threadedly connected to the first threaded hole 102 .

[0046] The top of the support base 201 is rotatably connected to a first connecting rod 206 , the top of the first connecting rod 206 is rotatably connected to a second connecting rod 205 , and the top of the second connecting rod 205 is rotatably connected to the bottom of the lifting base 203 .

[0047] The threaded head 207 of the internal support assembly 200 is threadedly connected through the first threaded hole 102 on the top of the rotating table 101 to ensure that it is firmly fixed on the rotating table 101. The first cylinder 202 is activated, and the piston rod drives the lifting base 203 to move up and down to the appropriate position. The automobile plastic decorative part is sucked by the vacuum suction cup assembly 204 to ensure that the decorative part is firmly fixed on the top of the lifting base 203. During the movement of the lifting base 203, the first connecting rod 206 and the second connecting rod 205 are driven to rotate to assist the lifting base 203 in stable lifting.

[0048] The external support assembly 300 includes a mounting rod 301 , and a plurality of second threaded holes 302 are formed on a surface of the mounting rod 301 .

[0049] The bottom of the mounting rod 301 is rotatably connected to a motor base 303 , one side of the motor base 303 is fixedly connected to a telescopic rod 305 , a stepper motor 304 is fixedly mounted on the motor base 303 , and the output shaft of the stepper motor 304 is fixedly connected to the bottom of the mounting rod 301 .

[0050] The surface of the telescopic rod 305 is slidably connected to the rotating rod 309, and a second cylinder 311 is fixedly installed inside the rotating rod 309. The piston rod of the second cylinder 311 is fixedly connected to the telescopic rod 305. A T-slot 308 is opened on the top of the rotating rod 309. The T-slot 308 is sleeved on the surface of the adjusting ring 110 and movably connected thereto. A fastening bolt 310 is installed at the bottom of the telescopic rod 305.

By fastening the bolt 310 through the T-shaped slot 308 and threadedly connected to the third threaded hole 111, the position of the rotating rod 309 can be fine-tuned. After the rotating rod 309 is fixed, the mounting rod 301 is installed around the rotating table 101. The stepper motor 304 is fixedly installed through the motor base 303, and its output shaft is fixedly connected to the bottom of the mounting rod 301, which allows the mounting rod 301 to be adjusted in angle when needed. The telescopic rod 305 drives the mounting rod 301 By rotating, the expansion clamping assembly 400 can be tilted or flattened to adjust the working position and angle of the expansion clamping assembly 400, and the second cylinder 311 can drive the telescopic rod 305 to slide inside the rotating rod 309 to change the distance between the mounting rod 301 and the rotating table 101, and adjust the position of the expansion clamping assembly 400 so that several expansion clamping assemblies 400 can fix different positions of plastic decorative parts of different shapes. During the process of the rotating table 101 driving the adjusting ring 110 and the rotating rod 309 to rotate, the sliding member 306 at the bottom of the inclined rod 307 is movably connected to the surface of the base 104 to provide additional stability and support.

[0053] The expansion clamping assembly 400 includes a sleeve 401 , which is movably sleeved on the surface of the mounting rod 301 . A mounting bolt 402 is installed on the sleeve 401 , and the mounting bolt 402 is threadedly connected to the second threaded hole 302 .

[0055] Several sleeves 401 are movably mounted on the surface of the mounting rod 301 and are threadedly connected to the second threaded hole 302 using mounting bolts 402 to ensure that each expansion clamping assembly 400 is positioned correctly and stably. By installing it in different second threaded holes 302, the clamping height of the expansion clamping assembly 400 can be adjusted. By rotating the threaded rod 406, the threaded rod 406 rotates inside the threaded sleeve 404, and the extension length and clamping position of the expansion chuck 405 can be adjusted to make it closely contact and clamp the automotive plastic decorative parts to be sprayed.

[0056] An air filling chamber 408 is provided inside the fixed seat 403, one end of the threaded rod 406 extends into the inner cavity of the air filling chamber 408 and is fixedly connected to a piston 410, the surface of the piston 410 is slidably connected to the inner wall of the air filling chamber 408, and an air injection channel 409 is provided inside the piston 410 and the threaded rod 406, one end of the air injection channel 409 is connected to the air filling chamber 408, and the other end of the air injection channel 409 is connected to the expansion chuck 405.

[0057] The inner cavity of the inflation chamber 408 is fixedly connected with a partition 407, a micro air pump 412 and an electric exhaust valve 411. The partition 407 is located on the opposite side of the micro air pump 412 and the electric exhaust valve 411 to separate them. The air inlet end of the micro air pump 412 and the exhaust end of the electric exhaust valve 411 pass through the bottom of the fixed seat 403. The air outlet end of the micro air pump 412 passes through the partition 407 and is located at the air inlet end of the air injection channel 409.

[0058] The threaded rod 406 includes a clamping head 413, which is fixedly connected to the threaded rod 406. One end of the clamping head 413 is fixedly connected to a conical airbag 415. A through hole 417 is opened inside the clamping head 413, and the through hole 417 is connected to the inner cavity of the conical airbag 415 and the gas injection channel 409.

[0059] A drawstring 416 is provided around the inner wall of the conical airbag 415, one end of the drawstring 416 is fixedly connected to the conical head of the inner wall of the conical airbag 415, and the other end of the drawstring 416 is fixedly connected to the clamping head 413. Several drawstrings 416 are adapted to the shape of the inner cavity of the conical airbag 415 to pull and limit the conical head of the conical airbag 415 to prevent the conical head from becoming longer during the inflation process of the conical airbag 415, so that the surface of the conical airbag 415 can expand outward, thereby increasing the pressure of the contact part with the plastic decorative part.

[0060] A conical clamping portion 418 and an annular clamping portion 414 are provided on the surface of the clamping head 413 . The conical clamping portion 418 and the annular clamping portion 414 work together to contact parts of the plastic decorative part with different curvatures.

[0061] The internal support component 200 absorbs the bottom of the plastic decorative part to pull it downward. At this time, the expansion clamping component 400 is located at the bottom of the plastic decorative part, and the expansion clamping head 405 contacts the bottom edge of the plastic decorative part to support its bottom to prevent the edge from shaking during the spraying process. When the expansion clamping head 405 is working, gas is injected into the inflation cavity 408 through the micro air pump 412. The gas enters the conical airbag 415 through the injection channel 409. As the gas is injected, the conical airbag 415 expands outward, and the piston 410 seals the gas in the inflation cavity 408 to prevent the gas from passing through the injection channel If there is leakage at the connection between the channel 409 and the threaded sleeve 404, the drawstring 416 in the conical airbag 415 pulls and limits the conical head to prevent the conical airbag 415 from becoming longer, ensuring that its surface can expand outward and increase the pressure on the contact part with the plastic decorative part. When the plastic decorative part needs to be loosened, the electric exhaust valve 411 is opened, and the electric exhaust valve 411 discharges the high-pressure air inside the inflation chamber 408, the air injection channel 409 and the expansion chuck 405 to the outside, so that the conical airbag 415 retracts and resets. During the retraction of the conical airbag 415, the drawstring 416 pulls the conical airbag 415 to assist it in quickly resetting.

[0062] When the clamping head 413 is installed on the corners of the plastic decorative part, the conical clamping portion 418 and the annular clamping portion 414 can adapt to the corners of the plastic decorative part with different curvatures and provide a better clamping effect, and the conical airbag 415 is inserted into the hole of the plastic decorative part to expand and fix it.
