Description

Technical Field

[0001] The utility model relates to the technical field of plastic product processing, in particular to a plastic product processing platform. Background Art

[0002] Plastic product processing refers to the process of converting plastic raw materials into finished products with specific shapes, sizes, properties and colors through a series of physical or chemical processes. The painting process is often involved in the processing process. Painting can improve the appearance quality of plastic products, protect the product surface, and increase the added value and market competitiveness of products. It is a commonly used surface treatment method in plastic product processing.

[0003] A Chinese patent with authorization announcement number CN214864586U discloses a plastic product processing platform. The implementation principle of the device is that before painting, the workpiece needs to be clamped, and the limit guide rod is pushed in the direction of the limit fixing plate, so that the contraction block drives the pressing fixing plate to expand outward, and when a gap is generated between the pressing fixing plate and the limit fixing plate, the workpiece is placed on the gap and the limit guide rod is released. Under the action of the restoring force of the tightening spring, the contraction block drives the pressing fixing plate to contract in the direction of the contraction slot, thereby achieving the clamping effect. When the clamping is completed, the workpiece can be painted at multiple angles by rotating the fixed handle.

[0004] The shortcomings of the above-mentioned prior art solutions are: first, although the above-mentioned device can realize multi-angle painting of the workpiece, the installation process of the workpiece is relatively cumbersome, and it is necessary to push the limit guide rod, and the installation can only be carried out when a gap is generated between the pressing fixing plate and the limit fixing plate, which affects the implementation efficiency and increases the time cost. Secondly, after the workpiece surface is painted, it needs to be dried, and the above-mentioned prior art needs to first disassemble and separate the plastic workpiece, and then transfer it to the corresponding paint baking equipment for processing, which is relatively cumbersome, and the transfer process is also prone to collision and affect the paint surface.

DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 5As shown, a plastic product processing platform comprises a base 1, a stepper motor 7 is fixedly connected inside the base 1, a paint spraying mechanism 5 is arranged on one side of the base 1, a turntable 2 is rotatably arranged on the top of the base 1, and the output end of the stepper motor 7 is fixedly connected to the turntable 2. The device also comprises a heating mechanism 6, a supporting mechanism 3 and a transporting mechanism 4. A heating mechanism 6 is arranged on the other side of the base 1, the supporting mechanism 3 comprises a plurality of groups of supporting rods 301 uniformly surrounding and fixedly connected to the side of the turntable 2, and each group of supporting rods 301 is rotatably connected to a rotating shaft 302 at one end away from the turntable 2; the transporting mechanism 4 comprises a plurality of groups of interlocking blocks 404, an interlocking groove 303 matching the interlocking block 404 is provided in the middle of the rotating shaft 302, one end of each group of interlocking blocks 404 is fixedly connected to a cross plate 401, and two groups of U-shaped clamping plates 402 arranged in parallel are fixedly connected to the side of the cross plate 401 away from the interlocking block 404, and the U-shaped clamping plates 402 are responsible for carrying the workpiece, and each group The U-shaped clamping plate 402 is fixedly connected to the limiting strips 403 on both sides, and each set of limiting strips 403 is located between the corresponding two sets of U-shaped clamping plates 402. The limiting strips 403 play a limiting role to prevent the workpiece from sliding out from both sides; through the interlocking block 404 and the interlocking groove 303, the staff can easily replace the corresponding transportation mechanism 4 to adapt to different workpiece sizes, and push the workpiece along the limiting strips 403 between the two sets of parallel U-shaped clamping plates 402. The weight of the workpiece is supported by the U-shaped clamping plate 402, and the workpiece is driven by the stepper motor 7 to drive the workpiece into the paint spraying mechanism 5 to complete the paint spraying operation, and then enter the heating mechanism 6 to achieve heating, which promotes the volatilization of the volatile solvent, so that the workpiece after painting can be directly rotated into the heating mechanism 6 to complete the paint baking operation, without disassembly and then transfer, thereby avoiding affecting the paint on the surface of the workpiece. When the workpiece is taken away from the heating mechanism 6, it can be unloaded and the workpiece can enter the next process.

[0026] In some specific implementation schemes, in order to facilitate the disassembly of the transport mechanism 4, a connecting bolt 304 is horizontally passed through the rotating shaft 302, and a connecting hole 405 matching the connecting bolt 304 is opened on the engaging block 404. The connecting bolt 304 can pass through the connecting hole 405 to complete the locking of the engaging block 404 and the rotating shaft 302; when it is necessary to replace workpieces of different sizes, that is, it is necessary to replace the transport mechanism 4 of the corresponding size, put the engaging block 404 of the corresponding transport mechanism 4 into the engaging groove 303, and push the connecting bolt 304 to pass through the rotating shaft 302 and the connecting hole 405 for fixing, thereby realizing the locking of the engaging block 404 and the rotating shaft 302, and completing the installation of the transport mechanism 4.

[0027] In some specific embodiments, in order to reduce the impact of the device on the paint coating, a reserved groove 406 is opened at one end of the two groups of U-shaped clamps 402 away from the horizontal plate 401, and the width of the reserved groove 406 is the same as the width of the painted surface of the workpiece, and a gap is set between the two corresponding groups of limit bars 403; when the workpiece is unloaded, since the upper and lower surfaces of the workpiece are sprayed with coatings, the robotic arm needs to clamp and drag the workpiece through the gap between the limit bars 403. The reserved groove 406 set on the U-shaped clamp 402 can create a certain gap between the U-shaped clamp 402 plate body and the coating to avoid scratching the coating.

[0028] In some specific embodiments, in order to reduce the impact of painting on the environment, the paint spraying mechanism 5 includes a paint spraying box 501, which is arranged on one side of the base 1. A first inlet and outlet 502 that cooperates with the transportation mechanism 4 is opened on the side of the paint spraying box 501. The transportation mechanism 4 enters the paint spraying box 501 through the first inlet and outlet 502. A spray head 505 that cooperates with the transportation mechanism 4 is fixedly connected to the top of the paint spraying box 501, and the spray head 505 is located directly above the rotation path of the transportation mechanism 4; the spray head 505 is responsible for covering one side of the workpiece surface with a coating, and the paint spray box 501 provides a working space for the spray head 505, thereby reducing the impact on the environment.

[0029] In some specific implementation schemes, in order to realize double-sided painting of the workpiece, a driving motor 503 is fixedly connected to one side of the interior of the paint spray box 501, and a driving plate 504 matching the U-shaped clamping plate 402 is fixedly connected to the output end of the driving motor 503. The thickness of the driving plate 504 gradually decreases along the two sides, and the spacing between the two corresponding sets of U-shaped clamping plates 402 is the same as the middle thickness of the driving plate 504. The length of the limit bar 403 is less than the length of the U-shaped clamping plate 402, and one end of the limit bar 403 is fixedly connected to the cross plate 401; the transport mechanism 4 is brought to the spray head 505 under the action of the stepper motor 7. During the process directly below, two sets of parallel U-shaped clamps 402 will be moved to the upper and lower sides of the driving plate 504. At this time, the driving plate 504 is located between the two sets of U-shaped clamps 402. After the painting of one side of the workpiece is completed, the driving motor 503 rotates, and the output end of the driving motor 503 drives the driving plate 504 to rotate, and the driving plate 504 drives the two sets of U-shaped clamps 402 to rotate. The two sets of U-shaped clamps 402 drive the cross plate 401, the interlocking block 404, and the rotating shaft 302 to rotate 180°, and drive the workpiece to rotate 180°, and then paint the other side of the workpiece to achieve the effect of double-sided painting.

[0030] In some specific embodiments, in order to reduce the impact of subsequent operations on the coating surface, the heating mechanism 6 includes a heating box 601 arranged on the other side of the base 1, the heating box 601 is located on the rotation path of the transport mechanism 4, and a second inlet and outlet 602 that cooperates with the transport mechanism 4 is opened on the side of the heating box 601. The bottom and the top of the heating box 601 are fixedly connected with electric heating wires, and the surface of the electric heating wires is coated with flame retardant material, which can be alumina ceramics; after painting, the workpiece enters the second inlet and outlet 602 under the drive of the stepper motor 7, and the electric heating wire will generate heat after being energized. The power supply is controlled to ensure that the heating environment is between 30 and 40°C. At this temperature, the stability of the paint will not be affected, the volatile solvent will be volatilized, and the coating will form a solid surface faster, reducing the impact on the paint coating during subsequent unloading, transportation, and drying.

[0031] In some specific implementation schemes, in order to ensure smooth docking between the transport mechanism 4 and the driving plate 504, a correction plate 8 is fixedly connected to one side of the first inlet and outlet 502. Two groups of correction plates 8 are arranged, which are mirror-fixed near the position where the transport mechanism 4 enters the first inlet and outlet 502, and the two groups of correction plates 8 are smoothly arranged on one side close to the rotation path of the support mechanism 3; when the transport mechanism 4 is tilted and brought to the first inlet and outlet 502 by the stepper motor 7, the body of the correction plate 8 will press against one side of the U-shaped clamp 402, so that the U-shaped clamp 402 gradually drives the transport mechanism 4 as a whole to be parallel to the horizontal plane under the action of external force, thereby ensuring that the transport mechanism 4 can be smoothly docked with the driving plate 504 after entering the paint spray box 501, and an anti-slip rubber gasket is arranged between the support rod 301 and the rotating shaft 302 to increase the friction between the support rod 301 and the rotating shaft 302, thereby preventing the rotating shaft 302 from arbitrarily offsetting the support mechanism 3 before it approaches the correction plate 8.

[0032] In order to facilitate the understanding of the embodiments of the present invention by those skilled in the art, the working principle of the embodiments of the present invention is now described in combination with specific application scenarios:

[0033] When it is necessary to replace workpieces of different sizes, that is, it is necessary to replace the transport mechanism 4 of the corresponding size, put the fitting block 404 of the corresponding transport mechanism 4 into the fitting groove 303, push the connecting bolt 304 through the rotating shaft 302 and the connecting hole 405 for fixing, so as to achieve the locking of the fitting block 404 and the rotating shaft 302, and complete the installation of the transport mechanism 4. When unloading the workpiece, since the upper and lower surfaces of the workpiece are sprayed with coatings, the robot arm needs to clamp and drag the workpiece through the gap between the limit bars 403. The reserved groove 406 set on the U-shaped clamping plate 402 can make a certain gap between the plate body of the U-shaped clamping plate 402 and the coating to avoid scratching the coating;

[0034] The spray head 505 is responsible for coating one side of the workpiece surface. The spray box 501 provides a working space for the spray head 505, thereby reducing the impact on the environment. When the transport mechanism 4 is brought to the bottom of the spray head 505 by the stepper motor 7, the two sets of parallel U-shaped clamps 402 will be moved to the upper and lower sides of the driving plate 504. At this time, the driving plate 504 is located between the two sets of U-shaped clamps 402. After the painting of one side of the workpiece is completed, the drive motor 503 rotates, and the output end of the drive motor 503 drives the driving plate 504 to rotate. The driving plate 504 drives the two sets of U-shaped clamps 402 to rotate. The two sets of U-shaped clamps 402 drive the cross plate 401, the interlocking block 404, and the rotating shaft 302 to rotate 180°, and drive the workpiece to rotate 180°, and then the other side of the workpiece is painted to achieve the effect of double-sided painting.

[0035] After the painting is finished, the workpiece enters the second inlet and outlet 602 driven by the stepper motor 7. The electric heating wire will heat up after being energized. The power supply is controlled to ensure that the heating environment is 30-40°C. This temperature will not affect the stability of the paint, promote the volatilization of volatile solvents, and make the coating form a solid surface more quickly, reducing the impact on the paint coating during subsequent unloading, transportation, and drying. When the transport mechanism 4 is tilted and brought to the first inlet and outlet 502 by the stepper motor 7, the correction plate 8 will press against one side of the U-shaped clamp 402, so that the U-shaped clamp 402 gradually drives the transport mechanism 4 as a whole to be parallel to the horizontal plane under the action of external force, thereby ensuring that the transport mechanism 4 can be smoothly docked with the driving plate 504 after entering the paint spray box 501. An anti-slip rubber gasket is provided between the support rod 301 and the rotating shaft 302 to increase the friction between the support rod 301 and the rotating shaft 302, thereby preventing the rotating shaft 302 from arbitrarily offsetting the support mechanism 3 before approaching the correction plate 8.

[0036] The above is a detailed description of an embodiment of the utility model, but the content is only a preferred embodiment of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
