Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of multi-station plastic shell spraying device, specifically a multi-station plastic shell spraying device. Background Technology
[0002] The multi-station plastic shell spraying device is an automated surface treatment equipment. It adopts a modular multi-station design and uses a rotating platform or conveyor line to send plastic shells to different stations in sequence to achieve continuous flow operation. It can efficiently complete the spraying of plastic shells, significantly improve production efficiency and coating consistency, and is suitable for the batch spraying needs of plastic shells for electronic products, home appliances, automotive parts, etc.
[0003] In the conventional method of spraying plastic shells, the shell is placed on the surface of the worktable and then moved under the spray gun by a servo motor. However, in actual operation, when the worktable stops or accelerates suddenly, the inertia will cause a slight displacement between the shell and the fixture, resulting in blurred spraying boundaries and affecting the uniformity of the coating. To address this, we propose a multi-station plastic shell spraying device. Utility Model Content
[0004] The purpose of this invention is to provide a multi-station plastic shell spraying device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a multi-station plastic shell spraying device, comprising a base, a servo motor mounted on the surface of the base, support arms fixedly connected to both sides of the base, a spray gun mounted on the end of the support arm away from the base, a worktable fixedly connected to the output end of the servo motor, a limiting structure provided on the surface of the worktable, the limiting structure comprising several brackets, the brackets fixedly connected to the surface of the worktable, a bidirectional screw rotatably connected to the surface of the brackets, two drive arms threadedly connected to the surface of the bidirectional screws, the drive arms located on both sides of the brackets, and two limiting blocks fixedly connected to the surface of the drive arms.
[0006] The effect achieved by the above components is as follows: by setting a limiting structure, the rotating turntable drives the bidirectional screw to rotate, causing the limiting block on the drive arm to move and clamp the plastic shell, ensuring that the plastic shell will not have slight displacement between itself and the fixture due to the inertia generated by the sudden stop or acceleration of the worktable during the spraying process, thereby ensuring clear spraying boundaries and improving coating uniformity.
[0007] Preferably, a guide rod slides through the surface of the drive arm, and an extension plate is fixedly connected to one end of the guide rod. The extension plate is fixedly connected to the surface of the bracket.
[0008] The effect achieved by the above components is that the guide rod that slides through the surface of the drive arm plays a guiding role, ensuring that the drive arm moves smoothly and avoids shaking.
[0009] Preferably, a turntable is fixedly connected to the surface of the bidirectional screw, and the vertical cross-section of the turntable is in the shape of a cross.
[0010] The effect achieved by the above components is that the rotation of the turntable drives the rotation of the bidirectional screw, and the turntable facilitates the rotation of the bidirectional screw.
[0011] Preferably, the surface of the limiting block is provided with a plurality of rectangular grooves.
[0012] The effect achieved by the above components is that the rectangular grooves opened on the surface of the limiting block facilitate the discharge of paint sprayed onto the limiting block, thereby preventing paint from adhering to the surface of the limiting block.
[0013] Preferably, the surface of the base is provided with a collection structure, the collection structure includes several frames, each of which is fixedly connected to the surface of the workbench, a collection box is slidably inserted into the inner wall of the frame, and pins are slidably inserted into both sides of the frame, and several rectangular holes are opened on the surface of the workbench.
[0014] The effect achieved by the above components is as follows: by setting up a collection structure, when the plastic shell is sprayed, the frame is fixed on the workbench surface, and the rectangular holes on the workbench surface allow the paint that splashes or drips during the spraying process to fall into the collection box inside the frame, preventing the paint from scattering everywhere and keeping the working environment clean.
[0015] Preferably, the inner wall of the frame is fixedly connected with a plurality of fixing rods, and the arc surface of the fixing rods is fitted with a cylinder.
[0016] The above components achieve the following effects: the collection box slides along the surface of the cylinder, and the cylinder rotates on the surface of the fixed rod with the help of the collection box. The cylinder reduces the friction of the collection box when it moves, thus making it easier to take the collection box out or put it into the frame.
[0017] Preferably, a spring is fitted onto the surface of the pin, and the two ends of the spring are fixedly connected to the pin and the frame, respectively.
[0018] The effect achieved by the above components is that the spring prevents the pin from falling off the frame due to shaking.
[0019] Compared with the prior art, the beneficial effects of this utility model are:
[0020] This utility model, by setting a limiting structure, achieves the rotation of the turntable driving the bidirectional screw to rotate, causing the limiting block on the drive arm to move and clamp the plastic shell. As the worktable 5 rotates, the plastic shell at the upper limit moves sequentially to below the spray gun 4. The spray gun 4 sprays paint onto the surface of the rotating plastic shell, completing the spraying operation on the plastic shell. This prevents the plastic shell from shifting due to inertia between itself and the clamp when the worktable 5 stops or accelerates suddenly, ensuring clear spraying boundaries and uniform coating.
[0021] By setting up a collection structure, when spraying plastic shells, the frame is fixed to the workbench surface, and the rectangular holes on the workbench surface allow the paint that splashes or drips during the spraying process to fall into the collection box inside the frame, preventing the paint from scattering everywhere and keeping the working environment clean.

Detailed Implementation
[0028] 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.
[0029] Please see Figure 1-2This utility model provides a technical solution: a multi-station plastic shell spraying device, including a base 1, a servo motor 2 mounted on the surface of the base 1, support arms 3 fixedly connected to both sides of the base 1, a spray gun 4 mounted on the end of the support arm 3 away from the base 1, a worktable 5 fixedly connected to the output end of the servo motor 2, and a limiting structure 6 provided on the surface of the worktable 5. By setting the limiting structure 6, the rotating turntable 67 drives the bidirectional screw 62 to rotate, causing the limiting block 64 on the drive arm 63 to move and clamp the plastic shell, ensuring that the plastic shell will not have slight displacement between itself and the clamp due to the inertia generated by the sudden stop or acceleration of the worktable 5 during the spraying process, thereby ensuring clear spraying boundaries and improving coating uniformity. The surface of the base 1 is provided with a collection structure 7. By setting the collection structure 7, when spraying the plastic shell, the frame 71 is fixed to the surface of the worktable 5, and the rectangular holes 73 on the surface of the worktable 5 allow the paint that splashes or drips during the spraying process to fall into the collection box 72 inside the frame 71, preventing the paint from scattering everywhere and keeping the working environment clean.
[0030] Reference Figure 2 and Figure 3 As shown in this embodiment: the limiting structure 6 includes several brackets 61, which are fixedly connected to the surface of the worktable 5. A bidirectional screw 62 is rotatably connected to the surface of the bracket 61, and two drive arms 63 are threadedly connected to the surface of the bidirectional screw 62. The drive arms 63 are located on both sides of the bracket 61, and two limiting blocks 64 are fixedly connected to the surface of the drive arms 63. A guide rod 65 slides through the surface of the drive arm 63, and an extension plate 66 is fixedly connected to one end of the guide rod 65. The extension plate 66 is fixedly connected to the surface of the bracket 61. The guide rod 65 sliding through the surface of the drive arm 63 serves a guiding function, ensuring smooth movement of the drive arm 63 and preventing wobbling. A turntable 67 is fixedly connected to the surface of the bidirectional screw 62. The vertical cross-section of the turntable 67 is cross-shaped. The rotation of the turntable 67 drives the bidirectional screw 62 to rotate, thus facilitating the rotation of the bidirectional screw 62. The surface of the limiting block 64 is provided with a number of rectangular grooves 68. The rectangular grooves 68 on the surface of the limiting block 64 facilitate the discharge of the paint sprayed onto the limiting block 64, thereby preventing the paint from adhering to the surface of the limiting block 64.
[0031] Reference Figure 4 and Figure 5As shown, specifically, the collection structure 7 includes several frames 71, all of which are fixedly connected to the surface of the workbench 5. A collection box 72 is slidably inserted into the inner wall of each frame 71, and pins 74 are slidably inserted into both sides of each frame 71. Several rectangular holes 73 are formed on the surface of the workbench 5. Several fixing rods 75 are fixedly connected to the inner wall of each frame 71. A cylinder 76 is fitted onto the arc surface of each fixing rod 75. The collection box 72 slides along the surface of the cylinder 76, and the cylinder 76 rotates on the surface of the fixing rods 75 with the help of the collection box 72. The cylinder 76 reduces the friction of the collection box 72 during movement, thus facilitating the removal or placement of the collection box 72 into the frame 71. A spring 77 is fitted onto the surface of each pin 74, with both ends of the spring 77 fixedly connected to the pin 74 and the frame 71 respectively. The spring 77 prevents the pin 74 from falling off the frame 71 due to shaking.
[0032] Working principle: Before spraying, the turntable 67 is rotated. Since the turntable 67 is fixed on the bidirectional screw 62, the rotation of the turntable 67 drives the bidirectional screw 62 to rotate. Two drive arms 63 are threadedly connected to the surface of the bidirectional screw 62, and the drive arms 63 are located on both sides of the bracket 61. When the bidirectional screw 62 rotates, the two drive arms 63 will move in opposite directions along the threads of the bidirectional screw 62. The limiting blocks 64 fixedly connected to the surface of the drive arms 63 will move with the movement of the drive arms 63 until the distance between the two limiting blocks 64 matches the size of the plastic shell. At this time, the plastic shell is placed on the surface of the limiting blocks 64, thereby restricting the plastic shell. The guide that slides through the surface of the drive arms 63... The guide rod 65 serves as a guide to ensure the smooth movement of the drive arm 63 and prevent swaying. The rectangular groove 68 on the surface of the limit block 64 facilitates the discharge of paint sprayed onto the limit block 64, thereby preventing paint from adhering to the surface of the limit block 64. By restricting the plastic shell, the servo motor 2 is started. The output end of the servo motor 2 drives the worktable 5 to rotate. As the worktable 5 rotates, the plastic shell at the upper limit moves sequentially to below the spray gun 4. The spray gun 4 sprays paint onto the surface of the rotating plastic shell, completing the spraying operation on the plastic shell. This prevents the plastic shell from shifting due to inertia between itself and the fixture when the worktable 5 stops or accelerates suddenly, ensuring clear spraying boundaries and uniform coating.
[0033] During the spraying process, some paint may splash or drip. At this time, the collection structure 7 comes into play. The frame 71 is fixed to the surface of the workbench 5. The collection box 72 is slidably inserted into the inner wall of the frame 71. The rectangular hole 73 on the surface of the workbench 5 allows the splashed or dripping paint to fall into the collection box 72 through the rectangular hole 73. The pins 74 slidably inserted on both sides of the frame 71 are used to fix the position of the collection box 72 and prevent it from shaking during collection. The spring 77 on the surface of the pin 74 can keep the pin 74 fixed to the collection box 72. When it is necessary to remove the collection box 72 for cleaning, pull the collection box 72. The collection box 72 will slide along the surface of the cylinder 76. The cylinder 76 will rotate on the surface of the fixing rod 75 with the help of the movement of the collection box 72. The cylinder 76 reduces the friction of the collection box 72 when it moves, thereby making it easier to remove or put the collection box 72 into the frame 71.
