Description

Technical Field

[0001] This utility model relates to the field of badminton racket spray painting, specifically an automated spray painting device for badminton racket processing. Background Technology

[0002] The badminton racket spray painting device is used to uniformly coat the surface of the racket frame and shaft with paint to enhance its appearance and increase its durability. The device usually consists of core components such as a spraying system, a rotating clamp, a paint supply system, and a control unit. By precisely controlling the spraying path, air pressure, and paint flow, it ensures that the paint film thickness is uniform and adheres firmly.

[0003] The main body of a badminton racket is usually made of carbon fiber composite material. The frame and shaft have a hollow design, mainly to reduce the overall weight of the racket and improve its flexibility. Traditional badminton racket painting equipment usually uses a clamping structure to fix the bottom of the shaft to ensure stability during spraying. However, this fixing method causes the clamped part of the shaft to be physically blocked during the spraying process, preventing it from being evenly covered by paint. This results in a significant color difference between the clamped part and the surrounding coating area, which damages the uniformity of the badminton racket's appearance and requires additional touch-up painting, thus reducing the efficiency of badminton racket painting.

This is mainly to reduce the overall weight of the racket and improve its flexibility. Traditional badminton racket painting equipment typically uses a clamping structure to fix the bottom of the shaft to ensure stability during spraying. However, this fixing method causes the clamped part of the shaft to be physically blocked during the spraying process, preventing it from being evenly covered by paint. This results in a significant color difference between the clamped part and the surrounding coating area, disrupting the uniformity of the badminton racket's appearance and requiring additional touch-up painting processes, thus reducing the efficiency of badminton racket painting. This invention proposes an automated painting equipment for badminton racket processing.

One end of each push rod is fixedly connected to one side of a moving block, and the other end of each push rod is rotatably connected to a roller. The surface of the roller contacts the surface of the rotating block. A spring is sleeved on the surface of each push rod.

[0012] The advantages of this utility model are: This invention utilizes an internal support mechanism. First, the batter is fitted onto the outer surface of four internal support blocks initially in a retracted state. Then, a rotating shaft drives a rotating block to rotate. The rotating block has a groove on its surface. As the rotating block rotates, it pushes a push rod outward, converting rotational motion into linear thrust. The outward-pushing push rod drives a connected moving block to move outward synchronously. The moving block then causes the internal support blocks to expand outward. By having the surface of the expanded internal support blocks contact the inner wall of the batter, the batter is fixed, preventing it from loosening or shifting during painting. This allows the outside of the batter to be completely exposed to the painting environment, reducing paint dead zones, ensuring uniform paint coverage, improving coating integrity and appearance consistency, and enhancing stability during painting.

[0017] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail. This application discloses an automated painting device for badminton racket manufacturing. (Refer to...) Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 An automated painting equipment for badminton racket processing includes a housing 1, a painting device 3 installed in the inner cavity of the housing 1, and an inner support mechanism 2 installed on the inner wall of the housing 1, the number of which is several. The internal support mechanism 2 includes a chassis 201, which is disposed within the inner cavity of the housing 1. A bracket 203 is fixedly connected to the top of the chassis 201, and a positioning frame 204 is also fixedly connected to the top of the chassis 201. A rotating shaft 205 is rotatably connected to the inner wall of the chassis 201. One end of the rotating shaft 205 extends through to the outside of the chassis 201 and is rotatably connected to the inner wall of the bracket 203. A rotating block 206 is fixedly connected to the surface of the rotating shaft 205. The chassis 201 slides between the opposite sides of the bracket 203. Four movable blocks 209 are connected, and each of the four movable blocks 209 has an inner support block 202 fixedly connected to its top. Four push rods 207 are slidably connected to the inner wall of the positioning frame 204. One end of each push rod 207 is fixedly connected to one side of a movable block 209, and the other end of each push rod 207 is rotatably connected to a roller 208. The surface of the roller 208 contacts the surface of the rotating block 206, and the surface of the push rod 207... A spring 210 is fitted, with one end of the spring 210 fixedly connected to the surface of the positioning frame 204 and the other end of the spring 210 fixedly connected to one side of the moving block 209. By setting the inner support mechanism 2, the batter is first fitted into the outer surface of the four inner support blocks 202, which are initially in a retracted state. Then, the rotating shaft 205 drives the rotating block 206 to rotate. The surface of the rotating block 206 is provided with a groove. As the rotating block 206 rotates, it pushes the push rod 207 outward, thereby converting the rotational motion into linear thrust. The outward push rod 207 drives the connected moving block 209 to move outward synchronously. The moving block 209 then drives the inner support block 202 to expand outward. The surface of the expanded inner support block 202 contacts the inner wall of the batter, thereby fixing the batter and preventing it from loosening or shifting during the painting process. This allows the outside of the batter to be completely exposed to the painting environment, reducing dead corners in the painting process, ensuring uniform paint coverage, improving the integrity and appearance consistency of the coating, and enhancing the stability during the painting process.

[0018] Reference Figure 1 and Figure 2 The inner wall of the housing 1 is fixedly connected to a protective shell 18. The inner wall of the housing 1 is provided with a base 4. The top of the base 4 is fixedly connected to a fixing plate 5. The top of the fixing plate 5 is provided with a mounting plate 6. The chassis 201 is fixedly connected to the top of the mounting plate 6. Through the setting of the base 4, the fixing plate 5 and the mounting plate 6, the inner support mechanism 2 can be supported and fixed to prevent the inner support mechanism 2 from shaking or shifting, and to ensure the stability of the inner support mechanism 2 during use. Reference Figure 3The top of the fixed plate 5 is fixedly connected with two positioning posts 11. The positioning posts 11 penetrate into the inner wall of the mounting plate 6. The mounting plate 6 is movably connected to the top of the fixed plate 5 through the positioning posts 11. The positioning posts 11 make it easy for users to remove the mounting plate 6 from the top of the fixed plate 5, making it easy to remove the fixing of the mounting plate 6, so that workers can replace the entire mounting plate 6 and paint different batches of the racket. Reference Figure 3 and Figure 6 An electric telescopic rod 12 is fixedly connected to the top of the fixed plate 5. A rack 13 is fixedly connected to the telescopic end of the electric telescopic rod 12. A gear 17 is fixedly connected to the surface of the rotating shaft 205. The surface of the rack 13 meshes with the surface of the gear 17. Through the setting of the electric telescopic rod 12 and the gear 17, a driving force can be provided to the rotating shaft 205, so that the rotating shaft 205 can drive the rotating block 206 to rotate, thereby unfolding the inner support block 202 and ensuring the smooth rotation of the rotating shaft 205. Reference Figure 3 and Figure 4 A guide block 16 is fixedly connected to the bottom of the rack 13, and a guide groove 15 is provided on the top of the mounting plate 6. The surface of the guide block 16 contacts the inner wall of the guide groove 15. By setting the guide block 16 and the guide groove 15, the rack 13 can be limited and moved along the preset path to prevent the rack 13 from deviating. Reference Figure 5 Rubber pads 7 are fixedly connected to the surfaces of the four inner support blocks 202. A connecting rod 14 is fixedly connected between the opposite sides of the two rackets 13. The rubber pads 7 increase the friction between the inner support blocks 202 and the inner wall of the racket shaft. At the same time, the rubber pads 7 are elastic and can deform when the inner support blocks 202 expand, so as to better fit the inner wall of the racket shaft. The connecting rod 14 can transmit the thrust of the electric telescopic rod 12, so that multiple rackets 13 can be connected and ensure that multiple rackets 13 can move synchronously. Reference Figure 2A motor 8 is fixedly connected to the inner wall of the protective shell 18. The output end of the motor 8 extends to the outside of the protective shell 18. A threaded rod 9 is fixedly connected to the output end of the motor 8. One end of the threaded rod 9 is rotatably connected to the inner wall of the box 1. The inner wall of the base 4 is threadedly connected to the surface of the threaded rod 9. A slide rod 10 is fixedly connected to one side of the protective shell 18. One end of the slide rod 10 is fixedly connected to the inner wall of the box 1. The inner wall of the base 4 is slidably connected to the surface of the slide rod 10. The base 4 is slidably connected to the inner wall of the box 1 through the motor 8, the threaded rod 9, and the slide rod 10. Through the arrangement of the motor 8, the threaded rod 9, and the slide rod 10, the base 4 is driven by the motor 8 to rotate the threaded rod 9, thereby moving the base 4. At the same time, the base 4 will slide on the surface of the slide rod 10. The slide rod 10 will constrain the base 4, so that the base 4 can move stably in and out of the paint spraying box 1, making it convenient for the user to remove the mounting plate 6 and replace the painted spraying handle.

[0019] Working Principle: When the automated badminton racket painting equipment is in operation, the racket is first fixed onto the fixture. After the sensor confirms the installation is in place, the racket shaft enters the painting area. A multi-axis robotic arm drives the electrostatic atomizing nozzle to move along a preset trajectory. The paint is adsorbed onto the racket surface under the action of high-voltage electrostatics. This is existing technology and will not be elaborated further. The operator first inserts the unpainted racket shaft onto the surface of the retracted inner support block 202, and then activates the electric telescopic rod 12 via an external control switch. The electric telescopic rod 12 is powered by an external power source. The extension end of the electric telescopic rod 12 extends, thereby pushing the racket 13 forward. Rack 13 moves along the dovetail groove via the dovetail block. The forward-pushed rack 13 transmits its thrust to the next rack 13 via the connecting rod 14. Rack 13 meshes with gear 17 on the surface of the rotating shaft 205. When rack 13 moves, it drives the meshing gear 17 to rotate. The rotation of gear 17 drives the rotating shaft 205 to rotate synchronously. The rotating shaft 205 can transmit the rotational force of gear 17 to the rotating block 206. In the retracted state, push rod 207 connects to roller 208 located in the groove of rotating block 206. As rotating block 206 rotates, it pushes the roller 208 and the rotating block 206 to rotate. The push rod 207 connected to 206 moves outward. The roller 208 reduces the friction between the rotating block 206 and the push rod 207, making the push rod 207's extension process smoother. The positioning bracket 204 limits the push rod 207, allowing it to move linearly. As the push rod 207 extends, it drives the moving block 209 to expand outward synchronously, thereby causing the inner support block 202 to expand as well. This causes the surface of the inner support block 202 to contact the inner wall of the racket shaft, thus fixing the racket shaft. Simultaneously with the outward expansion of the moving block 209 and the push rod 207, the spring 210 is stretched. The stretched spring 210... Storing elastic potential energy, when the inner support block 202 needs to fix the racket shaft, the telescopic end of the electric telescopic rod 12 retracts, driving the rack 13 to move backward. The backward movement of the rack 13 drives the meshing gear 17 to rotate in the opposite direction, causing the rotating block 206 to rotate. This removes the limiting effect of the rotating block 206 on the push rod 207. The compressed spring 210 will rebound, causing the push rod 207, the moving block 209, and the inner support block 202 to automatically retract. The roller 208 will return to the groove of the rotating block 206, causing the inner support block 202 to disengage from the inner wall of the racket shaft, thus releasing the fixation on the inner wall of the racket shaft.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
