Description

Technical Field

[0001] This invention relates to the field of robot spraying technology, and in particular to a surface spraying device for ball toys with a limiting structure. Background Technology

[0002] With the improvement of people's living standards and the increasing emphasis on children's entertainment and education, ball toys, as products that combine entertainment and functionality, have seen a continuous increase in market demand. From common rubber bouncy balls and PVC inflatable balls to intelligent sensor balls with special functions, their applications cover multiple fields such as children's entertainment, sports training, and parent-child interaction. In the production and processing of ball toys, spraying is one of the key processes. This process is usually carried out after the toy ball base is formed. It is mainly carried out by spraying robots to perform specific automated spraying processes to form a uniform coating on the surface of the ball. This coating not only gives the ball toys rich colors and patterns, enhancing their visual appeal, but also provides protective functions such as wear resistance, anti-slip, anti-fading, and antibacterial properties, extending the lifespan of the toy and enhancing its safety.

[0003] However, the current production processes in the painting and processing of ball toys still have significant shortcomings, which restrict the improvement of product quality and production adaptability. Specific problems are as follows: First, the existing spraying process can only achieve full coverage of the entire outer surface of the toy ball, and cannot accurately limit the spraying area according to production needs (such as partial pattern forming, division of specific functional areas, etc.). This not only fails to meet the diverse product design needs, but may also cause paint waste due to unnecessary spraying, increasing production costs. Secondly, after a single spraying process, incompletely atomized paint may remain inside the spraying robot's nozzle and at the spray nozzle. This residual paint will gradually accumulate and drip down under gravity. If it drips onto the surface of a toy ball that has been partially sprayed or is yet to be sprayed, it can easily form irregular paint accumulation, drips, or discolored spots on the surface of the ball, seriously damaging the uniformity and integrity of the coating, directly leading to a decline in product spraying quality and a reduction in product qualification rate. Summary of the Invention

[0004] To address the above problems, one objective of this invention is to overcome these shortcomings, and more specifically, to provide a ball toy surface spraying device with a limiting structure, which can adjust the spraying range on the ball toy surface according to usage requirements, thereby processing ball toys of different styles, and the movable nozzle can retract inward after spraying to prevent residual spray paint from dripping.

[0015] This invention provides a surface coating device for ball toys with a limiting structure, which has the following advantages: 1. In this invention, a swinging component is installed in the assembly slot within the fixed frame and a spherical toy is fixed in conjunction with a suction cup clamp. The area that does not need to be painted is pre-positioned downwards. At the same time, the position of the movable plate on the base rod is changed by rotating the adjusting screw, thereby adjusting the range of motion of the swinging component in the assembly slot. During painting, the swinging component drives the spherical toy to rotate and swing at a limited angle, so that only a part of the spherical toy is exposed to the nozzle, thereby achieving precise painting of specific areas of the sphere. This not only meets the diverse design needs such as local pattern forming and functional area division, but also effectively avoids unnecessary paint painting and saves production costs. 2. In this invention, a rotating frame with a spray nozzle is installed in the mounting slot within the mounting bracket, and the retraction and extension of the rotating frame are controlled by an electric cylinder driving a fixing component. When spraying a spherical toy, the electric cylinder pushes the fixing component downward, causing the bottom of the rotating frame to flip outward, exposing the spray nozzle for spraying. After spraying is completed, the electric cylinder drives the fixing component upward, and the rotating frame retracts the spray nozzle to the inside of the mounting bracket. At this time, any remaining incompletely atomized paint on the spray nozzle can drip directly into the collecting component, effectively preventing paint from dripping onto the surface of the sprayed or unsprayed toy ball, preventing uneven and incomplete coatings caused by drips or discolored spots, improving product spraying quality, and significantly increasing the product qualification rate.

The degree of movement of the swinging component 301 in the assembly groove 203 varies depending on the position of the movable plate 303, thus achieving painting processing of different areas of the spherical toy.

[0032] As a third embodiment of the present invention, based on embodiment 1, such as Figure 8 and Figure 9As shown, the spraying unit 4 includes: a mounting frame 401, a mounting groove 4011, an electric cylinder 402, and a collecting component 4021; the mounting frame 401 has a hollow interior; the mounting groove 4011 is arranged in a ring shape on the lower outer side of the mounting frame 401; the electric cylinder 402 is fixedly installed inside the mounting frame 401, and the collecting component 4021 is threadedly installed at the end of the piston rod below the electric cylinder 402; a tilting frame 403, a spray head 4031, and a fixing rod 4032; the tilting frame 403 is rotatably installed in the mounting groove 4011. The nozzle 4031 is fixedly mounted on the tilting frame 403, and when the tilting frame 403 is retracted into the mounting frame 401, the lower end of the nozzle 4031 is adjacent to the collector 4021; the fixing rod 4032 is fixedly mounted on the upper end of the tilting frame 403; the fixing member 404 and the mating groove 4041; the fixing member 404 is fixedly mounted on the piston rod below the electric cylinder 402; the mating groove 4041 is arranged in a ring inside the fixing member 404, and the mating groove 4041 is correspondingly arranged with the mounting groove 4011, and the mating groove 4041... The device slides in conjunction with the fixed rod 4032; a mounting bracket 401 is provided, within which an electric cylinder 402 can be installed; a mounting groove 4011 is provided, through which the tilting frame 403 can be movably installed onto the inner side of the mounting bracket 401; an electric cylinder 402 is provided, by moving the electric cylinder 402, the tilting frame 403 can be rotated within the mounting groove 4011; a disc-shaped collector 4021 is provided, capable of collecting spray paint dripping from the nozzle 4031; the tilting frame 403 is provided, allowing the tilting frame to... A nozzle 4031 is installed on 403; the nozzle 4031 allows the paint to be sprayed onto the spherical toy; a fixing rod 4032 is provided, which allows the fixing member 404 to move and push the fixing rod 4032, causing the flipping frame 403 to flip within the mounting groove 4011; a fixing member 404 is provided, and a mating groove 4041 is provided within the fixing member 404. By moving the fixing member 404, the fixing rod 4032 slides along the mating groove 4041, allowing the flipping frame 403 to rotate.

[0033] This application involves rotating a flip frame 403 with a spray nozzle 4031 in the mounting groove 4011 within the mounting frame 401. The fixed rod 4032 on the flip frame 403 is slidably connected to the mating groove 4041. When spraying a spherical toy, the electric cylinder 402 pushes the fixed member 404 downward through the piston rod, causing the bottom of the flip frame 403 to flip outward and the spray nozzle 4031 to be exposed for spraying. When the spraying is completed, the electric cylinder 402 drives the fixed member 404 upward through the piston rod, and causes the flip frame 403 to retract the spray nozzle 4031. After the flip frame 403 retracts, the spray nozzle 4031 located inside the mounting frame 401 can collect the residual spray paint in the collection member 4021, preventing it from dripping onto the spherical toy.

[0034] The specific usage and function of this embodiment are as follows: In this invention, such as Figures 1 to 9 As shown, the lower end of the vertical frame 102 is inserted into the slot 1011 of the base frame 101, causing both ends of the movable rod 103 to slide along the slide groove 1021 of the vertical frame 102. By pressing down the movable rod 103, the insertion rod 1031 passes through the limiting hole 2012 in the side plate 2011 of the fixed frame 201, completing the fixed connection between the mounting part 1 and the limiting part 2. Next, the movable frame 104 is installed in the top groove 1022 at the top of the vertical frame 102 via a screw, and the two sides of the mounting frame 401 are... Insert the ball toy into the positioning slot 1041 of the movable frame 104, and then place it on the flared structure at the upper end of the suction cup clamp 304. The side hole 3041 is connected to an air pump for suction, so that the ball toy is adsorbed onto the suction cup clamp 304. Place the area that does not need to be sprayed downwards. According to the spraying area requirements, rotate the adjusting screw 302 to move the movable plate 303 to the corresponding position within the base rod 3011, thereby determining the position of the swinging part 301 within the assembly slot 203. When the spraying operation begins, the electric cylinder 402 is activated, and its piston rod pushes the fixing member 404 downward. The mating groove 4041 in the fixing member 404 pushes the fixing rod 4032 on the flipping frame 403, causing the bottom of the flipping frame 403 to flip outward, exposing the spray head 4031, and spraying the spherical toy. By shaking the bottom rod 3011, the swinging member 301 rotates in the assembly groove 203, and the movable plate 303 moves in contact with the limiting cover 204, bringing... The moving spherical toy swings at a set angle, and the spray nozzle 4031 sprays a portion of the spherical toy. After the spraying is completed, the piston rod of the electric cylinder 402 drives the fixing part 404 to move upward, so that the flipping frame 403 drives the spray nozzle 4031 to retract to the inside of the mounting frame 401. The paint residue on the spray nozzle 4031 drips into the collecting part 4021. Then the air pump connected to the side hole 3041 is turned off, and the sprayed spherical toy is removed. This completes the spraying process of the spherical toy.
