[0034] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0035] Reference Figure 1-3 This utility model discloses a flipping mechanism, comprising: a frame 1 and clamping arms 10 disposed opposite to each other on the frame 1; a mounting base 30 rotatably disposed at the end of the clamping arms 10, wherein a clamping cylinder 40 for clamping a workpiece is mounted on the mounting base 30; and a drive cylinder 50, which is connected to the mounting base 30 via a transmission mechanism. The drive cylinder 50 drives the mounting base 30 to rotate, causing the clamping cylinder 40 and the clamped workpiece to rotate and flip together. It is understood that this flipping mechanism is driven by the drive cylinder 50, i.e., pneumatically driven, which has lower procurement costs, lower maintenance requirements, and lower energy consumption compared to electrically driven manipulators. Furthermore, the flipping process achieved by pneumatic drive is smoother, reducing impact on the workpiece and further improving the uniformity of coating quality and the safety of the workpiece.

[0036] The mounting base 30 is connected to the clamping arm 10 via a bearing, allowing the mounting base 30 to rotate freely.

[0037] A spraying device includes a flipping mechanism. Understandably, during workpiece spraying, this flipping mechanism enables automatic workpiece flipping, ensuring that all surfaces of the workpiece, including the top and bottom, receive uniform spraying treatment. This improves the comprehensiveness and consistency of the spraying coverage, reduces the need for manual operation, and increases production efficiency and product quality. Therefore, when this flipping mechanism is used in the spraying device, the drive cylinder 50 drives the clamping cylinder 40 to flip by 180°, meaning the workpiece is simply rotated and flipped. Of course, when the workpiece has multiple spraying surfaces, the parameters of the drive cylinder 50 can be set according to the specific shape of the workpiece surface to rotate the workpiece by a specific angle.

[0038] In some embodiments, the drive cylinder 50 is fixedly connected to the frame 1. Specifically, the drive cylinder 50 can be fixedly connected to the frame 1 via a mounting plate. Alternatively, the drive cylinder 50 can also be an electric cylinder, hydraulic cylinder, pneumatic cylinder, etc., preferably a pneumatic cylinder. The initial purchase cost of a pneumatic cylinder is generally lower than that of a hydraulic or electric system. The air source (compressed air) is relatively inexpensive and readily available. Furthermore, pneumatic systems have a simple structure, fewer components, are relatively easy to maintain and repair, do not have complex electrical systems, are less susceptible to electromagnetic interference, and do not require regular lubrication changes. Therefore, pneumatic cylinders are preferred.

[0039] In some embodiments, refer to Figure 1-3 The frame 1 is equipped with a drive rod 20 that is pulverizedly connected to the drive cylinder 50. The drive rod 20 has a first transmission part 201 at both ends, and the mounting base 30 has a second transmission part 301. The first transmission part 201 and the second transmission part 301 are pulverizedly connected via a transmission component 60. It can be understood that the first transmission part 201 at both ends of the drive rod 20 can synchronously drive the mounting base 30 located on both sides of the clamping arms 10 to rotate via the second transmission part 301 on the driving mounting base 30. This allows the clamping cylinder 40 to clamp the workpiece and simultaneously apply a flipping torque to both ends of the workpiece, ensuring the workpiece remains balanced during the flipping process, reducing vibration and offset during flipping, and improving the stability and safety of the workpiece during the flipping process.

[0040] In some embodiments, refer to Figure 3 The first transmission part 201 is a gear or pulley, the second transmission part 301 is a gear or pulley matched with the first transmission part 201, and the transmission component 60 is a belt or chain. It can be understood that when the first transmission part 201 and the second transmission part 301 are gears, the transmission component 60 is a chain, resulting in chain drive. Chain drive provides efficient power transmission, suitable for applications requiring high torque and high load, and can adapt to large center distance variations. Chain drive has a high transmission ratio and a long service life. When the first transmission part 201 and the second transmission part 301 are belts, the transmission component 60 is a belt, resulting in belt drive. Belt drive transmits power through the friction of the belt, suitable for applications requiring smooth operation, low noise, and small loads. It absorbs shock and vibration, is relatively simple to install and maintain, and is suitable for applications requiring speed changes and adjustments. Belt drive is generally more economical than chain drive and is suitable for small to medium power transmissions. Both of the above transmission methods drive the mounting base 30 to rotate via the drive rod 20, thereby achieving workpiece flipping and providing different transmission characteristics to adapt to different types of workpieces and application requirements.

[0041] In some embodiments, the output end of the clamping cylinder 40 is provided with a clamping head 401 or a clamping jaw. It is understood that the design of the clamping head 401 or clamping jaw can be adjusted according to the shape and size of the workpiece to ensure that the workpiece is subjected to uniform force during clamping, avoiding workpiece deformation or damage. The clamping head 401 is suitable for clamping workpieces with regular shapes, while the clamping jaw can adapt to workpieces with irregular shapes, providing greater flexibility.

[0042] Furthermore, when the output end of the clamping cylinder 40 is a clamping head 401, a buffer layer 4011 is provided on the side of the clamping head 401 used to clamp the workpiece. It is understood that the buffer layer 4011 protects the surface of the workpiece, preventing scratches, indentations, or other forms of damage caused by direct contact during clamping. Simultaneously, the buffer layer 4011 absorbs the impact force during clamping, ensuring that the clamping force is more evenly distributed on the workpiece surface, thus improving the clamping effect and workpiece safety.

[0043] Furthermore, the buffer layer 4011 is a rubber layer or a silicone layer.

[0044] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
