[0002] Flocking is a method of fixing short fibers vertically on a substrate coated with an adhesive. The principle of flocking is to use the physical property that like charges repel each other and opposite charges attract each other, so that the fluff carries a negative charge. When the object to be flocked is placed under zero potential or grounding conditions, the fluff is attracted by the plant body with different potential and accelerates vertically to the surface of the object to be flocked. Since the plant body is coated with adhesive, the fluff is vertically adhered to the plant body.

For those of ordinary skill in the art, the specific meanings of the above terms in the embodiments of the present utility model can be understood according to specific circumstances.

[0034] In an embodiment of the dipping and spin coating machine of the present utility model, please refer to Figures 1 to 3 . The dipping and spin coating machine is used to complete dipping and spin coating of workpieces on the same device, improving production efficiency. Specifically, the dipping and spin coating machine includes a dipping tank 100, a first motor 200, a rotating shaft 300, a rotating frame 400, a rotation driving assembly 500, and a mounting seat 600. Two groups of mounting seats 600 are respectively arranged at both ends of the dipping tank 100. The rotating shaft 300 is rotatably supported on the two mounting seats 600, and the first motor 200 is connected to the rotating shaft 300, and the first motor 200 can drive the rotating shaft 300 to rotate. Among them, the number of the rotating frames 400 is two groups, and they are respectively fixedly sleeved at both ends of the rotating shaft 300. The rotating frame 400 is provided with at least one connecting shaft 410, and one end of the connecting shaft 410 is provided with a holding portion 411. A clamping position 412 is formed by the two holding portions 411 corresponding to the two rotating frames 400, and the clamping position can fix the workpiece to be dipped. Each connecting shaft 300 is connected to a rotation driving assembly 500, and the rotation driving assembly 500 is used to drive the connecting shaft 410 to rotate, so that the workpiece clamped in the clamping position 412 rotates.

[0035] The rotating shaft 300 is rotatably supported on two mounting seats 600. Two sets of rotating frames 400 are respectively fixedly sleeved at both ends of the rotating shaft 300. Since the first motor 200 is connected to the rotating shaft 300, it drives the rotating shaft 300 and drives the rotating frames 400 to rotate together. And the clamping positions 412 formed by the corresponding holding parts 411 of the two rotating frames 400 can be used to clamp the workpieces to be dipped in glue. During the rotation of the rotating frames 400, the workpieces will be immersed in the dipping glue tank 100 to complete dipping in glue and then leave the dipping glue tank 100. In addition, the connecting shaft 410 on the rotating frame 400 is connected to the rotation driving assembly 500, and the rotation driving assembly 500 drives the connecting shaft 410 to rotate, so that the workpieces clamped in the clamping positions 412 rotate themselves to fling off the glue, flinging off the excess glue to ensure that a uniform glue layer can be formed on the surface of the workpieces. By adjusting the number of self-rotations of the workpieces, different amounts of glue on the surfaces of the workpieces are flung off, and thus glue layers with different thicknesses are formed on the surfaces of the workpieces. The thickness range of the glue layer is 0.05 - 0.3 mm, so as to meet different subsequent flocking requirements. The two processes of dipping in glue and flinging off glue of the workpieces are completed on one device, reducing the processing devices and saving the installation space; and the flung-off glue directly returns to the dipping glue tank 100, improving the production efficiency and reducing the processing cost of the glue.

[0036] Further, please refer to Figure 2 , the rotation driving assembly 500 includes a rotating sleeve 510, a second motor 520 and a chain transmission mechanism 530. The rotating sleeve 510 is rotatably sleeved on the rotating shaft 300, and the second motor 520 is connected to the rotating sleeve 510 for driving the rotating sleeve 510 to rotate. Specifically, a gear transmission assembly is provided between the second motor 520 and the rotating sleeve 510, and the power of the second motor 520 is transmitted by the gear transmission assembly to make the rotating sleeve 510 rotate. The chain transmission mechanism 530 is connected to the connecting shaft 410 and the rotating sleeve 510. Specifically, since the chain transmission mechanism 530 is connected to the connecting shaft 410 and the rotating sleeve 510 (the chain of the chain transmission mechanism is not marked in the figure), when the second motor 520 drives the rotating sleeve 510 to rotate, it will drive the chain transmission mechanism 530 to rotate, causing the connecting shaft 410 to rotate itself.

[0037] Further, please refer to Figure 1 , the rotating frame 400 extends with a plurality of extending parts 420, each extending part 420 is provided with a connecting shaft 410, and a chain transmission mechanism 530 is connected between each connecting shaft 410 and the rotating sleeve 510. Specifically, a plurality of extending parts 420 are provided, and each extending part 420 is provided with a connecting shaft 410, which can clamp and hold a plurality of workpieces to be dipped in glue, improving the production efficiency. A chain transmission mechanism 530 is connected between each connecting shaft 410 and the rotating sleeve 510. Preferably, one chain transmission mechanism 530 can be directly connected to two connecting shafts 410, reducing the connecting parts and making the structure more compact.

[0038] Further, this embodiment is for the dipping processing of workpieces that can be stretched, such as springs, etc. Specifically, please refer toFigure 2 , the rotating frame 400 is slidably sleeved on the rotating shaft 300; the rotating sleeve 510 includes a first rotating sleeve 511 and a second rotating sleeve 512, and the ends of the first rotating sleeve 511 and the second rotating sleeve 512 are provided with engaging clutch teeth. The second rotating sleeve 512 is slidably sleeved on the rotating shaft 300, and the second rotating sleeve 512 is only rotatably connected to the rotating frame 400. When the second rotating sleeve 512 moves, the rotating frame 400 moves together. The second motor 520 is connected to the first rotating sleeve 511, and the chain transmission mechanism 530 is connected to the second rotating sleeve 512. A connecting plate 710 is rotatably sleeved on the second rotating sleeve 512, and the connecting plate 710 is connected to a flat pushing member 700 for pushing the second rotating sleeve 512 and the rotating frame 400 to slide on the rotating shaft 300. Specifically, the flat pushing member 700 pushes the second rotating sleeve 512 and the rotating frame 400 to slide on the rotating shaft 300, and can push the two rotating frames 400 closer to each other, so that the distance of the clamping position 412 formed by the two holding portions 411 is reduced, facilitating the clamping of the workpiece. During dipping, the flat pushing member 700 pushes the second rotating sleeve 512 to translate towards one end of the first rotating sleeve 511, so that the second rotating sleeve 512 engages with the first rotating sleeve, and at the same time, the workpiece to be dipped is stretched and unfolded. Then, the first motor 200 drives the rotating frame 400 to rotate to complete dipping.

[0039] Further, please refer to Figure 2 , a limiting sleeve 430 extends from the side of the rotating frame 400 away from the second rotating sleeve 512. The limiting sleeve 430 is provided with a limiting chute 431, and the rotating shaft 300 is provided with a limiting rod 310 extending out of the limiting chute 431. Specifically, the rotating shaft 300 is provided with a limiting rod 310 extending out of the limiting chute 431, so that the rotating frame 400 rotates as the rotating shaft 300 rotates. The limiting chute 431 defines the sliding stroke of the flat pushing member 700 for pushing the rotating frame 400 to slide on the rotating shaft 300.

[0040] Further, please refer to Figure 3 , a connecting sleeve 440 is provided on the other side of the rotating frame 400. The connecting sleeve 440 is fixedly connected to the rotating frame 400, and the second rotating sleeve 512 is rotatably sleeved on the connecting sleeve 440. Specifically, the second rotating sleeve 512 is rotatably sleeved on the connecting sleeve 440, so that the chain transmission mechanism 530 is also arranged on the connecting sleeve 440. Furthermore, when the second motor 520 drives the rotating sleeve 510 to rotate on the connecting sleeve 440 and drives the connecting shaft 410 to rotate, the rotating frame 400 can remain stable and motionless, ensuring that the workpiece will not be dipped again during spin coating.

[0041] Further, the flat pushing member 700 is a cylinder arranged on the mounting seat 600. Specifically, the use of a cylinder for driving has a simple structure and a simple control program that is easy to operate.

[0042] Further, please refer to Figure 1, lifting mechanisms 800 are also provided at both ends of the dipping tank 100, and the mounting seat 600 is disposed on the lifting mechanisms 800. Specifically, the lifting mechanisms 800 can drive the mounting seat 600 to move up and down away from or close to the dipping tank 100. After the dipping process is completed, the workpiece clamped on the rotating frame 400 can be moved away from the dipping tank 100 through the lifting mechanisms 800, and then the workpiece can be subjected to the glue throwing operation at the same time, further improving the production efficiency.

[0043] For further information, please refer to Figure 1 A baffle 450 is also provided between the two rotating frames 400, and the baffle 450 is located on one side of the clamping position 412. Specifically, the baffle 450 can catch the excess glue thrown out by the workpiece during rotation to prevent the glue from splashing out of the glue dipping tank. In addition, the caught glue can fall from the baffle 450 into the glue dipping tank 100, so that the thrown glue can be directly recycled and reused to avoid waste.

[0044] For further information, please refer to Figure 1 The holding portion 411 is provided with a hook. The end of the workpiece is fixed by the hook.

[0045] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
