Description

Technical Field

[0002] In modern industrial production, flocking technology is a commonly used surface treatment technology and is widely used in various fields, especially in the production process of automotive parts, electronic components, toys and decorations. Flocking is a technology that electrostatically adsorbs short fibers (usually nylon or polyester fibers) on the surface of an object to form a soft and delicate suede effect on the surface of the object, improving the appearance and touch of the product.

[0003] Existing flocking devices often encounter problems with clamping and positioning when flocking workpieces with irregular curved surfaces. Due to the complex and changeable shapes of irregular curved surfaces, traditional clamps are often unable to effectively and stably clamp such workpieces, resulting in the workpieces easily moving, rotating or tilting during the flocking process, thereby affecting the uniformity and quality of the flocking. In addition, unstable clamping may also cause damage to the workpiece and reduce the product yield. Utility Model Content

In addition, unstable clamping may also cause damage to the workpiece, reducing the yield rate of the product.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for uniform flocking of irregular surfaces, comprising a flocking box, a shell fixedly installed on the top of the flocking box, a processing chamber fixedly installed at the bottom of the shell, three placement plates are arranged at the top of the processing chamber, four clamps are arranged on the inner side of the placement plates, grooves are provided at the four corners of the placement plates, a movable rod is slidably connected to the inside of the groove, one side of the movable rod passes through the outside of the placement plate and is fixedly connected to the clamp, one side of the top and bottom of the clamp is fixedly connected with a flexible limit strip, a micro cylinder is fixedly installed on one side of the groove, and the output end of one side of the micro cylinder is fixedly connected to the movable rod.

[0006] Compared with the prior art, the beneficial effects of the utility model are:

[0019] Working principle: First, place the irregular curved workpiece to be flocked on the inner circular area of ​​the placement plate 8. After the micro cylinder 13 receives the clamping signal, it drives the movable rod 12 to slide in the groove 11 through the output end. The sliding of the movable rod 12 drives the clamping plate 10 to move toward the workpiece. During the movement of the clamping plate 10, the flexible limit strip 19 thereon first contacts the surface of the workpiece to play a role in buffering and positioning. As the clamping plate 10 continues to move, the workpiece is stably clamped between the four clamping plates 10. During the clamping process, the slider 15 in the slide groove 14 slides with the movement of the movable rod 12. At the same time, the slider 15 slides on the support rod 16 and is affected by the elastic force of the buffer spring 17 and the buffer spring 2 18. This design makes the clamping plate 10 more stable when clamping the workpiece, reduces the impact and damage to the workpiece, and improves the stability and reliability of clamping. When the workpiece is stably clamped, the frequency conversion motor starts to work, and the output end of the frequency conversion motor drives the rotating shaft 9 to rotate, thereby The placing plate 8 and the workpiece are driven to rotate. The rotating workpiece makes all parts of its surface evenly exposed to the flocking environment. At the same time, this rotational motion also helps to evenly distribute the flocking material on the surface of the workpiece. The fan 5 is started in the chassis 4 to generate a stable airflow. The airflow enters the processing chamber 3 through the nozzle 6. In the processing chamber 3, the airflow passes through the dispersion effect of the dispersion net 7 to form a uniform airflow field. This airflow field helps to evenly distribute the flocking material on the surface of the workpiece. Under the carrying of the airflow, the flocking material is ejected from the nozzle 6 and evenly covers the rotating workpiece surface. Due to the irregularity of the workpiece surface, the flocking material forms a uniform and delicate suede effect on the workpiece surface. When the flocking process is completed, the frequency conversion motor stops working, the workpiece stops rotating, and the micro cylinder 13 receives the release signal and drives the movable rod 12 to slide in the opposite direction, so that the clamping plate 10 releases the workpiece. The operator can easily take out the workpiece that has been flocked and proceed to the next step of processing or detection.

[0020] To sum up: the irregular surface uniform flocking device, by arranging the clamping plate 10 driven by the micro cylinder 13 at the four corners of the placement plate 8, and supplemented by the flexible limit strip 19, can realize the efficient clamping of irregular curved surface workpieces. The rapid response and precise control of the micro cylinder 13 ensure the uniformity and adjustability of the clamping force, and the flexible limit strip 19 effectively prevents the workpiece from being damaged during the clamping process. The combined design of the slide groove 14, the slider 15, the buffer spring 17 and the buffer spring 2 18 provides additional stability and buffering protection for the clamping system. This design not only further reduces the impact on the workpiece during the clamping process, but also significantly improves the stability and reliability of the clamping, and ensures the stability of the workpiece position during the flocking process. The placement plate 8 is connected to the variable frequency motor through the rotating shaft 9, so that the workpiece can rotate during the flocking process. This design is particularly suitable for the flocking of irregular curved surface workpieces, because through the rotation of the workpiece, the flocking material can be ensured to be evenly distributed on the workpiece surface, thereby improving the uniformity and quality of the flocking.
