Technical Field

[0001] The present invention relates to the technical field of coating processing, and in particular to a roll-to-roll vacuum coating device. Background Art

[0002] Existing coating equipment usually has multiple coating nozzles inside the coating equipment for spraying coating materials onto the surface of the workpiece to be coated. In this way, the coating workpieces need to be effectively arranged to ensure the integrity of the coating.

[0003] Therefore, we propose a winding vacuum coating device arranged around the workpiece to be coated, which can effectively ensure the integrity of the coating. Summary of the invention

[0004] In view of the defects in the prior art, the present invention provides a roll-to-roll vacuum coating device to ensure the integrity of the coating.

[0005] The present invention provides a roll-to-roll vacuum coating equipment, comprising: a coating machine main body, which is used to produce spray coating materials; and a winding group tube, which is arranged on the coating machine main body at least in one place, and the winding group tube can surround the workpiece to be coated; the winding group tube is connected to the coating machine main body, and sprays the outer film produced by the coating machine main body onto the surface of the workpiece to be coated.

[0006] Furthermore, it also includes: a positioning member, which is provided in multiple locations and evenly distributed in the coating machine body, and is used to place the workpiece to be coated. In actual use, the essence of the positioning member is similar to the function of a workpiece fixture, which is to meet the above-mentioned workpiece to be coated, so that it can be effectively placed to avoid the occurrence of sideways and other phenomena during the processing process.

[0007] Furthermore, the positioning member includes a positioning platform and a positioning bracket; the positioning platform is installed in the coating machine body, and the positioning bracket is installed on the positioning platform. In actual use, this design is to further ensure the overall stability.

[0008] Furthermore, the positioning member also includes a rotating base and a rotating motor, the rotating base is rotatably mounted on the positioning platform, and the rotating motor drives the rotating base to rotate, and the positioning bracket is fixedly mounted on the rotating base. In actual use, the purpose of this design is to further fix and shape the above-mentioned winding group tube to facilitate spraying, and through rotation, multi-directional spraying is achieved all around.

[0009] Furthermore, the winding tube group includes an outer flexible tube, an inner through tube and a spring support tube; the spring support tube is installed outside the inner through tube, and the spring support tube is located inside the outer flexible tube; the inner through tube is connected to the coating machine body. In actual use, the purpose of this design is to facilitate the bending of the winding tube group to any area. Of course, in the actual operation process, it is mainly close to the workpiece to be sprayed, so that the coating integrity of the coated workpiece after processing can be better; wherein the outer flexible tube is made of easily deformable materials, including but not limited to metal or non-metallic materials; and the spring support tube also utilizes its deformable bending and stretching characteristics. Of course, in actual use, it does not need to be stretched, only bent. In this way, on the one hand, it can achieve effective support for the outer flexible tube, and at the same time, it can also achieve effective limitation of the inner through tube, which greatly ensures that the spraying material generated by the coating machine body can be transmitted and transported through the inner through tube.

[0010] Furthermore, the winding tube assembly also includes a three-way nozzle, which is installed at the inner tube, and the third nozzle of the three-way nozzle extends outward and passes through the outer flexible tube. In actual use, this design is provided at multiple locations on the winding tube assembly, and is provided one by one along its axial direction; at the same time, this design effectively ensures that the spraying material is sprayed outward to realize the spraying process.

[0011] Furthermore, the winding pipe assembly also includes a rotating spray head, which is rotatably installed at the third nozzle of the three-way nozzle; the rotating spray head includes a rotating ball sleeve and a ball tube, the rotating ball sleeve is fixedly installed in the three-way nozzle, and the ball tube is rotatably installed in the rotating ball sleeve. In the actual design, the purpose of this design is to facilitate rotary spraying, so that it can be used together with the above-mentioned rotating base, so that the traditional spraying method has been greatly improved. The traditional overall top-down spraying and outer wall rotary spraying method have been effectively replaced by the near-winding spraying in the application, which not only improves the spraying efficiency, but also greatly improves the integrity after spraying, so that the completeness rate of the finished product can be effectively guaranteed.

[0012] Furthermore, the rotary nozzle also includes a mounting sleeve and an electromagnetic point block; the mounting sleeve is detachably mounted at the third nozzle of the three-way nozzle and close to the rotating ball sleeve; the mounting sleeve is also provided with a mounting slot, and the mounting slots are provided in multiple locations and are evenly distributed along the radial direction of the mounting sleeve; there are multiple electromagnetic point blocks, and they are installed one by one in the mounting slots; the electromagnetic point block is electrically connected to an external power supply; the ball tube is magnetically connected to the electromagnetic point block, and the rotating ball sleeve and the mounting sleeve are both made of non-metallic materials; any one of the electromagnetic point blocks is electrically connected to an external power supply separately. In actual application, the purpose of this design is to realize the steering control of the above-mentioned ball tube. In actual operation, through the power supply status of the electromagnetic point block, for example, when the above-mentioned ball tube needs to rotate, the electromagnetic point blocks can be energized in turn, and one on and one off, that is, two adjacent electromagnetic point blocks, after one is energized, when the next one needs to be energized, the previously energized electromagnetic point block will be de-energized; and when the ball tube needs to be turned, the electromagnetic point block in the opposite position of its rotation direction can be energized.

[0013] Furthermore, the winding tube assembly also includes a pressure jacking pipe and a slider piston; the pressure jacking pipe is installed on the inner tube and communicates with the inner tube, and the pressure jacking pipe is located at one end of the inner tube, and in the direction away from the coating machine body, the slider piston is slidably installed in the pressure jacking pipe. In actual use, the purpose of this design is to ensure the pressure and pressurize the fluid in the inner tube to avoid the reduction of the spraying pressure in the direction away from the coating machine body. The purpose of this design is to ensure the balance of pressure. The sliding piston realizes downward pressure through its own weight and realizes upward movement under the pressure of the spraying fluid. In this way, reciprocating motion can be realized. Of course, in order to further ensure that the slider piston realizes reciprocating motion, it is also possible to add a connecting reciprocating member, such as a connecting spring, and connect the two ends of the connecting spring to the slider piston and the pressure jacking pipe respectively. In this way, the reciprocating motion of the slider piston can be further realized.

[0014] Furthermore, the winding tube assembly also includes an inner sliding brush tube sleeve, the outer wall of which is fixedly installed in the pressure top tube, and the inner wall of the inner sliding brush tube abuts against the slider piston; the inner sliding brush tube includes an abutting sliding section and a cleaning section. In actual use, the purpose of this design is to clean the coating material on the surface of the slider piston, to ensure the cleanliness of the slider piston surface, and to prevent the slider piston surface from being scratched by the sprayed material.

[0015] It can be seen from the above technical solution that the roll-to-roll vacuum coating equipment provided by the present invention has the following beneficial effects:

[0016] (1) In actual use, the coating machine used in this design adopts the existing design, which reduces the huge internal improvement cost and greatly saves time cost;

[0017] (2) Moreover, the winding tube group design adopted is different from the traditional coating machine main body spraying design method. The original coating machine main body spraying scheme mostly adopts spraying along the inner wall of the coating machine main body. A plurality of spraying tubes are arranged around the inner wall, which is similar to the winding tube group; the spraying tube sprays the spraying material produced by the coating machine main body onto the surface of the workpiece to be coated. The working principle is the same as that of the present application, except that the present application is processed nearby and is arranged around the workpiece to be coated. Compared with the original spraying tube arrangement around the inner wall, the integrity of the spraying is better guaranteed;

[0018] (3) Moreover, the winding tube assembly in the present application can be bent, which makes it more convenient to coat the surfaces of workpieces to be coated on different cavity surfaces. This greatly improves the scope of application of the product, especially for workpiece surfaces that are difficult to spray, such as blind cavities and special-shaped cavities on different cavity surfaces, and further ensures the integrity of the work.
