Description

Technical Field

[0001] The present application relates to the technical field of coating machines, and in particular to an evaporation source protection device for a vacuum coating machine. Background Art

[0002] With the continuous development of industrial technology, vacuum coating technology has been widely used in various industrial fields, such as electronics, optics, decoration and packaging industries. Vacuum coating machine is an important equipment for achieving high-quality thin film deposition. However, in actual application, the coating material processing and protection during the coating process have become key factors affecting the coating quality and efficiency.

[0003] Traditional coating machines have some problems in the processing of coating materials. For example, the coating materials are prone to sticking before extrusion, resulting in uneven coating and affecting the quality of the final product. In addition, during the processing of coating materials of different thicknesses and lengths, the equipment needs to be adjusted frequently, which increases the complexity and inconvenience of operation and reduces production efficiency.

[0004] Based on this, those skilled in the art have proposed a vacuum coating machine evaporation source protection device. Summary of the invention

[0005] One of the purposes of the present application is to provide an evaporation source protection device for a vacuum coating machine.

[0006] In order to achieve the above purpose, the technical solution adopted in the present application is: a vacuum coating machine evaporation source protection device, including a coating mechanism, a protection mechanism and a winding mechanism, the protection mechanism and the winding mechanism are respectively arranged on both sides of the coating mechanism, the coating mechanism includes two vertical plates, a bottom plate is fixedly connected between the bottoms of the two vertical plates, a top plate is fixedly connected between the tops of the two vertical plates, four sliding rods are symmetrically fixedly connected between the bottom plate and the top plate, the outer side of the sliding rod is slidably connected to the upper coating plate, and a lower limit is slidably connected between the outer sides of the sliding rod and below the upper coating plate A positioning plate, a heating plate is fixedly connected to the lower limit plate, a heater is fixedly connected to the bottom plate and located below the heating plate, the heater is connected to the heating plate, two spring columns are symmetrically fixedly connected to the bottom plate, the tops of the spring columns extend to the top of the lower limit plate, two sliding blocks are symmetrically fixedly connected to the lower limit plate, the sliding blocks are slidably connected to the corresponding spring columns, a cylinder is fixedly connected to the top of the top plate, the output end of the cylinder extends to the bottom of the top plate and is fixedly connected to the top of the upper film plate, and a plurality of control buttons are arranged on the bottom plate.

[0007] From the above, it can be known that the cylinder is used to drive the upper film-covering plate to descend and cooperate with the lower limit plate to achieve the protection of the evaporation source and the coating operation. The output end of the cylinder is fixedly connected to the top of the upper film-covering plate. When the cylinder is started, its output end moves downward, driving the upper film-covering plate to slide downward along the slide bar. Under the guidance of the slide bar, the upper film-covering plate moves downward smoothly and gradually approaches the lower limit plate. The lower limit plate is fixedly connected to the outside of the slide bar and is connected to the bottom plate through a spring column, and has a certain elasticity. When the upper film-covering plate descends to a certain position, the lower limit plate is limited by the sliding block and the spring column to ensure that a closed space is formed between the upper film-covering plate and the lower limit plate. The heating plate located on the lower limit plate is heated by a heater to provide the required temperature environment for the coating process.

[0008] Preferably, the protection mechanism includes a protection frame, which is configured as a U-shaped structure, the top of the protection frame is fixedly connected to an electric push rod, the output end of the electric push rod extends to the inside of the protection frame and is fixedly connected to a sliding frame, the inside of the sliding frame is rotatably connected to a first rotating roller, the inside of the protection frame is rotatably connected to a second rotating roller, one side of the protection frame is symmetrically fixedly connected to two connecting blocks, a third rotating roller is rotatably connected between the two connecting blocks, a fourth rotating roller is rotatably connected between the two connecting blocks and below the third rotating roller, the top of the protection frame and the two sides of the electric push rod are symmetrically threadedly connected to two adjusting screws, the bottoms of the adjusting screws are in contact with the top of the sliding frame, sliding grooves are provided on both sides of the protection frame, the roller cores of the first rotating rollers extend to the outside of the protection frame through the sliding grooves, the outside of the protection frame is fixedly connected to a first driving motor, the output end of the first driving motor is connected to the roller core of the first rotating roller, and fixed blocks are fixedly connected to the two sides of the protection frame, and the rotating connection on the fixed blocks A reciprocating screw is connected, and the reciprocating screw is threadedly connected to the corresponding connecting block, and two sliding rods are symmetrically fixedly connected on the fixed block and located on the outer side of the reciprocating screw, and the sliding rods are slidably connected to the corresponding connecting block, and the outer side of the fixed block is rotatably connected to a first connecting pulley, and the first connecting pulley is meshed with the reciprocating screw through a bevel gear. The roller core of one end of the first rotating roller extends to the outer side of the protection frame and is fixedly connected to the second connecting pulley, and one end of the second rotating roller extends to the outer side of the corresponding protection frame and is fixedly connected to the third connecting pulley, and one side of the protection frame and located below the third connecting pulley are rotatably connected to a fourth connecting pulley and a fifth connecting pulley, and the outer sides of the first connecting pulley, the second connecting pulley, the third connecting pulley, the fourth connecting pulley and the fifth connecting pulley are all provided with teeth, and the outer sides of the second connecting pulley, the third connecting pulley, the fourth connecting pulley and the fifth connecting pulley are provided with a transmission belt for use, and the transmission belt is meshed with the outer side of the first connecting pulley.

[0009] Through the above technology, it can be known that the protection mechanism drives multiple connecting pulleys to rotate simultaneously through the transmission belt, so as to achieve the shaking of the coating material, prevent lamination before extrusion, and ensure the quality of subsequent coating. The specific working principle is as follows: the first driving motor drives the first rotating roller, and the first rotating roller transmits power to the transmission belt through the sliding groove. The transmission belt drives the second connecting pulley, the third connecting pulley, the fourth connecting pulley and the fifth connecting pulley to rotate synchronously, so that the first rotating roller, the second rotating roller, the third rotating roller and the fourth rotating roller can operate synchronously. The synchronous rotation of the transmission system is achieved by the meshing of the teeth of the transmission belt and each connecting pulley, so that the entire protection mechanism can operate stably. The first connecting pulley is meshed and connected with the reciprocating screw through the bevel gear, driving the reciprocating screw to rotate. The rotation of the reciprocating screw causes the connecting block to which it is threaded to move up and down along the sliding rod, thereby achieving reciprocating shaking of the coating material. The output end of the electric push rod is fixedly connected to the sliding frame, and the position of the sliding frame can be adjusted by adjusting the screw rod to adapt to coating materials of different thicknesses. During the whole process, the sliding frame drives the first rotating roller to rotate, ensuring that the coating material remains in a shaking state before entering the pressing state, so as to avoid the coating material from being attached before extrusion, thereby affecting the subsequent coating quality. Through this design, the protection mechanism can not only effectively protect the coating material, but also improve the stability and efficiency of the entire coating process through the synchronous operation of the transmission system and the precise control of the reciprocating screw.

The output end of the hydraulic cylinder is connected to the mounting frame, and the mounting frame is driven to slide up and down along the light rod through the telescopic action of the hydraulic cylinder, thereby realizing the adjustment of the position of the winding roller. The mounting frame is connected to a winding roller by a screw rotation, and the winding roller is used to wind the coating material. The winding roller is driven by a second drive motor, and the output end of the second drive motor is connected through a transmission wheel and a drive belt transmission to drive the winding roller to rotate, thereby realizing the winding of the coating material. The connection limit roller is arranged on the outside of the winding roller, which is used to limit the coating material during the winding process to ensure that the material will not deviate during the winding process. Through this design, the winding mechanism can stably and efficiently realize the winding operation of the coating material, and adjust the position of the winding roller through the hydraulic cylinder to meet the requirements of coating materials of different lengths.

[0012] Compared with the prior art, the beneficial effects of this application are:

[0013] 1. Through the coordinated work of the coating mechanism, the protection mechanism and the winding mechanism, the device can effectively prevent the laminating material from laminating before extrusion during the coating operation. Specifically, the transmission belt system in the protection mechanism drives multiple connecting pulleys to rotate synchronously to achieve the shaking of the laminating material, so that the laminating material maintains a proper separation state before entering the lamination, avoiding quality problems caused by laminating material laminating before extrusion.

[0026] One of the preferred embodiments of the present application is as follows: Figures 1 to 7 As shown, a vacuum coating machine evaporation source protection device comprises a coating mechanism 1, a protection mechanism 2 and a winding mechanism 3, wherein the protection mechanism 2 and the winding mechanism 3 are respectively arranged on both sides of the coating mechanism 1, and the coating mechanism 1 comprises two vertical plates 11, a bottom plate 12 is fixedly connected between the bottoms of the two vertical plates 11, a top plate 13 is fixedly connected between the tops of the two vertical plates 11, four sliding rods 14 are symmetrically fixedly connected between the bottom plate 12 and the top plate 13, an upper coating plate 15 is slidably connected to the outer side of the sliding rod 14, a lower limit plate 16 is slidably connected between the outer sides of the sliding rod 14 and below the upper coating plate 15, and a lower limit plate 16 is fixedly connected to the upper limit plate 16 There is a heating plate 17, and a heater 18 is fixedly connected to the bottom plate 12 and located below the heating plate 17, and the heater 18 is connected to the heating plate 17.
