TECHNICAL FIELD

[0001] The present application relates to the technical field of vacuum coating, in particular to a coating equipment capable of continuous vacuum coating. BACKGROUND

[0002] The vacuum coating equipment is an industrial device that forms a functional film on the surface of a substrate (such as glass, metal, plastic, etc.) by physical vapor deposition (PVD) or chemical vapor deposition (CVD) technology under a high vacuum environment. The core process includes evaporation coating, sputtering coating, and ion plating, etc.

[0003] However, the traditional single-chamber or batch-type vacuum coating equipment cannot be continuously operated because it needs to break the vacuum to take and place the substrate for each batch of coating, which consumes time and energy to re-evacuate, making it difficult to improve the production rhythm.

[0023] Please see Figures 1 to 12 One embodiment of this application provides a continuous coating apparatus for vacuum coating of workpieces in consecutive batches.

[0024] Combination Figures 1 to 5 As shown, in this embodiment, the continuous coating equipment includes: Several coating chambers 1 are connected in sequence. Each coating chamber 1 has openings 101 on both sides for the coating rack 4 to pass through. Adjacent coating chambers 1 are separated by partition doors 103. The coating chamber 1 at the end of the continuous coating equipment has a door 102 on its outside for closing the openings 101. A conveying mechanism 110 is provided at the bottom of the inner cavity of each coating chamber 1. The conveying mechanism 110 is connected to the openings 101 on both sides of the coating chamber 1. A rotating mechanism 120 is provided at the bottom of each coating chamber 1.

At least one transfer station 2 is connected to the coating chamber 1 at the end of the continuous coating equipment. The transfer station 2 is provided with a transfer mechanism 210 for transferring the coating frame 4. The transfer mechanism 210 is aligned with the conveying mechanism 110 of the coating chamber 1. The transfer mechanism 210 and each conveying mechanism 110 form a transfer path for transferring the coating frame 4. Carrier plate 3 is used to support coating rack 4. Carrier plate 3 is movably mounted on the transmission mechanism 210 or conveying mechanism 110 of continuous coating equipment.

[0025] Among them, combined Figure 1 and Figure 2 As shown, in this embodiment, there are two coating chambers 1. In other embodiments, the number of coating chambers 1 can be increased according to production needs, and the structure of each coating chamber 1 can be configured according to the scheme of this application.

[0026] In this embodiment, two transfer stations 2 are configured, located at opposite ends of the continuous coating equipment, namely the upper and lower ends, to facilitate the loading and unloading of the coating rack 4.

[0027] In this embodiment, the carrier plate 3 adopts a flat plate structure to stably support the coating rack 4. Furthermore, combined with... Figure 11 As shown, a central hole 301 is provided in the middle of the carrier plate 3. The central hole 301 allows the top of the rotating mechanism 120 to pass through and abut against the coating frame 4, so as to drive the coating frame 4 to rotate and perform uniform vacuum coating on the workpiece of the coating frame 4.

[0028] It should be noted that the coating rack 4 in the accompanying drawings is only for illustrating the technical solution of this application. It does not show the hanger and workpiece installed on the coating rack 4. Those skilled in the art can set the coating rack 4 according to actual needs.

The internal gear 1151 of the first gear rod 1131 is connected to the internal gear 1151 of the second gear rod 1132 via a first chain 1141. The internal gear 1151 of the third gear rod 1133 is connected to the internal gear 1151 of the fourth gear rod 1134 via a second chain 1142. The external gear 1152 of the second gear rod 1132 is connected to the external gear 1152 of the third gear rod 1133 via a third chain 1143.

[0032] By staggering the first chain 1141, the second chain 1142, and the third chain 1143, more space can be reserved on the side of the transmission assembly to accommodate the installation of other functional components.

[0033] To facilitate adjustment of the tension of each chain, in this embodiment, the transmission assembly further includes a first adjusting rod 1135, a second adjusting rod 1136, and a third adjusting rod 1137 movably disposed on the bracket 111.

[0036] Combination Figure 6 , Figure 7 and Figure 9 As shown, in order to prevent the carrier plate 3 from slipping, a positioning edge 303 is provided on one side of the carrier plate 3 protruding downward. The first gear rod 1131, the second gear rod 1132, the third gear rod 1133 and the fourth gear rod 1134 are all provided with a groove 1162 that cooperates with the positioning edge 303.

[0037] Since the coating rack 4 is quite heavy when fully loaded, in order to avoid the coating rack 4 having a significant impact on the conveying mechanism 110 when placed on the carrier plate 3, in this embodiment, the bracket 111 is fixedly provided with a buffer pad 117 for abutting against the carrier plate 3. Specifically, a damping shock-absorbing pad may be provided at the top of the buffer pad 117 to reduce the pressure of the carrier plate 3.

[0041] Specifically, the support plate 121 can engage with the bottom of the coating frame 4 to drive the coating frame 4 to rotate. The engagement method can be implemented using existing technology, and this application does not provide special explanation or limitation.

[0042] In this embodiment, the lifting drive mechanism 124 is a telescopic cylinder, and the lifting rod 125 is drivenly connected to the telescopic cylinder to control the lifting and lowering of the movable plate 126. In other embodiments, the lifting drive mechanism 124 may also be a motor, and the lifting rod 125 may be a lead screw, which is drivenly connected to the motor and meshes with the movable plate 126. The rotation of the lead screw drives the movable plate 126 to lift and lower.

The transmission component 212 carries and moves the carrier plate 3.

[0046] The transmission component 212 can be connected to a gear chain similar to the transmission mechanism 110 of this application, or it can be connected to a transmission structure such as a belt and a rotating wheel, or a screw and a threaded sleeve.

[0047] Combination Figure 12 As shown, in order to stop the movement of the carrier plate 3 with the coating rack 4 in place, the transfer table 2 can be equipped with a positioning sensor 221. The positioning sensor 221 cooperates with the positioning block 302 of the carrier plate 3 to realize automatic stop control of the transfer drive mechanism 211.

[0048] To prevent foreign objects from falling or accidental contact by personnel, a shield 222 is provided on the outside of the transmission mechanism 210.

[0049] In this embodiment, the transmission drive mechanism 211 may be a servo motor. In other embodiments, the transmission drive mechanism 211 may also be other actuators that can provide driving force, such as rotary cylinders.
