Description

Technical Field

[0001] This utility model relates to the field of vacuum coating technology, specifically a high-pressure vacuum coating device. Background Technology

[0002] High-pressure vacuum deposition equipment is a device that performs thin film deposition in a high-vacuum environment. Its main working principle is to transfer materials from a target to a substrate using physical vapor deposition technology to form a thin film. High-pressure vacuum deposition equipment is widely used in electronics, optics, materials and other fields, and is applied in mobile phone casings, computer casings, and metal structural parts. High-pressure vacuum deposition equipment can achieve thin film deposition of various materials with high purity, high density and good surface properties.

[0003] A search revealed a Chinese utility model patent, CN218059187U, which discloses a high-pressure ion bombardment vacuum coating machine. The machine includes a main body with four feet fixedly connected to its lower end, symmetrically distributed. Two support columns are fixedly connected between the upper and lower inner walls of the main body, each with a sliding groove at its opposite end. Temperature control components are slidably installed within each groove. A motor mounting platform and a shaft mounting bracket are fixedly connected to the front end of the lower inner wall of the main body, with a feeding component fixedly connected to the upper end of the motor mounting platform. A coating device is fixedly connected to the middle of the lower inner wall of the main body, and a positioning plate is fixedly connected to the rear inner wall. A shell is detachably connected to the front end of the main body. This utility model achieves automated feeding and saves time and labor by incorporating the feeding component; it also achieves active temperature control and ensures coating quality by incorporating the temperature control component.

[0004] However, the device lacks the function of uniformly coating the workpiece. When in use, the workpiece is placed on the platform, and the angle of the workpiece cannot be changed during coating, resulting in different coating thicknesses on the workpiece and uneven coating. In addition, the device also lacks the function of workpiece positioning. When in use, the workpiece is placed directly on the platform and then coated. The workpiece cannot be fixed during coating, which makes it easy for the workpiece to move during coating and affects the coating quality. Utility Model Content

[0005] The purpose of this invention is to provide a high-pressure vacuum coating device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A high-pressure vacuum coating apparatus includes a coating machine body. A coating mechanism is fixedly installed on the inner top wall of the coating machine body. A first servo motor is fixedly installed at the center of the inner bottom wall of the coating machine body. A placement platform is fixedly installed on the rotating shaft of the first servo motor. A second servo motor is fixedly installed on one side of the placement platform. A bidirectional threaded rod is fixedly installed on the rotating shaft of the second servo motor. At least one pair of moving blocks are threadedly connected to the outer surface of the bidirectional threaded rod. A positioning rod is fixedly installed on the top of each moving block. A positioning pad for abutting the workpiece is fixedly installed on the opposite side of each pair of positioning rods.

[0008] Preferably, the bottom wall of the placement platform is provided with a sliding groove, the sliding groove is arranged along the extension direction of the bidirectional threaded rod, and a slider is fixedly connected to the bottom of the moving block, the slider being slidably arranged in the sliding groove.

[0009] Preferably, a rotating ring is fixedly installed at the bottom of the placement platform, and a rotating groove is provided on the bottom wall of the coating machine body near the first servo motor. The rotating ring is rotatably disposed inside the rotating groove.

[0010] Preferably, the top of the placement platform is provided with a movable hole, which is arranged along the extension direction of the bidirectional threaded rod.

[0011] Preferably, a heating plate is fixedly installed on the inner side wall of the coating machine body.

[0013] Preferably, support legs are fixedly installed at the four corners of the bottom of the coating machine body, and anti-slip pads are fixedly connected to the bottom of the support legs.

[0014] Preferably, the front of the coating machine body is hinged with an organic door.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] This high-pressure vacuum coating device, through the arrangement of a first servo motor, a rotating ring, and a rotating block, activates the first servo motor when coating a workpiece placed on a platform. The operation of the first servo motor drives the platform to rotate, which in turn drives the rotating ring to rotate within a rotating groove. The rotation of the rotating ring within the rotating groove makes the platform rotate more smoothly, thereby achieving the effect of uniform coating of the workpiece on the platform.

[0017] This high-pressure vacuum coating device, through the arrangement of a second servo motor, a bidirectional threaded rod, and a positioning rod, allows the workpiece to be placed between the positioning rods during use. The second servo motor is then activated, driving the bidirectional threaded rod to rotate. The rotation of the bidirectional threaded rod, along with the sliding mechanism of a slider within a groove, causes several moving blocks to move relative to each other. The positioning pad clamps the workpiece, thus achieving the function of positioning the workpiece and preventing it from moving and affecting the coating quality. Attached Figure Description

[0025] Please see Figures 1-5 As shown, this utility model provides a technical solution:

[0026] A high-pressure vacuum coating apparatus includes a coating machine body 1, a coating mechanism 2 fixedly installed on the inner top wall of the coating machine body 1, a first servo motor 3 fixedly installed at the center of the inner bottom wall of the coating machine body 1, a placement platform 4 fixedly installed on the rotating shaft of the first servo motor 3, a second servo motor 5 fixedly installed on one side of the placement platform 4, a bidirectional threaded rod 6 fixedly installed on the rotating shaft of the second servo motor 5, at least one pair of moving blocks 7 threadedly connected to the outer surface of the bidirectional threaded rod 6, a positioning rod 8 fixedly installed on the top of each moving block 7, and a positioning pad 9 for abutting the workpiece fixedly installed on the opposite side of each pair of positioning rods 8.

[0027] Specifically, the coating machine body 1 and the coating mechanism 2 coat the workpiece on the placement platform 4. During coating, the first servo motor 3 is started, which drives the placement platform 4 to rotate. The rotation of the placement platform 4 drives the rotating ring 12 to rotate in the rotating groove 13. The rotation of the rotating ring 12 in the rotating groove 13 makes the rotation of the placement platform 4 more stable, thereby achieving the effect of uniform coating of the workpiece on the placement platform 4. Before coating, the workpiece is placed between the placement positioning rods 8, and the second servo motor 5 is started. The second servo motor 5 drives the bidirectional threaded rod 6 to rotate. The rotation of the bidirectional threaded rod 6 is caused by the sliding block 10 sliding in the sliding groove 11, which causes several moving blocks 7 to move relative to each other. The positioning pad 9 is used to clamp the workpiece, thereby achieving the effect of positioning the workpiece and preventing the workpiece from moving and affecting the coating quality.

[0028] In this embodiment, preferably, the bottom of the movable block 7 is fixedly connected to the slider 10, and the bottom wall of the placement platform is provided with a groove 11. The groove 11 is arranged along the extension direction of the bidirectional threaded rod 6. The bottom of the movable block 7 is fixedly connected to the slider 10, and the slider 10 is slidably arranged in the groove 11.

[0029] Specifically, by setting the slider 10 to slide within the groove 11, the moving block 7 moves more smoothly when the bidirectional threaded rod 6 rotates.

[0030] In this embodiment, preferably, a rotating ring 12 is fixedly installed at the bottom of the placement platform 4, and a rotating groove 13 is opened around the bottom wall of the coating machine body 1 near the first servo motor 3, and the rotating ring 12 is rotatably disposed inside the rotating groove 13.

[0031] Specifically, by rotating the rotating ring 12 within the rotating groove 13, the stability of the placement platform 4 is maintained when the placement platform 4 rotates.

[0032] In this embodiment, preferably, the top of the placement platform 4 is provided with an movable hole 14, which is arranged along the extension direction of the bidirectional threaded rod 6.

[0033] Specifically, the positioning rod 8 can be moved on the placement platform 4 by setting the movable hole 14.

[0034] In this embodiment, preferably, a heating plate 16 is fixedly installed on the inner side wall of the coating machine body 1.

[0035] Specifically, it allows users to place workpieces on the placement platform 4 and heat the inside of the coating machine body 1 through the heating plate 16.

[0036] In this embodiment, preferably, a counterweight 15 is fixedly installed on the side of the platform 4 away from the second servo motor 5.

[0037] Specifically, the counterweight 15 makes the platform 4 more stable when it rotates.

[0038] In this embodiment, preferably, support legs 18 are fixedly installed at the four corners of the bottom of the coating machine body 1, and anti-slip pads 19 are fixedly connected to the bottom of the support legs 18.

[0039] Specifically, the device is supported by the support leg 18, and the device is prevented from sliding by the anti-slip pad 19.

[0040] In this embodiment, preferably, the front of the coating machine body 1 is hinged to an organic door 17.

[0041] Specifically, the coating machine body 1 can be opened through the machine door 17.

[0042] In this embodiment, a high-pressure vacuum coating apparatus is used such that the workpiece to be coated is placed in the middle of the positioning rod 8 on the placement platform 4. Then, the second servo motor 5 is started, which drives the bidirectional threaded rod 6 to rotate. The rotation of the bidirectional threaded rod 6 is caused by the sliding block 10 sliding in the slide groove 11, which causes several moving blocks 7 to move relative to each other. The positioning pad 9 clamps the workpiece, thereby achieving the function of positioning the workpiece and preventing the workpiece from moving and affecting the coating quality. When coating the workpiece placed on the placement platform 4, the first servo motor 3 is started, which drives the placement platform 4 to rotate. The rotation of the placement platform 4 causes the rotating ring 12 to rotate in the rotating groove 13. The rotation of the rotating ring 12 in the rotating groove 13 makes the rotation of the placement platform 4 more stable, thereby achieving the function of uniform coating of the workpiece on the placement platform 4.
