Description

Technical Field

[0001] This utility model relates to the field of vacuum coating technology, and in particular to a vacuum coating machine hanger transfer device. Background Technology

[0002] A vacuum coating machine is a key piece of equipment that deposits thin films on the surface of a substrate in a vacuum environment using physical or chemical methods. It is widely used in optics, electronics, semiconductors, automotive, and decorative materials industries. Its core processes include evaporation coating, sputtering coating (such as magnetron sputtering and ion beam sputtering), and molecular beam epitaxy. During the use of a vacuum coating machine, the product to be coated needs to be placed on a rotating frame. The rotating frame currently used includes a turntable, a base coaxially fixed to the turntable via a connecting rod, and several hanging rods arranged around the circumference of the turntable. Each hanging rod has hooks around its circumference for suspending the product to be coated. The turntable and base have corresponding insertion holes, and a tray is fixed to the lower end of the base. The product to be coated is suspended on the hooks. The operator holds the hanging rod at an angle, passes the upper end of the rod through the insertion hole of the turntable, and then rotates the rod to a vertical position before lowering it so that it passes through the insertion hole of the base and contacts the tray. The vacuum coating machine is equipped with a drive motor to rotate the turntable.

[0003] Vacuum coating machines are equipped with a rod transfer device for placing the rods. After coating, operators need to remove the rods and place them on the rod transfer device, which then moves them to the inspection station. After inspecting the coated products on the rods, subsequent packaging operations are performed. However, currently used rod transfer devices include transfer carts with fixed platforms. These platforms have several rod placement stations around their circumference. During rod transfer, operators need to manually move the rods to the placement stations on the platform, requiring frequent movement and resulting in low efficiency. Utility Model Content

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a vacuum coating machine hanging rod transfer device that can stably place the hanging rod, facilitate manual handling, and has high efficiency.

[0022] The present invention will now be described in further detail with reference to the accompanying drawings. In the description of the present invention, it should be understood that directional terms such as "upper," "lower," "top," and "bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used only for the convenience of describing the present invention and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of the present invention. The directional terms "inner" and "outer" refer to the inner and outer contours relative to the outline of each component itself.

[0023] like Figure 1-7 As shown, a vacuum coating machine hanging rod transfer device includes a transfer seat 1, a handle 2 fixedly installed on one side of the transfer seat, several wheel frames fixedly installed below the transfer seat, and rollers 3 rotatably installed on the wheel frames; several vertically arranged support columns 4 are fixedly installed above the transfer seat, and the upper ends of the several support columns are fixedly connected to a top seat 5.

[0024] It also includes several base supports 6 and the same number of hanging brackets 7 as the base supports. The hanging brackets correspond one-to-one with the base supports and are spaced apart above the base supports. Limiting cylinders 8 are fixedly installed on the base supports. The lower end of the hanging rod 9 can be inserted into the limiting cylinder. The hanging bracket has a hanging groove 10. The upper end of the hanging rod has hanging shafts 11 on both sides that are connected to the hanging groove. It also includes a drive structure for driving the base supports and hanging brackets to move synchronously.

[0025] After coating is completed, the vacuum coating machine is turned on. The operator removes the hanging rod, inserts the upper end of the hanging rod into the hanging slot, and inserts the lower end of the hanging rod into the limiting cylinder. Then, the drive structure rotates the base and the hanging bracket at a certain angle, aligning the next hanging rod placement station with the vacuum coating machine. This allows the operator to place the hanging rod on the hanging rod transfer device. After placement, the operator holds the handle and pushes the hanging rod transfer device to the inspection station. The rollers facilitate the movement of the hanging rod transfer device. The corresponding base and hanging bracket form the hanging rod placement station.

[0026] In implementation, the drive structure includes four vertically arranged drive shafts 12. The drive shafts are connected to the transfer seat and the top seat through bearings. Upper sprockets 13 and lower sprockets 14 are fixedly installed on the drive shafts. The upper sprockets are located above the top seat and the four upper sprockets are connected by an upper chain 15. The lower sprockets are located above the transfer seat and the four lower sprockets are connected by a lower chain 16. The lower end of one of the drive shafts passes through the transfer seat and is fixedly connected to the output shaft of a servo motor. The servo motor is fixedly installed below the transfer seat.

[0027] The inner side of the base is fixedly connected to the lower chain; a hanging plate 17 is fixedly installed on the upper end of the bracket, and the inner side of the scraper is fixedly connected to the upper chain.

[0028] In this way, the servo motor drives one of the drive shafts to rotate, and under the transmission action of the upper and lower chains, the four drive shafts rotate synchronously. The synchronous rotation of the upper and lower chains enables the adjustment of the position of the hanging rod placement station, facilitating manual placement of the hanging rod. Specifically, a power supply and motor controller are installed below the transfer seat, which are used to power the servo motor and control its operation, for use with existing equipment.

[0029] In practice, a lower guide rail 18 is fixedly installed on the transfer seat, and a number of lower slide blocks 19, the same as the number of base supports, slide on the lower guide rail. The base supports and the lower slide blocks correspond one-to-one and are fixedly connected. This facilitates guiding the movement of the base supports.

[0030] In practice, an upper guide rail 20 is fixedly installed on the top seat, and upper sliders 21, the same number as the scrapers, slide on the upper guide rail. The scrapers and upper sliders correspond one-to-one and are fixedly connected. This facilitates guiding the movement of the hanger.

[0031] In implementation, the lower and upper guide rails are respectively provided with protruding outer ribs 22 and inner ribs on both sides, and the lower and upper sliders are provided with sliding grooves that slide with the outer and inner ribs. This makes the connection between the lower slider and the lower guide rail, and the connection between the upper slider and the upper guide rail, more stable and prevents them from disengaging. The lower and upper guide rails have the same structure, and the lower and upper sliders have the same structure.

[0032] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
