Abstract

The present invention relates to the technical field of intelligent suspension and conveying systems, specifically a PVD vacuum coating intelligent suspension and conveying system, comprising a mounting frame, a driving mechanism installed at the bottom of the mounting frame, a suspension mechanism and a limiting mechanism installed on the fixing mechanism; a limiting mechanism is installed inside the fixing block, and the fixing block is slidably connected to the slide plate, so that the distance between the side plate and the column can be adjusted, which is beneficial to the suspension of larger workpieces, avoids the side plate blocking the coated parts, and frees up more space, which is beneficial for the suspension and transportation of different coated parts. After adjusting the outward expansion range of the slide plate, it needs to be fixed.

Description

Technical Field

[0001] The present invention relates to the technical field of intelligent suspension conveying systems, in particular to a PVD vacuum coating intelligent suspension conveying system. Background Art

[0002] PVD (physical vapor deposition) is an advanced surface treatment technology that transforms solid materials into gaseous atoms or molecules in a vacuum environment and deposits them onto the substrate to form a thin film, thereby imparting new properties or appearance to the material. PVD vacuum coating typically utilizes a circular guide rail for suspended conveying. The operating principle of the circular guide rail is based on rolling friction, with motion transmitted by rollers or balls on the slider rolling on the track.

[0003] However, at present, when vacuum coating some workpieces, the workpieces are hung on the hanging frame, and then the support frame for the hanging workpiece and the slider on the annular guide rail are fixed, and the hanging workpiece is driven by the annular guide rail to be transported to the door of the coating machine to complete the hanging and transportation of the long-distance coated workpiece. The support frame for the hanging workpiece is usually installed and fixed with a fixed frame and a moving block on the annular guide rail. The fixed frame and the moving block are directly welded together and are difficult to slide, and it is difficult to adjust the outward expansion range of the fixed frame. When the suspended workpiece is large, the workpiece will touch the fixed frame for the hanging workpiece, resulting in difficulty in fixing the fixed frame and the moving block, and difficulty in transporting the workpiece on the fixed frame; the transportation is achieved by the annular guide rail in combination with the slider and the roller. The rollers are located on both sides of the annular guide rail to provide support between the hangers and guide the moving block. The rollers and the annular guide rail are prone to wear due to long-term rolling. There is no lubrication mechanism on the moving block to lubricate the slide rail. The slide rail wears too quickly, and the unevenness of the slide rail can easily cause the coated part to shake during transportation, causing it to fall and damage the coated part.

When the coated parts are transported over a long distance, the coated parts are suspended on the suspension mechanism, and the suspension mechanism is fixed by the fixing mechanism.

DETAILED DESCRIPTION

[0032] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0033] like Figures 1-11 As shown, the PVD vacuum coating intelligent suspension conveying system of the present invention includes a mounting frame 1, a driving mechanism 2 installed at the bottom of the mounting frame 1, a conveying mechanism 3 installed on the driving mechanism 2, a fixing mechanism 4 installed on the conveying mechanism 3, and a suspension mechanism 5 and a limiting mechanism 7 installed on the fixing mechanism 4;

[0034] Specifically, the fixing mechanism 4 includes a fixing block 401, and a plurality of fixing blocks 401 are equidistantly installed on the conveying mechanism 3. Slide plates 402 are horizontally slidably connected to the plurality of fixing blocks 401. The bottom of the slide plate 402 is fixedly connected to a side plate 403, and the outer side of the side plate 403 is slidably connected to the shell 404. The bottom of the shell 404 is fixedly connected to a support plate 409, and a fixing hole 410 is provided on the support plate 409. A column 501 is inserted between the fixing block 401 with an opening at the bottom and the fixing hole 410. Two racks 406 are relatively fixedly connected to the top of the shell 404. The two racks 406 are symmetrically arranged about the side plate 403. A second motor 407 is installed on the side plate 403. The output end of the second motor 407 is keyed to two gears 405. The two gears 405 are symmetrically arranged about the side plate 403. The two gears 405 are respectively meshed with the two racks 406. A battery 408 is installed on the side plate 403, and the battery 408 is electrically connected to the second motor 407.

[0035] When the coated parts need to be transported from other stations to the coating machine door for loading, the movable plate 301 can be controlled by motor 1 205 to move to the vicinity of the loading station, the column 501 can be placed on the ground and held by hand, or placed on a designated placement rack, and the coated parts can be hung on the hook 502 on the column 501, and the column 501 is further inserted into the interior of the fixing hole 410 on the support plate 409, and the top of the column 501 corresponds to the hole at the bottom of the fixed block 401, and the motor 2 407 is started to realize the simultaneous rotation of the two gears 405 and drive the two racks 406 to rise, and then the shell 404 is The outer wall of the side panel 403 rises, and finally the support plate 409 rises to drive the column 501 to be inserted into the interior of the fixed block 401, completing the fixation of the column 501 and realizing the suspension of the coated part. The motor 1 205 is continued to be started to realize the gear disc 206 to drive the belt 207 to rotate, completing the suspension and long-distance transportation of the coated part. When the coated part reaches the door of the PVD coating machine, the motor 1 205 stops rotating, and further reverse rotation of the motor 2 407 realizes the lowering of the rack 406, and further lowering of the support plate 409. At this time, the column 501 can be taken out and the coated part can be placed inside the PVD vacuum coating machine for coating.

[0036] Specifically, the driving mechanism 2 includes a fixed frame 201. The bottom of the mounting frame 1 is fixedly connected to the fixed frame 201 with an arc-shaped structure on both sides by screws. The bottom of the fixed frame 201 is relatively fixedly connected to two connecting bars 202. The bottoms of the two connecting bars 202 are fixedly connected to an annular guide rail 203. Two fixed plates 204 are fixedly connected between the annular guide rail 203 and the fixed frame 201. The opposite sides of the two fixed plates 204 are fixedly connected to the two ends of the two connecting bars 202. The two fixed plates 204 are rotatably connected to a gear disk 206. A belt 207 is connected between the two toothed discs 206, a motor 205 is mounted on one of the fixed plates 204, and the output end of the motor 205 is key-connected to one of the toothed discs 206. A plurality of universal joints 303 are fixedly connected to a movable plate 301, and the movable plate 301 is located at the bottom of the annular guide rail 203. Two sets of rollers 302 are connected to the plurality of movable plates 301 for relative rotation, and the two sets of rollers 302 are respectively connected to the two sides of the annular guide rail 203 for rolling connection, and a fixed block 401 is fixedly connected to the bottom of the movable plate 301;

[0037] When the coated workpiece is transported over a long distance, it can be transported through the annular guide rail 203. First, the annular guide rail 203 needs to be installed. During installation, multiple mounting brackets 1 are installed on the indoor ceiling. The fixed frame 201 and the multiple mounting brackets 1 are fixed with screws. Two connecting strips 202 are welded relative to each other at the bottom of the fixed frame 201. The annular guide rail 203 is fixedly connected at the bottom of the two connecting strips 202. In this way, two sets of rollers 302 can be installed on the annular guide rail 203, and the two are connected in a rolling manner. Two fixed plates 204 are fixedly connected to the annular guide rail 203, so that the gear disc 206 and the motor 1 205 can be installed. The two gear discs 206 are rotatably connected to the fixed plate 204, and a belt 207 is installed between the two gear discs 206. By installing a universal joint 303 between the belt 207 and the movable plate 301, the belt 207 can rotate when the motor 1 205 rotates. Furthermore, the movable plate 301 can move at the bottom of the annular guide rail 203, and the moving path of multiple movable plates 301 is the rotation path of the belt 207.

[0038] Specifically, the limiting mechanism 7 includes internal teeth 701. A plurality of internal teeth 701 are equidistantly provided at the bottom of the slide plate 402. A sliding post 703 is slidably connected to the interior of the fixed block 401. The sliding post 703 abuts against the top of the column 501. A tooth plate 702 is fixedly connected to the top of the sliding post 703. The tooth plate 702 meshes with the internal teeth 701.

[0039] When hanging coated parts of different sizes, it is necessary to adjust the distance between the column 501 and the side plate 403 to ensure that the side plate 403 does not block the hanging of the workpiece on the hook 502. Before the column 501 full of coated parts is placed on the support plate 409, the distance between the side plate 403 and the bottom center of the fixed block 401 can be adjusted according to the width of the coated parts. When adjusting, it is only necessary to horizontally move the slide 402 on the fixed block 401 before the column 501 is fixed by the support plate 409. The distance between the side plate 403 and the column 501 can be adjusted by expanding the slide 402 outward, which is conducive to the hanging and transportation of coated parts of different sizes. After adjusting the distance, the hanging The column 501 with the workpiece is placed on the designated fixing hole 410, and the motor 2 407 is started to realize that the gear 405 drives the rack 406 to rise, and the support plate 409 further rises to push the column 501 upward, and the column 501 is inserted into the hole at the bottom of the fixed block 401. As the support plate 409 rises, the column 501 resists and rises the sliding column 703 inside the fixed block 401. As the sliding column 703 rises, the tooth plate 702 on its top resists and engages with the inner teeth 701 at the bottom of the slide 402, completing the fixation of the support plate 409 to the column 501 while also limiting the slide 402, which is beneficial for hanging and long-distance transportation of coated parts of different sizes.

[0040] Specifically, two sets of lubrication mechanisms 6 are relatively installed on each movable plate 301, and the lubrication mechanism 6 includes two connecting plates 602. Two connecting plates 602 are relatively installed on the movable plate 301. The two connecting plates 602 are fixedly connected to the oil box 601. The bottom of the two oil boxes 601 is provided with an oil leakage slit 605. The bottom of the two oil boxes 601 is bonded with a sponge strip 603. The opposite sides of the two sponge strips 603 are rollingly connected to the two sets of rollers 302; the lubrication mechanism 6 also includes a push column 608. The opposite sides of the two oil boxes 601 are slidably connected to two push columns 608. Each of the four push posts 608 is provided with two vertical plates 607 fixedly connected to the push posts 608. The bottom of each vertical plate 607 is bonded with a rubber pad 606 that contacts the oil leakage seam 605. A spring 610 is clamped between the push posts 608 and the oil box 601. Two baffles 604 are fixedly connected to both sides of the connecting strip 202. The ends of the baffles 604 are in an arc-shaped structure. The ends of the four push posts 608 are rotatably connected to the drive wheels 609, which contact the baffles 604. Two connecting plates 602 are installed opposite to each other on each movable plate 301, and the oil box 601 is fixedly connected to the two connecting plates 602.

[0041] Lubricating oil is injected into the oil box 601. As the movable plate 301 moves at the bottom of the annular guide rail 203, the two push pins 608 on the two oil boxes 601 will pass through the two sets of baffles 604 on the connecting bar 202. When the push pins 608 pass through the baffles 604, the driving wheels 609 on the two sets of push pins 608 will roll with the arc-shaped parts of the baffles 604. The push pins 608 will also move toward the inside of the oil box 601 as the movable plate 301 moves, and the spring 610 contracts. When the push pins 608 are squeezed, the vertical plate 607 is driven to move in the oil box. The inside of the box 601 moves, and the rubber pad 606 that the vertical plate 607 contacts will open the oil leakage slit 605 at the bottom of the oil box 601. The oil leakage slit 605 will seep oil onto the sponge strip 603, and the roller 302 will be contaminated with the lubricating oil on the sponge strip 603. As the roller 302 rolls on the annular guide rail 203, the lubricating oil will be smeared on the annular guide rail 203, reducing the friction between the roller 302 and the annular guide rail 203 and reducing the wear between the two, thereby preventing the uneven surface of the annular guide rail 203 from causing the suspended workpiece to shake and fall, thereby preventing the workpiece from being damaged.

[0042] When the present invention is used, first, when the coated workpiece is transported over a long distance, it can be transported through the annular guide rail 203. First, the annular guide rail 203 needs to be installed. During installation, multiple mounting brackets 1 are installed on the indoor ceiling, and the fixing frame 201 and the multiple mounting brackets 1 are fixed by screws. Two connecting strips 202 are welded relative to each other at the bottom of the fixing frame 201, and the annular guide rail 203 is fixedly connected at the bottom of the two connecting strips 202. Then, two sets of rollers 302 can be installed on the annular guide rail 203, and the two are rollingly connected. The two fixed plates 204 are fixedly connected between the guide rails 203, so that the toothed disc 206 and the motor 205 can be installed. The two toothed discs 206 and the fixed plate 204 are rotatably connected, and a belt 207 is installed between the two toothed discs 206. By installing a universal joint 303 between the belt 207 and the movable plate 301, the belt 207 can be rotated when the motor 205 rotates. Further, the movable plate 301 can move at the bottom of the annular guide rail 203, and the moving path of the multiple movable plates 301 is the rotation path of the belt 207. When the coated parts need to be transported from other stations to the coating station, the belt 207 can be rotated. When loading materials at the film machine door, the motor 1 205 can be used to control the movable plate 301 to move to the vicinity of the loading station, and the column 501 can be placed on the ground and held by hand, or placed on a designated placement rack, and the coated parts can be hung on the hook 502 on the column 501, and the column 501 is further inserted into the interior of the fixing hole 410 on the support plate 409, and the top of the column 501 corresponds to the hole at the bottom of the fixed block 401, and the motor 2 407 is started to realize the simultaneous rotation of the two gears 405 and drive the two racks 406 to rise, so that the shell 404 is on the outer wall of the side plate 403. The support plate 409 rises, and finally the support plate 409 rises and drives the column 501 to be inserted into the interior of the fixed block 401, completing the fixation of the column 501 and realizing the suspension of the coated part. The motor 1 205 is then started to realize the rotation of the gear plate 206 to drive the belt 207 to complete the suspension and long-distance transportation of the coated part. When the coated part reaches the door of the PVD coating machine, the motor 1 205 stops rotating, and the motor 2 407 is further rotated in the reverse direction to realize the lowering of the rack 406, and further the support plate 409 is lowered. At this time, the column 501 can be taken out and the coated part can be placed inside the PVD vacuum coating machine for coating.

[0043] Then, when hanging coated parts of different sizes, it is necessary to adjust the distance between the column 501 and the side plate 403 to ensure that the side plate 403 does not block the hanging of the workpiece on the hook 502. Before the column 501 full of coated parts is placed on the support plate 409, the distance between the side plate 403 and the bottom center of the fixed block 401 can be adjusted according to the width of the coated parts. When adjusting, it is only necessary to horizontally move the slide 402 on the fixed block 401 before the column 501 is fixed by the support plate 409. The distance between the side plate 403 and the column 501 can be adjusted by expanding the slide 402 outward, which is conducive to the hanging and transportation of coated parts of different sizes. After adjusting the distance, The column 501 with the workpiece suspended thereon is placed on the designated fixing hole 410, and the second motor 407 is started to realize that the gear 405 drives the rack 406 to rise, and the support plate 409 further rises to push the column 501 upward, and the column 501 is inserted into the hole at the bottom of the fixed block 401. As the support plate 409 rises, the column 501 resists and rises the sliding column 703 inside the fixed block 401. As the sliding column 703 rises, the tooth plate 702 on its top resists and engages with the inner teeth 701 at the bottom of the slide plate 402, completing the fixation of the support plate 409 to the column 501 and also limiting the position of the slide plate 402, which is conducive to the suspension and long-distance transportation of coated parts of different sizes;

[0044] Finally, two connecting plates 602 are installed opposite to each other on each movable plate 301, and oil boxes 601 are fixedly connected to the two connecting plates 602. Lubricating oil is injected into the interior of the oil box 601. As the movable plate 301 moves at the bottom of the annular guide rail 203, the two push pins 608 on the two oil boxes 601 will pass through the two sets of baffles 604 on the connecting bar 202. When the push pins 608 pass through the baffles 604, the driving wheels 609 on the two sets of push pins 608 will roll with the arc-shaped part of the baffles 604, and the push pins 608 will also move toward the interior of the oil box 601 as the movable plate 301 moves. The spring 610 When the push column 608 is squeezed, it drives the vertical plate 607 to move inside the oil box 601, and the rubber pad 606 that the vertical plate 607 contacts will open the oil leakage slit 605 at the bottom of the oil box 601. The oil leakage slit 605 will seep oil onto the sponge strip 603, and the roller 302 will be contaminated with the lubricating oil on the sponge strip 603. As the roller 302 rolls on the annular guide rail 203, the lubricating oil will be smeared on the annular guide rail 203, reducing the friction between the roller 302 and the annular guide rail 203 and reducing the wear between the two, thereby preventing the uneven surface of the annular guide rail 203 from causing the suspended workpiece to shake and fall, thereby damaging the workpiece.
