Description

Technical Field

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

[0002] PVD is physical vapor deposition, and vacuum coating is an advanced surface treatment technology. By converting solid materials into gaseous atoms or molecules in a vacuum environment and depositing them on the surface of a substrate to form a thin film, new properties or appearances can be imparted to the materials. When suspending and conveying PVD vacuum coating, a circular guide rail is generally used for suspension conveying. The working principle of the circular guide rail is based on the rolling friction principle, and the movement is transmitted through the rolling of the rollers or balls on the slider on the rail.

[0003] However, currently when vacuum coating some workpieces, the workpieces are suspended on a suspension rack, and then the support frame for suspending the workpieces is installed and fixed to the slider on the circular guide rail. The circular guide rail drives the suspended workpieces to be conveyed near the door of the coating machine to complete the suspension and conveyance of the workpieces for long-distance coating. The support frame for suspending the workpieces usually uses a fixed frame to cooperate with the moving block on the circular guide rail for installation and fixation. It is difficult to slide when the fixed frame and the moving block are directly welded together, and it is difficult to adjust the outward expansion range of the fixed frame. When the suspended workpiece is relatively large, the workpiece will touch the fixed frame for suspending the workpiece, resulting in difficulty in fixing the fixed frame to the moving block and difficulty in transporting the workpiece on the fixed frame; the conveyance is realized by the cooperation of the circular guide rail, the slider and the rollers. The rollers are located on both sides of the circular guide rail to provide support between the hanging parts and guide the moving block. The rollers are prone to wear after long-term rolling with the circular guide rail. There is no lubrication mechanism on the moving block to lubricate the slide rail, and the slide rail wears too fast. The unevenness of the slide rail easily causes the coating parts to shake during conveyance and fall off, damaging the coating parts. Summary of the Invention

Detailed implementation manners

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

The column 501 can be placed on the ground and held by hand, or placed on the designated placement rack. The coated part can be hung on the hook 502 on the column 501. Further, the column 501 is inserted into 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 fixing block 401. The second motor 407 is started to make the two gears 405 rotate simultaneously and drive the two racks 406 to rise. Then the housing 404 rises on the outer wall of the side plate 403. Finally, the support plate 409 rises to drive the column 501 to be inserted into the fixing block 401, completing the fixing of the column 501 and realizing the suspension of the coated part. The first motor 205 is continuously started to make the gear disc 206 drive the belt 207 to rotate, completing the suspension and long-distance conveying of the coated part. When the coated part reaches the door of the PVD coating machine, the first motor 205 stops rotating. Further, the second motor 407 is reversely rotated to make the rack 406 descend. Further, the support plate 409 descends. At this time, the column 501 can be taken out and the coated part can be placed into the PVD vacuum coating machine for coating.

[0023] Specifically, the driving mechanism 2 includes a fixed frame 201. The bottom of the mounting frame 1 is fixedly connected by screws to the fixed frame 201 with an arc-shaped structure on both sides. Two connecting bars 202 are fixedly connected to the bottom of the fixed frame 201. A circular guide rail 203 is fixedly connected to the bottom of the two connecting bars 202. Two fixing plates 204 are fixedly connected between the circular guide rail 203 and the fixed frame 201. The opposite sides of the two fixing plates 204 are fixedly connected to the two ends of the two connecting bars 202. Two toothed discs 206 are rotatably connected to the two fixing plates 204 respectively. A belt 207 is connected between the two toothed discs 206. A first motor 205 is installed on one of the fixing plates 204. The output end of the first motor 205 is key-connected to one of the toothed discs 206. A moving plate 301 is fixedly connected to each of the multiple universal joints 303. The moving plate 301 is located at the bottom of the circular guide rail 203. Two sets of rollers 302 are rotatably connected to each of the multiple moving plates 301 respectively. The two sets of rollers 302 are respectively in rolling connection with the two sides of the circular guide rail 203. The fixed block 401 is fixedly connected to the bottom of the moving plate 301; When transporting the coated workpieces over a long distance, the circular guide rail 203 can be used for transportation. First, the circular guide rail 203 needs to be installed. During installation, multiple mounting frames 1 are installed on the indoor ceiling, and the fixed frame 201 is fixedly connected to the multiple mounting frames 1 by screws. Two connecting bars 202 are welded to the bottom of the fixed frame 201 relatively. The circular guide rail 203 is fixedly connected to the bottom of the two connecting bars 202. Then, it is realized that the two sets of rollers 302 can be installed on the circular guide rail 203 and are in rolling connection with each other. Two fixing plates 204 are fixedly connected between the fixed frame 201 and the circular guide rail 203, so that the toothed discs 206 and the first motor 205 can be installed. The two toothed discs 206 are rotatably connected to the fixing plates 204. The belt 207 is installed between the two toothed discs 206. By installing the universal joints 303 between the belt 207 and the moving plate 301, when the first motor 205 rotates, the belt 207 rotates, and further, the moving plate 301 can move at the bottom of the circular guide rail 203, and the moving paths of the multiple moving plates 301 are the rotation paths of the belt 207.

[0024] Specifically, the limiting mechanism 7 includes an internal gear 701. A plurality of internal gears 701 are equidistantly arranged at the bottom of the sliding plate 402. A sliding column 703 is slidably connected inside the fixed block 401. The sliding column 703 abuts against the top of the column 501. A toothed plate 702 is fixedly connected to the top of the sliding column 703. The toothed plate 702 meshes with the internal gear 701; 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 plate 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 plate 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 plate 402, so that the support plate 409 fixes the column 501 while limiting the slide plate 402, which is beneficial to the suspension and long-distance transportation of coated parts of different sizes.

[0025] Specifically, two groups 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, and the two connecting plates 602 are fixedly connected with oil boxes 601. The bottoms of the two oil boxes 601 are provided with oil leakage slits 605. The bottoms of the two oil boxes 601 are bonded with sponge strips 603, and the opposite sides of the two sponge strips 603 are rollingly connected with the two groups of rollers 302; the lubrication mechanism 6 also includes a push column 608, and the opposite sides of the two oil boxes 601 are slidably connected with two push columns 608. Two vertical plates 607 fixedly connected to the push posts 608 are arranged inside, and rubber pads 606 that contact the oil leakage seam 605 are bonded to the bottom of the vertical plates 607, and springs 610 are 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, and 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 driving wheels 609, and the driving wheels 609 contact the baffles 604; two connecting plates 602 are relatively installed on each movable plate 301, and the oil box 601 is fixedly connected to the two connecting plates 602; Lubricating oil is injected into the interior of the oil box 601. As the moving plate 301 moves at the bottom of the annular guide rail 203, the two push columns 608 on the two oil boxes 601 will pass through the two groups of baffles 604 on the connecting bar 202. When the push columns 608 pass through the baffles 604, the driving wheels 609 on the two push columns 608 will roll along the arc-shaped parts of the baffles 604. Also, the push columns 608 will move into the interior of the oil box 601 as the moving plate 301 moves, and the springs 610 will contract. When the push columns 608 are squeezed, they will drive the vertical plates 607 to move inside the oil box 601, and the rubber pads 606 against which the vertical plates 607 abut will open the oil leakage slots 605 at the bottom of the oil box 601. The oil leakage slots 605 will seep oil onto the sponge strips 603, and the rollers 302 will pick up the lubricating oil on the sponge strips 603. As the rollers 302 roll on the annular guide rail 203, the lubricating oil will be applied to the annular guide rail 203, reducing the friction between the rollers 302 and the annular guide rail 203 and reducing the wear of both, and preventing the suspended workpieces from shaking and falling due to the uneven surface of the annular guide rail 203, which may cause damage to the workpieces.

[0026] When the present invention is in use, first, when transporting the workpiece to be coated 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, a plurality of mounting brackets 1 are installed on the indoor ceiling, and the fixing frame 201 is fixed to the plurality of mounting brackets 1 with screws. Two connecting bars 202 are welded opposite to each other at the bottom of the fixing frame 201, and the annular guide rail 203 is fixedly connected to the bottom of the two connecting bars 202. Then, two sets of rollers 302 can be installed on the annular guide rail 203, and the two are in rolling connection. Two fixing plates 204 are fixedly connected between the fixing frame 201 and the annular guide rail 203, and then the installation of the toothed discs 206 and the first motor 205 can be carried out. The two toothed discs 206 are rotatably connected between the fixing plates 204, and a belt 207 is installed between the two toothed discs 206. By installing a universal joint 303 between the belt 207 and the moving plate 301, when the first motor 205 rotates, the belt 207 rotates. Further, the moving plate 301 can move at the bottom of the annular guide rail 203, and the moving paths of the plurality of moving plates 301 are the rotation paths of the belt 207. When the coated part needs to be transported from another station to the loading position at the door of the coating machine, the first motor 205 can be controlled to move the moving plate 301 near the loading station. The column 501 can be placed on the ground and held by hand, or placed on the designated placement rack, and the coated part can be hung on the hook 502 on the column 501. Further, the column 501 is inserted into 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 fixing block 401. The second motor 407 is started to make the two gears 405 rotate simultaneously and drive the two racks 406 to rise. Then, the outer shell 404 rises on the outer wall of the side plate 403, and finally the support plate 409 rises to drive the column 501 to be inserted into the fixing block 401, completing the fixation of the column 501 and realizing the suspension of the coated part. The first motor 205 is continuously started to make the toothed disc 206 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 first motor 205 stops rotating. Further, the second motor 407 is rotated in the reverse direction to make the rack 406 descend. Further, the support plate 409 descends. At this time, the column 501 can be taken out and the coated part can be placed into the PVD vacuum coating machine for coating; 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 plate 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 plate 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 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, and as the support plate 409 rises, the column 501 resists and rises the sliding column 703 inside the fixed block 401, and as the sliding column 703 rises, the tooth plate 702 on the top thereof resists and engages with the inner teeth 701 at the bottom of the slide plate 402, and the support plate 409 is fixed to the column 501, and the slide plate 402 can be limited at the same time, which is conducive to the suspension and long-distance transportation of coated parts of different sizes; Finally, two connecting plates 602 are relatively installed on each moving 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 moving 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 groups of baffles 604 on the connecting strip 202, and when the push pins 608 pass through the baffles 604, the driving wheels 609 on the two groups 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 moving plate 301 moves, and the springs 610 The push column 608 contracts, and when the push column 608 is squeezed, the vertical plate 607 is driven 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, and 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, thereby reducing the friction between the roller 302 and the annular guide rail 203 and reducing the wear of the two, thereby preventing the uneven surface of the annular guide rail 203 from causing the suspended workpiece to shake and fall, thereby causing damage to the workpiece.
