Description

Technical Field

[0001] The present invention relates to the technical field of screen mounting, and in particular to a screen mounting device. Background Art

[0002] VR (Virtual Reality) is a technology that provides an immersive feeling in a computer-generated, interactive three-dimensional environment by comprehensively utilizing computer graphics systems and various reality and control interface devices.

[0003] Virtual reality head-mounted displays (VR glasses) are a product that integrates simulation technology, computer graphics, human-computer interface technology, multimedia technology, sensor technology, and network technology. Leveraging computers and the latest sensor technology, they offer a brand-new means of human-computer interaction. VR glasses are a groundbreaking product, not only surprising and delighting every enthusiast who experiences them, but also captivating because of the unknowns surrounding their creation and future.

[0004] The principle of VR glasses is similar to that of our eyes. The two lenses are equivalent to eyes, but they are far less "intelligent" than human eyes. In addition, VR glasses generally split the content into two halves and use lenses to achieve superimposed imaging. The center of the human pupil, the center of the lens, and the center of the screen (after splitting the screen) should be in a straight line. At this time, it is necessary to adjust the "pupillary distance" of the lens to coincide with the pupil distance of the human eye, and then use software to adjust the center of the picture to ensure that the three points are in a straight line, so as to obtain the best visual effect. In VR glasses, the screen needs to be filmed. The traditional mounting method is to manually assemble the film. The manual operation will cause inaccurate alignment and the product precision is not stable enough. Since the relative position of the film and the product is very high when assembling VR glasses, manual mounting can easily affect the product quality and increase the defective rate of the product.

[0047] The following elaborates on the preferred embodiments of the present invention in conjunction with the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making the protection scope of the present invention more clearly defined.

[0048] Referring to the accompanying drawings, a screen mounting device includes: a film loading mechanism 3, a peeling mechanism 5, a screen feeding mechanism 6, and a mounting mechanism 7. This screen mounting device is used for mounting a film on a screen. First, the release paper 11 on the film 1 is peeled off by the peeling mechanism 5, and then the film is mounted on the screen by the mounting mechanism 7.

[0049] The film loading mechanism 3 is used for loading the film. The film loading mechanism 3 includes a magazine 31, a pallet 32, a lifting module 33, a moving component 34, and a loading suction nozzle 35. The magazine 31 is arranged on the pallet 32, and the magazine 31 and the pallet 32 are detachably connected, that is, the magazine 31 can be directly placed on the pallet 32. In this way, stacks of films can be pre-placed in the magazine 31. When the film in the magazine 31 on the film loading mechanism 3 is used up, the magazine 31 is directly removed, and another magazine 31 filled with the film 1 is placed on the pallet 32, effectively avoiding the occurrence of an empty slot and preventing the screen mounting device from running empty, further improving the mounting efficiency. To better fix the magazine 31, the magazine 31 and the pallet 32 can also be detachably connected by bolts or the like.

[0050] The magazine 31 includes a bottom plate 311, a support plate 312, and guide posts 313. The support plate 312 is arranged on one side of the bottom plate 311, that is, the magazine 31 is arranged with a bottom and only one side surface, which is convenient for taking and placing the film in the magazine 31. The guide posts 313 are arranged on the bottom plate 311, and the guide posts 313 are located on the diagonal of the bottom plate 311. The setting of the guide posts 313 can effectively prevent the displacement of the film. For example, when a film is taken away, the next film in contact is likely to be displaced or even dropped under the action of inertia. The film is restricted within the range of the magazine 31 by the guide posts 313 to prevent it from dropping.

[0051] The pallet 32 is connected to the lifting module 33. The lifting module 33 is driven by a motor, and the lifting module 33 can be a servo motor lifting module 33. The lifting module 33 drives the pallet 32 to move up and down. By the lifting module 33, the pallet 32 drives the magazine 31 to rise, so that the film in the magazine 31 can contact the loading suction nozzle 35, facilitating the loading suction nozzle 35 to suck the film and take the material.

[0052] The loading suction nozzle 35 is connected to the moving component 34, and the moving component 34 drives the loading suction nozzle 35 to move. The moving component 34 includes a left-right moving module 341, an up-down moving module 342, and a slide rail 343. The left-right moving module 341 and the up-down moving module 342 are connected to the slide rail 343, and the left-right moving module 341 and the up-down moving module 342 are slidably connected to the slide rail 343. The left-right moving module 341 and the up-down moving module 342 may include a driving member and a slider, or may only include a driving member. For example, the left-right moving module 341 includes a driving member and a slider, and the slider is driven by the driving member to move on the slide rail 343; the up-down moving module 342 only includes a driving member, and the loading suction nozzle 35 is connected to the driving member of the up-down moving module 342, and the loading suction nozzle 35 is directly driven by the driving member of the up-down moving module 342 to move up and down. The driving members of the left-right moving module 341 and the up-down moving module 342 can both be selected as air cylinders to drive the loading suction nozzle 35 to move.

[0053] The loading suction nozzle 35 is used to suck the film, and the loading suction nozzle 35 can be selected as the suction nozzle of the mounter. The loading suction nozzle 35 is arranged on the up-down moving module 342, and the up-down moving module 342 drives the loading suction nozzle 35 to perform up-down movement, and the left-right moving module 341 drives the loading suction nozzle 35 to move left and right on the slide rail 343. The moving component 34 drives the loading suction nozzle 35 mainly to move left and right, that is, to move the film from the magazine 31 to other positions, such as the turntable mechanism 4. When the tray raises the magazine 31 to a certain position, if the loading suction nozzle 35 has not been able to suck the film at this time, the up-down moving module 342 can be used to drive the loading suction nozzle 35 to perform a small range of up-down movement.

[0054] The film loading mechanism 3 further includes an electrostatic eliminator bar 36, and the electrostatic eliminator bar 36 is arranged above the magazine 31. Since the film is very thin, static electricity is easily generated between the films. The electrostatic eliminator bar 36 is used to eliminate the static electricity between the films, which is convenient for the loading suction nozzle 35 to suck the film.

[0055] The film loading mechanism 3 further includes a loading sensor 37, and the loading sensor 37 is arranged above the magazine 31 and is located on one side of the film. The loading sensor 37 can be selected as an optical fiber sensor or a photoelectric sensor. The loading sensor 37 is used to sense the rising height of the film, so as to facilitate knowing the distance that the loading suction nozzle 35 needs to descend. And, since the loading sensor 37 is located on one side of the film, the film can also be limited by the rack for fixing the loading sensor 37 to prevent the film from shifting in the magazine 31.

[0056] To better fix the film coming from the film loading mechanism 3, the screen mounting device further includes a turntable mechanism 4. The turntable mechanism 4 includes a turntable bracket 5241, a turntable body 42, a turntable motor 43, suction cups 44, and a turntable sensor 45. The turntable body 42 is arranged on the turntable bracket 5241. The turntable body 42 is connected to the turntable motor 43, and the turntable motor 43 drives the turntable body 42 to rotate. The suction cups 44 are arranged on the turntable body 42, and the suction cups 44 are lower than the peeling suction nozzle 51. One film is placed on one suction cup 44, and the film is sucked and fixed on the turntable body 42 by the suction cup 44. A plurality of suction cups 44 are arranged on the turntable body 42, and the suction cups 44 are arranged in a circumferential array on the turntable body 42. For example, there are four suction cups 44 on the turntable body 42, representing four workstations. When the motor drives the turntable body 42 to rotate, one side is one-fourth of the circumference of the turntable body 42.

[0057] To better transfer the rotational power of the turntable motor 43, the turntable mechanism 4 further includes a cam divider 46. The cam divider 46 is connected to the turntable motor 43, and the cam divider 46 is located below the turntable body 42.

[0058] The turntable sensor 45 is arranged on the side of the turntable body 42. The turntable sensor 45 can be an infrared sensor. The turntable sensor 45 senses whether there is a film on the suction cup 44 close to the turntable sensor 45. When there is a film on the suction cup 44, the suction cup 44 rotates once, turning the next suction cup 44 without a film to the vicinity of the turntable sensor. The loading suction nozzle 35 places the next film sucked from the magazine 31 onto this empty suction cup 44.

[0059] The peeling mechanism 5 peels the release paper 11 on the film. The peeling mechanism 5 includes a peeling suction nozzle 51, a bracket 52, and a driving assembly 53. The peeling suction nozzle 51 is connected to the driving assembly 53 through the bracket 52, and the driving assembly 53 drives the peeling suction nozzle 51 to move in the direction where the release paper 11 can be torn off. The driving assembly 53 can be a rotary cylinder. The rotary cylinder drives the peeling suction nozzle 51 to rotate, thereby peeling the release paper 11 on the film.

[0060] The peeling mechanism 5 further includes a waste bin 54. The waste bin 54 is located on one side of the peeling suction nozzle 51, and the bottom end of the waste bin 54 is lower than the peeling suction nozzle 51. The peeling suction nozzle 51 rotates with the peeled release paper 11 above the waste bin 54, and the peeling suction nozzle 51 relaxes, and the release paper 11 falls into the waste bin 54.

[0061] The stripping mechanism 5 further includes a waste drawer 55, which is located below the waste bin 54 and is in communication with the waste bin 54. The waste drawer 55 is detachably connected to the waste bin 54, that is, the waste drawer 55 can be pulled out like an ordinary drawer for discharging materials. Since the waste drawer 55 is in communication with the waste bin 54, the release paper 11 that falls into the waste bin 54 will directly fall into the waste drawer 55. When the release paper 11 in the waste drawer 55 is full, the waste drawer 55 is pulled out to pour out the release paper 11. Through the setting of the waste drawer 55, it is convenient to collect the torn release paper 11, and the waste drawer 55 can be manually pulled out for cleaning after being full.

[0062] The screen feeding mechanism 6 is used for feeding the screen, and the screen is supported and fixed by the screen carrier 2. The screen feeding mechanism 6 includes a support assembly 61, a positioning assembly 62 and a blocking assembly 63. The positioning assembly 62 is arranged above the support assembly 61, and the positioning assembly 62 fixes the screen carrier 2 on the support assembly 61. The blocking assembly 63 is arranged on one side of the support assembly 61, and the top end of the blocking assembly 63 is higher than the support assembly 61. Through the blocking assembly 63, continuous feeding of the screen is avoided, especially when a production line is connected to the device, to prevent overloading of the device due to excessive feeding.

[0063] The support assembly 61 includes a support table 611 and a lifting cylinder 612. A positioning groove 6111 is arranged on the support table 611. The lifting cylinder 612 is arranged below the support table 611 and is connected to the support table 611. The lifting cylinder 612 drives the support table 611 to move up and down, and the support table 611 is lifted and fixed by the lifting cylinder 612.

[0064] The positioning assembly 62 includes positioning jaws 621, jaw cylinders 622 and pressing cylinders 623. The positioning jaws 621 pass through the positioning groove 6111 of the support table 611. The positioning jaws 621 are symmetrically arranged in the positioning groove 6111 of the support table 611, and an accommodation cavity is formed between the positioning jaws 621. The screen carrier 2 is located in this accommodation cavity. The positioning jaws 621 include pressing blocks 6211, and the edge of the screen carrier 2 is pressed by the pressing blocks 6211. The jaw cylinders 622 are connected to the positioning jaws 621, and the jaw cylinders 622 drive the positioning jaws 621 to move left and right. The opening and clamping of the positioning jaws 621 are controlled by the jaw cylinders 622, and the jaw cylinders 622 can be selected as sliding cylinders. The pressing cylinders 623 are connected to the positioning jaws 621 through the jaw cylinders 622, and the pressing cylinders 623 drive the positioning jaws 621 to move up and down.

[0065] The blocking assembly 63 includes a roller 631 and a blocking cylinder 632. The blocking cylinder 632 is connected to the roller 631, and the blocking cylinder 632 drives the roller 631 to move up and down. The roller 631 is located on one side of the support table 611. The roller 631 can be a damping roller 631, and an elastic protective sleeve is provided on the surface of the damping roller 631. The material of the elastic protective sleeve is rubber to reduce damage to the screen carrier 2 caused by the roller 631 during the blocking process. The lifting cylinder 612, the pressing cylinder 623, and the blocking cylinder 632 can all use conventional cylinders, and their function is to drive another object to move up and down.

[0066] The screen feeding mechanism 6 further includes a fixing assembly 64. The fixing assembly 64 includes a fixing block 641, a connecting block 642, and a fixing cylinder 643. The connecting block 642 passes through the fixing block 641, and the fixing block 641 is rotatably connected to the connecting block 642. One end of the fixing block 641 is connected to the fixing cylinder 643, and the fixing cylinder 643 drives the fixing block 641 to move left and right. The other end of the fixing block 641 is arranged above the support table 611. Since the fixing block 641 is rotatably connected to the connecting block 642, when the fixing cylinder 643 pushes one end of the fixing block 641 to move, it drives the other end of the fixing block 641 to swing, and the other end of the fixing block 641 presses down to fix the support table 611.

[0067] The mounting mechanism 7 is used to connect the film feeding mechanism 3 and the screen feeding mechanism 6, and the film is mounted on the screen through the mounting mechanism 7. The mounting mechanism 7 includes an X-axis module group 71, a Y-axis module group 72, a Z-axis module group 73, a picking gripper 74, and a CCD camera 75.

The X-axis module group 71, the Y-axis module group 72, and the Z-axis module group 73 can use conventional three-axis module groups, which will not be elaborated here. The picking gripper 74 is arranged on the X-axis module group 71, and the shape of the picking gripper 74 is adapted to the shape of the material to be picked. The X-axis module group 71, the Y-axis module group 72, and the Z-axis module group 73 drive the picking gripper 74 and the CCD camera 75 to move in the X-axis direction, Y-axis direction, and Z-axis direction respectively.

[0068] The CCD camera 75 is connected to the X-axis module group 71. The CCD camera 75 is arranged above the picking gripper 74. The CCD camera 75, that is, a charge-coupled device, can use a conventional CCD camera 75. The CCD camera 75 is used to take pictures of the film 1 after the release paper 11 is peeled off, so as to obtain the position of the film. The screen on the screen carrier 2 is brought to the film 1 for fitting through the picking gripper 74, and the mounting of the film 1 and the screen is completed.

[0069] The screen mounting device further includes a robot mechanism 8, on which a finished product gripper 81 is mounted. The finished product gripper 81 picks up the mounted screen finished product, and the finished product can be placed on the support table 611 of the screen feeding mechanism 6 and flow into the next process.

[0070] During actual use, an operator places the film in the magazine 31, places the magazine 31 on the pallet 32 and pushes it into place. The lifting module 33 in the film loading mechanism 3 drives the film to the suction height. The loading suction nozzle 35 in the film loading mechanism 3 picks up the film and places it on the suction cup 44 of the turntable mechanism 4. The release paper 11 of the film on the turntable is peeled off by the peeling suction nozzle 51 in the peeling mechanism 5. The support table 611 carrying the screen carrier 2 with the screen on it flows into the device by a production line (not shown in the figure). The blocking cylinder 632 blocks the support table 611, and the lifting cylinder 612 lifts and fixes the support table 611. The picking gripper 74 in the mounting mechanism 7 picks up the screen carrier 2 on the support table 611, and the CCD camera 75 in the mounting mechanism 7 captures the position of the film. According to the position of the film, the mounting mechanism 7 aligns and fits the screen on the screen carrier 2 onto the film 1, completing the mounting of one screen.

[0071] The turntable body 42 in the turntable mechanism 4 rotates, rotating the fitted screen finished product to the unloading position. The finished product gripper 81 in the robot mechanism 8 clamps the finished product on the turntable body 42, picks it up, and places it back on the support table 611 on the production line. The support table 611 flows into the subsequent device through the production line.
