Description

Technical Field

[0001] The utility model relates to the technical field of rolling equipment, in particular to an OLED screen rolling machine. Background Art

[0002] Since OLED (Organic Light Emitting Diode) display technology has the advantages of high contrast, wide viewing angle, fast response and rich colors due to its self-luminous characteristics, it has been widely used in the fields of smartphones, televisions, tablets, wearable devices and automotive displays. When installing an OLED screen on a shell (such as the shell of a computer display), adhesive is generally applied to both sides of the shell, and then the OLED screen is positioned on the shell. A rolling machine is used to apply uniform pressure to the OLED screen to better fit it with the shell, ensuring that the adhesive is fully effective to bond the OLED screen to the shell. The distance between the two rolling wheels of the existing OLED screen rolling machine is fixed, and it can only roll display screens of the same size, resulting in low flexibility. Therefore, an OLED screen rolling machine is proposed. Utility Model Content

[0030] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0031] In the description of the present invention, it should be understood that the terms "upper," "lower," "top," "bottom," "inner," "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate the description of the present invention and simplify the description. They are not intended to indicate or imply that the devices or elements referred to must have a specific orientation, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on the present invention. It should be noted that when a component is considered to be "connected" to another component, it may be directly connected to the other component or there may be a centrally located component.

[0032] The technical solution of the present invention will be further described below with reference to the accompanying drawings and through specific implementation methods.

[0033] Reference Figures 1 to 6The embodiment of the present invention provides an OLED screen rolling machine, comprising a frame 10, a carrier 20, a center positioning mechanism 30, a screen rolling mechanism 40, and a synchronous lifting and transferring mechanism 50. The carrier 20, the center positioning mechanism 30, the screen rolling mechanism 40, and the synchronous lifting and transferring mechanism 50 are all arranged on the frame 10. The carrier 20 is used to carry the OLED screen workpiece to be rolled; the center positioning mechanism 30 is used to position the workpiece placed on the carrier 20 so that the screen rolling mechanism 40 can roll the workpiece; the synchronous lifting and transferring mechanism 50 transfers the workpiece on the carrier 20 to the next workstation.

[0034] The screen rolling mechanism 40 includes a first rolling assembly 41 and a second rolling assembly 42 arranged above the carrier 20, and an adjustment assembly 43 is provided between the first rolling assembly 41 and the second rolling assembly 42 for adjusting the distance between the first rolling assembly 41 and the second rolling assembly 42. It should be noted that when the OLED screen is installed on the shell, the adhesive is applied to a pair of side edges of the shell. Therefore, when rolling the OLED display screen, only a pair of side edges of the OLED display screen need to be rolled, and the distance between the adhesives on both sides of the shell is different for OLED display screens of different sizes. Therefore, when rolling OLED display screens of different sizes, it is necessary to adjust the distance between the first rolling assembly 41 and the second rolling assembly 42. The OLED screen rolling machine disclosed in the embodiment of the present utility model adjusts the distance between the first rolling assembly 41 and the second rolling assembly 42 by the adjustment assembly 43.

[0035] Specifically, the scrolling mechanism 40 further includes a first bracket 44 fixed to the frame 10, a Y-direction movable frame 45 disposed on the first bracket 44, an X-direction movable frame 46 disposed on the Y-direction movable frame 45, and a Z-direction movable frame 47 disposed on the X-direction movable frame 46. The adjustment assembly 43 is disposed on the Z-direction movable frame 47. It should be noted that the Y-direction movable frame 45 is driven by a linear motor disposed on the first bracket 44 to achieve movement in the Y direction; the X-direction movable frame 46 is driven by a linear motor disposed on the Y-direction movable frame 45 to achieve movement in the X direction; and the Z-direction movable frame 47 is driven by a linear motor disposed on the X-direction movable frame 46 to achieve movement in the Z direction. The adjustment assembly 43 can be positioned above the workpiece to be processed by the Y-axis movable frame 45 and the X-axis movable frame 46, and then moved toward the direction close to the carrier 20 by the Z-axis movable frame 47, so that the first rolling assembly 41 and the second rolling assembly 42 are in contact with the workpiece to be processed and apply pressure, and finally the Y-axis movable frame 45 moves along the Y direction, thereby driving the first rolling assembly 41 and the second rolling assembly 42 to move along the Y direction to roll the workpiece.

[0036] Furthermore, the adjustment assembly 43 includes a fixed plate 431 mounted on the Z-axis movable frame 47. Driven gears 432 are disposed at both ends of the fixed plate 431. A drive motor 433 is disposed between the two driven gears 432. A driving gear 434 is disposed on the output shaft of the drive motor 433. The driving gear 434 and the driven gears 432 are connected by a toothed belt 435. Specifically, rotating wheels are disposed on either side of the driving gear 434. The driving gear 434 and the two rotating wheels are arranged in a triangular layout. The toothed belt 435 passes through the driving gear 434 and the rotating wheels, thereby increasing the tension between the toothed belt 435 and the driving gear 434. This allows the toothed belt 435 to rotate when the driving gear 434 rotates. It should be noted that the two driven gears 432 divide the toothed belt 435 into an upper belt and a lower belt. When the driving gear 434 drives the toothed belt 435, the upper belt and the lower belt move in opposite directions, i.e., the upper belt and the lower belt move toward or away from each other.

[0037] The adjustment assembly 43 also includes a first guide rail 436 disposed on the fixed plate 431. The first rolling assembly 41 includes a first movable plate 411, one end of which is fixed to the upper belt of the toothed belt 435 and the other end is slidably connected to the first guide rail 436. The second rolling assembly 42 includes a second movable plate 421, one end of which is fixed to the lower belt of the toothed belt 435 and the other end is slidably connected to the first guide rail 436. When the upper belt and the lower belt move toward or away from each other, the first rolling assembly 41 and the second rolling assembly 42 move toward or away from each other. The first rolling assembly 41 also includes a first buffer module 412, a first roller 413 disposed at the end of the first buffer module 412 near the platform 20, and a first weight 414 disposed at the end of the first buffer module 412 away from the platform 20. The second rolling assembly 42 also includes a second buffer module 422, a second roller 423 disposed at the end of the second buffer module 422 near the platform 20, and a second weight 424 disposed at the end of the second buffer module 422 away from the platform 20. When the Z-axis movable frame 47 moves toward the platform 20, causing the first and second rolling assemblies 41 and 42 to contact and apply pressure to the workpiece, the first roller 413 and second roller 423 contact and apply pressure to the workpiece. The amount of pressure applied can be adjusted by adjusting the number of the first and second weights 414 and 424.

[0038] The first buffer module 412 includes a vertical plate fixed to the first movable plate 411, a first mounting plate, and a second mounting plate. The vertical plate is provided with a Z-direction buffer rail. A first weight 414 is provided on the first mounting plate, and a first roller 413 is provided on the second mounting plate. A slider corresponding to the buffer rail is provided on the side of the first mounting plate near the vertical plate, and the slider is slidably connected to the buffer rail. The second mounting plate is provided on the side of the first mounting plate away from the vertical plate. A limit plate is provided on the end of the buffer rail near the carrier 20. Under the action of gravity, the slider slides to the limit plate, that is, the first roller 413 is at the lowest point. When the Z-direction movable frame 47 moves toward the carrier 20 and the first pulley contacts the workpiece to be processed, the workpiece to be processed applies an upward supporting force to the first pulley. This supporting force applies an upward supporting force to the slider through the second mounting plate and the first mounting plate, causing the slider to slide upward, thereby achieving a buffering effect. The structure and buffering method of the second buffer module 422 are the same as those of the first buffer module 412 and will not be repeated here.

[0039] Furthermore, the center positioning mechanism 30 includes a second bracket 33 mounted on one side of the platform 20. A Y-positioning cylinder 31 and an X-positioning clamp 32 are mounted on the side of the second bracket 33 near the platform 20. The Y-positioning cylinder 31 (a side-thrust cylinder) is responsible for positioning the workpiece in the Y direction, while the X-positioning clamp 32 is responsible for positioning and securing the workpiece in the X direction.

[0040] Furthermore, the carrier 20 is arranged on the frame 10. Specifically, the frame 10 is further provided with a third bracket 21, and the carrier 20 is arranged on the frame 10 through the third bracket 21. A sensor 22 is provided on the carrier 20, and the sensor is used to detect whether there is a workpiece to be processed on the carrier 20.

[0041] Furthermore, a synchronous lifting and transferring mechanism 50 is provided on one side of the third bracket 21, that is, the synchronous lifting and transferring mechanism 50 is located below the carrier 20. The synchronous lifting and transferring mechanism 50 includes a transfer bracket 51 that can move in the X direction and a lifting platform 52 that is provided on the transfer bracket 51 and can move in the Z direction. Specifically, the synchronous lifting and transferring mechanism 50 also includes a second guide rail 53, and the transfer bracket 51 is provided on the second guide rail 53. The transfer bracket 51 is slidably connected to the second guide rail 53; the frame 10 is also provided with a transfer motor 54, which is a linear motor. The driving end of the transfer motor 54 is connected to the transfer bracket 51, thereby driving the transfer bracket 51 to move in the X direction. A side plate 55 is provided on one side of the transfer bracket 51, and the lifting platform 52 is provided on the side plate 55. A lifting guide rail 56 is provided on the side of the side plate 55 close to the transfer bracket 51, and the transfer bracket 51 is slidably connected to the lifting guide rail 56. A follower bearing 57 is also provided on the side of the side plate 55 near the transfer bracket 51. A lifting motor 58 is mounted on the transfer bracket 51. A connecting plate 59 is mounted on the output shaft of the lifting motor 58. A slanted plate 591 is mounted on the connecting plate 59, which corresponds to the follower bearing 57. When the lifting motor 58 drives the connecting plate 59 in the X-direction, the connecting plate 59 drives the slanted plate 591 in the X-direction. At this time, the inclined surface of the slanted plate 591 applies an upward force to the follower bearing 57, lifting the side plate 55 and, consequently, the lifting platform 52. A through hole is provided in the carrier 20, through which the lifting platform 52 passes during its vertical movement.

[0042] It should be noted that the lifting platform 52 has three height values. The first height value is that the surface of the lifting platform 52 is lower than the surface of the carrier 20. At this time, it is the initial position of the lifting platform 52; the second height value is that the surface of the lifting platform 52 and the surface of the carrier 20 are on the same horizontal plane, and provide support for the workpiece to be processed; the third height value is that the surface of the lifting platform 52 is higher than the surface of the carrier 20. At this time, the transfer motor 54 drives the transfer bracket 51, the side plate 55 and the lifting platform 52 to move along the X direction to transfer the processed workpiece to the next station. It should be further explained that the processing equipment of the next station is closely connected to the OLED screen rolling machine, and the synchronous lifting and transferring mechanism 50 can transfer the workpiece processed by this process to the next processing equipment.

[0043] Furthermore, vacuum suction cups 61 are provided on both the carrier 20 and the lifting platform 52. The workpiece is adsorbed during the workpiece processing and lifting and transferring process to ensure the position accuracy of the workpiece and a smooth transition during movement, and the workpiece will not move or fall. A first wire clamping jaw 62 along the Y direction and a second wire clamping jaw 63 along the Z direction are provided on the side of the synchronous lifting and transferring mechanism 50 away from the third bracket 21. The first wire clamping jaw 62 is provided on the frame 10, and the second wire clamping jaw 63 is provided on the side panel 55. The first wire clamping jaw 62 and the second wire clamping jaw 63 are used to clamp the wire harness, and the first wire clamping jaw 62 and the second wire clamping jaw 63 work alternately to ensure that the wire harness can be accurately handed over to the lower work station.
