[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means a limitation on the utility model and its application or use. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0027] like Figure 1 As shown, an embodiment of the utility model provides a film surface texture processing device, which includes a processing platform 10, a lower roller 20, an upper roller 30 and a driving mechanism 40. The lower roller 20 is rotatably arranged on the processing platform 10, and the rotation axis of the lower roller 20 extends in the transverse direction. The upper roller 30 is rotatably arranged on the processing platform 10 and is located above the lower roller 20. The rotation axis of the upper roller 30 is parallel to the rotation axis of the lower roller 20. There is a film pressing gap between the upper roller 30 and the lower roller 20. The driving mechanism 40 is arranged on the processing platform 10, and the driving mechanism 40 can drive the upper roller 30 and the lower roller 20 to rotate synchronously in opposite directions, wherein the outer side wall of one of the upper roller 30 and the lower roller 20 has a texture processing portion.
[0028] The film surface texture processing equipment provided in this embodiment is applied, and the film surface texture processing equipment includes a processing platform 10, a lower roller 20, an upper roller 30 and a driving mechanism 40. The driving mechanism 40 is used to drive the upper roller 30 and the lower roller 20 to rotate synchronously in opposite directions, and the film 51 is sent into the film pressing gap between the upper roller 30 and the lower roller 20, so that the texture processing part is used to press out texture on one side surface of the film 51. When the film 51 is attached to the side of the sealing layer 52 away from the PCB board 54, the side of the film 51 with the pressed texture is placed away from the PCB board 54, and the texture on the film 51 is used to avoid reflection of the film 51, thereby improving the display effect of the LED display module.
[0029] Furthermore, using film surface texture processing equipment to process the surface of the film 51 has the advantages of low processing cost, simple process, controllable stability, low processing difficulty and short time consumption.
[0030] It should be noted that the synchronous and skewed rotation of the upper roller 30 and the lower roller 20 means that the rotation directions of the upper roller 30 and the lower roller 20 are opposite, and the rotation linear speeds of the outer edges of the upper roller 30 and the lower roller 20 are the same.
[0031] In this embodiment, the texture processing portion includes a plurality of texture grooves. When the film 51 is fed into the lamination gap between the upper roller 30 and the lower roller 20, the upper and lower surfaces of the film 51 are squeezed by the upper roller 30 and the lower roller 20 respectively, so that part of the film 51 is pressed into the plurality of texture grooves, thereby forming textures on the surface of the film 51 that match the plurality of texture grooves.
[0032] In this embodiment, a plurality of texture grooves are arranged on the outer side wall of the upper roller 30, and the plurality of texture grooves are evenly distributed on the outer side wall of the upper roller 30. The even distribution of the plurality of texture grooves on the outer side wall of the upper roller 30 means that the distribution density of the plurality of texture grooves at various locations on the outer side wall of the upper roller 30 is the same, so that after the film 51 is fed into the film pressing gap between the upper roller 30 and the lower roller 20 and is squeezed, uniform textures can be formed on the surface of the film 51, thereby improving the uniformity of the texture on the surface of the film 51 and avoiding the problem of uneven color of the film 51.
[0033] Specifically, the plurality of grooves are formed by chemically corroding the outer wall of the upper roller 30 .
[0034] In this embodiment, the depths of the multiple grooves are the same, so that after the film 51 is fed into the film pressing gap between the upper roller 30 and the lower roller 20 and squeezed, grooves of the same height can be formed on the surface of the film 51, thereby improving the uniformity of the grooves on the surface of the film 51 and avoiding problems such as color unevenness of the film 51.
[0035] In this embodiment, the outer side wall of the other one of the upper roller 30 and the lower roller 20 is a smooth structure. Therefore, after the film 51 is fed into the film pressing gap between the upper roller 30 and the lower roller 20 and is squeezed, one side of the surface of the film 51 is pressed with textures by the texture processing part, while the other side of the film 51 is pressed smooth and flat, thereby improving the flatness and laminating reliability of the film 51 when it is attached to the side of the sealing layer 52 away from the PCB board 54.
[0036] In this embodiment, the film surface texture processing equipment further includes a gap adjustment structure, which is disposed between the upper roller 30 and the lower roller 20. The gap adjustment structure can adjust the size of the film pressing gap in the vertical direction. By adjusting the size of the film pressing gap in the vertical direction using the gap adjustment structure, the texture pressing requirements of films 51 with different thickness requirements can be met.
[0037] In this embodiment, the processing platform 10 includes a platform base 11 and a mounting frame 12, the mounting frame 12 is arranged on the upper surface of the platform base 11, the upper roller 30 is rotatably arranged on the mounting frame 12 around its axis, the lower roller 20 is rotatably arranged on the mounting frame 12 around its axis, and the upper roller 30 and / or the lower roller 20 are adjustably arranged on the mounting frame 12 in the up and down directions.
[0038] In this embodiment, the gap adjustment structure includes a strip hole, a support shaft and a nut. The strip hole is set on the mounting frame 12 and extends in the up-down direction. The end of the support shaft passes through the strip hole and is provided with a threaded connection section. The support shaft is adjustably arranged in the strip hole along the extension direction of the strip hole. The upper roller 30 is rotatably sleeved on the support shaft. The nut is sleeved on the threaded connection section. The end of the nut facing the upper roller 30 can abut against the mounting frame 12 to fix the support shaft. The above-mentioned gap adjustment structure makes the size adjustment structure of the film pressing gap in the up-down direction simple, low-cost and easy to operate.
[0039] In this embodiment, the driving mechanism 40 includes a driving motor and a transmission member, the transmission member has an input part and two output parts, the output shaft of the driving motor is drivingly connected to the input part of the transmission member, and the two output parts of the transmission member are drivingly connected to the upper roller 30 and the lower roller 20 respectively. The driving mechanism 40 with the above structure can improve the synchronization of the synchronous and unidirectional rotation of the upper roller 30 and the lower roller 20, so that after the film 51 is fed into the film pressing gap between the upper roller 30 and the lower roller 20, the film 51 can be subjected to uniform extrusion force, improve the uniformity of the texture on the surface of the film 51, and avoid the problem of uneven color of the film 51.
[0040] In this embodiment, the transmission member includes a driving gear and two driven gears, the driving gear is sleeved on the output shaft of the driving motor, and the two driven gears are respectively arranged at the ends of the upper roller 30 and the lower roller 20, and the two driven gears are meshed with the driving gear. The single input torque is decomposed into two output torques by gear transmission, so as to realize the driving of the upper roller 30 and the lower roller 20, and the size adjustment range of the film pressing gap between the upper roller 30 and the lower roller 20 in the vertical direction does not affect the meshing between the two driven gears and the driving gear.
[0041] In other embodiments, the driving mechanism 40 includes two motors and two transmission members, the transmission members include a driving pulley, a driven pulley and a transmission belt, the two driving pulleys are respectively mounted on the motor shafts of the two motors, one driven pulley is arranged at one end of the upper roller 30, and the other driven pulley is arranged at one end of the lower roller 20, one transmission belt is mounted on one of the driving pulleys and one of the driven pulleys, and the other transmission belt is mounted on the other driving pulley and the other driven pulley. After the size of the film pressing gap between the upper roller 30 and the lower roller 20 in the up-down direction is adjusted, two independent motors and transmission members can be used to provide independent driving forces for the upper roller 30 and the lower roller 20, respectively, so as to avoid affecting the driving mechanism 40 on the upper roller 30 and the lower roller 20.
[0042] When using the film surface texture processing equipment provided in this embodiment, the gap adjustment structure is first used to adjust the size of the film pressing gap in the up and down directions so that the size of the film pressing gap in the up and down directions meets the target thickness of the film 51 after pressing. The driving mechanism 40 is started to drive the upper roller 30 and the lower roller 20 to rotate synchronously in opposite directions, and the film 51 is sent into the film pressing gap between the upper roller 30 and the lower roller 20. The upper surface of the film 51 is pressed with texture by the texture processing part arranged on the upper roller 30, and the lower surface of the film 51 is pressed flat by the smooth outer wall of the lower roller 20.
[0043] It should be noted that the steps of attaching the pressed film 51 to the side of the sealing layer 52 away from the PCB board 54 are as follows: place the LED display module that has completed the GOB sealing process flat on the film sticking platform, blow air to the surface of the LED display module to clean the surface of the LED display module, heat the LED display module to 80°C until the surface of the sealing layer 52 away from the PCB board 54 is softened, and lay the pressed film 51 on the surface of the sealing layer 52 away from the PCB board 54, use a roller to roll back and forth to drive out the bubbles between the film 51 and the sealing layer 52, place the LED display module upside down on the film sticking platform (that is, the light-emitting surface of the LED display module faces downward), and apply 30 kg of pressure on the LED display module, hold for 8 seconds, let it stand for 8 hours, wait for the sealing layer 52 to harden again, cut off the excess film 51 at the edge of the LED display module, and then complete the construction.
[0044] During this process, there is no need to evacuate the film or wait for UV curing. The film pasting operation is relatively simple and only requires flat and even application.
[0045] like Figure 2 As shown, the LED display module after film affixing includes a bottom shell 55, a PCB board 54, lamp beads 53, a sealing layer 52 and a film 51, wherein the PCB board 54 is installed on the front side of the bottom shell 55, the lamp beads 53 are arranged on the front side of the PCB board 54 and protrude from the PCB board 54, the sealing layer 52 is a glue layer formed by a GOB sealing process and is located on the front side of the PCB board 54 and wraps the lamp beads, and the film 51 is attached to the side of the sealing layer 52 away from the PCB board 54, and the side of the film 51 with pressed patterns is placed away from the PCB board 54.
[0046] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
