Description

Technical Field

[0001] The utility model belongs to the technical field of diffusion plate production, and in particular relates to a diffusion plate release film attaching device. Background Art

[0002] Light diffusers use chemical or physical means to utilize the physical phenomena of refraction, reflection and scattering that occur when light encounters two media with different refractive indices on its way, thereby changing the path of light and achieving full dispersion of the incident light to produce an optical diffusion effect. Light diffusers are widely used in liquid crystal displays, LED lighting and imaging display systems. During the production process of diffusers, release films need to be attached to them to make the performance of the diffuser stronger.

[0003] At present, the release film of the diffuser plate is attached manually, which is time-consuming and labor-intensive, and the attachment efficiency is too low, which is not conducive to the efficient production of the diffuser plate. At the same time, manual operation makes the diffuser plate easy to slide during the attachment process, resulting in uneven attachment, affecting the production quality of the diffuser plate.

[0004] Therefore, a diffusion plate release film attaching device is needed to solve the problems of low efficiency and uneven attaching of the release film manually in the prior art. Utility Model Content

[0008] It is further worth noting that the inner walls at the front and rear ends of the installation groove are both provided with limiting sliding grooves corresponding to the limiting sliding plates.

[0009] It should be further explained that the output end of the servo motor passes through one side of the installation slot and is fixedly connected to the threaded rod.

[0011] As a preferred embodiment, the two buffer columns both penetrate the bottom of the connecting plate and extend to the center thereof, and the two buffer springs are both fixedly connected between the bottom of the connecting plate and the top of the convex frame.

[0012] As a preferred embodiment, the outer walls of the two smoothing rollers are fixedly connected with soft protective covers.

[0023] Further as Figure 1 and Figure 2 As shown, it is worth explaining in detail that the bottoms of the multiple support columns 2 are fixedly connected with shock-absorbing pads, which play a role in buffering and shock reduction, so that the workbench 1 remains stable throughout the entire attachment process, avoiding the device from being vibrated and causing errors in the film attachment.

[0024] Further as Figure 3 As shown, it is worth explaining in detail that the inner walls of the front and rear ends of the installation groove 6 are provided with limit slide grooves corresponding to the limit slide plate 10, and the limit slide grooves play a role of limiting and guiding the movement of the limit slide plate 10, ensuring that the two limit slide plates 10 can only move stably in the horizontal direction, so that the movement of the hydraulic rod 12 driven by the installation block 9 is more stable.

[0025] Further as Figure 3 As shown, it is worth explaining in detail that the output end of the servo motor 11 passes through one side of the mounting slot 6 and is fixedly connected to the threaded rod 7, ensuring that the servo motor 11 can drive the threaded rod 7 to rotate smoothly, thereby providing driving force for the movement of the hydraulic rod 12 and the leveling mechanism 13.

[0026] According to the above working process, it can be known that: by setting the vacuum generator 3 and the vacuum suction cup 4 to cooperate, the diffusion plate to be laminated is placed on the top of multiple vacuum suction cups 4, and the vacuum generator 3 is turned on so that multiple vacuum suction cups 4 can adsorb and position the diffusion plate to avoid sliding of the diffusion plate during the pasting process, thereby ensuring the stability of the pasting work and improving the production quality of the diffusion plate.

[0027] Further as Figure 4 As shown, it is worth explaining in detail that the leveling mechanism 13 includes a connecting plate 1301 fixedly connected to the bottom of the hydraulic rod 12, and two buffer columns 1302 are slidably connected to the bottom of the connecting plate 1301, and the outer walls of the two buffer columns 1302 are sleeved with buffer springs 1303, and the bottoms of the two buffer columns 1302 are fixedly connected with a convex frame 1304, and the inner walls of the front and rear ends of the convex frame 1304 are rotatably connected to two rotating shafts 1305, and the outer walls of the two rotating shafts 1305 are fixedly connected with leveling rollers 1306.

[0030] This solution has the following working process: in actual use, the diffusion plate to be pasted is placed on the top of multiple vacuum suction cups 4, the vacuum generator 3 is turned on to allow the multiple vacuum suction cups 4 to adsorb and position the diffusion plate, and then the release film is placed on the top of the diffusion plate, the hydraulic rod 12 is turned on to drive the connecting plate 1301 to descend, so that the outer walls of the two smoothing rollers 1306 are in contact with the top of the release film, and then the servo motor 11 is turned on to drive the threaded rod 7 to rotate, so that the ball nut seat 8 drives the mounting block 9 to move, so that the two smoothing rollers 1306 follow the movement, and the two smoothing rollers 1306 roll back and forth on the top of the release film to flatten it. When the film pasting is completed, the vacuum generator 3 is turned off and the diffusion plate can be removed.

[0031] In summary: by setting the servo motor 11, the hydraulic rod 12 and the leveling mechanism 13 in coordination, the outer wall of the two leveling rollers 1306 is fitted with the top of the release film, and then the servo motor 11 is turned on to drive the threaded rod 7 to rotate, so that the two leveling rollers 1306 roll back and forth on the top of the release film to level it, and the entire attachment process is automated, replacing the traditional manual attachment, greatly improving the efficiency of the attachment work; by setting the vacuum generator 3 and the vacuum suction cup 4 in coordination, the diffusion plate to be attached with the film is placed on the top of multiple vacuum suction cups 4, and the vacuum generator 3 is turned on so that the multiple vacuum suction cups 4 can adsorb and position the diffusion plate, thereby preventing the diffusion plate from sliding during the attachment process, ensuring the stability of the attachment work, and improving the production quality of the diffusion plate.
