Description

Technical Field

[0001] This utility model relates to the field of OCA membrane processing, and in particular to an automatic material receiving device for OCA membrane processing. Background Technology

[0002] OCA film, or optically transparent adhesive, is a colorless, transparent, highly adhesive, and weather-resistant specialty adhesive. It is widely used in touchscreens, displays, and optical components to bond transparent optical elements such as lenses and screens, ensuring clarity and stability between these components. OCA film possesses excellent properties such as high light transmittance and water resistance, providing a uniform and transparent adhesive layer that enhances the visual appeal and durability of devices.

[0003] After the OCA film is prepared and cut, an automatic receiving device for OCA film processing is needed to collect the cut OCA film for easy packaging.

[0004] Currently, automatic feeding equipment for OCA film processing typically feeds OCA film directly onto a material plate via a conveyor. However, in actual use, when a portion of the OCA film accumulates on the material plate, the excessive height of the stack can obstruct the feeding point of the conveyor, causing blockage at the automatic feeding point of the OCA film processing equipment. This prevents the OCA film from continuing to be conveyed forward, affecting production efficiency and product quality. Therefore, an automatic feeding device for OCA film processing is proposed to solve the above problems. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an automatic feeding device for OCA membrane processing, which aims to improve the problem of easy clogging at the feeding point of the automatic feeding device for OCA membrane processing in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: an automatic receiving device for OCA film processing, comprising a base, a transmission frame fixedly connected to the top of the base, a transmission machine disposed inside the transmission frame, an anti-tilting component fixedly connected inside the transmission frame to limit the tilting of the OCA film, a side plate fixedly connected to the top of the base, a rotating shaft rotatably connected inside the side plate, a limit plate fixedly connected to the outer periphery of the rotating shaft, a rotating column rotatably connected to the bottom end of the limit plate, a fixed sleeve elastically connected to the outer periphery of the rotating column via a coil spring, a pressure plate fixedly connected to the outer periphery of the rotating column, a roller disposed inside the pressure plate, a fixed disc fixedly connected to the outer periphery of the left end of the rotating shaft, a stop block fixedly connected to the outer periphery of the fixed disc, a Y-shaped bracket connected to a fixed rod at the top of the base, an infrared transmitter fixedly connected to the top of the Y-shaped bracket, an infrared receiver fixedly connected to the top of the Y-shaped bracket, and a holding component fixedly connected to the top of the base.

[0009] As a further description of the above technical solution:

[0010] The transmitter is tilted with the front end lower and the rear end higher.

[0011] As a further description of the above technical solution:

[0012] The anti-tilting component includes a connecting bridge, which is fixedly connected to the inside of the transmission frame on the outside, and an anti-tilting wheel is provided at the bottom of the connecting bridge.

[0013] As a further description of the above technical solution:

[0014] One end of the coil spring is fixedly connected to the outer periphery of the rotating column, and the other end of the coil spring is fixedly connected to the inside of the fixed sleeve. The inner side of the fixed sleeve is fixedly connected to the outer side of the limiting plate.

[0015] As a further description of the above technical solution:

[0019] As a further description of the above technical solution:

[0020] The inner side of the fixing plate is fixedly connected to the outer side of the holding base.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, by setting a rotating shaft and fixing a circular block and other mechanisms, when the OCA film is placed on the holding component, it will push the pressure block upward and drive the stop block to rotate. When the OCA film is placed to a certain height, the stop block will prevent the infrared receiver from receiving the signal, thereby stopping the equipment from working, preventing the OCA film from getting stuck at the feeding port, and ensuring that the feeding is carried out normally.

[0023] 2. In this utility model, by setting up mechanisms such as a circular shaft, a limiting circular block, and a limiting plate, the baffle can be rotated and moved away by removing the fixing pin, so that the neatly stacked OCA film can be easily and completely taken out from the front side of the holding seat, which is more convenient to use.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Reference Figure 1 - Figure 2This utility model provides an embodiment of an automatic receiving device for OCA film processing, comprising a base 1 for supporting and fixing the equipment. A transmission frame 2 for fixed support is fixedly connected to the top of the base 1. A transmission machine 3 is installed inside the transmission frame 2. The transmission machine 3 is inclined with the front end lower and the rear end higher, so that the OCA film has a certain initial velocity after leaving the transmission machine 3. An anti-tilting component is fixedly connected inside the transmission frame 2 to limit the OCA film from tilting. The anti-tilting component includes a connecting bridge 4 for fixed connection. The outer side of the connecting bridge 4 is fixedly connected to the inside of the transmission frame 2. An anti-tilting wheel 5 is provided at the bottom of the connecting bridge 4. Multiple sets of anti-tilting wheels 5 are provided and are located in the middle of the connecting bridge 4. A side plate 6 is fixedly connected to the top of the base 1. Multiple sets of side plates 6 are provided and are symmetrically arranged on the top of the base 1. A rotating shaft 7 is rotatably connected inside the side plate 6. A limiting plate 8 is fixedly connected to the outer periphery of the rotating shaft 7. The limiting plate 8 allows the OCA film with initial velocity to slide forward along the bottom surface of the limiting plate 8.

[0032] Reference Figure 2 - Figure 3 A rotating column 9 is rotatably connected to the bottom end of the limiting plate 8. A fixed sleeve 11 is elastically connected to the outer periphery of the rotating column 9 via a coil spring 10. Two sets of coil springs 10 and fixed sleeves 11 are provided, symmetrically arranged at both ends of the rotating column 9. One end of the coil spring 10 is fixedly connected to the outer periphery of the rotating column 9, and the other end of the coil spring 10 is fixedly connected to the inside of the fixed sleeve 11. When the rotating column 9 is not under force, the coil spring 10 will drive the rotating column 9 to rotate forward. The inner side of the fixed sleeve 11 is fixedly connected to the outer side of the limiting plate 8. A pressure plate 12 is fixedly connected to the outer periphery of the rotating column 9. The pressure plate 12 applies downward pressure to the OCA membrane, making the OCA membranes more tightly packed. Rollers 13 are provided inside the pressure plate 12. Several sets of rollers 13 are arranged front and back inside the pressure plate 12. The rollers 13 can convert sliding friction into rolling friction. Dynamic friction allows the OCA film to slide under the roller 13 at a certain initial velocity. A fixed disk 14 is fixedly connected to the outer periphery of the left end of the rotating shaft 7. A stop block 15 is fixedly connected to the outer periphery of the fixed disk 14. A Y-shaped bracket 16 is connected to the top fixed rod of the base 1. An infrared emitter 17 is fixedly connected to the top of the Y-shaped bracket 16. The infrared emitter 17 can emit a straight infrared light to the right. An infrared receiver 18 is fixedly connected to the top of the Y-shaped bracket 16. The Y-shaped bracket 16 is set as a Y with the top flush. The infrared receiver 18 can receive the emitted infrared light. When the infrared receiver 18 cannot receive the infrared light, it will cut off the power of the equipment and stop the equipment from feeding. The stop block 15 is set between the infrared emitter 17 and the infrared receiver 18. The stop block 15 can block the infrared light emitted by the infrared emitter 17.

[0033] Reference Figure 1 and Figure 4The top of the base 1 is fixedly connected to an OCA film holding assembly for receiving and unloading materials. The holding assembly includes a holding seat 19. The inner wall of the bottom end of the holding seat 19 contacts the bottom end of the roller 13 to compact the OCA film. A round shaft 20 is rotatably connected inside the holding seat 19. A baffle 21 is fixedly connected to the outer periphery of the round shaft 20. The baffle 21 blocks the OCA film, preventing it from sliding to the outside of the holding seat 19. A limiting round block 22 is fixedly connected to the outer periphery of the baffle 21. A fixing pin 24 is slidably connected through the limiting round block 22 and the round shaft 20. A fixing plate 23 is slidably connected to the outer periphery of the fixing pin 24, preventing the round shaft 20 from rotating. The inner side of the fixing plate 23 is fixedly connected to the outer side of the holding seat 19.

[0034] Working principle: To prevent the OCA film from blocking the outlet of the conveyor 3, the OCA film is discharged from the outlet of the conveyor 3, guided by the limiting plate 8, and fed into the bottom inner wall of the holding seat 19. At this time, the OCA film lifts the pressure plate 12 upward, the pressure plate 12 drives the rotating shaft 7 to rotate, the rotating shaft 7 drives the fixed disc 14 to rotate, and the fixed disc 14 drives the stop block 15 to rotate. When the OCA film approaches the transmission port of the conveyor 3, the stop block 15 rotates to be between the infrared receiver 18 and the infrared transmitter 17, blocking the infrared signal. At this time, the equipment stops supplying power. The unloaded OCA film can then be removed to feed more materials. To easily remove the unloaded OCA film, pull out the fixing pin 24 upward. At this time, the shaft 20 can be rotated easily. After rotating the baffle 21 forward, the OCA film can be easily removed from the front side of the holding seat 19.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
