Description

Technical Field

[0001] This utility model relates to the field of bonding machine technology, and in particular to a polarizer bonding machine. Background Technology

[0002] With the continuous development of display technology, flat panel display devices such as liquid crystal displays (LCDs) and organic light-emitting diode displays (OLEDs) are playing an increasingly important role in our daily lives. One of the core components of these display devices is the polarizer, which can improve the display effect by selectively allowing or blocking light from specific directions.

[0003] In the past, polarizer application mainly relied on manual operation or semi-automated equipment. However, this method has the following drawbacks: manual operation makes it difficult to ensure that each polarizer is applied to the designated position with extremely high precision, especially when dealing with displays with small size or high-density pixels, where the lack of precision is particularly prominent; at the same time, manual operation is slow and cannot meet the needs of large-scale production, which limits the overall capacity of the production line and leads to low efficiency; in addition, due to the influence of human factors, problems such as bubbles and wrinkles are prone to occur during the application process, resulting in unstable product quality.

[0004] Therefore, it is necessary to design a polarizer attachment machine to solve the above-mentioned technical problems. Utility Model Content

[0005] To overcome the three major problems of relying on manual or semi-automatic equipment for polarizer application: difficulty in ensuring high-precision application (especially for small-sized or high-density pixel displays), slow speed leading to limited production capacity, and human factors causing bubbles and wrinkles that affect quality, this utility model provides a polarizer application machine.

[0006] The technical implementation scheme of this utility model is as follows: A polarizer attaching machine includes a support frame, a first conveying component, a second conveying component, a limiting plate, a top shell, an electric turntable, an electric push rod, a connecting frame, sliding rods, return springs, connecting plates, and electric suction cups. The first conveying component is installed on the top left side of the support frame, and the second conveying component is installed on the top right side of the support frame. Limiting plates are fixedly connected to both the left and right sides of the first and second conveying components. The top shell is fixedly connected between the left and right sides of the top of the support frame. An electric turntable is installed in the middle of the top of the support frame. An electric push rod is installed on the top of the electric turntable. The telescopic rod of the electric push rod is connected to the connecting frame. Sliding rods are slidably connected to the left and right sides of the bottom of the connecting frame. Return springs are sleeved between the sliding rods and the connecting frame. A connecting plate is fixedly connected to the bottom of each of the two sliding rods. Multiple electric suction cups are installed at the bottom of each of the two connecting plates.

[0007] Optionally, the first conveying assembly is used to transport the object to be attached, and the second conveying assembly is used to transport the polarizer. The first conveying assembly and the second conveying assembly transport in opposite directions.

[0008] Optionally, the suction cup portion of the motorized suction cup is made of rubber.

[0009] Optionally, it also includes a limit frame, a baffle, a guide rod, and a return spring. The two connecting plates are fixedly connected to the ends of the plates that are far apart from each other. The bottom left and right sides of the two limit frames are slidably connected to guide rods. A baffle is fixedly connected between the bottom of each set of guide rods. A return spring is sleeved between the baffle and the guide rod.

[0010] Optionally, the baffle is made of aluminum alloy.

[0011] Optionally, it also includes an electric push rod II, a connecting frame II, an electric slide rail, an electric slider, and a compaction roller. An electric push rod II is fixedly connected to the rear left side of the top of the top shell. The telescopic rod of the electric push rod II is connected to the connecting frame II. An electric slide rail is fixedly connected to the left and right sides of the bottom of the connecting frame II. An electric slider is slidably connected to both electric slide rails. A compaction roller is connected between the two electric sliders. The compaction roller is located behind the first conveying assembly.

[0012] Optionally, the compaction roller is made of carbide.

[0013] The beneficial effects are: 1. Through the precise control of components such as electric turntable and electric push rod, this utility model can achieve precise positioning and attachment of polarizer and object to be attached, reducing errors caused by manual operation, improving product quality consistency, and the return spring design not only ensures buffering during descent, but also ensures stability during ascent, avoiding damage to polarizer or object to be attached.

[0014] 2. This utility model provides good adsorption force by using a rubber electric suction cup, ensuring that the polarizer will not shift or fall off during transportation. In addition, the combination design of the baffle and return spring can flexibly adjust the pressure distribution according to the irregularity of the object surface, thereby applying uniform pressure to the entire bonding surface and further improving the bonding quality.

[0015] 3. This utility model uses the electric slide rail and electric slider to make the compaction roller roll on the entire surface of the polarizer for further compaction. The compaction roller is made of hard alloy material, which can apply uniform pressure to the polarizer after the application is completed, ensuring that it is tightly attached to the surface of the object to be applied.

[0016] 4. This utility model provides overall protection for the equipment through the top shell, and helps maintain the cleanliness of the internal environment, preventing dust and other impurities from entering the equipment and affecting its working performance, while also protecting the safety of the operators.

[0017] 5. This utility model greatly reduces the time and complexity of manual operation through automated material conveying and a precise positioning system (including components such as electric push rods, connecting frames, and sliding rods). The first and second conveying components can efficiently transport the object to be attached and the polarizing film to the designated position, thus speeding up the entire production process.

Detailed Implementation

[0026] Example: A polarizer attaching machine, such as Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 and Figure 7 As shown, the assembly includes a support frame 1, a first conveying assembly 2, a second conveying assembly 3, a limiting plate 4, a top shell 5, an electric turntable 6, an electric push rod 7, a connecting frame 8, a sliding rod 9, a return spring 10, a connecting plate 11, and an electric suction cup 12. The first conveying assembly 2 is installed on the top left side of the support frame 1, and the second conveying assembly 3 is installed on the top right side of the support frame 1. The first conveying assembly 2 is used to transport the object to be attached, and the second conveying assembly 3 is used to transport the polarizing film. The first conveying assembly 2 and the second conveying assembly 3 transport in opposite directions. Both the left and right sides of the first conveying assembly 2 and the second conveying assembly 3 are connected by screws. The support frame 1 is equipped with a limit plate 4 and a top shell 5 is installed between the left and right sides of the top of the support frame 1 by screws. An electric turntable 6 is installed in the middle of the top of the support frame 1. An electric push rod 7 is installed on the top of the electric turntable 6. The telescopic rod of the electric push rod 7 is connected to a connecting frame 8. Sliding rods 9 are slidably connected to the left and right sides of the bottom of the connecting frame 8. A return spring 10 is sleeved between the sliding rod 9 and the connecting frame 8. A connecting plate 11 is installed at the bottom of each of the two sliding rods 9 by screws. Multiple electric suction cups 12 are installed at the bottom of each of the two connecting plates 11. The suction cup part of the electric suction cup 12 is made of rubber.

[0027] like Figure 3 , Figure 6 and Figure 7 As shown, it also includes a limit frame 13, a baffle 14, a guide rod 15, and a return spring 16. The two connecting plates 11 are mounted with limit frames 13 at their ends that are far apart from each other. The bottom left and right sides of the two limit frames 13 are slidably connected to guide rods 15. The bottom of each set of guide rods 15 is mounted with a baffle 14 by screws. A return spring 16 is sleeved between the baffle 14 and the guide rod 15. The baffle 14 is made of aluminum alloy.

[0028] like Figure 3 and Figure 4 As shown, it also includes an electric push rod 17, a connecting frame 18, an electric slide rail 19, an electric slider 20, and a compaction roller 21. The electric push rod 17 is installed on the rear left side of the top of the top shell 5 by screws. The telescopic rod of the electric push rod 17 is connected to the connecting frame 18. An electric slide rail 19 is installed on the left and right sides of the bottom of the connecting frame 18 by screws. An electric slider 20 is slidably connected to both electric slide rails 19. A compaction roller 21 is connected between the two electric sliders 20. The compaction roller 21 is located behind the first conveying component 2 and is made of hard alloy material.

[0029] When the device is needed, the operator first turns on the power and starts the preset control program. Then, the object to be attached is placed on the first conveying assembly 2, and the polarizing film is placed on the second conveying assembly 3. The limiting plate 4 is used to fix and guide the transported materials to ensure their stability during transmission. The first conveying assembly 2 and the second conveying assembly 3 start working, respectively conveying the object to be attached and the polarizing film to the designated positions. The electric push rod 7 drives the connecting frame 8 to descend, so that the electric suction cup 12 contacts and adsorbs the polarizing film. The suction cup part of the electric suction cup 12 is made of rubber to ensure good adsorption force. Then, the electric push rod 7 drives the connecting frame 8 to rise, lifting the polarizing film from the second conveying assembly 3. During the alignment process, the limiting frame 13 and the guide rod 15 ensure the stability of the connecting plate 11 and the electric suction cup 12, avoiding any unnecessary shaking that would affect the attachment accuracy. If necessary, the electric turntable 6 rotates 180° to align the polarizing film with the object to be attached. Then... Electric push rod 7 descends again, accurately attaching the polarizer to the object to be attached. As the polarizer approaches the object, baffle 14 slides down along guide rod 15. Due to the presence of return spring 16, baffle 14 can flexibly adjust its position according to the irregularity of the object's surface, thus ensuring uniform pressure is applied across the entire attachment surface. Baffle 14 is made of aluminum alloy, which is both lightweight and sturdy. After the initial attachment is completed, electric push rod 17 drives connecting frame 18 to move downward, causing compaction roller 21 to press onto the attached polarizer, ensuring a tight fit. Then, electric slide rail 19 and electric slider 20 work together to make compaction roller 21 roll across the entire surface of the polarizer, further compacting it. Compaction roller 21 is made of hard alloy, which can apply uniform pressure to the polarizer after attachment, ensuring a tight fit against the object's surface. Top shell 5 provides overall protection for the equipment and helps maintain the cleanliness of the internal environment. After attachment is completed, all components are reset, ready for the next round of operation.
