Description

Technical Field

[0001] The invention belongs to the field of liquid crystal glass substrate production, and in particular relates to a paper support film absorption improvement device and a film absorption method thereof. Background Art

[0002] The semi-finished product processing process is an important part of the contemporary LCD glass substrate production process. This process not only undertakes the task of orderly transmitting the glass blocks cut in the previous process, but also ensures that the subsequent process can smoothly receive and further process until the final product is packaged. As a close link between the previous and next processes, the efficiency and stability of the semi-finished product processing process is directly related to the smooth operation of the entire production line. Specifically, the semi-finished product processing process covers a series of delicate and complex processing steps from horizontal cutting, Robot loading, real-time weighing, and longitudinal cutting after the glass flows out of the muffle furnace, to cooling, thickness measurement, automatic detection, manual sampling, and then to sorting and packaging, unloading packaging or direct current. Among them, the packaging operation is the key link of this process, and its efficiency and accuracy directly determine the final quality and output of the product.

[0003] However, in the actual production process, the packaging operation faces many challenges. In particular, when the plate-removing robot removes the substrate from the conveyor belt and the film-applying robot adsorbs the spacer material from the paper support and brings it to the A-frame, if the film position is offset due to static electricity or mechanical failure when the paper support absorbs the spacer material, it will not only seriously affect the production rhythm, but may also cause product waste, and thus have an adverse effect on production and cost. What's more difficult is that due to unfavorable factors such as static electricity carried by the spacer material itself, the paper support often loses film during the adsorption operation. This not only consumes a lot of time and manpower for frequent adjustments to the film support mechanism, but also causes the good products produced by the previous process to be unable to be continuously received by the subsequent process, further exacerbating the cost increase and the decline in production efficiency of the production line.

[0004] Therefore, improving the problems existing in the paper support film absorption method and achieving the goal of stable adsorption without being affected by the static electricity of the spacer material itself has become a technical problem that needs to be solved urgently in the current production of liquid crystal glass substrates. Summary of the invention

[0005] The object of the present invention is to provide a device for improving film absorption of a paper support and a film absorption method thereof, so as to ensure that the paper support is stably absorbed and is not affected by the static electricity of the spacer material itself.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions: In a first aspect, a device for improving film absorption of a paper support platform includes: a first suction cup arranged at the front end of the paper support platform, a second suction cup arranged at the rear end of the paper support platform, a first servo motor, a second servo motor, a vacuum generator, a solenoid valve, and an electrostatic blowing ion rod; The first servo motor is arranged on the front side of the paper supporting platform, the second servo motor is arranged on the rear side of the paper supporting platform, the first servo motor is connected to the first suction cup through transmission, the second servo motor is connected to the second suction cup through transmission, the vacuum generator and the solenoid valve are arranged on the side of the paper supporting platform, the solenoid valve is connected to the vacuum generator, the vacuum generator is connected to the first suction cup and the second suction cup, the electrostatic blowing ion rod is arranged in front of the paper supporting platform, and is located on the same side of the paper supporting platform as the first servo motor.

[0007] In some embodiments, the first servo motor is a rotary servo motor.

[0008] In some embodiments, the height of the electrostatic ionizing bar is less than or equal to the height of the paper support platform.

[0009] In some embodiments, the air control box is installed on a side of the paper support table, and the vacuum generator and the solenoid valve are installed inside the air control box.

[0010] In some embodiments, the two air control boxes respectively control the adsorption and disconnection of the first suction cup and the second suction cup.

[0011] In some embodiments, a connecting rod is disposed between the first suction cup and the second suction cup, one end of the connecting rod is connected to the first suction cup, and the other end of the connecting rod is connected to the second suction cup.

[0012] In some embodiments, the diameter of the first suction cup and the second suction cup is 25 mm.

[0013] In a second aspect, a film absorbing method is provided, using the above-mentioned device for improving the film absorbing of a paper support, comprising the following steps: After the first servo motor controls the first suction cup to descend to the front suction position, and the second servo motor controls the second suction cup to descend to the rear suction position, After the electromagnetic valve controls the vacuum generator to make the first suction cup and the second suction cup adsorb the two ends of the spacer material, the first servo motor and the second servo motor control the first suction cup and the second suction cup to rise to a preset position, The electrostatic blowing ion rod is used to blow and separate the middle part of the spacer material to complete the film absorption separation.

[0014] In some embodiments, the first servo motor is a rotary servo motor. After the first servo motor controls the first suction cup to rise to a preset position, it rotates 30° to 45° toward the rear of the paper support table.

[0015] In some embodiments, the first suction cup and the second suction cup continue to adsorb the two ends of the spacer material simultaneously.

[0016] Compared with the prior art, the present invention has the following beneficial effects: The present invention provides a device for improving the film absorption of a paper support table. By respectively arranging a first suction cup and a second suction cup at the front end and the rear end of the paper support table, both ends of the spacer material can be adsorbed at the same time, effectively reducing the contact area between the spacer materials, and blowing with an electrostatic blowing ion rod to blow and separate the middle part of the spacer material. During the continuous bag collection operation of the production line, the paper support table can stably absorb the spacer material and ensure that the spacer material is not affected by its own static electricity, thereby reducing the frequency of film falling, thereby improving production efficiency and avoiding unnecessary good products.

[0017] Furthermore, the present invention arranges a connecting rod between the first suction cup and the second suction cup, so that a stable connection structure is formed between the first suction cup and the second suction cup, thereby enhancing the stability and reliability of the entire device and ensuring that the front and rear cylinders rise or fall synchronously.

[0018] In the film suction method provided by the present invention, after the first servo motor controls the first suction cup to rise to a preset position, it rotates 30°~45° toward the rear of the paper support table, which can reduce the contact area between the spacer materials, and then the electrostatic blowing ion rod is used to blow and separate them, which can optimize the separation effect of the spacer materials.

For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0024] The embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0025] like Figure 1 As shown, this embodiment provides a device for improving the film absorption of a paper support, including a first suction cup 1, a second suction cup 2, a first servo motor, a second servo motor, a vacuum generator, a solenoid valve, an electrostatic blowing ion rod 4, a connecting rod 5 and an air control box 6; The first servo motor adopts a rotary servo motor; the first suction cup 1 and the second suction cup 2 are new material suction cups with a diameter of 25 mm. The suction cups have good air permeability and adsorption properties, and the adsorption force is uniform.

[0026] A total of 9 first suction cups 1 are provided, and are arranged in parallel at the front end of the paper support platform 3; a total of 4 second suction cups 2 are provided, and are arranged in parallel at the rear end of the paper support platform 3; The rotary servo motor is arranged at the front side of the paper support platform 3, the second servo motor is arranged at the rear side of the paper support platform 3, the rotary servo motor is connected to the first suction cup 1 by transmission, and the second servo motor is connected to the second suction cup 2 by transmission. The air control box 6 is installed on the side of the paper support table 3, and the vacuum generator and the electromagnetic valve are installed inside the air control box 6. The electromagnetic valve controls the vacuum generator to achieve the function of air source adsorption and disconnection. Two air control boxes 6 are set and arranged side by side on the same side of the paper support table 3. The air control boxes 6 control the adsorption and disconnection of the first suction cup 1 and the second suction cup 2 respectively.

[0027] The vacuum generator and the solenoid valve are arranged on the side of the paper support table 3, the solenoid valve is connected to the vacuum generator, the vacuum generator is connected to the first suction cup 1 and the second suction cup 2, the electrostatic blowing ion rod 4 is arranged in front of the paper support table 3, and is located on the same side of the paper support table 3 as the rotary servo motor.

[0028] The height of the electrostatic blowing ion rod 4 is less than or equal to the height of the paper support platform 3 .

[0029] A connecting rod 5 is disposed between the first suction cup 1 and the second suction cup 2 , one end of the connecting rod 5 is connected to the first suction cup 1 , and the other end of the connecting rod 5 is connected to the second suction cup 2 .

[0030] This embodiment also provides a film absorbing method based on the above-mentioned paper support film absorbing improvement device, comprising the following steps: After the first suction cup 1 is controlled to descend to the front suction position by the rotating servo motor, and the second suction cup 2 is controlled to descend to the rear suction position by the second servo motor, The solenoid valve controls the vacuum generator to make the first suction cup 1 and the second suction cup 2 adsorb the two ends of the spacer material to reduce the contact area between the spacer materials. After the first suction cup 1 and the second suction cup 2 are raised to a preset position by the rotary servo motor and the second servo motor, the first suction cup 1 is raised to a preset position by the rotary servo motor and then rotated 30° to 45° toward the rear of the paper support table. Since the surface area of ​​the spacer material is large, after the device is lifted to a certain position after adsorption, a small part of the spacer material is still in contact with the next spacer material. The electrostatic ion rod 4 is used to blow air to separate the two spacer materials to complete the film absorption separation.

[0031] Specifically, as the rotary servo motor descends to absorb the film, the second servo motor descends synchronously and simultaneously performs the film absorbing action. The rotary servo motor moves in front of the paper support table, and the servo motor moves behind the paper support table, simultaneously but differently.

[0032] The device for improving the film absorption of the paper support provided in this embodiment can ensure that the adsorption of the paper support is stable when the production line is continuously receiving packages, and the film drop frequency will be significantly reduced, thereby improving the production efficiency of the production line and avoiding unnecessary good products. If this device is not considered and the original device is still used, the adsorption stability of the paper support will be uncontrollable, resulting in package losses. After the device is installed, the adsorption stability of the paper support is guaranteed, the film drop frequency is close to zero, and the output of good products is increased.

[0033] It is known from common technical knowledge that the present invention can be implemented by other embodiments that do not deviate from its spirit or essential features. Therefore, the above disclosed embodiments are only illustrative in all respects, not exclusive, and all changes within the scope of the present invention or equivalent to the scope of the present invention are included in the present invention.
