Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of tape defoaming, and specifically relates to a vacuum pressure defoaming device for tapes. Background Art
[0002] In recent years, with the rapid development of industries such as electronics, optoelectronics, automotive, and medical, the demand for adhesive materials such as tapes has increased sharply. During the manufacturing process of electronic products such as smartphones, tablets, and laptops, the lamination of key components such as display screens and touchscreens requires extremely high precision and flatness. The presence of bubbles in the tape will seriously affect the display effect and user experience. During the manufacturing process of optoelectronic products such as optical components, LED packaging, and solar panels, there are also high requirements for the lamination precision and flatness of materials. Tape bubbles will cause a decline in optical performance and even damage components.
[0003] Some special types of tapes (such as high-temperature tapes, conductive tapes, etc.) may be more likely to generate bubbles during the lamination process. On components with complex or uneven surfaces that need to be laminated, bubbles are more likely to generate and difficult to eliminate. The presence of bubbles will reduce the adhesion between the tape and the material, increasing the risk of cracking and peeling during product use. Therefore, it is necessary to eliminate the bubbles in the laminated tape during the manufacturing process.

However, these methods are often inefficient and difficult to ensure the complete elimination of bubbles, unable to meet the requirements of high-precision production.

Specific embodiments
[0037] To make the objectives, technical solutions and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some but not all of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0038] In this application, the orientation or positional relationship indicated by terms such as "upper", "inner", "outer", "middle", etc. is based on the orientation or positional relationship shown in the accompanying drawings. These terms are mainly used to better describe this application and its embodiments, and are not used to limit that the indicated devices, elements or components must have a specific orientation or be constructed and operated in a specific orientation.
[0039] A vacuum pressure defoaming device for tape, comprising a box body 1, and a plurality of support legs 2 are evenly connected to the lower end of the box body 1; a plurality of brake universal wheels 3 are evenly connected to the lower end of the box body 1. A vacuum furnace 4 is installed in the box body 1, and an opening 5 is provided in the box body 1 corresponding to the vacuum furnace 4. A sealing door 6 is arranged at the opening 5, and the sealing door 6 is rotatably connected to the box body 1. A safety door 7 is rotatably connected to the box body 1 corresponding to the sealing door 6; thus, the sealing door 6 and the safety door 7 provide double protection for the defoaming work, ensuring the sealing performance of the vacuum furnace 4 during the working process and avoiding accidental touch during the working process. The vacuum furnace 4 is communicated with a vacuum pump assembly 8, and the vacuum pump assembly 8 is connected inside the box body 1. An installation door 16 is rotatably connected to one side of the box body 1 corresponding to the vacuum pump assembly 8. Thus, the internal structure of the box body 1 can be repaired and replaced through the installation door 16, ensuring the stability of the operation of the entire device. A plurality of air holes 9 are evenly arranged on the inner side wall of the vacuum furnace 4, and heating wires 10 are arranged between the air holes 9. The heating wires 10 are embedded inside the side wall of the vacuum furnace 4; ensuring the uniformity and efficiency of the heating and defoaming processes. While the vacuum pump assembly 8 is working, the heating wires 10 start to heat up, and the heat is transferred to the inside of the vacuum furnace 4 through heat conduction, further helping the bubbles in the tape to burst and discharge. A plurality of placement plates 11 are slidably connected inside the vacuum furnace 4. A sliding track 12 is connected to the inner wall of the vacuum furnace 4 corresponding to the placement plates 11, and a rotating handle 15 is connected to the end of the placement plate 11. A stop block 13 is rotatably connected to the front end of the sliding track 12. Thus, the placement plate 11 is slid out of the vacuum furnace 4 along the sliding track 12 by rotating the handle 15, and the product to be processed is placed on the placement plate 11. Then, the placement plate 11 is pushed back into the vacuum furnace 4, and the stop block 13 is rotated to the locked state. The sealing door 6 is closed to press against the stop block 13, and thus the baffle fixes the position of the placement plate 11. Then, the sealing door 6 and the safety door 7 are closed, ensuring the stability of the placement plate 11 during the defoaming process. A concave handle 14 is provided on the stop block 13. Thus, the convenience of operation is increased.
[0040] A gas flow meter 17, a furnace pressure gauge 18 and a furnace temperature gauge 19 are connected to the box body 1. Thus, the data inside the vacuum furnace 4 can be provided in real time, and the vacuum degree, temperature and pressure during the defoaming process can be accurately controlled. Problems can also be discovered in time, ensuring the stability of the production process.
[0041] An exhaust gas purification device is connected to the outside of the box body 1. The exhaust gas purification device is communicated with the vacuum pump assembly 8. The exhaust gas purification device includes an air pipe 20. A filtering component 21 and a catalytic component 22 are connected inside the air pipe 20. An exhaust fan 23 is connected to the outlet position of the air pipe 20. Furthermore, the tape releases volatile organic compound exhaust gas through heating. The exhaust gas extracted by the vacuum pump assembly 8 enters the exhaust gas purification device. Then the gas first passes through the filtering component 21 in the air pipe 20 to filter out the macromolecular pollutants in the exhaust gas. Then the gas enters the catalytic component 22. The gas undergoes a chemical reaction with the harmful gas under the action of the catalyst and is converted into low-pollution gas. Then the gas is discharged under the action of the exhaust fan 23, ensuring the working environment, reducing the risk of the staff inhaling harmful gas, and increasing the production safety. The air pipe 20 is detachably connected to the box body 1. Furthermore, it is convenient to replace the exhaust gas purification device, and it can be adjusted and optimized according to different production requirements to meet the requirements of different products.
[0042] The working process of the present utility model is as follows:
[0043] First, slide the placement plate 11 out of the vacuum furnace 4 along the sliding track 12 by rotating the handle 15, place the product to be processed on the placement plate 11, then push the placement plate 11 back into the vacuum furnace 4, and rotate the stop block 13 to the locked state. Close the sealing door 6 to press against the stop block 13, and then close the sealing door 6 and the safety door 7. Start the vacuum pump assembly 8. The vacuum pump assembly 8 extracts the gas inside the vacuum furnace 4, gradually reducing the pressure inside the furnace. At this time, the furnace pressure gauge 18 shows the change of the pressure inside the furnace in real time, and the gas flowmeter 17 can monitor the gas flow during the air extraction process.
[0044] While the vacuum pump assembly 8 is working, the heating wire 10 starts to heat up, and transfers the heat to the inside of the vacuum furnace 4 through heat conduction, further helping the bubbles in the tape to burst and discharge. At this time, the furnace temperature gauge 19 monitors the temperature inside the vacuum furnace 4 in real time.
[0045] Among them, the exhaust gas extracted by the vacuum pump assembly 8 enters the exhaust gas purification device. Then the gas first passes through the filtering component 21 in the air pipe 20 to filter out the macromolecular pollutants in the exhaust gas. Then the gas enters the catalytic component 22. The gas undergoes a chemical reaction with the harmful gas under the action of the catalyst and is converted into low-pollution gas. Then the gas is discharged under the action of the exhaust fan 23.
[0046] When the pressure and temperature inside the vacuum furnace 4 reach the preset values and are maintained for a certain period of time, the defoaming process is completed. Then turn off the device. After the vacuum furnace 4 cools down to a safe temperature, open the safety door 7 and the sealing door 6. Rotate the stop block 13 by the concave handle 14, and slide the placement plate 11 out of the vacuum furnace 4 by rotating the handle 15 to take out the processed product.
