Description

Technical Field

[0001] This invention relates to the field of TP membrane cleaning technology, and in particular to TP membrane cleaning equipment. Background Technology

[0002] TP, short for touchscreen, is mainly used in electronic products, and most are now flexible TP films. During the production process, large particles of dust and oil accumulate on the surface of the TP film, affecting the subsequent bonding effect. Therefore, its top and bottom surfaces need to be cleaned. In practice, alcohol is usually used first, followed by petroleum ether, for cleaning. However, because the TP film is relatively dry before cleaning, the wetting ability of alcohol is insufficient, making it difficult to remove contaminants completely during wiping. Therefore, we propose a TP film cleaning device to solve this problem. Summary of the Invention

[0003] In view of this, the present invention addresses the deficiencies of the prior art, and its main objective is to provide a TP membrane cleaning device, which solves the aforementioned problems.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: TP membrane cleaning equipment includes a body, on which a discharge roll is provided, and a set of conveying rollers arranged sequentially along the material conveying direction, a water wetting device for wetting the upper and lower surfaces of the TP membrane, an alcohol cleaning device for cleaning the upper and lower surfaces of the TP membrane, a petroleum ether cleaning device for cleaning the upper and lower surfaces of the TP membrane, and a receiving roll for receiving the material.

[0005] As a preferred embodiment, the water wetting device includes a first support frame, a first mounting frame, and two wetted cotton boards. The first support frame is mounted on the machine body. The left and right ends of the first mounting frame are respectively provided with vertically extending first tracks. Two front-to-back extending support rods are slidably mounted on each first track. Each wetted cotton board has front-to-back extending mounting holes on both its left and right sides. The mounting holes on the left and right sides of each wetted cotton board are respectively fitted onto the corresponding support rods in the front-to-back direction. Opening and closing cylinders are also provided on the left and right sides of the first mounting frame. The two driving parts of each opening and closing cylinder are respectively connected to the two corresponding support rods, thereby driving the two support rods to move relative to each other, and thus driving the wetted cotton boards to open and close in the vertical direction.

[0006] As a preferred embodiment, the alcohol cleaning device includes an alcohol tank into which the TP film is immersed and passes, and a first wiping component for wiping and cleaning the TP film in the alcohol tank.

[0007] As a preferred embodiment, the alcohol cleaning device further includes a second support frame, a second mounting frame, and a third mounting frame. The second mounting frame extends laterally and is mounted on the second support frame. The left and right ends of the second mounting frame are respectively provided with first clamping mechanisms for clamping the left and right edges of the TP film. The third mounting frame extends laterally and is mounted on the second support frame. The left and right ends of the third mounting frame are respectively provided with second clamping mechanisms for clamping the left and right edges of the TP film. The first wiping assembly consists of two sets, which are arranged vertically opposite each other on the third mounting frame. Each set of the first wiping assembly includes two swing arms and a swing drive mechanism for driving the two swing arms to open and close back and forth in the left and right direction. The swing arms of the two sets of the first wiping assembly are arranged vertically opposite each other, and the swing arms are provided with wiping parts for wiping the TP film.

[0008] As a preferred embodiment, the second support frame is provided with a front-to-back extending first electric slide rail, the two ends of the second mounting frame are connected to and driven by the first electric slide rail, and the two ends of the third mounting frame are connected to and driven by the first electric slide rail.

[0009] As a preferred embodiment, the alcohol cleaning device further includes a temperature sensor for sensing the temperature of the alcohol and a thermostat for controlling the temperature of the alcohol.

[0010] As a preferred embodiment, the petroleum ether cleaning device includes a petroleum ether tank into which the TP membrane is immersed and passes, and a second wiping assembly for wiping and cleaning the TP membrane in the petroleum ether tank.

[0011] As a preferred embodiment, the petroleum ether cleaning device also includes a ventilation mechanism and a cover for covering the petroleum ether tank.

[0012] As a preferred embodiment, a cold air drying device is provided between the alcohol cleaning device and the petroleum ether cleaning device, the cold air drying device being used to dry the alcohol on the TP membrane of the alcohol cleaning device.

[0013] As a preferred embodiment, the cold air drying device has a strip-shaped air outlet, the extension direction of which is consistent with the transport direction of the TP film, and the strip-shaped air outlet covers the upper and lower surfaces of the TP film.

[0014] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solution, its main features are: By setting up a water wetting device before the alcohol cleaning device, the TP membrane can be pre-wetted during actual cleaning (and the water does not easily evaporate, maintaining a good wetting effect). Then, it is immersed in alcohol for cleaning, and the alcohol can quickly dissolve the contaminants and remove them. Finally, a petroleum ether cleaning device is used for cleaning. The combination of alcohol and petroleum ether can target more types of contaminants and has a better cleaning effect.

[0018] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention.

[0019] It should be noted that when a component is said to be "fixed to" another component, it can be directly attached to the other component or there may be an intervening component. When a component is said to be "connected to" another component, it can be directly connected to the other component or there may be an intervening component. The terms "vertical," "horizontal," "left," "right," and similar expressions used in this document are for illustrative purposes only.

[0020] Please see Figures 1 to 7 This invention provides a TP membrane cleaning device, including an organic body 20, on which a discharge roll 21 is provided, and a transmission roller group 22, a water wetting device 30 for wetting the upper and lower surfaces of the TP membrane 10, an alcohol cleaning device 40 for cleaning the upper and lower surfaces of the TP membrane 10, a petroleum ether cleaning device 50 for cleaning the upper and lower surfaces of the TP membrane 10, and a receiving roll (not shown in the figure) for receiving the material.

[0021] By setting a water wetting device 30 before the alcohol cleaning device 40, the water wetting device 30 can pre-wet the TP membrane 10 during actual cleaning (and the water does not easily evaporate, so it can maintain the wetting effect well). Then, it is immersed in alcohol for cleaning. The alcohol can quickly dissolve the contaminants and clean them away. Finally, the petroleum ether cleaning device 50 is used for cleaning. The combination of alcohol and petroleum ether can target more cleaning objects and has a better cleaning effect.

[0022] Furthermore, the water wetting device 30 includes a first support frame 31, a first mounting frame 32, and two wetted cotton plates 33. The first support frame 31 is mounted on the body 20. The left and right ends of the first mounting frame 32 are respectively provided with vertically extending first tracks 34. Each first track 34 is slidably provided with two front-to-back extending support rods 35. Each wetted cotton plate 33 is provided with front-to-back extending mounting through holes 331 on both sides. The mounting through holes 331 on both sides of each wetted cotton plate 33 are respectively fitted onto the corresponding support rods 35 in the front-to-back direction. The left and right sides of the first mounting frame 32 are also respectively provided with opening and closing cylinders 36. The two driving parts of each opening and closing cylinder 36 are respectively connected to the two corresponding support rods 35, thereby driving the two support rods 35 to move relative to each other, and thus driving the wetted cotton plates 33 to open and close in the vertical direction. In actual operation, the TP membrane 10 passes through the gap between the two wet cotton plates 33. When the TP membrane 10 is wetted, the opening and closing cylinder 36 controls the two wet cotton plates 33 to contact the upper and lower surfaces of the TP membrane 10 respectively. In this way, the TP membrane 10 can be wetted. The wet cotton plates 33 are installed by a socket connection, which is convenient for subsequent maintenance and replacement. The installation method is also simple.

[0023] Furthermore, the alcohol cleaning device 40 includes an alcohol tank 41 through which the TP membrane 10 is immersed and passed, and a first wiping component 42 for wiping and cleaning the TP membrane 10 in the alcohol tank 41. In practice, if the amount of alcohol is too small (for example, by spraying alcohol onto the TP membrane 10), it is difficult to effectively dissolve dirt, especially for cleaning a large area of ​​membrane material. Spraying alcohol easily causes it to evaporate, and furthermore, alcohol does not adhere well to the lower surface of the TP membrane 10 because it tends to fall due to gravity. Therefore, we use the immersion method in the alcohol tank 41 to solve the above problems.

[0024] Furthermore, the alcohol cleaning device 40 also includes a second support frame 43, a second mounting frame 44, and a third mounting frame 45. The second mounting frame 44 extends left and right and is mounted on the second support frame 43. The left and right ends of the second mounting frame 44 are respectively provided with first clamping mechanisms 46 for clamping the left and right edges of the TP film 10. The third mounting frame 45 extends left and right and is mounted on the second support frame 43. The left and right ends of the third mounting frame 45 are respectively provided with second clamping mechanisms 47 for clamping the left and right edges of the TP film 10. The first wiping assembly 42 consists of two sets, which are arranged vertically opposite each other on the third mounting frame 45. Each set of the first wiping assembly 42 includes two swing arms 421 and a swing drive mechanism 422 for driving the two swing arms 421 to swing back and forth in the left and right direction. The swing arms 421 of the two sets of the first wiping assembly 42 are arranged vertically opposite each other, and the swing arms 421 are provided with wiping parts 423 for wiping the TP film 10. In practice, the first clamping mechanism 46 and the second clamping mechanism 47 are needed to clamp and support the TP film 10. Then, the swing drive mechanism 422 drives the swing arm 421 to move back and forth, thereby cleaning the upper and lower surfaces of the TP film 10. It should be noted that the TP film 10 moves along the transmission direction (front and back direction), while the swing arm 421 wipes along the left and right direction. In this way, the TP film 10 and the swing arm 421 can move relative to each other in two directions, which can achieve a better wiping effect. The wiping element 423 is a sponge or a lint-free cloth, which is selected according to the actual situation. Furthermore, the swing drive mechanism 422 is similar to the windshield wiper drive method of a car, so that the swing arm 421 moves along an arc. This is existing technology and will not be described in detail here.

[0025] Furthermore, the second support frame 43 is provided with a front-to-back extending first electric slide rail 48. Both ends of the second mounting bracket 44 are connected to and driven by the first electric slide rail 48. Both ends of the third mounting bracket 45 are also connected to and driven by the first electric slide rail 48. In practice, sometimes it is necessary to adjust the clamping position according to the thickness of the TP film 10 or the cleaning range of the swing arm 421, thus adapting to more needs.

[0026] Furthermore, the alcohol cleaning device 40 also includes a temperature sensor (not shown) for sensing the alcohol temperature and a thermostat (not shown) for controlling the alcohol temperature. Since alcohol is highly volatile, its temperature needs to be controlled to conserve alcohol and also to ensure temperature control during cleaning; a low temperature can prevent rapid evaporation. Furthermore, the bottom of the alcohol tank 41 is provided with a drain hole, through which dirt can be discharged when it reaches a certain level.

[0027] Furthermore, the petroleum ether cleaning device 50 includes a petroleum ether tank 51 through which the TP membrane 10 is immersed and passed, and a second wiping component 52 for wiping and cleaning the TP membrane 10 in the petroleum ether tank 51. Similarly, in practice, if the amount of petroleum ether is too small, it is difficult to effectively dissolve dirt, especially for large-area membrane cleaning. Spraying the membrane would cause the petroleum ether to evaporate easily. Furthermore, the lower surface of the TP membrane 10 is also difficult to adhere to because the petroleum ether tends to fall due to gravity. Therefore, we use the immersion method in the petroleum ether tank 51 to solve the above problems. Additionally, it should be noted that the structure of the second wiping component 42 is similar to that of the aforementioned first wiping component 42, and will not be described again here.

[0028] Furthermore, the petroleum ether cleaning device 50 also includes a ventilation mechanism (not shown) and a cover (not shown) for covering the petroleum ether tank 51. Since the human body cannot inhale large amounts of petroleum ether gas, otherwise it is easy to feel dizzy, and petroleum ether itself is also volatile, it is necessary to cover it with a cover and then use a ventilation device to collect the petroleum ether gas to prevent it from spreading into the air.

[0029] Furthermore, a cold air drying device 60 is provided between the alcohol cleaning device 40 and the petroleum ether cleaning device 50. The cold air drying device 60 is used to dry the alcohol on the TP membrane 10 of the alcohol cleaning device 40. In practice, drying the alcohol on the TP membrane 10 is necessary to prevent the alcohol from interfering with the dissolving effect of the petroleum ether.

[0030] Furthermore, the cold air drying device 60 has a strip-shaped air outlet 61, the extension direction of which is consistent with the transmission direction of the TP film 10, and the strip-shaped air outlet 61 covers the upper and lower surfaces of the TP film 10. By designing the strip-shaped air outlet 61, air can be blown onto the upper and lower surfaces of the TP film 10, without disturbing the airflow over a large area, thus preventing dust in the air from adhering to the upper and lower surfaces of the TP film 10.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the principles of the present invention should be included within the protection scope of the present invention.
