[0035] Exemplary embodiments will be described in detail herein, examples of which are shown in the accompanying drawings. When the following description refers to the drawings, the same numbers in different drawings represent the same or similar elements unless otherwise indicated. The implementations described in the following exemplary embodiments do not represent all implementations consistent with the present application. Instead, they are merely examples of devices and methods consistent with some aspects of the present application as detailed in the appended claims.

[0036] See also Figure 1 and Figure 3 The protective film renewal method provided in the embodiment of the present application can be applied to Figure 1 In the self-service terminal shown, Figure 1 and Figure 3 The figure shows a front view of the screen of the self-service terminal of an embodiment of the present application, wherein the self-service terminal includes a self-service terminal body 1 and a touch screen 2, the touch screen 2 is arranged on the self-service terminal body 1, and the surface of the touch screen 2 is covered with a protective film 4, so that the customer can operate on the touch screen 2 through the protective film 4.

[0037] Furthermore, the self-service terminal further comprises an outlet device 3, a recycling device 5 and a detection device 6. The outlet device 3 and the recycling device 5 are symmetrically arranged on opposite sides of the self-service terminal, and the detection device 6 is arranged in the recycling device 5. Exemplarily, Figure 1 The outlet device 3 and the recovery device 5 are arranged on the left and right sides of the touch screen 2, and can also be arranged on the upper and lower sides of the touch screen 2 in actual application.

[0038] See also Figure 2 , Figure 2 Optionally, the outlet device 3 includes a protective film outlet 31 , a protective film placement box 32 and a first rotating device 33 , and the protective film 4 includes a new protective film 41 and an old protective film 42 .

[0039] The protective film placement box 32 is arranged in the self-service terminal body 1, and the new protective film 41 is placed in the protective film placement box 32. With this solution, after the customer completes the operation on the LCD screen 2, the first rotating device 33 rotates in a first preset direction, so that the new protective film 41 is passed from the protective film placement box 32 through the protective film outlet 31 to cover the surface of the LCD screen 2, waiting for the next customer to use it, and the old protective film 42 is recycled to the recycling device 5.

[0040] Furthermore, the self-service terminal further includes a power device 8 and a controller 9, which are arranged inside the self-service terminal body 1. When the controller 9 receives the user operation completion instruction, it outputs a control signal to the power device 8, so that the power device 8 provides power to the first rotating device 33, drives the first rotating device 33 to rotate in a first preset direction, covers the new protective film 41 to the surface of the liquid crystal screen 2, and recycles the old protective film 42 to the recycling device 5. Exemplarily, the transmission method of the power device 8 can adopt various transmission methods such as belts and gears.

[0041] Furthermore, the detection device 6 detects the cleanliness of the old protective film 42 in the recycling device 5 to confirm whether the cleanliness of the old protective film 42 meets the preset requirements. If the cleanliness meets the preset requirements, it indicates that the scratches, fingerprints and other damages on the surface of the old protective film 42 are relatively minor and can continue to be used, then the first rotating device 33 is driven to rotate in the opposite direction of the first preset direction to re-cover the old protective film 42 on the surface of the touch screen 2. It should be understood that at this time, the new protective film 41 is rotated back into the protective film placement box 32.

[0042] Exemplarily, the detection device 6 detects the cleanliness of the old protective film 42 in the recovery device 5 based on the optical detection principle.

[0043] See also Figure 3 Optionally, the detection device 6 includes an optical signal emitting unit 61 and an optical signal receiving unit 62. The optical signal emitting unit 61 is used to emit an optical signal after startup, and the optical signal vertically passes through the old protective film 42 and is transmitted to the optical signal receiving unit 62 for reception. The controller 9 detects the intensity of the optical signal received by the optical signal receiving unit 62, and determines whether the cleanliness meets the preset requirements based on the intensity of the optical signal. The optical signal emitting unit 61 and the optical signal receiving unit 62 are located on both sides of the bottom of the recycling device 5. It should be noted that in order to ensure the sensitivity of the optical signal detection, the recycling device 5 of the embodiment of the present application is made of opaque material.

[0044] Exemplarily, the controller 9 determines whether the cleanliness meets the preset requirements based on the intensity of the light signal, including: constructing a light wave dot matrix according to the size of the old protective film 42, wherein the light wave dot matrix includes a plurality of light spots. It should be understood that in this embodiment, the area involved in the light wave dot matrix is ​​determined in advance based on the customer's operating area on the protective film 4. Generally speaking, the area is a rectangular structure and includes a plurality of evenly distributed light spots S1, S2, ... Sn, where n is the number of light spots; the light intensity of each light spot is defined as Si. If the protective film 4 is brand new and uncontaminated, the light intensity of each light spot is defined as the full score Smax.

[0045] Further, the controller 9 calculates the pass rate α of the light wave array according to the light signal intensity Si of each light spot, and the expression is: α=sum(Si1:Sin) / Smax×n; wherein Si1 represents the light intensity of the first light spot, and Sin represents the light intensity of the nth light spot. If the pass rate α is greater than the preset cleanliness target rate β, it is considered that the cleanliness of the old protective film 42 meets the preset requirements.

[0046] Optionally, the cleanliness target rate β can be set or modified in real time as needed, and a default value can also be adopted, such as the default setting of the cleanliness target rate β=90%.

[0047] Optionally, the receiving frequency of the optical signal receiving unit 62 can also be set. Exemplarily, the optical signal receiving unit 62 periodically receives the optical signal emitted by the optical signal emitting unit 61 at a preset frequency, for example, t=0.1 second. This can control the total number of light spots finally collected, thereby saving the computing performance of the controller 9.

[0048] For example, the first rotating device 33 in this embodiment adopts a quinone rotating shaft, which is a rotatable cylindrical quinone with both ends fixed in the protective film placement box 32. When installing, the protective film placement box 32 is opened and the rolled protective film 4 is installed on the quinone rotating shaft. After receiving the control signal of the controller, the power device 8 provides electrical energy to the first rotating device to rotate it. In this embodiment, the first preset direction is clockwise.

[0049] Optionally, the outlet device 3 further includes a third rotating device 34, which is disposed in the protective film outlet 31. For example, the third rotating device 34 uses a rotatable cylindrical gel quinone as a rotatable shaft for the protective film 4 to slide, and does not provide power itself. At this time, the new protective film 41 rotates from the gel quinone shaft, and rotates from the protective film outlet 31 to the surface of the liquid crystal screen 2 via the third rotating device 34. At the same time, the old protective film 42 is also driven to move into the recycling device 5 under the rotation of the first rotating device 33.

[0050] Optionally, the recovery device 5 includes a protective film recovery port 51 and a fourth rotating device 52. Exemplarily, the fourth rotating device 52 and the third rotating device 34 adopt the same rotatable cylindrical gel quinone structure, which only serves as a rotatable shaft for the protective film to slide, and does not provide power itself. Exemplarily, the width of the protective film outlet 31 and the protective film recovery port 51 is slightly longer than the touch screen 2, and the position is slightly higher than the touch screen 2, so that the protective film 4 can completely cover the touch screen 2.

[0051] It should be noted that, in another embodiment, the third rotating device 34 and the fourth rotating device 52 can also be powered by the power device 8 to actively rotate, so that the protective film 4 can be better slid, transported and replaced.

[0052] Optionally, the self-service terminal further includes a destruction device 7, which is disposed in the recycling device 5, and includes a destruction recycling box 71 and a second rotating device 72, and the second rotating device 72 is disposed in the destruction recycling box 71. If the cleanliness of the old protective film 42 does not meet the preset requirements, the controller 9 drives the second rotating device 72 to rotate in a second preset direction after receiving the customer's operation completion instruction next time, so as to move the old protective film 42 to the destruction recycling box 71 for destruction.

[0053] See also Figure 4 Optionally, the second rotating device 72 includes a left crushing knife 721 and a right crushing knife 722. The destruction device 7 also includes a cache shaft 73. The left crushing knife 721 and the right crushing knife 722 are rotatable cylindrical crushing knives whose two ends are fixed in the destruction recovery box 71, and the cache shaft 73 is arranged between the left crushing knife 721 and the right crushing knife 722. After the old protective film 42 is recovered to the recovery device 5, it will be wound onto the cache shaft 73 through the rotation of the cache shaft 73. If there is an old protective film 42 that failed the last inspection on the cache shaft 73, the unqualified old protective film 42 will be crushed and destroyed by the left crushing knife 721 and the right crushing knife 722 as the cache shaft 43 rotates this time. The destruction recovery box 71 can be opened to take out the crushed and recycled waste protective film.

[0054] The power device 8 is a second rotating device 72 that acts on the crushing blade gear 7211 to rotate the left crushing blade 721 and the right crushing blade 722 in a second preset direction. The second preset direction includes two opposite directions, that is, the movement directions of the left crushing blade 721 and the right crushing blade 722 are opposite. For example, when the power device 8 is powered, the left crushing blade 721 rotates clockwise and the right crushing blade 722 rotates counterclockwise.

[0055] There are many ways to make a crushing knife. According to the different ways of making the crushing knife, the existing crushing modes include: crushed, granular, segmented, foamy, strip-shaped, filamentous, etc.

[0056] See also Figure 5 , Figure 5The diagram shows a schematic diagram of a pulverizer that can be cut into segments provided by an embodiment of the present application. The left pulverizer 721 is composed of a long axis 7213 and a short axis 7214 that are spaced in sequence; there are pulverizer gears 7211 at both ends of the left pulverizer 721, which are used to be fixed in the destruction and recovery box 71 and provide transmission power; the left pulverizer 721, the long axis 7213, the short axis 7214, and the pulverizer gear 7211 are fixed as a whole and rotate synchronously; sharp teeth 7212 are distributed on the long axis 7213. The right pulverizer 722 is also composed of a long axis 7213 and a short axis 7214 that are spaced in sequence, and there are pulverizer gears 7211 at both ends of the right pulverizer 722; the right pulverizer 722, the long axis 7213, the short axis 7214, and the pulverizer gear 7211 are fixed as a whole and rotate synchronously. The long axis 7213 of the left crushing knife 721 corresponds to the short axis 7214 of the right crushing knife 722; the short axis 7214 of the left crushing knife 721 corresponds to the long axis 7213 of the right crushing knife 722; the long axes and short axes of the two left crushing knives correspond to each other and are in close contact, and the purpose of cutting and crushing the protective film can be achieved when rotating.

[0057] The following combination Figure 1-Figure 5 , the working principle of automatic replacement of protective film by self-service terminal is explained:

[0058] After receiving the instruction of the customer's operation completion, the controller 9 outputs a control signal to the first rotating device 33 to drive the first rotating device 33 to rotate clockwise, so that the new protective film 41 is covered on the surface of the LCD screen 2 from the protective film placement box 32 through the protective film outlet 31 for the customer to use; at the same time, the old protective film 42 is recovered to the recovery device 5 for the detection device 6 to detect its cleanliness. If the cleanliness meets the preset requirements, the controller 9 drives the first rotating device 33 to rotate counterclockwise to re-cover the old protective film 42 on the surface of the LCD screen 2, and the new protective film 41 is rotated back into the protective film placement box 32. If the cleanliness does not meet the preset requirements, the process ends, and the new protective film 41 continues to cover the surface of the LCD screen 2 for the next customer to use; after receiving the instruction of the customer's operation completion next time, the controller 9 outputs a control signal to the second rotating device 72 to drive the left crushing knife 721 to rotate clockwise and the right crushing knife 722 to rotate counterclockwise to crush and destroy the unqualified old protective film 42 covering the cache shaft 73.

[0059] After receiving the customer's operation completion instruction, the above self-service terminal covers the new protective film on the surface of the LCD screen, recycles the old protective film, and detects the cleanliness of the recycled old protective film. If the cleanliness meets the requirements, the old protective film is re-covered on the surface of the LCD screen. This application can automatically detect the cleanliness of the protective film after the previous customer has finished using it. If it is found that the protective film cannot be used anymore, the protective film on the touch screen will be automatically replaced and the old film will be destroyed. It can protect the screen, reduce scratches on the touch screen, and extend the service life of the touch screen; it can also collect and destroy the customer's fingerprints in time to prevent customer information from being stolen by criminals; it can also improve health and safety standards and eliminate health hazards.

[0060] See also Figure 6 In one embodiment, the present application provides a protective film updating method, which is described by applying the method to the above self-service terminal. The protective film updating method includes:

[0061] Step 602: In response to the customer operation completion instruction, the first rotating device is driven to rotate in a first preset direction to update the new protective film to the surface of the touch screen, and the old protective film is recycled to the recycling device.

[0062] Step 604: Check whether the cleanliness of the old protective film meets the preset requirements.

[0063] Step 606: If the cleanliness of the old protective film meets the preset requirement, the first rotating device is driven to rotate in the opposite direction of the first preset direction to re-cover the old protective film on the surface of the touch screen.

[0064] Specifically, the customer operation completion instruction is generated when the customer completes the business on the LCD screen and exits the operation through the self-service terminal's own function. After receiving the customer operation completion instruction, the controller of the self-service terminal controls each device of the self-service terminal and enters the working mode.

[0065] The new protective film is a protective film that has not been used by a customer, and the old protective film is a protective film that has been used by the previous customer. It should be understood that the new protective film and the old protective film have the same size, and the size matches the area of ​​the LCD screen, so that the protective film can completely cover the surface of the LCD screen. In order to achieve the matching of the size of the protective film and the area of ​​the LCD screen, the width of the protective film can be set to be slightly larger than the width of the LCD screen; at the same time, each time the LCD screen is updated, the controller drives the first rotating device to move a preset distance, which is slightly larger than the length of the LCD screen. Exemplarily, the first preset direction of this embodiment is clockwise.

[0066] Detect the cleanliness of the old protective film, that is, detect whether there are scratches, fingerprints, dust and other phenomena on the surface of the old protective film. If the cleanliness meets the preset requirements, it is considered that the scratches, fingerprints or dust on the surface of the old protective film are relatively light and can continue to be used. The controller drives the first rotating device to rotate counterclockwise to re-cover the old protective film on the surface of the LCD screen for the next customer to use. After the next customer finishes using it, repeat the above steps again and detect the cleanliness of the protective film again. In this way, after each customer finishes using it, the controller will detect the cleanliness of the protective film currently covering the surface of the LCD screen to determine whether the protective film can continue to be used. While ensuring that the customer's use environment is clean and hygienic, it also saves the cost of use.

[0067] The above-mentioned protective film updating method detects the cleanliness of the protective film on the surface of the LCD screen. If the cleanliness meets the requirements, it will continue to be used. Otherwise, the protective film will be automatically replaced to ensure that the customer's usage environment is in a clean and hygienic state, prevent criminals from stealing customer information on the protective film, and save usage costs.

[0068] Optionally, the protective film updating method of the embodiment of the present application further includes:

[0069] If the cleanliness of the old protective film does not meet the preset requirements, the second rotating device is driven to rotate in a second preset direction after receiving the customer's operation completion instruction next time to move the old protective film to the destruction device for destruction.

[0070] Specifically, if the cleanliness does not meet the preset requirements, it indicates that the scratches, fingerprints or dust on the protective film currently used on the LCD screen are severe and cannot be used any longer. Since the new protective film has already covered the surface of the LCD screen at this time, the controller controls each device to stop working and the process ends. When the new customer completes the operation on the LCD screen, the controller receives the new customer's operation completion instruction and drives the second rotating device to move the old protective film to the destruction device for destruction. It should be understood that at this time, the controller also drives the first rotating device to cover the new protective film to the surface of the LCD screen. Exemplarily, the second preset direction includes two opposite directions, and the controller drives the second rotating device, that is, the controller drives the left crushing knife to rotate clockwise and the right crushing knife to rotate counterclockwise to destroy the old protective film.

[0071] The above-mentioned protective film updating method adopts a destruction device to destroy the protective film whose cleanliness does not meet the preset requirements, completely eliminating the risk of criminals stealing the customer's fingerprints on the protective film, and ensuring the security of customer information.

[0072] Optionally, check whether the cleanliness of the old protective film meets the preset requirements, including:

[0073] The detection device is based on the optical detection principle to detect whether the cleanliness of the old protective film meets the preset requirements.

[0074] Specifically, the principle of optical detection is that when light hits the surface of an object, reflection, transmission or scattering will occur. These phenomena are closely related to the state of the surface of the object, including the flatness, smoothness, cleanliness and whether there are defects on the surface. By detecting the changes in these light signals, the state information of the surface of the object can be indirectly obtained. In this embodiment, the optical detection principle is used to detect the cleanliness of the surface of the protective film.

[0075] The above-mentioned protective film updating method detects the cleanliness of the protective film surface based on the optical detection principle, which can quickly obtain the cleanliness of the protective film and save replacement time.

[0076] Optionally, based on the optical detection principle, the cleanliness of the old protective film is detected to see whether it meets the preset requirements, including:

[0077] The optical signal transmitting unit is activated so that the optical signal passes through the old protective film and is transmitted to the optical signal receiving unit.

[0078] The intensity of the optical signal received by the optical signal receiving unit is detected.

[0079] According to the intensity of the light signal, determine whether the cleanliness meets the preset requirements.

[0080] Specifically, the optical signal transmitting unit is used to convert the electrical signal into an optical signal and transmit it; the optical signal receiving unit is used to receive the optical signal and convert it into an electrical signal. In this embodiment, the optical signal emitted by the optical signal transmitting unit vertically passes through the old protective film in the recycling device and is transmitted to the optical signal receiving unit.

[0081] Optionally, determining whether the cleanliness meets preset requirements based on the intensity of the optical signal includes:

[0082] A light wave dot matrix is ​​constructed according to the size of the old protective film, wherein the light wave dot matrix includes a plurality of light spots.

[0083] According to the light signal intensity of each light spot, the passing rate of the light wave array is calculated.

[0084] If the pass rate is greater than the preset cleanliness target rate, it is considered that the cleanliness of the old protective film meets the preset requirements.

[0085] Specifically, before testing the cleanliness of the protective film surface, it is necessary to determine the testing area in advance based on the customer's operating area of ​​the protective film. The size of the old protective film here refers to the customer's operating area, and the constructed light wave dot matrix should cover the entire operating area. Exemplarily, the optical signal transmitting unit can use scanning technology or diffusion technology to cover the entire operating area with the emitted light signal.

[0086] For example, the detection area is a rectangular structure, and includes a plurality of evenly distributed light spots S1, S2, ... Sn, where n is the number of light spots; the light intensity of each light spot is defined as Si. If the protective film is brand new and uncontaminated, the light intensity of each light spot is defined as the full score Smax.

[0087] Furthermore, the controller calculates the pass rate α of the light wave array according to the light signal intensity Si of each light spot, and the expression is: α=sum(Si1:Sin) / Smax×n; wherein Si1 represents the light intensity of the first light spot, and Sin represents the light intensity of the nth light spot. If the pass rate α is greater than the preset cleanliness target rate β, it is considered that the cleanliness of the old protective film 42 meets the preset requirements.

[0088] Optionally, the cleanliness target rate β can be set or modified in real time as needed, and a default value can also be adopted, such as the default setting of the cleanliness target rate β=90%.

[0089] The above-mentioned protective film updating method divides the detection area into multiple evenly distributed light spots, calculates the pass rate of the light wave dot array according to the light signal intensity of each light spot, and then determines whether the cleanliness meets the preset requirements based on the pass rate. The protective film can be comprehensively and carefully inspected, and subtle scratches or fingerprints can be captured, effectively improving the detection accuracy.

[0090] Optionally, the protective film updating method of the embodiment of the present application further includes:

[0091] The optical signal receiving unit periodically receives the optical signal transmitted by the optical signal transmitting unit according to a preset frequency.

[0092] Specifically, by controlling the frequency received by the optical signal receiving unit, the total number of light spots finally collected can be controlled, thereby saving the computing performance of the controller.

[0093] The protective film updating method provided in the embodiment of the present application, after receiving the customer's operation completion instruction, covers the new protective film on the surface of the LCD screen, and recovers the old protective film at the same time, and detects the cleanliness of the recovered old protective film. If the cleanliness meets the requirements, the old protective film is re-covered on the surface of the LCD screen. This application can automatically detect the cleanliness of the protective film after the previous customer has finished using it. If it is found that this protective film cannot be used anymore, the protective film on the touch screen is automatically replaced and the old film is destroyed. It can not only protect the screen, reduce scratches on the touch screen, and extend the service life of the touch screen; it can also promptly recover the customer's fingerprints and destroy them to prevent customer information from being stolen by criminals; it can also improve health and safety standards and eliminate health hazards.
