Description

Technical Field

[0001] The present invention relates to the technical field of touch screen functional sheets, and in particular to an anti-interference touch screen functional sheet. Background Art

[0002] A touch screen functional sheet is an electronic component used in a touch screen. It is usually made of a layer of glass coated with an ITO film. This film can sense changes in capacitance and is used to achieve touch operations. The functional sheet is the core part of the touch screen. It is used in conjunction with a traditional printed circuit board to form the entire touch screen. After the functional sheet is made into small pieces of glass through processes such as silk screen printing and cutting, it eventually forms a complete touch screen. Touch screen functional sheets are widely used in various electronic devices, including public information query, multimedia information systems, medical equipment, industrial automatic control, etc.

[0003] The main differences between capacitive touch screens and resistive touch screens include that resistive touch screens work through pressure sensing, while capacitive touch screens utilize capacitive touch technology and work through the micro-electric signals of the human body.

[0017] Third: the card slot on the push plate is pressed against the baffle rod, driving the moving plate and the curved plate to rotate, so that the moving plate pulls the cleaning spring, and the dirt inside the cleaning plate falls into the collection box and leaves the inside of the equipment from the curved opening at the bottom of the collection box. When the card slot is separated from the baffle rod, the cleaning spring drives the moving plate and the curved plate to reclose the curved opening, which automatically handles the dirt and keeps the inside of the equipment clean.

[0030] A certain gap is designed between the lower electrode plate 29 and the upper electrode plate 30, the first scan line and the second scan line are positioned perpendicularly, the lower electrode 39 and the upper electrode 40 are electrically connected to the first scan line and the second scan line respectively, the first scan line and the second scan line are electrically connected to the second interface 41 respectively, the third scan line and the fourth scan line are positioned perpendicularly, the upper capacitor 42 and the lower capacitor 43 are electrically connected to the third scan line and the fourth scan line respectively, and the third scan line and the fourth scan line are electrically connected to the first interface 21 respectively.

[0031] In this embodiment, the housing 1 is mounted on the control screen of the automated machine tool, the mounting frame 9 is fixedly connected to the control screen of the automated machine tool, the first interface 21 is connected to the touch screen cable on the control screen of the automated machine tool, and when repairing the machine tool or modifying the automated machine tool program on site, a large amount of information needs to be quickly input on the screen, and precise signal input and multi-point touch are required. The second transparent plate 5 is operated by fingers. The second transparent plate 5, the upper capacitor plate 44, the partition 45, the lower capacitor plate 46 and the first bottom plate 7 are all transparent materials, and the partition 45 is also an insulating material. Since the charges of the upper capacitor 42 and the lower capacitor 43 are different, a stable electric field is formed between the upper capacitor 42 and the lower capacitor 43. When the finger touches the second transparent plate 5, the electric field changes. The signal position is scanned by the third scanning line and the fourth scanning line, and the signal is converted into a digital signal and transmitted to the computer for related operations.

[0032] Furthermore, the lower electrode plate 29, the upper electrode plate 30 and the second bottom plate 38 are stopped just above the second transparent plate 5. Since there is a certain gap between the lower electrode plate 29 and the upper electrode plate 30, the first transparent plate 2, the lower electrode plate 29, the upper electrode plate 30 and the second bottom plate 38 are all made of transparent materials, a finger touching the first transparent plate 2 will squeeze the upper electrode plate 30, causing the upper electrode plate 30 to be partially deformed, and the upper electrode 40 at this position contacts the lower electrode 39 on the lower electrode plate 29 to form a current, and the first scanning line and the second scanning line determine the scanning position, converting the signal into The digital signal is transmitted to the computer for related operations. The first transparent plate 2, the lower electrode plate 29, the upper electrode plate 30 and the second bottom plate 38 form a resistive touch screen. Since the operation of the first transparent plate 2, the lower electrode plate 29, the upper electrode plate 30 and the second bottom plate 38 requires a certain amount of pressure, when the CNC machine tool is processing parts in a normal environment, oil and water droplets fall on the first transparent plate 2, and no input signal can be generated, which improves the anti-interference performance of the touch screen under harsh conditions, and does not affect the precise signal input and multi-touch operations of the device.

[0033] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the shifting mechanism includes a rack 22 fixedly connected to one side edge of the moving frame 12, a fixed block 13 is fixedly connected to the bottom of the inner wall of the outer shell 1, a motor 23 is fixedly connected to the top of the fixed block 13, a worm gear 33 is fixedly connected to one end of the output shaft of the motor 23, a mounting rod 24 is fixedly connected to one side of the fixed block 13, and a gear 32 is rotatably connected to one end of the mounting rod 24.

[0034] The worm 33 meshes with the gear 32 , and the rack 22 meshes with the gear 32 . The worm 33 does not contact the rack 22 . The gear 32 can only rotate at one end of the mounting rod 24 , and the position of the gear 32 will not move at the position of the mounting rod 24 .

[0035] In this embodiment, by starting the motor 23 to drive the worm 33 and the gear 32, the rack 22 and the moving frame 12 are driven to move, so that the lower electrode plate 29, the upper electrode plate 30 and the second bottom plate 38 stay directly above the second transparent plate 5, thereby changing the position of the first transparent plate 2, the lower electrode plate 29, the upper electrode plate 30 and the second bottom plate 38.

[0036] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 In a preferred embodiment, the cleaning mechanism includes a push plate 25 fixedly connected to one side of the moving frame 12, a connecting rod 26 fixedly connected to the top of the push plate 25, one end of the connecting rod 26 is rotatably connected to a rotating plate 4, the bottom end of the rotating plate 4 is rotatably connected to a cleaning roller 28, a cleaning plate 27 is fixedly connected to the bottom end of the rotating plate 4 near the cleaning roller 28, and a flip spring 31 is fixedly connected to a position on the outer wall of one side of the moving frame 12 near the push plate 25.

[0037] A card slot is provided at one end of the push plate 25, a linkage slot is provided at the top of the rotating plate 4, a baffle is provided on the inner wall of one side of the rotating plate 4, and the position of the baffle is on the same horizontal line as the linkage slot on the rotating plate 4. The other end of the flip spring 31 is fixedly connected to the bottom of the rotating plate 4.

[0038] In this embodiment, during the forward movement of the moving frame 12, the linkage groove at the top of the rotating plate 4 squeezes the baffle bar, and the rotating plate 4 rotates to make the cleaning roller 28 and the cleaning plate 27 close to the surface of the second transparent plate 5. Through the relative movement of the moving frame 12 and the second transparent plate 5, the cleaning roller 28 continuously cleans the surface of the second transparent plate 5, and the cleaning plate 27 removes the dirt, thereby cleaning the surface of the second transparent plate 5 and preventing the dirt on the second transparent plate 5 from affecting the display effect.

[0039] Reference Figure 1 , Figure 2 , Figure 3 and Figure 6In a preferred embodiment, the sealing mechanism includes a fixed plate 11 fixedly connected to the bottom of the inner wall of the shell 1, a rotating rod is rotatably connected to one side of the fixed plate 11, a sealing roll 10 is arranged at one end of the rotating rod, a torsion spring 37 is arranged at one end of the rotating rod outside one end of the sealing roll 10, a knob 34 is rotatably connected to the other side of the fixed plate 11, a setting plate 35 is fixedly connected to the upper position of the knob 34 on the outer wall of one side of the shell 1, and a threaded rod 36 is threadedly connected to the upper surface of the setting plate 35.

The shape of the connecting frame is an inverted U shape, one end of the rotating rod is fixedly connected to the knob 34, and one end of the torsion spring 37 is fixedly connected to the connecting frame.

[0041] In this embodiment, during the movement of the first transparent plate 2, the lower electrode plate 29, the upper electrode plate 30 and the second bottom plate 38, the gap at this position may contaminate the equipment under harsh conditions. The sealing roll 10 is driven to move by the moving frame 12, and the sealing roll 10 will cover the gap left by the moving frame 12, so that the interior of the equipment is protected. The sealing roll 10 moves forward, which will cause the torsion spring 37 to twist. When the moving frame 12 returns to its original position, the torsion spring 37 drives the sealing roll 10 to retract, thereby retracting the sealing roll 10. After long-term use, the torsion spring 37 becomes loose, and the torsion spring 37 is twisted by rotating the mounting rod 24. The position of the knob 34 is fixed by twisting the threaded rod 36, so that the torsion spring 37 is always in an elastic state.

[0042] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the collecting mechanism includes a collecting box 15 fixedly connected to the inner wall of the other end of the outer shell 1, a connecting plate 18 is fixedly connected to the inner wall of the collecting box 15, a moving plate 19 is rotatably connected to one side of the connecting plate 18, a blocking rod 20 is designed on the top side of the moving plate 19, a fixing rod is designed on the top side of the moving plate 19 at the bottom of the blocking rod 20, a cleaning spring 17 is fixedly connected to one end of the fixing rod, and a cleaning port 8 is provided at the bottom of the outer shell 1 near the collecting box 15.

[0043] The other end of the cleaning spring 17 is fixedly connected to the connecting plate 18, and a curved plate is fixedly connected to one side of the moving plate 19. The bottom of the collecting box 15 is provided with an curved opening, and the curved plate just blocks the curved opening. The blocking rod 20 is used in conjunction with the card slot.

[0044] In this embodiment, the blocking rod 20 is pressed against the card slot on the push plate 25, driving the moving plate 19 and the curved plate to rotate, so that the moving plate 19 pulls the cleaning spring 17, and the dirt inside the cleaning plate 27 falls into the collecting box 15, and leaves the interior of the equipment from the curved opening at the bottom of the collecting box 15. When the card slot is separated from the blocking rod 20, the cleaning spring 17 drives the moving plate 19 and the curved plate to reclose the curved opening, thereby achieving the effect of automatically processing dirt and keeping the interior of the equipment clean.

[0045] Working principle: When in use, the shell 1 is installed on the control screen of the automatic machine tool, the installation frame 9 is fixedly connected to the control screen of the automatic machine tool, and the first interface 21 is connected to the touch screen cable on the control screen of the automatic machine tool. When repairing the machine tool or modifying the program of the automatic machine tool on site, it is necessary to quickly input a large amount of information on the screen, which requires precise signal input and multi-touch. The second transparent plate 5 is operated by fingers. The second transparent plate 5, the upper capacitor plate 44, the partition 45, the lower capacitor plate 46 and the first bottom plate 7 are all transparent materials, and the partition 45 is still an insulating material. Due to the different charges of the upper capacitor 42 and the lower capacitor 43, a stable electric field is formed between the upper capacitor 42 and the lower capacitor 43. When the finger touches the second transparent plate 5, the electric field changes, and the third scan The scanning line and the fourth scanning line scan signal position, convert the signal into a digital signal and transmit it to the computer for related operations. The second transparent plate 5, the upper capacitor plate 44, the partition 45, the lower capacitor plate 46 and the first bottom plate 7 form a capacitive touch screen structure, which has the advantages of accurate signal input and multi-point touch, but cannot distinguish impurities such as oil and water droplets, and has weak anti-interference performance. The worm rod 33 and the gear 32 are driven by the starting motor 23 to drive the rack 22 and the moving frame 12 to move, so that the lower electrode plate 29, the upper electrode plate 30 and the second bottom plate 38 stay directly above the second transparent plate 5. Since there is a certain gap between the lower electrode plate 29 and the upper electrode plate 30, the first transparent plate 2, the lower electrode plate 29, the upper electrode plate 30 and the second bottom plate 38 are all transparent materials. When a finger touches the first transparent plate 2, the upper electrode plate 30 is squeezed, causing the upper electrode plate 30 to be partially deformed. The upper electrode 40 at this position contacts the lower electrode 39 on the lower electrode plate 29 to form a current. The first scanning line and the second scanning line determine the scanning position, and the signal is converted into a digital signal and transmitted to the computer to perform related operations. The first transparent plate 2, the lower electrode plate 29, the upper electrode plate 30 and the second bottom plate 38 form a resistive touch screen. Since the operation of the first transparent plate 2, the lower electrode plate 29, the upper electrode plate 30 and the second bottom plate 38 requires a certain amount of pressure, when the CNC machine tool is processing parts in a normal environment, oil and water droplets fall on the first transparent plate 2, and no input signal can be generated, which has the effect of improving the anti-interference performance of the touch screen under harsh conditions. It will not affect the precise signal input and multi-touch operations of the device. During the movement of the first transparent plate 2, the lower electrode plate 29, the upper electrode plate 30 and the second bottom plate 38, the gap at this position will contaminate the device under harsh conditions. The sealing roll 10 is driven to move by the moving frame 12, and the sealing roll 10 will cover the gap left by the moving frame 12 to protect the inside of the device. The forward movement of the sealing roll 10 will cause the torsion spring 37 to twist. When the moving frame 12 returns to its original position, the torsion spring 37 drives the sealing roll 10 to retract, thereby retracting the sealing roll 10. After long-term use, the torsion spring 37 becomes loose, and the torsion spring 37 is driven to twist by rotating the mounting rod 24. The position of the knob 34 is fixed by twisting the threaded rod 36, so that the torsion spring 37 is always in an elastic state.During the forward movement of the moving frame 12, the linkage groove on the top of the rotating plate 4 squeezes the baffle bar, and the rotating plate 4 rotates to make the cleaning roller 28 and the cleaning plate 27 close to the surface of the second transparent plate 5. Through the relative movement of the moving frame 12 and the second transparent plate 5, the cleaning roller 28 continuously cleans the surface of the second transparent plate 5, and the cleaning plate 27 removes the dirt, which plays the effect of cleaning the surface of the second transparent plate 5 and preventing the dirt on the second transparent plate 5 from affecting the display effect. The card slot on the push plate 25 is against the baffle rod 20, driving the moving plate 19 and the arc plate to rotate, so that the moving plate 19 pulls the cleaning spring 17, and the dirt inside the cleaning plate 27 falls into the collection box 15 and leaves the interior of the device from the arc opening at the bottom of the collection box 15.
