Description

Technical Field

[0002] With the rapid development of science and technology, liquid crystal displays (LCDs) have become one of the most common display technologies in electronic devices, and are widely used in a variety of products such as mobile phones, computers, and televisions. In the LCD manufacturing process, it is crucial to ensure good electrical contact between the various components, especially for the terminal areas that connect the driver integrated circuit (IC) or flexible printed circuit board (FPC). If these terminal areas are contaminated, poor contact may occur, which in turn affects the display effect and even causes product failure. Therefore, effective cleaning of LCD terminals has become an important part of the production process.

The front left side of the mounting plate 5 is rotatably connected to two limit wheels 24, and a retaining frame 25 is also connected to the left side of the mounting plate 5.

[0033] like Figure 1 and Figure 5 As shown, the opening and closing assembly includes a fixed rod 26, a fixed rack 27, a mounting block 28, a rotating gear 29 and a second electric push rod 30. The right side of the sliding block 8 located on the upper side is connected to the fixed rod 26, and the right side of each sliding block 8 is connected to a fixed rack 27.

The second electric push rod 30 is connected to the front side of the upper part of the connecting column 16, and the telescopic rod of the second electric push rod 30 can be extended to contact and cooperate with the fixed rod 26.

[0034] like Figure 6 and Figure 7As shown, the cleaning component includes a liquid storage tank 31, a liquid outlet pipe 32, a solenoid valve 33, a third electric push rod 34, a U-shaped block 35, a sponge block 36 and an infrared sensor 37. The top of the connecting column 16 is connected to the liquid storage tank 31, and a cover is provided on the front side of the top of the liquid storage tank 31. The cleaning agent can be added into the liquid storage tank 31 by opening the cover. The bottom front side of the liquid storage tank 31 is connected to the liquid outlet pipe 32, and the solenoid valve 33 is installed at the lower end of the liquid outlet pipe 32. The front side of the upper part of the connecting column 16 is connected to the third electric push rod 34, and the third electric push rod 34 is located on the left side of the second electric push rod 30. The U-shaped block 35 is connected to the telescopic rod of the third electric push rod 34. The U-shaped block 35 is hollow, and the lower end of the liquid outlet pipe 32 is connected to the top of the U-shaped block 35. The sponge blocks 36 are symmetrically connected to the inner side of the U-shaped block 35, and an infrared sensor 37 is installed on the upper front side of the U-shaped block 35.

[0035] Initially, a certain amount of cleaning agent is stored in the liquid storage tank 31, and part of the cleaning agent in the liquid storage tank 31 will flow into the liquid outlet pipe 32 due to gravity, and a certain amount of cleaning agent is also absorbed inside the sponge block 36; first, the device is installed in the designated position so that the robot can clamp a piece of LCD and move it left and right in front of the device, and then manually put multiple rolls of dust-free cloth on each placement shaft 6, and then pull one end of the dust-free cloth forward, and pass the end of the dust-free cloth around the corresponding rotating wheel 10, and then pass through between the two limiting wheels 24, and finally place the end of the dust-free cloth between the semicircular block 21 and the sliding clamping block 22, and then push the sliding clamping block 22 forward, so that the sliding clamping block 22 and the semicircular block 21 can cooperate to clamp the end of the dust-free cloth until two rolls of dust-free cloth are installed on the eight mounting plates 5; then the eight mounting plates 5 are slid and installed on the first tray 3 and the second tray 4, and then place the first tray 3 and the second tray 4 on the top of the bottom plate 1 in sequence, so that the front sides of the first tray 3 and the second tray 4 are in contact with the rear side of the limiting rod 14, and the limiting rod 14 plays a limiting role, so that the first tray 3 and the second tray 4 are aligned with the guide rail 2, and then the first tray 3 and the second tray 4 are pushed to the right, and the first tray 3 and the second tray 4 can drive the driven rack 13 to move to the right. When the driven rack 13 is engaged with the driving gear 12, since the driving motor 11 has no self-locking function (the driving gear 12 can rotate at will when the driving motor 11 is not working), the driven rack 13 can drive the driving gear 12 to rotate freely, thereby not affecting the movement of the driven rack 13, so that the first tray 3 and the second tray 4 can be slidably installed on the guide rail 2 until the rightmost fixing rod 26 is located directly below the second electric push rod 30;Then, the control box 101 controls the first electric push rod 17 to drive the servo motor 18 and the connecting gear 19 to move downward, so that the connecting gear 19 is meshed with the connecting gear ring 15 on the upper side. At the same time, the control box 101 controls the third electric push rod 34 to drive the U-shaped block 35 to move downward, so that the U-shaped block 35 moves to the left side of the two rightmost rotating wheels 10, and then the manipulator clamps a piece of LCD and moves it from left to right. When the infrared sensor 37 detects that a terminal of an LCD passes through the inner side of the U-shaped block 35, the sponge block 36 can wipe and clean the terminal of the LCD under the action of the detergent, and the infrared sensor 37 will send a signal. After receiving the signal, the control box 101 will control the solenoid valve 33 to work. At this time, the solenoid valve 33 will open for one second, so that the detergent in the liquid outlet pipe 32 will fall down into the U-shaped block 35 due to gravity to replenish the detergent in the sponge block 36, and the detergent in the liquid storage tank 31 will be replenished into the liquid outlet pipe 32 due to gravity. After one second, the control box 101 will control the solenoid valve 33 to close, and at the same time, the control box 101 will control the extension rod of the second electric push rod 30 to extend, so as to push the rightmost fixed rod 26 to move downward, so as to drive the upper sliding block 8 and the upper fixed rack 27 to move downward, and under the meshing action of the rotating gear 29, the lower fixed rack 27 and the lower sliding block 8 can be driven to move upward, and the connecting spring 9 is stretched, and the sliding block 8 can drive the rotation of the upper and lower sides. The wheels 10 move toward the side that is close to each other. At this time, the terminals of the LCD just move between the two rotating wheels 10. The part of the dust-free cloth on the rotating wheel 10 can wipe and clean the terminals of the LCD. Then the control box 101 will control the telescopic rod of the second electric push rod 30 to shorten, so that the telescopic rod of the second electric push rod 30 is separated from the fixed rod 26 on the far right. The connecting spring 9 will return to its original state, driving the sliding blocks 8, the rotating wheels 10 and the fixed rack 27 on the upper and lower sides to move away from each other and reset. Then the control box 101 will control the servo motor 18 to work for one second. The servo motor 18 can drive the connecting gear 19 to rotate, and the connecting gear 19 can drive the upper connecting gear ring 15 to rotate, thereby driving the lower connecting gear ring 15 rotates, the connecting gear ring 15 can drive the placement shaft 6 to rotate to release the dust-free cloth. At the same time, the placement shaft 6 on the upper side can drive the rotating disk 20 to rotate through the pulley assembly 23. The rotating disk 20 can reel in the dust-free cloth through the cooperation of the semicircular block 21 and the sliding clamp block 22. The limiting wheel 24 is used to guide the dust-free cloth. The retaining frame 25 is used to limit the dust-free cloth and prevent the dust on the use part of the dust-free cloth from falling down to the surface of the dust-free cloth on the lower placement shaft 6. In this way, the part of the dust-free cloth on the rotating wheel 10 can be replaced, which is convenient for wiping and cleaning the terminals of the next LCD. After one second, the control box 101 will control the servo motor 18 to stop working, so that the placement shaft 6 and the rotating disk 20 stop rotating;In this way, the terminals of the LCD can be automatically wiped and cleaned. As the use time increases, the dust-free cloth on the placement shaft 6 will gradually decrease, and the first distance sensor 1601 can monitor the thickness of the dust-free cloth on the upper placement shaft 6 in real time. When the dust-free cloth on the upper placement shaft 6 is used up, the first distance sensor 1601 will send a signal. After receiving the signal, the control box 101 will control the first electric push rod 17 to drive the servo motor 18 and the connecting gear 19 to move upward and reset, so that the connecting gear 19 is separated from the upper connecting gear ring 15. At the same time, the control box 101 will control the third electric push rod 34 to drive the U-shaped block 35 to move upward and reset, so as to prevent the U-shaped block 35 from affecting the movement of the mounting plate 5. Then the control box 101 will control the driving motor 11 to drive the driving gear 12 to rotate, and the driving gear 12 can drive the driven rack 13 to move a specified distance to the right, thereby driving the first tray 3 and the second tray 4 to move a specified distance to the right. 4 can drive the mounting plate 5 thereon to move to the right, so that the second fixing rod 26 from the right to the left is located directly below the second electric push rod 30. Repeating the above operation can enable the device to use the dust-free cloth on the second mounting plate 5 from the right to the left to wipe and clean the subsequent LCD terminals. The entire replacement work can be completed within the time interval between the robot taking two LCDs. When the four rolls of dust-free cloth on the second tray 4 are used up, the second tray 4 will move to the right and disengage from the guide rail 2, and the device can use the dust-free cloth on the first tray 3 to wipe and clean the subsequent LCD terminals. At this time, the mounting plate 5 on the second tray 4 can be manually slid off, and the dust-free cloth on the mounting plate 5 can be replaced, and then the mounting plate 5 can be slid back onto the second tray 4, and then the second tray 4 can be reinstalled on the guide rail 2. In this way, there is no need to shut down the entire device, and the cleaning work of the LCD terminals can be completed continuously, thereby improving the overall work efficiency. ;

[0036] like Figure 8-Figure 10As shown, it also includes a second distance sensor 38, a positioning block 39, a fixing block 40 and a magnet 41. The second distance sensor 38 is installed at the bottom of the servo motor 18, the positioning block 39 is connected to the right side of the connecting gear 19, the fixing block 40 is connected to the front side of the top of the mounting plate 5, and the magnet 41 is connected to the left side of the fixing block 40; when the dust-free cloth is manually installed on the placement shaft 6, the upper connecting gear ring 15 can be manually rotated so that a tooth on the upper connecting gear ring 15 can be parallel to the magnet 41, so that the angle of the upper connecting gear ring 15 can be adjusted, and at the same time, the magnet 41 can generate a certain suction force on the upper connecting gear ring 15 due to the magnetic force, thereby preventing the upper connecting gear ring 15 from rotating at will; whenever the control box 1 01 After controlling the first electric push rod 17 to drive the connecting gear 19 to move upward and separate from the connecting gear ring 15 on the upper side, the control box 101 will control the servo motor 18 to drive the connecting gear 19 to rotate. The connecting gear 19 can drive the positioning block 39 to rotate. When the positioning block 39 rotates to be horizontally aligned with the second distance sensor 38, the second distance sensor 38 can send a signal. After receiving the signal, the control box 101 will control the servo motor 18 to stop working. The servo motor 18 has a self-locking function (when the servo motor 18 is not working, the connecting gear 19 cannot rotate at will). In this way, the angle of the connecting gear 19 can be adjusted to ensure that the connecting gear 19 can move downward and perfectly mesh with the next connecting gear ring 15.

[0037] like Fig.11 and Fig.12 As shown, it also includes a connecting block 43 and a limiting spring piece 44. The lower part of the mounting plate 5 is symmetrically provided with a slot 42. The front and rear sides of the top of the first tray 3 and the second tray 4 are symmetrically connected with the connecting blocks 43. The side of the connecting block 43 close to the mounting plate 5 is connected with a limiting spring piece 44. The limiting spring piece 44 is stuck in the slot 42 to limit the mounting plate 5. When the mounting plate 5 is manually slid and installed on the first tray 3 and the second tray 4 respectively, the limiting spring piece 44 and the slot 42 can limit the mounting plate 5 on the left and right sides of the first tray 3 and the second tray 4, so as to prevent the mounting plate 5 from moving at will, and facilitate the subsequent replacement of the dust-free cloth.
