Technical Field
[0001] The present invention relates to the technical field of display screen production, and in particular to a pre-folding process and pre-folding equipment based on lamination. Background Art
[0002] For foldable screen displays, such as flexible OLED displays, pre-folding is usually required after lamination. This is because foldable screen displays need to be bent or folded at specific locations to ensure that they maintain good display effects and durability in both unfolded and folded states. Pre-folding can help the display be smoother when bent or folded, reducing the risk of stress concentration and damage.

[0015] Preferably, the pre-folding process based on lamination is applicable to the above-mentioned pre-folding device, and the process further comprises the following steps:
[0016] Step 1: The mounting plate is rotated to a use state away from the top of the fixed plate, and the loading robot lowers the flexible screen to a preset height position above the fixed plate, so that the two electric telescopic rods move closer to each other, so that the two moving rods move to the preset position, and the two clamping plates move closer to each other to clamp the two ends of the flexible screen. The loading robot releases the flexible screen and performs a reset movement away from the device, completing the loading of the flexible screen;
[0017] Step 2: The mounting plate moves again to above the top of the fixed plate and rises to a preset height position, the second connecting member rises upward to a preset height position, and the two moving rods move closer to each other and the first rotating motor drives the moving rod to rotate, so as to complete the automatic pre-folding of the flexible screen; in the process of pre-folding the flexible screen, a first connecting member on the mounting plate moves to a preset position, and the second electric lifting rod extends downward so that the roller abuts against the surface of the flexible screen, and the device cooperates with the pre-folding of the flexible screen. The first connecting member continues to move downward, and a downward force is applied from the middle part of the flexible screen, which is beneficial for the device to release the stress of the flexible screen during the pre-folding process;
[0018] Step 3: Then, the first connecting piece moves left and right on the mounting plate, and the camera installed on the wind plate can detect the surface of the flexible screen to detect whether the flexible screen has quality damage after pre-folding. After the detection is completed, the detection result is transmitted to the background control system, and then the mounting plate leaves the top of the fixed plate again, and the unloading manipulator unloads the flexible screen, and according to the detection of the flexible screen after pre-folding by the device, the flexible screen is classified and unloaded, thereby increasing the convenience of using the device;
[0019] Step 4: The ion fan connected to the wind plate is started to blow air to the surface of the flexible screen to blow off the dust on the surface of the flexible screen. The second rotating motor drives the second connecting piece to rotate so that the flexible screen flips over, and the wind plate blows air to complete the cleaning of the surface of the flexible screen. In addition, during the process of the device treating the flexible screen, the wind plate continuously blows air to increase the air circulation at the flexible screen, cool down the flexible screen and keep it dry, so as to prevent the flexible screen from being affected by the external temperature and humidity.
[0020] Step 5: The electric extension rod moves to a preset position, and the electric extension rod extends upward. The first vacuum suction cup can be adsorbed on the bottom of the flexible screen. The electric extension rod and the first vacuum suction cup can support the flexible screen. The mounting plate moves to a preset position above the fixed plate, and the first connecting member moves downward until the roller abuts against the upper surface of the flexible screen. The first connecting member moves along a preset trajectory on the mounting plate, and the roller rolls on the surface of the flexible screen. When the surface of the flexible screen is uneven, the roller at the protrusion will be squeezed, so that the lifting block moves toward the upper part of the fourth slot, and the spring telescopic rod is squeezed during the movement. The spring telescopic rod squeezes the pressure sensor, and then the measured pressure value is transmitted to the background control system for comparison. If the measured pressure difference exceeds the preset pressure difference, it means that the flexible screen is uneven.
[0021] Step six: The third rotating motor drives the rotating rod to rotate, so that the second vacuum suction cup rotates to a vertical downward state, and the second electric lifting rod extends downward until the second vacuum suction cup abuts against the surface of the flexible screen. The second vacuum suction cup adsorbs the flexible screen, and the splint releases the flexible screen. The electric extension rod moves downward, and the second electric lifting rod moves upward. At this time, the flexible screen after the first vacuum suction cup and the second vacuum suction cup are bonded generates a pulling force in the opposite direction, and the first tension sensor and the second tension sensor detect the pulling force and transmit it to the background control system. When the tension value reaches the preset tension value, stop pulling the flexible screen, observe the changes in the flexible screen, complete the peeling test after the flexible screen is bonded, and detect the bonding stability of the flexible screen.
[0022] Compared with the prior art, the present invention has the following beneficial effects:
[0023] In the present invention, a moving rod and a clamping plate are provided. After the loading of the flexible screen is completed, the flexible screen can be clamped and fixed by the clamping plate. Then, the moving rod is moved and rotated on the fixed plate to complete the automatic pre-folding of the flexible screen. This can not only reduce the labor of the staff, but also avoid the contamination of the surface of the flexible screen caused by the manual operation of the staff, which increases the subsequent workload.
[0024] In the present invention, by providing a first connecting member and a mounting block, during the process of pre-folding the flexible screen, when the roller abuts against the surface of the flexible screen, the first connecting member continues to move downward in cooperation with the device for pre-folding the flexible screen. This operation mode can assist the flexible screen when the device pre-folds the flexible screen, and can apply a downward force from the middle part of the flexible screen, which is beneficial for the device to release stress on the flexible screen during the pre-folding process.
[0025] The roller rolls on the surface of the flexible screen. When the surface of the flexible screen is uneven, the roller at the protrusion will be squeezed, causing the lifting block to move toward the upper inside of the fourth slot, squeezing the spring telescopic rod during the movement. The spring telescopic rod will squeeze the pressure sensor, and then the measured pressure value will be transmitted to the background control system for comparison. If the measured pressure difference exceeds the preset pressure difference, it means that the flexible screen is uneven, and the flexible screen is turned over by the second connecting piece. Then, the two sides of the flexible screen can be tested according to the above-mentioned operating steps. Through this operation method, the flatness of the flexible screen can be tested.
[0026] In the present invention, by providing a first vacuum suction cup and a second vacuum suction cup, when the device performs a flatness test on the flexible screen, the flexible screen can be supported and stabilized by the first vacuum suction cup, thereby increasing the accuracy of the detection result of the device;
[0027] The second vacuum suction cup is adsorbed on the surface of the flexible screen, and combined with the way the first vacuum suction cup adsorbs the other side of the flexible screen, the two are then pulled in opposite directions. The tension is detected by the second tension sensor and the first tension sensor, and then the state of the flexible screen is observed. The peeling test of the flexible screen can be completed, and the stability of the flexible screen after bonding can be detected.
[0028] In the present invention, a wind plate is provided, and the first connecting part is moved on the surface of the flexible screen. At this time, the ion blower connected to the wind plate is started, and air can be blown to the surface of the flexible screen. By blowing air to the flexible screen, dust on the surface of the flexible screen can be blown off, and the surface of the flexible screen can be cleaned. In the process of the device treating the flexible screen, the continuous blowing of the wind plate can increase the air circulation at the flexible screen, and the flexible screen can be cooled and kept dry, thereby preventing the flexible screen from being affected by the external temperature and humidity, and ensuring the treatment effect of the device on the flexible screen.

[0050] Step 1: The mounting plate 3 is rotated to a use state away from the top of the fixed plate 1, and the loading robot lowers the flexible screen to a preset height position above the fixed plate 1, so that the two electric telescopic rods 6 move closer to each other, so that the two moving rods 7 move to the preset position, and the two clamping plates 13 move closer to each other to clamp the two ends of the flexible screen. The loading robot releases the flexible screen and performs a reset movement away from the device, completing the loading of the flexible screen;

[0052] Step 3: Then, by moving the first connecting member 4 left and right on the mounting plate 3, the camera installed on the wind plate 30 can detect the surface of the flexible screen to detect whether the flexible screen has quality damage after pre-folding. After the detection is completed, the detection result is transmitted to the background control system. Then, the mounting plate 3 leaves the top of the fixed plate 1 again, and the unloading manipulator unloads the flexible screen. According to the detection of the flexible screen after pre-folding by the device, the flexible screen is classified and unloaded, thereby increasing the convenience of using the device;

The first connecting member 4 moves along a preset trajectory on the mounting plate 3, and the roller 37 rolls on the surface of the flexible screen. When the surface of the flexible screen is uneven, the roller 37 at the protrusion will be squeezed, so that the lifting block 36 moves toward the upper part of the fourth slot 41, and the spring telescopic rod 45 is squeezed during the movement.

If the measured pressure difference exceeds the preset pressure difference, it means that the flexible screen is uneven.
[0055] Step six: The third rotating motor 28 drives the rotating rod 29 to rotate, so that the second vacuum suction cup 34 rotates to a vertical downward state, and the second electric lifting rod 27 extends downward until the second vacuum suction cup 34 abuts against the surface of the flexible screen. The second vacuum suction cup 34 adsorbs the flexible screen, and the clamp 13 releases the flexible screen. The electric extension rod 5 moves downward, and the second electric lifting rod 27 moves upward. At this time, the flexible screen after the first vacuum suction cup 18 and the second vacuum suction cup 34 are bonded generates a pulling force in the opposite direction, and the first tension sensor 21 and the second tension sensor 39 detect the tension and transmit it to the background control system. When the tension value reaches the preset tension value, stop pulling the flexible screen, observe the changes in the flexible screen, complete the peeling test after the flexible screen is bonded, and detect the bonding stability of the flexible screen.
[0056] When the present invention is in use, the electrical equipment used in the device is powered by an external power supply through a wire. The device controls the electrical equipment in the device by setting a control system. The first vacuum suction cup 18 and the second vacuum suction cup 34 used in the device are both existing mature technologies, and are both connected to the vacuum pump through a conduit for use, so they will not be elaborated on in detail. The first tension sensor 21, the second tension sensor 39 and the pressure sensor 44 used in the device are all existing mature technologies, so they will not be elaborated on in detail. A loading robot and a unloading robot are preset above the top of the fixed plate 1. When the device is loading and unloading, the first electric lifting rod 2 is driven to rotate by a rotating motor until the mounting plate 3 rotates to a use state away from the top of the fixed plate 1, so that the mounting plate 3 will not affect the loading and unloading of the flexible screen by the device, and the wind plate 30 is connected to the ion blower preset outside the device through a conduit.
[0057] When the device is in use, the mounting plate 3 is rotated to a use state away from the top of the fixed plate 1. At this time, the loading robot lowers the flexible screen to a preset height position above the fixed plate 1, and then the first electric slider 9 slides in the first slide groove 8, so that the two electric telescopic rods 6 move closer to each other, and the two moving rods 7 move closer to the flexible screen. When moving to the preset position, the third electric slider 24 slides in the third slide groove 23, so that the two clamping plates 13 move closer to each other, so that the two ends of the flexible screen can be clamped. Then the loading robot releases the flexible screen and makes a reset movement away from the device. At this time, the loading of the flexible screen is completed.
[0058] After the flexible screen is fixed, the mounting plate 3 moves again to the top of the fixing plate 1, and is raised to a preset height position by starting the first electric lifting rod 2, and then the electric telescopic rod 6 drives the second connecting member 11 to rise to a preset height position. At this time, the two moving rods 7 move closer to each other and the first rotating motor 12 drives the moving rod 7 to rotate, so that the flexible screen can be automatically pre-folded. In the process of pre-folding the flexible screen, a first connecting member 4 on the mounting plate 3 is moved to a preset position by the sliding of the fourth electric slider 26 in the fourth slide groove 25, and then the first connecting member 4 is moved downward by extending the second electric lifting rod 27 downward. When the roller 37 abuts against the surface of the flexible screen, the first connecting member 4 continues to move downward in cooperation with the pre-folding of the flexible screen by the device. This operation mode can play an auxiliary use effect on the flexible screen when the device pre-folds the flexible screen, and a downward force can be applied from the middle part of the flexible screen, which is beneficial for the device to release the stress of the flexible screen during the pre-folding process.
[0059] After the pre-folding of the flexible screen is completed, the roller 37 no longer abuts the surface of the flexible screen. The flexible screen is restored to the state before the pre-folding by moving the moving rod 7. Then, the first connecting member 4 is moved left and right on the mounting plate 3, so that the camera installed on the wind plate 30 can detect the surface of the flexible screen to detect whether the flexible screen has quality damage after the pre-folding. After the detection is completed, the detection result is transmitted to the background control system. Then the mounting plate 3 leaves the top of the fixed plate 1 again, and the unloading robot unloads the flexible screen. According to the detection of the flexible screen after pre-folding, the flexible screen is classified and unloaded, thereby increasing the convenience of using the device.
[0060] When the device processes the flexible screen, the first connecting member 4 moves on the surface of the flexible screen, and the ion blower connected to the wind plate 30 is started to blow air on the surface of the flexible screen. The dust on the surface of the flexible screen can be blown off by blowing air to the flexible screen. The second rotating motor 19 drives the second connecting member 11 to rotate, so that the flexible screen can be flipped, and then the wind plate 30 is used to blow air to complete the cleaning of the surface of the flexible screen. In the process of the device processing the flexible screen, the continuous blowing of the wind plate 30 can increase the air circulation at the flexible screen, cool down and keep dry the flexible screen, prevent the flexible screen from being affected by external temperature and humidity, and ensure the processing effect of the device on the flexible screen.
[0061] During the mass production of flexible screens, the flexible screen will choose to complete the quality assessment of the flexible screen by random inspection. When the flexible screen is randomly inspected, after the flexible screen is pre-folded, the second electric slider 16 slides in the second slide groove 15, so that the electric extension rod 5 moves to the preset position, and then the electric extension rod 5 extends upward so that the first vacuum suction cup 18 can be adsorbed on the bottom of the flexible screen. At this time, the electric extension rod 5 and the first vacuum suction cup 18 can support the flexible screen, and then the mounting plate 3 moves to the preset position above the fixed plate 1, and the first connecting member 4 moves downward until the roller 37 abuts against the upper surface of the flexible screen, and then the first connecting member 4 is in The mounting plate 3 moves along a preset trajectory, and the roller 37 rolls on the surface of the flexible screen. When the surface of the flexible screen is uneven, the roller 37 at the protrusion will be squeezed, so that the lifting block 36 moves toward the upper inside of the fourth slot 41, and squeezes the spring telescopic rod 45 during the movement. The spring telescopic rod 45 squeezes the pressure sensor 44, and then the measured pressure value is transmitted to the background control system for comparison. If the measured pressure difference exceeds the preset pressure difference, it means that the flexible screen is uneven, and the flexible screen is turned over by the second connecting member 11. Then, the two sides of the flexible screen can be detected according to the above-mentioned operating steps. The flatness of the flexible screen can be detected through this operation method.
[0062] Then the first connecting member 4 moves upward, so that the roller 37 no longer abuts the top of the flexible screen, and then the third rotating motor 28 drives the rotating rod 29 to rotate, so that the second vacuum suction cup 34 rotates to a vertical downward state, and the second vacuum suction cup 34 moves to a preset position by sliding the moving slider 32 in the moving slide groove 31, and then extends downward through the second electric lifting rod 27 until the second vacuum suction cup 34 abuts against the surface of the flexible screen, and then the second vacuum suction cup 34 adsorbs the flexible screen, the clamping plate 13 releases the flexible screen, the electric extension rod 5 moves downward, and the second electric lifting rod 27 moves upward. At this time, the flexible screen after the first vacuum suction cup 18 and the second vacuum suction cup 34 are bonded generates a pulling force in the opposite direction, and the first tension sensor 21 and the second tension sensor 39 detect the pulling force and transmit it to the background control system. When the pulling force value reaches the preset pulling force value, the pulling of the flexible screen is stopped, and then the changes of the flexible screen are observed. Through this operation mode, the peeling test after the flexible screen is bonded can be completed, and the bonding stability of the flexible screen can be detected.
