[0003] When using a fully transparent display screen in strong outdoor light, the ambient light makes the backlight appear to be seriously insufficient due to the excessive brightness of the sunlight. Simply relying on increasing the backlight brightness to achieve visibility in the sun will increase power consumption, rapidly lose power, and cause users to worry about battery life. This phenomenon also occurs in organic electromechanical laser displays.

[0005] The reflective effect of the semi-reflective and semi-transparent display is not as good as the full reflective effect; the transmittance is much lower than the full transparent display. When the external light is insufficient, turning on the backlight will consume more power than the full transparent display. The cost will also be higher.

When producing a touch display screen with more functional layers, different functional layers need to be frequently pasted, and the target plate 16 is not only a single side as a production and processing area, so it needs to be flipped. The rotating frame 12 can smoothly flip the plate 16 fixed by the suction cup 15.

[0053] Advantageously, a mounting groove 35 is provided on one side of the rotating frame 12, a control motor 28 is fixedly provided in the mounting groove 35, a driving gear 27 is fixedly provided on the output shaft of the control motor 28, a transmission gear 31 is provided on one side of the driving gear 27, the transmission gear 31 is meshed with the driving gear 27, the transmission gear 31 is fixedly provided on a control shaft 32, and the control shaft 32 is rotatably connected to the rotating frame 12.

[0058] Advantageously, an adjustment motor 26 is fixedly provided at one end of the fixed sleeve 25 close to the plate 16, the output shaft of the adjustment motor 26 passes through the fixed sleeve 25, a control gear is rotatably provided in the fixed sleeve 25, the control gear is fixedly connected to the output shaft of the adjustment motor 26, two adjustment rods 19 are slidably provided in the fixed sleeve 25, the two adjustment rods 19 are respectively located on both sides of the control gear, and teeth are provided at one end of the two adjustment rods 19 close to each other, and the teeth on the adjustment rods 19 mesh with the control gear.

When the suction cup 15 is close to the plate 16, the telescopic tube 23 and the buffer spring 22 with telescopic function will not cause damage to the plate 16.

[0060] An eye-protecting, energy-saving, sunlight-visible touch display screen comprises a front light source assembly and a touch display module 47 assembled together; the front light source assembly comprises a cover plate 42, a high-transmittance optical light guide plate 44 and a composite polarizer 46 attached together in sequence, and the touch display module 47 comprises a lower glass panel 56, a high-reflection layer 55, a liquid crystal layer 54, a transparent touch functional sheet 53 and an upper glass panel 52 attached together in sequence.

[0061] Advantageously, one end of the high-transmittance optical light guide plate 44 is provided with a front light source 48 and a flexible circuit board 1 50 ; one end of the lower glass panel 56 is provided with an integrated chip 49 and a flexible circuit board 2 51 .

[0062] Working principle of the present invention:

[0063] The touch screen manufacturing tooling has a symmetrical structure, and the structures on both sides are exactly the same. The structure on one side is described below. In the initial state, the suction cup structure is controlled by the robot arm to grab the plate 16 and stand by on one side of the touch screen manufacturing tooling; the rotating frame 12 is in a vertical state, and the two suction cups on the same side are close to each other.

[0064] The control motor 28 is started, and the control motor 28 controls its output shaft to rotate. The drive gear 27 rotates together with the control motor 28. The drive gear 27 drives the transmission gear 31 to rotate through meshing. The control shaft 32 rotates together with the transmission gear 31. The control shaft 32 attempts to drive the main shafts on both sides to rotate through the one-way bearings 33 on both sides. However, the installation directions of the two one-way bearings 33 are opposite, resulting in opposite directions of restricted rotation. At the same time, the control shaft 32 will only drive one of the main shafts to rotate, while the other main shaft will not rotate. By changing the rotation direction of the control shaft 32, the state of whether the two main shafts rotate can be changed.

[0065] Initially, the control motor 28 controls the upper spindle to rotate, driving the upper rotating arm 30 to rotate. After the upper rotating arm 30 rotates 90 degrees, it contacts the upper limit plate 36 and cannot continue to rotate. At this time, the control motor 28 stops working and the output shaft is locked. In this state, the two upper suction cups 15 are located on the side of the support frame 11, and the corresponding torsion springs remain in a compressed state. When the mechanical arm is used to control the plate 16 to vertically enter the specified position, it is not disturbed by the path.

[0066] After the plate 16 reaches the set position, the adjusting motor 26 on the lower side is started, and its output shaft is controlled to rotate, driving the control gear to rotate. The control gear drives the two adjusting rods 19 to move away from each other through meshing, and then drives the two buffer springs 22 to move away from each other. The two buffer springs 22 move away from each other to the edge position of the corresponding plate 16; then the control cylinder 18 on the lower side is started, and its piston rod is controlled to extend, driving the connecting plate 24 to approach the plate 16, and the connecting plate 24 drives the fixed sleeve 25 and the sliding rod 17 to move, and the sliding rod 17 and the slide groove 29 slide, and the fixed sleeve 25 drives the two adjusting rods 19 and the two buffer springs 22 to approach the plate 16, and stops when the buffer springs 22 are close to the plate 16, and the air pump is started to inhale, controlling the two buffer springs 22 to suck the plate 16. At this time, the lower side of the plate 16 has stable support and load-bearing.

[0067] When the plate 16 is the lower glass panel 56, ensure that it has a stable posture until the touch display module 47 is assembled; when the plate 16 is the high-transmittance optical light guide plate 44, first place the cover plate 42, turn over the high-transmittance optical light guide plate 44, and then place the composite polarizer 46;

[0068] When flipping, the control motor 28 is in standby mode, and its output shaft becomes free. The torsion spring on the upper side loses external force constraint and resets, driving the upper rotating arm 30 to reset, so that the two suction cups 15 on the upper side return from the side of the support frame 11 to the top of the plate 16; the same as the above principle, the adjustment motor 26, the control cylinder 18 and the air pump are started in sequence to make the upper suction cup 15 also adsorb the plate 16;

[0069] By starting the driving motor 13 to flip the rotating frame 12, the plate 16 is driven to flip 180 degrees. Then, the suction cup 15 originally on the lower side is flipped to the upper side, and it is deflated and moved to the side of the support frame 11, thereby ensuring that there is sufficient operating space when processing the other side of the high-transmittance optical light guide plate 44.

[0070] In addition, the touch screen manufacturing tooling can not only provide a stable posture for the plate 16 during bonding, but also can rotate at any angle when the suction cups 15 on both sides are adsorbed to meet the needs of welding the flexible circuit board 1 50 and the flexible circuit board 2 51, as well as the needs of brushing ink around the wick of the front light source 48.

[0071] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", "connected", etc. should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0072] The above contents are merely examples and explanations of the structure of the present invention. The technicians in this technical field may make various modifications or additions to the specific embodiments described or replace them in a similar manner. As long as they do not deviate from the structure of the invention or exceed the scope defined by the claims of the present invention, they should all fall within the protection scope of the present invention.
