In the related art, the repair of the OLED screen is generally achieved using a laser repair technique. The laser unit for generating laser is arranged on the movable portal frame in a sliding mode, the laser unit can move in a first direction through the movement of the portal frame, and can move in a second direction through the movement of the sliding base connected with the cross beam of the portal frame in a sliding mode, so that the alignment process of the laser unit and defects on the OLED screen body is achieved, and therefore the repairing method can be called as an active laser repairing method of the laser unit.

The active alignment process of the laser unit has many problems. The problem that the repair effect of the OLED screen body is most easily affected is that the gantry is heavy, and laser units on the gantry are prone to violent shaking or vibration in the moving process, so that the alignment accuracy of the laser units and the OLED screen body is reduced. In addition, the efficiency/effect of laser repair of the OLED screen is reduced due to the problems that more electric energy is consumed for driving the heavy gantry to move frequently, the displacement precision of the gantry relative to the movement of the OLED screen is small, the consumed time of a single gantry moving among a plurality of OLED screens is long, and the like.

In order to solve the above problems, the present embodiment provides a lighting mechanism follow-up type OLED panel laser repairing method, in which defects on the OLED panel are aligned with the laser unit by moving the lighting mechanism and the moving stage relative to the laser unit, that is, by moving the lighting mechanism synchronously with the moving stage, so that jitter or vibration of the laser unit is directly avoided.

Specifically, the repairing method of the present embodiment includes the following steps:

a preparation stage: the mobile carrier carrying the OLED screen body and the lighting mechanism provided with the electric contacts relatively move in a first direction and converge; after that, the movable stage and the lighting mechanism are connected.

And (3) repairing: the electrical contact lights the OLED screen body, the movable carrier and the lighting mechanism synchronously move in the first direction to enable the defects of the OLED screen body to be aligned to the laser unit in the first direction, and the relative distance between the movable carrier and the lighting mechanism and the laser unit is simultaneously adjusted in the second direction to enable the defects of the OLED screen body to be aligned to the laser unit in the second direction; and then, the laser unit finishes repairing the defects.

And (5) finishing: the movable carrier returns to the material moving position, and the lighting mechanism returns to the initial position.

It should be noted that the first direction referred to in this embodiment may be a direction in which both the movable stage and the lighting mechanism are connected, for example, an x direction indicated in the drawing; the second direction may be a direction perpendicular to the first direction and lying in the plane of motion of the moving stage, for example the y-direction as indicated in the figures; the third direction may be a direction perpendicular to the plane of movement of the moving stage, for example the z-direction as identified in the figures.

It is obvious that the first direction, the second direction, or the third direction in this embodiment is not a single direction, but two opposite directions. For example, it is not contradictory that the movement in the first direction may be either forward or backward in the first direction, i.e., the movement in the first direction may refer to movement in the x direction in the drawings or movement in the direction opposite to the x direction in the drawings.

In the repair phase, after the OLED panel is lit by the electrical contacts, in order to achieve synchronous movement of the mobile carrier carrying the OLED panel and the lighting mechanism provided with the electrical contacts in the first direction, the mobile carrier and the lighting mechanism may be connected detachably to achieve conversion between the synchronous movement and the relative movement.

The detachable connection means that the movable carrier and the lighting mechanism can be in a connected state or in a separated state. When the movable carrier and the lighting mechanism are in a separated state, the movable carrier and the lighting mechanism can perform relative motion in a first direction, so that the movable carrier can convey the OLED screen body between the laser repairing device and the upstream and downstream processes of the laser repairing device; when the movable stage and the lighting mechanism are in a connected state, the movable stage and the lighting mechanism may be moved synchronously in the first direction.

It should be noted that the synchronous movement in this embodiment means that when the movable stage and the lighting mechanism move in the first direction at the same time, the movable stage and the lighting mechanism are kept relatively still in the first direction, so as to ensure that the electrical contact of the lighting mechanism and the OLED panel maintain stable electrical connection, and prevent the electrical contact and the OLED panel from short circuit, disconnection and poor contact, thereby preventing the OLED panel from being unable to be repaired.

In order to ensure the stability of the electrical connection between the electrical contact and the OLED panel, the moving stage and the lighting mechanism are connected while being positioned and limited, so that the movement of the moving stage and the lighting mechanism in the first direction is completely synchronous. Therefore, the separable connection mode between the movable carrier and the spot light mechanism can be electromagnetic connection, can also be connection realized through a zero point positioning mechanism, and can also be connection through other connection modes such as snap connection, interference connection, pin connection and the like.

When the movable stage and the lighting mechanism are in a connected state, the synchronous movement of the movable stage and the lighting mechanism in the first direction can be realized by pulling/pushing the lighting mechanism through the movable stage, or can be realized by pulling/pushing the movable stage through the lighting mechanism. Further, the moving stage and the lighting mechanism may be moved, respectively, and the speeds in the first direction of both may be controlled to be the same.

In order to realize the movement of the movable stage and the lighting mechanism in the second direction, the movable stage and the lighting mechanism may be provided on the same first slide rail and formed as a follower module. At this time, the position of the OLED screen body in the second direction can be adjusted by moving the follower module in the second direction, so that the defect on the OLED screen body is aligned with the laser unit in the second direction.

In order to implement the repair method provided above, the present embodiment provides a corresponding OLED panel laser repair system.

In the following, the following description is given,

Specifically, the lighting slider 1234 is provided with a support arm 1231, the support arm 1231 is provided with a lift arm 1232 in a sliding manner, and the electrical contact 1233 is provided on the lift arm 1232. The lifting arm 1232 is specifically driven by a lifting driver provided on the support arm 1231 or the lighting slider 1234, and the lifting driver may be one of an air cylinder, a hydraulic cylinder, and a motor, and is not particularly limited as long as the lifting arm 1232 can slide in the third direction.

After the movable carrier 122 is connected to the lighting mechanism 123, the electrical contact 1233 is located above the OLED panel, and at this time, the lifting driving member drives the lifting arm 1232 to move toward the OLED panel, so that the electrical contact 1233 is in contact with the OLED panel to achieve electrical connection.

Fig. 3 shows a specific structure of the moving stage 122 in this example. Specifically, the moving stage 122 may include a stage slide 1224, a first connector 1226, and a bearing surface 1221.

The carrying surface 1221 is provided with a plurality of placing positions 1222, the different placing positions 1222 have different sizes, but all the placing positions 1222 close to the lighting mechanism 123 are aligned, so that the electrical contacts 1233 can conveniently light the OLED screens with different sizes. A supporting edge 1223 may be disposed on a side of the supporting surface 1221 close to the lighting mechanism 123, and the supporting edge 1223 may be disposed to protrude from the supporting surface 1221, and is used for placing an edge of the OLED screen contacting the electrical contact 1233. The supporting edge 1223 may be provided with micro holes for adsorbing the OLED panel.

In order to precisely adjust the relative position between the OLED panel and the electrical contact 1233, and ensure the accuracy and stability of the electrical connection between the electrical contact 1233 and the OLED panel, a fine adjustment mechanism 1225 is further disposed on the moving stage 122 in this embodiment. Specifically, the fine adjustment mechanism 1225 may be disposed on the stage sliding base 1224, the bearing surface 1221 is disposed on the moving end of the fine adjustment mechanism 1225, and the position of the bearing surface 1221 relative to the electrical contact 1233 is adjusted by the fine adjustment mechanism 1225, so as to complete fine adjustment of the position between the electrical contact 1233 and the OLED screen.

It should be noted that the specific structure of the XY θ positioning stage is not limited as long as the adjustment of the position of the bearing surface 1221 in two directions with respect to the stage slide 1224 can be achieved.

In this embodiment, the movable stage 122 and the spot light mechanism 123 may be connected by a snap connection, specifically, the connection may be realized by the connection hole 1227 and the connection protrusion 1237. A plurality of coupling claws which can move in the radial direction of the coupling protrusion 1237 are provided in the coupling hole 1227. When the connection is performed, after the connection protrusion 1237 is inserted into the connection hole 1227, the connection claws may be radially extended along the connection protrusion 1237, and the connection protrusion 1237 may be clamped by a plurality of connection claws.

In addition, the snap connection may be implemented by a zero point positioning mechanism, that is, a separable connection may also be implemented by the zero point positioning mechanism, and specifically, the zero point positioning mechanism may be a zero point positioning mechanism commonly used in the related art for implementing positioning connection of two components, for example, but not limited to, the zero point positioning device disclosed in chinese patent application No. 2019211271594, and the specific structure of the zero point positioning mechanism of this embodiment is not limited as long as the connection between the moving stage 122 and the spot light mechanism 123 can be implemented.

As an embodiment, the zero point positioning joint of the zero point positioning mechanism may be disposed on the first connecting member 1226, and the zero point positioning seat may be disposed on the second connecting member 1236; as another embodiment, the zero point positioning joint may be disposed on the second connecting member 1236, and the zero point positioning seat may be disposed on the first connecting member 1226. During connection, after the zero point positioning joint extends into the zero point positioning seat, the zero point positioning joint is clamped tightly by utilizing the zero point positioning seat through air pressure, oil pressure or mechanical force, so that the connection between the movable carrier 122 and the spot light mechanism 123 is realized.

The specific process and the corresponding principle of clamping the zero point positioning joint by the zero point positioning seat can be implemented by referring to the scheme disclosed in the related field or according to the mode suggested by manufacturers, and therefore, related contents are not repeated in the embodiment.

In order to improve the connection stability and the positioning effect between the moving stage 122 and the spot mechanism 123, the zero point positioning mechanism may be provided in more than two groups, for example, two groups, or three groups, or more groups.

Specifically, the stage driving member may be an air cylinder, a hydraulic cylinder, or a motor, and the specific type of the stage driving member is not limited. The lighting mechanism 123 is slidably connected only to the first slide rail 121. When the movable stage 122 and the lighting mechanism 123 are in a connected state, the movable stage 122 may drive the lighting mechanism 123 to slide along the first sliding rail 121; when the moving stage 122 and the lighting mechanism 123 are in the separated state, the lighting mechanism 123 stays on the first slide rail 121, and the position thereof in the first direction does not change.

When the movable stage 122 moves toward the lighting mechanism 123 while carrying the OLED panel, the movable stage 122 may contact the lighting mechanism 123, which causes the lighting mechanism 123 to move, making it difficult to accurately connect the movable stage 122 and the lighting mechanism 123. Therefore, when the moving stage 122 and the lighting mechanism 123 are in the separated state, the lighting mechanism 123 can be fixed on the first slide rail 121, thereby facilitating the connection between the moving stage 122 and the lighting mechanism 123.

Specifically, a locking hole 1235 may be formed in the lower side surface of the lighting slide holder 1234, and the locking mechanism 124, for example, the first sliding rail 121, may be disposed below the lighting slide holder 1234. By extending and contracting the lock head 1241 of the lock mechanism 124, the lock hole 1235 of the lock mechanism 124 is engaged, and the lock/release of the lighting mechanism 123 by the lock mechanism 124 is completed.

Fig. 8 shows the structure of the lock mechanism in this embodiment. Specifically, the locking mechanism 124 can include a mount 1242, and a lock drive 1243 disposed on the mount 1242. The moving end of the locking driving member 1243 is connected to the locking head 1241 for driving the locking head 1241 to extend and retract relative to the mounting seat 1242.

The locking hole 1235 may be opened on a side surface of the lighting mechanism 123 or on a top surface, for example, a side surface of the support arm 1231. The position of the locking mechanism 124 corresponds to the position of the locking hole 1235, while the locking head 1241 is extended and contracted in the direction perpendicular to the first direction.

Further, the lighting mechanism 123 may be provided with a lock head 1241, and the lock mechanism 124 for opening the lock hole 1235 may be provided at a position corresponding to the lock head 1241. For example, when the locking head 1241 is provided on the lower side of the lighting slide holder 1234 of the lighting mechanism 123, the locking mechanism 124 may be provided on the first slide rail 121 such that the locking head 1241 is provided toward the locking mechanism 124, and the locking hole 1235 may be opened in the locking mechanism 124 on a surface facing the locking head 1241.

In the following, the following description is given,

as another example of the arrangement mode of the fine adjustment mechanism 1225, the fine adjustment mechanism 1225 may be arranged on the lighting mechanism, and thus the position between the OLED panel and the electrical contact 1233 may be adjusted by adjusting the lighting mechanism 123 by the fine adjustment mechanism 1225.
