Description

Technical Field

[0001] This utility model relates to the field of LCD screen repair, and more particularly to an LCD screen testing and repair device. Background Technology

[0002] LCD screen repair devices use laser technology to precisely repair panels. For example, laser repair equipment can be used to treat defects such as short circuits, colored lines, and black lines on LCD panels.

[0003] However, during the repair process, it is necessary to inspect the appearance of the LCD screen and locate the defects. Traditional repair and inspection are carried out by two separate machines, which takes up a lot of space. At the same time, an additional handling mechanism is needed to complete the one-way transportation of the LCD screen. In addition, the LCD screen is large in size and the LCD structure has weak vibration resistance, which places very high demands on the handling mechanism. Utility Model Content

[0004] To address the aforementioned issues, this invention provides a liquid crystal screen detection and repair device that integrates defect detection and repair functions, thus resolving the problems of large space occupation and increased costs due to additional handling mechanisms.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is: a liquid crystal screen detection and repair device, comprising a worktable that supports the liquid crystal screen, the worktable having a work surface and a linear moving mechanism that provides spatial dimension changes, characterized in that the movable end of the linear moving mechanism integrates a collection unit of an appearance defect detection mechanism and a laser repair mechanism, the relative position between the collection unit and the laser repair mechanism being fixed.

[0006] The beneficial effects of this utility model are:

[0007] This invention employs an integrated solution, combining the appearance defect detection mechanism and the laser repair mechanism into a single linear moving mechanism. Specifically, the relative positions of the two are fixed. Knowing the fixed distance, repairing the defect area only requires compensating the laser repair mechanism for this distance, ensuring a point-to-point relationship between the laser repair mechanism's execution end and the defect area. As a result, this invention combines the functions of two different mechanisms and reduces the number of devices to a single unit. Therefore, its small space requirement allows for increased overall repair efficiency within a limited space by increasing the number of devices. Simultaneously, it eliminates the need for a handling mechanism, optimizing production costs.

[0008] The working surface is flat. After the LCD screen falls onto the flat surface, the air between the working surface and the LCD screen will be squeezed out. In order to remove the LCD screen smoothly, an air blowing device is installed around the working surface. The output end of the air blowing device is facing the LCD screen. The air blowing device releases positive pressure airflow. The positive pressure airflow will flow in from the gap between the LCD screen and the working surface, eliminating the suction effect of negative pressure and allowing the LCD screen to be easily separated from the working surface.

[0009] The specific method for detecting defects in appearance involves the acquisition unit obtaining pattern information from the LCD screen. This pattern information is then sent to a computer, where it is compared with pre-set pattern comparison data to determine whether a defect exists on the LCD screen. For example, if the distance between the acquisition unit and the laser repair mechanism is 5cm, when an appearance defect is encountered, the linear moving mechanism drives the laser repair mechanism and the acquisition unit to shift by 5cm. At this point, the output repair end of the laser repair mechanism can then correspond to the defective area of ​​the LCD and repair it.

[0010] Specifically, the aforementioned laser repair mechanism is an existing laser repair machine, in which the laser head emits a laser to repair the defective area.

[0011] The aforementioned linear motion mechanism is an existing three-axis mechanism that includes position changes in the X, Y, and Z directions; its structure will not be described in detail here. Attached Figure Description

[0012] Figure 1 This is a perspective view of the present invention.

[0013] Figure 2 yes Figure 1 Enlarged diagram of point A. Detailed Implementation

[0014] like Figure 1-2 As shown, a liquid crystal screen inspection and repair device includes a worktable 1 that supports a liquid crystal screen 5. The worktable 1 has a work surface 100 and a linear moving mechanism 200 that provides spatial dimension changes. The device is characterized in that the movable end of the linear moving mechanism 200 integrates a collection unit 300 for appearance defect detection and a laser repair mechanism 400. The relative position between the collection unit 300 and the laser repair mechanism 400 is fixed.

[0015] The beneficial effects of this utility model are:

[0016] This invention employs an integrated solution, combining the appearance defect detection mechanism and the laser repair mechanism 400 into a single linear moving mechanism 200. Specifically, the relative positions of the two are fixed. Knowing the fixed distance, repairing the defective area only requires compensating the laser repair mechanism 400 for this distance, ensuring a point-to-point relationship between the laser repair mechanism 400's execution end and the defective area. As a result, this invention integrates the functions of two different mechanisms and reduces the number of devices to one. Therefore, its small space requirement allows it to improve overall repair efficiency within a limited space by increasing the number of devices. Simultaneously, it eliminates the need for a handling mechanism, optimizing production costs.

[0017] The working surface 100 is a flat surface. After the LCD screen 5 falls onto the flat surface, it will squeeze out the air between the working surface 100 and the LCD screen 5. In order to remove the LCD screen smoothly, an air blowing device 61 is provided around the working surface 100. The output end of the air blowing device 61 faces the LCD screen 5. The air blowing device 61 releases positive pressure airflow. The positive pressure airflow will flow in from the gap between the LCD screen 5 and the working surface 100, eliminating the suction effect of negative pressure and allowing the LCD screen 5 to be easily separated from the working surface 100.

[0018] The specific method for detecting appearance defects involves the acquisition unit 300 acquiring pattern information from the LCD screen 5. This pattern information is then sent to a computer, where it is compared with pre-set pattern comparison data to determine whether a defect exists on the LCD screen 5. For example, if the distance between the acquisition unit 300 and the laser repair mechanism 400 is 5cm, when an appearance defect is encountered, the linear movement mechanism 200 drives the laser repair mechanism 400 and the acquisition unit 300 to shift by 5cm. At this time, the output repair end of the laser repair mechanism 400 can then correspond to the defective area of ​​the LCD and repair it. In other words, the movement paths of the acquisition unit 300 and the laser repair mechanism 400 overlap.

[0019] Specifically, the aforementioned laser repair mechanism 400 is an existing laser repair machine, in which the laser head emits a laser to repair the defective area.

[0020] The aforementioned linear motion mechanism 200 is an existing three-axis mechanism that includes position changes in the X, Y, and Z directions; its structure will not be described in detail here.

[0021] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model.
