Description

Technical Field

[0001] The present invention relates to the field of optoelectronic devices, and particularly to an optoelectronic detection device for the flatness of a module. Background Art

[0002] When assembling a backlight module, high precision is required for the backplane. Since the backlight module is a precision product, if the flatness of the backplane of the backlight module is unqualified, it is very difficult to assemble during installation, resulting in unevenness. Therefore, it is necessary to detect the flatness of the backlight module. Currently, for the flatness test of the module, ordinary jigs are used in combination with feeler gauges for limited spot checks, or 100% full inspections with low efficiency. The defective detection rate is relatively low, and at the same time, the secondary appearance pollution rate of the module caused by human contact is increased.

[0003] Therefore, in order to achieve 100% full inspection of the module flatness on the production line, improve the inspection efficiency and reduce the number of times of human contact with the product, and reduce the secondary pollution of the appearance. A new detection device is needed for automatic classification detection. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] As Figures 1 to 3 shown:

[0023] The flatness optoelectronic detection device for the module includes a base 1, a slide rail 2, a mounting bracket 3, a support plate 5, a fixed frame 6 and a laser plate 9;

[0024] Two bases 1 are arranged side by side. The base 1 is of a strip structure. A slide rail 2 is installed on the base 1. The mounting bracket 3 is slidably installed on the slide rail 2. A positioning column 20 is provided at the bottom of the mounting bracket 3. A positioning hole is opened in the positioning column 20, and a support rod 21 is inserted into the positioning hole. The support rod 21 supports the bottom of the fixed frame 6.

[0025] Among them, in this embodiment, the fixed frame 6 is formed by enclosing two first horizontal plates 7 and two second horizontal plates 8;

[0026] The two first horizontal plates 7 are arranged oppositely. The length direction of the first horizontal plate 7 is the same as the length direction of the slide rail 2. The two second horizontal plates 8 are respectively installed at both ends of the first horizontal plate 7. The second horizontal plate 8 is located between the two first horizontal plates 7. At least one limit hole 10 is respectively opened along the length direction of the first horizontal plate 7.

[0027] A detection hole 4 is opened at the bottom of the mounting bracket 3. The length direction of the fixed frame 6 is the same as the length direction of the slide rail 2. Limit holes 10 are respectively opened on both sides of the fixed frame 6;

[0028] A laser plate 9 is arranged between the two bases 1. The laser plate 9 is located below the mounting bracket 3;

[0029] Meanwhile, a waste box 19 is installed between two strip-shaped bases 1, and the waste box 19 is arranged adjacent to the mounting bracket 3.

[0030] The limiting device is installed on the mounting bracket 3. The limiting device includes a limiting cylinder 11, a limiting housing 12, a limiting spring 13, a sliding block 14, a connecting rod 15 and a supporting piece 16.

[0031] The supporting plate 5 is installed on the mounting bracket 3, the limiting housing 12 is installed on the supporting plate 5, the sliding block 14 is installed in the limiting housing 12, the first end of the connecting rod 15 is connected to the inner end of the sliding block 14, the second end of the connecting rod 15 extends out of the limiting housing 12 and is connected to the telescopic end of the limiting cylinder 11. The limiting spring 13 is sleeved on the connecting rod 15, and the limiting spring 13 is located between the sliding block 14 and the bottom of the limiting housing 12.

[0033] The working principle of the present invention: When the backlight module is not placed in the fixed frame, the limiting cylinders located on both sides of the fixed frame respectively push the sliding air blocks through the corresponding connecting rods, so that the supporting pieces extend into the fixed frame from the limiting holes. The mechanical gripper of the previous process grabs the backlight module into the fixed frame and is supported by the supporting pieces. The pushing and pulling device drives the mounting bracket to slide on the slide rail to the upper part of the laser plate. A detection hole is opened at the bottom of the mounting shell, and laser ranging is performed on the back of the backlight module through the laser plate dot matrix. The laser plate sends the collected data to the processing system for judgment. If the data of the laser ranging is unqualified, the pushing and pulling device drives the mounting bracket to slide above the waste box, and the limiting cylinder pulls the connecting rod, so that the sliding block drives the supporting piece to withdraw from the limiting hole, and the backlight module falls into the waste box under the action of gravity.
