Description

A LED display module silicone flatness testing tool

technical field

The utility model relates to the quality detection of LED display screen modules, in particular to a testing tool for the flatness of silica gel of LED display screen modules.

Background technique

In the manufacture of the LED display module, after the process of filling and curing the silica gel, it is necessary to detect the flatness of the silica gel poured on the LED display module. However, due to the dense arrangement of LED lights, the space is narrow, and the silicone is soft, which brings inconvenience to the flatness detection of silicone.

There is no good way to measure whether the height of the rubber surface of the entire module is level and whether the height is up to standard, and no quantitative data can be obtained. Conventional measuring tools, such as vernier calipers, height gauges, micrometers, ordinary rulers, etc., cannot conveniently and effectively measure the silicone height of the module. In the past, the smoothness of the silica gel poured into the LED module could only be judged by visual inspection, which would make the quality of the product unable to be effectively controlled, resulting in large differences.

Utility model content

Aiming at the defects in the prior art, the utility model provides a testing tool for the flatness of the silica gel of the LED display module, which can solve the problem of conveniently and effectively measuring the flatness of the silica gel of the LED display module.

To achieve the above object, the technical solution of the utility model is:

A tool for testing the flatness of silicone for an LED display module, including a bracket and a test pin. The main part of the bracket is a rectangular metal sheet, and a plurality of test pin sockets are arranged at equal intervals in the width direction of the rectangular metal sheet. It can slide freely in the test needle socket. In order to prevent the test needle from slipping out of the test needle socket, the upper end of the test needle is provided with a "one"-shaped upper limit cap perpendicular to the length direction of the test needle, and the lower end of the test needle is provided with a The "one"-shaped lower limit cap perpendicular to the length direction of the test needle.

A number of rectangular teeth corresponding to the number of test needles are extended above the bracket along the length direction of the test needle. There are scale lines on the rectangular teeth, and an indicator strip is set on the test needle corresponding to the position of the scale line of the rectangular teeth. When the lines are flush, the test needle indicator bar points to the zero scale position of the scale line.

The utility model is beneficial in that:

When the test tool is used to detect the flatness of the LED display module silica gel, the test tool can be conveniently embedded into the LED display module lamp surface after the glue filling and curing are completed, and the test reference line of the bracket can be aligned with the silica gel. When the test tool is moved along the length direction of the test tool, the test needle set on the test tool can move up and down with the unevenness of the silicone surface. By observing the scale corresponding to the indication bar on the test needle The position of the line can easily read the magnitude of the unevenness of the silicone surface, so that products with unqualified flatness can be easily detected.

Detailed ways

As shown in FIG. 1 , a silicone flatness testing tool 3 for an LED display module includes a bracket 1 and a test pin 2 . The main part of the bracket 1 is a rectangular metal sheet, and a plurality of test pin sockets 11 are arranged at equal intervals in the width direction of the rectangular metal sheet. Test needle 2, the test needle 2 can slide freely in the test needle socket 11, in order to prevent the test needle 2 from slipping out of the test needle socket 11, a "one" perpendicular to the length direction of the test needle 2 is provided on the upper end of the test needle 2 The font-shaped upper limit cap 211 is provided with a "one"-shaped lower limit cap 212 perpendicular to the length direction of the test needle 2 at the lower end of the test needle 2 .

On the top of the bracket 1, a number of rectangular teeth 12 corresponding to the number of test needles 2 are extended along the length direction of the test needle 2. The rectangular teeth 12 are provided with a scale line 121, and the test needle 2 is provided with an indicator bar 22 corresponding to the position of the scale line 121 of the rectangular teeth 12. When the lower edge of the lower limit cap 212 is flush with the test reference line 13 of the bracket 1 , the indicator bar 22 of the test needle 2 points to the zero scale position of the scale line 121 .

As shown in Figure 1 or Figure 2, when the test tool 3 is used to test the flatness of the LED display module silica gel, the test tool 3 can be easily embedded into the LED display module lamp after the glue filling and curing are completed. surface 4, and make the test reference line 13 of the support 1 flush with the silica gel surface 41, when the test tool 3 is moved along the length direction of the test tool 3, the test needle 2 provided on the test tool 3 can follow the The unevenness of the silicone surface 41 moves up and down. By observing the position of the scale line 121 indicated by the indicator bar 22 on the test needle 2, the magnitude of the unevenness of the silicone surface 41 can be easily read, so that it can be easily detected. Products with unqualified flatness of silica gel.
