Technical Field

[0001] The utility model relates to the technical field of LED detection, in particular to a scale for querying the coordinates of crooked lamps of an LED module. Background Art

[0002] With the rapid development of LED display technology, small-pitch LED displays have gradually become the mainstream products in the market with their high resolution and high definition. In particular, small-pitch LED displays below P2.5 have a wide range of applications including commercial advertising, indoor conference displays, high-definition TV walls, etc., and their market size continues to expand. However, small-pitch LED modules face many technical challenges during the production process.

[0003] Among them, the mounting of LED lamp beads is a key link in module production. Due to the small pitch of the small-pitch LED module and the large number of LED lamp beads per unit area, each module may need to mount tens of thousands of LED lamp beads. During the production process, due to problems with machinery and equipment, materials, or improper operation, LED lamp beads often appear misplaced, tilted, or randomly mounted, which is the so-called "leaking crooked lamps".

[0004] The traditional method of analyzing the missing or crooked lamps mainly relies on manual counting of lamps, and by confirming the X and Y coordinate positions of the missing or crooked lamps on the module, it is possible to track and confirm which machine or nozzle caused the defect. However, due to the high density and large number of lamp beads in small-pitch LED products, manual counting of lamps often results in miscounting, which not only increases the difficulty of troubleshooting, but also prolongs the time to handle the abnormality, seriously affecting the production efficiency of the production line.

[0005] To this end, those skilled in the art have proposed a scale for querying the coordinates of the crooked lamps of an LED module to solve the problems raised by the background technology. Utility Model Content

[0007] A scale for querying the coordinates of a crooked lamp of an LED module comprises a first baffle, a plurality of first measuring scales are fixedly connected to the outer side wall of the first baffle, and a connection groove is provided on the inner side walls of the plurality of first measuring scales;

[0008] An extension mechanism, wherein the extension mechanism is arranged on the inner side wall of the connecting groove;

[0009] The limiting mechanism is arranged on the outer side wall of the first measuring ruler.

[0010] Preferably, the extension mechanism comprises a second measuring ruler, the second measuring ruler is in the form of a plurality of inner side walls slidably connected to a plurality of connecting grooves, and a second baffle is fixedly connected to an outer side wall of the second measuring ruler.

[0011] Preferably, the limiting mechanism includes a limiting slot, which is provided on the outer side wall of the first measuring ruler, and the outer side wall of the second measuring ruler is provided with a plurality of connecting slots, the inner side wall of the limiting slot is slidably connected with a sliding rod, the outer side wall of the sliding rod is fixedly connected with a limiting slide, and two supporting springs are fixedly connected to both ends of the outer side of the limiting slide.

[0012] Preferably, the connection slots are evenly spaced on the outer side wall of the second measuring ruler, the two support springs are also fixedly connected to the outer side wall of the first measuring ruler, and the sliding clamp rod is also snap-connected to the outer side wall of the second measuring ruler.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The scale of the utility model can quickly and accurately determine the X and Y coordinates of the missing crooked lamps on the LED module. Compared with the traditional manual counting method, the scale of the patent is easy to operate and not prone to errors, which greatly improves the efficiency of troubleshooting and handling abnormalities and effectively shortens the production line production cycle.

[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] As attached Figure 1 To Attachment Figure 3 As shown:

[0023] Embodiment 1: The utility model provides a scale for querying the coordinates of the LED module's leaking crooked lamp, comprising a first baffle 1, the outer side wall of the first baffle 1 is fixedly connected with a plurality of first measuring scales 11, and the inner side walls of the plurality of first measuring scales 11 are provided with connecting grooves 12;

[0024] An extension mechanism, the extension mechanism is arranged on the inner side wall of the connecting groove 12;

[0025] The limiting mechanism is arranged on the outer side wall of the first measuring ruler 11 .

[0026] The extending mechanism comprises a second measuring ruler 2 , wherein the second measuring ruler 2 is in the form of a plurality of inner side walls slidably connected to a plurality of connecting grooves 12 , and a second baffle 21 is fixedly connected to an outer side wall of the second measuring ruler 2 .

[0027] Specifically, by setting the second measuring ruler 2, the length of the first measuring ruler 11 can be extended, so that a larger number of lamp beads can be measured conveniently without changing the equipment.

[0028] The limiting mechanism includes a limiting slot 23, which is provided on the outer wall of the first measuring ruler 11, and a plurality of connecting slots 22 are provided on the outer wall of the second measuring ruler 2. A sliding rod 24 is slidably connected to the inner wall of the limiting slot 23, and a limiting slide 26 is fixedly connected to the outer wall of the sliding rod 24. Two supporting springs 25 are fixedly connected to the two ends of the outer side of the limiting slide 26.

[0029] Specifically, through the connection between the support spring 25 and the limiting slide plate 26 , a force can be applied to the limiting slide plate 26 , so that the limiting slide plate 26 presses the sliding card rod 24 , so that the sliding card rod 24 and the connecting card slot 22 are engaged together.

[0030] The connecting slots 22 are evenly spaced on the outer wall of the second measuring ruler 2 , the two supporting springs 25 are also fixedly connected to the outer wall of the first measuring ruler 11 , and the sliding lever 24 is also engaged and connected to the outer wall of the second measuring ruler 2 .

[0031] As can be seen from the above, when it is necessary to measure the lamp beads, first place the scale parallel to the surface of the module, and there is a gap between the scale and the lamp beads on the surface of the module to avoid contact with the lamp surface and causing the lamp beads to scatter. According to the position displayed by the positioning ruler, the X and Y coordinates of the missing lamp can be obtained: each model has two scales of length and width, the long side is detected as the coordinate point of the placement machine X, and the wide side is detected as the coordinate point of the placement machine Y. If the measurement scale needs to be adjusted, first pull the connecting bracelet 27 to allow the connecting bracelet 27 to drive the sliding card rod 24 to disengage from the connecting card slot 22 through the limiting slide 26, and then pull the second baffle 21 to allow the second baffle 21 to drive the second measuring ruler 2 to slide out in the first measuring ruler 11. Release the connecting bracelet 27 while sliding. When the next connecting card slot 22 slides to a suitable position, the support spring 25 will pull the limiting slide 26 to allow the sliding card rod 24 to re-engage in the connecting card slot 22 to limit the second measuring ruler 2.
