Description

Technical Field

[0001] The utility model relates to the technical field of silicone potting, and more specifically, to a glue discharging mechanism of a potting machine. Background Technique

[0002] An LED display screen is a flat panel display composed of multiple small LED module panels, which is a device used to display various information such as text, images, videos, and video signals. The LED display screen is a new type of information display medium. It is a flat panel display screen that controls the display mode of light-emitting diodes and can be used to display various static information such as text and graphics, as well as various dynamic information such as animations and videos. The LED electronic display screen integrates microelectronics technology, computer technology, and information processing, and has the advantages of bright colors, wide dynamic range, high brightness, long life, stable and reliable operation, etc. It is widely used in commercial media, cultural performance markets, stadiums, information dissemination, news release, securities trading, etc., and can meet the needs of different environments. It can be divided into single-color display screens and full-color display screens according to the color primary color.

[0003] A small-pitch LED display screen is a display screen designed and manufactured using small-sized LED modules, with high pixel density and high definition. Compared with traditional LED display screens, the small-pitch LED display screen has smaller module size and closer pixel pitch, and can achieve higher resolution and finer picture effect.

[0004] The inventor believes that as LED outdoor display screens gradually expand in the P2.5 / P2 small-pitch field, the outer diameter of the potting needle has decreased from 1.3 - 2.2 mm and the inner diameter from 0.9 - 1.8 mm of large-pitch products to 0.6 - 0.8 mm and the inner diameter from 0.52 - 0.6 mm. The glue discharging design scheme of the potting machine for conventional products ( Figure 3 and Figure 4 ) has problems such as insufficient glue discharging pressure and unsmooth glue discharging. Based on the above problems, we provide a glue discharging mechanism of a potting machine.

[0005] The above information disclosed in this background technique is only used to increase the understanding of the background technique of the utility model. Therefore, it may include prior art that is not known to ordinary technicians in this field. Content of the Utility Model

[0006] In order to solve the problems of insufficient glue discharging pressure and unsmooth glue discharging in the glue discharging design scheme of the potting machine for conventional products proposed in the above background technique, the utility model provides a glue discharging mechanism of a potting machine.

[0007] The glue discharging mechanism of a potting machine provided by the utility model adopts the following technical scheme:

[0008] A glue discharging mechanism of a glue filling machine, comprising a main body plate; a diversion groove opened at the bottom of the main body plate, and the shape of the diversion groove is triangular; a plurality of glue filling needles are arranged on the top of the main body plate for filling glue for an outdoor LED display screen, and the shape of the glue filling needle is conical.

[0009] Preferably, the number of triangular shapes in the diversion groove is six.

[0010] Preferably, the inner edges of the diversion groove are all rounded.

[0011] Preferably, the glue filling needles are arranged at equal intervals.

[0012] Preferably, a plurality of connection holes are opened on the top of the main body plate.

[0013] In summary, the present utility model includes the following beneficial technical effects:

[0014] Through the design of the triangular diversion groove and the conical glue filling needle, the smooth discharge of glue for outdoor small-pitch products is realized. The triangular diversion groove can accommodate more glue, and thus a higher glue filling machine flow rate setting can be achieved. At the same time, the design of the conical glue filling needle can increase the glue discharge air pressure under the same inner and outer diameter conditions, thereby increasing the smoothness of glue discharge; through a new glue discharging design scheme, the problem of unsmooth glue discharge under the condition that the outer diameter of the glue filling needle is ≤0.6 and the inner diameter is ≥0.5 due to the reduction of the row pitch of lamp beads for outdoor small-pitch products is solved.

[0015] The above summary is only for the purpose of the specification and is not intended to be limiting in any way. In addition to the above-described illustrative aspects, embodiments, and features, further aspects, embodiments, and features of the present invention will be readily apparent by reference to the drawings and the following detailed description.

The design of the triangular diversion groove and the conical glue filling needle realizes smooth glue discharging for outdoor small-pitch products. The triangular diversion groove 2 can accommodate more glue, and thus a higher glue filling machine flow rate setting can be achieved. At the same time, the design of the conical glue filling needle 3 can increase the glue discharging air pressure under the same inner and outer diameter conditions, thereby increasing the smoothness of glue discharging.

[0024] Through a new glue discharging design scheme, the problem of unsmooth glue discharging under the condition that the outer diameter of the glue filling needle ≤ 0.6 and the inner diameter ≥ 0.5 due to the reduction of the lamp bead row pitch in outdoor small-pitch products is solved.
