Description

Technical Field

[0001] The utility model relates to the field of LED display module production, in particular to a glue filling device for an LED display module. Background Art

[0002] The existing glue injection device for LED display modules generally has a plurality of glue injection needles arranged side by side, each of which is arranged at equal intervals and has a hole diameter of 1.3 mm. However, since some LED display modules are provided with a rocker hole, such LED display modules with a rocker hole are maintained by front maintenance; and when such LED display modules with a rocker hole are injected with glue using the existing glue injection needle, the sealing glue will leak out of the rocker hole, affecting the production of the LED display module.

[0003] In view of the above problems, it is necessary to study a glue potting device for an LED display module, which can effectively prevent the potting glue from leaking from the rocker hole of the LED display module. Utility Model Content

[0004] The utility model aims to provide a glue potting device for an LED display module, which can effectively prevent the potting glue from leaking from the rocker hole of the LED display module.

[0005] In order to achieve the above purpose, the solution of the utility model is:

[0006] A glue filling device for an LED display module comprises a needle head seat and a plurality of glue filling needles which cooperate with the bottom of the needle head seat and are arranged side by side, wherein the glue filling needles are arranged at equal intervals; the glue filling needles corresponding to the rocker arm holes of the LED display module are blocked, and the apertures of the two glue filling needles adjacent to the glue filling needles corresponding to the rocker arm holes are greater than 1.3 mm.

[0007] The apertures of the two glue injection needles adjacent to the glue injection needle corresponding to the rocker arm hole are 1.4 mm.

[0008] The apertures of the two glue filling needles at the outermost edges of each glue filling needle are larger than 1.3 mm.

[0009] The apertures of the two glue filling needles at the outermost edges of each glue filling needle are 1.4 mm.

[0010] The apertures of all the glue filling needles except the two glue filling needles at the outermost edges and the two glue filling needles adjacent to the glue filling needle corresponding to the rocker arm hole are 1.3 mm.

[0011] The apertures of the various glue injection needles are all set to be the same, that is, the aperture of each glue injection needle is 1.8 mm, and the intervals between adjacent glue injection needles are 5 mm.

[0012] The bottoms of all the glue filling needles except the glue filling needle corresponding to the rocker arm hole and the two glue filling needles at the outermost edges are arranged flush.

[0013] Each glue filling needle is divided into a first glue filling needle and a second glue filling needle longer than the first glue filling needle. Each first glue filling needle and the second glue filling needle are arranged crosswise and at intervals. Each first glue filling needle is blocked, and the glue filling needle corresponding to the rocker arm hole belongs to the first glue filling needle.

[0014] After adopting the above scheme, when the glue filling device of an LED display module of the utility model fills the LED display module with glue, since the glue filling needle corresponding to the rocker arm hole is blocked, the glue filling needle corresponding to the rocker arm hole will not output the potting glue, and at the same time, the aperture of the two glue filling needles adjacent to the glue filling needle corresponding to the rocker arm hole is greater than 1.3mm, so that the potting glue output by the two glue filling needles adjacent to the glue filling needle corresponding to the rocker arm hole can flow to the area where the rocker arm hole of the LED display module is located, ensuring that the LED display module can be completely covered by the potting glue. Among them, the utility model is to use the potting glue output by two glue filling needles adjacent to the glue filling needle corresponding to the rocker arm hole to flow to the area where the rocker arm hole of the LED display module is located to fill the area where the rocker arm hole of the LED display module is located, and the potting glue output by two glue filling needles adjacent to the glue filling needle corresponding to the rocker arm hole has a slower flow rate in the area where the rocker arm hole of the LED display module is located, so that the potting glue is basically solidified when it flows to the rocker arm hole of the LED display module, thereby effectively preventing the potting glue from leaking from the rocker arm hole of the LED display module.

[0022] like Figures 1 to 5As shown, the utility model discloses a glue filling device for an LED display module, which includes a needle head seat 1 and a plurality of glue filling needles 2 that are matched with the bottom of the needle head seat 1 and arranged side by side, and the glue filling needles 2 are arranged at equal intervals; the glue filling needles 2 corresponding to the rocker arm holes of the LED display module among the glue filling needles 2 are blocked, and the apertures of the two glue filling needles 2 adjacent to the glue filling needles 2 corresponding to the rocker arm holes are greater than 1.3 mm.

[0023] When a glue filling device of an LED display module of the utility model fills the LED display module with glue, since the glue filling needle 2 corresponding to the rocker arm hole is blocked, the glue filling needle 2 corresponding to the rocker arm hole will not output the potting glue, and at the same time, the aperture of the two glue filling needles 2 adjacent to the glue filling needle 2 corresponding to the rocker arm hole is greater than 1.3 mm, so that the potting glue output by the two glue filling needles 2 adjacent to the glue filling needle 2 corresponding to the rocker arm hole can flow to the area where the rocker arm hole of the LED display module is located, ensuring that the LED display module can be completely covered by the potting glue. Among them, the utility model is to flow the potting glue output by two potting needles 2 adjacent to the potting needles 2 corresponding to the rocker arm holes to the area where the rocker arm holes of the LED display module are located to pot the area where the rocker arm holes of the LED display module are located, and the potting glue output by two potting needles 2 adjacent to the potting needles 2 corresponding to the rocker arm holes has a slower flow rate in the area where the rocker arm holes of the LED display module are located, so that the potting glue is basically solidified when it flows to the rocker arm holes of the LED display module, thereby effectively preventing the potting glue from leaking from the rocker arm holes of the LED display module.

[0024] In order to further explain the technical solution of the present utility model, the present utility model is described in detail below through specific embodiments. Embodiment 1

[0025] Cooperate Figure 1 As shown, in embodiment 1 of the present utility model, the aperture of the two glue filling needles 2 adjacent to the glue filling needle 2 corresponding to the rocker arm hole is 1.4 mm, so as to ensure that the potting glue output by the two glue filling needles 2 adjacent to the glue filling needle 2 corresponding to the rocker arm hole can flow to the area where the rocker arm hole of the LED display module is located, and the flow rate of the potting glue output by the two glue filling needles 2 adjacent to the glue filling needle 2 corresponding to the rocker arm hole in the area where the rocker arm hole of the LED display module is located is slow.

[0026] In the first embodiment of the present invention, the apertures of the two glue injection needles 2 at the edge of each glue injection needle 2 are greater than 1.3 mm, so that the potting glue can flow to the edge of the LED display module, ensuring that the edge of the LED display module is covered by the potting glue. Specifically, the apertures of the two glue injection needles 2 at the edge of each glue injection needle 2 are 1.4 mm.

[0027] In embodiment 1 of the present utility model, the aperture of all the glue filling needles 2 except the two glue filling needles 2 at the edge and the two glue filling needles 2 adjacent to the glue filling needle 2 corresponding to the rocker arm hole can be 1.3 mm, and the glue filling needle 2 corresponding to the rocker arm hole can be sealed by locking with screws 3. Embodiment 2

[0028] Cooperate Figure 2 As shown, in the second embodiment of the present invention, the apertures of the glue injection needles 2 are all set to be the same; specifically, the aperture of each glue injection needle 2 is 1.8 mm, so that the glue discharging rate of the glue injection needle 2 is fast, and adjacent glue injection needles 2 are set at an interval of 5 mm.

[0029] Cooperate Figure 2 As shown, in the second embodiment of the present utility model, each glue filling needle 2 is divided into a first glue filling needle 201 and a second glue filling needle 202 which is longer than the first glue filling needle 201.

The glue filling needle 2 corresponding to the rocker arm hole belongs to the first glue filling needle 201. The two glue filling needles 2 at the outermost edges of each glue filling needle 2 belong to the second glue filling needle 202. Each first glue filling needle 201 can be blocked by locking with a screw 3.

[0030] Among them, since the first glue filling needle 201 is blocked, the glue filling device of an LED display module of the utility model can discharge glue at intervals of 10mm, and ensure that the potting glue output by the two glue filling needles 2 adjacent to the glue filling needle 2 corresponding to the rocker arm hole can flow to the area where the rocker arm hole of the LED display module is located, and the flow rate of the potting glue output by the two glue filling needles 2 adjacent to the glue filling needle 2 corresponding to the rocker arm hole in the area where the rocker arm hole of the LED display module is located is slow.

[0031] It should be noted that the glue-filling device for an LED display module in the second embodiment is suitable for an LED display module with a lamp bead spacing of 5 mm (ie, an LED display module of model Q5). Embodiment 3

[0032] Cooperate Figure 3As shown, in Example 3 of the present invention, the apertures of each glue filling needle 2 are set to be the same; specifically, the aperture of each glue filling needle 2 is 1.8mm, so that the glue discharge rate of the glue filling needle 2 is fast, and adjacent glue filling needles 2 are set at an interval of 5mm, and the bottoms of all glue filling needles 2 except the glue filling needle 2 corresponding to the rocker arm hole and the two glue filling needles 2 at the edge are set flush; the present invention is set in this way, so that the glue filling device of an LED display module of the present invention can discharge glue at an interval of 5mm, and the overall glue discharge rate of the glue filling device of an LED display module of the present invention is fast, which effectively improves the production efficiency; and it can also ensure that the potting glue output by the two glue filling needles 2 adjacent to the glue filling needle 2 corresponding to the rocker arm hole can flow to the area where the rocker arm hole of the LED display module is located, and the flow rate of the potting glue output by the two glue filling needles 2 adjacent to the glue filling needle 2 corresponding to the rocker arm hole in the area where the rocker arm hole of the LED display module is located is slow. Embodiment 4

[0033] Cooperate Figure 4 As shown, in the fourth embodiment of the present invention, the apertures of the glue injection needles 2 are all set to be the same; specifically, the aperture of each glue injection needle 2 is 1.8 mm, so that the glue discharging rate of the glue injection needle 2 is fast, and adjacent glue injection needles 2 are set at an interval of 5 mm.

Among them, since the first glue injection needle 201 is blocked, the glue injection device of the LED display module of the present utility model can discharge glue at intervals of 10mm, and ensure that the two glue injection needles 2 adjacent to the glue injection needle 2 corresponding to the rocker hole can flow to the area where the rocker hole of the LED display module is located, and the flow rate of the two glue injection needles 2 adjacent to the glue injection needle 2 corresponding to the rocker hole is slow in the area where the rocker hole of the LED display module is located.

[0035] It should be noted that the glue pouring device of an LED display module in the fourth embodiment is suitable for an LED display module with a lamp bead spacing of 10 mm (i.e., an LED display module of model Q10). The glue pouring device of an LED display module in the fourth embodiment and the glue pouring device of an LED display module in the second embodiment can actually use the same glue pouring device, and by correspondingly defining and blocking each glue pouring needle 2 of the glue pouring device, the glue pouring device of an LED display module in the fourth embodiment and the glue pouring device of an LED display module in the second embodiment can be obtained accordingly.
