Description

Technical Field

[0001] The invention relates to a side coating needle head, which is mainly suitable for the electronics industry, lighting industry, automobile industry, industrial electrical industry, etc. Background Art

[0002] The traditional application of the present invention is manual coating, for example, coating the inside of a groove with a depth of 50 mm and a width of 8 mm with glue, and manually using a small plate to coat the inside of the groove, the thickness is uneven and the amount of glue coated is also unstable. Therefore, we propose a side coating needle. Summary of the invention

[0003] The utility model aims to provide a side coating needle head, which solves the problems in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following scheme: a side coating needle, comprising an external thread, a hexagonal nut, a flow channel, a flow channel plate, and a glue coating port, wherein the external thread is at the upper end of the hexagonal nut, the lower end of the hexagonal nut is the flow channel plate, the flow channel plate contains a flow channel inside, and the glue coating port is on both sides of the flow channel plate.

[0005] Preferably, the external thread is a standard G1 / 4 thread, which can be quickly installed on the rubber valve.

[0006] Preferably, the external thread, the hexagonal cap, the flow channel, the flow channel plate and the glue coating port are integrally formed.

[0007] Compared with the existing technology, the beneficial effect of the utility model is that the side coating needle allows the glue to be coated on the inner side of the groove through the side opening of the flow channel plate, thereby achieving a stable coating amount and uniform thickness. BRIEF DESCRIPTION OF THE DRAWINGS

[0008] Figure 1 It is a schematic diagram of the structure of the utility model.

[0009] In the figure: 1 external thread, 2 hexagonal cap, 3 flow channel, 4 flow channel plate, 5 glue coating port. DETAILED DESCRIPTION

[0010] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0011] With reference to FIG1 , the present invention provides a side coating needle head, which mainly comprises an external thread (1), a hexagonal cap (2), a flow channel (3), a flow channel plate (4), and a glue coating port (5).

[0012] By customizing flow channel plates (4) of different lengths and corresponding glue application ports (5), coating of grooves of different depths can be achieved. For example, when the depth of the groove of the workpiece is 50 mm, two 2 mm wide glue lines need to be applied on the inner side of the groove. This can be achieved by customizing a 60 mm flow channel plate (4) and opening a rectangular glue application port (5) with a width of 2 mm and a length of 50 mm on the side of the flow channel plate. After assembly, a glue line with a length of 50 mm and a width of 2 mm can be spit out. The side coating needle can achieve coating of grooves of different depths, thereby achieving more efficient dispensing.

[0013] Working principle: When in use, when glue is dispensed through this side coating needle, it is connected to the syringe through the external thread (1), and the glue in the syringe enters the flow channel (2). Then, the side coating needle (different widths can be customized) is spaced from the workpiece at different distances (for example, 0.5mm, the distance between the side and the workpiece is the coating thickness), so as to achieve dispensing of different depths.
