Problems solved by technology

[0003] The dispensing principle of the existing dispensing machine is generally to apply pressure from the back of the rubber cylinder through air pressure or mechanical pressure, so that the glue in the rubber cylinder is extruded from the slender needle tube to achieve dispensing. When linear dispensing is required When the dispensing head is needed to move on the surface of the workpiece, and at the same time to continuously extrude the glue, this method needs to consider the uniformity of the glue extrusion, so it needs continuous pressure to squeeze the glue, and the dispensing head cannot move too fast , resulting in long dispensing time and insufficient efficiency, especially in the various workpieces that require dispensing, there are many ring parts, and the dispensing of general ring parts needs to distribute glue evenly along the surface of the ring, for this Dispensing tools specially designed for dispensing of such workpieces have a strong market demand and can bring significant benefits, which can improve the above problems and improve the dispensing efficiency of circular workpieces; however, linear dispensing is easy due to the large amount of dispensing. In the case of glue dripping, this technical problem will be one of the important problems to be overcome in the development of the linear dispensing industry

Embodiment 1

[0038] see Figures 1 to 3 And 5, a dispensing tray for annular glue discharge, including an annular glue needle 1 and a glue cartridge 2; the glue cartridge 2 is arranged in the middle of the glue dispensing tray, and passes through an annular glue channel 3 as a glue needle under external pressure 1 to supply glue, so that the glue liquid is extruded from the bottom of the glue needle 1; the vertical section of the glue channel 3 is a lying S-shaped curved channel.

[0039]Use the glue channel design of the S-shaped curved channel with the vertical section to reduce or avoid the occurrence of glue dripping. The principle is that when the glue dispensing is completed and the glue is stopped, the glue in the glue needle 1 will move down under gravity. A small distance, the distance can make the glue partially protrude from the glue outlet of the glue needle 1, but not enough to make it big and drip; The inner bend of the rubber needle is kept full of glue, and the filled glue...

Embodiment 2

[0050] see Figure 4 and 5 , a ring-shaped dispensing disc for dispensing glue, including an annular glue needle 1 and a rubber cylinder 2; Glue, so that the glue liquid is extruded from the bottom of the glue needle 1; the vertical section of the glue channel 3 is a flat S-shaped curved channel.

[0051] Further, the glue needle 1 and the glue channel 3 are surrounded by the upper elastic sheet 41 and the lower elastic sheet 42; the upper elastic sheet 41 and the lower elastic sheet 42 are connected by a plurality of pieces evenly distributed around the center of the dispensing disc The sheet 43 is fixedly connected.

[0052] Further, the thickness of the upper elastic sheet 41 and the lower elastic sheet 42 and / or the connecting sheet 41 gradually decreases from the center of the dispensing tray outward.

[0053] Further, a serrated elastic disc 51 is arranged under the lower elastic sheet 42 and is sealed and fixedly connected with the inner and outer walls of the rubber...

Abstract

The invention relates to a dispensing disc achieving environment-friendly glue discharging. The dispensing disc comprises an annular glue needle and a glue barrel. The glue barrel is arranged in the middle of the dispensing disc, glue is supplied to the glue needle through an annular glue channel under external pressure, and the glue is extruded out from the bottom end of the glue needle. The vertical section of the glue channel is a flatly-laid S-shaped bent channel. The dispensing disc can achieve annular linear glue discharging, for an annular workpiece, the dispensing speed is greatly increased, meanwhile, by means of the design, the situation of glue dripping can be reduced or avoided, and actual production requirements are met.

Description

technical field [0001] The invention relates to the field of dispensing machines, in particular to a dispensing tray for circular glue discharge. Background technique [0002] Glue dispensing machine, also known as glue applicator, glue dispenser, glue machine, glue pouring machine, etc., specializes in controlling fluid. And the automatic machine that drips and coats the fluid on the surface of the product or inside the product can realize three-dimensional and four-dimensional path dispensing, precise positioning, precise glue control, no wire drawing, no glue leakage, and no glue dripping. The glue dispenser is mainly used for accurate pointing, injecting, coating, and dripping of glue, paint and other liquids in the product process to the precise position of each product, and can be used to achieve dots, lines, circles or arcs. [0003] The dispensing principle of the existing dispensing machine is generally to apply pressure from the back of the rubber cylinder through...
