Description

Technical Field

[0001] The utility model relates to the field of glue drawing machines, in particular to a multi-purpose double-valve glue drawing machine. Background Art

[0002] The light strip glue drawing machine is an automated device for drawing glue and encapsulating chips on the LED light strip substrate. The existing light strip glue drawing machine includes a frame, a conveyor belt arranged on the frame, and a glue drawing valve arranged on one side of the conveyor belt. The existing light strip glue drawing machine uses a single glue drawing valve to draw glue and encapsulate on the light strip substrate at one time, and the glue output is large. However, since the glue has a certain fluidity, when a large amount of glue is output at one time, the surface of the glue strip will be uneven (wavy) due to the slight flow of glue, and the surface flatness is poor, which affects the light output effect.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example: Figure 1-6 As shown, the multi-purpose double-valve glue drawing machine includes a frame 1, a conveyor belt 2 arranged on the frame 1 and a glue drawing mechanism 3 arranged on one side of the conveyor belt 2. The glue drawing mechanism 3 includes two glue drawing heads 301 located above the conveyor belt 2 and spaced apart in the conveying direction of the conveyor belt 2. The two glue drawing heads 301 draw glue independently. Independent glue drawing means that both glue drawing heads 301 can draw glue and the two glue drawing are independent of each other and do not affect each other. The two glue drawing heads 301 have glue outlet holes 302 for discharging glue. The line connecting the centers of the two glue outlet holes 302 is parallel to the conveying direction of the conveyor belt 2. A control box (not shown in the figure) is provided on the frame 1, and the conveyor belt 2 and the glue drawing mechanism 3 are controlled by the control box.

[0026] When the multi-purpose double-valve glue drawing machine is used to draw glue and encapsulate the chips on the LED light strip substrate, the steps are as follows: first, the light strip substrate is placed on the conveyor belt 2, and the length direction of the light strip substrate is parallel to the conveying direction of the conveyor belt 2, then, a glue drawing head 301 draws glue on the light strip substrate, and finally, another glue drawing head 301 continues to draw glue on the glue strip formed by the previous glue drawing head 301. Among them, the thickness of the glue strip formed by one glue drawing head 301 on the light strip substrate is defined as H1, and the thickness of the glue strip formed by another glue drawing head 301 on the glue strip formed by the previous glue drawing head 301 is defined as H2, and the sum of the thicknesses of H1 and H2 is equal to the thickness of the glue strip that needs to be covered on the light strip substrate.

[0027] The colors of the adhesive strips formed by the two adhesive pulling heads 301 can be the same or different, and the materials can be the same or different, which is specifically determined by the material and color of the material injected into the adhesive pulling heads 301 .

[0028] In summary, the present embodiment provides a multi-purpose double-valve glue drawing machine to solve the problem that the existing light strip glue drawing machine has a single-valve glue drawing, and the glue output is large, resulting in poor surface flatness of the glue strip encapsulated on the chip, which affects the light output effect. The two glue drawing heads 301 are mainly arranged in the conveying direction of the conveyor belt 2, and the center line of the glue outlet holes 302 of the two glue drawing heads 301 is parallel to the conveying direction of the conveyor belt 2, so that the two glue drawing heads 301 can draw glue on the light strip substrate in batches and stack to form a glue strip of preset thickness. Since the glue strip covered on the light strip substrate is formed by the two glue drawing heads 301 drawing glue in batches and stacking, the glue output of each glue drawing head 301 is less than the total amount of the required thickness of the glue strip, so the single glue output is effectively reduced (the fluidity of the glue is proportional to the glue output, and its fluidity is very small when the glue output is small), avoiding the formation of wavy texture on the surface of the glue strip due to the large single glue output, making the surface of the glue strip flat and having a good light output effect.

[0029] The glue output ratio of the two glue heads 301 includes but is not limited to 1:9, 2:8, 3:7, 4:6, and 5:5.

The line connecting the centers of the front glue outlet hole 302 and the rear glue outlet hole 302 is parallel to the conveying direction of the conveyor belt 2. There are a plurality of front glue holes 303, and the plurality of front glue holes 303 are arranged at intervals in the left-right direction. There are a plurality of rear glue holes 304 and they correspond to the plurality of front glue holes 303 one by one. The line connecting the centers of the rear glue holes 304 and the corresponding front glue holes 303 is parallel to the conveying direction of the conveyor belt 2. The above arrangement improves the glue pulling efficiency of the glue pulling machine by configuring the glue outlet holes 302 into a plurality of holes.

Specifically, the fastener is a bolt. The above-mentioned arrangement is achieved by configuring a plurality of mounting holes 307 spaced apart on the mounting seat 305, configuring long holes 308 matching the plurality of mounting holes 307 on the connecting seat 306, and fasteners penetrating from the long holes 308 into the mounting holes 307 to lock the connecting seat 306 on the mounting seat 305, so that the rubber pulling head 301 can move left and right along the mounting seat 305 and the rubber pulling head 301 can be locked on the mounting seat 305 after the rubber pulling head 301 moves into place. The structure is simple and easy to implement.

[0033] In the embodiment of the utility model, a precision adjuster 300 is provided on the mounting seat 305 to drive the connecting seat 306 to move along the mounting seat 305 .

[0034] In the embodiment of the utility model, one of the connecting seat 306 and the mounting seat 305 is provided with a guide rail 310 extending left and right, and the other is provided with a slider 311 slidably matched with the guide rail 310.
