[0034] The present utility model will be further described in detail below with reference to the accompanying drawings.

[0035] As Figures 1-4 shown, the present utility model discloses an AB glue dispensing device, which is characterized by comprising:

[0036] Mounting plate 1;

[0037] A glue feeding mechanism, including a first glue feeding assembly 2 and a second glue feeding assembly 3, the first glue feeding assembly 2 is provided with a first glue feeding port 21, the second glue feeding assembly 3 is provided with a second glue feeding port 31, the first glue feeding port 21 is connected to an A glue storage barrel, and the second glue feeding port 31 is connected to a B glue storage barrel;

[0038] A glue pressing mechanism, including: a glue pressing member 4, two accommodating cavities 41 are arranged inside the glue pressing member 4, the accommodating cavities 41 are respectively connected to the first glue feeding assembly 2 and the second glue feeding assembly 3, and a piston 42 that can move up and down is arranged inside the accommodating cavity 41;

[0039] A glue dispensing mechanism, which is communicated with the glue pressing member 4, includes a glue outlet head 5, and the glue outlet head 5 is connected with a glue outlet pipe 51.

[0040] The advantage of adopting the above technical solution is that a piston 42 that can move up and down is provided. When the piston 42 moves upward, the glue enters the glue pressing member 4, and when the piston 42 moves downward, the glue is extruded into the glue outlet pipe 51. The structure is simple, suitable for high-viscosity glue, with high precision and low cost.

[0041] In some implementation schemes, the first glue feeding assembly 2 includes: a first glue block 22 and a first valve 23 arranged on the upper side of the first glue block 22, the first glue feeding port 21 is arranged on the first valve 23, a first channel 24 communicated with the first valve 23 is arranged inside the first glue block 22, the first valve 23 controls the opening and closing of the first channel 24, and the first channel 24 is communicated with the accommodating cavity 41 of the glue pressing member 4.

[0042] When injecting glue, the first valve 23 is opened, and the glue enters the receiving cavity of the glue pressing member 4 through the first channel 24. There is no need to separately set an extrusion device on the glue bucket. When discharging glue, the first valve 23 is closed, and the glue enters the glue discharging head 5 and is discharged from the glue discharging pipe 51 to realize the glue discharging operation, with a simple structure.

[0043] In some embodiments, the second glue injection assembly 3 includes: a second glue block 32 and a second valve 33 arranged on the upper side of the second glue block 32. The second glue inlet 31 is arranged on the second valve 33. A second channel 34 is arranged in the second glue block 32, and the second valve 33 controls the opening and closing of the second channel 34. The second channel 34 is connected to another receiving cavity 41 of the glue pressing member 4, so that the two receiving cavities 41 of the glue pressing member 4 respectively receive glue A and glue B. Controlled by the second valve 33, the structure is simple.

[0044] In some embodiments, the piston 42 is connected with a driving assembly, including a driving motor 6, a lead screw 61, and a moving block 62. The output end of the driving motor 6 is connected to the lead screw 61. The moving block 62 is installed on the lead screw 61 and moves up and down along the lead screw 61. Two connecting rods are arranged at the bottom of the moving block 62 and are connected to the piston 42. The connecting rods are fixed side by side on the lower side of the moving block 62 and are connected to the piston 42. By rotating the lead screw 61 to drive the moving block 62 to move up and down, the piston 42 is further driven to move to suck the glue from the glue bucket into the receiving cavity 41 or to press the glue out from the glue discharging head 5, ensuring the glue discharging accuracy and the glue discharging ratio. At the same time, the glue discharging pressure can also be increased, which is applicable to glues with different viscosities.

[0045] Furthermore, a guide rail 11 is arranged on the side of the mounting plate 1. The guide rail 11 is arranged vertically. A slider 12 is arranged on the guide rail 11, and the slider 12 is connected to the moving block 62. A position sensing device is arranged on the side of the guide rail 11, including an induction piece arranged on the side of the moving block 62 and a sensor arranged on the side of the guide rail 11. The sensors are arranged up and down. When the upper sensor senses the induction piece, the moving block 62 stops rising, and the piston 42 rises in place. Then the moving block 62 moves down until the lower sensor senses the induction piece, and the moving block 62 stops descending. At this time, the piston 42 descends in place to complete the glue discharging. The arrangement of the guide rail 11 and the slider 12 can ensure the accuracy of the moving block 62, improve the moving accuracy of the piston 42, and further improve the glue discharging accuracy.

[0046] In some embodiments, symmetric glue discharging channels 52 are arranged inside the glue discharging head 5. Glue discharging valves 53 are respectively connected to the upper sides of the glue discharging channels 52, and the glue discharging valves 53 control the opening and closing of the glue discharging channels 52. The structure of the glue discharging valves 53 is the same as that of the first valve 23 and the second valve 33, and all adopt pneumatic control, which is convenient to control and has accurate control.

[0047] The two kinds of glue coming out of the glue pressing member 4 respectively enter the corresponding glue outlet channels 52. During the upward movement of the piston 42, the glue outlet valve 53 is closed to prevent air from entering the inside of the glue pressing member 4. When the piston 42 is pressed down, the glue outlet valve 53 is opened, and the glue flows out of the glue outlet channel 52, realizing the fixed ratio of the two kinds of glue to be discharged with high precision.

[0048] In some embodiments, a spiral channel is provided in the glue outlet pipe 51, and the lower end of the glue outlet pipe 51 gradually contracts. The setting of the spiral channel mixes the AB glue, making the AB glue evenly mixed and having a good glue dispensing effect.

[0049] In some embodiments, both the first valve 23 and the second valve 33 are pneumatic valves, including: a valve body 25, a valve stem 26, and a valve plate 27. The valve plate 27 is installed at the bottom of the valve stem 26. The up and down movement of the valve stem 26 drives the movement of the valve plate 27, and the movement of the valve plate 27 realizes the on-off of the first channel 24 and the second channel 34.

[0050] The advantage of adopting the above technical solution is that the setting of the pneumatic valve is convenient to control. The on-off can be controlled by controlling the position of the valve plate 27, and the cost is low.

[0051] Further, a plurality of sealing rings are provided in the first valve 23 and the second valve 33.

[0052] The advantage of adopting the above technical solution is that the setting of a plurality of sealing rings improves the sealing performance of the whole device, prevents the leakage of the glue, and improves the glue discharging precision.

[0053] During the working process, first, the first valve 23 and the second valve 33 are opened and the glue outlet valve 53 is closed. The moving block 62 moves upward, driving the two pistons 42 to move upward. During the upward movement, suction is generated to suck the glue in the A glue bucket and the B glue bucket into the two accommodating cavities 41 respectively. Then the first valve 23 and the second valve 33 are closed, and the glue outlet valve 53 is opened. The two kinds of glue are mixed through the glue outlet pipe 51 and then discharged, completing the mixed glue discharging operation. Only two pistons 42 are provided to jointly complete the whole glue sucking and discharging actions up and down. There is no need to set up separate extrusion devices on the A glue bucket and the B glue bucket, and the glue discharging ratio is fixed at 1:1. The glue discharging amount is accurately controlled, the structure is simple, and the processing cost is reduced.

[0054] For those of ordinary skill in the art, without departing from the creative concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention.
