Description

Technical Field

[0001] The utility model relates to the technical field of glue coating equipment, in particular to a glue coating system metering system. Background Art

[0002] Glue coating machine is also called glue dripping machine, glue spraying machine, glue filling machine, etc. It is a special machine for controlling fluids. It is an automated machine that drips and applies fluids on the surface or inside of products. It can achieve three-dimensional and four-dimensional path dispensing, precise positioning, precise glue control, no drawing, no glue leakage, and no glue dripping. Dispensing machines are mainly used for the precise dotting, injection, coating, and dripping of glue, paint and other liquids in product processes to the precise position of each product. It can be used to achieve dotting, drawing lines, circles or arcs.

[0003] Among them, the utility model with the authorization announcement number CN209093738U discloses a glue coating system, which can turn off the second heater through the controller to ensure that the temperature in the insulation box is at the set temperature. The controller can control the wind force of the fan. The setting of the fan can increase the circulation of air in the insulation box, so that the glue in the insulation box can be heated more evenly, thereby enhancing the initial adhesion, sustained adhesion, peeling force and other viscosity of the glue, thereby reducing the work intensity of workers, ensuring that the material and the glue will not be wrinkled, bent, or offset when they are attached, and improving production efficiency. However, it only controls the discharge of glue through the set flow valve, but it is not possible to know the amount of glue discharged well. Some glues have a high cost, so the amount of glue discharged must be controlled, so the glue needs to be metered. Utility Model Content

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-5 A gluing system metering system includes a mounting frame 1, a servo electric cylinder 4 is mounted on the top of the mounting frame 1, and a glue dispensing syringe 2 is clamped on the front surface of the mounting frame 1;

[0023] The top outer wall of the glue dispensing syringe 2 is symmetrically provided with protrusions 21 on both sides, the glue dispensing syringe 2 is connected to the glue discharge port at the bottom of the cylinder body with a glue delivery pipe 3, the surface of one side of the outer wall of the cylinder body of the glue dispensing syringe 2 is provided with a metering scale line 23, and a piston 22 is provided in the cavity of the glue dispensing syringe 2.

[0024] The mounting frame 1 includes a lower mounting plate 11 at the bottom, and mounting holes are provided on the lower mounting plate 11. The lower mounting plate 11 facilitates the installation of the entire device on the glue coating device.

[0025] In addition, an upper mounting plate 12 is provided at the upper end of the mounting frame 1 , an opening 122 is provided on the front side of the upper mounting plate 12 , and arc grooves 121 are provided on the side walls of the upper mounting plate 12 located on both sides of the opening 122 , which facilitate the removal of the limiting plug 5 .

[0026] Moreover, a pair of limiting plates 13 are symmetrically fixedly connected to the front surface of the mounting frame 1 , and a limiting rod 5 is inserted into the limiting plate 13 on each side, and the limiting rod 5 can pass through the through hole set on the limiting plate 13 .

[0027] In addition, through holes are provided on the limiting plates 13 , and a glue dispensing syringe 2 is clamped in the gap between the limiting plates 13 on each side, and a rubber pad 131 is provided on the surface of one side of the limiting plate 13 . The rubber pad 131 has a certain friction force and can clamp the glue dispensing syringe 2 .

[0028] Moreover, the protrusion 21 of the glue dispensing syringe 2 is clamped between the upper and lower limiting plates 13, and a through hole is opened on the protrusion 21 for the limiting rod 5 to pass through. The protrusion 21 is used to be clamped on the limiting plates 13 on both sides, so as to install the glue dispensing syringe 2 on the mounting frame 1.

[0029] In addition, a piston rod 41 is provided at the bottom output end of the servo electric cylinder 4. The piston rod 41 can move into the cavity of the glue discharge syringe 2 below. The bottom end of the piston rod 41 is in contact with the upper surface of the piston 22. The piston rod 41 can push the piston 22. Unlike the air pump, the servo electric cylinder 4 is controlled by PLC. The servo electric cylinder 4 can be positioned more accurately and provide fast real-time feedback, thereby ensuring the amount of glue discharged.

[0030] In this embodiment, a mounting frame 1 is installed on the gluing system. When gluing work is required, the glue dispensing syringe 2 filled with glue is first installed on the limit plate 13. The protrusions 21 on both sides are first clamped between the limit plates 13, and it is ensured that the through holes of the protrusions 21 on both sides can be aligned with the through holes of the limit plates 13 on both sides. Then the limit plug 5 is inserted, and the limit plug 5 is passed through the limit plates 13 and the protrusions 21 to ensure that the glue dispensing syringe 2 can be firmly clamped on the limit plates 13 and will not move easily.

[0031] At this time, the internal glue content can be observed through the transparent glue discharging syringe 2, and the glue outlet at the bottom of the glue discharging syringe 2 is connected to a glue delivery tube 3, and the other end of the glue delivery tube 3 is connected to the glue coating head on the glue coating system. When delivering glue to the glue coating head, the piston rod 41 is pushed downward by the servo electric cylinder 4 to resist the piston 22, and push the piston 22 to squeeze out the glue, and the operator can know the amount of glue discharged through the measuring scale line 23, thereby controlling the amount of glue discharged, because the servo electric cylinder 4 can provide more precise positioning and fast real-time feedback, so that the piston rod 41 can be stopped from being pushed out immediately to control the amount of glue discharged.

[0032] In the utility model, the discharge of glue in the glue dispensing syringe 2 can be controlled by pushing the piston rod 41 through the servo electric cylinder 4, and the metering scale line 23 can be used to know the amount of glue discharged, and the depth of the piston rod 41 can be known through the servo electric cylinder 4, thereby playing a role in measuring the discharge of glue, so that the amount of glue delivered to the glue coating system can be well controlled, thereby not causing waste of glue.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
