Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing equipment, in particular to a servo glue pushing device used for precise glue dispensing. Background Art

[0002] The servo glue pusher is a device used to precisely control the spraying, pushing or coating of liquid glue or adhesive. It usually consists of a liquid glue supply system, a servo drive system and a control system. The servo glue pusher is widely used in the electronics, automobile, medical equipment, furniture and other industries in automated production for glue coating, sealing, bonding and other processes. It can improve production efficiency, product quality and consistency, and reduce production costs, so it has been widely welcomed and applied. When dispensing glue on workpieces in all fields, it is necessary to perform precise dispensing to ensure the stability of the workpiece. Precision dispensing is a technology commonly used in industrial production to precisely control the dispensing of liquid glue. It uses specially designed equipment to apply glue or adhesive in tiny dots or lines at specific locations on the product.

[0003] After searching: Chinese patent announcement number: CN218394459U, it relates to the technical field of dispensing equipment, and discloses a small servo glue pushing device used for precision dispensing, which includes a base plate, a servo motor, a clamping mechanism and a double-liquid back-sucking valve, the servo motor and the clamping mechanism are both arranged at the front of the base plate, and the clamping mechanism is located above the servo motor, and the double-liquid back-sucking valve is installed at the front end of the clamping mechanism through a flow channel assembly; the rear end of the servo motor is connected to a screw rod, and a support seat is slidably arranged at the rear position of the base plate, and the support seat is assembled on the screw rod through a screw nut, and a piston rod is arranged at the front side of the support seat, and the piston rod is slidably connected to the clamping mechanism and a piston is arranged at the front end of the piston rod; the clamping mechanism is used to clamp and fix the packaging rubber cylinder, and the servo motor controls the rotation of the screw rod to drive the support seat to move forward and then drive the piston rod to push the glue forward. The utility model folds the screw rod and the piston rod, and adopts a folding servo glue pushing structure, which compresses the overall occupied space and reduces the quality of the device.

[0004] The above patent specification states in the embodiment that "in order to facilitate timely replacement of the glue barrel, a low liquid level sensor 14 is provided on the reinforcing rib 11 of the present embodiment, and a low liquid level detection plate 15 corresponding to the low liquid level sensor 14 is installed at the front end of the support seat 4. The low liquid level sensor 14 can use an existing slot-type photoelectric sensor. When the low liquid level detection plate 15 enters the slot of the low liquid level sensor 14, it reminds and displays the low liquid level, and then the new glue can be replaced in time according to demand." This can detect the internal capacity of the glue barrel and replace it in time. However, when the capacity is insufficient, the workpiece being glued will continue to be glued after the glue barrel is replaced, and the quality of the workpiece glue dispensing cannot be guaranteed. Therefore, in view of the above-mentioned deficiencies, a new servo glue pushing device for precision glue dispensing is proposed. Utility Model Content
