Description

Technical Field

[0001] This utility model relates to the field of glue supply systems, and more particularly to a glue application pump. Background Technology

[0002] During automobile assembly, adhesive needs to be applied to the windshield to facilitate its installation. In the entire production process, a central adhesive supply system is typically used to supply adhesive to the appropriate locations on each production line. A typical central adhesive supply system has an adhesive pump for pumping the adhesive. However, the limited pumping distance of the adhesive pump in related technologies leads to low production efficiency. Furthermore, the adhesive pump often needs to reciprocate during production, requiring frequent reversing of direction, resulting in a high failure rate of the commutator, which further impacts production efficiency.

[0019] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0020] Reference Figure 1-3 A glue dispensing pump includes a mounting frame, a glue tank placed below the pump, and the pump extending into the tank. The pump includes a pumping assembly and a lifting assembly. The lifting assembly is mounted on the mounting frame and connected to the pumping assembly, which drives it to move towards the bottom of the glue tank. This design ensures that as the pumping assembly descends, it maintains close contact with the glue inside the tank, minimizing air bubbles and improving dispensing efficiency.

[0021] In this embodiment, the lifting assembly includes a driving unit and a positioning unit. The positioning unit is mounted on the mounting frame and extends along the depth direction of the glue bucket. The driving unit is mounted on the mounting frame and positioned above the glue bucket. The pumping assembly is connected to the driving unit and is driven by the driving unit to reciprocate within the glue bucket. The driving unit includes at least one pair of lifting cylinders, which are fixed on the mounting frame. The drive shaft of the lifting cylinder is fixed to the pumping unit, and the lifting cylinder drives the pumping unit to extend into the glue bucket. The positioning unit includes a limit switch, an outer sleeve, and an inner sleeve. The outer sleeve and the inner sleeve are nested together and located on one side of the glue bucket along its depth direction. One end of the outer sleeve is fixed to the bottom of the mounting frame, and one end of the inner sleeve is fixed to the pumping unit. When the pumping unit reciprocates, the inner sleeve extends and retracts within the outer sleeve. During pumping, the position of the limit switch is adjusted to limit the stroke of the lifting cylinder. The lifting cylinder drives the entire pumping assembly to contact the glue in the glue bucket for pumping. As the pumping process unfolds, the lifting cylinder lowers the pump assembly until it contacts the bottom of the glue container. When the glue container needs to be replaced, the lifting cylinder rises to its maximum stroke, removing the pump assembly from the container for easy replacement.

[0022] In this embodiment, the adhesive pumping assembly includes an adhesive gathering section and a pumping section. The pumping section is connected to the adhesive gathering section and has an adhesive outlet. The adhesive outlet is connected to the outside via a pipe. The pumping section reciprocates and pumps adhesive from the adhesive gathering section to the adhesive outlet. The pumping section includes a mounting beam, a suction tube, and a drive motor. The mounting beam is mounted on the drive shaft of a pair of lifting cylinders. The drive motor is mounted on the mounting beam and positioned directly above the adhesive tank. One end of the suction tube is connected to the drive motor, and the other end extends into the adhesive tank and communicates with the adhesive gathering section inside the tank. The adhesive outlet is located on the outer wall of the suction tube and communicates with it. The suction tube includes a pull rod and a delivery pipe. One end of the delivery pipe is fixed to the mounting beam, and the other end is inserted into the adhesive tank and communicates with the adhesive gathering section. The pull rod is located on the inner wall of the delivery pipe and has a delivery protrusion. When the pull rod moves, the delivery protrusion is inside the delivery pipe. The glue-forming section includes a glue-forming ring with a glue inlet hole in its center. A glue delivery pipe connects to the glue delivery pipe through this inlet hole. One end of the glue delivery pipe connected to the inlet hole has an enlarged hole. One end of a pull rod extends into this enlarged hole and is equipped with a valve plate. When the pull rod moves upward, the valve plate abuts against the bottom of the enlarged hole. During use, the glue-forming ring needs to be in contact with the inner wall of the glue tank to prevent glue from overflowing above the ring when the pump assembly moves downward, thus affecting the pumping effect. During pumping, the pull rod reciprocates. When the pull rod moves downward, the valve plate moves downward, and the glue delivery protrusion moves within the glue delivery pipe, which is filled with glue. When the glue delivery protrusion moves downward, it squeezes the glue, which is then pumped out from the outlet. When the pull rod moves downward, the adhesive enters the expansion hole through the outlet. When the adhesive feeding protrusion moves upward, the adhesive is still pumped out through the outlet. That is, no matter how the pull rod moves, the adhesive can be pumped and the amount of adhesive pumped is determined by the volume of the adhesive feeding protrusion, thus achieving continuous and uniform adhesive pumping.

[0023] Compared to existing technologies, this invention uses a linear drive device such as a cylinder as the drive motor, avoiding the use of a reversing device and eliminating the vulnerability of the reversing device. Furthermore, the drive motor and the drive unit work together to achieve greater pressure and a longer pumping distance during glue delivery. The limit switch is adjustable in position on the outer sleeve, accommodating glue buckets of varying depths and broadening its applicability.

[0024] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
