AI Technical Summary
In AB glue dispensing equipment, there are many types of hardeners, and there are large differences in chemical and physical properties, which leads to the fact that the glue is prone to precipitation after the equipment stops supplying glue, which takes a lot of time to stir and vacuum, reducing the efficiency of glue supply.
A AB glue dispensing equipment is designed. By setting up a B glue reflow pipeline assembly in the equipment, it ensures that when the dispensing work stops, the B glue conveying pump remains working, and the glue flows back to the B glue barrel through the B glue reflow pipeline assembly to maintain the flow state of the rubber and avoid precipitation.
By maintaining the B glue flow state, the precipitation of the rubber is avoided, and no stirring and vacuuming are required before the next dispensing work begins, which improves the glue supply efficiency and thus improves the dispensing processing efficiency.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of dispensing equipment, and particularly relates to an AB glue dispensing equipment. Background Art
[0002] AB glue is another name for two-component mixed hardening glue. One component is the base glue, and the other is the hardener. The two components need to be mixed to harden, and it does not rely on temperature for hardening and curing. Therefore, it is a kind of room-temperature hardening glue and is widely used in industrial production.
[0003] Due to the variety of hardeners and the large differences in chemical and physical properties, for some hardeners, after the supply of B glue in the equipment stops, within a certain period of time, the glue material in the glue bucket will precipitate. Therefore, before the supply of B glue is carried out again, it is necessary to stir and evacuate the glue material in the storage glue bucket, which takes a lot of time, reduces the glue supply efficiency, and thus affects the dispensing efficiency of workpieces. Content of the Utility Model
[0004] Therefore, to solve the above problems, the utility model provides an AB glue dispensing equipment.

These drawings are a part of the disclosure of the present utility model, mainly used to illustrate the embodiments and can cooperate with the relevant descriptions in the specification to explain the operating principle of the embodiments. With reference to these contents, those of ordinary skill in the art should be able to understand other possible implementation manners and the advantages of the present utility model. The components in the drawings are not drawn to scale, and similar component symbols are usually used to represent similar components.
[0021] The present utility model will be further described below in conjunction with the accompanying drawings and specific implementation manners.
[0022] Referring to Figure 1 and Figure 2 In this embodiment, an AB glue dispensing device is provided, which includes an A glue bucket (not shown in the figure), an A glue delivery pump 1, a B glue bucket 2, a B glue delivery pump 3, a dispensing device 4, an A glue pipeline assembly 5, a B glue pipeline assembly 6, and a B glue return pipeline assembly 7. The A glue delivery pump 1 is connected to the A glue bucket and is used to output the glue from the A glue bucket. The B glue delivery pump 3 is connected to the B glue bucket 2 and is used to output the glue from the B glue bucket 2. In this embodiment, the A glue delivery pump 1 adopts a pressure plate pump, and the B glue delivery pump 3 adopts a screw pump. The type of the delivery pump is selected according to the characteristics of the glue. The dispensing device 4 is used for dispensing glue to the workpiece, and it includes an A glue input end 8, a B glue input end 9, a B glue return end 10, and a dispensing end 11.
[0023] The A glue pipeline assembly 5 is connected between the A glue bucket and the A glue input end 8 of the dispensing device 4, and is used to transport the glue in the A glue bucket to the A glue input end 8 of the dispensing device 4. The B glue pipeline assembly 6 is connected between the B glue bucket 2 and the B glue input end 9 of the dispensing device 4, and is used to transport the glue in the B glue bucket 2 to the B glue input end 9 of the dispensing device 4. The B glue return pipeline assembly 7 is connected between the B glue bucket 2 and the B glue return end 10 of the dispensing device 4, and is used to transport the glue flowing out from the B glue input end 9 back into the B glue bucket 2. A commutation mechanism is provided between the B glue return end 10 and the dispensing end 11, which is used to control the flow direction of the glue flowing out from the B glue input end 9 to the dispensing end 11 or to the B glue return end 10.
[0024] When performing glue dispensing work, the A glue transfer pump 1 transfers the glue in the A glue bucket to the A glue input end 8 through the A glue pipeline assembly 5 and flows to the glue dispensing end 11; the B glue transfer pump 3 transfers the glue in the B glue bucket 2 to the B glue input end 9 through the B glue pipeline assembly 6, and the reversing mechanism in the glue dispensing device 4 controls the glue flowing out from the B glue input end 9 to flow to the glue dispensing end 11; the A glue and the B glue are mixed and then flow out from the glue dispensing end 11 to perform glue dispensing on the workpiece. When the glue dispensing work stops, the A glue transfer pump stops, the B glue transfer pump 3 keeps working, and the reversing mechanism in the glue dispensing device 4 controls the glue flowing out from the B glue input end 9 to flow to the B glue return end 10, and then is transported back to the B glue bucket 2 through the B glue return pipeline assembly 7; thus, during the period when the glue dispensing stops, the B glue remains in a flowing state, and the glue in the B glue bucket 2 will not precipitate, so there is no need to stir and evacuate again before the next glue dispensing work starts, thereby improving the glue supply efficiency and further improving the glue dispensing processing efficiency.
[0025] Specifically, the glue dispensing device 4 includes a two-component screw valve 12, and the two-component screw valve 12 is connected to the A glue input end 8, the B glue input end 9, the B glue return end 10, and the glue dispensing end 11. The reversing mechanism is arranged in the two-component screw valve 12, and the two-component screw valve 12 having a reversing function is a prior art and will not be elaborated in detail.
[0026] Furthermore, an A glue pressure reducing valve 13 is installed on the A glue pipeline assembly 5 for adjusting the pressure of the A glue flowing to the glue dispensing device 4. And an A glue pressure sensor 14 is also installed on the A glue pipeline assembly 5 for monitoring the pressure of the A glue flowing to the glue dispensing device 4. Compare the pressure display value of the A glue pressure sensor 14 with the set value, and adjust the A glue pressure reducing valve 13 to control the pressure value of the A glue.
[0027] The B glue bucket 2 is equipped with a stirring device and a vacuum pumping device. Before the initial work, the glue in the B glue bucket 2 is stirred evenly by the stirring device to avoid uneven glue discharge caused by the precipitation of the glue in the bucket. Since bubbles will inevitably be generated during the stirring process by the stirring device, the inside of the B glue bucket 2 is evacuated by the vacuum pumping device to ensure the glue discharge quality. The stirring device and the vacuum pumping device are both prior arts. One end of the B glue pipeline assembly 6 close to the B glue bucket 2 is provided with a B glue first pressure sensor 15, which can monitor the pressure of the glue flowing out from the outlet end of the B glue bucket 2. Along the glue feeding direction of the B glue pipeline assembly 6, a B glue second pressure sensor 16 is also provided on the B glue pipeline assembly 6, which can monitor the pressure of the glue about to flow to the glue dispensing device 4.
[0028] The dispensing device further includes a workbench 17, on which a driving device 18 capable of moving in the X, Y, and Z axis directions and a mounting seat 19 mounted on the driving device 18 are provided. The driving device 18 can be composed of an X-axis linear motor, a Y-axis linear motor, and a Z-axis linear motor. The dispensing device 4 is mounted on the mounting seat 19. The dispensing device further includes a control console 20, which has an integrated control module capable of controlling the operation of each component on the entire device. A vision module 21 is configured on the mounting seat 19 for collecting the position of the dispensing device 4 and feeding it back to the integrated control module. The integrated control module sends instructions to control the driving device 18 to drive the dispensing device 4 to move to the accurate position where the workpiece needs to be dispensed.
