Description

Technical Field

[0001] The utility model relates to the technical field of glue dispensing, in particular to a glue dispensing device for a pressure sensor. Background Art

[0002] A pressure sensor is a device or apparatus that can sense pressure signals and convert them into usable output electrical signals according to certain rules. It is usually composed of a pressure sensitive element and a signal processing unit. During the production and processing of pressure sensors, the connections of the electronic components inside them need to be reinforced and protected. Since the electronic components in pressure sensors are small in size, they need to be fixed by gluing to improve the reliability and stability of the electronic components.

[0003] When the glue dispensing device is performing glue dispensing operation on electronic components, glue can flow from the glue storage cylinder to the glue dispensing head and drip out from the glue dispensing head, but a small amount of glue will remain inside the glue dispensing head. If it is not cleaned in time, it will easily cause blockage inside the glue dispensing head, affecting the glue dispensing effect. The existing glue dispensing device does not have a facility for cleaning the glue dispensing head, and cannot quickly and effectively remove the glue inside the glue dispensing head. The operation is relatively cumbersome and inconvenient. In view of this, the utility model proposes a pressure sensor dispensing device. Utility Model Content

The cleaning mechanism includes a fixed rod 10 and a movable plate 11, and a cleaning needle 12 arranged on the top of the movable plate 11. The middle section of the cleaning needle 12 is semicircular, and the inside of the glue dispensing head 7 can be cleaned by the cleaning needle 12.

[0025] Furthermore, the top end of the fixed rod 10 is fixed to the inner top wall of the transverse driving frame 2, and the bottom end of the fixed rod 10 is connected to the internal rotation of the movable plate 11. By rotating the movable plate 11, it can be taken out for use and storage. The top of the movable plate 11 is fixedly connected with a socket 13, and the bottom end of the cleaning needle 12 is movably plugged into the inside of the socket 13. The cleaning needle 12 can be positioned through the socket 13, and the cleaning needle 12 can be conveniently taken out upward for cleaning and replacement.

[0030] The use process of the utility model is as follows:

[0031] When in use, when it is necessary to clean the glue inside the glue dispensing head 7, the movable ring 18 can be moved upward through the two pull plates, and the limiting slider 23 slides inside the limiting slide groove 22. At the same time, the spring 19 contracts and drives the positioning rod 20 to move upward together, so that its bottom end can move out from the inside of the positioning hole 21, and the movable plate 11 can be rotated forward ninety degrees, and the cleaning needle 12 can be located directly below the glue dispensing head 7, and the bottom of the movable plate 11 overlaps with the top of the vacuum suction cup 9 to ensure the stability of the movable plate 11.

The spring 19 recovers and drives the movable ring 18 and the positioning rod 20 to move downward. The positioning rod 20 is plugged into the inside of the positioning hole 21, so that the movable plate 11 can be fixed to prevent it from rotating. Then, the hydraulic cylinder 5 is extended during operation, so that the glue storage tube 6 and the glue dispensing head 7 can be driven to move downward together. When the glue dispensing head 7 is sleeved with the cleaning needle 12, as the glue dispensing head 7 reciprocates up and down, the cleaning needle 12 can dredge the inside of the glue dispensing head 7 to make the glue flow out, so that the glue inside the glue dispensing head 7 can be cleaned. After cleaning, the limiting roller 16 is pulled, and the spring rod 15 contracts at the same time to move the limiting roller 16 out of the semicircular ring of the cleaning needle 12, so that the cleaning needle 12 can be moved upward and taken out from the inside of the sleeve 13 for cleaning and replacement.
