[0001] The utility model relates to the technical field of detection devices, in particular to a detection device for a dispensing nozzle. Background Art

[0002] Glue dispensing nozzles are often used in gluing processing technology. Usually, glue is sprayed on the surface of one of the workpieces using a glue dispensing nozzle, and then the other workpiece is pressed onto the workpiece sprayed with glue to achieve gluing between the two workpieces. Existing glue dispensing nozzles are usually one-piece alloy structures with a spraying through hole in the center. Since glue dispensing nozzles are cast in production mode, burrs and rough edges are prone to appear on the inner or outer walls of newly produced glue dispensing nozzles. In the prior art, burrs and rough edges of glue dispensing nozzles are often detected by human eye observation, and then polished. However, human eye observation detection not only has low detection efficiency, but is also prone to errors and omissions. Therefore, a detection device for glue dispensing nozzles is urgently needed to solve the above problems. Utility Model Content

[0021] In this embodiment: the driving mechanism includes a motor 17 fixedly mounted on the bottom of the base 1, the output shaft of the motor 17 is fixedly connected to a threaded rod 18, the outer periphery of the threaded rod 18 is threadedly connected to a threaded sleeve 19, the top of the threaded sleeve 19 is fixedly connected to a connecting rod 20, and the top of the connecting rod 20 is fixed to the bottom of the L-shaped sliding plate 7; a rectangular guide hole is provided on the base 1, and the connecting rod 20 passes through the rectangular guide hole; the rectangular guide hole is provided to guide the movement of the connecting rod 20; the reciprocating mechanism includes a rotating shaft inserted into the L-shaped sliding plate 7, the front of the rotating shaft is fixedly connected to a disc 9, the back of the rotating shaft is fixedly connected to a toothed disc 16, the top of the base 1 is fixedly connected to a toothed plate 8, and the toothed plate 8 and the toothed plate 8 are fixed to each other. The disk 16 is meshed for transmission, and a rotating block 21 is fixedly connected to the front of the disk 9; the detection mechanism includes a rectangular hollow sleeve 10 sleeved on the periphery of the rotating block 21, a fixed plate 11 is fixedly connected to the front of the rectangular hollow sleeve 10, a detection plate 12 is arranged below the fixed plate 11, a spring 13 is fixedly connected between the fixed plate 11 and the detection plate 12, and an upper sleeve 14 and a pressure block 15 are fixedly connected to the bottom of the detection plate 12; a plurality of first guide rods are fixedly connected to the top of the detection plate 12, and the top end of the first guide rod movably passes through the fixed plate 11; guide sleeves are fixedly connected to both sides of the rectangular hollow sleeve 10, a second guide rod is fixedly connected to the bottom inner wall of the L-shaped sliding plate 7, and the guide sleeves are movably sleeved on the periphery of the second guide rod.

[0022] Working principle: First, place the dispensing nozzles to be tested one by one on top of the conical positioning block 5, which plays the role of positioning the dispensing nozzles. The running motor 17 drives the threaded rod 18 to rotate. The rotation of the threaded rod 18 drives the threaded sleeve 19, the connecting rod 20 and the L-shaped sliding plate 7 to slide horizontally as a whole. In the process of horizontal sliding, the toothed disc 16 and the toothed plate 8 engage and drive the rotating shaft and the disc 9 to rotate. The rotation of the disc 9 drives the rotating block 21 to rotate. The rotation of the rotating block 21 drives the rectangular hollow sleeve 10, the fixed plate 11, and the detection The plate 12 and other components reciprocate up and down as a whole. When it moves downward to the bottom, the detection plate 12 just moves to the top of the next conical positioning block 5, and the upper top sleeve 14 is pressed on the top of the dispensing nozzle. At the same time, the pressure block 15 presses the pressure sensor 3. When the dispensing nozzle is qualified, the pressure value on the pressure sensor 3 is the standard value. When the dispensing nozzle has burrs and burrs, there is a certain deviation in the pressure of the pressure block 15 pressing the pressure sensor 3. At this time, the corresponding display module 6 corresponding to the pressure sensor 3 displays the corresponding unqualified mark. When the practical device is working, when testing one of the dispensing nozzles, it is convenient to replace the last tested dispensing nozzle. Not only is the overall detection efficiency high, but also avoids detection errors and omissions.
