At this time, the glue 9 is squeezed to the side of the dispensing head 120 due to the small distance between the dispensing head 120 and the cable 8. Next, as shown in fig. 5B, the transferring device 14 drives the dispensing jig 10 to move (in the X-axis direction in the figure), so as to coat the glue 9 on the side of the dispensing head 120 onto the cable 8. In the present embodiment, the direction of the curved surface of the arc surface 123 of the dispensing head 120 is the same as the moving direction of the transfer device 14. That is, when the glue 9 is pushed to the side of the dispensing head 120, the glue 9 is located on the curved surface of the arc surface 123. Therefore, the glue 9 flows down to the top end of the dispensing head 120 along the arc surface 123 and is coated on the cable 8.

The cable 8 may be soldered to the circuit board 7 poorly, resulting in a protrusion or a depression. Therefore, as shown in fig. 5C and 5D, when the transferring device 14 drives the dispensing jig 10 to move to the protrusion of the cable 8, the arc surface 123 of the dispensing head 120 of the dispensing jig 10 contacts the protrusion, and the dispensing head 120 moves upward from the protrusion 127 disposed in the elongated groove 112 along with the curved surface of the arc surface 123. At this time, the glue 9 on the curved surface of the arc surface 123 is also applied to the cable 8 along with the protrusion of the cable 8. Similarly, when the transferring device 14 drives the dispensing jig 10 to move to the recess of the cable 8, the dispensing head 120 of the dispensing jig 10 moves downward and leans against the cable 8 due to its own gravity, so that the glue 9 can be coated on the recess of the cable 8. Therefore, the utility model discloses a glue dispensing jig permeable convex dispensing head coats the cable with the colloid evenly on to permeable convex dispensing head and the microscler recess and the protruding structure of mutually matchd coat unevenness on the cable evenly, not only can improve the point and glue efficiency, also can reduce cost.
