Description
[ technical field ] A method for producing a semiconductor device
The invention relates to an automatic dispenser, in particular to a drop-fixing device of the automatic dispenser.
[ background of the invention ]
An automatic dispenser is generally used in a coating process of various parts such as semiconductor packages and fixing of electronic parts of circuit boards. The automatic glue dispenser stops dispensing after the dispensing cycle is finished, the needle head returns to the original position, and the automatic glue dispenser does not act before the action of the next dispensing cycle.
However, since the glue dispensed by the automatic glue dispenser has a curing time, for example, the thermosetting glue with the brand number LN-2250 is completely cured within 3 minutes, after the glue is dispensed in the previous cycle, when the needle head stays at the original point for a time greater than or equal to the curing time of the glue, the glue remaining on the needle head is air-dried and cured, the needle head is blocked and does not smoothly discharge the glue, which affects the glue discharging amount of the glue in the next cycle, and causes quality abnormality that the glue cannot be tightly combined and loosened due to glue shortage.
In view of the above, there is a need to develop a drop-fixing device of an automatic dispenser to solve the problem that the residual glue on the needle head is solidified to block the needle head.
[ summary of the invention ]
Therefore, the invention aims to provide a drop-fixing device of an automatic glue dispenser, which can automatically discharge glue before residual glue is solidified, prevent needle head blockage and prevent blockage and glue discharging unsmooth.
In order to achieve the above object, the present invention provides a drop-fixing device of an automatic dispenser, wherein the automatic dispenser comprises a glue inlet pipe and a needle, the drop-fixing device comprises:
the electromagnetic valve is arranged to control the rubber inlet channel to feed and discharge rubber;
the time relay is set to control the dispensing time and the dispensing delay time of the needle head, and the dispensing delay time is less than the curing time of the glue;
and the control unit sends signals to the electromagnetic valve and the time relay to control the electromagnetic valve and the time relay to work.
Optionally, the drop-fixing device further comprises a glue dropping container arranged below the needle of the automatic glue dispenser and used for containing glue dropped from the needle.
Optionally, the fixed-drop device of the automatic dispenser further comprises an air pressure regulating valve, which is arranged on the glue inlet pipeline and controls the air pressure in the glue inlet pipeline.
Optionally, the drop-fixing device of the automatic dispenser further comprises a one-way valve arranged on the glue inlet pipeline and used for controlling the glue inlet pipeline to discharge air along the glue inlet direction.
Optionally, the dispensing time of the needle is 1 second, and the dispensing delay time is 120 seconds.
Compared with the prior art, the fixed-drop device of the automatic dispenser is simple in structure, the solenoid valve and the time relay are arranged to control the glue-dispensing delay time of the needle head, so that glue on the needle head can be automatically discharged before being solidified, the needle head is prevented from being blocked, the phenomena of blocking and unsmooth glue discharging are prevented, the glue-dispensing quantity of the next period is not influenced, and the quality of products is ensured.
[ description of the drawings ]
FIG. 1 is a block diagram of a dispensing device of an automatic dispenser according to the present invention.
FIG. 2 is a block diagram of a dispensing device of an automatic dispenser according to a preferred embodiment of the present invention.
[ detailed description ] embodiments

the electromagnetic valve 100 is arranged to control the rubber inlet channel to enter rubber and discharge the rubber;
the time relay 200 is set to control the dispensing time and the dispensing delay time of the needle head, the dispensing time of the needle head is the time used by the needle head for dispensing each time, the dispensing delay time is the time from glue bonding to the beginning of dispensing of the needle head after the glue bonding in the last period, the dispensing delay time is less than the curing time of the glue, more specifically, the time relay 200 starts timing after receiving the starting signal, and the working contact of the time relay 200 performs opening or closing after the timing is finished;
and the control unit 300 sends signals to the solenoid valve 100 and the time relay 200, and controls the solenoid valve 100 and the time relay 200 to work.
In a preferred embodiment, the dispensing device further comprises a glue container disposed below the needle of the automatic dispenser 400, and when the next product is not placed on the automatic dispenser 400 in time, the glue container contains glue dispensed from the needle, so as to prevent the glue from directly falling onto the work platform.
Referring to fig. 2, fig. 2 is a block diagram illustrating a dispensing device of an automatic dispenser according to a preferred embodiment of the present invention. In a preferred embodiment, the drop-fixing device of the automatic dispenser further includes an air pressure adjusting valve 500 disposed on the glue inlet pipe for controlling the air pressure in the glue inlet pipe, so as to adjust the air pressure for discharging glue and adjust the glue discharging amount.
In a preferred embodiment, the dispensing device of the automatic dispenser further includes a one-way valve 600 disposed on the glue inlet pipe for controlling the air outlet of the glue inlet pipe along the glue inlet direction, so as to prevent the air outlet along the reverse direction of the dispensing direction from affecting the glue outlet amount during dispensing.
