Description of the invention: [Technical field to which the invention pertains] [0001] The present invention relates to a dispensing device. [Previous Technology] [0002] Dispensing devices are commonly used in the manufacturing industry to apply fluid colloidal materials, such as viscous resins, to a part to be machined for bonding to other parts. The dispensing device mainly includes a barrel and a dispenser. The barrel is filled with glue, and the compressed air enters the barrel through the valve, and the glue in the barrel is pushed into the dispenser through the discharge port at the lower end of the barrel. The dispenser includes a needle valve for accumulating glue and a needle for dispensing, and the control valve is connected to the needle valve for turning on or cutting off the glue supply. [0003] However, the unstable working pressure of the compressed air may cause the outflow speed of the glue to be uneven, which makes the dispensing amount uneven and affects the dispensing precision. At the same time, after the traditional control valve cuts off the supply of glue, the residual glue in the needle will still slowly flow out from the needle, forming a “drawing” phenomenon. The "drawing" phenomenon not only wastes the raw materials, but also does not require the glued parts to be contaminated by the processed parts. [Invention] [0004] In view of this, it is necessary to provide a higher dispensing precision and a quicker response speed. Dispensing device.

81後，對上述拆卸步驟進行逆操作，即可較為輕鬆地將 點膠裝置100復原。 [0029] 請一併參閱圖9和圖10，本發明實施方式二之點膠器81a 與實施方式一之點膠器81大致相同，其不同之處在於： 容膠腔8115a之形狀為圓柱形。閥芯817a之形狀亦為圓 柱形，閥芯817a遠離進膠口 8123a之一側壁與容膠腔 8115a之側壁之間存於間隙8124a，且閥芯817a靠近進膠 口 8123a之一侧壁與容膠腔8115a之側壁之間始終保持接 觸。當點膠器81 a處於圖9所示之開啟狀態時，閥芯817a 不封閉進膠口 8123a，膠液可從進膠道8121a流入容膠腔 8115a之上部，並經由間隙8124a進入容膠腔8115a之下 部，最後經針頭813a吐出。當需要停止出膠時，拉桿 815a迅速向上運動，從而帶動閥芯817a朝遠離針頭813a 之方向運動。當閥芯817a上端與容膠腔8115a之頂部相 接觸時，閥芯81 7a停止運動並關閉進膠口8123a。於此 過程中，容膠腔8115a内之壓力減小而對位於針頭813a 内之膠液產生一定之回吸效果，因此原本從針頭81 3 a流 出之膠液會被迅速切斷，不再流出。當需要重新出膠時 099117695 表單編號A0101 第12頁/共31頁 0992031414-0 201143912

The hose is used to connect the discharge pipe 65 and the feed nozzle 8116. The dispensing device 100 is assembled. [0027] Ο When in use, the motor 41 drives the screw 45 to rotate, so that the slider 46 drives the rotary member 47 to slide along the slide rail 48. The plug portion 632 of the pusher piston 63 fixed to the adapter 47 moves downward along the cavity 6211 to squeeze the glue, so that the glue flows from the cavity 6211 into the discharge pipe 65 and enters the dispensing through the nozzle 8116. 81. When the dispenser 81 is in the open state shown in Fig. 7, the spool 817 is located at a position between the first housing portion 8117 and the second housing portion 8118. At this time, the valve core 817 does not close the rubber inlet 8123, and the glue can flow from the rubber passage 8121 into the first receiving portion 811r, and enters the second receiving portion via the gap 8124 between the valve core 817 and the second receiving portion 8118. Ping 8118, finally spit out through the needle 813. ::5 Referring to FIG. 8 , when it is necessary to stop the glue, the motor 41 stops rotating, and the push piston 63 no longer squeezes the glue, and the piston rod 833 of the driving member 83 drives the rod 815 to move upward rapidly, thereby driving the spool. The 817 is moved away from the needle 813 to enter the first housing portion 8117. When the side wall of the spool 817 abuts against the wall of the second housing portion 81丨7, the spool 817 stops moving and closes the glue inlet 8123. During this process, the pressure of the valve core 817 on the glue in the first receiving portion 8117 is larger, and the partial glue is pushed into the intake channel 8121, and the pressure in the second receiving portion 8118 is decreased and the needle is located at the needle 813. The glue inside generates a certain sucking effect, so the winning liquid originally flowing out from the needle 813 will be cut off quickly, no longer flowing out. ^ When the need to re-(4), the piston rod 833 of the stirring member 83 drives the rod 815 to move downward. The valve anger 817 is moved toward the needle 813 to restore the open state shown in FIG. 099117695 Form No. Α〇 101 Page / Total 31 0992031414-0 201143912 [0028] After the dispensing device 100 is used for a period of time, the glue in the dispenser 81 may solidify and block circulation. In this case, the new dispenser 81 should be replaced in time. When replacing, the screw can be rotated in the reverse direction so that the screw no longer abuts against the first engaging portion 8113 of the needle valve 811. The support member 86 is then removed from the holder 20 to separate the dispenser 81 from the fixed block 85. Finally, the first lock 88 is reversely rotated so that the lock lever 883 is no longer in contact with the tie rod 815. At this time, the dispenser 81 can be removed from the second support plate 863 more easily. After replacing the new dispenser 81, the above disassembly steps can be reversed to restore the dispensing device 100 more easily.

The side walls of the glue chamber 8115a are always in contact. When the dispenser 81a is in the open state shown in FIG. 9, the valve core 817a does not close the glue inlet 8123a, and the glue can flow from the rubber passage 8121a into the upper portion of the adhesive cavity 8115a, and enter the cavity through the gap 8124a. Below the 8115a, it is finally spit out through the needle 813a. When it is desired to stop dispensing, the pull rod 815a moves up quickly, thereby causing the spool 817a to move away from the needle 813a. When the upper end of the spool 817a comes into contact with the top of the caulking chamber 8115a, the spool 81 7a stops moving and closes the inlet port 8123a. During this process, the pressure in the glue chamber 8115a is reduced to produce a certain sucking effect on the glue located in the needle 813a, so the glue originally flowing from the needle 81 3 a is quickly cut off and no longer flows out. .
