The phenomenon of eclipse causes the inside of the coating to appear, bubbles, and even condense into large bubbles, which also increases the product defect rate. 5th, such as US6688580, US6669057, US6520382, US6257445 US606〇125, US5873528 patents have been designed to avoid the problem, but there is only one form of control device, no replaceability or a type of knot. And the previous case will close the ball or the valve needle to dispense the glue ^ = impact contact will affect the seal f. t [Summary of the Invention] The dispensing device of the invention is a pneumatic piston device that controls the flow of the glue and controls the dispensing speed. The piston device is combined with the local device to fine the upper and lower jaws. The valve needle device is opened and closed, and the screw device controls the valve needle device at least—opening the H. The main advantage of the invention is that the rubber material is reduced in the valve needle line m and the axis is reduced. 5 1283466 The probability of occurrence of sedimentation blockage. 2 · The throttle pin has a curved profile on the side of the valve pin, which can be replaced according to different requirements to achieve the required flow characteristics. 3 · The ejector pin and the piston move relative to each other in the hollow flow path, and the suction and push functions are formed by volume change to avoid the occurrence of dripping and rubber clogging during operation. The benefits created by the present invention are as follows: The choice of material flow diversity valve can be improved

Back-to-back plus, different--, in the 1C volume continues to shrink, the function increases; C-packaging technology I / O number or speed transmission wheel 嶋 wheel ^ application 4 growth trend, high-end packaging will drive the overall packaging market The point and the function of the function will be based on the detailed structure of the Axisaki embodiment (4). [Embodiment] (4) to the fourth figure 'The paste structure of this creation, mainly the liquid-liquid needle device 10 to control the flow rate of the glue , Lin Biao ^ Device 20 to control the dispensing speed. The hydraulic pressure piston is connected to the hydraulic valve needle 10, the main red and white 7 valve needle 103, the valve seat 104 and the two needles, the body cover 1〇2, the valve body 105. The needle tube 1〇1 and the body cover 1〇2-6 1283466 are integrally formed and assembled under the valve body 105, and a valve seat ι 4 is provided at the intersection of the two to have a hollow flow passage 103b inside (see the third figure). Or the valve 103 of the fourth figure is incorporated in the valve body 105. A hydraulic rubber material supply port 105a is opened on one side of the valve body 1〇5, so that the rubber material can be injected into the valve needle 丨〇3 from the supply port i〇5a, and then has a type and above curve formed on the side of the valve needle 103. The contour orifice 103a flows into the hollow flow passage 10b, and then flows out through the inclined pipe 101 that communicates with the hollow flow passage. The τ gas piston device 20 includes a piston 2〇1, a spring 202, a top cover #203, an adjustment screw 204, a thimble 205, and a cylinder 206. The cylinder 206 is assembled above the valve body 105, and a piston 201 is disposed therein for use as a piston movement guide; the piston 201 is connected to the top end connecting portion 1〇3c of the valve needle 103 to move up and down. In addition, the upper portion of the cylinder 206 is closed by a top cover 203, so that the spring 202 is disposed between the top surface of the piston 201 and the top cover 203, and the piston 2〇3 is pressed to be in a position below the cylinder 206; the function of the spring 202 is Forced on the top surface of the piston 2〇1, the valve is in the off state when there is no air pressure state, so the spring 2〇2 is kept in contact with the piston 201 when the matching; the adjusting screw 204 protrudes into the cylinder 206 from above the top cover 203" The ejector pin 205 fixed at the bottom thereof penetrates into the hollow flow passage 201b in the tubular body 2〇ia below the piston 201. The hollow flow passage 201b is an adjusting screw 204 that communicates with the hollow flow passage 1〇& of the valve needle 103. The rotating screw screw 204 engages with the fixing nut 207 on the top cover 203 to adjust the depth at which the thimble 205 penetrates into the hollow flow path 2〇lb. Referring to the third figure, when the air inlet 206 & of the cylinder 206 has a pneumatic supply (as indicated by the arrow), the piston 2〇1 is pushed upward to move the compression spring 2〇2, and the valve needle 103 is moved up. The throttle port 1 () 3a of the valve needle 1Q3 is supplied to the mouth of the positive valve body 105, and the rubber material flows into the hollow flow path dirty and 206b; the valve needle 103 is used to ride the supply port with the glue body 1〇5_ Between the different contours, the money flow adjustment Wei (see the fifth picture, the following also says 1283466. = field competitiveness. And the number of parts of the gamma, the device, can increase the product's additional compensation.
