Embodiment 1

[0021] Example 1 as figure 1 , 2 As shown, a high-precision fluid supply device includes a base body 1, a power device 2 installed on the base body 1 and a guide rail device 3 installed on the base body 1, and also includes a The transmission device 4 on the guide rail device 3, the transmission device 4 includes a connecting block 41 installed on the guide rail device 3, a screw device 42 and a plunger rod 43 connected by the connecting block 41, the One end of the screw device 42 is connected with the power device 2, the other end of the screw device 42 is connected with the plunger rod 43, and the power device 2 will rotate through the screw device 42 Transformed into the linear reciprocating motion of the plunger rod 43, the base body 1 is also connected with a plunger cylinder 5, and the plunger cylinder 5 is provided with a glue inlet valve actuator 6 and a glue outlet valve actuator. Mechanism 7 (the valve actuator here is a combination of a ball valve and an actuator...

Embodiment 2

[0029] Example 2 as image 3 , 4 As shown, it is a double glue-out working mode setting. The scheme of embodiment 2 is a better technical scheme expanded on the basis of the scheme of above-mentioned embodiment 1, and the principle of glue-out and material supply is roughly the same as that of embodiment 1. The difference in structure is that the plunger cylinder body 5 in embodiment 2 is provided with two cylinders, on which are connected two parallel glue inlet valve actuators 6 and two parallel glue outlet valve actuators 7, Correspondingly, there are two parallel transmission devices 4, and the two transmission devices 4 are respectively provided with a transmission gear 8 at one end connected to the power device 2, and the transmission gears 8 are meshed with each other, so that When one transmission device 4 drives the corresponding plunger rod 43 to move forward, the other transmission device 4 drives the corresponding plunger rod 43 to move backward. That is to say, ...

Embodiment 3

[0031] Example 3 as Figure 5 As shown, it differs from Embodiment 1 in that the glue-in valve actuator 6 and the glue-out valve actuator 7 are changed from a combination of a ball valve and an actuator to a combination of a cylinder and a seal. The glue cylinder mechanism 60 and the glue outlet cylinder mechanism 70 respectively replace the glue inlet valve actuator 6 and the glue outlet valve actuator 7 in Embodiment 1. Embodiment 3 ensures that the technical function and effect are the same as Embodiment 1. Compared with Embodiment 1, it has the advantages of compact structure, more convenient installation, repair and maintenance.

Abstract

The invention provides a high-precision fluid supply device. The high-precision fluid supply device comprises a base body, a power device mounted on the base body and a guide rail device mounted on the base body and further comprises a transmission device arranged on the guide rail device, wherein the transmission device comprises a connecting block mounted on the guide rail device, a screw rod connected through the connecting block and a plunger rod, one end of the screw rod is connected with the power device, the other end of the screw rod is connected with the plunger rod, rotating movementis converted to the linear reciprocating movement of the plunger rod by the power device through the screw rod, a plunger cylinder is further connected to the base body, and an adhesive inlet valve executing mechanism and an adhesive outlet valve executing mechanism are arranged on the plunger cylinder. The supply device has the advantages of high pressure, stable performance, high adhesive discharging precision, long durability and high working efficiency.

Description

technical field [0001] The invention relates to the technical field of fluid feeding, in particular to the technical field of fluid feeding equipment used in the glue filling process of the LED manufacturing industry. Background technique [0002] In recent years, the LED industry has developed rapidly, and the requirements for LED product manufacturing technology are getting higher and higher. Among them, the feeding device that is often used in the glue filling process mainly includes gear pumps, which rely on the meshing motion of gears in a closed pump cylinder. The power is used to complete the feeding and discharging of the fluid. The defect is that it is not suitable for glue with fillers, because some glues contain materials such as hard silica and quartz powder, which are easy to If it is worn by the filling, the error will increase and the accuracy will decrease after a long time. Another kind of feeding device is a screw pump, which uses the rotary motion of the ...
