Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of dispensing machines, and particularly relates to a dispensing machine for coupling a cantilever beam waveguide silicon optical engine. Background Art
[0002] Traditional dispensing machine designs such as Figure 1 and Figure 2 are shown. When the dispensing machine dispenses glue, high-pressure air pushes the piston in the dispensing tube downward to squeeze the air between the piston and the glue. The air is compressed to squeeze the glue, so that the glue emerges from the dispensing needle tip. And a part of the glue emerging from the dispensing needle tip will be dispensed on the product (for example: at the coupling gap between the silicon optical engine and the fiber optic array). When the dispensing machine dispenses the next product, due to the inertia of the compressed air, the glue continuously emerges from the dispensing needle tip, which is not conducive to controlling the amount of glue. Therefore, the dispensing machine usually has a vacuum suction function, so that the glue in the dispensing needle tip is sucked upward, preventing the glue from continuously emerging. Since there is air between the piston and the glue, the air is high-pressure air when compressed (the piston moves downward), and the air is low-pressure air when stretched (the piston moves upward). This design causes air to enter the glue when the piston reciprocates up and down in the dispensing tube. In addition, foreign objects (tiny plastic particles) will enter the glue due to the friction between the reciprocating piston and the dispensing tube. For a silicon optical engine, especially a waveguide with a cantilever beam structure, if there is air inside the optical glue, it will lead to poor optical power, and the air expands at high and low temperatures to damage the cantilever beam, while the tiny plastic particles in the glue will cause light blocking, ultimately resulting in a low product yield. Summary of the Utility Model
[0003] The technical problem to be solved by the utility model is to provide a dispensing machine for coupling a cantilever beam waveguide silicon optical engine to overcome the above-mentioned deficiencies in the prior art.
[0004] The technical solution of the utility model to solve the above technical problem is as follows: A dispensing machine for coupling a cantilever beam waveguide silicon optical engine includes: a dispensing tube and a suction tube connected to the dispensing main machine. The working end of the dispensing tube is provided with a dispensing needle tip. A main piston is slidably arranged in the dispensing tube. The working end of the suction tube is communicated with the inner cavity of the dispensing needle tip through the side of the dispensing needle tip. A suction piston is slidably arranged in the suction tube. The dispensing main machine controls the suction piston to move in the suction tube to suck the glue in the dispensing needle tip, and the main piston does not perform a suction action during this process.
[0005] On the basis of the above technical solution, the utility model can be further improved as follows.
[0006] Further, when the dispensing main machine controls the suction piston to move in the suction tube to suck the glue in the dispensing needle tip, the suction air pressure applied by the dispensing main machine on the suction piston is smaller than the air pressure applied by the dispensing main machine on the main piston.
[0007] Furthermore, the main piston and the suction piston synchronously extrude the glue under the air pressure of the dispensing main machine. During the dispensing process, the air pressure exerted by the dispensing main machine on the main piston is greater than that on the suction piston.
[0008] Furthermore, a slender channel communicating with its inner cavity branches out from the side of the dispensing needle tip, and the slender channel communicates with the working end of the suction pipe.
[0009] Furthermore, the slender channels are obliquely distributed upward.
[0010] The beneficial effects of the present utility model are as follows: During the dispensing process, the dispensing main machine introduces high-pressure air (compressed gas) into the dispensing tube to exert pressure on the main piston, thereby controlling the main piston to move downward and extrude the glue, allowing the glue to enter the dispensing needle tip and dot the glue on the product. After each dispensing is completed, the dispensing main machine controls the suction piston to move (move upward) in the suction pipe to suck back the glue in the dispensing needle tip to prevent the glue from continuously flowing out of the dispensing needle tip. During the process of the suction piston sucking back the glue, the main piston does not perform a suction (upward movement) action. Therefore, the movement of the main piston can be reduced, and there is no air between the main piston and the glue, thereby avoiding air from entering the glue and also reducing the mixing of particulate foreign matters in the glue, improving the coupling yield of the cantilever beam waveguide silicon optical engine.

[0017] The principles and features of the present utility model are described below with reference to the accompanying drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.
[0018] Embodiment 1
[0019] As Figure 3 , Figure 4 shown, a dispensing machine for coupling a cantilever waveguide silicon optical engine includes: a dispensing main machine 1, a dispensing tube 2 and a suction tube 3. Among them, the dispensing tube 2 and the suction tube 3 are respectively connected to the dispensing main machine 1. The working end of the dispensing tube 2 is provided with a dispensing needle 4. A main piston 5 is slidably arranged in the dispensing tube 2. The working end of the suction tube 3 is communicated with the inner cavity of the dispensing needle 4 through the side of the dispensing needle 4. A suction piston 6 is slidably arranged in the suction tube 3;
[0020] During the dispensing process, the dispensing main machine 1 introduces high-pressure air (compressed gas) into the dispensing tube 2 to apply pressure to the main piston 5, thereby controlling the main piston 5 to move downward and extrude the glue, allowing the glue to enter the dispensing needle 4 and dot the glue on the product. After each dispensing is completed, the dispensing main machine 1 controls the suction piston 6 to move (move upward) in the suction tube 3 to suck back the glue in the dispensing needle 4 to prevent the glue from continuously flowing out of the dispensing needle 4. During the process of the suction piston 6 sucking back the glue, the main piston 5 does not perform a suction (upward movement) action. Therefore, the movement of the main piston 5 can be reduced, so that there is no air between the main piston 5 and the glue, thereby preventing air from entering the glue, and it can also reduce the mixing of particulate foreign matters in the glue, improving the coupling yield of the cantilever waveguide silicon optical engine.
[0021] Embodiment 2
[0022] As Figure 3 , Figure 4 shown, this embodiment is a further improvement on the basis of Embodiment 1, specifically as follows:
[0023] During the process of the dispensing main machine 1 controlling the suction piston 6 to move (move upward) in the suction tube 3 to suck back the glue in the dispensing needle 4, the suction air pressure applied by the dispensing main machine 1 on the suction piston 6 is smaller than the air pressure applied by the dispensing main machine 1 on the main piston 5. During the suction process, the main piston 5 stops working and the suction piston 6 works, and the air pressure is less than that of the main piston 5. The purpose is to generate a suction force to prevent the glue from continuously flowing out of the dispensing needle 4 when the dispensing action stops.
[0024] In addition, during the dispensing process in which the main piston 5 and the suction piston 6 synchronously extrude the glue (move downward) under the air pressure of the dispensing main machine 1, the air pressure applied by the dispensing main machine 1 on the main piston 5 is greater than the air pressure applied on the suction piston 6. During the dispensing process, the air pressure of the main piston 5 is greater than that of the suction piston 6. The purpose is to prevent the glue in the suction tube 3 from being dotted on the product because there is air and plastic microparticles in the glue in the suction tube 3.
[0025] Embodiment 3
[0026] As Figure 3 , Figure 4As shown in the figure, this embodiment is a further improvement based on Embodiment 1 or 2, and the specific content is as follows:
[0027] A slender channel 410 communicating with its inner cavity branches out from the side of the dispensing needle head 4. The slender channel 410 is communicated with the working end of the suction pipe 3, which is convenient for controlling the amount of glue suction. The slender channel 410 is obliquely distributed upward.
[0028] Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
