Description

Technical Field

[0001] This utility model relates to the field of relay processing technology, specifically to a relay encapsulation dispensing mechanism. Background Technology

[0002] The relay structure is a core component in physical devices for realizing circuit control, mainly consisting of an electromagnet system and a contact system. The electromagnet system is composed of a coil wound around an iron core. When energized, the resulting magnetic field drives the armature to move, thereby closing the contact system and achieving the function of switching on and off. During relay manufacturing, a dispensing mechanism is needed for encapsulation. However, with current dispensing mechanisms, the encapsulating adhesive may partially solidify due to low temperature before extrusion, leading to poor adhesive extrusion. Therefore, there is an urgent need to design a relay encapsulation dispensing mechanism to solve the above problems. Utility Model Content

[0003] The purpose of this invention is to provide a relay encapsulation dispensing mechanism to address the aforementioned shortcomings in the prior art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A relay encapsulation dispensing mechanism includes a mounting bracket, a cylindrical body fixed to the bottom outer wall of the mounting bracket, a piston disposed inside the cylindrical body, a pull rod fixed to the top of the piston, a driving mechanism disposed at the top of the pull rod, a valve assembly one fixed to the bottom of the cylindrical body, a valve assembly two fixed to the bottom end of the cylindrical body, a heating layer disposed on the outer wall of the cylindrical body, a heat insulation layer disposed on the outer wall of the heating layer, and a protective layer disposed on the outer wall of the heat insulation layer.

[0006] Furthermore, the drive mechanism includes an electric telescopic rod fixed to the top of the mounting bracket, a crossbar fixed to the top of the rod, and the output end of the electric telescopic rod fixed to the crossbar.

[0007] Furthermore, a guide sleeve is fixed to the top outer wall of the mounting bracket, and a guide post is fixed to the top of the crossbar, with the guide post movably inserted into the inside of the guide sleeve.

[0008] Furthermore, the valve assembly includes a circular tube threaded to the bottom side wall of the cylinder, the inside of the circular tube having a conical cavity, the inside of the conical cavity having a hemispherical end, and the inside of the circular tube having a spring.

[0009] Furthermore, a guide block is provided inside the circular tube, the guide block is integrally formed with the hemispherical end, and the side wall of the guide block is provided with a notch.

[0010] Furthermore, the bottom end of the valve assembly two is threadedly connected to a dispensing nozzle, and one end of the round tube is integrally formed with a threaded tube.

[0011] In the above technical solution, the relay encapsulation dispensing mechanism provided by this utility model has the following advantages: by setting a heating layer, a heat insulation layer and a protective layer on the outside of the cylinder, the encapsulating adhesive entering the cylinder is less likely to coagulate, thereby avoiding the situation of poor extrusion of the encapsulating adhesive; by setting valve assembly one and valve assembly two in cooperation, valve assembly one can only allow the encapsulating adhesive to enter the cylinder in one direction, and valve assembly two can only allow the encapsulating adhesive to flow out of the cylinder in one direction, thereby making the extrusion of the encapsulating adhesive more reliable.

Detailed Implementation

[0019] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0020] like Figure 1-4As shown in the figure, the relay encapsulation dispensing mechanism provided in this embodiment of the utility model includes a mounting frame 1, a cylindrical body 2 fixed to the bottom outer wall of the mounting frame 1, a piston 3 disposed inside the cylindrical body 2, a pull rod 12 fixed to the top of the piston 3, a driving mechanism disposed at the top of the pull rod 12, a valve assembly 4 fixed to the bottom of the cylindrical body 2, a valve assembly 5 fixed to the bottom end of the cylindrical body 2, a heating layer 7 disposed on the outer wall of the cylindrical body 2, a heat insulation layer 8 disposed on the outer wall of the heating layer 7, and a protective layer 9 disposed on the outer wall of the heat insulation layer 8.

[0021] Specifically, in this embodiment, a mounting bracket 1 is included. A cylindrical body 2 is fixed to the bottom outer wall of the mounting bracket 1. The cylindrical body 2 is made of aluminum alloy with high thermal conductivity. A piston 3 is installed inside the cylindrical body 2. A pull rod 12 is fixed to the top of the piston 3. A driving mechanism is installed on the top of the pull rod 12. The driving mechanism drives the piston 3 to move through the pull rod 12. A valve assembly 4 is fixed to the bottom of the cylindrical body 2. The valve assembly 4 allows the encapsulating adhesive to enter the cylindrical body 2 in one direction only. A valve assembly 5 is fixed to the bottom end of the cylindrical body 2. The valve assembly 5 allows the encapsulating adhesive to flow out of the cylindrical body in one direction only. 2. Furthermore, the encapsulating adhesive is heated to form a fluid before entering the cylinder 2. For example, if epoxy resin is used as the encapsulating adhesive, a heating layer 7 is provided on the outer wall of the cylinder 2. The heating layer 7 is formed by wrapping heating wires. An insulation layer 8 is provided on the outer wall of the heating layer 7. The insulation layer 8 is made of pearl cotton. A protective layer 9 is provided on the outer wall of the insulation layer 8. The protective layer 9 is made of PP material. This allows the heating layer 7 to heat the cylinder 2 after being energized. The number of cylinders 2 is at least one, or there can be multiple cylinders, so that multiple dispensing mechanisms can encapsulate multiple relays simultaneously.

[0022] The present invention provides a relay encapsulation dispensing mechanism, which, by setting a heating layer 7, a heat insulation layer 8 and a protective layer 9 on the outside of the cylinder 2, makes it less likely for the encapsulating adhesive to coagulate inside the cylinder 2, thereby avoiding the situation where the encapsulating adhesive is not extruded smoothly.

[0023] In another embodiment of this utility model, the driving mechanism includes an electric telescopic rod 10 fixed to the top of the mounting frame 1, a crossbar 11 fixed to the top of the pull rod 12, and the output end of the electric telescopic rod 10 fixed to the crossbar 11. The electric telescopic rod 10 drives the crossbar 11 to move. A guide sleeve 15 is fixed to the top outer wall of the mounting frame 1, and a guide post 13 is fixed to the top of the crossbar 11. The guide post 13 is movably inserted into the inside of the guide sleeve 15, and the guide post 13 makes the crossbar 11 more stable when it moves.

[0024] In another embodiment of this utility model, valve assembly 4 includes a circular tube 16 threadedly connected to the bottom side wall of the cylinder 2. The inside of the circular tube 16 communicates with the cylinder 2. A conical cavity 18 is provided inside the circular tube 16, and a hemispherical end 19 is provided inside the conical cavity 18. A spring 21 is provided inside the circular tube 16, and the hemispherical end 19 is kept in a cooperating state with the conical cavity 18 by the elastic force of the spring 21. A guide block 17 is provided inside the circular tube 16, and the guide block 17 is integrally formed with the hemispherical end 19. A notch 20 is provided on the side wall of the guide block 17, and the notch 20 allows the encapsulating adhesive to pass through the guide block 17. Flow; the bottom end of valve assembly 2 5 is threadedly connected to a dispensing nozzle 6, and one end of the round tube 16 is integrally formed with a threaded tube 14. Valve assembly 2 5 is the same as valve assembly 1 4, but the threaded tube 14 of valve assembly 1 4 is far away from the cylinder 2, while the threaded tube 14 of valve assembly 2 5 is close to the cylinder 2, so that valve assembly 1 4 and valve assembly 2 5 can respectively control the entry and exit of the encapsulating adhesive into the cylinder 2. By setting valve assembly 1 4 and valve assembly 2 5 to cooperate, valve assembly 1 4 can only allow the encapsulating adhesive to enter the cylinder 2 in one direction, and valve assembly 2 5 can only allow the encapsulating adhesive to flow out of the cylinder 2 in one direction, thereby making the extrusion of the encapsulating adhesive more reliable.

[0025] Working principle: In use, the glue supply pipe is connected to the threaded pipe 14 of valve assembly 1. The electric telescopic rod 10 drives the crossbar 11 to move upward. The hemispherical end 19 inside valve assembly 1 is separated from the conical cavity 18 by pressure. The hemispherical end 19 inside valve assembly 2 cooperates with the conical cavity 18, so that the piston 3 draws the glue into the inside of the cylinder 2. When the electric telescopic rod 10 drives the piston 3 to press down, the hemispherical end 19 inside valve assembly 2 separates from the conical cavity 18, and the hemispherical end 19 inside valve assembly 4 cooperates with the conical cavity 18. At this time, the glue inside the cylinder 2 can be squeezed out from the glue outlet 6, so that the glue drips onto the part of the relay that needs to be sealed.

[0026] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
