Description

Technical Field

[0001] This utility model relates to the field of glue extraction technology, specifically a glue extraction device for PCB board production and processing. Background Technology

[0002] Currently, when Humiseal UV adhesive is packaged for the Geely project, the users manually pour it from a large bucket into a 2.5L small bucket, which easily leads to varying degrees of adhesive waste.

[0003] Therefore, a glue extraction device for PCB board production and processing is needed to improve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a glue extraction device for PCB board production and processing, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A glue extraction device for PCB board manufacturing includes a suction cylinder, a piston plate slidably disposed inside the suction cylinder, a sliding rod fixedly disposed at the upper end of the piston plate, a pressing rod fixedly disposed at the upper end of the sliding rod, a limiting cylinder one fixedly disposed at the lower end of the suction cylinder, a glue suction tube fixedly disposed at the lower end of the limiting cylinder, a limiting cylinder two fixedly disposed at the lower end of one side of the suction cylinder, and a glue discharge tube fixedly disposed on one side of the limiting cylinder two.

[0007] As a preferred embodiment of this utility model, the limiting cylinder is provided with a spring and a sealing ball head inside, and the spring and the sealing ball head are fixedly connected.

[0008] As a preferred embodiment of this utility model, one end of the spring is fixed to the upper end of the limiting cylinder, and the sealing ball head is attached to one end of the suction tube.

[0009] As a preferred embodiment of this utility model, the limiting cylinder II is provided with spring II and sealing ball II inside, and spring II and sealing ball II are fixedly connected.

[0010] As a preferred embodiment of this utility model, one end of the second spring is fixed to the upper end of the second limiting cylinder, and the second sealing ball head is fitted and connected to the suction cylinder opening.

[0011] As a preferred embodiment of this utility model, a spiral fixing ring is fixedly installed at the lower end of the suction cylinder, and the spiral fixing ring is threadedly connected to the opening of the glue bucket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, by inserting the suction tube into the glue bucket and fixing it by rotating the spiral fixing ring, the pressing rod can be pressed up and down, thereby driving the piston plate to move up and down inside the suction cylinder to draw glue through the sliding rod. When the piston plate moves up, the inside of the suction cylinder is under negative pressure, and the glue enters the suction cylinder through the suction tube, which pushes open the sealing ball head one. The spring two drives the sealing ball head two to block the outlet of the suction cylinder, thereby preventing the glue from flowing back. When pressed down, the spring one drives the sealing ball head one to block the suction tube, thereby pushing open the sealing ball head two and flowing out from the glue outlet tube.

[0024] Please see Figure 1-4 This utility model provides a technical solution:

[0025] A glue extraction device for PCB board manufacturing includes a suction cylinder 3, a piston plate 4 slidably disposed inside the suction cylinder 3, a sliding rod 2 fixedly disposed at the upper end of the piston plate 4, a pressing rod 1 fixedly disposed at the upper end of the sliding rod 2, a limiting cylinder 5 fixedly disposed at the lower end of the suction cylinder 3, a glue extraction tube 8 fixedly disposed at the lower end of the limiting cylinder 5, a limiting cylinder 11 fixedly disposed at the lower end of one side of the suction cylinder 3, and a glue dispensing tube 12 fixedly disposed at one side of the limiting cylinder 11. By inserting the glue extraction tube 8 into the glue container and then fixing it by rotating the spiral fixing ring 10, the pressing rod 1 can be pressed up and down, thereby driving the piston plate 4 to move up and down inside the suction cylinder 3 to extract glue through the sliding rod 2.

[0026] When the piston plate 4 moves upward, the suction cylinder 3 is under negative pressure. The glue is pushed open by the suction tube 8 and enters the suction cylinder 3. The spring 13 drives the sealing ball 9 to block the outlet of the suction cylinder 3, thereby preventing the glue from flowing back. When pressed down, the spring 6 drives the sealing ball 7 to block the suction tube 8, thereby pushing open the sealing ball 9 and flowing out from the glue outlet tube 12.

[0027] As an example of this utility model, the limiting cylinder 5 is provided with a spring 6 and a sealing ball head 7 inside, and the spring 6 and the sealing ball head 7 are fixedly connected.

[0028] As an example of this utility model, one end of the spring-6 is fixed to the upper end of the limiting cylinder-5, and the sealing ball head-7 is attached to one end of the suction tube-8.

[0029] As an example of this utility model, the limiting cylinder 11 is provided with a spring 13 and a sealing ball head 9 inside, and the spring 13 and the sealing ball head 9 are fixedly connected.

[0030] As an example of this utility model, one end of the second spring 13 is fixed to the upper end of the second limiting cylinder 11, and the second sealing ball head 9 is fitted and connected to the suction cylinder 3.

[0031] As an example of this utility model, a spiral fixing ring 10 is fixedly installed at the lower end of the suction cylinder 3, and the spiral fixing ring 10 is threadedly connected to the mouth of the glue bucket.

[0032] Working principle: When in use, insert the suction tube 8 into the glue bucket, and then fix it by rotating the spiral fixing ring 10. Then press the pressing rod 1 up and down, thereby driving the piston plate 4 to move up and down inside the suction cylinder 3 through the sliding rod 2 to suck up glue.

[0033] When the piston plate 4 moves upward, the suction cylinder 3 is under negative pressure. The glue is pushed open by the suction tube 8 and enters the suction cylinder 3. The spring 13 drives the sealing ball 9 to block the outlet of the suction cylinder 3, thereby preventing the glue from flowing back. When pressed down, the spring 6 drives the sealing ball 7 to block the suction tube 8, thereby pushing open the sealing ball 9 and flowing out from the glue outlet tube 12.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
