[0003] An AB glue applicator is a device specifically used for precisely mixing and coating two-component AB glue, and is widely used in industrial production and some specific manual manufacturing fields. The AB glue applicator stores component A glue and component B glue in two independent glue barrels respectively, uses high-precision metering pumps to extract the two glue liquids according to a set ratio, then fully mixes them evenly in a mixing tube, and finally evenly coats the mixed AB glue on the surface of the object to be bonded through a coating head.

[0042] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can still be made. These all fall within the protection scope of the present invention.

[0043] Such as Figure 1-7As shown in the figure, a new type of two-component reciprocating metering cylinder provided by the present invention includes: a first stroke cylinder 1, a second stroke cylinder 2, and an inlet and outlet assembly. The first stroke cylinder 1 and the second stroke cylinder 2 perform synchronous reciprocating motions in opposite directions; the output ends of the first stroke cylinder 1 and the second stroke cylinder 2 are communicated with the internal channels of the inlet and outlet assembly. On the inlet and outlet assembly, inlet and outlet switch control cylinders are correspondingly arranged. The inlet switch control cylinder and the outlet switch control cylinder of the same stroke cylinder are not opened or closed simultaneously. The two inlet switch control cylinders are not opened or closed simultaneously, and the two outlet switch control cylinders are not opened or closed simultaneously; both the first stroke cylinder 1 and the second stroke cylinder 2 include an A-component cylinder block and a B-component cylinder block. The A-component cylinder block and the B-component cylinder block perform synchronous reciprocating motions in the same direction. The volume cavity ratio of the A-component cylinder block and the B-component cylinder block is consistent with the glue mixing volume ratio. The inlet and outlet assembly includes an inlet and outlet assembly cover plate 21. Corresponding to the inlet and outlet assembly cover plate 21 are the total inlets and outlets of the A-component and the total inlets and outlets of the B-component.

[0044] This application uses single-stroke synchronous control to move the A and B component glues, and the volume cavity ratio of A and B is consistent with the glue mixing volume ratio, making the mixing ratio of A and B glues more accurate. The design of mutual switching between two strokes enables continuous outflow of the glue. A single cylinder simultaneously controls the opening and closing of the inlets and outlets of A and B, making the mutual switching more sensitive and accurate.

[0045] Above the first stroke cylinder 1, there is a first stroke cylinder sensor 3, and a magnetic device is arranged inside the piston of the first stroke cylinder 1.

[0046] Above the second stroke cylinder 2, there is a second stroke cylinder sensor 4, and a magnetic device is arranged inside the piston of the second stroke cylinder 2.

[0047] When the first stroke cylinder 1 is ventilated, the magnetic field inside the cylinder piston moves to the left until the pneumatic magnetic induction switch of the first stroke cylinder sensor 3 is triggered to control the air path to switch to the second stroke cylinder 2 for ventilation. At the same time, the first stroke A-component cylinder block 12 and the first stroke B-component cylinder block 9 quickly flush the glue, driving the piston of the first stroke cylinder 1 to move to the right until the end. The magnetic field inside the piston of the second stroke cylinder 2 moves to the left. When the pneumatic magnetic induction switch air path of the second stroke cylinder sensor 4 is triggered, the air path switches back to the original path. The second stroke A-component cylinder block 16 and the second stroke B-component cylinder block 14 quickly flush the glue, driving the piston of the second stroke cylinder 2 to move to the right until the end. The above movements are continuously cycled.

[0048] On the inlet and outlet assembly, there are a first stroke outlet switch control cylinder 5 and a first stroke inlet switch control cylinder 7 corresponding to the first stroke cylinder 1. When the first stroke cylinder 1 approaches the inlet and outlet assembly, the first stroke outlet switch control cylinder 5 opens the outlet, and the first stroke inlet switch control cylinder 7 closes the inlet.

[0049] The import and export assembly is provided with a second stroke outlet switch control cylinder 6 and a second stroke inlet switch control cylinder 8 corresponding to the second stroke cylinder 2. When the second stroke cylinder 2 approaches the import and export assembly, the second stroke outlet switch control cylinder 6 opens the outlet, and the second stroke inlet switch control cylinder 8 closes the inlet.

[0050] When the first stroke cylinder 1 approaches the import and export assembly, the second stroke outlet switch control cylinder 6 closes its corresponding outlet, and the second stroke inlet switch control cylinder 8 opens its corresponding inlet.

[0051] The first stroke cylinder 1 includes detachably installed: a first stroke B-component cylinder block 9, a first stroke B-component piston 10, a first stroke A-component piston 11, and a first stroke A-component cylinder block 12. The internal cavity of the first stroke B-component cylinder block 9 communicates with the B-component import and export, and the internal cavity of the first stroke A-component cylinder block 12 communicates with the A-component import and export.

[0052] The second stroke cylinder 2 includes detachably installed: a second stroke B-component piston 13, a second stroke B-component cylinder block 14, a second stroke A-component piston 15, and a second stroke A-component cylinder block 16. The internal cavity of the second stroke B-component cylinder block 14 communicates with the B-component import and export, and the internal cavity of the second stroke A-component cylinder block 16 communicates with the A-component import and export. In practical applications, when encountering different glue ratios, components can be directly replaced according to the glue ratio.

[0053] The import and export assembly cover plate 21 is provided with an A-component total outlet 17, an A-component total inlet 18, a B-component total outlet 19, and a B-component total inlet 20, and a flow channel is correspondingly arranged on the import and export assembly cover plate 21.

[0054] In this application, the first-stroke cylinder 1 and the second-stroke cylinder 2 perform synchronous reciprocating left and right movements to simultaneously deliver two-component glue. When the first-stroke cylinder 1 moves to the left, the first-stroke inlet switch control cylinder 7 is closed, and the first-stroke outlet switch control cylinder 5 is opened to deliver the glue in the first-stroke A-component cylinder body 12 and the first-stroke B-component cylinder body 9. At the same time, the second-stroke inlet switch control cylinder 8 is opened, and the second-stroke outlet switch control cylinder 6 is closed, and glue replenishment starts in the second-stroke A-component cylinder body 16 and the second-stroke B-component cylinder body 14, and the second-stroke cylinder 2 moves to the right. When the first-stroke cylinder 1 triggers the signal of the first-stroke cylinder sensor 3 and switches to the second-stroke cylinder 2 moving to the left, the second-stroke inlet switch control cylinder 8 is closed, and the second-stroke outlet switch control cylinder 6 is opened to deliver the glue in the cavities of the second-stroke A-component cylinder body 16 and the second-stroke B-component cylinder body 14. At the same time, the first-stroke inlet switch control cylinder 7 is opened, and the first-stroke outlet switch control cylinder 5 is closed, and glue replenishment starts in the first-stroke A-component cylinder body 12 and the first-stroke B-component cylinder body 9, and the first-stroke cylinder 1 moves to the right. Wait for the second-stroke cylinder 2 to trigger the signal of the second-stroke cylinder sensor 4 and then switch; cycle the above movements, and the glue continuously outputs from the outlet. By using the channel structure designed inside the inlet and outlet assembly cover plate 21, the original multiple inlets and outlets are combined into the existing four inlets and outlets.

[0055] In this application, by adopting the design of standard cylinders, the control requires no power supply, is fully pneumatic control, has a simpler structure, is more concise and convenient for maintenance, and has a lower cost.

[0056] In this application, by adopting the design of controlling the cyclic movement of the first-stroke cylinder 1 and the second-stroke cylinder 2, the glue in the first-stroke and second-stroke cylinder bodies is stably delivered, achieving a continuous and uninterrupted output effect.

[0057] In this application, through the mechanism design of connecting the cylinder rod of the first-stroke cylinder 1 to the first-stroke A-component piston rod 11 and the first-stroke B-component piston rod 10, the A and B component pistons move synchronously, solving the problem of asynchronous glue output of the A and B components and achieving the effect of precise mixing ratio accuracy of the A and B component glues.

[0058] In this application, by using the cylinder rod of the inlet and outlet switch control cylinder to connect the switch rod and the ball to synchronously control the A and B component outlet switches, the problem of inconsistent A and B component outlet switches is solved, achieving the effect of simultaneous glue output.

[0059] Through the structural design of the internal processing channels of the import and export assembly cover plate 21 in this application, the A-component inlets of the first and second strokes are combined, the A-component outlets of the first and second strokes are combined, the B-component inlets of the first and second strokes are combined, and the B-component outlets of the first and second strokes are combined, solving the problems of complex and cumbersome import and export connections and avoiding import and export interference. The appearance becomes simple and beautiful.
