Technical Field

[0001] The present application relates to the field of glue dispensing equipment, and in particular to a high-precision glue dispensing equipment. Background Art

[0002] Bonding is a very common way to fix parts in industrial production. There are many types of adhesives on the market, including UV glue, thermosetting glue, etc.

[0003] In the production process of the beam splitter, the beam splitter needs to be placed in a box body, and then glue is applied around the box body, and a cover is placed on the box body to make the cover and the box body sealed. Usually, the operator applies glue around the box body with a handheld glue dispenser.

[0004] However, when operators manually dispense glue, they cannot precisely control the amount of glue squeezed out during dispensing, often resulting in too much or too little glue. Utility Model Content

[0005] In order to achieve accurate control of glue flowing out of a glue dispenser, the present application provides a high-precision glue dispensing device.

[0006] The high-precision dispensing equipment provided in this application adopts the following technical solution:

[0007] A high-precision glue dispensing device comprises a rubber hose, one end of which is connected to an air pump, a piston block is arranged inside the rubber hose, and the piston block is in sliding contact with the inner wall of the rubber hose.

[0008] By adopting the above technical solution, when it is necessary to inject glue into a certain place, the glue is first placed inside the hose, and then the air pump is started. The air pump drives the piston block inside the hose to move. During the movement, the piston block squeezes the glue inside the hose, so that the glue can flow out from the end of the hose. By driving the piston block to move by the air pump, the quantitative outflow of the glue inside the hose can be controlled, thereby reducing the phenomenon that the amount of glue flowing out of the hose is unstable, resulting in too much or too little glue affecting subsequent use.

[0009] Optionally, one end of the rubber hose away from the air pump is connected to a needle.

[0010] By adopting the above technical solution and providing a needle, the phenomenon that the glue flowing out of the end of the hose is difficult to flow to the appropriate position for bonding can be reduced.

[0011] Optionally, one end of the needle near the rubber tube is fixedly connected to a needle sleeve, one end of the rubber tube near the needle is fixedly connected to a connecting tube, and the needle sleeve is threadedly connected to the connecting tube.

[0012] By adopting the above technical solution and setting a threaded connection between the needle and the hose, when the pillow becomes clogged after long-term use, the needle can be removed from the hose by rotating the needle sleeve for replacement, thereby reducing the trouble of replacing the needle when the needle is clogged.

[0013] Optionally, the side wall of the hose is transparent and has scales.

[0014] By adopting the above technical solution and setting a scale on the side wall of the hose, the staff can monitor the amount of glue inside the hose during use, which makes it convenient for the staff to replenish the glue inside the hose according to the remaining amount of glue inside the hose.

[0015] Optionally, the hose is provided with a sealing member connecting the inside of the hose with the outside.

[0016] By adopting the above technical solution and providing a sealing member, it is convenient for workers to add glue to the inside of the hose.

[0017] Optionally, the closure member is an end cap, which is located at an end of the hose away from the needle and is threadedly connected to the end of the hose.

[0018] By adopting the above technical solution, when it is necessary to add glue to the inside of the hose, the glue can be injected into the hose by opening the end cover and taking the piston block out from the inside of the hose.

[0019] Optionally, an opening is provided on the side wall of the hose, the closure member includes a rotating plate located at the opening, a plurality of abutment blocks rotatably connected to the outer wall of the hose that can abut against the rotating plate, and a torsion spring is connected between each abutment block and the outer wall of the hose.

[0020] By adopting the above technical solution, when it is necessary to inject glue into the hose, the stop block is rotated, and then the rotating plate is rotated to leak the opening on the side wall of the hose, so that glue can be injected into the hose.

[0021] Optionally, a sealing ring is fixedly connected to one side of the rotating plate close to the inside of the hose.

[0022] By adopting the above technical solution and providing a sealing ring, the phenomenon of glue leaking out of the opening of the side wall of the hose during actual use is reduced.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] By arranging a piston block inside the hose and connecting an air pump to drive the piston block inside the hose to move, it is reduced that the worker has difficulty in controlling the amount of glue flowing out of the hose during use;

[0025] By providing a needle at the end of the hose, the phenomenon that the glue flowing out of the hose is difficult to accurately flow to the position where the glue is required to be placed during actual use can be reduced;

[0026] By providing the sealing piece, the trouble of injecting glue into the rubber hose during actual use can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0031] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.

[0032] The embodiment of the present application discloses a high-precision glue dispensing device. Example 1

[0033] Reference Figure 1 and Figure 2 A high-precision dispensing device includes a hose 1, one end of the hose 1 is connected to an air pipe 2, and the end of the air pipe 2 away from the hose 1 is connected to an air pump 3. A piston block 11 is provided inside the hose 1, and the side wall of the piston block 11 is in sliding contact with the inner wall of the hose 1.

[0034] The end of the hose 1 away from the trachea 2 is fixedly connected to the connecting tube 12. The connecting tube 12 is connected to the needle 4, and the end of the needle close to the connecting tube 12 is fixedly connected to the needle sleeve 41. The inner wall of the needle sleeve 41 and the outer wall of the connecting tube 12 are provided with corresponding threads, and the needle sleeve 41 and the connecting tube 12 are threadedly connected.

[0035] When it is necessary to inject glue into a certain place, the glue is first injected into the side of the piston block 11 inside the hose 1 close to the needle 4, and then the air pump 3 is started. By adjusting the amount of gas entering the hose 1 by the air pump 3, the moving distance of the piston block 11 inside the hose 1 can be controlled, thereby achieving accurate control of the glue flowing out of the needle 4 connected to one end of the hose 1.

[0036] The glue inside the hose 1 is squeezed by using the air pump 3 to drive the piston block 11 to move inside the hose 1, so that the glue inside the hose 1 can flow out from the needle 4 at the end, thereby accurately controlling the amount of glue flowing out of the needle 4 and making it convenient for the staff to control the process of glue flowing out of the needle 4.

[0037] The side wall of the hose 1 is transparent, and scale values ​​are provided on the outer wall of the hose 1 .

[0038] By providing scales on the outer wall of the hose 1 , the staff can observe the amount of glue used inside the hose 1 through the scales provided on the outer wall of the hose 1 during use.

[0039] The hose 1 is connected with a sealing member 5, and the sealing member 5 is used to connect and block the connection between the end of the hose 1 and the outside world.

[0040] Since the sealing member 5 is provided, the staff can inject glue into the rubber hose 1 by opening the sealing member 5 , thereby facilitating the process of the staff replenishing glue into the rubber hose 1 .

[0041] The closure member 5 includes an end cap 51, the inner wall of which is provided with threads, an opening is provided at one end of the hose 1 close to the air pipe 2, and threads corresponding to the inner wall of the end cap 51 are provided on the outer wall of the hose 1 close to the air pipe 2, and the end cap 51 is threadedly connected to the end of the hose 1. The air pipe 2 passes through the end cap 51 and is fixedly connected to the end cap 51.

[0042] When glue needs to be injected into the hose 1, open the end cover 51, move the piston block 11 out of the end cover 51, and then inject glue into the hose 1. After the glue injection is completed, place the piston block 11 into the hose 1, and then tighten the end cover 51.

[0043] The implementation principle of Example 1 is: when glue needs to be injected into a certain place, first open the end cover 51 and move the piston block 11 out of the hose 1, then inject glue into the hose 1, put the piston block 11 into the hose 1 and tighten the end cover 51.

[0044] Then, the needle 4 is pointed toward the place where glue needs to be injected, and then the air pump 3 is adjusted to allow a certain amount of gas to enter the hose 1 and drive the piston block 11 inside the hose 1 to move to an appropriate position. Then, the piston block 11 drives the glue inside the hose 1 to move, so that the certain amount of glue moves out of the hose 1, thereby realizing the process of injecting a certain amount of glue into a specific position. Example 2

[0045] Reference Figure 3 The embodiment of the present application is different from the embodiment 1 in that an opening is provided on the side wall of the hose 1 and penetrates the side wall of the hose 1. The closure member 5 includes a rotating plate 52 located at the opening and rotatably connected to the outer wall of the hose 1, a baffle 521 is fixedly connected to the side of the rotating plate 52 close to the opening of the side wall of the hose 1, a sealing ring 522 is fixedly connected to the side wall of the baffle 521, and when the rotating plate 52 is in contact with the outer wall of the hose 1, the baffle 521 and the sealing ring 522 can both move to the inside of the opening and make the side of the sealing ring 522 away from the baffle 521 abut against the side wall of the hose 1 at the opening to seal the opening.

[0046] A stopper 53 is provided on both sides of the rotating plate 52 away from the end of the rotating connection with the hose 1, and there is a gap between the stopper 53 and the outer wall of the hose 1 that can accommodate the rotating plate 52. The two stoppers 53 are arranged opposite to each other, and the sides of the opposite ends of the two stoppers 53 away from the outer wall of the hose 1 are arranged as inclined surfaces, and the two inclined surfaces are arranged in a direction gradually approaching each other from the side away from the outer wall of the hose 1 to the side close to the outer wall of the hose 1.

[0047] The ends of the two stoppers 53 that are away from each other are penetrated and rotatably connected with a connecting rod 531, and one end of each connecting rod 531 that penetrates the stopper 53 is fixedly connected to the outer wall of the hose 1. A torsion spring 532 is fixedly connected between each connecting rod 531 and the stopper 53 to which it is connected.

[0048] When it is necessary to inject glue into the rubber tube 1, the two abutting blocks 53 are rotated in the direction away from each other, and then the rotating plate 52 is rotated to the side away from the outer wall of the rubber tube 1, so that the opening on the outer wall of the rubber tube 1 can connect the inside of the rubber tube 1 with the outside, and then the glue is injected into the rubber tube 1 on the side of the piston block 11 away from the needle 4. The rotating plate 52 is rotated so that the baffle 521 and the sealing ring 522 can block the opening of the outer wall of the rubber tube 1, and then the abutting block 53 is driven by the torsion spring 532 to move to the side of the rotating plate 52 away from the outer wall of the rubber tube 1 and abut against the rubber tube 1, thereby realizing the process of injecting glue into the rubber tube 1.

[0049] The implementation principle of Example 2 is as follows: the opening on the outer wall of the hose 1 can be leaked out by rotating the rotating plate 52, so that glue can be injected into the inside of the hose 1 through the opening on the outer wall of the hose 1, and then the rotating plate 52 is rotated to block the opening on the outer wall of the hose 1, and the position of the rotating plate 52 is restricted by the abutment block 53 abutting against the rotating plate 52, thereby completing the process of injecting glue into the inside of the hose 1.

[0050] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
