Description

Technical Field

[0001] The utility model relates to a device for connecting products made of different materials, in particular to a gluing device. Background Art

[0002] The bonding and gluing equipment for composite materials and metal materials adopts manual screw extrusion and piston cylinder extrusion solutions. This solution has the following technical problems:

[0003] First, the temperature of the rubber material in the storage barrel will drop and its fluidity will deteriorate;

[0004] Second, the glue injection process is a one-way flow and cannot be exhausted in time;

[0005] Third, the amount of glue injected cannot be measured and the injection action cannot be automatically controlled;

[0006] Fourth, the glue contains bubbles, which will cause bubbles to remain inside the glue after curing, affecting the bonding strength;

[0007] Fifth, the barrel and silicone tube are inconvenient to clean. Utility Model Content

[0008] The technical problem solved by the utility model is that the manual screw extrusion type and the piston cylinder extrusion type scheme are used to bond and glue composite materials and metal materials, but the barrel and the silicone material tube are inconvenient to clean.

[0009] In order to solve the above technical problems, the utility model provides the following technical solutions: a gluing device for bonding composite materials and metal materials, including a barrel, a material pipe inserted into the barrel, and a material driving pump used in conjunction with the material pipe. The material pipe is connected to the mold, and the barrel is placed in an outer shell. The top of the outer shell is open, and the top of the outer shell is equipped with a cover plate. The cover plate includes a cover plate body and a rubber pad fixedly connected to the cover plate body. The rubber pad is frustum-shaped, the rubber pad covers the top of the barrel and the cover plate body covers the top of the outer shell. A fastening bolt is connected between the cover plate body and the outer shell. The material pipe passes through the cover plate and penetrates into the bottom of the barrel. A telescopic spring is provided at the bottom of the outer shell.

[0010] According to the above technical solution, the barrel is placed into the housing from top to bottom. The bottom of the barrel is supported by a telescopic spring, and the rubber pad of the cover presses down on the barrel to seal it. Under the dual pressure of the rubber pad and the telescopic spring, the barrel's sealing state can be effectively maintained.

[0011] Since the rubber pad is in the shape of a truncated cone, when the rubber pad presses down the barrel, the top edge of the barrel exerts a radial force on the rubber pad, causing the rubber pad to tighten the barrel, achieving a close fit between the barrel and the rubber pad, and the sealing state of the barrel can be effectively maintained.

[0012] When the barrel needs to be cleaned, loosen the fastening bolts, open the cover, and take out the barrel from the shell. The barrel can be cleaned effectively and conveniently.

[0013] The outer wall of the barrel is provided with a lifting ring near the top of the barrel. A worker can hook the lifting ring with a hook and lift the barrel from the shell.

[0014] The cover plate body features an axial projection with an outer diameter equal to the inner diameter of the outer shell. When the barrel is placed in the outer shell, the rubber pad engages with the top opening of the barrel, while the axial projection fits within the inner ring of the outer shell. Because the rubber pad is frustoconical, the barrel and outer shell naturally align when the cover plate presses down on the barrel, facilitating subsequent temperature monitoring by a temperature sensor.

[0015] A temperature sensor is provided on the inner wall of the outer shell, an insulating seat is provided at the inner bottom of the outer shell, a telescopic spring is located on the insulating seat, and the telescopic spring is connected to a heating wire. There is a gap between the temperature sensor and the outer wall of the barrel. When the telescopic spring is energized, it becomes a heating conductor, which heats the barrel. The heat is transferred quickly in the barrel, and the temperature of the barrel's side walls rises quickly. However, the heat is transferred slowly from the barrel to the material inside the barrel. If the temperature sensor is in direct contact with the barrel's side walls, it will cause a misjudgment of the temperature of the material in the barrel. Therefore, the utility model installs the temperature sensor on the inner wall of the outer shell with a gap between it and the outer wall of the barrel. The speed at which the barrel's temperature is transferred to the material inside is equivalent to the speed at which it is transferred to the temperature sensor outside. The temperature sensor can accurately monitor the temperature of the material inside the barrel.

[0016] Alternatively, a temperature sensor is electrically connected to a temperature controller, which is in turn electrically connected to a switch on the heating wire. Workers can set the temperature using the temperature controller, and the temperature sensor provides real-time feedback to the controller. When the set temperature is reached, the controller switches off the heating wire, stopping the retractable spring from heating. If the temperature falls below the set temperature, the controller switches off the heating wire, heating the retractable spring. This maintains a constant temperature in the barrel, enhancing the fluidity of the material (i.e., the rubber compound).

[0017] A vacuum tube and an air pipe are inserted into the barrel. The vacuum tube is connected to a vacuum pump, and an air filter is installed on the air pipe. The vacuum pump evacuates the sealed barrel through the vacuum tube. At the same time, external gas enters the barrel through the air pipe. In this way, the bubbles in the material can be removed by the vacuum pump. Ball valves are installed on the vacuum tube and the air pipe to control the air output and air intake of the barrel, which is conducive to the effective removal of bubbles in the material. There are no bubbles inside the material (i.e. rubber material), and there are no bubble defects inside after curing.

[0018] As an option, the material driving pump adopts a peristaltic pump and a ball valve is provided on the material pipe, so that the feeding amount of the material to the mold can be controlled.

[0019] Compared with the prior art, the present invention has the following technical effects:

[0020] First, the temperature of the rubber compound is controllable and has strong fluidity;

[0021] Second, the injection process is simple, the glue material is controllable, and the product quality is improved after injection;

[0022] Third, there are no bubbles inside the rubber compound, and there are no bubble defects inside after curing;

[0023] Fourth, it reduces the cleaning intensity of employees and reduces the loss of barrels and tubes;

[0024] Fifth, the product has strong bonding strength after glue injection, and the tensile data is significantly improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] refer to Figure 1 、 Figure 2A gluing device for bonding composite materials and metal materials includes a barrel 10, a material pipe 11 inserted into the barrel, and a material driving pump used in conjunction with the material pipe. The material pipe is connected to a mold 12. The barrel is placed in an outer shell 20. The top of the outer shell is open. A cover plate 30 is provided on the top of the outer shell. The cover plate includes a cover plate body and a rubber pad 32 fixedly connected to the cover plate body. The rubber pad is frustum-shaped. The rubber pad covers the top of the barrel and the cover plate body covers the top of the outer shell. A fastening bolt 34 is connected between the cover plate body and the outer shell. The material pipe passes through the cover plate and penetrates into the bottom of the barrel. A telescopic spring 21 is provided at the bottom of the outer shell.

[0034] A hanging ring 13 is provided on the outer side wall of the barrel 10, and the hanging ring is close to the top of the barrel.

[0035] The cover body is provided with an axial protrusion 33 , the outer diameter of which is equal to the inner diameter of the housing 20 .

[0036] A temperature sensor 22 is provided on the inner wall of the housing 20 , an insulating seat 23 is provided on the inner bottom of the housing, a telescopic spring 21 is located on the insulating seat, and the telescopic spring is connected to a heating wire 24 .

[0037] A vacuum tube 41 and an air pipe 42 are inserted into the barrel 10 . The vacuum tube is connected to a vacuum pump 40 . An air filter element 43 is provided on the air pipe.

[0038] The material driving pump adopts a peristaltic pump 14.

[0039] The barrel 10 is placed from top to bottom into the housing 20, with the bottom of the barrel supported by the telescopic spring 21. The rubber pad 32 fits into the top opening of the barrel 10, while the axial protrusion 33 fits into the inner ring of the top of the housing 20. Because the rubber pad 32 is truncated cone-shaped, it can naturally align the barrel 10 with the housing 20 when the cover plate 30 presses down on the barrel 10.

[0040] The rubber pad 32 of the cover plate presses down the barrel 10 to seal the barrel. Under the dual pressure of the rubber pad 32 and the telescopic spring 21, the sealed state of the barrel 10 can be effectively maintained.

[0041] Since the rubber pad 32 is in the shape of a truncated cone, when the rubber pad 32 presses down the barrel 10, the top edge of the barrel 10 exerts a radial force on the rubber pad 32, causing the rubber pad to tighten the material pipe 11, the vacuum pipe 41, and the air pipe 42, thereby achieving a close fit between the material pipe, the vacuum pipe, the air pipe and the rubber pad, and the sealing state of the barrel 10 can be effectively maintained.

[0042] Temperature sensor 22 is electrically connected to a temperature controller, which is in turn electrically connected to a switch on heating wire 24. Workers can set the temperature using the temperature controller, and the temperature sensor provides real-time feedback to the temperature controller. When the set temperature is reached, the temperature controller switches off the switch on the heating wire, stopping heating of telescopic spring 21. When the monitored temperature falls below the set temperature, the temperature controller switches off the switch on heating wire 24, heating telescopic spring 21. This maintains a constant temperature for the material in barrel 10, enhancing the fluidity of the material (i.e., the rubber compound).

[0043] A vacuum pump 40 evacuates the sealed barrel 10 via a vacuum line 41. Simultaneously, external air enters the barrel 10 via an air line 42, removing any bubbles in the material. Ball valves 44 are installed on both the vacuum line 41 and the air line 42 to control the air flow into and out of the barrel 10.

[0044] A ball valve is provided on the material pipe 11 , and the material in the barrel 10 is fed to the mold 12 under the drive of the peristaltic pump 14 , and the feeding amount is controllable.

[0045] When the barrel 10 needs to be cleaned, the fastening bolts 34 are loosened, the cover plate 30 is opened, and the worker can hook the lifting ring 13 with a hook to lift the barrel 10 from the housing 20. The barrel 10 can be cleaned effectively and conveniently.

[0046] The above content is only a preferred embodiment of the present invention. For ordinary technicians in this field, according to the concept of the present invention, there may be changes in the specific implementation method and application scope. The content of this specification should not be understood as limiting the present invention.
