Description

Technical Field

[0001] This application relates to the field of injection equipment technology, and in particular to an injection device. Background Technology

[0002] Currently, composite materials are increasingly widely used in aerospace, automotive, wind power and other fields, and the preparation process of composite materials is a key link.

[0003] In the existing system, driver's cab hoods are mostly prepared using processes such as hand lay-up and injection. However, traditional resin injection processes rely heavily on manual operation, such as manually mixing resin, manually stirring resin with a hand-held stirring rod, and manually holding the resin guide tube. This results in problems such as inaccurate resin ratio, uneven mixing, low injection efficiency, and high risk of air leakage. At the same time, human factors can easily lead to unstable product quality.

[0004] Therefore, it is necessary for those skilled in the art to develop a filling device that has precise resin proportioning, uniform mixing, high filling efficiency, and stable product quality, in order to improve the accuracy and production efficiency of composite material filling processes. Utility Model Content

[0005] The purpose of this application is to provide a filling device that solves the problems of inaccurate resin ratio, uneven mixing, low filling efficiency, and unstable product quality.

[0006] To achieve the above objectives, this application provides an infusion apparatus, comprising:

[0008] A stirring mechanism is used to stir the resin and curing agent in the resin tank;

[0009] The degassing mechanism includes a barrel body and a barrel lid. The barrel body is used to contain the resin barrel. The barrel lid is sealed to the barrel body. The barrel lid is connected to a vacuum pump. The vacuum pump draws a vacuum to create a negative pressure inside the barrel, so as to expel the air bubbles inside the resin barrel.

[0010] A clamping mechanism includes a clamping assembly and a support bracket, the support bracket being rotatably disposed on the clamping assembly and used to support a resin bucket;

[0011] The injection pipeline control mechanism is used to control the opening and closing of the injection pipeline connecting the mold and the resin tank, so as to control the resin in the resin tank to be introduced into the mold.

[0012] In some embodiments, both the resin storage tank and the curing agent storage tank are connected to a weighing sensor, and both the outlet end of the resin storage tank and the outlet end of the curing agent storage tank are connected to a metering pump. The metering pump is used to control a fixed amount of resin and curing agent poured into the resin tank.

[0013] In some embodiments, a temperature control system is provided on the outside of the resin storage tank and the curing agent storage tank, the temperature control system being used to control the temperature of the resin storage tank and the curing agent storage tank below 60 degrees Celsius.

[0014] In some embodiments, the filling device further includes an air extraction pipeline control mechanism, which is used to control the opening and closing of the air extraction pipeline connecting the mold and the air extraction pump. After the air extraction pipeline control mechanism is opened to make the negative pressure value inside the mold reach a specified value, the filling pipeline control mechanism is opened to control the resin in the resin tank to be introduced into the mold.

[0015] In some embodiments, the clamping assembly includes symmetrically arranged clamps, and the support bracket is rotatably connected to the clamps via bearings. The rotation angle of the support bracket is adjustable from -45 degrees to 45 degrees and controlled by a servo motor.

[0016] In some embodiments, the clamping mechanism further includes:

[0017] The movable base plate is equipped with steering wheels at its bottom;

[0018] The robotic arm is mounted on a movable base plate and located on one side of the gripping assembly;

[0019] The positioning plate is installed on the robotic arm and is equipped with a fixing component, which is used to fix the filling pipeline connected to the resin tank.

[0020] In some embodiments, the clamping mechanism further includes:

[0021] A weight sensor, located on the support frame, is used to detect the weight of the resin bucket;

[0022] A buzzer alarm, mounted on the support frame and connected in communication with a weight sensor, is used to trigger the buzzer alarm when the weight of the resin bucket falls below a threshold.

[0023] In some embodiments, the stirring mechanism includes:

[0024] The support base includes a base body and two clamps, which are movably connected to the base body. The spacing between the two clamps is adapted to the diameter of the resin bucket to hold the resin bucket.

[0025] The adjustable stirring paddle is used to stir the resin and curing agent in the resin tank.

[0026] The drive assembly, connected to the stirring paddle, is used to drive the stirring paddle to rotate.

[0027] In some embodiments, the injection pipeline control mechanism includes a control valve and a flow sensor. The control valve is installed at the outlet of the injection pipeline connected to the resin tank, and the flow sensor is used to monitor the resin flow rate into the mold in real time.

[0028] In some embodiments, the barrel is provided with an observation window for observing the degassing process inside the barrel;

[0029] A pressure sensor is installed on the lid of the container. The pressure sensor is used to detect the negative pressure state inside the container and transmits the detection signal to the control unit. The control unit controls the start and stop of the vacuum pump according to the detection signal.

[0030] Compared to the aforementioned background technology, the filling device provided in this application includes a mixing mechanism, a stirring mechanism, a degassing mechanism, a clamping mechanism, and a filling pipeline control mechanism. The mixing mechanism includes a resin storage tank and a curing agent storage tank, which are used to pour fixed amounts of resin and curing agent into a resin tank, respectively. The stirring mechanism is used to stir the resin and curing agent in the resin tank. The degassing mechanism includes a tank body and a lid. The tank body is used to contain the resin tank, and the lid is sealed to the tank body. The lid is connected to a vacuum pump, which creates a negative pressure inside the tank to expel air bubbles. The clamping mechanism includes a clamping assembly and a support frame. The support frame is rotatably mounted on the clamping assembly and is used to support the resin tank. The filling pipeline control mechanism controls the opening and closing of the filling pipeline connecting the mold and the resin tank to control the introduction of resin from the resin tank into the mold.

[0031] In this setup, the resin, prepared by the mixing mechanism, is sequentially stirred and degassed by the stirring and degassing mechanisms. At the start of pouring, the resin tank is held and fixed by a clamping mechanism, and the pouring pipeline control mechanism controls the opening and closing of the pouring pipeline connecting the mold and the resin tank. Specifically, before pouring begins, the mixing mechanism pours a fixed amount of resin and hardener into the resin tank according to the mixing instructions. The resin tank is then transferred to the stirring mechanism, where the resin and hardener are stirred using a pre-set stirring speed and time. Stirring stops when the time is up, and the resin tank is then transferred to the degassing mechanism for degassing under vacuum. After degassing, the resin tank is held by the clamping mechanism. Once everything is ready, the pouring pipeline control mechanism is opened, allowing the resin to be evenly introduced into the mold. This pouring device, with its above-described configuration, achieves precise resin mixing, uniform stirring, high pouring efficiency, and stable product quality, solving the problems of inaccurate resin mixing, uneven stirring, low pouring efficiency, and unstable product quality inherent in traditional manual operations.

[0054] It should be noted that the directional terms such as "upper end," "lower end," "left side," and "right side" mentioned below are defined based on the accompanying drawings in the instruction manual.

[0056] The infusion device provided in this application includes a mixing mechanism 10, a stirring mechanism 20, a defoaming mechanism 30, a clamping mechanism 40, and an infusion pipeline control mechanism 50.

[0057] The mixing mechanism 10 includes a resin storage tank 11 and a curing agent storage tank 12, which are used to pour fixed amounts of resin and curing agent into the resin tank 70, respectively.

[0058] The stirring mechanism 20 is used to stir the resin and curing agent in the resin tank 70.

[0059] The degassing mechanism 30 includes a barrel body 31 and a barrel cover 32. The barrel body 31 is used to contain the resin barrel 70. The barrel cover 32 is sealed to the barrel body 31. The barrel cover 32 is connected to a vacuum pump. The vacuum pump draws a vacuum to create a negative pressure state inside the barrel body 31, so as to expel the air bubbles inside the resin barrel 70.

[0060] The clamping mechanism 40 includes a clamping assembly 41 and a support frame 42. The support frame 42 is rotatably disposed on the clamping assembly 41 and is used to support the resin bucket 70.

[0061] The injection pipeline control mechanism 50 is used to control the opening and closing of the injection pipeline 80 connecting the mold 90 and the resin tank 70, so as to control the resin in the resin tank 70 to be introduced into the mold 90.

[0062] With this setup, the resin prepared by the mixing mechanism 10 is sequentially mixed and degassed by the stirring mechanism 20 and the degassing mechanism 30. At the start of the filling process, the resin tank 70 is clamped and fixed by the clamping mechanism 40, and the filling pipeline control mechanism 50 controls the opening or closing of the filling pipeline 80 connecting the mold 90 and the resin tank 70.

[0063] Specifically, before the infusion begins, the mixing mechanism 10 pours a fixed amount of resin and curing agent into the resin tank 70 according to the mixing instructions. Then, the resin tank 70 is transferred to the stirring mechanism 20, where the resin and curing agent in the resin tank 70 are stirred by the stirring mechanism 20, which has been pre-set with a stirring speed and time. Stirring stops when the time is up, and then the resin tank 70 is transferred to the degassing mechanism 30 for degassing under vacuum. After the degassing is complete, the resin tank 70 is clamped by the clamping mechanism 40. Once everything is ready, the infusion pipeline control mechanism 50 is opened to allow the resin to be evenly introduced into the mold 90.

[0064] The injection device with the above-mentioned setup has accurate resin ratio, uniform mixing, high injection efficiency, and stable product quality, solving the problems of inaccurate resin ratio, uneven mixing, low injection efficiency, and unstable product quality that exist in traditional manual operation.

[0065] In some embodiments, the capacity of both the resin storage tank 11 and the curing agent storage tank 12 is 40-60 kg. Both the resin storage tank 11 and the curing agent storage tank 12 are connected to a weighing sensor. The resin storage tank 11 and the curing agent storage tank 12 can accurately inject resin and curing agent according to a preset weight.

[0066] To facilitate precise injection of resin and curing agent, metering pumps are connected to the outlet ends of both the resin storage tank 11 and the curing agent storage tank 12. The metering pumps are used to control the fixed amount of resin and curing agent poured into the resin tank 70.

[0067] In some embodiments, a temperature control system is provided on the outside of the resin storage tank 11 and the curing agent storage tank 12, and the temperature control system is used to control the temperature of the resin storage tank 11 and the curing agent storage tank 12 to below 60 degrees Celsius.

[0068] In this way, by setting up a temperature control system, the storage tank can be heated from room temperature to 60°C, ensuring that the temperature of the resin and curing agent remains stable during each injection.

[0069] In some embodiments, the filling device further includes a vacuum line control mechanism 60, which controls the opening and closing of the vacuum line 100 connecting the mold 90 and the vacuum pump 110. After the vacuum line control mechanism 60 is opened to make the negative pressure value inside the mold 90 reach a specified value, the filling line control mechanism 50 is opened to control the resin in the resin tank 70 to be introduced into the mold 90. Of course, the vacuum line control mechanism 60 can be a vacuum line solenoid valve control mechanism.

[0070] For example, once everything is ready, the solenoid valve control mechanism of the air extraction pipeline is opened to bring the negative pressure inside the mold 90 to below the specified value of -0.094MPa. Then, according to the resin flow pipeline layout of the mold 90, the injection pipeline control mechanism 50 is opened in sequence to allow the resin to be evenly introduced into the mold 90. After the injection is completed, the injection pipeline control mechanism 50 is closed, and the composite material product in the mold cavity is left to stand and cure naturally.

[0071] In some embodiments, the clamping assembly 41 includes symmetrically arranged clamps, the inner side of which is covered with an anti-slip rubber layer, and the support frame 42 is rotatably connected to the clamps via bearings. The rotation angle of the support frame 42 is controlled by a servo motor and is adjustable within the range of -45 degrees to 45 degrees.

[0072] In this way, the symmetrical clamps apply force evenly from both sides, ensuring the resin bucket 70 is subjected to balanced forces and avoiding displacement or deformation caused by clamping on one side. Furthermore, the anti-slip rubber layer increases friction through its surface texture, effectively preventing the resin bucket 70 from sliding. Simultaneously, the elasticity of the anti-slip rubber layer absorbs mechanical vibrations or impacts, preventing indentations on the resin bucket 70 during clamping. In addition, the support frame 42 is rotatably connected to the clamps via bearings. The bearings reduce frictional resistance, making the rotation of the support base 21 relative to the clamps smoother, suitable for scenarios where the resin bucket 70 needs to be tilted at multiple angles during filling.

[0073] Among them, the support bracket 42 is compatible with the resin tank 70, and the adjustment range of -45° to 45° covers most working scenarios. For example, the negative angle can help to completely discharge residual resin and avoid waste.

[0074] In some embodiments, the clamping mechanism 40 further includes a movable base plate 43, a robotic arm 44, and a positioning plate 45.

[0075] The bottom of the movable base plate 43 is provided with steering wheels. The movable base plate 43 is used to support the clamping assembly 41 and the robotic arm 44, so that the clamping mechanism 40 becomes a mobile infusion clamping mechanism 40, which can be transported by the steering wheels. The robotic arm 44 is mounted on the movable base plate 43 and is located on one side of the clamping assembly 41. The positioning plate 45 is mounted on the robotic arm 44. The positioning plate 45 is provided with a fixing member 451, which is used to fix the infusion pipeline 80 connected to the resin tank 70.

[0076] Of course, depending on actual needs, the above-mentioned fastener 451 can be a cable tie, which is used to fix the injection pipeline 80 to the positioning plate 45 to ensure the stability of the injection process.

[0077] In some embodiments, the clamping mechanism 40 further includes a weight sensor and a buzzer alarm.

[0078] A weight sensor is installed on the support frame 42 and is used to detect the weight of the resin bucket 70. A buzzer alarm is installed on the support frame 42 and is connected in communication with the weight sensor. The buzzer alarm is used to trigger a buzzer alarm when the weight of the resin bucket 70 is lower than a threshold.

[0079] In this way, the weight of the resin tank 70 is continuously monitored by a weight sensor. When the weight falls below a preset threshold (e.g., when the resin in the tank is about to run out), a buzzer alarm is immediately triggered. This design avoids interruptions in the filling process or imbalances in the ratio due to insufficient resin, ensuring that the mixing ratio of resin and hardener always meets the process requirements. In automated production lines, running out of resin tank 70 may cause the equipment to run idle or draw in air, leading to problems such as bubbles and uneven curing. Therefore, the timely response of the buzzer alarm can prevent such risks and reduce the defect rate.

[0080] In some embodiments, the stirring mechanism 20 includes a support base 21, a liftable stirring paddle 22, and a drive assembly 23.

[0081] The supporting base 21 includes a base body 211 and two clamping plates 212. The two clamping plates 212 are movably connected to the base body 211. The distance between the two clamping plates 212 is adapted to the diameter of the resin tank 70 to clamp the resin tank 70. The liftable stirring paddle 22 is used to stir the resin and curing agent in the resin tank 70. The drive assembly 23 is connected to the stirring paddle 22 and is used to drive the stirring paddle 22 to rotate.

[0082] In this embodiment, the stirring mechanism 20 adopts a high-speed stirrer and is equipped with a variable frequency motor, which can adjust the speed from 0 to 2000 rpm. At the same time, the stirring time countdown can be set to automatically stop. The rod of the stirring paddle 22 can be controlled to automatically rise or fall within 10 seconds. The blades of the stirring paddle 22 adopt a hollow design to prevent resin accumulation.

[0083] In some embodiments, the injection pipeline control mechanism 50 includes a control valve and a flow sensor. The control valve is installed at the outlet of the injection pipeline 80 connected to the resin tank 70, and the flow sensor is used to monitor the resin flow rate into the mold 90 in real time. The injection pipeline 80 is controlled by a two-position two-way solenoid valve, which controls the opening or closing of the injection pipeline according to the injection status to avoid resin waste and uneven injection.

[0084] A flow sensor monitors the resin flow rate in real time (with an accuracy of ±0.5% FS), and the data is fed back to the control system (such as a PLC) to dynamically adjust the opening of the control valve, achieving closed-loop control of the resin flow into mold 90. The control valve can quickly respond to changes in pipeline pressure, maintaining a constant flow output. In the production of PVC paste resin, this design reduces the flow deviation caused by pressure fluctuations from 15% in traditional designs to less than 5%. Simultaneously, the control valve can also instantly close (response time <0.1 seconds) when pouring is completed or mold 90 is switched, completely cutting off the resin flow.

[0085] In some embodiments, a pressure sensor is provided on the lid 32. The pressure sensor is used to detect the negative pressure state inside the barrel 31 and transmit the detection signal to the control unit (also known as the central control unit). The control unit controls the start and stop of the vacuum pump according to the detection signal.

[0086] The pressure sensor can detect changes in pressure inside the tank in real time (accuracy up to ±0.5% FS) and feed the data back to the control unit (such as a PLC). Once the pressure deviates from the set threshold (such as -0.08 MPa), the control unit immediately starts or stops the vacuum pump to ensure a stable negative pressure environment.

[0087] In addition, the barrel 31 is provided with an observation window, which is used to observe the degassing process inside the barrel 31.

[0088] In some embodiments, the inner side of the barrel lid 32 of the degassing mechanism 30 is provided with an annular sealing groove, and a silicone sealing ring is embedded in the groove; the suction port of the vacuum pump is connected to the vacuum interface at the top of the barrel lid 32 through a hose.

[0089] A vibrator is also installed at the bottom of the bucket lid 32, with an operating frequency of 40–60 Hz. The 40–60 Hz mechanical vibration generated by the vibrator (below the mid-to-high frequency range) creates micro-turbulence inside the resin, disrupts the surface tension of the bubbles, promotes the coalescence of small bubbles into larger bubbles, and accelerates their upward movement. For example, in epoxy resin degassing, this frequency vibration can increase the bubble rising speed by more than 50%.

[0090] It is important to emphasize that when the vibrator is linked with the vacuum pump, the vibration energy reduces the resin's viscous resistance, making it easier for bubbles to escape under negative pressure. Experiments show that the residual bubble amount is reduced by 70% compared to vacuum degassing alone, achieved by 40–60 Hz vibration combined with vacuum degassing (-0.08 MPa).

[0091] In some embodiments, the infusion device further includes a central control unit, which remotely controls the start-up and shutdown of the dispensing mechanism 10, the stirring mechanism 20, the defoaming mechanism 30, the infusion pipeline control mechanism 50, and the air extraction pipeline control mechanism 60 and adjusts their parameters via a communication module.

[0092] In summary, the working process of the injection device specifically includes: Before injection begins, the mixing mechanism 10 pours a fixed amount of resin and curing agent into the resin tank 70 according to the mixing instructions. Then, the resin tank 70 is transferred to the stirring mechanism 20, where the resin and curing agent in the resin tank 70 are stirred by the stirring mechanism 20, which has a pre-set stirring speed and stirring time. When the time is up, stirring stops. Then, the resin tank 70 is transferred to the degassing mechanism 30, where degassing is performed under vacuum. After the degassing is completed, the resin tank 70 is clamped by the clamping mechanism 40. Once everything is ready, the vacuum pipeline control mechanism 60 is opened to bring the negative pressure inside the mold 90 to below the specified value of -0.094MPa. Then, according to the resin flow pipeline layout of the mold 90, the injection pipeline control mechanism 50 is opened sequentially to allow the resin to be evenly introduced into the mold 90. After injection is completed, the injection pipeline control mechanism 50 is closed, and the composite material product in the mold cavity is left to cure naturally.

[0093] It should be noted that in this specification, relational terms such as first and second are used only to distinguish one entity from several other entities, and do not necessarily require or imply any such actual relationship or order between these entities.

The descriptions of the embodiments above are only for the purpose of helping to understand the solution and core ideas of this application. It should be noted that those skilled in the art can make several improvements and modifications to this application without departing from the principles of this application, and these improvements and modifications also fall within the protection scope of this application.
