Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of fuel tank manufacturing technology, and more specifically to novel molds for fuel tank blow molding and fuel tank manufacturing methods. Background Technology

[0002] like Figure 1 As shown, existing fuel tank blow molding dies typically employ a fixed blow needle chuck structure. Therefore, fuel tank production generally follows this process flow: mold opening—product removal—robot chuck installation—molding machine movement—pre-mold closing upon reaching the desired position—molding begins upon material placement—molding machine moves out while simultaneously blowing air for molding—molding completion and mold opening.

[0003] However, the inventors discovered that in this production process, mold opening typically takes 9 seconds, product removal takes 8 seconds, robot chuck installation takes 9 seconds, and the molding machine movement takes another 10 seconds. Because these processes need to be completed sequentially, the production time is long, impacting production efficiency.

[0004] Continuing, in the process of generating the oil tank using the novel mold disclosed herein, the following technical problem arises: how to determine whether the movable blow needle mechanism has moved into position. To address this technical problem, two methods are typically used. One method is to determine it based on the detection results of the positioning detection component; the other is to calculate it based on the movement of the driving component.

[0005] However, the aforementioned conventional solutions still have the following problems: In the first method, the position of the positioning and detection component is often fixed after installation. Therefore, it is impossible to fine-tune its position according to actual conditions. Furthermore, this method lacks monitoring of the drive components, making it impossible to detect drive component malfunctions in a timely manner, thus affecting production efficiency. The second method calculates and determines the movement position of the blow-off mechanism solely based on the movement of the drive components. Over time, the drive components may experience wear, malfunctions, etc., resulting in a deviation between the calculated and actual movement positions. Moreover, this deviation may vary. This affects the accuracy of positioning in the production of new molds.

[0006] The information disclosed in this background section is only intended to enhance the understanding of the background of the present disclosure concept, and therefore may contain information that does not constitute prior art known to those skilled in the art. Summary of the Invention

[0010] In some embodiments, the second end of the support frame is provided with two parallel sliding grooves; the sliding platform consists of multiple parallel inclined plates, each inclined plate having pulleys installed on both sides of its lower end, and a snap-fit ​​device provided between two adjacent inclined plates to restrict the sliding of the inclined plates along the sliding groove, wherein the two ends of the inclined plates are parallel to the extending direction of the sliding groove.

[0011] In some embodiments, a first moving component is mounted on a sliding platform and includes a first driving component and a moving component. The first driving component is connected to the moving component, and the lower end of the moving component is fixed to the sliding platform.

[0012] In some embodiments, the moving component includes a plurality of parallel slide rails, a plurality of sliders that move along the slide rails, and a locking member. The lower end of the slide rail is fixed to the sliding platform. One end of the locking member is fixedly connected to the slider, and the other end is locked and fixed to the blow needle assembly. The first driving component is a cylinder. One end of the cylinder is fixed to the sliding platform, and the driving rod at the other end of the cylinder is connected to the blow needle assembly.

[0013] In some embodiments, the blow needle assembly includes a cylindrical platform and a blow needle component. The cylindrical platform has a through hole at its axial center, and the blow needle component passes through the through hole through the cylindrical platform. The outer surface of the cylindrical platform is engaged and fixed with a clamping component, and a chuck is mounted on the end face of the cylindrical platform facing the first mold assembly. The chuck has a clearance hole at the position corresponding to the blow needle component.

[0014] In some embodiments, the novel mold further includes a second mold assembly, the lower end of which is formed with a second groove adapted to the shape of the second outer surface of the oil tank, wherein the second outer surface and the first outer surface are opposite sides and constitute the outer surface of the oil tank; the lower end of the second mold assembly and the upper end of the first mold assembly are respectively provided with mutually cooperating mold closing fixing members, wherein, in the mold closing state of the novel mold, the lower end of the second mold assembly contacts the upper end of the first mold assembly and is fixed by the mold closing fixing members.

[0015] Secondly, some embodiments of this disclosure provide a method for producing a fuel tank, employing a novel mold for blow molding of a fuel tank as described in any implementation of the first aspect above, comprising: in response to determining that the fuel tank blow molding is complete, controlling a first moving component in a movable blow-pin mechanism to move, so that the blow-pin assembly moves away from a first mold assembly; in response to determining that the first moving component has moved into place, controlling a second moving component in the movable blow-pin mechanism to move, so that the blow-pin assembly moves away from a support frame; in response to determining that the second moving component has moved to the outside of the novel mold, controlling a robot arm to mount a chuck onto the blow-pin assembly; in response to Upon confirming that the chuck installation is complete, the second moving component and the first moving component are sequentially controlled to move so that the blow needle component passes through the blow needle hole on the first mold component and into the first groove.

Specifically, after the fuel tank blow molding is completed, before or during mold opening, the movable blow needle mechanism can move away from the first mold assembly (i.e., towards the rear of the mold) under the action of the first moving component, thereby avoiding structural interference. Then, under the action of the second moving component, it can continue to move away from the support frame (i.e., towards the outside of the mold), thus reaching the outside of the mold. In this way, the chuck can be installed on the outside of the mold. Compared with the fixed blow needle structure, the novel mold of this disclosure reduces the problem of chuck pre-embedded installation occupying cycle time, thereby shortening the production time of a single fuel tank and improving overall production efficiency.

[0029] This disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Figure 2 This diagram illustrates the structural schematic of some embodiments of the novel mold for blow molding of fuel tanks disclosed herein. The novel mold may include a support frame 1, a first mold assembly 2, and a movable blow-needle mechanism 3. Here, the support frame 1 can constitute the main structure of the novel mold for fixing and supporting other components on the mold. A first groove 21 may be formed at the upper end of the first mold assembly 2. The first groove 21 is adapted to the shape of the first side outer surface of the fuel tank. A blow-needle hole is also provided within the first groove 21. The lower end of the first mold assembly 2 can be fixed to the first end of the support frame 1. The upper and lower ends are typically opposite ends. The lower end is typically the end facing or close to the ground when using the mold.

[0031] Here, the blow-off mechanism in the novel mold of this application adopts a non-fixed, movable blow-off mechanism. For example... Figure 2As shown, the movable blow needle mechanism 3 in this application may include a blow needle assembly 31, a first moving assembly 32, and a second moving assembly 33. The blow needle assembly 31 can be mounted on the upper end of the first moving assembly 32 and can pass through the aforementioned blow needle hole into the first groove 21. Additionally, a chuck 4 can be mounted on the end face (i.e., the upper end) of the blow needle assembly 31 facing the first mold assembly 2. The first moving assembly 32 can be fixedly connected to the second moving assembly 33 and can reciprocate in directions approaching and away from the first mold assembly 2. The second moving assembly 33 can be movably connected to the second end of the support frame 1 and can reciprocate in directions approaching and away from the support frame 1. It should be noted that the movement direction of the first moving assembly 32 is perpendicular to the movement direction of the second moving assembly 33.

[0032] As described above, some embodiments of the novel mold for blow molding of fuel tanks disclosed herein can achieve simultaneous installation of the chuck and other production processes by replacing the existing fixed blow needle structure with a movable blow needle mechanism. Specifically, after the fuel tank blow molding is completed, before or during mold opening, the movable blow needle mechanism can move away from the first mold assembly (i.e., towards the rear of the mold) under the action of the first moving component, thereby avoiding structural interference. Then, under the action of the second moving component, it can continue to move away from the support frame (i.e., towards the outside of the mold), thus moving to the outside of the mold. In this way, the chuck can be installed on the outside of the mold. Furthermore, before the mold is pre-closed, the chuck can be pre-embedded and installed inside the fuel tank by moving and resetting the movable blow needle mechanism. Compared with the fixed blow needle structure, the novel mold of this disclosure can reduce the cycle time occupied by the pre-embedded installation of the chuck, thereby shortening the production time of a single fuel tank and improving overall production efficiency.

[0033] It is understandable that the structures of the first moving component 32 and the second moving component 33 described above can be configured according to actual needs, as long as they can achieve unidirectional movement functionality. For example, as shown... Figure 2 As shown, the second moving component 33 may include a second driving component (not shown) and a sliding platform 331. Here, the second driving component is connected to the sliding platform 331, and the sliding platform 331 is slidably connected to the second end of the support frame 1. A first sliding component may be provided at the lower end of the sliding platform 331, while a second sliding component adapted to the first sliding component may be provided at the upper end of the second end of the support frame 1 facing the sliding platform 331. The second driving component may employ a cylinder, hydraulic cylinder, stepper motor, ball screw, or similar structure. The sliding method and structure of the first and second sliding components are not limited. For example, the first sliding component may be a pulley, slider, etc., and the second sliding component may be a corresponding groove, rail, etc.

[0034] In some embodiments, the sliding platform 331 can be a single flat plate structure. For example... Figure 3A As shown, the sliding platform 331 can also consist of multiple parallel inclined plates. Each inclined plate can have pulleys mounted on both sides of its lower end. In this case, the second end of the support frame 1 can be provided with two parallel sliding grooves. The pulleys on both sides of the inclined plate can respectively engage with the two sliding grooves. Additionally, a locking element can be provided between adjacent inclined plates. For example, one inclined plate may have a locking groove in the middle, and another inclined plate may have a protruding locking block at the corresponding position. The shapes of the locking groove and the locking block can be set according to actual needs. Through the engagement of the locking element, the inclined plates can be restricted to sliding only along the sliding groove, thereby preventing movement in directions other than the sliding direction. It is understood that, in order to minimize the size of the sliding platform and reduce structural interference, the two ends of each inclined plate can be parallel to the extension direction of the sliding groove.

[0035] Furthermore, the first moving component 32 can be mounted on the sliding platform 331. Here, as... Figure 2 As shown, the first moving component 32 may include a first driving component 321 and a moving component 322. The first driving component 321 is connected to the moving component 322, and the lower end of the moving component 322 is fixed to the sliding platform 331. The structure of the first driving component and the moving component is not limited here.

[0036] As an example, such as Figure 2 As shown, the moving component 322 may include multiple parallel slide rails A, multiple sliders B that move along the slide rails, and a locking member C. The lower end of the slide rail A is fixed to the sliding platform 331. One end of the locking member C can be fixedly connected to the slider B, and the other end of the locking member C can be locked and fixed to the blow needle assembly 31. The locking member C secures the blow needle assembly 31 to the first moving component 32. Furthermore, the first moving component 32 secures the blow needle assembly 31 to the second moving component 33. Here, the first driving component 321 can be a cylinder. One end of the cylinder (i.e., the fixed end) can be fixed to the sliding platform 331, while the driving rod at the other end of the cylinder can be connected to the blow needle assembly 31. Thus, under the driving action of the cylinder driving rod, the blow needle assembly 31 can move up and down along the slide rail A (i.e., move closer to or away from the first mold assembly). Additionally, from... Figure 2 As can be seen, multiple slide rails A can be installed on different inclined plates according to position requirements.

[0037] Alternatively, the slide rail A and slider B can be replaced with multiple parallel telescopic rods. The lower end of the telescopic rod can be fixed to the sliding platform, and the upper end can be fixed to a clamp. In this way, under the driving action of the cylinder and the limiting action of the telescopic rod, the up and down movement of the blow needle assembly can also be achieved.

[0038] In some embodiments, the blow needle assembly 31 may include a cylindrical platform 311 and a blow needle component 312. The cylindrical platform 311 may have a through hole at its axial center, through which the blow needle component 312 can pass. The outer surface of the cylindrical platform 311 is engaged and fixed with a retainer C. Here, the cylindrical platform 311 and the retainer C may employ a transition fit. A chuck may be mounted on the end face of the cylindrical platform 311 facing the first mold assembly. In this case, the chuck may have a clearance hole at the position corresponding to the blow needle component 312.

[0039] It should be noted that, Figure 3A The W1 position shown indicates the location of the movable blow needle mechanism during production. Figure 3B The structure shown. Figure 3A The position W2 shown indicates the position of the movable blow needle mechanism during movement. Figure 3A The W3 position shown indicates the location where the movable blow needle mechanism is moved to the outside of the mold, i.e., the position when the chuck is installed.

[0040] In some embodiments, the novel mold disclosed herein may further include a second mold assembly (not shown in the figures). The lower end of the second mold assembly may also have a second groove adapted to the shape of the second outer surface of the fuel tank. The second outer surface and the first outer surface are opposite sides and constitute the overall outer surface of the fuel tank. That is, a complete outer surface structure of the fuel tank is formed on the first mold assembly and the second mold assembly. Furthermore, the lower end of the second mold assembly and the upper end of the first mold assembly are respectively provided with mutually cooperating mold-closing fixing members. The structure of the mold-closing fixing members is not limited. In the mold-closing state of the novel mold, the lower end of the second mold assembly can contact the upper end of the first mold assembly, and the two are fixed together by the mold-closing fixing members.

[0041] Embodiments of this disclosure also provide a method for manufacturing fuel tanks. This method can employ the novel mold for blow molding of fuel tanks described in any of the above embodiments. See the detailed process below. Figure 4 This may include the following steps:

[0042] In response to determining that the oil tank blow molding is complete, the first moving component in the movable blow needle mechanism is controlled to move so that the blow needle assembly moves away from the first mold assembly;

[0043] In response to determining that the first moving component has moved into place, the second moving component in the movable needle mechanism is controlled to move so that the needle assembly moves away from the support frame.

[0044] In response to determining that the second moving component has moved to the outside of the new mold, the control robot arm is used to install a chuck onto the blow needle assembly;

[0045] In response to the confirmation that the chuck installation is complete, the second moving component and the first moving component are controlled to move sequentially, so that the blow needle assembly passes through the blow needle hole on the first mold assembly and enters the first groove.

[0046] During the movement of the movable blow needle mechanism, the second mold assembly is controlled to move away from the first mold assembly in order to complete the mold opening of the new mold;

[0047] In response to the confirmation that the mold opening is complete, the robot arm is controlled to remove the oil tank product from the new mold, and the second mold assembly is controlled to move towards the first mold assembly to complete the mold closing of the new mold;

[0048] In response to the confirmation that the mold closing is complete, the blow needle assembly is controlled to blow air into the first and second grooves to complete the blow molding of the oil tank.

[0049] Understandably, because the blow-off needle structure in existing molds is fixed, when installing the chuck, the mold must be opened first, the box removed, and then the robot arm enters the mold to install it. However, with the novel mold and fuel tank production method of this application, because a movable blow-off needle mechanism is used, this mechanism can slide backward before the mold opens. After sliding backward to its final position, the blow-off needle mechanism can slide outward from the mold. After sliding outward to its final position, the robot arm can directly install the chuck. Thus, the robot arm can install the chuck while the box is being removed. In other words, using the new mold disclosed herein, the chuck can be installed simultaneously with mold opening, product removal, and the movement of the molding machine. This reduces waiting time during production and improves fuel tank production efficiency.

[0050] In some embodiments, considering the problems with conventional solutions, the second technical problem mentioned above—how to determine whether the movable blow needle mechanism has moved into place—is addressed. With the rapid development of artificial intelligence (AI) technology, various AI applications have already emerged around us, such as autonomous driving, facial recognition, intelligent robots, machine translation, and self-service machines. The goal of AI is to enable machines to think and make decisions like humans. For machines to think, they must first learn, summarize patterns from experience, and thus possess certain decision-making and discernment abilities. This is the core of AI—machine learning. Therefore, combining the powerful learning and predictive capabilities of machine learning models, the following solution can be adopted.

[0051] A positioning detection component can be installed at either end of the second end of the support frame to detect the actual movement position of the second moving component in the direction of approaching and moving away from the support frame. This positioning detection component can typically be a non-contact distance sensor. For example, a signal transmitter and a signal receiver can be installed on the support frame, and a reflector can be installed at a corresponding position on the side of the sliding platform in the second moving component. Alternatively, a signal transmitter and a signal receiver can be installed on the sides of the support frame and the sliding platform, respectively. Furthermore, an image acquisition component can be installed at the upper end of the first moving component (such as a card) to acquire images of the blowhole on the first mold assembly directly above it.

[0052] In some embodiments, during the movement of the movable blow-off needle mechanism, especially during its movement into the new mold after the chuck is installed, the oil tank production method of this disclosure can collect motion data of the first and second driving components. The motion data, detection data from the positioning detection component, and image data acquired by the image acquisition component can be sent to a communication-connected artificial intelligence chip. The artificial intelligence chip can analyze and determine the fine-tuning movement of the second moving component. Simultaneously, the movement of the second driving component can be monitored.

[0053] Here, the AI ​​chip first determines the movement error of the second moving component based on the motion data of the second driving component (i.e., the rated movement distance) and the detection data of the positioning detection component (i.e., the actual movement distance). If the movement error is less than the error threshold, the distance difference between the blow needle component and the blow needle hole in the movement direction of the second moving component can be further determined based on the image data acquired by the image acquisition component. This distance difference allows for fine-tuning of the second driving component's movement. The detection data from the positioning detection component is then used to determine whether the fine-tuning has reached the correct position. After confirming that the second moving component has reached the correct position, the first moving component can be controlled to begin moving. This ensures the accuracy of the second moving component's movement and guarantees accurate docking of the subsequent blow needle component and blow needle hole. Furthermore, it enables fine-tuning of the position, reducing or avoiding the impact of production errors, equipment errors, and other factors.

[0054] It should be noted that using models to solve problems encountered in production and daily life is becoming increasingly common, such as time series models. Time series models are mathematical models typically established based on time series data obtained from system observations, through curve fitting and parameter estimation. They generally employ curve fitting and parameter estimation methods (such as nonlinear least squares). Time series models have been widely used in areas such as national economic macroeconomic control, regional comprehensive development planning, enterprise operation and production management, market potential forecasting, and weather forecasting.

[0055] In production and scientific research, the observation and measurement of one or a group of variables, arranged chronologically at a series of moments, and used to explain the variables and their relationships, result in a discrete set of numbers, commonly known as a time series. This time-meaning sequence is also called dynamic data. Such dynamic data is common in natural, economic, and social fields. Motion errors in drive components due to wear and tear also fall under the category of time series. Therefore, time series models can be used to monitor drive components.

[0056] Here, artificial intelligence chips are often referred to as AI accelerators or computing cards, which are modules specifically designed to handle the massive computational tasks in artificial intelligence applications. These chips typically house machine learning models. The AI ​​chip can also use motion data from the second driving component and detection data from the positioning and detection component as training samples to train the machine learning model, thereby predicting the motion error of the second driving component and enabling monitoring of the driving component. Specifically, the motion data sequence and detection data sequence before time t can be used as input to predict the motion error at time t. The actual motion error values ​​of the motion data and detection data at time t can be used as sample labels. The model parameters of the machine learning model can then be adjusted based on the loss function value between the sample labels and the predicted motion error. After this training, the machine learning model can be used to predict the motion error of the driving component. When the predicted motion error exceeds an error threshold, an alarm can be issued, allowing for early maintenance of the driving component, reducing production defects, and minimizing the impact on production. The machine learning models used here can be time series models, such as ARMA (autoregressive moving average) models and LSTM (Long Short-Term Memory) models.

[0057] In some embodiments, the AI ​​chip can communicate with other electronic devices via a bus such as PCIe to receive or send information. PCIe (Peripheral Component Interconnect Express) is typically a high-speed serial computer expansion bus standard. The AI ​​chip can use received training and / or test data to train and / or test machine learning models stored on it. Additionally, the AI ​​chip can analyze and predict relevant data, such as motion errors of driving components, based on the trained model.

[0058] Here, the artificial intelligence chip may include a storage component, at least one general-purpose execution component, and at least one special-purpose execution component. The storage component may be a circuit or device capable of performing information storage functions. Examples include Static Random-Access Memory (SRAM), Random Access Memory (RAM), memory modules, Secure Digital Memory Cards (SD cards), or Flash Memory Cards (TF cards, also known as microSD cards). The storage component may store one or more programs.

[0059] In some embodiments, a general-purpose execution unit can be used to receive data and send data to corresponding dedicated execution units. For example, the general-purpose execution unit may include a programmable general-purpose computing graphics processor, such as an ARM (Advanced RISC Machine or Acorn RISC Machine) core, a 51 core, etc. The dedicated execution unit can be used to receive and process the data sent by the general-purpose execution unit. For example, the dedicated execution unit may include an execution unit dedicated to position fine-tuning computation tasks, such as an image recognition analysis processor and a position computation processor. As another example, the dedicated execution unit may also include an execution unit dedicated to processing computationally intensive computational tasks in machine learning models, such as an activation data processor, a pooling data processor, a general-purpose data processor, a parameter tuning processor, etc. The activation data processor can be used for data processing in the model activation function layer. The pooling data processor is used for data processing in the model pooling layer. The general-purpose data processor is used for data processing in the model normalization layer. The parameter tuning processor can be used for backpropagation computation and model parameter adjustment.

[0060] Similarly, a positioning detection component can also be provided on the first moving component. For example, detection sensors, such as patch pressure sensors or photosensitive sensors, can be set around the surface of the cylindrical platform. When the detection signal of the sensor changes, it indicates that the blow needle assembly has passed through the blow needle hole into the first groove. This ensures the accuracy of the movement of the first moving component and also enables monitoring of the first driving component.

[0061] The following is for reference. Figure 5 It shows a schematic diagram of the structure of an electronic device 500 suitable for implementing some embodiments of the present disclosure. Figure 5 The electronic device shown is merely an example and should not be construed as limiting the functionality and scope of the embodiments of this disclosure.

[0062] like Figure 5As shown, the electronic device 500 may include a processing unit 501 (e.g., a central processing unit, a graphics processor, etc.), which can perform various appropriate actions and processes according to a program stored in a read-only memory (ROM) 502 or a program loaded from a storage device 508 into a random access memory (RAM) 503. The RAM 503 also stores various programs and data required for the operation of the electronic device 500. The processing unit 501, ROM 502, and RAM 503 are interconnected via a bus 504. An input / output (I / O) interface 505 is also connected to the bus 504.

[0063] Typically, the following devices can be connected to I / O interface 505: input devices 506 including, for example, touchscreens, touchpads, keyboards, mice, cameras, microphones, accelerometers, gyroscopes, etc.; output devices 507 including, for example, speakers, vibrators, etc.; storage devices 508 including, for example, disks, hard disks, etc.; and communication devices 509. Communication device 509 allows electronic device 500 to communicate wirelessly or wiredly with other devices to exchange data. Although Figure 5 An electronic device 500 with various devices is shown; however, it should be understood that it is not required to implement or possess all of the devices shown.
