Description

Technical Field

[0001] Embodiments of the present disclosure relate to the technical field of fuel tank manufacturing, and in particular to an improved built-in component fixture. Background Art

[0002] like Figure 1A and 1B The existing built-in component fixture shown, when using a robot arm to manipulate the mounting plate to install the built-in component, will install a molten component one on the built-in component, and also install a molten component two at the corresponding position inside the oil tank. In this way, the robot arm can be used to manipulate the mounting plate to align the molten component one and the molten component two. After that, the molten component heating mechanism can be used to heat the surface of the molten component one and the surface of the molten component two to make them molten. Next, the robot arm manipulates the mounting plate to make the surfaces of the molten component one and the molten component two butt and fuse. After the built-in component is fixed to the oil tank, the mounting plate can be operated by the robot arm again to leave for the next installation of the built-in component.

[0003] However, in the actual production process, the inventors found that since multiple built-in parts holding mechanisms are fixed on the mounting plate, and the built-in parts clamping mechanisms are generally installed on the mounting plate through the base plate 1. The base plate 1 and the mounting plate are often fixed. Therefore, in the process of using the built-in parts fixture to fix multiple built-in parts to the fuel tank at the same time, the mounting plate will drive each built-in part (molten part 1) to move the same distance to the molten part 2. However, in the process of producing fuel tanks, there may be slight differences in the wall thickness of each fuel tank. This will also result in a certain difference in the height or thickness at the same position where the molten part 2 is installed inside each fuel tank. Therefore, when the molten part 1 and the molten part 2 are docked and fused, due to the above-mentioned size differences, some may not be fully in contact, and some may have excessive extrusion pressure. This will also result in defective products due to poor fixation of the built-in parts.

[0004] Next, in the actual production process using the improved built-in fixture disclosed in the present invention, the following technical problems further exist:

[0005] The parameter adjustment of the driving component is usually determined based on the installation results of the last built-in component. This can only reduce the number of defective products produced later. However, defective products produced in the last installation are usually unavoidable. In addition, the thickness of each oil tank at the location where the built-in component is installed is different, which makes the parameter adjustment of the driving component have a certain error.

[0006] The above information disclosed in this Background section is only for enhancement of understanding of the background of the present disclosure concept and therefore it may contain information that does not form the prior art that is already known in this country to a person of ordinary skill in the art.

[0009] In some embodiments, the proportional control valve is an electric proportional valve, the actuator is a cylinder, the electric proportional valve is connected to the cylinder through a gas pipeline, and the piston rod of the cylinder is fixed to a base plate.

[0010] In some embodiments, the built-in component fixture further includes a detection component 1, which is disposed on the end surface of the clamping component facing the molten component 2.

After the two clamping hands move, they clamp or unclamp the internal component.

[0012] In some embodiments, the detection component 1 is a patch pressure sensor, which is distributed and applied to the end surface of the clamping portion facing the molten component 2, and is used to detect the docking pressure between the molten component 1 and the molten component 2 during the docking and fusion process.

[0013] In some embodiments, the clamping portion is provided with at least two grooves on the end surface facing the second molten member, and the first molten member is provided with through holes at positions corresponding to the grooves; the detection member 1 is a distance measuring sensor, which is respectively arranged in the grooves, and is used to detect the distance between the detection member 1 and the surface of the second molten member before the heating mechanism of the molten member is heated.

In addition, the height or thickness difference at the same position where the molten component 2 is installed inside different oil tanks can be eliminated. In this way, the number of defective products produced can be reduced, which helps to improve the yield rate of the overall oil tank production and reduce the waste of raw materials.

[0027] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0028] Figure 2The following is a partial structural schematic diagram of some embodiments of the improved built-in component fixture disclosed in the present invention. Figure 1A and Figure 1B In the embodiment of the present disclosure, the improved built-in component fixture may include a mechanical arm 1, a mounting plate 2, a built-in component clamping mechanism 3 and a molten component heating mechanism 6. Figure 1A and Figure 1B As can be seen in the figure, the mounting plate 2 can be connected to the robot arm 1. Here, the mounting plate 2 can constitute the mounting body of the built-in component fixture. A plurality of built-in component clamping mechanisms 3 are mounted on the mounting plate 2.

[0029] Specifically, each built-in component clamping mechanism 3 may include a driving component 300, a bottom plate 301 and a clamping component. Figure 2 As shown, the driving component 300 is mounted on the first end surface of the mounting plate 2. One end of the bottom plate 1 301 is fixed to the moving rod of the driving component 300. The clamping component is mounted on the other end of the bottom plate 1 301 for clamping the built-in component 4. Here, the moving rod moves in a direction perpendicular to the first end surface of the mounting plate 2. The first end surface is usually the end surface of the mounting plate 2 facing the inner wall of the oil tank.

[0030] Further, the melting piece 1 5 can be arranged on the built-in part 4. At the same time, a melting piece 2 (not shown in the figure) can be correspondingly arranged on the inner wall of the oil tank. The melting piece heating mechanism 6 is also installed on the first end face of the mounting plate 2. The melting piece heating mechanism 6 here is used to heat the surface of the melting piece 1 and the surface of the melting piece 2 at the same time. It can be understood that by moving the moving rod in the driving component 300, a slight adjustment of the distance between the melting piece 1 5 and the melting piece 2 can be achieved.

[0031] In the disclosed embodiment, in order to install the built-in component 4 inside the oil tank, a molten component 1 5 can be installed on the built-in component 4, and a molten component 2 can also be installed at a corresponding position inside the oil tank. During the installation process, the mounting plate 2 can first be manipulated by the robot arm 1 to align the molten component 1 5 with the molten component 2. Then, the surfaces of the molten component 1 5 and the molten component 2 are heated by the molten component heating mechanism 6 to make them molten. After that, the mounting plate 2 can be manipulated by the robot arm 1 again to make the molten component 1 5 and the molten component 2 meet to achieve docking and fusion of the surfaces of the two.

[0032] If after the installation of the built-in parts of the previous oil tank is completed, there are one or some built-in parts that are not fixed properly, such as the deviation in the thickness of the oil tank described in the background technology section, resulting in the failure of molten piece 1 and molten piece 2 to be completely docked and bonded. Then, before installing the built-in parts in the next oil tank, the parameters of the driving components in the corresponding built-in component clamping mechanism can be adjusted first. Thus, when the built-in parts are installed next time, the molten piece 1 on it is closer to the corresponding molten piece 2. This can reduce or avoid the above-mentioned problem of incomplete docking and bonding. In other words, during the docking and fusion process between the surface of molten piece 1 and the surface of molten piece 2, the docking pressure between molten piece 1 and molten piece 2 on each built-in component clamping mechanism can be controlled separately by the driving component. This can eliminate the influence of the height or thickness difference at the same position where molten piece 2 is installed inside different oil tanks. Thereby, the number of defective products produced can be reduced, which helps to improve the yield rate of the overall oil tank production and reduce the waste of raw materials.

[0033] The specific workflow is to place the built-in component 4 on the built-in component clamping mechanism 3 in advance so that it remains stable on the mounting plate 2. After the mold separates the fuel tank blank, the robot arm 1 can drive the mounting plate 2 to move between the two halves of the blank according to the specified path, so that the built-in component 4 corresponds to the predetermined installation position, that is, the molten component 1 5 corresponds to the molten component 2. Then the robot arm 1 continues to drive the mounting plate 2 to move, so that the molten component 1 5 gradually approaches the molten component 2. When the two are at a certain distance, the molten component heating mechanism 6 is started to heat the two opposite surfaces of the molten component 1 5 and the molten component 2. When the two surfaces are heated to a molten state, the molten component heating mechanism 6 cancels the heating. The robot arm 1 drives the mounting plate 2 to move again, so that the two surfaces of the molten component 1 5 and the molten component 2 fit together. And each driving component 300 can control the docking pressure between the two according to the set parameters. After the docking fusion is completed, the built-in component clamping mechanism 3 releases the built-in component 4, and the robot arm 1 drives the mounting plate 2 to reset, completing the installation of the built-in component 4.

[0034] It should be noted that the driving component 300 of the present disclosure can be set according to actual needs, and can be moved in a direction perpendicular to the first end surface of the mounting plate. In addition, in order to achieve precise control, the driving component 300 here may include a proportional control valve (not shown in the figure) and an actuator. Among them, the proportional control valve can also be installed on the mounting plate 2, which is connected to the actuator through a pipeline. And the moving rod on the actuator is fixed to the bottom plate 1 301.

[0035] As an example, the actuator may be a hydraulic cylinder, and the proportional control valve may be an electro-hydraulic proportional valve. For another example, in order to simplify the structure and reduce the cost, the actuator may be a gas cylinder, and the proportional control valve may be an electric proportional valve. In this case, the electric proportional valve is connected to the gas cylinder through a gas pipeline, and the piston rod of the gas cylinder is fixed to the bottom plate 301. It is understandable that, if Figure 3A As shown, the installation method of each actuator can be determined according to the actual installation position of the corresponding built-in component. For example, it can be directly fixed on the mounting plate 2, or the actuator can be fixed to the mounting plate 2 by a fixing member to increase the extension length of the clamping component to meet the use requirements.

[0036] It is understandable that the above parameter adjustment of the driving component 300 is usually determined based on the installation result of the last built-in component. This can only reduce the number of defective products produced later. However, defective products produced in the last installation are usually unavoidable. In addition, the thickness of each oil tank at the location where the built-in component is installed has certain differences, which makes the parameter adjustment of the driving component have certain errors.

[0037] Therefore, in order to solve this problem, in some embodiments, the built-in component fixture may further include a detection component 8. The detection component 8 may be arranged on the end face of the clamping component facing the molten component 2. And the detection component 8 may be electrically connected to the driving component 300. In this way, according to the detection result of the detection component 8, the setting parameters of the driving component 300 may be dynamically adjusted. In other words, by setting the detection component 8, the current installation process may be detected, so that the setting parameters of the driving component 300 may be adjusted in real time to adjust the installation pressure of the current built-in component. That is, the detection data of the built-in component during the current installation process is used to adjust the setting parameters of the driving component during the current installation process. This is conducive to ensuring the accuracy of parameter adjustment, and can further reduce the number of defective products, especially reduce the probability of defective products produced by the current installation. It can be understood that the detection method and installation position of the detection component 8 can also be set according to actual needs.

[0038] In some embodiments, the clamping component may include a limiter 302 and two grippers 304. Here, the limiter 302 may be arranged on the bottom plate 301, and the limiter 302 has a clamping portion 303. The built-in component 4 may be arranged on the clamping portion 303. For example, the built-in component 4 may be sleeved on the clamping portion 303 of the limiter 302, and the groove corresponding to the clamping portion 303 on the built-in component 4 may adopt an overfitting or interference fit with the clamping portion 303. In addition, the two grippers 304 may be movably arranged on the bottom plate 301. The two grippers 304 move toward each other, and the moving direction of the grippers 304 is perpendicular to the moving direction of the moving rod of the driving component 300. Here, the two grippers 304 may clamp or cancel the clamping of the built-in component 4 after moving. For example, the gripper 304 may be a two-jaw power chuck, and its moving direction is parallel to the first end face of the mounting plate 2. The gripper 304 is used to clamp the side of the built-in component 4 to keep it stable. Here, the built-in component 4 may be fastened to the clamping portion 303 first, and then the clamping hands 304 clamp the two sides of the built-in component 4 .

[0039] In some application scenarios, such as Figure 3AAs shown, the clamping portion 303 may be provided with at least two grooves C on the end surface facing the molten part 2. The molten part 1 is formed with a through hole at the position corresponding to the groove C. Here, the detection part 1 8 may be a distance sensor, which is respectively arranged in the groove C. Among them, the distance sensor may be a laser sensor. In order to avoid affecting the docking fusion, the laser emitting end and the receiving end may be simultaneously arranged on the clamping part. In this way, before the molten part heating mechanism is heated, the distance sensor can detect the distance between the surface of the molten part 2. If the measured distance is greater than the distance detected last time, or the set standard distance value, the driving component 300 can further drive the molten part 1 to move in the direction close to the molten part 2, thereby increasing the docking pressure between the two.

[0040] It is understandable that, since the molten part 1 and the molten part 2 are butt joints, multiple (at least two) detection parts 1 8 can be provided on the clamping part 303, which can help improve the accuracy of the detection result. At this time, the average value or minimum value of the multiple detection results can be used as the final detection result to adjust the setting parameters of the driving component.

[0041] It should be noted that the above-mentioned distance measuring sensors usually adopt non-contact detection, and can often only perform point measurement, and the measurement data is limited and less. This will affect the accuracy of the detection results of the distance measuring sensor, thereby affecting the accuracy of the adjustment of the drive component parameters, and further affecting the yield rate of the built-in component installation. In addition, if a laser sensor is used, corresponding safety protection measures need to be set. This not only requires major changes to the original production structure, but also increases the cost of improvement.

[0042] To solve this problem, optionally, Figure 3B As shown, the detection component 1 8 can be a patch pressure sensor, which can be distributed and applied to the end surface of the clamping part 303 facing the molten component 2. In this way, during the docking and fusion process of the molten component 1 and the molten component 2, the patch pressure sensor can detect the docking pressure between the two. If the detected docking pressure value is less than the docking pressure value detected last time, or the set standard pressure value, the driving component 300 can further drive the molten component 1 to move in the direction close to the molten component 2, thereby increasing the docking pressure between the two.

[0043] Here, if Figure 3B As shown, the patch pressure sensor can be attached to the entire end face of the card part. In this way, during the docking and fusion process, the docking pressure of the entire docking surface can be detected, thereby improving the accuracy of the detection results. Adjusting the drive component according to the accurate detection results is conducive to ensuring that the surfaces of molten part 1 and molten part 2 are in full contact, thereby improving the yield rate of built-in component installation. In addition, this detection method does not require major changes to the original structure, nor does it require the setting of corresponding safety protection measures.

[0044] Furthermore, in order to improve the reliability of the installation and fixation of the built-in components, the built-in component fixture disclosed in the present invention may also include a welding manipulator for welding the outer ring at the connection between the molten component 1 5 and the molten component 2. Here, the front end of the welding manipulator may include a C-shaped upper half and a C-shaped lower half. The upper half and the lower half are hinged on the outside of the adjacent end. And the other end of the upper half and the lower half can make an up and down opening and closing movement around the hinge axis. Among them, after the upper half and the lower half are combined, they can be adapted to the outer ring at the connection between the molten component 1 5 and the molten component 2.

[0045] In some embodiments, the inner side of the upper half and the lower half is provided with a groove along the extension direction thereof, and a plurality of heating pins are provided at the bottom end of the groove. A heating element is provided inside the top of the heating pin. It is understandable that the arrangement and layout of the heating pins are not limited, such as an array. In addition, a bottom plate penetrating the heating pins is provided in the groove, and guide rails are provided on both sides of the non-extension direction of the groove. In this way, under the action of the guide rails, the bottom plate can move up and down in the depth direction of the groove. At the same time, a driving rod connected to the bottom plate is provided on the outer side of the upper half and the lower half. Pressing the driving rod can move the bottom plate toward the top of the groove.

[0046] Furthermore, a welding rod may be placed inside the groove. A through hole is formed in the welding rod at a position corresponding to the heating ejector pin. The heating ejector pin may be embedded in the welding rod through the through holes. When the welding rod is placed in the groove, the top of the welding rod, the groove and the heating ejector pin may be flush. The top here is usually the end face away from the bottom end of the groove.

[0047] The specific welding process is: when the surfaces of molten piece one and molten piece two are butt-fused, the welding manipulator can move here and control the upper and lower parts to open so that the butt-fusion point is located between the upper and lower parts of the welding manipulator. After that, the upper and lower parts can be controlled to merge to wrap the butt-fusion point. Then the heating ejector pin can be started for heating so that the welding strip wraps around molten piece one and molten piece two at the butt-fusion point and fuses with them, thereby realizing the welding of the outer circle of the fusion point. After the welding is completed, the welding manipulator can press the drive rod to separate the welding strip from the heating ejector pin through the bottom plate and push it out of the groove. And the welding manipulator can control the upper and lower parts to open, thereby completing this welding. Before the next welding, the welding strip can be placed in the groove. And during the placement process, the welding strip can push the bottom plate to the bottom end of the groove again, so that the drive rod connected to it extends to the outside of the upper half (and the lower half).

[0048] It is understandable that in the existing methods for installing built-in parts, the installation of built-in parts is usually completed after the built-in parts are fixed to the inner wall of the oil tank by hot melting. Since the built-in parts are immersed in liquid oil for a long time, and the liquid oil shakes in the oil tank due to bumps and other reasons during use, the liquid oil will wash and corrode the built-in parts and their fusion seams, resulting in shaking, falling off, etc.

[0049] Based on this, the improved built-in component fixture disclosed in the present invention is also provided with a welding manipulator, which can quickly wrap a layer of welding strips on the outer ring of the fusion. This can protect the fusion seam. And the welding strip is fused with the molten part 1 and the molten part 2 at the same time, which can further increase the fixing strength between the two, thereby improving the firmness of the installation of the built-in component. In addition, by providing a number of heating ejectors, the uniformity of the hot melting of the welding strip can be improved, and it is also beneficial to increase the effective fusion area of ​​the welding strip and the butt fusion. Thereby, the welding firmness of the welding strip can be improved.

[0050] Further, the clamping component may also include a telescopic component (not shown in the figure) and a sensor 306. Here, the telescopic component is arranged on the limiter 302, and is located below the clamping portion 303. The built-in component 4 can push the telescopic component when it is installed on the clamping component. The sensor 306 is arranged on the limiter 302, and is located above and behind the telescopic component, and is used to detect the telescopic component to determine whether there is a built-in component 4 on the clamping component.

[0051] In some embodiments, the telescopic member can be a long rod passing through a spring. When the long rod is squeezed, the long rod as a whole retracts and compresses the spring; after the squeezing of the long rod is canceled, the long rod as a whole extends forward under the action of the spring until it is reset. When the built-in component 4 is fastened to the clamping portion 303, it will squeeze the telescopic member below the clamping portion 303, causing it to move backward as a whole for a distance. Then the sensor 306 located above and behind the telescopic member will detect that the long rod has been extended, that is, it will detect that the built-in component 4 has been installed in place.

[0052] In some embodiments, the clamping component may further include a second detection member 7 for detecting the center position of the second molten member to align the first molten member with the second molten member. Figure 1B As shown, the center of the melting piece 5 may have a through hole 501. Figure 3A and 3B As shown, the clamping portion 303 may be provided with a clamping groove 305 at a position corresponding to the through hole. At this time, the detection member 2 7 may be arranged in the clamping groove.

[0053] As an example, the detection part 2 7 can use an image collector. Then, based on the image of the molten part 2 collected by it, the center position of the molten part 2 is determined. Optionally, the detection part 2 7 can also use a photosensitive probe. A signal mark for detection by the detection part 2 7 can be set at the center position of the molten part 2. That is, the detection part 7 can assist the alignment of the molten part 1 5 and the molten part 2. After the molten part 1 5 is aligned with the molten part 2, the robot arm 1 will drive the mounting plate 2 to make the molten part 1 5 close to the molten part 2.

[0054] In some embodiments, the molten member heating mechanism 6 may include a moving driving member 601, a bottom plate 602, a rotating driving member 603, a rotating disk 604, and a heating plate 605. Figure 1B As shown, the moving driving member 601 is arranged on the mounting plate 2. The bottom plate 2 602 is arranged on the moving driving member 601. The rotating driving member 603 is arranged on the bottom plate 2 602. The turntable 604 is arranged at the output end of the rotating driving member 603. The rotation axis of the turntable 604 is perpendicular to the moving direction of the bottom plate 2 602. The heating plate 605 is swingably arranged on the turntable 604. Here, the space between the melting piece 1 5 and the melting piece 2 is defined as space 1, and the heating plate 605 extends into or out of space 1 after swinging.

[0055] Further, the molten piece heating mechanism 6 may further include a gear 1 606 and a swing arm 607. The gear 1 606 is disposed on the turntable 604 and is coaxial with the turntable 604. The swing arm 607 is rotatably disposed on the turntable 604. The rotation axis of the swing arm 607 may be parallel to the rotation axis of the turntable 604. The heating plate 605 follows the swing by being disposed on the swing arm 607. The swing arm 607 may have a tooth portion 608, and the tooth portion 608 is meshed with the gear 1 606. After the swing arm 607 swings, the heating plate 605 is located between the molten piece 1 5 and the molten piece 2 or is separated therefrom.

[0056] In this embodiment, the molten member heating mechanism 6 can be located on one side of the built-in member clamping mechanism 3. The moving driving member 601 can be a cylinder. The rotating driving member 603 can be a motor. The bottom plate 2 602 is driven to move by the cylinder. The motor is on the bottom plate 2 602. The turntable 604 is driven to rotate by the motor. A swing arm 607 is installed on the turntable 604, which can follow the turntable 604 in revolution and can rotate freely on the turntable 604. Then a gear 1 606 is installed. Gear 1 606 and the turntable 604 are driven to rotate together by the motor. Gear 1 606 meshes with the tooth 608 on the swing arm 607. Therefore, when the molten member 1 5 and the molten member 2 are spaced a certain distance apart, the cylinder can be started to make the heating plate 605 located at a plane position between the molten member 1 5 and the molten member 2. Then the motor is started, the turntable 604 rotates, and the swing arm 607 swings away from the turntable 604 driven by the gear 1 606. Finally, the heating plate 605 stops between the melting piece 1 5 and the melting piece 2. After that, the distance between the melting piece 1 5 and the melting piece 2 can be adjusted again, so that both surfaces of the melting piece 1 5 and the melting piece 2 are in contact with the heating plate 605 for heating. After the heating is completed, the motor can be reversed to reset.
