Technical Field
[0001] The present invention relates to the technical field of assembly devices, and specifically, it is an assembly device for a vehicle instrument panel with an auxiliary positioning function. Background Art
[0002] The instrument panel is usually located at the center console position in front of the driver and passengers, integrating various display and control elements, such as a speedometer, a tachometer, a fuel gauge, a water temperature gauge, as well as various warning indicator lights and switch buttons. These elements provide real-time feedback on the vehicle's operating status to the driver and allow them to perform necessary operations, such as adjusting the in-vehicle temperature, volume, and switching driving modes, etc. With the continuous development of the automotive industry and automation technology, as an important part of the vehicle interior, the assembly quality and efficiency of the instrument panel have an important impact on the overall performance and manufacturing cost of the vehicle.
[0003] During the assembly process of the instrument panel, fixtures are required for clamping and positioning to ensure the stability and reliability of the assembly. In the existing instrument panel assembly devices, shaking is extremely likely to occur during the assembly process, making it difficult to ensure the consistency of the assembly accuracy. Summary of the Invention
[0004] The purpose of the present invention is to provide an assembly device for a vehicle instrument panel with an auxiliary positioning function to solve the problems raised in the prior art.
[0005] To achieve the above purpose, the present invention provides the following technical solution: An assembly device for a vehicle instrument panel with an auxiliary positioning function, including a negative pressure system, a control system, and a manipulator. The assembly device includes a table board, on which a slide rail is provided, a sliding seat is slidably installed on the slide rail, a fixed seat is installed on one side of the sliding seat, a driving motor is installed on the sliding seat, a rotating plate is installed on the output shaft of the driving motor, several contact plates are installed on the rotating plate, a rotating motor is installed on the fixed seat, a following plate is installed on the output shaft of the rotating motor, and several positioning plates are installed on the following plate. The contact plates and the positioning plates are used for positioning the instrument panel.
[0006] The fixed seat is arranged on the table board. A loading groove is provided in the middle of the following plate, and the shape of the loading groove is adapted to the shape of the instrument panel. Several sliding grooves are provided on the following plate outside the loading groove, and several positioning plates are respectively slidably installed in several sliding grooves. A first spring is connected between the positioning plate and the following plate, and the first spring is located in the sliding groove and is electrically connected to the control system.
[0007] An elastic membrane is connected between two adjacent positioning plates. The elastic membrane is made of an elastic material, one end of the elastic membrane is arranged on the following plate, and the elastic membrane wraps the instrument panel.
[0008] A number of suction cup holes are provided on the elastic membrane, and suction cups are installed in each of the number of suction cup holes. The suction cups are connected to a negative pressure system through pipelines.
[0009] The contact plate is hollow inside. A through groove is provided on one side of the contact plate. A flexible membrane is arranged in the through groove. Magnetorheological fluid and a coil are arranged in the contact plate. The magnetorheological fluid is in contact with the coil and the inner side of the flexible membrane respectively. The outer side of the flexible membrane is in contact with the instrument panel. Both ends of the coil are electrically connected to a control system.
[0010] A number of the contact plates are all installed on a rotating plate. A shielding membrane is connected between the number of contact plates and the rotating plate. The shielding membrane is connected to the negative pressure system through a pipeline.
[0011] Press the start button on the control panel, and the assembly device starts. The manipulator moves the instrument panel to the position between the rotating plate and the follower plate. The vision camera identifies the shape and size of the instrument panel and feeds the data back to the control system. The control system obtains the three-dimensional model of the instrument panel through calculation and drawing. Then, the control system energizes the first spring. After the first spring is energized, a mutually attractive magnetic field is generated in each turn, and this magnetic field causes the first spring to shorten as a whole. The first spring pulls the positioning plate to move outwards, so that the distance between two opposite positioning plates can accommodate the instrument panel. When the first spring is energized for a set time, the control system inserts one end of the instrument panel into the loading groove in the middle of the follower plate through the manipulator. The manipulator feeds the in-place signal of the instrument panel back to the control system. The control system cuts off the power supply of the first spring. The first spring pushes the positioning plate to move inwards under its own elastic force. The positioning plate clamps and positions the instrument panel. The elastic membrane between two adjacent positioning plates is in contact with the instrument panel, and the suction cups on the elastic membrane are in contact with the instrument panel synchronously. The control system makes the suction cups in contact with the instrument panel in a negative pressure state through the negative pressure system according to the three-dimensional model data of the instrument panel, so that the suction cups adsorb and position the instrument panel. Therefore, through the clamping and positioning of the positioning plate and the adsorption and positioning of the suction cups, one end of the instrument panel can be fully positioned to ensure normal assembly work.
[0012] After one end of the instrument panel is inserted into the loading groove through the manipulator, the control system drives the sliding seat to move towards the other end of the instrument panel close to it through the transverse electric cylinder. The sliding seat drives the driving motor, the rotating plate and the contact plate to move towards the other end of the instrument panel close to it, so that the flexible membrane on the contact plate contacts the instrument panel. The instrument panel squeezes the flexible membrane, and the flexible membrane and the magnetorheological fluid in the contact plate are squeezed and flow. At this time, the flexible membrane is closely attached to the surface of the instrument panel. When the flexible film is in close contact with the surface of the instrument panel, the displacement sensor in the horizontal electric cylinder feeds the displacement data back to the control system. The control system connects both ends of the coil to the circuit, and the coil generates a magnetic field to convert the magnetorheological fluid from a liquid state to a solid state, so as to ensure that the flexible film adheres to the surface of the instrument panel. After that, the control system extracts the air inside the shielding film through the negative pressure system. At this time, the instrument panel will be adsorbed on the flexible film, realizing the adsorption positioning of the other end of the instrument panel, and the flexible film can adapt to the shape of the other end of the instrument panel, further improving the clamping effect.
[0013] After both ends of the instrument panel are positioned, the driving motor and the rotating motor drive the rotating plate and the follower plate to rotate respectively. The rotating plate and the follower plate synchronously drive the positioned instrument panel to rotate a certain angle, avoiding the deviation of the instrument panel during the rotation process, making the position to be assembled face the staff, so as to facilitate the assembly operation and improve the assembly efficiency.
[0014] After the assembly is completed, the manipulator clamps and positions the assembled instrument panel. Then, the control system energizes the first spring, causing the first spring to pull the positioning plate to move away from the instrument panel, and making the suction cups in the normal pressure state through the negative pressure system, so that the suction cups cannot adsorb and position the instrument panel; the control system simultaneously cuts off the power supply of the coil. After the magnetic field of the coil disappears, the magnetorheological fluid changes from the original solid state to the liquid state, and can no longer position the instrument panel, and makes the inside of the shielding film in the normal pressure state through the negative pressure system. After that, the horizontal electric cylinder drives the driving motor, the rotating plate, the contact plate, etc. to move to the right through the sliding seat. Finally, the manipulator takes out the assembled instrument panel.
[0015] A bracket is arranged above the table board, a vision camera is installed on the bracket, the vision camera is electrically connected to the control system, and the vision camera performs auxiliary positioning on the instrument panel.
[0016] The sliding seat is connected to the telescopic rod of the horizontal electric cylinder, and the horizontal electric cylinder is installed on the table board; The horizontal electric cylinder, the driving motor and the rotating motor are all internally provided with an encoder, a pressure sensor and a displacement sensor, and the encoder, the pressure sensor and the displacement sensor are all electrically connected to the control system.
[0017] A control panel is arranged on the table board, and the control system is arranged inside the control panel.
[0018] Compared with the prior art, the beneficial effects of the present invention are: 1. Position the instrument panel through the cooperation of the positioning plate, vision camera and suction cup to prevent the instrument panel from shaking during assembly. The control system inserts one end of the instrument panel into the loading slot in the middle of the following plate through the manipulator. The manipulator feeds back the in-place signal of the instrument panel to the control system. The control system cuts off the power supply of the first spring. Under the action of its own elastic force, the first spring pushes the positioning plate to move inwards. The positioning plate clamps and positions the instrument panel. The elastic film between two adjacent positioning plates contacts the instrument panel, and the suction cups on the elastic film contact the instrument panel synchronously. According to the three-dimensional model data of the instrument panel, the control system makes the suction cups in contact with the instrument panel in a negative pressure state through the negative pressure system, so that the suction cups adsorb and position the instrument panel. Therefore, through the clamping and positioning of the positioning plate and the adsorption and positioning of the suction cups, one end of the instrument panel can be fully positioned, ensuring normal assembly work and preventing the instrument panel from shaking during assembly.
[0019] 2. Position the instrument panel through the cooperation of the flexible film, magnetorheological fluid and negative pressure system to further improve the stability of the instrument panel. The displacement sensor in the horizontal electric cylinder feeds back the displacement data to the control system. The control system connects both ends of the coil to the circuit. The coil generates a magnetic field to turn the magnetorheological fluid from a liquid state to a solid state, ensuring that the flexible film adheres to the surface of the instrument panel. Then, the control system extracts the air in the shielding film outwards through the negative pressure system. At this time, the instrument panel will be adsorbed on the flexible film, realizing the adsorption and positioning of the other end of the instrument panel. Moreover, the flexible film can adapt to the shape of the other end of the instrument panel, further improving the clamping effect and the stability of the instrument panel.
[0020] 3. The double motors drive the instrument panel to flip synchronously to prevent the instrument panel from shifting. The driving motor and the rotating motor drive the rotating plate and the following plate to rotate respectively. The rotating plate and the following plate drive the positioned instrument panel to rotate a certain angle synchronously, preventing the instrument panel from shifting during rotation, making the position to be assembled face the operator, facilitating the assembly operation and improving the assembly efficiency.

[0025] The fixed seat 13 is arranged on the table board 11. A load-carrying groove is provided in the middle of the following plate 31, and the load-carrying groove is adapted to the outer shape of the instrument panel. The load-carrying groove positions the instrument panel. A plurality of sliding grooves are provided on the following plate 31 outside the load-carrying groove, and a plurality of positioning plates 32 are respectively slidably installed in the plurality of sliding grooves. The plurality of positioning plates 32 slide in the sliding grooves. A first spring 33 is connected between the positioning plate 32 and the following plate 31. The first spring 33 is located in the sliding groove, and the first spring 33 is electrically connected to the control system.
[0026] An elastic membrane 34 is connected between two adjacent positioning plates 32. The elastic membrane 34 is made of an elastic material. One end of the elastic membrane 34 is arranged on the follower plate 31. The elastic membrane 34 wraps the instrument panel. A number of suction cup holes are arranged on the elastic membrane 34. Suction cups 331 are installed in the number of suction cup holes. The suction cups 331 are connected to a negative pressure system through pipelines. By contacting the surface of the instrument panel through the elastic membrane 34, and the elastic membrane 34 can adapt to the shape of the instrument panel, and then the instrument panel is adsorbed and positioned through the suction cups 331.
[0027] The contact plate 22 is hollow inside. A through groove is arranged on one side of the contact plate 22. A flexible membrane 23 is arranged in the through groove. Magnetorheological fluid and a coil 24 are arranged in the contact plate 22. The magnetorheological fluid is in contact with the coil 24 and the inner side of the flexible membrane 23 respectively. The outer side of the flexible membrane 23 is in contact with the instrument panel. Both ends of the coil 24 are electrically connected to a control system. A number of contact plates 22 are all installed on the rotating plate 21. A shielding membrane 211 is connected between the number of contact plates 22 and the rotating plate 21. The shielding membrane 211 is connected to the negative pressure system through a pipeline. When the coil 24 is powered off, the magnetorheological fluid is in a liquid state; when the coil 24 is powered on, the magnetorheological fluid is affected by the magnetic field of the coil 24 and changes from a liquid state to a solid state to adapt to the shape of the instrument panel, and then the instrument panel is positioned.
[0028] The sliding seat 12 is connected to the telescopic rod of a transverse electric cylinder 14. The transverse electric cylinder 14 is installed on the table board 11; the transverse electric cylinder 14, the driving motor 2 and the rotating motor 3 are all internally provided with encoders, pressure sensors and displacement sensors. The encoders, pressure sensors and displacement sensors are all electrically connected to the control system.
[0029] Working principle: Press the start button on the control panel 1, and the assembly device starts. The instrument panel is moved to the position between the rotating plate 21 and the follower plate 31 through the manipulator. The vision camera 15 identifies the shape and size of the instrument panel and feeds the data back to the control system. The control system obtains the three-dimensional model of the instrument panel through calculation and drawing. Then, the control system powers on the first spring 33. After the first spring 33 is powered on, a magnetic field that attracts each other is generated between each turn. This magnetic field causes the first spring 33 to shorten as a whole. The first spring 33 pulls the positioning plate 32 to move outward, so that the distance between two opposite positioning plates 32 can accommodate the instrument panel; After the first spring 33 is energized for a set time, the control system inserts one end of the instrument panel into the loading slot in the middle of the following plate 31 through a manipulator. The manipulator feeds back the in-place signal of the instrument panel to the control system. The control system cuts off the power supply to the first spring 33. The first spring 33 pushes the positioning plate 32 to move inward under its own elastic force. The positioning plate 32 clamps and positions the instrument panel. The elastic membrane 34 between two adjacent positioning plates 32 contacts the instrument panel, and the suction cups 331 on the elastic membrane 34 contact the instrument panel synchronously. The control system, according to the three-dimensional model data of the instrument panel, makes the suction cups 331 in contact with the instrument panel in a negative pressure state through a negative pressure system, so that the suction cups 331 adsorb and position the instrument panel. Therefore, through the clamping and positioning of the positioning plate 32 and the adsorption and positioning of the suction cups 331, one end of the instrument panel can be fully positioned to ensure normal assembly work.
[0030] After inserting one end of the instrument panel into the loading slot through the manipulator, the control system drives the sliding seat 12 to move closer to the other end of the instrument panel through the transverse electric cylinder 14. The sliding seat 12 drives the drive motor 2, the rotating plate 21 and the contact plate 22 to move closer to the other end of the instrument panel, so that the flexible membrane 23 on the contact plate 22 contacts the instrument panel. The instrument panel squeezes the flexible membrane 23, and the magnetorheological fluid in the flexible membrane 23 and the contact plate 22 is squeezed and flows. At this time, the flexible membrane 23 closely adheres to the surface of the instrument panel. When the flexible membrane 23 closely adheres to the surface of the instrument panel, the displacement sensor in the transverse electric cylinder 14 feeds back the displacement data to the control system. The control system connects both ends of the coil 24 to the circuit. The coil 24 generates a magnetic field to turn the magnetorheological fluid from a liquid state to a solid state to ensure that the flexible membrane 23 always adheres to the instrument panel. Then, the control system extracts the air in the shielding membrane 211 outward through the negative pressure system. At this time, the instrument panel will be adsorbed on the flexible membrane 23, realizing the adsorption and positioning of the other end of the instrument panel, and the flexible membrane 23 can adapt to the shape of the other end of the instrument panel, further improving the clamping effect.
[0031] After both ends of the instrument panel are positioned, the drive motor 2 and the rotating motor 3 drive the rotating plate 21 and the following plate 31 to rotate respectively. The rotating plate 21 and the following plate 31 synchronously drive the positioned instrument panel to rotate a certain angle, avoiding the deviation of the instrument panel during rotation, making the position to be assembled face the staff, so as to facilitate the assembly operation and improve the assembly efficiency.
[0032] After assembly, the manipulator clamps and positions the assembled instrument panel. Then, the control system energizes the first spring 33, causing the first spring 33 to pull the positioning plate 32 to move away from the instrument panel side, and through the negative pressure system, the suction cups 331 are all in the normal pressure state, so that the suction cups 331 cannot adsorb and position the instrument panel; the control system simultaneously de-energizes the coil 24. After the magnetic field of the coil 24 disappears, the magnetorheological fluid changes from the original solid state to the liquid state, and will no longer be able to position the instrument panel, and through the negative pressure system, the inside of the shielding film 211 is in the normal pressure state. Then, the horizontal electric cylinder 14 drives the driving motor 2, the rotating plate 21, the contact plate 22, etc. to move to the right through the sliding seat 12. Finally, the manipulator takes out the assembled instrument panel.

Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting.
