Description

Technical Field

[0001] The invention relates to the technical field of ultrasonic welding and hot riveting, in particular to integrated ultrasonic welding and hot riveting equipment for vehicle lamp parts. Background Art

[0002] Ultrasonic welding is a technology that uses mechanical vibrations generated by high-frequency vibrations to achieve welding. It is a very common welding method and is widely used in the welding and connection of materials such as plastics and metals. In ultrasonic welding, the joints of two or more materials are placed together and then welded using an ultrasonic welding head. The ultrasonic welding head transmits high-frequency vibrations to the materials to be welded, causing them to generate frictional heat, thereby softening the material surface and achieving a connection between the materials.

[0003] Hot riveting is a method of connecting rivets to workpieces using heat energy. It is done by transferring high temperature to the rivet, causing it to plasticize and form a strong connection with the workpiece. Hot riveting is suitable for connecting metal materials or joints between metal and non-metallic materials.

[0004] As the structure of headlights becomes more and more complex, more and more parts need to be ultrasonically welded from different angles. Different equipment and tooling need to be customized for welding, which is costly. In addition, in the process of welding curved surfaces, inaccurate positioning may occur. The welding angle cannot be perpendicular to the tangent direction of the curved surface, and the welding quality cannot be guaranteed.

[0005] Therefore, a device that can improve the welding efficiency of car lights and ensure the welding quality is needed to meet the needs. Summary of the Invention

[0006] The object of the present invention is to provide an integrated ultrasonic welding and hot riveting device for vehicle lamp parts to solve the problems raised in the above background technology.

[0007] In order to solve the above technical problems, the present invention provides the following technical solutions: an integrated ultrasonic welding and hot riveting equipment includes a frame, a workbench, a tool changing table, a manipulator, a welding assembly, a riveting assembly, and an assembly device. The workbench is fastened to the frame, the tool changing table is fastened to the frame, the manipulator is fastened to the frame, the welding assembly is fastened to the assembly device, the riveting assembly is fastened to the assembly device, the assembly device is clamped to the manipulator, a positioning hole is provided on the tool changing table, and a pin is provided on the assembly device, and the pin is inserted into the positioning hole.

[0008] The frame is the installation basis of each component and provides a good processing environment for each component. The workbench is used to place the workpiece, and the manipulator is used to drive the welding and riveting components to process the workpiece. In order to improve the processing efficiency, the manipulator can automatically change on the tool changing table through the set control program, and switch back and forth between the welding component and the riveting component to realize the integration of welding and riveting. In order to facilitate the switching between welding and riveting, the assembly device and the manipulator cooperate with each other and can be quickly disassembled and assembled. In order to ensure the accuracy of replacement, positioning holes are set on the tool changing table, and the pins on the assembly device cooperate with the positioning holes to automatically guide the changing action of the manipulator. There are many different welding components placed on the tool changing table, which can be automatically replaced by the manipulator according to processing needs.

[0009] Furthermore, the workbench includes a cabinet and a clamp. The cabinet is tightly connected to the frame, and the clamp is tightly connected to the cabinet. The clamp is provided in several groups.

[0010] The fixture can be replaced with different types according to the workpiece to be processed. The cabinet provides a stable installation base for the fixture. Setting up several groups of fixtures can process multiple workpieces at a time, thereby improving processing efficiency.

[0011] Furthermore, the manipulator includes a base, an arm body, and a connecting device. The base is tightly connected to the frame, the arm body is tightly connected to the base, the connecting device is transmission-connected to the arm body, and the connecting device is clamped to the assembly device.

[0012] The base is fixed on the frame to provide an installation foundation for the robot. The arm can move freely, thereby driving the connecting device to move together, and then driving the assembly device to move, so that the welding components and riveting components can move freely at the work station.

[0013] Furthermore, the welding assembly includes an ultrasonic generator, a transducer, a horn, a welding head, a fixing frame, and a heat dissipation device. The ultrasonic generator is electrically connected to the transducer, the transducer is firmly connected to the horn, the welding head is firmly connected to the horn, the transducer, the horn and the welding head are arranged in sequence along the fixing frame, the fixing frame is firmly connected to the assembly device, and the heat dissipation device is firmly connected to the fixing frame.

[0014] The ultrasonic generator converts the power supply voltage into ultrasonic frequency voltage. The transducer converts the ultrasonic frequency voltage from the ultrasonic generator into ultrasonic mechanical vibration of the same frequency through the inverse piezoelectric effect. The horn amplifies the mechanical vibration generated by the end of the transducer and transmits the vibration to the welding head. The fixing frame fixes the welding assembly on the assembly device for matching with the manipulator. When the welding head reaches a certain amplitude of high-frequency vibration, the ultrasonic energy is transmitted to the welding area through the upper weldment. Due to the large acoustic impedance at the welding area, that is, the interface between the two welds, local high temperature will be generated. Due to the poor thermal conductivity of plastic, heat cannot be dissipated in time and accumulates in the welding area, causing the contact surface of the two plastics to melt rapidly. After the manipulator applies a certain pressure, it fuses them into one. When the ultrasonic wave stops, the pressure is maintained for a few seconds to solidify and form, thus forming a strong molecular chain to achieve the purpose of welding. Ultrasonic welding melts the workpiece by driving the workpiece to vibrate and generate heat to fuse the two into one. Therefore, a large amount of heat will accumulate in the welding head. In order to prevent the welding head from overheating and damaging the workpiece, a heat sink is set on one side of the welding head for cooling.

[0015] Furthermore, an air flow channel is provided in the welding head, an air inlet of the air flow channel faces the heat dissipation device, and an air outlet of the air flow channel is provided on both sides of the welding head.

[0016] The heat dissipation device is connected to an external air source and cools the welding head by ejecting high-speed airflow. By setting an inverted Y-shaped air flow channel in the welding head, the airflow flows out through the air outlets on both sides of the welding head, which not only quickly reduces the temperature inside the welding head, but also cools the workpiece, accelerates the solidification of the welding point, and improves processing efficiency.

[0017] Furthermore, the riveting assembly includes a support plate, a heating element, and a riveting head. The support plate is fastened to the assembly device, the heating element is fastened to the support plate, and the riveting head is fastened to the heating element.

[0018] The support plate fixes the riveted assembly on the assembly device. The heating element provides heat for the hot rivet and transfers the heat to the riveting head. The riveting head melts the rivet and is pressed against the workpiece by the manipulator, applying a certain pressure to the rivet to fix it on the workpiece.

[0019] Furthermore, the welding assembly also includes a detection device, which is fastened to the fixed frame. The detection device includes a telescopic cylinder, a protective tube, a sliding rod, a spring, and a pressure sensor. The telescopic cylinder is fastened to the fixed frame, the protective tube is transmission-connected to the output end of the telescopic cylinder, the sliding rod is slidingly connected to the protective tube, the spring is sleeved on the sliding rod, the pressure sensor is fastened to the protective tube, the upper end of the sliding rod abuts against the pressure sensor, and the pressure sensor is electrically connected to the manipulator.

[0020] Because the workpiece being processed is a car light, there will be curved surfaces that need to be processed, and the automatic positioning of the robot will have certain errors. During welding, the welding head will not necessarily weld in a direction perpendicular to the tangent of the curved surface, and may weld at an angle. The welding quality cannot be guaranteed. After the robot drives the welding assembly to the processing position, the telescopic cylinder is activated to bring the detection device close to the workpiece. The sliding rod can slide up and down in the protective tube, and the spring supports the sliding rod. When the sliding rod abuts the workpiece, it will be subjected to the reaction force of the workpiece. The sliding rod slides upward, the spring is stretched, and the pressure sensor is subjected to pressure, giving an electrical signal to the telescopic cylinder. The telescopic cylinder stops working and starts to detect the curved surface.

[0021] Furthermore, an air guide channel is provided in the sliding rod, the air guide channel is connected to an external air source, and an air outlet of the air guide channel is located at the bottom end of the sliding rod.

[0022] If the welding assembly is not perpendicular to the tangent direction of the workpiece surface, when the air guide channel is connected to the air source, high-speed airflow will be ejected along the air outlet of the air guide channel to the surface of the workpiece and flow along the surface. At this time, the repulsive force fed back to the sliding rod is small, and the pressure on the pressure sensor is small. The pressure sensor sends an electrical signal to the robot to fine-tune the angle between the welding assembly and the workpiece. When the welding assembly is perpendicular to the tangent direction of the workpiece surface, the incident direction of the airflow is also perpendicular to the workpiece surface. At this time, the airflow will gather at the ejection port, and the repulsive force fed back to the sliding rod is large, and the pressure on the pressure sensor is large. Therefore, when the pressure on the pressure sensor is the largest, it indicates that the welding assembly is perpendicular to the tangent direction of the workpiece surface, the angle is adjusted in place, the telescopic cylinder is actuated, the detection device is retracted, and the robot drives the welding assembly for processing. The outflowing airflow can also remove debris on the surface of the workpiece and improve the welding quality.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are as follows: the present invention is based on an ultrasonic welding structure, a hot riveting structure and a control system of a manipulator, integrating ultrasonic welding and hot riveting together, and can use ultrasonic welding and hot riveting at different angles. The welding direction is flexible and can be applied to spot welding at different angles. Parts that are spot welded at different angles only need to replace the welding head, and there is no need to customize equipment to meet welding requirements, thereby reducing costs. The curved surface of the workpiece is detected by a detection device, and the repulsive force of the airflow on the sliding rod is used to determine whether the welding assembly is perpendicular to the tangent direction of the curved surface, and the angle between the welding assembly and the workpiece is adjusted to ensure processing quality. In addition, the airflow can remove debris on the surface of the workpiece, thereby improving welding quality. BRIEF DESCRIPTION OF THE DRAWINGS

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] The present invention provides a technical solution:

[0036] like Figure 1 、 Figure 2 、 Figure 4As shown, the integrated ultrasonic welding and hot riveting equipment includes a frame 1, a workbench 2, a tool changing table 3, a manipulator 4, a welding assembly 5, a riveting assembly 6, and an assembly device 7. The workbench 2 is fastened to the frame 1, the tool changing table 3 is fastened to the frame 1, the manipulator 4 is fastened to the frame 1, the welding assembly 5 is fastened to the assembly device 7, the riveting assembly 6 is fastened to the assembly device 7, and the assembly device 7 is clamped with the manipulator 4. A positioning hole 31 is provided on the tool changing table 3, and a pin is provided on the assembly device 7, which is inserted into the positioning hole 31.

[0037] The frame 1 is the installation base of each component and provides a good processing environment for each component. The workbench 2 is used to place the workpiece, and the manipulator 4 is used to drive the welding component 5 and the riveting component 6 to process the workpiece. In order to improve the processing efficiency, the manipulator 4 can automatically change on the tool changing table 3 through a set control program, and switch back and forth between the welding component 5 and the riveting component 6 to realize the integration of welding and riveting. In order to facilitate the switching between welding and riveting, the assembly device 7 and the manipulator 4 cooperate with each other and can be quickly disassembled and assembled. In order to ensure the accuracy of replacement, by setting a positioning hole 31 on the tool changing table 3, the pin on the assembly device 7 cooperates with the positioning hole 31, which can automatically guide the changing action of the manipulator 4. A variety of different welding components 5 are placed on the tool changing table 3, which can be automatically replaced by the manipulator 4 according to processing needs.

[0038] like Figure 2 As shown, the workbench 2 includes a cabinet 21 and a clamp 22 . The cabinet 21 is firmly connected to the frame 1 , and the clamp 22 is firmly connected to the cabinet 21 . There are several groups of clamps 22 .

[0039] The fixture 22 can be replaced with different types according to the workpiece to be processed. The cabinet 21 provides a stable installation base for the fixture 22. Setting up several groups of fixtures 22 can process multiple workpieces at a time, thereby improving processing efficiency.

[0040] like Figure 2 、 Figure 3 As shown, the manipulator 4 includes a base 41, an arm 42, and a connecting device 43. The base 41 is fastened to the frame 1, the arm 42 is fastened to the base 41, the connecting device 43 is transmission-connected to the arm 42, and the connecting device 43 is clamped to the assembly device 7.

[0041] The base 41 is fixed on the frame 1 to provide an installation foundation for the manipulator 4. The arm 42 can move freely, thereby driving the connecting device 43 to move together, and then driving the assembly device 7 to move, so that the welding component 5 and the riveting component 6 can move freely at the work station.

[0042] like Figure 3 、 Figure 5As shown, the welding assembly 5 includes an ultrasonic generator 51, a transducer 52, a horn 53, a welding head 54, a fixing frame 55, and a heat dissipation device 56. The ultrasonic generator 51 is electrically connected to the transducer 52, the transducer 52 is fastened to the horn 53, the welding head 54 is fastened to the horn 53, the transducer 52, the horn 53 and the welding head 54 are arranged in sequence along the fixing frame 55, the fixing frame 55 is fastened to the assembly device 7, and the heat dissipation device 56 is fastened to the fixing frame 55.

[0043] The ultrasonic generator 51 converts the power supply voltage into an ultrasonic frequency voltage. The transducer 52 converts the ultrasonic frequency voltage from the ultrasonic generator 51 into ultrasonic mechanical vibration of the same frequency through the inverse piezoelectric effect. The horn 53 amplifies the mechanical vibration generated at the end of the transducer 52 and transmits the vibration to the welding head 54. The fixing frame 55 fixes the welding assembly 5 on the assembly device 7 for matching with the manipulator 4. When the welding head 54 reaches a high-frequency vibration of a certain amplitude, the ultrasonic energy is transmitted to the welding area through the upper weldment. Since the welding area, that is, the interface between the two welds, has a large acoustic impedance, local high temperature will be generated. In addition, due to the plastic Due to poor thermal conductivity, heat cannot be dissipated in time and accumulates in the welding area, causing the contact surfaces of the two plastics to melt rapidly. After the robot 4 applies a certain amount of pressure, it fuses them into one. When the ultrasonic wave stops working, the pressure is allowed to continue for a few seconds to solidify and form, thus forming a strong molecular chain to achieve the purpose of welding. Ultrasonic welding melts the workpiece by generating heat through vibration and friction of the workpiece, so that the two are fused into one. Therefore, a large amount of heat will accumulate on the welding head 54. In order to prevent the welding head 54 from overheating and damaging the workpiece, a heat dissipation device 56 is provided on one side of the welding head 54 for cooling.

[0044] like Figure 5 、 Figure 7 As shown, an air channel 541 is provided in the welding head 54 , an air inlet of the air channel 541 faces the heat dissipation device 56 , and an air outlet of the air channel 541 is provided on both sides of the welding head 54 .

[0045] The heat dissipation device 56 is connected to an external air source, and cools the welding head 54 by ejecting high-speed airflow. By setting an inverted Y-shaped air flow channel 541 in the welding head 54, the airflow flows out through the air outlets on both sides of the welding head 54, which not only quickly reduces the temperature inside the welding head 54, but also cools the workpiece, accelerates the solidification of the welding point, and improves the processing efficiency.

[0046] like Figure 6 As shown, the riveting assembly 6 includes a support plate 61 , a heating element 62 , and a riveting head 63 . The support plate 61 is fastened to the assembly device 7 , the heating element 62 is fastened to the support plate 61 , and the riveting head 63 is fastened to the heating element 62 .

[0047] The support plate 61 fixes the riveting assembly 6 on the assembly device 7, and the heating element 62 provides heat for hot riveting and transfers the heat to the riveting head 63. The riveting head 63 melts the rivet and is pressed onto the workpiece under the drive of the manipulator 4, applying a certain pressure to the rivet to fix the rivet on the workpiece.

[0048] like Figure 5 、 Figure 8 As shown, the welding assembly 5 also includes a detection device 57, which is fastened to the fixed frame 55. The detection device 57 includes a telescopic cylinder 571, a protective tube 572, a sliding rod 573, a spring 574, and a pressure sensor 575. The telescopic cylinder 571 is fastened to the fixed frame 55, the protective tube 572 is transmission-connected to the output end of the telescopic cylinder 571, the sliding rod 573 is slidingly connected to the protective tube 572, the spring 574 is sleeved on the sliding rod 573, the pressure sensor 575 is fastened to the protective tube 572, the upper end of the sliding rod 573 abuts against the pressure sensor 575, and the pressure sensor 575 is electrically connected to the manipulator 4.

[0049] Because the workpiece being processed is a car lamp, there will be a curved surface that needs to be processed, and the automatic positioning of the robot 4 will have a certain error. During welding, the welding head 54 will not necessarily weld in a direction perpendicular to the tangent of the curved surface, and may weld at an angle, and the welding quality cannot be guaranteed. After the robot 4 drives the welding assembly 5 to the processing position, the telescopic cylinder 571 is activated to bring the detection device 57 close to the workpiece, and the sliding rod 573 can slide up and down in the protective tube 572. The spring 574 supports the sliding rod 573. When the sliding rod 573 abuts the workpiece, it will be subjected to the reaction force of the workpiece. The sliding rod 573 slides upward, the spring 574 is stretched, and the pressure sensor 575 is subjected to pressure, giving an electrical signal to the telescopic cylinder 571. The telescopic cylinder 571 stops working and starts to detect the curved surface.

[0050] like Figure 8 As shown, an air guide channel is provided in the sliding rod 573 , the air guide channel is connected to an external air source, and an air outlet of the air guide channel is located at the bottom end of the sliding rod 573 .

[0051] If the welding assembly 5 is not perpendicular to the tangential direction of the workpiece surface, when the air guide channel is connected to the air source, the high-speed airflow will be sprayed onto the workpiece surface along the air outlet of the air guide channel and flow along the surface. At this time, the repulsive force fed back to the sliding rod 573 is small, and the pressure on the pressure sensor 575 is small. The pressure sensor 575 sends an electrical signal to the manipulator 4 to fine-tune the angle between the welding assembly 5 and the workpiece. When the welding assembly 5 is perpendicular to the tangential direction of the workpiece surface, the incident direction of the airflow is also perpendicular to the workpiece surface. At this time, the airflow will gather at the injection port, and the repulsive force fed back to the sliding rod 573 is large, and the pressure on the pressure sensor 575 is large. Therefore, when the pressure on the pressure sensor 575 is the maximum, it indicates that the welding assembly 5 is perpendicular to the tangential direction of the workpiece surface. The angle is adjusted to the right position, the telescopic cylinder 571 is actuated, the detection device 57 is retracted, and the manipulator 4 drives the welding assembly 5 for processing. The outflowing airflow can also remove debris on the surface of the workpiece and improve the welding quality.

[0052] The working principle of the present invention is as follows: first, the workpiece to be processed is placed on the workbench 2 and clamped with the clamp 22. Then, the manipulator 4 drives the welding assembly 5 to move to the top of the workpiece along the set program to prepare for welding. When it is necessary to weld a curved surface, the contact angle between the welding assembly 5 and the workpiece is detected by the detection device 57, and the pressure change is fed back to the pressure sensor 575 through the sliding rod 573. When the welding assembly 5 is perpendicular to the tangent direction of the workpiece curved surface, the incident direction of the airflow is also perpendicular to the workpiece curved surface. At this time, the airflow will gather at the injection port and be fed back to the pressure sensor 575. The repulsive force of the sliding rod 573 is large, and the pressure on the pressure sensor 575 is large. Therefore, when the pressure on the pressure sensor 575 is maximum, it indicates that the welding assembly 5 is perpendicular to the tangent direction of the workpiece surface, the angle is adjusted to the right position, the telescopic cylinder 571 is actuated, the detection device 57 is retracted, and the manipulator 4 drives the welding assembly 5 for processing. After the welding process is completed, the manipulator 4 drives the welding assembly 5 to leave the processing position and switch to the riveting assembly 6 through the assembly device 7 on the tool changing table 3 to perform riveting processing on the workpiece. After the processing is completed, the clamp 22 is released and the workpiece is taken out.
