Description

Technical Field

[0001] This application relates to the technical field of automotive parts assembly, and in particular to assembly equipment and assembly methods for automotive handle spring supports. Background Technology

[0002] With the continuous development of the automotive industry, higher requirements are being placed on the production efficiency and assembly precision of automotive parts. As an important external operating component of a vehicle, the door handle has a complex internal structure, especially the spring support part, which undertakes the important functions of rebound and positioning.

[0003] In related technologies, see Figures 1-2 A car handle spring support includes a base 200. A protrusion 230 is formed on the lower side of the base 200 along the Z-direction. A snap-fit ​​groove 210 is also formed on the base 200 along the Z-direction, penetrating the protrusion 230. An elastic clip 500 is installed inside the snap-fit ​​groove 210 from top to bottom along the Z-direction, with two clips 500 respectively embedded in the inner wall of the snap-fit ​​groove 210. A mounting groove 220 is provided on the other side of the snap-fit ​​groove 210 along the X-axis. A spring housing 300 is disposed within the mounting groove 220. A positioning strip 310 is formed on the outer side of the spring housing 300. The length direction of the positioning strip 310 is parallel to the Y-direction, and the length of the positioning strip 310 is shorter than the axial length of the spring housing 300. One side of the positioning strip 310 is flush with one end face of the spring housing 300. A ring spring 400 is embedded within the spring housing 300. One end of the ring spring 400 is bent outward along the X direction to form a bent portion 410, which is embedded in the base 200 along the X direction. The other end of the ring spring 400 is bent to form a fixing portion 420. A groove 320 is formed inside the spring housing 300. When the bent portion 410 is embedded in the base 200, the fixing portion 420 is embedded in the groove 320. A mounting hole 240 is also formed on the base 200. A positioning shaft 600 is inserted through the mounting hole 240. The axis of the positioning shaft 600 is parallel to the Y direction. The positioning shaft 600 passes through the base 200 and the spring housing 300 along its own axis, thereby fixing the spring housing 300 relatively on the base 200 along the X direction. The positioning shaft 600 and the spring housing 300 are coaxially arranged.

[0004] Traditional handle spring supports, due to their complex structure, are usually assembled manually or with semi-automated equipment, which is not only inefficient but also makes it difficult to guarantee assembly consistency and reliability. Summary of the Invention

[0005] To achieve automated assembly and improve assembly efficiency, this application provides assembly equipment and assembly method for automotive handle spring supports.

[0006] The assembly equipment and assembly method for automotive handle spring supports provided in this application adopt the following technical solution:

[0007] An assembly device for automotive handle spring supports includes: a frame; a first turntable, horizontally mounted on the frame and rotating relative to the frame about its own axis; a first positioning assembly, mounted on the first turntable, for positioning the spring housing, the ring spring, and the positioning shaft, wherein multiple first positioning assemblies are arranged circumferentially around the axis of the first turntable, forming multiple workstations; a first assembly device, mounted on the circumference or upper side of the first turntable, for assembling the spring housing and the ring spring; and a second turntable, horizontally mounted on the frame and rotating relative to the frame about its own axis; and a second... A positioning assembly, mounted on the second turntable, is used to position the base, spring housing, and positioning shaft. Multiple positioning assemblies are arranged in a circumferential array around the second turntable, forming multiple workstations. A second assembly device, mounted on the circumference or upper side of the second turntable, is used to assemble the base and elastic clamp, the base and spring housing, and the base and positioning shaft at different workstations. A transfer device, mounted on the frame, is used to move the spring housing and positioning shaft with an annular spring mounted on the first positioning assembly at the corresponding workstation on the first turntable to the second positioning assembly at the corresponding workstation on the second turntable. A turntable drive device drives the first and second turntables to rotate around their respective axes. A feeding device conveys the base, elastic clamp, spring housing, annular spring, and positioning shaft to the first positioning assembly or the second positioning assembly at the corresponding workstation.

[0008] By adopting the above technical solution, and by setting up a first turntable and a second turntable, combined with multiple first positioning components and second positioning components, precise division of labor and positioning of each component of the automotive handle spring support is achieved. The turntable structure drives each component to flow sequentially to different workstations, and cooperates with the first assembly device and the second assembly device to realize the automatic assembly of the spring shell and the ring spring, the base and the elastic clip, the base and the spring shell, and the positioning shaft. At the same time, the transfer device set up enables the intermediate parts (the spring shell with the ring spring and the positioning shaft) between the first turntable and the second turntable to be smoothly transferred, opening up the entire assembly process, realizing a high degree of structural integration and automation, and effectively improving assembly efficiency and consistency.

[0009] Preferably, the peripheral stations of the first turntable include a spring housing loading station, a ring spring loading station, a positioning shaft loading station, and a transfer station. The first assembly device is disposed on the upper side of the first turntable, and the first assembly device is disposed corresponding to the positioning shaft loading station.

[0010] By adopting the above technical solution, by sequentially arranging the spring housing, ring spring, and positioning shaft loading stations and transfer stations around the first turntable, the assembly process of the spring housing and ring spring is completely closed on the first turntable; the first assembly device is set on the first turntable, which can complete the combination of the spring housing and ring spring while loading the positioning shaft, which facilitates subsequent transfer, forms the first stage sub-component, and improves the station utilization rate and assembly cycle.

[0011] Preferably, the second turntable includes a base loading station, an elastic clip loading station, a placement station corresponding to the transfer station, an assembly station for the base and elastic clip, and an assembly station for the base and spring housing.

[0012] By adopting the above technical solution, the second turntable is circumferentially arranged with loading stations for the base and elastic clamps, as well as assembly stations, and a placement station corresponding to the transfer station is reserved to ensure that the entire process from loading to final assembly of the components is completed in a closed loop on the second turntable. Through station rotation, the base is installed, the spring shell and positioning shaft are received, and the assembly of the entire support is finally completed, improving the overall collaboration efficiency and station reusability.

[0013] Preferably, it also includes a control device, wherein the frame is provided with a plurality of position detection components for detecting the position of each component of the car handle spring support, any one of the position detection components is electrically connected to the control device, and each drive unit of the drive device, the feeding device, the first assembly device and the second assembly device is electrically connected to the control device.

[0014] By adopting the above technical solution and setting up control devices and position detection components, real-time control and status feedback of the first and second turntables can be achieved, ensuring the correct positioning of components at each workstation and the accurate execution of the assembly sequence; all drive units are electrically connected to the control device to ensure smooth transmission of information commands, possess strong automatic control capabilities, and ensure the safety and stability of system operation.

[0015] Preferably, the second assembly device includes a third assembly component for assembling the positioning shaft and the spring housing. The third assembly component is disposed on the upper side of the second turntable and is disposed corresponding to the assembly station of the positioning shaft and the spring housing.

[0016] By adopting the above technical solution, the positioning shaft and the base can be assembled immediately after the base and spring housing are assembled, thereby achieving rapid assembly of the support.

[0017] Preferably, a material unloading station is also provided on the periphery of the second turntable, and a slide rail is also provided on the frame. The slide rail extends out of the frame and is inclined downwards to the outside of the frame. The slide rail corresponds to the material unloading station. The frame is also provided with a material unloading device for moving the assembled car handle spring support onto the slide rail.

[0018] By adopting the above technical solution, setting up a material unloading station around the second turntable and an inclined slide rail on the frame, the finished product can be smoothly unloaded after assembly. The unloading device can accurately place the product onto the slide rail, allowing it to slide out of the frame automatically. The whole process does not require manual intervention, effectively improving the degree of automation and reducing manpower input.

[0019] Preferably, the second assembly device further includes a second assembly assembly for assembling the spring housing and the base. The second assembly assembly is located outside the assembly station of the base and the spring housing on the second turntable. A torsion mechanism for torsion of the ring spring is also provided outside the assembly station of the base and the spring housing.

[0020] By adopting the above technical solution and setting the second assembly component, the spring shell can be accurately inserted into the base; in conjunction with the torsion mechanism, the ring spring is rotated and adjusted so that its bent part faces the correct installation direction, thereby facilitating its movement and embedding into the base mounting slot, ensuring the relative position of the spring shell and the base, creating conditions for the subsequent insertion of the positioning shaft, and improving the overall assembly success rate and mechanical fit accuracy.

[0021] Preferably, the torsion mechanism includes a lateral telescopic cylinder, the piston rod of the lateral telescopic cylinder extending in the direction of extension and retraction pointing towards the center of the second turntable, a rotary motor fixed to the end of the piston rod of the lateral telescopic cylinder, a rotary shaft coaxially fixed on the output shaft of the rotary motor, an embedding groove for embedding the bent part provided on the side of the rotary shaft away from the rotary motor, the embedding groove being open on the side away from the rotary motor, and the embedding groove penetrating the rotary shaft in any radial direction.

[0022] By adopting the above technical solution, when the second positioning component moves to the assembly station of the base and the spring shell, the piston rod of the transverse telescopic cylinder extends, so that the rotating shaft of the rotary motor corresponds to the second positioning component. When the second assembly device assembles the spring shell and the base, the spring shell passes through the rotating shaft, and the bent part enters the embedding groove from one side. The rotary motor drives the rotating shaft to rotate 180 degrees, and the bent part faces the mounting groove. The second assembly device continues to drive the spring shell to move until it is embedded in the base.

[0023] The assembly method for automotive handlebar spring supports includes the following steps: Material loading: Workers load materials onto a material loading device. Start the turntable drive device. The turntable drive device drives the first and second turntables to rotate around their respective axes. The control device controls the turntable drive device so that the first positioning component on the first turntable moves to its corresponding station and then pauses rotation, waiting for the device at that station to activate. Simultaneously, the second positioning component on the second turntable moves to its corresponding station and then pauses rotation, waiting for the device at that station to activate. Start the material loading device: The control device controls the material loading device to load the first or second positioning components at each station. Start the first and second assembly devices: The control device controls the first or second assembly devices to assemble the components on the first or second positioning components at the corresponding stations together. After passing through all stations, the assembly of multiple automotive handlebar spring supports is completed.

[0024] By adopting the above technical solution, this method operates on assembly equipment with control and feeding devices. After initial manual feeding, the equipment can automatically drive the turntable to complete component positioning, workstation correspondence, and sequential pause, and cooperate with the assembly device to complete the assembly between components. Each step is coordinated by the control device to automatically complete the tasks of each process, ensuring large-scale, highly consistent automated assembly production.

[0025] Preferably, the control device stops the first turntable from rotating, the feeding device places a spring shell onto the first positioning assembly at the spring shell feeding station, and the turntable drive device drives the first turntable to rotate, moving the first positioning assembly to the annular spring feeding station; the control device stops the first turntable from rotating, the feeding device places an annular spring onto the first positioning assembly at the annular spring feeding station, and the turntable drive device drives the first turntable to rotate, moving the first positioning assembly to the positioning shaft feeding station; simultaneously, the control device stops the second turntable from rotating, the feeding device places a base onto the second positioning assembly at the base feeding station, and the turntable drive device drives the second turntable to rotate, moving the second positioning assembly to the elastic clamp feeding station; the control device stops the first turntable from rotating, the feeding device places a positioning shaft onto the first positioning assembly at the positioning shaft feeding station, the first assembly device pushes the annular spring into the spring shell, and the turntable drive device drives the first turntable to rotate. The first positioning component is moved to the transfer station; simultaneously, the control device stops the second turntable from rotating, and the feeding device places the elastic clamp onto the base of the second positioning component at the elastic clamp feeding station. The turntable drive device drives the second turntable to rotate, moving the second positioning component to the assembly station of the base and the elastic clamp. The second assembly device presses the elastic clamp into the base, and the turntable drive device drives the second turntable to rotate, moving the second positioning component to the placement station. The transfer device moves the spring housing and positioning shaft of the first positioning component at the transfer station to the second positioning component at the placement station. The turntable drive device drives the second turntable to rotate, moving the second positioning component to the assembly station of the base and the spring housing. The control device stops the second turntable from rotating, and the second assembly device pushes the spring housing into the mounting groove of the base, making the spring housing and the mounting hole coaxial. The second assembly device then pushes the positioning shaft into the base and the spring housing, completing the assembly.

[0026] By adopting the above technical solution, the feeding and assembly devices at different workstations are started sequentially, and the turntable is synchronously controlled, so that the components are assembled step by step by each sub-workstation. In particular, after the ring spring is assembled into the spring shell, it is smoothly transferred to the second turntable through the transfer device, realizing the fully automated process of mating with the base and finally inserting the positioning shaft. The steps are closely connected, the assembly rhythm is efficient, and finished products can be continuously output.

[0027] In summary, this application includes at least one of the following beneficial technical effects:

[0028] 1. By setting up a first turntable and a second turntable and their multiple corresponding first or second positioning components, the entire process of division of labor and positioning of components such as spring shell, ring spring, positioning shaft, base and elastic clamp is realized. Combined with the collaborative work of assembly device and transfer device, the entire process from material feeding to finished product output is automated, which greatly improves assembly efficiency and product consistency.

[0029] 2. The assembly equipment uses a partitioned layout of the first and second turntables to allow the pre-assembly of the spring housing, ring spring and positioning shaft and the final assembly of the base-related components to be carried out independently in different areas. Each turntable can operate synchronously, effectively avoiding process conflicts and waiting, improving the overall assembly cycle control capability, and is suitable for the needs of large-scale continuous production.

[0030] 3. The feeding device, assembly device, and unloading device in the invention are all linked to the control system. Through turntable and workstation cycle control, the assembly process is completed in a closed loop. This not only reduces manual intervention and improves operational safety, but also reduces assembly defects caused by human error, thereby enhancing the stability and production adaptability of the system.

When the eighth pneumatic finger 825 clamps, it will clamp the side of the spring shell 300 away from the base 200 and the side of the positioning strip 310 near the base 200. When the eighth pneumatic finger 825 clamps the spring shell 300 corresponding to the second positioning component 31, the second linear motor 823 drives the eighth pneumatic finger 825 to move, thereby moving the spring shell 300 closer to the base 200. When the spring shell 300 moves to be coaxial with the rotating shaft 834, the piston rod of the lateral telescopic cylinder 831 extends, causing the bent part 410 to be embedded in the embedding groove 8341. The rotary motor 833 drives the rotating shaft 834 to rotate 180 degrees, thereby causing the bent part 410 to face the base 200. The second linear motor 823 continues to drive the eighth pneumatic finger 825 to move, and the bent part 410 enters the base 200 through the third guide groove 345 and finally embeds into the base 200. At this time, the spring shell 300 is coaxially arranged with the mounting hole 240. The torsion mechanism 83 is used to drive the side of the rotary spring with the bent part 410 to rotate.

The third push rod 844 is coaxially aligned with the through hole 332 on the second positioning component 31 at the assembly station of the base 200 and the spring housing 300. When the second positioning component 31, which is pointed to by the third push rod 844, moves to the assembly station of the base 200 and the spring housing 300, the piston rod of the second horizontal drive cylinder 842 extends, and the third push rod 844 passes through the through hole 332 on the near side, pushing the positioning shaft 600 in the placement groove 331 through the through hole 332 on the other side, and into the base 200 and the spring housing 300 until it abuts against the abutment post 8292.

The second linear motor 823 drives the eighth pneumatic finger 825 to move towards the side closer to the base 200 until the spring shell 300 is coaxial with the rotating shaft 834. The rotary motor 833 drives the rotating shaft 834 to rotate, thereby rotating the annular spring 400, causing the annular spring 400 to be deformed by force, and the bent part 410 points towards the base 200. The second linear motor 823 then drives the eighth pneumatic finger 825 to move until the spring shell 300 and the mounting hole 240 on the base 200 are coaxial.
