Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing, and in particular to a multi-station feeding device and processing equipment for the front floor of an automobile. Background Technology

[0002] In automobile manufacturing, the front floor, as a crucial component of the vehicle body structure, directly impacts the overall vehicle safety performance due to its welding quality. Existing feeding methods typically employ single-station fixtures, resulting in long loading times and low equipment utilization. Utility Model Content

[0003] Therefore, there is a need to provide a multi-station feeding device and processing equipment for the front floor of automobiles, in order to solve the technical problems of existing feeding methods that usually use a single-station fixture, resulting in long feeding time and low equipment utilization.

[0004] To achieve the above objectives, in a first aspect, this utility model provides a multi-station feeding device for the front floor of an automobile, comprising:

[0005] The rotating mechanism includes a mounting base, a rotating drive unit, and a rotating bracket. The rotating drive unit is mounted on the mounting base, and the output end of the rotating drive unit is connected to the rotating bracket. The rotating bracket is located above the rotating drive unit and has two or more rotating positions.

[0006] Two or more clamping mechanisms, each clamping mechanism is installed on a rotary station, the clamping mechanism includes a clamping base and two or more clamping components, two or more clamping components are installed on the clamping base, and the two or more clamping components cooperate to clamp and fix the front floor of the car.

[0007] Unlike existing technologies, the technical solution of this application achieves continuous feeding of the automotive front floor by using a rotating mechanism to drive multiple clamping mechanisms to work alternately, shortening the feeding time and effectively improving production efficiency. The rotating drive unit can use a servo motor or a hydraulic motor, which can precisely control the rotation angle and ensure accurate positioning of each station. The coordinated work of multiple clamping components can stably clamp the automotive front floor, preventing displacement during rotation and welding, and ensuring processing accuracy.

[0008] As one embodiment of this utility model, the rotating mechanism also includes two baffles, which are symmetrically installed on both sides of the rotating bracket, and the two baffles are used to isolate the working area.

[0009] In this way, the two symmetrically positioned baffles effectively isolate the work area, preventing external personnel or objects from accidentally entering and significantly improving the safety of equipment operation. At the same time, the baffles also block spatter generated during welding, protecting surrounding equipment from damage.

[0010] As one embodiment of the present invention, the clamping mechanism further includes a controller, which is mounted on the clamping base and is communicatively connected to the clamping assembly. The controller is used to control the clamping state of the clamping assembly.

[0011] Thus, the controller is designed to allow operators to easily control the clamping and releasing states of the fixture components, improving the ease of operation.

[0012] As one embodiment of this utility model, the rotating bracket has a first rotating station and a second rotating station symmetrically arranged with respect to the first rotating station. The clamping mechanism is provided with a first clamping mechanism and a second clamping mechanism. The first clamping mechanism is installed on the first rotating station, and the second clamping mechanism is installed on the second rotating station. The layout of the first clamping mechanism is the layout of the second clamping mechanism after rotating counterclockwise by 180°.

[0013] Thus, the first and second clamping mechanisms adopt a 180° symmetrical layout design, which allows the front floor of the car on both workstations to enter the welding position in the same posture, simplifying the subsequent welding difficulty, improving the consistency of the welding path, and helping to ensure the stability of welding quality.

[0014] As one embodiment of this utility model, the clamping mechanism further includes two or more casters, which are installed at the bottom of the clamping base and located on the outside of the rotating bracket.

[0015] Thus, equipping the fixture base with casters facilitates quick movement of the fixture during disassembly, maintenance, or mold line changes, enabling convenient transfer and positioning of the fixture.

[0016] As one embodiment of this utility model, the clamping mechanism also includes a telescopic rod, which is installed at the outer end of the clamping base.

[0017] Thus, the telescopic lever combined with casters further enhances the mobility of the clamping mechanism, allowing operators to easily push it forward. Furthermore, the telescopic design enables the lever to be retracted in different working states, saving space.

[0018] As one embodiment of this utility model, the rotating mechanism also includes two or more position sensors, which are installed in the middle of the rotating bracket. Each position sensor corresponds to a clamping mechanism, and the position sensor is used to detect that the clamping mechanism is in place.

[0019] In this way, the position sensor enables real-time monitoring of the clamping mechanism's placement status. The rotating mechanism will only start working once the position sensor detects that the clamping mechanism is in place, effectively preventing equipment failures caused by the clamp not being placed in place and improving operational reliability.

[0020] As one embodiment of this utility model, the clamping mechanism further includes a mounting base plate, which is installed at the bottom of the clamping base. The mounting base plate has two or more mounting holes, and the clamping base has through holes at corresponding positions of the two or more mounting holes. The two or more mounting holes are mounted on the rotating bracket by fasteners.

[0021] In this way, a reliable and repeatable mechanical connection is achieved between the clamping mechanism and the rotating support through the mating of the mounting holes and through holes. The through holes prevent the fasteners from interfering with the clamp base, facilitating quick assembly and disassembly and accurate alignment of the clamping mechanism.

[0022] To achieve the above objectives, in a second aspect, this utility model also provides a processing device for the front floor of an automobile, comprising:

[0023] As provided by the inventor above, a multi-station feeding device for the front floor of an automobile.

[0024] Two or more welding robotic arms are located on either side of one of the rotary stations, and the welding robotic arms are used to weld the front floor of a car on the rotary station.

[0025] Unlike existing technologies, the technical solution of this application enables automated welding production of the front floor of automobiles through the coordinated operation of a multi-station feeding device and a welding robotic arm. While one rotating station is performing welding operations, another rotating station can perform material feeding operations, which greatly shortens the production cycle and improves equipment utilization.

[0026] As one embodiment of this utility model, the processing equipment for the front floor of an automobile also includes a material handling robot arm, which is located on one side of one of the rotating stations and is used to clamp the welded front floor of the automobile to the testing equipment.

[0027] In this way, by configuring a robotic arm for material handling and linking it with the inspection equipment, the welded front floor of the car can be promptly removed and entered into the inspection equipment for online testing, shortening the production line cycle time and improving the speed of quality feedback. At the same time, the automated docking of the robotic arm can reduce manual handling, improve production continuity, and facilitate online quality traceability and defect correction.

[0028] The above description of the utility model is merely an overview of the technical solution of this application. In order to enable those skilled in the art to better understand the technical solution of this application and to implement it based on the description and drawings, and to make the above-mentioned objectives and other objectives, features and advantages of this application easier to understand, the following description is provided in conjunction with the specific embodiments and drawings of this application.

[0048] In automobile manufacturing, the front floor, as a crucial component of the vehicle body structure, directly impacts the overall vehicle safety performance due to its welding quality. Existing feeding methods typically employ single-station fixtures, resulting in long loading times and low equipment utilization.

[0049] In view of this, this application provides a multi-station feeding device 100 for a car front floor 200, including a rotating mechanism 1 and two or more clamping mechanisms 2. The rotating mechanism 1 includes a mounting base 11, a rotating drive unit 12, and a rotating bracket 13. The rotating drive unit 12 is mounted on the mounting base 11, and the output end of the rotating drive unit 12 is connected to the rotating bracket 13. The rotating bracket 13 is located above the rotating drive unit 12 and has two or more rotating stations 131. Each clamping mechanism 2 is mounted on a rotating station 131. The clamping mechanism 2 includes a clamping base 21 and two or more clamping assemblies 22. Two or more clamping assemblies 22 are mounted on the clamping base 21, and the two or more clamping assemblies 22 cooperate to clamp and fix the car front floor 200.

[0050] According to some embodiments of this application, this embodiment relates to a processing equipment for a front floor 200 of an automobile, including a multi-station feeding device 100 for the front floor 200 of the automobile and two or more welding robotic arms, the two or more welding robotic arms being located on both sides of one of the rotating stations 131, the welding robotic arms being used to weld the front floor 200 of the automobile on the rotating station 131.

[0051] One of the rotating stations 131 is designated as the welding position, and two or more welding robotic arms are installed at this welding position. Therefore, when the rotating station 131 rotates to the welding position, the welding process begins. In this embodiment, a welding robotic arm is installed on each side of one of the rotating stations 131, and the welding robotic arms can simultaneously weld the front floor 200 of the vehicle, improving welding efficiency.

[0052] The welding robotic arm can be a spot welding arm, an arc welding arm, or a laser welding arm, with its end effector selected according to the process (such as a spot welding clamp, welding torch, etc.). The control system schedules the movements of the rotating mechanism 1 and the welding robotic arm to achieve multi-point collaborative welding within the welding position.

[0053] The technical solution of this application enables the automated welding production of the front floor of an automobile 200 through the coordinated operation of the multi-station feeding device 100 and the welding robot arm. While one rotary station 131 is performing welding operations, another rotary station 131 can perform material feeding operations, which greatly shortens the production cycle and improves equipment utilization.

[0054] According to some embodiments of this application, optionally, the processing equipment for the front floor of an automobile 200 further includes a material handling robot arm located on one side of one of the rotating stations 131, which is used to clamp the welded front floor of the automobile 200 to the testing equipment.

[0055] The inspection equipment may be a dimensional inspection table, an appearance camera, or a functional testing device. In some embodiments, the picking robot arm may be equipped with a vision guidance system or a force / position composite end effector, and the inspection equipment may be linked with a production information system to record inspection results and realize rework or rejection processes.

[0056] In actual operation, the operator first installs the front floor 200 of the automobile on a rotary station 131 and places the corresponding parts on it. After placement, the rotating mechanism 1 rotates the rotary station 131 to the welding position, and the welding robotic arms on both sides simultaneously perform welding operations, welding the parts onto the front floor 200. Meanwhile, the other rotary station 131 can prepare for clamping the next front floor 200, achieving continuous production. After welding is completed, the unloading robotic arm transfers the front floor 200 to the inspection equipment for testing.

[0057] In this way, by configuring a robotic arm for material handling and linking it with the testing equipment, the welded front floor 200 of the car can be promptly removed and entered into the testing equipment for online inspection, shortening the production line cycle time and improving the speed of quality feedback. At the same time, the automated docking of the robotic arm can reduce manual handling, improve production continuity, and facilitate online quality traceability and defect correction.

[0058] According to some embodiments of this application, please refer to Figures 1 to 6 This embodiment also relates to a multi-station feeding device 100 for a car front floor 200, including a rotating mechanism 1 and two or more clamping mechanisms 2. The rotating mechanism 1 includes a mounting base 11, a rotating drive unit 12, and a rotating bracket 13. The rotating drive unit 12 is mounted on the mounting base 11, and the output end of the rotating drive unit 12 is connected to the rotating bracket 13. The rotating bracket 13 is located above the rotating drive unit 12 and has two or more rotating stations 131. Each clamping mechanism 2 is mounted on a rotating station 131. The clamping mechanism 2 includes a clamping base 21 and two or more clamping assemblies 22. Two or more clamping assemblies 22 are mounted on the clamping base 21, and the two or more clamping assemblies 22 cooperate to clamp and fix the car front floor 200.

[0059] The mounting base 11 is installed on the ground. Specifically, a groove is provided in the ground for the mounting base 11 to be installed, and the mounting base 11 is recessed. The rotary drive unit 12 is an existing structure and can use a servo motor with a reducer. The output end is connected to the rotary support 13 through a coupling. The rotary support 13 can be a straight or cross-shaped structure, and can be provided with two or four rotary stations 131. The angle between two adjacent rotary stations 131 is the same. For example, if the rotary support 13 is provided with two rotary stations 131, the angle between the two rotary stations 131 is 180°.

[0060] The clamping assembly 22 can be an existing clamp, such as a locating pin, a cylinder-driven clamping claw, or a spring clamping element, and can be modularly designed to adapt to the front floor of different vehicle models.

[0061] The technical solution of this application achieves continuous feeding of the automotive front floor 200 by using a rotating mechanism 1 to drive multiple clamping mechanisms 2 to work alternately, thus shortening the feeding time and effectively improving production efficiency. The rotating drive unit 12 can be a servo motor or a hydraulic motor, capable of precisely controlling the rotation angle to ensure accurate positioning at each station. The coordinated work of multiple clamping components 22 can stably clamp the automotive front floor 200, preventing displacement during rotation and welding, and ensuring processing accuracy.

[0062] like Figure 1 , Figure 2 and Figure 4As shown, the rotating mechanism 1 also includes two baffles 14, which are symmetrically installed on both sides of the rotating bracket 13. The two baffles 14 are used to isolate the working area.

[0063] The baffle 14 can be made of metal plate or transparent heat-resistant material, and the baffle 14 can be directly connected to the rotating bracket 13 by bolts.

[0064] Thus, the two symmetrically arranged baffles 14 effectively isolate the work area, preventing external personnel or objects from accidentally entering and significantly improving the safety of equipment operation. At the same time, the baffles 14 can also block spatter generated during welding, protecting surrounding equipment from damage.

[0065] like Figure 5 As shown, the clamping mechanism 2 also includes a controller 23, which is mounted on the clamping base 21 and is communicatively connected to the clamping assembly 22. The controller 23 is used to control the clamping state of the clamping assembly 22.

[0066] Thus, the controller 23 allows the operator to easily control the clamping and releasing states of the clamping assembly 22, improving the ease of operation.

[0067] like Figure 3 and Figure 4 As shown, the rotating bracket 13 has a first rotating station 132 and a second rotating station 133 symmetrically arranged with respect to the first rotating station 132. The clamping mechanism 2 is provided with a first clamping mechanism 24 and a second clamping mechanism 25. The first clamping mechanism 24 is installed on the first rotating station 132, and the second clamping mechanism 25 is installed on the second rotating station 133. The layout of the first clamping mechanism 24 is the layout of the second clamping mechanism 25 after rotating counterclockwise by 180°.

[0068] In this embodiment, the rotating bracket 13 is in the shape of a straight line and has two symmetrically arranged rotating stations 131, namely the first rotating station 132 and the second rotating station 133. The position and structure of the clamp on the first clamping mechanism 24 are obtained by rotating it 180° counterclockwise to the position and structure of the clamp on the second clamping mechanism 25.

[0069] Two baffles 14 are located between the first rotary station 132 and the second rotary station 133, separating the first rotary station 132 from the second rotary station 133 to separate the material loading area from the welding area. Figure 4 As shown, in this embodiment, the first rotary station 132 can be set as the material feeding area, and the second rotary station 133 can be set as the welding area.

[0070] Thus, the first clamping mechanism 24 and the second clamping mechanism 25 adopt a 180° symmetrical layout design, which enables the front floor of the car on both workstations to enter the welding position in the same posture, simplifying the subsequent welding difficulty, improving the consistency of the welding path, and helping to ensure the stability of welding quality.

[0071] like Figure 6 As shown, the clamping mechanism 2 also includes two or more casters 26, which are mounted on the bottom of the clamping base 21 and located on the outside of the rotating bracket 13.

[0072] In this embodiment, a caster 26 is installed at each of the four corners of the bottom of the clamp base 21.

[0073] Thus, the fixture base 21 is equipped with casters 26, which facilitates quick movement of the fixture during disassembly, maintenance or mold line change, and enables convenient transfer and positioning of the fixture.

[0074] According to some embodiments of this application, optionally, the clamping mechanism 2 further includes a telescopic rod, which is installed at the outer end of the clamping base 21.

[0075] The telescopic lever, serving as a loading / unloading handle or positioning guide, can employ a telescopic structure and include a locking device. It is used for mechanical docking between the clamp and the rotating bracket 13 or for pulling the clamp out / pushing it into the installation position. The telescopic lever works in conjunction with the casters 26 to enhance the ease of loading and unloading.

[0076] Thus, the telescopic lever, in conjunction with the casters 26, further enhances the mobility of the clamping mechanism 2, allowing operators to easily push it. Furthermore, the telescopic design enables the lever to be retracted in different working states, saving space.

[0077] According to some embodiments of this application, optionally, the rotating mechanism 1 further includes two or more position sensors, which are installed in the middle of the rotating bracket 13. Each position sensor corresponds to a clamping mechanism 2, and the position sensor is used to detect that the clamping mechanism 2 is placed in place.

[0078] The position sensor can be a proximity switch, photoelectric sensor or magnetic sensor, and the signal is connected to the PLC to control rotation stop, fixture locking and the start of subsequent processes.

[0079] In this way, the position sensor enables real-time monitoring of the placement status of the clamping mechanism 2. The rotating mechanism 1 will only start working when the position sensor detects that the clamping mechanism 2 is in place, which effectively prevents equipment failure caused by the clamp not being placed in place and improves operational reliability.

[0080] like Figure 5 and Figure 6As shown, the clamping mechanism 2 also includes a mounting base plate 27, which is installed on the bottom of the clamping base 21. The mounting base plate 27 has two or more mounting holes 271. The clamping base 21 has through holes 211 at the corresponding positions of the two or more mounting holes 271. The two or more mounting holes 271 are installed on the rotating bracket 13 by fasteners.

[0081] Multiple mounting base plates 27 can be provided. In this embodiment, four mounting base plates 27 are provided and installed in the four directions of front, back, left, and right at the bottom of the clamp base 21, so that the mounting holes 271 are distributed, which can more firmly install the clamp base 21 onto the rotating bracket 13. The through holes 211 provide operating space for the installation of fasteners (such as bolts, screws, or studs, etc.), making it easier for operators to firmly install the clamp mechanism 2 onto the rotating bracket 13.

[0082] Thus, through the cooperation of mounting hole 271 and through hole 211, a reliable and repeatable mechanical connection is achieved between clamping mechanism 2 and rotating bracket 13. The through hole 211 prevents the fastener from interfering with clamp base 21, facilitating quick assembly and disassembly and accurate alignment of clamping mechanism 2.

[0083] It should be noted that although the above embodiments have been described herein, this does not limit the scope of patent protection for this utility model. Therefore, any changes and modifications made to the embodiments described herein based on the innovative concept of this utility model, or equivalent structural or procedural transformations made using the content of this utility model's specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields, are all included within the scope of patent protection for this utility model.
