Description

Technical Field

[0001] This invention relates to a positioning transfer platform for automotive structural components, belonging to the field of automotive manufacturing technology. Background Technology

[0002] In the automotive manufacturing industry, the accuracy of geometric tolerances for the holes and dimensions of automotive structural components is becoming increasingly important. If specialized measuring equipment is needed to inspect these dimensional tolerances, robots are typically used to move the workpieces. When the robot carries the workpiece into the measuring equipment using a fixture, the repeatability of the workpiece's positioning must be ensured. Besides achieving this through the repeatability of the fixture and the robot, a fine positioning of the workpiece is also required before the robot grips it to ensure initial accuracy. This is generally achieved using a positioning transfer table. Currently, commonly used transfer equipment in the industry mainly includes simple tooling pallets, fixed supports, and ordinary roller tables, which have the following technical shortcomings: 1. Insufficient positioning accuracy: Most existing transfer equipment lacks a dedicated positioning mechanism or only uses simple limit blocks for positioning. After the automotive structural parts are placed, they are prone to displacement and shaking, which requires recalibration when picking up the parts during the inspection process. This not only increases the operating time but also easily affects the inspection accuracy due to calibration errors.

[0003] 2. Poor adaptability: The size and shape of automotive structural parts vary greatly between different car models and types. Existing transfer equipment is mostly a fixed structure, which cannot flexibly adapt to the transfer needs of various specifications of workpieces. Special transfer equipment needs to be customized for different workpieces, which increases production input costs and occupies a large amount of production space.

[0004] 3. Insufficient stability: Instability of workpieces during transportation can easily lead to surface scratches and bumps, reducing the product qualification rate.

[0005] 4. Poor connectivity: Most existing transfer equipment only has the function of transfer or storage, and cannot achieve precise docking with the production equipment of the preceding and following processes. Manual assistance is required to pick up and put down workpieces, which not only increases the labor intensity of manual labor, but also reduces the automation level and production efficiency of the production line.

[0006] 5. Currently, most transfer stations are only used as positioning stations and cannot be used as fixture placement platforms. When used with robots, a separate robot fixture placement platform needs to be configured, which occupies equipment space and has high design and manufacturing costs. Summary of the Invention

Each suction cup is sequentially connected to the vacuum filter and vacuum generator above it via a pipeline.

[0011] Furthermore, each unloading fixture includes a mounting frame, a second robot hand-changing plate, a guide rod cylinder, a fixed arm, a pressure arm, and clamping blocks. The second robot hand-changing plate is located at the top of the mounting frame. The guide rod cylinder is horizontally mounted on one side of the mounting frame. The pressure arm is vertically fixed to the movable end of the guide rod cylinder. The lower part of the pressure arm is parallel to and opposite to the fixed arm. The fixed arm is located below the guide rod cylinder and fixed to the bottom of the mounting frame. There are two clamping blocks, which are fixed to the lower part of the fixed arm on the side opposite to the pressure arm. The clamping range of different unloading fixtures is different.

[0012] Furthermore, each clamping block, pressure arm, and fixing arm is coaxially provided with through holes.

[0013] Furthermore, each suction cup clamp and each unloading clamp is equipped with a detection switch.

[0014] Furthermore, the first pushing assembly includes a first driving mechanism mounted on the bracket and a first pushing plate detachably mounted on the movable end of the first driving mechanism, and the second pushing assembly includes a second driving mechanism and a second pushing plate detachably mounted on the movable end of the second driving mechanism, wherein the first driving mechanism and the second driving mechanism have the same structure.

[0017] Furthermore, the first pusher bracket is L-shaped, with one end facing downwards and installed at the movable end of the first drive mechanism, and the other end facing the tray direction.

The base plate is provided with a first clearance groove and a second clearance groove. The first clearance groove is located directly above the first drive mechanism, and the second clearance groove is located directly above the second drive mechanism.

[0021] The bracket serves as the mounting foundation and functional integration carrier for the automotive structural component positioning transfer platform, ensuring the rigidity and stability of the overall structure. It can effectively withstand the weight of the workpiece and its constituent structural components, as well as the impact force during operation, thus effectively ensuring the safety of production operations.

[0022] The automotive structural component positioning transfer table of the present invention is equipped with various types of clamps for sequential workpiece transfer operations. It can be adapted to the precise positioning and efficient operation of automotive structural components of different sizes, shapes and structures, solving the problem that most current positioning trays, positioning clamps and other equipment cannot be compatible with multiple workpieces, and meeting the multi-variety production needs of automated production lines.

Detailed Implementation

[0026] Specific implementation method one: Combining Figures 1-7 This description of embodiments provides a clear and complete description of the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] A positioning transfer table for automotive structural components includes a bracket 1, a positioning assembly, a mounting assembly, and a clamping assembly. The positioning assembly includes a tray 2, a first pushing assembly 3, and a second pushing assembly 4, all fixedly mounted on the bracket 1. The workpiece to be positioned is placed on the tray 2, which includes a base plate 21 and side baffles 22. The pushing directions of the first pushing assembly 3 and the second pushing assembly 4 are perpendicular to each other. The positioning of the workpiece is achieved jointly by the first pushing assembly 3, the second pushing assembly 4, and the side baffles 22. The mounting assembly includes a first mounting base 5 and a second mounting base 5 respectively fixed on the bracket 1. The clamping assembly includes a suction cup clamping set detachably mounted on the first mounting base 5 and a unloading clamping set mounted on the second mounting base 5. The suction cup clamping set includes a first to an Nth suction cup clamp, and the unloading clamping set includes a first to an Nth unloading clamp. The workpiece is rotated in sequence by a robot or a multi-axis gantry carrying the suction cup clamp or unloading clamp adapted to the workpiece.

[0028] The positioning component is used to achieve precise bidirectional positioning of automotive structural parts of various specifications in both the lateral and longitudinal directions, ensuring the initial accuracy when measuring the workpiece dimensions.

[0029] The pallet 2 is horizontally arranged to support the automotive structural parts to be positioned, providing a stable placement reference for the workpiece. The side baffles 22 of the pallet 2, together with the first pusher assembly 3 and the second pusher assembly 4, form an enclosing positioning structure. Through the coordinated cooperation of the first pusher assembly 3 and the second pusher assembly 4, the bidirectional positioning operation of the workpiece on the horizontal plane is completed.

[0030] The tray 2 is fixedly installed on the preset mounting surface of the bracket 1.

[0031] The first mounting base 5 provides an installation position for the suction cup clamp assembly, and the second mounting base 5 provides an installation position for the unloading clamp assembly.

[0032] The clamping assembly is used to stably clamp automotive structural parts of different shapes and specifications, adapting to the needs of transportation operations. Each clamp is detachably mounted on the first mounting base 5 and the second mounting base 5, allowing for quick switching, maintenance, and repair according to the workpiece type.

[0033] The suction cup clamp assembly preferably includes a first suction cup clamp 71 to a third suction cup clamp 73, and the unloading clamp assembly preferably includes a first unloading clamp 81 and a second unloading clamp 82. The first mounting base 5 has three corresponding suction cup clamp mounting positions, and the second mounting base 5 has two corresponding unloading clamp mounting positions. Each mounting position can be equipped with a locking mechanism, enabling manual installation, positioning, and disassembly of the clamps. It can also be quickly connected to a robot via a hand-changing plate to achieve automated operation.

[0034] The bracket 1 serves as the installation foundation and functional integration carrier for the automotive structural component positioning transfer platform. It is constructed using high-strength profiles joined at corners to ensure the rigidity and stability of the overall structure. It can effectively withstand the weight of the workpiece and each component, as well as the impact force during operation, thus effectively ensuring the safety of production operations.

[0035] The side baffle 22 is located on one side of the tray 2 and is arranged perpendicular to the tray 2. The side baffle 22 serves as a reference positioning plate and is preferably fixed vertically to one side edge of the tray 2.

[0036] The tray 2 and each clamp are preferably made of polyurethane or nylon to prevent scratches on the workpiece during positioning and transportation, and effectively improve the product qualification rate.

[0037] The automotive structural component positioning transfer table of the present invention is equipped with various types of clamps for sequential workpiece transfer operations. It can be adapted to the precise positioning and efficient operation of automotive structural components of different sizes, shapes and structures, solving the problem that most current positioning trays and positioning clamps cannot be compatible with multiple workpieces, and meeting the multi-variety production needs of automated production lines.

[0038] In this invention, a robot or multi-axis gantry carries a suction cup clamp or unloading clamp that is compatible with the workpiece to perform sequential workpiece rotation operations. By integrating the robot with quick-change clamps, it can achieve automated integration with dimensional measurement equipment, reduce manual intervention, improve the operating efficiency of the production line, and reduce manual transfer and positioning costs.

[0039] The components are rationally laid out, which facilitates daily maintenance and reduces equipment maintenance costs; manual or robotic hand-changing can be used, depending on the usage scenario.

[0040] During the transfer of automotive structural components, precise positioning is required to ensure the repeatability of the workpiece within the measuring equipment. Otherwise, deviations in form and position tolerance measurements will occur, leading to inaccurate results. Simultaneously, while meeting precise positioning requirements, the system must also be compatible with various workpieces to meet the demands of industrial environments. Adding a positioning transfer table to the process preceding the automotive structural components' entry into the measuring equipment not only achieves precise positioning to ensure measurement accuracy but also accommodates multiple workpieces, avoiding frequent changes and ensuring operational efficiency.

[0041] This turntable can be used for high-precision workpiece movement in other application scenarios that require precise workpiece positioning and sequential operation.

[0042] Each suction cup fixture includes a fixture profile 700, a first robot hand-changing plate 701 fixedly mounted on the upper end of the fixture profile 700 from top to bottom, a vacuum generator 702 and a vacuum filter 703, and a suction cup body 704 fixedly mounted on the lower end of the fixture profile 700. The suction cup in the suction cup body 704 is connected to the corresponding vacuum filter 703 and vacuum generator 702 above it via pipelines. With this design, the core structure of N suction cup fixtures is identical. Two first mounting pins can also be fixed on the first robot hand-changing plate 701 for engaging with mounting holes on the first mounting base 5 to achieve positioning and installation of the suction cup fixture. The fixture profile 700 can be mounted on the first mounting base 5. The suction cup body 704 is detachably mounted on the bottom end of the fixture profile 700, i.e., the end facing the workpiece, facilitating individual replacement and maintenance of the suction cup body 704. The vacuum generator 702 and vacuum filter 703 provide vacuum gripping conditions for the suction cup body 704. The first robot hand-changing plate 701 facilitates direct gripping of suction cup fixtures by the robot. The specific structural composition of the first robot hand-changing plate 701 is existing technology and will not be described in detail here. During use, N different specifications and layouts of vacuum suction cups can be installed according to the surface shape and clamping requirements of different workpieces. These combinations are suitable for various automotive structural parts with different structures, such as curved, flat, and irregularly shaped parts. Stable clamping of the workpiece is achieved through vacuum adsorption, avoiding damage caused by mechanical clamping, and adapting to the clamping requirements of thin-walled and easily deformable automotive structural parts.

[0043] The suction cup clamp assembly includes a first suction cup clamp 71, a second suction cup clamp 72, and a third suction cup clamp 73. The suction cup body 704 of the first suction cup clamp 71 includes a first suction cup frame 711 vertically fixed to the lower end of the clamp profile 700 and a first suction cup 712 installed at the lower end of the first suction cup frame 711. The suction cup body 704 of the second suction cup clamp 72 includes a second suction cup frame 721 horizontally fixed to the lower end of the clamp profile 700 and two second suction cups 712 respectively installed at both ends of the second suction cup frame 721. 22. The suction cup body 704 in the third suction cup fixture 73 includes a third suction cup frame 731 horizontally fixed to the lower end of the fixture profile 700 and two third suction cups 732 respectively installed at both ends of the third suction cup frame 731. The diameter of the third suction cup 732 is smaller than the diameter of the second suction cup 722, and the straight-line distance between the two third suction cups 732 is smaller than the straight-line distance between the two second suction cups 722. Each suction cup is connected to the vacuum filter 703 and vacuum generator 702 above it via a pipe. With this design, the core difference between the three suction cup fixtures lies in the different structural forms of the suction cup frame. The first suction cup fixture 71 uses a large suction cup, which is for workpieces with limited adsorption area and relatively heavy weight; the second suction cup fixture 72 uses two large suction cups, which is for workpieces with a large adsorption area, long length, and relatively heavy weight; and the third suction cup fixture 73 uses two small suction cups, which is for workpieces with small size and light weight.

[0044] Each unloading fixture includes a mounting frame 800, a second robot hand-changing plate 801, a guide rod cylinder 802, a fixed arm 803, a pressure arm 804, and clamping blocks 805. The second robot hand-changing plate 801 is located at the top of the mounting frame 800. The guide rod cylinder 802 is horizontally mounted on one side of the mounting frame 800. The pressure arm 804 is vertically fixed to the movable end of the guide rod cylinder 802. The lower part of the pressure arm 804 is parallel to and opposite to the fixed arm 803. The fixed arm 803 is located below the guide rod cylinder 802 and fixed to the bottom of the mounting frame 800. There are two clamping blocks 805, which are fixed to the lower part of the fixed arm 803 on the side opposite to the pressure arm 804. The clamping range of different unloading fixtures is different. This design allows for rapid docking and replacement with the robot via the second robot changing plate 801. The guide rod cylinder 802 drives the extension and retraction of the pressure arm 804, causing the two opposing clamping blocks 805 to move closer to or away from the workpiece, achieving automatic clamping and release. Each unloading fixture can achieve robot quick change and automatic clamping / releasing functions. The difference lies in the length of the clamping blocks 805 and the corresponding lengths of the fixed arm 803 and pressure arm 804 in different unloading fixtures. This allows for adaptation to automotive structural parts of different lengths or with special structures, compensating for the clamping range limitations of single-size unloading fixtures and expanding the device's adaptability. The clamping blocks 805 are preferably made of polyurethane, which has good elasticity and wear resistance, ensuring effective clamping of the workpiece while preventing scratches or pressure damage to the workpiece surface during clamping, protecting the workpiece's appearance and structural integrity. For longer fixed arms 803 and / or pressure arms 804, reinforcing ribs 807 can be provided on the side opposite to the clamping blocks 805. The bottom of the mounting bracket 800 is fixed with a second mounting pin 806, which is used to cooperate with the mounting hole on the second mounting base 5 to realize the positioning and installation of the unloading fixture.

[0045] Each clamping block 805, pressure arm 804, and fixing arm 803 has a through hole coaxially formed. This design allows a proximity switch to be installed at the through hole to detect whether the fixture is clamping the workpiece.

[0046] Each suction cup gripper and each unloading gripper is equipped with a detection switch 9. This design allows for real-time detection of whether the gripper is properly installed. The detection switch 9 can be a proximity switch, with each gripper corresponding to its mounting base. A detection mechanism is integrated on the bracket 1 or the mounting base of the gripper. The detection signal can be transmitted to the production line control system, enabling real-time monitoring of the gripper installation status. This avoids operational malfunctions caused by missing or improperly installed grippers, improving operational safety and reliability. Furthermore, the detection positions of each gripper can be set differently, effectively preventing collisions during automated operation caused by incorrect gripper placement and robot hand-switching.

[0047] The first pushing assembly 3 includes a first driving mechanism 31 mounted on the bracket 1 and a first pushing plate 32 detachably mounted on the movable end of the first driving mechanism 31. The second pushing assembly 4 includes a second driving mechanism 41 and a second pushing plate 42 detachably mounted on the movable end of the second driving mechanism 41, wherein the first driving mechanism 31 and the second driving mechanism 41 have the same structure. With this design, the first pushing plate 32 and the second pushing plate 42 are detachably mounted on their respective driving mechanism movable ends, and the appropriate size pushing plate can be replaced according to the structure and size of the workpiece. During operation, the first driving mechanism 31 controls the first pushing plate 32 to perform reciprocating linear motion, thereby pushing the workpiece on the tray 2 towards the lateral limiting surface opposite to the first pushing plate 32 until it is in close contact with the side baffle 22, achieving precise positioning of the workpiece in the X direction; the second driving mechanism 41 controls the second pushing plate 42 to perform reciprocating linear motion, thereby pushing the workpiece on the tray 2 to move, achieving precise positioning of the workpiece in the Y direction.

[0048] The first driving mechanism 31 includes a first servo motor 311 and a first linear module 312. The first servo motor 311 is mounted on the bracket 1, the first linear module 312 is mounted on the output end of the first servo motor 311, and the first pusher plate 32 is mounted on the sliding end of the first linear module 312. In this design, the sliding end of the first linear module 312 is the moving end of the first driving mechanism 31. Using a servo motor to drive the linear module achieves precise positioning during pushing, with a pushing accuracy controlled within ±0.05mm. Combined with the limiting effect of the fixed side baffle 22, the consistency of workpiece positioning can be guaranteed.

[0049] The first pusher plate 32 is connected to the first drive mechanism 31 via a first pusher bracket 33, and the connection between the first pusher plate 32 and the first pusher bracket 33 is detachable. Similarly, the second pusher plate 42 is connected to the second drive mechanism 41 via a second pusher bracket 43, and the connection between the second pusher plate 42 and the second pusher bracket 43 is detachable. This design, by providing the first pusher bracket 33 and the second pusher bracket 43, facilitates the connection between the first pusher plate 32 and the second pusher plate 42 and their corresponding drive mechanisms, ensures the installation height of the first pusher plate 32 and the second pusher plate 42, avoids interference with the tray 2, and further improves the positioning effect.

[0050] The first pusher bracket 33 is L-shaped, with one end facing downwards and mounted on the movable end of the first drive mechanism 31, and the other end facing the tray 2. The first pusher plate 32 is mounted on the other end of the first pusher bracket 33. The base plate 21 is fixed to the bracket 1 by several support rods 23 and is located above the first drive mechanism 31 and the second drive mechanism 41. The base plate 21 has a first clearance groove 211 and a second clearance groove 212. The first clearance groove 211 is located directly above the first drive mechanism 31, and the second clearance groove 212 is located directly above the second drive mechanism 41. This design, by making the first pusher bracket 33 L-shaped, can increase the moving stroke of the first pusher plate 32 while ensuring the installation height of the first pusher plate 32, thereby further ensuring the positioning effect.

[0051] The side baffle 22 forms a lateral limiting surface. The first clearance groove 211 facilitates the passage of the first pusher bracket 33, and the second clearance groove 212 facilitates the passage of the second pusher bracket 43, thereby further increasing the travel distance of the first pusher plate 32 and the second pusher plate 42 in the X and Y directions. At the same time, the first clearance groove 211 and the second clearance groove 212 also play a role in weight reduction.

[0052] Working principle: Taking a suction cup clamping set consisting of three suction cup clamps and a material unloading clamping set consisting of two material unloading clamps as an example: The material receiving method of the positioning transfer station is based on customer needs. A robot or a multi-axis gantry carries one of the three sets of suction cup clamps. The movement trajectory of the suction cup clamp covers the loading frame and the positioning transfer station. After the workpiece in the loading frame is sucked up, it is moved to the top of the positioning transfer station. At a specific position of the workpiece, the suction cup clamp puts the workpiece down. The workpiece is precisely positioned by the coordinated operation of the side baffle 22, the first pushing component 3 and the second pushing component 4. After positioning, workpiece measurement and other operations are performed. The unloading method of the positioning transfer station is based on customer needs. It uses a robot or a multi-axis gantry to carry one of the two sets of unloading fixtures. The movement trajectory of the robot carrying the unloading fixture covers the unloading position and the positioning transfer station. After the unloading fixture grabs the workpiece, it transfers the workpiece to the next station for inspection.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
