Description

Technical Field

[0001] This utility model relates to the technical field of workpiece assembly auxiliary equipment, specifically to a reversing material transfer component for tooling assembly. Background Technology

[0002] In the field of precision workpiece assembly (such as electronic components, automotive parts, and hardware accessories), reversing and material transfer is a core process connecting various assembly stations. Its operational efficiency, positioning accuracy, and mechanism stability directly determine the overall production line capacity and product qualification rate. Currently, existing workpiece reversing and material transfer equipment is mainly divided into two categories: one type uses multiple independent drive mechanisms in conjunction with a steering module to achieve reversing. That is, after the workpiece is transported to the designated position by a linear material transfer component, a special rotary fixture or steering platform adjusts the workpiece's posture, and then another set of material transfer components transports it to the next station; the other type uses an integrated turntable structure with multiple receiving positions on the turntable. The rotation of the turntable drives the workpiece to change direction, while a single material transfer device completes loading and unloading.

[0003] However, the aforementioned existing technologies have significant shortcomings: For multi-mechanism cooperative equipment, the structure is complex and the number of parts is large, which not only occupies a lot of space and has high manufacturing costs, but also makes it difficult to coordinate and debug the multi-mechanism, which is prone to problems such as action delay and poor connection, resulting in low material transfer efficiency. At the same time, the alignment errors of the steering module and the material transfer component are easy to accumulate, affecting the workpiece reversing accuracy and making it difficult to adapt to the high-precision batch assembly requirements. For integrated turntable equipment, the layout of the receiving positions on the turntable is mostly a single arrangement or asymmetrical design, which cannot realize the continuous flow operation of workpiece loading, reversing and unloading. Moreover, the material transfer device is mostly a single-dimensional or two-dimensional moving structure, which has poor flexibility and is difficult to adapt to the distance and height requirements of different workstations. At the same time, the large gap between the drive components and moving parts of some equipment makes it easy to jam and deviate, resulting in insufficient workpiece posture stability, which in turn affects the subsequent assembly quality.

[0004] Therefore, in view of the problems of existing reversing and material transfer equipment such as complex structure, insufficient precision, low efficiency and poor stability, there is an urgent need for a reversing and material transfer component for workpiece assembly that is compact in structure, has smooth operation, accurate positioning and is suitable for batch operation, so as to make up for the defects of existing technology and meet the high-efficiency operation requirements of precision workpiece assembly production line. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art.

[0006] This application provides a reversing and material transfer assembly for workpiece assembly, including a turntable, a rotary driver, a pair of loading platforms, a pair of transfer devices, and several receiving platforms. The rotary driver is connected to the turntable to drive the turntable to rotate around its own axis. Each receiving platform is correspondingly arranged on the table surface of the turntable and the table surface of each loading platform. The pair of transfer devices cooperate to transfer the workpiece from the receiving platform of the current station to the receiving platform of the subsequent station.

[0007] The receiving platforms on each loading platform are arranged in a straight line. There are two sets of receiving platforms on the turntable. Each set of receiving platforms includes two receiving platforms, and the two sets of receiving platforms are symmetrically distributed with the central axis of the turntable as the axis of symmetry.

[0008] The rotary drive is an electric motor.

[0009] The material transfer device includes a mounting plate, several grippers, a lifting frame, a longitudinal frame, a transverse plate, a mounting platform, and several linear drive components. Each linear drive component is used to raise and lower the lifting frame relative to the longitudinal frame, move the longitudinal frame longitudinally relative to the transverse plate, and move the transverse plate transversely relative to the mounting platform. The mounting plate is fixed on the lifting frame, and each gripper is arranged on the mounting plate at intervals along a straight line.

[0010] The linear drive assembly includes several slide rail pairs and several linear actuators. Each slide rail pair is respectively arranged between the lifting frame and the longitudinal frame, between the longitudinal frame and the transverse plate, and between the transverse plate and the mounting platform. Each linear actuator is used to drive the lifting frame, the longitudinal frame, and the transverse plate to move along the corresponding slide rail pair.

[0011] Several reinforcing plates connect the mounting plate and the lifting frame.

[0012] It also includes a support truss, the top of which is slidably engaged with the end of the transverse plate away from the mounting platform via a slide rail pair.

[0013] The linear actuator is a cylinder, and the cylinder body is mounted on a longitudinal frame, transverse plate, or mounting platform. The outer end of the cylinder piston rod is connected to the lifting frame, longitudinal frame, or transverse plate.

[0014] The longitudinal frame includes a base plate, a pair of side plates, and a pair of crossbeams. The base plate is connected to the bottom of the pair of side plates, and the pair of crossbeams are connected to the top of the pair of side plates. A through hole is also opened on the base plate. A cylinder for driving the lifting frame to rise and fall is installed at the bottom of the base plate, and the piston rod passes through the through hole to connect to the lifting frame.

[0015] It also includes a pair of guide plates and a pair of guide rods. The pair of guide plates are symmetrically fixed on the inner side wall of the lifting frame, and each guide plate has a guide hole longitudinally opened. The pair of guide rods are symmetrically fixed on the base plate and slide through the corresponding guide hole.

[0016] The beneficial effects of this utility model are as follows:

[0017] 1. Through the cooperation of a turntable (with two sets of symmetrical receiving platforms) and a rotary drive, the rotary drive drives the turntable to rotate around its own axis. The receiving platforms of the loading platform are arranged in a straight line. The transfer device transfers the workpiece between the loading platform and the turntable receiving platform. The workpiece reversal adjustment can be completed without an additional reversing mechanism, simplifying the overall structure while ensuring the positioning accuracy of the workpiece during the reversal process, avoiding the impact of offset on the subsequent assembly quality, realizing the continuous operation of loading, reversing, and unloading, and greatly improving the degree of automation and transfer efficiency.

[0018] 2. The linear drive component of the material transfer device works in conjunction with the slide rail pair. The linear drive component drives the lifting frame, longitudinal frame, and transverse plate to move along the corresponding slide rail pair, thereby enabling the gripper to move precisely in three-dimensional space. The grooves on the mounting plate limit the gripper's position, and the reinforcing plate enhances the connection rigidity, effectively preventing gripper wobbling, interference, and deformation under stress. This ensures the stability of the posture during simultaneous transfer of multiple workpieces, making it suitable for batch operations in high-precision assembly scenarios.

[0019] 3. Using a cylinder as a linear actuator, the cylinder body and piston rod are connected to corresponding components. Combined with the frame structure of the longitudinal transfer frame (base plate, side plate, crossbeam) and the guiding cooperation of the guide plate and guide rod, the cylinder quickly drives the movement of each component, improving the material transfer cycle. The frame structure balances strength and lightness to reduce the drive load. The guide components prevent the lifting frame from tilting and jamming. At the same time, the cylinder is installed in a hidden manner to optimize the layout, avoid component interference, and improve the space utilization and movement stability of the components.

Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0030] The reversing and material transfer assembly for workpiece assembly provided in this application will be described in detail below with reference to the accompanying drawings and through specific embodiments and application scenarios.

[0031] Example 1:

[0032] This application provides a reversing and material transfer assembly for workpiece assembly, including a turntable 1, a rotary driver 2, a pair of loading platforms 3, a pair of transfer devices 4, and several receiving platforms 5. The rotary driver 2 is driven to connect to the turntable 1 to drive the turntable 1 to rotate around its own axis. Each receiving platform 5 is correspondingly arranged on the platform of the turntable 1 and the platform of each loading platform 3. The pair of transfer devices 4 cooperate to transfer the workpiece from the receiving platform 5 of the current station to the receiving platform 5 of the subsequent station.

[0033] In this embodiment of the application, the receiving platforms 5 on each material carrier 3 are arranged sequentially along the same straight line. Two sets of receiving platforms 5 are provided on the table surface of the turntable 1. Each set of receiving platforms 5 includes two receiving platforms 5, and the two sets of receiving platforms 5 are symmetrically distributed with the central axis of the turntable 1 as the axis of symmetry.

[0034] In this embodiment of the application, the rotary driver 2 is a motor.

[0035] like Figures 1 to 6 As shown, due to the above structure, workpieces can be orderly fed through the linear receiving platform 5 of one set of loading platforms 3. After the transfer device 4 transfers the workpiece to the receiving platform 5 of the turntable 1, the motor drives the turntable 1 to rotate at a preset angle. The two sets of symmetrically distributed receiving platforms 5 are used to realize the reversal adjustment of the workpieces, without the need for additional reversal mechanisms, which simplifies the overall structure. After the reversal is completed, the other set of transfer devices 4 can quickly transfer the workpiece to the receiving platform 5 of another set of loading platforms 3 for subsequent assembly processes, realizing the continuous operation of loading, reversal, and unloading, which greatly improves the automation level of workpiece assembly and the efficiency of material transfer. At the same time, the symmetrically distributed receiving platforms 5 can ensure the positioning accuracy of the workpieces during the reversal process and avoid the workpiece offset from affecting the subsequent assembly quality.

[0036] Example 2:

[0037] In this embodiment, in addition to the structural features of the aforementioned embodiments, the material transfer device 4 includes a mounting plate 41, a plurality of grippers 42, a lifting frame 43, a longitudinal frame 44, a transverse plate 45, a mounting platform 46, and a plurality of linear drive components 47. Each linear drive component 47 is used to lift the lifting frame 43 relative to the longitudinal frame 44, move the longitudinal frame 44 relative to the transverse plate 45, and move the transverse plate 45 relative to the mounting platform 46. The mounting plate 41 is fixed on the lifting frame 43, and each gripper 42 is arranged at intervals along a straight line on the mounting plate 41.

[0038] In this embodiment of the application, the linear drive assembly 47 includes a plurality of slide rail pairs 471 and a plurality of linear drivers 472. Each slide rail pair 471 is respectively disposed between the lifting frame 43 and the longitudinal frame 44, between the longitudinal frame 44 and the transverse plate 45, and between the transverse plate 45 and the mounting platform 46. Each linear driver 472 drives the lifting frame 43, the longitudinal frame 44 and the transverse plate 45 to move respectively.

[0039] In this embodiment of the application, a plurality of reinforcing plates 48 are connected between the mounting plate 41 and the lifting frame 43.

[0040] In this embodiment of the application, the mounting plate 41 is provided with a plurality of grooves 49 for accommodating the grippers 42.

[0041] In this embodiment of the application, a support truss 410 is also included, the top of which is slidably engaged with the end of the transverse plate 45 away from the mounting platform 46 via a slide rail pair 471.

[0042] like Figures 1 to 6As shown, due to the aforementioned structure, the linear drive assembly 47, in conjunction with the slide rail pair 471, enables precise movement of the gripper 42 in three-dimensional space. This allows for flexible adaptation to the positional requirements of different workstation receiving platforms 5, ensuring accurate alignment during workpiece transfer. The top of the newly added support truss 410 slides against the end of the transverse plate 45 away from the mounting platform 46 via the slide rail pair 471, providing additional support constraints for the transverse plate 45. This effectively suppresses the deflection deformation of the transverse plate 45 caused by excessive cantilever length, further improving the movement of the transverse plate 45. The stability and rigidity of the mounting plate 41 ensure the accuracy of the movement trajectory of the gripper 42. The grippers 42, which are arranged at intervals along the straight line on the mounting plate 41, can grasp multiple workpieces at the same time. The groove 49 limits the accommodating position of the gripper 42, preventing the gripper 42 from shaking or interfering, and improving the stability of synchronous material transfer of multiple workpieces. The reinforcing plate 48 effectively enhances the connection rigidity between the mounting plate 41 and the lifting frame 43, alleviates the stress deformation generated after the gripper 42 grasps the workpiece, and further ensures the posture stability of the workpiece during the material transfer process. It is suitable for batch material transfer operations in high-precision assembly scenarios.

[0043] Example 3:

[0044] In this embodiment, in addition to the structural features of the aforementioned embodiments, the linear actuator 472 is a cylinder, the cylinder body is mounted on the longitudinal frame 44, the transverse plate 45 or the mounting platform 46, and the outer end of the piston rod of the cylinder is connected to the lifting frame 43, the longitudinal frame 44 or the transverse plate 45.

[0045] In this embodiment of the application, the longitudinal shifting frame 44 includes a base plate 441, a pair of side plates 442 and a pair of crossbeams 443. The base plate 441 is connected to the bottom of the pair of side plates 442, and the pair of crossbeams 443 are connected to the top of the pair of side plates 442. A through hole 444 is also provided on the base plate 441. A cylinder for driving the lifting frame 43 to rise and fall is installed at the bottom of the base plate 441, and the piston rod passes through the through hole 444 to connect to the lifting frame 43.

[0046] In this embodiment of the application, a pair of guide plates 6 and a pair of guide rods 7 are also included. The pair of guide plates 6 are symmetrically fixed on the inner side wall of the lifting frame 43, and each guide plate 6 has a guide hole longitudinally opened. The pair of guide rods 7 are symmetrically fixed on the base plate 441 and slide through the corresponding guide hole.

[0047] like Figures 1 to 6As shown, due to the above-mentioned structure, the cylinder, as a linear actuator 472, has the advantages of fast response speed, stable power output, and compact structure, which can quickly drive the movement of each moving part and further improve the material transfer cycle. The longitudinal transfer frame 44 adopts a frame structure composed of a base plate 441, side plates 442 and crossbeam 443, which reduces its own weight while ensuring structural strength, reduces the driving load, and takes into account stability and energy saving. The cooperation of the guide plate 6 and the guide rod 7 provides precise guidance for the lifting movement of the lifting frame 43, effectively avoiding the lifting frame 43 from tilting or jamming during the cylinder drive process, ensuring that the gripper 42 always maintains a horizontal posture to pick up and place workpieces, greatly improving the coaxiality and stability of the lifting action. At the same time, the cylinder is hidden at the bottom of the base plate 441, which optimizes the overall layout, avoids interference with other parts, and improves the space utilization of the components.
