[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0031] like Figures 1 to 5 The preformed stringer transfer device shown includes: a first linear module 1 and a second linear module 2, with several first linear modules 1 arranged in parallel at intervals; the second linear module 2 is located below the first linear modules 1 and is arranged perpendicularly to the first linear modules 1; wherein, the second linear module 2 is provided with several working mechanisms 3 arranged at intervals, the working mechanism 3 includes a suction cup 301 located at the bottom in contact with the workpiece, a connecting piece 302 located above the suction cup 301, and a first stepper motor 303 for controlling the up and down movement of the suction cup 301; the second linear module 2 is slidably connected to the first linear module 1 through a first sliding component 4, and a mechanical zero point is also provided on the second linear module 2 and located between two adjacent working mechanisms 3.

[0032] The implementation process of this utility model is as follows: when the positioning pin 1201 on the moving frame 12 is inserted into the positioning hole 1301 on the positioning frame 13, the suction cup 301 grips the long stringer to be transferred. The first stepper motor 303 controls the lifting of the suction cup 301. Under the control of the second stepper motor 5, the working component 3 makes short-distance adjustments along the length direction of the second linear module 2 according to the mechanical zero point. Finally, under the control of the drive component 401, the working component 3 and the second linear module 2 move together along the first linear module 1. This utility model achieves precise movement of the long stringer in the horizontal and vertical directions by setting the first linear module and the second linear module. At the same time, by setting the mechanical zero point, the positioning accuracy of each working mechanism during the movement is ensured, thereby improving the accuracy of the long stringer transfer. Both the first linear module and the second linear module are driven by stepper motors. By precisely controlling the number of rotation steps and the speed of the stepper motors, the long stringer can be transferred quickly and smoothly. In addition, multiple working mechanisms are set up in parallel, which can transfer multiple long strings at the same time, further improving the transfer efficiency.

[0033] In this invention, the first sliding component 4 includes a drive component 401 disposed above the first linear module 1 and a slide plate 402 disposed along the length direction of the first linear module 1. The slide plate is disposed along the length direction of the first linear module, ensuring that the second linear module (and its working mechanism) can slide smoothly on the first linear module, and that the sliding direction is clear and not easily deviated from the predetermined path.

[0034] As a preferred embodiment of the above embodiment, the drive assembly 401 includes a primary stepper motor 4011, a secondary stepper motor 4012, and a tertiary stepper motor 4013. The primary stepper motor 4011 is disposed above the secondary stepper motor 4012, the secondary stepper motor 4012 is disposed above the first linear module 1, and the tertiary stepper motor 4013 is disposed at one end of the first linear module 1. The combined use of the primary, secondary, and tertiary stepper motors can form a multi-stage drive system, thereby improving the overall drive capability, adapting to different load and speed requirements, and increasing the transmission length.

[0035] In this invention, a second stepper motor 5 is also provided at the lower part of the second linear module 2. The second stepper motor 5 is slidably connected to the second linear module 2 via a second sliding component 6. The provision of the second stepper motor gives the second linear module (and its working mechanism) greater driving flexibility in the vertical direction. By controlling the rotation of the second stepper motor, the height position of the second linear module can be precisely adjusted, thereby achieving precise vertical transfer of the stringer.

[0036] As a preferred embodiment of the above embodiment, the second sliding component 6 includes a slide rail 601 that runs along the length of the second linear module 2 and is disposed on the side wall of the second linear module 2, and a slider 602 that meshes with the slide rail 601 and is fixedly connected to the second stepper motor 5 through a fixing piece 7. The cooperative design of the slide rail and the slider ensures high-precision sliding of the second stepper motor on the second linear module, reduces friction and errors during the sliding process, and improves the overall positioning accuracy and motion stability of the device.

[0037] As a preferred embodiment, the fixing plate 7 extends to the outside and is further provided with a support plate 8, to which the first stepper motor 303 is fixedly connected. By extending the fixing plate to the outside and providing a support plate, a more stable support platform is provided for the first stepper motor. The connection between the support plate and the fixing plate increases the rigidity of the entire structure, enabling the device to maintain its shape and position more stably when subjected to external forces, and making it less prone to deformation or loosening.

[0038] In this invention, a third sliding assembly 9 is also provided on the support plate 8, and the connecting member 302 is slidably connected to the first stepper motor 303 through the third sliding assembly 9. The precise design of the third sliding assembly ensures the stability and accuracy of the connecting member during the sliding process.

[0039] In this invention, a shock-absorbing mechanism is provided between the suction cup 301 and the connecting member 302. The shock-absorbing mechanism includes a shock-absorbing spring and a connecting shaft 10. The shock-absorbing spring is sleeved on the outer ring of the connecting shaft 10, and the suction cup 301 is fixedly connected to the connecting member 302 via the connecting shaft 10. The shock-absorbing mechanism makes the suction cup more stable during the adsorption process. The elasticity of the shock-absorbing spring balances the force on the suction cup in different directions, preventing detachment or displacement due to uneven force, thereby improving the stability and reliability of the equipment.

[0040] As a preferred embodiment, the connecting shaft 10 passes through the connector 302 and is fixedly connected to the connecting shaft 10 by an adjustable nut. The adjustable nut design allows for precise tightening of the connecting shaft, thereby ensuring a secure connection between the connector and the suction cup, which is crucial for preventing loosening, detachment, or gaps, especially under dynamic loads or vibration environments. The adjustable nut provides flexible adjustment functionality, allowing the user to adjust the tightness of the connecting shaft according to actual needs.

[0041] In this invention, a mounting plate 11 is provided at the bottom of the second linear module 2 and perpendicular to it. The mounting plate provides a stable support base for the second linear module, which helps to reduce vibration and shaking generated during operation, thereby improving the stability and reliability of the entire device.
