DETAILED DESCRIPTION

[0022] (Example 1)

[0023] See Figures 1 to 3 The present embodiment provides a synchronous hooking device for a metal sheet material bin pallet, comprising a main frame 1 and a hooking gripper 2 movably mounted on the main frame 1; hook structures are provided at both ends of the hooking gripper 2, grooves are provided at the bottom of the hooking gripper 2, and the middle portion of the hooking gripper 2 is welded by square tubes, so that the left and right sides of the hooking gripper 2 have the ability to be forced to synchronize, and the pallet will not be skewed due to the unbalanced loading of the goods; a driving mechanism 3 is provided on one side of the main frame 1 for driving the movement of the hooking gripper 2; a guide mechanism 4 is provided on both sides of the hooking gripper 2; the guide mechanism 4 is used to guide the movement of the hooking gripper 2; a support mechanism 5 is provided in the middle portion of the main frame 1; the support mechanism 5 is used to provide transitional support for the moving hooking gripper 2. The present embodiment constructs a complete synchronous hooking system through the coordinated design of the driving mechanism 3, the guide mechanism 4 and the support mechanism 5. The combined action of the guide mechanism 4, the support mechanism 5 and the hooking gripper 2 ensures that the pallet remains stable during movement, effectively solving the problem of stability during synchronous hooking of the metal sheet material bin pallet.

[0024] Furthermore, the drive mechanism 3 includes a drive shaft 3-1 rotatably connected to the main frame 1; a drive motor 3-2 for rotating the drive shaft 3-1; preferably, the drive motor 3-2 is a reduction motor. The drive shaft 3-1 is connected to the hook gripper 2 via a transmission mechanism 6. The combination of the drive shaft 3-1 and the transmission mechanism 6 in this embodiment achieves a modular design for power transmission. The drive motor 3-2 and the transmission mechanism 6 cooperate to convert rotational motion into linear motion of the hook gripper 2, ensuring efficient and controllable power transmission.

[0025] Furthermore, the main frame 1 is provided with a fixed beam 1-1; both ends of the drive shaft 3-1 are rotatably connected to the middle portion of the fixed beam 1-1 via bearing seats 3-3; the drive motor 3-2 is fixedly connected to the fixed beam 1-1; and the drive motor 3-2 is transmission-connected to the middle portion of the drive shaft 3-1 via a first sprocket assembly 3-4. In this embodiment, the fixed beam 1-1 serves as the core load-bearing structure, supporting the drive shaft 3-1 via dual bearing seats 3-3, significantly improving the stability of the drive system. The central placement of the drive motor 3-2 and the first sprocket assembly 3-4 optimizes the symmetry of power transmission and reduces the risk of torque unbalance.

[0026] Furthermore, first support blocks 3-5 are provided on both sides of the fixed beam 1-1, located on either side of the drive motor 3-2. These first support blocks 3-5 are rotatably connected to the drive shaft 3-1. In this embodiment, the first support blocks 3-5 on either side form a multi-point support structure, effectively suppressing radial vibration of the drive shaft 3-1 during high-speed operation. This distributed support design significantly improves the bending stiffness of the drive shaft 3-1 and extends the service life of the bearings.

[0027] Furthermore, the transmission mechanism 6 includes second sprocket assemblies positioned on either side of the main frame 1. The driving sprocket of the second sprocket assembly is fixed to the end of the drive shaft 3-1, and the driven sprocket is rotatably connected to the end of the main frame 1 distal from the drive shaft 3-1. The chain of the second sprocket assembly is fixedly connected to the hook gripper 2. The innovative design of the bilateral second sprocket assemblies in this embodiment achieves synchronous drive. The direct chain connection to the hook gripper 2 ensures strict synchronization of movement on both sides. The placement of the remote driven sprocket optimizes the chain wrap angle and reduces the risk of chain tooth skipping.

[0028] Furthermore, support plates 1-2 are provided on the inner walls on both sides of the main frame 1; the guide mechanism 4 includes a first guide wheel group 4-1, a second guide wheel group 4-2 and a third guide wheel group 4-3; the first guide wheel group 4-1, the second guide wheel group 4-2 and the third guide wheel group 4-3 are rotatably mounted on the end faces on both sides of the hook gripper 2; the first guide wheel group 4-1 and the second guide wheel group 4-2 are respectively located on both sides of the support plate 1-2 and the first guide wheel group 4-1 and the second guide wheel group 4-2 are both in rolling connection with the support plate 1-2; the third guide wheel group 4-3 is rotatably connected to the side wall of the main frame 1. This embodiment adopts a composite guide system formed by three groups of guide wheels, and constructs a three-dimensional motion constraint system through the three-dimensional constraint method of clamping on both sides of the support plate 1-2 + side wall limitation. This multi-directional limitation design effectively suppresses the deflection and torsion of the hook gripper 2 during movement.

[0029] Further, the first guide wheel set 4-1, the second guide wheel set 4-2, and the third guide wheel set 4-3 are each composed of at least two guide wheels. This enhances the fault tolerance of the guiding system. Even if a single guide wheel fails, the guiding function can still be maintained, significantly improving the reliability of the system.

[0030] Further, the individual wheels of the first guide wheel set 4-1 and the second guide wheel set 4-2 are arranged with offset positions. The guide wheels with offset arrangement form an interleaved contact pattern, effectively eliminating the influence of movement clearance on the guiding accuracy and preventing jamming phenomena caused by machining errors.

[0031] Further, the support mechanism 5 includes support rollers 5-1 and second support seats 5-2; the second support seats 5-2 are symmetrically arranged at both ends of the fixed beam 1-1; the support rollers 5-1 are rotatably connected to the tops of the second support seats 5-2, and the symmetrically arranged support rollers 5-1 constitute a continuous support surface, providing intermediate support for the picking gripper 2 during long-stroke movement, avoiding the deformation of the tray caused by the cantilever beam effect, and ensuring the planar accuracy of the picking action.

[0032] Further, the support rollers 5-1 are elastic. The elastic support rollers 5-1 absorb the instantaneous impact load of the tray through deformation, and at the same time match the stiffness requirements of metal plates with different thicknesses, achieving an adaptive support effect and extending the service life of the support system.

[0033] The metal sheet storage tray synchronous picking device of this embodiment is provided with a guiding mechanism 4 and a support mechanism 5. The combined action of the guiding mechanism 4, the support mechanism 5, and the picking gripper 2 ensures the stability of the tray during movement.

[0034] The specific embodiments described above further elaborate on the purpose, technical solutions, and beneficial effects of the present invention. It should be understood that the above are only specific embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the protection scope of the present invention.
