Description

Technical Field

[0001] This utility model relates to the field of screw fastening equipment, and in particular to a large-span anti-vibration fastening equipment for battery packs. Background Technology

[0002] Screw fastening equipment typically features a three-axis linear module (x, y, z), meaning an x-axis module mounts a y-axis module, and the y-axis module mounts a z-axis module. This overlapping structure has poor stability, and when the electric screwdriver's torque is overloaded, stress is applied to the x, y, and z linear modules. As a result, the electric screwdriver mounted on the z-axis module will swing. The longer the module's stroke, the more pronounced the swinging phenomenon, leading to inaccurate visual positioning. Due to this inaccuracy, if the accuracy threshold is exceeded, the equipment will stop during the screw fastening process to reset and recalibrate the positioning, severely reducing work efficiency. Utility Model Content

[0003] The main technical problem solved by this utility model is to provide a large-span anti-vibration locking device for battery packs. By constructing a gantry structure and constructing a multi-stage energy absorption design on the stress transmission path, the whole machine forms a good vibration reduction effect, which in particular effectively enhances the stability of visual positioning, improves the reliability of screw locking, and increases the working efficiency of screw locking.

[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: providing a battery pack large-span anti-vibration locking device, including a cabinet, a vibration damping platform, an XYZ three-axis linear module, and locking electric screwdrivers. A conveying channel is set in the center of the cabinet, and vibration damping platforms are set along both sides of the conveying channel. Two sets of adjacent XYZ three-axis linear modules are mounted on the vibration damping platform. The XYZ three-axis linear modules span the conveying channel in a gantry structure. Each XYZ three-axis linear module is equipped with a set of locking electric screwdrivers. Square tube supports are set at both ends of the vibration damping platform, and threaded lifting supports are set between the square tube supports. The threaded lifting supports support the bottom of the vibration damping platform.

[0005] In a preferred embodiment of this utility model, the XYZ three-axis linear module is formed by overlapping the x-axis servo module, the y-axis servo module and the z-axis servo module to form a gantry structure. The y-axis servo module is arranged in parallel on the shock-absorbing platform along the conveying channel. A gantry frame is erected between the y-axis servo modules, and the x-axis servo module is arranged on the gantry frame.

[0006] In a preferred embodiment of this utility model, the gantry frame is composed of an x-axis back plate, an upper x-axis crossbeam, and a lower x-axis crossbeam. The two ends of the x-axis back plate are mounted on the y-axis servo module. The upper x-axis crossbeam and the lower x-axis crossbeam are aligned and installed on the upper and lower edges of the x-axis back plate. Fastening mounting holes are evenly provided on the upper x-axis crossbeam and the lower x-axis crossbeam. Spring bolts for locking the x-axis back plate are provided in the fastening mounting holes. The spring bolts are used to absorb large-span resonant stress in the x-axis direction.

[0007] In a preferred embodiment of this utility model, the threaded lifting support is used to absorb large-span resonant stress in the y-axis direction.

[0008] In a preferred embodiment of this utility model, the cabinet is further provided with several rotary pressing cylinders on both sides of the conveying channel. A horizontal swing arm is installed on the rotary pressing cylinder, and a rubber-coated pressure block is provided at the front end of the horizontal swing arm. The rubber-coated pressure block is used to absorb the resonance stress caused by the locking electric screwdriver and reduce the resonance stress transmitted to the XYZ three-axis linear module.

[0009] The beneficial effects of this utility model are as follows: The battery pack large-span anti-vibration locking device provided by this utility model, by constructing a gantry structure and constructing a multi-stage energy absorption design on the stress transmission path, makes the whole machine form a good shock absorption effect, especially effectively enhancing the stability of visual positioning, improving the reliability of screw locking, and increasing the working efficiency of screw locking.

Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0015] like Figure 1-3 As shown, the embodiments of this utility model include:

[0016] A battery pack large-span anti-vibration locking device includes a cabinet 1, a vibration damping platform 2, an XYZ three-axis linear module 3, and a locking electric screwdriver 4. The cabinet 1 has a central conveying channel 5. Vibration damping platforms 2 are arranged along both sides of the conveying channel 5. Two sets of adjacent XYZ three-axis linear modules 3 are mounted on the vibration damping platform 2. The XYZ three-axis linear modules 3 span the conveying channel 5 in a gantry structure. Each XYZ three-axis linear module 3 is equipped with a set of locking electric screwdrivers 4. Square tube supports 6 are arranged at both ends of the vibration damping platform 2. Threaded lifting supports 7 are also arranged between the square tube supports 6, and the threaded lifting supports 7 support the bottom of the vibration damping platform 2.

[0017] The XYZ three-axis linear module 3 is formed by the interconnection of the x-axis servo module 8, the y-axis servo module 9 and the z-axis servo module 10 to form a gantry structure. The y-axis servo module 9 is arranged in parallel on the shock-absorbing platform 2 along the conveying channel 5. A gantry frame 11 is erected between the y-axis servo modules 9, and the x-axis servo module 8 is arranged on the gantry frame 11.

[0018] Furthermore, the gantry frame 11 is composed of an x-axis backplate 12, an x-axis upper crossbeam 13, and an x-axis lower crossbeam 14. The two ends of the x-axis backplate 12 are mounted on the y-axis servo module 9. The x-axis upper crossbeam 13 and the x-axis lower crossbeam 14 are aligned and installed on the upper and lower edges of the x-axis backplate 12. Fastening mounting holes 15 are evenly provided on the x-axis upper crossbeam 13 and the x-axis lower crossbeam 14. Spring bolts for locking the x-axis backplate 12 are provided in the fastening mounting holes 15. The spring bolts are used to absorb large-span resonant stress in the x-axis direction.

[0019] Furthermore, the threaded lifting support 7 is used to absorb large-span resonant stress in the y-axis direction.

[0020] Furthermore, the cabinet 1 is also provided with several rotary pressing cylinders 16 on both sides of the conveying channel 5. A horizontal swing arm 17 is installed on the rotary pressing cylinder 16. A rubber-coated pressure block 18 is provided at the front end of the horizontal swing arm 17. The rubber-coated pressure block 18 is used to absorb the resonance stress caused by the locking electric screwdriver 4 and reduce the resonance stress transmitted to the XYZ three-axis linear module 3.

[0021] The locking electric screwdriver 4 is equipped with a visual positioning camera 20.

[0022] To address the problems existing in the current technology, this equipment employs an XYZ three-axis linear module 3 to construct a gantry structure spanning the conveying channel 5, which can initially suppress the swinging phenomenon at the end of the Z-axis. In addition, this equipment further adds a threaded lifting support column 7 to provide rigid support for the shock-absorbing platform 2, absorbing most of the stress and further absorbing the stress transmitted to the XYZ three-axis linear module 3.

[0023] However, since the XYZ three-axis linear module 3 still has a slight sway, this equipment further adds spring bolts to fix the upper crossbeam 13 and the lower crossbeam 14 of the x-axis to the x-axis back plate 12. The spring bolts are ordinary bolts with springs inserted to lock them to the x-axis back plate 12. This can further reduce the stress significantly and completely suppress the sway phenomenon.

[0024] Meanwhile, taking into account the vacuum effect in the near field of the bit, this equipment also adds several rotating downward pressing cylinders 16 to press the battery pack, which plays a certain auxiliary role in shock absorption.

[0025] In summary, this utility model provides a large-span anti-vibration locking device for battery packs. By constructing a gantry structure and incorporating a multi-stage energy absorption design along the stress transmission path, the entire machine achieves a good vibration reduction effect. In particular, it effectively enhances the stability of visual positioning, improves the reliability of screw locking, and increases the working efficiency of screw locking.

Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
