Description

Technical Field

[0001] This utility model relates to the field of gripper technology, specifically a multifunctional product gripper mechanism. Background Technology

[0002] A gripper is a mechanical device widely used in various automation, robotic, industrial, and everyday grasping and holding operations. Its basic function is to grasp or hold objects through its gripping parts for handling, fixing, or manipulation. However, existing gripper mechanisms still have certain shortcomings in use, such as...

[0003] Existing product gripper mechanisms typically use flat or curved notches for their clamping plates, which need to be replaced according to the product's shape. Most of these mechanisms are not interchangeable and have poor adaptability. Furthermore, most existing product gripper mechanisms only use rubber pads to buffer the clamping force. However, the gripper retracts relatively quickly, and buffering with only rubber pads is ineffective and can easily damage the product. Moreover, the buffering force cannot be adjusted according to different products. Utility Model Content

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Please see Figures 1-3 This utility model provides a technical solution: a multi-functional product gripper mechanism, including: a support base 1, a large servo motor 2, a mounting plate 3, and a drive assembly 4;

[0027] A large servo motor 2 is installed inside the support base 1. The output end of the large servo motor 2 is connected to the mounting plate 3 via a coupling. A drive assembly 4 is connected to the outside of the mounting plate 3. A vertical plate 5 is provided inside the drive assembly 4. A groove 6 is provided on one side of the vertical plate 5. A buffer assembly 7 is provided inside the vertical plate 5. A limit assembly 8 is provided inside the groove 6. The drive assembly 4 includes: a housing 401, a small servo motor 402, a gear 403, a toothed plate 404, and a slide rod 405. The housing 401 is bolted to the outside of the mounting plate 3. The small servo motor 402 is connected to the inner wall of the housing 401 via a motor mount. The output end of the small servo motor 402 is connected to the gear 403 via a coupling through the inner wall of the housing 401. The front and rear parts of the gear 403 are meshed with the toothed plate 404. A slide rod 405 is connected to the inner wall of the housing 401 near the toothed plate 404.

[0028] In practice, the small servo motor 402 is started to drive the gear 403 to rotate. The gear 403 drives the two sets of toothed plates 404 to move in opposite directions, pushing the upright plate 5 to slide along the slide bar 405 to clamp the product.

[0029] See Figures 1-4 It is known that the limiting component 8 includes: a square rod 801, a rubber pad 802, a threaded rod 803, a worm gear 804, and a worm 805. The square rod 801 is slidably connected to the inner wall of the groove 6. The rubber pad 802 is connected to one side of the rubber pad 802 by glue. The side of the square rod 801 away from the rubber pad 802 is threadedly connected to the threaded rod 803 by a threaded groove. The threaded rod 803 is rotatably connected to one side of the inner wall of the groove 6 by a bearing. The worm gear 804 is connected to the outer side of the threaded rod 803. The worm gear 804 is located on one side of the square rod 801. The worm 805 is meshed and connected above the worm gear 804. The worm 805 passes through and rotates in the front part of the inner wall of the groove 6.

[0030] In practice, the rotating worm 805 drives the worm wheel 804 to rotate, and the worm wheel 804 drives the threaded rod 803 to rotate inside the square rod 801, thereby causing the square rod 801 to slide inside the groove 6. The position of the square rod 801 inside the groove 6 is adjusted, and the positions of multiple sets of square rods 801 are adjusted in sequence so that multiple sets of rubber pads 802 can abut against the surface of the product, so that the product gripper mechanism can adapt to different products.

[0031] See Figures 1-5 It is known that the buffer assembly 7 includes: a damper 701, a telescopic rod 702, a spring 703, a retaining ring 704, a crossbar 705, a circular plate 706, and a threaded handle 707. The damper 701 is bolted between the vertical plate 5 and the trough 6. The telescopic rod 702 is bolted between the vertical plate 5 away from the damper 701 and the trough 6. The spring 703 is sleeved on the outside of the telescopic rod 702. The retaining ring 704 abuts against one side of the spring 703. The retaining ring 704 is slidably connected to the telescopic rod 702. The crossbar 705 is connected to the side of the retaining ring 704 away from the spring 703. The crossbar 705 slides through the interior of the vertical plate 5. The circular plate 706 is connected to one side of the crossbar 705. The threaded handle 707 is threadedly connected to the inside of the circular plate 706. The threaded handle 707 is rotatably connected to one side of the vertical plate 5.

[0032] In practice, rotating the threaded handle 707 moves the circular plate 706, which in turn moves the crossbar 705 within the vertical plate 5. The crossbar 705 pushes the retaining ring 704 to slide outside the telescopic rod 702, compressing the spring 703 and adjusting the buffering force. When clamping the product, the groove 6 compresses the damper 701 and the spring 703 to buffer and prevent deformation during clamping, thus allowing the product gripper mechanism to buffer the clamped product.

[0033] In summary: When using this multi-functional product gripper mechanism, firstly, the support base 1 is fixed to the robotic arm with bolts and connected to the control system with cables. The small servo motor 402 is started to drive the gear 403 to rotate. The gear 403 drives the toothed plate 404 to push the vertical plate 5 along the slide rod 405, clamping a product sample. Then, according to the product's shape, multiple sets of worm gears 805 are rotated to adjust the positions of multiple sets of rubber pads 802, allowing the rubber pads 802 to abut against the product. Then, according to the product's rigidity, the threaded handle 707 is rotated to drive the retaining ring 704 to compress the spring 703, adjusting the buffering force of the groove 6. Then, the mechanism is started. The small servo motor 402 rotates in reverse to remove the product sample. The robotic arm then moves the product gripper mechanism to the product that needs to be transferred. The small servo motor 402 is activated to move the rubber pad 802, which is pressed onto the product. The robotic arm then places the gripped product onto another device and activates the small servo motor 402 to rotate in reverse to lower the product. When multiple transfers are required simultaneously, the large servo motor 2 is activated to rotate the mounting plate 3, which moves the rubber pads 802 in other arrangements downwards to grip the product. Any content not described in detail in this specification is prior art known to those skilled in the art.

[0034] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
