Description

Technical Field

[0001] This utility model relates to the field of handling fixture technology, specifically a scratch-resistant handling fixture for finished zinc ingots. Background Technology

[0002] Zinc ingots are an alloy produced through a smelting process. In this process, high-purity zinc is melted and mixed with other metals such as copper and aluminum. After precise proportioning and smelting of various metal raw materials, the molten metal is poured into molds and formed into a specific shape through casting or pressing. The demolded zinc ingots are typically long trapezoidal or rectangular blocks of metal. After cooling, they are transported to the production line and stacked mechanically.

[0003] Mechanical handling of finished zinc ingots involves combining robotic arms and clamps on the production line to automate the handling and stacking of zinc ingots. Because the surface of finished zinc ingots is relatively smooth, the clamps require two sets of clamps to exert significant pressure on the ingots during handling. Furthermore, prolonged operation causes wear on the inner walls of the clamps, potentially resulting in burrs. This wear can easily scratch the surface of the zinc ingots during handling. Additionally, if the power source or connection of the clamps malfunctions, the gripping force of the jaws may suddenly change, potentially causing the ingot to slip off the jaws and resulting in scratches on the ingot's surface, thus affecting the production quality of the zinc ingots.

[0004] To address this problem, the present invention provides a scratch-resistant handling clamp for finished zinc ingots. Utility Model Content

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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. Example 1

[0016] Please see Figure 1-4 A scratch-resistant handling clamp for finished zinc ingots includes a connecting frame 1, a transport clamp 2 symmetrically and slidably connected to the bottom of the connecting frame 1, a driving component 3 installed between the connecting frame 1 and the transport clamp 2, and a fastener 4 installed on the outside of the transport clamp 2. The fastener 4 includes a slot 401 symmetrically opened inside the transport clamp 2. A movable clamp 402 is installed inside the slot 401. Limiting rods 403 are symmetrically installed between the transport clamp 2 and the movable clamp 402. An air bag 404 is fixedly connected to one side of the movable clamp 402. An air pump 405 is fixedly connected to the outside of the transport clamp 2. An air tube 406 is fixedly connected between the air bag 404 and the air pump 405.

[0017] The bottom cross-section of transport clamp 2 is L-shaped.

[0018] In this embodiment, after the zinc ingot is detached and cooled in the cooling chamber, the production line transports the zinc ingot to the handling area. The handling of the finished zinc ingot is accomplished by a robotic arm driving a clamp. During handling, the robotic arm moves the connecting frame 1 above the transport production line. The two transport clamps 2 at the bottom of the connecting frame 1 unfold. After the two transport clamps 2 move above the finished zinc ingot, they close and clamp from both ends of the zinc ingot. The clamping force of the two transport clamps 2 decreases. Since the bottom cross-section of the transport clamps 2 is L-shaped, the two transport clamps 2 lift the zinc ingot from the bottom, so that the zinc ingot is between the two transport clamps 2. At this time, the air pump 40... 5. Air is injected into the airbag 404 through the air tube 406, causing the airbag 404 to inflate. The inflated airbag 404 matches the shape of both ends of the zinc ingot, thus achieving the effect of fixing and clamping the airbag 404. Due to the soft texture of the airbag 404, the method of using the airbag 404 to clamp the zinc ingot, compared with the direct clamping method of the metal transport clamp 2, prevents the transport clamp 2 from exerting excessive pressure on the zinc ingot, which could cause damage to the edge of the zinc ingot. At the same time, the fixed clamping method of the airbag 404 prevents the two sets of transport clamps 2 from malfunctioning during the handling of the zinc ingot, which could cause the transport clamp 2 and the zinc ingot to slip off, and prevents the transport clamp 2 from scratching the zinc ingot.

[0019] A drive component 3 is installed between the connecting frame 1 and the transport clamp 2. The drive component 3 includes a servo motor 301 symmetrically fixedly connected to the top of the connecting frame 1. A worm gear 302 is fixedly connected to the output end of the servo motor 301. A worm 303 is rotatably connected inside the connecting frame 1. The worm gear 302 and the worm 303 mesh with each other. A lead screw 304 is fixedly connected to one end of the worm 303. The lead screw 304 is installed inside the connecting frame 1 and threadedly connected to the transport clamp 2.

[0020] In this embodiment, when the two sets of transport clamps 2 clamp the zinc ingot from both ends, the two sets of servo motors 301 are connected in a linkage manner. The two sets of servo motors 301 simultaneously drive the worm gears 302 fixed at their output ends to rotate inside the connecting frame 1. The rotating worm gears 302 drive the lead screw 304 connected to the worm 303 to rotate. The rotating lead screw 304 drives the transport clamps 2 connected to its outer thread to move at the bottom of the connecting frame 1. The two transport clamps 2 achieve the initial clamping and fixing of the zinc ingot.

[0021] On the other side of the transport clamp 2, a movable component 5 is installed. The movable component 5 includes a dual-axis motor 501 fixedly connected to the outside of the transport clamp 2. Both output ends of the dual-axis motor 501 are fixedly connected to screws 502. A hinge seat 503 is fixedly connected to the back side of the movable clamp 402. The hinge seat 503 is located inside the slot 401. Rotating rods 504 are symmetrically installed inside the hinge seat 503. One end of the rotating rod 504 is hinged to a threaded seat 505. The threaded seat 505 and the screw 502 are threadedly connected.

[0022] The screw 502 and the two rotating rods 504 are arranged in a triangular structure. The outer side of the screw 502 is provided with two sets of threads, which are arranged in the same direction.

[0023] In this embodiment, before using the airbag 404 to clamp and fix both ends of the zinc ingot, the screws 502 at both ends of the dual-axis motor 501 rotate simultaneously. The two rotating screws 502 drive the two threaded seats 505 on their outer sides to move in opposite directions, so that the moving clamp 402 moves inside the slot 401. The moving clamp 402 drives the airbag 404 to further clamp and fix both ends of the zinc ingot, improving the stability of the zinc ingot during the handling process.

[0024] The top of the connecting bracket 1 is fixedly connected to the connecting seat 6.

[0025] In this embodiment, the connecting seat 6 is used to connect with the robotic arm to realize operations such as angle rotation and movement of the connecting frame 1.

[0026] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0027] Working principle: Before handling the finished zinc ingots, the connecting seat 6 at the top of the connecting frame 1 is first connected to the robotic arm. After the zinc ingots are detached and cooled, they are transported to the handling area by the conveyor belt. At this time, the connecting frame 1 drives the transport clamps 2 to descend, and at the same time, the servo motor 301 drives the worm gear 302 fixed at its output end to rotate. Simultaneously, the worm gear 302 drives the lead screw 304 connected to the worm 303 to rotate. At this time, the two transport clamps 2 move in opposite directions and unfold. The two unfolded transport clamps 2 correspond to the positions of the zinc ingots at the top of the conveyor belt. When the two transport clamps 2 move to the zinc ingot... After the zinc ingot is lifted, the connecting frame 1 descends, and the L-shaped transport clamps 2 at the bottom align with the two ends of the zinc ingot. At this time, the servo motor 301 drives the two transport clamps 2 to move in opposite directions again, lifting the zinc ingot from both ends. The transport clamps 2 exert a relatively small squeezing force on the zinc ingot to prevent excessive squeezing force from causing wear on the edges of the zinc ingot. At the same time, the two transport clamps 2 mainly complete the handling operation of the finished zinc ingot, assisting in the clamping of the zinc ingot, and also preventing excessive squeezing force from causing wear on the transport clamps 2. After the two transport clamps 2 lift the zinc ingot, the transport clamps... 2. The dual-axis motor 501 on the outer side drives the screw 502 to rotate. The rotation of the screw 502 causes the threaded seat 505 on the outer side of the screw 502 to move in opposite directions. Through the rotation of the rotating rod 504, the movable clamping piece 402 extends out from the inside of the slot 401. At the same time, the air bladder 404 on the outer side of the movable clamping piece 402 abuts against both ends of the zinc ingot. Because the air bladder 404 is soft, it prevents the edge of the zinc ingot from being scratched or worn. After the two movable clamping pieces 402 have further clamped and fixed the zinc ingot, the air pump 405 injects air into the air bladder 404 through the air pipe 406. The inflated air... The shape of the air bag 404 matches the two ends of the zinc ingot, thus re-clamping and fixing the zinc ingot to prevent it from loosening during transportation and to prevent it from being scratched. After the robotic arm moves the zinc ingot to the stacking position, the air pump 405 draws air, the air bag 404 contracts, and at the same time the dual-axis motor 501 drives the screw 502 to rotate, causing the moving clamp 402 to separate from the zinc ingot. Furthermore, the servo motor 301 rotates the lead screw 304 to make the two transport clamps 2 move in opposite directions, thereby separating the zinc ingot from the transport clamps 2, and the zinc ingot falls to the stacking position.
