Description

Technical Field

[0001] This application relates to the field of robotic gripper technology, and more particularly to a silver ingot transfer gripper. Background Technology

[0002] Silver ingots, as the primary form of sale for the precious metal silver, require multiple processes in their production, including melting, casting, cooling, drying, and polishing. In industrial production, the efficiency and safety of the silver ingot transfer process directly affect the stability of the overall production flow and product quality. Currently, silver ingot transfer largely relies on robotic grippers, but these grippers still have many shortcomings.

[0003] Traditional silver ingot transfer fixtures typically only have a single clamping function and lack adaptability to subsequent processing steps. Firstly, traditional claw-like fixtures lack sufficient clamping stability; silver ingots are prone to falling off during transfer due to vibration or shifting center of gravity, causing safety hazards or damage to their appearance. After cooling, silver ingots often retain moisture on their surface. If not dried promptly before polishing, this moisture can form water stains during subsequent polishing or processing, affecting the polishing effect and leading to uneven surface or reduced gloss. Furthermore, silver readily reacts with sulfides and other substances in humid environments to form silver sulfide, a black oxide layer, causing discoloration or loss of metallic luster. However, existing fixtures have a simple design and require additional independent drying equipment, increasing costs and extending the production cycle.

[0004] To address the aforementioned issues, there is an urgent need for a silver ingot transfer fixture that integrates clamping, drying, and stable transfer functions to improve production efficiency, ensure operational safety, and optimize product quality. Utility Model Content

[0030] Traditional silver ingot transfer fixtures typically only have a single clamping function and lack adaptability to subsequent processing steps. Firstly, traditional claw-like fixtures lack sufficient clamping stability; silver ingots are prone to falling off during transfer due to vibration or shifting center of gravity, causing safety hazards or damage to their appearance. After cooling, silver ingots often retain moisture on their surface. If not dried promptly before polishing, this moisture can form water stains during subsequent polishing or processing, affecting the polishing effect and leading to uneven surface or reduced gloss. Furthermore, silver readily reacts with sulfides and other substances in humid environments to form silver sulfide, a black oxide layer, causing discoloration or loss of metallic luster. However, existing fixtures have a simple design and require additional independent drying equipment, increasing costs and extending the production cycle.

[0031] To address the aforementioned issues, this application provides a silver ingot transfer fixture. A square fixture is designed to fit the shape of the silver ingot. A clamping cylinder controls the clamping plates and card plates to hold and lift the ingot. Combined with padding blocks, this effectively ensures the stability of the silver ingot during the transfer process. Air jets and vents are installed on both sides of the clamping plates to dry the cooled silver ingot, improving processing efficiency. Furthermore, the fixture integrates an adsorption device to transfer the silver ingot to a polishing device, reducing the need for a robotic arm and lowering production costs.

[0032] The technical solutions of the embodiments of this application are described in detail below with reference to the accompanying drawings.

[0033] Figure 1 This is a schematic diagram of the structure of the silver ingot transfer fixture shown in the embodiments of this application.

[0034] See Figure 1 A silver ingot transfer fixture, comprising:

[0035] 1. Connecting block; 2. Clamping cylinder; 3. Movable plate; 4. Clamping plate; 5. Air jet assembly; 6. Air pipe; 7. Clamping plate; 8. Air hole; 9. Fixing frame; 10. Negative pressure air pipe; 11. Hydraulic cylinder; and 12. Negative pressure suction cup.

[0036] Connecting block 1 is mounted on the forearm of the robotic arm and is rotated by a servo motor. Clamping cylinder 2 is bolted to the lower center of connecting block 1. Clamping cylinder 2 includes two opposing telescopic cylinders and a telescopic sliding rod. Movable plate 3 is bolted to the telescopic rods and sliding rods on both sides of clamping cylinder 2. Clamping plate 4 is bolted to the lower end of movable plate 3. Two clamping plates 7 are respectively installed at the bottom of clamping plate 4 to support the silver ingot. Pads are installed on the inner side of clamping plate 4 above clamping plates 7 to better clamp the silver ingot.

[0037] The jet assembly 5 is installed on the outside of the clamping plate 4. The jet assembly 5 is connected to the high-pressure air pipe of the robot arm on the connecting block 1 through the air pipe 6. The clamping plate 4 is provided with air holes 8 corresponding to the air nozzles of the jet assembly 5. The jet assembly 5 and air holes 8 on both sides of the clamping plate 4 are respectively aligned with the two sides of the silver ingot to dry the cooled silver ingot.

[0038] The adsorption device is installed on the upper front side of the connecting block 1. The adsorption device includes a fixing frame 9, a negative pressure air pipe 10, a hydraulic cylinder 11, and a negative pressure suction cup 12. The fixing frame 9 is installed in the groove at the front end of the connecting block 1, with an upward tilt. The fixing frame 9 faces away from the air cylinder 2, movable plate 3, and clamping plate 4. The hydraulic cylinder 11 is installed on the fixing frame 9, and a universal joint is provided at the top of the piston of the hydraulic cylinder 11. The negative pressure suction cup 12 is installed on the piston of the hydraulic cylinder 11 through the universal joint. The negative pressure air pipe 10 on the negative pressure suction cup 12 is connected to the negative pressure system pipeline of the robotic arm on the connecting block 1. After the silver ingot is dried, the connecting block 1 is rotated to align the negative pressure suction cup 12 with the silver ingot for adsorption, transferring it to the polishing device for polishing.

[0039] In this application, a robotic arm moves the silver ingot transfer fixture above the silver ingot conveyor belt, aligning the clamping plate 4 with the silver ingot on the platform at the tail of the conveyor belt. The clamping cylinder 2 retracts to clamp the silver ingot, and the bottom of the ingot is held in place by the clamping plate 7, transferring the ingot to a cooling pool for cooling. After cooling, the ingot is removed and moved to a placement platform above the cooling pool. The high-pressure air valve is opened, and the jet assembly 5 is activated to blow air onto the cooled silver ingot for drying. After drying, the connecting block 1 is rotated by a servo motor on the robotic arm, moving the robotic arm so that the negative pressure suction cup 12 of the adsorption device aligns with the cooled silver ingot. The negative pressure device is activated, causing the negative pressure suction cup 12 to adsorb the silver ingot, which is then transferred by the robotic arm to a polishing device for grinding and polishing.

[0040] The various embodiments of this application have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
