Description

Technical Field

[0001] This utility model relates to the field of precious metal processing technology, and in particular to a precious metal forming device. Background Technology

[0002] In the field of precious metal processing, the transfer of precious metals is a crucial step in the production process. In this step, precious metals are typically melted in a crucible. After the precious metals are completely melted in the crucible, workers must use tongs to remove the crucible from the furnace and quickly pour the molten precious metal into a precious metal forming mold. However, this process is currently entirely manual, presenting several problems that urgently need to be addressed. First, due to the extremely high temperatures after the precious metals melt, workers must wear heavy protective gear, which not only increases their workload but also reduces operational flexibility. Prolonged work in high-temperature environments easily leads to worker fatigue and reduces operational efficiency. This reduced efficiency becomes a key factor limiting the improvement of overall transfer efficiency, especially when dealing with large volumes of precious metals. Furthermore, manual operation poses significant safety hazards. In high-temperature environments, workers are in close contact with molten precious metals and high-temperature furnaces; improper operation can easily lead to burns and other accidents, posing a serious threat to their health. With the continuous development of industrial automation technology, more and more production processes are introducing automated equipment to improve production efficiency. Therefore, developing an automated device that can automatically remove the crucible from the furnace and pour the molten precious metal into a precious metal forming mold has become a technical problem that urgently needs to be solved by those skilled in the art.

[0019] Please see Figure 1-4As shown, in one embodiment of this utility model, a precious metal forming device includes a base 10, a crucible 20, a clamping mechanism, and a robotic arm mechanism 40. The crucible 20 includes a body 21 and a receiving groove disposed within the body 21. The body 21 has an arc-shaped outer wall. The receiving groove of the crucible 20 is used to hold precious metal. The crucible 20 is placed in a furnace for melting. The clamping mechanism includes a driving assembly 50 disposed on the base 10 and two clamps 30. Each clamp 30 is provided with a clamping part 31. The clamping part 31 is provided with a clamping groove 310. The clamping groove 310 includes a first clamping groove wall 3100 arranged at a preset angle and a... The second clamping groove wall 3101, the angle between the first clamping groove wall and the second clamping groove wall is between 130 degrees and 140 degrees, preferably, the angle between the first clamping groove wall and the second clamping groove wall is 135 degrees, the two clamps 30 are arranged adjacent to each other at one end of the clamping part 31, the driving assembly 50 drives the clamping part 31 in the two clamps 30 to move closer or further away from each other, so as to clamp or release the body 21 with the arc-shaped outer wall through the two clamping grooves 310, the robotic arm mechanism 40 is connected to the base 10, the robotic arm mechanism 40 drives the gripping mechanism to pick up the crucible 20 from the furnace and pour the molten precious metal into the forming mold.

[0020] In the above scheme, the robotic arm mechanism 40 drives the gripping mechanism to complete the removal of the crucible 20 from the furnace and subsequent operations. Workers do not need to directly contact the high-temperature area, effectively avoiding the risk of burns and protecting worker health. The robotic arm mechanism 40 can stably and accurately execute operations according to a preset program, unaffected by fatigue or other factors, greatly reducing the probability of accidents caused by human error. The robotic arm mechanism 40 and the gripping mechanism can quickly and efficiently complete the gripping, transfer, and pouring of precious metals into the crucible 20, significantly improving operational efficiency. Especially when facing large-scale precious metal circulation demands, it can effectively improve circulation efficiency, meet production needs, and is unaffected by human factors. It enables continuous and automated production of precious metal forming processes, further improving production efficiency. The clamping part 31 of the gripping mechanism is provided with a clamping groove 310, which includes a first clamping groove wall 3100 and a second clamping groove wall 3101 arranged at a preset angle. This allows for close contact with the arc-shaped outer wall of the crucible 20, ensuring stability and reliability during gripping. The clamping mechanism of this device can more firmly clamp the crucible 20, avoiding wobbling or falling off due to unstable clamping, and ensuring smooth operation. The robotic arm mechanism 40 is connected to the base 10, enabling precise control of the clamping mechanism's movement trajectory and achieving accurate positioning from the furnace to the forming mold. This device ensures that the molten precious metal is accurately poured into the forming mold, reducing waste of precious metal or forming defects caused by inaccurate pouring, and improving product quality and consistency. Please refer to [link / reference]. Figure 1-4As shown, in this embodiment, the robotic arm mechanism 40 is a six-axis robot, which includes a robotic hand 41 connected to the base 10. The six-axis robot has six degrees of freedom, enabling omnidirectional movement and posture adjustment. During the precious metal forming process, it can flexibly approach the furnace, crucible 20, and forming mold from different angles and positions, easily handling various complex operating scenarios. For example, in space-constrained production environments, it can flexibly avoid obstacles and accurately complete operations such as gripping and transferring the crucible 20 and pouring precious metals. In other embodiments, the robotic arm mechanism 40 can be selected with other drive mechanisms, such as a linear module robotic hand, depending on actual needs.

[0021] Please see Figure 1-4 As shown, in one embodiment of this utility model, the crucible 20 further includes a first annular protrusion 22 disposed on the body 21. The chuck 30 has a limiting portion 32 at one end of the clamping portion 31. A limiting groove 320 is provided within the limiting portion 32, and the opening direction of the limiting groove 320 is consistent with the opening direction of the clamping groove 310. When the body 21 is clamped by the clamping groove 310, the first annular protrusion 22 is placed within the limiting space formed by the limiting grooves 320 of the two limiting portions 32. When the clamping portion 31 of the chuck 30 clamps the body 21 of the crucible 20 through the clamping groove 310, the first annular protrusion 22 is precisely placed within the limiting space formed by the limiting grooves 320 of the two limiting portions 32, enabling precise positioning and fixation of the crucible 20. The opening direction of the limiting groove 320 is consistent with the opening direction of the clamping groove 310, so that while the chuck 30 clamps the crucible 20, the limiting part 32 can provide additional support and constraint from the side, preventing the crucible 20 from shaking or shifting during the clamping process, thereby significantly enhancing the stability of the clamping.

[0022] Please see Figure 1-4As shown, in one embodiment of this utility model, the crucible 20 further includes a second annular protrusion 23 disposed on the body 21. There are two limiting portions 32, which are arranged correspondingly on both sides of the clamping portion 31 on the chuck 30. One of the chucks 30 has two limiting portions 32 arranged opposite each other to limit the first annular protrusion 22, and the other chuck has two limiting portions 32 arranged opposite each other to limit the second annular protrusion 23. By providing a first annular protrusion 22 and a second annular protrusion 23 on the crucible 20 body 21, and limiting the two annular protrusions respectively on the chuck 30, a double limiting structure is formed. The double limiting can fix and constrain the crucible 20 from two different positions, significantly enhancing the stability and reliability of the clamping. Even if there is significant vibration or impact during rapid movement of the robotic arm or operation, the crucible 20 is not easily shaken or falls off, ensuring the safety and stability of the operation process. Furthermore, the limiting groove 320 is a trapezoidal limiting groove 320. The shape of the trapezoidal limiting groove 320 provides more stable support when clamping the crucible 20.

[0023] Please see Figure 1-4 As shown, in one embodiment of this utility model, the drive assembly 50 includes a drive member 51 disposed on the base 10 and two lifting arms 52 disposed on the drive member 51. Each lifting arm 52 includes a mounting end 520 and a cantilever end 521. The mounting end 520 is connected to the drive member 51, and the cantilever end 521 is connected to the chuck 30. The drive member 51, mounted on the base 10, provides a stable power source for the clamping mechanism. By adding the lifting arms 52, a certain distance is maintained between the drive member 51 and the furnace, effectively reducing the operating temperature of the drive member 51 and minimizing damage to its internal components due to high temperatures, thereby extending the service life of the drive member 51.

[0024] Please see Figure 1-4 As shown, in one embodiment of this utility model, the cantilever end 521 is provided with a mounting groove 5210, and the chuck 30 is disposed in the mounting groove 5210. The two oppositely arranged outer sidewalls of the chuck 30 abut against the two oppositely arranged inner sidewalls of the mounting groove 5210. The tight abutment between the chuck 30 and the mounting groove 5210 forms a stable mechanical connection, effectively preventing the chuck 30 from loosening or shifting during operation. This ensures the reliability of the chuck 30 when gripping and transferring the crucible 20, and improves the stability of the entire gripping mechanism.

[0025] Please see Figure 1-4As shown, in one embodiment of this utility model, the driving component 51 is a clamping cylinder, which includes two relatively movable parts 510, each of which is connected to one of the two lifting arms 52. The driving component 51 uses a clamping cylinder, and the clamping cylinder includes two relatively movable parts 510, which are respectively connected to one of the two lifting arms 52, thereby enhancing the stability and reliability of the clamping operation.

[0026] Please see Figure 1-4 As shown, in one embodiment of this utility model, the base 10 is further provided with an anti-sway component 60. The anti-sway component 60 includes a guide rail 61, two sliders 62, and two connecting blocks 63. The guide rail 61 is disposed on the base 10, the two sliders 62 are disposed on the guide rail 61 and simultaneously slidably connected to the guide rail 61, and the two connecting blocks 63 are correspondingly disposed on the two sliders 62, and the two connecting blocks 63 are correspondingly connected to the two lifting arms 52. During the process of gripping and transferring the crucible 20, the movement of the robotic arm may cause the gripping mechanism to shake or vibrate. The anti-sway component 60, through the sliding connection of the guide rail 61 and the sliders 62, can effectively limit the unintended movement of the lifting arms 52, reduce shaking and vibration, and ensure the stability of the gripping operation. Furthermore, the anti-sway component 60 includes two sets, the two sets of anti-sway components 60 are respectively disposed on both sides of the drive member 51, and the two sets of anti-sway components 60 are correspondingly connected to both ends of the lifting arms 52. By setting anti-sway components 60 on both sides of the drive component 51 and connecting them one by one to the two ends of the boom 52, the stability of the crucible 20 clamping operation is further improved.
