Description

Technical Field

[0001] The utility model relates to the technical field of semiconductors, in particular to a rod demoulding auxiliary device. Background Art

[0002] Tantalum metal and its compounds are widely used in coating technologies in the semiconductor industry (such as wafer and chip manufacturing) and the electronics industry due to their advantages such as high conductivity, thermal stability and corrosion resistance. Tantalum targets have gradually become one of the key raw materials in the semiconductor industry. Sputtering tantalum targets mainly involves two main processes: smelting and plastic processing. The smelting method mainly adopts vacuum electron beam melting; electron beam furnace melting usually uses metal bars, and its forming usually adopts cold isostatic pressing. Tantalum powder is filled into a fixed mold. After the mold is sealed, it is placed in a cold isostatic press and pressed into shape by pressure. The operator demolds the formed tantalum bar blank. After successful demolding, the tantalum bar blank is calcined in a high vacuum sintering furnace to become a sintered tantalum bar. The sintered tantalum bar is purified by subsequent electron beam furnace melting to obtain tantalum ingots, which become the main material for making tantalum targets.

[0003] At present, operators are usually required to manually demold tantalum rod blanks. However, after cold isostatic pressing, each tantalum rod blank is heavy and has irregular edges and corners. It is time-consuming and laborious for operators to pull out the tantalum rod, and the tantalum rod blank is easily damaged by falling. Due to the irregular edges and corners around the tantalum rod blank, the mold can be easily damaged after it falls, affecting the subsequent use of the mold. There is also a risk of injuring the operator, posing a major safety hazard. Utility Model Content

[0031] Please refer to Figures 1 to 2As shown, the utility model provides a rod demoulding auxiliary device, which can automatically assist the rod 100 in demoulding, prevent the rod 100 from falling, improve the safety and efficiency of the demoulding operation, and reduce manpower dependence. The rod demoulding auxiliary device is used to assist the rod 100 in demoulding, and includes a loading platform 1, an unloading platform 2 and a demoulding component 3, wherein the unloading platform 2 is located below the loading platform 1, the loading platform 1 is used to convey the rod 100 to be demoulded, and the unloading platform 2 is used to convey the demoulded rod 100; the demoulding component 3 includes a first clamp 31, a second clamp 32, a positioning groove 33 and a support frame 34, the positioning groove 33 is arranged on one side of the discharge end of the loading platform 1, and the rod 100 to be demoulded is sequentially conveyed from the loading platform 1 to the positioning groove 33; the support frame 34 is erected above the loading platform 1, one end of the first clamp 31 is connected to the support frame 34, and the other end of the first clamp 31 is located above the positioning groove 33, and can grab and lift the rod 100 to be demoulded on the positioning groove 33; one end of the second clamp 32 is connected to the unloading platform 2, and the other end of the second clamp 32 is located on one side of the positioning groove 33, and can grab and transfer the demoulded rod 100.

[0032] The first clamp 31 in the demoulding assembly 3 lifts one end of the rod 100 to be demoulded from the positioning groove 33, so that the rod 100 to be demoulded is at a certain angle to the positioning groove 33, and the rod 100 slides out of the mold by its own gravity, and the second clamp 32 grabs one end of the rod 100 that has been ejected from the mold. The first clamp 31 and the second clamp 32 cooperate with each other to pull the rod 100 out of the mold in parallel, so that it is completely separated from the mold and the demoulding is completed; by controlling the coordinated work of the first clamp 31 and the second clamp 32, the automatic operation of the rod 100 from loading to unloading is realized. The first clamp 31 is provided with a stable support by the support frame 34, ensuring the stable grasping and lifting of the first clamp 31 during the demolding process, thus avoiding the falling or damage of the rod 100 due to unstable operation and protecting the integrity of the rod 100. Therefore, the rod demolding auxiliary device automatically completes the demolding operation, reduces the direct participation of personnel in dangerous mechanical operations, reduces potential safety risks in the demolding process, ensures the demolding quality of the rod 100, and improves the work efficiency of the production line. Among them, the support frame 34 can be but not limited to a truss, and no specific limitation is made here. If a truss is used, the characteristics of the truss being light weight and high strength can be utilized to increase the stability of the device and effectively resist loads from different directions. At the same time, the truss structure is composed of rods, with a large internal space and high space utilization, which can provide more installation space for the internal components of the device.

[0033] like Figure 1 As shown, in order to ensure that the rod 100 to be demolded is smoothly transferred from the loading platform 1 to the positioning groove 33, in some embodiments, the demolding assembly 3 also includes a guide ramp 35, which is arranged between the side of the positioning groove 33 close to the loading platform 1 and the discharge end of the loading platform 1, and the height of the guide ramp 35 gradually decreases from the loading platform 1 to the positioning groove 33; wherein the guide ramp 35 can guide the rod 100 to be demolded to slide smoothly from the loading platform 1 into the positioning groove 33, thereby avoiding the rod 100 to be demolded from deviating from the designated route, thereby causing the rod 100 to slide down and be damaged; at the same time, the guide ramp 35 is designed to be inclined, so that the rod 100 can move smoothly by relying on its own gravity, reducing the impact and collision caused by the height difference, and protecting the surface of the rod 100 from damage; in addition, through the guidance of the guide ramp 35, the rod 100 can enter the positioning groove 33 more accurately and quickly, shortening the time of the conveying process, improving the conveying speed and efficiency, and ensuring smooth connection between each process. Furthermore, the slope of the guide ramp 35 is in the range of 10° to 30°, which can ensure that the demoulding object can slide smoothly into the positioning groove 33 with less impact force.

[0034] To further protect the demolding rod 100 from damage, in some embodiments, the demolding assembly 3 further includes a buffer member disposed within the positioning groove 33. The buffer member can effectively absorb the impact force of the rod 100 entering the positioning groove 33, reducing the hard collision between the demolding rod 100 and the positioning groove 33, and preventing damage to the surface of the demolding rod 100 due to the impact. Furthermore, the buffer member can be, but is not limited to, a rubber pad or a spring pad, which is not specifically limited here.

[0035] Continue as Figure 1 As shown, to improve the versatility of the rod demolding auxiliary device, in some embodiments, the width of the positioning groove 33 gradually increases from the interior of the positioning groove 33 to its outer edge. This design allows the positioning groove 33 to accommodate rods 100 of varying diameters to be demolded, eliminating the need for frequent equipment adjustments. This increases the versatility of the device and makes it suitable for demolding rods 100 of various specifications. The cross-section of the positioning groove 33 can be, but is not limited to, a V-shape or a trapezoidal shape, which is not specifically limited herein.

[0036] In order to ensure the demolding quality of the rods 100 to be demolded in the positioning groove 33, in some embodiments, the rod demolding auxiliary device also includes a blocking component 4, which is located at the discharge end of the loading platform 1 to block the rods 100 to be demolded from being transferred to the positioning groove 33; by locating the blocking component 4 at the discharge end of the loading platform 1, the operator can effectively control the transfer rhythm of the rods 100 to be demolded. When there are still rods 100 being demolded in the positioning groove 33, the blocking component 4 can prevent new rods 100 to be demolded from entering the positioning groove 33, thereby avoiding affecting the quality and efficiency of the current demolding operation and ensuring the smooth progress of the demolding process. Specifically, the blocking component 4 includes a blocking member 41 and a lifting drive member 42. The blocking member 41 is arranged on the discharge end side of the loading platform 1, and the output end of the lifting drive member 42 is connected to the blocking member 41 to drive the lifting and lowering of the blocking member 41; the height of the blocking member 41 is flexibly and controllably adjusted by the lifting drive member 42. When blocking is required, the operator controls the lifting drive member 42 to allow the blocking member 41 to rise, thereby preventing the transmission of new rods 100 to be demolded; when blocking is not required, the operator controls the lifting drive member 42 to allow the blocking member 41 to descend, and the loading platform 1 continues to transmit new rods 100 to be demolded to the positioning groove 33; the above operations can all be completed through precise control, making the adjustment of the blocking member 41 more convenient and automated, reducing the need for manual intervention, and enabling the operator to quickly and easily adjust the blocking component 4, thereby improving work efficiency. Furthermore, in some embodiments, at least two blocking members 41 are provided, the loading platform 1 includes a roller 11 and a roller drive motor, the rollers 11 are placed side by side in sequence, the rollers 11 are configured to convey the rods 100 to be demolded, the blocking members 41 are arranged in sequence from the discharge end to the feed end of the loading platform 1, the blocking members 41 can be passed between adjacent rollers 11, and one rod 100 to be demolded is allowed to be placed between adjacent blocking members 41, and the output end of the roller drive motor is connected to the roller 11 to drive the roller 11 to rotate; by providing multiple blocking members 41 and arranging them at intervals between the rollers 11, the conveying process of the rods 100 to be demolded can be more effectively controlled, each blocking member 41 can independently block a rod 100 to be demolded, avoiding multiple rods 100 from entering the demolding area at the same time, and ensuring the order and accuracy of demolding; at the same time, it also reduces the accumulation of the rods 100 to be demolded on the loading platform 1 during the conveying process, thereby protecting the integrity of the rods 100 to be demolded.

[0037] like Figure 2As shown, in order to improve the demoulding efficiency of the rod demoulding auxiliary device, in some embodiments, the rod demoulding auxiliary device further includes a demoulding cylinder 5, which is arranged on the unloading platform 2 and is opposite to the positioning groove 33. The output end of the demoulding cylinder 5 can be extended into the mold to provide a supporting force for the rod 100; when the rod 100 to be demoulded is located in the positioning groove 33, the first clamp 31 lifts one end of the rod 100 to be demoulded, and the demoulding cylinder 5 can be extended into the mold to apply a certain supporting force to the rod 100, so that the demoulding cylinder 5 supports the rod 100, and as the cylinder gradually retracts , using the weight of the rod 100 itself, the rod 100 slides downward, and the rod 100 partially slides out of the mold. At this time, the second clamp 32 is used to grab one end of the rod 100 that has been removed from the mold. Through the cooperation of the first clamp 31 and the second clamp 32, the rod 100 is pulled out of the mold in parallel, so that it is completely separated from the mold, and the demolding is completed; wherein the supporting force of the demolding cylinder 5 can provide support and cushioning for the rod 100, preventing the rod 100 from falling from the mold. The demolding cylinder 5 can provide continuous and stable supporting force, which can ensure that the rod 100 is demolded evenly and smoothly. Furthermore, the rod demolding auxiliary device also includes a cylinder bracket, which is configured to support the demolding cylinder 5. The cylinder bracket can adjust the rotation angle of the demolding cylinder 5. The demolding cylinder 5 adjusts the angle through the bracket, so as to more flexibly apply supporting force to the angle of the rod 100 to be demolded, which is lifted by the first clamp 31.

[0038] To enhance the clamping stability of the first and second clamps 31 and 32, in some embodiments, anti-slip members are provided on the contact surfaces of the first and second clamps 31 and 32 with the rod 100. These anti-slip members increase the friction between the first and second clamps 31 and 32 and the rod 100, preventing the rod 100 from slipping or becoming loose during demolding or handling, thereby ensuring operational stability. Specifically, the anti-slip members may be, but are not limited to, rubber pads, and are not specifically limited herein.

[0039] The following is the operating process of the rod demoulding auxiliary device:

[0040] First, the bar material 100 to be demoulded is transferred from the loading platform 1 to the positioning groove 33;

[0041] Next, the first clamp 31 is used to grab one end of the bar 100 to be demolded in the positioning groove 33, and the one end of the bar 100 to be demolded is lifted so that the bar 100 to be demolded forms a certain angle with the positioning groove 33. The bar 100 is partially slid out of the mold onto the positioning groove 33 by its own weight.

[0042] Then, the second clamp 32 is used to grab one end of the rod 100 that has been released from the mold, and the first clamp 31 and the second clamp 32 cooperate to pull the rod 100 out of the mold in parallel, so that it is completely separated from the mold, and the demolding is completed;

[0043] Finally, the demoulded rod 100 is transferred to the unloading platform 2 by the second clamp 32 for the next step, and the first clamp 31 transfers the demoulded mold out of the positioning groove 33 .

[0044] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
