Description

Technical Field

[0001] This utility model relates to the field of rotating target forming technology, specifically to a rotating target loading and compaction device. Background Technology

[0002] In the processing of rotary sputtering targets, the molding powder is typically introduced into a mold, and then compacted. This is because, in its naturally filled state, the powder particles have many gaps and a low packing density. Through compaction, the powder particles move, collide, and rearrange within the mold, reducing the gaps and creating a denser packing, thus increasing the packing density. This contributes to better compactness and mechanical properties in subsequent molding processes. Furthermore, during compaction, the powder flows and diffuses within the mold under vibration, effectively improving its distribution and ensuring even filling of all corners and complex shapes. Moreover, the friction and collisions between the powder particles during compaction increase the contact area and friction, strengthening the bond between them and ultimately improving the strength and toughness of the rotary sputtering target.

[0003] Traditional vibration compaction devices mainly consist of a movable base, a support spring located below the movable base, and a vibrator. The mold is placed on the movable base, and the vibration is transmitted to the mold through the vibrator and spring, causing the mold to vibrate to achieve a compaction effect. However, this method weakens the vibration intensity when the upper forming mold is heavy, resulting in a poorer compaction effect. Furthermore, because the vibration energy gradually decreases from bottom to top, the compaction effect at the top of the mold is prone to be poor, ultimately leading to instability in the size and density of the formed rotating target blank. Utility Model Content

[0004] The purpose of this utility model is to provide a rotating target material loading and compaction device to solve the technical problem of the quality of the formed rotating target material that is prone to occur during the use of existing compaction devices.

[0005] To solve the above problems, the present invention provides a rotating target material loading and compaction device with the following technical solution:

[0006] A rotating target material loading and compaction device includes: a fixed base, a rotating seat, adjusting vertical rods, and a pneumatic vibration hammer; the rotating seat is rotatably mounted on the fixed base, and the rotating seat has an opening for the rotating target mold to pass through; at least two adjusting vertical rods are provided and are respectively arranged on both radial sides of the rotating seat, and the adjusting vertical rods are rotatably mounted to the rotating seat.

[0007] At least two pneumatic hammers are provided and arranged on the radial sides of the rotating base respectively. The pneumatic hammers are mounted on the adjusting vertical rods on the corresponding sides in a vertical direction so as to strike the rotating target mold in the circumferential and vertical directions.

[0008] The beneficial effects of this utility model are as follows: This utility model enables the pneumatic vibratory hammer to rotate circumferentially through the rotating base. During the circumferential rotation, the pneumatic vibratory hammer can vibrate and hammer the rotating target mold from different circumferential directions. Furthermore, the pneumatic vibratory hammer can rise and fall, thereby vibrating and hammering the rotating target mold from different heights, ensuring that the rotating target mold can be evenly struck in both the circumferential and vertical directions. Compared with existing compaction devices, this utility model can achieve a more uniform and dense compaction effect for the powder particles inside the rotating target mold.

[0009] Furthermore, a drive assembly for driving the rotating seat to rotate is provided between the fixed base and the rotating seat, the adjusting vertical rod is an adjusting screw, a transmission assembly for driving the adjusting vertical rod to rotate is provided between the rotating seat and the corresponding adjusting vertical rod, and a sliding sleeve that is threadedly engaged with the adjusting vertical rod is fixed on the pneumatic vibrating hammer.

[0010] Beneficial effects: It can realize the automatic lifting and lowering of the pneumatic vibratory hammer and the automatic rotation of the rotating seat without human intervention, with a high degree of automation.

[0011] Furthermore, the transmission assembly includes an outer adjusting gear ring and an inner adjusting gear ring arranged coaxially with the rotating seat and radially spaced apart from the rotating seat. A transmission gear located above the rotating seat is coaxially fixed on the adjusting vertical rod. Both the outer adjusting gear ring and the inner adjusting gear ring are fixed to the rotating seat and can move up and down relative to the rotating seat. The outer adjusting gear ring and the inner adjusting gear ring are respectively provided with outer teeth and inner teeth that can mesh and disengage with the transmission gear. A switching mechanism is provided on the fixed base, which is used to switch the outer adjusting gear ring and the inner adjusting gear ring to mesh or disengage with the transmission gear.

[0012] Beneficial effects: The pneumatic hammer can move upward and downward respectively through the internal and external adjusting gear rings. The structure is simple and easy to install.

[0013] Furthermore, the switching mechanism includes a handle, an adjusting head, and a lever. The adjusting head is rotatably mounted in the fixed base via a first rotating shaft, and the lever is rotatably mounted in the fixed base via a second rotating shaft. The axes of the first and second rotating shafts are parallel and both perpendicular to the axis of the rotating seat. The handle is located outside the fixed base and connected to the first rotating shaft to drive the adjusting head to rotate. The lever has an arc-shaped contact surface, and the adjusting head has an arc-shaped top surface that contacts the arc-shaped contact surface. The curvature of the arc-shaped top surface is greater than the curvature of the arc-shaped contact surface. The two ends of the lever are respectively hinged to an inner adjusting gear ring and an outer adjusting gear ring. A locking mechanism is also provided between the fixed base and the handle.

[0014] Beneficial effects: The switching mechanism uses levers to achieve the alternating up and down movement of the inner and outer adjusting gear rings, which is simple in structure and occupies little space; the locking mechanism can ensure that the inner and outer adjusting gear rings are stably engaged with the transmission gear at the same height, thereby ensuring the stability of the pneumatic vibrating hammer during lifting and lowering.

Both the outer slider and the inner slider are fixed to the fixed base by pins.

[0016] Beneficial effects: Makes the internal and external adjusting gear rings more stable when moving up or down, preventing deviation.

[0017] Furthermore, the locking mechanism includes a first locking hole and a second locking hole on the fixed base, an insertion hole on the handle, and a locking pin. When the locking pin is inserted into the insertion hole and the first locking hole, the outer adjusting gear ring is engaged with the transmission gear. When the locking pin is inserted into the insertion hole and the second locking hole, the inner adjusting gear ring is engaged with the transmission gear.

[0018] Beneficial effects: The locking mechanism, which uses a pin to connect to the corresponding lock hole, is simpler in structure; in addition, the arrangement of the first and second lock holes also has a certain positioning function. When the operator turns the handle to the position of the first or second lock hole, he can determine that the outer or inner adjusting gear ring is engaged with the transmission gear.

[0019] Furthermore, two adjusting vertical rods are diagonally distributed on the rotating base, and two sliding rods are also fixedly connected to the rotating base. The two sliding rods and the two adjusting vertical rods form a rectangle. Each adjacent adjusting vertical rod and sliding rod is connected to a supporting horizontal rod. The two ends of the supporting horizontal rods are respectively provided with the sliding sleeves. The ends of two adjacent supporting horizontal rods that are close to each other are connected to the same sliding sleeve. The pneumatic vibration hammer is fixed between the adjacent adjusting vertical rods and sliding rods by a bracket.

[0020] Beneficial effects: Ensures the stability of the pneumatic hammer during the lifting process; in addition, it can reduce the number of sliding sleeves used.

[0021] Furthermore, two pneumatic shock hammers arranged vertically at intervals are connected to the same support.

[0022] Beneficial effects: The use of two pneumatic impact hammers arranged at intervals can cover a wider area, allowing all parts of the rotating target mold to be impacted; in addition, it can also make the rotating target mold bear force evenly in the vertical direction, reduce the deformation of the rotating target mold, and extend the service life of the rotating target mold.

[0035] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Those skilled in the art should understand that the embodiments described below are only some, not all, of the embodiments disclosed. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0036] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0037] Example 1 of the rotating target material loading and compaction device provided by this utility model:

[0038] like Figure 1 and Figure 2 As shown, the rotating target loading and compaction device includes: a fixed base 1, a rotating seat 2 rotatably mounted on the fixed base 1, an adjusting vertical rod 3 rotatably mounted on the rotating seat 2, a liftable pneumatic vibrating hammer 4, a drive assembly for driving the rotating seat 2 to rotate, and a transmission assembly for realizing the rotation of the adjusting vertical rod 3.

[0039] Specifically, the rotating seat 2 is an annular seat located above the fixed base 1. The center of the rotating seat 2 has an opening through which the rotating target mold 26 can pass, and the rotating target mold 26 can pass through the opening and be placed on the fixed base 1.

[0040] like Figure 1 As shown, the fixed base 1 has a support 27 on its side. The driving assembly includes a motor 9 fixed on the support 27, a drive pulley connected to the motor 9, and a transmission belt 10 wound between the drive pulley and the rotating base 2. The diameter of the drive pulley is much smaller than the outer diameter of the rotating base 2. When the motor 9 rotates, the drive pulley rotates, which in turn drives the rotating base 2 to rotate via the transmission belt 10. Of course, in other embodiments, a sprocket and chain can also be used to move the rotating base 2.

[0041] like Figure 3 and Figure 5 As shown, two adjusting vertical rods 3 are rotatably mounted on the rotating base 2 via bearings 25, and two sliding rods 5 are fixedly connected to the rotating base 2. The adjusting vertical rods 3 are threaded rods, and the sliding rods 5 are smooth rods. The two adjusting vertical rods 3 are diagonally distributed on the rotating base 2, located on both radial sides of the rotating base 2; the two sliding rods 5 are also diagonally distributed on the rotating base 2, forming a rectangle with the two adjusting vertical rods 3. Each adjacent adjusting vertical rod 3 and sliding rod 5 is connected to a supporting horizontal rod 14, meaning there are four supporting horizontal rods 14 in total. Each end of a supporting horizontal rod 14 is connected to a sliding sleeve 11, and the ends of two adjacent supporting horizontal rods 14 that are close to each other are connected to the same sliding sleeve 11. Of the four sliding sleeves 11, two diagonally arranged sliding sleeves 11 are threadedly connected to the adjusting vertical rods 3, while the other two diagonally arranged sliding sleeves 11 are slidably engaged with the sliding rods 5.

[0042] A bracket 13 is connected between each of the two supporting crossbars 14 connected to the sliding sleeve 11 on each adjusting vertical rod 3, and the two brackets 13 are also arranged diagonally. Each bracket 13 is connected to two pneumatic vibration hammers 4 arranged vertically at intervals. The pneumatic vibration hammer 4 is a device that uses compressed air as power to generate impact force through the reciprocating motion of a piston, thereby achieving the effect of impacting objects. The pneumatic vibration hammer 4 is existing technology, and its specific structure will not be described in detail here.

[0043] like Figure 4As shown, the rotating base 2 has an annular groove 6. The transmission assembly includes an outer adjusting gear ring 7 and an inner adjusting gear ring 8, which are coaxial with the rotating base 2 and installed in the annular groove 6. The outer adjusting gear ring 7 and the inner adjusting gear ring 8 are arranged radially spaced apart on the rotating base 2. The rotating base 2 has an outer limiting groove and an inner limiting groove communicating with the annular groove 6 on its radial sides, respectively. The outer adjusting gear ring 7 has an outer slider 23 that slides in a vertical direction with the outer limiting groove, and the inner adjusting gear ring 8 has an inner slider 24 that slides in a vertical direction with the inner limiting groove. Both the outer slider 23 and the inner slider 24 are fixed to the fixed base 1 by pins 30. At this time, the inner adjusting gear ring 8 and the outer adjusting gear ring 7 can move vertically relative to the pins 30. The outer adjusting gear ring 7 has an outer ring of teeth on its inner side, and the inner adjusting gear ring 8 has an inner ring of teeth on its outer side. A transmission gear 12 is coaxially connected to the adjusting vertical rod 3. The transmission gear 12 is located above the rotating seat 2. When the outer adjusting gear ring 7 and the inner adjusting gear ring 8 move upward to the set position, the outer and inner teeth can mesh with the transmission gear 12. When the outer adjusting gear ring 7 and the inner adjusting gear ring 8 are located in the annular groove 6, the outer and inner teeth separate from the transmission gear 12.

[0044] A switching mechanism is provided on the fixed base 1. This mechanism drives the outer adjusting gear ring 7 and the inner adjusting gear ring 8 to move upwards or downwards, thereby engaging or disengaging the outer adjusting gear ring 7 and the inner adjusting gear ring 8 with the transmission gear 12. In this embodiment, as... Figure 5 As shown, the switching mechanism includes a handle 17, an adjusting head 15, and a lever 16. The adjusting head 15 is rotatably mounted in the fixed base 1 via a first rotating shaft, and the lever 16 is rotatably mounted in the fixed base 1 via a second rotating shaft. The axes of the first and second rotating shafts are parallel and both perpendicular to the axis of the rotating seat 2. The handle 17 is located outside the fixed base 1 and connected to the first rotating shaft. When the handle 17 is rotated, the adjusting head 15 can rotate. The lever 16 has an arc-shaped contact surface 18, and the adjusting head 15 has an arc-shaped top surface 19 that contacts the arc-shaped contact surface 18. The curvature of the arc-shaped top surface 19 is greater than the curvature of the arc-shaped contact surface 18. The bottom of both the outer adjusting gear ring 7 and the inner adjusting gear ring 8 has a connecting part with a triangular cross-section. The two ends of the lever 16 are hinged to the connecting parts of the inner adjusting gear ring 8 and the outer adjusting gear ring 7, respectively.

[0045] A locking mechanism is also provided between the fixed base 1 and the handle 17. In this embodiment, as shown... Figure 1 As shown, the locking mechanism includes a first locking hole 20 and a second locking hole 21 on the fixed base 1, an insertion hole 22 on the handle 17, and a locking pin. When the handle 17 is rotated clockwise and the locking pin is inserted into the insertion hole 22 and the first locking hole 20, the outer adjusting gear ring 7 is engaged with the transmission gear 12. When the handle 17 is rotated counterclockwise and the locking pin is inserted into the insertion hole 22 and the second locking hole 21, the inner adjusting gear ring 8 is engaged with the transmission gear 12.

[0046] A support rod 29 is fixed on the side of one of the adjusting vertical rods 3 on the fixed base 1. The support rod 29 is provided with shock hammer limiters 28 arranged at intervals to limit the upward and downward movement of the pneumatic shock hammer 4.

[0047] The working process of the rotating target material loading and compaction device of this utility model is as follows: The rotating target mold 26 is placed into the opening of the rotating seat 2 and supported on the fixed base 1. The handle 17 is turned clockwise. At this time, the adjusting top head 15 rotates clockwise, the left end of the lever 16 is raised and the right end is lowered. At this time, the left end of the lever 16 pushes the outer adjusting gear ring 7 upward, so that its outer teeth mesh with the transmission gear 12. The locking pin is inserted into the insertion hole 22 and the first locking hole 20, so that the outer adjusting gear ring 7 is kept in the current position. The motor 9 and the pneumatic vibration hammer 4 are turned on. At this time, the pneumatic vibration hammer 4 moves downward under the action of the adjusting vertical rod 3 and rotates with the rotating seat 2, thereby vibrating and hammering the rotating target mold 26 in the circumferential and vertical directions, so that the powder particles inside the rotating target mold 26 obtain a more uniform and dense compaction effect. When the pneumatic hammer 4 needs to move upward, pull out the locking pin and turn the handle 17 counterclockwise. At this time, the left end of the lever 16 descends and the right end rises. The right end of the lever 16 pushes the inner adjusting gear ring 8 upward, so that its inner teeth mesh with the transmission gear 12. Insert the locking pin into the insertion hole 22 and the second locking hole 21 to keep the inner adjusting gear ring 8 in the current position. At this time, turn on the motor 9 to realize the upward movement of the pneumatic hammer 4.

[0048] Embodiment 2 of the rotating target material loading and compaction device provided by this utility model:

[0049] Its main difference from Example 1 is:

[0050] In Example 1, the switching mechanism adopts the form of adjustment head and lever cooperation.

[0051] In this embodiment, the switching mechanism can also employ two L-shaped pull rods connected to an outer adjusting gear ring and an inner adjusting gear ring respectively. The vertical section of the L-shaped pull rod is used to connect with either the outer or inner adjusting gear ring, while the horizontal section of the L-shaped pull rod slides vertically with the fixed base. The fixed base has a groove that engages with the horizontal section of the L-shaped pull rod. Two limiting blocks are positioned on the left and right sides of the top of the groove, each with a recessed groove. When the horizontal section of the L-shaped pull rod is at the bottom of the groove, the outer or inner adjusting gear ring is located in the annular groove of the rotating seat, separated from the transmission gear. When the horizontal section of the L-shaped pull rod is at the top of the groove, the outer or inner adjusting gear ring meshes with the transmission gear. Placing a stop bar in the recesses of the two limiting blocks prevents the L-shaped pull rod from moving downwards, thus locking the outer or inner adjusting gear ring.

[0052] Embodiment 3 of the rotating target material loading and compaction device provided by this utility model:

[0053] Its main difference from Example 1 is:

[0054] In Example 1, each support is equipped with two pneumatic vibration hammers arranged at intervals.

[0055] In this embodiment, only one pneumatic vibrating hammer is installed on each support. Of course, it is not limited to one or two pneumatic vibrating hammers on each support; multiple hammers can also be installed.

[0056] Based on the above description in this specification, those skilled in the art will also understand that terms used, such as "upper," "lower," "left," "right," "top," "bottom," "inner," and "outer," which indicate orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings of this specification. They are only for the purpose of facilitating the explanation of the present invention and simplifying the description, and do not imply that the device or element involved must have the specific orientation, or be constructed and operated in a specific orientation. Therefore, the above-mentioned orientation or positional relationship terms should not be understood or interpreted as limitations on the present invention.

[0057] In addition, in the description of this specification, "multiple" means at least two, such as two, three or more, etc., unless otherwise expressly and specifically defined.

[0058] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
