Technical Field
[0001] This utility model relates to the field of oscillator technology, and in particular to vortex oscillators. Background Technology
[0002] Vortex oscillators are primarily used in research fields such as medicine, bioengineering, chemistry, and pharmaceuticals. They are essential instruments in biological laboratories for fixing, oscillating, and mixing various reagents, solutions, and chemical substances. Currently, most commercially available vortex oscillators, including the oscillation table and base, use a motor to drive an eccentric wheel, causing the oscillation table to oscillate relative to the base. After power failure, the oscillation table cannot quickly return to its initial position relative to the base, and the position after each reset is not precise enough, easily leading to errors. This causes inconvenience for subsequent automated handling mechanisms such as robotic arms. Current methods for restoring the oscillation table to its original position after power failure mainly rely on the principle of the object's own deformation recovery; however, there is no effective control method for the rapid and accurate restoration of the oscillation table to its original position.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0026] It should be noted that when a component is referred to as "fixed to" or "set on" another component, it can be directly on the other component or may have an intervening component present. When a component is referred to as "connected to" another component, it can be directly connected to the other component or may have an intervening component present.
[0027] like Figures 1 to 7 As shown, this utility model provides a vortex oscillator, including: a base 1 and an oscillation table 2 disposed above the base 1. A motor oscillation part is disposed below the central region of the oscillation table 2. The motor oscillation part includes a motor 3 connected to the oscillation table 2 and an eccentric wheel 4 connected to the output shaft of the motor 3 at the end away from the oscillation table 2. A support structure and a limiting structure are disposed between the base 1 and the oscillation table 2. Mutually exclusive structures are disposed at multiple symmetrical positions around the base 1 and the oscillation table 2 to allow the oscillation table 2 to reset.
[0028] Specifically, by setting mutually exclusive structures at multiple symmetrical positions around the base 1 and the oscillating table 2, a mutual repulsive force is generated between the base 1 and the oscillating table 2. For the mutually exclusive structures at the symmetrical positions, as the relative position between the oscillating table 2 and the base 1 increases on one side, it decreases on the other side. This results in a smaller mutual repulsive force on one side and a larger mutual repulsive force on the opposite side. When the oscillator stops working and has not returned to its original position, due to the difference in the magnitude of the mutual repulsive forces at the relative positions, the unequal mutual repulsive forces at the symmetrical positions interact to restore the oscillating table 2 and the base 1 to their original positions to achieve equilibrium. At this time, the mutual repulsive forces at each set of symmetrical positions cancel each other out. Compared with existing oscillators that rely solely on elastic supports for reset, this method ensures that the reset position is consistent, precise, and rapid each time, which is more conducive to the loading and unloading of automated loading and unloading devices.
[0029] As an optional implementation, the motor oscillation section further includes a motor fixing plate 5 and multiple fixing pillars 6 with one end fixed to the periphery of the motor fixing plate 5. The other end of the fixing pillars 6 is connected to the bottom of the oscillation table 2. The end of the motor 3 located at one end of the output shaft is fixedly connected to the middle of the motor fixing plate 5. The output shaft of the motor 3 passes through the motor fixing plate 5, and the output end of the output shaft is fixed to the eccentric wheel 4.
[0030] Specifically, the motor mounting plate 5 is connected to the bottom of the vibration table 2 by fixing pillars 6 set around the motor mounting plate 5, the motor 3 is fixed on the motor mounting plate 5, and an eccentric wheel 4 is fixed at the output end of the motor 3 away from the vibration table 2 to provide vibration drive for the vibration table 2.
[0031] As an optional implementation, a through hole is provided in the middle of the base 1, and multiple fixed support columns 6 pass through the base 1 and are connected to the vibration table 2.
[0032] Specifically, the vibration table 2 is supported above the base 1, and the fixed support column 6 is connected to the vibration table 2 through the middle hole of the base 1, making the structure of the whole device compact.
[0033] As an optional implementation, the support structure supports the oscillation table 2 on the base 1 and keeps the oscillation table 2 in a non-contact state with the base 1.
[0034] Specifically, such as Figure 7 As shown, there are mounting holes at corresponding positions between the base 1 and the oscillating table 2. The support structure is a support rod 11, which is set in the mounting holes of the base 1 and the oscillating table 2 to support the oscillating table 2 on the base 1. In order for the oscillating table 2 to oscillate, the support rod 11 keeps the oscillating table 2 and the base 1 in a non-contact state.
[0035] As an optional implementation, the limiting structure includes a horizontal limiting structure that limits the displacement range of the oscillating table 2 relative to the base 1 in the horizontal direction. The horizontal limiting structure is a limiting ring 14 disposed on the base 1 and a limiting hole disposed on the oscillating table 2 corresponding to the limiting ring 14; or the horizontal limiting structure is a limiting ring 14 disposed on the oscillating table 2 and a limiting hole disposed on the base 1 corresponding to the limiting ring 14.
[0036] Specifically, such as Figure 7 As shown, a limiting ring 14 is mounted on a limiting ring support 13, which is fixed to the base 1 by a cylindrical pin 12. A limiting hole is correspondingly provided on the bottom of the oscillating table 2, and the limiting ring 14 is placed in the limiting hole. The diameter of the limiting hole is larger than the diameter of the limiting ring 14, so that the oscillating table 2 can move horizontally relative to the base 1. The diameter of the limiting hole at the bottom of the oscillating table 2 can be designed according to the actual oscillation amplitude requirements to determine the amplitude of the horizontal movement of the oscillating table 2 relative to the base 1. Four sets of limiting ring supports 13 and limiting rings 14 are installed on the base 1, symmetrically arranged on both sides of the through hole in the middle of the base. Alternatively, the limiting ring structure can also involve mounting the limiting ring support 13 and the limiting ring 14 on the oscillating table 2, with corresponding limiting holes on the base 1, to limit the horizontal displacement range of the oscillating table 2 relative to the base 1.
[0037] As an optional implementation, the limiting structure includes an upper and lower limiting structure, which includes a limiting screw 9 that passes through the base 1 and is fixed on the vibration table 2. The end of the limiting screw 9 has a set distance from the base 1 to limit the displacement range of the vibration table 2 relative to the base 1 in the vertical direction.
[0038] Specifically, such as Figure 5As shown, the upper limit screw 9 fixed to the vibration table 2 passes through the hole on the base 1, limiting the upward movement distance of the vibration table 2.
[0039] As an optional implementation, the mutual repulsion structure is a pair of magnets with the same poles facing each other, respectively disposed at opposite positions on the base 1 and the oscillating table 2; or the mutual repulsion structure is a ball-head plunger disposed between the base 1 and the oscillating table 2; or the mutual repulsion structure is a compression spring disposed between the base 1 and the oscillating table 2.
[0040] Specifically, such as Figure 2 , Figure 5 The structure shown is a magnet structure to provide a repulsive force acting on the oscillating table 2 and the base support, so that the oscillating table 2 returns to its initial position. In order to provide a linearly varying repulsive force between the base 1 and the oscillating table 2, the repulsive structure can be, but is not limited to, a structure of ball plunger and compression spring.
[0041] As an optional implementation, the mutual repulsion structure consists of magnets with the same poles facing each other, respectively disposed at opposite positions on the base 1 and the oscillating table 2, including: a first repulsive magnet 7 fixed to the side of the base 1 and a second repulsive magnet 15 fixed to the side of the oscillating table 2 opposite to the first repulsive magnet 7, wherein the first repulsive magnet 7 is disposed on the side near the center of the oscillator opposite to the second repulsive magnet 15.
[0042] Specifically, such as Figure 2 , Figure 5 As shown, the first repulsive magnet 7 is fixed on the magnet fixing base 8, which is fixed to the four sides of the base 1. The second repulsive magnet 15 is fixed on the magnet fixing base 16, which is fixed to the corresponding position on the four sides of the vibration table 2.
[0043] As an optional implementation, the first repulsive magnet 7 is higher than the second repulsive magnet 15 by a set height in the height direction, so that the first repulsive magnet 7 applies a downward force to the second repulsive magnet 15.
[0044] Specifically, such as Figure 5 As shown, the first repulsive magnet 7 and the second repulsive magnet 15 are aligned horizontally, with the first repulsive magnet 7 slightly higher than the second repulsive magnet 15 in the height direction. This means the second repulsive magnet 15 experiences a downward repulsive force from the first repulsive magnet 7. With this arrangement, the edges of the oscillating table 2 will undulate during oscillation. This arrangement of the first repulsive magnet 7 and the second repulsive magnet 15 ensures that the oscillating table 2 experiences a downward repulsive force, reducing the range of edge fluctuation.
[0045] As an optional implementation, a fixing plate compression spring 10 is provided between the motor fixing plate 5 and the base 1, and the fixing plate compression spring 10 has a set compression amount when assembled.
[0046] Specifically, such as Figure 6 As shown, the motor mounting plate 5 is located below the base 1. A mounting plate compression spring 10 is installed between the motor mounting plate 5 and the base 1. The number of mounting plate compression springs 10 can be two, three, four, etc. The two ends of the mounting plate compression spring 10 abut against the base 1 and the motor mounting plate 5, respectively. In one embodiment, fixing screws are installed on the base 1 and the motor mounting plate 5, and the two ends of the mounting plate compression spring 10 are respectively sleeved on the outside of the fixing screws, thus preventing the mounting plate compression spring 10 from falling off during operation. The mounting plate compression spring 10 has a certain amount of compression after installation. This provides a downward force to the vibration table 2, maintaining the stability of the vibration table 2 and reducing the upward floating amount of the vibration table 2 during operation.
[0047] Optionally, both the base 1 and the vibration table 2 are rectangular structures; four "L"-shaped block corner protectors 17 are installed on the top of the vibration table 2, and the block corner protectors 17 are respectively set at the rectangular right-angled sides of the vibration table 2. Each of the four "L"-shaped block corner protectors 17 on the vibration table 2 has a buckle 18 on its inner side.
[0048] The technical solution of this application sets symmetrical mutually exclusive structures around the oscillation table and the base, so that the oscillation table can return to its original position under the action of mutual repulsion forces around it. This avoids the limitation of the vibration amplitude by physical deformation and reset. Thus, the vibration intensity, magnitude and load can be set as needed, thereby improving the accuracy and practicality of the instrument.
