Description

Technical Field

[0001] This utility model relates to vibratory feeders, and more particularly to a levelable piezoelectric vibratory feeder. Background Technology

[0002] A vibratory feeder is an auxiliary feeding device for automatic assembly or processing machinery, also known as a parts feeding device. The working principle of a vibratory feeder involves a frequency converter and motor to achieve automatic conveying. A pulse electromagnet under the hopper causes the hopper to vibrate vertically. An inclined spring plate drives the hopper to oscillate around its vertical axis. Parts inside the hopper rise along a spiral track due to this vibration. During this ascent, they undergo a series of track selections or posture changes, allowing them to automatically enter the assembly or processing position in a uniform state according to assembly or processing requirements. Its purpose is to automatically and orderly arrange disordered workpieces through vibration, accurately conveying them to the next process.

[0003] Piezoelectric vibratory feeders are a new type of vibratory feeding equipment that uses piezoelectric ceramics as the driving source. They use the inverse piezoelectric effect of the piezoelectric sheet to generate vibration, which drives the material trough to achieve material transfer. However, the driving force of piezoelectric vibratory feeders is slightly insufficient and cannot transport excessively heavy materials. Therefore, these devices are mostly used for micro or precision material transfer. Existing piezoelectric vibratory feeders are prone to material transfer deviation and misalignment due to unevenness of the vibration platform, which can lead to the inability to complete the material transfer normally.

[0004] Authorization announcement number CN215363322U discloses a height-adjustable vibratory feeder base, specifically comprising: a base with symmetrically fixed leveling components at the bottom and a hollow cylindrical sleeve fixed at the top. The inner cavity of the hollow cylindrical sleeve is connected to a lifting column via a lifting mechanism, which controls the lifting of the lifting column to adjust the height of the vibratory feeder. However, this prior art only achieves overall height adjustment of the vibratory feeder and cannot achieve leveling of the vibratory feeder itself.

[0005] In summary, designing a vibratory feeder that can be leveled is a technical problem that needs to be solved. Utility Model Content

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of the present utility model. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present utility model.

[0030] This invention provides an adjustable piezoelectric vibratory feeder, including a drive assembly, multiple detection assemblies, and a vibration platform 13.

[0031] The drive assembly includes a drive source 11 and multiple drive units. The drive source 11 includes a support housing 12, which is integrally formed. A vibration platform 13 is mounted on one end of the drive source 11, and the support housing 12 at the other end has a mounting groove for mounting the drive units. Multiple drive units are equidistantly mounted on the support housing 12. Each drive unit includes an electric push rod 19, a compression shell 14, and a shock-absorbing pad 18. The electric push rod 19 is installed in the mounting groove, passes through the support housing 12, and is slidably connected to the drive unit. One end of the compression shell 14 is connected to the output end of the electric push rod 19, and the other end has a shock-absorbing pad 18 fixed inside, which contacts the ground.

[0032] Multiple detection components are equidistantly mounted around the drive source 11 and the vibration platform 13. The number of detection components is the same as that of the drive unit, and their installation orientation is the same. Each detection component includes a laser 16 and a laser receiver 17. The axes of the laser 16 and the laser receiver 17 are coincident, and the laser emitted by the laser 16 can be received by the laser receiver 17. The laser 16 is mounted around the drive source 11, and the laser receiver 17 is mounted around the vibration platform 13.

[0033] The laser 16 is equipped with a protective sleeve 15. The end of the protective sleeve 15 near the laser 16 that emits the laser is provided with protective glass to ensure that the laser is emitted normally while preventing the laser 16 from accumulating dust or being worn. The laser receiver head 17 is installed around the vibration platform 13 through a mounting base to adapt to vibration platforms 13 of different shapes.

[0034] The vibration platform 13 is mounted on top of the drive source 11, which generates vibration using the inverse piezoelectric effect of the piezoelectric element. Laser receiver heads 17 are equidistantly mounted on the sides of the vibration platform 13.

[0035] To facilitate automatic leveling, this invention can also be equipped with a processor, which is electrically connected to the drive unit, detection components, and vibration platform 13. The processor executes a pre-written program, causing the electric push rod 19 to automatically travel a specified distance to complete fully automatic leveling.

[0036] The working principle of this utility model is as follows:

[0037] The vibration of the vibration platform 13 is measured at high speed by using laser 16 in conjunction with laser receiver 17. After assembling the drive source 11 and the vibration platform 13, the balance is monitored by measuring the amplitude of each point on the vibration platform 13. If the amplitude difference is too large, the vibration platform 13 is in an unbalanced state, which will affect the material conveying. In this state, the electric push rod 19 is activated to push the extrusion shell 14 to move, which drives the shock-absorbing foot pad 18 to move, adjusting the support height of the drive source 11 and the vibration platform 13, so that the vibration platform 13 is kept balanced without the need for manual leveling and testing.

[0038] The automatic leveling function of this utility model is not limited to shape, appearance, or size; it can be a square, round, or irregularly shaped vibratory plate.

[0039] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in this utility model, and these modifications or substitutions should all be covered within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
