Description

Technical Field

[0001] This invention relates to the field of piezoelectric jacquards, and in particular to a piezoelectric jacquard with a drive circuit board. Background Technology

[0002] Currently, wireless piezoelectric jacquards all employ a dual power supply system with independent high-voltage DC and low-voltage DC power supplies. The high-voltage DC power supply is dedicated to powering the piezoelectric ceramic drive circuit to meet the high-voltage drive conditions required for the inverse piezoelectric effect of the piezoelectric ceramic; the low-voltage DC power supply powers the jacquard's internal main control circuit, signal processing circuit, and peripheral auxiliary circuits, and generates multiple low-voltage operating voltages through an internal voltage conversion module to ensure the normal operation of the control system.

[0003] This traditional dual-power supply mode has inherent defects in practical applications: the two power supplies are distributed separately, and multiple power supply interfaces need to be configured on the Jacquard body and the drive end, which not only makes the structural layout redundant and complicated. Summary of the Invention

[0004] The present invention provides a piezoelectric Jacquard with a driving circuit board to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: A piezoelectric jacquard with a driving circuit board has the following features: The yarn guide pin block, wherein the yarn guide pins of the yarn guide pin block are made of stainless steel; A driving circuit board, mounted on the rear of the yarn guide needle block, is used to drive the piezoelectric ceramic sheet of the yarn guide needle block to deform; and The transformer is integrated within the drive circuit board. A first AC current is input from the input terminal of the drive circuit board, and the first AC current is transmitted to the input terminal of the transformer. A second AC current is output from the output terminal of the transformer. The transformer is used to convert the first voltage of the first AC current into the second voltage of the second AC current.

[0006] In one possible implementation, the transformer has a magnetic core and a primary winding and a secondary winding wound on the magnetic core. The two ends of the primary winding are connected to the input terminal of the transformer through a fourth conductive line layer on the drive circuit board to form a primary-side input circuit for transmitting a first voltage of a first alternating current. The two ends of the secondary winding are connected to the output terminal of the transformer through a fourth conductive line layer on the drive circuit board to form a secondary-side output circuit for outputting a second voltage of a second alternating current. The primary winding and the secondary winding satisfy the voltage-turns correspondence U1 / U2=N1 / N2, where N1 is the number of turns in the primary winding and N2 is the number of turns in the secondary winding, and the number of turns N2 in the secondary winding is greater than the number of turns N1 in the primary winding, so as to realize the conversion from the first voltage of the input first alternating current to the second voltage of the output second alternating current.

[0007] In one possible implementation, the output terminal of the transformer is electrically connected to a first rectifier circuit, which converts the second alternating current into a first direct current, the voltage of which is 160V to 200V. The output terminal of the first rectifier circuit is electrically connected to a piezoelectric ceramic drive circuit.

[0008] In one possible implementation, the first rectifier circuit is either a full-wave rectifier circuit or a half-wave rectifier circuit.

[0009] In one possible implementation, both the first rectifier circuit and the piezoelectric ceramic drive circuit are integrated within the drive circuit board.

[0010] In one possible implementation, the ratio of the number of turns in the primary winding to the number of turns in the secondary winding is 1:X, where X ranges from 2 to 10.

[0011] In one possible implementation, the second voltage ranges from 160V to 200V.

[0012] In one possible implementation, the first voltage ranges from 10V to 100V.

[0013] In one possible implementation, a first interface is provided on the left side of the drive circuit board. The first interface is used to transmit a first alternating current, and the output end of the first interface is electrically connected to the input end of the transformer.

[0014] In one possible implementation, a second interface is provided on the right side of the driver circuit board. The second interface is used to transmit the first AC power, and the output terminal of the first interface is electrically connected to the input terminal of the second interface.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention features a simple structure and strong practicality. The transformer is directly integrated into the drive circuit board, which is assembled at the rear of the yarn guide needle block. The structure is highly integrated and compactly arranged. The first AC power is introduced through the input terminal of the drive circuit board, and the transformer realizes the voltage adaptation conversion from the first voltage to the second voltage. The power transmission path is short and the line loss is small, which effectively reduces the electromagnetic interference and poor contact risk caused by external lines. It improves the stability and reliability of piezoelectric Jacquard power transmission and can provide a stable and compatible AC input power for the subsequent piezoelectric ceramic sheet deformation drive, ensuring the smooth and reliable operation of the yarn guide needle block needle selection action.
