Description

Technical Field

[0001] The invention relates to a transformer, and in particular to the calibration of transformer pins. Background Art

[0002] Small transformers are used in electronic products such as televisions and monitors. They have two rows of pins. During production or transportation, the pins may be bent by external forces. Before leaving the factory, workers need to calibrate the pins. Summary of the invention

[0003] The technical problem solved by the present invention is to provide a mechanism capable of correcting the pins of a small transformer.

[0004] In order to solve the above technical problems, the present invention provides the following technical solutions: a transformer pin correction mechanism, comprising an upper correction plate and a lower correction plate, the upper correction plate is provided with a pin upper correction hole, the lower correction plate is provided with a pin lower correction hole, the pin upper correction hole and the pin lower correction hole are arranged correspondingly up and down, the bottom of the upper correction plate is provided with a square groove, the top of the lower correction plate is provided with a square convex portion, and the square groove cooperates with the square convex portion;

[0005] The upper correction plate is provided with an upper correction plate limiting structure around it, and the lower correction plate is matched in a cross-shaped bracket structure, and the cross-shaped bracket structure is connected to the vibration unit. Under the drive of the vibration unit, the cross-shaped bracket structure can vibrate forward and backward and left and right;

[0006] There is a gap between the upper correction plate limiting structure and the upper correction plate, and a gap between the square protrusion and the square groove. The lower correction plate that vibrates with the cross-shaped bracket structure can drive the upper correction plate to vibrate back and forth and left and right through the square protrusion; during the vibration process, the upper correction hole of the pin and the lower correction hole of the pin foot are misaligned back and forth and left and right, but the straight pin can be inserted into the misaligned upper correction hole of the pin and the lower correction hole of the pin foot at the same time.

[0007] According to the above technical scheme, the pins of the transformer are inserted into the upper correction holes of the pins and the lower correction holes of the pins. The upper correction plate vibrates back and forth and left and right relative to the lower correction plate. The upper correction holes of the pins are misaligned back and forth and left and right relative to the lower correction holes of the pins. The side walls of the upper correction holes of the pins correct the bending of the upper part of the pins to make the upper part of the pins straight.

[0008] The lower correction plate vibrates back and forth and left and right relative to the upper correction plate, and the lower correction hole of the needle foot is misaligned back and forth and left and right relative to the upper correction hole of the needle foot. The side wall of the lower correction hole of the needle foot corrects the bending of the lower part of the needle foot to make the lower part of the needle foot straight.

[0009] In this way, during the front-back and left-right vibration of the upper correction plate and the lower correction plate, the bent pins are corrected, and the worker removes the transformer from the upper correction plate.

[0010] The upper correction plate limiting structure includes a front limiting plate, a rear limiting plate, a left limiting plate and a right limiting plate installed on the frame, and the front limiting plate, the rear limiting plate, the left limiting plate and the right limiting plate are all installed with horizontal limiting bolts, and the four sides of the upper correction plate are limited by the horizontal limiting bolts of the front limiting plate, the rear limiting plate, the left limiting plate and the right limiting plate. The front and rear and left and right vibrations of the upper correction plate are limited, that is, the vibration amplitude of the upper correction plate is controlled to ensure that the misalignment of the upper correction hole of the pin and the lower correction hole of the pin foot will not be excessive to cause the pin to be bent, thereby ensuring that the straight pin can be accommodated in the upper correction hole of the pin and the lower correction hole of the pin foot at the same time.

[0011] Each limit bolt is equipped with a pair of fastening nuts, which fix the limit bolt on the corresponding limit plate. The pair of fastening nuts can adjust the position of the limit bolt on the limit plate, thereby adjusting the vibration amplitude of the upper correction plate in front and back and left and right directions.

[0012] A vertical limit column is provided on the frame, a threaded hole is provided on the top of the vertical limit column, a vertical limit bolt is screwed into the threaded hole, and limit holes are provided at the four corners of the upper correction plate, the vertical limit bolt passes through the limit holes, and the inner diameter of the limit hole is larger than the outer diameter of the vertical limit bolt. When the upper correction plate vibrates back and forth and left and right, the vertical limit bolt moves back and forth in the limit hole accordingly, and the cooperation between the vertical limit bolt and the limit hole can limit the vibration amplitude of the upper correction plate back and forth and left and right.

[0013] The cross-shaped bracket structure includes a left-right bracket and a front-back bracket, the left-right bracket is superimposed on the front-back bracket, the left and right ends of the left-right bracket are provided with a left convex part and a right convex part, and the front and rear ends of the front-back bracket are provided with a front convex part and a rear convex part; the superimposed left-right bracket and the front-back bracket are clamped by an upper cover plate and a download plate, and the upper cover plate and the download plate are connected by a threaded connector; the lower correction plate is fitted between the left convex part, the right convex part, the front convex part and the rear convex part, and is located above the upper cover plate. Among them, the download plate is fixedly installed on the frame.

[0014] The bottom of the upper cover plate is provided with left and right guide grooves, the top of the lower plate is provided with front and rear guide grooves, the left and right brackets are matched in the left and right guide grooves, and the front and rear brackets are matched in the front and rear guide grooves.

[0015] The vibration unit includes a rotating cylinder mounted on a frame, a cam plate driven by the rotating cylinder, an eccentric rod is provided on the cam plate, a first cam hole is provided in the middle of the left-right bracket, a second cam hole is provided in the middle of the front-back bracket, a cam through hole is provided on the download plate, the cam plate is fitted in the cam through hole, the eccentric rod extends upward into the first cam hole and the second cam hole, the eccentric rod drives the left-right bracket to reciprocate left-right displacement, and the eccentric rod drives the front-back bracket to reciprocate front-back displacement. The rotating cylinder rotates continuously, driving the cam plate to rotate, and the eccentric rod rotates accordingly. Since the center of the eccentric rod deviates from the rotation center of the cam plate, the eccentric rod can drive the left-right bracket to vibrate left-right through the first cam hole, and drive the front-back bracket to vibrate front-back through the second cam hole. Among them, the first cam hole is similar to an ellipse whose left-right axis is shorter than the front-back axis, and the second cam hole is similar to an ellipse whose front-back axis is shorter than the left-right axis.

[0016] The front, back, left and right sides of the cross bracket are all equipped with buffer springs, which are respectively against the front limit plate, the rear limit plate, the left limit plate and the right limit plate. The buffer springs can not only play a buffering role, but also accelerate vibration and improve the efficiency of pin correction.

[0017] The transformer pin correction mechanism of the present invention can automatically correct the pins of a small transformer, is easy to operate and highly efficient. BRIEF DESCRIPTION OF THE DRAWINGS
