Description

Technical Field

[0001] The utility model relates to a terminal installation device, in particular to a high-stability terminal quick insertion machine. Background Art

[0002] There are many stator enameled wire connection solutions in our household appliance motor industry. The Magmate structure terminal is one of them. The Magmate terminal can be conveniently and reliably used to connect the motor enameled wire and the power cord, but most companies still use manual crimping to produce. The purchased whole tray of terminals is first manually decomposed into a single group (one or several consecutive) of terminals, and then manually placed into the terminal hole of the stator, and then a small manual pressing tool is used to press the terminal into place. This operation requires at least three steps, which is time-consuming and labor-intensive, and has low production capacity. There are also a few automatic terminal crimping machines on the market, but the feeding mechanism of the terminal adopts a mechanical push rod test, which has a complex mechanism, poor stability, and inconvenient maintenance and adjustment; the cutting mechanism and the pressing mechanism use the same cylinder, and the stroke of the cutting mechanism and the pressing mechanism is difficult to adjust. Because the same cylinder drives the two mechanisms to move at the same time, once the cutting mechanism is stuck but the pressing mechanism continues to move, it will cause damage to the terminal knife box and the blade, and the downtime rate is high. Therefore, it is urgent to develop an automatic terminal insertion device that can work efficiently and stably to meet the use needs. Utility Model Content

DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and embodiments, but they are not intended to limit the present invention.

[0023] A cushion block 311 is provided between the female punching blade 310 and the bracket 1 .

[0024] A wear-resistant copper strip 312 is further provided between the pressing block 303 and the sliding block 302 .

[0025] The terminal pressing mechanism 5 includes a pressing cylinder 501 fixed to the top of the bracket 1 , a floating joint 502 is provided below the pressing cylinder 501 , a terminal pressing blade 503 is provided below the floating joint 502 , and the terminal pressing blade 503 corresponds to the terminal guide box 4 .

[0026] The terminal conveying mechanism 6 comprises a feeding servo motor 601 fixed to the inner wall of the bracket 1 , a reducer 602 is arranged below the feeding servo motor 601 , a feeding gear 603 is arranged below the reducer 602 , and the feeding gear 603 matches with the terminal.

[0027] A method for using a high-stability terminal rapid insertion machine comprises placing strip terminals in a terminal conveying trough, wherein a feeding gear of a terminal conveying mechanism meshes with the terminals, and the strip terminals are sequentially fed into a terminal transverse feeding trough of a terminal guide box through the terminal conveying mechanism, and the servo motor of the terminal conveying mechanism drives the feeding gear to rotate a corresponding angle to control the number of terminals fed into the terminal transverse feeding trough, and a corresponding number of terminals are cut off through a terminal cutting mechanism, and then the cut terminals are pressed into the terminal holes of the motor along the terminal guide box through a terminal pressing mechanism.

[0028] A stroke adjustment nut is also provided on the top of the cutting cylinder, and a connecting screw is provided at the output end below the cutting cylinder, and the connecting screw matches the stroke adjustment nut.

[0029] The terminal conveying trough is provided with a disc-shaped continuous terminal, and the terminal is provided with a groove matched with the feeding gear, and the two can mesh with each other to realize the transmission.

[0030] The specific working process of the utility model is as follows: the terminal strip is placed in the terminal conveying trough, the feeding gear of the terminal conveying mechanism is meshed with the terminal, the strip terminals are sequentially fed into the terminal transverse feeding trough of the terminal guide box through the terminal conveying mechanism, a corresponding number of terminals are cut off through the terminal cutting mechanism, and then the cut terminals are pressed into the terminal holes of the stator along the terminal guide box through the terminal pressing mechanism.

[0031] Working process of the terminal conveying mechanism: the feeding servo motor works, driving the reducer to work, and then driving the feeding gear to rotate. The rotation of the feeding gear will drive the terminal engaged with it (the tooth structure of the feeding gear matches the terminal groove) to move, and drive the terminal to move along the terminal conveying trough to the terminal horizontal feeding trough, corresponding to the vertical through grooves in the terminal guide box.

[0032] The terminal conveying mechanism adopts a servo motor plus a planetary reducer to drive the feeding gear. Based on the advantages of the servo motor, the position and speed of the terminal feeding are adjustable and controllable, which improves the stability of the feeding. At the same time, because the servo motor has torque feedback, it can give a timely warning when the feeding is not smooth, and the operator can deal with it in time, which can effectively prevent the problem of material jamming in the cutting mechanism.

[0033] Working process of the terminal cutting mechanism: The cutting cylinder works, driving the slider to move along the upper and lower slideways formed between the two pressure blocks, and then driving the lever to rotate around the rotation center (the needle bearing is provided with a lever pin, and the lever forms a rotation point), so that the lower end of the lever rotates to the corresponding position, and the drive shaft and the tool holder assembly move toward the terminal, and then drive the male punching cutter fixed on the tool holder assembly to cut the terminal, and cooperate with the female punching cutter to achieve the punching of the terminal. After the punching is completed, the cutting cylinder drives the slider to rise, and then drives the lever to rotate around the rotation center, and the lower end of the lever moves away from the terminal, and then drives the male punching cutter away from the terminal and separates from the terminal to achieve the cutting operation of the terminal. After the cutting is completed, the terminal will fall along the vertical through groove to the bottom of the vertical through groove, waiting for subsequent pressing.

[0034] The terminal pressing blades are a plurality of pressing pieces corresponding to the positions of the vertical through slots.

[0035] Working process of the terminal pressing mechanism: the pressing cylinder works, driving the floating joint to move downward, and then driving the terminal pressing blade to press down the terminal in the vertical through groove, so that the terminal is pressed into the terminal hole of the motor.

[0036] The terminal cutting mechanism and the pressing mechanism are controlled by corresponding cylinders respectively. The cylinder of the terminal cutting mechanism adopts an adjustable stroke cylinder. By adjusting the stroke of the cylinder, the moving position of the cutting knife can be controlled. The terminal cutting mechanism cylinder is also equipped with a magnetic switch. The PLC will control the action of the pressing cylinder only after receiving the in-position signal of the cutting cylinder. At this time, if the cutting is abnormal and the terminal is not effectively cut, the cutting cylinder is not in place and the magnetic switch has no signal output, and the pressing cylinder does not move. Such an action process can effectively avoid the expansion of the problem and minimize the damage to the knife box and the blade.
