A servo drive

Abstract

The present invention relates to the field of industrial control technology, specifically to a servo driver, comprising a device body, a wiring terminal installed on the top of the device body, and a plurality of cross-slot screws threadedly connected to the wiring terminal, wherein the outside of the device body is provided with an anti-wire pulling mechanism.

If a fault occurs when the servo motor is moving, such as the servo motor keeps moving away from the servo driver and exceeds the preset maximum distance, although the two wires will be pulled, the wiring terminals of the servo driver will also quickly loosen the conductor ends of the two wires.

Description

Technical Field

[0001] The invention relates to the technical field of industrial control, in particular to a servo driver. Background Art

[0002] A servo drive is a controller that is mainly used to control electrical equipment related to a servo system, such as a servo motor. At the same time, servo drives are also important structural components in electrical equipment related to a servo system. In the market, some well-known brands of servo drives have high versatility. These brands of drives usually support multiple communication protocols and motion control algorithms, and can control a variety of different brands and models of servo motors.

[0003] When the servo drive is used on the servo motor, it is installed close to the servo motor to reduce the delay and loss of signal transmission. There are two wires connecting the servo drive and the servo motor, which mainly connect the control signal interface of the servo motor and the encoder feedback interface. There are generally three ways to install the servo drive. One is to install it in the control cabinet (for large equipment, which is conducive to ensuring the stability of the entire system), the second is to install it on the servo motor (for small equipment, the wiring distance is short and simple), and the third is to install it inside or outside the equipment (separated from the servo motor, which is conducive to heat dissipation).

[0004] For a servo drive installed inside or outside the device, after being connected to the servo motor, if the servo motor needs to move a small distance in the direction of the X-axis or Y-axis during use to meet specific work requirements, the two wires will swing frequently. The lines connected to the servo drive are generally connected through screw terminals. The long-term and frequent swing of the wires can easily cause the connection between the wires and the servo drive to loosen, affecting the stability of operation. At the same time, if the servo motor fails when moving, such as the servo motor keeps moving away from the servo drive and exceeds the preset maximum distance, the two wires will be pulled and damaged, resulting in damage to the servo drive, and the consequences will be more serious. To this end, we propose a servo drive. Summary of the invention

[0039] The four corners of the bottom of the device body 11 are fixedly connected with mounting plates 6, and the upper ends of the four mounting plates 6 are provided with mounting holes 5; specifically, by providing the mounting plates 6 and the mounting holes 5, it is convenient to install the device body 11 inside or outside the device.

[0040] Working principle: The device body 11 (i.e., the servo driver) is first installed inside or outside the electrical equipment related to the servo system, and close to the servo motor. Separating the device body 11 from the servo motor will facilitate heat dissipation. Then, one end of the two wires is connected to the terminal 10 on the device body 11. Specifically, rotate the corresponding rotating block 30 upward, and the rotating block 30 will drive the corresponding connected threaded column 22 to rotate upward in the corresponding threaded hole 33 on the cross plate 23 (it should be noted that the threaded column 22 will also rotate between the two rubber pads 25, and press the L-shaped rod 15 when rotating the threaded column 22. After the L-shaped rod 15 is pressed, the toothed plate 13, connecting block 12, slide plate 24 and rubber pad 25 connected thereto will be fixed to avoid the friction between the threaded column 22 and the two rubber pads 25, which will cause the two rubber pads 25 and the two slide plates 24 to move when the threaded column 22 rotates). The column 22 will also drive the corresponding connected connection plate 21 and the cross-shaped magnetic block 20 to rotate upward. The cross-shaped magnetic block 20 is inserted into the cross-shaped groove of the corresponding cross-slot screw 19, and the cross-shaped magnetic block 20 can adsorb the cross-slot screw 19, so it can drive the corresponding cross-slot screw 19 to rotate upward until it leaves the terminal 10. At this time, the conductor parts of one end of the two wires can be placed under the corresponding cross-slot screw 19 in turn, and the corresponding rotating block 30 is rotated downward, then the corresponding cross-slot screw 19 will rotate downward and press the conductor parts of one end of the two wires to realize the connection between the wires and the terminal 10. The terminal 10 and the cross-slot screw 19 are both well-known existing technologies and will not be elaborated on.

[0041] Then, the two wires are passed through the two threading holes 8 on the slider 7 and the two hole slots 2 on the fixing plate 3 in turn, and then the two bolts 4 are rotated in turn so that the ends of the two bolts 4 are respectively pressed against the two wires, thereby fixing the two wires. Before fixing, the two wire portions between the slider 7 and the wiring terminal 10 are bent with a large amplitude, rather than being straightened or tightened. Finally, the other ends of the two wires are connected to the servo motor (how to connect the device body 11 and the servo motor is a well-known prior art and will not be elaborated on).

[0042] When the servo motor needs to move a small distance in the direction of the X-axis or Y-axis to meet specific work requirements during use, first, the length of the two wires will meet the movement of the servo motor, but the two wires will swing frequently. At this time, under the locking effect of the two bolts 4 on the two wires, the swinging parts of the two wires are only between the slider 7 and the servo motor, and the swinging force does not act on the connection between the two wires and the terminal 10, thereby avoiding loosening of the connection between the wires and the terminal 10 and affecting the stability of operation.

[0043] If a fault occurs when the servo motor is moving, for example, the servo motor keeps moving away from the device body 11 and exceeds the preset maximum distance, the two wires will be pulled. At this time, under the locking effect of the two bolts 4 on the two wires, the two wires will drive the slider 7 to move toward the fixed plate 3, and the slider 7 will drive the two connecting rods 32 to slide in the fixed plate 3 and squeeze the corresponding two springs 2 31. Under the action of the two springs 2 31, the pulling force can be initially buffered, and the two wire parts that were originally between the slider 7 and the terminal 10 and were bent with a large amplitude will be gradually straightened, and the pulling force will not directly act on the terminal 10 first.

[0044] When the slider 7 moves toward the fixed plate 3, it also drives the square frame 9 to squeeze the inclined plate 1. Under the action of the squeezing force, the inclined plate 1 moves away from the body 11, and drives the square plate 26 to slide away from the body 11 outside the two guide pillars 28, and the square plate 26 squeezes the spring 1 27 connected between the two limit plates 29. When the inclined plate 1 moves away from the body 11, it also drives the L-shaped rod 15 to move together, and the L-shaped rod 15 drives one of the toothed plates 13 connected to it to move together (refer to Figure 2 and Figure 4 ), the driven toothed plate 13 will drive the connecting block 12, the slide plate 24 and the rubber pad 25 connected thereto to move together, and the driven toothed plate 13 will drive the meshing gear 14 to rotate, the gear 14 will drive the connecting column 16 to rotate at the upper end of the U-shaped block 17, and the gear 14 will also push another meshing toothed plate 13 to move, and the moving direction of the other toothed plate 13 is opposite to the moving direction of the L-shaped rod 15, and the connecting block 12, the slide plate 24 and the rubber pad 25 connected to the other toothed plate 13 will also move together, and because the two rubber pads 25 are tightly fitted with the multiple threaded columns 22, then relying on the friction between the two rubber pads 25 and the multiple threaded columns 22 , and according to the moving direction of the two toothed plates 13, it can be known that the two rubber pads 25 can rub the multiple threaded columns 22 to rotate. Because the multiple threaded columns 22 are threadedly connected to the cross plate 23 through the threaded holes 33, the multiple threaded columns 22 will rotate upward, and each threaded column 22 will drive the connecting plate 21 connected to its bottom to rotate upward together with the cross-shaped magnetic block 20. Because the cross-shaped magnetic block 20 is inserted into the cross-shaped groove of the cross-slot screw 19, and the cross-shaped magnetic block 20 can absorb the cross-slot screw 19, it can drive multiple cross-slot screws 19 to rotate upward together, thereby quickly loosening the conductor ends of the two wires, thereby avoiding damage to the device body 11 caused by pulling the two wires, and having good safety.
