[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] Embodiment: As Figures 1-6As shown in the figure, the drive and control integrated machine convenient for maintenance includes a housing 1 and a circuit board group 2 accommodated in the housing 1. The circuit board group 2 includes a main control board 201, a secondary control board 202, and several drive boards 203. Each drive board 203 is connected to the main control board 201 and is independently controlled by the main control board 201. Each drive board 203 has external connection terminals 204 with at least part of them extending out of the housing 1. The external connection terminals 204 are used to connect to motors (such as servo motors) or sensors. The secondary control board 202 is arranged on one side of the main control board 201 and is controlled by the main control board 201. Among them, a single-chip microcomputer (not marked in the figure) is integrated on the main control board 201. The single-chip microcomputer is connected to the drive board 203 through the first row of pins 3. The drive board 203 is controlled by the single-chip microcomputer. The single-chip microcomputer transmits motion instructions to the drive small board through the first row of pins 3, so that the servo motor operates according to the received motion instructions. When the drive and control integrated machine convenient for maintenance is used in cooperation with a multi-axis manipulator, multiple servo motors are respectively connected to multiple external connection terminals 204. This embodiment provides a drive and control integrated machine convenient for maintenance to solve the problem that in the existing drive and control integrated machine, the access terminals of multiple servo motors are arranged on the same control board. When a fault occurs in one servo motor access terminal, it affects all servo motor access terminals, resulting in the failure of the multi-axis manipulator to move. It mainly configures multiple drive boards 203 independently controlled by the main control board 201 in the housing 1. Each drive board 203 has external connection terminals 204 with at least part of them extending out of the housing 1 to connect to motors (such as servo motors). Since multiple external connection terminals 204 are arranged on multiple drive boards 203 independently controlled by the main control board 201, multiple servo motors paired with multiple external connection terminals 204 one by one are independently controlled and do not affect each other. That is, when one external connection terminal 204 is damaged, other servo motors are not affected. It has good anti-interference ability, good versatility, strong compatibility, and is convenient for maintenance. Also, because one external connection terminal 204 is configured on one drive board 203, the drive board 203 has a small volume. And the small volume of the drive board 203 is beneficial to heat dissipation, and has low cost and simple installation.

[0026] More specifically, the secondary control board 202 has secondary connection terminals 205 with at least part of them extending out of the housing 1. The secondary connection terminals 205 are used to connect to control cylinders. The main control board 201 has main connection terminals 207 with at least part of them extending out of the housing 1. The single-chip microcomputer is signal-connected to the secondary control board 202 through the second row of pins (not marked in the figure). The secondary control board 202 is controlled by the single-chip microcomputer. The single-chip microcomputer can control the secondary control board 202 to perform IO signal input (collecting external sensor signals), or control the secondary control board 202 to perform IO signal output (controlling the operation of the cylinder).

[0027] More specifically, a switching power supply (not marked in the figure) is integrated on the main control board 201. The switching power supply can generate two 24V voltages, and then generate voltages such as 15V, 5V, and 3.3V through the DCDC buck power supply and the LDO power supply for the use of the drive board 203 and the secondary control board 202.

[0028] The main control board 201 is integrated with a computing core, as well as a bus voltage acquisition circuit, a mains power failure detection circuit, a start relay control circuit, five driver board communication circuits, a back electromotive force discharge circuit, a radiator temperature acquisition circuit, an external isolation input circuit, and an external isolation output circuit, which are respectively connected to the computing core. Among them, the bus voltage acquisition circuit, the mains power failure detection circuit, the start relay control circuit, the five driver board communication circuits, the back electromotive force discharge circuit, the radiator temperature acquisition circuit, the external isolation input circuit, and the external isolation output circuit are existing circuits well known to those skilled in the art, and will not be described in detail here to avoid redundancy.

[0029] Among them, the computing core uses a GD32F103RCT6 type MCU chip, which is used for data interaction of motion instructions and states with the driver board 203.

[0030] It should be noted that the external connection terminals 204, the secondary connection terminals 205, and the main connection terminals 207 are existing wiring ports, and the switch power supply, the single-chip microcomputer, and the chips integrated on the main control board 201, the secondary control board 202, and the driver board 203 are all existing technologies well known to those skilled in the art, and will not be described in detail here to avoid redundancy.

Since several driver boards 203 are arranged side by side in the front-back direction, and several driver boards 203 and the secondary control board 202 are respectively arranged on the left and right sides of the main control board 201, the main control board 201, the secondary control board 202, and several driver boards 203 are reasonably arranged in the housing 1, which is convenient for the external connection terminals 204 to be connected to the servo motor.

[0032] In the embodiment of the present invention, the driver board 203 is connected to the main control board 201 through the first row of pins 3, the driver board 203 is perpendicular to the main control board 201, the secondary control board 202 is connected to the main control board 201 through the copper column 208, and the secondary control board 202 is parallel to the main control board 201.

Several driving boards 203 are arranged side by side in the length direction of the housing 1 and at least part of them faces the inspection opening 106. An exposed opening 107 for the external terminal 204 to insert into and extend out of the housing 1 is formed on the cover plate 105. Since the inspection opening 106 faces the bottom of the receiving cavity 103 and several driving boards 203 are arranged side by side in the length direction of the housing 1 and at least part of them faces the inspection opening 106, it is convenient for the disassembly, assembly and maintenance of the driving board 203.
