[0012] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0013] In this embodiment of the invention, directional indicators (such as up, down, left, right, front, back, etc.) are only used to explain the relative positional relationship and movement of the components in a specific posture (as shown in the attached figure). If the specific posture changes, the directional indicators will also change accordingly.
[0014] Furthermore, in this utility model, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features.
[0015] Please refer to Figures 1-3 The wireless control device for robot joint motors in this embodiment of the present invention includes a T3A transmitting circuit, an R1A receiving circuit, an MCU, a pre-drive circuit, and a motor unit.
[0016] The R1A receiving circuit, MCU, pre-drive circuit, and motor unit are electrically connected in sequence. An existing microcontroller MCU can be used, such as the STM32 series or GD32 series. The T3A transmitting circuit includes a T3A transmitting module, forward button (SW1), reverse button (SW2), speed control button (SW3), and stop button (SW4). The forward, reverse, speed control, and stop buttons are electrically connected to the T3A transmitting module. The R1A receiving circuit includes an R1A receiving module, a 433MHz wireless RF receiving module mainly used for wireless control in home appliances and smart home scenarios. The T3A transmitting module transmits corresponding wireless control signals based on the triggering of the forward, reverse, speed control, and stop buttons. The T3A transmitting module is a 433MHz wireless RF transmitting module mainly used in smart homes and home appliance remote control, featuring low power consumption and miniaturization. The R1A receiving circuit receives the corresponding wireless control signal and transmits the received command to the MCU.
[0017] In one implementation, the R1A receiving circuit also includes a pairing button (SW5) electrically connected to the R1A receiving module, which allows pairing mode to be entered by double-clicking the pairing button and pairing to be completed by pressing the T3A transmitting module. It supports the 1527 / 2240 / 2262 encoding protocol.
[0018] As one implementation method, please refer to Figure 2 The pre-drive circuit uses the DRV8300DRGER chip. The DRV8300DRGER is a three-phase gate drive chip, mainly used to drive MOSFETs or IGBTs, and supports simultaneous high-side and low-side driving.
[0019] In one implementation, the motor unit includes a three-phase drive circuit (UVW) for the motor; please refer to [reference needed]. Figure 3 .
[0020] The working principle of this utility model is as follows: When the T3A transmitting module presses the SW1 button, the R1A receiving module receives the instruction and transmits it to the MCU. The MCU sends an instruction to the pre-drive, and then the motor starts to rotate forward. Pressing SW3 accelerates the forward rotation, and pressing SW4 stops the motor rotation. Pressing SW2 reverses the motor (the principle is the same as the forward rotation principle), pressing SW3 again accelerates the reverse rotation, and pressing the SW4 button stops the motor rotation. This completes the forward and reverse rotation and speed adjustment of the motor.
[0021] This invention enables wireless control of the joint motor speed of robots in most scenarios.
[0022] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
