Description

Technical Field

[0001] The utility model relates to the technical field of mechanical arm connectors, in particular to a mechanical arm connector and a control system with the connector. Background Art

[0002] The robot arm backup controller is used to control the robot arm when the equipment fails and cannot move normally. It plays an important role in calibration and retracting the robot arm after an error to ensure normal movement.

[0003] The existing robot arm connection solution is to set a connection board on the main device, set multiple sockets on the connection board, and connect the sockets to the motion control baseboard of the main device through cables. The signals of each robot arm are separated and connected to each robot arm on the motion control baseboard. To control a robot arm, the plug of the backup controller needs to be connected to the corresponding socket. However, the plug needs to be manually adjusted on the connection board of the robot arm device, which is inconvenient. In addition, frequent plugging and unplugging will affect the safety and service life of the plug, and there is a risk of damage to the robot arm due to a virtual connection of the plug.

[0004] In summary, there is currently a lack of a connector to improve the aforementioned problems. Utility Model Content

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of them. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0024] Example 1

[0025] In view of the problems existing in the aforementioned prior art, this embodiment provides a robotic arm connector to achieve quick switching of the controlled robotic arm.

[0026] See also Figure 2 The robot arm connector includes a connection switching module 1, one end of the connection switching module 1 is connected to multiple controlled robot arms 2, and the other end of the connection switching module 1 is connected to the control terminal 3. The connection switching module 1 can connect a controlled robot arm to the control terminal 3.

[0027] This embodiment is described by taking four controlled mechanical arms 2 as an example. The connection switching module 1 includes a data selection chip 101 and a switch 102 and an indicator light 103 connected to the data selection chip 101. The multi-channel data input terminals (Y0-Y3) of the data selection chip 101 are electrically connected to the four controlled mechanical arms 2 respectively, the common data channel terminal (Z) is electrically connected to the control terminal 3, and the address input terminals (S0, S1) are electrically connected to the switch 102. In this embodiment, the data selection chip 101 adopts 74HC4051, and other chips that can achieve the same function are also selected as substitutes. 74HC4051 is an 8-channel analog multiplexer / multiplexer with 3 digital selection terminals (S0 to S2, since this embodiment only includes four controlled mechanical arms 2, the S2 terminal is disabled), 1 low-effective enable terminal (E, in this embodiment, the enable state is maintained), 8 independent input / output terminals (Y0 to Y7, where Y4-Y7 are disabled) and 1 common input / output terminal (Z). Depending on the number of controlled robotic arms 2, other 8-way data selection chips, 16-way data selection chips, etc. may also be used as a replacement.

[0028] See also Figure 3 for Figure 2An implementation method of the part connected to the address input terminal, the switching switch 102 is a single-pole four-throw switch, corresponding to the four controlled robotic arms 2 respectively, and the switching switch 102 is connected to four indicator lights 103 respectively. When the switching switch 102 is connected to a controlled robotic arm, the corresponding indicator light 103 lights up to indicate that it is connected. The address setting part is powered by a power supply 104, which can be powered by a battery or a power adapter. By changing the switching switch 102, the operator can output an address that can be understood by the data selection chip 101, thereby turning on the corresponding controlled robotic arm 2. It should be noted that Figure 3 The logic circuit in the figure is for illustration only, and other logic devices (such as AND gate, OR gate, NAND gate, NOR gate, etc.) can be used to implement the same function.

[0029] The connection switching module 1 of the robot arm connector also includes a shell, and the switching switch 102 and the indicator light 103 are respectively connected to the shell and arranged on the same surface of the shell for easy operation.

[0030] For a robot with multiple control signals, a data selector can be configured for each control signal, and the address input terminals of each data selector are respectively connected to Figure 3 The address setting circuit is connected to realize the simultaneous on and off of multiple control signals under the robot arm. For example, for four robots and each robot arm has 11 control signals, the signals (0-10) of the 1# robot arm are connected to Y0 of the 11 data selectors, the 2# robot arms are connected to Y1, 3# to Y2, and 4# to Y3. When the address signal is 00, the 11 data selectors are connected to Y0, and the signals of the 11 1# robot arms are connected to the standby controller.

[0031] In this embodiment, the control terminal 3 can be a computer or a controller. The controller can be an MCU control module, a PLC industrial control module, etc. that are already mature and widely used in the prior art, or other control modules in the prior art that can realize the control function and are suitable for control in this embodiment can be purchased and used, and there is no limitation here.

[0032] The working principle of the robot arm connector is as follows: the operator toggles the switch 102 to the corresponding position, sends the address to the data selection chip 101, connects the corresponding controlled robot arm 2 with the control terminal 3, and thus can control the robot arm at the control terminal 3. The present application can freely switch the controlled robot arm 2, reducing the time consumed by manual plugging and unplugging and the possible damage to the equipment caused by instantaneous virtual connection.

[0033] Example 2

[0034] Compared with Example 1, this embodiment provides another mechanical arm connector to realize the switching of a three-way mechanical arm connector. The mechanical arm connector includes a three-speed multi-way switch, and the three gears are respectively connected to the three-way mechanical arms, and the common end is connected to the backup controller of the control terminal. Specifically, the three-speed multi-way switch can be implemented using a commercially available multi-pole triple-throw switch. The solution of this embodiment is suitable for scenarios where the number of controlled mechanical arms is small and the number of control signal lines for each mechanical arm is small.

[0035] Example 3

[0036] Based on Example 1, see Figure 1 This embodiment provides a robot control system, comprising a plurality of controlled robot arms 2, a control terminal 3, and a robot connector as described in Example 1, wherein one end of the robot connector is respectively connected to the motion control base plates of the plurality of controlled robot arms 2, and the other end is connected to the standby controller of the control terminal 3. The connection switching module 1 is respectively connected to the controlled robot arms 2 and the control terminal 3 through a signal line 4.

[0037] Preferably, the robot arm connector is connected to each controlled robot arm 2 via a motion control base plate, wherein the motion control base plate is used to divide the signal line 4 into a plurality of sub-circuits and connect them to each controlled robot arm 2 .

[0038] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various equivalent modifications or replacements within the technical scope disclosed by the utility model, and these modifications or replacements should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
