[0022] See also Figures 1 to 6In this embodiment, a welding robot motion controller that is easy to maintain and reduces the cost of use includes a controller housing 1 and a functional module 2. A controller mainboard 3 and a module mounting plate 4 are fixedly installed inside the controller housing 1. A mounting and fixing mechanism is provided between the functional module 2 and the module mounting plate 4. The mounting and fixing mechanism includes a strip plate 5 fixedly installed on the surface of the opposite side of the functional module 2. A receiving cavity 6 is opened inside the strip plate 5. A spring 7 is fixedly installed inside the receiving cavity 6. A connecting block 8 that is slidably installed in the receiving cavity 6 is fixedly installed at one end of the spring 7. A fixing pin 9 that penetrates the outer surface of the strip plate 5 is fixedly installed on the surface of the connecting block 8 away from the spring 7. A positioning block 10 is fixedly installed on the surface of the strip plate 5 away from the fixing pin 9. An installation groove 11 is provided on the upper surface of the plate 4. There are multiple installation grooves 11, and the multiple installation grooves 11 are evenly distributed on the upper surface of the module installation plate 4, which is convenient for installing multiple functional modules 2 to meet the different usage requirements of the controller. Two fixing grooves 12 are provided on one side surface inside the installation groove 11, and a positioning groove 13 corresponding to the fixing groove 12 is provided on one side surface inside the installation groove 11. A connecting rod 14 that passes through the upper surface of the strip plate 5 is fixedly installed on the upper surface of the connecting block 8, and a movable plate 15 is fixedly installed on the top of the connecting rod 14. A strip hole 16 connected to the accommodating cavity 6 is provided on the upper surface of the strip plate 5. The connecting rod 14 is located in the strip hole 16, which facilitates the movement of the connecting block 8 in the accommodating cavity 6 and facilitates the extension and retraction of the fixing pin 9.

[0023] A first contact pole 17 is fixedly installed on the surface of the positioning block 10 away from the strip plate 5, and a second contact pole 18 is fixedly installed inside the positioning groove 13. The first contact pole 17 is electrically connected to the output end of the functional module 2, and the second contact pole 18 is electrically connected to the input end of the controller main board 3. By setting the first contact pole 17 and the second contact pole 18, the connection between the functional module 2 and the controller main board 3 is facilitated.

[0024] The inner surface of the mounting groove 11 is provided with a strip groove 19 and a heat dissipation hole 20. The number of the strip grooves 19 and the heat dissipation holes 20 is multiple and evenly distributed on the inner surface of the mounting groove 11. The strip groove 19 is coated with thermal grease 21. A cooling fan 22 connected to the interior of the controller housing 1 is fixedly installed on the outer surface of the controller housing 1. A heat dissipation port 23 with a dustproof net fixedly installed inside is provided on the surface of the controller housing 1, which is beneficial to improving the heat dissipation effect between the interior of the controller housing 1, the functional module 2 and the controller mainboard 3.

[0025] The controller housing 1 consists of an upper shell 24 and a lower shell 25. The upper shell 24 is snap-fitted to the top of the lower shell 25. The surface of the upper shell 24 is provided with control buttons and a display screen for conveniently setting the parameters of the controller.

[0026] The working principle of the above embodiment is:

[0027] When in use, first insert the positioning block 10 into the positioning groove 13, so that the first contact pole 17 contacts the second contact pole 18, so that the functional module 2 is connected to the controller main board 3, and then move the movable plate 15 to retract the fixing pin 9 into the accommodating cavity 6, so that the spring 7 is compressed, and then the functional module 2 and the strip plate 5 are inserted into the installation groove 11 away from the side of the positioning block 10. At this time, the fixing pin 9 corresponds to the fixing groove 12, and the movable plate 15 is released. Under the action of the spring 7, the fixing pin 9 is nailed into the fixing groove 12, and the installation of the functional module 2 can be completed. After the functional module 2 is installed, the surface of the functional module 2 contacts the thermal grease 21. During use, the heat on the surface of the functional module 2 is guided by the thermal grease 21. At the same time, the cooperation of the cooling fan 22 and the heat dissipation port 23 can dissipate heat inside the controller housing 1.

[0028] The control method of the present invention is to control through a controller. The control circuit of the controller can be implemented by simple programming by technicians in this field. The provision of power is also common knowledge in this field. In addition, the present invention is mainly used to protect mechanical devices, so the control method and circuit connection are no longer explained in detail in the present invention.
