[0029] A children's toy filling and coating equipment, such as Figure 1 As shown, it includes a workbench 1, a transverse electric slide rail 2 fixedly connected to the workbench 1, a longitudinal electric slide rail 3 arranged on the movable end of the transverse electric slide rail 2, and a slide seat 4 arranged on the movable end of the longitudinal electric slide rail 3, the slide seat 4 is provided with a distance sensor 6 and a centrifugal pump, and also includes a control circuit, the control circuit is coupled to the distance sensor 6, the centrifugal pump, the transverse electric slide rail 2, and the longitudinal electric slide rail 3 respectively, and the control circuit controls the operation of the centrifugal pump, the transverse electric slide rail 2, and the longitudinal electric slide rail 3 according to the feedback of the distance sensor 6.

[0030] The outlet of the centrifugal pump is connected to a nozzle, which is arranged at an angle, and the discharge port of the nozzle is located directly below the distance sensor 6. The inlet of the centrifugal pump is connected to a connecting hose, and the connecting hose is connected to a paint bucket. The centrifugal pump includes a pump body and a centrifugal pump motor 5 connected to it.

[0031] The transverse electric slide 2 includes a transverse track, a transverse screw rod rotatably connected to the transverse track, a transverse seat threadedly connected to the transverse screw rod and slidably connected to the transverse track, and a transverse axis motor 201 fixedly connected to one end of the transverse track and whose output end is transmission-connected to one end of the transverse screw rod. The longitudinal electric slide 3 includes a longitudinal track, a longitudinal screw rod rotatably connected to the longitudinal track, a longitudinal seat threadedly connected to the longitudinal screw rod and slidably connected to the longitudinal track, and a longitudinal axis motor 301 fixedly connected to one end of the longitudinal track and whose output end is transmission-connected to one end of the longitudinal screw rod.

[0032] like Figure 2 As shown, the control circuit includes a voltage comparison circuit 7, a controller 8, and a motor drive circuit 9.

[0033] The input terminal of the voltage comparison circuit 7 is coupled to the distance sensor 6. After the distance signal fed back by the distance sensor 6 is greater than the preset distance reference signal therein, the voltage comparison circuit 7 outputs a comparison signal. The input terminal of the controller 8 is coupled to the output terminal of the voltage comparison circuit 7. After receiving the comparison signal, the controller 8 controls the cross-axis motor 201 and the longitudinal-axis motor 301 to stop, and controls the centrifugal pump motor 5 to operate. The input terminal of the motor drive circuit 9 is coupled to the output terminal of the controller 8. The output terminals of the motor drive circuit 9 are respectively coupled to the centrifugal pump motor 5, the cross-axis motor 201, and the longitudinal-axis motor 301. As Figure 3 shown, the voltage comparison circuit 7 includes an LM339 voltage comparator, the controller 8 includes an STM32F103RCT6 embedded microcontroller, and the motor drive circuit 9 includes a TB67S109AFTG motor drive chip.

[0034] When the present utility model is actually working, a plurality of toy plates are overlapped together so that the holes of all the toy plates can form a hole that can extend to the workbench 1. The controller 8 controls the forward and reverse rotations of the cross-axis motor 201 and the longitudinal-axis motor 301 through the motor drive circuit 9, so that the cross-axis motor 201 can drive the cross screw rod to rotate in the cross rail, and then the cross seat can be displaced in the length direction of the cross rail. Similarly, the longitudinal-axis motor 301 can drive the longitudinal screw rod to rotate in the longitudinal rail, so that the longitudinal seat can be displaced in the length direction of the longitudinal rail, so that the sliding seat 4 can be displaced together with the longitudinal seat. The cooperation of the cross electric slide rail 2 and the longitudinal electric slide rail 3 enables the distance sensor 6 and the centrifugal pump to reach any position on the plane. At this time, when the distance sensor 6 reaches above the holes formed by the combination of all the toy plates, the distance sensor 6 can feed back a distance signal. After this distance signal is given to the voltage comparison circuit 7, it is judged that the distance signal is greater than the distance reference signal. At this time, the voltage comparison circuit 7 feeds back a comparison signal to the controller 8, and the controller 8 will control the cross-axis motor 201 and the longitudinal-axis motor 301 to stop working through the motor drive circuit 9, and control the centrifugal pump motor 5 to work, so that the paint in the paint bucket can enter the centrifugal pump through the connecting hose, and then enter the holes through the nozzle, so as to ensure that the paint can fill the inner walls of the holes where all the toy plates are overlapped together. Then, the cross electric slide rail 2 and the longitudinal electric slide rail 3 both return to their original positions, and the centrifugal pump stops working.

[0035] The above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
