Detailed Description
In order to make the technical scheme of the invention clearer, the invention is further described in detail below with reference to the attached drawings and specific embodiments.
First, the sander refers to a mechanical device used when finishing sanding. The sanding and polishing are agreements, and are all methods for enabling materials and objects which are uneven, uneven in thickness and not in accordance with technological requirements to be smoother and even in thickness by means of physical removal of gauze, grinding wheels, sand paper, scouring pad, non-woven fabric polishing wheels and the like, and enabling the materials and objects to reach the technological standards. Meanwhile, the conventional sander generally has only one function of round sand, board sand and wire sand, or only two functions of round sand and board sand.
Referring to fig. 1, as a control method of a sander of the present invention, first, it includes step S100, a mode trigger signal is received by a controller provided in the sander. The mode trigger signals correspond to the working modes of the sander one by one. And the working modes of the sander can specifically comprise three modes, namely a plate sand mode, a round sand mode and a line sand mode.
Meanwhile, when the controller receives the mode trigger signal, the mode trigger signal can be input to the controller by operating a switch provided in the sander in step S001.
In one embodiment, the first switch electrically connected to the controller is provided in the sander, and the mode trigger signals corresponding to different working modes are input by performing different operations on the first switch. Specific: when the first switch is in an on state, a mode trigger signal corresponding to a plate sand mode is input when the first switch is in the on state and reaches a first preset time; when the first switch is in an on state and reaches a second preset time, a mode trigger signal corresponding to a circular sand mode is input; when the switch is in an on state and reaches a third preset time, a mode trigger signal corresponding to the wire sand mode is input. That is, a mode trigger signal corresponding to the board sand mode is input into the controller through long-pressing a first switch arranged in the sander for a first preset time; inputting a mode trigger signal corresponding to the circular sand mode into the controller by pressing the switch for a second preset time; and inputting a mode trigger signal corresponding to the wire sand mode into the controller by pressing the switch for a third preset time. The operation is simple and easy to realize. And, the first switch may be implemented using a relay or an analog switch.
In addition, three switches, namely, a second switch, a third switch and a fourth switch which are electrically connected with the controller can be respectively arranged in the sander. The second switch, the third switch and the fourth switch are respectively arranged in one-to-one correspondence with a plate sand mode, a round sand mode and a line sand mode of the sander. Thus, when the second switch is operated (for example, the second switch is pressed or the second switch is sprung), a mode trigger signal corresponding to the board sand mode is correspondingly input into the controller; when the third switch is operated, a mode trigger signal corresponding to the sand mode is correspondingly input into the controller; when the fourth switch is operated, a mode trigger signal corresponding to the wire sand mode is correspondingly input into the controller. Likewise, the second, third and fourth switches may also be implemented using relays or analog switches.
When a mode trigger signal is input into the controller in any mode, and after the controller receives the mode trigger signal, step S200 is executed, the working mode of the currently triggered sander is judged according to the mode trigger signal, and a corresponding control instruction is sent to a motor of the sander according to the judged working mode, so that the motor is controlled to drive a working chassis of the sander to run a corresponding movement track.
That is, after the controller receives the mode trigger signal, the mode trigger signal corresponds to the working mode of the sander. Therefore, the controller can judge which mode the working mode of the sanding machine is currently triggered is according to the received mode trigger signal. And after the controller judges the working mode of the sanding machine which is triggered currently, a corresponding control instruction is sent to the motor of the sanding machine, so that the motor is controlled to drive the working chassis of the sanding machine to run a corresponding working track. Such as: when the working mode of the sanding machine which is triggered currently is judged to be the board sand mode, the fact that the working chassis is required to be controlled to run the board sand track is indicated, and therefore the controller sends a control instruction for running the board sand track to the motor, and the motor can drive the working chassis to run the board sand track. When the working mode of the currently triggered sander is judged to be a round sand mode or a linear sand mode, the working principle of the sander is the same as or similar to that of the board sand mode, and the working principle is not repeated here.
Specifically, referring to fig. 2, when the controller determines the current triggered working mode of the sander according to the received mode trigger signal, and controls the motor to drive the working chassis to perform a corresponding movement track according to the determined result, the method can be implemented specifically by the following steps.
First, through step S210, the controller determines whether to trigger the first operation mode according to the mode trigger signal. If yes, the working mode of the sander, which is triggered at the moment, is indicated to be a first working mode. Therefore, step S220 can be directly executed, and according to the first working mode, a first control command is sent to the motor to control the motor to drive the working chassis to run a corresponding first movement track. If not, the working mode of the sander is not the first working mode, and further judgment on the working mode of the sander is needed. Therefore, step S230 is performed at this time to further determine whether the second operation mode is triggered. If yes, the working mode triggered at the moment is indicated to be a second working mode. Therefore, step S240 is executed, and according to the second operation mode, a second control command is sent to the motor to control the motor to drive the working chassis to run a corresponding second movement track. If not, the triggered working mode is neither the first working mode nor the second working mode, so that further judgment on the current triggered working mode is needed. That is, step S250 is performed to further determine whether the third operation mode is triggered. If yes, the triggered working mode is the third working mode, so step S260 is executed, and according to the third working mode, a third control instruction is sent to the motor to control the motor to drive the working chassis to run a corresponding third movement track.
By respectively judging all working modes of the sander one by one, the accuracy of a judging result is guaranteed, and finally the reliability of function switching of the sander is effectively improved.
It should be noted that, the first operation mode, the second operation mode and the third operation mode are any one of a plate sand mode, a round sand mode and a line sand mode respectively and are different from each other. Namely, the first working mode can be a plate sand mode, the second working mode is a round sand mode, and the third working mode is a line sand mode; or the first working mode is a round sand mode, the second working mode is a plate sand mode, and the third working mode is a line sand mode; the first working mode can be a linear sand mode, the second working mode can be a plate sand mode, the third working mode can be a circular sand mode and the like. It will be appreciated that the arrangement of the first, second and third modes of operation is not limited to the above.
Referring to fig. 3 to 5, a schematic diagram of a corresponding running track of a sander after different functions (board sand, round sand and line sand) are switched by the sander control method of the present invention. Therefore, by the control method of the sander, the function of the sander is effectively increased, the versatility of the sander is improved, the structure of the sander is simplified, and the production cost of the sander is further reduced.
That is, the control method of the sander of the present invention is configured as described above with respect to the controller of the sander, and when the different functions of the sander need to be switched, only a mode trigger signal corresponding to the working mode to be implemented needs to be input to the controller of the sander. The mechanical structure of the sander is not required to be changed greatly. Therefore, the structure of the sander is effectively simplified while the switching of different functions of the sander can be realized. Finally, the problem that the structure of the sander is complex and only the switching of the two functions of round sand and plate sand can be realized due to the traditional mode of realizing the multifunction of the sander is solved.
Correspondingly, based on the same inventive concept, the invention also provides a sander control system. Because the working principle of the sander control system provided by the invention is the same as or similar to that of the sander control method provided by the invention, repeated parts are not repeated.

And the second control unit 1123 is configured to send a second control instruction to the motor according to the second working mode when the second judging unit 1122 judges that the second working mode is triggered, and control the motor to drive the working chassis to run a corresponding second movement track.
