Fig. 1 schematically shows a schematic view of a sander in the related art.

As shown in Fig. 1, in the related art, the sanding machine is provided with only the sanding portion, that is, the sander body 101 and the switch 102, and the detecting portion is not provided, so that the worker performs the grinding process using the sander provided by the related art body. Since there is no detection part, it is impossible to detect in real time and indicate to the worker whether the operation is appropriate, and the grinding operation of the worker is not supervised and guided, so that the polishing quality between different individuals is different.

2A-2C illustrate schematic views of several sanders in accordance with an embodiment of the present disclosure, which will be described in detail below with reference to FIGS. 2A-2C.

As shown in FIGS. 2A-2C, the sander includes a sander body 201, a switch 202, an inductive device 203, and a display 204. among them:

The sander body 201 is used to polish the object to be polished.

In the embodiment of the present disclosure, the sander may be various types of sanders, which are not limited herein, and may be, for example, a pneumatic sander or an electric sander.

It should be noted that in the embodiment of the present disclosure, the object to be polished may include a plurality of types, which are not limited herein. For example, the object to be polished may be the housing of the vehicle. Generally, before the vehicle casing is painted, it needs to be ground to facilitate uniform painting.

The switch 202 is connected to the sander body 201 for controlling the magnitude of the rotational speed of the sander according to the size of the opening of the switch 202.

In the embodiment of the present disclosure, the switch 202 may be various types of switches, which are not limited herein. For example, corresponding to the type of the sander, when the sander is a pneumatic sander, the switch 202 is a pneumatic switch. When the sander is an electric sander, the switch 202 is an electric switch.

Specifically, the switch 202 may be disposed on the sander body 201, for example, as shown in FIGS. 2A-2C, and may be disposed at the top end of the sander body 201.

In use, the worker can hold the sander body 201 by hand, and the sanding head of the sander body 201 (shown in FIG. 2A includes a sanding disc tray a and a sanding disc b mounted on the sanding disc tray a) Align the portion to be polished of the object to be polished (as shown in FIG. 2A, polish the surface c), and control the rotation speed of the sander by controlling the closing angle of the switch to achieve the purpose of controlling the grinding efficiency.

Excessive pressure applied to the sander can result in excessive sanding; too little pressure applied to the sander can result in insufficient sanding. Excessive grinding or insufficient sanding indicates that the worker's level of grinding is not high, which will cause the polishing quality of the object to be polished to decrease. Therefore, to ensure the quality of the grinding, it is necessary to monitor and guide the grinding operation of the worker, especially the pressure applied to the grinding machine.

The sensing device 203 is coupled to the switch 202 or the sander body 201 for sensing the magnitude of the pressure applied to the sander.

Here, the sensing device 203 may be various types of sensing devices, which are not limited herein, and may be, for example.

It should be noted that in the embodiment of the present disclosure, the sensing device 203 may include multiple types, which are not limited herein. For example, the sensing device 203 may include a pressure sensor, and further, the pressure sensor may include a button sensor or a film sensor.

In addition, in the embodiment of the present disclosure, the sensing device 203 may be disposed on the switch 202 or may be disposed on the sander body 201, which is not limited herein.

The display 204 is coupled to the sensing device 203 for displaying the pressure applied to the sander based on at least the sensing results of the sensing device 203.

It should be noted that display 204 can be either an analog display or a digital display. If it is an analog display, the information corresponding to the analog pressure signal collected by the sensing device 203 can be directly displayed; if it is a digital display, the analog pressure signal collected by the sensing device 203 can be analog-digital converted to obtain a corresponding digital pressure signal, and then the number is displayed. The information corresponding to the pressure signal.

In addition, the design form of the display 204 may include a plurality of types, which are not limited herein. For example, it may be small and independent of the display device other than the sander body 201, or it may be disposed on the sander body 201 and integrated with the sander body 201.

During work, the hand applies pressure on the body and switch of the sander, starts the sander to grind, and applies the pressure exerted on the sander by hand, and presses the sanding disc onto the surface to be polished by sanding the disc tray. The grinding machine drives the sanding disc tray to rotate by the driving of the internal motor, and the sanding disc tray drives the sanding disc to perform a relative frictional movement with the polished surface to grind and remove the polished surface. By controlling the pressure between the sanding disc and the surface to be polished, it is possible to control the amount of sanding and removal of the surface to be polished per unit time. Therefore, by controlling the pressure applied to the sander, it is possible to control the amount of sanding removal in the unit.

In production, workers can prevent excessive sanding and wear defects by controlling the pressure exerted by the hand on the sander.

Through the embodiment of the present disclosure, since the corresponding sensing device 203 and the display 204 are provided as the detecting portion of the sander to cooperate with the sanding portion of the sander, the sanding machine and the system thereof are used for polishing by the worker. In the process, the detection part can detect in real time and indicate to the worker whether the operation is appropriate, thereby improving the quality of the worker's polishing and reducing the difference in polishing quality between different individuals.

For example, when the pressure sensor is selected to be mounted on the surface A of the switch 202 as shown in FIG. 2A, the sanding pressure applied to the switch 202 can be applied to the sanding tool itself by pressing the pressure sensor mounted on the switch by the palm of the hand ( That is, the sander body 201) can simultaneously measure the sanding pressure applied to the sanding tool (ie, the sander) by the pressure sensor.

For example, when the pressure sensor is selected to be mounted on the surface B of the switch 202 as shown in FIG. 2B, the sanding pressure applied to the switch 202 can be pressed by the palm of the hand, and then transmitted to the pressure sensor mounted on the switch, and the grinding pressure is applied. It is passed to the sanding tool itself, and the pressure applied to the sanding tool can be measured by the pressure sensor.

For example, when the pressure sensor is selected to be mounted on the surface C of the sander body 201 as shown in FIG. 2C, the sanding pressure applied to the switch 202 can be pressed by the palm of the hand and transmitted to the pressure sensor mounted on the body, and then The sanding pressure is transmitted to the sanding tool itself (i.e., the sander body 201), and the sanding pressure applied to the sanding tool can be measured by the pressure sensor.

Preferably, the sensing device 203 can be mounted in a mounting manner as shown in Figure 2A, such that it does not affect the normal use of the switch 202, but can accurately detect the pressure applied to the sander. Selecting the mounting means 203 as shown in Figures 2B and 2C has a slight effect on the normal use of the switch 202, and the accuracy of detecting the pressure applied to the sander is also affected.
