[0002] With the rapid development of the electronics industry, printed circuit boards (PCBs) have been used more and more widely. In the PCB production process, lamination is an important process. During the lamination process, steel plates are needed to overlap two adjacent PCB semi-finished products. Since they are the only material that comes into direct contact with the multi-layer circuit board during the lamination process, their quality directly affects the quality of the multi-layer circuit board after lamination. Since the surface of the steel plate is very easy to adhere to the semi-cured sheet powder and glue flow after lamination, the steel plate needs to be polished and cleaned after each use. The current steel plate grinding equipment must wait until the steel plate is polished and enters the cleaning machine before it can be fed again.

The grinding group 330 and the second conveying wheel group 340; the first conveying wheel group 310 includes a first conveying wheel and a thickness sensor, the thickness sensor is arranged in the middle of the first conveying wheel group 310, and is used to measure the thickness of the steel plate; the first grinding group 320 includes a first upper grinding roller, a first lower grinding roller and a third sensor, the third sensor is used to detect the steel plate, the first grinding group 320 is also provided with a first adjustment mechanism for adjusting the vertical distance between the first upper grinding roller and the first lower grinding roller, the first upper grinding roller is connected to the first adjustment mechanism, and the first adjustment mechanism can The first upper grinding roller is driven toward or away from the first lower grinding roller; the second grinding group 330 includes a second upper grinding roller, a second lower grinding roller and a fourth sensor, the fourth sensor is used to detect the steel plate, and the second grinding group 330 is also provided with a second adjustment mechanism for adjusting the vertical distance between the second upper grinding roller and the second lower grinding roller.

The input end of the second conveyor 400 is provided with a fifth sensor, the fifth sensor is used to detect the steel plate; the cleaning machine 500 is adjacent to the second conveyor 400 and is used to clean and dry the steel plate sent from the second conveyor 400; the controller is used to control the operation of the steel plate grinding equipment.

[0043] It can be understood that the multiple sensors in the steel plate grinder can accurately obtain the position of each steel plate and the working status of each machine. The controller controls each machine of the steel plate grinding equipment according to the obtained information. When the first conveyor 100 feeds the plate, the steel plate turner 200 turns the steel plate, the automatic grinder 300 grinds the steel plate, and the second conveyor 400 conveys the steel plate to the cleaning machine 500; when the first conveyor 100 conveys the steel plate to the steel plate turner 200, the steel plate turner 200 conveys the steel plate to the automatic grinder 300, the automatic grinder 300 measures the thickness of the steel plate and conveys the ground steel plate to the second conveyor 400, and the cleaning machine 500 cleans the steel plate; the waiting time between machines is reduced, and production efficiency is improved.

[0044] It should be noted that the first conveyor 100 is a conveyor composed of plastic rollers, which has a smaller contact area with the steel plate, and can prevent the surface of the steel plate from being scratched during transportation; during the PCB board pressing process, the lower surface of the steel plate is more likely to adhere to semi-cured sheet powder and glue flow, and turning the steel plate by the steel plate turning machine 200 can improve the cleaning effect; the setting of the first adjustment mechanism and the second adjustment mechanism enables the automatic grinder 300 to grind steel plates of different thicknesses. After automatically measuring the thickness of the steel plate, the first adjustment mechanism and the second adjustment mechanism adjust the grinding gap so that the first upper grinding roller and the second upper grinding roller are more in line with the upper surface of the steel plate to obtain a better cleaning effect; the type of sensor in the embodiment of the present invention can be but is not limited to a photoelectric sensor or a mechanical switch; wherein the photoelectric sensor can be a photoelectric direction switch, whose working principle is to use the obstruction or reflection of the light beam by the detected object to detect the presence or absence of the object.

[0045] It should be noted that the steel plate grinding equipment may only include the first conveyor 100, the automatic grinder 300, the second conveyor 400 and the cleaning machine 500. Accordingly, the first adjustment mechanism in the automatic grinder 300 is connected to the first lower grinding roller, and the second adjustment mechanism is connected to the second lower grinding roller.

[0046] According to the steel plate grinding equipment provided by the embodiment of the first aspect of the present invention, the second conveyor 400 includes a transverse conveying component and a longitudinal conveying component. The transverse conveying component and the longitudinal conveying component cooperate to convey the steel plate to the cleaning machine 500. The second conveyor 400 is also provided with a sixth sensor for detecting the longitudinal conveying component.

[0047] It should be noted that the transverse conveying component is a roller conveyor, and the longitudinal conveying component is a belt conveyor. The longitudinal conveying mechanism can be raised and lowered in the vertical direction. Since the cleaning machine is located at the corner of the second conveyor 400, the transverse conveying component is required to convey the steel plate transversely to the preset position. The longitudinal conveying mechanism then rises to lift the steel plate and separate it from the transverse conveying component. Finally, the longitudinal conveying mechanism conveys the steel plate longitudinally into the cleaning machine 500.

[0048] According to the steel plate grinding equipment provided by the embodiment of the first aspect of the present invention, spray pipes for washing the steel plates are provided on both sides of the first grinding group 320 and the second grinding group 330; in order to avoid damage to the second conveyor 400 due to moisture on the steel plates, the automatic grinder 300 is also provided with a drying component 350 for drying the steel plates, and the drying component 350 is connected to the second conveying wheel group 340.

[0049] It is understood that most impurities adhering to the steel plate can be removed by the grinding action of the grinding rollers, and the spray pipe can rinse the surface of the steel plate clean to prevent impurities from reattaching. The drying assembly 350 includes a hot air blower and a sponge. The hot air blower is mounted near one end of the second conveyor wheel assembly 340, and the sponge is fixedly connected to the discharge port of the automatic grinder 300. The hot air blower is used to dry the surface of the steel plate, and the sponge is used to wipe the surface of the steel plate to further dry the steel plate.

[0050] Reference Figure 3 The control method of the steel plate grinding equipment according to the embodiment of the present invention is described. The control method is applicable to the steel plate grinding equipment according to the above embodiment. The specific structure of the steel plate grinding equipment can be found in Figure 1 and Figure 2 The embodiment shown is not described in detail here. The control method is described below with a specific example.

[0051] Since the working cycles of various machines are different, in order to avoid the stacking or collision of multiple steel plates during the operation of the steel plate grinding equipment, it is necessary to ensure that the next step is carried out after the process is completed.

[0052] Specifically, refer to Figure 3 The control method of the embodiment of the present invention includes but is not limited to the following steps:

[0053] When the first sensor and the third sensor detect the steel plate at the same time, the first conveyor 100 is controlled to convey the steel plate to the steel plate turning machine 200;

[0054] When the sixth sensor detects that the longitudinal conveying assembly is reset, the steel plate turning machine 200 is controlled to turn the steel plate, and the second motor is controlled to start, so that the first grinding group 320 and the second grinding group 330 grind the steel plate;

[0055] When the fifth sensor detects the steel plate, the steel plate turning machine 200 is controlled to convey the steel plate to the automatic grinding machine 300, and the first motor is controlled to start, so that the first conveying wheel group 310 conveys the steel plate and the thickness sensor measures the thickness of the steel plate;

[0056] When the second sensor and the fourth sensor detect the steel plate at the same time, the first motor is controlled to stop, so that the first conveying wheel assembly 310 and the first grinding assembly 320 stop working.

[0057] It can be understood that when the first sensor and the third sensor detect the steel plate at the same time, that is, the steel plate turner 200 has conveyed the steel plate to the automatic grinder 300, so the first conveyor 100 is controlled to convey the steel plate to the steel plate turner 200; when the second sensor and the fourth sensor detect the steel plate at the same time, in order to avoid the collision of the two steel plates in the automatic grinder 300, the first motor is controlled to stop; when the fifth sensor detects the steel plate, that is, the steel plate in the automatic grinder 300 has been conveyed to the second conveyor 400, so the first motor is controlled to start, so that the first conveying wheel group 310 conveys the steel plate and the thickness measuring sensor measures the thickness of the steel plate; when the sixth sensor detects that the longitudinal conveying component is reset, that is, the second conveyor 400 has conveyed the steel plate to the cleaning machine 500, there are unturned steel plates in the steel plate turner 200, and there are unground steel plates in the automatic grinder 300, so the steel plate turner 200 is controlled to flip the steel plate, and at the same time the second motor is controlled to start, so that the first grinding group 320 and the second grinding group 330 grind the steel plate. The embodiment of the present invention uses multiple sensors to accurately obtain the position of each steel plate and the working status of each machine, and controls each machine of the steel plate grinding equipment based on the obtained information, so that each machine cooperates with each other, ensures that each machine works in an orderly manner, reduces the waiting time between each machine, and improves production efficiency.

[0058] The embodiments of the present invention are described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Various changes can be made within the scope of knowledge possessed by ordinary technicians in the technical field without departing from the scope of the present invention.
