Description

Technical Field

[0002] Suction cups are intermediate objects that use the principle of atmospheric pressure to fix two objects together. For example, in the construction and decoration industry, when flat materials such as tiles, doors and windows need to be moved, they are often moved manually. Before moving, workers must not only wear protective equipment, but also separate the stacked flat materials. These stacked flat materials are not only adsorbed together and difficult to separate, but also have smooth surfaces. If you are not careful, they can easily slip from your hands, causing them to break and increase the defective rate. Therefore, during the transportation of these flat materials, suction cups are often used as auxiliary tools to achieve transportation. Using suction cups to suck tiles, doors and windows, etc., and then holding the suction cups for transportation is a very good way.

When the power supply unit 120 and the mounting portion 121 are installed, an electrical connection is formed between the second conductive sheet and the first conductive sheet.

[0053] like Figure 4 As shown, the first end and the second end of the handle portion 100 are respectively provided with a first connecting portion 130. Specifically, one of the first connecting portions 110 at the first end of the handle portion 100 is located in the accommodating portion 110, and the second end of the handle portion 100 may also be provided with an accommodating portion, and the other first connecting portion 110 at the second end of the handle portion 100 may be located in the accommodating portion of the second end.

[0054] like Figure 1 As shown, the base part 200 is the part that contacts the object to be transported. After the base part 200 contacts the surface of the object to be transported, the air pump part 300 uses the atmospheric pressure principle to adsorb the object to be transported onto the base part 200.

[0055] like Figure 6As shown, the base portion 200 includes a substrate 210, a vacuum seal 220, a first receiving member 230 and a second receiving member 240.

[0056] like Figure 3 and Figure 6 As shown, the first receiving member 230 and the second receiving member 240 are arranged on the second side of the substrate 210. For example, the first receiving member 230 and the second receiving member 240 can be connected to the substrate 210 by screws, bolts, adhesives or snap-fit ​​devices. The first receiving member 230 and the second receiving member 240 correspond to the first end and the second end of the handle portion 100, respectively, and can be partially located in the accommodating portions at both ends of the hand 100.

[0057] like Figure 6 and Figure 7As shown, the base portion 200 is provided with an air suction hole 212 and a second connection portion 250 detachably connected to the first connection portion 130. Specifically, the base plate 210 of the base portion 200 is provided with an air suction hole 212 at a position corresponding to the first end of the handle portion 100 (that is, the air suction hole 212 is located on the base plate 210), and the first receiving member 230 is provided with a first connecting hole 231 connecting the air pump portion 300 and the air suction hole 212. By respectively providing the first connection portion 130 at the first end and the second end of the handle portion 100, and respectively providing the second connection portion 250 detachably connected to the first connection portion 130 on the first receiving member 230 and the second receiving member 240 of the base portion 200. 50, so that the handle part 100 and the base part 200 can be disassembled, so as to replace the handle part 100 or the base part 200; and when the first connecting part 130 is connected to the second connecting part 250, the air pump part 300 is connected to the air suction hole 212, specifically, part of the air pump part 300 is located in the first connecting hole 231 and is connected to the air suction hole 212 through the first connecting hole 231, that is, when the vacuum seal 220 contacts the surface of the object to be transported, the air pump part 300 can evacuate air through the air suction hole 212, so that the internal air pressure of the vacuum seal 220 is lower than that of the outside, and the object to be transported is adsorbed on the vacuum seal 220 of the base part 200 by using the principle of atmospheric pressure. In addition, in addition to being arranged on the first receiving part 230 and the second receiving part 240, the second connecting part 250 can also be arranged on the substrate 210 of the base part 200.

[0058] like Figure 4 and Figure 6 As shown, the first connection part 130 includes a first connection hole 131, and the second connection part 250 includes a second connection hole 251 and a connection member (not shown). The connection member is used to connect the first connection hole 131 and the second connection hole 251. The connection member can be a screw or a bolt. The first connection hole 131 and the second connection hole 251 can be a threaded hole that matches the screw or the bolt. The cooperation of the screw, the bolt and the threaded hole can achieve the purpose of detachability. In addition, the first connection part 130 can also include the first connection hole 131 and a connection member (not shown). Correspondingly, the second connection part 250 includes a second connection hole. Similarly, the cooperation of the screw, the bolt and the threaded hole can achieve the purpose of detachability.

[0059] like Figure 7 As shown, the first connecting hole 231 is provided with a second step portion 232, and the second step portion 232 is provided with a first sealing ring 233. When the handle portion 100 and the base portion 200 are installed, the air inlet portion of the air pump portion 300 extends into the first connecting hole 231, passes through the fixing portion 310, and abuts against the first sealing ring to form a seal.

[0060] The air intake hole 212 is provided with a third step portion 213, and the third step portion 213 is provided with a filter screen 214. The air intake hole 212 is also provided with a fourth step portion 215, and the fourth step portion 215 is provided with a second sealing ring 216. When the first supporting member 230 and the substrate 210 are installed, part of the first supporting member 230 extends into the air intake hole 212 and abuts against the second sealing ring 216 to form a seal. At the same time, part of the first supporting member 230 also abuts against the filter screen 214.

[0061] like Figure 3 As shown, the base portion 200 is also provided with a pressure detection pipe 260, and the pressure detection pipe 260 is provided with a pressure detection sensor 261. Specifically, a through hole is provided in the overlapping part of the substrate 210 of the base portion 200 and the first receiving member 230, and the through hole connects the inside of the second sealing ring 216 and the outside. The pressure detection pipe 260 is installed in the through hole, and the first end of the pressure detection pipe 260 is inserted into the through hole and connected with the inside of the second sealing ring 216. The second end of the pressure detection pipe 260 is located in the accommodating portion 110 and is provided with a pressure detection sensor 261. The pressure detection sensor 261 can detect the air pressure inside the second sealing ring 216 through the pressure detection pipe 260.

[0062] like Figure 2 and Figure 7 As shown, the base portion 200 is also provided with an air inlet hole 270. When the air pump portion 300 draws air through the suction hole 212, the air extraction rate of the air pump portion 300 from the suction hole 212 should be greater than the air intake rate of the air inlet hole 270, and the air pressure inside the vacuum seal 220 will become smaller and smaller with the passage of time, so as to achieve the purpose of adsorbing the objects to be transported. In addition, since gas is constantly entering the air inlet hole 270, gas is constantly flowing through the air pump portion 300 during the process of drawing air. Therefore, the motor of the air pump portion 300 can be cooled with the help of gas to avoid the high temperature caused by zero airflow.

[0063] like Figure 3 , Figures 8 to 12 As shown, the electric suction cup further includes a control circuit 400 , which is printed on a circuit board located in the accommodating portion 110 , and the control circuit 400 includes a pressure sampling unit, a control unit and a motor control unit.

[0064] like Figure 8As shown, the pressure sampling unit is connected to the pressure detection sensor L1 (i.e., the pressure detection sensor 261), and the pressure sampling unit is used to collect pressure data detected by the pressure detection sensor L1; wherein, the model of the pressure detection sensor L1 can be XGZP-160, and the pressure sampling unit includes a capacitor C10, a resistor R25, a resistor R32, a capacitor C14, a capacitor C9, a capacitor C12, and a resistor R22, wherein the capacitor C10 is connected between the first pin of the pressure detection sensor L1 and the ground terminal GND, the first pin of the pressure detection sensor L1 is connected to the sixth pin, the resistor R25 is connected to the sixth pin of the pressure detection sensor L1, the second pin of the pressure detection sensor L1 is connected to the ground terminal GND, the resistor R32 is connected to the fourth pin of the pressure detection sensor L1, the capacitor C14 is connected between the fourth pin of the pressure detection sensor L1 and the ground terminal GND, the fifth pin of the pressure detection sensor L1 is connected to the +5V terminal through the resistor R22, the fifth pin of the pressure detection sensor L1 is also connected to the ground terminal GND through the capacitor C12, and the capacitor C9 is connected in parallel with the capacitor C12.

[0065] like Fig. 9 As shown, the control unit is connected to the pressure sampling unit, and the control unit generates a first control signal according to the received pressure data; specifically, the control unit is a chip U2, and the model of the chip U2 can be a single-chip microcomputer chip (51F003) with a C51 core. The control unit is connected to the resistor R25 through the twentieth pin, and is connected to the resistor R32 through the nineteenth pin. The control unit compares the pressure value F1 corresponding to the received pressure data with the preset pressure value F0. If the pressure value F1 is not less than the pressure value F0, it means that the internal air pressure of the vacuum seal 220 is not small enough, and the speed of the motor in the air pump part 300 is increased. If the pressure value F1 is less than the pressure value F0, it means that the internal air pressure of the vacuum seal 220 is small enough, and the speed of the motor in the air pump part 300 is reduced to achieve energy saving. In addition, for the control of the motor speed in the air pump part 300, it can also be automatically tracked and adjusted according to the detected pressure value F1. For example, a PID algorithm can be used for control. The PID algorithm formula is:

[0066]

[0067] Among them, u(t) is the output curve, which is the output of the control unit. The control unit controls the motor speed by controlling the motor control unit; Kp is the proportional coefficient, e(t) is the deviation curve, which is the curve of the deviation between the preset pressure value F0 and the detected pressure value F1 over time, Ti is the integration time, and Td is the integration time. Since the speed of the motor is linear, the speed is proportional to the pressure, so the corresponding speed corresponds to the corresponding pressure. Therefore, the u(t) curve here is to adjust the speed of the motor according to the feedback compensation adjustment to achieve the purpose of pressure balance. And this pressure value is proportional to the speed of the motor, so here we only consider the ratio of the preset pressure value F0 to the actual detected pressure value F1. The closer the pressure value is to the preset value, the slower the adjustment speed should be to prevent overshoot.
