Description

Electric suction cup TECHNICAL FIELD

[0001] The present application relates to the technical field of suction cups, in particular to an electric suction cup. BACKGROUND

[0002] A suction cup is an intermediate object that fixes two objects together by atmospheric pressure. For example, in the building decoration industry, when flat materials such as ceramic tiles, door and window glasses need to be transported, manual transportation is often used. Before transportation, workers not only need to wear protective equipment, but also need to separate the flat materials stacked together. These flat materials not only adhere to each other and are difficult to separate, but also have smooth surfaces and are easy to slip from the hands and cause damage, resulting in an increase in the rate of defective products. Therefore, suction cups are often used as auxiliary tools to transport flat materials during transportation. It is a very good way to use suction cups to hold ceramic tiles, door and window glasses, and then hold the suction cup for transportation.

[0003] However, in the prior art, the base and the handle of the suction cup cannot be disassembled, so when one of the base and the handle is damaged, the entire suction cup must be replaced.

In addition, the second connecting part 250 can also be arranged on the base plate 210 of the base part 200 in addition to being arranged on the first receiving member 230 and the second receiving member 240.

[0059] As shown in FIG. 4 and FIG. 6, the first connecting part 130 comprises the first connecting hole 131, the second connecting part 250 comprises the second connecting hole 251 and the connecting member (not shown), the connecting member is used to connect the first connecting hole 131 and the second connecting hole 251, the connecting member can be a screw or a bolt, the first connecting hole 131 and the second connecting hole 251 can be threaded holes matched with the screw or the bolt, and the screw, the bolt and the threaded holes are cooperated to achieve the purpose of detachability.

[0060] As shown in Fig. 7, the first communication 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 communication hole 231 and penetrates the fixing portion 310 to abut against the first sealing ring to form a seal.

Specifically, a through hole is arranged in the overlapping portion of the base plate 210 of the base portion 200 and the first receiving member 230, and the through hole communicates the inside of the second sealing ring 216 with the outside.

[0063] As shown in Fig. 2 and Fig. 7, the base portion 200 is further provided with an air inlet hole 270. When the air pump portion 300 is pumping air through the air suction hole 212, the pumping rate of the air pump portion 300 from the air suction hole 212 should be greater than the air inlet rate of the air inlet hole 270, and the air pressure in the inside of the vacuum sealing member 220 will become smaller and smaller over time, so as to achieve the purpose of adsorbing the objects to be carried. In addition, since the air inlet hole 270 is always filled with gas, there is always gas flowing through the air pump portion 300 during the pumping process, so that the motor of the air pump portion 300 can be cooled by the gas, thereby avoiding high temperature caused by zero gas flow.

[0064] As shown in Fig. 3, Fig. 8 to Fig. 12, the electric suction cup further comprises a control circuit 400, and the control circuit 400 is printed on a circuit board. The circuit board is located in the containing portion 110, and the control circuit 400 comprises a pressure sampling unit, a control unit and a motor control unit.

In addition, the control of the rotating speed of the motor in the air pump part 300 can also be automatically tracked and adjusted according to the detected pressure value F1, for example, a PID algorithm can be used for control, and the formula of the PID algorithm is:

[0067] Wherein, u(t) is the output curve, as the output of the control unit, the control unit controls the motor control unit to control the motor speed; Kp is the proportional coefficient, e(t) is the deviation curve, the deviation between the preset pressure value F0 and the detected pressure value F1 changes with time, Ti is the integral time, and Td is the integral 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, so the u(t) curve here is to adjust the speed of the motor according to the feedback compensation to achieve the purpose of pressure balance. And this pressure value is proportional to the speed of the motor, so here only consider the preset pressure value F0 and the actual detected pressure value F1 of a proportional calculation pressure value is closer to the preset value, the adjustment speed should be slower, to prevent overshoot.
