Description

Technical Field

[0001] The utility model relates to the field of air pump part production, in particular to an air pump diaphragm airtightness detection device. Background Art

[0002] As shown in the related art air pump diaphragm Figure 1 A head is provided on the top of the outer end face of the air pump diaphragm. The air pump diaphragm is an important part of the diaphragm air pump. The working principle of the diaphragm air pump is to inhale and discharge gas by relying on the reciprocating motion of the diaphragm in the pump body. Therefore, the quality of the airtight performance of the air pump diaphragm has a great impact on the use of the diaphragm air pump. Therefore, it is necessary to detect the airtightness of the air pump diaphragm before leaving the factory.

[0003] A common airtightness detection method is to place the air pump diaphragm to be tested in a water tank, and then inflate and pressurize the cavity of the air pump diaphragm. At this time, observe the bubble situation formed between the outer surface of the air pump diaphragm and the water to judge whether there is air leakage in the air pump diaphragm. However, after the detection, it is necessary to take out the air pump diaphragm in the water tank, and it is necessary to dry or bake the residual water on the air pump diaphragm. The drying or baking steps will be time-consuming and laborious, reduce the processing efficiency of the entire air pump diaphragm, and increase its processing cost. Summary of the Utility Model

[0004] The present application provides an air pump diaphragm airtightness detection device, which has the effect of accelerating the airtightness detection rate of the air pump diaphragm.

[0005] The technical solution adopted by the air pump diaphragm airtightness detection device provided by the present application is as follows:

The detection component includes a placement plate, a support frame, a plurality of sealing blocks and a plurality of lifting cylinders. The placement plate is arranged on the detection table. A plurality of placement cavities are opened on the placement plate, and the placement cavities are used for placing air pump diaphragms; the plurality of lifting cylinders are arranged directly above the placement plate through the support frame and face the placement plate; a plurality of the sealing blocks are arranged one-to-one on the telescopic rods of the lifting cylinders and correspond up and down to the plurality of placement cavities; an air flow channel is arranged in the sealing block; one end of the air flow channel extends to the lower end of the sealing block, and the other end is connected to a gas source; a pressure sensor for detecting the air pressure in the air flow channel is also arranged on the sealing block.

[0007] Through the above technical solution, during the detection work, the lifting cylinder drives the sealing block to abut against the placing plate, and seals with the air pump diaphragm to form a detection chamber. Then, the detection chamber is inflated through the air source and the air flow channel. At the same time, the air pressure sensor is used to monitor the air pressure in the detection chamber and judge whether the air pump diaphragm leaks air; this avoids the situation that the water detection method requires later drying or baking; at the same time, the setting of multiple sealing blocks, multiple lifting cylinders and multiple placing chambers can detect multiple air pump diaphragms at one time, and speeds up the rate of airtightness detection of the air pump diaphragms.

[0008] Preferably, the multiple placing chambers are distributed in two rows and arranged front and back; a turntable is installed on the detection table, and the placing plate is installed on the turntable; a driving mechanism for driving the turntable to rotate a preset angle is also installed on the detection table, so that the two rows of placing chambers can be intermittently placed directly below the sealing block.

The operator takes out the air pump diaphragm that has been detected at the other end and puts in a new air pump diaphragm to be detected, which speeds up the work efficiency.

[0010] Preferably, it further includes a lifting table, a movable cylinder and several pneumatic scissors. The several pneumatic scissors are installed on the lifting table and correspond to the placing chambers one by one up and down; the movable cylinder is installed on the detection table and is used to drive the lifting table to lift and lower.

[0011] Through the above technical solution, when the air pressure sensor monitors that the air pressure is lower than the preset value, the movable cylinder drives the lifting table to lift, aligning the cutting opening of the pneumatic scissors with the air pump diaphragm, and then cutting off the head at the bottom of the air pump diaphragm with a detected air pressure lower than the preset value to remind the operator that the air pump diaphragm is a leaking part.

[0012] Preferably, a lamp holder is installed on the detection table, and several spotlights are installed on the lamp holder. The several spotlights correspond to the placing chambers in the front row one by one up and down.

[0013] Through the above technical solution, when the head of an air pump diaphragm is cut, the corresponding spotlight is turned on after the leaking part rotates, illuminating to remind the operator that the air pump diaphragm is a leaking part, so as to further remind the operator that the air pump diaphragm is a leaking part and play a role in preventing mistakes.

[0014] Preferably, an infrared detection device is also installed on the detection table and on one side of the placing plate.

[0015] Through the above technical solution, the infrared detection device is used to detect whether an operator reaches his hand or other objects over the placing board; if such a situation is detected, the infrared detection device will immediately send a signal to control the device to stop, so as to avoid affecting the detection and harming the operator.

[0016] Preferably, a plurality of display panels are further installed on the lamp holder, and the plurality of display panels are located on one side of the spotlight.

[0017] Through the above technical solution, the display panel is used to display the air pressure measured by the air pressure sensor in real time; thus, when the device is damaged, the operator can timely understand the situation through the display panel, reducing the complexity of maintenance.

[0018] The technical effects of the present utility model are mainly reflected in the following aspects:
