[0002] In order to ensure the operating efficiency and safety of equipment, various fields have increasingly higher requirements for the air tightness of equipment. Therefore, the equipment is generally tested for air tightness before it is put into use. For example, before a car's battery box is put into use, the air tightness of the battery box needs to be tested.

[0003] The existing air tightness detection device usually immerses the product to be tested in water and judges whether the air tightness of the product is good by whether bubbles are generated. However, the product needs to be dried after the test is completed, which increases the cost and causes low work efficiency and wastes some unnecessary costs.

[0004] Therefore, an airtightness detection device combined with intelligent vision is proposed to solve the above problems. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides an airtightness detection device combined with intelligent vision, which aims to improve the problem that the required test product needs to be dried after the airtightness test in water and needs to be manually collected after the test is completed.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solution: an airtightness detection device combined with intelligent vision, comprising a workbench, a detection box fixedly connected to the top of the workbench, two cylinders fixedly connected to the top of the workbench, the output end of the cylinder fixedly connected to the base plate, the bottom of the base plate fixedly connected to a sealing cover plate, the top of the base plate fixedly connected to an air pump, the output end of the air pump fixedly connected to an air pipe, an air pressure sensor fixedly connected to the inside of the detection box, a fixed plate fixedly connected to the top of the workbench, and a collection component for automatically collecting products is provided inside the detection box.

[0007] As a further description of the above technical solution:

[0008] The collecting assembly includes a motor, which is fixedly connected to one side of the fixed plate, a turntable is fixedly connected to the output end of the fixed plate, an eccentric shaft is fixedly connected to one side of the turntable, a connecting shaft is rotatably connected to the outer side of the eccentric shaft, an annular frame is fixedly connected to the end of the connecting shaft away from the eccentric shaft, a circular column is fixedly connected to the inside of the annular frame, a fixing ring is fixedly connected to one side of the fixed plate, and a rubber plate is fixedly connected to the end of the circular column away from the annular frame.

[0009] As a further description of the above technical solution:

[0010] The outer side of the trachea is inserted into the interior of the sealing cover plate, and the outer side of the sealing cover plate abuts against the top of the detection box.

[0011] As a further description of the above technical solution:

[0012] The outer side of the workbench is fixedly connected with a visual host, and the bottom of the workbench is fixedly connected with an arc plate.

[0013] As a further description of the above technical solution:

[0014] A long groove is provided on the outside of the detection box, and a collection box is provided at the bottom of the workbench.

[0015] As a further description of the above technical solution:

[0017] As a further description of the above technical solution:

[0018] A plurality of blocks are fixedly connected inside the detection box, and a sealing ring is fixedly connected to the top of the rubber plate.

[0019] As a further description of the above technical solution:

[0020] The rubber plate and the stopper abut against each other.

[0021] The utility model has the following beneficial effects:

[0022] 1. In the present invention, the product to be tested is first placed in the test box, and then the cylinder is started, whereupon the bottom plate begins to descend until the sealing cover plate under the bottom plate contacts the inner wall of the test box, so that the interior of the test box is in a sealed state. The air pump is then started, and the air pipe begins to inject a certain amount of gas into the interior of the test box. The data is transmitted to the visual host through the air pressure sensor. When the pressure remains unchanged, the product has good air tightness. If the product enters the gas, the air pressure value will change, indicating that the product has poor air tightness. This effectively avoids the problem of testing the product in water and then needing to dry the product, effectively improving work efficiency and reducing waste of manpower and material resources.

[0023] 2. In the present invention, when the inspection is completed, the motor is started, and the motor drives the turntable to rotate. Subsequently, under the joint action of the eccentric shaft, the connecting shaft and the annular frame, the circular column will slide back and forth inside the fixed ring. Subsequently, the rubber plate connected to the circular column will be pulled out, so that the inspected product can slide from the curved plate into the collection box, avoiding the need to manually remove it after the inspection is completed, and effectively improving work efficiency.
