[0020] The utility model provides an airtightness measurement device, which includes an operation table 101 and an optocoupler induction type air extraction detection component. The optocoupler induction type air extraction detection component includes a workbench 104, an air extraction table 113, a clamping groove 114, a positioning rod 115, an optocoupler identifier 116, a display screen 102, control buttons 103, positioning columns 112, a support plate 105, a top plate 106, a cylinder 107, a push column 108, an upper push plate 109, a positioning plate 110 and a sealing plate 111. Through the foregoing solution, the problem that most of the existing devices cannot ensure the high-precision fitting of the mobile phone with the mold during detection and cannot achieve automation, which may cause the hands of the staff to be squeezed during feeding, and there are certain safety hazards, is solved. It can be understood that in the foregoing solution, when performing airtightness detection on the mobile phone, the staff will place the mobile phone in the clamping groove 114 in the air extraction table 113, and then press the control button 103. The optocoupler identifier 116 will start to work to detect whether there is a mobile phone in the clamping groove 114. When the detection is completed, the cylinder 107 will be started, and the cylinder 107 will apply a downward thrust to the push column 108. Thus, the upper push plate 109 will move downward. At the same time, the moving position of the upper push plate 109 will be limited by the positioning column 112 to prevent deviation. At the same time, after the upper push plate 109 reaches the specified position, the positioning plate 110 and the positioning rod 115 will perform positioning operations with each other to prevent small deviations. The sealing plate 111 will effectively fill the gap between the mobile phone and the clamping groove 114. Thus, it will effectively ensure that a closed space is formed between the clamping groove 114 and the sealing plate 111 during air extraction. Then the air extraction table 113 will start to extract air and extract the air in the clamping groove 114. When the detection passes, the display screen 102 will display "OK", and when the detection fails, the display screen 102 will display "NG". Thus, it is convenient for the staff to judge the airtightness of the mobile phone. Thus, the problem that most of the existing devices cannot ensure the high-precision fitting of the mobile phone with the mold during detection and cannot achieve automation, which may cause the hands of the staff to be squeezed during feeding, and there are certain safety hazards, is effectively solved.

[0021] For this specific embodiment, the workbench 104 is fixedly connected to the operating table 101 and is located on one side above the operating table 101. The air extraction table 113 is detachably connected to the workbench 104 and is located at the center above the workbench 104. The clamping groove 114 is fixedly connected to the air extraction table 113 and is located at the center inside the air extraction table 113. The positioning rod 115 is fixedly connected to the air extraction table 113 and is located above the air extraction table 113, and the positioning rod 115 is arranged on one side of the clamping groove 114. The optocoupler identifier 116 is fixedly connected to the air extraction table 113 and is located above the air extraction table 113, and the optocoupler identifier 116 is arranged on one side of the positioning rod 115. The workbench 104 and the air extraction table 113 will be the places for air extraction to detect the airtightness of the mobile phone, and the clamping groove 114 is the space for placing the mobile phone. The positioning rod 115 will cooperate with the positioning plate 110 to prevent small deviations during the detection process, thus affecting the detection result. The optocoupler identifier 116 will effectively detect the inside of the clamping groove 114, thereby preventing the cylinder 107 from starting without the mobile phone being placed, effectively protecting the safety of the staff.

[0022] Among them, the display screen 102 is fixedly connected to the operating table 101 and is located on one side of the operating table 101. The control button 103 is detachably connected to the operating table 101 and is located above the operating table 101, and the control button 103 is arranged on one side of the workbench 104. When the detection is passed, the display screen 102 will display "OK". When the detection fails, the display screen 102 will display "NG", thus facilitating the staff to judge the airtightness of the mobile phone. The control button 103 is a control-type auxiliary component for controlling the overall start.

[0023] Secondly, the positioning column 112 is fixedly connected to the workbench 104 and is located above the workbench 104, and the positioning column 112 is arranged on one side of the air extraction table 113. The support plate 105 is fixedly connected to the workbench 104 and is located on one side of the workbench 104, and the support plate 105 is arranged on one side of the positioning column 112. The top plate 106 is detachably connected to the support plate 105 and is located above the support plate 105, and the top plate 106 is arranged above the air extraction table 113. The positioning column 112 will limit the movement track of the upper push plate 109 when moving downward, and the support plate 105 will cooperate with the top plate 106 to effectively place the cylinder 107.

[0024] Meanwhile, the cylinder 107 is fixedly connected to the top plate 106 and is located at the center above the top plate 106. One end of the push column 108 passes through the top plate 106 and is detachably connected to the cylinder 107 and is located at the output end of the cylinder 107. And the push column 108 is arranged below the top plate 106. The upper push plate 109 is detachably connected to the push column 108 and is located below the push column 108. And the push column 108 is arranged on the outer surface of the positioning column 112. The cylinder 107 is a functional structural component that provides the necessary power for the push column 108. And the push column 108 is a component that pushes the upper push plate 109. The upper push plate 109 is a structural component that connects and pushes the positioning plate 110 and the sealing plate 111.

[0025] In addition, the positioning plate 110 is fixedly connected to the upper push plate 109 and is located at the center below the upper push plate 109. And the positioning plate 110 is arranged above the positioning rod 115. The sealing plate 111 is detachably connected to the positioning plate 110 and is located below the positioning plate 110. And the sealing plate 111 is arranged above the clamping groove 114. The positioning plate 110 will cooperate with the positioning rod 115 to prevent small errors from occurring, which may lead to inaccurate detection results. And the sealing plate 111 will cooperate with the clamping groove 114 to form a closed space for the air extraction table 113 to perform airtightness detection on the mobile phone.

[0026] When using the present utility model to perform airtightness detection on a mobile phone, a staff member will place the mobile phone in the clamping groove 114 in the air extraction table 113, and then press the control button 103. The optocoupler identifier 116 will start working to detect whether there is a mobile phone in the clamping groove 114. When the detection is completed, the cylinder 107 will be activated, and the cylinder 107 will apply a downward thrust to the push column 108. Thus, the upper push plate 109 will move downward. At the same time, the movement position of the upper push plate 109 will be limited by the positioning column 112 to prevent deviation. At the same time, after the upper push plate 109 reaches the designated position, the positioning plate 110 and the positioning rod 115 will perform positioning operations on each other to prevent fine deviation. And the sealing plate 111 will effectively fill the gap between the mobile phone and the clamping groove 114. Thus, it will effectively ensure that a closed space is formed between the clamping groove 114 and the sealing plate 111 during air extraction. Then the air extraction table 113 will start to extract air and extract the air in the clamping groove 114. When the detection passes, the display screen 102 will display "OK", and when the detection fails, the display screen 102 will display "NG". Thus, it is convenient for the staff to judge the airtightness of the mobile phone. Thus, it effectively solves the problem that most existing devices cannot ensure the high-precision fit between the mobile phone and the mold during detection, and cannot achieve automation, and may cause the staff's hands to be squeezed during feeding, posing a certain safety hazard.

[0027] The above-disclosed is only a preferred embodiment of the present utility model. Of course, it cannot be used to limit the scope of the rights of the present utility model.
