Description

Technical Field

[0001] The present invention relates to the technical field of glove box glove quality detection, and in particular to a glove box glove integrity batch detection device and method. Background Art

[0002] In scientific research and industrial production, there are a large number of chemical experiments, material processing and performance testing work that require manual operation and cannot be carried out in ambient air. In order to ensure the scientific nature of the research and the safety of the operators, such operations are often carried out in glove boxes. In order to prevent a large amount of gas exchange between the box and the environment, causing damage to the box environment and leakage of harmful substances, the glove box is required to have very good airtightness. Gloves are an indispensable and important component of the glove box. When operators perform operations in the glove box, they will be directly affected by substances leaking through the gloves, so their airtightness is particularly important; at the same time, because the glove material is different from the metal and glass materials used in other parts of the glove box, its airtightness is relatively weak. Therefore, the airtightness of the gloves has an important influence on the performance of the glove box, and the integrity of the glove structure plays a decisive role in its airtightness.

[0003] At present, the main methods for glove integrity testing are the bubble method and the pressure drop method. The bubble method is to immerse the gloves inflated to positive pressure in water, and judge whether there is a leak point by the generation of bubbles. The pressure drop method is to inflate the inside of the gloves to positive pressure, and then judge whether there is a leak point by the change of the internal pressure of the gloves within a certain period of time. The bubble method is to immerse the gloves inflated to positive pressure in water, and judge whether there is a leak point by the generation of bubbles. During the bubble method detection process, since the inside of the gloves is full of gas, certain methods need to be used to deal with the buoyancy when immersing the gloves. At the same time, the observation time cannot be too short. It is necessary to carefully distinguish whether the bubbles that emerge are real leaks or false leaks. After the test is completed, the gloves need to be dried. The detection process is cumbersome and the detection efficiency is very low. Compared with the bubble method, the pressure drop method has a simple process and is easy to operate.

[0004] In the prior art, the pressure drop method detection device has the following problems: the part of the detection device used to fix the gloves and the part used to connect to the external air source are separately arranged, and they are assembled again during detection, which is not only inconvenient to operate, but also has assembly errors, affecting the reliability and stability of the detection device; the detection personnel are required to calculate the pressure change value according to the data of the pressure gauge or other detection equipment, and the detection needs to be carried out sequentially, which cannot meet the needs of large-scale glove detection and has low detection efficiency. Summary of the invention

[0005] In view of the shortcomings of the prior art, the present invention provides a device and method for batch testing of glove integrity in a glove box, which solves the technical problems of the existing pressure drop method testing scheme, such as the inconvenience in operation, the inability to synchronously and automatically obtain test results in large quantities, and the low detection efficiency.

[0006] The technical solution adopted by the present invention is as follows:

[0007] The present invention provides a glove box glove integrity batch detection device, the device comprises a main body and an inflation module;

[0008] The main body comprises a bracket, a fixing panel is provided on the bracket, a plurality of mounting holes are provided on the fixing panel, and each mounting hole is used for detachably connecting a glove receiving plate;

[0009] The structure of the glove receiving plate includes a plate body, and a connecting portion is provided on one side of the plate body, and the connecting portion is used to cooperate with the cuff area of ​​the glove to be tested, so as to be sealed and connected with the glove to be tested;

[0010] The disk body is provided with an air supply joint and a pressure detection joint;

[0011] The bracket is also provided with a plurality of pressure alarm modules, which are used to be respectively connected to the pressure detection joints of the glove receiving plates to detect whether the pressure inside each glove to be tested is within a preset range, and to make corresponding responses according to the detection results, indicating whether the detection results are qualified or unqualified;

[0012] The inflation module inflates air into the glove to be tested through the air supply connector.

[0013] Further technical solutions are:

[0014] The structure of the connecting portion includes a cylindrical surface, on which a positioning groove and at least one sealing groove are sequentially arranged along the axial direction; the positioning groove is used to accommodate the glove curling edge of the glove to be tested to achieve glove positioning; the sealing groove is used to cooperate with the binding piece to achieve sealing and fixation of the glove cuff area.

[0015] The binding member is an O-ring.

[0016] The pressure alarm module includes a pressure sensor, a controller and an alarm indicator light;

[0017] The pressure sensor is connected to the pressure detection joint via a connecting air pipe;

[0018] The controller is used to receive pressure sensor signals and convert them into pressure values, and to continuously collect pressure values, record pressure changes, compare the pressure changes with a preset pressure change range, and make a first light response through the alarm indicator light for the pressure changes within the preset pressure change range, and make a second light response through the alarm indicator light for the pressure changes outside the preset pressure change range.

[0019] The air supply joint adopts an airtight joint with a self-locking mode, which is connected when connected to the air supply pipe and automatically closed after disconnection.

[0020] The pressure detection joint is a normally open joint.

[0021] The mounting hole and the glove receiving plate are connected by threading, clamping or by a locking piece.

[0022] The number and positions of the plurality of pressure alarm modules correspond one to one with the number and positions of the mounting holes.

[0023] The present invention provides a detection method of the glove box glove integrity batch detection device, comprising the following steps:

[0024] According to the cuff diameter of the gloves to be tested in this batch, select the glove receiving plate with the model corresponding to the cuff diameter;

[0025] Fix each glove receiving plate to the fixed panel respectively, and connect the pressure detection connector of each glove receiving plate to the pressure alarm module accordingly;

[0026] Fixing a plurality of gloves to be tested on the glove receiving plates respectively, and sealing and fixing the gloves to be tested by using the connecting parts;

[0027] The inflation module is connected to the air supply connectors of each glove receiving plate in sequence through an air supply pipe, inflates the glove to be tested, makes the internal pressure of the glove reach the test requirement value, and stops inflation;

[0028] The gloves remain stationary, and within the set time range, each pressure alarm module continuously detects whether the pressure inside each glove to be tested is within the preset range, and makes a corresponding response based on the test results to indicate whether the glove integrity test is qualified.

[0029] As a further improvement of the above technical solution:

[0030] The pressure alarm module includes a pressure sensor, a controller and an alarm indicator light; the pressure sensor is connected to the pressure detection joint through a connecting air pipe;

[0031] During detection, when the glove is inflated and left to stand still, the controller receives the pressure sensor signal within a set time range and converts it into a pressure value, continuously collects pressure values ​​and records pressure changes, and compares the pressure changes with a preset pressure change range; if the pressure change is within the preset pressure change range, a first light response is made through the alarm indicator light; if the pressure change exceeds the preset pressure change range, a second light response is made through the alarm indicator light.

[0033] The present invention realizes the automatic integrity detection of multiple gloves in a batch based on the pressure drop method, and can obtain the detection results of all gloves simultaneously, which is easy to operate and has high detection result accuracy. It has the following advantages:

[0034] Compared with the conventional method of judging integrity by calculating the pressure change value by a person, the present invention uses a pressure alarm module to automatically judge the integrity of the gloves, and directly obtains the conclusion of whether the test is qualified based on the response sent by the pressure alarm module.

[0035] The glove receiving tray of the present invention corresponds to the pressure alarm module one by one, and the detection results of all gloves can be obtained synchronously. The number and position of the glove receiving tray installation positions can be set according to actual conditions to achieve batch detection. In addition, the operation is simple, and only one staff member is required to complete all operations, which greatly improves the detection efficiency of glove integrity in the production process and reduces the detection cost.

[0036] The glove receiving plate of the present invention is installed in a modular manner with the fixed panel. On the one hand, by replacing the glove receiving plate, it can be suitable for the detection of gloves with various cuff diameters. On the other hand, by combining glove receiving plates of various sizes and types, gloves of different sizes can be detected at the same time.

[0037] The glove receiving tray structure of the present invention is a combination of a tray body and a connecting part, that is, the part for fixing the gloves and the part for connecting to the external air source are integrated into one, and the structural design is reasonable and ingenious. The gloves can be positioned by the connecting part, and the cuff area can be fixed and sealed in cooperation with the binding parts, which not only ensures the sealing performance, but also greatly improves the convenience of assembly and disassembly of the gloves. On the one hand, the tray body ensures the compatibility of the detachable connection with the fixed panel, that is, the tray bodies of different glove receiving trays can be the same, and only the size of the connecting part can be set to be different; on the other hand, two connectors are set on the tray body, which is convenient for connection with the pressure alarm module and the inflation module, and there is no problem of reassembly, which improves reliability.

[0073] Example 2

[0074] This embodiment provides a detection method of the glove box glove integrity batch detection device of embodiment 1, comprising the following steps:

[0075] According to the cuff diameter of the gloves to be tested in this batch, a glove receiving plate 120 with a model corresponding to the cuff diameter is selected;

[0076] Fix each glove receiving plate 120 to the fixed panel 130 respectively, and connect the pressure detection connector 123 of each glove receiving plate 120 to the pressure alarm module 140 accordingly;
