Description

Technical Field

[0001] This utility model relates to glove testing equipment, specifically to a glove airtightness testing device. Background Technology

[0002] After gloves are manufactured, they typically undergo an airtightness test to check for damage. Traditional airtightness testing involves inflating the gloves and then visually inspecting them for leaks. This requires manual inspection of each glove, which is physically demanding for workers. Furthermore, small leaks may be difficult to detect, leading to low-quality testing, false positives, and a poor user experience. Utility Model Content

[0003] In view of the shortcomings of the prior art, the technical problem to be solved by this utility model is to provide a glove airtightness detection device for solving the above-mentioned problems.

[0004] Therefore, this utility model is implemented using the following solution:

[0005] A glove airtightness testing device includes an inflation head, on which a glove can be fitted. A positioning and clamping component is provided corresponding to the inflation head and connected to a clamping drive assembly. The positioning and clamping component can seal the open end of the glove against the inflation head. The inflation head has an air outlet to inflate the fitted glove. The air outlet is connected to a first air chamber inside the inflation head. The inflation head has an air inlet and an air return port connected to the first air chamber. A shut-off valve is provided corresponding to the air inlet, and a pressure sensor is provided corresponding to the air return port. The pressure sensor can feed back the air pressure at the air return port to a controller. The controller analyzes the airtightness of the glove based on the air pressure information fed back over a certain period of time.

[0006] The top of the inflation head has a first pressing slope, the middle of the positioning pressing member has a clearance groove for the inflation head to pass through, and the positioning pressing member has a second pressing slope that can cooperate with the first pressing slope to seal and press the opening end of the glove.

[0007] The clamping drive assembly includes a first cylinder, the piston rod of the first cylinder is connected to the lifting frame, and the positioning clamping component is disposed on the lifting frame.

[0008] The positioning and clamping component is provided with a second air chamber, and the positioning and clamping component is provided with an air inlet communicating with the second air chamber. The top surface of the positioning and clamping component is provided with an air blowing hole communicating with the second air chamber.

[0009] The top of the inflation head is also equipped with a searchlight.

[0010] The above-mentioned glove airtightness detection device has a simple structure and reasonable design. By cooperating with the inflation head and the positioning and clamping parts, the glove can be positioned and clamped, which facilitates the inflation of the glove. Through the innovative design of the return air port and air pressure sensor structure, the controller can analyze whether there is an air leak based on the air pressure data of the return air port. This replaces the traditional manual observation method, greatly reduces the labor intensity of workers, and improves the efficiency and quality of detection, thus providing a better user experience. Attached Figure Description

[0011] The present invention includes the following figures:

[0012] Figure 1 This is a schematic diagram of the structure of this utility model;

[0013] Figure 2 for Figure 1 Another perspective. Detailed Implementation

[0014] As shown in the figure, this utility model discloses a glove airtightness testing device, including an inflation head 4. A glove can be fitted onto the inflation head 4. A positioning and clamping component 8 is provided corresponding to the inflation head 4, and the positioning and clamping component 8 is connected to a clamping drive assembly. The positioning and clamping component 8 can seal the open end of the glove onto the inflation head 4. The inflation head 4 is provided with an air outlet 1 to inflate the fitted glove. The air outlet 1 communicates with a first air chamber inside the inflation head 4. The inflation head 4 has an air inlet 12 and an air return port 13 communicating with the first air chamber. A shut-off valve is provided corresponding to the air inlet 12. The shut-off valve can be a solenoid valve structure. A pressure sensor is provided corresponding to the air return port 13. The pressure sensor can feed back the air pressure of the air return port 13 to the controller. The controller analyzes the airtightness of the glove based on the air pressure information fed back over a certain period of time. The air inlet is connected to an air pump through an air pipe.

[0015] Furthermore, the top of the inflation head 4 has a first pressing slope 3, the middle of the positioning pressing member 8 has a clearance groove 6 for the inflation head 4 to pass through, and the positioning pressing member 8 has a second pressing slope 5 that can cooperate with the first pressing slope 3 to seal and press the opening end of the glove. With the above structure, by controlling the movement of the positioning pressing member 8, the first and second pressing slopes can be used to press the opening end of the glove to achieve the positioning and sealing of the glove.

[0016] Furthermore, the clamping drive assembly includes a first cylinder 11, the piston rod of which is connected to the lifting frame 10, and the positioning clamping component 8 is mounted on the lifting frame 10. With this structure, by controlling the first cylinder 11 to move the lifting frame 10, the positioning clamping component 8 can be actuated. Of course, besides using a cylinder, common linear drive mechanisms such as linear motors and rack and pinion structures can also be used to drive the movement of the lifting frame 10.

[0017] Furthermore, a second air chamber is provided within the positioning and clamping component 8, and an air inlet 9 communicating with the second air chamber is provided on the positioning and clamping component 8. An air blowing hole 7 communicating with the second air chamber is arranged around the top surface of the positioning and clamping component 8. With this structure, when the glove is damaged, air can be blown through the air blowing hole 7 to lift the fallen glove into a vertical position, thus facilitating the subsequent gripping robot arm to grasp and transfer the glove.

[0018] Furthermore, a spotlight 2 is also provided on the top of the inflation head 4. This allows for easy observation of whether there are any other defects in the gloves.

[0019] The working principle of this utility model is as follows: First, the glove to be tested is placed on the inflation head 4. Then, the positioning and clamping part 8 is controlled to press the open end of the glove onto the inflation head 4, thus sealing the glove. Next, a certain amount of gas is injected into the inflation head 4 through the air inlet 12 and into the glove through the air outlet 1, causing the glove to expand. Then, the on / off valve is closed, and the glove is kept in an inflated state for a certain period of time, such as 10 seconds. During this process, the air pressure sensor at the air return port 13 will continuously feed back the detected air pressure to the controller. The controller will analyze whether there is a pressure difference between the air pressure fed back by the air return port 13 at different time points during this process. If there is no pressure difference, it means that the glove has not leaked and is a qualified product. If there is a pressure difference, it means that the glove has leaked and is a defective product.

[0020] In addition, during actual use, due to factors such as equipment assembly precision and testing precision, there may be certain testing errors. A pressure difference range can be set in the controller according to the actual testing and usage. If the controller analyzes the air pressure difference fed back by the air return port 13 at the time points before and after the process and it is within the set pressure difference range, it means that the gloves are qualified products. If the controller analyzes the air pressure difference fed back by the air return port 13 at the time points before and after the process and it is greater than the set pressure difference range, it means that the gloves have air leakage and are unqualified products.
