Description

Technical Field

[0001] This utility model relates to the field of airtightness testing, and more specifically, to a box airtightness testing device. Background Technology

[0002] In industrial production, the airtightness of enclosures is a key indicator for ensuring their quality and reliability, and they are widely used in many industries such as aerospace, automotive manufacturing, and electronic equipment. With the continuous development of industrial automation and intelligence, traditional methods for testing the airtightness of enclosures have gradually revealed many problems that make them unable to meet the demands of modern production.

[0003] During the testing process, insufficient clamping force and uneven pressure in different parts are prominent problems with traditional testing equipment. The top of the chamber may be uneven or concave, making it impossible to apply stable and sufficient pressure to the chamber, which can easily lead to air leakage during airtightness testing and affect the accuracy of the test results.

[0004] Furthermore, in the traditional process of testing the airtightness of enclosures, the loading and unloading of products relies on manual operation, requiring two people to lift and lower the product for testing. This manual operation method not only consumes a lot of manpower but is also inefficient and cannot adapt to the pace of large-scale, high-efficiency modern production. In today's context of continuously rising labor costs, it seriously increases the production costs of enterprises. Utility Model Content

[0023] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical applications of the present invention, and to enable those skilled in the art to understand the present invention and design various embodiments with various modifications suitable for a particular purpose.

[0024] like Figures 1-4 As shown, the present invention provides a box airtightness testing device, including a handling robot 1, a mounting bracket, a translation mechanism 21 mounted on the mounting bracket, a testing support 11 mounted on the translation mechanism 21, a pressing mechanism 14 located above the translation mechanism 21, and an airtightness testing mechanism 13 connected to the testing support 11, with the box 12 placed on the testing support 11.

[0025] In the above scheme, the handling robot 1 can transport the box 12 to the detection support 11. The translation mechanism 21 drives the detection support 11 to move horizontally, realizing the positioning switch of the box 12 between the material handling area and the detection area. The pressing mechanism 14 can press the top of the box 12 to seal the connection between the box 12 and the detection support 11, preventing external gas from entering and interfering with the detection.

[0026] The material support mechanism is also provided on one side of the handling robot 1. The material support mechanism includes a support base 8 and L-shaped limiting blocks 9 set at the four corners of the support base 8. Each limiting block is equipped with a proximity switch 10. The L-shaped limiting blocks physically position the box 12 (restricting movement along the X and Y axes). The proximity switches 10 detect whether the box 12 is in position and send a signal to the control system to trigger the action of the handling robot 1. The support base 8 provides stable support to ensure that the box 12 is accurately positioned before handling.

[0027] The handling robot 1 includes a robotic arm 2 and a handling frame 3 disposed at the end of the robotic arm 2. Suction cup structures 4 and anti-detachment mechanisms are evenly distributed on the handling frame 3. The anti-detachment mechanism includes an anti-detachment gripper 6 and a rotary drive cylinder 5 for driving the anti-detachment gripper 6 to rotate. The anti-detachment gripper 6 includes at least three spaced-apart gripping rods 7, and each gripping rod 7 has a buffer pad inside.

[0028] The suction cup structure 4 uses a vacuum pump to generate negative pressure to adsorb onto the upper surface of the box 12, and the evenly distributed suction cups ensure balanced force. The rotary drive cylinder 5 drives the anti-detachment gripper 6 to rotate, and at least three gripping rods 7 (with built-in buffer pads) clamp the side wall of the box 12 from the side, forming a double fixation of "adsorption + clamping" to prevent the box 12 from falling off during transportation. The robotic arm 2 completes the transportation action from the material support mechanism to the detection support 11 according to the control system instructions and a preset trajectory. The buffer pad is made of silicone material, which can adapt to different side curvatures of the box 12.

[0029] The detection support 11 has a groove, and the housing 12 is inverted inside the groove, forming a sealed space between the cavity of the housing 12 and the groove. The airtightness detection mechanism 13 is connected to the groove. When the housing 12 is inverted into the groove, a sealed space is formed through precision machining or sealing strips, providing the basic conditions for airtightness detection. The airtightness detection mechanism 13 fills the sealed space with compressed air through an air pump, and a pressure sensor monitors the air pressure change in real time. After reaching a specified air pressure value, the pressure is maintained (e.g., for 2 minutes), and the airtightness is determined based on the leakage amount. The data is synchronized to the control system.

[0030] The pressing mechanism 14 includes a pressing drive and a pressing assembly connected to the pressing drive. The pressing assembly includes several pressing parts that are movably connected. The pressing drive includes several pressing drive cylinders 15, each of which is connected to one pressing part. Two adjacent pressing parts are connected by a slider 16 and a groove 17. The bottom of each pressing part includes a pressing block 18 and a rubber pad 19 disposed at the bottom of the pressing block 18.

[0031] Each pressing part is driven independently by the downward driving cylinder 15. When the detection support 11 moves to the position directly below the pressing mechanism 14, the cylinder pushes the pressing part down. Adjacent pressing parts slide relative to each other through the structure of slider 16 and slide groove 17, adapting to the concave and convex shape of the top of the box 12, so that the rubber pressure pad 19 is evenly attached to the surface of the box 12. The elastic deformation of the rubber pressure pad 19 fills the gaps, and with the constant pressure of the cylinder, it achieves flexible pressing, avoids deformation of the box 12 and ensures the sealing effect.

[0032] The safety light curtain 20 forms a protective light curtain by emitting infrared beams. When a person blocks the beam, the receiver sends a signal to the control system to immediately stop the moving parts such as the handling robot 1 and the pressing mechanism 14, ensuring the safety of the operator.

[0033] The control system coordinates the actions of each mechanism through a PLC or industrial computer. The process is as follows: "material arrival detection → robot handling → translation and positioning → pressing and clamping → airtightness detection → result judgment → robot unloading". Each link achieves closed-loop control through sensor signals (such as proximity switches and pressure sensors).

[0034] In this solution, the handling robot 1 achieves fully automated loading and unloading, replacing manual operation, reducing labor costs and improving efficiency. A double-fixed anti-detachment mechanism ensures safe handling. The pressing mechanism 14, through an independent cylinder and a flexible pressing part, adapts to the surface of the housing 12, uniformly pressing to prevent air leakage and ensuring detection accuracy. The overall equipment has a high degree of automation, is adaptable to multiple specifications of housings 12, improves production efficiency and product qualification rate, and conforms to the trend of industrial intelligence.
