Meanwhile, the terms such as "upper", "lower", "left", "right", "middle" and "one" used in this specification are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.
[0044] Please see Figures 1 to 4 As shown, this utility model provides an airtightness testing device, comprising:
[0045] Frame 1, on which an air inlet pipe 302 is provided;
[0046] Conveying assembly 2, which is mounted on the frame 1;
[0047] The detection component 3 includes a detection bracket 301 and a plurality of sealing plugs 303 disposed on the detection bracket 301. The detection bracket 301 is disposed on the conveying component 2, and a detection area is formed between the detection bracket 301 and the conveying component 2. All the sealing plugs 303 are movably mounted on the detection bracket 301.
[0048] The lifting assembly 4 includes a support plate 401, a lifting unit 402, and a pressure sensor 403. The support plate 401 is disposed below the detection area. The lifting unit 402 is mounted on the frame 1. The support plate 401 is mounted on the movable end of the lifting unit 402. The pressure sensor 403 is mounted on the support plate 401. The lifting unit 402 is used to drive the support plate 401 to rise or fall.
[0049] A leak detector 10 is installed on the frame 1. The leak detector 10 is connected to the pressure sensor 403 or the air inlet pipe 302. The purpose of setting up the leak detector 10 is to accurately detect gas leakage inside or outside the object being tested by measuring parameters such as gas pressure, flow rate or pressure difference. It can accurately detect and locate the leak point, so that the manufacturing enterprise can repair and improve it in time, thereby improving the sealing performance of the product.
[0050] It should also be noted that during use, when the conveying component 2 is moving the motor controller, when the motor controller is conveyed to the detection area, the lifting unit 402 drives the support plate 401 to rise, which in turn drives the motor controller located on the support plate 401 to move upward. During the upward movement, the air inlet pipe 302 and the sealing plug 303 block the opening on the motor controller, and the pressure sensor 403 at the bottom also blocks the opening of the motor controller. After the sealing is completed, air is introduced into the motor controller through the air inlet pipe 302, and the pressure change is observed by the air tightness testing instrument to complete the air tightness test of the motor controller.
[0051] For example, the frame 1 is provided with a fixing block 5, the fixing block 5 is provided with a limiting groove, and a limiting block 501 is movably provided in the limiting groove. When the motor controller is delivered to the detection area, the limiting block 501 pops out to limit the movement.
[0052] It should also be noted that the purpose of setting the fixed block 5 and the limit block 501 is that when the motor controller is delivered to the corresponding position, the limit block 501 pops out to limit the motor controller.
[0053] For example, the frame 1 is provided with a rotary motor, and the rotary motor has a stop on its rotating shaft. The rotary motor adjusts the position of the stop to limit the motor controller by rotating the rotating shaft.
[0054] It should also be noted that the purpose of setting up the rotary motor is to limit the direction of the motor controller entering the detection area after the motor controller is limited by the limit block 501, so as to prevent the motor controller from shifting its position.
[0055] For example, a drive device is provided on the frame 1, which is used to drive the air inlet pipe 302 and the plurality of sealing plugs 303 to move closer to or away from the detection area.
[0056] It should also be noted that the driving device can be a cylinder, which drives the air intake pipe 302 and multiple sealing plugs 303 to move closer to or away from the opening of the motor controller, thereby sealing the opening of the motor controller and ensuring the stability of the closed environment during airtightness testing.
[0057] For example, a photoelectric switch 7 is installed on the detection bracket 301.
[0058] It should also be noted that the purpose of the photoelectric switch 7 is to detect the presence, position, or state of an object by emitting light and receiving reflected or transmitted light. In the production process of the drive motor controller, the photoelectric switch 7 can accurately position the component or product to be detected, ensuring that it is detected in the correct location and avoiding wear and errors caused by mechanical contact. At the same time, its fast response speed and high detection accuracy can significantly improve detection efficiency and quality.
[0059] For example, a barcode reader 8 is provided on the detection bracket 301.
[0060] It should also be noted that the barcode reader 8 can quickly identify the barcode or QR code on the drive motor controller, realize automated tracking and identification, reduce the time and error of manual operation. Compared with manual input and inspection, the barcode reader 8 can accurately read and record information, greatly reducing errors caused by human factors.
[0061] For example, an alarm device 9 is provided on the rack 1.
[0062] It should also be noted that the alarm device 9 is a three-color buzzer alarm device, which is a device that combines light and sound alarm functions. The three-color buzzer alarm device usually consists of three different colored lights, red, green and yellow, and a buzzer.
[0063] For example, a maintenance baffle is provided on the frame 1, and the maintenance baffle is located on both sides of the conveying assembly 2.
[0064] It should also be noted that the purpose of setting up maintenance barriers is to provide external shielding and protection for the production process, so as to avoid the impact of the external environment on the production process.
[0065] For example, a display screen is provided on the maintenance baffle.
[0066] It should also be noted that the purpose of setting up the display screen is to show the airtightness test results, making it easier for operators to observe and record.
[0067] For example, a plurality of vertically arranged limiting rods are provided on the frame 1, and the ends of the limiting rods are provided with limiting parts horizontally, which are used to limit the height of the support plate.
[0068] It should also be noted that the purpose of setting the limit rod is to limit the height of the motor controller during the upward movement of the support plate 401, so as to avoid the position of the motor controller being deviated, which would cause the air inlet pipe 302, the sealing plug 303 and the pressure sensor 403 to block the opening of the motor controller, thus affecting the measurement effect.
[0069] In summary, the airtightness testing device of this utility model allows the conveying assembly 2 to move while the motor controller is being conveyed. The lifting unit 402 drives the support plate 401 upwards, causing the motor controller located on the support plate 401 to move upwards. During this upward movement, the air inlet pipe 302, the sealing plug 303, and the pressure sensor 403 respectively seal and clamp the opening of the motor controller, creating a closed environment within the motor controller's cavity. After sealing, air is introduced into the motor controller through the air inlet pipe 302. The pressure change is observed using an airtightness testing instrument to complete the airtightness test of the motor controller. After the test is completed, the clamping on the motor controller can be quickly released, and the lifting unit 402 drives the support plate 401 downwards, placing the motor controller onto the conveying assembly 2 for the next process. This saves a significant amount of time and improves work efficiency.
[0070] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
