Description

Technical Field

[0001] This utility model relates to the field of leak detection, and in particular to a semi-automatic leak detection device. Background Technology

[0002] In the industrial manufacturing sector, airtightness leak detection is a crucial step in ensuring the quality of sealed components (such as pipes and containers). Existing testing equipment often employs a single-station, single-person operation model, meaning there is only one testing station, and employees must sequentially complete a single cycle of "feeding-testing-retrieving." Under this model, employees are idle during equipment testing (such as the pressure holding phase), making it impossible to manage multiple machines simultaneously, resulting in severely low personnel utilization. Furthermore, the single-station serial operation creates a "testing-waiting" process; for example, testing 100 products requires 100 independent cycles, with the total time far exceeding the actual operating time, leading to significant waste of production time. In addition, the equipment lacks multi-station throughput capabilities, making it difficult to integrate with automated production lines and adapt to the demands of large-scale production. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a semi-automatic leakage device. Through modular design and semi-automatic processes, it improves detection efficiency, thereby solving the problem of "single-station operation leading to both low labor efficiency and low working hours".

[0004] This utility model is achieved using the following technical solution: a semi-automatic leakage device, comprising: The rotating assembly consists of a fixed base for the disc, a rotary cylinder, a rotating disc, and a lower molded base. The rotating disc is movably mounted above the fixed base for the disc and is driven by the rotary cylinder to rotate above the fixed base for the disc. The output end of the rotary cylinder is connected to the central axis of the rotating disc. The rotating disc has four stations evenly distributed around its circumference, and a lower molded base is fixed at each station. The sealing detection assembly includes a lower leak type, an upper leak type, and a lower type connecting nozzle. The lower type connecting nozzle is fixed to the upper end of the lower type base and its side is connected to an external air source. It also includes a bracket for mounting the lower leak type and the upper leak type. The lower leak type is fixedly connected to the bracket near the bottom and is correspondingly positioned directly below the upper leak type. The bracket also has a drive assembly on its outer side that drives the upper leak type to descend and engage with the lower leak type, thus completing the clamping and detection of the product.

[0005] Preferably, each station of the rotating disk is provided with two working positions, and the lower leakage type and the upper leakage type are provided with one set for each working position.

[0006] Preferably, the rotary cylinder drives the rotating disk to rotate by 90 degrees each time, so as to realize the sequential cyclic flow of the four workstations.

[0007] Preferably, the driving component includes an electromagnetic block and an electromagnetic rail. The electromagnetic rail is vertically fixed to the outside of the bracket, and the electromagnetic block is connected to the upper part of the leakage type and can slide along the electromagnetic rail for limiting.

[0008] Preferably, the driving component further includes an electromagnetic controller, which is electrically connected to the electromagnetic block and the electromagnetic rail. The electromagnetic controller can electrically drive the electromagnetic block to slide the upper leak mold along the electromagnetic rail, thereby achieving the clamping of the product between the lower leak mold and the upper leak mold.

[0009] Preferably, a connecting seat is fixedly connected to the bottom of the bracket, and the connecting seat is connected to the upper end of the lower mold base by fasteners. When the connecting seat installs the bracket on the upper end of the lower mold base, the leaking lower mold and the lower mold connecting nozzle are assembled vertically.

[0010] Preferably, four circuit protection boxes are fixedly connected to the upper end of the rotating disk. The four circuit protection boxes are set one-to-one with the four workstations, and their interiors contain electrical circuits that connect the rotary cylinder, electromagnetic controller and air source control valve.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: The semi-automatic leakage device of this utility model, through its multi-station layout, electromagnetically driven semi-automatic operation, and modular structure design, has the following beneficial effects: (1) The “four-station + dual workstation per station” design is adopted, and the rotating cylinder drives the rotating disk to realize the station flow, so that “product loading - air tightness detection - station switching” form a parallel operation process. Compared with traditional single-station equipment, the detection efficiency is significantly improved and the detection time of a single product is greatly shortened.

[0012] (2) During the equipment testing process, employees can simultaneously put products into the idle workstations without waiting for the single workstation testing cycle to end, which significantly improves the effective utilization rate of personnel working hours and reduces labor costs.

[0013] (3) By coordinating the electromagnetic controller, electromagnetic block and electromagnetic rail, the lifting and sealing actions of the upper leak type are precisely controlled to ensure the sealing accuracy of the lower and upper leak types. Combined with the above stable "filling-pressurizing" detection logic, the misjudgment caused by sealing error is reduced and the reliability of air tightness detection is improved.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Please combine Figure 1-2 A semi-automatic leak detection device is a multi-station airtightness testing device, whose core consists of a rotating component, a sealing detection component, a drive component, and a mobile APP control module. The components are modularly integrated, achieving continuous operation of "feeding-detection-transfer" through mechanical connections and electrical coordination. The rotating assembly, as the core carrier of the workstation transfer, undertakes the multi-station cyclic transfer function. It consists of a circular fixed base 2, a rotary cylinder 3, a rotating disk 1, and a lower mold base 4. The rotating disk 1 is movably set above the circular fixed base 2 and is driven by the rotary cylinder 3 to rotate above the circular fixed base 2. The output end of the rotary cylinder 3 is connected to the central axis of the rotating disk 1. The rotating disk 1 has four workstations evenly distributed around its circumference, and each workstation is fixed with a lower mold base 4. It should be noted that the rotating disk 1 is made of die-cast aluminum alloy with a diameter of 600mm and a thickness of 10mm. The four workstations are evenly distributed around its circumference, with adjacent workstations having an included angle of 90 degrees. Each workstation surface is fixed with two lower mold bases 4 by M8 hexagon socket bolts. The lower mold base 4 is 50mm high, and its bottom is connected to the rotating disk 1 by threads. The top has a φ30mm groove for positioning and installing the leaking lower mold 7. It should also be noted that the rotary cylinder 3 is a SMCCDRQ2BS63-180S type vane cylinder with a rated working pressure of 0.4-0.6MPa. The bottom of the cylinder body is rigidly connected to the positioning hole of the disc fixed base 2 through a flange. The output shaft is fixed to the central shaft of the rotating disc 1 through a keyway. The rotation angle is 90 degrees for each drive.

[0021] The sealing detection assembly detects leaks through "upper and lower mold fitting and sealing + air pressure monitoring." It includes a lower leak mold 7, an upper leak mold 8, and a lower mold connecting nozzle 5. The lower mold connecting nozzle 5 is fixed to the upper end of the lower mold base 4 and has a side connection to an external air source. It also includes a bracket for mounting the lower leak mold 7 and the upper leak mold 8. The lower leak mold 7 is fixedly connected to the bracket 6 near the bottom and is positioned directly below the upper leak mold 8. The bracket 6 also has a drive assembly 9 on its outer side that drives the upper leak mold 8 to descend and engage with the lower leak mold 7, thus completing the product clamping and detection. It should be noted that the lower connector 5 is a chrome-plated brass connector. One end is sealed to the leaking lower connector 7 via an O-ring and fluororubber, while the other end is connected to an external air source pipeline via a 6mm inner diameter PU air tube. An SMCITV2030-312BL pressure regulating valve is connected in series on the pipeline, which can precisely control the inflation pressure range of 4-15kPa.

[0022] The drive assembly 9 is used to control the lifting and lowering of the upper leak type 8. It adopts "electromagnetic rail guidance + controller closed-loop control" and includes an electromagnetic block 91 and an electromagnetic rail 92. The electromagnetic rail 92 is vertically fixed to the outside of the bracket 6. The electromagnetic block 91 is connected to the upper leak type 8 and can slide along the electromagnetic rail 92. The drive assembly 9 also includes an electromagnetic controller 93. The electromagnetic controller 93 is electrically connected to the electromagnetic block 91 and the electromagnetic rail 92. The electromagnetic controller 93 can electrically drive the electromagnetic block 91 to move the upper leak type 8 to slide along the electromagnetic rail 92, so as to realize the clamping of the product between the lower leak type 7 and the upper leak type 8.

[0023] It should be noted that the electromagnetic rails 92 consist of two parallel stainless steel rails, each 300mm long, fixed to the side frame of the equipment via angle brackets. The electromagnetic block 91 contains a neodymium iron boron permanent magnet and is encased in an aluminum alloy shell. It is connected to the electromagnetic rails 92 via a slider, with a rated traction force of 500N, capable of smoothly raising and lowering the leakage upper type 8. The electromagnetic controller 93, model SMCEX260-SDN1, is connected to the electromagnetic block 91 and the ECU controller via signal lines, and can receive commands to achieve a three-stage action of "descent-pressure holding-ascent". Circuit protection box 51: Made of ABS engineering plastic injection molding, installed 100mm to the left of the rotating disk 1. It integrates air switch, relay and wiring terminal, and houses the electrical circuits connecting the rotary cylinder 3, electromagnetic controller 93 and pressure sensor. The outlet is sealed with a gland and has an IP54 protection rating. Finally, it should be noted that the mobile APP control module adopts existing commercially available technologies. For the sake of convenience in the subsequent description of the embodiments, it is briefly stated here that the mobile APP control module of this utility model adopts the common "APP-cloud platform-remote module-ECU" communication architecture. Among them, the remote module is Guangzhou Jukong GRM530, which supports 4G / WiFi networking and is connected to the device ECU model STM32F103 via RS485 interface with a baud rate of 9600bps. The mobile APP interface has "Start Detection", "Emergency Stop", and "Parameter Setting" buttons, which can display the pressure value of each station and the detection status OK / NG in real time. When a leak is detected, the APP immediately pushes an alarm message and illuminates the red indicator light on site. After receiving the APP command, the ECU controller synchronously coordinates the start and stop of the rotary cylinder 3, the action of the solenoid block 91, and the on / off of the air source. At the same time, it collects pressure sensor data at a sampling frequency of 10Hz to determine whether the sealing requirements are met.

[0024] Example: Based on the above structural configuration and supplements, this device, when in use: S1, staff log in to their accounts via mobile APP, select "standard testing mode", set inflation pressure to 8kPa, pressure holding time to 5s, and rotation interval to 10s. The parameters are synchronized to the ECU controller via cloud platform. S2, the employee puts the product to be tested into the two leakage under-type 7 cavities of station 1, and the bottom of the product fits into the positioning boss of the cavity; S3, click the "Start Detection" button in the APP. The electromagnetic controller 93 drives the electromagnetic block 91 to descend along the electromagnetic rail 92, causing the upper leakage type 8 and the lower leakage type 7 to fit together and seal. At the same time, the ECU controls the air source to fill the air through the lower type connection nozzle 5. The pressure sensor provides real-time feedback data. If the pressure fluctuation during the pressure holding period is ≤0.2kPa, it is considered qualified. S4, after the test is completed, the electromagnetic block 91 drives the upper leakage mold 8 to rise and reset, the rotary cylinder 3 drives the rotating disk 1 to rotate 90 degrees, station 1 moves to the unloading position, and station 2 moves to the test position; It should be added that while employees are unloading materials at station 1, they are also putting new products into station 2 for leakage type 7, repeating steps S3-S4 to achieve parallel operation of "detection-loading-unloading", which significantly increases the detection volume per hour.

Any changes, modifications, substitutions, combinations, or simplifications made without departing from the spirit and principle of the present utility model shall be considered equivalent substitutions and shall be included within the protection scope of the present utility model.
