Description

Technical Field

[0001] This application relates to the field of automated testing equipment technology, and in particular to an automatic feeding device for an airtightness testing machine. Background Technology

[0002] With the continuous improvement of industrial automation, industries such as automobiles, electronics, and medical devices have increasingly stringent requirements for product quality and safety. Therefore, airtightness testing has become an indispensable part of the production process.

[0003] In related technologies, the traditional method of material loading before airtightness testing is still mainly manual. Workers need to move heavy material boxes one by one to the testing station, which is inefficient. In recent years, some companies have tried to introduce semi-automatic equipment to assist in material loading, but this is limited by cost and technological maturity.

[0004] The existing methods for feeding materials to be tested have the following problems: manual feeding is not only inefficient, but also increases the labor intensity and safety hazards of workers, and cannot meet the high-efficiency requirements of modern production lines. Utility Model Content

[0005] To improve testing efficiency, this application provides an automatic feeding device for an airtightness testing machine.

[0006] The automatic feeding device for an airtightness testing machine provided in this application adopts the following technical solution: An automatic feeding device for an airtightness testing machine includes a carrying component, a transport component, and a lifting component. The carrying component includes a first frame, a second frame, a base plate, and a connecting plate. The transport component includes a first conveyor belt rotatably supported on the first frame and a second conveyor belt on the second frame. The lifting component is fixed to the base plate and connected to the first frame through the connecting plate. The lifting component is used to drive the first frame to rise, so that the first conveyor belt is level with the second conveyor belt, and cooperates with the transport component to deliver the material box to the testing station.

[0007] By adopting the above solution, after the lifting assembly drives the first frame to rise, the first conveyor belt and the second conveyor belt cooperate to form a continuous transport plane, which enables the material box to be accurately pushed to the inspection station, reducing manual intervention and improving inspection efficiency.

[0008] Preferably, the lifting assembly includes a cylinder and a sprocket drive structure. The sprocket drive structure includes two meshing driven sprockets and a longitudinal chain. The cylinder is fixed to the base plate. The cylinder's push rod extends and retracts vertically and is horizontally connected to a crossbar. The two driven sprockets are rotatably supported at both ends of the crossbar. The longitudinal chain surrounds the driven sprockets and its two ends are fixedly connected to the base plate and the connecting plate, respectively.

[0009] By adopting the above scheme, when the cylinder push rod extends or retracts, it drives the driven sprockets on both sides to rotate synchronously through the crossbar. The longitudinal chain is displaced under the meshing action of the sprockets, which converts the linear motion of the cylinder into a lifting action, thereby improving the transmission efficiency and load-bearing capacity.

[0010] Preferably, the lifting assembly further includes two sets of sliding guide rails and guide blocks, and brackets are provided on both sides of the cylinder. The guide rails are fixed on the brackets, and the outer wall of the guide block is threadedly connected to the connecting plate.

[0011] By adopting the above scheme, it is ensured that the first frame moves linearly in the vertical direction during the lifting process, reducing motion deviation caused by off-center loading. Preferably, both the first conveyor belt and the second conveyor belt are composed of a number of horizontally rolling, spaced rollers.

[0012] By adopting the above scheme, the material box and the rolling contact surface only make point contact, reducing frictional resistance and facilitating labor-saving material conveying.

[0013] Preferably, the rollers on the first conveyor belt and the second conveyor belt are connected in pairs via belt drive.

[0014] By adopting the above solution, it can be ensured that all rollers rotate synchronously, thereby improving conveying accuracy.

[0015] Preferably, a liftable baffle is provided at the middle and end of the first conveyor belt, and the distance between the two liftable baffles can only accommodate one material box at a time.

[0016] By adopting the above solution, the double baffle structure forms a physical isolation zone, which can force the material boxes to maintain a single-row order during the conveying process and reduce the occurrence of stacking or collisions.

[0017] Preferably, the lifting direction of the two liftable baffles is opposite to that of the first conveyor belt.

[0018] By adopting the above scheme, when the first conveyor belt rises, the two liftable baffles descend synchronously, forming a dynamic obstacle avoidance channel in the vertical direction, allowing the material box to be transported to the second conveyor belt without obstruction.

[0019] Preferably, both the first frame and the second frame are provided with foot cups at their bottoms.

[0020] By adopting the above solution, the vibration and impact during the start and stop of the conveyor belt can be absorbed, thereby improving its vibration resistance.

[0021] In summary, this application includes at least one of the following beneficial technical effects: 1. After the lifting assembly drives the first frame to rise, the first conveyor belt and the second conveyor belt cooperate to form a continuous transport plane, which accurately pushes the material box to the inspection station, reduces manual intervention and improves inspection efficiency; 2. Improved the conveying accuracy and transmission efficiency of the device; 3. It improves the load-bearing capacity and vibration resistance of the device. Attached Figure Description

[0026] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0027] This application discloses an automatic feeding device for an airtightness testing machine. (Refer to...) Figure 1-3 An automatic feeding device for an airtightness testing machine includes a carrying component 1, a transport component 2, and a lifting component 3. The carrying component 1 includes a first frame 11, a second frame 12, a base plate 14, and a connecting plate 13. The transport component 2 includes a first conveyor belt 21 rotatably supported on the first frame 11 and a second conveyor belt 22 on the second frame 12. The lifting component 3 is fixed to the base plate 14 and connected to the first frame 11 through the connecting plate 13. The lifting component 3 is used to drive the first frame 11 to rise, so that the first conveyor belt 21 is aligned with the second conveyor belt 22, and cooperates with the transport component 2 to deliver the material box to the testing station.

[0028] Therefore, the first conveyor belt 21 has a height difference with the second conveyor belt 22 in the initial state, so that the operator can move heavy material boxes onto the first conveyor belt 21. After the lifting component 3 drives the first frame 11 to rise, the height of the first conveyor belt 21 is flush with the second conveyor belt 22, forming a continuous transport plane, ensuring lifting stability and transport continuity.

[0029] Furthermore, the material box passes through the first conveyor belt 21 and the second conveyor belt 22 in succession, and is finally smoothly pushed to the inspection station. Compared with the traditional feeding method, this effectively reduces manual intervention and labor intensity, and improves feeding speed and inspection efficiency.

[0030] Specifically, the lifting assembly 3 includes a cylinder 31 and a sprocket drive structure 33. The sprocket drive structure 33 includes two meshing driven sprockets 331 and a longitudinal chain 332. The cylinder 31 is fixed on the base plate 14. The push rod of the cylinder 31 extends and retracts in the vertical direction and is horizontally connected to a crossbar 32. The two driven sprockets 331 rotate and are supported at both ends of the crossbar 32. The longitudinal chain 332 surrounds the driven sprockets 331 and its two ends are fixedly connected to the base plate 14 and the connecting plate 13, respectively.

[0031] Correspondingly, when the cylinder 31 push rod extends, the crossbar 32 moves upward, causing the driven sprocket 331 to rotate. The longitudinal chain 332 pulls the connecting plate 13 and the first frame 11 to lift, so that the first conveyor belt 21 is aligned with the second conveyor belt 22. When the cylinder 31 push rod retracts, the driven sprocket 331 reverses, and the longitudinal chain 332 relaxes and releases the load, achieving a smooth reset.

[0032] In summary, when the cylinder 31 push rod extends or retracts, it drives the driven sprockets 331 on both sides to rotate synchronously through the crossbar 32. The longitudinal chain 332 is displaced under the meshing action of the sprockets, which converts the linear motion of the cylinder 31 into a lifting action. The double-sided sprocket design ensures the synchronicity of lifting and reducing the load on one side. It also reduces the stroke of the cylinder 31 through the amplification effect of the sprocket and chain drive, effectively improving the load-bearing capacity and transmission efficiency.

[0033] Meanwhile, the lifting assembly 3 also includes two sets of sliding guide rails 35 and guide blocks 36. Brackets 34 are installed on both sides of the cylinder 31. The guide rails 35 are fixed on the brackets 34, and the outer wall of the guide block 36 is threadedly connected to the connecting plate 13.

[0034] Therefore, the guide rail 35 and the guide block 36 slidably disposed on the guide rail 35 constitute a precision guiding system to ensure that the first frame 11 moves linearly in the vertical direction during the lifting process, reducing the occurrence of movement deviation caused by off-center load. The threaded connection between the guide block 36 and the connecting plate 13 allows for adjustment of the preload. The operator can eliminate the transmission gap by tightening the nut, thereby suppressing the vibration generated by the first frame 11 and the first conveyor belt 21 during vertical displacement.

[0035] Furthermore, the brackets 34 on both sides of the cylinder 31, together with the guide rail 35, form a symmetrical support structure. When the cylinder 31 push rod extends or retracts, the power and load are transmitted through the guide block 36-guide rail 35 pair, reducing the risk of deformation caused by stress concentration and ensuring the synchronicity and repeatability of the lifting action.

[0036] On the other hand, the bottom of both the first frame 11 and the second frame 12 is equipped with feet (not shown in the attached figure), which can compensate for uneven ground in the conveyor belt docking scenario, reduce equipment displacement, absorb vibration impact when the conveyor belt starts and stops, reduce vibration transmission between adjacent frames, improve vibration resistance and load-bearing performance, and are suitable for uneven load conditions of conveyor belt transportation systems.

[0037] In the process described above, both the first conveyor belt 21 and the second conveyor belt 22 are composed of several horizontally rolling, spaced rollers, so that the material box only makes point contact with the rolling contact surface during transportation. This reduces the energy consumption of the conveying by lowering the coefficient of friction, making it suitable for long-distance transportation of heavy materials.

[0038] Furthermore, individual rollers can be replaced independently when damaged, reducing downtime and improving maintenance convenience.

[0039] Specifically, several rollers on the first conveyor belt 21 and the second conveyor belt 22 are connected in pairs via belt 23 to achieve multi-roller linkage. The belt 23 connects adjacent rollers to achieve forced synchronous rotation, ensuring that the speed of each section of the conveyor belt is consistent, thereby reducing the speed deviation between rollers, reducing workpiece offset caused by roller speed differences, improving positioning and conveying accuracy, and making it suitable for low-speed, high-torque material transportation scenarios.

[0040] Furthermore, the elasticity of belt 23 can absorb about part of the vibration energy, making the material box transmission smoother, and the failure of a single belt 23 only affects two adjacent rollers, and the equipment can still operate at a reduced speed.

[0041] Meanwhile, a liftable baffle 24 is installed at the middle and end of the first conveyor belt 21, and the distance between the two liftable baffles 24 can only accommodate one material box at a time, and the lifting direction of the liftable baffles 24 is opposite to that of the first conveyor belt 21.

[0042] Correspondingly, when the first conveyor belt 21 descends, the two liftable baffles 24 rise synchronously, forming a physical isolation zone in front and behind. This forces the material boxes to maintain a single-row order during the conveying process, reducing the occurrence of box stacking or collisions. It also facilitates the interception of subsequent material boxes in emergency stop situations, or allows for the tracking and tracing of products that fail the airtightness test.

[0043] Furthermore, when the first conveyor belt 21 rises, the two liftable baffles 24 descend synchronously, forming a dynamic obstacle avoidance channel in the vertical direction, reducing mechanical interference, and allowing the material box to be transported to the second conveyor belt 22 without obstruction.

[0044] The implementation principle of the automatic feeding device for an airtightness testing machine in this application embodiment is as follows: The device is designed with an initial height difference to facilitate manual loading of heavy material boxes. The lifting component 3 then raises the first conveyor belt 21 to the same height as the second conveyor belt 22 to form a continuous transport surface, so that the material box can smoothly reach the testing station by passing through the two conveyor belts in sequence. Compared with the traditional feeding method, it effectively reduces manual intervention and labor intensity, while improving the feeding speed and testing efficiency.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
