Description

Technical Field

[0001] This utility model relates to the field of sealing tester technology, and in particular to a vacuum sealing tester with loading and unloading functions. Background Technology

[0002] A vacuum seal tester is an instrument used to test the vacuum seal performance of a sealed container. It determines the quality of the seal by applying a negative pressure inside the container and then observing whether any leaking gas enters the container. Vacuum seal testers are commonly used in food packaging, pharmaceutical packaging, and electronic component encapsulation to ensure the quality and safety of product packaging.

[0003] Most current vacuum seal testing instruments create a pressure difference between the inside and outside of a sample immersed in water by evacuating the vacuum chamber. They then observe the gas escape from the sample to determine its sealing performance. For example, Chinese Patent Publication No. CN210625951 U discloses a seal testing instrument, which includes a base, a transparent barrel, and a lid that covers the transparent barrel. The front end of the base is equipped with an operation panel, and an air pump is installed inside the base. The air pump is connected to the lid through a hose. When the lid is closed on the transparent barrel, the air pump can evacuate the transparent barrel.

[0004] The existing vacuum seal tester has a rather cumbersome operating procedure, requiring operators to manually place the test sample. This process is not only time-consuming but also increases labor costs, thereby reducing the overall testing efficiency. In addition, since the sample is tested in water, there will be residual moisture on the sample surface after the test. This not only affects the subsequent processing of the sample but also requires additional manual drying, further increasing the complexity and time cost of the operation. Utility Model Content

[0005] The purpose of this invention is to solve the problem in the existing technology that requires operators to manually place test samples, and to propose a vacuum sealing tester with loading and unloading functions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] Design a vacuum sealing tester with loading and unloading functions, including a chassis, with a conveying component one and a conveying component two for conveying test samples respectively at both ends of the chassis. The conveying component one and the conveying component two have the same structure. A transverse mechanism for transferring test samples is provided inside the chassis. A sealing test component for testing the sealing performance of test samples is also provided on the chassis.

[0008] Drying mechanisms are provided on both sides of the chassis. The drying mechanisms are used to dry the test samples after the test is completed. A guiding mechanism is also provided on the conveying component.

[0009] Furthermore, the lateral movement mechanism includes a fixed base, on which a slide rod and a lead screw are respectively provided. The lead screw is driven by a motor, and a cylinder is threadedly connected to the lead screw. The cylinder is slidably connected to the slide rod, and an electric gripper is connected to the telescopic end of the cylinder.

[0010] Furthermore, the sealing detection component includes a base, which is fixedly connected to the bottom of the chassis. A transparent barrel is fixedly connected to the upper end of the base, and a vacuum pump is fixedly connected to the upper end of the chassis. The vacuum pump is connected to the transparent barrel through a pipe, and a barrel cover is provided between the telescopic end of the cylinder and the electric gripper.

[0011] Furthermore, the drying mechanism includes a fixed frame that is slidably connected to the inner wall of the machine casing, a heating wire is provided on the fixed frame, and a fan is fixedly connected to the fixed frame.

[0012] Furthermore, both sides of the chassis are provided with a slot, and an L-shaped connecting block is slidably connected to the slot. The L-shaped connecting block is fixedly connected to the fixing frame. A U-shaped frame is provided between the two L-shaped connecting blocks. A slot is provided on one side of the slot. Both ends of the U-shaped frame pass through the L-shaped connecting blocks and are fixedly connected to the ends with locking blocks. The locking blocks engage with the slots. Springs are provided at both ends of the U-shaped frame.

[0013] Furthermore, the guiding mechanism includes a telescopic plate, one end of which is rotatably connected to the conveying component. Two rotating shafts are rotatably connected to one side of the housing, and sprockets are fixedly connected to the rotating shafts. The two sprockets are connected by a chain, and connecting rods and L-shaped connecting rods are respectively provided on the upper and lower sides of the chain. One end of the connecting rods and L-shaped connecting rods is rotatably connected to the telescopic ends of the two telescopic plates, respectively. A worm gear is fixedly connected to one of the rotating shafts. Two mounting seats are provided on one side of the housing, and a worm is rotatably connected between the two mounting seats. The worm meshes with the worm wheel, and a crank is provided at one end of the worm.

[0014] The present invention provides a vacuum sealing tester with loading and unloading functions, which has the following advantages: In the present invention, both the first conveying component and the second conveying component are conveyor belts. First, the first conveying component transports the test sample into the machine box. Then, the transverse mechanism transfers the test sample from the first conveying component to the sealing test component for testing. After the test is completed, the transverse mechanism transfers the test sample from the sealing test component to the second conveying component. Finally, the second conveying component is responsible for unloading the test sample, thus completing the entire testing process.

[0015] Secondly, in this invention, after the test is completed, the drying mechanism dries the test sample to remove residual moisture. At the same time, the guiding mechanism centers the test sample to ensure the accuracy of the sample during transportation and facilitates the transverse mechanism to effectively transfer the test sample.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Reference Figure 1-4A vacuum sealing tester with loading and unloading functions includes a housing 1. At both ends of the housing 1 are a first conveying component 11 and a second conveying component 12 for conveying test samples. The first conveying component 11 and the second conveying component 12 have the same structure. A transverse mechanism 2 for transferring test samples is provided inside the housing 1. A sealing detection component 13 for detecting the sealing performance of the test samples is also provided on the housing 1. In this invention, both the first conveying component 11 and the second conveying component 12 are conveyor belts. First, the first conveying component 11 conveys the test sample into the housing 1. Then, the transverse mechanism 2 transfers the test sample from the first conveying component 11 to the sealing detection component 13 for testing. After testing, the transverse mechanism 2 transfers the test sample from the sealing detection component 13 back to the second conveying component 12. Finally, the second conveying component 12 unloads the test sample, completing the entire testing process.

[0025] Drying mechanisms 3 are provided on both sides of the housing 1. The drying mechanisms 3 are used to dry the test samples after the test is completed. A guiding mechanism 4 is also provided on the conveying component 11. In this utility model, after the test is completed, the drying mechanism 3 will dry the test sample to remove residual moisture. At the same time, the guiding mechanism 4 is used to center and position the test sample to ensure the accuracy of the sample during the conveying process and to facilitate the transverse mechanism 2 to effectively transfer the test sample.

[0026] Furthermore, the transverse mechanism 2 includes a fixed base 21, on which a slide rod 22 and a lead screw 23 are respectively provided. The lead screw 23 is driven by a motor 24, and a cylinder 25 is threadedly connected to the lead screw 23. The cylinder 25 is slidably connected to the slide rod 22, and an electric gripper 26 is connected to the telescopic end of the cylinder 25. In this invention, the motor 24 drives the lead screw 23 to rotate, thereby driving the cylinder 25 to move. When it is necessary to transfer the test sample, the cylinder 25 is first moved above the first conveying component 11, and then the cylinder 25 drives the electric gripper 26 to move downward. The electric gripper 26 grabs the test sample. The operator or the automatic control system will guide the combined movement of the cylinder 25 and the electric gripper 26 to transfer the test sample from its original position to the sealing detection component for sealing detection. After the detection is completed, the transverse mechanism 2 transfers the test sample to the second conveying component 12 for discharge.

[0027] Furthermore, the sealing detection component 13 includes a base 131, which is fixedly connected to the bottom of the chassis 1. A transparent barrel 132 is fixedly connected to the upper end of the base 131, and a vacuum pump 133 is fixedly connected to the upper end of the chassis 1. The vacuum pump 133 is connected to the transparent barrel 132 through a pipe 134. A barrel cover 135 is provided between the telescopic end of the cylinder 25 and the electric gripper 26. In this invention, the transparent barrel 132 is used to fill with water to form a water bath environment. When the transverse mechanism 2 moves the test sample into the transparent barrel 132, the barrel cover 135 is placed on the barrel to seal the space inside the barrel. Subsequently, the vacuum pump 133 is used to extract the air inside the transparent barrel 132, thereby creating a negative pressure environment inside the barrel. Since the test sample is immersed in water, the negative pressure inside the barrel will cause a pressure difference between the inside and outside of the sample. By observing the escape of gas from the inside of the test sample, the sealing performance of the sample can be evaluated.

[0028] The drying mechanism 3 includes a fixed frame 31, which is slidably connected to the inner wall of the housing 1. A heating wire 32 is provided on the fixed frame 31, and a fan 33 is fixedly connected to the fixed frame 31. In this invention, the heat generated by the heating wire 32 is blown towards the test sample by the fan 33, which accelerates the drying process of the sample. The hot air blown out by the fan 33 can effectively improve the drying efficiency and shorten the drying time of the test sample.

[0029] Furthermore, both sides of the chassis 1 are provided with slots 34, and L-shaped connecting blocks 35 are slidably connected to the slots 34. The L-shaped connecting blocks 35 are fixedly connected to the fixing frame 31. A U-shaped frame 36 is provided between the two L-shaped connecting blocks 35. A slot is provided on one side of the slots 34. Both ends of the U-shaped frame 36 pass through the L-shaped connecting blocks 35 and are fixedly connected to the ends with locking blocks 37. The locking blocks 37 engage with the slots. Springs 38 are provided at both ends of the U-shaped frame 36. In this utility model, the fixing frame 31 is slidably connected to the inner wall of the chassis 1. Next, the spring force of the spring 38 pushes the locking block 37 to engage with the slot, thereby fixing and positioning the mounting bracket 31. When the position of the mounting bracket 31 needs to be adjusted, the operator can pull the U-shaped bracket 36. Pulling the U-shaped bracket 36 will separate the locking block 37 from the slot, releasing the fixed state of the mounting bracket 31, allowing it to move to a new position along the sliding connection inside the chassis 1. After the adjustment is completed, release the U-shaped bracket 36, and the spring force of the spring 38 will cause the locking block 37 to re-engage with the slot, fixing and positioning the mounting bracket 31 in the new position, thereby enabling the adjustment of the position of the fan 33.

[0030] Furthermore, the guiding mechanism 4 includes a telescopic plate 41, one end of which is rotatably connected to the conveying component 11. Two rotating shafts 42 are rotatably connected to one side of the housing 1. A sprocket 43 is fixedly connected to each rotating shaft 42. The two sprockets 43 are connected by a chain 44. Connecting rods 45 and L-shaped connecting rods 46 are respectively provided on the upper and lower sides of the chain 44. One end of each connecting rod 45 and L-shaped connecting rod 46 is rotatably connected to the telescopic ends of the two telescopic plates 41. A worm gear 47 is fixedly connected to one of the rotating shafts 42. Two mounting seats 48 are provided on one side of the housing 1. A worm 49 is rotatably connected between the two mounting seats 48. The worm 49 meshes with the worm gear 47. A crank is provided at one end of the worm 49. In this invention, the sprocket 43 and the chain 44 constitute a synchronous belt drive system. The two telescopic plates are adjusted by rotating the crank. The angle between the telescopic plates 41 is adjusted to precisely position the test sample in the center, facilitating the transfer of the transverse mechanism 2. When the angle between the telescopic plates 41 needs to be adjusted, the operator turns the crank handle, which causes the worm 49 to rotate. The worm 49 meshes with the worm wheel 47, causing the worm wheel 47 to rotate as well. The rotation of the worm wheel 47 is transmitted through the rotating shaft 42, which is fixedly connected to the worm wheel 47. The upper and lower sides of the chain 44 are respectively equipped with connecting rods 45 and L-shaped connecting rods 46. One end of these connecting rods is rotatably connected to the retractable ends of the two telescopic plates 41. As the rotating shaft 42 rotates, the chain 44 moves along the sprocket 43, which causes the connecting rods 45 and L-shaped connecting rods 46 to move, thereby adjusting the angle between the telescopic plates 41. Through this adjustment, the test sample can be accurately positioned in the center, allowing the transverse mechanism 2 to easily transfer the test sample to the next processing stage.

[0031] Operating Procedure: During operation, the conveyor component 11 transports the test sample into the housing 1. Then, the motor 24 drives the lead screw 23 to rotate, which in turn moves the cylinder 25. When it is necessary to transfer the test sample, the cylinder 25 is first moved above the conveyor component 11. The cylinder 25 then drives the electric gripper 26 to move downwards, gripping the test sample and transferring it into the transparent barrel 132. At this point, the barrel lid 135 is placed over the barrel to seal the internal space. Subsequently, the vacuum pump 133 is used to extract the air from the transparent barrel 132, thereby creating a vacuum inside the barrel. A negative pressure environment is created. Since the test sample is immersed in water, the negative pressure inside the barrel will cause a pressure difference between the inside and outside of the sample. By observing the escape of gas inside the test sample, after the test is completed, the heat generated by the heating wire 32 is blown onto the test sample by the fan 33 to accelerate the drying process of the sample. The hot air blown out by the fan 33 can effectively improve the drying efficiency and shorten the drying time of the test sample. The transverse mechanism 2 transfers the test sample from the sealed detection component 13 to the second conveying component 12. Finally, the second conveying component 12 is responsible for unloading the test sample.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
