Description

Technical Field

[0001] This utility model relates to the field of aerosol can testing, and in particular to an aerosol can water bath leak detection device. Background Technology

[0002] After aerosol cans are filled, they need to undergo an airtightness test to ensure they do not leak during transportation or storage. One method of airtightness testing is water bath leak detection, which involves immersing the aerosol can in water and observing whether bubbles are generated on its surface. If bubbles are present, it indicates a leak. Currently, leak detection for aerosol cans only involves immersing them in water; the cans cannot be rotated in the water. This prevents workers from conducting a comprehensive inspection of the cans and accurately pinpointing the location of leaks.

[0003] CN202323302266 discloses a water bath leak detection device for aerosols, comprising: a top plate, a bottom plate, and a water tank. Sliding blocks are slidably connected to both sides of the interior of the top plate. A cube is fixedly connected to the bottom of each of the two sliding blocks. A clamping arm is movably mounted on the bottom of each of the two cubes. A magnetic suction plate is fixedly connected to the side of each clamping arm that is close to each other. A protrusion is fixedly connected to the bottom of each of the two cubes. A trapezoidal column is slidably connected inside each of the two protrusions. The side of each trapezoidal column that is close to each other is movably engaged with the side of the corresponding clamping arm that is far away from each other. The two clamping arms are disposed on the top of the same water tank. This leak detection device uses the clamping arms to hold the aerosol and immerse it in water for leak detection. However, the device cannot rotate the aerosol during the leak detection process.

[0004] The technical problem that this invention needs to solve is: how to enable the aerosol can to rotate during water bath leak testing. Utility Model Content

[0005] The main purpose of this utility model is to provide a water bath leak detection device for aerosol cans. By setting rollers on the grippers, the two grippers clamp the aerosol cans through the rollers. The lifting unit drives the grippers to descend and presses the bottom of the aerosol can against the rotating plate. The rotating plate rotates, thereby driving the aerosol can to rotate, making it convenient for staff to observe the various positions of the aerosol cans.

[0006] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0007] A water bath leak detection device for aerosol cans includes a frame, a clamping unit, a lifting unit, and a rotating unit;

[0008] The frame is equipped with a water tank;

[0009] The clamping unit includes a support frame, a first drive module, and grippers. The two grippers are slidably connected to the support frame. The first drive module is connected to the support frame and is used to drive the two grippers to move closer or further apart. The grippers are provided with rollers, which extend vertically in the axial direction and are used to contact the outer surface of the aerosol can.

[0010] The lifting unit is connected to the frame, and the support frame is connected to the lifting unit. The lifting unit is used to drive the support frame to move up and down.

[0011] The rotating unit includes a second drive module and a rotating disk. The second drive module is connected to the frame, and the power output end of the second drive module passes through the water tank and is fixedly connected to the rotating disk. The rotating disk is used to drive the aerosol can to rotate.

[0019] Compared with existing technologies, this solution has the following advantages:

[0020] The aerosol can water bath leak detection device in this case features rollers mounted on the grippers, which clamp the aerosol cans. This not only clamps the cans but also allows them to rotate on the rollers. A lifting unit drives a support frame, which in turn lowers the grippers and aerosol cans onto a rotating disc inside the water tank. The rotating disc, through friction, causes the aerosol cans to rotate, enabling comprehensive observation of the cans. Furthermore, by using rollers to grip the aerosol cans, the contact area between the grippers and the cans is reduced, allowing for more thorough observation of leaks at different locations on the cans.

Detailed Implementation

[0026] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of this application implemented as described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0027] Example 1

[0028] refer to Figure 1-4 A water bath leak detection device for aerosol cans includes a frame 1, a clamping unit 2, a lifting unit 3 and a rotating unit 4;

[0029] The frame 1 is equipped with a water tank 11;

[0030] The clamping unit 2 includes a support frame 21, a first drive module 22, and two grippers 23. The two grippers 23 are slidably connected to the support frame 21. The first drive module 22 is connected to the support frame 21 and is used to drive the two grippers 23 to move closer or further away from each other. The grippers 23 are provided with rollers 24, which extend vertically in the axial direction and are used to contact the outer surface of the aerosol can 7.

[0031] The lifting unit 3 is connected to the frame 1, and the support frame 21 is connected to the lifting unit 3. The lifting unit 3 is used to drive the support frame 21 to move up and down.

[0032] The rotating unit 4 includes a second drive module 41 and a rotating disk 42. The second drive module 41 is connected to the frame 1. The power output end of the second drive module 41 passes through the water tank 11 and is fixedly connected to the rotating disk 42. The rotating disk 42 is used to drive the aerosol can 7 to rotate.

[0033] In this embodiment, the first drive module 22 consists of a first motor 221 and a bidirectional lead screw 31222. The top of the support frame 21 is provided with a groove. The two ends of the bidirectional lead screw 31222 are rotatably connected to the inner wall of the groove. The first motor 221 is installed on the side of the support frame 21. The power output end of the first motor 221 is fixedly connected to one end of the bidirectional lead screw 31222.

[0034] The bottom of the groove is provided with a strip-shaped through hole. The gripper 23 is placed in the groove, and the free end of the gripper 23 passes through the strip-shaped through hole. The strip-shaped through hole can prevent the gripper 23 from shaking when moving. The two grippers 23 are respectively connected to the two ends of the bidirectional lead screw 31222. When the bidirectional lead screw 31222 rotates, the two grippers 23 will move closer to each other or further away from each other, thereby realizing that the two grippers 23 clamp the aerosol can 7 or release the aerosol can 7.

[0035] The lifting unit 3 includes a lead screw 31, a second motor 32, and a guide shaft 33. The lead screw 31 and the guide shaft 33 are rotatably connected to both sides of the frame 1, respectively. The two ends of the support frame 21 are connected to the lead screw 31 and the guide shaft 33, respectively. The second motor 32 drives the lead screw 31 to rotate, which in turn drives the support frame 21 to move up and down, thereby causing the gripper 23 and the aerosol can 7 to enter or leave the water tank 11. By setting the guide shaft 33, the stability of the movement of the support frame 21 can be improved.

[0036] The second drive module 41 is the third motor.

[0037] The specific working process of this leak detection device is as follows: Water is injected into the water tank 11. After the water injection is completed, the first drive module 22 drives the two grippers 23 to move closer together, so that the rollers 24 on the grippers 23 clamp the aerosol can 7. After clamping, the lifting unit 3 drives the support frame 21 to move downward, thereby moving the aerosol can 7 on the grippers 23 downward to the rotating disk 42. After the bottom of the aerosol can 7 contacts the rotating disk 42, the second drive module 41 drives the rotating disk 42 to rotate, causing the aerosol can 7 to rotate on the rollers 24. Thus, during the water bath leak detection process, the staff can observe from all directions whether the aerosol can 7 is leaking. After the detection is completed, the second drive module 41 stops working, and the lifting unit 3 drives the grippers 23 to move upward, thereby detaching the aerosol can 7 from the water tank 11.

[0038] Preferably, it further includes a water absorption unit 5; the water absorption unit 5 includes a third drive module 51, a movable frame 52, a water absorption roller 53, and a fourth drive module 54; a support plate 12 is provided on the frame 1, the third drive module 51 is connected to the support plate 12, the power output end of the third drive module 51 is fixedly connected to the movable frame 52, and the third drive module 51 is used to drive the movable frame 52 to move closer to or away from the gripper 23; the water absorption roller 53 is rotatably connected to the movable frame 52, the axial direction of the water absorption roller 53 extends vertically, and the water absorption roller 53 is used to absorb moisture from the outer surface of the aerosol can 7; the fourth drive module 54 is connected to the movable frame 52, and the fourth drive module 54 is used to drive the water absorption roller 53 to rotate.

[0039] In this embodiment, since there is moisture on the body of the aerosol can 7 after the water bath leak test, if the staff directly removes the aerosol can 7, the moisture will drip onto the ground or affect the next process. Therefore, a water absorption unit 5 is provided to absorb the moisture from the aerosol can 7 after the leak test is completed.

[0040] The third drive module 51 is a cylinder, and the fourth drive module 54 is a fourth motor. The fourth drive module 54 drives the water suction roller 53 to rotate via a belt.

[0041] The movable frame 52 is equipped with an optical axis 55, which is slidably connected to the support plate 12. By setting the optical axis 55, the stability of the movable frame 52 during movement is increased.

[0042] The specific working process of the water absorption unit 5 is as follows: the lifting unit 3 drives the gripper 23 to move upward, so that the aerosol can 7 is separated from the water tank 11. The third drive module 51 drives the moving frame 52 to move toward the aerosol can 7, so that the water absorption roller 53 on the moving frame 52 contacts the outer surface of the aerosol can 7. The fourth drive module 54 drives the water absorption roller 53 to rotate, and the water absorption roller 53 drives the aerosol can 7 to roll on the roller 24 through friction, so that the water absorption roller 53 can absorb the moisture on the surface of the aerosol can 7.

[0043] Preferably, the movable frame 52 extends a top water-absorbing plate 521 and a bottom water-absorbing plate 522 on the side facing the gripper 23. Both the top water-absorbing plate 521 and the bottom water-absorbing plate 522 are provided with sponges 523, which are used to absorb moisture from the top and / or bottom of the aerosol can 7.

[0044] In this embodiment, when the water-absorbing roller 53 comes into contact with the aerosol can 7, the sponge 523 on the top water-absorbing plate 521 comes into contact with the top of the aerosol can 7, and the sponge 523 on the bottom water-absorbing plate 522 comes into contact with the bottom of the aerosol can 7. When the water-absorbing roller 53 drives the aerosol can 7 to rotate, the two sponges 523 absorb the water from the top and bottom of the aerosol can 7 respectively.

[0045] Preferably, the gripper 23 is provided with four rollers 24, which are symmetrically arranged on both sides of the gripper 23 along the moving direction of the support frame 21, and the thickness of the rollers 24 is 15mm to 30mm.

[0046] In this embodiment, two rotatable rollers 24 are provided on one side of the gripper 23 and two rotatable rollers 24 are also provided on the other side. In this way, the rollers 24 can clamp aerosol cans 7 of different diameters.

[0047] The thickness of roller 24 is 25mm. Increasing the thickness of roller 24 can increase the friction between roller 24 and aerosol can 7.

[0048] Preferably, the rotating disk 42 is located directly below the clamping unit 2 and inside the water tank 11. The axial direction of the rotating disk 42 extends vertically, and the diameter of the rotating disk 42 is smaller than the diameter of the bottom of the aerosol can 7.

[0049] In this embodiment, the rotating disk 42 is located directly below the aerosol can 7. The rotating disk 42 can not only drive the aerosol can 7 to rotate, but also support the aerosol can 7 to prevent the aerosol can 7 from shaking or falling off the gripper 23 when rotating.

[0050] The diameter of the rotating disk 42 is smaller than the diameter of the bottom of the aerosol can 7. While ensuring that the rotating disk 42 has sufficient friction to drive the aerosol can 7 to rotate, reducing the diameter of the rotating disk 42 can reduce the contact area between the rotating disk 42 and the aerosol can 7, thereby exposing more of the aerosol can 7 to the water for leak detection.

[0051] Preferably, the surface of the roller 24 is provided with anti-slip texture, and the surface of the rotating disk 42 is provided with an anti-slip layer.

[0052] In this embodiment, by providing anti-slip textures on the roller 24, the friction between the roller 24 and the aerosol can 7 is increased, thereby increasing the clamping force of the gripper 23 on the aerosol can 7. By providing an anti-slip layer on the surface of the rotating disk 42, the rotating disk 42 can more easily drive the aerosol can 7 to rotate.

[0053] Preferably, the water tank 11 is provided with a heating module 6, which includes a heating wire 61 and a temperature sensor. The heating wire 61 is used to heat the water in the water tank 11, and the temperature sensor is used to detect the temperature of the water in the water tank 11.

[0054] In this embodiment, water bath leak detection requires placing the aerosol can 7 in water at a constant temperature for leak detection. Therefore, a heating wire 61 and a temperature sensor are provided to ensure that the temperature of the water in the water tank 11 can be maintained at a temperature that meets the detection requirements.

[0055] Preferably, the system further includes a control unit, which is communicatively connected to the clamping unit 2, the lifting unit 3, the rotating unit 4, the water absorption unit 5, and the heating module 6.

[0056] In this embodiment, the control unit is a PLC. The control unit controls the clamping unit 2, lifting unit 3, rotating unit 4, water absorption unit 5, and heating module 6, so that each unit module can operate according to the corresponding steps.
