Check valves are crucial components in filters, primarily used to prevent oil backflow; their assembly quality directly affects the filter's performance and lifespan. Currently, filter check valve assembly is mostly done manually or semi-automatically, resulting in low efficiency and poor consistency. Traditional assembly methods typically use a single material tray for feeding, requiring machine shutdown for replenishment, leading to reduced production efficiency. In light of this, the inventor has developed a new invention. Utility Model Content

Detailed Implementation

[0022] The following is in conjunction with the appendix Figures 1 to 5 This utility model will be described in detail.

[0023] This utility model discloses a semi-automatic assembly device for a filter check valve, comprising a feeding mechanism 1 and an assembly mechanism 2. The feeding mechanism 1 is equipped with a first preparation tray 11 and a second dispensing tray, both of which are provided with a plurality of material troughs 13 for stacking check valves. The feeding mechanism 1 is also equipped with a preparation platform 14 and a first picking device 3, which is equipped with a first picker 31. The first picker 31 can grab the check valves in the material troughs 13 and place them on the preparation platform 14. The check valve of this solution is referenced. Figure 5This is a ring structure, mainly used for oil circuit check valves at the oil inlet of filters, especially spin-on fuel filters. Spin-on fuel filters are common filters on the market and belong to mature existing technology. The specific structure will not be described in detail in this utility model. In this solution, the first preparation tray 11 and the second preparation tray 12 have the same shape, and the material trough 13 has a certain depth to stack multiple check valves. When the equipment is running, the first feeder 31 will grab the check valves in the first preparation tray 11 in a certain order until the check valves in the material trough 13 of the first preparation tray 11 are consumed. Then the first feeder 31 will move to the second preparation tray 12 to repeat the grabbing action. The moving trajectory and grabbing frequency of the first feeder 31 are preset to achieve perfect grabbing and consumption of check valves. After the check valve of the first material preparation tray 11 is depleted, the first feeder 31 moves to the second material preparation tray 12 to pick up materials. The operator can then remove the empty first material preparation tray 11 and replace it with the first material preparation tray 11 filled with the check valve. This completes the filling of the first material preparation tray 11. The first material preparation tray 11 and the second material preparation tray 12 can be filled and fed alternately. There is no need to stop the machine during the replenishment of materials, and the feeding speed is fast.

[0024] More specifically, a lifting device 15 is provided below both the first and second material preparation trays 11 and 12, and the first and second material preparation trays 11 and 12 are placed on the lifting device 15. When the check valve on the first material preparation tray 11 is depleted, the first feeder 31 moves to the corresponding position of the second material preparation tray 12. At this time, the lifting device 15 below the first material preparation tray 11 is activated, driving the first material preparation tray 11 to move downwards. After the worker replaces the first material preparation tray 11, the worker can manually control the lifting device 15 to reset, causing the first material preparation tray 11 to rise back to its original position. The lifting device 15 allows the worker to easily identify which material preparation tray needs filling by observing the downward position of the first or second material preparation tray 11, providing high convenience.

[0025] The feeding mechanism 1 is equipped with sensors 16 for sensing the positions of the first and second preparation trays 11 and 12. After the first or second preparation tray 12 descends, it leaves the sensing range of the corresponding sensor 16. At this point, the machine determines that the first or second preparation tray 11 or 12 is in a ready-to-go state. When the first picker 31 moves to a designated position, if the corresponding preparation tray is in a ready-to-go state, the first picker 31 and the conveying device 21 enter a pause state until the operator manually operates the lifting device 15 to reset the first or second preparation tray 11 or 12. Once the sensor 16 detects the first or second preparation tray 11 or 12, the ready-to-go state at that position ends, and the first picker 31 and the conveying device 21 resume operation. This structure prevents the first picker 31 from grabbing empty trays, which could lead to filter assembly errors, resulting in high stability. In addition, the sensor 16 can be linked with components such as warning lights. When the first material tray 11 or the second material tray 12 has descended to a lower position, the sensor 16 can no longer detect the position of the first material tray 11 or the second material tray 12. In this case, it will provide information to the staff by illuminating the warning light or making a warning sound, which is highly convenient.

[0026] The assembly mechanism 2 is equipped with a material conveying device 21, which has an assembly platform 22 for placing filter components. The assembly platform 22 can move on the material conveying device 21, and the material conveying device 21 is equipped with a limiter 23 to restrict the movement of the assembly platform 22. A second material picking device 4 is provided above the material conveying device 21. The second material picking device 4 is equipped with a second picker 41 that can reciprocate between the preparation platform 14 and the assembly platform 22. The second picker 41 can pick up check valves and assemble them onto the filter components on the assembly platform 22. The material conveying device 21 is used to transport the assembly platform 22 from external workstations and to transport the assembly platform 22 with assembled check valves out. The mobile assembly platform 22 allows the assembly mechanism 2 to only assemble check valves, eliminating the need for complex operations and resulting in high assembly efficiency. After the assembly table 22 moves to a specific position, it will be stopped by the limiter 23 to stop the displacement action. The position where the assembly table 22 stops corresponds to the position of the second picker 41. The second picker 41 picks up the check valve from the preparation table 14 and assembles the check valve onto the filter component of the assembly table 22 to complete the assembly.

[0027] The first material handling device 3 is equipped with a first guide rail 32, a first movable block 33 that can move along the first guide rail 32, a second guide rail 34 that can move along the first guide rail 34, and a second movable block 35 that can move along the second guide rail 34. The second movable block 35 is equipped with a first cylinder 36 that can extend downwards. The first material handling device 31 is connected to the first cylinder 36. Both the first movable block 33 and the second movable block 35 are driven by a motor to move. The first guide rail 32 and the second guide rail 34 are relatively perpendicular. The displacement of the first movable block 33 can drive the first material handling device 31 to move along the X-axis, and the displacement of the second movable block 35 can drive the first material handling device 31 to move along the Y-axis. The first cylinder 36 can drive the first material handling device 31 to move up and down, realizing multi-directional precise material handling.

[0028] Both the first and second feeders 31 have two or more suction cups 42 arranged at equal intervals. (Reference) Figure 5 The check valve shown has a shape with a gap in the middle that fits over the oil outlet of the filter. These check valves are typically made of soft plastic, making it difficult for a single traditional suction cup 42 to grip them evenly. Using grippers or similar devices can easily scratch or cut the check valve. This solution uses a combination of multiple suction cups 42 for the first and second feeders 31, allowing for balanced negative pressure suction gripping of the check valve from multiple angles. Furthermore, each suction cup 42 is externally connected to an air pipe and an air pump. The air pump should have negative pressure detection. If either the first or second feeder 31 fails to grip the check valve, the air pump will not detect the corresponding negative pressure value, and the machine will pause to alert the operator and prevent filter assembly errors.

[0029] The second material handling device 4 is sequentially equipped with a third guide rail 43, a second cylinder 44 slidably connected to the third guide rail 43, and a drive device 45 that drives the second cylinder 44 to move. The second material handler 41 is connected to the second cylinder 44. The drive device 45 drives the second cylinder 44 to move along the third guide rail 43, causing the second material handler 41 to move linearly on the material preparation table 14 and the material conveying device 21, ensuring precise control of the material handling and assembly process. The second cylinder 44 drives the second material handler 41 to move up and down, enabling the second material handler 41 to complete the grabbing and lowering displacement actions. After the second material handler 41 grabs the check valve and moves it above the assembly table 22, the second cylinder 44 drives the second material handler 41 to move downward, causing the check valve to be fitted onto the filter component to complete the assembly, ensuring precise and rapid assembly.

[0030] The material conveying device 21 is equipped with two parallel conveyor belts 24 with a gap between them. The assembly table 22 rests on both sides of the conveyor belts 24. The material conveying device 21 is equipped with limiting baffles 25 to restrict the vertical movement of the assembly table 22. Both ends of the conveyor belts are nearly aligned with both ends of the material conveying device 21. The distance between the two ends of the conveyor belts 24 is slightly less than the length of the material conveying device 21. This allows the material conveying device 21 of the assembly mechanism 2 to be connected to the material conveying equipment of other filter assembly stations for easy loading and unloading of the assembly table 22. The position of the limiting baffles 25 corresponds to the second feeder 41. When the second feeder 41 assembles the check valve onto the filter component on the assembly table 22, it prevents accidental displacement of the assembly table 22, ensuring high stability.

[0031] The limiter 23 is positioned between the two conveyor belts 24. A third cylinder 26 is connected below the limiter 23, which drives the limiter 23 to extend and restrict the forward movement of the assembly table 22. When the assembly table 22 is transported in from the outside, the third cylinder 26 drives the limiter 23 to extend. After the assembly table 22 moves to a specific position, it is stopped by the limiter 23 and stops moving forward. At this point, the check valve can be assembled onto the filter component of the assembly table 22. The transport device is also equipped with a pressure sensor 27 that abuts against the third cylinder 26. When the assembly table 22 touches the limiter 23, it will cause an impact, which will trigger the pressure sensor 27, allowing the machine to determine that the assembly table 22 is in position.

[0032] The system includes a frame 5, on which both the feeding mechanism 1 and the assembly mechanism 2 are mounted. An electrical box 51, supplying power to the feeding mechanism 1 and the assembly mechanism 2, is located within the frame 5. An emergency stop button 52 is also installed on the frame 5. This design features an independent frame 5, which facilitates movement and assembly, and is compact in structure and size. With the electrical box 51, it can be used independently as an assembly device. In the event of equipment malfunction or other unexpected safety incidents, operators can press the emergency stop button 52 to disconnect the power supply to the electrical box 51, instantly stopping the feeding mechanism 1 and the assembly mechanism 2, thus enhancing safety precautions.

[0033] The above description is only a preferred embodiment of this utility model. For those skilled in the art, there will be changes in the specific implementation and application scope based on the idea of ​​this invention. The content of this specification should not be construed as a limitation of this utility model.
