Description

Technical Field

[0001] This utility model relates to the technical field of automated lighter production equipment, specifically a flipping mechanism for lighter production. Background Technology

[0002] In the mass production of lighters, multiple processes are required, including shell injection molding, component assembly, airtightness testing, and surface printing. Among these processes, the lighter blank or semi-finished product needs to be flipped between several steps to process or test different sides. For example, after the components on the inner side of the shell are assembled, they need to be flipped to the outer side for printing, or after the airtightness of one side is tested, it needs to be flipped to test the other side. Currently, there are two main methods for flipping lighters in the industry: one is manual flipping, where operators need to manually pick up the lighter, adjust its position, and place it on the next conveyor. This method is not only inefficient and difficult to match the pace of automated production lines, but manual contact can also easily cause stains on the lighter's surface or damage to the blank, affecting product quality consistency. The other method is to use a simple mechanical flipping structure. This type of structure usually uses a fixed clamping component in conjunction with a single rotating axis to achieve flipping. However, due to the differences in lighter specifications (such as length and diameter), the existing structure lacks a flexible positioning and adjustment mechanism, making it difficult to adapt to products of multiple specifications. In addition, the clamping force control precision is insufficient during the flipping process, which can easily lead to problems such as the lighter falling off due to excessively loose clamping or the outer shell deforming due to excessively tight clamping.

[0003] Existing mechanical flipping structures often have poor integration with the conveying mechanism, requiring additional transfer stations to pick up and transfer lighters. Some flipping mechanisms lack buffer protection components, which can easily cause wear or displacement of the lighter due to rigid collisions when the clamping parts move or flip into place, further reducing production stability. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a flipping mechanism for lighter production, which solves the problems mentioned in the background art, such as poor connection between existing mechanical flipping structures and conveying mechanisms, and the lack of buffer protection components in some flipping mechanisms.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A flipping mechanism for lighter production includes: a mounting frame, the upper surface of which is provided with a positioning mechanism, the positioning mechanism including a fixing plate fixedly connected to the upper surface of the mounting frame, a pair of threaded grooves on the left and right sides of the fixing plate, a pair of adjusting bolts threadedly connected inside the pair of threaded grooves, a pair of connecting plates fixedly connected to the output end on one side of the pair of adjusting bolts, three pairs of rotating shafts movably connected to the upper surface of the connecting plates, and three pairs of clamping rings fixedly connected to the upper surfaces of the three pairs of fixing plates.

[0006] Preferably, a support column is fixedly connected to the lower surface of the mounting frame, a mounting plate is fixedly connected to the upper surface of the mounting frame, a conveyor belt is movably connected inside the mounting plate, a pair of fixing blocks are fixedly connected to one side of the mounting plate, a pair of grooves are provided on the left and right sides of the mounting plate, and a pair of connecting blocks are fixedly connected to one side of the pair of grooves.

[0007] Preferably, the upper surface of the mounting frame is further provided with a transmission unit. The transmission unit includes an adjustment frame fixedly connected to the upper surface of the mounting frame. An adjustment plate is fixedly connected to the upper surface of the adjustment frame. A first air pump is fixedly connected to one side of the adjustment plate. A first air rod is fixedly connected to the output end of one side of the first air pump. A pair of slide rails are fixedly connected to the outer surface of the adjustment plate. A moving plate is fixedly connected to the output end of one side of the first air rod. A flipping unit is also provided on one side of the moving plate.

[0008] Preferably, a buffer unit is also provided on one side of the adjusting plate. The buffer unit includes a mounting block fixedly connected to one side of the adjusting plate, a buffer spring movably connected to one side of the mounting block, and a buffer plate fixedly connected to the output end of one side of the buffer spring.

[0009] Preferably, the flipping unit includes a drive motor fixedly connected to the upper surface of the movable plate, a rotating shaft fixedly connected to the output end of the lower surface of the drive motor, a lifting plate fixedly connected to the output end of the lower surface of the rotating shaft, a pair of clamping air pumps fixedly connected to one side of the lifting plate, a pair of sliding blocks fixedly connected to the output end of the lower surface of the pair of clamping air pumps, and a pair of clamping plates fixedly connected to the left and right sides of the pair of sliding blocks.

[0010] Beneficial effects

[0011] This invention provides a flipping mechanism for lighter manufacturing. Compared with the prior art, it has the following advantages:

[0012] By using a positioning mechanism, rotating the adjusting bolt pushes the connecting plate to move horizontally, thereby adjusting the spacing of the three pairs of clamping rings. This allows for quick adaptation and stable clamping of lighters of different lengths and diameters. The rotating shaft can flexibly rotate during the lighter's transport or flipping process, preventing scratches on the outer shell caused by rigid friction. This effectively improves product positioning accuracy and quality integrity, solving the problems of poor adaptability and easy product damage in existing structures. Through the transmission unit, the first air pump drives the first air rod, causing the moving plate to slide smoothly along the slide rail. This allows for precise transfer of the flipping unit to the corresponding position on the conveyor belt, achieving seamless integration with the transport mechanism. The seamless connection eliminates the need for additional transfer stations, significantly shortening process intervals and improving production line cycle time. Furthermore, the buffer structure, composed of mounting blocks, buffer springs, and buffer plates, absorbs impact when the moving plate slides into position, preventing mechanical wear or lighter positioning misalignment caused by rigid collisions, thus significantly enhancing equipment operational stability. Through the setting of the flipping unit, the drive motor drives the rotating shaft to move the lifting plate up and down, precisely adjusting the clamping height to accommodate lighters in different conveying positions. Additionally, a pair of clamping air pumps synchronously drive the sliding blocks, causing the clamping plate to achieve flexible clamping of the lighter, thereby replacing manual flipping operations.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1:

[0019] Please see Figure 1 - Figure 3 As shown, this embodiment proposes a flipping mechanism for lighter production, comprising: a mounting frame 1, a positioning mechanism on the upper surface of the mounting frame 1, the positioning mechanism including a fixing plate 3, threaded grooves 4, adjusting bolts 5, a connecting plate 6, a rotating shaft 7, and a clamping ring 8. The fixing plate 3 is fixedly connected to the upper surface of the mounting frame 1. A pair of threaded grooves 4 are formed on the left and right sides of the fixing plate 3. A pair of adjusting bolts 5 are threadedly connected inside the pair of threaded grooves 4. A pair of connecting plates 6 are fixedly connected to the output end of one side of the pair of adjusting bolts 5. The upper surface of the connecting plate 6 is movably connected to... Three pairs of rotating shafts 7 and three pairs of clamping rings 8 are fixedly connected to the upper surfaces of the three pairs of fixed plates 3. The adjusting bolts 5 in the threaded grooves 4 of the rotating fixed plate 3 are used to push the connecting plate 6 to move horizontally by thread engagement, thereby changing the distance between the rotating shafts 7 on the connecting plate 6 and the clamping rings 8 on the fixed plate 3 to adapt to the length and diameter of the lighter to be processed, avoiding shaking or squeezing. The conveyor belt 10 sends the lighter to the space formed by the rotating shafts 7 and the clamping rings 8. The clamping rings 8 limit the displacement from both sides. The rotating shafts 7 movably support the lighter, reduce friction and maintain a horizontal height, making it convenient for subsequent picking.

[0020] Preferred, such as Figure 1 and Figure 2 As shown, a mounting plate 9 is fixedly connected to the upper surface of the mounting frame 1. A conveyor belt 10 is movably connected inside the mounting plate 9. A pair of fixing blocks 11 are fixedly connected to one side of the mounting plate 9. A pair of grooves 12 are opened on the left and right sides of the mounting plate 9. A pair of connecting blocks 13 are fixedly connected to one side of the pair of grooves 12. The conveyor belt 10 inside the mounting plate 9 moves and transports the lighter to be flipped from the previous station of the production line to the positioning mechanism. The fixing block 11 on one side of the mounting plate 9 enhances the connection stability between the mounting plate 9 and the mounting frame 1, preventing the mounting plate 9 from deforming when the conveyor belt 10 is running. The grooves 12 on both sides of the mounting plate 9 and the connecting blocks 13 on the groove sides achieve seamless connection with the entire production line, ensuring smooth transport of lighters.

[0021] Preferred, such as Figure 2As shown, the upper surface of the mounting frame 1 is also equipped with a transmission unit, which includes an adjusting frame 14, an adjusting plate 15, a first air pump 16, a first air rod 17, a slide rail 18, a moving plate 19, a mounting block 21, a buffer spring 22, and a buffer plate 23. The adjusting frame 14 is fixedly connected to the upper surface of the mounting frame 1, and the adjusting plate 15 is fixedly connected to the upper surface of the adjusting frame 14. The first air pump 16 is fixedly connected to one side of the adjusting plate 15, and the first air rod 17 is fixedly connected to the output end of one side of the first air pump 16. A pair of slide rails 18 are fixedly connected to the outer surface of the adjusting plate 15, and the moving plate 19 is fixedly connected to the output end of one side of the first air rod 17. A flipping unit is also provided on one side of the moving plate 19. When the first air pump 16 on one side of the adjusting plate 15 is activated, it drives... The first air rod 17 at the output end extends and retracts. Since the first air rod 17 is fixedly connected to the moving plate 19, it can synchronously drive the moving plate 19 to move. A pair of slide rails 18 on the outer surface of the adjusting plate 15 guide the moving plate 19, restricting the moving plate 19 to only move horizontally along the slide rails 18, avoiding deviation, and ensuring that the moving plate 19 is accurately transferred to the positioning mechanism or the next station. When the first air rod 17 pushes the moving plate 19 closer to the adjusting plate 15, if the moving plate 19 contacts the buffer plate 23, the buffer plate 23 will compress the buffer spring 22 on the rear mounting block 21. The impact force is absorbed by the spring deformation, avoiding direct rigid collision between the moving plate 19 and the adjusting plate 15, protecting the equipment parts and the flipping unit on the moving plate, and preventing positional deviation caused by the collision.

[0022] Preferred, such as Figure 2 As shown, a buffer unit is also provided on one side of the adjusting plate 15. The buffer unit includes a mounting block 21 fixedly connected to one side of the adjusting plate 15. A buffer spring 22 is movably connected to one side of the mounting block 21. A buffer plate 23 is fixedly connected to the output end of one side of the buffer spring 22. Due to the use of the buffer unit, the buffer plate 23 and the buffer spring 22 of the buffer unit can buffer the moving plate 19 when it moves to one end.

[0023] Preferred, such as Figure 2 and Figure 3As shown, the flipping unit includes a drive motor 20, a rotating shaft 24, a lifting plate 25, a clamping air pump 26, sliding blocks 27, and clamping plates 28. The drive motor 20 is fixedly connected to the upper surface of the moving plate 19. The rotating shaft 24 is fixedly connected to the output end of the lower surface of the drive motor 20. The lifting plate 25 is fixedly connected to the output end of the lower surface of the rotating shaft 24. A pair of clamping air pumps 26 are fixedly connected to one side of the lifting plate 25. A pair of sliding blocks 27 are fixedly connected to the output end of the lower surface of the pair of clamping air pumps 26. A pair of clamping plates 28 are fixedly connected to the left and right sides of the pair of sliding blocks 27. The drive motor 20 is mounted on the moving plate 19. When the motor 20 starts, it drives the shaft 24 at the output end of the lower surface to rotate. The shaft 24 drives the lifting plate 25 fixed at the lower end to rotate. A pair of clamping air pumps 26 on one side of the lifting plate 25 starts, driving a pair of sliding blocks 27 at the output end of the lower surface to move closer together. The sliding blocks 27 drive the clamping plates 28 fixed on both sides to move synchronously, clamping the lighter from both sides to prevent it from falling off when flipped. After the clamping plates 28 clamp the lighter, they work with the transmission unit to drive the moving plate 19 to move. After the clamping plates 28 clamp the lighter, the drive motor 20 drives the shaft 24 to rotate, thereby flipping the lighter.
