[0023] In the description of this utility model, it should be noted that the terms "front", "up", "down", "left", "right", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] The following is in conjunction with the appendix Figure 1-9 The present invention will be further described below.

[0025] To address the problems existing in the background technology, this utility model provides a flipping device for producing mobile phone protective cases, including a belt conveyor 1, a protective cover 2 fixedly connected to the belt conveyor 1, a first conveyor belt 8 and a second conveyor belt 9 provided inside the protective cover 2, the first conveyor belt 8 and the second conveyor belt 9 twisting each other and forming a flipping channel 17, an inlet 16 provided above one end of the first conveyor belt 8, a drive assembly for driving the first conveyor belt 8 and the second conveyor belt 9 to rotate provided outside the protective cover 2, and guide plates 3 fixedly connected to both sides of the top of the belt conveyor 1, forming a guide channel between the guide plates 3, and the guide channel corresponding to the inlet 16.

[0026] Among them, the belt conveyor 1 serves as the core conveying foundation of the device, stably transporting the mobile phone cases to the flipping process, adapting to the needs of mass production lines for mobile phone cases. The belt conveyor 1 is an existing product. The protective cover 2 fixed on top is made of lightweight and wear-resistant material, providing protection for the internal first conveyor belt 8 and second conveyor belt 9, preventing external dust and impurities from interfering with the flipping process, ensuring the cleanliness of the mobile phone case surface, and also preventing operators from accidentally touching moving parts, thus improving production safety.

[0027] In this embodiment, the first conveyor belt 8 and the second conveyor belt 9, which twist to each other inside the protective cover 2, automatically flip the phone case during transport by forming a flipping channel 17 through the twisting. This eliminates the need for a complex mechanical clamping structure. This design abandons the cumbersome structure of traditional flipping devices that rely on robotic arms for gripping and flipping, reducing component wear and the probability of failure, and lowering maintenance costs. The inlet 16 at one end of the first conveyor belt 8 precisely aligns with the conveying path of the belt conveyor 1, ensuring that the phone case can smoothly enter the flipping channel 17 and avoiding problems such as jamming or deviation.

[0028] The drive assembly outside the protective cover 2 provides stable power to the conveyor belt, and the conveyor belt speed can be adjusted according to the production rhythm to adapt to the flipping requirements of different specifications of mobile phone protective cases, thus enhancing the flexibility of the device. The guide plates 3 on both sides of the top of the belt conveyor 1 form a guide channel, which corresponds to the inlet 16. This can straighten the mobile phone protective cases during the conveying process, prevent them from shifting or stacking during the conveying process, and ensure that each protective case can accurately enter the flipping channel 17 through the inlet 16, thereby improving the continuity and stability of the flipping process and ensuring the production efficiency of the assembly line.

[0029] In this embodiment, the specific twisted structure of the first conveyor belt 8 and the second conveyor belt 9 is shown in the attached drawings of the specification. A fixed frame 14 is fixedly connected inside the protective cover 2. Two torsion rollers 15 are rotatably connected in the fixed frame 14. The two torsion rollers 15 are respectively inserted into the gap between the first conveyor belt 8 and the second conveyor belt 9 to support the torsion of the first conveyor belt 8 and the second conveyor belt 9.

[0030] The fixing frame 14 inside the protective cover 2 is made of high-strength metal and is fixed to the inner wall of the protective cover 2 by welding, forming a stable support foundation. This prevents the structure from loosening due to vibration of the conveyor belt and ensures the long-term stable operation of the device. The two torsion rollers 15 rotatably connected in the fixing frame 14 have smooth surfaces, which can reduce frictional resistance with the conveyor belt and provide precise support for the first conveyor belt 8 and the second conveyor belt 9 that are twisting against each other without affecting the normal operation of the conveyor belt.

[0031] The torsion roller 15 is inserted into the gap between the first conveyor belt 8 and the second conveyor belt 9. It can limit and support the torsion angle, ensuring that the shape and size of the flipping channel 17 remain stable. This allows each mobile phone case to complete a consistent flipping action within the channel, avoiding problems such as flipping angle deviation and incomplete flipping, and improving product processing consistency.

[0032] Meanwhile, the rotational characteristics of the torsion roller 15 allow it to rotate synchronously with the conveyor belt, further reducing frictional loss, extending the service life of the conveyor belt, reducing downtime for maintenance due to conveyor belt wear, and ensuring production continuity. This support structure is simple and efficient, requiring no additional power drive, and while improving the stability of the torsion roller, it reduces the energy consumption and manufacturing cost of the device.

[0033] The protective cover 2 has a first roller 4 and a second roller 5 rotatably connected to both sides inside. The first roller 4 and the second roller 5 are provided with annular limiting openings on their outer sides. The first conveyor belt 8 is fitted in the annular limiting opening outside the first roller 4, and the second conveyor belt 9 is fitted in the annular limiting opening outside the second roller 5.

[0034] In this embodiment, the first roller 4 and the second roller 5, which are rotatably connected on both sides inside the protective cover 2, provide transmission support for the first conveyor belt 8 and the second conveyor belt 9, respectively. Their smooth rotation directly affects the running stability of the conveyor belt. The rollers are made of wear-resistant alloy material, with a smooth surface and high hardness, which can withstand the pressure and friction brought by the long-term operation of the conveyor belt, reduce their own wear, and extend their service life.

[0035] In this embodiment, the annular limiting opening outside the rotating roller provides precise positioning for the conveyor belt. The first conveyor belt 8 is fitted into the annular limiting opening of the first rotating roller 4, and the second conveyor belt 9 is fitted into the annular limiting opening of the second rotating roller 5. This effectively prevents problems such as axial deviation and slippage of the conveyor belt during operation. Traditional conveyor belts often run off-track due to the lack of a limiting structure, which not only affects the turning effect but may also cause damage due to friction between the conveyor belt and the inner wall of the protective cover 2, increasing maintenance costs. The annular limiting opening ensures that the first conveyor belt 8 and the second conveyor belt 9 always run on the preset track, ensuring the stability of the turning channel 17 and improving the reliability of the turning process.

[0036] The drive assembly includes a first motor 6 and a second motor 11 fixedly connected to the outside of the cover 2. The output end of the first motor 6 and one end of the first roller 4 are both fixedly connected to a first bevel gear 7, and the first bevel gears 7 mesh with each other. The output end of the second motor 11 and one end of the second roller 5 are both fixedly connected to a second bevel gear 12, and the second bevel gears 12 mesh with each other.

[0037] The drive assembly employs a dual-motor independent drive design. The first motor 6 provides power to the first rotating roller 4, and the second motor 11 provides power to the second rotating roller 5. Independent control allows for flexible adjustment of the rotation speeds of the first conveyor belt 8 and the second conveyor belt 9. This design adapts to the flipping requirements of different sized mobile phone cases. For thinner cases, the conveyor belt speed can be reduced to prevent the case from popping out due to excessively fast flipping; for thicker cases, the speed can be increased to ensure thorough flipping, enhancing the device's versatility.

[0038] In this embodiment, connecting frames 18 are fixedly connected to both sides of the inner side of the protective cover 2. The first guide block 10 and the second guide block 13 are fixedly connected to the two connecting frames 18 respectively. The first guide block 10 is rotatably connected to the first rotating roller 4, and the second guide block 13 is rotatably connected to the second rotating roller 5. The tops of the first guide block 10 and the second guide block 13 are both set as inclined surfaces.

[0039] The connecting frames 18 on both sides inside the protective cover 2 are fixed to the inner wall of the protective cover 2 by welding, providing a stable installation support for the first guide block 10 and the second guide block 13, ensuring that the guide blocks do not shift during the rotation of the rollers and guaranteeing the stability of the guiding effect. The rotating connection structure between the first guide block 10 and the first roller 4, and between the second guide block 13 and the second roller 5, allows the rollers to rotate smoothly under the constraint of the guide blocks, reducing radial sway during the operation of the rollers and further improving the running stability of the conveyor belt.

[0040] The sloping design at the top of the guide block plays a crucial guiding role: when the phone case enters the flipping channel 17 from the inlet 16, if there is a slight deviation, the sloping surface can guide the case, allowing it to smoothly enter the flipping area between the first conveyor belt 8 and the second conveyor belt 9, preventing jamming due to case deviation and ensuring the continuity of the flipping process. Simultaneously, the sloping structure also reduces collision and friction between the case and the guide block, preventing scratches and wear on the case surface and ensuring the product's appearance quality.

[0041] The usage method of this embodiment is as follows:

[0042] Equipment Inspection: Before starting the equipment, check whether the belt conveyor 1, the first conveyor belt 8, and the second conveyor belt 9 are damaged or jammed; check whether the wiring of the first motor 6 and the second motor 11 is secure and whether the bevel gear meshing is normal; confirm that the guard 2 is not loose and that the torsion roller 15 and the guide block are not misaligned, and ensure that all components are in normal working condition.

[0043] Parameter adjustment: According to the specifications (thickness, size) of the mobile phone protective case to be processed, the speed of the first motor 6 and the second motor 11 is adjusted by the motor controller so that the running speed of the first conveyor belt 8 and the second conveyor belt 9 is adapted to the flipping requirements of the protective case, ensuring that the flipping is smooth and thorough; if the protective case is relatively thin, the speed is appropriately reduced; if it is relatively thick, the speed is appropriately increased.

[0044] Feeding and conveying: Place the mobile phone protective cases neatly at the feed end of the belt conveyor 1, ensuring that there is no stacking between the protective cases and that they are laid flat on the conveyor belt individually; start the belt conveyor 1, and the protective cases are conveyed forward with the conveyor belt. Under the guidance of the guide plates 3 on both sides, they move precisely along the guide channel to the inlet 16 of the protective cover 2.

[0045] Automatic flipping: When the protective shell reaches the inlet 16, it automatically enters the flipping channel 17 formed by the first conveyor belt 8 and the second conveyor belt 9 under the continuous conveying of the conveyor belt; driven by the mutually twisting conveyor belts, the protective shell completes a 180-degree flip in the channel. During the flipping process, the twisting roller 15 supports the conveyor belt to ensure the stability of the flipping channel 17.

[0046] Subsequent conveying: The protective shell, after being flipped, is conveyed by the first conveyor belt 8 and the second conveyor belt 9, and is sent out from the other end of the flipping channel 17, returning to the belt conveyor 1, and is conveyed by the conveyor belt to the next production process (such as spraying, testing, etc.); throughout the process, the protective cover 2 continuously provides protection for the internal components, ensuring production safety and product cleanliness.

[0047] Shutdown maintenance: After production is completed, turn off the power to belt conveyor 1 and the motor, clean the impurities and dust from the surface of belt conveyor 1 and the conveyor belt; check whether the conveyor belt is worn, whether the bevel gear meshing part needs to be lubricated, and whether the guide block and torsion roller 15 are misaligned. Perform maintenance in a timely manner to ensure that the device can be used normally next time.
