[0020] The positioning assembly 20 also includes a guide rod 24 and a buffer spring 25. The guide rod 24 is fastened to the bottom of the feeding assembly 10. The buffer spring 25 is sleeved on the guide rod 24. The slider 22 is slidably located outside the guide rod 24 and abuts against one end of the buffer spring 25.

[0021] The positioning base 21 includes a connecting plate 211, a first positioning block 212, and a second positioning block 213. The first positioning block 212 and the second positioning block 213 are symmetrically distributed on both sides of the connecting plate 211, and the first positioning block 212 and the second positioning block 213 are movable and abut against the mobile phone casing.

[0022] The guiding device is a guide rail 13, which is horizontally arranged on the lower surface of the feeding plate 11, and the positioning seat 21 is slidably engaged with the guide rail 13.

[0023] The opening and closing drive assembly 30 includes an opening and closing drive cylinder 31 and a drive base 32. The opening and closing drive cylinder 31 is vertically arranged below the feeding assembly 10. The drive base 32 is installed at the output end of the opening and closing drive cylinder 31. The drive base 32 is detachably wedge-shaped engaged with the connector 23.

[0024] The connector 23 is a roller. The feeding assembly 10 and the positioning assembly 20 are both in two sets. The drive seat 32 includes a mounting plate 321, a first wedge block 322 and a second wedge block 323. The first wedge block 322 and the second wedge block 323 are symmetrically arranged on both sides of the mounting plate 321.

[0025] The slider 22 is slidably located on the feeding assembly 10 and is securely connected to the positioning seat 21. The connecting piece 23 is detachably wedge-shaped and engaged with the output end of the opening and closing drive assembly 30. This design allows the driving force of the opening and closing drive assembly 30 to be effectively transmitted to the positioning seat 21, enabling the positioning seat 21 to move. The wedge-shaped engagement converts the vertical driving force into a lateral positioning action, resulting in a simple structure and high transmission efficiency.

[0026] The guide rod 24 is securely mounted below the feeding assembly 10, and the slider 22 can slide on its outer side, providing precise guidance for the movement of the slider 22 and ensuring the linearity and stability of the positioning seat 21. The buffer spring 25 is sleeved on the guide rod 24 and abuts against the slider 22. It plays a buffering role when the positioning seat 21 presses against the mobile phone casing, avoiding damage to the mobile phone casing due to excessive impact force and improving the product yield.

[0027] Positioning base 21: The first positioning block 212 and the second positioning block 213 are symmetrically distributed on both sides of the connecting plate 211 and can move to abut against the phone casing. This symmetrical structure can position the phone casing from both sides simultaneously, making the positioning more uniform and stable, and ensuring that the phone casing can be accurately fixed in all directions.

[0028] Opening / closing drive cylinder 31 and drive base 32: The opening / closing drive cylinder 31 is vertically positioned below the feeding assembly 10, and the drive base 32 is mounted on its output end. The vertically positioned cylinder saves lateral space, making the entire clamping structure more compact. The detachable wedge-shaped engagement between the drive base 32 and the connecting piece 23 (roller) allows for flexible control of the positioning assembly 20's movement as needed, achieving fast and accurate positioning and unlocking operations.

[0029] Drive base 32 (mounting plate 321, first wedge block 322, and second wedge block 323): The first wedge block 322 and the second wedge block 323 are symmetrically arranged on both sides of the mounting plate 321, and respectively wedge-shapedly engage with the two rollers. This symmetrical design can simultaneously drive the two sets of positioning components 20, ensuring the consistency and synchronization of the actions of the two sets of positioning components 20, and improving the overall stability and reliability of the positioning of the mobile phone casing.

[0030] The guide rail 13 provides precise guidance for the movement of the positioning seat 21, reducing deviations during its movement and enabling it to accurately press against or move away from the phone casing, further improving positioning accuracy and stability. Through the sliding engagement between the positioning seat 21 and the guide device, and the pressing action of the first positioning block 212 and the second positioning block 213 on the positioning seat 21 against the phone casing, precise positioning of the phone casing on the feeding assembly 10 can be achieved, ensuring the precision of laser engraving.

[0031] Easy to operate: The opening and closing drive component 30 drives the positioning component 20 to press against or move away from the mobile phone casing through a wedge-shaped engagement. The operation is simple. The positioning and unlocking process can be completed by simply controlling the action of the opening and closing drive cylinder 31, which improves production efficiency.

[0032] Buffer protection: The buffer spring 25 in the positioning component 20 can play a buffering role during the positioning process, reduce the impact on the phone casing, avoid damage to the phone casing due to collisions during the positioning process, and reduce the defect rate.

[0033] Reasonable structure: The layout of the feeding component 10, positioning component 20 and opening and closing drive component 30 is reasonable. The components work together, the overall structure is compact, and it occupies little space, making it suitable for application on mobile phone manufacturing production lines.

[0034] The phone case is placed in the receiving groove 111 of the feeding plate 11, abutting against the stop block 12 to complete the initial positioning. The opening and closing drive cylinder 31 is activated, and the drive seat 32 moves upward. Due to the wedge-shaped engagement between the roller and the wedge block, the upward movement of the drive seat 32 pushes the roller to move to both sides, thereby causing the slider 22 to slide on the guide rod 24. The positioning seat 21 moves along the guide rail 13 towards the phone case, and the first positioning block 212 and the second positioning block 213 gradually press against the phone case to achieve precise positioning. During the positioning process, the buffer spring 25 plays a buffering role to reduce the impact force on the phone case. The opening and closing drive cylinder 31 is controlled to move downward, and the drive seat 32 moves downward accordingly. The slider 22 and the positioning seat 21 move away from the phone case, releasing the positioning of the phone case. At this time, the engraved phone case can be taken out.

[0035] The usage method and principle of this positioning fixture structure for laser engraving of mobile phone cases are as follows: The mobile phone case is placed on the feeding assembly, which provides a base for its placement. The opening and closing drive assembly is activated, providing power for the positioning process. The opening and closing drive assembly drives the positioning assembly. Due to the sliding engagement between the positioning seat of the positioning assembly and the guide device on the feeding assembly, the positioning seat moves along the guide device towards the mobile phone case on the feeding assembly under the drive of the opening and closing drive assembly. The positioning seat gradually approaches the mobile phone case until it presses against it, thus positioning the mobile phone case and ensuring its fixed position during laser engraving. After the mobile phone case is precisely positioned by the positioning assembly, laser engraving is performed, engraving the desired patterns, text, etc., onto the mobile phone case. After laser engraving is completed, the opening and closing drive assembly is controlled to reverse its movement. The opening and closing drive assembly drives the positioning seat of the positioning assembly to move in the opposite direction along the guide device, moving the positioning seat away from the mobile phone case and releasing the positioning of the mobile phone case.

[0036] The key design feature of this invention is that it achieves precise positioning and convenient operation of the mobile phone casing by employing a feeding component, a positioning component, and an opening / closing drive component. The feeding component provides the function of placing and initially positioning the mobile phone casing, the positioning component achieves precise positioning of the mobile phone casing through sliding fit and wedge drive, and the opening / closing drive component provides power for the positioning and unlocking process. The guide device guides the positioning seat and prevents position deviation. The entire positioning fixture has a compact structure, is easy to operate, and has accurate positioning, which can meet the needs of laser engraving production of mobile phone casings.
