Technical Field

[0001] The utility model relates to the technical field of punching devices, in particular to a punching device for processing mobile phone accessories. Background Art

[0002] Mobile phones are made up of various components and have precise structures. During the processing of mobile phone accessories, drilling is one of the essential processes. At this time, special drilling equipment is usually required to perform the drilling operation. By precisely controlling the position and depth of the drill bit, the drilling requirements of protective cases or other accessories can be efficiently completed, ensuring production efficiency and product quality.

[0003] The punching device can improve the processing rate of mobile phone accessories, but it still has certain problems: a single accessory fixture cannot adapt to the punching operation requirements at different angles and positions. Therefore, when a single accessory is punched at different positions, the fixture needs to be replaced frequently, which delays the processing efficiency. Therefore, in view of the above situation, there is an urgent need to develop a punching device for mobile phone accessories processing to overcome the shortcomings in current practical applications and meet current needs.

[0037] Working principle: Mobile phone accessories are loaded at the loading station 30, and then the mobile phone accessories are punched at the subsequent four punching stations 40, and finally the punched mobile phone accessories are unloaded at the unloading station 50, thus completing the complete punching process. When loading at the loading station 30, the cylinder a302 drives the connecting rod 303 and the unlocking member 304 to descend, and the unlocking member 304 contacts the end of the pressing crank 2032 and forces it to flip outward around the hinge position. At this time, the mobile phone accessories are placed in the accessory fixture 203, and then the cylinder a302 is reset. Under the action of the torsion spring, the pressing crank 2032 is reset and the mobile phone accessories are pressed against the pressing end to fix them in the accessory fixture 203 to realize the loading operation. After the loading is completed, the turntable 10 is driven by the external driving device to rotate a specific angle until it moves to the next station; during the punching station 40 processing, if the angle of the mobile phone accessories needs to be rotated, the unlocking component 404 is first started, and the cylinder d4041 drives the connecting frame 4042 and the cylinder e4043 to descend, and the unlocking kit 4044 is nested on the unlocking protrusion 2062 of the locking component 206, and then the cylinder e4043 is started and drives the locking protrusion 2067 to disengage from the fixed position. Position the disk 204. At this time, the rotating shaft 202 can rotate freely. The cylinder b4021 of the driving component 402 drives the cylinder c4023 and the motor a4025 to descend until the coupling 4026 at the end of the motor a4025 is horizontally aligned with the docking piece 4021. At this time, the cylinder c4023 drives the motor a4025 and the coupling 4026 to move horizontally toward the docking piece 4021 until the coupling 4026 is adapted to the docking piece 4021. At this time, the motor a4025 drives the rotating shaft 202 and the accessory fixture 203 to rotate a specific angle, and then the unlocking component 404 and the driving component are unlocked. Component 402 is reset in sequence. During this process, under the action of spring 2065, locking protrusion 2067 is embedded in the positioning groove of positioning plate 204 again to lock the rotating shaft 202. Finally, motor b4034 is driven down by electric cylinder 4031, and mobile phone accessories are punched by motor b4034 and the drill bit installed on its output shaft. After the punching is completed, the turntable 10 rotates to the next station; the unloading station 50 has the same structure as the loading station 30.
