Description

Technical Field

[0001] The invention relates to the field of welding jigs, in particular to a welding jig for a mobile phone vibrator. Background Art

[0002] Mobile phone vibration is a standard function in mobile phones. Mobile phone vibration is generally achieved through a mobile phone vibrator inside the mobile phone. The mobile phone vibrator includes an outer shell and an inner core actuator arranged in the outer shell. Both ends of the inner core actuator are connected to the inner wall surface of the outer shell through leaf springs. The principle is to energize the coil on the outer shell to generate a magnetic field, thereby driving the inner core actuator to vibrate. However, as mobile phones are made thinner and thinner, it is inevitable that the mobile phone vibrator will be designed to be smaller and smaller. Usually, the single-sided gap between the inner core actuator and the outer shell is only 0.18mm, which makes the assembly of the plate mobile phone vibrator more and more difficult.

[0003] In the prior art, the welding process of the mobile phone vibrator first needs to assemble the inner core mover in the outer shell, and then weld the leaf spring connected to the inner core mover to the inner wall surface of the outer shell. However, the existing method of assembling the inner core mover and the outer shell is usually to first position and fix the outer shell on a fixture, and then install the inner core mover in the outer shell. Due to manufacturing errors between the inner core mover and the outer shell, there are dimensional tolerances in the appearance of the product itself, making it difficult to ensure the central symmetry requirements of the inner core mover inside the outer shell under this assembly method. The existence of deviations will affect the vibration performance of the inner core mover.

[0004] Therefore, it is necessary to design a new technical solution to solve the above problems. Summary of the invention

[0090] Step 4, place the jig body 10 on the second drive platform, the second drive platform drives the centering positioning device 30 to leave the outer shell, and then drives the ejection device 50 to eject the inner core mover and the outer shell together, that is, drives the product disengagement handle 53 to rotate and leave the jig body 10, and then drives the mounting block 54 to rise through the rocker rod 55, so as to drive the first ejector pin 51 and the second ejector pin 52 to protrude from the top of the top wall 14 to eject the inner core mover and the outer shell together, and finally drives the limit pin 404 and the baffle 402 to reset.

[0091] The design emphasis of the present invention is:

[0092] Mainly, a positioning portion for positioning the inner core mover in the front-to-back direction is provided on the product fixing seat, and a centering positioning device is used to center the inner core mover and the outer shell left and right, and a clamping mechanism is used to center the outer shell front and back, so that the inner core mover can be accurately placed in the outer shell, ensuring the central symmetry of the inner core mover inside the outer shell, thereby ensuring the vibration performance of the inner core mover. When positioning, the inner core mover is first centered, and then the outer shell is centered, which facilitates the positioning operation of the inner core mover in the outer shell without considering the operable space in the outer shell, and the ejection and unloading device is driven to eject the inner core mover and the outer shell together, ensuring that the inner core mover and the outer shell are separated from the product fixing seat together, avoiding the problem of easy pulling damage caused by ejecting only the outer shell part.
