Problems solved by technology

The position of the rear end cap is relatively random due to the manual placement of the rear end cap, and the insulating strip on it is difficult to meet the above-mentioned angle requirements. Therefore, it is necessary to correct the position of the rear end cap after placement, and it is necessary to spend a lot of money to correct the rear end cap by human eyes. It takes a lot of energy and time, and the effect of correction is difficult to guarantee

Embodiment Construction

[0036]The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0037] The invention provides a rear end cap correction device capable of correcting the position of the rear end cap of the earphone, and also provides an earphone positioning jig for fixing the earphone used in conjunction with the rear end cap correction device.

[0038] Such as image 3 As shown, the rear end cap 8 is manually attached to the rear end of the earphone body 9, and is loaded and fixed into the corresponding clamp 7 together, and clamps of different specifications should be provided for different types of earphones. The clamp 7 has a positioning plate 70, and the positioning plate 70 is used to fix the clamp 7 to the earphone positioning jig. The front end of the clamp 7 has an accommodating groove whose shape corresponds to the earphone main body 9, and the earphone main body 9 is vertically put into the accommodating groove, so t...

Abstract

The invention discloses an earphone positioning jig and is used for fixing a fixture. A positioning plate of the fixture is parallel to a front end face of an earplug of an earphone. The earphone positioning jig comprises a jig base plate, a wedge block, a positioning mechanism, a compression bar and a drive mechanism. The wedge block is fixed on the jig base plate. An included angle between the front end face and the rear end face of the wedge block is equal to the product included angle of the earphone. The positioning plate is fixed on the front end face of the wedge block through the positioning mechanism. The front end of the compression bar is a fork structure and compresses the rear end cover of the earphone. The drive mechanism is arranged on the jig base plate and drives the compression bar to move away from the rear end cover. When a calibration device carries out calibration through utilization of the positioning jig, a calibration demand can be satisfied by adjusting the rear end cover of the earphone to a position where an insulation strip is parallel to the rear end face of the wedge block, while the position of the end face of the wedge block is unchanged, so no matter where the initial position of the rear end cover is, the rear end cover only needs to be adjusted to a preset position, and the calibration operation is simple. The invention also discloses the calibration device capable of calibrating a position of a rear end cover.

Description

technical field [0001] The invention relates to a calibration device for a rear end cover of a Bluetooth earphone, in particular to an earphone positioning jig used for calibration of the rear end cover. Background technique [0002] Such as figure 1 The bluetooth earphone shown structurally includes an earphone main body 9 , a front cover and a rear end cover 8 . The front end of the earphone main body 9 has an earplug part 91 which is hollow inside and has an open front side. Rear end cap 8 is fixed on the end of the straight cylindrical structure of earphone main body 9 rear ends, and rear end cap 8 has two functions: one is to encapsulate the rear end of earphone main body 9, and the other is as the charging plug of bluetooth earphone. [0003] The rear end cover 8 as a charging plug includes a conductive positive pole portion 81, a negative pole portion 82, and an insulating strip 83 connected and fixed between the positive pole portion 81 and the negative pole portio...
