Special mounter for shielding cap

Abstract

The invention discloses a special mounter for a shielding cap, which comprises a main frame, a board conveying device, a Y-axis arch frame assembly, an X-axis arch frame assembly, a mounting head assembly and a feeding platform, wherein the moving side edge of the board conveying device is provided with a width regulation motor; and the Y-axis arch frame assembly and the X-axis arch frame assemblyform an XY moving platform of the mounting head assembly. Through arranging the width regulation motor, a stop block, a board entering sensor, a mounting sensor, a board exiting sensor and the like,the size of the shielding cap can be matched, the width of the board conveying device is adjusted, and the board conveying working position is high in accuracy and safety; through arranging the special mounting head assembly, the size of the shielding cap can be matched thoroughly, nozzle synchronous working can be kept, and the mounting efficiency is effectively enhanced; through arranging a coupling to be connected with a motor shaft and a shaft, elastic movement in the moving process is avoided, and the mounting accuracy and the stability are ensured; and through arranging the special feeding platform, the feeding accuracy is ensured, and the feeding efficiency is improved.

Description

technical field [0001] The invention relates to a placement machine, in particular to a special placement machine for shielding covers. Background technique [0002] With the rapid development of electronic information technology, the requirements for the efficiency and stability of various types of electronic products are getting higher and higher, and the equipment related to information communication has higher requirements for the efficiency and stability of information transmission. Therefore, a large number of electronic products will design various metal shielding covers according to the signal distribution to reduce external interference and improve the stability of electronic products. [0003] The placement machine is usually composed of an XY precision positioning platform and a placement head with a placement function. The material rack is usually fixedly installed on one side of the chip mounter body. In each working cycle of the chip mounter, the chip head mus...

AI Technical Summary

Problems solved by technology

The shape of the shielding cover has certain irregularities due to size changes. At present, the general-purpose placement machines in the market cannot be processed and placed, and only some of the latest improved foreign placement machines can be placed.

It has obvious defects: ①Due to the large variation in the mounting size of the shielding cover, the distance between the suction heads of the machine is not enough, and many of them can only be used with a single head, so the production efficiency is low; Low; ③The stability and precision of the spline shaft, synchronous wheel, and belt mechanism used in the general-purpose placement head are difficult to meet the placement accuracy
