Dispensing device for magnetic head bearing cap and dispensing technology

Abstract

The invention discloses a dispensing device for a magnetic head bearing cap. The device comprises a supporting platform, a cabinet rack, a positioning mechanism, a dispensing mechanism, an adhesive drying mechanism and a control system. The positioning mechanism comprises a slide assembly and a workpiece clamping assembly. The workpiece clamping assembly comprises a handle, a supporting plate anda compression structure used for compressing workpieces. The compression structure is fixedly arranged on the supporting plate. A workpiece pick-and-place station, a workpiece dispensing station and aworkpiece adhesive-drying station are successively arranged on the supporting platform. The dispensing mechanism and the adhesive drying mechanism are respectively positioned above the workpiece dispensing station and the workpiece adhesive-drying station, and are controlled by the control system. With the arrangement of the compression structure with unique and novel design, fixation and pick-and-place of workpieces can be realized, and operation is convenient. According to the dispensing device, adhesive amount can be precisely controlled through a dispensing valve; the adhesive can be accurately sent to an assigned position through a dispensing needle; and by regulating an air pressure valve to control a light source emitter, adhesive solidification rate can reach 100%.

Description

technical field [0001] The invention relates to a glue dispensing device and a glue dispensing process thereof, in particular to a glue dispensing device and a glue dispensing device for assembling a magnetic head bearing cover in a hard disk and a glue dispensing process thereof, belonging to the technical field of computer applications. Background technique [0002] The physical structure of the hard disk can be divided into two parts: the external structure and the internal structure. From the outside, the structure of the hard disk mainly includes three parts: the metal fixed panel, the control circuit board and the interface; when you open the hard disk shell, you can see the internal structure of the hard disk, including There are so many components in the magnetic head assembly, magnetic head drive assembly, platter, spindle assembly, front control circuit, etc., it can be seen that the production of a hard disk requires a long process and complicated processes.

Problems solved by technology

[0004] However, dispensing is a process of applying, potting, and dripping electronic glue, oil or other liquids on the product, so that the product can play the role of sticking, potting, insulating, fixing, and smooth surface. The scope of application It is very extensive, and applying dispensing technology to the assembly process of hard disk heads not only needs to consider the accuracy of the dispensing position, the accuracy of the glue amount, whether the glue is completely cured, and whether it matches the non-standard hard disk head, etc. Factors, but also need to consider cost performance and mechanical trial, etc., involving many factors, there is no available technology
