Description
Technical field
The present invention relates to mobile phone mounting technology fields, and in particular to a kind of positioning device of mobile phone assembling.
Background technology
Mobile phone, referred to as mobile phone or radio telephone.Mobile phone is divided into smart mobile phone and non-smart mobile phone, smart mobile phone tool
There is independent operating system, powerful practicability is high, and it includes that the third party service providers such as game carry that can voluntarily be installed by user
The program of confession, present mobile phone can not only be communicated, additionally it is possible to the activity of surfing the Internet etc. is carried out, it is very popular.
Mobile phone is assembled by multiple parts, wherein most importantly cell phone mainboard, parts are installed in hand
Mutually matched work is carried out on the mainboard of machine, to realize the various functions of mobile phone.Present electronic equipment manufacturing factory carries out hand
Machine is by man-made assembly when assembling, and operating personnel will position simultaneously the mainboard of mobile phone when being installed to mobile phone parts
And it is fixed, positioning is to enable parts being accurately mounted on mainboard, and fixation is in order to avoid in installation parts
Position offset occurs for mainboard in the process, and existing positioning method is will to be manually pressed on operation console, but manually be difficult to hold
Whether mainboard is put just, and the installation site of offset parts is easy.
Secondly, it is required that parts and mainboard keep clean in mobile phone installation process, and mainboard and parts are transporting
During can adhere to some dusts, dust can influence the conducting of circuit.
Invention content
The invention is intended to provide a kind of positioning device of mobile phone assembling, positioned with solving existing mobile phone assembling process mainboard
Inaccuracy, the problem of be easy to causeing parts position offset.
In order to achieve the above objectives, the technical scheme is that：A kind of positioning device of mobile phone assembling, including rack, behaviour
Make platform and power seat, the operation console is fixed on the rack, and the both sides of operation console slidably connect grip block, the bottom of grip block
Equipped with inclined bracing wire, the locating slot that can be pushed down on by two grip blocks is equipped between two grip blocks, locating slot is along vertical
Direction is slidably connected with operation console, and positioning trench bottom is equipped with the spring to offset with operation console；
The power seat slidably connects motor in the horizontal direction, and the output shaft of motor is equipped with sliding slot, consolidates in power seat
Surely there is the slide bar coordinated with sliding slot, the first friction plate is fixed on output shaft, side of first friction plate far from motor is equipped with interior
Mesh ratchet gear mechanism is fixed with the second friction plate that can coordinate with the first friction plate, internal messing ratchet on internal messing ratchet mechanism
Mechanism is fixed with the shaft being rotatablely connected with power seat；
Side of the power seat far from motor is equipped with the gas tank for being fixed on the rack and being connected to outside, and shaft is equipped with
Flabellum in gas tank, gas tank are equipped in the horizontal direction towards the tracheae of locating slot, and the bracing wire is wrapped in shaft.
The principle of the present invention and advantageous effect：Mainboard is positioned in locating slot, when motor drives output shaft rotation, sliding slot
Motor can be made to reciprocatingly slide in the horizontal direction with slide bar mutual cooperation, when motor is slided towards locating slot direction, and first rubs
When pad is contacted with the second friction plate, motor can drive internal messing ratchet mechanism, and internal messing ratchet mechanism can turn clockwise
Dynamic, to which internal messing ratchet mechanism can be rotated forward with shaft, shaft rotates forward with flabellum and gas tank is blowed, gas
Cognition is blowed locating slot by tracheae under the action of flabellum.During the installation process, the wind of blowout can by mainboard and
Dust on parts is blown away, and the dust on mainboard and parts is avoided to influence the circuit of parts and mainboard.
When shaft rotates, shaft can also drive bracing wire so that guy winding makes bracing wire pull clamping in shaft
Block is slided towards locating slot, and grip block can be pressed down against locating slot and make locating slot clamping in the horizontal direction so that locating slot
Position positions, and to be positioned to mainboard, and position offset will not occur for locating slot, so as to avoid mainboard in installation zero
Position offset occurs when component.
When motor is directed away from locating slot sliding, and the first friction plate and the second friction plate are detached from, internal messing ratchet machine
Structure run out of steam and stop drive shaft and flabellum rotation, internal messing ratchet mechanism can prevent shaft under the action of inertia after
Continuous rotation, to which bracing wire will not continue to that grip block is pulled to continue to slide so that the sliding position of grip block is accurate.Manually to operation
Platform both sides pull grip block, and grip block is made no longer to be pressed down against locating slot, to which locating slot can be under the action of the spring
Upward sliding.And during grip block slides, it can reversely pull bracing wire so that bracing wire loop line, and grip block passes through
Bracing wire drives shaft to rotate counterclockwise.Compared with the traditional way, it need not be positioned manually, it also need not be when installing parts
Mainboard is compressed.During grip block unclamps locating slot, the position of observable parts installation, grip block compresses locating slot
Shi Jinhang install, improve parts installation accuracy, compared with traditional installation, operating personnel do not have to continuously to parts into
Row installation can alleviate the fatigue that continuous installation parts are brought, improve the working efficiency of operating personnel.
Further, one end of two remotely located slots of grip block is fixed with vertical plate, and vertical plate is equipped with and operation console phase
The compression spring supported.When the first friction plate and the second friction plate are detached from, compression spring can push vertical plate to two Slideslip of operation console, vertically
Plate can be resetted with grip block to two Slideslip of operation console.
Further, frictional layer is equipped in the locating slot.Frictional layer avoids mainboard from being slided in locating slot so that mainboard exists
It is consolidated in locating slot.
Further, it is fixed with limit shaft below the locating slot.Limit shaft limits locating slot, and limit shaft
Locating slot can be supported so that installation parts when, locating slot be under pressure will not slide downward, ensure parts can
It is stably mounted on mainboard.
Further, the internal messing ratchet structure includes driving ratchet, outer ratchet, active pawl and check pawl, active
Ratchet is fixedly connected with output shaft, and outer ratchet is rotatablely connected with power seat, and outer ratchet is fixedly connected with shaft, and driving ratchet passes through
Active pawl is connected with check pawl.Under the action of the second friction plate, driving ratchet can rotate, and driving ratchet can pass through actively
Pawl and check pawl drive outer ratchet, when the first friction plate and the disengaging of the second friction plate, in active pawl and non-return ratchet
Under effect so that shaft can not be rotated further because of inertia.When shaft is rotated backward by the effect of bracing wire, in active pawl and
Under the action of check pawl and outer ratchet frictional force so that shaft will not be inverted quickly suddenly, enhance the stability of shaft.
Further, two grip blocks are equipped with guide groove, and the guide rod of silicone oil and guide groove cooperation is fixed on operation console.It is oriented to
Slot and guide rod are limited and are oriented to grip block, and grip block position offset in sliding process is avoided.
Further, the both sides of the locating slot be equipped with the first inclined-plane, two grip blocks close to one end of locating slot be equipped with
Second inclined-plane of the first inclined-plane cooperation.First inclined-plane and the second inclined-plane coordinate so that grip block, which facilitates, pushes down on locating slot.
