Description

Attrition process platform

Technical field

Liquid crystal panel processing equipment field is the utility model is related to, specifically for a kind of attrition process platform.

Background technology

Attrition process platform is the core component of liquid crystal panel chamfer grinding machine, in order to reach what is required in modern grinding technics High level of accuracy, existing attrition process platform largely employ DD motors and are controlled.

DD motors are also known as direct drive motor, and the high-torque of the product allows it to be directly connected with telecontrol equipment, from And such as retarder is eliminated, and gear-box, the bindiny mechanism such as belt pulley, therefore can just be called straight driving motor.Due to general The type motor is all configured with the encoder of high-res, therefore the product is reached the essence of a grade higher than generic servo Degree, and due to using mode is directly connected to, reducing the position error produced due to mechanical structure so that craft precision is protected Card.

But the original paper for once touching its internal precision after moisture gets rusty easily so as to seriously affect its precision, with this DD motors are expensive at present at the same time, once therefore the DD motors in machine table be damaged, then loss will be huge.

Existing attrition process platform is simply simple to be wrapped up DD motors wherein using a sealing structure, is only exposed The output shaft part of motor.But among actual production process, it is found by the applicant that there are others in such waterproof type Drawback and waterproof reliability is not high, its reason is：

In order to improve production work rate, existing grinder be substantially in 24 it is small when Non-intermittent ground working status Under, thus grinding table is substantially not at being ground among the environment of flushing water leaching all the time, it is if things go on like this tiny Droplet then can along between DD motor output shafts and annular seal space gap penetrate into, will necessarily if things go on like this cause the life of DD motors Rust, more seriously, due to that under DD the motors for a long time working status in super negative volume, can not be dissipated in its closing chamber Heat, overheats it will cause DD motors and triggers chain fault reaction in the course of time, if the then meeting again of the structure such as increase thermovent Weaken the sealing performance of annular seal space significantly.

Utility model content

The purpose of this utility model is that：Solve problem described above, there is provided a kind of attrition process platform, it can either be solved Certainly the sealing problem of DD motors can solve the heat dissipation problem of DD motors again at the same time.

The utility model is achieved through the following technical solutions：A kind of attrition process platform, it is characterised in that：Including waterproof cover, Be arranged on the DD motors in the middle part of waterproof cover, be fixedly mounted on DD motors top and can with DD revolution rotation seat, be arranged on Workbench above rotation seat, be set in the annular air cover of DD motors periphery, be set in outside the waterproof of annular air cover periphery Shell and the waterproof upper cover being located on waterproof case, rotation seat is through waterproof upper cover and is placed on the top of waterproof upper cover；

The cavity being internally provided with for accommodating pressure-air of the annular air cover, the top of annular air cover are equipped with extremely A few venthole, bottom is equipped with least one air inlet connected with external high pressure air-source；

The first air duct is equipped between the waterproof upper cover and annular air cover, between annular air cover and waterproof case Equipped with the second air duct, the first air duct is connected with the second air duct, and the second air duct is in communication with the outside.

Its principle is as follows：

Sealing structure between waterproof upper cover and waterproof case is Passive Defence, is first layer safeguard structure, can hinder Keep off the inside that the flushing water more than 99.9% flows into housing；

As shown in figure 4, the inside that annular air cover is arranged on waterproof case is Initiative Defense, it is second layer safeguard structure, It passes through extraneous source of high pressure air（Such as the device such as high-pressure pump）Pressure-air is pumped into annular air cover, forces air So that air pressure is flowed out after being lifted again after by the first air duct, the second air duct, its is main for outflow from venthole Purpose has two：First, residue is penetrated into the water of enclosure interior on one's own initiative by lasting, high flow rate gas flow channel Divide and vapor is taken away outside waterproof case by force, so as to thoroughly prevent all moisture close to the possibility of DD motors；

Second, heat that DD motors are given out is taken away by the flowing of lasting, high flow rate gas so as to reach to DD The effect of motor radiating.

In order to preferably implement this programme, following prioritization scheme is also provided：

Further, in order to further improve the junction of the waterproof effect of grinding table, the waterproof upper cover and rotation seat Equipped with sealing ring.

Further, for the scope that the flushing water for enabling to flow down on workbench quickly flows out grinding table, the waterproof The top of cover is the low domatic table top of the high surrounding in middle part.

Further, the venthole has ten, and each venthole is distributed on the surrounding at the top of annular air cover.

Than before for technology, the beneficial effects of the utility model are：By setting annular air inside waterproof case Cover, when it is not only able to force the moisture penetrated into inside waterproof case the outflow waterproof case can also take away DD motor operations at the same time The heat given out, so that having reached the sealing effect good to DD motors at the same time carries out DD motors lasting dissipate again Heat, considerably increases the security and reliability of DD motors.
