In conjunction with Fig. 1, the course of work of 3D glass heat bender of the invention is: the electrical control cabinet first in starting pedestal 1,
The running parameter of each mechanism, starting water circulation mechanism 6, heat-generating units heating, nitrogen are set by the touch screen of control mechanism 2
Protection mechanism 7；Then the mold equipped with the glass to hot bending is placed on the work top of the first feeding mechanism 51, starting is set
Mold, the preheating mechanism 31 of the 1st station of molding assembly 3 is sent by the first feeding mechanism 51 by standby automatic operation mode,
Mold is sent into the designated position in the first pushing module 86, and the pushing of the first drive module 81 (servo motor) is opened by setup parameter
It is dynamic, the first upper die block 85 is pushed down on by the first link block 83 and is moved downward, when the lower surface of the first upper die block 85
When being bonded with die surface, the first adaptation module 84 is according to two plane contact situation the first upper die of adjust automatically blocks 85
It is bonded angle, during pushing fitting completely and meeting the setup parameter of the first drive module 81 (servo motor), heating is single
Member always heats mold, and the first adaptation module 84 is constantly bonded situation certainly according to the first upper die block 85 with mold
It is dynamic to adjust, until the setup parameter for meeting the first drive module 81 (servo motor), keeps and meet setting pressure maintaining duration
Afterwards, the first drive module 81 (servo motor) moves upwards reset, drives the first upper die block 85 to move upwards, leaves mold,
After the completion of reset, the second feeding mechanism 52 is transferred to the preheating of the 2nd station by the second pusher module (shift fork) promotion mold
Mechanism 31；Then it repeats the above steps, until mold passes sequentially through the preheating mechanism 31, shaping mechanism 32 and Xu Leng of each station
Mechanism 33 is pushed away mold by third feeding mechanism 53 after the Xu Leng mechanism 13 of the 14th station completes mechanism kinematic parameter
Enter the cooling body 41 to the 1st station of cooling component 4, third drive module 411 (cylinder) pushes the by setup parameter
Three upper die blocks 414 move downward, until 414 surface of third upper die block is bonded with mold, when holding meets setup parameter cooling
Between after, third drive module 411 (cylinder), which rises, to be resetted, drive third upper die block 414 to move upwards, after the completion of reset, the
Four feeding mechanisms 54 push mold to be transferred to the cooling body 41 of the 2nd station by the second pusher module (shift fork), in repetition
Step is stated, until mold is released cooling component 4 by the 4th feeding mechanism 54, the hot bending process of 3D glass is completed, 3D is prepared
Glass.
Preheating mechanism 31 in the molding assembly 3 in 3D glass heat bender and shaping mechanism 32 in the present invention are all made of
The structure for the heat pressing forming device 80 stated, servo motor structure is combined with adaptive structure: wherein servo motor can
The pushing displacement and down force pressure of first upper die block 85 are accurately controlled, and may be implemented to be segmented during pushing
Different displacement and down force pressure are exported, and by the way of segmentation output, export lesser displacement and pressure early period pushing,
Accurate control is realized in pressure required for exporting after Glass Transition and displacement, and can sufficiently improve each station work
Efficiency；Combining adaptive structure, the deformation that the first upper die block 85 under hot conditions and the first pushing module 86 can be generated
Compensating surface of the mold 90 respectively with the first upper die block 85 and the first pushing module 86 to guarantee 3D glass is had
Effect fitting, contact area is big, and the heat of heat-generating units can quickly be transmitted to the mold 90 of 3D glass, and make heat-bending glass
Uniform force guarantees molding flat degree；By the way that servo motor and adaptive structure to be combined, preferably play adaptive
The effect of structure, during the first upper die block 85 contacts pushing with mold 90, the first adaptation module 84 is automatically to first
Upper die block 85 is adjusted, during this servo motor can control the pushing of the first upper die block 85 displacement it is slow, and
Initial pressure is unsuitable too fast, and it is stuck to avoid result in the unexpected stress of the first adaptation module 84.
The flexible compensation mode of the accurate control and adaptive structure of servo motor is effectively combined in this programme, and it is existing
Technology uses opposite thinking, and the requirement of glass bending technique can be better achieved；Because operating ambient temperature can not reduce, deformation
It not can avoid, the prior art uses wolfram steel etc. using the thickness of heating module, the size for increasing pushing main shaft, heating module is increased
Mode reduces deformation and can not accomplish requirement of the flatness for meeting formed glass within 0.01mm, and processing cost, assembly
Technique requirement is high, overall cost is high；And in this programme it is not control and Reducing distortion, to the of less demanding of assembly technology,
Overall cost substantially reduces, and so as to prepare 3D glass with realizing extensive rate of good quality rate, 3D glass cover-plate is allowed to be widely applied
Become reality in mobile phone.
The 3 Zhong Xuleng mechanism 33 of molding assembly of 3D glass heat bender of the invention also uses adaptive structure, can increase
On the one hand contact surface makes Homogeneouslly-radiating, it is therefore prevented that and part heat dissipation is too fast to cause glass surface orange peel line or other deformation occur,
On the other hand it will appear stress release in glass molding cooling procedure, be also required to be pushed during cooling, prevent
The too fast release in part causes to shrink in pressure releasing process, by adaptive structure, increases contact surface, makes down force pressure
Uniformly, it is therefore prevented that the release of glass local stress is too fast surface irregularity occurs.
3D glass heat bender of the invention, by using servo electricity in the preheating mechanism and shaping mechanism in molding assembly
Machine and adaptive structure are combined, and allow 3D glass in molding big, the heated fast with the contact area of heating unit in the process
While also guarantee uniform force so that 3D glass is not easy situations such as fracture, damaged occur during the preparation process；It is same with this
When, adaptive structure is also used in Xu Leng mechanism, allows the 3D glass of forming can be with Homogeneouslly-radiating, and proof stress release is equal
It is even, it avoids the 3D glass of preparation from the case where surface irregularity occur, by the combination of these structures in molding assembly, strengthens
Control to 3D glass molding correlative factor, can also reduce the overall energy consumption of equipment while improving yields.
The above content is a further detailed description of the present invention in conjunction with specific preferred embodiments, and it cannot be said that
