A kind of large scale and high-precision hot press
[technical field]
The utility model relates to hot press, particularly a kind of high-precision hot press of multiple size that is applicable to.
[background technology]
General hot press is mainly used in hot pressing such as FPC and LCD, FPC and PCB welding in the LCD production of liquid crystal displays operation.Existing LCD LCD manufacturer all must will use high precision hot press equipment, and performances the such as whether performance of hot-press equipment is stablized, thermal head size and precision directly have influence on production efficiency, product size and the qualification rate of institute's converted products.
Especially for LCD LCD manufacturer aborning in the production process of large scale (7 cun~10.4 cun) liquid crystal display module existing undersized hot press equipment can not be fit to the production needs of big-and-middle size liquid crystal display module.
[summary of the invention]
The purpose of this utility model is to provide a kind of large-size hot-press head, and hot pressing is respond well, bonding accurcy height, large scale high accuracy production in being applicable to.
In order to achieve the above object, a kind of large scale of the utility model and high-precision hot press are provided with workbench, the perpendicular man-machine interface of adorning of described workbench, in order to regulate and control each running parameter, and left and right sides workbench is provided with left and right sides pressure head, connect a pressure cylinder respectively and drive its operation up and down, it is characterized in that: described pressure head comprises that two up and down pressure heads cooperate pressure, and drives above-mentioned left and right sides workbench by a pair of leading screw.
Wherein, the heating piece of described pressure head comprises some grooves, and whole heating piece is divided into plurality of sections, comprises the independent temperature control of a temperature controller at every section, and the heating piece of described segmentation is connected with connecting plate by some nuts.
Wherein, described mariages thick stick comprises that Dual-motors Driving connects.
Wherein, described pressure head size adopts imported material to obtain by the special thermal treatment method greater than 200mm.
Advantage of the present utility model is:
1. owing to adopt two pressure heads to cooperate bi-motors to add the working method that the mariages thick stick drives two platforms, so it saves 2-3 second/sheet than machine of the same type in the past on the production cycle, output increases approximately 50% in the identical time, and the efficient raising is considerable.
2. owing to adopted the push-down head picking-up, last push-down head is the pattern of pressing together.Because the accumulated error of board machining accuracy and seaming chuck drop to minimum to the negative effect that shock loading produced of platform.
The thermal head size long (〉=200mm), thermal head adopts imported material by the special thermal treatment method, when guaranteeing the material highest hardness, at utmost controls the thermal deformation of material, and adopt high accuracy processing, make the control of thermal head working face precision be flatness ± below the 0.002mm.
4. because the heating piece adopts segmental structure, and segmentation adds thermal control, controls its temperature with temperature controller respectively on every section, like this whole piece pressure head (〉=200MM) the left, center, right temperature-difference can be controlled in below 3 ℃; And the heating piece of described segmentation is connected with connecting plate by some nuts, is convenient to regulate its degree of balance.

[specific embodiment]
As Fig. 1, shown in Figure 2, a kind of large scale and high-precision hot press 10 are provided with workbench 11, and described workbench 11 is erect a man-machine interface 12, in order to regulate and control each running parameter, and left and right sides workbench 11 is provided with left and right sides pressure head 111, connect a pressure cylinder 112 respectively and drive its operation up and down, wherein, described pressure head 111 comprises that two up and down pressure heads 1111,1112 cooperate pressing, and by pair of right and left motor 113 driving left and right sides screw mandrels 1131, thereby drive above-mentioned left and right sides workbench 11.
Wherein, described pair of right and left motor 113 comprises that pair of right and left screw mandrel 1131 drives connection.
Wherein, described push-down head 1111,1112 sizes that go up adopt imported material to obtain by the special thermal treatment method greater than 200mm.
Its operation principle is: driving 1131 drives of pair of right and left leading screw by pair of right and left motor 113 needs the hot pressing product to operate on workbench, push-down head 1112 holds up product, utilize pressure cylinder 112 to drive and go up push-down head 1111,1112 pressings together, and finish whole hot pressing.
The above person is the utility model most preferred embodiment only, is not to be used to limit scope of the present utility model, and all equivalences of being done according to the utility model claim change or modify, and are all the utility model and contain.
