Automatically regulate pinch device
Technical field
The present invention relates to a kind of automatic adjusting pinch device.
Background technology
Before this device; portable computer protecting LCD screen film is by manually pasting; rubber roll on allied equipment mostly is angle and can not regulates; can not well be adapted to actual production; if well pressing; product surface there will be a large amount of bubbles to cause product bad, or for the production of device also because there being very high precision, price is all quite expensive.At electronic product by today of heavy demand, in order to meet market demands, have to expand the quantity of operating personal, also increased hand paste personnel's labour intensity simultaneously, require higher in or due to people's fatigue time, often just occur bad product, this just there will be does over again or scraps, and causes the decline of very large economic loss and product image.
Summary of the invention
The object of the invention is to overcome the deficiency that prior art exists, a kind of automatic adjusting pinch device is provided.
Object of the present invention is achieved through the following technical solutions:
Automatically regulate pinch device, comprise squeeze-film roller, the top of described squeeze-film roller is vertically fixed with line slide rail, on line slide rail, by linear bearing, clamping cylinder is installed, on described clamping cylinder, is fixed with air cylinder fixed plate, in described air cylinder fixed plate, S. A. is installed, rotation connecting element one end is sleeved on S. A., the angular contact bearing being loaded in the rotation connecting element other end is arranged on S. A., and mounting bracket is fixed on rotation connecting element, makes mounting bracket form a balancing seesaw.
Further, above-mentioned automatic adjusting pinch device, described angular contact bearing is fixed on S. A. by jam nut.
Further, above-mentioned automatic adjusting pinch device, the both sides in described air cylinder fixed plate are fixed with spring fixed block, and spring fixed block also fixes with mounting bracket.
The substantive distinguishing features of technical solution of the present invention and progressive being mainly reflected in:
The present invention produces a M.E by clamping cylinder to squeeze-film roller, adopt S. A., rotation connecting element, angular contact bearing and mounting bracket to produce an assistance force simultaneously, for squeeze-film roller, on tilt feeding platform, work, make this device that comparatively pulsation-free pressure can be provided, can not cause damage of product or occur air bubble problem, levelness for material conveying platform requires also significantly to lower simultaneously, save very large working accuracy, effectively reduce costs, simultaneously can resetting after finishing the work by compressing rubber roll under the effect of spring fixed block.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:
Fig. 1: organigram of the present invention;
Fig. 2 ~ 3: working state schematic representation of the present invention.
The specific embodiment
As shown in Figure 1, automatically regulate pinch device, comprise squeeze-film roller 8, the top of squeeze-film roller 8 is vertically fixed with line slide rail, on line slide rail, by linear bearing 9, clamping cylinder 10 is installed, on clamping cylinder 10, be fixed with air cylinder fixed plate 6, S. A. 5 is installed in air cylinder fixed plate 6, rotation connecting element 4 one end are sleeved on S. A. 5, the angular contact bearing 3 being loaded in rotation connecting element 4 other ends is arranged on S. A. 5, and angular contact bearing 3 is fixed on S. A. 5 by jam nut 2, mounting bracket 1 is fixed on rotation connecting element 4, make mounting bracket 4 form a balancing seesaw.Both sides in air cylinder fixed plate 6 are fixed with spring fixed block 7, and spring fixed block 7 also fixes with mounting bracket 1.
Wherein, the pressure of clamping cylinder 10 can regulate according to demand, and to guarantee that squeeze-film roller 8 is when the press mold, institute's press mold there will not be bubble.
embodiment 1
As shown in Figure 2, first clamping cylinder 10 can provide squeeze-film roller 8 one M.Es, when being tilted to the right appears in material conveying platform, thereby forcing the mounting bracket of rotation on connecting element to be tilted to the left, S. A. produces an assistance force left, make squeeze-film roller 8 laminatings more steady, and there will not be bubble, thereby more there will not be because platform inclination causes the uneven product that makes of pressure, the phenomenons such as bad or suitable evil idea occur.After then device work completes, after this device every task under the effect of spring fixed block is complete, can reset, carry out next working process.
embodiment 2
As shown in Figure 3, first clamping cylinder 10 can provide squeeze-film roller 8 one M.Es, when being tilted to the left appears in material conveying platform, thereby forcing the mounting bracket of rotation on connecting element to be tilted to the right, S. A. produces an assistance force left, make squeeze-film roller 8 laminatings more steady, and there will not be bubble, thereby more there will not be because platform inclination causes the uneven product that makes of pressure, the phenomenons such as bad or suitable evil idea occur.After then device work completes, after this device every task under the effect of spring fixed block is complete, can reset, carry out next working process.
The present invention produces a M.E by clamping cylinder to squeeze-film roller, adopt S. A., rotation connecting element, angular contact bearing and mounting bracket to produce an assistance force simultaneously, for squeeze-film roller, on tilt feeding platform, work, make this device that comparatively pulsation-free pressure can be provided, can not cause damage of product or occur air bubble problem, levelness for material conveying platform requires also significantly to lower simultaneously, save very large working accuracy, effectively reduce costs, simultaneously can resetting after finishing the work by spring fixed block effect rubber roll.
It is emphasized that: be only preferred embodiment of the present invention above, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
