Automatic adjustment pinch device
Technical field
The present invention relates to one and automatically regulate 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; well can not be adapted to actual production; if can not well pressing; product surface there will be a large amount of bubble and causes 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 increase the labour intensity of hand paste personnel 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 very large economic loss and the decline of product image.
Summary of the invention
The object of the invention is the deficiency overcoming prior art existence, provide one automatically to regulate pinch device.
Object of the present invention is achieved through the following technical solutions:
Automatic adjustment pinch device, comprise squeeze-film roller, the top of described squeeze-film roller is vertically fixed with line slide rail, line slide rail is provided with compression cylinder by linear bearing, described compression cylinder is fixed with air cylinder fixed plate, described air cylinder fixed plate is provided with S. A., rotary mount one end suit on the rotary shaft, the angular contact bearing be loaded in the rotary mount other end is installed on the rotary shaft, and mounting bracket is fixed on rotary mount, makes mounting bracket form a balancing seesaw.
Further, above-mentioned automatic adjustment pinch device, described angular contact bearing is fixing on the rotary shaft by jam nut.
Further, above-mentioned automatic adjustment pinch device, the both sides in described air cylinder fixed plate are fixed with spring anchor block, and spring anchor block also fixes with mounting bracket.
Substantive distinguishing features and the progress of technical solution of the present invention are mainly reflected in:
The present invention produces a M.E by compression cylinder to squeeze-film roller, adopt S. A., rotary mount, angular contact bearing and mounting bracket to produce an assistance force simultaneously, work on tilt feeding platform for squeeze-film roller, make this device can provide comparatively pulsation-free pressure, damage of product can not be caused or occur air bubble problem, requirement for horizontality simultaneously for material conveying platform also significantly lowers, save very large working accuracy, effectively reducing costs, can reset by the carrying out after finishing the work by compressing rubber roll under spring anchor block effect simultaneously.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solution of the present invention is described further:

Fig. 2 ~ 3: working state schematic representation of the present invention.
Detailed description of the invention
As shown in Figure 1, automatic adjustment pinch device, comprise squeeze-film roller 8, the top of squeeze-film roller 8 is vertically fixed with line slide rail, line slide rail is provided with compression cylinder 10 by linear bearing 9, compression cylinder 10 is fixed with air cylinder fixed plate 6, air cylinder fixed plate 6 is provided with S. A. 5, rotary mount 4 one end is sleeved on S. A. 5, the angular contact bearing 3 be loaded in rotary mount 4 other end 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 rotary mount 4, mounting bracket 4 is made to form a balancing seesaw.Both sides in air cylinder fixed plate 6 are fixed with spring anchor block 7, and spring anchor block 7 also fixes with mounting bracket 1.
Wherein, the pressure of compression cylinder 10 can regulate according to demand, and to ensure that squeeze-film roller 8 is when press mold, institute's press mold there will not be bubble.
embodiment 1
As shown in Figure 2, first compression cylinder 10 can provide squeeze-film roller 8 one M.Es, when being tilted to the right appears in material conveying platform, S. A. forces the mounting bracket on rotary mount to be tilted to the left thus produces an assistance force left, squeeze-film roller 8 is allowed to fit more steady, and there will not be bubble, more there will not be because platform inclination causes pressure uneven thus to make product occur bad or along the phenomenon such as bad.After then device work completes, can reset after this device every task under the effect of spring anchor block is complete, carry out next working process.
embodiment 2
As shown in Figure 3, first compression cylinder 10 can provide squeeze-film roller 8 one M.Es, when being tilted to the left appears in material conveying platform, S. A. forces the mounting bracket on rotary mount to be tilted to the right thus produces an assistance force left, squeeze-film roller 8 is allowed to fit more steady, and there will not be bubble, more there will not be because platform inclination causes pressure uneven thus to make product occur bad or along the phenomenon such as bad.After then device work completes, can reset after this device every task under the effect of spring anchor block is complete, carry out next working process.
The present invention produces a M.E by compression cylinder to squeeze-film roller, adopt S. A., rotary mount, angular contact bearing and mounting bracket to produce an assistance force simultaneously, work on tilt feeding platform for squeeze-film roller, make this device can provide comparatively pulsation-free pressure, damage of product can not be caused or occur air bubble problem, requirement for horizontality simultaneously for material conveying platform also significantly lowers, save very large working accuracy, effectively reduce costs, can be resetted by the carrying out after finishing the work by spring anchor block effect rubber roll simultaneously.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
