In the automated production line, the press roll 300 is located at the upper side of the conductive roll 400, and the copper film 500 with liquid passes between the conductive roll 400 and the press roll 300, and bypasses the conductive roll 400. The copper film 500 with liquid on the left side in the drawing passes through the press roller 300 and the conductive roller 400 to form a copper film without liquid.
In the closed-loop control system, the pressure sensor 250 is connected with a controller, the pressure sensor 250 is arranged at the joint of the sliding block and the cylinder 210, the controller is connected with the proportional valve 120, the proportional valve 120 is connected with the electromagnetic valve 110 and the cylinder 210, and the controller controls the opening degree of the proportional valve 120 so as to regulate the pressure of the cylinder 210.
Specifically, in the production process, fixed technological parameters are selected, and the electric appliance control part starts to work after the corresponding pressure value is input. When the pressure changes, the output of the pressure sensor 250 changes, and the controller sends out a command to control the pressure born by the pressure sensor 250 to be automatically adjusted between the upper limit and the lower limit of the set value through the adjustment of the opening degree of the proportional valve 120. The precise range between the upper and lower limits of the adjustment is determined by the accuracy of the sizing of the proportional valve 120 and the pressure sensor 250, and the specific data range is not limited herein.
In the present embodiment, the slider includes an upper slider 231 and a lower slider 232, the upper slider 231 is located at the upper side of the lower slider 232, and the pressing roller 300 is sleeved inside the lower slider 232. Specifically, the pressing roller 300 is fixed on a slider (specifically, the lower slider 232), and the pressing roller 300 rotates with the slider as a bearing. In the production process, the upper end of the sliding block is connected with the air cylinder 210, and the air cylinder 210 pushes the sliding block to slide up and down, so that the press roller 300 is driven to be close to or far away from the conductive roller 400.
In this embodiment, the upper slider 231 and the lower slider 232 are both disposed inside the outer frame 201, the guide post 202 in the vertical direction is disposed in the outer frame 201, and the upper slider 231 and the lower slider 232 are both sleeved on the guide post 202 through the linear bearing 204. The guide pillar 202 is fixed with the outer frame 201 into a whole through the matching holes and screws on the outer frame 201, so that the parallelism between the press roller 300 and the conductive roller 400 is ensured, the positioning and guiding functions of the upper sliding block 231 and the lower sliding block 232 are achieved, the upper sliding block 231 and the lower sliding block 232 slide up and down in the same direction through the accurate guiding of the guide pillar 202, and further, the conductive roller 400 and the press roller 300 are ensured to always keep central overlapping in the opening and closing process.
Preferably, a limit boss 203 is provided in the outer frame 201, an upper slider 231 is located on the upper side of the limit boss 203, and a lower slider 232 is sleeved in the outer frame 201 below the limit boss 203. The width of the upper slider 231 is greater than the width of the lower slider 232, so that the limiting boss 203 limits the sliding position of the upper slider 231. The pressing force and the contact area of the pressing roller 300 to the conductive roller 400 can be adjusted by the limit boss 203.
As shown in fig. 2, the outer side of the press roller 300 is provided with an inner envelope 320 and an outer envelope 310, and the hardness of the inner envelope 320 is smaller than that of the outer envelope 310. Because the press roller 300 adopts the double-layer encapsulation technology with soft inside and hard outside, the press roller 300 can effectively buffer under the conditions of jumping when the press roller 300 is touched, the thickness change of the copper film 500 and the like, and the contact area of the press roller 300 and the conductive roller 400 is kept consistent, thereby ensuring that the copper film 500 is consistent in stress point, stress surface and stress direction at the moment of being compressed by the two rollers.
Specifically, the material of the inner envelope 320 is polyurethane PU elastic material, and the hardness is (HA 40-45); the material of the outer envelope 310 is ethylene propylene diene monomer rubber, and the hardness is (HA 65-70). The contact area variation due to deformation can be adaptively counteracted in the case that the relative misalignment occurs during operation while both the press roller 300 and the conductive roller 400 are within the form and position tolerance.
As shown in fig. 1, 3 and 4, a diagonal block 240 is provided between the upper slider 231 and the lower slider 232, the upper surface of the diagonal block 240 is connected to the upper slider 231, the lower surface thereof is connected to the lower slider 232, and the upper slider 231 and the lower slider 232 are integrally connected through the diagonal block 240. The adjustment of the pressure and the contact area between the press roller 300 and the conductive roller 400 is further realized by adjusting the distance between the upper slider 231 and the lower slider 232 by adjusting the front and rear positions of the inclined block 240, so that the pressure consistency adjustment of the copper film 500 at different positions in the width direction is satisfied.
In this embodiment, the adjusting bolt 244 is connected to the center shaft hole 242 of the swash block 240 through the center shaft 243, and the position of the swash block 240 is adjusted through the adjusting bolt 244 and the center shaft 243.
Preferably, the upper surface of the swash block 240 is inclined, the lower surface thereof is horizontal, and the rear side of the swash block 240 is connected to the adjusting pin 244. The longitudinal section of the whole swash block 240 is in an I shape, wherein the upper half or the lower half of the swash block 240 is separately formed into a deformed structure of a dovetail groove, and the swash block 240 in the shape is convenient for production and processing, and simultaneously, the front and rear positions of the swash block 240 are more convenient to adjust.
By adjusting the front and rear positions of the inclined block 240, the up and down positions of the lower slider 232 can be adjusted, and thus the up and down positions of the press roller 300 can be adjusted.
During the specific operation of the swash block 240 position adjustment: the pressure of the pressure sensor 250 is set according to the process parameters, and the pressure is automatically regulated by the control system after the automatic mode is started. And then the positions of the two oblique blocks 240 are adjusted according to the stress condition of the copper film 500, and finally the copper film 500 is uniformly stressed in the width direction and stable in tension partition.
As shown in fig. 5 and 6, a link 211 is provided at the lower end of the cylinder 210, and the link 211 is connected to the slider through a buffer assembly 220. Preferably, the buffer assembly 220 includes a connection housing 221, and the pressure sensor 250 is disposed within the connection housing 221. The upper end of the connection cover 221 is fixedly connected (preferably, screw-fixedly connected) with the cylinder 210, and the side surface of the connection cover 221 is sleeved on the contour screw 222 and slides up and down along the contour screw 222, and the contour screw 222 is fixedly connected with the slide block.
In the buffer assembly 220, the limiting height of the equal-height screw 222 enables the connecting cover 221 to have an upper and lower movable space, so that the measurement accuracy of the pressure sensor 250 is guaranteed. Specific: when the cylinder 210 presses down the connecting rod 211, the connecting cover 221 contacts with the pressure sensor 250, but there is no contact (distance is L) between the connecting cover and the upper slider 231, the pressure sensor 250 bears all the pressure, and when the pressure changes, the pressure sensor 250 can accurately reflect the changing size; when the cylinder 210 pulls the link 211 to retract, the distance between the connection cap 221 and the upper slider 231 increases to L1, and the connection cap 221 is separated from the pressure sensor 250 (distance L2), so that the pressure sensor 250 is not subjected to any external force, and the reading of the pressure sensor 250 is zero.
As shown in fig. 7, the principle of the present invention for realizing separation of the pressing roller 300 and the conductive roller 400 is as follows:
when the press roller 300 and the conductive roller 400 are required to stretch out and penetrate the belt, a reversing signal is required to be output to the electromagnetic valve 110, and a distance H is required to stretch out between the press roller 300 and the conductive roller 400 under the action of the air cylinder 210. Since all parameters are not modified, after the solenoid valve 110 controls the cylinder to be re-pressed, the basic parameters between the press roller 300 and the conductive roller 400 are kept unchanged, so that the follow-up work is ensured to be normally carried out, and various parameters are not required to be adjusted.
As shown in fig. 8 to 10, the adjustment principle of the contact area of the copper film 500 by the press roller 300 and the conductive roller 400 according to the present invention is:
The center distance Z between the press roller 300 and the conductive roller 400 during normal operation, the contact arc length Y between the press roller 300 and the conductive roller 400, and the dimension X and the contact arc length Y between the inner envelope 320 of the press roller 300 after deformation of the bearing surface are relatively stable. When the center distance between the press roller 300 and the conductive roller 400 becomes larger z+ or smaller Z-, the deformation amount of the inner envelope 320 is larger than that of the outer film 310 because the hardness of the inner envelope 320 is softer than that of the outer film 310, that is, the size x+ or X "of the deformed stress surface of the inner envelope 320 is larger than the change of the contact arc length Y value, so that the deformation amount caused by the form and position tolerance between the press roller 300 and the conductive roller 400 is transferred to the inner envelope 320 to the maximum extent, thereby ensuring that the contact arc length Y value between the press roller 300 and the conductive roller 400 is unchanged to the maximum extent.
It will be understood that modifications and variations will be apparent to those skilled in the art from the foregoing description, and it is intended that all such modifications and variations be included within the scope of the following claims.
While the invention has been described above with reference to the accompanying drawings, it will be apparent that the implementation of the invention is not limited by the above manner, and it is within the scope of the invention to apply the inventive concept and technical solution to other situations as long as various improvements made by the inventive concept and technical solution are adopted, or without any improvement.
