Description

Technical Field

[0001] The invention relates to the technical field of copper foil production and processing, in particular to a slitting device for copper foil production. Background Art

[0002] Copper foil is a cathodic electrolytic material in the form of thin sheets, mainly made of electrolytic copper. Copper foil is widely used in many fields due to its excellent electrical conductivity, thermal conductivity and good ductility. It is mostly used in circuit boards. It is a thin, continuous layer of metal foil deposited on the base layer of the circuit board as a conductor of the PCB. Before the copper foil roll is used, it needs to be cut and processed so that the size of the copper foil meets the requirements of subsequent processing to reduce the waste of excess material after shearing.

[0003] When copper foil is slitting, the large roll of copper foil produced is cut into small rolls or sheets of specific width and length according to processing requirements. When the existing copper foil slitting equipment cuts the copper foil, the copper foil roll will produce uneven pits on the edge of the copper foil when it is slitting and roller transmission. The solid particles contained in the transmission roller also affect the flatness of the copper foil, affecting the subsequent copper foil winding and reducing the overall quality of the copper foil winding. Therefore, it is necessary to introduce a slitting equipment for copper foil production. Summary of the invention

[0004] The object of the present invention is to provide a slitting device for copper foil production to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0006] A slitting device for copper foil production, comprising a machine frame, a copper foil body and a central control platform, wherein a guide roller group is installed on the machine frame, the machine frame is connected to the copper foil body, a slitting mechanism is arranged on the top of the machine frame, a detection mechanism is installed on one side of the slitting mechanism, a receiving roller shaft is arranged at the bottom of the detection mechanism, the receiving roller shaft rewinds the slitting copper foil body, and the central control platform is connected to the machine frame;

[0007] The copper foil body passes through the guide roller group, the slitting mechanism, the detection mechanism and the receiving roller shaft in sequence. The slitting mechanism is used to slitting the copper foil body. The detection mechanism performs quality detection on the slitting copper foil body. The central control platform is used to control the guide roller group, the slitting mechanism and the detection mechanism.

[0008] The machine tool frame includes a supporting chassis, a discharge roller shaft is installed on the top of the supporting chassis, a copper foil body is placed on the discharge roller shaft, a positioning side plate is symmetrically arranged on one side of the supporting chassis, the supporting chassis is connected to the discharge roller shaft through an electric slide rail, one end of the discharge roller shaft is connected to a driving motor, and the other end of the discharge roller shaft is movably connected to the supporting chassis. By sliding the electric slide rail arranged horizontally, the spacing of the supporting chassis is adjusted, and the connection between one end of the discharge roller shaft and the supporting chassis is released at the same time, and the discharge roller shaft is quickly taken out, which is convenient for the staff to quickly place the copper foil body. The discharge roller shaft adopts an inflatable roller shaft, which speeds up the fixed positioning of the copper foil roll formed by winding the copper foil body, and improves the production efficiency of the staff.

[0009] A guide roller group is installed between the positioning side plate and the supporting chassis. The guide roller group includes a lifting cylinder and a guide roller shaft. The bottom of the lifting cylinder is connected to the machine tool frame. The top of the lifting cylinder is connected to the guide roller shaft through a bearing. The outer wall of the guide roller shaft is in contact with the copper foil body. The outer wall of the guide roller shaft is provided with a metal patch. The metal patch is connected to one end of the guide roller shaft through a grounding wire. When the copper foil body is rolled and unrolled, friction occurs inside to generate static electricity. Through the contact between the guide roller group and the copper foil body, the internal static electricity is grounded and guided out to avoid the influence of static electricity on subsequent processing, reduce the dust adsorbed on the surface of the copper foil body due to static electricity, and reduce the influence of dust on the rolling quality of the copper foil body. At the same time, according to the discharge speed of the copper foil body, the relative height of the guide roller shaft and the discharge roller shaft is adjusted to ensure the flat state of the copper foil body during the transmission process and avoid the problem of folding of the copper foil body.

[0010] The slitting mechanism is adjacent to the guide roller group and comprises a transverse guide rail. Both ends of the transverse guide rail are connected to the positioning side plates. An electric roller is installed on the transverse guide rail through an electric pulley.

[0011] The detection mechanism includes an electric roller, the outer wall of the electric roller is connected to the copper foil body, a positioning roller is arranged on one side of the electric roller, a leveling roller is installed on the side of the positioning roller away from the electric roller, a discharging roller is arranged in parallel on one side of the leveling roller, the positioning roller, the leveling roller and the discharging roller are all movably connected to the positioning side plate, and the surface of the electric roller is connected to the copper foil body.

[0012] The electric roller is located at the bottom of the electric roller. The copper foil body is transmitted to the electric roller after passing through the guide roller group. The guide roller group is located below the electric roller. The outer wall of the electric roller is provided with a plurality of annular patches. The central control platform is electrically connected to the annular patches on the electric roller. The copper foil body, the guide roller group and the electric roller form a slitting detection circuit. An ammeter is provided between the guide roller group and the connecting wire. The change of the contact area between the copper foil body and the electric roller affects the reading of the ammeter in the guide roller group. The electric roller is lowered to perform slitting processing on the copper foil body attached to the electric roller. The height of the guide roller group is adjusted according to the change of the ammeter, and the relative angle between the copper foil body and the electric roller is changed to ensure that the angle of the electric roller slitting processing of the copper foil body is uniform, thereby improving the processing quality of the copper foil body.

[0013] The positioning roller shaft is provided with an upper positioning roller and a lower positioning roller. The upper positioning roller is connected to the positioning side plate through a vertical slide groove. The two ends of the upper positioning roller are vertically provided with hydraulic rods. The surface of the lower positioning roller is flush with the surface of the electric rotating roller. In the positioning roller shaft, a pressure sensor is provided on the surface of the upper positioning roller. The upper surface of the copper foil body is sensed by the pressure sensor. The elongation dimension data in the hydraulic rod is transmitted to the central control platform to measure the thickness of the copper foil body after slitting. The detected thickness data is compared with the data in the slitting detection circuit to compare the change in the thickness of the copper foil body before and after slitting, and detect the overall quality.

[0014] The upper and lower positioning rollers in the positioning roller shaft are provided with conductive patches on their surfaces, and the surfaces of the upper and lower positioning rollers are connected to the upper and lower surfaces of the copper foil body, respectively. The flatness detection circuit is formed by the electric roller, the copper foil body and the positioning roller shaft. The upper and lower positioning rollers in the positioning roller shaft are electrically connected to the central control platform. The upper and lower positioning rollers are respectively connected to the upper resistance meter and the lower resistance meter. The upper resistance meter and the lower resistance meter transmit the measurement data to the central control platform for comparative analysis. The diameters of the upper and lower positioning rollers are the same. When the value of the upper resistance meter is large, it means that the contact area between the copper foil body and the upper positioning roller is small, and there is a downward depression on the copper foil body. When the value of the lower resistance meter is large, it means that the contact area between the copper foil body and the lower positioning roller is small, and there is an upward depression on the copper foil body. The problem on the surface of the copper foil body can be quickly judged, which is convenient for users to quickly trim.

[0015] The leveling roller shaft includes an upper leveling roller and a lower leveling roller, both of which are connected to a hydraulic cylinder, which is vertically arranged, and the central control platform controls the hydraulic cylinder to adjust the movement of the upper leveling roller and the lower leveling roller. According to the vertical resistance transmitted to the central control platform by the flatness detection circuit, the positions of the upper leveling roller and the lower leveling roller are adjusted. When the copper foil body has an upward depression, the lower leveling roller does not move, and the upper leveling roller is pressed down to squeeze and level the upper surface of the copper foil body. On the contrary, the lower leveling roller is raised to level according to the specific depression on the copper foil body, thereby further improving the quality of the copper foil slitting process.

[0016] The discharge roller is connected to the copper foil body. The copper foil body is rolled up onto the receiving roller after being transmitted by the discharge roller. A servo motor is arranged at one end of the receiving roller.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0018] The present invention forms a slitting detection circuit between a copper foil body, a guide roller group and an electric roller by arranging a guide roller group, a slitting mechanism and a detection mechanism. According to the change of the contact area between the copper foil body and the electric roller, the reading of the current meter in the guide roller group is affected, the height of the guide roller group is adjusted, and the relative angle between the copper foil body and the contact surface of the electric roller is changed, so as to ensure that the angle of the electric roller slitting the copper foil body is uniform, improve the quality of the copper foil body processing, reduce the setting of the transmission guide roller, reduce the manufacturing cost of the device, and facilitate the use of the device for processing copper foils of various sizes and thicknesses.

[0019] The present invention arranges a guide roller group, a slitting mechanism, a detection mechanism and a central control platform, and utilizes the conductivity of the copper foil to quickly detect and determine the state of the copper foil after slitting. The concave direction of the copper foil is obtained according to the resistance value of the current flowing through the copper foil slitting section. Subsequently, the deformation state of the copper foil is corrected and leveled, and the stress on the surface of the copper foil is quickly dispersed, so as to meet the demand for high-precision application of the copper foil and reduce the risk of cracks or breakage of the copper foil during use.

[0038] A guide roller group 2 is installed between the positioning side plate 103 and the supporting chassis 101. The guide roller group 2 includes a lifting cylinder and a guide roller shaft. The bottom of the lifting cylinder is connected to the machine tool frame 1. The top of the lifting cylinder is connected to the guide roller shaft through a bearing. The outer wall of the guide roller shaft is in contact with the copper foil body 6. The outer wall of the guide roller shaft is provided with a metal patch. The metal patch is connected to one end of the guide roller shaft with a grounding wire. When the copper foil body 6 is rolled and unrolled, friction occurs inside to generate static electricity. Through the contact between the guide roller group 2 and the copper foil body 6, the internal static electricity is grounded and guided out to avoid the influence of static electricity on subsequent processing, reduce the dust adsorbed on the surface of the copper foil body 6 caused by static electricity, and reduce the influence of dust on the rolling quality of the copper foil body 6. At the same time, according to the discharge speed of the copper foil body 6, the relative height of the guide roller shaft and the discharge roller shaft 102 is adjusted to ensure the flat state of the copper foil body 6 during the transmission process and avoid the problem of folding of the copper foil body 6.

[0039] The slitting mechanism 3 is adjacent to the guide roller group 2, and includes a transverse guide rail 301, both ends of which are connected to the positioning side plate 103, and an electric roller 302 is installed on the transverse guide rail 301 through an electric pulley. The electric roller 302 moves horizontally through the transverse guide rail 301, and adjusts its position according to the size requirements of the copper foil body 6. The vertical pole between the electric roller 302 and the electric pulley controls the lifting and lowering of the electric roller 302 to slit the copper foil body 6.

[0040] The detection mechanism 4 includes an electric roller 401, the outer wall of the electric roller 401 is connected to the copper foil body 6, a positioning roller 402 is arranged on one side of the electric roller 401, a leveling roller 403 is installed on the side of the positioning roller 402 away from the electric roller 401, a discharging roller 404 is arranged parallel to one side of the leveling roller 403, the positioning roller 402, the leveling roller 403 and the discharging roller 404 are all movably connected to the positioning side plate 103, and the surface of the electric roller 401 is connected to the copper foil body 6.

[0041] The electric roller 401 is located at the bottom of the electric hob 302. The copper foil body 6 is transferred to the electric roller 401 after passing through the guide roller group 2. The guide roller group 2 is located below the electric roller 401. The outer wall of the electric roller 401 is provided with a number of annular patches. The central control platform 7 is electrically connected to the annular patches on the electric roller 401. The copper foil body 6, the guide roller group 2 and the electric roller 401 form a slitting detection circuit. An ammeter is provided between the guide roller group 2 and the connection line. The change in the contact area between the copper foil body 6 and the electric roller 401 affects the reading of the ammeter in the guide roller group 2. The electric hob 302 is lowered to perform slitting processing on the copper foil body 6 attached to the electric roller 401. The height of the guide roller group 2 is adjusted according to the change in the ammeter to change the relative angle between the copper foil body 6 and the bonding surface of the electric roller 401.

[0042] The count of the current meter during normal and stable cutting is set as I, and the count measured by the current meter in real time is set as N;

[0043] When N is greater than 1, it indicates that the contact area between the electric roller 401 and the copper foil body 6 becomes larger, the diameter of the copper foil roll wound by the copper foil body 6 on the unwinding roller shaft 102 becomes smaller during the feeding process, and the angle between the copper foil body 6 and the electric roller 401 is reduced. It is necessary to control the guide roller group 2 to rise, raise the copper foil body 6, and expand the angle wound on the electric roller 401 to ensure that the slitting processing angle of the electric roller 302 is uniform;

[0044] When N is less than 1, it indicates that the contact area between the electric roller 401 and the copper foil body 6 becomes smaller, indicating that there are wrinkles or granular foreign matter on the copper foil body 6, which affects the contact between the copper foil body 6 and the electric roller 401, and the copper foil body 6 needs to be inspected and adjusted.

[0045] The positioning roller shaft 402 is provided with an upper positioning roller and a lower positioning roller. The upper positioning roller is connected to the positioning side plate 103 through a vertical slide groove. The two ends of the upper positioning roller are vertically provided with hydraulic rods.

In the positioning roller shaft 402, a pressure sensor is provided on the surface of the upper positioning roller. The upper surface of the copper foil body 6 is sensed by the pressure sensor, and the elongation dimension data in the hydraulic rod is transmitted to the central control platform 7 to measure the thickness of the copper foil body 6 after slitting. The detected thickness data is compared with the data in the slitting detection circuit, and the change in the thickness of the copper foil body 6 before and after slitting is compared to detect the overall quality.

The upper and lower positioning rollers are respectively connected to the upper resistance meter and the lower resistance meter. The upper resistance meter and the lower resistance meter transmit the measurement data to the central control platform 7 for comparative analysis. The diameters of the upper and lower positioning rollers are the same. When the value of the upper resistance meter is larger, it means that the contact area between the copper foil body 6 and the upper positioning roller is smaller, and there is a downward depression on the copper foil body 6. When the value of the lower resistance meter is larger, it means that the contact area between the copper foil body 6 and the lower positioning roller is smaller, and there is an upward depression on the copper foil body 6. The problems on the surface of the copper foil body 6 can be quickly judged, which is convenient for users to quickly repair.

[0047] Compare the values ​​of the upper resistance meter and the lower resistance meter. When the difference between the values ​​of the upper resistance meter and the lower resistance meter is too large, it means that the edge of the copper foil body 6 has a problem of warping after slitting. There are also problems such as hob wear or foreign matter blocking. The data is transmitted to the central control platform 7 to prompt the staff to perform maintenance and adjustment.

[0048] The leveling roller shaft 403 includes an upper leveling roller and a lower leveling roller, both of which are connected to a hydraulic cylinder, which is vertically arranged, and the central control platform 7 controls the hydraulic cylinder to adjust the movement of the upper leveling roller and the lower leveling roller. According to the vertical resistance transmitted to the central control platform 7 by the flatness detection circuit, the positions of the upper leveling roller and the lower leveling roller are adjusted. When the copper foil body 6 has an upward depression, the lower leveling roller does not move, and the upper leveling roller is pressed down to squeeze and level the upper surface of the copper foil body 6. On the contrary, the lower leveling roller is raised, and leveling is performed according to the specific depression on the copper foil body 6, so as to further improve the quality of the copper foil slitting process.

[0049] The discharge roller 404 is connected to the copper foil body 6. The copper foil body 6 is rolled up onto the receiving roller 5 after being transmitted by the discharge roller 404. A servo motor is provided at one end of the receiving roller 5 to control the rotation speed of the receiving roller 5 in real time.
