Description

Technical Field

[0001] The invention relates to the technical field of copper material processing equipment, in particular to an edge burr processing mechanism for copper foil rolling equipment. Background Art

[0002] Copper foil is an extremely thin copper sheet or copper strip, which usually has good electrical conductivity, thermal conductivity and ductility. Its thickness is generally between a few microns and hundreds of microns. In the electronics industry, copper foil is a key material for manufacturing printed circuit boards (PCBs). In multi-layer PCBs, copper foil serves as a conductive layer to provide a path for signal transmission between electronic components. The original copper material may have a certain degree of unevenness in thickness. Through calendering, the copper material can be gradually thinned under the pressure of the roller, and the thickness of the entire copper foil can be made more uniform. In the calendering process, the pressure of the roller can make the surface of the copper foil smoother and flatter. When the copper foil is cut from a larger copper material, if a shearing machine is used for cutting, the wear of the tool or the vibration during cutting may cause uneven edges. Especially when the tool has been used for a long time and the edge becomes blunt, the edge of the copper foil will be torn during the cutting process, thereby forming burrs.

[0003] However, the prior art still has the following defects when used specifically:

[0004] When there are burrs on the edge of the copper foil, the electrical performance will be unstable. The burrs will cause distortion of the local electric field and increase the possibility of corona discharge. At the same time, when the copper foil is used for interlayer connection of multi-layer circuit boards or mechanical assembly with other components, the burrs will hinder the close fit between the copper foil and other components, resulting in a loose connection. Therefore, the edge burrs should be polished after the copper foil is rolled. When using a belt grinder to polish the edge of the copper foil, if the copper foil does not have enough tension and is in a relaxed state, the copper foil will shake or bend during the polishing process, resulting in uneven contact between the grinding wheel or the sanding belt and the edge of the copper foil. Some burrs will not be polished, while other parts will be over-polished, which will reduce the polishing accuracy.

[0005] In view of this, the present invention proposes an edge burr processing mechanism for copper foil rolling equipment to compensate for and improve the deficiencies of the prior art. Summary of the invention

[0013] Furthermore, the lower positioning plate is located directly below the upper positioning plate, and the edges of the upper positioning plate and the lower positioning plate are located on the same horizontal plane as the surface of the belt grinder.

[0014] Furthermore, a monitoring and early warning mechanism is provided on the top of one end of the two support rods near the belt grinder, and the monitoring and early warning mechanism includes fixed blocks symmetrically fixedly connected to the tops of the two support rods, and monitoring rods are slidably connected inside the two fixed blocks, and the ends of the two monitoring rods away from the fixed blocks are located on the side of the side wall of the belt grinder, and the ends of the two monitoring rods away from the belt grinder are fixedly connected to the limiting plate, and the outer walls of the two fixed blocks near the limiting plate are fixedly connected with support springs, and the ends of the two support springs away from the fixed blocks are fixedly connected to the side wall of the limiting plate, and the outer walls of the top ends of the two fixed blocks near the support springs are fixedly connected with press-type sensors.

While protecting the copper foil, other safety accidents can be avoided. Compared with the existing warning method, real-time monitoring is not required, which is more energy-efficient.

[0029] Embodiments of the present invention

[0030] Please refer to Figures 1 to 8 As shown, an edge burr processing mechanism for copper foil rolling equipment includes a workbench 1 and a belt grinder 201, the belt grinder 201 is arranged above the top of the workbench 1, a fixed plate 2 is fixedly connected to the top of the workbench 1, the belt grinder 201 is fixedly connected to the outer wall of the fixed plate 2, the top of the workbench 1 is also fixedly connected to a support base 3, the top of the support base 3 is fixedly connected to a protective cover 301, and the top of the support base 3 is provided with an auxiliary deburring mechanism;

[0031] The auxiliary deburring mechanism includes a first conveying shaft 401 fixedly connected to the top of the support base 3, and a second conveying shaft 402 is also fixedly connected to the top of the support base 3 and one end away from the first conveying shaft 401. Two fixed frames 403 are symmetrically fixedly connected to the bottom of the top of the protective cover 301 and located above the support base 3. Adjusting rollers 404 are rotatably connected inside the two fixed frames 403. A cross bar 405 is also arranged between the two fixed frames 403. A vertical plate 406 is fixedly connected to the top of the protective cover 301, and a fixing belt 407 is fixedly connected to the middle of the top of the cross bar 405. A hook 408 is fixedly connected to the outer wall of the vertical plate 406, and one end of the fixing belt 407 away from the cross bar 405 passes through the inner wall of the top of the protective cover 301 and is plugged into the hook 408.

[0032] Among them, by adjusting the state of the copper foil between the two adjustment rollers 404, the tension of the copper foil is appropriate. The appropriate tension can keep the copper foil flat and stable in position. When the copper foil is in a tensioned state, the shape and position of its edge are relatively fixed, which helps the belt grinder 201 to accurately act on the burr position, avoiding the shaking or bending of the copper foil during the grinding process, making the contact between the belt grinder 201 and the edge of the copper foil more uniform, allowing the burrs to be evenly ground without over-grinding, thereby improving the grinding accuracy;

[0033] Preferably, a plurality of hooks 408 are evenly arranged on the outer wall of the vertical plate 406 in a vertical arrangement, and the plurality of hooks 408 are made of stainless steel. Two slide rails 501 are symmetrically fixedly connected to the inner wall of the fixed frame 403, and the outer walls of the two slide rails 501 are slidably connected to the sliding blocks 502, and the adjusting roller 404 is rotatably connected between the side walls of the two sliding blocks 502. The same number of slide rails 501 and sliding blocks 502 are arranged inside the two fixed frames 403, and the crossbar 405 is fixedly connected between the outer walls of the two sliding blocks 502;

[0034] Preferably, a grinding positioning assembly is provided at the top of the cross bar 405 near the side of the belt grinder 201, and the grinding positioning assembly includes two support rods 601 symmetrically fixedly connected to the top of the cross bar 405, and the two support rods 601 are respectively located on both sides of the belt grinder 201, and the bottom of the two support rods 601 near one end of the belt grinder 201 is fixedly connected with an upper positioning plate 602, and the two support rods 601 near one end of the belt grinder 201 are symmetrically fixedly connected with two brackets 603, and a lower positioning plate 604 is fixedly connected between the ends of the two brackets 603, and the two brackets 603 are fixedly connected with a positioning stopper 605 at one end near the lower positioning plate 604, and the lower positioning plate 604 is located directly below the upper positioning plate 602, and the edges of the upper positioning plate 602 and the lower positioning plate 604 are located in the same horizontal plane as the surface of the belt grinder 201;

[0035] Among them, since the burrs on the edge of the copper foil generally exceed the edges of the upper positioning plate 602 and the lower positioning plate 604, when the copper foil passes through the area of ​​the belt grinder 201, the protruding burrs on the edge will be polished away by the belt grinder 201, and the upper positioning plate 602 and the lower positioning plate 604 are used to protect the copper foil except the burrs to avoid excessive polishing, so that the polishing depth is controlled, and the ability of the copper foil to resist the polishing pressure is relatively stable, ensuring that only the burrs are removed without affecting the normal thickness of the edge of the copper foil;

[0036] Preferably, a monitoring and early warning mechanism is also provided on the top of one end of the two support rods 601 near the belt grinder 201, and the monitoring and early warning mechanism includes a fixed block 701 symmetrically fixedly connected to the top of the two support rods 601, and the two fixed blocks 701 are both slidably connected with a monitoring rod 702, and the ends of the two monitoring rods 702 away from the fixed blocks 701 are both located on one side of the side wall of the belt grinder 201, and the ends of the two monitoring rods 702 away from the belt grinder 201 are fixedly connected to a limiting plate 703, and the two The outer wall of each fixed block 701 close to the limiting piece 703 is fixedly connected to a support spring 704, and one end of the two support springs 704 away from the fixed block 701 is fixedly connected to the side wall of the limiting piece 703, and the outer wall of the top of the two fixed blocks 701 close to the support spring 704 is fixedly connected to a press sensor 705, and a suction fan 801 is installed on the top of the protective cover 301, and a dust suction pipe 802 is fixedly connected to the outer wall of the suction fan 801, and the bottom opening of the dust suction pipe 802 is located above the upper positioning plate 602;

[0037] Among them, when the vibration amplitude of the sanding belt of the belt grinder 201 is too large, its side wall will contact with the end of the monitoring rod 702. By pushing the monitoring rod 702, the monitoring rod 702 can slide inside the fixed block 701, and at the same time cooperate with the limit plate 703 to stretch the support spring 704. As the monitoring rod 702 is subjected to a large pushing force, the limit plate 703 finally contacts with the press-type sensor 705. By pressing the press-type sensor 705, the press-type sensor 705 generates an electrical signal and synchronously transmits it to the controller of the belt grinder 201, so that the belt grinder 201 stops rotating, which plays a role of early warning, making it convenient for the staff to repair and replace the sanding belt of the belt grinder 201, protecting the copper foil while avoiding other safety accidents.

[0038] The following are the complete usage steps and working principles of the above embodiment:

[0039] When the device is used, the copper foil needs to be ground for edge burrs after calendering. The copper foil is first passed from below the surface of the first conveying shaft 401, then passed above the surface of the adjusting roller 404 near the first conveying shaft 401, then passed above the surface of the adjusting roller 404 near the second conveying shaft 402, and finally passed from below the surface of the second conveying shaft 402, so that the copper foil can be conveyed above the top of the support base 3, and the edge burr grinding work is completed in the copper foil conveying process in cooperation with the belt grinder 201. It is suitable for grinding the edge burrs of a large number of copper foils. By setting the protective cover 301, the edge burrs of the copper foil can be protected during the grinding process, so as to avoid sudden debris splashing and the breakage of the belt of the belt grinder 201 causing physical harm to the staff;

[0040] When the copper foil is located between the two adjusting rollers 404 above the surface, the staff decides whether to adjust the height of the two adjusting rollers 404 synchronously according to the state of the copper foil between the two adjusting rollers 404 before the formal grinding begins. When the copper foil is being conveyed, the tension is not adjusted in place, so that the copper foil is in a relaxed state in the middle section between the two adjusting rollers 404. First, the top of the fixing belt 407 is removed from the hook 408 and separated, and then the fixing belt 407 is gradually lifted up, so that the fixing belt 407 pulls up the cross bar 405 to move upward, so that the cross bar 405 can be lifted up. The sliding blocks 502 symmetrically arranged on both sides slide upward synchronously on the outer wall of the slide rail 501. The sliding of the sliding blocks 502 on the outer wall of the slide rail 501 can help the adjusting rollers 404 to remain stable during the rising and falling processes, and always be in the same sliding path, so as to avoid the shaking of the adjusting rollers 404 affecting the grinding effect of the copper foil burrs. The lifting height is matched with the first conveying shaft 401 and the second conveying shaft 402, so that the copper foil in the relaxed state in the middle section is straightened, so that the copper foil between the two adjusting rollers 404 is in a horizontal state, which makes it easier for the edge of the copper foil to contact and grind with the sanding belt grinder 201. Finally, the top of the fixing belt 407 is plugged into the hook 408 at the corresponding position to complete the fixing of the height of the two adjusting rollers 404. By adjusting the state of the copper foil between the two adjusting rollers 404, the tension of the copper foil is appropriate. The appropriate tension can keep the copper foil flat and stable in position. When the copper foil is in a tensioned state, the shape and position of its edge are relatively fixed, which helps the sanding belt grinder 201 to accurately act on the burr position, avoiding the phenomenon of shaking or bending of the copper foil during the grinding process, making the contact between the sanding belt grinder 201 and the edge of the copper foil more uniform, so that the burrs can be evenly polished, and over-polishing will not occur, thereby improving the grinding accuracy;

[0041] The staff will advance the copper foil between the two adjusting rollers 404 through the gap between the upper positioning plate 602 and the lower positioning plate 604, and cooperate with the upper positioning block 605 to make the edge of the copper foil and the edges of the upper positioning plate 602 and the lower positioning plate 604 on the same horizontal plane. Since the burrs on the edge of the copper foil generally exceed the edges of the upper positioning plate 602 and the lower positioning plate 604, when the copper foil passes through the area of ​​the belt grinder 201, the protruding burrs on the edge will be polished away by the belt grinder 201, and the upper positioning plate 602 and the lower positioning plate 604 are used to protect the copper foil except the burrs to avoid excessive polishing, so that the polishing depth is controlled, the ability of the copper foil to resist the polishing pressure is relatively stable, and it is ensured that only the burrs are removed without affecting the normal thickness of the edge of the copper foil, so that the polishing effect of the burrs is improved;

[0042] In addition, by arranging monitoring rods 702 on both sides of the sanding belt of the sanding belt grinder 201, and the two monitoring rods 702 are kept at a certain distance from the side walls of the sanding belt of the sanding belt grinder 201, when the sanding belt of the sanding belt grinder 201 is excessively worn or abnormal conditions occur, especially after the sanding belt is excessively worn, a large amount of sand particles will fall off. Since the degree of wear in different areas of the sanding belt surface may be inconsistent, the sand particles will fall off unevenly. One side of the sanding belt will fall off more, while the other side will fall off relatively less, which will cause the sanding belt to be unbalanced during operation. When the sanding belt is unbalanced, a difference in centrifugal force will be generated during high-speed rotation, which will easily cause the sanding belt of the sanding belt grinder 201 to jump laterally during rotation. During this period, the sanding belt of the sanding belt grinder 201 jumps too much, and its side wall will contact the end of the monitoring rod 702. By pushing the monitoring rod 702, the monitoring rod 702 can slide inside the fixed block 701, and at the same time cooperate with the limiting piece 703 to stretch the supporting spring 704. As the monitoring rod 702 is subjected to a large pushing force, the limiting piece 703 finally contacts the pressing sensor 705. By pressing the pressing sensor 705, the pressing sensor 705 generates an electrical signal and transmits it to the controller of the belt grinder 201 synchronously, so that the belt grinder 201 stops rotating, which plays a role of early warning. Compared with the existing early warning method, real-time monitoring is not required, so it is more energy-efficient, and an early warning is issued only when the sand belt of the belt grinder 201 jumps, so that the accuracy of the early warning is improved, which is convenient for the staff to repair and replace the sand belt of the belt grinder 201, while protecting the copper foil and avoiding other safety accidents.

[0043] Since fine dust is generated during the grinding of the burrs on the edge of the copper foil, a suction fan 801 is provided in combination with a dust suction pipe 802, and the bottom opening of the dust suction pipe 802 is located above the upper positioning plate 602, so that the purpose of grinding the burrs and collecting fine dust can be achieved, thereby improving the surrounding environment when the device is used.

[0044] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
