Description

Technical Field

[0001] The utility model belongs to the technical field of electrolytic copper foil processing, and particularly relates to an automatic edge trimming device for electrolytic copper foil. Background Art

[0002] Electrolytic copper foil is an important material for manufacturing copper clad laminates (CCL), printed circuit boards (PCB), and lithium-ion batteries. The copper foil forming machine is used for the production of electrolytic copper foil. In the production of electrolytic copper foil, first, copper foil is formed on the surface of the cathode roller. After peeling, it enters the anti-oxidation tank through the roller system for chromium plating, and then passes through the upper liquid roller, acid squeezing roller, and subsequent drying and flattening before being wound into a copper foil master roll and sent to the next processing step. However, the copper foil directly peeled from the cathode roller has uneven thickness at the edges. If it is directly wound, it will cause various abnormal copper foil defects such as edge collapse and uneven anti-oxidation plating solution, which is not conducive to winding and subsequent process treatment. Therefore, before winding, the edges of the copper foil need to be slit, and these cut-off edge materials are generally wound by an edge trimming device.

[0003] Currently, in the drive mechanism of some edge trimming devices, the belt is a key transmission component. It is usually sleeved on the pulley and is responsible for transmitting power. However, since the tightness of the belt cannot be adjusted, as the use time increases, the belt will become loose and slip with the pulley, which will not only reduce the transmission efficiency but also may cause equipment failures. Summary of the Utility Model

[0004] The utility model provides an automatic edge trimming device for electrolytic copper foil, aiming to solve the problem that in the existing edge trimming device during use, due to the inability to adjust the tightness of the belt, as the use time increases, the belt will become loose and slip with the pulley as described in the above background art.

[0005] To solve the above problems, the utility model is realized as follows: An automatic edge trimming device for electrolytic copper foil, comprising: a mounting bracket, on which a support frame and a support seat are fixedly installed; an air shaft rotatably installed on the support seat, which is used for winding the edge materials of the electrolytic copper foil; a driving motor fixedly installed on the support frame, and a first pulley is fixedly sleeved on the output shaft of the driving motor; a second pulley fixedly sleeved on the air shaft; a belt sleeved on the first pulley and the second pulley; and a pressing mechanism assembled on the support seat for pressing the belt.

[0006] Preferably, the pressing mechanism includes: an electric push rod vertically and fixedly installed on the support base, a connecting plate extending towards the belt fixedly installed on the output rod of the electric push rod; a pressure sensor fixedly installed at the bottom of the connecting plate; a U-shaped plate fixedly installed at the bottom of the pressure sensor and opening downward, and a roller is rotatably installed in the U-shaped plate, and the roller is in contact with the belt.

[0007] Preferably, a vertically distributed limiting rod is fixedly installed at the top of the support base, and the limiting rod is slidably connected with the connecting plate.

[0008] Preferably, an air pipe adapter is provided at one end of the air shaft, and a controller signal-connected to the pressure sensor and the electric push rod is fixedly installed on the support base.

[0009] Preferably, a plurality of mounting holes are provided at the bottom of the mounting bracket, and all the plurality of mounting holes are used for mounting bolts.

[0010] Preferably, both the first pulley and the second pulley are made of stainless steel, and the mounting bracket is provided in an L shape.

[0011] Preferably, a triangular plate is fixedly installed on the mounting bracket, and the triangular plate is made of metal.

[0012] Compared with the related art, the electrolytic copper foil automatic edge trimming device provided by the present invention has the following beneficial effects:

[0013] Compared with the prior art, the electrolytic copper foil automatic edge trimming device provided by this solution can fix the paper tube for winding the edge material of the electrolytic copper foil through the use of the air shaft. After the fixing is completed, under the combined use of the drive motor, the first pulley, the second pulley and the belt, the air shaft can be driven to rotate, so that the paper tube on the air shaft can wind the edge material of the electrolytic copper foil. The edge trimming is relatively convenient. Through the combined use of the controller and the pressing mechanism, the tightness of the belt can be continuously detected. When the belt becomes loose due to long-term use, the pressing mechanism will apply a corresponding pressure to the belt to make it tighten on the first pulley and the second pulley, thereby avoiding slippage of the belt during use and not easily causing equipment failures, and the use effect is good. Through the limiting rod, it can prevent the connecting plate from shifting and shaking during movement, and improve the stability of the connecting plate during use.

[0019] Referring to "embodiments" herein means that the specific features, structures or characteristics described in connection with the embodiments can be included in at least one embodiment of this application. The phrase appears in various places in the specification and does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment mutually exclusive with other embodiments. Those skilled in the art will explicitly and implicitly understand that the embodiments described herein can be combined with other embodiments.

[0020] An embodiment of the present utility model provides an automatic edge trimming device for electrolytic copper foil, as Figures 1-3 shown. The automatic edge trimming device for electrolytic copper foil includes: a mounting bracket 1, on which a support frame 2 and a support seat 3 are fixedly installed; an air shaft 4 rotatably installed on the support seat 3, which is used for winding the edge material of the electrolytic copper foil; a drive motor 5 fixedly installed on the support frame 2, and a first pulley 6 is fixedly sleeved on the output shaft of the drive motor 5; a second pulley 7 fixedly sleeved on the air shaft 4; a belt 8 sleeved on the first pulley 6 and the second pulley 7; and a pressing mechanism assembled on the support seat 3 for pressing the belt 8.

[0021] In this embodiment, during use, the installation bracket 1 can be used to install the device at the corresponding position of the raw foil rack. Then, the paper tube for winding the waste electrolytic copper foil edge material is sleeved on the air shaft 4, and then air is filled into the air shaft 4, so that the air shaft 4 fixes the paper tube by expansion. After fixation, the waste electrolytic copper foil edge material is wound and fixed on the paper tube. Then, the driving motor 5 is started, and the driving motor 5 drives the first pulley 6 to rotate. The first pulley 6 drives the second pulley 7 to rotate through the belt 8, and the second pulley 7 drives the air shaft 4 to rotate, thereby realizing the winding work of the waste electrolytic copper foil edge material. The edge trimming is relatively convenient. During the long-term use of this device, the pressing mechanism continuously detects the tightness of the belt 8. When the belt 8 becomes loose due to long-term use, the pressing mechanism applies corresponding pressure to the belt 8 to make it taut on the first pulley 6 and the second pulley 7, thereby avoiding slippage of the belt 8 during use and not easily causing equipment failures, and the use effect is good. It should be noted that if it is worried that the waste electrolytic copper foil edge material will be torn during winding and it cannot be detected in time, two guide wheels can be set between the raw foil rack and this device, and a photoelectric sensor is set between the two guide wheels. In this way, when the waste electrolytic copper foil edge material is torn during winding, the photoelectric sensor will detect the change of the signal and transmit this information to the processor, thereby triggering an alarm device such as an audible and visual alarm. The audible and visual alarm and other alarm devices can be installed on the raw foil rack or other positions.

[0022] In a further preferred embodiment of the present invention, the pressing mechanism includes: an electric push rod 9 vertically and fixedly installed on the support base 3, a connecting plate 10 extending towards the belt fixedly installed on the output rod of the electric push rod 9; a pressure sensor 11 fixedly installed at the bottom of the connecting plate 10; a U-shaped plate 12 fixedly installed at the bottom of the pressure sensor 11 and opening downward, and a roller 13 is rotatably installed in the U-shaped plate 12, and the roller 13 is in contact with the belt 8.

[0023] In this embodiment, the pressing mechanism is used to press the belt 8. During use, the pressure sensor 11 continuously detects the downward pressure of the roller 13 on the belt 8. When the belt 8 becomes loose due to long-term use, the controller 17 automatically starts the electric push rod 9. The electric push rod 9 drives the connecting plate 10 to move vertically. The connecting plate 10 drives the pressure sensor 11 and the U-shaped plate 12 to move vertically. The U-shaped plate 12 drives the roller 13 to move vertically, so that the roller 13 presses the belt 8, thereby adjusting the loose belt 8 to a taut state, making the belt 8 not easily slip during use, and the use effect is good.

[0024] In a further preferred embodiment of the present utility model, a vertically distributed limiting rod 14 is fixedly installed on the top of the support base 3, and the limiting rod 14 is slidably connected to the connecting plate 10.

[0025] In this embodiment, through the limiting rod 14, it is possible to prevent the connecting plate 10 from shifting and shaking during movement, thereby enhancing the stability and reliability of the entire structure.

[0026] In a further preferred embodiment of the present utility model, an air pipe adapter 15 is provided at one end of the air shaft 4, and a controller 17 signal-connected to a pressure sensor and an electric push rod is fixedly installed on the support base 3.

[0027] In this embodiment, through the use of the air pipe adapter 15, it is possible to connect an external air source to support the expansion and retraction of the air shaft 4. Through the setting of the controller 17, it is convenient for the pressing mechanism to press the belt 8 according to the slack condition of the belt 8, so that the belt 8 can remain tight during long-term use, thereby ensuring the stability of the device during use.

[0028] In a further preferred embodiment of the present utility model, a plurality of mounting holes 16 are formed at the bottom of the mounting bracket 1, and the plurality of mounting holes 16 are all used for mounting bolts.

[0029] In this embodiment, through the use of the plurality of mounting holes 16, it is convenient for workers to fix the mounting bracket 1 to the corresponding position of the raw foil machine frame by using a plurality of bolts.

[0030] In a further preferred embodiment of the present utility model, both the first pulley 6 and the second pulley 7 are made of stainless steel, and the mounting bracket 1 is provided in an L shape.

[0031] In this embodiment, the first pulley 6 and the second pulley 7 made of stainless steel have high strength, corrosion resistance and stability, and have a good service life.

[0032] In a further preferred embodiment of the present utility model, a triangular plate 18 is fixedly installed on the mounting bracket 1, and the triangular plate 18 is made of metal.

[0033] In this embodiment, through the use of the triangular plate 18, the stability of the mounting bracket 1 during use can be improved, and the support strength can be increased.

[0034] In summary, compared with the related technologies, in this solution, through the use of the air shaft 4, the paper tube for winding the edge material of the electrolytic copper foil can be fixed. After the fixation, under the combined use of the drive motor 5, the first pulley 6, the second pulley 7, and the belt 8, the air shaft 4 can be driven to rotate, so that the paper tube on the air shaft 4 can wind the edge material of the electrolytic copper foil. The edge winding is relatively convenient. Through the combined use of the controller and the pressing mechanism, the tightness of the belt 8 can be continuously detected. When the belt 8 becomes loose due to long-term use, the pressing mechanism will apply corresponding pressure to the belt 8 to make it tightened on the first pulley 6 and the second pulley 7. Furthermore, the slippage of the belt 8 during use can be avoided, and equipment failures are not easily caused. The use effect is good. Through the limiting rod 14, the offset and shaking of the connecting plate 10 during movement can be prevented, and the stability of the connecting plate 10 during use can be improved.
