Description

Technical Field

[0001] This invention belongs to the field of electronic material processing technology, and specifically relates to a copper foil edge material collection device. Background Technology

[0002] Copper foil is mainly used in electronic materials in the electronics industry. As a conductive material for copper-clad laminates and batteries, the thickness of the foil at the edges is uneven due to the distribution of electric field during the production process, which can cause quality problems during winding. Therefore, the edges must be cut off during winding to avoid product scrap.

[0003] Currently, a widely used method for collecting edge material employs a torque motor drive that powers a transmission air shaft. During edge material collection, the air shaft inflates, causing it to expand. To replace the edge material, the air shaft deflates, reducing its diameter to remove the edge material before it is rewound. However, because the expansion and contraction of the air shaft relies on an air chamber installed inside, powered by compressed air, an air compressor and air hoses are required. This design is inconvenient to install and has high operating costs. Furthermore, the air chamber is prone to leakage, necessitating replacement or maintenance, which also increases costs. Summary of the Invention

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this invention clearer and more understandable, the technical solutions of this invention will be further described in detail below with reference to the accompanying drawings.

[0026] like Figures 1-8 As shown, the copper foil edge material collection device provided by the present invention includes a support platform 1 and a first feeding unit, a pressing assembly, an edge material breakage detection unit, a second feeding unit, a crushing unit, and a ventilation assembly mounted on the support platform 1. The first feeding unit includes a feeding motor 20 and a conveyor belt assembly. The feeding motor 20 is fixedly mounted on the support platform 1 to drive the conveyor belt assembly to move. The pressing assembly is used to press the copper foil edge material 18 onto the conveyor belt assembly. The edge material breakage detection unit is used to detect whether the copper foil edge material 18 has broken. The second feeding unit is used to push the broken copper foil edge material 18. The crushing unit is used to crush the copper foil edge material 18 for recycling. The ventilation assembly is used to suck away the dust and debris of the crushed copper foil edge material 18 to avoid dust pollution to the produced copper foil.

[0027] When processing copper foil scrap 18, place the copper foil scrap 18 on the conveyor belt assembly, start the feeding motor 20 to make the conveyor belt assembly move, and then drive the copper foil scrap 18 towards the crushing unit. During this process, the clamping assembly can press the copper foil scrap 18 onto the conveyor belt assembly to prevent the copper foil scrap 18 from running off track or wrinkling during the conveying process.

[0028] The conveyor belt assembly includes a conveyor belt 6 and two pulleys 4. Both pulleys 4 are rotatably mounted on the support platform 1, and either pulley 4 is connected to the output shaft of the feeding motor 20. The conveyor belt 6 is wound around the two pulleys 4. After the feeding motor 20 is started, it can directly drive the pulley 4 connected to it to rotate, thereby driving the other pulley 4 and the conveyor belt 6 to move, conveying the copper foil edge material 18.

[0029] The clamping assembly includes a mounting bracket 22, a stud 24, a nut 23, two columns 26, two clamping springs 25, and two rubber rollers 21. The mounting bracket 22 is slidably mounted on the support platform 1. The stud 24 is movably mounted on the mounting bracket 22 and its bottom is fixedly inserted into the support platform 1. The nut 23 is threaded onto the top of the stud 24 and its bottom surface contacts the top surface of the mounting bracket 22. The two columns 26 are fixedly inserted into the mounting bracket 22. The two rubber rollers 21 are rotatably mounted on the bottom ends of the two columns 26 respectively. The two clamping springs 25 are respectively mounted on the two columns 26. The bottom end of the clamping spring 25 is fixedly connected to the support platform 1 and its top end is fixedly connected to the mounting bracket 22.

[0030] The rubber roller 21 provides pressure to press the copper foil edge 18 against the conveyor belt 6. When the pressure needs to be adjusted, the operator only needs to turn the nut 23. Since the bottom of the stud 24 is fixedly inserted into the support platform 1, turning the nut 23 causes relative rotation between the nut 23 and the stud 24. The nut 23 and the stud 24 are threaded together, so when the nut 23 rotates, it will move up and down along the axis of the stud 24. Since the bottom surface of the nut 23 is in contact with the top surface of the mounting frame 22, when the nut 23 moves downward, it will push the mounting frame 22 downward, thus driving the two columns 26 to move downward. This allows the rubber roller 21 to apply greater pressure to the copper foil edge 18 on the conveyor belt 6. Conversely, when the operator turns the nut 23 to make it rise, the mounting frame 22 will move upward under the action of the compression spring 25, thereby reducing the pressure of the rubber roller 21 on the copper foil edge 18.

[0031] The edge material breakage detection unit includes a detection support rod 36, a position adjustment block 38, a horizontal connecting rod 37, a sensor fixing block 40, and a foil breakage sensor 39. The detection support rod 36 is fixed on the support platform 1. The position adjustment block 38 is installed on the detection support rod 36 and its position is adjustable. The horizontal connecting rod 37 is installed on the position adjustment block 38. The sensor fixing block 40 is fixedly connected to the horizontal connecting rod 37. The foil breakage sensor 39 is installed on the sensor fixing block 40.

[0032] The foil breakage sensor 39 can detect whether the copper foil edge material 18 has broken. In some examples, the edge material breakage detection unit also includes an alarm device. When the copper foil edge material 18 is detected to be broken, the alarm device can issue an audible and visual alarm to alert the staff.

[0033] The second feeding unit includes a motor support plate 28, a crank-slider motor 29, a turntable 35, a crank 30, a second push rod 33, a slider 31, a slider guide groove 32, and a feeding block 34. The motor support plate 28 is fixed on the support platform 1. The crank-slider motor 29 is mounted on the motor support plate 28. The turntable 35 is connected to the output shaft of the crank-slider motor 29 via a keyway. The crank 30 is rotatably connected to the turntable 35. The second push rod 33 is rotatably connected to the crank 30. The slider guide groove 32 is set on the support platform 1. The slider 31 is connected to the second push rod 33 and is slidably embedded in the slider guide groove 32. The feeding block 34 is fixed to the bottom of the slider 31.

[0034] After the crank-slider motor 29 is started, it can drive the turntable 35 to rotate. Since the two ends of the crank 30 are rotatably connected to the turntable 35 and the second push rod 33 respectively, and the second push rod 33 is rotatably connected to the slider 31, and the slider 31 is slidably embedded in the slider guide groove 32, when the turntable 35 rotates, it can drive the slider 31 to reciprocate along the slider guide groove 32, and then push the broken copper foil edge material 18 through the feeding block 34, so that it continues to follow the conveyor belt 6.

[0035] The shredding unit includes a shredding motor 15, a cam 16, a first push rod 10, a push rod spring 14, an upper cutter 11, and a lower cutter 9. The shredding motor 15 is fixedly mounted on the support platform 1. The cam 16 is rotatably mounted on the support platform 1 and is connected to the output shaft of the shredding motor 15. The first push rod 10 is slidably mounted on the support platform 1 and its top surface is in close contact with the cam 16. The upper cutter 11 is fixedly mounted on the bottom end of the first push rod 10. The lower cutter 9 is fixedly mounted on the support platform 1 and is located below the upper cutter 11. The push rod spring 14 is sleeved on the first push rod 10. The top end of the push rod spring 14 is fixedly connected to the first push rod 10, and its bottom end is fixedly connected to the support platform 1.

[0036] After the crushing motor 15 is started, it can directly drive the cam 16 to rotate. The first push rod 10 is slidably installed on the support platform 1 and its top end is close to the cam 16. The first push rod 10 is also equipped with a push rod spring 14. Therefore, when the cam 16 rotates, it can drive the first push rod 10 to move up and down in conjunction with the push rod spring 14, thereby driving the upper cutter 11 to move up and down, intermittently cutting and crushing the copper foil edge material 18.

[0037] A waste chute 8 is provided on the support platform 1 at the lower cutter 9, and a chute support 7 is provided on the support platform 1. The chute support 7 is fixedly connected to the bottom surface of the waste chute 8. The cut and broken copper foil edge pieces 18 can slide out along the waste chute 8 and be collected for subsequent processing. The chute support 7 can support the waste chute 8 and prevent the copper foil edge pieces 18 from scattering due to vibration of the waste chute 8.

[0038] The exhaust system is used to remove the debris and dust from the shredded copper foil edge material 18, preventing dust contamination of the produced copper foil. The exhaust system includes a cutter guard 41, a scrap exhaust pipe 42, and a blower (not shown). The cutter guard 41 is installed on the support platform 1 at the upper cutter 11. One end of the scrap exhaust pipe 42 is installed at the end of the cutter guard 41 located at the outlet of the scrap chute 8, and the other end is connected to the outlet end of the blower (not shown).
