Description

Technical Field

[0001] The present invention relates to the technical field of copper foil transportation, and in particular to an automatic transportation device for PCB circuit board copper foil. Background Art

[0002] Printed circuit boards (PCBs) are important electronic components and serve as the electrical interconnection carriers for electronic components. They feature small footprints and high circuit reliability, making them widely used in the processing of various electronic devices. However, copper foil roll conveying in PCB manufacturing lines has the following drawbacks: The copper foil roll can tilt, causing collision and friction with the conveying device, affecting the quality of the copper foil. Furthermore, this tilt can easily lead to incomplete circuit printing during subsequent processing, and manual adjustment increases the operator's workload. Copper is one of the most important raw materials in modern industry. During the copper processing, copper ingots are dissolved and then drawn through a die to form copper foil strips with a certain width and thickness. In order to meet the use requirements, the copper foil strips need to go through multiple procedures such as pressing and polishing to meet the use requirements. The copper foil strips are wound into layers of copper foil rolls through a winding device. The copper foil rolls are moved to other processes as a whole and are processed in sequence to meet the various performance requirements of the printed circuit board. In the existing technology, the copper foil rolls are usually moved by manual labor using a trolley. This movement method is not only laborious but also has low work efficiency. In addition, the copper foil rolls can only be transported on flat ground and cannot be transported vertically. When transporting in the height direction, heavy copper foil rolls cannot be transported by conveyor belts.

[0003] Due to structural design defects, existing automatic transport equipment for PCB circuit board copper foil has problems such as how to transport heavy copper foil rolls from bottom to top and how to prevent the copper foil rolls from tilting and unwinding during transportation.

[0020] The present invention provides an automatic transport device for PCB copper foil, which has the following beneficial effects:

[0021] 1. This automatic transport device for PCB copper foil uses an electric cylinder to drive the pushing component close to the first motor. The anti-unwinding mechanism is equipped with a copper foil roll, which is pushed to the lower position of the inner side of the fixed component. The surface of the fixed component engages with the surface of the anti-unwinding mechanism. The first motor drives the lead screw to rotate. By changing the inclination angle of the lead screw, the movement direction of the copper foil roll is controlled. The lifting force of the thread pushes the anti-unwinding mechanism to move diagonally upward, solving the problem of how to transport heavy copper foil rolls from bottom to top.

[0022] 2. This automatic transport device for PCB copper foil has one end of a bent rod extending to a position near the end face of the anti-unwinding mechanism, and the bent rod supports the push block. The electric cylinder drives the magnetic rod close to the first motor, causing the anti-unwinding mechanism to roll above the sliding plate and be fixed below the surface of the lead screw. During lifting, the surface of the anti-unwinding mechanism slides on the surface of the chute, thereby preventing manpower from carrying the heavy copper foil.

[0023] 3. The automatic transport device for PCB copper foil has a copper foil roll placed inside the meshing assembly. The pushing assembly pushes the meshing assembly to the position of the gate hoist. The gate hoist drives the threaded rod to screw into the inner side of the rotating assembly, so that the rotating assembly and the slide are tightly fixed. The meshing assembly protects the copper foil roll, solving the problem of how to prevent the copper foil roll from tilting and unwinding during transportation.

[0024] 4. The automatic transport device for PCB copper foil has the surface of the rotating disk embedded in the gap between the sliding plates. The connecting cover is pushed to the axis position of the gate hoist, and the threaded rod is screwed into the inner side of the internal threaded barrel, so that the internal threaded barrel and the slide are fixed. When the slide moves obliquely upward, the connecting cover and the internal threaded barrel are rotated, so that the sliding friction of the meshing barrel is converted into rolling friction, which effectively reduces the energy consumption of the transport device.

[0025] 5. The automatic transport device for PCB circuit board copper foil has a sliding connection between the surface of the gate and the limit platform near the slide slot, so that the gate pushes the meshing cylinder to roll upward. The meshing between the tooth surfaces makes the meshing cylinder more stable and less likely to shake when it moves obliquely upward. This replaces the existing technology of using a friction belt to drive the copper foil tape to move. The copper foil tape is too heavy and easily slides and collides with the surface of the friction belt. The transport device effectively prevents the copper foil tape from being damaged and unwound during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] The anti-unwinding mechanism 5 is used to fix the heavy copper foil roll. The surface of the anti-unwinding mechanism 5 engages with the inner side surface of the fixing component 41 through the tooth surface.

By changing the inclination angle of the screw rod 44, the moving direction of the copper foil roll is controlled, and the lift force of the thread pushes the anti-unwinding mechanism 5 to move obliquely upward, thereby solving the problem of how to transport heavy copper foil rolls from bottom to top.

The pushing component 46 includes a second motor 461, the surface of the second motor 461 is fixedly connected to the position of the surface of the base 1 near the electric cylinder 45, the second motor 461 is a hollow motor, and the inner side surface of the electric cylinder 45 is slidably connected to the magnetic rod 462, the end of the magnetic rod 462 away from the electric cylinder 45 is fixedly connected to the bent rod 463, and the end of the bent rod 463 away from the magnetic rod 462 is fixedly connected to the push block 464.

[0043] When in use, the anti-unwinding mechanism 5 rolls above the sliding plate 414, and the second motor 461 is a hollow magnetic levitation motor. The second motor 461 drives the magnetic rod 462 to rotate through magnetic force, so that the bent rod 463 is close to the sliding plate 414, and one end of the bent rod 463 extends to the position close to the end face of the anti-unwinding mechanism 5, and the bent rod 463 supports the push block 464.

When lifting, the surface of the anti-unwinding mechanism 5 slides on the surface of the slide groove 412, thereby preventing manpower from carrying heavy copper foil.

The rotating shaft of the output end of the first motor 43 is fixedly connected to the screw rod 44. The pushing component 46 pushes the copper foil roll to the inner side surface of the fixed component 41, and the screw rod 44 drives the copper foil roll to move obliquely upward through the lift of the thread; the top of the base 1 is fixedly connected to the electric cylinder 45 near the side wall 42, and the output end of the electric cylinder 45 is slidably connected to the surface of the pushing component 46. The bottom of the fixed component 41 is fixedly connected to the top of the base 1, and the anti-unwinding mechanism 5 includes a slide 51. The inner side surface of the slide 51 is connected to the surface of the screw rod 44 through a thread. The lower position of the inner side surface of the slide 51 is fixedly connected to the sliding sleeve 52. The middle position of the surface of the slide 51 is fixedly connected to the gate opening machine 53. The output end of the gate opening machine 53 is connected to the threaded rod 54 through a thread. The surface of the threaded rod 54 is connected to the rotating component 55 through a thread. The surface of the rotating component 55 is fixedly connected to the meshing component 56.

[0045] When in use, the first motor 43 drives the screw rod 44 to rotate, and the inner side surface of the slide 51 is driven by the screw rod 44 to move upward. The slide 51 slides upward along the inner side surface of the side wall 42. A slide rod is fixedly connected along the inner side surface of the side wall 42. The inner side surface of the sliding sleeve 52 is slidably connected to the surface of the slide rod, making the sliding of the slide 51 more stable and reliable. A copper foil roll is placed inside the engaging component 56. The pushing component 46 pushes the engaging component 56 to the position of the opening and closing machine 53. The opening and closing machine 53 drives the threaded rod 54 to screw into the inner side surface of the rotating component 55, so that the rotating component 55 is tightly fixed to the slide 51. The engaging component 56 protects the copper foil roll, which solves the problem of how to prevent the copper foil roll from tilting and unwinding during transportation.

[0046] like Figure 6 、 Figure 7 、 Figure 8As shown, the rotating component 55 includes an internal threaded cylinder 551, the inner side surface of the internal threaded cylinder 551 is connected to the surface of the threaded rod 54 through a thread, and the internal threaded cylinder 551 is rotatably connected to the side of the threaded rod 54 away from the threaded rod 54 with a connecting cover 553, the surface of the connecting cover 553 is fixedly connected to the limiting pin 554, and there are several limiting pins 554. The surface of the internal threaded cylinder 551 is fixedly connected to the rotating disk 552, and the engaging component 56 includes an engaging cylinder 561, and a fixing hole 563 is provided on the surface of the engaging cylinder 561 near the end face, and the engaging cylinder 561 is connected to the surface of the limiting pin 554 through the fixing hole 563, and a gear surface 562 is provided on the surface of the engaging cylinder 561, which engages with the middle position of the inner side surface of the fixing component 41, and the inner side surface of the engaging cylinder 561 is fixedly connected to the elastic cylinder 564.

[0047] When in use, the elastic tube 564 is a cylindrical component made of rubber material. The inner side of the elastic tube 564 is wrapped with a copper foil tape. The limit pin 554 is pressed into the inside of the fixing hole 563, so that the connecting cover 553 and the engaging tube 561 can be quickly installed. The surface of the rotating disk 552 is embedded in the gap position between the sliding plates 414. The connecting cover 553 is pushed to the axial position of the gate opening machine 53, and the threaded rod 54 is screwed into the inner side of the internal threaded tube 551, so that the internal threaded tube 551 and the slide 51 are fixed. When the slide 51 moves obliquely upward, the connecting cover 553 and the internal threaded tube 551 are rotated to connect, so that the sliding friction of the engaging tube 561 is converted into rolling friction, which effectively reduces the energy consumption of the transportation device.

[0048] like Figure 4 、 Figure 8 As shown, the bottom of the limit platform 411 is fixedly connected to the top of the base 1, a rack surface 413 is provided in the middle position of the surface of the limit platform 411, the side position of the surface of the limit platform 411 is fixedly connected to the surface of the side wall 42, a slide groove 412 is provided on the surface of the limit platform 411 near the side wall 42, and a sliding plate 414 is fixedly connected to the lower position of the surface of the limit platform 411. A fixing hole 563 is provided on the surface of the engaging cylinder 561 near the end surface, and the engaging cylinder 561 is connected to the surface of the limit pin 554 through the fixing hole 563. A gear surface 562 is provided on the surface of the engaging cylinder 561, and the gear surface 562 is engaged with the middle position of the inner side surface of the fixing component 41. The inner side surface of the engaging cylinder 561 is fixedly connected to the elastic cylinder 564.

[0049] When in use, the meshing cylinder 561 protects the elastic cylinder 564 and the copper foil tape, the gear surface 562 meshes with the rack surface 413, and the surface of the meshing cylinder 561 is connected to the surface of the limit pin 554 through the fixing hole 563, so that the meshing cylinder 561 and the gate opening and closing machine 53 are rotatably connected, and the surface of the gate opening and closing machine 53 is slidably connected to the position of the limit platform 411 near the slide groove 412, so that the gate opening and closing machine 53 pushes the meshing cylinder 561 to roll upward, and the meshing between the tooth surfaces makes the meshing cylinder 561 more stable and less likely to shake when it moves obliquely upward, replacing the existing technology of using a friction belt to drive the copper foil tape to move. The weight of the copper foil tape is too large and it is easy to slide and collide on the surface of the friction belt. This transportation device effectively prevents the copper foil tape from being damaged and unrolled during transportation.
