A copper strip cutting apparatus

Abstract

This utility model discloses a copper strip cutting device, including a feeding turntable, a material transfer assembly, a signal transmission contact, and a cutting assembly. The signal transmission contact is electrically connected to a control board, which controls the rotation of the feeding turntable. The material transfer assembly drives the copper strip to move, and during the movement of the copper strip, it comes into contact with the signal transmission contact. At this time, the signal transmission contact sends an electrical signal to the control board to control the rotation of the feeding turntable and output the copper strip, thus disconnecting the copper strip from the signal contact. The signal contact includes a bracket and a conductive foil hanging on it. The copper strip rises from below the conductive foil and comes into contact with it. This solution uses a conductive foil, whose flexibility acts as a buffer within its height range. Within this height range, the copper strip and the conductive foil can conduct electrical signals, effectively reducing the problem of equipment or material damage caused by poor contact.

Description

Technical Field

[0001] This utility model belongs to the technical field of metal processing equipment, and in particular relates to a copper strip cutting device. Background Technology

[0002] Copper strip is cut to the required length using a copper strip cutting machine. The machine typically includes a feeding turntable and a cutting blade. The copper strip is fed onto the turntable and cut by the blade. To reduce energy waste, a contact rod for transmitting electrical signals is usually included, connected to a controller. The copper strip is placed below and falls under its own weight. During cutting, the copper strip is stretched upwards, bringing it into contact with the contact rod. The contact rod then transmits a signal to the controller, causing the feeding turntable to rotate, allowing a portion of the strip to slide off the turntable under its own weight.

[0003] In daily use, the applicant found that the contact rod would experience problems such as poor contact due to corrosion after prolonged use. When the copper strip at the front end was still being transported, the copper strip would make strong contact with the contact rod with a force far exceeding the normal contact force, which would cause scratches on the copper strip.

[0004] Based on the above problems, the applicant designed a device that allows copper strips to have a larger contact area or contact time on contacts that transmit electrical signals, effectively reducing the risk of copper strip scratches. Utility Model Content

[0005] The purpose of this invention is to provide a copper strip cutting device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a copper strip cutting device, comprising a feeding turntable, a material transfer assembly, a signal transmission contact, and a cutting assembly, wherein the signal transmission contact is electrically connected to a control board, and the control board is capable of controlling the feeding turntable to rotate a set number of times. The material transfer assembly is used to drive the copper strip to move. During the movement of the copper strip, the copper strip will come into contact with the signal transmission contact. At this time, the signal transmission contact will send an electrical signal to the control board to control the feeding turntable to rotate and output the copper strip, thereby causing the copper strip to disconnect from the signal contact. The signal contact includes a bracket and a conductive foil hanging thereon, and the copper strip rises from below the conductive foil and contacts the conductive foil.

[0007] Preferably, the feeding turntable is horizontally mounted on a chassis, and a motor for driving the feeding turntable to rotate is provided inside the chassis. A guide rod is provided on the chassis, and the copper strip hangs down after being attached to the guide rod.

[0008] Preferably, the material transfer assembly includes a worktable and a material transfer roller disposed on the worktable. The material transfer roller includes a drive roller and a pressure roller. A second motor for controlling the rotation of the drive roller is disposed on the worktable. An opening and closing assembly for controlling the pressure roller to move away from or closer to the drive roller is also disposed on the worktable.

[0009] Preferably, the opening and closing assembly includes two upright plates set on the workbench, each of which is hinged with a rotating plate. The pressure roller is rotatably connected to the two rotating plates, and the movement of the drive roller and the pressure roller is achieved by controlling the rotation of the rotating plates in the vertical direction.

[0010] Preferably, the rotating plate is provided with a distance adjustment component, which can adjust the distance between the drive roller and the pressure roller.

[0011] Preferably, the workbench is further provided with a material guiding component, which includes a guide frame. The guide frame has several adjustment slots arranged in an array, and several adjustment bolts slide in the adjustment slots. The adjustment bolts are clamped and fixed to the guide frame by nuts.

[0012] Preferably, the workbench is further provided with a leveling assembly, which includes horizontally arranged upper and lower leveling rollers. A copper strip passes through the gap between the upper and lower leveling rollers. The upper leveling roller presses on the copper strip, and the copper strip overlaps the lower leveling roller. Each upper leveling roller is positioned above two adjacent lower leveling rollers. A guide seat is provided on the workbench, and the lower leveling roller is rotatably connected to the guide seat. A connecting frame slides on the guide seat, and several upper leveling rollers are rotatably connected to the connecting frame. The upper leveling rollers move closer to or further away from the lower leveling rollers by sliding the connecting frame on the guide seat.

[0013] Preferably, the cutting assembly includes a cutting frame, on which a cutting drive cylinder is provided, and a cutting blade is provided at the drive end of the cutting drive cylinder.

[0014] Preferably, a scratch-resistant mat is laid on the ground, and the copper strip output by the feeding turntable overlaps on the scratch-resistant mat.

[0015] The beneficial effects of this utility model are as follows: By setting a conductive foil, the flexibility of the conductive foil itself acts as a buffer within the height range of the conductive foil. Within this height range, the copper strip and the conductive foil can conduct electrical signals. This expands the contact time and contact area of ​​the copper strip, greatly enhancing the possibility of electrical signals being generated through contact, and effectively reducing the problem of equipment or material damage caused by poor contact. The copper strip is facilitated by the opening and closing mechanism. By incorporating a distance adjustment mechanism, this device can be adapted to use copper strips of varying thicknesses. One solution to the problem is that the coiled copper strip may be uneven. The straightening component can effectively solve this problem. Attached Figure Description

Detailed Implementation

[0017] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0018] Example: See Figure 1A copper strip cutting device includes a feeding assembly 1, a transferring assembly 2, a signal transmission contact, and a cutting assembly 3. The signal transmission contact is electrically connected to a control board. The feeding assembly 1 includes a housing 102 and a horizontally arranged feeding turntable 103 rotatably connected to the housing 102. A motor for driving the feeding turntable 103 to rotate is provided inside the housing 102. The control board can control the feeding turntable 103 to rotate according to a set number of revolutions. Specifically, it can be expressed as 0.5 revolutions for the first 10 revolutions, 1 revolution for revolutions 11-20, or a fixed number of revolutions each time, or other setting methods. The material transfer component 2 is used to drive the copper strip 11 to move. During the movement of the copper strip 11, the copper strip 11 will come into contact with the signal transmission contact. At this time, the signal transmission contact will send an electrical signal to the control board to control the feeding turntable 103 to rotate and output the copper strip 11, thereby causing the copper strip 11 to disconnect from the signal contact. The signal contact includes a bracket 8 (the horizontal part of which corresponds to the contact rod in the background art) and a conductive foil 9 hanging on it. The copper strip 11 rises from below the conductive foil 9 and contacts the conductive foil 9. The conductive foil 9 is preferably set at more than 20 cm. Among them, an anti-scratch pad 10 is laid on the ground, and the copper strip 11 output by the feeding turntable 103 overlaps on the anti-scratch pad 10. The anti-scratch pad 10 can be a cardboard shell.

[0019] Among them, see Figure 1 , Figure 2 The housing 102 is provided with a guide rod 101. The copper strip 11 hangs down after overlapping the guide rod 101. Specifically, the guide rod 101 includes an overlapping rod 1011 and a stop rod 1012 fixedly installed on the housing 102. The overlapping rod 1011 is L-shaped, with one end horizontally fixed to the housing 102 and the other end inclined to the horizontal plane so that the copper strip 11 can overlap it. A stop rod is fixed on the inclined section so that one side of the copper strip 11 can abut against it, thereby realizing that the copper strip 11 hangs down after overlapping the guide rod 101.

[0020] Among them, see Figure 3 The material transfer assembly 2 includes a worktable 7 and a material transfer roller disposed on the worktable 7. The material transfer roller includes a drive roller 201 and a pressure roller 202. The worktable 7 is provided with a motor 203 for controlling the rotation of the drive roller 201. The worktable 7 is also provided with an opening and closing assembly 4 for controlling the pressure roller 202 to move away from or closer to the drive roller 201.

[0021] See Figure 3The opening and closing assembly 4 includes a base 401 and two upright plates 402 erected on the base 401. The base 401 is set on the workbench 7. The drive roller 201 is rotatably connected to the base 401. Each of the upright plates 402 is hinged with a rotating plate 403. The pressure roller 202 is rotatably connected to the two rotating plates 403. By controlling the rotation of the rotating plates 403 in the vertical direction, the drive roller 201 and the pressure roller 202 can be brought closer and further apart.

[0022] The rotating plate 403 is provided with a distance adjustment component 404, which can adjust the distance between the drive roller 201 and the pressure roller 202. The distance adjustment component 404 can be a bolt threaded onto the rotating plate 403, which passes through the rotating plate 403 and can abut against the worktable 7 (in this embodiment, there is a guide frame 61 on the worktable 7, and the distance adjustment component 404 abuts against the top surface of the guide frame 61).

[0023] Among them, see Figure 4 The workbench 7 is also provided with a material guiding component 6. The material guiding component 6 includes a guide frame 61. Several elongated adjustment grooves 611 are arrayed on the guide frame 61. Several adjustment bolts 62 slide in the adjustment grooves 611. The adjustment bolts 62 are clamped and fixed on the guide frame 61 by nuts.

[0024] Among them, see Figure 5 The workbench 7 is also equipped with a leveling assembly 5, which includes horizontally arranged upper leveling rollers 52 and lower leveling rollers 51. A copper strip 11 passes through the gap between the upper leveling rollers 52 and the lower leveling rollers 51. The upper leveling rollers 52 press on the copper strips 11, and the copper strips 11 overlap the lower leveling rollers 51. Each upper leveling roller 52 is positioned above two adjacent lower leveling rollers 51. The workbench 7 is provided with a guide seat 53. The smoothing lower roller 51 is rotatably connected to the guide seat 53. A connecting frame 54 slides on the guide seat 53. Several smoothing upper rollers 52 are rotatably connected to the connecting frame 54. The smoothing upper rollers 52 move closer to or away from the smoothing lower roller 51 by sliding the connecting frame 54 on the guide seat 53. In this embodiment, the guide seat 53 is a frame with a guide hole on its top surface facing downward. A guide post 55 is fixed on the connecting frame 54, passing through the guide hole, so that it can move up and down in a directional manner. A threaded hole is also opened downward on the top surface of the guide seat 53. A limiting bolt 56 is threaded into the threaded hole. The lower end of the limiting bolt 56 abuts against the connecting frame 54 to prevent the smoothing upper rollers 52 from rising under force.

[0025] Among them, see Figure 6The cutting assembly 3 includes a cutting frame 31, on which a cutting drive cylinder 32 is provided. A knife holder 33 is fixed at the output end of the cutting drive cylinder 32, and the cutting knife 34 is mounted on the knife holder 33.

[0026] The workbench 7 is equipped with a control system 12 that can set working parameters (cutting length, motor 203 running speed, etc.).

[0027] Working principle and process: When using the equipment of this solution, the parameters are set by the control system 12, one end of the copper strip 11 installed on the feeding turntable 103 is pulled out and passed through the guide rod 101 from under the conductive foil 9, then through the smoothing component 5, then through the guide component 6 through the transfer component 2, and then to the cutting component 3. When the equipment is started, the transfer component 2 drives the copper strip 11 to move towards the cutting component 3. After the copper strip 11 reaches the required length, it stops transporting the copper strip 11. The cutting component 3 then cuts the copper strip 11. During this process, if the copper strip 11 comes into contact with the conductive foil 9, the conductive foil 9 will send a signal to the controller. The controller will then control the motor to rotate, thereby enabling the copper strip 11 to be transported.

[0028] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural transformations made based on the description and drawings of this utility model, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
