Description

Technical Field

[0001] The present application relates to the technical field of wire harness copper foil processing equipment, and in particular to an automatic copper foil cutting device. Background Art

[0002] Currently, when crimping terminals on cable harnesses, it is necessary to first strip the internal wire cores to expose them before crimping the terminals. During the stripping process, the copper foil at the end of the harness will be damaged, so after crimping the terminals, it is necessary to wrap the copper foil around the crimping part.

[0003] The traditional operation is to wrap the copper foil around the wire for one and a half circles, then tear it off manually and continue to the next one, repeating the same action. The disadvantage of manual operation is that the length of the copper foil cannot be controlled and the ends are uneven. Utility Model Content

[0004] In order to solve the above technical problems, the present application provides an automatic copper foil cutting device, which has the advantages of ensuring the cutting length and uniformity of the aluminum foil.

[0005] In order to achieve the above object, the technical solution of the utility model is as follows:

[0006] An automatic copper foil cutting device comprises a bracket, a material unwinding assembly, a cutting assembly, a material receiving assembly and a winding assembly for winding release paper which are sequentially arranged along the conveying direction of the material belt;

[0007] The cutting assembly includes a cutting frame and a release plate, the release plate is provided with a material trough for the aluminum foil strip to pass through, a tensioning roller is provided below the release plate, the cutting frame is provided with a moving driving member for driving the release plate to move, and a cutting member for cutting the copper foil is provided between the material trough and the material receiving assembly.

[0008] The above technical solution is implemented so that after the copper foil strip passes through the material trough, the release paper of the copper foil strip is attached to the end of the material trough and then folded into the tensioning roller. At this time, because the copper foil is not subjected to external force, the copper foil will not bend along with the release paper. Therefore, after being detached from the release paper, it is transported forward horizontally and then cut by the cutting piece, thereby achieving the effect of automatic cutting. The extending length of the copper foil can be controlled by the distance that the release plate is moved by the moving driving piece, thereby ensuring the cutting length and uniformity of the aluminum foil.

[0009] As a preferred solution of the present application, the mobile driving component includes a carrier, a transverse slide rail arranged on the carrier, and a bearing plate arranged on the transverse slide rail. The carrier is provided with a transverse driving cylinder for moving the bearing plate along the transverse slide rail.

[0010] To implement the above technical solution, the carrier plate is driven to move toward the receiving piece by a transverse driving cylinder, at which time the winding assembly stops moving, and the release plate moves toward the receiving assembly, so that the end drives the release paper forward, thereby pulling the copper foil strip to gradually release the material. Because the copper foil strip is pulled, the release paper will be precisely attached to the end of the release plate, thereby ensuring that the copper foil and the release paper can be separated normally.

[0011] As a preferred solution of the present application, the cutting member includes a cutting knife below the release plate, and a cutting drive member for driving the cutting knife to move up and down.

[0012] The above technical solution is realized by moving the cutting driving member upward so that the cutting knife attached to the release plate moves upward, thereby cutting off the protruding copper foil.

[0013] As a preferred solution of the present application, the cutting assembly further comprises a vertical cylinder, the carrier is arranged on a telescopic rod of the vertical cylinder, and the bracket is provided with an abutment plate for abutting the top end of the release plate.

[0014] By implementing the above technical solution, the upper end of the vertical release plate abuts against the abutting plate under the action of the vertical cylinder, so that the copper foil on one side of the cutting knife is pressed tightly.

[0015] As a preferred solution of the present application, a cover plate is fixed above the material trough, a clamping cylinder is arranged below the release plate, a pressure plate is arranged on the telescopic rod on the clamping cylinder, and the clamping cylinder drives the pressure plate to press against the cover plate.

[0016] By implementing the above technical solution, the copper foil strip can be pressed against the cover plate by the pressing plate and move back and forth with the release plate without relative movement, thereby ensuring the accuracy of the copper foil cutting length.

[0017] As a preferred solution of the present application, the material receiving assembly includes a material receiving tray and a motor for driving the material receiving tray to rotate.

[0018] By implementing the above technical solution, the copper foil is cut by the cutting knife and placed on the receiving tray, and then the receiving motor drives the copper foil on the receiving tray to rotate and leave the cutting position, so that a person can pick it up.

[0019] As a preferred solution of the present application, a downward pressure cylinder is arranged above the receiving tray, and a rubber pressure cap is arranged on the telescopic rod of the downward pressure cylinder.

[0020] By implementing the above technical solution, the copper foils on both sides of the cutting knife are pressed tightly, thereby ensuring that the copper foils are cut normally.

[0021] As a preferred solution of the present application, the discharge assembly includes a discharge tray rotatably disposed on a bracket, and a plurality of transition discharge rollers are disposed between the discharge tray and the release plate.

[0022] As a preferred solution of the present application, the winding assembly includes a receiving tray rotatably arranged on a bracket, and a receiving motor for driving the receiving tray to rotate, and a plurality of receiving transition rollers are arranged between the receiving tray and the tensioning roller.

[0023] To implement the above technical solution, when the copper foil is cut off, the release plate retreats, thereby loosening the release paper. At this time, the receiving motor drives the receiving tray to rotate, thereby tightening the release paper.

[0024] In summary, the present application includes at least one of the following beneficial technical effects:

[0025] 1. After the copper foil strip passes through the material trough, the release paper of the copper foil strip is attached to the end of the material trough and then folded into the tensioning roller. At this time, because the copper foil is not subjected to external force, the copper foil will not bend along with the release paper. Therefore, after being separated from the release paper, the copper foil is transported forward horizontally and then cut by the cutting piece, thereby achieving the effect of automatic cutting. The extension length of the copper foil can be controlled by the distance that the release plate is moved by the moving drive part, thereby ensuring the cutting length and neatness of the aluminum foil;

[0026] 2. The copper foil strip can be pressed against the cover plate by the pressing plate and move back and forth with the release plate without relative movement, thus ensuring the accuracy of the copper foil cutting length. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] The present application embodiment discloses a copper foil automatic cutting device. Figure 1 A copper foil automatic cutting device comprises a bracket 1, a material unwinding component 2, a cutting component 3, a material receiving component 4 and a winding component 5 for winding release paper which are sequentially arranged along the conveying direction of the material belt.

[0034] The unloading assembly 2 includes an unloading tray 21 rotatably arranged on the bracket 1, and a plurality of transition unloading rollers 22 are arranged between the unloading tray 21 and the release plate 32. That is, the copper foil roll can be placed on the unloading tray 21, and then the copper foil strip is pulled by the winding assembly 5 so that it passes through a plurality of filtering unloading rollers and is sent to the cutting assembly 3.

[0035] The cutting assembly 3 includes a cutting frame 31 and a release plate 32. The release plate 32 is provided with a material slot 321 for the copper foil strip to pass through. A tensioning roller 33 is provided below the release plate 32, so that after the copper foil strip passes through the material slot 321, the release paper of the copper foil strip is attached to the end of the material slot 321 and then folded into the tensioning roller 33. At this time, because the copper foil is not subjected to external force, the copper foil will not bend with the release paper, so that it will be separated from the release paper and transported forward horizontally. The cutting frame 31 is provided with a moving driving member 34 for driving the release plate 32 to move, and a cutting member 35 for cutting the copper foil is provided between the material slot 321 and the material receiving assembly 4.

[0036] The movable driving member 34 includes a carrier 341, a transverse slide rail 342 arranged on the carrier 341, a bearing plate 343 slidably arranged on the transverse slide rail 342, and a release plate 32 arranged on the bearing plate 343. A transverse driving cylinder 344 is arranged on the carrier 341 for moving the bearing plate 343 along the transverse slide rail 342, that is, the bearing plate 343 is driven to move toward the receiving member by the transverse driving cylinder 344, at which time the winding assembly stops moving, and at this time the release plate 32 moves toward the receiving assembly 4, so that the end drives the release paper forward, thereby pulling the copper foil strip to gradually discharge the material, and because the copper foil strip is pulled, the release paper will be precisely attached to the end of the release plate 32, thereby ensuring that the copper foil and the release paper can be separated normally.

[0037] The cutting member 35 includes a cutting knife 351 below the release plate 32, and a cutting drive member 352 for driving the cutting knife 351 to move up and down. The cutting drive member 352 is a cylinder, that is, the cutting knife 351 moves up by the cutting drive member 352, thereby cutting the protruding copper foil. When the cutting knife 351 moves up, the copper foil may bend upward, resulting in the copper foil being unable to be cut normally. The cutting assembly 3 also includes a vertical cylinder 37. The carrier 341 is set on the telescopic rod of the vertical cylinder 37. The bracket 1 is provided with an abutment plate 36 for the top end of the release plate 32 to abut. Then, under the action of the vertical cylinder 37, the upper end of the release plate 32 abuts against the abutment plate 36, so that the copper foil on one side of the cutting knife 351 is pressed tightly. A downward pressure cylinder 381 is provided above the material receiving assembly 4, and a rubber pressure cap 382 is provided on the telescopic rod of the downward pressure cylinder 381, so that the end of the copper foil away from the release plate 32 is pressed against the material receiving assembly 4 by the rubber pressure cap 382, ​​so that the copper foil on both sides of the cutting knife 351 is pressed, thereby ensuring that the copper foil is cut normally. At the same time, the length of the copper foil can be controlled by controlling the distance that the lateral driving cylinder 344 drives the release plate 32 to move, so that the cutting length of the copper foil can be controlled.

[0038] The receiving assembly 4 includes a receiving tray 41 and a receiving motor 42 for driving the receiving tray to rotate. That is, after the copper foil is cut by the cutting knife 351, it is placed on the receiving tray 41, and then the receiving motor 42 drives the copper foil on the receiving tray 41 to rotate and leave the cutting position, so that a person can pick it up.

[0039] The winding assembly includes a receiving tray 51 rotatably arranged on the bracket 1, and a receiving motor 52 for driving the receiving tray 51 to rotate. A plurality of receiving transition rollers 53 are arranged between the receiving tray 51 and the tensioning roller 33. That is, when the copper foil is cut off, the release plate 32 retreats, thereby loosening the release paper. At this time, the receiving motor 52 drives the receiving tray 51 to rotate, thereby tightening the release paper.

[0040] When the release plate 32 retracts, in order to prevent the copper foil strip from retracting together and causing the subsequent copper foil extension length to change, a clamping cylinder 391 is arranged under the plate, and a pressing plate 392 is arranged on the telescopic rod on the clamping cylinder 391. The clamping cylinder 391 drives the pressing plate 392 to press against the cover plate 393. The cover plate 393 is fixed above the material trough, so that the copper foil strip can be pressed on the cover plate 393 by the pressing plate 392, and move back and forth with the release plate 32 without relative movement, thereby ensuring the accuracy of the copper foil cutting length.

[0041] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
