Description

Technical Field

[0001] This utility model relates to the field of slitting machine technology, and in particular to an automatic slitting machine for strip products. Background Technology

[0002] As is well known, FFC flexible connectors are a new type of data cable made by pressing PET insulating material and extremely thin tin-plated flat copper wire together using high-tech automated equipment. They have advantages such as flexibility, easy bending and folding, thinness, small size, simple connection, convenient disassembly, and easy solution of electromagnetic shielding (EMI), so they are used in a wide range of electronic products.

[0003] Currently, the production of FFC (Flexible Curd Cake) typically involves manufacturing the entire roll as a single piece, then slitting it into strips of a specific width according to the size of the applicable electronic product. During slitting, the roll will have corresponding cutting seams or lines, and the cutting blades must cut along these seams or lines, thus leading to the development of slitting machines. However, existing slitting machines generally have blades fixed in one position, specifically for slitting FFC of a certain width. When the cutting seams or lines of different FFC rolls change, the blades must be manually removed and reinstalled. When frequently slitting FFC strips of different widths, this repeated blade removal and installation significantly reduces slitting efficiency and hinders high-efficiency operation. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an automatic slitting machine for strip products.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An automatic slitting machine for strip products includes a main body and a feeding mechanism, a guiding mechanism, a slitting mechanism, and a receiving mechanism mounted on the main body. The feeding mechanism is connected to the guiding mechanism, and the receiving mechanism is located at the discharge port of the guiding mechanism. The slitting mechanism includes a gantry frame that spans above the guiding mechanism. A first linear module driven by a motor is mounted on the gantry frame. A mounting frame is fixedly mounted on the movable seat of the first linear module. A camera is mounted at the front end of the mounting frame. A second linear module driven by a motor is mounted vertically on the mounting frame. A blade holder is fixedly mounted on the movable seat of the second linear module. At least one vertically downward blade is mounted at the bottom of the blade holder, and the blade is located above the guiding mechanism. The main body also has a main control console for controlling the overall orderly operation.

[0007] Preferably, a first photoelectric sensor is provided on the gantry frame, a first trigger plate that works in conjunction with the first photoelectric sensor is provided on the movable seat of the first linear module, a second photoelectric sensor is provided on the mounting bracket, and a second trigger plate that works in conjunction with the second photoelectric sensor is provided on the movable seat of the second linear module.

[0008] Preferably, the feeding mechanism includes a material reel storing material, the material reel being rotatably mounted on the main body, and the material reel guiding the material to the feed inlet of the feeding mechanism via a first roller group.

[0009] Preferably, the material guiding mechanism includes a material guiding trough arranged horizontally on the main body, one end of the material guiding trough is used to receive the material introduced by the feeding mechanism, the other end of the material guiding trough is a discharge port, at least one driven roller shaft for receiving the material is provided in the material guiding trough, the gantry spans the material guiding trough, and the blade is located above the material guiding trough.

[0010] Preferably, a soft rubber cutting board is provided directly below the blade in the feed channel.

[0011] Preferably, the guide trough is provided with a vertical slide rail and a feed roller shaft at one end where the material is introduced. A slider is provided on the slide rail, and a self-rotating pressure roller shaft is provided on the slider. The material guided by the first roller shaft group first bypasses the pressure roller shaft and then enters the guide trough through the feed roller shaft.

[0012] Preferably, a supplementary light is provided on the side of the feed chute, and the light from the supplementary light is projected onto the detection area of ​​the camera.

[0013] Preferably, the receiving mechanism includes a first receiving reel and a second receiving reel mounted on the main body and rotatable by a motor. Both the first receiving reel and the second receiving reel receive materials from the guide chute via a second roller set.

[0014] By adopting the above solution, this utility model directly captures the material image with a camera to identify the location of the material cutting line. At the same time, it combines the first linear module and the second linear module to automatically move the blade to the cutting line. Depending on the different cutting lines of different materials, the distance moved by the first linear module will also be different, so the blade position can be automatically adjusted without repeatedly disassembling the blade, thus effectively improving work efficiency.

Thus, features defined with "first" and "second" may explicitly or implicitly include one or more of the stated features.

[0024] like Figures 1 to 6 As shown, this embodiment provides an automatic slitting machine for strip products, including a main body 1 and a feeding mechanism 2, a guiding mechanism 3, a slitting mechanism 4, and a receiving mechanism 5 mounted on the main body 1. The feeding mechanism 2 is connected to the guiding mechanism 3, and the receiving mechanism 5 is located at the discharge port of the guiding mechanism 3. The slitting mechanism 4 includes a gantry frame 41, which spans above the guiding mechanism 3. A first linear module 42 driven by a motor is provided on the gantry frame 41. A mounting frame 43 is fixedly installed on the movable seat of the first linear module 42. A camera 44 is provided at the front end of the mounting frame 43. A second linear module 45 driven by a motor is provided on the mounting frame 43 in a vertical direction. A blade holder 46 is fixedly installed on the movable seat of the second linear module 45. At least one vertically downward blade 47 is provided at the bottom of the blade holder 46, and the blade 47 is located above the guiding mechanism 3. The main body 1 is also provided with a main control console 6 for controlling the overall orderly operation.

[0025] In this embodiment, the camera 44 directly captures the image of the material to identify the location of the material cutting line. At the same time, the first linear module 42 and the second linear module 45 are combined to automatically move the blade 47 to the cutting line. The distance that the first linear module 42 moves will also be different depending on the cutting line of different materials, so the position of the blade 47 can be automatically adjusted without repeatedly disassembling the blade 47, thus effectively improving work efficiency.

[0026] In practice, the material is first threaded through the feeding mechanism 2, the guiding mechanism 3, and the receiving mechanism 5 in sequence. After threading, the camera 44 shoots downwards to capture the image. A corresponding cutting line, such as a black line, will appear on the surface of the material. Since the initial position (when the first straight module has not moved) is a fixed value, and the position captured by the camera 44 is always the same, with a fixed focal length, the distance that the first straight module 42 needs to move can be calculated from the captured image. The closer the black line is to the other side, the greater the distance needs to be moved. The specific distance to move is related to various parameters, such as the distance of the initial position and the proportional value calculated by the focal length of the camera 44. The proportional value is then converted into the actual movement value of the first straight module 42. This method of detection using the camera 44 is a current technology, most commonly used in 3D printing. Therefore, this embodiment will not elaborate on the specific conversion process. Once the required distance is determined, the first linear module 42 moves gradually under the drive of a motor. When the blade 47 is positioned directly above the cutting line, the first linear module 42 stops moving. Subsequently, the second linear module 45, driven by another motor, moves downwards until the blade 47 passes through the material with the cutting edge facing the material's infeed direction. As the material moves, slitting can then be performed. When changing materials, the first linear module 4 and the second linear module 45 reset the blades and, relying on the camera 44 for recognition, move the blade 47 to the appropriate position.

[0027] Furthermore, to ensure that the first linear module 42 and the second linear module 45 are reset to the accurate position, a first photoelectric sensor 401 is provided on the gantry 41 in this embodiment, a first trigger piece 402 that works in conjunction with the first photoelectric sensor 401 is provided on the movable seat of the first linear module 42, a second photoelectric sensor 403 is provided on the mounting bracket 43, and a second trigger piece 404 that works in conjunction with the second photoelectric sensor 403 is provided on the movable seat of the second linear module 45. This effectively ensures that after reset, they are all in the same position, so that the camera 44 is always in the same position when taking pictures, without any errors.

[0028] Furthermore, regarding the specific structure of the feeding mechanism 2 in this embodiment, it mainly includes a material reel 21 storing materials. The material reel 21 is rotatably mounted on the main body 1. The material reel 21 guides the materials to the inlet of the guiding mechanism 3 through the first roller group 22. The guiding mechanism 3 includes a guiding groove 31 arranged horizontally on the main body. One end of the guiding groove 31 is used to receive the materials introduced by the feeding mechanism 2, and the other end of the guiding groove 31 is the outlet. At least one driven roller 32 for receiving materials is provided in the guiding groove 31. The gantry frame 41 spans the guiding groove 31, and the blade 47 is located above the guiding groove 31. To protect the blade 47, a soft rubber cutting board 33 is provided directly below the blade 47 in the guiding groove 31 in this embodiment.

[0029] Furthermore, to better tighten the material, the guide trough 31 in this embodiment is equipped with a vertical slide rail 34 and a feed roller shaft 35 at the material inlet end. A slider 36 is mounted on the slide rail 34, and a self-rotating pressure roller shaft 37 is mounted on the slider 36. The material guided by the first roller shaft group 22 first passes around the pressure roller shaft 37 and then enters the guide trough 31 through the feed roller shaft 35. In this way, the material being guided in the guide trough 31 can be automatically tightened by the gravity of the pressure roller shaft 37. The slider 36 can move freely up and down, so that tightening can be achieved while avoiding rigid tightening.

[0030] Furthermore, in order to make the camera 44 capture clearer images, a supplementary light 38 is provided on the side of the material guide trough 31 in this embodiment. The light from the supplementary light 38 is projected onto the detection area of ​​the camera 44, thus avoiding the inability to identify materials in dim light.

[0031] Furthermore, regarding the receiving mechanism 5, the receiving mechanism 5 in this embodiment includes a first receiving reel 51 and a second receiving reel 52 mounted on the main body 1 and rotatable by a motor. Both the first receiving reel 51 and the second receiving reel 52 receive materials from the guide trough 31 through the second roller group 53. The first receiving reel 51 and the second receiving reel 52 can each receive the separated materials.

[0032] Furthermore, it should be noted that the material reel 21, the first take-up reel 51, and the second take-up reel 52 are all commercially available reels that meet the requirements for disassembly and assembly. Meanwhile, to ensure the power for material transport, at least one roller in the first roller group 22 is equipped with a rotary motor, enabling the roller to rotate.

[0033] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural or procedural 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.
