[0031] The following paragraphs describe the present invention in more detail by way of example with reference to the accompanying drawings. The advantages and features of the present invention will become more apparent from the following description. It should be noted that the drawings are greatly simplified and not to exact scale, and are intended solely to facilitate and clearly illustrate the embodiments of the present invention.

[0032] The present invention provides an automatic sleeve cutting system. Figure 1 - Figure 2 , including a support platform 1 and a fixing unit, a clamping unit, a cutting unit 41 and a material receiving unit arranged in sequence in the horizontal direction; the fixing unit is arranged on the support platform 1, and includes a slit for allowing the sleeve to pass through; the clamping unit includes a translation device 31 and a clamping device 32, the clamping device 32 is used to clamp one end of the sleeve passing through the fixing unit, the translation device 31 drives the clamping device 32 to move, thereby driving the sleeve to move to the target cutting position located at the working position of the cutting unit 41; the material receiving unit includes a material receiving trough 51, which is arranged below the cutting unit 41 in the vertical direction for receiving the cut sleeve.

[0033] In this embodiment, the cutting system provided by the present invention includes the entire process of fixing, clamping, cutting, and collecting the sleeve. The fixing unit provides a slit that allows the sleeve to pass through, providing a fixing and guiding function for the sleeve. One end of the fixing unit is clamped by the clamping device 32 and moves with the movement of the translation device 31. During cutting, it is translated to a predetermined position, accurately positioning the target cutting position and the working position of the cutting unit 41. Through the cooperation of the translation device 31 and the clamping device 32, the sleeve can be quickly and accurately moved to the cutting position, and the cutting unit 41 can operate continuously, significantly improving production speed.

[0034] Furthermore, the fixing unit includes a pulley group 21 and a fixing hole 22, the pulley group 21 includes two pulleys arranged upper and lower, the rotation axes of the two pulleys are parallel, the slit is formed between the two pulleys, and the slit and the fixing hole 22 are connected in the horizontal direction.

[0035] Two pulleys, arranged parallel to their axes of rotation, provide a precise guide path for the sleeve, ensuring it does not deviate from its intended trajectory during movement, thus improving cutting accuracy. The slit formed by the pulley block 21 has a certain width to allow the sleeve to pass through and to limit its position. The use of the pulley block 21 ensures smooth transfer of the sleeve through the fixed unit, reducing friction and damage to the sleeve. Furthermore, the pulley block 21 can accommodate sleeves of varying diameters, enhancing the system's versatility.

[0036] For further information, please refer to Figure 3 - Figure 4 In the horizontal direction, the fixing hole 22 is arranged between the two pulley sets 21.

[0037] In this embodiment, the fixing hole 22 is located between the two pulley blocks 21, which helps to evenly distribute the sleeve on the two pulleys as it passes through, reducing the pressure on individual pulleys and extending the service life of the pulleys. The location of the fixing hole 22 allows the sleeve to be better fixed before cutting, reducing shaking during the cutting process, providing an additional support point for the sleeve, enhancing the sleeve's stability during transportation, and ensuring the sleeve's accurate position before entering the cutting unit 41, ensuring that the sleeve always remains on the correct path, and reducing cutting errors caused by sleeve position deviation.

[0038] Through the guidance and positioning of the fixed unit, the pause and adjustment time in the production process can be reduced, the production efficiency can be improved, the guiding process of the casing can be simplified, the operation complexity can be reduced, and it can also help reduce the accidental falling off or jamming of the casing during the transmission process, thereby improving the reliability of the system.

[0039] Furthermore, the lower end of the cutting unit 41 is connected to the first lifting unit 42 .

[0040] Furthermore, there is a predetermined height between the support platform 1 and the ground, and a receiving groove is provided on the support platform 1, and the receiving groove is used to receive the cutting unit 41 and the first lifting unit 42.

[0041] In this embodiment, the first lifting unit 42 drives the cutting unit 41 to move up and down to adjust the height, and also to achieve storage.

[0042] Furthermore, the clamping device 32 is detachably connected to the translation device 31 , and the accommodating groove is also used to accommodate the clamping device 32 .

[0043] In this embodiment, the clamping device 32 is removable, allowing for quick maintenance or replacement when necessary, reducing downtime. Different clamping devices 32 may be suitable for sleeves of different materials or sizes. The removable clamping device 32 allows the equipment to quickly adapt to different production needs. Furthermore, the receiving slot can accommodate the disassembled clamping device 32, allowing it to be properly stored when not in use, saving space and making the system more compact. Spare clamping devices 32 can also be configured for the entire system.

[0044] Furthermore, the material receiving unit further includes a material receiving plate 52 , and the material receiving plate 52 is arranged between the cutting unit 41 and the material receiving trough 51 in the vertical direction.

[0045] Furthermore, the receiving plate 52 includes a first plate and a second plate that are hinged to each other, the second plate is fixedly arranged on the supporting platform 1, and the first plate approaches or moves away from the second plate. When moving away from the second plate, the receiving plate 52 changes from a V-shape to a straight plate shape.

[0046] Furthermore, the back surface of the first plate away from the second plate is connected to a second lifting unit 53 .

[0047] In this embodiment, the receiving plate 52 forms a transition zone between the cutting unit 41 and the receiving trough 51, helping to guide the cut sleeves into the receiving trough 51 smoothly and reducing confusion and damage to the sleeves during the falling process. The second lifting unit 53 is connected to the back of the first plate and adjusts the angle between the first and second plates.

[0048] It can be understood that the first plate and the second plate are in a V shape, which can receive the sleeve that falls after cutting in front of the receiving trough 51. The V-shaped structure can buffer the falling speed of the sleeve after cutting and reduce the impact force. The second lifting unit 53 controls the first plate to move away from the second plate, and the angle between the first plate and the second plate gradually increases until the sleeve is allowed to slowly roll into the receiving trough 51. The sleeve rolls along the second plate into the receiving trough 51, realizing material collection and buffering. The cut sleeve rolls smoothly into the receiving trough 51, which simplifies the collection process, reduces the risk of operators directly contacting high-speed moving or falling sleeves, improves the safety of operation, and reduces damage or loss of sleeves due to improper collection by effectively receiving and guiding the sleeves, thereby reducing material waste.

[0049] In this embodiment, through this system, the sleeve is fixed in the pulley group 21, the fixing hole 22 and the pulley group 21 in sequence through the fixing unit, and the clamping device 32 clamps one end of the sleeve passing through the fixing unit. According to the required cutting length, the translation device 31 drives the clamping device 32 to move, thereby driving the sleeve to its target cutting position until it is located at the working position of the cutting unit 41. The cutting unit 41 cuts the sleeve at the working position, and the cut sleeve falls onto the receiving plate 52. At this time, the receiving plate 52 is V-shaped, and the second lifting unit 53 drives the first plate away from the second plate. The corner between the first plate and the second plate on the receiving plate 52 gradually increases, and the sleeve rolls along the first plate that is tilted away from the second plate to the receiving trough 51.

[0050] In summary, the automatic sleeve cutting system proposed in the present invention provides a structural basis for accurately cutting sleeves, ensuring the consistency of sleeve lengths, improving production efficiency, reducing scrap rates, and meeting the high quality requirements of modern automotive electronic systems for wiring harness components.

[0051] Obviously, those skilled in the art may make various modifications and variations to the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
