Technical Field

[0001] The present invention relates to the technical field of cable processing, and particularly to a cable length measurement and cutting system and method. Background Art

[0002] During the process of cable laying, engineering teams often encounter situations where equal-length cables are required. This usually occurs in symmetrical layouts, specific design requirements, or to ensure the consistency and stability of power transmission or data communication. To meet these specific needs, precise cutting of cables is particularly important.

[0030] First embodiment

[0031] Please refer to Figures 1 to 6, the present invention provides a cable length measurement and cutting system, including a base 101 and a support frame 102. The support frame 102 is fixedly connected to the base 101 and is located on one side of the base 101. It further includes a cutting assembly 103, a length detection assembly 104, and a driving assembly 105. The driving assembly 105 includes a support plate 106, a driving roller 107, an adjustment plate 108, and a driven roller 109. The support plate 106 is fixed on the support frame 102. The driving roller 107 is rotatably arranged on the support plate 106. The adjustment plate 108 is slidably arranged on one side of the support plate 106. The driven roller 109 is arranged on one side of the adjustment plate 108. The cutting assembly 103 includes a cutting blade 110, a cutting cylinder 111, and a mounting block 112. The mounting block 112 is slidably arranged on the support frame 102. The output end of the cutting cylinder 111 is connected to the mounting block 112. The cutting blade 110 is arranged on the mounting block 112. The length detection assembly 104 is arranged on one side of the mounting block 112 and is used to detect the length of the cable.

[0032] In this embodiment, the support plate 106 of the driving assembly 105 is firmly installed on the support frame 102, providing a stable support foundation for other components. The driving roller 107 is rotatably arranged on the support plate 106 and can rotate flexibly as needed to push the cable forward. The adjustment plate 108 is slidably arranged on one side of the support plate 106, enabling the user to make fine adjustments according to the specific size of the cable to adapt to the processing requirements of different cable specifications. The driven roller 109 is arranged on one side of the adjustment plate 108 and works in cooperation with the driving roller 107 to ensure the cable passes smoothly.

[0033] The cutting assembly 103 consists of a cutting blade 110, a cutting cylinder 111, and a mounting block 112. The mounting block 112 can slide on the support frame 102 to facilitate adjusting the cutting position. The output end of the cutting cylinder 111 is connected to the mounting block 112. When the cable needs to be cut, the cylinder pushes the mounting block 112, and then drives the cutting blade 110 to complete the cutting action.

[0034] The length detection assembly 104 is arranged on one side of the mounting block 112 and is used to monitor and record the length of the cable in real time. This not only improves the accuracy of the work but also greatly simplifies the operation process, enabling easy handling even in situations where strict requirements for cable length are imposed. In short, this cable length measurement and cutting system, through its unique design and precise structure, realizes the automation and intelligence of cable length measurement and cutting, greatly improving the work efficiency and accuracy.

[0035] The cutting assembly 103 further includes a return spring 113, and the return spring 113 is arranged between the mounting block 112 and the cutting cylinder 111.

[0036] After the cable cutting operation is completed, the return spring 113 can automatically apply a reverse force to prompt the mounting block 112 and the cutting blade 110 to quickly and smoothly return to the initial position. This automatic reset mechanism not only improves work efficiency and reduces the need for manual intervention, but also ensures the consistency and accuracy of each cutting action.

[0037] The cutting assembly 103 further includes a stretching sleeve 114, which is arranged on one side of the mounting block 112 and is used to straighten the cable to be cut.

[0038] The stretching sleeve 114 includes a friction block 115, a connecting rod 116, a second spring 117, a sliding rod 118, a pressing block 119 and a bottom plate 120. The bottom plate 120 is slidably arranged on the support frame 102, the pressing block 119 is slidably arranged on the bottom plate 120, the friction block 115 is arranged on one side of the mounting block 112, the connecting rod 116 is rotatably connected to the friction block 115, the sliding rod 118 is slidably connected to the connecting rod 116 and is rotatably connected to the pressing block 119, and the second spring 117 is arranged between the connecting rod 116 and the sliding rod 118.

[0039] During use, when cutting the cable, the friction block 115 moves downward together with the mounting block 112 to drive the connecting rod 116 to push the pressing block 119 downward to cooperate with the bottom plate 120 to clamp the cable. Then, further pushing the connecting rod 116 can drive the pressing block 119 and the bottom plate 120 to slide to straighten the cable. By the support of the second spring 117 on the sliding rod 118, a relatively constant pressure is provided to straighten the cable. When the mounting block 112 continues to move downward, the friction block 115 moves to the limit position, so that the mounting block 112 can overcome the friction force with the friction block 115 and continue to move downward to drive the cutting blade 110 to cut the straightened cable, thereby making the cutting position more accurate.

[0040] The stretching sleeve 114 further includes a friction pad 121, which is arranged below the pressing block 119.

[0041] The design of the friction pad 121 is aimed at increasing the friction force on the surface of the cable to ensure that the cable can remain stable and immovable during the straightening process. By using a special material with a high friction coefficient to make the friction pad 121, it can effectively prevent the cable from sliding or rotating under the pressure of the pressing block 119, thus ensuring the accuracy and smoothness of the stretching operation.

[0042] The adjusting plate 108 includes an adjusting plate body 122, a locking rod 123, a locking piece 124, and a pressing spring 125. The adjusting plate body 122 is slidably disposed on the support frame 102. The pressing spring 125 is disposed between the adjusting plate body 122 and the support plate 106. The locking rod 123 is threadedly connected to the adjusting plate body 122 and is located on one side of the adjusting plate body 122. The locking piece 124 is rotatably disposed on one side of the locking rod 123 and is close to the support plate 106.

[0043] The adjusting plate body 122 is slidably disposed on the support frame 102. This design allows the adjusting plate 108 to be flexibly adjusted according to the specific size of the cable. In this way, the operator can easily adjust the position of the driven roller 109 for cables of different diameters, thereby achieving the best working state.

[0044] To ensure that the adjusting plate 108 remains stable after being adjusted to the appropriate position, a combined mechanism of the locking rod 123 and the locking piece 124 is introduced in the design. The locking rod 123 is fixed to the adjusting plate body 122 by threaded connection and is located on one side of the adjusting plate body 122. This design enables the operator to precisely control the position locking of the adjusting plate 108 by rotating the locking rod 123. The locking piece 124 is rotatably disposed on one side of the locking rod 123 and is close to the support plate 106. When it is necessary to lock the position of the adjusting plate 108, the locking piece 124 will closely fit the support plate 106 under the action of the locking rod 123, forming a firm locking point to prevent the adjusting plate 108 from being displaced due to external forces.

[0045] In addition, the pressing spring 125 is cleverly disposed between the adjusting plate body 122 and the support plate 106. The main function of the pressing spring 125 is to provide a continuous pressure for the adjusting plate 108, enabling it to closely fit the support plate 106. At the same time, it can also absorb the vibrations generated during the working process to a certain extent, reducing the adverse effects on the system stability. The presence of the pressing spring 125 helps to increase the contact pressure between the driven roller 109 and the driving roller 107, ensuring that the cable can be smoothly transmitted between the two rollers and avoiding the occurrence of slipping.

[0046] The driving assembly 105 further includes a conical guide sleeve 126. The conical guide sleeve 126 is disposed on one side of the adjusting plate 108 and is used to guide the moving direction of the cable.

[0047] The design of the conical guide sleeve 126 fully considers the angle change requirements when the cable enters and exits the drive assembly 105. Its conical structure can effectively guide the cable to smoothly transition between the drive roller 107 and the driven roller 109, reducing the risk of increased friction or cable position deviation caused by sudden angle changes. This design is particularly suitable for handling cables of different diameters because the shape of the conical guide sleeve 126 allows the cable to enter the drive system at the optimal angle, enabling smooth transmission regardless of its size.

[0048] The drive assembly 105 further includes a triangular abutment block 127, a control cylinder 128, and a third spring 129. The triangular abutment block 127 is slidably disposed on one side of the drive roller 107 and the driven roller 109. The output end of the control cylinder 128 is connected to the triangular abutment block 127, and the third spring 129 is disposed between the triangular abutment block 127 and the control cylinder 128.

[0049] In order to keep the rear cable stable during cutting, the present application is provided with a triangular abutment block 127, which can drive the triangular abutment block 127 to move through the control cylinder 128 to limit the drive roller 107, so that the drive roller 107 remains stationary during cutting and at the same time prevents the rear cable from sliding. After cutting is completed, the triangular abutment block 127 can be driven to reset by the third spring 129.

[0050] The length detection assembly 104 includes a photoelectric sensor 130, a rotation angle detection sensor 131, a length compensation unit 132, and a control unit 133. The photoelectric sensor 130 is disposed on one side of the mounting block 112 and is used to start length detection when the cable passes through the photoelectric sensor 130. The rotation angle detection sensor 131 is disposed on one side of the drive roller 107 and is used to detect the rotation angle data of the drive roller 107 when length detection is started. The length compensation unit 132 is used to calculate the cable length based on the rotation angle data and compensate for the systematic error of the calculated cable length. The control unit 133 is used to start the cutting cylinder 111 to cut the cable after the cable length reaches a preset value.

[0051] The photoelectric sensor 130 is disposed on one side of the mounting block 112. When the cable passes through the photoelectric sensor 130, it immediately detects the presence of the cable and starts the length detection process. This design not only improves the automation level of the system but also ensures that the passage of each cable can be accurately recorded, providing a trigger point for subsequent length calculation.

[0052] The corner detection sensor 131 is located on one side of the driving roller 107. Once the photoelectric sensor 130 detects the cable and starts the length detection, the corner detection sensor 131 begins to work. Its main task is to monitor the rotation angle data of the driving roller 107 in real time. Since the driving roller 107 directly contacts and pushes the cable forward, its rotation angle can indirectly reflect the distance the cable is transmitted. Therefore, by accurately measuring the rotation angle of the driving roller 107, the actual moving length of the cable can be very accurately calculated.

[0053] Next is the length compensation unit 132, which is the core calculation module in the entire length detection component 104. Based on the rotation angle data provided by the corner detection sensor 131, the length compensation unit 132 can calculate the length of the cable. However, considering various error factors that may occur during the actual operation process (such as wear of the driving roller 107, changes in the surface friction coefficient of the cable, etc.), the length compensation unit 132 also undertakes the task of compensating for the systematic errors of the calculated cable length. By analyzing and correcting these potential errors, it ensures that the final cable length value obtained is more accurate and reliable.

[0054] Finally, the control unit 133 is responsible for coordinating the entire length detection and cutting process. When the control unit 133 receives the information that the cable length calculated by the length compensation unit 132 reaches the preset value, it will immediately activate the cutting cylinder 111 to perform the cable cutting action. This process is highly automated and responds quickly, ensuring that each section of the cable can be accurately cut according to the preset length, greatly improving the production efficiency and product quality.

[0055] Second Embodiment

[0056] Please refer to Figure 7 , the present invention also provides a method for measuring and cutting the length of a cable, including:

[0057] S201 Pass the cable to be processed through between the driving roller 107 and the driven roller 109, and adjust the position of the adjusting plate 108 to clamp the cable;

[0058] The operator needs to accurately pass the cable to be processed through between the driving roller 107 and the driven roller 109. This step requires the cable to be correctly placed between the two rollers to ensure the stability and accuracy during the subsequent transmission process. Then, according to the specific diameter and hardness of the cable, adjust the position of the adjusting plate 108 to clamp the cable. The design of the adjusting plate 108 allows it to slide along the support frame 102 to provide an appropriate clamping force for cables of different specifications. During this process, the conical guide sleeve 126 can help guide the cable smoothly into the drive system and maintain the correct transmission direction.

[0059] S202 starts the driving roller 107 to drive the cable to move, and detects the length of the cable through the length detection component 104;

[0060] The driving roller 107 in the driving assembly 105 is started. The driving roller 107 starts to rotate, driving the cable forward. At the same time, the length detection assembly 104 starts to work. The photoelectric sensor 130 first detects the presence of the cable and triggers the length detection program. Subsequently, the angle detection sensor 131 monitors the rotation angle of the driving roller 107 in real time, and these data are transmitted to the length compensation unit 132 for calculation. The length compensation unit 132 calculates the actual length of the cable based on the rotation angle data, and compensates for possible system errors through a built-in algorithm, thereby obtaining a more accurate cable length value.

[0061] S203 When the cable length reaches a preset value, the cutting cylinder 111 is started to drive the cutting blade 110 to move downward to cut the cable.

[0062] The control unit 133 receives the signal and starts the cutting cylinder 111. The cutting cylinder 111 moves quickly, pushing the mounting block 112 mounted on its output end to move downward, and the cutting blade 110 on the mounting block 112 moves down accordingly, accurately cutting the cable. In order to ensure the efficiency and stability of the reset after each cut, the reset spring 113 in the cutting assembly 103 will automatically pull the cutting blade 110 back to the initial position after the cut is completed, ready for the next cut.

[0063] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
