Description

Technical Field

[0001] This invention relates to the field of cable processing technology, and in particular to a device and method for stripping and cutting multi-core cables to a fixed length. Background Technology

[0002] The cable processing process includes steps such as core stripping, copper ring crimping, wire cutting and turning, aluminum foil removal, core stripping and core stripping, center pin crimping, and outer conductor crimping. With the development of the electronics industry, the application range of cables is increasing, and the types of cables are also increasing. Depending on the different requirements of the cables, different degrees of core stripping and core stripping are performed on the cables.

[0003] In the prior art, such as the Chinese utility model patent application CN213701583U published on May 14, 2020, a multi-core cable cutting and semi-stripping device is used to strip the core of the cable by placing the cable in the grooves on multiple sets of support blocks and using a cutter and a semi-stripping blade.

[0004] However, when implementing the above technical solution, the inventors found that when the length difference between the cables is small, the length of the support block is greater than the spacing, and the core stripping and zero cutting of the cables cannot be achieved. At present, core stripping and zero cutting devices with different lengths have become a technical problem that urgently needs to be solved. Summary of the Invention

[0005] In view of at least one of the above technical problems, the present invention provides a device and method for stripping and cutting multi-core cables of fixed length, so as to realize the stripping and cutting of multi-core cables of different lengths.

[0006] According to a first aspect of the present invention, a multi-core cable fixed-length stripping and zero-cutting device is provided, comprising:

[0007] The base has a first mounting platform on it, on which a clamping mechanism and a positioning flipping mechanism are fixedly mounted. The base also has a positioning detection mechanism and a zero-cutting mechanism.

[0008] The clamping mechanism has grippers for clamping cables;

[0009] The positioning and flipping mechanism is located on the side of the clamping mechanism with the jaws. The positioning and flipping mechanism is at the same height as the jaws, and the cable passes through the positioning and flipping mechanism.

[0010] The positioning detection mechanism can be movably arranged on the other side of the positioning and flipping mechanism. The positioning detection mechanism is used to detect whether the core is in the correct position.

[0011] The zero-cutting mechanism can be slidably positioned relative to the positioning and flipping mechanism, and the zero-cutting mechanism is used for stripping and cutting the core of the cable.

[0012] In some embodiments of the present invention, the positioning and flipping mechanism includes two connecting blocks fixedly connected to the first mounting platform, at least two positioning and flipping blocks rotatably connected between the two connecting blocks, and a first driving member for controlling the rotation of the positioning and flipping blocks. Each of the two positioning and flipping blocks has a plurality of through holes for the wire core to pass through, and the plurality of through holes are arranged corresponding to the position of the gripper.

[0013] In some embodiments of the present invention, the clamping mechanism further includes a second driving member for driving the opening and closing of the gripper, and a cable groove at the end away from the positioning and flipping mechanism, the cable groove extending toward the gripper.

[0014] In some embodiments of the present invention, the first mounting platform further includes a first lateral drive component and a first longitudinal drive component. The first lateral drive component is used to drive the first mounting platform to move closer to or away from the zero-cutting mechanism, and the first longitudinal drive component is used to drive the first mounting platform to move closer to or away from the base.

[0015] In some embodiments of the present invention, the positioning detection mechanism has a plurality of detection holes with the same number of through holes as the positioning flipping block and opposite to each other in position. One of the detection holes has a positioning detection element. The positioning detection mechanism also has a second lateral driving component and a second longitudinal driving component. The second lateral driving component is used to drive the positioning detection mechanism to move closer to or away from the flipping mechanism, and the second longitudinal driving component is used to drive the positioning detection mechanism to move closer to or away from the base.

[0016] In some embodiments of the present invention, the positioning detection mechanism also has a color recognition element for identifying the placement order of the wire cores.

[0017] In some embodiments of the present invention, the zero-cutting mechanism includes a first zero-cutting component and a second zero-cutting component. Both the first zero-cutting component and the second zero-cutting component have a zero-cutting blade assembly at one end facing the positioning and flipping mechanism. The first zero-cutting component and the second zero-cutting component are slidably connected. The second zero-cutting component also has a third driving member. The third driving member is used to drive the second zero-cutting component to slide on the first zero-cutting component. The sliding direction causes the second zero-cutting component to move closer to or away from the positioning and flipping mechanism.

[0018] In some embodiments of the present invention, the zero-cutting mechanism further includes a fourth driving member for driving the zero-cutting blade assembly to open and close, and a fifth driving member for driving the zero-cutting mechanism to move closer to or away from the positioning and flipping mechanism.

[0019] In some embodiments of the present invention, a guide plate is also fixed below the zero-cutting blade assembly, and a waste collection box is also provided below the guide plate.

[0020] According to a second aspect of the present invention, a method for stripping and cutting multi-core cables to a fixed length is also provided, comprising the following steps:

[0021] S10: Pass the multi-core cable cores through the through holes of the positioning and flipping mechanism according to the color settings, and clamp the cable with the grippers.

[0022] S20: Drive the positioning detection mechanism to make the inner core pass through the detection hole for color detection and cable positioning detection. After the detection is completed, the positioning detection mechanism exits.

[0023] S30: Based on the length requirements of each inner core, the distance between the two sets of zero-cutting blades at the front end of the first zero-cutting component and the second zero-cutting component is fixed;

[0024] S40: Flip the flip block so that the cable in a set of flip blocks faces the zero-cutting mechanism;

[0025] S50: Drives the first mounting platform to rise or fall, so that the cable in a set of flipping blocks is flush with the zero cutter group;

[0026] S60: Drive the zero-cutting mechanism to approach the positioning and flipping mechanism and perform zero-cutting on the wire core;

[0027] S70: After zero cutting, move the zero cutting mechanism away from the positioning flipping mechanism and flip the next set of flipping blocks that need to be zero cut. Repeat steps S40 to S60 until all wire cores are zero cut.

[0028] The beneficial effects of the present invention are as follows: The present invention fixes the cable through the clamping mechanism and the positioning flipping mechanism, and detects the position of the wire core through the positioning detection mechanism. During stripping, a group of wire cores on the positioning flipping mechanism is rotated, and then the zero-cutting mechanism slides in the opposite direction to the positioning flipping mechanism so that the zero-cutting mechanism strips the wire cores. Then, the other groups of wire cores that have not been stripped on the positioning flipping mechanism are rotated in sequence, and then the zero-cutting mechanism strips the wire cores.

[0040] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0042] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] like Figures 1 to 9 The multi-core cable fixed-length stripping and zero-cutting device shown includes:

[0044] The base 1 has a first mounting platform 11, on which a clamping mechanism 2 and a positioning and flipping mechanism 3 are fixedly mounted. The base 1 also has a positioning detection mechanism 4 and a zero-cutting mechanism 5. Figure 1 As shown, the clamping mechanism 2 and the positioning and flipping mechanism 3 are fixedly installed on the first mounting platform 11. The clamping mechanism 2 is used to fix the cable, the positioning and flipping mechanism 3 is used to flip multiple cables in batches to facilitate the stripping of the wire core by the zero-cutting mechanism 5, the positioning detection mechanism 4 is used to detect whether the cable is placed in a suitable position, and the zero-cutting mechanism 5 is used to strip wire cores of different set lengths.

[0045] The clamping mechanism 2 has a gripper 21, which is used to clamp the cable. For example... Figure 1 , Figure 2 As shown, the cable is held by the gripper 21. When the cable is placed into the gripper mechanism 2, the gripper 21 is driven to clamp the cable, so as to avoid the cable position shift during the flipping or stripping process, which would cause errors in the stripping result.

[0046] The positioning and flipping mechanism 3 is located on the side of the clamping mechanism 2 with the gripper 21. The positioning and flipping mechanism 3 is at the same height as the gripper 21, and the cable passes through the positioning and flipping mechanism 3. (Continue to refer to...) Figure 1 , Figure 2 As shown, the cable is fixed by the clamp 21, and the wire core passes through the positioning and flipping mechanism 3. When stripping is required, the wire core is flipped at a fixed angle by the flipping and positioning mechanism 3, so that the zero-cutting mechanism 5 can strip the cable to different lengths.

[0047] The positioning detection mechanism 4 can be movably positioned on the other side of the positioning and flipping mechanism 3. The positioning detection mechanism 4 is used to detect whether the wire core is in the correct position. Figure 1 , Figure 2 As shown, the positioning detection mechanism 4 detects the cable on the clamping mechanism 2 to check whether the cable is in the correct position. After the detection, the positioning detection mechanism 4 is withdrawn and moved to a station away from the stripping.

[0048] The zero-cutting mechanism 5 can be slidably positioned relative to the positioning and flipping mechanism 3. The zero-cutting mechanism 5 is used for zero-cutting of the cable core. Continuing as... Figure 1 , Figure 2 As shown, the zero-cutting mechanism 5 slides toward the positioning and flipping mechanism 3, causing the zero-cutting mechanism 5 to strip the cable on the positioning and flipping mechanism 3.

[0049] The present invention fixes the cable by clamping mechanism 2 and positioning flipping mechanism 3, and detects the position of the wire core by positioning detection mechanism. During stripping, a group of wire cores on positioning flipping mechanism 3 is rotated, and then the zero-cutting mechanism 5 slides in the opposite direction to positioning flipping mechanism 3 so that the zero-cutting mechanism 5 strips the wire core. Then, the other groups of wire cores that have not been stripped on positioning flipping mechanism 3 are rotated in sequence, and the zero-cutting mechanism 5 strips the wire core.

[0050] The positioning and flipping mechanism 3 is positioned opposite to the clamping mechanism 2 on the first mounting platform 11, such as... Figure 1 , Figure 2 and Figure 8 As shown, the positioning and flipping mechanism 3 includes two connecting blocks 31 fixedly connected to the first mounting platform 11, at least two positioning and flipping blocks 32 rotatably connected between the two connecting blocks 31, and a first driving member 33 for controlling the rotation of the positioning and flipping blocks 32. Each of the two positioning and flipping blocks 32 has several through holes 32a for the wire core to pass through, and the several through holes 32a are arranged corresponding to the positions of the gripper 21. The two connecting blocks 31 are fixed on the first mounting platform 11, and at least two positioning and flipping blocks 32 are rotatably mounted between the two connecting blocks 31. During stripping, the positioning and flipping blocks 32 are rotated so that one of the positioning and flipping blocks 32 faces the zero-cutting mechanism 5 for stripping. After stripping, the other positioning and flipping blocks 32 are rotated to perform the next set of cable stripping. The positioning and flipping block 32 also has several through holes 32a. After the cable is fixed by the clamping mechanism 2, the inner core passes through the through holes 32a on the positioning and flipping block 32. The through holes 32a can fix the inner core on one hand, and can also flip the inner core on the other hand. It should be noted that the first drive assembly consists of a power assembly and a transmission assembly. The power assembly can take many forms, such as a DC servo motor, an AC servo motor, or a stepper motor. The transmission assembly can also take many forms, such as ball bearings and lead screws, slide rails and sliders, chains, belts, or other types of transmission assemblies. The forms of the first lateral drive assembly 24, the first longitudinal drive assembly 25, the second lateral drive assembly 43, the second longitudinal drive assembly 44, the second drive assembly, the third drive assembly, the fourth drive assembly, and the fifth drive assembly are the same as those of the first drive assembly, and will not be described again hereafter.

[0051] The clamp 21 clamps the cable. The position of the cable may affect the stripping effect. To ensure that the position of the cable remains unchanged during the stripping process, the clamping mechanism 2 also has a second driving member 22 for driving the clamp 21 to open and close, and a cable groove 23 at the end away from the positioning and flipping mechanism 3, with the cable groove 23 extending towards the clamp 21. Figures 3 to 5 As shown, the cable groove 23 and the gripper 21 are at the same height. When the cable is placed in the cable groove 23 and the gripper 21 grips the cable, the extension direction of the cable is towards the zero-cutting mechanism 5.

[0052] The first mounting platform 11 has a clamping mechanism 2 and a positioning and flipping mechanism 3. The positioning and flipping mechanism 3 has multiple sets of positioning and flipping blocks 32. After the positioning and flipping blocks 32 are flipped, the inner core and the zero-cutting mechanism 5 are at different heights. To make the heights the same, the first mounting platform 11 also has a first horizontal drive assembly 24 and a first vertical drive assembly 25. The first horizontal drive assembly 24 is used to drive the first mounting platform 11 to move closer to or away from the zero-cutting mechanism 5, and the first vertical drive assembly 25 is used to drive the first mounting platform 11 to move closer to or away from the base 1. Figures 3 to 5 As shown, when the cable needs to be stripped after it is fixed, the first lateral drive component 24 can move the clamping mechanism 2 and the positioning flipping mechanism 3 on the first mounting platform 11 closer to or further away from the zero-cutting mechanism 5. After one set of wire cores on the positioning flipping block 32 has been stripped, when another set of wire cores needs to be stripped, the height of the wire cores is adjusted by adjusting the height of the first longitudinal drive component 25 so that the height of the wire cores is flush with the zero-cutting blade group 53 on the zero-cutting mechanism 5, and the wire cores are moved to the zero-cutting mechanism 5 by moving the first lateral drive component 24.

[0053] Position detection mechanism 4 is used to detect whether the cable is in the correct position, such as... Figure 1 , Figure 7 and Figure 9As shown, the positioning detection mechanism 4 has multiple detection holes 41, the same number and opposite in position as the through holes 32a on the positioning flip block 32. One of the detection holes 41 has a positioning detection element 42. The positioning detection mechanism 4 also has a second lateral drive assembly 43 and a second longitudinal drive assembly 44. The second lateral drive assembly 43 drives the positioning detection mechanism 4 closer to or further away from the positioning flip block 3, and the second longitudinal drive assembly 44 drives the positioning detection mechanism 4 closer to or further away from the base 1. The number of detection holes 41 is the same as that on the positioning flip block 32. After the cable on the positioning flip block 3 is fixed, the second lateral drive assembly 43 and the second longitudinal drive assembly 44 drive the inner core of the positioning flip block 32 to extend into the detection hole 41. One end of one of the detection holes 41 is provided with the positioning detection element 42. The contact between the inner core and the positioning detection element 42 distinguishes whether the cable is in position. It should be noted that the positioning detection element 42 can take many forms, such as an electromechanical sensor, a magnetic sensor, a capacitive sensor, or other sensors that can detect whether the cable is in position.

[0054] The multi-core wires are all different colors. To ensure that the stripping length of each color cable is fixed, the positioning detection mechanism 4 also has a color identification component 45 for identifying the placement order of the wire cores. Continuing... Figure 1 , Figure 2 and Figure 7 As shown, the color recognition component 45 on the positioning detection mechanism 4 can identify the color of the wire core in each detection hole 41. After the identification is successful, the positioning detection mechanism 4 retracts and proceeds to the next action. Color recognition can further improve the pass rate of cable stripping.

[0055] In some embodiments of the present invention, the zero-cutting mechanism 5 includes a first zero-cutting component 51 and a second zero-cutting component 52. Both the first zero-cutting component 51 and the second zero-cutting component 52 have a zero-cutting blade assembly 53 at one end facing the positioning and flipping mechanism 3. The first zero-cutting component 51 and the second zero-cutting component 52 are slidably connected. The second zero-cutting component 52 also has a third driving member 52a, which drives the second zero-cutting component 52 to slide on the first zero-cutting component 51. The sliding direction causes the second zero-cutting component 52 to move closer to or further away from the positioning and flipping mechanism 3. Figure 1 , Figure 2 and Figure 6 As shown, the third drive component drives the second zero-cutting component 52 to slide relative to the first zero-cutting component 51. The third drive component can make the zero-cutting knife group 53 of the first zero-cutting component 51 closer to the positioning and flipping mechanism 3 than the zero-cutting knife group 53 of the second zero-cutting component 52, or it can make the zero-cutting knife group 53 of the first zero-cutting component 51 farther away from the positioning and flipping mechanism 3 than the zero-cutting knife group 53 of the second zero-cutting component 52, or the two zero-cutting knife groups 53 can be in the same position.

[0056] Furthermore, the zero-cutting mechanism 5 also has a fourth driving member 53a for driving the opening and closing of the zero-cutting blade assembly 53, and a fifth driving member 56 for driving the zero-cutting mechanism 5 closer to or further away from the positioning and flipping mechanism 3. (Continue to refer to...) Figure 1 , Figure 2 and Figure 6 As shown, the fifth drive component moves the zero-cutting mechanism 5 closer to or further away from the positioning and flipping mechanism 3, and the fourth drive component's stroke enables the peeling and cutting of the inner core. It should be noted that the zero-cutting blade group 53 can take many forms; it can be two blades arranged opposite each other, multiple centrally symmetrical blade groups, rotatable ring-cutting blades, or other blade groups capable of zero-cutting.

[0057] The cable stripping process generates waste material. A guide plate 54 is fixed below the zero-cutting blade assembly 53, and a waste collection box 55 is located below the guide plate 54. For example... Figure 2 , Figure 6 As shown, the guide plate 54 is connected to the zero-cutting blade assembly 53. Waste material falls onto the guide plate 54 through the zero-cutting blade assembly 53 and then enters the waste collection box 55 for unified collection of waste material.

[0058] According to a second aspect of the present invention, a method for stripping and cutting multi-core cables to a fixed length is also provided, such as... Figure 10 As shown, the steps include:

[0059] S10: Pass the multi-core cable cores through the through hole 32a of the positioning and flipping mechanism 3 according to the color setting, and clamp the cable with the gripper 21.

[0060] S20: Drive the positioning detection mechanism 4 to make the inner core pass through the detection hole 41 for color detection and cable positioning detection. After the detection is completed, the positioning detection mechanism 4 exits.

[0061] S30: Based on the length requirements of each inner core, the distance between the two sets of zero-cutting blade groups 53 at the front end of the first zero-cutting component 51 and the second zero-cutting component 52 is fixed;

[0062] S40: Flip the positioning flip block 32 so that the cable in a set of positioning flip blocks 32 faces the zero-cutting mechanism 5;

[0063] S50: Drive the first mounting platform 11 to rise or fall, so that the cable in a set of flipping blocks is flush with the zero cutter group 53;

[0064] S60: Drive the zero-cutting mechanism 5 to approach the positioning and flipping mechanism 3 and perform zero-cutting on the wire core;

[0065] S70: After zero cutting, move the zero cutting mechanism 5 away from the positioning flipping mechanism 3, and flip the next set of flipping blocks that need to be zero cut. Repeat steps S40 to S60 until all wire cores are zero cut.

[0066] When the device of the present invention strips cables of different lengths, the wire core is first passed through the through hole 32a in the positioning and flipping mechanism 3, and the cable is placed into the clamping mechanism 2. The clamping mechanism 2 clamps the cable, and then the positioning detection mechanism 4 is driven to make the wire core pass into the detection hole 41 of the positioning detection mechanism 4. The positioning detection element 42 on one side of the positioning detection hole 41 detects whether the wire core is in place. After the detection is completed, the positioning detection mechanism 4 is retracted, and the first zero-cutting component 51 and the second zero-cutting component 52 are connected according to the requirements of each wire core length. The position of the two zero-cutting components 52 is set, and the positioning flipping blocks 32 are flipped so that the inner core of one set of positioning flipping blocks 32 faces the zero-cutting mechanism 5. The first mounting platform 11 is driven to rise or fall and move closer to the zero-cutting mechanism 5. The zero-cutting mechanism 5 strips the wire core. After stripping, the zero-cutting mechanism 5 is moved back, and the positioning flipping blocks 32 of other sets are rotated so that the wire core of another set faces the zero-cutting mechanism 5. The above steps are repeated to strip the wire core until all wire cores are stripped.

[0067] Those skilled in the art should understand that this invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to this invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
