Description

Technical Field

[0001] This invention relates to the field of cable processing equipment technology, specifically to an automatically positioning cable stripping machine. Background Technology

[0002] Wires are widely used in industry, such as industrial electrical equipment and electronic products. Currently, many wires require the outer sheath to be stripped before wiring to expose the conductors at both ends.

[0003] Existing cable stripping machines have the following problems:

[0004] (1) The wire stripping machine needs to strip a fixed length of outer sheath according to the length of the insertion. When the length of insertion is incorrect, the stripping accuracy will be reduced. At the same time, when the operator needs to operate, the wire needs to be inserted into the wire stripping machine first and then the switch is turned on, which is slow. In the Chinese patent literature, the utility model patent with application number 201210274205.X discloses a semi-automatic coaxial wire stripping machine. It has a touch rod in the horizontal hollow rotating shaft. The rear end of the touch rod is connected to a touch sensor. The machine can touch the touch rod through the wire and then trigger the switch through the touch sensor. When the wire touches the touch rod, it starts to run automatically. With this structure, when the wire is inserted with too much force, the touch rod may move too much and the touch sensor cannot be activated. At the same time, it is not convenient to accurately position the length of the wire.

[0005] (2) Before stripping the cable, it needs to be fixed by a clamping mechanism. Existing clamping mechanisms can generally only fix cables of a specific diameter. When the cable diameter increases, the clamping mechanism may wear out due to the hard clamping. Existing stripping mechanisms generally cut the outer sheath by rotation. The cable needs to be fixed at the cutting center by the clamping mechanism. When the clamping part is deformed and displaced, the cable may be offset from the cutting center, which will affect the cutting depth of the cable. This will result in some parts being cut too deep and some parts being cut too shallow, which will make it difficult to remove the outer sheath later and may even damage the inner core. Summary of the Invention

[0006] The purpose of this invention is to provide an automatically positioning cable stripping machine to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: an automatically positioning cable stripping machine, comprising a housing, electrical control components, a control panel, a rotating head disposed on the front end face of the housing, and a cutting mechanism disposed on the rotating head. A main shaft with both ends passing through it is fixed at the center of the rear end face of the rotating head. The end of the main shaft away from the rotating head extends into the interior of the housing. A rotary drive module for driving the main shaft to rotate is disposed inside the housing. A clamping mechanism for elastically holding the cable is also disposed at the front end of the rotating head. The clamping mechanism is used to clamp and fix the cable at the center of the rotating head's cutting action. A cable positioning mechanism is disposed at the center of the rotating head. The cable positioning mechanism includes an outer tube inserted into the main shaft and an inner rod movably inserted into the outer tube. Both ends of the inner rod extend to the outside of the outer tube, and one end of the inner rod extends into the rotating head. The front end of the device is fixed with a top cap, and the top cap is connected to the outer tube by an elastic support. The end of the outer tube away from the top cap is fixedly connected to the first push plate. The rear end face of the first push plate is provided with a first linear drive module that drives the first push plate to slide back and forth along the length direction of the main shaft. The side of the first push plate near the inner rod is provided with a photoelectric sensor for starting the device. The end of the inner rod near the photoelectric sensor is provided with a photoelectric baffle that matches it. In the normal state of the elastic support, the photoelectric baffle is separated from the photoelectric sensor. In the compressed state of the elastic support, the photoelectric baffle blocks the photoelectric sensor. The device switch is activated according to the dwell time of the photoelectric baffle. A position sensor for detecting the advancement length of the outer tube is provided below the outer tube. The output ends of the photoelectric sensor and the position sensor are electrically connected to the input end of the electronic control element.

[0008] Furthermore, the clamping mechanism includes a mounting plate disposed at the front end of the rotating head, two clamping members movably disposed on the mounting plate via sliders, and a flexible drive module for adjusting the distance between the two clamping members.

[0009] Furthermore, the flexible drive module includes two second swing arms, two connecting shafts, a second guide block, a second push plate, a second linear drive module, an elastic connector, a second elastic reset component, and two third swing arms. A support plate is installed inside the outer casing. The mounting plate is fixed to the support plate by a support rod. The two third swing arms and two clamping components are correspondingly mounted on the mounting plate. The bottom ends of each third swing arm are rotatably connected to the support plate via connecting shafts. The top ends of each third swing arm are movably connected to sliders on the clamping components. The end of the connecting shaft away from the third swing arm extends to the support plate. The second guide block is located on the back of the second swing arm and is fixedly connected to the top of the second swing arm. The second guide block is located on the back of the second swing arm and is used to push the bottom ends of the two second swing arms to open to both ends. The second push plate is located on the back of the second guide block and is connected to the second guide block by an elastic connector. The second linear drive module is used to push the second push plate to slide towards or away from the second guide block. The second elastic reset member is connected to the two second swing arms and is used to reset the second swing arms. When the second guide block slides away from the end of the second swing arm, it pulls the bottom ends of the two second swing arms to close.

[0010] Furthermore, a roller is rotatably provided at the bottom end of the second swing arm, and the roller is in rolling connection with the outer side wall of the second guide block.

[0011] Furthermore, a guide slide rod is fixed to the back of the second guide block, and a through hole is provided on the second push plate to accommodate the guide slide rod. The elastic connector is sleeved on the guide slide rod between the second guide block and the second push plate.

[0012] Furthermore, the feed mechanism includes a first guide block, a pusher, a first swing arm, a cutter, and a first elastic reset member. Support columns are symmetrically fixed on both sides of the front end face of the rotating head. The cutter is mounted on the end of the support column away from the main shaft via the first swing arm. The first guide block is movably sleeved on the outside of the main shaft. The pusher is used to push the first guide block to slide back and forth along the axial direction of the main shaft. One end of the first swing arm is movably connected to the cutter, and the other end of the first swing arm extends to the outside of the support column and abuts against the outer wall of the first guide block. When the first guide block slides towards the end of the first swing arm, one end of the two first swing arms opens to both sides, and the other end of the first swing arm drives the two cutters to close towards the middle. The first elastic reset member connects the two first swing arms and is used for resetting the first swing arms.

[0013] Furthermore, the pusher includes at least two push rods arranged along an axial direction parallel to the main shaft, a fixing plate connecting the two push rods, and a drive module that pushes the fixing plate to slide back and forth along the axial direction of the main shaft.

[0014] Furthermore, the first guide block has a frustum-shaped structure, and an annular groove is provided on the back of the first guide block. A roller is provided at one end of the push rod near the groove, and the roller rotates freely inside the groove.

[0015] Furthermore, the rotating head is provided with a first protective cover for covering the feed mechanism inside. The first protective cover is in communication with the inside of the outer shell. The front end face of the outer shell is provided with a second protective cover for covering the first protective cover and the clamping mechanism inside. The bottom end of the second protective cover is provided with a dust collection chamber.

[0016] Furthermore, a through hole matching the first protective cover is provided on the front end face of the outer shell, and a sealing ring is provided on the inner side wall of the through hole.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the automatically positioning cable stripper

[0018] (1) By setting a cable positioning mechanism, the length of the outer sheath to be stripped can be precisely controlled. After the cable is inserted into the interior, the device switch is automatically started according to the dwell time of the detection photoelectric baffle, reducing accidental touches and achieving high accuracy and work efficiency.

[0019] (2) By setting up a clamping mechanism, the cable to be stripped can be elastically clamped, thus making it suitable for cables of different diameters. The clamping parts are not easily damaged, so that the cable can always be aligned with the cutting center. Attached Figure Description

[0037] Example 1

[0038] Please see Figure 1-10 An embodiment of the present invention provides an automatically positioning cable stripping machine, comprising a housing 1, an electrical control element 7, a control panel 8, a rotating head 2 disposed on the front end face of the housing 1, and a feed mechanism 4 disposed on the rotating head 2. The electrical control element 7 and the control panel 8 are existing technologies, and their specific structures are not described in detail here. A main shaft 201 with two through ends is fixed at the center of the rear end face of the rotating head 2. The end of the main shaft 201 away from the rotating head 2 extends into the interior of the housing 1. A rotary drive module 3 for driving the main shaft 201 to rotate is disposed inside the housing 1. The rotary drive module 3 can be a pulley mechanism, specifically a driven wheel sleeved on the drive main shaft 201. A drive motor mounted above the drive main shaft 201 via a mounting plate, a drive wheel disposed at the output end of the drive motor, and a connecting belt connecting the drive wheel and the driven wheel are used to drive the main shaft 201 and the rotating head 2 to rotate.

[0039] Please see Figure 3 and 4The feed mechanism 4 includes a first guide block 401, a pusher 402, a first swing arm 403, a cutter 404, and a first elastic reset member 405. Support columns 202 are symmetrically fixed on both sides of the front end face of the rotating head 2, and the support columns 202 are perpendicular to the rotating head 2. The cutter 404 is mounted on the end of the support column 202 away from the main shaft 201 via the first swing arm 403. Specifically, the support column 202 is provided with a mounting groove that matches the first swing arm 403. The middle section of the first swing arm 403 is rotatably connected to the support column 202. The first guide block 401 is movably sleeved on the outside of the main shaft 201. The pusher 402 is used to push the first guide block 401 to slide back and forth along the axial direction of the main shaft 201. One end of the first swing arm 403 is movably connected to the cutter 404, and the other end of the first swing arm 403 extends to the outside of the support column 202 and is flush with the outer wall of the first guide block 401. In this embodiment, a roller is installed at one end of the first swing arm 403 near the first guide block 401. When the roller rolls on the outer wall of the first guide block 401, it can reduce friction and thus reduce wear. When the first guide block 401 slides towards the end near the first swing arm 403, one end of the two first swing arms 403 slides along the outer wall of the first guide block 401 and opens to both sides. The other end of the first swing arm 403 drives the two cutters 404 to close towards the middle. The first elastic reset member 405 connects the two first swing arms 403 and is used for the reset of the first swing arm 403. The first elastic reset member 405 is specifically a spring. When the first guide block 401 slides away from the end of the first swing arm 403, the spring resets and pulls the end of the first swing arm 403 near the first guide block 401 to close, and the cutters 404 open to both sides. Other structures can also be configured as needed.

[0040] Please see Figure 4 and 5 The pusher 402 includes at least two push rods arranged along the axial direction parallel to the main shaft 201, a fixing plate connecting the two push rods, and a drive module that pushes the fixing plate to slide back and forth along the axial direction of the main shaft 201. The drive module can specifically be a servo motor and a lead screw. The fixing plate and the lead screw are connected through a lead screw seat, and the drive module is installed in the rotary drive module 3, making the internal modules of the outer casing 1 more compact.

[0041] The first guide block 401 has a frustum-shaped structure, with one end near the first guide block 401 being the upper base and the other end being the lower base. An annular groove 4011 is provided on the back of the first guide block 401. A roller 4021 is provided at the end of the push rod near the groove 4011. The rotation axis of the roller 4021 is perpendicular to the main shaft 201. The roller 4021 can rotate freely inside the groove 4011, which can reduce wear when pushing the first guide block 401.

[0042] Please see Figure 8 , 910. The front end of the rotating head 2 is also provided with a clamping mechanism 6 for elastically clamping the cable. The clamping mechanism 6 is used to clamp and fix the cable at the center of the rotating head 2. The clamping mechanism 6 includes a mounting plate 601 set at the front end of the rotating head 2, two clamping members 602 that are movably set on the mounting plate 601 by sliders, and a flexible drive module 603 for adjusting the distance between the two clamping members 602. The cable is clamped and fixed by the two clamping members 602. The clamping members 602 are specifically V-shaped structures with openings facing each other.

[0043] The flexible drive module 603 includes two second swing arms 6031, two connecting shafts 6032, a second guide block 6033, a second push plate 6034, a second linear drive module 6035, an elastic connector 6036, a second elastic reset component 6037, and two third swing arms 6038. A support plate 604 is installed inside the outer casing 1. A mounting plate 601 is fixed to the support plate 604 via a support rod. The two third swing arms 6038 are correspondingly mounted on the mounting plate 601 with two clamping components 602. The bottom ends of each third swing arm 6038 are rotatably connected to the support plate 604 via the connecting shafts 6032, and the top ends of each third swing arm 6038 are movably connected to the sliders on the clamping components 602. The connecting shafts 6032 are located away from the third swing arms 6038. One end of the swing arm 6038 extends to the back of the support plate 604 and is fixedly connected to the top of the second swing arm 6031. The third swing arm 6038 and the second swing arm 6031 rotate coaxially via a connecting shaft 6032. The top of the third swing arm 6038 has an oblong hole. The third swing arm 6038 is connected to the slider via a positioning pin, which can slide inside the oblong hole. By adjusting the angle of rotation of the third swing arm 6038 around the connecting shaft 6032, the clamping member 602 is pushed to slide left and right, clamping or releasing the cable. The second guide block 6033 is located on the back of the two second swing arms 6031. The second guide block 6033 is specifically an isosceles trapezoidal structure, with one end near the second swing arm 6031 as the upper base and the other end as the lower base. The second push plate 6034 is used to push the bottom ends of the two second swing arms 6031 to open to both ends. The second push plate 6034 is disposed on the back of the second guide block 6033, and the second push plate 6034 and the second guide block 6033 are connected by an elastic connector 6036, which can specifically be a spring. The second linear drive module 6035 is used to push the second push plate 6034 to slide towards or away from the second guide block 6033. In this embodiment, the second linear drive module 6035 can be a servo motor and a lead screw. The second push plate 6034 and the lead screw are connected through a lead screw seat, or other drive components can be used. The second elastic reset member 6037 connects the two second swing arms 6031, and the second elastic reset member 6037 can specifically be a spring. For resetting the second swing arm 6031, when the second guide block 6033 slides away from the end of the second swing arm 6031, it pulls the bottom ends of the two second swing arms 6031 together, and the clamping member 602 opens to both sides. By setting an elastic connector 6036 between the second guide block 6033 and the second push plate 6034, the elastic connector 6036 has a certain amount of deformation. When it is necessary to clamp cables of different diameters, and the displacement of the second linear drive module 6035 is determined, the elastic connector 6036 can deform according to the pressure it receives, so as to avoid the two clamping members 602 from hard clamping the cable and causing its position to shift, which in turn causes the clamping center to shift from the cutting center, reducing the cutting accuracy. It has strong applicability.

[0044] The bottom end of the second swing arm 6031 is rotatably provided with a roller 6039, which is in rolling connection with the outer wall of the second guide block 6033. The roller 6039 and the second guide block 6033 are in rolling friction to reduce wear.

[0045] A guide slide rod is fixed to the back of the second guide block 6033. A through hole is provided on the second push plate 6034 to accommodate the guide slide rod. An elastic connector 6036 is sleeved on the guide slide rod between the second guide block 6033 and the second push plate 6034 to improve the stability of the movement of the second guide block 6033.

[0046] Please see Figure 5 , 67. A cable positioning mechanism 5 is provided at the center of the rotating head 2. The cable positioning mechanism 5 includes an outer tube 501 inserted into the main shaft 201 and an inner rod 502 movably inserted into the outer tube 501. Both ends of the inner rod 502 extend to the outside of the outer tube 501. The diameter of the outer tube 501 is approximately 6 mm, and the diameter of the inner rod 502 is approximately 1 mm. The two ends of the inner rod 502 are connected to the outer tube 501 by two copper sleeves. The inner rod 502 can slide back and forth relative to the outer tube 501 along its axial direction. Both ends of the outer tube 501 are connected to the main shaft 201 by copper sleeves. The outer tube 501 and the main shaft 201 can rotate relative to each other. One end of the inner rod 502 extends to the front end of the rotating head 2. A top cap 503 is fixedly attached to the outer tube 501, and the top cap 503 is connected to the outer tube 501 via an elastic support 504, which can be a spring. A guide rod inserted into the spring is provided on the inner side of the top cap 503, and the guide rod is then fixedly connected to the inner rod 502. The end of the outer tube 501 away from the top cap 503 is fixedly connected to the first push plate 505. A first linear drive module 506 is provided on the rear end face of the first push plate 505 to drive the first push plate 505 to slide back and forth along the length direction of the main shaft 201. The first linear drive module 506 can specifically be a servo motor and a lead screw. The first push plate 505 and the lead screw are connected via a lead screw seat. A photoelectric sensor 507 for starting the device is provided on one side near the inner rod 502. A photoelectric baffle matching the photoelectric sensor 507 is provided at the end of the inner rod 502 near the photoelectric sensor 507. In the normal state, the photoelectric baffle is separated from the photoelectric sensor 507. When the elastic support 504 is compressed, the photoelectric baffle blocks the photoelectric sensor 507, and the photoelectric sensor 507 transmits the signal to the electronic control element 7. The equipment starts peeling automatically without the need for manual start-up, improving work efficiency and preventing accidental activation. A position sensor 508 for detecting the advancement length of the outer tube 501 is provided below the outer tube 501 for precise control. The length of the cable inserted into the device is controlled to improve the accuracy of the rotary stripping process, which can reach 0.1mm. The output terminals of the photoelectric sensor 507 and the position sensor 508 are electrically connected to the input terminal of the electronic control element 7. During operation, the device switch is activated by detecting the dwell time of the photoelectric baffle. Specifically, a threshold is set for the electronic control element 7. The device switch is activated only when the photoelectric baffle blocks the photoelectric sensor 507 for a period of time. That is, when the operator inserts one end of the cable into the device, it needs to hold the top cap 503 for a certain period of time before the switch is activated for rotary stripping, reducing accidental activation and improving stripping accuracy. The dwell time can be set according to individual needs.

[0047] Please see Figure 13The rotating head 2 is provided with a first protective cover 203 for covering the feed mechanism 4 inside. The first protective cover 203 is connected to the inside of the outer shell 1. The front end face of the outer shell 1 is provided with a second protective cover 9 for covering the first protective cover 203 and the clamping mechanism 6 inside. The protective cover 9 is provided with a wire inlet hole. The bottom end of the second protective cover 9 is provided with a dust collection chamber 10 to facilitate the collection of rotary cutting debris.

[0048] Working principle: First, the cable to be cut is inserted into the middle of the two clamping parts 602 inside the protective cover 9 through the inlet hole. One end of the cable pushes the top cap 503 backward, and the top cap 503 compresses the elastic support 504. At the same time, it drives the inner rod 502 to move backward until the photoelectric baffle at the rear end of the inner rod 502 blocks the photoelectric sensor 507 and stays for a certain period of time. Then the equipment switch is automatically turned on to start working. During operation, a threshold can be set for the electronic control components according to the operator's own situation. When the photoelectric baffle blocks the photoelectric sensor 507 for a certain period of time, the equipment switch is turned on. The first linear drive module 506 can push the outer tube 501 to slide back and forth inside the spindle 201. The position of the outer tube 501 can be set in advance according to the required stripping position. The position sensor 508 can detect the position of the outer tube 501 to improve the stripping accuracy.

[0049] After the switch is turned on, the second linear drive module 6035 pushes the second push plate 6034 to slide towards the side closer to the second guide block 6033. The second push plate 6034 applies a push force to the second guide block 6033 through the elastic connector 6036, causing the bottom ends of the two second swing arms 6031 to slide along the guide slopes on both sides of the second guide block 6033 and open to both sides. The top ends of the two second swing arms 6031 drive the bottom end of the third swing arm 6038 to rotate synchronously through the connecting shaft 6032. The other end of the third swing arm 6038 drives the clamping member 602 to slide towards the middle, thereby clamping and fixing the cable at the center of the rotating head 2. When the cable diameter changes, the elastic connector 6036 has a certain amount of deformation, which prevents the clamping member 602 from being deformed and displaced due to hard clamping, which in turn causes the clamping center to shift from the cutting center.

[0050] During the feed, the pusher 402 pushes the first guide block 401 to slide along the outer wall of the spindle 201. The two first swing arms 403 open to the sides at one end near the first guide block 401, and the other end of the first swing arms 403 drives the cutter 404 to close in the middle to achieve feed. The spindle 201, the rotating head 2 and the cutter 404 are driven to rotate synchronously by the rotation drive module 3 to spin cut the outer sheath of the cable.

[0051] Example 2

[0052] Please see Figure 11-12In this embodiment, based on embodiment 1, the connection structure between the servo motor and the lead screw is as follows: the lead screw is mounted on one side of the servo motor via a bracket 12, and one end of the lead screw is fixedly connected to the output end of the servo motor via a coupling. The lead screw and the bracket 12 are connected via two bearings 13. One end of the lead screw is provided with a smooth section for mounting the bearing 13, and a step is provided at the connection between the smooth section and the lead screw.
