Description

Cable stripping system and method

Technical Field

The invention relates to the technical field of cables, in particular to a cable stripping system and a cable stripping method.

Background

In the electric power construction operation field, the cable sheath needs to be peeled off when the cable of the power supply branch box is newly installed and replaced. Because of the large cable diameter, wallpaper knives are mainly used for cutting the cable sheath at present, and the method is time-consuming and labor-consuming and is not easy to master the cutting depth. Furthermore, in extremely cold environments such as winter outdoor environments in northeast, weather is very cold and cable jackets made of polyvinyl chloride materials may become extremely stiff. In the case of the hardened cable sheath, it is very difficult to cut the cable using the wallpaper blade, and the worker needs to soften the cable sheath by heat treatment and then cut the cable sheath using the wallpaper blade. This operation significantly reduces the working efficiency and also damages the internal structure of the cable.

In addition, the cable sheath is not flat and smooth, and after being pressed or acted on by other external forces, the cable sheath may take on the form of irregularities. For example, during disassembly and replacement, the surface of the cable sheath may be bumped resulting in surface irregularities. When cutting the cable sheath using a cutting device, the cutting depth is typically set according to the thickness of the sheath exhibited by the cable end. In the whole cutting process, the initially set cutting depth cannot be applied to the whole cutting process due to the depth change caused by the unevenness of the cable sheath, and possible phenomena include: the thickness of the concave portion of the cutting depth greater than the cable easily causes the battery cell to be damaged, or the convex portion of the cutting depth less than the cable easily causes incomplete cutting.

In addition, the hardness of the cable sheath is also affected by temperature and changes occur. As the hardness of the cable sheath changes, the deformation of the cable sheath when being extruded also changes (for example, the cable sheath is soft, the deformation of the cable sheath when being extruded is large), and the setting of the cutting depth is affected by the change of the outside air temperature or the hardness of the cable sheath by the heating device.

For example, patent application publication number CN114024260a discloses a smart cable stripping device capable of autonomous travel, comprising: a fixed base, two wire clamping mechanisms and a wire stripping mechanism; the two wire clamping mechanisms are respectively and fixedly arranged at two ends above the fixed base, the wire stripping mechanism is arranged in the middle above the fixed base, and the wire stripping mechanism comprises a group of clamping mechanisms; the bottom of the fixed base is connected to a mechanical arm through a quick-change device, and the mechanical arm is arranged on the movable trolley. In the invention, because a certain angle exists between the peeling cutter and the axis of the cable, the force generated by rotation can be decomposed into a part of thrust for advancing, so that the peeling cutter can automatically advance to form a peeling path for spiral advancing. The fixing frame unit is fixed on the fixing frame mounting plate of the translation mechanism in the peeling process, the translation mechanism can translate forward simultaneously along with the spiral advancing process of the peeling cutter, after the specified peeling distance is reached, the translation mechanism controls the fixing frame unit to stop in situ, the clamping rotary cutting unit can rotate for a circle again to cut off the peeled cable skin, and then the turbine gear motor is stopped, so that the rotary motion of the clamping rotary cutting unit is stopped. However, the drawbacks of this invention include: (1) The influence of the hardness of the cable sheath on the cutting depth is not considered, and the situation that the battery core in the cable is damaged easily occurs; (2) The influence of the uneven surface of the cable sheath on the cutting depth is not considered, and the situation that the battery cells in the cable are damaged is easy to occur.

For another example, patent application publication No. CN107316722a discloses an intelligent recovery device for old cables, which comprises a base, a winding mechanism arranged on the base, a plurality of lead mechanisms arranged on the base, a peeling mechanism arranged on the base, a guiding mechanism arranged on the base, and a control mechanism arranged on one side of the base and used for coordinated control of the winding mechanism, the lead mechanisms, the peeling mechanism and the guiding mechanism, wherein a screening mechanism in signal connection with the control mechanism is arranged on the side face of the base. The working principle of the invention is as follows: moving the device to a line to be recovered, evaluating the cable, if the cable is confirmed to be required to be separated after recovery, passing the cable through a guide mechanism, and measuring the thickness of the cable sheath so as to adjust the gap between the two barking knife edges; and then the front end of the cable is placed into the auxiliary support, the cable automatically advances through a driving motor on the guide wheel set, the cable is peeled through the annular knife rest, the peeled cable skin is clamped through the control mechanism and the length of the peeled skin is determined according to the rotating speed of the driving motor on the guide wheel set. When the length can be matched with the pneumatic finger on the winding wheel, the outer skin is pulled to the pneumatic finger, the pneumatic finger is clamped, and the lead module is loosened to reset the lead module so as to play a role of auxiliary support. The corresponding winding wheel is controlled to work, the control of the rotating speed of the winding wheel is realized by controlling the contact surface between the friction plug and the friction ring, and the upper part of the winding wheel is completely wound along with the winding, so that the winding wheel is fully applied. The lead rod is contracted downwards, so that the stripped outer skin and the stripped metal wire core are wound with corresponding winding wheels, and the wire coil formed by the lead rod is a compact wire coil. Since the cable is peeled and used for recycling, the influence of the broken battery cells is not required to be considered, and the influence of the hardness of the cable sheath and the uneven surface on the cutting depth is not considered.

Therefore, how to provide a cable stripping system which can be carried and used independently, can be connected with a control unit and realize intellectualization, so that the battery core is not damaged in the process of cutting the cable sheath, and meanwhile, the stripping efficiency is higher, which is a difficult problem not yet solved at present.

Furthermore, there are differences in one aspect due to understanding to those skilled in the art; on the other hand, since the applicant has studied a lot of documents and patents while making the present invention, the text is not limited to details and contents of all but it is by no means the present invention does not have these prior art features, but the present invention has all the prior art features, and the applicant remains in the background art to which the right of the related prior art is added.

Disclosure of Invention

The prior art systems for cutting cable jackets have drawbacks including: (1) The cable sheath is hardened outside the cold room, so that the cable sheath is difficult to scratch according to the original cutting depth; (2) The partially used cable sheath is worn and has an uneven shape, so that the thickness of the cable sheath changes at a defect position, and a battery cell at the defect position is easily scratched and damaged; (3) The manual adjustment of the cutting depth is complicated, and the phenomenon of repeated adjustment is easy to occur, so that the efficiency of replacing the cable is reduced.

The prior art has developed solutions for detecting the insulation stripping depth of a cable in an electric dehider by means of a metal probe in combination with a corresponding software algorithm. For example, patent document publication No. CN112082470a discloses a device for detecting insulation layer stripping depth of a cable in an electric stripper, wherein one end of a metal probe is connected with a lower clamping block of a cutter fixing cable of the electric stripper, and the other end of the metal probe is abutted with the outer side of the cable inside the electric stripper, and the detection method of the technical scheme comprises: selecting one port, applying a high potential to the selected port, and detecting potential signals of other unselected ports; if the detected electric potentials of the ports have high-level electric potentials, a first judging signal is output, the insulation layer of the cable is judged to be completely stripped, and a first indicating signal is sent out. The metal probe of the technical scheme is connected with the port through the lead wire, and the purpose of detecting the insulation layer stripping depth of the cable in the electric stripper is achieved through a software algorithm in the controller. However, the cable cutting and peeling mode in the technical scheme is performed along the circumferential direction of the cable, only one cutting line is performed under the cutting mode, otherwise, the complete peeling of the circumferential cable coating layer cannot be realized. In addition, since the cable stripping mode in the technical scheme is annular cutting, the cutter needs to rotate around the cable and gradually approach the conductor to strip the insulating outer layer, which is obviously different from the mode of stripping along the axial direction of the cable and the specific movement mode of the blade to be realized by the invention.

In view of the shortcomings of the prior art, the present invention provides, from a first aspect, a cable stripping system comprising a cable stripper, an image acquisition portion, a piercing portion, and a control portion. The cable stripper is used for cutting the cable sheath according to the control instruction of the control part. The image acquisition part is used for acquiring 3D image information of the cable sheath. The puncturing part punctures the cable sheath in a set time and acquires puncturing parameters; the control part is used for determining hardness parameters of the cable sheath according to the puncture parameters and the puncture sample data, determining defect positions of the cable sheath according to the 3D image information, determining a preferable cutting line with a small number of passing defect positions according to the defect positions, determining first cutting depth parameters of the preferable cutting line based on the hardness parameters, and determining second cutting depth parameters of the preferable cutting line in the passing defect position section based on the hardness parameters and the defect depth parameters of the defect positions.

Preferably, the cutting line is projected on the cable sheath with visible colored light by the light-emitting portion. Preferably the cut line is a straight line along the cable axis. The preferred cut line only moves linearly and dynamically on the cable sheath during the movement of the cable along the axis without rotation, without affecting the expression of the preferred cut line. In the process of cutting the cable in the axial direction, the preferable cutting line has the function of: first, the operator is made to observe whether the blade cutting direction deviates from the position of the preferred cutting line; second, the second; the image acquisition part shoots the cutting process and can record whether the cutting position deviates from the preferable cutting line.

Compared with the prior art, the invention can determine the defect position of the cable sheath through the 3D image information acquired by the image acquisition part, can obtain the puncture parameter of the cable sheath through the puncture part, and simultaneously determine a specific preferable cutting line by combining the defect position. Based on the above distinguishing technical features, the problems to be solved by the present invention may include: how to determine the corresponding cutting parameters according to the actual conditions at different positions of the cable sheath so as to prevent damage to the battery cells. Specifically, the hardness parameter of the cable sheath is determined through the puncture parameter of the puncture part, and the defect information of the cable sheath is determined through the 3D image information, so that the cutting depth parameters of different non-defect positions and defect positions can be determined, the cable stripper can cut the cable sheath with proper cutting depth, and the damage to the battery core is avoided in the cutting process.

According to a preferred embodiment, the control part controls the piercing part to pierce at least one needle body into the cable sheath for a set time in case the cable stripper restricts the rotation of the cable. When the puncture is completed, the control unit determines the puncture parameter of the puncture unit based on the 2D image information of the needle body and its reference object acquired by the image acquisition unit. Compared with the prior art, the puncture part of the invention determines the puncture parameters of the corresponding puncture area through the image information of the puncture needle body and the reference object information thereof. Based on the above distinguishing technical features, the problems to be solved by the present invention may include: how to detect the hardness parameter of a specific part on the cable sheath. In particular, prior art methods of measuring hardness of materials require special machines to pass pressure testing to determine. This makes it impossible to test the hardness of the cable sheath in real time outdoors, and the pressure test is also easy to collapse and damage the battery cells, so that the pressure test cannot be applied to the hardness test of the cable sheath. The hardness is detected by puncturing within a set time, and the puncturing speed within the set time is limited to be a speed which does not damage the battery cell. Therefore, the invention can calculate the hardness of the cable sheath according to the penetration depth condition. Preferably, the number of the needle bodies is large and the arrangement is flexible, so that the obtained depth parameter data is large, and the problem of inaccuracy of a single parameter can be avoided. Therefore, the invention can obtain abundant puncture depth data to calculate and obtain accurate hardness parameters through the puncture of the multiple rows of needle bodies at different positions.

According to a preferred embodiment, in case the cable stripper controls the cable to rotate in the circumferential direction at a specified angle, the control part collects 3D image information of at least two circumferential angles of the cable sheath and determines the defect position, wherein the control part verifies the rotational angle of the cable in the circumferential direction based on the puncture trace of the puncture part and corrects the position parameter of the defect position based on the puncture trace.

Since the cable is a thick linear object, even if a plurality of images of the cable sheath are captured, it is difficult for the control unit to accurately determine the area range captured by each image, and the control unit cannot accurately determine the correspondence between the edge position of each image and the position of the cable sheath, which may result in a large error in the position parameter of the defect position calculated by the control unit. Therefore, the invention can calculate the defect position in each image based on the puncture mark formed by puncture by taking the puncture mark as a reference object, so that the position parameters of the obtained defect position are relatively accurate.

According to a preferred embodiment, the penetration portion comprises at least two rows of pins arranged in an axial direction, at least two rows of pins being coaxially and with an adjustable distance between them, the control portion determining the distance of separation and/or the number of rows of penetration pins depending on the cutting length parameter.

Typically, if the cable is reusable, the operator only has to cut a portion of the outer skin of the cable end. The multi-row needle body puncture has the advantages that different positions can be punctured, and the problem of inaccurate data caused by local stiffness of the cable sheath is avoided.

According to a preferred embodiment, in case the hardness parameter and/or the penetration depth parameter of the cable sheath is smaller than the set hardness threshold or penetration depth threshold, the control section sends heating parameters to the heating section in the cable stripper based on the preset cable type parameter, cutting length parameter and hardness parameter, so that the heating section heats the cable sheath to a specified temperature range. The advantage of this arrangement is that the cable sheath is heated, which promotes softening of the cable sheath, so that the hardness of the cable sheath is reduced.

According to a preferred embodiment, the control part verifies whether the hardness parameter and/or the penetration depth parameter of the cable sheath is smaller than a set hardness threshold or penetration threshold in such a way that the penetration part is controlled to penetrate the cable sheath, in case the heating of the heating part in the cable stripper is completed. The control part controls the heating part to repeatedly heat the cable sheath within the cutting length range until the hardness parameter and/or the puncture depth parameter of the cable sheath are/is not smaller than the set hardness threshold value or the puncture depth threshold value. If the cable sheath is not softened, only the cutting depth parameter is adjusted, and although the cable sheath can be scratched, the cutting time is prolonged and the blade is easily worn because the cable sheath is too hard.

In order to avoid the situation that the environmental temperature is reduced and the cable skin cannot be cut, the prior art has appeared a technical scheme of reducing the hardness of the cable insulation skin by arranging heating structures such as a heating box and an electric heating pipe. For example, patent document with publication number CN207719743U discloses a wire and cable stripper, which comprises a supporting seat, a fixing plate and a second supporting plate, wherein a first supporting plate is fixedly installed on one side of the upper surface of the supporting seat, a winding drum is rotationally connected between the first supporting plate and the second supporting plate, a heating box is fixedly installed on the rear surface of the fixing plate, an electric heating pipe is embedded into the inner wall of the other side of the heating box, a groove is formed in the lower surface of the supporting seat, and an electric hydraulic rod is fixedly installed on the inner top end of the groove. According to the technical scheme, through the warm box and the electric heating pipe, when the ambient temperature is low, the cable to be peeled is preheated, the hardness of the insulating skin of the cable is reduced, and the peeling machine is convenient to peel. However, in the technical scheme, the preheating treatment process for the insulation cover of the waste cable penetrating through the heating box does not relate to a specific heating control mode, so that specific heating completion time cannot be determined, additional energy waste is caused once the heating time is too long, and if the heating time is insufficient, the cable sheath cannot meet the expected puncture requirement.

Compared with the prior art, the cable sheath softening device can realize the softening of the cable sheath through the heating part in the cable stripper, and can verify whether the hardness parameter and/or the puncture depth parameter of the cable sheath meet the expected hardness or puncture requirement according to the mode of controlling the puncture part to puncture the cable sheath. Based on the above distinguishing technical features, the problems to be solved by the present invention may include: how to accurately control the working process of the heating part of the cable stripper so as to improve the heating and softening efficiency of the whole cable sheath. Specifically, the hardness of the cable sheath is verified by the puncture part, and whether the hardness of the cable sheath meets the requirement can be verified by the puncture parameter. Under the condition that the cable sheath is softened to meet the requirements, the cutting depth parameter is set again, so that the time for cutting the cable sheath is shortened, and the service life of the blade is prolonged. Another angle of softening the cable sheath is advantageous in that it reduces the time for an outdoor worker to hold the cable stripper, or hold the cable. In outdoor extremely cold environments, the cable is ice-cold and the device is also ice-cold. For example, the outdoor environment in northeast may even be as low as-50 degrees. Even if a worker wears warm gloves, the limbs of the worker are still easy to be frozen and stiff. Through the mode of softening the cable sheath, the time that the staff waits for the cable sheath to be scratched can be reduced to make the scratched position of cable not so cold, ice-cold impression and negative emotion when also can alleviate the staff and install the cable.

According to a preferred embodiment, in the process that the control part controls the heating part in the cable stripper to repeatedly heat the cable sheath within the cutting length range, the control part judges the temperature change of the heating area based on the infrared image information acquired by the image acquisition part, and when the temperature reaches the temperature threshold value, the control part controls the heating part to replace the heating area so as to avoid the cable sheath from being excessively softened. If the heating part is continuously heated, the cable sheath is easily excessively softened or even deformed, and the battery cells are more easily damaged. Thus, the temperature of the heated area should be monitored during heating. According to the invention, the temperature change of the heated area is judged through the infrared image of the image acquisition part, so that the local temperature of the cable sheath is prevented from being too high, and the deformation of the cable sheath is prevented.

According to a preferred embodiment, in the case where the preferred cutting line is determined, the control section controls at least one row of needles of the penetration section to penetrate the defect position so as to be able to cover the defect range, the image acquisition section acquires 2D or 3D image information of the penetration section at the defect position, the control section calculates differences in penetration parameters of the respective needles from the 2D or 3D image information of the penetration section at the defect position, and determines defect depth parameters of the defect position from the differences in penetration parameters.

In general, most of them are pit-shaped. The slight punctiform pit does not affect the cutting vibration with bias, but the larger pit can cause the blade to hurt the battery cell during cutting. Therefore, the depth of the defect position is measured by the needle of the puncture part, so that the approximate thickness of the cable sheath of the defect position is obtained, and the blade is prevented from cutting too deeply.

As described above, the puncture part of the present invention is not limited to measuring the hardness of the cable sheath, the puncture mark can also be used as a reference for the defect position, the puncture result at the defect position can also be used to evaluate the thickness of the defect position, and various data are provided for the calculation of the cutting depth.

The present invention provides from a second aspect a method of stripping a cable, the method comprising: collecting 3D image information of the cable sheath; puncturing the cable sheath within a set time and obtaining puncturing parameters; determining a hardness parameter of the cable sheath according to the puncture parameter and the puncture sample data, determining a defect position of the cable sheath according to the 3D image information, determining a preferable cutting line with a smaller number of passing defect positions according to the defect position, determining a first cutting depth parameter of the preferable cutting line based on the hardness parameter, determining a second cutting depth parameter of the preferable cutting line at a passing defect position section based on the hardness parameter and the defect depth parameter of the defect position, and cutting the cable sheath according to a control instruction of the first cutting depth parameter and/or the second cutting depth parameter.

The cable stripping method of the invention has the advantages that: the data calculation is simple and the calculation time is short. In the case of the completion of sample data storage, the penetration depth of the present invention can be determined without requiring complex calculations in practical applications. In the case of puncture marks as reference, the determination of the defect position is not repeated and simplified. Therefore, the method is simple and quick, and is more suitable for providing assistance for staff in outdoor extreme environments.

According to a preferred embodiment, the method further comprises: under the condition that the cable stripper limits the rotation of the cable, the puncture part is controlled to puncture at least one needle body into the cable sheath within a set time, and under the condition that the puncture is completed, the puncture parameters of the puncture part are determined based on the collected 2D image information of the needle body and the reference object thereof.

According to the method for determining the hardness of the cable sheath through the puncture depth, the calculated data amount is small, and as the number of the needle bodies is more than two, the puncture parameters cannot form solitary example data, so that the error is small.

Detailed Description

The following detailed description refers to the accompanying drawings.

The prior art system for cutting cable sheath 401 has drawbacks including: (1) Cable sheath 401 hardens in the cold outdoors, resulting in difficulty in ripping cable sheath 401 according to the original cutting force; (2) The partially used cable sheath 401 is worn and has an uneven shape, so that the thickness of the cable sheath 401 changes at a defect position, and a battery cell at the defect position is easily scratched and damaged; (3) Manual adjustment of the cutting depth is cumbersome and repeated adjustment is easily performed, resulting in a decrease in efficiency of replacing the cable 400.

Furthermore, the outer skin surface of the old cable becomes uneven due to abrasion, scratch by foreign objects, or bending. In the case where the old cable is reused, if the cut section is rugged, the cable sheath 401 is liable to be incompletely cut or the cell is liable to be damaged. Therefore, it is necessary to evaluate the cutting depth according to the rugged profile, which is not possible with the existing system for cutting the cable 400.

Based on the defects, the invention provides a cable stripping system and a cable stripping method. The invention also provides a cable stripping device and a data processing method thereof. The invention also provides a heating method of the cable stripping equipment. The invention also provides a cable sheath cutting method.

Example 1

The present embodiment provides a cable stripping system, as shown in fig. 1 and 2, including a cable stripper 100, an image acquisition part 200, a penetration part 300, and a control part 500. As shown in fig. 6, the image capturing portion 200 and the piercing portion 300 are both disposed on the cable stripper 100 and are both communicatively connected to the control portion 500 so that they can perform their respective functions on the cable stripper 100 under the control of the control portion 500. The image acquisition unit 200 is an imaging device for acquiring a 3D image of the cable sheath 401 under a control instruction issued by the control unit 500. Piercing unit 300 is configured to pierce cable sheath 401 and obtain piercing parameters under a control command issued by control unit 500. The control part 500 can be selected from a small integrated chip with a control program related to the invention, a central processing unit and other logic operation components, so that the control part can be directly arranged on the cable stripper 100, and the cable stripper 100 can be used as an independent and complete system for stripping cables. In another preferred embodiment, the control unit 500 is only provided with hardware (for example, ISM, wi-Fi, zigBee wireless communication module) related to the transmission and reception of control signals on the cable stripper 100, and functions such as logic operation and data processing of the control unit 500 are implemented by means of a third party platform such as a remote server, a cloud server, etc. communicatively connected to the hardware. When the third party platform is used for remotely controlling the cable stripper 100, the control part 500 can be used as a control center of a plurality of cable strippers 100 at the same time, so that the control part can give control instructions to different cable strippers 100 at different times and in different occasions.

The cable stripper 100 is used to cut the cable sheath 401 according to the control instruction of the control part 500. The image acquisition unit 200 is configured to acquire 3D image information of the cable sheath 401. Preferably, the image capturing section 200 may also capture 2D image information and infrared image information of the cable sheath 401. The image pickup section 200 may include a light emitting component, a light receiving component, and a camera component. Preferably, the image capturing section 200 may further include a microchip or a microprocessor for processing image data. In case a 3D image needs to be taken, the light emitting assembly may be a 3D structured light assembly. The 3D structure light assembly is composed of a plurality of LED lamps and infrared lamps and a combination thereof.

The 3D structured light is a light ray composed of three types of points, lines and planes. Preferably, the 3D structured light may also be an infrared light consisting of a plurality of points.

3D structured light assembly the 3D structured light assembly emits projected light to the cable 400 and receives a three-dimensional light pattern reflected by the cable 400. Specifically, when the relative positions of the image pickup assembly and the light emitting assembly are fixed, the degree of distortion of the light projected on the cable 400 depends on the depth of the surface of the object, and thus a light image having depth of the surface of the cable sheath 401 can be obtained in the 3D image information.

In case of capturing 2D images, the light emitting assembly may be illuminated by only one or a few of the light assemblies, and the 2D image information is directly captured by the image capturing assembly.

In the case of capturing an infrared image, the light emitting assembly may emit infrared light from only one or more of the light assemblies, and the image capturing assembly may capture the infrared image information directly.

Piercing portion 300 is used to pierce cable sheath 401 and obtain piercing parameters within a set time. The control part 500 is used for analyzing the cutting depth parameter of the cable stripper 100.

The control part 500 is preferably an application specific integrated chip, a processor or a server capable of running the encoding program of the cable stripping method of the present invention. Preferably, the control part 500 may further include a remote server, a cloud server, and a third party platform thereof, which are communicatively connected to their own hardware. When the computing power of the control part 500 itself is insufficient, the control part 500 may transmit the related data and its algorithm to a remote server, a cloud server and its third party platform so as to quickly obtain the computing result. In general, since the image information of the cable sheath 401 is relatively small, the computing power of the control unit 500 can satisfy the need for analysis of the image information.

The analysis principle of the control unit 500 includes: determining a hardness parameter of the cable sheath 401 according to the puncture parameter and the puncture sample data, determining a defect position of the cable sheath 401 according to the 3D image information, determining a preferred cutting line with a smaller number of passing defect positions according to the defect position, determining a first cutting depth parameter of the preferred cutting line based on the hardness parameter, and determining a second cutting depth parameter of the preferred cutting line at the passing defect position section based on the hardness parameter and the defect depth parameter of the defect position.

According to the invention, the hardness parameter of the cable sheath 401 is determined by the puncture parameter of the puncture part 300, and the defect information of the cable sheath 401 is determined by the 3D image information, so that the cutting depth parameters of different non-defect positions and defect positions can be determined, the cable sheath 401 can be cut by the cable stripper 100 at an appropriate cutting depth, and the damage to the battery core is avoided in the cutting process.

Fig. 3 to 4 are block diagrams showing a front angle, a top view angle and a side view angle of a cable stripper 100 according to the present invention, respectively. The cable stripper 100 may also be a device of other construction, only required to have the approximate function of the present invention. As shown in fig. 1 to 4, the cable stripper 100 may include a mounting portion 111, a blade 101, and a measuring portion 106. The mounting portion 111 has a semicircular plate-like structure. The mounting portion 111 is for mounting the blade 101 and the measuring portion 106. The shape of the mounting portion 111 is not limited to a semicircle, and may be a sheet of another shape as long as the function of mounting the blade can be achieved. Preferably, in the case where the blade 101 is a circular blade, the mounting portion 111 is designed in a semicircular shape, simplifying the profile of the mounting portion 111 and reducing the occupied space.

Preferably, as shown in fig. 4, the blade 101 and the driving part 121 are disposed at both sides of the mounting part 111. The rotation end of the driving part 121 penetrates the mounting part 111 and is connected to the blade 101 through the third bearing 125 so that the blade 101 is driven to rotate by the driving part 121. The driving unit 121 is electrically connected to a power source 122.

Preferably, the non-cutting direction of the blade 101 is provided with a protective cover. The protective cover is used to prevent the blade 101 from accidentally injuring the limbs of the worker. The shape of the boot matches the shape of the strap offset 101. In the case of cutting cable sheath 401, the protective cover also prevents the debris of cable sheath 401 from splashing.

The measuring section 106 is mounted on the mounting section 111 by a fourth connection assembly 126. The measuring section 106 is, for example, an arc scale. The arcuate scale enables accurate measurement of the position of the arcuate edge of the blade 101, thereby enabling a worker to intuitively determine the adjustment of the blade 101. Preferably, the non-arcuate edges of the mounting portion 111 are provided with a spacing beam 118. The limiting beam 118 is connected with a pointer 112 through a second connecting component 117. Preferably, the second connection assembly 117 also secures the second stop 105 to the stop beam 118. The second limiting portion 105 is preferably a roller structure. As shown in the enlarged partial view a of fig. 5, when cutting the cable 400, the second stopper 105 rolls on the cable sheath 401, can reduce friction, and is closely adhered to the cable sheath 401, achieving precise cutting.

Preferably, pointer 112 points to the tick mark of measurement portion 106. When the spacing beam 118 moves, the pointer 112 also moves. The limiting beam 118 moves in such a manner that one end of the limiting beam is fixed, the other end of the limiting beam rotates around the fixed end, the outline of the arc scale is set to be similar to the outline of the arc track of the pointer 112, which is scratched in the rotating process of the limiting beam 118, and the pointer 112 can be accurately indicated.

Preferably, as shown in fig. 2, a first end of the spacing beam 118 is mounted to the mounting portion 111 by a fifth connection assembly 128. The second end of the spacing beam 118 is provided with a roller 108. A second end of the spacing beam 118 is capable of contacting the surface of rotation of the roller 108.

The mounting portion 111 is also provided with a depth adjustment portion 103. The depth adjustment portion 103 is, for example, a second bracket 116 including a bolt. A first bearing 113 is provided in the middle of the bolt. The bottom of the depth adjustment portion 103 is provided with a second bearing 114. The first limiting portion 110 is used for fixing the depth adjusting portion 103. The first stopper 110 is, for example, a bolt. The first limiting portion 110 is, for example, a bolt disposed laterally. When the first limiting portion 110 rotates and abuts against the bolt in the depth adjusting portion 103, the bolt in the depth adjusting portion 103 cannot rotate and be fixed, so that the second end of the limiting beam 118 cannot move.

Preferably, as shown in fig. 2 and 4, the mounting portion 111 further includes a limit adjustment portion 102 thereon. The limit adjustment 102 includes a first bracket 115 of vertically disposed bolts and a longer adjustment bolt 119. The bolt in the limit adjusting part 102 is rotated to adjust the length for fixing the cable 400. The bottom of the limit adjustment portion 102 is provided with a cable limit portion 104. The cable stopper 104 may be a fork-shaped structure as shown in fig. 2, and may also be an arc-shaped fork at an end contacting the cable 400 for fixing the cable 400. When the adjusting bolt 119 in the limit adjusting portion 102 rotates and presses the cable limit portion 104 against the cable 400, the cable 400 cannot rotate and move.

Preferably, as shown in fig. 3, the first grip portion 107 is laterally disposed on the mounting portion 111 for serving as a handle. The second grip portion 109 is vertically disposed on the mounting portion 111 and also serves as a handle.

Other configurations of the cable stripper 100 are also possible. For example: the cable 400 may be circular or oval in position. The limit adjustment mode can adopt a spiral or hand-operated mode. The heating means of cable sheath 401 may be a resistive sheet, wire, or other heating means.

As shown in fig. 5, cable 400 includes a cable sheath 401 and an armor layer 402, with the interior of armor layer 402 being a cell.

As shown in fig. 5, the cable stripper 100 is used in the following manner: the cable 400 is placed on the base, and the bolts in the limit adjustment portion 102 are adjusted so that the cable 400 is abutted against the cable limit portion 104. The bolts in the depth adjusting portion 103 are adjusted so that the second end of the spacing beam 118 can be rotated with the first end thereof as a rotation point, and the blade 101 is adjusted by a distance from the edge of the spacing beam 118 according to the reading of the pointer 112 on the measuring portion 106. The phase difference distance is the depth of cut. After the cutting depth is determined, the first stopper 110 is rotated so that the bolt in the depth adjusting portion 103 is fixed and cannot be rotated, thereby fixing the second end of the stopper beam 118. Opening the switch 120, the driving part 121 rotates, the blade 101 rotates and cuts the cable sheath 401.

In the case where the control section 500, the image acquisition section 200, and the puncture section 300 are provided, the control section 500 controls the cable stripper 100 to cut the cable sheath 401 in the following control manner. Preferably, the control unit 500 is connected to the heating unit 129 and controls the heating mode. The heating portion 129 may be fixed or movable.

Preferably, as shown in a partial enlarged view B of fig. 5, at least one elastic member is provided between the heating portion 129 and the end portion of the limit adjusting portion 102 so that the heating end can be closely fitted to the cable sheath 401. For example, the elastic member may be a spring. The heating portion 129 may be an electrically heatable resistor sheet.

Preferably, as shown in fig. 1, the image pickup part 200 is disposed above the cable stripper 100 by a bracket. The image acquisition unit 200 is connected to the control unit 500. The control unit 500 is electrically connected to the power source 122. Preferably, the penetration portion 300 includes at least two rows of needles with adjustable positions. Each row of needles comprises at least two needles arranged in a row. The puncture part 300 is provided at the bottom of the mounting part 111. Preferably, the needling direction of the puncture part 300 is perpendicular to the photographing angle of the image pickup part 200, so that the image pickup part 200 can conveniently photograph an image of the needle of the puncture part 300 penetrating the cable sheath 401.

Preferably, the puncturing part 300 adjusts its position by a moving rod connected thereto. Preferably, the control part 500 moves the penetration part 300 and its holder by at least one motor so that the penetration part 300 and its holder can penetrate the cable sheath 401 at a designated speed and a set time, such that the impact force of the penetration part 300 penetrating the cable sheath 401 is the same. The different resistance encountered by the piercing section due to the different hardness of cable sheath 401 results in the different depth of penetration of the needle body in piercing section 300 into cable sheath 401.

According to a preferred embodiment, the control part 500 controls the piercing part 300 to pierce at least one needle body into the cable sheath 401 for a set time in case the cable stripper 100 restricts the rotation of the cable, for example, in case the cable 400 is abutted by a bolt in the limit adjustment part 102. The set time is, for example, 1 second, 5 seconds, or 10 seconds. If the speed of piercing contact with cable sheath 401 is the same, the impact force applied to cable sheath 401 by the piercing section is the same. Then, the difference in hardness can be reflected by the difference in penetration depth.

When the puncture is completed, the control unit 500 determines the puncture parameter of the puncture unit 300 based on the 2D image information of the needle body and its reference object acquired by the image acquisition unit 200.

For example, the location of the penetration depth threshold on the penetration needle is coated with a colored marking pattern. The colored marking pattern is, for example, one marking line or two marking lines. Each marker line represents a different penetration depth threshold. Preferably, the colored marking pattern is made of a reflective material, so that the colored marking pattern can be clearly recognized by the control part 500 in the generated 2D image. In this way, the amount of data calculation by the control unit 500 can be reduced, and the depth range of each needle penetration can be determined by only logical determination. The disadvantage is that the puncture parameters cannot be calculated accurately. The penetration parameter mainly refers to penetration depth and may also include penetration angle. When the acquired image is 2D image information, the control unit 500 cannot recognize the puncture angle, and only the value of the puncture depth can be obtained. When the acquired image is a 3D image, the control unit 500 recognizes the puncture angle because a stereoscopic image is formed, and thus obtains the value of the puncture depth and the puncture angle. This has the advantage that the penetration portion 300 can exclude needles with curved needle bodies and their data, thereby obtaining more accurate penetration parameters (e.g. values of penetration depth).

Preferably, the length of the needle is fixed. After the puncturing is completed, the control section 500 can calculate the puncturing depth of the puncturing based on the length of the needle body exposed to the outside of the cable sheath 401. This calculation is also relatively simple and only requires comparing the puncture parameter with the puncture sample data to be able to determine the hardness corresponding to the puncture parameter.

The puncturing direction of the puncturing unit 300 according to the present invention is not necessarily perpendicular to the imaging direction of the image capturing unit 200, and may be opposite or in the same direction.

When the puncture direction of the puncture unit 300 is the same as or opposite to the imaging direction of the image acquisition unit 200, the image acquisition unit 200 can capture a change in the distance reference object on the puncture unit 300. The control unit 500 calculates the distance between the puncture unit 300 and itself by calculating the change in the distance reference, and thereby calculates the depth of penetration, which is the change in the distance of the puncture unit 300 itself. For example, the distance reference is a fixed-size origin. According to the perspective principle, when the origin is far away from the lens, the origin in the image becomes smaller, and when the origin is close to the lens, the origin becomes larger. The size of the origin in the image corresponds to the distance between the puncture section 300 and the image pickup section 200. The depth of penetration 300 into cable sheath 401 can be estimated and calculated from the change in distance from the reference. Preferably, the thickness of cable sheath 401 is 1-3 millimeters. The length of the needle of the puncturing part 300 is not more than 2 mm. This is provided to avoid the penetration 300 from completely puncturing the cable sheath 401 and damaging the cells.

In the prior art, the hardness of a material is detected, and a special machine is required to pass a pressure test to determine the hardness. This makes it impossible to test the hardness of the cable sheath 401 in real time outdoors, and also makes it easy for the pressure test to collapse and damage the cells, so that the pressure test cannot be applied to the hardness test of the cable sheath 401. The hardness is detected by puncturing within a set time, and the puncturing speed within the set time is limited to be a speed which does not damage the battery cell. Accordingly, the present invention can calculate the hardness of the cable sheath 401 according to the penetration depth condition. Preferably, the number of the needle bodies is large and the arrangement is flexible, so that the obtained depth parameter data is large, and the problem of inaccuracy of a single parameter can be avoided. Therefore, the invention can obtain abundant puncture depth data to calculate and obtain accurate hardness parameters through the puncture of the multiple rows of needle bodies at different positions.

According to a preferred embodiment, the piercing portion 300 comprises at least two rows of pins axially aligned along the cable 400. At least two rows of needle bodies are on the same axis and have adjustable spacing distances from each other. The control unit 500 determines the spacing distance and/or the number of rows of needle bodies to be pierced based on the cutting length parameter. Preferably, the needle bodies of the different rows are mounted on the same axial line by means of a slidable mechanical assembly. Thus avoiding the occurrence of a difference in puncture angle. Preferably, the needle bodies between the different rows are moved in the axial direction of the cable 400 to effect adjustment of the separation distance. Preferably, the separation distance is in the range of 0 to 5 cm. In actual use, since the range of the separation distance is a small range, the control unit 500 performs fine adjustment on the needle bodies of different rows by the control motor of the puncture unit 300.

Typically, if the cable 400 is reusable, the operator need only cut a portion of the outer skin at the end of the cable 400. The advantage of multiple row needle penetration is that different locations can be penetrated, avoiding the problem of inaccurate data due to the localized stiffness of cable sheath 401.

According to a preferred embodiment, in case the hardness parameter and/or the penetration depth parameter of the cable sheath 401 is smaller than the set hardness threshold or penetration depth threshold, the control part 500 sends heating parameters to the heating part 129 in the cable stripper 100 based on the preset cable type parameter, the cutting length parameter and the hardness parameter, so that the heating part 129 heats the cable sheath 401 to a specified temperature range. The advantage of this arrangement is that heating of cable sheath 401 promotes softening of cable sheath 401 such that the stiffness of cable sheath 401 is reduced.

In the present invention, the smaller the stiffness parameter, the stiffer the cable sheath 401 (the reverse arrangement is also possible, the same principle). The smaller the penetration depth parameter, the stiffer the cable sheath 401. Therefore, when control unit 500 determines that cable sheath 401 is too hard, it is necessary to heat and activate heating unit 129. Preferably, the heating portion 129 is a movable heating portion. For example, the heating portion 129 is provided on a micro slide rail. The micro slide rail is connected with the micro motor so that the micro motor can control the movement of the micro slide rail, so that the heating part 129 can be repeatedly moved and movable heating can be realized. The heating portion 129 can heat an end portion or a corresponding position of the cable 400 in the axial direction of the cable 400. Preferably, the heating part 129 includes a heating block having a circular arc groove shape. The heating block is, for example, an electric heating block or the like. The provision of the heating portion 129 in the shape of a circular arc groove has an advantage in that the contact area of the heating portion 129 with the cable sheath 401 can be increased, thereby improving heating efficiency.

Preferably, the cable type parameter is stored in the control section 500 in advance, or in a database connected to the control section 500. The cutting length parameter is inputted by a worker through a terminal connected to the control unit 500. The terminal is, for example, a work terminal, a mobile phone, a smart watch, or other devices used by a worker. The devices such as a work terminal, a mobile phone, and a smart watch can run the coding program of the input port, so that the device can be connected to the control unit 500 in a wireless (e.g., bluetooth) manner and realize interaction. The control part 500 can retrieve the corresponding heating parameters from the pre-stored database, knowing the cable type parameter, the cut length parameter and the hardness parameter. Alternatively, the heating parameter is input by a worker through a terminal connected to the control unit 500. The control part 500 can control the axial moving distance of the heating part 129 on the cable 400 according to the cutting length parameter so that the cable sheath 401 within the cutting range is heated.

Preferably, the end of the heating portion 129 contacting the cable sheath 401 may not be arc-shaped groove-shaped, but may be strip-shaped. The provision of the strip shape has an advantage in that the heating part 129 heats the cable sheath 401 along the preferable cut line in the case where the preferable cut line is provided. Such heating is more efficient and the difficulty of cutting by blade 101 can be reduced by simply softening cable sheath 401 near the preferred cut line.

According to a preferred embodiment, in case the heating of the heating part 129 in the cable stripper 100 is completed, the control part 500 verifies whether the hardness parameter and/or the penetration depth parameter of the cable sheath 401 is less than a set hardness threshold or penetration threshold in such a way that the penetration part 300 is controlled to penetrate the cable sheath 401. The control unit 500 controls the heating unit 129 to repeatedly heat the cable sheath 401 within the cutting length range until the hardness parameter and/or the puncture depth parameter of the cable sheath 401 is not less than the set hardness threshold or the puncture depth threshold.

If cable sheath 401 is not softened, only the cutting depth parameter is adjusted, and although cable sheath 401 can be scratched, the cutting time is prolonged and the blade is easily worn because cable sheath 401 is too hard. The hardness of the cable sheath 401 is verified by the puncture part, and whether the hardness of the cable sheath 401 meets the requirement can be verified by the puncture parameter. Under the condition that the cable sheath 401 is softened to meet the requirements, the cutting depth parameter is set again, so that the time for cutting the cable sheath 401 is shortened, and the service life of the blade is prolonged. Another angle of softening the cable sheath 401 has the advantage of reducing the time for an outdoor worker to hold the cable stripper, or hold the cable. In outdoor extremely cold environments, the cable 400 is ice-cold and the device is also ice-cold. For example, the outdoor environment in northeast may even be as low as-50 degrees. Even if a worker wears warm gloves, the limbs of the worker are still easy to be frozen and stiff. By softening the cable sheath 401, the time for a worker to wait for the cable sheath 401 to be cut can be reduced, and the cut portion of the cable 400 is made less cold, and the cold feeling and negative emotion of the worker when installing the cable 400 can be relieved.

According to a preferred embodiment, in the process that the control part 500 controls the heating part 129 in the cable stripper 100 to repeatedly heat the cable sheath 401 within the cutting length range, the control part 500 judges the temperature change of the heating area based on the infrared image information acquired by the image acquisition part 200, and in case the temperature reaches the temperature threshold, the control part 500 controls the heating part 129 to replace the heating area so as to avoid the cable sheath 401 from being excessively softened. If the heating portion is continuously heated, the cable sheath 401 is easily excessively softened or even deformed, which makes the battery cells more easily damaged. Thus, the temperature of the heated area should be monitored during heating. The invention judges the temperature change of the heated area through the infrared image of the image acquisition part, thereby avoiding the local temperature of the cable sheath 401 from being too high and avoiding the deformation of the cable sheath 401.

According to a preferred embodiment, in the case where the preferred cutting line is determined, the control section 500 controls at least one row of needles of the piercing section 300 to pierce the defect location in such a manner as to be able to cover the defect range. For example, the cover width of a row of pins is made larger than the width of a pit. When the coverage width of one row of pins is smaller than the width of the pit, two rows of pins can be arranged in a row to form longer pins, so that the effect that the coverage width of the pins is larger than the width of the pit is realized.

The image acquisition unit 200 acquires 2D or 3D image information of the puncture unit 300 at the defect position, and the control unit 500 calculates differences in puncture parameters of the respective needles from the 2D or 3D image information of the puncture unit 300 at the defect position, and determines defect depth parameters of the defect position from the differences in puncture parameters.

In general, the defects are mostly pit-shaped. The slight punctiform pit does not affect the scribing vibration of the blade, but the larger pit can cause the blade to hurt the battery cell during scribing. Accordingly, the present invention utilizes the needle of the penetration portion to measure the depth of the defective location, thereby obtaining the approximate thickness of the cable sheath 401 at the defective location, avoiding the blade cutting too deeply. The depth of the defect position is measured by the needle of the puncture part, and the accuracy of the defect analysis of the 3D image by the control part 500 can be verified according to the requirement, so that the related algorithm in the control part 500 can be timely corrected.

As described above, the puncture 300 of the present invention is not limited to measuring the hardness of the cable sheath 401, and the puncture mark can also be used as a reference for the defect position, and the puncture result at the defect position can also be used to evaluate the thickness of the defect position, providing various data for the calculation of the cutting depth.

According to a preferred embodiment, the cable stripper 100 can also be provided with an audio player by means of which the rotation instructions are played. The rotation instruction includes a rotation direction and a rotation angle. After hearing the voice of the rotation instruction, the worker can manually rotate the cable 400 to match the image capturing behavior of the image capturing section 200.

Preferably, if a rotating assembly capable of rotating the cable 400 is provided at the bottom of the cable stripper 100, the axis of the cable 400 itself can be automatically rotated. The rotating assembly is, for example, a clamp coupled to a micro-motor. In the case that the clip rotates the cable 400, the transmission shaft of the micro motor rotates by a designated angle, so that the clip controls the cable 400 to rotate by a corresponding angle, thereby achieving automatic rotation of the cable 400. In the case where the cable stripper 100 controls the cable 400 to rotate at a specified angle in the circumferential direction, the control part 500 collects 3D image information of at least two circumferential angles of the cable sheath 401 and determines the defect position. The control part 500 verifies the rotation angle of the cable 400 in the circumferential direction based on the puncture mark of the puncture part 300, and corrects the position parameter of the defect position based on the puncture mark.

Since the cable 400 is a thick linear object, even if a plurality of images of the cable sheath 401 are captured, it is difficult for the control unit to accurately determine the area range captured by each image, and the control unit cannot accurately determine the correspondence between the edge position of each image and the position of the cable sheath 401, which may result in a large error in the position parameter of the defect position calculated by the control unit. Therefore, the invention can calculate the defect positions in each image by taking the puncture marks as reference objects based on the needle holes formed by the puncture marks in rows, so that the position parameters of the obtained defect positions are more accurate.

It should be noted that the above-described embodiments are exemplary, and that a person skilled in the art, in light of the present disclosure, may devise various solutions that fall within the scope of the present disclosure and fall within the scope of the present disclosure. It should be understood by those skilled in the art that the present description and drawings are illustrative and not limiting to the claims.
