[0002] In automated production, a large number of connecting wires are used, which places certain demands on the speed and efficiency of wire stripping and cutting. Currently, wire stripping and cutting can be performed using specially designed mechanical structures. However, traditional wire stripping and cutting devices suffer from insufficient automation, complex mechanical structures, and limited functionality. Existing devices require operators to manually determine the wire specifications and select the appropriate cutter during stripping; incorrect use can damage some wire cores, resulting in waste. Furthermore, existing devices are relatively inefficient. Although they can cut wires of different lengths, they rely heavily on manual operation for batch cutting of equal lengths and sections, failing to meet the needs of industrialized mass production of customized wires. Summary of the Invention
[0003] The purpose of this invention is to address the deficiencies in the existing technology by providing a fully automatic wire stripping and cutting device capable of stripping and cutting wires to a fixed length.
[0004] To achieve the above objectives, the technical solution provided by this utility model is as follows:
[0005] A fully automatic wire stripping and cutting device includes a frame, a programmable logic controller (PLC), a cutter shaft servo driver, a material shaft servo driver, an encoder at the input end of the working material shaft, an encoder at the output end of the working material shaft, a cutter shaft motor, a cutter shaft drive gear, a cutter shaft driven gear, a cutter shaft cutter blade, a material shaft motor, a working material shaft drive wheel, a working material shaft input driven wheel, a working material shaft input auxiliary driven wheel, a working material shaft output driven wheel, and a working material shaft output auxiliary driven wheel; the PLC, cutter shaft servo driver, material shaft servo driver, and working material shaft input encoder...

The cutter shaft drive gear, cutter shaft driven gear, working material shaft drive wheel, working material shaft input driven wheel, and working material shaft output driven wheel are rotatably mounted on the frame via bearings. The output shaft of the material shaft motor is connected to the working material shaft drive wheel, and the left and right sides of the working material shaft drive wheel are respectively connected to the working material shaft input driven wheel, the cutter shaft drive gear, the working material shaft drive wheel, the working material shaft input driven wheel, and the material shaft output driven wheel. The driven wheel at the output end of the working material shaft is tightly engaged; the output shaft of the cutter shaft motor is connected to the cutter shaft drive gear, and the cutter shaft drive gear meshes with the cutter shaft driven gear; the cutter includes an upper cutter and a lower cutter that can move up and down along the frame; the lower cutter and the upper cutter are respectively connected to the cutter shaft drive gear and the cutter shaft driven gear through connecting rods, each forming a set of crank-slider mechanisms; the auxiliary driven wheel at the input end of the working material shaft and the auxiliary driven wheel at the output end of the working material shaft are respectively mounted on the frame through a set of rocker-slider mechanisms, and the rocker of each set of rocker-slider mechanisms is respectively engaged with the corresponding working material shaft drive gear. The input shafts of the encoder at the input end of the feed shaft and the encoder at the output end of the working feed shaft are connected. When stripping and cutting wires, the wires to be stripped are sequentially located between the auxiliary driven wheel at the input end of the working feed shaft and the driven wheel at the input end of the working feed shaft, between the driven gear of the cutter shaft and the driving gear of the cutter shaft, and between the auxiliary driven wheel at the output end of the working feed shaft and the driven wheel at the output end of the working feed shaft. The auxiliary driven wheel at the input end of the working feed shaft and the driven wheel at the input end of the working feed shaft tightly clamp the wires to be stripped.
[0006] This invention utilizes a programmable logic controller (PLC) and encoders to control various servos, transmitting stripping and shearing commands to achieve fixed-length wire cutting or stripping. The cutter shaft motor drives the drive gear and driven gear of the cutter shaft to rotate in opposite directions, thereby opening and closing the upper and lower cutters to control the wire cutting depth for cutting or stripping. The drive wheel of the working material shaft drives the driven wheels at the input and output ends of the working material shaft to rotate in the same direction, realizing the transmission of the wire to be cut or stripped, either in the opposite direction. The encoders at the input and output ends of the working material shaft determine the linear displacement of the wire to be cut or stripped, thus achieving fixed-length wire cutting and stripping.
[0007] Furthermore, the fully automatic wire stripping and shearing device of this utility model also includes a reference material shaft input end encoder, a reference material shaft output end encoder, a reference material shaft drive wheel, a reference material shaft input end drive wheel, a reference material shaft input end auxiliary driven wheel, a reference material shaft output end driven wheel, and a reference material shaft output end auxiliary driven wheel; the reference material shaft input end encoder and the reference material shaft output end encoder are respectively fixed on the frame; the reference material shaft drive wheel, the reference material shaft input end drive wheel, and the reference material shaft output end driven wheel are rotatably mounted on the frame via bearings; the reference material shaft drive wheel is connected to the output shaft of the material shaft motor, and its left and right sides are respectively tightly connected to the reference material shaft input end driven wheel and the reference material shaft output end driven wheel.

When stripping and cutting the wire, the reference wire is sequentially located between the reference material shaft input end auxiliary driven wheel and the reference material shaft input end driven wheel, and between the reference material shaft output end auxiliary driven wheel and the reference material shaft output end driven wheel.

[0008] This invention utilizes a material shaft motor to achieve synchronous operation of the reference material shaft and the working material shaft, thereby enabling the wire to be cut and the reference wire to be cut to the same length.
[0009] Furthermore, the output shafts of the working material shaft input encoder, working material shaft output encoder, reference material shaft input encoder, and reference material shaft output encoder are respectively connected to the connecting rods of the corresponding rocker-slider mechanism via bearings; the slider parts of each rocker-slider mechanism are connected to the frame via linear bearings; and the slider ends of each rocker-slider mechanism are respectively connected to the corresponding working material shaft input auxiliary driven wheel, working material shaft output auxiliary driven wheel, reference material shaft input auxiliary driven wheel, and reference material shaft output auxiliary driven wheel via bearings.

[0020] The present invention will now be described in detail with reference to the accompanying drawings.
[0021] The technical solutions of this utility model will now be described in complete detail with reference to the accompanying drawings. Obviously, the described examples are merely a general overview of the entire utility model and do not involve detailed physical parameters of each device unit. The detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely to represent selected embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.
[0022] like Figure 1The diagram shown is a structural schematic of an automatic wire stripping and cutting device provided by this utility model. The programmable logic controller (PLC) 101 is connected to the cutter axis servo driver 102 and the material axis servo driver 103 via shielded cables, sending control commands to them. The PLC 101 is also connected to the industrial touchscreen 104 via a network cable. The industrial touchscreen writes parameters such as wire stripping and cutting mode, cutting length, and quantity to the PLC 101 via the Modbus protocol, and reads data such as the current program execution steps of the PLC. The PLC 101 is also connected to the working material axis input encoder 201, working material axis output encoder 202, reference material axis input encoder 211, and reference material axis output encoder 212 via shielded cables, reading high-speed pulses from each encoder. The cutter axis servo driver 102 is connected to the cutter axis motor 300 via a shielded cable, driving the motor to rotate and reading the current angle for closed-loop control. The material axis servo driver 103 is connected to the material axis motor 400 via a shielded cable, driving it to rotate and reading the current angle for closed-loop control.
[0023] Optionally, the programmable logic controller 101 can be connected to the industrial touch screen 104 via a shielded 485 cable.
[0024] Furthermore, both the cutter shaft drive gear 301 and the cutter shaft driven gear 302 are fixed to the frame by bearings, and only rotational motion exists. The cutter shaft drive gear 301 itself is the crank part of a set of crank-slider mechanisms mounted on the frame. During the rotation of the cutter shaft drive gear 301, it drives the lower half (lower cutter) of the cutter 303 at the end of the slider of the crank-slider mechanism to move up and down. The cutter shaft driven gear 302 itself is the crank part of another set of crank-slider mechanisms mounted on the frame. During the rotation of the cutter shaft driven gear 302, it drives the upper half (upper cutter) of the cutter 303 at the end of the slider of the crank-slider mechanism to move up and down. The output shaft of the cutter shaft motor 300 is fixedly connected to the cutter shaft drive gear 301. The cutter shaft drive gear 301 and the cutter shaft driven gear 302 mesh, and the two rotate in opposite directions without slipping, driving the lower cutter and the upper cutter to move in opposite directions or in reverse, so as to achieve complete or partial cutting of the wire 501 to be cut and stripped.
[0025] Furthermore, the working material shaft drive wheel 401, the working material shaft input end driven wheel 402, and the working material shaft output end driven wheel 404 are all fixed to the frame by bearings, and only rotational motion exists. The working material shaft drive wheel 401 is in close contact with the working material shaft input end driven wheel 402 and the working material shaft output end driven wheel 404, and under the action of friction, it drives the working material shaft input end driven wheel 402 and the working material shaft output end driven wheel 404 to rotate in the same direction.
[0026] Furthermore, the auxiliary driven wheel 403 at the input end of the working material shaft is fixed to the end of the rocker arm of a rocker-slider mechanism, allowing it to rotate and move up and down with the rocker arm. A spring is installed between the rocker arm and the frame, and is in a compressed state after installation. The spring force causes the auxiliary driven wheel 403 at the input end of the working material shaft to tend to move downwards, so that it clamps the wire to be stripped and fits tightly against the driven wheel 402 at the input end of the working material shaft. The two driven wheels rotate in opposite directions under the action of friction without slipping. The rocker arm of this rocker-slider mechanism is fixedly connected to the input shaft of the encoder 201 at the input end of the working material shaft. The rotation of the rocker arm is converted into the rotation increment of the encoder 201 at the input end of the working material shaft and read by the programmable logic controller 101.
[0027] Furthermore, when the wire to be stripped 501 is located between the driven wheel 402 at the input end of the working material shaft and the auxiliary driven wheel 403 at the input end of the working material shaft, it will generate friction under the downward pressure provided by the auxiliary driven wheel 403 at the input end of the working material shaft. It will move forward / backward with the rotation of the driven wheel 402 at the input end of the working material shaft, and the forward / backward length is consistent with the linear displacement increment of the driven wheel 402 at the input end of the working material shaft.
[0028] Furthermore, the diameter of the wire to be cut / stripped 501 is equal to the rising distance of the auxiliary driven wheel 403 at the input end of the working material shaft. Therefore, when the programmable logic controller 101 reads a rotation increment from the encoder 201 at the input end of the working material shaft, it means that the wire to be cut / stripped 501 has entered the input end of the working material shaft. When the encoder 201 at the input end of the working material shaft returns to zero, it means that the wire to be cut / stripped 501 has left the input end of the working material shaft. The rotation increment value of the encoder 201 at the input end of the working material shaft has a fixed proportional relationship with the diameter of the wire to be cut / stripped 501.
[0029] Similarly, the auxiliary driven wheel 405 at the output end of the working material shaft is fixed to the end of the rocker arm of a rocker-slider mechanism, and can rotate and move up and down with the rocker arm. A spring is installed between the rocker arm and the frame, and is in a compressed state after installation. The elastic force causes the auxiliary driven wheel 405 at the output end of the working material shaft to tend to move downward, so that it is in close contact with the driven wheel 404 at the output end of the working material shaft, and rotates in opposite directions under the action of friction without slipping. The rocker arm of the rocker-slider mechanism is fixedly connected to the encoder 202 at the output end of the working material shaft. The rotation of the rocker arm will be converted into the rotation increment of the encoder 202 at the output end of the working material shaft and read by the programmable logic controller 101.
[0030] Similarly, when the wire to be stripped 501 is located between the driven wheel 404 at the output end of the working material shaft and the auxiliary driven wheel 405 at the output end of the working material shaft, it will generate friction under the downward pressure provided by the auxiliary driven wheel 405 at the output end of the working material shaft. It will move forward / backward with the rotation of the driven wheel 404 at the output end of the working material shaft. The forward / backward length is consistent with the linear displacement increment of the driven wheel 404 at the output end of the working material shaft.
[0031] Similarly, the diameter of the wire to be stripped 501 is equal to the rising distance of the auxiliary driven wheel 405 at the output end of the working shaft. Therefore, when the programmable logic controller 101 reads a rotation increment in the encoder 202 at the output end of the working shaft, it means that the wire to be stripped 501 has entered the output end of the working shaft. When the encoder 202 at the output end of the working shaft returns to zero, it means that the wire to be stripped 501 has left the output end of the working shaft. The rotation increment value of the encoder 202 at the output end of the working shaft has a fixed proportional relationship with the diameter of the wire to be stripped 501.
[0032] Similarly, the reference material shaft drive wheel 411, the working material shaft input end driven wheel 412, and the working material shaft output end driven wheel 414 are all fixed to the frame by bearings, and only rotational motion exists. The reference material shaft drive wheel 411 is in close contact with the reference material shaft input end driven wheel 412 and the reference material shaft output end driven wheel 414, and under the action of friction, it drives the reference material shaft input end driven wheel 412 and the reference material shaft output end driven wheel 414 to rotate in the same direction.
[0033] Similarly, the relationship between the driven wheel 412 and the auxiliary driven wheel 413 at the input end of the reference material shaft is the same as the relationship between the driven wheel 402 and the auxiliary driven wheel 403 at the input end of the working material shaft. When the programmable logic controller 101 reads that the encoder 211 at the input end of the reference material shaft has a rotation increment, it means that the reference wire 502 has entered the input end of the reference material shaft. When the encoder 211 at the input end of the reference material shaft has a rotation increment that returns to zero, it means that the reference wire 502 has left the input end of the reference material shaft.
[0034] Similarly, the relationship between the driven wheel 414 and the auxiliary driven wheel 415 at the output end of the reference material shaft is the same as the relationship between the driven wheel 404 and the auxiliary driven wheel 405 at the output end of the working material shaft. When the programmable logic controller 101 reads that the encoder 212 at the output end of the reference material shaft has a rotation increment, it means that the reference wire 502 has entered the output end of the reference material shaft. When the encoder 212 at the output end of the reference material shaft has a rotation increment that returns to zero, it means that the reference wire 502 has left the output end of the reference material shaft.
[0035] This utility model automatic wire stripping and cutting device has two functions: single wire stripping and batch stripping and cutting of wires.
[0036] The batch wire stripping and cutting function has three modes: fixed length mode, same length mode, and equal division mode. Fixed length mode is used to cut wires to a preset length; same length mode is used to cut wires to the same length as the reference wire; equal division mode is used to cut a wire into a set number of equal parts.
[0037] Furthermore, all three modes of the batch wire stripping and cutting function can strip the outer sheath from both ends of the cut wires. Whether to strip and the stripping length are set by the user in the industrial touch screen 104.
[0038] Furthermore, under the batch stripping and cutting function, after the wire to be stripped enters the material shaft input end, if a wire stripping operation is set, the input end wire stripping process will be executed according to the following procedure:
[0039] Input end wire stripping process: The driven wheel 402 and the auxiliary driven wheel 403 at the input end of the working material shaft drive the wire to be stripped 501 forward to the cutter shaft, or just when the wire cutting operation is completed, it is known that the user has set the wire stripping length to be d1 mm. The programmable logic controller 101 reads the rotation increment from the encoder 201 at the input end of the working material shaft and calculates the wire radius to be R mm. According to the proportional relationship, the internal core radius is obtained as r mm. First, the upper and lower cutters separate by H mm (the initial position of the cutters is when the upper and lower parts are just closed, with a gap of 0 mm). Then, the programmable logic controller 101 drives the material shaft motor 400 to rotate forward through the material shaft servo driver 103, which drives the wire to be cut and stripped 501 forward by d1 mm. Then, the cutter shaft motor 300 is driven to rotate by a certain angle through the cutter shaft servo driver 102, so that the upper and lower parts of the cutter close (H-2r) mm and cut the wire insulation. Finally, the material shaft motor 400 is driven to rotate in the opposite direction through the material shaft servo driver 103, which moves the wire to be cut and stripped 501 backward by d1 mm to remove the wire insulation and complete the input end wire stripping process.
[0040] If the stripping operation is completed or not set, the mode setting will be checked.
[0041] Optionally, in fixed-length mode, the wire to be cut / stripped 501 is placed at the input end of the working material shaft. After the user inputs the length value, the programmable logic controller 101 drives the material shaft motor 400 to rotate forward via the material shaft servo driver 103, causing the wire to be cut / stripped 501 to advance by the set length (considering a center distance of 2D mm). The programmable logic controller 101 drives the cutter shaft motor 300 to rotate one full revolution via the cutter shaft servo driver 102, and the cutter cuts the wire 501. If a wire stripping operation is set, the output end wire stripping process is executed according to the following procedure:
[0042] Output stripping process: When the driven wheel 404 and the auxiliary driven wheel 405 at the output end of the working material shaft drive the wire to be stripped 501 back to the cutter shaft, or just when the wire cutting operation is completed, it is known that the user has set the wire stripping length to be d1 mm. The programmable logic controller 101 reads the rotation increment from the encoder 202 at the output end of the working material shaft and calculates the wire radius to be R mm, thereby obtaining the internal core radius to be r mm. First, the cutter separates by H mm (the initial position of the cutter is that the upper and lower parts are just closed, and the gap is 0 mm). Then, the programmable logic controller 101 drives the material shaft motor 400 to rotate in the opposite direction through the material shaft servo driver 103, which drives the wire to be cut and stripped 501 to move back by d1 mm. Then, the cutter shaft servo driver 102 drives the cutter shaft motor 300 to rotate by a certain angle, so that the upper and lower parts of the cutter close (H-2r) mm and cut the wire insulation. Finally, the material shaft servo driver 103 drives the material shaft motor 400 to rotate in the forward direction, which advances the wire to be cut and stripped 501 by d1 mm and removes the wire insulation to complete the wire stripping process at the output end.
[0043] Once the stripping operation is completed or not set, the process in this mode ends.
[0044] Optionally, in the same-length mode, the wire to be cut / stripped 501 is placed at the input end of the working material shaft, and the reference wire 502 is placed at the input end of the reference material shaft. The programmable logic controller 101 drives the material shaft motor 400 to rotate forward via the material shaft servo driver 103, causing the wire to be cut / stripped 501 and the reference wire 502 to move forward continuously until the rotation increment of the encoder 211 at the input end of the reference material shaft returns to zero, indicating that the reference wire 502 has been removed from the input end of the reference material shaft. Then, the working material shaft drives the wire to be cut / stripped 501 to continue moving forward by D mm. The programmable logic controller 101 drives the cutter shaft motor 300 to rotate one full revolution via the cutter shaft servo driver 102, and the cutter cuts the wire 501. If a wire stripping operation is set, the output end wire stripping process is executed according to the above procedure; if the wire stripping operation is completed or not set, this mode process ends.
[0045] Optionally, in the equal division mode, the wire to be cut and stripped 501 is placed at the input end of the working material shaft. After the user inputs the equal division value, the programmable logic controller 101 drives the material shaft motor 400 to rotate forward through the material shaft servo driver 103, causing the wire to be cut and stripped 501 to move forward continuously until the rotation increment of the encoder 201 at the input end of the working material shaft returns to zero. It is considered that the wire to be cut and stripped 501 has been removed from the input end of the working material shaft. At this time, the linear displacement increment of the driven wheel 404 at the output end of the working material shaft is the original length of the wire to be cut and stripped 501. If a stripping operation is set, the output end stripping process is executed according to the above procedure; after completion or if no stripping operation is set, the programmable logic controller 101 drives the material shaft motor 400 to rotate in the reverse direction through the material shaft servo driver 103, causing the wire to be cut and stripped 501 to retreat by the length of the equal division (considering a center distance of 2D mm). The programmable logic controller 101 drives the cutter shaft motor 300 to rotate one full revolution through the cutter shaft servo driver 102, and the cutter cuts the wire to be cut and stripped 501. At this point, the first equally divided wire is at the input end of the working material shaft, and the unequally divided wire is at the output end of the working material shaft. If a wire stripping operation is set, the input end wire stripping process is executed according to the above procedure, followed by the output end wire stripping process; after completion, or if no wire stripping operation is set, the programmable logic controller 101 drives the material shaft motor 400 to rotate in the opposite direction through the material shaft servo driver 103, causing the wire to be cut and stripped 501 to retract to the length of the equally divided wire (considering a center distance of 2D mm), repeating the above process until the equally divided wire is cut and the wire stripping operation is executed according to the setting, at which point this mode process ends.
