Description

Technical Field

[0001] The present invention relates to the technical field of electronic equipment, and in particular to a wire feeding machine with tension control. Background Art

[0002] In the prior art, winding machines and tensioners are usually used in combination. When winding, the winding speed of the winding machine is constantly changing from the beginning to the end. The greater the winding speed, the greater the tension of the wire. When the tension of the wire reaches a certain level, it is easy to break the wire. The tensioner is used to solve the problem of increasing wire tension.

[0003] The tensioner pre-discharges the wire according to the winding speed of the winding machine, so that the tension of the wire remains constant. The tensioner is generally composed of a tension rod, a spring, and an adjustment mechanism for controlling the length of the spring. For details, please refer to the application document with publication number CN111332877A, entitled A servo tensioner for automatically adjusting the set tension: the tension is adjusted by pulling the spring to control the swing angle of the tension rod. Before use, the operator also needs to adjust the initial position of the spring and the tension rod. In addition, as people's requirements for winding accuracy continue to increase, the adjustment of tension also needs to be precise enough.

[0004] However, in the actual production and application process, for the same batch of winding machines and tensioners, due to the influence of deviation factors such as spring performance, the control parameters adjusted by the operator on one tensioner, such as the starting angle of the tension rod, are difficult to be directly transferred to other tensioners. Other tensioners still need to continuously debug the control parameters through actual winding tests. In addition, the control method using a combination of springs and adjustment mechanisms also has the problems of unstable tension, more equipment components and higher costs. Summary of the invention

[0005] The technical problem to be solved by the present invention is to propose a wire feeding machine with tension control, which can conveniently and accurately control the tension of the winding, while reducing the cost of batch equipment and the difficulty of parameter adjustment.

[0006] In order to solve the above technical problems, the technical solution adopted by the present invention is:

[0008] The tension control assembly includes a computing unit, a tension torque control mechanism and a tension torque control motor;

[0009] The tension torque control motor and the computing unit are both arranged on the wire feeding mechanism, one end of the tension torque control mechanism is arranged on the movable end of the tension torque control motor, and the other end of the tension torque control mechanism is provided with a wire passing wheel;

[0010] The main controller is electrically connected to the operation unit and the wire feeding mechanism respectively, the operation unit is electrically connected to the tension torque control motor, and the main controller is used to control the wire feeding speed of the wire feeding mechanism and control the swing angle of the tension torque control mechanism through the tension torque control motor.

[0011] The beneficial effects of the present invention are: providing a wire feeding machine with tension control, wherein a tension torque control mechanism for controlling the tension of the winding wire is arranged on the active end of the tension torque control motor, and when the winding speed of the winding machine changes, the tension torque control motor applies torque to the tension torque control mechanism to change the swing angle of the tension torque control mechanism, and combines the wire feeding speed control of the wire feeding mechanism to conveniently and accurately control the winding tension.

[0026] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0027] Please refer to Figures 1 to 3 , a wire feeding machine with tension control, comprising a main controller, a wire feeding mechanism and a tension control assembly;

[0028] The tension control assembly includes a computing unit 6, a tension torque control mechanism and a tension torque control motor 4.5;

[0029] The tension torque control motor 4.5 and the computing unit 6 are both arranged on the wire feeding mechanism, one end of the tension torque control mechanism is arranged on the movable end of the tension torque control motor 4.5, and the other end of the tension torque control mechanism is provided with a wire passing wheel 4.1;

[0030] The main controller 5 is electrically connected to the operation unit 6 and the wire feeding mechanism respectively, the operation unit 6 is electrically connected to the tension torque control motor 4.5, and the main controller 5 is used to control the wire feeding speed of the wire feeding mechanism and control the swing angle of the tension torque control mechanism through the tension torque control motor 4.5.

[0031] From the above description, it can be seen that the beneficial effects of the present invention are: providing a wire feeding machine with tension control, and setting a tension torque control mechanism for controlling the tension of the winding wire on the active end of the tension torque control motor 4.5. When the winding speed of the winding machine changes, the tension torque control motor 4.5 applies torque to the tension torque control mechanism to change the swing angle of the tension torque control mechanism. Combined with the wire feeding speed control of the wire feeding mechanism, the winding tension is conveniently and accurately controlled. Compared with the existing design of using springs and other components to control the angle of the tension torque control mechanism, the control parameters of the tension torque control motor 4.5 can be directly shared with other wire feeding machines using the tension torque control motor 4.5, thereby reducing the difficulty of parameter adjustment of multiple devices, and there is no need to set springs and control components for pulling the springs, thereby reducing equipment costs.

[0032] Further, the wire feeding mechanism includes an assembly frame;

[0033] The tension torque control motor 4.5 and the main controller 5 are both arranged in the assembly frame, and the surface of the assembly frame is provided with a mounting hole and a rotatable indicator ring 4.3.1 which is concentric with the mounting hole, and the movable end of the tension torque control motor 4.5 is arranged through the mounting hole and is connected to the end of the tension torque control mechanism away from the wire wheel 4.1;

[0034] The assembly frame is provided with a rotation control assembly 4.4 which is transmission-connected with the indicator ring 4.3.1, the ring surface of the indicator ring 4.3.1 is provided with a touch control 4.3.2, the position of the ring surface of the tension torque control mechanism corresponding to the indicator ring 4.3.1 is provided with a resistance piece 4.3.3 corresponding to the touch control 4.3.2, and the assembly frame is provided with an angle indication scale arranged around the edge of the indicator ring 4.3.1;

[0035] The main controller 5 is electrically connected to the touch control component 4.3.2 and the rotation control component 4.4 respectively.

[0036] From the above description, it can be seen that on the basis of using the tension torque control motor 4.5 to control the swing of the tension torque control mechanism, an indicator ring 4.3.1 is set to cooperate with the resistance piece 4.3.3; when the winding speed of the winding machine changes, by rotating the indicator ring 4.3.1, the position of the touch piece 4.3.2 can be pointed to the position corresponding to the angle where the tension torque control mechanism needs to be rotated, and when the tension torque control mechanism swings, only when it swings to the position where the angle needs to be rotated can the resistance piece 4.3.3 contact the touch piece 4.3.2, conversely, when the resistance piece 4.3.3 does not contact the touch piece 4.3.2, it means that the position of the tension torque control mechanism is not in place and needs to be adjusted again; in this way, a verification feedback link is provided to determine whether the angle adjustment of the tension torque control mechanism is reasonable, which can correct the control error generated by the tension torque control motor 4.5 during the frequent sudden change control process, thereby improving the control accuracy.

[0037] Furthermore, the rotation control assembly 4.4 includes a transmission shaft, a driving gear and a driven wheel;

[0038] The driven gear is mounted on a transmission shaft, one end of which is connected to a tension torque control mechanism. The transmission shaft is disposed on the assembly frame. The driving gear is disposed on a torque output shaft of the angle torque motor 4.5. A driven gear having a size matching that of the indicator ring 4.3.1 is disposed on a surface of the indicator ring 4.3.1 away from the tension torque control mechanism. The driven gear is meshedly connected with the driving gear.

[0039] From the above description, it can be seen that the indicator ring 4.3.1 is meshed with the driving wheel through the driven gear, so that the driving gear drives the indicator ring 4.3.1 to rotate. By setting a certain proportion of the number of teeth and cooperating with the servo motor 4.5 to drive, the control accuracy can be improved, and the meshing transmission also has the characteristics of simple structure and stable operation.

[0040] Furthermore, the indicator ring 4.3.1 has a circular track 4.3.4 arranged along the circular surface on the circular surface facing the tension torque control mechanism, the touch control part 4.3.2 is an elastic switch, and the touch control part 4.3.2 is arranged in the circular track 4.3.4;

[0041] One end of the abutment member 4.3.3 away from the tension torque control mechanism is slidably disposed in the circular track 4.3.4, and the abutment member 4.3.3 is abuttingly connected with the elastic switch.

[0042] From the above description, it can be known that the circular track 4.3.4 can guide and limit the movement of the resistance member 4.3.3, and at the same time facilitate the selection of the installation position of the touch member 4.3.2, ensuring that the resistance member 4.3.3 can stably contact the touch member 4.3.2 at a certain position during the movement process.

[0043] Furthermore, it also includes a swing arm limiter 4.6 and a swing arm limiter adjustment mechanism 4.7 for abutting against and limiting the swing of the tension torque control mechanism;

[0044] The swing arm limiter 4.6 is movably arranged on a side of the assembly frame where the mounting hole is located, and the movement direction of the swing arm limiter 4.6 is close to or away from the tension torque control mechanism, the swing arm limiter adjustment mechanism 4.7 is in communication connection with the main controller 5, and the swing arm limiter adjustment mechanism 4.7 is in transmission connection with the swing arm limiter 4.6;

[0045] When the touch member 4.3.2 contacts the abutment member 4.3.3, the rocker arm limiter adjustment mechanism 4.7 controls the rocker arm limiter 4.6 to move and abut against the tension torque control mechanism.

[0046] From the above description, it can be seen that when the tension torque control motor 4.5 controls the tension torque control mechanism to swing to a specific angle position, the rocker arm limiter 4.6 is moved to abut against the tension torque control mechanism to offset the force of the wire on the tension torque control mechanism during wire feeding, thereby reducing the torque output required for the tension torque control motor 4.5 to maintain the tension torque control mechanism stationary. At the same time, the movement of the rocker arm limiter 4.6 can be linked to the process of the resistance member 4.3.3 triggering the touch member 4.3.2, that is, after the tension torque control mechanism is determined to move into place, auxiliary limiting is immediately performed, so that the tension control of the entire wire feeding process is accurate and stable.

[0047] Furthermore, there are two rocker arm limiters 4.6, which are distributed on both sides of the rod body of the tension torque control mechanism on the assembly frame, and the rocker arm limiter adjustment mechanism 4.7 corresponds to the rocker arm limiter 4.6 one by one.

[0048] From the above description, it can be seen that the swing arm limiters 4.6 are arranged in both directions of the tension torque control mechanism swinging, which can prevent the tension torque control mechanism from being affected by the tension torque control motor 4.5 or the winding and causing excessive position deviation or shaking.

[0049] Furthermore, the wire feeding mechanism also includes a wire feeding wheel 2.3, a wire feeding driving member 2.4 and an anti-wire jumping mechanism 3;

[0050] The wire feeding drive 2.4 and the wire jumping prevention mechanism 3 are arranged on the assembly frame, the wire feeding wheel 2.3 is arranged on the movable end of the wire feeding drive 2.4, and the wire passing port of the wire jumping prevention mechanism 3 is opposite to the wire outlet port of the wire feeding wheel 2.3;

[0051] The main controller 5 is electrically connected to the wire feeding drive 2.4.

[0052] From the above description, it can be seen that the wire feeding mechanism is mainly provided with a basic wire feeding angle by the wire feeding wheel 2.3, and the wire jump prevention mechanism 3 limits the wire position to ensure a smooth wire feeding process.

[0053] Furthermore, there are at least two anti-wire jumping mechanisms 3.

[0054] It can be seen from the above description that the number and distribution positions of the anti-jump wire mechanisms 3 can be determined according to actual needs, so as to flexibly adjust the wiring path.

[0055] Furthermore, it also includes a display, which is arranged on the assembly rack and is electrically connected to the main controller 5.

[0056] From the above description, it can be seen that by setting up a display, the real-time tension of the wire, wire feeding speed and other data can be dynamically displayed, providing supervision convenience for the operator.

[0057] Furthermore, a mounting groove is provided inside the final assembly frame, and the tension torque control motor 4.5 and the transmission gear 4.4 are arranged in the mounting groove in a one-to-one correspondence.

[0058] From the above description, it can be seen that the overall stability of the device is improved by fixing different components in the installation groove.

[0059] Please refer to Figure 1 to Figure 2 , Embodiment 1 of the present invention is:

[0060] A wire feeding machine with tension control includes a main controller 5, a wire feeding mechanism and a tension control component; the tension control component includes a calculation unit 6, a tension torque control mechanism and a tension torque control motor 4.5; the tension torque control motor 4.5 and the calculation unit 6 are both arranged on the wire feeding mechanism, one end of the tension torque control mechanism is arranged on the movable end of the tension torque control motor 4.5, and the other end of the tension torque control mechanism is provided with a wire passing wheel 4.1; the main controller 5 is electrically connected to the calculation unit 6 and the wire feeding wheel driving motor 2.4 respectively, the calculation unit 6 is electrically connected to the tension torque control motor 4.5, and the main controller 5 is used to control the wire feeding speed of the wire feeding wheel driving motor 2.4 and control the swing angle of the tension torque control mechanism 4.2 through the tension torque control motor 4.5. The tension torque control mechanism is composed of a swing rod and a wire passing wheel 4.1 at the end of the swing rod, and the swing rod 4.2 is arranged on the swing rod base mounting mechanism 4.3. The wire feeding mechanism further includes a wire inlet hole 2.1, a damping increaser 2.2, a wire feeding wheel 2.3, a wire feeding drive 2.4 and an anti-jump wire mechanism 3; the wire feeding drive 2.4 and the anti-jump wire mechanism 3 are arranged on the assembly frame, the wire feeding wheel 2.3 is arranged on the movable end of the wire feeding drive 2.4, and the wire passing port of the anti-jump wire mechanism 3 is opposite to the wire outlet of the wire feeding wheel 2.3; the main controller 5 is electrically connected to the wire feeding drive 2.4. The anti-jump wire mechanism 3 is composed of a first wire passing wheel 3.1, a tensioning wheel 3.2 and a second wire passing wheel 3.3.

[0061] The tension torque control mechanism in this embodiment is the same as the rod used in some existing pre-wire tensioners, which are all matched with the wire feeding wheel 2.3 of the wire feeding mechanism. When the angle of the tension torque control mechanism changes, the position of the wire passing wheel 4.1 at its end relative to the wire feeding port of the wire feeding mechanism changes, thereby changing the wire outlet angle, thereby achieving a change in tension.

[0062] In this embodiment, combined with Figure 1 to Figure 2 As shown, the use process of a wire feeding machine with tension control includes:

[0063] Threading process: the wire passes through the wire entry hole 2.1 from bottom to top; passes through the damping increaser 2.2; goes around the wire feeding wheel 2.3; passes through the anti-jump wire mechanism from bottom to top, and finally passes through the wire passing wheel 4.1 at the end of the swing rod from bottom to top.

[0064] Wire feeding process: First, the main controller obtains the winding speed of the winding machine, and uses it to analyze the current required tension. Then, the main controller 5 converts it into a control quantity and sends it to the tension torque control motor 4.5. The tension torque control motor 4.5 outputs torque to the tension torque control mechanism to control the angle of the tension torque control mechanism and achieve tension adjustment. In addition, the tension torque control motor 4.5 can also analyze the current rotation angle of the tension torque control mechanism based on the current torque and other data. Finally, when the winding speed change demand of the winding machine is large, the main controller 5 not only needs to adjust the angle of the tension torque control mechanism, but also needs to adjust the wire feeding speed of the wire feeding wheel 2.3; when the wire feeding speed of the wire feeding wheel 2.3 can match the winding speed, the tension of the wire is adjusted through the tension torque control mechanism.

[0065] At the same time, in this embodiment, the tension torque control motor 4.5 adopts a damping-free motor to reduce the influence of the friction force of its rotation operation on the angle control, thereby avoiding inaccurate conversion of angle and torque.

[0066] Please refer to Figure 1 and Figure 3 , Embodiment 2 of the present invention is:

[0067] A wire feeding machine with tension control, based on the above-mentioned embodiment 1, the wire feeding mechanism includes an assembly frame and a display; the display is arranged on the assembly frame, and the display is electrically connected to the main controller 5; the tension torque control motor 4.5 and the main controller 5 are both arranged in the assembly frame, and the surface of the assembly frame is provided with a mounting hole and a rotatable indicator ring 4.3.1 which is concentric with the mounting hole, and the movable end of the tension torque control motor 4.5 is arranged through the mounting hole and is away from the wire passing wheel 4.1 of the tension torque control mechanism. The assembly frame is provided with a rotation control assembly 4.4 which is transmission-connected to the indicator ring 4.3.1, and a touch control 4.3.2 is provided on the ring surface of the indicator ring 4.3.1. A resisting piece 4.3.3 corresponding to the touch control 4.3.2 is provided at the position of the ring surface of the tension torque control mechanism corresponding to the indicator ring 4.3.1, and the assembly frame is provided with an angle indicating scale arranged around the edge of the indicator ring 4.3.1; the main controller 5 is electrically connected to the touch control 4.3.2 and the rotation control assembly 4.4 respectively. The assembly frame is composed of a mounting shell 1.1, a base and a fixing bracket 1.2, and the mounting hole is located on the mounting shell 1.1.

[0068] In this embodiment, the tension demand in the whole wire feeding process is constantly changing. Therefore, in order to improve the accuracy of the angle control performed by the tension torque control motor 4.5 each time, a control result verification process consisting of an indicator ring 4.3.1, a touch control part 4.3.2 and a resistance part 4.3.3 is set. When the tension demand is converted according to the winding speed of the winding machine, the angle that the tension torque control mechanism needs to rotate is determined according to the tension demand, so that the indicator ring 4.3.1 is controlled to drive the touch control part 4.3.2 to rotate to the corresponding position in advance, and then the tension torque control motor 4.5 controls the tension torque control mechanism to rotate a certain angle, and the resistance part 4.3.3 also moves accordingly. After the control action of the tension torque control motor 4.5 is completed, if the angle of the tension torque control mechanism is consistent with the expectation, the touch control part 4.3.2 will inevitably contact the resistance part 4.3.3, and the main controller 5 will receive the signal sent by the touch control part 4.3.2. If not, it means that there is a deviation in the angle of the current tension torque control mechanism, and it needs to be adjusted again to ensure that the tension torque control mechanism can reach the specified position after each winding speed change, ensure that the tension of the line meets the actual winding demand, improve the winding quality, and the current control situation can be understood in real time through the scale outside the indicator ring 4.3.1, providing an external reference for the operator.

[0069] The rotation control assembly 4.4 includes a transmission shaft, a driving wheel and a driven gear; the transmission shaft is arranged on the assembly frame, the driving gear is arranged on the rotating movable end of the servo motor 4.5, and a driven gear whose size matches that of the indicator ring 4.3.1 is arranged on the side of the indicator ring 4.3.1 away from the tension torque control mechanism, and the driven gear is meshed and connected with the driving gear. An installation groove is arranged inside the assembly frame, and the tension torque control motor 4.5 and the transmission shaft are arranged in the installation groove one by one.

[0070] In addition, in order to make the touch part 4.3.2 and the resistance part 4.3.3 contact stably, the indicator ring 4.3.1 has a circular track 4.3.4 arranged along the ring surface on the ring surface facing the tension torque control mechanism, and the touch part 4.3.2 is an elastic switch, and the touch part 4.3.2 is arranged in the circular track 4.3.4; the end of the resistance part 4.3.3 away from the tension torque control mechanism is slidably arranged in the circular track 4.3.4, and the resistance part 4.3.3 is in contact with the elastic switch. In addition, the touch part 4.3.2 can also be other touch-type sensing parts with alternative self-reset functions.

[0071] Please refer to Figure 2 and Figure 3 , Embodiment 3 of the present invention is:

[0072] A wire feeding machine with tension control, based on the above-mentioned embodiment 2, further includes a rocker arm limiter 4.6 and a rocker arm limiter adjustment mechanism 4.7 for abutting against and limiting the swing of a tension torque control mechanism; the rocker arm limiter 4.6 is movably arranged on a side where the mounting hole on the assembly frame is located, and the moving direction of the rocker arm limiter 4.6 is close to or away from the tension torque control mechanism, the rocker arm limiter adjustment mechanism 4.7 is communicated with the main controller 5, and the rocker arm limiter adjustment mechanism 4.7 is transmission-connected to the rocker arm limiter 4.6; when the touch component 4.3.2 contacts the resistance component 4.3.3, the rocker arm limiter adjustment mechanism 4.7 controls the rocker arm limiter 4.6 to move and abut against the tension torque control mechanism.

[0073] In this embodiment, the contact between the touch control part 4.3.2 and the resistance part 4.3.3 serves as a trigger signal for controlling the movement of the rocker arm limiter 4.6, which means that the tension torque control mechanism is adjusted into place. At this time, the rocker arm limiter adjustment mechanism 4.7 drives the rocker arm limiter 4.6 to move and abut against the tension torque control mechanism to achieve auxiliary fixation of the tension torque control mechanism.

[0074] In this embodiment, there are two swing bar limiters 4.6 and they are distributed on both sides of the rod body of the tension torque control mechanism on the assembly frame, and the swing bar limiter adjustment mechanism 4.7 corresponds to the swing bar limiter 4.6 one by one. In addition, as a preferred arrangement, a long strip-shaped sliding hole can be set on the assembly frame, and the swing bar limiter 4.6 is slidably set on the sliding hole, and the swing bar limiter adjustment mechanism 4.7 is a push rod motor, which is used to drive the swing bar limiter 4.6 to slide. In addition, a screw rod can also be set in the assembly frame, and the swing bar limiter 4.6 converts the rotational motion into linear motion through thread transmission.

[0075] In summary, the present invention provides a wire feeding machine with tension control, in which a tension torque control mechanism for controlling the tension of the winding wire is arranged on the active end of the tension torque control motor. When the winding speed of the winding machine changes, the tension torque control motor applies torque to the tension torque control mechanism to change the swing angle of the tension torque control mechanism. Combined with the wire feeding speed control of the wire feeding mechanism, the winding tension is conveniently and accurately controlled. Compared with the existing design of using springs and other components to control the angle of the tension torque control mechanism, the control parameters of the tension torque control motor can be directly shared with other wire feeding machines using tension torque control motors. At the same time, indicator rings, touch controls and other components are arranged to form secondary verification of the angle adjustment to ensure that the adjustment process is stable and correct. By setting a swing arm limiter and using it in conjunction with the angle verification process, the energy consumption of the motor is reduced, and the difficulty of parameter adjustment of multiple devices is reduced. There is no need to set springs and control components for pulling the springs, thereby reducing equipment costs.
