Description

Technical Field

[0001] This utility model belongs to the technical field of wire feeding equipment, specifically relating to an integrated wire feeding, stripping, and shearing machine. Background Technology

[0002] The ignition needle consists of an ignition needle electrode and a wire, which need to be soldered together. In automated ignition needle processing equipment, the wire also needs to be automatically fed, stripped, and cut. In existing equipment, these processes are completed by different machines, which leads to various wire malfunctions during the process, such as poor wire feeding, or the need for more conveying equipment to connect different machines. This results in an inefficient automated production line, increased production and maintenance costs, and a potential impact on production efficiency. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide an integrated wire stripping and cutting machine to solve the technical problem that the wires of ignition needles in the prior art need to be fed, stripped and cut by multiple devices, which increases the production and maintenance costs.

[0004] The technical solution of this utility model to solve the above-mentioned technical problems is as follows: A wire stripping and shearing integrated machine, comprising:

[0005] A frame, the frame including a vertical plate and a protective cover fitted over the vertical plate;

[0006] A straightening wheel assembly, wherein the straightening wheel assembly is disposed at the inlet end on the front side of the upright plate;

[0007] A stepping wheel assembly is provided on the vertical plate, and the stepping wheel assembly is correspondingly provided at the cable outlet end of the straightening wheel assembly;

[0008] A stripping and shearing integrated assembly is disposed on the upright plate, and correspondingly disposed at the output end of the stepper wheel assembly.

[0009] This invention integrates feeding, peeling, and trimming functions into a single device, which can reduce production and maintenance costs and improve production efficiency.

[0010] Furthermore, the straightening wheel assembly includes at least one set of horizontal straightening wheels and at least one set of vertical straightening wheels.

[0011] The benefits of this step include: multi-angle straightening to ensure the straightening effect.

[0012] Further: the stepper wheel assembly includes:

[0013] A stationary wheel is mounted on the front side of the vertical plate via a stationary wheel shaft.

[0014] A moving wheel is mounted on a rotating block via a moving wheel shaft. The rotating block is mounted on the front of the upright plate via a rotating block shaft, and the rotating block has a cavity. Both the moving wheel shaft and the rotating block shaft are equipped with gears, and the two gears mesh.

[0015] A rotation control assembly is disposed on the rotating block;

[0016] A stepper motor is provided on the front side of the upright plate. The output shaft of the stepper motor passes through the upright plate to the back side of the upright plate, and the output shaft of the stepper motor is simultaneously connected to the stationary wheel shaft and the rotating block shaft by belt drive or chain drive.

[0017] The advantages of this step are: the wire is fed through the cooperation of the stationary and moving wheels, and the stepper motor has better control precision, resulting in more accurate wire length delivery. Combined with the subsequent stripping and cutting assembly, the stripping work can be completed precisely. The moving wheel can adjust the distance between itself and the stationary wheel through the rotating block, making it suitable for wires of different diameters.

[0018] Further: the rotation control assembly includes:

[0019] A connecting plate, one end of which is disposed on the rotating block, and the other end of which is connected to the front of the upright plate by a spring;

[0020] A handwheel push rod, comprising a handwheel and a push rod, wherein the push rod is horizontally arranged, one end of the push rod is threaded to the handwheel, and the other end of the push rod abuts against the connecting plate;

[0021] The handwheel is connected to the inner wall of the protective cover via a fixing block, and the handwheel extends out of the protective cover.

[0022] The beneficial effects of this step are: by rotating the handwheel, the length of the extended push rod can be adjusted, thereby adjusting the rotation angle of the connecting plate and thus achieving the purpose of adjusting the position of the moving wheel.

[0023] Furthermore, a knob is also provided, which is located on the protective cover. The inner side of the knob is provided with two eccentric pillars, which are located on the vertical central axis and are evenly distributed on both sides of the center point. The lower eccentric pillar is axially connected to the protective cover, and the upper eccentric pillar is provided with a bearing, which abuts against the inner top surface of the connecting plate.

[0024] The benefits of this step are as follows: Although the position of the connecting plate can also be adjusted using the aforementioned push rod, long-term use of the push rod to directly adjust the position of the connecting plate will cause wear on the threads of the push rod, affecting the adjustment accuracy. However, by using the knob to push the connecting plate to the top dead center before the rotation control component operates, the rotation control component can adjust the extension length of the push rod without load, avoiding excessive wear on the threads of the push rod.

[0025] Furthermore: the integrated stripping and shearing assembly includes:

[0026] Tool holder slot plate, wherein the tool holder slot plate is disposed on the vertical plate;

[0027] Tool holder frame plate, the tool holder frame plate being fixedly disposed in the movable groove of the tool holder slot plate;

[0028] The tool holder movable plate is also located in the movable groove of the tool holder slot plate, and the tool holder movable plate moves up and down through a gear and rack assembly;

[0029] The lower cutting edge is located at the bottom of the tool holder frame plate, and the cutting edge of the lower cutting edge faces upward;

[0030] The upper cutting edge is located at the bottom of the movable plate of the tool holder, and the cutting edge of the upper cutting edge faces downward.

[0031] The cutting edges of both the upper and lower cutting edges are V-shaped, and the upper and lower cutting edges are positioned correspondingly.

[0032] A shearing motor is also located on the front side of the upright plate. The output shaft of the shearing motor passes through the upright plate to the back side of the upright plate and is connected to the gear and rack assembly via belt drive or chain drive.

[0033] The benefits of this step are: the shearing function is achieved through the gear and rack assembly, and the peeling function is completed in conjunction with the stepper assembly.

[0034] Furthermore, the output shaft of the shear motor is also equipped with a position sensor or an angle encoder.

[0035] The beneficial effects of this step are: by controlling the rotation range of the shearing motor through a position sensor or angle encoder, the stroke of the movable plate of the cutter head can be controlled.

[0036] Furthermore, the front and rear ends of the stepper wheel assembly are also equipped with cable protection tubes.

[0037] The beneficial effect of this step is that the conduit protects the wires.

[0038] Furthermore, a wire feeding guide component is provided after the wire exit end of the stripping and shearing integrated assembly. The wire feeding guide component includes a guide block, and a tapered hole is opened on the side of the guide block facing the stripping and shearing integrated assembly.

[0039] The benefits of this step are: the cut wire end is in a free state and may become skewed; in order to allow the wire to smoothly enter the subsequent wire feeding process, the tapered hole of the guide block has the function of guiding the wire end.

[0040] The beneficial effects of this utility model are:

[0041] This application integrates equipment with functions such as wire feeding, stripping, and cutting into a single device, which not only ensures the smooth and seamless operation of the above processes, but also reduces production and maintenance costs and improves production efficiency.

[0061] Example

[0062] like Figures 1-6 As shown, the present invention provides an integrated wire stripping and shearing machine, comprising:

[0063] The frame includes a vertical plate 1 and a protective cover 2 sleeved on the vertical plate 1;

[0064] Straightening wheel assembly 3, the straightening wheel assembly 3 is disposed at the inlet end on the front side of the upright plate 1;

[0065] Stepping wheel assembly 4, which is disposed on the vertical plate 1 and correspondingly disposed at the cable outlet end of the straightening wheel assembly 3;

[0066] The stripping and shearing integrated assembly 5 is disposed on the upright plate 1 and correspondingly disposed at the output end of the stepper wheel group 4.

[0067] This invention integrates feeding, peeling, and trimming functions into a single device, which can reduce production and maintenance costs and improve production efficiency.

[0068] Based on the above technical solution, the straightening wheel assembly 3 includes at least one set of horizontal straightening wheels and at least one set of vertical straightening wheels.

[0069] The straightening wheels at different angles straighten the wires from multiple angles to ensure the straightening effect.

[0070] Based on the above technical solution, the stepper wheel set 4 includes:

[0071] A stationary wheel 41 is mounted on the front side of the vertical plate 1 via a stationary wheel shaft.

[0072] A movable wheel 42 is mounted on a rotating block 43 via a movable wheel shaft. The rotating block 43 is mounted on the front of the upright plate 1 via a rotating block shaft 431 and has a cavity. Gears 421 are provided on both the movable wheel shaft and the rotating block shaft 431. The two gears 421 mesh, and the rotating block 43 rotates around the rotating block shaft 431 as the center, which can adjust the position of the movable wheel 42.

[0073] A rotation control component 44 is provided on the rotating block 43, and the rotation control component 44 controls the rotation amplitude of the rotating block 43;

[0074] A stepper motor 45 is located on the front side of the upright plate 1. The output shaft of the stepper motor 45 passes through the upright plate 1 to the back side of the upright plate 1. The output shaft of the stepper motor 45 is simultaneously connected to the stationary wheel shaft and the rotating block shaft 431 via belt drive or chain drive. In this embodiment, belt drive is preferred, and the belt used for belt drive is a synchronous toothed belt. The drive pulley is adapted to the synchronous toothed belt. The stationary wheel 41 and the moving wheel 42 rotate in opposite directions.

[0075] The wire is fed through the cooperation of the stationary wheel 41 and the moving wheel 42. The stepper motor 45 has better control precision and the length of the wire fed is more accurate. With the subsequent stripping and cutting integrated component 5, the stripping work can be completed accurately. The moving wheel 42 can adjust the distance between itself and the stationary wheel 41 through the rotating block 43, which is suitable for wires of different diameters.

[0076] like Figure 7 and Figure 8 As shown, based on the above technical solution, the rotation control component 44 includes:

[0077] A connecting plate 441, one end of which is mounted on the rotating block 43, and the other end of which is connected to the front of the upright plate 1 via a spring 442;

[0078] The handwheel push rod includes a handwheel 443 and a push rod 444. The push rod 444 is horizontally arranged. One end of the push rod 444 is connected to the handwheel 443 by a thread, and the other end of the push rod 444 abuts against the inner side of the connecting plate 441. The handwheel 443 has a threaded hole at its center, and the push rod 444 is screwed into the threaded hole.

[0079] The handwheel 443 is connected to the inner wall of the protective cover 2 via a fixing block, and the handwheel 443 extends out of the protective cover 2.

[0080] By rotating the handwheel 443, the length of the extended push rod 444 is adjusted, thereby adjusting the rotation angle of the connecting plate 441, and thus achieving the purpose of adjusting the position of the moving wheel 42. To facilitate the rubbing of the handwheel 443, the circumference of the handwheel 443 is knurled.

[0081] Based on the above technical solution, a knob 445 is also provided. The knob 445 is located on the protective cover 2. The inner side of the knob 445 is provided with two eccentric pillars. The two eccentric pillars are located on the vertical central axis and are evenly distributed on both sides of the center point. The lower eccentric pillar is axially connected to the protective cover 2 and has this eccentric pillar as the center of rotation. The upper eccentric pillar is provided with a bearing 446, which abuts against the inner top surface of the connecting plate 441. The bearing 446 and the connecting plate 441 have rolling friction, which can reduce adjustment resistance.

[0082] Under normal circumstances, although the position of the connecting plate 441 can be adjusted by adjusting the aforementioned push rod 444, long-term use of the push rod 444 to directly adjust the position of the connecting plate 441 will cause wear on the threads of the push rod 444, affecting the adjustment accuracy. However, by using the knob 445 to push the connecting plate 441 to the top dead center before the rotation control component 44 starts working, the rotation control component 44 can adjust the extension length of the push rod 444 without load, thus avoiding excessive wear on the threads of the push rod 444.

[0083] Based on the above technical solution, the integrated stripping and shearing assembly 5 includes:

[0084] Tool holder slot plate 51, the tool holder slot plate 51 is disposed on the vertical plate 1;

[0085] Tool holder frame plate 52, which is fixedly disposed in the movable groove of the tool holder slot plate 51;

[0086] The tool holder movable plate 53 is also located in the movable groove of the tool holder slot plate 51. One side of the tool holder movable plate 53 is in contact with the tool holder frame plate 52, and the other side of the tool holder movable plate 53 moves up and down through the gear and rack assembly 54. The movable groove is adapted to the tool holder frame plate 52 and the tool holder movable plate 53.

[0087] The lower cutting edge 56 is located at the bottom of the tool holder frame plate 52, and the cutting edge of the lower cutting edge 56 faces upward.

[0088] Upper cutting edge 55, the upper cutting edge 55 is located at the bottom of the movable plate 53 of the tool holder, and the cutting edge of the upper cutting edge 55 faces downward;

[0089] The cutting edges of the upper blade 55 and the lower blade 56 are both V-shaped, and the upper blade 55 and the lower blade 56 are positioned correspondingly, which allows the wire to be positioned at the bottom of the V-shape.

[0090] The shearing motor 57 is also located on the front side of the upright plate 1. The output shaft of the shearing motor 57 passes through the upright plate 1 to the back side of the upright plate 1 and is connected to the gear and rack assembly 54 by belt drive or chain drive. In this embodiment, belt drive is preferred, and the transmission belt of the belt drive is a synchronous toothed belt. The transmission wheel is adapted to the synchronous toothed belt, resulting in higher motion accuracy.

[0091] The shearing motor 57 rotates in both directions, driving the gear and rack assembly 54 to move up and down, thus achieving the shearing function. It then works in conjunction with the stepper assembly 4 to complete the peeling function.

[0092] The peeling function is briefly explained below:

[0093] In the initial stage, the wire is fed forward by stepping, passing over the stripping and shearing assembly by a length L. By controlling the rotation amplitude of the shearing motor 57, the upper blade 55 descends. The distance between the upper blade 55 and the lower blade 56 is matched with the wire core diameter, thus leaving a cut on the wire insulation layer. At this time, the upper blade 55 remains stationary, and the stepping wheel group 4 retracts, with the wire retraction length being L, stripping the outermost insulation layer of the wire. Then, the upper blade 55 rises, and the stepping wheel group 4 advances, with the wire advancing by a length L1. L1 is the length of the wire used for the ignition needle; then the upper blade 55 is lowered so that the distance between the upper blade 55 and the lower blade 56 matches the wire core diameter again. At this time, the stepping wheel group 4 retracts by 1 / 2L, which allows the insulation layer of the wire to move forward by 1 / 2L. Then the upper blade 55 moves up, and the stepping wheel group 4 controls the wire to move forward by 1 / 2L. Finally, the upper blade 55 moves down to cooperate with the lower blade 56 to cut the wire. A wire with a total length of L1 is obtained, and 1 / 2L of wire core is exposed at both ends of the wire.

[0094] Based on the above technical solution, the output shaft of the shear motor 57 is also equipped with a position sensor or angle encoder 571.

[0095] The rotation range of the shearing motor 57 is controlled by the position sensor or angle encoder 571, thereby controlling the stroke of the blade holder movable plate 53, that is, controlling the displacement accuracy of the upper blade 55.

[0096] Based on the above technical solution, the front and rear ends of the stepper wheel assembly 4 are also provided with cable protection tubes 7.

[0097] The conduit 7 serves to protect the wires.

[0098] Based on the above technical solution, a wire feeding guide component 6 is also provided after the wire outlet end of the stripping and shearing integrated component 5. The wire feeding guide component includes a guide block 61, and a tapered hole is opened on the side of the guide block 61 facing the stripping and shearing integrated component 5.

[0099] The cut wire end is in a free state and may be deflected; in order to allow the wire to smoothly enter the subsequent wire feeding process, the tapered hole of the guide block 61 has the function of guiding the wire end to enter it accurately.

[0100] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
