Detailed Description
In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed in a specific orientation, and be operated, and thus, should not be construed as limiting the present invention.
The contents of the present invention will be further described in detail with reference to the specific embodiments, and fig. 1 and fig. 2 respectively show the three-dimensional schematic view of the connector terminal cutting machine and the partial enlarged view of the connector terminal cutting machine of the present invention, it can be seen that the connector terminal cutting machine mainly comprises a machine table 1, an unreeling feeding mechanism 2, a material poking mechanism 3, a cutting mechanism 4, a material box 5, a material box lifting mechanism 6, and other parts. Wherein, unreel feeding mechanism 2, dial material mechanism 3, cut mechanism 4 and arrange according to the preface along the flow direction in terminal material area, and all be fixed in on above-mentioned board 1. The material box 5 is used for collecting terminal cutting finished products formed by cutting the terminal material belt. It is important to note here that the magazine lifting mechanism 6 is disposed immediately downstream of the cutting mechanism 4 for driving the magazine 5 to perform intermittent displacement motion in the up-down direction. The material box 5 is internally provided with a containing cavity which is matched with the shape of the terminal cutting finished product and is used for stacking the terminal cutting finished product. Assuming that the thickness of the terminal cutting finished product is t, when the cutting mechanism 4 finishes one cutting action on the terminal material belt and falls and fixes in the material box 5, the material box lifting mechanism 6 performs one downward moving action, and the displacement distance is t, so as to prepare for the subsequent blanking action of cutting the terminal cutting finished product. Through adopting above-mentioned technical scheme to set up, guaranteed effectively that the terminal cuts the regularity that finished product spare was place in magazine 5. Therefore, on one hand, in the actual material taking operation process, workers hold the terminals layer by layer and sequentially to cut finished products, so that the difficulty of operation of the workers is reduced, and higher material taking efficiency is obtained; on the other hand, the phenomenon that scraping occurs between the terminal cutting finished product piece and the terminal cutting finished product piece is avoided in the process of transferring or taking materials from the material box 5, and then the stability of signal and current transmission of the formed connector is ensured.
As is known, the above-mentioned magazine lifting mechanism 6 may adopt various design structures to complete the intermittent jacking action of the magazine 5, however, a preferred structure with a simple design, convenient implementation and convenient subsequent maintenance is recommended here, which is specifically as follows: the magazine lifting mechanism 6 is mainly composed of a fixed base 61, a linear driving portion 62, and a first bracket 63. The magazine 5 is detachably fixed to the fixing base 61 and moves in a synchronized displacement along with the fixing base 61. The first support 63 is fixed to the machine 1. The linear driving part 62 is connected between the fixed base 61 and the first bracket 63 to drive the fixed base 61 to perform a directional displacement motion (as shown in fig. 10).
Generally, the linear driving part 62 is preferably composed of a first rotating electric machine 621, a driving pulley 622, an endless belt 623, a driven pulley 624, and a clamping assembly 625. The driving pulley 622 and the driven pulley 624 are supported by the first carrier 63 described above and are freely rotatable about their respective central axes. The endless belt 623 is simultaneously fitted over the driving pulley 622 and the driven pulley 624. The driving pulley 622 is driven by a first rotating electric machine 621 to rotate an endless belt 623 endlessly. The clamping assembly 625 performs a clamping action on the endless belt 623, follows the synchronous displacement movement of the endless belt 623, and is connected and fixed with the fixed seat 61 so as to perform a directional displacement movement of the fixed seat 61 relative to the first bracket 63 in an up-and-down direction (as shown in fig. 11 and 12). The linear driving unit 62 has a simple structural design and a high response speed. More importantly, the first rotary motor 621 has fast start, stop and forward and reverse rotation features to facilitate its intermittent motion drive and control of the cartridge 5.
As a further optimization of the above technical solution, the magazine lifting mechanism 6 may further be additionally provided with a first sliding rail slider assembly 64 according to actual conditions. The first slide rail slider assembly 64 is composed of a first slide rail and a first slider, wherein the first slide rail is vertically disposed in the up-down direction and detachably fixed to the first bracket 63. And the first sliding block matched with the first sliding rail is detachably fixed on the fixed seat 61 (as shown in fig. 10). The existence of the first sliding rail slider assembly 64 effectively improves the direction accuracy of the displacement process of the fixed seat 61 along the up-down direction. Thus, the aligning precision of the material box 5 and the cutting mechanism 4 is ensured, and the terminal cutting finished product is accurately blanked in the material box.
Furthermore, in view of ensuring the operation safety of the connector terminal cutting machine and the high alignment accuracy of the magazine 5 and the cutting mechanism 4, the magazine lifting mechanism 6 may be provided with an automatic stopper 65 (as shown in fig. 10). The auto-limiting portion 65 includes a sensor chip 651, an upper groove type lead switch 652, a middle groove type lead switch 653, and a lower groove type lead switch 654. The sensing piece 651 is fixed to the fixing base 61 and moves synchronously with the fixing base 61. The upper groove type wire-type photoelectric switch 652, the middle groove type wire-type photoelectric switch 653, and the lower groove type wire-type photoelectric switch 654 are fixed to the first bracket 63, and are sequentially arranged and disposed along the top-to-bottom direction to respectively define an upper limit position, an initial working position, and a lower limit position of the fixing base 61 (as shown in fig. 13).
It should be noted that after the connector terminal cutting machine is operated for a certain period of time, the operation accuracy is inevitably greatly reduced, and the alignment accuracy between the magazine 5 and the cutting mechanism 4 is greatly reduced. In order to solve the technical problem, the magazine lifting mechanism 6 may further include a first short slide rail, a second short slide rail, and a third short slide rail according to actual conditions, and correspondingly, a sliding groove adapted to the first short slide rail, the second short slide rail, and the third short slide rail is disposed on the right side wall of the first bracket 63. The upper groove type wire photoelectric switch 652, the middle groove type wire photoelectric switch 653, and the lower groove type wire photoelectric switch 654 are fixed to the first short rail, the second short rail, and the third short rail in a one-to-one correspondence, and perform synchronous displacement movement (as shown in fig. 13) in a following manner. In this way, when the relative height positions of the upper groove type wire photoelectric switch 652, the middle groove type wire photoelectric switch 653, and the lower groove type wire photoelectric switch 654 need to be adjusted, the first short slide rail, the second short slide rail, and the third short slide rail are correspondingly dragged along the up-down direction.
As shown in fig. 8, the magazine 5 is mainly composed of a bottom plate 51, a front plate 52, a rear plate 53, and a right side plate 54. The bottom plate 51, the rear plate 53 and the right side plate 54 are fixedly connected to each other. While the front plate 52 stands up, bearing against the upper plane of the bottom plate 51 and is coupled to the right side plate 54 by means of screws 55. A series of screw holes for screwing the screws 55 are formed in the right side wall of the front plate 52 in an up-down direction, and correspondingly, a series of kidney-shaped through holes (as shown in fig. 8 and 9) extending in the front-back direction for passing the screws 55 are formed in the right side plate 54. By adopting the technical scheme, on one hand, the size of the accommodating cavity is convenient to adjust according to the actual size of the terminal cutting finished product, so that the consistency of the relative position of the terminal cutting finished product in stacking is ensured; on the other hand, when the model in terminal material area changed, be convenient for adjust the width value that holds the chamber according to its actual width to the application scope of magazine 5 has been enlarged effectively.
The adjustment of the magazine 5 is specifically as follows: firstly, the screw 55 needs to be loosened, then the relative position of the front plate 52 is adjusted along the front-back direction until the enclosed width of the accommodating cavity is matched with the width of the terminal cutting finished piece, and finally the screw 55 is locked.
As a further refinement of the structure of the connector terminal cutting machine, the kick-out mechanism 3 is preferably composed of several parts, such as a first mounting board 31, a kick-out wheel 32, a second rotating motor 33, and a follower wheel 34. The first mounting substrate 31 is fixed to the machine 1. The kick-off wheel 32 and the follower wheel 34 are disposed to face each other in the vertical direction, and are supported by the first mounting board 31. An annular relief groove 341 is cut around the periphery of the follower wheel 34. Just corresponding to the annular avoiding groove 341, a series of material shifting teeth 321 for shifting the terminal material belt to move forward are uniformly distributed around the periphery of the material shifting wheel 32. The kick-off wheel 32 is subjected to a circumferential rotary motion about its central axis by a second rotary motor 33 (as shown in figure 5). The material poking mechanism 3 is simple in design structure, convenient to implement and convenient to maintain. In addition, more importantly, accurate feeding of the terminal material belt is convenient to achieve, and slipping which often occurs in the process of conventional feeding (most of the conventional feeding is of a friction wheel structure, and feeding of the terminal material belt is completed by means of friction force generated by pretightening force) is avoided.
As shown in fig. 18, a series of tooling holes are linearly arrayed along the length of the terminal strip. And the distance between the process holes is set as a; assuming that the setting wheel 32 is completely flattened along its circumference, and the distance between the setting teeth 321 is set as b, a is b.
The operating principle of the material poking mechanism 3 is as follows: the material-poking wheel 32 is driven by the second rotating motor 33 to rotate, and meanwhile, one of the material-poking teeth 321 arranged on the periphery thereof is inserted into a process hole (as shown in fig. 18) formed in the terminal material strip and gradually separated from the process hole in the rotation process of the material-poking wheel 32, so that one-time feeding of the terminal material strip is completed; subsequently, the material-shifting wheel 32 continues to rotate, so that the other material-shifting tooth 321 on the material-shifting wheel repeats the above actions to complete the secondary feeding operation; the above-mentioned action process is repeated for a plurality of times in the rotation motion of the kick-off wheel 32, and finally the continuous feeding operation of the terminal material belt is completed.
It is known that when the terminal material belt is thin, the terminal material belt is very easy to warp in the flowing process, so that the terminal material belt cannot smoothly and automatically enter the material poking mechanism 3, and further, no manual assistance is needed in the feeding process. In view of this, when the thickness of the terminal material tape is less than 0.2mm, a leveling mechanism 7 (as shown in fig. 14) needs to be added just upstream of the material poking mechanism 3 to continuously and real-timely flatten the terminal material tape to ensure that the terminal material tape has a better flatness.
As a further refinement of the structure of the leveling mechanism 7, the leveling mechanism includes a second mounting board 71, a cover plate 72, an adjusting block 73, an under spring 74, a leveling roller 75, and an adjusting bolt 76. The adjusting block 73, the lower spring element 74, the leveling roller 75 and the adjusting bolt 76 are provided in a plurality of numbers and are consistent. Receiving grooves extend downward from the top wall of the second mounting substrate 71 along the flowing direction of the terminal tape. The adjusting blocks 73 are arranged in order and are built in the accommodating groove. The lower spring members 74 are also disposed in the receiving grooves and are elastically pressed against the lower surface of the adjusting block 73 and the bottom wall of the receiving grooves in a one-to-one correspondence. The cover plate 72 is detachably fastened and fixed to the top wall of the second mounting substrate 71. The adjusting screw 76 passes through the cover plate 72 and its free end abuts against the upper plane of the adjusting block 73. The leveling rollers 75 are fixed to the adjusting blocks 73 in a one-to-one correspondence, and perform a synchronous displacement motion following the adjusting blocks 73. The leveling rollers 75 are offset from each other in the vertical direction to form a shaping channel for the terminal strip to flow through (see fig. 14, 15, and 16). It should be noted that, due to the presence of the under-spring element 74, the terminal material strip is always kept in an elastic compression state, so that the phenomenon of surface pressure loss caused by rigid extrusion is avoided, and the adjustment of the width value of the shaping channel by rotating the adjusting bolt 76 is facilitated, thereby expanding the range of types of the terminal material strip processed by the flattening mechanism 7.
It is known that during the process of leveling the terminal strip by means of the leveling mechanism 7, the terminal strip is very prone to "off-tracking" when the terminal strip flows in the above-mentioned overall channel due to the influence of the mounting accuracy of the leveling roller 75 itself and the surface wear factor thereof. In view of this, as a further optimization of the structure of the connector terminal cutting machine, a guide mechanism 8 is additionally provided. The pilot mechanism 8 is disposed immediately upstream of the leveling mechanism 7, and is also supported by the above-described second mounting substrate 71 (as shown in fig. 14).
The guide mechanism 8 further includes a cross beam 81, a sliding block 82, a guide wheel 83, an adjusting screw 84, and a horizontal guide plate 85. A sliding groove is formed on the left side of the accommodating groove and extends backwards from the front side wall of the second mounting substrate 71. A series of material guiding teeth 831 which move forward along with the terminal material strips are uniformly distributed around the periphery of the material guiding wheel 83. The guide wheel 83 is connected with the sliding block 82 into a whole, is arranged in the sliding groove in the whole body, and can perform directional displacement motion along the sliding groove. The guide wheel 83 is free to rotate circumferentially about its own central axis. The horizontal guide plate 85 is also supported by the second mounting base plate 71 and is disposed directly below the guide wheel 73. Just corresponding to the material guiding teeth 831, a strip-shaped avoiding groove 851 consistent with the flowing direction of the terminal material belt extends downwards from the upper plane of the flat material guiding plate 85. The beam 81 and the second mounting board 71 are detachably fixed, and are covered directly above the sliding groove. The adjusting screw 84 is screwed to and passes through the cross beam 81, and the lower end thereof is fixed to the slide block 72. When the adjusting screw 84 is rotated, the sliding block 82 is dragged to move along with the guide wheel 83 to move toward and away from the flat guide plate 85 (as shown in fig. 14). Through adopting above-mentioned technical scheme to set up to improved effectively that the terminal material area has enough high counterpoint precision for above-mentioned levelling mechanism 7 in the twinkling of an eye of pan feeding, and then ensured that the terminal material area accurately passes through above-mentioned plastic passageway infallibly, stopped the emergence of "off tracking phenomenon".
Furthermore, in order to ensure a simple design structure of the cutting mechanism 4 and facilitate manufacturing and forming while ensuring sufficient shearing force, the cutting mechanism 4 is preferably composed of the second bracket 41, the lower cutting blade assembly 42, the upper cutting blade assembly 43, the force transmission lever 44, the linear motion element 45, the second sliding rail slider assembly 46, and the transition plate 47. The upper cutting blade unit 43 is disposed right in front of the second holder 41, and is positioned opposite to the lower cutting blade unit 43. The lower cutting blade assembly 43 is supported by the second bracket 41 and includes an upper cutting blade 431 and a mounting seat 432. The upper cutting blade 431 is detachably fixed to the mounting seat 432 by means of a fastener. The second slide rail slider assembly 46 is comprised of a second slide rail and a second slider. The transition plate 47 is connected to both the second slide rail and the mounting seat 432. And a second slider adapted to the second slide rail is detachably fixed to the front side wall of the second bracket 41. A mounting groove extends downward from the top of the second bracket 41. The linear motion element 45 is fixed to the machine table 1 and is disposed right behind the second support 41. The force transmission lever 44 is composed of a forward extending section 441, an assembling section 442 and a rear section 443 in this order. The assembly section 443 is built in and hinged to the mounting groove. The power output end of the linear motion element 45 is hinged to the rear section 443, and the force transmission lever 44 is freely swung around the hinge center under the action of the pushing and pulling force to drag the upper cutting blade assembly 43 to move toward/away from the lower cutting blade assembly 42 (see fig. 6 and 7). It should be emphasized here that the presence of the force transmission lever 44 can effectively reduce the requirement of the cutting mechanism 4 for outputting the driving force to the linear motion element 45 on the premise of a certain shearing force, thereby facilitating the miniaturization and model selection of the linear motion element 45.
As a further optimization of the above technical solution, the cutting mechanism 4 may be additionally provided with a roller 48 according to actual conditions. The roller 48 is detachably fixed to the front extension 441, and correspondingly, a force transmission groove 4321 is formed on the mounting seat 432. The roller 48 is embedded in the force transfer groove 4321. When the force transmission lever 44 is swung, the roller 48 rolls freely along the above-mentioned force transmission groove 4321 (as shown in fig. 6 and 7). Through adopting above-mentioned technical scheme to set up and produce and have following beneficial effect: the force transmission process of the cutting mechanism 4 is smoother, and the force transmission efficiency is higher; in addition, the force transmission lever 44 transmits the force of the upper cutting knife assembly 43 by means of the roller 48, so that the phenomenon of over-speed abrasion caused by sliding contact in the force transmission process is effectively avoided, the service life of the cutting mechanism 4 is effectively prolonged, and the later maintenance frequency and cost are reduced.
The unwinding and feeding mechanism 2 is preferably composed of a third frame 21, a feeding turntable 22, a winding paper turntable 23, a third rotating motor 24, and a web guide 25. The third support 21 is fixed to the machine 1. The supply reel 22 and the winding paper reel 23 are supported by the third support frame 21. The feeding rotary table 22 has no driving power input all the time, and when the material poking mechanism 3 pokes the terminal material belt to move forwards, the terminal material belt can rotate freely in the circumferential direction around the central axis of the terminal material belt. A third rotary motor 24 is disposed right behind the roll paper turntable 23 to drive the roll paper turntable 23 to perform a circumferential free rotary motion about its central axis (as shown in fig. 4). The tape guide 25 is placed right below the feeding turntable 22, and a trough 2511 (shown in fig. 3) for carrying the terminal tape after unwinding is completed is opened thereon. Under the basic premise of ensuring stable feeding of the terminal material belt, the feeding rotary table 22 is always kept in a free rotation state (no power input is needed in the whole process), so that the design structure of the feeding rotary table 22 is effectively simplified, and the phenomenon of material pulling caused by driving asynchronism is avoided.
As is known, the feeding of the terminal material tape is mainly driven by the material-ejecting force of the material-ejecting mechanism 3, and the feeding turntable 22 is kept in a free rotation state. When the kick-out device 3 is suddenly stopped, the feed operation can be stopped instantly, and the feed turntable 22 is still kept in a rotating state under the action of inertia force, so that the terminal material belt is supplied excessively and stacked in the material belt guide 25, and furthermore, the terminal material belt exceeds the material belt guide 25 to cause the phenomenon of 'lap and droop'; when the kick-off mechanism 3 is restarted, the edge of the material belt guiding member 25 is very easy to cut or scrape the terminal material belt. In view of this, the web guide 25 is preferably a split structure, and includes a guide body 251 and an arc-shaped guide plate 252. The trough 2511 is opened to the guide body 251. The arc-shaped guide plate 252 is disposed at the left side of the guide body 251 and is butted against the guide body 251. The arc-shaped guide plate 252 is positioned opposite to the trough 2511 (as shown in fig. 17).
The working principle of the connector terminal cutting machine is as follows: the containing cavity arranged in the material box 5 is matched with the shape of the terminal cutting finished product part so as to ensure the stacking stability of the terminal cutting finished product part after being placed. The material box 5 is supported and clamped by the material box lifting mechanism 6 and carries out directional displacement motion along the up-down direction. Under the action of the material shifting mechanism 3, the material feeding turntable 22 continuously finishes the material discharging operation on the terminal material belt, and meanwhile, the paper winding turntable 23 finishes the collection of the protective film or paper adhered on the terminal material belt; subsequently, the cutting mechanism 4 cuts the terminal material strip according to the terminal length required by the electrical connector. When the cutting mechanism finishes cutting the terminal material belt once and falls into the material box 5, the material box 5 is driven by the material box lifting mechanism 6 to move downwards for a small distance, and the downwards moving distance is consistent with the thickness of the terminal material belt every time, so that the terminal cutting finished product is sequentially stacked in the material box 5, the phenomenon that the terminal cutting finished product falls off layer by layer due to the fact that the material box 5 shakes in the subsequent transfer process is prevented, and the regularity of placing the terminal cutting finished product is ensured.
