DETAILED DESCRIPTION

[0032] The technical solutions of the present application will be described clearly and completely below in conjunction with the embodiments. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0033] Embodiment one: please refer to Figure 1 Figure 4 As shown in the figure, the multi-wire bundle terminal crimping machine based on synchronous peeling includes a bottom frame 1 and a pretreatment frame 2, the pretreatment frame 2 is fixedly installed at the center inside the bottom frame 1, and the center of the frame body on both sides of the pretreatment frame 2 is provided with a threading groove, the inside of the pretreatment frame 2 is provided with a dynamic processing mechanism 3, and the top of the frame body on both sides of the bottom frame 1 is provided with a rectangular clamping groove, and the inside of the two clamping grooves is respectively provided with a rotating roller and a crimping mechanism 4;

[0034] And a plurality of groups of wire feeding cylinders are fixedly sleeved outside the rotating roller, and the wire bundle is sequentially conveyed to the inside of the pretreatment frame 2 and the crimping mechanism 4 through the plurality of groups of wire feeding cylinders, the wire bundle entering the inside of the pretreatment frame 2 is sequentially subjected to skinning, peeling, and impurity removal treatment, so as to force the wire core end to be exposed, and then the crimping mechanism 4 is used to assemble and crimp the wire core and the terminal;

[0035] Among them, the dynamic processing mechanism 3 includes a sliding plate 31 slidingly connected to the inner wall of one side of the pretreatment frame 2 and located at the upper end of the threading groove, and a sliding strip fixedly installed on one side of the sliding plate 31 is in sliding fit with a sliding groove provided at the inner side of the pretreatment frame 2, a cylinder one 32 is provided at the front end of the sliding plate 31 through a push rod, and the cylinder one 32 is arranged at the inner side wall of the pretreatment frame 2 through a machine base, and a plurality of groups of sliding shafts 33 are arranged at the side away from the sliding strip of the sliding plate 31 at equal distances;

[0036] A plurality of pairs of material clamping assemblies are hinged to the inner side wall of the pretreatment frame 2 and located at the lower end of the sliding plate 31, each pair of material clamping assemblies is composed of two symmetrically distributed clamping frames 34, the clamping frame 34 is hinged to the inner side wall of the pretreatment frame 2, and a vertical frame 35 is fixedly installed on the top of one of the clamping frames 34, and the vertical frame 35 is sleeved outside the corresponding sliding shaft 33, and each of the two adjacent clamping frames 34 is provided with a blade 36 at the opposite surface and flush with the threading groove;

[0037] The bottoms of the plurality of groups of clamping frames 34 extend to below the threading groove and are jointly sleeved with two groups of limiting sleeve frames 37, sliding blocks fixedly installed at the rear ends of the two groups of limiting sleeve frames 37 are in sliding fit with vertical grooves arranged at the front and rear ends of the inner side wall of the pretreatment frame 2, one end of the upper and lower two groups of limiting sleeve frames 37 is respectively screw-penetrated with a screw guide rod 38 with opposite screw threads, the upper and lower two groups of screw guide rods 38 are fixedly connected through a connecting rod, and one end of one of the screw guide rods 38 away from the connecting rod is provided with a motor one 39;

[0038] ​Wire harness cutting stage: a plurality of groups of wire harnesses first pass through the inside of the group of threading slots on one side and are located between the upper and lower groups of limiting sleeve frames 37, and at the same time, the front and rear ends of each group of wire harnesses are limited by the clamping frames 34, and then the motor one 39 is started to drive the two groups of spiral guide rods 38 to rotate in the same direction. Because the external threads of the upper and lower groups of spiral guide rods 38 are arranged in opposite directions;

[0039] Therefore, the two groups of limiting sleeve frames 37 matched with the two groups of spiral guide rods 38 will move closer or farther away from each other. When the two groups of limiting sleeve frames 37 move closer to each other, the upper and lower ends of the wire harness are adaptively limited. At the same time, the cylinder one 32 is started to move the sliding plate 31 by pushing the push rod, and the sliding plate 31 pulls the plurality of groups of sliding shafts 33 to move. The sliding shafts 33 press against the inner wall of the vertical frame 35, forcing the clamping frame 34 at the bottom of the vertical frame 35 to deflect and pushing the wire harness to move closer to the other clamping frame 34. At this time, the two groups of blades 36 corresponding in front and back are inserted into the outer sheath layer of the wire harness, and as the wire harness moves, the linear cutting of the front and rear ends of the outer sheath of the wire harness is realized.

[0040] It is worth noting that each group of limiting sleeve frames 37 is provided with a wedge-shaped frame 310 on one side, and the front and rear ends of the wedge-shaped frame 310 are respectively connected with the corresponding limiting sleeve frame 37. The upper and lower groups of wedge-shaped frames 310 are mirror images and are arranged at the upper and lower ends of the threading slots on the other side of the pretreatment frame 2. The wire harness is moved to the other group of threading slots after being cut by the dividing line.

[0041] During this period, the wire harness also passes between the upper and lower groups of adjacent wedge-shaped frames 310. The positions of the upper and lower groups of wedge-shaped frames 310 change with the positions of the limiting sleeve frames 37, and the upper and lower groups of wedge-shaped frames 310 match the diameter of the peeled wire core. Therefore, when the wire harness passes through the wedge-shaped frame 310, the outer sheath is separated from the wire core. After the peeling stage, the outer sheath at the end of the wire harness is completely removed, and the internal wire core is exposed.

[0042] Please refer to Figure 5 - Figure 7 As shown, the dynamic processing mechanism 3 further includes a plurality of groups of tooth ring frames 311 rotatably arranged on the outer wall of the pretreatment frame 2 on one side. Each group of tooth ring frames 311 has four groups of edges on the outside, each of which is sleeved with a double-shaft rotating cylinder 312, and one end of the double-shaft rotating cylinder 312 is rotatably connected with the side wall of the pretreatment frame 2. Adjacent two groups of tooth ring frames 311 are jointly meshed with auxiliary rotating teeth rollers 313.

[0043] One end of the auxiliary gear roller 313 is provided with a motor 314, and the vertical clamping plate 315 is vertically installed at the center of the inner part of the gear ring frame 311. The opposite center of the two vertical clamping plates 315 is fixedly installed with a horizontal clamping strip 316, and the opposite side of the two horizontal clamping strips 316 is provided with a rough surface. The center of the two horizontal clamping strips 316 away from each other is fixedly installed with a plug rod 317, and one end of the plug rod 317 penetrates through the vertical clamping plate 315. The plug rod 317 is externally wound with a pressure spring group ring 318.

[0044] The impurity removal stage: the peeled core is sequentially penetrated into the inner part of the corresponding gear ring frame 311, and is adaptively clamped between the adjacent two horizontal clamping strips 316. At this time, the motor 314 is started to drive the auxiliary gear roller 313 to rotate. The auxiliary gear roller 313 drives the adjacent gear ring frame 311 to rotate. The double-shaft rotating drum 312 is rotatably connected to the side wall of the pretreatment frame 2.

[0045] The stability of the gear ring frame 311 is ensured during rotation. The vertical clamping plate 315 and the horizontal clamping strip 316 in the inner part are rotated by the gear ring frame 311. Since the core is adaptively clamped between the adjacent two horizontal clamping strips 316, the impurities adhered to the outer wall of the core can be removed by friction during the rotation of the horizontal clamping strip 316. The cleanliness of the core surface is improved to prevent the influence of colloid or impurities on the butt joint effect of the terminal.

[0046] Meanwhile, one end of the plug rod 317 penetrates through the vertical clamping plate 315, and the plug rod 317 is externally wound with a pressure spring group ring 318. The pressure spring group ring 318 applies an outward pushing force to the horizontal clamping strip 316, so that the horizontal clamping strip 316 is always in contact with the outer wall of the core, and the impurity removal effect is ensured.

[0047] The skinning, peeling and impurity removal of the wire harness are realized by the dynamic processing mechanism 3. The operation is convenient and the degree of automation is high, which greatly improves the production efficiency.

[0048] Example two: please refer to Figure 2 、 Figure 7 and Figure 8 The crimping mechanism 4 includes a cylinder 41 arranged at the inner wall of the top of the clamping groove away from the end of the rotating roller, and the cylinder 41 is connected with a positioning strip 42 through a push rod. The bottom of the positioning strip 42 is provided with a plurality of pressure plates 421 at equal distances. The center of the pressure plate 421 is provided with a hot pressing column 43, and the bottom surface of the pressure plate 421 is provided with a wedge-shaped resistance strip 44 at four corner positions. The four wedge-shaped resistance strips 44 correspond to the front and rear ends of the inclined surfaces of the two resistance frames 47, respectively, for resisting the inclined surface of the top of the resistance frame 47 without being blocked.

[0049] The crimping mechanism 4 further comprises a slide rod 45 fixedly installed inside the clamping groove and located at the lower end of the pressing plate 421, and the slide rod 45 is externally and equidistantly fixedly sleeved with a plurality of sets of positioning blocks 46, and each set of positioning block 46 is slidably sleeved with a resisting frame 47 at both ends, and the top surfaces of the two adjacent resisting frames 47 are oppositely chamfered;

[0050] The bottom of the end of the resisting frame 47 away from the positioning block 46 is slidably sleeved outside the slide rod 45, and the outside of the slide rod 45 and the adjacent resisting frame 47 are respectively wound with a buffer spring group ring 48, and the outside of the slide rod 45 and between the two adjacent buffer spring group rings 48 are jointly provided with a partition plate, and the four sets of wedge-shaped resisting strips 44 are respectively pressed against the front and rear ends of the inclined surfaces of the two sets of resisting frames 47, so that the two sets of resisting frames 47 symmetrically left and right are forced to approach each other and press against the terminal housing;

[0051] Specifically, the following process is included: after the pretreatment is completed, the wire core end is completely treated clean, then a plurality of sets of terminals are placed on the surface of the positioning block 46, and the wire core end penetrates through the corresponding terminal inner groove, at this time, the cylinder two 41 is started to push the positioning long strip 42 and a plurality of sets of pressing plates 421 downward through the push rod;

[0052] Among them, the bottom inclined surface of the plurality of sets of wedge-shaped resisting strips 44 is respectively pressed against the bottom inclined surface of the corresponding resisting frame 47, so that the resisting frames 47 at both ends of the pressing plate 421 are forced to approach each other and jointly resist the terminal side wall, the buffer spring group ring 48 is stretched, so as to avoid the terminal from shaking during hot pressing, and improve the stability of the crimping;

[0053] Then, the hot pressing column 43 performs hot pressing assembly treatment on the terminal and the wire core; and after the hot pressing is completed, the cylinder two 41 is reset, the wedge-shaped resisting strip 44 is lifted to lose the pressing on the resisting frame 47, and the terminal and the wire core after crimping are taken out through the elastic reset of the buffer spring group ring 48;

[0054] It is worth noting that the hot pressing column 43 is externally provided with a heating layer, and the heating layer is electrically connected with an external power supply, so as to heat the hot pressing column 43 through the heating layer, so as to ensure that the hot pressing column 43 performs hot pressing assembly treatment on the terminal and the wire core, and improves the stability of the crimping;

[0055] Then, the crimping mechanism 4 realizes the automatic assembly and crimping treatment of the wire core and the terminal, the crimping is stable and convenient to operate, and the production efficiency is greatly improved.

[0056] Working principle: when the present application is used, first, a plurality of wire harnesses are respectively inserted through the wire insertion grooves on both sides of the pretreatment frame 2 and located between the upper and lower sets of limiting sleeve frames 37, at this time, the front and rear ends of each wire harness are limited by the corresponding clamping frames 34, the motor one 39 is started to drive the two sets of spiral guide rods 38 to rotate in the same direction, the two sets of limiting sleeve frames 37 approach each other, until the upper and lower ends of the wire harness are tightly limited;

[0057] At the same time, the starting cylinder 32 pushes the slide plate 31 along the slide groove inside the pretreatment frame 2 through the push rod, and drags several groups of slide shafts 33 to move, the moving end of the slide shaft 33 abuts against the inner wall of the vertical frame 35, forcing the clamping frame 34 at the bottom of the vertical frame 35 to deflect, and pushing the wire harness to approach the other clamping frame 34. In this process, the two groups of blades 36 corresponding in front and back respectively insert into the outer sheath layer of the wire harness, and with the continuous movement of the wire harness, the two groups of blades 36 achieve linear cutting of the front and back ends of the outer sheath of the wire harness.

[0058] After the cutting is completed, the wire harness continues to move to the other group of threading grooves, and passes between the upper and lower two groups of adjacent wedge-shaped frames 310. Since the position of the wedge-shaped frame 310 changes with the change of the position of the limiting sleeve frame 37, and the wedge-shaped frame 310 matches the diameter of the peeled wire core, when the wire harness passes through the wedge-shaped frame 310, the outer sheath and the wire core are smoothly separated, completing the peeling stage. The wire core after peeling exposes the internal wire core, preparing for the impurity removal processing stage.

[0059] In the impurity removal processing, the wire core after peeling will sequentially penetrate the inside of the corresponding tooth ring frame 311, and be adaptively clamped between the adjacent two groups of horizontal clamping strips 316. At this time, the auxiliary rotating tooth roller 313 and the adjacent tooth ring frame 311 are driven to rotate by the starting motor 314, and the vertical clamping plate 315 and the horizontal clamping strip 316 rotate with the tooth ring frame 311. Since the wire core is clamped between the horizontal clamping strips 316, as the horizontal clamping strips 316 rotate, the impurities attached to the outer wall of the wire core are removed by friction, improving the cleanliness of the surface of the wire core.

[0060] After completing the impurity removal processing, the wire core enters the crimping mechanism 4 for assembly and crimping. At this time, a plurality of terminals are placed on the surface of the positioning block 46, and the end of the wire core penetrates the corresponding inner groove of the terminal. The positioning long strip 42 and the plurality of pressure plates 421 are pushed down by the push rod of the starting cylinder 42, the wedge-shaped abutting strip 44 at the bottom of the pressure plate 421 abuts against the bottom inclined surface of the corresponding abutting frame 47, forcing the abutting frames 47 to approach each other and abutting against the side wall of the terminal for limiting; at the same time, the hot pressing column 43 performs hot pressing assembly processing on the terminal and the wire core. After hot pressing is completed, the cylinder 42 is reset, the wedge-shaped abutting strip 44 is lifted and loses the abutting pressure on the abutting frame 47, and the abutting frame 47 is reset by the elastic force of the buffer spring group ring 48, so as to facilitate taking out the crimped terminal and wire core.

[0061] Through the cooperative work of the dynamic processing mechanism 3 and the crimping mechanism 4, the wire harness is peeled, peeled, impurity removed, and the wire core and the terminal are automatically assembled and crimped, greatly improving the production efficiency.
