Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of wiring harness processing, in particular to a multi-wiring harness terminal crimping and assembling integrated machine. BACKGROUND

[0002] The wiring harness terminal crimping and assembling shell integrated machine is an automatic equipment for crimping the wiring harness and the terminal and assembling them into the shell. The process steps of the wiring harness terminal crimping and assembling shell include: the wiring harness feeding assembly feeds the wiring harness on the control arm to extend to one end of the control block on the control arm, the control arm controls the movement of the extended end of the wiring harness to the stripping mechanism to expose the wire after stripping, the terminal is fed to the crimping mechanism on the terminal feeding assembly, the control arm controls the wire on the wiring harness to enter the crimping mechanism to complete the crimping action with the terminal, the shell is fed to the shell assembling mechanism on the shell feeding assembly, the control arm controls the wiring harness terminal to be inserted into the shell on the shell assembling mechanism, and finally the clamping arm clamps and moves out the end of the wiring harness with the shell, the wiring harness feeding assembly continuously controls the wiring harness feeding, the cutting structure cuts the other end of the wiring harness away from the shell, and the stripping-crimping-shell inserting action is repeated.

[0003] Referring to a Chinese patent with application number 202311791406.1, a wiring harness terminal crimping and assembling shell integrated machine is disclosed. The guide sleeve is used to resist between the shell and the wiring harness before the wiring harness terminal is inserted into the shell hole, so that the wiring harness terminal can be driven along the guide sleeve and smoothly inserted into the shell hole. This avoids the wiring harness terminal and the wiring harness not being on the same straight line, which prevents the insertion process from being completed, reduces the defective rate of the wiring harness terminal crimping and assembling shell, and reduces the waste of raw materials compared with other equipment. However, when the above-mentioned wiring harness terminal crimping and assembling shell integrated machine is used for crimping multiple wiring harness terminals, it cannot independently position multiple wiring harnesses, which may cause deviation between the terminal crimping end and the terminal crimping end when the device crimps multiple wiring harness terminals, resulting in the terminal not being tightly sleeved around the wiring harness, and causing the problem of empty crimping or loose crimping.

[0056] Compared with the prior art, the application has the following advantages:

[0057] 1. In this invention, the connecting bracket and the pressure plate are pushed close to the top of the crimping table by the elastic force of the two springs, which forces the bottom of the pressure plate to squeeze the top of the multi-strand fiber core of the wire harness, thereby flattening the multi-strand fiber core so that it can be laid flat on the top of the crimping table, and at the same time fixing the wire harness to ensure the overall stability of the wire harness during the processing.

[0058] 2. In this invention, the cylinder output rod pushes the lower pressure block downwards. During the downward movement of the push pin, the two extrusion blocks are pushed towards the center at the same speed. The two extrusion blocks drive the extrusion steel ring and rubber block to move together. The two tension springs are stretched and stored. During this period, the support platform moves with the extrusion blocks and drives the linear slider to slide along the linear guide rail. Thus, through the sliding guidance effect of the linear guide rail and the linear slider, the stability and accuracy of the movement of the support platform, extrusion blocks, extrusion steel ring, and rubber block can be ensured. The movement of the two rubber blocks towards the center compresses the periphery of the multi-strand wire harness, causing the multi-strand fiber cores to stick together in sequence, so that the positioning mechanism can position each fiber core.

[0059] 3. In this invention, during the downward movement of the pressing block, the elastic force of the two springs also drives the boss, sinking rod, connecting platform, bearing seat, smooth rod, translation block and positioning block to move downward. When the two rubber blocks separate from the fiber core, the positioning groove opened on the top of the positioning block moves downward and directly locks onto the top of the outer wall of each fiber core. Through the limiting effect of the inner wall of the positioning groove on the outer wall of the fiber core, each fiber core is independently positioned.

[0060] 4. In this invention, as the pressing block continues to move downward, the second spring is compressed and stores energy. The pressing block slides downward along the outer wall of the two sinking rods, and drives the two pressing blocks and pins to move downward, pushing the rocker arm to rotate downward. The downward rotation of the rocker arm drives the horizontal shaft, rotating cylinder, spiral groove and annular groove to rotate together. Since the middle pin is slidably connected to the annular groove, the positions of the translation block and positioning block connected to the pin do not change. The remaining pins are slidably connected to the spiral groove. Therefore, after the spiral groove rotates, the remaining pins spread outward and drive the pins, translation blocks and positioning blocks connected to them to move together along the two smooth rods. The movement of the multiple positioning blocks drives the movement of the multiple positioning grooves together, separating the multiple fiber cores at equal distances, so that the crimping arm can simultaneously crimp the terminals of the multiple fiber cores.

[0085] Specifically, as the lower block 2010 continues to move downward, the spring 303 is compressed and stored, the lower block 2010 slides downward along the outer wall of the two sinking rods 301, and drives the two pressing blocks 3018 and the pins 3019 to move downward, pushing the rocker arm 3016 to rotate downward, the rocker arm 3016 drives the horizontal shaft 3011, the rotating drum 3012, the spiral groove 3013 and the ring groove 3014 to rotate together, since the middle one of the pins 3015 is in sliding connection with the ring groove 3014, the position of the translation block 307 and the positioning block 308 connected with the pin 3015 does not change, and the remaining pins 3015 are in sliding connection with the spiral groove 3013, so that after the spiral groove 3013 rotates, the remaining pins 3015 spread outward and drive the pins 3015, the translation block 307 and the positioning block 308 connected therewith to move along the two light poles 306, the movement of the positioning blocks 308 drives the positioning grooves 309 to move together, which separates the multiple cores at equal distances, so as to facilitate the crimping arm 400 to crimp the terminals of the multiple cores at the same time.

[0086] The multi-wire harness terminal crimping assembly all-in-one machine in the present scheme works by placing the wire harness on the top of the crimping table 101, and placing the multiple cores inside the wire harness on the bottom of the pressing plate 106, and by the elastic force of the two springs 107, the connecting bracket 105 and the pressing plate 106 are pushed towards the top of the crimping table 101, forcing the bottom of the pressing plate 106 to press the top of the multiple cores of the wire harness, thereby flattening the multiple cores and enabling them to be laid flat on the top of the crimping table 101 (as shown in the accompanying drawings), at this time, due to the pressing action of the pressing plate 106 on the multiple cores, they are laid flat on the top of the crimping table 101, but the distance between the adjacent two cores is random, so at this time, the multiple cores cannot be precisely crimped; Figure 4

[0087] ​Based on the above, it is necessary to do is, by the output rod of the cylinder 2011 down push down block 2010, down block 2010 down with the push plate 208 along with two push pin 209 down, two push pin 209 down respectively with two push bar 207 surface contact, so as to in the process of moving down with push pin 209, two extrusion block 204 to the middle of the same speed push, two extrusion block 204 with extrusion ring 205, rubber block 206 together with the movement, two tension spring 2016 stretch power storage, during, rely on the table 203 with extrusion block 204 together with the movement and drive linear slide 202 along the linear guide rail 201 slide, in turn through the linear guide rail 201 and linear slide 202 sliding guide effect, can guarantee the table 203, extrusion block 204, extrusion ring 205 and rubber block 206 moving stability and precision, while two rubber block 206 to the middle of the move, the surrounding extrusion of the multi strand wire bundle, so that the multi core in turn close together, and with the push pin 209 continue to move down, when the push pin 209 after the push bar 207 surface bending part, two push pin 209 to two push bar 207 to the middle of the extrusion force end, two tension spring 2016 of the resilience release, two linear slide 202, table 203, extrusion block 204, extrusion ring 205, rubber block 206 and push bar 207 to the periphery of the pull, make rubber block 206 and core separate, at this time, the pressure plate 106 is still extruded in the core top, therefore, the extruded core is not easy to loosen;

[0088] The downward movement of the pressing block 2010 is also driven by the elastic force of the two springs 303, which drives the boss 302, the sinking rod 301, the connecting platform 304, the bearing seat 305, the light pole 306, the translation block 307 and the positioning block 308 to move downward. When the two rubber blocks 206 are separated from the fiber core, the positioning groove 309 on the top of the positioning block 308 is just moved downward and directly clamped on the top of the outer wall of each fiber core. Through the limiting action between the inner wall of the positioning groove 309 and the outer wall of the fiber core, each fiber core is independently positioned. As the downward movement of the pressing block 2010 continues, the spring 303 is compressed and stored, the pressing block 2010 slides downward along the outer wall of the two sinking rods 301, and the two pressing blocks 3018 and the pin 3019 are driven to move downward, which pushes the rocker arm 3016 to rotate downward. The downward rotation of the rocker arm 3016 drives the horizontal shaft 3011, the rotating drum 3012, the spiral groove 3013 and the ring groove 3014 to rotate together. Since the middle toggle pin 3015 is in sliding connection with the ring groove 3014, the position of the translation block 307 and the positioning block 308 connected with the toggle pin 3015 does not change, while the remaining toggle pins 3015 are in sliding connection with the spiral groove 3013. Therefore, after the spiral groove 3013 rotates, the remaining multiple toggle pins 3015 move outward and spread, and drive the toggle pins 3015, the translation blocks 307 and the positioning blocks 308 connected therewith to move along the two light poles 306. The movement of the multiple positioning blocks 308 drives the multiple positioning grooves 309 to move, which separates the multiple fiber cores at equal distances, so as to facilitate the crimping of the multiple fiber cores by the crimping arm 400.

[0089] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to the embodiments without departing from the principles and spirit of the present application.
