Description

Technical Field

[0001] The present invention relates to the technical field of wire harness wiring and feeding, and in particular to a wire harness wiring terminal feeding device and method. Background Art

[0002] The low-voltage wiring harness is composed of wires that connect various parts of the automotive electrical system. The ends of the wiring harness are connected to various sensors, instruments, relays and switches through connectors (terminals). The low-voltage wiring harness terminals on existing cars are mostly made of zinc alloy. When the wiring harness terminals are crimped on the low-voltage wiring harness, the existing terminal machine places a whole terminal strip on the terminal machine and then presses down to realize the automatic terminal loading step. However, the existing terminal machine cannot feed the wiring harness, that is, it is necessary to manually place the low-voltage wiring harness at the crimping position of the terminal machine. This method requires manual holding and making the low voltage The crimping position of the wire harness is stable at the crimping position of the terminal machine, but the manual holding method is prone to shaking and instability, resulting in the terminal and the wire harness being crimped misaligned during the crimping process, which is likely to increase the defective rate of the low-voltage wire harness terminal crimping. Because the low-voltage wire harness is not made of hard material, its body will bend, etc., and the manual hand needs to be close to the crimping position to accurately place the crimping position of the low-voltage wire harness in the crimping position of the terminal machine. This method is relatively dangerous and can easily cause squeezing damage to the manual hand during the crimping process, resulting in production safety accidents. Summary of the Invention

[0003] In order to solve the above technical problems, the present invention provides a wiring harness terminal feeding device and method.

[0004] The technical solution is as follows: A wire harness terminal feeding device includes a base plate, a support frame fixedly connected to the top of the base plate, a chassis fixedly connected to the top of the support frame, a pressing module fixedly connected to the top of the chassis, a pressing head slidably connected to the pressing module, a crimping seat corresponding to the position of the pressing head fixedly connected to the upper surface of the chassis, a feeding module provided on the pressing module, and a wire feeding mechanism for intermittent wire feeding provided on the chassis; The wire feeding mechanism includes a slot provided on the chassis, the slot corresponds to the position of the crimping seat, and two guide plates are fixedly connected to the chassis. The two guide plates are provided with a guide groove on one side close to each other, and an opening is provided in the groove wall of the guide groove. A spring is fixedly connected to the inside of the opening, and the end of the spring away from the end connected to the opening is fixedly connected to a limiting block.

[0005] Furthermore, the pressing module is specifically composed of an adjusting knob and a main body block, and the pressing module is driven upward by a cylinder, and the feeding module is specifically composed of a shift rod, an adjusting spring, a pressing block and other components.

[0006] Furthermore, the guide groove is composed of two oblique grooves and two transverse grooves to form a parallelogram, and the two transverse grooves of the guide groove extend a distance to both sides. The limit block is flush with the groove wall of one of the oblique grooves of the guide groove, and a slope is provided on the end of the limit block away from the spring.

[0007] Furthermore, the wire feeding assembly also includes a fixed seat fixedly connected to the upper surface of the base plate, and two electric cylinders are rotatably connected to the fixed seat. A wire feeding block is rotatably connected to the telescopic shaft of the two electric cylinders, and a group of sliding rods are fixedly connected on both sides of the two wire feeding blocks. Each group of sliding rods slides inside the guide groove, and a wire groove is provided on the wire feeding block. Two rotating seats are fixedly connected to the wire feeding block, and a wire pressing block is rotatably connected to the two rotating seats, and a pressing groove is provided at the bottom of the wire pressing block.

[0008] Furthermore, the electric cylinders are staggered, with two being provided in each group of sliding rods.

[0009] Furthermore, the wire feeding assembly also includes two torsion springs arranged at the rotating connection between the wire pressing block and the rotating seat. The two ends of the two torsion springs are fixedly connected to the rotating seat and the wire pressing block respectively. A through hole is opened on the top of the wire pressing block. The inner wall of the through hole on the wire pressing block is fixedly connected to Spring 2. The top of Spring 2 is fixedly connected to a fastening rod. The sides of the two guide plates close to each other are fixedly connected to a release rod.

[0010] Furthermore, the bottom of one end of the pressing block away from the rotation connection with the pressing block is set as an inclined surface, the fastening rod slides inside the through hole of the pressing block, and the bottom of the fastening rod protrudes from the groove wall of the pressing groove.

[0011] A method for feeding wiring harness terminals: Step 1: Place the zinc alloy terminal strip to be crimped on the chassis, adjust it so that the first zinc alloy terminal overlaps with the crimping seat, and place the low-voltage wire harness on the crimping seat to complete the initial positioning.

[0012] Step 2: Place the low-voltage wire harness into the wire slot of the wire feeding block. The wire pressing block presses down through the pressing slot and cooperates with the tightening rod to stretch the spring 2 to firmly press the wire harness into the wire slot.

[0013] Step 3: Start two electric cylinders, one to retract and the other to extend. The extended electric cylinder pushes the bottom wire feeding block upward, and the retracted electric cylinder pulls the top wire feeding block downward, triggering the wire feeding blocks to move alternately.

[0014] Step 4: The two wire feeding blocks move along the guide groove through the sliding rod, first moving horizontally, then entering the inclined groove to realize oblique upward / downward movement, and then entering the top horizontal groove to move horizontally. When the sliding rod hits the limit block, spring 1 is compressed and reset by the rear spring 1. The limit block remains coincident with the inclined surface of the guide groove.

[0015] Step 5: When the bottom wire feeding block moves, the inclined surface of the wire pressing block contacts the release rod and tilts up, the torsion spring relaxes, and the wire harness is temporarily not tightened; after moving horizontally, the wire pressing block separates from the release rod, and the torsion spring resets to drive the wire pressing block downward, and the wire harness is re-tightened through the pressure groove.

[0016] Step 6: The bottom wire feeding block sends the uncrimped wire harness to the crimping seat for crimping, and the top wire feeding block brings the crimped wire harness to the bottom. The wire pressing block contacts the release rod and tilts up, the wire harness is loosened, and it is manually removed and reloaded to complete the feeding cycle.

[0017] As described above, the beneficial effects of the wire harness wiring zinc alloy terminal feeding device and method of the present invention are as follows: The automatic feeding and unloading of the wires by two feeding blocks provides space for manual operation when placing low-voltage wire harnesses. Compared with the existing manual placement of low-voltage wire harnesses, which requires the hand to be close to the crimping seat for accurate placement, the risk of accidental injury caused by the hand being too close to the crimping seat is reduced, and the safety of the low-voltage wire harness crimping zinc alloy terminals is improved. By alternately driving the low-voltage wire harness to move by two wire feeding blocks, time can be provided for manual placement of the low-voltage wire harness, thereby avoiding affecting processing efficiency. At the same time, the wire feeding blocks can accurately drive the low-voltage wire harness to the crimping seat, thereby enabling the lower pressure head to accurately crimp the zinc alloy terminal to the low-voltage wire harness, thereby avoiding the existing problem of crimping failure or crimping misalignment caused by inaccurate placement of the low-voltage wire harness by manual labor, thereby reducing the crimping defective rate of the zinc alloy terminal of the low-voltage wire harness; The operation of tightening the low-voltage wire harness by tightening the rod can prevent the low-voltage wire harness from loosening and falling during movement, and also avoid the problem of misalignment and offset during crimping of the zinc alloy terminal. In addition, it can also prevent the situation of pulling and falling during crimping, thereby improving the stability of the low-voltage wire harness crimping zinc alloy terminal.

DETAILED DESCRIPTION

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0021] The embodiments provided by the present invention will be described in detail below: like Figures 1 to 6 As shown, a wiring harness terminal feeding device includes a base plate 1, a support frame 2 is fixedly connected to the top of the base plate 1, a chassis 3 is fixedly connected to the top of the support frame 2, a pressing module 4 is fixedly connected to the top of the chassis 3, a pressing head 42 is slidably connected to the pressing module 4, a crimping seat 41 corresponding to the position of the pressing head 42 is fixedly connected to the upper surface of the chassis 3, a feeding module 5 for feeding zinc alloy terminals is provided on the pressing module 4, and a wire feeding mechanism for intermittent wire feeding is provided on the chassis 3; It should be noted that the pressing module 4 and the feeding module 5 are both existing technologies. The pressing module 4 is specifically composed of an adjusting knob and a main block. The adjusting knob is used to adjust the pressing depth of the pressing head 42, and the pressing module 4 is driven upward by the cylinder. The feeding module 5 is specifically composed of a lever, an adjusting spring, a pressing block and other components. The lever is used to push the zinc alloy terminal strip to move. The main block on the pressing module 4 can push the pressing block when the cylinder drives it to move downward. The pressing block can make the lever swing, thereby pushing the zinc alloy terminal strip to move. In addition, the adjusting spring can adjust the movement distance of the lever to push the zinc alloy terminal strip. Other components will not be described in detail here.

[0022] The wire feeding mechanism includes a slot 61 provided on the chassis 3, and the slot 61 corresponds to the position of the crimping seat 41. Two guide plates 62 symmetrical with respect to the crimping seat 41 are fixedly connected to the chassis 3. A guide groove 63 is provided on the side of the two guide plates 62 close to each other. An opening 64 is provided in the groove wall of the guide groove 63. A spring 65 is fixedly connected to the inside of the opening 64, and a limit block 66 is fixedly connected to the end of the spring 65 away from the opening 64.

[0023] It should be noted that the guide groove 63 is a parallelogram consisting of two oblique grooves and two transverse grooves, and the two transverse grooves of the guide groove 63 extend a distance to both sides. One side wall of the limit block 66 is flush with the groove wall of one of the oblique grooves of the guide groove 63, and the end of the limit block 66 away from the spring 1 65 is provided with an inclined surface.

[0024] Specifically, when crimping the end of the low-voltage wiring harness, the zinc alloy terminal strip to be crimped is placed on the chassis 3, and the first zinc alloy terminal of the zinc alloy terminal strip is pushed to a position that coincides with the crimping seat 41. At the same time, the low-voltage wiring harness also needs to be placed on the crimping seat 41. After starting the oil cylinder, the pressing module 4 moves downward. When the pressing module 4 moves downward, the lever of the feed module 5 will be tilted. In addition, the pressing module 4 will also drive the pressing head 42 to move downward. At this time, the downward-moving pressing head 42 will crimp the first section of the zinc alloy terminal with the low-voltage wiring harness. After crimping the zinc alloy terminal, the oil cylinder causes the pressing module 4 to move upward. When the pressing module 4 moves upward, the lever will push the zinc alloy terminal strip downward to the side close to the crimping seat 41 by the distance of a zinc alloy terminal. In this way, the zinc alloy terminal can be continuously crimped on the low-voltage wiring harness.

[0025] It should be noted that the above is only the operation process of the existing terminal block machine, and other functions will not be described in detail here.

[0026] like Figures 6 to 8 As shown, the wire feeding assembly also includes a fixed seat 67 fixedly connected to the upper surface of the base plate 1, and two electric cylinders 68 are rotatably connected to the fixed seat 67. A wire feeding block 69 is rotatably connected to the telescopic shaft of the two electric cylinders 68. A group of slide rods 610 are fixedly connected on both sides of the two wire feeding blocks 69. Each group of slide rods 610 slides inside the guide groove 63. A wire groove 611 is provided on the wire feeding block 69. Two rotating seats 612 are fixedly connected to the wire feeding block 69. A wire pressing block 613 is rotatably connected to the two rotating seats 612, and a pressing groove 614 is provided at the bottom of the wire pressing block 613.

[0027] It should be noted that the electric cylinders 68 are staggered so that they will not interfere with each other when they are extended to push the wire feeding block 69 to move, and one of the electric cylinders 68 is extended and the other is not extended. The extended electric cylinder 68 passes through the wire feeding block 69 so that the two groups of slide bars 610 on it are located in the horizontal groove at the top of the guide groove 63, and the unextended electric cylinder 68 passes through the wire feeding block 69 so that the two groups of slide bars 610 on it are located in the horizontal groove at the bottom of the guide groove 63. Each group of slide bars 610 is provided with two, for a total of four groups, which are used to maintain parallelism with the shape of the guide groove 63 when sliding in the slide bar 610, that is, to keep the wire feeding block 69 stable during movement and avoid rotation.

[0028] Specifically, in the process of placing the low-voltage harness, the low-voltage harness can be placed on the wire groove 611 first, and then the wire pressing block 613 will press the low-voltage harness into the wire groove 611 through the pressing groove 614 to avoid the harness from being misplaced and loose during movement. Then, the two electric cylinders 68 are started, and the electric cylinders 68 are respectively contracted and extended. Figure 5 As shown, the extended electric cylinder 68 will drive a wire feeding block 69 at the bottom to move upward, and the retracted electric cylinder 68 will pull a wire feeding block 69 at the top to move downward. The wire feeding block 69 at the bottom will first move horizontally for a distance under the sliding action of the slide bar 610 in the guide groove 63, and then the two slide bars 610 will sequentially enter an oblique groove on the right side of the guide groove 63 under the limiting action of the limit block 66. Figure 5When the sliding rod 610 on the wire feeding block 69 moves to the intersection of the oblique groove and the transverse groove in the guide groove 63, it is in a state of being pulled downward, which enables the sliding rod 610 on the wire feeding block 69 to enter the guide groove 63 obliquely in turn. When the sliding rod 610 on the wire feeding block 69 moves to the lowest position of the guide groove 63 oblique groove, it will enter the horizontal groove position of the guide groove 63 in sequence. At this time, the wire feeding block 69 is in an inclined state under the sliding action of the sliding rod 610 in the guide groove 63 oblique groove. At the same time, when the wire feeding block 69 moves, the electric cylinder 68 can also rotate on the fixed seat 67. After the wire feeding block 69 moves horizontally for a distance, the sliding rod 610 on it will contact the inclined surface of the limit block 66, and then the wire feeding block 69 continues to move through the sliding rod 6 10 pushes the limit block 66 to move toward the inside of the opening 64, and the limit block 66 compresses the spring 1 65. When the slide bar 610 passes the limit block 66, that is, the slide bar 610 no longer conflicts with the limit block 66, the limit block 66 moves upward inside the opening 64 under the elastic reset action of the spring 1 65. At this time, the limit block 66 continues to keep the inclined surface of the guide groove 63 in a state of coincidence. Then, the wire feeding block 69 moves to the original top wire feeding block 69 position, and the bottom wire feeding block 69 moves to drive the unpressed wire feeding block 69. The low-voltage wire harness moves to the crimping seat 41 for crimping. The movement of a wire feeding block 69 at the top will drive the crimped low-voltage wire harness to move to the bottom for easy picking. The automatic feeding operation of the two wire feeding blocks 69 can provide space for manual placement of the low-voltage wire harness. Compared with the existing manual placement of the low-voltage wire harness, which requires the hand to be close to the crimping seat 41 to be accurately placed, the risk of accidental injury caused by the manual hand being too close to the crimping seat 41 is reduced, and the safety of the low-voltage wire harness during crimping zinc alloy terminals is improved.

[0029] It should be noted that, referring to Figure 5 and Figure 6 As shown, the sliding rods 610 on the two wire feeding blocks 69 move in the counterclockwise direction in the guide groove 63, and the two wire feeding blocks 69 move simultaneously, so there will be no interference during the movement. The two wire feeding blocks 69 alternately drive the low-voltage wire harness to move, which can provide manual time for placing the low-voltage wire harness and avoid affecting the processing efficiency. At the same time, the wire feeding blocks 69 can accurately drive the low-voltage wire harness to the crimping seat 41, and then the lower pressure head 42 can accurately crimp the zinc alloy terminal to the low-voltage wire harness, avoiding the existing problem of manual placement of the low-voltage wire harness causing crimping failure or crimping misalignment, and reducing the crimping defective rate of the zinc alloy terminal of the low-voltage wire harness.

[0030] like Figure 5 and Figure 8 As shown, the wire feeding assembly also includes two torsion springs 615 that are sleeved on the rotating connection between the wire pressing block 613 and the rotating seat 612. The two ends of the two torsion springs 615 are fixedly connected to the rotating seat 612 and the wire pressing block 613 respectively. A through hole is provided on the top of the wire pressing block 613. The inner wall of the through hole on the wire pressing block 613 is fixedly connected to a spring 2 616. The top of the spring 2 616 is fixedly connected to a fastening rod 617. The two guide plates 62 are fixedly connected to a release rod 618 on the side close to each other.

[0031] It should be noted that the bottom of one end of the wire pressing block 613 away from the rotating connection with the rotating seat 612 is set as an inclined surface, and the fastening rod 617 slides inside the through hole of the wire pressing block 613, and the bottom of the fastening rod 617 protrudes from the groove wall of the pressing groove 614.

[0032] Specifically, during the movement of the two wire feeding blocks 69, the inclined surface of the wire pressing block 613 on the bottom wire feeding block 69 will be in conflict with the release rod 618, thereby causing the wire pressing block 613 to be in a tilted state. For details, please refer to Figure 5When the wire feeding block 69 moves laterally for a certain distance, the inclined surface of the wire pressing block 613 no longer conflicts with the releasing rod 618, and then, under the elastic reset action of the torsion spring 615, the wire pressing block 613 swings downward with the rotating seat 612 as the axis and presses the low-voltage wire harness into the wire groove 611 through the pressing groove 614. In addition, when the pressing groove 614 of the wire pressing block 613 presses the low-voltage wire harness, the fastening rod 617 on it will conflict with the low-voltage wire harness. After the fastening rod 617 conflicts with the low-voltage wire harness, the spring 2 616 will be stretched, thereby ensuring the stable compression of the low-voltage wire harness. At the same time, the wire feeding block 69 at the top will drive the low-voltage wire harness crimped in the wire groove 611 to be synchronously When the wire feeding block 69 moves, the wire feeding block 69 can automatically take out the crimped low-voltage wire harness. When the wire feeding block 69 moves to the original position of the bottom wire feeding block 69, the inclined surface of the wire pressing block 613 on it will contact the release rod 618. The wire pressing block 613 will be restricted by the release rod 618 and will tilt upward with the rotating seat 612 as the axis. After the wire pressing block 613 tilts up, the tightening rod 617 will no longer squeeze the low-voltage wire harness. At this time, the staff can smoothly take away the low-voltage wire harness and then put the low-voltage wire harness to be crimped back on the wire groove 611. The operation of tightening the low-voltage wire harness by the tightening rod 617 can avoid the low-voltage wire harness from loosening and falling during the movement process, and also avoid the problem of misalignment and offset in the process of crimping the zinc alloy terminal. In addition, it can also prevent the situation of pulling and falling during crimping, thereby improving the stability of the low-voltage wire harness crimping the zinc alloy terminal.

[0033] It should be noted that during the placement of the low-voltage wiring harness, the low-voltage wiring harness needs to pass between the pressing groove 614 of the wire pressing block 613 and the wire groove 611, and the position where the low-voltage wiring harness needs to be crimped protrudes from the wire feeding block 69, so that the low-voltage wiring harness can be driven to the crimping seat 41 when the wire feeding block 69 moves.

[0034] A method for feeding wiring harness terminals: Step 1: Place the zinc alloy terminal strip to be crimped on the chassis 3, adjust it so that the first zinc alloy terminal overlaps with the crimping seat 41, and place the low-voltage wire harness on the crimping seat 41 to complete the initial positioning.

[0035] Step 2: Place the low-voltage wire harness into the wire groove 611 of the wire feeding block 69 , and press the wire pressing block 613 downward through the pressing groove 614 , cooperating with the tightening rod 617 to stretch the second spring 616 , and stably press the wire harness into the wire groove 611 .

[0036] Step 3: Start the two electric cylinders 68, one to contract and the other to extend. The extended electric cylinder 68 pushes the bottom wire feeding block 69 upward, and the contracted electric cylinder 68 pulls the top wire feeding block 69 downward, triggering the wire feeding blocks 69 to move alternately.

[0037] Step 4: The two wire feeding blocks 69 move along the guide groove 63 through the slide bar 610, first moving horizontally, then entering the inclined groove to realize oblique upward / downward movement, and then entering the top horizontal groove to move horizontally. When the slide bar 610 hits the limit block 66, the spring 1 65 is compressed and reset by the rear spring 1 65. The limit block 66 remains coincident with the inclined surface of the guide groove 63.

[0038] Step 5: When the bottom wire feeding block 69 moves, the inclined surface of the wire pressing block 613 contacts the release rod 618 and tilts up, the torsion spring 615 relaxes, and the wire harness is temporarily not compressed; after moving horizontally, the wire pressing block 613 disengages from the release rod 618, and the torsion spring 615 resets and drives the wire pressing block 613 to press down, and the wire harness is compressed again through the pressure groove 614.

[0039] Step 6: The bottom wire feeding block 69 sends the uncrimped wire harness to the crimping seat 41 for crimping, and the top wire feeding block 69 brings the crimped wire harness to the bottom. Its wire pressing block 613 contacts the release rod 618 and tilts up, the wire harness is loosened, and is manually removed and reloaded to complete the feeding cycle.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

A method for feeding wire harness terminal blocks, according to the device for feeding wire harness terminal blocks as claimed in claim 7, characterized in that: Methods include: Step 1: Place the zinc alloy terminal strip to be crimped on the chassis (3), adjust it so that the first zinc alloy terminal overlaps with the crimping seat (41), and place the low-voltage wiring harness on the crimping seat (41) to complete the initial positioning; Step 2: Place the low-voltage wire harness into the wire groove (611) of the wire feeding block (69), press the wire pressing block (613) downward through the pressing groove (614), and cooperate with the tightening rod (617) to stretch the spring 2 (616) to stably press the wire harness into the wire groove (611); Step 3: Start two electric cylinders (68), one to contract and the other to extend, the extended electric cylinder (68) pushes the bottom wire feeding block (69) upward, and the contracted electric cylinder (68) pulls the top wire feeding block (69) downward, triggering the wire feeding blocks (69) to move alternately; Step 4: The two wire feeding blocks (69) move along the guide groove (63) through the slide bar (610), first move horizontally, then enter the inclined groove to realize oblique upward / downward movement, and then enter the top horizontal groove to move horizontally. When the slide bar (610) hits the limit block (66), the spring 1 (65) is compressed and reset by the rear spring 1 (65). The limit block (66) remains coincident with the inclined surface of the guide groove (63); Step 5: When the bottom wire feeding block (69) moves, the inclined surface of the wire pressing block (613) contacts the release rod (618) and tilts up, the torsion spring (615) relaxes, and the wire harness is temporarily not compressed; after the horizontal movement, the wire pressing block (613) is separated from the release rod (618), and the torsion spring (615) is reset to drive the wire pressing block (613) to press down, and the wire harness is compressed again through the pressure groove (614); Step 6: The bottom wire feeding block (69) sends the uncrimped wire harness to the crimping seat (41) for crimping, and the top wire feeding block (69) brings the crimped wire harness to the bottom, and its wire pressing block (613) contacts the release rod (618) and tilts up, the wire harness is loosened, and is manually removed and reloaded to complete the feeding cycle.
