Description

Technical Field

[0001] This invention relates to the field of wire harness wiring and feeding technology, and more specifically, to a wire harness terminal feeding device and method. Background Technology

[0002] Low-voltage wiring harnesses consist of wires connecting various parts of an automotive electrical system. The ends of the harness connect to various sensors, instruments, relays, and switches via connectors (terminals). Currently, most low-voltage wiring harness terminals in automobiles are made of zinc alloy. When crimping the wiring harness terminals onto the low-voltage harness, existing crimping machines place a whole terminal strip on the machine and then press down to automate the terminal feeding process. However, existing crimping machines cannot feed the wiring harness itself; that is, the low-voltage wiring harness must be manually placed in the crimping position of the machine. This method requires manual handling and pressure application. The crimping position of the wire harness is stable at the crimping position of the terminal crimping machine. However, manual hand-held crimping is prone to shaking and instability, which can lead to misalignment of the terminal and wire harness during the crimping process. This can easily increase the defect rate of low-voltage wire harness terminal crimping. Because low-voltage wire harnesses are not made of rigid materials, their bodies may bend. Therefore, it is necessary for the manual hand to be close to the crimping position to accurately place the low-voltage wire harness in the crimping position of the terminal crimping machine. This method is relatively dangerous and can easily cause crushing injuries to the manual hand during the crimping process, resulting in production safety accidents. Summary of the Invention

[0003] To solve the above-mentioned technical problems, the present invention provides a wire harness terminal feeding device and method.

[0004] The technical solution is as follows:

[0005] 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.

[0006] The wire feeding mechanism includes a slot on the chassis, the slot corresponding to the position of the crimping seat. Two guide plates are fixedly connected to the chassis. The two guide plates have guide grooves on their sides that are close to each other. An opening is made in the groove wall of the guide groove. A spring is fixedly connected inside the opening. A limit block is fixedly connected to the end of the spring away from the opening.

[0007] Furthermore, the pressing module is specifically composed of an adjustment knob and a main block, and the pressing module is driven upward by a hydraulic cylinder. The feeding module is specifically composed of components such as a lever, an adjustment spring, and a pressing block.

[0008] Furthermore, the guide groove is a parallelogram composed of two inclined grooves and two transverse grooves, and the two transverse grooves of the guide groove extend to both sides by a certain distance. The limiting block is flush with the groove wall of one of the inclined grooves of the guide groove, and the end of the limiting block away from the spring is provided with an inclined surface.

[0009] Furthermore, the wire feeding assembly also includes a fixed base fixedly connected to the upper surface of the base plate. Two electric cylinders are rotatably connected to the fixed base. A wire feeding block is rotatably connected to the telescopic shaft of each of the two electric cylinders. A set of sliding rods is fixedly connected to both sides of the two wire feeding blocks. Each set of sliding rods slides inside the guide groove. A wire groove is opened on the wire feeding block. Two rotating seats are fixedly connected to the wire feeding block. A wire pressing block is rotatably connected to both rotating seats. A pressing groove is opened at the bottom of the wire pressing block.

[0010] Furthermore, the electric cylinders are arranged in an alternating pattern, with two cylinders in each group of slides.

[0011] Furthermore, the wire feeding assembly also includes two torsion springs sleeved at the rotatable 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. A second spring is fixedly connected to the inner wall of the through hole on the wire pressing block. A fastening rod is fixedly connected to the top of the second spring. A release rod is fixedly connected to the side of the two guide plates that are close to each other.

[0012] Furthermore, the bottom of the end of the pressure block away from the rotatable connection point of the pressure block is set as an inclined surface, and the fastening rod slides inside the through hole of the pressure block, with the bottom of the fastening rod protruding from the groove wall of the pressure groove.

[0013] A method for feeding wire harness terminals:

[0014] Step 1: Place the zinc alloy terminal strip to be crimped on the chassis, and adjust it so that the first zinc alloy terminal coincides with the crimping seat. At the same time, place the low-voltage wire harness on the crimping seat to complete the initial positioning.

[0015] Step 2: Place the low-voltage wire harness into the wire groove of the wire feeding block. The wire pressing block presses down through the groove, and in conjunction with the tension spring 2 of the fastening rod, the wire harness is stably pressed into the wire groove.

[0016] Step 3: Activate two electric cylinders, one retracting and the other extending. The extending electric cylinder pushes the bottom wire feeding block upward, while the retracting electric cylinder pulls the top wire feeding block downward, triggering the wire feeding blocks to move alternately.

[0017] Step 4: The two wire feeding blocks move along the guide groove via the slide rod. First, they move laterally, then enter the inclined groove to move diagonally upward / downward, and then enter the top horizontal groove to move laterally. When the slide rod touches the limit block, it compresses the first spring. After passing through, the first spring resets, and the limit block remains aligned with the inclined surface of the guide groove.

[0018] Step 5: When the bottom wire feeding block moves, the inclined surface of the wire pressing block abuts against the release rod and lifts up, the torsion spring relaxes, and the wire harness is not pressed tightly for the time being; after moving laterally, the wire pressing block disengages from the release rod, the torsion spring resets and drives the wire pressing block to press down, and the wire harness is pressed tightly again through the pressing groove.

[0019] Step Six: The bottom wire feeding block delivers the uncrimped wire harness to the crimping seat for crimping, while the top wire feeding block brings the crimped wire harness to the bottom. The crimping block's contact release lever lifts up, the wire harness loosens, and it is manually removed before being reloaded, completing the feeding cycle.

[0020] 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:

[0021] The automatic feeding operation of two wire feeding blocks provides space for manual placement of low-voltage wire harnesses. Compared with the existing method of manually placing low-voltage wire harnesses, which requires the hand to be close to the crimping seat for accurate placement, this reduces the risk of accidental injury caused by the hand being too close to the crimping seat and improves the safety of low-voltage wire harness crimping zinc alloy terminals.

[0022] By using two wire feeding blocks to alternately drive the low-voltage wire harness, time can be provided for manual placement of the low-voltage wire harness, thus avoiding affecting processing efficiency. At the same time, the wire feeding blocks can accurately drive the low-voltage wire harness onto the crimping seat, thereby enabling the lower crimping head to accurately crimp the zinc alloy terminal onto the low-voltage wire harness. This avoids the problems of crimping failure or misalignment caused by inaccurate placement of the low-voltage wire harness when manually placing it, and reduces the defect rate of crimping zinc alloy terminals of low-voltage wire harness.

[0023] The operation of tightening the low-voltage wire harness with the fastening rod can prevent the low-voltage wire harness from loosening and falling off during the initial movement. It also prevents misalignment and displacement during the crimping of zinc alloy terminals and prevents pulling and falling off during crimping, thus improving the stability of the low-voltage wire harness crimping to zinc alloy terminals.

[0035] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0036] The embodiments provided by the present invention will be described in detail below:

[0037] like Figures 1 to 6 As shown, a wire harness terminal feeding device includes a base plate 1, a support frame 2 fixedly connected to the top of the base plate 1, a chassis 3 fixedly connected to the top of the support frame 2, a pressing module 4 fixedly connected to the top of the chassis 3, a pressing head 42 slidably connected to the pressing module 4, a crimping seat 41 corresponding to the position of the pressing head 42 fixedly connected to the upper surface of the chassis 3, a feeding module 5 for feeding zinc alloy terminals on the pressing module 4, and a wire feeding mechanism for intermittent wire feeding on the chassis 3.

[0038] It should be noted that both the pressing module 4 and the feeding module 5 are existing technologies. The pressing module 4 is specifically composed of an adjustment knob and a main block. The adjustment knob is used to adjust the pressing depth of the pressing head 42. The pressing module 4 is driven upward by a hydraulic 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. When the main block on the pressing module 4 moves downward by the hydraulic cylinder, it can push the pressing block. 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 distance the lever pushes the zinc alloy terminal strip. Other components will not be described in detail here.

[0039] The wire feeding mechanism includes a slot 61 on the chassis 3, which corresponds to the position of the crimping seat 41. Two guide plates 62 symmetrical about the crimping seat 41 are fixedly connected to the chassis 3. The two guide plates 62 are provided with guide grooves 63 on their sides that are close to each other. An opening 64 is provided in the groove wall of the guide groove 63. A spring 65 is fixedly connected inside the opening 64. A limit block 66 is fixedly connected to the end of the spring 65 away from the opening 64.

[0040] It should be noted that the guide groove 63 is a parallelogram composed of two inclined grooves and two transverse grooves, and the two transverse grooves of the guide groove 63 extend to both sides by a certain distance. One side wall of the limiting block 66 is flush with the groove wall of one of the inclined grooves of the guide groove 63, and the end of the limiting block 66 away from the spring 65 is provided with an inclined surface.

[0041] Specifically, when crimping the ends of the low-voltage wire 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 the position coinciding with the crimping seat 41. At the same time, the low-voltage wire harness is placed on the crimping seat 41. After the hydraulic cylinder is activated, the pressing module 4 moves downward. When the pressing module 4 moves downward, the lever of the feed module 5 is raised. In addition, the pressing module 4 will also drive the pressing head 42 to move downward. At this time, the pressing head 42 will crimp the first section of zinc alloy terminal to the low-voltage wire harness. After crimping the zinc alloy terminal, the hydraulic cylinder makes the pressing module 4 move upward. When the pressing module 4 moves upward, the lever pushes the zinc alloy terminal strip downward to move one zinc alloy terminal distance closer to the crimping seat 41. By repeating this process, the zinc alloy terminal can be continuously crimped onto the low-voltage wire harness.

[0042] It should be noted that the above only describes the operation of the existing terminal block machine; other functions will not be elaborated upon here.

[0043] like Figures 6 to 8As shown, the wire feeding assembly also includes a fixed base 67 fixedly connected to the upper surface of the base plate 1. Two electric cylinders 68 are rotatably connected to the fixed base 67. A wire feeding block 69 is rotatably connected to the telescopic shaft of each of the two electric cylinders 68. A set of sliding rods 610 are fixedly connected to both sides of the two wire feeding blocks 69. Each set of sliding rods 610 slides inside the guide groove 63. A wire groove 611 is opened 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 both rotating seats 612. A pressing groove 614 is opened at the bottom of the wire pressing block 613.

[0044] It should be noted that the electric cylinders 68 are staggered to prevent them from interfering with each other when they extend and push the wire feeding block 69. One electric cylinder 68 is extended while the other is not. The extended electric cylinder 68 is positioned in the horizontal groove at the top of the guide groove 63 via the wire feeding block 69, while the non-extended electric cylinder 68 is positioned in the horizontal groove at the bottom of the guide groove 63 via the wire feeding block 69. Each set of sliding rods 610 has two rods, for a total of four sets. This ensures that the sliding rods 610 remain parallel to the shape of the guide groove 63, thus maintaining the stability of the wire feeding block 69 during movement and preventing rotation.

[0045] Specifically, during the placement of the low-voltage wire harness, the low-voltage wire harness can first be placed on the wire groove 611. Then, the wire pressing block 613 will press the low-voltage wire harness into the wire groove 611 through the pressing groove 614 to prevent the wire harness from becoming misaligned or loose during movement. Then, the two electric cylinders 68 are activated, and the electric cylinders 68 retract and extend respectively, as described above. Figure 5 As shown, the extending electric cylinder 68 drives a bottom wire feeding block 69 to move upward, and the retracting electric cylinder 68 pulls a top wire feeding block 69 downward. The bottom wire feeding block 69 moves laterally a certain distance under the sliding action of the slide rod 610 in the guide groove 63. Then, under the limiting action of the limiting block 66, the two slide rods 610 sequentially enter an inclined groove on the right side of the guide groove 63. (Refer to...) Figure 5On the right side, the slide rod 610 will cause the wire feeding block 69 to move obliquely upward. When the slide rod 610 moves to the horizontal groove at the top of the guide groove 63, it will cause the wire feeding block 69 to move laterally to the original position of the top wire feeding block 69. At the same time, the top wire feeding block 69 will move laterally a certain distance. When the slide rod 610 on the wire feeding block 69 moves to the intersection of the oblique groove and the horizontal groove in the guide groove 63, it is in a downward pulling state, which allows the slide rod 610 on the wire feeding block 69 to enter the oblique groove of the guide groove 63 in sequence. The position of the slot is such that when the slide rod 610 on the wire feeding block 69 moves to the lowest position of the inclined slot of the guide slot 63, it will sequentially enter the horizontal slot position of the guide slot 63. At this time, the wire feeding block 69 is in an inclined state under the sliding action of the slide rod 610 in the inclined slot of the guide slot 63. At the same time, when the wire feeding block 69 moves, the electric cylinder 68 will also rotate on the fixed seat 67. After the wire feeding block 69 moves laterally for a certain distance, the slide rod 610 on it will abut against the inclined surface of the limit block 66. Then, as the wire feeding block 69 continues to move, the slide rod 610 will... 10. Pushing the limiting block 66 into the opening 64, the limiting block 66 compresses the spring 65. When the slide rod 610 passes the limiting block 66, that is, when the slide rod 610 no longer abuts against the limiting block 66, the limiting block 66 moves upward inside the opening 64 under the elastic restoring action of the spring 65. At this time, the limiting block 66 continues to coincide with the inclined surface of the guide groove 63. Then, the wire feeding block 69 moves to the original position of the top wire feeding block 69. When the bottom wire feeding block 69 moves, it will drive the unpressed wire feeding block. The low-voltage wire harness moves onto the crimping seat 41 for crimping. A wire feeding block 69 at the top moves the crimped low-voltage wire harness to the bottom for easy retrieval. The automatic feeding operation of the two wire feeding blocks 69 provides space for manual placement of the low-voltage wire harness. Compared to the existing method where manual placement of low-voltage wire harness requires the hand to be close to the crimping seat 41 for accurate placement, this reduces the risk of accidental injury caused by the hand being too close to the crimping seat 41 and improves the safety of the low-voltage wire harness crimping zinc alloy terminals.

[0046] 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 counterclockwise in the guide groove 63. The two wire feeding blocks 69 move simultaneously, thus avoiding interference during the movement. By having the two wire feeding blocks 69 alternately drive the low-voltage wire harness, time can be provided for manual placement of the low-voltage wire harness, avoiding any impact on processing efficiency. At the same time, the wire feeding blocks 69 can accurately drive the low-voltage wire harness onto the crimping seat 41, thereby enabling the lower crimping head 42 to accurately crimp the zinc alloy terminal onto the low-voltage wire harness. This avoids the problem of inaccurate placement of the low-voltage wire harness during manual placement, which can lead to crimping failure or misalignment, and reduces the defect rate of the zinc alloy terminal crimping of the low-voltage wire harness.

[0047] like Figure 5 and Figure 8 As shown, the wire feeding assembly also includes two torsion springs 615 sleeved at the rotatable 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 opened on the top of the wire pressing block 613. A second spring 616 is fixedly connected to the inner wall of the through hole on the wire pressing block 613. A fastening rod 617 is fixedly connected to the top of the second spring 616. A release rod 618 is fixedly connected to the side of the two guide plates 62 that are close to each other.

[0048] It should be noted that the bottom of the end of the pressure block 613 away from the rotatable connection with the rotating seat 612 is set as an inclined surface, and the fastening rod 617 slides inside the through hole of the pressure block 613, with the bottom of the fastening rod 617 protruding from the groove wall of the pressure groove 614.

[0049] Specifically, during the movement of the two wire feeding blocks 69, the inclined surface of the pressure block 613 on the bottom wire feeding block 69 will be in contact with the release lever 618, thereby causing the pressure block 613 to be in a tilted state. See reference [link / reference needed] for details. Figure 5Simultaneously, the pressure block 613 causes the torsion spring 615 between it and the rotating seat 612 to be torsionally deformed. That is, at this time, the pressure block 613 does not press the low-voltage wire harness placed on the wire groove 611 through the pressure groove 614. However, when the wire feeding block 69 moves laterally a certain distance, the inclined surface of the pressure block 613 no longer abuts against the release rod 618. Then, under the elastic reset action of the torsion spring 615, the pressure block 613 swings downward around the rotating seat 612 as the axis and presses the low-voltage wire harness into the wire groove 611 through the pressure groove 614. In addition, when the pressure groove 614 of the pressure block 613 presses the low-voltage wire harness, the fastening rod 617 on it will abut against the low-voltage wire harness. After the fastening rod 617 abuts against the low-voltage wire harness, it will stretch the second spring 616, thereby ensuring the stable pressing of the low-voltage wire harness. At the same time, the top wire feeding block 69 will drive the low-voltage wire harness pressed into the wire groove 611 to move synchronously. The moving wire feeding block 69 can automatically remove 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 crimping block 613 on it will contact the release rod 618. Under the restriction of the release rod 618, the crimping block 613 will tilt upward around the rotating seat 612. After the crimping block 613 tilts up, the fastening rod 617 will no longer squeeze the low-voltage wire harness. At this time, the operator can easily remove the low-voltage wire harness and then place the low-voltage wire harness to be crimped back on the wire groove 611. The operation of pressing the low-voltage wire harness with the fastening rod 617 can prevent the low-voltage wire harness from loosening and falling during the movement process. It can also prevent misalignment and displacement during the crimping of zinc alloy terminals. In addition, it can also prevent the low-voltage wire harness from being pulled off during crimping, thus improving the stability of the low-voltage wire harness crimping zinc alloy terminals.

[0050] It should be noted that during the placement of the low-voltage wire harness, the low-voltage wire harness needs to pass through the crimping groove 614 and the wire groove 611 of the crimping block 613, and the position where the low-voltage wire harness needs to be crimped protrudes from the wire feeding block 69, so that the low-voltage wire harness can be driven onto the crimping seat 41 when the wire feeding block 69 moves.

[0051] A method for feeding wire harness terminals:

[0052] Step 1: Place the zinc alloy terminal strip to be crimped on the chassis 3, and adjust it so that the first zinc alloy terminal coincides with the crimping seat 41. At the same time, place the low voltage wire harness on the crimping seat 41 to complete the initial positioning.

[0053] Step 2: Place the low-voltage wire harness into the wire groove 611 of the wire feeding block 69. The wire pressing block 613 presses down through the pressing groove 614, and in conjunction with the fastening rod 617 and the tension spring 616, the wire harness is stably pressed into the wire groove 611.

[0054] Step 3: Activate two electric cylinders 68, one retracting and the other extending. The extending electric cylinder 68 pushes the bottom wire feeding block 69 upward, while the retracting electric cylinder 68 pulls the top wire feeding block 69 downward, triggering the wire feeding blocks 69 to move alternately.

[0055] Step 4: The two wire feeding blocks 69 move along the guide groove 63 via the slide rod 610. First, they move laterally, then enter the inclined groove to achieve upward / downward movement, and then enter the top horizontal groove to move laterally. When the slide rod 610 touches the limiting block 66, it compresses the spring 65. After passing through, the spring 65 returns to its original position, and the limiting block 66 remains aligned with the inclined surface of the guide groove 63.

[0056] 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 lifts up, the torsion spring 615 relaxes, and the wire harness is not pressed tightly for the time being; after moving laterally, the wire pressing block 613 disengages from the release rod 618, the torsion spring 615 resets and drives the wire pressing block 613 to press down, and the wire harness is pressed again through the pressing groove 614.

[0057] Step 6: The bottom wire feeding block 69 feeds the uncrimped wire harness to the crimping seat 41 for crimping. The top wire feeding block 69 brings the crimped wire harness to the bottom, and the crimping block 613 lifts the contact release rod 618, causing the wire harness to loosen. After manual removal, the wire harness is reloaded, completing the cycle feeding.

[0058] 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 within the protection scope of the present invention.

4. The wire harness terminal feeding device according to claim 3, characterized in that, The electric cylinders (68) are staggered, and each set of slide rods (610) has two.

5. A method for feeding wire harness terminals, wherein the wire harness terminal feeding device according to claim 4 is characterized in that, The 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 coincides with the crimping seat (41), and at the same time place the low voltage wire 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). The wire pressing block (613) presses down through the pressing groove (614) and, together with the fastening rod (617), stretches the second spring (616) to stably press the wire harness into the wire groove (611). Step 3: Activate two electric cylinders (68), one retracts and the other extends. The extending electric cylinder (68) pushes the bottom wire feeding block (69) upward, and the retracting electric cylinder (68) pulls the top wire feeding block (69) downward, triggering the wire feeding block (69) to move alternately. Step 4: The two wire feeding blocks (69) move along the guide groove (63) via the slide rod (610). First, they move laterally, then enter the inclined groove to achieve upward / downward movement, and then enter the top horizontal groove to move laterally. When the slide rod (610) touches the limiting block (66), the first spring (65) is compressed. After passing through, the first spring (65) is reset, and the limiting block (66) remains aligned with the inclined surface of the guide groove (63). Step 5: When the bottom wire feeding block (69) moves, the inclined surface of the pressure block (613) against the release rod (618) lifts up, the torsion spring (615) relaxes, and the wire harness is not pressed tightly for the time being; after the lateral movement, the pressure block (613) disengages from the release rod (618), the torsion spring (615) resets and drives the pressure block (613) to press down, and the wire harness is pressed again through the pressure groove (614); Step 6: The bottom wire feeding block (69) feeds the uncrimped wire harness to the crimping seat (41) for crimping. The top wire feeding block (69) brings the crimped wire harness to the bottom. Its crimping block (613) touches the release rod (618) and lifts up, the wire harness is loosened, and it is manually removed and re-fed to complete the cycle feeding.
