Description

Technical Field

[0001] The present invention relates to the technical field of automobile wire harness processing, in particular to an automobile wire harness terminal crimping device and an operating method thereof. Background Art

[0002] The automotive wiring harness is the network backbone of the vehicle's electrical circuits. Without it, there would be no automotive circuits. A wiring harness is a component that connects wires and cables to contacts (connectors) punched from copper, then crimped with plastic-molded insulators or metal housings to form a bundled circuit.

[0003] During the production of automotive wiring harnesses, the raw material cables are cut according to specifications. The ends of the cut cables are peeled to expose the internal metal wires. Then, in order to connect and integrate all the cables with the plastic parts, the cable ends are crimped with the metal terminals first, and then the terminals are plugged with the plastic parts to realize the composition of a whole wiring harness. The most common crimping operation is that workers manually feed the cables into the crimping device, insert the cables into the terminals manually, and then control the machine to crimp. After crimping, the cables are manually retrieved, and the cycle repeats. Only one cable can be crimped at a time, and workers need to manually insert the cables into the terminals each time. If the workers are not very skilled in the early stage, the crimping efficiency will be very low. Even if the workers are familiar with the operation in the later stage, such ordinary manual plugging will be very tiring, and each manual plugging and taking out of the material will cause a gap in the middle of the machine, thereby reducing work efficiency to a certain extent.

The first strip hole 23 is arranged opposite the first transmission belt 19. The crimping assembly 9 is connected to the first transmission belt 19 on the side facing the first transmission belt 19. When the first motor 14 is started, the first motor 14 can drive the first transmission belt 19 to move through the first driving pulley 15 and the first driven pulley 18, and the movement of the first transmission belt 19 can drive the crimping assembly 9 to move along the length direction of the first slide rail 8.

[0052] In order to enable the crimping assembly 9 to move along the length direction of the first slide rail 8 while also being able to crimp the terminals on the conveyor belt 5, in this embodiment, the top of the limit plate 10 is fixedly mounted on the vertical plate 7 by an assembly bracket 20, and the bottom of the limit plate 10 is integrally provided with a plurality of protrusions 21, which connect the bottom of the limit plate 10 into an undulating shape, and the bottom end surface of the limit plate 10 is also provided with a guide groove 22 arranged along the connection direction of the protrusions 21, and the top of the crimping assembly 9 is tightly abutted in the guide groove 22. When the crimping assembly 9 is moved by the first transmission belt 19, the top of the crimping assembly 9 can move up and down along the undulating shape formed by the protrusions 21 at the bottom of the limit plate 10, and each movement of the crimping assembly 9 toward the conveyor belt 5 can realize the crimping of the terminals on the conveyor belt 5, and when the feeding mechanism 6 transports the end of the wire harness to the inside of the terminal on the conveyor belt 5, the crimping of the crimping assembly 9 can realize the sequential crimping of multiple wire harnesses.

[0053] See also Figure 5-10 , in order to enable the crimping assembly 9 to move along the first slide rail 8 and to cooperate with the bottom of the limiting plate 10 to realize the crimping of the terminal, in this embodiment, the crimping assembly 9 includes a shell 24, and the outer cover of the shell 24 on the side away from the vertical plate 7 is provided with a cover plate 25, and the interior of the shell 24 is fixedly installed with a second slide rail 26 arranged along its length direction. The interior of the shell 24 is also provided with a crimping seat 27, and a second slide seat 30 is fixedly installed on the outer wall of the crimping seat 27 on the side facing the second slide rail 26. The second slide seat 30 is slidably arranged on the second slide rail 26, and the side of the crimping seat 27 away from the second slide rail 26 is provided with an assembly groove arranged along its length direction (not shown in the figure), and an assembly block 28 and The crimping head 29 is arranged below the assembly block 28.

[0054] When the first transmission belt 19 moves, the first transmission belt 19 can pull the connecting plate 42 to move synchronously through the connecting groove 43, and the connecting plate 42 then drives the shell 24 to move synchronously. At this time, the crimping seat 27 inside the shell 24 will also move synchronously with the shell 24. At the same time, the vertical rod 31 on the top of the crimping seat 27 will squeeze the crimping seat 27 downward through the interaction of the guide roller 33 and the guide groove 22, and the crimping seat 27 will move toward the conveyor belt 5 along the second slide rail 26 through the second slide seat 30. When the crimping head 29 installed on the crimping seat 27 contacts the terminal, a crimping operation is realized. According to the number of protrusions 21 at the bottom of the limit plate 10 rolled by the guide roller 33, the crimping operation of the same number of wire harness end terminals can be realized.

[0055] In order to enable the crimping seat 27 to drive the crimping head 29 to move and automatically reset after crimping, in this embodiment, a top plate 34 is fixedly mounted on the top end of the housing 24. The top plate 34 has a through hole 36 for the vertical rod 31 to pass through. A spring 35 is also sleeved on the outside of the vertical rod 31 and is arranged between the top plate 34 and the top seat 32.

[0057] Through the above-mentioned scheme of the present invention, the present invention sets a limit plate 10, and sets a protrusion 21 integrally at the bottom of the limit plate 10, all protrusions 21 form an undulating shape, when the crimping assembly 9 moves along the first slide rail 8, the protrusion 21 can squeeze the crimping seat 27 through the guide roller 33, and when the crimping seat 27 drives the crimping head 29 toward the conveyor belt 5, the crimping of the terminal can be achieved, and according to the number of protrusions 21, the crimping of the same number of wire harness end terminals can be achieved, and after each crimping, the spring 35 will drive the top seat 32 and the guide roller 33 to automatically reset, so when the feeding mechanism 6 is continuously reset toward the conveyor belt 5, uninterrupted crimping of the wire harness end terminals can be achieved.

[0058] Example 2: Please refer to Figure 11-18, for Example 1, in order to enable the feeding mechanism 6 to better feed the wire toward the conveyor belt 5, in this embodiment, the feeding mechanism 6 includes a bottom plate 44 fixedly mounted on the top of the base 1, and a support plate 45 is symmetrically mounted on the top of the bottom plate 44 along the center, and a cross plate 46 is fixedly mounted on the top end of the support plate 45, and a third slide rail 47 arranged along its length direction is symmetrically mounted on the top of the cross plate 46 along the center. The third slide rail 47 is perpendicular to the conveyor belt 5, and a feeding assembly 48 is slidably mounted on the third slide rail 47. The cross plate 46 also has a second strip hole 49 symmetrically opened along the center. The second strip hole 49 is arranged along the length direction of the third slide rail 47, and the second strip hole 49 is arranged Between the two third slide rails 47, a second motor 51 is fixedly installed on the side of the bottom of the cross plate 46 away from the conveyor belt 5, and a second driving pulley 52 is fixedly installed on the end of the output shaft of the second motor 51. A second assembly shaft 53 is installed on the side of the bottom of the cross plate 46 close to the conveyor belt 5, and a second driven pulley 54 is rotatably installed on the bottom end of the second assembly shaft 53. The second driving pulley 52 and the second driven pulley 54 are connected to each other through a second transmission belt 55. The feeding assembly 48 passes through the second strip hole 49 toward the side of the second strip hole 49 and is fixedly connected to the second transmission belt 55, and the two feeding assemblies 48 are respectively connected on opposite sides of the second transmission belt 55.

[0059] By starting the second motor 51, the second motor 51 can drive the second transmission belt 55 to move through the second active pulley 52 and the second driven pulley 54, and when the second transmission belt 55 moves, it can respectively drive the two feeding assemblies 48 to move, and because the two feeding assemblies 48 are respectively connected to the opposite sides of the second transmission belt 55, when the feeding assembly 48 on one side moves toward the conveyor belt 5, the feeding assembly 48 on the other side will move away from the conveyor belt 5. In actual use, when one of the feeding assemblies 48 sends the wiring harness to the conveyor belt 5 and completes the crimping, it can return and make the feeding assembly 48 on the other side drive the wiring harness to move toward the conveyor belt 5, so that reciprocating feeding can be realized, and the crimped wiring harness can be removed from the feeding assembly 48 while the crimping assembly 9 is crimping, and the next loading can be carried out at the same time, which also indirectly saves the downtime during material changing and unloading.

[0060] In order to prevent the two feeding assemblies 48 from colliding with each other when they move back and forth along the third slide rail 47, in this embodiment, the feeding assembly 48 includes a moving block 56, a third slide 57 is fixedly installed on the bottom of the moving block 56, and the third slide 57 is slidably installed on the third slide rail 47. A hanging plate 58 is fixedly installed on one side wall of the moving block 56 facing the center of the cross plate 46, and the bottom of the hanging plate 58 is arranged through the second strip hole 49, and a clamping plate 59 is also installed on the side wall of the hanging plate 58 away from the moving block 56. The second transmission belt 55 is arranged between the hanging plate 58 and the clamping plate 59, and the top of the moving block 56 is fixedly installed with a fourth slide rail 60. The fourth slide rail 60 is perpendicular to the third slide rail 47, and the top of the moving block 56 is also provided with a feeding The material block 62, the bottom of the feeding block 62 is fixedly installed with a fourth slide 65, and the fourth slide 65 is slidably installed on the fourth slide rail 60. The feeding block 62 is integrally provided with a feeding rod 63 on the side facing the conveyor belt 5, and the top of the feeding rod 63 away from the feeding block 62 is fixedly installed with a wire clamp 64. The moving block 56 is provided with a notch groove 61 at the end away from the lifting plate 58. The bottom of the feeding block 62 is fixedly installed with a vertical shaft 66 at one end close to the notch groove 61, and the bottom end of the vertical shaft 66 is rotatably installed with a guide wheel 67. The cross plate 46 also has a guide hole 50 symmetrically provided along the center. The guide hole 50 is arranged as a whole along the length direction of the cross plate 46, and the middle part of the guide hole 50 is arranged away from the center of the cross plate 46, and the guide wheel 67 is rollingly arranged in the guide hole 50.

[0061] When the moving block 56 moves along the third slide rail 47, the vertical shaft 66 will also drive the guide wheel 67 to roll in the guide hole 50. When the moving block 56 moves to the center position of the guide hole 50 away from the center of the horizontal plate 46, the vertical shaft 66 guide wheel 67 will pull the vertical shaft 66 away from the center setting of the horizontal plate 46 through the guide hole 50. At this time, the vertical shaft 66 will drive the feeding block 62 to move along the fourth slide rail 60, and then the feeding block 62 will drive the clamp 64 away from the center setting of the horizontal plate 46 through the feeding rod 63. When the moving blocks 56 on both sides move synchronously, the clamps 64 on both sides will move away from each other to avoid collision between them, and also make the loading position and the taking position of the two clamps 64 in the same position.

[0062] In order to enable the wire clamp 64 to effectively fix the wire harness and prevent it from loosening during feeding, in this embodiment, the wire clamp 64 includes a strip plate 68 fixedly mounted on the end of the feeding rod 63. The strip plate 68 is parallel to the conveyor belt 5. A pressure plate 69 is provided on the top of the strip plate 68, and a relatively arranged wire clamping groove 70 is opened on a section of the surface of the strip plate 68 opposite to the pressure plate 69. The wire harness with the peeled end is placed into the wire clamping groove 70, so that the wire harness can be positioned to a certain extent. One end of the strip plate 68 is hinged to the pressure plate 69, and the other end of the strip plate 68 and the pressure plate 69 are connected by a fastener 71. The function of the fastener 71 here is to limit the end of the strip plate 68 and the pressure plate 69 to prevent the wire harness in the wire clamping groove 70 from loosening. Any component that can play a fixing role, such as a buckle or magic tape, can be used, and no further details will be given here.

[0063] Through the above-mentioned scheme of the present invention, the feeding assembly 48 provided in the present invention can be reciprocated by the second transmission belt 55, and the two feeding assemblies 48 can realize alternating loading with each other. When the feeding assembly 48 on one side is loading, the feeding assembly 48 on the other side can realize unloading and preparing materials. Such alternating reciprocating movement can realize the most efficient crimping of the wire harness end terminals, and the setting of the wire clamp 64 can be practically coordinated with the crimping assembly 9, and multiple wire harness end terminals can be crimped at one time, thereby improving work efficiency.

[0064] Example 3: For Example 1 and Example 2, in order to better reflect the use effect of the above-mentioned automobile wiring harness terminal crimping device, this embodiment provides an operating method of the above-mentioned automobile wiring harness terminal crimping device, which mainly includes the following steps:

[0065] S1, clamping and positioning the wiring harness by the wire clamp 64;

[0066] S2, start the second motor 51, and adjust and move one of the wire clamps 64 toward the conveyor belt 5 until the end of the wire harness is inserted into the terminal on the conveyor belt 5;

[0067] S3, start the first motor 14, adjust the position of the crimping assembly 9, until the crimping head 29 completes crimping on the terminal inserted into the wiring harness;

[0068] S4. Start the second motor 51 in reverse, adjust the wire clamp 64 in S2 to the initial position, and adjust the conveyor belt 5 at the same time, move the crimped terminal to just below the limit plate 10, and move the wire harness end in the other wire clamp 64 to insert it into the terminal;

[0069] S5, start the first motor 14 in reverse until the crimping assembly 9 returns to the initial position in S3;

[0070] S6. Execute the steps from S1 to S5 in sequence.

[0071] Through the above scheme of the present invention, it can be seen that the entire working process can realize reciprocating cycle crimping, and compared with the traditional workers holding the wire harness and plugging the terminals one by one, and then starting the crimping by controlling the crimping device, this operation method can realize the preparation of multiple wire harnesses in the early stage and quickly realize the rapid crimping of multiple wire harnesses. At the same time as the multiple wire harnesses are crimped, the uncrimped wire harnesses can be prepared by another wire clamp 64, which saves the downtime of the crimping assembly 9 and improves work efficiency.

[0072] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in actual process is described in detail below.

[0073] The present invention is provided with a limit plate 10, and a protrusion 21 is integrally provided at the bottom of the limit plate 10. All the protrusions 21 form an undulating shape. When the crimping assembly 9 moves along the first slide rail 8, the protrusion 21 can squeeze the crimping seat 27 through the guide roller 33. When the crimping seat 27 drives the crimping head 29 toward the conveyor belt 5, the terminal can be crimped. Moreover, according to the number of protrusions 21, the same number of wire harness end terminals can be crimped. After each crimping, the spring 35 will drive the top seat 32 and the guide roller 33 to automatically reset. Therefore, when the feeding mechanism 6 is continuously reset toward the conveyor belt 5, uninterrupted crimping of the wire harness end terminals can be achieved.

[0074] The feeding assembly 48 provided in the present invention can be moved back and forth through the second transmission belt 55, and the two feeding assemblies 48 can realize alternating loading with each other. When the feeding assembly 48 on one side is loading, the feeding assembly 48 on the other side can realize unloading and preparing materials. Such alternating reciprocating movement can realize the most efficient crimping of the wire harness end terminals, and the setting of the wire clamp 64 can be practically coordinated with the crimping assembly 9, and multiple wire harness end terminals can be crimped at one time, thereby improving work efficiency.

[0075] Moreover, through the operating method described in the present invention, it can be seen that the entire working process can realize reciprocating cycle crimping, and compared with the traditional workers holding the wire harness and plugging the terminals one by one, and then starting the crimping by controlling the crimping device, this operating method can be combined with the provided crimping device to realize the preparation of multiple wire harnesses in the early stage, and quickly realize the rapid crimping of multiple wire harnesses. At the same time as multiple wire harnesses are crimped, another wire clamp 64 can be used to prepare the uncrimped wire harnesses, thus saving the downtime of the crimping assembly 9 and improving work efficiency.
