Description

Technical Field

[0001] This application relates to the field of wire harness technology, and in particular to an automatic wire harness cutting and ultrasonic welding processing device. Background Technology

[0002] In the production and processing of automotive wiring harnesses, ultrasonic welding is required to connect and fix two sets of wires. During this process, the two sets of wires need to be butt-joined before ultrasonic welding. Currently, manual butt-joining is mainly used. This involves manually stripping the insulation and crimping the terminals of multiple wires in each set before manually butt-joining the ends of the two sets of wires at the ultrasonic welding station. However, in practical use, this manual butt-joining method is found to be inefficient, affecting the overall welding efficiency of the wiring harness. Furthermore, the butt-joining quality depends heavily on the operator's skill level, which directly impacts the overall welding quality of the wiring harness, ultimately leading to compromised welding quality.

[0053] In one embodiment, such as Figure 1 and Figure 2 As shown in the illustration, this application provides an automatic wire harness cutting and ultrasonic welding processing device 1. Specifically, the device 1 may include multiple first wire processing mechanisms 11, multiple second wire processing mechanisms 12, a first wire paralleling and conveying mechanism 13, a second wire paralleling and conveying mechanism 14, and an ultrasonic welding mechanism 15. The first wire processing mechanisms 11 are mainly used to sequentially cut, strip the front end, crimp terminals, and strip the rear end of automatically fed wires to obtain first wires. The first wire paralleling and conveying mechanism 13 is mainly used to parallelize the multiple first wires obtained by the multiple first wire processing mechanisms 11 to obtain a first set of wires, and then convey the first set of wires to a first position of the ultrasonic welding mechanism 15. The second wire processing mechanisms 12 are mainly used to sequentially cut, strip the front end, crimp terminals, and strip the rear end of automatically fed wires to obtain second wires. The second wire paralleling and conveying mechanism 14 is mainly used to parallelize the multiple second wires obtained by the multiple second wire processing mechanisms 12 to obtain a second set of wires, and then convey the second set of wires to a second position of the ultrasonic welding mechanism 15. The ultrasonic welding mechanism 15 is mainly used to perform ultrasonic welding on the connection point after the first set of wires in the first position and the second set of wires in the second position are connected, so that the first set of wires and the second set of wires are welded together.

[0054] It is understood that the automatic wire cutting ultrasonic welding processing device 1 of this application embodiment is specifically applied to the welding operation between two sets of wires in a wire harness product to produce the corresponding wire harness product. Generally speaking, the number of wires in each set of wires (i.e., the first set of wires or the second set of wires) can be arbitrarily increased or decreased according to the actual needs of the wire harness product being produced. In this case, it is only necessary to adjust the number of the first wire processing mechanism 11 and the second wire processing mechanism 12 accordingly. That is, in the automatic wire cutting ultrasonic welding processing device 1 of this application embodiment, the number of the first wire processing mechanism 11 and the second wire processing mechanism 12 includes, but is not limited to, those of the following: Figure 1The two shown are examples. The first or second conductor mentioned above has a similar structure, both consisting of a stripped front end with a crimped terminal and a stripped rear end. Since the first and second conductors are connected by stacking their rear ends together, stripping the rear ends of both sets of conductors further ensures a good connection. Furthermore, the ultrasonic welding mechanism 15 mentioned above is a standard commercially available ultrasonic welding device and will not be described in detail here.

[0055] In this way, the automatic wire cutting and ultrasonic welding processing device 1 for wire harnesses provided in this embodiment can automatically cut, strip the front end, crimp the terminals, and strip the rear end of automatically fed wires in sequence under the cooperation of multiple first wire processing mechanisms 11, multiple second wire processing mechanisms 12, a first wire paralleling and conveying mechanism 13, a second wire paralleling and conveying mechanism 14, and an ultrasonic welding mechanism 15, respectively, to obtain multiple first wires and multiple second wires. Then, it automatically performs paralleling processing on the multiple first wires and multiple second wires to obtain a first set of wires and a second set of wires. The first set of wires and the second set of wires are then automatically conveyed to the first position and the second position of the ultrasonic welding mechanism 15 to complete the automatic docking operation between the first set of wires and the second set of wires. Finally, the ultrasonic welding mechanism 15 completes the welding operation between the two sets of wires in the wire harness product. In this way, the automatic processing, automatic docking, and automatic welding operations of the two sets of wires in the wire harness product can be completed quickly without manual intervention, thereby greatly improving the overall welding efficiency of the wire harness product while ensuring its welding quality.

[0056] In some examples, such as Figure 1 and Figure 2As shown, multiple first wire processing mechanisms 11 are arranged sequentially along the second direction on the first side of the ultrasonic welding mechanism 15, and multiple second wire processing mechanisms 12 are arranged sequentially along the second direction on the second side of the ultrasonic welding mechanism 15. The first side and the second side are two opposite sides of the ultrasonic welding mechanism 15 in the second direction, and the second direction is perpendicular to the first direction. Thus, through the above structural arrangement, a more reasonable spatial layout can be formed, effectively saving the floor space of the automatic wire cutting ultrasonic welding processing device 1. This allows the first wire paralleling and conveying mechanism 13 to better parallelize multiple first wires after each of the multiple first wire processing mechanisms 11 has processed its corresponding first wire, obtaining a first set of wires and quickly conveying the first set of wires to the first position of the ultrasonic welding mechanism 15. Similarly, the second wire paralleling and conveying mechanism 14 can better parallelize multiple second wires after each of the multiple second wire processing mechanisms 12 has processed its corresponding second wire, obtaining a second set of wires and quickly conveying the second set of wires to the second position of the ultrasonic welding mechanism 15.

[0057] In some examples, such as Figure 1 and Figure 2 As shown, the first wire processing mechanism 11 and the second wire processing mechanism 12 respectively include a wire feeding module 110, a wire feeding module 120, a wire cutting and stripping module 130, and a terminal crimping module 140. The wire feeding module is mainly used for automatic wire feeding operations to convey the wires to the wire feeding module 120. The wire feeding module 120 is mainly used to convey the wires from the wire feeding module back and forth to the wire cutting and stripping module 130 and the terminal crimping module 140. The wire cutting and stripping module 130 is mainly used to cut the wires from the wire feeding module 120 to cut a section of wire with terminals, and to strip the front end of the cut wire and the rear end of the section of wire with terminals to obtain either a first wire or a second wire. The terminal crimping module 140 is mainly used to crimp the front end of the wire fed from the wire feeding module 120, so as to crimp a terminal onto the front end of the wire after the front end has been stripped. In this way, with the above structural configuration, the wire feeding module 110, the wire feeding module 120, the wire cutting and stripping module 130, and the terminal crimping module 140 can work together in sequence to automatically cut, strip the front end, crimp the terminal, and strip the rear end of the automatically fed wire, respectively, to obtain the corresponding first wire or the corresponding second wire.

[0058] In some examples, such as Figure 1 , Figure 2 and Figure 3As shown, the wire feeding module includes a wire storage bin (not shown), a feeding module support 111, a first wire feeding assembly 112, and a second wire feeding assembly 113. The wire storage bin is primarily used to store wires to be fed. The feeding module support 111 may specifically be provided with a first wire guide hole seat 114 and a second wire guide hole seat 115, which are arranged opposite to each other in a first direction. The first wire feeding assembly 112 may be mounted on the feeding module support 111 and located between the first wire guide hole seat 114 and the second wire feeding assembly 113. Its main function is to limit and feed the wire horizontally after it passes through the first wire guide hole seat 114 from the wire storage bin, so that the wire is conveyed along the first direction to the second wire feeding assembly 113. The second wire feeding assembly 113 can be specifically installed on the feeding module bracket 111, and located between the first wire feeding assembly 112 and the second wire passage seat 115. It is mainly used to limit and feed the wires from the first wire feeding assembly 112 in the vertical direction, ensuring the wires are fed along the first direction, pass through the second wire passage seat 115, and reach the wire feeding module 120. Thus, with the above structural arrangement, automatic wire feeding can be achieved through the sequential cooperation of the first and second wire feeding assemblies 112 and 113, ensuring that the wires are fed straight along the first direction to the wire feeding module 120 without any horizontal or vertical deviation during the feeding process. Furthermore, the first wire feeding assembly 112 includes multiple first feeding rollers and a first power structure for driving the multiple first feeding rollers to rotate. The multiple first feeding rollers are respectively installed on the feeding module mounting bracket and are staggered in the horizontal direction to form a first feeding channel extending along the first direction. Thus, with the above structural configuration, the wire can be conveyed straight along the first direction to the second wire feeding assembly 113 via the first wire feeding channel, ensuring that it does not deviate horizontally during the conveying process. Similarly, the second wire feeding assembly 113 includes multiple second wire feeding rollers and a second power structure for driving the multiple second wire feeding rollers to rotate. The multiple second wire feeding rollers are respectively mounted on the loading module mounting bracket and are staggered in the vertical direction to form a second wire feeding channel extending along the first direction. Thus, with the above structural configuration, the wire can be conveyed straight along the first direction to the wire feeding module 120 via the second wire feeding channel, ensuring that it does not deviate vertically during the conveying process.

[0059] It is understood that in this example, both the first wire guide seat 114 and the second wire guide seat 115 have corresponding wire guide holes to facilitate the passage of corresponding wires through the first wire guide seat 114 or the second wire guide seat 115. A wire shortage detection sensor can also be installed at the wire guide hole on the second wire guide seat 115 to detect whether a wire is currently missing by detecting whether a wire is passing through the wire guide hole on the second wire guide seat 115. In this example, the first and second power structures can specifically be conventional motor power structures, driving multiple first wire feeding rollers or multiple second wire feeding rollers to rotate via motor drive, belt drive, or other means.

[0060] In some examples, such as Figure 1 , Figure 2 and Figure 4 As shown, the wire feeding module 120 includes a wire feeding module bracket 121, a wire feeding assembly bracket 122, a third power structure (not shown) for driving the wire feeding module bracket 121 to move back and forth in a second direction, a fourth power structure 123 for driving the wire feeding assembly bracket 122 to move back and forth in a first direction, and a wire feeding assembly 124. The wire feeding assembly bracket 122 is movably mounted on the wire feeding module bracket 121, and is provided with a third wire passage seat 125 and a fourth wire passage seat 126, which are arranged opposite to each other in the first direction. The wire feeding assembly 124 is fixed on the wire feeding assembly bracket 122 and located between the third wire passage seat 125 and the fourth wire passage seat 126. It is mainly used to feed the wire after it has passed through the third wire passage seat 125 from the wire feeding module, so that the wire is fed along the first direction and passes through the fourth wire passage seat 126. Thus, through the above structural configuration, driven by the third power structure, the wire feeding module bracket 121 can sequentially drive the wire feeding assembly bracket 122 and the wire feeding assembly 124 to move back and forth along the second direction, thereby conveying the wire from the wire feeding module to the wire cutting and stripping module 130 and the terminal crimping module 140. Simultaneously, driven by the fourth power structure 123, the wire feeding assembly bracket 122 can drive the wire feeding assembly 124 to move back and forth along the first direction, cooperating with the first stripping cutter assembly 131 mentioned later to complete the aforementioned front-end stripping process. Further, the wire feeding assembly 124 includes multiple wire feeding rollers and a fifth power structure that drives the multiple wire feeding rollers to rotate. The multiple wire feeding rollers are respectively mounted on the wire feeding assembly bracket 122 and staggered in the vertical direction to form a wire feeding channel extending along the first direction. Thus, with the above structural setup, the wire can be transmitted straight along the first direction through the wire delivery channel while ensuring that it does not deviate vertically during transmission.

[0061] It is understood that in this example, both the third wire guide seat 125 and the fourth wire guide seat 126 have corresponding wire guide holes to facilitate the passage of the corresponding wires through the third wire guide seat 125 or the fourth wire guide seat 126. The third and fourth power structures 123 in this example can specifically be conventional motor power structures, driving the wire feeding module bracket 121 to move back and forth in the second direction or driving the wire feeding assembly bracket 122 to move back and forth in the first direction via motor drive, belt drive, or other means. The fifth power structure in this example can specifically be a conventional motor power structure, driving multiple wire feeding rollers to rotate via motor drive, belt drive, or other means.

[0062] In some examples, such as Figure 1 , Figure 2 and Figure 5As shown, the wire cutting and stripping module 130 includes a first stripping blade assembly 131, a cutting blade assembly 132, a second stripping blade assembly 133, a blade power assembly 134, and a wire gripping and moving assembly. The first stripping blade assembly 131, the cutting blade assembly 132, the second stripping blade assembly 133, and the wire gripping and moving assembly are arranged sequentially away from the wire feeding module 120 along a first direction. Specifically, the first stripping blade assembly 131 may include two first stripping blades arranged vertically opposite each other and driven by the blade power assembly 134, so that under the drive of the blade power assembly 134, one first stripping blade moves away from or closer to the other first stripping blade. The cutting blade assembly 132 may specifically include two cutting blades arranged vertically opposite each other and driven by the blade power assembly 134, so that under the drive of the blade power assembly 134, one cutting blade moves away from or closer to the other cutting blade. The second stripping cutter assembly 133 may specifically include two second stripping cutters arranged vertically opposite each other and driven by the cutter power assembly 134, so that under the drive of the cutter power assembly 134, one second stripping cutter moves away from or towards the other second stripping cutter. The wire clamping and moving assembly may specifically include a first wire clamp and a sixth power structure that drives the first wire clamp to move back and forth along a first direction. The first wire clamp is used to clamp a section of wire with a terminal. Thus, with the above structural configuration, the wire conveyed by the wire feeding module 120 can be cut by the action of one cutting cutter of the cutting cutter assembly 132 moving towards the other cutting cutter to cut a section of wire with a terminal. And under the action of one first stripping cutter of the first stripping cutter moving towards the other first stripping cutter, and with the cooperation of the wire feeding assembly bracket 122 driving the wire feeding assembly 124 to move back and forth along the first direction, the front end formed after the wire is cut can be stripped. Furthermore, under the action of the movement of one second stripping blade close to another second stripping blade, and with the cooperation of the wire clamping moving assembly mentioned above, the rear end of a section of wire at the terminal can be stripped to obtain the first wire or the second wire.

[0063] It is understandable that, to achieve the corresponding cutting process, when one cutting tool moves closer to another cutting tool under the drive of the tool power assembly 134, the two cutting tools are ultimately arranged in abutment or staggered arrangement in the vertical direction. Similarly, to achieve the corresponding stripping process, when one first stripping tool (or second stripping tool) moves closer to another first stripping tool (or second stripping tool) under the drive of the tool power assembly 134, the final vertical distance between the two first stripping tools (or two second stripping tools) should be equal to the diameter of the inner core of the wire. The tool power assembly 134 mentioned in this example can specifically be a conventional motor power structure, which drives the tool movable seat to move away from or closer to the tool fixed seat via motor drive, belt drive, or other means. In this example, one first stripping tool, one cutting tool, and one second stripping tool are respectively mounted on the tool movable seat, while another first stripping tool, another cutting tool, and another second stripping tool are respectively mounted on the tool fixed seat. The sixth power structure in this example can be a conventional electric motor power structure, which drives the first wire clamp to move back and forth along the first direction via electric motor drive, belt drive, or other means. The first wire clamp in this example can be a conventional cylinder-driven or electric motor-driven clamp structure.

[0064] In some examples, such as Figure 1 and Figure 2 As shown, the terminal crimping module 140 is equipped with a terminal crimping station. The terminal crimping module 140 includes a terminal storage reel, a step-feed terminal assembly, and a terminal pressing assembly (not shown). The terminal storage reel is mainly used to wind and store terminal strips. The step-feed terminal assembly is mainly used to provide the conveying power for the terminal strip, so that the terminals on the terminal strip pass through the terminal crimping station one by one. The terminal pressing assembly is located above the terminal crimping station and is mainly used to press down the terminal when the wire feeding module 120 conveys the front end of the wire to the terminal at the terminal crimping station, so as to crimp the terminal onto the front end of the wire. In this way, with the cooperation of the step-feed terminal assembly, the terminal pressing assembly, and the wire feeding module 120, the terminal can be automatically crimped onto the front end of the wire after stripping the wire.

[0065] It is understandable that the stepper terminal feeding assembly in this example can be a conventional motor-driven structure, using motor drive, belt drive, and elastic reset to make the pusher block reciprocate near the terminal crimping station, thereby pushing the terminals on the terminal strip one by one through the terminal crimping station. The terminal pressing assembly in this example can also be a conventional motor-driven structure, using motor drive, belt drive, etc., to make the pressing block press down above the terminal crimping station, simultaneously pressing down on the front end of the wire and the corresponding terminal, thereby deforming the terminal, detaching it from the terminal strip, and winding it around the front end of the wire.

[0066] In addition, to ensure the crimping quality of the terminals, the terminal crimping module 140 in this example is specifically equipped with a CCD inspection station. This CCD inspection station is located on one side of the terminal crimping station in the first direction. After the terminal pressing assembly crimps the terminal onto the front end of the wire, the wire feeding module 120 can first convey the corresponding wire from the terminal crimping station to the CCD inspection station for corresponding crimping quality inspection, and then convey the corresponding wire from the CCD inspection station to the wire cutting and stripping module 130. The terminal crimping module 140 also includes a CCD inspection mechanism (not shown in the figure), located above the CCD inspection station. This mechanism uses a CCD camera to detect the terminal crimping quality of the current wire (including the wire stripping length and the appearance of the crimped terminal). When the CCD inspection mechanism detects a defective crimped product, it can, according to actual production needs, either issue an alarm or control subsequent mechanisms to remove the defective product. This application does not impose any limitations on this.

[0067] In some examples, such as Figure 1 and Figure 2As shown, both the first wire paralleling conveying mechanism 13 and the second wire paralleling conveying mechanism 14 are equipped with paralleling stations. The first wire paralleling conveying mechanism 13 and the second wire paralleling conveying mechanism 14 respectively include multiple wire clamping moving modules 210 and wire paralleling moving modules. The multiple wire clamping moving modules 210 are arranged in a one-to-one correspondence with multiple first wire processing mechanisms 11 or multiple second wire processing mechanisms 12. Specifically, the wire clamping moving module 210 may include a second wire gripper and a seventh power structure that drives the second wire gripper to move back and forth along a second direction. The second wire gripper is used to clamp the corresponding first wire or the corresponding second wire, and the wire clamping moving module 210 is used to convey the corresponding first wire or the corresponding second wire to the corresponding paralleling station. The wire paralleling moving module may specifically include a third wire gripper and an eighth power structure that drives the third wire gripper to move back and forth along a second direction. The third wire gripper is used to simultaneously grip the first set of wires after the multiple wire gripping moving modules 210 respectively transmit the corresponding first wires to the corresponding paralleling station and obtain the first set of wires, or to simultaneously grip the second set of wires after the multiple wire gripping moving modules 210 respectively transmit the corresponding second wires to the corresponding paralleling station and obtain the second set of wires. The wire paralleling moving module is used to transmit the first set of wires at the corresponding paralleling station to a first position, or to transmit the second set of wires at the corresponding paralleling station to a second position. Thus, through the above structural configuration, with the cooperation of multiple wire clamping moving modules 210 and wire paralleling moving modules, the multiple first wires obtained by multiple first wire processing mechanisms 11 can be automatically paralleled to obtain a first set of wires, and then the first set of wires can be transmitted to the second position of the ultrasonic welding mechanism 15. Alternatively, the multiple second wires obtained by multiple second wire processing mechanisms 12 can be automatically paralleled to obtain a second set of wires, and then the second set of wires can be transmitted to the second position of the ultrasonic welding mechanism 15.

[0068] It is understood that the seventh power structure in this example can be a conventional motor power structure, driving the second wire clamp to move back and forth along the second direction via motor drive, belt drive, or other means. The second wire clamp in this example can be a conventional cylinder-driven or motor-driven clamp structure. Similarly, the eighth power structure in this example can be a conventional motor power structure, driving the third wire clamp to move back and forth along the second direction via motor drive, belt drive, or other means. The third wire clamp in this example can be a conventional cylinder-driven or motor-driven clamp structure.

Any equivalent structural transformations made based on the inventive concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the patent protection scope of this application.
