With the development of the automotive industry, the requirements for automotive electronics have become increasingly strict. To ensure that each functional component of automotive electronics realizes its function, an automotive wire harness is needed as a bridge to connect various electronic parts of the vehicle, and two wire harnesses need to be butted.

Specific embodiments

[0043] In order to enable those skilled in the art to better understand the solution of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present application.

[0044] The present utility model provides a wire harness welding machine to solve the problems of poor welding quality, low welding efficiency, and inadaptability to batch processing by enterprises when wire harness welding is carried out manually in the prior art.

[0045] For the convenience of understanding, the specific process in the embodiments of the present application will be described below. Please refer to Figures 1 to 6, A wire harness welding machine in an embodiment of the present application includes a machine body 1, and a placement plate 10 for placing a wire harness is provided on one side of the machine body 1; a welding unit 2 is arranged inside the machine body 1, and the welding head end of the welding unit 2 is located on one side of the placement plate 10; a left wire pressing mechanism 3 and a right wire pressing mechanism 4 are oppositely arranged on both sides of the front end of the welding unit 2, and both are located on one side of the placement plate 10; the right pressing mechanism 4 is arranged with adjustable width between it and the left pressing mechanism 3 through a width adjusting mechanism 5; a pressing block 6 is arranged above the left wire pressing mechanism 3 through a transmission mechanism 7, and is used to press the wire harness located between the left wire pressing mechanism 3 and the right wire pressing mechanism 4 down onto the welding unit 2 for welding after moving forward.

[0046] The wire harness welding machine of the present utility model can automatically press the wire harness through the left wire pressing mechanism 3 and the right wire pressing mechanism 4, and then press it down by the pressing block 6 and weld it by the welding unit. The operation is convenient and labor-saving, and the welding accuracy and quality are high, meeting the requirements of batch processing.

[0047] Further, based on Figures 8 to 11 , in this embodiment, the width adjusting mechanism 5 includes a base 51, a transverse moving block 52, a sliding column 53, a sliding seat 54, a reference block 55, a connecting rod 56 and a middle rotating shaft 57; the base 51 is in a square block shape, and a groove is opened on the upper surface of the base 51; the transverse moving block 52 is driven by a driving cylinder 58 to move horizontally in the groove. At the same time, an inclined groove 520 is opened on the upper surface of the transverse moving block 52, and the inclination of the inclined groove 520 is towards the side close to the left wire pressing mechanism 3. The sliding column 53 is vertically and slidably arranged in the inclined groove 520. When the driving cylinder 58 drives the transverse moving block 52 to move forward, the sliding column 53 correspondingly moves obliquely in the inclined groove 520, and its movement trajectory is a horizontally approaching movement relative to the left wire pressing mechanism 3, thereby converting the linear movement of the sliding column 53 into a horizontal movement.

[0048] The sliding seat 54 is installed above the base 51 and is connected to the sliding column 53. In this way, when the sliding column 53 slides in the inclined groove 520 for horizontal movement, the sliding seat 54 synchronously follows the sliding column for horizontal movement.

[0049] The reference block 55 is arranged above the sliding seat 54, and the right wire pressing mechanism 4 is horizontally slidably arranged on the upper surface of the reference block 55. One end of the connecting rod 56 is rotatably arranged on a connecting shaft 59, the connecting shaft 59 is horizontally installed inside the sliding seat 54, and the other end passes through the sliding seat 54 and the reference block 55 and is connected to the right wire pressing mechanism 4; the middle rotating shaft 57 is installed at the middle part of the connecting rod 56, and both ends of the middle rotating shaft 57 are exactly horizontally arranged at both ends of the reference block 55.

[0050] When the sliding seat 54 and the sliding column 53 move laterally, the connecting rod 56 is synchronously driven to rotate with the central shaft 57 as the axis. Specifically, when the sliding seat 54 moves forward, the connecting rod 56 deflects to the left with the central shaft 57 as the axis, thereby driving the right wire pressing mechanism 4 connected to the connecting rod 56 to slide to the left in the reference block. The right wire pressing mechanism 4 and the left wire pressing mechanism 3 cooperate with each other to press the wire harness on the placement plate 10 laterally, which is convenient and labor-saving to operate, and is mechanically driven, and runs stably and reliably.

[0051] Secondly, if the sliding position of the lateral block 52 in the groove is not limited, the lateral block 52 may be separated from the front of the base 51 during lateral movement, so a limiting mechanism 9 is also provided to limit the forward position of the lateral block 52. The limiting mechanism 9 includes a connecting rod 93 vertically connected to the lateral block 52; the connecting rod 93 passes through the base 51 and extends downward to the front end of the blocking block 92; and the blocking block 92 is provided on the screw rod 91; the screw rod 91 drives the blocking block 92 to move horizontally at the front end of the connecting rod 93 via the limiting motor 90.

[0052] During operation, the limit motor 90 starts to work, and the limit motor drives the blocking block 92 to move to the set position in front of the connecting rod 93 through the screw 91. When the transverse block 52 is driven to move forward through the driving cylinder 58, the connecting rod 93 moves synchronously with the transverse block 52. When the connecting rod 93 moves to the set position, the blocking block 92 blocks the connecting rod 93 from continuing to move forward, thereby limiting the forward position of the transverse block 52, preventing the transverse block 52 from sliding directly out of the base 51, and ensuring reliability and stability during operation.

[0053] based on Figure 8 , Figure 10 and Figure 11 In the present embodiment, the transmission mechanism 7 comprises a moving cylinder (not shown in the figure), a lifting cylinder 70, a lifting block 71, a knob 72 and a moving plate 73; the moving cylinder is connected to the pressing block 6 to drive the pressing block 6 to move forward laterally above the left wire pressing mechanism 4; the lifting block 71 is arranged below the left wire pressing mechanism 4, and the lifting block 71 passes through the left wire pressing mechanism 4 and is connected to the moving cylinder, and the bottom of the lifting block 71 is inclined; the lifting cylinder 70 is located at the bottom of the lifting block 71, and the piston rod of the lifting cylinder 70 is connected to the lifting block to lift the lifting block 71 and then synchronously move the pressing block 6 up; the knob 72 is connected to two relatively arranged moving plates 73 to drive the moving plate 73 to move below the lifting block 71, and the moving plate 73 is provided with a positioning inclined surface that fits with the bottom of the lifting block 71.

[0054] During operation, when the left wire pressing mechanism 3 and the right wire pressing mechanism 4 laterally press the wire harness tightly, first, the lifting cylinder 70 lifts the pressing block 6 to the height above the wire harness through the lifting block 71. Then, the pressing block 6 horizontally moves to one side of the right wire pressing mechanism 4 through the moving cylinder. Next, the knob 72 is rotated inward, causing the moving plate 73 to also move forward synchronously to the set position below the lifting block 71. The set position is the welding height of the wire harness. Then, the lifting cylinder 70 stops working, and the piston rod returns to drive the lifting block 71 to move downward. When the bottom of the lifting block 71 fits with the upper surface of the moving plate 73, the welding height of the wire harness is determined at this time. Then, the welding unit 2 welds the wire harness. The height of the welded wire harness is precise, and the operation is convenient and effective.

[0055] Further, based on Figure 3 , the welding unit 2 includes a transducer 20 and a horn 21 installed at the energy output end of the transducer 20; a welding head 22 is fixed to the front end of the horn 21; the welding head 22 is arranged on one side of the placement plate 10, and the entire welding unit 2 is horizontally arranged inside the frame 1, with a compact and practical overall structure.

[0056] Further, based on Figure 3 , Figure 5 and Figure 7 , in this embodiment, the welding unit 2 is arranged in the machine body 1 through the mounting bracket 8. The mounting bracket 8 includes a plurality of semi-circular grooves 80 in a shape imitating the welding unit 2 for placing and fixing the welding unit 2; a heat-conducting silica gel 81 that fits with the welding unit 2 is provided on the semi-circular groove 80; the heat-conducting silica gel 81 is connected to a cooling water channel 82 distributed in the machine body 1; the cooling water channel 82 is distributed along the perimeter of the welding unit 2 and arranged inside the machine body 1, and a speed control valve 83 is provided on the cooling water channel 82 to adjust the flow rate of the cooling water channel.

[0057] During actual operation, the cooling water in the cooling water channel 82 is in a continuous circulating flow. When the welding unit 2 starts to work, the heat generated during the operation of the welding unit 2 can be transferred to the cooling water channel 82 through the heat-conducting silica gel 81, and then the cooling water channel 82 conducts and dissipates the heat, effectively preventing the temperature of the welding unit 2 from being too high and affecting its use, and improving the welding efficiency.

[0058] Secondly, the flow rate of the cooling water channel 82 can be controlled through the speed control valve 83, thereby increasing or decreasing the cooling efficiency to meet the requirements of different occasions.

[0059] In addition, based on Figure 3In this embodiment, the welding unit 2 is also provided with a plurality of temperature detection components 23 for detecting the temperature of the welding unit in the length direction. The temperature detection components 23 are temperature sensors, and are provided in plurality. The plurality of temperature detection components 23 extend their detection heads to the corresponding horn 21 and welding head 22 for provision.

[0060] When the welding unit 2 starts welding, the temperature detection component 23 monitors the temperature of the horn 21 and the welding head 22 in real time, and then sends it to the control system, so as to monitor the temperature of the horn 21 and the welding head 22 in real time. When the monitored temperature is too high, the control system can alarm through the corresponding alarm system; in addition, the control system can also automatically adjust the flow rate of the cooling water circuit 82 through the speed regulating valve 83 to adapt the cooling efficiency of the cooling water circuit 82 at different temperatures, effectively avoiding the temperature of the welding head being too high and causing damage to the welding unit 2, and ensuring the normal use of the welding unit 2.

[0061] based on Figures 1 to 11 The specific usage process is described as follows.

[0062] The wire harness is manually placed on the placement plate 10 so that the wire harness is located between the left wire pressing mechanism 4 and the left wire pressing mechanism 3 .

[0063] At this time, the driving cylinder 58 is turned on, and the driving cylinder 58 drives the transverse block 52 to slide in the base 51, and simultaneously drives the sliding column 53 to move laterally relative to the left wire pressing mechanism 4 during sliding, and the sliding seat 54 follows the sliding column 53. After the sliding seat 54 slides laterally, it drives the connecting rod 56 to tilt toward the left wire pressing mechanism 3, so that the right wire pressing mechanism slides laterally in the reference block 55, and the right wire pressing mechanism 4 and the left wire pressing mechanism 3 approach each other, thereby clamping the wire harness.

[0064] The lifting cylinder 70 lifts the movable cylinder and the pressing block 6 through the lifting block 71, and then the knob 72 is rotated inward to the set position. Then, the pressing block 6 is driven by the movable cylinder to move laterally to above the wire harness that is laterally pressed by the right wire pressing mechanism 4 and the left wire pressing mechanism 3. The lifting cylinder 70 returns to its original position, and the movable plate 73 driven forward by the knob fits under the lifting block, thereby determining the welding height of the wire harness.

[0065] Finally, the welding unit 2 welds the compressed wire harness. During the welding process, the cooling water path 82 dissipates the heat of the welding unit in real time through the thermal conductive silica gel 81, and the temperature of each part of the welding unit 2 is monitored through the temperature detection component 23 to avoid damage caused by excessive temperature.

[0066] After welding is completed, the cylinder 58 and the pressing block are driven back to their original positions, and then the welded wire harness is taken out.

[0067] The wire harness welding machine of the present utility model enables the right wire pressing mechanism and the left wire pressing mechanism to cooperate through a width adjustment mechanism to adapt to wire harnesses of different widths, and meets the welding requirements of wire harnesses of different heights through a transmission mechanism. At the same time, the welding unit can work within a set temperature, with high welding efficiency, long service life of the welding unit, convenient and labor-saving operation, high welding precision, and meeting the batch processing requirements of enterprises.

[0068] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features; and these modifications or replacements do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the present application in each embodiment.
