[0003] The wire harness welding equipment in the prior art heats the wire harness welding part through high-frequency induction heating. The induction coil is circular, and the wire harness is manually placed into the circular induction coil for ultra-high frequency welding. The wire skin is cooled by contact-type semi-wrapped water cooling. Different diameters of wire skin cooling require the replacement of different water-cooling molds. For welding of wire harnesses of different shapes or sizes, the original circular induction coil needs to be disassembled and replaced with a circular induction coil of another size. Due to the large variety of wire harnesses, they need to be replaced frequently, which reduces production efficiency.

[0033] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below 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, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0034] It should be noted that the terms "including" and "having" and any variations thereof in the specification and claims of the present invention and the above-mentioned drawings are intended to cover non-exclusive inclusions. For example, a process, method, apparatus, product or equipment comprising a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or equipment.

[0035] The following is combined with Figure 1-Figure 8 This application is described in further detail.

[0036] refer to Figure 1-Figure 3 An automated soldering device is shown, comprising: a frame 1, on which a welding station, a wire harness fixing mechanism 2, a terminal fixing mechanism 3, an ultra-high frequency welding mechanism and a tin feeding mechanism 4 are arranged; the ultra-high frequency welding mechanism comprises a magnetic induction coil 5 (flat) arranged directly below the welding station; in this way, when in use, the wire harness is fixed by the wire harness fixing mechanism 2, so that the welding end of the wire harness is placed at the welding station, the terminal is fixed by the terminal fixing mechanism 3, so that the welding of the terminal is placed at the welding station, and the tin wire is transported to the welding station by the tin feeding mechanism 4 to feed the ultra-high frequency welding mechanism, and welding is performed by the magnetic induction coil 5 placed directly below the connection between the wire harness and the terminal. Since the magnetic induction coil 5 is placed directly below the welding station, when welding wire harnesses of different specifications, since there is no need to extend the wire harness into the interior of the magnetic induction coil 5, there is no need to replace the magnetic induction coil 5, and welding of different wire harnesses can be used, which has strong adaptability and improves welding efficiency.

[0037] like Figure 3 and Figure 4 As shown, in order to achieve the fixation of the wire harness, the wire harness fixing mechanism 2 includes a first mounting seat 21 arranged on the frame 1, two clamping blocks 22 slidably arranged on the first mounting seat 21, and a first driving member for driving the two clamping blocks 22 to move toward or away from each other. The first mounting seat 21 is arranged on one side of the welding station. In this way, when in use, the wire harness is placed between the two clamping blocks 22, and the two clamping blocks 22 are driven by the first driving member to move toward each other, so that the wire harness is clamped and the welding end of the wire harness is placed at the welding station. The clamping block 22 is placed on the first mounting seat 21 with a quick-release structure. When the clamping block 22 needs to be replaced, it can be achieved quickly and conveniently.

[0038] like Figure 3 and Figure 4 As shown, in order to achieve the fixation of the terminal, the terminal fixing mechanism 3 includes a second mounting seat 31, a clamping plate 32 rotatably arranged on the second mounting seat 31, and a second driving member. The second mounting seat 31 is arranged on the side of the welding station away from the first mounting seat 21. The top surface of the second mounting seat 31 is the terminal placement position. A pressure head 33 is arranged on the side of the top end of the clamping plate 32 close to the terminal placement position. The second driving member is used to drive the clamping plate 32 to rotate in the vertical direction so that the pressure head 33 is close to or away from the terminal placement position. In this way, during processing, the terminal is placed on the positioning pin at the terminal placement position, and then the second driving member drives the clamping plate 32 to rotate, so that the pressure head 33 moves toward the terminal placement position, and finally presses on the terminal to complete the fixation of the terminal.

[0039] like Figure 1 , Figure 5 and Figure 6 As shown, the tin feeding mechanism 4 includes a tin coil assembly 41, a guide tube 42 and a driving mechanism arranged on the frame 1. The tin coil assembly 41 is used to fix the tin coil. The tin wire from the tin coil assembly 41 is inserted into the guide tube 42. The wire outlet of the guide tube 42 is arranged at the bottom. The driving mechanism is used to drive the guide tube 42 to move above the welding station. In this way, the tin coil is placed on the rotating shaft of the tin coil assembly 41, and the tin wire is inserted into the guide tube 42. During welding, the bottom wire outlet of the guide tube 42 is moved to the welding station through the driving mechanism to supply wire for the welding of the ultra-high frequency welding mechanism. In addition, the tin coil assembly 41 also includes two sensors, which respectively sense the head and tail of the solder coil. If the tin coil is used to the end and exposed during the welding process, When the base color of the tin coil skeleton changes, the sensor can sense it, thereby prompting the worker to replace the tin coil to avoid the failure of wire harness welding and scrapping due to insufficient solder tail material; the driving mechanism specifically includes a horizontal linear module 43 and a vibration displacement cylinder 44, the horizontal linear module 43 is arranged on the frame 1, the vibration displacement cylinder 44 is arranged on the horizontal linear module 43, and the guide tube 42 is arranged at the output end of the vibration displacement cylinder 44. The guide tube 42 is driven by the horizontal linear module 43 to move above the welding station to complete the feeding, and the vibration displacement cylinder 44 is used to drive the guide tube 42 to move when supplying tin during welding, so that the feeding is more accurate. When welding thick wire harnesses, the tin water can fill the terminal port more easily, and the welding is completed more efficiently.

[0040] like Figure 2 and Figure 7 As shown, the frame 1 is provided with pneumatic scissors 6 and a waste box arranged below the pneumatic scissors 6 for cutting the tin wire.

[0041] like Figure 1 and Figure 8As shown, one side of the rack 1 is provided with two parallel wire harness fixing plates 7 and a cooling fan arranged below the wire harness fixing plates 7. The wire harness fixing plates 7 are provided with a plurality of wire harness fixing grooves 71, so that the crimped wire harness after welding can be put into the wire harness fixing grooves 71 and cooled by the cooling fan. In addition, an overcooling gas generator is provided on the rack 1 to cool the crimped wire harness during welding and to cool the insulation skin by wrapping. The cooling speed is fast, which can effectively prevent the insulation skin from being damaged by overheating, and can also control the degree of solder infiltration in the wire.

[0042] like Figure 2 As shown, a visual camera 8 is arranged on the frame 1, and the lens of the visual camera 8 faces the welding station. By setting the visual camera 8, the welding quality of the welding part can be detected, and an infrared temperature sensor 9 is arranged on the frame 1. The infrared temperature sensor 9 senses the welding heating part, and the heating temperature and heating time are accurately controlled by the control algorithm.

[0043] Further optimization is that Figure 1 As shown, the frame 1 is also provided with a safety cover 12 at the place where the harness is placed to prevent fingers from being pinched and to prevent the equipment from being triggered by mistake. The safety cover 12 adopts a slot-type design and can be quickly disassembled and replaced without screwing. Sensors and strong magnets are arranged inside the safety cover 12. When the safety cover is removed, the sensor senses a signal and puts the machine in a shutdown state. After the safety cover 12 is installed, the sensor is triggered and the machine can enter the use state. The safety cover is attracted by a strong internal magnet, which effectively prevents the safety cover from being disengaged due to accidental touches and slight impacts, further improving the safety of the equipment.

[0044] Further optimization is that Figure 1 As shown, a welding box is provided on the frame 1, and the corresponding components of the welding harness are placed in the box to avoid external interference with the welding, and the material is put in and out through a working door 11 provided on one side of the box.

[0045] The working principle of the present invention is as follows: an ultra-high frequency welding mechanism is used to perform induction heating on the wiring harness parts that need to be welded. The magnetic induction coil is flat in shape, and the crimped wiring harness is manually placed on the wiring harness fixing mechanism and the terminal fixing mechanism on the frame; after the working button is started, the equipment places the part of the crimped wiring harness that needs to be welded on the flat coil (welding station), and the visual inspection camera is first used to detect whether the compressed wiring harness is matched and placed accurately. After all are judged to be OK, the wiring harness is induction heated, and the infrared temperature sensor senses the welding heating part, and the control algorithm is used to accurately control the heating temperature and heating time; when the set heating temperature is reached, the tin feeding mechanism will feed the tin wire into the welding point for welding, and the supercooled gas generator will cool the crimped wiring harness after the set welding requirements are met; the welding quality of the welding part is visually inspected, and the working door 11 is opened to send out the crimped wiring harness that has been welded, and finally the wiring harness is placed in the wiring harness fixing plate, and the residual heat is removed by the cooling fan.

[0046] The above are only preferred embodiments of the present application, and the present invention is not limited to the above embodiments. It is understood that other improvements and changes directly derived or associated by those skilled in the art without departing from the spirit and concept of the present invention should be considered to be included in the protection scope of the present invention.
