Description

Technical Field

[0001] This invention relates to the field of motor coil welding technology, specifically to an automatic motor coil welding device. Background Technology

[0002] In the field of motor manufacturing, the welding quality of motor coils directly affects the performance, reliability, and service life of the motor. With the continuous development of the motor industry, increasingly higher demands are being placed on the efficiency, precision, and quality of motor coil welding. However, during the motor coil welding process, the terminals after wiring are in a suspended state, requiring stable position and posture during welding to ensure accuracy. Current welding methods often involve first mounting the workpiece on a fixture, then inserting a support structure from one side to position it at the bottom of the welding location. After welding, this structure is then disassembled along with the workpiece. This process is cumbersome and inefficient. Furthermore, during prolonged welding, residual solder tends to accumulate on the top of the support structure, altering its flatness and smoothness. Placing terminals on an uneven support structure top leads to unstable terminal position and posture. Therefore, manual cleaning is required during disassembly, increasing material changeover time and impacting production continuity. Summary of the Invention

[0003] The purpose of this invention is to provide an automatic welding device for motor coils to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the present invention provides the following technical solution: an automatic welding device for motor coils, comprising:

[0005] The workbench has a servo electric cylinder that is horizontally moved on top of it. The output end of the servo electric cylinder is equipped with a soldering iron tip, and the end of the servo electric cylinder is equipped with an infrared ranging sensor for detecting the position and wear of the soldering iron tip.

[0006] Multiple mounting platforms are slidably placed on the top of the workbench. Limiting plates are fixed to both sides of the mounting platforms. A support plate for supporting the welding position is provided in the middle of the limiting plate. A linkage part for controlling the lifting and flipping of the support plate is provided on the top of the workbench. Multiple storage slots are opened on the top of the mounting platforms for storing and cleaning the support plates.

[0007] Preferably, a gantry frame is fixedly connected to the outer side of the workbench, a linear module is horizontally fixedly connected to the middle of the gantry frame, the servo electric cylinder is vertically fixedly connected to the moving slide of the linear module, and an exhaust pipe is installed at the end of the servo electric cylinder.

[0008] Preferably, a protective cover is fixedly connected to the end of the housing of the servo electric cylinder, and the infrared ranging sensor is embedded on both sides of the protective cover, with the position of the infrared ranging sensor corresponding to the bottom of the soldering iron tip.

[0009] Preferably, the output end of the servo electric cylinder is fixedly connected to an adjustment frame, the middle part of the adjustment frame is fixedly connected to a threaded rod, and two adjustment sliders are slidably connected to the outer side of the adjustment frame. The adjustment sliders are slidably mounted on the outer side of the threaded rod, and fixing nuts are threadedly connected to the outer side of the threaded rod and on both sides of the adjustment sliders.

[0010] Preferably, a solder nozzle is fixedly attached to one side of the adjusting slider, and solder feeders are fixedly attached to both sides of the servo cylinder. The bottom of the solder feeder is connected to the solder nozzle through a solder guide tube, and a wire feeding frame is installed on one side of the solder feeder.

[0011] Preferably, the worktable has two linear modules II fixedly connected inside, the output end of the linear modules II being fixedly connected to the mounting platform, and the top of the mounting platform having multiple positioning blocks fixedly connected for positioning the workpiece.

[0012] Preferably, the linkage includes a traction groove and a lifting plate. The traction groove is fixed to the top of the workbench and located on both sides of the linear module two. The traction groove has an oblique "Z" shaped structure and is used to drive the lifting plate to move horizontally and rise vertically at the same time.

[0013] Preferably, the limiting plate has multiple lifting grooves in the middle, and a guide groove is fixedly connected inside the lifting groove for driving the support plate to flip to a horizontal state. A limiting roller is rolled inside the guide groove, and a drive arm is rotatably connected to the end of the limiting roller. The other end of the drive arm is obliquely fixed to the outside of the support plate. A lifting plate is rotatably connected to one end of the support plate. The lifting plate is vertically slidably connected to the mounting platform. A rotating column is rotatably connected to one side of the bottom of the mounting platform. The rotating column is rolled in the traction groove.

[0014] Compared with existing technologies, the advantages of this invention are as follows: Two mounting platforms are set up and alternately cooperate with the soldering iron tip. When one mounting platform is performing welding operations, the other can be used for loading and unloading, reducing equipment idle time and improving overall welding efficiency. The linkage unit, through a traction groove, enables the support plate to be vertically inserted into the storage groove during loading and unloading. The top edge of the storage groove scrapes and cleans the outside of the support plate, preventing impurities from accumulating and affecting welding. During welding, it is pulled vertically upwards and flipped to a horizontal state to provide support for the welding part, reducing manual operation and improving production efficiency and welding quality stability. After the support plate is stored, it facilitates workpiece loading and unloading, reducing the difficulty and interference of manual operation. The infrared ranging sensor can detect the position and wear of the soldering iron tip. When the soldering iron tip deviates laterally, the controller activates the alarm to prevent inaccurate welding. When the bottom of the soldering iron tip wears beyond a preset length, the infrared ranging sensor cannot detect the position, the controller activates the alarm and illuminates the indicator light, reminding the user to replace the soldering iron tip and ensuring welding quality.

Detailed Implementation

[0026] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0027] Please see Figures 1-10 This invention provides a technical solution: an automatic welding device for motor coils, comprising: a workbench 1 with a control switch at one end; a servo cylinder 4 horizontally mounted on the top of the workbench 1; a soldering iron tip 12 mounted on the output end of the servo cylinder 4; an infrared ranging sensor 8 mounted on the end of the servo cylinder 4 for detecting the position and wear of the soldering iron tip 12; two mounting platforms 15 slidably mounted on the top of the workbench 1; limit plates 18 fixed to both sides of the mounting platforms 15; a support plate 21 for supporting the welding position mounted in the middle of the limit plates 18; a linkage part for controlling the lifting and tilting of the support plate 21 mounted on the top of the workbench 1; and multiple storage slots 17 on the top of the mounting platforms 15 for storing and cleaning the support plate 21.

[0028] It should be noted that this embodiment is equipped with a PLC controller and corresponding operation buttons. Positioning blocks 16 for positioning workpieces are installed on the top of both mounting platforms 15. The two mounting platforms 15 alternately cooperate with the soldering iron tip 12. When the mounting platform 15 slides to the loading position of the worktable 1, under the action of the linkage, the support plate 21 is vertically inserted downwards into the receiving slot 17. During insertion, the top edge of the receiving slot 17 scrapes and cleans the outside of the mounting platform 15, thereby achieving automatic cleaning of the receiving slot 17 and preventing accumulated impurities from affecting the welding position. The support plate 21 is stored in the receiving slot 17, facilitating the loading and unloading of workpieces. After unloading and reloading, the mounting platform 15 moves forward to the position corresponding to the soldering iron tip 12. During this period, under the action of the linkage, the support plate 21 separates vertically upwards from the receiving slot 17 and rotates to a horizontal state, thus supporting the terminals when the soldering iron tip 12 solders the suspended terminals after wiring.

[0029] In one embodiment, a gantry frame 2 is fixedly connected to the outer side of the workbench 1, a linear module 3 is horizontally fixedly connected to the middle of the gantry frame 2, a servo electric cylinder 4 is vertically fixedly connected to the moving slide of the linear module 3, and an exhaust pipe 27 is installed at the end of the servo electric cylinder 4.

[0030] It should be noted that, in this embodiment, a heating element for heating the soldering iron tip 12 is installed on the top of the soldering iron tip 12, and a temperature controller for controlling the heating temperature is installed on the outside of the gantry 2. The servo cylinder 4 drives the soldering iron tip 12 to move up and down. During this period, the linear module 3 drives the servo cylinder 4 to move laterally, thereby switching the soldering iron tip 12 above the two mounting platforms 15, so as to facilitate the operation on the top of the two mounting platforms 15 respectively. The exhaust pipe 27 is located at the position of the corresponding soldering iron tip 12, and an air purifier is installed at one end of the exhaust pipe 27 to filter the fumes generated by welding.

[0031] In one embodiment, a protective cover 7 is fixedly connected to the end of the housing of the servo electric cylinder 4, and an infrared ranging sensor 8 is embedded on both sides of the protective cover 7, with the infrared ranging sensor 8 corresponding to the position of the bottom of the soldering iron tip 12.

[0032] It should be noted that in this embodiment, the infrared ranging sensor 8 is a reflective infrared ranging sensor. An observation window is installed in the middle of the protective cover 7, and the infrared ranging sensor 8 is installed on both sides of the protective cover 7. When the servo cylinder 4 raises the soldering iron tip 12 into the protective cover 7, and the linear module 3 drives the servo cylinder 4 to move laterally, the infrared ranging sensor 8 measures the position of the bottom of the soldering iron tip 12 to determine whether the lateral position of the soldering iron tip 12 has shifted. When its position changes, the controller controls the alarm to sound, thereby avoiding inaccurate soldering caused by the position deviation of the soldering iron tip 12. Furthermore, when the bottom of the soldering iron tip 12 is worn beyond the preset length, the bottom of the soldering iron tip 12 is above the infrared ranging sensor 8, thus preventing the infrared ranging sensor 8 from detecting the position of the soldering iron tip 12. When its threshold reaches the preset value, the controller controls the alarm to sound and controls the corresponding indicator light to light up, thereby reminding the user to replace the soldering iron tip 12.

[0033] In one embodiment, the output end of the servo cylinder 4 is fixedly connected to an adjustment frame 9, the middle of the adjustment frame 9 is fixedly connected to a threaded rod 10, and two adjustment sliders 11 are slidably connected to the outer side of the adjustment frame 9. The adjustment sliders 11 are slidably installed on the outer side of the threaded rod 10. The outer side of the threaded rod 10 and the two sides of the adjustment sliders 11 are threadedly connected to fixing nuts. A solder nozzle 13 is obliquely fixed to one side of the adjustment slider 11. Solder feeders 5 are fixedly connected to both sides of the servo cylinder 4. A solder breaker is installed at the bottom of the solder feeder. The bottom of the solder feeder 5 is connected to the solder nozzle 13 through a solder guide tube. A wire feeding frame 6 is installed on one side of the solder feeder 5.

[0034] It should be noted that, in this embodiment, when adjusting the position of the soldering iron tip 12, the fixed thread positions on both sides of the adjusting slider 11 are adjusted, and the adjusting slider 11 is slid on the guide rail outside the adjusting frame 9. When the position reaches the desired position, the self-locking nuts on both sides of the adjusting slider 11 are tightened, so that the two nuts press and fix the adjusting slider 11, thereby adjusting the position of the soldering iron tip 12. During operation, the solder bar reel is placed on the outside of the wire feeding frame 6, and the solder bar passes through the middle of the conveying wheel in the middle of the solder feeder 5 and then through the middle of the solder breaker below, so that it enters the solder outlet nozzle 13 along the solder guide tube. The extension length of the solder bar in the solder outlet nozzle 13 is adjusted by the conveying of the solder feeder 5, so that the solder bar and the soldering iron tip 12 cooperate to achieve soldering.

[0035] In one embodiment, two linear modules 14 are fixedly connected inside the workbench 1. The output end of the linear module 14 is fixedly connected to the mounting platform 15. Multiple positioning blocks 16 are fixedly connected to the top of the mounting platform 15 for positioning the workpiece.

[0036] It should be noted that, in this embodiment, the top of the workbench 1 has two sliding grooves that correspond to the linear module 14. An n-shaped plate is fixedly connected to the top of the workbench 1 and the top of the sliding groove. A sliding sleeve is slidably connected to the outside of the n-shaped plate. The top of the sliding sleeve is fixedly connected to the bottom of the mounting platform 15. The bottom of the sliding sleeve passes through the sliding groove and is fixedly connected to the movable slide of the linear module 14. The two linear modules 14 drive the mounting platform 15 to work alternately with the soldering iron tip 12.

[0037] In one embodiment, the linkage includes a traction groove 23 and a lifting plate 22. The traction groove 23 is fixedly connected to the top of the workbench 1 and located on both sides of the linear module 14. The traction groove 23 has an oblique "Z" shaped structure and is used to drive the lifting plate 22 to move horizontally and rise simultaneously. A plurality of lifting grooves 19 are provided in the middle of the limiting plate 18. A guide groove 20 is fixedly connected inside the lifting groove 19 and is used to drive the support plate 21 to flip to a horizontal state. A limiting roller 26 is rotatably connected inside the guide groove 20. A drive arm 25 is rotatably connected to the end of the limiting roller 26. The other end of the drive arm 25 is obliquely fixed to the outside of the support plate 21. The lifting plate 22 is rotatably connected to one end of the support plate 21. The lifting plate 22 is vertically slidably connected to the mounting platform 15. A rotating column 24 is rotatably connected to one side of the bottom of the mounting platform 15. The rotating column 24 is rotatably installed in the traction groove 23.

[0038] It should be noted that in this embodiment, the traction groove 23 is divided into a lower horizontal section, an inclined section, and an upper horizontal section. When the linear module 214 drives the mounting platform 15 to be in the lower horizontal section, the lower horizontal section uses the rotating column 24 to make the top of the lifting plate 22 be at the lowest level and flush with the top of the storage groove 17. At this time, the drive arm 25 and the limiting roller 26 at the end of the support plate 21 are in a vertical state under the guidance of the guide groove 20 and are inserted into the storage groove 17. The edge corner of the storage groove 17 scrapes the outside of the storage groove 17. After the material is taken out, the mounting platform 15 can be cleaned by blowing air. When the linear module 214 drives the rotating column 24 into the inclined section, the inclined surface of the traction groove 23 drives the lifting plate 22 to move vertically upward. The lifting plate 22 drives the support plate 21 to be pulled upward from the inside of the storage groove 17. After the support plate 21 is pulled out, it moves vertically upward. At this time, the drive arm 25 moves vertically upward along the guide groove 20. The lifting plate 22 drives the support plate 21 to move vertically upward. During the vertical lifting process, when the limiting roller 26 slides into the horizontal guide groove 20, the end of the support plate 21 rotates outside the lifting plate 22 under the action of the lever, so that the support plate 21 is in a horizontal state. At this time, the limiting roller 26 enters the upper horizontal section of the traction groove 23. At this time, the soldering iron tip 12 corresponds to the mounting table 15. When the soldering iron tip 12 and the mounting table 15 are in cooperation, the height of the lifting plate 22 is constant, so that the support plate 21 can provide support for the welding part of the workpiece. After the welding is completed, the linear module 2 14 drives the mounting table 15 to reset, so that the support plate 21 rotates downward and is vertically inserted into the receiving groove 17, so that it is cleaned while being stored. At this time, when the rotating column 24 enters the lower horizontal section, the position of the lifting plate 22 is constant, so that the support plate 21 is always in the receiving groove 17. This cycle is repeated to achieve that the support plate 21 is in a horizontal state during welding and the support plate 21 is inserted into the receiving groove 17 when loading and unloading.
