Description

Technical Field

[0001] The present invention relates to the field of motor stator production, and particularly to a fully automatic wire winding and tin dipping device. Background Art

[0002] In recent years, with the gradual expansion of the demand for motors, the existing motor production mode is difficult to meet the market demand. As an important part of the motor, the production efficiency and quality of the stator directly affect the production and use of the motor.

[0003] For the existing stator, from feeding to wire winding and then to tin dipping, there is no complete set of production process. Each process is independently completed and cannot be interconnected. The equipment for completing each process is diverse, resulting in uneven quality of the manufactured products. Even the completion of each part of the stator process is not carried out in the same enterprise. When the production is completed, it is necessary to transfer between multiple companies, and the automatic production of the stator core cannot be realized, resulting in extremely low production efficiency of the stator core and inability to meet the market demand. Summary of the Invention

[0004] In order to solve the above problems, the primary object of the present invention is to provide a fully automatic wire winding and tin dipping device, which combines the wire winding and tin dipping processes of the stator. During this processing, no manual operation is required, and it is automatically carried out by the device, with higher efficiency and lower labor cost.

[0005] Another object of the present invention is to provide a fully automatic wire winding and tin dipping device, which does not require the stator to be flipped by means of a manipulator or other structures between the stator wire winding process and the tin dipping process, further improving the stator processing efficiency.

[0006] In order to achieve the above objects, the technical solution of the present invention.

[0007] A fully automatic wire winding and tin dipping device, characterized in that the device includes a feeding mechanism capable of feeding the stator with its pins facing downwards, a wire winding device for winding the stator with its pins facing downwards, a tin dipping device for dipping the pins of the stator, and a conveying mechanism for conveying the stator; the feeding mechanism, the wire winding device, and the tin dipping device are all corresponding in position to the conveying mechanism, so that the conveying mechanism sequentially conveys the stator with its pins facing downwards to the wire winding process and the tin dipping process. In the present invention, the feeding mechanism feeds the stator with its pins facing downwards, and then, under the conveyance of the conveying mechanism, conveys the stator fed by the feeding mechanism to the wire winding device, and the wire winding device winds the stator; when the stator winding is completed, the conveying mechanism conveys the stator to the tin dipping device to dip the pins of the stator after winding; during this processing process, only manual operations are required when the machine is started and when the stator is placed into the feeding mechanism, and no manual operations are required at other times, greatly reducing the labor cost and increasing the processing efficiency; and because the stator is fed with its pins facing downwards by the feeding mechanism from the beginning, there is no need to flip the stator through structures such as a manipulator between the wire winding process and the tin dipping process of the stator, further improving the processing efficiency of the stator. Among them, the wire winding device is a prior art; the implementation principle of the wire winding device for winding the stator with its pins facing downwards is a prior art, such as flipping the wire winding structure of the existing wire winding device for winding the stator with its pins facing upwards (the wire winding structure is below and the structure for fixing the stator is above).

[0008] Further, the wire winding device, the feeding mechanism, and the tin dipping device are arranged in sequence, the conveying mechanism is located on one side of the wire winding device and the feeding mechanism, and the conveying mechanism is connected to the tin dipping device. The setting of the positions among the above-mentioned wire winding device, feeding mechanism, and tin dipping device can make the device more efficient during the wire winding and tin dipping process; the feeding mechanism can transport the stator from feeding to wire winding and then to tin dipping by shuttling between the wire winding device and the tin dipping device, which is more time-saving and efficient compared to the design where the feeding mechanism, wire winding device, and tin dipping device are arranged in sequence.

[0009] Further, the feeding mechanism includes a vibrating bowl, a feeding grasping mechanism, and more than one placing member for placing the stator, the vibrating bowl and the placing member are both corresponding to the feeding grasping mechanism, so that the feeding grasping mechanism grasps and places the stator conveyed out by the vibrating bowl on the placing member; the placing member is corresponding in position to the conveying mechanism, so that the conveying mechanism grasps the stator on the placing member and conveys it. The number of placing members for placing the stator can be two, three, or more than four, which can respectively realize placing different numbers of stators. The implementation of the feeding grasping mechanism is a prior art, such as a clamping cylinder and a two-axis motion component using a motor and / or a cylinder, or a manipulator.

[0010] Further, the conveying mechanism includes a conveying slide rail, a conveying clamping assembly, and a conveying motion assembly. The conveying clamping assembly is movably arranged on the conveying slide rail, and the conveying clamping assembly is connected to the conveying motion assembly so that the conveying motion assembly drives the conveying clamping assembly to move on the conveying slide rail. The winding device, the placing member, and the soldering dipping device all correspond to the conveying clamping assembly.

[0011] Further, the conveying clamping assembly includes a forward pushing assembly and more than one clamping cylinder. The clamping cylinder is fixedly arranged on the forward pushing assembly to move forward or backward under the push of the forward pushing assembly.

[0012] Further, the conveying clamping assembly further includes an upward pushing assembly. The forward pushing assembly is fixedly arranged on the upward pushing assembly to rise or fall under the push of the upward pushing assembly. The upward pushing assembly and the forward pushing assembly are both prior arts, such as realized by using a motor and a lead screw; this setting makes it more convenient for the conveying clamping assembly to clamp stators of different heights.

[0013] Further, a receiving groove and a conveying path are arranged in the vibrating bowl to feed the stators in the receiving groove through the conveying of the conveying path. It is characterized in that the conveying path includes a screening path for screening out stators with qualified pin lengths. A screening part for screening stators is arranged in the screening path. A pin channel for allowing one pin of the stator to pass through is formed between the screening part and one side of the screening path. A screening opening is arranged on the other side of the screening path corresponding to the pin channel. The screening path is inclined in the section of the pin channel and the screening opening, and the screening opening is located below and the pin channel is located above.

[0014] Further, the conveying path further includes a positioning path. A positioning block for abutting against two opposite pins of the stator is arranged at the positioning path so that when the stator is transported on the positioning path, the two opposite pins abut against the positioning block. The positioning path is connected to the screening path.

[0015] Further, the conveying path further includes a flipping path. The flipping path is connected to the screening path. The stator with pins facing upward enters from the screening path, and after passing through the flipping path, the stator is flipped so that the pins of the stator face downward for conveying.

[0016] Further, a sensor for sensing the stator is arranged at the outlet of the flipping path.

[0017] The beneficial effects of the present invention are as follows: Compared with the prior art, in the present invention, the feeding mechanism feeds the stator with its pins facing downwards. Then, under the conveyance of the conveying mechanism, the stator fed by the feeding mechanism is conveyed to the winding device, and the stator is wound by the winding device; after the stator winding is completed, the conveying mechanism conveys the stator to the tin dipping device to dip the pins of the stator after winding; during this processing process, manual operation is only required when the machine is started and the stator is placed into the feeding mechanism, and no manual operation is required at other times, greatly reducing the labor cost and increasing the processing efficiency; and because the stator is fed with its pins facing downwards by the feeding mechanism from the beginning, there is no need to flip the stator through structures such as a manipulator between the stator winding process and the tin dipping process, further improving the stator processing efficiency.

[0030] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] See Figures 1-12 , a fully automatic wire winding and tin dipping device, characterized in that the device includes a feeding mechanism capable of feeding the stator with its pins facing downwards, a wire winding device 2 for winding the stator with its pins facing downwards, a tin dipping device 3 for dipping the pins of the stator, and a conveying mechanism 4 for conveying the stator; the feeding mechanism, the wire winding device 2 and the tin dipping device 3 are all connected to the conveying mechanism 4, so that the conveying mechanism sequentially conveys the stator with its pins facing downwards to the wire winding process and the tin dipping process.

[0032] In this embodiment, the wire winding device 2, the feeding mechanism and the tin dipping device 3 are arranged in sequence, the conveying mechanism 4 is located on one side of the wire winding device 2 and the feeding mechanism, and the conveying mechanism 4 is connected to the tin dipping device 3.

[0033] In this embodiment, the feeding mechanism includes a vibrating disk 1, a feeding grasping mechanism 5 and one or more placing members 51 for placing the stator. The vibrating disk 1 and the placing member 51 correspond to the feeding grasping mechanism 5 respectively, so that the feeding grasping mechanism 5 grasps the stator conveyed out by the vibrating disk 1 and places it on the placing member 51; the placing member 51 corresponds to the position of the conveying mechanism 4, so that the conveying mechanism 4 grasps the stator on the placing member 51 and transports it.

[0034] In this embodiment, the conveying mechanism 4 includes a conveying slide rail 41, a conveying clamping assembly 42 and a conveying movement assembly 43. The conveying clamping assembly 42 is movably arranged on the conveying slide rail 41, and the conveying clamping assembly 42 is connected to the conveying movement assembly 43, so that the conveying movement assembly 43 drives the conveying clamping assembly 42 to move on the conveying slide rail 41. The wire winding device 2, the placing member 51 and the tin dipping device 3 all correspond to the conveying clamping assembly 42.

[0035] In this embodiment, the conveying clamping assembly 42 includes a front pushing assembly 421 and one or more clamping cylinders 422. The clamping cylinders 422 are fixedly arranged on the front pushing assembly 421 to move forward or backward under the push of the front pushing assembly 421.

[0036] In this embodiment, the conveying clamping assembly 42 further includes an upward pushing assembly 423. The front pushing assembly 421 is fixedly arranged on the upward pushing assembly 423 to rise or fall under the push of the upward pushing assembly 423.

[0037] See Figures 4-6, in this embodiment, a receiving groove 11 and a conveying path 12 are provided in the vibrating disk 1 to feed the stator in the receiving groove 11 through the conveying of the conveying path 12. The conveying path 12 includes a screening path 121 for screening out stators with qualified pin lengths. A screening part for screening the stator is provided in the screening path 121. A pin channel 1212 for allowing one pin of the stator to pass through is formed between the screening part and one side of the screening path 121. A screening opening 1213 is provided on the other side of the screening path 121 corresponding to the pin channel 1212. The screening path 121 is inclined in the section between the pin channel 1212 and the screening opening 1213, and the screening opening 1213 is located below while the pin channel 1212 is located above. Through the vibration of the vibrating disk, the stator in the receiving groove is conveyed and fed through the conveying path. Among them, when the stator passes through the screening path, only the stator with a pin length meeting the requirements can pass through. When the pin enters the pin channel, it abuts against the screening part. When the pin cannot abut against the screening part, it will fall out from the screening opening due to the inclined setting of the screening path, so that the stator with insufficient pin length or missing pins can be screened out. There is no need for manual feeding, and continuous feeding is carried out in the form of a vibrating disk, with higher efficiency.

[0038] In this embodiment, the screening part includes a screening fixing part 1214 and a screening movable part 1215. The screening fixing part 1214 is fixedly arranged on the screening path 121, and the screening movable part 1215 is movably arranged on the screening fixing part 1214. The pin channel 1212 is formed by the screening movable part 1215 and one side of the screening path 121. The position of the screening movable part on the screening fixing part can be adjusted according to the required pin length of the stator to be screened. The screening part may further include a screening locking part (not shown in the figure) that is detachably connected to both the screening fixing part and the screening movable part for locking the screening movable part after movement on the screening fixing part.

[0039] In this embodiment, the conveying path 12 also includes a positioning path 122, and a positioning block 1221 is provided on the positioning path 122 for abutting against two opposite pins of the stator, so that the two opposite pins of the stator are abutted against the positioning block 1221 when the stator is transported on the positioning path 122, and the positioning path 122 is connected with the screening path 121. The stator loaded by the vibration plate has three pins in total (the first pin A, the second pin B and the third pin C), among which the first pin and the second pin are relatively and symmetrically arranged, and the third pin is located on the symmetry axis of the first pin and the second pin; before the stator enters the screening path, it needs to pass through the positioning path; if the lengths of the first pin and the second pin meet the requirements, only when the first pin and the second pin abut against the positioning block, the stator can move from the positioning path to the screening path, and at this time the third pin smoothly enters the pin channel. If the third pin is not long enough to abut on the screening part, the stator will fall from the screening port; if the lengths of the first pin and the second pin meet the requirements, but the first pin and the second pin do not abut on the positioning block, the stator will vibrate back into the receiving slot before entering the screening path; if the lengths of the first pin and the second pin do not meet the requirements, the position of the third pin cannot be adjusted, so that it cannot smoothly enter the pin channel and cannot abut on the screening part, which will cause the stator to fall from the screening port. Through the combination of the positioning path and the screening path, any one of the three stator pins that is not long enough will not be transported by the vibration plate.

[0040] In this embodiment, the positioning block 1221 is movably arranged on the positioning path 122, and the height of the positioning block 1221 in the positioning path 122 is adjusted so that the positioning block 1221 can abut against stator pins of different heights. The height of the positioning block in the positioning path can be adjusted according to the length of the stator pins to be screened, and the positioning block can also be provided with a positioning locking member (not shown) detachably connected to the positioning block, which is used to lock the positioning block on the positioning path after the movement.

[0041] In this embodiment, the conveying path 12 further includes a flipping path 123 , which is connected to the screening path 121 . The stator with pins facing upward enters from the screening path 121 , and after passing through the flipping path 123 , the stator is flipped so that the stator pins are conveyed downward.

[0042] In this embodiment, the inlet of the screening path 121 is horizontally arranged, and the outlet of the screening path 121 is horizontally arranged, so that the stator passing through the screening path 121 is flipped by ninety degrees; the inlet of the flipping path 123 is horizontally arranged, and its outlet is horizontally arranged, so that the stator passing through the screening path 121 and the flipping path 123 in sequence is flipped by one hundred and eighty degrees. The cooperation of the flipping path and the screening path can enable the stator to be fed with its pins facing downwards, so that after the subsequent stator winding, it can directly enter the tin dipping process without the need to flip the stator in the middle.

[0043] In this embodiment, the flipping path 123 includes a connecting channel 1231 and a flipping channel 1232. The two ends of the connecting channel 1231 are respectively connected to the screening path 132 and the flipping channel 1232. An anti-detachment portion 1233 for preventing the stator from detaching is provided on the flipping channel 1232. The flipping channel 1232 includes flipping channel side walls 1234 on both sides for abutting against the stator pins. When the stator enters the flipping channel 1232, the two opposite pins of the stator respectively abut against the outer sides of the flipping channel side walls 1234 on both sides of the flipping channel 1232. After the stator enters the connecting channel, its posture can be adjusted by vibration in the connecting channel, and it is fed in a posture where the two opposite pins (the first pin and the second pin) respectively abut against the outer sides of the flipping channel side walls on both sides of the flipping channel, which is more conducive to the feeding and grasping mechanism to grasp and place it on the placing part in the correct posture.

[0044] In this embodiment, a sensor for sensing the stator is provided at the outlet of the flipping channel 123. The sensor can sense the stator passing through the outlet of the flipping channel, which is convenient for the feeding and grasping mechanism to grasp.

[0045] In this embodiment, a protective layer for protecting the stator pins is provided in the vibrating bowl 1. The protective layer is made of a soft material, which can prevent the stator pins from being damaged during the vibrating transportation of the stator. For example, the protective layer can be made of polyurethane glue.

[0046] See Figures 7-12, in this embodiment, the soldering dipping device 3 includes a machine frame 31, a soldering dipping motion mechanism 32, a soldering dipping grasping mechanism 33, and a soldering furnace 34. The soldering furnace 34 and the soldering dipping motion mechanism 32 are both fixedly arranged on the machine frame 31. The soldering dipping grasping mechanism 33 is fixedly arranged on the soldering dipping motion mechanism 32 so that the soldering dipping grasping mechanism 33 can move forward and backward and up and down under the drive of the soldering dipping motion mechanism 32. This soldering dipping device further includes a terminal detection mechanism 35 for detecting whether the stator soldering dipping is qualified, and a defective product collection mechanism 36 for collecting unqualified stators. The terminal detection mechanism 35 and the defective product collection mechanism 36 are both fixedly arranged on the machine frame 31, and the soldering dipping grasping mechanism 33 moves on the soldering furnace 34, the terminal detection mechanism 35, and the defective product collection mechanism 36 under the drive of the soldering dipping motion mechanism 32. Among them, the implementation principle of the terminal detection mechanism is prior art. For example, the terminal detection mechanism includes detection guide pins. The motion mechanism drives the grasping mechanism to move onto the detection guide pins so that the stator terminals are in contact with the detection guide pins to measure the resistance, and whether the soldering dipping effect of the stator terminals is qualified is identified according to the measured resistance value. The soldering furnace 34 can be heated in real time so that the molten tin in the soldering furnace 34 remains in a molten state. In this soldering dipping device 3, the motion mechanism drives the grasping mechanism to move on the soldering furnace, the terminal detection mechanism, and the defective product collection mechanism, so that after the grasping mechanism grasps the stator, it can move down to the soldering furnace for soldering dipping, rise after the soldering dipping is completed and move to the terminal detection mechanism, and descend at the terminal detection mechanism to detect the soldering dipping condition of the stator pins, and judge whether the stator soldering dipping is qualified, so as to screen out non-conforming stators and avoid defective products during the soldering dipping process of the stators. At the same time, the screened defective products do not need to be manually removed. Based on the design of the defective product collection mechanism, after the defective products are judged, the motion mechanism drives the grasping mechanism to move to the defective product collection mechanism and put the defective products into the defective product collection mechanism. The above structural arrangement can not only ensure the qualification rate of stator soldering dipping, but also improve the processing efficiency and reduce the labor cost. The motion mechanism can adopt a two-axis motion mechanism or a manipulator.

[0047] In this embodiment, the soldering dipping grasping mechanism 33 includes more than one clamping cylinder 331. More than one clamping cylinder 331 are all fixedly arranged on the soldering dipping motion mechanism 32, and a clamping fixture 332 for clamping the stator is fixedly arranged on the output shaft of the clamping cylinder 331. The arrangement of the clamping cylinder and the clamping fixture makes the grasping mechanism more stable when grasping the stator; and when there are multiple clamping cylinders, the multiple clamping cylinders can execute different instructions as needed.

[0048] In this embodiment, the tin dipping device further includes a tin level detecting assembly for detecting the height of the tin liquid in the tin furnace 34, and the tin level detecting assembly 37 is fixedly arranged on the dipping movement mechanism 32. The arrangement of the tin level detecting assembly can measure the height of the tin liquid in the tin furnace, so that when the grasping mechanism grabs the stator and descends, it can descend to an appropriate height, neither too low nor too high.

[0049] In this embodiment, the movement mechanism 32 includes a movement support 321, a displacement assembly 322 and a lifting assembly 323. The movement support 321 is fixedly arranged on the machine frame 31. The lifting assembly 323 is movably arranged on the movement support 321 through a slide rail and slider structure. The displacement assembly 322 is fixedly arranged on the movement support 321, and the lifting assembly 323 is connected to the displacement assembly 322 so that the lifting assembly 323 moves on the movement support 321 under the drive of the displacement assembly 322. The dipping grasping mechanism 33 and the tin level detecting assembly 37 are both fixedly arranged on the lifting assembly 323 to move up and down under the drive of the lifting assembly 323. The implementation principle of the displacement assembly is prior art, such as realized by using a motor and a lead screw.

[0050] In this embodiment, the lifting assembly 323 includes a lifting fixing member 3231, a tin level detecting lifting assembly 3232 and a grasping lifting assembly 3233. The lifting fixing member 3231 is movably arranged on the movement support 321 through a slide rail and slider structure. The grasping lifting assembly 3233 is movably arranged on the lifting fixing member 3231 through a slide rail and slider structure. The tin level detecting lifting assembly 3232 is fixedly arranged on the grasping lifting assembly 3233. The tin level detecting assembly 37 is fixedly arranged on the tin level detecting lifting assembly 3232 to move up and down under the drive of the tin level detecting lifting assembly 3232. The dipping grasping mechanism 33 is fixedly arranged on the grasping lifting assembly 3233 to move up and down under the drive of the grasping lifting assembly 3233. The drive of the grasping lifting assembly is prior art, such as realized by using a motor and a lead screw to drive the grasping lifting assembly to move up and down at the lifting fixing member 3231, thereby driving the dipping grasping mechanism 33 to descend or ascend. The implementation of the tin level detecting lifting assembly is prior art, such as realized by using a cylinder to drive the tin level detecting assembly to descend or ascend. The tin level detecting assembly 37 is two or more tin level detecting needles. The principle of the tin level detecting needle for testing the height position of the tin liquid is prior art. The tin level detecting needle is arranged at the interval of two or more clamping cylinders. The arrangements of the tin level detecting lifting assembly and the grasping lifting assembly enable the grasping mechanism and the tin level detecting assembly to rise or descend asynchronously, so that when the device dips the stator, it can control the grasping mechanism or the tin level detecting assembly to rise or descend as needed, making the dipping process more efficient and rapid.

[0051] In this embodiment, the tin dipping device further includes a flux mechanism 38 for placing flux. The flux mechanism 38 is arranged on the frame 31, and the tin dipping and grasping mechanism 33 moves on the flux mechanism 38, the tin furnace 34, the terminal detection mechanism 35 and the defective product collection mechanism 36 under the drive of the tin dipping movement mechanism 32. The setting of the flux mechanism can dip the flux before the stator is dipped in tin, improving the subsequent tin dipping effect.

[0052] In this embodiment, the flux mechanism 38 includes a flux containing groove 381 for containing flux. A flux support plate 382 is arranged in the flux containing groove 381. Flux guide posts 383 corresponding to the stator terminals are arranged on the flux support plate 382. Through holes 3831 penetrating the flux guide posts and the flux support plate are arranged on the flux guide posts 383. A cover plate 3811 can also be arranged on the flux containing groove 381. Through holes for adapting to the stator are arranged at the positions of the cover plate 3811 corresponding to the flux guide posts 383, which can prevent a large amount of external dust from mixing into the flux while covering the flux containing groove 381 and does not affect the process of the stator dipping into the flux. The flux containing groove is filled with flux. When the stator dips in the flux, the stator pins are aligned with the through holes on the flux guide posts. After the stator descends, the pins extend into the through holes on the flux guide posts. Since this through hole penetrates to the flux support plate, the pins can dip the flux through the through holes on the flux guide posts. The setting of the flux guide posts and their through holes can prevent the stator from dipping too deep into the flux when the pins dip in the flux.

[0053] In this embodiment, the soldering flux mechanism 38 further includes a soldering flux support 384 and a soldering flux lifting assembly 385. The soldering flux support 384 is fixedly arranged on the frame 31. Both the soldering flux lifting assembly 385 and the soldering flux receiving groove 381 are fixedly arranged on the soldering flux support 384. The soldering flux lifting assembly 385 is connected to the soldering flux tray 382 to control the lifting movement of the soldering flux tray 382 in the soldering flux receiving groove 381. The soldering flux lifting assembly 385 can be implemented by using a soldering flux lifting cylinder 3851, a soldering flux lifting plate 3852, and a soldering flux lifting shaft 3853. Specifically, the tail of the soldering flux lifting cylinder 3851 is fixedly arranged below the soldering flux support 384. The soldering flux lifting plate 3852 is located below the soldering flux support 384 and is fixed on the output shaft of the soldering flux lifting cylinder 3851. One end of the soldering flux lifting shaft 3853 is fixedly arranged at both ends of the soldering flux lifting plate 3852. The other ends of the two soldering flux lifting shafts 3853 pass through the soldering flux support 384 and are respectively fixed to both ends of the soldering flux tray 382. The setting that the soldering flux lifting assembly can drive the soldering flux tray to perform lifting movement in the soldering flux receiving groove. When the height of the soldering flux in the soldering flux receiving groove decreases, the soldering flux tray is controlled to descend in the soldering flux receiving groove, so that when the pins of the stator extend into the through holes of the soldering flux guide posts, they can be immersed in enough soldering flux.

[0054] In this embodiment, a finished product placement area 311 for placing the finished products after the stator is dip-tinned is further arranged on the frame 31. The finished product placement area 311, the soldering flux mechanism 38, the defective product collection mechanism 36, the terminal detection mechanism 35, and the soldering furnace 34 are arranged in sequence on the frame 31. The finished product placement area can be a storage groove. The setting of this finished product placement area enables the stator, after the dip-tin detection is completed, to be automatically moved to the finished product placement area and placed down by the grasping mechanism driven by the motion mechanism without manual removal and placement. The arrangement of the finished product placement area, the soldering flux mechanism, the defective product collection mechanism, the terminal detection mechanism, and the soldering furnace in sequence on the frame makes the processing efficiency of this device higher during processing.

[0055] In this embodiment, the defective product collection 36 mechanism is a storage groove.

[0056] In this embodiment, a tin scraping mechanism 39 for scraping the oxide layer on the surface of the molten tin in the soldering furnace 34 is fixedly arranged on the frame 31. The tin scraping mechanism 39 corresponds to the position of the soldering furnace 34.

[0057] In this embodiment, the tin scraping mechanism 39 includes a tin scraping support 391, a tin scraping lifting assembly 392, a tin scraping front-back assembly 393, and a tin scraping plate 394. The tin scraping support 391 is fixedly arranged on the frame 31, and the tin scraping lifting assembly 392 is fixedly arranged on the tin scraping support 391; the tin scraping front-back assembly 393 is fixedly arranged on the tin scraping lifting assembly 392 to move up and down driven by the tin scraping lifting assembly 392; the tin scraping plate 394 is fixedly arranged on the tin scraping front-back assembly 393 to move back and forth driven by the tin scraping front-back assembly 393, and the tin scraping plate 394 corresponds to the position of the tin furnace 34. The implementation principles of the tin scraping lifting assembly 392 and the tin scraping front-back assembly 393 are both prior arts, such as being implemented by using air cylinders. The cooperation of the tin scraping lifting assembly and the tin scraping front-back assembly enables the tin scraping plate to cope with the tin liquid at different heights in the tin furnace.

[0058] In this embodiment, the tin dipping device further includes a feeding mechanism for conveying the stator. The feeding mechanism is fixedly arranged on the frame 31 and corresponds to the position of the tin dipping grasping mechanism 33; the feeding mechanism includes a tin dipping feeding guide rail 312, a feeding driving assembly, and a stator placing member 313 for placing the stator; the stator placing member 313 is movably arranged on the tin dipping feeding guide rail 312, the feeding driving assembly is fixedly arranged on the frame 31, and the feeding driving assembly is connected to the stator placing member 313 to drive the stator placing member 313 to move on the tin dipping feeding guide rail 312. The feeding driving assembly is implemented by using structures such as a motor and a lead screw. The conveying and clamping assembly corresponds to the position of the stator placing member. After the conveying and clamping assembly places the stator on the stator placing member, the stator is conveyed by the movement of the stator placing member on the feeding track, eliminating the need for manual placement and improving the efficiency.

[0059] Working process:

[0060] Wire winding: The vibrating bowl feeds the stator with the pins facing downwards. When the inductor senses that there is a stator at the outlet of the vibrating bowl (i.e., the outlet of the flipping path), the feeding and grasping mechanism grabs and places the stator on the placing member; the conveying and clamping assembly clamps the stator on the placing member and moves on the conveying track through the conveying movement assembly, moving to the wire winding device. The conveying and clamping assembly places the stator on the processing position of the wire winding device, and the wire winding mechanism winds the stator; after the wire winding is completed, the conveying and clamping assembly clamps the stator again and moves on the conveying track through the conveying movement assembly to the stator placing member, and places the stator on the stator placing member. At this time, the stator placing member is located beside the placing member.

[0061] Tin dipping: The stator placement part of the loading mechanism moves on the tin dipping feeding guide rail driven by the feeding drive assembly to the position below the grasping mechanism; the motion mechanism drives the grasping mechanism to descend to grasp the stator on the stator placement part and then ascend, and drives the stator to move to the fluxing agent mechanism for flux dipping; then the motion mechanism drives the stator grasped by the grasping mechanism to move to the tin furnace; the tin level measuring lifting assembly of the motion mechanism drives the tin level measuring needle to descend into the tin furnace to measure the height of the tin liquid, and after the measurement, the tin level measuring lifting assembly drives the tin level measuring needle to ascend, and the tin scraping mechanism scrapes the oxide layer on the surface of the tin liquid in the tin furnace, and then the grasping lifting assembly of the motion mechanism drives the grasping mechanism to descend, so that the pins of the stator grasped by the grasping mechanism descend to an appropriate height for tin dipping of the stator pins; after the tin dipping is completed, the grasping lifting assembly of the motion mechanism drives the grasping mechanism to ascend, and then the motion mechanism drives the grasping mechanism to move to the terminal detection mechanism to detect the tin dipping condition of the stator pins. When there are unqualified stators, the motion mechanism drives the grasping mechanism to move to the defective product collection mechanism, and by controlling the release of the clamping cylinder corresponding to the unqualified stator, the unqualified stator falls into the defective product collection mechanism; when there are no unqualified stators or the unqualified stators have been placed in the defective product collection mechanism, the motion mechanism drives the grasping mechanism to move to the finished product placement area and places all the stators there.

[0062] The beneficial effects of the present invention are as follows: Compared with the prior art, in the present invention, the stator is loaded with its pins facing down by the loading mechanism, and then under the conveyance of the conveying mechanism, the stator loaded by the loading mechanism is conveyed to the winding device, and the stator is wound by the winding device; when the stator winding is completed, the conveying mechanism conveys the stator to the tin dipping device to dip the pins of the stator after winding; in this processing process, only manual operations are required when the machine is started and the stator is placed into the loading mechanism, and no manual operations are required at other times, greatly reducing the labor cost and increasing the processing efficiency; and because the stator is loaded with its pins facing down by the loading mechanism from the beginning, there is no need to flip the stator through structures such as a manipulator between the stator winding process and the tin dipping process, further improving the stator processing efficiency.

[0063] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
