Technical Field

[0001] The invention relates to the technical field of motor coil assembly, and in particular to an assembly device for assembling a PCB and a stator group. Background Art

[0002] The stator winding refers to the winding installed on the stator. The winding is assembled into a whole by multiple stator cores. At the same time, the stator core has multiple pins, and a ring-shaped circuit board needs to be set on the pins. For example, the patent number CN201822005333.X discloses a stator core with a circuit board connected to a coil. The technical solution includes a core body provided with a winding, a conductor for electrically connecting to a single winding, and a circuit board electrically connected to the conductor. The circuit board cover is connected to the core body and electrically connected to the winding through the conductor.

[0003] For the assembly of the circuit board and the stator core, since the pins on the stator core are skewed, it is difficult to directly connect the circuit board cover to the stator core. Therefore, in the prior art, it is generally manually aligned, and then the circuit board is placed on the stator core and the pins are inserted into the circuit board. This results in a very slow assembly speed and cannot achieve automated production. Summary of the invention

The assembly device for assembling a PCB and a stator group comprises a machine platform, a first shaping mechanism arranged on the machine platform, and an assembly mechanism arranged on the machine platform. The first shaping mechanism comprises a bracket arranged on the machine platform, a slide rail and slider assembly arranged on the bracket, a shaping mold slidably arranged on the slide rail and slider assembly, and a second driving cylinder driving the shaping mold to slide. The sliding direction of the shaping mold is parallel to the direction of gravity, and the shaping mold is provided with a plurality of shaping holes through it. The plurality of shaping holes are arranged in a circumference, and the central axis of the shaping hole is parallel to the central axis of the shaping mold and the diameter of the shaping hole is greater than the diameter of the pin. The assembly mechanism comprises a moving component arranged on the machine platform, a second shaping component slidably arranged on the moving component, and a suction component slidably arranged on the moving component. The structure of the second shaping component is the same as that of the first shaping mechanism and also has shaping holes. The diameter of the shaping hole of the second shaping component is smaller than that of the shaping hole of the first shaping mechanism, and the pin is shaped by first using the shaping hole with a large diameter and then using the shaping hole with a small diameter. The suction component is used to suck the PCB and put the PCB on the pin.

[0006] Furthermore, the assembly device for assembling the PCB and the stator assembly further includes a conveying mechanism disposed on the machine platform, and a material dividing mechanism disposed on the machine platform.

[0007] Furthermore, the conveying mechanism also includes a conveying track arranged on the machine platform, two loading and unloading tracks arranged on the machine platform, at least one carrier plate slidably arranged on the conveying track, a plurality of position sensors arranged at intervals on the conveying track, and two locking assemblies arranged on both sides of the conveying track. The two loading and unloading tracks are respectively located at both ends of the conveying track and can be spliced ​​and connected with the conveying track.

[0008] Furthermore, the locking assembly includes a mounting plate arranged on the conveying track, a slider slidably arranged on the mounting plate, and a first driving cylinder driving the slider to move, and a locking finger is provided on the facing sides of the two sliders of the two locking assemblies.

[0009] Furthermore, the material dividing mechanism includes a base arranged on the machine platform, four limit columns vertically arranged on the base and distributed in a circle, a lifting cylinder arranged on the base, and two height sensors located on both sides of the base.

[0012] Furthermore, the shell is a cylindrical structure with a hollow interior, and includes a hollow cylinder, a top plate arranged at one end of the hollow cylinder, and a bottom plate arranged at the other end of the hollow cylinder. One end of the connecting shaft is connected to the top plate, and the other end is connected to the buffer plate, and the suction nozzle passes through the buffer plate and the bottom plate.

[0013] Compared with the prior art, the structure of the second shaping component of the assembly device for assembling PCB and stator group provided by the present invention is the same as that of the first shaping mechanism, and also has a shaping hole. The crooked pin will be squeezed by the inner wall of the shaping hole and straightened. The diameter of the shaping hole of the second shaping component is smaller than the diameter of the shaping hole of the first shaping mechanism. The pin is shaped twice, first using a large diameter shaping hole and then a small diameter shaping hole. This can better shape some severely crooked pins, avoid directly using a small shaping hole, which causes the severely crooked pins to be unable to be inserted into the shaping hole, and ensure the shaping effect and efficiency. The suction component can absorb the PCB board, and then the moving component drives the suction component to move above the stator, and the vertical moving component drives the suction component to descend, so that the PCB board is sleeved on the pins of the stator, realizing the automated assembly of the entire process.

[0023] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0024] like Figures 1 to 9 As shown, it is a schematic diagram of the structure of the assembly device for assembling a PCB and a stator group provided by the present invention. The assembly device for assembling a PCB and a stator group includes a machine 10, a conveying mechanism 20 arranged on the machine 10, a first shaping mechanism 30 arranged on the machine 10, a material dividing mechanism 40 arranged on the machine 10, and an assembly mechanism 50 arranged on the machine 10. It can be imagined that the assembly device for assembling a PCB and a stator group also includes some other functional modules, such as electrical components, sensors, and drive components, etc., which are well known to those skilled in the art and will not be repeated here.

[0025] First of all, it should be explained that the assembly device for assembling a PCB and a stator assembly is used to assemble a PCB and a stator assembly, and the stator assembly includes an iron core body and a plurality of pins arranged on the iron core body and distributed in a circumference. The stator assembly and the PCB should be prior art and will not be described in detail here.

[0026] The machine 10 is used to carry the above-mentioned functional modules, so the machine 10 is provided with a variety of functional structures, such as screws, avoidance holes, clamps, etc. to complete the installation and assembly of the above-mentioned functional modules. It can be set according to actual needs and will not be described in detail one by one here.

[0027] The conveying mechanism 20 includes a conveying track 21 arranged on the machine platform 10, two loading and unloading tracks 22 arranged on the machine platform 10, at least one carrier plate 23 slidably arranged on the conveying track 21, a plurality of position sensors 24 arranged at intervals on the conveying track 21, and two locking components 25 arranged on both sides of the conveying track 21.

[0028] The conveying track 21 is used to drive the carrier plate 23 to move, so the conveying track 21 should also be provided with a driving device for driving the carrier plate 23 to slide on the conveying track 21, such as a rotating motor, belts and other parts, the carrier plate 23 is connected to the belt, and the belt is driven to rotate by the rotating motor. It should be the existing technology and will not be repeated here.

[0029] The two loading and unloading tracks 22 are respectively located at the two ends of the conveying track 21 and can be spliced ​​and connected with the conveying track 21. The two loading and unloading tracks 22 are used for loading and unloading, respectively. The loading and unloading tracks 22 are slidably arranged on the machine table 10 through guide rails. When loading, the carrier plate 23 equipped with the stator is placed into the loading and unloading tracks 22 manually or by means of mechanical claws, and then the loading and unloading tracks 22 slide to the port at one end of the conveying track 21 and are spliced ​​and connected. When unloading, the carrier plate 23 carrying the assembled stator slides into another loading and unloading track 22, and then the loading and unloading track 22 slides away and moves to the next process. It can be imagined that the loading and unloading tracks 22 should also have a driving device to drive the carrier plate 23 to slide, so that the carrier plate 23 slides into the conveying track 21.

[0030] The arrangement direction of the plurality of position sensors 24 is parallel to the sliding direction of the carrier plate 23. In the present embodiment, the position sensor 24 is a photoelectric sensor and a diffuse reflection type photoelectric switch. When the carrier plate 23 carrying the stator passes through the position sensor 24, the light emitted by the position sensor 24 is blocked and part of the light is reflected back. The position sensor 24 receives the light signal, thereby knowing the position of the carrier plate 23.

[0031] The locking assembly 25 includes a mounting plate 251 disposed on the conveying track 21, a slider 252 slidably disposed on the mounting plate 251, and a first driving cylinder 253 driving the slider 252 to move. A locking finger 254 is provided on the opposite sides of the two sliders 252 of the two locking assemblies 25. When the driving cylinder 253 drives the slider 252 to move toward the stator, the locking finger 254 will be inserted into the stator, thereby fixing the stator to prevent the stator from moving and rotating during assembly. At the same time, the locking assembly 25 should also be provided with a position sensor to determine whether the carrier plate 23 moves between the two locking assemblies 25.

[0032] The first shaping mechanism 30 includes a bracket 31 arranged on the machine platform 10, a slide block assembly 32 arranged on the bracket 31, a shaping mold 33 slidably arranged on the slide block assembly 32, and a second driving cylinder 34 that drives the shaping mold 33 to slide.

[0033] The first shaping mechanism 30 is located on one side of the position sensor 24. The slide rail and slider assembly 32 is composed of a slide rail, a slider, and a slide plate, and is used to support the sliding of the shaping mold 33, which should be the prior art. The sliding direction of the shaping mold 33 is parallel to the direction of gravity, thereby driving the shaping mold 33 to move vertically. The shaping mold 33 is an annular structure, and the central axis of the shaping mold 33 is parallel to the central axis of the stator. The shaping mold 33 is provided with a plurality of shaping holes 331, and the plurality of shaping holes 331 are arranged in a circular shape. The central axis of the shaping hole 331 is parallel to the central axis of the shaping mold 33, and the diameter of the shaping hole 331 is larger than the diameter of the pin, so that the shaping hole 331 can be sleeved on the pin of the stator. When the carrier plate 23 moves to just below the shaping mold 33, the second driving cylinder 34 drives the shaping mold 33 to descend, so that the pins on the stator are inserted into the shaping holes 331. The crooked pins will be squeezed by the inner wall of the shaping hole 331 and straightened, thereby shaping the pins to facilitate the installation of the PCB.

[0034] The material dividing mechanism 40 includes a base 41 disposed on the machine platform 10 , four limit columns 42 vertically disposed on the base 41 and distributed in a circle, a lifting cylinder 43 disposed on the base 41 , and two height sensors 44 located on both sides of the base 41 .

[0035] A plurality of the limiting posts 42 are arranged on the base 41, and the other end is freely arranged. A limiting portion 421 is provided inside the plurality of limiting posts 42 in the same extension direction as the limiting posts 42, so that the cross section of the limiting posts 42 is convex. The limiting portion 421 fits with the notch of the PCB board, so that the PCB board is fixed between the plurality of limiting posts 42 and can only move vertically. The lifting cylinder 43 is located between the plurality of limiting posts 42, and the output end of the lifting cylinder 43 supports a stack of PCB boards and can drive the PCB boards to move vertically. The height sensor 44 is arranged at the same height as the freely arranged end of the limiting post 42 through a bracket, and is used to detect the position of the PCB board. When the assembly mechanism 50 takes away a PCB board, the signal of the height sensor 44 is no longer blocked, and the lifting cylinder 43 drives a stack of PCB boards to move up one position and blocks the height sensor 44 again.

[0036] The assembling mechanism 50 includes a moving component 51 disposed on the machine platform 10 , a second shaping component 52 slidably disposed on the moving component 51 , and a material suction component 53 slidably disposed on the moving component 51 .

[0037] The moving assembly 51 is composed of components such as a slide rail, a motor, and a belt, and is used to drive the second shaping assembly 52 and the suction assembly 53 to move. The moving assembly 51 should be a prior art and will not be described in detail here.

[0038] The structure of the second shaping component 52 is the same as that of the first shaping mechanism 30, and it also has a shaping hole. The diameter of the shaping hole of the second shaping component 52 is smaller than the diameter of the shaping hole 331 of the first shaping mechanism 30. After the locking component 25 locks the stator after the first shaping, the second shaping component 52 uses the same method as the first shaping mechanism 30 to perform a second shaping on the stator. Since the diameter of the shaping hole of the second shaping component 52 is smaller than the diameter of the shaping hole 331 of the first shaping mechanism 30, the pin can be further corrected. At the same time, the shaping hole with a large diameter is first used and then the shaping hole with a small diameter is used, which can better shape some severely skewed pins, avoid directly using a small shaping hole, so that the severely skewed pins cannot be inserted into the shaping hole, and ensure the shaping effect and efficiency.

[0039] The suction component 53 includes a vertical moving component 531 arranged on the moving component 51, a shell 532 arranged on the vertical moving component 531, a connecting shaft 533 inserted on the shell 532, a buffer tray 534 arranged on the connecting shaft 533, a spring 535 sleeved on the connecting shaft 533, and a plurality of suction nozzles 536 arranged on the buffer tray 534.

[0040] The vertical moving assembly 531 is used to drive other components of the suction assembly 53 to move vertically so as to cover the PCB board on the pins. The vertical moving assembly 531 is composed of components such as a cylinder, a slide rail, and a slider, which should be existing technology and will not be repeated here.

[0041] The shell 532 is a cylindrical structure with a hollow interior. The shell 532 includes a hollow cylinder 5321, a top plate 5322 arranged at one end of the hollow cylinder 5321, and a bottom plate 5323 arranged at the other end of the hollow cylinder 5321. The top plate 5322 is connected to the vertical moving assembly 531, and the bottom plate 5323 is used to contact the PCB board. One end of the connecting shaft 533 is connected to the top plate 5322, and the other end is connected to the buffer plate 534. The spring 535 is used to play a buffering role when the suction nozzle 536 sucks. The suction nozzle 536 passes through the buffer plate 534 and the bottom plate 5323, and is used to suck the PCB board. When the suction nozzle 536 first sucks the PCB board on the material distribution component 40, and then the moving component 51 drives the suction component 53 to move above the stator, the vertical moving component 531 drives the PCB board down, so that the PCB board is mounted on the pins of the stator, thereby completing the assembly.

[0042] Compared with the prior art, the structure of the second shaping component 52 of the assembly device for assembling PCB and stator group provided by the present invention is the same as that of the first shaping mechanism 30, and also has a shaping hole, and the crooked pin will be squeezed by the inner wall of the shaping hole 331 and return to the right position. The diameter of the shaping hole of the second shaping component 52 is smaller than the diameter of the shaping hole 331 of the first shaping mechanism 30, and the pin is shaped twice, first using a large diameter shaping hole and then a small diameter shaping hole, which can better shape some severely crooked pins, avoid directly using a small shaping hole directly, resulting in the inability of severely crooked pins to be inserted into the shaping hole, and ensure the shaping effect and efficiency. The suction component 53 can absorb the PCB board, and then the moving component 51 drives the suction component 53 to move above the stator, and the vertical moving component 531 drives the suction component 53 to descend, so that the PCB board is sleeved on the pins of the stator, realizing the automated assembly of the entire process.

[0043] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
