Description

Technical Field

[0001] The invention relates to the technical field of stator potting, and more specifically, to a potting device for a multi-station servo motor stator assembly. Background Art

[0002] A servo motor is a high-precision electric motor that can achieve precise position, speed or torque control through a closed-loop control system; it is widely used in fields that require precise motion control, such as robots, CNC machine tools, automation equipment, etc.

[0003] The stator assembly is one of the core components of the servo motor, which directly affects the performance, efficiency and control accuracy of the motor. At the same time, the potting of the stator assembly is also a key process in motor manufacturing. The stator winding and core are encapsulated with insulating materials (such as epoxy resin, polyurethane or silicone) to improve their mechanical strength, insulation performance, heat dissipation capacity and environmental protection level.

[0004] In the prior art, before potting the stator assembly, it is necessary to select epoxy resin, polyurethane or silicone according to needs, then pre-treat the stator (remove oil and dust), and finally perform a vacuum potting operation. Pressurized injection is performed in a vacuum environment to ensure bubble-free filling, thereby achieving the potting of the stator assembly.

[0005] However, during the potting process, some potting mechanisms, in order to avoid the generation of bubbles caused by pouring glue from top to bottom, will allow the resin to slide along the surface of the core shaft during the potting process. This will cause resin to remain on the core shaft, and the resin will also solidify simultaneously with the resin on the surface of the stator assembly, which will cause the resin on the surface of the stator assembly and the core shaft to be pulled out synchronously during the process of extracting the core shaft, resulting in incompleteness of the solidified resin on the stator surface, thereby reducing the potting quality and being unfavorable for the potting effect. For this reason, a potting device for a stator assembly of a multi-station servo motor is proposed to improve the existing problems. Summary of the invention

DETAILED DESCRIPTION

[0032] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0033] See also Figure 1-Figure 12 , the present invention provides the following technical solutions: Example 1, see Figure 1-Figure 12 A potting device for a multi-station servo motor stator assembly includes a potting mechanism 1, two ends of the potting mechanism 1 are symmetrically provided with pre-cutting mechanisms 2, and a defense mechanism 3 is symmetrically provided on the pre-cutting mechanism 2 in a radial N direction.

[0034] Among them, the function of the pre-cutting mechanism 2 is to first pre-cut the resin between the surface of the stator component and the surface of the core shaft in the horizontal direction, and then pre-cut in the vertical direction around the surface of the core shaft, so that the resin fixed between the core shaft and the stator component is completely separated, thereby avoiding that some potting mechanisms, in order to avoid the generation of bubbles caused by potting from top to bottom, will allow the resin to slide along the surface of the core shaft during the potting, which will cause resin to remain on the core shaft, and the resin will also solidify at the same time as the resin on the surface of the stator component, resulting in the resin on the surface of the stator component and the core shaft being pulled out simultaneously during the process of extracting the core shaft, causing the solidified resin on the stator surface to be incomplete, thereby improving the potting quality and further improving the potting effect.

[0035] The main purpose of the defense mechanism 3 is to fence the surface of the core shaft to prevent resin fragments on the surface from falling into the motor housing at any time during the extraction process of the core shaft, causing the holes in the motor housing to be blocked, thereby ensuring the unobstructed holes in the motor housing and improving the assembly quality and production reliability of the servo motor.

[0036] See also Figure 1-Figure 2 Specifically, the potting mechanism 1 includes a potting platform 11, a vertical plate 12 symmetrically arranged on the top of the potting platform 11 in a radial N direction, an X-axis horizontal electric linear guide 13 arranged between the vertical plates 12, a vertical electric linear guide 14 symmetrically arranged on the X-axis horizontal electric linear guide 13 in a radial N direction, a lifting plate 15 arranged on the vertical electric linear guide 14, and a potting gun 16 arranged on one side of the lifting plate 15; the top of the potting platform 11 is also symmetrically provided with a Y-axis horizontal electric linear guide 17 in a radial N direction, and a carrying plate 18 is arranged on the Y-axis horizontal electric linear guide 17, and the carrying plate 18 is located below the corresponding potting gun 16.

[0037] Among them, before potting, two or more stator assemblies are placed on the corresponding supporting plate 18. Then, on the one hand, the Y-axis horizontal electric linear guide 17 is started, driving the corresponding supporting plate 18 and the stator assembly to slide, and move to the bottom of the potting gun 16; on the other hand, the corresponding X-axis horizontal electric linear guide 13 is also started, driving the corresponding vertical electric linear guide 14, the lifting plate 15 and the potting gun 16 to move, and slide to the top of the corresponding stator assembly; finally, the vertical electric linear guide 14 is started to drive the potting gun 16 to move downward and be located between the stator assembly and the core shaft to facilitate glue potting.

[0038] It should be noted that the lead screw inside the X-axis horizontal electric linear guide 13 is a bidirectional lead screw, which can drive the corresponding vertical electric linear guides 14 to move closer to or away from each other.

[0039] See also Figure 3-Figure 6 Specifically, the pre-cutting mechanism 2 includes a base frame 21, a fixed seat 22 arranged on the top of the base frame 21, a flip cylinder 23 rotatably connected to the fixed seat 22, a flip table 24 rotatably connected to the telescopic end of the flip cylinder 23, an annular slide rail 25 symmetrically arranged on one side of the flip table 24 in the radial N direction, an electric ring block 26 evenly sliding on the annular slide rail 25, and a pre-cut piece 27 arranged on the side of the electric ring block 26 away from the annular slide rail 25.

[0040] Among them, the flip cylinder 23 is started, and its telescopic end pushes the flip table 24 to rotate, so that the flip table 24 can be changed from a vertical direction to a horizontal direction. During this process, the corresponding core shaft will pass through the center of the corresponding annular slide rail 25. Subsequently, the electric ring block 26 is started, driving the corresponding pre-cut piece 27 to pre-cut the resin between the surface of the stator component and the surface of the core shaft in the horizontal direction, thereby achieving the purpose of preliminary cutting; thereafter, the pre-cut piece 27 is started, and the electric ring block 26 is started again, and then the circumference of the core shaft surface is pre-cut in the vertical direction, so that the resin fixed between the core shaft and the stator component is completely separated, thereby avoiding that some potting mechanisms, in order to avoid the generation of bubbles caused by the glue pouring from top to bottom, will allow the resin to slip along the surface of the core shaft during the glue pouring, then there will be resin residue on the core shaft, and the resin will also solidify at the same time as the resin on the surface of the stator component, which will cause the resin on the surface of the stator component and the core shaft to be pulled out synchronously during the process of extracting the core shaft, so that the resin on the stator surface after solidification is incomplete, thereby improving the potting quality and further improving the potting effect.

[0041] It should be noted that, in the initial state of the pre-cut piece 27, the pre-cut ends thereof are cut in a horizontal distribution.

[0042] See also Figure 7-Figure 12Specifically, the defense mechanism 3 includes ear plates 31 evenly arranged on the side of the flip table 24 away from the annular slide rail 25, a fixing ring 32 arranged between the ear plates 31, a fixing bar 33 arranged on the outer wall of the fixing ring 32, a driving motor 34 arranged at the end of the fixing bar 33 away from the fixing ring 32, a main defense component 35 symmetrically arranged at the output end of the driving motor 34 in the radial N direction, and a secondary defense component 36 arranged on one side of the main defense component 35.

[0043] Among them, the driving motor 34 is started, driving one of the main defense parts 35 to rotate, so that the other main defense part 35 can rotate synchronously, and then the two main defense parts 35 can be folded close to each other. In this process, the two auxiliary defense parts 36 will also rotate with the corresponding main defense parts 35, and fold and deform, so that the two main defense parts 35 and the two auxiliary defense parts 36 rotate in the circumferential direction at the same time and shrink and fold; it should be noted that when the two main defense parts 35 and the two auxiliary defense parts 36 are unfolded and not folded in a plane, the driving motor 34 can be driven in reverse, thereby achieving the purpose of fencing the surface of the core shaft, avoiding the problem that resin fragments on the surface of the core shaft will fall into the motor housing at any time during the extraction process, causing the holes in the motor housing to be blocked, thereby ensuring the smooth flow of the holes in the motor housing and improving the assembly quality and production reliability of the servo motor.

[0044] See also Figure 1-Figure 3 Furthermore, the top of the base frame 21 is U-shaped, the turning platform 24 is located inside the base frame 21, and one end of the turning platform 24 is rotatably connected to the inner wall of the base frame 21; a lifting cylinder 211 is symmetrically arranged below the base frame 21, and the telescopic end of the lifting cylinder 211 is connected to the inner wall of the base frame 21.

[0045] When the lifting cylinder 211 is started, the telescopic end of the lifting cylinder 211 can drive the base frame 21 and all the mechanisms on the base frame 21 to synchronously move upward or downward, thereby achieving the purpose of lifting.

[0046] See also Figure 4-Figure 6 Furthermore, through holes 241 are symmetrically opened on the side wall of the flip table 24 in the radial N direction, and the inner diameter of the annular slide rail 25 can be concentrically distributed with the corresponding through hole 241; a linear slide rail 261 is also arranged on the side wall of the electric ring block 26 away from the annular slide rail 25, and an electric slider 262 is slidably arranged on the linear slide rail 261, and the side of the electric slider 262 away from the linear slide rail 261 is connected to the pre-cut piece 27, and the linear slide rail 261 and the corresponding electric ring block 26 are vertically distributed.

[0047] In the process of the turning table 24 changing from a vertical state to a horizontal state, the corresponding through hole 241 will be aligned with the corresponding stator assembly.

[0048] By starting the electric slider 262 , the corresponding pre-cut pieces 27 can be driven to slide along the opening direction of the linear slide rail 261 , so that the three pre-cut pieces 27 can be moved closer to the core shaft or away from the core shaft.

[0049] See also Figure 4-Figure 6 Furthermore, the pre-cut piece 27 includes a connecting plate 271, a telescopic cylinder 272 arranged on one side of the connecting plate 271, a telescopic block 273 arranged at the telescopic end of the telescopic cylinder 272, a stretching bar 274 rotatably connected to the telescopic block 273 on a side away from the telescopic cylinder 272, a rotating block 275 rotatably connected to an end of the stretching bar 274 away from the telescopic block 273, and a pre-cutter 276 arranged at an end of the rotating block 275 away from the stretching bar 274; the side wall of the connecting plate 271 away from the telescopic cylinder 272 is connected to a side of the electric slider 262 away from the linear slide rail 261, the connecting plate 271 is arranged in the same direction as the corresponding linear slide rail 261, the rotating block 275 is L-shaped, and the middle part of the side wall of the rotating block 275 is rotatably connected to the side of the connecting plate 271 away from the electric slider 262.

[0050] Among them, if it is necessary to pre-cut the resin between the surface of the stator component and the surface of the core shaft in the horizontal direction, the telescopic cylinder 272 is started, and its telescopic end pushes the telescopic block 273 to extend, so that the telescopic block 273 pushes the stretching bar 274 and the rotating block 275, thereby causing the rotating block 275 to rotate, so that the vertical state is changed to a horizontal state. At this time, the pre-cutter 276 is also horizontally distributed, and then the electric ring block 26 is started, driving the corresponding pre-cutter 276 to pre-cut the resin between the surface of the stator component and the surface of the core shaft in the horizontal direction, thereby achieving the purpose of preliminary cutting.

[0051] If it is necessary to perform vertical pre-cutting around the surface of the core shaft in a circular manner, the telescopic end of the telescopic cylinder 272 can be retracted. At this time, the pre-cutting knife 276 is vertically distributed. Then the electric ring block 26 is started, driving the corresponding pre-cutting knife 276 to perform vertical pre-cutting around the surface of the core shaft in a circular manner, so that the resin fixed between the core shaft and the stator assembly is completely separated, thereby avoiding that some potting mechanisms, in order to avoid the generation of bubbles caused by potting from top to bottom, will allow the resin to slide along the surface of the core shaft during the potting process, which will result in resin residue on the core shaft, and the resin will also solidify at the same time as the resin on the surface of the stator assembly, resulting in the resin on the surface of the stator assembly and the core shaft being pulled out synchronously during the process of extracting the core shaft, causing the solidified resin on the stator surface to be incomplete, thereby improving the potting quality and further improving the potting effect.

[0052] It should be noted that during the process of adjusting the angle of the pre-cut piece 27, the lifting cylinder 211 will also be started, driving the base frame 21 and all the mechanisms located on the base frame 21 to synchronously rise or fall, thereby avoiding the pre-cut piece 27 from scratching the stator assembly and the core shaft during rotation, and ensuring smooth adjustment.

[0053] Embodiment 2: Through the technical solution of embodiment 1, the problem that some potting mechanisms in the prior art allow the resin to slide along the surface of the core shaft during the potting process in order to avoid the generation of bubbles caused by the potting from top to bottom is solved, which will result in the resin remaining on the core shaft, and the resin will also solidify at the same time as the resin on the surface of the stator assembly, which will cause the resin on the surface of the stator assembly and the core shaft to be pulled out synchronously during the process of extracting the core shaft, so that the resin on the surface of the stator assembly will be incomplete after solidification. However, it still does not solve the problem that in the process of extracting the core shaft, some solidified resin fragments will still fall into the motor housing, causing the holes in the motor housing to be blocked; for this reason, the following solution is proposed: See also Figure 7-Figure 12 Furthermore, the ear plate 31 and the fixing bar 33 are both L-shaped, and one end of the ear plate 31 away from the fixing ring 32 is connected to the side wall of the flip table 24 away from the annular slide rail 25, and a ring groove 321 is provided on the side of the fixing ring 32 away from the ear plate 31.

[0054] The main defense parts 35 are oppositely distributed, and the main defense parts 35 include a first main tooth 351, a second main tooth 352 arranged on one side of the first main tooth 351, and a first main board 353 arranged between the first main tooth 351 and the second main tooth 352; the first main board 353 is fan-shaped, and the output end of the drive motor 34 passes through the side wall of the fixed bar 33 and is connected to one of the first main teeth 351, one of the first main teeth 351 can be meshed with the other first main tooth 351 for transmission, and the side wall of the other first main tooth 351 is rotatably connected to the side wall of the fixed bar 33.

[0055] After the resin between the core shaft and the stator assembly is cut by the pre-cutting mechanism 2, the lifting cylinder 211 is started, driving the base frame 21 and all the mechanisms located on the base frame 21 to synchronously rise or fall. At this time, the turning table 24 is synchronously lowered, so that the corresponding stator assembly enters the corresponding defense mechanism 3 through the corresponding through hole 241. At this time, the defense mechanism is started again to fence the surface of the core shaft.

[0056] It should be noted that the core shaft will be pulled out for a certain distance first and then enter the defense mechanism 3. At this time, the defense mechanism 3 is located below the resin fragments on the surface of the core shaft.

[0057] Among them, the driving motor 34 is started, driving one of the first main teeth 351 to rotate, so that one of the first main boards 353 and the second main tooth 352 can be flipped synchronously. Since one of the first main teeth 351 is engaged with the other first main tooth 351, the other first main tooth 351 can also rotate synchronously, and drive the other first main board 353 and the second main tooth 352 to flip synchronously, so that the two first main boards 353 are folded close to each other, thereby achieving the purpose of folding the two main defense parts 35 with each other.
