Abstract
Description
Technical Field
[0001] This utility model relates to the field of product surface cleaning technology, specifically to a cleaning device for a fully automatic rotor armature spot welding test integrated machine. Background Technology
[0002] The fully automatic rotor armature spot welding and testing machine is an automated device that integrates coil winding, commutator assembly, welding, and electrical testing. It achieves efficient rotor production through servo drive, vision positioning, and data closed-loop control. The assembly process of the coil and commutator in this equipment is as follows: After stamping, plating, and injection molding of the insulation groove, the commutator is positioned to the assembly station by a robotic arm. The pre-wound coil wire is embedded into the commutator copper strip groove through a high-precision fixture, followed by resistance welding or laser welding.
[0003] However, commutator surfaces are prone to leaving metal debris, oxides, and insulation residues during processing and transportation. Existing technologies rely on manual wiping or fixed brush cleaning, which has the following drawbacks: 1. Incomplete cleaning: Microscopic contaminants (such as dust in dead corners of the tank) lead to a welding failure rate as high as 3%-5%, and increased contact resistance affects conductivity; 2. Insufficient efficiency and compatibility: Traditional cleaning methods cannot be adapted to high-speed production lines (>300 pieces / hour) and are difficult to be compatible with commutators of different sizes; 3. Lack of process control: The lack of a real-time surface cleanliness detection module makes it impossible to dynamically adjust cleaning parameters, limiting the improvement of yield. Utility Model Content
[0004] This invention addresses the problem that impurities on the commutator surface can cause assembly problems with the coil during commutator assembly. It provides a cleaning device for a fully automatic rotor armature spot welding and testing machine that can clean the commutator surface before assembly, thus preventing the assembly between the commutator and the coil from being affected.
[0005] The technical solution adopted in this utility model is:
[0006] A cleaning device for a fully automatic rotor armature spot welding test integrated machine is provided, comprising:
[0007] A support block has a receiving groove at its top and a first air inlet on its outer wall. A first transition cavity communicating with the first air inlet is formed inside the side wall of the support block. Multiple first air outlets communicating with the first transition cavity are formed on the inner wall of the support block within the receiving groove. A housing is located on the outer wall of the support block, and a first pump body is located inside the housing. A first air inlet pipe connects the air outlet of the first pump body to the first air inlet. Multiple support rods are arranged perpendicular to the top of the support block, and each support rod is located inside the receiving groove. A support ring is provided on the outer wall of each support rod, and each support ring coincides with the central axis of each corresponding support rod. A gap exists between each support ring and the inner bottom of the support block.
[0008] Optionally, the bottom of the support block is provided with a second transition cavity, and the inner bottom of the support block located in the receiving groove is provided with multiple second air outlets connected to the second transition cavity. The outer wall of the support block is provided with a second air inlet connected to the multiple second transition cavities. The top of the support block is also provided with multiple uprights located inside the receiving groove. The horizontal distance from the central axis of each upright to the central axis of the four adjacent support rods is equal. The interior of each upright is provided with a third transition cavity, and the outer wall of each upright is provided with multiple exhaust ports connected to the third transition cavity in a circumferential direction. The third transition cavity of each upright is connected to the second transition cavity. The interior of the housing is also provided with a second pump body, and a second air inlet pipe is connected between the second pump body and the air inlet.
[0009] Optionally, a support net is provided on the inner wall surface of the support block within the receiving groove. The support net consists of multiple connecting rods arranged interlaced with each other. Each support rod is located at the top of the support net, and each upright rod passes through the support net.
[0010] Optionally, a cover plate is hinged to the top of the support block to seal the receiving groove.
[0011] Optionally, a fourth transition cavity is provided inside the cover plate, a third air inlet communicating with the fourth transition cavity is provided on the outer wall of the cover plate, and a third air outlet communicating with the fourth transition cavity is provided on the end face of the cover plate facing the receiving groove; a third pump body is also provided inside the box body, and a third air inlet pipe is connected between the air outlet of the second pump body and the third air inlet of the cover plate.

[0015] The beneficial effects of this utility model are:
[0016] Before the commutator is assembled, it is clamped and fixed to multiple support rods located in the receiving groove of the support block through the hollow part inside the circulator. After the commutator is placed on the support rods, it will be placed on top of the support ring located on the outer wall of the support rod. That is, the support ring plays the role of the commutator. When the commutator is on the support rod, the first pump located inside the housing is activated. The first pump pumps gas through the first air inlet pipe to the first air inlet on the outer wall of the support block. The gas then enters the first transition chamber connected to the first air inlet. After passing through the first transition chamber, the gas is discharged from the first air outlet. Since the first air outlet is located on the inner wall of the support block in the receiving groove, and the commutator is located on the support rod in the receiving groove, the gas blown out by the first air outlet can clean the commutator in the receiving groove, thereby removing impurities on the surface of the commutator. After the impurities on the surface of the commutator are cleaned, the commutator can be removed from the receiving groove and installed with the coil. Attached Figure Description

[0030] The following disclosure provides many different embodiments or examples for implementing various structures of this invention. To simplify the disclosure, specific examples of components and arrangements are described below. Of course, these are merely examples and are not intended to limit the scope of this invention.
[0031] The embodiments of the utility model will now be described in detail with reference to the accompanying drawings.
[0032] Example
[0033] Please see Figure 1-6As shown, this embodiment discloses a cleaning device for a fully automatic rotor armature spot welding test integrated machine, including a support block 1. A receiving groove 10 is formed on the top of the support block 1, which is used to place the commutator that needs to be cleaned. A first transition cavity 11 is formed on the side wall of the support block 1, located inside the side wall. The first transition cavity 11 is used for gas entry. The gas entry is achieved by forming a first air inlet 12 on the outer wall of the support block 1. The first air inlet 12 is connected to a first air inlet pipe 21. The other end of the first air inlet pipe 21 is connected to the air outlet of a first pump body 20, that is, the first pump body 20 can pump gas into the interior of the first transition cavity 11 through the first air inlet pipe 21. The gas inside the first transition cavity 11 needs to be discharged into the receiving tank 10 to clean the commutator. Multiple first air outlets 13 are opened on the inner wall of the support block 1 inside the receiving tank 10. The multiple first air outlets 13 are all connected to the first transition cavity 11. That is, the gas inside the first transition cavity 11 is blown out through the multiple first air outlets 13 to clean the commutator inside the receiving tank 10 and blow away the impurities attached to the surface of the commutator.
[0034] Furthermore, multiple support rods 14 are provided on the inner bottom of the support block 1 within the receiving groove 10. Adjacent support rods 14 are evenly spaced, and each support rod 14 is positioned on the support block 1 with its central axis perpendicular to the inner bottom of the support block 1. A support ring 15 is circumferentially provided on the outer wall of each support rod 14. When the commutator is placed into the receiving groove 10, the hollow portion in the middle of the commutator allows the support rod 14 to pass through, thus limiting the commutator's movement. The support ring 15 on each support rod 14 then supports the commutator, ensuring it is positioned at the air outlet 13 on the inner wall of the support block 1 within the receiving groove 10, achieving a better cleaning effect. It is worth noting that the support rings 15 on adjacent support rods 14 do not contact each other; that is, there is a gap between adjacent support rings 15. This prevents poor cleaning of impurities on the commutator surface due to a small gap between the commutators.
[0035] Furthermore, a second transition cavity 17 is formed inside the support block 1 at its bottom, and multiple second air outlets 19 are formed on the inner bottom surface of the support block 1 within the receiving groove 10. Each second air outlet 19 is connected to the second transition cavity 17. A second air inlet 18 is also formed on the outer wall of the support block 1, which is connected to the second transition cavity 17. A second air inlet pipe 23 is connected to the second air inlet 18, and the other end of the second air inlet pipe 23 is connected to a second pump body 22. The second pump body 22 is located inside the housing 2. By operating the second pump body 22, the second pump body 22 pumps gas into the second transition cavity 17 through the second air inlet pipe 23. The gas in the second transition cavity 17 is then discharged through the second air outlet 19, which can clean the bottom of the commutator located in the receiving groove 10 by blowing air.
[0036] Multiple uprights 3 are vertically arranged on the inner bottom of the support block 1 within the receiving groove 10. The horizontal distance between the central axis of each upright 3 and the central axes of the four adjacent support rods 14 is equal. That is, when viewed from the top of the support block 1 towards its inner bottom, the central axes of the four adjacent support rods 14 are connected to form a square, and the central axis of the upright 3 is located at the center of this square. A third transition cavity 30 is opened inside each upright 3, and multiple exhaust ports 31 are circumferentially opened on the outer wall of each upright 3. Each exhaust port 31 is connected to the third transition cavity 30. The third transition cavity 30 inside each upright 3 is connected to each second air outlet 19 at the inner bottom of the support block 1 located in the receiving groove 10. That is, the number of uprights 3 is the same as the number of second air outlets 19. The central axis of each upright 3 is the same as the central axis of each corresponding second air outlet 19. The outer diameter of the upright 3 is larger than the diameter of the second air outlet 19 to cover the second air outlet 19. Specifically, after the second pump body 22 is started, the second pump body 22 pumps the gas into the interior of the second transition cavity 17 through the second air inlet pipe 23. The gas then enters the second air outlet 19 through the second transition cavity 17 and is discharged. The discharged gas enters the third transition cavity 30 inside the upright 3 and is finally discharged through the exhaust port 31 on the side wall of the upright 3. The discharged gas can blow and clean the commutator surface that cannot be reached by the first air outlet 13.
[0037] A support net 16 is provided on the inner wall surface of the support block 1 located in the receiving groove 10. The support net 16 is specifically composed of multiple connecting rods, which are interlaced to form a mesh structure. Multiple support rods 14 located in the receiving groove 10 are provided on the outer wall surface of the connecting rods in the support net 16. Multiple upright rods 3 are connected to the inner bottom of the support block 1 through the support net 16.
[0038] A cover plate 4 is hinged to the top of the support block 1. The cover plate 4 can seal the receiving groove 10. In actual use, it can prevent impurities on the commutator surface in the receiving groove 10 from being blown out of the support block 1 by gas during the cleaning process, so as to prevent the surrounding environment from being polluted and deteriorated.
[0039] Furthermore, a fourth transition cavity 40 is formed inside the cover plate 4, and a third air inlet 41 connected to the fourth transition cavity 40 is formed on the outer wall of the cover plate 4. A third air inlet pipe 25 is connected to the third air inlet 41, and the other end of the third air inlet pipe 25 is connected to a third pump body 24, which is located inside the housing 2. A third air outlet connected to the fourth transition cavity 40 is formed on the end face of the cover plate 4 facing the inner groove 10 of the support block 1. When the third pump body 24 is started, it pumps gas into the third transition cavity 30 through the third air inlet pipe 25, and then the gas is discharged through the third air outlet. It is worth noting that the operation of the third pump body 24 is premised on the cover plate 4 covering the top of the support block 1. At this time, the gas discharged through the third air outlet can blow the top of the commutator, achieving a multi-faceted cleaning effect.
[0040] The central axis of each first air outlet 13 and each exhaust outlet 31 is inclined towards the inner bottom of the support block 1. That is, the gas blown out by each first air outlet 13 and each exhaust outlet 31 is directed towards the inner bottom of the support block 1, which can blow impurities blown off the commutator surface into the collection box for collection. In order to prevent impurities blown off the commutator surface from adhering to the connecting rod and the top of the support ring 15 in the support mesh 16, the top of the support ring 15 is set as a slope, and the connecting rod is a round rod, which can prevent impurities from adhering to the surface of the support ring 15 and the connecting rod. In addition, a sealing gasket is provided on the closed surface of the cover plate 4 facing the outer top of the support block 1, which can prevent impurities in the receiving groove 10 from being blown out to the outside of the support block 1 and affecting the surrounding environment.
[0041] Finally, it should be noted that the above are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Without conflict, the embodiments and features described in the embodiments of this application can be arbitrarily combined with each other. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
