Description

Technical Field

[0001] The invention relates to automatic assembly equipment of a brush plate assembly for a brushed motor, belonging to the technical field of motor development. Background Art

[0002] A brushed motor is a rotating motor that contains a brush device to convert electrical energy into mechanical energy (motor) or mechanical energy into electrical energy (generator). Brushed motors are the basis of all motors. They have the characteristics of fast starting, timely braking, smooth speed regulation over a wide range, and relatively simple control circuits.

[0003] Most brushed DC motors consist of three main sub-components: the stator, brush holder end caps, and rotor. The stator consists of a central and cylindrical two-pole permanent magnet, an iron core that supports the bearings, and a steel tube that closes the magnetic circuit; the brush holder end caps are made of plastic material. Depending on the intended use of the motor, brushes can be of two different types; carbon or multi-wire. The carbon type uses copper graphite or silver graphite, which is ideal for incremental motion applications that require high continuous torque and peak torque; the multi-wire type uses precious metals, which ensures low starting voltage and higher efficiency, making it a perfect match for portable battery-powered applications. When in use, a brushed DC motor has coils wound in the rotor. The coils are surrounded by magnets contained in the stator. The two ends of the coils are connected to the commutator, which in turn is connected to electrodes called brushes. As long as the brushes and commutator are in contact, direct current will flow through the brushes and coils.

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the present invention.

[0027] Reference Figure 1-Figure 5, the present invention provides an automatic assembly device for a brush plate assembly of a brushed motor, including a rotary feeding mechanism 1, a transplanting mechanism 2, a tray 3, a positioning tooling 4 and a tray conveying mechanism 5. The rotary feeding mechanism 1 is placed on one side of the tray conveying mechanism 5 for synchronous feeding and replenishment of the brush plate assembly to be assembled. The tray 3 is placed on the tray conveying mechanism 5 for receiving and conveying the brush plate assembly to be assembled to the motor assembly station. The positioning tooling 4 is installed on the tray 3 to receive and fix the brush plate assembly to be assembled. The transplanting mechanism 2 is placed above the tray conveying mechanism 5 for grasping and assembling the brush plate assembly to be assembled on the rotary feeding mechanism 1 onto the positioning tooling 4 on the tray 3, and for assembling the motor and the brush plate assembly when the tray 3 is sent to the motor assembly station. In this embodiment, the tray conveying mechanism 5 is preferably a chain tray conveying mechanism 5 with a vacant middle part, which is a prior art and will not be elaborated too much. The tray 3 is preferably two.

[0028] Referring to Figure 2-4 , the transplanting mechanism 2 includes a mounting frame 21, a linear transplanting module 22, a hanging frame 23, a limiting component 24, a wire harness gripper 25, a brush plate gripper 26 and a pressing cylinder 27. The mounting frame 21 is in an inverted "U" shape and two are spaced apart and mounted. The tray conveying mechanism 5 passes through the two mounting frames 21. The linear transplanting module 22 is installed on the top wall of any one of the mounting frames 21, and the limiting component 24 is installed on the top wall of the other mounting frame 21. The hanging frame 23 is slidably arranged above the two mounting frames 21 through the linear transplanting module 22 and the limiting component 24. In this embodiment, the linear transplanting module 22 is a linear module, which is a prior art and will not be elaborated too much. One end of the hanging frame 23 is fixed to the slider of the linear transplanting module 22 by bolts, and the other end is slidably connected to the mounting frame 21 through the limiting component 24. The wire harness gripper 25 and the brush plate gripper 26 are installed on the hanging frame 23 for grasping the brush plate assembly to be assembled on the rotary feeding mechanism 1, and the pressing cylinder 27 is installed on the hanging frame 23 for pressing the grasped brush plate assembly to be assembled onto the positioning tooling 4 on the tray 3.

[0029] Further, the limiting component 24 includes a limiting block 241 and a guide rail 242. The limiting block 241 is welded and fixed to the bottom wall of the hanging frame 23, and the guide rail 242 is fixedly installed on the top wall of the mounting frame 21 by bolts. The limiting block 241 is slidably matched with the guide rail 242. When carrying out the assembly work, the linear transplanting module 22 drives the hanging frame 23 to reciprocally slide above the rotary feeding mechanism 1 and the tray conveying mechanism 5. The setting of the limiting component 24 can ensure the stability of the movement of the hanging frame 23, and then through the wire harness gripper 25, the brush plate gripper 26 and the pressing cylinder 27, the operation of grasping the brush plate assembly to be assembled on the rotary feeding mechanism 1 and pressing it onto the tray 3 is realized, ensuring the grasping and feeding efficiency.

[0030] Referring to Figure 2-Figure 4The transplanting mechanism 2 also includes a motor assembly component 28, which is installed in two groups and is respectively arranged on the opposite side walls of the two mounting frames 21 for assembling the motor and the brush plate assembly.

[0031] Furthermore, the motor assembly component 28 includes a fixed plate 281, a moving cylinder 282, a fixed seat 283, a lifting cylinder 284 and a pneumatic clamp 285. The fixed plate 281 is welded and fixed on the side wall of the mounting frame 21. The moving cylinder 282 is mounted on the fixed plate 281. The fixed seat 283 is driven by the moving cylinder 282 to slide and is installed on the fixed plate 281. The fixed plate 281 is installed with a slide rail that limits the sliding of the fixed seat 283 and ensures the stability of the sliding. The sliding direction of the fixed seat 283 is the same as the sliding direction of the hanger 23. The lifting cylinder 284 is installed on the fixed seat 283. The pneumatic clamp 285 is driven by the lifting cylinder 284 to be lifted and set on the fixed seat 283 to grasp the motor to be assembled. When the brush plate assembly to be assembled is sent to the assembly station, the lifting cylinder 284 is started to drive the motor and the brush plate assembly to engage for assembly.

[0032] Furthermore, a limit buffer 6 is installed on the side of the fixed plate 281 away from the moving cylinder 282. The limit buffer 6 is used to limit the maximum moving distance of the fixed seat 283. At the same time, the buffering effect can be activated when pushing to ensure the overall service life of the motor assembly component 28.

[0033] Reference Figure 2 In a further embodiment, a lifting and positioning mechanism 7 is installed at the bottom of the pallet conveying mechanism 5 located below the press-fitting cylinder 27. The lifting and positioning mechanism 7 is used to lift the pallet 3 from the pallet conveying mechanism 5 to facilitate the press-fitting of the brush plate assembly to be assembled that is grabbed from the rotating feeding mechanism 1. In this embodiment, the structure of the lifting and positioning mechanism 7 is similar to the "A pallet positioning and lifting device" with announcement number CN212145211U, which is a prior art and will not be elaborated on. It is only necessary to lift the pallet 3 to a fixed position under the pallet conveying mechanism 5, and it can also be replaced by other lifting and positioning mechanisms 7.

[0034] Reference Figure 3 and Figure 5 The rotary feeding mechanism 1 includes a base 11, a driving member 12, a rotating seat 13 and a buffer fixture 14. The rotating seat 13 is driven and rotated on the base 11 by the driving member 12. Two buffer fixtures 14 are installed and are arranged on the upper surfaces of the two opposite sides of the rotating seat 13. The installation directions of the two buffer fixtures 14 are opposite, and two brush plate assemblies to be assembled can be installed on each buffer fixture 14. In this embodiment, the driving member 12 can be a reduction motor or a rotary cylinder. In this embodiment, the driving member 12 is preferably a reduction motor. The driving member 12 is installed on the base 11, and the rotating seat 13 is fixedly connected to the output shaft of the driving member 12;

[0035] Two brush plate assemblies to be assembled are installed on each cache tooling 14. When in use, the transfer mechanism 2 first presses one brush plate assembly to be assembled onto the tray 3 close to the motor assembly station. At the same time, the idle cache tooling 14 on the rotating feeding mechanism 1 replenishes the materials of the brush plate assembly to be assembled, and the tray 3 loaded with materials enters the assembly station for the next step of assembly. The transfer mechanism 2 then presses another brush plate assembly to be assembled into the second tray 3. At this time, the idle cache tooling 14 also realizes the replenishment of two materials, thereby greatly improving the assembly efficiency.
