[0002] The stator and rotor of a motor are important components of the motor. During the installation of the motor, the stator will be placed in the motor housing first, and then the motor rotor will be installed. However, during the installation process, the rotor is easily affected by the magnetic force of the stator, so manual installation is mostly used, and automated installation is more difficult.

[0003] After the motor rotor is installed, the motor carbon brush holder needs to be installed on the motor rotor. The motor carbon brush holder has two positions, namely a first position and a second position. In the first position, the carbon brush is in an elastic active state, which is also a normal working state. In the second position, the carbon brush is clamped and fixed with the carbon brush holder, which is convenient for installation on the rotor. When the carbon brush is installed on the motor, it is usually necessary to manually inspect the carbon brush. The carbon brush needs to be manually moved between the first position and the second position to confirm the state of the carbon brush, and then the carbon brush is installed on the motor rotor to achieve the installation of the carbon brush. However, in actual installation, the installation efficiency is low and the manual workload is large. Summary of the invention

[0061] A carbon brush holder detection line 400 is arranged between the carbon brush holder conveying line 200 and the motor housing conveying line 300, and a first carbon brush adjustment position 410 and a carbon brush detection position 420 are sequentially arranged along the conveying direction of the detection line, the first carbon brush adjustment position 410 is used to adjust the carbon brush in the carbon brush holder to move to the second position, and the carbon brush detection position 420 is used to detect the position of the carbon brush in the carbon brush holder;

[0062] The first carbon brush holder transfer device 500 is provided with a first carbon brush holder transfer part 510, and the first carbon brush holder transfer part 510 has a stroke of reciprocating motion between the carbon brush holder transfer position 210 and the carbon brush holder detection line 400, so as to transfer the carbon brush holder on the carbon brush holder transfer position 210 to the carbon brush holder detection line 400, and transport it to the first carbon brush adjustment position 410 through the carbon brush holder detection line 400;

[0064] The rotor transfer device 700 is provided with a rotor transfer part 710 . The rotor transfer part 710 has a stroke for reciprocating between the rotor transfer position 120 and the rotor installation position 310 to transfer the rotor on the rotor transfer position 120 to the rotor installation position 310 .

[0065] Specifically, before conveying the rotor to the rotor transfer position 120, the rotor conveyor line 100 inspects the rotor through the rotor inspection position 110. After the inspection, the rotor is moved to the rotor transfer position 120 and installed through the rotor transfer device 700 to be installed on the housing on the motor housing conveyor line 300, thereby realizing automated installation of the rotor. The rotor is inspected before installation to ensure that the rotor itself is free of faults, thereby improving the yield rate of electronic finished products.

[0066] After the carbon brush holder conveyor line 200 conveys the carbon brush holder to the carbon brush holder transfer position 210, the carbon brush holder is transferred to the carbon brush holder detection line 400 through the first transfer part on the first carbon brush holder transfer device 500, and the position of the carbon brushes in the carbon brush holder is adjusted so that the carbon brushes in the carbon brush holder are in the second position before installation, which facilitates the installation of the carbon brush holder on the rotor of the motor and realizes the automated installation of the carbon brushes.

[0067] Similarly, after the carbon brush holder passes through the first carbon brush adjustment position 410, it also needs to pass through the carbon brush detection position 420.

The first probe end 441 is arranged on one side of the transfer disk 430 and can correspond to a carbon brush holder placement position, and form a first carbon brush holder at this carbon brush holder placement position. Adjustment position 410, the first probe end 441 can be inserted into the carbon brush holder on the carbon brush holder placement position, and squeeze the carbon brush in the carbon brush holder outward to the second position, the first carbon brush holder detection device 450 is arranged behind the first probe device 440 along the rotation direction of the transfer disk 430, and the first carbon brush holder detection end 460 is provided on the first carbon brush holder detection device 450. The first carbon brush holder detection end 460 can squeeze the carbon brush located at the first position and avoid the carbon brush located at the second position to detect the position of the carbon brush in the carbon brush holder on the carbon brush holder placement position.

[0070] The first carbon brush holder detection end 460 of the first carbon brush holder detection device 450 can squeeze the carbon brush holder when the carbon brush is in the first position, so that the carbon brush holder is pushed by the first carbon brush holder detection end 460, and in the second position, the carbon brush holder can avoid being pushed by the first carbon brush holder detection end 460 or the distance pushed is less than the distance pushed when the carbon brush is in the first position, thereby realizing the detection of the carbon brush position in the carbon brush holder.

[0071] Reference Figure 1 , Figure 7 , Figure 8 and Fig. 9In some specific embodiments of the present invention, a first carbon brush holder fixing device 470 is provided at the corresponding position of the transfer disk 430 and the first probe device 440.

The first carbon brush holder fixing device 470 is provided with a first carbon brush holder extruding end, and the first carbon brush holder extruding end is used to squeeze the carbon brush holder on the carbon brush holder placement position.

[0072] Specifically, the first carbon brush holder fixing device 470 can pre-extrude the carbon brush holder located on the first carbon brush adjustment position 410 and pre-fix the carbon brush holder. When the first probe end 441 is inserted into the interior of the carbon brush holder, the fit between it and the carbon brush holder is tighter, making it easier for the first probe end 441 to squeeze the carbon brush in the carbon brush holder to the second position.

[0074] Among them, the carbon brush holder installation port is located at the bottom of the carbon brush holder, which is used to directly cover the rotor of the motor. The preset distance means that when the carbon brush is in the first position, the second carbon brush holder extrusion end will retract a certain distance. The specific value can be determined according to the actual force output by the first carbon brush holder detection end 460 and the elastic force exerted on the second carbon brush holder extrusion end.

When the carbon brush in the carbon brush holder is in the first position, the lifting end of the first carbon brush holder detection end 460 will abut against the carbon brush in the carbon brush holder, so that the carbon brush holder will reversely push the elastic second carbon brush holder extrusion end to shrink, thereby detecting that the carbon brush is in the first position; and when the carbon brush is in the second position, the extrusion detection end will not be affected by reverse pressure and shrink or the shrinkage distance is less than the shrinkage distance when the carbon brush is in the first position, so as to detect that the carbon brush is in the second position or the carbon brush is not installed, which does not meet the requirement that the carbon brush is in the first position, thereby realizing automatic detection of the carbon brush in the first position.

[0082] Specifically, by setting a carbon brush holder press-fitting position 330, the carbon brush holder is press-fitted so that the carbon brush holder is tightly fitted to the rotor. A carbon brush holder press-fitting device is provided on the carbon brush holder press-fitting position 330. The carbon brush holder press-fitting device includes a press-fitting part and a press-fitting driving part. The press-fitting part is located above the carbon brush holder press-fitting position 330 and is transmission-connected to the press-fitting driving part. Driven by the press-fitting driving part, the press-fitting part moves toward the carbon brush holder press-fitting position 330. The press-fitting part is shaped like the carbon brush holder on the motor housing on the side where the carbon brush holder press-fitting position 330 is located, so that the carbon brush holder can be better press-fitted onto the rotor.

[0083] Among them, a bearing installation position is provided on the side of the carbon brush holder away from the bearing, and a bearing conveying device and a bearing pre-installing device are provided on the bearing pre-installing position 340.

[0084] The bearing press-fitting position 350 is similar in structure to the carbon brush holder press-fitting position 330 and will not be described in detail herein. The bearing press-fitting position 350 is used to press the bearing onto the bearing mounting position of the carbon brush holder and to press the bearing.

[0085] Reference Fig.10 and Fig.11In some specific embodiments of the present invention, a second probe device 370 is provided on the motor housing conveyor line 300, and the second probe device 370 is located at the second carbon brush adjustment position 360. The second probe device 370 includes a second probe frame 371, a probe platform 372, a plurality of second probe positioning members 373, a plurality of second probe members 374, and a second probe driving member 375. The second probe frame 371 is arranged on one side of the motor housing conveyor line 300, and the second probe driving member 375 is arranged on the second probe frame 371. The probe platform 372 and the second probe The driving member 375 is connected in transmission and is arranged toward the second carbon brush adjustment position 360. It can move toward the second carbon brush adjustment position 360 under the drive of the second probe driving member 375. The second probe positioning member 373 and the second probe member 374 are arranged on the table surface of the probe platform 372 on the side facing the second carbon brush adjustment position 360. The second probe positioning member 373 is used to position the carbon brush holder on the second carbon brush adjustment position 360. The second probe member 374 is used to be inserted into the carbon brush holder on the second carbon brush adjustment position 360 and squeeze the carbon brush in the carbon brush holder to the first position.

[0086] Among them, the carbon brush holder is provided with a clamping block and a release port at the second position of the carbon brush. The release port is located at the top of the carbon brush holder and is arranged opposite to the installation port of the carbon brush holder. When the carbon brush is located at the second position, it will be engaged with the clamping block. When the carbon brush needs to be unlocked to the first position, the carbon brush can be pushed from the release port in the direction away from the clamping block, so that the carbon brush and the clamping block are misaligned up and down, thereby realizing the unlocking of the carbon brush from the second position and automatically rebounding to the first position.

[0087] The second probe driving member 375 may be a telescopic motor, the second probe positioning member 373 may be a positioning column, and the second probe member 374 may be a release column that can be inserted into the release port.

[0088] Specifically, when the carbon brush holder is located at the second carbon brush adjustment position 360, the carbon brush will be installed on the motor, and the second probe drive member 375 fixed on the second probe frame 371 will drive the probe platform 372 to move toward the carbon brush holder, and the second probe positioning member 373 will correspond to the carbon brush holder on the motor and squeeze the carbon brush holder on the motor to pre-fix the carbon brush holder on the motor, and the second probe member 374 will be inserted into the unlocking port at this time to separate the carbon brush from the card block, thereby unlocking the carbon brush and enabling the carbon brush to move from the second position to the first position, so as to automatically detect the position of the carbon brush and improve production efficiency.

[0089] Reference Fig.11 In some specific embodiments of the present invention, a carbon brush position detection device 331 is provided on the carbon brush holder press-fitting position 330, and the carbon brush position detection device 331 can emit light to the carbon brush located at the second position on the carbon brush holder to detect the position of the carbon brush in the carbon brush holder.

[0090] Specifically, by setting the carbon brush position detection device 331, after the carbon brush on the second carbon brush adjustment position 360 is moved to the first position, the carbon brush position detection device 331 can be an infrared detection device, and the infrared detection device includes an infrared transmitter and an infrared receiver. When the carbon brush is located at the second position, the light emitted by the infrared transmitter will be blocked to realize the detection of the carbon brush position, so as to ensure that the carbon brush is in the first position when it moves out of the second carbon brush adjustment position 360, so as to improve the accuracy of the installation of the carbon brush holder and improve the quality of automated production.

[0091] Although the first carbon brush holder detection device 450 has been set up before to detect the position of the carbon brushes in the carbon brush holder before installation, during the installation process, in order to avoid the carbon brushes not being in the second position due to collision between the carbon brushes and the rotor or other unexpected factors, multiple detections are performed to ensure that the carbon brushes are in the second position before installation and are still in the second position after installation, so that the produced motor has higher quality.

[0092] When there is no carbon brush in the carbon brush holder, the first carbon brush holder detection device 450 cannot detect it directly, and the carbon brush position detection device 331 can be used to perform another detection to ensure the position of the carbon brush in the carbon brush holder.

[0093] Reference Figure 2 , Figure 3 , Figure 4 and Figure 5 In some specific embodiments of the present invention, the rotor conveyor line 100 includes a rotor rotating conveyor belt 130, a plurality of rotor conveying platforms 140, a rotor positioning device 150 and a rotor detection device 160. The rotor conveying platform 140 is used to place the rotor. Each rotor conveying platform 140 is arranged on the rotor rotating conveyor belt 130 and is transmission-connected to the rotor rotating conveyor belt 130. It rotates under the drive of the rotor rotating conveyor belt 130. The rotor positioning device 150 is arranged on the rotor transfer position 120 to position the rotor conveying platform 140 on the rotor transfer position 120. The rotor detection device 160 is arranged on the rotor detection position 110 to detect the rotor on the rotor conveying platform 140.

[0094] Specifically, the rotor conveying platform 140 is circulated and conveyed by the rotor rotating conveyor belt 130, and there is no need to recycle the rotor conveying platform 140 after conveying, so the conveying efficiency is higher. During conveying, the rotor to be installed is inspected by the rotor detection device 160 to determine the quality of the rotor before installation. After determining that the rotor to be installed has no quality problems, the rotor is conveyed to the rotor transfer position 120 by the rotor conveying platform 140 and positioned by the rotor positioning device 150, so that the rotor on the rotor conveying platform 140 is aligned with the rotor transfer position 120, so as to facilitate the transfer of the rotor.

[0095] Among them, the rotor detection device 160 includes a displacement detector 161 and a detection telescopic member 162. The detection telescopic member 162 is transmission-connected to the displacement detector 161. The displacement detector 161 is arranged toward the rotor rotary conveyor belt 130. Driven by the detection telescopic member 162, the displacement detector 161 moves toward the rotor rotary conveyor belt 130 to squeeze the rotating shaft of the rotor, and the detection end of the displacement detector 161 moves a preset distance.

[0096] Specifically, during rotor detection, the rotor displacement detector 161 will move toward the rotor driven by the rotor detection telescopic member 162 and abut against the rotor's shaft. The length of the rotor's shaft will push the detection end of the rotor displacement detector 161 to move a certain distance. The moving distance at the detection end is the same as the length of the rotor's shaft, and the preset distance can be the pre-set length of the shaft. The moving distance of the detection end is compared with the preset distance to detect whether the rotor's shaft meets the standard.

[0097] Among them, the rotor positioning device 150 includes a rotor infrared positioning device 151 and a rotor blocking arm 152. The rotor blocking arm 152 extends to the rotor rotary conveyor belt 130 and is offset from the rotor conveying platform 140. It can allow the rotor conveying platform 140 to pass through, but can block the rotor conveying platform 140 with the rotor. The rotor infrared positioning device 151 is set on the rotor mounting position 310 to detect the position of the rotor relative to the rotor mounting position 310.

[0098] Specifically, by setting the rotor blocking arm 152, after the rotor conveying platform 140 with the rotor is conveyed to the position of the rotor blocking arm 152, it will be blocked by the rotor blocking arm 152, and the rotor on the rotor conveying platform 140 will be further positioned by the rotor infrared positioning device 151, and after the rotor is detected, an electrical signal is sent to the rotor rotating conveyor belt 130 to pause the rotor rotating conveyor belt 130, and after the rotor is taken away by the rotor transfer device 700, an electrical signal can be sent to the rotor rotating conveyor belt 130, so that the rotor rotating conveyor belt 130 continues to convey the rotor conveying platform 140, thereby realizing the automatic detection and transportation of the rotor.

[0099] Reference Figure 1 and Figure 2 In some specific embodiments of the present invention, a rotor loading position 131 for loading materials is further provided on the rotor rotary conveyor belt 130 , and the rotor loading position 131 is arranged in front of the rotor detection position 110 along the conveying direction.

[0100] Specifically, the rotor is placed on the rotor conveying platform 140 at the rotor loading position 131 to achieve the installation of the rotor, and the rotor can be placed on the rotor conveying platform 140 manually to achieve the loading of the rotor, so as to facilitate the subsequent automatic installation of the rotor.

[0101] Reference Figure 1 and Figure 2 In some specific embodiments of the present invention, a rotor guide plate 132 is provided between the rotor upper material position 131 and the rotor detection position 110, and a rotor guide groove is provided on the rotor guide plate 132, and the rotor guide groove can only allow the rotor to pass through.

[0102] Specifically, by providing the rotor guide plate 132, after the rotor is loaded, the position of the rotor is adjusted and detected through the rotor guide groove on the rotor guide plate 132 to prevent the rotor from being offset on the rotor conveying platform 140 due to human error during the installation process. The rotor guide groove is used to correct the rotating shaft of the rotor on the rotor conveying platform 140, so that the rotating shaft of the rotor on the rotor conveying platform 140 will not be deflected, which is more convenient for subsequent processing.

[0103] Reference Figure 5 and Figure 6 In some specific embodiments of the present invention, a rotor mounting platform 311 is provided on the rotor mounting position 310, a rotor mounting hole 3111 is provided on the rotor mounting platform 311, a rotor guide ring platform 3112 is provided on the side of the rotor mounting hole 3111 facing the shell conveying device, the rotor guide ring platform 3112 can be inserted into the shell, and is provided with a rotor guide hole for the rotor to pass through.

[0104] Specifically, when the rotor is installed in the housing, a stator is usually placed in advance in the housing. If the rotor is directly inserted into the housing and the positioning is inaccurate, the rotor will interfere with the stator, resulting in installation errors and affecting normal installation.

[0105] A rotor guide ring 3112 is provided on the rotor mounting hole 3111 of the rotor mounting platform 311. The diameter of the rotor guide hole of the rotor guide ring 3112 may be less than or equal to the diameter of the circle formed between the two stators, but the rotor can pass through the rotor guide hole. Furthermore, the rotor is positioned and guided by the rotor mounting platform 311 provided outside the housing, so that the rotor is more easily aligned with the rotor mounting platform 311 and can be smoothly inserted into the rotor guide hole to enter the housing from the rotor guide hole, thereby avoiding interference caused by collision between the rotor and the stator, making the automated installation smoother and reducing the probability of failure.

[0106] Reference Figure 5 and Figure 6 In some specific embodiments of the present invention, a rotor ejection device 312 is further provided on the rotor mounting position 310. The rotor ejection device 312 is arranged on a side of the shell conveying device away from the rotor mounting platform 311. The rotor ejection device 312 is arranged toward the rotor mounting platform 311 and can be aligned with the shell on the rotor mounting position 310 to squeeze the shell until it is engaged with the rotor guide ring platform 3112.

[0107] Specifically, when in use, the rotor ejection device 312 ejects the housing on the motor housing conveyor line 300 until it abuts against the rotor mounting platform 311, and the opening of the housing will be engaged with the rotor guide ring 3112. At this time, the rotor guide ring 3112 is aligned with the stator in the housing, which facilitates the guidance of the rotor installation process to achieve automated installation of the rotor.

Driven by the first carbon brush holder transfer driving member 550, the two first carbon brush holder clamping plates 560 move in opposite directions to clamp or release the carbon brush holder.

[0113] Specifically, when clamping the carbon brush holder on the carbon brush holder transfer position 210, the carbon brush holder clamping position between the two first carbon brush holder clamps 560 is first moved above the carbon brush holder transfer position 210 through the first carbon brush holder transverse reciprocating moving device 530, and the carbon brush holder clamping position is moved toward the carbon brush holder on the carbon brush holder transfer position 210 through the first carbon brush holder vertical reciprocating moving device 540. When moving to the point where the carbon brush holder can be clamped, the two first carbon brush holder clamps 560 move toward each other driven by the first carbon brush holder transfer driving member 550 to clamp the carbon brush holder on the carbon brush holder transfer position 210. After clamping, the two first carbon brush holder clamps 560 move upward through the first carbon brush holder vertical reciprocating moving device 540, and are moved to the carbon brush holder placement position of the carbon brush holder detection line 400 driven by the first carbon brush holder transverse reciprocating moving device 530, thereby realizing the transfer of the carbon brush holder and realizing automated transfer with higher work efficiency.

[0114] The second carbon brush holder transfer device 600 includes a second carbon brush holder transfer frame, a second carbon brush holder transverse reciprocating moving device, a second carbon brush holder vertical reciprocating moving device, a second carbon brush holder transfer driving member and two oppositely arranged second carbon brush holder clamps.

Driven by the second carbon brush holder transverse reciprocating moving device, the second carbon brush holder reciprocates from the carbon brush detection position 420 to the carbon brush holder installation position 320. The second carbon brush holder transfer driving member is arranged on the second carbon brush holder vertical reciprocating moving device. Driven by the second carbon brush holder vertical reciprocating moving device, the second carbon brush holder transfer driving member reciprocates vertically.
