Description

Technical Field

[0001] This application relates to the field of motor rotor processing technology, and in particular to a soldering device for motor rotor circuit boards. Background Technology

[0002] The rotor of an electric motor is the rotating component of the motor. An electric motor consists of two parts: the rotor and the stator. It is a device used to convert electrical energy into mechanical energy and vice versa.

[0003] Reference Figure 1 Typically, the structure of the motor rotor 02 includes various components such as the cylinder 01, rotor 02, circuit board 03, sponge gasket 04, magnetic metal end cap 05, and gear 06. The circuit board 03 has two soldering points 031. In order to achieve efficient production, a soldering device is needed to install the various components of the motor rotor 02.

[0004] Chinese Patent No. CN210451295U discloses a rotor soldering machine, which includes a frame. A slat conveyor is mounted on the frame. Above the slat conveyor, from left to right, are a terminal soldering device, a resistance detection device, and a flipping device. A pressure-sensitive ring feeding device is connected behind the flipping device, and a pressure-sensitive ring soldering device is located behind the pressure-sensitive ring feeding device. A slat return device is also mounted on the frame. This invention automatically transports the rotor via the slat conveyor, and then solders the rotor using the terminal soldering device and the pressure-sensitive ring soldering device, improving the rotor soldering efficiency, significantly reducing labor costs, achieving automated processing, and meeting the requirements of modern automation.

[0005] Regarding the aforementioned technologies, existing technologies utilize the cooperation of a varistor ring soldering device and a terminal soldering device to process motor rotor components. However, during the processes of the varistor ring soldering device, the terminal soldering device, and the rotor shaping device, it is necessary to contact or apply pressure to the rotor on the strip, which may cause the strip to move. This results in the processing station being unable to align the rotor components, making subsequent processing steps ineffective and reducing the processing efficiency of the rotor soldering machine. Summary of the Invention

[0006] In order to improve the processing efficiency of the soldering device for motor rotor circuit boards, this application provides a soldering device for motor rotor circuit boards.

[0007] The soldering device for motor rotor circuit boards provided in this application adopts the following technical solution: A soldering device for a motor rotor circuit board includes a body and a fixture plate. The body has a conveying channel, and several fixture plates are arranged within the conveying channel. A pushing component for pushing the fixture plates a predetermined distance is provided on the conveying channel. Along the conveying channel on the body, a soldering assembly for soldering the circuit board, a first pressing assembly for pressing an end cap, and a second pressing assembly for pressing a gear onto a cylinder output shaft are sequentially arranged. A limiting component is provided on the conveying channel at positions corresponding to the soldering assembly and the first pressing assembly. The limiting component includes a limiting cylinder, a mounting block, and a limiting block. A clearance groove is provided at the position of the first pressing assembly. Several placement holes are provided on the tooling plate. Restriction grooves are provided on both sides of the tooling plate at the positions corresponding to the placement holes. The mounting block is installed on one side of the conveying channel. The displacement limiting cylinder is installed on the mounting block. The limiting block is connected to the output shaft of the displacement limiting cylinder. When restricted, the limiting block moves between the limiting groove and the clearance groove. A transfer assembly for the transfer cylinder is provided on the machine body at the position corresponding to the second pressing assembly. A blowing assembly for conveying gaskets to the inside of the cylinder is provided on the conveying channel. The blowing assembly is located between the soldering assembly and the first pressing assembly.

[0008] By adopting the above technical solution, during processing, the circuit board is installed inside the cylinder, and the cylinder is placed on the placement hole of the tooling plate. Several cylinders correspond to one tooling plate, and several tooling plates are placed in the conveying channel. The tooling plates are pushed at equal intervals by the pushing component, and then the circuit board is soldered by the soldering component. The gaskets are conveyed one by one into the cylinder by the blowing component. The end cap is pressed onto the top of the cylinder by the first pressing component, and finally the gear is pressed onto the output shaft of the cylinder by the second pressing component. During this process, the limiting block is moved by the displacement cylinder, so that the limiting block is located between the clearance groove and the limiting groove to restrict the movement of the tooling plate, thus realizing the processing of the motor rotor. By setting the displacement limiting components at the positions of the soldering component and the first pressing component, it is ensured that the tooling plate will not move during processing, so that the soldering component and the first pressing component can be accurately aligned with the cylinder to perform the operation, and it is also ensured that subsequent processes will not fail, thereby improving the processing qualification rate of the motor rotor and improving the processing efficiency of the soldering device for the motor rotor circuit board.

[0009] Optionally, the pushing assembly includes a pushing cylinder, a connecting block, a pushing block, a return spring, and a stop block. The pushing cylinder is mounted on the conveying channel. The connecting block is connected to the output shaft of the pushing cylinder. The connecting block has a mounting groove. The pushing block slides vertically within the mounting groove. The pushing block has an abutting inclined surface. The thickness of the pushing block gradually decreases from bottom to top as the reference direction. Two stop blocks are connected on the conveying channel. The connecting block is located between the two stop blocks. A pushing groove is provided on the tooling plate at the position corresponding to each of the placement holes. When pushing, the pushing block abuts against the side wall of the pushing groove.

[0010] By adopting the above technical solution, when pushing, the pushing cylinder is activated to move the connecting block. At this time, the pushing block is kept in an upward state by the force of the reset spring, and the top end is located in the pushing groove. The movement of the pushing block drives the tooling plate to move until the connecting block touches the stop block to push the tooling plate a specified distance. When returning, the pushing block moves in the opposite direction, touches the inclined surface and touches the edge of the pushing groove, causing the pushing block to descend until the pushing block moves to the next pushing groove position, thereby achieving the effect of intermittently moving the tooling plate.

[0011] Optionally, two sets of soldering assemblies are arranged along the conveying channel. Each soldering assembly includes a first lifting cylinder, a transmission seat, a soldering gun, and solder wire. A soldering seat is connected to the machine body. The first lifting cylinder is vertically connected to the soldering seat. The transmission seat is vertically slidably fitted on the soldering seat and connected to the output shaft of the first lifting cylinder. A mounting seat is provided below the transmission seat. Several connecting columns are vertically connected to the mounting seat. The connecting columns pass through the transmission seat. A baffle is connected to the top of each connecting column. A buffer spring is sleeved on each connecting column. The buffer spring is located between the transmission seat and the mounting seat. The soldering gun is vertically mounted on the mounting seat and aligned with one of the soldering positions. The solder wire is disposed on one side of the soldering seat. A wire feeding assembly for driving the solder wire is provided on the soldering seat. The other set of soldering assemblies is aligned with another soldering position. An abutment block is provided on the soldering seat. The abutment block is located below the mounting seat. During soldering, the mounting seat abuts against the abutment block.

[0012] By adopting the above technical solution, during soldering, the first lifting cylinder is activated, causing the transmission base to descend, which in turn lowers the mounting base. The soldering torch and wire feeding assembly then descend until the mounting base contacts the contact block. At this point, the tip of the soldering torch contacts the soldering area of ​​the circuit board, and the wire feeding assembly delivers the solder wire, achieving the effect of soldering the circuit board. By incorporating connecting posts and buffer springs, the impact of the transmission base on the mounting base is buffered, reducing both the possibility of damage to the tip of the soldering torch and the possibility of the circuit board flipping due to the force exerted by the soldering torch tip.

[0013] Optionally, the wire feeding assembly includes a traction motor, a traction wheel, a feed hose, a clamping rod, a clamping screw, and a wire feeding seat. The solder wire is sleeved on the welding seat. The traction motor is mounted on the welding seat. The traction wheel is connected to the output shaft of the traction motor. An upper guide seat and a lower guide seat are connected to the welding seat. The traction wheel is located between the upper guide seat and the lower guide seat. One end of the clamping rod is rotatably connected to the welding seat. A clamping wheel is rotatably connected to the clamping rod. A nut is connected to the clamping screw. The clamping screw is threaded into the welding seat and abuts against the other end of the clamping rod. The wire feeding seat is detachably connected to the mounting seat. A feed hose is connected between the wire feeding seat and the lower guide seat. The outlet of the wire feeding seat faces the welding torch. The solder wire passes through the upper guide seat and the lower guide seat and abuts against the traction wheel and the clamping wheel. The solder wire passes through the feed hose and is led out from the outlet of the wire feeding seat.

[0014] By adopting the above technical solution, the clamping screw applies pressure to the clamping rod, causing the solder wire to rub against the clamping wheel and the traction wheel. When feeding the wire, the traction motor is started, causing the traction wheel to rotate. The friction force drives the solder wire to move. The solder wire is then conveyed to the end of the soldering gun through the guide of the conveying hose and the wire feeder, achieving the effect of automatic interval wire feeding.

[0015] Optionally, the first pressing assembly includes a first pressing cylinder, a lifting cylinder, a lifting seat, and a stamping seat. A fixed seat is connected to the machine body. The first pressing cylinder is installed on the top of the fixed seat. The lifting seat is vertically slidably fitted on the fixed seat. A fixed block is connected to the lifting seat. The fixed block is connected to the output shaft of the first pressing cylinder. The stamping seat is connected to the bottom wall of the lifting seat. A pressing ring is slidably fitted at the bottom of the stamping seat. A magnetic ring is connected to the pressing ring. A protective spring is connected between the stamping seat and the pressing ring. The lifting cylinder is installed on the fixed block. A magnetic block is connected to the output shaft of the lifting cylinder. The magnetic block is located inside the stamping seat. A conveying assembly is provided on the machine body to convey the end cap to the area directly below the pressing ring.

[0016] By adopting the above technical solution, during the pressing of the end cap, the end cap is conveyed to the area directly below the pressing cylinder via a conveying assembly. The lifting cylinder is then activated, causing the magnetic block to descend and attract the end cap. The end cap is then lifted, and as it passes the magnetic ring, it is intercepted and attracted by the ring, detaching from the magnetic block. The first pressing cylinder is then activated, causing the lifting seat and the pressing seat to descend, which in turn lowers the magnetic ring until the end cap is pressed onto the top of the cylinder, achieving the desired end cap pressing effect. By incorporating a buffer spring, the impact of the pressing seat on the cylinder is cushioned, reducing the possibility of damage to the cylinder.

[0017] Optionally, the conveying assembly includes a first vibratory plate, a gripping platform, a transfer platform, a conveying seat, and a conveying cylinder. The first vibratory plate and the conveying seat are both connected to the machine body, and a connecting seat is connected to the machine body. The gripping platform and the transfer platform are both connected to the connecting seat. The gripping platform is aligned with the output port of the first vibratory plate. A sliding seat is slidably fitted on the conveying seat, and a placement port is provided on the sliding seat. The conveying cylinder is mounted on the conveying seat, and its output end is connected to the sliding seat. The gripping platform, the transfer platform, and the placement port are all on a straight line and equidistant. The machine body is provided with a movable seat and a moving component that drives the movable seat to move. Two control cylinders are provided on the movable seat, and the output end of the control cylinder is connected to a gripper cylinder. The distance between the two gripper cylinders is the same as the distance between the gripping platform and the transfer platform.

[0018] By adopting the above technical solution, when conveying the end cap, the first vibratory feeder is started to convey the end cap to the clamping table. The moving part moves the moving seat, which drives the two gripper cylinders to move. The control cylinder is started, and the gripper cylinders descend to clamp the end cap at the clamping table and convey the end cap to the transfer table. Then, it continues to return to the initial position. Meanwhile, the other gripper cylinder moves the end cap at the transfer table to the placement port. The conveying cylinder is started to move the sliding seat until the end cap is moved directly below the stamping seat, thus achieving the effect of conveying the end cap.

[0019] Optionally, the machine body is provided with a transfer channel and a transposition assembly for conveying the cylinder to the transfer channel. The second pressing assembly includes a second vibratory plate, a transition seat, a moving cylinder, and a second pressing cylinder. The second vibratory plate is connected to the machine body, and the transition seat is connected to the transfer channel. The transition seat has a pushing groove, and the output port of the second vibratory plate is aligned with the pushing groove. A first push rod and a second push rod are slidably fitted in the pushing groove. The moving cylinder is connected to the end of the transition seat, and its output shaft is connected to the first push rod. The transition seat is connected to... A stop bar is connected to the second push rod, and a detection block is connected to the second push rod. The detection block is located outside the push groove and abuts against the stop bar. A return spring is connected between the end of the transition seat and the second push rod. A proximity sensor is connected to the transition seat and is located above the push groove. The second pressing cylinder is mounted on the machine body. A pressing column is connected to the output shaft of the second pressing cylinder. The pressing column is aligned with the push groove. A through hole is opened on the transition seat at the position corresponding to the pressing column. A conveying assembly is provided on the machine body to make the cylinder move at equal distances.

[0020] By adopting the above technical solution, during gear pressing, the cylinder is moved intermittently one by one using the transfer assembly. The second vibratory plate is activated, and the gears are conveyed one by one into the push groove. The moving cylinder is activated, causing the first push rod to move, which in turn drives the gear and the second push rod to move. At this time, the gear is confined between the first and second push rods, and the return spring is compressed until the detection block moves to the sensing end of the proximity sensor. The proximity sensor sends an electrical signal to the machine control system, which activates the second pressing cylinder, causing the pressing column to descend and push the gear to descend. The gear passes through the perforation and is pressed onto the output shaft of the cylinder, thus achieving the effect of pressing the gear.

[0021] Optionally, the transfer assembly includes a transfer seat, a first transfer plate, a second transfer plate, a first transfer cylinder, and a second transfer cylinder. The transfer seat is connected to the machine body. The first transfer plate is slidably fitted on the transfer seat, and its sliding direction is parallel to the transfer channel. The first transfer cylinder is mounted on the transfer seat, and its output shaft is connected to the first transfer plate. The second transfer plate is slidably fitted on the first transfer plate, and its sliding direction is perpendicular to the transfer channel. The second transfer plate is provided with a plurality of limiting grooves. The second transfer cylinder is connected to the first transfer plate, and its output shaft is connected to the second transfer plate. During transfer, the cylinder is located within the limiting grooves.

[0022] By adopting the above technical solution, when transferring the cylinder, the cylinder on the conveying channel is moved to the transfer channel by the switching component. The second transfer cylinder is activated to move the second transfer plate, and the cylinder enters the limiting transfer groove. The first transfer cylinder is activated to move the first transfer plate, which drives the second transfer plate and the cylinder to move, so that the cylinder is transferred to the pressing station of the second pressing component. In this way, the cylinders are transferred one by one, achieving the effect of transferring one by one and restricting the movement of the cylinder.

[0023] Optionally, the machine body is provided with a return channel parallel to the conveying channel. The machine body is provided with a transfer assembly, which includes a first transfer cylinder, a second transfer cylinder, and a return cylinder. A transition channel connects the end of the conveying channel and the end of the return channel. The first transfer cylinder and the second transfer cylinder are both mounted on the machine body. The output direction of the first transfer cylinder is parallel to the transition channel. The second transfer cylinder is vertically arranged, and a support plate is connected to its output shaft. The support plate is located at the end of the conveying channel. The return cylinder is mounted at the end of the return channel, and its conveying direction is parallel to the return channel.

[0024] By adopting the above technical solution, after the cylinder is repositioned, the empty tooling plate is pushed to the support plate by the tooling plate behind it. The second transfer cylinder is activated, and the support plate drives the tooling plate to descend. Then the first transfer cylinder is activated, and the tooling plate on the support plate is pushed into the transition channel. Subsequently, the tooling plates are pushed into the return channel one by one. The return cylinder is activated, and the tooling plate moves in the return channel. This process is repeated until the tooling plate is pushed to the filling station of the machine body, thus achieving the effect of automatically recovering the empty tooling plates.

[0025] Optionally, the blowing assembly includes a placement cylinder, a delivery pipe, a micro air pump, and a blowing block. A blowing seat is connected to the body, and the delivery pipe is connected to the blowing seat. The outlet end of the delivery pipe faces downward and is located directly above the cylinder. The placement cylinder is vertically connected to the delivery pipe and communicates with the interior of the delivery pipe. The inner diameter of the placement cylinder is larger than the outer diameter of the washer. A moving groove is opened on the delivery pipe at a position corresponding to the lower part of the placement cylinder. The blowing block is slidably fitted on the blowing seat and is partially located in the moving groove. The blowing block is hollow and has several blowing holes at positions corresponding to the interior of the delivery pipe. The micro air pump is mounted on the blowing seat and its output end is connected to a blowing pipe. The blowing pipe extends into the interior of the blowing block and is slidably fitted with the blowing block. An auxiliary spring is provided on the blowing seat, and the blowing block is located between the micro air pump and the auxiliary spring.

[0026] By adopting the above technical solution, the gaskets serve two purposes: buffering the impact on the circuit board and restricting its movement. However, the gaskets are soft and light, and due to friction and deformation, they cannot be transported one by one by vibration. Air pressure blowing is more reasonable. During transport, workers stack the gaskets inside the cylinder, with the bottom gasket falling into the conveying pipe. A micro air pump is activated, and air is blown into the blowing block through the air pipe. The blowing block moves under the influence of air pressure, impacting the bottom gasket and causing it to move. Simultaneously, air is ejected through the blowhole, acting on the gasket, which moves under pressure until it detaches from the conveying pipe and falls into the cylinder, achieving the effect of automatic positioning and conveying of the gaskets. First, the blowing block impacts the gasket, preventing the top gasket from falling, and then the gas pressure blows the gasket. The combined mechanical force and air pressure reduce the possibility of the gasket remaining inside the conveying pipe.

[0027] In summary, this application includes at least one of the following beneficial technical effects: 1. During processing, the circuit board is installed inside the cylinder, and the cylinder is placed on the placement holes of the tooling plate. Several cylinders correspond to one tooling plate. Several tooling plates are placed in the conveying channel, and the tooling plates are pushed at equal intervals by the pushing component. Then, the circuit board is soldered by the soldering component. The gaskets are conveyed one by one into the cylinder by the blowing component. The end cap is pressed onto the top of the cylinder by the first pressing component. Finally, the gear is pressed onto the output shaft of the cylinder by the second pressing component. During this process, the limiting block is moved by the displacement cylinder, so that the limiting block is located between the clearance groove and the limiting groove to restrict the movement of the tooling plate, thus realizing the processing of the motor rotor. By setting the displacement limiting components at the positions of the soldering component and the first pressing component, it is ensured that the tooling plate will not move during processing, so that the soldering component and the first pressing component can be accurately aligned with the cylinder to carry out the operation. It also ensures that subsequent processes will not fail, improves the processing qualification rate of the motor rotor, and improves the processing efficiency of the soldering device for the motor rotor circuit board. 2. During the pushing process, the pushing cylinder is activated to move the connecting block. At this time, the pushing block is kept in an upward state by the force of the return spring, and its top end is located in the pushing groove. The movement of the pushing block drives the tooling plate to move until the connecting block touches the stop block, thus pushing the tooling plate a specified distance. During the return process, the pushing block moves in the opposite direction, touching the inclined surface and then the edge of the pushing groove, causing the pushing block to descend until it moves to the next pushing groove position, thus achieving the effect of intermittently moving the tooling plate. 3. During soldering, the first lifting cylinder is activated, causing the transmission base to descend, which in turn lowers the mounting base. The soldering torch and wire feeding assembly then descend until the mounting base contacts the contact block. At this point, the tip of the soldering torch contacts the soldering area of ​​the circuit board, and the wire feeding assembly delivers the solder wire, achieving the soldering effect. By incorporating connecting posts and buffer springs, the impact of the transmission base on the mounting base is buffered, reducing the possibility of damage to the tip of the soldering torch and the likelihood of the circuit board flipping due to the force exerted by the soldering torch tip. 4. During gear pressing, the cylinder is moved intermittently by the transfer assembly. The second vibratory plate is started, and the gears are conveyed into the push groove one by one. The moving cylinder is started, which moves the first push rod, driving the gear and the second push rod to move. At this time, the gear is restricted between the first push rod and the second push rod, and the return spring is compressed until the detection block moves to the sensing end of the proximity sensor. The proximity sensor sends an electrical signal to the machine control system, which starts the second pressing cylinder, lowers the pressing column, pushes the gear down, and the gear passes through the perforation and is pressed onto the output shaft of the cylinder, thus achieving the effect of pressing the gear. 5. During conveying, workers stack the washers inside the cylinder, with the bottom washer falling into the conveying pipe. A miniature air pump is then activated, and air is blown into the conveying block through the air pipe. The conveying block moves under the air pressure, impacting the bottom washer and causing it to move. Simultaneously, air is ejected through the blowhole, acting on the washer, causing it to move under pressure until it detaches from the conveying pipe and falls back into the cylinder. This achieves the effect of automatically positioning and conveying the washer. First, the washer is impacted by the conveying block, preventing the top washer from falling. Then, the washer is conveyed by air pressure. This combination of mechanical force and air pressure reduces the possibility of the washer remaining inside the conveying pipe.

The micro air pump 43 is started, and air is blown into the blowing block 44. The blowing block 44 moves and hits the gasket 04, while preventing the upper gasket 04 from falling. At the same time, air is ejected from the blowing hole 441, blowing the gasket 04 again, causing the gasket 04 to come out of the conveying pipe 42 and fall into the cylinder 01, thus achieving the effect of conveying the gasket 04.

The movement of the gear 06 and the second push rod 632 causes the return spring 623 to be compressed, which in turn moves the detection block 6321 to the sensing end of the proximity sensor 624. The proximity sensor 624 sends an electrical signal to the control system of the machine body 1, which activates the second pressing cylinder 64. The pressing block descends, which in turn causes the pressing column 641 to descend, causing the gear 06 to descend and pass through the perforation, thus pressing the gear 06 onto the output shaft of the cylinder 01. The pressed cylinder 01 is then pushed into the discharge channel 161 and finally falls into the receiving box 162 to collect the motor rotor 02.

The first transfer cylinder 191 is activated, and the tooling plate 2 is moved into the transition channel 181. The tooling plates 2 are pushed into the return channel 18. The return cylinder 193 is activated to push the tooling plates 2 one by one to the operating table 13, so as to realize the effect of recycling the empty tooling plates 2 and reinstalling the cylinder 01.

[0077] The implementation principle of the soldering device for the motor rotor 02 circuit board 03 in this embodiment is as follows: During processing, the operator places the cylinder 01 in the placement hole 21 of the tooling plate 2, and installs the circuit board 03 inside the cylinder 01. The tooling plate 2 is placed in the placement channel 131. The initial feeding component pushes the tooling plate 2 to the discharge port of the placement channel 131. The transfer component 132 is activated to push the tooling plate 2 into the conveying channel 11. The pushing cylinder 121 is activated to move the connecting block 122, which in turn moves the pushing block 123. The pushing block 123 pushes the tooling plate 2 a quantitative distance until the cylinder 01 is directly below the soldering gun 33. The limiting cylinder 1111 is activated, and the limiting block 1113 moves into the limiting groove 23 to limit the movement of the tooling plate 2. The first lifting cylinder 31 lowers the mounting base 321 until it touches the contact block 322, causing the welding torch 33 to descend to one of the soldering positions 031. Simultaneously, the traction motor 71 is activated, causing the traction wheel 72 to rotate and move the solder wire 34, automatically feeding the wire to the end of the welding torch 33. After soldering one soldering position 031, the auxiliary pressure cylinder 141 is activated, causing the auxiliary pressure block 142 to descend and level the circuit board 03. After soldering the second soldering position 031 of the circuit board 03, the worker stacks the washers 04 into the placement cylinder 41 beforehand. The micro air pump 43 is activated, causing the blowing block 44 to move and strike the bottom washer 04. Gas is ejected from the blower, further agitating the washer 04, which is then transported into the cylinder 01. Subsequently, it is sensed by the infrared sensor 143. Check if washer 04 is inside cylinder 01, then use auxiliary pressure cylinder 141 to flatten washer 04. Then start the first vibratory feeder 81. Through the cooperation of the moving frame, control cylinder 151, and gripper cylinder 152, grab end caps 05 one by one and place them onto the placement port 842. Start the conveying cylinder 85 to move the sliding seat 841, moving the end cap 05 directly below the stamping seat 54. At this time, start the lifting cylinder 52 to lower the magnetic block 521 and attract the end cap 05. The end cap 05 rises and is intercepted by the magnetic ring 542, which attracts the end cap 05, causing it to detach from the magnetic block 521. Then start the first pressing cylinder 51, lowering the lifting seat 53. The stamping seat 54 presses the end cap 05 onto cylinder 01 to press the end cap 05. Then, use the rotating cylinder 172... Adjustment is performed so that the gripping cylinder 173 grips the cylinder 01 and flips it into the transfer channel 16. The second transfer cylinder 95 is activated, moving the second transfer plate 93. The cylinder 01 enters the limiting groove 931. The first transfer cylinder 94 is activated, moving the first transfer plate 92. The cylinder 01 is moved to directly below the perforation. The gears 06 are conveyed one by one into the pushing groove 621 via the second vibrating plate 61. The moving cylinder 63 is activated, moving the first push rod 631. This moves the gears 06 and the second push rod 632, causing the detection block 6321 to move to the sensing end of the proximity sensor 624. The proximity sensor 624 sends an electrical signal to the control system of the machine body 1, activating the second pressing cylinder 64. The pressing column 641 descends, causing the gears 06 to descend and pass through the perforation.With the press-fitted gear 06 in place, the motor rotor 02 finally enters the receiving box 162 through the discharge channel 161, thus completing the processing of the motor rotor 02. The empty tooling plate 2 moves onto the support plate 1921 and, through the cooperation of the second transfer cylinder 192 and the first transfer cylinder 191, enters the return channel 18. Then, the return cylinder 193 pushes the tooling plates 2 one by one onto the operating table 13, achieving the effect of automatically recovering the tooling plates 2 and repeatedly installing the cylinder 01.

[0078] By setting the limiting component 111 at the positions of the soldering component 3 and the first pressing component 5, it is ensured that the tooling plate 2 will not move during processing, so that the soldering component 3 and the first pressing component 5 can be accurately aligned with the cylinder 01 to carry out the operation, and it is also ensured that the subsequent process will not fail, thereby improving the processing qualification rate of the motor rotor 02 and improving the processing efficiency of the soldering device of the motor rotor 02 circuit board 03.
