Description

Technical Field

[0001] The invention relates to the technical field of iron core manufacturing, and in particular to a variable beat collaborative control component of a drive motor rotor iron core shaping production line. Background Art

[0002] The rotor core of the drive motor used in the car is made of stacked silicon steel sheets (punched sheets). Silicon steel sheets are usually punched on a punch press using a progressive die. In order to achieve the integrated operation of punching and stacking silicon steel sheets, in addition to the punching die (progressive die), the punch press is usually also equipped with an automatic stacking die for silicon steel sheets. After the silicon steel sheets are stamped, the punched sheets enter the stacking die for automatic stacking, thus forming the core.

[0003] However, the drive motor rotor core manufactured by the above method actually still has the following problems: after the drive motor rotor core is stacked, the overlap between two adjacent silicon steel sheets is not tight, resulting in a large positive height deviation of the drive motor rotor core. On the one hand, the loose overlap will cause the drive motor rotor core to generate noise during operation and reduce the magnetic properties of the core.

[0004] To this end, a drive motor rotor core shaping production line has been developed, which can shape the drive motor rotor core after stacking to eliminate or reduce the gap between adjacent punching sheets inside the drive motor rotor core, thereby ultimately improving the performance of the drive motor rotor core. The entire drive motor rotor core shaping production line realizes integrated operations from loading to shaping and testing, thereby improving the production efficiency of the drive motor rotor core shaping operation.

[0005] In order to improve the production efficiency of the drive motor rotor core shaping production line, the shaping production line is directly connected to the punching machine used to realize the integration of punching and stacking, so that the drive motor rotor core output from the punching machine can automatically enter the shaping production line. However, since the position of the drive motor rotor core dropped from the punching machine on the belt conveyor is somewhat random, the distance between two adjacent drive motor rotor cores dropped on the belt conveyor is also randomly changed, which brings certain technical difficulties to the synchronous beat control with high reliability requirements on the shaping production line. Summary of the invention

[0006] In order to solve the above problems, the present invention proposes a variable beat coordinated control component for driving a motor rotor core shaping production line, aiming to achieve high-reliability variable beat coordinated control of the shaping production line. The specific technical solution is as follows:

[0007] A variable beat collaborative control component for a drive motor rotor core shaping production line comprises a belt conveyor, an angle servo motor arranged on one side of the belt conveyor, and a beat control dial arranged on the motor shaft of the angle servo motor, wherein the motor shaft of the angle servo motor is arranged vertically upward, and the beat control dial comprises a fan-shaped shifting block vertically fixed to the upper end of the motor shaft for shifting the outer circle of the drive motor rotor core from the rear to the front in the forward direction of the drive motor rotor core, and a cantilever baffle bar arranged on the fan-shaped shifting block away from the arc outer edge position of the fan-shaped shifting block for blocking the forward movement of the outer circle of the drive motor rotor core from the front in the forward direction of the drive motor rotor core; an infrared detector pointing to the side opposite to the fan-shaped shifting block is arranged at a position on the other side of the belt conveyor opposite to the beat control dial, and the angle servo motor, the infrared detector and the belt conveyor are respectively connected to a PLC controller.

[0008] In the present invention, the fan-shaped shift block and the cantilever baffle are arranged with equal thickness in the up and down directions, and the lower end surface heights of the fan-shaped shift block and the cantilever baffle are higher than the conveying table height of the belt conveyor and lower than the upper end surface height of the rotor core of the driving motor on the belt conveyor.

[0009] In the present invention, when the beat control dial is in the initial position, the fan-shaped dial block on the beat control dial is located outside the belt conveyor, and the cantilever baffle on the beat control dial enters the upper position inside the belt conveyor.

[0010] In the present invention, the rhythm control dial is located on one side close to the discharging end of the belt conveyor.

[0011] In order to further improve the reliability of the transfer of the drive motor rotor core on the shaping production line, a further improvement scheme is: a drive motor rotor core positioner is arranged at the discharge end of the belt conveyor, and the drive motor rotor core positioner includes a pair of guide blocks arranged on both sides of the discharge end of the belt conveyor and a positioning block arranged at the end of the discharge end of the belt conveyor. The space between the pair of guide blocks forms a guide channel for the drive motor rotor core to move forward. The guide channel is formed by connecting a section of a straight channel and a section of a trumpet-shaped contraction channel. The section of the trumpet-shaped contraction channel is located at the rear side of the forward direction of the drive motor rotor core, and the section of the trumpet-shaped contraction channel gradually contracts toward the forward direction of the drive motor rotor core. The section of the straight channel is located at the front side of the forward direction of the drive motor rotor core, and a fitting gap is provided between the straight channel and the outer circle of the drive motor rotor core for the drive motor rotor core to pass through.

[0012] Preferably, the beat control dial is a nylon dial, and the guide block is a nylon guide block.

[0013] In the present invention, a material taking robot for taking away the drive motor rotor core located in the drive motor rotor core positioner and transporting it to the next workstation is arranged at a side position in front of the discharge end of the belt conveyor. The material taking robot is movably arranged on a guide rail and connected to the PLC controller.

[0014] In the present invention, a belt discharging conveyor connected to the discharging part of the punching machine is arranged at the feeding end of the belt conveyor, and the belt conveyor and the belt discharging conveyor are arranged perpendicular to each other, and the conveying table of the belt discharging conveyor is arranged to be inclined downward in the direction of the belt conveyor.

[0015] In the present invention, an iron core discharging deceleration buffer device is arranged at the iron core output position of the driving motor rotor of the belt-type discharging conveyor, and the iron core discharging deceleration buffer device includes a left-side arc-shaped elastic baffle arranged at the left position above the iron core output position of the belt-type discharging conveyor, and a right-side arc-shaped elastic baffle arranged at the right position above the iron core output position of the belt-type discharging conveyor, an arc-shaped discharging channel for iron core output is formed between the left-side arc-shaped elastic baffle and the right-side arc-shaped elastic baffle, and the arc-shaped discharging channel is transitionally connected to the feeding end of the belt conveyor.

[0016] By setting an arc-shaped discharge channel on the belt-type discharge conveyor, the online connection between the core shaping production line and the punching machine is realized, thereby realizing the integrated continuous operation of core punching, stacking and shaping, thereby further improving the efficiency of core production.

[0017] As a further improvement of the present invention, a drive motor rotor core positioning absorber is arranged on the positioning block, and the drive motor rotor core positioning absorber includes an arc positioning surface arranged on the positioning block and adapted to the outer circle of the drive motor rotor core, and a groove is opened on the arc positioning surface along the circumference of the arc positioning surface. The positioning block is also provided with a negative pressure pipeline connected to the groove space on the arc positioning surface, and the negative pressure pipeline is connected to the vacuum generator.

[0018] The working principle of the present invention is as follows:

[0019] The stacked drive motor rotor core output from the punch press falls from the output port of the punch press onto the belt-type discharging conveyor, and after being touched by the elastic buffer of the side wall of the arc-shaped discharging channel on the belt-type discharging conveyor, it enters a random position at the feeding end of the belt conveyor through the arc-shaped discharging channel. Then, the belt conveyor conveys the drive motor rotor core that falls on the belt conveyor forward in an intermittent movement manner. When the drive motor rotor core is transported to the position between the beat control dial and the infrared detector, the drive motor rotor core is detected by the infrared detector. At this time, the angle servo motor moves, driving the beat control dial to rotate a certain angle at a set speed. Under the movement of the fan-shaped dial of the beat control dial, the drive motor rotor core is quickly pushed into the drive motor rotor core positioner and is reliably sucked by the drive motor rotor core positioning absorber set on the positioning block using negative pressure. At this time, the drive motor rotor core in the drive motor rotor core positioner can be accurately taken away by the material taking manipulator and transported to the next shaping station.

[0020] In the present invention, since the outer edge of the fan-shaped block on the beat control dial is a cylindrical surface, when the driving motor rotor core located between the fan-shaped block and the infrared detector is turned, the driving motor rotor core at the rear of the belt conveyor can be separated and prevented from moving forward at the same time, until the fan-shaped block completes a turning cycle and rotates back to the original position, the driving motor rotor core at the rear is allowed to enter the position between the fan-shaped block and the infrared detector, thereby starting the turning operation of the next beat. In this process, the material picking beat of the picking manipulator and the turning beat of the beat control dial are synchronized by setting a fixed time difference.

[0021] From the above working principle of the variable beat collaborative control component, it can be known that although the position of the driving motor rotor core falling on the belt conveyor is random, the distance between two adjacent driving motor rotor cores falling on the belt conveyor is also variable, resulting in the time interval between the two front and rear dialing cycles of the beat control dial also changing, but because the material picking beat of the material picking robot and the dialing beat of the beat control dial are synchronized by setting a fixed time difference, the continuous synchronous shaping operation of the driving motor rotor core shaping production line is realized under the variable rhythm (or called variable beat) condition.

[0022] The beneficial effects of the present invention are as follows: the specially designed rhythm control dial structure and shape can cooperate with the infrared detector, the drive motor rotor core positioner and the material picking robot to achieve high-reliability variable rhythm coordinated control of the shaping production line.

DETAILED DESCRIPTION

[0026] The specific implementation of the present invention is further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0027] like Figures 1 to 2 The figure shows an embodiment of a variable beat cooperative control component of a driving motor rotor core shaping production line of the present invention, comprising a belt conveyor 2, an angle servo motor 3 arranged on one side of the belt conveyor 2, and a beat control dial 4 arranged on the motor shaft of the angle servo motor 3, the motor shaft of the angle servo motor 3 is arranged vertically upward, the beat control dial 4 comprises a fan-shaped shifting block 5 vertically fixed to the upper end of the motor shaft for shifting the outer circle of the driving motor rotor core 1 from the rear to the front in the forward direction of the driving motor rotor core 1, a cantilever baffle 6 arranged on the fan-shaped shifting block 5 away from the arc outer edge position of the fan-shaped shifting block 5 for blocking the forward movement of the outer circle of the driving motor rotor core 1 from the front in the forward direction of the driving motor rotor core 1, an infrared detector 7 pointing to the side opposite to the fan-shaped shifting block 5 is arranged at the other side of the belt conveyor 2 at a position corresponding to the beat control dial 4, and the angle servo motor 3, the infrared detector 7 and the belt conveyor 2 are respectively connected to a PLC controller.

[0028] In this embodiment, the fan-shaped shift block 5 and the cantilever baffle 6 are arranged with equal thickness in the up and down directions, and the lower end surface heights of the fan-shaped shift block 5 and the cantilever baffle 6 are higher than the conveying table height of the belt conveyor 2 and lower than the upper end surface height of the driving motor rotor core 1 on the belt conveyor 2.

[0029] In this embodiment, when the beat control dial 4 is in the initial position, the fan-shaped dial block 5 on the beat control dial 4 is located outside the belt conveyor 2, and the cantilever baffle 6 on the beat control dial 4 enters the upper position inside the belt conveyor 2.

[0030] In this embodiment, the rhythm control dial 4 is located on one side close to the discharge end 8 of the belt conveyor 2 .

[0031] In order to further improve the reliability of the transfer of the drive motor rotor core 1 on the shaping production line, a further improvement scheme is: a drive motor rotor core positioner 9 is arranged at the discharge end 8 of the belt conveyor 2, and the drive motor rotor core positioner 9 includes a pair of guide blocks 10 arranged on both sides of the discharge end 8 of the belt conveyor 2, and a positioning block 11 arranged at the end of the discharge end 8 of the belt conveyor 2. The space between the pair of guide blocks 10 forms a guide channel 12 for the drive motor rotor core 1 to move forward. The guide channel 12 is formed by connecting a section of a straight channel 13 and a section of a trumpet-shaped contraction channel 14. The section of the trumpet-shaped contraction channel 14 is located at the rear side of the forward direction of the drive motor rotor core 1, and the section of the trumpet-shaped contraction channel 14 gradually contracts toward the forward direction of the drive motor rotor core 1. The section of the straight channel 13 is located at the front side of the forward direction of the drive motor rotor core 1, and a matching gap is set between the straight channel 13 and the outer circle of the drive motor rotor core 1 for the drive motor rotor core 1 to pass through.

[0032] Preferably, the beat control dial 4 is a nylon dial, and the guide block 10 is a nylon guide block.

[0033] In this embodiment, a material picking robot 15 is provided at a side position in front of the discharge end 8 of the belt conveyor 2 for taking away the drive motor rotor core 1 located in the drive motor rotor core positioner 9 and transporting it to the next workstation. The material picking robot 15 is movably arranged on the guide rail 27 and connected to the PLC controller.

[0034] In this embodiment, the feed end 16 of the belt conveyor 2 is provided with a belt discharging conveyor 17 connected to the discharging part of the punch press 28, and the belt conveyor 2 and the belt discharging conveyor 17 are arranged perpendicular to each other, and the conveying table of the belt discharging conveyor 17 is arranged downwardly inclined in the direction of the belt conveyor 2.

[0035] In this embodiment, a core discharging deceleration buffer device 18 is provided at the output position of the driving motor rotor core 1 located at the belt-type discharging conveyor 17, and the core discharging deceleration buffer device 18 includes a left-side arc-shaped elastic baffle 19 arranged at the left position above the core output position of the belt-type discharging conveyor 17, and a right-side arc-shaped elastic baffle 20 arranged at the right position above the core output position of the belt-type discharging conveyor 17. An arc-shaped discharging channel 21 for core output is formed between the left-side arc-shaped elastic baffle 19 and the right-side arc-shaped elastic baffle 20, and the arc-shaped discharging channel 21 is transitionally connected to the feed end 16 of the belt conveyor 2.

[0036] By providing an arc-shaped discharge channel 21 on the belt-type discharge conveyor 17, the core shaping production line is connected online with the punch press 28, thereby realizing the integrated continuous operation of core punching, stacking and shaping, thereby further improving the efficiency of core production.

[0037] As a further improvement of this embodiment, a drive motor rotor core positioning absorber 22 is arranged on the positioning block 11, and the drive motor rotor core positioning absorber 22 includes an arc positioning surface 23 arranged on the positioning block 11 and adapted to the outer circle of the drive motor rotor core 1, and a groove 24 is opened on the arc positioning surface 23 along the circumference of the arc positioning surface 23. The positioning block 11 is also provided with a negative pressure pipeline 25 connected to the space of the groove 24 on the arc positioning surface 23, and the negative pressure pipeline 25 is connected to a vacuum generator 26.

[0038] The working principle of this embodiment is as follows:

[0039] The stacked drive motor rotor core 1 output from the punch press 28 falls from the output port of the punch press 28 onto the belt discharge conveyor 17 , and after being touched by the elastic buffer of the side wall of the arc-shaped discharge channel 21 on the belt discharge conveyor 17 , enters a random position of the feed end 16 of the belt conveyor 2 through the arc-shaped discharge channel 21 . Then, the belt conveyor 2 conveys the drive motor rotor core 1 that falls on the belt conveyor 2 forward in an intermittent moving manner. When the drive motor rotor core 1 is conveyed to the position between the beat control dial 4 and the infrared detector 7, the drive motor rotor core 1 is detected by the infrared detector 7. At this time, the angle servo motor 3 is activated to drive the beat control dial 4 to rotate a certain angle at a set speed. Under the movement of the fan-shaped dial 5 of the beat control dial 4, the drive motor rotor core 1 is quickly pushed into the drive motor rotor core positioner 9 and is reliably sucked by the drive motor rotor core positioning absorber 22 arranged on the positioning stopper 11 using negative pressure. At this time, the drive motor rotor core 1 in the drive motor rotor core positioner 9 can be accurately taken away by the material taking robot 15 and transported to the next shaping station.

[0040] In this embodiment, since the outer edge of the fan-shaped block 5 on the beat control dial 4 is a cylindrical surface, when the drive motor rotor core 1 between the fan-shaped block 5 and the infrared detector 7 is turned, the drive motor rotor core 1 behind the belt conveyor 2 can be separated and prevented from moving forward at the same time, until the fan-shaped block 5 completes a turning cycle and rotates back to the original position, the drive motor rotor core 1 behind is allowed to enter the position between the fan-shaped block 5 and the infrared detector 7, thereby starting the next beat turning operation. In this process, the material picking beat of the material picking manipulator 15 and the turning beat of the beat control dial 4 are synchronized by setting a fixed time difference.

[0041] From the above working principle of the variable beat collaborative control component, it can be known that although the position where the driving motor rotor core 1 falls on the belt conveyor 2 is random, and the distance between two adjacent driving motor rotor cores 1 falling on the belt conveyor 2 is also variable, resulting in the time interval between the two front and rear dialing cycles of the beat control dial 4 also changing, but because the material picking beat of the material picking robot 15 and the dialing beat of the beat control dial 4 are synchronized by setting a fixed time difference, the continuous synchronous shaping operation of the driving motor rotor core 1 shaping production line is realized under the variable rhythm (or called variable beat) condition.

[0042] The beneficial effects of this embodiment are: the specially designed structure and shape of the beat control dial 4 can cooperate with the infrared detector 7, the drive motor rotor core positioner 9 and the material picking robot 15 to achieve high-reliability variable beat coordinated control of the shaping production line.

[0043] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
