Description

Technical Field

[0001] The present application relates to the field of motor technology, and in particular to a feeding system for assembling a magnetic pole core. Background Art

[0002] The yoke and pole are the key components of the hydro-turbine generator. The yoke and pole of a large hydro-turbine generator are often made of stacked steel plate punchings. The weight of the yoke and pole punchings accounts for about 50-65% of the total weight of the hydro-turbine generator rotor, and is the key component of the hydro-turbine generator. As the core component of the hydro-turbine generator, the pole core provides electromagnetic induction for the hydro-turbine generator. When making the pole core of the hydro-turbine generator, it is necessary to use the positioning tool to axially concentrically position the punching sheet and then press the pole core.

[0003] Punching sheet press-fitting is the process of stacking the pole punching sheet and the pole pressure plate and tightening them with a through-core screw. In the prior art, the pole punching sheets are mainly stacked by manual pressing. When pressing the pole punching sheets, multiple pole punching sheets are manually stacked on the tooling. Positioning holes are opened on the pole punching sheets. During the pressing process, the operator inserts the positioning rod into the positioning hole to assist in stacking the pole punching sheets. The pole punching sheets are pressed by the pressing screw to form the pole core, and finally transferred to the arc welding process by the hoisting mechanism.

[0004] However, the pole punchings of the hydro-turbine generator are large in size. When pressing the pole punchings, the operator needs to use a cart to transport the pole punchings to the tooling for pressing the pole core in multiple times, and then remove the pole punchings one by one and press and stack them on the tooling. The pressing efficiency is low and requires more manpower, so there is room for improvement. Utility Model Content

[0005] In order to achieve the technical effect of automatically conveying magnetic pole punching sheets and improve the efficiency of pressing and installing magnetic pole punching sheets, the present application provides a feeding system for assembling magnetic pole cores.

[0006] The present application provides a feeding system for assembling a magnetic pole core, which adopts the following technical solution:

[0007] A feeding system for assembling a magnetic pole core, comprising a first conveyor belt, a second conveyor belt and a lamination robot, wherein a feeding end of the second conveyor belt is connected to a discharging end of the first conveyor belt, and a conveying speed of the second conveyor belt is greater than that of the first conveyor belt;

[0008] A slide rail is fixedly connected to the ground beside the first conveyor belt and the second conveyor belt, the slide rail is located between the tooling and the first conveyor belt, and the laminating robot is slidably arranged on the slide rail;

[0009] A material unloading mechanism is fixedly installed on the ground at one side of the second conveyor belt away from the stacking robot, a placing table is fixedly installed on the ground at one side of the second conveyor belt away from the first conveyor belt, a visual positioning mechanism is fixedly installed on the ground beside the placing table, and a signal output end of the visual positioning mechanism is signal-connected to a signal input end of the stacking robot.

[0010] By adopting the above technical solution, during the actual pressing process, the magnetic pole punching sheets to be pressed can be placed on the first conveyor belt in advance, and the magnetic pole punching sheets can be conveyed one by one to the second conveyor belt through the first conveyor belt. Since the conveying speed of the second conveyor belt is greater than that of the first conveyor belt, when the magnetic pole punching sheets are conveyed to the second conveyor belt, the distance between the magnetic pole punching sheets can be increased. When the magnetic pole punching sheets are conveyed to the unloading mechanism, the unloading mechanism grabs the magnetic pole punching sheets and transfers them to the placement table, and the image of the punching sheets is collected through the visual positioning mechanism. The stacking robot can accurately grab the pole sheet according to the coordinate data of the pole sheet on the placement table and transfer it to be stacked on the tooling, which can achieve the technical effects of automatic transportation, automatic transfer and automatic positioning of the pole sheet, eliminating the need for operators to manually carry the pole sheet, stack the pole sheet, and press the pole sheet, which can effectively improve the efficiency and accuracy of the pole sheet pressing and save a lot of manpower and time.

[0011] Preferably, a plurality of limit blocks are fixedly connected to the surface of the first conveyor belt.

[0012] By adopting the above technical solution, the limit stopper can facilitate the positioning of the magnetic pole punching sheets and ensure the uniformity of the distance between the magnetic pole punching sheets.

[0013] Preferably, the unloading mechanism comprises a mounting bracket, a guide rail is fixedly connected to the mounting bracket, a sliding seat is slidably connected to the guide rail, a mechanical arm is fixedly connected to the sliding seat, and a vacuum adsorption seat is fixedly connected to the end of the mechanical arm away from the sliding seat, and the vacuum adsorption seat comprises a plurality of vacuum adsorption discs;

[0014] An induction trigger component is fixedly installed on the side of the second conveyor belt, and the induction trigger component is located on the side of the mounting bracket close to the first conveyor belt. The induction trigger component senses the magnetic pole punching conveyed to the second conveyor belt and outputs a punching induction signal;

[0015] The signal output end of the induction trigger component is connected to the signal input end of the unloading mechanism, and the mechanical arm receives the punching sheet induction signal and grabs the magnetic pole punching sheet to the placement table.

[0016] By adopting the above technical solution, when the magnetic pole punching is conveyed from the first conveyor belt to the second conveyor belt, the induction trigger component senses the magnetic pole punching and outputs a punching sensing signal. After receiving the punching sensing signal, the robotic arm moves the vacuum adsorption seat at the end of the robotic arm to adsorb the magnetic pole punching. At the same time, the sliding seat slides to drive the robotic arm that grabs the magnetic pole punching to slide along the axial direction of the guide rail toward the placement table. Subsequently, the vacuum adsorption seat on the robotic arm stops adsorbing the magnetic pole punching, thereby achieving the technical effect of automatic unloading.

[0017] Preferably, mounting rods are fixedly connected to the ground on both sides of the second conveyor belt, and the induction trigger component includes an infrared counter-radiation sensor, and the infrared counter-radiation sensor includes a transmitting end and a receiving end, and the transmitting end and the receiving end are respectively fixedly connected to the two opposite side walls of the mounting rods, and the receiving end senses the magnetic pole punching sheet blocked between the transmitting end and the receiving end and outputs the punching sheet sensing signal.

[0018] By adopting the above technical solution, when the magnetic pole punching sheet is transported between the transmitting end and the receiving end, the receiving end is blocked by the magnetic pole punching sheet and cannot receive infrared rays, and outputs the punching sheet sensing signal, thereby achieving the technical effect of automatically sensing the magnetic pole punching sheet transported to the second conveyor belt and automatically triggering the robotic arm.

[0019] Preferably, a detection bracket is fixedly installed on the ground beside the placement table, and the visual positioning mechanism includes a CCD camera, which is fixedly installed on the detection bracket and is mounted above the placement table;

[0020] A thin film pressure sensor is fixedly connected to the surface of the placement table, and a comparator chip is connected to the signal output end of the thin film pressure sensor. The thin film pressure sensor detects the contact pressure between the magnetic pole punching sheet and the table surface of the placement table and outputs a sensed pressure signal. The comparator chip receives the sensed pressure signal and outputs a collection control signal when the sensed pressure is greater than a set value.

[0021] The signal output terminal of the comparator chip is signal-connected to the signal input terminal of the CCD camera, and the CCD camera receives the acquisition control signal and acquires and outputs the processed film image data;

[0022] The data output end of the CCD camera is connected to an image processor, and the signal output end of the image processor is connected to the signal input end of the stacking robot. The image processor receives the punching image data and outputs a punching coordinate signal. The stacking robot receives the punching coordinate signal and grabs and stacks the magnetic pole punches.

[0023] By adopting the above technical solution, when the unloading mechanism transfers the magnetic pole punching sheet to the placement table, the thin film pressure sensor is pressurized, causing the output induced pressure value to increase. After comparison, the comparator chip determines that the magnetic pole punching sheet is placed on the placement table, and can automatically trigger the CCD camera to collect image data of the magnetic pole punching sheet. After image processing by the image processor, the position of the positioning hole on the magnetic pole punching sheet can be located, which is convenient for the stacking robot to accurately grasp the magnetic pole punching sheet and transfer it to the tooling next to the slide rail.

[0024] In summary, the present application provides a feeding system for assembling a magnetic pole core, which has at least one of the following beneficial technical effects:

[0025] 1. During the actual pressing process, the magnetic pole punching sheets to be pressed can be placed on the first conveyor belt in advance, and the magnetic pole punching sheets can be conveyed one by one to the second conveyor belt through the first conveyor belt. After the magnetic pole punching sheets are conveyed to the second conveyor belt, the unloading mechanism grabs the magnetic pole punching sheets and transfers them to the placement table. The image data of the punching sheets is collected by the visual positioning mechanism, and the coordinates of the positioning holes on the magnetic pole punching sheets are calculated according to the image data of the magnetic pole punching sheets. The stacking robot can accurately grab the magnetic pole punching sheets according to the coordinate data of the magnetic pole punching sheets on the placement table and transfer them to perform stacking on the tooling, which can achieve the technical effects of automatically conveying, automatically transferring and automatically positioning the magnetic pole punching sheets, eliminating the need for operators to manually carry the magnetic pole punching sheets, stack the magnetic pole punching sheets, and press the magnetic pole punching sheets. It can effectively improve the efficiency and accuracy of the pressing of the magnetic pole punching sheets and save a lot of manpower and time.

[0026] 2. By fixing the vacuum adsorption seat at the bottom of the robot arm, the technical effect of automatically grabbing and releasing the pole punching can be achieved. The pole punching on the second conveyor belt can be transferred to the placement table for visual positioning, which is convenient for the stacking robot to accurately grab and stack the pole punching.

[0034] A material unloading mechanism 5 is fixedly installed on the ground on the side of the second conveyor belt 2 away from the stacking robot 3, a placing table 6 is fixedly installed on the ground on the side of the second conveyor belt 2 away from the first conveyor belt 1, and a visual positioning mechanism 7 is fixedly installed on the ground beside the placing table 6. The signal output end of the visual positioning mechanism 7 is connected to the signal input end of the stacking robot 3.

[0035] During the actual pressing process, the pole punchings to be pressed can be placed on the first conveyor belt 1 in advance, and the pole punchings can be conveyed one by one to the second conveyor belt 2 through the first conveyor belt 1. When the pole punchings are conveyed to the unloading mechanism 5, the unloading mechanism 5 grabs the pole punchings and transfers them to the placement table 6. The image data of the punchings is collected by the visual positioning mechanism 7, and the coordinates of the positioning holes on the pole punchings are calculated according to the image data of the pole punchings. The stacking robot 3 can accurately grab the pole punchings according to the coordinate data of the pole punchings on the placement table 6 and transfer them to be stacked on the tooling 4, which can achieve the technical effects of automatically conveying, transferring and positioning pole punchings, eliminating the need for operators to manually carry, stack and press the pole punchings, etc., which can effectively improve the efficiency and accuracy of the pressing of the pole punchings and save a lot of manpower and time.

[0036] Wherein, the first conveyor belt 1 and the second conveyor belt 2 are both chain conveyor belts, and the conveying speed of the second conveyor belt 2 is greater than that of the first conveyor belt 1 .

[0037] Since the conveying speed of the second conveyor belt 2 is greater than that of the first conveyor belt 1, when the magnetic pole punchings are conveyed onto the second conveyor belt 2, the distance between the magnetic pole punchings can be increased, thereby preventing collision between the magnetic pole punchings.

[0038] It should be noted that in the present application, the robot takes and places the magnetic pole core through a magnetic suction seat. This is a prior art and is not limited here.

[0041] An induction trigger assembly 8 is fixedly installed on the side of the second conveyor belt 2. The induction trigger assembly 8 is located on the side of the mounting bracket 51 close to the first conveyor belt 1. The induction trigger assembly 8 senses the magnetic pole punching conveyed to the second conveyor belt 2 and outputs a punching induction signal.

[0042] The signal output end of the induction trigger component 8 is connected to the signal input end of the unloading mechanism 5 , and the robot arm 54 receives the punching sheet induction signal and grabs the magnetic pole punching sheet to the placement table 6 .

[0043] During the process of conveying the magnetic pole punching via the first conveyor belt 1 to the second conveyor belt 2, the induction trigger component 8 senses the magnetic pole punching and outputs a punching sensing signal. After receiving the punching sensing signal, the robotic arm 54 moves the vacuum adsorption seat 55 at the end of the robotic arm 54 to adsorb the magnetic pole punching. At the same time, the sliding seat 53 slides to drive the robotic arm 54 that grabs the magnetic pole punching to slide along the axial direction of the guide rail 52 toward the placement table 6. Then, the vacuum adsorption seat 55 on the robotic arm 54 stops adsorbing the magnetic pole punching, thereby achieving the technical effect of automatic unloading.

[0044] Reference Figure 1 , mounting rods 81 are fixedly connected to the ground on both sides of the second conveyor belt 2, the induction trigger component 8 includes an infrared counter-radiation sensor, the infrared counter-radiation sensor includes a transmitting end 82 and a receiving end 83, the transmitting end 82 and the receiving end 83 are respectively fixedly connected to the opposite side walls of the two mounting rods 81, and the receiving end 83 senses the magnetic pole punching sheet blocked between the transmitting end 82 and the receiving end 83 and outputs the punching sheet sensing signal.

[0045] When the magnetic pole punching sheet is transported between the transmitting end 82 and the receiving end 83, the receiving end 83 is blocked by the magnetic pole punching sheet and cannot receive infrared rays, and outputs a punching sheet sensing signal, thereby achieving the technical effect of automatically sensing the magnetic pole punching sheet transported to the second conveyor belt 2 and automatically triggering the robot arm 54.

[0047] A thin film pressure sensor is fixedly connected to the surface of the placement table 6, and the signal output end of the thin film pressure sensor is connected to a comparator chip. The thin film pressure sensor detects the contact pressure between the magnetic pole punching sheet and the surface of the placement table 6 and outputs a sensed pressure signal. The comparator chip receives the sensed pressure signal and outputs a collection control signal when the sensed pressure is greater than a set value.

[0048] The signal output terminal of the comparator chip is connected to the signal input terminal of the CCD camera. The CCD camera receives the acquisition control signal and acquires and outputs the processed film image data.

[0049] The data output end of the CCD camera is connected to the image processor, and the signal output end of the image processor is connected to the signal input end of the stacking robot 3. The image processor receives the punching image data and outputs the punching coordinate signal. The stacking robot 3 receives the punching coordinate signal and grabs and stacks the magnetic pole punches.

[0050] When the unloading mechanism 5 transfers the pole punching sheet to the placement table 6, the thin film pressure sensor is pressurized, causing the output induced pressure value to increase. After comparison, the comparator chip determines that the pole punching sheet is placed on the placement table 6, and can automatically trigger the CCD camera to collect image data of the pole punching sheet. After image processing by the image processor, the position of the positioning hole on the pole punching sheet can be located, which is convenient for the stacking robot 3 to accurately grasp the pole punching sheet and transfer it to the tooling 4 next to the slide rail 31.

The image data of the punchings is collected by the visual positioning mechanism 7, and the coordinates of the positioning holes on the pole punchings are calculated according to the image data of the pole punchings. The stacking robot 3 can accurately grab the pole punchings according to the coordinate data of the pole punchings on the placement table 6 and transfer them to perform stacking on the tooling 4, which can achieve the technical effects of automatically conveying, automatically transferring, and automatically positioning pole punchings, eliminating the need for operators to manually carry, stack, and press the pole punchings, etc., which can effectively improve the efficiency and accuracy of the press-fitting of the pole punchings and save a lot of manpower and time.
