Description

Technical Field

[0001] The invention relates to the technical field of iron core manufacturing, and mainly to an iron core detection commutation device and method. Background Art

[0002] The contactor core is mainly composed of two parts: the static core and the moving core. The static core is generally fixed on the base of the contactor and is the stationary part. The moving core can move under the action of electromagnetic force. The core is usually made of materials with good electromagnetic properties, such as electrical pure iron or silicon steel sheets, and is formed by stacking. However, the opening direction of the existing core is fixed, and the core is transported in a disordered and chaotic manner during the processing. The core needs to be reversed and sorted so that the opening direction of the core is consistent, which is convenient for the subsequent installation of the copper coil on the opening of the core.

[0003] For example, in a Chinese patent application with patent number 202322387050.7, an AC contactor core is specifically disclosed, including a core body, a short-circuit ring and a fixing mechanism, wherein the core body is formed by stacking a plurality of core sheets.

[0004] However, due to the disordered and chaotic placement of the iron core, when the iron core is reversed, the opening direction of the iron core needs to be identified first. The current mainstream identification method is to identify the opening direction of the iron core through a visual recognition device. Although the visual recognition device is sensitive, it has high environmental requirements and high manufacturing costs. Summary of the invention

[0005] In response to the above problems, the present invention provides an iron core detection commutation device and method, which replaces the visual recognition device through the cooperation of two groups of laser sensors, reduces the manufacturing cost, and can still accurately identify the opening direction of the iron core, and greatly reduces maintenance costs.

[0006] The technical solution adopted by the core detection commutation device and method provided in the present application is as follows: An iron core detection and commutation device, the iron core detection and commutation device is used to detect and commutate an iron core arranged with an M-shaped opening in the length direction, and the iron core detection and commutation device comprises: Input line, output line and detection switching mechanism; The input line and the output line both transport the iron core horizontally along the length direction of the iron core, the output end of the input line is connected with the input end of the output line through the detection reversing mechanism, the input lines input the iron cores one by one, and the output lines output the iron cores one by one with the M-shaped opening facing the same direction; The detection and reversing mechanism includes a detection component, a side push component and a reversing component. The detection component includes a sensor and a laser sensor. The sensor is arranged opposite to the output end. The sensor senses the iron core to be detected and reversed that is transported by the input line. Two groups of laser sensors are arranged. The laser sensors of the two groups are located at the same horizontal height above the sensor. The laser sensor detects and determines the M-shaped opening direction of the iron core. The pushing direction of the side push component is arranged perpendicular to the conveying direction of the input line. The side push component is arranged horizontally toward the reversing component, and the side push component pushes the detected iron core to the reversing component. The reversing component is arranged opposite to the input end. The reversing component includes a rotating cylinder and a pushing cylinder. The rotating cylinder is arranged to rotate, and a reversing groove for accommodating the iron core is opened at the central axis of the rotating cylinder. The pushing cylinder is arranged opposite to the central axis of the rotating cylinder. The pushing cylinder pushes the iron core that has completed reversing in the reversing groove to the output line.

[0007] As an improvement, the input line and the output line both include a conveyor belt, a guardrail and a block. The conveyor belt is arranged in a rotating manner, and the guardrail and the block are arranged on both sides of the conveying direction of the conveyor belt. The guardrail and the edge of the block cooperate to form a conveying channel.

[0008] As an improvement, two groups of laser sensors are arranged on both sides of the conveying direction of the input line, and the distances from the two groups of laser sensors to the center line of the conveying direction of the input line are equal; The two groups of laser sensors are arranged on both sides of the pushing direction of the side thrust assembly, and the distances from the two groups of laser sensors to the center line of the pushing direction of the side thrust assembly are equal.

[0009] As an improvement, the spacing distance of the M-shaped openings of the iron core is D, and the width of a single opening of the iron core is S, then the spacing L between the two groups of laser sensors in the transmission direction of the input line satisfies the relationship: D<L<D+2S.

[0010] As an improvement, the height of the iron core is H, and the depth of the opening of the iron core in its height direction is Q, then the spacing T between the two groups of laser sensors in the pushing direction of the side thrust assembly satisfies the relationship: Q<T<H.

[0011] As an improvement, the two groups of laser sensors include a first laser sensor disposed near the output end and the side thrust assembly and a second laser sensor disposed near the sensor and the reversing assembly.

[0012] As an improvement, when the M-shaped opening of the iron core to be detected for reversal faces the side thrust assembly, the first laser sensor measures the laser reflection time difference as t1, and the second laser sensor measures the laser reflection time difference as t2, and the rotating cylinder receives a signal from a processor connected to the laser sensor and does not rotate.

[0013] As an improvement, when the M-shaped opening of the iron core to be detected for commutation faces the commutation assembly, the first laser sensor measures the laser reflection time difference as t2, and the second laser sensor measures the laser reflection time difference as t1, and the rotating cylinder receives a signal from a processor connected to the laser sensor and rotates 180° clockwise or counterclockwise.

[0014] As an improvement, when the M-shaped opening of the iron core to be detected for commutation faces the laser sensor, the first laser sensor and the second laser sensor both measure the laser reflection time difference as t3, and the rotating cylinder receives a signal from a processor connected to the laser sensor and rotates 90° clockwise or 270° counterclockwise.

[0015] As an improvement, when the M-shaped opening of the iron core to be detected for commutation faces away from the laser sensor, the first laser sensor and the second laser sensor both measure the laser reflection time difference as t4, and the rotating cylinder receives a signal from a processor connected to the laser sensor and rotates 90° counterclockwise or 270° clockwise.

[0016] In addition, the present invention provides a method for detecting a commutation device based on any one of the above-mentioned cores, comprising the following steps: Step s1, input, the disorderly arranged iron cores are transported one by one through the input line to the detection switching mechanism located at the output end of the input line; Step s2, detection, after the detection component in the detection switching mechanism detects the iron core through a sensor, the laser sensor in the detection component detects the iron core to determine the opening direction of the iron core; Step s3, pushing, after the laser sensor in step s2 determines the direction of the M-shaped opening of the iron core according to the laser reflection time difference t, the side push component in the detection reversing mechanism pushes toward the reversing component in the detection reversing mechanism; Step s4, reversing, after receiving the iron core pushed by the side thrust assembly, the rotating cylinder in the reversing assembly rotates a corresponding angle according to the direction of the M-shaped opening of the iron core detected in step s2, so that the M-shaped opening of the iron core faces the side thrust assembly; Step s5, output, after the iron core in step s4 completes reversing, it is pushed toward the input end of the output line by the pushing cylinder in the reversing assembly, so that the iron core enters the output line and is output.

[0017] The beneficial effects of the present invention are: (1) The present invention replaces the visual recognition device by using two sets of laser sensors to detect the iron core in different opening orientations, and uses the laser reflection time difference obtained by the detection as the basis for judging the opening orientation of the iron core, thereby determining the opening orientation of the iron core. Compared with the visual recognition detection technology, the present invention can be applied to more severe working conditions, and has lower production costs, lower maintenance costs, and is more reliable. (2) The present invention realizes the rotation reversal of the iron core by utilizing the rotation switching of the rotating cylinder, replacing the existing robot arm grasping the iron core for reversing. The structure is more stable, the response is more sensitive, and the processing efficiency is higher.

[0024] Embodiment 1: like Figures 1 to 14 As shown, an iron core detection and commutation device is used to detect and commutate an iron core 10 with an M-shaped opening in the length direction, and the iron core detection and commutation device includes: Input line 1, output line 2 and detection reversing mechanism 3; The input line 1 and the output line 2 both transport the iron core 10 horizontally along the length direction of the iron core 10, the output end 14 of the input line 1 and the input end 21 of the output line 2 are connected through the detection reversing mechanism 3, the input line 1 inputs the iron core 10 one by one, and the output line 2 outputs the iron core 10 one by one with the M-shaped opening facing the same direction; The detection and reversing mechanism 3 includes a detection component 31, a side thrust component 32 and a reversing component 33. The detection component 31 includes a sensor 311 and a laser sensor 312. The sensor 311 is arranged opposite to the output end 14. The sensor 311 senses the iron core 10 to be detected and reversed, which is transported by the input line 1. Two groups of laser sensors 312 are arranged. Both groups of laser sensors 312 are located at the same horizontal height above the sensor 311. The laser sensor 312 detects and determines the M-shaped opening direction of the iron core 10. The pushing direction of the side thrust component 32 is perpendicular to the transport direction of the input line 1. The side push assembly 32 is arranged vertically, and is arranged horizontally toward the reversing assembly 33, and the side push assembly 32 pushes the detected iron core 10 to the reversing assembly 33, and the reversing assembly 33 is arranged opposite to the input end 21. The reversing assembly 33 includes a rotating cylinder 331 and a pushing cylinder 332. The rotating cylinder 331 is arranged to rotate, and a reversing groove 333 for accommodating the iron core 10 is opened at the central axis of the rotating cylinder 331. The pushing cylinder 332 is arranged opposite to the central axis of the rotating cylinder 331, and the pushing cylinder 332 pushes the iron core 10 that has completed reversing in the reversing groove 333 to the output line 2.

[0025] Among them, the input line 1 and the output line 2 both include a conveyor belt 11, a guardrail 12 and a stopper 13. The conveyor belt 11 is arranged in a rotating manner. The guardrail 12 and the stopper 13 are arranged on both sides of the conveying direction of the conveyor belt 11. The edges of the guardrail 12 and the stopper 13 cooperate to form a conveying channel 100.

[0026] It should be noted that when the iron core 10 is conveyed by the input line 1, since the iron core 10 itself is in the shape of a rectangular parallelepiped, it is difficult to pass the sorting of the vibrating screening mechanism, so that the opening directions of the iron core 10 are all in the same direction, and the screening and sorting of the vibrating screening mechanism can only achieve the unification of the length direction of the iron core. Therefore, when the iron core 10 is conveyed by the input line 1, the length direction of the iron core 10 is unified, and the length direction of the iron core 10 is consistent with the conveying direction of the conveying line 1. The iron core 10 in the present invention is arranged in an M-shaped opening, specifically, two openings 101 are opened in the length direction of the iron core 10, and the two openings 101 are symmetrically arranged along the midline of the length direction of the iron core 10.

[0027] The present application uses two groups of laser sensors 312 to detect the opening direction of the iron core 10, replacing the original visual detection. First, the two groups of laser sensors 312 in the present application are arranged on both sides of the conveying direction of the input line 1, and the distances from the two groups of laser sensors 312 to the center line of the conveying direction of the input line 1 are equal; at the same time, the two groups of laser sensors 312 are arranged on both sides of the pushing direction of the side thrust assembly 32, and the distances from the two groups of laser sensors 312 to the center line of the pushing direction of the side thrust assembly 32 are equal. In summary, the two groups of laser sensors 312 are both located above the iron core 10 to be rotated and reversed, and the two groups of laser sensors 312 are both arranged on the diagonal lines of the iron core 10, and the two groups of laser sensors are both arranged corresponding to the opening 101 on the iron core 10.

[0028] The spacing distance of the M-shaped openings of the iron core 10 is D (i.e., the width of the iron core part between the two openings 101 is D), and the width of a single opening of the iron core 10 is S (i.e., the width of the opening 101 is S), then the spacing L between the two groups of laser sensors 312 in the conveying direction of the input line 1 (i.e., the length direction of the iron core 10) satisfies the relationship: D<L<D+2S (i.e., the setting positions of the two groups of laser sensors 312 are just located within the opening range of the corresponding opening 101).

[0029] At the same time, the height of the iron core 10 is H, and the depth of the opening of the iron core 10 in its height direction is Q, then the spacing T between the two groups of laser sensors 312 in the pushing direction of the side thrust assembly 32 satisfies the relationship: Q<T<H. It is defined here that when the height direction of the iron core 10 is in a horizontal state, one group of the two groups of laser sensors 312 is located within the range of the opening 101, and the other group of laser sensors 312 is located outside the range of the opening 101, that is, within the range of the main body of the iron core 10 (that is, the metal part of the iron core 10).

[0030] In the present invention, the two groups of laser sensors 312 include a first laser sensor 312A disposed near the output end 14 and the side thrust assembly 32 and a second laser sensor 312B disposed near the sensor 311 and the reversing assembly 33 .

[0031] The principle of the laser sensor 312 detecting the iron core 10 and determining the opening direction of the iron core 10 is to use the laser sensor 312 to emit a laser to the iron core 10. After the laser is irradiated on the iron core 10, part of the laser will be reflected back. The receiving device inside the sensor can detect the reflected light. By calculating the time difference between the laser emission and the reflection back, combined with the speed of light, the distance between the object and the sensor can be determined. At the same time, the laser sensor can also perceive other characteristics such as the surface characteristics and shape of the object by analyzing the intensity, frequency and other information of the reflected light.

[0032] Specifically, the basic working principle of the two sets of laser sensors 312 of the present application to perform M-shaped opening detection on the iron core 10 is: like Figure 4 As shown, in case 1, when the M-shaped opening of the iron core 10 to be detected for reversal faces the side thrust assembly 32 (at this time, the height direction of the iron core 10 is in a horizontal state), the first laser sensor 312A (at this time, the laser emitted by the first laser sensor 312A just irradiates the opening 101 of the iron core 10) measures the laser reflection time difference as t1, and the second laser sensor 312B (at this time, the laser emitted by the second laser sensor 312B just irradiates the body of the iron core 10) measures the laser reflection time difference as t2. The time difference is t2. Due to the height difference, t1>t2. After comparing the laser reflection time difference through the processor, it can be concluded that the opening direction of the iron core 10 is just opposite to the side thrust assembly 32, and the opening direction of the iron core 10 determined by the present invention is this direction. Therefore, the processor sends an instruction to the side thrust assembly 32 to push the iron core 10 into the rotating cylinder 331, and the rotating cylinder 331 receives the signal sent by the processor and does not rotate, maintaining the opening direction of the iron core 10, and then it is pushed out by the pushing cylinder 332.

[0033] like Figure 5As shown, in case 2, when the M-shaped opening of the iron core 10 to be detected for reversing faces the reversing assembly 33, the first laser sensor 312A (the laser emitted by the first laser sensor 312A at this time just irradiates the body of the iron core 10) measures the laser reflection time difference as t2, and the second laser sensor 312B measures the laser reflection time difference as t1 (the laser emitted by the second laser sensor 312B at this time just irradiates the opening 101 of the iron core 10). The laser reflection time difference obtained at this time is just opposite to that in case 1. After comparing the laser reflection time difference through the processor, it can be concluded that the opening direction of the iron core 10 at this time is just opposite to that in case 1. Therefore, the processor sends an instruction to the side thrust assembly 32 to push the iron core 10 into the rotating cylinder 331, and the rotating cylinder 331 receives the signal sent by the processor and rotates 180° clockwise or counterclockwise to make the opening of the iron core 10 face the conversion position toward the side thrust assembly 32, and then is pushed out by the pushing cylinder 332.

[0034] like Figure 6 As shown, in case 3, when the M-shaped opening of the iron core 10 to be detected for reversal faces the laser sensor 312 (at this time, the height direction of the iron core is in a vertical state, the M-shaped opening faces upward, and the lasers emitted by the first laser sensor 312A and the second laser sensor 312B are respectively irradiated into the corresponding opening 101), the first laser sensor 312A and the second laser sensor 312B both measure the laser reflection time difference as t3. After the processor obtains the laser reflection time difference data, it sends an instruction to the side thrust assembly 32 to push the iron core 10 into the rotating cylinder 331. The rotating cylinder 331 receives the signal sent by the processor and rotates 90° clockwise or 270° counterclockwise, so that the opening of the iron core 10 faces the conversion position toward the side thrust assembly 32, and then is pushed out by the pushing cylinder 332.

[0035] like Figure 7 As shown, in case 4, when the M-shaped opening of the iron core 10 to be detected for reversal faces away from the laser sensor 312 (at this time, the height direction of the iron core is in a vertical state, the M-shaped opening faces downward, and the lasers emitted by the first laser sensor 312A and the second laser sensor 312B are respectively irradiated on the body of the iron core 10), the first laser sensor 312A and the second laser sensor 312B both measure the laser reflection time difference as t4 (t4 is significantly shorter than t3). After the processor obtains the laser reflection time difference data, it sends an instruction to the side thrust assembly 32 to push the iron core 10 into the rotating cylinder 331. The rotating cylinder 331 receives the signal sent by the processor and rotates 90° counterclockwise or 270° clockwise, so that the opening of the iron core 10 faces the conversion position and faces the side thrust assembly 32, and is then pushed out by the pushing cylinder 332.

[0036] In addition, in the present invention, the setting positions of the two groups of laser sensors 312 are not limited to the above-mentioned positions. The first laser sensor 312A can also be set close to the output end 14 and the reversing component 33, while the second laser sensor 312B is set close to the sensor 311 and the side thrust component 32. At this time, the setting method of the laser sensor 312 is the same as the above-mentioned setting method, and the laser reflection time difference measured in Case 1 and Case 2 is exactly opposite.

[0037] It is also necessary to explain in detail that the rotating cylinder 331 in the present application is actively rotated by the servo motor 334 in cooperation with the gear set 335. The servo motor 334 is controlled by the processor through electrical signals and can accurately drive the rotating cylinder 331 to rotate a corresponding angle.

[0038] Furthermore, it should be noted that a support block 336 is also provided below the rotating cylinder 331. The upper end surface of the support block 336 is initially tangent to the outer wall of the rotating cylinder 331. At the same time, the support block 336 can be lifted by a lifting cylinder 337 vertically provided below. For example, when the rotating cylinder 331 rotates until the reversing groove 333 faces the support block 336, the lifting cylinder 337 lifts the support block 336 to lift the iron core 10 to the center position of the rotating cylinder 331, making it easier for the pushing cylinder 332 to push the iron core to the output line 2.

[0039] It should also be noted that a guide channel 338 is provided at the connection position between the rotating cylinder 331 and the output line 2 for guiding the iron core 10 pushed by the pushing cylinder 332. The guide channel 338 is arranged in a bell-mouth shape, so that the iron core 10 pushed by the pushing cylinder 332 can be guided through the guide channel 338 and aligned with the output line 2 for output.

[0040] Embodiment 2: like Fig.15 As shown, referring to the first embodiment, a method for detecting a commutation device of an iron core according to the second embodiment of the present invention based on the first embodiment is described, comprising the following steps: Step s1, input, the randomly arranged iron cores 10 are transported one by one through the input line 1 to the detection switching mechanism 3 located at the output end 14 of the input line 1; Step s2, detection, after the detection component 31 in the detection reversing mechanism 3 detects the iron core 10 through the sensor 311, the laser sensor 312 in the detection component 31 detects the iron core 10 to determine the opening direction of the iron core 10; Step s3, pushing, after the laser sensor 312 in step s2 determines the direction of the M-shaped opening of the iron core 10 according to the laser reflection time difference t, the side push component 32 in the detection reversing mechanism 3 pushes toward the reversing component 33 in the detection reversing mechanism 3; Step s4, reversing. After receiving the iron core 10 pushed by the side thrust assembly 32, the rotating cylinder 331 in the reversing assembly 33 rotates a corresponding angle according to the direction of the M-shaped opening of the iron core 10 detected in step s2, so that the M-shaped opening of the iron core 10 faces the side thrust assembly 32. Step s5, output. After the iron core 10 in step s4 completes the reversal, it is pushed toward the input end 21 of the output line 2 by the pushing cylinder 332 in the reversing assembly 33, so that the iron core 10 enters the output line 2 and is output.

[0041] It should be noted that the present invention uses the laser sensor 312 instead of visual detection, and utilizes the difference in laser reflection time difference t between two groups of laser sensors 312 to determine the opening direction of the core 10 .

[0042] It is further explained that the sensor 311 is connected to the processor through an electrical signal. The sensor 311 is an inductive sensor. The sensor 311 is composed of high-frequency oscillation, detection, amplification, triggering and output circuits. The oscillator generates an alternating electromagnetic field on the sensor detection surface. When the iron core 10 approaches, eddy currents are generated in the iron core 10 to absorb the oscillator energy, causing the oscillation to weaken and stop. The oscillation and stop state of the oscillator are converted into electrical signals, which are converted into binary switching signals after shaping and amplification, and are output to the processor after power amplification. After receiving the signal, the processor controls the side thrust assembly 32 to push the iron core 10.

[0043] It is further explained that the working principle of the laser sensor 312 for determining the opening direction of the core 10 is specifically defined in the first embodiment.

[0044] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
