Description

Technical Field

[0001] The present invention relates to the field of motor assembly equipment technology, in particular to a magnetic steel assembly glue coating machine and an operating method thereof. Background Art

[0002] In the process of assembling the magnets of the motor core, the traditional method is to first fix the magnets on the jig, and then insert the magnets into the core through the profiling jig. This operation method is not only cumbersome but also inefficient because it involves multiple independent operation steps and requires precise alignment and insertion, which is particularly time-consuming and error-prone in large-scale production. In addition, in order to ensure that the size of the core meets the requirements, the outer diameter and shaft height need to be accurately detected before the magnets are inserted. The current practice is to set up an outer diameter detection mechanism and a shaft height detection mechanism separately, which are set independently and spaced from each other, and the intermediate material transfer requires a separate handling mechanism; this means that the core needs to be transported back and forth between two different inspection stations, which not only increases the complexity of the operation, but also reduces the efficiency of the inspection. This step-by-step inspection method leads to bottlenecks in the production process, increasing waiting time and production costs.

[0003] Therefore, the prior art urgently needs a more simplified and efficient equipment and operating method to reduce the operating steps, improve production efficiency, reduce costs, and reduce the time and production costs caused by multiple handling and inspections for iron core inspection, magnetic steel assembly and glue coating operations.

[0034] The present invention Figures 1 to 10 As shown, a magnetic steel assembly glue coating machine and an operating method thereof, wherein:

[0035] The magnetic steel assembly gluing machine includes a frame 10, a detection mechanism 20 installed on the frame 10, a magnetic steel inserting mechanism 30 for inserting the magnetic steel into the iron core 60, a gluing mechanism 40 for gluing the iron core 60 after the magnetic steel is inserted, and a transporting device 50 for transporting the iron core 60 between the detection mechanism 20, the magnetic steel inserting mechanism 30 and the gluing mechanism 40.

[0036] The detection mechanism 20 includes an outer diameter detection component 21, an axis height detection component 22 and a temperature detection sensor 23, and the outer diameter detection component 21 and the axis height detection component 22 are integrated on the same detection bracket 25; the temperature detection sensor 23 is located beside the outer diameter detection component 21 and the axis height detection component 22; the magnetic steel insertion mechanism 30 includes a magnetic steel feeding component 31 and an inserted magnetic steel component 32, and the magnetic steel feeding component 31 and the inserted magnetic steel component 32 are connected; the glue coating mechanism 40 includes a weighing component 41, a glue connecting component 42 and a glue coating component 43, and the glue coating component 43 is located above the weighing component 41 and the glue connecting component 42; the conveying device 50 is located between the detection mechanism 20, the magnetic steel insertion mechanism 30 and the glue coating mechanism 40.

[0037] The detection mechanism 20 also includes a first transfer device 24, which includes a first transfer bracket 241, a first drive motor 242, a first screw rod 243 and a first sliding seat 244. The first transfer bracket 241 is located beside the detection bracket 25, and the first drive motor 242 is installed at the end of the first transfer bracket 241; the first screw rod 243 is rotatably installed on the first transfer bracket 241 and is connected to the shaft end of the first drive motor 242; the first sliding seat 244 is slidably installed on the first transfer bracket 241. On a transfer bracket 241, and rotatably cooperated with the first screw rod 243; a first material receiving platform 245 for placing the iron core 60 and a first rotary drive motor 246 for driving the first material receiving platform 245 to rotate are rotatably arranged on the first sliding seat 244, and the first material receiving platform 245 is connected to the output end of the first rotary drive motor 246; and an extension hole 2451 is arranged on the first material receiving platform 245 corresponding to the lower end of the iron core 60, so that when the iron core 60 is detected, its lower end enters the shaft height detection component 22 through the extension hole 2451.

[0038] The outer diameter detection component 21 includes an outer diameter detection sleeve 211, an elastic detection probe 212 vertically extending into the detection sleeve, a distance sensor 213 and an outer diameter detection drive cylinder 214. The outer diameter detection drive cylinder 214 is installed on the upper end of the detection bracket 25, the outer diameter detection sleeve 211 is installed on the output end of the outer diameter detection drive cylinder 214, and the elastic detection probe 212 is elastically floatingly installed vertically at the center of the outer diameter detection sleeve 211; the first material receiving platform 245 is movably located below the outer diameter detection sleeve 211; the distance sensor 213 is installed on the detection bracket 25 and is located above the elastic detection probe 212.

[0039] Before the outer diameter detection and shaft height detection of the iron core 60, the temperature detection sensor 23 will perform temperature detection on the iron core 60 (the previous process is the heating process of the iron core 60). Only after the iron core 60 is cooled to the standard temperature can the subsequent detection operation be performed to avoid inaccurate detection due to temperature influence.

[0040] When the outer diameter of the iron core 60 is detected, the first material receiving platform 245 transfers the iron core 60 to the bottom of the outer diameter detection sleeve 211, and the outer diameter detection driving cylinder 214 drives the outer diameter detection sleeve 211 to move downward, and the iron core 60 enters the outer diameter detection sleeve 211; when the outer diameter of the iron core 60 exceeds the standard design size, the iron core 60 cannot enter the inner top of the outer diameter detection sleeve 211, and the elastic detection probe 212 will not be resisted and rise to the standard position, and the distance sensor 21 3. If the elastic detection probe 212 cannot be detected to float upward, the outer diameter of the core 60 is determined to be unqualified, and the first receiving platform 245 transfers the unqualified core 60 out; if the outer diameter of the core 60 does not exceed the standard design size, the core 60 will enter the outer diameter detection sleeve 211 as the outer diameter detection sleeve 211 moves downward, thereby triggering the elastic detection probe 212 to float upward, and the distance sensor 213 detects the elastic detection probe 212 floating upward, and determines that the outer diameter of the core 60 is qualified. At the same time, when the outer diameter detection sleeve 211 moves upward and separates from the core 60, the elastic force of the elastic detection probe 212 abutting against the core 60 can prevent the core 60 from moving upward with the outer diameter detection sleeve 211, thereby achieving smooth material removal.

[0041] The shaft height detection component 22 includes a shaft height detection seat 221, a U-shaped end face abutment block 222 for abutting the lower end face of the iron core 60, a GT sensor 223 and a shaft height detection drive cylinder 224, the shaft height detection drive cylinder 224 is vertically installed at the lower end of the detection bracket 25, and the shaft height detection seat 221 is installed on the output end of the shaft height detection drive cylinder 224; the U-shaped end face abutment block 222 is installed on the shaft height detection seat 221, and a through hole 2211 is opened on the shaft height detection seat 221 corresponding to the rotating shaft of the iron core 60; the GT sensor 223 is installed at the lower end of the shaft height detection seat 221, and the detection axis of the GT sensor 223 can be elastically telescopically extended upward into the U-shaped end face abutment block 222.

[0042] While the outer diameter of the core 60 is being detected, the shaft height detection assembly 22 detects the shaft height of the core 60. The shaft height detection drive cylinder 224 drives the shaft height detection seat 221 to move upward, and the U-shaped end face abutment block 222 gradually abuts against the lower end face of the core 60 as the shaft height detection drive cylinder 224 is driven. In this process, the lower end of the upper shaft of the core 60 extends downward from the through hole 2211 to abut against the detection shaft end of the GT sensor 223, forming an abutment against the detection shaft of the GT sensor 223 (the detection shaft is in an elastic and retractable form). Pressure; when the U-shaped end face abutment block 222 is completely abutted against the lower end face of the iron core 60, the detection shaft is also compressed downward by a certain distance and stops, and the distance between the top end of the detection shaft and the top end of the U-shaped end face abutment block 222 changes (before detection, the distance between the top end of the detection shaft and the top end of the U-shaped end face abutment block 222 is a standard value). The shaft height of the iron core 60 (the distance between the lower end of the shaft and the lower end face of the iron core 60) can be measured by the downward movement stroke of the detection shaft (the change in the distance between the top end of the detection shaft and the top end of the U-shaped end face abutment block 222).

[0043] By installing the outer diameter detection component 21 and the shaft height detection component 22 on the same detection bracket 25, the outer diameter and shaft height of the iron core 60 can be detected simultaneously without the need to transfer materials in the middle, thus reducing the number of processes and corresponding mechanisms, effectively improving the detection efficiency of the iron core 60 and reducing production costs.

The material dividing support seat 3112 is installed above the material dividing bracket 3111, and the material dividing cylinder 3113 is installed on the material dividing support seat 3112. The material dividing slider 3114 can be slidably installed on the material dividing support seat 3112 and is connected to the output end of the material dividing cylinder 3113; The material distribution support seat 3112 is provided with a material insertion groove 31121; the material distribution slide block 3114 is provided with a material distribution groove 31141. When the magnetic steel enters the material distribution groove 31141 (the material distribution groove 31141 is connected to the discharge port of the direct vibration feeder, the direct vibration feeder is connected to the vibration plate containing the magnetic steel, and the magnetic steel enters the material distribution groove 31141 from the discharge port), the material distribution cylinder 3113 drives the material distribution slide block 3114 to move forward so that the material distribution groove 31141 and the material insertion groove 31121 form a vertical corresponding state. A material sensor 3115 is provided at the rear end of the material distribution support seat 3112. When the material sensor 3115 detects the material coming from the discharge port, the material distribution cylinder 3113 drives the material distribution slide block 3114 to move forward to receive the material.

[0045] The magnetic steel inserting assembly 32 includes a magnetic steel inserting bracket 321, a magnetic steel inserting driving cylinder 322 and an inserting block 323. The magnetic steel inserting driving cylinder 322 is installed on the magnetic steel inserting bracket 321, and the inserting block 323 is installed on the output end of the magnetic steel inserting driving cylinder 322 and vertically corresponds to the inserting slot 31121. The magnetic steel inserting driving cylinder 322 drives the inserting block 323 to move downward to insert the magnetic steel in the material distribution slot 31141 downward into the inserting slot 31121, and enter the magnetic steel slot on the end surface of the iron core 60; this mechanism abandons the form of the traditional magnetic steel inserting that requires an iron core profiling mold, saves the operation of transferring the magnetic steel and attaching it to the profiling mold, and directly inserts the magnetic steel into the iron core 60, simplifies the equipment structure and production process, speeds up the assembly efficiency of the magnetic steel, and reduces the production cost.

A positioning pin 3351 for positioning the iron core 60 is provided on the second material receiving platform 335 corresponding to the iron core 60. A positioning hole is provided on the end surface of the iron core 60 correspondingly. The positioning pin 3351 is inserted into the positioning hole to position the iron core 60. The second material receiving platform 335 is movably located below the insertion slot 31121. In addition, a chip suction hole connected to the vacuum generator is provided at the center of the second material receiving platform 335. The chips generated during the magnetic steel insertion process on the iron core 60 will be cleaned through the chip suction hole to improve the cleanliness of the iron core 60.

[0047] The magnetic steel insertion mechanism 30 also includes a positioning detection device 34. The positioning detection device 34 (laser displacement sensor) detects the positioning holes of the iron core 60 on the second material receiving platform 335 (detects the position of one of the positioning holes). The second rotary drive motor 336 cooperates with the positioning detection device 34 to rotate the iron core 60 until one of its positioning holes is detected by the positioning detection device 34. The second rotary drive motor 336 stops driving to position the iron core 60, which is convenient for subsequent magnetic steel insertion operations.

[0048] After a magnetic steel slot on the iron core 60 is inserted with a magnetic steel slot, the second rotary drive motor 336 drives the second receiving platform 335 to rotate a certain angle, so that another magnetic steel slot is aligned with the inserting slot 31121, and the next magnetic steel is inserted, until all magnetic steel slots on the iron core 60 are fully inserted with magnetic steel, and the insertion of magnetic steel in the iron core 60 is completed. The second transfer device 33 transfers the iron core 60 with the inserted magnetic steel out.

[0049] The magnet inserting mechanism 30 also includes an IX camera, which is used to take a picture of the upper end surface of the iron core 60 after all the magnets are inserted into the iron core 60 to detect whether the magnets protrude from the end surface of the iron core 60.

In addition, the glue coating mechanism 40 also includes an alcohol barrel 46 and an anti-drip glue assembly 47, and the alcohol barrel 46 is located beside the weighing assembly 41; the anti-drip glue assembly 47 includes a glue drip seat 471 and an anti-drip glue driving cylinder 472 that drives the glue drip seat 471 to move forward and backward, the glue drip seat 471 is installed at the output end of the anti-drip glue driving cylinder 472, and the glue drip seat 471 is provided with a glue drip hole 473 for glue flow, and the lower end of the glue drip hole 473 is connected to a pipeline to flow the glue collected in the glue drip seat 471 to other collection containers. When the glue coating mechanism 40 is not used for a long time, the anti-drip glue driving cylinder 472 drives the glue dripping seat 471 to move forward, and the glue dripping seat 471 is located under the glue gun 431 to prevent the glue in the glue gun 431 from dripping onto the equipment platform.

[0051] In addition, the glue coating mechanism 40 also has a glue coating detection camera 48 for detecting the iron core 60 after glue coating to determine whether there is glue breakage at the glue coating position. The glue coating detection camera 48 is installed on the glue coating bracket 44.

[0052] The weighing assembly 41 is used to weigh and measure the glue discharge amount of the glue gun 431 (the amount of glue applied to one iron core 60) to determine whether the glue discharge amount is within the standard range. The glue receiving barrel 421 is used to receive the glue discharge of the glue gun 431 at intervals (glue discharge is required at intervals) to prevent the glue gun 431 from not discharging glue for a long time, resulting in the glue outlet solidifying and being unable to discharge glue. The alcohol barrel 46 is used to hold alcohol, and the glue outlet of the glue gun 431 is immersed in alcohol to prevent the glue outlet from being blocked by solidified glue. The alcohol barrel 46, the weighing assembly 41 and the glue receiving barrel 421 are arranged in order from left to right.

[0053] Before the specific glue application operation, the weighing assembly 41 is used to weigh and measure the glue output. The glue application operation is performed only after the weighing is qualified. During the glue application, the glue application lifting and lowering driving unit 432 drives the glue gun 431 to reach the top of the iron core 60, and the iron core 60 rotates. The glue gun 431 applies glue to the upper end surface of the iron core 60 in one circle, and the magnetic steel is fixed in the magnetic steel slot of the iron core 60 by glue. When not applying glue, the glue barrel 421 is discharged at a certain interval to prevent the glue from solidifying in the conveying pipeline; and, if the glue is not discharged for a long time, the glue outlet of the glue gun 431 is immersed in the alcohol barrel 46 to prevent the glue outlet from being blocked.

[0054] The handling device 50 is a robot arm having two clamps 51 mounted on the rotating spindle of the robot arm. The two clamps 51 can realize that one clamp is releasing material while the other clamp is taking away the material that has been operated, thereby achieving the purpose of rotating material exchange and improving production efficiency.

[0055] In addition, the device also has a defective product collection area 70 for collecting defective products. During the above-mentioned detection process, the detected defective products will be classified and transferred to the defective product collection area 70 by the conveying device 50.

[0056] An operating method for the magnetic steel assembly into a glue coating machine includes the following steps:

[0057] S1, the transport device 50 transports the iron core 60 to be tested to the testing mechanism 20, and the first transfer device 24 drives the first sliding seat 244 to send the iron core 60 to the testing mechanism 20 for temperature testing, outer diameter testing and shaft height testing; the iron core 60 that passes the test is transferred from the transport device 50 to the magnetic steel insertion mechanism 30;

[0058] S2, the magnetic steel loading assembly 31 loads the magnetic steel, and the magnetic steel inserting assembly 32 inserts the magnetic steels into the iron core 60 one by one;

[0059] S3, the iron core 60 after the magnetic steel is inserted is transferred from the transport device 50 to the glue coating mechanism 40;

[0060] S4, the glue coating mechanism 40 performs glue coating operation on the position where the magnetic steel is inserted on the iron core 60, and weighs and detects the glue amount in the glue gun 431 before gluing.

[0061] The design focus of the present invention is that by integrating the detection mechanism, the magnetic steel insertion mechanism, the glue coating mechanism and the handling device on the frame to form a magnetic steel assembly glue coating machine, the magnetic steel assembly glue coating machine can realize the fully automated operation of iron core feeding, detection, magnetic steel feeding, magnetic steel assembly and glue coating, effectively improving the motor assembly efficiency; and the outer diameter detection component and the shaft height detection component are integrated into one body, realizing the synchronous detection of the outer diameter and shaft height of the iron core, reducing the material handling process back and forth, and improving the detection efficiency. In addition, the magnetic steel insertion mechanism can directly insert the magnetic steel into the iron core, simplifying the operation steps and mechanism of magnetic steel insertion, saving the process, further improving the product production efficiency, and reducing the production cost.

[0062] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
