Description

Technical Field

[0001] The present invention relates to the technical field of intelligent detection equipment, and in particular to an intelligent detection equipment for motor components of a new energy vehicle. Background Art

[0002] With the popularization of clean energy represented by electricity and power batteries, various new energy technologies have begun to appear and be put into use. As a result, the transformation of transportation energy and power systems has gradually accelerated, and new energy vehicles have begun to enter the public eye.

[0003] In my country, many new energy vehicle companies have emerged in recent years, and the manufacturing industry related to new energy vehicles has also made great progress. However, despite this, the gap in the market for new energy vehicle supporting parts is still very large. Combined with this market situation, how to further expand their own production scale and improve production efficiency has become a major problem that plagues various manufacturers at this stage.

[0004] Taking the permanent magnet synchronous motor, a core component in new energy vehicles, as an example, it is mainly composed of components such as stators, stators and end covers, and the entire processing process involves many links. In order to ensure the quality of the final product, targeted testing is required in the production and processing links of each component. For example, the relevant detection operations for stator products composed of multiple silicon steel sheets include pressurized height measurement (parallelism), visual recognition of directional characteristics, outer diameter detection, laser coding, visual detection and flatness detection. In the prior art, the stator lamination detection method for stator products generally adopts liquid penetration for detection. However, when detecting the stator lamination, there are not only recessed areas but also raised areas on its surface, and the liquid penetration detection can only inspect the recesses of the stator laminations, so the applicability is poor. Therefore, there is an urgent need for an intelligent detection equipment for new energy vehicle motor components to solve such problems. Summary of the invention

[0022] Preferably, the inner cavities of the detection column and the detection head are hollow and interconnected, a liquid inlet hole is provided on the upper part of the side wall of the detection column, the inner cavity of the liquid inlet hole is provided with a one-way water valve whose outlet is to the inner cavity of the detection column, the liquid inlet holes are inclined and there are 6 in total, and a one-way water valve whose outlet is to the outside is provided at the outlet of the detection head.

[0028] Compared with the prior art, the present invention has the following beneficial effects:

[0029] 1. When the invention detects the surface flatness of the stator laminations, with the cooperation of the conveying assembly, the stator laminations can be conveyed and transported. At this time, the stator laminations are in motion compared to the vertical plate, and the detection assembly fixedly installed on the vertical plate can realize the function of detecting the entire double sides of the stator laminations. When the detection head detects that there is a concave damage on the stator laminations, the dilute hydrochloric acid in the detection column will flow out from the outlet of the detection head and deposit in the concave of the stator laminations, so as to achieve slight corrosion of the stator laminations and produce yellow-green crystals. On the one hand, it plays a marking role on the concave part of the stator laminations, which is convenient for the workers to quickly find the damaged parts when repairing the stator laminations in the later stage. On the other hand, after the stator laminations are corroded by the dilute hydrochloric acid, multiple scratches will be produced on their inner surface, which increases the contact area between the concave part of the stator laminations and the repair liquid during subsequent repairs, and effectively improves the workers' efficiency in repairing the damaged parts of the stator laminations.

[0030] 2. In the present invention, when the detection head detects that there is convex damage on the stator lamination, under the limiting action of the limit block, the detection column still remains in the original position in the inner cavity of the buffer box. At this time, the stator lamination will press the detection head upward, so that the dilute hydrochloric acid marking liquid inside the detection head is discharged from the outlet, which can contact and react with the convex part of the stator lamination to produce grooves. The dilute hydrochloric acid marking liquid can corrode the convex part on the stator lamination, and the surrounding part will become soft, so as to facilitate the subsequent workers to flatten the convex part when repairing the stator lamination.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] See also Figure 1-Figure 9 , the present invention provides a technical solution for intelligent detection equipment of motor components of new energy vehicles:

[0043] An intelligent detection device for motor components of new energy vehicles includes a base 1, and a conveying assembly 2 arranged on the left and right sides of the base 1, and also includes:

[0044] Stator laminations 3, the stator laminations 3 are arranged between the conveying components 2 on the front and rear sides, the front and rear side walls of the base 1 are fixedly mounted with upright plates 4, the side walls of the upright plates 4 are fixedly mounted with buffer boxes 5, and the end surfaces of the buffer boxes 5 are fixedly mounted with function boxes 6;

[0045] A detection component 7, which is disposed in the inner cavity of the buffer box 5 and is used to detect the surface of the stator laminations 3;

[0046] A marking component 8, which is disposed on a side wall of the function box 6 and is used to mark the position of a defect on the stator lamination 3;

[0047] The cleaning component 9 is arranged in the inner cavity of the function box 6 , and is used to blow away impurities on the stator laminations 3 .

[0048] Furthermore, the conveying assembly 2 includes two conveying rollers 21, each of which is equipped with a driving motor. The two conveying rollers 21 rotate in opposite directions at the same speed when working. The two conveying rollers 21 are both in contact with the stator laminations 3, and the two conveying rollers 21 are symmetrical to each other about the center plane of the base 1.

[0049] It should be noted that when the surface flatness of the stator lamination 3 is inspected, the worker first places the stator lamination 3 between the two conveying rollers 21 and synchronously runs the built-in drive motor. At this time, the two conveying rollers 21 will rotate in different directions at the same speed to squeeze and feed the stator lamination 3. At this time, the entire conveying assembly 2 can realize the function of conveying and feeding the stator lamination 3 to the right.

[0050] Further, the detection assembly 7 includes a sealing plate 71 slidably mounted in the inner cavity of the buffer box 5, and a detection spring 72 fixedly mounted on the upper end surface of the sealing plate 71, a detection column 73 is fixedly mounted on the lower end surface of the sealing plate 71, a detection head 74 is slidably mounted on the lower part of the side wall of the detection column 73, and a buffer spring 75 is fixedly mounted on the side wall of the detection head 74;

[0051] One end of the detection spring 72 away from the sealing plate 71 is fixedly connected to the top surface of the inner cavity of the buffer box 5, the detection column 73 is slidably connected to the buffer box 5 and the function box 6, and one end of the buffer spring 75 away from the detection head 74 is fixedly installed on the side wall of the detection column 73. The lower end surface of the detection head 74 is set to a smooth spherical surface, and a limit block 51 is fixedly installed on the side wall of the inner cavity of the buffer box 5.

[0052] It should be noted that, as the stator lamination 3 continues to move to the right, the stator lamination 3 is in motion compared to the vertical plate 4, and the detection head 74 will slide on the side wall of the stator lamination 3, so that the detection component 7 fixedly installed on the vertical plate 4 can realize the flatness detection of the entire double-sided surface of the stator lamination 3. When the detection head 74 detects that there is a concave damage on the stator lamination 3, at this time, under the elastic force of the detection spring 72, the detection spring 72 will squeeze the sealing plate 71 to make the detection column 73 move downward continuously, so that the detection head 74 installed on the detection column 73 also moves downward, and then the detection head will slide to the concave part of the stator lamination 3 at this time.

[0053] Furthermore, the marking assembly 8 includes a liquid storage box 81 fixedly mounted on the side wall of the functional box 6, the liquid storage box 81 is fixed and connected to the buffer box 5 through a pipe 82, a one-way water valve with an outlet to the inner cavity of the buffer box 5 is provided at the pipe 82, the inner cavity of the liquid storage box 81 is filled with dilute hydrochloric acid marking liquid, and the inner cavity of the liquid storage box 81 is connected to the outside;

[0054] The inner cavities of the detection column 73 and the detection head 74 are hollow and interconnected. A liquid inlet hole 731 is provided on the upper part of the side wall of the detection column 73. The inner cavity of the liquid inlet hole 731 is provided with a one-way water valve whose outlet is toward the inner cavity of the detection column 73. There are 6 liquid inlet holes 731 in an inclined shape. A one-way water valve whose outlet is toward the outside is provided at the outlet of the detection head 74.

[0055] It should be noted that, as the detection column 73 continuously slides downward, the effective volume of the lower part of the inner cavity of the buffer box 5 will continue to decrease, so that the pressure of the dilute hydrochloric acid marking liquid in the buffer box 5 will be significantly increased, and continuously enter the inner cavity of the detection column 73 through the liquid inlet hole set on the detection column 73, and finally be discharged from the outlet of the detection head 74. At this time, the dilute hydrochloric acid can be deposited in the depression of the stator lamination 3, and slightly corrode the depression of the stator lamination 3 to produce yellow-green crystals (the main material of the stator lamination 3 is silicon steel sheet, which can react with dilute hydrochloric acid to generate ferrous chloride and hydrogen, wherein the ferrous chloride is yellow-green). Through the special display of color, on the one hand, it can play a role in the depression of the stator lamination 3. The marking function facilitates the workers to quickly find and repair the damaged parts of the stator lamination 3. On the other hand, after the stator lamination 3 is corroded by dilute hydrochloric acid, multiple scratches will be produced on the surface of the concave part of the stator lamination 3, so as to increase the contact area between the concave part of the stator lamination 3 and the repair liquid in the subsequent repair, thereby effectively improving the workers' repair efficiency of the damaged parts of the stator lamination 3. When the detection head 74 passes through the concave area of ​​the stator lamination 3, the detection spring 72 is reset, and the detection head 74 will return to the surface of the stator lamination 3, so that the dilute hydrochloric acid marking liquid in the liquid storage box 81 can supplement the liquid pressure in the lower part of the inner cavity of the buffer box 5 through the pipeline 82, so that the entire detection assembly 7 can be used repeatedly.

[0056] When the detection head 74 detects that there is a convex damage on the stator lamination 3, under the limiting action of the limit block 51, the detection column 73 still remains in the original position of the inner cavity of the buffer box 5, so that the extrusion force of the stator lamination 3 on the detection head 74 will cause the detection head 74 to move toward the upper part of the side wall of the detection column 73, and the buffer spring 75 will be compressed. At this time, the effective total volume of the detection head 74 and the detection column 73 will become smaller, and the pressure of the internal dilute hydrochloric acid marking liquid will increase significantly, and finally it can be discharged through the detection head 74 to achieve corrosion of the convexity on the stator lamination 3. The yellow-green crystals produced in the same way are used The marking function is realized by the dilute hydrochloric acid marking liquid, and the corroded part of the protrusion on the stator lamination 3 can be contacted and reacted with the protrusion of the stator lamination 3 to produce grooves, so as to facilitate subsequent workers to flatten the protrusion when repairing the stator lamination 3. When the detection head 74 passes through the protrusion position of the stator lamination 3, the buffer spring 75 is reset. At this time, the dilute hydrochloric acid marking liquid in the buffer box 5 can also supplement the internal pressure of the detection column 73 through the liquid inlet pipe 731, and the entire device can also realize the function of repeatedly detecting and marking the protrusion damage on the stator lamination 3.

[0057] Furthermore, the cleaning assembly 9 includes a pressure storage chamber 91 arranged on both sides of the function box 6, a screw rod 92 is rotatably installed in the inner cavity of the pressure storage chamber 91, a sliding plate 93 is threadedly installed on the side wall of the screw rod 92, a cleaning fan 94 is fixedly installed on the peripheral end surface of the screw rod 92, and an air pipe 95 is arranged on the side of the lower end surface of the function box 6 close to the detection column 73;

[0058] The thread lead angle of the spiral rod 92 is greater than the equivalent friction angle of the sliding plate 93. The inner cavity of the sliding plate 93 is provided with a magnet. A strong magnetic plate is provided on the side wall of the detection column 73 at the same horizontal position as the sliding plate 93. The opposite magnetic poles of the magnet and the strong magnetic plate are opposite. The sliding plate 93 slides in the inner cavity of the side wall pressure storage chamber 91. A plurality of exhaust holes are provided on the right inner cavity of the pressure storage chamber 91. A reset spring 931 is fixedly installed on the right side wall of the sliding plate 93, and the other end of the reset spring 931 is fixed on the inner wall of the pressure storage chamber 91.

[0059] It should be noted that when the detection column 73 continuously slides downward, the strong magnetic plate arranged on the side wall of the detection column 73 will also move downward accordingly. Since the strong magnetic plate and the magnet are not in the same plane at this time, under the elastic force of the return spring 931, the sliding plate 93 will continuously move toward the left side of the inner cavity of the pressure storage chamber 91, and continuously squeeze the air on the left side of the inner cavity of the pressure storage chamber 91. At this time, the rapid airflow will continuously spray downward through the air pipe 95. The air blown out of the air pipe 95 located on the rear side of the movement direction of the stator stack 3 can blow the dilute hydrochloric acid in the depression of the stator stack 3, accelerate its volatilization in the air, and avoid the stator stack 3 being penetrated due to excessive dilute hydrochloric acid content. The airflow blown out of the air pipe 95 located in the front side of the moving direction of the stator lamination 3 can be blown off with relatively strong force the yellow-green crystals that may be adhered to the detection head 74, so as to ensure the quality of the subsequent flatness detection of the stator lamination 3 by the entire detection assembly 7. At the same time, since the thread lead angle of the spiral rod 92 is greater than the equivalent friction angle of the sliding plate 93, the spiral rod 92 will also be continuously rotated at this time, and the cleaning fan 94 fixed thereon will also be rotated at a high speed to realize the function of blowing off the dust on the stator lamination 3, ensuring that the dust will not react with the dilute hydrochloric acid, and further improving the quality of the surface flatness detection of the stator lamination 3 by the entire device.

[0060] Working principle: When inspecting the surface flatness of the stator lamination 3, the worker first places the stator lamination 3 between the two conveying rollers 21 and runs the built-in drive motors synchronously. At this time, the two conveying rollers 21 will rotate in opposite directions at the same speed to squeeze and feed the stator lamination 3, so that the entire conveying assembly 2 can now realize the function of conveying and feeding the stator lamination 3 to the right;

[0061] As the stator lamination 3 continues to move to the right, the stator lamination 3 is in motion compared to the vertical plate 4, and the detection head 74 will slide on the side wall of the stator lamination 3, so that the detection component 7 fixedly installed on the vertical plate 4 can realize the flatness detection of the entire double-sided surface of the stator lamination 3. When the detection head 74 detects that there is a concave damage on the stator lamination 3 (such as Figure 7 , 8 As shown), at this time, under the elastic force of the detection spring 72, the detection spring 72 will squeeze the sealing plate 71 to make the detection column 73 move downward continuously, so that the detection head 74 installed on the detection column 73 also moves downward, and then the detection head will slide to the concave part of the stator lamination 3 at this time;

[0062] As the detection column 73 continues to slide downward, the effective volume of the lower part of the inner cavity of the buffer box 5 will continue to decrease, so that the pressure of the dilute hydrochloric acid marking liquid in the buffer box 5 will be significantly increased, and will continuously enter the inner cavity of the detection column 73 through the liquid inlet hole set on the detection column 73, and finally be discharged from the outlet of the detection head 74. At this time, the dilute hydrochloric acid can be deposited in the depression of the stator lamination 3, and the depression of the stator lamination 3 is slightly corroded to produce yellow-green crystals (the main material of the stator lamination 3 is silicon steel sheet, which can react with dilute hydrochloric acid to generate ferrous chloride and hydrogen, wherein the ferrous chloride is yellow-green). Through the special display of color, on the one hand, it can play a marking role on the depression of the stator lamination 3. , which makes it convenient for the workers to quickly find and repair the damaged parts of the stator laminations 3. On the other hand, after the stator laminations 3 are corroded by dilute hydrochloric acid, multiple scratches will be produced on the surface of the concave parts, which increases the contact area between the concave parts of the stator laminations 3 and the repair liquid during subsequent repairs, thereby effectively improving the workers' repair efficiency of the damaged parts of the stator laminations 3. When the detection head 74 passes through the concave area of ​​the stator laminations 3, the detection spring 72 is reset, and the detection head 74 will return to the surface of the stator laminations 3, so that the dilute hydrochloric acid marking liquid in the liquid storage box 81 can supplement the liquid pressure in the lower part of the inner cavity of the buffer box 5 through the pipeline 82, so that the entire detection assembly 7 can be used repeatedly.

[0063] When the detection column 73 continuously slides downward, the strong magnetic plate arranged on the side wall of the detection column 73 will also move downward accordingly. Since the strong magnetic plate and the magnet are not in the same plane at this time, under the elastic force of the return spring 931, the sliding plate 93 will continuously move toward the left side of the inner cavity of the pressure storage chamber 91, and continuously squeeze the air on the left side of the inner cavity of the pressure storage chamber 91. At this time, the rapid airflow will continuously spray downward through the air pipe 95. The air blown out of the air pipe 95 located on the rear side of the movement direction of the stator stack 3 can blow the dilute hydrochloric acid in the depression of the stator stack 3, accelerate its volatilization in the air, and avoid the penetration of the stator stack 3 due to excessive dilute hydrochloric acid content. The airflow blown out of the air pipe 95 located in the front side of the moving direction of the stator lamination 3 can be blown off the yellow-green crystals that may be adhered to the detection head 74 with relatively strong force, so as to ensure the quality of the subsequent flatness detection of the stator lamination 3 by the entire detection assembly 7. At the same time, since the thread lead angle of the spiral rod 92 is greater than the equivalent friction angle of the sliding plate 93, the spiral rod 92 will also be continuously rotated at this time, and the cleaning fan 94 fixed thereon will also be rotated at a high speed to realize the function of blowing off the dust on the stator lamination 3, ensuring that the dust will not react with the dilute hydrochloric acid, and further improving the quality of the surface flatness detection of the stator lamination 3 by the entire device;

[0064] When the detection head 74 detects that there is a convex damage on the stator lamination 3 (such as Figure 7 , 9As shown in the figure, under the limiting action of the limit block 51, the detection column 73 still remains in the original position of the inner cavity of the buffer box 5, so that the extrusion force of the stator stack 3 on the detection head 74 will cause the detection head 74 to move toward the upper part of the side wall of the detection column 73, and the buffer spring 75 will be compressed. At this time, the effective total volume of the detection head 74 and the detection column 73 will become smaller, and the pressure of the internal dilute hydrochloric acid marking liquid will increase significantly, and finally it can be discharged through the detection head 74 to realize the corrosion of the protrusions on the stator stack 3. Similarly, the yellow-green crystals produced are used for marking, and the dilute hydrochloric acid marking liquid The acid marking liquid can cause the corroded part of the protrusion on the stator lamination 3 to contact and react with the protrusion of the stator lamination 3 to produce grooves, so as to facilitate subsequent workers to flatten the protrusion when repairing the stator lamination 3. When the detection head 74 passes through the protrusion position of the stator lamination 3, the buffer spring 75 is reset. At this time, the dilute hydrochloric acid marking liquid in the buffer box 5 can also supplement the internal pressure of the detection column 73 through the liquid inlet pipe 731, and the entire device can also realize the function of repeatedly detecting and marking the protrusion damage on the stator lamination 3.
