Description

Technical Field

[0001] The present invention relates to the technical field of stator core processing equipment, and particularly relates to a laser engraving device for stator cores. Background Art

[0002] As a core component of an electric motor, the surface of a stator core needs to be engraved with information such as serial numbers, brand logos, QR codes, etc. to meet the requirements of quality traceability and process management. Currently, the following engraving techniques are mainly used in the industry: mechanical stamping engraving, chemical etching, and traditional laser engraving.

[0003] For laser engraving, since the laser welding engraving method is relatively traditional and mostly uses manual loading and unloading, manual loading and unloading not only affects the processing efficiency of the stator core, but also the positioning accuracy during the processing process is overly dependent on manual experience. For workers with shorter working years, it is easy to cause the engraving position to exceed the tolerance due to misplacement, so further improvement is needed on this basis. Summary of the Invention

[0004] To solve the technical problems existing in the above background art, the present invention proposes a laser engraving device for stator cores.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A laser engraving device for stator cores, characterized by comprising:

[0007] A base, on which a first conveying track and a second conveying track are provided. The first conveying track and the second conveying track are arranged perpendicular to each other. At the intersection of the first conveying track and the second conveying track, there is a base for placing the stator core. On the base, there is a first opening groove arranged parallel to the second conveying track;

[0008] A cylinder, which is installed on the base. The cylinder is connected to a pusher assembly, and the cylinder can drive the pusher assembly to move along the path of the second conveying track;

[0009] A clamping rod, which is hinged to the base. The clamping rod is provided with a second opening groove. A column is connected to the pusher assembly, and the column sequentially passes through the first opening groove and the second opening groove in the vertical direction;

[0010] A laser engraving machine, which is installed on the base and is located above the base.

[0011] Preferably, the pusher assembly includes a first rod, a second rod, a first plate, a second plate, and a push plate. The first rod and the second rod are slidably mounted on the base. One end of the first rod and the second rod is connected to the first plate, and the other end of the first rod and the second rod is connected to the second plate. The push plate and the cylinder are both connected to the second plate. The first rod, the second rod, and the push plate are all in the same direction as the extension direction of the second conveying track path.

[0012] Preferably, when the stator core is conveyed to the base through the first conveying track, the cylinder drives the second plate to drive the column body to move along the path of the second conveying track, so that the first wall, the second wall of the base, and the clamping rod clamp and fix the stator core.

[0013] Preferably, when the cylinder drives the second plate to drive the push plate to push the stator core onto the second conveying track, the clamping rod is entirely located on the side of the second wall close to the first opening groove.

[0014] Preferably, the outer diameter of the column body is equal to the inner diameter of the first opening groove and the inner diameter of the second opening groove.

[0015] Preferably, the contact line between the first conveying track and the stator core, the contact surface between the second conveying track and the stator core, and the top surface of the base are flush.

[0016] Preferably, the end of the push plate away from the second plate is an arc portion, and a part of the arc portion is made of rubber material.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] Compared with the prior art, by realizing the automatic loading and unloading of the stator core during the engraving process, the processing efficiency of the stator core during the engraving process can be effectively improved. By realizing the linkage cooperation between the pusher assembly and the clamping rod, not only can the stability of the stator core during the engraving process be improved, thereby improving the engraving quality, but also the conversion between loading and unloading can be realized, making the connection between the stator core before processing, during processing, and after processing more coherent, realizing the high-efficiency processing of the stator core. Moreover, the clamping rod can be adjusted accordingly according to the different diameters of the stator core to realize the fixation, processing, and loading and unloading of different models of stator cores. Since the clamping rod, the first wall, and the second wall all form line contact with the stator core, it can also clamp and fix the stator core according to its different shapes.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0026] As Figures 1 - 5 shown, this embodiment provides a stator core laser engraving device, including:

[0027] A base 1, on which a first conveying track 2 and a second conveying track 4 are provided. The first conveying track 2 and the second conveying track 4 are arranged perpendicular to each other. At the intersection of the first conveying track 2 and the second conveying track 4, a base table 101 for placing the stator core 3 is provided. On the base 1, a first opening groove 102 arranged parallel to the second conveying track 4 is provided;

[0028] A cylinder 10, which is installed on the base 1. The cylinder 10 is connected to a pushing component, and the cylinder 10 can drive the pushing component to move along the path of the second conveying track 4;

[0029] A clamping rod 7, which is hinged to the base 1. A second opening groove 71 is provided on the clamping rod 7. A column body 51 is connected to the pushing component, and the column body 51 sequentially passes through the first opening groove 102 and the second opening groove 71 in the vertical direction;

[0030] A laser engraving machine 12, which is installed on the base 1 and is located above the base table 101.

[0031] Overall, when laser engraving processing is required for the stator core 3, the stator core 3 is conveyed along the path of the first conveying track 2 to the base 101. After the stator core 3 is located above the base 101, the cylinder 10 drives the pusher assembly to move along the path of the second conveying track 4, so that the cylinder body 51 moves along the path of the first opening groove 102. Through the sliding fit between the cylinder body 51 and the second opening groove 71, the clamping rod 7 can be rotated around the base 1, and the stator core 3 respectively forms line contact with the first wall 103, the second wall 104 on the base and the clamping rod 7, so as to fix the stator core 3. After the stator core 3 is fixed, the laser engraving machine 12 is started to complete the engraving processing of the stator core 3. After the laser engraving of the stator core 3 is completed, the cylinder 10 drives the pusher mechanism to move along the path of the second conveying track 4, so that the cylinder body 51 moves along the path of the first opening groove 102. Through the sliding fit between the cylinder body 51 and the second opening groove 71, the clamping rod 7 can be rotated around the base 1, and the clamping rod 7 is separated from the stator core 3. At the same time, the cylinder 10 drives the pusher mechanism to move along the path of the second conveying track 4 and contact the stator core 3, so as to push the stator core 3 into the second conveying track 4, and finally discharge through the second conveying track 4. In this way, continuous loading and unloading, fixing, and engraving processing of the stator core 3 can be realized by repeating this cycle.

[0032] As Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, in this embodiment, the pusher assembly includes a first rod body 5, a second rod body 6, a first plate body 8, a second plate body 11 and a push plate 9. The first rod body 5 and the second rod body 6 are slidably installed on the base 1. One end of the first rod body 5 and the second rod body 6 is connected to the first plate body 8, and the other end of the first rod body 5 and the second rod body 6 is connected to the second plate body 11. The push plate 9 and the cylinder 10 are both connected to the second plate body 11. The first rod body 5, the second rod body 6 and the push plate 9 are all in the same direction as the extension direction of the path of the second conveying track 4.

[0033] Specifically, during the process of the cylinder 10 driving the material pushing assembly to move, through the movement of the second plate body 11, the first rod body 5 and the second rod body 6 move along the path of the second conveying track 4, and the cylinder 51 on the first rod body 5 moves along the path of the first opening groove 102. When it is necessary to fix the stator core 3, through the sliding fit between the cylinder 51 and the second opening groove 71, the clamping rod 7 can be rotated around the base 1, so that the first wall 103, the second wall 104 and the clamping rod 7 form a line contact with the stator core 3, realizing the clamping and fixing of the stator core 3 during the engraving process. After the engraving process is completed, the cylinder 10 drives the second plate body 11 to move in the reverse direction, so that the first rod body 5 and the second rod body 6 move along the path of the second conveying track 4, and the cylinder 51 on the first rod body 5 moves along the path of the first opening groove 102. Through the sliding fit between the cylinder 51 and the second opening groove 71, the clamping rod 7 can be rotated around the base 1, and the clamping rod 7 is separated from the stator core 3. During the process of the clamping rod 7 being separated from the stator core 3, the cylinder 10 drives the second plate body 11 to drive the push plate 9 to move along the path of the second conveying track 4. When the whole clamping rod 7 is located on the side of the second wall 104 close to the first opening groove 102, the push plate 9 completely pushes the stator core 3 on the base 101 into the second conveying track 4, and finally the discharging of the stator core 3 is realized through the conveying of the second conveying track 4.

[0034] As Figure 1 shown, in this embodiment, when the stator core 3 is conveyed to the base 101 through the first conveying track 2, the cylinder 10 drives the second plate body 11 to drive the cylinder 51 to move along the path of the second conveying track 4, so that the first wall 103, the second wall 104 of the base 1 and the clamping rod 7 realize the clamping and fixing of the stator core 3.

[0035] Specifically, during the process of the clamping rod 7 rotating around the base 1, the first wall 103, the second wall 104 and the clamping rod 7 all form a line contact with the stator core 3. According to the principle that a triangle has stability, the stability of the stator core 3 during the engraving process can be improved, and further the quality of the engraving process of the stator core 3 can be improved. Moreover, by driving the clamping rod 7 to rotate around the base 1, different sizes of stator cores 3 can be clamped and fixed according to the different diameters of the stator cores 3, improving the overall applicable range of the device.

[0036] As Figure 3 shown, in this embodiment, when the cylinder 10 drives the second plate body 11 to drive the push plate 9 to push the stator core 3 onto the second conveying track 4, the whole clamping rod 7 is located on the side of the second wall 104 close to the first opening groove 102.

[0037] Specifically, when the cylinder 10 drives the second plate body 11 to drive the push plate 9 to push the stator core 3 onto the second conveying track 4, the whole clamping rod 7 is located on the side of the second wall 104 close to the first opening, which can prevent interference between the stator core 3 and the end of the clamping rod 7 far from the hinge point during the discharging process along the second conveying track 4, enabling the stator core 3 to pass through the second conveying track 4 smoothly.

[0038] As Figure 1 , Figure 3 and Figure 5 shown, in this embodiment, the outer diameter of the column 51 is equal to the inner diameter of the first opening groove 102 and the inner diameter of the second opening groove 71.

[0039] Specifically, the outer diameter of the column 51 being equal to the inner diameter of the first opening groove 102 and the inner diameter of the second opening groove 71 can prevent the column 51 from wobbling when sliding along the paths of the first opening groove 102 and the second opening groove 71, improving the stability of the stator core 3 during the clamping or discharging and pushing processes.

[0040] As Figure 1 and Figure 3 shown, in this embodiment, the contact line between the first conveying track 2 and the stator core 3, the contact surface between the second conveying track 4 and the stator core 3, and the top surface of the base 101 are flush.

[0041] Specifically, by making the contact line between the first conveying track 2 and the stator core 3, the contact surface between the second conveying track 4 and the stator core 3, and the top surface of the base 101 flush, it can prevent the stator core 3 from being bumped during the loading and unloading process due to the height difference, and can effectively improve the yield rate of the stator core 3.

[0042] As Figures 1 - 4 shown, in this embodiment, the end of the push plate 9 far from the second plate body 11 is an arc portion, and a part of the arc portion is made of rubber material.

[0043] Specifically, setting the end of the push plate 9 far from the second plate body 11 in the shape of an arc portion can prevent the stator core 3 from having a large path fluctuation due to the deviation of the inertial force during the pushing process, improving the stability of the stator core 3 during the conveying process, and the rubber material can effectively reduce the rigid collision between the push plate 9 and the stator core 3, providing a certain protection for the stator core 3.
