The ventilation channel steel is integrally formed with the stator punching sheet by spot welding, and its function is to form a radial air duct and ventilate and cool the stator core and the stator coil.

[0003] However, in the general welding production process of the ventilation slot plate, the welding method usually adopts single-point semi-automatic welding. However, the welding process of this welding method has low efficiency. Each welding point requires manual operation for welding, resulting in low work efficiency. Moreover, the welding quality is not easy to control. During the welding process, the workpiece needs to be held manually and aligned vertically before welding. After each piece is welded, the welding height and the consistency of the welding point size cannot be guaranteed. Summary of the Utility Model

[0005] To achieve the above object, the welding device proposed by the utility model is used to weld a slot plate and a plurality of slot pieces to form a ventilation slot plate. The welding device is characterized in that the welding device has a loading station and a welding station which are staggeredly arranged in a horizontal plane. The welding device includes:

[0006] A positioning structure, including two positioning parts which are spaced apart in the vertical direction. At least one of the two positioning parts has a moving stroke in the vertical direction. Each positioning part is rotatably arranged along an axis extending in the vertical direction and can pass through the loading station and the welding station during rotation. The two positioning parts are used to carry the slot plate and a plurality of slot pieces which are in contact with each other at the loading station and can transfer the plurality of slot pieces to the welding station; and,

[0007] A welding structure, which is located at the welding station and is used to sequentially weld the slot pieces transferred to the welding station to the slot plate.

[0008] In an embodiment, the two positioning parts include:

[0009] A fixed positioning part; used to carry the slot plate; and,

[0010] The movable positioning part is arranged above the fixed positioning part. The movable positioning part is movably arranged in the up-and-down direction and is used to move downward to clamp the slot plate together with the fixed positioning part and can position a plurality of slot pieces at the loading station.

[0011] In one embodiment, the movable positioning part includes a clamping plate. A plurality of first hole parts are arranged at intervals along the circumferential direction on the upper surface of the clamping plate. Each first hole part is used for inserting a slot piece so that the slot piece abuts against the slot plate.

[0012] In one embodiment, the plurality of first hole parts include two adjacent mating holes. When one of the two mating holes is at the loading station, the other is at the welding station.

[0013] In one embodiment, a limiting part is arranged on one of the positioning parts. The limiting part is used for contact and cooperation with the slot plate to limit the position of the slot plate in the horizontal direction.

[0014] In one embodiment, a plurality of through holes are arranged along the circumferential direction on the opposite end faces of the two positioning parts. The through holes of the positioning part located above are used for inserting slot pieces so that the slot pieces abut against the slot plate;

[0015] The welding structure includes two welding electrodes arranged at intervals in the up-and-down direction. The two welding electrodes can be respectively in the two opposite through holes in the up-and-down direction so that the corresponding slot pieces are welded to the slot plate.

[0016] In one embodiment, the two welding electrodes include a first welding electrode corresponding to the positioning part located above. Sealing parts are arranged at both opposite ends of the first welding electrode in the horizontal direction. The two sealing parts are used for sealing two adjacent through holes when the first welding electrode extends into the corresponding through hole.

[0017] In one embodiment, the welding device further has a feeding station spaced from the loading station and the welding station. The feeding station is used for storing slot pieces;

[0018] The welding device further includes a feeding structure. The feeding structure is movably arranged, and its moving stroke passes through the feeding station and the loading station. The feeding structure is used for picking up the slot pieces at the feeding station, moving them to the loading station, and placing the slot pieces on one of the positioning parts.

[0019] In one embodiment, the welding device further includes a pushing structure located below the loading station. The pushing structure includes a bearing table movably arranged in the up-and-down direction. A plurality of slot pieces stacked in the up-and-down direction are placed on the bearing table.

[0021] In the technical solution of the present utility model, when it is necessary to weld the groove plate and a plurality of groove pieces into a ventilation groove plate, the user first places the groove plate on one of the positioning parts. Then, at least one of the two positioning parts moves in the up and down direction towards the other positioning part to jointly position the groove plate. Then, a groove piece at the feeding station is fed onto the other positioning part, and this positioning part can guide and position the groove piece onto the groove plate so that the groove plate and the groove piece are in contact with each other and the relative positions of the groove plate and the groove piece are determined. After that, the two positioning parts rotate around the axis extending in the up and down direction, so that the groove piece moves out of the feeding station to enable continuous feeding of other groove pieces onto the other positioning part. Moreover, during the rotation of the two positioning parts around the axis extending in the up and down direction, when a groove piece has been sent to the welding station, the welding structure can weld the groove piece transferred to the welding station to the groove plate to complete the welding of this groove piece. After all the groove pieces are welded to the groove plate, the ventilation groove plate is obtained and the welding work is completed. At least one of the two positioning parts moves in the up and down direction away from the other positioning part to release the restriction on the ventilation groove plate and enable the ventilation groove plate to be unloaded. Such a setting ensures that during the process of the welding device welding the groove plate and a plurality of groove pieces into one body, no manual operation intervention is required for each welding point between the groove piece and the groove plate, which guarantees the welding efficiency. At the same time, by directly determining the relative positions of the groove piece and the groove plate through the two positioning parts, the welding quality can be further improved and the consistency of the welding point size can be ensured.

[0030] The present utility model provides a welding device, aiming to solve the problems of low efficiency in the welding process of the existing welding method, where each welding point requires manual operation, resulting in low work efficiency, and it is not easy to control the welding quality. During the welding process, the workpiece needs to be held by hand and aligned vertically for welding. After each piece is welded, the welding height and the consistency of the welding point size cannot be guaranteed.

[0031] Please refer to Figure 1, in an embodiment of the present utility model, the welding device 100 is used to weld a groove plate and a plurality of groove pieces to form a ventilation groove plate. It is characterized in that the welding device 100 has a loading station and a welding station that are staggered in the horizontal plane. The welding device 100 includes a positioning structure 1 and a welding structure 2. The positioning structure 1 includes two positioning parts 11 that are spaced apart in the vertical direction. At least one of the two positioning parts 11 has a moving stroke in the vertical direction. Each positioning part 11 is rotatably arranged along an axis extending in the vertical direction and can pass through the loading station and the welding station during rotation. The two positioning parts 11 are used to carry the groove plate and a plurality of groove pieces that are in contact with each other at the loading station and can transfer the plurality of groove pieces to the welding station. The welding structure 2 is located at the welding station and is used to sequentially weld the groove pieces flowing to the welding station to the groove plate.

[0032] In the technical solution of the present utility model, when it is necessary to weld a groove plate and a plurality of groove pieces into a ventilation groove plate, the user first places the groove plate on one of the positioning parts 11. Then, at least one of the two positioning parts 11 moves in the vertical direction towards the direction close to the other positioning part 11 to jointly position the groove plate. Then, a groove piece at the loading station is loaded onto the other positioning part 11. This positioning part 11 can guide and position the groove piece onto the groove plate so that the groove plate and the groove piece are in contact with each other and determine the relative positions of the groove plate and the groove piece. After that, the two positioning parts 11 rotate along the axis extending in the vertical direction to move the groove piece out of the loading station so that other groove pieces can continue to be loaded onto the other positioning part 11. Moreover, during the rotation of the two positioning parts 11 along the axis extending in the vertical direction, when a groove piece has been sent to the welding station, the welding structure 2 can weld the groove piece flowing to the welding station to the groove plate to complete the welding of this groove piece. After all the groove pieces are welded to the groove plate, the ventilation groove plate is obtained and the welding work is completed. At least one of the two positioning parts 11 moves in the vertical direction towards the direction away from the other positioning part 11 to release the restriction on the ventilation groove plate and can unload the ventilation groove plate. Such a setting ensures that during the process of the welding device 100 welding the groove plate and a plurality of groove pieces into one body, no manual operation intervention is required for each welding point between the groove piece and the groove plate, which guarantees the welding efficiency. At the same time, by directly determining the relative positions of the groove piece and the groove plate through the two positioning parts 11, the welding quality can be further improved and the consistency of the welding point size can be ensured.

[0033] Specifically, in the present utility model, the positioning part 11 arranged on the lower side is used to carry the groove plate, and the positioning part 11 arranged on the upper side is used to guide and position the relative positions of the groove piece and the groove plate.

[0034] It can be understood that the present utility model does not limit which specific positioning portion 11 has an up-and-down movement stroke. For example, in an embodiment of the present utility model, one of the positioning portions 11 provided on the upper side has an up-and-down movement stroke, while one of the positioning portions 11 provided on the lower side is fixedly arranged in the up-and-down direction. With such a setting, after the positioning portion 11 provided on the lower side bears the groove plate, the positioning portion 11 provided on the upper side can move downward to position the groove plate together with the positioning portion 11 provided on the lower side.

[0035] In another embodiment of the present utility model, one of the positioning portions 11 provided on the lower side has an up-and-down movement stroke, while the positioning portion 11 provided on the upper side is fixedly arranged in the up-and-down direction. Thus, after the positioning portion 11 provided on the lower side bears the groove plate, it can also move upward to position the groove plate together with the positioning portion 11 provided on the upper side.

[0036] Similarly, in yet another embodiment of the present utility model, both of the positioning portions 11 have an up-and-down movement stroke. With such a setting, after the positioning portion 11 provided on the lower side bears the groove plate, the two positioning portions 11 can simultaneously move in the up-and-down direction towards the other positioning portion 11, thereby jointly positioning the groove plate.

[0037] Specifically, in an embodiment of the present utility model, the two positioning portions 11 clamp the groove plate together to limit the offset of the position of the groove plate.

[0038] Of course, before the two positioning portions 11 jointly clamp and position the groove plate, it is also necessary to ensure the accuracy of the feeding position during the process of feeding the groove plate onto one of the positioning portions 11. In an embodiment of the present utility model, a limiting portion is provided on one of the positioning portions 11, and the limiting portion is used for contact and cooperation with the groove plate to limit the position of the groove plate in the horizontal direction. With such a setting, when the groove plate is fed onto this positioning portion 11, the limiting portion can directly limit the position of the groove plate in the horizontal direction to ensure the accuracy of the feeding position of the groove plate, thereby guaranteeing the quality of subsequent welding work.

[0039] It can be understood that the present utility model does not limit the specific number of the limiting portions provided. In an embodiment of the present utility model, only one limiting portion is provided. With such a setting, one limiting portion can also ensure the ability to limit the position of the groove plate in the horizontal direction; while in another embodiment of the present utility model, a plurality of limiting portions are provided, and the plurality of limiting portions are spaced apart in the horizontal direction. Thus, the plurality of limiting portions can not only limit the position of the groove plate in the horizontal direction, but also jointly limit the angle of the groove plate in the horizontal direction, thereby further ensuring the accuracy of the feeding position of the groove plate.

[0040] Specifically, in this embodiment, a plurality of limiting portions are provided and are all arranged on the positioning portion 11 located on the lower side.

[0041] In addition, the present utility model does not limit the specific form of the limiting portion. In an embodiment of the present utility model, the limiting portion can be set as a limit pin. In this way, when the groove plate is fed onto the corresponding fixing portion, the limit pin can be inserted into the groove plate to limit the position of the groove plate in the horizontal direction.

[0042] In another embodiment of the present utility model, the limiting portion can also be set as a buckle, and the buckle can be clamped with the peripheral side surface of the groove plate. In this way, the position of the groove plate in the horizontal direction can also be limited.

[0043] In other embodiments of the present utility model, the limiting portion can also be set as other structures that limit the position of the groove plate in the horizontal direction. When actually setting, it can be selected according to requirements.

[0044] In a specific embodiment of the present utility model, the two positioning portions 11 include a fixed positioning portion 111 and a movable positioning portion 112. The fixed positioning portion 111 is used for carrying the groove plate. The movable positioning portion 112 is arranged above the fixed positioning portion 111. The movable positioning portion 112 is movably arranged in the up and down direction. The movable positioning portion 112 is used to move downward to clamp the groove plate together with the fixed positioning portion 111 and can position a plurality of groove pieces at the loading station.

[0045] In order to ensure the stability of the relative position of the movable positioning portion 112 for positioning the groove piece and the groove plate, in an embodiment of the present utility model, the movable positioning portion 112 includes a clamping plate. A plurality of first hole portions 12 are arranged at intervals along the circumference on the upper surface of the clamping plate. Each first hole portion 12 is used for inserting the groove piece so that the groove piece abuts against the groove plate. In this embodiment, when a groove piece at the loading station is lifted onto the movable positioning portion 112, specifically, the groove piece is inserted into the first hole portion 12 at the loading station and the groove piece abuts against the groove plate. The setting of the first hole portion 12 can ensure the smooth abutment of the groove piece and the groove plate. At the same time, it can also provide a guiding effect during the insertion process of the groove piece to ensure the relative position of the groove piece and the groove plate.

[0046] It should be noted that the present utility model does not limit the specific structural form of the first hole portion 12. In an embodiment of the present utility model, the first hole portion 12 may be provided as a straight hole. With such a setting, it can ensure that the slot piece is perpendicular to the slot plate. In another embodiment of the present utility model, the first hole portion 12 may also be provided with a first hole section and a second hole section that communicate in the up-and-down direction. The aperture of the first hole section is set as a tapered hole that gradually decreases from top to bottom. In this way, as long as it is ensured that the lower hole opening of the second hole section can correspond to the solder joint of the slot plate, it can ensure that the slot piece is perpendicular to the slot plate. In actual setting, it can be selected according to requirements.

[0047] Certainly, the present utility model also does not limit the distance between the loading station and the welding station. Generally, there are multiple solder joints on the slot plate, and multiple first hole portions 12 are provided corresponding to the multiple solder joints. Each slot piece is inserted into one of the first hole portions 12. Thus, in an embodiment of the present utility model, the multiple first hole portions 12 include two adjacent mating holes. When one of the two mating holes is at the loading station, the other is at the welding station. With such a setting, after the slot piece at the loading station is inserted into the corresponding mating hole, the movable positioning portion 112 and the fixed positioning portion 111 rotate together along the axis extending in the up-and-down direction to transfer the mating hole from the loading station to the welding station, and at the same time transfer the other mating hole to the loading station to wait for the loading of the next slot piece. The welding structure 2 can weld the slot piece and the slot plate at the welding station, so that the welding work and the loading work are carried out simultaneously to ensure the welding efficiency of the welding device 100.

[0048] In another embodiment of the present utility model, the plurality of first hole portions 12 may also include at least one transition hole, and two mating holes provided on opposite sides of the transition hole. When one of the two mating holes is at the loading station, the other is at the welding station. With such a setting, after the slot piece at the loading station is inserted into the corresponding mating hole, the movable positioning portion 112 and the fixed positioning portion 111 rotate together along the axis extending in the up and down direction to transfer the mating hole from the loading station to the welding station. During the rotation of the movable positioning portion 112 and the fixed positioning portion 111, the transition hole will first be transferred to the loading station. At this time, the movable positioning portion 112 and the fixed positioning portion 111 stop rotating, and the slot piece at the loading station will be inserted into the transition hole. After the loading is completed, the movable positioning portion 112 and the fixed positioning portion 111 continue to rotate until the mating hole with the slot piece inserted is transferred to the welding station for welding work. At this time, the other mating hole moves to the loading station for loading work. With such a setting, the distance between the loading station and the welding station can be increased, thereby avoiding interference between the loading work of the slot piece and the slot plate and the welding work, and thus affecting the working stability of the welding device 100.

[0049] In addition, to improve the ability of the welding structure 2 to weld the slot plate and the slot piece, in one embodiment of the present utility model, the welding structure 2 includes two welding electrodes spaced apart in the up and down direction. Correspondingly, a plurality of through holes 13 arranged circumferentially are formed in the opposite end faces of the two positioning portions 11. The through holes 13 of the positioning portion 11 located above are used for inserting the slot piece so that the slot piece abuts against the slot plate. The two welding electrodes can be respectively located in the two through holes 13 opposite to each other in the up and down direction, so that the corresponding slot piece is welded to the slot plate. With such a setting, when the welding structure 2 needs to weld the slot piece and the slot plate into one body, the two welding electrodes can respectively extend into the corresponding through holes 13 to respectively abut against the slot piece and the slot plate. The welding current melts the convex points of the slot piece, and after the solder joints are melted by heat, they are melted into one body with the slot plate. After the welding work of the slot piece is completed, the two welding electrodes move up and down again to disengage from the corresponding through holes 13, so as to allow the two positioning portions 11 to rotate along the axis extending in the up and down direction to switch the other through hole 13 to the welding station, thereby performing the welding work of the next slot piece.

[0050] It can be understood that the first hole portion 12 includes the through hole 13 provided on the positioning portion 11 located on the upper side.

[0051] It should be further noted that when the welding structure 2 welds the slot plate and the slot piece at the welding station into one body, the welding current generated by the welding structure 2 will generate a magnetic field, and this magnetic field will drive the un-welded slot piece in an adjacent through hole 13 to move, resulting in the phenomenon that the un-welded slot piece pops out from the corresponding pupil, reducing the welding quality. Therefore, in an embodiment of the present invention, the two welding electrodes include a first welding electrode corresponding to the positioning portion 11 located above. The first welding electrode is provided with blocking members 21 at both horizontally opposite ends. The two blocking members 21 are used to block the two adjacent through holes 13 when the first welding electrode extends into the corresponding through hole 13. With such a setting, when the welding structure 2 needs to weld the slot plate and the slot piece at the welding station into one body, the first welding electrode extends into the corresponding through hole 13. Correspondingly, the two blocking members 21 can block the two through holes 13 adjacent to this through hole 13, thereby restricting the un-welded slot piece within the corresponding through hole 13 to prevent the un-welded slot piece from popping out of this through hole 13 and affecting the welding quality.

[0052] It can be understood that the blocking members 21 are provided at both horizontally opposite ends of the first welding electrode. In this way, it can be ensured that when the two positioning portions 11 rotate in any direction, the blocking members 21 can block the through hole 13 in which the un-welded slot piece is inserted to ensure the blocking performance of the blocking members 21.

[0053] Furthermore, to ensure that the slot piece at the loading station can be accurately loaded to the corresponding welding point position each time, in an embodiment of the present invention, the welding device 100 further has a feeding station spaced from the loading station and the welding station. The feeding station is used for storing slot pieces. The welding device 100 further includes a loading structure 3. The loading structure 3 is movably arranged, and its moving stroke passes through the feeding station and the loading station. The loading structure 3 is used to pick up the slot piece at the feeding station, move it to the loading station, and place the slot piece on one of the positioning portions 11. With such a setting, manual loading of slot pieces is cancelled, and through the form of mechanical automatic loading, the accuracy of the loading position of the slot piece is ensured, thereby ensuring the subsequent welding quality.

[0054] It should be noted that the present invention does not limit the specific structural form of the loading structure 3. In an embodiment of the present invention, the loading structure 3 includes a two-axis manipulator. In this way, after the two-axis manipulator picks up the slot piece at the feeding station, it carries the slot piece and moves to the upper part of the loading station. Then, it moves downward partially to place the slot piece at the corresponding welding point position on one of the positioning portions 11 to complete the loading station.

[0055] In another embodiment of the present utility model, the loading structure 3 can also be configured as a worm and worm gear structure and a picking part movably arranged on the worm and worm gear structure in the up and down direction. With such a setting, the normal progress of the loading work can also be ensured.

[0056] Of course, in other embodiments of the present utility model, the loading structure 3 can also be configured as other structures that can move the groove piece from the feeding station to the loading station and place it on one of the positioning parts 11. When actually setting, it can be selected according to requirements.

[0057] Correspondingly, to ensure that there is always a groove piece stored at the feeding station and to ensure the smoothness of the picking of the groove piece by the loading structure 3 at the feeding station, in an embodiment of the present utility model, the welding device 100 further includes a top feeding structure 4 located below the loading station. The top feeding structure 4 includes a carrying platform 41 movably arranged in the up and down direction. A plurality of groove pieces stacked in the up and down direction are placed on the carrying platform 41. The carrying platform 41 moves upward so that the groove piece at the top is at the feeding station. In this way, whenever the loading structure 3 picks up the groove piece at the feeding station, the top feeding structure 4 works, and the carrying platform 41 can drive the plurality of groove pieces stacked in the up and down direction to move upward until the groove piece at the top moves to the feeding station, and then the top feeding structure 4 stops working and the carrying platform 41 stops moving, thereby ensuring the normal progress of the next loading work of the loading structure 3.

[0058] In addition, in the present utility model, the welding device 100 further includes a control device 5, and the control device 5 is electrically connected to the positioning structure 1, the rotating structure and the welding structure 2. When welding work needs to be carried out, the operator only needs to operate the control device 5. Since the control device 5 is electrically connected to the positioning structure 1, the rotating structure and the welding structure 2, the control device 5 can control the positioning structure 1, the rotating structure and the welding structure 2 to operate automatically, thereby completing the automatic welding work, so as to improve the welding efficiency and reduce the labor intensity of personnel at the same time.

[0059] It can be understood that the present utility model does not limit the specific structural form of the control device 5. For example, in an embodiment of the present utility model, the control device 5 can be configured as an operation panel; in another embodiment of the present utility model, the control device 5 can also be configured as a remote control terminal or other structures.

[0060] The above are only exemplary embodiments of the present utility model, and do not thus limit the patent scope of the present utility model. Any equivalent structural transformation made under the technical concept of the present utility model by using the content of the specification and drawings of the present utility model, or any direct / indirect application in other related technical fields is included within the patent protection scope of the present utility model.
