Description

Technical Field

[0001] The utility model relates to the technical field of motor stators, in particular to a flux coating device and welding equipment. Background Art

[0002] The stator is the stationary part of the motor or generator. The stator consists of three parts: the stator core, the stator winding and the base. During the motor production process, the pins arranged circumferentially at one end of the stator core need to be soldered to the PCB (Printed Circuit Board), so that the stator core winding can be connected to other circuits. In order to ensure the quality of the soldering connection, flux needs to be applied in advance to the welding point between the stator core and the PCB board before soldering to avoid poor soldering such as leaking solder and cold soldering.

[0003] Currently, the stator core to be welded is usually placed on a workbench with the PCB board of the stator core facing upward, and then the stator core is grasped by a robot or a gripper and placed in a position for applying flux, and then the flux is dipped into a sponge, a brush or the like and directly applied to the pins.

[0004] Since the PCB to be soldered is located at the top of the stator core, during the process of applying the flux, the excess flux is likely to flow onto the stator core, which not only wastes the flux but also contaminates the stator core; if the stator core is turned over and the PCB is placed at the bottom of the stator core, the PCB to be soldered is very likely to fall off. Therefore, the above problems need to be solved urgently. Utility Model Content

[0049] The present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the present invention, rather than to limit the present invention. It should also be noted that, for ease of description, only the parts related to the present invention, rather than all structures, are shown in the accompanying drawings.

[0052] In the description of this embodiment, the terms "upper", "lower", "right", etc., are based on the directions or positions shown in the drawings, and are only for the convenience of description and simplified operation, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation of the present invention. In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

[0053] Refer to the following Figures 1 to 8 The flux coating device and welding equipment provided by the present invention are described.

[0054] Reference Figure 1 and Figure 2 The flux coating device includes a coating transfer mechanism 11, a coating clamping mechanism 12, a coating rotating mechanism 13 and a coating mechanism 14. The coating clamping mechanism 12 is connected to the coating transfer mechanism 11, and the coating transfer mechanism 11 and the coating rotating mechanism 13 are arranged opposite to each other.

[0055] Optionally, the coating and transplanting mechanism 11 is any mechanism in the prior art that can transplant the stator core 100, such as a two-axis moving mechanism, a three-axis moving mechanism, a three-axis manipulator, etc. This embodiment takes a two-axis moving mechanism as an example.

[0056] Reference Figure 2 and Figure 3 Specifically, the coating clamping mechanism 12 includes a stator clamping member 121, a gland clamping member 122 and a positioning assembly 124. The gland clamping member 122 is located on the side of the stator clamping member 121 close to the coating rotating mechanism 13. The stator clamping member 121 and the gland clamping member 122 are both components capable of clamping cylindrical materials in the prior art, such as a manipulator, a pneumatic clamp, etc., and the present embodiment takes a pneumatic clamp as an example.

[0057] Reference Figure 1 , Figure 2 and Figure 4Further, the positioning assembly 124 includes a positioning plate 1241, a positioning head 1242, an elastic connector 1243 and a guide rod 1244. The positioning plate 1241 is horizontally arranged, and one side of the positioning plate 1241 is connected to the top of the stator clamp 121. The positioning head 1242 is located below the positioning plate 1241. The positioning head 1242 is cylindrically arranged. The diameter of the positioning head 1242 is larger than the inner diameter of the stator core 100, and the bottom of the positioning head 1242 is spherical. The elastic connector 1243 is connected between the positioning plate 1241 and the positioning head 1242. Optionally, the elastic connector 1243 is an elastic connector in the prior art, such as a spring, an air bag, a rubber column and other components. The spring is taken as an example in this embodiment.

[0058] Based on the above, before the stator clamping member 121 clamps the stator core 100, the coating and transplanting mechanism 11 drives the stator clamping member 121 to move to the top of the stator core 100, and then the coating and transplanting mechanism 11 drives the stator clamping member 121 downward in the vertical direction. In this process, the positioning head 1242 first abuts against the PCB board 200 on the stator core 100, and applies elastic force to the PCB board 200 through the spring, so that the PCB board 200 abuts against the stator core 100, and then the stator core 100 is clamped by the stator clamping member 121. Finally, it is ensured that the stator core 100 is not easy to rotate around its own axis during the process of clamping the stator core 100, and the error during the operation process is reduced, thereby ensuring that the U, V, and W terminals on the PCB board 200 are accurately positioned, which is convenient for the subsequent process of installing the stator core 100 into the motor housing, and the U, V, and W terminals on the PCB board 200 are aligned with the reserved holes on the motor housing.

[0059] Furthermore, the guide rod 1244 is vertically arranged, that is, the axis of the guide rod 1244 is parallel to the stator core 100 to be clamped by the stator clamp 121, the guide rod 1244 slides through the positioning plate 1241, the top of the guide rod 1244 is connected to the limiting head 1245, the limiting head 1245 is placed on the top of the positioning plate 1241, the spring is sleeved on the outside of the guide rod 1244, and the spring abuts between the positioning plate 1241 and the positioning head 1242.

[0060] When the spring is in a natural state, the spring applies a downward elastic force to the positioning head 1242, so that the limiting head 1245 is pressed against the positioning plate 1241. When the positioning head 1242 abuts against the stator core 100 and moves upward, the movement of the positioning head 1242 is guided and limited by the guide rod 1244 to prevent the positioning head 1242 from moving away.

[0061] Reference Figure 3 and Figure 5, the gland clamping member 122 can clamp the gland 123, the gland 123 is pre-placed between the coating transplanting mechanism 11 and the coating rotating mechanism 13, the gland 123 can abut against the PCB board 200, and is positioned on the stator core 100. Specifically, the gland 123 includes a first plate portion 1231, a plug-in ring 1232 and a material taking head 1233, the first plate portion 1231 is horizontally arranged, the plug-in ring 1232 is connected to the bottom of the first plate portion 1231, the plug-in ring 1232 can be plugged into the inner ring of the stator core 100, that is, the outer diameter of the plug-in ring 1232 is smaller than the inner diameter of the stator core 100, and the material taking head 1233 is connected to the top of the first plate portion 1231.

[0062] Furthermore, the plug-in ring 1232 can abut against the inner ring of the stator core 100, and / or the plug-in ring 1232 can magnetically absorb the stator core 100. Specifically, the outer wall of the plug-in ring 1232 is abutted against the inner ring of the stator core 100, so that the plug-in ring 1232 and the inner ring of the stator core 100 maintain a certain friction force, thereby pressing the PCB board 200 on the stator core 100, and when the stator core 100 is inverted, the PCB board 200 is not easy to separate from the stator core 100. The plug-in ring 1232 is made of a magnet or a magnet is fixed on the plug-in ring 1232, so that after the plug-in ring 1232 is plugged into the inner ring of the stator core 100, the gland 123 can magnetically absorb the stator core 100, and the gland 123 can also play the effect of positioning the gland 123. In this embodiment, the outer wall of the plug-in ring 1232 is abutted against the inner ring of the stator core 100, and the plug-in ring 1232 is made of magnets, thereby ensuring that the pressure cover 123 works stably.

[0063] Reference Figure 6 The coating rotating mechanism 13 includes a lifting component 131, a first rotating driving member 132, a second rotating driving member 133 and a rotating clamp 134. The lifting component 131 is a component in the prior art that can drive components to lift, such as a screw lifting component 131, and the specific structure is not limited.

[0064] Furthermore, the first rotating driving member 132 is connected to the lifting assembly 131, and the rotation axis of the first rotating driving member 132 is horizontally arranged. The second rotating driving member 133 is connected to the first rotating driving member 132, and the rotation axis of the second rotating driving member 133 is perpendicular to the rotation axis of the first rotating driving member 132. The first rotating driving member 132 and the second rotating driving member 133 are both components that can drive components to rotate in the prior art, such as a rotating cylinder, a motor, etc. This embodiment is described by taking a rotating cylinder as an example. The rotating jaw 134 is connected to the second rotating driving member 133, and the structure of the rotating jaw 134 is similar to that of the stator clamp 121, which will not be repeated here.

[0065] Based on the above, before applying the flux, the stator core 100 is first transferred to the rotating clamp 134 by the coating and transfer mechanism 11, and the stator core 100 is clamped by the rotating clamp 134, and then the pressure cover 123 is placed on the stator core 100 by the coating and transfer mechanism 11, and the PCB board 200 is pressed on the stator core 100 by the pressure cover 123, and then the first rotating driving member 132 drives the stator core 100 to flip, so that the stator core 100 is tilted, and the position of the stator core 100 to be coated with flux is located at the lowest point of the stator core 100. Since the PCB board 200 is pressed by the pressure cover 123, after the stator core 100 is flipped and inverted, the PCB board 200 is not easy to fall. Then the stator core 100 is driven to rotate around its axis direction by the second rotating driving member 133.

[0066] Reference Figure 6 and Figure 7 The coating mechanism 14 includes a solvent placement groove 141, a coating seat 142, a connecting bracket 144 and a flexible coating member 143. Liquid soldering flux is stored in the solvent placement groove 141. The coating seat 142 is located on one side of the solvent placement groove 141. The connecting bracket 144 is slidably connected to the coating seat 142. The connecting bracket 144 slides in a vertical direction. The sliding of the connecting bracket 144 is driven by a cylinder.

[0067] Furthermore, the flexible coating member 143 is connected to the connecting bracket 144 . The flexible coating member 143 is located above the agent placement groove 141 . The flexible coating member 143 may be a sponge, a brush or the like. In this embodiment, a brush is taken as an example, and the handle of the brush is connected to the connecting bracket 144 .

[0068] Based on the above, when the coating mechanism 14 is working, the connecting bracket 144 drives the brush to descend, so that the brush dips into the solder flux inside the solvent placement groove 141, and then the connecting bracket 144 drives the brush to rise, so that the bristles of the brush contact the position on the stator core 100 to be coated with solder flux, and at this time, the second rotating driving member 133 drives the stator core 100 to rotate around its axis direction, so that the solder flux is evenly coated on the stator core 100 throughout the whole circumference. The connecting bracket 144 can also be rotatably connected to the coating seat 142, and it is only necessary to make the rotated brush contact the position on the stator core 100 to be coated with solder flux.

[0069] It should be added that the second rotary drive member 133 in the coating rotary mechanism 13 may be omitted, and only a liftable annular brush is required to coat the flux around the entire circumference of the stator core 100.

[0070] Reference Figure 1 and Figure 8The welding equipment includes a workbench 5, a conveying device 2, a flux coating device, a welding device 3 and a detection device 4. The conveying device 2, the flux coating device, the welding device 3 and the detection device 4 are all arranged on the workbench 5. The conveying device 2 conveys the stator core 100 along a preset direction. The flux coating device, the welding device 3 and the detection device 4 are sequentially distributed on one side of the conveying device 2 along the conveying direction of the conveying device 2.

[0071] In this embodiment, the stator core 100 needs to be placed on a carrier for transportation. The conveying device 2 is any linear conveying mechanism in the prior art, such as a belt conveying mechanism, a chain conveying mechanism, a roller conveying mechanism, etc. This embodiment takes a belt conveying mechanism as an example.

[0072] The specific structure of the flux coating device is described in the above embodiment, which will not be described here. The welding device 3 includes a welding transfer mechanism 31, a welding rotation mechanism 33 and a tin liquid pool 34. A cache position 51 is provided on the workbench 5. The cache position 51 is located between the welding transfer mechanism 31 and the welding rotation mechanism 33 and is arranged close to the conveying device 2.

[0073] Furthermore, the structure of the welding transfer mechanism 31 is consistent with that of the coating transfer mechanism 11. The welding clamping mechanism 32 is connected to the welding transfer mechanism 31. The structure of the welding clamping mechanism 32 is similar to that of the coating clamping mechanism 12. The difference is that the welding clamping mechanism 32 has an additional cache clamping claw compared to the coating clamping mechanism 12. The stator core 100 on the carrier can be removed first and placed on the cache position 51, so that the conveying device 2 can continue to convey the carrier forward, thereby improving the efficiency of the carrier cycle. In addition, the cover plate in the welding transfer mechanism 31 is made of a non-stick tin material, such as a titanium alloy, to ensure that the surface of the cover plate is clean.

[0074] Based on the above, when the welding rotating mechanism 33 is working, it directly drives the stator core 100 to flip, so that the stator core 100 is tilted, and the position to be welded on the stator core 100 is located at the lowest point of the stator core 100. The stator core 100 is then driven down by the welding rotating mechanism 33, so that the position to be welded on the stator core 100 is immersed in the tin liquid. At the same time, the stator core 100 rotates around its axis direction, so that the stator core 100 is evenly coated with the tin liquid throughout the whole circle, thereby completing the welding of the stator core 100 and the PCB board 200.

[0075] Reference Figure 2 and Figure 8The detection device 4 includes a detection transplanting mechanism 41, a detection clamping mechanism 42, a detection positioning seat 43 and a detection member 44. The structure of the detection transplanting mechanism 41 is consistent with the structure of the coating transplanting mechanism 11. The detection clamping mechanism 42 is connected to the detection transplanting mechanism 41. The structure of the detection clamping mechanism 42 is similar to that of the coating clamping mechanism 12. The difference is that the pressure cover clamping member 122 is not provided in the detection clamping mechanism 42. The detection member 44 is connected to the detection transplanting mechanism 41. The detection member 44 is any detection member 44 in the prior art that can check the welding quality, such as a welding detection camera, a CDD detection camera, etc. This embodiment is described by taking a welding detection camera as an example, and the lens of the welding detection camera is set downward.

[0076] Furthermore, the detection positioning seat 43 is arranged on the workbench 5, and the detection positioning seat 43 is provided with a rotating drive member and a clamp, the clamp can clamp the stator core 100, the rotating drive member can drive the stator core 100 to rotate around its own axis direction, and the rotating drive member is a rotating cylinder.

[0077] Based on the above, the stator core 100 is transferred to the detection positioning seat 43 by the detection transfer mechanism 41, and then the stator core 100 is inspected by the welding detection camera. In addition, in order to improve the detection effect, an auxiliary detection component 45 is additionally provided on the workbench 5, and the auxiliary detection component 45 is a welding detection camera, and the lens of the welding detection camera faces the side of the stator core 100, so as to perform a full range of detection of the welding quality of the stator core 100.

[0078] Furthermore, a conveyor belt 52 is provided on the workbench 5, and the conveyor belt 52 is located at a position where the detection and transplanting mechanism 41 is far away from the conveying device 2. When a stator core 100 with unqualified welding is detected, the stator core 100 is transplanted to the conveyor belt 52 through the detection and transplanting mechanism 41, so as to facilitate unified processing of the unqualified stator cores 100.

[0079] The working process of the welding equipment of the present utility model is as follows: the carrier equipped with the stator core 100 is transported by the conveying device 2. When the carrier reaches one side of the coating and transplanting mechanism 11, the coating and transplanting mechanism 11 drives the stator clamping member 121 to move above the stator core 100, and first uses the positioning component 124 to press the PCB board 200, and then the stator clamping member 121 grabs the stator core 100 and transplants the stator core 100 to the rotating clamping claw 134. At this time, the coating and transplanting mechanism 11 drives the pressure cover clamping member 122 to move above the stator core 100, and the pressure cover 123 is covered on the stator core 100, and the PCB board 200 is pressed on the stator core 100 by the pressure cover 123.

[0080] Then the first rotating driving member 132 drives the stator core 100 to flip, so that the stator core 100 is tilted, and the position on the stator core 100 to be coated with flux is located at the lowest point of the stator core 100, and then the second rotating driving member 133 drives the stator core 100 to rotate around its axis direction, and the stator core 100 rotates while contacting the position on the stator core 100 to be coated with flux through the brush, so that the stator core 100 is evenly coated with flux throughout the whole circumference. After the coating is completed, the coating and transplanting mechanism 11 transplants the stator core 100 to the carrier of the conveying device 2 and continues to transport it forward.

[0081] When the carrier with the stator core 100 reaches one side of the welding device 3, the welding device 3 welds the stator core 100 in accordance with the above-mentioned process of applying the flux, except that the stator core 100 is directly immersed in the tin liquid during welding. After welding is completed, the welding transfer mechanism 31 transfers the stator core 100 to the carrier of the conveying device 2 and continues to transport it forward.
