Description

Technical Field

[0001] This utility model relates to the field of stator processing equipment, and in particular to a stator spot welding test integrated machine. Background Technology

[0002] During the manufacturing process of a motor stator, the ends of the winding coils need to be welded to the lugs on the stator, and the stator needs to be tested after welding. Currently, many manufacturers use separate welding and testing equipment to perform these tasks separately, which is inefficient.

[0003] Meanwhile, existing welding equipment typically uses a positioning structure and a clamping structure to lock the stator in place. The stator is positioned and fitted onto the positioning structure, and then the clamping structure is driven to press the stator firmly onto the positioning structure. In this combination of positioning and clamping structures, gaps can easily exist between the stator and the positioning fitting, potentially leading to positioning deviations and low welding quality. Furthermore, the clamping structure requires a relatively long travel distance, resulting in higher costs.

[0004] Therefore, it is necessary to provide a stator spot welding test integrated machine to solve the above technical problems. Utility Model Content

[0028] Existing stator spot welding testing equipment suffers from low efficiency, low welding quality, and high cost.

[0029] The following is a preferred embodiment of a stator spot welding test integrated machine provided by this utility model, which can solve the above technical problems.

[0030] Please refer to Figure 1 and Figure 2 ,in Figure 1 This is a schematic diagram of a preferred embodiment of the stator spot welding test integrated machine of this utility model. Figure 2 This is a schematic diagram of the spot welding loading and unloading robot, the mold locking mechanism, and the spot welding mechanism in this utility model.

[0031] In the diagram, units with similar structures are represented by the same labels.

[0032] This embodiment provides a stator spot welding and testing integrated machine for spot welding and testing stators. The stator spot welding and testing integrated machine includes: a conveyor line 11, a spot welding loading and unloading robot 12, a mold clamping mechanism 13, a spot welding mechanism 14, a testing and clamping mechanism 15, and a testing mechanism 16. In this embodiment, the conveyor line 11 is a closed-loop annular conveyor line.

[0033] The clamping mechanism 13 and the testing mechanism 16 are arranged sequentially on one side of the conveyor line 11. The spot welding mechanism 14 is arranged above the clamping mechanism 13. The spot welding mechanism 14 is used to weld the stator clamped by the clamping mechanism 13. The testing and clamping mechanism 15 is arranged above the conveyor line 11. The testing mechanism 16 is used to test the stator clamped by the testing and clamping mechanism 15.

[0034] Please refer to Figure 2 , Figure 5 and Figure 6 The locking mechanism 13 in this embodiment includes: a fixed base 132, a rotating base 133, a telescopic rod 137, a rotation drive device 134, and a telescopic drive device 135.

[0035] The rotating seat 133 is rotatably mounted on the fixed seat 132. The rotating drive device 134 is fixedly mounted relative to the fixed seat 132. The rotating seat 133 is connected to the output end of the rotating drive device 134. The telescopic rod 137 is slidably mounted inside the rotating seat 133. The telescopic rod 137 is connected to the output end of the telescopic drive device 135.

[0036] Furthermore, one end of the rotating seat 133 is provided with a clamping end 1331, which includes multiple elastic clips distributed around the rotation axis of the rotating seat 133.

[0037] One end of the telescopic rod 137 is provided with a pressing end. The circumferential side of the pressing end is tapered. The tapered surface is movably fitted inside multiple elastic clamping pieces. As the telescopic rod 137 slides, the tapered surface can compress the multiple elastic clamping pieces to expand outward, thereby causing the multiple elastic clamping pieces to tighten inside the stator. When the multiple elastic clamping pieces are not compressed by the pressing end, they contract inward under the action of their own elastic force, so that the stator can be sleeved on the outer periphery of the clamping end 1331.

[0038] The elastic clip in this embodiment includes a locking plate 13311 and a connecting plate 13312. The connecting plate 13312 is connected between the locking plate 13311 and the rotating seat 133. The thickness of the locking plate 13311 is greater than the thickness of the connecting plate 13312. The locking plate 13311 has high strength and is not easily damaged. The connecting plate 13312 facilitates the elastic movement of the locking plate 13311 to make contact with the inner wall of the stator.

[0039] Please refer to Figure 2 In this embodiment, the spot welding loading and unloading robot 12 includes a fixed frame 121, a lifting frame 122, a lifting drive device 123, a rotating plate 124, a rotating drive device 125, and gripper parts 126. The lifting frame 122 is slidably connected to the fixed frame 121, the lifting drive device 123 is fixedly connected to the fixed frame 121, the lifting frame 122 is connected to the output end of the lifting drive device 123, the rotating drive device 125 is fixedly connected to the lifting frame 122, the rotating plate 124 is connected to the output end of the bottom of the rotating drive device 125, and the two gripper parts 126 are respectively connected to the two ends of the bottom of the rotating plate 124. This allows one gripper 126 to pick up the stator to be spot welded from the conveyor line 11 and transport it to the clamping mechanism 13, while the other gripper 126 can pick up the stator that has completed spot welding on the clamping mechanism 13 and transport it to the conveyor line 11. Then, the clamping mechanism 15 clamps the stator on the conveyor line 11, and the testing mechanism 16 tests the stator clamped by the testing mechanism 15. The overall operation is very efficient.

[0040] Please refer to Figures 2-4 In this embodiment, the stator spot welding test integrated machine also includes an electrode cleaning mechanism 17. Both the spot welding mechanism 14 and the electrode cleaning mechanism 17 are slidably arranged relative to the conveyor line 11. The electrode cleaning mechanism 17 includes a waste shielding box 171 and a cleaning wheel 172 disposed within the waste shielding box 171. A cleaning opening is provided on one side of the waste shielding box 171. The sliding trajectories of the electrode rod 141 of the spot welding mechanism 14 and the waste shielding box 171 intersect, allowing the electrode rod 141 of the spot welding mechanism 14 to move from the cleaning opening into the waste shielding box 171. This allows the cleaning wheel 172 to clean the electrode rod 141 of the spot welding mechanism 14, and the waste shielding box 171 prevents waste from splashing during the cleaning process. Cleaning the electrode rod 141 improves the spot welding quality.

[0041] In addition, a waste storage box can be provided below the sliding intersection of the electrode rod 141 and the waste shielding box 171, so that the waste that is brushed off the electrode rod 141 by the cleaning wheel 172 can fall into the waste storage box.

[0042] Please refer to Figure 1 In this embodiment, the stator spot welding and testing integrated machine also includes a cooling air bar 18 disposed on one side of the conveyor line 11. The cooling air bar 18 is located between the mold clamping mechanism 13 and the testing mechanism 16. The side of the cooling air bar 18 is provided with multiple air nozzles for blowing air onto the stator on the conveyor line 11. The cooling air bar 18 blows cold air onto the stator after spot welding, so that the spot weld of the stator can be quickly cooled and hardened, so that the subsequent testing mechanism 16 can test the stator, thereby improving work efficiency.

[0043] Please refer to Figure 1 In this embodiment, the stator spot welding test integrated machine also includes a defective product conveying platform 19 and a defective product conveying robot 1A. The defective product conveying platform 19 is located on the side of the testing mechanism 16 away from the mold-locking mechanism 13, and the defective product conveying robot 1A moves above the conveyor line 11 and the defective product conveying platform 19. Defective products detected by the test are picked up from the conveyor line 11 by the defective product conveying robot 1A and conveyed to the defective product conveying platform 19 for output.

[0044] Please refer to Figure 2 and Figure 6 In this embodiment, the mold-locking mechanism 13 further includes a mounting plate 1311, a belt drive assembly 139, and a transmission sleeve 138. A fixed base 132 is fixedly mounted on the top of the mounting plate 1311, a rotation drive device 134 is fixedly mounted on the bottom of the mounting plate 1311, and the transmission sleeve 138 is rotatably mounted within the fixed base 132. One end of the transmission sleeve 138 is connected to a rotating base 133, and the other end of the transmission sleeve 138 is connected to the output end of the rotation drive device 134 via the belt drive assembly 139.

[0045] A bearing can be installed between the inner walls of the transmission sleeve 138 and the fixed base 132 to facilitate the rotation of the transmission sleeve 138. The mounting plate 1311 is slidably connected to the base of the stator spot welding test integrated machine. The mounting plate 1311 can be driven to move by the motor lead screw assembly 136, and the nut block 1361 of the motor lead screw assembly 136 is fixedly connected to the mounting plate 1311. This allows for adjustment of the stator position on the clamping end for precise welding. It should also be noted that the stator's orientation can be determined by using a sensor.

[0046] Please refer to Figure 5The stator spot welding test machine includes a fixed ring 13A, located at one axial end of the rotating seat 133. A fastening screw 13A1 passes through the fixed ring 13A and is threaded into the rotating seat 133. The axial direction of the fastening screw 13A1 is parallel to the axial direction of the transmission sleeve 138. The fastening screw 13A1 passes through the rotating seat 133 and contacts the transmission sleeve 138, thereby improving the connection stability between the rotating seat 133 and the transmission sleeve 138. Furthermore, the support height for the stator can be changed by replacing the fixed ring 13A with one of different thicknesses.

[0047] Please refer to Figure 5 and Figure 6 In this embodiment, the telescopic rod 137 is slidably disposed within the transmission sleeve 138. The telescopic rod 137 includes a locking rod segment 1371 and a connecting rod segment 1372. One end of the locking rod segment 1371 is threadedly connected to one end of the connecting rod segment 1372. The extrusion end is located at the end of the locking rod segment 1371 away from the connecting rod segment 1372. The outer surface of the extrusion end is provided with a hexagonal countersunk groove so that the threaded connection between the locking rod segment 1371 and the connecting rod segment 1372 can be controlled by applying external force from the hexagonal countersunk groove.

[0048] The end of the connecting rod segment 1372 away from the locking rod segment 1371 is rotatably connected to the output end of the telescopic drive device 135. The rotation axis of the connecting rod segment 1372 is collinear with the central axis of the transmission sleeve 138. After the extrusion end and the clamping end 1331 are locked together, the telescopic rod 137 can rotate together with the rotating seat 133.

[0049] Please refer to Figure 5 and Figure 6 In this embodiment, a connecting hole is provided radially through the periphery of the transmission sleeve 138, and a first limiting elongated groove 1373 is provided radially through the connecting rod segment 1372. The extension direction of the first limiting elongated groove 1373 is consistent with the sliding extension direction of the connecting rod segment 1372. The limiting rod 13B passes through the connecting hole and the first limiting elongated groove 1373 to movably connect the transmission sleeve 138 and the connecting rod segment 1372.

[0050] Please refer to Figure 6 In this embodiment, the locking mechanism 13 further includes a fixing plate 1312 fixedly connected to the mounting plate 1311, and the telescopic drive device 135 is disposed on the fixing plate 1312.

[0051] The output end of the telescopic drive device 135 is rotatably connected to the connecting rod segment 1372 via an adapter rod 1351. A second limiting elongated groove is provided on the side of the adapter rod 1351, and the extension direction of the second limiting elongated groove is consistent with the sliding extension direction of the connecting rod segment 1372. An extension rod 13C is provided on the fixing plate 1312, and one end of the extension rod 13C is slidably engaged with the second limiting elongated groove. The extension rod 13C does not affect the extension and retraction of the adapter rod 1351, and at the same time, the extension rod 13C can restrict the rotation of the adapter rod 1351, preventing rotational wear at the connection between the adapter rod 1351 and the output end of the telescopic drive device 135.

[0052] The working principle of this utility model is as follows: Please refer to... Figure 1 In the view orientation, the stator to be processed is placed at the left end of the conveyor line 11 and transported on the inner side of the conveyor line 11. One gripper 126 of the spot welding loading and unloading robot 12 picks up the stator to be spot welded from the conveyor line 11 and transports it to the mold locking mechanism 13, while the other gripper 126 picks up the stator that has completed the spot welding work from the mold locking mechanism 13 and transports it to the conveyor line 11.

[0053] When the stator to be spot-welded is fitted onto the outer circumference of the clamping end 1331, the telescopic drive device 135 controls the telescopic rod 137 to retract downwards. The pressing end of one end of the telescopic rod 137 can press multiple elastic clamping pieces of the clamping end 1331 to expand outwards, thereby causing the multiple elastic clamping pieces to tighten on the inner side of the stator. Then, the rotation drive device 134 controls the rotating seat 133 to rotate according to a preset program through the transmission sleeve 138, and the spot welding mechanism 14 can perform spot welding operations on multiple spot welding positions on the circumference of the stator. After the spot welding work is completed, the telescopic drive device 135 controls the telescopic rod 137 to extend upwards, and the pressing end no longer presses the multiple elastic clamping pieces. The multiple elastic clamping pieces contract inwards under the action of their own elastic force, so that the stator can be picked up by the spot welding loading and unloading robot 12 and transported back to the conveyor line 11.

[0054] Then, the conveyor line 11 conveys the stator to the underside of the clamping mechanism 15, the clamping mechanism 15 clamps the stator on the conveyor line 11, the testing mechanism 16 moves to test the stator clamped by the clamping mechanism 15 and then performs the test operation.

[0055] Finally, defective products detected are picked up from conveyor line 11 by defective product conveying robot 1A and transported to defective product conveying platform 19 for output. Stators that pass inspection are transported to the outer side of conveyor line 11 for easy removal of processed stators.

[0056] This completes the spot welding and testing process of the stator spot welding and testing integrated machine in this embodiment.

[0057] This preferred embodiment of the stator spot welding and testing integrated machine can perform spot welding and testing work in a continuous and efficient manner. Furthermore, the clamping mechanism controls the opening of the clamping end by extending and retracting the telescopic rod, thereby allowing the clamping end to tighten tightly inside the stator, forming a stable and precise positioning and locking of the stator, thus improving welding quality. At the same time, the extension and retraction stroke of the telescopic rod needs to be kept short, resulting in low overall cost.

[0058] In summary, although the present invention has been disclosed above with reference to preferred embodiments, the above preferred embodiments are not intended to limit the present invention. Those skilled in the art can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope defined in the claims.
