[0003] The existing motor flat wire busbar is assembled by a busbar welding machine. The insulating base is fixed on a welding table, and then the positioner is installed and the position between the positioner and the pins of the insulating base is adjusted. After the adjustment is completed, the connection row is inserted into the positioner and fixed. The pins of the insulating base are in contact with the bottom of the connection row, and then the in contacting part is welded by a welding gun to form a motor flat wire busbar.

[0004] The existing busbar welding machine still has some problems in actual use. During the docking process of the bottom of the connecting bar and the pin of the insulating base, the staff first places the insulating base on the welding table, and then places the connecting bar on the positioner and fixes it. Then, the positioner is put on the welding table, and the position of the connecting bar on the positioner is adjusted by rotating the positioner so that the bottom of the connecting bar on the positioner contacts the pin of the insulating base. However, in actual operation, this docking operation is relatively complicated and takes a long time, which reduces the production efficiency of the motor flat wire bus. At the same time, errors are prone to occur during the docking process, and the quality of each motor flat wire bus produced cannot be ensured, which reduces the product yield.

[0041] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0042] Embodiment 1

[0043] like Figures 1 to 13 As shown, a motor flat wire busbar according to an embodiment of the present invention comprises a workstation 1, a welding device is arranged in the workstation 1, the welding device comprises an electric guide rail 11, the electric guide rail 11 is fixed on an inner wall of one side of the workstation 1, a sliding block 12 is slidably connected to the electric guide rail 11, a telescopic steering device 13 is fixedly arranged on one side of the sliding block 12, a welder 14 is fixedly arranged at the output end of the telescopic steering device 13, the welder 14 is composed of a mechanical arm and a welding gun, the welding gun is fixed on the mechanical arm, a welding platform 15 is fixedly arranged at the bottom of the workstation 1, an outer ring block 16 is fixedly connected to the surface of the welding platform 15, and the welding devices are symmetrically arranged on both sides of the inside of the workstation 1;

[0044] A quick positioning assembly is provided on the welding platform 15, and the quick positioning assembly is composed of a clamping component and a positioning component. The clamping component includes a rotating block 22, a wedge-shaped slider 26 is slidably provided in the rotating block 22, and a plurality of clamping blocks 223 are slidably provided on the top of the rotating block 22. When the insulating base is placed in the middle of the top of the rotating block 22, the wedge-shaped slider 26 is pressed down, so that the plurality of clamping blocks 223 are contracted toward the middle of the rotating block 22, thereby clamping the bottom of the insulating base;

[0045] The positioning component includes a blocking block 227, one side of which is fixedly connected to a contact 230, and a blocking block 228 is fixedly connected to the top of the welding platform 15, and one side of the blocking block 228 is fixedly connected to a contact 231. When the rotating block 22 rotates, the outermost pin of the insulating base contacts with the blocking block 227 and drives the blocking block 227 to rotate until the contact 230 contacts with the contact 231, so that the rotating block 22 stops rotating. At this time, the insulating base completes the positioning;

[0046] A fastening assembly is fixedly arranged on the outer ring block 16, and the fastening assembly includes a fixed plate 32, a sliding block 34 is slidably arranged inside the fixed plate 32, a limiter 35 is fixedly arranged at one end of the sliding block 34, a transmission gear 38 is fixedly connected to the top of the fixed plate 32, and a transmission rack block 310 is fixedly arranged on the top of the limiter 35. The transmission rack block 310 drives the limiter 35 to contract through the counterclockwise rotation of the transmission gear 38, so that the bottom end of the connection row fixed on the limiter 35 and the pin of the insulating base are more tightly contacted.

[0047] Specifically, the existing busbar welding machine still has some problems in actual use. When placing the insulating base, it is necessary to adjust the position of the pins of the insulating base after placement, and then adjust the position of the limiter 35, so that the bottom of the connecting row on the limiter 35 finally conflicts with the pins of the insulating base. This operation is relatively complicated and takes a long time, which reduces the production efficiency of the motor flat wire busbar.

[0048] Therefore, the present invention solves this problem by setting a corresponding structure. First, the connection row is inserted into the sliding block 2 34, and the connection row is fixed by the sliding block 2 34. Then, when the insulating base is placed in the middle of the top of the rotating block 22, the wedge-shaped slider 26 is pressed down to make the multiple clamping blocks 223 shrink toward the middle of the rotating block 22, thereby clamping the bottom of the insulating base. Then, the rotating block 22 is rotated. Through the rotation of the rotating block 22, the outermost pins of the insulating base are in conflict with the blocking block 1 227 and drive the blocking block 1 227 to rotate. , until the contact 1 230 and the contact 2 231 collide, so that the rotating block 22 stops rotating. At this time, the bottom of the connecting row and the pin of the insulating base collide. Because the connecting row and the insulating base need to leave a partial gap during the docking process to prevent the pin of the insulating base from scratching the bottom surface of the connecting row during the rotation of the rotating block 22, after the docking is completed, the transmission rack block 310 drives the limiter 35 to contract by the counterclockwise rotation of the transmission gear 38, so that the bottom end of the connecting row fixed on the limiter 35 and the pin of the insulating base are more tightly in contact;

[0049] At this time, the two electric guide rails 11 are started, and the welding gun nozzles on the two welders 14 are relatively moved through the displacement of the sliding block 12 and the telescopic steering of the telescopic steering device 13, so that the bottom of the connecting row and the pins of the insulating base are clamped by the two welding gun nozzles, and then welding is performed. The above operation is repeated many times, thereby completing the welding between the connecting row and the insulating base;

[0050] Then the quick clamping assembly is reset, the formed motor flat wire busbar is taken out, and the above operation is repeated to produce the next motor flat wire busbar.

[0051] Embodiment 2

[0052] like Figures 2 to 13 As shown, compared with Example 1, another implementation of the present invention is:

[0053] like Figures 3 to 7As shown, the clamping component of this embodiment also includes a motor 21, which is fixed inside the welding platform 15. A rotating groove 23 is provided on the top of the rotating block 22, and a rack circular plate 211 is rotatably connected in the rotating groove 23. A contraction groove 24 is provided on the top of the rotating block 22, and a clamping groove 25 is provided on the top of the rotating block 22. The rotating groove 23 is connected to the contraction groove 24, and the contraction groove 24 is connected to the clamping groove 25. The wedge-shaped slider 26 slides inside the contraction groove 24, and the top of the wedge-shaped slider 26 is connected to the contraction groove 24. A return spring 28 is fixedly connected between the tops of the rotating blocks 22, a wedge-shaped rack block 29 is slidably connected in the contraction groove 24, the wedge shape at the bottom of the wedge-shaped slider 26 matches the wedge shape on one side of the wedge-shaped rack block 29, a compression spring 210 is fixedly connected between one end of the wedge-shaped rack block 29 and an inner wall of one side of the contraction groove 24, a guide gear 27 is rotatably connected in the wedge-shaped rack block 29, one side of the guide gear 27 is meshed with the rack circular plate 211, and the other side is meshed with the clamping groove 25.

[0054] Specifically, initially, the wedge-shaped slider 26 is not deformed, the compression spring 210 is not deformed, and the guide gear 1 27 is located at one end of the wedge-shaped rack block 29 close to the compression spring 210;

[0055] When the insulating base is placed in the middle of the top of the rotating block 22, the wedge-shaped slider 26 is pressed downward to elastically compress the return spring 28, and the downwardly moving wedge-shaped slider 26 pushes the wedge-shaped rack block 29 to slide and elastically compresses the compression spring 210. At the same time, the sliding wedge-shaped rack block 29 drives the rack circular plate 211 to rotate through the guide gear 27;

[0056] After clamping the insulating base, the motor 1 21 is started, and since the output shaft of the motor 1 21 is fixed to one end of the rotating block 22, the rotating block 22 is rotated.

[0057] like Figures 6 to 9 As shown, in this embodiment, a fixing rod 212 is fixedly connected to the bottom of the clamping groove 25, a rack slider 213 is slidably connected to the bottom of the fixing rod 212, a resisting block 1 214 is fixedly connected to the top of the fixing rod 212, and a resisting block 215 is slidably connected to the surface of the fixing rod 212, and the resisting block 215 is located between the resisting block 1 214 and the rack slider 213;

[0058] A limit groove 216 is provided at the bottom of the wedge-shaped slider 26, and a second contraction groove 217 is symmetrically arranged inside the limit groove 216. The second contraction groove 217 consists of a cylindrical groove and a rectangular groove, and the cylindrical groove is connected to the rectangular groove. A locking block 218 is slidably arranged in each contraction groove 217. The locking block 218 consists of a circular plate, a round rod and a wedge-shaped abutment block. The circular plate slides in the cylindrical groove, the round rod slides in the rectangular groove and the cylindrical groove, and the wedge-shaped abutment block slides in the rectangular groove. A return spring 219 is fixedly connected between one side of the block 218 and the inner wall of the rectangular groove. The wedge-shaped slider 26 slides in the clamping groove 25. When the wedge-shaped slider 26 slides into the clamping groove 25, the two locking blocks 218 are used to make the locking block 218 located between the resistance block 1 214 and the resistance block 2 215. Under the elastic stretching action of the return spring 1 28, the wedge-shaped slider 26 remains stationary, and the shape of the resistance block 1 214 matches the shape of the resistance block 2 215.

[0059] Specifically, after the wedge-shaped slider 26 contacts the wedge-shaped rack block 29, the wedge-shaped slider 26 continues to move downward, and the wedge-shaped slider 26 slides into the engaging groove 25. During this process, the hypotenuse of the locking block 218 contacts the contact block 1 214, causing the locking block 218 to shrink into the rectangular groove and elastically compress the return spring 219 until the wedge-shaped slider 26 is pressed to the maximum distance. At this time, the locking block 218 is located between the contact block 215 and the contact block 1 214. The locking block 218 is reset under the elastic release of the return spring 219. At this time, the wedge-shaped slider 26 is no longer pressed. Under the elastic stretching of the return spring 1 28, the wedge-shaped slider 26 will move upward. At this time, the top of the locking block 218 contacts the bottom of the contact block 1 214, so that the wedge-shaped slider 26 is limited, and the return spring 1 28 continues to be in an elastically compressed state.

[0060] When the second contact block 215 moves upward, the second contact block 215 squeezes the locking block 218, causing the locking block 218 to shrink and elastically compress the second return spring 219 until the top of the locking block 218 contacts the bottom of the second contact block 215. At this time, the locking block 218 no longer contacts the bottom of the first contact block 214. Under the elastic stretching of the return spring 1 28, the wedge-shaped slider 26 is reset. During this process, the locking block 218 is reset.

[0061] like Figure 5 and Figure 7 As shown, in this embodiment, a plurality of guide grooves 1 220 are provided on the top of the rotating block 22, and a plurality of guide grooves 221 are provided on the rack circular plate 211. The guide grooves 221 correspond to the guide grooves 1 220 one by one. A guide rod 222 is slidably connected between each group of guide grooves 1 220 and guide grooves 2 221. Each clamping block 223 is fixed on the top of the corresponding guide rod 222. When the rack circular plate 211 rotates, the plurality of clamping blocks 223 shrink toward the middle of the rotating block 22, thereby clamping the bottom of the insulating base.

[0062] Specifically, the guide groove 1 220 is set as a straight groove, and the guide groove 221 is set as an oblique groove. In the initial state, the guide rod 222 is located at one end close to the side of the rack circular plate 211;

[0063] During the rotation of the rack circular plate 211, since the guide groove 1 220 is provided on the rotating block 22 and the guide groove 221 is provided on the rack circular plate 211, the rack circular plate 211 rotates inside the rotating block 22, so that the guide rod 222 is limited and does not fall over. Through the rotation of the rack circular plate 211, the guide rod 222 drives the clamping block 223 to move toward the direction close to the middle of the rotating block 22, and then the insulating base is clamped and fixed through the synchronous movement of multiple clamping blocks 223.

[0064] like Figures 6 to 9 As shown, in this embodiment, a trigger rack block 224 is slidably connected to the top of the wedge-shaped slider 26, and the trigger rack block 224 slides through the top of the rotating block 22. The bottom of the trigger rack block 224 slides in the clamping groove 25. A limit spring 225 is fixedly connected between the top of the trigger rack block 224 and the top of the rotating block 22. A gear rod 226 is rotatably connected in the clamping groove 25. One side of the gear rod 226 is meshed with the rack slider 213, and the other side is meshed with the bottom of the trigger rack block 224.

[0065] Specifically, when the wedge-shaped slider 26 is pressed down, the trigger rack block 224 moves synchronously with the wedge-shaped slider 26. At this time, the trigger rack block 224 is located in the clamping groove 25. After welding is completed, the trigger rack block 224 is pressed downward. During the pressing process of the trigger rack block 224, the limit spring 225 will be elastically compressed. At the same time, the bottom of the trigger rack block 224 will engage with the gear rod 226, causing the gear rod 226 to rotate. The rotation of the gear rod 226 drives the rack slider 213 to slide upward, causing the interference block 215 to move upward until the top of the interference block 215 conflicts with the bottom of the interference block 1 214. At this time, the trigger rack block 224 is pressed to the farthest distance.

[0066] like Figure 3 , Fig.10 and Fig.11 As shown, the positioning assembly of this embodiment also includes a reset spring three 229, which is fixed between the blocking block two 228 and the blocking block one 227. The blocking block one 227 is composed of a rotating shaft rod and a baffle. The top of the rotating shaft rod is fixed to one end of the baffle. The contact one 230 is arranged on one side of the baffle, and the contact two 231 is located on the movement trajectory of the contact one 230.

[0067] Specifically, initially, the baffle constituting the blocking block 227 is located on the motion track of the outermost pin of the insulating base;

[0068] When the motor 1 21 is started and the rotating block 22 is rotated, the insulating base clamped by the multiple clamps 223 rotates synchronously until the outermost pins of the insulating base collide with the baffle, causing the baffle to be synchronously displaced through the rotating shaft rod until the contact 1 230 and the contact 2 231 collide, causing the motor 1 21 to stop moving, thereby completing the positioning between the insulating base and the connecting row. During this process, the reset spring 3 229 is elastically compressed to provide a buffer for the conflict between the contact 1 230 and the contact 2 231.

[0069] The present invention presses down the wedge-shaped slider 26 to make the multiple clamping blocks 223 clamp the insulating base, and limits the two locking blocks 218 by the abutment block 1 214, so that the wedge-shaped slider 26 remains stationary, so that the clamping blocks 223 always stably clamp the insulating base plate; at the same time, by rotating the rotating block 22, the outermost pins of the insulating base plate abut against the baffle constituting the blocking block 1 227, so that the contact 1 230 abuts against the contact 2 231, so that the rotating block 22 stops rotating. At this time, the pins of the insulating base plate are located at the connection on the sliding block 2 34. The bottom of the row is located below the insulating base plate, thereby completing the positioning between the insulating base and the connecting row, and there is no need to manually adjust the position of the insulating base and the connecting row. This operation is simple and convenient. Compared with the prior art, the positioning speed is fast, and the production efficiency of the motor flat wire bus is improved; in addition, by pressing the trigger rack block 224 to make the resistance block 215 move upward, the wedge-shaped slider 26 is no longer limited, and the wedge-shaped slider 26 is reset. At the same time, the clamping block 223 no longer clamps the welded motor flat wire bus, which is convenient for the staff to take out.

[0070] like Figures 2 to 4 , Fig.10 , Figures 11 to 13 As shown, the fastening assembly of this embodiment also includes a support rod 31, which is fixed on the top of the outer ring block 16. A sliding groove 33 is provided on one side of the fixed plate 32. The sliding block 34 slides in the sliding groove 33. The top of the fixed plate 32 is fixedly connected to a support plate 36, and the top of the support plate 36 is fixedly connected to a motor 37. The transmission gear 38 and the motor 37 are on the same axis. The top of the fixed plate 32 is fixedly connected to a guide gear 39, which meshes with the transmission rack block 310, and the transmission rack block 310 slides on the top of the fixed plate 32.

[0071] Specifically, the transmission gear 38 has a small number of teeth and the teeth are symmetrically arranged. When the contact 1 230 and the contact 2 231 collide with each other, the motor 2 37 is started at this time, and the transmission gear 38 is driven to rotate counterclockwise through the output end of the motor 2 37. The rotation of the transmission gear 38 drives the transmission rack block 310 to move, so that the sliding block 2 34 slides into the sliding groove 33, and at the same time drives the limiter 35 to move synchronously, so that the bottom end of the connection row fixed on the limiter 35 and the pin of the insulating base are more closely contacted, so that the joint after welding forms a sealed and solid connection, which improves the overall mechanical strength while preventing moisture, dust and other pollutants from entering the connection, thereby improving the service life of the motor flat wire bus;

[0072] In addition, after welding and removing the motor flat wire busbar, the second motor 37 is started again, and the transmission gear 38 is meshed with the second guide gear 39, so that the second guide gear 39 drives the transmission rack block 310 to move in the reverse direction to reset it.

[0073] like Fig.10 As shown, one side of the blocking block 228 of this embodiment is parallel to one side of the limiter 35, and the blocking block 1 227 is arranged below the fixed plate 32. When the contact 1 230 conflicts with the contact 2 231, the bottom of the connection row on the sliding block 2 34 conflicts with the pin of the insulating base.

[0074] Specifically, when the first contact 230 contacts the second contact 231 , the bottom of the connection row on the second sliding block 34 and the pins of the insulating base are in the same straight line.

[0075] Working principle:

[0076] First, the connection row is inserted into the sliding block 2 34, and the connection row is fixed by the sliding block 2 34. Then, when the insulating base is placed in the middle of the top of the rotating block 22, the wedge-shaped slider 26 is pressed down to elastically compress the reset spring 1 28. The downwardly moving wedge-shaped slider 26 pushes the wedge-shaped rack block 29 to slide and elastically compresses the compression spring 210. At the same time, the sliding wedge-shaped rack block 29 drives the rack circular plate 211 to rotate through the guide gear 1 27, so that the guide rod 222 drives the clamping block 223 to move toward the direction close to the middle of the rotating block 22, and then the insulating base is clamped and fixed by the synchronous movement of multiple clamping blocks 223.

[0077] As the wedge-shaped slider 26 continues to be pressed downward, the wedge-shaped slider 26 slides into the engaging groove 25. During this process, the hypotenuse of the locking block 218 and the abutment block 1 214 abut each other, causing the locking block 218 to shrink into the rectangular groove and elastically compress the return spring 219 until the wedge-shaped slider 26 is pressed to the maximum distance. At this time, the locking block 218 is located between the abutment block 215 and the abutment block 1 214. The locking block 218 is reset under the elastic release of the return spring 219. At this time, the wedge-shaped slider 26 is no longer pressed. Under the elastic stretching of the return spring 1 28, the wedge-shaped slider 26 will move upward. At this time, the top of the locking block 218 abuts against the bottom of the abutment block 1 214, so that the wedge-shaped slider 26 is limited, and the return spring 1 28 continues to be in an elastically compressed state.

[0078] When the wedge-shaped slider 26 is pressed downward, the trigger rack block 224 moves synchronously with the wedge-shaped slider 26 , and at this time, the trigger rack block 224 is located in the clamping groove 25 ;

[0079] At this time, the motor 1 21 is started to rotate the rotating block 22, and the insulating base clamped by the multiple clamping blocks 223 rotates synchronously until the outermost pins of the insulating base contact the baffle, so that the baffle is synchronously displaced through the rotating shaft rod until the contact 1 230 contacts the contact 2 231, so that the motor 1 21 stops moving, thereby completing the positioning between the insulating base and the connecting row;

[0080] After the docking is completed, the transmission gear 38 rotates to drive the transmission rack block 310 to move, so that the sliding block 34 slides into the sliding groove 33, and at the same time drives the stopper 35 to move synchronously, so that the bottom end of the connection row fixed on the stopper 35 and the pin of the insulating base are more tightly in contact;

[0081] At this time, the two electric guide rails 11 are started, and the welding gun nozzles on the two welders 14 are relatively moved through the displacement of the sliding block 12 and the telescopic steering of the telescopic steering device 13, so that the bottom of the connecting row and the pins of the insulating base are clamped by the two welding gun nozzles, and then welding is performed. The above operation is repeated many times, thereby completing the welding between the connecting row and the insulating base;

[0082] Then, the trigger rack block 224 is pressed downward. During the pressing process of the trigger rack block 224, the limit spring 225 is elastically compressed. At the same time, the bottom of the trigger rack block 224 is meshed with the gear rod 226, so that the gear rod 226 rotates. The rotation of the gear rod 226 drives the rack slider 213 to slide upward, so that the second resistance block 215 moves upward until the top of the second resistance block 215 conflicts with the bottom of the first resistance block 214. At this time, the trigger rack block 224 is pressed to the farthest distance.

[0083] When the second contact block 215 moves upward, the second contact block 215 squeezes the locking block 218, causing the locking block 218 to shrink and elastically compress the second return spring 219, until the top of the locking block 218 contacts the bottom of the second contact block 215, and the locking block 218 no longer contacts the bottom of the first contact block 214. Under the elastic stretching action of the return spring 28, the wedge-shaped slider 26 is reset.

[0084] Through the above operation, the quick positioning assembly and the fastening assembly are reset, and then the formed motor flat wire bus is taken out, and the second motor 37 is started again, and the transmission gear 38 is meshed with the second guide gear 39, so that the second guide gear 39 drives the transmission rack block 310 to move in the reverse direction, so that it is reset;

[0085] Repeat the above steps to produce the next motor flat wire bus.
