Description

Technical Field

[0001] This invention belongs to the field of motor processing, specifically referring to a wire bonding clamping device for installing motor wires in a motor. Background Technology

[0002] Currently, the manual operation of motor wire welding is quite cumbersome. The specific steps are: manually picking up the motor and placing it on a fixed support block, then picking up the motor wire and simultaneously welding it to the motor stand, welding one wire after another. This welding process results in inconsistent welding time, frequent product changes, and low welding safety. To solve these problems, Chinese patent CN206455347U discloses a motor wire welding fixture, which uses a mounting cavity for placing the motor and a clamp for pressing the motor wire to position the motor and motor wire before welding. This structure can achieve the positioning of the motor and motor wire, but since the motor wire generally needs to be welded to the outer surface of the motor stand, when the positions of the motor stand and motor wire are fixed, the welding position is located on the side of each motor stand, which is very inconvenient and the welding quality is difficult to control. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a wire bonding clamping device that can complete the wire bonding work of a specified motor. During welding, the positioned motor and motor wire are rotated so that the welding position is at the top of the clamping device in a horizontal setting, which facilitates welding and ensures welding quality. Several motors can be welded at one time, which improves work efficiency and work quality.

[0004] To solve the above-mentioned technical problems, the present invention provides a wire bonding clamping device, including a support assembly, a plurality of clamping assemblies, and a transmission assembly, wherein: the plurality of clamping assemblies are rotatably mounted sequentially on the support assembly, and the clamping assemblies are spaced apart from each other; the transmission assembly is mounted on the support assembly and connected to all the clamping assemblies, and drives the clamping assemblies to rotate forward or backward relative to the support assembly; the clamping assemblies are used to hold and fix a motor and motor wire, so that the motor wire is located at the welding position of the motor stand; during welding, the transmission assembly drives the clamping assemblies to rotate, so that the motor stand and motor wire are located at a convenient welding position for welding.

Through the contact of the inclined surfaces, the left and right wiring devices are driven to move along the linear guide rails 39 in opposite directions to increase the distance between them and the motor feet, facilitating wiring. When wiring is completed, the lifting device retracts, and under the action of tension springs 37, the two wiring devices return to their original positions, so that the installed motor wires are respectively attached to the outer side of the motor feet.

[0038] The specific structure of clamping assembly 2 is as follows:

[0039] Bearing 23 is installed in the mounting hole on the roller mounting plate 20, and bearing 34 is installed in the corresponding mounting hole on the mounting panel 6. The clamp mounting base 36 has a U-shaped structure, and the bottom of the clamp mounting base 36 is a flat plate structure. A rear pressure shaft block 24 and a front pressure shaft block 33 are respectively installed on its two side walls. A follower shaft 35 is installed on the side wall of the clamp mounting base 36 located on the side of the mounting panel 6. The follower shaft 35 is rotatably mounted in the bearing 34. A drive shaft 49 is installed on the side wall of the clamp mounting base 36 located on the side of the roller mounting plate 20. The drive shaft 49 can drive through the bearing 23 set on the roller mounting plate 20 and extend out to the other side of the roller mounting plate 20. A synchronous pulley 22 is set on the drive shaft 49 on the other side of the roller mounting plate 20. A mounting base plate 38 is fixedly installed at the bottom of the clamp mounting base 36. A motor placement seat 25 is fixedly installed on the mounting base plate 38. The motor placement seat 25 is located on the side close to the roller mounting plate 20. The motor mounting base 25 is a box-shaped structure, its shape matching the motor shape. A magnet 26 is fixedly installed at the bottom of the motor mounting base 25. When the motor is placed in the motor mounting base 25, the magnet 26 can attract and fix the motor. The end wall of the motor mounting base 25 facing the mounting panel 6 has a notch for the motor's legs to extend out. A support block is provided outside the notch, and the two legs of the motor that need to be soldered rest on the support block.

[0040] A linear guide rail 39 is provided on the mounting base plate 38 between the support block of the motor mounting seat 25 and the mounting panel 6. The linear displacement direction of the linear guide rail 39 is the direction of the line connecting the two left and right upright end faces of the motor. Two guide rail blocks 40 are provided on the linear guide rail 39, and a left wire clamping mounting plate 42 and a right wire clamping mounting plate 31 are respectively fixed on the two guide rail blocks 40. Tension spring screws 32 are respectively provided on the outer side of the left wire clamping mounting plate 42 and the right wire clamping mounting plate 31, and the two ends of the tension springs 37 are respectively hung on the tension spring screws 32. A left-side wire clamping movable block 44 and a right-side wire clamping movable block 29 are respectively provided on the left-side wire clamping mounting plate 42 and the right-side wire clamping mounting plate 31. A left-side wire clamping fixed block 43 and a left-side spring fixed block 41 are respectively provided on both sides of the left-side wire clamping movable block 44. A right-side wire clamping fixed block 28 and a right-side spring fixed block 30 are respectively provided on both sides of the right-side wire clamping movable block 29. The left-side wire clamping fixed block 43 and the left-side spring fixed block 41 are fixedly mounted on the left-side wire clamping mounting plate 42, and the right-side wire clamping fixed block 28 and the right-side spring fixed block 30 are fixedly mounted on the right-side wire clamping mounting plate 31. A sealing plate 27 is provided on one side of each of the two wire clamping fixed blocks (28, 43), and a sealing ring 46 is provided on the other side. An air passage is provided between the wire clamping fixed blocks. The air passage is sealed by the sealing plate and the sealing ring. The air passage is connected to an air pipe connector 57, and air is supplied into the air passage through the air pipe connector 57. A push rod 45 is provided between the wire clamping fixing block and the wire clamping movable block. One end of the push rod 45 is fixedly connected to the wire clamping movable block, and the other end abuts against the sealing ring. This closes one side of the right wire clamping fixing block 28 and the left wire clamping fixing block 43. A spring 56 is provided between the wire clamping movable block and the spring fixing block. The left wire clamping movable block 44 and the right wire clamping movable block 29 are slidably mounted on the left wire clamping mounting plate 42 and the right wire clamping mounting plate 31, respectively. A wire feeding groove is provided on one end of each of the two left and right wire clamping fixing blocks (28, 43) facing the left and right wire clamping movable blocks (44, 29). At the open end of the wire feeding groove, the left and right wire clamping movable blocks (44, 29) are provided with clamping blocks that extend into the wire feeding groove corresponding to the position of the wire feeding groove. Both the clamping blocks and the open end of the wire feeding groove are set as guide slopes to facilitate the pressing of the motor wire. Compressed air is supplied to the two clamping blocks (28, 43), causing the sealing rings to bulge towards the left and right clamping blocks (44, 29) through the air passages. This drives the push rod 45 to move the left and right clamping blocks (44, 29) towards their adjacent spring fixing blocks, compressing the spring 56 and increasing the distance between the left and right clamping blocks (44, 29) and the left and right clamping blocks (28, 43). This increases the spacing of the wire feeding slots, making it easier for manual removal of the motor with the welded motor wire from the wire feeding slots. When inserting the motor wire, it is manually pressed into the wire feeding slot. During this pressing process, the clamping blocks move outwards. After the motor wire is inserted, the clamping blocks clamp the motor wire under the action of the spring 56.

[0041] Through holes are provided in the fixture mounting base 36 and the mounting base plate 38. A lifting mounting block 48 is installed in the through holes, and a lifting shaft 47 is slidably installed in the lifting mounting block 48. The upper part of the lifting shaft 47 is a lifting support shaft (not shown) with corresponding left and right clamping wire mounting plates. The top of the lifting support shaft is set with a sloping structure. The left and right clamping wire mounting plates are provided with abutting holes at the positions corresponding to the lifting support shaft. The abutting holes are provided with abutting sloping structures. The lifting shaft 47 is located on the lifting plate 18. When lifting is required, the lifting plate 18 is lifted by the lifting platform (not shown) below the lifting support plate 17, causing it to move upward along the linear guide rail 12. The lifting shaft 47 is moved upward by the lifting plate 18. The upward movement of the lifting shaft 47 abuts against the clamping wire mounting plates, forcing the left and right clamping wire mounting plates to move away from each other along the linear guide rail 39, increasing the distance between them and the two sides of the support block where the motor stand is placed.

[0042] Transmission component 3, see Figures 8 to 9 It includes a drive shaft 49, a tensioning wheel 50, a belt 51, left and right tensioning wheels 52, an adjusting plate 53, a drive wheel 54, and a servo motor 55.

[0043] The synchronous pulley 22 of each clamping assembly 2 is located on the back side of the roller mounting plate 20 away from the mounting panel 6. The synchronous pulley 22 is mounted on the drive shaft 49, which is connected to the motor mounting base 25. A drive wheel 54 is mounted on the same side of the roller mounting plate 20 where the synchronous pulley 22 is mounted. The drive wheel 54 is connected to a servo motor 55, which drives the drive wheel 54 to rotate. The drive wheel 54 is connected to the synchronous pulley 22 via a belt 51. Tensioning pulleys (50, 52) are provided on the roller mounting plate 20. The belt tension is adjusted by tensioning pulley 50, and the belt direction is adjusted by tensioning pulley 52. ​​An adjusting plate 53 is also mounted on the roller mounting plate 20. The tensioning pulleys 50 located on both sides of the drive wheel 54 are mounted on the adjusting plate 53. The adjusting plate 53 has adjusting grooves, allowing the tensioning pulleys 50 to move along the adjusting grooves. After adjustment, they are fixed with fastening screws.

[0044] The transmission assembly 3 drives the drive wheel 54 to rotate via the servo motor 55, which in turn drives the synchronous wheel 22 to rotate synchronously, and the synchronous wheel 22 drives the clamping assembly 2 to rotate synchronously. The transmission assembly 3 can rotate in both forward and reverse directions.

[0045] The workflow of this invention:

[0046] 1) Turn on the power switch and connect the air source. Manually place 8 motors into the motor mounting base 25 one by one, and use magnet 26 to hold them in place. At this time, the lifting plate 18 drives the lifting shaft 47 to push upward along the guide rail 12, causing the left wire clamping mounting plate 42 and the right wire clamping mounting plate 31 to move to the left and right sides along the linear guide rail 39. After the lifting shaft 47 is in place, manually take a motor wire and place it between the left wire clamping movable block 44 and the left wire clamping fixed block 43. When forcefully pushing it down along the wire placement groove, the left wire clamping movable block 44 moves to the left along the guide rail 39. At this time, the spring 56 in the left spring fixed block 41 is in a contracted state, pressing against the left wire clamping movable block 44. The motor wire is inserted into the left wire clamping movable block 44 and the left wire clamping fixed block 43. When the middle clamping position is reached, take another motor wire and place it in the middle position between the right clamping fixing block 28 and the right clamping movable block 29. As it is inserted downwards along the wire feeding groove, the right clamping movable block 29 moves to the right along the guide rail 39. At this time, the spring 56 in the right spring fixing block 30 is in a contracted state, pressing against the right clamping movable block 29. When the motor wire is inserted into the middle clamping position between the right clamping fixing block 28 and the right clamping movable block 29, manually insert the wires of 8 motors into the corresponding clamping positions in sequence. Then, the lifting plate 18 moves downwards along the linear guide rail 12, the lifting shaft 47 loses its lifting force, and retracts under the action of gravity. The tension spring 37 moves the left clamping mounting plate 42 and the right clamping mounting plate 31 back along the guide rail 39. When the left and right sides When the sealing plate 27 contacts, it is in position. At this time, the motor wires on both sides are aligned with the two uprights of the motor. Then, the servo motor 55 starts rotating forward, driving the drive wheel 54 to rotate. Through the belt 51, it drives the tension wheel 50 and the synchronous wheel 49, and the left and right tension wheels 52 to rotate, causing the eight clamping components to rotate 90° to the right as a whole. At this time, one upright of the motor and the welding wire part are at the top of the welding wire clamping device, in a convenient welding position. Then, the motor wire is welded. After welding one upright, the servo motor 55 reverses 180° to adjust the other upright and the welding wire part to the welding position for welding. After welding, the servo motor 55 starts rotating forward, rotating 90° to put the clamping component 2 in a flat position. Then, the air pipe connector 57 is clamped to the right. When the wire fixing block 28 and the left wire clamping fixing block 43 are vented, the push rod 45 inside pushes outward to the left and right respectively. The left wire clamping movable block 44 moves to the right along the guide rail 39, and the right wire clamping movable block 29 moves to the right along the guide rail 39. When the left and right springs 56 retract to their positions, the left wire clamping movable block 44 fits against the left spring fixing block 42, and the right wire clamping movable block 29 fits against the right spring fixing block 30. Then, the 8 motors with completed wire welding can be manually removed. After removal, the gas in the air pipe connector is disconnected, and the left and right springs 56 extend, causing the left wire clamping movable block 44 to move back and fit against the left wire clamping fixing block 43, and the right wire clamping movable block 29 to move back and fit against the right wire clamping fixing block 28. At this point, the wire welding clamping is completed.
