DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-10 This application is described in further detail.

[0038] According to the related prior art, the stator is wound with winding coils, so wire leads are drawn out of the stator. The wire leads include three outgoing wire terminals and three common terminals. The three outgoing wire terminals are used to connect to the power supply, and therefore the three common terminals need to be twisted together. During stator processing, the outgoing wire terminals and the common terminals are stripped of paint separately, each outgoing wire terminal is twisted, and the three common terminals are twisted together. After the outgoing wire terminals and the twisted common terminals are dipped in tin, each outgoing wire terminal and the twisted common terminals are finally tested for continuity.

[0039] In view of the fact that there are many stator processing steps mentioned above, the stator paint stripping, kinking and tin dipping testing all-in-one machine of the present application can complete all the above stator processing steps at one time, effectively improving the efficiency of stator processing, and does not require extra personnel, effectively saving labor.

[0040] Specifically, a stator paint stripping, kinking, tinning and immersion testing machine, referring to Figure 1 As shown, it includes a frame and a turntable 1 rotatably mounted on the frame, a rotating shaft is provided at the center position of the turntable 1, a CNC dividing disk 2 is provided on the frame, and the rotating shaft of the turntable 1 is connected to the CNC dividing disk 2. The CNC dividing disk 2 can drive the turntable 1 to rotate a fixed angle each time.

[0041] Reference Figure 1 and Figure 3 As shown, a plurality of stator fixing seats 3 are circumferentially arranged on the rim of the turntable 1. The stator fixing seats 3 are used to fix the stator. The stator sleeve locating pins 4 and the stator bracket locating pins 5 are provided on the stator fixing seats 3. The stator sleeve stator pins and the stator bracket locating pins 5 are respectively used to connect with the shaft hole and the locating hole on the stator, thereby realizing the fixation of the stator on the stator fixing seat 3.

[0042] In one embodiment, eight stator fixing seats 3 are provided, and the eight stator fixing seats 3 are arranged at equal intervals on the turntable 1, so that the turntable 1 can be spatially divided into eight processing stations, wherein each station implements a processing process of the stator. After the stator is processed at one station, the turntable 1 rotates and brings the stator to the next station for processing until all processing processes are completed.

[0043] It is worth noting that the first workstation is an installation workstation, which is used to remove the machined stator from the stator fixing seat 3 and fix the stator to be machined onto the stator fixing seat 3 .

[0044] The following is a description of each station in stator processing.

[0045] Reference Figure 1 and Figure 2As shown, a paint stripping assembly 6, a twisting assembly 7, a wire cutting assembly 9, a tinning assembly 10 and a continuity test assembly 11 are sequentially arranged on the frame around the turntable 1. Each stator fixing seat 3 passes through the paint stripping assembly 6, the twisting assembly 7, the wire cutting assembly 9, the tinning assembly 10 and the continuity test assembly 11 one by one to process the wire ends on the fixed stator.

[0046] Reference Figure 1 and Figure 4 As shown, in this application, two paint stripping assemblies 6 are provided, and the two paint stripping assemblies 6 are respectively arranged at the second station and the third station. The paint stripping assembly 6 on the second station is used to strip the paint on the three common ends of the stator, and the paint stripping assembly 6 on the third station is used to strip the paint on the three outgoing wire ends of the stator.

[0047] The paint stripping assembly 6 includes a first paint stripping servo slide 61 provided on a frame, a second paint stripping servo slide 62 provided on the first paint stripping servo slide 61, and a third paint stripping servo slide 63 provided on the second paint stripping servo slide 62. A paint stripping unit 64 is provided on the third paint stripping servo slide 63. The first paint stripping servo slide 61, the second paint stripping servo slide 62, and the third paint stripping servo slide 63 are used to drive the paint stripping unit 64 to move forward, backward, left, right, and up and down. In this embodiment, the first paint stripping servo slide 61 is used to drive the second paint stripping servo slide 62 to move forward and backward, the second paint stripping servo slide 62 is used to drive the third paint stripping servo slide 63 to move up and down, and the third paint stripping servo slide 63 is used to drive the paint stripping unit 64 to move left and right, thereby achieving the front and back, left and right, and up and down movement of the paint stripping unit 64 below the stator fixing seat 3.

[0048] The first paint stripping servo slide 61 includes a servo track and a sliding table slidably installed on the servo track. A transmission screw is rotatably installed on the servo track, and the transmission screw is threadedly connected to the sliding table. A servo motor connected to the transmission screw is provided on the servo track. Thus, the transmission screw is driven to rotate by the servo motor, and the transmission screw then drives the sliding table to move on the servo track.

[0049] It is worth noting that the first paint stripping servo slide 61 is arranged on the frame, that is, the servo track of the first paint stripping servo slide 61 is fixed to the frame via a fixing plate. The second paint stripping servo slide 62 is arranged on the first paint stripping servo slide 61, that is, the servo track of the second paint stripping servo slide 62 is fixed to the sliding table of the first paint stripping servo slide 61. The third paint stripping servo slide 63 is arranged on the second paint stripping servo slide 62, that is, the servo track of the third paint stripping servo slide 63 is fixed to the sliding table of the second paint stripping servo slide 62. The paint stripping unit 64 is arranged on the third paint stripping servo slide 63, that is, the paint stripping unit 64 is arranged on the sliding table of the third paint stripping servo slide 63.

[0050] The first paint stripping servo slide 61 , the second paint stripping servo slide 62 and the third paint stripping servo slide 63 have the same structure, and the present embodiment does not repeat the structure of the second paint stripping servo slide 62 and the third paint stripping servo slide 63 .

[0051] Reference Figure 4 As shown, the paint stripping unit 64 includes a paint stripping support frame 641 and two paint stripping rollers 642. The paint stripping support frame 641 is fixedly mounted on the slide platform of the third paint stripping servo slide 63. The two paint stripping rollers 642 are rotatably mounted on the paint stripping support frame 641. Specifically, the paint stripping support frame 641 is provided with two rotatable mounting blocks 644. The paint stripping rollers 642 are provided with a rotating shaft 643, and the paint stripping rollers 642 are rotatably mounted on the rotating mounting blocks 644 via the rotating shaft 643. The two paint stripping rollers 642 are arranged side by side, with the wheel surfaces of the two paint stripping rollers 642 facing each other and forming a paint stripping gap between the wheel surfaces of the two paint stripping rollers 642. Furthermore, the paint stripping support frame 641 is provided with a paint stripping drive unit 65 for driving the two paint stripping rollers 642 to rotate in opposite directions.

[0052] The paint stripping drive unit 65 includes a paint stripping drive motor 651, which is fixedly mounted on the paint stripping support frame 641. The output shaft of the paint stripping drive motor 651 is connected to the rotating shaft 643 of one of the paint stripping rollers 642 via a gear chain structure. A driving gear 652 is mounted on the rotating shaft 643 of one of the paint stripping rollers 642, and a driven gear 653 is mounted on the rotating shaft 643 of the other paint stripping roller 642, which meshes with the driving gear 652. Thus, the paint stripping drive motor 651 drives one of the paint stripping rollers 642 to rotate, and the meshing of the driving gear 652 and the driven gear 653 drives the other paint stripping roller 642 to rotate, so that the two paint stripping rollers 642 rotate in opposite directions.

[0053] Reference Figure 4 As shown, the paint stripping support frame 641 is provided with a paint collection hood 66 that covers the outside of two paint stripping rollers 642. The paint collection hood 66 is located below the two paint stripping rollers 642. The bottom of the paint collection hood 66 is provided with a paint collection port. The bottom of the paint collection hood 66 is an inclined surface that converges toward the paint collection port. The paint collection port is connected to the paint collection port. Therefore, after the paint stripping rollers 642 remove the enameled wire from the thread end, the paint will fall into the paint collection hood 66, then enter the paint collection port and be sucked away by the paint suction pipe.

[0054] It is worth noting that the two paint stripping assemblies 6 have the same structure, and this application will not repeat them. When the two paint stripping assemblies 6 are in operation, they can effectively strip the paint off the enameled wire on the stator wire head by moving forward, backward, left, right, and up and down.

[0055] Reference Figure 2 and Figure 5As shown, the twisting assembly 7 is set at the fourth station. The twisting assembly 7 is used to twist the paint-stripped wire ends and straighten the wire ends in the vertical direction. The twisting assembly 7 not only twists and straightens the three outgoing wire ends of the stator wire ends, but also twists and straightens the three common ends together.

[0056] The kinking assembly 7 includes a first kinking servo slide 71 arranged on the frame, a second kinking servo slide 72 arranged on the first kinking servo slide 71, and a third kinking servo slide 73 arranged on the second kinking servo slide 72. The third kinking servo slide 73 is provided with a kinking part 74. The first kinking servo slide 71, the second kinking servo slide 72 and the third kinking servo slide 73 are used to drive the kinking part 74 to move forward, backward, left, right and up and down.

[0057] The first kink servo slide 71 includes a servo track, a transmission screw, a slide table, and a servo motor. The slide table is slidably mounted on the servo track, the transmission screw is rotatably mounted on the servo track, and the transmission screw is threadedly connected to the slide table. The servo motor is fixed to the servo track and connected to the transmission screw. The servo motor drives the transmission screw to rotate, thereby achieving movement of the slide table on the servo track.

[0058] The first kink servo slide 71 has the same structure as the second kink servo slide and the third kink servo slide 73, and will not be repeated in this embodiment. The first kink servo slide 71 is arranged on the frame, that is, the servo track of the first kink servo slide 71 is fixed on the frame. The second kink servo slide 72 is arranged on the first kink servo slide 71, that is, the servo track of the second kink servo slide 72 is fixed on the sliding table of the first kink servo slide 71. The third kink servo slide 73 is arranged on the second kink servo slide 72, that is, the servo track of the third kink servo slide 73 is fixed on the sliding table of the second kink servo slide 72. The kink portion 74 is arranged on the third kink servo slide 73, that is, the kink portion 74 is arranged on the sliding table of the third kink servo slide 73.

[0059] Reference Figure 5 As shown, the kinking part 74 includes a kinking support frame 741 and a kinking rotation motor 742, the kinking support frame 741 is fixed on the sliding table of the third kinking servo slide 73, and the kinking rotation motor 742 is fixed on the kinking support frame 741, wherein the kinking rotation motor 742 is connected to the kinking finger cylinder 743, and the kinking finger cylinder 743 is connected to the kinking claw 744.

[0060] It is worth noting that, referring to Figure 6As shown, a support base 745 is fixed on the kink support frame 741, and a rotating cavity is passed through the middle of the support base 745 along its axial direction. A rotating platform 746 is rotatably installed on the support base 745, and the rotating platform 746 is provided with a connecting shaft 747 which is inserted into the rotating cavity and connected to the kink rotating motor 742.

[0061] A first air vent 748 and a second air vent 749 are provided on the support base 745, and the first air vent 748 and the second air vent 749 are connected to the air pipe of the external air source. A third air vent 750 and a fourth air vent 751 are provided on the rotating table 746, and the third air vent 750 and the fourth air vent 751 are respectively connected to the two air ports of the kinking finger cylinder 743 through the air pipe. The two air ports of the kinking finger cylinder 743 are used to realize air intake and exhaust, thereby realizing the opening and closing of the kinking claw 744.

[0062] The connecting shaft 747 is provided with a first air duct 752, which communicates with the first and third air ducts 748 and 750, respectively, and a second air duct 753, which communicates with the second and fourth air ducts 749 and 751, respectively. Annular grooves 754 are provided in the rotating chamber at corresponding locations of the first and second air ducts 748 and 749, and sealing rings 755 are provided at the upper and lower ends of the connecting shaft 747 and the rotating chamber. Thus, through the arrangement of the support base 745 and the rotating platform 746, the kink rotating motor 742 can drive the kink finger cylinder 743 to rotate freely without worrying about tangling of the kink finger cylinder 743 due to the air pipe connection.

[0063] The twisting unit 74 clamps the three stator wire ends and twists them. It can move up and down under the action of the third twisting servo slide 73, thereby twisting and straightening the wire ends at the same time. The second twisting servo slide 72 and the third twisting servo slide 73 move to each wire end to twist and straighten them.

[0064] The stator wire head has three common ends, so when twisting the three common ends, the three common ends need to be integrated together first.

[0065] Reference Figure 2 and Figure 7 As shown, the frame is provided with a line-straightening assembly 8 on one side of the twisting assembly 7. The line-straightening assembly 8 is used to integrate the three common ends of the wire ends together. Specifically, the line-straightening assembly 8 first integrates the first common end to the corresponding position, and then integrates the second common end and the first common end together. After the twisting assembly 7 twists and straightens the first common end and the second common end, the line-straightening assembly 8 gathers the third common end to the first and second common ends that have been twisted, and the twisting assembly 7 performs another twisting to twist the three common ends together.

[0066] The line aligning assembly 8 includes a first line aligning servo slide 81 provided on a frame, and a second line aligning servo slide 82 provided on the first line aligning servo slide 81 . A line aligning portion 83 is provided on the second line aligning servo slide 82 .

The sliding platform is slidably mounted on the servo track, the drive screw is rotatably mounted on the servo track, and the drive screw is threadedly connected to the sliding platform. The servo motor is mounted on the servo track and connected to the drive screw. The structures of the first servo platform 81 and the second servo platform 82 are identical and will not be described in detail in this embodiment.

[0068] The first line-aligning servo slide 81 is mounted on a machine frame, i.e., its servo rails are fixed to the frame. The second line-aligning servo slide 82 is mounted on the first line-aligning servo slide 81, i.e., its servo rails are fixed to the slide table of the first line-aligning servo slide 81. The line-aligning unit 83 is mounted on the second line-aligning servo slide 82, i.e., its servo rails are fixed to the slide table of the second line-aligning servo slide 82.

[0069] Reference Figure 7 As shown, the line straightening part 83 includes a line straightening support frame 831 arranged on the second line straightening servo slide 82, and a line straightening cylinder 832 is arranged on the line straightening support frame 831. The output rod of the line straightening cylinder 832 is connected to the line straightening finger cylinder 833, and the line straightening finger cylinder 833 is connected to the line straightening claw 834. The line straightening cylinder 832 is used to provide a driving force for the line straightening finger cylinder 833 toward the side of the stator fixing seat 3, so that the line straightening claw 834 can integrate the first common end, the second common end, and the third common end together.

[0070] Reference Figure 2 and Figure 8 As shown, the wire cutting assembly 9 is set on the fifth work station. The wire cutting assembly 9 is used to cut the three twisted outgoing wire ends and the three twisted common ends to keep the end faces flush, thereby facilitating subsequent soldering.

There are two thread trimming columns 91, which are fixed to the frame in the vertical direction. There are two thread trimming lifting cylinders 92, which are fixed to the thread trimming columns 91. The thread trimming support frame 93 is connected to the output rod of the thread trimming lifting cylinder 92. Thus, the thread trimming support frame 93 can move up and down under the action of the thread trimming lifting cylinder 92.

[0072] The first wire shearing plate 94 is slidably mounted on the wire shearing support frame 93, and the second wire shearing plate 95 is slidably mounted on the wire shearing support frame 93. The first wire shearing plate 94 and the second wire shearing plate 95 are located on the same horizontal plane. Four first cutters 96 are provided on the first wire shearing plate 94, and four second cutters 97 are provided on the second wire shearing plate 95. The positions of the first cutters 96 and the second cutters 97 are opposite to each other. The positions of the first cutters 96 and the second cutters 97 on the first wire shearing plate 94 and the second wire shearing plate 95 are respectively below the three wire outlet ends and the three common ends twisted together.
