DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] like Figure 1-9 As shown, a paint dripping electric heating mechanism comprises two assembly frames 1 and two cross frames 3, the two cross frames 3 are symmetrically mounted on the two assembly frames 1, a rotating bearing seat 9 is fixed on the two cross frames 3, the rotating bearing seat 9 is rotatably connected with a transmission shaft 91, the two transmission shafts 91 are connected with a mounting plate 2, a circular hole is opened at the center of the mounting plate 2, and a three-jaw chuck 14 for clamping an iron core 13 is arranged in the circular hole, the three-jaw chuck 14 is driven by a motor 11 located on the mounting plate 2 to drive the three-jaw chuck 14 to rotate, and a locking assembly 6 for limiting the rotation of the three-jaw chuck 14 is arranged on the mounting plate 2, so that when the motor 11 is driven, the three-jaw chuck 14 clamps or releases the iron core 13;

[0032] An electric heating component 5 inserted into the iron core 13 is arranged in the circular hole. The electric heating component 5 is fixed on the mounting plate 2 and can be displaced along the axial direction of the iron core 13.

[0033] An angle control component 7 for adjusting the tilt angle of the mounting plate 2 is provided on one side of the cross frame 3;

[0034] When in use, the three-jaw chuck 14 is locked by the locking assembly 6, the robot grabs the iron core 13 and sets the iron core 13 on the electric heating assembly 5, the motor 11 drives the three-jaw chuck 14 to work, and the three-jaw chuck 14 clamps the iron core 13. When paint dripping is required, the angle control assembly 7 is used to adjust the inclination angle of the mounting plate 2 according to the required paint dripping angle to ensure the paint dripping effect;

[0035] After the adjustment is completed, the electric heating component 5 heats the iron core 13, the locking component 6 no longer restricts the three-jaw chuck 14, the motor 11 drives the three-jaw chuck 14 to rotate, and the three-jaw chuck 14 drives the iron core 13 to rotate together. The rotation of the iron core 13 can ensure uniform heating. When the iron core 13 reaches a suitable paint dripping temperature, the iron core 13 continues to rotate, and the external paint dripping mechanism drips paint on the iron core 13. During the paint dripping process, the iron core 13 continues to rotate to ensure uniform paint dripping.

[0036] The purpose of heating the iron core 13 is achieved by the electric heating component 5, and when dripping paint, the curing speed can also be accelerated to improve the working speed.

[0037] In this embodiment, a bearing connection assembly 8 is disposed in the circular hole, a three-jaw chuck 14 is disposed on the bearing connection assembly 8, and a locking assembly 6 can limit the rotation of the bearing connection assembly 8;

[0038] When in use, the three-turn chuck is rotationally connected to the mounting plate 2 through the bearing connection assembly 8, and the three-jaw chuck 14 is restricted in rotation through the cooperation of the locking assembly 6 and the bearing connection assembly 8, thereby ensuring use.

[0039] In this embodiment, the bearing connection assembly 8 includes a cross roller bearing 82, a first bearing retaining ring 81 and a second bearing retaining ring 83, the cross roller bearing 82 is rotatably embedded in the circular hole, and the first bearing retaining ring 81 and the second bearing retaining ring 83 are respectively fixed at both ends of the cross roller bearing 82, the three-jaw chuck 14 is arranged on the second bearing retaining ring 83, and the locking assembly 6 is connected to the first bearing retaining ring 81;

[0040] When in use, the locking assembly 6 limits the rotation of the first bearing retaining ring 81. Since the first bearing retaining ring 81 and the second bearing retaining ring 83 are fixed at both ends of the cross roller bearing 82, the second bearing retaining ring 83 cannot rotate. At this time, the three-jaw chuck 14 cannot rotate. When the three-jaw chuck 14 needs to rotate, the locking assembly 6 is controlled to no longer limit the rotation of the first bearing retaining ring 81.

[0041] In this embodiment, the three-jaw chuck 14 includes a chuck body 141 coaxially fixed on the second bearing retaining ring 83, a chuck gear 143 rotatably connected to the chuck body 141, and claws 142 arranged on the chuck body 141 in a ring array with the center of the chuck body 141 as the center, the claws 142 are slidably connected to the chuck body 141, and the chuck gear 143 is provided with a tooth groove that meshes with the claw 142. The tooth groove is in a planar spiral shape and the center is concentric with the center of the chuck gear 143. The output shaft of the motor 11 is connected to the gear 12 that meshes with the chuck gear 143, and the number of the claws 142 is three;

[0042] When it is necessary to clamp the iron core 13, the locking assembly 6 limits the rotation of the second retaining ring. At this time, the chuck body 141 cannot rotate, and the motor 11 drives the chuck gear 143 to rotate. The claw 142 moves along the tooth groove and gradually shifts toward the center of the chuck body 141, so that the claw 142 clamps the iron core 13. When the clamping is completed, the claw 142 abuts against the iron core 13. When rotation is required, the locking assembly 6 no longer limits the rotation of the second retaining ring. Since the claw 142 cannot continue to rotate, the chuck gear 143 can drive the claw 142 and the chuck body 141 to rotate, so that the iron core 13 rotates, and when the claw 142 rotates, under the friction between the claw 142 and the tooth groove, the claw 142 can maintain the clamping of the iron core 13.

[0043] In this embodiment, the locking assembly 6 includes an origin positioning block 63 fixed on the first bearing retaining ring 81, a cylinder 61 fixed on the mounting plate 2, and a fixed rod 62 fixed to the cylinder 61. The origin positioning block 63 is arranged on the same side as the cylinder 61 and the origin positioning block 63 is provided with a through hole for the fixed rod 62 to be inserted.

[0044] When in use, the cylinder 61 pushes the fixed rod 62 to be inserted into the through hole of the origin positioning block 63. At this time, the origin positioning block 63 cannot rotate, so that the first bearing retaining ring 81 cannot rotate. When the first bearing retaining ring 81 needs to rotate, the cylinder 61 controls the fixed rod 62 to be separated from the through hole.

[0045] When it is necessary to restrict the rotation of the first bearing retaining ring 81 for a second time, the motor 11 controls the first bearing retaining ring 81 to drive the origin positioning block 63 to reset, so as to ensure that the fixed rod 62 and the through hole can be normally plugged.

[0046] In this embodiment, the electric heating assembly 5 includes a linear module fixed on the mounting plate 2, a fixed fixture seat 52 slidably arranged on the linear module, a heating coil 53 fixed on the fixed fixture seat 52, and a protective tube 54 sleeved on the outside of the heating coil 53, the protective tube 54 is fixed on the fixed fixture seat 52, the protective tube 54 is coaxially arranged with the first bearing retaining ring 81, and the lead wire of the heating coil 53 is connected to two power-carrying contacts 51;

[0047] When in use, the power-on connector 51 is connected to the electrical equipment to control the heating of the electric heating component 5. Then the robot grabs the iron core 13 and puts it on the protective tube 54. At this time, the heating coil 53 is located inside the iron core 13. Then, the linear module drives the heating coil 53, the protective tube 54 and the iron core 13 to move into the three-jaw chuck 14 through the fixed tooling seat 52. The three-jaw chuck 14 clamps the iron core 13 and drives the iron core 13 to rotate. Then, the heating coil 53 is energized through the power-on connector 51 to achieve heating of the iron core 13. When the heating is completed, the three-jaw chuck 14 no longer clamps the iron core 13. The linear module drives the iron core 13 to reset. The robot removes the processed iron core 13 and puts a new iron core 13 on the protective tube 54.

[0048] By providing the protective tube 54, it is prevented that the insulating paint drips onto the heating coil 53, thereby preventing the use effect from being affected.

[0049] In this embodiment, the angle control assembly 7 includes a base 4 arranged between two cross frames 3, a servo electric cylinder 71 rotatably mounted on the base 4, a follower connecting column 76 fixed on the mounting plate 2, a support plate 74 fixed on the cross frame 3, and an arc-shaped slide groove 75 provided on the support plate 74. The servo electric cylinder 71 is rotatably connected to the mounting plate 2, the follower connecting column 76 is slidably connected in the arc-shaped slide groove 75, the center of the arc-shaped slide groove 75 is concentric with the rotation center of the mounting plate 2, and the base 4 is arranged on one side of the mounting plate 2 where the electric heating assembly 5 is mounted;

[0050] When in use, the servo electric cylinder 71 is controlled to extend or retract according to the tilt angle that needs to be adjusted for the mounting plate 2. The servo electric cylinder 71 drives the mounting plate 2 to rotate about the rotation center of the mounting plate 2, and the follower connecting column 76 is displaced along the arc-shaped slide groove 75, thereby ensuring the adjustment of the mounting plate 2. The maximum tilt angle of the mounting plate 2 is limited by the setting of the follower connecting column 76 and the arc-shaped slide groove 75 to avoid excessive tilt angle.

[0051] In this embodiment, the output end of the servo electric cylinder 71 is connected to a fisheye bearing 72, and the mounting plate 2 is connected to a connecting piece 73 rotatably connected to the fisheye bearing 72. When in use, the mounting plate 2 and the servo electric cylinder 71 are rotatably connected through the fisheye bearing 72 and the connecting piece 73 to ensure transmission.

[0052] In this embodiment, the mounting plate 2 is provided with a protective cover 10 with one end located in the circular hole, and the three-jaw chuck 14, the locking assembly 6, and the electric heating assembly 5 do not contact the protective cover 10 when working; when in use, the insulating paint is caught by the protective cover 10 to prevent the insulating paint from dripping onto the bearing connection assembly 8, thereby ensuring the normal use of the bearing connection assembly 8 and extending its service life.

[0053] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein; any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
