Description

Technical Field

[0001] The invention relates to the field of winding machines, and in particular to a precision winding machine for an accelerometer sensor coil and a winding process thereof. Background Art

[0002] The wire material of the accelerometer sensor coil is fine, and its coil skeleton is small and has low rigidity, which makes it easy to deform the skeleton during the winding process, resulting in uneven skeleton winding and inconsistent winding tightness. The automatic winding equipment currently on the market clamps the coil skeleton in a fixture for winding, but the skeleton with weak rigidity is prone to being clamped flat. In order to solve the problem of the weak rigid skeleton being clamped flat, some later winding equipment first put the coil skeleton on the winding spindle and then wind it. The winding equipment using this method is prone to bruises or damage to the inner hole of the skeleton when loading and unloading the skeleton. In order to avoid the problem of bruises caused by the skeleton and the winding spindle being too tightly set, the manufacturer generally designs the size of the winding spindle to be smaller, which causes the skeleton set to shake easily when winding on the winding spindle, resulting in uneven winding and loose winding, which makes it have problems such as low product yield, high production cost and poor winding effect. Summary of the invention

Any structure that can output reciprocating motion can be tried and is not specifically limited here.

[0071] In another embodiment, the present invention also provides a winding process / winding method of a precision winding machine for an accelerometer sensor coil: first, the clamp 64 is placed on the feeding jig 63 in the clamp feeding mechanism 6, and the feeding jig 63 can move longitudinally through the clamp feeding screw assembly 65 and driven by the clamp feeding motor 67, so that it can be transported and fed through the clamp feeding mechanism 6, and the clamp feeding mechanism 6 can prepare the clamp 64 for the clamp loading and unloading robot 5.

[0072] When the fixture loading and unloading robot 5 clamps the fixture 64 from the fixture feeding mechanism 6 and installs one end of the fixture 64 into the fixture sleeve 84 in the winding spindle 8, the unloading plate fork 497 in the fixture unloading mechanism 4 can push the fixture unloading sleeve 82 when it is moved in the direction of the fixture unloading sleeve 82 under the joint drive of the fixture unloading X-axis motor 49 and the fixture unloading Y-axis motor 44, so that the marble 85 can be displaced toward the inner diameter of the fixture sleeve 84 under the pressure of the fixture unloading sleeve 82 and fall into the circular groove in the fixture 64, so as to achieve the clamping and anti-falling of the fixture 64. Then, the unloading plate fork 497 in the fixture unloading mechanism 4 is reset under the joint drive of the fixture unloading X-axis motor 49 and the fixture unloading Y-axis motor 44, which realizes that the fixture 64 can be quickly and firmly installed on the winding spindle 8.

[0073] When the winding transposition spindle 27 in the winding mechanism 2 rotates under the drive of the winding transposition motor 13, the positions of the two winding spindles 8 can be switched, so that the winding spindle 8 equipped with the clamp 64 can rotate to one side of the wire arrangement mechanism 3, and the winding spindle 8 without the clamp 64 rotates to one side of the clamp unloading mechanism 4, so as to facilitate the installation of the next clamp 64. The winding transposition spindle 27 can drive the rotation limit block 28 to rotate synchronously during the rotation process. When the rotation limit block 28 touches the upper limit block 24 or the lower limit block 25, the rotation angle of the winding transposition spindle 27 can be limited to stop the rotation, so as to ensure that the dual winding spindles 8 can accurately switch positions.

[0074] After the wire is led from the tensioner 16, it is guided and arranged through the various guide wheels in the wire arranging mechanism 3. When the wire clamping and throwing cylinder 790 in the wire pulling mechanism 7 clamps the wire end and is used in conjunction with the wire arranging mechanism 3, the wire arranging effect of the wire arranging mechanism 3 can be ensured to be good; the guide needle 3990 in the wire arranging mechanism 3 can be flipped through the guide needle rotating shaft 398 and driven by the guide needle rotating angle cylinder 3992, so that the guide needle 3990 can be flipped to a position relative to the clamp 64 (that is, in a position relative to the same straight line), and then, when the guide needle 3990 makes a circular motion under the joint drive of the wire arranging X-axis motor 37, the wire arranging Y-axis motor 33 and the wire arranging Z-axis motor 39, it can first wrap the wire around the clamp 64 and then lead the wire into the skeleton in the clamp 64, preparing for the wire arranging operation. When the guide needle 3990 of the arranging mechanism 3 has finished winding the wire on the clamp 64, the clamping and throwing cylinder 790 in the wire pulling mechanism 7 can pull the wire end of the wire material to reset and retreat under the drive of the wire pulling cylinder 76 to break the wire end on the clamp 64. When the wire arranging mechanism 3 winds the wire, the clamping and throwing cylinder 790 in the wire pulling mechanism 7 can rotate through the throwing rotation shaft 78 and under the drive of the throwing rotation angle power cylinder 77, so that the clamping and throwing cylinder 790 can realize the sideways rotation of the wire end broken before winding and throw the wire end to the preset waste recycling place, so as to realize the waste recycling of the discarded wire end.

[0075] When the winding spindle 8 equipped with the clamp 64 in the winding mechanism 2 rotates under the drive of the winding motor 9 connected thereto, it can drive the coil in the clamp 64 to automatically wind. At the same time, the wire arranging mechanism 3 cooperates with the winding mechanism 2 to arrange the wire on the skeleton on the winding spindle 8, so as to realize the wire arranging and winding of the skeleton.

[0076] When the winding mechanism 2 has finished winding the wire on the frame, the guide pin 3990 in the wire arrangement mechanism 3 can lead the wire from the frame to the clamp 64 under the joint drive of the wire arrangement X-axis motor 37, the wire arrangement Y-axis motor 33 and the wire arrangement Z-axis motor 39. Then, the guide pin 3990 makes a circular motion on the clamp 64 on the winding spindle 8 under the joint drive of the wire arrangement X-axis motor 37, the wire arrangement Y-axis motor 33 and the wire arrangement Z-axis motor 39 to achieve winding the wire on the clamp 64. Then, the wire clamping and throwing cylinder 790 in the wire pulling mechanism 7 moves forward under the drive of the wire pulling cylinder 76 to prepare for cutting the wire after winding.

[0077] When the middle guide needle 3990 of the wire arranging mechanism 3 moves toward the direction of the wire pulling mechanism 7 under the joint drive of the wire arranging X-axis motor 37, the wire arranging Y-axis motor 33 and the wire arranging Z-axis motor 39, the wire can be led through the wire clamping and wire throwing cylinder 790; and the wire clamping and wire throwing cylinder 790 in the wire pulling mechanism 7 can clamp the wire during the closing process, and when the wire clamping and wire throwing cylinder 790 is completely closed, the wire can be cut to complete the winding of the clamp 64.

[0078] Since when one of the winding spindles 8 of the winding mechanism 2 is in the winding state, the fixture loading and unloading manipulator 5 can clamp the next fixture 64 to be wound from the fixture feeding mechanism 6, and install the next fixture 64 to be wound on the other winding spindle 8 in the winding mechanism 2 rotated to the side of the fixture unloading mechanism 4, it enables the double-station winding spindle 8 in the winding mechanism 2 to rotate and work uninterruptedly to improve the winding efficiency. When the skeleton in the previous fixture 64 is completed to be wound into a coil, the winding transposition spindle 27 in the winding mechanism 2 can switch the positions of the two winding spindles 8 when it rotates again under the drive of the winding transposition motor 13, so that the fixture 64 that has completed the winding can be rotated to one side of the fixture unloading mechanism 4, and the fixture 64 to be wound installed on the next side is rotated to the side of the wire arrangement mechanism 3 to start a new round of wire arrangement and winding operation. Next, the glue gun 4993 in the fixture unloading mechanism 4 can be moved to the coil of the fixture 64 that has completed winding in the winding spindle 8 under the joint drive of the fixture unloading X-axis motor 49 and the fixture unloading Y-axis motor 44. Then, the glue gun 4993 in the fixture unloading mechanism 4 can glue the coil on the fixture 64 that has completed winding as it moves downward along with the glue dispensing slide 4990 and under the pull of the glue dispensing cylinder 4992; then, the hot air gun 498 can be moved to the top of the coil that has completed glue dispensing under the joint drive of the fixture unloading X-axis motor 49 and the fixture unloading Y-axis motor 44, and when the hot air gun 498 is started, the surface of the coil that has completed glue dispensing can be dried with hot air. When the glue on the surface of the coil is dried by hot air, the unloading plate fork 497, under the joint drive of the fixture unloading X-axis motor 49 and the fixture unloading Y-axis motor 44, first presses the fixture unloading sleeve 82 in the winding spindle 8 that has completed the winding, and then resets. After being pressed by the fixture unloading sleeve 82, the marble 85 can bounce out of the circular groove of the fixture and exit the inner wall of the fixture sleeve 84 by the rebound force, so that the winding spindle 8 can loosen the clamping of the fixture 64, so as to facilitate the fixture loading and unloading robot 5 to take away the coil that has completed the hot air drying, and put it The coil is placed at the position of the last fixture 64 that was taken away in the feeding jig 63 of the fixture feeding mechanism 6. At the same time, the fixture loading and unloading robot 5 clamps the next adjacent fixture 64 to be wound from the feeding jig 63 of the fixture feeding mechanism 6, and installs it on the winding spindle 8 that lacks the fixture 64. At this time, the unloading plate fork 497 in the fixture unloading mechanism 4 presses the fixture unloading sleeve 82 in the winding spindle 8 according to the aforementioned method, so that the fixture 64 can be firmly installed on the winding spindle 8, and the cycle is repeated.The coil wound by the method has the advantages of smooth winding, tight winding, good winding effect, high winding efficiency, high product yield, low production cost and ability to prevent coil frame deformation. The method not only effectively solves the problem that the winding equipment with the current structure has the problem of uneven winding, loose winding, poor winding effect, low product yield and high product production cost due to the inability to firmly install the winding spindle and the clamp, but also solves the problem that the accelerometer sensor coil is prone to frame deformation during the winding process and when assembling and disassembling the frame due to the fine wire material, small coil frame and low frame rigidity.
