Description

Technical Field

[0001] The invention relates to the technical field of micro coil winding, in particular to a digitally controlled micro coil winding machine. Background Art

[0002] Micro solenoid valves are widely used in functional control systems of precision structures in industries such as aerospace, medical equipment, and vehicle engineering. Among them, micro solenoid coils are the core components of micro solenoid valves, which directly determine the working stability and reliability of solenoid valves. At present, the degree of automation of the winding process of most solenoid valve coils is not high, and the large amount of human intervention leads to low work efficiency and low product qualification rate. The existing coil winding machines use single motor rotation or synchronous belt drive, and there are problems such as far-end jitter during the high-speed winding process of the cantilever structure or torsional deformation caused by the speed difference at both ends of the mandrel, which affects the coil winding quality. Secondly, the mandrel clamping mainly relies on the manual debugging of the workers. The clamping process is time-consuming, and the clamping structure cannot guarantee the clamping positioning accuracy and consistency of the mandrel, which easily leads to winding failure and low product qualification rate.

[0040] like Figure 1 As shown: the hot air gun assembly 4 is placed in front of the spindle assembly 2. When winding, the hot air gun assembly 4 continuously blows hot air to melt the solid glue on the surface of the wound wire, so that adjacent coils are bonded to each other to ensure the wiring effect. The start and stop and air volume of the hot air gun assembly 4 can be controlled by the controller.

[0041] like Figure 6 As shown: the machine base assembly 1 is composed of a spindle component mounting plate 28, a back plate 40, a left vertical plate 42, and a right vertical plate 29; a spindle component mounting plate 28 is placed at the lower right corner of the machine base assembly 1 for mounting the spindle assembly 2, and a back plate 40 is placed on the rear side of the machine base assembly 1; the left vertical plate 42 and the right vertical plate 29 are placed parallel to the back plate 40; a square through hole is left on the left vertical plate 42, and a boss 36 for mounting a guide rail 38 is placed between the left vertical plate 42 and the right vertical plate 29, and the left vertical plate 42 and the right vertical plate 29 are perpendicular to the bottom surface and the side plate 48 of the machine base assembly 1.

[0042] Figure 2 The three-dimensional structure diagram of the spindle assembly 2 is shown in FIG. Figure 3 This is the parts assembly drawing of the main spindle assembly 2, which consists of a lifting platform 3, a core rod bracket 12, a limit plate 13, a clamp fixing frame 14, a push plate 15, a clamp 16, a right motor assembly 5, and a left motor assembly 8; the main spindle assembly 2 is fixed to the main spindle component mounting plate 28 of the base assembly 1 by bolts, and circular through holes are left on both sides of the main spindle assembly 2, which are used to install the left motor assembly 8 and the right motor assembly 5 respectively.

[0043] like Figure 3 As shown: the left motor assembly 8 is fixed to the left side of the spindle assembly 2 through a fixed sleeve 25, and the left motor assembly 8 includes a left servo motor 26, and the output shaft of the left servo motor 26 is concentric with the left through hole of the spindle assembly 2; the right motor assembly 5 is installed on the right side of the spindle assembly 2 through a movable sleeve 18, and the right motor assembly 5 includes a right servo motor 17, and the output shaft of the right servo motor 17 is concentric with the right through hole of the spindle assembly 2; the movable sleeve 25 can move left and right on the spindle assembly 2 along its axis;

[0044] The clamp 16 is used to control the left and right movement of the right motor assembly 5 on the spindle assembly 2. Moving to the left corresponds to clamping the workpiece, and moving to the right corresponds to loosening the workpiece. The clamp fixing frame 14 is fixed to the lower right part of the spindle assembly 2 by screws. The clamp 16 is installed on the clamp fixing frame 14. The push plate 15 is fixed to the front end of the clamp 16 by screws.

[0045] The spring 19 is mounted on the movable sleeve 18, and its function is to apply axial tension to the clamped mandrel 59 to keep it in a straight state, so as to prevent the mandrel 59 from bending due to the winding force during the rotation process, thereby affecting the winding processing quality.

[0046] The left servo motor 26 and the right servo motor 17 are controlled by a controller to rotate synchronously to avoid torsional deformation of the core rod 59 due to the speed difference.

[0047] Figure 4 It is a structural schematic diagram of the left centering clamp and the right centering clamp. The right centering clamp 20 is fixed to the output shaft of the right servo motor 17 by a set screw, and the right centering clamp 20 has a right centering external rotation 22 threadedly installed on the external thread; the left centering clamp 24 is fixed to the output shaft of the left servo motor 26 by a set screw, and the left centering external rotation 23 is threadedly installed on the external thread of the left centering clamp 24; the conical parts of the left centering clamp 24 and the right centering clamp 20 are provided with grooves 24a; the left centering clamp 24 and the right centering clamp 20 have holes 24b at the right axis, and the right end near the center part has a waist hole 24c; the middle part of the left centering clamp 24 and the right centering clamp 20 is provided with external threads,

[0048] The centering clamp hole 24b can ensure the positioning of the core rod. At the same time, only one groove 24a is opened to prevent the wire to be wound from being stuck in the centering clamp groove 24a during the winding process, thereby improving the product qualification rate; the waist hole 24c ensures that the deformation of the centering clamp 24 is close to the thread end when clamping the workpiece, thereby ensuring that the groove 24a is closed in parallel to prevent the workpiece from being clamped.

[0049] like Figure 3 As shown: the lifting platform 3 is fixed to the boss at the center of the spindle assembly 2 by screws, and a semicircular groove is left at the upper end of the mandrel bracket 12 to carry the mandrel 59; the mandrel bracket 12 is fixed to the upper surface of the lifting platform 3 by screws, and a mandrel shifting plate 73 is fixed to the side of the mandrel bracket 12 by a stop pin; when working, by rotating the knob of the lifting platform 3, the lifting platform 3 slowly rises with the mandrel bracket 12 for clamping the mandrel 59.

[0050] like Figure 5 As shown: the mandrel bracket 12 moves only in the y direction, the mandrel 59 is parallel to the x axis, and the entire working surface is located in the xoy plane. The left servo motor 26 is controlled to ensure that the groove 24a of the left centering clamp 23 coincides with the xoy plane. The mandrel bracket 12 moves along the y direction, and the left end portion enters the groove 24a until the axis of the mandrel 59 coincides with the axis of the hole 24b. Rotate the left centering external rotation 23, the groove 24a is completely closed, and the positioning and clamping of the mandrel is completed. The above process is easy to operate and greatly improves the clamping efficiency of the mandrel 59; the limit plate 13 records the moving distance of the mandrel 59, one end of which is placed on the mandrel bracket 12, and the other end is fixed to the right inner side of the spindle assembly 2 by screws. The limit plate 13 is used to limit the moving distance of the lifting platform 3 in the y direction to ensure that the mandrel 59 can be accurately clamped in the center; the mandrel moving plate 73 is used to limit the movement of the mandrel 59 in the x direction to ensure the clamping end length and the extended end length of the mandrel 59 in the centering clamp 23;

[0053] The controller controls the servo motor 39 to rotate forward and reverse, driving the vertical guide shaft support 37 to move left and right, thereby driving the wire arranging device 31 to move left and right to complete the multi-layer winding. The programmable logic controller is used to control the servo motor 39 to realize the multi-segment motion characteristics of the wire arranging frame during the winding process of each layer of coils, which can avoid the acceleration shock generated when the wire arranging frame reciprocates. The wire arranging device 31 provides tension during the winding process.

[0054] like Figure 7 As shown: the electrical box assembly 58 consists of a side panel 48, a control panel 11, a start / stop button 43, an emergency stop button 44, a front cover plate 45, a cover plate 9, a right side panel 10, a right front cover plate 46, and an electrical cabinet 47; the side panel 10 is fixed to the left side of the electrical box assembly 58 by screws; the front cover plate 45 is fixed to the front of the electrical box assembly 58 by screws, with a square hole in the middle and three round holes below the square hole; the control panel 11 is mounted on the square hole of the front cover plate 45; the start / stop button 43 and the emergency stop button 44 are mounted on the round holes of the front cover plate 45; the right side panel 10 is mounted on the right side of the electrical box assembly 58 by screws; the right front cover plate 46 is fixed to the left vertical plate 42 and the right vertical plate 29 by screws; the electrical cabinet 47 is installed inside the electrical box assembly 58 to carry the electrical components of the control system; the cover plate 9 is fixed to the upper surface of the electrical box assembly 58 by screws.

[0055] Specifically, the control panel 11 controls the synchronous movement of the left servo motor assembly 26, the right servo motor 17, and the cable servo motor, and can also adjust the number of winding layers, winding speed, and hot air volume;

[0056] As shown in 8: the camera assembly 7 is composed of a base plate 51, a column 50, a first same-diameter cross fixing clamp 49, a monitoring screen 52, a cross bar 53, an inclined bar 54, a third same-diameter cross fixing clamp 55, a second same-diameter cross fixing clamp 57, and a camera 56; the base plate 51 is used to support the remaining components of the upper camera assembly 7; the column 50 is fixed on the base plate 51, perpendicular to the base plate 50; the first same-diameter cross fixing clamp 49 is installed on the column 50 by bolts; the monitoring screen 52 is fixed on the column 50; the cross bar 53 passes through the first same-diameter cross fixing clamp 49, and is perpendicular to the column 50; the second same-diameter cross fixing clamp 57 is fixed to the left side of the cross bar 53 by bolts; one end of the inclined bar 54 is fixed to the second same-diameter cross fixing clamp 57, and the other end is connected to the third same-diameter cross fixing clamp 55; the camera 56 is fixed to the third same-diameter cross fixing clamp 55 by screws;
