[0004] Although the aforementioned patent document achieves streamlined operation, it is essentially a streamlined assembly equipment. For example, it uses a coil implantation mold device to load and assemble the wound coils, but it does not have the function of direct coil winding and glue dispensing. Furthermore, the layout is unreasonable and occupies a large amount of space in the work area. Summary of the Invention

[0005] The purpose of this invention is to provide an integrated inductor coil winding and dispensing machine. This machine realizes the assembly line operation of inductor production, and can produce complete inductor devices in one machine. It is not only highly efficient, but also has a compact structure and occupies little space.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by the present invention is as follows: An integrated inductor coil winding and dispensing machine includes a worktable, on which are provided an intermittent turntable for winding and an intermittent turntable for dispensing. Magnetic core fixtures are distributed around the periphery of the intermittent turntable for winding. On the worktable and around the intermittent turntable for winding, a magnetic core feeding device, a coil winding and cutting device, a coil end gathering and positioning device, a winding end excess length cutting device, a wire end welding device, a coil detection device, and a coil transfer device are arranged in sequence.The dispensing intermittent turntable has dispensing fixtures distributed around its periphery. On the worktable, surrounding the dispensing intermittent turntable, are sequentially arranged a first dispensing device, a coil flipping device, a second dispensing device, a scraping device, a dispensing detection device, and an inductor coil removal device. The magnetic core feeding device moves the magnetic core into the magnetic core fixture. The winding intermittent turntable rotates the magnetic core in the fixture to the coil winding and cutting station. The coil winding and cutting device winds the wire onto the magnetic core and cuts the coil ends. The winding intermittent turntable rotates the coiled magnetic core to the winding end gathering station. The coil end gathering and positioning device gathers and positions the two ends of the coil to the same end of the magnetic core. On the surface, an intermittent turntable rotates the magnetic core with the coil wound to the wire end trimming station. The wire end trimming device trims off the excess length of the two ends of the coil on the magnetic core. The intermittent turntable then rotates the magnetic core with the coil wound to the welding station. The wire end welding device welds the two ends of the coil to the same end face of the magnetic core. The intermittent turntable then rotates the magnetic core with the coil wound to the inspection station. The coil inspection device inspects the magnetic core with the coil wound. The intermittent turntable then rotates the magnetic core with the coil wound to the transfer station. The coil transfer device processes the magnetic core with the coil wound according to the inspection results, moving any cores with coil wound that fail the inspection to an unqualified transfer station. In the qualified product collection box, qualified magnetic cores with coils are transferred to the dispensing fixture on an intermittent dispensing turntable. The intermittent dispensing turntable rotates the magnetic core with coils to the first dispensing station, where the first dispensing device drips glue onto the upper surface of the coil. The intermittent dispensing turntable then rotates the magnetic core with coils to the flipping station, where the coil flipping device rotates the dispensing fixture 180° so that the lower surface of the coil faces upward. The intermittent dispensing turntable then rotates the magnetic core with coils to the second dispensing station, where the second dispensing device drips glue onto the surface of the coil. Finally, the intermittent dispensing turntable rotates the magnetic core with coils to the scraping station, where the scraping device scrapes glue onto the surface of the coil. The adhesive is evenly spread onto the surface of the coil. An intermittent turntable rotates the coated coil to a testing station. A testing device inspects the coil. The tested coil is then rotated to a removal station. Based on the test results, the inductor coil removal device processes the coils, moving defective coils to a defective product collection box and transferring qualified coils to an inductor coil conveyor belt. This conveyor belt feeds the coils onto the upper conveyor belt in the curing chamber. The coils on the upper conveyor belt fall onto the lower conveyor belt in the curing chamber, which then removes the finished inductor coils from the curing chamber into a finished product box.

[0007] Furthermore, the curing chamber is located on one side of the workbench.

[0008] Furthermore, the workbench has a notch on its surface, and the defective product collection box is located below the notch.

[0009] Furthermore, the winding intermittent turntable is provided with wire clamps on both sides of the magnetic core fixture, the wire clamps being used to clamp and fix the winding.

[0010] Furthermore, the wire clamp includes a Y-shaped frame and two wire pressing assemblies. The two wire pressing assemblies are located at the ends of two branch plates on the Y-shaped frame. Each wire pressing assembly includes a fixed post, a fixed plate, a limiting post, a compression spring, a pressure cylinder, and a limiting guide rod. The fixed post is fixed on the Y-shaped frame, the fixed plate is horizontally fixed on the upper end of the fixed post, the limiting post is vertically fixed on the fixed plate, the compression spring is located inside the pressure cylinder and is fitted onto the limiting post, the upper end of the compression spring presses against the fixed plate, and the lower end of the compression spring presses against the bottom surface of the cylinder inside the pressure cylinder. The upper end of the limiting guide rod is fixedly connected to the bottom surface of the cylinder outside the pressure cylinder, and the lower end of the limiting guide rod passes downward through the vertical guide sleeve on the Y-shaped frame.

[0011] Furthermore, a lifting cylinder is provided below the Y-shaped frame. The lifting cylinder is used to lift the limiting guide rod upward. The limiting guide rod pushes the pressure cylinder upward. When the winding is below the pressure cylinder, the lifting cylinder resets. Under the action of the pressure spring, the pressure cylinder presses the winding tightly onto the Y-shaped frame.

[0012] Furthermore, the coil winding and cutting device includes a winding motor and a moving mechanism. The output shaft of the winding motor is a hollow shaft that passes through the housing of the winding motor. A winding tube is provided at an eccentric position on the end face of the hollow shaft. The winding wire on the winding disc passes through the hollow shaft and the winding tube in sequence via a guide wheel. The winding motor is fixed on the moving mechanism. The winding motor drives the winding tube to rotate around the magnetic core through the hollow shaft, winding the wire onto the magnetic core. At the same time, the moving motor drives the moving mechanism to move, and the moving mechanism drives the winding motor, which in turn drives the winding tube to move.

[0013] Furthermore, the moving mechanism is also equipped with cutting shears and a cylinder, and the cylinder drives the cutting shears to perform cutting actions.

[0014] Furthermore, the coil flipping device includes a transmission mechanism, a clutch shaft, a flipping drive motor, and a linear motion device. The transmission mechanism is located inside the intermittent dispensing turntable. The clutch shaft is mounted on the intermittent dispensing turntable, with its clutch end extending horizontally outside the turntable. The flipping drive motor is mounted on the linear motion device and located outside the intermittent dispensing turntable. The linear motion device drives the flipping drive motor to move, causing the end of the output shaft of the flipping drive motor to insert into the clutch end of the clutch shaft. The flipping drive motor drives the clutch shaft, and the clutch shaft drives the dispensing fixture to rotate 180° through the transmission mechanism.

[0015] Furthermore, the coil end-gathering and positioning device includes a transverse drive motor, a transverse slide rail, a transverse slide block, a lifting drive motor, a vertical slide rail, a lifting slide block, a pressing cylinder, a gathering assembly, a support frame, and a wire pressing and positioning mechanism. The gathering assembly includes a rear gathering cylinder, a rear rotating sleeve, a rear gathering swing rod, a rear return spring, a front gathering cylinder, a front rotating sleeve, a front gathering swing rod, a front return spring, and a pressure plate. The rear gathering swing rod and the front gathering swing rod are respectively fixed on the rear rotating sleeve and the front rotating sleeve and are parallel to each other. The rear rotating sleeve and the front rotating sleeve are respectively mounted on the piston rod ends of the rear retracting cylinder and the front retracting cylinder via bearings. The rear retracting cylinder and the front retracting cylinder are fixed on the lifting slide block. The lifting slide block is located on a vertical slide rail, which is located on the side wall of the transverse slide block. The transverse slide block is located on a horizontal slide rail. The transverse drive motor drives the transverse slide block to move left and right along the horizontal slide rail. The lifting drive motor drives the lifting slide block to move up and down along the vertical slide rail. The pressing cylinder drives the pressure plate. The pressure plate presses down, causing the left ends of the rear and front retracting swing arms to tilt upwards, thus gathering the two wire ends of the coil above the magnetic core. The rear and front return springs are used to move the left ends of the rear and front retracting swing arms upwards and reset them. The rear and front retracting cylinders drive the rear and front retracting swing arms to move towards each other, gathering the two wire ends of the coil to the top of the magnetic core. The wire positioning mechanism is used to position the coil at the top of the magnetic core. The two ends of the wire are pressed tightly against the end face of the magnetic core; the wire pressing and positioning mechanism includes a wire pressing drive motor, a vertical slide rail, a wire pressing slide block, and a wire pressing rod. The wire pressing rod is vertically installed on the wire pressing slide block, the wire pressing slide block is installed on the vertical slide rail, the vertical slide rail is set on a support frame, and the support frame is connected to a fixed column in the center hole of the winding intermittent turntable. Under the power of the wire pressing drive motor, the wire pressing rod moves downward, and the lower end of the wire pressing rod presses the two ends of the coil at the top of the magnetic core tightly against the end face of the magnetic core.

[0016] The beneficial effects of this invention are as follows: This application concentrates coil winding and coil surface dispensing and encapsulation on a single workbench and arranges the curing chamber on one side of the workbench, thereby realizing a production line operation for inductor production. A complete inductor device can be manufactured in one machine, which not only has high work efficiency, but also has a compact structure and occupies little space. Attached Figure Description

[0021] like Figure 1 , 2As shown in Figure 3, an integrated inductor coil winding and dispensing machine includes a worktable 1. The worktable 1 has an intermittent turntable 2 for winding and an intermittent turntable 3 for dispensing. Magnetic core fixtures 4 are distributed around the periphery of the intermittent turntable 2. On the worktable 1 and around the intermittent turntable 2, a magnetic core feeding device 5, a coil winding and cutting device 6, a coil end gathering and positioning device 7, a winding end excess length cutting device 8, a wire end welding device 9, a coil detection device 10, and a coil transfer device 11 are arranged in sequence. Dispensing fixtures 12 are distributed around the periphery of the intermittent turntable 3. On the worktable 1 and around the intermittent turntable 3, a first dispensing device 13, a coil flipping device 14, and a second dispensing device 15 are arranged in sequence. The system includes a secondary dispensing device 15, a scraping device 16, a dispensing detection device 17, and an inductor coil removal device 18. The magnetic core feeding device 5 moves the magnetic core 19 into the magnetic core fixture 4. An intermittent winding turntable 2 rotates the magnetic core in the fixture to the coil winding and cutting station. The coil winding and cutting device 6 winds the winding wire 20 onto the magnetic core 19 and cuts off the coil ends. The intermittent winding turntable 2 rotates the wound magnetic core to the winding end gathering station. The coil end gathering and positioning device 7 gathers and positions the two ends of the coil onto the same end face of the magnetic core 19. The intermittent winding turntable 2 rotates the wound magnetic core to the wire end excess length cutting station. The winding end excess length cutting device cuts off the excess length of the coil on the magnetic core 8. The excess length of the wire ends is trimmed off. The intermittent turntable 2 rotates the coiled magnetic core to the soldering station. The wire end soldering device 9 solders the two wire ends 50 of the coil 49 to the same end face 51 of the magnetic core 19. After soldering, two raised solder lines 52 are formed on the same end face 51 of the magnetic core 19. The intermittent turntable 2 rotates the coiled magnetic core to the inspection station. The coil inspection device 10 inspects the coiled magnetic core. The intermittent turntable 2 rotates the coiled magnetic core to the transfer station. The coil transfer device 11 processes the coiled magnetic cores according to the inspection results, moving unqualified coiled magnetic cores into the unqualified product collection box 21, and transferring qualified coiled magnetic cores... The magnetic core is transferred to the dispensing fixture 12 on the intermittent dispensing turntable 3. The intermittent dispensing turntable 3 rotates the magnetic core with the coil wound around it to the first dispensing station. The first dispensing device 13 drips glue onto the upper surface of the coil. The intermittent dispensing turntable 3 rotates the magnetic core with the coil wound around it to the flipping station. The coil flipping device 14 rotates the dispensing fixture 12 180° so that the lower surface of the coil faces upward. The intermittent dispensing turntable 3 rotates the magnetic core with the coil wound around it to the second dispensing station. The second dispensing device 15 drips glue onto the surface of the coil. The intermittent dispensing turntable 3 rotates the magnetic core with the coil wound around it to the scraping station. The scraping device 16 scrapes the glue onto the surface of the coil, spreading the glue evenly on the surface of the coil.The intermittent dispensing turntable 3 rotates the coated coil to the inspection station. The dispensing inspection device 17 inspects the coil. The intermittent dispensing turntable 3 then rotates the inspected coil to the removal station. The inductor coil removal device 18 processes the inductor coils according to the inspection results. Inductor coils that fail the inspection are moved to the defective product collection box 21, while qualified inductor coils are transferred to the inductor coil conveyor belt 22. The inductor coil conveyor belt 22 feeds the inductor coils onto the upper conveyor belt in the curing chamber 23. The inductor coils on the upper conveyor belt in the curing chamber 23 fall downwards onto the lower conveyor belt in the curing chamber. The lower conveyor belt removes the finished inductor coils from the curing chamber 23 into the finished product box 24.

[0022] The curing chamber 23 is located on one side of the workbench 1. The workbench 1 has a notch 25 on its surface, and the defective product collection box 21 is located below the notch 25.

[0023] Wire clamps 26 are provided on the intermittent turntable 2 for winding and on both sides of the magnetic core fixture 4. The wire clamps 26 are used to clamp and fix the winding.

[0024] It should be noted that this application improves the coil winding and cutting device 6, the coil two-wire end gathering and positioning device 7, the coil flipping device 14, and the wire clamp 26. However, the magnetic core feeding device 5, the wire end welding device 9, the coil detection device 10, the coil transfer device 11, the first glue dispensing device 13, the second glue dispensing device 15, the glue dispensing detection device 17, and the inductor coil removal device 18 adopt existing technology.

[0025] like Figure 4 , 5 As shown, the wire clamp 26 includes a Y-shaped frame 27 and two wire pressing assemblies 28. The two wire pressing assemblies 28 are located at the ends of two branch plates on the Y-shaped frame 27. Each wire pressing assembly 28 includes a fixing post 29, a fixing plate 30, a limiting post 31, a compression spring 32, a pressing cylinder 33, and a limiting guide rod 34. The fixing post 29 is fixed on the Y-shaped frame 27. The fixing plate 30 is horizontally fixed on the upper end of the fixing post 29. The limiting post 31 is vertically fixed on the lower surface of the fixing plate 30. The compression spring 32 is located inside the pressing cylinder 33 and is fitted onto the limiting post 31. The upper end of the compression spring 32 presses against the fixing plate 30, and the lower end of the compression spring 32 presses against the bottom surface of the cylinder inside the pressing cylinder 33. The upper end of the limiting guide rod 34 is fixedly connected to the bottom surface of the cylinder outside the pressing cylinder 33, and the lower end of the limiting guide rod 34 passes downward through the vertical guide sleeve 35 on the Y-shaped frame 27. A lifting cylinder 36 is provided below the Y-shaped frame 27. The lifting cylinder 36 is used to lift the limiting guide rod 34 upward. The limiting guide rod 34 pushes the pressure cylinder 33 upward. When the winding is below the pressure cylinder 33, the lifting cylinder 36 resets. Under the action of the pressure spring 32, the pressure cylinder 33 presses the winding tightly onto the Y-shaped frame 27.

[0026] As the intermittent turntable 2 rotates, the coil winding and cutting device 6 moves toward the magnetic core. The winding on the coil winding and cutting device 6 gradually moves toward the wire pressing assembly 28. When the lifting cylinder 36 lifts the pressing cylinder 33, the winding just enters below the pressing cylinder 33. When the pressing cylinder 33 presses down on the winding, the coil winding action and the cutting action of the coil winding and cutting device 6 start simultaneously. The cutting point is located on the winding segment on the wire clamp 26 between the completed coil and the coil that has started to be wound.

[0027] like Figure 6 , 7 As shown, the coil winding and cutting device 6 includes a winding motor 37 and a moving mechanism 38. The output shaft of the winding motor 37 is a hollow shaft 39, which passes through the housing of the winding motor 37. A winding tube 40 is provided at an eccentric position on the end face of the hollow shaft 39. The winding 20 on the winding disc 41 passes through the hollow shaft 39 and the winding tube 40 in sequence via the guide wheel 42. The winding motor 37 is fixed on the moving mechanism 38. The winding motor 37 drives the winding tube 40 to rotate around the magnetic core 19 through the hollow shaft 39, winding the winding 20 onto the magnetic core 19. At the same time, the moving motor 43 drives the moving mechanism 38 to move, and the moving mechanism 38 drives the winding motor 37, which in turn drives the winding tube 40 to move. The moving mechanism 38 is also provided with a cutting shear 44 and a cylinder 45. The cylinder 45 drives the cutting shear 44 to perform a cutting action to cut the winding between the two wire pressing assemblies 28.

[0028] This application also improves the coil flipping device 14, such as... Figure 8 As shown, the coil flipping device 14 includes a transmission mechanism, a clutch shaft 46, a flipping drive motor 47, and a linear movement device 48. The transmission mechanism is located inside the intermittent dispensing turntable 3. The clutch shaft 46 is mounted on the intermittent dispensing turntable 3, with the clutch end of the clutch shaft 46 extending horizontally outside the intermittent dispensing turntable 3. The flipping drive motor 47 is mounted on the linear movement device 48 and located outside the intermittent dispensing turntable 3. The linear movement device 48 drives the flipping drive motor 47 to move linearly, so that the end of the output shaft of the flipping drive motor 47 is inserted into the clutch end of the clutch shaft 46. The flipping drive motor 47 drives the clutch shaft 46, and the clutch shaft 46 drives the dispensing fixture 12 to rotate 180° through the transmission mechanism. The transmission mechanism in the coil flipping device 14 includes a passive shaft installed inside the intermittent dispensing turntable 3. One end of the passive shaft extends horizontally outside the intermittent dispensing turntable 3 and is connected to the dispensing fixture 12. That is, the dispensing fixture 12 is installed at the end of the passive shaft. The gear on the passive shaft meshes with the gear on the clutch shaft 46. One end of the clutch shaft 46 also extends horizontally outside the intermittent dispensing turntable 3. The transmission mechanism is inside the intermittent dispensing turntable 3, which is not shown in the figure.

[0029] In addition to its flipping function, the coil flipping device 14 also assists in applying adhesive. Specifically, the adhesive application device 16 uses a scraper plate mounted on a lifting mechanism. A scraper motor drives the lifting mechanism, lowering the scraper plate above the coil on the magnetic core. The coil flipping device 14 then rotates the dispensing fixture 12, causing the magnetic core to rotate. The scraper plate then applies adhesive to the coil surface, ensuring the adhesive is evenly spread. The lifting mechanism uses a lead screw and slider module structure.

[0030] The coil flipping device of this application has the following features: it ingeniously separates the power unit and the transmission mechanism. The dispensing fixture and the transmission mechanism are mounted on the dispensing intermittent turntable 3, while the power unit is located outside the dispensing intermittent turntable 3. When flipping, there is no need to move the magnetic core and coil. The flipping can be achieved directly on the dispensing fixture, which not only simplifies the process, but also requires only one power unit to achieve the flipping of each dispensing fixture.

[0031] like Figure 9 , 10As shown in Figure 11, the coil two-wire end gathering and positioning device 7 includes a transverse drive motor 52, a transverse slide rail 53, a transverse slide block 54, a lifting drive motor 55, a vertical slide rail 56, a lifting slide block 57, a pressing cylinder 58, a gathering assembly 59, a support frame 60, and a wire pressing and positioning mechanism 61. The gathering assembly 59 includes a rear gathering cylinder 66, a rear rotating sleeve 67, a rear gathering swing rod 68, a rear return spring 69, a front gathering cylinder 70, a front rotating sleeve 71, a front gathering swing rod 72, a front return spring 73, and a pressure plate 74. The rear gathering swing rod 68 and the front gathering swing rod 72 are respectively fixed on the rear rotating sleeve 67 and the front rotating sleeve 71 and are parallel to each other. 67 and the front rotating sleeve 71 are respectively mounted on the piston rod ends of the rear retracting cylinder 66 and the front retracting cylinder 70 via bearings. The rear retracting cylinder 66 and the front retracting cylinder 70 are fixed on the lifting slide 57. The lifting slide 57 is provided on the vertical slide rail 56, which is provided on the side wall of the transverse slide 54. The transverse slide 54 is provided on the horizontal slide rail 53. The transverse drive motor 52 drives the transverse slide 54 to move left and right along the horizontal slide rail 53. The lifting drive motor 55 drives the lifting slide 57 to rise and fall along the vertical slide rail 56. The pressing cylinder 58 is installed on the lifting slide 57 and drives the pressure plate. 74 moves down, and after the pressure plate 74 presses down, the left ends of the rear retracting swing arm 68 and the front retracting swing arm 72 are retracted, causing the right ends of the rear retracting swing arm 68 and the front retracting swing arm 72 to tilt upwards, so as to retract the two wire ends 50 of the coil 49 to the top of the magnetic core 19. The rear return spring 69 and the front return spring 73 are respectively used to move the left ends of the rear retracting swing arm 68 and the front retracting swing arm 72 upwards to reset. The rear retracting cylinder 66 and the front retracting cylinder 70 respectively drive the rear retracting swing arm 68 and the front retracting swing arm 72 to move towards each other, retracting the two wire ends 50 of the coil 49 to the top or directly above the magnetic core 19. The wire positioning mechanism 61 is used to position the two wire ends of the coil at the top of the magnetic core. The wire pressing mechanism includes a wire pressing drive motor 62, a vertical slide rail 63, a wire pressing slide 64, and a wire pressing rod 65. The wire pressing rod 65 is vertically mounted on the wire pressing slide 64, and the wire pressing slide 64 is mounted on the vertical slide rail 63. The vertical slide rail 63 is located on a support frame 60, and the support frame 60 is connected to a fixed column in the center hole of the winding intermittent turntable 2. Under the power of the wire pressing drive motor 62, the wire pressing slide 64 moves along the vertical slide rail 63, driving the wire pressing rod 65 to move downward. The lower end of the wire pressing rod 65 presses the two wire ends 50 of the coil 49 at the top of the magnetic core 19 tightly onto the end face 51 of the magnetic core 19.

[0032] Before being gathered, the two ends of the coil are pressed onto the wire clamps 26 on both sides of the magnetic core fixture 4. The rear gathering lever 68 and the front gathering lever 72 in the two-end gathering and positioning device 7 lift the two ends of the coil upwards, causing them to detach from the wire clamps 26. Then, the rear gathering lever 68 and the front gathering lever 72 move closer together, gathering the two ends of the coil to the top or directly above the magnetic core 19. Finally, they are positioned by the wire pressing and positioning mechanism 61, preparing for the cutting of excess wire length in the next process. The coil two-end gathering and positioning device 7 replaces manual operation, greatly improving the automation level of the machine.
