[0002] Inductor coils are widely used in a variety of electrical components. In the manufacturing process, inductor coils need to go through multiple processes. Usually, the coil is first wound on the coil frame, and then the wound coil frame is loaded into the coil disk for the next process. The coil winding is completed on the winding machine. In order to improve the winding efficiency, multiple coil frames are usually arranged at the winding station for winding at the same time. To ensure the winding quality of the coil, each coil frame needs to maintain a certain distance. After the winding is completed, the coil frame is transferred to the coil disk for the next process. However, the spacing between the coil posts on the coil disk is small, which does not match the spacing between the coil posts on the winding station. Automatic unloading and loading cannot be achieved. The coil frames need to be manually removed from the winding station and then arranged one by one on the coil posts of the coil disk, resulting in low production efficiency of electrical components and high labor costs.

DETAILED DESCRIPTION

[0024] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings:

[0025] See also Figure 1-6 The present embodiment discloses a variable-distance blanking and loading machine, which includes a variable-distance blanking mechanism and a material picking and loading mechanism. The variable-distance blanking mechanism includes a blanking device, a variable-distance device and a loading platform. The material picking and loading mechanism includes a picking device and a loading device. The blanking device is used to remove the coil frame 50 after winding is completed from the winding station 81, and the variable-distance device is used to change the spacing of the loading platform so that the spacing between the clamping grooves 15 can respectively adapt to the spacing of the coil frame 50 on the winding station 81 and the spacing of the coil frame 50 on the coil disk 71; the picking device is used to remove the coil frame 50 located in the clamping groove 15, transfer it to the top of the coil disk 71, and cooperate with the loading device to arrange the coil frame 50 that has completed winding on the coil column 72 of the coil disk 71; the variable-distance blanking and loading machine also includes a control system and an induction system to control the operation of each driving component, so that each device can cooperate efficiently to complete the automatic blanking and loading of the coil frame 50. By cooperating with the above-mentioned devices, the coil frame 50 can be automatically unloaded and loaded, thereby greatly improving the production efficiency of electrical components and reducing labor costs.

[0026] The variable-pitch unloading mechanism is arranged on the frame 40, and the frame 40 has a first end and a second end opposite to each other in the X-axis direction. In this embodiment, there are four loading platforms, which are arranged at intervals along the X-axis direction. From the first end to the second end of the frame 40, there are the first loading platform 11, the second loading platform 12, the third loading platform 13, and the fourth loading platform 14; the upper end of the loading platform is provided with a clamping groove 15 for loading the coil frame 50, and the coil frame 50 can only move along the Z-axis direction in the clamping groove 15, and its degrees of freedom in the X-axis and Y-axis are limited by the clamping groove 15; in this embodiment, the loading platform is a rectangular table body, and the clamping groove 15 is recessed at the upper end of the loading platform, and the groove is opened on the upper end surface of the loading platform. The coil frame 50 enters and exits the clamping groove 15 along the Z-axis direction through the groove and is maintained in the clamping groove 15 in a horizontal posture, and its axial direction is arranged along the Y-axis direction. The coil frame 50 has a degree of freedom in the X-axis direction. The clamping groove 15 is restricted by the groove wall, and the inner wall of the groove wall is an arc surface to adapt to the shape of the coil frame 50. The freedom of the coil frame 50 in the Y-axis direction is restricted by two baffles 151 with U-shaped notches. The clamping groove 15 of the above structure can maintain the spacing and posture of the coil frame 50 through its own structure, and no other clamping device is required; to facilitate the processing of the clamping groove 15, one of the baffles 151 is integrally formed with the loading platform, and the other baffle 151 is processed separately and fixed to the loading platform with bolts. The U-shaped notch is set to facilitate unloading by the unloading device and picking up by the picking device. In the winding station 81, the coil frame 50 is inserted on the insertion rod, and when the picking device transfers the coil frame 50 to the coil column 72, it also uses the picking rod 62 to insert into the axial hole of the coil frame 50 for transfer. The U-shaped notch can make way for the insertion rod and the picking rod 62.

[0027] The unloading device includes an unloading drive and an unloading guide. There are four unloading drives, which correspond to the loading platforms one by one, and drive each loading platform to move along the Y-axis direction to complete the unloading action. In this embodiment, the unloading drive adopts an unloading cylinder 21, and the piston rods of the four unloading cylinders 21 are respectively fixed to the four loading platforms to make the loading platforms move in the Y-axis direction, which is simple and reliable; the unloading guide guides the movement of the loading platform in the Y-axis direction. In this embodiment, a slider and a slide rail are used to guide the loading platform. A first slider 22 is fixed on the lower end surface of each loading platform, and the length direction of the first slide rail 23 is set along the Y-axis direction. The first slider 22 slides with the first slide rail 23 to guide the displacement of the loading platform in the Y-axis direction.

[0028] The variable pitch device includes a variable pitch driving member that drives the four loading platforms to gradually move closer and farther away along the X-axis direction, and a variable pitch guide member that guides the movement of each loading platform along the X-axis direction. In this embodiment, the variable pitch guide member includes four base plates arranged at intervals along the X-axis direction, from the first end to the second end of the frame 40, respectively, the first base plate 311, the second base plate 312, the third base plate 313, and the fourth base plate 314. The frame 40 is also provided with a second slide rail 32, and the length direction of the second slide rail 32 is arranged along the X-axis direction, wherein the first base plate 311, the second base plate 312, and the third base plate 313 are slidably matched with the second slide rail 32 through the second slider 33, and the fourth base plate 314 is vertically fixed to the end of the slide rail, and the base plate corresponds to the loading platform one by one. A first slide rail 23 is fixedly provided on each of them. By setting up the bottom plate, the unloading guide and the variable distance guide are combined together, which not only realizes the guidance of the movement of the loading platform in the X-axis direction and the Y-axis direction, but also makes the structure of the entire mechanism simpler and more compact; in order to ensure that the spacing between the bottom plates is always consistent with the spacing between the loading platforms, and to ensure the accuracy of the adjustment of the spacing between the loading platforms, the spacing between the bottom plates is the same as the spacing between the loading platforms, the width of the loading platform and the bottom plate in the X-axis direction is consistent, and the two side walls of the loading platform perpendicular to the X-axis direction are flush with the two side walls of the bottom plate perpendicular to the X-axis direction; positioning plates are fixed on both ends of the bottom plate in the Y-axis direction, namely the first positioning plate 16 and the second positioning plate 17, to position the movement of the loading platform in the Y-axis direction, By setting a positioning plate, the loading platform can be positioned at the limit position of movement in the Y-axis direction, so that the loading platform can better cooperate with the winding station 81 to complete the unloading; the two adjacent loading platforms are linked by a connecting pin, and the axial direction of the connecting pin is set along the X-axis direction, and each connecting pin has a relatively set plug-in end and a fixed end, the loading platform on the plug-in end side is slidably connected to the connecting pin, and the loading platform on the fixed end side is fixedly connected to the connecting pin. In this embodiment, there are three connecting pins, namely the first connecting pin 341, the second connecting pin 342, and the third connecting pin 343. The fixed end of the first connecting pin 341 is fixed to the first bottom plate 311, and the plug-in end of the first connecting pin 341 is slidably connected to the second bottom plate 312; the second connecting pin 342 The fixed end is fixedly connected to the second base plate 312, and the plugging end of the second connecting pin 342 is slidably connected to the third base plate 313; the fixed end of the third connecting pin 343 is fixedly connected to the third base plate 313, and the plugging end of the third connecting pin 343 is slidably connected to the fourth base plate 314. The above connection method makes the spacing adjustment between the base plates more stable and reliable, and can ensure the accuracy of the spacing adjustment; the four base plates are provided with through-holes and mounting holes along the X-axis direction, and the mounting hole of the first base plate 311 is coaxially arranged with the plugging hole of the second base plate 312. The fixed end of the first connecting pin 341 is fixedly connected to the mounting hole of the first base plate 311, and its plugging end is plugged into the plugging hole of the second base plate 312. The first connecting pin 341 can slide relative to the second base plate 312;Similarly, the mounting hole of the second base plate 312 is coaxially arranged with the socket of the third base plate 313. The fixed end of the second connecting pin 342 is fixedly connected to the mounting hole of the second base plate 312, and its plug-in end is plugged into the socket of the third base plate 313. The second connecting pin 342 can slide relative to the third base plate 313. The mounting hole of the third base plate 313 is coaxially arranged with the socket of the fourth base plate 314. The fixed end of the third connecting pin 343 is fixedly connected to the mounting hole of the third base plate 313, and its plug-in end is plugged into the socket of the fourth base plate 314. The third connecting pin 343 is able to slide relative to the fourth base plate 314. To prevent the connecting pins from interfering with each other during base plate movement, the three connecting pins are staggered. To prevent the plug-in ends of the connecting pins from disengaging from the sockets, each of the three connecting pins is formed with a limiting post. To ensure that the base plates can abut tightly, the third and fourth base plates 313 and 314 are provided with clearance holes that match the limiting posts. When the limiting posts enter the clearance holes, they also guide the movement of the base plates along the X-axis, making the entire pitch change process more stable and reliable.

[0029] The outer side of the first base plate 311 is fixedly connected with a traction plate 36, and the variable pitch driving member is a variable pitch cylinder 35. The piston rod of the variable pitch cylinder 35 is fixedly connected to the traction plate 36. The traction plate 36 moves along the X-axis direction under the action of the variable pitch cylinder 35, and the first base plate 311 moves together with the traction plate 36, and through the cooperation of the three connecting pins, the second base plate 312 and the third base plate 313 are driven to move in the X-axis direction in turn to change the spacing between the four loading platforms. The spacing between the four base plates is adjusted in turn, and the next spacing is adjusted after one spacing is adjusted in place, which is stable and reliable; the traction plate 36 has a first extreme position and a second extreme position under the action of the variable pitch cylinder 35. When the traction plate 36 is in the first extreme position, the spacing between the four loading platforms is the largest, and the spacing between the four clamping slots 15 is the largest. It matches the spacing between the coil frames 50 on the winding station 81 so that the coil frames 50 can accurately enter the clamping slots 15. When the traction plate 36 is in the second extreme position, the four loading platforms abut against each other. The spacing between the four clamping slots 15 matches the spacing between the coil frames 50 on the coil disk 71 so that the coil frames 50 can be accurately inserted into the coil column 72. The spacing between the coil frames 50 refers to the distance between the center axes of two adjacent coil frames 50. The spacing between the clamping slots 15 refers to the distance between the symmetrical axes of two adjacent clamping slots 15. When the spacing between the loading platforms is the largest, it can cooperate with the winding station 81 to complete unloading. When the loading platforms abut against each other, it can cooperate with the material taking device and the swinging device to complete automatic swinging. The extreme spacing is used as the target spacing, which is convenient for operation and guaranteed adjustment accuracy.

[0030] After the coil frame 50 completes winding at the winding station 81 of the winding machine 80, the four loading platforms move along the Y-axis direction toward the first positioning plate 16 under the action of the unloading cylinder 21 until the four loading platforms are all in contact with the first positioning plate 16. The loading platform is located directly below the coil frame 50, and the coil frame 50 is inserted into the insertion rod of the winding station 81. The insertion rod moves downward along the Z-axis direction and sends the coil frame 50 into the clamping slot 15. At this time, the traction plate 36 is in the first extreme position, and the spacing between the four loading platforms is the largest. The spacing between the clamping slots 15 matches the spacing between the coil frame 50 on the winding station 81, so that the coil frame 50 can accurately enter the clamping slot from the slot; after the coil frame 50 enters the clamping slot 15, the unloading cylinder 21 drives the loading platform to move along the Y-axis direction toward the second positioning plate 17, so that the coil frame 50 is separated from the insertion rod, and the unloading process is completed.

[0031] After the loading platform moves to the second positioning plate 17, the variable pitch cylinder 35 drives the traction plate 36 to move along the X-axis direction toward the second end of the machine base, so that the distance between the loading platforms gradually becomes smaller. The traction plate 36 first drives the first base plate 311 to move, and the first base plate 311 drives the first connecting pin 341 to move. The first connecting pin 341 moves in the socket of the second base plate 312 until the limiting column of the first connecting pin 341 enters the clearance hole of the third base plate 313. After the first base plate 311 abuts against the second base plate 312, it pushes the second base plate 312 to move together. When the second base plate 312 moves, it drives the second connecting pin 342 to move. The second connecting pin 341 moves in the socket of the second base plate 312 until the limiting column of the first connecting pin 341 enters the clearance hole of the third base plate 313. 342 moves in the socket of the third base plate 313 until the limiting column of the second connecting pin 342 enters the clearance hole of the fourth base plate 314. After the second base plate 312 abuts against the third base plate 313, it pushes the third base plate 313 to move together until the third base plate 313 abuts against the fourth base plate 314, and the spacing reduction process is completed. During the above process, the loading platform moves with its corresponding base plate. At this time, the traction plate 36 is in the second extreme position, the four loading platforms abut against each other, and the spacing between the four clamping grooves 15 matches the spacing of the coil frame 50 on the coil disk 71, so that the coil frame 50 can be accurately inserted into the coil column 72.

[0032] After the coil frame 50 is transferred out of the clamping groove 15 by the material taking device, the pitch-changing cylinder 35 drives the traction plate 36 to move toward the first end of the frame 40 along the X-axis direction. The traction plate 36 pulls the first base plate 311 away from the second base plate 312, and the first connecting pin 341 moves with the first base plate 311. When the limiting column of the first connecting pin 341 abuts against the side wall of the second base plate 312, the first base plate 311 pulls the second base plate 312 to move together, and the second connecting pin 342 moves with the second base plate 312. When the limiting column of the pin 342 abuts against the side wall of the third base plate 313, the second base plate 312 pulls the third base plate 313 to move together, and the third connecting pin 343 moves with the third base plate 313. When the limiting column of the third connecting pin 343 abuts against the side wall of the fourth base plate 314, the traction plate 36 moves to the first extreme position, and the spacing expansion process is completed. In the above process, the loading platform moves with its corresponding base plate. At this time, the traction plate 36 returns to the first extreme position, and the next unloading process is carried out, and this cycle is repeated.

[0033] The material picking device includes a picking frame 61, a Y-axis driving member for driving the picking frame 61 to move along the Y-axis direction, in this embodiment, the Y-axis driving member is a first cylinder 67 provided with a piston rod along the Y-axis direction, and in practice, a lead screw can also be used. The first cylinder 67 drives the picking frame 61 to move between the loading platform and the coil disk 71; a Z-axis driving member for driving the picking frame 61 to move along the Z-axis direction, in this embodiment, the Z-axis driving member is a second cylinder 68 provided with a piston rod along the Z-axis direction, and in practice, a lead screw can also be used. Using a lead screw, the second cylinder 68 drives the material picking rack 61 to move along the Z axis to remove the coil frame 50 from the notch of the clamping slot 15 and transfer it to the coil column 72 of the coil disk 71, as well as a flipping drive component for driving the material picking rack 61 to flip 90 degrees. In this embodiment, the flipping drive component is an angle cylinder 69. The angle cylinder 69 drives the material picking rack 61 to flip 90 degrees, so that the coil frame 50 on the material picking rack 61 is flipped from a horizontal state to an upright state to adapt to the clamping slot 15 and the coil disk 71 respectively.

[0034] The feeding frame 61 is fixed with a feeding rod 62. In this embodiment, there are four feeding rods 62, which are arranged at intervals. The spacing between the feeding rods 62 matches the spacing between the coil posts 72 on the coil disk 71. The spacing between the feeding rods 62 refers to the distance between the center axes of two adjacent feeding rods 62. The spacing between the coil posts 72 refers to the distance between the center axes of two adjacent coil posts 72. The axial direction of the feeding rod 62 is set along the Y-axis direction. Using the feeding rod 62 to take materials is simple and reliable. In order to prevent the coil frame 50 from falling off the feeding rod 62 during and after the turning of the feeding frame 61, two elastic card beads 63 are provided at the front end of the feeding rod 62 to limit the coil frame 50; the feeding frame 61 is also provided with a discharge plate 64, which is arranged at the rear end of the feeding rod 62 and can be moved from the rear end of the feeding rod 62 to the front end of the feeding rod 62 under the action of the discharge cylinder 65 to remove the coil frame 50 sleeved on the feeding rod 62. The connecting portion and the unloading portion are connected to the piston rod of the unloading cylinder 65. The unloading portion is provided with a make way groove 641 for making way for the picking rod 62. The width of the make way groove 641 is larger than the outer diameter of the picking rod 62, but smaller than the outer diameter of the coil frame 50, so as to ensure that the unloading plate 64 can unload the coil frame 50. In order to ensure that the unloading plate 64 has sufficient thrust, the unloading plate 64 and the unloading cylinder 65 are both provided with two in this embodiment. Each unloading plate 64 is provided for the two picking rods 62. The coil frame 50 is unloaded, and the coil frame 50 mounted on the material removal rod 62 is pushed into the coil disk 71; in order to further improve the unloading reliability of the unloading plate 64, a guide column 66 is also fixed on the material removal frame 61. The axial direction of the guide column 66 is consistent with the moving direction of the unloading plate 64, and a guide hole matching the guide column 66 is opened on the unloading plate 64. The unloading plate 64 is mounted on the guide column 66. The unloading plate 64 unloads under the guidance of the guide column 66 without deviation.

[0035] The loading device includes a coil disk 71 and a movement driving component for driving the coil disk 71 to move. A plurality of coil posts 72 for fixing the coil frame 50 are arrayed on the coil disk 71. The axial direction of the coil post 72 is arranged along the Z-axis direction. The number of coil posts 72 arranged in the X-axis direction is an integer multiple of the number of the feeding rods 62. In this embodiment, the number of coil posts arranged in the X-axis direction is eight, and the spacing of the coil posts 72 in the X-axis direction matches the spacing of the feeding rods 62 to ensure that the coil frame 50 on the feeding rods 62 can be accurately inserted into the coil posts 72; the movement driving component is a two-axis module slide 73, which drives the coil disk 71 to move along the X-axis direction and the Y-axis direction, so that the coil posts 72 are taken turns to be located below the feeding rod 62 for loading, until all the coil posts 72 are inserted with coil frames 50, and the loading of the coil disk 71 is completed.

[0036] After the loading platform completes the pitch change, the material picker 61 moves toward the loading platform along the Y-axis direction under the drive of the first cylinder 67. After the material picker rod 62 is inserted into the shaft hole of the coil frame 50, the second cylinder 68 drives the material picker 61 to move upward along the Z-axis direction. The material picker rod 62 moves upward along with the material picker 61 and takes the coil frame 50 out of the notch of the clamping slot 15. Then the first cylinder 67 drives the material picker 61 to move along the Y-axis direction to the top of the coil disk 71. The corner cylinder 69 drives the material picker 61 to rotate 90 degrees, and the coil frame 50 changes from a horizontal state to an upright state to accommodate the coil. The disk 71 and the coil disk 71 are moved and aligned in the X-axis direction and the Y-axis direction under the drive of the two-axis module slide 73. A group of coil posts 72 to be loaded with the coil frame 50 are located below the material picking rack 61 and are accurately aligned with the material picking rod 62. The unloading cylinder 65 drives the unloading plate 64 to move downward along the Z-axis direction and pushes the coil frame 50 on the material picking rod 62 toward the coil post 72 until the coil frame 50 is fitted on the coil post 72. The unloading and loading work of a group of coil frames 50 is completed, and each device returns to its original position and cooperates with the unloading variable pitch structure to complete the next unloading and loading work.

[0037] The variable-pitch blanking and loading machine disclosed in the present invention can realize automatic blanking and loading of the coil frame 50 through the cooperation of the blanking device, the variable-pitch device, the material taking device, and the loading device, thereby greatly improving the production efficiency of electrical components and reducing labor costs; each device has a reasonable layout, a simple and compact structure, and reliable operation, which can ensure accurate and efficient blanking and loading of the coil frame 50.
