Description

[Technical Field]

[0001] This utility model belongs to the technical field of inductor coil manufacturing equipment, and in particular relates to a chain-linked inductor coil flattening machine. [Background Technology]

[0002] An inductor coil is an inductor that can be used at high frequencies. It has a simple structure, excellent performance, and a wide range of wire specifications. It is especially suitable for inductor molding technology. One-piece molded inductors are formed by die casting a coil wound with round copper wire and iron powder in one piece using a special process. They have the characteristics of high current resistance and low impedance.

[0003] During the manufacturing process, inductor coils need to be placed into a punching die to flatten their leads, thus requiring an automatic flattening machine. Existing patent CN214312930U discloses an automatic inductor coil flattening machine that uses a circulating chain to continuously transport the inductor coil to the punching machine for flattening. However, this chain is driven by a separate motor, resulting in high energy consumption. Furthermore, during the process of moving the inductor coil to the flattening station, the chain is prone to vertical movement, leading to poor positional accuracy when the inductor coil reaches the flattening station. Even after reaching the flattening station, the inductor coil is susceptible to positional deviation due to chain or machine vibration, causing the punch to deviate.

[0004] Therefore, it is necessary to provide a new chain-linked inductor coil flattening machine to solve the above-mentioned technical problems. [Utility Model Content]

[0005] The main purpose of this utility model is to provide a chain-linked inductor coil flattening machine, which can effectively improve the transmission accuracy and flattening operation accuracy of the inductor coil, realize the linkage drive of the punch press, and effectively reduce energy consumption and production costs.

[0006] This utility model achieves the above objective through the following technical solution: a chain-linked inductor coil flattening machine, comprising:

[0007] A flattening punch includes a lifting plate that moves up and down, a flattening punch mounted on the lifting plate, and a flattening base located below the flattening punch.

[0008] The transmission chain is composed of several chain blocks connected together, and each chain block has a positioning rod at the top and a driving groove at the bottom.

[0009] A chain drive assembly carries the transmission chain to the left and includes a mounting block that is movable to the left and right and a drive member that is rotatably mounted on the mounting block. The top of the drive member is provided with a drive part that extends into the drive groove. The drive member remains in the drive groove when moving to the left and is forced to rotate and disengage from the drive groove when moving to the right.

[0010] The linkage component includes a slider that is movable left and right, a transmission wedge fixedly connected to the slider, a drive roller fixed on the lifting plate and cooperating with the transmission wedge for transmission, and a third elastic element that holds the slider to the left; the mounting block is fixed on the slider, and the transmission wedge cooperates with the drive roller to convert the lifting motion of the lifting plate into the left and right motion of the slider.

[0011] Furthermore, the driving member has an L-shaped first section and a second section, the first section extending horizontally and the second section extending vertically; the middle part of the driving member is rotatably mounted on the mounting block via a second pivot, forming a lever structure; the driving part is fixedly mounted on the first section; a second elastic member is provided on the mounting block below the first section, the second elastic member pushing the first section upward, so that the driving part maintains the tendency to extend upward into the driving groove; the second pivot extends in the front-rear direction.

[0012] Furthermore, the mounting block is provided with a limiting stop portion at the position corresponding to the second section to restrict the clockwise rotation of the second section, and has a rotation space below the first section for the first section to rotate counterclockwise.

[0013] Furthermore, it also includes a clamping assembly; the clamping assembly includes a first mounting base, a first rotating shaft rotatably disposed on the first mounting base and extending in the front-rear direction, a pair of first rotating arms fixed on the first rotating shaft, and a clamping plate fixed to the end of the first rotating arms and clamping the inductor coil on the flattened base.

[0014] Furthermore, a second rotating arm is fixedly mounted on the first rotating shaft, and a transmission link is hinged to the end of the second rotating arm. The other end of the transmission link is hinged to the slider or the mounting block, thereby converting the left and right movement of the slider into the rotational movement of the first rotating shaft.

[0015] Furthermore, it also includes a chain positioning component for positioning and locking the transmission chain; the chain positioning component includes a second mounting base, a positioning push rod that is movably disposed on the second mounting base and cooperates with the drive groove, and a first elastic member located below the positioning push rod and pushing the positioning push rod upward.

[0016] Furthermore, the chain positioning assembly also includes a first drive plate, and the bottom end of the positioning top rod is provided with a through mounting groove; the first drive plate is movably disposed in the mounting groove and its left and right ends extend beyond the positioning top rod; a limiting rod is installed in the height section of the mounting groove corresponding to the positioning top rod, penetrating from front to back between the positioning top rod and the first drive plate; the first drive plate is provided with a drive guide groove that cooperates with the limiting rod, converting the left and right movement of the first drive plate into the lifting movement of the positioning top rod.

[0017] Furthermore, the vertical height of the mounting groove is greater than the vertical height of the first drive plate; the second mounting base is provided with a guide groove that restricts the first drive plate to slide only left and right; the opening of the guide groove faces downward, and the top of the first drive plate extends into the guide groove.

[0018] Furthermore, the first drive plate has a first working position and a second working position; when the first drive plate moves to the left to the first working position, the positioning push rod is driven to the low position and is in a retracted state; when the first drive plate moves to the right to the second working position, the positioning push rod is driven to the high position and is in an extended state.

[0019] Furthermore, the mounting block is provided with a second drive plate, the left end of which extends to the left side of the first drive plate and drives the first drive plate to move to the right to the second working position as the mounting block moves to the right; the mounting block has a driving surface aligned with the right side of the first drive plate, and drives the first drive plate to move to the left to the first working position as the mounting block moves to the left.

[0020] Furthermore, when the second drive plate moves to the left along with the mounting block, there is a set distance between the second drive plate and the first drive plate; when the mounting block moves to the right, there is a set distance between the driving surface and the first drive plate.

[0021] Compared with existing technologies, the advantages of this chain-linked inductor coil flattening machine are: it effectively improves the transmission accuracy and flattening operation accuracy of the inductor coil, realizes the linkage drive of the punch press, and effectively reduces energy consumption and production costs. Specifically:

[0022] (1) By setting up a chain drive assembly, the inductor coil is continuously conveyed by directly driving the transmission chain with horizontal power. By setting up a linkage assembly, the lifting motion of the flattening punch is used as the source of horizontal driving force for the chain drive assembly. By cooperating with the drive roller and the transmission wedge, the lifting motion of the flattening punch is converted into the horizontal motion of the chain drive component, thereby realizing the linkage between the flattening action and the conveying action, which greatly improves the synchronization and consistency of the two actions.

[0023] (2) By setting up a clamping component, when the inductor coil reaches the flattening station, it is clamped by a clamping plate to ensure that the position of the inductor coil is accurate and stable before the pin is flattened, and will not be offset due to the vibration of the transmission chain or the equipment, thus ensuring the flattening accuracy and quality of the inductor coil.

[0024] (3) In the linkage transmission of the chain drive assembly, the lifting motion of the flattening punch has been converted into the horizontal motion of a mounting block. By further utilizing the horizontal motion of the mounting block, the horizontal motion of the mounting block is further converted into the rotational motion of the shaft by setting up a transmission link, a rotating arm and a rotating shaft structure, thereby driving the pressing plate on the pressing assembly to achieve pressing and releasing actions, saving the additional setting of the power mechanism in the pressing assembly, and reducing equipment cost and energy consumption;

[0025] (4) By setting up a chain positioning component, the position of the chain is accurately positioned, which further ensures the conveying accuracy of the inductor coil, thereby improving the reliability and effectiveness of the inductor coil flattening operation.

[0026] (5) On the premise of converting the lifting motion of the flattening punch into the horizontal motion of the mounting block, the horizontal motion of the mounting block is further utilized. By setting the second drive plate and the driving action surface on the mounting block, and in conjunction with the transmission structure design of the bottom end of the positioning rod in the chain positioning assembly, the horizontal motion of the first drive plate is used to realize the lifting motion of the positioning rod, thereby realizing the lifting positioning and lowering avoidance of the transmission chain; then, by using the second drive plate and the driving action surface, the left and right sides of the first drive plate are pushed respectively during the left and right movement of the mounting block, thereby realizing the left and right driving of the first drive plate, and then realizing the lifting drive of the positioning rod. This saves the additional setting of the lifting drive mechanism in the chain positioning assembly, and reduces equipment cost and energy consumption. [Attached Image Description]

Detailed Implementation Methods

[0047] Example 1:

[0048] Please refer to Figures 1-11 This embodiment is a chain-linked inductor coil flattening machine 100, which includes a flattening punch 1, a transmission chain 2 for conveying inductor coils 200 to the flattening punch 1, a feeding mechanism 3 disposed at one end of the transmission chain 2, a clamping assembly 4 for positioning and pressing the inductor coils 200 on the flattening punch 1, a chain positioning assembly 5 for pausing and positioning the transmission chain 2, and a chain driving assembly 6 for driving the transmission chain 2 to perform horizontal transmission.

[0049] The flattening punch 1 includes a punch press main unit 11, a lifting plate 12 located at the movable end of the punch press main unit 11 and moving up and down, a flattening punch 13 fixed to the lower surface of the lifting plate 12, and a flattening base 14 located below the flattening punch 13. The flattening base 14 is provided with a movable through groove 141 that runs from left to right for the transmission chain 2 to pass through.

[0050] The transmission chain 2 is composed of several chain blocks 21 connected one after the other. Each chain block 21 has a support plane 211 on its top for supporting the inductor coil 200 and a drive groove 212 on its bottom for driving the chain drive assembly 6. A positioning rod 213 for positioning the inductor coil 200 is provided on the support plane 211. The positioning rod 213 passes through the central hole of the inductor coil 200 to achieve positioning.

[0051] The feeding mechanism 3 includes an inductor feeding module 31 and a feeding and handling module 32 that takes out the inductor coil 200 from the inductor feeding module 31 and places it onto the conveyor chain 2. Both the inductor feeding module 31 and the feeding and handling module 32 can adopt existing structures; this embodiment does not limit their structure. In this embodiment, the inductor feeding module 31 uses a vibratory feeder for automatic feeding. The feeding and handling module 32 uses a cylinder to mount a two-dimensional linear transfer module, which, in conjunction with a gripper cylinder, realizes the picking, placing, and handling of the inductor coil.

[0052] To reduce costs, this embodiment fully utilizes the up-and-down movement of the flattening punch 1, using it as the power source for driving the clamping assembly 4, the chain positioning assembly 5, and the chain drive assembly 6, thus creating a linked flattening machine that works in conjunction with the flattening punch 1. Specifically:

[0053] The clamping assembly 4 includes a first mounting base 41, a first rotating shaft 42 rotatably mounted on the first mounting base 41 and extending in the front-rear direction, a pair of first rotating arms 43 fixed on the first rotating shaft 42, and a clamping plate 44 fixed at the end of the first rotating arms 43 and clamping the inductor coil 200 on the flattening base 14. The two first rotating arms 43 are located on opposite sides of the transmission chain 2, and the two clamping plates 44 at their ends respectively clamp the two pins of the same inductor coil 200. By rotating the first rotating shaft 42, the first rotating arms 43 are driven to swing around the first rotating shaft 42, which in turn drives the clamping plate 44 to perform clamping and releasing actions. When the inductor coil 200 moves to the flattening station, the clamping plate 44 clamps the inductor coil 200. When the flattening punch 13 moves downward, the clamping plate 44 gradually retracts, ensuring that the position of the inductor coil 200 is accurate and reliable before the flattening punch 13 acts on the pin. By pressing the inductor coil 200 with the clamping component 4, the position of the inductor coil 200 can be effectively prevented from shifting due to the vibration of the transmission chain 2 or the vibration of the whole equipment, thus ensuring that the flattening operation is accurate and reliable.

[0054] The chain positioning assembly 5 includes a second mounting base 51, a positioning push rod 52 that is movably mounted on the second mounting base 51 and cooperates with the drive groove 212, and a first elastic member 53 located below the positioning push rod 52 and pushing the positioning push rod 52 upward. The chain positioning assembly 5 is mainly used to fix the position of the transmission chain 2 when it stops moving, so that it is stably and reliably maintained in the stationary position and will not be displaced by external factors or the chain drive assembly 6. When the transmission chain 2 needs to be kept in a stopped state, the positioning push rod 52 is extended upward; when the transmission chain 2 needs to be kept in a moving state, the positioning push rod 52 needs to be moved downward to switch to a retracted state.

[0055] To achieve the lifting and lowering drive of the positioning top rod 52, the chain positioning assembly 5 also includes a first drive plate 54. The bottom end of the positioning top rod 52 is provided with a through mounting groove 521. The first drive plate 54 is movably disposed in the mounting groove 521 and extends out of the positioning top rod 52 at both ends. A limiting rod 55 is installed in the height section of the mounting groove 521 corresponding to the positioning top rod 52 and the first drive plate 54, which passes through the positioning top rod 52 and the first drive plate 54. The first drive plate 54 is provided with a drive guide groove 541 that cooperates with the limiting rod 55. The vertical height of the mounting groove 521 is greater than the vertical height of the first drive plate 54, so that when the first drive plate 54 moves left and right, under the guidance of the drive guide groove 541, the limiting rod 55 is constrained and the positioning top rod 52 moves up and down.

[0056] The drive guide groove 541 has a first working groove 5411 and a second working groove 5412, which are offset in the left-right direction and have a height difference in the up-down direction. The groove shape of the first working groove 5411 and the second working groove 5412 is partially modeled with that of the limiting rod 55. When the limiting rod 55 is located in the first working groove 5411, the positioning push rod 52 is driven to the low position and is in a retracted state; when the limiting rod 55 is located in the second working groove 5412, the positioning push rod 52 is driven to the high position and is in an extended state.

[0057] To ensure that the positioning rod 52 can be driven to move up and down during the left and right movement of the first drive plate 54, the first drive plate 54 must not move up and down during the left and right movement. At the same time, to ensure that the first drive plate 54 does not tilt forward or backward during the left and right movement and to ensure the lifting and lowering driving function of the positioning rod 52, this embodiment provides a guide groove 511 on the second mounting base 51 to limit the left and right sliding path of the first drive plate 54. The opening of the guide groove 511 faces downward, and the top of the first drive plate 54 extends into the guide groove 511. The guide groove 511 limits the left and right sliding trajectory of the first drive plate 54 to ensure that the first drive plate 54 does not tilt forward or backward during the left and right movement, and limits the height of the first drive plate 54 to ensure that the first drive plate 54 does not move up and down during the left and right movement.

[0058] During the left and right movement of the first drive plate 54, there is a possibility of over-movement. To limit the left and right movement range of the first drive plate 54 and ensure that the first working groove 5411 and the second working groove 5412 can be accurately moved into place, a limiting protrusion 542 is provided on each of the left and right sides of the positioning push rod 52 on the first drive plate 54. The limiting protrusion 542 protrudes horizontally outward by a set length so that the limiting protrusion 542 will not enter the mounting groove 521, thereby limiting the left and right movement range of the first drive plate 54.

[0059] The chain drive assembly 6 includes a mounting block 61 that is movably positioned to the left and right, and a drive member 62 that is rotatably mounted on the mounting block 61. One end of the drive member 62 is provided with a drive portion 621 that cooperates with the drive groove 212 to achieve transmission. The end of the drive member 62 near the drive portion 621 is held upward by a second elastic member 63, so that the drive portion 621 maintains a rotational tendency to extend upward into the drive groove 212. When the drive portion 621 extends into the drive groove 212, if the drive member 62 moves to the left, the other end of the drive member 62 is constrained by the mounting block 61 and does not have the freedom to rotate counterclockwise, thus forcing the drive portion 621 to remain in the drive groove 212, thereby driving the chain block 21 to move to the left, realizing horizontal drive of the transmission chain 2; if the drive member 62 moves to the right, the drive portion 621 is constrained by the chain block 21, so that the drive member 62 has a tendency to rotate clockwise, and the second elastic member 63 is below the end of the drive member 62 near the drive portion 621, which also makes that end capable of clockwise rotation. The spatial conditions; as the drive member 62 continues to move to the right in conjunction with the clockwise rotation of the drive member 62, the drive part 621 gradually disengages from the drive groove 212. When it is completely disengaged, the drive member 62 can continue to move to the right to the drive starting position. After moving to the right and being in place, under the lifting action of the second elastic member 63, the drive member 62 rotates counterclockwise to the position, and the drive part 621 extends upward into the drive groove 212, switching the moving direction of the drive member 62. The drive part 621 then drives the chain block 21 to move to the left, and then drives the transmission chain 2 to transmit to the left, realizing the horizontal transfer drive of the next cycle.

[0060] In this embodiment, the driving member 62 has an L-shaped first section 622 and a second section 623. The first section 622 extends horizontally, and the second section 623 extends vertically. The middle part of the driving member 62 is rotatably mounted on the mounting block 61 via a second pivot 64, so that the driving member 62 forms a lever structure. The first section 622 and the second section 623 are the two lever arms of this lever structure. The driving part 621 is fixedly mounted on the horizontally extending first section 622. The lower part of the first section 622 is pushed upward by a second elastic member 63, so that the first section 622 maintains an upward rotational trend, thereby allowing the driving part 621 to extend upward into the driving groove 212 at the bottom of the chain block 21. The mounting block 61 has a limiting stop 611 at the position corresponding to the second section 623 to restrict the clockwise rotation of the second section 623, and a rotation space 613 corresponding to the lower part of the first section 622 for the first section 622 to rotate counterclockwise. The second rotating shaft 64 extends in the front-to-back direction.

[0061] To achieve linkage between the flattening punch 1 and the chain drive assembly 6, and to link the flattening operation with the movement frequency of the transmission chain 2, thereby improving the synchronization and consistency of the two actions, this embodiment includes a linkage assembly 7. Specifically, the linkage assembly 7 includes a third mounting base 71, a slide rail 72 extending left and right on the third mounting base 71, a slider 73 sliding left and right on the slide rail 72, a transmission wedge 74 fixedly connected to the slider 73, a third elastic element 75 that holds the slider 73 to the left to maintain its leftward movement, and a drive roller 76 fixed on the lifting plate 12 and cooperating with the transmission wedge 74; the mounting block 61 in the chain drive assembly 6 is fixedly mounted on the slider 73, enabling left and right movement. In this embodiment, the transmission wedge 74 is fixed on the mounting block 61, specifically mounted on the upper surface of the mounting block 61.

[0062] When the flattening press 1 performs the flattening operation, the lifting plate 12 moves downward, carrying the drive roller 76 downward. With the cooperation of the transmission wedge 74 and the drive roller 76, the lifting motion of the drive roller 76 is converted into the horizontal left-right movement of the transmission wedge 74, which in turn drives the slider 73 to move to the right. Since the mounting block 61 is fixedly mounted on the slider 73, it then drives the chain drive assembly 6 to move to the right, providing a power source for the chain drive assembly 6. After the flattening operation is completed, the lifting plate 12 moves upward, the drive roller 76 releases its driving force on the transmission wedge 74, and the mounting block 61, under the action of the third elastic element 75, moves to the left, thereby driving the transmission chain 2 to move to the left, conveying the transmission chain 2 to the left by a set length. Therefore, the flattening action of the flattening press 1 and the transmission action of the transmission chain 2 are linked.

[0063] To further utilize the lifting motion of the lifting plate 12 as the power source for the pressing assembly 4, this embodiment further designs the structure of the linkage assembly 7. Specifically, the linkage assembly 7 also includes a second rotating arm 77 with one end fixed to the first rotating shaft 42 and a transmission link 78 with one end hinged to the end of the second rotating arm 77 and the other end hinged to the slider 73. When the slider 73 moves left and right, the second rotating arm 77 is driven to swing under the transmission action of the transmission link 78, which in turn drives the first rotating shaft 42 to rotate, and then drives the first rotating arm 43 to swing, thereby realizing the pressing and releasing action of the pressing plate 44, and completing the power utilization of the lifting plate 12.

[0064] To further utilize the lifting motion of the lifting plate 12 as the power source for the chain positioning assembly 5, this embodiment further refines the structural design of the linkage assembly 7. Specifically, the linkage assembly 7 also includes a second drive plate 79 fixed to the mounting block 61. The left end of the second drive plate 79 extends to the left side of the first drive plate 54. The mounting block 61 has a driving surface 612 facing the right side of the first drive plate 54 and acting on the leftward movement of the first drive plate 54. When the lifting plate 12 moves upward, the drive roller 76 releases the driving force on the transmission wedge 74, and the mounting block 61 is driven to move to the left under the action of the third elastic member 75. The driving surface 612 pushes the right side of the first drive plate 54 to the left, realizing the first... The leftward movement of the drive plate 54 causes the second working groove 5412 to act as the limiting rod 55, and under the action of the first elastic element 53, the positioning rod 52 extends upward. When the lifting plate 12 moves downward, with the cooperation of the transmission wedge block 74 and the drive roller 76, the mounting block 61 is driven to move to the right, compressing the third elastic element 75. The mounting block 61 moves to the right along with the second drive plate 79, and the second drive plate 79 pushes the first drive plate 54 to the right, causing the first working groove 5411 to act as the limiting rod 55, pressing the positioning rod 52 downward to the low position. Therefore, the lifting movement of the lifting plate 12, under the transmission action of the linkage component 7, realizes the lifting drive of the chain positioning component 5.

[0065] In this embodiment, when the second drive plate 79 is located on the left side, there is a set gap between it and the first drive plate 54. The purpose of this design is that, for a period of time before the mounting block 61 moves the drive member 62 to the right and into position, the positioning rod 52 can still maintain the lifting state to lock the position of the transmission chain 2, preventing the drive member 62 from moving to the right relative to the transmission chain 2 and causing the transmission chain 2 to move to the right, thus causing the conveying sequence to be disordered; when the drive member 62 is about to move to the right and into position, the second drive plate 79 acts on the first drive plate 54, and when the drive member 62 moves to the right and into position, the positioning rod 52 is driven to the retracted state. Similarly, when the mounting block 61 is in the right position, there is also a set distance between it and the first drive plate 54. For a period of time before the mounting block 61 moves to the left, the positioning rod 52 remains in a retracted state to ensure that the drive component 62 will not be blocked or interfered with when it moves to the left with the transmission chain 2. When the drive component 62 is about to be delivered to the left with the transmission chain 2, the driving action surface 612 acts on the first drive plate 54. When the drive component 62 moves to the left, the positioning rod 52 is driven to the lifting state.

[0066] The working principle of the chain-linked inductor coil flattening machine 100 in this embodiment is as follows: In the initial state, the lifting plate 12 is in a high position, the mounting block 61 is in the left position (drive end point), the positioning top rod 52 is in the raised state, and the pressing plate 44 is in the pressing state.

[0067] (1) The feeding mechanism 3 automatically supplies inductor coils and transports them one by one to the transmission chain 2. The inductor coils 200 are positioned by the positioning rod 213 on the transmission chain 2. The transmission chain 2 carries the inductor coils 200 to the flattening station at equal intervals.

[0068] (2) The lifting plate 12 descends, and the driving mounting block 61 moves to the right to the right side position (driving start point). Under the transmission of the transmission link 78, the driving clamping plate 44 is released to avoid the impact. Under the action of the second driving plate 79, the driving positioning top rod 52 moves downward. When the lifting plate 12 descends to the position, the flattening punch 13 completes the flattening operation of the inductor coil.

[0069] (3) The lifting plate 12 rises, and under the action of the third elastic element 75, it drives the mounting block 61 to move to the left, moving the transmission chain 1 to the left by a set distance. The next inductor coil 200 moves to the flattening station. At the same time, the driving clamping plate 44 gradually switches to the clamping state. When the inductor coil 200 moves into place, the inductor coil is clamped. As the mounting block 61 moves to the left into place, under the action of the driving action surface 612, the first driving plate 54 is pushed to the left, which in turn drives the positioning rod 53 to move upward, positioning the transmission chain 1, ensuring the transmission accuracy of the transmission chain 1, realizing the accurate transmission of the next inductor coil, and under the clamping action of the clamping plate 44, ensuring the position accuracy of the inductor coil before flattening.

[0070] (4) Repeat steps (2) to (3) to achieve continuous flattening and conveying of the inductor coil.
