Technical Field
[0001] This utility model relates to the field of surface mount inductor manufacturing technology, and in particular to a tooling for calibrating NG products of leadboards. Background Technology
[0002] In the field of electronic component manufacturing, surface mount inductors are commonly used electronic components. Their performance stability and reliability directly depend on the processing quality of key semi-finished products during the production process, namely the inductor coil assembly. The leadboard, as a core component of the inductor coil assembly, is the basic carrier for fixing and assembling multiple inductor coils (such as...). Figure 1 (As shown in the diagram): Specifically, the inductor coil assembly consists of a conductor plate and multiple inductor coils, which are fixedly connected by spot welding. If the conductor plate is warped, uneven gaps and loose fits between the conductor plate and the inductor coils will occur during spot welding, easily leading to poor solder joints and decreased conductivity. However, the conductor plate is prone to warping during punching and heat treatment due to factors such as material stress release and temperature gradient changes, therefore, it must be shaped using specialized tooling. Currently, most lead plate straightening fixtures used in the industry employ rigid drive structures. For example, a cylinder directly pushes the straightening mold downwards, or a motor works with a lead screw to achieve rigid lifting. However, in rigid drive mode, the force exerted by the straightening mold on the lead plate lacks buffering and adjustment space. When the lead plate warps unevenly, the local stress can easily exceed the material's yield limit instantaneously, resulting in obvious indentations on the lead plate and rendering it completely unusable. In addition, some improved tooling attempts to achieve buffering by adding rubber pads in the drive path. However, the elastic coefficient of the rubber pads is prone to change with the time of use and the ambient temperature. After long-term use, the buffering effect is significantly reduced, making it difficult to maintain stable alignment accuracy. Moreover, the deformation recovery ability of the rubber pads is limited. When the drive unit drives the alignment mold to rise, the rubber pads cannot provide reliable reset traction force, which can easily lead to problems such as alignment mold jamming and asynchronous lifting, affecting the alignment efficiency of the guide plate.
[0003] Therefore, it is urgent for technical personnel to solve the above problems. Utility Model Content
[0004] The purpose of this utility model is to provide a tooling for calibrating non-compliant leadboards, which aims to solve the problems of rigid drive causing easy damage to the leadboard, easy decay of the rubber pad buffer effect and unreliable reset, as well as low calibration efficiency in the existing design. It achieves non-rigid thrust transmission through elastic buffer components, so as to balance calibration quality and efficiency.
[0005] This utility model relates to a tooling for calibrating non-compliant conductor boards, including a frame, a support fixture, a calibration mold, and a drive unit; The support fixture, the straightening mold, and the drive unit are all mounted on the frame. The support fixture is used to support the conductor board to be straightened, and the straightening mold is set to the support fixture to correct the warping deformation of the conductor board. The drive unit includes a manual push-pull mechanism, a load-bearing seat, a sliding seat, an elastic buffer assembly, and a guide assembly; The alignment mold is fixedly installed on the sliding seat; the elastic buffer component is set between the load-bearing seat and the sliding seat; the manual push-pull device is connected to the load-bearing seat to drive the load-bearing seat, and the guide component cooperates with the sliding seat to guide the sliding seat to perform lifting and lowering movements; When the manual push-pull device drives the support seat to move, the thrust is transmitted to the sliding seat through the elastic buffer component, causing the sliding seat to drive the shaping mold to perform lifting and lowering movements to approach or move away from the support fixture. The thrust on the sliding seat is a non-rigid force through the elastic buffer component.
[0006] As a further improvement to the technical solution disclosed in this utility model, the elastic buffer assembly includes a left bolt assembly, a right bolt assembly, a left columnar spring, and a right columnar spring. Both the left-side bolt assembly and the right-side bolt assembly penetrate the bearing seat and the sliding seat in the vertical direction to achieve a through-connection between the bearing seat and the sliding seat; The left-side columnar spring is sleeved on the outer periphery of the left-side bolt assembly, and the left-side columnar spring elastically presses against the bearing seat and the sliding seat; A right-side columnar spring is sleeved on the outer periphery of the right-side bolt assembly, and the right-side columnar spring elastically presses against the bearing seat and the sliding seat; When the bearing seat moves downward under the drive of the manual push-pull mechanism, the left and right columnar springs are compressed and stored due to the pressure of the bearing seat. The sliding seat moves downward under the elastic pushing force released by the left and right columnar springs. When the support seat moves upward under the drive of the manual push-pull mechanism, the left and right bolt assemblies rise with the support seat and exert an upward pulling force on the sliding seat, thus enabling the sliding seat to move upward.
[0007] As a further improvement to the technical solution disclosed in this utility model, the left-side bolt assembly and the right-side bolt assembly have the same structure; the left-side bolt assembly includes a bolt body and a nut; The bolt body passes through the bearing seat and the sliding seat in sequence along the vertical direction, and the outer peripheral surface of the bolt body is in clearance fit with the inner wall of the through hole of the bearing seat and the sliding seat. The nut is threaded onto the lower end of the bolt body to restrict the bolt body from moving upward relative to the sliding seat and to provide force support for the sliding seat when it rises.
[0008] As a further improvement to the technical solution disclosed in this utility model, the number of guide components is 2, and they are evenly distributed along the width direction of the sliding seat; the guide components include a slide rail and a slider; the slide rail is fixedly installed on the frame in the vertical direction; the slider is fixedly connected to the back of the sliding seat and slides in cooperation with the slide rail.
[0009] As a further improvement to the technical solution disclosed in this utility model, the side of the calibration mold facing the supporting fixture is provided with a calibration plane; the area of the calibration plane is not less than the upper surface area of the guide plate to be calibrated, and its flatness error is not greater than 0.02mm.
[0010] As a further improvement to the technical solution disclosed in this utility model, the upper surface of the support fixture is provided with a positioning recess that is adapted to the shape of the guide plate to be shaped; the depth of the positioning recess is less than the thickness of the guide plate to be shaped; when the guide plate to be shaped is placed in the positioning recess, the convex part caused by its warping deformation protrudes out of the positioning recess.
[0011] In practical applications, the guide plate NG product straightening fixture disclosed in this utility model can achieve at least the following beneficial technical effects, specifically: 1) When the manual push-pull device drives the bearing seat to move, the elastic buffer component gently transmits the thrust to the sliding seat, which in turn drives the straightening mold fixed to the sliding seat to press against the guide plate to be straightened. In this way, on the one hand, it can effectively avoid obvious indentations on the guide plate due to local rigid force; on the other hand, the force can be evenly applied to the surface of the guide plate and accurately applied to the warped parts, effectively improving the correction accuracy of the warped deformation of the guide plate, thereby realizing the efficient reuse of the guide plate. 2) The manual push-pull device allows for precise control of the straightening force and the lifting speed of the straightening mold through manual operation: when dealing with slightly warped guide plates, the force can be reduced and the speed slowed down for fine correction; when dealing with severely warped guide plates, the parameters can be adjusted appropriately to ensure the correction effect, flexibly adapting to the needs of guide plates with different degrees of warping.

Detailed Implementation
[0019] The present invention will be further described in detail below with reference to specific embodiments. Figure 2 A three-dimensional schematic diagram of the lead-board NG product straightening fixture disclosed in this utility model is shown. It can be seen that it mainly consists of a frame 1, a support fixture 2, a straightening mold 3, and a drive unit 4. The support fixture 2, the straightening mold 3, and the drive unit 4 are all mounted on the frame 1 and are all detachably fixed. The support fixture 2 is used to support the lead-board to be straightened. The straightening mold 3 is positioned corresponding to the support fixture 2, and has a straightening plane on its side facing the support fixture 2. The straightening mold 3 performs a lifting and lowering movement under the pushing and pulling force from the drive unit 4, thereby correcting the warping deformation of the lead-board. like Figure 3 , Figure 4 As shown, the drive unit 4 includes a manual push-pull device 41, a support seat 42, a sliding seat 43, an elastic buffer assembly 44, and a guide assembly 45. The shaping mold 3 is fixedly installed on the sliding seat 43, while the elastic buffer assembly 44 is disposed between the support seat 42 and the sliding seat 43; the manual push-pull device 41 is connected to the support seat 42 to drive the support seat 42 to move, and the guide assembly 45 cooperates with the sliding seat 43 to guide the sliding seat 43 to perform lifting and lowering movements.
[0020] As Figure 4As shown, the elastic buffer assembly 44 includes a left bolt assembly 441, a right bolt assembly 442, a left columnar spring 443, and a right columnar spring 444. Both the left bolt assembly 441 and the right bolt assembly 442 penetrate the support seat 42 and the sliding seat 43 in the vertical direction to achieve a through-connection between them. The left columnar spring 443 is sleeved on the outer periphery of the left bolt assembly 441 and elastically presses against the support seat 42 and the sliding seat 43. The right columnar spring 444 is sleeved on the outer periphery of the right bolt assembly 442 and elastically presses against the support seat 42 and the sliding seat 43. In practical applications, when the support seat 42 moves downward under the drive of the manual push-pull device 41, the left columnar spring 443 and the right columnar spring 444 are compressed and deformed by the pressure of the support seat 42, storing energy. At the same time, the sliding seat 43 moves downward under the elastic pushing force released by the left columnar spring 443 and the right columnar spring 444. The non-rigid force transmission method effectively avoids the occurrence of obvious indentation on the guide plate due to local rigid force. When the support seat 42 moves upward under the drive of the manual push-pull device 41, the left bolt assembly 441 and the right bolt assembly 442 rise with the support seat 42 and generate an upward pulling force on the sliding seat 43, enabling the sliding seat 43 to move upward. The entire lifting process is stable and controllable, providing a guarantee for subsequent precise alignment. It should also be noted that the left-mounted bolt assembly 441 and the right-mounted bolt assembly 442 have the same design structure. For the sake of brevity, only the left-mounted bolt assembly 441 will be used as an example for explanation. Figure 4 As shown, the left-side bolt assembly 441 is composed of a bolt body 4411 and a nut 4412. The bolt body 4411 passes through the bearing seat 42 and the sliding seat 43 sequentially in the vertical direction, and the outer circumferential surface of the bolt body 4411 is in clearance fit with the inner wall of the through hole of the bearing seat 42 and the sliding seat 43. The nut 4412 is threadedly connected to the lower end of the bolt body 4411 to restrict the bolt body 4411 from moving upward relative to the sliding seat 43 and to provide force support for the sliding seat 43 when it rises.
[0021] Depend on Figure 3 , 4As clearly shown, there are two guide components 45, evenly distributed along the width of the sliding seat 43. Each guide component 45 consists of a slide rail 451 and a slider 452. The slide rail 451 is fixedly mounted vertically to the frame 1. The slider 452 is fixedly connected to the back of the sliding seat 43 and slides in cooperation with the slide rail 451. In practical applications, the two guide components 45 work together to ensure that the sliding seat 43 moves smoothly along a predetermined vertical trajectory during lifting and lowering, ensuring that the straightening mold 3 can accurately approach or move away from the bearing fixture 2. This avoids uneven force during straightening due to the positional deviation of the straightening mold 3. Furthermore, the non-rigid thrust of the elastic buffer component 44 allows the force to be evenly applied to the surface of the guide plate and accurately applied to the warped parts, thereby effectively improving the correction accuracy of the warped deformation of the guide plate. To ensure uniform force transmission during calibration, avoid localized force concentration on the conductor plate, and further improve calibration accuracy, as a further optimization of the above technical solution, the area of the calibration plane must not be less than the upper surface area of the conductor plate to be calibrated, and its flatness error must not exceed 0.02mm. This allows the calibration plane to fully contact the surface of the conductor plate and works in synergy with the stable transmission of the drive unit 4 and the precise guidance of the guide component 45, providing strong support for the efficient reuse of the conductor plate. like Figure 5 As shown, the upper surface of the support fixture 2 is provided with a positioning recess 21 that matches the shape of the guide plate to be shaped. The depth of the positioning recess 21 is less than the thickness of the guide plate to be shaped; when the guide plate to be shaped is placed in the positioning recess 21, the convex part caused by its warping deformation protrudes out of the positioning recess 21.
[0022] After the guide plate is placed, the manual push-pull device 41 drives the support seat 42 to move, and the thrust is transmitted to the sliding seat 43 through the elastic buffer component 44. The sliding seat 43 drives the straightening mold 3 to perform a lifting and lowering movement to approach the support fixture 2. The straightening plane of the straightening mold 3 contacts and presses against the warped part of the guide plate protruding from the positioning recess 21. Moreover, the elastic buffer component 44 ensures that the thrust received by the sliding seat 43 is a non-rigid force. Furthermore, the manual push-pull device 41 can precisely control the straightening force and the lifting and lowering speed of the straightening mold 3 through manual operation. When dealing with a slightly warped guide plate, the force can be appropriately reduced and the speed slowed down for fine correction. When dealing with a severely warped guide plate, the parameters can be adjusted appropriately to ensure the correction effect. In this way, not only is the straightening accuracy steadily improved, but the needs of guide plates with different degrees of warping are also effectively adapted, ultimately realizing the efficient reuse of the guide plate and reducing its production and manufacturing costs.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
