Description

Technical Field

[0001] The invention relates to a special-shaped IR LED shaping tool for a remote controller, which is suitable for shaping pins of DIP special-shaped IR LED components in PCBA assembly in the remote controller production industry. Background Art

[0002] A remote control is a device used to remotely control machinery. It is mainly composed of an integrated circuit board and buttons for generating different messages. The main component of the transmitter part of the remote control is an infrared light-emitting diode, or IR LED, which is a near-infrared light-emitting device that converts electrical energy into light energy. The volume of a remote control is generally small, and a variety of components need to be installed in a limited volume. Therefore, some components need to be shaped before installation. However, IR LED has two relatively long pins, which makes it inconvenient to install directly. The pins need to be bent and shaped to the required angle. At present, existing shaping equipment, such as: tape shaping machine, separation component shaping machine, etc., can only meet the needs of vertical shaping and pin cutting, but cannot complete horizontal angle shaping. Manual shaping is required, and the accuracy and quality of manual shaping cannot be guaranteed, which cannot meet the requirements of special product use. Summary of the invention

[0003] The technical problem to be solved by the present invention is: in order to overcome the deficiencies in the prior art, the present invention provides a special-shaped IR LED shaping tool for a remote controller.

[0004] The technical solution adopted by the present invention to solve its technical problem is: a special-shaped IR LED shaping tool for a remote control, wherein two pins of the special-shaped IR LED form a symmetrical bending structure on the same side of the special-shaped IR LED along an axial section thereof, and the initial extension direction of the pins of the special-shaped IR LED is parallel to the axis of the special-shaped IR LED, and the bending structure includes a first bending portion, a second bending portion and a third bending portion which are sequentially connected and gradually move away from the axis of the special-shaped IR LED, wherein the first bending portion is perpendicular to the axis; the second bending portion is perpendicular to the axial section, and the second bending portion extends in a direction away from the axial section, and the second bending portions of the two pins have opposite bending directions but do not cross; the third bending portion is parallel to the first bending portion, and has the same extension direction.

[0005] Since the pin bending structure of the special-shaped IR LED has been determined, the shaping tooling needs to match it. Specifically, the shaping tooling includes a carrier, a primary shaping base, a secondary shaping fixing module and a leg separation assembly. The primary shaping base and the secondary shaping fixing module are relatively arranged on the carrier, and the primary shaping base is fixedly connected to the carrier, and the secondary shaping fixing module can reciprocate back and forth relative to the carrier. At least one forming cavity with the same shape as the bending structure is provided on the side opposite to the primary shaping base and the secondary shaping fixing module, and a first boss matching the number and position of the forming cavities is provided on the side opposite to the forming cavity of the secondary shaping fixing module, and the first boss cooperates with the forming cavity to form a second bending portion and a third bending portion, and an insert accommodating cavity is provided in the secondary shaping fixing module at the position of each boss, and a leg separation assembly for separating the pins is provided in the insert accommodating cavity.

[0006] Further, the leg assembly includes a primary leg fixing inner insert, a spring and a telescopic rod, the primary leg fixing inner insert being embedded in the insert accommodating cavity of the secondary shaping and fixing module and being able to telescope in and out of the insert accommodating cavity; two second parallel bosses are provided on the side opposite to the forming cavity of the primary leg fixing inner insert, the second boss being able to be embedded in the forming cavity for forming the first bending portion; a third boss for separating the pins to the left and right is provided on the bottom surface of the primary leg fixing inner insert, the third boss being V-shaped or approximately V-shaped as a whole and with the tip facing forward; one end of the telescopic rod passes through the side wall of the insert accommodating cavity with its back to the primary leg fixing inner insert, extends outward to the outside of the secondary shaping and fixing module, and is slidably connected to the secondary shaping and fixing module, and a limit stop is provided at the end of the telescopic rod extending out of the insert accommodating cavity; the other end of the telescopic rod is fixedly connected to the primary leg fixing inner insert, and the spring is sleeved on the telescopic rod between the primary leg fixing inner insert and the side wall of the insert accommodating cavity. It can generate an outward elastic force on the primary leg fixing inner insert, one end of the spring abuts against the primary leg fixing inner insert, and the other end can abut against the inner side wall of the insert accommodating cavity.

[0007] Furthermore, in order to keep the position of the secondary shaping fixing module stable when it slides back and forth on the carrier plate, it also includes two positioning sliding cover plates, which are arranged on the left and right sides of the secondary shaping fixing module and fixedly connected to the carrier plate at the bottom. A sliding groove is provided at the bottom of the inner side of the positioning sliding cover plate, and the two ends of the secondary shaping fixing module are respectively slidably connected in the sliding grooves of the left and right positioning sliding cover plates.

[0008] Furthermore, in order to realize automatic control of the shaping tooling, the control component includes a dual-axis dual-way cylinder, a solenoid valve, two current limiting adjustment elements and two touch button switches. The two touch button switches are connected in series in the power supply circuit of the solenoid valve coil, and the air source is connected to the dual-axis dual-way cylinder through the solenoid valve through a pipeline. The two current limiting adjustment elements are respectively connected to the pipeline between the solenoid valve and the dual-axis dual-way cylinder. By pressing the two touch button switches at the same time, the solenoid valve is energized, and the air source enters the dual-axis dual-way cylinder to drive the secondary shaping fixing module. The secondary shaping fixing module cooperates with the spring and the telescopic rod to push the primary leg fixing inner insert to cooperate with the primary shaping base to complete the leg separation and two 90° bending shaping.

[0009] Preferably, in order to ensure the operational strength of the tooling, the various components of the shaping tooling are made of iron or steel.

[0010] The beneficial effects of the present invention are as follows: the present invention provides a special-shaped IR LED shaping tool for a remote control, which, on the basis of the original shaping, separates the pins horizontally to the left and right and presses them to 90°, and folds out the plug-in pins, thereby solving the horizontal angle shaping method that cannot be completed by the existing shaping machine, reducing the cost loss caused by manual shaping by 80%, and solving the conflict problem of the component pins and buttons on the PCB position in product design.

DETAILED DESCRIPTION

[0021] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams that illustrate the basic structure of the present invention in a schematic manner only, and therefore only show the components related to the present invention, and directions and references (e.g., up, down, left, right, front, back, etc.) may only be used to help describe the features in the drawings. Therefore, the following specific embodiments are not to be taken in a limiting sense, and the scope of the subject matter claimed is limited only by the attached claims and their equivalents.

[0022] like Figure 1 The structure of the special-shaped IR LED 1 involved in the present invention is shown. The special-shaped IR LED 1 is used for a remote control, and its two pins form a symmetrical bending structure on the same side of the special-shaped IR LED 1 along an axial section thereof. In this embodiment, the initial extension direction of the pin of the special-shaped IR LED 1 is parallel to the axis of the special-shaped IR LED 1, and the bending structure includes a first bending portion 1a, a second bending portion 1b and a third bending portion 1c which are sequentially connected and gradually move away from the axis of the special-shaped IR LED 1, wherein the first bending portion 1a is perpendicular to the axis; the second bending portion 1b is perpendicular to the axial section, and the second bending portion 1b extends in a direction away from the axial section, and the second bending portions 1b of the two pins have opposite bending directions but do not cross; the third bending portion 1c is parallel to the first bending portion 1a, and extends in the same direction. Figure 1 The pin shaping process is shown in FIG.

[0023] like Figure 2-Figure 6 As shown, in order to form Figure 1The special-shaped IR LED 1 structure shown in the figure, the present invention provides a special-shaped IR LED 1 shaping tool, the shaping tool comprises a carrier plate 2, a primary shaping base 3, a secondary shaping fixing module 4, a positioning sliding cover plate 8 and a leg assembly; the tool can shape at least one special-shaped IR LED 1 at a time, and in this embodiment, the structure and principle of the shaping tool are explained by taking the simultaneous shaping of four special-shaped IR LEDs 1 as an example, wherein the positioning sliding cover plate 8 is two pieces, the primary leg fixing inner insert 5 is four pieces, the spring 6 is four, and a number of screws 9 of different specifications can be selected as needed. All parts are made of iron and steel.

[0024] The primary shaping base 3 and the secondary shaping fixing module 4 are arranged on the carrier plate 2 relatively to each other, and the primary shaping base 3 is fixedly connected to the carrier plate 2 by screws 9, and the secondary shaping fixing module 4 can reciprocate back and forth relative to the carrier plate 2. Four forming cavities 31 having the same shape as the bending structure are arranged on the side opposite to the primary shaping base 3 and the secondary shaping fixing module 4. The shape of the forming cavity 31 is as follows: Figure 3 As shown, it includes a first bending portion forming cavity 31a, a second bending portion forming cavity 31b and a third bending portion forming cavity 31c, which are used to form the first bending portion 1a, the second bending portion 1b and the third bending portion 1c respectively. A tongue 31d is formed between the first bending portion forming cavities 31a on both sides, and the width of the tongue 31d matches the width between the two pins. Figure 4 As shown, a first boss 41 matching the number and position of the molding cavity 31 is provided on the side of the secondary shaping and fixing module 4 opposite to the molding cavity 31, and the first boss 41 cooperates with the molding cavity 31 to form the second bending portion 1b and the third bending portion 1c, and an insert accommodating cavity 42 (shown by the dotted line in the figure) is provided in the secondary shaping and fixing module 4 at each position of the boss, and a leg separation component for separating the pins is provided in the insert accommodating cavity 42; the positioning sliding cover plate 8 is arranged on the left and right sides of the secondary shaping and fixing module 4, and the bottom is fixedly connected to the carrier plate 2 by screws 9, a slide groove 81 is provided at the bottom of the inner side of the positioning sliding cover plate 8, and slides 43 matching the slide groove 81 are provided at the left and right ends of the secondary shaping and fixing module 4, and the slide 43 of the secondary shaping and fixing module 4 extends into the interior of the slide groove 81, and the two ends of the secondary shaping and fixing module 4 are respectively slidably connected in the slide grooves 81 of the left and right positioning sliding cover plates 8 through the slide 43. The cooperation between the slide 43 and the slide groove 81 has a positioning and limiting function, which can ensure that the secondary shaping and fixing module 4 is stable during the reciprocating motion, and can ensure that the first boss 41 accurately enters the molding cavity 31.

[0025] like Figure 2As shown, the leg assembly includes a primary leg fixing inner insert 5, a spring 6 and a telescopic rod 7. The primary leg fixing inner insert 5 is embedded in the insert accommodating cavity 42 of the secondary shaping and fixing module 4 and can be telescoped in and out of the insert accommodating cavity 42; Figure 5 and Figure 6 As shown, two second parallel bosses 51 are provided on the side opposite to the molding cavity 31 of the one-time split leg fixing inner insert 5, and the second bosses 51 can be embedded in the first bending portion molding cavity 31a of the molding cavity 31 for molding the first bending portion 1a. The second bosses 51 form a U-shaped structure, and a groove 54 is formed between the second bosses 51 on both sides, and the groove 54 matches the tongue 31d of the molding cavity 31, and the tongue 31d can be inserted into the groove 54; a third boss 52 for separating the pins to the left and right is provided on the bottom surface of the one-time split leg fixing inner insert 5, and the third boss 52 is V-shaped or approximately V-shaped as a whole and the tip is facing forward. During the forward movement of the one-time split leg fixing inner insert 5, the two pins of the LED are separated to the left and right through the V-shaped surface to meet the needs of subsequent molding; a threaded hole 53 for connecting with the telescopic rod 7 is also provided on the side opposite to the second boss 51. One end of the telescopic rod 7 passes through the side wall of the insert accommodating cavity 42, extends outward to the outside of the secondary shaping fixing module 4, and is slidably connected to the through hole 44 on the secondary shaping fixing module 4. The end of the telescopic rod 7 extending out of the insert accommodating cavity 42 is provided with a limit stop 71; the other end of the telescopic rod 7 is fixedly connected to the primary split leg fixed inner insert 5, and the spring 6 is sleeved on the telescopic rod 7 between the primary split leg fixed inner insert 5 and the side wall of the insert accommodating cavity 42. Since the telescopic rod 7 needs to be connected to the primary split leg fixed inner insert 5, it is preferably possible to use a long screw, one end of which is threadedly connected to the threaded hole of the primary split leg fixed inner insert 5, and the other end serves as a limit stop 71. It can generate an outward elastic force on the primary leg fixing inner insert 5. One end of the spring 6 is against the primary leg fixing inner insert 5, and the other end can be against the inner wall of the insert accommodating cavity 42. During shaping, the primary leg fixing inner insert 5 is pressed into the molding cavity 31. At this time, due to the force, the spring 6 is compressed to generate elastic force. At the same time, the telescopic rod 7 extends out of the through hole 44. When the shaping is completed, the cylinder drives the secondary shaping fixed module 4 to retract. Due to the action of the spring 6, the primary leg fixing inner insert 5 will also stay in the molding cavity 31 for a period of time. When it is retracted to a certain position, the limit stopper 71 of the telescopic rod 7 is stuck on the secondary shaping fixed module 4, which drives the primary leg fixing inner insert 5 to retreat. On the other hand, due to the buffering effect of the spring 6, the rigid collision between the primary shaping base 3 and the secondary shaping fixed module 4 in the initial stage of shaping is avoided.

[0026] In order to realize the automatic control of the shaping tool, it also includes control components, such as Figure 7As shown, the control component includes a dual-axis dual-way cylinder 10, a solenoid valve G1, two current limiting adjustment elements 11 and two touch button switches K2 and K3. The touch button switches K2 and K3 are connected in series in the power supply circuit of the solenoid valve G1 coil. The working power supply of the solenoid valve G1 is AC220V. The power input end may also be provided with a power switch K1. The air source is connected to the dual-axis dual-way cylinder 10 through a pipeline through the solenoid valve G1 to provide an air source for the dual-axis dual-way cylinder 10 to work. In this embodiment, the air source pressure is greater than 6kPa. The two current limiting adjustment elements 11 are respectively connected to the pipeline between the solenoid valve G1 and the dual-axis dual-way cylinder 10 to control the gas flow entering the dual-axis dual-way cylinder 10. In this embodiment, the two current limiting adjustment elements 11 are connected to the air source inlet of the dual-axis dual-way cylinder 10. When working, by pressing two touch button switches K2 and K3 at the same time, the electromagnetic valve G1 is energized, and the air source enters the double-axis double-pass air cylinder 10 to drive the secondary shaping fixing module 4. The secondary shaping fixing module 4 cooperates with the spring 6 and the telescopic rod 7 to push the primary leg fixing inner insert 5 to cooperate with the primary shaping base 3 to complete the leg splitting and two 90° bending shaping. The connection relationship of each structure in the control component can be realized by the existing method, and it is sufficient to drive the secondary shaping fixing module 4 to move. Since it is not the focus of this embodiment, it will not be described in detail.

[0027] The present invention fixes the primary foot fixing insert 5 by the secondary shaping fixing module 4, and controls the retraction and ejection of the primary foot fixing insert 5 by the spring 6, completes two shapings by one action, and performs special-shaped shaping on the IR LED pin. By pressing two touch switches at the same time, the solenoid valve is energized, and the air source enters the double-axis double-pass air cylinder 10 to drive the secondary shaping fixing module 4 to realize automatic shaping.

[0028] Working principle:

[0029] like Figure 8 The figure shows the action process of the pin shaping tooling: In order to make it easier to see the action process of the internal insert, the various components in the figure are displayed in a perspective state. Among them, from figure a to figure b, the secondary shaping fixing module 4 moves toward the primary shaping base 3 until the first boss 41 and the second boss 51 enter the molding cavity 31 for shaping; from figure b to figure c, the secondary shaping fixing module 4 gradually moves away from the primary shaping base 3 until it separates to the initial position.

[0030] Processing process: put the IR LED pin toward the primary shaping base 3, the pin pointing toward the middle of the primary leg fixing inner insert 5, into the primary shaping base 3, press the two touch button switches on the box with both hands, the solenoid valve is energized to make the double-axis cylinder positively inflated, push the secondary shaping fixing module 4 and the primary leg fixing inner insert 5 to move horizontally toward the primary shaping base 3, the primary leg fixing inner insert 5 separates the two legs of the IR LED to the left and right until it is close to 90°, the second boss 51 is pushed into the molding cavity 31 of the primary shaping base 3, the IR LED pin position is limited and stops moving, the maximum point of the IR LED two legs will exceed the width of the primary leg fixing inner insert 5, the secondary shaping fixing module 4 continues to move, and at the same time the spring 6 is compressed, and the telescopic rod 7 is extended, so that the molding cavity 31 of the primary shaping base 3 and the first boss 41 of the secondary shaping fixing module 4 cooperate to squeeze the tail ends of the two legs of the IR LED into 90°.

[0031] Reset process: release the two touch button switches with both hands, the solenoid valve loses power, causing the double-axis cylinder to inflate and contract in the opposite direction, pulling back the secondary shaping fixed module 4, the spring 6 extends, the telescopic rod 7 retracts and drives the primary leg fixing inner insert 5 to move horizontally in the opposite direction to that during shaping, the cylinder retracts into place, the secondary shaping fixed module 4 and the primary leg fixing inner insert 5 are reset, and the product is taken out manually.
