Description

Technical Field

[0001] The invention belongs to the technical field of diode clamping and fixing mechanisms, and in particular relates to a dynamic clamp for light emitting diode packaging. Background Art

[0002] Light-emitting diodes, or LEDs for short, are commonly used light-emitting devices that emit light by releasing energy through the recombination of electrons and holes. They are widely used in the field of lighting. Like ordinary diodes, light-emitting diodes are composed of a PN junction and also have unidirectional conductivity. When a forward voltage is applied to a light-emitting diode, holes injected from the P region into the N region and electrons injected from the N region into the P region recombine with electrons in the N region and holes in the P region within a few microns near the PN junction, respectively, to produce spontaneously radiated fluorescence.

[0003] Light-emitting diodes are referred to as LEDs. They are made of compounds containing gallium, arsenic, phosphorus, nitrogen, etc. When electrons and holes recombine, they can radiate visible light, so they can be used to make light-emitting diodes. They are used as indicator lights in circuits and instruments, or to form text or digital displays. Gallium arsenide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and gallium nitride diodes emit blue light. Due to their chemical properties, they are divided into organic light-emitting diodes OLED and inorganic light-emitting diodes LED.

[0004] During the packaging process, the diode needs to be welded to the circuit board. On the one hand, the existing clamping mechanism cannot simply clamp and fix diodes of different sizes. When subjected to horizontal pushing force, due to the lack of corresponding positioning protection components, corresponding loosening may occur. On the other hand, when the circuit board is clamped, its installation and disassembly work is also relatively inconvenient. In addition, when the lead on the diode is offset, there is generally no correction mechanism to correct its position, which affects the welding quality of subsequent welding points and is not conducive to improving product quality. Summary of the invention

[0005] The purpose of the present invention is to provide a dynamic clamp for light-emitting diode packaging to solve the technical problems that diodes of different sizes cannot be simply clamped and fixed, and when subjected to horizontal driving force, corresponding loosening may occur due to the lack of corresponding positioning protection components, and the installation and disassembly of the circuit board when clamped is also inconvenient.

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Reference Manual Attached Figure 1 and Figure 2 As shown, a dynamic fixture for light emitting diode packaging includes:

[0037] A base plate 1 is provided with a first motor 2 fixedly mounted on the base plate 1, and an output shaft of the first motor 2 extends to a reciprocating screw 3. An outer wall edge of the reciprocating screw 3 is connected with a strip groove along the length direction of the side wall of the base plate 1, and a first slider 4 and a second slider 5 are spirally driven on the reciprocating screw 3 for moving in opposite directions.

[0038] A driving mechanism is provided, and after the first motor 2 is started, the positioning clamping mechanism 6 and the circuit board limiting mechanism 15 can be moved toward the center under the action of the spiral transmission, so that the diode and the circuit board move toward the center synchronously, thereby facilitating the subsequent welding work and improving the work efficiency.

[0039] The positioning and clamping mechanism 6 comprises a support frame placed on the first slider 4, and a second motor 7 and a first fixing ring 8 are fixedly installed on both sides of the top of the support frame, and the output shaft of the second motor 7 extends to the turntable 9. The protrusions around the turntable 9 and the movable block 10 are connected by a swing rod 11, and the outer wall of the movable block 10 is provided with a limiting groove placed on the first fixing ring 8;

[0040] Among them, both sides of the swing rod 11 are installed on the turntable 9 and the movable block 10 by a rotating connection. A clamping part 12 is fixedly installed on one side of the horizontally arranged movable block 10, and a retaining ring 13 is connected to one end of the vertically arranged movable block 10 close to the clamping part 12, and a positioning plate 14 is fixedly installed on the other end.

[0041] After the first motor 2 is started, it can drive the reciprocating screw 3 to rotate, which can drive the first slider 4 and the second slider 5 to move synchronously in the opposite direction, so that the diode on the positioning clamping mechanism 6 and the circuit board on the circuit board limiting mechanism 15 can achieve precise docking, thereby facilitating the welding operation of the welder 25.

[0042] The strip groove on the bottom plate 1 provides a movable space for the movement of the first slider 4 and the second slider 5, and the roller 42 on the first slider 4 connected by the support frame can provide friction for the movement of the first slider 4. Under the action of rolling friction, a part of the sliding friction is replaced, which can effectively reduce friction damage and increase the service life of the device.

[0043] refer to Figure 1 , Figure 3 and Figure 6 , the circuit board limiting mechanism 15, the circuit board limiting mechanism 15 includes a fixed plate on the second slider 5, a rectangular frame 16 is connected to the fixed plate by a bolt assembly, a card slot connected to the circuit board is opened on one side of the rectangular frame 16, and the circuit board limiting mechanism 15 is used to clamp and fix the circuit board.

[0044] Positioning grooves 17 are provided at the top and both sides of the outer wall of the rectangular frame 16, and the positioning grooves 17 are respectively connected with longitudinal plug rods 18 and transverse plug rods 19 that match them. The longitudinal plug rods 18 and transverse plug rods 19 are both T-shaped, and a through hole penetrating the interior of the rectangular frame 16 is provided at the center.

[0045] A circuit board limiting mechanism 15 is provided. When the circuit board is installed and fixed, the circuit board can be placed in the card slot of the rectangular frame 16 first, and then the longitudinal insertion rod 18 and the transverse insertion rod 19 are placed in the positioning slot 17, so as to limit the circuit board on all sides. Since the longitudinal insertion rod 18 and the transverse insertion rod 19 are both T-shaped, it is convenient for personnel to take out and insert them into the positioning slot 17. Secondly, when the circuit board is taken out, it is inserted into the through hole through the resistance piece, so that the circuit board is pushed out by contact and fitting, which is convenient for personnel to operate and greatly improves work efficiency.

[0046] Specifically, the rectangular frame 16 is provided with positioning grooves 17 through the top and both sides of the outer wall, thereby forming corresponding longitudinal slots and transverse slots, and then the longitudinal insertion rods 18 and the transverse insertion rods 19 are inserted into the positioning grooves 17, so as to block and limit the outer walls of the circuit board all around, which has a good limiting and fixing effect, and when taking it out, it only needs to cooperate with the insertion of the resistance piece in the through hole to directly push the circuit board out.

[0047] refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 A clamping portion 12 is fixedly installed on one side of the horizontally arranged movable block 10, and a retaining ring 13 is connected to one end of the vertically arranged movable block 10 near the clamping portion 12. That is to say, the clamping portion 12 cooperates with the positioning plate 14 on the movable block 10, which not only has the effect of clamping and fixing the diode, but also can block and position its side wall, so that the diode will not be separated or loosened during the contact and bonding process of the circuit board, and an L-shaped baffle is directly arranged on the clamping portion 12 relative to the surrounding areas. Through the horizontal and vertical structural matching connection, it can not only play a positioning protection role, but also help save material costs and reduce production costs.

[0048] A positioning and clamping mechanism 6 is provided. After the second motor 7 is started, the rotating disk 9 can be rotated, and then the rotating connection setting of the swing rod 11 can be used to make the movable blocks 10 on the surrounding sides move synchronously in the center. When the movable block 10 moves in the center, the diode can be clamped in the center by the clamping part 12. In addition, the positioning plate 14 can be driven to achieve the shielding and protection of the side wall of the diode. In this way, even if the diode collides with the circuit board and generates an external force, the diode will not become loose. The diode can be effectively positioned and protected in a comprehensive manner, and diodes of different sizes can also be adaptively clamped and fixed, with a good positioning effect.

[0049] refer to Figure 3 , Figure 7 and Figure 8A dynamic fixture for light-emitting diode packaging also includes a welding mechanism 20 between the positioning clamping mechanism 6 and the circuit board limiting mechanism 15, the welding mechanism 20 includes a third motor 21 placed on the base plate 1, the output shaft of the third motor 21 is connected to a first rotating tooth 22, the outer wall of the first rotating tooth 22 is meshed and driven with a second rotating tooth 24 movably connected to a second fixing ring 23, one end of the second rotating tooth 24 is provided with a rolling groove along the outer wall edge of the second fixing ring 23, the second fixing ring 23 is fixed to the base plate 1 by a bracket, and both sides of the outer wall of the second rotating tooth 24 are fixedly installed with a welder 25 with an opening facing one side of the circuit board and tilted. As the third motor 21 is started, the second rotating tooth 24 drives the welder 25 to perform annular welding between the diode lead and the soldering point position on the circuit board.

[0050] A correction component 26 is detachably mounted on the inner wall of the second fixing ring 23. The correction component 26 includes a first telescopic rod 27. The first telescopic rods 27 are connected by a guide block 28, and guide holes 29 connected to the diode leads are provided on both sides of the guide block 28. One end of the first telescopic rod 27 is connected to the socket of the second fixing ring 23 by plugging.

[0051] A deviation correction component 26 is provided, and a detachably connected guide block 28 is provided on the positioning and clamping mechanism 6. When the lead wire on the diode deviates at a certain angle, the positioning and clamping mechanism 6 cooperates with the first motor 2 to drive the diode to move back and forth, so that the lead wire on the diode reciprocates through the guide hole 29 on the guide block 28, thereby having a position correction effect and improving the quality of subsequent welding.

[0052] When the positions of the two leads on the diode do not need to be corrected, the correction component 26 does not need to be connected to the second fixing ring 23. When the two leads on the diode deviate in angle, that is, the leads cannot be maintained in the corresponding horizontal state, at this time, when the positioning clamping mechanism 6 drives the diode to move, the leads on the diode will pass back and forth through the guide holes 29 in the guide block 28, thereby helping the leads to return to a horizontal position. When removing the guide block 28, it is only necessary to center and stretch the first telescopic rod 27 to disengage the first telescopic rod 27 from the socket of the second fixing ring 23, so that the two can be separated.

[0053] Specifically, the second fixing ring 23 and the positioning clamping mechanism 6 are connected through a guide buffer assembly 30, and the guide buffer assembly 30 includes a pull rod 32 telescopically connected to the inner wall of the sleeve 31, and the outer wall of the pull rod 32 is integrally formed with a tapered portion 33, and the side wall of the sleeve 31 is provided with a tapered surface 34 that is in contact with the tapered portion 33 near the movable opening, and an elastic resistance ball 35 is provided on the side wall of the sleeve 31 between the tapered portion 33 and the tapered surface 34.

[0054] A buffer rod 36 is telescopically connected at the center of the side wall of the sleeve 31, and both sides of the buffer rod 36 are connected to the extrusion plate 38 through a rotating frame 37. One end of the extrusion plate 38 is movably connected to the second telescopic rod 39. A fixed rod 40 fixed to the side wall of the sleeve 31 is provided at the center of the rotating frame 37, and both ends of the rotating frame 37 are correspondingly rotatably connected to the extrusion plate 38 and the buffer rod 36 through a movable shaft. A buffer pad 41 is installed on one end of the buffer rod 36 near the pull rod 32, and the other end is telescopically connected to the lateral extension portion on the side wall of the sleeve 31, and a gap is formed between the buffer rod 36 and the lateral extension portion.

[0055] When the pull rod 32 moves toward the second fixed ring 23, the elastic resistance ball 35 and the tapered surface 34 on the side wall of the sleeve 31 can provide corresponding resistance and increase the contact area, thereby achieving the effect of unloading force and avoiding excessive concentration of force, so that the pull rod 32 can smoothly translate on the inner wall of the sleeve 31. In addition, when the pull rod 32 moves toward the first fixed ring 8, the pull rod 32 first contacts and connects with the extrusion plates 38 at both ends of the second telescopic rod 39, and pushes the extrusion plates 38 to move toward the second telescopic rod 39. Under the rotation of the rotating frame 37 on the fixed rod 40, the buffer rod 36 can be pulled toward the pull rod 32, and then the extrusion force of the pull rod 32 is converted into the mechanical energy of the buffer rod 36, and the buffer pad 41 on the buffer rod 36 is driven to contact the pull rod 32 to limit the position, thereby forming a situation where the applied force is offset, thereby preventing the force brought by the pull rod 32 from being too large, thereby causing collision damage to the structural parts.

[0056] A guide buffer component 30 is provided. When the positioning clamping mechanism 6 moves, the sleeve 31 cooperates with the pull rod 32 to effectively guide it to move, thereby preventing position deviation during movement, and effectively making the diode and the solder joints on the circuit board accurately docked. In addition, in order to prevent the pull rod 32 from exerting excessive force during movement, a corresponding buffer component is provided to disperse the applied force through elastic blocking, contact surface expansion and energy transfer conversion to avoid excessive concentration of force, thereby greatly improving the safety of the device.

[0057] Both sides of the bottom end of the support frame are movably connected with rollers 42 placed on the base plate 1, and the rollers 42 are connected with rolling tracks along the length direction of the base plate 1. A positioning hole is opened at the connection between the second slider 5 and the fixed plate and they are connected by locking and fixing with a stop pin. The connection by locking and fixing with a stop pin is conducive to the installation and disassembly work between the structural parts and convenient for personnel to operate.
