[0003] Chinese Invention Publication No.: CN116111031B discloses an LED chip packaging and welding device, comprising a housing mechanism and a driving mechanism. The driving mechanism is installed on one side of the outer wall of the housing mechanism. A moving mechanism is installed on one side of the driving mechanism and drives the moving mechanism to rotate. A heater is fixed at the bottom of the moving mechanism. A material placement mechanism is installed on one side of the inner wall of the housing mechanism. This invention uses a fixing mechanism to clamp and limit the LED chips, ensuring the position of the LED chip and preventing the LED chips from being pulled crooked by liquid tension during welding, thus reducing the welding defect rate. Furthermore, the LED chips are inspected by a detection mechanism before welding and removed before welding to avoid defects after welding, which would be time-consuming, laborious, and affect efficiency.

[0004] In the process of realizing this invention, the inventors discovered that the technology has at least the following problems: the operation of picking up, inspecting and welding LED beads is too cumbersome and cannot properly pick up and process the LED beads for welding, thus affecting work efficiency. Therefore, an LED bead packaging and welding device is now proposed. Summary of the Invention

[0005] To address the issue of low efficiency in packaging and welding equipment, this invention provides an LED bead packaging and welding device.

[0006] This invention provides an LED chip packaging and welding equipment, which adopts the following technical solution:

[0007] An LED bead packaging and welding device includes a processing box, characterized in that the processing box has limiting plates at all four corners of its top, and a placement mechanism is provided inside the processing box. A detection mechanism is installed on one side of the limiting plates at the top of the processing box, and two slide rails are fixed on each side of the inner wall of the processing box. A fixing plate is provided below each slide rail on the inner wall of the processing box, and an electric push rod is embedded at the top of the fixing plate. A welding mechanism is provided between the placement mechanism and the fixing plate inside the processing box, and a reserved groove is provided between the slide rail and the placement mechanism.

[0008] By adopting the above technical solution, and using a separate placement mechanism placed on the testing mechanism, defective LED beads can be removed while testing is being performed.

[0009] Optionally, the mounting mechanism includes a sliding plate, which is slidably connected inside the slide rail, and a support plate is fixedly installed at one end of the sliding plate that extends out of the slide rail. The top of the support plate has multiple sets of mounting holes, and limit blocks are fixedly installed on both sides inside the mounting holes.

[0010] By adopting the above technical solution, the sliding plate and slide rail facilitate the placement mechanism to enter the processing box and be supported.

[0011] Optionally, the placement mechanism further includes a through hole, which is opened on one side of the limiting block inside the placement hole. A threaded rod is inserted into the front end of the support plate, and one end of the threaded rod that passes through the support plate passes through the push plate. Multiple sets of support rods are evenly fixed on one side of the outer wall of the push plate, and sliders are fixedly installed on both sides of the bottom end of the push plate. Multiple sets of connecting plates are evenly connected to the outer wall of the support rods, and clamping blocks are fixedly installed on the outer wall side of the connecting plates away from the support rods.

[0012] By adopting the above technical solution, the rotation of the threaded rod drives the push plate, which in turn drives the support rod to drive the connecting plate, allowing the clamping block to pass through the through hole to clamp and fix the lamp bead.

[0013] Optionally, the threaded rod is threadedly connected to the push plate, and the push plate forms a sliding structure with the support plate through the slider.

[0014] By adopting the above technical solution, the threaded connection between the threaded rod and the push plate facilitates the movement of the push plate by turning the threaded rod.

[0015] Optionally, the testing mechanism includes a support platform, which is fixedly installed between four limiting plates at the top of the processing box. Damping springs are fixedly installed at the four corners of the top of the support platform. Testing points are embedded at the positions corresponding to the mounting holes at the top of the support platform, and a rubber pad is bonded to one side of the testing point at the top of the support platform.

[0016] By adopting the above technical solution, detection points are set up corresponding to the number and position of the mounting holes, which facilitates the simultaneous detection of multiple groups of LED beads to improve efficiency, and the limiting plate helps to guide the mounting mechanism to avoid deviation.

[0017] Optionally, the detection mechanism further includes a rotating shaft, which is rotatably connected to the top of two diagonally positioned limiting plates, and an adjusting plate is fixedly installed on the rotating shaft through the outer wall of the limiting plates.

[0018] By adopting the above technical solution, the adjusting plate is rotated via the rotating shaft, thereby fitting and pressing the mounting mechanism, so that the mounting mechanism presses the damping spring with a certain degree of shock absorption.

[0019] Optionally, the adjusting plate forms a rotating structure with the limiting plate via a rotating shaft, and the rotating shaft and the limiting plate form a locking structure.

[0020] By adopting the above technical solution, the adjustment plate rotates about the pivot, which facilitates the limiting of the placement mechanism and prevents it from disengaging during retesting. At the same time, after the test is completed, rotating the adjustment plate allows the placement mechanism to disengage under the elastic push of the damping spring.

[0021] Optionally, the welding mechanism includes a support plate connected to the output end of an electric push rod. The support plate has two axially opposite surfaces at the top of the support plate with limiting grooves. A placement plate is slidably connected inside the limiting grooves, and a pressing block is fixedly installed on one side of the placement plate. An assembly groove is provided at the front end of the placement plate at the top of the support plate, and a first spring is embedded inside the assembly groove. A sealing block is connected to the top of the first spring.

[0022] By adopting the above technical solution, the lamp plate is moved inside the carrier plate by the placement plate, and then pushed by the electric push rod to make the carrier plate fit into the placement mechanism, so that the lamp plate of the placement plate contacts the lamp bead pin.

[0023] Optionally, the welding mechanism further includes a connecting shell, which is fixedly installed at the end of the top of the support plate away from the assembly groove, and a second spring is embedded inside the connecting shell. A heating plate is embedded at the top of the support plate corresponding to the position of the placement plate, and pressure sensors are embedded in the outer walls of the two axially inserted pre-reserved grooves at the top of the support plate.

[0024] By adopting the above technical solution, the pressure sensor detects the contact between the carrier plate and the mounting mechanism, and then transmits the signal to the control module of the packaging and welding equipment, which controls the electric push rod to stop, thus avoiding excessive pressure that could damage the components.

[0025] Optionally, the placement plate forms a sliding structure with the support plate through the limiting groove, and the support plate forms an elastic structure with the sealing block through the first spring.

[0026] By adopting the above technical solution, the elasticity of the first spring facilitates the pushing of the sealing block out of the assembly slot, thereby limiting the placement plate and preventing shaking or displacement during welding.

[0027] In summary, the present invention has the following beneficial effects:

[0028] 1. In this invention, the support plate is placed on a table with the pins facing down and the positive and negative terminals corresponding to the positive and negative terminals of the detection mechanism. The LED bead is then placed into the mounting hole, and a limiting block initially limits its position to facilitate alignment. The pins are supported by the table. Simultaneously, the threaded rod is turned to push the push plate to move. The push plate slides along the support plate via a slider to prevent it from rotating with the threaded rod. The push plate drives the support rod, thereby pushing the connecting plate to slide towards the through hole until the clamping block passes through the through hole and presses against one side of the LED bead. This facilitates the fixing and clamping of the LED bead in the mounting hole, thus fixing and mounting multiple LED beads at the same time, avoiding the cumbersome installation of individual LED beads, which would affect processing efficiency.

[0029] 2. This invention features a support platform with detection points corresponding to the mounting holes. When the mounting mechanism is positioned above the support platform under the guidance of the limiting plate, it is elastically supported by a damping spring. Pressing the mounting mechanism causes the LED pins to fit against the support platform, and then the detection points are used for testing. Simultaneously, the adjusting plate is rotated via a rotating shaft to prevent the LED pins from separating from the detection points. If weak light or damage is detected during this process, the threaded rod can be turned to replace the LED, facilitating replacement directly during testing and improving efficiency. The thickness of the LED pins is supported by a rubber pad to prevent excessive compression that could cause the pins to bend.

[0030] 3. In this invention, after the lamp board with solder paste is placed in the placement plate, it passes through the limiting groove into the carrier plate. Then, the sealing block is pushed by the elastic first spring to press against the placement plate and the lamp board for limiting. At the same time, the pressing block fixed by the placement plate further limits the lamp board. The connecting shell fixed by the carrier plate is embedded with multiple sets of second springs. Both the first and second springs are damping and shock-absorbing springs, which clamp the placement plate to keep the lamp board stable. Then, the slide rail of the placement mechanism passes into the processing box, and the carrier plate is pushed up by the electric push rod. The carrier plate drives the placement plate to rise, so that the lamp bead pins and the lamp board solder paste come into contact. At the same time, the heating plate heats and melts the solder paste and then cools it, so that the lamp bead pins and the lamp board are soldered. Attached Figure Description

Detailed Implementation

[0041] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail.

[0042] Please refer to Figure 1-5 An LED bead packaging and welding device includes a processing box 1. Each of the four corners of the top of the processing box 1 has a limiting plate 2. An installation mechanism 3 is installed inside the processing box 1. A detection mechanism 4 is installed on one side of the limiting plate 2 at the top of the processing box 1. Two slide rails 5 are fixed on each side of the inner wall of the processing box 1. A fixing plate 6 is installed below each slide rail 5 on the inner wall of the processing box 1. An electric push rod 7 is embedded at the top of the fixing plate 6. A welding mechanism 8 is installed between the installation mechanism 3 and the fixing plate 6 inside the processing box 1. A reserved groove 9 is provided between the slide rail 5 and the installation mechanism 3. The limiting plate 2 facilitates the positioning of the installation mechanism 3, thereby driving the LED bead to contact the detection mechanism 4 for detection. After detection, the LED bead passes through the slide rail 5 into the processing box 1. Supported by the fixing plate 6, the electric push rod 7 pushes the welding mechanism 8 to close the installation mechanism 3, performing welding on the LED bead.

[0043] The placement mechanism 3 includes a slide plate 302, which is slidably connected inside the slide rail 5. A support plate 301 is fixedly installed at one end of the slide plate 302 extending out of the slide rail 5. Multiple placement holes 303 are formed at the top of the support plate 301. Limiting blocks 304 are fixedly installed on both sides of the interior of each placement hole 303. The placement mechanism 3 also includes a through hole 311, which is formed on one side of the limiting block 304 inside the placement hole 303. A threaded rod 305 is inserted into the front end of the support plate 301. One end of the threaded rod 305 passes through a push plate 307. Multiple support rods 308 are evenly fixed at equal intervals on one side of the outer wall of the push plate 307. Slider blocks 306 are fixedly installed on both sides of the bottom end of the push plate 307. Multiple connecting plates 309 are evenly connected at equal intervals to the outer wall of the support rods 308. Clamping blocks 310 are fixedly installed on the outer wall of the connecting plates 309 away from the support rods 308. The threaded rod 305 is threadedly connected to the push plate 307. The push plate 307 forms a sliding structure with the support plate 301 via the slider 306. The support plate 301 is placed on the table with the pins facing down and the positive and negative poles corresponding to the positive and negative poles of the detection mechanism 4. The LED bead is then placed into the mounting hole 303. The limiting block 304 initially limits the position to facilitate alignment, and the pins are supported by the table. At the same time, the threaded rod 305 is turned to push the push plate 307 to move. The push plate 307 slides along the support plate 301 via the slider 306 to prevent it from rotating with the threaded rod 305. The push plate 307 drives the support rod 308, thereby pushing the connecting plate 309 to slide into the through hole 311 until the clamping block 310 passes through the through hole 311 and presses against one side of the LED bead, which facilitates the fixing and clamping of the LED bead in the mounting hole 303. This allows for the simultaneous fixing and mounting of multiple LED beads, avoiding the trouble of installing individual beads and thus affecting processing efficiency.

[0044] Reference Figure 1 and Figure 6The detection mechanism 4 includes a support platform 401, which is fixedly installed between four limiting plates 2 at the top of the processing box 1. Damping springs 402 are fixedly installed at each of the four corners of the top of the support platform 401. Detection points 403 are embedded at the positions corresponding to the mounting holes 303 at the top of the support platform 401. A rubber pad 404 is bonded to one side of each detection point 403 at the top of the support platform 401. The detection mechanism 4 also includes a rotating shaft 405, which is rotatably connected to the tops of two diagonally positioned limiting plates 2. An adjusting plate 406 is fixedly installed on the rotating shaft 405 through the outer wall of the limiting plate 2. The adjusting plate 406 forms a rotating structure with the limiting plate 2 via the rotating shaft 405, and the rotating shaft 405 and the limiting plate 2 form a locking connection. The structure includes a support platform 401 with a detection point 403 corresponding to the mounting hole 303. When the mounting mechanism 3 is positioned above the support platform 401 under the guidance of the limiting plate 2, it is elastically supported by the damping spring 402. After pressing the mounting mechanism 3, the lamp bead pin is brought into contact with the support platform 401 and then detected by the detection point 403. At the same time, the adjusting plate 406 is rotated via the rotating shaft 405 to prevent the lamp bead pin from separating from the detection point 403. If weak light or damage is detected during the test, the threaded rod 305 can be turned to replace the lamp bead. This allows for direct replacement during the test, improving efficiency. The thickness of the lamp bead pin is supported by the rubber pad 404 to prevent excessive compression that could cause the pin to bend.

[0045] Reference Figure 1 , Figure 7 and Figure 8The welding mechanism 8 includes a support plate 801 connected to the output end of an electric push rod 7. A limiting groove 802 is formed on the two axially opposite surfaces of the top of the support plate 801. A placement plate 803 is slidably connected inside the limiting groove 802. A pressing block 804 is fixedly installed on one side of the placement plate 803. An assembly groove 805 is formed at the front end of the placement plate 803 at the top of the support plate 801. A first spring 806 is embedded inside the assembly groove 805, and a sealing block 807 is connected to the top of the first spring 806. The welding mechanism 8 also includes a connecting shell 808, which is fixedly installed at the end of the top of the support plate 801 away from the assembly groove 805. A second spring 809 is embedded inside the connecting shell 808. A heating plate 810 is embedded at the top of the support plate 801 corresponding to the position of the placement plate 803. Pressure sensors 811 are embedded in the outer wall of the pre-reserved groove 9 on both axial directions of the top of the support plate 801. The placement plate 803 is connected to the support plate 803 via the limiting groove 802. The carrier plates 801 form a sliding structure, and the carrier plates 801 form an elastic structure with the first spring 806 and the sealing block 807. After the lamp board with solder paste is placed in the placement plate 803, it passes through the limiting groove 802 into the carrier plate 801. Then, the sealing block 807 is pushed by the elastic first spring 806 to press against the placement plate 803 and the lamp board for limiting. At the same time, the pressing block 804 fixed to the placement plate 803 further limits the lamp board. The connecting shell 808 fixed to the carrier plate 801 is fitted with multiple sets of second springs 809. The first spring 806 and the second spring 809 are both damping and shock-absorbing springs, which clamp the placement plate 803 to keep the lamp board stable. Then, the slide rail 5 of the placement mechanism 3 passes into the processing box 1 and pushes the carrier plate 801 to rise through the electric push rod 7. The carrier plate 801 drives the placement plate 803 to rise, so that the lamp bead pins and the lamp board solder paste come into contact. At the same time, the heating plate 810 heats and melts the solder paste and then cools it, so that the lamp bead pins and the lamp board are soldered.

[0046] The implementation principle of this invention is as follows: First, the support plate 301 of the placement mechanism 3 is placed on the table. Multiple sets of placement holes 303 are opened to place the lamp beads on the table for support. The positive and negative positions of the lamp beads are adjusted and the pins are facing downwards. The limiting block 304 in the placement hole 303 facilitates the regularization of the position. At the same time, the threaded rod 305 is turned. After the threaded rod 305 passes through the support plate 301, it passes through the push plate 307 and is bolted to facilitate the push plate 307 to slide in the support plate 301. The push plate 307 passes through the reserved sliding groove in the support plate 301 through the slider 306 and engages, which facilitates the stable sliding of the push plate 307 and drives the support rod 308 to slide. The support rod 308 drives the connecting plate 309, so that the clamping block 310 passes through the through hole 311 out of the support plate 301 and presses the lamp beads in the placement hole 303, which plays a clamping and limiting role and avoids the low efficiency of one-by-one toggling installation.

[0047] The installed mounting mechanism 3 is then positioned on the support platform 401 of the testing mechanism 4 by the limiting plate 2. The mounting mechanism 3 is elastically supported by the damping spring 402. After pressing the mounting mechanism 3, the adjusting plate 406 is rotated via the rotating shaft 405 to close and tighten the mounting mechanism 3, preventing it from loosening due to the elasticity of the damping spring 402. The damping spring 402 also provides some shock absorption. The tightened mounting mechanism 3 aligns the LED bead pins with the testing point 403 on the support platform 401, allowing for LED bead testing. Faulty LEDs can be replaced by loosening the threaded rod 305, facilitating replacement during testing and improving work efficiency. A rubber pad 404 is provided on one side of the testing point 403 to prevent excessive pressure from damaging the LED bead or pins. After testing, rotating the adjusting plate 406 causes the mounting mechanism 3 to rise elastically, facilitating its removal and insertion into the processing box 1 via the slide rail 5.

[0048] Two electric push rods 7 are embedded in the fixed plate 6 welded inside the support platform 401. The electric push rods 7 push the support plate 801 of the welding mechanism 8 to cover the bottom end of the placement mechanism 3 from the bottom. The placement plate 803 passes through the limiting groove 802 into the support plate 801, and the lamp board with solder paste is placed through the placement plate 803. The placement plate 803 is initially limited by the fixed pressing block 804. Simultaneously, when the placement plate 803 passes through the limiting groove 802, the unpressurized sealing block 807 is elastically pushed out of the assembly groove 805 by the first spring 806, limiting the placement plate 803 from one side and pressing the lamp board. Multiple sets of second springs 809 are embedded in the connecting shell 808 fixed at the top of the support plate 801 on the side away from the assembly groove 805, thereby clamping the placement plate 803 to prevent shaking and thus affecting the corresponding position of the lamp board and the lamp beads. When the carrier plate 801 is pushed by the electric push rod 7, both ends of the carrier plate 801 axially enter the reserved groove 9, which facilitates the clamping of the slide plate 302 and avoids misalignment or shaking that could cause misalignment of the lamp board beads. Then, the heating plate 810 embedded in the carrier plate 801 heats the solder paste to make contact with the lamp board pins. After cooling, the soldering is performed. At the axial top of the carrier plate 801 corresponding to the slide plate 302, multiple sets of pressure sensors 811 are embedded to sense the pressure and transmit it to the control terminal of the packaging and welding equipment via the signal module. The control module controls the electric push rod 7 to avoid excessive clamping during operation, which could cause damage. Each processing box 1 is equipped with two sets of placement mechanisms 3 and welding mechanisms 8, so that while one set is heating and welding, the other set of lamp beads is placed and tested, thereby improving efficiency, avoiding inter-process correspondence, and requiring only one person to operate the production, saving manpower.

[0049] The above are all preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Therefore, all equivalent changes made in accordance with the structure, shape and principle of the present invention should be covered within the scope of protection of the present invention.
