Description

Technical Field

[0001] This invention relates to the field of LED packaging technology, and in particular to a welding and receiving machine suitable for LED brackets. Background Technology

[0002] Existing LED bracket welding production lines typically consist of a feeding mechanism, a die bonder, a receiving mechanism, a reflow oven, a receiving mechanism, and several guide tracks for the connecting mechanism.

[0003] The typical LED bracket soldering process is as follows: the unloading mechanism transports the LED bracket to the die bonder's worktable. The die bonder applies solder paste to the target position on the LED bracket and places the LED chip. Then, the unloading equipment rewinds the bracket, which takes at least 4 hours. After rewinding, the LED bracket is sent to a reflow oven to heat the solder paste for soldering. The unloading equipment then rewinds the soldered LED bracket again. This production line occupies a large area, and the reflow oven is expensive. Furthermore, the solder paste formula contains volatile components. The long interval between rewinding (at least 4 hours) and reflowing can cause some of these volatile components to evaporate, affecting the final soldering result. Summary of the Invention

[0004] To overcome the shortcomings of the prior art, the present invention provides a welding and receiving integrated machine suitable for LED brackets.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] A welding and receiving integrated machine for LED brackets includes a vertical cabinet. A receiving station is provided on the surface of the cabinet. Above the receiving station, a pulling station and a heating station are respectively located on the left and right sides. The receiving station is equipped with a receiving mechanism. Above the receiving station is a mounting box, which is divided into a pulling station and a heating station on the left and right sides. The pulling station is equipped with a pulling mechanism, and the heating station is equipped with a heating mechanism. In the material conveying direction, the displacement of the pulling mechanism in a single pull corresponds to the length of the heating area in a single heating operation. A control system is installed inside the vertical cabinet, and the receiving mechanism, pulling mechanism, and heating mechanism are respectively connected to the control system.

[0007] The heating mechanism includes a heating plate connected to a lifting power component. The mounting box has a through-hole corresponding to the upward direction of the heating plate. The lifting power component drives the heating plate to rise through the through-hole and contact the LED bracket. The lifting power component includes a support platform and a first drive motor connected to it. A heat insulation plate is provided on the support platform, and the heating plate is installed on the top surface of the heat insulation plate. The first drive motor controls the vertical lifting of the support platform.

[0008] A clamping grid and an exhaust cover are provided above the heating plate. The clamping grid is fixed on both sides of the through opening along the conveying direction. The shape of the clamping grid corresponds to the clearance of the LED bracket. An exhaust cover is provided above the heating plate. The exhaust cover includes an air inlet and an air outlet. The air inlet covers the heating plate, and the air outlet is connected to an exhaust pipe.

[0009] The mounting box has a top plate and a conveying groove adapted to the size of the LED bracket on its top surface. The conveying groove has material pulling holes through the top plate on both sides along its length. The material pulling mechanism includes a lifting clamping component and a push-pull component. The lifting clamping component is located above the conveying groove. The lifting clamping component and the push-pull component slide and engage vertically through the material pulling holes. The lifting clamping component clamps or releases the LED bracket, and the push-pull component drives the lifting clamping component to move along the length of the material pulling holes.

[0010] The conveying groove is provided with a downwardly recessed clamping groove at the position of the positioning holes on both sides of the LED bracket. The lifting clamping assembly includes a fixed block and a first lifting cylinder connected to each other. The fixed block is equipped with two inserts. The inserts have pointed tips facing the LED bracket. The distance between the pointed tips of the two inserts corresponds to the distance between the positioning holes on both sides of the LED bracket. The first lifting cylinder controls the fixed block to descend, and the pointed tips pass through the positioning holes of the LED bracket and insert into the clamping groove.

[0011] The first lifting cylinder is provided with an inverted U-shaped first mounting seat. The first mounting seat is placed on the top plate across the conveying groove and the two material pulling holes. The first mounting seat has a cavity inside to accommodate the first lifting cylinder. The fixing block is suspended above the conveying groove by connecting the first lifting cylinder. The fixing block moves up and down inside the first mounting seat.

[0012] The lifting clamping assembly is provided with two pressing blocks and a connecting rod. The two pressing blocks and the fixing block are arranged along the conveying direction. The two pressing blocks are located on both sides of the fixing block. The connecting rod horizontally connects the fixing block and the two pressing blocks. The two pressing blocks do not cover the material pulling through hole.

[0013] The push-pull assembly includes a second drive motor, a lead screw, and a transmission base. The second drive motor is connected to the lead screw, and the lead screw is connected to the transmission base. The transmission base has sliding locking pins on both sides that pass through the material pulling hole. The fixing block has locking holes adapted to the sliding locking pins. The fixing block is locked in the transmission base, and the lifting stroke of the fixing block is less than the height of the sliding locking pins.

[0014] The mounting box is equipped with a pull sensor and a reset sensor. The pull sensor is closer to the heating station than the reset sensor. The distance between the pull sensor and the reset sensor is equal to the length of the heating area of ​​the heating station. The transmission base is equipped with a sensing block that is compatible with both the pull sensor and the reset sensor.

[0015] The vertical cabinet is equipped with a start sensor and a stop sensor on the side where the heating station is located, and a start sensor and a stop sensor on the side where the material pulling station is located.

[0016] The beneficial effects of this invention are as follows: Compared with conventional welding production lines equipped with reflow ovens, this invention integrates the material pulling mechanism and heating mechanism above the material receiving mechanism, resulting in smaller equipment size and floor space, lower equipment cost, and direct connection to the die bonder to heat the solder paste in a timely manner, preventing excessive volatilization of volatile components in the solder paste before welding, optimizing the welding effect, achieving continuous welding, and effectively improving production efficiency.

[0021] In the description of this invention, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. Furthermore, in the description of this invention, "a plurality of" or "several" means two or more, unless otherwise explicitly specified.

[0022] Reference Figures 1 to 3 A welding and receiving machine suitable for LED brackets includes a vertical cabinet 1, on the surface of which a receiving station is provided, and above the receiving station, a pulling station and a heating station are respectively provided on the left and right sides.

[0023] The receiving station is equipped with a receiving mechanism, which in this embodiment is a receiving turntable. A mounting box 6 is located above the receiving station and is fixed to the vertical cabinet 1. The mounting box 6 is divided into a pulling station and a heating station. The pulling station is equipped with a pulling mechanism, and the heating station is equipped with a heating mechanism. In the material conveying direction, the displacement of the pulling mechanism in a single pull corresponds to the length of the heating area in a single heating operation.

[0024] The vertical cabinet 1 is equipped with a control system, and the material receiving mechanism, material pulling mechanism and heating mechanism are respectively connected to the control system.

[0025] The heating mechanism includes a heating plate 24, which is connected to a lifting power assembly. The mounting box 6 has a through-hole 21 corresponding to the upward direction of the heating plate 24. The lifting power assembly drives the heating plate 24 to rise, pass through the through-hole 21, and contact the LED bracket to heat and melt the solder paste. The lifting power assembly is controlled by the control system.

[0026] In this embodiment, the lifting power assembly includes a support platform 31 and a first drive motor 30 connected to each other. The first drive motor 30 is controlled by a control system. A heat insulation plate 29 is provided on the support platform 31 (to reduce unnecessary travel of the heating plate 24 and to ensure heat insulation effect, two heat insulation plates 29 are used in this embodiment). The heating plate 24 is mounted on the top surface of the heat insulation plate 29. The heat insulation plate 29 can minimize heat dissipation from the bottom of the heating plate 24, and at the same time reduce the impact of the high temperature generated by the heating plate 24 on the lifespan of the first drive motor 30. The first drive motor 30 controls the lifting of the heating plate 24 by controlling the vertical lifting of the support platform 31.

[0027] A clamping grid 16 is provided above the heating plate 24. The clamping grid 16 is fixed on both sides of the through-hole 21 along the conveying direction, and the shape of the clamping grid 16 corresponds to the clearance position of the LED bracket. When the heating plate 24 rises to heat and melt the solder paste on the LED bracket, the clamping grid 16 can cooperate with the heating plate 24 to clamp the LED bracket, preventing the LED bracket from bending or tilting upwards, ensuring the contact area between the LED bracket and the heating plate 24, and thus ensuring the final soldering effect between the LED bracket and the LED chip.

[0028] An exhaust cover 12 is provided above the heating plate 24 to minimize heat dissipation and prevent dust and other contaminants from adhering to the melted solder paste. The exhaust cover 12 includes an air inlet and an air outlet. The air inlet covers the heating plate 24, and the air outlet is connected to an exhaust pipe to promptly discharge the volatiles generated after the solder paste is heated.

[0029] The heating time and temperature in this embodiment can be set and adjusted according to the specific product requirements.

[0030] The top surface of the mounting box 6 is provided with a top plate and a conveying groove 20 adapted to the size of the LED bracket. The conveying groove 20 is provided with a downwardly recessed clamping groove 19 at the position of the positioning holes on both sides of the LED bracket. The two sides of the conveying groove 20 are respectively provided with a material pulling through hole 18 that penetrates the top plate along the length direction.

[0031] The material pulling mechanism includes a lifting clamping assembly and a push-pull assembly. The lifting clamping assembly is disposed above the conveying groove 20. The lifting clamping assembly and the push-pull assembly pass through the material pulling through hole 18 and form a sliding engagement in the vertical direction. The lifting clamping assembly is used to clamp or release the LED bracket. The push-pull assembly drives the lifting clamping assembly to perform the material pulling process along the length direction of the material pulling through hole 18.

[0032] The lifting and clamping assembly includes a fixed block 15 and a first lifting cylinder connected to each other. The fixed block 15 is equipped with two inserts 17, each with a pointed tip facing the LED bracket. The distance between the tips of the two inserts 17 corresponds to the distance between the positioning holes on both sides of the LED bracket. The first lifting cylinder controls the fixed block 15 to descend, and the pointed tips pass through the positioning holes of the LED bracket and insert into the clamping groove 19, thus completing the clamping of the LED bracket.

[0033] In this embodiment, the first lifting cylinder is also provided with an inverted U-shaped first mounting seat 11. The first mounting seat 11 spans the conveying groove 20 and the two material pulling holes 18 and is placed on the top plate. The interior of the first mounting seat 11 is provided with a cavity to accommodate the first lifting cylinder. The fixing block 15 is suspended above the conveying groove 20 by connecting the first lifting cylinder. The fixing block 15 moves up and down inside the first mounting seat 11.

[0034] In this embodiment, the lifting clamping assembly is further provided with two pressure blocks 13 and a connecting rod 14. The two pressure blocks 13 and the fixing block 15 are arranged along the conveying direction. The two pressure blocks 13 are located on both sides of the fixing block 15. The connecting rod 14 horizontally connects the fixing block 15 and the two pressure blocks 13. The two pressure blocks do not cover the material pulling through hole 18 to avoid affecting the material pulling stroke. The bending and tilting of the LED bracket will adversely affect the insertion of the tip of the insert 17 into the positioning hole. Therefore, the pressure blocks 13 located on both sides of the fixing block 15 are used to ensure the flatness of the LED bracket during material pulling, making the material pulling process more accurate and smooth. The connecting rod 14 is used to ensure the consistency and accuracy of the horizontal lifting of the three components.

[0035] The push-pull assembly includes a second drive motor 25, a lead screw 26, and a transmission seat 28. The second drive motor 25 is connected to the lead screw 26, and the lead screw 26 is connected to the transmission seat 28. The lead screw 26 and the transmission seat 28 are disposed within the mounting box 6. Sliding locking posts 27 are provided on both sides of the transmission seat 28, passing through the material pulling through hole 18. The fixing block 15 is provided with locking holes adapted to the sliding locking posts 27. After the fixing block 15 is engaged with the transmission seat 28, the second drive motor 25 pulls the transmission seat 28 and the fixing block 15 to perform the material pulling process.

[0036] The lifting stroke of the fixed block 15 is less than the height of the sliding pin 27. Its function is that after the fixed block 15 rises and releases the LED bracket, it still remains connected to the transmission seat 28, without needing to repeatedly align and engage with the transmission seat 28.

[0037] In this embodiment, the two pressing blocks 13 are raised and lowered by two second lifting cylinders. Each of the two second lifting cylinders is provided with an inverted U-shaped second mounting base 10. The interior of the second mounting base 10 is provided with a cavity to accommodate the second lifting cylinder. The pressing block 13 is suspended above the conveying trough 20 by connecting the second lifting cylinder, and the pressing block 13 rises and falls inside the second mounting base 10. The structure, connection method, and operation of the second lifting cylinder and the second mounting base 10 in this embodiment are the same as those of the first lifting cylinder and the first mounting base 11, which facilitates standardized and customized production.

[0038] The rapid pushing and pulling of the second drive motor 25 will inevitably cause vibration, which will affect the clamping of the LED bracket by the insert 17. Therefore, two slide rails 22 are symmetrically installed inside the mounting box 6 along the length direction. The two slide rails 22 are respectively set on the outside of the two material pulling holes 18. The transmission seat 28 is equipped with two sliders 23 that are adapted to the slide rails 22. The sliders 23 move along the slide rails 22. The main function of this structure is to stably guide the transmission seat 28, minimize vibration, and ensure that the material pulling is smooth and stable.

[0039] The mounting box 6 is equipped with a pull sensor 34 and a reset sensor 32. The pull sensor 34 is closer to the heating station than the reset sensor 32. The distance between the pull sensor 34 and the reset sensor 32 is equal to the length of the heating area of ​​the heating plate 24. The transmission base 28 is equipped with a sensing block 33 that is adapted to both the pull sensor 34 and the reset sensor 32.

[0040] When the pull sensor 34 detects the sensing block 33, it sends a signal to the control system. The control system then drives the first and second lifting cylinders to descend, the fixing block 15 clamps the LED bracket, and the second drive motor 25 pulls the transmission seat 28 to perform the material pulling process. The LED bracket that has been welded on the heating plate 24 is pulled away, and the heating plate 24 proceeds to weld the next area of ​​LED brackets. After the transmission seat 28 has moved past the heating area of ​​the heating plate 24, the sensing block 33 enters the detection range of the reset sensor 32. The reset sensor 32 sends a signal to the control system, which drives the first and second lifting cylinders to rise. The fixing block 15 releases the LED bracket, and the second drive motor 25 pushes the transmission seat 28 to reset, that is, the transmission seat 28 moves closer to the heating mechanism to reset, and performs the next material pulling, thus repeating the cycle. The reset time of the transmission seat 28 is equal to the heating time of the heating plate 24.

[0041] To improve the level of automation and intelligence in this embodiment, several sensors are installed on both sides of the vertical cabinet 1. Specifically:

[0042] The vertical cabinet 1 has a start sensor 9 and a stop heating sensor 8 on one side where the heating station is located. When the first end of the LED bracket enters the detection range of the start sensor 9, the start sensor 9 sends a signal to the control system, and the control system starts the heating mechanism and the material pulling mechanism; when the last end of the LED bracket enters the detection range of the stop heating sensor 8, the stop heating sensor 8 sends a signal to the control system, and the control system shuts down the heating plate 24.

[0043] The stop heating sensor 8 is closer to the material pulling station than the start sensor 9. Its functions are as follows: firstly, only when the distance between the start sensor 9 and the heating plate 24 is far enough will the heating plate 24 be fully preheated when the first end of the LED bracket reaches the heating station; secondly, only when the distance between the stop heating sensor 8 and the heating plate 24 is close enough will the residual heat of the heating plate 24 be sufficient to melt the solder paste when the tail end of the LED bracket reaches the heating station.

[0044] The vertical cabinet 1 has a start-up sensor 4 and a stop sensor 2 on one side of the material pulling station. When the first end of the LED bracket enters the detection range of the start-up sensor 4, the start-up sensor 4 sends a signal to the control system, and the control system starts the take-up tray 3 to begin winding up the LED bracket; when the last end of the LED bracket enters the detection range of the stop sensor 2, the stop sensor 2 sends a signal to the control system, and the control system stops the material pulling mechanism, the heating mechanism, and the material pulling mechanism.

[0045] The start-up take-up sensor 4 is installed flush with or below the lower end of the take-up tray 3 to ensure that the LED brackets that have completed the soldering process are long enough before winding, avoiding pulling and ensuring that the solder paste has sufficient cooling and curing time. The stop sensor 2 is located above the start-up take-up sensor 4, so that all mechanisms stop operating promptly after the tail end of the LED bracket has passed.

[0046] The vertical cabinet 1 is also equipped with a display screen 7 and control buttons. The display screen 7 is used to display the working status and real-time parameters of this embodiment, and the control buttons can be used to turn the machine on and off, set the temperature, and perform other operations.

[0047] The bottom of the vertical cabinet 1 is equipped with a platform frame to stabilize the overall center of gravity, and the platform frame is equipped with legs and casters.

[0048] The mounting box 6 has multiple heat dissipation holes on its side wall. Arc-shaped guides 5 are provided on both sides of the mounting box 6 to guide the LED bracket smoothly into the heating station along the inclined arc surface.

[0049] The sensors used in this embodiment are all photoelectric sensors.

[0050] In this embodiment, the LED bracket is connected to the die bonder on the production line. This means that when the LED bracket is delivered to this embodiment, the solder paste and LED chip on the LED bracket are already configured. Since most existing die bonders have their own feeding mechanism, a guide conveyor track (such as a common U-shaped / V-shaped guide trough) can be set between the die bonder and this embodiment.

[0051] The specific workflow of this embodiment is as follows:

[0052] 1. Start-up: The first end of the LED bracket enters the detection range of the start-up sensor 9. The start-up sensor 9 sends a signal to the control system, and the control system starts the heating mechanism and the material pulling mechanism (the heating mechanism and the material pulling mechanism have a short period of idling in this step, which does not affect the production of this embodiment in essence. Those skilled in the art can solve the idling problem by setting sensors in appropriate positions).

[0053] 2. Heating process: The first drive motor 30 controls the heating plate 24 to rise, and the heating plate 24 contacts the LED bracket to melt the solder paste. After the set heating time, the first drive motor 30 controls the heating plate 24 to fall, release the LED bracket, and the material pulling mechanism starts the material pulling process.

[0054] 4. Material pulling process: The first lifting cylinder and the second lifting cylinder descend simultaneously, the insert 17 of the fixing block 15 clamps the LED bracket, the second drive motor 25 pulls the transmission seat 28, and the LED bracket that has been welded is pulled out of the working area of ​​the heating plate 24, and the next part of the unheated LED bracket enters the working area of ​​the heating plate 24.

[0055] 5. Reset: When the transmission seat 28 enters the detection range of the reset sensor 32, the reset sensor 32 sends a signal to the control system. The control system controls the second drive motor 25 to push the transmission seat 28 to reset. The reset time of the transmission seat 28 is the same as the heating time of the heating plate 24. Therefore, when the transmission seat 28 enters the detection range of the pull sensing block 33 due to reset, the next material pulling process can be performed.

[0056] 6. Receiving: When the first end of the LED bracket enters the detection range of the start receiving sensor 4, the start receiving sensor 4 sends a signal to the control system, and the control system starts the receiving tray 3 to start winding the LED bracket.

[0057] 7. Closure: When the tail end of the LED bracket enters the detection range of the stop sensor 2, the stop sensor 2 sends a signal to the control system, and the control system stops the receiving mechanism, heating mechanism and pulling mechanism, thus completing the welding and receiving of one roll of LED bracket.

[0058] Compared with conventional soldering production lines equipped with reflow ovens, this embodiment integrates the material pulling mechanism and heating mechanism above the material receiving mechanism, resulting in a smaller equipment size and footprint, lower equipment cost, and direct connection to the die bonder. This allows for timely heating of the solder paste, preventing excessive volatilization of volatile components before soldering, optimizing the soldering effect, enabling continuous soldering, and effectively improving production efficiency.

[0059] The above embodiments do not limit the scope of protection of this invention. All equivalent modifications and variations made by those skilled in the art without departing from the overall concept of this invention are still within the scope of this invention.
