Description

Technical Field

[0001] The invention relates to the field of circuit board welding, and more specifically to a laser power supply circuit board processing welding device and a welding method thereof. Background Art

[0002] Soldering is the process of connecting various electronic components (such as resistors, capacitors, diodes, integrated circuits, etc.) on a circuit board together through wires or pins; these components need to be connected together accurately to ensure the normal operation of the circuit; welding can provide a reliable electrical connection so that current and signals can be transmitted between components;

[0003] Soldering not only provides electrical connections, but also firmly fixes components on the circuit board; this is essential to maintaining the stability and reliability of the circuit board; especially in vibration or shock environments, welding can provide stronger mechanical support to prevent components from falling off or loosening;

[0046] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making creative work are within the scope of protection of the present invention.

[0047] See also Figures 1 to 13, a laser power supply circuit board processing and welding equipment and a welding method thereof, comprising a seat plate 1, a surrounding shell 2 is fixedly installed at one end of the upper surface of the seat plate 1, a cover body 21 is fixedly installed around the top of the shell 2, a first motor 22 is fixedly installed on both sides of the cover body 21, a welding device 4 for welding is arranged around the shell 2, a first groove body 101 is opened at a position on the upper surface of the seat plate 1 corresponding to the welding device 4, a rotating component 3 for clamping the circuit board is rotatably installed inside the first groove body 101, a flip component 7 for changing the working state of the rotating component 3 is rotatably installed at a position of the seat plate 1 close to the rotating component 3, a storage box 9 is arranged below the seat plate 1, a loading component 8 is arranged on the side of the upper surface of the seat plate 1 away from the rotating component 3, and a discharging component 5 is arranged at a position corresponding to the rotating component 3 in the middle of the upper surface of the seat plate 1.

[0048] During actual use, by driving the first motor 22 to rotate forward, the welding device 4 can be driven to descend to weld the circuit board clamped on the rotating component 3. The welding device 4 is provided with a wire feeding pipe and a laser welding gun. When welding is completed, the first motor 22 is reversed. The reversal of the first motor 22 can drive the welding device 4 to rise. At this time, the rising of the welding device 4 will drive the flipping component 7 to work. The operation of the flipping component 7 will change the orientation of the circuit board on the rotating component 3, so that it can be turned over to achieve the effect of automatic reverse welding. At this time, the rotating component 3 does not rotate. When the welding device 4 descends again to complete the welding work and rises, it can drive the rotating component 3 to work and rotate. At this time, the rotation of the rotating component 3 will turn the welding device 4 The soldered circuit board below is rotated to the position of the unloading component 5, and during the rotation process, the circuit board clamped on the rotating component 3 can be automatically unloaded, thereby realizing automatic unloading of the soldered circuit board, so that the soldered circuit board will be automatically unloaded into the storage box 9 for storage. At the same time, the rotating component 3 will automatically load the unsoldered circuit board from the loading component 8 as it rotates. In this way, the reciprocating rotation of the first motor 22 can drive the rotating component 3 to automatically send the circuit board to the welding position, and can automatically unload the soldered circuit board, and can also automatically load the unsoldered circuit board, thereby reducing the tedious operation of manual loading by workers and improving production efficiency.

[0049] A first sliding block 41 is fixedly installed on both sides of the welding device 4, and the first sliding block 41 is slidably installed inside the shell 2. A screw rod 42 is fixedly installed on the middle part of the first sliding block 41 through a threaded fitting. The screw rod 42 is fixedly installed on the output end of the first motor 22. Replacement components 6 for changing the working state of the device are fixedly installed on the lower surfaces of both sides of the seat plate 1 close to the rotating component 3, and the two ends of the screw rod 42 are rotatably installed on the cover body 21 and the replacement component 6 respectively.

[0050] During operation, the first motor 22 drives the screw rod 42 to rotate forward and reverse. Because the first sliding block 41 and the screw rod 42 are threaded, when the screw rod 42 rotates forward, it can drive the first sliding block 41 to descend, and when the screw rod 42 reverses, it can drive the first sliding block 41 to rise. When the first sliding block 41 descends for the first time, it can drive the replacement component 6 to work and change to a flipping state. When the first sliding block 41 descends for the second time, it can drive the replacement component 6 to change to a material changing state. As the first sliding block 41 continues to rise and fall, the replacement component 6 can cyclically switch between the flipping state and the material changing state. When the replacement component 6 is in the flipping state, When the first motor 22 and the screw rod 42 are reversed, they can drive the flipping component 7 to turn over the circuit board on the rotating component 3 without driving the rotating component 3 to rotate. When the replacement component 6 is in the material replacement state, the first motor 22 and the screw rod 42 are reversed to drive the rotating component 3 to rotate for unloading and loading. The automatic flipping allows the device to weld both sides of the circuit board while the welding work is in progress, without the need for workers to manually flip it over, and after both sides of the circuit board are processed, the material can be automatically loaded and unloaded as the work progresses, which can further improve work efficiency without the need to stop the machine for replacement or loading and unloading operations.

[0051] The rotating component 3 includes a central block 31, four evenly distributed connecting rods 32 are fixedly installed on the outer circle of the central block 31, a U-shaped clamp 33 is rotatably installed on the end of the connecting rod 32, a reset plate 34 is fixedly installed on the connecting rod 32, a discharge trough 35 is provided on the connecting rod 32 and the U-shaped clamp 33, a slider 331 is integrally formed at one end of the U-shaped clamp 33 away from the connecting rod 32, and the central block 31 is rotatably installed inside the first trough body 101.

[0052] The circuit board sliding card is arranged inside the U-shaped card 33. Because the rotating part 3 is rotatably installed inside the first groove body 101, when the rotating part 3 rotates, the circuit board will be confined inside the U-shaped card 33 and will not fall out. The circuit board located below the welding device 4 can be welded by the welding device 4. When the flipping part 7 works, it can drive the U-shaped card 33 to rotate, thereby causing the circuit board thereon to rotate and turn over. As the rotating part 3 rotates as a whole, the welded circuit board can be rotated to the position of the unloading part 5. The unloading part 5 can slide the circuit board out of the U-shaped card 33 to achieve disassembly, so that the device can automatically unload when working, without the need for workers to manually unload after stopping the machine, thereby facilitating continuous production.

[0053] The replacement component 6 includes a U-shaped fixing frame 61, one end of the screw rod 42 is rotatably mounted on the U-shaped fixing frame 61, a fifth gear 62 is provided inside the U-shaped fixing frame 61, a first gear 11 is rotatably mounted on the lower surface of the seat plate 1 at a position corresponding to the rotating component 3, the first gear 11 is fixedly connected to the center block 31, second gears 12 are meshed on both sides of the first gear 11, the second gear 12 is rotatably mounted on the lower surface of the seat plate 1, the second gear 12 and the corresponding fifth gear 62 are transmitted by a chain, the fifth gear 62 is rotatably sleeved on the outer surface of the screw rod 42, the fifth gear 62 is rotatably mounted on the lower surface of the seat plate 1, a sixth gear 63 is provided below the fifth gear 62, the sixth gear 63 is slidably sleeved on the outer surface of the screw rod 42, a side surface of the fifth gear 62 close to the sixth gear 63 is integrally formed with a plurality of evenly distributed first ratchet teeth 621, and a side surface of the sixth gear 63 close to the fifth gear 62 is integrally formed with a plurality of second ratchet teeth 631 matching the first ratchet teeth 621. The external transmission of the sixth gear 63 includes a first rack transmission belt 64, and a plurality of evenly distributed matching teeth 641 are integrally formed on the lower surface of the first rack transmission belt 64. A support plate 65 is provided below the sixth gear 63, and the support plate 65 is movably sleeved on the outer surface of the screw rod 42. A second spring 651 is fixedly connected between the lower surface of the support plate 65 and the U-shaped fixing frame 61. First sliding plates 66 are fixedly installed at both ends of the lower surface of the support plate 65, and a Z-shaped rod 661 is rotatably installed on the first sliding plate 66. The U-shaped fixing frame 61 has two mechanism grooves for use with the first rack transmission belt 64. Second sliding plates 102 are slidably clamped at positions corresponding to the screw rod 42 on the seat plate 1, and the second sliding plates 102 are movably sleeved on the corresponding outer surfaces of the screw rod 42. The lower end of the second sliding plate 102 is fitted with the support plate 65, and the lower surface of the seat plate 1 is sleeved on the corresponding position of the flip component 7 and a fourth gear 15 is rotatably installed.

[0054] When the first sliding block 41 descends for the first time, the replacement component 6 is driven to turn over. At this time, the first sliding block 41 will push the second sliding plate 102 to descend, and the second sliding plate 102 will push the support plate 65 to descend. When the support plate 65 descends for the first time, it will drive the first sliding plate 66 and the Z-shaped rod 661 to descend. At this time, the Z-shaped rod 661 will be stuck in the mechanism groove, and the sixth gear 63 is rotatably installed on the upper surface of the support plate 65. Therefore, the descent of the support plate 65 will also drive the sixth gear 63 to descend. At this time, because the sixth gears 63 on the two replacement components 6 descend synchronously, the first The rack drive belt 64 is driven to descend synchronously. When the first rack drive belt 64 descends, it will drive the matching tooth 641 to engage with the fourth gear 15. Then, when the first rack drive belt 64 is driven by the sixth gear 63 to drive in reverse, it can drive the fourth gear 15 to rotate. When the fourth gear 15 rotates, it can drive the flipping component 7 to rotate. Then, the rotation of the flipping component 7 can drive the U-shaped clamp 33 and the circuit board thereon to rotate, thereby realizing the flipping effect, which is convenient for automatically flipping the circuit board as the work progresses, improving the integrity of welding, and improving welding efficiency.

[0055] When the first sliding block 41 descends for the second time, the replacement component 6 is driven to change the material replacement state. At this time, the first sliding block 41 pushes the second sliding plate 102 to move again. At this time, the second sliding plate 102 pushes the support plate 65 and the first sliding plate 66 and Z-shaped rod 661 thereon to descend. At this time, the lower surface of the seat plate 1 is sleeved on the corresponding position of the flip component 7 and the fourth gear 15 is rotated and installed. The mechanism groove releases the Z-shaped rod 661. Under the action of the second spring 651, the support plate 65 pushes the sixth gear 63 to rise and mesh with the first ratchet 621. The second ratchet 631 and the first ratchet 621 are set to prevent the sixth gear 63 from rotating forward and driving the fifth gear 62 to rotate forward, so that the fifth gear 62 can only be driven by the sixth gear 63 to reverse. When the fifth gear 62 is driven to reverse, the fifth gear 62 will drive the two second gears 12 to rotate through the chain. When the two When the second gear 12 rotates, it will drive the first gear 11 to rotate, and then the first gear 11 will drive the center block 31 to rotate. The number of teeth of the second gear 12 is smaller than that of the first gear 11, that is, the second gear 12 can only drive the first gear 11 to rotate a quarter of a circle each time it works, and then when the first sliding block 41 drops for the second time, it can drive the rotating component 3 to rotate, and then drive the circuit board thereon to be transmitted. When the first sliding block 41 drops again, the replacement component 6 turns to the flipping state again, so that the device can automatically switch back and forth between the flipping state and the material changing state when performing continuous work, and can automatically follow different welding pipe processes to flip the circuit board, unload the welded circuit board and load the unwelded circuit board at the same time, so as to realize continuous automatic work without stopping, and greatly increase the welding rate.

[0056] The mechanism groove is formed by the first channel 611, the second channel 612, the third channel 613, the fourth channel 614, and the fifth channel 615 which are connected and combined in sequence. There is a first peak 616 between the second channel 612 and the third channel 613, and there is a second peak 617 between the fourth channel 614 and the fifth channel 615. There is a step inside the fifth channel 615. The side of the step close to the first channel 611 is a vertical surface, and the side of the step close to the fourth channel 614 is an inclined surface.

[0057] When the first sliding plate 66 is driven by the support plate 65 to descend for the first time, the Z-shaped rod 661 is driven to descend and slide from the inside of the first channel 611 to the inside of the second channel 612. Because of the step, the first channel 611 will not enter the inside of the fifth channel 615, and the first channel 611 will slide along the second channel 612 to enter the inside of the third channel 613. At this time, when the first sliding block 41 rises, because of the second spring 651, the support plate 65 will drive the first sliding plate 66 and the Z-shaped rod 661 to rise. The first peak 616 is located on one side of the third channel 613 and is staggered. Therefore, the Z-shaped rod 661 will be blocked by the first peak 616 from entering the inside of the fourth channel 614. At this time, the Z-shaped rod 661 is blocked by the fourth channel The Z-shaped rod 661 is stuck in the fifth channel 614. When the Z-shaped rod 661 is driven to descend again, the Z-shaped rod 661 is blocked by the second peak 617 to enter the fifth channel 615. Because the step is close to the fourth channel 614 and is set as an inclined surface, the Z-shaped rod 661 can slide over the step. During this process, the Z-shaped rod 661 undergoes slight elastic deformation. When the Z-shaped rod 661 enters the fifth channel 615, under the action of the second spring 651, the Z-shaped rod 661 slides out of the fifth channel 615 and returns to the initial position, so that the welding device 4 can drive the replacement component 6 to change state when it is in different working states, so as to drive different work and realize automatic following of the working state of the welding device 4 for automatic control.

[0058] The flip component 7 includes a central axis 71, a rotating plate 72 is fixedly installed at one end of the central axis 71 close to the rotating component 3, a second arc groove 721 is opened in the middle of the side of the rotating plate 72 away from the central axis 71, a seventh gear 73 is provided on the side of the rotating plate 72 close to the central axis 71, the seventh gear 73 is rotatably sleeved on the outer surface of the central axis 71, a plurality of evenly distributed elastic sheets 711 are fixedly installed at the position of the central axis 71 close to the seventh gear 73, a plurality of ratchets used in conjunction with the elastic sheets 711 are integrally formed inside the seventh gear 73, and the fourth gear 15 is meshed with the seventh gear 73.

[0059] When the first rack transmission belt 64 descends, it will mesh with the fourth gear 15. At this time, the first rack transmission belt 64 drives the fourth gear 15 to rotate in the opposite direction, and the fourth gear 15 meshes with the seventh gear 73. Therefore, when the fourth gear 15 rotates in the opposite direction, the seventh gear 73 can be driven to rotate in the opposite direction. At this time, the ratchet teeth inside the seventh gear 73 are resisted by the elastic sheet 711, and then the seventh gear 73 can drive the central shaft 71 and the rotating plate 72 to rotate. When in use, the slider 331 is located inside the second arc groove 721, so when the second arc groove 721 rotates, it can drive the U-shaped clamping member 33 to rotate. The number of teeth of the seventh gear 73 is greater than that of the fourth gear 15. When the fourth gear 15 is driven to rotate forward, the seventh gear 73 will only be driven to rotate half a circle. When the fourth gear 15 is driven to rotate reversely, the friction between the central shaft 71 and the seat plate 1 causes the elastic sheet 711 to be elastically deformed, and then idle rotation occurs, preventing the flip component 7 from driving the U-shaped clamping member 33 to rotate in the opposite direction.

[0060] The unloading component 5 includes a unloading shell 51, a spring telescopic rod 52 is fixedly installed on the upper surface of the unloading shell 51, a second sliding block 53 is fixedly installed on the telescopic end of the spring telescopic rod 52, the second sliding block 53 is slidably installed on the upper surface of the unloading shell 51, a unloading rod 54 is fixedly installed on the lower surface of the second sliding block 53, the unloading rod 54 penetrates the unloading shell 51 and extends to the inside thereof, a unloading pipe 55 is fixedly installed on one side of the base plate 1, a fan 56 is fixedly installed on the unloading pipe 55, and one end of the unloading pipe 55 extends to the top of the storage box 9.

[0061] When the rotating part 3 rotates, the reset plate 34 is driven to rotate, which can produce a pushing effect on the unloading rod 54, and the unloading rod 54 will drive the second sliding block 53 to slide, and then the second sliding block 53 will squeeze the spring telescopic rod 52. When the rotating part 3 rotates a quarter of a turn, the unloading rod 54 enters the interior of the unloading chute 35, and the spring telescopic rod 52 is released to drive the second sliding block 53 and the unloading rod 54 to move. At this time, the unloading rod 54 can push the circuit board to slide out of the U-shaped clamp 33. Because the unloading pipe 55 is provided, the pushed out circuit board will slide along the unloading pipe 55 to the interior of the storage box 9, and the fan 56 can continuously deliver wind to the interior of the unloading pipe 55. On the one hand, it can cool the circuit board after welding, and on the other hand, it can produce a pushing effect on the circuit board to prevent it from clogging the unloading pipe 55, and at the same time improve the smoothness of unloading.

[0062] A loading trough 103 is provided at a position of the seat plate 1 near the loading component 8, and a loading block 104 is slidably clamped inside the loading trough 103, and a sliding rod 105 is fixedly installed on the side of the loading block 104 away from the rotating component 3, and the sliding rod 105 is slidably clamped inside the seat plate 1, and a first spring 106 is fixedly connected between the sliding rod 105 and the seat plate 1, and a first arc groove 107 is provided on the side of the loading block 104 away from the sliding rod 105, and a blocking plate 108 is fixedly installed on the upper surface of the loading block 104, and the blocking plate 108 is used to block the loading trough 103, and a blocking rod 109 is fixedly installed on the lower surface of the loading block 104, and the blocking rod 109 extends to the bottom of the seat plate 1, and a third gear 13 is rotatably installed on the lower surface of the seat plate 1, and the third gear 13 is located between the first gear 11 and the loading component 8, and the third gear 13 is connected to the first gear 11 through a chain. Four evenly distributed arc plates 14 are fixedly installed on the upper surface, and the feeding component 8 includes a storage box 81. Two symmetrical pairs of support frames 82 are fixedly installed on the lower surface of the storage box 81. Two symmetrical welding devices 4 are rotatably installed on the support frame 82. A transmission belt 85 is transmitted between two corresponding transmission rollers 84. A plurality of evenly distributed rubber blocks 851 are integrally formed on the transmission belt 85. A second groove body 841 is provided inside the upper transmission roller 84. A second motor 86 is fixedly installed on one side of the support frame 82. A driving shaft 861 is fixedly installed on the driving end of the second motor 86. The driving shaft 861 has a plurality of evenly distributed protrusions 862. The second groove body 841 is inserted into the internal sliding card and is provided with a matching block 842. The matching block 842 is provided with a plurality of circular grooves corresponding to the protrusions 862, and a third spring 843 is fixedly connected between the matching block 842 and the second groove body 841.

[0063] Before use, workers first stack the circuit boards neatly inside the storage box 81. When the device starts working, the second motor 86 drives the transmission roller 84 to rotate. When the transmission roller 84 rotates, it can drive the transmission belt 85 to transmit. The rubber block 851 on the two transmission belts 85 can clamp the circuit boards dropped from the storage box 81 and separate each circuit board. With the transmission of the transmission belt 85, the unsoldered circuit boards will be transported to the upper surface of the blocking plate 108. At this time, because the circuit boards are supported by the blocking plate 108, the circuit boards between the two transmission belts 85 cannot be transported. At this time, the protrusion 862 on the drive shaft 861 will lose the connection with the matching block 842, causing the drive shaft 861 to slip. The second motor 86 cannot drive the transmission roller 84 to rotate, thereby realizing intermittent loading. It can also follow the rotating component 3 for automatic loading. Only when the circuit board on the rotating component 3 is removed to create a vacancy will it be automatically loaded to prevent material accumulation and protect the integrity of the unsoldered circuit boards.

[0064] When the rotating component 3 rotates, the first gear 11 will drive the third gear 13 to rotate synchronously. At this time, the third gear 13 will drive the arc plate 14 to rotate. When the arc plate 14 rotates, it can push the blocking rod 109. At this time, the blocking rod 109 drives the loading block 104 and the blocking plate 108 to move until the loading block 104 moves to one side of the loading trough 103. At this time, the circuit board above the slide bar 105 will be conveyed into the interior of the loading trough 103. When the rotating component 3 stops rotating, at this time, the slide bar 105 will push the loading block 104 and the blocking plate 108 to move under the action of the first spring 106. When the loading block 104 moves, it can push the circuit board to move into the interior of the U-shaped clamp 33. The first arc groove 107 is used to prevent the blocking slider 331 from rotating, so that the slider 331 can rotate stably with the rotating component 3, making it more stable when loading, and after the loading is completed, the circuit board can follow the rotation of the rotating component 3 and better separate from the loading block 104.

[0065] A laser power supply circuit board welding method,

[0066] S1: When in use, first control the first motor 22 to drive the screw rod 42 to rotate forward. When the screw rod 42 rotates forward, it can drive the welding device 4 to descend. At this time, the welding device 4 can weld the circuit board clamped on the rotating component 3. The welding device 4 has a laser welding gun and a wire feeding component, and then welds the circuit board;

[0067] S2: When welding is completed, the first motor 22 controls the screw rod 42 to reverse, thereby causing the first sliding block 41 to rise;

[0068] S3: When the welding device 4 descends, the Z-shaped rod 661 is stuck in the mechanism groove. At this time, the screw rod 42 reverses to drive the sixth gear 63 and the first rack transmission belt 64 to transmit. When the first rack transmission belt 64 transmits, it can drive the flipping component 7 to work and change the state of the U-shaped clamp 33 to flip the U-shaped clamp 33;

[0069] S4: When the flipping is completed, the first motor 22 controls the screw rod 42 to rotate forward again. At this time, idling occurs between the seventh gear 73 and the central axis 71, making it impossible to be driven to flip. At this time, the welding device 4 descends to weld the back side of the circuit board. When the welding device 4 descends, it can press the first sliding plate 66 again through the second sliding plate 102. At this time, the mechanism groove releases the Z-shaped rod 661.

[0070] S5: When the welding of the back side of the circuit board of the welding device 4 is completed, the first motor 22 is controlled to reverse again to drive the welding device 4 to rise. At this time, the sixth gear 63 is pushed up by the second spring 651. At this time, the second ratchet 631 is engaged with the first ratchet 621. The rotation of the sixth gear 63 drives the fifth gear 62 to rotate. When the fifth gear 62 rotates, it can drive the rotating component 3 to rotate, and then drive the circuit board to transmit.

[0071] S6: When the rotating component 3 rotates, it can drive the circuit board to move from the working position below the welding device 4 to the unloading position of the unloading component 5. At this time, the circuit board inside the U-shaped clamp 33 is automatically unloaded through the unloading pipe 55 into the interior of the storage box 9;

[0072] S7: At the same time, the empty U-shaped fixture 33 is rotated from the unloading position to the loading position on one side of the loading component 8. At this time, the loading block 104 can push the unsoldered circuit board into the interior of the U-shaped fixture 33 under the push of the first spring 106;

[0073] S8: When the rotating component 3 rotates, the third gear 13 can be driven to rotate through the first gear 11, and then the arc plate 14 on the third gear 13 can drive the blocking rod 109 to reset. During the resetting process, the circuit board inside the loading component 8 will be transported to the loading block 104 by the second motor 86 for loading.

[0074] Working principle: during operation, the first motor 22 drives the screw rod 42 to rotate forward and drive the first sliding block 41 to descend, and when the screw rod 42 is reversed, it can drive the first sliding block 41 to rise. When the first sliding block 41 descends for the first time, it can drive the replacement component 6 to work and change to a flipping state. When the first sliding block 41 descends for the second time, it can drive the replacement component 6 to change to a material changing state. As the first sliding block 41 continues to rise and fall, the replacement component 6 can cyclically switch between the flipping state and the material changing state. When the replacement component 6 is in the flipping state, the first motor 22 and the screw rod 42 are reversed, which can drive the flipping component 7 to work and turn over the circuit board on the rotating component 3 without driving the rotating component 3 to rotate; when the replacement component 6 is in the material changing state, the first motor 22 and the screw rod 42 are reversed, which can drive the rotating component 3 to rotate. When the rotating component 3 is driven to rotate, the unloading component 5 can automatically unload the soldered circuit board, and the loading component 8 can simultaneously load the empty U-shaped card 33.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and its improved conception within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
