Description

Technical Field

[0001] The present invention relates to the technical field of chip welding processing, and in particular to a reflow soldering fixture for intelligent robot chip processing. Background Art

[0002] Reflow soldering refers to the process of connecting one or more electronic components to contact pads using solder paste (a mixture of solder and flux), and then melting the solder by controlled heating to achieve a permanent joint. Soldering can be performed using different heating methods such as reflow ovens, infrared heating lamps or hot air guns. Reflow soldering is the most commonly used method for bonding electronic components to printed circuit boards using surface mount technology (SMT). Through-hole assembly is to fill the existing holes on the circuit board with solder paste, insert the pins into the solder paste and embed the electronic components into the board for soldering. Since wave soldering is cheaper and simpler, reflow soldering is basically not used on through-hole circuit boards. When used on circuit boards containing both SMT and THT components, through-hole reflow soldering can replace wave soldering and effectively reduce assembly costs.

[0003] After searching, the patent with announcement number 202211432578.5 discloses "a reflow soldering fixture for chip processing", including a welding plate, a support rod is fixedly connected to the top of the welding plate, a sliding rod is arranged above the welding plate, and a reflow soldering device is arranged above the welding plate.

[0004] However, when the above-mentioned clamp is in use, since the positioning plates and recessed hole plates on both sides move toward the middle synchronously, it can often only clamp square chips. When encountering a rectangular chip, it will only clamp the two ends of the rectangular chip. The clamping is not firm enough, and when the placement position of the rectangular chip is not accurate enough, the rectangular chip cannot be automatically adjusted, causing inconvenience in use.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. In the present invention, the starting motor drives the screw to rotate, and the screw drives the connecting plates 1 on both sides to move in a direction approaching each other on the clamping table. The connecting plate 1 will also drive the spring 1, guide rod 1 and main clamping plate on both sides to move synchronously. The main clamping plate will also drive the fixed plate, guide rod 3 and magnetic plate to move synchronously. When the magnetic plate moves to the lower side of the magnetic block plate, it will move downward under the action of magnetic repulsion, and then the magnetic plate will also drive the guide rod 3 and the lifting plate to descend synchronously, compress the spring 3, and the lifting plate will also drive the rotating shaft and the cleaning strip to descend synchronously. The cleaning strip is convenient for scraping off the welding slag adhered to the surface of the movable clamping piece, so as to prevent the welding slag from adhering to the movable clamping piece and affecting the subsequent chip clamping stability, thereby ensuring the subsequent welding quality of the chip.

[0021] 2. In the present invention, when the cleaning bar descends, the push rod will also be driven to descend, and the push rod will be blocked by the inclined block on the inclined block plate, which will cause the push rod and the cleaning bar to tilt and rotate on the rotating shaft, compressing the torsion spring. When the push rod is separated from the inclined block on the inclined block plate, the cleaning bar will be driven to reset under the action of the torsion spring, so that the cleaning bar will swing back and forth while descending, which is conducive to scraping off the welding slag that is relatively firmly adhered, ensuring the cleaning quality of the movable clamp and the welding quality of the subsequent chips.

[0022] 3. In the present invention, when the magnetic plate descends, it will cooperate with the main clamping plate to squeeze the airbag, so that the gas in the airbag is discharged from the air outlet groove, which is convenient for blowing the welding slag scattered on the clamping table into the through groove, ensuring the cleanliness of the clamping table and playing an auxiliary role in the subsequent chip clamping stability.

[0023] 4. In the present invention, when the magnetic plates on both sides pass over the magnetic block plates, the magnetic plates, guide rod three and lifting plates will be pushed to reset under the action of spring three, and the lifting plates will also drive the rotating shaft, cleaning strip and top rod to rise and reset, and the motor will stop working. At this time, the main clamping plates on both sides will also stop moving, and the rectangular chip will be placed on the middle of the clamping table, so that the width of the two ends of the rectangular chip corresponds to the main clamping plates on both sides, and the length of the two ends of the rectangular chip corresponds to the auxiliary clamping plates on both sides. The motor is started again to drive the main clamping plates on both sides to move toward the width of the two ends of the rectangular chip, and the set active clamping pieces will first contact with the width of the two ends of the rectangular chip and clamp the rectangular chip to fix it. As the connecting plates 1 on both sides continue to move closer to each other, the connecting plate 1 on the left side will also drive the inclined plates on both sides to approach the direction of the L-shaped plates on both sides, and the inclined plates on both sides respectively squeeze the L-shaped plates on both sides, forcing the L-shaped plates on both sides to drive The auxiliary clamps on both sides slide in the direction of approaching each other, compressing spring four to clamp the two end lengths of the rectangular chip, and the auxiliary clamps on both sides move synchronously, which can push the two end lengths of the rectangular chip. The rectangular chip will drive the active clamps clamped on both sides to slide back and forth adaptively on the main clamp and guide rod two, compressing or stretching spring two until the auxiliary clamps on both sides are respectively in contact with the long ends of the chip, so as to facilitate automatic correction of the position of the rectangular chip to prevent the rectangular chip from being insufficient and ensure the quality of subsequent welding. The set active clamps can slide adaptively on the main clamp, avoiding the main clamp directly clamping and fixing the chip. When the auxiliary clamp pushes the rectangular chip for automatic correction, the two ends of the rectangular chip that have been squeezed and fixed by the main clamp will have excessive friction with the surface of the main clamp when adjusting their position, thereby ensuring that the rectangular chip will not be damaged by friction.

[0024] 5. In the present invention, when the movable clip adaptively moves forward and backward, it will also drive the connecting plate 2 and the roller to move synchronously. The roller is arranged to roll in the card slot plate, which is convenient for reducing the friction force when the movable clip and the connecting plate 2 slide, making the movable clip and the connecting plate 2 slide more smoothly, thereby playing a good auxiliary effect on the adaptive sliding adjustment of the rectangular chip.

A secondary splint 25 is symmetrically slidably installed on the front and rear sides of the upper end of the clamping platform 1, and an L-shaped plate 26 is fixedly installed on the end of the secondary splint 25 away from each other. The lower end of the L-shaped plate 26 is slidably installed on the clamping platform 1, and a vertical plate 27 is fixedly installed on the upper end of the clamping platform 1 between the secondary splint 25 and the L-shaped plate 26, and a spring four 28 is fixedly installed between the vertical plate 27 and the L-shaped plate 26.

The cleaning strip 14 is arranged to facilitate the scraping of the welding slag adhered to the surface of the movable clamping piece 8 to prevent the welding slag from adhering to the movable clamping piece 8 and affecting the subsequent chip clamping stability, thereby ensuring the subsequent welding quality of the chip. When the strip 14 descends, it will also drive the push rod 141 to descend. The push rod 141 will be blocked by the inclined block on the inclined block plate 142, which will cause the push rod 141 and the cleaning strip 14 to tilt and rotate on the rotating shaft 15, compressing the torsion spring 17. When the push rod 141 is separated from the inclined block on the inclined block plate 142, the cleaning strip 14 will be driven to reset under the action of the torsion spring 17, so that the cleaning strip 14 will be lowered and will also swing back and forth, which is conducive to scraping off the welding slag that adheres more firmly, ensuring the cleaning quality of the movable clamping piece 8 and the welding quality of the subsequent chips. When the magnetic plate 21 descends, it will also cooperate with the main clamping plate 2 to squeeze the air bag 23, so that the gas in the air bag 23 is discharged from the air outlet groove 24, which is convenient for blowing the welding slag scattered on the clamping table 1 into the through groove 30, ensuring the cleanliness of the clamping table 1 and playing an auxiliary role in the subsequent chip clamping stability.

[0039] As an embodiment of the present invention, a cleaning mechanism for cleaning welding slag on the clamping table 1 and the movable clamping piece 8 is also provided, and the cleaning mechanism includes a cleaning strip 14 that is abutted and fitted on the end of the movable clamping piece 8 that is close to each other, and a push rod 141 is fixedly installed on the rear side of the upper end of the cleaning strip 14, and an inclined block plate 142 is fixedly installed on the push rod 141 at the end of the main clamping plate 2 that is close to each other, and a rotating shaft 15 is rotatably installed through the middle part of the cleaning strip 14, and a lifting plate 16 is fixedly installed on the end of the rotating shaft 15 that is away from each other, and a torsion spring 17 is sleeved on the outer side of the rotating shaft 15, and guide rods 14 are fixedly installed on both the front and rear sides of the upper end of the lifting plate 16 18, a fixed plate 19 is slidably installed on the upper side of the guide rod 3 18, one end of the fixed plate 19 is fixedly installed on the main splint 2, a magnetic plate 21 is fixedly installed on the upper end of the guide rod 3 18, a spring 3 20 is sleeved on the outer side of the guide rod 3 18, and a magnetic block plate 22 is fixedly installed on the magnetic plates 21 on both sides corresponding to the upper rear side of the clamping table 1, the magnetic block plate 22 is located between the magnetic plates 21 on both sides, an air bag 23 is fixedly installed between the main splint 2 and the magnetic plate 21, an air outlet groove 24 is opened on the lower side of the end of the main splint 2 close to each other, the air outlet groove 24 is communicated with the inside of the air bag 23, and a plurality of through grooves 30 are opened on the clamping table 1 corresponding to the air outlet groove 24;

[0040] During operation, when the magnetic plates 21 on both sides pass over the magnetic block plates 22, the magnetic plates 21, the guide rods 18 and the lifting plates 16 will be pushed to reset under the action of the springs 20, and the lifting plates 16 will also drive the rotating shaft 15, the cleaning strip 14 and the top rod 141 to rise and reset, and the motor 7 will stop working. At this time, the main clamping plates 2 on both sides will also stop moving, and the rectangular chip will be placed on the middle part of the clamping table 1, so that the widths of the two ends of the rectangular chip correspond to the main clamping plates 2 on both sides, and the lengths of the two ends of the rectangular chip correspond to the auxiliary clamping plates 25 on both sides, and the motor 7 will be started again to drive the main clamping plates 2 on both sides to the two ends of the rectangular chip. The side width movement, the movable clamping piece 8 will first contact the two end widths of the rectangular chip and clamp the rectangular chip. As the connecting plates 14 on both sides continue to move closer to each other, the connecting plate 14 on the left side will also drive the inclined panels 29 on both sides to approach the L-shaped plates 26 on both sides. The inclined panels 29 on both sides respectively squeeze the L-shaped plates 26 on both sides, forcing the L-shaped plates 26 on both sides to drive the auxiliary clamping plates 25 on both sides to slide in the direction of approaching each other, compressing the spring 28, clamping the two end lengths of the rectangular chip, and the auxiliary clamping plates 25 on both sides are synchronous. The rectangular chip can be pushed by the two ends of the rectangular chip, and the rectangular chip will drive the movable clamping pieces 8 clamped on both sides to slide back and forth adaptively on the main clamping plate 2 and the guide rod 12, compressing or stretching the spring 13, until the auxiliary clamping plates 25 on both sides are respectively in contact with the long ends of the chip, so as to facilitate the automatic correction of the position of the rectangular chip, prevent the rectangular chip from being insufficient, and ensure the quality of subsequent welding. The movable clamping piece 8 can slide adaptively on the main clamping plate 2, avoiding the auxiliary clamping plate 25 pushing the rectangular chip to move after the main clamping plate 2 is directly clamped and fixed with the chip. During automatic correction, the two ends of the rectangular chip that have been squeezed and fixed by the main clamping plate 2 will have excessive friction with the surface of the main clamping plate 2 when adjusting their position, ensuring that the rectangular chip will not be damaged by friction. When the movable clamping piece 8 adaptively moves back and forth, it will also drive the connecting plate 2 9 and the roller 10 to move synchronously. The set roller 10 rolls in the slot plate 11, which is convenient for reducing the friction force when the movable clamping piece 8 and the connecting plate 2 9 slide, making the movable clamping piece 8 and the connecting plate 2 9 slide more smoothly, thereby playing a good auxiliary effect on the adaptive sliding adjustment of the rectangular chip.

[0041] Working principle:

[0042] When the present invention is used, the starting motor 7 drives the screw rod 6 to rotate, and the screw rod 6 drives the connecting plates 4 on both sides to move in a direction close to each other on the clamping table 1, and the connecting plates 4 will also drive the springs 5, the guide rods 3 and the main clamping plate 2 on both sides to move synchronously, and the main clamping plate 2 will also drive the fixed plate 19, the guide rods 3 18 and the magnetic plate 21 to move synchronously. When the magnetic plate 21 moves to the lower side of the magnetic block plate 22, it will move downward under the action of magnetic repulsion, and then the magnetic plate 21 will also drive the guide rods 3 18 and the lifting plate 16 to descend synchronously, compress the springs 3 20, and the lifting plate 16 will also drive the rotating shaft 15 and the cleaning strip 14 to descend synchronously. The cleaning strip 14 is provided to facilitate scraping off the welding slag adhered to the surface of the movable clamping piece 8 to prevent the welding slag from adhering to the movable clamping piece 8, which has an effect When the cleaning bar 14 is lowered, the ejector rod 141 will be driven down, and the ejector rod 141 will be blocked by the inclined block on the inclined plate 142, and the ejector rod 141 and the cleaning bar 14 will be tilted and rotated on the rotating shaft 15, compressing the torsion spring 17. When the ejector rod 141 is separated from the inclined block on the inclined plate 142, the cleaning bar 14 will be driven to reset under the action of the torsion spring 17, so that the cleaning bar 14 will be lowered and reciprocated, which is conducive to scraping off the welding slag that is relatively firmly adhered, ensuring the cleaning quality of the movable clamping piece 8 and the welding quality of the subsequent chips. When the magnetic plate 21 is lowered, it will also cooperate with the main clamping plate 2 to squeeze the air bag 23, so that the gas in the air bag 23 is released from the main clamping plate 2 The air outlet groove 24 is discharged, which is convenient for blowing the scattered welding slag on the clamping table 1 into the through groove 30, ensuring the cleanliness of the clamping table 1 and playing an auxiliary role in the subsequent chip clamping stability. When the magnetic plates 21 on both sides pass over the magnetic block plate 22, the magnetic plates 21, the guide rods 3 18 and the lifting plate 16 will be pushed to reset under the action of the spring three 20. The lifting plate 16 will also drive the rotating shaft 15, the cleaning strip 14 and the top rod 141 to rise and reset. The motor 7 stops working. At this time, the main clamping plates 2 on both sides will also stop moving, and the rectangular chip will be placed on the middle part of the clamping table 1, so that the width of the two ends of the rectangular chip corresponds to the main clamping plates 2 on both sides, and the length of the two ends of the rectangular chip corresponds to the auxiliary clamping plates 25 on both sides. The motor 7 is started again to drive the main clamping plates 2 on both sides to move toward the width of the two sides of the rectangular chip. The movable clamping piece 8 will first contact the wide ends of the rectangular chip and clamp the rectangular chip. As the connecting plates 14 on both sides continue to move closer to each other, the connecting plate 14 on the left side will also drive the inclined plates 29 on both sides to move closer to the L-shaped plates 26 on both sides. The inclined plates 29 on both sides respectively squeeze the L-shaped plates 26 on both sides, forcing the L-shaped plates 26 on both sides to drive the auxiliary clamping plates 25 on both sides to slide in the direction of approaching each other, compressing the spring 4 28 to clamp the two ends of the rectangular chip, and the auxiliary clamping plates 25 on both sides move synchronously, which can push the two ends of the rectangular chip. The rectangular chip will drive the clamped movable clamping pieces 8 on both sides to slide back and forth on the main clamping plate 2 and the guide rod 2 12 adaptively, compressing or stretching the spring 2 13,Until the auxiliary clamps 25 on both sides are in contact with the long ends of the chip respectively, it is convenient to automatically correct the position of the rectangular chip, prevent the rectangular chip from being insufficient, and ensure the quality of subsequent welding. The movable clamp 8 can slide adaptively on the main clamp 2, avoiding that after the main clamp 2 is directly clamped and fixed with the chip, when the auxiliary clamp 25 pushes the rectangular chip for automatic correction, the two ends of the rectangular chip that have been squeezed and fixed by the main clamp 2 will have excessive friction with the surface of the main clamp 2 when adjusting their positions, ensuring that the rectangular chip will not be damaged by friction. When the movable clamp 8 moves back and forth adaptively, it will also drive the connecting plate 2 9 and the roller 10 to move synchronously. The roller 10 rolls in the slot plate 11, which is convenient to reduce the friction between the movable clamp 8 and the connecting plate 2 9 when they slide, so that the movable clamp 8 and the connecting plate 2 9 can slide more smoothly, thereby playing a good auxiliary effect on the adaptive sliding adjustment of the rectangular chip.

A fixed plate (19) is installed through the sliding, one end of the fixed plate (19) is fixedly installed on the main clamping plate (2), a magnetic plate (21) is fixedly installed on the upper end of the guide rod three (18), a spring three (20) is sleeved on the outer side of the guide rod three (18), and a magnetic block plate (22) is fixedly installed on the rear side of the upper end of the clamping platform (1) corresponding to the magnetic plates (21) on both sides, the magnetic block plate (22) is located between the magnetic plates (21) on both sides, an air bag (23) is fixedly installed between the main clamping plate (2) and the magnetic plate (21), an air outlet groove (24) is opened on the lower side of the end of the main clamping plate (2) close to each other, the air outlet groove (24) is communicated with the inside of the air bag (23), and a plurality of through grooves (30) are opened on the clamping platform (1) corresponding to the air outlet groove (24); The method for using the reflow soldering fixture for intelligent robot chip processing is as follows: the motor (7) is started to drive the screw rod (6) to rotate, the screw rod (6) drives the connecting plates (4) on both sides to move in a direction close to each other on the clamping table (1), the connecting plates (4) also drive the springs (5) on both sides, the guide rods (3) and the main clamping plate (2) to move synchronously, the main clamping plate (2) also drives the fixed plate (19), the guide rods (18) and the magnetic plate (21) to move synchronously, when the magnetic plate (21) moves to the lower side of the magnetic block plate (22), it will move downward under the action of magnetic repulsion, and then the magnetic plate (21) will also drive the guide rods (18) and the lifting plate (16) to descend synchronously, compress the springs (20), and the lifting plate (16) will also drive the rotating shaft ( 15) and the cleaning bar (14) are synchronously lowered. When the cleaning bar (14) is lowered, the push rod (141) is also driven to lower. The push rod (141) is blocked by the inclined block on the inclined block plate (142), so that the push rod (141) and the cleaning bar (14) are tilted and rotated on the rotating shaft (15), compressing the torsion spring (17). When the push rod (141) is separated from the inclined block on the inclined block plate (142), the cleaning bar (14) is driven to reset under the action of the torsion spring (17), so that the cleaning bar (14) is lowered and reciprocated. When the magnetic plate (21) is lowered, it will cooperate with the main splint (2) to squeeze the air bag (23), so that the gas in the air bag (23) is discharged from the air outlet groove (24). When the magnetic plates (21) on both sides are lowered, the air bag (23) is pressed. When the chip passes over the magnetic plate (22), the magnetic plate (21), the guide rod (18) and the lifting plate (16) are pushed back to their original positions under the action of the spring (20). The lifting plate (16) also drives the rotating shaft (15), the cleaning strip (14) and the top rod (141) to rise and return to their original positions. The motor (7) stops working. At this time, the main clamping plates (2) on both sides also stop moving. The rectangular chip is placed on the middle part of the clamping table (1) so that the width of the two ends of the rectangular chip corresponds to the main clamping plates (2) on both sides, and the length of the two ends of the rectangular chip corresponds to the auxiliary clamping plates (25) on both sides. The motor (7) is started again to drive the main clamping plates (2) on both sides to move toward the width of the two sides of the rectangular chip. The movable clamping pieces (8) are first in contact with the width of the two ends of the rectangular chip and clamp the rectangular chip. The two connecting plates (4) on both sides continue to move towards each other, and the connecting plate (4) on the left side will also drive the inclined plates (29) on both sides to move towards the L-shaped plates (26) on both sides. The inclined plates (29) on both sides respectively squeeze the L-shaped plates (26) on both sides, forcing the L-shaped plates (26) on both sides to drive the auxiliary clamping plates (25) on both sides to slide in the direction of approaching each other, compressing the spring four (28) to clamp the two ends of the rectangular chip, and the auxiliary clamping plates (25) on both sides move synchronously to push the two ends of the rectangular chip. The rectangular chip will drive the movable clamping pieces (8) clamped on both sides to slide back and forth on the main clamping plate (2) and the guide rod two (12) adaptively, compressing or stretching the spring two (13).Until the auxiliary clamping plates (25) on both sides are in contact with the long ends of the chip, the movable clamping plate (8) can slide adaptively on the main clamping plate (2). When the movable clamping plate (8) moves adaptively forward and backward, it will also drive the second connecting plate (9) and the roller (10) to move synchronously, and the roller (10) can roll in the card slot plate (11).
