Description

Technical Field

[0001] The present application relates to the technical field of connector welding, and in particular to an electronic connector welding processing device. Background Art

[0002] Electronic connectors are also called circuit connectors or electrical connectors. They usually refer to conductor devices that bridge two conductors on a loop so that current or signals can flow from one conductor to another. In most usage scenarios, electronic connectors are generally installed on the motherboard by welding. Connectors fixed by welding can be better fixed on the circuit board and have high mechanical strength. They can withstand a certain degree of vibration and impact, and are also immune to environmental factors such as moisture, oxidation, acid and alkali corrosion. When welding multiple electronic connectors at one time, a welding method called wave soldering is usually used. Wave soldering is a method of spraying molten soft solder (such as lead-tin alloy, tin-silver-copper alloy, etc.) into a solder wave crest as required by the design through a power device such as an electric pump or an electromagnetic pump. However, the existing wave soldering pool cannot change the spray size during use, and cannot be flexibly changed for electronic connectors of different sizes. When the number of pins on the electronic connector is small and the solder liquid is laid over an excessive area, it is very easy to cause problems such as continuous welding or welding burrs, and then cause short circuits or circuit disconnection.

The other sides of the two groups of connecting pieces 83 are movably hinged with third hydraulic rods 84. The telescopic ends of the two groups of third hydraulic rods 84 are fixedly connected with second electric rotating shafts 85. By adjusting the stroke of the third hydraulic rod 84 and the rotation of the second electric shaft 85, the length of the curled steel sheet 82 extending to both sides can be changed. When the stroke of the third hydraulic rod 84 increases, the curled steel sheet 82 in the first electric shaft 81 will be pulled through the connecting piece 83 to extend it outward, thereby expanding the liquid area of ​​​​the molten tin. When the third hydraulic rod 84 shortens its stroke, the curled steel sheet 82 will be rewound around the outer edge of the first electric shaft 81, thereby reducing the welding area, solving the problem that the traditional wave soldering pool cannot flexibly change the welding area, resulting in continuous welding or welding burrs. The strip nozzle 75 is shaped like an inverted trapezoidal strip liquid outlet. The molten tin liquid will be uniformly sprayed upward through the strip nozzle 75.

According to different placement angles and positions, the electric gripper 26 can be driven to rotate by the rotation of the ring motor 24, and the insertion can be completed under the movement of the first track 21 and the movable block 23; The transport component 3 includes a plurality of columns 31, which are fixedly mounted on the top of the bottom plate 1, and a second track 32 is fixedly connected to the inner side of the plurality of columns 31.

A plurality of openings 36 of different shapes are opened in the vertical direction of the tray 35. A circuit board 37 is placed inside the tray 35, and a plurality of connectors 38 are plugged into the top of the circuit board 37. The circuit board 37 to which the connector 38 needs to be welded can be placed in the tray 35, and the electric wheel 34 can be moved clockwise to enable the tray 35 to move to the right along the second track 32. The tray 35 and the connector 38 can be replaced according to different production needs; The spraying assembly 4 includes a screw rod 41, which is fixedly mounted on the bottom of the tray 35.

A feed pipe is fixedly connected to the left end of the circular spray head 45. The liquid storage tank 46 is connected to the circular spray head 45 through the feed pipe. The stepper motor 42 moves left and right on the screw rod 41, and under the rotation and extension of the mechanical arm 43, the circular nozzle 45 with the closed component 5 is moved to the position of the pins exposed by the opening 36 to spray the soldering flux. During the process of spraying the soldering flux, only the pins of the connector 38 exposed at the opening 36 can be in contact with the molten tin liquid for soldering, and the rest of the circuit board 37 will not be tinned; The sealing component 5 includes a circular ring 51, which is fixedly mounted on the top of the circular nozzle 45. The circular ring 51 has a plurality of rectangular blocks 52 in a circular array. The outer sides of the plurality of rectangular blocks 52 are sleeved with an annular spring 53. The inner sides of the plurality of rectangular blocks 52 are movably hinged with a plurality of sealing plates 54. When the circular nozzle 45 sprays upward, the multiple sealing plates 54 will be stressed and drive the multiple rectangular blocks 52 to move outward. At this time, the gaps between the multiple sealing plates 54 will become larger, allowing the flux to pass through. When the circular nozzle 45 stops spraying, the sealing plates 54 are no longer stressed. At this time, the annular spring 53 that was previously squeezed and deformed recovers its elastic potential energy and squeezes the multiple rectangular blocks 52 toward the middle of the circular ring 51 again. The multiple sealing plates 54 merge to complete the blocking. First, the spraying can be stopped quickly, and second, the problem of the flux that has been sprayed flowing back can be reduced.

The two second hydraulic rods 61 increase the stroke and drive the fixing box 62 upward, thereby allowing the two preheated first heating wires 63 and second heating wires 64 to be as close as possible to the pins sprayed with soldering flux, so that the active ingredients in the soldering flux can fully function; The circulation component 7 includes two vertical plates 71, both of which are fixedly installed at the bottom of the second track 32. A heating tank 72 is fixedly installed in the two vertical plates 71. The left and right sides of the heating tank 72 are fixedly connected with connecting pipes 74. The other ends of the two connecting pipes 74 are fixedly installed with recovery tanks 73. A strip nozzle 75 is fixedly installed on the top of the heating tank 72. The left and right sides of the strip nozzle 75 are fixedly connected with spacers 76. The bottoms of the two vertical plates 71 are fixedly connected to the bottom plate 1. The inner walls of the two vertical plates 71 are fixedly connected to the first electric rotating shaft 81 and the two ends of the second electric rotating shaft 85. The outer sides of the two spacers 76 are in contact with the curled steel sheet 82. At this time, the soldering tin is heated into a molten liquid in the heating tank 72, which can be sprayed upward through the strip nozzle 75, and finally falls into the two recovery pools 73 after being guided by the left and right partitions 76 and the curled steel sheet 82. The tin liquid falling into the recovery pool 73 will flow back into the heating tank 72 through the connecting pipe 74 for reuse. The above work processes are all controlled by a computer, and the movement of the power strip component 2 grabbing the connector 38, the tray 35, the spraying of the flux, and the expansion area of ​​the curled steel sheet 82 are all electrically controlled. In the process of mutual cooperation of each component, all parameters are preset and adjustable.

[0021] Working principle: When using the present invention, firstly, the circuit board 37 to which the connector 38 needs to be welded is placed in the tray 35. According to different production needs, the tray 35 and the connector 38 can be replaced. At this time, the movable frame 22 is moved in the first track 21, and the pre-prepared material connector 38 is clamped by the electric gripper 26. Under the movement of the movable block 23 and the telescopic action of the first hydraulic rod 25, the material connector 38 is inserted into the reserved hole position of the circuit board 37. According to different needs of placement angle and position, the electric gripper 26 can also be driven to rotate by the rotation of the ring motor 24, and the insertion is completed under the movement of the first track 21 and the movable block 23; At this time, the electric wheel 34 is moved clockwise again, so that the tray 35 can move to the right along the second track 32, and stop when it reaches the top of the spraying component 4. The stepper motor 42 moves left and right on the screw rod 41, and under the rotation and extension of the mechanical arm 43, the circular nozzle 45 with the closed component 5 is moved to the position of the pins exposed by the opening 36 to spray the flux. During the process of spraying the flux, only the pins of the connector 38 exposed at the opening 36 can be in contact with the molten tin liquid for welding, and the rest of the circuit board 37 will not be tinned; When the circular nozzle 45 sprays upward, the multiple sealing plates 54 will be stressed and drive the multiple rectangular blocks 52 to move outward. At this time, the gaps between the multiple sealing plates 54 will become larger, allowing the flux to pass through. When the circular nozzle 45 stops spraying, the sealing plates 54 are no longer stressed. At this time, the annular spring 53 that was previously squeezed and deformed recovers its elastic potential energy and squeezes the multiple rectangular blocks 52 toward the middle of the circular ring 51 again. The multiple sealing plates 54 merge to complete the blocking. First, the spraying can be stopped quickly, and second, the problem of the flux that has been sprayed flowing back can be reduced. After the flux is sprayed, the tray 35 continues to move to the right in the second track 32, and stops when it moves to the closed component 5. The two second hydraulic rods 61 increase their strokes, driving the fixed box 62 upward, so that the two preheated first heating wires 63 and the second heating wires 64 can be as close to the pins where the flux has been sprayed as possible, so that the active ingredients in the flux can fully play a role. After the above preparations are completed, the tray 35 moves to the right again and reaches the circulation component 7 and the welding component 8. At this time, the soldering tin is heated into a molten liquid in the heating tank 72, and can be sprayed upward through the strip nozzle 75. After being guided by the left and right spacers 76 and the curled steel sheet 82, it finally falls into the two recovery pools 73. At this time, the molten tin liquid will form a flowing liquid plane with thickness. When the pins contact these tin liquids, they will directly adhere to complete the welding. The strip nozzle 75 is in the shape of an inverted trapezoidal strip liquid outlet. The molten tin liquid will be uniformly sprayed upward through the strip nozzle 75. The strip nozzle 75 itself does not change the physical shape, but only controls the flow rate and flow rate of the molten tin liquid sprayed upward. In conjunction with the extension area of ​​the curled steel sheet 82, the laying area of ​​the molten tin liquid can be adjusted; By adjusting the stroke of the third hydraulic rod 84 and the rotation of the second electric shaft 85 that cooperates with each other, the length of the curled steel sheet 82 extending to both sides can be changed. When the stroke of the third hydraulic rod 84 increases, the curled steel sheet 82 in the first electric shaft 81 will be pulled through the connecting piece 83 to extend it outward, thereby expanding the liquid area of ​​​​the molten tin. When the third hydraulic rod 84 shortens its stroke, the curled steel sheet 82 will be rewound around the outer edge of the first electric shaft 81, thereby reducing the welding area, and the tin liquid that falls into the recovery pool 73 will flow back into the heating tank 72 through the connecting pipe 74 for reuse. The above work processes are all controlled by a computer, and the power strip component 2 grabs the connector 38, the movement of the tray 35, the spraying of flux, and the expansion area of ​​the curled steel sheet 82 are all electrically controlled. In the process of mutual cooperation of each component, all parameters are preset and adjustable.
