The circuit board is the core part of the charger, on which various electronic components are integrated, such as transformers, rectifier diodes, capacitors, resistors, chips, etc. During the production of chargers, the welding between the PCB and each component is a relatively complex and crucial process.

Detailed implementation manners

[0032] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0033] Example 1, as Figure 1 shown, a welding auxiliary device for charger processing, including an operating table 1, a fixing component 6 is arranged at the rear side of the upper end of the operating table 1, a welding torch 2 is fixedly connected to the front side of the upper end of the operating table 1, a moving component 3 is arranged at the upper end of the operating table 1 on the left side of the fixing component 6, a blowing and sucking component 4 is arranged at the upper end of the operating table 1 on the left side of the moving component 3, and a cleaning component 5 is arranged above the moving component 3.

[0034] In the process of manufacturing chargers, especially during the soldering process of the internal PCB board and components of the charger, in order to make full use of the space of the PCB board, most of the internal PCB boards of chargers need to be soldered on both sides;

[0035] During the soldering process of the PCB board and components, first, the fixing component 6 is used to clamp and fix the PCB board. Then, the moving component 3 transports the fixing component 6, the PCB board to be soldered, and the components forward to below the soldering gun 2. During the transportation process, through the cooperation of the moving component 3 and the blowing and suction component 4, it is possible to blow air from above and suck air from below the PCB board, achieving the effect of cleaning small dust particles on the board;

[0036] Similarly, after soldering, through the cooperation of the cleaning component 5, the soldered side is sprayed with a cleaning agent to prevent the flux from affecting the operation of subsequent components. After spraying, through the cooperation of the fixing component 6 and the moving component 3, the PCB board can be flipped 180°, facilitating the placement of different components on the other side of the PCB board for soldering again.

[0037] The soldering gun 2 mentioned above is a conventional design in the prior art. The soldering gun 2 is electrically connected to the control terminal in the prior art. By presetting the operation path of the soldering gun 2 in advance, when the fixing component 6 drives the PCB board and components to be soldered to move below the soldering gun 2, the soldering gun 2 can operate automatically to achieve the soldering of the PCB board and components.

[0038] During the operation of this embodiment, through the cooperation of the moving component 3 and the blowing and suction component 4, during the transportation of the PCB board to below the soldering gun 2, air is blown from above and sucked from below, effectively removing dust and small particles on the PCB board. During the reset process, the airflow can also accelerate the volatilization of the cleaning agent. Through the cooperation of the cleaning component 5, the soldered side can be sprayed with a cleaning agent in time to remove the flux, avoiding the adverse impact of the flux on the operation of subsequent components. Through the cooperation of the moving component 3 and the fixing component 6, the PCB board can be flipped 180°, facilitating soldering on the other side again, reducing the turnover time of the PCB board between different processes, and making the entire soldering process more coherent and smooth.

[0039] Embodiment 2. On the basis of Embodiment 1, in order to achieve the effect of automatically flipping the PCB board and spraying and cleaning the soldering surface after soldering.

[0040] Refer to Figure 2 , in the middle of the upper end of the operating table 1, a guide rail 11 is fixedly connected. On the upper end of the operating table 1 on the right side of the guide rail 11, a drag chain 12 is fixedly connected. At the rear side of the upper end of the drag chain 12, a slide plate 13 is fixedly connected, and the slide plate 13 is slidably connected to the upper end of the guide rail 11.

[0041] The drag chain 12 mentioned above is a conventional design in the prior art. The drag chain 12 can flexibly bend and stretch with the reciprocating motion of the slide plate 13, providing reliable support and guidance for cables and pipes, ensuring that they will not be over-stretched, twisted or broken during movement, thereby ensuring the normal operation of the equipment.

[0042] Through the cooperation of the guide rail 11 and the slide plate 13, during the operation of the fixed component 6, the auxiliary drag chain 12 realizes the collection of the wiring harness and the like.

[0043] See also Figure 3 The moving assembly 3 includes a horizontal plate 31 fixedly connected to the upper end of the operating platform 1, a hydraulic cylinder 32 fixedly connected to the upper end of the operating platform 1 below the horizontal plate 31, a push plate 33 fixedly connected to the output end of the hydraulic cylinder 32, and an L-shaped rod 35 fixedly connected to the upper end of the push plate 33.

[0044] Specifically, after the PCB board is fixed, the hydraulic cylinder 32 can be activated, and then the output end of the hydraulic cylinder 32 pushes the push plate 33 forward, and the L-shaped rod 35 is driven to move in the same direction during the forward movement of the push plate 33.

[0045] See also Figure 3 The rear end of the horizontal part of the L-shaped rod 35 is fixedly connected with a rectangular plate 34, the middle part of the lower end of the rectangular plate 34 is fixedly connected to the upper end of the slide plate 13, the upper end of the horizontal plate 31 is fixedly connected with a limiting groove 36, and the left side of the lower end of the rectangular plate 34 is slidably connected to the upper end of the horizontal plate 31.

[0046] When the L-shaped rod 35 is driven by the push plate 33 to move forward, the rectangular plate 34 is driven to move in the same direction, and the cross plate 31 cooperates to limit the rectangular plate 34 .

[0047] See also Figures 4 - 7 The fixing assembly 6 includes a fixing cylinder 61 fixedly connected to the upper end of the rectangular plate 34, the inner surface of the fixing cylinder 61 is symmetrically connected to a fixing shaft 67 for rotation, two fixing shafts 67 are fixedly connected to a pneumatic clamp 66 at one end close to each other, a one-way rotating shaft 68 is arranged at the left end of the left fixing shaft 67, a rotating rod 62 is fixedly connected to the inner surface of the one-way rotating shaft 68, a rotating plate 63 is fixedly connected to the left side of the outer surface of the rotating rod 62, a rotating roller 65 is fixedly connected to the left end of the rotating plate 63, the outer surface of the rotating roller 65 is rotatably connected to a limiting roller 64, and the outer surface of the limiting roller 64 is slidably connected to the inner surface of the limiting groove 36.

[0048] The one-way rotating shaft 68 is a conventional design in the prior art. The one-way rotating shaft 68 cooperates with the rotating rod 62 and the fixed shaft 67, so that when the fixed cylinder 61 drives the rotating rod 62 and the two fixed shafts 67 to move forward, the rotating rod 62 rotates while the fixed shafts 67 do not rotate. When the fixed cylinder 61 drives the rotating rod 62 and the two fixed shafts 67 to move backward, the rotating rod 62, the one-way rotating shaft 68 and the fixed shaft 67 rotate 180° at the same time.

[0049] Refer to Figure 5 , when preparing to weld the PCB board and components, first use two pneumatic clamps 66 to clamp and fix the PCB board, and then the high-temperature-resistant components can be placed on the upper end of the PCB board to prepare for the first-side welding.

[0050] Furthermore, after the components are placed, activate the hydraulic cylinder 32 to operate. Then, the output end of the hydraulic cylinder 32 pushes the push plate 33 forward, driving the L-shaped rod 35, the rectangular plate 34, and the fixed cylinder 61 to move forward simultaneously to prepare for welding.

[0051] Refer to Figure 7 , during the process of the rectangular plate 34 driving the fixed cylinder 61 to move forward, the rotating rod 62, the rotating plate 63, the limiting roller 64, and the rotating roller 65 are driven to move in the same direction. Among them, the limiting roller 64 slides forward along the inner surface of the limiting groove 36 during the movement.

[0052] When the limiting roller 64 slides forward along the inner surface of the limiting groove 36, when the limiting roller 64 slides to the rear arc part of the inner surface of the limiting groove 36, at this time, the limiting roller 64 slides downward along the arc part of the limiting groove 36. At the same time, the rotating rod 62, the rotating plate 63, and the rotating roller 65 are driven by the fixed cylinder 61 to move horizontally forward. Through the limitation of the limiting roller 64 by the arc part of the limiting groove 36, the rotating rod 62, the rotating plate 63, and the rotating roller 65 as a whole rotate forward around the axis of the limiting roller 64;

[0053] Furthermore, through the cooperation of the entire arc part of the limiting groove 36, the rotating roller 65, the rotating plate 63, and the rotating rod 62 as a whole rotate forward 180° around the axis of the limiting roller 64.

[0054] Similarly, through the cooperation of the one-way rotating shaft 68, when the fixed cylinder 61 drives the PCB board forward to prepare for welding, the rotating rod 62, the rotating plate 63, and the rotating roller 65 rotate 180° around the axis of the limiting roller 64, while the fixed shaft 67 and the pneumatic clamp 66 do not rotate.

[0055] Then, when the fixed cylinder 61 is driven forward by the rectangular plate 34 to below the welding torch 2, at this time, the limiting roller 64 is located at the front side of the inner surface of the limiting groove 36. Activate the welding torch 2 to make the welding torch 2 weld the PCB board and components according to the preset path.

[0056] After the welding is completed, the output of the hydraulic cylinder 32 drives the push plate 33, the L-shaped rod 35, and the rectangular plate 34 to reset. During the reset process of the rectangular plate 34, it drives the fixed cylinder 61, the rotating rod 62, the two fixed shafts 67, the pneumatic clamp 66, and the clamped PCB board to move backward;

[0057] Furthermore, refer to Figure 7, when the limiting roller 64 moves backward to the arc part of the inner surface of the limiting groove 36, through the cooperation of the limiting roller 64 and the limiting groove 36, the rotating rod 62, the rotating plate 63 and the rotating roller 65 rotate backward by 180° around the axis of the limiting roller 64. At the same time, through the cooperation of the one-way rotating shaft 68, the fixed shaft 67 drives the pneumatic clamp 66 and the clamped PCB board to rotate by 180° simultaneously, so that the un-welded side of the PCB board faces upward, preparing for the welding of heat-sensitive components and large components.

[0058] Refer to Figure 8 and Figure 9 , the blowing and suction assembly 4 includes an airbag one 41 fixedly connected to the rear end of the push plate 33. The rear end of the airbag one 41 is fixedly connected with a vertical plate one 411. The outer surface of the airbag one 41 is fixedly connected with a hose one 42. One end of the hose one 42 far from the airbag one 41 is fixedly connected with an annular pipe 43. The annular pipe 43 is fixedly connected with the bottom wall of the inner surface of the fixed cylinder 61. A multi-layer board 44 is fixedly connected to the middle of the inner surface of the fixed cylinder 61. The lower end of the vertical plate one 411 is fixedly connected with the upper end of the operating table 1.

[0059] The above-mentioned multi-layer board 44 is a conventional design in the prior art. At the same time, the multi-layer board 44 is composed of a viscous layer, an adsorption layer and an anti-static layer compounded from top to bottom. The surface of the viscous layer has low-viscosity adhesion, directly contacts dust particles, captures solid particles through physical adhesion, and at the same time, honeycomb-shaped pores are provided in the viscous layer, and the pores allow liquid cleaning agents such as isopropyl alcohol to penetrate downward through the pores; the adsorption layer is located below the viscous layer, adsorbs the penetrated liquid solvent through a high specific surface area, and at the same time, the adsorption layer is provided with gradient honeycomb pores, and the honeycomb pores gradually shrink from the viscous layer to the anti-static layer; the anti-static layer is internally embedded with a woven structure of conductive fibers to form a conductive mesh path, evenly dispersing static charges to avoid local accumulation, realizing the anti-static function through the conductivity of the material itself, avoiding adverse effects of static electricity on components during the welding of the PCB board. At the same time, the anti-static layer is integrally arranged in a honeycomb shape, and conductive contacts are arranged at the honeycomb nodes to ensure the connection of the conductive networks of each unit. The honeycomb structure will not affect the effects of each layer, and at the same time, it also has a breathable effect.

[0060] Several nozzles are arranged on the upper part of the outer surface of the above-mentioned annular pipe 43, and the inner surfaces of the several nozzles, the inside of the annular pipe 43, the hose one 42 and the inside of the airbag one 41 are connected in communication.

[0061] During the process of the fixed cylinder 61 driving the PCB board to move forward for welding, the push plate 33 moves forward, driving the airbag one 41 to be stretched. At this time, the air pressure inside the airbag one 41 becomes lower, and the gas inside the fixed cylinder 61 enters the inside of the airbag one 41 through several nozzles on the outer surface of the annular pipe 43.

[0062] Refer to Figure 9, a push plate 33 is fixedly connected to the front end of an electric telescopic rod 47, the front end of the electric telescopic rod 47 is fixedly connected to a second slide plate 46, the front end of the second slide plate 46 is fixedly connected to a second airbag 45, the front end of the second airbag 45 is fixedly connected to a second vertical plate 451, and a second hose 48 is fixedly connected to the outer surface of the second airbag 45. One end of the second hose 48 away from the second airbag 45 is fixedly connected to a spray ring 49. The lower end of the second slide plate 46 is slidably connected to the upper end of the operating table 1, and the lower end of the second vertical plate 451 is fixedly connected to the upper end of the operating table 1.

[0063] The above-mentioned electric telescopic rod 47 is a conventional setting in the prior art. At the same time, the electric telescopic rod 47 is electrically connected to a control terminal in the prior art. During the operation of the electric telescopic rod 47, through presetting, the electric telescopic rod 47 is kept in a stretched state and does not move when the electric telescopic rod 47 is just pushed. After moving a certain distance, the electric telescopic rod 47 begins to be compressed.

[0064] A plurality of nozzles are obliquely arranged on the inner surface of the above-mentioned spray ring 49, and the inner surfaces of the plurality of nozzles, the inner surface of the spray ring 49, the second hose 48 and the inner surface of the second airbag 45 are communicated with each other.

[0065] When the push plate 33 moves to drive the rectangular plate 34, the fixed cylinder 61, the PCB board and the components to move forward, it will push the electric telescopic rod 47 forward. At this time, the electric telescopic rod 47 is set to maintain an extended state. Immediately, the electric telescopic rod 47 pushes the second slide plate 46 forward. The second slide plate 46 slides forward along the upper end of the operating table 1, and at the same time squeezes the second airbag 45. As a result, the air pressure inside the second airbag 45 increases. The gas inside the second airbag 45 enters the inside of the spray ring 49 through the inside of the second hose 48 and is sprayed from the plurality of nozzles on the inner surface of the spray ring 49 onto the upper end of the PCB board inside the fixed cylinder 61;

[0066] By spraying air onto the upper end of the PCB board through the spray ring 49 and the plurality of nozzles and sucking air from below the PCB board through the annular pipe 43 and the plurality of nozzles, the dust and small particles on the upper end of the PCB board are blown up and flow downward through the air flow. During the process of the dust and small particles flowing downward with the air flow, they will be adsorbed by the adhesive layer on the upper end of the multi-layer board 44.

[0067] When the push plate 33 pushes the electric telescopic rod 47 and the second slide plate 46 to squeeze the second airbag 45 forward, when the fixed cylinder 61 is about to move below the welding torch 2, at this time, the second airbag 45 is compressed to the maximum extent. Immediately, when the push plate 33 continues to push forward, at this time, the electric telescopic rod 47 is compressed, so that the push plate 33, the rectangular plate 34, the fixed cylinder 61 and other structures drive the PCB board to move forward to below the welding torch 2 to prepare for welding.

[0068] Both the above-mentioned first airbag 41 and the second airbag 45 are made of polyurethane commonly used in the prior art, and can ensure that the first airbag 41 and the second airbag 45 can still be stably sealed during repeated expansion and contraction.

[0069] See also Figure 10 and Figure 11 The cleaning component 5 includes a fixed block 51 fixedly connected to the upper end of the horizontal plate 31, a plurality of springs 58 are fixedly connected to the rear end of the fixed block 51, a slide plate 3 52 is fixedly connected to the rear ends of the plurality of springs 58, the lower end of the slide plate 3 52 is slidably connected to the upper end of the horizontal plate 31, a liquid capsule 53 is fixedly connected to the rear end of the slide plate 3 52, a vertical plate 3 54 is fixedly connected to the rear end of the liquid capsule 53, a hose 3 55 is fixedly connected to the outer surface of the liquid capsule 53, a nozzle 56 is fixedly connected to the end of the hose 3 55 away from the liquid capsule 53, a fixed rod 57 is fixedly connected to the left end of the nozzle 56, and the left side of the lower end of the fixed rod 57 is fixedly connected to the upper end of the limiting groove 36.

[0070] The above-mentioned liquid capsule 53 is connected with an external cleaning agent liquid source, and a one-way valve is provided at the connecting part, so that the cleaning agent can only flow into the liquid capsule 53 through the liquid source. At the same time, a plurality of nozzles are obliquely provided on the outer surface of the nozzle 56, wherein the plurality of nozzles are connected with the nozzle 56, the hose three 55 and the inside of the liquid capsule 53. At the same time, a one-way valve is provided at the connecting part between the inside of the hose three 55 and the liquid capsule 53, so that the cleaning agent in the liquid capsule 53 can only flow out from the hose three 55, and gas or liquid cannot flow into the inside of the liquid capsule 53 from the hose three 55 in the reverse direction.

[0071] The push plate 33 drives the rectangular plate 34, the fixing cylinder 61 and the PCB board forward to prepare for welding. When the rectangular plate 34 moves to the point where the front end of the rectangular plate 34 is in close contact with the rear end of the sliding plate 3 52, the rectangular plate 34 continues to move forward, and then pushes the sliding plate 3 52 to slide forward, thereby compressing the springs 58. At this time, the liquid capsule 53 is also driven by the sliding plate 3 52 to continuously stretch.

[0072] When the liquid capsule 53 is stretched, the pressure inside the liquid capsule 53 decreases, and then the liquid capsule 53 absorbs the detergent from the external detergent liquid source.

[0073] After the welding gun 2 finishes welding the first side of the PCB board, the output end of the hydraulic cylinder 32 drives the push plate 33 and the L-shaped rod 35 and other structures to move backward, and then the rectangular plate 34 no longer continues to squeeze the slide plate 3 52. At this time, several compressed springs 58 push the slide plate 3 52 backward and then squeeze the liquid capsule 53, so that the cleaning agent in the liquid capsule 53 is sprayed from the inside of the hose 3 55 to the several nozzles on the outer surface of the nozzle 56 toward the upper end of the welded PCB board, so as to clean the flux used in the welding process in time to avoid the problem of subsequent PCB board operation failure caused by the flux not being cleaned up.

[0074] As the fixed cylinder 61 drives the welded PCB board to move backward, the cleaning agent sprayed by the nozzle 56 is evenly distributed on the upper end of the PCB board. After the rectangular plate 34 moves backward and disengages from the slide plate three 52, the spring 58 no longer pushes the slide plate three 52 to move. At the same time, the upper end of the PCB board is also evenly sprayed with the cleaning agent. Then, the cleaning agent fully reacts with the soldering flux and other substances. When the limit roller 64 moves to the arc part of the limit groove 36, the cleaning agent has fully mixed with the impurities such as the soldering flux waiting to be cleaned. During the process of the fixed shaft 67 driving the pneumatic clamp 66 and the PCB board to flip 180°, the excess cleaning agent falls on the upper end of the multilayer board 44 as it flips and is adsorbed by the adsorption layer of the multilayer board 44, without affecting the operation of other structures.

[0075] Similarly, after welding is completed, during the process of the push plate 33 moving backward to drive the fixed cylinder 61 and the PCB board to reset, the electric telescopic rod 47 is in a compressed state and is driven backward by the push plate 33. During the backward movement of the electric telescopic rod 47, it drives the rear ends of the slide plate two 46 and the airbag two 45 to move backward simultaneously, allowing the gas at the upper end of the PCB board inside the fixed cylinder 61 to enter the airbag two 45 through the spray ring 49 and the hose two 48, guiding the air to flow outward;

[0076] At the same time, during the backward movement of the push plate 33, the airbag one 41 is continuously squeezed. The gas inside the airbag one 41 is blown upward through the hose one 42 and the annular pipe 43, and in cooperation with the honeycomb pores inside the multilayer board 44, the gas blown out by the annular pipe 43 is evenly dispersed, which can dry the cleaning agent on the surface of the flipped PCB board, and at the same time, the dust adsorbed on the upper end of the multilayer board 44 will not be blown up.

[0077] When the electric telescopic rod 47 drives the slide plate two 46 to move backward until the slide plate two 46 is stretched to the maximum, the push plate 33 continues to pull the electric telescopic rod 47 to reset. At this time, the slide plate two 46 is no longer stretched, and the electric telescopic rod 47 is gradually stretched.

[0078] After the push plate 33 drives the rectangular plate 34 and the fixed cylinder 61 and other structures to reset, heat-sensitive components are placed on the upward-facing side of the PCB board again, and the above steps are repeated to prepare for the welding of the second side.

[0079] After welding on both sides is completed, the clamping and fixing of the PCB board by the two pneumatic clamps 66 are released, and an un-welded PCB board is placed to prepare for the next welding.

[0080] Therefore, through the cooperation of the limiting groove 36 and the limiting roller 64 and other structures, after the welding is completed, this solution can not only automatically flip the PCB board by 180°, facilitating the welding of both sides of the PCB board, but also cooperate with the liquid sac 53 and other structures to achieve the purpose of spraying a cleaning agent on the welded PCB board for cleaning. At the same time, during the welding process, air is sucked from below the PCB board and blown from above the PCB board through the annular pipe 43 and the spray ring 49 and other structures, so as to blow up the dust and small particles at the upper end of the PCB board, and the airflow flows downward and is adsorbed and fixed by the multilayer board 44, thus ensuring the cleanliness of the welding environment. During the reset process, it can also achieve the effect of drying the cleaning agent on the PCB board, which is beneficial to ensuring the dryness and cleanliness of the PCB board.
