Description

Technical Field

[0001] The present invention relates to the technical field of welding cooling, and particularly to a component for a modular automated device. Background Art

[0002] With the continuous update and upgrade of electronic products, Surface Mount Technology (SMT for short) has become the mainstream of electronic manufacturing. In order to improve production efficiency and safety, more and more companies have chosen the automation and modularization of SMT production lines. The modular automated SMT production line can reconfigure each production function module of the production line according to actual needs. In the SMT production line, it mainly includes four steps: stencil printing, chip mounter, reflow soldering, and inspection. These four steps respectively include multiple function modules. Among them, reflow soldering is a process of putting the PCB board into a reflow soldering machine, melting the solder through high-temperature heating, and wetting the pads, component ends, and pins to form solder joints.

[0003] The key to reflow soldering lies in the control of the heating and cooling processes. The existing reflow soldering cooling technology uses an internal fan for cooling and heat dissipation. Its cooling effect is poor and the cooling speed is slow, resulting in the failure to cool the PCB board in time after soldering, causing the solder joints to have low brightness and being prone to phenomena such as fracture and peeling. Moreover, the cooling unit in the soldering equipment usually has gaseous combustion aids (rosin) remaining. Once the temperature drops, the gaseous rosin will liquefy. The liquefied rosin may adhere to the surface of the equipment, affecting the heat dissipation efficiency, and even dripping onto the surface of the PCB board, affecting the quality of the product.

[0031] Thirdly, the present invention is described in detail in conjunction with schematic diagrams. When detailing the embodiments of the present invention, for the convenience of explanation, the cross-sectional views showing the device structure will be locally enlarged out of the general proportion, and the schematic diagrams are only examples, which should not limit the scope of protection of the present invention herein. In addition, in actual production, three-dimensional spatial dimensions including length, width, and depth should be included.

[0032] Embodiment 1 Referring to Figures 1 to 3 , for the first embodiment of the present invention, a component for a modular automated device is provided, including a housing 100, on the inner side of the housing 100, a first conveyor rail 200 and a second conveyor rail 300 with different heights are fixedly arranged respectively, and a conveyor belt 400 is rotatably arranged on the inner sides of the first conveyor rail 200 and the second conveyor rail 300, and a commutation component 500 for changing the conveying direction of the PCB board, which includes a rail member 501 arranged on the opposite side of the first conveyor rail 200 and the second conveyor rail 300 on the inner side of the housing 100, a first turning member 502 arranged at one end of the rail member 501 close to the first conveyor rail 200, and a second turning member 503 arranged at one end of the rail member 501 close to the second conveyor rail 300; a cooling component 600 for cooling the welded PCB board and eliminating the influence of rosin on the PCB board, which includes an absorption member 601 arranged on the top of the housing 100, a cooling member 602 arranged on the inner side of the housing 100, and a processing member 603 arranged inside the cooling member 602, and the processing member 603 is used for cooling the air.

[0033] During use: When this device is in use, it is connected to a soldering furnace. The PCB board after soldering is transported to the first conveyor rail through the conveyor belt 400, and then the conveying direction is changed by the commutation component 500, from being placed flat to being placed vertically and moving downward. In this process, the PCB board moves downward, while the hot air of the soldering furnace moves upward, so that the PCB board and the hot air flow containing rosin molecules are initially separated. Then the cooling member 602 cools the PCB board.

[0034] Embodiment 2 Referring to Figures 4 to 6, which is the second embodiment of the present invention. The difference between this embodiment and the first embodiment is that the rail member 501 includes a vertical rail 501a, a damping wheel 501b, and a rubber wheel 501c. One end of the vertical rail 501a is fixedly arranged at the end of the first transfer rail 200, and the other end is fixedly arranged at one end of the second transfer rail close to the first transfer rail 200. Moreover, the vertical rail 501a is perpendicular to both the first transfer rail 200 and the second transfer rail 300. A plurality of damping wheels 501b are arranged and rotatably arranged in the middle part of the vertical rail 501a, and a plurality of rubber wheels 501c are arranged and rotatably arranged at one end of the vertical rail 501a close to the second transfer rail 300.

[0035] Among them, the damping wheel 501b has a wide range of applications in many engineering fields, such as machinery, aerospace, automobiles, etc. It is used to absorb and reduce vibrations, provide smooth movement, and at the same time reduce noise. In this device, it has a certain clamping effect on the PCB board and is mainly used to slow down the sliding speed of the PCB board.

[0036] The vertical rail 501a is divided into multiple sections. Among them, only one side close to the first transfer rail is equipped with a baffle at one end of the vertical rail 501a close to the first turning member 502, and only one side close to the second transfer rail is equipped with a baffle at one end of the vertical rail 501a close to the second rotating member. Both sides of the middle part of the vertical rail 501a where the damping wheel 501b is installed are equipped with baffles.

[0037] The first turning member 502 includes a first fixed platform 502a, a first rotating column 502b, a first clamping groove 502c, a T-shaped groove 502d, a spring 502e, and a clamping block 502f. The first fixed platform 502a is fixedly arranged on the side of the first transfer rail 200, the first rotating column 502b is rotatably arranged on the side of the fixed platform, the first clamping groove 502c is opened on the end face of the first rotating column 502b, the T-shaped groove 502d is opened inside the first clamping groove 502c, the spring 502e is fixedly arranged inside the T-shaped groove 502d, and the clamping block 502f is slidably arranged inside the T-shaped groove 502d and fixedly arranged at the end of the spring 502e.

[0038] Among them, a torsion spring is connected inside the first rotating column 502b and the first fixed platform 502a. After the PCB board slides out of the first clamping groove 502c, the first rotating column 502b can be reset by the elastic force of the torsion spring.

[0039] The second steering member 503 includes a fixed table 503a, a rotating column 503b, a clamping groove 503c, a limit block 503d, a rotating shaft 503e, a toggle plate 503f and an arc plate 503g. The fixed table 503a is fixedly arranged at one end of the second conveying rail 300 close to the vertical rail 501a, the rotating column 503b is rotatably arranged on the side of the fixed table 503a, the clamping groove 503c is opened on the end face of the rotating column 503b, and the limit block 503d is provided with two pieces and is respectively fixedly arranged on the side of the fixed table 503a and the side of the rotating column 503b.

[0040] Among them, a torsion spring is connected between the second rotating column 503b and the second fixed platform 503a. After the PCB board slides out of the second clamping groove 503c, the second rotating column 503b can use the elastic force of the torsion spring to reset to form a continuous assembly line operation.

[0041] The rotating shaft 503e is rotatably set on the inner side of the outer shell 100, the toggle plate 503f is fixedly set on the side of the rotating shaft 503e, the arc plate 503g is located above the rotating shaft 503e and fixedly set on the inner side of the outer shell 100, and the rotating shaft 503e is connected to the rotating roller of the inner conveyor belt 400 of the second conveyor rail 300 through a gear belt.

[0042] When in use: In the device, the PCB board starts from the first conveying rail 200. As the conveyor belt 400 rotates, the two sides of the PCB board slide into the inner side of the clamping groove 502c and squeeze the clamping block 502f. The clamping block 502f overcomes the elastic force of the spring 502e and slides and clamps the PCB board. However, under the pushing effect of the conveyor belt 400, the PCB board can still overcome the resistance between the clamping block 502f and continue to move forward. As the PCB board moves forward, when half of it exceeds the position of the rotating column and the other half slides out of the first conveying rail 200, the PCB board is in an eccentric state, and then due to the gravity, it overcomes the torsion spring to drive the rotating column 502b to flip downward, and finally abuts on one side of the vertical rail 501a. It is worth noting that during the flipping process of the PCB board, due to the clamping of the clamping block 502f, the PCB board is constrained and will not be thrown out of the clamping groove 502c during the flipping process.

[0043] After the PCB board flips over, its own gravity is enough to overcome the clamping force of the clamping block 502f and slide down, and finally contact the damping wheel 501b. The damping wheel 501b reduces the speed of the PCB board sliding down, thereby increasing the contact time between the PCB board and the cooling assembly 600, so as to improve the cooling effect of the cooling member 602. After sliding out of the damping wheel 501b, the PCB board slides into between the rubber wheels 501c. Since the vertical rail 501a of this part has only one side, the PCB board can easily slide out from the side of the vertical rail 501a without the baffle, and the rubber wheel 501c can just clamp the PCB board, so that the PCB board will not slide out of the vertical rail 501a during the normal falling process.

[0044] During the descent of the side of the rubber wheel 501c, the PCB board will gradually slide into the inner side of the second clamping groove 503c, and the rotating shaft 503e is driven by the rotating roller of the conveyor belt 400 to rotate, and the toggle plate 503f rotates with the rotating shaft 503e and hits the side of the PCB board, so that the PCB board flips again. During the flipping process, the side of the PCB board away from the toggle plate 503f abuts against the curved plate 503g and slides along the side of the curved plate 503g, and the toggle plate 503f forms a support for the PCB board to prevent the PCB board from sliding out of the second conveyor rail 300. Since the curved surface of the curved plate 503g gradually approaches the second conveyor rail 300, the PCB board is also moved closer to the second conveyor rail 300 as the curved surface of the curved plate 503g changes. When the PCB board is completely flat under the action of gravity, its side also just slides between the conveyor belt 400 and the transmission rail, and is continuously pushed by the conveyor belt 400.

[0045] Among them, the limit plate is used to limit the relative rotation angle between the second rotating column 503b and the second fixed seat. When the PCB board is in a flat state, the limit block 503d on the side of the second fixed seat and the second rotating shaft 503e just contacts, and the PCB board stops rotating, thereby preventing the PCB board from rotating toward the side away from the second conveying rail 300.

[0046] The main function of the reversing component 500 is to change the PCB board from horizontal one-way movement to vertical downward movement, thereby realizing the separation of the PCB board and the hot air flow containing rosin molecules.

[0047] The remaining structures are the same as those of Example 1.

[0048] Example 3 Reference Figures 4 to 9, which is the third embodiment of the present invention. The difference between this embodiment and the second embodiment is that the absorbent member 601 includes a receiving shell 601a, an absorption pump 601b, and an air suction pipe 601c. The receiving shell 601a is communicatively disposed at the top of the outer shell 100. The receiving shell 601a is located at the top of the outer shell 100 near the first commutation member. The suction port of the absorption pump 601b is communicatively connected to the top of the receiving shell 601a. The air suction pipe 601c is located at the top of the first transfer rail 200 and is communicatively connected to the top of the outer shell 100. There are multiple air suction pipes 601c, and they are all communicatively connected to the receiving shell 601a through pipes. The absorption pump 601b can absorb the gas from the receiving shell 601a and the air suction pipe 601c and discharge it through the air outlet.

[0049] The cooling member 602 includes a fixing cylinder 602a, an air inlet pipe 602b, an air suction pump 602c, an air suction cavity 602d, an air supply pipe 602e, an air blowing pump 602f, and an air supply cavity 602g. The fixing cylinder 602a is located on one side of the vertical rail 501a and is fixedly disposed inside the outer shell 100 through a bracket. The air inlet pipe 602b is communicatively disposed at the bottom of the fixing cylinder 602a. The air outlet of the air suction pump 602c is communicatively connected to one end of the air inlet pipe 602b away from the fixing cylinder 602a. The air suction cavity 602d is communicatively connected to the air inlet of the air suction pump 602c. The air supply pipe 602e is communicatively disposed at the top of the fixing cylinder 602a. The air inlet of the air blowing pump 602f is communicatively connected to one end of the air supply pipe 602e away from the fixing cylinder 602a. The air supply cavity 602g is communicatively connected to the air outlet of the air blowing pump 602f.

[0050] The air supply cavity 602g is located directly above the air suction cavity 602d. There are two sets of the air suction cavity 602d and the air supply cavity 602g, and they are symmetrically disposed on both sides of the vertical rail 501a. The air suction cavity 602d away from the fixing cylinder 602a is communicatively connected to the air inlet of the air suction pump 602c through a pipe. The air supply cavity 602g away from the fixing cylinder 602a is communicatively connected to the air outlet of the air blowing pump 602f through a pipe.

[0051] The processing part 603 includes a partition plate 603a, an inner cylinder 603b, a vent hole 603c, a spiral plate 603d, a ventilation pipe 603e, an impact arc plate 603f, and a water replacement port 603g. The partition plate 603a is fixedly arranged inside the fixed cylinder 602a and divides the fixed cylinder 602a into upper and lower parts. The lower part of the fixed cylinder 602a is filled with cooling water. The inner cylinder 603b is fixedly arranged on the top of the partition plate 603a and is coaxially arranged with the fixed cylinder 602a. The vent hole 603c is opened on the surface of the partition plate 603a and is located between the inner cylinder 603b and the fixed cylinder 602a. The spiral plate 603d is fixedly arranged between the inner cylinder 603b and the fixed cylinder 602a. The intake pipe 602b penetrates into the interior of the fixed cylinder 602a and extends to the upper half of the fixed cylinder 602a. A plurality of ventilation pipes 603e are arranged and communicated with the end of the intake pipe 602b. The end of the ventilation pipe 603e away from the intake pipe 602b penetrates the partition plate 603a and extends to the lower half of the fixed cylinder 602a. The impact arc plate 603f is located directly below the air outlet of the ventilation pipe 603e and is fixedly arranged on the inner bottom of the fixed cylinder 602a through a bracket. A large number of uniformly arranged grooves are opened on the surface of the impact arc plate 603f. The water replacement port 603g is opened at the bottom of the fixed cylinder 602a for replacing the cooling water in the fixed cylinder 602a.

[0052] During use: In the prior art, during the reflow soldering process of the PCB board, both soldering and cooling are on the transportation track at the same height, which causes the hot air flow with rosin molecules to diffuse into the cooling device. Once the rosin gas cools in the cooling chamber, it will liquefy, and then adhere to the inner wall of the cooling chamber and drip onto the PCB board, having a negative impact on production.

[0053] Under the action of the commutation assembly 500, the PCB board changes from lying flat and moving unidirectionally to moving vertically downward, and the hot air flow with rosin will flow upward. After separating from the PCB board, these hot air flows accumulate inside the accommodation chamber, and then are discharged from the housing 100 through the absorption pump 601b. And under the suction of the absorption pump 601b, the suction pipe 601c starts to absorb the hot air flow into the accommodation chamber during the transportation of the PCB to the cooling device, preventing the accumulation of hot air flow above the first transfer rail 200, and thus avoiding the liquefaction of the rosin in this part of the hot air flow due to being close to the cooling part 602.

[0054] On both sides of the vertical rail 501a, since it is connected to the air blowing pump 602f, the air supply chamber 602g blows out cold air to cool the PCB board, while the air suction chamber 602d absorbs the air flow that has been heated due to absorbing the heat of the PCB board on the lower side of the PCB board, thereby forming a circulating air flow to continuously cool the PCB board. Among them, the air suction chamber 602d has suction due to being connected to the air suction pump 602c. The air suction pump 602c transports the hot air flow in the air suction chamber 602d through the intake pipe 602b to the ventilation pipe 603e, and then transports it to the cooling water in the lower half of the fixed cylinder 602a by the ventilation pipe 603e. After the hot air flow comes into contact with the cooling water, a large number of bubbles are generated. A small part of these bubbles dissolves in the cooling water, and most of them will float to the surface of the cooling water and finally escape from the cooling water. However, during the floating process, heat exchange occurs between the hot air and the cooling water, and the temperature decreases. The cold air flow after escaping passes through the ventilation holes 603c and the spiral plate 603d, and then is blown into the air supply chamber 602g by the air blowing pump 602f through the air supply pipe 602e, thereby forming a cold air flow blowing towards the PCB board.

[0055] In the fixed cylinder 602a, the hot air flow directly contacts the cooling water, which has a higher heat exchange efficiency compared to traditional heat exchangers. However, in order to prevent the cooling water from being absorbed into the air supply pipe 602e, the efficiency of the air suction pump 602c is set higher than that of the air blowing pump 602f. Among them, when the hot air flow is sprayed into the water from the ventilation pipe 603e, a water flow containing a large number of bubbles will be stirred up. This water flow will then collide with the grooves on the surface of the impact arc plate 603f, thereby stirring up more and smaller bubbles. The heat exchange speed between the hot air in the small bubbles and the cooling water is faster, thereby achieving the effect of improving the heat exchange efficiency. When the cooling water absorbs heat, evaporation will occur to generate water vapor. When this part of the water vapor rises with the cold air flow, it will liquefy again due to temperature reduction. The spiral plate 603d increases the contact process between the water vapor and the cold air flow, enabling more water vapor to liquefy, thereby preventing the water vapor from escaping from the fixed cylinder 602a and avoiding the pollution of the PCB board by the water vapor.
