Description

Technical Field

[0001] The present invention relates to the technical field of circuit board soldering, and particularly relates to a PCB circuit board production soldering device and a method thereof. Background Art

[0002] In the process of producing a PCB circuit board, it is often necessary to install electronic components on the surface of the circuit board, and then perform soldering on the pins of the electronic components and the circuit board. Since the soldering points of the pins and the mounting surfaces of the components are located on both sides of the circuit board respectively, it is necessary to turn the circuit board over after installing the components to make the pins face up. When turning over the circuit board, the components are likely to move downward under their own gravity, resulting in the components not being in close contact with the circuit board, and thus the soldered components fall off, affecting the soldering quality. Moreover, since there are many components on the surface of the circuit board, it is easy to miss placing or under placing components during installation, and automatic detection of the components cannot be performed, resulting in the soldered circuit board being prone to missing parts.

[0014] A method for using a PCB circuit board production welding device comprises the following steps: S1. When welding the circuit board, place the circuit board and the electronic components aligned with the circuit board on the unloading table from the left side, then control the motor to drive the turntable to rotate, and the turntable drives the flippable unloading assembly to rotate. When the second gear and the gear rod are transmitted, the second gear drives the connecting shaft to rotate, and the connecting shaft drives the rotating member to rotate. The rotating member squeezes the convex ball out of the fixed port and squeezes the first spring. At the same time, the rotating member drives the shell cover to flip, so that the pressing sheet contacts the electronic components and is subjected to continuous pressure, so that the pressing sheet drives the support rod to move, and the support rod compresses the second spring. The liquid in the shell cover is pressed into the side shell, and the second piston and the magnet are driven to move by hydraulic pressure. When the magnet corresponds to the disk, the magnetic repulsion between the magnet and the disk drives the movable rod to move, and at the same time compresses the third spring, so that the movable rod presses the second switch, and at the same time the first switch is pressed by the unloading table, and the alarm is turned off at this time. When the magnet does not correspond to the disk, the first switch is pressed by the unloading table, so that the alarm sounds an alarm. When the shell cover is closed, the first spring drives the convex ball to reset and snap into the fixed port to limit the rotating member. S2. Then continue to rotate the position of the feeding table. When the roller enters the arc surface of the arc-shaped plate, the arc-shaped plate squeezes the roller to drive the slide bar to move upward, compressing the fourth spring by the roller. Moreover, the slide bar drives the toothed plate to engage with the first gear, and the first gear drives the rotating shaft and the feeding table to rotate, causing the positions of the shell cover and the feeding table to be flipped and switched. After flipping, the welding surface of the circuit board is presented. When the circuit board is located at the position of the welding device, the circuit board and electronic components are then welded by the welding device. S3. After welding, make the circuit board continue to move in a circular motion, causing the roller to disengage from the arc-shaped plate. The fourth spring drives the slide bar to reset downward, enabling the toothed plate to engage with the first gear, and further causing the feeding table and the shell cover to complete the flipping and reset. When the second gear passes another toothed rod, the connecting shaft drives the shell cover to flip and open through the rotating part. At this time, the second spring drives the first piston to reset upward, the pressing piece is reset, the second piston is reset hydraulically, the magnet separates from the magnetic disk, and the third spring drives the magnetic disk and the movable rod to reset. The movable rod disengages from the second switch. When the circuit board is transferred to the left side, the circuit board is taken out through the material taking port, and at the same time, the circuit board to be welded is placed to perform a new round of welding operation.

[0015] Compared with the prior art, the present invention provides a PCB circuit board production and welding device and method, having the following beneficial effects: 1. For the PCB circuit board production and welding device and method, the feeding function of the circuit board can be realized through the feeding component. At the same time, the rotating component moves along. When the rotating component engages with the toothed rod, the rotating component drives the shell cover to flip and close with the feeding table. At the same time, the pressing component contacts the electronic components and applies pressure, so as to realize the close fitting of the electronic components and the circuit board. When the roller is squeezed by the arc-shaped plate, the linkage component engages with the first gear, causing the feeding table and the shell cover to be flipped and switched, so that the welding surface of the circuit board faces upward. At the same time, the stable connection between the electronic components and the circuit board can be maintained. After the circuit board is automatically flipped, it is convenient for the subsequent welding device to perform the welding operation. At the same time, after welding, the linkage component disengages from the arc-shaped plate, and the positions of the feeding table and the shell cover can be switched again to complete the reset. At the same time, when the transmission component engages with the toothed rod again, the shell cover automatically flips and opens, facilitating material taking.

[0016] 2. The PCB circuit board production and soldering device and its method. By flipping the shell cover, the pressing piece presses on the electronic component, and through continuous pressing, the pressing piece drives the support rod and the first piston to move. The first piston presses the liquid into the side shell, so that the hydraulic pressure drives the second piston and the magnet to move. When the magnet fails to correspond to the position of the disk, the first switch is pressed by the feeding table at this time to achieve the function of alarming. In this way, it can be checked whether there are problems with the installation of the electronic component or the problem of missing placement, so as to achieve the purpose of automatic detection. When the magnet corresponds to the disk, the magnetic repulsion between the magnet and the disk can drive the movable rod to press the second switch, so that the alarm stops alarming. In this way, it can be known that the electronic component is installed in place.

[0017] 3. The PCB circuit board production and soldering device and its method. By arranging several pressing components, each pressing piece can correspond to electronic components at different positions. When the pressing piece contacts the electronic component, it can smoothly press the first piston through the support rod. Then, through the hydraulic pressure, the second piston can be driven to drive the magnet to correspond to the disk, and the purpose of the movable rod pressing the second switch is achieved through the magnetic repulsion between the two, so as to detect whether the electronic component is installed in place. And the movable frame can slide on the guide rod, so that the position of the disk can be adjusted. With the setting of multiple pressing pieces, it can be adapted to different electronic component circuit boards, and then the detection operation of different circuit boards can be realized. Moreover, through the feeding component for feeding, the feeding process can make the rotating component and the toothed rod rotate to achieve the purpose of flipping and closing the shell cover of the feeding table. Then, through the cooperation of the arc plate and the linkage component, the purpose of flipping and switching between the feeding table and the shell cover can be achieved to meet the soldering requirements. After soldering, the feeding table is flipped downward in sequence to complete the reset, and at the same time, the rotating component and the toothed rod can be driven to realize the automatic flipping of the shell cover, so as to form a cyclic processing system and realize the continuous soldering operation of the circuit board.

One end of the connecting rod 1033 is fixedly connected with a toothed rod 1034. The two toothed rods 1034 are arranged vertically and alternately, and the tooth sections of the two toothed rods 1034 are arranged in opposite directions. The heights of the two toothed rods 1034 are respectively set at different levels, so that the two toothed rods 1034 can drive the second gear 2042 from the upper and lower sides, thereby realizing the forward and reverse rotation of the second gear 2042, so as to facilitate the operation of opening and closing the shell cover 2051. An arc-shaped plate 104 is also fixedly connected above the base 102; The feeding mechanism 200 includes a feeding component 201. The feeding component 201 includes a motor 2011. The motor 2011 is installed in the middle of the base 102. The output shaft of the motor 2011 is fixedly connected with a turntable 2012.

The feeding component 201 is assembled on the base 102. A plurality of linkage components 202 are arranged through the feeding component 201. The linkage component 202 includes a sliding sleeve 2021. The sliding sleeve 2021 is fixedly installed on the turntable 2012. A sliding rod 2024 is slidably connected in the sliding sleeve 2021. The bottom end of the sliding rod 2024 is fixedly connected with a roller 2023. One of the rollers 2023 contacts the arc-shaped plate 104. The roller 2023 can reduce the frictional resistance between it and the arc-shaped plate 104 and maintain the smooth movement of the roller 2023. And the roller 2023 can be pushed by the arc-shaped plate 104 to move the sliding rod 2024 upward, so that the toothed plate 2025 can move smoothly to achieve the purpose of transmission with the first gear 2031, so that the rotating shaft 2033 drives the material placing table 2034 and the shell cover 2051 to flip and exchange positions, making the material placing table 2034 face upward.

The top end of the sliding rod 2024 is fixedly connected with a toothed plate 2025. The movement track of the linkage component 202 follows the feeding component 201 and corresponds to the arc-shaped plate 104. Above the linkage component 202, there is a flipable feeding component 203. The flipable feeding component 203 includes a material placing table 2034. A material taking opening 2035 is arranged on one side of the material placing table 2034.

At the same time, the stable connection between the electronic component and the circuit board can be maintained. After the circuit board is automatically flipped, it is convenient for the subsequent welding device 101 to perform welding operations. At the same time, after welding, the linkage assembly 202 disengages from the arc-shaped plate 104, and the positions of the feeding table 2034 and the housing cover 2051 can be switched again to complete the reset. At the same time, when the transmission assembly 103 is in transmission with the rack 1034 again, the housing cover 2051 automatically flips open, thus facilitating material taking.,

In this way, it can be checked whether there is a problem with the installation of the electronic component or a problem of missing placement, so as to achieve the purpose of automatic detection. When the magnet 2057 corresponds to the disk 2073, the magnetic repulsion between the magnet 2057 and the disk 2073 can drive the movable rod 2075 to press the second switch 2078, so that the alarm 2076 stops alarming. In this way, it can be known that the electronic component is installed in place.

One side of the hydraulic control component 205 is provided with an alarm component 207.

[0027] In this embodiment: By providing a plurality of pressing components 206, each pressing piece 2061 can correspond to electronic components at different positions. When the pressing piece 2061 contacts the electronic components, the first piston 2063 can be smoothly pressed through the support rod 2062. Then, through hydraulic pressure, the second piston 2056 can drive the magnet 2057 to correspond to the disk 2073, and the repulsive force between the magnetic forces of the two can be used to achieve the purpose of pressing the second switch 2078 by the movable rod 2075, thereby detecting whether the electronic components are properly installed.

After welding, the feeding table 2034 is flipped downward in sequence to complete the reset, and at the same time, the rotating component 204 and the toothed rod 1034 can be driven to realize the automatic flipping of the shell cover 2051, thereby forming a cyclic processing system to realize the continuous welding operation of the circuit board.

[0028] A method for using a PCB circuit board production and welding device includes the following steps: S1. When welding the circuit board, place the circuit board and the electronic components aligned with the circuit board on the feeding table 2034 from the left side, and then control the motor 2011 to drive the turntable 2012 to rotate. The turntable 2012 drives the flipable feeding component 203 to rotate. When the second gear 2042 is engaged with the toothed rod 1034, the second gear 2042 drives the connecting shaft 2041 to rotate. The connecting shaft 2041 drives the rotating part 2044 to rotate. The rotating part 2044 presses the convex ball 2045 out of the fixing port 2043 and compresses the first spring 2046. At the same time, the rotating part 2044 drives the shell cover 2051 to flip, so that the liquid in the shell cover 2051 is pressed into the side shell 2055. Through hydraulic pressure, the second piston 2056 and the magnet 2057 are driven to move. When the magnet 2057 corresponds to the disk 2073, the magnetic repulsive force between the magnet 2057 and the disk 2073 drives the movable rod 2075 to move, and at the same time compresses the third spring 2074, so that the movable rod 2075 presses the second switch 2078. At the same time, the first switch 208 is pressed by the feeding table 2034. At this time, the alarm 2076 closes the alarm. When the magnet 2057 does not correspond to the disk 2073, at this time, the first switch 208 is pressed by the feeding table 2034, causing the alarm 2076 to alarm. After the shell cover 2051 is closed, the first spring 2046 drives the convex ball 2045 to reset and snap into the fixing port 2043 to limit the rotating part 2044. S2. Then continue to rotate the position of the feeding table 2034. When the roller 2023 enters the arc surface of the arc-shaped plate 104, the arc-shaped plate 104 squeezes the roller 2023 to drive the slide bar 2024 to move upward, causing the roller 2023 to compress the fourth spring 2022. And the slide bar 2024 drives the toothed plate 2025 to be in transmission with the first gear 2031. The first gear 2031 drives the rotating shaft 2033 and the feeding table 2034 to rotate, so that the positions of the shell cover 2051 and the feeding table 2034 are flipped and switched. After flipping, the welding surface of the circuit board is presented. When the circuit board is located at the position of the welding device 101, at this time, the welding device 101 performs welding operations on the circuit board and electronic components. S3. After welding, make the circuit board continue to move in a circular motion, so that the roller 2023 disengages from the arc-shaped plate 104. The fourth spring 2022 drives the slide bar 2024 to reset downward, causing the toothed plate 2025 to be in transmission with the first gear 2031, and then the feeding table 2034 and the shell cover 2051 complete the flipping and resetting. When the second gear 2042 passes another toothed rod 1034, the connecting shaft 2041 drives the shell cover 2051 to flip and open through the rotating part 2044. At this time, the second spring 2064 drives the first piston 2063 to reset upward, and the pressing piece 2061 is reset. The second piston 2056 is hydraulically reset, the magnet 2057 is separated from the magnetic disk 2073, and the third spring 2074 drives the magnetic disk 2073 and the movable rod 2075 to reset.
