Description

Technical Field

[0001] This utility model relates to the field of component soldering, and in particular to an automated soldering machine. Background Technology

[0002] In the existing filter product manufacturing process, in order to meet the requirements of integration and protection, the core components of the filter and its auxiliary electronic components are usually installed together in the housing. After the cover plate is placed at the opening of the housing, the sealing between the housing and the cover plate is achieved through a tin sealing process to ensure the electromagnetic shielding performance and environmental sealing of the product. Currently, the tin-sealing process mainly relies on operators holding high-temperature soldering guns to manually melt the tin and fill it into the joint between the cover plate and the shell. However, the high-temperature melting process of tin produces a large amount of harmful fumes and gases containing lead, tin and other flux components. Even if operators wear protective equipment, they may still inhale these fumes for a long time, causing potential health damage to the respiratory and nervous systems. Secondly, the quality and speed of manual soldering depend entirely on the operator's skill and concentration. The poor soldering consistency and low efficiency make it difficult to meet the requirements of large-scale production for cycle time and yield, becoming a bottleneck for improving production capacity and product quality.

[0015] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings: Please refer to Figure 1 and Figure 2 .

[0016] This utility model discloses an automated solder sealing machine, including a worktable 1; The workbench 1 is provided with a loading and unloading area, a spraying area, a processing area and a heat dissipation area in sequence, with the heat dissipation area located between the loading and unloading area and the processing area.

[0017] The worktable 1 is equipped with a turntable mechanism 2, which includes a drive motor, a gearbox and a disk body 21. In this embodiment, the drive motor is preferably a servo motor, so that the drive motor can drive the disk body 21 to rotate at a certain angle with high precision through the gearbox. Furthermore, the drive motor and gearbox are both fixedly connected to the interior of the worktable 1, the output shaft of the drive motor is fixedly connected to the input shaft of the gearbox, and the output shaft of the gearbox passes through the worktable 1 and is fixedly connected to the center of the disc 21. Furthermore, the turntable mechanism 2 is provided with multiple fixtures 22, which are fixedly connected to the top of the disc body 21. The multiple fixtures 22 are arranged around the center point of the disc body 21, and the fixtures 22 are close to the edge of the disc body 21. In this embodiment, it is preferable that there are four fixtures 22 on the disc body 21, with the center point of the disc body 21 as the center, and the interval between two adjacent fixtures 22 is 90°. The loading and unloading area, the spraying area, the processing area and the heat dissipation area surround the outer side of the disc body 21. The drive motor drives the disc 21 to rotate intermittently at equal angles via the gearbox. The disc 21 rotates 90° at a time, so that each fixture 22 passes through the loading / unloading area, the spraying area, the processing area and the heat dissipation area in sequence. When the disc 21 stops rotating, the four fixtures 22 are respectively located in the loading / unloading area, the spraying area, the processing area and the heat dissipation area.

[0018] A limiting groove 221 is provided on the fixture 22. The limiting groove 221 is located on the top of the fixture 22, which facilitates the insertion, application of solder paste, heating of solder paste and removal of the filter assembly 9. Furthermore, the workbench 1 is equipped with a loading and unloading mechanism located in the loading and unloading area. The loading and unloading mechanism is used to pick up and place the filter assembly 9 relative to the fixture 22. In this embodiment, the loading and unloading mechanism is preferably a robotic arm. The robotic arm clamps the filter assembly 9 to be soldered and places it into the limiting groove 221 of the fixture 22 located in the loading and unloading area, or removes the filter assembly 9 that has been soldered from the fixture 22 located in the loading and unloading area.

[0019] The filter assembly 9 includes a housing 91, a filter, electronic components, and a cover plate 92. The filter and electronic components are installed inside the housing 91, and the cover plate 92 is placed over the opening of the housing 91. After the above installation steps are completed in the previous process, the loading and unloading mechanism clamps the installed filter assembly 9 and places it in the limiting groove 221 of the fixture 22.

[0020] Please refer to Figures 1-3 .

[0021] The worktable 1 is equipped with a three-dimensional moving mechanism, which includes an X-axis lead screw device 31, a Y-axis lead screw device 32 and a Z-axis lead screw device 33; the X-axis lead screw device 31 is fixedly connected to the worktable 1, and an X-axis sliding plate is slidably connected to the X-axis lead screw device 31. Furthermore, the Y-axis lead screw device 32 is fixedly connected to the X-axis sliding plate, and the Y-axis lead screw device 32 is slidably connected to the X-axis lead screw device 31 through the X-axis sliding plate. The X-axis lead screw device 31 drives the Y-axis lead screw device 32 to reciprocate along the X-axis, thereby adjusting the X-axis position of the Y-axis lead screw device 32; the Y-axis sliding plate is slidably connected to the Y-axis lead screw device 32. Furthermore, the Z-axis lead screw device 33 is fixedly connected to the Y-axis slide plate, and the Z-axis lead screw device 33 is slidably connected to the Y-axis lead screw device 32 through the Y-axis slide plate. The Y-axis lead screw device 32 drives the Z-axis lead screw device 33 to reciprocate along the Y-axis, thereby adjusting the Y-axis position of the Z-axis lead screw device 33. A mounting bracket 331 is slidably connected to the Z-axis lead screw device 33. Furthermore, the three-dimensional moving mechanism is equipped with a spraying mechanism 4, which is located in the spraying area. The spraying mechanism 4 includes a spray gun 41, which is connected to the feeding device through a material tube. The feeding device sprays solder paste onto the surface of the filter assembly 9 through the spray gun 41. The spraying mechanism 4 is slidably connected to the Z-axis lead screw device 33. Furthermore, the spray gun 41 is fixedly connected to the mounting bracket 331, and the spray gun 41 is slidably connected to the Z-axis lead screw device 33 through the mounting bracket 331. The Z-axis lead screw device 33 drives the spray gun 41 to reciprocate along the Z-axis, thereby adjusting the Z-axis position of the spray gun 41. The X-axis lead screw device 31, the Y-axis lead screw device 32 and the Z-axis lead screw device 33 work together to drive the spray gun 41 to achieve three-dimensional movement in the spraying area, thereby accurately spraying solder paste onto the surface of the filter assembly 9. During the spraying process, the three-dimensional moving mechanism drives the spray gun 41 to move around the outer contour of the cover plate 92 for one revolution, and the solder paste can be evenly applied to the joint between the cover plate 92 and the housing 91 to complete the spraying.

[0022] Please refer to Figure 1 and Figure 4 .

[0023] A heating mechanism 5 is provided on the workbench 1. The heating mechanism 5 is located in the processing area and includes a heating coil 51. The filter assembly 9 located in the processing area is located below the heating coil 51, and the outline of the heating coil 51 matches the outer outline of the cover plate 92. It can accurately heat the solder paste on the gap between the cover plate 92 and the housing 91, melt it, and achieve a reliable connection. Furthermore, a connecting bracket is fixedly connected to the heating coil 51, and the connecting bracket is fixedly connected to the worktable 1. The connecting bracket is used to suspend the heating coil 51 in the processing area; the wire that supplies power to the heating coil 51 is fixed on the bracket to prevent the wire from affecting the operation of other components such as the disc 21.

[0024] The workbench 1 is equipped with a limiting mechanism 6 located in the processing area. The limiting mechanism 6 includes a drive cylinder 61. The drive cylinder 61 is fixedly connected to the workbench 1. A connecting rod 62 is slidably connected to the limiting mechanism 6. The output shaft of the drive cylinder 61 is fixedly connected to the connecting rod 62. A pressure block 621 is fixedly connected to the connecting rod 62. The pressure block 621 is located above the heating coil 51. Because some filters or electronic components inside the housing 91 may not be installed properly, the cover plate 92 may bulge slightly, increasing the gap between the housing 91 and the cover plate 92. After the solder paste melts, it flows into the housing 91. The output shaft of the drive cylinder 61 drives the pressure block 621 to press down the cover plate 92 of the filter assembly 9 via the connecting rod 62, thus pressing the cover plate 92 firmly and avoiding the above-mentioned problems. The heating coil 51 is wrapped around the outside of the pressure block 621 to prevent the pressure block 621 from squeezing the heating coil 51.

[0025] The workbench 1 is equipped with a first suction mechanism 7 and a second suction mechanism 8. The first suction mechanism 7 and the second suction mechanism 8 are located in the processing area and the heat dissipation area, respectively. The suction port of the first suction mechanism 7 is located above the heating coil 51, and the suction port of the second suction mechanism 8 is located above the fixture 22 in the heat dissipation area. Furthermore, in this embodiment, it is preferred that both the first suction mechanism 7 and the second suction mechanism 8 are air pumps, and the suction volume of the first suction mechanism 7 is less than that of the second suction mechanism 8. The first exhaust mechanism 7 only needs to extract the harmful gases produced by the heating coil 51 melting solder paste. If the wind speed is too high, it will easily interfere with the heating process. The first exhaust mechanism 7 only needs to operate at low power. The second air extraction mechanism 8 not only needs to remove harmful gases generated during solder paste curing, but also undertakes the function of accelerating curing. Therefore, it needs to operate at high power to accelerate the flow of hot air around the solder paste and extract it away, thereby accelerating the curing of the solder paste.

[0026] Please refer to Figures 1-4 .

[0027] When this device is in operation: The filter assembly 9 to be tinned is automatically placed into the fixture 22 by the loading and unloading mechanism. The turntable drives the four fixtures 22 to rotate intermittently in equal-angle increments, so that each fixture 22 passes through the spraying area, processing area and heat dissipation area in sequence, and finally returns to the loading and unloading area. When the fixture 22 carrying the filter assembly 9 enters the spraying area, the three-dimensional moving mechanism controls the spray gun 41 to move around the outer contour of the cover plate 92, and accurately sprays the solder paste onto the gap between the housing 91 and the cover plate 92. When the fixture 22 enters the processing area, the output shaft of the drive cylinder 61 pulls the pressure block 621 down to press the cover plate 92 through the connecting rod 62; at the same time, the heating coil 51 heats and melts the solder paste, and the first air extraction mechanism 7 removes the harmful gases generated during the melting of the solder paste; after the melting of the solder paste is completed, the heating coil 51 stops working, and the drive cylinder 61 drives the pressure block 621 to rise and reset. When the fixture 22 enters the heat dissipation area, the second air extraction mechanism 8 removes the harmful gases generated during the solder paste curing process and accelerates the curing of the solder paste. When the fixture 22 returns to the loading and unloading area, the loading and unloading mechanism removes the filter assembly 9 that has been soldered from the fixture 22 and replaces it with the next filter assembly 9 to be soldered. The four fixtures 22 cycle through the above process under the drive of the turntable to achieve continuous automated production.

[0028] This utility model provides an automated solder sealing machine. A loading and unloading mechanism automatically places the filter assembly to be soldered into a fixture. A turntable mechanism drives the fixture sequentially through the spraying area and the processing area, achieving continuous operation. In the spraying area, a three-dimensional moving mechanism precisely controls the spraying mechanism to uniformly spray solder paste onto the surface of the filter assembly. In the processing area, a heating mechanism heats and melts the solder paste to complete the encapsulation process. During this process, a first exhaust mechanism continuously extracts and removes harmful fumes and gases generated during heating, significantly reducing the concentration of pollutants in the working environment. Furthermore, the automated solder sealing operation reduces operator intervention and effectively avoids operator contact with harmful substances. In addition, the turntable mechanism is equipped with multiple fixtures to support the simultaneous operation of loading and unloading, spraying, and processing, enabling the loading and unloading mechanism, spraying mechanism, and heating mechanism to operate continuously, greatly reducing equipment waiting time, improving the overall efficiency and consistency of the tin sealing operation, and meeting the high-cycle requirements of large-scale production.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
