Description

Technical Field

[0001] This utility model relates to the field of frequency converter soldering technology, specifically to a frequency converter soldering device. Background Technology

[0002] A frequency converter is a power control device that uses frequency conversion technology and microelectronics technology to control an AC motor by changing the frequency of the motor's power supply.

[0003] A frequency converter mainly consists of a rectification unit, filter, inverter, braking unit, drive unit, detection unit, and microprocessor unit. The frequency converter adjusts the output voltage and frequency by switching its internal IGBTs, providing the required power voltage according to the actual needs of the motor, thereby achieving energy saving and speed regulation. In addition, the frequency converter has many protection functions, such as overcurrent, overvoltage, and overload protection. With the continuous improvement of industrial automation, frequency converters have been widely used. During the production process of frequency converters, the PCB board needs to be soldered onto the pins inside the frequency converter; currently, automatic soldering machines are commonly used for this.

[0004] However, existing automatic soldering machines have the following problems during soldering: the pins on the frequency converter are usually in the form of multiple pin groups arranged in a row. In order to solder multiple pins at the same time, the soldering iron of the soldering machine is usually selected with a flat end. However, since the pin arrangement direction on the frequency converter is usually multiple, the existing automatic soldering machine only drives the soldering iron to move during soldering. For pin groups with changing arrangement direction, it is not convenient to solder all the pins of the pin group at one time. Multiple translations are required to complete the soldering, resulting in a decrease in soldering efficiency. Utility Model Content

[0006] A frame and a mobile module are provided. The mobile module is mounted on the frame. The output end of the mobile module is equipped with a rotary cylinder. The output end of the rotary cylinder is equipped with a mounting bracket. The mounting bracket is equipped with a soldering iron. The mobile module is used to drive the soldering iron to move to align with the pin group. The rotary cylinder is used to drive the end of the soldering iron to rotate to correspond to the arrangement direction of the pin group.

[0007] A solder feeder, which is mounted on the frame, is used to feed solder to the soldering iron;

[0008] The conveying module has a carrier at its output end, which is used to place the frequency converter and PCB board. The conveying module is used to convey the frequency converter and PCB board to a position below the soldering iron.

[0024] To make the technical problem to be solved, the technical solution, and the beneficial effects of this utility model clearer, the present utility model will now be described in detail with reference to the accompanying drawings. This drawing is a simplified schematic diagram, illustrating only the basic aspects of the present utility model, and therefore only shows the components relevant to the present utility model. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0025] Please refer to Figure 1-5 This utility model provides a frequency converter soldering device 100, including a frame 10 and a moving module, a solder feeder and a conveying module 40. In this embodiment, the pins on the frequency converter 200 are usually in the form of two pin groups 202 arranged in a row.

[0026] A movable module is mounted on the frame 10. The output end of the movable module is equipped with a rotary cylinder 24, and the output end of the rotary cylinder 24 is equipped with a mounting bracket 25. A soldering iron 26 is mounted on the mounting bracket 25. The movable module drives the soldering iron 26 to move and align with the pin group 202. The rotary cylinder 24 drives the end of the soldering iron 26 to rotate so that it corresponds to the arrangement direction of the pin group 202. Specifically, in this embodiment, the end of the soldering iron 26 is flat and adapted to the length of the pin group 202. The specific structure of the soldering iron 26 is prior art and will not be described in detail in this embodiment.

[0027] Furthermore, the moving module includes a horizontal moving module 21, a mounting plate 22 disposed at the output end of the horizontal moving module 21, and a lifting moving module 23 disposed on the mounting plate 22. The output end of the lifting moving module 23 is fixedly connected to the rotary cylinder 24. Specifically, in this embodiment, both the horizontal moving module 21 and the lifting moving module 23 are screw drive structures. The horizontal moving module 21 is disposed along the width direction of the frame 10, and the lifting moving module 23 is disposed along the thickness direction of the frame 10.

[0028] A solder feeder is mounted on the frame 10 and is used to feed solder to the soldering iron 26. The solder feeder is not shown in the figure. Specifically, the solder feeder used in this embodiment is existing technology. Specifically, in this embodiment, the solder feeder model is BK373, purchased from Shenzhen Baiguang Electronics Technology Co., Ltd. The model of the solder feeder is not limited to this; any solder feeder capable of automatic solder feeding can be used in the technical solution of this application.

[0029] The mounting bracket 25 is equipped with a solder feeder 251 and a limiting rod 252. The solder feeder 251 has a wire-passing groove 2511, and the limiting rod 252 is located within the wire-passing groove 2511. The solder wire from the output end of the solder feeder passes through the wire-passing groove 2511, corresponding to the end of the soldering iron 26, and the solder wire is located between the limiting rod 252 and the wire-passing groove 2511. Furthermore, both the limiting rod 252 and the wire-passing groove 2511 are inclined to facilitate the end of the solder wire passing through the wire-passing groove 2511 and contacting the end of the soldering iron 26. The limiting rod 252 and the wire-passing groove 2511 can guide the solder wire, so that the solder feeder does not move with the soldering iron 26, reducing damage to the solder feeder. The mounting bracket 25 is equipped with a circular support plate 253, through which the soldering iron 26 passes, and the solder feeder 251 is fixedly connected to the support plate 253. During soldering, the end of the solder wire passes through the output end of the solder feeder, then through the wire guide 2511 and comes into contact with the end of the soldering iron 26 and is melted. The soldering iron 26 then solders the pin group 202 and the PCB board 300 through the molten solder.

[0030] The output end of the conveying module 40 is provided with a carrier 41, which is used to place the frequency converter 200 and the PCB board 300. The conveying module 40 is used to convey the frequency converter 200 and the PCB board 300 to a position below the soldering iron 26. Specifically, in this embodiment, the conveying module 40 is a lead screw drive mechanism, and the conveying module 40 is arranged along the length direction of the frame 10.

[0031] The carrier 41 is provided with a support block 411, and the support block 411 is provided with a cavity 412 adapted to the frequency converter 200. The carrier 41 is also provided with a telescopic cylinder 413, and the output end of the telescopic cylinder 413 is provided with a pressure block 414. The telescopic cylinder 413 is used to drive the pressure block 414 to press against the PCB board 300.

[0032] Furthermore, the pressure block 414 includes a main body 4141 and two pressing parts 4142, which are adapted to the mounting slot 201 on the frequency converter 200. Specifically, only a portion of the frequency converter 200 is shown in this embodiment. The mounting slot 201 is adapted to the PCB board 300, which has several circular holes corresponding to the pins. The two pressing parts 4142 are located in the middle of the PCB board 300.

[0033] The inverter soldering device 100 also includes a rinsing assembly, which includes a rinsing water tank 51, a rinsing nozzle 52, and a rinsing water reservoir 53. The rinsing nozzle 52 and the rinsing water reservoir 53 are connected. The rinsing nozzle 52 is positioned facing the rinsing water tank 51 and is used to rinse the soldering iron 26. After the soldering iron 26 has been soldered multiple times, the end of the soldering iron 26 is moved to the rinsing nozzle 52 by a moving module for rinsing, thereby preventing impurities deposited on the soldering iron 26 from affecting the soldering process.

[0034] Furthermore, the inverter soldering device 100 also includes a CCD industrial camera 60 mounted on the mounting plate 22, which is positioned facing the carrier 41 and is used to photograph the soldering process. After the soldering iron 26 finishes soldering, the horizontal movement module 21 controls the CCD industrial camera 60 to move and align with the inverter 200 on the carrier 41 to photograph the soldering process.

[0035] During soldering, a moving module drives the soldering iron 26 to align with the pin group 202, and a rotary cylinder 24 drives the end of the soldering iron 26 to rotate to correspond with the arrangement direction of the pin group 202. Compared to the prior art, which only drives the soldering iron 26 to translate during soldering, the technical solution adopted by this utility model enables the end of the soldering iron 26 to rotate to correspond with the arrangement direction of the pin group 202, which has a changing arrangement direction. This allows all pins of the pin group 202 to be soldered at once, improving soldering efficiency.
