Description

Technical Field

[0001] This utility model relates to the field of PCB board processing technology, specifically to a PCB board soldering machine with rapid cooling. Background Technology

[0002] In the field of electronic product manufacturing technology, various processing equipment is required, among which PCB boards are the most common. PCB boards, also known as printed circuit boards, primarily serve to support and connect various electronic components; they are the carriers of these components and are therefore very important. During the assembly process of the PCB board and terminals, fixtures are used to fix the PCB board and terminals onto a soldering machine, which then solders the PCB board and terminals together.

[0003] For example, the utility model application with application number CN202322196731.5 relates to the field of soldering technology and discloses a PCB board soldering machine. Through the above technical solution, the PCB board is inspected in a timely manner after soldering, and unqualified boards are re-soldered to reduce the defect rate and thus reduce rework costs. However, the existing soldering machine does not dissipate heat quickly during soldering, and the cooling efficiency is slow, which leads to overheating of the PCB board surface and affects subsequent processes.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided a PCB board soldering machine with rapid cooling. Utility Model Content

[0005] The purpose of this invention is to provide a PCB soldering machine with rapid cooling to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a PCB board soldering machine for rapid cooling, comprising a processing table and a cooling component. The bottom of the processing table is provided with a base frame, and the cooling component for simultaneous cooling on both sides is provided at the upper end of the processing table. The cooling component includes a cooling platform, a cooling chamber, a water pipe, a fan, and a blower plate. The cooling platform is provided with a cooling chamber, and the cooling chamber is provided with a water pipe. The fan is connected to the rear side of the cooling platform through a pipe, and a blower plate is provided on the side of the cooling platform.

[0007] Furthermore, two sets of air blowers are symmetrically arranged about the vertical central axis of the cooling platform, and the air blowers and the cooling chamber are connected.

[0008] Furthermore, the outer side of the processing table is provided with a limiting component for limiting the circuit board, and the number of limiting components is set to four sets.

[0009] Furthermore, the limiting component includes a rotating rod and a limiting plate, and the limiting plate is provided at the top of the rotating rod.

[0010] Furthermore, the limiting assembly also includes a threaded rod and a pressure plate, wherein the end of the limiting plate is provided with a threaded rod, and the lower end of the threaded rod is connected to the pressure plate.

[0011] Furthermore, the base frame has a movable groove on its surface, and a movable frame is installed inside the movable groove. An electric push rod is installed on the rear side of the movable frame.

[0012] Furthermore, the surface of the movable frame is provided with an adjustment groove, and an adjustment block is provided inside the adjustment groove.

[0013] Furthermore, a power wheel is mounted on the rear side of the adjustment block via a motor, and an organic body is mounted on the front side of the adjustment block.

[0014] This invention provides a PCB soldering machine with rapid cooling, which has the following beneficial effects:

[0015] 1. This utility model connects a water tank inside the processing table through a water pipe, and the water flows in the water pipe under the action of a water pump to cool down the temperature in the cooling chamber, thereby lowering the temperature of the cooling table. The cooling table transfers heat and cools down the back of the circuit board being soldered. At the same time, the air in the cooling chamber after cooling is blown out from the blower plate by the fan, and the blower plate further cools down the circuit board on both sides, so that it can be cooled down quickly during soldering.

[0016] 2. This utility model uses a limiting plate to rotate and adjust the position at the top of the rotating rod. When the circuit board is soldered, the limiting plate rotates and is positioned above the cooling platform. The threaded rod rotates in the limiting plate to adjust the height of the pressure plate, so that the pressure plate presses down and limits the circuit board surface, preventing the circuit board from shifting during soldering. The electric push rod controls the movement of the moving frame in the moving slot through telescopic control, which is used for the forward and backward movement of the machine body. The power wheel is driven by the motor, which causes the adjusting block to drive the machine body to move horizontally in the adjusting slot. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figure 1 As shown, a rapid cooling PCB soldering machine includes a processing table 1 and a cooling component 3. A base frame 2 is provided at the bottom of the processing table 1, and a limiting component 4 for limiting the circuit board is provided on the outer side of the processing table 1. The number of limiting components 4 is four. The limiting component 4 includes a rotating rod 401 and a limiting plate 402. The limiting plate 402 is provided at the top of the rotating rod 401. The limiting plate 402 rotates and adjusts its position at the top of the rotating rod 401. When the circuit board is soldered, the limiting plate 402 rotates and is positioned above the cooling table 301. The limiting component 4 also includes a threaded rod 403 and a pressure plate 404. The threaded rod 403 is provided at the end of the limiting plate 402. The threaded rod 403 rotates in the limiting plate 402 to adjust the height position of the pressure plate 404, so that the pressure plate 404 presses down and limits the circuit board surface to prevent the circuit board from shifting during soldering. The lower end of the threaded rod 403 is connected to the pressure plate 404.

[0023] like Figure 2 As shown, a cooling assembly 3 for simultaneous cooling on both sides is disposed at the upper end of the processing table 1. The cooling assembly 3 includes a cooling table 301, a cooling chamber 302, a water pipe 303, a fan 304, and a blower plate 305. The cooling chamber 302 is disposed inside the cooling table 301, and the water pipe 303 is disposed inside the cooling chamber 302. The water pipe 303 is connected to a water tank inside the processing table 1, and the water flows in the water pipe 303 under the action of a water pump, cooling the temperature in the cooling chamber 302, thereby lowering the temperature of the cooling table 301. A fan 304 is connected to the rear side of the cooling platform 301 via a pipe. The cooling platform 301 performs heat transfer and cooling on the back of the soldering circuit board. At the same time, the air in the cooling chamber 302 after cooling is blown out from the blower plate 305 by the fan 304. The blower plate 305 is also provided on the side of the cooling platform 301. The blower plate 305 further cools the circuit board on both sides, so that it can be cooled down quickly during soldering. There are two sets of blower plates 305 symmetrically arranged about the vertical central axis of the cooling platform 301, and the blower plates 305 and the cooling chamber 302 are connected internally.

[0024] like Figure 3 As shown, the base frame 2 has a moving groove 5 on its surface, and a moving frame 6 is installed inside the moving groove 5. An electric push rod 7 is installed on the rear side of the moving frame 6. The electric push rod 7 controls the moving frame 6 to move in the moving groove 5 by telescopic control, which is used for the forward and backward movement of the body 11. The moving frame 6 has an adjustment groove 8 on its surface, and an adjustment block 9 is installed inside the adjustment groove 8. A power wheel 10 is installed on the rear side of the adjustment block 9 by a motor. The power wheel 10 is driven by the motor to make the adjustment block 9 move the body 11 horizontally in the adjustment groove 8. The body 11 is installed on the front side of the adjustment block 9.

[0025] In summary, this rapid cooling PCB soldering machine firstly... Figures 1-3 The structure shown involves placing the circuit board to be soldered on the cooling platform 301, rotating the limiting plate 402 to position it above the cooling platform 301, and rotating the threaded rod 403 to move the pressure plate 404 downwards. This pressure plate 404 presses down on the surface of the circuit board to prevent it from shifting during soldering. Then, the machine body 11 performs soldering on the circuit board. During soldering, the water pump connected to the water pipe 303 operates, and the water flowing inside the water pipe 303 cools the temperature in the cooling chamber 302, thereby lowering the temperature of the cooling platform 301. The heat exchanger 301 cools the back of the circuit board being soldered. Simultaneously, the air in the cooling chamber 302 is blown out from the blower plate 305 by the fan 304. The blower plate 305 further cools the circuit board on both sides, allowing it to cool down quickly during soldering. When the machine body 11 is moved, the electric push rod 7 is extended and retracted to control the moving frame 6 to move in the moving slot 5 for the forward and backward movement of the machine body 11. The power wheel 10 is driven by the motor, causing the adjusting block 9 to move the machine body 11 horizontally in the adjusting slot 8, ensuring the soldering of the circuit.
