[0008] Furthermore, L-shaped plates are respectively provided in the middle of the two opposing sides of the second conveying tracks. The openings of the L-shaped plates face downwards, the support plate can pass under the L-shaped plates, and the limiting post can pass through the inside of the L-shaped plates.

[0014] In summary, the technical solution of this utility model has the following beneficial effects: The structure of this utility model is reasonable. (1) It includes a frame, on which two conveyor tracks are provided with a length extending from left to right. The two conveyor tracks are distributed along the front and back. The two conveyor tracks can cooperate to transport the PCBA board in the left and right direction. The frame is also provided with a conveyor belt with a length extending from left to right. The conveyor belt is located above one of the conveyor tracks. The conveyor belt can drive the DC line to be transported in the left and right direction. Thus, when it is necessary to perform tin spraying on a set of PCBA boards and DC lines, the DC line is first inserted into the PCBA board, and then the PCBA board is placed between the two conveyor tracks. At the same time, the DC line is placed on the conveyor belt. Then, the two conveyor tracks are responsible for driving the PCBA board to the right (here, the example is that the assembly line works from left to right). At the same time, the conveyor belt is responsible for driving the DC line to the right, thereby realizing the synchronous movement of the PCBA board and the DC line. The connection point between the DC line and the PCBA board remains stable. (2) A wave soldering device is installed below the two conveyor tracks, and a positioning cylinder is installed above the two conveyor tracks. The positioning cylinder is equipped with a positioning rod. The positioning cylinder can drive the positioning rod to move up and down. The positioning rod can be positioned and engaged with the PCBA board downwards so that the PCBA board can stay above the wave soldering device. Thus, when the PCBA board and DC line are conveyed to the right above the wave soldering device, the positioning cylinder drives the positioning rod to move downwards to achieve the positioning engagement between the positioning rod and the PCBA board. Then the two conveyor tracks and the conveyor belt stop so that the PCBA board stays above the wave soldering device. (3) The wave soldering equipment can move up and down. The wave soldering equipment is equipped with a nozzle that can spray tin onto the connection point between the PCBA board and the DC line. When the PCBA board is above the wave soldering equipment, the wave soldering equipment will move upward. Then, the nozzle on the wave soldering equipment will spray tin onto the connection point between the PCBA board and the DC line. After the tin spraying is completed, the wave soldering equipment will reset downward. The positioning cylinder will drive the positioning rod to reset upward. Then, the two conveyor tracks and the conveyor belt will continue to transport the PCBA board and the DC line to the right. Then, it will be the turn of the next set of PCBA boards and DC lines to be tin-sprayed and soldered. This process is repeated. From this analysis, it can be seen that this utility model achieves stable transportation of PCBA boards and DC lines through the conveyor tracks and conveyor belts, and achieves precise tin spraying and soldering of PCBA boards and DC lines through the positioning rod and the wave soldering equipment. Thus, the welding quality of PCBA boards and DC lines is stabilized through automation. Attached Figure Description

[0018] See Figures 1 to 5This embodiment provides a bottom soldering production line, including a frame 1. The frame 1 is provided with two conveyor tracks 2 extending horizontally, distributed front to back, which can cooperate to transport PCBA boards in the left and right directions. The frame 1 is also provided with a conveyor belt 3 extending horizontally, located above one of the conveyor tracks 2, which can drive the DC line to be transported in the left and right directions. A wave soldering device 4 is provided below the two conveyor tracks 2, and a positioning cylinder 5 is provided above the two conveyor tracks 2. The positioning cylinder 5 is provided with a positioning rod 501, which can drive the positioning rod 501 to move up and down. The positioning rod 501 can be positioned downward to cooperate with the PCBA board so that the PCBA board can be stopped above the wave soldering device 4. The wave soldering device 4 can move up and down and is provided with a nozzle 401, which can spray solder upward to the connection point between the PCBA board and the DC line. Function: (1) The machine includes a frame with two conveyor tracks extending from left to right. The two conveyor tracks are distributed front to back and can cooperate to transport the PCBA board in the left and right direction. The frame is also equipped with a conveyor belt extending from left to right. The conveyor belt is located above one of the conveyor tracks and can drive the DC line to be transported in the left and right direction. So when it is necessary to perform soldering on a set of PCBA boards and DC lines, the DC line is first inserted into the PCBA board, then the PCBA board is placed between the two conveyor tracks, and the DC line is placed on the conveyor belt. Then the two conveyor tracks are responsible for driving the PCBA board to the right (here, the assembly line works from left to right). At the same time, the conveyor belt is responsible for driving the DC line to the right, thereby realizing the synchronous movement of the PCBA board and the DC line. The connection point between the DC line and the PCBA board remains stable. (2) A wave soldering device is installed below the two conveyor tracks, and a positioning cylinder is installed above the two conveyor tracks. The positioning cylinder is equipped with a positioning rod. The positioning cylinder can drive the positioning rod to move up and down. The positioning rod can be positioned and engaged with the PCBA board downwards so that the PCBA board can stay above the wave soldering device. Thus, when the PCBA board and DC line are conveyed to the right above the wave soldering device, the positioning cylinder drives the positioning rod to move downwards to achieve the positioning engagement between the positioning rod and the PCBA board. Then the two conveyor tracks and the conveyor belt stop so that the PCBA board stays above the wave soldering device.(3) The wave soldering equipment can move up and down. The wave soldering equipment is equipped with a nozzle that can spray tin onto the connection point between the PCBA board and the DC line. When the PCBA board is above the wave soldering equipment, the wave soldering equipment will move upward. Then, the nozzle on the wave soldering equipment will spray tin onto the connection point between the PCBA board and the DC line. After the tin spraying is completed, the wave soldering equipment will reset downward. The positioning cylinder will drive the positioning rod to reset upward. Then, the two conveyor tracks and the conveyor belt will continue to transport the PCBA board and the DC line to the right. Then, it will be the turn of the next set of PCBA boards and DC lines to be tin-sprayed and soldered. This process is repeated. From this analysis, it can be seen that this utility model achieves stable transportation of PCBA boards and DC lines through the conveyor tracks and conveyor belts, and achieves precise tin spraying and soldering of PCBA boards and DC lines through the positioning rod and the wave soldering equipment. Thus, the welding quality of PCBA boards and DC lines is stabilized through automation.

Preferably, the axial direction of the rotating sprockets at both ends of the first / third conveyor chain extends forward and backward, which better matches the second conveyor chain 204.
[0022] Specifically, each of the two second conveyor tracks 202 has an L-shaped plate 208 in the middle of its opposite side. The opening of the L-shaped plate 208 faces downward, allowing the support piece 206 to pass underneath it and the limiting post 207 to pass through the interior of the L-shaped plate 208. The L-shaped plates 208 on both the front and rear sides cooperate to limit the position of the PCBA board. Function: With the cooperation of the L-shaped plates 208 on both the front and rear sides, the front and rear edges of the PCBA board can be limited, thus facilitating soldering.
[0023] Specifically, the second frame 102 is also equipped with a protective cover 6, and the second conveyor track 202, wave soldering equipment 4, and positioning cylinder 5 are located inside the protective cover 6; the conveyor belt 3 includes a first conveyor belt 301 and a second conveyor belt 302 arranged sequentially from left to right.

Function: The material conveyor belt 7 can be used to place frequently used items by employees, providing better convenience.
[0026] Specifically, the positioning cylinder 5 is equipped with two sensors 9, which can monitor the position of the PCBA board downwards. One side of the conveyor track 2 can move back and forth relative to the frame 1, while the other side of the conveyor track 2 remains fixed relative to the frame 1. Function: The two sensors can accurately monitor the position of the PCBA board, facilitating positioning and soldering, and ensuring accurate start and stop of the conveyor track 2 and conveyor belt 3. The distance between the two conveyor tracks 2 is adjustable, making it suitable for PCBA boards of different widths.
[0027] Specifically, the wave soldering equipment 4 is equipped with several nozzles 401, which are evenly arranged. Function: In actual production, to better achieve batch soldering and improve efficiency, the large PCBA board typically includes several smaller PCBA boards, which are connected together by their edges. Before soldering is completed, the boards are not separated. Several DC lines are pre-inserted into each of the smaller PCBA boards to form a group. The large PCBA board is then placed between two conveyor tracks, and the DC lines are placed on the conveyor belt. When the large PCBA board is above the wave soldering equipment, the equipment moves upward, and the nozzles spray solder onto the connection points between the smaller PCBA boards and the DC lines. The two conveyor tracks and the conveyor belt continue to transport the large PCBA board and DC lines to the next process, where the large PCBA board is divided into several smaller PCBA boards, each of which is soldered to a DC line.
