Technical Field
[0001] This utility model belongs to the field of surface mount soldering technology, specifically relating to a surface mount soldering device for PCBA boards. Background Technology
[0002] PCBA stands for Printed Circuit Board Assembly. It refers to the process of mounting and connecting components onto a printed circuit board to form a complete circuit system. The assembly process of PCBA includes steps such as component installation, soldering, testing, calibration, and cleaning. It is a complex process. After various components are connected to the PCB board through the surface mount technology, a PCBA board is formed.
[0003] Existing soldering equipment typically uses manual adjustment to adjust the tilt angle of PCBA boards. The angle adjustment process lacks intuitive visual indicators, and operators cannot observe the specific value of the current tilt angle in real time. They need to use external measuring tools (such as protractors) for secondary measurement and confirmation, which not only increases the operation steps and time costs, but may also lead to soldering position deviations due to measurement errors. Therefore, a PCBA board surface mount soldering device is needed to help solve this problem. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0017] This specific embodiment is a PCBA board surface mount soldering device, such as... Figure 1-4As shown, the PCBA board surface mount soldering device includes a mounting base 1. A fixing ear 2 protrudes from the outer edge of the mounting base 1, and a mounting hole is vertically drilled through the fixing ear 2. The fixing ear 2 allows the mounting base 1 to be easily fixed in the corresponding position during operation. A mounting post 3 is installed at the top of the mounting base 1, and an embedding post 4 is rotatably embedded at the top of the mounting post 3. A positioning bolt 5 is installed on the side of the mounting post 3 near the top. The mounting post 3 and the positioning bolt 5 are threaded together. One end of the positioning bolt 5 presses against the side of the embedding post 4. Through the cooperation between the positioning bolt 5 and the mounting post 3, the height of the embedding post 4 can be easily adjusted during operation to meet the soldering requirements of different heights.
[0018] A protruding seat 6 is fixed at the top of the aforementioned embedded column 4. A clamping seat 7 is slidably disposed on one side of the protruding seat 6. A clamping cavity is provided between the protruding seat 6 and the clamping seat 7. A fastening bolt 8 is rotatably embedded on the protruding seat 6. The fastening bolt 8 passes through the clamping seat 7. The clamping seat 7 and the fastening bolt 8 are threadedly engaged. A protruding plate 9 is rotatably embedded on the protruding seat 6 in the clamping cavity. A fastening assembly 12 is fixed at the top of the protruding plate 9.
[0019] By coordinating the fastening bolts 8 and the clamping seat 7, the protruding plate 9 can be effectively clamped during operation, ensuring that the PCBA board 17 can be adjusted to the specified angle for subsequent surface mount installation.
[0020] The pressure seat 7 has a pointer 11 protruding from the middle of its top, and a scale ring 10 is embedded on the outer side of the protruding plate 9. Angle scale lines are engraved on the scale ring 10.
[0021] By coordinating the pointer 11 and the scale ring 10, the overall tilt angle of the protruding plate 9 can be effectively determined during operation, thereby facilitating the effective determination of the tilt angle of the PCBA board 17 during the adjustment process. This avoids subsequent secondary measurements, assists operators in quickly adjusting to the target soldering angle, and improves the accuracy of position adjustment.
[0022] Furthermore, a fastening assembly 12 is fixed at the top of the protruding plate 9. The fastening assembly 12 includes a sideways L-shaped fixing plate 13 fixed at the top of the protruding plate 9. A pressure plate 14 is installed at the top of the fixing plate 13. An adjustment cavity is provided on the fixing plate 13, and a lead screw 15 is rotatably installed in the adjustment cavity. In actual operation, the lead screw 15 can be lifted to clean it and ensure its normal use. At the same time, a corrugated protective tube can be sleeved on the outer edge of the lead screw 15 to protect it. A protrusion 142 is provided at the bottom of the clamping plate 14. A fastening cavity for clamping the PCB board 17 is provided between the fixing plate 13 and the clamping plate 14. A snap-fit strip 141 is provided on the cavity wall of the corresponding fastening cavity of the clamping plate 14 and the fixing plate 13. Two snap-fit strips 141 are arranged symmetrically at the top and bottom. A screw rod 15 is installed on the protrusion 142. The protrusion 142 and the screw rod 15 are threaded together. A rotating rod 16 is fixed to one end of the screw rod 15 that extends out of the fixing plate 13.
[0023] The fastening assembly 12, in which the fastening cavity formed by the fixing plate 13 and the pressing plate 14 is connected by the screw 15 and the protrusion 142, drives the pressing plate 14 to move along the vertical path defined by the limiting groove 131, thereby achieving uniform pressing of the PCB board 17. The symmetrically arranged snap-fit strips 141 are embedded in the edge of the PCB board 17 to enhance the clamping stability and prevent the board from sliding or shifting during the welding process.
[0024] Furthermore, a limit strip 143 is symmetrically protruding at the bottom of the clamping plate 14, and a limit groove 131 is symmetrically opened at the top of the fixing plate 13, with the limit strip 143 slidably disposed in the limit groove 131.
[0025] By cooperating with the limiting groove 131 and the limiting strip 143, the pressing plate 14 can slide along the fixed plate 13 during the adjustment process, ensuring that the pressing plate 14 will not be misaligned during the adjustment process.
[0026] Working principle: Efficient welding operations are achieved through a multi-directional adjustment and precise positioning mechanism. The mounting base 1 serves as a basic support and is fixed to the workbench through the fixing ears 2 on the outer edge and the mounting holes to ensure the overall stability of the device. The embedded column 4 at the top of the mounting column 3 can rotate around the axis. After rotating to the target angle, the angle is locked by tightening the side of the embedded column 4 with the positioning bolt 5, which can adapt to different welding angle requirements.
[0027] The protruding seat 6 and the clamping seat 7 form a clamping cavity. The fastening bolt 8 is threadedly engaged with the clamping seat 7, thereby assisting in clamping the protruding plate 9 and adjusting the overall tilt of the fastening assembly 12. The protruding plate 9 can rotate around the protruding seat 6. The scale ring 10 on its top cooperates with the pointer 11 on the top of the clamping seat 7 to achieve precise angle adjustment and ensure the soldering angle of the PCBA board 17.
[0028] After the PCB board 17 is placed into the fastening cavity, the rotating rod 16 drives the lead screw 15 to rotate in the adjustment cavity of the fixing plate 13. The protrusion 142 is threadedly engaged with the lead screw 15, which drives the clamping plate 14 to move vertically along the path defined by the limiting strip 143 and the limiting groove 131, and clamps the PCB board 17 together with the fixing plate 13. The upper and lower symmetrical snap-fit strips 141 are embedded in the edge grooves of the PCB board 17 to prevent the board from sliding during the soldering process.
[0029] All technical features in this embodiment can be freely combined according to actual needs.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
