[0002] SMT (Surface Mount Technology) refers to a series of processes performed on a PCB (Printed Circuit Board). Due to the lack of positioning structures during the packaging process, existing SMT packaging devices are prone to misalignment. Therefore, it is necessary to add a positioning structure to the existing surface mount packaging devices.

[0003] The technical solution disclosed in Chinese Patent No. CN219536437U, through the setting of connecting rods, worm gears, turbines, gears, bent toothed plates, clamping plates and soft pads, has a positioning function during use, which can quickly lock and fix it in place, preventing it from shifting during processing. At the same time, it can be used for circuit boards of different sizes, and the adjustment is simple and convenient. The soft pads make the fixing effect better.

[0004] However, the device still has shortcomings: it lacks an automatic loading and unloading function, requiring a lot of manual intervention in the process, which leads to low efficiency in surface mount packaging. Utility Model Content

The body of motor A is connected to the operating table, and the output end of motor A is coaxially connected to the end of one of the drive shafts.

[0013] Preferably, a chute A is provided on the support platform in a direction perpendicular to the feeding direction of the conveyor belt, and two sliders are slidably arranged in the chute A, with clamps on both sides connected to the corresponding sliders.

[0014] Preferably, the drive component B includes a bidirectional module, which is disposed in the slide groove A and connected to the support platform. The two output ends of the bidirectional module are respectively connected to the sliders on the corresponding sides.

[0015] Preferably, a slide groove B is provided in the center between the slots on both sides of the support platform, and the slide is located inside the slide groove B and slidably connected to its inner wall.

[0019] On the other hand, this utility model also proposes an SMT surface mount packaging device with the above-mentioned positioning structure, which further includes a stand plate and a robotic arm.

[0020] Compared with the prior art, the present invention has the following beneficial technical effects:

[0021] By setting up a structure with a conveyor belt and a support platform, the conveyor belt enables automatic feeding of the base plate. By setting up two relatively sliding clamps, the base plate is centered on both sides and clamped and positioned. At the same time, by setting up a flip-adjustable baffle, the baffle blocks the conveying of the base plate. The baffle works in conjunction with the clamps on both sides to keep the base plate in the same processing position. After the baffle flips down, it can release the blockage of the base plate and resume conveying. Attached Figure Description

[0028] like Figures 1-4As shown, the positioning structure proposed in this utility model includes an operating table 1, a support platform 6, a clamping plate 8, a drive assembly B, a slide 12, and a drive assembly C. Two parallel conveyor belts 4 are installed on the operating table 1, and a drive assembly A is installed on the operating table 1 to drive the conveyor belts 4. The drive assembly A includes a drive shaft 2 and a motor A5. There are two drive shafts 2. A conveying trough is provided on the operating table 1, and the two parallel drive shafts 2 are both located within the conveying trough and rotatably connected to the operating table 1. Two drive rollers 3 are symmetrically arranged on each drive shaft 2 about the center of the conveying trough. The drive rollers 3 on the same side of the two drive shafts 2 are respectively connected by a conveyor belt 4. The body of the motor A5 is connected to the operating table 1, and the output end of the motor A5 is coaxially connected to the end of one of the drive shafts 2. The support platform 6 is connected to the operating platform 1. A slot 61 is provided on the support platform 6, and the conveyor belt 4 is located within the slot 61. The lower surface of the load-bearing end of the conveyor belt 4 is slidably connected to the bottom surface of the slot 61, and the upper surface of the load-bearing end of the conveyor belt 4 is flush with the upper surface of the support platform 6. A chute A62 is provided on the support platform 6 in a direction perpendicular to the feeding direction of the conveyor belt 4. Two sliders 7 are slidably arranged within the chute A62. Clamping plates 8 on both sides are connected to the corresponding sliders 7, and the bottom surface of the clamping plates 8 is slidably connected to the upper surface of the support platform 6. Pressure sensors A9 are provided on the sides of the two clamping plates 8 that are close to each other, and protective pads 10 are provided on the sides of the clamping plates 8 that are close to each other. The protective pads 10 cover the outside of the pressure sensors A9. The pressure sensors A9 are electrically connected to a controller, and the controller is electrically connected to a drive assembly B. The drive assembly B includes a bidirectional module 11, which is disposed within the slide groove A62 and connected to the support platform 6. The two output ends of the bidirectional module 11 are respectively connected to the corresponding sliders 7. In operation, the drive assembly B drives the two clamping plates 8 to move synchronously away from or towards each other in a direction perpendicular to the conveying direction of the conveyor belt 4. A slide groove B63 is centrally located between the two slots 61 on the support platform 6. A conductive slide rail 17 is disposed within the slide groove B63. A slide frame 12 is slidably connected to the conductive slide rail 17 and is located inside the slide groove B63, slidably connected to its inner wall. The slide frame 12 is rotatably connected to a blocking plate 14. A linear module 13, which drives the slide frame 12, is disposed within the slide groove B63. A pressure sensor B15 is disposed on the blocking plate 14 and is electrically connected to a controller, which is electrically connected to the drive assembly A. The drive assembly C includes a motor B16. The body of the motor B16 is connected to the support platform 6, and the output end of the motor B16 is connected to the baffle plate 14. When the drive assembly C is in operation, it drives the baffle plate 14 to rotate.

[0029] In this embodiment, the base carrier board for loading SMT components is placed on the conveyor belt 4, with both ends resting on the two side conveyor belts 4 respectively. The motor A5 is started, driving the drive shaft 2 and drive roller 3 to rotate, thereby driving the conveyor belt 4 to move. The conveyor belt 4 transports the carrier board to the support platform 6. When the front end of the carrier board contacts the pressure sensor B15, the motor A5 stops running, and the bidirectional module 11 drives the clamping plates 8 on both sides to move closer to each other. When the pressure sensors A9 on both sides collect the pressure parameter value within the set range, the bidirectional module 11 stops moving, and the carrier board position is fixed at this time. After the carrier board is processed, the motor B16 is started, driving the blocking plate 14 to rotate clockwise. The bidirectional module 11 drives the clamping plates 8 on both sides to move in the opposite direction, and the motor A5 is started again. After the current carrier board is transported away, the blocking plate 14 rotates upward and resets. The operator can pick up the processed carrier board at the output end of the conveyor belt 4 along the gap between the two side conveyor belts 4, while the next set of carrier boards is blocked and limited by the blocking plate 14 and the above subsequent steps are started.

The stand plate 18 is connected to the operating table 1. A reflector 19 is provided on the side of the stand plate 18 facing the support platform 6. A lamp housing 20 is provided at the top of the stand plate 18 and is rotatably connected to it. A lamp plate 21 is provided on the lamp housing 20, and a locking knob 22 is provided on the stand plate 18 to restrict the rotation of the lamp housing 20.

The robotic arm 24 is connected to the bracket 23 and drives the suction nozzle 25.

[0032] In this embodiment, during actual operation, some components with long pins or missing parts need to be patched, and light detection and auxiliary positioning are required. At this time, by rotating the lamp housing 20, the angle of the light from the lamp board 21 to the reflector 19 changes, thereby using the reflector 19 to adjust the angle of the light hitting the base plate, avoiding direct stimulation of the human eye by the light. Meanwhile, the robotic arm 24 drives the suction nozzle 25 to automatically grab the components.

[0033] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
