[0002] SMT (Surface Mount Technology) is an abbreviation for a series of processes performed on a PCB (Printed Circuit Board). SMT is a surface mount technology, one of the most popular technologies and processes in the electronics assembly industry.

[0003] In existing technologies, circuit board assembly requires thickness inspection after production. However, traditional methods rely on manual, one-time inspections, which cannot be performed quickly in batches on an assembly line, resulting in stagnant processing efficiency and impacting production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a thickness detection device for circuit board mounting, which solves the problem that traditional methods rely on manual single-pass inspection, making it impossible to quickly inspect batches of circuit board mountings in an assembly line manner, thus failing to improve processing efficiency and affecting production efficiency.

[0005] To achieve the above objectives, a thickness detection device for circuit board surface mount is provided, comprising: a detection table, side plates fixedly connected to both ends of the rear side of the detection table, an electric telescopic rod fixedly connected to the top of the side plates, a laser rangefinder fixing plate fixedly connected to the extension end of the electric telescopic rod, a laser rangefinder fixedly connected to the bottom center of the laser rangefinder fixing plate, sliding grooves provided on both sides of the upper side of the detection table, a slider slidably fitted inside the sliding groove, a movable frame fixedly connected to the top of the slider, a fixed frame fixedly connected to the front side of the upper surface of the detection table, and a threaded rod rotatably connected inside the fixed frame.

[0013] The above-mentioned solution has the following beneficial effects:

[0014] 1. This utility model is provided with: a testing platform, a movable frame, a tension spring and a contact plate. By placing the circuit board patch structure on the upper surface of the testing platform, the bottom tension spring of the movable frame is elastically stretched to securely attach the inner side of the movable frame and the circuit board patch.

[0024] This section will describe in detail the specific embodiments of the present utility model. The preferred embodiments of the present utility model are shown in the accompanying drawings. The purpose of the drawings is to supplement the textual description with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the present utility model, but they should not be construed as limiting the scope of protection of the present utility model.

[0025] Reference Figure 1-4 This utility model discloses a thickness detection device for circuit board patch, comprising: a detection platform 1, side plates 2 fixedly connected to both ends of the rear side of the detection platform 1, an electric telescopic rod 4 fixedly connected to the top of the side plates 2, the electric telescopic rod 4 extending to lower a laser rangefinder fixing plate 5, and the thickness of the patch being measured by the laser rangefinder after lowering; the extended end of the electric telescopic rod 4 is fixedly connected to the laser rangefinder fixing plate 5, and a laser rangefinder is fixedly connected to the bottom center of the laser rangefinder fixing plate 5; sliding grooves 6 are provided on both sides of the upper part of the detection platform 1, and sliders 16 are slidably fitted inside the sliding grooves 6; a movable frame 3 is fixedly connected to the top of the sliders 16; by placing the circuit board patch structure on the upper surface of the detection platform 1, the movable frame 3 is elastically stretched by the bottom tension spring 17; a fixed frame 7 is fixedly connected to the front side of the upper surface of the detection platform 1, and a threaded rod 11 is rotatably connected inside the fixed frame 7.

[0026] Threaded blocks are threaded to one end and the middle of the threaded rod 11. A contact plate 12 is fixedly connected to the front side of the threaded block. The contact plate 12 will be moved. Since the front side of the moving frame 3 is abutted by the auxiliary roller 15, it can cooperate with the rotation of the auxiliary roller 15 during the movement to transport the circuit board structure. The inner side of the moving frame 3 is fastened to the circuit board patch. After the patch is fastened, the other side of the circuit board abuts against the contact plate 12, and it is held in a clamped state. Several auxiliary rollers 15 are rotatably connected inside the moving frame 3. A tension spring 17 is fixedly connected between the inner wall of the slide 6 and the slider 16. Detection platforms 9 are fixedly connected to both sides of the upper middle part of the detection table 1. Secondary detection platforms 9 are fixedly connected to both sides of the bottom end of the detection table 1. The telescopic rod 14 has a lifting plate 13 fixedly connected to its drive end. When the lifting plate 13 is lowered, the stop block 10 is retracted to the bottom of the detection table 1, and the circuit board can then move continuously for easy transport. Stop blocks 10 are fixedly connected to both sides of the upper part of the lifting plate 13. During the transport operation of the circuit board structure, after moving to one side of the stop block 10, the stop block 10 blocks the circuit board and keeps the thickness detection position accurate. The stop block 10 penetrates the interior of the detection table 1. A drive motor 8 is fixedly connected to one end of the fixed frame 7. Driven by the drive motor 8, the threaded rod 11 rotates and engages with the contact plate 12 to achieve threaded movement. The drive end of the drive motor 8 is fixedly connected to the threaded rod 11.

[0027] Working principle: In use, the circuit board patch structure is first placed on the upper surface of the testing table 1. The bottom tension spring 17 of the moving frame 3 elastically stretches the patch, securing it firmly to the inner side of the moving frame 3 and the circuit board patch. After bonding, the other side of the circuit board contacts the contact plate 12, maintaining a clamped state. This can be achieved by driving the drive motor 8, which rotates the threaded rod 11, engaging with the contact plate 12 via a threaded connection. This allows for threaded movement of the contact plate 12. Since the front of the moving frame 3 is contacted by auxiliary rollers 15, the movement... During the process, the auxiliary roller 15 can be rotated to transport the circuit board to the side of the stop 10. The stop 10 can block the thickness detection and keep the accurate position. At this time, the electric telescopic rod 4 can be extended to lower the laser rangefinder fixing plate 5. After the lowering, the thickness of the patch can be measured by the laser rangefinder. After the measurement is completed, the second telescopic rod 14 is retracted and the lifting plate 13 is lowered. At this time, the stop 10 is retracted to the bottom of the detection table 1. Then the circuit board can move continuously, which facilitates the transport operation.
