[0002] A circuit board, generally referring to a printed circuit board, is a fundamental structure used in the electronics industry to support and connect electronic components. It is a thin board composed of insulating materials (such as fiberglass, paper-based phenolic resin, etc.) and one or more layers of copper foil. In the electronics manufacturing industry, especially in the processing and inspection of circuit boards (PCBs), accurate measurement of circuit board dimensions is one of the key steps to ensure product quality.
[0003] Traditional distance measurement methods often rely on manual measurement of circuit board dimensions using measuring tools. These methods are not only inefficient, but also difficult to guarantee measurement accuracy, especially when dealing with mass production, as they are prone to introducing human error. Utility Model Content
[0004] In order to overcome the shortcomings of traditional distance measurement methods, which often rely on manual measurement of circuit board dimensions using measuring tools, these methods are not only inefficient but also difficult to guarantee measurement accuracy. The purpose of this utility model is to provide a distance measurement device for circuit board processing.
[0005] The technical solution of this utility model is: a distance measuring device for circuit board processing, including a base, a support frame, a first measuring scale, a measuring slider, a measuring plate, a fixed pointer, a moving plate, a through groove, a rotating pointer, a second measuring scale, a fixed block, a bidirectional threaded rod, and a motor.

The first measuring scale is provided on the upper right side of the support frame, and two measuring sliders are symmetrically slidably connected to the right side of the support frame. A fixed pointer is connected to the top of each measuring slider, and a measuring plate is connected to the bottom of each measuring slider. A rectangular hole is opened in the middle of the top of the base. A movable plate is symmetrically slidably connected to the rectangular hole. A through groove is opened at the front end of each movable plate. A rotating pointer is rotatably connected to the lower part of each through groove. A second measuring scale is provided on the front side of the top of the base. Fixed blocks are symmetrically arranged on the left and right sides of the bottom of the base. A bidirectional threaded rod is rotatably connected to the two fixed blocks. The movable plate on the left side is threadedly connected to the threaded part on the left side of the bidirectional threaded rod, and the movable plate on the right side is threadedly connected to the threaded part on the right side of the bidirectional threaded rod. A motor is provided on the right side of the bottom of the base. The output shaft of the motor is connected to the bidirectional threaded rod.

Detailed Implementation
[0020] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.
[0021] A ranging device for circuit board processing, such as Figures 1-4 As shown, the circuit board includes a base 1, a support frame 3, a first measuring ruler 4, a measuring slider 5, a measuring plate 501, a fixed pointer 502, a moving plate 6, a through groove 601, a rotating pointer 7, a second measuring ruler 8, a fixing block 9, a bidirectional threaded rod 10, and a motor 11. A sliding groove 101 is provided on the rear side of the top of the base 1, and the support frame 3 is slidably connected within the sliding groove 101. The upper part of the support frame 3 is an L-shaped plate, and the lower part is a rectangular plate. The first measuring ruler 4 is provided on the upper right end of the support frame 3. The support frame 3 can drive the first measuring ruler 4 to move left and right on the top of the base 1. The first measuring ruler 4 is used to measure the distance between the front and rear sides of the circuit board. The right end of the support frame 3 is provided with a front... Two measuring sliders 5 are symmetrically slidably connected at the rear. A fixed pointer 502 is connected to the top of each measuring slider 5, indicating the reading on the first measuring scale 4. A measuring plate 501 is connected to the bottom of each measuring slider 5. The two measuring plates 501 contact the circuit board, and the reading indicated by the fixed pointer 502 is read to obtain the distance between the front and rear sides of the circuit board. A rectangular hole 102 is opened in the center of the top of the base 1. A movable plate 6 is symmetrically slidably connected to the rectangular hole 102. A through groove 601 is opened at the front end of each movable plate 6. A rotating pointer 7 is rotatably connected to the lower part of each through groove 601. When the rotating pointer 7 is not in use, it can be retracted (see reference). Figure 4The rotating pointer 7 has an inclined surface 701 at the upper part of the end near the through slot 601. The inclined surface 701 gradually moves away from the through slot 601 from the end of the rotating pointer 7 until the top of the rotating pointer 7. The inclined surface at the top of the rotating pointer 7 allows people to quickly unfold the rotating pointer 7. A second measuring ruler 8 is provided on the front side of the top of the base 1. When the rotating pointer 7 is unfolded, the front end of the rotating pointer 7 touches the top of the base 1, and the rotating pointer 7 indicates the reading on the second measuring ruler 8. The second measuring ruler 8 is used to measure the distance between the left and right sides of the circuit board. Fixed blocks 9 are symmetrically arranged on the left and right sides of the bottom of the base 1. Two bidirectional threaded rods 10 are rotatably connected to the two fixed blocks 9. The moving plate 6 on the left side is threadedly connected to the threaded part on the left side of the bidirectional threaded rod 10, and the moving plate 6 on the right side is threadedly connected to the threaded part on the right side of the bidirectional threaded rod 10. A motor 11 is provided on the right side of the bottom of the base 1. The output shaft of the motor 11 is connected to the bidirectional threaded rod 10. The motor 11 drives the bidirectional threaded rod 10 to rotate, thereby causing the moving plates 6 to move closer or further apart.
[0022] like Figure 1 As shown, a central axis 104 is provided at the top center of the base 1. The central axis 104 is used for positioning. When the circuit board is placed on the base 1, it can be placed according to the central axis 104. When the distance between the front and rear sides of the circuit board is measured using the second measuring ruler 8, the moving support frame 3 is moved closer to the central axis 104.
[0023] like Figure 2 As shown, it also includes bolts 302. The support frame 3 is provided with screw holes 301. The screw holes 301 are located on the rectangular plate. The screw holes 301 are internally threaded with bolts 302. The bottom end of the bolts 302 abuts against the slide groove 101. When the bolts 302 are loosened (i.e., the bolts 302 no longer abut against the slide groove 101), the support frame 3 can move left and right along the slide groove 101.
[0024] like Figure 3 As shown, it also includes a rubber plate 12. Both movable plates 6 are provided with a rubber plate 12 at their respective ends that are close to each other. When the rubber plate 12 comes into contact with the circuit board, the rubber plate 12 protects the surface of the circuit board from scratches.
[0025] like Figure 1 As shown, it also includes a door panel 13, a handle 14, and a sponge broom 15. A storage slot 103 is opened on the front of the top of the base 1. The storage slot 103 is used to store repair tools, such as screwdrivers. The door panel 13 is hinged above the storage slot 103 at the top of the base 1. The top of the door panel 13 is equipped with a handle 14. The sponge broom 15 is placed in the storage slot 103. Pull the handle 14 to rotate and open the door panel 13, take out the sponge broom 15, and use the sponge broom 15 to clean the debris on the circuit board and the workbench (debris will be generated during the circuit board processing and the debris will stick to the circuit board) to keep the working environment clean.
[0026] The circuit board is placed at the top center of the base 1. The rotating pointer 7 is rotated until its front end touches the top of the base (at this time, the rotating pointer 7 indicates the reading on the second measuring scale 8). The motor 11 is started, and the motor 11 drives the bidirectional threaded rod 10 to rotate. Since the two moving plates 6 are respectively connected to the threaded portions on the left and right sides of the bidirectional threaded rod 10, when the motor 11 rotates, the moving plates 6 on the left and right sides will move closer or further apart. When both rubber plates 12 on both sides touch the circuit board, the motor 11 is turned off, and the left and right readings are taken. The rotating pointers 7 on both sides indicate the readings on the second measuring scale 8. Subtracting the second reading from the first reading gives the distance between the left and right sides of the circuit board. Move the support frame 3 to the central axis 104 and move the two measuring sliders 5 so that the two measuring plates 501 are close to each other and touch the circuit board. Read the readings indicated by the two fixed pointers 502 (these readings are located on the first measuring scale 4). Subtracting the second reading from the first reading gives the distance between the front and rear sides of the circuit board. Compare the measured data with the data required for circuit board production to determine whether the circuit board is qualified.
[0027] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made using the content of this utility model specification, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
