Detailed Implementation

[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] Referring to Figures (1-4), a circuit board placement rack includes a main placement box 1, with side placement boxes 2 on both sides of the main placement box 1. The main placement box 1 and the side placement boxes 2 have placement grooves 11 on their tops. The main placement box 1 has a first sliding groove 13 on its side. A first sliding rod 21 is slidably disposed in the first sliding groove 13. A first bolt 15 is screwed onto the first sliding rod 21. A plurality of first slots 14 are arranged on the inner wall of the first sliding groove 13. One end of the first bolt 15 can be inserted into the first slot 14, and the other end extends out of the first sliding groove 13 and is slidably connected to the first sliding groove 13. One end of the first sliding rod 21 is fixedly connected to the side placement box 2.

[0018] Multiple pairs of rollers 12 are rotatably arranged on the inner wall of the placement slot 11. The placement slots 11 on the main placement box 1 and the side placement box 2 can be combined into a complete rectangular groove. A support frame 3 is provided above the main placement box 1. Side adjustment frames 31 are provided on both sides of the support frame 3. A connecting rod 32 is provided between the side adjustment frame 31 and the support frame 3. One end of the connecting rod 32 is located inside the support frame 3 and is slidably connected to the support frame 3. The other end is fixedly connected to the side of the side adjustment frame 31. A second sliding rod 22 is fixedly provided at the bottom of the side adjustment frame 32.

[0019] The side-mounted box 2 has a second sliding groove 23, and the second sliding rod 22 is slidably connected to the second sliding groove 23. A second bolt 25 is screwed onto the second sliding rod 22. Several second slots 24 are arranged on the inner wall of the second sliding groove 23. One end of the second bolt 25 can be inserted into the second slot 24, and the other end protrudes from the second sliding groove 23 and is slidably connected to the first sliding groove 13. The support frame 3 is a rectangular frame structure, and a top cover 4 is provided on the support frame 3. A fixing bolt 41 is screwed onto the top cover 4. The support frame 3 has screw holes 33 for fixing the bolt 41. A protective pad 42 is provided at the bottom of the top cover 4. A groove is provided at the top of the fixing bolt 41, and a protrusion is provided at the bottom of the main placement box 1 for inserting into the groove.

[0020] In use, the position of the side placement box 2 is adjusted according to the size of the circuit board to be placed. After adjusting the position of the side placement box 2, the first bolt 15 is rotated so that one end of the first bolt 15 enters the first slot 14, restricting the movement of the first slide rod 21 in the first slide groove 13, thereby fixing the position of the side placement box 2. The circuit board is then inserted into the placement groove 11 of the main placement box 1, with both ends of the circuit board inserted into the placement groove 11 on the side placement box 2. During the insertion process, the rollers 12 on the inner wall of the placement groove 11 can reduce the contact between the circuit board and the inner wall of the placement groove, preventing the circuit board from being inserted too far into the groove. During the placement process, friction with the inner wall can damage the circuit board. Some circuit boards may leak out from the top of the placement slot after being inserted. To prevent the upper placement box from squeezing the lower circuit board during stacking, the height of the support frame 3 can be adjusted upwards and fixed by screwing the second bolt 25 into the second slot 24. At the same time, the top cover 4 is installed on the support frame 3 by screwing the fixing bolt 41 into the screw hole 33 of the support frame 3. When stacking the placement boxes, the protrusion at the bottom of the upper placement box can be inserted into the groove at the top of the fixing bolt 41 on the lower top cover 4 for stacking.
