[0023] The present invention will be further described below with reference to the accompanying drawings and specific embodiments to aid in understanding its content. Unless otherwise specified, the methods used in this invention are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0024] Please refer to Figures 1-4. A PCB board turnover device includes a placement rack 1. The placement rack 1 has two partitions 2 inside. Horizontal plates 3 are provided on both the left and right sides of the upper surface of the placement rack 1. The placement rack 1 has two adjustment mechanisms with the same structure inside. Limiting mechanisms are provided between the outer walls of the two partitions 2 and the inner wall of the placement rack 1, as well as on the opposite sides of the two horizontal plates 3.

[0025] The limiting mechanism includes a side plate 301 fixedly connected to the upper end face of the two horizontal plates 3, a movable plate 302 disposed inside the right side plate 301, a threaded rod 303 that passes through and is threadedly connected to the outer wall of the right side plate 301 and is movably connected to the movable plate 302 through a bearing, and a plurality of placement plates 304 fixedly connected to the opposite side of the left horizontal plate 3 and the movable plate 302.

[0026] The adjustment mechanism includes a slide groove 202 opened inside the placement frame 1, a slide rod 204 fixedly connected inside the slide groove 202, a slider 203 slidably connected to the outer wall of the slide rod 204 and fixedly connected to the two partitions 2, a spring 205 installed on the outer wall of the slide rod 204 and located between the two sliders 203, and between the two sliders 203 and the inner wall of the slide groove 202.

[0027] In this embodiment: the movable partition 2 can be adjusted according to the different sizes of the PCB board, so that the partition 2 drives the slider 203 to slide on the outer wall of the slide bar 204. At the same time, the spring 205 is compressed or stretched. The space for placing the PCB board can be adjusted by adjusting the two partitions 2 and the distance between the partitions 2 and the placement rack 1. The PCB board can be placed separately and classified according to different types, specifications or production batches. PCB boards of the same type and specification can be placed in the same space, which helps to quickly identify and locate the required PCB board during the transfer process and improves the transfer efficiency.

[0028] A large PCB board is placed between two side plates 301, and multiple large PCB boards are placed on the upper surfaces of two placement plates 304 located on the same horizontal plane. By rotating the threaded rod 303, the threaded rod 303 pushes the moving plate 302 to move, causing the moving plate 302 to move the placement plate 304 on its outer wall until the distance between the left side plate 301 and the moving plate 302 matches the large PCB board. This can limit and fix the large PCB board, improving the stability of turnover.

[0029] As a technical optimization of this utility model, the left and right sides of the outer walls of the two partitions 2 are provided with second placement grooves 201, and the left and right sides of the inner walls of the placement rack 1 are provided with first placement grooves 102 that are flush with the second placement grooves 201.

[0030] In this embodiment, the first placement slot 102 and the second placement slot 201 located on the same plane facilitate the smooth separation and placement of the PCB board in the placement rack 1. By separating the PCB boards, it can be ensured that the PCB boards will not come into contact with each other during transportation, thereby avoiding scratch damage caused by surface friction.

[0031] As a technical optimization of this utility model, anti-slip pads are provided on the outer wall of the placement plate 304 and the inner walls of the first placement groove 102 and the second placement groove 201.

[0032] In this embodiment, the stability of the PCB board placement can be further ensured by setting anti-slip pads.

[0033] As a technical optimization of this utility model, the bottom of the slider 203 and the placement frame 1 are detachably connected by bolts.

[0034] In this embodiment, the position of the slider 203 can be limited and fixed by bolts, which makes it easier for the slider 203 to drive the partition 2 to move under the elastic force of the spring 205, thus affecting the stability of the PCB board placement.

[0035] As a technical optimization of this utility model, slots 101 are provided on both the left and right sides of the upper surface of the placement rack 1, and the bottom ends of the two horizontal plates 3 are fixedly connected with insert plates 305 that match the slots 101. The insert plates 305 and the placement rack 1 are detachably connected by bolts.

[0036] In this embodiment: the insert plate 305 is inserted into the slot 101, and the insert plate 305 can be fixed or removed by bolts, thereby realizing the installation or removal of the horizontal plate 3.

[0037] As a technical optimization of this utility model, the height of the partition 2 is lower than the height of the side wall of the placement rack 1.

[0038] In this embodiment, by making the height of the partition 2 lower than the height of the side wall of the placement rack 1, the partition 2 can be prevented from blocking the PCB boards placed on the two horizontal plates 3.

[0039] The working principle and usage process of this utility model are as follows: The movable partition 2 can be moved according to the different sizes of the PCB board, so that the partition 2 drives the slider 203 to slide on the outer wall of the slide rod 204. At the same time, the spring 205 is compressed or stretched. The space for placing the PCB board can be adjusted by adjusting the two partitions 2 and the distance between the partitions 2 and the placement rack 1. The slider 203 is then fixedly connected to the placement rack 1 by bolts. The PCB boards can be placed separately and classified according to different types, specifications or production batches. PCB boards of the same type and specification can be placed in the same space, which helps to quickly identify and locate the required PCB boards during the transfer process and improves the transfer efficiency.

[0040] A large PCB board is placed between two side plates 301, and multiple large PCB boards are placed on the upper surfaces of two placement plates 304 located on the same horizontal plane. By rotating the threaded rod 303, the threaded rod 303 pushes the moving plate 302 to move, causing the moving plate 302 to move the placement plate 304 on its outer wall until the distance between the left side plate 301 and the moving plate 302 matches the large PCB board. This can limit and fix the large PCB board, improving the stability of turnover.

[0041] In the description of this utility model, it should be understood that the terms "left", "right", "up", "down", "top", "bottom", "front", "back", "inner", "outer", "back", "middle", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0042] However, the above description is only a specific embodiment of this utility model and should not be construed as limiting the scope of implementation of this utility model. Therefore, any substitution of equivalent components or equivalent changes and modifications made in accordance with the scope of protection of this utility model should still fall within the scope of the claims of this utility model.
